Health Digest: Genetic Testing, Heart Failure, and More

· 8 source(s)

Today's health news covers age-based genetic testing gaps, a fat-storing gene linked to anorexia, barriers to micronutrient-rich diets, a protective airway bacterium, rising heart failure deaths in younger Americans, muscle regeneration clues, short-term memory mechanisms, and a pediatric pain treatment.

A new study suggests that current age-based genetic testing guidelines for cancer patients may miss the majority of inherited gene variants. Medical Xpress reports that germline genetic screening can identify inherited alterations that predispose individuals to cancer and flag risk in family members, but age-based criteria may fail to detect many carriers.

Separately, Medical Xpress reports that a gene primarily active in fat and muscle could increase susceptibility to anorexia nervosa, a psychiatric disorder with one of the highest mortality rates. The finding points to a possible biological contributor to the eating disorder.

A study on dietary barriers reveals that having enough food does not guarantee a nutritionally adequate diet. Medical Xpress reports that vulnerable consumers face multiple obstacles beyond food prices in accessing micronutrient-rich foods.

Research from the University of Colorado Anschutz, covered by Medical Xpress, indicates that a common bacterium in the mouth and airways may help the lungs defend against pneumonia. The finding suggests a potential role for this microbe in lung immunity.

Heart failure deaths in the U.S. have doubled among younger and middle-aged adults, according to a new report highlighted by Medical Xpress. The steady increase is fueled by rising mortality in these age groups.

Medical Xpress also reports that the protein LMOD1 offers new clues to muscle regeneration. The protein appears to play a role in the activation of muscle stem cells after injury, which is essential for repairing skeletal muscle.

In neuroscience, a fruit fly study led by NYU Langone Health has confirmed a long-standing suspicion about how the brain encodes short-term memories. Medical Xpress reports that the research reveals neural gates that switch on short-term memory.

Finally, a study presented at the European Emergency Medicine Congress in Paris found that intranasal sufentanil-ketamine is fast-acting, well tolerated, and effective for acute pain in pediatric emergency patients. Medical Xpress reports the treatment could offer a rapid option for pain relief in children.
