High-frequency oscillatory ventilation (HFOV) is an established mode of respiratory support in the neonatal intensive care unit. Large clinical trial data is based on first intention use in preterm infants with acute respiratory distress syndrome. Clinical practice has evolved from this narrow population. HFOV is most often reserved for term and preterm infants with severe, and often complex, respiratory failure not responding to conventional modalities of respiratory support.
Chorioamnionitis is a common antecedent of preterm birth and induces inflammation and oxidative stress in the fetal lungs. Reducing inflammation and oxidative stress in the fetal lungs may improve respiratory outcomes in preterm infants. Creatine is an organic acid with known anti-inflammatory and antioxidant properties.
Bronchiectasis is a worldwide chronic lung disorder where exacerbations are common. It affects people of all ages, but especially Indigenous populations in high-income nations. Despite being a major contributor to chronic lung disease, there are no licensed therapies for bronchiectasis and there remain relatively few randomised controlled trials (RCTs) conducted in children and adults.
Preterm birth is associated with increased mortality and morbidity, particularly due to lung disease. Low- and middle-income countries (LMIC) have the highest rates of preterm birth. Infants born extremely preterm rarely survive, so the largest burden is amongst moderate-to-late preterm (MLP) infants. The long-term health impact on MLP children in LMIC is poorly understood. The aim of this study was to assess the effect of MLP birth on lung function trajectories from birth to 5 years in the Drakenstein Child Health Study.
Early childhood wheeze is a major risk factor for asthma. However, not all children who wheeze will develop the disease. The airway epithelium has been shown to be involved in asthma pathogenesis. Despite this, the airway epithelium of children with acute wheeze remains poorly characterized.
During exacerbations, when symptom and treatment burden are increased, individuals with cystic fibrosis (CF) are likely to prefer airway clearance techniques (ACTs) that require minimal effort. Therefore, in adults with CF who were hospitalised with an exacerbation, we sought to compare the effect of the MetaNeb with usual ACTs on respiratory function and expectorated sputum.
Children with wheeze and asthma present with airway epithelial vulnerabilities, such as impaired responses to viral infection. It is postulated that the in utero environment may contribute to the development of airway epithelial vulnerabilities.
We present lung virome data recovered through shotgun metagenomics in bronchoalveolar lavage fluid from an infant with cystic fibrosis, who tested positive for Stenotrophomonas maltophilia infection. Using a bioinformatic pipeline for virus characterization in shotgun metagenomic data, we identified five viral contigs representing Pseudomonas phages classified as Caudoviricetes.
The earliest respiratory function assessments, within or close to the neonatal period, consistently show correlations with lung function and with the development of asthma into adulthood. Measurements of lung function in infancy reflect the in utero period of lung development, and if early enough, show little influence of postnatal environmental exposures.
To estimate the developmental trends of quantitative parameters obtained from chest computed tomography (CT) and to provide normative values on dimensions of bronchi and arteries, as well as bronchus-artery (BA) ratios from preschool age to young adulthood.
