BACKGROUND Data on extreme obesity and placental abruption are scarce. This study aimed to determine the association between pre-pregnancy weight and placental abruption and whether pregnancy weight gain impacts this risk. METHODS We used the Missouri maternally linked cohort files (years 1989-1997). Analyses were restricted to singleton live births (n = 461 729). Maternal body mass index (BM...

Our laboratory has demonstrated that Yorkshire placentae increase in size and surface area during the final third of gestation. In contrast, Meishan placental size remains constant during late gestation, but the density of blood vessels at the placental-endometrial interface increases markedly. Preliminary observations from our laboratory suggest that if one of two adjacent Meishan fetuses dies...

BACKGROUND: Recent studies have highlighted the clinical importance of placental weight, as predictors maternal and neonatal morbidity mortality. The index is ratio between weight fetal weight. Placental considered a efficiency indicator. AIM: This study aimed to describe determine correlation with pregnancy outcome. METHODS: used cross-sectional design using primary data obtained from Mitra Se...

The specific role of weight change in the first weeks of gestation in fetal growth has not been fully explored in humans. Our aims were to investigate: (1) the specific association between weight change in the first trimester of pregnancy (WCT1) and size at birth in term pregnancies; and (2) the role of placental weight in this relationship. From 2002 women included in the French EDEN study, 17...

Background Small for gestational age (SGA) refers to newborns whose birth weight is less than the 10th percentile for gestational age. The aim of this study was to provide a comparative assessment of ultrasound placental findings in SGA and normal-weight fetuses in singleton pregnant women. Materials and Methods In...

OBJECTIVE To observe the effects of exogenous insulin on placental, fetal and maternal outcomes in Gestational Diabetes Mellitus (GDM). METHODS After screening and diagnoses(WHO criteria) 30 GDM patients(Group A) were kept on diet control and 39 GDM (Group B) who did not achieve glycemic targets were added subcutaneous insulin. Term placental weight, size, shape, consistency, fibrinoid necros...

The purpose of this study is to present curves of estimated placental growth in twins and to evaluate the relative contribution of gestational age, zygosity, chorionicity, fusion of the placentas, sex of the individual and of the twin pair, site of the umbilical cord insertion, birth order, maternal age, and parity. Perinatal data and placental data were obtained from 6315 live-born twin pairs ...
