Directing immune development to curb sky-rocketing disease

Once upon a time it was infectious diseases like polio, measles or tuberculosis that most worried parents. With these threats now largely under control, parents face a new challenge – sky-rocketing rates of non-infectious diseases such as asthma, allergies and autism.

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.

Bile acids in the lower airways is associated with airway microbiota changes in chronic obstructive pulmonary disease: an observational study

Chronic obstructive pulmonary disease (COPD) is a complex disorder with a high degree of interindividual variability. Gastrointestinal dysfunction is common in patients with COPD and has been proposed to influence the clinical progression of the disease. Using the presence of bile acid(s) (BA) in bronchoalveolar lavage (BAL) fluid as a marker of gastric aspiration, we evaluated the relationships between BAs, clinical outcomes and bacterial lung colonisation.

Inhaled nebulised adrenaline delivery in children and adults: A simulation study

Sometimes, there is an urgent need to administer inhaled adrenaline to children, awake, sedated or anaesthetised to treat asthma, bronchospasm, croup, and suspected laryngeal/pharyngeal oedema or stridor, which can become severe or even life-threatening. To better inform emergency dosing and administration guidelines, we aimed to quantify the amount of adrenaline delivered for inhalation from a nebuliser, in a simulated experimental delivery set-up for spontaneously breathing children and adults, either via an anaesthetic face mask, a Laryngeal Mask Airway or an Endotracheal tube.

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.

Lentiviral vector gene therapy and CFTR modulators show comparable effectiveness in cystic fibrosis rat airway models

Mutation-agnostic treatments such as airway gene therapy have the potential to treat any individual with cystic fibrosis (CF), irrespective of their CF transmembrane conductance regulator (CFTR) gene variants. The aim of this study was to employ two CF rat models, Phe508del and CFTR knockout to assess the comparative effectiveness of CFTR modulators and lentiviral vector-mediated gene therapy. 

Transcriptomic analysis of primary nasal epithelial cells reveals altered interferon signalling in preterm birth survivors at one year of age

Many survivors of preterm birth (<37 weeks gestation) have lifelong respiratory deficits, the drivers of which remain unknown. Influencers of pathophysiological outcomes are often detectable at the gene level and pinpointing these differences can help guide targeted research and interventions. This study provides the first transcriptomic analysis of primary nasal airway epithelial cells in survivors of preterm birth at approximately 1 year of age.

Vitamin D and atopy and asthma phenotypes in children: a longitudinal cohort study

Vitamin D has been linked in some studies with atopy- and asthma-associated phenotypes in children with established disease,but its role in disease inception...

Cyanide in bronchoalveolar lavage is not diagnostic for Pseudomonas aeruginosa in children with cystic fibrosis

We investigated whether cyanide in bronchoalveolar lavage (BAL) fluid could be used as an early diagnostic biomarker of infection in kids with cystic fibrosis

Innate inflammatory responses of pediatric cystic fibrosis airway epithelial cells: Effects of nonviral and viral stimulation

There is controversy regarding whether cystic fibrosis (CF) airway epithelial cells (AECs) are intrinsically proinflammatory.
