Very low risk to newborns from moms with COVID-19, finds study — ScienceDaily

Mothers with SARS-CoV-2 infection rarely transmit the virus to their newborns when basic infection-control practices are followed, according to a new study by researchers at Columbia University Irving Medical Center and NewYork-Presbyterian Morgan Stanley Children’s Hospital. The findings — the most detailed data available on the risk of SARS-CoV-2 transmission between moms and their newborns — suggest that more extensive measures like separating COVID-19-positive mothers from their newborns and avoiding direct breastfeeding may not be warranted.

The study was published online today in JAMA Pediatrics.

“Our findings should reassure expectant mothers with COVID-19 that basic infection-control measures during and after childbirth — such as wearing a mask and engaging in breast and hand hygiene when holding or breastfeeding a baby — protected newborns from infection in this series,” says Cynthia Gyamfi-Bannerman, MD, MSc, the Ellen Jacobson Levine and Eugene Jacobson Professor of Women’s Health in Obstetrics and Gynecology at

Discovery enables adult skin to regenerate like a newborn’s — ScienceDaily

A newly identified genetic factor allows adult skin to repair itself like the skin of a newborn babe. The discovery by Washington State University researchers has implications for better skin wound treatment as well as preventing some of the aging process in skin.

In a study, published in the journal eLife on Sept. 29, the researchers identified a factor that acts like a molecular switch in the skin of baby mice that controls the formation of hair follicles as they develop during the first week of life. The switch is mostly turned off after skin forms and remains off in adult tissue. When it was activated in specialized cells in adult mice, their skin was able to heal wounds without scarring. The reformed skin even included fur and could make goose bumps, an ability that is lost in adult human scars.

“We were able to take the innate ability of
