Health-record model predicted diagnoses across health systems

At a threshold that left 95% of disease-free patients unflagged, flagged patients were up to eight times more likely than unselected patients to receive diagnoses within…At a threshold that left 95% of disease-free patients unflagged, flagged patients were up to eight times more likely than unselected patients to receive diagnoses within a year.

Frailty links to distinct muscle and protein changes by sex

In 208 older adults, frailty was linked to muscle and bone loss in females, while males showed lower leg strength and altered muscle protein breakdown.In 208 older adults, frailty was linked to muscle and bone loss in females, while males showed lower leg strength and altered muscle protein breakdown.

Group differences in muscle health and exercise capacity in the whole group, males, and females; peak leg torque extension (a), 6MWT distance (d), and lean soft tissue (g) in whole group, and peak…

Neighborhood deprivation linked to brain amyloid buildup

In an observational study of 1,110 people, living in more deprived areas was associated with lower cognitive scores and more amyloid build-up in unimpaired brains.In an observational study of 1,110 people, living in more deprived areas was associated with lower cognitive scores and more amyloid build-up in unimpaired brains.
