Asthma and hay fever linked to increased risk of psychiatric disorders
23 Apr 2018 at 5:54am
A new study is the first to find a significant link between asthma, hay fever and a broad spectrum of psychiatric disorders. Over 15 years, 10.8 percent of patients with allergic diseases developed a psychiatric disorder, compared to only 6.7 percent of those without allergies. Monitoring the mental health of patients with allergies could help doctors care for their patients more effectively.
Why don't kids use their asthma medicines?
18 Apr 2018 at 6:20am
In a new analysis of interviews conducted with children who have asthma, their caregivers and their clinicians, researchers found that there was significant lack of agreement about why the kids miss their needed daily anti-inflammatory medication.
Three-quarters of COPD cases are linked to childhood risk factors that are ex...

Three-quarters of chronic obstructive pulmonary disease (COPD) cases have their origins in poor lung function pathways beginning in childhood. These pathways are associated with exposures in childhood, and amplified by factors in adulthood, according to a cohort study. While smoking remains the biggest risk factor for COPD, the study demonstrates that childhood illnesses (such as asthma, bronchitis, pneumonia, allergic rhinitis, eczema) and exposures to parental smoking are also linked to the disease.
X-linked genes help explain why boys of all ages face higher respiratory risk
5 Apr 2018 at 12:55pm
Human airways already demonstrate gender-based differences in DNA methylation signatures at birth, providing an early hint of infants who may be predisposed to develop respiratory disorders later in life.
Up to 38 percent of all annual childhood asthma cases in Bradford, U.K. may ...

New research highlights the impact of traffic-related air pollution on childhood asthma. The study also shows traffic-related air pollution could be specifically responsible for up to 24 percent of the total number of cases. An international team of researchers has used a newly developed model to assess the impact exposure to nitrogen oxides -- gases that make up air pollution -- has on the development of childhood asthma.
Pregnant women and new moms still hesitant to introduce peanut products
19 Mar 2018 at 12:57pm
In January 2017 guidelines were released urging parents to begin early introduction of peanut-containing foods to reduce the risk of peanut allergy. A new study shows those who are aware of the guidelines are still hesitant to put them into place and not everyone has heard of them.
Quintupling inhaler medication may not prevent asthma attacks in children
19 Mar 2018 at 11:45am
Children with mild to moderate asthma do not benefit from a common practice of increasing their inhaled steroids at the first signs of an asthma exacerbation, according to clinical trial results. Researchers found short-term increases in inhaled steroids did not prevent attacks in children aged 5 to 11, and may even slow a child's growth.
Genetic variant discovery to help asthma sufferers
16 Mar 2018 at 12:38pm
Researchers have identified a genetic variant that could improve the safety and effectiveness of corticosteroids, drugs that are used to treat a range of common and rare conditions including asthma, and chronic obstructive pulmonary disease (COPD).
Common biological features of different types of asthma identified
14 Mar 2018 at 8:09am
A team of researchers has identified biological variations in lung tissue samples that for the first time can help identify people with mild asthma from those with moderate or severe asthma.
Mesenchymal stem cell therapy: Holding promise for feline inflammatory diseases
13 Mar 2018 at 8:35am
Stem cell therapy is acknowledged as having great potential for the treatment of a variety of diseases in both people and animals. The use of bone marrow-derived stem cells is well established in the treatment of human cancer patients, and veterinary applications for bone marrow- and adipose-derived stem cells are being evaluated.
An itch you can't scratch: Researchers find 'itch receptors' in the throats o...
9 Mar 2018 at 6:54am
Working with mice, researchers report they have found previously known skin itch receptors in the airways that appear to contribute to bronchoconstriction and airway hypersensitivity, hallmarks of asthma and other respiratory disorders. The investigators' experiments in mice suggest that the receptors' activation directly aggravates airway constriction and -- if the same process is active in people -- may be a promising new target for the development of drug therapies.
Serious asthma attacks reduced by temporary quadrupling of steroid inhaler, s...
8 Mar 2018 at 7:52am
Serious asthma attacks in adults can be reduced by a temporary but significant increase in the dose of inhaled steroids during severe episodes of asthma, according to a new study.
New molecular target could help ease asthma
7 Mar 2018 at 11:13am
Researchers have shown that the protein vascular endothelial growth factor A -- or VEGFA -- plays a major role in the inflammation and airway obstruction associated with asthma. The finding may eventually lead to new asthma treatments targeting VEGFA.
Environmental exposures more determinant of respiratory health than inherited...
6 Mar 2018 at 8:54am
Researchers have found strong evidence that environmental exposures, including air pollution, affect gene expressions associated with respiratory diseases much more than genetic ancestry. The study analyzed more than 1.6 million data points from biological specimens, health questionnaires and environmental datasets, making this study one of the largest ever to examine the relationship between gene expression and environmental stimuli.
Mothers who smoke while pregnant contribute to the severity of asthma and poo...

Tobacco smoke exposure during pregnancy is worse for children with asthma than postnatal secondhand smoke exposure, according to a new study in the journal.
