There are steps we can take to protect ourselves and our families from air pollution, which has well-documented negative consequences for childhood asthma, birth outcomes, pregnancy risks, cardiovascular health, and other diseases.
Asthma: Researchers discover how exposure to microbes protects against asthma
21 Mar 2017 at 11:53am
The incidence of asthma is increasing steadily. One of the reasons given for this rise is the excessive level of hygiene in our environment. Studies have indeed shown that exposure to a so-called "non-hygienic" environment, rich in microbes, plays a protective role against the development of allergies, including asthma. New research shows that exposure to bacterial DNA drastically amplifies a population of pulmonary macrophages and makes them strongly immunosuppressive, which prevents and treats asthma in mice. This discovery offers promising prospects for the development of a cell therapy based on the administration of these regulatory macrophages to asthmatic patients.
Support people with asthma to manage their illness, researchers say
17 Mar 2017 at 10:12am
Every person with asthma should have access to a personal action plan to help them control their condition, researchers say. Helping people with asthma take control of their own illness reduces symptoms, improves quality of life, reduces emergency use of health services and even prevents deaths, research has shown.
City living can make asthma worse for poor children, study finds
15 Mar 2017 at 6:45am
Results of a new study using US national data add to evidence that living in inner cities can worsen asthma in poor children. They also document persistent racial/ethnic disparities in asthma.
Novel technique helps diagnose swimming-induced respiratory condition
13 Mar 2017 at 10:49am
Exercise-induced obstruction of the larynx, or voice box, is often a cause of respiratory symptoms in athletes and is particularly prevalent in swimmers. A new report reveals a method to accurately diagnose this condition, using a flexible laryngoscope.
'Preventable' asthma attacks in Houston cost millions
13 Mar 2017 at 7:24am
A study shows where and when Houston students with asthma were most likely to suffer attacks that required emergency treatment over a 10-year span. The study suggests how school districts can best help students with asthma.
Breath of fresh air for severe asthma research
10 Mar 2017 at 11:23am
New research points to immunological differences in responses to steroids in patients with severe asthma, suggesting why corticosteroids may paradoxically perpetuate inflammation in severe asthma.
Mite-proof bedcovers may reduce asthma flare-ups in children
10 Mar 2017 at 6:21am
Bedcovers that form a barrier to house dust mites appear to reduce asthma flare-ups in children, according to new research.
Asthmatics less able to fight off flu
9 Mar 2017 at 9:04am
People with asthma are likely to have worse symptoms when they get the flu because they have weaker immune systems, new research has shown.
Women suffer from asthma symptoms more frequently and more severely than men
7 Mar 2017 at 6:13am
Women suffer more frequently and more severely from pollen and food allergies and therefore also from asthma. Firstly, female sex hormones increase the risk and symptoms of asthma and allergies and, secondly, hormone preparations such as the contraceptive pill play a role.
Mouse arrest: Professional pest management no more effective than do-it-yours...
6 Mar 2017 at 8:00am
A professional pest management intervention was no better in decreasing asthma symptoms in children allergic to mice than teaching families how to reduce the level of allergens shed by mice in the home on their own, a new study has concluded.
New technique removes the cause of allergic asthma: Antibodies are suctioned off
3 Mar 2017 at 6:15am
Allergies are the most common cause of asthma. The immune system over-reacts to harmless substances such as birch or grass pollen, for example, forming immunoglobulin E antibodies (IgE). Together with the inflammatory cells in the skin and mucous membranes, the "mast cells", IgE antibodies are responsible for certain allergic diseases, such as asthma and hay fever. Scientists have now successfully developed a technique for suctioning the IgE antibodies out of the blood, thereby significantly improving the quality of life for people who suffer from severe allergic asthma.
Racial gap in children's asthma linked to social inequality
1 Mar 2017 at 7:54am
African-American and poor children in the United States suffer disproportionately from asthma. But according to a new study, racial and socio-economic gaps in the proportion of children in Houston who have asthma may be a result of social inequalities in the neighborhoods where children live.
Study brings hope of a new treatment for asthma sufferers
1 Mar 2017 at 6:25am
Improved treatments for people with severe asthma are a ?step closer? after a research team identified a breakthrough in the cause of airway narrowing.
Inhaler users get about half as much medicine as they should from each puff
28 Feb 2017 at 10:11am
Tens of millions of Americans use aerosol inhalers each day, and new studies by electrical engineers and pulmonologists have identified critical errors that are causing many inhaler users to get only about half as much medicine as they should from each puff.
