INTRODUCTION: Triploidy is a lethal chromosomal numeric abnormality, characterized on extra haploid set of chromosomes. It occurs in 2 to 3% of conceptuses and accounts for approximately 20% of chromosomally abnormal first-trimester miscarriages. As such, triploidy is estimated to occur in 1 of 3,500 pregnancies at 12 weeks', 1 in 30,000 at 16 weeks', and 1 in 250,000 at 20 weeks' gestation. CASE REPORT: We present a case of second-trimester triploidy diagnosed prenataly at our center...

AIM: Depression during pregnancy adversely affects both mother and child. As antenatal depression is a predictor of postnatal depression, early detection might prevent postnatal depression. The Edinburgh Postnatal Depression Scale (EPDS) is frequently used during the perinatal period, but the cut-off score during pregnancy has not been verified for the Japanese population. We aimed to clarify the optimal EPDS cut-off score in mid-pregnancy in Japan. METHODS: We recruited pregnant women aged 20 years or older at 12-24 weeks of gestation and those who scored ≥ 9 on the EPDS were invited to participate in this study...

BACKGROUND: Gestational diabetes mellitus (GDM) is increasing partly due to the obesity epidemic. Adipocytokines have thus been suggested as first trimester screening markers for GDM. In this study we explore the associations between body mass index (BMI) and serum concentrations of adiponectin, leptin, and the adiponectin/leptin ratio. Furthermore, we investigate whether these markers can improve the ability to screen for GDM in the first trimester. METHODS: A cohort study in which serum adiponectin and leptin were measured between gestational weeks 6+0 and 14+0 in 2590 pregnant women, categorized into normal weight, moderately obese, or severely obese...

OBJECTIVES: To identify the optimal cut-off points of contingent serum screening excluding nuchal translucency (NT) measurement, to categorize the risk level in the first trimester. METHODS: A prospective database of women undergoing contingent serum screening, without NT measurement, was reviewed. In conventional categorization, the results of first trimester screening were categorized into: high risk (> 1:30) (invasive diagnosis was offered); intermediate risk (1:30-1:1,500) (second trimester screening was needed); and low risk (< 1:1500) (no further test)...

In many developing countries, mothers' awareness remains a challenge despite the scaling up of antenatal care and programs preventing mother-to-child (MTC) HIV transmission. The present study was done in Libreville, Gabon where all antenatal care (delivery included) is free of charge. Here we assessed the timing of antenatal antiretroviral (ARV) prophylaxis initiation, HIV-exposed infants' age at their first postnatal HIV check visit and investigated the association between mothers' awareness or knowledge on their ARV therapy and infants' HIV infection...

INTRODUCTION: Balanced information prior to prenatal diagnosis (PND) aims to help expectant parents to make an informed choice. However, it is important that the information does not increase the expectant parents' psychological distress. The aim was to examine psychological distress among expectant parents, before and after receiving information about PND, to evaluate the possible differences between two different procedures of information giving, and to evaluate the association between satisfaction with the information and psychological distress...

OBJECTIVE: Traditionally, physiological variation in fetal weight is believed to emerge during the latter half of pregnancy. Although recent evidence suggests that crown-rump length (CRL) and nuchal translucency (NT) measured at 11-14 weeks correlate with abnormal fetal growth, findings have been limited by dating accuracy in spontaneous gestations. Therefore, we sought to determine whether CRL or NT measurements correlated with term birth weight (BW) or BW ratio in a cohort of IVF pregnancies, in which the date of conception is precisely known...
