Obesity is both a major risk factor for diabetes and a serious comorbidity of the condition. The twin epidemics of obesity and diabetes have spread globally over the past few decades. Treatment of obesity in patients with diabetes provides a host of clinical benefits that encompass virtually all body systems. Despite this, multiple lines of evidence suggest that the efficacy of most therapies for weight loss is significantly reduced among patients with diabetes. With this background, we summarize the evidence of a differential effect of lifestyle, pharmacological, and surgical treatments for obesity in patients with existing diabetes, and explore the potential mechanisms involved in this phenomenon...

There is an urgent need to measure the motivation to taste a sweet fluid in order to determine the influence of sweet tastes on the potential choices and consumption of beverages in patients with obesity. Current methods utilize either survey instruments or arbitrary operant tasks. The sipometer enables the participant to utilize an actual ingestive behavioral response to measure motivation during access to beverages on either ad libitum (AL) or progressive time ratio (PR) schedules. We determined the sipometer's responsiveness and reliability as a test of change in motivation for sweet tastes after bariatric surgery...

Background : Psychiatric symptoms are highly prevalent in patients with severe obesity, often representing pivotal factors in the development and progression of this condition. This study examines the association between negative emotional dysregulation (NED) and weight loss following bariatric surgery. Methods : Ninety-nine patients were consecutively enrolled at the Obesity Center of the Pisa University Hospital between March 2019 and February 2021, during a routine psychiatric evaluation before bariatric surgery...

Background: Bariatric surgery (BS) is effective for achieving significant weight loss. However, weight regain (WR) is an emerging problem. Objective: To assess the prognostic value of morning serum cortisol, a 1 mg dexamethasone suppression test (DST), 24 h urinary free cortisol (UFC) and late-night salivary cortisol (LNSC) in a cohort of patients with severe obesity (pwSO) undergoing BS in terms of weight loss and WR. Methods: Patients scheduled for BS underwent the following procedures at baseline, 12 months and 24 months after BS: medical history, anthropometric data, blood analysis and cortisol tests...

Background : The prevalence of obesity is already a worldwide health concern. The development of straightforward guidelines regarding the whole available armamentarium (i.e., medical, endoscopic, and surgical interventions in conjunction with a guidance program) is paramount to offering the best multimodal approach to patients with obesity. Methods : The International Federation for Surgery of Obesity and Metabolic Disorders-European Chapter (IFSO-EC) identified a panel of experts to develop the present guidelines...

BACKGROUND: The field of metabolic and bariatric surgery (MBS) is currently an expanding surgical field with constant refinements in techniques, outcomes, indications, and objectives. MBS has been effectively applied across diverse patient demographics, including varying ages, genders, body mass indexes, and comorbidity statuses. METHODS: We performed a comprehensive literature review of published retrospective cohort studies, meta-analyses, systematic reviews, and literature reviews from inception to 2024, reporting outcomes of MBS using databases such as PubMed, ScienceDirect, and Springer Link...

PURPOSE: Metabolic bariatric surgery (MBS) became integral to managing severe obesity. Understanding surgical risks associated with MBS is crucial. Different scores, such as the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP), aid in patient selection and outcome prediction. This study aims to evaluate machine learning (ML) models performance in predicting 30-day post-operative complications and compare them with the MBSAQIP risk score. MATERIALS AND METHODS: We retrospectively evaluated 424 consecutive patients (2006-2020) who underwent MBS, analyzing 30-day surgical complications according to Clavien-Dindo Classification...

BACKGROUND: Despite excellent surgical outcomes, a minority of qualified patients undergo weight loss surgery. Endoscopic Sleeve Gastroplasty (ESG), an incisionless procedure, has proven to be effective in achieving weight loss and comorbidity improvement. We aim to compare outcomes of ESG to those of Laparoscopic Sleeve Gastrectomy (LSG). METHOD: A retrospective review of a prospective database of patients who underwent ESG and LSG at NorthShore University HealthSystem from 2016 to 2023 was completed...

Background: The COVID-19 pandemic and subsequent lockdowns led to substantial changes in health-related behaviors and deferred elective surgeries. This study aimed to evaluate the impact of the COVID-19 lockdown on weight loss trajectories (WLT) and perioperative outcomes in primary bariatric surgery at a single tertiary referral center. Methods: Patients who underwent primary bariatric surgery immediately prior to the enforced lockdown (During-Lockdown Group, DLG) were compared with historical controls who underwent surgery before the lockdown (Before-Lockdown Group, BLG)...

OBJECTIVE: To analyze learning curves and appropriate experience on the features of mini-bypass surgery in 341 obese patients. MATERIAL AND METHODS: A total of 341 laparoscopic mini-gastric bypass surgeries performed by one surgeon were studied. The median age of patients was 40.5 [34; 48.3] years. There were 284 (83.2%) women and 57 (16.8%) men. The median BMI was 45 [40;52] kg/m2 . RESULTS: The period of MGB development consisted of 138 interventions...

OBJECTIVE: in recent years, bariatric surgery has gained popularity as a treatment for obesity worldwide. While patients do experience weight loss after surgery, it is important to be aware that serious nutritional deficiencies may also occur. This study was conducted to evaluate the nutritional status of morbidly obese patients in the first six months after sleeve gastrectomy. METHODS: the study was planned as a retrospective study. The data of 76 patients aged 19-64 years who had undergone bariatric surgery and were followed by a dietitian for at least 6 months were included in the study...

BACKGROUND: The uptake of obesity treatments remains disproportionally low in people living with the disease, even with the advent and availability of GLP-1 agonists in recent years. Efforts to understand this discrepancy have centred on literature syntheses and Healthcare Professionals' (HCPs) perspectives on the barriers to obesity treatment. This study focuses on patient perspectives on the risks of obesity treatment. METHOD: This qualitative study consisted of online focus groups with 30 adults with obesity from Europe and North America...

BACKGROUND: Obesity is a significant risk factor for metabolic-associated steatotic liver disease (MASLD). The association between Helicobacter pylori (HP) infection and liver fibrosis has not been fully elucidated in patients with obesity and MASLD. METHODS: This observational retrospective study included clinical and biochemical parameters of patients with obesity undergoing bariatric surgery. HP infection was confirmed by gastric endoscopy, and liver biopsies were performed during surgery...

Patients with hereditary polyposis syndromes (HPS) are among the highest risk of multiple types of cancer. This risk is further magnified by comorbid obesity; however, HPS present unique risks for bariatric surgery. The advent of endoscopic bariatric and metabolic therapies along with advancements in the realm of antiobesity medications provides potential weight loss alternatives in this vulnerable population. We present 2 cases of patients with obesity and HPS successfully treated with intragastric balloons in combination with antiobesity medications...
