Trial participants preferred taking a placebo over the drug, with higher dropout rates and adverse event-induced discontinuation. The findings also highlight issues with the validity of HSDD as a diagnosis.

A new study of nearly 4,000 school children found that children who felt they had empathic support from their parents and caregivers were less likely to commit serious crimes. The research also showed that parental empathy enhanced the development of empathy in teenagers, which in turn reduced delinquent behavior.
A new study reviews data from 57 studies and finds that people with asthma have a 14% lower risk of getting COVID-19 and are significantly less likely to be hospitalized.
