Prenatal Research: Prenatal exercise lowers risks of C-sections ♦ Sunshine alone not enough for vitamin D ♦ Maternal obesity compromises baby's' immune system

Prenatal exercise lowers risks of C-sections, higher birth weights Pregnant women who exercise can significantly lower the risk of undergoing cesarean sections and giving birth to large babies. Prenatal exercise has been suggested to be a means to prevent childhood obesity through a "normalization" in birth weight
Sunshine alone not enough for vitamin D during pregnancy Despite high levels of sunshine, low levels of vitamin D during pregnancy are common in Mediterranean women. This finding should help lower the prevalence of early childhood diseases associated with Vitamin D deficiency such as preeclampsia, gestational diabetes, disorders in bone formation, higher risk of emergency caesarean delivery and premature birth.
Maternal obesity compromises baby's' immune system at time of birth Maternal obesity is linked to several adverse health outcomes for the infant that can persist into adulthood. But when does the immune system of babies born to obese mothers get compromised? Very early in the baby's life, according to a study. The research team analyzed umbilical cord blood samples of infants born to lean, overweight and obese mothers, and found that pre-pregnancy maternal weight has a significant impact on the neonate's immune system.
Changes in placentas protective ability during pregnancy linked to transporter proteins An important function of the human placenta is to protect the fetus from detrimental substances in maternal blood, such as glucocorticoids or toxins. Placental membrane-bound transporter proteins, known as multidrug resistance proteins, protect the fetus by returning unwanted materials to the maternal circulation. A study now reports that bacterial and viral infections differentially influence these transporter proteins in early and late pregnancy, suggesting potential mechanisms underlying infection-related pregnancy complications such as preterm birth and fetal brain damage.
