Substrate-dependent metabolomic signatures of myeloperoxidase activity in airway epithelial cells: Implications for early cystic fibrosis lung disease

Myeloperoxidase is released by neutrophils in inflamed tissues. MPO oxidizes chloride, bromide, and thiocyanate to produce hypochlorous acid, hypobromous acid, and hypothiocyanous acid, respectively. These oxidants are toxic to pathogens, but may also react with host cells to elicit biological activity and potential toxicity. In cystic fibrosis and related diseases, increased neutrophil inflammation leads to increased airway MPO and airway epithelial cell exposure to its oxidants.

Characteristics, treatment and lung function outcomes of pulmonary exacerbations in cystic fibrosis: insights from the BEAT-CF cohort

Pulmonary exacerbations pose a significant clinical burden on people with cystic fibrosis (pwCF). Whether management of exacerbations should change in the context of modulator therapy is unclear. We describe the characteristics, treatment and lung function outcomes of pulmonary exacerbations requiring intravenous antibiotic therapy (PERITs) in a contemporary Australian cohort of pwCF, in an era of rapidly broadening access to modulator therapy.

Young children with cystic fibrosis and tracheobronchomalacia have longer and more frequent hospital admissions

Tracheobronchomalacia (TBM) is characterised by abnormal collapsibility of the trachea and bronchi, often seen in children with cystic fibrosis (CF). This study aims to determine the impact of TBM on hospital admissions in young children with CF.

The feasibility of using electrical impedance tomography to guide positive pressure airway clearance in children with cystic fibrosis and tracheobronchomalacia

Positive expiratory pressure devices are frequently used for airway clearance in children with cystic fibrosis and tracheobronchomalacia. This study aimed to establish if electrical impedance tomography is a feasible measure to titrate pressures in non-sedated children.

Child health a focus in national research grants

The Kids Research Institute Australia researchers have been awarded more than $8 million in prestigious project grants from the NHMRC.

A screening tool to identify risk for bronchiectasis progression in children with cystic fibrosis

The marked heterogeneity in cystic fibrosis (CF) disease complicates the selection of those most likely to benefit from existing or emergent treatments. We aimed to predict the progression of bronchiectasis in preschool children with CF.

Multilocus Sequence Typing Reveals Extensive Genetic Diversity of the Emerging Fungal Pathogen Scedosporium aurantiacum

Scedosporium spp. are the second most prevalent filamentous fungi after Aspergillus spp. recovered from cystic fibrosis (CF) patients in various regions of the world. Although invasive infection is uncommon prior to lung transplantation, fungal colonization may be a risk factor for invasive disease with attendant high mortality post-transplantation. Abundant in the environment, Scedosporium aurantiacum has emerged as an important fungal pathogen in a range of clinical settings.

Quality of life is poorly correlated to lung disease severity in school-aged children with cystic fibrosis

There is no data exclusively on the relationship between health-related quality-of-life (HRQOL) and lung disease severity in early school-aged children with cystic fibrosis (CF). Using data from the Australian Respiratory Early Surveillance Team for Cystic Fibrosis (AREST CF) we assessed the relationships between HRQOL, lung function and structure.

Methods used to evaluate the immediate effects of airway clearance techniques in adults with cystic fibrosis: A systematic review and meta-analysis

This review reports on methods used to evaluate airway clearance techniques (ACT) in adults with CF and examined data for evidence of any effect. Sixty-eight studies described ACT in adequate detail and were included in this review.

Novel method to select meaningful outcomes for evaluation in clinical trials

A standardised framework for selecting outcomes for evaluation in trials has been proposed by the Core Outcome Measures in Effectiveness Trials working group. However, this method does not specify how to ensure that the outcomes that are selected are causally related to the disease and the health intervention being studied. Causal network diagrams may help researchers identify outcomes that are both clinically meaningful and likely to be causally dependent on the intervention, and endpoints that are, in turn, causally dependent on those outcomes.
