Effect of chorionic villus sampling and early pregnancy counselling on uptake of prenatal diagnosis.
An early pregnancy counselling clinic was introduced to improve the uptake of prenatal diagnosis and to offer chorionic villus sampling to women aged 38 and over by their expected date of delivery. Ninety eight (62%) unselected older mothers were seen before 11 weeks' gestation, and 23 (32%) of those with viable pregnancies elected to undergo chorionic villus sampling compared with 38 (52%) ele...
BACKGROUND Worldwide, stillbirth is one of the leading causes of death. Altered fetal growth and placental abnormalities are the strongest and most prevalent known risk factors for stillbirth. The aim of this study was to identify patterns of association between placental abnormalities, fetal growth, and stillbirth. METHODS AND FINDINGS Population-based case-control study of all stillbirths a...
Calcitonin gene-related peptide (CGRP), one of the most potent endogenous vasodilators known, has been implicated in vascular adaptations and placental functions during pregnancy. The present study was designed to examine the existence of CGRP-A receptor components, the calcitonin receptor-like receptor (CRLR) and receptor activity-modifying protein 1 (RAMP1), in the human placenta and the vaso...
Trophoblast biologists are often uncertain as to what cell types they are investigating because the mononuclear cell populations prepared from trypsinization of human first-trimester chorionic villi are morphologically very similar. In the present study, immunocytochemical and phagocytic markers have been used to distinguish cytotrophoblast populations from cell types derived from the mesenchym...
OBJECTIVE To investigate whether amniocentesis and chorionic villus sampling increase the risk of postural deformities, limb reduction defects, respiratory problems in the newborn, fetal and infant mortality, prematurity, low birthweight and fetal distress, and to investigate the impact of gestational length at the time of the procedure. DESIGN A population-based cohort study. SETTING Swede...
The effects of exposure to a sinusoidal 50-Hz magnetic field (MF) and an incoherent (noise) MF on hormone secretion in human first trimester villous trophoblasts were investigated. Trophoblasts were isolated from more than 30 first trimester human chorionic villi of 8-10 weeks gestation. They were cultured and exposed to MFs for different durations. The concentrations of human chorionic gonadot...
