Critical care use was common among seriously ill patie...
Resveratrol exhibited anti-inflammatory activity in all systems examined, including laboratory cell lines and human airway epithelial cells. The compound inhibited the release of inflammatory mediators, including IL-8 and GM-CSF, which play a major role in inflammation development.
The BARGE trial found that individuals with the arginine genotype had poorer asthma control when using albuterol, while those with the glycine genotype had better asthma control. This suggests that genetic variations can impact response to common asthma medication, leading to potential personalization of therapy.

The studies suggested that pharmaceutical company sponsorship may be a factor in the conflicting results.
Asthma researchers at Yale discovered a new protein, AMCase, that contributes to inflammation in the airways. Blocking this protein may provide relief for humans with asthma, but its mechanism of action is not yet fully understood.
A recent study by Cohn et al. found that 82 percent of U.S. homes contain mouse allergens, with kitchen floors being the most contaminated area. The study, conducted across the entire country, highlights the need for clinicians to consider rodent and cockroach problems as risk factors when treating allergy and asthma patients.
Researchers found that Puerto Rican children with parents reporting asthma were more likely to have depressive disorders. Children experiencing asthma attacks were also at higher risk for anxiety disorders, including separation anxiety.
A study of 338 Chicago neighborhoods found that areas with low collective efficacy had higher asthma rates due to lack of trust, poor air quality, and limited access to health services. Neighborhoods with high collective efficacy, on the other hand, had lower asthma rates due to stronger social connections.
Researchers found that antibiotic therapy can promote allergic airway responses in mice, particularly when Candida albicans colonization occurs. The study suggests a potential link between antibiotic use and human allergies.

A recent study suggests that mycoplasma bacterial infections may cause or exacerbate asthma attacks in children. The research found that nearly half of children experiencing their first asthma attack were infected with mycoplasma. Testing for mycoplasma infection in asthmatic children could help prevent future attacks.
A study found that almost one-fifth of asthma parents believe exercise is dangerous for their children, leading to lower physical activity levels. Children with moderate or severe asthma are also less likely to engage in high levels of physical activity due to parental misconceptions.
A study suggests that viral infections like RSV can increase the expression of Toll-4 receptors on airway cells, leading to a heightened response to endotoxin exposure and potentially causing asthma exacerbations. This increased sensitivity could also make airways more responsive to other environmental exposures.
Researchers found that long-term albuterol use can lead to accumulation of the (S)-isomer, which reduces anti-inflammatory effects and worsens asthma symptoms. The study suggests that current combination therapies may not be realizing their full potential due to isomer interactions.
A study of 740 homeless children in NYC found that 26.9% had a prior diagnosis of asthma and 12.9% reported symptoms consistent with moderate or severe persistent asthma. The authors suggest that high levels of exposure to adverse psychological factors contribute to the severity and undertreatment of asthma in homeless children.

Researchers report success with new anti-IL-5 therapy in treating severe forms of hypereosinophilic syndrome, reducing eosinophil counts and improving symptoms. The treatment has been well-tolerated and improved the quality of life for all four patients, including one who regained ability to eat solid foods after years of inability.
Children under 18 were more than twice as likely to be harmed in placebo-controlled trials due to asthma exacerbations compared to those receiving standard asthma therapy. Established guidelines recommend anti-inflammatory medications for all children and adults with mild-persistent, moderate or severe asthma.
