Compared with those who spent most of their time in a single room, people with heart failure with preserved ejection fraction (HFpEF) who were able to travel outside of their home without assistance were significantly less likely to be hospitalized or die within a year, according to a new study. The findings underscore the value of supporting holistic care and encouraging people with heart failure to maintain an active lifestyle and engage with others in their community to the extent possible, researchers said.

Researchers have found a unique molecular signature and genes in the orbitofrontal cortex associated with heroin-seeking behavior. A preclinical rodent model implicated a gene called Shisa7 as the key predictor. A new study provides valuable insights into the neurobiological mechanisms underlying heroin addiction and may have implications for the development of innovative strategies to combat the ongoing opioid epidemic.
