Analysis of risk factors for surgical site infection in spinal surgery patients and study of direct economic losses.

Background: Surgical site infection (SSI) is a serious complication of spine surgery, leading to prolonged hospital stays, re-operations, and economic losses. The aim of the study was to explore the types and quantities of pathogenic bacteria involved, the incidence of SSI, and to identify the independent risk factors and direct economic impact on patients with postoperative SSI in spine surgery.

Methods: The medical records of spine surgery patients from January 2023 to April 2024 at two hospitals in Xinjiang were retrospectively reviewed.

Determining the Disinfectants Resistance Genes and the Susceptibility to Common Disinfectants of Extensively Drug-Resistant Carbapenem-Resistant Strains at a Tertiary Hospital in China.

Carbapenem-resistant (CRKP) infection has become a significant threat to global health. The application of chemical disinfectants is an effective infection control strategy to prevent the spread of CRKP in hospital environments. However, bacteria have shown reduced sensitivity to clinical disinfectants in recent years.

Efficacy of Random Forest Models in Predicting Multidrug-Resistant Gram-Negative Bacterial Nosocomial Infections Compared to Traditional Logistic Regression Models.

This study evaluates whether random forest (RF) models are as effective as traditional Logistic Regression (LR) models in predicting multidrug-resistant Gram-negative bacterial nosocomial infections. Data were collected from 541 patients with hospital-acquired Gram-negative bacterial infections at two tertiary-level hospitals in Urumqi, Xinjiang, China, from August 2022 to November 2023. Relevant literature informed the selection of significant predictors based on patients' pre-infection clinical information and medication history.

Enhanced removal of methylene blue from wastewater by alginate/carboxymethyl cellulose-melamine sponge composite.

Industrial dye wastewater poses a threat to human health due to its harmful effects, and the treatment of related wastewater is receiving increasing attention. In this paper, the melamine sponge with high porosity and convenient separation was selected as matrix material, and alginate/carboxymethyl cellulose-melamine sponge composite (SA/CMC-MeS) was prepared through crosslinking strategy. Not only does the composite cleverly combined the merits of alginate and carboxymethyl cellulose, it also enhanced the adsorption performance for methylene blue (MB).
