BACKGROUND/OBJECTIVES: Vitamin D deficiency is common among pregnant women and since the fetus relies exclusively on maternal supply, deficiency could potentially interfere with fetal development. Vitamin D blood concentrations during pregnancy have been associated with offspring cardio-metabolic health in a few previous studies but the evidence is still inconsistent and only one previous study has followed the offspring into adulthood. The aim of the present study was to investigate the association between maternal serum concentration of vitamin D (25(OH)D) in week 30 of gestation and offspring cardio-metabolic risk factors at 20 years...

Clinical findings and data obtained in animal models indicate that nutrient uptake and exposure to environmental agents during pregnancy may affect fetal/newborn gestational programming thereby resulting in obesity and/or obesity-related disorders in offspring. Human amniotic mesenchymal stem cells (hA-MSCs) differentiate into adipocytes, and are thus a suitable model to investigate adipocyte functions in obesity. The aim of this study was to elucidate the miRNome of hA-MSCs and its contribution to obesity in pregnancy...

This study was carried out to explore associations between assisted reproductive technology (ART) and maternal and neonatal outcomes compared with similar outcomes following spontaneously conceived births. We conducted a retrospective cohort study of pregnancies conceived by ART (N = 2641) during 2006-2014 compared to naturally conceived pregnancies (N = 5282) after matching for maternal age and birth year. Pregnancy complications, perinatal complications and neonatal outcomes of enrolled subjects were investigated and analysed by multivariate logistic regression...

For centuries it has been considered that the due date for delivery in our species is 280 days after the onset of the last menstruation. However, in most cases this statement is not accurate. The main objective of this study was to determine the mean duration of pregnancy in our setting and whether it has experienced changes in recent years. A retrospective, population-based descriptive study was made of 102,169 deliveries assisted in Malaga University Hospital (Malaga, Andalusia, Spain) during the period 1998-2015...

Heart disease, stroke, and kidney failure are leading causes of death worldwide, and hypertension is a significant risk factor for each. Hypertension is less common in women, compared to men, in those younger than 45 years of age. This trend is reversed in those 65 years and older. In the US between 2011-2014, the prevalence of hypertension in women and men by age group was 6% vs 8% (18-39 years), 30% vs 35% (40-59 years), and 67% vs 63% (60 years and over). Awareness, treatment, and control rates differ between genders with women being more aware of their diagnosis (85% vs 80%), more likely to take their medications (81% vs 71%) and more frequently having controlled hypertension (55% vs 49%)...

OBJECTIVE: Superimposed pre-eclampsia (SPE) is resolved only with the termination of the pregnancy. Therefore, the risk prediction and prevention is very important. We aimed to evaluate the characteristics of patients who develop SPE and their controllable risk factors during mid-trimester. DESIGN AND METHOD: A total of 283 pregnant women with chronic hypertension were included for the study. Blood pressure (BP) and body weight were recorded at 10, 20, 24, 28, and 32 weeks of gestation and pregnancy outcomes were evaluated...

Hyperthyroidism can occur during pregnancy and the postpartum period, and the treatment of hyperthyroidism should be considered in the preconception phase. Pregnancy has multiple normal physiologic effects on thyroid hormone, which is a separate process distinct from syndromes such as transient hyperthyroidism of hyperemesis gravidarum. The rationale regarding antithyroid drug use during different stages of pregnancy is reviewed, including the literature regarding adverse neonatal outcomes such as aplasia cutis and methimazole embryopathy in the setting of first trimester maternal methimazole use...
