Pilot randomised controlled trial comparing the risk of neonatal respiratory distress in elective caesarean section at 38 weeks' gestation following a course of corticosteroids versus caesarean at 39 weeks.

Introduction: The objective of this study was to compare neonatal respiratory morbidity and rate of emergency caesarean section between elective caesarean sections at 38 gestational weeks following a course of corticosteroids and planned caesarean sections at 39 gestational weeks.

Material And Methods: This was a multicentre randomised controlled trial. The study was conducted between 2007 and 2013 in level 2 and 3 maternity units in France.

Benefits of cord blood collection in the prevention of post-partum hemorrhage: a cohort study.

Objective: The aim of this study was to assess the benefit of umbilical cord drainage through cord blood collection (CBC) for the prevention of post-partum hemorrhage (PPH).

Methods: This is a retrospective cohort study based on data collected prospectively including all vaginal delivery of singletons pregnancies after 37 weeks of gestation between July 2011 and May 2013 at the Strasbourg Teaching Hospital. We performed a univariate comparison of PPH risk factors with χ(2) tests and then we built multivariate logistic regressions to predict PPH, severe PPH (>1000 cc), retained placenta over 30 min and manual removal of the placenta.

Predictive value of cardiovascular parameters in stages 1 and 2 of twin-to-twin transfusion syndrome.

Objective: The Quintero staging of twin-to-twin transfusion syndrome (TTTS) does not include a comprehensive cardiovascular assessment. The aim of this study is to assess the predictive value of the myocardial performance index (MPI) and the Children's Hospital of Philadelphia (CHOP) score on recipient survival in Quintero stages 1 and 2 TTTS.

Methods: The cohort study was based on prospectively collected data between May 2008 and February 2013 in a population of stages 1 and 2 TTTS.

Prediction of spontaneous preterm delivery in the first trimester of pregnancy.

Objective: To develop a model for predicting premature delivery before 37 weeks' gestation based on maternal factors, obstetric history and biomarkers in the first trimester of pregnancy.

Study Design: Cohort study based on data collected prospectively between 1 January 2000 and 30 November 2011. Multivariate logistic regression was used to construct a model of the risk of premature delivery.
