Asthma attacks plummeted among Black and Hispanic/Latinx individuals during t...
6 May 2021 at 11:22am
In a report of data collected as part of a trial in Black and Hispanic/Latinx patients with asthma that began before COVID-19 hit the U.S., researchers found total asthma attacks decreased by greater than 40 percent with the onset of the pandemic.
Defective epithelial barriers linked to two billion chronic diseases
6 May 2021 at 7:53am
Humans are exposed to a variety of toxins and chemicals every day. According to the epithelial barrier hypothesis, exposure to many of these substances damages the epithelium, the thin layer of cells that covers the surface of our skin, lungs and intestine. Defective epithelial barriers have been linked to a rise in almost two billion allergic, autoimmune, neurodegenerative and psychiatric diseases.
New guidelines for schools recommend against food bans
5 May 2021 at 4:50am
Schools and child care centres should train staff on food allergies and have epinephrine available to treat anaphylaxis, but new guidelines do not recommend food bans.
Baby's first stool can help predict risk of developing allergies
29 Apr 2021 at 8:24am
Researchers have shown that the composition of a baby's first feces -- a thick, dark green substance known as meconium -- is associated with whether or not a child will develop allergies within their first year of life. By analyzing meconium samples from 100 infants, they show that the development of a healthy immune system and microbiota may start well before a child is born.
Food allergies, changes to infant gut bacteria linked to method of childbirth...

Researchers have found a causal link between caesarean section birth, low intestinal microbiota and peanut sensitivity in infants, and they report the effect is more pronounced in children of Asian descent than others, in a recently published article.
Overgrowth of gut yeast in newborns may increase asthma risk
20 Apr 2021 at 9:14am
An overgrowth of yeast in the gut within the first few months of life may cause changes to the immune system that increase the risk of asthma later on, shows a new study.
Genetic ancestry versus race can provide specific, targeted insights to predi...
15 Apr 2021 at 11:28am
The complex patterns of genetic ancestry uncovered from genomic data in health care systems can provide valuable insights into both genetic and environmental factors underlying many common and rare diseases -- insights that are far more targeted and specific than those derived from traditional ethnic or racial labels like Hispanic or Black, according to researchers.
Air pollution may affect severity and hospitalization in COVID-19 patients
14 Apr 2021 at 10:17am
Patients who have preexisting respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD) and live in areas with high levels of air pollution have a greater chance of hospitalization if they contract COVID-19, according to new research.
There is no 'one size fits all' approach to treat severe asthma
13 Apr 2021 at 2:07pm
Despite a similar clinical presentation, people with severe asthma have strikingly distinct immune profiles, research shows. These findings can be used to develop new therapeutics and enhance precision medicine approaches to treating these patients.
Scientists identify severe asthma species, show air pollutant as likely contr...
13 Apr 2021 at 5:14am
An epidemiological study has shown that not only is non-Th2 a distinct asthma disease, its likely inducer is early childhood exposure to airborne Benzo[a]pyrene, a byproduct of fossil fuel combustion.
Volcanic pollution return linked to jump in respiratory disease cases
12 Apr 2021 at 5:45am
Respiratory disease increased by almost a quarter after the Holuhraun lava eruption in 2014-2015, one of Iceland's largest volcanic eruptions. Emissions returning in the days immediately following volcanic eruptions impact health and are not factored into responses to the public health threat caused by volcanoes. The study authors recommend government responses take these emissions into account.
Fewer people sought medical help for severe asthma attacks during the COVID-1...
29 Mar 2021 at 5:03pm
Fewer patients with severe attacks were seen by their GP or admitted to hospital during the covid-19 pandemic, and fewer were admitted to hospital for pneumonia, influenza and chronic lung diseases, according to new research.
Release of serotonin from mast cells contribute to airway hyperresposivness i...

In asthma, the airways become hyperresponsive. Researchers have found a new mechanism that contributes to, and explains, airway hyperresponsiveness.
Researchers see need for warnings about long-range wildfire smoke
9 Mar 2021 at 12:38pm
The team believes that evacuation efforts and media coverage of local wildfires may have helped protect residents from adverse health effects of smoke exposure as well as direct impacts of the fires.
Immune cell implicated in development of lung disease following viral infection
9 Mar 2021 at 12:38pm
Scientists have implicated a type of immune cell in the development of chronic lung disease that sometimes is triggered following a respiratory viral infection. The evidence suggests that activation of this immune cell serves as an early switch that, when activated, drives progressive lung diseases, including asthma and chronic obstructive pulmonary disease (COPD).
