Exhaled Volatile Organic Compounds for Asthma Control Classification in Children with Moderate to Severe Asthma: Results from the SysPharmPediA Study.

RATIONALE: Early identification of children with poorly controlled asthma is imperative for optimizing treatment strategies. The analysis of exhaled volatile organic compounds (VOCs) is an emerging approach to identify prognostic and diagnostic biomarkers in pediatric asthma. OBJECTIVES: To assess the accuracy of gas chromatography-mass spectrometry based exhaled metabolite analysis to differentiate between controlled and uncontrolled pediatric asthma. METHODS: This study encompassed a discovery (SysPharmPediA) and validation phase (U-BIOPRED, PANDA). Firstly, exhaled VOCs that discriminated asthma control levels were identified. Subsequently, outcomes were validated in two independent cohorts. Patients were classified as controlled or uncontrolled, based on asthma control test scores and number of severe attacks in the past year. Additionally, potential of VOCs in predicting two or more future severe asthma attacks in SysPharmPediA was evaluated. MEASUREMENTS AND MAIN RESULTS: Complete data were available for 196 children (SysPharmPediA=100, U-BIOPRED=49, PANDA=47). In SysPharmPediA, after randomly splitting the population into training (n=51) and test sets (n=49), three compounds (acetophenone, ethylbenzene, and styrene) distinguished between uncontrolled and controlled asthmatics. The area under the receiver operating characteristic curve (AUROCC) for training and test sets were respectively: 0.83 (95% CI: 0.65-1.00) and 0.77 (95% CI: 0.58-0.96). Combinations of these VOCs resulted in AUROCCs of 0.74 ±0.06 (UBIOPRED) and 0.68 ±0.05 (PANDA). Attacks prediction tests, resulted in AUROCCs of 0.71 (95% CI 0.51-0.91) and 0.71 (95% CI 0.52-0.90) for training and test sets. CONCLUSIONS: Exhaled metabolites analysis might enable asthma control classification in children. This should stimulate further development of exhaled metabolites-based point-of-care tests in asthma.

Family adaptation in families of individuals with Down syndrome from 12 countries.

Our current understanding of adaptation in families of individuals with Down syndrome (DS) is based primarily on findings from studies focused on participants from a single country. Guided by the Resiliency Model of Family Stress, Adjustment, and Adaptation, the purpose of this cross-country investigation, which is part of a larger, mixed methods study, was twofold: (1) to compare family adaptation in 12 countries, and (2) to examine the relationships between family variables and family adaptation. The focus of this study is data collected in the 12 countries where at least 30 parents completed the survey. Descriptive statistics were generated, and mean family adaptation was modeled in terms of each predictor independently, controlling for an effect on covariates. A parsimonious composite model for mean family adaptation was adaptively generated. While there were cross-country differences, standardized family adaptation mean scores fell within the average range for all 12 countries. Key components of the guiding framework (i.e., family demands, family appraisal, family resources, and family problem-solving communication) were important predictors of family adaptation. More cross-country studies, as well as longitudinal studies, are needed to fully understand how culture and social determinants of health influence family adaptation in families of individuals with DS.

Exploring the burden of actinic keratoses through development of a patient decision aid: a mixed-methods study.

BACKGROUND: Actinic keratoses (AKs) are present on sun-exposed sites and are considered precursors of cutaneous squamous cell carcinoma. A better understanding of the experiences of patients with this condition may improve patient-provider relationships and guide the introduction of shared decision-making (SDM) to treatment decisions. OBJECTIVES: To develop a patient decision aid (PDA) for field treatment of multiple AKs in line with the International Patient Decision Aid Standards (IPDAS) by (i) characterizing the burden and lived experiences of patients with multiple AKs, (ii) understanding the decisional needs of patients requiring field treatment, and (iii) exploring clinician preferences regarding field treatment for multiple AKs. METHODS: This mixed-methods study followed the most up-to-date guidelines set out by the IPDAS collaboration; a voluntary body that aims to enhance the quality of PDAs by developing an evidence-based systematic process for the development of unbiased and effective PDAs. RESULTS: Multiple AKs have a psychosocial impact on patients. Patients feel supported through the integration of evidence-based information to guide SDM. CONCLUSIONS: We propose that the use of a PDA for multiple AKs provides a key role in supporting informed shared patient-provider decision-making and empowers patient involvement in their prospective treatment strategy.

Oropharyngeal Microbiota Clusters in Children with Asthma or Wheeze Associate with Allergy, Blood Transcriptomic Immune Pathways, and Exacerbation Risk.

Rationale: Children with preschool wheezing or school-age asthma are reported to have airway microbial imbalances. Objectives: To identify clusters in children with asthma or wheezing using oropharyngeal microbiota profiles. Methods: Oropharyngeal swabs from the U-BIOPRED (Unbiased Biomarkers for the Prediction of Respiratory Disease Outcomes) pediatric asthma or wheezing cohort were characterized using 16S ribosomal RNA gene sequencing, and unsupervised hierarchical clustering was performed on the Bray-Curtis ß-diversity. Enrichment scores of the Molecular Signatures Database hallmark gene sets were computed from the blood transcriptome using gene set variation analysis. Children with severe asthma or severe wheezing were followed up for 12-18 months, with assessment of the frequency of exacerbations. Measurements and Main Results: Oropharyngeal samples from 241 children (age range, 1-17 years; 40% female) revealed four taxa-driven clusters dominated by Streptococcus, Veillonella, Rothia, and Haemophilus. The clusters showed significant differences in atopic dermatitis, grass pollen sensitization, FEV1% predicted after salbutamol, and annual asthma exacerbation frequency during follow-up. The Veillonella cluster was the most allergic and included the highest percentage of children with two or more exacerbations per year during follow-up. The oropharyngeal clusters were different in the enrichment scores of TGF-ß (transforming growth factor-ß) (highest in the Veillonella cluster) and Wnt/ß-catenin signaling (highest in the Haemophilus cluster) transcriptomic pathways in blood (all q values <0.05). Conclusions: Analysis of the oropharyngeal microbiota of children with asthma or wheezing identified four clusters with distinct clinical characteristics (phenotypes) that associate with risk for exacerbation and transcriptomic pathways involved in airway remodeling. This suggests that further exploration of the oropharyngeal microbiota may lead to novel pathophysiologic insights and potentially new treatment approaches.

Stratification of asthma by lipidomic profiling of induced sputum supernatant.

BACKGROUND: Asthma is a chronic respiratory disease with significant heterogeneity in its clinical presentation and pathobiology. There is need for improved understanding of respiratory lipid metabolism in asthma patients and its relation to observable clinical features. OBJECTIVE: We performed a comprehensive, prospective, cross-sectional analysis of the lipid composition of induced sputum supernatant obtained from asthma patients with a range of disease severities, as well as from healthy controls. METHODS: Induced sputum supernatant was collected from 211 adults with asthma and 41 healthy individuals enrolled onto the U-BIOPRED (Unbiased Biomarkers for the Prediction of Respiratory Disease Outcomes) study. Sputum lipidomes were characterized by semiquantitative shotgun mass spectrometry and clustered using topologic data analysis to identify lipid phenotypes. RESULTS: Shotgun lipidomics of induced sputum supernatant revealed a spectrum of 9 molecular phenotypes, highlighting not just significant differences between the sputum lipidomes of asthma patients and healthy controls, but also within the asthma patient population. Matching clinical, pathobiologic, proteomic, and transcriptomic data helped inform the underlying disease processes. Sputum lipid phenotypes with higher levels of nonendogenous, cell-derived lipids were associated with significantly worse asthma severity, worse lung function, and elevated granulocyte counts. CONCLUSION: We propose a novel mechanism of increased lipid loading in the epithelial lining fluid of asthma patients resulting from the secretion of extracellular vesicles by granulocytic inflammatory cells, which could reduce the ability of pulmonary surfactant to lower surface tension in asthmatic small airways, as well as compromise its role as an immune regulator.

Parental entrustment of healthcare responsibilities to youth with chronic conditions: A concept analysis.

PURPOSE: Chronic health conditions impact nearly 40% of children in the United States, necessitating parents/caregivers to entrust healthcare responsibilities to youth aging into adulthood. Understanding the parental entrustment process may lead to tailored transition support; however, the concept lacks conceptual clarity, limiting its research and practical applications. DESIGN AND METHODS: Rodgers' evolutionary concept analysis method was used to clarify the parental entrustment of healthcare responsibilities to youth with chronic health conditions. PubMed, CINAHL, and PsycINFO databases were searched without date restrictions, including full-text, English-language, primary source articles related to parent-child healthcare transition preparation. Following title, abstract, and full-text screenings, data were analyzed using a hybrid thematic approach to identify antecedents, attributes, and consequences. RESULTS: Forty-three studies from August 1996 to September 2023 were identified. Antecedents encompass social cues and readiness factors, while attributes involve a) responsibility transfer, support, and facilitation, b) a dynamic process, c) balancing trust and fear, d) navigating conflict, and e) parental letting go. Consequences entail shifts in parental and adolescent roles. Parental entrustment is an iterative process wherein parents guide their maturing child through responsibility transfer via facilitation, support, conflict navigation, and trust building. CONCLUSION: The clarified concept underscores the role of parents/caregivers in empowering youth to manage their health. Introducing a working definition and conceptual model contributes to understanding the processes families navigate in the larger landscape of healthcare transition. PRACTICE IMPLICATIONS: This clarification holds implications for clinicians and policymakers, offering insights to enhance support and guidance for families navigating healthcare transition.

Barriers to and facilitators of accelerated BSN students' success: a scoping review with possible strategies for success.

OBJECTIVES: This scoping review aims to map the evidence on barriers and facilitators of success with accelerated BSN (ABSN) students with the inclusion of faculty perspectives. METHODS: We followed the scoping review methodology of the Joanna Briggs Institute for this review. The databases of CINAHL, PubMed, ProQuest, and Google Scholar were searched. RESULTS: The search resulted in 39 studies. The identified barriers were: Academic factors, non-academic factors, challenges faced by non-native English-speaking and ethnically diverse students, socialization struggles, and faculty perceptions. The facilitators identified were: Supportive environment and practices, benefits of ABSN program completion, students' background and life experiences, innovative learning strategies and school resources, and faculty perceptions. IMPLICATIONS FOR INTERNATIONAL AUDIENCE: Given the global nature of the ABSN program now, findings from this scoping review and the strategies for success addressed in discussion will inform ABSN faculty and program managers about helpful strategies to support students' needs.

Identifying and appraising outcome measures for severe asthma: a systematic review.

BACKGROUND: Valid outcome measures are imperative to evaluate treatment response, yet the suitability of existing end-points for severe asthma is unclear. This review aimed to identify outcome measures for severe asthma and appraise the quality of their measurement properties. METHODS: A literature search was performed to identify "candidate" outcome measures published between 2018 and 2020. A modified Delphi exercise was conducted to select "key" outcome measures within healthcare professional, patient, pharmaceutical and regulatory stakeholder groups. Initial validation studies for "key" measures were rated against modified quality criteria from COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN). The evidence was discussed at multi-stakeholder meetings to ratify "priority" outcome measures. Subsequently, four bibliographic databases were searched from inception to 20 July 2020 to identify development and validation studies for these end-points. Two reviewers screened records, extracted data, assessed their methodological quality and graded the evidence according to COSMIN. RESULTS: 96 outcome measures were identified as "candidates", 55 as "key" and 24 as "priority" for severe asthma, including clinical, healthcare utilisation, quality of life, asthma control and composite. 32 studies reported measurement properties of 17 "priority" end-points from the latter three domains. Only the Severe Asthma Questionnaire and Childhood Asthma Control Test were developed with input from severe asthma patients. The certainty of evidence was "low" to "very low" for most "priority" end-points across all measurement properties and none fulfilled all quality standards. CONCLUSIONS: Only two outcome measures had robust developmental data for severe asthma. This review informed development of core outcome measures sets for severe asthma.

Development of Core Outcome Measures sets for paediatric and adult Severe Asthma (COMSA).

BACKGROUND: Effectiveness studies with biological therapies for asthma lack standardised outcome measures. The COMSA (Core Outcome Measures sets for paediatric and adult Severe Asthma) Working Group sought to develop Core Outcome Measures (COM) sets to facilitate better synthesis of data and appraisal of biologics in paediatric and adult asthma clinical studies. METHODS: COMSA utilised a multi-stakeholder consensus process among patients with severe asthma, adult and paediatric clinicians, pharmaceutical representatives, and health regulators from across Europe. Evidence included a systematic review of development, validity and reliability of selected outcome measures plus a narrative review and a pan-European survey to better understand patients' and carers' views about outcome measures. It was discussed using a modified GRADE (Grading of Recommendations Assessment, Development and Evaluation) Evidence to Decision framework. Anonymous voting was conducted using predefined consensus criteria. RESULTS: Both adult and paediatric COM sets include forced expiratory volume in 1 s (FEV1) as z-scores, annual frequency of severe exacerbations and maintenance oral corticosteroid use. Additionally, the paediatric COM set includes the Paediatric Asthma Quality of Life Questionnaire and Asthma Control Test or Childhood Asthma Control Test, while the adult COM set includes the Severe Asthma Questionnaire and Asthma Control Questionnaire-6 (symptoms and rescue medication use reported separately). CONCLUSIONS: This patient-centred collaboration has produced two COM sets for paediatric and adult severe asthma. It is expected that they will inform the methodology of future clinical trials, enhance comparability of efficacy and effectiveness of biological therapies, and help assess their socioeconomic value. COMSA will inform definitions of non-response and response to biological therapy for severe asthma.

Global Initiative for Asthma Strategy 2021: Executive Summary and Rationale for Key Changes.

The Global Initiative for Asthma (GINA) Strategy Report provides clinicians with an annually updated evidence-based strategy for asthma management and prevention, which can be adapted for local circumstances (e.g., medication availability). This article summarizes key recommendations from GINA 2021, and the evidence underpinning recent changes. GINA recommends that asthma in adults and adolescents should not be treated solely with short-acting ß2-agonist (SABA), because of the risks of SABA-only treatment and SABA overuse, and evidence for benefit of inhaled corticosteroids (ICS). Large trials show that as-needed combination ICS-formoterol reduces severe exacerbations by ⩾60% in mild asthma compared with SABA alone, with similar exacerbation, symptom, lung function, and inflammatory outcomes as daily ICS plus as-needed SABA. Key changes in GINA 2021 include division of the treatment figure for adults and adolescents into two tracks. Track 1 (preferred) has low-dose ICS-formoterol as the reliever at all steps: as needed only in Steps 1-2 (mild asthma), and with daily maintenance ICS-formoterol (maintenance-and-reliever therapy, "MART") in Steps 3-5. Track 2 (alternative) has as-needed SABA across all steps, plus regular ICS (Step 2) or ICS-long-acting ß2-agonist (Steps 3-5). For adults with moderate-to-severe asthma, GINA makes additional recommendations in Step 5 for add-on long-acting muscarinic antagonists and azithromycin, with add-on biologic therapies for severe asthma. For children 6-11 years, new treatment options are added at Steps 3-4. Across all age groups and levels of severity, regular personalized assessment, treatment of modifiable risk factors, self-management education, skills training, appropriate medication adjustment, and review remain essential to optimize asthma outcomes.

Mapping atopic dermatitis and anti-IL-22 response signatures to type 2-low severe neutrophilic asthma.

BACKGROUND: Transcriptomic changes in patients who respond clinically to biological therapies may identify responses in other tissues or diseases. OBJECTIVE: We sought to determine whether a disease signature identified in atopic dermatitis (AD) is seen in adults with severe asthma and whether a transcriptomic signature for patients with AD who respond clinically to anti-IL-22 (fezakinumab [FZ]) is enriched in severe asthma. METHODS: An AD disease signature was obtained from analysis of differentially expressed genes between AD lesional and nonlesional skin biopsies. Differentially expressed genes from lesional skin from therapeutic superresponders before and after 12 weeks of FZ treatment defined the FZ-response signature. Gene set variation analysis was used to produce enrichment scores of AD and FZ-response signatures in the Unbiased Biomarkers for the Prediction of Respiratory Disease Outcomes asthma cohort. RESULTS: The AD disease signature (112 upregulated genes) encompassing inflammatory, T-cell, TH2, and TH17/TH22 pathways was enriched in the blood and sputum of patients with asthma with increasing severity. Patients with asthma with sputum neutrophilia and mixed granulocyte phenotypes were the most enriched (P < .05). The FZ-response signature (296 downregulated genes) was enriched in asthmatic blood (P < .05) and particularly in neutrophilic and mixed granulocytic sputum (P < .05). These data were confirmed in sputum of the Airway Disease Endotyping for Personalized Therapeutics cohort. IL-22 mRNA across tissues did not correlate with FZ-response enrichment scores, but this response signature correlated with TH22/IL-22 pathways. CONCLUSIONS: The FZ-response signature in AD identifies severe neutrophilic asthmatic patients as potential responders to FZ therapy. This approach will help identify patients for future asthma clinical trials of drugs used successfully in other chronic diseases.

Adaptation at the Family Level in Families of Individuals With Down Syndrome: A Scoping Review.

Down syndrome (DS) is a chromosomal disorder associated with intellectual and physical disabilities and has historically been viewed by health care providers through a negative lens when considering the effect the condition has on the individual, family, and community. The purpose of this scoping review was to provide an overview of recent research concerning adaptation in families of individuals with DS with a focus on family adaptation rather than individual or dyadic adaptation. Three literature indexes were searched from 2017 to 2022, with 41 articles included. Foci of the studies included strength/resilience, stress/coping, and negative/challenge. Thirteen studies reported using a family framework. Multiple methodological approaches and family measures were used in the studies and are outlined. Findings from this review show there has been a shift in focus when researching families of individuals with DS from a negative and challenging experience to one of strength and resilience.

Airway inflammation in severe asthmatics with acid gastro-oesophageal reflux.

The relationship between childhood asthma and gastro-oesophageal reflux (GOR) is contentious. Recent studies in adult asthmatics suggest that GOR is associated with worse control and differences in sputum proteomics related to epithelial integrity, systemic inflammation and host defence. We assessed 127 children with severe asthma undergoing bronchoscopy and pH study. There were no differences in asthma control or measures of airway inflammation or remodelling when those with acid GOR were compared with those without. These results suggest that acid GOR is not an important comorbidity in paediatric severe asthma.

Blood eosinophils in managing preschool wheeze: Lessons learnt from a proof-of-concept trial.

BACKGROUND: Management of preschool wheeze is based predominantly on symptom patterns. OBJECTIVE: To determine whether personalizing therapy using blood eosinophils or airway bacterial infection results in fewer attacks compared with standard care. METHODS: A proof-of-concept, randomized trial to investigate whether the prescription of inhaled corticosteroids (ICS) guided by blood eosinophils, or targeted antibiotics for airway bacterial infection, results in fewer unscheduled healthcare visits (UHCVs) compared with standard care. Children aged 1-5 years with ≥2 wheeze attacks in the previous year were categorized as episodic viral wheeze (EVW) or multiple trigger wheeze (MTW). The intervention group was prescribed ICS if blood eosinophils ≥3%, or targeted antibiotics if there is positive culture on induced sputum/cough swab. The control group received standard care. The primary outcome was UHCV at 4 months. RESULTS: 60 children, with a median age of 36.5 (range 14-61) months, were randomized. Median blood eosinophils were 5.2 (range 0-21)%, 27 of 60 (45%) children were atopic, and 8 of 60 (13%) had airway bacterial infection. There was no relationship between EVW, MTW and either blood eosinophils, atopic status or infection. 67% in each group were prescribed ICS. 15 of 30 control subjects and 16 of 30 patients in the intervention group had UHCV over 4 months (p = .8). The time to first UHCV was similar. 50% returned adherence monitors; in those, median ICS adherence was 67%. There were no differences in any parameter between those who did and did not have an UHCV. CONCLUSION: Clinical phenotype was unrelated to allergen sensitization or blood eosinophils. ICS treatment determined by blood eosinophils did not impact UHCV, but ICS adherence was poor.

Issues affecting young people with asthma through the transition period to adult care.

Asthma is among the most common medical conditions affecting children and young people, with adolescence a recognised period of increased risk, overrepresented in analyses examining recent increasing asthma mortality rates. Asthma may change significantly during this period and management also occurs in the context of patients seeking increased autonomy and self-governance whilst navigating increasing academic and social demands. A number of disease factors can destabilise asthma during adolescence including: increased rates of anaphylaxis, anxiety, depression, obesity, and, in females, an emerging resistance to corticosteroids and the pro-inflammatory effects of oestrogen. Patient factors such as smoking, vaping, poor symptom recognition, treatment non-adherence and variable engagement with health services contribute to difficult to treat asthma. Significant deficiencies in the current approach to transition have been identified by a recent EAACI task force, and subsequent asthma-specific recommendations, published in 2020 provide an important framework moving forward. As with other chronic conditions, effective transition programmes plan ahead, engage with adolescents and their families to identify the patients' management priorities and the current challenges they are experiencing with treatment. Transition needs may vary significantly across asthma patients and for more complex asthma may include dedicated transition clinics involving multidisciplinary care requiring input including, amongst others, allergy and immunology, psychological medicine, respiratory physicians and scientists and nurse specialists. Across different global regions, barriers to treatment may vary but need to be elicited and an individualised approach taken to optimising asthma care which is sustainable within the local adult healthcare system.

The 'number needed to treat' metric: a further marker of the impact of COVID-19 on malignant melanomas.

We comment on a previous article, describing the number needed to treat metric as a further marker on the impact of COVID-19 on treatment of malignant melanomas.

Recurrent Severe Preschool Wheeze: From Prespecified Diagnostic Labels to Underlying Endotypes.

Rationale: Preschool wheezing is heterogeneous, but the underlying mechanisms are poorly understood.Objectives: To investigate lower airway inflammation and infection in preschool children with different clinical diagnoses undergoing elective bronchoscopy and BAL.Methods: We recruited 136 children aged 1-5 years (105 with recurrent severe wheeze [RSW]; 31 with nonwheezing respiratory disease [NWRD]). Children with RSW were assigned as having episodic viral wheeze (EVW) or multiple-trigger wheeze (MTW). We compared lower airway inflammation and infection in different clinical diagnoses and undertook data-driven analyses to determine clusters of pathophysiological features, and we investigated their relationships with prespecified diagnostic labels.Measurements and Main Results: Blood eosinophil counts and percentages and allergic sensitization were significantly higher in children with RSW than in children with a NWRD. Blood neutrophil counts and percentages, BAL eosinophil and neutrophil percentages, and positive bacterial culture and virus detection rates were similar between groups. However, pathogen distribution differed significantly, with higher detection of rhinovirus in children with RSW and higher detection of Moraxella in sensitized children with RSW. Children with EVW and children with MTW did not differ in terms of blood or BAL-sample inflammation, or bacteria or virus detection. The Partition around Medoids algorithm revealed four clusters of pathophysiological features: 1) atopic (17.9%), 2) nonatopic with a low infection rate and high use of inhaled corticosteroids (31.3%), 3) nonatopic with a high infection rate (23.1%), and 4) nonatopic with a low infection rate and no use of inhaled corticosteroids (27.6%). Cluster allocation differed significantly between the RSW and NWRD groups (RSW was evenly distributed across clusters, and 60% of the NWRD group was assigned to cluster 4; P < 0.001). There was no difference in cluster membership between the EVW and MTW groups. Cluster 1 was dominated by Moraxella detection (P = 0.04), and cluster 3 was dominated by Haemophilus or Staphylococcus or Streptococcus detection (P = 0.02).Conclusions: We identified four clusters of severe preschool wheeze, which were distinguished by using sensitization, peripheral eosinophilia, lower airway neutrophilia, and bacteriology.

An academic-practice partnership during COVID-19 pandemic: Transitioning from a clinical to virtual fellowship.

AIMS: Discuss the needed modifications that occurred to the academic-practice oncology partnership during the COVID-19 pandemic. BACKGROUND: To meet the workforce needs of nurses who care for adults with cancer, an academic-practice partnership was created in 2016. The University of North Carolina at Chapel Hill School of Nursing, North Carolina Cancer Hospital and UNC Lineberger Comprehensive Cancer Center collaborated to provide structured clinical and didactic practice experiences for undergraduate nursing students interested in oncology nursing. With COVID-19, nursing students were not permitted to be in the clinical setting. DESIGN: Discursive paper. METHOD: An innovative and collaborative partnership created reflective and interactive activities. The majority of the learning activities were created at the revised Bloom's taxonomy level of application or higher, with some encompassing multiple levels. Students engaged in a variety of meaningful experiences requiring multiple learning processes that promoted professional development in the interpersonal and critical thinking domains. CONCLUSIONS: Despite the challenges of COVID-19, the delivery of oncology nurse fellowship was successful because of innovative virtual strategies. RELEVANCE TO CLINICAL PRACTICE: Our academic-practice partnership allowed the nursing students to develop their interpersonal and critical thinking skills without entering the clinical site. This is an approach encouraged by the authors for other schools of nursing. This manuscript is submitted as a Special Issue Discursive Article, and thus, the authors declare that an EQUATOR Checklist has not been used.

Safety of live attenuated influenza vaccine (LAIV) in children with moderate to severe asthma.

BACKGROUND: Live attenuated influenza vaccine (LAIV) is recommended for annual influenza vaccination in children from age 2 years. However, some guidelines recommend against its use in children with asthma or recurrent wheeze due to concerns over its potential to induce wheezing. OBJECTIVE: We sought to assess the safety of LAIV in children with moderate to severe asthma, and in preschool children with recurrent wheeze. METHODS: Prospective, multicenter, open-label, phase IV intervention study in 14 specialist UK clinics. LAIV was administered under medical supervision, with follow-up of asthma symptoms 72 hours and 4 weeks late, using validated questionnaires. RESULTS: A total of 478 young people (median, 9.3; range, 2-18 years) with physician-diagnosed asthma or recurrent wheeze were recruited, including 208 (44%) prescribed high-dose inhaled corticosteroids and 122 (31%) with severe asthma. There was no significant change in asthma symptoms in the 4 weeks after administration (median change, 0; P = .26, McNemar test), with no impact of level of baseline asthma control/symptoms in predicting either a worsening of asthma or exacerbation after LAIV using a regression model. A total of 47 subjects (14.7%; 95% CI, 11%-19.1%) reported a severe asthma exacerbation in the 4 weeks after immunization, requiring a short course of systemic corticosteroids; in 4 cases, this occurred within 72 hours of vaccination. No association with asthma severity, baseline lung function, or asthma control was identified. CONCLUSIONS: LAIV appears to be well tolerated in the vast majority of children with asthma or recurrent wheeze, including those whose asthma is categorized as severe or poorly controlled.
