Children whose parents regularly smoke or vape marijuana may experience viral respiratory infections, such as the common cold, more frequently than those whose parents do not smoke, according to a new study.
Antibiotic prescriptions for kids plummet during pandemic
20 Jul 2021 at 8:43am
A new study finds that medications prescribed for children dropped by more than a quarter during the first eight months of the pandemic compared to the previous year, with the steepest declines in infection-related medicines like antibiotics and cough-and-cold drugs.
High respiratory efforts in COVID-19 patients could result in self-inflicted ...
19 Jul 2021 at 8:05am
Some COVID-19 patients who experience acute respiratory failure respond by significantly increasing their respiratory effort -- breathing faster and more deeply. There is concern among some doctors that this level of respiratory effort can lead to further damage to these patients' lungs. Working with intensive care clinicians, engineering researchers have used computational modeling to provide new evidence that high respiratory efforts in COVID-19 patients can produce pressures and strains inside the lung that can result in injury.
Firefighters found to have persistent lung damage from Fort McMurray wildfire
19 Jul 2021 at 8:05am
Firefighters at the center of the battle against the massive Fort McMurray, Alberta wildfire in 2016 have persistent lung damage, according to new findings by a occupational health research team. The firefighters had more than double the risk of developing asthma compared with the general population. They also exhibited a number of changes in lung function tests supportive of an effect on the lungs, including greater lung hyperreactivity and increased thickening of the bronchial wall.
Half of young adults with COVID-19 have persistent symptoms 6 months after, s...

A new paper describes persistent symptoms six months after acute COVID-19, even in young home isolated people. The most common symptoms were loss of smell and/or taste, fatigue, shortness of breath, impaired concentration, and memory problems.
Salton Sea aerosol exposure triggers unique and mysterious pulmonary response
23 Jun 2021 at 6:12am
Communities surrounding the Salton Sea, the inland body of water straddling California's Riverside and Imperial counties, show high rates of asthma due, possibly, to high aerosol dust levels resulting from the sea shrinking over time. Scientists suspect, however, the Salton Sea plays an additional role in pulmonary health. A new study performed on mice has found Salton Sea aerosol turns on nonallergic inflammation genes and may also promote lung inflammation.
Beneficial bacteria can be restored to C-section babies at birth
17 Jun 2021 at 1:36pm
Babies born by Cesarean section don't have the same healthy bacteria as those born vaginally, but a new study finds that these natural bacteria can be restored.
First months decisive for immune system development
17 Jun 2021 at 11:36am
Many diseases caused by a dysregulated immune system, such as allergies, asthma and autoimmunity, can be traced back to events in the first few months after birth. To date, the mechanisms behind the development of the immune system have not been fully understood. Now, researchers show a connection between breast milk, beneficial gut bacteria and the development of the immune system.
COVID-19 reinfection rate less than 1 percent for those with severe illness, ...
15 Jun 2021 at 10:21am
A review of more than 9,000 US patients with severe COVID-19 infection showed less than 1 percent contracted the illness again, with an average reinfection time of 3.5 months after an initial positive test.
Common lung infection in infants has different subtypes with differing asthma...
14 Jun 2021 at 12:39pm
New research indicates that there are four molecular subtypes of bronchiolitis -- the most common lung infection in infants. Children with different subtypes face different risks of later developing asthma.
Asthma medication use and exacerbations
25 May 2021 at 1:09pm
How does the switch to a high-deductible health plan affect children with asthma? A new study suggests that enrollment in a high-deductible health plan (HDHP) may not be associated with changes in asthma medication use or asthma exacerbations when medications are exempt from the deductible.
In utero exposure to tiny air pollution particles is linked to asthma in pres...
21 May 2021 at 6:45am
Women who were highly exposed to ultra-fine particles in air pollution during their pregnancy were more likely to have children who developed asthma, according to a new study. This is the first time asthma has been linked with prenatal exposure to this type of air pollution, which is named for its tiny size and which is not regulated or routinely monitored in the United States.
Triple-drug therapy safely cuts serious asthma flares
19 May 2021 at 10:26am
Researchers have found that the inclusion of a third drug to commonly used dual-drug inhalers can reduce asthma exacerbations and improve control over the disease in children, adolescents, and adults with moderate-to-severe asthma.
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.
