The aim of this study was to assess the prevalence of skeletal muscle mass loss and its association with swallowing function in patients with dysphagia after cardiovascular surgery. ⋯ The prevalence of skeletal muscle mass loss is very high, and skeletal muscle mass loss is associated with swallowing function.

The aim of the present study was to investigate the putative effects of a low-protein diet on the three-dimensional structure of hepatocytes and determine whether this scenario could be reversed by restoring the adequate levels of protein to the diet. ⋯ Awareness of these data will add to a better morphologic understanding of malnutrition-induced hepatopathies and will help clinicians improve the diagnosis and treatment of this condition in humans and in veterinary practice.

Coffee, one of the world's most consumed beverages, has many benefits. Some studies have reported the effects of coffee on aging. The aim of this study was to investigate the locomotor activity, energy metabolism, and lipid metabolism of aged (20-mo-old) mice given coffee. ⋯ Regular and decaffeinated coffee consumption decreased hepatic total mTOR and p-mTOR levels independently of Akt and AMPK pathways in aged mice. Because decreased mTORC1 activity is known to have antiaging effects, coffee consumption during old age may retard aging. Moreover, coffee consumption by the aged population had a positive effect on behavioral energy and lipid metabolism.
