By targeting treatment at the carotid bodies, they found that blocking receptors during an asthma attack can eliminate symptoms.
Researchers analyzed children's asthma management and found that environmental exposures like secondhand smoke and pet ownership were not significant factors in improving asthma control. Once asthma guidelines are followed, these exposures do not impact overall asthma improvement.
A University of Utah engineering study shows that smart controllers for home heating and cooling systems can clean pollution with minimal additional energy costs. The 'SmartAir' setting, which turns on the HVAC fan based on both temperature and air quality, cleaned the air almost as well as continuous operation but used 58% less energy.

A new study has found that people with asthma are more likely to become obese, especially if their asthma begins in adulthood or if they have non-allergic asthma. The research, which followed over 8,600 participants for two decades, suggests the relationship between asthma and obesity is more complex than previously thought.
Researchers have discovered a marker that can help identify patients with severe asthma who are likely to respond well to new treatments. The marker targets inflammatory cells called eosinophils, which play a key role in the condition.

A new diagnostic test that uses a simple nasal brush to identify mild to moderate asthma has been developed by Mount Sinai researchers. The test, which uses machine learning algorithms and RNA sequencing, can differentiate asthma from other respiratory conditions and is less expensive than traditional pulmonary function testing.
A new study suggests that vaccinating asthmatic children against the flu could significantly reduce their risk of needing hospitalization for an asthma attack. The study found that kids with influenza or parainfluenza had a 37-per-cent or more chance of not responding to treatment, compared to 13 per cent for children without a virus.
Asthma management is complicated by heterogeneity and variability, making it difficult to implement optimal strategies. The role of physicians in managing asthma complexity is particularly challenging, requiring knowledge, dedication, and experience.
Researchers from the University of Pennsylvania School of Medicine have identified the source of IL-25, an inflammatory cytokine linked to chronic rhinosinusitis and asthma. The study found that solitary chemosensory cells in the sinuses produce IL-25, which can recruit immune cells and lead to inflammation.
A study found that patients hospitalized for asthma who received antibiotics had longer hospital stays and higher costs, but no reduced risk of treatment failure. Antibiotic-related diarrhea was also more common in treated patients.
Researchers found a new treatment, dupilumab, effective in treating severe asthma by blocking key drivers of inflammation. The study showed improved asthma symptoms, lung function, and reduced need for corticosteroids.
Dupilumab alleviates asthma symptoms and improves lung function in moderate to severe asthma patients. The drug significantly reduced asthma exacerbations by half in some patients, with improved rates of emergency room visits and hospitalizations.
A long-term study has found that exposure to ozone at birth is associated with an increased risk of developing asthma, allergic rhinitis, and eczema in childhood. The study, which followed 1,881 children from birth to age 17, found that even small increases in ozone exposure were linked to a higher risk of developing these conditions.
Researchers have found a patient-centric treatment that works for people with mild asthma, using an as-needed combined-drug inhaler. The study, led by Paul O'Byrne, showed the inhaler was superior to conventional treatment strategies in reducing asthma attacks and improving symptom control.
A recent study published in Pediatrics found that no single category of intervention was effective in reducing hospital readmission for children with asthma. However, multimodal interventions that combined multiple categories showed promise in reducing the risk of readmission between 30 days and one year after initial discharge.
A high-fiber diet increases survival in influenza-infected mice by setting the immune system at a healthy level of responsiveness. It also boosts antiviral immunity by activating T cells, mediated by changes in gut bacteria composition.
A study found that asthma mortality rates are falling among younger people in the poorest areas compared to the wealthiest, but remain higher in older adults. Regional variations persist, with significant differences in outcomes across England.
A recent study published in the Journal of Allergy and Clinical Immunology found that children living close to major roadways had nearly three times the odds of pediatric asthma compared to those who lived farther away. The researchers also discovered a stronger link between lifetime pollution and asthma among school-age girls.
Researchers found variations in immune cells in children from higher vs lower socioeconomic status families. This disparity affects asthma control and suggests a link between socioeconomic factors and immune system dysfunction.
A new study published in Frontiers in Psychiatry found a significant link between common allergic diseases and a broad spectrum of psychiatric disorders. Patients with asthma and hay fever were found to have a 1.66-fold increased risk of developing a psychiatric disorder within a 15-year period.
Researchers found that children with asthma often miss their daily medication due to barriers such as forgetfulness and running out of medication. The study suggests that improving communication among patients, families, and pediatric clinicians is crucial to ensure consistent use of daily anti-inflammatory medication.
A new study published in the European Respiratory Journal found that long-term exposure to high levels of road traffic and ozone significantly increases the risk of asthma symptoms and medication use. The study also identified a biological marker, 8-isoprostane, which is exhaled in the breath and linked to tissue damage in the lungs.

A new study suggests that air pollution from traffic-related emissions is a significant contributor to childhood asthma cases in Bradford, with up to 24% of annual cases potentially attributed to this factor. The research highlights the need for policies aimed at reducing traffic-related air pollution to mitigate its effects on childre...
Having measles in early childhood may predispose individuals to asthma-like symptoms and airway obstruction if they also smoked. Adults with a significant history of asthma and smoking are at a higher risk of developing chronic obstructive pulmonary disease.
A team of scientists has identified a human protein called interleukin-33 (IL-33) that reacts to various environmental allergens, including mold, pollen, and cockroaches. This discovery establishes a direct link between genetics and the environment, and offers new potential targets for treatment of allergic diseases.
A clinical trial found that increasing inhaled steroids at the first signs of an asthma attack does not prevent attacks in children with mild to moderate asthma. Children in the high-dose group experienced slower growth rates compared to those on low-dose medication.
Researchers found that using a single corticosteroid and long-acting bronchodilator treatment for both daily asthma control and rescue relief is more effective than separate medications. This approach significantly reduces asthma attacks, hospitalizations, and emergency room visits.
