The role of prenatal maternal sex steroid hormones in weight and adiposity at birth and growth trajectories during infancy.

Objective: Intrauterine factors can impact fetal and child growth and may underlie the developmental origins of childhood obesity. Sex steroid hormone exposure during pregnancy is a plausible target because of the impact on placental vascularization, nutrient transportation, bone growth, adipogenesis, and epigenetic modifications. In this study we assessed maternal sex steroid hormones in each trimester in relation to birthweight, neonatal adiposity, and infant growth trajectories, and evaluate sensitive windows of development.

Neurologic Emergencies in Pregnancy.

Neurologic emergencies in pregnancy require prompt evaluation and early, focused intervention to improve neurologic outcomes for the affected person and to avoid further injury. Neurologic events in pregnancy, although rare, present a time of extreme risk of permanent injury for the person who is pregnant. Therefore, obstetric clinicians should be well versed in the risk factors for potential neurologic events and understand the symptoms and events that should prompt evaluation for a neurologic event.

Trends in Reporting of Nuchal Translucency Measurements After the Clinical Introduction of Cell-Free DNA Screening.

Nuchal translucency (NT) measurement in conjunction with serum analytes has been used for first-trimester aneuploidy screening in the United States since 2005. We sought to analyze the trends in reporting of NT measurements to the Nuchal Translucency Quality Review program in all pregnancies beginning after the clinical introduction of cell-free DNA (cfDNA) screening for fetal aneuploidy in 2011. Overall, reported NT measurements decreased 74.

Association between sex steroid hormones and subsequent hyperglycemia during pregnancy.

Objective: Sex steroid hormones may play a role in insulin resistance and glucose dysregulation. However, evidence regarding associations between early-pregnancy sex steroid hormones and hyperglycemia during pregnancy is limited. The primary objective of this study was to assess the relationships between first trimester sex steroid hormones and the subsequent development of hyperglycemia during pregnancy; with secondary evaluation of sex steroid hormones levels in mid-late pregnancy, concurrent with and subsequent to diagnosis of gestational diabetes.
