Intrapartum synthetic oxytocin and breastfeeding: a retrospective cohort study.

Non-pulsatile oxytocin given during labour can negatively affect breastfeeding. The aim of this study was to assess whether intrapartum oxytocin administration has any effect on breastfeeding. Secondly, to assess whether some maternal or neonatal variables influence breastfeeding.

Prediction of adverse pregnancy outcomes by extreme values of first trimester screening markers.

Background: To determine the association between extreme values of first trimester markers and adverse pregnancy outcomes.

Methods: A retrospective cohort study of 916 women who underwent first-trimester combined screening during 2015 was performed. Extreme values of NT, pregnancy-associated plasma protein-A (PAPP-A) and free β-hCG, and their association with adverse pregnancy outcomes were analyzed.
