Prenatal screening generates a great amount of data that is used for predicting risk of various disorders. Prenatal risk assessment is based on multiple clinical variables and overall performance is defined by how well the risk algorithm is optimized for the population in question. This article evaluates machine learning algorithms to improve performance of first trimester screening of Down syndrome. Machine learning algorithms pose an adaptive alternative to develop better risk assessment models using the existing clinical variables...

In 2004 the Danish National Board of Health changed its screening recommendations. Since 2005 a first trimester screening for Down syndrome and a prenatal ultrasound screening for congenital anomalies in the second trimester of pregnancy has been offered to all pregnant women. The aim of this study was to describe the prevalence of cleft lip with or without cleft palate and cleft palate in a Danish area and to describe associated anomalies and the development in prenatal diagnosis over time. The study was based on data from the EUROCAT Registry for Funen County...

Objective: To evaluate the agreement of risk categorization for Down syndrome screening between ultrasound scan-based gestational age (GA) and last menstrual period-based gestational age in both first and second trimesters by maternal serum markers. Methods: Data comprising 4,055 and 4,016 cases of first and second trimester screening were used. The maternal serum markers were analyzed using the ultrasound-based GA and menstrual age. The subjects whose menstrual age and ultrasound-based GA fell in different trimesters were excluded because the risk could not be calculated due to the different serum markers used in each trimester...

OBJECTIVE: To examine the effect of first trimester screening for preeclampsia (PE) on the prediction of small for gestational age (SGA) neonates and the effect of prophylactic use of aspirin on the prevention of SGA. METHODS: The data for this study were derived from two multicentre studies. In SPREE we investigated the performance of screening for PE by a combination of maternal characteristics and biomarkers at 11-13 weeks' gestation. In ASPRE women with singleton pregnancies identified by combined screening as being at high risk for preterm-PE (>1 in 100) participated in a trial of aspirin (150 mg/day from 11 to 14 until 36 weeks' gestation), compared to placebo...

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...

In the debate surrounding the introduction of non-invasive prenatal testing (NIPT) in prenatal screening programmes, the concept of routinisation is often used to refer to concerns and potential negative consequences of the test. A literature analysis shows that routinisation has many different meanings, which can be distinguished in three major versions of the concept. Each of these versions comprises several inter-related fears and concerns regarding prenatal screening and particularly regarding NIPT in three areas: (1) informed choice, (2) freedom to choose and (3) consequences for people with a disability...

BACKGROUND: Established therapies for managing kidney dysfunction such as kidney dialysis and transplantation are limited due to the shortage of compatible donated organs and high costs. Stem cell-based therapies are currently under investigation as an alternative treatment option. As amniotic fluid is composed of fetal urine harboring mesenchymal stem cells (AF-MSCs), we hypothesized that third-trimester amniotic fluid could be a novel source of renal progenitor and differentiated cells...

Early initiation of prenatal care is associated with improved health outcomes for women and newborns. An essential element of prenatal care is determining the estimated due date, ideally using a first-trimester ultrasound. Laboratory tests should be obtained to screen for conditions that can affect pregnancy. Routine immunizations for all pregnant women include influenza vaccine; tetanus toxoid, reduced diphtheria, acellular pertussis (Tdap) vaccine. All women should be screened for gestational diabetes mellitus in midpregnancy...

AIMS: Gestational diabetes mellitus (GDM) affects between 5 to 10 % of all pregnancies in Canada and can lead to adverse health outcomes in both the mother and fetus. Amino acids (AA) and acylcarnitines (AC) have been identified as early biomarkers of type 2 diabetes but their usefulness in screening for GDM has yet to be demonstrated. METHODS: We conducted a nested case-control study involving 50 controls and 50 GDM cases diagnosed between the 24th and 28th week of gestation...
