BackgroundIt is important to establish whether frailty among older individuals reversible with nutritional, physical, or cognitive interventions, singly in combination. We compared the effects of 6-month-duration interventions nutritional supplementation, physical training, and combination treatment vs control reducing community-dwelling prefrail frail persons.MethodsWe conducted a parallel group, randomized controlled trial community-living old adults Singapore. The participants' mean age...

Abstract Background Although cerebral small‐vessel disease has been implicated in the development of Alzheimer's (AD), microcirculation is difficult to visualize directly vivo. Because retina provides a noninvasive window assess microcirculation, we determined whether quantitatively measured retinal microvascular parameters are associated with AD. Methods We conducted case‐control study (case:control matching ≈ 1:2). Retinal photographs were analyzed using computer program, and spectrum...
