New paradigms in acute viral bronchiolitis: Is it time to change our approach?

Viral bronchiolitis is the most common pediatric acute respiratory infection leading to hospitalization, and it causes a significant healthcare burden worldwide. Current guidelines recommend supportive management after many clinical trials on specific therapies failed to demonstrate benefits. However, several studies in the past decade have revealed that bronchiolitis may not be a homogeneous disease, but instead may constitute an umbrella comprised of different "endotypes" and "phenotypes" based on patient characteristics, etiology, pathophysiological mechanisms, and clinical presentation.

Downstream Effects of Market Changes on Inhalers: Impacts on Individuals With Chronic Lung Disease.

COPD and asthma are two of the most common chronic lung diseases, affecting over 545 million people globally and 34 million in the United States. Annual health care costs related to chronic lung disease are estimated at €380 billion in the European Union, and $24-$50 billion in the United States averaging to $4,000 in out-of-pocket costs per person in the U.S.

Medical and social factors associated with prolonged length of stay for chronically ventilated children.

Objectives: This study seeks to determine the overall and post-intensive care unit (ICU) length of stay (LOS) for children with tracheostomies and chronic mechanical ventilation. We hypothesized that medical and social factors would be associated with prolonged LOS.

Study Design: This single-center retrospective review included children who were discharged after initiation of chronic ventilation via tracheostomy over an 8-year period (2015-2022).

Applying the dissemination and implementation sciences to allergy and immunology: A Work Group Report from the AAAAI Quality, Adherence, and Outcomes Committee.

Translating evidence-based practice (EBP) into real-world clinical settings often takes a considerable amount of time and resources. In allergy and immunology, the dissemination and implementation (D&I) sciences facilitate the study of how variations in knowledge, resources, patient populations, and staffing models lead to differences in the clinical care of asthma, allergic disease, and primary immunodeficiency. Despite the need for validated approaches to study how to best apply EBP in the real world, the D&I sciences are underutilized.

Reducing asthma attacks in disadvantaged school children with asthma: study protocol for a type 2 hybrid implementation-effectiveness trial (Better Asthma Control for Kids, BACK).

Background: Asthma is a leading cause of children's hospitalizations, emergency department visits, and missed school days. Our school-based asthma intervention has reduced asthma exacerbations for children experiencing health disparities in the Denver Metropolitan Area, due partly to addressing care coordination for asthma and social determinants of health (SDOH), such as access to healthcare and medications. Limited dissemination of school-based asthma programs has occurred in other metropolitan and rural areas of Colorado.

Type 2 Inflammation and Asthma in Children: A Narrative Review.

Increased understanding of the underlying pathophysiology has highlighted the heterogeneity of asthma and identified that most children with asthma have type 2 inflammation with elevated biomarkers, such as blood eosinophils and/or fractional exhaled nitric oxide. Although in the past most of these children may have been categorized as having allergic asthma, identifying the type 2 inflammatory phenotype provides a mechanism to explain both allergic and non-allergic triggers in pediatric patients with asthma. Most children achieve control with low to medium doses of inhaled corticosteroids.

Developing a Social Determinants of Health Needs Assessment for Colorado Kids (SNACK) Tool for a School-Based Asthma Program: Findings from a Pilot Study.

Background: School-based asthma programs effectively address poorly controlled asthma and asthma disparities, especially when coupled with screening for and addressing social determinants of health (SDOH) needs. Existing screening tools are tailored to clinical settings; therefore, we sought to develop a community-based SDOH screening tool.

Design/methods: We used a four-phase iterative design process to develop and pilot a community-based screening tool.

Notes From the Field: Diverse Partner Perspectives Improve the Usability and Equity Focus of Implementation Guides.

Context: School-based asthma programs (SBAPs) have improved health and educational disparities among youth with asthma.

Design: To support scaling out effective SBAPs, our school partners identified a need for online implementation guides that are "always available," to meet the needs of school nurses' demanding schedules. School nurses play a key role in the adoption and implementation of SBAPs, so it is important to ensure the implementation guide would be highly usable and acceptable to them.

Understanding Core Community Needs for School-Based Asthma Programming: A Qualitative Assessment in Colorado Communities.

Objectives: Asthma is one of the most prevalent chronic conditions affecting approximately 8.5% of children in Colorado. Our school-based asthma program (SBAP) has effectively improved asthma control and reduced asthma disparities among children but has been largely limited to the Denver area.

Computed tomographic findings in TBX4 mutation: a common cause of severe pulmonary artery hypertension in children.

Background: Mutations in the T-Box 4 (TBX4) gene are a lesser-known cause of heritable pulmonary arterial hypertension (PAH). Patients with heritable PAH typically have worse outcomes when compared with patients with idiopathic PAH, yet little is known about the phenotypical presentation of this mutation.

Objective: This article reviews the pattern of chest CT findings in pediatric patients with PAH and TBX4 mutations and compares their radiographic presentation with those of age-matched patients with PAH but without TBX4 mutations.

Is the assessment of asthma treatment efficacy sufficiently comprehensive?

The goal of asthma guideline therapy is to achieve disease control, by minimizing impairment and decreasing the risk of exacerbations and adverse effects of the disease and its treatment. The primary objective of most clinical trials of biologics for severe asthma is a reduction in exacerbation rate. Recently, studies with patients at the lower guideline steps have also selected exacerbation reduction as a primary objective.

Assessing the contributions of phylogenetic and environmental determinants of allergic cosensitization to fungi in humans.

Background: Understanding how allergies to 1 environmental fungus can lead to cosensitization to related fungi is important for the clinical management of allergies. Cosensitization can be caused by monosensitization combined with antibody cross-reactivity, or by coexposures driving independent sensitizations. A pioneering study showed that patterns of IgE cosensitization among 17 fungal species mirror fungal phylogeny.

Fifty Years of Unraveling the Clinical Pharmacology of Corticosteroids.

This review will highlight portions of Dr. William Jusko's and colleagues' work that affected the clinical use and study of corticosteroids in acute and chronic disease management. Selected publications related to corticosteroid pharmacokinetics and pharmacodynamics from the 1970s through today were included in this review, with a focus on the foundational human-based studies conducted in the 1970s-1990s.

Fungal allergen sensitization: Prevalence, risk factors, and geographic variation in the United States.

Background: Many fungal species are associated with the pathogenesis of allergic disease, yet most epidemiologic studies on IgE-mediated fungal sensitization have only included a few species.

Objective: We investigated fungal allergen sensitization prevalence, risk factors, and geographic variation in the United States.

Methods: From 2014 to 2019, a total of 7,912,504 serum-specific IgE (sIgE) test results for 17 fungal species were measured in 1,651,203 patients aged 0-85 years by a US-wide clinical laboratory.

Infection, Allergy, and Inflammation: The Role of in Cystic Fibrosis.

(Af) is a mold frequently detected in airway samples from people with cystic fibrosis (pwCF). Abnormal airway mucus may allow Af to germinate, resulting in airway infection or an allergic response. While Af is known to increase morbidity in pwCF, individual responses and the degree of impact on lung disease vary.

Encouraging adherence in adolescents with asthma using financial incentives: An RCT.

Background: Medication adherence in adolescents remains a significant management challenge and innovative strategies are needed to improve medication adherence. Financial incentives have been used to improve outcomes for health behaviors among adults, but have not been well-studied among adolescents. The objective of this study was to test if a modest financial incentive improved medication adherence in adolescents with asthma compared with a control group.
