Critical errors in inhaler technique common in children with asthma
17 Apr 2019 at 12:37pm
In the first study to evaluate inhaler technique in children hospitalized for asthma -- the group at highest risk for complications and death from asthma -- researchers found that nearly half of participants demonstrated improper inhaler use, which means they routinely were not taking in the full dose of medication. Adolescents most commonly displayed critical errors in inhaler technique.
Large multi-ethnic genome-wide association study of asthma identifies novel a...

A large, multi-ethnic genome-wide association study (GWAS) of asthma identified novel associations with potential relevance for asthma susceptibility in older adults of diverse racial backgrounds.
Diesel exhaust filtered of its tiny particles may worsen allergy-induced lung...

Air pollution from diesel engines may worsen allergy-induced lung impairment more when tiny particles are filtered from the exhaust than when they are not, according to new research published online in the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.
Millions of children worldwide develop asthma annually due to traffic-related...
10 Apr 2019 at 6:00pm
About 4 million children worldwide develop asthma each year because of inhaling nitrogen dioxide air pollution, according to a new study. The study, based on data from 2010 to 2015, estimates that 64 percent of these new cases of asthma occur in urban areas.
Identifying the grass pollen that gets up your nose
8 Apr 2019 at 8:42am
Scientists could be a step closer to providing more precise pollen forecasts to people who live with asthma or hay fever. This follows the first results of a major three-year project to analyze airborne grass pollen. For the first time, one season's grass pollens have been analyzed using high-tech metabarcoding. The team have now begun investigating links between certain pollen types and those days when plant allergy sufferers and people with asthma are most affected.
Study links insurance coverage to access to hospital care
1 Apr 2019 at 8:58am
Compared to privately insured patients, individuals who lack insurance or use Medicaid are more likely to be transferred to another hospital after receiving initial treatment in the emergency department (ED). The uninsured are also at greater risk of being discharged from an ED and not admitted to the hospital.
Sugar could be sweet solution to respiratory disease
1 Apr 2019 at 8:57am
Restriction or inhalation of common sugar could one day treat a range of respiratory diseases, according to new research. The study in mice reveals how the ability of cells to use glucose helps to regulate the immune system during lung inflammation. Their research suggests that blocking sugar receptors in the lung could reduce inflammation in chronic conditions such as asthma, allergies and parasitic worm infections.
Omega-3 and omega-6 fatty acids may play opposite roles in childhood asthma
29 Mar 2019 at 4:59am
Dietary intake of two fatty acids, omega-3 and omega-6, may have opposite effects on the severity of asthma in children and may also play opposite roles in modifying their response to indoor air pollution, according to new research.
A bad bout of flu triggers 'taste bud cells' to grow in the lungs
28 Mar 2019 at 12:09pm
When researchers examined mice that had recovered from severe influenza, they came upon a surprising discovery: Taste bud cells had grown in the animals' lungs. The team believes the cells may play a role in immunity.
Adipose hormone may play role in obesity-related asthma
25 Mar 2019 at 5:04am
New research suggests a hormone released from fat tissue is critical in the development of obesity-related asthma and may be a target of future treatments for the disease.
Exposure to HIV virus, treatment before birth linked to obesity later in life
25 Mar 2019 at 5:04am
Teens and young adults who were exposed to HIV and antiretroviral therapy before birth but are HIV-negative themselves are at increased risk of obesity and asthma-like symptoms.
Eating fish may help prevent asthma
19 Mar 2019 at 7:07am
An innovative study has revealed new evidence that eating fish can help prevent asthma.
Determining what binds to mucus
13 Mar 2019 at 8:47am
The human body is full of mucus. This viscous goo isn't just a nuisance that gets coughed up or sneezed out -- it can bind to drugs, toxins or microbes, potentially impacting human health. However, relatively little is known about such interactions. Now, researchers say they have developed a new way of analyzing mucus binding that could lead to better drug development.
Academic performance of urban children with asthma worse than peers without a...
11 Mar 2019 at 5:19am
A new study shows urban children with poorly controlled asthma, particularly those who are ethnic minorities, also suffer academically. Kids who were kept home due to asthma symptoms weren't able to do as well in the classroom.
