OBJECTIVE To investigate the predictive value of serum C3 and C4 complement component levels in relation to pregnancy outcome in patients with antiphospholipid syndrome (APS). MATERIALS AND METHODS A prospective study of 47 pregnancies associated with APS was performed. Pregnancy outcome was analyzed in terms of: fetal loss, preterm delivery (≤34 gestational weeks), fetal intrauterine growth ...

The association between birth weight and mortality is among the strongest seen in epidemiology. While preterm delivery causes both small babies and high mortality, it does not explain this association. Fetal growth restriction has also been proposed, although its features are unclear because it lacks a definition independent of weight. If, as some postulate, birth weight is not itself on the ca...

In the idiopathic intrauterine growth restriction where there are no clear maternal or fetal causes, the placenta may hold the key to its etiology. So, this study was undertaken to look for any placental and umbilical cord abnormality and to establish the relationship of fetal birth weight with placental measurements. In this study, 100 freshly delivered placentae were collected. The placenta a...

Fifteen Hereford and 47 crossbred heifers were allotted by breed and body weight to be artificially inseminated to one of two Angus sires selected for progeny birth weights (L = low; H = high). Forty-two of the heifers were randomly assigned to be slaughtered at 200, 215, 230, 245 or 260 d of gestation for measurement of fetal and placental characteristics. Twenty heifers were allowed to go to ...

Methods: Forty-one pregnant woman with moderate and severe mitral stenosis were enrolled in the study. Predictor variables were the apgar score, new born weight and delivery week. Progression of NYHA functional class, thromboembolism, death, new onset atrial fibrillation was accepted as maternal event. Abortion, fetal or neonatal death, prematurity or low birth weight were accepted as fetal eve...
