Can scientists change mucus to make it easier to clear, limiting harm to lungs?
12 Nov 2018 at 4:19pm
For people with conditions such as cystic fibrosis and COPD, mucus can get too thick and sticky; coughing alone can't clear it. Infections develop, leading to severe chronic disease and early death. Now, for the first time, scientists have shown why coughing often cannot tear mucus apart and away from the airway lining. And they showed how to make mucus thinner and less sticky so coughing can become a therapeutic aid.

Outdoor air pollution is a major health threat worldwide. New research found that exposure to certain air pollutants is linked to increased emergency department visits for respiratory and cardiovascular diseases.
Trial finds diet rich in fish helps fight asthma
4 Nov 2018 at 5:51am
A clinical trial has shown eating fish such as salmon, trout and sardines as part of a healthy diet can reduce asthma symptoms in children.
Babies born at home have more diverse, beneficial bacteria, study finds
31 Oct 2018 at 5:05am
Infants born at home have more diverse bacteria in their guts and feces, which may affect their developing immunity and metabolism, according to a new study.
Air pollution leads to millions of ER visits for asthma attacks worldwide
25 Oct 2018 at 5:39am
Nine to 33 million visits to the emergency room (ER) for asthma worldwide may be triggered by breathing in air polluted by ozone or fine particulate matter -- pollutants that can enter the lung's deep airways, according to a new study.
Protein found in patients with severe asthma can help identify who would bene...
22 Oct 2018 at 9:28am
In a novel study, researchers succeeded in identifying patients with a form of severe asthma (type 2 endotype) by measuring periostin concentrations in their airways. These patients with the type 2 (T2) endotype may benefit from newly developed targeted treatments that have the potential to transform their quality of life.
Asthma's effects on airways at the single cell level
18 Oct 2018 at 11:11am
By sequencing genetic material at a cell-by-cell level, researchers have described how type 2-high asthma affects the airways and results in mucus production with more detail than ever before. These findings, which help move forward scientific understanding of the biology behind asthma and could inform the development of targeted treatments for asthma and other airway diseases.
Adding flavors to e-cigarette liquids changes chemistry, creates irritants
18 Oct 2018 at 6:54am
New research shows added flavorings in e-cigarettes or vaping devices react to e-liquid, or e-juice, creating new compounds that could trigger irritation and inflammation when inhaled.
Allergy research: Test predicts outcome of hay fever therapies
18 Oct 2018 at 6:53am
Allergen-specific immunotherapy can considerably improve everyday life for allergy sufferers. It is unclear, however, what exactly happens during this treatment. A team investigated the processes taking place in the body over the course of a three-year allergen-specific immunotherapy. The researchers found clues as to why the allergy immunization takes so long and how the chances of success can be determined at a very early stage.
Polluted city neighborhoods are bad news for asthmatic children
18 Oct 2018 at 6:50am
Children with asthma who grow up in a New York City neighborhood where air pollution is prevalent need emergency medical treatment more often than asthmatics in less polluted areas.
Study of nearly 41,000 women who almost died giving birth shows who's most at...
10 Oct 2018 at 3:07pm
Tens of thousands of American women each year need emergency treatment to save their lives while they deliver their babies, or immediately after. A new study shows how much their risk of a life-threatening birth depends on their racial and ethnic background, and their underlying health.
New way to eliminate allergen-induced asthma attacks
9 Oct 2018 at 6:15am
Scientists have discovered another way to help asthmatics breathe more easily by targeting treatment at the nervous system. A recent study performed on rats shows the carotid bodies, tiny collections of neurons on each side of the neck, may be responsible for causing lung airway narrowing during an allergen-induced asthma attack.
Asthma may contribute to childhood obesity epidemic
9 Oct 2018 at 4:57am
Toddlers with asthma are more likely to become obese children, according to the biggest study on the matter to date.
Have asthma and a pet? Re-homing your cat or dog may not be necessary
4 Oct 2018 at 8:26am
A study analyzed environmental exposures, like pet and secondhand smoke, to determine if they have a role in asthma control among children whose asthma is managed per NAEPP (EPR-3) guidelines. Researchers found that once asthma guidelines are followed, environmental exposures to pets or secondhand smoke were not significant factors in overall asthma improvement over time.
Indoor HEPA filters significantly reduce pollution indoors when outside air u...
25 Sep 2018 at 8:00am
Outdoor air pollution is a major contributor to indoor air pollution -- but high-efficiency particulate air (HEPA) filters used in the home significantly reduce fine-particulate matter in the air compared with non-HEPA air filters, according to a new study.
