Background: The Short Physical Performance Battery (SPPB) is a well-established tool to assess lower extremity physical performance status. Its predictive ability for all-cause mortality has been sparsely reported, but with conflicting results in different subsets of participants. The aim of this study was to perform a meta-analysis investigating the relationship between SPPB score and all-cause mortality.

Our prospective study in an unselected geriatric population demonstrates superior prognostic utility of central compared with brachial BP.

Sarcopenia, the age-dependent loss of muscle mass and function, is a common condition among older adults, and is associated with several adverse health outcomes. Owing to the impact of sarcopenia on quality of life, disability and mortality, a greater awareness is necessary in order to correctly identify the condition both in community and geriatric settings. Research on sarcopenia prevention and treatment is developing quickly, but many questions are still unanswered. The core of the sarcopenia condition involves quantitative and qualitative losses of skeletal muscle. These two dimensions should therefore be considered when designing and testing preventive and therapeutic interventions. The recently released operationalization of sarcopenia by the Foundation for the National Institutes of Health (FNIH) Sarcopenia Project allows for the framing of an objective, standardized, and clinically relevant condition, which should facilitate its translation into the clinical arena as well as its adoption by public health and regulatory agencies. Such a conceptualization might eventually encourage key stakeholders to combine their efforts in approaching the sarcopenia condition. Bearing these considerations in mind, the "Sarcopenia and Physical fRailty IN older people: multi-componenT Treatment strategies" project has operationalized a specific condition, named physical frailty and sarcopenia (PF&S), characterized by the combination of low physical performance (based on the Short Physical Performance Battery) and low muscle mass (according to the FNIH cut-points). A randomized controlled trial will be conducted to evaluate the efficacy of a multi-component intervention for preventing mobility disability and other adverse health outcomes in older adults with PF&S.

This study examines and compares the effect of aerobic and resistance exercise on emotional and physical function among older persons with initially high or low depressive symptomatology. Data are from the Fitness, Arthritis and Seniors Trial, a trial among 439 persons 60 years or older with knee osteoarthritis randomized to health education (control), resistance exercise, or aerobic exercise groups. Depressive symptoms (assessed by the Center for Epidemiologic Studies--Depression scale) and physical function (disability, walking speed, and pain) were assessed at baseline and after 3, 9, and 18 months. Compared with results for the control group, aerobic exercise significantly lowered depressive symptoms over time. No such effect was observed for resistance exercise. The reduction in depressive symptoms with aerobic exercise was found both among the 98 participants with initially high depressive symptomatology and among the 340 participants with initially low depressive symptomatology and was the strongest for the most compliant persons. Aerobic and resistance exercise significantly reduced disability and pain and increased walking speed both, and to an equal extent, in persons with high depressive symptomatology and persons with low depressive symptomatology.

Serum uric acid independently predicts cardiovascular events in older persons with isolated systolic hypertension. Monitoring serum uric acid change during diuretic treatment may help to identify patients who will most benefit from treatment.

The identification of cost-effective interventions that improve the health status and prevent disability in old age is one of the most important public health challenges. Regular physical activity is the only intervention that has consistently been shown to improve functional health and energy balance and to reduce the risk of cardiovascular disease, stroke, diabetes, several cancers, depression and falls. In advanced age, physical activity is also effective at mitigating sarcopenia, restoring robustness, and preventing/delaying the development of disability. On the other hand, physical inactivity is recognized as one of the leading causes of several chronic degenerative diseases and is also a major contributing factor to sarcopenia and functional disability. This compelling evidence has prompted the World Health Organization to recommend engaging in regular physical activity throughout one's life course. The present review summarizes the available evidence in support of physical activity as a remedy against physical frailty and sarcopenia. The relevant pathways through which the benefits of physical activity are conveyed are also discussed.

Background-Observational studies suggest that open visiting policies are preferred by most patients and visitors in intensive care units (ICUs), but no randomized trial has compared the safety and health outcomes of unrestrictive (UVP) and restrictive (RVP) visiting policies. The aim of this pilot, randomized trial was to compare the complications associated with UVP (single visitor with frequency and duration chosen by patient) and RVP (single visitor for 30 minutes twice a day). Methods and Results-Two-month sequences of the 2 visiting policies were randomly alternated for 2 years in a 6-bed ICU, with 226 patients enrolled (RVP/UVP, nϭ115/111). Environmental microbial contamination, septic and cardiovascular complications, emotional profile, and stress hormones response were systematically assessed. Patients admitted during the randomly scheduled periods of UVP received more frequent (3.2Ϯ0.2 versus 2.0Ϯ0.0 visits per day, meanϮSEM) and longer (2.6Ϯ0.2 versus 1.0Ϯ0.0 h/d) visits (PϽ0.001 for both comparisons). Despite significantly higher environmental microbial contamination during the UVP periods, septic complications were similar in the 2 periods. The risk of cardiocirculatory complications was 2-fold (odds ratio 2.0; 95% CI, 1.1 to 3.5; Pϭ0.03) in the RVP periods, which were also associated with a nonsignificantly higher mortality rate (5.2% versus 1.8%; Pϭ0.28). The UVP was associated with a greater reduction in anxiety score and a significantly lower increase in thyroid stimulating hormone from admission to discharge. Conclusions-Despite
