Blood-cell mutation patterns linked to cancer progression

A yearly rise of at least 7.5% in mutated gene copies’ share best predicted cancer progression among patients with unexplained low counts of certain white blood cells.A yearly rise of at least 7.5% in mutated gene copies’ share best predicted cancer progression among patients with unexplained low counts of certain white blood cells.

Older adults with muscle weakness had less steady force

A measure of force variability rose about 35% when adults with muscle weakness subtracted numbers during ankle contractions, compared with the muscle task alone.A measure of force variability rose about 35% when adults with muscle weakness subtracted numbers during ankle contractions, compared with the muscle task alone.

Heatwaves linked to declining intrinsic capacity in older adults

Each additional heatwave day was linked to a relative risk ratio of 1.035 for a low-declining intrinsic capacity trajectory, while cold spells showed no association.Each additional heatwave day was linked to a relative risk ratio of 1.035 for a low-declining intrinsic capacity trajectory, while cold spells showed no association.
