OBJECTIVE: To better adjust the risk for preeclampsia, multifactorial models in first trimester of pregnancy have found the way in clinical practice. This study compares the available test algorithms. STUDY DESIGN: In a cross-sectional study between November 2013 and April 2016 we compared the tests results of three first trimester testing algorithms for preeclampsia in 413 women. Risk for preterm preeclampsia was calculated with three different algorithms: Preeclampsia Predictor™ Software by PerkinElmer (PERK), ViewPoint® Software by GE Healthcare (VP) and the online calculator of the Fetal Medicine Foundation (FMF)...

Thalassaemia is one of the commonest inherited disorders in Bangladesh. Since population is rapidly increasing in Bangladesh, therefore birth of large number of new cases is expected every year. Chorionic villus sampling (CVS) is an invasive diagnostic procedure done in early pregnancy to obtain fetal cells for the prenatal diagnosis of chromosomal and genetic disorders like thalassemia. To investigate the feasibility, safety, and outcome of transabdominal Chorionic Villus Sampling (CVS) for prenatal diagnosis of Beta Thalassemia, this retrospective analytical study was carried out on women who had undergone transabdominal CVS for prenatal diagnosis of Beta thalassemia...

Autism spectrum disorder (ASD) has captured the attention of scientists, clinicians and the lay public because of its uncertain origins and striking and unexplained clinical heterogeneity. Here we review genetic, genomic, cellular, postmortem, animal model, and cell model evidence that shows ASD begins in the womb. This evidence leads to a new theory that ASD is a multistage, progressive disorder of brain development, spanning nearly all of prenatal life. ASD can begin as early as the 1st and 2nd trimester with disruption of cell proliferation and differentiation...

GOALS: Preeclampsia (PE) is a leading cause of maternal and neonatal morbidity and mortality. Early treatment by aspirin has been shown to significantly reduce PE risk before 37weeks supporting the implementation of first-trimester screening. SUBJECTS AND METHODS: A targeted screening was recently implemented at Toulouse University Hospital for women in their first pregnancy or those with personal or familial history of PE. It uses Fetal Medicine Foundation (FMF) algorithm that combines maternal characteristics, clinical, biophysical and biochemical (PAPP-A, Pregnancy Associated Plasma Protein-A, and PlGF, Placental Growth Factor) data...

OBJECTIVE: Pre-eclampsia (PE) remains a leading cause of maternal and fetal morbidity and mortality. A first trimester screening algorithm predicting the risk of early onset PE has been developed and validated. Early prediction coupled with initiation of aspirin at 11 to 13 weeks in women identified as high risk is effective at reducing the prevalence of early onset PE. The aim of this study is to evaluate the cost-effectiveness of this first trimester screening program coupled with early use of low-dose aspirin in women at high risk of developing early onset PE versus current practice...

OBJECTIVE: To develop fetal and neonatal population weight charts. The rationale was that, while reference ranges of estimated fetal weight (EFW) are representative of the whole population, the traditional approach of deriving birth-weight (BW) charts is misleading, because a large proportion of babies born preterm arise from pathological pregnancy. We propose that the reference population for BW charts, as in the case of EFW charts, should comprise all babies at a given gestational age, including those still in utero...

Maternal smoking during pregnancy (MSDP) continues to be a leading modifiable risk factor for perinatal complications and a range of neurodevelopmental and cardio-metabolic outcomes across the lifespan. Despite 40 years of intervention research less than one in five pregnant smokers who receive an intervention quit by delivery. Within this context, recognition of pregnancy is commonly associated with abrupt suspension or reduction of smoking in the absence of intervention, yet has not been investigated as a volitional target...
