[Truncated abstract] Glucocorticoids are critical for the maturation of the fetus late in pregnancy. Indeed, clinical administration of glucocorticoids is used to accelerate fetal lung maturation in mothers at risk of pre-term delivery. Increased glucocorticoid exposure, however, can have detrimental effects on fetal and placental growth and increase the risk ...

The placenta, as the vector for all maternal-fetal oxygen and nutrient exchange, is a principal influence on birthweight. Placental weight summarizes laterally expanding growth of the chorionic disc, and villous arborization yielding the nutrient exchange surface. These different growth dimensions alter fetoplacental weight ratio and ponderal index, and thus may ...

Fetal growth compromise is mostly defined by gestational age specific threshold value of birth weight or ultrasonically estimated fetal weight. The most frequently used threshold is the 10th centile. However, this approach can not differentiate fetal constitutional smallness from fetal growth failure. The most common descriptor terms are fetal growth ...
Barr, Mason
Pregnant CFN Wistar rats demonstrated marked fluctuations of body weight within 24-h periods during late gestation. Maternal weight loss during the daytime phase of the daily cycle was accompanied by a slowdown in fetal growth. The period of rapid maternal weight gain that occurred during the night was paralleled by ...
