Elevated triglyceride-glucose index is independently associated with a 6% higher risk of severe asthma exacerbation. Routine bronchoscopy before biologic therapy for severe uncontrolled asthma can help identify specific asthma phenotypes. Infant food allergies were associated with reduced lung function and an increased risk of asthma in childhood. Household poverty is an outcome of asthma care utilization according to a study assessing the impact of poverty on asthma. Extreme temperature exposure during pregnancy and early infancy can harm lung function in female newborns. Exposure to agricultural burning is associated with an increased prevalence of respiratory symptoms in children. Living near fast food restaurants is linked to reduced lung function changes in children with asthma. Family smoking exposure is associated with IgE production, potentially increasing the risk of airway allergies. Many African Americans with COPD re not accurately diagnosed using the current fixed-ratio spirometry criteria. Introducing biologic therapies for severe asthma led to significant reductions in asthma-related hospital admissions. Uncontrolled severe asthma causes more health impairment and lower productivity compared to controlled severe asthma. High levels of asthma was observed in pediatric patients who experienced asthma exacerbations after spikes in air pollution. Empowered asthma patients adhere better with tailored education and improved communication.
Comorbidities significantly influence asthma control in older adults. Babies born preterm have a higher risk of developing asthma and COPD in adulthood. Asthma accelerates white and gray matter microstructural changes associated with aging and neurodegeneration. A recent study among US adults found a significant correlation between food insecurity and asthma. Interaction between histamine-releasing factor and immunoglobulin may promote inflammation in patients with severe asthma. Higher GERD severity is associated with reduced lung function in patients with asthma. Children and adolescents with status asthmaticus who are obese have a higher likelihood of requiring mechanical ventilation.
