Global impact of asthma on children and adolescents' daily lives: the room to breathe survey

Asthma and Participation: A Scoping Review

Asthma is a widespread pediatric chronic disease, but there is limited understanding of its impact on participation (other than physical activity) and the conceptualization of participation. We conducted a scoping review to explore the evidence on the relationship between pediatric asthma and participation in several domains of occupation outlined in the Occupational Therapy Practice Framework 4th Edition. A structured literature search was implemented in PubMed/MEDLINE, Elsevier EMBASE, CINAHL, SCOPUS, Clarivate Web of Science Core Collection, and APA PsycINFO. Data were extracted by occupational domain and analyzed using a stoplight categorization. Of the 3444 identified articles, 10 met inclusion criteria, five of which were categorized as green (addressing specific occupational activities). No article explicitly defined participation. Asthma's influence on nonphysical activity occupations remains unclear. Future research must clarify both the meaning and measures that best capture participation, and further explore the relationship between asthma and participation.

Psychometric evaluation of an electronic Asthma Symptom Diary for young children

BACKGROUND

Patient-reported outcome measures that facilitate self-report by children are needed to reduce the bias of proxy report. We previously developed an electronic Pediatric Asthma Symptom Diary (ePASD) to assess the severity of daily asthma symptoms and proximal impacts in children aged 6-11 years with mild to severe asthma. The ePASD, administered via a digital application with visuals, sounds, and text, is uniquely designed to minimize the importance of reading skills on children's ability to self-report accurately. Here, we describe the ePASD's psychometric properties.

METHODS

Ninety-one children aged 6-11 years with mild to severe asthma and their caregivers participated in 2 study visits, which consisted of training on the provisioned device and completing asthma-specific clinical outcome assessment (COA) questionnaires. The children self-completed the ePASD at home twice daily for 8 consecutive days. The scoring of the ePASD was guided by factor analyses, inter-item correlations, and internal consistencies. Reliability, discriminating ability, construct validity, and responsiveness were evaluated for ePASD items and candidate scores.

RESULTS

All COAs included in the study-the ePASD, Asthma Control Questionnaire (ACQ), Childhood Asthma Control Test, Pediatric Asthma Quality of Life Questionnaire-Standardized (PAQLQ[S]), and global ratings-demonstrated that the children exhibited few asthma-related symptoms and impacts at all timepoints, and consequently, showed little change over time. Internal consistencies (all Cronbach's alphas ≥ 0.52) and test-retest reliabilities (all intraclass correlation coefficients ≥ 0.60) were largely satisfactory. Patterns of convergent and divergent correlations supported the construct validity of ePASD scores. The ePASD symptom scores correlated moderately to strongly with PAQLQ(S) Symptom scores (all correlations ≥ - 0.46) and with ACQ scores (all correlations ≥ 0.42), as predicted. Evidence of the discriminating ability of ePASD items and composite scores was demonstrated by known-groups analyses.

CONCLUSIONS

The ePASD is a reliable and valid measure of asthma symptoms and proximal impacts in children aged 6-11 years with mild, moderate, or severe asthma. These results lay the psychometric groundwork for use of the ePASD in future clinical trials for the management of pediatric asthma. An ongoing pediatric asthma treatment trial is anticipated to provide evidence of the ePASD's responsiveness to change.

Exercise-Induced Bronchoconstriction Among Adolescent Athletes With Asthma: A Systematic Review

Exercise-induced bronchoconstriction (EIB) is a concern that frequently affects athletes and regular exercisers. The main objective of this systematic review is to study recently published literature that evaluated the risk of EIB among adolescent athletes with asthma. PubMed, Web of Science, Science Direct, EBSCO, SCOPUS, Wiley, and Cochrane Library were searched. Study articles were screened by title and abstract using Rayyan QCRI then a full-text assessment was implemented. A total of ten studies with 3129 adolescent athletic subjects were included in this review. The prevalence of EIB ranged from 2.1% to 61%. Most studies have demonstrated that athletes in their adolescence suffer from EIB, which requires regular management. Two studies have reported that low-income communities and humidity levels are risk factors for EIB. We found that EIB is frequent among adolescent athletes. The prevalence varies between countries due to different social and environmental factors.

Bullying and lifetime asthma among children and adolescents in the United States

PURPOSE

To examine the association of experiencing bullying within the past year with the prevalence of lifetime childhood asthma in US children and adolescents; and whether this associations vary with sex of the child and select socioeconomic indicators.

METHODS

We performed secondary analysis of data from the 2018 National Survey of Children's Health participants aged 6 to 17 years (n=19,766). We used log-binomial regression to examine the association between bullying and lifetime childhood asthma before and after controlling for select covariates. We also tested interactions of bullying with sex and select socioeconomic indicators.

RESULTS

Children who experience bullying have a significantly increased probability of having asthma in adjusted analyses. The probability of childhood asthma increased with the frequency of bullying with PRs starting at 1.28 (95%CI:1.06, 1.55) for children bullied 1-2 times per year to 1.59 (95%:1.22, 2.09) for those being bullied at least 4 times per month. This association did not differ with sex of the child and select socioeconomic indicators.

CONCLUSION

We found that children who experienced bullying had a greater probability of having asthma relative to those who never experienced bullying. These finding highlight the impact of psychosocial stressors on asthma as a nontraditional trigger in children with asthma.

[Patient expectations in asthma care]

Asthma, a common chronic disease characterized by variable levels of severity, requires patient-centered management to achieve the best health outcomes. Studies have highlighted the gap between consensus management recommendations and patient goals, which represent a potential source of therapeutic wandering and of poor compliance. Patient expectations are continually evolving and are dependent on knowledge, feelings and individual experience. From this perspective, listening carefully to patients and caregivers makes it easier to exchange views and define common goals. The active participation of patients at all levels of decision-making and transmission of information may improve asthma control and other quality of life parameters.

Management of Intermittent and Persistent Asthma in Adolescent and High School Athletes

Asthma is the most common chronic condition during childhood and adolescence, affecting an estimated 8% of children and youngsters below 18 years in the United States and the United Kingdom. In adolescent athletes, asthma-like symptoms may represent a common consequence of regular sport practice. Asthma in young athletes poses several challenges, including the ambiguity of definitions and diagnosis of asthma resulting from exercise-induced symptoms, the best pharmacological treatments, and the nonpharmacological options for the management of disease and the challenges inherent to this age group. At a time when the regular practice of sports is increasingly being recommended for a healthy living, the support network around the young athletes is crucial to reduce the impact of asthma on their physical and emotional well-being. In this review, we examine the main issues around the definitions and clinical differentiations of asthma in young sport athletes. We discuss best practice approaches to improve the adherence to the clinical management, including nonpharmacological strategies directed at the family and trainers of athlete adolescents.

Influence of social support on asthma self-management in adolescents

OBJECTIVE

Adolescents with asthma are influenced by peers and family. The objective was to better understand family social support and test its association with medication adherence, asthma control, and Emergency Department (ED) use.

METHODS

This study is a cross-sectional secondary data analysis from a randomized controlled trial with urban adolescents from three U.S. cities. Participants (12-20 years old) with asthma completed the Perceived Family Support Scale (PFS) and Horne's Medication Adherence Report Scale (MARS). Data from both tools were classified into 2 categories- high and low (< 25th percentile) perceived family support and high (total score >10) and low medication adherence, respectively. Chi-square statistic and logistic regression were used for analysis.

RESULTS

Of the 371 participants, the majority were young (96% ≤ 17 years), African American or Bi-racial (85%), and Medicaid-insured (72%); over one-third had maternal family history of asthma. Among those on a controller medication (n = 270), only 37% reported its use ≥8 days over 2 weeks. Asthma control was poor with 50% categorized "not well controlled," 34% "very poorly controlled." Participants responded positively to most social support items. One item, providing and receiving social support to and from family members, was less often positively reported. Low medication adherence was significantly associated with lower perceived social support (p = 0.018).

CONCLUSION

This study underscores the importance of family social support in understanding the extent of adolescents' self-management, particularly medication adherence.

Empowering children and young people who have asthma

Asthma is the most common chronic condition of childhood. In this review, we discuss an overview of strategies to empower children and young people with asthma. The key aspects of empowerment are to enable shared decision making and self-management, and help children minimise the impact of asthma on their life. The evidence behind these strategies is either sparse or heterogenous, and it is difficult to identify which interventions are most likely to improve clinical outcomes. Wider determinants of health, in high-resource and low-resource settings, can be disempowering for children with asthma. New approaches to technology could help empower young people with asthma and other chronic health conditions.

Longitudinal Relationships between Asthma-Specific Quality of Life and Asthma Control in Children; The Influence of Chronic Rhinitis

Managing pediatric asthma includes optimizing both asthma control and asthma-specific quality of life (QoL). However, it is unclear to what extent asthma-specific QoL is related to asthma control or other clinical characteristics over time. The aims of this study were to assess in children longitudinally: (1) the association between asthma control and asthma-specific QoL and (2) the relationship between clinical characteristics and asthma-specific QoL. In a 12-month prospective study, asthma-specific QoL, asthma control, dynamic lung function indices, fractional exhaled nitric oxide, the occurrence of exacerbations, and the use of rescue medication were assessed every 2 months. Associations between the clinical characteristics and asthma-specific QoL were analyzed using linear mixed models. At baseline, the QoL symptom score was worse in children with asthma and concomitant chronic rhinitis compared to asthmatic children without chronic rhinitis. An improvement of asthma control was longitudinally associated with an increase in asthma-specific QoL (p-value < 0.01). An increased use of β₂-agonists, the occurrence of wheezing episodes in the year before the study, the occurrence of an asthma exacerbation in the 2 months prior to a clinical visit, and a deterioration of lung function correlated significantly with a decrease in the Pediatric Asthma Quality of Life Questionnaire (PAQLQ) total score (p-values ≤ 0.01). Chronic rhinitis did not correlate with changes in the PAQLQ score over 1 year. The conclusion was that asthma control and asthma-specific QoL were longitudinally associated, but were not mutually interchangeable. The presence of chronic rhinitis at baseline did influence QoL symptom scores. β₂-agonist use and exacerbations before and during the study were inversely related to the asthma-specific QoL over time.

School-based self-management interventions for asthma in children and adolescents: a mixed methods systematic review

BACKGROUND

Asthma is a common respiratory condition in children that is characterised by symptoms including wheeze, shortness of breath, chest tightness, and cough. Children with asthma may be able to manage their condition more effectively by improving inhaler technique, and by recognising and responding to symptoms. Schools offer a potentially supportive environment for delivering interventions aimed at improving self-management skills among children. The educational ethos aligns with skill and knowledge acquisition and makes it easier to reach children with asthma who do not regularly engage with primary care. Given the multi-faceted nature of self-management interventions, there is a need to understand the combination of intervention features that are associated with successful delivery of asthma self-management programmes.

OBJECTIVES

This review has two primary objectives.• To identify the intervention features that are aligned with successful intervention implementation.• To assess effectiveness of school-based interventions provided to improve asthma self-management among children.We addressed the first objective by performing qualitative comparative analysis (QCA), a synthesis method described in depth later, of process evaluation studies to identify the combination of intervention components and processes that are aligned with successful intervention implementation.We pursued the second objective by undertaking meta-analyses of outcomes reported by outcome evaluation studies. We explored the link between how well an intervention is implemented and its effectiveness by using separate models, as well as by undertaking additional subgroup analyses.

SEARCH METHODS

We searched the Cochrane Airways Trials Register for randomised studies. To identify eligible process evaluation studies, we searched MEDLINE, Embase, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycINFO, the Cochrane Database of Systematic Reviews (CDSR), Web of Knowledge, the Database of Promoting Health Effectiveness Reviews (DoPHER), the Database of Abstracts of Reviews of Effects (DARE), the International Biography of Social Science (IBSS), Bibliomap, Health Technology Assessment (HTA), Applied Social Sciences Index and Abstracts (ASSIA), and Sociological Abstracts (SocAbs). We conducted the latest search on 28 August 2017.

SELECTION CRITERIA

Participants were school-aged children with asthma who received the intervention in school. Interventions were eligible if their purpose was to help children improve management of their asthma by increasing knowledge, enhancing skills, or changing behaviour. Studies relevant to our first objective could be based on an experimental or quasi-experimental design and could use qualitative or quantitative methods of data collection. For the second objective we included randomised controlled trials (RCTs) where children were allocated individually or in clusters (e.g. classrooms or schools) to self-management interventions or no intervention control.

DATA COLLECTION AND ANALYSIS

We used qualitative comparative analysis (QCA) to identify intervention features that lead to successful implementation of asthma self-management interventions. We measured implementation success by reviewing reports of attrition, intervention dosage, and treatment adherence, irrespective of effects of the interventions.To measure the effects of interventions, we combined data from eligible studies for our primary outcomes: admission to hospital, emergency department (ED) visits, absence from school, and days of restricted activity due to asthma symptoms. Secondary outcomes included unplanned visits to healthcare providers, daytime and night-time symptoms, use of reliever therapies, and health-related quality of life as measured by the Asthma Quality of Life Questionnaire (AQLQ).

MAIN RESULTS

We included 55 studies in the review. Thirty-three studies in 14,174 children provided information for the QCA, and 33 RCTs in 12,623 children measured the effects of interventions. Eleven studies contributed to both the QCA and the analysis of effectiveness. Most studies were conducted in North America in socially disadvantaged populations. High school students were better represented among studies contributing to the QCA than in studies contributing to effectiveness evaluations, which more commonly included younger elementary and junior high school students. The interventions all attempted to improve knowledge of asthma, its triggers, and stressed the importance of regular practitioner review, although there was variation in how they were delivered.QCA results highlighted the importance of an intervention being theory driven, along with the importance of factors such as parent involvement, child satisfaction, and running the intervention outside the child's own time as drivers of successful implementation.Compared with no intervention, school-based self-management interventions probably reduce mean hospitalisations by an average of about 0.16 admissions per child over 12 months (SMD -0.19, 95% CI -0.35 to -0.04; 1873 participants; 6 studies, moderate certainty evidence). They may reduce the number of children who visit EDs from 7.5% to 5.4% over 12 months (OR 0.70, 95% CI 0.53 to 0.92; 3883 participants; 13 studies, low certainty evidence), and probably reduce unplanned visits to hospitals or primary care from 26% to 21% at 6 to 9 months (OR 0.74, 95% CI 0.60 to 0.90; 3490 participants; 5 studies, moderate certainty evidence). Self-management interventions probably reduce the number of days of restricted activity by just under half a day over a two-week period (MD 0.38 days 95% CI -0.41 to -0.18; 1852 participants; 3 studies, moderate certainty evidence). Effects of interventions on school absence are uncertain due to the variation between the results of the studies (MD 0.4 fewer school days missed per year with self-management (-1.25 to 0.45; 4609 participants; 10 studies, low certainty evidence). Evidence is insufficient to show whether the requirement for reliever medications is affected by these interventions (OR 0.52, 95% CI 0.15 to 1.81; 437 participants; 2 studies; very low-certainty evidence). Self-management interventions probably improve children's asthma-related quality of life by a small amount (MD 0.36 units higher on the Paediatric AQLQ(95% CI 0.06 to 0.64; 2587 participants; 7 studies, moderate certainty evidence).

AUTHORS' CONCLUSIONS

School-based asthma self-management interventions probably reduce hospital admission and may slightly reduce ED attendance, although their impact on school attendance could not be measured reliably. They may also reduce the number of days where children experience asthma symptoms, and probably lead to small improvements in asthma-related quality of life. Many of the studies tested the intervention in younger children from socially disadvantaged populations. Interventions that had a theoretical framework, engaged parents and were run outside of children's free time were associated with successful implementation.

Impact of Self-Efficacy on The Quality of Life of Children With Asthma and Their Caregivers

INTRODUCTION

Health-related quality of life is an important outcome measurement in the monitoring of asthma control. Self-efficacy is a determinant of self-management behaviors that can contribute to the improvement of asthma control and quality of life. Our objective was to analyze the relationship between self-efficacy and quality of life in children with asthma and their caregivers.

METHODS

We included 176 patients aged 6-14 years with asthma, and determined their level of self-efficacy according to three groups (low, medium and high levels). Each child and their main caregiver completed the PAQLQ and PACQLQ questionnaires, respectively.

RESULTS

PAQLQ range=1-7: 5.61±1.11; PACQLQ range=1-7: 5.42±1.35; self-efficacy range=0-60: low level 28.44±4.58; average level 37.41±1.7, and high level 47.50±5.5. Significant differences were observed in quality of life according to low-medium vs. high levels of self-efficacy. Specific related domains: PAQLQ emotions and PAQLQ symptoms with self-efficacy in problem-solving skills related to asthma and treatment self-efficacy; PACQLQ emotions with self-efficacy in problem-solving skills related to asthma.

CONCLUSIONS

A high level of self-efficacy is associated with a better quality of life for children and their caregivers. Based on these results, the measurement of self-efficacy could be incorporated in the assessment of educational interventions in self-management targeted at the quality of life of the patient and his or her family.

Neurokinin 1 receptor promotes rat airway smooth muscle cell migration in asthmatic airway remodelling by enhancing tubulin expression

Background

Airway remodelling is a major contributor to hyper-responsiveness leading to chronic asthma; however, the underlying mechanisms remain unclear. This study aimed to investigate the effects of a neurokinin 1 receptor (NK1R) antagonist (WIN62577) on the migration of airway smooth muscle cells (ASMCs) and the expression of NK1R and alpha-tubulin in airway remodelling using young rats with asthma.

Methods

Sprague-Dawley rats were randomly divided into a control group and airway remodelling group. Rats in the model group were stimulated with ovalbumin for 8 weeks. Primary ASMCs were cultured and purified from all rats, and then treated with different doses of WIN62577. The expression of NK1R and α-tubulin in ASMCs was assessed using immunofluorescence, real-time quantitative polymerase chain reaction, and western blotting. Changes in ASMC migration were detected by a transwell chamber assay.

Results

The transwell assay showed that the number of migrating ASMCs in the asthmatic airway remodelling group was significantly greater than that in the control group (P<0.01), which was inhibited by WIN62577 in a dose-dependent manner, with peak inhibition detected at 10^-8 mol/L. The mRNA and protein expression levels of NK1R and α-tubulin were significantly higher in the asthmatic airway remodelling group than in the control group (P<0.05 and P<0.01, respectively), and were significantly decreased after treatment with WIN62577 (P<0.01 and P<0.05, respectively).

Conclusions

NK1R antagonists may suppress ASMC migration in a rat model of airway remodelling by inhibiting tubulin expression, indicating a new potential target for the treatment and control of chronic asthma.

Demographic and medical factors affecting short-term changes in subjective evaluation of asthma control in adolescents

INTRODUCTION

Asthma control is an important measure of disease stabilization, which is linked to the treatment and lifestyle recommendations.

AIM

To assess the impact of selected factors on asthma control in adolescents, as assessed using the Asthma Control Test (ACT™).

MATERIAL AND METHODS

The prospective study included 100 asthma patients aged between 12 and 19. Asthma was assessed in three consecutive follow-up visits spaced 3 months apart, using the standardized ACT™ questionnaire.

RESULTS

Asthma was fully controlled (ACT score = 25 points) in more than half of the patients in all follow-up visits (53.0%, 54.0%, and 56.0%, respectively). More than one third of the participants scored between 20 and 24 points (37.0% vs. 39.0% vs. 40.0%). A minority of patients had uncontrolled asthma (scores below 20), and the group consistently diminished in subsequent visits (10% vs. 7% vs. 4%). Uncontrolled asthma was found significantly more often in female patients (33.33%; p < 0.001) and those living in rural areas (20.59%; p < 0.01). Treatment with a combination of inhaled corticosteroids (ICS) and LABAs was associated with worse asthma control (14.81%; p < 0.05). Better asthma control was found in patients with a family history of allergies (73.85% vs. 75.38% vs. 78.46%; p < 0.001) and in those with concurrent allergies (66.67% vs. 68.00% vs. 70.67%; p < 0.001).

CONCLUSIONS

Asthma control in adolescents differs by sex and residence. Concurrent allergies and family history of allergies improve asthma self-control in adolescents.

Spirometry monitoring in asthmatic children in Lombardy Region, Italy

OBJECTIVES

To evaluate the diagnostic and therapeutic approaches in a cohort of asthmatic children before and after starting drug therapy.

METHODS

Data were retrieved from administrative databases of the Lombardy Region. The study population was composed of 78 184 children born in the Lombardy Region in 2002 and followed until their 10th birthday.Children with at least one antiasthmatic drug prescription per year (with the exclusion of nebulised suspension/solution formulations) in 2 consecutive years and at least one antiasthmatic drug prescription after the fifth birthday were identified as potential asthmatics (PA).Each PA was monitored for a period starting from 12 months before and ending 24 months after the first prescription (index prescription, IP). During the monitoring period antiasthmatic drug prescriptions were analysed, as well as spirometry and/or specialist visits.

RESULTS

A total of 59 975 children (76.7%) received ≥1 prescription of antiasthmatic drugs in their first 10 years of life, and 4475 (5.7%) were identified as PAs. In all, 24% of PAs started with short-acting β2-agonists (SABA), 23% with inhaled corticosteroids (ICS) and 20% with SABA+ICS.A total of 33% of PAs had at least one prescription for specialist visit/spirometry: 11% before and 28% after the IP. The factors associated with a greater likelihood of receiving visit/spirometry prescriptions were local health unit of residence, age and high use of asthma drugs.

CONCLUSIONS

Despite international guideline recommendations, spirometry monitoring is still underused in asthmatic children, even in subjects who initiated pharmacological treatment and therefore need an airway function evaluation. Moreover, the choice of drug therapy appears not always rational, since one out of four children were commenced on ICS as monotherapy.

Social Functioning and Coping Strategies in Romanian and Moldavian Adolescents with Chronic Diseases

The present study aimed to explore the cultural differences in social functioning and coping strategies in chronically ill adolescents. One hundred sixty-eight chronically ill adolescents (45.8 % girls), age 11 to 17 years from Romania (N = 78) and Republic of Moldova (N = 90) were recruited. Participants filled in self-assessment measures for social functioning problems and coping strategies. Results indicated cross-cultural differences in the studied factors: Moldavian adolescents reported more social functioning problems and higher use of maladaptive coping strategies, while using less adaptive strategies than Romanian counterparts. The associations between social functioning and maladaptive coping strategies were stronger for Romanian than Moldavian adolescents. Further, various coping strategies acted as important predictors for social functioning in the two country samples. Findings suggest that, while the direction of the relation between coping and social functioning in chronically ill adolescents is cultural invariant, the importance played by specific coping strategies in determining social functioning varies by cultural context. Therefore, clinical interventions aimed at improving the social functioning of chronically ill adolescents should take into account the reality of their cultural setting.

Characterization of Stress in Low-Income, Inner-City Mothers of Children with Poorly Controlled Asthma

The goal of this longitudinal analysis was to characterize factors associated with the experience of life stress in low-income, inner-city mothers of minority children with high-risk asthma.Participants (n = 276) reported on family demographics, child asthma control and healthcare utilization, social support, contemporary life difficulties (housing, finances, violence exposure) measured by the validated Crisis in Family Systems scale, and daily stress. Latent growth curve modeling examined predictors of life stress across 12 months as a function of home and community difficulties, asthma-specific factors, and social support. Mothers were primarily single (73%), unemployed (55%), and living in extreme poverty with most (73%) reporting an annual family income <$20,000 (73%). The children were young (mean age = 5.59, SD = 2.17), African-American (96%), and had poorly controlled asthma (94%) at study enrollment. Higher daily stress was associated with financial difficulties, safety concerns in the home and community, and housing problems. Access to social support was consistently related to reduced stress. The only asthma-specific factor associated with life stress was healthcare utilization, with more emergency services for asthma related to higher daily stress. Findings underscore the clinical significance of assessing diverse home and community stressors and social support in low-income, inner-city caregivers of children with poorly controlled asthma.

Experiences of Daily Life Among Adolescents With Asthma - A Struggle With Ambivalence

OBJECTIVE

There is limited knowledge about how adolescents with asthma view their disease in daily life and how these views impact on management. The aim of this study was to describe experiences of daily life, with particular focus on thoughts, feelings and management of adolescents with asthma.

METHODS

In this qualitative study, data were obtained from 10 interviews with adolescents (aged 16-18 years) with asthma recruited from the Swedish population-based prospective birth cohort, BAMSE. Data were analysed through Systematic Text Condensation.

RESULTS

Experiences of daily life among adolescents with asthma were defined in four categories: Insight and understanding; Asthma not the focus of daily life; Being acknowledged and, Being affected by asthma symptoms. The adolescents had developed an insight into and understanding of their disease, but did not want asthma to be the focus of their daily lives. The adolescents wanted their asthma to be acknowledged, but not to the point that they were defined by their asthma. They reported having many asthma symptoms, especially during physical activity, but also described a desire to feel healthy, "normal" and like their peers.

CONCLUSIONS

Having asthma in adolescence involves several struggles with ambivalence between adapting socially, feeling healthy and managing one's asthma.

IMPLICATIONS IN CLINICAL PRACTICE

The provision of person-centred care may be one way to handle the ambivalence among adolescents with asthma and thereby help them to manage their asthma.

Adolescent flourishing in relation to having asthma: Results from a population-based cross-sectional study

OBJECTIVE

This study investigated parent report of adolescent behaviors and flourishing of adolescents with asthma from a nationwide sample.

METHODS

A secondary analysis of the 2011-2012 National Survey of Children's Health was conducted. There were 2,880 youth with asthma in our sample and 25,841 without asthma between 13 and 17 years of age. Analyses examined flourishing among adolescents with and without asthma and the impact of adolescent arguing, bullying, and mood difficulties on adolescent flourishing for adolescents with asthma, while controlling for sex, age, and race.

RESULTS

Findings indicated lower flourishing for youth with asthma compared to youth without asthma. Moreover, adolescents with asthma who experienced negative behaviors, such as arguing and bullying, and adolescents who were experiencing sad feelings had lower flourishing.

CONCLUSIONS

The results were consistent with literature, indicating that relatively poorer behavioral and emotional functioning is related to lower flourishing in adolescents with asthma. The results highlight the importance of screening for emotional functioning in adolescents and the need for further research to understand characteristics of adolescents related to their positive functioning.

Validation of asthma control questionnaire and risk factors affecting uncontrolled asthma among the Lebanese children's population

OBJECTIVES

To validate the Arabic version of the Asthma Control Test (ACT) in asthmatic children in Lebanon and identify risk factors that might affect asthma control in these children.

METHODS

This study, conducted between December 2015 and April 2016, included 300 children.

RESULTS

A high Cronbach's alpha was found for the full scale (0.959). The correlation factors between each item of the ACT scale and the whole scale ranged between 0.710 and 0.775(p < 0.001 for all items). Low mother's educational level as well as the history of asthma in the mother and the father would significantly increase the risk of uncontrolled asthma (p = 0.001; Beta = 1.862; p < 0.001; Beta = 3.534; p < 0.001; Beta = 1.885respectively). Cigarette smoking during breastfeeding and waterpipe smoking by the mother during pregnancy were both significantly associated with uncontrolled asthma (p = 0.005; Beta = 2.105 and p = 0.041; Beta = 2.325 respectively). The high mother's level of education was significantly associated with more asthma control (p = 0.008; Beta = -0.715).

CONCLUSION

The Arabic version of the asthma control questionnaire is a valid tool to use in pediatric patients in the Lebanese population to assess asthma control. Waterpipe smoking during pregnancy and cigarette smoking during breastfeeding, as well as the lower education level are risk factors for uncontrolled asthma. Spreading awareness among health care professionals, as well as reinforcing health education seem to be an important step toward a better asthma control.

Physicians' perceptions of mobile technology for enhancing asthma care for youth

This study assessed physicians' receptivity to using mobile technology as a strategy in patient care for adolescents with asthma. Understanding physicians' perceived barriers and benefits of integrating mobile technology in adolescents' asthma care and self-management is an initial step in enhancing overall patient and disease outcomes. We conducted in-depth interviews with second- and third-year pediatric residents and attending physicians who oversee pediatric residents in training (N = 27) at an academic medical center in the southeastern United States. We identified both benefits from and barriers to broader use of mobile technologies for improving asthma outcomes in adolescents. Resident physicians demonstrated greater readiness for integrating these technologies than did attending physicians. Prior to adoption of mobile technologies in the care of adolescent asthma patients, barriers to implementation should be understood. Prior to widespread adoption, such systems will need to be evaluated against traditional care for demonstration of patient outcomes that improve on the current situation.

Factors associated with quality of life in children with asthma living in Scotland

INTRODUCTION

Asthma affects children's quality of life (QoL) but factors associated with QoL are not well understood. Our hypothesis was that there are factors linked to QoL which are amenable to treatment or environmental modification.

METHODS

QoL was ascertained in a study designed to link environmental exposures to asthma outcomes. Univariate and multivariate analysis were used to determine which factors are associated with QoL.

RESULTS

There were 553 children with asthma where QoL was determined, mean age 10.3 and 312 (58%) were boys. The median QoL score was 5.9 (interquartile range 4.6, 6.8). In the multivariate model, asthma severity (as evidenced by British Thoracic Society, BTS, treatment step), smoking exposure, socioeconomic status and rhinitis were associated with the QoL score. QoL score was reduced by (i) 30% [95% confidence interval 20, 39] for those on BTS step 4 compared to BTS step 1 treatment (ii) 11% [2, 19] for children with ≥ two resident smokers with reference to no resident smokers (iii) 3% [1, 5] for each quintile difference in deprivation compared to the most affluent and (iv) 9% [4, 14] for children with rhinitis compared to no rhinitis.

CONCLUSIONS

The QoL for children with asthma in the UK is generally good. Clinicians caring children with asthma should consider routinely asking about smoke exposure and hayfever symptoms in addition to assessing asthma control.

Monitoring asthma in childhood: symptoms, exacerbations and quality of life

Monitoring asthma in children in clinical practice is primarily performed by reviewing disease activity (daytime and night-time symptoms, use of reliever medication, exacerbations requiring frequent use of reliever medication and urgent visits to the healthcare professional) and the impact of the disease on children's daily activities, including sports and play, in a clinical interview. In such an interview, most task force members also discuss adherence to maintenance therapy and the patients' (and parents') views and beliefs on the goals of treatment and the amount of treatment required to achieve those goals. Composite asthma control and quality of life measures, although potentially useful in research, have limited value in clinical practice because they have a short recall window and do not cover the entire spectrum of asthma control. Telemonitoring of children with asthma cannot replace face-to-face follow-up and monitoring because there is no evidence that it is associated with improved health outcomes.

Monitoring asthma in childhood

The goal of asthma treatment is to obtain clinical control and reduce future risks to the patient. However, to date there is limited evidence on how to monitor patients with asthma. Childhood asthma introduces specific challenges in terms of deciding what, when, how often, by whom and in whom different assessments of asthma should be performed. The age of the child, the fluctuating course of asthma severity, variability in clinical presentation, exacerbations, comorbidities, socioeconomic and psychosocial factors, and environmental exposures may all influence disease activity and, hence, monitoring strategies. These factors will be addressed in herein.

We identified large knowledge gaps in the effects of different monitoring strategies in children with asthma. Studies into monitoring strategies are urgently needed, preferably in collaborative paediatric studies across countries and healthcare systems.

Asthma control in children: Is it important and can we measure it?

The goal of asthma management is to achieve disease control. Poorly controlled asthma is associated with an increased number of days lost from school, exacerbations and days in hospital. Furthermore, children with uncontrolled asthma have more frequent contacts with the health-care system. Recent studies have added new information about the effects of poorly controlled asthma on a range of important, but less studied outcomes, including risk of obesity, daily physical activity, cardiovascular fitness, stress, concentration and focused attention, learning disabilities and risk of depression. From these studies it seems that poor asthma control may have a greater impact on the child than previously thought. This may have important long-term consequences for the child such as an increased risk of life-style associated diseases and poorer school performance. The level of control seems to be the most important determinant of these adverse effects and improvement in asthma control is associated with improvements in many of the outcomes. However, the improvement has to be maintained for a very long time (> 1 year). Accurate assessment of the level of asthma control is difficult. Various tools and scores have been developed. They are all based on various questionnaires, but their validation has been difficult because we have no golden standard to compare with. It seems as if the tests are most valuable when they suggest that the disease is poorly controlled because a large proportion of children in whom the tests suggest good asthma control may still have poorly controlled asthma when various objective outcomes are included in the assessment. A main reason for that seems to be that none of the tests accurately detects the child's adaptation in lifestyle. If you do not exercise you have fewer symptoms.

Stress and Quality of Life in Urban Caregivers of Children With Poorly Controlled Asthma: A Longitudinal Analysis

INTRODUCTION

The intent of this analysis was to examine the longitudinal effects of risk and protective factors on quality of life (QOL) in caregivers of minority children with asthma.

METHOD

Caregivers (n = 300) reported on demographics, child asthma characteristics, daily asthma caregiving stress, general life stress, social support, and QOL. Latent growth curve modeling examined changes in QOL across 12 months as a function of stress, asthma control, and social support.

RESULTS

Caregivers were primarily the biological mother (92%), single (71%), unemployed (55%), and living in poverty. Children were African American (96%), Medicaid eligible (92%), and had poorly controlled asthma (93%). Lower QOL was associated with higher life stress, greater asthma caregiving stress, and lower asthma control over time.

DISCUSSION

Findings underscore the importance of assessing objective and subjective measures of asthma burden and daily life stress in clinical encounters with urban, low-income caregivers of children with poorly controlled asthma.

Evaluating the Validity of an Automated Device for Asthma Monitoring for Adolescents: Correlational Design

BACKGROUND

Symptom monitoring is a cornerstone of asthma self-management. Conventional methods of symptom monitoring have fallen short in producing objective data and eliciting patients' consistent adherence, particularly in teen patients. We have recently developed an Automated Device for Asthma Monitoring (ADAM) using a consumer mobile device as a platform to facilitate continuous and objective symptom monitoring in adolescents in vivo.

OBJECTIVE

The objectives of the study were to evaluate the validity of the device using spirometer data, fractional exhaled nitric oxide (FeNO), existing measures of asthma symptoms/control and health care utilization data, and to examine the sensitivity and specificity of the device in discriminating asthma cases from nonasthma cases.

METHODS

A total of 84 teens (42 teens with a current asthma diagnosis; 42 without asthma) aged between 13 and 17 years participated in the study. All participants used ADAM for 7 consecutive days during which participants with asthma completed an asthma diary two times a day. ADAM recorded the frequency of coughing for 24 hours throughout the 7-day trial. Pearson correlation and multiple regression were used to examine the relationships between ADAM data and asthma control, quality of life, and health care utilization at the time of the 7-day trial and 3 months later. A receiver operating characteristic (ROC) curve analysis was conducted to examine sensitivity and specificity based on the area under the curve (AUC) as an indicator of the device's capacity to discriminate between asthma versus nonasthma cases.

RESULTS

ADAM data (cough counts) were negatively associated with forced expiratory volume in first second of expiration (FEV1) (r=-.26, P=.05), forced vital capacity (FVC) (r=-.31, P=.02), and overall asthma control (r=-.41, P=.009) and positively associated with daily activity limitation (r=.46, P=.01), nighttime (r=.40, P=.02) and daytime symptoms (r=.38, P=.02), and health care utilization (r=.61, P<.001). Device data were also a significant predictor of asthma control (β=-.48, P=.003), quality of life (β=-.55, P=.001), and health care utilization (β=.74, P=.004) after 3 months. The ROC curve analysis for the presence of asthma diagnosis had an AUC of 0.71 (95% CI 0.58-0.84), which was significantly different from chance (χ(2) 1=9.7, P=.002), indicating the device's discriminating capacity. The optimal cutoff value of the device was 0.56 with a sensitivity of 51.3% and a specificity of 72.7%.

CONCLUSIONS

This study demonstrates validity of ADAM as a symptom-monitoring device in teens with asthma. ADAM data reflect the current status of asthma control and predict asthma morbidity and quality of life for the near future. A monitoring device such as ADAM can increase patients' awareness of the patterns of cough for early detection of worsening asthma and has the potential for preventing serious and costly future consequences of asthma.

Associations of Pet Ownership with Wheezing and Lung Function in Childhood: Findings from a UK Birth Cohort

Background

Asthma is a heterogeneous condition and differential effects of pet ownership on non-atopic versus atopic asthma have been reported. The aim of this study was to investigate whether pet ownership during pregnancy and early childhood was associated with wheezing from birth to age 7 years and with lung function at age 8 years in a UK population-based birth cohort.

Methods

Data from the Avon Longitudinal Study of Parents and Children (ALSPAC) were used to investigate associations of pet ownership at six time-points from pregnancy to age 7 years with concurrent episodes of wheezing, wheezing trajectories (phenotypes) and lung function at age 8 years using logistic regression models adjusted for child’s sex, maternal history of asthma/atopy, maternal smoking during pregnancy, and family adversity.

Results

4,706 children had complete data on pet ownership and wheezing. From birth to age 7 years, cat ownership was associated with an overall 6% lower odds of wheezing (OR=0.94 (0.89-0.99)). Rabbit and rodent ownership was associated with 21% (OR=1.21 (1.12-1.31)) and 11% (OR=1.11 (1.02–1.21)) higher odds of wheezing, respectively, with strongest effects evident during infancy. Rabbit and rodent ownership was positively associated with a ‘persistent wheeze’ phenotype. Pet ownership was not associated with lung function at age 8 years, with the exception of positive associations of rodent and bird ownership with better lung function.

Conclusions

Cat ownership was associated with reduced risk, and rabbit and rodent ownership with increased risk, of wheezing during childhood. The mechanisms behind these differential effects warrant further investigation.

The impact of discussing exercise test results of young asthmatic children on adherence to maintenance medication

OBJECTIVE

Parents' awareness of their child's asthma may improve by discussing an exercise challenge test (ECT) result with them. We investigated the influence of discussing an ECT result with parents on adherence to inhaled maintenance medication, parental illness perceptions and medication beliefs in young asthmatic children.

METHODS

A total of 79 children, 4-7 years old and enrolled in our standard comprehensive asthma care program, performed an ECT to assess exercise induced bronchoconstriction (EIB). The result of the ECT was immediately discussed with the parents. Median medication adherence level was measured with electronic medication loggers from six weeks before the ECT till six weeks afterwards. Parental beliefs about medicines and illness perceptions were measured with the Beliefs about Medicines Questionnaire (BMQ) and the Brief Illness Perceptions Questionnaire (B-IPQ).

RESULTS

The median baseline adherence level was high (83%) and showed a small significant decline after the ECT. There was no significant difference in the decrease in median adherence level between the children with or without EIB. Most parents (82.1%) showed a positive necessity-concern ratio at baseline, as measured with the BMQ. There was no clinical relevant change in medication concerns and necessity scores or in illness perceptions.

CONCLUSION

Discussing ECT results with parents does not modify median adherence levels to inhaled maintenance medication nor medication beliefs of highly adherent young asthmatic children who are already enrolled in a comprehensive asthma care program.

Bullying in medically fragile youth: a review of risks, protective factors, and recommendations for medical providers

Bullying is a common child and adolescent phenomenon that has concurrent and long-term implications for victims' psychological, psychosomatic, social, and academic functioning. Youth with chronic illnesses are at increased risk for being bullied, but few studies have evaluated specific risk and protective factors for medically fragile youth. Despite recommendations by the American Academy of Pediatrics and the Society for Adolescent Medicine that pediatric health care providers should contribute to bullying prevention and intervention efforts, researchers also have yet to identify the best ways for providers to intervene with medically fragile youth. In this article, the authors review risk and protective factors for bullying among healthy samples. Then, the authors specifically address the ways in which these risk and protective factors are likely to apply to children with fragile medical conditions, and they provide summaries of extant bullying research for selected examples of medically fragile pediatric populations. Finally, the authors present recommendations for intervening with medically fragile youth and suggest several areas in which additional research is needed.

Monitoring asthma in children

The goal of asthma treatment is to obtain clinical control and reduce future risks to the patient. To reach this goal in children with asthma, ongoing monitoring is essential. While all components of asthma, such as symptoms, lung function, bronchial hyperresponsiveness and inflammation, may exist in various combinations in different individuals, to date there is limited evidence on how to integrate these for optimal monitoring of children with asthma. The aims of this ERS Task Force were to describe the current practise and give an overview of the best available evidence on how to monitor children with asthma. 22 clinical and research experts reviewed the literature. A modified Delphi method and four Task Force meetings were used to reach a consensus. This statement summarises the literature on monitoring children with asthma. Available tools for monitoring children with asthma, such as clinical tools, lung function, bronchial responsiveness and inflammatory markers, are described as are the ways in which they may be used in children with asthma. Management-related issues, comorbidities and environmental factors are summarised. Despite considerable interest in monitoring asthma in children, for many aspects of monitoring asthma in children there is a substantial lack of evidence.

A randomised dose-ranging study of tiotropium Respimat® in children with symptomatic asthma despite inhaled corticosteroids

BACKGROUND

A considerable number of children with asthma remain symptomatic despite treatment with inhaled corticosteroids, resulting in significant morbidity, reduced quality of life, increased healthcare costs and lost school days. The aim of our study was to assess the efficacy, safety and tolerability of once-daily tiotropium Respimat® 5 μg, 2.5 μg and 1.25 μg add-on to medium-dose inhaled corticosteroids, with or without a leukotriene modifier, in children aged 6-11 years with symptomatic asthma.

METHODS

In this Phase II, double-blind, placebo-controlled, incomplete-crossover, dose-ranging study, patients were randomised to receive three of the four treatments evaluated: once-daily tiotropium Respimat® 5 μg, 2.5 μg or 1.25 μg or placebo Respimat®, in the evening during the 12-week (three × 4-week) treatment period.

RESULTS

In total, 76, 74, 75 and 76 patients aged 6-11 years received tiotropium Respimat® 5 μg, 2.5 μg, 1.25 μg and placebo Respimat®, respectively. For the primary end point (peak forced expiratory volume in 1 second measured within 3 hours post-dosing), the adjusted mean responses with tiotropium Respimat® 5 μg (272 mL), 2.5 μg (290 mL) and 1.25 μg (261 mL) were significantly greater than with placebo Respimat® (185 mL; p = 0.0002, p < 0.0001 and p = 0.0011, respectively). The safety and tolerability of all doses of tiotropium Respimat® were comparable with those of placebo Respimat®, with no serious adverse events and no events leading to discontinuation.

CONCLUSIONS

Tiotropium Respimat® add-on to medium-dose inhaled corticosteroids, with or without a leukotriene modifier, was efficacious in paediatric patients with symptomatic asthma and had comparable safety and tolerability with placebo Respimat®.

Measuring health-related quality of life with the EQ-5D-Y instrument in children and adolescents with asthma

AIM

Asthma is one of the most common chronic paediatric diseases worldwide and affects different dimensions of health-related quality of life. This study tested the feasibility and convergent validity of using the EQ-5D-Y instrument on children and adolescents with asthma.

METHODS

A cross-sectional design was chosen, and children with asthma, aged from 8 to 16 years, were recruited from clinics in Stockholm, Sweden. To test convergent validity, the EQ-5D-Y instrument was combined with the Paediatric Quality of Life Questionnaire.

RESULTS

The EQ-5D-Y proved feasible as nearly 96% of the 94 respondents completed all items on the questionnaire. High and moderate correlations between the two instruments were found for the dimensions of 'doing usual activities' and 'activity limitations' and for 'having pain or discomfort' and 'symptoms'. The visual analogue scale of the ED-5D-Y correlated with the Paediatric Quality of Life Questionnaire total score and the self-rated health question. The dimensions on the EQ-5D-Y with most reported problems were 'usual activities', 'pain or discomfort' and 'worried, sad or unhappy'.

CONCLUSION

The EQ-5D-Y instrument seemed to provide feasibility and convergent validity for measuring health-related quality of life in children and adolescents with asthma.

Pet ownership is associated with increased risk of non-atopic asthma and reduced risk of atopy in childhood: findings from a UK birth cohort

BACKGROUND

Studies have shown an inverse association of pet ownership with allergy but inconclusive findings for asthma.

OBJECTIVE

To investigate whether pet ownership during pregnancy and childhood was associated with asthma and atopy at the age of 7 in a UK population-based birth cohort.

METHODS

Data from the Avon Longitudinal Study of Parents and Children (ALSPAC) were used to investigate associations of pet ownership at six time points from pregnancy to the age of 7 with asthma, atopy (grass, house dust mite, and cat skin prick test) and atopic vs. non-atopic asthma at the age of 7 using logistic regression models adjusted for child's sex, maternal history of asthma/atopy, maternal smoking during pregnancy, and family adversity.

RESULTS

A total of 3768 children had complete data on pet ownership, asthma, and atopy. Compared with non-ownership, continuous ownership of any pet (before and after the age of 3) was associated with 52% lower odds of atopic asthma [odds ratio (OR) 0.48, 95% CI 0.34-0.68]. Pet ownership tended to be associated with increased risk of non-atopic asthma, particularly rabbits (OR 1.61, 1.04-2.51) and rodents (OR 1.86, 1.15-3.01), comparing continuous vs. non-ownership. Pet ownership was consistently associated with lower odds of sensitization to grass, house dust mite, and cat allergens, but rodent ownership was associated with higher odds of sensitization to rodent allergen. Differential effects of pet ownership on atopic vs. non-atopic asthma were evident for all pet types.

CONCLUSIONS AND CLINICAL RELEVANCE

Pet ownership during pregnancy and childhood in this birth cohort was consistently associated with a reduced risk of aeroallergen sensitization and atopic asthma at the age of 7, but tended to be associated (particularly for rabbits and rodents) with an increased risk of non-atopic asthma. The opposing effects on atopy vs. non-atopic asthma might be considered by parents when they are deciding whether to acquire a pet.

The sensory profile of children with asthma

AIM

Sensory hypersensitivity is one expression of sensory processing disorders (SPD) and results from the inability to regulate an appropriate response to a sensory input in an adaptive manner. We explored the sensory processing profile of children with asthma, based on reports from parents.

METHODS

We studied 86 children between the ages of four and 11 years: 37 diagnosed with asthma and 49 healthy controls. The parents of all participants filled out the Short Sensory Profile (SSP) that measures the child's behavioural reactions to sensory stimuli in daily environments.

RESULTS

Sensory processing disorders were more prevalent among children with asthma (F7,71 = 4.16, p = 0.001; ή(2) = 0.29) than among healthy controls and were mainly reflected by hypersensitivity. While about 90% of the healthy children were reported to actively seek sensory stimuli, only 53% of the asthmatic children showed this trend. In the study group, 25.7% of the children's scores reflected abnormal sensory performance, compared with 0% of the controls (χ(2) =21.93; p < 0.001).

CONCLUSION

Children with asthma may suffer from SPD. Our finding supports previous reports that suggest that the central nervous system is involved in the pathogenesis of atopic conditions. The sensory profile of children with asthma should be evaluated and treated as required.

Disparities in assessments of asthma control between children, parents, and physicians

OBJECTIVE

Assessment of asthma control in children by physicians, patients and their parents was compared, assuming parents may underestimate symptoms in asthmatic children and exploring whether physicians tend to agree with them.

DESIGN

Asthma control perception was assessed in 4- to 11-year-old asthmatic children and their parents, using C-ACT, during 2011-2012. Pediatric pulmonologists used GINA guidelines for their assessment; pediatricians, not having spirometry, used the information given in addition to physical examination. The C-ACT scores given by the children and their parents were further analyzed separately, and compared with their physicians' assessment. Statistical methods, which also measured possible influence of different variables, included kappa, Chi-square, linear-by-linear association, McNemar test and logistic regression.

PATIENT SELECTION

The study comprised 354 parents and children aged 4-11 years with moderate-severe asthma; 129 (36.4%) were treated by 23 pediatricians; 225 (63.6%) by 11 pediatric pulmonologists.

RESULTS

The C-ACT was generally found valid in assessing asthma control (P < 0.001; κ 0.529; CI 0.441, 0.617) and showed that in 229/354 (53%) of children the asthma was uncontrolled. Nevertheless, of the 229 children who indicated their asthma was uncontrolled, 124 (54.1%) of their parents (κ 0.245; CI 0.15, 0.34) and 96 (41.9%) of their physicians believed it to be controlled (κ 0.331; 0.24, 0.43). Comparing the physician-child discordance vis-à-vis the parents, the significant difference was when 96/229 children (41.9%) and 34/126 parents (27.0%) indicated the asthma was uncontrolled while the physician determined it controlled (OR 1.95; 1.19, 3.24). There were no significant differences between pediatric pulmonologists and pediatricians.

CONCLUSIONS

In addition to increasing awareness of parents to symptoms in their asthmatic children, physicians should question the child appropriately, as well as using the children's responses to C-ACT as an information source for properly assessing asthma control.

Development of an International School Nurse Asthma Care Coordination Model

AIM

To identify and compare how school nurses in Reykjavik, Iceland and St. Paul, Minnesota coordinated care for youth with asthma (ages 10-18) and to develop an asthma school nurse care coordination model.

BACKGROUND

Little is known about how school nurses coordinate care for youth with asthma in different countries.

DESIGN

A qualitative descriptive study design using focus group data.

METHODS

Six focus groups with 32 school nurses were conducted in Reykjavik (n = 17) and St. Paul (n = 15) using the same protocol between September 2008 and January 2009. Descriptive content analytic and constant comparison strategies were used to categorize and compare how school nurses coordinated care, which resulted in the development of an International School Nurse Asthma Care Coordination Model.

FINDINGS

Participants in both countries spontaneously described a similar asthma care coordination process that involved information gathering, assessing risk for asthma episodes, prioritizing healthcare needs and anticipating and planning for student needs at the individual and school levels. This process informed how they individualized symptom management, case management and/or asthma education. School nurses played a pivotal part in collaborating with families, school and healthcare professionals to ensure quality care for youth with asthma.

CONCLUSIONS

Results indicate a high level of complexity in school nurses' approaches to asthma care coordination that were responsive to the diverse and changing needs of students in school settings. The conceptual model derived provides a framework for investigators to use in examining the asthma care coordination process of school nurses in other geographic locations.

Automated Cough Assessment on a Mobile Platform

The development of an Automated System for Asthma Monitoring (ADAM) is described. This consists of a consumer electronics mobile platform running a custom application. The application acquires an audio signal from an external user-worn microphone connected to the device analog-to-digital converter (microphone input). This signal is processed to determine the presence or absence of cough sounds. Symptom tallies and raw audio waveforms are recorded and made easily accessible for later review by a healthcare provider. The symptom detection algorithm is based upon standard speech recognition and machine learning paradigms and consists of an audio feature extraction step followed by a Hidden Markov Model based Viterbi decoder that has been trained on a large database of audio examples from a variety of subjects. Multiple Hidden Markov Model topologies and orders are studied. Performance of the recognizer is presented in terms of the sensitivity and the rate of false alarm as determined in a cross-validation test.

Are students with asthma at increased risk for being a victim of bullying in school or cyberspace? Findings from the 2011 Florida youth risk behavior survey

BACKGROUND

Adolescents with asthma are at risk for psychological and behavioral problems. The aim of this study was to determine whether high school students with asthma are at increased risk for bullying in school and cyberspace, and to explore the role of depressive symptoms in moderating this association.

METHODS

A secondary data analysis was completed with the 2011 Florida Youth Risk Behavior Survey. Participant included a random sample of adolescents in grades 9 through 12 who attended public high schools in Florida. Descriptive and inferential statistics were conducted using SPSS software.

RESULTS

We examined data from 6212 high school adolescents and found a significant relationship between current asthma and cyberbullying in adolescents. Of the sample diagnosed with asthma, 15.6% reported bullying and 17% cyberbullying (versus 10.2% and 11% of nonasthmatics). We further examined data using depressive symptoms as a mediating and moderating variable and found significance on all accounts.

CONCLUSIONS

Adolescents with asthma are at increased risk for being victims of bullying in school and cyberspace. Our findings suggest that adolescents with asthma who also report depressive symptoms are particularly at high risk for bullying than adolescents with asthma who did not report depressive symptoms. Efforts to increase education and decrease all types of bullying at the high school level for both students with and without asthma are warranted.

The development of an automated device for asthma monitoring for adolescents: methodologic approach and user acceptability

BACKGROUND

Many adolescents suffer serious asthma related morbidity that can be prevented by adequate self-management of the disease. The accurate symptom monitoring by patients is the most fundamental antecedent to effective asthma management. Nonetheless, the adequacy and effectiveness of current methods of symptom self-monitoring have been challenged due to the individuals' fallible symptom perception, poor adherence, and inadequate technique. Recognition of these limitations led to the development of an innovative device that can facilitate continuous and accurate monitoring of asthma symptoms with minimal disruption of daily routines, thus increasing acceptability to adolescents.

OBJECTIVE

The objectives of this study were to: (1) describe the development of a novel symptom monitoring device for teenagers (teens), and (2) assess their perspectives on the usability and acceptability of the device.

METHODS

Adolescents (13-17 years old) with and without asthma participated in the evolution of an automated device for asthma monitoring (ADAM), which comprised three phases, including development (Phase 1, n=37), validation/user acceptability (Phase 2, n=84), and post hoc validation (Phase 3, n=10). In Phase 1, symptom algorithms were identified based on the acoustic analysis of raw symptom sounds and programmed into a popular mobile system, the iPod. Phase 2 involved a 7 day trial of ADAM in vivo, and the evaluation of user acceptance using an acceptance survey and individual interviews. ADAM was further modified and enhanced in Phase 3.

RESULTS

Through ADAM, incoming audio data were digitized and processed in two steps involving the extraction of a sequence of descriptive feature vectors, and the processing of these sequences by a hidden Markov model-based Viterbi decoder to differentiate symptom sounds from background noise. The number and times of detected symptoms were stored and displayed in the device. The sensitivity (true positive) of the updated cough algorithm was 70% (21/30), and, on average, 2 coughs per hour were identified as false positive. ADAM also kept track of the their activity level throughout the day using the mobile system's built in accelerometer function. Overall, the device was well received by participants who perceived it as attractive, convenient, and helpful. The participants recognized the potential benefits of the device in asthma care, and were eager to use it for their asthma management.

CONCLUSIONS

ADAM can potentially automate daily symptom monitoring with minimal intrusiveness and maximal objectivity. The users' acceptance of the device based on its recognized convenience, user-friendliness, and usefulness in increasing symptom awareness underscores ADAM's potential to overcome the issues of symptom monitoring including poor adherence, inadequate technique, and poor symptom perception in adolescents. Further refinement of the algorithm is warranted to improve the accuracy of the device. Future study is also needed to assess the efficacy of the device in promoting self-management and asthma outcomes.

Baseline management of asthma control

Asthma is a complex, chronic inflammatory disease of the lower airways affecting people of all ages. Approximately 300 million individuals are currently suffering from asthma worldwide. The prevalence of asthma is estimated to range from 3% to 38% in children and from 2% to 12% in adults. The disease causes lost school and work days, limitations in daily activities, and sleep disturbances. Lung function impairment also occurs, resulting in decreased quality of life unless disease control is achieved and a high annual financial burden is incurred. Achievement and maintenance of control through assessment of clinical manifestations and future risk has become the aim of treatment over the years. Unfortunately, the desired level of asthma control has not been achieved in a considerable number of regions throughout the world, and the level of control is overestimated by both patients and their parents. This review examines the mortality and morbidity rates for asthma, emphasizes the challenges inherent to control management, and provides data on the tools used to measure control level.

Symptoms, feelings, activities and medication use in adolescents with uncontrolled asthma: lessons learned from asthma diaries

This study was to describe symptoms, feelings, activities and medication use reported by adolescents with uncontrolled asthma on their 24-hour asthma diaries. Adolescents with uncontrolled asthma (13-17 years, N=29) completed asthma diaries and audio-recorded symptom sounds for 24 hours. A variety of symptoms were reported, and the most frequently reported symptoms were coughing followed by wheezing. Most self-reported coughing and wheezing were verified by audio-recordings. Participants reported predominantly negative feelings and low levels of activities. High discordance between self-reports and medical records in medications was noted, raising a concern of poor treatment adherence in this vulnerable group.

Determinants of quality of life in children with asthma

BACKGROUND

HRQoL in children with asthma depends on multiple factors, among which asthma severity and level of control are believed to play a vital role. The determinants of the connection between asthma severity and asthma control with quality of life remain unclear.

AIMS

Primary aim of the study was to evaluate the HRQoL in children with asthma and to determine the factors that affect it.

MATERIALS AND METHODS

In total 504 children and one of their parents were recruited during a regular follow up visit in an outpatient asthma clinic. The measures used were the DISABKIDS smiley measure (DSmM), chronic generic measure-long form (DCGM-37) and the Condition-specific modules for asthma along with a special form for collecting demographic and clinical characteristics.

RESULTS

Three hundred fifteen children with mean age 5.35 years (Group A) and 189 with mean age 10.79 years (Group B), were recruited. Children with controlled asthma had significant higher mean score than the other asthma control groups (P < 0.001). Corticosteroid use, asthma severity, number of visits in doctor's office and lack of asthma control were significantly associated with the DCGM-37 scores as well as Impact Scale and Worry Scale. Lack of Asthma Control was the only factor that was associated with negative HRQoL in all the multiple regression models, controlling for the effect of the other covariates, in both age groups.

CONCLUSIONS

In conclusion, the evaluation of asthma HRQoL independently reflects the asthma control state and a dimension of its severity. These results highlight the need to modify asthma management strategy.

Impact of antiretroviral therapy on quality of life in HIV-infected Southeast Asian children in the PREDICT study

Quality of life (QOL) is an important antiretroviral treatment (ART) outcome. We compared QOL among 299 Thai and Cambodian children ages 1-12 years-old, CD4 15-24% randomized to early (ART at week 0, N=149) versus deferred groups (ART when at CD4 <15%, N=150) and also compared with QOL data from age-matched healthy controls (N=275). Primary caregivers completed PACTG QOL questionnaires at week 0 and every 24 weeks until 144 weeks. Children were enrolled during March 2006 to September 2008. Mean (SD) age of children was 6.3 (2.8) years, 58% were female, 60% were Thai, %CDC N:A:B:C was 2:62:36:0%. During 144 weeks, all children in the early-group and 69 (46%) of deferred-group children started ART. There was no significant difference of QOL scores between treatment groups at baseline (all p>0.05) and at week 144 (all p>0.05). By multivariate analysis, the early-group had higher QOL score changes in five domains, including health perception (p=0.04), physical resilience (p=0.02), psychosocial well-being (p=0.04), social and role functioning (p<0.01), and symptoms (p=0.01) compared to the deferred group. QOL of HIV-infected children in both groups were lower than healthy control in all 7 domains at baseline (all p<0.05) and 5 of 7 domains at weeks 144 (p<0.01). In conclusion, no significant difference of QOL scores between treatment groups. Early ART commencement associated with greater increase of QOL scores over 144 weeks. QOL scores in HIV-infected children were lower than healthy controls.
