BACKGROUND: Fried and colleagues described a frailty phenotype measured in the Cardiovascular Health Study (CHS). This phenotype is manifest when ≥3 of the following are present: low grip strength, low energy, slowed waking speed, low physical activity, or unintentional weight loss. We sought to approximate frailty phenotype using only administrative claims data to enable frailty to be assessed without physical performance measures. STUDY DESIGN: We used the CHS cohort data linked to participants Medicare claims...

BACKGROUND: For investigating the relationship of frailty with physical, psychological, and social conditions on pathways, the frailty definition should ideally exclude these conditions. Based on the frailty phenotype, 2 candidate physical frailty specifications or instruments with 3 indicators, namely slowness, weakness, and exhaustion, and 4 indicators with addition of weight loss were previously developed, and had their construct and concurrent validity demonstrated. OBJECTIVE: This study seeks to evaluate the predictive validity of 2 candidate physical frailty specifications with respect to death, functional impairment, and poor quality of life in older people...

Human aging is characterized by both physical and physiological frailty that profoundly affects the immune system. In this context aging is associated with declines in adaptive and innate immunity established as immunosenescence. Immunosenescence is a new concept that reflects the age-associated restructuring changes of innate and adaptive immune functions. Thus elderly individuals usually present chronic low-level inflammation, higher infection rates and chronic diseases. A study of alterations in the immune system during aging could provide a potentially useful biomarker for the evaluation of immune senescence treatment...

BACKGROUND: Cirrhosis is characterized by muscle wasting, malnutrition, and functional decline that confer excess mortality not well quantified by the MELDNa score. We aimed to develop a frailty index to capture these extrahepatic complications of cirrhosis and enhance mortality prediction in cirrhotics. METHODS: Consecutive outpatients listed for LT at a single transplant center without MELD exceptions were assessed with candidate frailty measures. Best subset selection analyses with Cox regression identified subsets of frailty measures that predicted waitlist mortality (=death or delisting due to sickness)...

Sarcopenia is an age-related syndrome characterised by progressive and generalised loss of skeletal muscle mass and strength; it is a major contributor to the risk of physical frailty, functional impairment in older people, poor health-related quality of life and premature death. Many different definitions have been used to describe sarcopenia and have resulted in varying estimates of prevalence of the condition. The most recent attempts of definitions have tried to integrate information on muscle mass, strength and physical function and provide a definition that is useful in both research and clinical settings...

Sarcopenia, the age-dependent loss of muscle mass and function/strength, is increasingly recognized as a major risk factor for adverse outcomes in frail older people. As such, the skeletal muscle is a relevant target for interventions aimed at preventing or postponing the occurrence of negative health-related events in late life. The association among physical inactivity, insufficient intake of energy and protein, and poor muscle health in older adults suggests that physical exercise and targeted nutritional supplementation may offer substantial therapeutic gain against sarcopenia and its negative correlates...

Apolipoproteins play a crucial role in lipid metabolism with implications in cardiovascular disease, obesity, diabetes, Alzheimer's disease, and longevity. We quantified 7 apolipoproteins in plasma in 1067 individuals aged 56-105 using immunoassays and explored relationships with APOE polymorphism ε2/3/4, vascular health, frailty, and cognition. ApoA1, ApoA2, ApoB, ApoC3, ApoE, ApoH, and ApoJ decreased from mid-life, although ApoE and ApoJ had U-shaped trends. Centenarians had the highest ApoE levels and the lowest frequency of APOE ε4 allele relative to younger groups...

BACKGROUND: Frailty is a state of increased vulnerability to poor resolution of homeostasis as a consequence of age-related decreased physiological reserves. Although physical frailty and cognitive impairment have been shown to be associated, evidence on the prevalence of frailty in Alzheimer's disease is scarce. OBJECTIVE: To conduct a systematic review on the prevalence of frailty and to combine the data to synthesize the pooled prevalence of physical frailty among patients with Alzheimer's disease...

Oropharyngeal dysphagia (OD) is a condition recognized by the World Health Organization and defined as the difficulty or inability to move a bolus safely and effectively from the oral cavity to the esophagus, and can include aspirations, choking, and residue. OD is pandemic among different phenotypes of older people, affecting between 27% and 91% of the population 70 years or older. Although OD can be diagnosed by well-defined clinical methods and complementary explorations, in the clinical setting OD is seldom systematically screened and treated, and awareness among the medical/geriatric community is scarce...

OBJECTIVE: It is clear that each trend of kyphosis with increased age and the ability to eat firm foods with the back teeth (chewing ability) has a strong influence on both the physical and mental condition of older people. Thus, this study aimed to examine whether the combination of kyphosis and chewing disorders was associated with mortality or the need for care under the new long-term care insurance (LTCI) service requirement, over 3 years in community-dwelling older Japanese adults...

Frailty is a distinct phenotype that is highly prevalent in chronic kidney disease (CKD) and appears to be more prevalent with decreasing glomerular filtration rate. Exercise training or intervention to increase physical activity may ameliorate poor physical functioning and frailty, and even may improve survival in patients with CKD. Although exercise interventions improve outcomes across the spectrum of CKD, including patients treated with dialysis, patients treated with dialysis face barriers to exercise that patients with predialysis CKD do not...

Frailty is a geriatric syndrome that is an important public health problem for the older adults living in the USA. Although several methods have been developed to measure frailty in humans, we have very little understanding of its etiology. Because the molecular basis of frailty is poorly understood, mouse models would be of great value in determining which pathways contribute to the development of frailty. More importantly, mouse models would be critical in testing potential therapies to treat and possibly prevent frailty...

OBJECTIVE: Epidemiologic evidence on the potential effects of dietary acid load on frailty is lacking. This cross-sectional study examined the association between dietary acid load and frailty. METHODS: This study was based on self-reported data obtained from 2176 Japanese women aged 65-94 years. Dietary acid load was characterized as potential renal acid load (PRAL) and net endogenous acid production (NEAP), based on information on nutrient intake, obtained from a validated brief diet history questionnaire...

Obesity has been associated with higher risk of frailty in older adults, but the pathophysiological mechanisms are unclear. No previous study has examined the association between leptin, an adipokine, and the risk of frailty in older adults, and whether this association could be explained by insulin resistance or chronic inflammation. Data were taken from 1,573 individuals without diabetes mellitus, aged ≥60 years, from the Seniors-ENRICA cohort. In 2008-2010, leptin, the homeostasis model assessment of insulin resistance (HOMA-IR) and C-reactive protein (CRP) were measured...
