Effect of posture on lung ventilation distribution and associations with structure in children with cystic fibrosis

Background: We assessed the effect of posture on ventilation distribution and the impact on associations with structural lung disease.

Research

Nasal airway epithelial repair after very preterm birth

Nasal epithelial cells from very preterm infants have a functional defect in their ability to repair beyond the first year of life, and failed repair may be associated with antenatal steroid exposure.

Research

Laryngeal reflex responses in pediatric anesthesia

Laryngeal and respiratory reflexes are vitally important defense mechanisms against foreign body aspiration, safeguarding airway patency, and ventilation

Research

Variants associated with HHIP expression have sex-differential effects on lung function

Lung function is highly heritable and differs between the sexes throughout life. However, little is known about sex-differential genetic effects on lung function. We aimed to conduct the first genome-wide genotype-by-sex interaction study on lung function to identify genetic effects that differ between males and females.

Research

Association between diesel engine exhaust exposure and lung function in Australian gold miners

Diesel engine exhaust exposures were higher in underground miners and had a negative association with their lung function over a single 12-h shift

Research

Bronchodilator responsiveness in children with asthma is not influenced by spacer device selection

Spacer device was not associated with clinically important differences in lung function following bronchodilator inhalation in children with asthma

Research

Bronchopulmonary dysplasia: Rationale for a pathophysiological rather than treatment based approach to diagnosis

This review describes the evolution of bronchopulmonary dysplasia definitions, evaluates the benefits and limitations of each approach

Research

How ‘healthy’ do children really need to be? Going beyond the limits

The authors assessed the impact of including preschool‐aged children with a history of preterm birth, early life wheeze, asthma diagnoses and/or recent respiratory symptoms in healthy reference ranges for respiratory impedance using the forced oscillation technique (FOT).

Research

Delayed airway epithelial repair is correlated with airway obstruction in young adults born very preterm

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.
