Timing of Elective Cesarean Section and Neonatal Outcomes in Term Singleton Deliveries: A Single-Center Experience.

Objective: This study aimed to evaluate the timing of elective cesarean sections at 37 to 41 weeks from a tertiary hospital in Japan. The primary outcome was the rate of adverse neonatal outcomes, especially focusing on neonates delivered at 38 weeks of gestation.

Study Design: The study population was drawn from singleton pregnancies delivered following planned cesarean birth at the Fukuda Hospital from 2012 to 2019.

Sleep habits and problems across gestational progress in Japanese women.

Background: Pregnancy-related anatomic, physiologic, and hormonal factors can occur at different stages of pregnancy and affect sleep disturbances. Sleep problems and habits among Japanese women across gestational stages have not been described. This study aimed to elucidate sleep problems, including a high risk of sleep-disordered breathing and sleep habits, among Japanese women across gestational progress, including postpartum.

A quasi-randomized controlled trial of Ninjin'yoeito for the treatment of postpartum anemia and the prevention of postpartum depression.

Aim: To study the effect of Ninjin'yoeito (NYT) on postpartum anemia and on the development of postpartum depression (PPD).

Methods: In this prospective, single-center, open-label, quasi-randomized controlled trial, patients with anemia 1-2 days postdelivery were randomized to receive either NYT or an oral iron preparation for 4 weeks. The primary endpoint was the hemoglobin (Hb) level.

Knowledge, Attitudes, and Practices Associated with Pertussis Vaccination during Pregnancy: Japan, 2016-2017.

Neonatal pertussis can potentially cause severe complications and even death. Mothers have been most frequently identified as the source of neonatal pertussis. Approximately a dozen countries have implemented pertussis vaccination programs for pregnant women to protect neonates; however, in Japan, this has not been implemented.

One-hour oral glucose tolerance test plasma glucose at gestational diabetes diagnosis is a common predictor of the need for insulin therapy in pregnancy and postpartum impaired glucose tolerance.

Aims/introduction: Gestational diabetes mellitus (GDM) is a risk for adverse perinatal outcomes, and patients with a history of GDM have an increased risk of impaired glucose tolerance (IGT). Here, we carried out two non-interventional and retrospective studies of GDM patients in Japan.

Materials And Methods: In the first study, we enrolled 529 GDM patients and assessed predictors of the need for insulin therapy.

Implications of mercury concentrations in umbilical cord tissue in relation to maternal hair segments as biomarkers for prenatal exposure to methylmercury.

In this study, we investigated how mercury (Hg) concentrations in umbilical cord tissue are correlated with those in biomarkers for prenatal exposure to methylmercury (MeHg). Total Hg (T-Hg) concentrations were measured in 54 mother-child paired samples of maternal blood, umbilical cord tissue, cord blood, and maternal hair segments (1-cm incremental segments from the scalp) collected at parturition. MeHg concentrations were also measured in the cord tissue.

Significance of fingernail and toenail mercury concentrations as biomarkers for prenatal methylmercury exposure in relation to segmental hair mercury concentrations.

Objective: To investigate the appropriateness of mercury (Hg) concentrations in fingernails and toenails at parturition for detecting prenatal exposure to methylmercury (MeHg).

Methods: Total Hg concentrations were measured in 54 paired samples of fingernails, toenails, maternal blood, and maternal hair (1cm incremental segments from the scalp toward the tip) collected at 4th weeks of (early) pregnancy, and the same specimens and cord blood collected at parturition.

Results: Strong correlations were observed between Hg concentrations in fingernails and toenails at early pregnancy (r=0.

Patient with pseudo-retrograde coronary flow in the normal right coronary artery and left circumflex artery: pitfall of retrograde coronary flow to detect coronary artery occlusion.

A 75-year-old lady with hypertension and paroxysmal atrial fibrillation underwent echocardiography to evaluate cardiac function. Transthoracic Doppler echocardiography revealed retrograde coronary flow in the right coronary artery (RCA) and left circumflex artery (LCX). Computed tomographic coronary angiography demonstrated normal but tortuous coronary arteries.

Mercury and docosahexaenoic acid levels in maternal and cord blood in relation to segmental maternal hair mercury concentrations at parturition.

Fish is a major source of harmful methylmercury (MeHg) and beneficial docosahexaenoic acid (DHA) in the developing brain. In this study, we investigated the correlations among maternal and umbilical cord (cord) MeHg and DHA levels at parturition, and mercury (Hg) concentration in 1-cm incremental segments hair samples which grew during gestation representing monthly MeHg exposure levels throughout the period. Whole blood Hg and plasma DHA levels were measured in blood sample pairs collected from 54 mothers at early gestation and parturition, and in cord blood.
