Researchers also identify occupational exposure to insecticides and moldy environments...
A recent survey found that asthma control in US children falls short of national treatment goals, with most experiencing frequent symptoms and missed school days. The study highlights the need for better communication between parents and children to effectively manage the condition.
A new study reveals that patients with asthma experiencing high variability in disease symptoms incur greater direct and indirect costs, including hospitalizations, emergency visits, and lost productivity. High variability patients also report more frequent unscheduled doctor visits and asthma interrupts daily activities more often.
A study of children with asthma in Denver found that winter air pollution had no significant effect on asthma exacerbations or lung function. However, upper respiratory infections more than quadrupled the odds of an asthma exacerbation and increased symptoms.
The ERICCA project aims to integrate electronic health records to improve asthma care for children. The system will facilitate communication among care providers, allow inter-disciplinary care planning, and provide clinical decision support.

Additionally, a study identified unique tumor signatures that can predict lung cancer death within 12 months with an accuracy rate of 87%.
Researchers discovered a link between respiratory syncytial virus (RSV) and asthma in mice, showing that an anti-RSV antibody could decrease the risk of developing asthma. The study suggests that treatments against RSV may reduce asthma-related complications in children.
A meta-analysis of 33 trials found that continuous use of asthma drugs increases airway inflammation and decreases bronchodilator response, while also posing cardiac risks for patients with chronic obstructive lung disease. 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.
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 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.
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 study of 10,440 single-born infants found no increased risk of hospitalization for asthma among children born to mothers who consumed alcohol during pregnancy. Despite this, researchers caution that high prenatal alcohol exposure may still have unknown health effects.
A nationwide sample of children with asthma found that 13% of parents still smoke, triggering year-round symptoms. Pediatricians should counsel parents on quitting to improve their children's health.
The study found that school-based provision of inhaled corticosteroids resulted in fewer missed days of school and more symptom-free days for urban children. However, the program had limited effectiveness among those exposed to secondhand smoke in their homes.
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.
Postmenopausal hormone therapy has been associated with an increased risk of developing asthma in women, according to a study published in the Archives of Internal Medicine. Researchers found that current use of estrogen alone was linked to a 2.29 times higher risk of new asthma diagnoses compared to non-hormone users.
A study of influenza vaccination in children with asthma found no significant reduction in asthma exacerbations caused by the flu. In contrast, a separate study showed that maternal and personal smoking synergize to increase airflow limitation in offspring, increasing the risk of Chronic Obstruction Pulmonary Disease (COPD).
Researchers at OHSU are conducting a study to investigate whether early treatment with the eczema drug Elidel can prevent asthma in children with a family history of allergic disease. The study aims to enroll 200 infants with eczema and assess whether early intervention reduces the incidence of asthma.
A recent study found that children who experienced fewer fevers in their first year were less likely to develop allergies by age 6. Researchers discovered that fever-inducing infections involving the eyes, ears, nose, or throat appeared to be associated with a lower risk of developing allergies.
Antioxidants beta-carotene and vitamin C, as well as selenium, were associated with lower asthma prevalence in US youth under age 17. In contrast, continuous positive airway pressure therapy improved systolic heart function and reduced symptoms in patients with congestive heart failure and sleep apnea.
A recent study published in The Lancet found that doubling the dose of inhaled corticosteroid before a severe asthma attack does not provide additional benefits. The research involved 390 patients who monitored their asthma for up to one year and received either an extra inhaler or placebo when control deteriorated.
