Regulating the Irregular: Phage Therapy and the Case for a Regulatory Sandbox Approach in Australia

Bacteriophages (phages) are viruses that selectively kill bacteria and offer a promising option to address the growing global pandemic of antimicrobial-resistant infections. However, phage therapy does not easily align with traditional regulatory pathways designed for fixed-composition chemical drugs or biologics with fixed non-evolving compositions.

Toxicity of plastic diesel exhaust in primary human airway epithelial cell cultures

Plastic pyrolysis oil, which can be produced with similar properties as diesel fuel (plastic diesel), can be used as an alternative to mineral diesel (ULSD) to run a diesel engine. This presents a potential method for recycling waste plastic. Typically plastic diesel is blended with mineral diesel, and oxygenated fuel additives such as ethers added to improve resulting fuel properties. 

Stochastic models indicate rapid smallpox spread and mass mortality of Indigenous Australians after colonial exposure

The impact of smallpox (variola) on Aboriginal communities in Australia beginning in 1789 was catastrophic and continues to cause intergenerational trauma. Historically biased perspectives and contemporary misinformation of the disease's introduction and spread impede modern-day truth-telling and efforts towards reconciliation and national healing.

Personal network inference identifies children at risk of recurrent wheezing and asthma

Wheezing and asthma exacerbations are leading causes of pediatric hospital admissions. Predicting which children will experience persistent exacerbations remains challenging. Prior research has identified immune endotypes in the nasal epithelium of children with acute asthma and wheezing, characterized by varying balances of interferons and inflammatory markers. Notably, children exhibiting low interferon responses coupled with high inflammation are at an increased risk for recurrent respiratory exacerbations.

Strengthening Aboriginal family involvement in the paediatric ESCALATION system: A multi-methods study of Aboriginal families' experiences in raising concerns

To explore Aboriginal families' experiences of recognising clinical deterioration and raising their concerns within the Paediatric ESCALATION system to identify enablers and barriers to family involvement.

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.

Tracking Plasmodium knowlesi through faecal DNA for monitoring zoonotic transmission in wild macaques across Southeast and South Asia

We conducted the non-invasive surveillance of Plasmodium knowlesi in wild macaques using 4,752 faecal samples collected across nine endemic countries. 

High prevalence of mgrB-mediated colistin resistance among carbapenem-resistant Klebsiella pneumoniae is associated with biofilm formation, and can be overcome by colistin-EDTA combination therapy

The global prevalence of colistin-resistant Klebsiella pneumoniae (ColRkp) facilitated by chromosomal and plasmid-mediated Ara4N or PEtN-remodeled LPS alterations has steadily increased with increased colistin usage for treating carbapenem-resistant K. pneumoniae (CRkp).

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.

Progress in Model Systems of Cystic Fibrosis Mucosal Inflammation to Understand Aberrant Neutrophil Activity

Here we examine the latest findings of neutrophils in pediatric CF lung disease and proposed mechanisms of their pathogenicity
