Weight-loss surgeries among adolescents increased substantially in recent years, part of an overall rise in obesity treatments in the US. The number of adolescents ages 10 to 19 who underwent metabolic or bariatric surgery rose about 20% in 2021 from the year before, according to a research letter published Tuesday in the Journal of the American Medical Association, Pediatrics. Rates of these surgeries, which are uncommon, also rose among minors between 2019 and 2020, even as rates for adults dipped. (Peng and Court, 5/30)

A new study has found a rapid decline in global cognition, memory and executive function in those who suffer from a heart attack compared to those who do not. In a study published in the JAMA Neurology journal, researchers found that people who suffered from at least one or more incidents of myocardial infarction (MI), also known as a heart attack, had a "significantly faster" rate of decline in global cognition, memory and executive function over the years compared to those who did not. The research also found that having a heart attack was not associated with an immediate decrease in these functions after the event, but rather impacted long-term brain health. (Sforza, 5/30)

�������ýҕ�l Health News: Mood-Altering Mushroom Sales Bloom Despite Safety Concerns 

When a hemp dispensary in this Florida city started to stock edibles with certain mushroom extracts last year, state regulators quickly ordered it to stop selling the items. The shop had been advertising fruit-flavored gummies and other products containing tiny doses of mood-altering chemicals from the mushroom Amanita muscaria.
