Maintenance of Physical Function 1 Year After Exercise Intervention in At-Risk Older Adults: Follow-up From the LIFE Study

R.M. Henderson, M.E. Miller, R.A. Fielding, et al.

J Gerontol A Biol Sci Med Sci. 2018;73(5):688-694

Structured physical activity interventions delay the onset of disability for at-risk older adults. However, it is not known if at-risk older adults continue to participate in physical activity or maintain mobility benefits after cessation of structured intervention.

Impact of Sarcopenia on One-Year Mortality among Older Hospitalized Patients with Impaired Mobility

M. Pourhassan, K. Norman, M.J. Müller, et al.

J Frailty Aging. 2018;7(1):40-46

The aim of the present study was to investigate the associations between sarcopenia and 1-year mortality in a prospectively recruited sample of geriatric inpatients with different mobility and dependency status.

Risk of Malnutrition Evaluated by Mini Nutritional Assessment and Sarcopenia in Noninstitutionalized Elderly People

I. Liguori, F. Curcio, G. Russo, et al.

Nutr Clin Pract. 2018 Feb 13. doi: 10.1002/ncp.10022. [Epub ahead of print]

Malnutrition indices and muscle mass and strength in the elderly are poorly investigated. Moreover, malnutrition seems to be one of the more important factors in the cause of sarcopenia.

The presence of sarcopenia and its relationship with malnutrition indices were studied in noninstitutionalized elderly people who underwent Comprehensive Geriatric Assessment (CGA).

Sex differences in the effect of fish-oil supplementation on the adaptive response to resistance exercise training in older people: a randomized controlled trial

M. Da Boit, R. Sibson, S. Sivasubramaniam, et al.

Am J Clin Nutr. 2017;105(1):151-158

Long-chain n-3 PUFA supplementation augments the increases in muscle function and quality in older women but not in older men after resistance exercise training.

Potential roles of vitamin E in age-related changes in skeletal muscle health

E. Chung, H. Mo, S. Wang, et al.

Nutr Res. 2018;49:23-36

Current literature suggests that vitamin E molecules (α-, β-, γ-, δ-tocopherols and the corresponding tocotrienols) with their antioxidant and anti-inflammatory capabilities may mitigate age-associated skeletal dysfunction and enhance muscle regeneration, thus attenuating sarcopenia.

Cross-sectional associations of dietary and circulating magnesium with skeletal muscle mass in the EPIC-Norfolk cohort

R.P.G. Hayhoe, M.A.H. Lentjes, A.A. Mulligan, et al.

Clin Nutr. 2018 Jan 30. pii: S0261-5614(18)30015-3. doi: 10.1016/j.clnu.2018.01.014. [Epub ahead of print]

This study demonstrated strong associations between dietary magnesium intake, but not serum magnesium levels, and indices of skeletal muscle mass in a UK population of middle to older-aged adults, highlighting the likely importance of dietary magnesium for optimal muscle health in this population.

Prevalence and Incidence of Frailty in Community-Dwelling Older People: Beijing Longitudinal Study of Aging II

Z. Zheng, S. Guan, H. Ding, et al.

J Am Geriatr Soc. 2016;64(6):1281-6

The objective of this secondary analysis of a prospective cohort study was to estimate the prevalence and incidence of frailty and evaluate the effect of frailty on adverse outcomes in 10,039 Chinese elderly adults (≥55 years). A 12.3% prevalence and a 13% incidence of frailty was demonstrated in community-dwelling Chinese older adults.

Frailty as a Predictor of Acute Kidney Injury in Hospitalized Elderly Patients: A Single Center, Retrospective Cohort Study

S.H. Baek, S.W. Lee, S.W. Kim, et al.

PLoS One. 2016;11(6):e0156444

This study aimed at determining the effect of frailty as a predictor of acute kidney injury (AKI). 533 hospitalized elderly patients (aged ≥ 65 years) were retrospectively enrolled.

Data obtained suggest that frailty may independently predict the development of AKI and adverse outcomes in geriatric inpatients.

Estimation of sarcopenia prevalence using various assessment tools

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

Experimental Gerontology.2015;61:31-7

This study aims to evaluate the prevalence of sarcopenia in relation to the assessment tool used in the measurement of the variables related to muscle mass, muscle strength and physical performance. The results obtained showed that the prevalence of sarcopenia varies between 8.4% and 27.6% in relation to the method used. Furthermore, it was observed that the bioelectrical impedance analysis (BIA) tends to overestimate muscle mass compared to the X-ray absorptiometry dual energy (DXA). As regards the muscle strength, it is observed that the pneumatic dynamometer allowed to diagnose the double of the sarcopenic subjects compared to hydraulic dynamometer.
