A new study has found that mothers who delivered vaginally compared to caesarean section delivery (CSD) were significantly more responsive to the cry of their own baby, identified through MRI brain scans two to four weeks after delivery.

The results of the study, to be published today in The Journal of Child Psychology and Psychiatry, suggest that vaginal delivery (VD) mothers are more sensitive to own baby-cry in the regions of the brain that are believed to regulate emotions, motivation and habitual behaviours.

CSD is a surgical procedure, in which delivery occurs via incisions in the abdominal and uterine wall. It is considered necessary under some conditions to protect the health or survival of infant or mother, but it is controversially linked with postpartum depression. In the US the occurrence of CSD has increased steeply from 4.5% of all deliveries in 1965 to a recent high in 2006 of 29.1%.

The critical capacity of adults to develop the thoughts and behaviours needed for parents to care successfully for their newborn infants is supported by specific brain circuits and a range of hormones. The experience of childbirth by VD compared with CSD uniquely involves the pulsatile release of oxytocin from the posterior pituitary, uterine contractions and vagino-cervical stimulation. Oxytocin is a key mediator of maternal behaviour in animals.

"We wondered which brain areas would be less active in parents who delivered by caesarean section, given that this mode of delivery has been associated with decreased maternal behaviours in animal models, and a trend for increased postpartum depression in humans," said lead author Dr. James Swain, Child Study Centre, Yale University. "Our results support the theory that variations in delivery conditions such as with caesarean section, which alters the neurohormonal experiences of childbirth, might decrease the responsiveness of the human maternal brain in the early postpartum."

The researchers also looked into the brain areas affected by delivery conditions and found relationships between brain activity and measures of mood suggesting that some of the same brain regions may help regulate postpartum mood.

"As more women opt to wait until they are older to have children, and by association be more likely to have a caesarean section delivery, these results are important because they could provide better understanding of the basic neurophysiology and psychology of parent-infant attachment," said Swain. "This work could lead to early detection of families at risk for postpartum depression and attachment problems and form a model for testing interventions."

Gilead's $1000-a-Pill Drug Could Cure Hep C in HIV-Positive People

TheStreet (July 21, 2014) New research shows Gilead Science's drug Sovaldi helps in curing hepatitis C in those who suffer from HIV. In a medical study, the combination of Gilead's Hep C drug with anti-viral drug Ribavirin cured 76% of HIV-positive patients suffering from the most common hepatitis C strain. Hepatitis C and related complications have been a top cause of death in HIV-positive patients. Typical medication used to treat the disease, including interferon proteins, tended to react badly with HIV drugs. However, Sovaldi's %1,000-a-pill price tag could limit the number of patients able to access the treatment. TheStreet's Keris Lahiff reports from New York. Video provided by TheStreet
