The respiratory health effects of heated tobacco product aerosols in a primary human airway epithelial cell model

Heated-tobacco-products (HTPs) are electronic devices that "heat" a processed tobacco/chemical mixture to produce an inhalable emission. They are advertised as a reduced-risk alternative to cigarette smoking. The aim of our research was to assess their potential health impacts using a 3D human airway model.

A primary cell model of the very preterm epithelium reveals barrier defects at 1 year of age

Limited evidence suggests that airway epithelial structure and function is disrupted in very preterm infants; however, the epithelial morphology and physiology has not been well characterised following discharge from neonatal intensive care. This study aimed to characterise the nasal airway epithelium from 1-year-old survivors of very preterm birth.

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.

Draft genome sequences of the pathogenic fungi Scedosporium aurantiacum and Scedosporium apiospermum from clinical isolates

Scedosporium species are filamentous fungi with inherent broad antifungal resistance that pose opportunistic infection threats. We present draft genome assemblies of S. aurantiacum (11 contigs) and S. apiospermum (9 contigs), derived from Oxford Nanopore sequencing of one Australian clinical isolate each.

Streptococcus pyogenes Surveillance Through Surface Swab Samples to Track the Emergence of Streptococcal Toxic Shock Syndrome in Rural Japan

Japan recently experienced a record surge in streptococcal toxic shock syndrome. Our environmental surveillance study reveals that Streptococcus pyogenes persists seasonally, peaking in autumn and winter in rural Japan. The dominant emm1 M1UK sublineage and csrS mutations heighten virulence, highlighting the urgent need for targeted surveillance and interventions.

Complete genome sequence of Burkholderia cenocepacia bacteriophage Karil-mokiny-1

Burkholderia cepacia complex causes life-threatening respiratory infections. Here, a bacteriophage with activity against B. cenocepacia was isolated from wastewater. It has a genome size of 70,144 bp and has the taxonomic classification Irusalimvirus. It has no genes associated with lysogeny, bacterial resistance, or virulence. 

A Small Device May Deliver King-Sized Solutions for Patients With an Exacerbation of Cystic Fibrosis

The aim is to examine whether using a portable spring-infusor device to deliver antibiotics compared with a standard infusion pump (SIP) translated to (i) improve health outcomes, (ii) reduce the length of stay (LoS), and (iii) reduce cost for treatment of exacerbations of cystic fibrosis.

Tracing the transmission of mpox through wastewater surveillance in Southeast Asia

High population density and tourism in Southeast Asia increase the risk of mpox due to frequent interpersonal contacts. Our wastewater surveillance in six Southeast Asian countries revealed positive signals for Monkeypox virus (MPXV) DNA, indicating local transmission. This alerts clinicians and helps allocate resources like testing, vaccines and therapeutics in resource-limited countries.

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.

Azithromycin mitigates human rhinovirus impact on barrier integrity and function in non-diseased airway epithelium

Azithromycin improves symptomology in various chronic airway diseases exacerbated by viral infections. However, the mechanisms underlying the apparent antiviral effects of azithromycin remain unclear.
