UC researcher finds stroke risk factors in minority groups

A new study led by UC researcher Daniel Woo found high blood pressure to be a significant risk factor for strokes in Black and Hispanic patients. The study also identified sleep apnea as a novel risk factor for intracerebral hemorrhage (ICH) strokes, which are often deadly and cause high disability.

Deadlines may be effective in building support for climate change action

A new University of Central Florida study found that using deadline-ism messaging in climate change communications increases perceptions of the threat and support for government action. Participants who read articles with deadlines supported more political climate change action than those without deadlines.

Hepatotoxicity reports in the FDA adverse event reporting system database

This study compared drugs associated with hepatotoxicity in the FDA's FAERS database, finding that mitochondrial mechanisms are a leading cause of drug-induced liver injury. The top four drugs with the highest risk were associated with mitochondrial mechanisms, and older patients and females were more likely to be affected.
