Early nasal microbiota and subsequent respiratory tract infections in infants with cystic fibrosis

Respiratory tract infections (RTIs) drive lung function decline in children with cystic fibrosis (CF). While the respiratory microbiota is clearly associated with RTI pathogenesis in infants without CF, data on infants with CF is scarce. We compared nasal microbiota development between infants with CF and controls and assessed associations between early-life nasal microbiota, RTIs, and antibiotic treatment in infants with CF. 

New trial aims to nip chronic lung disease in the bud for First Nations kids

WA researchers will use a $1.97 million Medical Research Future Fund grant to develop a strategy for better follow-up of First Nations children after they’ve been hospitalised for respiratory infections, in a bid to halt the slide into more severe lung disease.

Airway macrophages display decreased expression of receptors mediating and regulating scavenging in early cystic fibrosis lung disease

Cystic fibrosis (CF) airway disease is characterized by chronic inflammation, featuring neutrophil influx to the lumen. Airway macrophages (AMs) can promote both inflammation and resolution, and are thus critical to maintaining and restoring homeostasis. CF AM functions, specifically scavenging activity and resolution of inflammation, have been shown to be impaired, yet underlying processes remain unknown.

Smoking during pregnancy, vitamin C supplementation, and infant respiratory health

This article discusses the merits and potential shortcomings of a study reported previously showing that giving Vitamin C to women who smoked during...

Persistent Effects of Maternal Smoking during Pregnancy on Lung Function and Asthma in Adolescents

The extent to which maternal smoking in pregnancy (MSP) has persisting effects on respiratory health remains uncertain and the mechanisms involved are not...

FINGERPRINT: FINdinG Early markers of Respiratory disease for survivors of PReterm birth which IdeNtify Treatable traits

This research project will investigate the traits of preterm lung disease, looking into the long-term lung health of children born preterm, aiming to identify traits that could help guide better treatments in the future.

House dust mite induced lung inflammation does not alter circulating vitamin D levels

We hypothesized that allergic inflammation decreases the level of circulating 25(OH)D and tested this using a mice model of house dust mite (HDM) induced...

Sexual dimorphism in lung function responses to acute influenza A infection

Males are generally more susceptible to respiratory infections; however, there are few data on the physiological responses to such infections in males and...

Rhinovirus exacerbates house-dust-mite induced lung disease in adult mice

In this study, we combined human-rhinovirus infection with a clinically relevant mouse model of aero-allergen exposure using house-dust-mite in an attempt to...

The effects of in utero vitamin D deficiency on airway smooth muscle mass and lung function

In this study, we aimed to uncover the molecular mechanisms contributing to altered lung structure and function.
