Changes in airway inflammation with pseudomonas eradication in early cystic fibrosis

Neutrophil elastase is a significant risk factor for structural lung disease in cystic fibrosis, and Pseudomonas aeruginosa airway infection is linked with neutrophilic inflammation and substantial respiratory morbidity. We aimed to evaluate how neutrophil elastase (NE) activity changes after P. aeruginosa eradication and influences early disease outcomes. We assessed participants in the AREST CF cohort between 2000 and 2018 who had P. aeruginosa cultured from their routine annual bronchoalveolar lavage (BAL) fluid and who underwent eradication treatment and a post eradication BAL. Factors associated with persistent P. aeruginosa infection, persistent neutrophilic inflammation following eradication and worse structural lung disease one year post-eradication were evaluated.

Lytic activity, stability, biofilm disruption capabilities and genomic characterisation of two bacteriophages active against respiratory MRSA

This study aimed to characterise bacteriophages for potential therapeutic use against Staphylococcus aureus, focusing on clinical respiratory isolates of methicillin-sensitive (MSSA) and methicillin-resistant (MRSA) strains. Specifically, it sought to evaluate phage lytic activity, host range, stability, biofilm disruption capabilities, and overall safety for therapeutic use.

Combination of curcumin or chitosan with photodynamic therapy as an effective alternative therapy for overcoming wound infection associated with multidrug-resistant Acinetobacter baumannii

The increasing prevalence of multidrug-resistant Acinetobacter baumannii as an opportunistic pathogen in wound infections raises significant concerns due to its antibiotic resistance and biofilm-mediated antibiotic tolerance. This underscores the urgent need to explore an alternative approach to effectively managing wound infections caused by MDR A. baumannii.

Epithelial Drivers of Neutrophil Plasticity in Early Cystic Fibrosis Lung Disease

Hallmarks of cystic fibrosis (CF) airway disease include bronchiectasis, airway inflammation by infiltrating polymorphonuclear neutrophils (PMNs) and recurring infection.

WA Epithelial Research Program for Childhood Respiratory Diseases

Once thought to be a simple barrier to the external environment, epithelial cells are involved in many repair and inflammatory processes that occur in childhood airway diseases.

Viral Induced Effects on a Vulnerable Epithelium; Lessons Learned From Paediatric Asthma and Eosinophilic Oesophagitis

The epithelium is integral to the protection of many different biological systems and for the maintenance of biochemical homeostasis. Emerging evidence suggests that particular children have epithelial vulnerabilities leading to dysregulated barrier function and integrity, that resultantly contributes to disease pathogenesis.

Global participatory wastewater surveillance to understand mpox clade diversity in war and conflict-affected countries

War and conflict severely disrupt public health systems, compromising infectious disease surveillance in many affected regions. Mpox, a re-emerging zoonotic disease, poses a growing global threat, especially in areas where traditional monitoring is inaccessible.The mpox virus has distinct clades with varying transmission and severity.
