AbstractBackgroundMethodsResultConclusionsPrevious studies have suggested a potential link between pediatric asthma and psychiatric disorders. However, the causal relationship between pediatric asthma and psychiatric disorders is unclear. Therefore, we used Mendelian randomization to explore causal relationships between pediatric asthma and depression, anxiety disorders, and attention deficit and hyperactivity disorder (ADHD).Genome-wide association studies (GWAS) meta-analyses with the largest possible sample size and independent individuals from European ancestry were selected. The genetic data for depression and anxiety are from FinnGen consortium, while the genetic data for ADHD is from the Psychiatric Genomics Consortium. Inverse variance weighted (IVW) was the main analysis method. The heterogeneity of the instrumental variables (IVs) was assessed using IVW, and the horizontal pleiotropy of the IVs was assessed using MR-Egger.The IVW results showed a significant causal relationship between pediatric asthma and depression (OR = 1.08, 95% CI = 1.02–1.15;
p = 0.013). However, there is no evidence to suggest a causal relationship between pediatric asthma, anxiety, and ADHD. Reverse MR suggests a significant causal relationship (OR = 1.27, 95% CI [1.14–1.41],p = 9.64E − 06) between ADHD and pediatric asthma using the IVW method.Our findings suggest a causal relationship between pediatric asthma and an increased risk of depression. Additionally, we found that ADHD is significantly associated with a higher risk of pediatric asthma. [ABSTRACT FROM AUTHOR]- Published

AbstractObjectiveMethodsResultsConclusionsPediatric asthma management faces challenges in medication delivery through oral inhalation devices. While dry powder inhalers (DPIs) are increasingly prescribed to children, many do not receive their prescribed dosage due to insufficient inspiratory flow. This study investigates the utilization of metered-dose inhalers (MDIs) and DPIs among pediatric patients with asthma, focusing on medication delivery challenges.Two survey cohorts comprising a total of 42 caregivers of patients with asthma were conducted. Modifications in the second cohort addressed neutral Likert scale responses to obtain more nuanced feedback.Caregivers expressed concerns about uncertainties in their child’s ability to use both MDIs and DPIs and challenges in ensuring proper dosage. Notably, 42% of caregivers in the second cohort rated their child’s inhaler usage as unable, indicating a significant worry about the efficacy of current delivery methods. Additionally, 50% of caregivers across both cohorts expressed uncertainties about their child receiving the full medication dosage. In response to identified challenges with DPIs, an adaptor device emerged as a potential solution, with caregivers exhibiting positive perceptions post-exposure. Features prioritized for the device include ease of use and assurance of dose delivery.The study highlights caregiver preferences and the need for innovations to ensure effective medication delivery for pediatric asthma patients. A DPI adaptor device shows promise in addressing technical issues and alleviating caregiver concerns, ultimately contributing to more effective asthma management. Future research should refine these devices based on caregiver feedback to meet the evolving needs of the pediatric asthma population. [ABSTRACT FROM AUTHOR]

AbstractObjectiveMethodsResultsConclusionsThis study aimed to evaluate the effect of mothers’ knowledge about asthma management on quality of life and asthma control among children with asthma in Palestine.This cross-sectional study was carried out by mothers of children with asthma in Palestine in four major public hospitals. Mothers of a total of 220 were selected randomly
via a computerized system. Data were collected using Pediatric Asthma Quality of Life (PAQLQ), an Asthma Control Test (ACT), and the mothers’ Self-Practices and Knowledge (SPK) of asthma management questionnaire. Statistical analysis was performed using SPSS (V25).A total of 220 mothers of children with asthma were randomly selected and invited to participate but 182 agreed to participate, with a response rate of 83%. The mean age of participant children was 9.7 ± 2.72 years, and the mean age of mothers was 34.5 ± 9.6 years. The mean score of the QoL was 3.91(SD ± 1.61) out of 7. Most participant children had uncontrolled asthma with a total mean score of 14.13(SD ± 5.23) on the ACT. The mean score of mothers’ SPK level was 2.12(SD ± 0.83) with a total mean score of 42.13 ± 3.68 out of 68, which indicated a moderate level of knowledge and there was a strong correlation between mothers’ SPK and children’s QoL.The investigation showed that mothers of children with asthma had moderate SPK, and the children had uncontrolled asthma with poor QoL. These findings suggest developing educational initiatives to enhance parents’ asthma-related knowledge and skills to improve their children’s asthma-related quality of life and asthma control.

PSYCHOLOGICAL well-being , *ASTHMA in children , *PSYCHOLOGICAL adaptation , *PARENTAL influences , *MOTHERS , *SEPARATION anxiety - Abstract
Background/Objectives: The literature reports that emotional disorders in asthmatic children and their parents may affect asthma control. This research explores the baseline psychological well-being of asthmatic children and their mothers' and fathers' psychological functioning, focusing on the influence of the parents' anxiety and separation anxiety on children's asthma. Methods: In this cross-sectional study, we enrolled children with non-severe asthma and their parents, and a group of healthy children and their parents. The asthmatic children underwent anamnestic investigation, including asthma control and spirometry. Then, both the asthmatic and control triads filled a survey assessing their psychological functioning. Results: Among the 40 asthmatic children enrolled (8–18 years old), most had good clinical control maintained with GINA (Global Initiative for Asthma) therapy step 1–2 (14 patients, 35%) or step 3–4 (26 patients, 65%); 12 patients (30%) had at least one steroid course in the year before enrollment. They exhibited normal psychological adjustment but elevated levels of general (U = 179,500; p < 0.001) and state anxiety (U = 170,000; p < 0.001) compared to healthy peers. Additionally, the asthmatic children's mothers displayed higher levels of separation anxiety compared to the fathers (t = −2.865, p = 0.006). Increased separation anxiety in the mothers corresponded to a history of at least one exacerbation in the previous year. Conclusions: The asthmatic children exhibited normal psychological adjustment with higher general and state anxiety. Also, their mothers showed greater levels of separation anxiety compared to their fathers. Lastly, higher mothers' separation anxiety corresponded to a history of at least one exacerbation in the previous year. The influence of the parents' psychological well-being on the children's asthma control was previously unexplored. [ABSTRACT FROM AUTHOR]

To address pediatric asthma disparities on the South Side of Chicago, a community health worker (CHW) home visiting intervention was implemented collaboratively by academic institutions and community based health centers. This evaluation assessed the effectiveness of this longitudinal quality improvement CHW intervention in reducing asthma morbidity and healthcare utilization. All patients aged 2–18 who met the high-risk clinical criteria in outpatient settings or those who visited the ED due to asthma were offered the program. A within-subject study design analyzed asthma morbidity and healthcare utilization at baseline and follow-up. Multivariable mixed-effects regression models, adjusted for baseline demographic and asthma characteristics, were used to assess changes over time. Among 123 patients, the average age was 8.8 (4.4) years, and 89.3% were non-Hispanic black. Significant reductions were observed in the average daytime symptoms days (baseline 4.1 days and follow-up 1.6 days), night-time symptoms days (3.0 days and 1.2 days), and days requiring rescue medication (4.1 days and 1.6 days) in the past two weeks (all p < 0.001). The average number of emergency department visits decreased from 0.92 one year before to 0.44 one year after program participation, a 52% reduction (p < 0.001). No significant difference was found in hospital admissions. These results support the use of a collaborative approach to implement the CHW home visiting program as part of standard care for pediatric asthma patients in urban settings. This approach has the potential to reduce asthma disparities and underscores the valuable role of CHWs within the clinical care team. [ABSTRACT FROM AUTHOR]

AbstractObjectiveMethodsResultsConclusionAsthma is a common chronic respiratory disease in children. Understanding incidence and mortality trends is crucial for prevention and intervention strategies.Data from the Global Burden of Disease (GBD) study were used to analyze asthma incidence and mortality trends among children aged 0–14 in 204 countries from 1990 to 2019. The 30-year trends were calculated using the Estimated Annual Percentage Change (EAPC).Globally, pediatric asthma cases increased from 18,857,697 in 1990 to 20,191,786 in 2019. Incidence rates for children <5, 5–9, and 10–14 years are 1509.36, 980.25, and 586.95 per 100,000, respectively. Over 30 years, pediatric asthma mortality rates significantly decreased from 1.59 to 0.51 per 100,000, with minimal gender differences. High-income North America, Tropical Latin America, and the Caribbean show the highest incidence rates at 3203.2, 2493.83, and 2314.8 per 100,000. The USA, Puerto Rico, and Haiti have the highest national rates at 3357.17, 2695.30, and 2605.38 per 100,000. Regions with higher Sociodemographic Index levels tend to have higher incidence rates. Pediatric asthma prevalence varies by region and age group.Our study of asthma incidence and mortality rates among children aged 0–14 across 204 countries from 1990 to 2019 reveals significant global disparities. These findings underscore the influence of socioeconomic and environmental factors on asthma prevalence and outcomes. [ABSTRACT FROM AUTHOR]

Background: The immunological mechanisms behind the clinical association between asthma and obesity in adolescence are not fully understood. This study aimed to find new plasma protein biomarkers associated specifically with coincident asthma and obesity in adolescents. Methods: This was a cross‐sectional study in children and adolescents 10–19 years old (N = 390). Relative plasma concentrations of 113 protein biomarkers related to inflammation and immune response were determined by proximity extension assay (Target 96; Olink, Uppsala, Sweden). Differences in protein concentrations between healthy controls (n = 84), subjects with asthma (n = 138), subjects with obesity (n = 107), and subjects with both asthma and obesity (AO; n = 58) were analyzed by ANCOVA, adjusting for age and sex, and in a separate model adjusting also for the sum of specific IgE antibody concentrations to a mix of food allergens (fx5) and aeroallergens (Phadiatop). Proteins elevated in the AO group but not in the obesity or asthma groups were considered specifically elevated in asthma and obesity. Results: Five proteins were elevated specifically in the AO group compared to controls (here sorted from largest to smallest effect of asthma and obesity combined): CCL8, IL‐33, IL‐17C, FGF‐23, and CLEC7A. The effects of adjusting also for specific IgE were small but IL‐33, IL‐17C, and FGF‐23 were no longer statistically significant. Conclusion: We identified several new potential plasma biomarkers specifically elevated in coincident asthma and obesity in adolescents. Four of the proteins, CCL8, IL‐33, IL‐17C, and CLEC7A, have previously been associated with viral mucosal host defense and Th17 cell differentiation. [ABSTRACT FROM AUTHOR]

Kjellberg, Sanna, Olin, Anna-Carin, Schiöler, Linus, and Robinson, Paul D.
- Abstract
AbstractBackgroundMethodsResultsConclusionsSmall airway dysfunction (SAD) is increasingly recognized as an important feature of pediatric asthma yet typically relies on spirometry-derived FEF25–75 to detect its presence. Multiple breath washout (MBW) and oscillometry potentially offer improved sensitivity for SAD detection, but their utility in comparison to FEF25–75, and correlations with clinical outcomes remains unclear for school-age asthma. We investigated SAD occurrence using these techniques, between-test correlation and links to clinical outcomes in 57 asthmatic children aged 8–18 years.MBW and spirometry abnormality were defined as
z -scores above/below ± 1.96, generating MBW reference equations from contemporaneous controls (n = 69). Abnormal oscillometry was defined as > 97.5th percentile, also from contemporaneous controls (n = 146). Individuals with abnormal FEF25–75, MBW, or oscillometry were considered to have SAD.Using these limits of normal, SAD was present on oscillometry in 63% (resistance at 5–20 Hz; R5-R20; >97.5th percentile), on MBW in 54% (Scond;z -scores> +1.96) and in spirometry FEF25–75 in 44% of participants (z -scores< −1.96). SAD, defined by oscillometry and/or MBW abnormality, occurred in 77%. Among those with abnormal R5-R20, Scond was abnormal in 71%. Correlations indicated both R5-R20 and Scond were linked to asthma medication burden, baseline FEV1 and reversibility. Additionally, Scond correlated with FENO and magnitude of bronchial hyper-responsiveness. SAD, detected by oscillometry and/or MBW, occurred in almost 80% of school-aged asthmatic children, surpassing FEF25–75 detection rates.Discordant oscillometry and MBW abnormality suggests they reflect different aspects of SAD, serving as complementary tools. Key asthma clinical features, like reversibility, had stronger correlation with MBW-derived Scond than oscillometry-derived R5-R20. [ABSTRACT FROM AUTHOR]- Published

Asthma exacerbations are a frequent reason for pediatric emergency medical services (EMS) encounters. The objective of this study was to examine the implementation of evidence-based treatments for pediatric asthma in a regional consortium of EMS agencies. This retrospective study applied the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) implementation framework to data from an EMS agency consortium in the Cincinnati, Ohio region. The study analyzed one year before an oral systemic corticosteroid (OCS) option was added to the agencies' protocol, and five years after the protocol change. We constructed logistic regression models for the primary outcome of Reach, defined as the proportion of pediatric asthma patients who received a systemic corticosteroid. We modeled Maintenance (Reach measured monthly over time) using time series models. A total of 713 patients were included, 133 pre- and 580 post-protocol change. In terms of Reach, 3% (n = 4) of eligible patients received a systemic corticosteroid pre-OCS versus 20% (n = 116) post-OCS. Multivariable modeling of Reach revealed the study period, EMS transport time, months since implementation of OCS, and number of bronchodilators administered by EMS as significant covariates for the administration of a systemic corticosteroid. For Maintenance, it took approximately two years to reach maximal administration of systemic corticosteroids. Indicators of asthma severity and time since the protocol change were significantly associated with EMS administration of systemic corticosteroids to pediatric asthma patients. The two-year time for maximal Reach suggests further work is required to understand how to best implement evidence-based pediatric asthma treatments in EMS. [ABSTRACT FROM AUTHOR]

Despite the growing concern over the impact of ambient fine particulate matter (PM2.5) on respiratory health, studies on the association between PM2.5 and childhood asthma in Vietnam have remained relatively sparse.The study aimed to evaluate the short-term effects of PM2.5 on asthma hospital admissions in Ho Chi Minh City (HCMC), the most populous city in Vietnam. The PM2.5 database from 2016 to 2019 was collected at two fixed monitoring stations. The health database was collected from all three children's hospitals. A time-series regression analysis was conducted to examine the associations between the daily PM2.5 concentration and hospitalizations for asthma.A total of 11,223 records of children under five years old hospitalized for asthma were collected, of which 64 % were male and 70 % were aged 2 to under five years old. The daily mean PM2.5 concentration over the study period was 28.2 μg/m3. Each 10 μg/m3 increase in PM2.5 at lag2, lag3, and lag04, we found that the excess risk of total asthma hospital admission was 2.71 %, 2.63 %, and 3.9 %, respectively. According to the subgroup analysis, female gender and children aged from two to under five years had more significant effects.PM2.5 poses a risk to children's health; therefore, the local authority should prioritize improving the air quality.

Background: Outdoor aeroallergens, such as pollens and molds, are known triggers of asthma exacerbation; however, few studies have examined children’s aeroallergen response based on sensitization. Objective: Our aim was to compare the relative impact of aeroallergen levels on asthma exacerbation between pediatric patients with asthma who tested positive or negative for sensitization to particular allergens. Methods: A case-crossover design study was conducted to examine associations between outdoor aeroallergen levels and asthma exacerbation events among children living in Philadelphia, Pennsylvania, who were treated within a large pediatric care network. Sensitization to common allergens was characterized in a subset of patients with asthma exacerbation who had undergone skin prick testing (5.5%). Odds ratios (ORs) and 95% CIs were estimated in all patients with asthma exacerbation and in those sensitized or not sensitized to aeroallergens. Results: Children who were sensitized to a particular allergen had higher odds of asthma exacerbation with exposure to the allergen (ie, early-season tree pollen, oak tree pollen, early-season weed pollen, and late-season molds) than did all patients with asthma or nonsensitized patients. For example, the association between early-season tree pollen and asthma exacerbation among sensitized children (>90th percentile vs ≤25th, OR = 2.28 [95% CI = 1.23-4.22]) was considerably stronger than that estimated among all patients (OR = 1.34 [95% CI = 1.19-1.50]), and it was also substantially different from the lack of association seen among nonsensitized children (OR = 0.89 [95% CI = 0.51-1.55] [P value for heterogeneity = .03]). Conclusion: More prevalent allergy testing may be useful for prevention of asthma exacerbation by informing interventions targeted to sensitized children and tailored for particular aeroallergens.

This post hoc analysis of the Phase 3 LIBERTY ASTHMA VOYAGE study (NCT02948959) evaluated the efficacy of dupilumab in children aged 6 to 11 years with moderate-to-severe asthma with a type 2 inflammatory phenotype (blood eosinophil count ≥ 150 cells/μL or fractional exhaled nitric oxide [FeNO] ≥ 20 ppb) and a history of 1, 2, or ≥ 3 prior exacerbations. The impact of baseline type 2 biomarker levels on the efficacy of dupilumab in this population was also investigated.Patients and Methods: Patients were stratified by the number of exacerbations in the prior year (1, 2, or ≥ 3) and level of FeNO or blood eosinophil count at baseline. Endpoints included rate of severe exacerbations, percentage of non-exacerbators, and change from baseline in both lung function parameters (pre- and post-bronchodilator [BD] percent predicted forced expiratory volume in 1 s (ppFEV1) and ppFEV1/forced vital capacity [FVC] ratio) and Asthma Control Questionnaire 7 Interviewer-Administered (ACQ-7-IA) score.Results: A total of 350 patients were included in this analysis. Across patients with 1, 2, or ≥ 3 prior exacerbations and different levels of type 2 biomarkers, dupilumab reduced the risk of severe asthma exacerbations vs placebo by 53.0– 96.0% and improved both pre-BD ppFEV1 and pre-BD FEV1/FVC ratio at Week 52. Dupilumab led to significant reductions in ACQ-7-IA scores in all groups of patients by Week 52.Conclusion: In children with uncontrolled, moderate-to-severe asthma with a type 2 phenotype, dupilumab consistently reduced the risk of asthma exacerbations, improved lung function, and reduced ACQ-7-IA scores, regardless of exacerbation history.

BackgroundPrenatal exposure to polycyclic aromatic hydrocarbons (PAH) may increase risk of pediatric asthma, but existing human studies are limited.ObjectivesWe estimated associations between gestational PAHs and pediatric asthma in a diverse US sample and evaluated effect modification by child sex, maternal asthma, and prenatal vitamin D status.MethodsWe pooled two prospective pregnancy cohorts in the ECHO PATHWAYS Consortium, CANDLE and TIDES, for an analytic sample of N = 1296 mother-child dyads. Mono-hydroxylated PAH metabolites (OH-PAHs) were measured in mid-pregnancy urine. Mothers completed the International Study on Allergies and Asthma in Childhood survey at child age 4-6 years. Poisson regression with robust standard errors was used to estimate relative risk of current wheeze, current asthma, ever asthma, and strict asthma associated with each metabolite, adjusted for potential confounders. We used interaction models to assess effect modification. We explored associations between OH-PAH mixtures and outcomes using logistic weighted quantile sum regression augmented by a permutation test to control Type 1 errors.ResultsThe sociodemographically diverse sample spanned five cities. Mean (SD) child age at assessment was 4.4 (0.4) years. While there was little evidence that either individual OH-PAHs or mixtures were associated with outcomes, we observed effect modification by child sex for most pairs of OH-PAHs and outcomes, with adverse associations specific to females. For example, a 2-fold increase in 2-hydroxy-phenanthrene was associated with current asthma in females but not males (RRfemale = 1.29 [95 % CI: 1.09, 1.52], RRmale = 0.95 [95 % CI: 0.79, 1.13]; pinteraction = 0.004). There was no consistent evidence of modification by vitamin D status or maternal asthma.DiscussionThis analysis, the largest cohort study of gestational PAH exposure and childhood asthma to date, suggests adverse associations for females only. These preliminary findings are consistent with hypothesized endocrine disruption properties of PAHs, which may lead to sexually dimorphic effects.

Introduction: We aimed to evaluate the longitudinal relationships, both at between- and within-person levels, that adherence to inhaled corticosteroidbased maintenance treatment and inhalation technique present with symptom control, exacerbations, and health-related quality of life (HRQoL) in children and adolescents with asthma. Methods: Participants (6-14 years old) from the ARCA (Asthma Research in Children and Adolescents) cohort--a prospective, multicenter, observational study (NCT04480242)--were followed for a period from 6 months to 5 years via computer-assisted telephone interviews and a smartphone application. The Medication Intake Survey-Asthma (MIS-A) was administered to assess the implementation stage of adherence, and the Inhalation Technique Questionnaire (InTeQ) was used to assess the five key steps when using an inhaler. Symptom control was measured with the Asthma Control Questionnaire (ACQ), and HRQL was measured with the EQ-5D and the Patient-Reported Outcomes Measurement Information System-Pediatric Asthma Impact Scale (PROMIS-PAIS). Multilevel longitudinal mixed models were constructed separately with symptom control, exacerbation occurrence, EQ-5D, and PROMIS-PAIS as the dependent variables. Results: Of the 360 participants enrolled, 303 (1,203 interviews) were included in the symptom control and exacerbation analyses, 265 (732) in the EQ-5D, and 215 (617) in the PROMIS-PAIS. Around 60% of participants were male subjects, and most of them underwent maintenance treatment with inhaled corticosteroids plus longacting β-agonists in a fixed dose (73.3%). Within-person variability was 83.6% for asthma control, 98.6% for exacerbations, 36.4% for EQ-5D, and 49.1% for PROMISPAIS. At the within-person level, patients with higher adherence had better symptom control (p = 0.002) and HRQoL over time (p = 0.016). Patients with a better inhalation technique reported worse HRQoL simultaneously (p = 0.012), but they showed better HRQoL in future assessments (p = 0.012). The frequency of reliever use was associated with symptom control (p < 0.001), exacerbation occurrence (p < 0.001), and HRQoL (p = 0.042); and boys were more likely to present better symptom control and HRQoL than girls. Conclusion: Our results confirm longitudinal associations at the within-person level of the two indicators of quality use of inhalers: for adherence to maintenance treatment with symptom control and HRQoL, and for the inhalation technique with HRQoL. Although treatment adherence was shown to be excellent, a third of the participants reported a suboptimal inhalation technique, highlighting the need for actions for improving asthma management of the pediatric population.

Introduction:Asthma is one of the most chronic noncommunicable diseases of childhood, affecting 1 in 12 children in the United States. The use of telemedicine for the management of pediatric asthma has shown improved health outcomes; however, it is important to understand what can impact its acceptance. The purpose of this review was to identify the facilitators and barriers to pediatric asthma management, as viewed by stakeholders. Methods:An electronic literature search was performed using PubMed, Scopus, and Cumulative Index to Nursing and Allied Health Literature Complete. Articles included in the review contained perceptions of the use of telemedicine for the management of pediatric asthma, as viewed by stakeholders. The socioecological model was used as the theoretical framework to extract data based on its five levels. Results:After reviewing full texts of 143 articles, 118 were excluded, leaving 25 articles included in this review. A majority of included articles focused on mobile health (m-Health) studies for the management of pediatric asthma, with the remaining articles studying synchronous telemedicine or a combination of modalities. Common themes were identified; however, most were focused on the use of m-Health and few studies contained the viewpoints of the caregiver, children, or providers regarding synchronous telemedicine. Discussion:This integrative review identified a number of facilitators and barriers for the management of asthma using telemedicine. However, more qualitative studies are needed to evaluate the perceptions of caregivers, patients, and primary providers regarding synchronous telehealth. It was also recognized that telemedicine may increase instead of reduce health care disparities. [ABSTRACT FROM AUTHOR]

The purpose of this study is to evaluate online-merge-offline (OMO)-based music therapy (MT) as a complementary option for asthma management in pediatric patients. A total of 86 children diagnosed with mild asthma were enrolled and treated with the same drug therapy. They were assigned into three groups: Music I group (standard medical care plus a single individualized MT session along with singing training and breathing exercise), Music II group (similar as Music I as well as further wind instrument playing), and Control group (standard medical care). Primary endpoints included pulmonary function tests FEV1, FVC, FEV1/FVC, MMEF 75/25, and PEF, c-ACT, PAQLQ, and PACQLQ. After 6 months of continuous intervention of MT, significant differences in FEV1, FVC, MMEF75/25, PEF, c-ACT score, PAQLQ, PACQLQ (p < 0.001), and FEV1/FVC (p < 0.05) were observed among Music I, Music II, and Control groups. Besides, FEV1, FVC, FEV1/FVC, MMEF75/25, and PEF showed positive trends in Music I and Music II groups compared to those in Control group (p < 0.05). The c-ACT score of children was significantly increased in Music I (p < 0.001) and II (p < 0.001) groups in contrast with Control group. Children in Music I and II groups had better quality of life than those in Control group (PAQLQ, p < 0.001), and the parents in Music I and II groups also showed better quality of life than those in Control group (PACQLQ, p < 0.001). Conclusion: As a child-friendly, low-risk, and convenient intervention, the OMO-based MT has a positive impact on pediatric asthma management during the COVID-19 pandemic. What is Known: • A few findings proved the positive effect of MT on pediatric asthma. What is New: • Our study further proving the validation and effectiveness of MT with OMO-based model on pediatric asthma, wind instrument playing has a greater impact on pediatric asthma control via small airways and might be recommended to mix to singing and breathing to improve effectiveness of MT for asthmatic children.

Background: Poor adherence to inhaled corticosteroids (ICS) is a significant challenge in pediatric asthma, contributing to health inequities. Text-message reminders for ICS therapy are an evidence-based approach that improves pediatric asthma medication adherence, yet has not been widely adopted into practice, partly due to lack of (1) participant input on design and implementation and (2) use of sustainable community linkages. Remote Asthma Link™ (RAL) seeks to fill this gap as a school-linked text-message intervention wherein parents of children with poorly controlled asthma received daily, 2-way text-message reminders for preventive inhaler use. Responses were shared with school nurses who conducted remote check-ins with families. Enrolled children, largely from underserved backgrounds, experienced improvements in medication adherence and asthma health outcomes. While initial results were promising, we have yet to elicit participant input to refine the protocol for more widespread implementation. Objective: Examine participant perspectives on barriers and facilitators of RAL implementation. Methods: Semistructured interviews were conducted May–June 2022 with intervention participants: 10 parents, 7 school nurses, and 4 pediatric providers (n = 21) until thematic saturation was reached. Interview transcripts were coded using thematic analysis. Results: Several facilitators for RAL implementation were identified, including ease of use and accessibility, personal connection to the school nurse, and receipt of a visual notification for habit formation. Barriers included challenges with school nurses reaching parents, poor understanding of program expectations, and lack of reimbursement structure. Participant-proposed solutions to barriers included utilizing alternate communication methods (eg, social media), educational sessions, and meeting with payors to consider reimbursement models. Conclusion: RAL is a school-linked text-message intervention demonstrating promise in improving outcomes and equity in asthma care. Key implementation facilitators, barriers, and proposed solutions will inform protocol adaptations to promote successful implementation of this and other text-message interventions into clinical practice.

Background: Many children seen in the Emergency Department (ED) for asthma do not follow-up with their primary care provider. Text messaging via short message service (SMS) is a ubiquitous, but untested means of providing post-ED asthma follow-up care.Objective: To evaluate responses to an asthma assessment survey via SMS following an ED visit and estimate the likelihood of response by sociodemographic and clinical characteristics. Methods: We recruited 173 parents of children 2–17 years-old presenting for ED asthma care to receive a follow-up text (participation rate: 85%). One month later, parents received via SMS a 22-item survey that assessed asthma morbidity. We assessed response rates overall and by various sociodemographic and clinical characteristics, including age, parental education, and indicators of asthma severity.Results: Overall, 55% of parents (n = 95) responded to the SMS survey. In multivariable logistic regression (MLR), parents who graduated high school had a four-fold higher response rate compared to parents with less than a high school degree (OR: 4.05 (1.62, 10.13)). More parents of children with oral steroid use in the prior 12 months responded to survey items (OR: 2.53 (1.2, 5.31)). Reported asthma characteristics included: 48% uncontrolled, 22% unimproved/worse, 21% with sleep disruption, and 10% who were hospitalized for asthma.Conclusions: Text messaging may be a viable strategy to improve post-ED asthma assessment and to identify children with persistent symptoms in need of enhanced care or modification of care plans.

Background. Asthma is a chronic illness that causes recurrent inflammation and airway constriction. The primary risk factors for asthma development are exposure to environmental allergens and house dust mites, which can trigger deoxyribonucleic acid (DNA) damage. Oxidative stress can also cause DNA impairments and plays a crucial role in the progression of human immunological disorders. Objectives. The aim of the study was to evaluate the effects of oridonin (ORD) on proliferation, inflammation and apoptosis in interleukin 4 (IL-4)-stimulated human bronchial epithelial (16HBE) cells. Materials and methods. Proliferation was assessed using a 5-Bromo-2-deoxyuridine (BrdU) assay, while acridine orange (AO), ethidium bromide (EB), propidium iodide, and 4',6-diamidino-2-phenylindole (DAPI) measured apoptosis. The protein expression levels of apoptosis-associated speck-like protein containing a C-terminal caspase recruitment domain (ASC), cleaved caspase-1, and nucleotide-binding domain and leucine-rich repeat protein 3 (NLRP3) were detected with western blot. Results. The results established that IL-4 stimulation markedly decreased (p < 0.05) the proliferation of 16HBE cells, while the administration of ORD increased their proliferation. Apoptosis and DNA damage were enhanced in the IL-4-stimulated group, whereas ORD exhibited anti-apoptotic activity. Moreover, the treatment with ORD significantly reduced (p < 0.05) the IL-4-induced expression of cleaved caspase-1, ASC and NLRP3 proteins. Conclusions. The findings suggest that NLRP3 is a direct target for ORD-mediated anti-inflammatory actions in injured 16HBE cells. Therefore, ORD may be a novel therapy against NLRP3-related disorders, including pediatric asthma (PA). [ABSTRACT FROM AUTHOR]

BackgroundPrior observational research has indicated a potential link between pediatric asthma and united airways disease (UAD). However, these findings could be subject to confounding factors and reverse causation. Therefore, our study utilizes Mendelian randomization (MR) method to further investigate the causal relationship between pediatric asthma and UAD.MethodsWe conducted a comprehensive two-sample Mendelian randomization (MR) analysis to investigate the association between pediatric asthma and seven groups of UAD, including chronic sinusitis, chronic rhinitis, nasopharyngitis and pharyngitis, chronic diseases of tonsils and adenoids, chronic laryngitis and laryngotracheitis, chronic bronchitis, bronchiectasis, chronic obstructive pulmonary disease (COPD). The present study employed a range of methods for two-sample MR analysis, including inverse variance weighted (IVW), MR-Egger regression, Simple mode, weighted median, and weighted models. The conclusion of the MR analysis primarily relies on the IVW results, while other analytical methods are utilized as supplementary evidence to ensure result robustness in this MR analysis. And sensitivity analyses were conducted, including heterogeneity test, horizontal pleiotropy test, MR-PRESSO test, and leave-one-out analysis to validate the results.ResultsThe results of the MR analysis indicate significant causal effects of pediatric asthma on chronic rhinitis, nasopharyngitis and pharyngitis (IVW: OR = 1.15, 95%CI: 1.05–1.26, p-value = 0.003), chronic diseases of tonsils and adenoids (IVW: OR = 1.07, 95%CI: 1.00–1.15, p-value = 0.038), chronic bronchitis (IVW: OR = 1.51, 95%CI: 1.42–1.62, p-value

Background: The “September epidemic” is a well-described phenomenon of increased pediatric asthma-related health care utilization from August to September each year. The coronavirus disease 2019 (COVID-19) pandemic has brought about significant changes in health care utilization, warranting an investigation into its impact on the September epidemic. Objective: Our aim was to identify the impact of COVID-19 in asthma-related health care utilization, specifically in the September epidemic. Methods: Our study involved a retrospective analysis of data from a Children's Hospital in New York City. We compared the change in asthma-related health care utilization during August and September 2020 with the average change in utilization during the same period in 2017-2019 and 2021-2022. Stratified analyses based on age and sex were conducted by using chi-square tests to determine variations in health care utilization. Results: During September 2020, there was a marked reduction in emergency department (ED) visits related to asthma, with only a 6% rise from the preceding month. This stands in contrast to the observed increases from 89% to 193% in the other years studied (P < .05 for all). This pattern was seen in both sexes and in children under 13 years old (P < .05). No significant variation was found for those older than 13 years (P > .05). Conclusions: Despite an overall reduction in health care utilization over the first year of the COVID-19 pandemic, the decline in ED visits related to asthma during the September epidemic was significantly more pronounced. These results suggest that there may be remediable risk factors contributing to the September epidemic that can be used to guide future interventions for managing pediatric asthma.

Objective To investigate the distribution characteristics of inhaled allergens in children with allergic rhinitis (AR) and asthma in Chongqing. Methods A cross-sectional study was conducted on 9 420 children with AR and asthma who underwent inhaled allergen skin prick test (SPT) in our department from January 2021 to September 2022 in Chongqing.According to the clinical diagnosis, these children were divided into the AR group (n=2 217) and the asthma group (n=7 023).Chi-square test was used to compare the detection rate of inhaled allergen SPT in 2 groups of children and the difference in the detection rate of inhaled allergen SPT between the 2 groups in terms of gender, age group and season, respectively. Results The detection rate of inhaled allergen SPT was 71.6% in the AR group and 57.9% in the asthma group (Chi-square=132.664, P < 0.001).The primary inhalant allergens in the 2 groups were dust mites (65.4%, 50.3%), house dust mites (65.0%, 50.4%), cockroach (10.2%, 7.9%), cat hair (8.3%, 6.0%), and corn pollen (6.5%, 6.1%), and children accepted test mainly had dual (57.1%/54.7%) and triple (22.2%/20.8%) inhaled allergens.In the AR group, the detection rate of inhaled allergens was higher in boys than that in girls (Chi-square=7.011, P=0.008), and the gender difference only appeared in the asthma group for the detection rate of cockroach (Chi-square=21.671, P < 0.001).In the AR group, the highest detection rates for dust mites and house dust mites happened in summer, while the highest detection rates for duck hair happened in spring; In the asthma group, the summer witnessed the highest detection rates for dust mites and house dust mites and the spring experienced the highest detection rates for corn, birch pollen and dog hair.The detection rate of inhaled allergens in children with AR and asthma was increased with age, and the detection rate of inhaled allergens in the AR group aged 1~10 years was higher than that in the asthma group of the same age group. Conclusion The inhaled allergens of children with AR and asthma in Chongqing are mainly from indoor sources.AR is dominated by perennial inhaled allergens compared with asthma, and the trends of the distribution for inhaled allergens in AR and asthma were similar.

Abstract Background Human rhinoviruses (HRVs) infection is a common cause of exacerbations in pediatric patients with asthma. However, the effects of corticosteroids on HRV-induced exacerbations in pediatric asthma are unknown. We conducted a prospective observational study to determine the viral pathogens in school-age pediatric inpatients with asthma exacerbations. We assessed the effects of maintenance inhaled corticosteroids (ICS) on the detection rates of HRV species and treatment periods of systemic corticosteroids during exacerbations on pulmonary lung function after exacerbations. Methods Nasopharyngeal samples and clinical information were collected from 59 patients with asthma exacerbations between April 2018 and March 2020. Pulmonary function tests were carried out 3 months after exacerbations in 18 HRV-positive patients. Changes in forced expiratory volume in 1 second (FEV1)% predicted from baseline in a stable state were compared according to the treatment periods of systemic corticosteroids. Results Fifty-four samples collected from hospitalized patients were analyzed, and viral pathogens were identified in 45 patients (83.3%) using multiplex PCR assay. HRV-A, −B, and -C were detected in 16 (29.6%), one (1.9%), and 16 (29.6%) patients, respectively. The detection rates of HRV-C were lower in the ICS-treated group compared with those in the ICS-untreated group (p = 0.01), whereas maintenance ICS treatment did not affect the detection rate for viral pathogens in total and HRV-A. Changes in FEV1% predicted in patients treated with systemic corticosteroids for 6–8 days (n = 10; median, 4.90%) were higher than those in patients treated for 3–5 days (n = 8; median, − 10.25%) (p = 0.0085). Conclusions Maintenance ICS reduced the detection rates of HRV (mainly HRV-C) in school-age inpatients with asthma exacerbations, and the treatment periods of systemic corticosteroids during exacerbations affected lung function after HRV-induced exacerbations. The protective effects of corticosteroids on virus-induced asthma exacerbations may be dependent upon the types of viral pathogen.

Background: In the emergency department (ED), prompt administration of systemic corticosteroids for pediatric asthma exacerbations decreases hospital admission rates. However, there is sparse evidence for whether earlier administration of systemic corticosteroids by emergency medical services (EMS) clinicians, prior to ED arrival, further improves pediatric asthma outcomes. Methods: Early Administration of Steroids in the Ambulance Setting: An Observational Design Trial is a multicenter, observational, nonrandomized stepped‐wedge design study with seven participating EMS agencies who adopted an oral systemic corticosteroid (OCS) into their protocols for pediatric asthma treatment. Using univariate analyses and multivariable mixed‐effects models, we compared hospital admission rates for pediatric asthma patients ages 2–18 years before and after the introduction of a prehospital OCS and for those who did and did not receive a systemic corticosteroid from EMS. Results: A total of 834 patients were included, 21% of whom received a systemic corticosteroid from EMS. EMS administration of systemic corticosteroids increased after the introduction of an OCS from 14.7% to 28.1% (p < 0.001). However, there was no significant difference between hospital admission rates and ED length of stay before and after the introduction of OCS or between patients who did and did not receive a systemic corticosteroid from EMS. Mixed‐effects models revealed that age 14–18 years (coefficient −0.83, p = 0.002), EMS administration of magnesium (coefficient 1.22, p = 0.04), and initial EMS respiratory severity score (coefficient 0.40, p < 0.001) were significantly associated with hospital admission. Conclusions: In this multicenter study, the addition of an OCS into EMS agency protocols for pediatric asthma exacerbations significantly increased systemic corticosteroid administration but did not significantly decrease hospital admission rates. As overall EMS systemic corticosteroid administration rates were low, further work is required to understand optimal implementation of EMS protocol changes to better assess potential benefits to patients.

Objective: To develop and validate a predictive algorithm that identifies pediatric patients at risk of asthma-related emergencies, and to test whether algorithm performance can be improved in an external site via local retraining. Methods: In a retrospective cohort at the first site, data from 26 008 patients with asthma aged 2-18 years (2012-2017) were used to develop a lasso-regularized logistic regression model predicting emergency department visits for asthma within one year of a primary care encounter, known as the Asthma Emergency Risk (AER) score. Internal validation was conducted on 8634 patient encounters from 2018. External validation of the AER score was conducted using 1313 pediatric patient encounters from a second site during 2018. The AER score components were then reweighted using logistic regression using data from the second site to improve local model performance. Prediction intervals (PI) were constructed via 10 000 bootstrapped samples. Results: At the first site, the AER score had a cross-validated area under the receiver operating characteristic curve (AUROC) of 0.768 (95% PI: 0.745-0.790) during model training and an AUROC of 0.769 in the 2018 internal validation dataset (p = 0.959). When applied without modification to the second site, the AER score had an AUROC of 0.684 (95% PI: 0.624-0.742). After local refitting, the cross-validated AUROC improved to 0.737 (95% PI: 0.676-0.794; p = 0.037 as compared to initial AUROC). Conclusions: The AER score demonstrated strong internal validity, but external validity was dependent on reweighting model components to reflect local data characteristics at the external site.

Objective: The length of hospital stay (LOS) is a proxy of asthma exacerbation severity and healthcare cost. The study aims to estimate the effect of ambient air pollution on pediatric asthma LOS in the Bronx, NY. Methods: A total of 1,920 children admitted to the hospital in Bronx, NY due to asthma during 2017-2019 period were included in the study. Demographic and clinical parameters were obtained from medical records. Daily ozone (O3) and fine particulate matter (PM2.5) measurements were obtained from local air quality networks. Poisson regression adjusting for gender, age, weight status, respiratory infections including influenza, and ambient temperature was applied to determine whether there was an association of air pollution with length of hospital stay. Results: The mean LOS varied by age, sex, weight status, influenza vaccination status, respiratory viral panel (RVP) results, asthma controller use, and asthma classification. After controlling for these factors in Poisson regression, the mean LOS increased up to 10.62% (95%CI: 0.78-21.41; p = 0.03) for an increase of 10 μg/m³ of PM2.5 exposure on admission day, and 3.90% (95%CI = 0.06-7.88; p = 0.05) for an increase of 10 ppbv of O3 concentration during the previous day. Conclusion: Ambient particulate and ozone pollution is associated with lengthier hospital stays for pediatric asthma, potentially indicating more severe asthma exacerbations. [ABSTRACT FROM AUTHOR]

Objective: The objective of this study was to examine the impact of long-term medium to high-dose inhaled budesonide on bone mineral density in children with asthma. Methods: We conducted a cross-sectional study in children aged 7-17 years with asthma, who received long-term (≥2 years), medium to high-dose inhaled budesonide (≥400μg/day in 6-11 years old; ≥800 μg/day in >11 years old). We measured bone mineral density (BMD) using dual-energy X-ray absorptiometry and compared it with reference Indian normative values. Results: Thirty-five children with moderate to severe asthma receiving long-term medium to high-dose inhaled budesonide, were included in the study. We found a significantly low lumbar-spine BMD in the study population compared to reference Indian values (p-value 0.002). Eight cases had short stature. Despite the adjustment for height-age in these short-stature cases, lumbar-spine BMD remained significantly low in the study population (p-value 0.020). No significant difference was found in 25-hydroxy vitamin D levels between subjects with "low BMD" and "BMD z-score > -2". Conclusions: The findings of this study suggest that long-term medium to high-dose inhaled budesonide treatment in children with asthma is associated with decreased BMD. However, further investigation with a larger sample size is necessary to confirm this relationship. [ABSTRACT FROM AUTHOR]

- Abstract
Childhood asthma is a common and serious chronic lung disease. Mobile health (mHealth) technologies may assist clinical providers, caregivers, and children in managing pediatric asthma. This study evaluated the Nemours app, an mHealth application. We examined: a) frequency of data access by providers and feature use by caregivers (parents/legal guardians) of 5–11-year-old children diagnosed with asthma and b) whether utilization was related to benefits. Nine providers (allergists/pulmonologists) and 80 patient-families (caregiver/child dyads) participated. Two-years of retrospective data were obtained for asthma control, in-person urgent healthcare utilization, and app utilization. Six-months of prospective data included asthma control, in-person urgent healthcare utilization, app utilization, surveys, and health literacy screeners. Providers (56%) accessed app data and caregivers (61%) utilized the app. Caregiver use of messaging feature predicted gains in health literacy scores (b =.44, p =.041), suggesting app use may offer some educational benefits. Implementation of strategies that support app engagement and utilization may help to maximize intended benefits. [ABSTRACT FROM AUTHOR]

Introduction: We aimed to evaluate the longitudinal relationships, both at between- and within-person levels, that adherence to inhaled corticosteroid-based maintenance treatment and inhalation technique present with symptom control, exacerbations, and health-related quality of life (HRQoL) in children and adolescents with asthma.Methods: Participants (6–14 years old) from the ARCA (Asthma Research in Children and Adolescents) cohort—a prospective, multicenter, observational study (NCT04480242)—were followed for a period from 6 months to 5 years via computer-assisted telephone interviews and a smartphone application. The Medication Intake Survey–Asthma (MIS-A) was administered to assess the implementation stage of adherence, and the Inhalation Technique Questionnaire (InTeQ) was used to assess the five key steps when using an inhaler. Symptom control was measured with the Asthma Control Questionnaire (ACQ), and HRQL was measured with the EQ-5D and the Patient-Reported Outcomes Measurement Information System–Pediatric Asthma Impact Scale (PROMIS-PAIS). Multilevel longitudinal mixed models were constructed separately with symptom control, exacerbation occurrence, EQ-5D, and PROMIS-PAIS as the dependent variables.Results: Of the 360 participants enrolled, 303 (1,203 interviews) were included in the symptom control and exacerbation analyses, 265 (732) in the EQ-5D, and 215 (617) in the PROMIS-PAIS. Around 60% of participants were male subjects, and most of them underwent maintenance treatment with inhaled corticosteroids plus long-acting β-agonists in a fixed dose (73.3%). Within-person variability was 83.6% for asthma control, 98.6% for exacerbations, 36.4% for EQ-5D, and 49.1% for PROMIS-PAIS. At the within-person level, patients with higher adherence had better symptom control (p = 0.002) and HRQoL over time (p = 0.016). Patients with a better inhalation technique reported worse HRQoL simultaneously (p = 0.012), but they showed better HRQoL in future assessments (p = 0.012). The frequency of reliever use was associated with symptom control (p < 0.001), exacerbation occurrence (p < 0.001), and HRQoL (p = 0.042); and boys were more likely to present better symptom control and HRQoL than girls.Conclusion: Our results confirm longitudinal associations at the within-person level of the two indicators of quality use of inhalers: for adherence to maintenance treatment with symptom control and HRQoL, and for the inhalation technique with HRQoL. Although treatment adherence was shown to be excellent, a third of the participants reported a suboptimal inhalation technique, highlighting the need for actions for improving asthma management of the pediatric population.

Abstract Background Pediatric asthma has been identified by regulators, clinicians, clinical trial sponsors, and caregivers as an area in need of novel fit-for-purpose clinical outcome assessments (COAs) developed in accordance with the U.S. Food and Drug Administration’s (FDA’s) regulatory guidance for evaluating clinical benefit in treatment trials. To address this gap, the Patient-Reported Outcome (PRO) Consortium’s Pediatric Asthma Working Group has continued development of 2 COAs to assess asthma signs and symptoms in pediatric asthma clinical trials to support efficacy endpoints: a PRO measure, the Pediatric Asthma Diary—Child (PAD-C) for children 8–11 years old (y.o.) and an observer-reported outcome measure, the Pediatric Asthma Diary-Observer (PAD—O) for caregivers of children 4–11 y.o. This qualitative research aimed to generate evidence regarding the content validity of the PAD-C and PAD-O. Methods Semi-structured combined concept elicitation and cognitive interviews were conducted with a diverse sample of U.S. participants (15 children 8–11 y.o. and 30 caregivers of children 4–11 y.o.). All children had clinician-diagnosed mild to severe asthma. Interviews explored the experience of pediatric asthma and assessed the understanding and relevance of both measures. Interviews were conducted across 3 iterative rounds to allow for modifications. Results Concept elicitation findings demonstrated that the core sign/symptom and impact concepts assessed in the PAD-C (cough, hard to breathe, out of breath, wheezing, chest tightness, and nighttime awakenings/symptoms) and PAD-O (cough, difficulty breathing, short of breath, wheezing, and nighttime awakenings/signs) correspond to those most frequently reported by participants; concept saturation was achieved. All PAD-C and PAD-O instructions and core items were well understood and considered relevant by most participants. Feedback from participants, the Pediatric Asthma Working Group, advisory panel, and FDA supported modifications to the measures, including addition of 1 new item to both measures and removal of 1 caregiver item. Conclusions Findings provide strong support for the content validity of both measures. The cross-sectional measurement properties of both measures and their user experience and feasibility in electronic format will be assessed in a future quantitative pilot study with qualitative exit interviews, intended to support the reliability, construct validity, final content, and, ultimately, FDA qualification of the measures.

This article briefly reviewed the effects of MT on children aged 5– 11 years old and adolescents with asthma from previous studies, specified its functional target towards asthma symptoms, and sorted out the design and investigation of selected research. Medline/PubMed, Embase, SportDis-cus, Cochrane Library, Teacher Reference Centre, Web of Science, Academic Search Complete, PsycARTICLES, and Scopus were queried for experimental and observational studies published between 1990 and 2021. Then, researchers showed that MT lessened patients’ asthma symptoms, improved medication compliance, pulmonary function, and quality of life, and helped children and their parents manage anxiety and depression. This article may serve as a reference for clinical research for pediatric asthma therapies and lay the foundation for future research on MT and its clinical practice.Keywords: pediatric asthma, music therapy, breath exercise, sing and play the wind instruments

Abstract Background Bronchial asthma is a global health problem that negatively affects the quality of life (QOL) of both children and their caregivers. However, there is a paucity of data regarding the impact of QOL on asthma severity in the pediatric population. Therefore, we aimed to examine the effect of health-related QOL of children with asthma and their caregivers on the level of asthma control and the degree of asthma severity. Results At enrollment, thirty asthmatic children and their caregivers completed the study. The standardized Arabic versions of the Pediatric Asthma Quality of Life Questionnaire (PAQLQ) and the Pediatric Asthma Caregiver’s Quality of Life Questionnaire (PACQLQ) were fulfilled by the asthmatic patients and their caregivers, respectively. Asthma control and severity were assessed using Global Initiative for Asthma guidelines and asthma severity scores. The relations between QOL and the other study parameters including asthma severity were examined which revealed that poor QOL of both asthmatic children and their caregivers was associated with frequent asthma-related hospital admissions (p = 0.046, 0.011). In addition, significant associations were found between symptoms, activity domains of PAQLQ score, and asthma control test score (p = 0.019,0.039). Furthermore, both QOL questionnaires’ total scores correlated strongly with asthma severity scores (p

Although sociodemographic risk factors are associated with parental depression among children with asthma, the contribution of these factors to caregiver depression in free-to-access universal healthcare settings is unknown.Methods: The association between childhood asthma and parental antidepressant use was investigated in a Danish nationwide cohort of children aged 2– 17 years that redeemed inhaled corticosteroids in 2015. The odds of antidepressant use were estimated in comparison to control families that were matched 1:1 on the number of siblings, residence, income, and education.Results: Among the families of 28,595 children with actively treated asthma, 12% of mothers and 6.2% of fathers were on antidepressant therapy, compared to 9.3% and 5.3% in controls (p< 0.001). Paediatric asthma was associated with increased odds of parental antidepressant use (OR 1.29 (1.23– 1.35)), even after adjusting for parental asthma. Poor asthma control, but not higher asthma severity, was associated with higher odds of antidepressant use (1.43 (1.31– 1.56)). Compared with the controls, families with two or more children with asthma had higher OR (1.42 (1.29– 1.56)) than those with a single child (OR 1.27 (1.21– 1.34)). Low socioeconomic status was associated with parental antidepressant use.Conclusion: Caregiver depression in a Danish cohort is more prevalent among mothers than among fathers and is associated with poor asthma control in children. Antidepressant use among caregivers was associated with total family asthma burden and was independent of socioeconomic status.Keywords: pediatric asthma, mental health, quality of life, pharmacoepidemiology

BackgroundCollection of patient-reported data has been demonstrated to improve asthma outcomes. One method to collect information is through the electronic patient portal. In practice, patient portal use in pediatrics and, specifically for asthma management, has had low uptake.ObjectiveTo understand parental/caregiver experience of pediatric asthma care management, and perceptions of the use of patient portal questionnaires before the clinic visit.MethodsWe conducted semi-structured interviews with caregivers of children 5-11 years old with asthma in the University of California, Los Angeles (UCLA) Health System. We included patient portal "users" (n = 20) and "non-users" (n = 5). Interview questions were developed based on clinic visit workflow with a focus on perceived usefulness and ease of use to complete pediatric asthma questionnaires in the patient portal before the visit. Interviews were audio-recorded, transcribed, and codes were generated from themes using constant comparative analysis.ResultsWe identified eight themes related to caregiver-physician communication, perception of portal questionnaires, facilitators, and barriers to portal questionnaire use. A salient finding was that caregivers considered the portal questionnaire as a tool to be integrated into the visit to facilitate a conversation about their child's asthma. Caregiver portal-based questionnaire use was more likely if the ongoing data entered was accessible to caregivers to track and update, and if caregivers were reassured the clinicians would use questionnaire responses during the visit.ConclusionCaregivers of children with asthma are more likely to complete a patient portal intake questionnaire before the visit if they trust their responses will be used during the visit to inform care.

Background: Exposure to air pollution is associated with acute pediatric asthma exacerbations, including reduced lung function, rescue medication usage, and increased symptoms; however, most studies are limited in investigating longitudinal changes in these acute effects. This study aims to investigate the effects of daily air pollution exposure on acute pediatric asthma exacerbation risk using a repeated-measures design. Methods: We conducted a panel study of 40 children aged 8−16 years with moderate-to-severe asthma. We deployed the Biomedical REAI-Time Health Evaluation (BREATHE) Kit developed in the Los Angeles PRISMS Center to continuously monitor personal exposure to particulate matter of aerodynamic diameter < 2.5 µm (PM2.5), relative humidity and temperature, geolocation (GPS), and asthma outcomes including lung function, medication use, and symptoms for 14 days. Hourly ambient (PM2.5, nitrogen dioxide (NO2), ozone (O3)) and traffic-related (nitrogen oxides (NOx) and PM2.5) air pollution exposures were modeled based on location. We used mixed-effects models to examine the association of same day and lagged (up to 2 days) exposures with daily changes in % predicted forced expiratory volume in 1 s (FEV1) and % predicted peak expiratory flow (PEF), count of rescue inhaler puffs, and symptoms. Results: Participants were on average 12.0 years old (range: 8.4−16.8) with mean (SD) morning %predicted FEV1 of 67.9% (17.3%) and PEF of 69.1% (18.4%) and 1.4 (3.5) puffs per day of rescue inhaler use. Participants reported chest tightness, wheeze, trouble breathing, and cough symptoms on 36.4%, 17.5%, 32.3%, and 42.9%, respectively (n = 217 person-days). One SD increase in previous day O3 exposure was associated with reduced morning (beta [95% CI]: −4.11 [−6.86, −1.36]), evening (−2.65 [−5.19, −0.10]) and daily average %predicted FEV1 (−3.45 [−6.42, −0.47]). Daily (lag 0) exposure to traffic-related PM2.5 exposure was associated with reduced morning %predicted PEF (−3.97 [−7.69, −0.26]) and greater odds of “feeling scared of trouble breathing” symptom (odds ratio [95% CI]: 1.83 [1.03, 3.24]). Exposure to ambient O3, NOx, and NO was significantly associated with increased rescue inhaler use (rate ratio [95% CI]: O3 1.52 [1.02, 2.27], NOx 1.61 [1.23, 2.11], NO 1.80 [1.37, 2.35]). Conclusions: We found significant associations of air pollution exposure with lung function, rescue inhaler use, and “feeling scared of trouble breathing.” Our study demonstrates the potential of informatics and wearable sensor technologies at collecting highly resolved, contextual, and personal exposure data for understanding acute pediatric asthma triggers.

BackgroundAsthma is a heterogeneous disease. Clinical blood parameters differ by race/ethnicity and are used to distinguish asthma subtypes and inform therapies. Differences in subtypes may explain population-specific trends in asthma outcomes. However, these differences in racial/ethnic minority pediatric populations are unclear.ObjectiveWe investigated the association of blood parameters and asthma subtypes with asthma outcomes and examined population-specific eligibility for biologic therapies in minority pediatric populations.MethodsUsing data from 2 asthma case-control studies of pediatric minority populations, we performed case-control (N = 3738) and case-only (N = 2743) logistic regressions to quantify the association of blood parameters and asthma subtypes with asthma outcomes. Heterogeneity of these associations was tested using an interaction term between race/ethnicity and each exposure. Differences in therapeutic eligibility were investigated using chi-square tests.ResultsRace/ethnicity modified the association between total IgE and asthma exacerbations. Elevated IgE level was associated with worse asthma outcomes in Puerto Ricans. Allergic asthma was associated with worse outcomes in Mexican Americans, whereas eosinophilic asthma was associated with worse outcomes in Puerto Ricans. A lower proportion of Puerto Ricans met dosing criteria for allergic asthma-directed biologic therapy than other groups. A higher proportion of Puerto Ricans qualified for eosinophilic asthma-directed biologic therapy than African Americans.ConclusionsWe found population-specific associations between blood parameters and asthma subtypes with asthma outcomes. Our findings suggest that eligibility for asthma biologic therapies differs across pediatric racial/ethnic populations. These findings call for more studies in diverse populations for equitable treatment of minority patients with asthma.

Background: Pediatric asthma has been identified by regulators, clinicians, clinical trial sponsors, and caregivers as an area in need of novel fit-for-purpose clinical outcome assessments (COAs) developed in accordance with the U.S. Food and Drug Administration's (FDA's) regulatory guidance for evaluating clinical benefit in treatment trials. To address this gap, the Patient-Reported Outcome (PRO) Consortium's Pediatric Asthma Working Group has continued development of 2 COAs to assess asthma signs and symptoms in pediatric asthma clinical trials to support efficacy endpoints: a PRO measure, the Pediatric Asthma Diary—Child (PAD-C) for children 8–11 years old (y.o.) and an observer-reported outcome measure, the Pediatric Asthma Diary-Observer (PAD—O) for caregivers of children 4–11 y.o. This qualitative research aimed to generate evidence regarding the content validity of the PAD-C and PAD-O. Methods: Semi-structured combined concept elicitation and cognitive interviews were conducted with a diverse sample of U.S. participants (15 children 8–11 y.o. and 30 caregivers of children 4–11 y.o.). All children had clinician-diagnosed mild to severe asthma. Interviews explored the experience of pediatric asthma and assessed the understanding and relevance of both measures. Interviews were conducted across 3 iterative rounds to allow for modifications. Results: Concept elicitation findings demonstrated that the core sign/symptom and impact concepts assessed in the PAD-C (cough, hard to breathe, out of breath, wheezing, chest tightness, and nighttime awakenings/symptoms) and PAD-O (cough, difficulty breathing, short of breath, wheezing, and nighttime awakenings/signs) correspond to those most frequently reported by participants; concept saturation was achieved. All PAD-C and PAD-O instructions and core items were well understood and considered relevant by most participants. Feedback from participants, the Pediatric Asthma Working Group, advisory panel, and FDA supported modifications to the measures, including addition of 1 new item to both measures and removal of 1 caregiver item. Conclusions: Findings provide strong support for the content validity of both measures. The cross-sectional measurement properties of both measures and their user experience and feasibility in electronic format will be assessed in a future quantitative pilot study with qualitative exit interviews, intended to support the reliability, construct validity, final content, and, ultimately, FDA qualification of the measures. Plain English summary: Pediatric asthma is one of the most common chronic diseases in children. However, there are problems of underdiagnosis, poor disease management, and undertreatment for many pediatric asthma patients, pressuring healthcare systems worldwide. Evaluating asthma symptoms is an important part of the development of treatments for pediatric asthma. However, there are few clinical outcome assessments (COAs) developed in line with regulatory guidance to directly assess symptom severity and evaluate the benefit of new treatments in children with asthma. In this study, we continued the development of the Pediatric Asthma Diary—Child (PAD-C) and the Pediatric Asthma Diary—Observer (PAD-O), according to regulatory guidance, to assess asthma signs and symptoms in children 4 through 11 years old and address this unmet need. The study aimed to explore the experience of pediatric asthma and assess how well-understood and relevant the measures are. Three rounds of qualitative interviews were conducted with 15 children 8 through 11 years old and 30 caregivers of children 4 through 11 years old with asthma. Results show that both measures are well-understood and assess the relevant and important aspects of pediatric asthma reported by children and caregivers. Findings provide evidence supporting the PAD-C and PAD-O as measures of symptom severity and their future use in pediatric asthma treatment trials. Further research is underway to evaluate their measurement properties and assess the user experience and feasibility of electronic completion, to ultimately support the PAD-C and PAD-O in an ongoing COA qualification process by the United States Food and Drug Administration.
