AIM:To elucidate the influence of liver cirrhosis(LC) on the prognosis of patients with gastric cancer(GC).METHODS:Of the 1347 GC patients who underwent curative gastrectomy for GC between January 1984 and June 2007,25 patients(21 men and 4 women with a median age of 67 years;range 54-77 years) with LC were enrolled in this *** the Child-Pugh classification,15 patients were evaluated as grade A and 10 patients as grade *** grade C patient underwent gastrectomy in this *** outcomes,including postoperative morbidity and survival,were retrospectively analyzed based on medical records and surgical f ***:There was no significant difference in operative blood loss and perioperative blood transfusion between the two *** most common postoperative complication was intractable ascites,which was the single postoperative morbidity noted more frequently in grade B patients(40.0%) than in grade A patients(6.7%) with statistical signif icance(P = 0.041).Operative mortality due to hepatic failure was seen in one grade A *** patients had hepatocellular carcinoma(HCC) at presentation and two patients developed HCC after *** 5-year survival rate was 58.9% in patients with early GC and 33.3% in patients with advanced GC(P = 0.230).GC-specific 5-year survival rate of early GC patients was 90.0% while that of advanced GC patients was 58.3%(P = 0.010).Four patients with early GC died of uncontrolled HCC,of which two were synchronous and two ***:The risk of postoperative intractable ascites is high,particularly in grade B *** detection and complete control of HCC is vital to improve a patient's prognosis.

Energy exchange between charged relativistic fluids in f(T) gravity

Communications in Theoretical Physics 2024年第10期 108-120页

作者： Z Yousaf U A Khokhar Nasser Bin Turki T suzuki Department of Mathematics University of the Punjab Quaid-i-Azam Campus Department of Mathematics College of Science King Saud University Department of Regional Management Faculty of Management Fukushima College

This study focuses on the effects of a polytropic fluid on a charged gravitational source within f(T) gravity, where T is the torsion scalar. We investigate how the electromagnetic field affects the flow of energy in spherically symmetric and static celestial objects that contain relativistic fluids. By using the gravitational decoupling technique, we analyze the effects of polytropic fluid on the dynamics of the gravitational source, accompanied by the matching of the interior geometry with an exterior at the hypersurface Σ. Finally, with the help of the Tolman ⅡV solution, we observe the conduct of energy conditions with the existence of charge using f(T)field equations and got the intended outcomes.
