Artificial intelligence (AI) may be able to identify alcoholics at risk of relapsing after treatment, researchers say. Patients often return to heavy drinking during and after treatment, and may require multiple tries before they can achieve long-term abstinence from unhealthy alcohol use. AI may allow care providers and patients to predict drinking relapses and adjust…  read on >  read on >

People with substance abuse disorders, depression and other mental health conditions may be at higher risk for COVID-19 — even when they are fully vaccinated, new research suggests. “Individuals with psychiatric disorders, and especially older adults with psychiatric disorders, may be particularly vulnerable to breakthrough infections,” said study author Kristen Nishimi, a postdoctoral fellow at…  read on >  read on >

Moderna’s COVID-19 vaccine may have some slight advantages over the Pfizer shot, new research suggests. For the study, researchers tracked antibody levels in 234 people for 10 months after they received either the two-dose Pfizer (114 people) or Moderna (114 people) mRNA vaccines, or the single-dose Johnson & Johnson (6 people) shot, which uses a…  read on >  read on >

U.S. health care workers were most likely to be infected with COVID-19 at work during the pandemic’s first year, according to a new study that challenges previous research suggesting their risk was highest off the job. Researchers said their findings could help guide efforts to better protect health care workers during future infectious disease outbreaks.…  read on >  read on >
