Blood Chemistry of Normal Human Fetuses at Midtrimester of Pregnancy

Midtrimester amniotic fluid adiponectin in normal pregnancy.

0.0001 by Wilcoxon signed-rank test) and based on the 99th percentile values for each assay, 9 discordances were found between assays for values within the reference interval vs increased values. The ADVIA TnI-Ultra method showed no interference from dilutions with plasma samples that contained high concentration of triglycerides (6.6 g/L, final dilution 1:128; y 0.044 0.14x, n 8, R 0.99) or he...

Estimation of uterine blood flow in normal human pregnancy at term.

Behavioural states in normal mature human fetuses.

Behaviour was studied by real time ultrasound in a group of 80 low risk fetuses between 36 and 42 weeks' gestation. There was close linkage of fetal eye movements, somatic movements and heart rate pattern reflecting three different states. Quiescence (state 1F) was characterised by no eye movements, no somatic movements except for the occasional startle, and a fetal heart rate pattern with litt...

Pregnancy loss rates after midtrimester amniocentesis.

OBJECTIVE The purpose of this study was to quantify the contemporary procedure-related loss rate after midtrimester amniocentesis using a database generated from patients who were recruited to the First And Second Trimester Evaluation of Risk for Aneuploidy trial. METHODS A total of 35,003 unselected patients from the general population with viable singleton pregnancies were enrolled in the F...

Ovarian torsion in a midtrimester pregnancy

Objective Maternal ovarian torsion in pregnancy is a rare complication. Its diagnosis is often missed due to the nonspecific clinical features and uncommon objective findings. Ovarian torsion is seen most commonly at first trimester, but can happen second or third trimester. In late pregnancy, especially in the second and third trimesters, the diagnostic accuracy of ultrasound is limited becaus...
