Gut microbiota is essential for the development of obesity and related comorbidities. However, studies describing the association between specific bacteria and obesity or weight loss reported discordant results. The present observational study, conducted within the frame of the PREDIMED-Plus clinical trial, aims to assess the association between fecal microbiota, body composition and weight loss, in response to a 12-month lifestyle intervention in a subsample of 372 individuals (age 55-75) with overweight/obesity and metabolic syndrome. Participants were stratified by tertiles of baseline body mass index (BMI) and changes in body weight after 12-month intervention. General assessments, anthropometry and biochemical measurements, and stool samples were collected. 16S amplicon sequencing was performed on bacterial DNA extracted from stool samples and microbiota analyzed. Differential abundance analysis showed an enrichment of , UCG-001 and , associated with a higher weight loss after 12-month of follow-up, whereas in the cross-sectional analysis, and were enriched in the lowest tertile of baseline BMI. Our findings suggest that fecal microbiota plays an important role in the control of body weight, supporting specific genera as potential target in personalized nutrition for obesity management. A more in-depth taxonomic identification method and the need of metabolic information encourages to further investigation.

Background: Preoperative treatment with glucagon-like peptide-1 receptor agonists (GLP-1 RAs) before bariatric surgery has not been studied. Therefore, we investigated the impact of neoadjuvant treatment with GLP-1 RAs on weight loss and postoperative outcomes in patients who underwent sleeve gastrectomy for severe obesity.
Method: A retrospective single-center study was conducted between January 2022 and December 2023.

Background: We retrospectively evaluated the efficacy of using additional obesity management medications (OMMs) within the first year after undergoing laparoscopic sleeve gastrectomy (LSG).
Methods: We retrospectively analyzed 246 patients who underwent primary LSG in our institution and were followed up for at least 12 months. We collected body weights preoperatively and at three, six, 12, and 24 months postoperatively, along with body composition and laboratory results preoperatively and at 12 months.

Purpose: Screening and diagnosing ISUP ≥ 2 prostate cancer is challenging. This study aimed to determine whether canine detection could be beneficial addition to the ISUP ≥ 2 prostate cancer diagnostic protocol by creating a decision-making algorithm for men with suspected prostate cancer.
Methods: We conducted a prospective study at two urology institutions and a French veterinary school, including men with a suspicion of prostate cancer from November to April 2023, which were divided into two groups according to their prostate biopsy results.

Existing evaluations of the National Health Service Diabetes Prevention Programme (NHS DPP) in England have demonstrated associated reductions in body weight, hemoglobin A1c and incident type 2 diabetes (T2D). In this study, we examined associations between completion of the NHS DPP and incidence of T2D and 30 other long-term conditions (LTCs), including LTCs considered linked to the program's interventional goals of body weight reduction, increased physical activity and improved diet quality (LTC-L) and LTCs considered to be possibly linked to those goals (LTC-PL). We found that completers of the NHS DPP had lower incidences of T2D, LTC-L and LTC-PL compared to non-attenders.

Background: The relationship between intraoperative end-tidal CO (etCO) levels and postoperative outcomes remains unclear. We conducted a post hoc analysis of two randomised trials in adults undergoing major surgery under general anaesthesia.
Methods: We re-analysed individual participant data comparing high or low positive end-expiratory pressure with low tidal volume intraoperative ventilation using a merged database derived from two randomised trials in non-obese (PROVHILO: ISRCTN70332574) and obese (PROBESE: NCT02148692) patients.
