Bioelectrical impedance analysis in the assessment of sarcopenia

M.C. Gonzalez, T.G. Barbosa-Silva, S.B. Heymsfield

Curr Opin Clin Nutr Metab Care. 2018;21(5):366-374

As bioelectrical impedance analysis(BIA) equations and cut-off values are population and device-specific, results should be interpreted with caution when data from different devices are applied in equations or using cut-off values from a different population.

Reduced plasma concentration of branched-chain amino acids in sarcopenic older subjects: a cross-sectional study

I. Ottestad, S.M. Ulven, L.K.L. Øyri, et al.

Br J Nutr. 2018;120(4):445-453

Branched-chain amino acids (BCAA) are essential amino acids that are necessary for muscle mass maintenance. Little is known about the plasma concentrations of BCAA and the protein intake in relation to sarcopenia. We aimed to compare the non-fasting plasma concentrations of the BCAA and the dietary protein intake between sarcopenic and non-sarcopenic older adults.

Longitudinal Associations Between Walking Speed and Amount of Self-reported Time Spent Walking Over a 9-Year Period in Older Women and Men

J.R. Best, T. Liu-Ambrose, A.L. Metti, et al.

J Gerontol A Biol Sci Med Sci. 2018;73(9):1265-1271

In this longitudinal study, we hypothesized that early mobility limitations would contribute to later decreases in physical activity to a larger degree than the reciprocal association of early decreases in physical activity to later mobility limitations.

Identification of frailty by the use of the SEGAm scale (part A) in geriatrical consultation

A.A. Zulfiqar

Geriatr Psychol Neuropsychiatr Vieil. 2018;16(3):269-277

A prospective, observational study was performed in subjects aged over 75 years, coming from the first neuro-geriatric consultation, from July 3, 2017 to August 18, 2017, included in the CHU Rouen, and benefiting from frailty screening through the use of the grid SEGAm (part A); this correlated with the subjective opinion of the nurse.

Comparing Mini Sarcopenia Risk Assessment With SARC-F for Screening Sarcopenia in Community-Dwelling Older Adults

M. Yang, X. Hu, L. Xie, et al.

J Am Med Dir Assoc. 2018 Jun 13. pii: S1525-8610(18)30229-9. doi: 10.1016/j.jamda.2018.04.012. [Epub ahead of print]

The Mini Sarcopenia Risk Assessment (MSRA), a new sarcopenia screening tool, has 2 versions: MSRA-7 (full version, 7 items) and MSRA-5 (short version, 5 items).

We aimed to compare the diagnostic values of MSRA-7 and MSRA-5 to SARC-F for screening sarcopenia.

SARC-F for sarcopenia screening in community-dwelling older adults: Are 3 items enough?

M. Yang, X. Hu, L. Xie, et al.

Medicine (Baltimore). 2018;97(30):e11726

A 3-item SARC-F (termed SARC-F-3 in our study) was recently suggested as a screening tool for sarcopenia.

The aim of this study was to compare the diagnostic value of SARC-F-3 to SARC-F in community-dwelling older people.
