The primary objective in modern obstetrics and prenatal diagnosis is to predict risks of congenital abnormalities. The aim of the research was to assess the correlation between selected oxidative stress biomarkers with the risk of foetal chromosomal aberration evaluated at the first trimester screening. A series of studies show that balanced free radical activity and oxidative homeostasis are essential for proper bodily growth and function. Reactive oxygen species (ROS) may be one of the factors associated with disruption of cell cycle and tissue development, thus leading to developmental abnormalities...

This retrospective study assessed fasting plasma glucose (FPG) and body mass index (BMI) during the first trimester of pregnancy as potential screening indicators of later gestational diabetes mellitus (GDM). The study population included 820 pregnant women who delivered in our hospital between 17 September 2013 and 3 March 2014. Demographics and baseline characteristics were collected at the first antenatal visit; FPG levels were measured at 8 or 9 weeks. All participants underwent a 75-g oral glucose tolerance test at 24-28 weeks gestation...

So far data on the effect of assisted reproductive technologies (ART) on the components of first trimester combined screening for Down syndrome are still controversial. A systematic search of the literature was performed in order to identify the effect of ART, particularly IVF and ICSI with fresh embryo transfer, on the nuchal translucency (NT), free β-hCG and PAPP-A measurements. Moreover, a meta-analysis and a descriptive graphical representation of the ratios between ART and spontaneous pregnancies (controls) values of median of the multiple of median (m0MOM) was performed...

OBJECTIVES: Sonographic evaluation of the palate is a difficult task, and most palatine clefts are diagnosed in the neonatal period because of the limitations of 2-dimensional (2D) sonography. The objective is to describe a sonographic technique based on 2D markers for screening of palatine clefts during the nuchal translucency scan and to assess the ability of 3-dimensional (3D) sonography in imaging the normal and abnormal palate. METHODS: A total of 2014 women who enrolled for first-trimester screening were included in this prospective study...

OBJECTIVE: To calculate the proportion of array comparative genomic hybridization (aCGH) pathogenic results, that would not be detectable by non-invasive prenatal screening (NIPS). METHODS: This is a comparative study using data from 2,779 fetuses, which underwent invasive prenatal diagnosis and the samples were analyzed using aCGH. The simulated NIPS assay would test for trisomies 21, 18, 13, monosomy X, 47,XXX, 47,XYY and 47,XXY. Indications for invasive testing were grouped into categories and the absolute, relative rates of pathogenic/likely pathogenic results of aCGH analysis that would not be detectable by NIPS, were calculated...

The cellular and molecular mechanisms responsible for pregnancy-related disorders remain unclear. We investigated the feasibility of using placenta-derived mesenchymal stem cells (MSCs) as a tool to study such pregnancy-related disorders. We isolated and expanded adequate numbers of cells with characteristic features of MSCs from the chorionic plate (CP-MSCs), chorionic villi (CV-MSCs), and decidua basalis (DB-MSCs) of human term placental tissues. All placenta-derived MSCs expressed pregnancy-associated C14MC microRNA (miRNA) (miR-323-3p)...

BACKGROUND: Although there have been marked improvements in our understanding of vitamin D functions in different diseases, gaps on its role during pregnancy remain. Due to the lack of consensus on the most accurate marker of vitamin D deficiency during pregnancy and the optimal level of 25-hydroxyvitamin D, 25(OH)D, for its definition, vitamin D deficiency assessment during pregnancy is a complicated process. Besides, the optimal protocol for treatment of hypovitaminosis D and its effect on maternal and neonatal outcomes are still unclear...

INTRODUCTION: The non-invasive prenatal test (NIPT) was introduced in the North Denmark Region in March 2013. NIPT is offered as an alternative to invasive tests if the combined first trimester risk of trisomy 21 (T21) is ≥ 1:300. The purpose of this study was to investigate the effect of NIPT implementation among high-risk pregnancies in a region with existing first-trimester combined screening for T21. The primary objective was to examine the effect on the invasive testing rate. METHODS: This was a retrospective observational study including high-risk singleton pregnancies in the North Denmark Region...
