Anorexia linked to metabolism, shows study A new study links anorexia as an illness to one’s metabolism. The study, from the journal Nature Genetics, examined DNA of 17,000 people with anorexia nervosa and 55,000 healthy controlled subjects. Researchers found eight genetic markers that correlate the illness to the risk for psychiatric disorders like obsessive compulsive disorder, depression and anxiety. Metabolic and anthropometic traits, such as a low body mass index, also saw links. Treatments are currently centring on behaviour therapy, but that will soon change. •
Increased social media use ties to depression in teens S crolling through social media and watching TV is leading to depression symptoms in youth, says a recent study. Journal JAMA Pediatrics reported screen time and depression are linked, and say every hour youth spend on social media or watching TV can cause the severity of symptoms to rise. The study examined 3,826 students from seventh to 11th grade in 31 schools across Montreal. The six-year study asked students to complete surveys from 2012 to 2018. High social media use over four years was associated with increaseddepression. High levels of computer use over the same span did not have the same correlation. There were no significant associations with video games either.
Adults who vape more likely to quit smoking cigarettes: Study finds A new study shows adult smokers who vape are more likely to quit smoking cigarettes. However, e-cigarettes increase the risk of a relapse in former smokers. E-cigarette use may affect current and former smokers differently, in that those addicted to cigarettes are likely to quit the habit, but those who quit can be drawn back in. Medical journal JAMA Internal Medicine tracked 5,000 daily smokers for two years in France. Smokers who vaped were more than 1.5 times likely to quit completely.
First North American baby delivered from deceased-donor uterine transplant I t was a historic day July 8th when the first North American baby was delivered via a deceased-donor uterine transplant. Cleveland Clinic’s procedure was just the second done worldwide. The uterus was transplanted from a donor who had already passed on. The baby was delivered “en caul” meaning the amniotic sac remained in tact until after the delivery. The research team behind the work came from 20 different specialties, with transplant surgeon Andreas Tzakis heading the procedure.
