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

Remote digital health technologies for improving the care of people with respiratory disorders

Respiratory diseases are a leading cause of morbidity and mortality globally. However, existing systems of care, built around scheduled appointments, are not well designed to support the needs of people with chronic and acute respiratory conditions that can change rapidly and unexpectedly. Home-based and personal digital health technologies (DHTs) allow implementation of new models of care catering to the unique needs of individuals. The high number of respiratory triggers and unique responses to them require a personalised solution for each patient. The real-world, repetitive monitoring capabilities of DHTs enable identification of the normal operating characteristics for each individual and, therefore, recognition of the earliest deviations from that state. However, despite this potential, the number of clinical efficacy studies of DHTs is quite small. Evaluation of clinical effectiveness of DHTs in improving health quality in real-world settings is urgently needed.

Contribution of caregiver and child anxiety and depressive symptoms to child asthma-related quality of life

BACKGROUND

Depression and anxiety negatively affect asthma-related quality of life (QoL). Yet, little is known regarding mood and asthma-related factors that best uniquely explain asthma-related QoL in children.

OBJECTIVE

This cross-sectional study evaluated the unique variance explained by caregiver and child depressive and anxiety symptom severity in child asthma-related QoL, apart from that explained by demographics and asthma control.

METHODS

Children aged 7 to 17 years with asthma (n = 205) and their caregivers with major depressive disorder were included. A 3-stage hierarchical linear regression analysis was conducted with the Pediatric Asthma Quality of Life Questionnaire total scores considered as the outcome. Predictors included demographic characteristics (stage 1); asthma control assessed by the Asthma Control Test (stage 2); and caregiver depression and anxiety (Hamilton Rating Scale for Depression and the Spielberger State/Trait Anxiety Scale) and child depression and anxiety (Children's Depression Inventory and the Screen for Child Anxiety-Related Disorders) (stage 3).

RESULTS

Demographic characteristics accounted for only 5.5% of the Pediatric Asthma Quality of Life Questionnaire scores. Asthma control significantly increased variance explained in QoL to 32.6%, whereas caregiver and child depression and anxiety symptoms significantly increased variance explained to 42.6%. Child anxiety was found to uniquely explain the largest proportion of variance in QoL (rs2 = 0.584).

CONCLUSION

After adjusting variance in QoL for demographic characteristics and asthma control, caregiver and child depression and anxiety measures significantly increased the proportion of variance explained in a child's asthma-related QoL. In addition to better asthma control, child and caregiver depression and anxiety should be addressed to increase child asthma-related QoL.

Study of the emotional adjustment of the caregiver-patient dyad to bronchial asthma in adolescence

AIM

This study aimed to investigate the impact of bronchial asthma-related factors on the emotional well-being of adolescents with bronchial asthma and their primary caregivers.

BACKGROUND

Bronchial asthma is a common chronic disease in childhood and adolescence that can have a psychological impact on both patients and their primary caregivers.

METHODS

The study used a cross-sectional design and included 150 patient-caregiver dyads diagnosed with bronchial asthma, aged between 12 and 16 years and collected between 2018 and 2020. It assessed the emotional adjustment of both patients and caregivers and recorded variables related to the disease. Qualitative and quantitative analyses were conducted to perform statistical analyses.

RESULTS

Caregivers had higher anxiety and depression scores than patients. Good adherence to treatment was necessary for the emotional adjustment of the dyad. Controlled asthma, good adherence to treatment and a reduction in medical treatment were the primary predictors of emotional adjustment.

CONCLUSIONS

The study highlights the importance of assessing anxiety and depression levels in both patients and caregivers because the presence of these symptoms can lead to the misuse of medication, inadequate inhalation techniques, the omission of medication and reduced confidence in controlling asthma symptoms.

Dupilumab leads to better-controlled asthma and quality of life in children: the VOYAGE study

BACKGROUND

Dupilumab has shown long-term treatment benefits in children with uncontrolled asthma. We assessed in more detail the impact of dupilumab on asthma control and health-related quality of life (HRQoL) in children and their caregivers.

METHODS

Children aged 6-11 years with uncontrolled moderate-to-severe type 2 asthma (baseline blood eosinophils ≥150 cells·µL-1 or fractional exhaled nitric oxide ≥20 ppb; n=350) were treated with dupilumab or placebo for 52 weeks in the VOYAGE study. Primary outcomes of these analyses were asthma control (change from baseline in Asthma Control Questionnaire 7 Interviewer-Administered (ACQ-7-IA) and achieving a clinically meaningful response of ≥0.5 points); proportion of patients achieving well-controlled asthma or better (ACQ-7-IA ≤0.75 points); effect on patients' (Standardised Paediatric Asthma Quality of Life Questionnaire Interviewer-Administered (PAQLQ(S)-IA)) and caregivers' (Paediatric Asthma Caregiver's Quality of Life Questionnaire (PACQLQ)) HRQoL; and allergic rhinitis-related QoL.

RESULTS

Dupilumab versus placebo significantly improved children's ACQ-7-IA scores by week 4 with sustained improvements through week 52 (least squares mean difference at week 52: -0.44, 95% CI -0.59- -0.30; p<0.0001); a higher proportion achieved a clinically meaningful response (week 52: 86% versus 75%; p=0.0051). At weeks 24 and 52, more children who received dupilumab achieved well-controlled asthma (ACQ-7-IA ≤0.75 points: 61% versus 43%; p=0.0001 and 70% versus 46%; p<0.0001, respectively). Significant improvements in PAQLQ(S)-IA and PACQLQ scores were observed by week 52.

CONCLUSIONS

In children aged 6-11 years with moderate-to-severe type 2 asthma, dupilumab treatment was associated with rapid, sustained improvements in asthma control. HRQoL was significantly improved for children and their caregivers.

Youth and caregiver asthma functioning and quality of life throughout the COVID-19 pandemic

Objectives

The COVID-19 pandemic resulted in daily functioning changes for many families. Adjustments in daily functioning may have impacted asthma management and subsequent morbidity. The current study seeks to build upon extant literature by exploring differences in youth asthma exacerbations and control, as well as youth and caregiver asthma-related quality of life (ArQOL) throughout COVID-19 transitional points.

Methods

Ninety-three youth (9-17 years old) with asthma and their caregivers completed measures of demographic/medical information, asthma control, and ArQOL. Participants were recruited between January 2020 and October 2021 via their medical appointments and a hospital registry. We conducted Kruskal-Wallis H-tests to examine differences in youth asthma exacerbations (measured by short-acting beta agonist use), asthma control, and ArQOL, as well as caregiver ArQOL, across phases of the COVID-19 pandemic.

Results

Asthma exacerbations were higher prior to the onset of the pandemic compared to "during lockdown" and "post-lockdown," H(2) = 7.31, p < .05. Youth's asthma control was lower prior to the onset of the pandemic compared to youth enrolled "post-lockdown," H(2) = 7.04, p < .05. There were no differences in youth ArQOL across the duration of the pandemic. Caregiver ArQOL was significantly higher in the "post-lockdown," period, compared to caregivers enrolled prior to the pandemic onset, H(2) = 9.86, p < .01.

Conclusion

Youth and caregiver asthma functioning improved following the onset of the pandemic. These findings build upon existing literature to highlight higher ArQOL in caregivers following the pandemic onset, likely related to improvements in youth asthma control and morbidity. Future research should explore trajectories of asthma and psychosocial functioning throughout the pandemic for families.

The Role of Eosinophil-Derived Neurotoxin and Vascular Endothelial Growth Factor in the Pathogenesis of Eosinophilic Asthma

Asthma is a chronic complex pulmonary disease characterized by airway inflammation, remodeling, and hyperresponsiveness. Vascular endothelial growth factor (VEGF) and eosinophil-derived neurotoxin (EDN) are two significant mediators involved in the pathophysiology of asthma. In asthma, VEGF and EDN levels are elevated and correlate with disease severity and airway hyperresponsiveness. Diversity in VEGF polymorphisms results in the variability of responses to glucocorticosteroids and leukotriene antagonist treatment. Targeting VEGF and eosinophils is a promising therapeutic approach for asthma. We identified lichochalcone A, bevacizumab, azithromycin (AZT), vitamin D, diosmetin, epigallocatechin gallate, IGFBP-3, Neovastat (AE-941), endostatin, PEDF, and melatonin as putative add-on drugs in asthma with anti-VEGF properties. Further studies and clinical trials are needed to evaluate the efficacy of those drugs. AZT reduces the exacerbation rate and may be considered in adults with persistent symptomatic asthma. However, the long-term effects of AZT on community microbial resistance require further investigation. Vitamin D supplementation may enhance corticosteroid responsiveness. Herein, anti-eosinophil drugs are reviewed. Among them are, e.g., anti-IL-5 (mepolizumab, reslizumab, and benralizumab), anti-IL-13 (lebrikizumab and tralokinumab), anti-IL-4 and anti-IL-13 (dupilumab), and anti-IgE (omalizumab) drugs. EDN over peripheral blood eosinophil count is recommended to monitor the asthma control status and to assess the efficacy of anti-IL-5 therapy in asthma.

Quality of life in patients with asthma: Medical indicators and psychological variables

BACKGROUND

Quality of life (QoL) is a widely studied term concerning asthma because it allows the impact of the disease on the patient's life to be assessed through the patient's perception. The study aims to analyze which asthma-related, psychological, and family variables affect the QoL of adolescents with asthma.

DESIGN AND METHODS

This cross-sectional design involves 150 patients diagnosed with asthma aged between 12 and 16 years. The patients' emotional symptomatology, the threat of illness, self-esteem, bonds, quality of life, family, and disease variables were assessed. Statistical analyses were performed using QCA models.

RESULTS

The results indicate that girls have a poorer QoL, and age is negatively associated. QCA models found that the variables that best explained the quality of life of these patients, in the case of the medical indicators, were control, good compliance, shorter diagnosis times, and improvement. Regarding psychological variables: a lower threat of illness, less emotional distress, and better parental mood explained the high QoL.

CONCLUSIONS AND PRACTICAL IMPLICATIONS

Adolescent QoL is affected by variables related to their asthma that are beyond their control and other psychological and family variables that may increase the perception of their QoL.

Perceived Stress in the Primary Caregivers of Adolescents with Asthma: A Cross-Sectional Study

This study aims to determine the impact of the disease on the perceived stress levels of caregivers of adolescents with asthma. A total of 140 primary caregivers, whose mean age was 45.43 years (SD = 5.03), of whom 85% were mothers, were assessed using the perceived stress questionnaire (PIP), and medical indicators related to asthma were recorded. Mean comparisons, correlations, and qualitative comparative analysis (QCA) models were used. The results indicated moderate levels of perceived stress in caregivers, no kinship differences were found, and age was negatively associated with perceived stress. QCA models suggested that perceived stress could be explained by a higher frequency of visits, poorer adherence, more frequent daily medication doses, and higher severity of asthma. In conclusion, the development of psychological interventions addressing the subjective overload of the family caregiver may benefit them, increasing their well-being, and in turn help to manage the emotional difficulties of adolescents.

Dupilumab efficacy and safety in patients with moderate to severe asthma: A systematic review and meta-analysis

Background: Dupilumab is a human monoclonal antibody directed against the alpha subunit of the interleukin-4 receptor and inhibits the signaling of IL-4 and IL-13. It is approved for treating asthma and other type-2 inflammatory diseases. There is a conflict in the literature regarding the safety and efficacy of dupilumab. Thus, we aimed to assess the safety and efficacy of dupilumab in patients with moderate to severe asthma.

Methods: Six databases (PubMed, Embase, Scopus, Web of Science, Cochrane library, and clinicaltrials.gov registry) were searched until January 2022. We included randomized controlled trials that compared dupilumab with the placebo in moderate to severe asthma patients. We extracted the data at 12 and 24 weeks and analyzed them using review manager 5.4.

Findings: Thirteen trials were included. Dupilumab significantly improved the forced expiratory volume in 1 s, asthma control questionnaire score, the fraction of exhaled nitric oxide level, and immunoglobulin E level at 12 and 24 weeks (p < 0.05). However, it was associated with increased blood eosinophils at 12 and 24 weeks. Dupilumab was generally a safe agent for asthmatic patients. It showed no significant difference compared with the placebo regarding most adverse events.

Conclusion: Dupilumab improves pulmonary function and reduces local and systemic inflammatory markers with minimal adverse events in patients with moderate to severe asthma.

Harshness and unpredictability: Childhood environmental links with immune and asthma outcomes

The environment has pervasive impacts on human development, and two key environmental conditions - harshness and unpredictability - are proposed to be instrumental in tuning development. This study examined (1) how harsh and unpredictable environments related to immune and clinical outcomes in the context of childhood asthma, and (2) whether there were independent associations of harshness and unpredictability with these outcomes. Participants were 290 youth physician-diagnosed with asthma. Harshness was assessed with youth-reported exposure to violence and neighborhood-level murder rate. Unpredictability was assessed with parent reports of family structural changes. Youth also completed measures of asthma control as well as asthma quality of life and provided blood samples to assess immune profiles, including in vitro cytokine responses to challenge and sensitivity to inhibitory signals from glucocorticoids. Results indicated that harshness was associated with more pronounced pro-inflammatory cytokine production following challenge and less sensitivity to the inhibitory properties of glucocorticoids. Furthermore, youth exposed to harsher environments reported less asthma control and poorer quality of life. All associations with harshness persisted when controlling for unpredictability. No associations between unpredictability and outcomes were found. These findings suggest that relative to unpredictability, harshness may be a more consistent correlate of asthma-relevant immune and clinical outcomes.

Expression of LINC00847 in Peripheral Blood Mononuclear Cells of Children with Asthma and Its Prediction between Asthma Exacerbation and Remission

Objective. Asthma is defined as a heterogeneous disease that is usually characterized by chronic airway inflammation. Long noncoding RNAs play important roles in various biological processes including inflammation. To know more about the relationships between lncRNAs and asthma, we sought to the role of LINC00847 in peripheral blood mononuclear cells (PBMCs) of children with asthma exacerbation or asthma remission. Methods. Microarray analysis was performed on GSE143192 and GSE165934 datasets to screen differentially expressed lncRNAs (DElncRNAs) in human PBMCs between asthma patients and normal controls. LINC00847 was selected from DElncRNAs in human PBMCs between asthma patients and normal controls for further investigation. The expression levels of LINC00847 were quantified in PBMCs collected from 54 children with asthma exacerbation, 54 children with asthma remission, and 54 healthy children by real-time qPCR. The forced expiratory volume in the first second in percent predicted values (FEV1%), ratio of forced expiratory volume in 1 second to forced vital capacity (FEV1/FVC), and peak expiratory flow rate (PEF%) were tested for evaluation of lung function. The concentration of immunoglobulin E (IgE) and eosinophil count was examined. The serum levels of interleukin-4 (IL-4), interferon-γ (IFN-γ), and IL-17A were determined by the ELISA method. Results. The expression level of LINC00847 in PBMCs of asthma exacerbation children was remarkably higher than that in PBMCs of asthma remission children and healthy children ( $p<0.001$ ); the expression level of LINC00847 in PBMCs of asthma remission children was notably higher than that in PBMCs of healthy children ( $p<0.001$ ). Pearson correlation analysis revealed that the expression levels of LINC00847 in PBMCs of asthma children were negatively correlated with FEV1% (r = −0.489), FEV1/FVC (r = −0.436), PEF% (r = −0.626), and IFN-γ level (r = −0.614) of asthma children, but positively correlated with IgE concentration (r = 0.680), eosinophil count (r = 0.780), IL-4 (r = 0.524), and IL-17A (r = 0.622) levels. When LINC00847 expression was used to distinguish asthma exacerbation from asthma remission, a 0.871 AUC (95% CI: 0.805–0.936) was yielded with sensitivity of 79.63% and specificity of 77.78%. Conclusion. The study demonstrates that increased LINC00847 expression may be associated with the development and progression of asthma, possibly serving as a novel biomarker for predicting asthma exacerbation from asthma remission.

Doxofylline for Pediatric Asthma Steps 1-4. Pediatric Asthma: New Role for an Old Drug

The panoply of anti-asthma drugs for children between 6 and 18 years is not limited to those reported in the guidelines. In this review, we will re-assess the role of doxofylline, a xanthine characterized by a much higher handling than that of theophylline, as add-on treatment in pediatric asthma grade 1-4. Ten studies evaluated doxofylline in the treatment of asthma of patients non-responsive to the first-line inhaled corticosteroids. Of these, two included children and one was exclusively pediatric. According to their results, doxofylline exerts a powerful bronchodilator and anti-inflammatory activity, which can be exploited when the inhaled oral corticosteroids are not sufficient to get the desired effect of reducing symptoms. Unlike theophylline, doxofylline does not require blood testing. It can be administered together with or as an alternative to a series of other drugs considered in additional therapy.

Dupilumab in Children with Uncontrolled Moderate-to-Severe Asthma

BACKGROUND

Children with moderate-to-severe asthma continue to have disease complications despite the receipt of standard-of-care therapy. The monoclonal antibody dupilumab has been approved for the treatment of adults and adolescents with asthma as well as with other type 2 inflammatory diseases.

METHODS

In this 52-week phase 3, randomized, double-blind, placebo-controlled trial, we assigned 408 children between the ages of 6 and 11 years who had uncontrolled moderate-to-severe asthma to receive a subcutaneous injection of dupilumab (at a dose of 100 mg for those weighing ≤30 kg and 200 mg for those weighing >30 kg) or matched placebo every 2 weeks. All the children continued to receive a stable dose of standard background therapy. The primary end point was the annualized rate of severe asthma exacerbations. Secondary end points included the change from baseline in the percentage of predicted prebronchodilator forced expiratory volume in 1 second (ppFEV₁) at week 12 and in the score on the Asthma Control Questionnaire 7 Interviewer-Administered (ACQ-7-IA) at week 24. End points were evaluated in the two primary efficacy populations who had either a type 2 inflammatory asthma phenotype (≥150 blood eosinophils per cubic millimeter or a fraction of exhaled nitric oxide of ≥20 ppb at baseline) or a blood eosinophil count of at least 300 cells per cubic millimeter at baseline.

RESULTS

In patients with the type 2 inflammatory phenotype, the annualized rate of severe asthma exacerbations was 0.31 (95% confidence interval [CI], 0.22 to 0.42) with dupilumab and 0.75 (95% CI, 0.54 to 1.03) with placebo (relative risk reduction in the dupilumab group, 59.3%; 95% CI, 39.5 to 72.6; P<0.001). The mean (±SE) change from baseline in the ppFEV₁ was 10.5±1.0 percentage points with dupilumab and 5.3±1.4 percentage points with placebo (mean difference, 5.2 percentage points; 95% CI, 2.1 to 8.3; P<0.001). Dupilumab also resulted in significantly better asthma control than placebo (P<0.001). Similar results were observed in the patients with an eosinophil count of at least 300 cells per cubic millimeter at baseline. The incidence of serious adverse events was similar in the two groups.

CONCLUSIONS

Among children with uncontrolled moderate-to-severe asthma, those who received add-on dupilumab had fewer asthma exacerbations and better lung function and asthma control than those who received placebo.

Child and caregiver experiences and perceptions of asthma self-management

Asthma is the most common chronic condition of childhood. Self-management is integral to good asthma control. This qualitative paper explores how children with asthma and their parents perceive asthma, their experience with asthma, and how they manage symptoms, preventions and medications within and outside the home. We undertook 15 focus groups with 41 school-aged (6-11 years) children with asthma and 38 parents. Parents and their children attended the same focus groups. We used thematic analysis to analyse the transcripts. Our findings show the impact asthma can have on children's social and emotional wellbeing and highlight how reliant school-aged children are on their parents to effectively manage their asthma. Parents reported being unsure when their child's symptoms warranted visiting their doctor or hospital. Schools were identified as a source of difficulty regarding asthma management; families reported that children may be self-conscious about their asthma and using their inhaler at school. School policies and teachers' lack of asthma knowledge were reported to exacerbate children's reluctance to use their inhaler at school. Our results have implications for the design and implementation of children's self-management interventions for their asthma, particularly when they are at school and away from their parents.

Role of NEAT1/MiR-9-5p/SLC26A2 Pathway on Human Airway Smooth Muscle Cell

PURPOSE

Asthma is a serious inflammatory disease of the respiratory system in which airway smooth muscle cells (ASMCs) play a key role. This study aimed to investigate the expression of SLC26A2 in human ASMCs (HASMCs) and the regulatory mechanism of SLC26A2 in the proliferation and inflammatory factor production of HASMCs.

MATERIALS AND METHODS

We obtained the asthma-associated differential mRNA SLC26A2 by bioinformatics analysis in childhood acute asthma samples. To investigate its role in airway inflammation and airway remodeling, we treated HASMCs with platelet-derived growth factor (PDGF) in an in vitro model and determined SLC26A2 expression in cells using western blotting. Cell proliferation was detected by MTT and EdU assays, and cell contractile phenotype marker proteins were measured. Cell migration and production of inflammatory factors were determined by Transwell and ELISA assays. Additionally, the upstream regulatory miRNA and LncRNA of SLC26A2 were identified by bioinformatics, luciferase reporter gene, and RIP analyses.

RESULTS

SLC26A2 was significantly upregulated in bioinformatics analysis of pediatric asthma-related sample. PDGF treatment up-regulated SLC26A2 expression in HASMCs, whereas the knockdown of SLC26A2 inhibited PDGF-stimulated proliferation, migration, and production of inflammatory factors, and enhanced the expression of cell contractile phenotype marker proteins in HASMCs. Luciferase reporter and RIP experiments validated that NEAT1 targeted miR-9-5p to regulate SLC26A2, thereby influencing the biological function of PDGF-induced HASMCs.

CONCLUSION

These findings indicate that NEAT1-mediated miR-9-5p targeting of SLC26A2 inhibits the PDGF-induced proliferation and production of inflammatory factors in HASMCs. These findings highlight potential therapeutic targets for asthma and airway inflammation.

Sleep intervention for children with asthma and their parents (SKIP Study): a novel web-based shared management pilot study

STUDY OBJECTIVES

The objective of this study was to describe the feasibility, acceptability, and preliminary efficacy of a novel Sleep Intervention for Kids and Parents (SKIP). Parent and child primary sleep outcomes were total sleep time, wake after sleep onset (WASO), sleep efficiency (SE), and bedtime range.

METHODS

Children 6-11 years of age with asthma and 1 parent, both with behavioral sleep disturbance, enrolled in this single-group pilot. The 8-week shared management intervention included weekly online educational modules, goal setting, and progress reporting. Feasibility was measured by the number of dyads who were eligible, enrolled, and retained. Acceptability was measured by survey and semistructured interview. Total sleep time, WASO, SE, and bedtime range were measured by actigraphy at baseline, after the intervention, and 12-week follow-up. Mixed-effects regression models were used to determine change in sleep outcomes from baseline.

RESULTS

Thirty-three of 39 eligible dyads enrolled; of 29 dyads that started the intervention, 25 (86%) completed all study visits. SKIP was acceptable for 61% of children and 92% of parents. Compared with baseline, at follow-up, children had significantly improved WASO (-37 minutes; 95% confidence interval [CI], -44.5 to -29.7; P < .001), SE (5.4%; 95% CI, 4.2-6.5; P < .001), and bedtime range (-35.2 minutes; 95% CI, -42.9 to -27.5; P < .001). Parents also had significantly improved WASO (-13.9 minutes; 95% CI, -19.5 to -8.2; P < .001), SE (2.7%; 95% CI, 1.7-.7; P < .001), and bedtime range (-35.3 minutes; 95% CI, -51.0 to -19.7; P < .001).

CONCLUSIONS

SKIP was feasible, acceptable, and we observed improved child and parent sleep outcomes except total sleep time. Following refinements, further testing of SKIP in a controlled clinical trial is warranted.

The Effects of Caregiver Social Support and Depressive Symptoms on Child Medication Adherence and Asthma Control

The purpose of this study was to examine relationships among caregiver social support, caregiver depressive symptoms, medication adherence, and asthma control in a sample of low-income, urban, Black children aged 3–12 years with uncontrolled asthma and their caregivers. Using longitudinal data from a randomized controlled trial (RCT) assessing the efficacy of an environmental control educational intervention, we used generalized estimating equations and ordered logistic regression models to evaluate the relationship between caregiver social support (Medical Outcomes Study Social Support Survey), depressive symptoms (Center for Epidemiologic Studies Depression scale), and two child asthma outcomes: (a) medication adherence (Asthma Medication Ratio) and (b) asthma control. At baseline, 45.7% of the 208 children had very poorly controlled asthma. Nearly a third of caregivers (97% female) had clinically significant depressive symptoms at each data collection point. Social support was not associated with either asthma outcome nor did it moderate the relationship between depressive symptoms and child asthma outcomes. Higher caregiver depressive symptoms predicted decreased medication adherence (b=−0.003, SE 0.002). Moderate asthma at baseline (OR: 0.305, SE: 0.251), severe asthma at baseline (OR: 0.142, SE: 0.299), household income < $20,000 per year (OR: 0.505, SE: 0.333), and fall season (OR: 0.643, SE: 0.215) were associated with poorer asthma control. Attending to the social context of low-income, urban, Black children with asthma is critical to reduce asthma morbidity. Maternal depressive symptoms are modifiable and should be targeted in interventions to improve child asthma outcomes in this vulnerable population. The RCT was registered with ClinicalTrials.gov (NCT01981564) in October 2013.

Parent Experiences With Electronic Medication Monitoring in Pediatric Asthma Management: Qualitative Study

BACKGROUND

Electronic medication monitoring (EMM) is a digital tool that can be used for tracking daily medication use. Previous studies of EMM in asthma management have been conducted in adults or have examined pediatric interventions that use EMM for less than 1 year. To understand how to improve EMM-enhanced interventions, it is necessary to explore the experiences of parents of children with asthma, recruited from outpatient practices, who completed a 12-month intervention trial.

OBJECTIVE

The objective of our study was to use qualitative inquiry to answer the following questions: (1) how did using an EMM-enhanced intervention change parents'/caregivers' experiences of managing their child's asthma, and (2) what do parents recommend for improving the intervention in the future?

METHODS

Parents were recruited from the intervention arm of a multicomponent health intervention enhanced by Bluetooth-enabled sensors placed on inhaler medications. Semistructured interviews were conducted with 20 parents of children aged 4-12 years with asthma. Interviews were audio-recorded, transcribed, and inductively analyzed using a constant comparative approach.

RESULTS

Interview participants reflected an even mix of publicly and privately insured children and a diverse racial-ethnic demographic. Parents discussed 6 key themes related to their experience with the EMM-enhanced intervention for the management of their child's asthma: (1) compatibility with the family's lifestyle, (2) impact on asthma management, (3) impact on the child's health, (4) emotional impact of the intervention, (5) child's engagement in asthma management with the intervention, and (6) recommendations for future intervention design. Overall, parents reported that the 12-month EMM intervention was compatible with their daily lives, positively influenced their preventive and acute asthma management, and promoted their child's engagement in their own asthma management. While parents found the intervention acceptable and generally favorable, some parents identified compatibility issues for families with multiple caregivers and frustration when the technology malfunctioned.

CONCLUSIONS

Parents generally viewed the intervention as a positive influence on the management of their child's asthma. However, our study also highlighted technology challenges related to having multiple caregivers, which will need to be addressed in future iterations for families. Attention must be paid to the needs of parents from low socioeconomic households, who may have more limited access to reliable internet or depend on other relatives for childcare. Understanding these family factors will help refine how a digital tool can be adopted into daily disease management of pediatric asthma.

Investigating the relationship between social support and self-compassion by improving the adequacy of prenatal care

INTRODUCTION

Getting pregnant care is different due to the psychological problems of pregnant mothers. Self-compassion and social support are the important components of mental health. Women with higher self-compassion and social support can take full care of their pregnancies. The aim of this study was to determine the relationship between social support and self-compassion with adequate prenatal care.

METHODS

The present study is a cross-sectional descriptive study that was performed in 2018 using the available sampling method on 500 pregnant mothers referred to Isfahan health centers. Individuals entered the study if they had entry criteria and no exit criteria, and completed social support, self-compassion, and adequacy of pregnancy care questionnaires. The data were coded and analyzed by SPSS software version 22 and Pearson's correlation statistical test.

RESULTS

The results of data analysis with Pearson's correlation test showed a positive and statistically significant relationship with pregnancy care between the overall score of social support (P < 0.001) and the dimensions of social support such as family support (P < 0.002), support of friends (P < 0.004), and the support of other people (P < 0.001). The results also showed a positive and statistically significant relationship between self-compassion and prenatal care (P < 0.001). There was a significant positive relationship between the subscales of the self-empathy questionnaire, including kindness to oneself, human commonalities, mindfulness and increasing replication, and pregnancy care, but there was a significant negative relationship between subscales of isolation and self-judgment with pregnancy care.

CONCLUSION

According to the results of the present study, social support and self-compassion as two components of mental health can affect the quality of services during pregnancy. For this reason, it is recommended that health-care providers pay attention to these two issues in order to increase the level of care during pregnancy and thus ensure maternal health during pregnancy and childbirth and the health of the fetus and baby.

Allergic diseases do not impair the cognitive development of children but do damage the mental health of their caregivers

This study aimed to investigate whether children with atopic diseases exhibited different neurodevelopment function from healthy controls and whether their caregivers had differential parental stress. In total, we recruited 109 patients with atopic diseases (mean age 6.8 years, 54.1% male) and 82 healthy children (mean age 6.3 years, 54.9% male). Based on the children’s age, they underwent developmental, cognitive evaluations and attention deficit/hyperactivity disorder (ADHD) symptoms. The parenting stress of children’s caregivers was evaluated using the Chinese Health Questionnaire (CHQ-12) and Family APGAR. Of the children with atopic diseases, 87.2%, 74.3%, 29.4%, and 8.3% of them had allergic rhinitis, asthma, atopic dermatitis, and urticaria, respectively. None of these conditions were associated with children’s cognitive profiles or ADHD symptoms. However, the caregivers of patients who had asthma suffered from higher CHQ-12 scores than those of patients without asthma. Furthermore, the number of atopic diseases had a dose–response effect on caregivers’ CHQ-12 scores. In conclusion, allergic diseases did not impair the cognitive development of children. However, caregivers of patients with asthma or multiple atopic diseases may suffer a greater mental health burden with regard to caring for their children. Such caregivers may require support to effectively fulfill their parenting roles.

Psychological and Socioeconomic Burdens Faced by Family Caregivers of Children With Asthma: An Integrative Review

INTRODUCTION

Asthma affects nearly 1 in every 12 children in the United States. Caring for a child with asthma poses significant challenges for the parent or caregiver. The purpose of this integrative review was to identify the psychological and socioeconomic burdens faced by family caregivers of children with asthma.

METHOD

An integrative review was conducted to review and appraise 80 studies.

RESULTS

Psychosocial burdens included decreased mental health, quality of life, sleep, family stress, educational deficits, cultural and health disparities, and health care communication challenges. Socioeconomic burdens included poor access to care, as well as work and financial challenges. Studies demonstrated a link between family caregiver health and child health outcomes. Facilitators included education and empowerment, social support, and use of technology.

DISCUSSION

As the family caregiver's health directly affects the asthmatic child's health, addressing the burdens of family caregivers should be a key consideration in pediatric asthma care.

Effects of maintaining web-based diaries by caregivers on adherence to care regimens in preschoolers with asthma

BACKGROUND

The objective of this pilot study was to assess the effects of maintaining web-based diaries by the caregivers of preschoolers with asthma on the adherence to asthma care regimens, the recognition of asthma symptoms, and their perceived levels of parenting stress, quality of life, and family functioning.

DESIGN AND METHODS

The caregivers of preschoolers with asthma completed a 4-week web-based diary and received weekly emails that depicted their children's asthma symptoms. We compared asthma symptoms from before and after the intervention. We analyzed demographic data, such as the caregivers' age and education, and assessment scores from the Japanese Pediatric Asthma Control program (JPAC), Adherence with Asthma Management for Caregivers of Preschoolers (AAMCP), General Functioning subscale of the Family Assessment Device (GF-FAD), Parenting Stress Index Short Form (PSI-SF), and Quality of Life assessment scale for Caregivers of Asthmatic Children 24 (QOLCA-24).

RESULTS

A total of 45 participants were included in the analyses. The mean scores depicting asthma control were significantly improved postintervention (pre: 12.29 ± 2.65; post: 13.02 ± 2.01; t = -2.15, p = .037). Mean AAMCP scores postintervention (52.13 ± 6.25) were significantly greater than before (49.78 ± 7.20; t = -3.07; p = .004).

PRACTICE IMPLICATIONS

Adherence to asthma care and the recognition of asthma symptoms improved following the use of a web-based diary, making it a potential cost-effective intervention for asthma patients and their families.

Randomized clinical trial of parental psychosocial stress management to improve asthma outcomes

OBJECTIVE

Because higher parental psychosocial stress is associated with worsened asthma outcomes in children, we sought to determine if a parent-focused stress management intervention would improve outcomes among their at-risk African American children.

METHODS

We enrolled self-identified African American parent-child dyads (children aged 4-12 years old with persistent asthma, no co-morbidities, on Medicaid) in a prospective, single-blind, randomized clinical trial with follow-up at 3, 6, and 12 months. All children received care based on the guidelines of the National Institutes of Health. Developed with extensive local stakeholder engagement, the intervention consisted of four individual sessions with a community wellness coach (delivered over 3 months) supplemented with weekly text messaging and twice monthly group sessions (both delivered for 6 months). The main outcome was asthma symptom-free days in the prior 14 days by repeated measures at 3 and 6 months follow-up.

RESULTS

We randomized 217 parent-child dyads and followed 196 (90.3%) for 12 months. Coaches completed 338/428 (79%) of all individual sessions. Symptom-free days increased significantly from baseline in both groups at 3, 6, and 12 months, but there were no significant differences between groups over the first 6 months. At 12 months, the intervention group sustained a significantly greater increase in symptom-free days from baseline [adjusted difference = 0.92 days, 95% confidence interval (0.04, 1.8)].

CONCLUSION

The intervention did not achieve its primary outcome. The efficacy of providing psychosocial stress management training to parents of at-risk African American children with persistent asthma in order to improve the children's outcomes may be limited.

Association between second hand smoke (SHS) exposure and caregiver stress in children with poorly controlled asthma

Objective: Urban children with asthma experience high rates of second hand smoke (SHS) exposure. The objective was to examine whether SHS exposure is associated with symptom frequency in children with poorly controlled asthma. Methods: Children were enrolled in a RCT to test the efficacy of an environmental control behavioral intervention versus an attention control group and followed over 12 months. SHS exposure assessed using salivary cotinine measurement. Frequency of child asthma symptoms, healthcare utilization, household smoking and caregiver daily life stress were obtained via caregiver report. Time of enrollment was recorded to assess seasonal factors. Symptom days and nights were the primary outcomes. Multivariable models and odds ratios examined factors that best predicted increased frequency of daytime/nighttime symptoms. Results: Children (n = 222) with a mean age of 6.3 (SD 2.7) years, were primarily male (65%), African American (94%), Medicaid insured (94%), and had poorly controlled asthma (54%). The final multivariable model indicated symptoms in the fall (OR 2.78; 95% CI 1.16, 6.52) and increased caregiver daily life stress (OR 1.13, 95% CI 1.02, 1.25) were significantly associated with increased symptom days when controlling for cotinine level, intervention status, child age and home and car smoking restrictions. Conclusions: There was no impact of SHS exposure on increased symptom frequency. High caregiver daily life stress and symptoms in fall season may place children with asthma at risk for increased day/nighttime symptoms. Close monitoring of symptoms and medication use during the fall season and intervening on caregiver life stress may decrease asthma morbidity in children with poorly controlled asthma.

Severe asthma in children: Evaluation and management

Severe asthma in children is associated with significant morbidity. Children with severe asthma are at increased risk for adverse outcomes including medication-related side effects, life-threatening exacerbations, and impaired quality of life. It is important to differentiate between severe therapy resistant asthma and difficult-to-treat asthma due to comorbidities. The most common problems that need to be excluded before a diagnosis of severe asthma can be made are poor medication adherence, poor medication technique or incorrect diagnosis of asthma. Difficult to treat asthma is a much more common reason for persistent symptoms and exacerbations and can be managed if comorbidities are clearly addressed. Children with persistent symptoms and exacerbations despite correct inhaler technique and good medical adherence to standard Step 4 asthma therapies according to the guidelines^1,2, should be referred to an asthma specialist with expertise in severe asthma.

Informal Support among Low-income Mothers Post Welfare Reform: A Systematic Review

The vulnerability and instability of low-income mothers situated in a context with a weak public safety net make informal social support one of few options many low-income mothers have to meet basic needs. This systematic review examines (a) social support as an empirical construct, (b) the restricted availability of one important aspect of social support-informal perceived support, hereafter informal support-among low-income mothers, (c) the role of informal support in maternal, economic, parenting, and child outcomes, (d) the aspects of informal support that influence its effects, and (e) directions for future research. Traditional systematic review methods resulted in an appraisal of 65 articles published between January 1996 and May 2017. Findings indicated that informal support is least available among mothers most in need. Informal support provides some protection from psychological distress, economic hardship, poor parenting practices, and poor child outcomes. To promote informal support and its benefits among low-income families, future research can advance knowledge by defining the quintessential characteristics of informal support, identifying instruments to capture these characteristics, and providing the circumstances in which support can be most beneficial to maternal and child well-being. Consistent measurement and increased understanding of informal support and its nuances can inform intervention design and delivery to strengthen vulnerable mothers' informal support perceptions thereby improving individual and family outcomes.

Improving Care of Inner-City Children with Poorly Controlled Asthma: What Mothers Want You to Know

INTRODUCTION

Low-income caregiver perspectives on asthma management are understudied but may illuminate strategies to improve care delivery and child outcomes.

METHOD

Purposive sampling methods were used to recruit 15 caregivers of children with frequent asthma emergency department visits. Interviews explored how poverty and stress affect asthma management. Grounded theory coding techniques were used to analyze the data.

RESULTS

Participants were the biological mother (100%) and were poor (75% had mean annual income ≤ $30,000). Their children (mean age = 6.9 years) were African American (100%), enrolled in Medicaid (100%), and averaged 1.5 emergency department visits over the prior 3 months. Four themes emerged: (a) Deplorable Housing Conditions, (b) Allies and Adversaries in School-Based Asthma Management, (c) Satisfaction With Asthma Health Care Delivery, and (d) Prevalent Psychological Distress.

DISCUSSION

Impoverished caregivers of children with frequent asthma emergency department visits describe stress that is multifaceted, overwhelming, and difficult to eradicate. Their experiences underscore the need for improved school-based asthma management and family-centered approaches to health care delivery.

Quality of Life and African American Women Who are Family Caregivers: A Literature Review with Implications for Psychiatric Mental Health Advanced Practice Registered Nurses

PURPOSE

To identify factors affecting the quality of life (QOL) of African American women (AAW) family caregivers of individuals with kidney failure.

METHODS

Ferrans' Conceptual Model of QOL provided the framework for this literature review. Included studies were (a) peer- reviewed, (b) published within the last ten years, (c) written in English, and (d) examined QOL of AAW family caregivers. Using CINAHL© and PubMed©, we found 14 studies that described factors associated with these caregivers' QOL.

SCOPE

Few studies document the QOL of AAW who are family caregivers, especially in the context of kidney failure. Psychiatric Mental Health Advanced Practice Registered Nurses need to learn about the factors influencing the QOL of these caregivers.

RESULTS

No studies were found within the last ten years that explored the QOL of AAW family caregivers of individuals with kidney failure. Findings reflected the QOL of AAW family caregivers in the context of other chronic conditions. Various factors such as stress, insomnia, and employment were linked to an impaired QOL. Implications for practice, research and education for PMH-APRNs are suggested.

CONCLUSION

PMH-APRNs are uniquely trained to address many factors that affect the QOL of these caregivers and may provide holistic care aimed at promoting satisfactory QOL for these caregivers.

Primary and Secondary Caregiver Reports of Quality of Life in Pediatric Asthma: Are They Comparable?

PURPOSE

This study aimed to compare primary and secondary caregiver QOL within families of children with asthma and determine the potential importance of including secondary caregiver QOL in clinical and research settings.

METHODS

Participants included 118 families of children with asthma that had primary and secondary caregivers. Families completed measures in a single research session. Caregivers reported on QOL, psychological functioning, and family burden; children completed a measure of QOL. Child lung function was determined from objective spirometry. Adherence to prescribed controller medication was measured for 6 weeks following the research visit.

RESULTS

Primary caregiver QOL was significantly lower than secondary caregiver QOL (Mean overall QOL of 5.85 versus 6.17, p < .05). Better medication adherence was associated with higher primary caregiver QOL (ρ = .22, p = .02); secondary caregiver QOL, not primary caregiver QOL, was positively associated with child QOL (ρ = .20, p = .03). Families with discrepant QOL scores between caregivers (difference in scores of at least .50) were characterized by more family burden and primary caregiver psychological symptoms.

CONCLUSIONS

Differences in QOL scores between caregivers may be a reflection of primary caregivers' greater investment in daily asthma management. In families reporting low burden and few psychological difficulties in the primary caregiver, QOL assessments from either caregiver may may be informative and representative of how parents are adapting to child asthma. In families experiencing high levels of burden or more primary caregiver psychological difficulties, QOL reports from secondary caregivers may not be as clinically meaningful.

Family Health-related Quality of Life in Pediatric Cyclic Vomiting Syndrome

OBJECTIVE

The aim of the study was to evaluate the relationship of disease characteristics and child anxiety symptoms to family health-related quality of life (FHRQoL) in youth with cyclic vomiting syndrome (CVS).

METHODS

Forty-two parents of youth ages 8 to 18 years diagnosed with CVS completed the Family Impact Module of the PedsQL, a measure of the impact of the child's illness on the family. We evaluated the relationship of disease characteristics and child and parent proxy reports of anxiety symptoms on the Screen for Childhood Anxiety and Related Emotional Disorders to FHRQoL.

RESULTS

Parent report of child anxiety symptoms and missed school days (mean = 11.93, standard deviation = 14.62) were the strongest predictors of FHRQoL (r = 0.33, df = 1.39, F = 8.51, P = 0.006). Other disease characteristics, including frequency, duration, chronicity of CVS episodes, and delay in initial CVS diagnosis were not significantly associated with the FHRQoL total score. Child anxiety symptoms by either parent and/or child report were associated with subscales of the FHRQoL, including family physical functioning, family communication, and family daily activities.

CONCLUSIONS

HRQoL for the families assessed in this study was associated with anxiety symptoms to a greater extent than disease characteristics, indexing the importance of a biopsychosocial approach to CVS management. Screening for anxiety symptoms and support for school absences due to illness are indicated to help lessen the impact of CVS on the family as a whole.

Very Poorly Controlled Asthma in Urban Minority Children: Lessons Learned

BACKGROUND

Very poorly controlled (VPC) asthma in children is associated with ongoing acute exacerbations but factors associated with VPC are understudied.

OBJECTIVE

To examine the risk factors associated with VPC asthma in urban minority children.

METHODS

This descriptive study examined asthma control levels (well-controlled [WC], not well-controlled [NWC], and VPC) at baseline and 6 months in children participating in an ongoing randomized controlled trial of an emergency department/home environmental control intervention. Data collection occurred during the index emergency department visit and included allergen-specific IgE and salivary cotinine testing and caregiver interview of sociodemographic and child health characteristics. Follow-up data were collected at 6 months. Unadjusted analyses examined the association of sociodemographic and health characteristics by level of asthma control. Multivariate analysis tested significant factors associated with VPC asthma at 6 months.

RESULTS

At baseline most children were categorized with VPC asthma (WC, 0%; NWC, 47%; VPC, 53%) and rates of VPC minimally improved at 6 months (WC, 13%; NWC, 41%; VPC, 46%). Risk for VPC asthma was twice as likely in children with allergic rhinitis (odds ratio [OR], 2.42), having 2 or more primary care provider asthma visits within the past 3 months (OR, 2.77), or caregiver worry about medication side effects (OR, 2.13) and 3 to 4 times more likely when asthma control was assessed during the fall or spring season (OR: fall, 3.32; spring, 4.14).

CONCLUSIONS

Improving asthma control in low-income, high-risk children with VPC asthma requires treatment of comorbidities, attention to caregiver medication beliefs, and adept use of stepwise therapy.

The pediatric asthma yardstick: Practical recommendations for a sustained step-up in asthma therapy for children with inadequately controlled asthma

Current asthma guidelines recommend a control-based approach to management involving assessment of impairment and risk followed by implementation of treatment strategies individualized according to the patient's needs and preferences. However, for children with asthma, achieving control can be elusive. Although tools are available to help children (and families) track and manage day-to-day symptoms, when and how to implement a longer-term step-up in care is less clear. Furthermore, treatment is challenged by the 3 age groups of childhood-adolescence (12-18 years old), school age (6-11 years old), and young children (≤5 years old)-and what works for 1 age group might not be the best approach for another. The Pediatric Asthma Yardstick provides an in-depth assessment of when and how to step-up therapy for the child with not well or poorly controlled asthma. Development of this tool follows others in the Yardstick series, presenting patient profiles and step-up strategies based on current guidance documents, but modified according to newer data and the authors' combined clinical experience. The objective is to provide clinicians who treat children with asthma practical and clinically relevant recommendations for each step-up and each intervention, with the intent of helping practitioners better treat their pediatric patients with asthma, particularly those who do not always respond to recommended therapies.

Severe Asthma in Children

Severe asthma in children is associated with significant morbidity and is a highly heterogeneous disorder with multiple clinical phenotypes. Cluster analyses have been performed in several groups to explain some of the heterogeneity of pediatric severe asthma, which is reviewed in this article. The evaluation of a child with severe asthma includes a detailed diagnostic assessment and excluding other possible diagnoses and addressing poor control due to comorbidities, lack of adherence to asthma controller medications, poor technique, and other psychological and environmental factors. Children with severe asthma require significant resources including regular follow-up appointments with asthma education, written asthma action plan, and care by a multidisciplinary team. Management of pediatric severe asthma now includes emerging phenotypic-directed therapies; however, continued research is still needed to further study the long-term outcomes of pediatric severe asthma and its treatment.

The Chronicity of Depressive Symptoms in Mothers of Children With Asthma

Depression can disproportionately affect low-income women. The purpose of this study was to explore the chronicity of depressive symptoms in a sample of 276 low-income inner-city mothers of children with high-risk asthma. The aims were to identify factors (asthma health status, stress, social support) associated with change in depressive symptomatology over 12 months as well as to ascertain what factors are most consistently associated with depressive symptoms. Using latent growth curve analysis, demographic variables, asthma severity, stress, and social support failed to explain changes in depressive symptomatology. The growth curve models, however, were predictive of Center for Epidemiologic Studies-Depression Scale (CES-D) scores at distinct time points indicating that higher daily stress and lower social support were associated with increased depressive symptoms. Our data highlight the chronic nature of depressive symptoms in low-income mothers of children with poorly controlled asthma. Integrating questions about caregiver psychological state across all clinical encounters with the family may be indicated.

Caregiver perception of asthma management of children in the context of poverty

OBJECTIVE

Low-income caregivers of young children with high-risk asthma experience social stressors and illness-related demands that may impede effective home asthma management. Knowledge of the caregiving experience in the context of poverty is limited.

METHODS

Convenience sampling methods were used to recruit low-income caregivers of children aged 7-12 years, who are frequently in the Emergency Room (ED) for uncontrolled asthma. Thirteen caregivers participated in focus groups that were designed to elicit reflections on asthma home and community management from the caregiver perspective. A grounded theory approach was used in the open coding of transcript data from three focus groups, as well as to revise and reorganize emerging themes and sub-themes.

RESULTS

Participants (Mean age = 33.9 years) were predominantly the biological mother (92.3%), single (84.6%), and impoverished (69.2% reported annual household income ≤ $30,000). Their children (Mean age = 7.8 years) were African-American (100%), enrolled in Medicaid (92.3%), averaged 1.38 (SD = 0.7) ED visits over the prior 3 months, resided in homes with at least one smoker (61.5%), and nearly all (84.6%) experienced activity limitations due to asthma. Five themes emerged in the analysis: intensive caregiving role, complex and shared asthma management responsibility, parental beliefs and structural barriers to guideline-based care, lack of control over environmental triggers, and parent advocacy to improve child asthma care and outcomes.

CONCLUSIONS

Caregivers managing a child with high-risk asthma in the context of poverty indicate the need for ongoing asthma education, increased sensitivity to the complexity of home asthma management, and family-centered interventions that enhance communication and collaboration between caregivers and providers.

Inner-city asthma: special considerations for management

PURPOSE OF REVIEW

Asthma is prevalent in inner-city populations, exhibiting significant morbidity and mortality. This review focuses on the consequential findings of recent literature, providing insight into onset of asthma, complicating factors, prediction of exacerbations, and novel treatment strategies.

RECENT FINDINGS

Analyses of environmental influence on inner-city children demonstrated novel interactions, implicating potentially protective benefits from early life exposures to pests and pets and isolating detrimental effects of air pollution on asthma morbidity. Through detailed characterization of inner-city asthmatics, predictors of seasonal exacerbations surfaced. Focused, season-specific treatment of inner-city asthmatics with omalizumab identified those most likely to benefit from season-tailored therapy. Comparative studies of urban and rural populations revealed that race and household income, rather than location of residence, impose the greatest risk for increased asthma prevalence and morbidity.

SUMMARY

Challenging previously conceived exposure-disease relationships, recent literature has elucidated new avenues in the complex interplay between immunologically active exposures and their effects on inner-city asthma. These findings, and improved understanding of other relevant exposures, could steer the direction of primary (and secondary) disease prevention research. Moreover, careful identification of asthma characteristics has effectively established predictors of exacerbations, highlighting individuals for which additional therapies are warranted and for whom such treatments are most likely to be effective.
