    Background: : Cholecystectomy due to gallstones is one of the most frequent surgeries worldwide. Observational studies suggest that cholecystectomy may be a risk factor for metabolic dysfunction associated with steatotic liver disease (MASLD). However, gallstone disease and MASLD share common risk factors, which could make cholecystectomy a confounder.Aim: To assess the relationship among cholecystectomy, gallstones, and MASLD in a longitudinal cohort study from a population at high risk of gallbladder diseases.Methods: A longitudinal retrospective cohort study compared consecutive patients undergoing cholecystectomy with a control group composed of patients with their gallbladder intact. All participants had normal liver imaging and biochemistry at baseline. Participants with incomplete clinical records or significant alcohol consumption were excluded. The primary outcome was the development of MASLD after a follow-up of at least 3 years. Cox regression models were used to conduct multivariable analyses.Results: We included 427 participants 132 in the cholecystectomy group and 295 controls. The mean age was 47.2 years, with 71.7% being female, and 43.6% having gallstone disease. The median follow-up was 9.7 years.In the Cox multivariate analysis, male gender (aHR: 1.56 [1.09-2.24]), gallstone disease (aHR: 2.18 [1.42-3.36]), prediabetes (aHR: 1.56 [1.06-2.3]), diabetes (aHR: 2.39 [1.38-4.13]), and overweight/obesity (aHR: 5.7 [3.19-10.21]) were independent risk factors for MASLD. After adjustment, cholecystectomy was not associated with MASLD incidence (aHR: 0.68 [0.44-1.03]). Sensitivity analyses supported these findings.Conclusion: Cholecystectomy was not found to significantly influence the incidence of MASLD after adjusting formetabolic risk factors. The risk of developing MASLD is likely driven by metabolic factors and previous gallstone disease.

    The new 2015 criteria for neuromyelitis optica spectrum disorders (NMOSD) have been recently incorporated in the study of different international cohorts. Aim. To describe clinical-radiological characteristics and prognostic factors in patients with NMOSD according to the 2015 criteria. Patients and methods. Retrospective analysis of 36 patients diagnosed with NMOSD according to serologic AQP4 status (positive, negative, unknown and negative + unknown). Clinical and radiological characteristics were compared and possible disability prognostic factors were evaluated. Results. AQP4 were positive in 7 patients, negative in 12 and unknown in 17. Age of presentation was 36.6 ± 16 years, with higher female proportion (4:1). Mean disease duration was 7.4 ± 7.6 years. Most frequent presenting symptoms were acute myelitis (61%), optic neuritis (33%) and area postrema syndrome (11%). Most frequent MRI lesion was longitudinally extensive transverse myelitis (75%). All patients received acute treatment during attacks, and preventive treatment was used in 81% (azathioprine and rituximab mostly prescribed). Median EDSS was 2.0 at the end of follow-up. No differences were observed in any of the variables comparing serologic status. Age of first attack was prognostic, with direct correlation with EDSS. First attack in < 30 years was protective, meanwhile > 50 years old patients had increased risk of disability. Conclusions. The 2015 criteria allow the description and classification of NMOSD patients within different cohorts. Age of first attack seems to be a prognostic factor for developing disability.
