Implementation of fetal clinical exome sequencing: Comparing prospective and retrospective cohorts.

Purpose: We compared the diagnostic yield of fetal clinical exome sequencing (fCES) in prospective and retrospective cohorts of pregnancies presenting with anomalies detected using ultrasound. We evaluated factors that led to a higher diagnostic efficiency, such as phenotypic category, clinical characterization, and variant analysis strategy.

Methods: fCES was performed for 303 fetuses (183 ongoing and 120 ended pregnancies, in which chromosomal abnormalities had been excluded) using a trio/duo-based approach and a multistep variant analysis strategy.

Exercise for pregnant women with pre-existing diabetes for improving maternal and fetal outcomes.

Background: Pregnancies with pre-existing diabetes are high risk, with increased risk of poorer fetal, neonatal, and maternal outcomes. Identifying interventions to improving health outcomes for women with diabetes and their infants is a priority, as rates of diabetes continue to increase.Exercise has been shown to have benefits for non-pregnant individuals with pre-existing type 2 diabetes, such as improving glycaemic control, and reducing visceral adipose tissue and plasma triglycerides.

Exercise for pregnant women with gestational diabetes for improving maternal and fetal outcomes.

Background: Gestational diabetes mellitus (GDM) is associated with both short- and long-term complications for the mother and her baby. Exercise interventions may be useful in helping with glycaemic control and improve maternal and infant outcomes.The original review on Exercise for diabetic pregnant women has been split into two new review titles reflecting the role of exercise for pregnant women with gestational diabetes and for pregnant women with pre-existing diabetes.

[Prenatal screening: the example of Down's syndrome screening].

Prenatal screening for Down's syndrome initially targeted high-risk pregnant women (> 35 years old). However, the vast majority of babies with Down's syndrome are born to younger women (as the majority of babies are born in this age category). It was first discovered that some serum analytes were altered in pregnancies affected with Down's syndrome (triple test).

Induction of labour versus expectant management for large-for-date fetuses: a randomised controlled trial.

Background: Macrosomic fetuses are at increased risk of shoulder dystocia. We aimed to compare induction of labour with expectant management for large-for-date fetuses for prevention of shoulder dystocia and other neonatal and maternal morbidity associated with macrosomia.

Methods: We did this pragmatic, randomised controlled trial between Oct 1, 2002, and Jan 1, 2009, in 19 tertiary-care centres in France, Switzerland, and Belgium.
