Normal values of respiratory oscillometry in South African children and adolescentsNoninvasive measurement of respiratory impedance by oscillometry can be used in young children aged from 3 years and those unable to perform forced respiratory manoeuvres. It can discriminate between healthy children and those with respiratory disease. However, its clinical application is limited by the lack of reference data for African paediatric populations. The aim of the present study was to develop reference equations for oscillometry outcomes in South African children and adolescents.

Lung inflammation and simulated airway resistance in infants with cystic fibrosisCystic fibrosis (CF) is characterized by small airway disease; but central airways may also be affected. We hypothesized that airway resistance estimated from computational fluid dynamic (CFD) methodology in infants with CF was higher than controls and that early airway inflammation in infants with CF is associated with airway resistance.

Systems biology and bile acid signalling in microbiome-host interactions in the cystic fibrosis lungThe study of the respiratory microbiota has revealed that the lungs of healthy and diseased individuals harbour distinct microbial communities. Imbalances in these communities can contribute to the pathogenesis of lung disease. How these imbalances occur and establish is largely unknown. This review is focused on the genetically inherited condition of Cystic Fibrosis.

BAL Inflammatory Markers Can Predict Pulmonary Exacerbations in Children With Cystic FibrosisPulmonary exacerbations in cystic fibrosis are characterized by airway inflammation and may cause irreversible lung damage. Early identification of such exacerbations may facilitate early initiation of treatment, thereby potentially reducing long-term morbidity. Research question: Is it possible to predict pulmonary exacerbations in children with cystic fibrosis, using inflammatory markers obtained from BAL fluid?

Microbiomic Analysis on Low Abundant Respiratory Biomass Samples; Improved Recovery of Microbial DNA From Bronchoalveolar Lavage FluidIn recent years the study of the commensal microbiota is driving a remarkable paradigm shift in our understanding of human physiology. However, intrinsic technical difficulties associated with investigating the Microbiomics of some body niches are hampering the development of new knowledge. This is particularly the case when investigating the functional role played by the human microbiota in modulating the physiology of key organ systems. A major hurdle in investigating specific Microbiome communities is linked to low bacterial density and susceptibility to bias caused by environmental contamination.
