Respiratory and chest wall mechanics in very preterm infantsData on static compliance of the chest wall (Ccw) in preterm infants are scarce. We characterized the static compliance of the lung and Ccw to determine their relative contribution to static compliance of the respiratory system in very preterm infants at 36 wk postmenstrual age. We also aimed to investigate how these compliances were influenced by the presence of bronchopulmonary dysplasia and impacted breathing variables.

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

Lentiviral vector gene therapy and CFTR modulators show comparable effectiveness in cystic fibrosis rat airway modelsMutation-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.

In utero and early-life nitrate in drinking water impacts lung function of weanling ratsConsumption of nitrate in drinking water has previously been associated with a range of adverse health effects, including methemoglobinemia and potentially cancer. In animal models, it has been shown to impact respiratory structure and function, however, there is a paucity of data of the effects of in utero exposure on the respiratory health of offspring.

COMBAT CF is one of two long-standing international trials which have resulted in new early intervention options helping to reduce progressive lung damage in kids living with CF.

A public health campaign to raise awareness about the dangers of chronic wet cough in Aboriginal children is helping to improve detection, diagnosis and management of the condition.

Ca-EDTA restores the activity of ceftazidime-avibactam or aztreonam against carbapenemase-producing Klebsiella pneumoniae infectionsDeveloping an effective therapy to overcome carbapenemase-positive Klebsiella pneumoniae (CPKp) is an important therapeutic challenge that must be addressed urgently. Here, we explored a Ca-EDTA combination with aztreonam or ceftazidime-avibactam in vitro and in vivo against diverse CPKp clinical isolates.

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