Hormones are both growth stimulatory and growth inhibitory in utero. They regulate tissue growth and development by controlling the rates of cell proliferation, apoptosis and differentiation in many fetal tissues. They also signal the level of resources available for intrauterine growth to the fetal tissues and relay back to the placenta the degree of mismatch between the actual fetal nutrient ...
Fetal growth is a complex and dynamic process regulated by a large number of interactive factors of fetal, maternal, and placental origin. As a result, any abnormality of fetal growth has a complex multifactorial pathogenesis. It has been estimated that about 50% of intrauterine fetal growth is determined by fetal genes. Maternal disease, her nutritional intake and behaviours, such as smoking, ...
BACKGROUND Worldwide, stillbirth is one of the leading causes of death. Altered fetal growth and placental abnormalities are the strongest and most prevalent known risk factors for stillbirth. The aim of this study was to identify patterns of association between placental abnormalities, fetal growth, and stillbirth. METHODS AND FINDINGS Population-based case-control study of all stillbirths a...
BACKGROUND Pregnancy associated malaria is associated with decreased birth weight, but in-utero evaluation of fetal growth alterations is rarely performed. The objective of this study was to investigate malaria induced changes in fetal growth during the 3(rd) trimester using trans-abdominal ultrasound. METHODS An observational study of 876 pregnant women (398 primi- and secundigravidae and 47...
BACKGROUND The most well known reproductive consequence of residence at high altitude (HA >2700 m) is reduction in fetal growth. Reduced fetoplacental oxygenation is an underlying cause of pregnancy pathologies, including intrauterine growth restriction and preeclampsia, which are more common at HA. Therefore, altitude is a natural experimental model to study the etiology of pregnancy pathophys...
