Children with mild asthma can use inhalers as needed, study suggests
16 Aug 2019 at 4:14pm
A new study supports evidence that children with mild asthma can effectively manage the condition by using their two inhalers -- one a steroid and the other a bronchodilator -- when symptoms occur. This is in contrast to the traditional method of using the steroid daily, regardless of symptoms, and the bronchodilator when symptoms occur. The as-needed use of both inhalers is just as effective for mild asthma as the traditional protocol, according to the investigators.
Multiple genes affect risk of asthma, hay fever and eczema
5 Aug 2019 at 7:11am
Researchers have found a total of 141 regions (genes) in our genetic material that largely explain the genetic risk underlying asthma, hay fever and eczema. As many as 41 of the genes identified have not previously been linked to an elevated risk for these diseases. The results are published in the scientific journal Human Molecular Genetics.
Scientists discover immune cell subtype in mice that drives allergic reactions
1 Aug 2019 at 11:25am
Allergies can be life-threatening when they cause anaphylaxis, an extreme reaction with constriction of the airways and a sudden drop in blood pressure. Scientists have identified a subtype of immune cell that drives the production of antibodies associated with anaphylaxis and other allergic reactions. The research reveals a potential target for new therapies to prevent severe allergic reactions.
Lung cell patches its own DNA on the fly to survive influenza
29 Jul 2019 at 11:49am
Scientists have identified one kind of lung cell that can hustle to repair its damaged DNA and survive an attack of the influenza A virus while other kinds of cells around it die in droves. The finding reveals more about the battle between cells and viruses at the smallest level, and also may provide some important clues for respiratory conditions such as chronic obstructive pulmonary disease and asthma.
Airborne particles can send our detox systems into overdrive
25 Jul 2019 at 7:29am
As the world gets more and more industrialized, the risk of developing respiratory diseases increases. Very small particles released from industry and vehicle fumes are harmful to our health but exactly how is still unclear. Researchers have now uncovered one mechanism that can exaggerate inflammation in response to diesel fumes and worsen symptoms of respiratory diseases.
Ozone threat from climate change
23 Jul 2019 at 9:19am
We know the recent extreme heat is something that we can expect more of as a result of increasing temperatures due to climate change. But a new study warns that there's another impact -- worsened air quality due to an increase in the number and intensity of 'ozone alert' days.
Strong family relationships may help with asthma outcomes for children
18 Jul 2019 at 8:24am
Positive family relationships might help youth to maintain good asthma management behaviors even in the face of difficult neighborhood conditions, according to a new study.
Cracks in the skin of eczema patients promote allergic diseases
17 Jul 2019 at 8:03pm
Many babies with eczema go on to develop food allergies, asthma and hay fever, and researchers say it's not a coincidence. The cracks caused by eczema weaken the skin barrier, allowing allergens to penetrate the skin and cause a sequence of allergic diseases, what experts call the 'atopic march.'
Health insurance idea could help millions of Americans spend less
17 Jul 2019 at 11:26am
New federal rule could reduce out-of-pocket costs for key drugs and services for people with chronic conditions in high-deductible health plans with health savings accounts.
No link between flu vaccine in pregnancy and later health problems in children
10 Jul 2019 at 4:39pm
There is no association between exposure to the 2009 H1N1 'swine flu' vaccine during pregnancy and health problems in early childhood, concludes a new study.
'Chaos' in the home linked to poor asthma control in children
9 Jul 2019 at 11:12am
A chaotic household, as well as child and parent depression, are risk factors for worse asthma outcomes in urban minority children, according to a new article.
Integrated, multi-'omic' studies of asthma could lead to precision treatment
2 Jul 2019 at 8:28am
Carefully designed, integrated multi-'omic' studies could accelerate the use of precision medicine for asthma patients, according to researchers.
'Back to school asthma' linked to tripling in rate of health service appointm...
1 Jul 2019 at 3:46pm
'Back to school asthma' -- a seasonal peak in cases associated with the start of the school year in September -- is linked to a tripling in the rate of family doctor (GP) appointments across England.
New knowledge on the development of asthma
26 Jun 2019 at 1:03pm
Researchers have studied which genes are expressed in overactive immune cells in mice with asthma-like inflammation of the airways. Their results suggest that the synthesis and breakdown of fats plays an important part in the process.
Good physical fitness in middle age linked to lower chronic lung disease risk
18 Jun 2019 at 4:20pm
Good heart and lung (cardiorespiratory) fitness in middle age is associated with a lower long term risk of chronic lung disease (COPD), suggests new research.
