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).

Myostatin antibody (LY2495655) in older weak fallers: a proof-of-concept, randomised, phase 2 trial

C. Becker, S.R. Lord, S.A. Studenski, et al.

Lancet Diabetes Endocrinol. 2015;3:948-957

Myostatin inhibits skeletal muscle growth. The humanised monoclonal antibody LY2495655 (LY) binds and neutralises myostatin. This study aimed to test whether LY increases appendicular lean body mass (aLBM) and improves physical performance in older individuals who have had recent falls and low muscle strength and power. At 24 weeks, the least-squares mean change in aLBM was -0.123 kg in the placebo group and 0.303 kg in the LY group (P < 0.0001). This results show LY treatment increases lean mass and might improve functional measures of muscle power.

Association of Hearing Impairment With Incident Frailty and Falls in Older Adults

R.J. Kamil, J. Betz, B. Brott Powers, et al.

Journal of Aging and Health.2016;28(4):644-60

The hearing impairment (HI) is highly prevalent but undertreated in older adults and, although it contributes to frailty risk, it remains poorly studied. This study aimed at determining whether HI in older adults is associated with the development of frailty and falls. This study demonstrate that moderate or greater HI is associated with increased risk of developing frailty and that HI is associated with an increased annual risk of falling.

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.

The impact of sleep on age-related sarcopenia: Possible connections and clinical implications

R.D. Piovezan, J. Abucham, R.V. Dos Santos, et al.

Ageing Res Rev. 2015;23(Pt B):210-20

Reductions in duration and quality of sleep and increases in prevalence of circadian rhythm and sleep disorders with age favor proteolysis, modify body composition and increase the risk of insulin resistance, all of which have been associated with sarcopenia. Therapeutic approaches targeting sleep disturbances to normalize circadian rhythms and sleep homeostasis may represent a novel strategy to preserve or recover muscle health in older adults.

Energetics of Aging and Frailty: The FRADEA Study

P. Abizanda, L. Romero, P.M. Sánchez-Jurado, et al.

J Gerontol A Biol Sci Med Sci. 2016;71(6):787-96

Resting metabolic rate (RMR) and total daily energy expenditure (TDEE) decrease with aging, but it is not known whether frailty modulates this association. Authors hypothesize that RMR and TDEE values are similar between younger and older nonfrail adults, whereas they are lower in older prefrail and frail compared with younger adults. This study shows that frailty status modulates the energy requirements of aging. Frail and prefrail older adults present lower eRMR than nonfrail adults.

Dairy Consumption and Risk of Frailty in Older Adults: A Prospective Cohort Study

A. Lana, F. Rodriguez-Artalejo and E. Lopez-Garcia

J Am Geriatr Soc. 2015;63(9):1852-60

Some studies have found positive effects of dairy consumption in older people, but the evidence base for this recommendation remains scarce. This study aimed to examining the association between consumption of dairy products and risk of frailty in community-dwelling older adults. Data obtained shown that higher consumption of low-fat milk and yogurt are associated with lower risk of frailty and, specifically, lower risk of slow walking speed and weight loss.

Caloric restriction and aerobic exercise in sarcopenic and non-sarcopenic obese women: an observational and retrospective study

S. Barbat-Artigas, S. Garnier, S. Joffroy, et al.

J Cachexia Sarcopenia Muscle. 2016;7(3):284-9

The objective of this observational and retrospective study was to verify the effect of a mixed weight loss programme combining caloric restriction and exercise on body composition, and lipid-lipoprotein profile of obese women according to their sarcopenic status. Data obtained suggest that a short weight loss programme combining caloric restriction and aerobic exercise may significantly reduce fat mass and improve lipid-lipoprotein profile in obese women, independently of their sarcopenic status. Such programmes may have deleterious effects on lean mass in non-sarcopenic obese subjects, only.

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.

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.
