New study reveals exosome-mediated communication between mother and baby   During pregnancy, the mother and the baby communicate in a variety of ways. For instance, signals from the fetus are crucially involved in the initiation of labor and delivery. One important means of such signaling is the passage of packages called exosomes, which are very small particles released from every cell. These are only about 30 to 150 nm in diameter, and travel in both directions between mother and fetus. Exosomes contain chemicals which act as signals between maternal and fetal tissues.

Exercise during pregnancy shown to restore metabolic health   Researchers at the University of Cambridge have discovered how exercising before and during pregnancy, reduces the risk of long-term health issues for both mother and baby. In a study of obese pregnant mice, exercise restored key tissues and improved management of blood glucose, thereby reducing the risk of metabolic problems such as type 2 diabetes.         Early planned delivery reduces impact of preterm pre-eclampsia   Doctors have long debated over the optimal time to deliver mothers with pre-eclampsia in late pregnancy (after 34 but before 37 completed weeks). This is because too early delivery compromises the baby’s health, while delayed action may endanger the mother’s health.

Claims that cesarean sections increase the risk of autism are “highly unlikely”, say experts   Recent research into over 20 million births concluded that babies born by Cesarean section are more likely to develop autism. Analysis of 61 studies has also found that babies born by Cesarean are a sixth more likely to develop attention deficit hyperactivity disorder (ADHD).       Blood pressure in children affected by early environmental exposures   Hypertension or high blood pressure is a major killer worldwide, accounting for much death and disease burden due to cardiovascular disease. Multiple factors influence the risk for this condition, some acting in adulthood but some operating from birth or even earlier.       Exposure to pesticides in the womb linked to changes in brain activity in adolescents   Pesticide exposure has been linked to many conditions, especially after long-term exposure. These chemicals can cause short-term adverse effects and in some cases, chronic adverse health effects that can emerge months or even years after exposure.
