Nutrition Therapy

This is a multicenter, randomized controlled, phase III clinical trial. The purpose of this study is to evaluate the efficacy of standard nutrition treatment versus conventional nutrition treatment in local advanced nasopharyngeal carcinoma patients.

The study is designed to investigate the effect of a multicomponent prehabilitation pathway on early and long-term outcomes in elderly patients with frailty recovering from surgery for digestive cancer.

The goal of this clinical trial is to examine the effect of 3 versus 6 daily meals of isocaloric diets on glycemic control and variability in individuals with type 1 diabetes. Participants will be randomized in a crossover clinical trial and will receive two different types of isocaloric diet interventions, in 3 meals/day (calorie distribution: 30% at breakfast, 40% at lunch and 30% at dinner) or 6 meals/day (calorie distribution: 20% at breakfast, 10% at morning snack, 30% at lunch, 10% at afternoon snack, 25% at dinner and 5% at evening snack), for three weeks, with a 4-week washout period between diets.
