A prática docente em uma instituição de ensino inserida no serviço público de saúde
Objective: the research aimed to analyze the perception of teachers about the experience of active methodologies based on their experience at the School of Health Sciences. Method: this is an exploratory and qualitative study, with semi-structured interviews carried out with professors of the Undergraduate Nursing and Medicine Courses. The data were analyzed using Iramuteq and MAXQDA software. Results: in the 21 in-depth interviews, teachers pointed out that active methodologies are a strength for student learning. As weaknesses, rigidity and erosion of the methodological stages of teaching. Final considerations: the teaching and learning process in active methodologies has the teacher as a facilitator and they proved to be adapted to the methodological proposal.

Hypoabsorption in Bariatric Surgery: Is the Benefit Worth the Risk?
Metabolic and bariatric surgery has been well described in the existing literature to be an effective and safe modality for weight loss in patients with obesity. Recently, hypoabsorptive procedures such as one-anastomosis gastric bypass (OAGB), biliopancreatic diversion with duodenal switch (BPD-DS), and single-anastomosis duodenoileostomy with sleeve (SADI-S) have gained traction, particularly among patients with severe obesity. These procedures combine restrictive and hypoabsorptive mechanisms, resulting in significant and sustainable weight loss, especially in those with severe obesity and associated comorbidities. However, the risk of malnutrition and nutritional deficiency following these procedures has been a deterrent for surgeons in their adoption. This review evaluates the existing literature on the safety, efficacy, and long-term outcomes of OAGB, BPD-DS, and SADI-S. While these hypoabsorptive procedures represent highly effective options for treating obesity, the associated nutritional complications necessitate the need for long-term follow-up and supplementation and highlight the need for careful patient selection.

Novel Surgical Interventions for the Treatment of Obesity
Metabolic and bariatric surgery is widely recognized as the most effective and durable treatment for the disease of obesity and its associated comorbidities. In recent years, the field has seen significant advancements, introducing numerous innovative surgical options. This review aims to comprehensively examine these emerging surgical techniques, which have recently received endorsement from the American Society for Metabolic and Bariatric Surgery (ASMBS). Additionally, we will explore new technologies and methodologies supported by the latest scientific evidence. Our analysis will include a critical evaluation of the efficacy, safety, and long-term outcomes of these novel approaches, providing a detailed update on the current state of metabolic and bariatric surgery, highlighting key developments and their potential implications for clinical practice.
