Elevations of group II phospholipase A(sub 2) concentrations in serum and amniotic fluid in association with preterm labor

Article Abstract:

Increased levels of group II phospholipase A(sub 2) in blood and amniotic fluid may be a marker of premature birth. It may also be a marker of intrauterine infection, which is a known risk factor for premature birth.

The effects of repeated corticosteroid administration on the neurogenesis in the neonatal rat

Article Abstract:

The study is carried out to clarify the effects on the brain, including neurogenesis pretreated with repeated doses of dexamethasone in the neonatal rat. It concludes that the decreases in neurogenesis caused by repeated antenatal corticosteroid therapy can result in the adverse effects on the size of the head at birth.

Effect of sexual intercourse on fetal fibronectin concentration in cervicovaginal secretions

Article Abstract:

Pregnant women should not be tested for fetal fibronectin if they have had sexual intercourse in the previous three days. Fetal fibronectin in cervical fluid is often a risk factor for premature birth. However, sperm and semen have a chemical similar to fetal fibronectin that could cause a false-positive test in women who recently had sexual intercourse. Researchers measured fetal fibronectin in cervical fluid taken from 14 non-pregnant women. Twenty-two percent tested positive for fetal fibronectin 12 to 24 hours after intercourse, 12% tested positive 24 to 48 hours after intercourse, and 6% tested positive 48 to 72 hours after intercourse.
