Sarcopenia is characterized by a low SLM and is a strong predictor of peripheral muscle weakness associated with reduced exercise capacity and high mortality.[35,36] Moreover, elevated IL-6, IL-8, and TNF-α levels have been associated with advanced muscle loss, malnutrition, and cachexia.[36] Although there was no apparent difference in body composition between our groups, SLM was lower in elderly patients (SLM: 20.06 vs 15.84 kg/m2, P = .04), suggesting a degree of sarcopenia in group B. This evidence concerns the gene TNF and malnutrition.
