The Relationship Between Urinary Total Polyphenols and the Frailty Phenotype in a Community-Dwelling Older Population: The InCHIANTI Study

M. Urpi-Sarda, C. Andres-Lacueva, M. Rabassa, et al.

J Gerontol A Biol Sci Med Sci. 2015;70(9):1141-7

Studies have suggested that the quality of dietary intake may affect the development of frailty. The authors of this study hypothesized that frailty in older subjects would be associated with dietary total polyphenols (DTP) intake and its biomarker, urinary total polyphenols (UTP). Data obtained shown that an high concentrations of UTP were associated with lower prevalence of frailty and prefrailty in an older community-dwelling population. A polyphenol-rich diet may protect against frailty in older persons.

Effects of physical exercise interventions in frail older adults: a systematic review of randomized controlled trials

C. de Labra, C. Guimaraes-Pinheiro, A. Maseda, et al.

BMC Geriatrics. 2015;15:154

Physical exercise has demonstrated its beneficial effects in reducing the risk of many adverse outcomes, such as frailty. The major goal of this systematic review of randomized, controlled trials (RCTs) was to investigate the benefits of exercise programs in frail elderly people, considering only those studies where frailty had been defined.
This systematic review suggested that frail older adults seemed to benefit from exercise interventions, although the optimal program remains unclear.

Association of habitual dietary resveratrol exposure with the development of frailty in older age: the Invecchiare in Chianti study

M. Rabassa, R. Zamora-Ros, M. Urpi-Sarda, et al.

Am J Clin Nutr. 2015;102:1534–42

Resveratrol may play a protective role against the frailty syndrome (FS) because of its antioxidant and anti-inflammatory properties. This study has prospectively evaluated the association between habitual dietary resveratrol exposure and the development of FS after 3-, 6-, and 9-years follow-up periods in a community-dwelling older population. This study has shown that higher habitual dietary resveratrol exposure was associated with lower risk of older community dwellers developing FS during the first 3 years of follow-up but not after longer follow-up periods.

Predictive validity of a two-step tool to map frailty in primary care

J.A.L. van Kempen, H.J. Schers, I. Philp, et al.

BMC Medicine. 2015;13:287

EASY-Care Two step Older people Screening (EASY-Care TOS) is a stepped approach to identify frail older people at risk for negative health outcomes in primary care, and makes use of General Practitioners’ (GPs) readily-available information. This study aimed to determine the predictive value of EASY-Care TOS for negative health outcomes within the year from assessment. GPs applying the EASY-Care TOS procedure, where they only perform additional assessment when they judge this as necessary, can efficiently predict negative health outcomes in their older populations. Moreover, this evaluation is almost as accurate as a complete specialist comprehensive geriatric assessment (CGA).

Is Trunk Posture in Walking a Better Marker than Gait Speed in Predicting Decline in Function and Subsequent Frailty?

R.A. Merchant, S. Banerji, G. Singh, E. Chew, et al.

J Am Med Dir Assoc. 2016;17(1):65-70

Older adults are known to compensate well for declining physiological reserve through environmental modification and posture adaptation. This study aimed to analyze and identify significant posture adaptation in older adults that is required to maintain gait speed in the face of increasing vulnerability.
Data of this study suggest that identifying trunk posture adaptation before the onset of decline in gait speed will help in planning interventions in the at-risk community-dwelling older adults even before gait speed declines.

Prevalence and risk factors of sarcopenia among adults living in nursing homes

H. E. Senior, T. R. Henwood, E. M. Beller, et al.

Maturitas 2015; 82: 418–423

Sarcopenia is a progressive loss of skeletal muscle and muscle function, with significant health and disability consequences for older adults. This study was aimed to evaluate the prevalence and risk factors of sarcopenia among older residential aged care adults using the European Working Group on Sarcopenia in Older People (EWGSOP) criteria.

Effects of a vitamin D and leucine-enriched whey protein nutritional supplement on measures of sarcopenia in older adults, the PROVIDE study: a randomized, double-blind, placebo-controlled trial

J.M. Bauer, S. Verlaan, I. Bautmans, et al.

J Am Med Dir Assoc.2015;16:740-747

This study was a multicenter, randomized, controlled, double-blind, 2 parallel-group trial among 380 sarcopenic primarily independent-living older adults. The aim of the study was to test the hypothesis that a specific oral nutritional supplement can result in improvements in measures of sarcopenia. Improvements in muscle mass and lower-extremity function were observed, suggesting that nutritional supplementation alone might benefit geriatric patients.

Nutritional, Physical, Cognitive and Combination Interventions and Frailty Reversal Among Older Adults: A Randomized Controlled Trial

T. P. Ng, L. Feng, M.S. Nyunt, et al.

Am J Med.2015;128:1225-1236.e1

This study aimed to assess the reversibility of frailty in 246 community-living prefrail and frail older people in Singapore (mean age: 70 years). Participants were randomly assigned to 5 different 6-month interventions: nutritional supplementation, physical training, cognitive training, combination treatment and usual care control. Frailty score, body mass index, knee extension strength, gait speed, energy/vitality, physical activity levels and secondary outcomes (activities of daily living dependency, hospitalization and falls) were assessed at 0, 3, 6 and 12 months.
