Preoperative Physical Activity Improvement with the Use of Activity Trackers in Patients Undergoing Radical Cystectomy-A Bicentric, Open-label, Randomised Controlled Trial: A Clinical Study Protocol of the PreAct Trial.

This study protocol shows the structured design of the randomised controlled phase 3 "PreAct" trial. It hypothesises the use of a fitness tracker-based prehabilitation programme to increase the physical activity of patients prior to radical cystectomy, as measured by the average number of steps per day.

Nutritional Deficiencies in Patients after Roux-en-Y Gastric Bypass and Sleeve Gastrectomy during 12-Month Follow-Up.

Introduction: Roux-en-Y gastric bypass (RYGB) and laparoscopic sleeve gastrectomy (LSG) are the two most frequently performed bariatric operations. These two types of metabolic surgery alter the anatomy and function of digestive tract producing significant weight loss in morbidly obese patients but may lead to malnutrition.

Aim: Analysis of incidence and severity of malnutrition after bariatric surgery in patients submitted to RYGB or LSG during 12 months of follow-up.
