A new study supports a University of Houston professor's theory that blocking the beta-2 adrenoreceptor receptor instead of stimulating it could be a safer and more effective strategy for long-term asthma management. The research, published in PNAS, reveals that a mouse model without the key gene produces fewer asthma-like symptoms.
A new treatment has been shown to reduce the severity and duration of asthma attacks triggered by colds in preschoolers. The study found a 50% decrease in asthma attacks requiring oral steroids and a 20% reduction in illness duration, improving symptoms and quality of life.
A recent study found that daily nitric oxide monitoring did not significantly improve treatment outcomes for children with mild to moderate asthma. Despite a reduction in medication dose, both groups showed an impressive overall improvement in symptoms.

A recent Mayo Clinic study found adults with asthma are seven times more likely to develop invasive pneumococcal diseases, a serious and potentially fatal condition. The researchers recommend including asthma as an indication for pneumococcal vaccination in adults, which could significantly reduce instances of this disease.
A Kansas State University graduate student has found a correlation between childhood obesity and asthma. Healthy children with higher body fat levels and lower physical activity had greater airway narrowing after exercise, suggesting an early link to asthma diagnosis.
A new study concludes that long-acting beta2-agonists (LABAs) offer no additional benefit to conventional preventative medications in children. LABAs, such as salmeterol and formoterol, can improve lung function but do not reduce asthma symptoms or hospital admissions.

These studies suggest that these alternatives may be more effective and less expensive than traditional treatments.
Asthma affects over 2 million Australians, with a plateauing prevalence among children and declining hospital admission rates since 1993. Despite positive trends, asthma remains a major concern due to smoking habits, lack of written action plans, and higher mortality rates among Indigenous Australians.
High levels of nitrogen dioxide from stoves can aggravate asthma symptoms in inner-city preschoolers, according to a new study by Johns Hopkins Medicine.

The researchers discovered that genes modified by methylation due to methyl donor exposure were likely responsible for this increased risk.
Measuring exhaled nitric oxide (NO) has no clinically significant impact on asthma control when used in conjunction with conventional treatment. Patients in the NO monitoring group received higher doses of inhaled corticosteroids, but this did not lead to better symptom control.
A large prospective study found that rhinitis is a powerful predictor of adult-onset asthma, with non-allergic and allergic rhinitis groups showing significant increased risks. The study suggests that treating allergic rhinitis may reduce the incidence of asthma, but more research is needed to confirm this.

Further studies are needed to determine if other genes outside the region occupy by ORMDL3 contribute to asthma susceptibility.
A Kaiser Permanente study found that obese adults with asthma are nearly five times more likely to be hospitalized for their condition. The study controlled for various risk factors and found that obese people with asthma have significantly worse asthma control and lower quality of life.
A recent New Zealand study investigated the relationship between obesity and asthma, ruling out systemic inflammation as a common factor. Despite not finding evidence of its involvement, researchers suggest that other possibilities, such as changes in innate immunity or dynamic lung function, may be worth exploring.
A recent study found that children who experienced physical or sexual abuse were more than twice as likely to have asthma. The researchers also discovered an association between stress, violence, and decreased glucocorticoid response, leading to airway inflammatory responses.
Researchers at Texas Instruments have developed a low-cost, portable spirometer using microelectromechanical system (MEMS) technology. The device can measure airflow and volume in a patient's lungs and is ideal for remote monitoring by healthcare workers.
Girls are more likely to experience persistent asthma, whereas boys tend to outgrow the condition. After nine years of monitoring, researchers found that girls' airway reactivity did not change significantly over time, while boys became increasingly tolerant to larger doses of methacholine.
Athletes with asthma face increased risk of symptoms due to high minute ventilation and poor air quality during exercise. Individualized management plans are crucial to comply with anti-doping regulations.
Research led by the University of New South Wales found that individuals with atopic diseases such as asthma and hay fever are up to 40% less likely to develop NHL if they have multiple conditions. Chronic atopy is associated with a reduced risk, particularly in B-cell NHL cases.

This study suggests chronic micro-aspiration of gastric fluid may be a key factor in linking GERD and asthma, offering new directions for treatment options.
Researchers found no therapeutic benefit in low-sodium diets for adults with asthma, contrary to past studies. The study suggests that further dietary research should focus on factors other than sodium.
A new study led by NYU Langone Medical Center researchers found that children who carry Helicobacter pylori are nearly 59% less likely to have asthma. The bacteria, which has co-existed with humans for at least 50,000 years, may strengthen the immune system and reduce the risk of allergic reactions.

A study by Johns Hopkins Children's Center found that 40% of pediatricians wouldn't reduce medication doses even if a child is well-controlled. The researchers suggest that pediatricians might benefit from a step-by-step tool to apply treatment guidelines and use different disease dimensions in their practice.
A new study suggests that more aggressive treatment of childhood eczema could help reduce the incidence of asthma in later life. The study, conducted by the University of Melbourne and others, found a strong association between childhood eczema and asthma into middle age.
A federally funded consortium of researchers led by Baylor College of Medicine found that children treated for HIV are at higher risk of developing asthma. CD4 cells increase in these children, leading to inflammation in lung tissue and worsening asthma symptoms.
