Purpose: Tracheal occlusion (TO) reverses pulmonary hypoplasia (PH) in congenital diaphragmatic hernia (CDH), but its effect on epithelial-mesenchymal transition (EMT) in lung development remains poorly understood. The purpose of this study was to a) confirm the CDH rabbit model produced PH which was reversed by TO and b) determine the effects of CDH +/- TO on EMT pathways.
Methods: CDH was created at 23 days, TO at 28 days and lung collection at 31 days gestation in fetal rabbits. Lung body weight ratio (LBWR), mean terminal bronchiole density (MTBD), and expression of mRNA and micro-RNA was determined.
Results: Fifteen CDH, …

Chronic obstructive lung disease (COPD), develops gradually, and tends to be noticed by farmers only after there has been a significant loss of lung function. People with symptoms of COPD often present for health care in later stages of disease, because they accept cough or breathlessness as “normal”.
Measurement of lung health for those at risk of developing COPD provides an opportunity for early detection of lung disease, and deter the progression toward irreversible damage to the lungs. COPD is, however, under-diagnosed.
The importance of bringing primary care providers and farmers together, and acknowledging the high-risk nature of occupational exposures, …
