OBJECTIVES To establish longitudinal validation of a new tool, the Asthma Symptom Tracker (AST). AST combines weekly use of the Asthma Control Test with a color-coded graph for visual trending. METHODS Prospective cohort study of children age 2 to 18 years admitted for asthma. Parents or children (n = 210) completed baseline AST assessments during(More)
Inhaled irritants activate transient receptor potential ankyrin-1 (TRPA1), resulting in cough, bronchoconstriction, and inflammation/edema. TRPA1 is also implicated in the pathogenesis of asthma. Our hypothesis was that particulate materials activate TRPA1 via a mechanism distinct from chemical agonists and that, in a cohort of children with asthma living(More)
BACKGROUND AND OBJECTIVES The Joint Commission introduced 3 Children's Asthma Care (CAC 1-3) measures to improve the quality of pediatric inpatient asthma care. Validity of the commission's measures has not yet been demonstrated. The objectives of this quality improvement study were to examine changes in provider compliance with CAC 1-3 and associated(More)
OBJECTIVES The goals were (1) to identify evidence-based clinical process measures that are appropriate, feasible, and reliable for assessing the quality of inpatient asthma care for children and (2) to evaluate provider compliance with these measures. METHODS Key asthma quality measures were identified by using a modified Rand appropriateness method,(More)
OBJECTIVE To determine the relationship between allelic variations in genes involved in fluticasone propionate (FP) metabolism and asthma control among children with asthma managed with inhaled FP. STUDY DESIGN The relationship between variability in asthma control scores and genetic variation in drug metabolism was assessed by genotyping 9 single(More)
This paper describes the development and evaluation of an innovative application designed to engage children and their parents in weekly asthma self-monitoring and self-management to prompt an early response to deteriorations in chronic asthma control, and to provide their physicians with longitudinal data to assess the effectiveness of asthma therapy and(More)
BACKGROUND Pediatric asthma affects 7.1 million American children incurring an annual total direct healthcare cost around 9.3 billion dollars. Asthma control in children is suboptimal, leading to frequent asthma exacerbations, excess costs, and decreased quality of life. Successful prediction of risk for asthma control deterioration at the individual(More)
Transient receptor potential (TRP) channels are activated by environmental particulate materials. We hypothesized that polymorphic variants of transient receptor potential vanilloid-1 (TRPV1) would be uniquely responsive to insoluble coal fly ash compared with the prototypical soluble agonist capsaicin. Furthermore, these changes would manifest as(More)
