These simple fitness tests revealed which older adults had the lowest death risk

Objective fitness tests in 13,423 Taiwanese adults aged 65 years or older linked better balance, agility, lower-body strength, and cardiorespiratory fitness with lower all-cause mortality over a median seven years. A multidomain fitness index showed the strongest association, suggesting that simple performance tests may add useful information to conventional geriatric risk assessment.

Coral-inspired scaffold enhances bone repair by reprogramming immune cells

SONFH is one of the leading causes of non-traumatic osteonecrosis. Reported in up to 9%–40% of patients receiving prolonged or high-dose glucocorticoid therapy, the condition progressively weakens the femoral head and can eventually lead to joint collapse, making effective bone repair a major clinical challenge.
