RESUMO
OBJECTIVE: The relationship between FMF and pregnancy outcomes remains unclear. This systematic review and meta-analysis aimed to clarify this association. METHODS: Electronic databases-PubMed, Web of Science, Cochrane, and EMBASE-were searched on 20 December 2022, using specific search terms. Case-control, cohort, and randomized clinical trial studies comparing patients with FMF and healthy controls were considered eligible. We excluded systematic reviews, meta-analyses, case series with fewer than five cases, republished articles without new findings on pregnancy outcomes, studies targeting paternal FMF, and those not published in English. The results were summarized in the form of odds ratios (ORs) and 95% CIs, using a random-effects model. This study was registered in the University hospital Medical Information Network Clinical Trials Registry (Japan) as UMIN000049827. RESULTS: The initial electronic search identified 611 records, of which 9 were included in this meta-analysis (177 735 pregnancies, 1242 with FMF, and 176 493 healthy controls). FMF was significantly associated with increased odds of preterm deliveries (OR, 1.67; 95% CI, 1.05-2.67; I2 = 22%) and insignificantly associated with increased odds of fetal growth restriction (OR, 1.45; 95% CI, 0.90-2.34; I2 = 0%) and hypertensive disorders during pregnancy (OR, 1.28; 95% CI, 0.87-1.87; I2 = 0%). CONCLUSION: FMF was significantly associated with preterm delivery and insignificantly associated with fetal growth restriction and hypertensive disorders. All of the included studies were observational studies. Treatment characteristics were not fully collected from the articles, and further analysis of treatments for FMF in pregnancy is still warranted.

AIM: In 2017, the American College of Cardiology (ACC) re-defined hypertension (HT) as follows: elevated blood pressure (EBP), systolic blood pressure (SBP) 120-129 mmHg and diastolic blood pressure (DBP) <80 mmHg; stage 1 HT, SBP 130-139 mmHg or DBP 80-89 mmHg; and stage 2 HT: SBP ≥140 mmHg or DBP ≥90 mmHg. It is well known that women with stage 2 HT are at higher risk of preeclampsia and have poorer pregnancy and delivery outcomes. While there are few reports on the risk in women with EBP and stage 1 HT, and none from Japan. This study aimed to determine whether women in Japan with EBP and stage 1 HT are at risk of preeclampsia. METHODS: In this single-center retrospective study conducted in Japan, subjects were classified into stage 2 HT, stage 1 HT, EBP, and normal groups based on blood pressure measurements at the time of the first visit before 20 weeks of gestation. Women with a diagnosis of hypertension made before pregnancy were classified into the stage 2 HT group. We compared pregnancy and delivery outcomes, such as preeclampsia, between groups. RESULTS: A total of 5129 cases (normal, n = 4283; EBP, n = 427; stage 1 HT, n = 303; stage 2 HT, n = 116) were included. Preeclampsia incidence rates were 2.7%, 5.6%, 10.6%, and 21.6%, respectively. The adjusted OR (95% CI) for preeclampsia incidence were 2.90 (1.81-4.66), 5.90 (3.87-9.20), and 13.80 (7.97-24.0), respectively. CONCLUSIONS: Women with EBP and stage 1 HT are at high risk of preeclampsia, similar to those with stage 2 HT.

AIM: In March 2021, the Japanese Ministry of Health, Labour and Welfare revised the optimal gestational weight gain standards. In this study, we examined whether this revision affected gestational weight gain and low birth weight rates. METHODS: We analyzed the records of singleton pregnant women who underwent checkups from their 1st trimester and delivered at our institute after 37 weeks between 2020 and 2021 (before the revision) and between 2022 and 2023 (after the revision). Pregnancy outcomes were assessed in the following four groups stratified by pre-pregnancy body mass index (BMI): underweight (BMI: <18.5 kg/m2), normal-weight (BMI: 18.5-24.9 kg/m2), overweight (BMI: 25-29.9 kg/m2), and obese (BMI: ≥30 kg/m2). Leaflets on the optimal gestational weight gain standards for each group were distributed to all pregnant women at the first prenatal checkup. RESULTS: In each group, gestational weight gain did not change before and after the revision, with the corresponding values of 10.8 kg and 11.1 kg in the underweight (p = 0.94), 10.7 kg and 10.4 kg in the normal weight (p = 0.14), 9.7 kg and 9.2 kg in the overweight (p = 0.32), and 7.4 kg and 6.7 kg in the obese (p = 0.44) groups. Furthermore, the prevalence of low birth weight did not decrease in all groups. CONCLUSIONS: No significant differences in gestational weight gain or low birth weight were observed after the revision of the 2021 gestational weight gain recommendations. Merely distributing leaflets to pregnant women may not be sufficient to improve gestational weight gain or reduce low birth weight rates.
RESUMO
AIM: This study aimed to determine the weight gain during pregnancy that minimizes the predicted probability of various perinatal adverse events according to the pre-pregnancy body mass index (BMI) and make recommendations for optimal weight gain in Japan. METHODS: The Japan Society of Obstetrics and Gynecology perinatal database for 2015-2017 was used. From the 719 723 deliveries included in this database, parturients with underlying diseases or missing data were excluded, and 419 114 deliveries were analyzed. A questionnaire survey was also conducted to weigh each perinatal adverse event. For each of the nine outcomes, a restricted cubic spline model was made to estimate the association between the "expected gestational weight gain at 40 weeks" and the outcome risk. RESULTS: Since the classes of medical facilities were generally the same, weights were assigned according to the mean of the questionnaires rather than by the class of the facility. For each pre-pregnancy BMI, the weight gains during pregnancy that minimized the predicted probability of various adverse perinatal events were 12-15, 10-13, 7-10, and upper limit of 5 kg for the underweight, normal-weight, obese 1, and obese ≥2 groups, respectively. CONCLUSIONS: The weight gain during pregnancy that minimizes the predicted probability of various perinatal adverse events according to the pre-pregnancy BMI was established.

BACKGROUND: Postpartum hemorrhage is the leading cause of maternal death and severe maternal morbidity worldwide. Previous studies have reported the importance of multidisciplinary treatment approaches for postpartum hemorrhage; however, only a few studies have shown a clear improvement in maternal outcomes. Therefore, this study aimed to investigate the efficacy of a call system for postpartum hemorrhage in a tertiary emergency facility for rapid multidisciplinary treatment and its effect on maternal outcomes. METHODS: This single-center retrospective cohort study included patients transferred to our hospital due to postpartum hemorrhage between April 1, 2013, and March 31, 2019. The primary outcome was mortality, and the secondary outcomes were morbidity (duration of hospital stay, duration of intensive care unit stay, admission to the intensive care unit, respirator use, duration of ventilator support, acute kidney injury, transfusion-associated circulatory overload/transfusion-related acute lung injury, hysterectomy, composite adverse events, blood transfusion initiation time, blood transfusion volume, and treatment for postpartum hemorrhage). An in-hospital call system implementation commenced on April 1, 2016. The study outcomes were compared 3 years before and after implementing the call system. RESULTS: The blood transfusion initiation time and duration of hospital stay were significantly shortened after implementing the call system for postpartum hemorrhage. No maternal deaths were observed after implementing the system. CONCLUSIONS: Implementing call systems specialized for postpartum hemorrhage in tertiary emergency facilities may improve maternal outcomes.

OBJECTIVES: We aimed to clarify the accuracy of pregnant women's knowledge and understanding regarding infectious disease screening in early pregnancy and clarify the roles that should be played by health care providers in promoting the health of pregnant women and their children. METHODS: A cross-sectional questionnaire survey was conducted in 25 hospitals across Japan from May 2018 to September 2019. We compared the agreement rates regarding screening results for hepatitis B virus (HBV), hepatitis C virus (HCV), syphilis, human T-cell leukemia virus-1 (HTLV-1), and cervical cytology in the medical records and understanding of their results by pregnant women. We then investigated whether participants had knowledge regarding the risk of mother-to child transmission in these diseases and factors associated with their knowledge. RESULTS: We enrolled 2,838 respondents in this study. The rates of agreement for HBV and cervical cancer screening related to human papillomavirus infection were "substantial," those for syphilis was "moderate," and those for HCV and HTLV-1 were "fair," according to the Kappa coefficient. The rate of knowledge regarding mother-to-child transmission of syphilis was highest (37.0%); this rate for the other items was approximately 30%. Increased knowledge was associated with higher educational level and higher annual income. CONCLUSIONS FOR PRACTICE: Pregnant women in Japan had generally good levels of understanding regarding their results in early-pregnancy infectious disease screening. However, they had insufficient knowledge regarding mother-to-child transmission of these diseases. Health care providers should raise awareness in infectious disease prevention among pregnant women and the general public, providing appropriate measures and implementing effective perinatal checkups and follow-ups for infectious diseases.

BACKGROUND: To investigate whether false-positive early gestational diabetes mellitus (GDM) women can be managed similarly as normal glucose tolerance (NGT) women. METHODS: This retrospective study was conducted at a tertiary care center in Japan. Pregnancy and neonatal outcomes of 67 singleton pregnancies with false-positive early GDM and 1774 singleton pregnancies with NGT who delivered after 22 weeks of gestation were compared. GDM was diagnosed according to the International Association of Diabetes and Pregnancy Study Groups (IADPSG) criteria (patients having one or more of the following: fasting plasma glucose ≥ 92 mg/dL and a 75 g oral glucose tolerance test (OGTT) value ≥ 180 mg/dL at 1 h, or ≥ 153 mg/dL at 2 h). Pregnant women diagnosed with GDM in early pregnancy who did not meet the diagnostic criteria on the second OGTT were defined as having false-positive early GDM. Women with false-positive early GDM did not receive any therapeutic intervention during gestation. RESULTS: Maternal age, pre-pregnancy body mass index, and gestational weight gain were significantly higher in the false-positive GDM group than in the NGT group. No significant differences were found in pregnancy outcomes, including gestational age, birth weight, large for gestational age rate, and cesarean delivery rate. Except for a higher neonatal hypoglycemia rate in the false-positive early GDM group, no significant differences were found in neonatal outcomes. CONCLUSIONS: There were no clinically significant differences between early GDM false-positive women exhibiting GDM patterns only during early pregnancy and NGT women. False-positive early GDM women can be managed similarly as NGT women, suggesting that World Health Organization diagnostic guidelines, applying the IADPSG criteria during early pregnancy, need revision.

BACKGROUND: Placental abruption (PA) with intrauterine fetal death (IUFD) is associated with a high risk of postpartum hemorrhage (PPH) resulting from severe disseminated intravascular coagulation (DIC). Therefore, blood products that are sufficient for coagulation factor replacement must be prepared, and delivery should occur at referral medical institutions that are equipped with sufficient blood products and emergency transfusion protocols. We retrospectively reviewed the records of patients with PA and IUFD (PA-IUFD) to identify possible factors that may indicate the need for early blood transfusion and investigated whether the Japanese scoring system for PPH can be applied in such cases. METHODS: We used a database of 16,058 pregnant patients who delivered at Yokohama City University Medical Center between January 2000 and February 2016. Thirty-three patients were diagnosed with PA-IUFD before delivery and categorized into two groups-blood transfusion and non-transfusion-to compare the maternal characteristics and pregnancy outcomes. RESULTS: In patients with PA-IUFD, the transfusion group exhibited significantly more blood loss; lower fibrinogen levels and platelet counts; higher levels of fibrin degradation products (FDP), D-dimer, and prothrombin time; and a tendency for tachycardia on admission, compared to the non-transfusion group. Many patients in the transfusion group had normal fibrinogen levels on admission but later displayed markedly decreased fibrinogen levels. The Japan Society of Obstetrics and Gynecology (JSOG) DIC score was significantly higher in the transfusion than in the non-transfusion group. CONCLUSIONS: In PA-IUFD, the fibrinogen level, platelet count, D-dimer, FDP, heart rate, and JSOG DIC score on admission may indicate the need for blood transfusion. However, even with normal fibrinogen levels on admission, continuous monitoring is indispensable for identifying progressive fibrinogen reductions in patients with PA-IUFD.

Singleton pregnant women with gestational diabetes mellitus (GDM) are at an increased risk of adverse maternal and neonatal outcomes. Multiple pregnancies are associated with increased risks of perinatal complications; however, the impact of GDM on maternal and neonatal outcomes in multiple pregnancies is unknown, and there are currently few reports on GDM status in twin pregnancies. This study aimed to compare the background and perinatal outcomes between Japanese twin pregnancies with and without GDM at a perinatal center in Japan. Additionally, the clinical course of GDM was investigated. In this retrospective cohort study, women with twin pregnancies underwent GDM screening at Yokohama City University Medical Center from January 2011 to December 2016. Overall, 307 twin pregnancies were divided into GDM (47 cases, 15.3%) and non-GDM (260 cases, 84.7%) groups. GDM-associated pregnancy complications, GDM status, and pregnancy outcomes were ascertained. Women with GDM were older and had a higher pre-pregnancy body mass index than those without GDM. Glycemic control was good in all patients, and there was no difference in delivery outcomes between the two groups. Gestational weight gain was lower in pregnant women with GDM (+8.0 kg) than in those without GDM (+11.8 kg), suggesting the impact of strict nutritional guidance on twin pregnancies with GDM. In conclusion, twin pregnancies with GDM did not have different delivery outcomes compared to those without GDM. To manage twin pregnancies with GDM, this study suggests that it is important to monitor patients' weight and blood glucose levels.

AIM: To investigate how an extremely prolonged second stage of labor of 12 h or more affects maternal and neonatal outcomes. MATERIAL AND METHODS: This retrospective cohort study included nulliparous, pregnant women with 37 + 0 to 41 + 6 weeks of gestation whom vaginal delivery was attempted at the Yokohama City University Medical Center between 2014 and 2018. RESULTS: In 446 cases of the prolonged second stage of labor, there were 296 women (66%) in the 2- to 6-h second stage of labor group, 112 women (25%) in the 6- to 12-h group, and 38 women (8.5%) in the 12-h or longer group. The longer the second stage of labor, the more significant was the increase in the rates of augmentation of the delivery, emergency cesarean delivery, and operative vaginal delivery. Even in the 12 h or longer group, 82% were able to have vaginal delivery. The 6- to 12-h group had a significant increase in third- or fourth-degree perineal lacerations compared to the 2- to 6-h group (aOR 8.12 [95% CI 1.55-42.6]). Clinical chorioamnionitis was significantly increased in the 12 h or longer group (aOR 4.88 [95% CI 1.62-14.8]). In terms of neonatal outcomes, comparison between the three groups showed no significant difference. CONCLUSION: With an extremely prolonged second stage of labor, maternal complications involved a significant increase in severe perineal lacerations and chorioamnionitis; however, there was no increase in adverse outcomes for neonates. It was not possible to conclusively determine if the duration of the second stage is acceptable.

This study aimed to clarify the appropriate management of gravid uterus incarceration through a retrospective analysis of 10 women with an incarcerated gravid uterus who delivered at our hospital between 2000 and 2019. The incidence of an incarcerated gravid uterus was one in 2000 cases. Nine cases were diagnosed during pregnancy (15-30 gestational weeks) and one during caesarean section (performed at 37 gestational weeks on suspicion of placenta previa). Two women underwent manual reduction at 19 and 20 gestational weeks, respectively; the procedure failed in one case, and intrauterine foetal death occurred after the procedure. Among the remaining eight cases, spontaneous reduction was observed in three women at 31, 33 and 34 gestational weeks, respectively. The prevalence of incarcerated gravid uteri may be higher than that previously reported, cases may more likely recover spontaneously, and spontaneous reduction could occur in the third trimester.Impact StatementWhat is already known on this subject? Gravid uterine incarceration is a rare condition that occurs in one in 3000-10,000 cases. In addition, previous reports have suggested that manual reduction should not be attempted after the 20th week of gestation.What do the results of this study add? In the current study, the incidence of an incarcerated gravid uterus was one in 2000 cases, higher than that mentioned in previous reports. In addition, spontaneous reductions occurred in three of eight cases in which manual reductions were not performed at 31, 33 and 34 gestational weeks.What are the implications of these findings for clinical practice and/or further research? The prevalence of an incarcerated gravid uterus and the rate of spontaneous reduction might be higher than those reported in previous studies, and spontaneous reduction could occur in later gestational weeks than that previously reported. Further prospective multicentre studies are necessary to establish new evidence for the management of gravid uterine incarceration.

BACKGROUND: In 2010, the International Association of Diabetes and Pregnancy Study Group (IADPSG) proposed new criteria indicating that gestational diabetes mellitus (GDM) can be diagnosed if the fasting threshold of ≤92 mg/dL, 1-h threshold of ≤180 mg/dL, or 2-h threshold of ≤153 mg/dL are exceeded during the 75-g 2-h oral glucose tolerance test (OGTT) performed at 24-28 weeks of gestation. The World Health Organization (WHO) recommends using the proposed diagnostic threshold values of the IADPSG to diagnose GDM; however, it does not limit the timing of the 75-g OGTT. Since 2010 in Japan, GDM has been diagnosed using the same criteria as that proposed by the WHO. However, neither the JSOG nor the WHO has provided any evidence that it is appropriate to use a threshold beyond the range recommended by the IADPSG. METHODS: This was a single-centre retrospective study based on the medical records and delivery registry database of our centre. We included women who underwent a 50-g glucose challenge test (GCT) with results < 140 mg/dL at 24-28 weeks of gestation and subsequently underwent a 75-g OGTT after 29 weeks of gestation with abnormal glucose tolerance suspected based on clinical findings. The reference values for the 75-g OGTT followed the IADPSG criteria. Subjects were classified into the normal glucose tolerance (NGT) group and the GDM group. The type of delivery and neonatal outcomes of the two groups were compared. A multivariable analysis was performed to match the backgrounds of both groups. RESULTS: In total, the NGT and GDM group comprised 189 and 49 women, respectively. Emergency caesarean delivery rates were similar in the GDM and NGT groups (10.6 and 12.2%, respectively; adjusted odds ratio [OR], 1.25; 95% confidence interval [CI], 0.43-3.64; p = 0.74); however, the elective caesarean delivery rate was higher in the GDM group than in the NGT group (16.3 and 5.3%, respectively, adjusted OR, 3.60; 95% CI, 1.27-10.19; p = 0.01). No significant differences were observed in other maternal and neonatal outcomes between both groups. CONCLUSION: Although a diagnosis of GDM during the third trimester does not improve pregnancy outcomes, it increases the elective caesarean delivery rate.

AIM: During pregnancy, the ovarian endometrioma generally decreases in size and occasionally ruptures. We evaluated (1) whether and how ovarian-endometrioma size changes from the first trimester to the postdelivery period, and (2) the type of endometrioma more likely to rupture during pregnancy. METHODS: During an 18-year period (2000-2018), ultrasound in the first trimester revealed ovarian endometrioma in 149 pregnant women at our tertiary institute. Among these, we subjected 138 endometriomas in 145 patients to expectant management (wait-and-watch approach during pregnancy). We compared the cyst sizes in the first trimester and the postdelivery period, and defined a >1 cm diameter size-change as a significant increase/decrease. We analyzed four patients with rupture and characterized the predictors of rupture. RESULTS: A comparison of cyst sizes in the first trimester and the postdelivery period revealed that the size of 94 (68%), 37 (27%), and 7 ovaries (5.0%), respectively, decreased, remained unchanged, and increased; in 56 ovaries (40%), apparent cysts were no longer present. Of the 145 patients, four (2.8%) required emergency surgery for cyst rupture. Adhesion to the surroundings, an increase in cyst size, large size (diameter of ≥6 cm), and compression due to the enlarged uterus in late pregnancy were factors clinically related to rupture. CONCLUSIONS: Approximately two-thirds of ovarian endometriomas decreased in size during pregnancy (40% disappeared), 27% remained unchanged, and only 5% increased in size. However, 2.8% of pregnant women with endometrial cysts experienced rupture. We characterized risk factors for rupture; however, clinical application requires further evaluation.

AIM: In 2010, the Japan Society of Obstetrics and Gynecology (JSOG) changed the diagnostic criteria for gestational diabetes mellitus (GDM) to follow the International Association of Diabetes and Pregnancy Study Group (IADPSG) criteria. As a result, many pregnant women with mildly impaired glucose tolerance (IGT) were newly diagnosed with GDM. This study aimed to verify the effects of interventions in pregnant women with mild IGT who were newly diagnosed with GDM based on the present JSOG criteria. METHODS: We defined mild IGT as a degree of IGT that would be diagnosed as GDM according to the present but not the previous JSOG criteria. We compared pregnancy and delivery outcomes in women with mild IGT who delivered a singleton at 22 weeks of gestation or later, between 2000 and 2009 (untreated group, n = 503) versus between 2011 and 2017 (treated group, n = 781). RESULTS: The incidence of GDM-related composite complications such as macrosomia, shoulder dystocia, neonatal hypoglycemia, neonatal hyperbilirubinemia, and neonatal respiratory distress syndrome was comparable in the untreated and treated groups (10.1% vs. 11.9%, p = 0.11). The pregnancy outcomes were also comparable, except for infant birth weights, which were lower in the treated group than in the untreated group (3014 g vs. 3094 g; p = 0.02). CONCLUSIONS: Pregnancy outcomes were not affected by the interventions in pregnant women with mild IGT.

AIM: This study aimed to clarify how the COVID-19 pandemic impacts psychological stress levels in postpartum women in Yokohama, Japan. METHODS: We retrospectively compared the rates of positive screening tests for postpartum depression (Edinburgh Postnatal Depression Scale score of 9 or more or self-injury factors) and liaison/psychiatric intervention rates between pre-pandemic and pandemic groups of postpartum women who delivered a live birth at our tertiary perinatal center in Yokohama, Japan between January 2019 and May 2020. Those whose postpartum health screening was performed in 2019 (March-June 2019) were considered the pre-pandemic group, and those whose screening was performed between March and June 2020 were considered the pandemic group. Adjustments were made for maternal background, pregnancy, and delivery outcomes, including a history of psychiatric disorders, complications, preterm delivery, NICU admission, and maternal postpartum complications, and the data were analyzed using a logistic regression analysis. RESULTS: Postpartum health screenings were performed on 339 women before the pandemic and 279 women during the pandemic. Positive screening rates for postpartum depression did not change before and during the pandemic (adjusted odds ratio 1.48, 95% confidence interval 0.885-2.46). CONCLUSIONS: There was no apparent increase in maternal psychological stress due to the COVID-19 pandemic in Yokohama, Japan. Postpartum women responded differently in settings with varied levels of disease severity and social restrictions.

AIMS: To investigate whether the Institute of Medicine (IOM) guidelines for optimal gestational weight gain (GWG) in twin pregnancies are applicable to Japanese women. METHODS: This was a retrospective study involving women who delivered full-term twins at our tertiary center diagnosed with a normal prepregnancy body mass index. The women were divided into two groups, according to the optimal GWG recommended by the IOM (16.8-24.5 kg): the adequate GWG (AGWG) group with GWG meeting the guidelines and the low GWG (LGWG) group with GWG below the guidelines. Next, the women were divided into two groups according to birthweight: a group with both twins born appropriate for gestational age (AGA group) and a group with one or both twins born small for gestational age (SGA group). Their GWG as well as their pregnancy outcomes were compared. RESULTS: A total of 265 women were included. The AGWG group had a significantly higher proportion of hypertensive disorders of pregnancy than the LGWG group. There was no significant difference in the proportion of women with both twins born AGA or the rate of admission to the neonatal intensive care unit. Meanwhile, the median GWG in the AGA group was 13.6 kg, which was significantly higher than 12.0 kg in the SGA group. And even the median GWG in the AGA group was below the lower limit of the IOM guidelines. CONCLUSION: The optimal GWG for Japanese women with twin pregnancies may be below the IOM guidelines.

AIM: In Japan, the criteria of the latent and active phases of the first stage of labor have not been decided. The Japan Society of Obstetrics and Gynecology (JSOG) Perinatal Committee conducted a study to construct a spontaneous labor curve in order to determine the point of onset of the active phase. METHODS: The participants were women who had spontaneous deliveries at four health facilities in Japan between September 1, 2011, and September 31, 2019. Spontaneous delivery was defined as the spontaneous onset of labor at term (37 weeks, 0 days to 41 weeks, 6 days) with vaginal delivery of a mature fetus in a cephalic position without uterotonic agents or epidural analgesia. The time points for each "cm" of dilation were collected starting from the time of full dilation retrogradely. The relationship between time since labor onset and cervical dilation was expressed as a curve using a smoothing B-spline. RESULTS: A total of 4215 primiparous and 5266 multiparous women were included in this study. The spontaneous labor curve showed that in both primiparous and multiparous women, labor progress was slow until 5 cm cervical dilation, accelerating between 5 and 6 cm dilation, and steadily progressed after 6 cm dilation. CONCLUSION: We propose that the active phase of the first stage of labor be defined as starting at 5 cm dilation of the cervix, and that it be divided into an acceleration phase (5-6 cm dilation) and a maximal phase (>6 cm dilation).

To estimate pregnancy complications in women newly diagnosed with gestational diabetes mellitus (GDM) according to the new International Association of Diabetes and Pregnancy Study Groups (IADPSG) criteria and verify the validity of introducing the IADPSG criteria in Japan. This retrospective study included data from women with singleton delivery at 22 weeks or later at a tertiary hospital during 2000-2009. We compared pregnancy outcomes between women who would now be diagnosed with GDM according to the IADPSG criteria but not by the old JSOG criteria (IGT group, n = 503) and women with normal glucose tolerance according to both the criteria (NGT group, n = 2,789). Multivariate analysis was performed and adjusted for background factors. Maternal age at delivery and pre-pregnancy BMI were significantly higher in the IGT group than in the NGT group, while gestational weeks at delivery did not differ between the groups. No difference was observed in the rates of GDM-related composite complications (defined as cases with at least one of the following: macrosomia, shoulder dystocia, neonatal hypoglycemia, neonatal hyperbilirubinemia, or neonatal respiratory distress syndrome) at 11.9% and 8.8% (adjusted odds ratio (OR) 1.30, 95% confidence interval (CI) 0.90-1.87, p = 0.16). Pregnancy outcomes did not differ significantly between the IGT and NGT groups, except for frequencies of total neonatal admissions at 10.5% and 7.1%, respectively (adjusted OR 1.55, 95% CI 1.12-2.13, p < 0.01).

AIM: Reports on pregnancy and delivery in women with Turner syndrome (TS) in Japan are limited to case reports, and the current situation remains unclear. Therefore, this study aimed to clarify the current situation of pregnancy and delivery in women with TS in Japan. METHODS: Our study comprised primary and secondary surveys and we included perinatal centers approved by the Ministry of Health, Labor and Welfare. RESULTS: A total of 24 cases from 19 facilities were reported, and we obtained individual information for 20 cases from 16 facilities. Of these 20 patients, 13 (65%) had become pregnant via oocyte donation. Three of these patients had received oocyte donation in Japan, while the other 10 had received donations in foreign countries. The other seven patients became pregnant with their own oocyte, with spontaneous menarche. Live babies were delivered by 18 patients, while an induced abortion was required at 18 weeks of gestation in one patient and an intrauterine fetal death from an unknown cause was detected at 38 weeks of gestation in another patient. Cesarean section was performed in 14 patients, with the most frequent indication being cephalopelvic disproportion. The rate of implementation of screening for complications related to TS was low, suggesting insufficient cooperation between facilities responsible for TS treatment, infertility and pregnancy and delivery management. CONCLUSION: To improve pregnancy outcomes in women with TS, improved cooperation between facilities and laws regarding oocyte donation in Japan are needed.

BACKGROUND: This is the first retrospective report of pregnancy outcomes after exposure to adalimumab treatment in Japan. METHODS: Using the AbbVie safety database, we analyzed pregnancy outcome data from patients who received adalimumab treatment from April 16, 2008, to May 15, 2017. RESULTS: Data were extracted retrospectively for 74 pregnancies in 73 patients. More than half of the patients included in the study received adalimumab for the treatment of Crohn's disease (37.8%) or ulcerative colitis (20.3%), while 9.5% received adalimumab for rheumatoid arthritis. Of the 53 pregnancies with available outcome data, 45 newborns (45/53 [84.9%]) were delivered. Of these births, 30 were full-term, 2 were preterm, and 13 were unknown. Apgar scores were available for 11 of the 16 newborns whose mothers were exposed to adalimumab in the third trimester; all scores were within the normal range. Low birth weight was observed in 5 infants out of the 30 full-term deliveries. There were also 5 miscarriages (5/53 [9.4%]), 2 induced abortions (2/53 [3.8%]), and 1 stillbirth (1/53 [1.9%]). Eight maternal adverse events were observed in 5 pregnancies; no serious adverse events occurred. CONCLUSION: Although safety concerns were inconclusive, these data do not report additional risk to pregnancy outcomes with adalimumab exposure.
