Obesity is an important public health issue worldwide, where it is commonly associated with the development of metabolic disorders, especially insulin resistance (IR). Maternal obesity is associated with an increased risk of pregnancy complications, especially gestational diabetes mellitus (GDM). Metabolism is a vital process for energy production and the maintenance of essential cellular funct...
OBJECTIVE To investigate the relationship between placenta-mediated pregnancy complications and bronchopulmonary dysplasia (BPD) in very preterm infants. METHODS National prospective population-based cohort study including 2697 singletons born before 32 weeks' gestation. The main outcome measure was moderate to severe BPD. Three groups of placenta-mediated pregnancy complications were compare...
Passage of environmental chemicals across the placenta has important toxicological consequences, as well as for choosing samples for analysis and for interpreting the results. To obtain systematic data, we collected in 2000 maternal and cord blood, cord tissue, placenta, and milk in connection with births in the Faroe Islands, where exposures to marine contaminants is increased. In 15 sample se...
BACKGROUND The incidence of placenta previa has been increasing. It is of a great importance to determine the clinical risk factors for peripartum blood transfusion in women with placenta previa in an effort to anticipate cases of severe hemorrhage. METHODS A total of 129 consecutive cases of placenta previa (64 cases of complete placenta previa and 65 cases of marginal placenta previa), incl...
placenta plays a vital role in normal fetal development and failure of placenta to gain weight and insufficiency of its function can result in fetal disorders. we performed this study to determine placental weight and factors associated with low weight placentas. in a longitudinal cross-sectional study, women with single pregnancy, and gestational age between 37-42 weeks were studied. the subje...
OBJECTIVES To determine blood-lead (Pb) levels in pregnant women and neonates in a metallurgical city of Peru. MATERIALS AND METHODS A cross-sectional study was carried out, the population of which consisted of pregnant women who had lived for at least two years in the city of La Oroya, at the time when the lead, copper and zinc foundries operated normally. A blood sample was obtained from th...
Maternal high fat and salt consumption are associated with developmental programming of disease in adult offspring. Inadequacies in placental nutrient transport may explain these 'programmed effects'. Diet-induced inflammation may have detrimental effects on placental function leading to alteration of key nutrient transporters. We examined the effects of maternal high fat and/or salt diets on m...
Maternal lipoproteins provide nutrients to the fetus via the placenta, yolk sac, and uterine membrane plus decidua. To determine the transport processes that are responsible for the removal of lipoproteins from the maternal circulation, we measured the clearance rates of maternal LDL and HDL in vivo, as well as the tissue distribution of expression of the LDL receptor, glycoprotein 330 (gp330) ...
Matrotrophic fish in the genus Poeciliopsis (Poeciliidae) have a placenta-like structure used in postfertilization maternal provisioning of the developing embryo. To understand better the structure and function of the Poeciliopsis placenta, we derived cDNA libraries from the maternal follicular placenta of 2 matrotrophic Poeciliopsis sister species, P. turneri and P. presidionis. These species ...
Antepartum haemorrhage is an important obstetric emergency and carries increased risk of maternal and perinatal morbidity and mortality. It commonly arises from the placenta as placenta praevia or placental abruption and rarely it may be from a vasa 1 praevia or local lesions in the cervix or vagina . It is crucial to distinguish between these causes from the outset as their definitive manageme...
