To assess the predictive ability of various indicators of common bile duct calculi, 457 patients undergoing cholecystectomy for gallstone disease were prospectively screened for the presence of 11 predefined criteria of possible choledocholithiasis. The predictive ability of the criteria, individually and in combinations, was determined. For all criteria, except a history of pancreatitis, a significantly increased incidence of choledocholithiasis was found. The number of positive criteria correlated positively with the frequency of common bile duct calculi. The negative predictive value and sensitivity of the total set of criteria were 98% and 89.5%, respectively. Following common duct exploration, the number of complications and the duration of postoperative hospitalization were significantly increased as compared with simple cholecystectomy. Peroperative cholangiography with cholecystectomy is recommended in all patients, with one or more criteria of possible choledocholithiasis. Routine peroperative cholangiography in patients with no positive criteria does not seem to be necessary.

Prognosis prediction of α-FAtE score for locoregional immunotherapy in hepatocellular carcinoma.
Front Immunol
January 2025
Department of Liver Surgery, Sun Yat-sen University Cancer Center, Guangzhou, Guangdong, China.
Purpose: The α-FAtE score, composed of alpha-fetoprotein, alkaline phosphatase, and eosinophil levels, has been reported as a predictor of prognosis in hepatocellular carcinoma (HCC) patients treated with atezolizumab plus bevacizumab. This study aimed to investigate the predictive ability of α-FAtE score for the efficacy and safety of locoregional immunotherapy as the treatment of HCC patients.
Methods And Patients: We conducted a retrospective study of 446 HCC patients at Sun Yat-sen University Cancer Center from January 1 2019 to January 1 2023.
Development and validation of a glycolysis-associated gene signature for predicting the prognosis, immune landscape, and drug sensitivity in bladder cancer.
Front Immunol
January 2025
Department of Urology, The Second Hospital of Tianjin Medical University, Tianjin, China.
Background: Bladder cancer (BCa) is one of the most common malignancies worldwide, and its prognostication and treatment remains challenging. The fast growth of various cancer cells requires reprogramming of its energy metabolism using aerobic glycolysis as a major energy source. However, the prognostic and therapeutic value of glycolysis-related genes in BCa remains to be determined.

Department of Biochemistry, School of Medicine, College of Medicine, China Medical University, Taichung 404328, Taiwan.
This editorial assesses the prognostic value of preoperative inflammatory and nutritional biomarkers in patients undergoing surgical resection for pancreatic cancer. Lu evaluated the ability of seven biomarkers to predict postoperative recovery and long-term outcomes. These biomarkers were albumin-to-globulin ratio, prognostic nutritional index (PNI), systemic immune-inflammation index, neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, nutritional risk index, and geriatric nutritional risk index.

Obes Sci Pract

Department of Diabetes, Metabolism and Endocrinology Tokyo Medical University Shinjuku-ku Japan.
Objective: Waist circumference measurement is commonly used as a method for predicting the visceral fat area. However, waist circumference is difficult to measure, and there is a large margin of error between measurements. Visceral fat is adipose tissue that accumulates in the abdominal cavity, and when it accumulates in excess, abdominal computed tomography reveals a prominent protrusion of the anterior-posterior diameter of the abdomen in a coronal section at the umbilicus level.

J Vib Control
January 2025
Department of Mechanical, Industrial and Aerospace Engineering, Concordia University, Montreal, QC, Canada.
Magnetorheological (MR) fluid (MRF) dampers, serving as fail-safe semi-active devices, exhibit nonlinear hysteresis characteristics, emphasizing the necessity for accurate modeling to formulate effective control strategies in smart systems. This paper introduces a novel stop operator-based Prandtl-Ishlinskii (PI) model, featuring a reduced parameter set (seven), designed to estimate the nonlinear hysteresis properties of a large-scale bypass MRF damper with variable stiffness capabilities under varying applied current. With only seven parameters, the model realizes current, displacement, and rate dependencies.
