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.

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.

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.

Serum markers of inflammation and oxidative stress in sarcopenia

B. Can, O. Kara, M.C. Kizilarslanoglu, et al.

Aging Clin Exp Res. 2017;29(4):745-752

The aim of the study was to evaluate the relationship between sarcopenia and biomarkers that may be involved in its pathogenesis and hence allow early detection. The present study demonstrated an association of sarcopenia with inflammatory markers CRP, erythrocyte sedimentation rate and adiponectin.

Neuromuscular function in different stages of sarcopenia

T. Morat, K.J. Gilmore and C.L. Rice

Exp Gerontol. 2016;81:28-36

This study applied the screening tool developed by the European Working Group on Sarcopenia in Older People (EWGSOP) on seniors aged over 65years and concurrently tested various laboratory-based indices of neuromuscular function. Based on gait speed, handgrip strength and muscle mass all subjects were categorized into one of the three conceptual sarcopenia stages (pre-sarcopenia, sarcopenia, severe sarcopenia). The laboratory tests found neuromuscular differences among the 3 groups which generally supported the classification scheme and helped to illustrate some key factors that could explain differences in functional capacities.

High Levels of Heavy Metals Increase the Prevalence of Sarcopenia in the Elderly Population

J.I. Yoo, Y.C. Ha, Y.K. Lee, et al.

J Bone Metab. 2016;23(2):101-9

Despite increasing concern regarding health problems as a result of environmental pollutants, no association of toxic heavy metals with sarcopenia has been demonstrated in the general population. In this article the association of heavy metals, including lead, mercury and cadmium, with sarcopenia in the Korean population was investigated. This study demonstrates that high levels of blood lead, mercury and cadmium increase the prevalence of sarcopenia in both genders of elderly populations.

Fried frailty phenotype assessment components as applied to geriatric inpatients

J. Bieniek , K. Wilczyński and J. Szewieczek

Clin Interv Aging. 2016;11:453-9

The aim of this article was to assess the usefulness and limitations of Fried frailty phenotype criteria in geriatric inpatients, characterized by comorbidity and functional impairments, and to estimate the frailty phenotype prevalence in this group. Data obtained suggest that Fried frailty phenotype criteria can useful for geriatric inpatient assessment, despite diagnostic limitations

Physical Activity Performed in the Evening Increases the Overnight Muscle Protein Synthetic Response to Presleep Protein Ingestion in Older Men

A.M. Holwerda, I.W. Kouw, J. Trommelen, et al.

J Nutr. 2016;146(7):1307-14

The present study assessed whether physical activity performed in the evening can augment the overnight muscle protein synthetic response to presleep protein ingestion in older men. Physical activity performed in the evening augments the overnight muscle protein synthetic response to presleep protein ingestion and allows more of the ingested protein-derived amino acids to be used for de novo muscle protein synthesis during overnight sleep in older men.

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 clinical frailty scale predicts functional decline and mortality when used by junior medical staff: a prospective cohort study

K.J. Gregorevic, R.E. Hubbard, W.K. Lim, et al.

BMC Geriatr. 2016;16(1):117

The objective of this study is to determine whether the clinical frailty scale (CFS) can be used to identify patient baseline frailty status in the acute general medical setting when used by junior medical staff using information obtained on routine clinical assessment. A high proportion of eligible patients had the frailty measure completed, demonstrating the acceptability of the CFS to clinicians. Despite lack of training for medical staff, increasing frailty was correlated with functional decline and mortality supporting the validity of the CFS as a frailty screening tool for clinicians.
