Background: The decline in lean mass, observed in older people, has been frequently associated with frailty. This assumption has scarcely been assessed. This study explored the association between current proposed definitions of low lean mass and the Fried phenotype of frailty.

Although innate defenses exist for limiting the occurrence of such detrimental effects, their ability to counteract the continuous and large production of reactive oxygen species becomes increasingly inefficient with aging. In this context, interventions aimed at preserving the homeostatic balance between oxidant production and antioxidant protection may be beneficial on the pathophysiological modifications and clinical manifestations featuring the aging process.

Although equally considered in the computation of the frailty phenotype score, each of the components may present a specific and different weight in clinical practice. The objective of this study was to estimate the weight of each frailty phenotype component in terms of age-related deficit accumulation, defined according to the frailty index (FI) proposed by Rockwood and colleagues.

Indeed, extended lifetime involves maintaining function and the capacity of living independently. Sarcopenia and physical frailty are both highly relevant entities with regards to functionality and autonomy of older adults.

Recent Findings: Fourteen studies were retained for the present review. No randomized controlled trial was found.
Purpose Of Review: The scope of the current study is to provide an updated, comprehensive review of the recent literature (past 12 months), examining the role of nutrition and exercise on frailty.
Recent Findings: Over the past 12 months, seven studies with different designs explored the relationship between nutrition and frailty, four examined the role of exercise on frailty, and only one study investigated the combination of the two interventions. The only study combining an exercise program with a nutritional consultation reported a short-term (3 months) improvement of the frailty status.
The integration of frailty measures in clinical practice is crucial for the development of interventions against disabling conditions in older persons. The frailty phenotype (proposed and validated by Fried and colleagues in the Cardiovascular Health Study) and the Frailty Index (proposed and validated by Rockwood and colleagues in the Canadian Study of Health and Aging) represent the most known operational definitions of frailty in older persons. Unfortunately, they are often wrongly considered as alternatives and/or substitutables.

Design: Four-year prospective multicenter cohort study with a biannual assessment.
Setting: Memory clinics from 16 university hospitals in France.
Background: Cognitive dysfunction and changes in body composition share common pathophysiological pathways. The aim of the present paper was to evaluate whether changes in appendicular muscle mass (AMM) and fat mass (FM) are associated factors with an increased risk of cognitive dysfunction in community-dwelling older women.
Methods: A nested case-control study was performed in 181 women aged 75 years and older from a subsample of the Epidemiologie de l'Osteoporose participants from Toulouse.
Sarcopenia, the age-related skeletal muscle decline, is associated with relevant clinical and socioeconomic negative outcomes in older persons. The study of this phenomenon and the development of preventive/therapeutic strategies represent public health priorities. The present document reports the results of a recent meeting of the International Working Group on Sarcopenia (a task force consisting of geriatricians and scientists from academia and industry) held on June 7-8, 2011 in Toulouse (France).

Design: A 2-year prospective, observational cohort study.
Setting: Nineteen memory centers across France.
