New yardstick offers diagnostic and treatment guidance for idiopathic anaphyl...

The new 'Idiopathic Anaphylaxis Yardstick' will help physicians who might be searching for guidance on next steps after their patient has an anaphylactic reaction of an unknown origin.
Childhood behavior linked to taking paracetamol in pregnancy
16 Sep 2019 at 5:14am
A new study adds to evidence that links potential adverse effects of taking paracetamol (also known as acetaminophen) during pregnancy.
Presence of fungal DNA in the fetal human gut
5 Sep 2019 at 11:54am
A recent human study has discovered the presence of fungal communities in the fetal gut. The study marks the first of its kind to observe fungal DNA in this developmental setting.
Genetics may play a role in reaction to CT contrast agents
3 Sep 2019 at 7:15am
Researchers have found that patients with family and personal history of allergic reactions to contrast media are at risk for future reactions, according to a new large study. Allergic reactions to commonly used CT contrast media may be prevented by premedicating patients with antihistamines and using a different type of contrast agent.
Identification of new populations of immune cells in the lungs
3 Sep 2019 at 7:14am
Two very distinct sub-populations of interstitial macrophages exist, and identifies their local precursors. This new knowledge is a further step towards understanding the regulation of the lung immune system and developing targeted approaches to prevent respiratory diseases, such as asthma.
New ways of developing treatment of chronic inflammation
30 Aug 2019 at 8:28am
Researchers have found a new way to treat the inflammation involved in chronic diseases such as psoriasis, asthma and HIV. A group of transmitter substances (cytokines) in the immune system, the so-called IL-1 family, has been shown to play an important role in many of these diseases by regulating the body's immune responses.
Adults with cerebral palsy about twice as likely to develop non-communicable ...

Adults with cerebral palsy are about twice as likely to develop cardiovascular disease and chronic respiratory disease compared to adults without cerebral palsy, according to a new study.
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.'
