Developing a predictive model for delayed healing of esophagojejunal anastomotic fistula following total gastrectomy based on imaging and clinical inflammatory-nutritional status.

Background: Esophagojejunal anastomotic fistula (EJF) following radical total gastrectomy is a severe perioperative complication in patients with gastric cancer, particularly as delayed fistula healing increases hospitalization costs and leads to poor prognosis. Numerous factors influence the occurrence and progression of EJF, with inflammation and nutritional status being significant contributors to perioperative complications. Therefore, this study aims to investigate the prediction of delayed EJF healing based on postoperative clinical and imaging-related inflammation-nutrition status.

Optimizing Surgery for Idiopathic Scoliosis: Does a Dual Approach Help Young Surgeons?

Introduction In idiopathic scoliosis surgery, studies have shown two attending surgeons have better curve correction, pain, and recovery time. There is conflicting evidence on operative time, blood loss, infection rate, and hospital length of stay. Limited literature examines the impact of surgeon experience on the dual approach.

Integrating spatial clustering and multi-source geospatial data for comprehensive geological hazard modeling in Hunan Province.

This study presents an integrated framework that combines spatial clustering techniques and multi-source geospatial data to comprehensively assess and understand geological hazards in Hunan Province, China. The research integrates self-organizing map (SOM) and geo-self-organizing map (Geo-SOM) to explore the relationships between environmental factors and the occurrence of various geological hazards, including landslides, slope failures, collapses, ground subsidence, and debris flows. The key findings reveal that annual average precipitation (Pre), profile curvature (Pro_cur), and slope (Slo) are the primary factors influencing the composite geological hazard index (GI) across the province.

Glycerol-Derived Water-Lean Amines for Post-Combustion CO2 Capture: The Improvement in Capacity and Viscosity.

Water-lean absorbents are regarded as a new generation of post-combustion CO2 capture technology that could significantly relieve those drawbacks posed by traditional aqueous alkanolamines. However, the exponential increase in viscosity during CO2 absorption remains an urgent issue that needs to be resolved before their practical deployment. In this work, novel water-lean amines based on biomass glycerol have been devised as single-component CO2 absorbents with low viscosity (79~110 cP at 25 oC, 29~39 cP at 40 oC) under high capacity (12~18 wt% at 25 oC, 10~17 wt% at 40 oC).
