Werner syndrome (WS) is a rare hereditary progeroid syndrome caused by mutations in the WRN gene. Patients frequently develop various age-associated diseases prematurely, often leading to early mortality (≤ 60 years of age). Depletion of nicotinamide adenine dinucleotide (NAD)^(+) has been reported in patients with WS, suggesting a key role in the pathogenesis of WS. NAD^(+) supplementation may improve the condition of WS and other accelerated aging diseases. Therefore, we conducted a...

Resilience is increasingly recognized as a central factor in how older adults adapt to life's inevitable changes, yet many clinicians remain unfamiliar with its practical applications in late life. Drawing on the true story of Cocota, a Brazilian matriarch who lived to be 100, this special article illustrates how resilience is neither a static trait nor limited to mere survival.

The authors administered a survey adapted from the Dutch Functional Abilities List to a nationally representative sample of US adults ages 22 and older, finding that nearly three-quarters of working adults report at least one functional limitation, with an average of nearly six functional limitations per working...
