英語, 研究論文(学術雑誌), We surveyed the status of the secondary finding (SF) disclosure in comprehensive genome profiling (CGP) in 2020. The situation has changed: increase in the number of hospitals that provide CGP, an update to the Comprehensive Tumor Genomic Profiling: Materials for Review of Secondary Findings (CTGPMRSF), and the addition of a liquid biopsy test, FoundationOne® Liquid CDx (F1L). Moreover, the actual situation was unclear because the 2020 survey did not include all designated and cooperative hospitals. Herein, we conducted a questionnaire survey of all designated-core, designated, and cooperative hospitals to identify the current status and challenges concerning SF in the CGP in 2022. A total of 82.1% of the hospitals responded and 77.7% of the response was from cooperative hospitals. Approximately 80% of the hospitals used CTGPMRSF. SF disclosure, confirmatory test implementation, and SF confirmation rates were 12.4%, 31.6%, and 46.6% for FoundationOne® CDx (F1CDx), respectively, and 6.8%, 31.8%, and 70.7% for F1L, respectively. The implementation rate of the confirmatory test was substantially higher in hospitals with genetic experts and in hospitals that could conduct confirmatory tests on the same day. Our survey provides insight into how SF is handled in Japan. The percentage of cases leading to confirmatory tests has gradually increased, although challenges such as insurance coverage limitations and varied understanding of SF among patients and healthcare providers persist. With the increasing use of whole-genome analysis, our findings will provide valuable insights into establishing an effective SF disclosure system. - Dyssegmental dysplasia Rolland-Desbuquois type is caused by pathogenic variants in HSPG2 - a founder haplotype shared in five patients.

英語, 研究論文(学術雑誌), Dyssegmental dysplasia (DD) is a severe skeletal dysplasia comprised of two subtypes: lethal Silverman-Handmaker type (DDSH) and nonlethal Rolland-Desbuquois type (DDRD). DDSH is caused by biallelic pathogenic variants in HSPG2 encoding perlecan, whereas the genetic cause of DDRD remains undetermined. Schwartz-Jampel syndrome (SJS) is also caused by biallelic pathogenic variants in HSPG2 and is an allelic disorder of DDSH. In SJS and DDSH, 44 and 8 pathogenic variants have been reported in HSPG2, respectively. Here, we report that five patients with DDRD carried four pathogenic variants in HSPG2: c.9970 G > A (p.G3324R), c.559 C > T (p.R187X), c7006 + 1 G > A, and c.11562 + 2 T > G. Two patients were homozygous for p.G3324R, and three patients were heterozygous for p.G3324R. Haplotype analysis revealed a founder haplotype spanning 85,973 bp shared in the five patients. SJS, DDRD, and DDSH are allelic disorders with pathogenic variants in HSPG2. - 遺伝性乳癌卵巣癌患者の血縁者に対する遺伝カウンセリング受診勧奨のために克服すべき課題

英語, 研究論文(学術雑誌), OBJECTIVE: This study examined how clients' selection and preference for noninvasive prenatal testing (NIPT) for aneuploidy changed with genetic counseling (GC) performed by certified geneticists at a primary hospital specializing in obstetrics, where other multiple prenatal genetic tests options were available. METHODS: A total of 334 couples who underwent GC between 2017 and 2019 were included in the study. The average age of the pregnant women who underwent GC was 35.1 years. RESULTS: Among the 95 couples (28.4%) who wanted NIPT at the start of GC, 10 (10.5%) switched to other tests, and 4 (4.2%) chose not to undergo any test. Among the 106 (31.7%) couples who wanted the combination of ultrasonography and the serum marker test, 12 (11.3%) chose not to undergo the test. Among the 92 (27.5%) couples who were undecided before GC, 21 (22.8%) wanted NIPT, 31 (33.7%) selected combined tests, and 18 (19.6%) did not undergo any test. CONCLUSION: We have demonstrated the significance of GC before prenatal genetic testing under widespread use of NIPT. Ideally, obstetric facilities should provide GC, or at least, pre-counseling at their own facilities, and offer multiple prenatal genetic testing options or refer to other facilities for the same. - 【図説 産婦人科医のための臨床遺伝学必修知識I】Secondary Findingsの取り扱い方

英語, 研究論文(学術雑誌), In genetic counseling, information must be provided in ways that the client and general public can understand to ensure that decisions are made autonomously. To realize this, we must assess the extent of knowledge held by the general public regarding genetics. To identify the client's original knowledge before genetic counseling, we explored the fundamental knowledge related to genetic counseling that is taught in Japanese compulsory education. A qualitative study was conducted. We selected 50 textbooks for compulsory education (Japanese, social studies, science, health and physical education, technology and home economics, morality, and life) that had been used in more than half of the districts in Japan. The text data were analyzed using qualitative content analysis, and quantitative data were analyzed for methodological triangulation. Codes, subcategories, and categories were generated from the contexts that met the following criteria: the contents included in the official textbook for clinical geneticists, contents derived from such descriptions that were related to genetic counseling, and contents clearly related to genetics. Among the 50 textbooks, 33 textbooks contained fundamental knowledge regarding genetic counseling. A qualitative content analysis identified four major categories: (1) basics of genetics, (2) understanding and control of diseases, (3) efforts and barriers to the realization of a harmonious society, and (4) technology and humans. We found that fundamental knowledge related to genetic counseling is directly or indirectly taught in compulsory education. Our results are an important resource for understanding the client's knowledge baseline and will be helpful for effective genetic counseling. - 高度生殖補助医療(ART)経験の有無による出生前検査の知識や意識についての検討

Frontiers in reproductive health, 5, 1098464, 1098464, 2023年, [国際誌]
英語, 研究論文(学術雑誌), INTRODUCTION: The aim of the study was to describe the factors influencing the reproductive decision-making of carrier parents after the diagnosis of an inherited metabolic disorder in newborn screening in Japan. METHODS: We conducted a semi-structured interview with 12 parents and analyzed data based on content analysis methodology. RESULTS: We identified 11 factors, including personal evaluation of recurrence risk, understanding of hereditary phenomena, concerns and desires for future planned children, concerns for older siblings, perceptions of diseases, degree of acceptance and denial of diseases, the opinions of others on having another child, optimism/faith in positive outcomes, self-evaluation of parental capability, factors unrelated to the disease, and the "right" time to expand the family. DISCUSSION: Perceptions and acceptance of disease are both important factors in reproductive decision-making, though these factors fluctuate continuously during the childbearing period. Therefore, effective reproductive genetic counseling will be considerate of the parents' fluctuating perceptions on reproduction. To ensure that the decision-making process is for the benefit of the parents and future children, long-term involvement of health care professionals is needed to assess the client's acceptance of the disease and their understanding of genetic phenomena and recurrence rates. - Challenges of secondary finding disclosure in genomic medicine in rare diseases: A nation-wide survey of Japanese facilities outsourcing comprehensive genetic testing.

英語, 研究論文(学術雑誌), Comprehensive genome analysis may reveal secondary findings (SFs) including pathogenic variants of genes other than those originally targeted. Comprehensive genetic analysis of rare diseases is generally performed as research in Japan. Therefore, the status and difficulties in SF disclosure remain unclear. To obtain information for the appropriate disclosure of SFs in rare diseases, we conducted a survey on how SFs are handled in clinical practice by facilities that outsource comprehensive genetic testing to other facilities. The response rate was 66.7% (40/60). Among the responding facilities, 55% had a policy of disclosing SFs with clinical utility and considered targeting actionable SFs with high penetrance. These facilities had difficulties in determining the disclosure targets (51%) and in genetic counseling (38%). Improving genetic literacy, establishment of surveillance systems, and providing insurance coverage for medical care to unaffected carriers were commonly cited as solutions to these difficulties. A comparison of the willingness to disclose SFs between overseas and in Japan showed more reluctance in Japan (86% vs. 65% for actionable SFs and 62% vs. 16% for non-actionable SFs). The group with difficulty in determining disclosure targets was significantly more likely to discuss this at conferences with other facilities and to refer guidelines. This suggests that the group with difficulties was unable to make decisions solely at their own facility and sought collaboration with other facilities. These findings suggest the necessity for a system that allows consultation with experts across facilities and guidelines that set forth policies for determining SFs. - 腫瘍組織検査とリキッドバイオプシーにおける生殖細胞系列バリアントの検証シーケンス

英語, 研究論文(学術雑誌), BACKGROUND: Somatic and germline variants are not distinguishable by circulating tumor DNA (ctDNA) testing without analyzing non-tumor samples. Although confirmatory germline testing is clinically relevant, the criteria for selecting presumed germline variants have not been established in ctDNA testing. In the present study, we aimed to evaluate the prevalence of pathogenic germline variants in clinical ctDNA testing through their variant allele fractions (VAFs). METHODS: A total of consecutive 106 patients with advanced solid tumors who underwent ctDNA testing (Guardant360®) between January 2018 and March 2020 were eligible for this study. To verify the origin of pathogenic variants reported in ctDNA testing, germline sequencing was performed using peripheral blood DNA samples archived in the Clinical Bioresource Center in Kyoto University Hospital (Kyoto, Japan) under clinical research settings. RESULTS: Among 223 pathogenic variants reported in ctDNA testing, the median VAF was 0.9% (0.02-81.8%), and 88 variants with ≥ 1% VAFs were analyzed in germline sequencing. Among 25 variants with ≥ 30% VAFs, seven were found in peripheral blood DNA (BRCA2: n = 6, JAK2: n = 1). In contrast, among the 63 variants with VAFs ranging from 1 to < 30%, only one variant was found in peripheral blood DNA (TP53: n = 1). Eventually, this variant with 15.6% VAF was defined to be an acquired variant, because its allelic distribution did not completely link to those of neighboring germline polymorphisms. CONCLUSION: Our current study demonstrated that VAFs values are helpful for selecting presumed germline variants in clinical ctDNA testing. - Mortality and morbidity of infants with trisomy 21, weighing 1500 grams or less, in Japan.

英語, 研究論文(学術雑誌), Although very low birth weight (VLBW) is well studied in neonatology and the perinatal prognosis of VLBW infants has improved over time, little is known about the prognosis of VLBW infants with trisomy 21 (T21). We aimed to investigate the mortality and morbidity of VLBW infants with T21 during NICU admission in Japan, in comparison to those of infants without birth defects (BD-). Maternal and neonatal data of infants weighing 1500 grams or less admitted to the centers of the Neonatal Research Network of Japan from 2003 to 2016 were collected prospectively. Of 60,136 infants, 328 (0.55%) had T21. Although maternal age in the case of T21 infants was higher, maternal complications tended to be less frequent than in those with BD-. Multivariable analysis revealed that morbidities were higher in infants with T21 than in those with BD- but respiratory distress syndrome and retinopathy of prematurity were less frequent in those with T21 (p < 0.001, and p = 0.014, respectively), and no significant difference was observed between the two groups in the proportion of late-onset circulatory collapse of prematurity as well as cystic periventricular leukomalacia (p = 0.739 and p = 0.733, respectively). The survival rate at discharge from the NICU was 77% and 94% for T21 and BD-, respectively. This was the first nationwide survey of VLBW infants with T21 in Japan. Although there were no data regarding the timing of diagnosis, these data will aid prenatal genetic counseling and perinatal management of T21 infants. - AYA世代の血友病推定保因者女性に対する遺伝カウンセリングの重要性

英語, 研究論文(学術雑誌), In June 2019, the Japanese National Health Insurance (NHI) system introduced coverage for two types of tumor genomic profiling (TGP): FoundationOneⓇ CDx (F1) and OncoGuide™ NCC OncoPanel System (NCCOP). TGP sometimes reveals germline variants that are potentially pathogenic as secondary findings (SFs). We conducted a questionnaire-based survey to find out the operational statuses of F1 and NCCOP at institutions where TGP was performed to elucidate issues related to SFs. Responses were received from 97 of 112 institutions (86.6%). As of May 31, 2020, 88 (90.7%) and 78 (80.4%) institutions started performing F1 and NCCOP, respectively. Since F1 only examines tumor samples, germline confirmatory testing is necessary to determine whether they are actually germline pathogenic variants (GPVs). When physicians are obtaining informed consent all but 2.3% of the patients requested SF disclosure. Conversely, when presumed germline pathogenic variants (PGPVs) were detected, 46.2% were not willing to receive confirmatory tests as they wanted to prioritize cancer treatment over SFs investigation, while only 23.3% underwent confirmatory tests. Problems in cancer genomic medicine reported by clinical genetics departments included short-staffing (n = 10), insufficient interdepartmental cooperation (n = 9), inconsistent understanding of genetics among healthcare professionals (n = 8), and low utilization rate of SFs due to lack of insurance coverage for confirmatory tests and post-test health checkups (n = 8). Solutions include; determining the appropriate timing to confirm patient intent on SF disclosure, covering confirmatory tests for PGPVs by the NHI, and establishing cooperation between the oncology and clinical genetics departments. - 一般集団における出生前検査について知識についての調査研究

英語 - Physicians' perceptions of the factors influencing disclosure of secondary findings in tumour genomic profiling in Japan: a qualitative study.

European journal of human genetics : EJHG, 30, 1, 88, 94, 2021年08月16日, [国際誌]
英語, 研究論文(学術雑誌), Tumour genomic profiling (TGP), conducted in search of therapeutics, sometimes reveals potentially pathogenic germline variants as secondary findings (SFs). Physicians involved in TGP are often specialised in oncology and not in clinical genetics. To better utilise SFs, we explored issues physicians have during disclosure and the potential for collaborations with clinical genetics professionals. Semi-structured interviews were conducted with 14 physicians who had experience in handling outpatient TGP at designated core hospitals for cancer genomic medicine in Japan. The data were analysed thematically. The difficulties physicians experienced during informed consent (IC) included educating patients about SFs, providing detailed information on SFs, and explaining the impact of SFs on patients' family members. When SFs were detected, physicians had reservations regarding the relevance of the disclosure criteria. Confirmatory germline tests were performed using peripheral blood when tumour-only tests detected suspected SFs. Some physicians had reservations about the necessity of confirmatory tests when they did not affect the patients' treatment options. To encourage patients to receive confirmatory tests, improvements are necessary in the healthcare system, such as insurance reimbursements, education for physicians so that they can provide a better explanation to their patients, and genetic literacy of physicians and patients. The physicians offered insights into the challenges they experienced related to IC, disclosure of SFs, and expectations for active collaborations with clinical genetics professionals. Wider healthcare insurance coverage and better genetic literacy of the population may lead to more patients taking confirmatory tests when SFs are suspected. - Evaluation of the clinical performance of noninvasive prenatal testing at a Japanese laboratory.

英語, 研究論文(学術雑誌), AIM: We aimed to evaluate the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of noninvasive prenatal testing (NIPT) in high-risk pregnant women. METHODS: Pregnant women who underwent GeneTech NIPT, the most commonly used NIPT in Japan, between January 2015 and March 2019, at Japan NIPT Consortium medical sites were recruited for this study. The exclusion criteria were as follows: pregnant women with missing survey items, multiple pregnancy/vanishing twins, chromosomal abnormalities in the fetus other than the NIPT target disease, and nonreportable NIPT results. Sensitivity and specificity were calculated from the obtained data, and maternal age-specific PPV and NPV were estimated. RESULTS: Of the 45 504 cases, 44 263 cases fulfilling the study criteria were included. The mean maternal age and gestational weeks at the time of procedure were 38.5 years and 13.1 weeks, respectively. Sensitivities were 99.78% (95% confidence interval [95% CI]: 98.78-99.96), 99.12% (95% CI: 96.83-99.76), and 100% (95% CI: 88.30-100) for trisomies 21, 18, and 13, respectively. Specificities were more than 99.9% for trisomies 21, 18, and 13, respectively. Maternal age-specific PPVs were more than 93%, 77%, and 43% at the age of 35 years for trisomies 21, 18, and 13, respectively. CONCLUSION: The GeneTech NIPT data showed high sensitivity and specificity in the detection of fetal trisomies 21, 18, and 13 in high-risk pregnant women, and maternal age-specific PPVs were obtained. These results could provide more accurate and improved information regarding NIPT for genetic counseling in Japan. - 日本人のPALB2遺伝子変異による遺伝性乳癌における検討

英語, 研究論文(学術雑誌), Trisomy 18 (T18) and trisomy 13 (T13) are major concerns in prenatal genetic testing due to their poor prognosis; very low birth weight (VLBW) is also a concern in neonatology. The aim of this study was to investigate the mortality and morbidity of VLBW infants diagnosed with T18/T13 in Japan, compared with those with no birth defects (BD-). Maternal and neonatal data were collected prospectively from infants weighing <1501 g and were admitted to centers of the Neonatal Research Network of Japan during 2003 to 2016. Among 60,136 infants, 563 and 60 was diagnosed with T18 and T13, respectively. Although the age of mothers of infants with T18/T13 was higher, the frequency of maternal complications was lower than those with BD-. With maternal and neonatal characteristic adjustments, T18/T13 had a higher incidence of each morbidity when compared with BD-. Mortality rates in the NICU were 70, 77, and 5.8% for T18, T13, and BD-, respectively, while the survival discharge rates of T18 and T13 were 29.5 and 23.3%, respectively, which was significantly higher than previous reports. This was the first nationwide survey for VLBW infants with T18/T13 in Japan; this novel data will be relevant and useful for prenatal genetic counseling and perinatal management. Although T18/T13 were considered to be fatal in the past, with proper epidemiological information, discussions with affected families, and compassionate patient care, the mortality rate of T18/T13 can be improved. - 【新型コロナウイルス関連特集】診療面(実践報告5) 各遺伝子医療部門の取り組み 遠隔診療に取り組んでいる施設 京都大学医学部附属病院遺伝子診療部におけるCOVID-19流行下における遠隔遺伝カウンセリング体制

英語, 研究論文(学術雑誌), Despite the recommendations of the latest guidelines, the practical efficacy of universal screening for identifying Lynch syndrome (LS) among patients with colorectal cancer (CRC) may be limited in the real world due to infrequent referrals and the difficulties of genetic testing. Thus, the present study aimed to retrospectively analyze the results of universal screening of patients with CRC at a referral hospital in Japan. Immunohistochemistry was performed for mismatch repair proteins [including DNA mismatch repair protein MSH6 (MSH6), mismatch repair endonuclease PMS2 (PMS2), DNA mismatch repair protein Msh2 (MSH2) and DNA mismatch repair protein Mlh1 (MLH1)] and BRAF V600E mutation. Tumors that showed the following were considered to indicate LS and patients with such tumors were designated as genetic testing candidates (GTCs): i) Loss of MSH6/MSH2; ii) loss of MSH6 alone; iii) loss of PMS2 alone; and iv) loss of PMS2/MLH1 with negative BRAF V600E. MLH1 methylation and BRAF V600E mutation were analyzed in deficient mismatch repair (dMMR) tumors retrospectively. The frequency of dMMR and GTCs in an independent cohort of patients with young-onset CRC were also investigated. Universal screening revealed dMMR tumors, GTCs and LS probands in 7.3, 3.9 and 0.4%, respectively, of 463 patients with CRC. Although dMMR tumors were observed in both younger (<50 years) and older (≥60 years) patients, the GTCs were enriched in younger individuals. Evaluation of mismatch repair status in an independent cohort confirmed the high rate of GTCs in patients with young-onset CRC. The low detection rate of LS demonstrated in this study questions the implementation of routine universal screening in regions with low prevalence of LS. Considering the enrichment of GTCs in young-onset CRCs, age-restricted strategies may be simple and efficient practical alternatives to universal screening in the real world. - Optimization of prediction methods for risk assessment of pathogenic germline variants in the Japanese population.

英語, 研究論文(学術雑誌), OBJECTIVE: Maternal characteristics and neonatal outcomes associated with cell-free DNA (cfDNA) results were analysed retrospectively to assess the details of false-positive and false-negative results after initial blood sampling in non-invasive prenatal testing (NIPT). STUDY DESIGN: A multicentre retrospective study was performed for women undergoing NIPT who received discordant cfDNA results between April 2013 and March 2018. The NIPT data obtained using massive parallel sequencing were studied in terms of maternal background, fetal fraction, z-scores, invasive procedure results and neonatal outcomes after birth. RESULTS: Of the 56,545 women who participated in this study, 54 false-positive (0.095 %) and three false-negative (0.006 %) cases were found. Seven of the 54 false-positive cases (13.0 %) had vanishing twin on ultrasonography. Among the 18 false-positive cases of trisomy 18, confined placental mosaicism (CPM) was confirmed in three cases (16.7 %), while CPM was present in one of the three false-negative cases of trisomy 21. CONCLUSION: These data suggest that the incidence of women with false-positive or false-negative results is relatively low, that such false results can often be explained, and that vanishing twin and CPM are potential causes of NIPT failure. Genetic counselling with regard to false results is important for clients prior to undergoing NIPT. - Morphofunctional cardiac changes in singleton and twin pregnancies: a longitudinal cohort study.

英語, 研究論文(学術雑誌), BACKGROUND: This study aimed to compare the echocardiographic changes and cardiac biomarkers between women with singleton and twin pregnancies. METHODS: From April 2014 to March 2016, this longitudinal cohort study invited pregnant women who were scheduled to give birth at Hokkaido University Hospital. We analyzed prospectively collected data on simultaneously determined echocardiographic parameters and blood cardiac markers of 44 women with singleton and 22 women with twin pregnancies. Furthermore, we tested the mixed-effect models for echocardiographic parameters and cardiac biomarkers. RESULTS: During the third trimester and immediately postpartum (within 1 week after childbirth), the mean left atrial volume index and brain natriuretic peptide (BNP) level were significantly higher in women with twin pregnancies than in those with singleton pregnancies. Women with twin pregnancies also had significantly smaller second-trimester inferior vena cava diameters and significantly higher third-trimester creatinine levels than those with singleton pregnancies. BNP positively correlated with the left atrial volume index (β = 0.49, p < 0.01) and the ratio of early diastolic transmitral to mitral annular velocity (E/e') (β = 0.41, p < 0.01). At 1 month after childbirth in women with singleton pregnancies, BNP and N-terminal precursor protein BNP (NT-proBNP) fragments immediately postpartum negatively correlated with the later E/e' (r = - 0.33, p = 0.02 and r = - 0.36, p < 0.01, respectively). CONCLUSIONS: The intravascular cardiac load reached maximum within 1 week after childbirth and was greater in women with twin pregnancies than in those with singleton pregnancies. BNP/NT-proBNP significantly positively correlated with LA volume index and E/e'. In women with singleton pregnancies, BNP secreted immediately after childbirth might improve the diastolic functions 1 month after childbirth. - Epidemiology of Birth Defects in Very Low Birth Weight Infants in Japan

英語, 研究論文(学術雑誌), OBJECTIVE: To evaluate the mortality and morbidity of very low birth weight (VLBW) preterm infants with birth defects in Japan. STUDY DESIGN: Data were collected prospectively for infants weighing <1501 g and born at <37 weeks of gestation admitted to centers of the Neonatal Research Network of Japan during 2003-2016. We compared outcomes of infants with and without birth defects using Pearson χ2 test, Wilcoxon rank-sum test, log-rank test, nominal logistic regression analysis, and stratified analysis by birth defect subgroups. This study was approved by the Ethics Committee of Kyoto University Graduate School and Faculty of Medicine. RESULTS: Among 57 730 VLBW preterm infants, 3557 infants (6.2%) were born with birth defects. Chromosomal abnormalities, congenital heart defects, and congenital malformation of the digestive system were the most common categories. Among diseases, Trisomy 18, Down syndrome, and cleft palate were the most prevalent. There were significant differences between perinatal characteristics of infants with and without birth defects. Most categories of morbidity occurred more frequently in infants with birth defects compared with those without birth defects. The aOR for mortality during the neonatal intensive care unit admission was 10.6 (95% CI 9.5-11.7) for infants with birth defects. A stratified analysis identified birth defect categories with good, moderate, and poor prognoses. CONCLUSIONS: This detailed information about mortality and morbidity of preterm VLBW infants with birth defects should be useful for genetic counseling as well as prenatal and neonatal care, with the limitation that we lacked information about the timing of diagnosis, abortion, or stillbirth. - 出生前遺伝学的検査と遺伝カウンセリング体制の構築 超音波検査の活用について

英語, 研究論文(学術雑誌), The management of secondary findings (SFs), which are beyond the intended purpose of the analysis, from clinical comprehensive genomic analysis using next generation sequencing (NGS) presents challenges. Policy statements regarding their clinical management have been announced in Japan and other countries. In Japan, however, the current status of and attitudes of clinical genetics professionals toward reporting them are unclear. We conducted a questionnaire survey of clinical genetics professionals at two time points (2013 and 2019) to determine the enforcement of the SF management policy in cases of comprehensive genetic analysis of intractable diseases and clinical cancer genome profiling testing. According to the survey findings, 40% and 70% of the respondents stated in the 2013 and 2019 surveys, respectively, that they had an SF policy in the field of intractable diseases, indicating that SF policy awareness in Japan has changed significantly in recent years. Furthermore, a total of 80% of respondents stated that their facility had established a policy for clinical cancer genome profiling testing in the 2019 survey. In both surveys, the policies included the selection criteria for genes to be disclosed and the procedure to return SFs, followed by recommendations and proposals regarding SFs in Japan and other countries. To create a better list of the genes to be disclosed, further examination is needed considering the characteristics of each analysis. - Current status and legal/ethical problems in the research use of the tissues of aborted human fetuses in Japan.

英語, 研究論文(学術雑誌), BACKGROUND: To date there is no law regulating the research use of human aborted fetuses in Japan. OBJECTIVE: The aim was to review the current status with historical background and legal/ethical problems limiting the research use of the tissues of aborted human fetuses. METHOD: We reviewed literature via PubMed, Web of Science, Scopus, Japana Centra Revuo Medicina and CiNii, reports from various committees and research groups from Ministry of Health, Labour and Welfare (MHLW), and domestic books. RESULTS: Aborted human fetal tissues used for research purposes were first documented in the 1920s. The first guideline, the Peel Code was released in 1972. Since then, in Western countries, the research use of aborted fetuses has been less restricted compared with that of embryos, due to the following guidelines outlined by expert groups. Currently, aborted fetal tissues are commercially available for research purposes in the US. In Japan, only four indications are presented in "a public statement permitting research use of deceased fetuses' and 'neonates' organs etc." (1987). In the 2000s, expert committees of the MHLW concluded that research use of human aborted fetuses should be discontinued, and that comprehensive rules and independent regulations should be implemented. This issue has not been discussed in the Japanese legislature since 2003. DISCUSSION: Establishment of laws and guidelines for this issue is insufficient not only in Japan but also in other countries. It is important to secure transparency for making laws and guidelines and in obtaining public understanding. This article is protected by copyright.

英語, Although alkaline phosphatase (ALP) activity is relatively low in carriers of recessive type hypophosphatasia (HPP), most are asymptomatic and therefore do not undergo medical evaluations. We analyzed the association of ALP-encoding ALPL variants with serum ALP and bone traits in the general Japanese population. Study participants (n = 9671) were from the Nagahama Study, which was a longitudinal cohort study of an apparently healthy general Japanese population. ALPL variants were analyzed by whole-genome sequencing or TaqMan probe assays using DNA extracted from peripheral blood samples. The speed of sound in calcaneal bone was assessed by quantitative ultrasound (QUS) and used as surrogate measures of bone mineral density. We identified 13 ALPL variants. Minor allele frequencies of three variants were higher than expected. Variant c.529G > A has been reported as a possible pathogenic variant for adult type HPP. Variants c.979C > T and c.1559delT are reported as pathogenic variants for perinatal severe HPP or infantile HPP. The allele frequencies of c.529G > A, c.979C > T, and c.1559delT were 0.0107, 0.0040, and 0.0014, respectively. Serum ALP activity was significantly lower and differed among the three variants (P < 0.001), as well as between individuals with and without any of the three variants (P < 0.001). Serum ALP activity was inversely associated with QUS values, although no direct association was observed between the ALPL variants and QUS values. An association between serum ALP activity and QUS was confirmed; however, we failed to detect an association between ALPL variants and bone traits in the general Japanese population. - Qualitative investigation of the factors that generate ambivalent feelings in women who give birth after receiving negative results from non-invasive prenatal testing.

英語, 研究論文(学術雑誌), BACKGROUND: Women who receive negative results from non-invasive prenatal genetic testing (NIPT) may find that they later have mixed or ambivalent feelings, for example, feelings of accepting NIPT and regretting undergoing the test. This study aimed to investigate the factors generating ambivalent feelings among women who gave birth after having received negative results from NIPT. METHODS: A questionnaire was sent to women who received a negative NIPT result, and a contents analysis was conducted focusing on ambivalent expressions for those 1562 women who responded the questionnaire. The qualitative data gathered from the questionnaire were analyzed using the N-Vivo software package. RESULTS: Environmental factors, genetic counseling-related factors, and increased anticipatory anxiety, affected the feeling of ambivalence among pregnant women. Furthermore, pregnant women desired more information regarding the detailed prognosis for individuals with Down syndrome and living with them and/or termination, assuming the possibility that they were positive. CONCLUSIONS: Three major interrelated factors affected the feeling of ambivalence in women. Highlighting and discussing such factors during genetic counseling may resolve some of these ambivalences, thereby enhancing the quality of decisions made by pregnant women. - A familial case of alveolar capillary dysplasia with misalignment of the pulmonary veins: The clinicopathological features and unusual glomeruloid endothelial proliferation.

英語, 研究論文(学術雑誌), We present two unrelated Japanese pedigrees with achondrogenesis type 1b (ACG1B), characterized by prenatally lethal fetal hydrops and severe micromelia. The affected members in these pedigrees carried a common homozygous missense point mutation in solute carrier family 26 member 2 (SLC26A2), a gene associated with ACG1B (NM_000112:c.1987G>A). This loss-of-function point mutation causes substitution of glycine 663 with arginine in a highly conserved loop domain of SLC26A2. Interestingly, only a few cases of this mutation have been registered in Japanese genomic databases, and there are no reports of this mutation in any major genomic databases outside Japan. Furthermore, we confirmed the presence of a homozygous stretch of approximately 75 kb surrounding the pathogenic variant. Our findings suggest that this missense point mutation in SLC26A2, which is likely the cause of the ACG1B phenotypes in these unrelated fetuses, is distributed exclusively in Japan. - 【最新遺伝医学研究と遺伝カウンセリング シリーズ4 最新小児・周産期遺伝医学研究と遺伝カウンセリング】(第2章)小児・周産期遺伝医学研究・診療各論 周産期編 出生前遺伝学的検査で認められる染色体異常

研究論文(学術雑誌), In tumor-only next-generation sequencing (NGS), identified variants have the potential to be secondary findings (SFs), but they require verification through additional germline testing. In the present study, 194 patients with advanced cancer who underwent tumor-only NGS between April 2015 and March 2018 were enrolled, and the incidences of possible and true SFs were evaluated. Among them, 120 patients (61.9%) harbored at least one possible SF. TP53 was the most frequent gene in which 97 variants were found in 91 patients (49.5%). Nine patients provided informed consent to undergo additional germline testing, and a total of 14 variants (BRCA1, n = 1; BRCA2, n = 2; PTEN, n = 2; RB1, n = 1; SMAD4, n = 1; STK11, n = 1; TP53, n = 6) were analyzed. Three variants (BRCA1, n = 1; BRCA2, n = 2) were confirmed to be SFs, whereas TP53 variants were confirmed to be somatic variants. To confirm the low prevalence of SFs in TP53, we analyzed 24 patients with TP53 variants who underwent a paired tumor–normal NGS assay. As expected, all TP53 variants were confirmed to be somatic variants. A total of 30 patients were tested for germline variants in TP53, but none of them resulted in true SFs, suggesting the low prevalence of SFs in this gene. Therefore, the significance of additional germline testing for TP53 variants appears to be relatively low in daily clinical practice using a tumor-only NGS assay, unless patients have any relevant medical or family history. - リンチ症候群の免疫染色スクリーニング(Immunostaining screening for Lynch syndrome)

英語, 研究論文(学術雑誌), Genome editing of the human embryo using CRISPR/Cas9 has the potential to prevent hereditary diseases from being transmitted to the next generation. However, attitudes to this technology have not been examined sufficiently among the genetic professionals who will use it in the near future. We conducted a questionnaire survey of Japanese clinical geneticists and certified genetic counselors. Differences were observed between them in their recognition of this technology and impressions on its difficulty and cost. Both groups worried about misuse of it, with insufficient information and rules. As key elements for such rules, they considered ethics, safety, and purpose. Most disapproved of modifying physical traits as an enhancement, though they hoped for the treatment of severe diseases. At current clinical sites, they tended to adopt a prudent attitude by mentioning only the possibility of genome editing in the future. Academic policies and legislation are required, especially for application in human embryos, through a consensus of professionals and general citizens. Furthermore, professionals should maintain awareness of new developments and regularly reexamine attitudes for the ongoing development of more suitable rules, education systems, and clinical protocols. As preparation for changes, opportunities to address ethical issues and initiate discussions are also required. - Fetal middle cerebral artery peak systolic velocity as a predictor of fetal anemia in unselected women giving birth at or near term.

英語, 研究論文(学術雑誌), OBJECTIVE: This study was performed to evaluate the application of fetal middle cerebral artery peak systolic velocity (MCA-PSV) for prediction of newborn anemia with umbilical cord blood hemoglobin concentration at birth (UCB-Hb) < 10.0 g/dL among infants born at gestational week (GW) ≥ 36 to unselected women. MATERIALS AND METHODS: We reviewed the medical charts of 699 women giving birth to singleton infants at GW ≥ 36 with available data on MCA-PSV measured at GW ≥ 25 at the discretion of the attending physician. Multiple of the median (MoM) MCA-PSV (MCA-PSV MoM) > 1.5 was defined as a positive MCA-PSV test result. RESULTS: The MCA-PSV test was applied 2309 times (313 and 1996 times during second and third trimesters, respectively) in 699 women. The results were positive in 4.4% (102/2309) of tests and at least once in 9.9% (69/699) of women. Anemic infants were born to one (1.4%) and six (1.0%) of 69 and 630 women with and without at least one positive test result, respectively. MoM determined 4, 3, and 2 weeks before birth showed significant weak negative correlations with UCB-Hb at birth (correlation coefficient: 0.298-0.325). CONCLUSIONS: Among unselected women giving birth at or near term, the MCA-PSV test was unsatisfactory for prediction of newborn anemia in this retrospective observational study. - Investigating the role of genetic counseling in neuromuscular disease considering life events.

英語, 研究論文(学術雑誌), OBJECTIVE: To evaluate the reasons for nonreportable cell-free DNA (cfDNA) results in noninvasive prenatal testing (NIPT), we retrospectively studied maternal characteristics and other details associated with the results. METHODS: A multicenter retrospective cohort study in pregnant women undergoing NIPT by massively parallel sequencing (MPS) with failed cfDNA tests was performed between April 2013 and March 2017. The women's data and MPS results were analyzed in terms of maternal characteristics, test performance, fetal fraction (FF), z scores, anticoagulation therapy, and other details of the nonreportable cases. RESULTS: Overall, 110 (0.32%) of 34 626 pregnant women had nonreportable cfDNA test results after an initial blood sampling; 22 (20.0%) cases had a low FF (<4%), and 18 (16.4%) cases including those with a maternal malignancy, were found to have altered genomic profile. Approximately half of the cases with nonreportable results had borderline z score. Among the women with nonreportable results because of altered genomic profile, the success rate of retesting using a second blood sampling was relatively low (25.0%-33.3%). Thirteen (11.8%) of the women with nonreportable results had required hypodermic heparin injection. CONCLUSIONS: The classification of nonreportable results using cfDNA analysis is important to provide women with precise information and to reduce anxiety during pregnancy. - Secondary findings in clinical cancer genome sequencing

英語, 研究論文(学術雑誌), © 2018 Wiley Periodicals, Inc. Special AT-rich sequence-binding protein 2 (SATB2)-associated syndrome (SAS) is characterized by alterations of SATB2. Its clinical features include intellectual disability and craniofacial abnormalities, such as cleft palate, dysmorphic features, and dental abnormalities. Here, we describe three previously undiagnosed, unrelated patients with SAS who exhibited dental abnormalities, including multiple odontomas. Although isolated odontomas are common, multiple odontomas are rare. Individuals in families 1 and 3 underwent whole-exome sequencing. Patient 2 and parents underwent targeted amplicon sequencing. On the basis of the hg19/GRCh37 reference and the RefSeq mRNA NM_001172517, respective heterozygous mutations were found and validated in Patients 1, 2, and 3: a splice-site mutation (chr2:g.200137396C > T, c.1741-1G > A), a nonsense mutation (chr2:g.200213750G > A, c.847C > T, p.R283*), and a frame-shift mutations (chr2:g.200188589_200188590del, c.1478_1479del, p.Q493Rfs*19). All mutations occurred de novo. The mutations in Patients 1 and 3 were novel; the mutation in Patient 2 has been described previously. Tooth mesenchymal cells derived from Patient 2 showed diminished SATB2 expression. Multiple odontomas were evident in the patients in this report; however, this has not been recognized previously as a SAS-associated phenotype. We propose that multiple odontomas be considered as an occasional manifestation of SAS. - Correction: Maternal age-specific risk for trisomy 21 based on the clinical performance of NIPT and empirically derived NIPT age-specific positive and negative predictive values in Japan.

英語, 研究論文(学術雑誌), The data collected by nation-wide study of noninvasive prenatal genetic testing (NIPT) for trisomy 21 from 21,610 pregnant women with advanced maternal age in Japan were reported. Among 188 NIPT-positive cases, 180 cases were true positive. The incidence of aneuploidy according to maternal age was estimated using a state-space model. Although, the frequency of trisomy increased exponentially with maternal age as previously reported, the maternal age-specific risk for trisomy 21 that was based on the clinical performance of NIPT was lower than the predicted risk in previous Western cohorts based on the data from invasive prenatal testing (Bayesian two-sided tail-area probability P = 0.0156). The empirical positive predictive value (PPV) of NIPT is likely to turn out higher than that of the theoretical PPV calculated from the sensitivity/specificity of the test and the incidence of trisomy 21 from this study. - 産科一次施設において出生前診断の相談を受ける際の問題点

英語, 研究論文(学術雑誌), OBJECTIVE: The purpose of this study is to compare the fetal fractions during non-invasive prenatal testing (NIPT) in singleton pregnancies according to gestational age and maternal characteristics to evaluate the utility of this parameter for the prediction of pregnancy complications including gestational diabetes mellitus (GDM) and hypertensive disorders of pregnancy (HDP). STUDY DESIGN: This study was a multicenter prospective cohort study. The present data were collected from women whose NIPT results were negative. The relationships between the fetal fractions and the gestational age, maternal weight and height, and incidences of miscarriage, preterm delivery, and pregnancy complications including GDM, HDP and placental abruption were assessed. RESULTS: A total of 5582 pregnant women with verified NIPT negative results were registered in the study. The demographic characteristics of the study populations were statistically analyzed, and the women with HDP tended to have a low fetal fraction in samples taken during early gestation. The area under the curve (AUC) in a receiver operating characteristic curve (ROC) analysis was 0.608 for women with HDP. CONCLUSION: A low fetal fraction on NIPT might be correlated with future HDP. However, predicting HDP during early pregnancy in women with a low fetal fraction might be difficult. - A novel heterozygous ITGB3 p.T720del inducing spontaneous activation of integrin αIIbβ3 in autosomal dominant macrothrombocytopenia with aggregation dysfunction.

英語, 研究論文(学術雑誌), We identified a novel heterozygous ITGB3 p.T720del mutation in a pedigree with macrothrombocytopenia exhibiting aggregation dysfunction. Platelet aggregation induced by ADP and collagen was significantly reduced, while ristocetin aggregation was normal. Integrin αIIbβ3 was partially activated in a resting status, but platelet expression of αIIbβ3 was downregulated. Functional analysis using a cell line showed spontaneous phosphorylation of FAK in αIIb/β3 (p.T720del)-transfected 293T cells in suspension conditions. Abnormal cytoplasmic protrusions, membrane ruffling, and cytoplasmic localization of αIIbβ3 were observed in αIIb/β3 (p.T720del)-transfected CHO cells. Such morphological changes were reversed by treatment with an FAK inhibitor. These findings imply spontaneous, but partial, activation of αIIbβ3 followed by phosphorylation of FAK as the initial mechanism of abnormal thrombopoiesis. Internalization and decreased surface expression of αIIbβ3 would contribute to aggregation dysfunction. We reviewed the literature of congenital macrothrombocytopenia associated with heterozygous ITGA2B or ITGB3 mutations. Reported mutations were highly clustered at the membrane proximal region of αIIbβ3, which affected the critical interaction between αIIb R995 and β3 D723, resulting in a constitutionally active form of the αIIbβ3 complex. Macrothrombocytopenia caused by a heterozygous activating mutation of ITGA2B or ITGB3 at the membrane proximal region forms a distinct entity of rare congenital thrombocytopenia. - 各種の治療で対応したvon Willebrand病合併妊娠の3例

英語, 研究論文(学術雑誌), Objective: Women with hypertensive disorders of pregnancy (HDP) show elevated risk of heart failure despite decreased circulating plasma volume compared with those with normotensive control pregnancies (NCP). This study was performed to better characterise the heart in women with HDP and determine whether high-sensitivity troponin I (hs-TnI) around childbirth predicts reduced left ventricular (LV) relaxation at 1 month postpartum. Methods: Echocardiography was performed longitudinally during the first, second and third trimesters and immediately postpartum within 1 week and 1 month postpartum in 24 women with HDP, with simultaneous determination of blood variables in comparison with 51 women with NCP. Results: Compared with NCP, HDP showed greater antepartum left atrial (LA) volume, LV mass and inferior vena cava (IVC) diameter, higher peripartum brain natriuretic peptide/N-terminal pro-B-type natriuretic peptide and hs-TnI with the highest value immediately postpartum, and lower early diastolic mitral annular velocity (e') during pregnancy/postpartum. In analyses of data on HDP and NCP, hs-TnI at the third trimester as well as that immediately postpartum was negatively correlated with later e' at 1 month postpartum. The areas under the receiver operating characteristic curves were 0.82 and 0.81 for hs-TnI at the third trimester and immediately postpartum, respectively, in the prediction of reduced LV relaxation at 1 month postpartum. Conclusion: Reduced LV diastolic function and decreased splanchnic blood reservoir may contribute to the increased third trimester IVC diameter and LA volume in women with HDP. The rise in hs-TnI around childbirth was associated with poor LV relaxation ability at 1 month postpartum. - Morphofunctional cardiac changes in pregnant women: associations with biomarkers.

英語, 研究論文(学術雑誌), Objective: This longitudinal study was performed to determine changes in echocardiography parameters in association with various biomarker levels in pregnancy/postpartum. Methods: Fifty-one healthy pregnant women underwent echocardiography with simultaneous determination of blood levels of five biomarkers at each of the first, second and third trimesters of pregnancy, immediately postpartum within 1 week after childbirth and approximately 1 month postpartum. Data on 255 echocardiography scans (five times per woman) and biomarkers were analysed. Results: Left ventricular end-diastolic dimension, left atrial (LA) volume index and left ventricular (LV) mass index increased with advancing gestation and reached the maximum immediately postpartum concomitant with the highest brain natriuretic peptide (BNP), N-terminal pro B-type natriuretic peptide (NT-proBNP), high-sensitivity troponin I (hs-TnI) and creatine kinase MB levels. The inferior vena cava diameter was significantly reduced in the third trimester compared with that in the first trimester and the peak occurred immediately after childbirth. In 255 paired measurements, hs-TnI level was significantly positively correlated with LA volume index and LV mass index; BNP and NT-proBNP were significantly positively correlated with LA volume index and estimated glomerular filtration rate (eGFR) was significantly positively correlated with the average of early diastolic septal and lateral mitral annular velocity (e'). Conclusions: Maximal cardiac changes in morphology occurred postpartum within 1 week after childbirth, not during pregnancy. BNP/NT-proBNP, hs-TnI and eGFR reflected cardiac changes in pregnancy. - フローサイトメトリーを用いた胎児赤血球計量系の構築

英語, 研究論文(学術雑誌), There have been few reports on the effects of everolimus on the fetus, but none of six infants with documented everolimus exposure in utero had congenital malformations. A 32-year-old nulliparous woman on everolimus (5.0mg/day) for renal angiomyolipoma (AML) due to tuberous sclerosis complex (TSC) was found to be pregnant at gestational week (GW) 7-5/7, at which time everolimus was withheld. To control AML in this patient, transarterial embolization was performed in the right and left kidneys at GW 21 and 24, respectively, and everolimus was reinitiated at GW 25. The patient gave birth at GW 37 to a normally formed infant weighing 3057g, but who had cardiac tumors thought to be rhabdomyomas due to inherited TSC. Thus, although data are still limited, everolimus may be promising with respect to teratogenicity. Everolimus concentration in the maternal and umbilical cord blood at birth was 1.1ng/mL and 1.0ng/mL, respectively. - Current status of non-invasive prenatal testing in Japan

英語, 研究論文(学術雑誌), AimThe purpose of this study was to report the 3-year experience of a nationwide demonstration project to introduce non-invasive prenatal testing (NIPT) of maternal plasma for aneuploidy, and review the current status of NIPT in Japan.
MethodsTests were conducted to detect aneuploidy in high-risk pregnant women, and adequate genetic counseling was provided. The clinical data, test results, and pregnancy outcomes were recorded. We discuss the problems of NIPT on the basis of published reports and meta-analyses.
ResultsFrom April 2013 to March 2016, 30613 tests were conducted at 55 medical sites participating in a multicenter clinical study. Among the 30613 women tested, 554 were positive (1.81%) and 30021 were negative (98.1%) for aneuploidy. Of the 289, 128, and 44 women who tested positive for trisomies 21, 18, and 13, respectively, and underwent definitive testing, 279 (96.5%), 106 (82.8%), and 28 (63.6%) were determined to have a true-positive result. For the 13481 women with negative result and whose progress could be traced, two had a false-negative result (0.02%). The tests were performed on the condition that a standard level of genetic counseling be provided at hospitals.
ConclusionHere, we report on the 3-year nationwide experience with NIPT in Japan. It is important to establish a genetic counseling system to enable women to make informed decisions regarding prenatal testing. Moreover, a welfare system is warranted to support women who decide to give birth to and raise children with chromosomal diseases. - Serum placental growth factor and soluble fms-like tyrosine kinase 1 at mid-gestation in healthy women: Association with small-for-gestational-age neonates

英語, 研究論文(学術雑誌), Aim This study was performed to determine the associations between serum placental growth factor (PlGF) and soluble fms-like tyrosine kinase 1 (sFlt-1) levels at mid-gestation with the risk of small-for-gestational-age (SGA) neonates born at gestational week (GW) 36 in healthy women.
Methods PlGF and sFlt-1 concentrations were determined at GW 24-27 in 183 women with births at GW36, but without gestational diabetes mellitus and hypertension.
Results Thirteen (7.1%) SGA neonates were born. Median (range) GW at blood sampling was similar between women with and without SGA (25 [24-25] and 24 [24-27], respectively, P = 0.671). Pre-pregnancy body mass index (BMI) and PlGF levels were significantly lower in women with than without SGA, while sFlt-1 levels and sFlt-1:PlGF ratio (sFlt-1/PlGF) did not differ significantly between the two groups. PlGF and sFlt-1/PlGF, but not BMI or sFlt-1, showed significant correlations with birthweight z-score; the correlation was positive for PlGF and negative for sFlt-1/PlGF. Women with PlGF level< 10th percentile and those with sFlt-1/PlGF level> 90th percentile showed significantly increased risk of SGA compared to those with respective counterpart characteristics; relative risk was 3.8 (95% confidence interval, 1.3-11.3; 21% [4/19] vs 5.5% [9/164]) for PlGF and 7.9 (95% confidence interval, 3.0-20.8, 33.3% [6/18] vs 4.2% [7/165]) for sFlt-1/PlGF.
Conclusion Maternal PlGF and sFlt-1/PlGF determined during GW 24-27 were associated with the risk of SGA neonates born at GW >= 36, even in women with uncomplicated pregnancies. - Effects of childbirth on podocyturia in women with normotensive, uncomplicated pregnancies

英語, 研究論文(学術雑誌), Changes in hemodynamics and blood pressure occur shortly before and after childbirth regardless of the mode of delivery. This study aimed to test the hypothesis that parturition induces a temporal increase in podocyturia monitored by podocyte-specific protein podocin mRNA expression levels (Pod-mRNA). A total of 105 urine specimens, consisting of 43 and 62 from 18 and 20 otherwise healthy women with vaginal delivery (VD) and elective cesarean delivery (ECS), respectively, were studied. Determination of urine protein and creatinine (Cr) concentrations and quantitative analyses of Pod-mRNA, nephrin mRNA (Nep-mRNA), synaptopodin mRNA (Syn-mRNA), and aquaporin 2 mRNA expression were performed using RT-PCR in pelleted urine samples. Levels of mRNA expression were corrected by urine Cr concentration. Podocyturia increased significantly, concomitant with a significantly decreased Nep:Pod-mRNA ratio (NPR) in the urine, collected immediately before or after childbirth regardless of the delivery mode compared with urine collected before commencement of labor or on postpartum day 3 or later. Podocyturia was significantly negatively correlated with NPR [correlation coefficient (r) =-0.614/-0.750 for VD/ECS women, respectively], as well as the Syn:Pod-mRNA ratio. Systolic blood pressure exceeded 140 mmHg during labor in 50% of VD women, and mean arterial pressure was significantly positively correlated with podocyturia during labor in VD women (r = 0.733). Thus parturition induces a transient increase in urine podocytes with reduced Nep- and Syn-mRNA expressions. Glomerular podocytes with reduced Nep- and Syn-mRNA levels were suggested to be likely to detach from the glomerular basement membrane around childbirth. - 分娩を繰り返すと、妊婦は妊娠糖尿病(GDM)になりやすくなるか?

英語, 研究論文(学術雑誌), Aim: Urine podocin mRNA expression and urine podocin : nephrin mRNA expression ratio (PNR) increase with increasing proteinuria during pregnancy complicated with pre-eclampsia (PE). This suggests that urine podocytes with reduced nephrin mRNA expression are abundant in pathological podocyturia. The aim of this study was therefore to determine post-partum changes in podocyturia and PNR in relation to proteinuria after pre-eclampsia (PE).
Methods: A total of 137 peripartum urine specimens, consisting of 72 and 65 from 24 and 30 women with PE and normotensive control pregnancies (NCP), respectively, were studied. Determination of urine protein and creatinine concentration and quantitative analysis of podocyte-specific podocin and nephrin mRNA expression were carried out using reverse transcription-polymerase chain reaction in pelleted urine samples. Podocyturia was monitored via urine podocin mRNA expression. Podocyturia and proteinuria were normalized by urine creatinine concentration.
Results: Podocyturia and urine PNR decreased with decreasing proteinuria as well as with increasing time after delivery in the urine from PE women. In physiological proteinuria (i.e. protein : creatinine ratio [P/Cr] 0.005-0.1 mg/mg), however, both podocyturia and PNR were significantly greater in the urine from PE women compared with NPC women, although P/Cr was similar between the groups (median, 0.037 mg/mg for PE vs 0.029 mg/mg for NCP).
Conclusions: Podocyturia decreases with decreasing proteinuria in PE women after childbirth. In PE women, however, pathological podocyturia consisting of podocytes with decreased nephrin mRNA expression persisted even after proteinuria decreased to a level similar to that in NCP women. - Effects of childbirth on podocyturia in women with normotensive, uncomplicated pregnancies

英語, 研究論文(学術雑誌), Changes in hemodynamics and blood pressure occur shortly before and after childbirth regardless of the mode of delivery. This study aimed to test the hypothesis that parturition induces a temporal increase in podocyturia monitored by podocyte-specific protein podocin mRNA expression levels (Pod-mRNA). A total of 105 urine specimens, consisting of 43 and 62 from 18 and 20 otherwise healthy women with vaginal delivery (VD) and elective cesarean delivery (ECS), respectively, were studied. Determination of urine protein and creatinine (Cr) concentrations and quantitative analyses of Pod-mRNA, nephrin mRNA (Nep-mRNA), synaptopodin mRNA (Syn-mRNA), and aquaporin 2 mRNA expression were performed using RT-PCR in pelleted urine samples. Levels of mRNA expression were corrected by urine Cr concentration. Podocyturia increased significantly, concomitant with a significantly decreased Nep:Pod-mRNA ratio (NPR) in the urine, collected immediately before or after childbirth regardless of the delivery mode compared with urine collected before commencement of labor or on postpartum day 3 or later. Podocyturia was significantly negatively correlated with NPR [correlation coefficient (r) = -0.614/-0.750 for VD/ECS women, respectively], as well as the Syn:Pod-mRNA ratio. Systolic blood pressure exceeded 140 mmHg during labor in 50% of VD women, and mean arterial pressure was significantly positively correlated with podocyturia during labor in VD women (r = 0.733). Thus parturition induces a transient increase in urine podocytes with reduced Nep- and Syn-mRNA expressions. Glomerular podocytes with reduced Nep- and Syn-mRNA levels were suggested to be likely to detach from the glomerular basement membrane around childbirth. - Effect of urine creatinine level during pregnancy on dipstick test

英語, 研究論文(学術雑誌), Aim: Dipstick results for proteinuria are affected by urine concentration, and thus urine creatinine concentration ([Cr]). This study was performed to determine whether spot urine [Cr] changes significantly during pregnancy, leading to a significantly different false-negative rate (FNR) on dipstick test between trimester.
Methods: The [Cr] and protein concentrations ([P]) were analyzed in 631 spot urine samples with negative/equivocal dipstick from 425 pregnant women. False-negative dipstick was defined as [P] : [Cr] ratio (P/Cr) > 0.27 mg/mg.
Results: Median [Cr] was 117 mg/dL (range, 6.5-326 mg/dL), 72 mg/dL (range, 4.3-477 mg/dL), and 73 mg/dL (range, 8.4-396 mg/dL) in the first (n = 96), second (n = 344), and third (n = 191) trimester urine samples, respectively (P = 0.000, Kruskal-Wallis). Both [P] and P/Cr increased significantly with advancing gestation. FNR 9.4% (18/191) in the third trimester was significantly higher than that of 0.0% (0/96) in the second trimester and that of 0.5% (2/344) in the third trimester. In the 20 urine samples with false-negative dipstick, median [Cr] was 47.0 mg/dL (range, 11.0-358 mg/dL) and the proportion of samples with dilute urine, that is, [Cr] <47 mg/dL, was significantly higher than in the remaining 611 urine samples (50%, 10/20 vs 28%, 174/611, respectively, P = 0.046).
Conclusions: Urine samples in the second and third trimesters were more likely to be diluted compared with the first trimester. This was associated with high FNR in third trimester urine samples. - Maternal bradycardia occurring prior to onset of HELLP syndrome in a woman with pre-eclampsia.

英語, 研究論文(学術雑誌), A 36-year-old nulliparous woman developed pre-eclampsia at gestational week (GW) 28-6/7 Cardiac status was checked regularly. Heart rate of 93 beats per minute (bpm) with left atrial diameter (LAD) of 35 mm, left ventricular hypertrophy and inferior vena cava diameter (IVCD) of 8 mm at GW 32-0/7 decreased to 48 bpm with an expanded IVCD to 25 mm, dilated left atrium (LAD to 39 mm), increased pulmonary arterial pressure, increased systemic vascular resistance (approximate 3000 dyn s/cm5) and biphasic intrarenal venous flow pattern 3.5 hours prior to childbirth at GW 32-3/7 Epigastralgia, tachycardia (160 bpm) and marked hypertension (201/111 mm Hg) occurring 2 hours after echocardiography necessitated caesarean section, with subsequent development of HELLP syndrome. Acute fluid shift from the splanchnic vasculature to central vasculature may have occurred causing HELLP syndrome as a result from vasospasm associated with sympathetic hyperactivity. The cause of bradycardia prior to tachycardia remains unclear. - NIPTから推定した本邦におけるトリソミー頻度とNIPTの経験的陽性的中率及び陰性的中率

英語, 研究論文(学術雑誌), Aim: This study was performed to determine risk factors for central serous chorioretinopathy (CSC) in pregnant women.
Methods: This retrospective observational study was performed in a cohort of all 1881 women giving birth at a single center. The hospital database was searched to abstract all women diagnosed with pre-eclampsia (PE) as well as those visiting the eye clinic during the current pregnancy. Medical chart review was performed in all women diagnosed with CSC and PE.
Results: PE developed in 73 (3.9%) women, six (8.2%) of whom visited the eye clinic for problems occurring in the current pregnancy; 47 of 1808 (2.6%) women without PE visited the eye clinic (P = 0.015). Four women were identified as having developed CSC after onset of PE, and none of those without PE developed CSC (5.5% [4/73] vs 0.0% [0/1808], respectively, P < 0.0001). Stepwise regression analysis selected four risk factors for CSC: hematocrit value > 38.0% (odds ratio [OR], 22.9; 95% confidence interval [CI], 2.12-247), serum creatinine > 0.7 mg/dL (OR, 21.7; 95% CI, 1.12-422), time interval from diagnosis of PE until delivery > 14 days (OR, 20.0; 95% CI, 1.87-214), and urine protein : creatinine ratio (mg/mg) > 4.5 (OR, 15.7; 95% CI, 0.81-304). Hematocrit value-38.0% was finally identified as the only independent risk factor (OR, 22.9; 95% CI, 2.12-1716) for CSC in PE women.
Conclusion: CSC was likely to occur in PE women, especially in those with hemoconcentration as a result of plasma leakage from the circulating blood due to increased vascular permeability. - Increased podocyturia in pregnant women compared to non-pregnant women

英語, 研究論文(学術雑誌), Aim: Hyperfiltration is a cause of podocyturia and occurs physiologically in the kidney of pregnant women. Podocyturia is increased in preeclamptic pregnancies, but it is unclear whether there is also any increase in uncomplicated pregnancies. This study was performed to examine whether podocyturia and urine aquaporin 2 mRNA expression are increased in healthy pregnant women (PW) compared to healthy non-pregnant women (NPW).
Methods: Eleven urines obtained from 11 NPW and longitudinal 76 urines from 40 PW with uncomplicated pregnancies (median number [range] of urine samples/person, 2 [1 - 3]) were studied. Determination of protein and creatinine concentrations and number of cells in urine other than blood cells, and quantitative analyses of the mRNA expression of aquaporin 2 (AQP2-mRNA), podocin (Pod-mRNA), and nephrin (Nep-mRNA) were performed using RT-PCR in pelleted urine samples. Podocyturia was monitored with urine Pod- and Nep-mRNA expression levels normalized relative to creatinine.
Results: Urine cell density and urine AQP2-, Pod-, and Nep-mRNA expression normalized relative to creatinine were significantly higher in PW than NPW. The number of cells per milligram of creatinine was significantly positively correlated with expression of all three mRNAs with correlation coefficients (R-value) of 0.442, 0.481, and 0.561 for Pod-, Nep-, and AQP2-mRNA, respectively. AQP2-mRNA expression was strongly (R > 0.8) positively correlated with both Pod- and Nep-mRNA expression.
Conclusion: Podocyturia monitored by Pod- and Nep-mRNA expression and urine cells expressing AQP2-mRNA were increased in uncomplicated pregnancies compared to healthy non-pregnant women. Urine cells expressing AQP2-mRNA increased with increasing podocyturia in healthy women. - Parental serum alkaline phosphatase activity as an auxiliary tool for prenatal diagnosis of hypophosphatasia

英語, 研究論文(学術雑誌), ObjectiveThe objective of this study is to clarify the usefulness of parental alkaline phosphatase (ALP) for prenatal diagnosis of hypophosphatasia (HPP).
MethodsMaternal (m) and paternal (p) ALP values were measured in 77 cases from a multicenter cohort (fetal skeletal dysplasia forum in Japan) of cases with short limbs on ultrasonography during pregnancy. After birth, X-rays, cord blood ALP, and gene analysis were evaluated to achieve an exact diagnosis. The screening usefulness of ALP was examined retrospectively.
ResultsSeventeen cases were eventually diagnosed as HPP and 60 as not HPP; the overall mean m-ALP and p-ALP (standard deviation) values were 133.4 (53) versus 197 (69) IU/L and 149.6 (71.8) versus 231 (61.4) IU/L (p<0.001). Receiver operating characteristic curve analysis showed that the optimal m-ALP and p-ALP cutoff values were 123 and 165IU/L, respectively. Presence of at least one of the m-ALP or p-ALP values abnormally low had a sensitivity, specificity, and positive predictive values of 82% (14/17), 93%, and 78%, respectively, for the diagnosis of HPP.
ConclusionParental ALP measurement might be an auxiliary tool to hone in the prenatal diagnosis of fetal HPP. (c) 2017 John Wiley & Sons, Ltd. - 日本超音波医学会としての胎児形態観察項目を考える 日本産科婦人科学会推奨項目との関係 本邦における超音波検査による胎児診断の現状に関する調査

英語, 研究論文(学術雑誌), OBJECTIVE. In 2011, we collected data on fetal CT radiation dose to determine the diagnostic reference level (DRL)
however, continuous evaluation of the DRL is necessary. The hypothesis of this study is that the fetal CT radiation dose has decreased, and we predict a widespread use of iterative reconstruction (IR). We also predict that the national decrease in exposure is because of the DRL reported as a result of the previous national study. MATERIALS AND METHODS. Various testing protocols from each site were summarized as part of the study results. The minimum, one-fourth (25th percentile), median, three-fourths (75th percentile), and maximum values were obtained for volume CT dose index (CTDIvol), dose-length product (DLP), and scan length of 120 fetal CT examinations. The trends for IR usage and tube voltage were also investigated. RESULTS. Compared to the results of the 2011 study (n = 119), the minimum, 25th percentile, median, and 75th percentile values for CTDIvol and DLP have decreased for the tabulated results in 2015 (n = 120). The 75th percentile value for CTDIvol was 4.9 mGy, which is 43% of the previous value. IR was used in 70% of the sites. The radiation dose was significantly lower among groups that used IR. CONCLUSION. Four years passed between our initial survey on DRL and the present follow-up survey, and it appears that the previous report sufficiently fulfilled its objective and role in contributing to the decrease in DRL observed in this follow-up study. - 妊婦血液の血小板自然凝集塊形成についての検討

英語, 研究論文(学術雑誌), AimThis retrospective study was performed to determine the frequency of malformed infants born at a tertiary center in Hokkaido, Japan. The accuracy of prenatal diagnosis rates was also investigated.
MethodsAn observational study was performed using data of 1509 and 1743 newborn infants at a single center during two study periods, 2005-2009 (first) and 2010-2014 (second), respectively. Cases including minor anomalies (accessory auricle, nevus and fistula auris congenita) were not included.
ResultsIn total, 274 and 569 malformations were identified in 191 and 337 newborn infants in the first and second study periods, respectively. The number of malformed infants increased significantly over time (13% [191/1509] vs 19% [337/1743], respectively; P < 0.001), mainly as a result of an increase in cases of congenital heart disease (CHD), from 59 to 141 (31% [59/191] vs 42% [141/337] of all malformed infants in the first and second periods, respectively). The overall accurate prenatal diagnosis rate improved over time from 47% (128/274) to 58% (329/569) because of significant improvements in accurate prenatal diagnosis of CHD subtypes (23% [16/70] vs 65% [151/232] in the first and second periods, respectively, P < 0.0001).
ConclusionsThe frequency of malformed newborns was higher in the tertiary center than in the general population. The increased number of cases with prenatal suspicion and diagnosis of CHD contributed to the increased frequency of malformed infants during the study period. - 妊娠・分娩に伴う尿中podocyte排泄量の変化

英語, 研究論文(学術雑誌), EZH2 inhibition and reactivation of tumor suppressor microRNAs (miRNAs) represent attractive anti-cancer therapeutic strategies. We found that EZH2-suppressed let 7b and miR-361, two likely tumor suppressors, inhibited endometrial cancer (EC) cell proliferation and invasion, and abrogated cancer stem cell-like properties. In EC cells, EZH2 induced and functioned together with YY1 to epigenetically suppress miR-361, which upregulated Twist, a direct target of miR361. Treating EC cells with GSK343, a specific EZH2 inhibitor, mimicked the effects of siRNA-mediated EZH2 knockdown, upregulating miR-361 and downregulating Twist expression. Combining GSK343 with 5 AZA-2'-deoxycytidine synergistically suppressed cell proliferation and invasion in vitro, and decreased tumor size and weight in EC cell xenografted mice. Quantitative real-time PCR analysis of 24 primary EC tissues showed that lower let-7b and miR-361 levels were associated with worse patient outcomes. These results were validated in a larger EC patient dataset from The Cancer Genome Atlas. Our findings suggest that EZH2 drives EC progression by regulating miR-361/Twist signaling, and support EZH2 inhibition as a promising anti-EC therapeutic strategy. - Liver dysfunction in women with pregnancy-induced antithrombin deficiency

英語, 研究論文(学術雑誌), AimPodocyte depletion in the kidney is associated with end-stage kidney disease (ESKD). Pre-eclampsia (PE) increases the risk of ESKD in later life. This study was performed to determine whether nephrinuria (soluble nephrin in the urine) is correlated with proteinuria and/or podocyturia (podocytes in the urine) in PE women.
MethodsEighty-three urine samples, consisting of 45 and 38 samples from 27 normotensive and nine PE women, respectively, underwent simultaneous determination of nephrin, protein, and creatinine concentrations in the urine supernatant and quantitative analysis of podocyte-specific protein mRNA expression. This included podocin (Pod-mRNA) and nephrin (Nep-mRNA), using real-time polymerase chain reaction in the pelleted urine. Nephrinuria and proteinuria were corrected by creatinine concentration. Pod- and Nep-mRNA expression levels were corrected by GAPDH.
ResultsNephrinuria, proteinuria, Pod-mRNA expression, and Nep-mRNA expression all increased with advancing gestation in PE women, while not in normotensive women. The nephrinuria was strongly correlated with proteinuria (R= 0.901, P < 0.001), Pod-mRNA expression level (R=0.824, P<0.001), and Nep-mRNA expression level (R = 0.724, P < 0.001) in urine samples from PE women, while the nephrinuria was significantly correlated with proteinuria alone (R = 0.419, P < 0.005) in urine samples from normotensive women.
ConclusionNephrinuria reflected well the degrees of proteinuria and podocyturia in PE women. This suggested that increased nephrinuria/proteinuria was associated with podocyte loss in the kidneys of PE women. - 【周産期のウイルス感染症】 妊娠・分娩・産褥時の対応 C型肝炎

英語, The purpose of this study is to summarize the results from a survey on awareness of genetic counseling for pregnant women who wish to receive non-invasive prenatal testing (NIPT) in Japan. As a component of a clinical study by the Japan NIPT Consortium, genetic counseling was conducted for women who wished to receive NIPT, and a questionnaire concerning both NIPT and genetic counseling was given twice: once after pre-test counseling and again when test results were reported. The responses of 7292 women were analyzed. They expressed high satisfaction with the genetic counseling system of the NIPT Consortium (94%). The number of respondents who indicated that genetic counseling is necessary for NIPT increased over time. Furthermore, they highly valued genetic counseling provided by skilled clinicians, such as clinical geneticists or genetic counselors. The vast majority (90%) responded that there was sufficient opportunity to consider the test ahead of time. Meanwhile, women who received positive test results had a poor opinion and expressed a low-degree satisfaction. We confirmed that the pre-test genetic counseling that we conducted creates an opportunity for pregnant women to sufficiently consider prenatal testing, promotes its understanding and has possibilities to effectively facilitate informed decision making after adequate consideration. A more careful and thorough approach is considered to be necessary for women who received positive test results. - Factors affecting parental decisions to terminate pregnancy in the presence of chromosome abnormalities: a Japanese multicenter study

英語, 研究論文(学術雑誌), Objective To investigate the rates of termination of pregnancy ( TOP) for fetal chromosomal abnormalities and factors related to such parental decision in Japan.
Methods A multicenter retrospective cohort study of chromosomal abnormalities diagnosed before 22 weeks of gestation between April 2008 and March 2015. The pregnancy outcomes and parental decisions were investigated.
Results Among 931 fetuses with chromosome abnormalities, the total TOP rate was 75.1% (699/931). TOP rates were 89.3% (585/655) in autosomal aneuploidies and 40.8% (51/125) in sex chromosome aneuploidies. Trisomy 21 showed the highest TOP rate (93.8% [390/416]) followed by trisomy 18 (84.5% [163/193]) and trisomy 13 (71.9% [23/32]). Indications for karyotyping were related to a parental decision for TOP (P < 0.01): in cases of autosomal aneuploidy, with fetal abnormal ultrasound findings as the reference value, diagnoses made following positive results at non-invasive prenatal testing (adjusted odds ratio [OR]: 13.7, 95% confidence interval [CI] 4.07-45.9) and those because of advanced maternal age (adj. OR 2.91, 95% CI 1.15-7.35) were significantly more frequent.
Conclusions In Japan, pregnancies with fetal trisomy 21 are more likely to result in TOP when diagnosed in utero than any other chromosome anomaly. The indications for prenatal karyotyping strongly affect the decision to TOP.

英語, 研究論文(学術雑誌), This prospective observational study compare urine nephrin: creatinine ratio (NCR, ng/mg) with serum soluble fms-like tyrosine kinase-1: placental growth factor ratio (FPR, pg/pg) for preeclampsia (PE) prediction among unselected asymptomatic pregnant women in 2nd trimester. NCR and FPR were determined in 254 paired urine/blood samples collected simultaneously from 254 women at median gestational week (GW) 24 (range, 22-27) without hypertension or significant proteinuria in pregnancy (SPIP). Fifteen (5.9%) developed SPIP and hypertension at GW 34.0 (26.0-38.6) and 35.3 (27.6-38.6), respectively, and were diagnosed with PE at GW 35.7 (27.6-38.6). The 90th percentile level determined in 239 women normotensive throughout pregnancy gave NCR (139) sensitivity and positive predictive values (PPV) of 60% (9/15) and 27% (9/33), while those for serum FPR (4.85) were 40% (6/15) and 20% (6/30), respectively. Relative risks (95% CI) of later PE were 10.0 (3.82-26.4; 27% [9/33] vs. 2.7% [6/221]) and 4.98 (1.91-13.0; 20% [6/30] vs. 4.0% [9/224]) for NCR-positive and FPR-positive women, respectively. Cut-offs suggested by ROC gave NCR (86.6) sensitivity and PPV of 87% (13/15) and 17% (13/79), and FPR (8.8) values of 40% (6/15) and 40% (6/15), respectively. Thus, 2nd trimester NCR was superior to FPR for PE prediction. - Suppression of iASPP-dependent aggressiveness in cervical cancer through reversal of methylation silencing of microRNA-124

英語, 研究論文(学術雑誌), Derepression of wild-type p53 by suppressing its negative inhibitor iASPP (Inhibitor of apoptosis-stimulating protein of p53) represents a potential therapeutic option for cervical cancer (CC). Here, we reported a novel functional significance of iASPP upregulation in cervical tumorigenesis: iASPP acts as a key promoter of CC cell proliferation, epithelial-mesenchymal transition, invasion and cancer stemness, by interacting with p53 to suppress p53-mediated transcription of target genes and reducing p53-responsive microRNA-34a levels. Moreover, we demonstrate that miR-124, directly targeting iASPP, reduces expression of iASPP and attenuates CC cell growth and invasiveness. Low miR-124 expression is inversely correlated with increased expression of iASPP mRNA in CC tissues. In a cohort of 40 patients with CC, the low miR-124 expression was correlated with poor 5-year overall survival (P = 0.0002) and shorter disease-free survival 5-year (P = 0006). Treatment with the DNA methyltransferase inhibitor Zebularine increases miR-124 expression and retards CC cell growth and invasion with minimal toxicity to normal cells. Even at a non-toxic concentration, Zebularine was effective in suppressing CC cell invasion and migration. Altogether, the restoration of miR-124 reduces iASPP expression and leads to p53-dependent tumor suppression, suggesting a therapeutic strategy to treat iASPP-associated CC. - 妊娠高血圧腎症妊婦における尿中ポドサイトの量的ならびに質的変化

英語, 研究論文(学術雑誌), Background: In ovarian cancer (OC) cells, Snail was reported to induce the epithelial-to-mesenchymal transition (EMT), which is a critical step in OC metastasis. At present little is known about controlling Snail expression in OC cells by using specific microRNAs (miRNAs).
Methods: We first used a computational target prediction analysis to identify 6 candidate miRNAs that bind to the 3'-untranslated region (3'-UTR) region of the Snail mRNA. Among these miRNAs, two miRNAs (miR-137 and miR-34a) with a potential to regulate Snail were validated by quantitative real-time PCR, Western blot analysis, and Snail 3'- UTR reporter assays. We assessed the effects of miR-137 and miR-34a on EMT, invasion and sphere formation in OC cells. We also evaluated the expression of miR-137 and miR-34a in OC tissues and adjacent normal tissues and analyzed the relationship between their expression and patient survival.
Results: We report that OC tissues possess significantly decreased levels of miR-137 and miR-34a and increased expression of Snail when compared to their adjacent normal tissues, and lower miR-137 and miR-34a expression correlates with worse patient survival. Using luciferase constructs containing the 3'- UTR region of Snail mRNA combined with miRNA overexpression and mutagenesis, we identified miR-137 and miR-34a as direct suppressors of Snail in OC cells. The introduction of miR-137 and miR-34a resulted in the suppression of Snail at both the transcript and protein levels, and effectively suppressed the EMT phenotype and sphere formation of OC cells. However, the inhibition of miR-137 and miR-34a with antisense oligonucleotides promoted EMT and OC cell invasion. Moreover, ectopic expression of Snail significantly reversed the inhibitory effects of miR-137 and miR-34a on OC cell invasion and sphere formation.
Conclusions: These findings suggest that both miR-137 and miR-34a act as Snail suppressors to negatively regulate EMT, invasive and sphere-forming properties of OC cells. - Isolated gestational proteinuria preceding the diagnosis of preeclampsia - an observational study

英語, 研究論文(学術雑誌), Introduction. Some pregnant women develop significant proteinuria in the absence of hypertension. However, clinical significance of isolated gestational proteinuria (IGP) is not well understood. This study aimed to determine the prevalence of IGP in singleton pregnancies and the proportion of women with IGP who subsequently developed preeclampsia (IGP-PE) among all PE cases. Material and methods. This was an observational study of 6819 women with singleton pregnancies at 12 centers, including 938 women with at least once determination of protein-to-creatinine ratio (P/Cr). Significant proteinuria in pregnancy (SPIP) was defined as P/Cr (mg/mg) level >0.27. IGP was defined as SPIP in the absence of hypertension. Gestational hypertension (GH) preceding preeclampsia (GH-PE) was defined as preeclampsia (PE) in which GH preceded SPIP. Simultaneous PE (S-PE) was defined as PE in which both SPIP and hypertension occurred simultaneously. Results. IGP and PE were diagnosed in 130 (1.9%) and 158 (2.3%) of 6819 women, respectively. Of 130 women with IGP, 32 (25%) progressed to PE and accounted for 20% of all women with PE. Hence, women with IGP had a relative risk of 13.1 (95% CI; 9.2-18.5) for developing PE compared with those without IGP [25% (32/130) vs. 1.9% (126/6689)]. At diagnosis of SPIP, P/Cr levels already exceeded 1.0 more often in women with S-PE than in those with IGP-PE [67% (33/49) vs. 44% (14/32), respectively, p = 0.031]. Conclusions. IGP is a risk factor for PE, and IGP-PE accounts for a considerable proportion (20%) of all PE. - Fetal cell-free DNA fraction in maternal plasma is affected by fetal trisomy

英語, 研究論文(学術雑誌), The purpose of this noninvasive prenatal testing (NIPT) study was to compare the fetal fraction of singleton gestations by gestational age, maternal characteristics and chromosome-specific aneuploidies as indicated by z-scores. This study was a multicenter prospective cohort study. Test data were collected from women who underwent NIPT by the massively parallel sequencing method. We used sequencing-based fetal fraction calculations in which we estimated fetal DNA fraction by simply counting the number of reads aligned within specific autosomal regions and applying a weighting scheme derived from a multivariate model. Relationships between fetal fractions and gestational age, maternal weight and height, and z-scores for chromosomes 21, 18 and 13 were assessed. A total of 7740 pregnant women enrolled in the study, of which 6993 met the study criteria. As expected, fetal fraction was inversely correlated with maternal weight (P<0.001). The median fetal fraction of samples with euploid result (n=6850) and trisomy 21 (n=70) were 13.7% and 13.6%, respectively. In contrast, the median fetal fraction values for samples with trisomies 18 (n=35) and 13 (n=9) were 11.0% and 8.0%, respectively. The fetal fraction of samples with trisomy 21 NIPT result is comparable to that of samples with euploid result. However, the fetal fractions of samples with trisomies 13 and 18 are significantly lower compared with that of euploid result. We conclude that it may make detecting these two trisomies more challenging. - 妊婦における「抗リン脂質抗体症候群」と「抗リン脂質抗体陽性」の周産期予後の違い

英語, 研究論文(学術雑誌), A woman with twin pregnancy had a gradual decline in anti-thrombin (AT) activity from 72% at gestational week (GW) 29(-3/7), to 53% at GW31(-2/7), and to 41% at GW32(-2/7), at which time hypertension (148/90 mmHg) and proteinuria (protein-to-creatinine ratio [P/Cr], 0.79 mg/mg) developed in the presence of normal platelet count (159 x 10(9)/L) and serum aspartate aminotransferase/lactate dehydrogenase (22/164 IU/L). AT product was given three times to maintain AT activity >50% and blood pressure was maintained below 155/95 mmHg with no treatment, but generalized edema with a weekly weight gain of 4.9 kg and increased proteinuria (to P/Cr, 7.6 mg/mg) required cesarean section at GW33(-3/7). This case highlights the occurrence of pregnancy-induced AT deficiency alone in the absence of any other abnormality, including hypertension, proteinuria, or thrombocytopenia. Measurement of AT activity was considered helpful for determination of the appropriate time for delivery in this patient. - Occult fetomaternal hemorrhage in women with pathological placenta with respect to permeability

英語, 研究論文(学術雑誌), Aim: Women with pre-eclampsia (PE), placenta previa (PP), placental abruption (PA), and placental mesenchymal dysplasia (PMD) have been described as having placental permeability dysfunction. This study was performed to determine whether occult fetomaternal hemorrhage (FMH) is common in women with such complications and in women with non-reassuring fetal status.
Methods: Forty-one antenatal and 39 postnatal blood samples were obtained from 46 women, including 11 with placental permeability dysfunction (5, 3, 2, and 1 with PE, PP, PA, and PMD, respectively) and 35 controls without such complications. To estimate the amount of fetal red blood cells, flow cytometry was performed using the fetal cell count system with two antibodies against fetal hemoglobin and carbonic anhydrase and the beta-gamma system with two monoclonal antibodies against hemoglobin beta-chain and hemoglobin gamma-chain. A diagnosis of FMH was made when the fraction size of the isolated cell population on scatter plots expressing fetal hemoglobin alone or hemoglobin gamma-chain alone accounted for >= 0.02% of the total cell population on scatter plots.
Results: FMH was identified in five women, including one each with PE, PA, PP, PMD, and no complications. Thus, the prevalence rate of FMH was significantly higher in women with complications than in controls (36% [4/11] vs 2.9% [1/35], respectively, P = 0.009). The FMH occurrence rate did not differ between women with and without non-reassuring fetal status (7.7% [1/13] vs 12% [4/33], respectively, P = 1.000).
Conclusion: The risk of fetal red blood cells trafficking into the maternal circulation may be increased in women complicated with PE, PA, PP, and PMD. - 妊娠初期の血小板凝集塊形成についての検討

英語, 研究論文(学術雑誌), Overexpression of IQGAP1 and microRNA (miRNA) dysregulation are frequent in human tumors, but little is known about the role of IQGAP1 and its relationship to miRNA in endometrial carcinogenesis. We demonstrate that IQGAP1 activates the epithelial-mesenchymal transition (EMT) program and that miR-124 directly represses IQGAP1 expression in endometrial cancer (EC) cells. The overexpression of IQGAP1 stimulates EMT features and enhances migration, invasion and proliferation of EC cells, whereas knocking down IQGAP1 expression reverses EMT and inhibits these malignant properties. Using miRNA microarray profiling, we identified 29 miRNAs (let-7b, let-7f, miR-10b, miR-15b, miR-23a, miR-24, miR-25, miR-27a, miR-29b, miR-30a-5p, miR-34a, miR-124, miR-127, miR-130b, miR-148a, miR-155, miR-191*, miR-194, miR-224, miR-362, miR-409-3p, miR-422b, miR-424, miR-453, miR-497, miR-518d, miR-518f*, miR-526a and miR-656) that are significantly down-regulated in an in vitro-selected highly invasive derivative cell line (HEC-50-HI) relative to the parental HEC-50 cells. We further identified miR-124 as a direct regulator of IQGAP1 in EC cells. Enforced expression of miR-124 suppresses EC cell invasion and proliferation. The expression of IQGAP1 mRNA was significantly elevated in EC tissues, while the expression of miR-124 was decreased. The downregulation of miR-124 correlates with a poor survival outcome for patients with EC. Treating EC cells with the demethylating agent 5-aza-2'-deoxycytidine increased miR-124 expression and down-regulated IQGAP1 levels. Our data suggest that IQGAP1 promotes EMT, migration and invasion of EC cells. MiR-124, a novel tumor suppressor miRNA that is epigenetically silenced in EC, can reverse EMT and the invasive properties, by attenuating the expression of the IQGAP1 oncogene. - Alteration of podocyte phenotype in the urine of women with preeclampsia

英語, 研究論文(学術雑誌), Podocyte injury has been suggested to induce phenotypic alteration of glomerular podocytes and accelerate the detachment of podocytes from the glomeruli resulting in podocyturia. However, it is not clear whether podocyte phenotypic alteration occurs in the urine of women with preeclampsia (PE). Seventy-seven and 116 pelleted urine samples from 38 and 18 women at various stages of normal and PE pregnancies, respectively underwent quantitative analysis of podocyte-specific or associated protein mRNA expression, including podocin, nephrin, and synaptopodin using RT-PCR. Significant proteinuria in pregnancy (SPIP) is defined as protein: creatinine ratio (P/Cr, mg/mg) >= 0.27 in the urine supernatant. All three urine-pellet mRNAs expression levels were significantly positively correlated with P/Cr levels, suggesting that podocyturia increased with proteinuria. The podocin: nephrin mRNA ratio (PNR) and synaptopodin: nephrin mRNA ratio (SNR) increased significantly with increasing P/Cr, while the podocin: synaptopodin mRNA ratio (PSR) did not change significantly according to P/Cr, resulting in significantly higher PNR and SNR, but not PSR levels, in urine from PE women with than without SPIP. The PNR, SNR, and PSR in urine from PE women before onset of SPIP were comparable to those from controls. Thus, nephrin mRNA expression was reduced in the podocytes recovered from PE women. - Survey of prenatal testing for genetic disorders in Japan: Recent report

英語, 研究論文(学術雑誌), AimIn order to investigate the current status of prenatal testing for genetic disorders, we conducted a multicenter retrospective questionnaire survey.
MethodsThe questionnaire was sent to 105 facilities with genetic counseling systems. The questionnaire consisted of two parts: (i) the number of prenatal tests conducted for genetic disorders from January 2010 to December 2012, whether the laboratory was combined with the counseling facility or separate, the sampling procedure method, the testing results, and the outcomes of the affected fetus in addition to treatment; and (ii) a survey of personal comments regarding prenatal testing for genetic disorders.
ResultsWe received responses from 69 of the 105 facilities (65.7%), and genetic testing was performed at 26 of these facilities. Nucleic acid sequential testing was performed on 45 disorders and 252 cases during a three-year period. There were 67 cases of affected fetuses. Six cases continued pregnancy and were treated. The comment survey highlighted difficulties in locating a laboratory to assess prenatal samples, as well as inadequate counseling and preparation for genetic disorders.
ConclusionsOur study revealed that a number of prenatal testing for genetic disorders are conducted in Japan; however, it is difficult for counselors to locate a laboratory capable of testing for specific genetic disorders. Inadequate counseling and healthcare providers' lack of knowledge is a current problem. A well-established system of prenatal testing for genetic disorders and the further education of general physicians is required. - Criteria for radiologic diagnosis of hypochondroplasia in neonates

英語, 研究論文(学術雑誌), A radiologic diagnosis of hypochondroplasia is hampered by the absence of age-dependent radiologic criteria, particularly in the neonatal period.
To establish radiologic criteria and scoring system for identifying neonates with fibroblast growth factor receptor 3 (FGFR3)-associated hypochondroplasia.
This retrospective study included 7 hypochondroplastic neonates and 30 controls. All subjects underwent radiologic examination within 28 days after birth. We evaluated parameters reflecting the presence of (1) short ilia, (2) squared ilia, (3) short greater sciatic notch, (4) horizontal acetabula, (5) short femora, (6) broad femora, (7) metaphyseal flaring, (8) lumbosacral interpedicular distance narrowing and (9) ovoid radiolucency of the proximal femora.
Only parameters 1, 3, 4, 5 and 6 were statistically different between the two groups. Parameters 3, 5 and 6 did not overlap between the groups, while parameters 1 and 4 did. Based on these results, we propose a scoring system for hypochondroplasia. Two major criteria (parameters 3 and 6) were assigned scores of 2, whereas 4 minor criteria (parameters 1, 4, 5 and 9) were assigned scores of 1. All neonates with hypochondroplasia in our material scored a parts per thousand yen6.
Our set of diagnostic radiologic criteria might be useful for early identification of hypochondroplastic neonates. - Influenza 2014-2015 among pregnant Japanese women: primiparous vs multiparous women

英語, 研究論文(学術雑誌), This study was performed to determine whether multiparous pregnant women are prone to influenza. A questionnaire survey was conducted at 19 centres located throughout Japan, targeting all 6,694 postpartum women within 7 days after birth before leaving the hospital. All women gave birth during the study period between March 1, 2015, and July 31, 2015. Data regarding vaccination and influenza infection in or after October 2014, age, previous experience of childbirth, and number and ages of cohabitants were collected. Seventy-eight percent (n = 51,97) of women given questionnaires responded. Of these, 2,661 (51 %) and 364 (7.0 %) women reported having been vaccinated and having contracted influenza respectively. Multiparous women had a higher risk of influenza regardless of vaccination status (8.9 % [121/1362] vs 5.7 % [74/1299], relative risk [95 % confidence interval], 1.80 [1.36 to 2.38] for vaccinated and 9.3 % [112/1198] vs 4.3 % [57/1328], 2.18 [1.60 to 2.97] for unvaccinated women) compared to primiparous women. The risk of influenza increased with increasing number of cohabitants: 4.8 % (100/2089), 7.5 %, (121/1618), 9.0 %, (71/785), and 10.4 % (58/557) for women with 1, 2, 3, and a parts per thousand yen4 cohabitants respectively. Family size is a risk factor for influenza infection in pregnancy. - Platelet reactivity in twin pregnancies

英語, 研究論文(学術雑誌), Background: Gestational thrombocytopenia is more likely to occur in twin than singleton pregnancies. However, it is unclear whether platelets are more reactive in twin than singleton pregnancies.
Methods: Changes in spontaneous platelet aggregation and concomitant fall in platelet count were examined over 90 min after blood sampling in 171 and 52 citrated whole blood (CWB) samples from 59 and 17 women with singleton and twin pregnancies, respectively. Soluble P-selectin (sP-selectin) levels in the plasma were also determined.
Results: CWB 60 min after blood sampling during 2nd trimester exhibited significantly larger numbers of platelet aggregates (1297 +/- 1600 vs. 497 +/- 432/mu l, P = 0.040) concomitant with significantly greater net decrease in platelet count (152 +/- 55 vs. 115 +/- 45 x 10(9)/mu l, P = 0.036) in twin than singleton pregnancies, respectively. This was followed by significantly lower 3rd trimester platelet count (181 +/- 43 vs. 229 +/- 62 x 10(9)/l, P = 0.009) with significantly greater mean platelet volume (8.0 +/- 1.2 vs. 7.1 +/- 1.1 fl, P = 0.021) in twin than singleton pregnancies, respectively. The 3rd trimester sP-selectin per platelet was significantly higher in twin than singleton pregnancies.
Conclusions: Platelets were more reactive in the 2nd trimester of twin than singleton pregnancies. This enhanced platelet reactivity may explain the decreased platelet count in the 3rd trimester of twin pregnancy. (C) 2016 Elsevier Ltd.

英語, 研究論文(学術雑誌), Objective: This study was performed to determine how often Japanese women diagnosed as normoglycemic on first-trimester 75-g glucose tolerance test (75gGTT) later develop gestational diabetes mellitus (GDM).
Material and methods: Sixty-two women with random plasma glucose (PG) level >= 105 mg/dL during the first trimester and subsequent first-trimester diagnosis of normoglycemia with 75gGTT underwent 50-g glucose challenge test (50gGCT) during the second trimester. Twenty-one with a positive 50gGCT result (60-m PG >= 140 mg/dL) underwent second-trimester 75gGTT. First-trimester random PG levels and 75gGTT results were compared between 21 and 41 women with positive and negative 50gGCT results, respectively. Changes in immunoreactive insulin (IRI) associated with 75gGTT were determined simultaneously.
Results: All 21 women with a positive 50gGCT result showed normoglycemia on second-trimester 75gGTT. Thus, none of the 62 women developed GDM. Insulin resistance increased significantly in the 21 women with 75gGTT during the first and second trimesters, as indicated by increases in homeostasis model assessment for insulin resistance (HOMA-IR) and homeostasis model assessment for beta-cell function (HOMA-beta) with no significant changes in preload or afterload PG levels. Neither random PG levels (116 +/- 12 vs. 116 +/- 12 mg/dL, respectively) nor 75gGTT results (86 +/- 6 vs. 84 +/- 5 mg/dL for 0-minute [0-m] PG level, 130 +/- 28 vs. 131 +/- 25 mg/dL for 60-m PG, and 111 +/- 19 vs. 118 +/- 18 mg/dL for 120-m PG, respectively) during the first trimester differed significantly between the 41 and 21 women with negative and positive second-trimester 50gGCT results, respectively.
Conclusion: Although insulin resistance increased in the second trimester, risk of developing GDM was < 1/62 among Japanese women in whom hyperglycemia was excluded with first-trimester GTT.

BMJ Case Reports, 2016, BMJ Publishing Group, 2016年, [査読有り]
英語, 研究論文(学術雑誌), We report a pregnant woman who was monitored by echocardiography and determination of blood variables, including components of the renin-angiotensin- aldosterone system (RAAS), cardiac biomarkers and soluble fms-like tyrosine kinase-1 (sFlt-1), during and after the development of Ballantyne syndrome. Generalised maternal oedema with dyspnoea following fetal and placental hydrops necessitated a caesarean section at 33 weeks of gestation. Changes in blood variables and simultaneous echocardiography changes indicated acutely enhanced RAAS and hyperdynamic left ventricular function in response to excessive volume overload (as evidenced by brain-type natriuretic peptide level of 523 pg/mL) in the absence of increased systemic vascular resistance. Elevated sFlt-1 (15 600 pg/mL) and human chorionic gonadotrophin (404 000 IU/L) levels were also noted. The increased plasma aldosterone concentration (2070 pg/mL) may have been responsible for the increase in circulating plasma volume, and the increased sFlt-1 level was responsible for generalised maternal oedema. It remains unclear which factor(s) triggered RAAS activation. - Feasibility of nephrinuria as a screening tool for the risk of pre-eclampsia: prospective observational study

英語, 研究論文(学術雑誌), Objectives: To investigate the possibility of nephrinuria as a screening tool for the risk of pre-eclampsia (PE).
Design: Prospective observational study.
Setting: A single university hospital. Changes in urinary nephrin: creatinine ratio (NCR, ng/mg) and protein: creatinine ratio (PCR, mg/mg) in pregnancy were determined. Significant proteinuria in pregnancy (SPIP) was defined as PCR> 0.27. PE was diagnosed in women with both SPIP and hypertension.
Participants: 89 pregnant women in whom neither hypertension nor SPIP was present at enrolment, providing 31, 125 and 93 random urine samples during first, second and third trimesters, respectively.
Results: PE developed in 14 of the 89 women. NCR increased with increasing PCR in 14 women with PE (correlation coefficient, 0.862; p<0.0001). In contrast, NCR did not change significantly despite significant increases in PCR in 75 women with normotensive pregnancies defined as neither SPIP nor hypertension, indicating that there was little increase in nephrinuria over the physiological range of proteinuria in pregnancy. Relative risk of later development of PE among asymptomatic second and third trimester women with NCR (ng/mg) > 122 (95th centile value for 75 women with normotensive pregnancies) was 5.93 (95% CI 2.59 to 13.6; 60% (6/10) vs 10% (8/79)) and 13.5 (95% CI 3.31 to 55.0; 75% (6/8) vs 5.5% (2/36)), respectively, compared with women with NCR <= 122 at that time.
Conclusions: Nephrinuria was unlikely to increase in normal pregnancy. A certain NCR cut-off may efficiently differentiate women at higher risk of PE. - 日本遺伝カウンセリング学会, 出生前遺伝カウンセリング検討委員会.出生前遺伝カウンセリングに関する提言(解説)

日本語, 研究論文(学術雑誌), 2014年3月時点で、日本医学会の認可を得ていた非侵襲的出生前遺伝学的検査(NIPT)コンソーシアム参加38施設の施設責任者および遺伝カウンセリング担当者を対象に、現場の遺伝カウンセリングの状況について質問紙調査を実施した。31施設の施設責任者と115名の遺伝カウンセリング担当者より回答が得られた。受診希望者数に対して十分に対応できていないと、9施設(30%)が回答した。NIPT希望者の特徴として、「遺伝に関する基礎知識が十分ではない」(64%)、「検査を受けると決めている」(23%)、「気軽に受検している」(19%)などがあげられた。双胎妊娠の検査適応や、性染色体や染色体微細欠損症候群への対象疾患の拡大については、慎重な意見が多く見られた。侵襲的確定検査、母体血清マーカー検査の実態把握システムが必要との回答が7割近くであった。遺伝学教育や出生前遺伝学的検査に関する知識普及、出生前遺伝学的検査の体制整備が必要であると考えられた。 - Urinary protein-to-creatinine ratio in pregnant women after dipstick testing: prospective observational study

英語, 研究論文(学術雑誌), Background: The dipstick test is widely used as a primary screening test for detection of significant proteinuria in pregnancy (SPIP). However, it often shows a false positive test result. This study was performed to determine which pregnant women should be recommended to undergo determination of urinary protein-to-creatinine ratio (mg/mg, P/Cr test) after dipstick test for confirmation of SPIP.
Methods: This was a multicenter, prospective, and observational study of 2212 urine specimens from 1033 pregnant women who underwent simultaneous dipstick and P/Cr tests in the same spot urine samples at least once. SPIP was defined as P/Cr > 0.27. Preeclampsia was diagnosed in women with both hypertension and SPIP.
Results: Preeclampsia, hypertension alone, and SPIP alone developed in 202 (20 %), 73 (7.1 %), and 120 (12 %) women, respectively. Creatinine concentration [Cr] varied greatly, ranging from 8.1 to 831 mg/dL in the 2212 urine samples. Rate of positive dipstick test results increased with increasing [Cr], while SPIP prevalence rate was lower in urine samples with higher [Cr], yielding higher false positive rates in samples with higher [Cr]. Postpartum urine samples had significantly lower [Cr] compared to those obtained antepartum (60 [8.7-297] vs. 100 [10-401] mg/dL, respectively). At the first P/Cr test among women with similar dipstick test results, the risk of having SPIP was consistently and significantly higher for hypertensive women than for normotensive women at any dipstick test result: 18 % (14/77) vs. 3.2 % (8/251), 47 % (26/55) vs. 8.7 % (37/425), 91 % (82/90) vs. 59 % (44/75) for negative/equivocal, 1+, and >= 2+ test results, respectively. The risk of SPIP was 16 % (9/55) for normotensive women when two successive antenatal urine samples showed a dipstick test result of 1 +.
Conclusions: For prediction of SPIP, the dipstick test was more likely to show a false positive result in concentrated urine samples with higher [Cr]. Hypertensive women with >= 1+ as well as normotensive women with >= 2+ on dipstick test should be advised to undergo the P/Cr test. - Long-term persistent fetomaternal hemorrhage.

英語, 研究論文(学術雑誌), AimTo determine intrapartum factors associated with neonatal encephalopathy leading to cerebral palsy (NE-CP).
MethodsA total of 70 NE-CP patients who fulfilled study criteria (cephalic singleton pregnancy with attempted vaginal delivery [AVD] at gestational week [GW] 36; intrapartum occurrence of non-reassuring fetal status without apparent cause following reassuring fetal status on admission; and development of NE-CP) were compared with 210 AVD controls who had 1- and 5-min Apgar score 8 matched for GW, maternal parity, and use of uterotonics. Suboptimal care was defined as delayed reaction due to misinterpretation of fetal heart rate (FHR) tracing, or inappropriate trial of instrumental delivery (TOID). Successful and failed TOID were defined as vaginal and cesarean delivery after TOID, respectively. The 210 controls were assumed not to have had suboptimal care.
ResultsThe rates of successful (34% vs 12%) and failed TOID (11% vs 0.0%), cesarean section (34% vs 14%), suboptimal care (57% vs 0.0%), pregnancy-induced hypertension (11% vs 2.4%), birthweight 3800 g (8.6% vs 1.9%), subgaleal hemorrhage (16% vs 0.0%) were significantly higher in NE-CP patients than in controls. Selection with the stepwise method and logistic regression analysis identified four independent risk factors for NE-CP: suboptimal intrapartum care (OR, 2.21; 95%CI: 1.99-2.47), cesarean section (OR, 1.19; 95%CI: 1.08-1.31), successful TOID (OR, 1.14; 95%CI: 1.03-1.25), and hypertension (OR, 1.20; 95%CI: 1.01-1.42).
ConclusionsTraining programs for improved interpretation of FHR tracing and appropriate TOID are required to prevent NE-CP among healthy and mature fetuses in Japan. - Prospective risk of stillbirth in women with placental mesenchymal dysplasia

英語, 研究論文(学術雑誌), AimThe aim of this study was to provide better counsel to pregnant women with suspected placental mesenchymal dysplasia (PMD) regarding the risks of preterm birth and intrauterine fetal death.
Material and MethodsWe reviewed the outcomes of 109 PMD pregnancies with gestational week (GW)24 abstracted from 63 reports in the English-language published reports, including two cases that we encountered recently. The prospective risk of stillbirth at GW N was defined as the number of women with stillbirth at GWN divided by the number of women giving birth at GWN.
ResultsA total of 32 (29.4%) women experienced stillbirth at a median GW of 31 (range, 24-38). Preterm birth (GW <37) occurred in 52 (67.5%) of the 77 live-born infants. Only 25 (22.9%) women had full-term (GW37) live-born infants. The prospective risks of stillbirth were 29.4% (32/109), 27.5% (25/91), 20.9% (14/67) and 13.0% (6/46) for women who reached GW 24(+0), 28(+0), 32(+0) and 36(+0) respectively.
ConclusionAs women with PMD are at markedly elevated risk of intrauterine fetal death, early admission to the hospital and intensive monitoring of fetal status should be considered, although whether this policy improves outcome has not been validated. - 36週で陣痛発来し、緊急血小板輸血後に分娩となったITP合併妊娠の一例

英語, 研究論文(学術雑誌), Epigenetic modifications are thought to serve as a memory of exposure to in utero environments. However, few human studies have investigated the associations between maternal nutritional conditions during pregnancy and epigenetic alterations in offspring. In this study, we report genome-wide methylation profiles for 33 postpartum placentas from pregnancies of normal and foetal growth restriction with various extents of maternal gestational weight gain. Epigenetic alterations accumulate in the placenta under adverse in utero environments, as shown by application of Smirnov-Grubbs' outlier test. Moreover, hypermethylation occurs frequently at the promoter regions of transcriptional regulator genes, including polycomb targets and zinc-finger genes, as shown by annotations of the genomic and functional features of loci with altered DNA methylation. Aberrant epigenetic modifications at such developmental regulator loci, if occurring in foetuses as well, will elevate the risk of developing various diseases, including metabolic and mental disorders, later in life. - Role of the Atg9a gene in intrauterine growth and survival of fetal mice

英語, 研究論文(学術雑誌), Autophagy is activated by environment unfavorable for survival and requires Atg9a protein. Mice heterozygous for p57(KiP2), devoid of the imprinted paternal allele (p57(KiP2+/-)), are known to develop hypertension during pregnancy. To determine whether fetal Atg9a is involved in the intrauterine survival and growth of fetal mice, this study was performed on Atg9a heterozygous (Atg9a(+/-)) pregnant mice with and without p57(KiP2+/-). The pregnant mice heterozygous for both knockout alleles of Atg9a and p57(KiP2) (Atg9a(+/-)/p57(KiP2+/-)), but not those heterozygous for Atg9a alone, developed hypertension during pregnancy. Placental expression of Atg9a mRNA was significantly decreased in the Atg9a(-/-) mice compared to Atg9a(+/-) or Atg9a(+/+) mice. The Atg9a(-/-) fetal mice exhibited significantly retarded growth and were more likely to die in utero compared to Atg9a(+/+) and Atg9a(+/-) fetal mice. Growth retardation was observed in the presence of maternal hypertension in Atg9a(-/-) fetal mice. These results suggest that Atg9a(-/-) fetal mice from pregnant dams heterozygous for both knockout alleles of Atg9a and p57(KiP2) are more susceptible to hypertensive stress than fetuses with intact autophagic machinery.

英語, 研究論文(学術雑誌), Although mutational inactivation of p53 is found in 50% of all human tumors, a subset of tumors display defective p53 function, but retain wild-type (WT) p53. Here, direct and indirect mechanisms leading to the loss of WT p53 activities are discussed. We summarize the oncogenic roles of iASPP, an inhibitor of WT p53, in promoting proliferation, invasion, drug or radiation-resistance and metastasis. From the therapeutic view, we highlight promising perspectives of microRNA-124, peptide and small molecules that reduce or block iASPP for the treatment of cancer. High iASPP expression enhances proliferation, aggressive behavior, the resistance to radiation/chemotherapy and correlates with poor prognosis in a range of human tumors. Overexpression of iASPP accelerates tumorigenesis and invasion through p53-dependent and p53-independent mechanisms. MicroRNA-124 directly targets iASPP and represses the growth and invasiveness of cancer cells. The disruption of iASPP-p53 interaction by a p53-derived peptide A34 restores p53 function in cancer cells. The inhibition of iASPP phosphorylation with small molecules induces p53-dependent apoptosis and growth suppression. The mechanisms underlying aberrant expression of iASPP in human tumors should be further investigated. Reactivating WT p53 functions by targeting its novel inhibitor iASPP holds promise for potential therapeutic interventions in the treatment of WT p53-containing tumors. - Platelet aggregation in citrated whole blood of the first trimester of pregnancy

英語, 研究論文(学術雑誌), Background: It was recently suggested that platelet reactivity is reduced in early pregnancy. This study was performed to determine whether the citrated whole blood from 33 pregnant women in their first trimester showed spontaneous platelet aggregation and whether it differed in extent from that of 11 non-pregnant women.
Methods: The platelet count and number of platelet aggregates (PA) were serially determined in the same citrated whole blood specimens at 15, 30, 45, 60, 75, and 90 min after blood sampling using a hematology analyzer.
Results: The number of PA increased significantly at 30 min and thereafter in both groups, but was consistently lower for pregnant than non-pregnant women over the 90-min observation period. The platelet count decreased significantly in a time-dependent manner in both groups, but was significantly lower at 30 and 90 min for nonpregnant than pregnant women. The number of PA showed a significant positive correlation with net decrease in platelet count for both pregnant and non-pregnant women. PA counts were also significantly positively correlated with the mean platelet volume.
Conclusion: Platelet reactivity monitored by the increase in number of PA and the fall in platelet count was reduced in early pregnancy compared with non-pregnant healthy controls. (C) 2015 Elsevier B.V. All rights reserved. - 妊娠高血圧症候群 最近の話題 妊娠蛋白尿とアンチトロンビン活性低下

英語, 研究論文(学術雑誌), This literature review was conducted to provide better counsel to pregnant women who erroneously took angiotensin receptor blockers (ARBs) during the second and/or third trimesters regarding infant outcomes. Information was available on 83 fetuses in 34 literature reports, including one that we encountered recently. Fourteen pregnancies were terminated, and six were unknown regarding status of amniotic fluid volume (AFV). Fifty-eight and five fetuses did and did not show oligohydramnios, respectively, after being exposed to ARBs. Of the 58 fetuses that presented with oligohydramnios, 57 were exposed to ARBs at gestational week (GW). 20, and 19 exhibited resolution of oligohydramnios 1-6 weeks after cessation of ARBs. The 24 mothers without oligohydramnios at delivery ceased taking ARBs earlier (GW of 26.8 +/- 5.1 vs. 31.8 +/- 4.0, respectively, P=0.000) and had longer duration of gestation after cessation of ARBs (8.4 +/- 5.2 vs. 0.7 +/- 2.3 weeks, respectively, P=0.000). The mothers without oligohydramnios also had better outcomes in terms of favorable infant outcomes (63% (15/24) vs. 15% (6/39), respectively, P=0.000) and infant mortality rates (13% (3/24) vs. 56% (22/39), respectively, P=0.001) than the 39 with oligohydramnios. Thus, a favorable outcome may be feasible if the fetuses are not indicated for prompt delivery at presentation and exhibit normal AFV or resolution of oligohydramnios after cessation of ARBs. Although the prevalence rate of oligohydramnios was high in this study, it may have been due to publication bias. A prospective study suggested a lower prevalence rate than that reported in the present study. - Protein S deficiency present in a pregnant woman with dyspnea, abdominal pains, restlessness, agitation and hypofibrinogenemia.

英語, 研究論文(学術雑誌), This questionnaire survey was conducted at 11 hospitals in Japan to determine vaccination coverage against seasonal influenza and the prevalence rate of influenza among pregnant Japanese women. Of 2,808 postpartum women who gave birth at the 11 hospitals during the study period from March 1, 2014, to July 31, 2014, 1,713 (61 %) participated in this study and 876 (51 %) reported having received vaccination against influenza in or after October 2013. Women aged < 25 years had a significantly lower vaccination rate than those aged a parts per thousand yen25 years (31 % vs. 53 %, respectively; p = 0.0000). Eighty-seven (5.1 %) and 1,626 (94.9 %) women did and did not contract influenza, respectively. Although prior birth did not affect overall vaccination coverage (50 % for primiparous vs. 53 % for multiparous), multiparous women had a significantly higher rate of contracting influenza than primiparous women, irrespective of vaccination status (5.6 % vs. 2.2 % [p = 0.0216] and 9.7 % vs. 3.5 % [p = 0.0003] for women with and without vaccination, respectively). The 2013-2014 vaccination program significantly reduced the influenza infection rate by 35 % (3.9 % vs. 6.3 % for women with and without vaccination, respectively; p = 0.0272). Seventy-two (83 %) of the 87 women took antiviral agents for the treatment of influenza and two (2.3 %) required hospitalization. These results suggested that pregnant Japanese women had a high level of concern regarding seasonal influenza. However, campaigns targeting young pregnant Japanese women, as well as multiparous women, for vaccination are needed in order to further reduce the incidence of influenza among pregnant Japanese women. - Fibrinogen levels in the late stage of twin pregnancy.

英語, 研究論文(学術雑誌), BackgroundThere is conflicting information regarding the risk of gestational diabetes mellitus in twin pregnancies. This study was conducted to determine whether the risk of gestational diabetes mellitus is higher in pregnant Japanese women with twin versus singleton pregnancy.
MethodsThe prevalence of gestational diabetes mellitus was studied in two different populations: 144589 women registered with the Japan Society of Obstetrics and Gynecology (JSOG cohort) over 3years between 2007 and 2009 in which patient selection bias was unavoidable; and 430 Japanese women who gave birth at a single centre over 5years between 2008 and 2012 (single-centre cohort), consisting of 86 women with twins and 344 women with singletons matched for maternal age and prepregnancy body mass index. The gestational diabetes mellitus was diagnosed on the basis of the previous criteria in the JSOG cohort. The gestational diabetes mellitus was screened in a stepwise method and diagnosed on the basis of the new criteria in the single-centre cohort.
ResultsIn the single-centre cohort, neither frequency of random glucose level 105mg/dL in the first trimester [9.0% (31/344) vs 5.8% (5/86)], positive result (140mg/dL) on 50g glucose challenge test in the second trimester [26.5% (90/339) vs 26.7% (23/86)], nor women diagnosed with GDM [8.4% (29/344) vs 9.3% (8/86)] differed between the two groups. The prevalence of hyperglycaemia was higher in singleton than in twin pregnancies in the JSOG cohort (2.6% vs 1.8%, p<0.001).
ConclusionsThe risk of gestational diabetes mellitus may be similar between Japanese women with singleton and twin pregnancies. Difference in the risk of hyperglycaemia in the JSOG cohort may have been due to selection bias.

© 2014 John Wiley & Sons, Ltd. Objective: To report the 1-year experience of a nationwide demonstration project to introduce noninvasive prenatal testing of aneuploidy from maternal plasma and discuss how to implement this program in Japan. Methods: The test was conducted to detect aneuploidy in high-risk pregnant women with adequate genetic counseling. The clinical data, test results, and pregnancy outcomes were recorded. Results: Of the 7740 women tested, 142 (1.8%) had positive results, 7594 (98.1%) had negative results, and four (0.1%) had results that were not reportable. Of the 142 women who tested positive, 13 cases resulted in intrauterine fetal death, and three cases refused to undergo the invasive procedure. Of the 126 positive cases confirmed on karyotyping, a normal karyotype was observed for trisomy 21 in three cases, trisomy 18 in eight cases, and trisomy 13 in two cases. In the follow-up study of the negative cases (n=1638), only one false-negative case of trisomy 18 was detected. Conclusions: We described our nationwide 1-year experience with noninvasive prenatal genetic testing. It is expected that the present data will stimulate a debate regarding prenatal genetic testing and hopefully lead to improvements in the perinatal care system with respect to genetic counseling in Japan. - A Case of Prenatal Presentation with Double Aortic Arch.

英語, 研究論文(学術雑誌), AimThe aim of this study was to determine whether antenatal decline in antithrombin (AT) activity occurs frequently and precedes the development of perinatal liver dysfunction in women with triplet pregnancies.
Material and MethodsA retrospective observational study was conducted on all women who gave birth to triplets at gestational week 22 at a single centre during a study period from January 2001 to March 2013. The following eight blood parameters were monitored weekly during the last 5 weeks of pregnancy and postpartum: AT activity, platelet count, fibrinogen, D-dimer, aspartate aminotransferase (AST), lactate dehydrogenase (LDH), uric acid and creatinine. Pregnancy-induced AT deficiency (PIATD) and gestational thrombocytopenia were defined as antenatal AT activity <70% of normal level and antenatal platelet count <150x10(9)/L, respectively. Liver dysfunction was defined as AST >40 IU/L. LDH elevation was defined as LDH >450 IU/L.
ResultsSixteen women were eligible for this study. All variables except LDH exhibited significant changes antenatally: AT activity, platelet count and fibrinogen decreased, while D-dimer, AST, urate and creatinine increased. LDH increased significantly postpartum. PIATD, gestational thrombocytopenia, perinatal liver dysfunction, and LDH elevation occurred in eight, seven, six, and eight women, respectively. Liver dysfunction was preceded by PIATD alone in three, by both PIATD and gestational thrombocytopenia in one and by gestational thrombocytopenia alone in none of the subjects. After delivery, laboratory abnormalities similar to HELLP syndrome were seen in three women exclusively in the presence of PIATD.
ConclusionsReduced AT activity was likely to precede perinatal liver dysfunction in women with triplets. - Autophagy in the placenta of women with hypertensive disorders in pregnancy

英語, 研究論文(学術雑誌), Introduction: Autophagy has not been studied extensively in the human placenta. This study was performed to determine whether autophagy is increased in the placentas of women with hypertensive disorders in pregnancy compared to normotensive pregnancies.
Methods: LC3-II and p62 protein expression were examined by quantitative Western blotting analysis in 40 placentas from women not experiencing labor pains. The 40 placentas were from 13, 8, and 19 women with preeclampsia, gestational hypertension, and normal pregnancy, respectively. Hypertensive disorders in pregnancy included preeclampsia and gestational hypertension.
Results: LC3-II expression was significantly increased, while that of p62 was significantly reduced in 21 placentas of women with hypertensive disorders compared to those with normal blood pressure irrespective of the presence or absence of fetal growth restriction (FGR). LC3-II expression was also significantly increased in 13 placentas of women with preeclampsia irrespective of the presence or absence of FGR.
Discussion: The results of this study suggested that autophagy is active in the placenta of hypertensive disorders even in the absence of FGR. (C) 2014 Elsevier Ltd. All rights reserved. - Peripartum cardiomyopathy in a woman with preeclampsia with twin pregnancy.

英語, 研究論文(学術雑誌), A 27-year-old nulliparous Japanese woman with twin pregnancy developed preeclampsia at gestational week (GW) 26. Cardiac function was checked regularly as women carrying twins with preeclampsia are expected to have increased risk of peripartum cardiomyopathy (PPCM). Although conventional parameters including blood pressure, proteinuria, platelet count and liver function did not indicate early delivery, gradual worsening of left ventricular ejection fraction (LVEF) to 44% and plasma brain-type natriuretic peptide level of 254 pg/mL suggested impending PPCM and a need for early delivery at GW 32. A nadir LVEF value of 35% on postpartum day (PPD) 3 followed by a value of 49% on PPD 32 was seen in this patient with PPCM. This case highlights the risk of PPCM among women with preeclampsia carrying twins and the role of pregnancy termination in the clinical course of PPCM. - Antenatal fibrinogen concentrations and postpartum haemorrhage

英語, 研究論文(学術雑誌), Background: It is unclear whether antenatal fibrinogen concentrations are associated with postpartum haemorrhage.
Methods: This retrospective study included 871 women with a singleton pregnancy but no known risk factors for postpartum haemorrhage, in whom fibrinogen concentration was measured within the 21 days before delivery. Correlation between antenatal fibrinogen concentrations and estimated blood loss was analysed. We tested the hypothesis that the risk of postpartum haemorrhage was higher in women with antenatal fibrinogen concentrations of <3.3 g/L. Postpartum haemorrhage was defined as an estimated blood loss >= 700 mL following vaginal delivery and >= 1000 mL following caesarean delivery.
Results: In women delivering vaginally (n = 337), estimated blood loss tended to increase with decreasing antenatal fibrinogen concentration (R = -0.107, P = 0.05), median fibrinogen concentration was significantly lower in 69 women with postpartum haemorrhage than in 268 women without postpartum haemorrhage (3.93 vs. 4.18 g/L, P = 0.025), and postpartum haemorrhage occurred significantly more often in women with fibrinogen concentrations <3.3 g/L than in those with concentrations >= 3.3 g/L (38% [11/29] vs. 19% [58/308], P = 0.018). In women undergoing caesarean delivery (n = 534), median fibrinogen concentration did not differ between those who experienced postpartum haemorrhage (n = 128) and those who did not (n = 406) (4.18 g/L vs. 4.07 g/L, P = 0.43). Antenatal fibrinogen concentrations of <3.3 g/L were not associated with higher rates of postpartum haemorrhage (26% [11/43] vs. 24% [117/491], P = 0.80).
Conclusions: Antenatal fibrinogen concentration <3.3 g/L may be a risk factor for postpartum haemorrhage among women following vaginal delivery. (C) 2014 Elsevier Ltd. All rights reserved. - 妊娠糖尿病の血糖管理と血糖自己測定法(SMBG) 血糖自己測定法(SMBG)は全ての妊娠糖尿病(GDM)妊婦に必要か?

英語, 研究論文(学術雑誌), As there is a risk of MTCT of HTLV-1, the HSGP HTLV-1 MTCT was organized in 2011. To determine how many pregnant women are infected with HTLV-1 in Hokkaido, which is the northernmost and the second largest island in Japan with a population of 5 467 000 and 39 392 newborns in 2011, the HSGP HTLV-1 MTCT asked all facilities that may care for pregnant women in Hokkaido in July 2013 to provide information on the number of pregnant women who underwent screening for anti-HTLV-1 antibody using particle agglutination or chemiluminescent enzyme immunoassay, and the numbers of those with positive, equivocal, and negative test results in the screening and confirmation tests using western blotting or PCR methods in 2012, respectively. A total of 111 facilities participated in this study and provided information on 33 617 pregnant women who underwent screening in 2012, corresponding to approximately 85% of all pregnant women who gave birth in Hokkaido in 2012. Of 81 candidates for a confirmation test because of positive (n = 77) or equivocal (n = 4) results on screening, 63 (78%) underwent the confirmation test and, finally, 34 (0.1%) and 33 563 (99.8%) women were judged to be HTLV-1 carriers and non-carriers, respectively. It was concluded that the prevalence rate of HTLV-1 carriers was low, one per 1000 pregnant women in Hokkaido. Approximately 40 infants are born yearly to mothers infected with HTLV-1 in Hokkaido. - 品胎妊娠における周産期肝機能障害についての検討 妊娠中のアンチトロンビン活性と血小板数との関連

英語, 研究論文(学術雑誌), Aim To determine whether macrosomic infants with a birthweight of 4.0kg or more have increased risk of cerebral palsy associated with neonatal encephalopathy (Enc-CP). Methods A retrospective review of 132 singleton infants with Enc-CP fulfilling all of the following criteria: born at gestational week (GW) 37 or more (n=126) or weighing 2.5kg or more at birth (n=116) in or after January 2009 in Japan; no identifiable causes of cerebral palsy other than antenatal or intrapartum hypoxia; and exhibition of neonatal encephalopathy. National statistics of Japan were used to determine the numbers of infants according to birthweight categories. Results Of the 116 infants with a birthweight of 2.5kg or more, 46 (39.7%), 49 (42.2%), 17 (14.7%) and four (3.4%) infants had birthweights of 2.5-2.99, 3.0-3.49, 3.5-3.99 and 4.0kg or more, respectively. Corresponding figures among Japanese infants born in 2009-2011 were 42.8%, 45.4%, 10.9% and 0.90%, respectively. Infants with a birthweight of 4.0kg or more had a relative risk (95% confidence interval) of Enc-CP of 3.89 (1.52-9.95) compared to those with a birthweight of 2.5-2.99kg. Conclusion Japanese infants with a birthweight of 4.0kg or more have increased risk of Enc-CP. - 子宮温存困難な癒着胎盤における子宮摘出術は1期的と2期的のどちらが適当か?

英語, 研究論文(学術雑誌), There has been only one case to date of pregnancy outcome after fundal transverse cesarean section (FTC). We report a pregnancy established after FTC. The FTC was performed at gestational week (GW) 24 in this patient's first pregnancy, but the uterus was preserved. Magnetic resonance imaging studies performed four times in her second pregnancy consistently showed part of the uterine fundus in which the muscle layer was interrupted. Concern regarding spontaneous uterine rupture in the absence of labor pains prompted us to interrupt her pregnancy at GW 31(+5), delivering a premature, but otherwise healthy female infant, weighing 1832g. The infant required transient intratracheal intubation for respiratory distress syndrome (for less than 1h), but had an otherwise uneventful clinical course. Two cases, including ours, suggest that successful pregnancy outcome is feasible at least in some women with uterine scarring due to FTC. - Do uterotonic drugs increase risk of abruptio placentae and eclampsia?

英語, 研究論文(学術雑誌), To determine whether the use of uterotonics, including oxytocin and prostaglandins, increases the risk of abruptio placentae and eclampsia.
A retrospective analysis was conducted among 260,174 Japanese women at term. Demographic characteristics were studied as possible candidates for risk factors of abruptio placentae and eclampsia using multivariate logistic regression analyses.
A total of 1,058 (0.41 %) and 147 (0.06 %) women developed abruptio placentae and eclampsia, respectively. Abruptio placentae and eclampsia occurred in 177 (0.29 %) and 42 (0.07 %) of the 61,857 women treated with uterotonics, respectively. Multivariate regression analyses indicated that uterotonics did not increase risk of developing either abruptio placentae or eclampsia. Primiparity [odds ratio (95 % confidence interval) 1.41 (1.24-1.60)], age a parts per thousand yen35 years [1.17 (1.03-1.33)], and presence of hypertension [2.42 (1.93-3.03)] were significant independent risk factors for abruptio placentae, while advancing gestation [0.67 (0.63-0.71)] decreased risk of abruptio placentae. Primiparity [odds ratio (95 % confidence interval) 4.06 (2.49-6.63)], age < 20 years [2.44 (1.07-5.58)], presence of hypertension [28.7 (20.5-40.1)], and advancing gestation [1.28 (1.11-1.47)] were significant independent risk factors for eclampsia.
The use of uterotonics did not increase the risk of abruptio placentae and eclampsia. - Seasonal variation in the prevalence of pregnancy-induced hypertension in Japanese women

英語, 研究論文(学術雑誌), AimWhether prevalence rate of pregnancy-induced hypertension (PIH), including gestational hypertension and pre-eclampsia, is lower for summer delivery than for winter delivery remains to be studied in Japanese women.
MethodsThe prevalence rate of PIH was retrospectively determined according to month of year at delivery and at conception in 301510 Japanese women who gave birth to singleton infants on or after gestational week 22 between 2005 and 2009.
ResultsThe overall prevalence of PIH was 4.6% (13848/301510). The prevalence rate of PIH, ranging 3.6-4.6% for women with deliveries in July-August was consistently lowest during the 5-year study period. The meanstandard deviation prevalence rate of 4.2 +/- 0.3% for delivery in July-August was significantly lower than those for any other month (January-February, 4.7 +/- 0.4%; March-April, 4.9 +/- 0.4%; May-June, 4.6 +/- 0.2%; September-October, 4.6 +/- 0.1%; and November-December, 4.6 +/- 0.2%). The prevalence rate of PIH was highest (4.9%) for women with conception in March and April and lowest (2.9%) for those with conception in November and December.
ConclusionThe prevalence rate of PIH was higher for delivery in winter and early spring and lowest for summer delivery among Japanese women. - 1絨毛膜2羊膜双胎における1児胎児発育不全に関する後方視的検討

英語, 研究論文(学術雑誌), Background: Japan experienced two rubella outbreaks in the past decade (2004 and 2012 - 2013), resulting in 10 and 20 infants with congenital rubella syndrome (CRS), respectively. This study was performed to determine whether the seronegative rate was lower in multiparous women than in primiparous women in Japan.
Methods: Hemagglutination inhibition (HI) test results during pregnancy were analyzed retrospectively in 11048 primiparous and 9315 multiparous women who gave birth at six hospitals in northern Japan in the 5-year study period (January 2008 through December 2012). Women with HI titer < 1: 8 were defined as susceptible to rubella.
Results: The seronegative rate was significantly lower in multiparous than primiparous women aged 30 - 31 years (2.3% [22/967] vs. 4.5% [66/1454], P = 0.0036), 36 - 37 years (3.4% [55/1601] vs. 5.7% [79/1389], P = 0.0030), and overall women (3.8% [350/9315] aged 34.7 +/- 5.2 vs. 5.4% [597/11048] for 33.2 +/- 5.9, P < 0.001). The susceptible fraction size did not differ largely according to hospital, ranging from 3.5% to 6.3%. Those for each year did not change markedly; 4.5% [150/3369], 5.2% [221/4268], 4.4% [195/4412], 4.6% [186/4056], and 4.6% [195/4258] for 2008, 2009, 2010, 2011, and 2012, respectively. Those for teenagers were consistently high: 22.7% [5/22], 20.7% [6/29], 20.6% [7/34], 13.0% [3/23], and 23.5% [4/17] for 2008, 2009, 2010, 2011, and 2012, respectively.
Conclusions: The seronegative rate was significantly lower in multiparous than primiparous women. However, Japanese rubella vaccination programs were insufficient to eliminate CRS. - Immune status among Japanese during nationwide rubella outbreak in Japan 2012-2013

英語, 研究論文(学術雑誌), As proposed criteria (Swansea criteria) for the diagnosis of acute fatty liver of pregnancy (AFLP) do not include antithrombin (AT) activity, diagnosis of AFLP may be delayed. The aim of this review is to underscore problems in the differential diagnosis of AFLP and the syndrome of hemolysis, elevated liver enzymes and low platelet counts (HELLP syndrome) and to facilitate prompt diagnosis of AFLP. Published works dealing with liver dysfunction in pregnancy, HELLP syndrome and AFLP were reviewed. AFLP and HELLP syndrome shared common clinical, laboratory, histological and genetic features, and differential diagnosis between them was often difficult. However, HELLP syndrome was likely to occur in patients with hypertension, but AFLP occurred often in the absence of hypertension. In addition, AFLP was exclusively associated with pregnancy-induced antithrombin deficiency (PIATD). Approximately 50% of patients with AFLP did not have thrombocytopenia at presentation. As the Swansea criteria for AFLP did not include PIATD, diagnosis of AFLP was delayed until manifestation of life-threatening complications; 60% of women were admitted to intensive care and 15% to a specialist liver unit. In conclusion, incorporation of AT activity of less than 65% into the diagnostic criteria for AFLP may facilitate suspicion and prompt diagnosis of AFLP, decrease uncertainty regarding the diagnosis of AFLP, and contribute to better investigation and understanding of the process leading to the development of liver dysfunction. - 胎児の循環機能評価 胎児心拍数波形5段階レベル分類におけるコンピューター判定システム(TRIUM)と医師のレベル判定一致率とそれに及ぼす要因(心拍数基線、基線細変動、一過性徐脈)の検証

英語, 研究論文(学術雑誌), AimThe aim of this study was to better characterize the nature of abruptio placentae (AP) with regard to the timing of onset.
Material and MethodsPrevalence and prospective risk of AP according to gestational week (GW) were determined among 293899 women who gave birth to singleton infants at and after GW 30. The prospective risk of AP at gestational week N was defined as the number of all women who experienced an AP at GW N divided by the number of all women who gave birth at GW N.
ResultsAP developed in 2649 (0.90%) women. The prevalence of AP (6.7% among women who gave birth at GW 30-33) sharply decreased with advancing GW at delivery to 0.9% for GW 37 and 0.1% for GW 42. The highest prospective risk of AP, 9 per 1000 women at GW 30, decreased linearly with advancing gestation to 1 per 1000 women at GW 42. AP accounted for 4.7% (1591/33725) of all preterm births at GW <37, while prevalence of AP was 0.41% (1058/260174) among term births. Preterm AP accounted for 60.1% (1591/2649) of all AP.
ConclusionOur figures indicate that AP is more common in preterm births than in term birth and may be helpful for better understanding the epidemiology of this condition. - Essential thrombocythemia as a risk factor for stillbirth

英語, 研究論文(学術雑誌), Introduction: The risk of abortion is known to be high in women with essential thrombocythemia (ET). However, a few studies have focused on the risk of stillbirth among fetuses reaching gestational age compatible with life.
Methods: Review of medical charts of pregnant women with ET who received cares at a single center between January 2003 and June 2013 and the English literature in which more than 20 pregnancies with ET were dealt with regarding outcomes. Outcomes were classified into three categories: spontaneous abortion or preterm delivery before GW 24, stillbirth at and after GW 24, and live birth (LB). Japan national statistics was used to estimate the risk of stillbirth among women with GW 22 or more.
Results: In all nine pregnancies in four women with ET at our hospital, two miscarriages, one stillbirth (intrauterine death at GW 35), and six LBs occurred. There were six reports in the English literature in which a total of 374 pregnancy outcomes were described: 110 miscarriages (29%), 14 stillbirths (3.7% of all 374 pregnancies and 5.3% of 264 pregnancies with GW >= 24), and 250 LBs (67%) occurred. Japan national statistics between 1995 and 2011 indicated that the risk of stillbirth was less than 0.50% among women with GW >= 22.
Conclusions: The risk of still birth was extremely high among women with ET. More intensified monitoring of fetal wellbeing may be required to improve outcome of pregnancy complicated with ET.

英語, 研究論文(学術雑誌), AimIt is not clear whether fetuses with Ebstein's anomaly are likely to show abnormalities on electronic fetal heart rate (FHR) monitoring during labor.
MethodsWe performed retrospective analysis of FHR monitoring results obtained between 2.5 and 0.5h prior to delivery in all of five fetuses prenatally diagnosed as having Ebstein's anomaly and born at our institution during the period between March 2005 and July 2011. All five mothers attempted to give birth vaginally. The results of FHR monitoring in 100 consecutive women with otherwise healthy singletons who attempted vaginal delivery were included as controls.
ResultsThe absence of FHR acceleration (4/5 [80%]), decreased baseline FHR variability (3/5 [60%]) and late deceleration (4/5 [80%]) were seen significantly more often in the five fetuses with Ebstein's anomaly than the 100 fetuses born to control women (6.0%, 6.0%, and 10%, respectively).
ConclusionFetuses with Ebstein's anomaly during labor were likely to exhibit absent acceleration, decreased baseline FHR variability and late deceleration compared to infants without cardiac structural anomalies. - Impact of planning of pregnancy in women with epilepsy on seizure control during pregnancy and on maternal and neonatal outcomes

英語, 研究論文(学術雑誌), Purpose: To investigate whether planning of pregnancy in women with epilepsy affects seizure control during pregnancy and to compare the maternal and neonatal outcomes in planned and unplanned pregnancies.
Methods: This was a retrospective cohort study of 153 pregnant women with epilepsy who were treated at the University of Tsukuba Hospital and Hokkaido University Hospital between 2003 and 2011. Twenty-one pregnancies were excluded due to insufficient data. Data of patients followed by neurologists during their planned pregnancies (planned-pregnancy group, n = 51) were compared to those of patients referred to neurologists after conception for managing epilepsy during pregnancy (unplanned-pregnancy group, n = 81). The treatment profile for epilepsy, seizure control, and maternal and neonatal outcomes in both groups were compared using Chi-square test or Fisher's exact test and Mann-Whitney U test.
Results: Compared to the unplanned-pregnancy group, the planned-pregnancy group showed a significantly greater proportion of patients receiving monotherapy with antiepileptic drugs (80% vs. 61%: planned vs. unplanned, P = 0.049) and those not requiring valproic acid (77% vs. 56%, P = 0.031). Furthermore, the frequency of epileptic seizures (16% vs. 35%, P = 0.018) and changes in antiepileptic drugs (24% vs. 41%, P = 0.042) were significantly lower in the planned-pregnancy group than in the unplanned-pregnancy group. No significant intergroup differences were noted in the obstetric complications and neonatal outcomes, including congenital malformations.
Conclusion: For women with epilepsy, planning of pregnancy is associated with good seizure control during pregnancy and less fetal exposure to antiepileptic drugs.

英語, 研究論文(学術雑誌), Objective: To determine the association of the N-terminal fragment of precursor protein brain-type natriuretic peptide (NT-proBNP) levels with plasma renin activity (PRA) and plasma aldosterone concentration (PAC) in singleton pregnancies.
Design: Serum NT-proBNP levels, PRA and PAC were determined in 215 blood specimens from 139 women with singleton pregnancies, including 34 and 105 women who did and did not develop hypertensive disorders in pregnancy, respectively. Twenty-five blood specimens were obtained from 25 women who later developed hypertension (systolic BP >= 140 mmHg and/or diastolic BP >= 90 mmHg), but were normotensive at the time of blood sampling.
Results: The serum NT-proBNP levels [pg/ml, median (range), 32 (5-142)] did not change in normotensive women, but increased significantly to 97 (23-436) after the development of hypertension (D/H). The PRA [ng/ml/h, median (range), 7.1 (1-20)] did not change in normotensive women, but decreased significantly to 1.9 (1-16) after D/H. PAC (pg/ml) increased significantly from 397 (94-1750) to 667 (123-2010) between the 2nd and 3rd trimesters in normotensive women. However, as PAC of hypertensive women did not change significantly before and after D/H, PAC [293 (116-1720)] after D/H was significantly lower than that [667 (123-2010)] of the 3rd trimester in the normotensive women. The serum levels of NT-proBNP were significantly and negatively correlated with both PRA and PAC.
Conclusions: The renin-angiotensin-aldosterone system is suppressed in pregnant women with cardiac conditions associated with higher NT-proBNP levels.

英語, 研究論文(学術雑誌), Extraordinary weight gain may be an initial finding in some patients with peripartum cardiomyopathy (PPCM). This case highlights the need for studies of therelationship between degrees of antenatal weight gain and risk of PPCM. A 33-year-old woman exhibited weight gain of 1.0 kg/week (38.5–60.6 kg) between gestational weeks (GW) 12+2 and 33+2 at which dyspnea appeared. Her body weight further increased to 69.1 kg at GW 34+2 at which echocardiography revealed left ventricular dysfunction (ejection fraction = 27%, fractional shortening = 4.0%). She then lost 24 kg in body weight by 4 weeks postpartum. - Clinical features of isolated gestational proteinuria progressing to pre-eclampsia: retrospective observational study

BMJ OPEN, 4, 4, e004870, BMJ PUBLISHING GROUP, 2014年, [査読有り]
英語, 研究論文(学術雑誌), Objectives Some women with isolated gestational proteinuria (IGP) later develop hypertension and are diagnosed with pre-eclampsia (PE). This study was performed to determine whether clinical features of such proteinuria preceding PE (P-PE) differ from those of other PE (O-PE).
Design Retrospective observational study after approval of the institutional review board of ethics.
Setting A single university hospital. Proteinuria was defined as a protein-to-creatinine ratio (mg/mg; P/Cr) of 0.27 in the spot urine specimen. IGP was defined as proteinuria in the absence of hypertension. P-PE was defined as PE in which proteinuria preceded hypertension by more than 2days.
Participants All of 10 and 18 consecutive women with P-PE and O-PE, respectively, who gave birth between January 2008 and August 2013.
Results Proteinuria appeared earlier (at 30.23.0 vs 35.3 +/- 4.3weeks, p=0.001), the P/Cr level was greater at birth (7.28 +/- 2.14 vs 3.19 +/- 2.49, p<0.001), net maternal weight gain during the last antenatal 1week was greater (3.1 +/- 1.8 vs 1.3 +/- 1.7kg, p=0.023) and length of pregnancy was shorter (32.5 +/- 1.9 vs 36.1 +/- 3.6weeks, p=0.001) in women with P-PE than in O-PE. The duration of IGP was 10.0 +/- 5.9days (range 3-20), and the time interval until delivery after diagnosis of PE was 6.1 +/- 8.2days (range 0-23) in 10 women with P-PE. The P/Cr levels at birth were significantly inversely correlated with the antenatal lowest antithrombin activity and fibrinogen levels among the 28 women with PE.
Conclusions Women with P-PE were likely to exhibit greater proteinuria in the urine, greater water retention in the interstitial space and more enhanced coagulation-fibrinolysis, thus suggesting that they may constitute a more severe form of PE than women with O-PE do. - Problems in methods for the detection of significant proteinuria in pregnancy

英語, 研究論文(学術雑誌), AimThe aim of this study was to underscore problems associated with the dipstick test and determination of protein concentration alone in spot-urine (P-test) compared with spot-urine protein-to-creatinine ratio (P/Cr test) and to determine whether urine collection for 24-h test was complete.
Material and MethodsDipstick and P/Cr tests were performed simultaneously in 357 random spot-urine specimens from 145 pregnant women, including 35 with pre-eclampsia. Positive results were defined as 1+ on dipstick test, protein concentration 30mg/dL on P-test, and P/Cr ratio0.27 (mg/mg) on P/Cr test. Sixty-four 24-h urine tests (quantification of protein in urine collected during 24h) were performed in 27 of the 145 women. We assumed that P/Cr ratio0.27 predicted significant proteinuria (urinary protein0.3g/day). The 24-h urine collection was considered incomplete when urinary creatinine excretion was<11.0mg/kg/day or >25.0mg/kg/day.
ResultsForty-four percent (69/156) of specimens with a positive test result on dipstick test contained protein<30mg/dL. Dipstick test was positive for 25.7% (69/269) of specimens with protein<30mg/dL and for 28.8% (79/274) of specimens with P/Cr ratio<0.27. P-test results were positive for 7.3% (20/274) and negative for 18.1% (15/83) of specimens with P/Cr ratio<0.27 and 0.27, respectively. Incomplete 24-h urine collection occurred in 15.6% (10/64) of 24-h urine tests. Daily urinary creatinine excretion was 702-1397mg, while creatinine concentration varied from 16mg/dL to 475mg/dL in spot-urine specimens.
ConclusionDipstick test and P-test were likely to over- and underestimate risks of significant proteinuria, respectively. The 24-h urine collection was often incomplete. - 産科ショックへの対応.研修コーナー

英語, 研究論文(学術雑誌), AimWomen with imminent premature labor (IPL) are transported to a tertiary hospital equipped with neonatal intensive care unit (NICU) even during the night. However, there have been no extensive studies of the occurrence rate of night IPL. The aim of this study was to determine the occurrence rate of night IPL in an area with a population of 2 million.
Materials and MethodsA retrospective analysis was conducted using data collected by the Sapporo Obstetric System for Emergency Patients launched in October 2008, in which women, physicians, and ambulance staff who sought appropriate obstetric/gynecological facilities available in the night (19.00-06.00hours) were informed of candidate hospitals by coordinators through telephone consultation. This system covered the Sapporo area, which has a population of 2000000 and 17000 births annually. Approximately 14% and 86% of women received antenatal care at six and 35 obstetric facilities with and without NICU, respectively, in this area. Night IPL was defined as a threatened premature labor and transport to one of six tertiary hospitals with NICU between 19.00 and 06.00hours the next morning.
ResultsDuring a 4-year period from 1 October 2008 to 30 September 2012, the Sapporo Obstetric System for Emergency Patients received 15823 (mean +/- standard deviation) monthly telephone consultations (range 114-218 per month). The monthly number of patients with night IPL was 3.0 +/- 2.2 (range 0-9 per month).
ConclusionsThe monthly number of cases of night IPL was around three among women who received antenatal care at obstetrics facilities without NICU in an area with a population of 2000000. - Unusual clinical course of preeclampsia heralded by generalized edema

英語, 研究論文(学術雑誌), Preeclampsia monitored by the amount of proteinuria usually does not show amelioration during pregnancy. A 37-year-old nulliparous woman was admitted to our hospital at gestational week (GW) 24(-1/7) due to rapid weight gain (6.2kg/4 weeks) and oligohydramnios. Hypertension (151/91mmHg) appeared at GW 25(-0/7) and proteinuria not detected at GW 24(-0/7) became significant (0.55g/day) at GW 25(-2/7). During the 2 successive weeks after administration of betamethasone at 12mg twice and transabdominal amnioinfusion with 250mL of Ringer's acetate solution at GW 25(-3/7), generalized edema, proteinuria and thrombocytopenia markedly improved: bodyweight, 78.0 to 69.0kg; proteinuria, from 7.1 to 1.3g/day; and platelet count, from 111 to 230 x 10(9)/L. However, intrauterine infection accompanied by non-reassuring fetal status necessitated emergency cesarean section at GW 28(-3/7). Extraordinary bodyweight gain can herald the occurrence of preeclampsia and this weight gain together with signs of preeclampsia can ameliorate even during pregnancy, although its mechanism is unclear. - 双胎妊娠では単胎妊娠に比べ妊娠糖尿病が発症しやすいか?

英語, 研究論文(学術雑誌), Aim The aim of this study was to determine whether the use of transcervical balloon catheter (TCBC) for induction of labor (IOL) is a risk factor for cerebral palsy (CP) associated with umbilical cord prolapse (UCP-CP) in singleton pregnancies with cephalic presentation. Material and Methods Among all 102 infants with CP who were preliminarily determined as caused by antenatal and/or intrapartum hypoxemia by the Japan Council for Quality Health Care until April 2012, all 56 infants who met all of the following criteria were studied: cephalic singleton pregnancy, reassuring fetal status on electronic cardiotocogram at time of admission to obstetric facilities for labor pains, ruptured fetal membranes, and/or IOL, and hypoxic-ischemic encephalopathy at birth. Clinical backgrounds were compared between six infants with UCP-CP and the remaining 50 infants with CP not associated with UCP (non-UCP-CP). Results Frequencies of IOL (83% [5/6] vs 32% [16/50], P=0.0236), use of TCBC (67% [4/6] vs 10% [5/50], P=0.0044), and amniotomy (67% [4/6] vs 24% [12/50], P=0.0494) were significantly higher in the UCP-CP than the non-UCP-CP group. Only TCBC was a risk factor significantly associated with UCP-CP after logistic regression analysis, yielding an odds ratio of 18.0 (95% confidence interval, 2.6-124; P=0.003). Saline volumes of 80-150mL were used for TCBC inflation in the four UCP-CP patients. Conclusion Use of TCBC with a saline volume80mL was a significant risk factor for UCP-CP; however, the absolute risk of UCP-CP was estimated to be very low, approximately one in 7875 TCBC users. - Difference in the D-dimer rise between women with singleton and multifetal pregnancies

英語, 研究論文(学術雑誌), Introduction The differences in the d-dimer rise between women with singleton and multifetal pregnancies have not been studied extensively. Materials and Methods d-Dimer levels were determined in 1089 blood specimens from 1089 women in various stages of pregnancy, including 977 and 112 women with singleton and multifetal pregnancies, respectively. None of the 1089 women developed hypertension or clinical venous thromboembolism during pregnancy or in the postpartum period. Results The d-dimer levels were significantly and positively correlated with gestational week at examination in women with singleton or multifetal pregnancies. The d-dimer levels (μg/ml, mean ± SD [number of specimens]) determined at the 1st trimester did not differ significantly (0.81 ± 0.82 [102] for singleton vs. 1.20 ± 0.77 [7] for multifetal), but those at the 2nd (1.61 ± 1.45 [216] vs. 2.62 ± 2.26 [59]) and 3rd (2.37 ± 2.22 [659] vs. 4.02 ± 2.14 [46]) trimesters were significantly higher in women with multifetal than singleton pregnancies. The 90th percentile value was 4.31 μg/ml for 1089 specimens. A significantly greater number of women exceeded 4.31 μg/ml during the 2nd (16.9% vs. 5.6%, P = 0.0043) and 3rd (34.8% vs. 10.6%, P <
0.0001) trimesters among those with multifetal than with singleton pregnancies. Conclusions The degree of d-dimer rise in pregnancy was greater in women with multifetal than with singleton pregnancies. © 2013 Elsevier Ltd. - 本邦における品胎妊娠における臨床的特徴と短期周産期予後

英語, 研究論文(学術雑誌), Aim It is unknown how to reduce the number of macrosomic neonates among women without hyperglycemia. The aim of this study was to determine clinically useful risk factors for macrosomic neonates among women without hyperglycemia. Material and Methods A retrospective observational study was conducted in 117680 Japanese women without hyperglycemia who gave birth to singleton infants at 37 weeks of gestation or later. Maternal age, parity, fetal sex, pregnancy length, and maternal body composition were studied as possible candidates for risk factors of macrosomic neonates using multivariate logistic regression analyses. Outcome measures were clinically available independent risk factors for macrosomic neonates weighing 4000g or more. Results A total of 1037 (0.9%) women gave birth to macrosomic neonates. A male fetus (odds ratio [95% confidence interval]: 1.99 [1.752.27]), multiparity (1.75 [1.531.99]), pregnancy length of 41 weeks or more (4.28 [3.734.91]) and six characteristics at or above the 90th percentile values consisting of body height (1.65m: 1.70 [1.451.99]), pre-pregnancy body weight (65kg: 1.47 [1.121.93]), pre-pregnancy body mass index (BMI) (25kg/m2: 1.49 [1.161.91]), weight gain during pregnancy (15kg: 2.32 [1.783.03]), BMI gain during pregnancy (6.0kg/m2: 1.52 [1.162.00]), and body weight at delivery (75kg: 2.57 [2.083.17]) were identified as independent risk factors for macrosomia. Conclusion Intervention, such as a counseling on dietary habits leading to a lesser net weight gain may be considered among women suspected of having fetal overgrowth. - 妊娠中のD-dimer 単胎vs多胎

英語, 研究論文(学術雑誌), Objective: To review clinical features and short-term outcomes of triplet pregnancies among Japanese women. Methods: A retrospective analysis was carried out among 320 Japanese women with triplet pregnancies (8 monochorionic, 75 dichorionic, and 150 trichorionic triplets; 87 with unknown placental chorionicity) who delivered at 22 gestational weeks or more between January 2005 and December 2008. Results: Delivery was by cesarean for 315 (98%) women. Gestational age at delivery was 32.3 +/- 2.8 weeks (mean +/- SD) and 33.2 weeks (median), and 97%, 61%, and 14% of women delivered at less than 37, less than 34, and less than 30 gestational weeks, respectively. For live-born infants, mean birth weight was 1762 +/- 437 g, 1608 +/- 396 g, and 1406 +/- 380 g for the heaviest, middle, and lightest triplet, respectively. Eighteen (5.6%) women experienced perinatal mortality (3 triplets for 1 woman, 2, triplets for 4 women, and 1 triplet for 13 women). Perinatal mortality was 25 deaths per 1000 deliveries, and decreased with increasing number of chorionic membranes (125, 44, and 20 per 1000 mono-, di-, and trichorionic triplet deliveries, respectively). Conclusion: Short-term outcomes were good among triplet pregnancies in Japan. The data may be useful for counseling Japanese women with triplet pregnancies.

英語, 研究論文(学術雑誌), Objective To determine the effects of delivery by caesarean on serum levels of N-terminal fragment of precursor protein brain-type natriuretic peptide (NT-proBNP). Methods Serum NT-proBNP levels were determined longitudinally at 24 and 36 weeks of gestation (GW) and on post-partum day 3 and month 1 (PPD3 and PPM1, respectively) in 78 women with normotensive singleton pregnancies. Thirty-nine women underwent caesarean delivery. Plasma renin activity (PRA) and plasma aldosterone concentration (PAC) were determined on PPD3. Effects of maternal demographic characteristics on NT-proBNP levels were also analysed. Results NT-proBNP levels (pg/ml) either in pregnancy or on PPM1 did not differ between women with vaginal and caesarean deliveries (44 ± 24 vs 41 ± 30, 24 GW
37 ± 22 vs 29 ± 22, 36 GW
43 ± 28 vs 39 ± 24, PPM1, respectively). Levels on PPD3 were significantly higher (94 ± 105 vs 247 ± 186, P <
0·0001) in women with caesarean delivery. Among women with caesarean delivery, a larger rise of NT-proBNP on PPD3 occurred in nulliparous than in multiparous women (319 ± 232 vs 185 ± 107, P = 0·023), while no rise occurred among multiparous women with vaginal delivery (108 ± 115 vs 47 ± 27). NT-proBNP levels on PPD3 were significantly and negatively correlated with PRA, PAC and maternal weight loss after childbirth on PPD3. These 3 variables on PPD3 were significantly lower in women undergoing caesarean than vaginal delivery (0·8 ± 0·4 vs 1·9 ± 1·4 ng/ml/h for PRA
70 ± 38 vs 136 ± 88 pg/ml for PAC
2·7 ± 1·2 vs 4·3 ± 1·1 kg for weight loss, each P <
0·0001). Conclusions The transient post-partum rise in serum NT-proBNP may reflect transient volume overload after parturition and is remarkable in nulliparous women, especially after caesarean section. © 2012 Blackwell Publishing Ltd. - Umbilical cord presentation after use of a trans-cervical balloon catheter

英語, 研究論文(学術雑誌), Aim To examine the incidence of umbilical cord presentation, including cord prolapse (UCP) and cord descent (UCD), after the use of a trans-cervical balloon catheter (TCBC), such as a Foley catheter and a metreurynter, for the induction of labor (IOL). Methods A retrospective medical chart review was conducted, focusing on the occurrence of UCP and UCD in 800 women who underwent IOL with a TCBC at five hospitals during the study period (20082009 for two hospitals and 20062009 for three hospitals). The five hospitals had a total of 8245 deliveries during the study period. UCP and UCD were defined as the descent of the umbilical cord in advance of the presenting fetal part in the presence and absence of rupture of fetal membranes, respectively. Results The frequency of IOL using a TCBC with 70250mL of saline varied among the five hospitals from 4.9% to 18.8% (mean +/- SD, 10.7 +/- 5.0%). UCP and UCD occurred in two and four women, respectively, with the frequency of cord presentation varying among the hospitals from 0.0% to 1.8% (mean +/- SD, 0.9 +/- 0.9%); the cord presentation was significantly more likely to occur when 180250mL of saline was used, compared with when 70150mL of saline was used (8.2% [5/61] vs 0.15% [1/662], P<0.0001). A change in the presenting fetal body part also occurred in 0.5% (4/800) of the women. Conclusion The use of a TCBC with 180250mL of saline increases the risk of cord presentation. - 経腹的絨毛採取による出生前診断

英語, 研究論文(学術雑誌), Objective: To determine whether B-type natriuretic peptide (BNP) levels in umbilical cord blood (UCB) and amniotic fluid (AF) are correlated with birth-weight discordances in monochorionic-diamniotic twins.
Study Design: The UCB-BNP and AF-BNP levels were determined at birth in 36 twin-pairs without twin twin transfusion syndrome (TTTS).
Result: Both the UCB-BNP and the AF-BNP levels were significantly higher among twins with either a birth-weight discordance >= 20% (141.6 versus 52.9 pg ml(-1) for UCB BNP, 38.0 versus 17.2 pg ml(-1) for AF BNP) or cardiac dysfunction at birth (167.2 versus 56.3 pg ml(-1) for UCB BNP, 34.9 versus 19.0 pg ml(-1) for AF BNP), compared with neonates without the respective characteristics. The UCB BNP and AF BNP levels in both the larger and the smaller twins were significantly correlated with birth-weight discordance.
Conclusion: Cardiac dysfunction occurs in both larger and smaller co-twins with increasing birth-weight discordances, even in the absence of TTTS.

英語, 研究論文(学術雑誌), Aim: To assess the usefulness of a new method for cesarean section (CS) that is comprised of a transverse incision into the uterine fundus, developed for women with placentas covering the entire anterior uterine wall, and introduced in September 2006. Material and Methods: Review of medical records of 12 and 29 women who underwent CS by the new and conventional methods, respectively, for placenta previa, placenta accreta (accreta, increta and percreta) or placenta widely covering the entire anterior uterinewall in which placenta accreta cannot be excluded, between June 2003 and March 2011. Results: Placenta accreta (67% [8/12] vs 10% [3/29], P = 0.0006) and cesarean hysterectomy (67% vs 10%) were significantly more frequent in the group with the new compared with the conventional method. There were no significant differences between groups with the new and conventional methods in amount of blood loss (1732 ± 1067 vs 1847 ± 1279 g, respectively), prevalence of blood loss >
3000 g (8.3% vs 17%, respectively) or blood transfusion (92% vs 72%, respectively), time required for cesarean hysterectomy (210 ± 58 vs 195 ± 41 min), or neonatal conditions at birth. The amount of blood loss for cesarean hysterectomy was significantly less for the new than conventional method (1959 ± 1025 g vs 4450 ± 1145 g, P = 0.041). Conclusion: The new method was superior to the conventional method with respect to reduction of blood loss during cesarean hysterectomy. However, careful observations are mandatory in women with preserved uterus with respect to a possible increased risk of uterine rupture in future pregnancies. © 2012 The Authors. - Fetal presentation of long QT syndrome - Evaluation of prenatal risk factors: A systematic review

英語, Objective: This systematic review evaluated the existence of risk factors for the fetal manifestation of long QT syndrome (LQTS). Methods: Prenatal cardiac findings suggestive of fetal LQTS were studied using 30 English literature reports extracted from the Pubmed database (1979 to December 2011) using the search terms 'long QT syndrome', 'fetal arrhythmia' and 'congenital heart disease'. Results: LQTS accounted for 15-17% of fetal bradycardias <
110 bpm among fetuses with a normally structured heart. Of the patients with significant prenatal findings of LQTS, 17-35% exhibited a reduced baseline fetal heart rate (FHR) of 110-120 bpm on electronic cardiotocography. Other prenatal signs were sinus or intermittent bradycardia <
110 bpm arising from atrioventricular block, tachyarrhythmias, pleural effusion and hydrops. More than 30% of Japanese infants with LQTS born at or after the mid-1980s exhibited the above-mentioned in utero signs. Conclusions: Fetal factors including a slightly reduced baseline FHR of 110-120 bpm, bradycardia <
110 bpm, tachyarrhythmias or clinical signs of heart failure, such as pleural effusion and hydrops, were associated with a higher frequency of LQTS. The use of these signs may help to increase the perinatal diagnosis of LQTS. Copyright © 2012 S.

英語, 研究論文(学術雑誌), To determine whether a low serum folate level during the first trimester predicts subsequent late abortion, preterm birth, or fetal growth restriction (FGR).
A prospective cohort study involving 5,075 women whose serum folate levels were measured during the first trimester. The participants were informed of their serum folate levels.
The pregnancy duration, birthweight, rate of late abortion/preterm birth, and the rate of FGR did not differ significantly among the four groups classified according to folate status. The mean serum folate levels did not differ among quartiles classified according to the gestational week at the time of delivery. Nineteen of the 20 women with folate deficiency gave birth at term to infants with a birthweight of 3.132 +/- A 321 g; only one infant had FGR.
Low serum folate levels during the first trimester were not associated with the risk of late abortion, preterm birth, or FGR. - Serum levels of N-terminal fragment of precursor protein brain-type natriuretic peptide (NT-proBNP) in twin pregnancy

英語, 研究論文(学術雑誌), Twin pregnancy differs considerably from singleton pregnancy in many aspects and it is unknown how serum NT-proBNP level behaves in women with twin pregnancies. Serum NT-proBNP levels were determined longitudinally at gestational weeks (GW) 24 and 35 in normotensive women with 13 twin and 99 singleton pregnancies. The effects of maternal demographic characteristics on NT-proBNP levels were also analyzed. The serum NT-proBNP levels (pg/ml) in twin pregnancies, which were not different from those in singleton pregnancies at 24 GW (26 +/- 15 vs. 40 +/- 27, respectively, P=0.0718), increased significantly (P=0.0038) and were significantly higher than those in singleton pregnancies at 35 GW (72 +/- 49 vs. 34 +/- 24, P<0.0001). In the analysis including women with singleton pregnancies, the serum levels of NT-proBNP at 35 GW were significantly inversely correlated with pre-pregnancy body mass index (BMI, kg/m(2)) and were significantly higher in nulliparous than multiparous women. Thus, women with twin pregnancy were likely to exhibit an increase in serum NT-proBNP levels in the late stage of pregnancy, especially in lean and nulliparous women. The relative greater blood volume expansion occurring in twin than in singleton pregnancies was considered to be responsible for this phenomenon. (c) 2012 Elsevier B.V.

英語, 研究論文(学術雑誌), Background: Complete automation of high-performance liquid chromatography (HPLC) for determination of hemoglobin F (%Hb F) and hemoglobin A1c (%Hb A1c) levels has made this procedure available in many clinical laboratories. However, the physiological changes in %Hb F during pregnancy and the effects of physiological and supraphysiological levels of %Hb A1c on measurement of %Hb F have not been studied extensively.
Methods: Simultaneous determination of %Hb F and %Hb A1c was conducted in 490 blood samples obtained before (n=21), during the 1st (n=150), 2nd (n=116), and 3rd (n=192) trimesters of pregnancy, and postpartum (n=11) from 357 women, including 60 women with hyperglycemia but unaffected by clinical fetomatemal hemorrhage, by HPLC.
Results: Mean (SD) Hb F levels were 0.71% (0.25%) before pregnancy. The value of 0.82% (0.47%) during the 1st trimester decreased significantly to 0.66% (0.35%) during the 2nd trimester and to 0.58% (0.38%) during the 3rd trimester. The level was 0.62% (0.31%) approximately one year after delivery. Thus, %Hb F was highest during the 1st trimester of pregnancy. The effects of varied %Hb A1c levels on %Hb F measurements were clinically negligible.
Conclusions: The data presented in this work may be used as reference intervals of %Hb F determined with HPLC during pregnancy. (c) 2012 Elsevier B.V. All rights reserved. - Association of Antithrombin Activity with Plasma Aldosterone Concentration and Plasma Renin Activity in Pregnant Women

英語, 研究論文(学術雑誌), Objective. To test the hypothesis that the blood antithrombin (AT) activity is correlated with the plasma aldosterone concentration (PAC), the plasma renin activity (PRA), and/or the PAC-to-PRA ratio during the late stage of pregnancy. Methods. The AT activity, PAC, and PRA were determined within 7 days prior to delivery in 47 women, consisting of 30 normotensive and 6 hypertensive women with singleton pregnancies and 11 normotensive women with twin pregnancies. Results. The median values of the 47 women were 86% of the normal activity level for the AT activity, 442 pg/mL for the PAC, 3.7 ng/mL/h for the PRA, and 108 pg/mL per ng/mL/h for the PAC-to-PRA ratio. Women with an AT activity <= 86% had a significantly lower PRA and a higher PAC-to-PRA ratio than women with an AT activity >86% (3.5 +/- 3.0 vs. 6.6 +/- 4.7 ng/mL/h for PRA, p 0.008; 156 +/- 109 vs. 97 +/- 46 pg/mL per ng/h for PAC-to-PRA ratio, p = 0.021). The AT activity was significantly correlated positively with the PRA and negatively with the PAC-to-PRA ratio. Conclusions. The existence of a common pathophysiological background between a reduced AT activity and a reduced PRA during the late stage of pregnancy was suggested. - Coagulation/Fibrinolysis and laboratory characteristics of pregnant pomen with severely depressed antithrombin activity

英語, 研究論文(学術雑誌), Objective: To examine the pathophysiology of reductions in antithrombin (AT) activity during pregnancy and to better characterize the laboratory features of pregnant women with severely depressed AT activity. Methods: Laboratory variables for blood samples obtained within 5 d prior to delivery were compared among three women groups with severely depressed (<45%, n = 6), modestly depressed (45-69%, n = 10), and normal AT activity levels (>70%, n = 134). Results: Pregnancy-induced hypertension was present in 16.7% (1/6), 30.0% (3/10), and 9.0% (12/134) of the women with the above-mentioned AT activities, respectively. The AT activities were significantly and negatively correlated with the D-dimer, urate, and creatinine levels. The D-dimer level was significantly and negatively correlated with the fibrinogen level. Women with AT activity <45% exhibited markedly elevated levels of hemoglobin and liver enzymes and a significantly lower level of fibrinogen than the other women groups, while the platelet count did not differ among the three groups. Conclusions: Enhanced thrombin generation was involved in the decrease in AT activity. AT activity can decrease in the absence of thrombocytopenia. The liver dysfunction that was seen in cases with severely depressed AT activity may have resulted from impairments in liver perfusion caused by microthromboses generated as a result of the relative lack of AT and/or the shortage of circulating plasma in women with reduced AT activities. - 胎児消化管奇形の出生前診断における骨盤内MRI T1強調画像の有用性についての検討

英語, 研究論文(学術雑誌), Background: Although abruptio placentae causes hypoxia in the infant and thus leading to cerebral palsy (CP), its incidence and clinical features at a nationwide level have not been demonstrated.
Aims: To determine the proportion of abruptio placentae among antenatal and intrapartum causative factors leading to cerebral palsy (CP) and clinical features of such abruptio placentae.
Study design: A review was conducted in 107 infants with CP in whom CP was determined to be due to antenatal and or intrapartum hypoxic conditions by the Japan Council for Quality Health Care until April 2012.
Results: Abruptio placenta was responsible for 28 (26%) of the 107 CP infants, and was the single leading causative factor of CP. Of these 28 women, 22 (79%) exhibited non-reassuring fetal status on admission to obstetric facilities at 36.2 +/- 2.6 weeks of gestation and had neonates with umbilical cord arterial blood pH (base excess) of 6.728 +/- 0.164 (-25 +/- 5.4 mmol/L). In these 22 women, strong abdominal pain and/or profuse vaginal bleeding occurred 159 +/- 99 min prior to admission to an obstetric facility, and the interval until delivery after admission was 47 +/- 31 min. Hypertension or isolated proteinuria preceded clinical events in one (4.5%) and five (23%) of these 22 women, respectively.
Conclusions: Abruptio placentae was responsible for CP in one quarter of all cases determined to be due to antenatal and/or intrapartum hypoxic conditions in Japan. New strategies to shorten the interval until admission to an obstetric facility after onset of symptoms are urgently needed. (C) 2012 Elsevier Ireland Ltd.

英語, 研究論文(学術雑誌), Objective: To assess the prevalence of hyperglycemia according to maternal age and pre-pregnancy body mass index (BMI) among Japanese women before introduction of the current diagnostic criteria. Methods: In a retrospective study, data were analyzed from women with singleton pregnancies who were registered with the JSOG Successive Pregnancy Birth Registry System and who gave birth at 22 weeks of gestation or more between January 2007 and December 2009. Results: Among 138 530 women, 3667 (2.6%) were diagnosed with hyperglycemia including gestational diabetes and diabetes mellitus. The prevalence of hyperglycemia increased with advancing maternal age and increasing BMI. Among women aged <= 24, 25-34, 35-39, and >= 40 years, the prevalence was 0.4%, 0.8%, 1.5%, and 4.0%, respectively, in lean women (BMI<18.5); 1.0%, 1.6%, 2.3%, and 3.1%, respectively, in normal weight women (BMI 18.5-24.9); and 5.7%, 9.2%, 12.9%, and 15.2%, respectively, in obese women (BMI >= 25.0). Of the 1181 newborns with a birth weight of 4000 g or more, 1046 (88.6%) were born to women not diagnosed with hyperglycemia. Conclusion: The results may reflect the baseline prevalence of hyperglycemia and macrosomic neonates (birth weight >= 4000 g) during the era of the old diagnostic criteria in Japan.

英語, 研究論文(学術雑誌), AIMS: To determine the normal reference values for antithrombin (AT) activity, platelet count (Plt), hemoglobin concentration (Hb), and hematocrit value (Ht) immediately before vaginal delivery among healthy pregnant women with singleton pregnancies and to determine association of these blood parameters with fetal growth. METHODS: A complete blood count was performed and the AT activity was examined in 300 consecutive women admitted to hospital at > or = gestational week 36 for labor pains and/or the rupture of fetal membranes. All the women were normotensive and had singleton pregnancies, and none of the women had proteinuria, a weekly weight gain > or = 0.5 kg, or other specific complications upon admission. All the women attempted a vaginal delivery. RESULTS: The medians (5th-95th percentile) were 90% (71-110%) for AT activity, 234x10(9)/L (150-337x10(9)/L) for Plt, 11.0 g/dL (9.5-12.8 g/dL) for Hb, and 34.0% (30.4-38.6%) for Ht. Women with an Hb value of > or = the median (11.0 g/dL) gave birth to significantly smaller infants than their counterparts. CONCLUSIONS: A considerable number of healthy women exhibit a reduced AT activity and/or platelet count immediately before delivery. Hemoconcentration evidenced by a raised Hb value adversely effects on infant growth. Our data may be helpful when considering the normal ranges of these blood parameters for healthy parturient women. - 胎児心拍パターンから胎児QT延長症候群が疑われた1例

英語, 研究論文(学術雑誌), Objective: To determine risk factors for eclampsia among Japanese women with singleton pregnancies. Methods: A retrospective observational study was carried out among patients with and those without eclampsia who were registered on the Japan Society of Obstetrics and Gynecology registry system and who gave birth to singleton infants at 22 weeks or more between 2005 and 2009. Multivariate logistic regression analyses were performed to determine independent risk factors for eclampsia. Results: One-third (75/225) of eclampsia patients developed the condition in the absence of hypertension. Maternal age, nulliparity, and pregnancy-induced hypertension (PIH) were all independent risk factors for eclampsia. The risk of eclampsia decreased by 3.0% per 1-year increase in maternal age, and increased 2.6-fold and 35.4-fold in nulliparous women and women with PIH, respectively. Among teenaged girls with hypertension, the prevalence of eclampsia was 1 case per 28 teenagers. Conclusion: Hypertension alone was not a reliable predictor of eclampsia. More intensified monitoring of nulliparous women and teenaged girls with hypertension is needed in order to prevent eclampsia. (C) 2011 International Federation of Gynecology and Obstetrics.

英語, 研究論文(学術雑誌), Aims : To determine reliably the risk of stillbirth among twin pregnancies.
Methods : A data analysis of 3241 and 6581 women with monochorionic diamniotic (MD) and dichorionic (DD) twins, respectively, who gave birth at >= 22 weeks of gestation.
Results : The prospective risk (per 1000 women) of stillbirth, 25.3 and 11.5 at gestational week 22, decreased to <10.0 at gestational weeks 31 and 28 among the MD and DD twins, respectively. After single intrauterine fetal death, the co-twin died in utero or within 7 days of life more frequently among MD twins than among DD twins [42.7 % (35/82) vs. 2.6 % (2/76); relative risk, 16.2; 95 % confidence interval, 4.0-65.1].
Conclusion : Women with MD twins were 2.2-fold more likely to experience stillbirth than women with DD twins. The prospective risks of stillbirth were <1.0 % for both groups of women at >= 32 weeks of gestation. - 異常妊娠のエピゲノム解析

英語, 研究論文(学術雑誌), Aim: No maternal mortality from pandemic (H1N1) 2009 occurred in Japan. However, the reasons for this lack of maternal deaths remain unknown. This study was performed to investigate how many pregnant women were infected, how many women took antiviral drugs for prophylaxis or treatment, and the rate of vaccination effectiveness.
Material and Methods: A questionnaire study was given to 20 500 postpartum women before leaving obstetric facilities between December 2009 and May 2010 in Hokkaido, asking about antiviral drugs, vaccination, and infection with pandemic (H1N1) 2009.
Results: Approximately one-third (n = 7535) of women given the questionnaires responded. Of these, 268 women (3.5%) indicated that they had contracted influenza. 353 (4.7%) women took antiviral drugs for prophylaxis after close contact with an infected person and 140 (39.7%) of 353 women finally contracted influenza during or after prophylaxis with antiviral drugs, accounting for 52.2% (140/268) of all patients. 229 (85.4%) of 268 patients took antiviral drug for treatment and 6 (2.2%) needed hospitalization, but not mechanical ventilation or intensive care unit. 196 of 268 (73.1%) patients were already infected before the availability of a vaccine. Among 7328 candidates for vaccination, 4921 (67.2%) were vaccinated. Infection occurred in 0.22% (11/4921) and 2.1% (50/2407) of vaccinated and non-vaccinated women, respectively.
Conclusion: Frequent use of antiviral drugs for prophylaxis and treatment may partially explain the low infection rate and no maternal mortality from pandemic (H1N1) 2009 in Japan. Vaccination reduced infection by 89% in pregnant Japanese women. - Risk factors for postpartum hypertension in women with twin pregnancies

英語, 研究論文(学術雑誌), Objective: Which physical findings and blood parameters predict postpartum hypertension remain to be studied in women with twin pregnancies.
Methods: The antenatal systolic and diastolic blood pressures (SBP and DBP, respectively), and 16 laboratory variables were investigated in 150 normotensive women who gave birth to twins.
Results: When the median values of the 18 continuous variables were used as cut-off values, an SBP>120 mm Hg (relative risk [95% confidence interval], 2.81 [1.94-4.08]), a DBP>70 mm Hg (2.42 [1.68-3.49]), an aspartate aminotransferase level>18 U/L (2.22 [1.55-3.19]), and a uric acid level>5.3 mg/dL (1.68 [1.20-2.36]) were independent risk factors for postpartum hypertension.
Conclusions: Antenatal blood pressure measurements and a laboratory work-up may be useful clinically for predicting postpartum hypertension in women with twin pregnancies. - Characteristics of insulin secretion patterns in Japanese women with overt diabetes and gestational diabetes defined according to the International Association of Diabetes and Pregnancy Study Groups criteria

英語, 研究論文(学術雑誌), Aim: To characterize patterns of insulin secretion in women with overt diabetes and gestational diabetes (GDM) defined by the International Association of Diabetes and Pregnancy Study Groups (IADPSG) criteria.
Material and Methods: A total of 228 Japanese women were examined retrospectively. All 228 women had a positive 50-g glucose challenge test (GCT) result at 25.2 +/- 1.2 weeks of gestation and underwent a 75-g glucose tolerance test (GTT) at 27.4 +/- 1.8 weeks of gestation. The immunoreactive insulin levels were determined during the GTT in four groups of pregnant women: five with overt diabetes, 20 with GDM according to both the previous Japan Society of Gynecology and Obstetrics (JSOG) and current IADPSG criteria (traditional GDM group), 43 with GDM according to only the IADPSG criteria (new GDM group), and 160 with non-GDM, but with a positive GCT result.
Results: Attenuated and slow rise in plasma insulin in concert with prolonged hyperglycemia were characteristic in women with overt diabetes, compared with women with GDM in whom excessive insulin secretion in the presence of hyperglycemia was characteristic. The new GDM group did not differ significantly from the traditional GDM group with respect to scores of such indices as the insulinogenic index, the homeostasis model assessment for insulin resistance, and the quantitative insulin sensitivity check index.
Conclusion: Women with overt diabetes have both an impaired capacity for insulin secretion and elevated insulin resistance, while women with GDM exhibit a maintained insulin secretory capacity with an elevated insulin resistance. - Risk Factors of Eclampsia Other Than Hypertension: Pregnancy-Induced Antithrombin Deficiency and Extraordinary Weight Gain

HYPERTENSION IN PREGNANCY, 31, 2, 268, 277, INFORMA HEALTHCARE, 2012年, [査読有り]
英語, 研究論文(学術雑誌), Objective. Recent findings suggest that cerebral edema is a characteristic finding on magnetic resonance imaging in women with eclampsia and that pregnancy-induced antithrombin deficiency (PIATD) may reflect enhanced vascular permeability and may allow the retention of excess water in the interstitial space. Whether PIATD and extraordinary weight gain (EOWG) are risk factors for eclampsia remains to be studied. Methods. The medical records of 11 women with eclampsia among 17,522 deliveries were reviewed retrospectively with respect to changes in the laboratory data and the maternal body weight. PIATD was defined as a perinatal antithrombin activity of <= 65% of the normal activity levels with an antenatal decline and/or a prompt postnatal increase. A large net weight gain during the last two antenatal weeks >97.5th percentile value (>4.01 kg) obtained from 272 control women with neither hypertension nor PIATD was defined as EOWG. Relative risk was obtained on the assumption that the prevalences of PIATD and EOWG were 2.0 and 2.5%, respectively, among 17,511 women who did not develop eclampsia. Results. The duration of hypertension until an eclamptic fit was within 7 days in all 11 cases. PIATD and EOWG were observed in 6 (54.5%) and 2 (18.2%) cases, yielding a relative risk (95% confidential interval) of 57.9 (17.7-188.7) and 8.65 (1.87-39.91) for eclampsia among women with PIATD and EOWG, respectively. Conclusions. PIATD and EOWG may be risk factors for eclampsia. - Plasma Aldosterone Concentration and Plasma Renin Activity Decrease during the Third Trimester in Women with Twin Pregnancies

英語, 研究論文(学術雑誌), Objective: Changes in the plasma aldosterone concentration (PAC) and the plasma renin activity (PRA) have not been extensively studied in women with twin pregnancies. Methods: The PAC and PRA levels were determined during the second and third trimesters and on postpartum day 3 in 14 normotensive women with twin pregnancies and 80 normotensive and 7 preeclamptic women with singleton pregnancies. Results: In women with twin pregnancies, elevated PAC and PRA levels (598 +/- 248 pg/mL and 10.0 +/- 4.7 ng/mL/h, respectively) in the second trimester decreased significantly during the third trimester (to 396 +/- 210 pg/mL and 3.5 +/- 2.9 ng/mL/h, respectively), whereas the corresponding PAC increased significantly (from 421 +/- 207 to 667 +/- 371 pg/mL) and the PRA did not change significantly (from 7.3 +/- 3.4 to 6.9 +/- 4.2 ng/mL/h) in women with normal singleton pregnancies. These changes in the PAC and PRA levels in women with twin pregnancies resembled those in hypertensive women with singleton pregnancies. Conclusions: In women with twin pregnancies, both the PAC and PRA levels were significantly enhanced during the second trimester, whereas those in the third trimester were significantly reduced compared with those in women with normal singleton pregnancies. - 周産期医療と胎盤–最近の話題 10. 胎盤と疾患 3) 常位胎盤早期剥離

英語, 研究論文(学術雑誌), Aim: To identify variables which are strongly associated with fetal growth.
Material and Methods: The study subjects were 203 Japanese women who had a plasma glucose level >= 140 mg/dL (7.8 mmol/L) on a 50-g glucose challenge test but were normoglycemic when challenged with a 75-g oral glucose tolerance test (GTT) according to the criteria previously used in Japan. All the subjects subsequently gave birth to singleton infants. The correlations between the standard deviation for birthweight (birthweight SD) and 15 other variables, including the maternal body mass index (BMI), plasma levels of glucose and insulin on the GTT, and various indices calculated using data from the GTT, were then examined. Univariate and multivariate regression analyses were performed.
Results: Univariate analyses revealed significant correlations between the birthweight SD and the fasting plasma glucose level (P = 0.0063), the pre-pregnancy BMI (P = 0.0001), and the BMI at delivery (P < 0.0001). Only the BMI at delivery remained as a significant factor that was independently correlated with the birthweight SD after a multivariate regression analysis.
Conclusion: The suppression of maternal weight gain, rather than the suppression of the plasma glucose level, may be effective for avoiding infants with overgrowth among Japanese women with mildly impaired glucose tolerance. - Maternal weight gain in twin-twin transfusion syndrome

英語, 研究論文(学術雑誌), Objective. To examine the association between maternal weight gain and twintwin transfusion syndrome (TTTS). Design. Retrospective observational study in two tertiary care centers. Population. All 124 women with monochorionic diamniotic twin pregnancies who gave birth at =16 gestational weeks between 2002 and 2010. Methods. Analysis of chronological relation between maternal weight gain per week (weekly gain) and the diagnosis of TTTS. Main outcome measure. Sonographic diagnosis of TTTS. Results. A weekly weight gain =1.4 kg occurred in 45 women, preceded the diagnosis of TTTS in 22 (78.6%) of the 28 women with TTTS, and was associated with TTTS [women with one weekly weight gain =1.4 kg vs. women with no weekly weight gains =1.4 kg who were diagnosed as having TTTS: 48.9% (22/45) vs. 7.6% (6/79); RR, 6.44; 95%CI, 2.8214.69]. At given gestational weeks between 16 and 27, the mean (+/- SD) prospective risk of the development of TTTS within three weeks was 52.0 +/- 33.8% among women who showed a weekly weight gain =1.4 kg for the first time, whereas the risk of the development of TTTS within one week was 1.6 +/- 1.7% among women who never showed a weekly weight gain =1.4 kg. Conclusions. Excessive maternal weight gain =1.4 kg/week is likely to occur during the development of TTTS. - Changes in D-dimer levels after cesarean section in women with singleton and twin pregnancies

英語, 研究論文(学術雑誌), Objective: To determine how the D-dimer level changes after cesarean section, a topic that has not been studied extensively.
Methods: The D-dimer level (mu g/mL) was measured in 792 and 119 women with singleton and twin pregnancies, respectively, on the day or one day before cesarean section and on postpartum days 1, 3, and 7. None of the women developed venous thromboembolism with clinical symptoms. The data for other two women who underwent a cesarean section and developed pulmonary thromboembolism on postpartum days 0 to 1 were also presented.
Results: The preoperative D-dimer level (median, mu g/mL) of 2.4 increased on postpartum day 1 to 6.0, then decreased to 2.8 on postpartum day 3, and again increased to 4.5 on postpartum day 7 in the singleton pregnancies. A similar pattern, but with slightly higher values, was seen in the twin pregnancies. The 95 percentile value of D-dimer for singleton and twin pregnancies was 6.9 and 10.5 on days -1/0, 19.7 and 25.7 on day 1, 9.7 and 13.5 on day 3, and 15.7 and 17.7 on day 7, respectively. The D-dimer level after pulmonary thromboembolism was greater than the 99 percentile value and the 98 percentile value in the two women, respectively.
Conclusion: Our data regarding the D-dimer level may be helpful when considering the normal range of D-dimer for postpartum women with cesarean delivery. (C) 2011 Elsevier Ltd.

英語, 研究論文(学術雑誌), Object. The aim of this study was to evaluate the feasibility of prenatal LICAM gene testing for X-linked hydrocephalus (XLH).
Methods. In a nationwide study conducted in Japan between 1999 and 2009, the authors identified 51 different LICAM gene mutations in 56 families with XLH. Of these 56 families, 9 obligate carriers requested prenatal gene mutation analysis for the fetal LICAM gene in 14 pregnancies.
Results. In 2004, new clinical guidelines for genetic testing were established by 10 Japanese genetic medicine-related societies. These guidelines stated that the genetic testing of carriers should be done only with their consent and with genetic counseling. Therefore, because females are carriers, since 2004, LICAM gene analysis has not been performed for female fetuses. The authors report on 7 fetal genetic analyses that were performed at the request of families carrying LICAM mutations, involving 3 female (prior to 2004) and 4 male fetuses. Of the 7 fetuses, 3 (1 male and 2 female) carried LICAM mutations. Of these 3, I pregnancy (the male fetus) was terminated; in the other cases, the pregnancies continued, and 3 female and 3 male babies without the XLH phenotype were born.
Conclusions. Prenatal LICAM gene testing combined with genetic counseling was beneficial for families carrying LICAM mutations.

JOURNAL OF PERINATAL MEDICINE, 39, 5, 557, 561, WALTER DE GRUYTER & CO, 2011年09月, [査読有り]
英語, 研究論文(学術雑誌), Aims: To determine the contribution of twin-to-twin transfusion syndrome (TTTS) to preterm birth (PTB) at <37 weeks of gestation among Japanese twin pregnancies.
Methods: An observational study using 3241 MC-BA (monochorionic biamniotic) and 6581 BC (bichorionic biamniotic) twin pregnancies. We focused on TTTS, preterm premature rupture of membranes (PPROM), pregnancy-induced hypertension (PIH), and fetal sex as possible causes of PTB.
Results: PTB was more common in MC-BA than in BC twin pregnancies (66.9% vs. 57.6%, P<0.0001) whereas PTB after PPROM (8.0% vs. 10.0%) and PIH (5.7% vs. 5.9%) was not. PTB after TTTS occurred in 7.3% of women with MC-BA twins. PTB was significantly more common for male-male pairs than for female-female pairs among both MC-BA (69.2% vs. 64.7%) and BC (59.6% vs. 56.3%) twins.
Conclusion: The elevated risk of PTB among MC-BA twins could be explained by the occurrence of TTTS. - Candidates for the determination of antithrombin activity in pregnant women

JOURNAL OF PERINATAL MEDICINE, 39, 4, 369, 374, WALTER DE GRUYTER & CO, 2011年07月, [査読有り]
英語, Background: Some women exhibit a gradual decrease in antithrombin activity until the time of delivery, with antithrombin activity reaching < 65% of the normal level (pregnancy- induced antithrombin deficiency, PIATD). However, the clinical features of such women are not well understood and are unfamiliar to many obstetricians.
Findings: PIATD is more likely to occur as the number of fetuses increases (approx. 1.0%, 10%, and 40% for singleton, twin, and triplet pregnancies, respectively) and in women with hypertension, isolated proteinuria and/or edema. However, normotensive women account for 60% of women with PIATD. Antithrombin can escape from the blood into the interstitial space. Women with PIATD suffer from a decreased plasma volume and are more likely to develop liver dysfunction, irrespective of the presence or absence of hypertension. Because antithrombin activity continues to decrease until the time of delivery in women with PIATD, women with unrecognized PIATD may be identified as patients with so-called "acute fatty liver of pregnancy'' if delivery is delayed.
Conclusion: Knowledge of AT activity in obstetrical practice may improve management of pregnant women. The determination of AT activity should be considered in women with multifetal pregnancies, hypertension, isolated proteinuria and/or edema. - 帝王切開術施行前後における D-dimer 値の正常域の検討-第2報

JOURNAL OF PERINATAL MEDICINE, 39, 1, 23, 26, WALTER DE GRUYTER & CO, 2011年01月, [査読有り]
英語, 研究論文(学術雑誌), Objective: To evaluate whether uterotrophic agents increase the risk of fatal hemorrhagic brain stroke.
Methods: Between 1991 and 1992, there were 230 maternal deaths among 2,420,000 pregnant women in Japan and the causes of these deaths was investigated in 1994. Using information provided in this report, we identified 35 women who died from or were assumed to die from hemorrhagic brain stroke. We assumed that 93% of women would have tried vaginal delivery. The risk of fatal hemorrhagic brain stroke after uterotrophic agent use was calculated according to the assumption that 5.0-40% of women received uterotrophic agents.
Results: Use of uterotrophic agents for induction/augmentation of labor was confirmed in five (14.3%) of the 35 women who died from hemorrhagic brain stroke. The incidence of fatal brain stroke after the use of uterotrophic agents was only significantly higher than that for spontaneous hemorrhagic brain stroke if these agents were administered in <= 6.0% of women.
Conclusions: Because more than 6.0% of women received uterotrophic agents, these agents are unlikely to increase the risk of fatal hemorrhagic brain stroke. - Isolated proteinuria as an initial sign of severe preeclampsia

英語, 研究論文(学術雑誌), Aims: To assess how the number of Japanese pregnant women with hyperglycemia changes after the adoption of the criteria proposed by the IADPSG.
Methods: The study subjects comprised 228 Japanese women with a plasma glucose level >= 7.8 mmol/L on a glucose challenge test and who subsequently underwent a glucose tolerance test among 1038 women with singleton pregnancies. Gestational diabetes mellitus (GDM) is currently diagnosed using the JSOG criteria in Japan.
Results: Of the 228 women, all 25 women with GDM and an additional 43 women without GDM according to the JSOG criteria were classified as having hyperglycemia according to the IADPSG criteria, resulting in an increase of patients with hyperglycemia from 2.4% (25/1038) to 6.6% (68/1038). The number of infants with a birthweight >= 3600 g was significantly larger among the 43 women with newly diagnosed GDM than among the 160 women who remained normoglycemic (14% [6/43] vs. 3.8% [6/160], p = 0.02). The calculated number of patients requiring treatment for a reduction of one infant with a birthweight >= 3600 g was at least 9.8 for women with newly diagnosed GDM.
Conclusion: The IADPSG criteria increase the number of patients by at least 2.7-fold but may be cost-effective with respect to the resulting reduction in macrosomia. (C) 2010 Elsevier Ireland Ltd.

英語, 研究論文(学術雑誌), Objective: We investigated whether ascites samples obtained from pregnant women during cesarean sections contained antithrombin because it is unknown whether antithrombin escapes from the blood and passes into the interstitial space during pregnancy.
Methods: The concentration and activity levels of antithrombin were determined in six ascites samples obtained from six consecutive women who exhibited generalized edema, ascites, and a gradual decline in antithrombin activity.
Results: All six ascites samples contained antithrombin (mean +/- SD, 4.9 +/- 2.2 mg/dL; range, 2.7-8.8 mg/dL) and exhibited an antithrombin activity level of 15.5 +/- 6.0% (range, 10-24%).
Conclusions: Antithrombin escapes from the blood into the interstitial space in pregnant women. This phenomenon partially explains the gradual decline in antithrombin activity observed in these six pregnant women with generalized edema and large volumes of ascites. - Marked gestational edema as a clinical sign of life-threatening condition

英語, 研究論文(学術雑誌), A 35-year-old Japanese nulliparous woman exhibited rapid weight gain (6 kg/7 days), reduced antithrombin activity and platelet count at 37 weeks of gestation without hypertension or proteinuria, and underwent cesarean section. Postnatally, pulmonary edema developed for 7 days, with transient hypertension and proteinuria, and bodyweight loss (14.6 kg) by 14 days postpartum. Platelet count and antithrombin activity normalized promptly postpartum. Despite a life-threatening clinical condition due to enhanced vascular permeability, neither hypertension nor proteinuria appeared antenatally. Determining antithrombin activity and platelet count may be useful for distinguishing between women with pathological edema and physiological edema. - 日本においてはPandemic (H1N1) 2009による妊婦死亡はなかった

英語, 研究論文(学術雑誌), Objective: This retrospective study was performed to characterize the laboratory features and water metabolism of women with pregnancy-induced antithrombin deficiency (PIATD).
Methods: Among 1493 women who gave birth to a singleton infant at our institution, 114 women who developed PIATD and/or pregnancy-induced hypertension (PIH) were reviewed with respect to perinatal changes in laboratory variables (hematocrit value, fibrinogen, fibrinogen degradation product, D-dimer, uric acid, aspartate aminotransferase, lactate dehydrogenase) and body weight. PIATD was defined as a gradual decline in antithrombin (AT) activity to <= 65% of normal activity levels. One hundred and fourteen women with neither PIATD nor PIH and matched for the cesarean delivery rate were selected as a control group.
Results: Of the 81 women who developed PIH, 19 (23.4%) also developed PIATD. Thirty-three women developed PIATD in the absence of PIH. Coagulation-fibrinolysis was significantly more enhanced and the postpartum reduction in the hematocrit value was significantly larger in women with PIATD, irrespective of the presence or absence of hypertension, than in women without PIATD. The postpartum decrease in body weight was significantly smaller in women with PIATD, irrespective of the presence or absence of hypertension.
Conclusions: A decrease in AT activity may occur in the absence of hypertension. Even in the absence of hypertension, a decreased plasma volume and enhanced coagulation-fibrinolysis seem to characterize women with PIATD. The monitoring of AT activity may help in distinguishing pregnant women with these insidious risks. - 妊婦における血中から間質へのアンチトロンビンの漏出の根拠

英語, We conducted a literature review of 55 pregnancies with symptomatic Group A streptococcus (Streptococcus pyogenes) infection reported in English (20 cases), French (2 cases) and Japanese (33 cases) to seek ways of improving prognosis. Multiparous women (83% [39/47]) in the third trimester (90% [47/52]) were prone to infection from winter to spring (75% [21/28]). Onset was heralded by flu-like symptoms, such as high fever (94% [46/49]), with upper respiratory (40% [22/55]) and/or gastrointestinal symptoms (49% [27/55]). Characteristic findings were early onset of shock (91% [50/55]) and infection-induced strong uterine contraction (73% [40/55]) suggestive of placental abruption. The clinical course was too acute and severe to rescue the mother (58% [32/55] died) and/or infant (66% [39/59] died). However, outcome has improved over the last decade, with rescue of 68% (15/22) of the mothers since 2000, and early use of antibiotics (71% [22/31] survived) and use of intravenous immunoglobulin (91% [10/11] survived) were associated with favourable outcome. Early use of antibiotics and intravenous immunoglobulin may improve outcome of pregnant women suffering from flu-like symptoms, shock and strong uterine contractions suggestive of placental abruption.

英語, 研究論文(学術雑誌), Cleft of the soft palate (CSP) and the hard palate are subtypes of cleft palate. Patients with either condition often have difficulty with speech and swallowing. Nonsyndromic, cleft palate isolated has been reported to be associated with several genes, but to our knowledge, there have been no detailed genetic investigations of CSP. We performed a genome-wide linkage analysis using a single-nucleotide polymorphism-based microarray platform and successively using microsatellite markers in a family in which six members, across three successive generations, had CSP. A maximum LOD score of 2.408 was obtained at 2p24.2-24.1 and 2p21-p12, assuming autosomal dominant inheritance. Our results suggest that either of these regions is responsible for this type of CSP.

英語, 研究論文(学術雑誌), We present the first report of complete hydatidiform mole (HM) with coexisting dichorionic diamniotic twins. This pregnancy was achieved after testicular sperm extraction and intracytoplasmic sperm injection (ICSI) for azoospermia in the woman's husband. Standard in vitro fertilization may cause multisperm fertilization and increase triploid partial HM and complete HM, which arise from dispermic fertilization. In contrast, ICSI can avoid multisperm fertilization. In our case, paternal isodisomy in the molar tissue was confirmed by microsatellite analysis suggesting that it resulted from duplication of a haploid paternal genome following monospermic fertilization of an inactivated oocyte or from monospermic fertilization of an inactivated oocyte with a diploid sperm. Although the patient was eager to continue the pregnancy, the size of the HM component increased rapidly and termination of the pregnancy was required for pre-eclampsia-like symptoms at 15 weeks of gestation. After the operation, chemotherapy was initiated for persistent trophoblastic disease. - Pregnancy outcome of women who developed proteinuria in the absence of hypertension after mid-gestation

英語, 研究論文(学術雑誌), Objective: To characterize the clinical features of women with singleton pregnancies who develop proteinuria in the absence of hypertension after mid-gestation.
Methods: Seventy-nine women who developed proteinuria and/or hypertension at and after 20 weeks of gestation were reviewed, focusing on the gestational week at which significant proteinuria (>0.3 g/day) and/or hypertension developed.
Results: Thirty-seven (47%) women exhibited new-onset proteinuria (>0.3 g/day) in the absence of hypertension, 33 (42%) exhibited new-onset hypertension in the absence of proteinuria, and 9 (11%) exhibited both proteinuria and hypertension. Nineteen (51%) of 37 women who exhibited new proteinuria in the absence of hypertension and 5 (15%) of 33 women who exhibited new hypertension in the absence of proteinuria progressed to preeclampsia (P=0.002). Among women who exhibited new proteinuria, 10 (77%) out of 13 women and 9 (38%) out of 24 women who developed proteinuria at <32 weeks and >= 32 weeks, respectively, progressed to preeclampsia (P=0.022).
Conclusions: Women with new-onset proteinuria in the absence of hypertension may be more likely to progress to preeclampsia than women with a presumptive diagnosis of gestational hypertension, and the likelihood of progression may be significantly greater among women with earlier presentation. - 妊娠性血小板減少症ならびに妊娠性アンチトロンビン欠乏症の分娩前後のフィブリノーゲン、FDP、D-dimer、Ht 値の推移 : 妊娠高血圧症候群との対比

英語, 研究論文(学術雑誌), Imprinted genes are expressed in a parent- of- origin manner and are located in clusters throughout the genome. Aberrations in the expression of imprinted genes on human Chromosome 7 have been suggested to play a role in the etiologies of Russell- Silver Syndrome and autism. We describe the imprinting of KLF14, an intronless member of the Kru " ppel- like family of transcription factors located at Chromosome 7q32. We show that it has monoallelic maternal expression in all embryonic and extra- embryonic tissues studied, in both human and mouse. We examine epigenetic modifications in the KLF14 CpG island in both species and find this region to be hypomethylated. In addition, we perform chromatin immunoprecipitation and find that the murine Klf14 CpG island lacks allele- specific histone modifications. Despite the absence of these defining features, our analysis of Klf14 in offspring from DNA methyltransferase 3a conditional knockout mice reveals that the gene's expression is dependent upon a maternally methylated region. Due to the intronless nature of Klf14 and its homology to Klf16, we suggest that the gene is an ancient retrotransposed copy of Klf16. By sequence analysis of numerous species, we place the timing of this event after the divergence of Marsupialia, yet prior to the divergence of the Xenarthra superclade. We identify a large number of sequence variants in KLF14 and, using several measures of diversity, we determine that there is greater variability in the human lineage with a significantly increased number of nonsynonymous changes, suggesting humanspecific accelerated evolution. Thus, KLF14 may be the first example of an imprinted transcript undergoing accelerated evolution in the human lineage. - 偽性バーター症候群合併妊娠の1例 : 妊娠高血圧症候群モデル?

英語, 研究論文(学術雑誌), To examine the association between colonization by two newly classified species of genital ureaplasmas (Ureaplasma parvum and U. urealyticum) in early pregnancy and subsequent late abortion or preterm birth at < 34 weeks of gestation, four species of genital mycoplasmas-Mycoplasma genitalium, M. hominis, U. parmin, and U. urealyticum-as well as Chlamydia trachomatis and Neisseria gonorrhoeae were examined by PCR-based methods in a prospective cohort study of 877 women with singleton pregnancies at < 11 weeks of gestation. Antibiotics were used only in cases in which C. trachomatis and/or N. gonorrhoeae was detected. Multivariate logistic-regression analysis was used to assess independent risk factors after taking maternal low body weight and past history of preterm birth into account. M. genitalium, M. hominis, U. parvum, U. urealyticum, C. trachomatis, and N. gonorrhoeae were detected in 0.8%, 11.2%, 52.0%, 8.7%, 3.2%, and 0.1% of these 877 women, respectively. Twenty-one (2.4%) women experienced late abortion or preterm birth at < 34 weeks of gestation. Three factors-detection of U. parmin in the vagina (odds ratio [OR), 3.0; 95% confidence interval [CI], 1.1 to 8.5); use of antibiotics, such as penicillin and cefatrizine, for incidental inflammatory complications before 22 weeks of gestation (OR, 4.2; 95% CI, 1.6 to 10.0); and past history of preterm birth (OR, 10.4; 95% CI, 2.7 to 40.5)-were independently associated with late abortion and preterm birth. In conclusion, vaginal colonization with U. parmin, but not U. urealyticum, is associated with late abortion or early preterm birth. - Changes in antithrombin activity and platelet counts in the late stage of twin and triplet pregnancies

英語, 研究論文(学術雑誌), It is possible that women with triplet pregnancies are more likely to exhibit pregnancy-induced antithrombin deficiency, gestational thrombocytopenia, and perinatal elevation in serum aspartate aminotransferase (AST) than women with twin pregnancies. We retrospectively reviewed changes in antithrombin activity, platelet count, and blood chemistry in 23 twin and seven triplet pregnancies in which the mothers received antenatal care and gave birth in our hospital during 1999 and 2001. Both antithrombin activity and platelet counts gradually decreased until delivery, then promptly increased after delivery in both twin and triplet pregnancies. A significantly larger number of women developed gestational thrombocytopenia of < 100 x 10(9)/L (43% [three of seven] versus 4.3% [one of 23]; p < 0.01) and pregnancy-induced antithrombin deficiency of < 60% of normal activity (57% [four of seven] versus 17% [four of 23]; p < 0.05) in triplet than in twin pregnancies. Eight women with pregnancy-induced antithrombin deficiency, including three women with gestational thrombocytopenia, were significantly more likely to develop perinatal elevations of AST, lactate dehydrogenase, serum creatinine, fibrin/fibrinogen degradation products, and D-dimer than were those without pregnancy-induced antithrombin deficiency. These findings suggest that women with triplet pregnancies are at an increased risk of the HELLP syndrome and acute fatty liver of pregnancy compared with women with twin pregnancies. - Endothelial nitric-oxide synthase antisense (NOS3AS) gene encodes an autophagy-related protein (APG9-like2) highly expressed in trophoblast

The precise role of autophagy in mammalian development and potential involvement in disease remain to be discerned. Yeast Atg9p is the first integral membrane protein shown to be essential for the cytoplasm to vacuole targeting (Cvt) pathway and autophagy, whereas its mammalian functional orthologue has yet to be identified. We have identified two human genes homologous to yeast Atg9p and designated these as APG9L1 and APG9L2. We have previously identified APG9L2 as NOS3AS, which participates in the post-transcriptional regulation of the endothelial nitric-oxide synthase (NOS3) gene on chromosome 7 through its antisense overlap. In human adult tissues, APG9L1 was ubiquitously expressed, whereas APG9L2 was highly expressed in placenta (trophoblast cells) and pituitary gland. In transient transfection assays we found that both proteins were primarily localized to the perinuclear region and also scattered throughout the cytosol as dots, a subset of which colocalized with an autophagosome-specific marker LC3 under starvation conditions. Finally, by the small interfering RNA-mediated knockdown of APG9L1 in HeLa cells, we demonstrated that APG9L1 is essential for starvation-induced autophagosome formation. In addition, APG9L2 can functionally complement APG9L1 in this process. These results, taken together with those of phylogenetic and sequence analyses, suggest that both APG9L1 and APG9L2 are functionally orthologous to the yATG9 in autophagosome formation. Moreover, APG9L2 is a vertebrate-specific gene that may have gained critical roles in mammalian-specific developmental events, such as placentation, through rapid evolution. - Magnetic resonance image findings of placental lake: report of two cases

英語, 研究論文(学術雑誌), Two cases with a large cystic mass within the placenta are reported. By ultrasonography, it was found that both women had a subchorionic hypoechoic lesion (11.0 x 4.8 x 4.0 cm and 6.6 x 3.7 x 2.2 cm, respectively) at 24 and 35 weeks of gestation, respectively. In both cases, turbulent blood flow generated by a pulsatile jet flow (pulse rate; 40 to 60 beats per minute) into the cystic lesion seen on real-time imaging and lesions being low intensity on T1-weighted and isointensity on T2-weighted magnetic resonance image suggested that they contained fresh maternal blood. In both cases, the sonolucency of the lesions did not change until cesarean deliveries of females, both of whom were small-for-gestational-age infants (1940 a at 37 weeks and 2195 g at 37 weeks, respectively). Biochemical analysis of the fluid in the cystic lesion sampled during the cesarean section in the latter case confirmed that the fluid had originated from the maternal blood. These lesions histologically corresponded to large avillous areas surrounded by normal villi. Thus, a huge placental lake was diagnosed in both cases.

英語, 研究論文(学術雑誌), Objective: The aim of this study was to assess pregnancy loss patterns in women with repeated miscarriage (RM), according to fetal chromosome karyotypes and aetiologies of RM. Methods: In this cohort study, 168 fetal chromosome karyotypes of miscarriages were investigated. The pregnancy loss patterns were compared between 75 miscarriages from RM women who had a history of two or more consecutive miscarriages and 93 miscarriages from control women whose previous pregnancies ended in live births without a history of RM. By serial ultrasonography, embryo loss (EL) was defined as miscarriage before fetal heat movement was identified and fetal loss (FL) as miscarriage after fetal heat movement was identified. The EL rate was calculated as EL/(EL+FL). Results: The EL rate (66.7%) in miscarriages with normal karyotypes among RM women (n=42) was higher (P<0.05) than that (45.7%) in controls (n=46), while the EL rate (30.3%) in miscarriages with abnormal karyotypes among RM women (n=33) did not differ from that (25.5%) in the controls (n=47). The EL rate (71.4%) in miscarriages with normal karyotypes among unexplained RM women (n=21) was much higher (P<0.05) than that in the controls. Conclusions: By evaluating fetal karyotypes, we demonstrated for the first time that EL was predominant in miscarriages with normal karyotype among RM women. - Post-transcriptional regulation of endothelial nitric-oxide synthase by an overlapping antisense mRNA transcript

英語, 研究論文(学術雑誌), Endothelial nitric-oxide synthase ( eNOS) mRNA levels are abnormal in diseases of the cardiovascular system, but changes in gene expression cannot be accounted for by transcription alone. We found evidence for the existence of an antisense mRNA (sONE) that is derived from a transcription unit ( NOS3AS) on the opposite DNA strand from which the human eNOS (NOS3) mRNA is transcribed at human chromosome 7q36. The genes are oriented in a tail-to-tail configuration, and the mRNAs encoding sONE and eNOS are complementary for 662 nucleotides. The mRNA for sONE could be detected in a variety of cell types, both in vivo and in vitro, but not vascular endothelial cells. In contrast, expression of eNOS is highly restricted to vascular endothelium. Most surprisingly, interrogation of transcriptional events across NOS3/NOS3AS genomic regions, using single- and double-stranded probes for nuclear run-off analyses and chromatin immunoprecipitation-based assessments of RNA polymerase II distribution, indicated that NOS3 and NOS3AS gene transcription did not correlate with steady-state mRNA levels. We found strong evidence supporting a role for NOS3AS in the post-transcriptional regulation of NOS3 expression. RNA interference-mediated inhibition of sONE expression in vascular smooth muscle cells increased eNOS expression. Overexpression of sONE in endothelial cells blunted eNOS expression. Finally, the histone deacetylase inhibitor trichostatin A is known to regulate the expression of eNOS via a post-transcriptional mechanism. We found that trichostatin A treatment of vascular endothelial cells increased expression of sONE mRNA levels prior to the observed decrease in eNOS mRNA expression. Taken together, these results indicate that an antisense mRNA ( sONE) participates in the post-transcriptional regulation of eNOS and provide a newer model for endothelial cell-specific gene expression. - A previously unidentified MECP2 open reading frame defines a new protein isoform relevant to Rett syndrome

英語, 研究論文(学術雑誌), MEST is one of the imprinted genes in human. With the assistance of our integration map and the complete sequence in the registry, we mapped a total of 16 genes/transcripts at the 1.5-Mb MEST-flanking region at 7q32. This region has been suggested to form an imprinted gene cluster, because MEST and its three flanking genes/transcripts (MESTIT1, CPA4, and COPG2IT1) were reported to be imprinted, although two (TSGA14 and COPG2) were shown to escape imprinting. In this study, 10 other genes/transcripts were examined for their imprinting status in human fetal tissues. The results indicated that 8 genes/transcripts (NRF1, UBE2H, HSPC216, KIAA0265, FLJ14803, CPA2, CPA1, and DKFZp667F0312) were expressed biallelically. The imprinting status of two (TSGA13 and CPA5) was not conclusive, because of their weak and/or tissue-specific expression and inconstant results. These findings provided evidence that only 4 of the 16 genes/ transcripts located to the region show monoallelic expression, while others are not involved in imprinting. Therefore, it is less likely that the MEST-flanking 7q32 region forms a large imprinted domain. (C) 2003 Elsevier Inc.

英語, 研究論文(学術雑誌), Intrauterine fetal growth restriction is a multifactorial disorder, and its aetiology includes both environmental and genetic components. We aimed to investigate whether maternal genetic polymorphisms of metabolic enzymes affects fetal growth and pregnancy duration. Genomic DNA was obtained from 134 women who experienced singleton deliveries beyond 24 weeks of gestation. Maternal age, birth weight, gestational age at birth and frequencies of fetal growth restriction, prematurity and pregnancy-induced hypertension were compared among genotypic subgroups of cytochrome P450 (CYP) and glutathione S-transferase (GST) genes. The polymorphisms of CYP1A1 (MspI), CYP17 (MspAI) and GSTP1 (BsmAI) genotypes, and the presence or absence of GSTM1 and GSTT1 genes were analysed by PCR-based methods. The frequency of fetal growth restriction (<10th percentile/<-1.5 SD; 22.7%/11.4%) in 44 women who were homozygous for the A1 allele (A1A1) of CYP17 was significantly higher than that (7.8%/2.2%) in 90 women who carried the A2 allele (A1A2/A2A2) of CYP17 (P < 0.05), with an odds ratio =3.41 (95% confidence interval = 1.18-9.84). The gestational age at birth (mean +/- SD, 37.5 +/- 3.1 weeks) in 67 women with GSTM1 null genotype was significantly lower than that (38.5 +/- 2.4 weeks) in 67 women who carried GSTM1 (P < 0.05). The polymorphism of CYP17 that encodes the cytochrome P450c17alpha enzyme might be associated with the pathophysiology underlying fetal growth restriction. - Atp10a, the mouse ortholog of the human imprinted ATP10A gene, escapes genomic imprinting

英語, 研究論文(学術雑誌), The mouse Atp10a gene is located at the border of an imprinted domain distal to the p-locus on mouse chromosome 7. The localization of Atp10a neighboring the maternally expressed gene Ube3a in the imprinted domain and an unusual inheritance pattern of the obesity phenotype with a p-locus deletion have suggested that Atp10a might be imprinted and associated with body fat. Recently, its human ortholog, ATP10A, was identified as the second imprinted gene with maternal expression in the human chromosome 15q11-q13 imprinted domain. To elucidate the imprinting status of Atp10a, we performed expression analysis in various tissues from reciprocal crosses between C57BL/6 and PWK (divergent strains of Mus musculus) mice. The results revealed that Atp10a was biallelically expressed in all tissues examined. Furthermore, there was no differential methylation in the CpG island and no antisense transcripts of the gene. These findings suggest that the mouse Atp10a gene escapes genomic imprinting. (C) 2003 Elsevier Science (USA).

英語, 研究論文(学術雑誌), By a search for novel human imprinted genes in the vicinity of the imprinted gene MEST, at chromosome 7q32, we identified the carboxypeptidase A4 gene (CPA4) in a gene cluster of the carboxypeptidase family, 200kb centromeric to MEST. Because CPA4 was originally identified as a protein induced in a prostate cancer cell line (PC-3) by histone deacetylase inhibitors, and was located at the putative prostate cancer-aggressiveness locus at 7q32, we investigated its imprinting status in fetal tissues and in adult benign hypertrophic prostate (BPH). RT-PCR using four intragenic polymorphisms as markers showed that CPA4 was expressed preferentially from the maternal allele in the fetal heart, lung, liver, intestine, kidney, adrenal gland, and spleen, but not in the fetal brain. It was also preferentially expressed in the BPH. These findings support that CPA4 is imprinted and may become a strong candidate gene for prostate cancer-aggressiveness. As a Silver-Russell syndrome (SRS) locus has been proposed to be located to a region near MEST and to be involved in imprinting, CPA4 would have been a candidate gene for SRS. However, analysis of ten SRS patients revealed no mutations in CPA4. - [Analysis of the imprinted domain in the vicinity of MEST at chromosomal 7q32].

英語, 研究論文(学術雑誌), We identified the gene TSGA14, encoding the testis-specific protein A14 and located 50 kb proximal to the imprinted gene MEST in a head-to-head orientation. TSGA14 has at least two transcripts: a long-type (I-type) transcript, and a short-type (s-type) transcript. Since the COPG2IT1 gene in the vicinity of MEST has been reported to be imprinted, we presumed that TSGA14 might also be imprinted. We thus analyzed the imprinting status of TSGAI41-type and s-type transcripts in various fetal tissues. TSGAI41-type transcript, which consists of 11 exons and encodes a 1-type isoform with 373 amino acids, is biallelically expressed in the fetal tissues including the testis. TSGA14 s-type transcript, which consists of three exons and encodes a s-type isoform with 54 amino acids, also showed biallelic expression in the fetal brain and liver. No allele-specific methylation in the TSGA14 CpG island was detected. The fact that COPG2 and TSGA14, both neighbors of MEST, escape genomic imprinting suggests that the 7q32 imprinted region may be small and not similar to other imprinted domains, such as those at 15q11-13 and 11p15.5.

英語, 研究論文(学術雑誌), Transforming growth factor-beta1 (TGF-beta1) is a multifunctional cytokine that is produced in the platelet, bone, placenta, and other tissues. It acts as a growth inhibitor in many types of cells, and also mediates extracellular matrix production and immunosuppression. Mutations in the specific domain of its gene (TGFBI) cause Camurati-Engelmann disease, a bone-sclerosing disorder, and those in other domains may be associated with osteoporosis. We identified 106 single-nucleotide polymorphisms and 11 other types of variations in TGFBI and six other genes. These genes were TGF-beta type I receptor gene (TGFBR1), TGF-beta type II receptor gene (TGFBR2), SMAD2 gene (SMAD2), SMAD3 gene (SMAD3), SMAD4 gene (SMAD4), and SMAD7 gene (SMAD7), all of which compose the TGF-beta1 signaling pathway. We also estimated allele frequencies of these DNA polymorphisms among 48 Japanese individuals. Our data will provide a useful resource for the study of disease susceptibility. - Massive intravenous immunoglobulin treatment in women with four or more recurrent spontaneous abortions of unexplained etiology: Down-regulation of NK cell activity and subsets

英語, 研究論文(学術雑誌), Problem: The aims of this study were to investigate the efficacy of massive intravenous immunoglobulin (MIVIg) treatment for women with recurrent spontaneous abortion (RSA) of unexplained etiology, and to investigate changes in peripheral natural killer (NK) cell activity and subsets.
Method of study: MIVIg treatment was performed in 18 pregnancies from 15 women with 4 or more consecutive RSA of unexplained etiology. NK cell activity and subsets were assessed in 8 of the pregnancies.
ResultS: 14 pregnancies resulted in live births and 4 resulted in abortions with chromosome abnormality. The pre-infusion NK cell activity (mean +/- SID, 40.9 +/- 17.0%) at 4.4 +/-0.5 weeks of gestation (GW) decreased to 15.0 +/-7.9% at post-infusion status (5.4 +/-0.5 GW). Pre-infusion percentages of CD56(+)CD16(-) cells (3.5 +/-2.1%) and CD56(+)CD16(-) cells (16.8 +/-8.8%) decreased to 3.0 +/-2.2% and 11.1 +/-6.9%, respectively. after MIVIg treatment.
Conclusions: MIVIg treatment was effective in all 14 pregnancies from RSA women of unexplained etiology, excluding 4 abortions with chromosome abnormality. Peripheral NK cell activity and subsets were suppressed by MIVIg treatment. - Management of pregnancy with congenital antithrombin III deficiency: Two case reports and a review of the literature

英語, 研究論文(学術雑誌), Background. The number and percentage of viable vaginal polymorphonuclear leukocytes (vPMNs) are known to be increased in women who experience preterm labor. Whether those parameters may be associated with the presence of histologic chorioamnionitis (CAM) is not known.
Methods. We investigated prospectively 39 women at 26.3 +/- 6.2 weeks of gestation. The following were determined in vaginal washings. total number of vPMNs and the percent that were viable, the pH, and the concentrations of granulocyte elastase and interleukin-8 (IL-8). In addition, the while blood cell count and the serum level of C-reactive protein were determined in peripheral blood. The placenta and the umbilical cord were examined histologically with special reference to the presence of CAM. The optimal cutoff value for prediction of histologic CAM was obtained for each variable using receiver operating characteristic curves. A multivariate logistic-regression model was used to determine the independent risk factors for this disorder.
Results. Histologic CAM was present in ten women (37.1+/-3.8 weeks) and absent in 29 women (38.2+/-1.5 weeks). The total number of vPMNs, the percent of viable vPMNs, and the IL-8 level were all significantly increased in the women with CAM, in contrast to those without CAM. When the optimal cutoff value for each of seven covariates was entered into the model, only the percent of viable vPMNs, greater than or equal to 11%, demonstrated a significant relationship with histologic CAM (odds ratio 26.9; 95% confidence interval 1.3 to 545; p<0.05).
Conclusions. Women with a % viability of vPMNs of greater than or equal to 11% were at a significantly higher risk for histologic CAM. Data suggest that an influx of PMNs into the vagina occurs continuously in patients with histologic CAM. - 心筋炎を確認したヒトパルボウイルスB19胎内感染の1例

英語, 研究論文(学術雑誌), The aims of the present study were to determine recent trends in the prevalence of Down syndrome (DS) in Japan, and to determine whether recent changes in demographic and social habits and access to prenatal diagnosis have influenced the livebirth rates of DS. Livebirth statistics indicate that the birth rate in Japan has decreased for women in their 20s and has increased for those in their 30s and 40s. During an 18-year period between 1980 and 1997, 1,299 consecutive DS infants were born among a total of 2,232,694 births, a rate corresponding to approximately 10% of all births in Japan over the same period. The increasing risk of DS with advancing maternal age was confirmed. The overall prevalence was 5.82 DS births per 10,000 livebirths (8.3-9.7 per 10,000 after correction according to the estimated ascertainment ratio: 60-70%). The prevalence rate by year of child birth represents a statistically significant increase (P = 0.001). In conclusion, recent trends in the prevalence of DS in Japan from 1980 to 1997 failed to show a consistent tendency to decrease, probably because of the concomitant increase in pregnancy in advanced maternal age. - わが教室における乳癌検診

cultured skin fibroblasts, 10/90) from 386 metaphases, and the marker chromosome appeared as a small non-fluorescent acrocentric chromosome. All autosomes appeared normal, and no normal Y chromosome could be demonstrated. Analysis of 26 Y-chromosome loci by molecular techniques such as PCR, Southern analysis using multiple Y-specific DNA probes, and Hae III restriction endonuclease assessment of male-specific repeated DNA in the heterochromatic region of the Y chromosome, and fluorescence in situ hybridization (FISH), revealed the marker was derived from a Y chromosome including p terminal to q11.23, and paracentric inversion in the remaining Y long arm. The formation of testes can be considered as existence of SRY (sex-determining region of Y) as a testis-determining factor. The present report illustrates the importance of FISH and molecular techniques as a complement to cytogenetic methods for accurate identification and characterization of chromosome rearrangements in prenatal diagnosis. - 妊娠経過中に突然母体にDIC傾向を認めた胎便性腹膜炎の一症例

耐糖能異常ならびにインスリン抵抗性と児の出生体重ならびに胎児異常との関連について50gGCT陽性(.140mg/dL)であった228名を対象に検討した。75gOGTT結果により分類された妊娠糖尿病(GDM、25名)群、境界群(1点のみ異常39名、陰性群(3点すべて正常164名)のII(insulinogenic index)異常(<0.4)頻度はそれぞれ44.0%、23.1%、13.4%であり、HOMA-R異常(.2.5)頻度はそれぞれ40.0%、25.6%、10.4%であった。インスリン抵抗性増大(HOMA-R.2.5)は児出生体重.+2SDならびに胎児異常(とくに外胚葉由来)をよく予測(OR3.5[1.4-8.7]、7.6[1.6-35.5])した。GDM妊婦中、血糖調節不良例(分娩前1ヵ月以内HbA1c>5.8%)では良好例に比して児出生体重.+2SDの危険が高かった(4/8vs2/17)。GDM群25例中5例(20.0%)は後に糖尿病と診断された。これらの結果はGDM例中には高頻度に糖尿病妊婦が含まれていること、GDMはインスリン抵抗性増大ならびにインスリン分泌能低下と関連があること、インスリン抵抗性増大(HOMA-R.2.5)は児出生体重.+2SDならびに胎児異常(とくに外胚葉由来)を予測すること、ならびに血糖調節不良例では児出生体重.+2SDの危険が高いことを示した。(著者抄録), (一社)日本糖尿病・妊娠学会, 日本語 - 社会的リスクと周産期医療 札幌圏における未受診妊婦の実態調査

The study group consisted of pregnant women at 20 weeks or more gestation with gestosis (G group, 12 cases with hypertension, 10 cases without hypertension) and 23 women without gestosis (N group). The blood pressure (BP) of each patient was recorded automatically by an ambulatory BP monitor (TM2421, A&D, Tokyo) to give 96 measurements a day. [Results] The mean BP (MBP) in the G group was negatively correlated with PRA (r=-0.551, p<0.05) and with PAC (r<-0.440, NS). There was a negative correlation between incidence showing abnormal BP (IABP, systolic BP;SBP above 140 mmHg, diastolic BP:DBP above 90 mmHg) and PRA in the G group (SBP, r=-0.528, p<0.05, DBP, r=-0.589, p<0.05). However, there was no correlation between the IABP and PAC in either group. There was a correlation between IABP and the urinary protein level (SBP, r=0.787, p妊婦における24時間自動血圧計を用いた交感神経系が血圧ならびに血圧の夜間下降に及ぼす彩響に関する検討(一般演題:ポスター)

The study group consisted of pregnant women at 20 weeks or more gestation with gestosis (G group;12 cases with hypertension, 10 cases without hypertension) and 23 women without gestosis (N group). [Results] The night dip (ND) of the mean blood pressure (MBP) in the hypertension group was lower than that of the H group (3.4±6.3 mmHg, 8.7±5.6 mniHg, mean±SDf respectively, p<0.05). There was a negative correlation between the MBP and urinary adrenaline (UA) level (r=-0.686, p<0.001) in the G group. The degree of ND of the MBP was significantly correlated with the urinary noradrenaline (NA) level in the G group (r=0.534, p<0.05). Incidence showing abnormal BP (IABP, the systolic BP;SBP above 140 mmHg and the diastolic BP; DBP above 90 mmHg) a day were negatively correlated with UA level in the G group (r<-0.687, p<0.01, r=-0.732, p<0.001). The serum NA level at 6:00 am in the hypertension group tended to be negatively correlated with IABP during nighttime (SBP, r*-0.56; DBP, r=-0.69, NS) and at 9:00 am with IABP (DBP) during daytime (r<-0.752; p<0.05). [Conclusions] The fact that the ND of BP in the G group was not associated with sympathetic nerve activity suggests that the ND might be regulated by some other mechanisms. The MBP was negatively correlated with the UA level in the G group. The serum NA level at 6:00 am tended to be negatively correlated with the IABP during the night and at 9:00 am with the IABP (DBP) during the day. These results suggest that the activity of sympathetic nerve system might be inhibited according to the worsen of gestosis. Pulse rate was related to the sympathetic nerve., 日本妊娠中毒症学会, 日本語40 産婦人科乳房外来における穿刺吸引細胞診

周産期心筋症は、妊娠中から産後にかけて突然の心不全をきたす、妊産婦死亡の原因となる疾患である。本研究では、まず妊娠中の循環動態を観察し、心不全を診断するのに必要な、バイオマーカーや心エコー指標の正常妊娠中・産後の基準値を策定した。次に、正常妊娠と比較して妊娠高血圧症候群や双胎妊娠でどのような循環動態の違いがあるのかを解明し、心不全早期発見のためのバイオマーカーによるスクリーニング方法の一つの提言を行った。本研究成果は、妊娠中・産後の心不全がより簡便に早期発見され、周産期心筋症を発見する一つの端緒を開くものと考えられる。

ABCC11遺伝子は耳垢型決定遺伝子であり、SNP(c. 538G> A, rs17822931)により、乾型、湿型が決定される。今回、このSNP以外の多型である、Δ27(27bp欠失)の頻度を検出した。また、乳がんのエストロゲン非感受性グループと耳垢乾型の頻度の関連性を解析した。市販されているサプリメントAが、腋窩臭を抑制することを推定していたので腋窩臭官能評価をおこない、腋窩(腋臭)を予防できることが判明した。また、ヒトABCC11遺伝子を含むBAC cloneをマウスES細胞ゲノムに挿入したが、ABCC11遺伝子発現は認められなかった。現在もマウスES細胞のtransgeneを作成中である。

1.従来から協力関係にある北海道内の産科施設において、(1)妊娠前・妊娠中の生活習慣、ストレス、ソーシャルサポート、エゴグラムなどの質問調査、(2)母体採血およびDNA抽出・タイピングを継続した。
2.PIH発症におけるいくつかの遺伝子多型要因の検討を行った。それぞれ、アンジオテンシノーゲン遺伝子(AGT)TT型、一酸化窒素合成酵素遺伝子(NOS3)GA+AA型、プラスミノーゲン・アクチベーター・インヒビター遺伝子(PAI-1)4G/5G 多型、Body Mass Index などと交絡も含めて検討したが、本研究期間においては、妊娠高血圧症候群の発症に有意に関連するものは、得られなかった。本研究分野において、あらためて文献レビューを行い、PIH発症のパスウエイおよびそこに関わる遺伝・環境要因を整理し今後の方向性を検討した。
3.妊娠女性に対する介入要因として重要な「妊娠中のストレス」に関する評価指標開発を目的として行った、妊婦を対象としたフォーカスグループインタビュー、個人インタビューから得られた、育児不安に関する項目、経済的問題に関する項目、職場などで先輩女性の理解不足、住居に関する問題、妊娠合計併症に対する不安やそれに対するフォロー体制に関する項目を用いて、妊娠中のストレス評価を試行中である。また、これらのインタビューの手法は、放射線治療目的にて入院中の患者集団における有害事象、QOL、ストレス評価においても応用されている。
