Obesity is an important risk factor and a potential treatment target for hepatic steatosis. The maladaptation of hepatic mitochondrial flexibility plays a key role in the hepatic steatosis. Herein, we found that hepatocyte-like cells derived from human adipose stem cell of obese patients exhibited the characteristics of hepatic steatosis and accompanied with lower expression of the subunits of mitochondrial complex I and lower oxidative phosphorylation levels. The GSK3 inhibitor CHIR-99021 promoted the expression of NDUFB8, NDUFB9, the subunits of mitochondrial complex I, the basal oxygen consumption rate, and the fatty acid oxidation of the hepatocytes of obese patients by upregulating the expression of the transcription factor PGC-1α, TFAM, and NRF1 involved in mitochondrial biogenesis. Moreover, CHIR-99021 decreased the lipid droplets size and the triglyceride levels in hepatocytes of obese patients. The results demonstrate that GSK3 inhibition ameliorates hepatic steatosis by elevating the mitochondrial function in hepatocytes of obese patients.

Aim: Sarcopenic obesity (SO) is associated with adverse outcomes in diseased patients. This study aimed to examine the prevalence and risks associated with SO, with a focus on the impact of SO on cardiovascular risk in patients with MASLD.
Materials And Methods: In this cross-sectional study, patients with MASLD were prospectively enrolled.

The surgical risk is higher for obese patients undergoing laparoscopic left hemicolectomy. To enhance the surgical safety and efficacy for obese patients, we have innovatively integrated the advantages of various surgical approaches to modify a pancreas-guided C-shaped surgical procedure. The safety and quality were assessed through a retrospective analysis.

Purpose Of Review: Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most common chronic liver disease, characterized by hepatic steatosis with at least one cardiometabolic risk factor. Patients with MASLD are at increased risk for the occurrence of cardiovascular events. Within this review article, we aimed to provide an update on the pathophysiology of MASLD, its interplay with cardiovascular disease, and current treatment strategies.

Introduction: Obesity and its complications are associated with high morbidity/mortality and a significant healthcare cost burden in Spain. It is therefore essential to know the potential clinical and economic benefits of reducing obesity. The objective of this study is to predict the decrease in rates of onset of potential complications associated with obesity and the cost savings after a weight loss of 15% over 10 years in Spain.

Background: In this study, we aimed to investigate whether ursodeoxycholic acid (UDCA) would reduce the necessity of cholecystectomy in patients diagnosed with asymptomatic gallstones after laparoscopic sleeve gastrectomy (LSG) and in patients diagnosed with asymptomatic gallstones before LSG.
Methods: Between July 2020 and November 2022, at least 2-year follow-ups of patients who underwent LSG for obesity were retrospectively analyzed. Patients with pre-existing asymptomatic gallstones during preoperative evaluation, those with UDCA treatment (group 1), and observation group (group 2).
