Preparation of antibacterial cellulose nanocrystals-graft-poly[2-(tert-butylamino) ethyl methacrylate] nanoparticles and their applications on creating wound dressings with a bacterial shielding property.

Bacterial infections in wounds, especially in patients with chronic conditions like diabetic wounds, pose significant treatment challenges. Addressing the susceptibility to infection is crucial, and the development of functional dressings to prevent bacterial invasion has proven a promising strategy. Cellulose nanocrystals (CNCs), derived from bio-resources and functioning as nanoparticles (NPs), were modified with poly[2-(tert-butylamino) ethyl methacrylate] (PTA) through atom transfer radical polymerization (ATRP) to create CNCs-graft-PTA NPs (CNPs).

Photothermal-responsive nanocomposite injectable hydrogel capable of programed peroxidase-mimicking catalysis and immunomodulation and revascularization enables efficient drug-resistant bacterial elimination and comprehensive tissue regeneration.

Intractable infected wound caused by drug-resistant bacteria remains a severe healthcare problem. Reactive oxygen species (ROS)-based nanocatalytic therapy (ROS-NT) is harnessed to combat drug-resistant bacterial infection. However, it can also cause immune imbalance and excessive inflammatory responses, postponing subsequent wound healing process.

Effects of enteral immunonutrition in laparoscopic versus open resections in colorectal cancer surgery: A meta-analysis of randomised controlled trials.

Introduction: Immunonutrition (IMN) modulates the activity of the immune system. However, the effects of IMN on cancer patients following colorectal surgery is still lacking. We performed a systematic review and meta-analysis to evaluate the outcomes of IMN in patients undergoing laparoscopic versus open colorectal surgery.

Efficient Photolysis of Multidrug-Resistant Polymicrobial Biofilms.

Chronic wounds are prone to infections with multidrug-resistant bacteria, forming polymicrobial biofilms that limit treatment options and increase the risk of severe complications. Current cleansing options are insufficient to disrupt and remove tenacious biofilms; antibiotic treatments, on the other hand, often fall short against these biofilm-embedded bacteria. This study explores an non-antibiotic approach that extends beyond conventional porphyrin-based phototherapy by using blue light (BL) in conjunction with ferric ions (Fe(III)) to disrupt and eradicate biofilms.

Clinically relevant evaluation of the antimicrobial and anti-inflammatory properties of nanocrystalline and nanomolecular silver.

Burns and chronic wounds present significant challenges in wound management due to risks of infection, excessive inflammation, and prolonged healing. Silver-based treatments have long been central to burn care, but limitations have prompted the exploration of nanocrystalline silver as an alternative, with its nanoscale properties offering distinct benefits. This paper reviews the structure, properties, mechanisms of action, and clinical applications of nanocrystalline silver in burn and general wound management, with particular emphasis on how wound healing processes inform the application of these dressings.

Global surgery is stronger when infection prevention and control is incorporated: a commentary and review of the surgical infection landscape.

Incorporating infection prevention and control (IPC) is crucial for strengthening global surgery, particularly in low- and middle-income countries (LMICs). This review article highlights the critical role IPC plays in ensuring equitable and sustainable surgical care, aligning with the Sustainable Development Goals (SDG) 3 and 10, which aim to promote health and reduce inequalities. Surgical site infections (SSIs) and other healthcare-associated infections (HAIs) disproportionately affect LMICs, where IPC infrastructure is often underdeveloped.

Development of a novel nomogram for the prediction of surgical site infection risk after loop ileostomy closure.

Background: A postoperative surgical site infection (SSI) is a prevalent complication after loop ileostomy closure. There are few studies on the risk factors and the development of predictive models for postoperative SSIs. The aim of this study was to develop and validate a nomogram model capable of accurately predicting the occurrence of postoperative SSIs.

Development and validation of a preoperative systemic inflammation-based nomogram for predicting surgical site infection in patients with colorectal cancer.

Background: Surgical site infection (SSI) represents a significant postoperative complication in colorectal cancer (CRC). Identifying associated factors is therefore critical. We evaluated the predictive value of clinicopathological features and inflammation-based prognostic scores (IBPSs) for SSI occurrence in CRC patients.

Topical Vancomycin Paste Over the Sternal Edge During Cardiac Surgery: Effects of Renal Function and Body Size on Systemic Exposure.

Purpose: Intraoperative topical vancomycin has been widely used in several surgical fields to prevent wound infection. However, there have been limited studies on the systemic exposure of topical vancomycin. The aim of this study was to investigate systemic exposure after topical vancomycin over the sternal edge in cardiac surgical patients.

In-situ Oxygen-Supplying ROS Nanopurifier for Enhanced Healing of MRSA-Infected Diabetic Wounds via Microenvironment Modulation.

Hypoxia, high ROS levels and chronic inflammation are the main factors that hinder the healing of diabetic wounds. Long-term exposed wounds are prone to bacterial infection, especially MRSA infection, which exacerbates the complex wound microenvironment of diabetes and threatens patients' lives. Here, we developed a ROS nanopurifier (CSVNP), which was prepared by loading superoxide dismutase (SOD), catalase (CAT) and vancomycin into nanogels through in-situ polymerization.

Cause and Effect of Revisions in Adult Spinal Deformity Surgery: A Multicenter Study on Outcomes Based on Etiology.

Background Context: While the treatment of adult spinal deformity (ASD) has increasingly favored surgical correction, the incidence of revision surgery remains high. Yet, little has been explored on the association between the etiology of reoperation and patient outcomes.

Purpose: To assess the impact of the etiology of revision surgery on postoperative outcomes.

Preparation of biodegradable, antibacterial core-spun yarns with braided structures using QAS/PLA micro/nanocomposites.

Medical antibacterial textiles play a vital role in tackling the issue of bacterial infection. Traditional surgical sutures face significant challenges due to wound infection caused by bacteria and breakage and scars caused by poor suture strength. Therefore, a new antibacterial and high-strength suture preparation strategy with wide clinical applicability was highly desired.

Cationic conjugated polymers with tunable hydrophobicity for efficient treatment of multidrug-resistant wound biofilm infections.

Biofilm-associated infections arising from antibiotic-resistant bacteria pose a critical challenge to global health. We report the generation of a library of cationic conjugated poly(phenylene ethynylene) (PPE) polymers featuring trimethylammonium terminated sidechains with tunable hydrophobicity. Screening of the library identified an amphiphilic polymer with a C hydrophobic spacer as the polymer with the highest antimicrobial efficacy against biofilms in the dark with excellent selectivity.

An injectable sodium-mangiferin homopolymeric hydrogel accelerated skin full-thickness wound healing in guinea pig model.

In the treatment of joints, mucosa, and full-thickness wounds, traditional implant surgery presents not only inconvenience but also a significant risk of wound infection. Additionally, the pharmaceutical application of mangiferin(MGF) has been severely restricted due to its poor water solubility. In this study, we reported the synthesis and characterization of sodium-mangiferin (MGF-Na(S)) using the salt formation method.
