Although gestational hypertension (GH) is a well-known disorder, gestational proteinuria (GP) has been far less emphasized. According to international criteria, hypertensive disorders of pregnancy include GH but not GP. Previous studies have not revealed the predictors of progression from GP to preeclampsia or those of progression from GH to preeclampsia. We aimed to determine both sets of predictors. A retrospective cohort study was conducted with singleton pregnant women who delivered at 22 ge

Perinatal mortality was more likely to occur in women with glucose intolerance. In the Japanese infants that succumbed to perinatal mortality, fetal anomaly was more prevalent in those born to women with a glucose intolerance than in those born to the general population.

<div><p>Pregnant women with diabetes mellitus (DM) are at high risk for hypertensive disorder of pregnancy (HDP). Women with poor control DM sometimes have heavy-for-dates infants. However, women with HDP sometimes have light-for-dates infants. We aim to clarify the relationship between glycemic control and fetal growth in women with DM and/or subsequent HDP. Of 7893 women gave singleton birth at or after 22 gestational weeks, we enrolled 154 women with type 1 DM (T1DM) or type 2 DM

A predictor of recurrent GDM onset was a score of 2 or 3 positive points on the OGTT during the first pregnancy.

An educational seat belt leaflet was effective in raising the rate of consistent seat belt use during pregnancy, but it did not decrease the rate of motor vehicle accidents. The wearing of seat belts should be promoted more extensively among pregnant women to decrease rates of pregnancy-related morbidity and mortality from motor vehicle accidents.

The capacity to provide therapy for postpartum hemorrhage and obstetrical DIC varied widely among the three groups of institutions.

Among the women thought to have a low risk of VTE during the antepartum period, and especially women who had a vaginal delivery, the actual incidence of VTE might have increased in Japan.

This study aimed to investigate the relationship between gestational diabetes mellitus (GDM) screening methods and GDM incidences. In 2018, a national questionnaire was administered at 231 institutions (56.6%) of all 408 perinatal medical centers in Japan. Of 100,485 women, 2,982 (3.0%) were diagnosed with GDM during their first pregnancy period (FPP) and 7,289 (7.3%) were diagnosed with GDM during their middle pregnancy period (MPP). The proportion of women diagnosed with GDM during FPP and MPP

Since July 2022, obstetrical disseminated intravascular coagulation (DIC) in Japan has been diagnosed based on the new criteria (tentative version), which assesses the main underlying disease, fibrinogen level, and fibrin/fibrinogen degradation products or D-dimer level. In June 2024, the tentative version underwent minor revision and the final version was released. The previous Japanese criteria assessed underlying disease, clinical symptoms, and various laboratory findings. This study aimed to

A cutoff of 78% antithrombin activity at diagnosis of early-onset pre-eclampsia might be used as a predictor of delivery within 7 days.
