Sarcopenia is an independent risk factor of dysphagia in hospitalized older people

Maeda and J. Akagi

Geriatr Gerontol Int. 2016 ;16(4):515-21

The present study investigated the prevalence of dysphagia among patients with sarcopenia, and the association between the two conditions. On 224 older adults, the prevalences of sarcopenia and dysphagia were 76.8% and 30.0%, respectively and it was shown that sarcopenia is an independent risk factor for dysphagia among older individuals.

What is a Clinically Meaningful Improvement in Leg-Extensor Power for Mobility-limited Older Adults?

D.R. Kirn, K.F. Reid, C. Hau, et al.

J Gerontol A Biol Sci Med Sci. 2016;71(5):632-6

The purpose of this study is to establish the minimal clinically important improvement (MCII) and substantial improvement (SI) for leg-extensor power and muscle contraction velocity in mobility-limited older adults.

This is the first study to establish a clinically meaningful improvement of leg-extensor power (9%-10%) and velocity (6%-7%) in mobility-limited older adults

Comparison of Handgrip and Leg Extension Strength in Predicting Slow Gait Speed in Older Adults

M.S. Fragala, D.E. Alley, M.D. Shardell, et al.

J Am Geriatr Soc. 2016;64:144–150

This study aimed at comparing the relative predictive power of handgrip and leg extension strength in predicting slow walking.

Results suggest that handgrip strength may be an adequate measure to predict physical function whereas leg extension strength is only a slightly better predictor of slow gait speed.

Macronutrients Intake and Incident Frailty in Older Adults: A Prospective Cohort Study

H. Sandoval-Insausti, R.F. Pérez-Tasigchana, E. López-García, et al.

J Gerontol A Biol Sci Med Sci.2016;71(10):1329-34

This study examined the association of protein and other macronutrient intake with the risk of frailty in older adults. Authors concluded that the intake of total protein, animal protein, and MUFAs was inversely associated with incident frailty. Promoting the intake of these nutrients might reduce frailty.

Development and validation of an electronic frailty index using routine primary care electronic health record data

A. Clegg, C. Bates, J. Young, R.Ryan, et al.

Age and Ageing. 2016;45(3):353-60

International guidelines recommend routine identification of frailty to provide evidence-based treatment, but currently available tools require additional resource. This retrospective cohort study wants to develop and validate an electronic frailty index (eFI), using routinely available primary care electronic health record data.

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, 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.

Quality of life and physical components linked to sarcopenia: The SarcoPhAge study

C. Beaudart, J.Y. Reginster, J. Petermans, et al.

Experimental Gerontology. 2015;69: 103–110

The SarcoPhAge project is an ongoing longitudinal study following community-dwelling elderly subjects; the aim of this study is to assess prevalence of sarcopenia and clinical components using the diagnosis algorithm developed by the European Working Group on Sarcopenia in Older People (EWGSOP). The authors concluded that sarcopenia seems to be associated with many harmful clinical components (for example frailty and polipharmacy) making this geriatric syndrome a real public health burden.
