Maternal marijuana use linked to low birth weight
27 Apr 2017 at 8:22am
Researchers found that women who used marijuana while pregnant were almost three times more likely to have an infant with low birth weight. It is the first large-scale study in Canada to show this association between maternal marijuana use and low birth weight infants.
Inhaled steroids may increase pneumonia risk in people with asthma
20 Apr 2017 at 6:02am
Use of inhaled corticosteroids was linked with an increased risk of pneumonia in a study of individuals with asthma, say researchers.
Study defines thunderstorm asthma epidemic conditions
19 Apr 2017 at 8:24am
Researchers are exploring new ways of predicting thunderstorm asthma outbreaks that may one day provide early warnings for health professionals.
Experimental drug targets nucleus of allergen-sensitized cells
18 Apr 2017 at 12:13pm
Transcription factors, the tiny proteins that switch genes on or off in the nucleus of cells, are considered unreachable molecular targets for drugs attempting to treat medical conditions. Overcoming this challenge, researchers discovered a small molecular compound that successfully blocks a transcription factor and its pro-inflammatory and hyper-mucous activity in asthma. In a study, scientists tested a new compound they call RCM-1.
Air pollution may directly cause those year-round runny noses, according to a...
18 Apr 2017 at 6:43am
Although human population studies have linked air pollution to chronic inflammation of nasal and sinus tissues, direct biological and molecular evidence for cause and effect has been scant. Now, researchers report that experiments in mice continually exposed to dirty air have revealed that direct biological effect.
Doctors develop novel flu test to speed up respiratory treatment
6 Apr 2017 at 12:24pm
Doctors and researchers have developed a novel way of using a swab test which can rapidly diagnose flu and other viral infections in patients with severe respiratory conditions - resulting in shorter courses of antibiotics and less time in hospital.
Kids' hands may be a source of significant nicotine exposure
6 Apr 2017 at 7:57am
Children may carry significant levels of nicotine on their hands just by coming into contact with items or surfaces contaminated with tobacco smoke residues, even when no one is actively smoking around them at the time. A new study also reports the presence of significant nicotine on the hands of children was associated with equally significant levels of the harmful tobacco metabolite cotinine in saliva.
Early life antibiotic use linked to inflammatory gut diseases in adulthood
3 Apr 2017 at 9:33am
A new research report involving mice shows that antibiotic use very early in life that alters the normal development/growth of gut bacteria, may contribute to the development of inflammatory bowel disease, and potentially other inflammatory diseases like asthma and multiple sclerosis.
Novel method for generating airway cells from stem cells
30 Mar 2017 at 11:23am
Researchers have developed a new approach for growing and studying cells they hope one day will lead to curing lung diseases such as cystic fibrosis through 'personalized medicine.'
High-fat diet during pregnancy compromises offspring's lung health
29 Mar 2017 at 7:37am
Women who follow a high-fat diet during pregnancy may increase their children?s risk for asthma. A mouse study suggests that consistent consumption of fat-laden foods may change the immune response of the offsprings? respiratory system.
Asthmatic schoolchildren are 'uncomfortable' using their inhalers
29 Mar 2017 at 7:24am
Poor asthma control and knowledge are common in children with doctor-diagnosed asthma, according to new research.
Are tree nut allergies diagnosed too often?
27 Mar 2017 at 5:31am
About 50 percent of those who thought they were allergic to all tree nuts were able to pass an oral food challenge without a reaction, new research shows.
When air pollution is bad, know how to protect yourself
23 Mar 2017 at 5:41am
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.
