Cover Story: Frailty is a geriatric syndrome that increases the risk of morbidity, disability, and death. Perturbations in amino acid metabolism contribute to muscle loss and functional decline associated with frailty and diabetes. In the cover page study, amino acid profiles of frail older adults with sarcopenia, frail older individuals with type 2 diabetes mellitus, and controls were characterized and analyzed using multivariate statistical analysis. Specific amino acid profiles were found to be associated with distinct types of frailty. Pathways potentially involved in the pathophysiology of different frailty phenotypes were also identified, which included muscle energy and interorgan metabolic regulation, nitric oxide metabolism, and oxidative stress. Amino acid profiling may serve as a valuable tool for frailty biomarker discovery. View this paper
