Inhalation therapy shows promise against pulmonary fibrosis in mice, rats

A new study shows that lung stem cell secretions — specifically exosomes and secretomes — delivered via nebulizer, can help repair lung injuries due to multiple types of pulmonary fibrosis in mice and rats.

Differences in airway size develop during puberty

Sex differences in airway size are not innate, but likely develop because of hormonal changes around puberty, reports a new study.

New hope for COPD patients possible with in-home device

Researchers describe the benefits of in-home noninvasive ventilation therapy, which includes a type referred to as bilevel positive airway pressure, or BiPAP — for many patients with chronic obstructive pulmonary disease (COPD). The team identified a number of benefits, including reduced mortality, fewer hospital…

Cancer drugs could potentially treat COPD

New research has shown the potential for clinically available cancer treatments to treat chronic obstructive pulmonary disease (COPD).

Crimped or straight? Lung fiber shape influences elasticity

Stiff collagen and stretchy elastin fibers packed together in rows allow the respiratory system to stretch and snap back into shape. Scientists previously thought these fibers govern the mechanics of the airways due to their composition. New research has instead observed that differences in…

Obesity exacerbates many causes of death, but risks are different for men and women

People who carry around unhealthy amounts of weight don’t just have heart disease and diabetes to worry about. Obesity is implicated in two thirds of the leading causes of death from non-communicable diseases worldwide and the risk of certain diseases differs for men and…

Ex-smokers, light smokers not exempt from lung damage

A new study shows that smoking even a few cigarettes a day is harmful to lungs and that former smokers continue to lose lung function at a faster rate than never-smokers for decades after quitting.

Nanoparticles wiggling through mucus may predict severe COPD

In a proof-of-concept experiment, researchers say they have successfully used microscopic human-made particles to predict the severity of patients’ chronic obstructive pulmonary disease (COPD) by measuring how quickly the particles move through mucus samples. The technique, say the researchers, could eventually help doctors deliver…

Older adults with COPD more likely to use synthetic cannabinoids

Chronic obstructive pulmonary disease (COPD) is a progressive lung disease that’s often associated with a variety of health problems, including chronic muscle pain and insomnia. Psychoactive drug classes, like cannabinoids, are often prescribed to help reduce pain, promote sleep and decrease breathlessness. A study…

E-cigs can trigger same lung changes seen in smokers, emphysema

Scientists found that the lungs of vapers — like the lungs of smokers — have elevated levels of protease enzymes, a condition known to cause emphysema in smokers. The researchers also found that the nicotine in vaping liquids is responsible for the increase in…
