RESUMO
AIM: The aim of this study was to determine the level of awareness of sexual reproductive health and rights (SRHR) among the members of the Japan Society of Obstetrics and Gynecology (JSOG) and identify what the JSOG should do to address SRHR issues. METHODS: A survey questionnaire on JSOG members' awareness of SRHR and what the JSOG should address regarding SRHR was administered in 2019 and 2023. Changes in awareness and the issues that should be addressed from the first to the second survey were evaluated. RESULTS: Seven hundred twelve members responded to the first survey and 506 to the second. Response rates were 4.2% and 2.9%, respectively. There was a significant increase in the number of respondents in the second survey who were aware of sexual reproductive health (SRH) and Sustainable Development Goals (SDGs) compared with the first survey (SRH: 72.6%-86.4%; SDGs: 33.8%-86.4%). Most respondents agreed that SRHR should be promoted. In the first survey, cervical cancer was the most important issue, followed by women's right to self-determination and family planning/contraception. In the second survey, women's right to self-determination was the most important issue. Several free responses highlighted the importance of comprehensive sexuality education as a significant concern for SRHR. CONCLUSION: Between 2019 and 2023, the level of awareness of SRHR among JSOG members increased. The identification of SRHR issues that should be addressed by the JSOG was confirmed. The JSOG and individual obstetricians and gynecologists are responsible for being involved in achieving SRHR.
RESUMO
Advances in perinatal care have improved the prognoses of both mothers and neonates; however, cerebral palsy continues to occur. In this study, we examined methods for the intragestational evaluation of the health of infants who later developed cerebral palsy. A retrospective review was conducted on light-for-dates cases among the 2113 cause analysis reports issued by the Japan Obstetric Compensation System between January 2009 and September 2018. In our examination, we determined that non-stress tests and ultrasonic Doppler tests were used to evaluate fetal well-being. Moreover, we observed cases in which additional testing was not performed even when fetal growth restriction (FGR) was identified. Appropriate management of FGR may help reduce the incidence of cerebral palsy.

AIM: We aimed to grasp the actual working hours of Japanese obstetricians and gynecologists (OB/GYN doctors) as accurately as possible, using the same method of the Ministry of Health, Labour, and Welfare (MHLW). METHODS: The time study targeted OB/GYN doctors working at 10 universities nationwide including Niigata University and 21 institutions which take a role of perinatal care in Niigata prefecture. Working hours per week were calculated based on the following categories: regular and overtime work inside the hospital, work outside the hospital, self-improvement, education, research, and others. Data on weekly working hours were converted to yearly data for analyses. RESULTS: A time study of 10 universities nationwide revealed that 30% of doctors work overtime for more than 1860 h even if they do not include on-call shifts in their working hours. In 21 institutions in Niigata, physicians in Niigata University worked more overtime than other hospitals. It became clear that community health care was supported by dispatching physicians working at university. Furthermore, the results of simulations predicted the pessimistic situation of perinatal medical care in Niigata. CONCLUSIONS: Our study showed the possibility to exist much more OB/GYN doctors who work more than 1860 h of overtime work per year than the data presented by the MHLW based on nation-wide survey in 2019. The fact that the working hours at the side jobs had a great influence on the increase in overtime work of physicians in University was the same result as the report of MHLW published in 2021.

On April 2, 2020, we received a maternal transport from a local city hospital of a pregnant woman (38 weeks and 0 days of gestation) in her 20s, who had the 2019 novel coronavirus disease (COVID-19). We performed an emergency cesarean section with spinal anesthesia because of an abnormal fetal heart rate pattern. A healthy 3106-g male baby was delivered. All the severe acute respiratory syndrome coronavirus 2 polymerase chain reaction tests of nasal and oral discharges, anal swabs and blood samples of the neonate at 9 h, 30 h and 4 days after birth were negative. Because the mother was diagnosed as having COVID-19 pneumonia, the neonate was given formula milk. The mother's nasal discharge samples at 20 and 21 days were negative. The mother first held her baby in her arms on the 22nd day after birth, and they were discharged on the following day. To the best of our knowledge, this is the first report in Japan of a delivery of a baby from a woman infected with COVID-19.

AIM: The Ministry of Health, Labour, and Welfare of Japan proposed a regulation of overtime work as a reform in work style. However, the regulation may deteriorate the quality of medical services due to the reduction in training time. Thus, the study aimed to reveal perceptions in terms of generation gaps in views on self-training and overtime work, among members of the Japan Society of Obstetrics and Gynecology (JSOG). METHODS: A web-based, self-administered questionnaire survey was conducted among members of the JSOG. In total, 1256 respondents were included in the analysis. Data were collected on age, sex, experience as a medical doctor, location of workplace, work style, the type of main workplace, and number of full-time doctors in the main workplace. The study examined the attitudes of the respondents toward overtime work and self-training. The respondents were categorized based on experience as a medical doctor. RESULTS: According to years of experience, 112 (8.9%), 226 (18.0%), 383 (30.5%), 535 (42.6%) doctors have been working for ≤5, 6-10, 11-19, and ≥ 20 years, respectively. Although 54.5% of doctors with ≤5 years of experience expected the regulation on working hours to improve the quality of medical services, those with ≥20 years of experience expressed potential deterioration. After adjusting for covariates, more years of experience were significantly related with the expectation of deterioration in the quality of medical services. CONCLUSIONS: The study revealed a generation gap in the views about self-training and overtime work among obstetricians and gynecologists in Japan.

Neuroimmune interactions are involved in the development of endometriosis. Here, we examined the role of a neuropeptide, calcitonin gene-related peptide (CGRP), and its receptor, receptor activity-modifying protein (RAMP) 1, in growth of endometrial tissues and the formation of blood and lymphatic vessels in a mouse ectopic endometrial transplantation model. Endometrial fragments from donor wild-type (WT) mice transplanted into the peritoneal wall of recipient WT mice grew with increased density of blood and lymphatic vessels. When tissues from RAMP1-deficient (RAMP1-/- ) mice were transplanted into RAMP1-/- mice, implant growth and angiogenesis/lymphangiogenesis were decreased. CGRP was up-regulated in dorsal root ganglia, and CGRP+ nerve fibres were distributed into the implants from the peritoneum. RAMP1 was co-expressed with CD11b (macrophages) and S100A4 (fibroblasts), but did not co-localize with blood vessel endothelial cell marker CD31 or lymphatic vessel endothelial hyaluronan receptor (LYVE)-1. Cultured with CGRP, macrophages up-regulated vascular endothelial growth factor (VEGF)-A, VEGF-C and VEGF-D, whereas fibroblasts up-regulated VEGF-C, but not VEGF-A or VEGF-D, in a RAMP1-dependent manner. CGRP receptor antagonist CGRP8-37 inhibited growth of and angiogenesis/lymphangiogenesis within endometrial tissue implants. These results suggest that RAMP1 signalling is crucial for growth and angiogenesis/lymphangiogenesis in endometrial tissue. Blockade of RAMP1 is a potential tool for the treatment of endometriosis.

Lymphangiogenesis is related to the growth of endometriosis. Here, we examined whether vascular endothelial growth factor (VEGF) receptor 1 (VEGFR1) signaling plays a role in lymphangiogenesis during endometriosis. Endometrial fragments from wild-type (WT) mice transplanted into the peritoneal wall of host WT mice (WTâWT) developed well and displayed enhanced lymphangiogenesis associated with increases in mRNA levels of VEGF-C and VEGF-D. Compared with WT mice, the implant size and lymphangiogenesis were reduced, when endometrial fragments from mice lacking the VEGFR1 tyrosine kinase (TK) domain (TK-/-) were transplanted into host TK-/- mice (TK-/-âTK-/-). Treatment of WTâWT mice with the VEGFR3 kinase inhibitor suppressed the size of implants and lymphangiogenesis. Immunofluorescence analyses demonstrated that VEGF-C and VEGF-D were expressed in both CD11b+ and S100A4+ cells. TK-/-âTK-/- mice had lower numbers of CD11b+ and S100A4+ cells than WTâWT mice. When isolated bone marrow (BM)-derived macrophages or culture murine fibroblasts were stimulated with placental growth factor (PlGF), a specific agonist of VEGFR1, the levels of VEGF-C and VEGF-D were increased in a VEGFR1-dependent manner. These results suggest that VEGFR1 signaling in macrophages and fibroblasts contributes to the growth of endometrial implants and lymphangiogenesis.

AIM: The aim of this study was to investigate the efficacy of T2 star (T2*) mapping in diagnosing ovarian cysts/ tumors. METHODS: Pelvic magnetic resonance examinations including T2*WI were performed before surgery in 35 patients. The region of interest, consisted of a 10 mm2 diameter circle, was set as much as possible inside ovarian tumors/cysts to measure T2*values, and mean T2* values were compared in ovarian cyst/tumor types, retrospectively. Diagnoses of 40 ovarian cysts/tumors were determined by pathological reports, in which 17 were endometriomas, 13 were mature cystic teratomas, 6 were mucinous cystadenomas and 4 were serous cystadenomas. RESULTS: The average T2* values of endometrioma was 56.8 ± 8.7 ms (mean ± SEM), which was significantly lower than that of mucinous cystadenoma (334.2 ± 58.5 ms, mean ± SEM) or serous cystadenoma (237.0 ± 45.4 ms, mean ± SEM). There was no difference in T2* values between endometrioma and mature cystic teratoma (64.1 ± 22.6 ms, mean ± SEM). Receiver operating characteristics curve analysis revealed that optimal cut-off value for differential diagnosis of endometrioma and mucinous or serous cystadenoma was 149.2 ms as T2* value, which has an area under the curve of 0.95 (sensitivity = 92.4%, specificity = 78.6%). CONCLUSION: T2* values were useful to diagnose various types of ovarian cyst/tumor.

BACKGROUND: Infection with Streptococcus agalactiae (Group B streptococcus: GBS) is a significant cause of morbidity and mortality in neonates. Screening for GBS is mainly done by culture-based methods, but a reliable result may take several days to obtain and culture is difficult to perform at institutions without a laboratory. We evaluated an immunochromatography method for rapid detection of GBS-specific surface immunogenic protein (Sip) using anti-Sip monoclonal antibodies. MATERIALS AND METHODS: A total of 377 cervical and vaginal swabs collected during weeks 35-37 of gestation were inoculated into GBS medium F and incubated. Growth of microorganisms and production of red/orange pigment were assessed by observation. Then culture extracts were subjected to immunochromatography and were also inoculated onto chromID Strepto B (STRB) medium, after which isolates were serotyped and characterized by PCR. RESULTS: Of the 377 samples, 54 (14.3%) were positive for GBS by immunochromatography after incubation in GBS medium F. On the other hand, GBS was isolated from 58 (15.4%) of the 377 samples by culture with GBS medium F and STRB medium. Ten of the 58 isolates were non-pigmented and 4 of these were not detected by immunochromatography. The sensitivity, specificity, positive predictive value, and negative predictive value of immunochromatography were 93.1% (54/58), 100% (319/319), 100% (54/54), and 98.8% (319/323), respectively. CONCLUSIONS: Immunochromatography was comparable to culture on STRB medium for detecting GBS, indicating that this method could be used clinically for GBS screening in pregnant women even at small institutions.

AIM: National medical projects are carried out according to medical care plans directed by the Medical Care Act of Japan. In order to improve Japanese perinatal medical care, it is necessary to determine the factors that might influence perinatal outcome. METHODS: Statistical data of births and perinatal deaths were obtained for all municipalities in Japan from 2008 to 2012 from the Portal Site of Official Statistics of Japan (e-Stat). The perinatal mortality of all 349 Japanese secondary medical care zones was calculated. The number of neonatal intensive care units (NICUs), maternal-fetal intensive care units (MFICUs), pediatricians and obstetricians in 2011 were also obtained from e-Stat. Nine secondary medical care zones in two prefectures, Fukushima (7) and Miyagi (2) were excluded to eliminate the influence of the 2011 Great East Japan Earthquake. RESULTS: The 340 secondary medical care zones were divided into three groups according to population size and density: metropolis, provincial city, and depopulation. The number of secondary medical care zones in each group were 52, 168, and 120, respectively. The secondary medical care zones in the depopulation group had fewer pediatricians and significantly fewer NICUs and MFICUs than the metropolis group, but there was no significant difference in perinatal mortality. The only independent risk factor for high perinatal mortality, determined by multivariable analysis, was the absence of an NICU (P = 0.011). CONCLUSIONS: To consider directions in perinatal medical care, planned arrangement and appropriate access to NICUs is indispensable.

BACKGROUND: Moyamoya disease more commonly occurs in young people and women, so patients with this disease may experience pregnancy and delivery. Cesarean section (CS) is often chosen as the mode of delivery for these patients in Japan. No appropriate mode of delivery has yet been established for pregnant women with moyamoya disease in terms of stroke prevention. We have used vaginal delivery under epidural analgesia (EA) in such patients unless CS has been indicated for the maternal or fetal reasons. This study retrospectively analyzed our patients with moyamoya disease who gave birth to confirm the safety of vaginal delivery under EA. METHODS: Twelve consecutive patients diagnosed with moyamoya disease had 14 deliveries at our hospital between September 2004 and January 2013. The incidences of intrapartum stroke were compared between cases of vaginal delivery under EA and CS cases. RESULTS: Ten vaginal deliveries under EA and 4 elective CSs were performed. No intrapartum stroke was observed during either vaginal delivery under EA or CS. Among the patients who underwent vaginal delivery under EA, 1 parturient who experienced 2 deliveries suffered transient ischemic attack during both postpartum periods. All 14 infants were healthy without sequelae. CONCLUSIONS: Vaginal delivery under EA is an option for patients with moyamoya disease, provided that close cooperation with neurosurgeons, obstetricians, and anesthesiologists is assured.

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 2008â through Decemberâ 2012). Women with HI titer < â 1:8 were defined as susceptible to rubella. RESULTS: The seronegative rate was significantly lower in multiparous than primiparous women aged 30â -â 31 years (2.3% [22/967] vs. 4.5% [66/1454], Pâ = â 0.0036), 36â -â 37 years (3.4% [55/1601] vs. 5.7% [79/1389], Pâ = â 0.0030), and overall women (3.8% [350/9315] aged 34.7â ± â 5.2 vs. 5.4% [597/11048] for 33.2â ± â 5.9, Pâ < â 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.

PURPOSE: The purpose of this study is to assess pregnancy outcomes of women treated with a novel neuraminidase inhibitor, laninamivir, during pregnancy. METHODS: A retrospective review of pregnancy outcomes of 112 pregnant women who were given laninamivir for treatment of influenza was performed. Possible adverse events, including miscarriages, preterm birth, foetal malformation and any neonatal morbidity requiring treatment, were assessed. RESULTS: Seventeen, 39, 46 and 10 women were administered a single inhaled dose of 20 or 40 mg of laninamivir at gestational week (GW) 3-11, 12-21, 22-36 and 37 or more, respectively. One (1.8%) of 56 women with laninamivir at GW <22 experienced miscarriage at GW <12. The remaining 111 women gave birth to 111 viable infants but at preterm (GW <37) in nine (8.8%) of 102 women with laninamivir at GW <37. Three (2.7%) of the 111 newborns had malformations: forefoot varus deformity, foot polydactyly and cleft lip in one each born to a mother taking laninamivir at GW 6, 17 and 21, respectively. Five neonates (4.5%) were small for gestational age. Eleven (9.9%), five (4.5%) and no neonates required phototherapy for jaundice, transient respiratory supports for respiratory distress syndrome (n = 2) or transient tachypnoea of the newborn (n = 3), and glucose administration for hypoglycaemia, respectively. CONCLUSIONS: Although this study included a small number of study women and no control women, the results suggested that maternal exposure to laninamivir did not increase the rate of adverse pregnancy and foetal outcomes.

The 'Clinical Guidelines for Obstetrical Practice, 2011 edition' were revised and published as a 2014 edition (in Japanese) in April 2014 by the Japan Society of Obstetrics and Gynecology and the Japan Association of Obstetricians and Gynecologists. The aims of this publication include the determination of current standard care practices for pregnant women in Japan, the widespread use of standard care practices, the enhancement of safety in obstetrical practice, the reduction of burdens associated with medico-legal and medico-economical problems, and a better understanding between pregnant women and maternity-service providers. The number of Clinical Questions and Answers items increased from 87 in the 2011 edition to 104 in the 2014 edition. The Japanese 2014 version included a Discussion, a List of References, and some Tables and Figures following the Answers to the 104 Clinical Questions; these additional sections covered common problems and questions encountered in obstetrical practice, helping Japanese readers to achieve a comprehensive understanding. Each answer with a recommendation level of A, B or C was prepared based principally on 'evidence' or a consensus among Japanese obstetricians in situations where 'evidence' was weak or lacking. Answers with a recommendation level of A or B represent current standard care practices in Japan. All 104 Clinical Questions and Answers items, with the omission of the Discussion, List of References, and Tables and Figures, are presented herein to promote a better understanding among English readers of the current standard care practices for pregnant women in Japan.

OBJECTIVE: To assess adverse fetal outcomes and short-term prognoses of infants exposed to oseltamivir or zanamivir in utero during pandemic (H1N1) 2009 in Japan. STUDY DESIGN: Case series study. We asked the 2611 obstetric facilities in Japan that are members of the Japan Society of Obstetrics and Gynecology to participate, and data were provided from 157 facilities. We evaluated the numbers of pregnancy complications and neonatal abnormalities. RESULTS: We evaluated 624 infants born to 619 women given oseltamivir and 50 infants born to 50 women given zanamivir. Of patients given oseltamivir before gestational week 22, 3 experienced miscarriage and 1 experienced induced abortion. The overall rate of congenital malformations was 2.1% (14/670). In infants exposed during the first trimester, the rate of malformations was 1.3% (2/156) with oseltamivir and 0.0% (0/15) with zanamivir, although in infants exposed during the second and third trimesters, this rate was 2.6% (12/464) with oseltamivir and 0.0% (0/35) with zanamivir. Increased rates of miscarriage in women given antiviral drugs before gestational week 22 (0.9% [3/322]), preterm delivery in women given antiviral drugs before gestational week 37 (5.5% [33/600]), stillbirth (0% [0/670]), neonatal death (0.15% [1/670]), birthweight <2500 g (8.7% [58/670]), small-for-gestational-age infants (8.4% [56/670]), necrotizing enterocolitis (0.0%), intraventricular hemorrhage (0.0%), seizures (0.15% [1/670]), and other transient abnormalities in the neonatal period (4.3% [29/670]) were not observed in those exposed to antiviral drugs before the corresponding episodes or complications. CONCLUSION: Short-term prognoses of infants exposed to oseltamivir or zanamivir in utero were not adversely affected.

AIM: The degree of contamination with radioactive cesium (¹³4Cs and ¹³7Cs) in the human placenta after the accident at Fukushima nuclear power plant (FNP), which occurred on 11 March 2011, has not been assessed. MATERIAL AND METHODS: ¹³4Cs and ¹³7Cs contents were determined in 10 placentas from 10 women who gave birth to term singleton infants during the period between October 2011 and August 2012 using high-purity germanium detectors for gamma ray spectrometry. Five women resided within 50 km of FNP (neighbor group) and gave birth by the end of February 2012, while the other five women resided within 210-290 km of FNP (distant group) and gave birth in July and August 2012. RESULTS: All except one of the 10 placentas contained detectable levels of ¹³4Cs and ¹³7Cs, ranging 0.042-0.742 Bq/kg for ¹³4Cs and 0.078-0.922 Bq/kg for ¹³7Cs. One placenta from a woman living in Tokyo contained 0.109 Bq/kg ¹³7Cs and no detectable level of ¹³4Cs (<0.054 Bq/kg). ¹³7Cs content was more than 0.2 Bq/kg in four and one placentas in the neighbor and distant groups, respectively. CONCLUSION: Degree of contamination of the placenta with radioactive Cs was lower even in women who resided within 50 km of FNP compared to Japanese and Canadian placentas in the mid-1960s after repeated nuclear tests and in northern Italian placentas from 1986-1987 after the Chernobyl power plant accident.

AIM: The aim of our study was: (i) to investigate whether transversus abdominis plane (TAP) block confers additional analgesic effects to epidural morphine alone; and (ii) to determine plasma levels of local anesthetics after TAP block in post-cesarean women. MATERIAL AND METHODS: The subjects were parturients undergoing cesarean section under combined spinal-epidural anesthesia. Morphine (2 mg) was administered to the epidural space close to the end of surgery. Women who desired TAP block were allocated to the TAP group. Women who did not undergo TAP block were allocated to the control group. In the TAP group, 20 mL of either 0.375% ropivacaine or 0.3% levobupivacaine was infused to both sides of the transversus abdominis plane after surgery. All patients were placed on a patient-controlled i.v. analgesia regimen with morphine after surgery. Time to the first morphine request and amount of morphine consumption within 24 h after surgery were compared in patients with and without TAP block. Plasma concentrations of local anesthetics were determined at 15, 30 and 60 min after TAP block. RESULTS: Forty and 54 patients were allocated to the control and TAP group, respectively. The median time to the first morphine request was longer (555 vs 215 min), and the median cumulative morphine consumption within 24 h was lower (5.3 vs 7.7 mg) in the TAP group than in the control group. The maximum median concentrations of ropivacaine and bupivacaine after TAP block were 784 and 553 ng/mL, respectively. CONCLUSION: TAP block had additional analgesic effects to epidural morphine alone.

OBJECTIVE: To clarify the relationship between the number of deliveries and maternal outcomes in Japan, considering the declining birth rate and the evidence that hospitals with few deliveries have medical safety issues. METHODS: Hospitalizations for deliveries were analyzed using the Diagnosis Procedure Combination database from April 2014 to March 2019, after which maternal comorbidities, maternal end-organ injury, medical treatment during hospitalization, and hemorrhage volume during delivery were compared. Hospitals were divided into four groups based on the number of deliveries per month. RESULTS: A total of 792 379 women were included in the analysis, among whom 35 152 (4.4%) received blood transfusions, with a median blood loss of 1450 mL during delivery. Regarding complications, pulmonary embolism was significantly more frequent in hospitals with the lowest number of deliveries. CONCLUSION: Using a Japanese administrative database, this study suggests an association between hospital case volume and the occurrence of preventable complications, such as pulmonary embolisms.

Dermatomyositis (DM) is one of the most common autoimmune rheumatic diseases affecting women of childbearing age. Pregnancy may lead to exacerbation of DM, especially of DM with anti-melanoma differentiation-associated gene (MDA) 5 antibody positivity, leading to a poor obstetric outcome. Here, we report consecutive pregnancies complicated by DM with anti-MDA-5 antibodies. A 32-year-old pregnant woman, gravida 3 para 1, presented with fetal growth restriction. Emergency cesarean section was performed because of non-reassuring fetal status at 28 weeks of gestation. Two days postpartum, the patient's hand eczema had worsened and she was diagnosed with DM with MDA-5 antibody positivity. Immunosuppressive therapy using corticosteroids combined with tacrolimus was immediately started, suppressing the DM symptoms. Eighteen months later, she became pregnant again but was then negative for anti-MDA-5 antibodies while continuing immunosuppressive therapy. During pregnancy, the titer of the antibody gradually increased, peaked in the second trimester and declined to near normal range through the third trimester. A male infant weighing 2418 g was delivered at 38 weeks of gestation. Our case demonstrates that controlling of DM activity using immunosuppressive treatment before and during pregnancy may be beneficial to obstetric outcomes.
