Mechanism of TIPS to Improve Sarcopenia

Sarcopenia is particularly common in patients with chronic liver disease, especially in patients with decompensated cirrhosis, where the prevalence can be more than 50%. Sarcopenia is an important risk factor for a significant increase in mortality in cirrhotic patients, and is closely associated with a high incidence of complications such as hepatic encephalopathy, ascites, and infections . Recent studies have found that TIPS not only significantly improves clinical symptoms caused by portal hypertension, but may also have a positive effect on skeletal muscle mass and function in patients. Although the effect of TIPS in improving sarcopenia has been preliminarily confirmed, its mechanism is not yet fully understood. Therefore, there is an urgent need to explore the mechanism of action of TIPS to improve sarcopenia and provide guidance for clinical treatment options.

Changes in Body Composition of Patients With Obesity Related Tumors and Their Impact on Clinical Outcomes: a Multicenter Prospective Cohort Study

Over the past 20 years, China's obesity rates have surged, increasing cancer burden. Obesity links to 13 cancers via metabolic effects of visceral fat and insulin resistance, while sarcopenic obesity (BMI-independent) may worsen outcomes. Traditional BMI lacks precision; advanced methods (e.g., BIA/CT) are needed. Existing studies show inconsistent results, possibly due to heterogeneity. This multicenter prospective cohort study uses imaging to assess body composition changes (fat/muscle) in obesity-related tumors and their impact on survival, recurrence, and quality of life, and explore the underlying mechanism.
