Millions embrace COVID-19 misinformation, which is linked to vaccine hesitancy

Millions continue to believe misinformation about vaccination and COVID-19, and these beliefs are associated with hesitancy to get themselves and their children vaccinated—or, if they are vaccinated, to get a booster for added protection.

Hospitalizations for eating disorder increased during pandemic

Researchers can’t yet pinpoint definitive reasons, though they surmise it was a combination of factors, including stress, an outsized focus on weight gain and personal appearance, and maybe even symptoms of COVID-19 itself.

How observation units and texting shortened hospital stays during COVID-19

An analysis of hospital care for COVID-19 patients shows that while short hospitalizations were often unavoidable, it is be possible to expedite the discharge for patients who could continue to recover at home, with some additional clinical support from the health system.
