The Effects of Bariatric Surgery on Kidney Oxygenation in Obese Adults With Type 2 Diabetes and Hyperfiltration
In this study the investigators will examine the effects of VAT reduction by bariatric surgery on kidney hypoxia and compare kidney oxygenation before- and after surgery in both sexes using BOLD-MRI and measures of kidney hemodynamic function. Furthermore, the investigators will assess whether kidney oxygenation is reduced in obese T2D …
Impact of Bariatric Surgery and Liraglutide on Cognitive-Behavioral Markers of Long-Term Weight Loss in Obesity
The present research project aims to study the effects of bariatric surgery and liraglutide administration (in patients already selected for one of these procedures) on two cognitive-behavioral processes partially supported by distinct brain networks: automatic approach tendencies (underpinned by the cue-reactivity network) and behavioral inhibition (underpinned by the cue-regulation network). …
Changes in the Lipidomic, Immunological and miRNA Profile in Patients Undergoing a Dietary Program or Bariatric Surgery
Obesity is a chronic disease characterized phenotypically by an increase in body weight (BMI>30 kg/m2) and by a series of associated pathologies, such as hypertension, diabetes, hepatic steatosis. The association of these pathologies compromises the patient's survival and quality of life. The multifactorial origin of obesity makes its etiopathology difficult …
Direct Measurement of Ingestive Behaviour in Relation to Sex Differences and Gastrointestinal Hormone Levels in Patients After Metabolic and Bariatric Surgery
Bariatric surgery (BS), especially procedures like Sleeve Gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB), is the most effective treatment for obesity. Yet, the exact mechanisms governing its effect are somewhat elusive, with current research mainly focusing on post-operative food intake outcomes based on self-reported data, which might not fully capture …
Evaluation of the Care Provided to Patients Who Underwent Bariatric Surgery and Were Lost to Follow-up 5 Years After Surgery
In 2025, bariatric surgery combined with nutritional and psychological support is one of the most effective treatments for patients with morbid obesity. (2)(3) However, it causes various deficiencies, such as vitamin and iron deficiencies, which justify lifelong personalised vitamin supplementation and, consequently, lifelong medical supervision. The latest recommendations from the …
The Proportion of Dietary Protein Digested as Measured by the Dual-isotope Method.
The retrospective cohort study will compare the prevalence of sarcopenia and associated factors between older patients who have undergone bariatric surgery and older patients with obesity without previous bariatric surgery.
9-Step Magnetic Bariatric Revisional Surgery
RYGB represents one of the best alternatives for weight loss in obese patients achieving a weight loss of up to 60% and a resolution of comorbidities of 70%. Revision surgery contemplates multiple techniques including the conversion from one surgical technique to another, structural changes to the primary technique, among others. …
Mucosal Impedance Sleeve Gastrectomy
Obesity is a growing epidemic and bariatric surgery has been shown to be the most effective and efficient mean of achieving significant and sustainable weight loss in morbidly obese individuals. Studies have demonstrated that after LSG, between 5 and 30% of patients suffered from GERD, with a small subset of …
CV Imaging of Metabolic Interventions
Cardiovascular disease is the leading cause of death worldwide. It is becoming clearer that heart failure (HF) is closely associated with body's metabolism. Even before the heart becomes weaker, it responds to the stresses by changing the fuels it burns, which results in a reduction in the heart's metabolic efficiency …
