RESUMEN
Patients undergoing anthracycline-based cancer treatments have an increased risk of heart failure (HF) and adverse metabolic outcomes such as malnutrition and cachexia. This retrospective study explored the impact of sodium-glucose co-transporter 2 inhibitors (SGLT2i) on these outcomes in HF patients previously treated with anthracyclines. Using the TriNetx research network, we identified 1,545 patients with a history of SGLT2i use and 17,681 without. We then performed 1:1 propensity score matching resulting in 1,323 patients within each cohort. Patients were analyzed over a 5-year period. SGLT2i use was associated with significantly reduced risks of cachexia (HR 0.453, 95% CI [0.286-0.718]), malnutrition (HR 0.702, 95% CI [0.547-0.900]), adult failure to thrive (HR 0.489, 95% CI [0.345-0.693]), and all-cause mortality (HR 0.490, 95% CI [0.423-0.568]). These findings call for additional research to determine whether SGLT2i may indeed improve nutritional status and survival in patients receiving anthracycline therapy.
RESUMEN
Partial 2/3 hepatectomy in mice is used in research to study the liver's regenerative capacity and explore outcomes of liver resection in a number of disease models. In the classical partial 2/3 hepatectomy in mice, two of the five liver lobes, namely the left and median lobes representing approximately 66% of the liver mass, are resected en bloc with an expected postoperative survival of 100%. More aggressive partial hepatectomies are technically more challenging and hence, have seldom been used in mice. Our group has developed a mouse model of an extended hepatectomy technique in which three of the five liver lobes, including the left, median, and right upper lobes, are resected separately to remove approximately 78% of the total liver mass. This extended resection, in otherwise healthy mice, leaves a remnant liver that cannot always sustain adequate and timely regeneration. Failure to regenerate ultimately results in 50% postoperative lethality within 1 week due to fulminant hepatic failure. This procedure of extended 78% hepatectomy in mice represents a unique surgical model for the study of small-for-size syndrome and the evaluation of therapeutic strategies to improve liver regeneration and outcomes in the setting of liver transplantation or extended liver resection for cancer.
