MFI and FFMV combined provides a more complete, muscle-specific description linked to function enabling objective sarcopenia detection. Relative power decreased i) above 40 years by the loss in absolute power (specific power only) and the increase in body mass, and ii) above ̴ 70 years by the loss in absolute power (both specific power and leg lean mass).

SP also had an anti-diabetic effect in VAT and skeletal muscle because it upregulated glucose transporter type 4 (GLUT4) and uncoupling protein 3 (UCP3) expression. Furthermore, SP reduced ubiquitin proteasome and promoted myoblast determination protein 1 (MyoD)/myogenic factor 4 (myogenin) expression, implying that it may have potential for the treatment of obesity-induced hyperglycemia and obesity-associated sarcopenia.

Taken together, these results suggest that the intrinsic trophic differences between EOMs-derived myogenic progenitors and their counterparts from other muscles could explain why those cells show higher proliferative and fusion rates, as well as better regenerative properties. SDOC cut-points for grip strength standardized to weight provided consistent indication of poor walking speed performance post hip fracture.

When an accurate assessment of muscle mass (rather than lean mass) is used, reduced muscle mass is highly associated with important outcomes and the negative effects of adiposity are minimal, suggesting that obesity has little relevance for the understanding of important adverse health outcomes of sarcopenia in older men. Nondairy animal protein intake (within a Western dietary pattern and alone) was positively associated with D3Cr muscle mass in older men.

(Pubmed Central) - Feb 10, 2021 The C2C12 cell line is used as myoblasts or is differentiated in myotubes, sarcopenia is induced by dexamethasone (DEX)...During the early phase of myotube formation, the mixture preserves the number of myogenin-positive cells, whereas it completely prevents the DEX-dependent damage in a later phase of myotube differentiation (7 days), as evaluated by cell diameter and percentage of multinucleated cells. R(+)LA in association with HMB is suggested for sarcopenia therapy.

Additionally, patients with sarcopenia had a longer length of stay in the ICU, and univariate and multivariate analyses confirmed that the ICU length of stay was significantly related to sarcopenia (adjusted odds ratio=1.187; 95% confidence interval, 1.019-1.382; p=0.028). The length of stay in the ICU was significantly associated with sarcopenia in hemiplegic stroke patients.

Such information may help to improve anti-aging strategies by countering age-specific muscle function deficiencies and may improve mid-life adults' ability to transition better functionally into old age. Sarcopenia is highly prevalent in individuals with CVD, dementia, diabetes mellitus and respiratory disease.

Although not yet completely elucidated, numerous molecular processes involved in mitochondrial biogenesis and turnover are affected with age. The contrasting and often opposite consequences of exercise and age suggest that exercise can serve as non-pharmacological "mitochondrial medicine" for aging muscle to ameliorate mitochondrial content and function, via pathways that implicate organelle protein quality control mechanisms.
- |||||||||| Journal: Handgrip Strength Is an Independent Predictor of Cardiovascular Outcomes in Diabetes Mellitus. (Pubmed Central) - Feb 9, 2021
Multivariate Cox hazard analysis identified the cardio-ankle vascular index (CAVI) and handgrip strength as independent predictors of MACE (hazard ratio [HR] = 1.18, P = 0.039; and HR = 0.70, P = 0.016, respectively).Handgrip strength is an indicator of sarcopenia in diabetic patients, and together with CAVI it was independently associated with the incidence of MACE. This suggests that the handgrip strength test might be useful in the management of patients with DM at high risk of cardiovascular outcomes.

However, the treatment of all these conditions still remain debated and only a profound knowledge of the specific mechanisms and patterns of disease progression will allow to use the appropriate therapy in a given clinical setting. For all these reasons we briefly review current knowledge on frailty, sarcopenia and cachexia in HF patients with the attempt to define clinically significant degrees of multiorgan dysfunction, specific "red alert" thresholds in clinical practice and therapeutic approach.
