16 Emerging research has highlighted the importance of leptin in fetal growth and development, 17 independent of its essential role in the maintenance of hunger and satiety through the modulat 18 ion of neuropeptide Y and proopiomelanocortin neurons. Alterations in maternal-placental-fet 19 al leptin exchange may modify the development of the fetus and contribute to the increased ri 20 sk of de...

OBJECTIVE Investigation of the possible role of leptin in early pregnancy failure. METHODS Leptin concentration was measured in maternal serum, coelomic fluid and amniotic fluid from 15 singleton pregnancies with live fetuses and 7 missed miscarriages at 7-10 weeks of gestation. RESULTS In the pregnancies with live fetuses, the median leptin concentration was significantly higher in coelomi...

Increased maternal blood concentrations of leptin and decreased adiponectin levels, which are common disturbances in obesity, may be involved in offspring adiposity by programming fetal adipose tissue development. The aim of this study was to assess the relationship between maternal leptin and adiponectin concentrations and newborn adiposity. This was a cross-sectional study involving 210 healt...

Leptin is a hormone that is secreted by adipose cells in proportion to adipose mass, and therefore a low leptin level signifies depletion of energy stores. It has been proposed that leptin is one of the signals controlling sexual maturation. For example, humans and rodents lacking leptin fail to undergo complete puberty, while overexpression of leptin in mice causes early puberty. The placenta ...

BACKGROUND Leptin and insulin levels are key factors regulating fetal and neonatal energy homeostasis, development and growth. Both biomarkers are used as predictors of weight gain and obesity during infancy. There are currently no prediction algorithms for cord blood (UCB) hormone levels using Artificial Neural Networks (ANN) that have been directly trained with anthropometric maternal and neo...

AIMS To investigate the importance of a maternal and paternal family history of Type 2 diabetes and their combined association with plasma leptin and adiponectin levels in overweight Latino children with a family history of Type 2 diabetes (T2DM). METHODS This cross-sectional study investigated the combined association of a maternal and paternal family history of T2DM with leptin and adiponec...

OBJECTIVE Few studies have examined whether the distinct metabolic patterns found in obese and nonobese pregnant women have different effects on the growing fetus. Our objective was to estimate the influence of longitudinal variation in maternal serum leptin levels on variation in infant birth weight in overweight/obese versus normal-weight women. DESIGN AND METHODS In a prospective cohort of...

Background: Gestational weight gain is an impressive factor in the fetal outcome. Intrauterine growth restriction (IUGR) is one of the most important problems during fetal period that may lead to many perinatal and long-term complications and growing neonatal morbidities and mortalities. The aim of the study was to ascertain the relationship between umbilical cord blood leptin concentration and...

BACKGROUND Fetal growth restriction (FGR) is a condition with heterogeneous pathophysiology which characterized by fetal weight less than the tenth percentile for gestational age. Several factors have impact on maternal, placental and fetal due to growth restriction. OBJECTIVE The aim of this study was to investigate the relationship between levels of leptin in the cord, and serum leptin of m...
