AIM: The aim of this study was to determine the effects of obesity on amniotic fluid (AF) inflammatory markers in second-trimester AF, testing the hypothesis that there is a relationship between maternal body mass index (BMI) and fetal inflammatory exposure. METHODS: AF was obtained from 84 singleton pregnant women undergoing elective amniocentesis for karyotype analysis at 16-24 weeks of gestation between April 2014 and May 2016. The cell-free AF was used to analyze interleukin (IL)-1β and IL-6, and matrix metalloproteinase (MMP)-1, MMP-6, and MMP-13...

Chronic hepatitis B virus (HBV) infection leads to a risk of developing cirrhosis and hepatocellular carcinoma. In France, where the prevalence of HBV is low, mother-to-child transmission is the cause of chronic infection in more than one-third of cases. After exposure, the risk of chronic infection is the highest for newborns (90 %). The World Health Organization implemented a global immunization program in 1991, applied in France in 1994. A significant number of children are infected each year, however, and failure of postexposure prophylaxis is reported in 4-10 % of newborns...

To evaluate, side by side, the efficiency of dried blood spots (DBSs) against serum screening for Down's syndrome, and then, to construct a two-tier strategy by topping up the fetal cell-free DNA (cfDNA) secondary screening over the high-risk women marked by the primary blood testing to build a practical screening tactic to identify fetal Down's syndrome. One thousand eight hundred and thirty-seven low-risk Chinese women, with singleton pregnancy, were enrolled for the study. Alpha-fetoprotein and free beta human chorionic gonadotropin were measured for the serum as well as for the parallel DBS samples...

BACKGROUND: Analysis of cell-free foetal DNA (cff-DNA) in maternal plasma is very promising for early diagnosis of monogenic diseases; in particular, cystic fibrosis (CF). However, NIPD of single-gene disorders has been limited by the availability of suitable technical platforms and the need to set up patient or disease-specific custom-made approaches. METHODS: To make research applications more readily accessible to the clinic, we offer a simple assay combining two independent methods to determine the presence or absence of paternally inherited foetal allele p...

OBJECTIVE: Pallister-Killian syndrome (PKS) is a rare, sporadic genetic disorder caused by mosaic tetrasomy of the short arm of chromosome 12 (12p). Clinically, PKS is characterized by several systemic abnormalities, such as intellectual impairment, hearing loss, epilepsy, hypotonia, craniofacial dysmorphism, pigmentary skin anomalies, epilepsy, and a variety of congenital malformations. Prenatally, PKS can be suspected in the presence of ultrasound anomalies: diaphragmatic hernia, rhizomelic micromelia, hydrops fetalis, fetal overweight, ventriculomegaly in the central nervous system, congenital heart defects, or absent visualization of the stomach...

Endothelial dysfunction is a principle feature of vascular-related disease. Endothelial cells have been acquired for the purposes of the restoration of damaged tissue in therapeutic angiogenesis. However, their use is limited by expansion capacity and the small amount of cells that are obtained. Human amniotic fluid mesenchymal stem cells (hAF-MSCs) are considered an important source for vascular tissue engineering. In this study, hAF-MSCs were characterized and then induced in order to differentiate into the endothelial-like cells...

REVIEW
Dong-Zhi Li, Yan-Dong Yang
Thalassemia is the most common monogenic inherited disease worldwide, affecting individuals originating from many countries to various extents. As the disease requires long-term care, prevention of the homozygous state presents a substantial global disease burden. The comprehensively preventive programs involve carrier detections, molecular diagnostics, genetic counseling, and prenatal diagnosis. Invasive prenatal diagnosis refers to obtaining fetal material by chorionic villus sampling (CVS) at the first trimester, and by amniocentesis or cordocentesis at the second trimester...

Inflammation plays an important role in pregnancy, and cytokine and matrix metalloproteases (MMPs) imbalance has been associated with premature rupture of membranes and increased risk of preterm delivery. Previous studies have demonstrated that lactoferrin (LF), an iron-binding protein with anti-inflammatory properties, is able to decrease amniotic fluid (AF) levels of IL-6. Therefore, we aimed to evaluate the effect of vaginal LF administration on amniotic fluid PGE2 level and MMP-TIMP system in women undergoing genetic amniocentesis...
