Humoral and cellular immune responses to Pfizer-BioNTech BNT162b2 SARS-CoV-2 vaccine in adolescents with liver transplantation: Single center experience.

Background: Immune responses to vaccines against severe acute respiratory syndrome (SARS)-coronavirus (CoV)-2 are variable. In the absence of disease, youngsters are expected to better react to vaccines than adults. Nevertheless, chronic immunosuppression in transplant recipients may impair their capability to generate protection.

An Intensive Lifestyle Intervention Is an Effective Treatment of Morbid Obesity: The TRAMOMTANA Study-A Two-Year Randomized Controlled Clinical Trial.

Bariatric surgery is currently the most effective therapy to induce weight loss in morbidly obese patients. Objective. This controlled, clinical trial with a two-year intervention was aimed at comparing the efficacy of two nonsurgical approaches versus bariatric surgery, on body weight changes and metabolic parameters in morbidly obese patients.

One year weight loss in the TRAMOMTANA study. A randomized controlled trial.

Background: Morbid obesity is a major health problem and bariatric surgery is currently the most effective therapy available to induce weight loss in these patients. This report describes 1-year changes in weight and metabolic parameters, in a trial designed to examine the effects of a nonsurgical approach, Intensive Life style Intervention (ILI) on the therapy of morbid obesity.

Methods: The primary outcome was change in body weight.

[TRAMOMTANA (Multidisciplinary treatment of morbid obesity: medication, behavioral therapy, nutritional support, and physical activity). From question to reality in an investigator-initiated clinical trial (II)].

Implementation of an intensive, multidisciplinary weight loss program in patients with morbid obesity is reported. This program is based on behavioral changes, lifestyle intervention, medication, and group therapy sessions. Our objective is to show that the results achieved with this two-year weight loss program will be at least similar to those achieved with bariatric surgery in patients with morbid obesity.

Evidence-based clinical practice requires integration of individual professional experience with the best objective data to make the best therapeutic decision. The best degree of scientific evidence derives from controlled, randomized clinical trials and post-marketing drug surveillance studies and meta-analyses. During our clinical activities, we often search unsuccessfully for a clinical trial which answers our scientific questions.
