Targeting mitochondrial quality control for treating sarcopenia: lessons from physical exercise

A. Picca, R. Calvani, C. Leeuwenburgh, et al.

Expert Opin Ther Targets. 2019;23(2):153-160

We discuss the evidence that points to mitochondrial dysfunction having a causative role in sarcopenia and the mechanisms involved in the accumulation of damaged mitochondria in the aged muscle. We also discuss the effects of physical exercise on mitochondrial quality control and muscle health in advanced age.

Beta-hydroxy-beta-methylbutyrate and sarcopenia: from biological plausibility to clinical evidence

F. Landi, R. Calvani, A. Picca, et al.

Curr Opin Clin Nutr Metab Care. 2019;22(1):37-43

The aim of this review is to discuss recent literature about beta-hydroxy-beta-methylbutyrate (HMB) metabolism, its pharmacokinetics compared with the metabolite leucine, effectiveness of HMB to improve outcomes in older adults, and novel approaches for HMB use.

Age-related changes in skeletal muscle: changes to life-style as a therapy

R. McCormick and A. Vasilaki

Biogerontology. 2018;19(6):519-536

As we age, there is an age-related loss in skeletal muscle mass and strength, known as sarcopenia. Sarcopenia results in a decrease in mobility and independence, as well as an increase in the risk of other morbidities and mortality. Sarcopenia is therefore a major socio-economical problem.

Serum Myostatin Levels Are Higher in Fitter, More Active, and Non-Frail Long-Term Nursing Home Residents and Increase after a Physical Exercise Intervention

H. Arrieta, G. Hervás, C. Rezola-Pardo, et al.

Gerontology. 2018 Nov 21:1-11. doi: 10.1159/000494137. [Epub ahead of print]

The aim is to determine the association of serum myostatin concentration with body composition, physical fitness, physical activity level, and frailty in long-term nursing home residents. We also aimed to ascertain the effect of an exercise program on myostatin levels.

Impact of medication on protein and amino acid metabolism in the elderly: the sulfur amino acid and paracetamol case

C. Mast, D. Dardevet, I. Papet

Nutr Res Rev. 2018;31(2):179-192

The present review provides the rationale for the potential pro-sarcopenic effect of paracetamol (acetaminophen; APAP) then recent results concerning the effect of chronic APAP treatment on muscle mass and metabolism are discussed.

Understanding functional and social risk characteristics of frail older adults: a cross-sectional survey study

D.R. Lee, E.C. Santo, J.C. Lo, et al.

BMC Fam Pract. 2018;19(1):170

Frailty is a condition of increasing importance, given the aging adult population. With an anticipated shortage of geriatricians, primary care physicians will increasingly need to manage care for frail adults with complex functional risks and social-economic circumstances.
