Bacterial infections in wounds continue to be a major challenge in clinical settings worldwide and represent a significant threat to human health. This work proposes novel expandable and versatile methods for solidifying sodium alginate (SA) with metal ions (such as Fe, Co, Ni, Cu, and Zn) to create Metal-Alginate (M-Alg) hydrogel with adjustable morphology, composition, and microstructure. It conforms to the wound site, protects against second infection, reduces inflammation, and promotes the healing of infected wounds. Among these hydrogels, Cu-Alginate (Cu-Alg) shows excellent sterilization effect and good efficacy against both gram-positive and gram-negative bacteria, including multidrug-resistant (MDR) strains such as Methicillin-resistant Staphylococcus aureus (MRSA) and Carbapenem-resistant Klebsiella pneumoniae (CRKP) due to its dual antibacterial mechanisms: contact-killing and reactive oxygen species (ROS) burst. Importantly, it exhibits low cytotoxicity and biodegradability. This simple and cost-effective gel-based system has the potential to introduce an innovative approach to the management of wound infection and offers promising new perspectives for the advancement of wound care practice.

Diabetic wound healing remains a major challenge in modern medicine. The persistent inflammation and immune dysfunction hinder angiogenesis by producing excessive ROS and increasing the susceptibility to bacterial infection. In this study, we developed an integrated strategy for whole-process management of diabetic wounds based on a bioinspired adhesive hydrogel platform with hemostasis, photothermal antimicrobial, antioxidant, anti-inflammatory, and angiogenic properties.

Backgroud: Intervertebral disc degeneration (IDD) is one of the common degenerative diseases. Due to ethical constraints, it is difficult to obtain sufficient research on humans, so the use of an animal model of IDD is very important to clarify the pathogenesis and treatment mechanism of the disease.
Methods: In this study, thirty 2-month-old mice were selected for operation to establish a coccygeal IDD model.

Background: Deep sternal wound infection (DSWI) is a severe and life-threatening complication following cardiovascular surgery. Negative pressure wound therapy (NPWT) has emerged as a promising therapeutic bridging option for DSWI. In this systematic review and meta-analysis, the authors aimed to evaluate the impact of NPWT on clinical outcomes in patients with DSWI.

Introduction: Postoperative infections are a leading cause of morbidity following fracture repair. The purpose of this study is to develop a risk score predicting fracture-related infection (FRI) that will require one versus multiple revision surgeries related to infection eradication and bone healing.
Methods: This is a retrospective cohort study conducted at a single level I trauma center from 2013 to 2020.
