The human gut hosts more than 100 trillion microorganisms, encompassing thousands of species. In adults, Bacteroidetes and Firmicutes are the most prevalent phyla. Experimental data in animal and observational studies in obese patients suggest that obesity is associated with substantial changes in the composition and metabolic function of the gut microbiota. The initial findings linked obesity with the decreased relative proportion of Bacteroidetes to Firmicutes. There are some authors who suggest that probiotics and prebiotics can modulate obesity-host metabolism in obesity and obesity-related disorders., (Copyright © 2012 S. Karger AG, Basel.)

Malnutrition and sarcopenia are frequent in the hospitalized and institutionalized elderly. They have negative consequences on morbidity, mortality, function and quality of life. Enteral and parenteral nutrition are valid options in the malnourished elderly, both in the hospital and at home. Elderly patients share most indications and complications with adult patients, even though more focus needs to be put on function and quality of life than on mortality. In these guidelines we discuss the indications and special considerations of enteral and parenteral nutrition in geriatric patients as well as guidelines for clinical nutrition in three common pathologies in the elderly: decubital ulcers, dysphagia and dementia.
