- Comparative Performance of Preoperative Diabetes-Remission Scores Following Metabolic Bariatric Surgery: A Retrospective Cohort Study in a Malaysian Population. [Journal Article]
- CONCLUSIONS: In a predominantly Malay, sleeve-predominant cohort, all three scores predicted remission. Adding diabetes duration alone (DiaRem2) did not improve on the original DiaRem, whereas Ad-DiaRem, which also incorporates treatment burden and re-weighted penalties, discriminated best. Because the medication components were reconstructed retrospectively, and because the study was not powered to detect modest differences between scores, these comparisons require confirmation.

- Factors Associated with Postoperative Hemorrhage in Primary Metabolic Bariatric Surgery: Nationwide Analysis of Patient Characteristics, Surgical and Stapling Techniques. [Journal Article]
- CONCLUSIONS: Despite limitations inherent in its retrospective, questionnaire-based design, the findings indicate that patient-related factors are associated with postoperative hemorrhage risk in MBS.

- Weight Loss Measurements Under the Microscope: How Type and Baseline Definition Shape Clinical Response After Metabolic-Bariatric Surgery - A 2-Year Follow-up Analysis of 17,568 Patients. [Journal Article]
- CONCLUSIONS: The choice of weight-loss metric and baseline definition substantially influences the classification of postoperative weight-loss response and the apparent association between preoperative characteristics and surgical outcomes. %EWL and %TWL are not interchangeable measures and can produce opposing interpretations of the association between baseline BMI and postoperative response. Consistent with the 2024 IFSO consensus, weight-loss assessment after MBS should use a baseline established before initiation of preoperative weight reduction where appropriate, particularly when evaluating the overall treatment trajectory. %TWL provides a more readily comparable metric for standardized reporting, whereas %EWL may remain useful for comparison with historical literature. Because clinical response after MBS is multidimensional, weight-loss thresholds should not be interpreted as synonymous with clinical treatment failure.

- The Reported Prevalence of Micronutrient Deficiency after Metabolic Bariatric Surgery and Adherence to British Obesity and Metabolic Specialist Society Nutritional Guidelines: A Multicentre Retrospective Cohort Study. [Journal Article]
- CONCLUSIONS: Among patients with available biochemical testing, micronutrient deficiencies were frequently observed during the first year after MBS. The observed frequency of low zinc and selenium amongst tested patients warrants further prospective investigation to explore clinical implications and to evaluate the earlier and more systematic monitoring of trace minerals after MBS. Inconsistencies in micronutrient blood monitoring and substantial missing postoperative data may suggest that the BOMSS nutritional monitoring guidelines are not being fully implemented in clinical practice across England, limiting the availability of real-world postoperative micronutrient data.

- Development and Validation of a Machine Learning Model for Predicting One-year Anemia After Bariatric Surgery: A Multicenter Study. [Journal Article]
- CONCLUSIONS: A seven-variable preoperative model showed good discrimination for one-year anemia status after bariatric surgery and may support individualized postoperative monitoring and nutritional care.

- Association Between Preoperative Anemia and Incident Chronic Kidney Disease after Metabolic and Bariatric Surgery: a Propensity Score-matched Cohort Study. [Journal Article]
- CONCLUSIONS: Preoperative anemia was associated with increased 5-year renal risk after MBS. Postoperative anemia was more frequent among these patients, but this temporal association should not be interpreted as evidence of mediation or causality. Preoperative hemoglobin may help identify patients requiring closer renal surveillance, although further validation is needed.

- Trends in Metabolic and Bariatric Surgery Procedure Volume Recorded in MBSAQIP, 2015-2024. [Journal Article]
- CONCLUSIONS: Annual MBSAQIP procedure volume increased through 2022 among adults and adolescents but declined in 2023-2024 only among adults. This emerging pattern warrants continued surveillance to determine whether it persists and to understand its implications for surgical access, treatment selection, and the delivery of obesity care.

- Long-Term Outcomes and Predictors of Recurrent Weight Gain After Sleeve Gastrectomy, Roux-En-Y Gastric Bypass, and One Anastomosis Gastric Bypass: Turkish Metabolic and Bariatric Surgery Follow-up Study (TMBS Study). [Journal Article]
- CONCLUSIONS: In this Turkish multicenter retrospective cohort with long-term follow-up, OAGB was associated with greater current %TWL and lower RWG compared with SG, while RYGB showed intermediate weight outcomes. Given the small OAGB subgroup, confirmation in larger prospective studies is warranted.

- Ultra-processed Food Consumption After Metabolic and Bariatric Surgery: Implications for Recurrent Weight Gain, Dietary Quality, and Nutritional Outcomes - A Narrative Review. [Review]
- Ultra-processed food (UPF) intake is increasingly linked to poor dietary quality, but its course after metabolic and bariatric surgery (MBS) is unclear. This narrative review synthesized 12 observational reports (7 independent datasets) on postoperative UPF consumption and its associations with weight outcomes, dietary quality, and nutritional status. UPF intake fell early after surgery but rebou…

- Metabolic and Bariatric Surgery and Bone Mineral Density: A 9-Year Prospective Study. [Journal Article]
- CONCLUSIONS: Nearly a decade after metabolic and bariatric surgery, bone mineral density may be significantly decreased at the femoral neck. Further prospective studies are warranted to clarify the mechanical, hormonal, and metabolic mechanisms underlying long-term skeletal health following metabolic and bariatric surgery.

- Weight-Loss and Metabolic Outcomes of a Swallowable Fluid-Filled versus an Adjustable Intragastric Balloon in Adults with Overweight or Obesity: A Retrospective Single-Center Study with 12-Month Weight Outcomes. [Journal Article]
- CONCLUSIONS: Both IGBs produced meaningful weight loss and metabolic improvement, but comparison between them is strongly time-dependent: the swallowable balloon's short-term advantage per month of dwell was not maintained at 12 months. Incomplete adjustable-group follow-up means the device comparison should be read as an upper bound. Metabolic improvement was similar between devices and not proportional to weight loss.

- Treatment With a GLP-1 Receptor Agonist Versus Reduction of the Gastrojejunal Anastomosis Diameter Using Endoscopic Argon Plasma Coagulation for Recurrent Weight Gain After Roux-en-Y Gastric Bypass. [Journal Article]
- CONCLUSIONS: Overall, patients treated with liraglutide 3.0 mg maintained a %TWL of approximately 15% between 12 and 24 months of follow-up, whereas patients treated with APC achieved a mean %TWL below 10% during the same period.

- Patient Perceptions and Barriers to Metabolic Bariatric Surgery Among Adults with Obesity in the West Bank, Palestine: A Cross-Sectional Study. [Journal Article]
- CONCLUSIONS: Despite adequate knowledge and moderately positive attitudes, important misconceptions and barriers persisted regarding metabolic benefits, long-term outcomes, and financial/social concerns. These potentially modifiable barriers may impede MBS acceptance. Targeted education, multidisciplinary counseling, and strategies addressing financial/social barriers may improve informed decision-making and facilitate access to bariatric care in Palestine and similar settings. The predominance of female participants (72.9%) should be considered when generalizing findings to men.

- Crural Repair with or without Fundoplication During Sleeve Gastrectomy for Hiatal Hernia: Reflux Recurrence and Intrathoracic Migration at 18 Months. [Journal Article]
- CONCLUSIONS: Adding a fundoplication was associated with better symptomatic, endoscopic and anatomic outcomes, without impairing weight loss. Hernia size did not identify patients in whom crural repair alone sufficed.
