There were 75 smokers, 1008 non-smokers and 194 women in whom smoking status was undetermined. All groups were matched for age, gestation an

A nested case-control study using stored serum samples collected as part of a prospective study of the outcome of pregnancy was performed to investigate concentrations of (dimeric) inhibin-A in maternal serum between 15 and 22 weeks of pregnancy in 200 twin pregnancies and 600 singleton control preg
Maternal serum inhibin-A concentration is a useful marker in prenatal screening for Down syndrome in the second trimester. We measured inhibin-A concentrations in 4304 pregnancies without Down syndrome between 14 and 22 weeks of pregnancy to determine the median values according to gestational age.
In an analysis of 3111 singleton pregnancies routinely screened in the first trimester with nuchal translucency, free beta hCG and pregnancy associated plasma protein A (PAPP-A) smoking has been found to occur in 20.8 per cent of pregnant women. When the individual marker levels were assessed in smo
