People born preterm (<37 weeks’ gestation) have lower peak oxygen consumption (peak VO2), a well-established indicator of long-term health outcomes, compared to term-born peers. However, responses to exercise can vary with exercise mode, which has implications for prognostic assessments. 

Limited evidence suggests that airway epithelial structure and function is disrupted in very preterm infants; however, the epithelial morphology and physiology has not been well characterised following discharge from neonatal intensive care. This study aimed to characterise the nasal airway epithelium from 1-year-old survivors of very preterm birth.

Survivors of preterm birth (<37 weeks' gestation) have low peak oxygen uptake, a global measure of aerobic fitness and an established predictor of increased morbidity and mortality. However, little is known about other cardiopulmonary outcome measures in this population. We addressed the hypothesis that preterm birth is associated with abnormal respiratory, cardiovascular and metabolic responses to exercise, as assessed by cardiopulmonary exercise testing, via a systematic review and meta-analysis.

Clinical utility of home polysomnography in children with neuromuscular disorders is limited by lack of evidence that sleep-disordered breathing can be reliably identified and inability to diagnose hypoventilation because carbon dioxide is not measured.

There is no published information on preterm children's activities and participation during middle childhood, a time when growth and development are characterised by increasing motor, reasoning, self-regulation, social and executive functioning skills. This study explored the health, activities and participation of children born very preterm during middle childhood (6-9 years) from the perspectives of their parents.

Small airway and lung parenchymal abnormalities frequently occur following preterm birth but are commonly missed by spirometry. Static lung volumes, diffusing capacity of the lung for carbon monoxide (D LCO) and oscillometry provide a more precise characterisation of these conditions. We hypothesised that differences in these measures exist between individuals born preterm and at term and we aimed to systematically review the literature to identify and quantify these differences in lung function.

Mucus plugs have been previously recognized as an important pathological feature in asthma and chronic obstructive pulmonary disease (COPD), but their clinical role in these diseases has not been explored in depth until recently. Mucus plug formation is driven by mucus hyperconcentration, changes in mucus viscoelastic properties, impaired clearance, and mucociliary collapse. 

Nasal epithelial cells from young adults with a history of very preterm birth show delayed closure following scratch-wounding. Repair correlated with lung function, suggesting epithelial barrier integrity may play a role in preterm-associated lung disease.

Sleep problems occur in up to 20%-45% of adolescents. This systematic review and meta-analysis examined the effectiveness of digital sleep interventions, based on cognitive behavioural therapy for insomnia, for adolescents with insomnia symptoms. The objective was to synthesise and quantify, through meta-analyses, changes in sleep following completion of a digital sleep-based intervention.
