The New York Times (3/4, Baumgaertner ) reports, “Toddlers who are exposed to more screen time have fewer conversations with their parents or caregivers by an array of measures. They say less, hear less and have fewer back-and-forth exchanges with adults compared with children who spend less time in front of screens.” These results, “published on Monday in the journal JAMA Pediatrics, make up one of the first sets of longitudinal evidence to confirm an intuitive reality: Screens are not just linked to higher rates of obesity, depression and hyperactivity among children; they also curb face-to-face interactions at home – with long-term implications that could be worrisome.”

MedPage Today (3/4, DePeau-Wilson ) reports, “The proliferation of ketamine clinics in the U.S. has veered far off course from the recommendations of the nation’s premier psychiatric association when it comes to using the anesthetic to treat mood disorders, experts say.” MedPage Today adds, “In 2017, the American Psychiatric Association (APA) issued a consensus statement on the use of ketamine in treating mood disorders, published in JAMA Psychiatry.” However, “the ketamine clinics cropping up across the U.S. don’t appear to follow that guidance, Smita Das, MD, PhD, MPH, of Stanford University and a spokesperson for the APA, told MedPage Today.” Dr. Das said, “[Intravenous] ketamine is being offered in smaller clinics off-label and there isn’t a practice guideline from the American Psychiatric Association that’s recommending ketamine for use in the way that it’s being used.” Dr. Das also “said the surge of ketamine clinics is something of a ‘wild west’ where vulnerable patients are being offered treatment without being informed of the downsides.”
