Abstract
Head Start centers in Webb County, Texas primarily serve low-income Hispanic families disproportionately affected by environmental exposures. A total of 560 parents and employees attended environmental trainings. Pre- and post-assessments measured whether the trainings were effective at improving related knowledge and behaviors. A total of 152 parents and 94 employees signed consent forms. Only the 64 parents and 50 employees who completed all questionnaires were included in the data analysis. Paired t tests and McNemar tests found significant improvements in knowledge and behaviors related to multiple environmental topics (p < 0.05). Mean scores out of eleven for knowledge before and immediately after were 9.69 (95 % CI 9.44, 9.94) and 10.58 (95 % CI 10.42, 10.74), respectively. Mean scores out of ten for behavior before and 1 month after training were 8.00 (95 % CI 7.71, 8.29) and 9.29 (95 % CI 9.10, 9.48), respectively. This pilot study found improved knowledge and behaviors following environmental health training.

Abstract
In this paper, we review the current management of allergic rhinitis and new directions for future treatment. Currently, management includes pharmacotherapy, allergen avoidance and possibly immunotherapy. The simple washing of nasal cavities using isotonic saline provides a significant improvement and is useful, particularly in children. The most effective medication in persistent rhinitis used singly is topical corticosteroid, which decreases all symptoms, including ocular ones. Antihistamines reduce nasal itch, sneeze and rhinorrhea and can be used orally or topically. When intranasal antihistamine is used together with topical corticosteroid, the combination is more effective and acts more rapidly than either drug used alone. Alternative therapies, such as homeopathy, acupuncture and intranasal carbon dioxide, or devices such nasal air filters or intranasal cellulose, have produced some positive results in small trials but are not recommended by Allergic Rhinitis and its Impact on Asthma (ARIA). In the field of allergic immunotherapy, subcutaneous and sublingual routes are currently used, the former being perhaps more efficient and the latter safer. Sublingual tablets are now available. Their efficacy compared to standard routes needs to be evaluated. Efforts have been made to develop more effective and simpler immunotherapy by modifying allergens and developing alternative routes. Standard allergen avoidance procedures used alone do not provide positive results. A comprehensive, multi-trigger, multi-component approach is needed, including avoidance of pollutants such as cigarette smoke.

Abstract
OBJECTIVES To evaluate and compare full economic evaluation studies on the cost-effectiveness of enhanced asthma management (either as an adjunct to usual care or alone) vs. usual care alone. METHODS Online databases were searched for published journal articles in English language from year 1990 to 2012, using the search terms '"asthma" AND ("intervene" OR "manage") AND ("pharmacoeconomics" OR "economic evaluation" OR "cost effectiveness" OR "cost benefit" OR "cost utility")'. Hand search was done for local publishing. Only studies with full economic evaluation on enhanced management were included (cost consequences (CC), cost effectiveness (CE), cost benefit (CB), or cost utility (CU) analysis). Data were extracted and assessed for the quality of its economic evaluation design and evidence sources. RESULTS A total of 49 studies were included. There were 3 types of intervention for enhanced asthma management: education, environmental control, and self-management. The most cost-effective enhanced management was a mixture of education and self-management by an integrated team of healthcare and allied healthcare professionals. In general, the studies had a fair quality of economic evaluation with a mean QHES score of 73.7 (SD=9.7), and had good quality of evidence sources. CONCLUSION Despite the overall fair quality of economic evaluations but good quality of evidence sources for all data components, this review showed that the delivered enhanced asthma managements, whether as single or mixed modes, were overall effective and cost-reducing. Whilst the availability and accessibility are an equally important factor to consider, the sustainability of the cost-effective management has to be further investigated using a longer time horizon especially for chronic diseases such as asthma.

Abstract
BACKGROUND The historical series of excess winter mortality (EWM) in England and Wales presents a negative trend. Winter fuel payments (WFPs) are the most important benefits for people aged 65 or over directly related to Winter Mortality in the UK. METHODS This study presents a time series analysis of the direct effect of WFPs on EWM in England and Wales. RESULTS We find a significant structural break in trend and volatility in the EWM series in England and Wales in 1999-2000. After controlling for a number of covariates, an ARIMA-X model finds that WFPs can account for almost half of the reduction in EWM in England and Wales since 1999/2000. CONCLUSIONS Almost half of the reduction in EWM since 1999/2000 is attributable to WFPs.

Impact of asthma exacerbations and asthma triggers on asthma-related quality of life in patients with severe or difficult-to-treat asthma. THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY-IN PRACTICE 2014; 2:544-52.e1-2.

Abstract
BACKGROUND Few data are available that evaluate the relationship among asthma exacerbations, asthma triggers, and asthma-related quality of life (QoL). OBJECTIVE To evaluate the impact of asthma exacerbations and asthma triggers on QoL. METHODS Patients with severe or difficult-to-treat asthma, ages ≥ 13 years (n = 2679) from the TENOR (The Epidemiology and Natural History of Asthma: Outcomes and Treatment Regimens) 3-year observational study were included. Exacerbations were defined hierarchically in descending order of severity (hospitalization, emergency department [ED] visit, steroid burst, no exacerbation) by using data from months 6 and 12. The total number (frequency) of exacerbations was assessed. Asthma-related QoL was measured at month 12 by using the Mini-Asthma QoL Questionnaire (Mini-AQLQ); self-reported asthma triggers were collected at baseline and annually. We used 1-way ANOVA to test for differences in Mini-AQLQ domain scores across asthma exacerbation severity, the total number of asthma exacerbations, and the number of asthma triggers. RESULTS A significant decrease (P < .001) in Mini-AQLQ domain scores was seen with increasing severity of asthma exacerbation (no exacerbation, steroid burst, ED visit, and hospitalization); symptom (5.5, 4.8, 4.3, and 4.2), activity (5.8, 5.2, 4.6, and 4.4), emotional (5.6, 5.0, 4.4, and 4.2), exposure (5.0, 4.5, 4.0, and 3.9); and overall (5.5, 4.9, 4.3, and 4.1). Increasing exacerbation frequency and the number of baseline asthma triggers also were associated with significant decreases in Mini-AQLQ domain scores. An increasing number of asthma triggers were associated with an increase in severity and frequency of exacerbations. CONCLUSION Avoidance of asthma triggers may reduce exacerbation rates and improve asthma-related QoL in patients with severe or difficult-to-treat asthma. Interventional studies are warranted to further explore these outcomes.

Abstract
OBJECTIVE Asthma is the most common chronic childhood condition affecting 6.3 million (US) children aged less than 18 years. Home-based, multi-component, environmental intervention studies among children with asthma have demonstrated to be effective in reducing asthma symptoms. In this study, a local hospital and university developed an environmental intervention research pilot project, Eastern Carolina Asthma Prevention Program (ECAPP), to evaluate self-reported asthma symptoms, breathing measurements, and number of asthma-related emergency department (ED) visits among low-income, minority children with asthma living in rural, eastern North Carolina. Our goal was to develop a conceptual model and demonstrate any asthma respiratory improvements in children associated with our home-based, environmental intervention. METHODS This project used a single cohort, intervention design approach to compare self-reported asthma-related symptoms, breathing tests, and ED visits over a 6 month period between children with asthma in an intervention study group (n = 12) and children with asthma in a control study group (n = 7). The intervention study group received intense asthma education, three home visits, 2 week follow-up telephone calls, and environmental intervention products for reducing asthma triggers in the home. The control group received education at baseline and 2 week calls, but no intervention products. RESULTS At the end of the study period, significant improvements were observed in the intervention group compared with the control group. Overall, the intervention group experienced a 58% (46 ± SD 26.9) reduction in self-reported asthma symptoms; 76% (34 ± SD 29.7) decrease in rescue medicine; 12% (145 ± SD 11.3) increase in controller medicine; 37% decrease in mean exhaled nitric oxide levels and 33% fewer ED asthma-related visits. CONCLUSION As demonstrated, a combination of efforts appeared effective for improving asthma respiratory symptoms among children in the intervention group. ECAPP is a low cost pilot project that could readily be adapted and expanded into other communities throughout eastern North Carolina. Future efforts could include enhanced partnerships between environmental health professionals at local health departments and pediatric asthma programs at hospitals to carry out ECAPP.

Abstract
Community and public health interventions provide potentially powerful means of decreasing morbidity, hospitalizations, emergency room visits, and mortality from asthma. This chapter thus provides an overview of community-based interventions, which have been demonstrated to be effective-and/or ineffective-in reducing the burden of disease, including development of asthma coalitions, interventions for both provider and patient education, environmental controls to reduce exposure to asthma triggers, and institutional policy and systems change. Perhaps most important is the demonstrated effect of integrated, comprehensive approaches to asthma management and control. A multidisciplinary approach spanning T1 through T4 translational research, coupled with public health activities is promising and has already demonstrated success in reducing the burden of disease.

Abstract
We sought objectively to measure, summarize, and contextualize the asthma triggers found in the homes of urban high-risk Puerto Rican children and adolescents with asthma in Chicago. Data were from the baseline home assessments of Project CURA. Research assistants interviewed caregivers, conducted a home visual inspection, and collected saliva samples for cotinine analysis. A trigger behavior summary score was created. The housing inspected was old with multiple units and obvious structural deficiencies. Many allergic and irritant triggers were observed. Having a controller medicine or private insurance was associated with lower trigger behavior summary scores; caregiver depression, caregiver perceived stress, and child negative life events were associated with high trigger scores. The final multivariate model retained had a controller medicine, private insurance, and caregiver perceived stress. The data from this high-risk cohort identified modifiable areas where environmental interventions could reduce morbidity in Puerto Rican children and adolescents.

Abstract
Asthma prevalence rates are at an all-time high in the United States with over 25 million persons diagnosed with asthma. African Americans and other minorities have higher asthma prevalence and higher exposure to environmental factors that worsen asthma as compared to Caucasians. This article describes the evaluation of an inner-city home-based asthma education and environmental remediation program that addressed both indoor and outdoor triggers through collaboration between a health system and local environmental justice organization. The program enrolled 132 children older than 2.5 years and centers on a 4- to 6-week intervention with peer counselors using the U.S. Environmental Protection Agency Asthma Home Environment Checklist and the You Can Control Asthma curriculum. Families receive asthma-friendly environmental home kits. Peer counselors reinforce key asthma management messages and facilitate the completion of Asthma Action Plans. The environmental justice community partner organized block cleanups to reduce outdoor triggers. The evaluation used a pretest-posttest design to assess changes in client behavior and asthma symptoms. Data were collected at baseline and during a 6-month postintervention period. Participants saw enhanced conditions on asthma severity and control. The improvement was greatest for children whose asthma was considered "severe" based on the validated Asthma Control Test. Other positive results include the following: greater completion of Asthma Action Plans, significant reduction in the number of emergency room visits (p = .006), and substantial decreases in school absenteeism (p = .008) and use of rescue medications (p = .049). The evaluation suggests that the program was effective in improving asthma self-management in a high-risk population living within an environmental justice community.

Abstract
Objective Many interventions to reduce allergen levels in the home are recommended to asthma and allergy patients. One that is readily available and can be highly effective is the use of high performing filters in forced air ventilation systems. Methods We conducted a modeling analysis of the effectiveness of filter-based interventions in the home to reduce airborne asthma and allergy triggers. This work used “each pass removal efficiency” applied to health-relevant size fractions of particles to assess filter performance. We assessed effectiveness for key allergy and asthma triggers based on applicable particle sizes for cat allergen, indoor and outdoor sources of particles <2.5 µm in diameter (PM2.5), and airborne influenza and rhinovirus. Results Our analysis finds that higher performing filters can have significant impacts on indoor particle pollutant levels. Filters with removal efficiencies of >70% for cat dander particles, fine particulate matter (PM2.5) and respiratory virus can lower concentrations of those asthma triggers and allergens in indoor air of the home by >50%. Very high removal efficiency filters, such as those rated a 16 on the nationally recognized Minimum Efficiency Removal Value (MERV) rating system, tend to be only marginally more effective than MERV12 or 13 rated filters. Conclusions The results of this analysis indicate that use of a MERV12 or higher performing air filter in home ventilation systems can effectively reduce indoor levels of these common asthma and allergy triggers. These reductions in airborne allergens in turn may help reduce allergy and asthma symptoms, especially if employed in conjunction with other environmental management measures recommended for allergy and asthma patients.

Abstract
In the modern era, the prevalence of asthma and allergies are increasing. It has been speculated that environmental exposures are contributing to this rise. Several studies demonstrate that common indoor allergen exposures exacerbate asthma. Minimizing exposure to allergens and remediating the environment play a critical role in the treatment of asthma and allergies. The most effective environmental control measures are tailored multifaceted interventions which include education, thorough cleaning, using high-efficiency particulate air (HEPA) filters, integrated pest management, and maintenance of these practices.

Abstract
OBJECTIVES We evaluated health outcomes associated with in-home interventions in low-income urban households with children with asthma. METHODS A comprehensive health and environmental assessment and subsequent intervention were completed in 116 households with 170 enrolled children with asthma. Home health workers provided household safety, asthma prevention education, and targeted environmental intervention to decrease asthma triggers and improve household safety. We collected environmental data with questionnaire and dust samples and health information with a questionnaire incorporating the American Academy of Pediatrics Children's Health Survey for Asthma and other instruments at baseline and at follow-up 11 to 12 months later to evaluate the impact of the intervention on the health of the child and family in Lowell, Massachusetts, from September 2009 to January 2012. RESULTS The diverse study population of low-income children showed a statistically significant health improvement from baseline to follow-up. The cost of the interventions (not including personnel) was $36 240, whereas the estimated medical savings over a 4-week assessment period was $71 162, resulting in an estimated annual savings of about $821 304. CONCLUSIONS Low-cost, multicomponent interventions decrease all measures of asthma severity and health care utilization in a diverse population of urban children.

Abstract
The Student Asthma Research Team (START) program was designed to enable students to explore socio-ecological factors contributing to asthma through the use of Photovoice, a technique that gathers both photographs and personal experiences from participants. The photographs taken by and commentary from student participants were integrated into public service announcements (PSAs) intended to increase community asthma awareness and catalyze behavior change. This article evaluates the effectiveness of these student-directed PSAs at improving asthma awareness among peers and community members. Pre-PSA, immediate post-PSA, and 4 month post-PSA follow-up assessments were conducted to evaluate changes in community members' asthma knowledge and behavior. The student-directed PSAs were found to significantly increase asthma knowledge among community members, irrespective of age, gender, or race. Increased knowledge persisted through the 4-month post-PSA follow-up. Of the thirty-six participants who were successfully contacted for the follow-up survey, nearly 40 % reported meaningful behavior-change in response to the PSAs. Photovoice and media production techniques were effective in engaging adolescent students--an under-served and often disenfranchised population--in asthma health education through the development and dissemination of PSAs. The extension of participatory techniques such as Photovoice to include the creation of student-directed PSAs holds promise for engaging adolescents in public health initiatives within their communities.

Abstract
BACKGROUND Tobacco biomarkers including serum cotinine and urinary 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) have been used in research settings. PURPOSE The goal of the study was to examine the association of cotinine and NNAL with asthma outcomes in the U.S. adult population. METHODS A cross-sectional design was used, using data from the National Health and Nutrition Examination Survey, 2007-2008, with participants aged >20 years with self-reported asthma (N=456). Past-year asthma exacerbations and emergency room/urgent care visits for asthma were examined. Analyses were conducted in 2013. RESULTS Among adult asthmatics, 50.3% reported a past-year asthma attack (61.8% smokers, 46.6% nonsmokers, p=0.029). Among these, 24.7% reported a past-year emergency/urgent visit for asthma (34.7% smokers, 20.1% nonsmokers, p=0.034). Median concentrations of cotinine and creatinine-adjusted NNAL (NNAL/Cr) were significantly higher in those with a past-year asthma attack (0.43 ng/mL and 7.28 pg/mL) than in those without (0.06 ng/mL and 2.26 pg/mL), and highest in those with past-year emergency/urgent visits (0.93 ng/mL and 28.14 pg/mL). Among nonsmokers, increasing levels of log cotinine or log NNAL/Cr, adjusted for demographics, were significantly associated with past-year asthma exacerbation (log cotinine OR=1.46 [95% CI=1.1, 1.92]; log NNAL/Cr OR=1.42 [95% CI=1.07, 1.88]) and past-year emergency/urgent visit (log cotinine OR=1.95 [95% CI=1.32, 2.88]; log NNAL/Cr OR=1.58 [95% CI=1.23, 2.02]). Among smokers, increasing biomarker levels were not significantly associated with either outcome. CONCLUSIONS In a population-based cross-sectional analysis, increased cotinine and NNAL were found to be associated with asthma exacerbation and healthcare use in nonsmokers with asthma. If these findings are confirmed in prospective studies, these biomarkers might be candidates for clinical indicators of risk of asthma.

Abstract
OBJECTIVES We assessed the benefits of adding weatherization-plus-health interventions to an in-home, community health worker (CHW) education program on asthma control. METHODS We used a quasi-experimental design to compare study group homes (n = 34) receiving CHW education and weatherization-plus-health structural interventions with historical comparison group homes (n = 68) receiving only education. Data were collected in King County, Washington, from October 2009 to September 2010. RESULTS Over the 1-year study period, the percentage of study group children with not-well-controlled or very poorly controlled asthma decreased more than the comparison group percentage (100% to 28.8% vs 100% to 51.6%; P = .04). Study group caregiver quality-of-life improvements exceeded comparison group improvements (P = .002) by 0.7 units, a clinically important difference. The decrease in study home asthma triggers (evidence of mold, water damage, pests, smoking) was marginally greater than the comparison group decrease (P = .089). Except for mouse allergen, the percentage of study group allergen floor dust samples at or above the detection limit decreased, although most reductions were not statistically significant. CONCLUSIONS Combining weatherization and healthy home interventions (e.g., improved ventilation, moisture and mold reduction, carpet replacement, and plumbing repairs) with CHW asthma education significantly improves childhood asthma control.

Abstract
INTRODUCTION Connecting patients admitted with asthma to community-based services could improve care and more efficiently allocate resources. We sought to develop and evaluate an intervention to mitigate in-home environmental hazards (eg, pests, mold) for such children. METHODS This was a controlled, quality improvement study on the inpatient units of an urban, academic children's hospital. Clinicians and public health officials co-developed processes to identify children with in-home risks and refer them for assessment and remediation. Processes assessed were the rate at which those identified as eligible were offered referrals, those referred received inspections, and primary care physicians (PCPs) were notified of risks and referrals. Consecutively occurring and seasonally matched intervention (n = 30) and historical control (n = 38) subcohorts were compared with respect to postdischarge mitigating actions (eg, discussions with landlords, PCPs), remaining risks, and morbidity (symptom-free days in previous 2 weeks and Child Asthma Control Test scores). RESULTS In the first year, the percentage of eligible children offered referrals increased to a sustained rate of ∼90%; ∼65% of referrals led to in-home inspections (n = 50); and hazards were abated in 30 homes. PCP notification increased from 50% to ∼80%. After discharge, referred parents were more likely to discuss concerns with landlords, the health department, attorneys, and PCPs than patients admitted preimplementation (all P < .05). Referred households were more likely to report reduced presence of ≥2 exposures (P < .05). No differences in asthma morbidity were observed. CONCLUSIONS We integrated environmental hazard mitigation into inpatient care. Community-engaged care delivery that reduces risks for poor asthma outcomes can be initiated within the hospital.

Abstract
OBJECTIVES This program evaluation examines the outcomes of a multicomponent urban home-based asthma program implemented through a city health department in a large Midwestern city. The purpose of the program was to improve asthma outcomes by controlling indoor asthma triggers in the home environment. DESIGN AND SAMPLE This was a pre-post evaluation study. Participants received home-based education from a public health nurse or a health educator, cleaning and other supplies, and physical home interventions such as mold abatement and pest control. Asthma outcomes, caregiver quality of life, trigger-related activities, and asthma management activities at baseline and 6 months following the intervention were evaluated using survey data. A total of 115 participants for whom baseline and follow-up data were available were included in this analysis. MEASURES This study used parent self-reported quantitative and qualitative data which were collected through baseline and follow-up surveys administered by program staff. RESULTS Significant reduction in asthma symptom days, nighttime awakenings, days with activity limitation, and albuterol use were observed. Emergency department visits, missed school days, and caregiver missed work days also were significantly reduced, and caregiver quality of life improved. CONCLUSIONS This multifaceted home-based intervention decreased asthma triggers and improved asthma outcomes in children, and improved the quality of life of their caregivers.

A simulation model of building intervention impacts on indoor environmental quality, pediatric asthma, and costs. J Allergy Clin Immunol 2013; 133:77-84.

Abstract
BACKGROUND Although indoor environmental conditions can affect pediatric asthmatic patients, few studies have characterized the effect of building interventions on asthma-related outcomes. Simulation models can evaluate such complex systems but have not been applied in this context. OBJECTIVE We sought to evaluate the impact of building interventions on indoor environmental quality and pediatric asthma health care use, and to conduct cost comparisons between intervention and health care costs and energy savings. METHODS We applied our previously developed discrete event simulation model (DEM) to simulate the effect of environmental factors, medication compliance, seasonality, and medical history on (1) pollutant concentrations indoors and (2) asthma outcomes in low-income multifamily housing. We estimated health care use and costs at baseline and subsequent to interventions, and then compared health care costs with energy savings and intervention costs. RESULTS Interventions, such as integrated pest management and repairing kitchen exhaust fans, led to 7% to 12% reductions in serious asthma events with 1- to 3-year payback periods. Weatherization efforts targeted solely toward tightening a building envelope led to 20% more serious asthma events, but bundling with repairing kitchen exhaust fans and eliminating indoor sources (eg, gas stoves or smokers) mitigated this effect. CONCLUSION Our pediatric asthma model provides a tool to prioritize individual and bundled building interventions based on their effects on health and costs, highlighting the tradeoffs between weatherization, indoor air quality, and health. Our work bridges the gap between clinical and environmental health sciences by increasing physicians' understanding of the effect that home environmental changes can have on their patients' asthma.

Abstract
Health disparities are pervasive in the United States. Health and health care disparities are the differences or gaps in health (eg, life expectancy, morbidity, risk factors, and quality of life) and health care access and quality between segments of the United States population as related to race/ethnicity and socioeconomic status (eg, income, education). Multiple factors are associated with such disparities in asthma management and education. This article explores some of those factors and summarizes the strategies developed and interventions implemented to address disparities associated with asthma care and education among racial and ethnic minority children. It also discusses the need for further research to identify effective asthma education approaches for improving the management of asthma among racial and ethnic minority children. More exploration of the root causes of health care disparities, including policy studies in the area of social determinates of health and health equity, is also needed.

Abstract
OBJECTIVES Home-based, multifaceted interventions have been effective in reducing asthma morbidity in children. However, identification of independent components that contribute to outcomes and delineating effectiveness by level of asthma symptoms would help to refine the intervention and target appropriate populations. METHODS A community health educator led asthma intervention implemented in a low-income African-American neighborhood included asthma management education, individually tailored low-cost asthma home trigger remediation, and referrals to social and medical agencies, when appropriate. Changes in asthma morbidity measures were assessed in relation to implementation of individual intervention components using multivariable logistic regression. RESULTS Among the 218 children who completed the year-long program, there were significant reductions in measures of asthma morbidity, including symptoms, urgent care visits, emergency department (ED) visits, hospitalizations, missed school days, and missed work days for caretakers. We also found significant decreases in the prevalence of many home asthma triggers and improvements in asthma management practices. Improvement in caretaker's ability to manage the child's asthma was associated with reduction in ED visits for asthma and uncontrolled asthma. Specific home interventions, such as repair of water leaks and reduced exposure to plants, dust, clutter and stuffed toys, may be related to reduction in asthma morbidity. CONCLUSIONS This program was effective in reducing asthma morbidity in low-income African-American children and identified specific interventions as possible areas to target in future projects. Furthermore, the intervention was useful in children with persistent asthma symptoms as well as those with less frequent asthma exacerbations.

Abstract
Asthma imposes considerable patient and economic burdens, with the most severe cases causing the greatest affliction. Identifying stimuli that worsen asthma severity is an essential step to controlling both disease morbidity and the lessening economic impact. This study provides the first mechanistic investigation into how acute ethanol exposure will increase asthma severity in a murine model of mild cockroach allergen (CRA)-induced asthma. Outbred mice were sensitized to induce mild allergic asthma, with intratracheal CRA exposures on days 0 and 14. On day 21 mice were gavaged with water or 32% ethanol, and the third allergen exposure was given 30 min post-gavage. Asthmatic responses were measured at several time-points up to 42 h after the third allergen challenge. Ethanol-gavaged mice showed increased asthma severity within 90 min post-allergen challenge, with exacerbations lasting for 24 h. Ethanol caused greater airways obstruction, including an eightfold increase in epithelial cell mucin and increased mucus plugs, resulting in a 50% reduction in bronchiole patency. Ethanol gavage also induced significant increases in airways hyperreactivity. While T helper type 1 (Th1) and Th2 cytokines were not altered by ethanol gavage, pulmonary neutrophil and eosinophil recruitment were augmented. This increase was associated with increased chemokine production. Administration 2 h prior to ethanol gavage of a neutralizing antibody cocktail to keratinocyte-derived chemokine, macrophage inflammatory protein-2, eotaxin-1 and eotaxin-2 prevented ethanol-induced eosinophil recruitment and airways hyperreactivity. These data provide evidence that acute alcohol exposure immediately prior to a mild allergen-triggered asthmatic episode will exacerbate asthma severity mediated by increased production of chemokines.

Abstract
Evaluation of: Woods ER, Bhaumik U, Sommer SJ et al. Community asthma initiative: evaluation of a quality improvement program for comprehensive asthma care. Pediatrics 129(3), 465-472 (2012). The Community Asthma Initiative is an evidence-based asthma intervention that is effective in improving quality of life for inner-city African-American and Latino children, while showing a return on investment of US$1.46, due to lower asthma-related hospital costs. The program provides an example of a comprehensive asthma management model that could be disseminated nationally with the goal of reducing asthma disparities. The health of children disproportionately affected by asthma could also be improved by integrating a broad range of housing policies into evidence-based asthma interventions in communities with high-pediatric asthma morbidity. Such interventions will be costly, but are likely to achieve long-term sustainable health benefits for children with asthma.

Abstract
BACKGROUND Applied environmental strategies for asthma control are often expensive, but may save longer-term healthcare costs. Whether these savings outweigh additional costs of implementing these strategies is uncertain. METHODS We conducted a systematic review to estimate the expenditures and savings of environmental interventions for asthma in the state of Maryland. Direct costs included hospitalizations, emergency room, and clinic visits. Indirect expenditures included costs of lost work productivity and travel incurred during the usage of healthcare services. We used decision analysis, assuming a hypothetical cohort of the approximated 49,290 pediatric individuals in Maryland with persistent asthma, to compare costs and benefits of environmental asthma interventions against the standard of care (no intervention) from the societal perspective. RESULTS Three interventions among nine articles met the inclusion criteria for the systematic review: 1) environmental education using medical professionals; 2) education using non-medical personnel; and 3) multi-component strategy involving education with non-medical personnel, allergen-impermeable covers, and pest management. All interventions were found to be cost-saving relative to the standard of care. Home environmental education using non-medical professionals yielded the highest net savings of $14.1 million (95% simulation interval (SI): $-.283 million, $19.4 million), while the multi-component intervention resulted in the lowest net savings of $8.1 million (95% SI: $-4.9 million, $15.9 million). All strategies were most sensitive to the baseline number of hospitalizations in those not receiving targeted interventions for asthma. CONCLUSIONS Limited environmental reduction strategies for asthma are likely to be cost-saving to the healthcare system in Maryland and should be considered for broader scale-up in other economically similar settings.

Abstract
UNLABELLED Since December 2009, chest physicians and allergologists in Burgundy have been able to call upon a medical indoor environment counsellor (MIEC). The consultations are free for the patient and are undertaken following a medical referal after systematic cutaneous prick tests. AIMS To describe the indications, the distribution of prescriptions and to measure the impact of the counsellor's visits on the first 100 patients at 6 months and on the physicians at 18 months. METHOD Telephone interviews with the 67 physicians (whether prescribers or not) concerning their motivation and/or expectations, and with the first 100 patients concerning follow up of the recommendations. RESULTS Seventy percent of the physicians replied (n=47). The satisfaction of prescribers (n=22) was 8.42/10. The indications were rhinitis and a poorly controlled asthma. The requests concerned the search for dust mite (50%) and moulds (46%). Eighty-four percent of the physicians discussed the MIEC's report with the patients. The patients' symptoms were rhinitis (79%), asthma (57%) and conjunctivitis (33%). The Acarex test(®), performed in cases of positive prick tests to house dust mites (n=72), was strongly positive for 67 patients. Sixteen mould samples out of 21 were above the standard concentrations. Sixty-nine patients had followed the recommendations of the MIEC. CONCLUSION The impact of the MIEC visits was perceived as positive by the physicians and the patients. The medico-economic impact warrants further evaluation.

Abstract
OBJECTIVE This review examines the evidence for psychosocial influences in asthma and behavioral medicine approaches to its treatment. METHOD We conducted a systematic review of the literature on psychosocial influences and the evidence for behavioral interventions in asthma with a focus on research in the past 10 years and clinical trials. Additional attention was directed at promising new developments in the field. RESULTS Psychosocial factors can influence the pathogenesis and pathophysiology of asthma, either directly through autonomic, endocrine, immunological, and central nervous system mechanisms or indirectly through lifestyle factors, health behaviors, illness cognitions, and disease management, including medication adherence and trigger avoidance. The recent decade has witnessed surging interest in behavioral interventions that target the various pathways of influence. Among these, self-management training, breathing training, and exercise or physical activation programs have proved particularly useful, whereas other essential or promising interventions, such as smoking cessation, dietary programs, perception and biofeedback training, and suggestive or expressive psychotherapy, require further, more rigorous evaluation. Given the high comorbidity with anxiety and mood disorders, further evaluation of illness-specific cognitive behavior therapy is of particular importance. Progress has also been made in devising community-based and culturally tailored intervention programs. CONCLUSION In concert with an essential medication treatment, behavioral medicine treatment of asthma is moving closer toward an integrated biopsychosocial approach to disease management.

Abstract
In the past, cockroach allergen exposure assessment mainly focused on settled dust in homes in low-income urban cities in the United States. That choice was not wrong; without measureable levels of cockroach allergen, it is difficult to show associations with any home characteristics, much less with health outcomes (e.g., allergy, asthma). However, recent studies in other suburban areas, schools, and other countries have elucidated the importance of cockroach allergen in these environments too. In addition, characterizing the underlying factors that give rise to cockroach allergen exposure (or protect against it) can lead to more targeted public health interventions. This review discusses different approaches to sampling indoor environments, interprets recent asthma and allergy studies, compares cockroach allergen levels from past studies with those of recent studies, and describes strategies for decreasing exposures.

Abstract
The present review aims to identify and summarize epidemiologic investigations published during 2011 on the environmental risk factors for asthma. Potentially eligible papers were identified by a MEDLINE search. In total, 1,130 items were retrieved. Based on a broad definition of environment, the following topics were included: obesity, diet, vitamin D, air pollution, farming environment, and social factors. Some of the more relevant contributions included evidence that 1) obesity precedes asthma, 2) fruit consumption is longitudinally associated with a lower risk of asthma and atopy, 3) a comprehensive statewide smoking ban was followed by a reduction in hospital admissions for asthma, 4) asthma is one of the diseases showing the largest burdens due to environmental tobacco smoke, 5) traffic-related urban air pollution is associated with bronchial inflammation as measured by fractional exhaled nitric oxide and uncontrolled asthma, 6) aeroallergens and desert dust may contribute to the short-term effects of air pollution and asthma, and 7) maternal exposure to air pollution before and during pregnancy may alter the immune competence in offspring.

Abstract
Asthma is difficult to diagnose in the child with sickle cell disease because symptoms and pulmonary function abnormalities are similar to the spectrum of pulmonary manifestations in sickle cell disease. There are no published reports of controlled trials of asthma medications in children with sickle cell disease. Thus, treatment decisions should be guided by the Expert Panel Report 3: Guidelines for the Diagnosis and Management of Asthma (www.nhlbi.nih.gov/guidelines/asthma/asthgdln.pdf). However, issues specific to children with sickle cell disease should be considered. Initial strategies should focus on control of environmental triggers, as effectiveness on asthma outcomes is proven and the cost for implementation can be low. Use of short- and long-acting β2-agonists may prolong QTc, particularly in this population of children who already have a higher prevalence of prolonged QTc than the general population. Long-acting β2-agonist use has been associated with life-threatening asthma exacerbations with potentially higher risks in African Americans. Montelukast has been reported to increase suicidal thinking and behavior, and persons with asthma and sickle cell disease are already at risk for these events. Oral corticosteroids in the treatment of acute chest syndrome may increase risk of readmission even in children with asthma. The lack of prospective controlled trials of asthma drug treatment in children with asthma and sickle cell disease compels us to move this issue forward.

Abstract
The incidence of pediatric asthma in the United States creates a huge financial burden to the economy as well as a negative impact on child health. Identification and elimination of asthma triggers are helpful in reducing asthma exacerbations. The incidence of asthma is higher in African American and underserved populations. Improved management of pediatric asthma leads to improved school performance, improved mental health, and general well-being.

Abstract
Rapid prototyping of medically assistive mobile devices promises to fuel innovation and provides opportunity for hands-on engineering training in biomedical engineering curricula. This paper presents the design and outcomes of a course offered during a 16-week semester in Fall 2011 with 11 students enrolled. The syllabus covered a mobile health design process from end-to-end, including storyboarding, non-functional prototypes, integrated circuit programming, 3D modeling, 3D printing, cloud computing database programming, and developing patient engagement through animated videos describing the benefits of a new device. Most technologies presented in this class are open source and thus provide unlimited "hackability". They are also cost-effective and easily transferrable to other departments.

Abstract
One of the 3 goals for accountable care organizations is to improve population health. This will require that accountable care organizations bridge the schism between clinical care and public health. But do health care delivery organizations and public health agencies share a concept of "population"? We think not: whereas delivery systems define populations in terms of persons receiving care, public health agencies typically measure health on the basis of geography. This creates an attribution problem, particularly in large urban centers, where multiple health care providers often serve any given neighborhood. We suggest potential innovations that could allow urban accountable care organizations to accept accountability, and rewards, for measurably improving population health.

Abstract
BACKGROUND In the United States, asthma is the most common chronic disease of childhood across all socioeconomic classes and is the most frequent cause of hospitalization among children. Asthma exacerbations have been associated with exposure to residential indoor environmental stressors such as allergens and air pollutants as well as numerous additional factors. Simulation modeling is a valuable tool that can be used to evaluate interventions for complex multifactorial diseases such as asthma but in spite of its flexibility and applicability, modeling applications in either environmental exposures or asthma have been limited to date. METHODS We designed a discrete event simulation model to study the effect of environmental factors on asthma exacerbations in school-age children living in low-income multi-family housing. Model outcomes include asthma symptoms, medication use, hospitalizations, and emergency room visits. Environmental factors were linked to percent predicted forced expiratory volume in 1 second (FEV1%), which in turn was linked to risk equations for each outcome. Exposures affecting FEV1% included indoor and outdoor sources of NO2 and PM2.5, cockroach allergen, and dampness as a proxy for mold. RESULTS Model design parameters and equations are described in detail. We evaluated the model by simulating 50,000 children over 10 years and showed that pollutant concentrations and health outcome rates are comparable to values reported in the literature. In an application example, we simulated what would happen if the kitchen and bathroom exhaust fans were improved for the entire cohort, and showed reductions in pollutant concentrations and healthcare utilization rates. CONCLUSIONS We describe the design and evaluation of a discrete event simulation model of pediatric asthma for children living in low-income multi-family housing. Our model simulates the effect of environmental factors (combustion pollutants and allergens), medication compliance, seasonality, and medical history on asthma outcomes (symptom-days, medication use, hospitalizations, and emergency room visits). The model can be used to evaluate building interventions and green building construction practices on pollutant concentrations, energy savings, and asthma healthcare utilization costs, and demonstrates the value of a simulation approach for studying complex diseases such as asthma.

Abstract
OBJECTIVES Understanding triggers is important for managing asthma particularly for patients who seek emergency department (ED) care for exacerbations. The objectives of this analysis were to delineate self-reported triggers in ED patients and to assess associations between triggers and asthma knowledge, severity, and quality of life. METHODS At the time of an ED visit, 296 patients were asked what were their usual asthma triggers based on a checklist of 25 potential items, and what they thought specifically precipitated their current ED visit. Using standardized scales, patients also were asked about asthma knowledge, severity, and quality of life. RESULTS The mean age was 44 years and 72% were women. Patients cited a mean of 12 triggers; most patients had diverse triggers spanning respiratory infections, environmental irritants, emotions, allergens, weather, and exercise. Patients with more triggers were more likely to be women (odds ratio (OR) = 2.0, confidence interval (CI) = 1.3, 3.2, p = .002), obese (OR = 1.7, CI = 1.1, 2.5, p = .01), and to not have a smoking history (OR = 1.9, CI = 1.3, 2.9, p = .001). There were no associations between number of triggers and current age, age at diagnosis, education, socioeconomic status, or race/ethnicity. Patients who cited more triggers had more frequent flares (OR = 1.1, CI = 1.1, 1.2, p < .0001), worse quality of life scores (OR 1.6, CI = 1.1, 2.4, p = .02), and were more likely to have been previously hospitalized for asthma (OR = 1.9, CI = 1.3, 2.9, p = .003) and to have previously required oral corticosteroids (OR = 2.9, CI = 1.6, 5.1, p = .003). There was little clustering of specific triggers according to the variables we considered except for more frequent animal allergy in patients diagnosed at a younger age (OR = 2.8, CI = 1.7, 4.5, p < .0001) and worse quality of life in patients citing emotional stress as a trigger (OR = 2.5, CI = 1.5, 4.0, p = .0002). Patients attributed their current ED visit to multiple precipitants, particularly respiratory infections and weather, and these were concordant with what they reported were known triggers. CONCLUSIONS Patients presenting to the ED for asthma reported multiple triggers spanning diverse classes of precipitants and having more triggers was associated with worse clinical status. ED patients should be instructed that although it may not be possible to eliminate all triggers, mitigating even some triggers can be helpful.

Abstract
CONTEXT Asthma is a chronic respiratory disease increasingly prevalent in the U.S., particularly among children and certain minority groups. This umbrella review sought to assess and summarize existing systematic reviews of asthma-related interventions that might be carried out or supported by state or community asthma control programs, and to identify gaps in knowledge. EVIDENCE ACQUISITION Eleven databases were searched through September 2010, using terms related to four concepts: asthma, review, intervention, and NOT medication. Reviews of the effectiveness of medications, medical procedures, complementary and alternative medicine, psychological interventions, family therapy, and nutrients or nutritional supplements were excluded. Two coders screened each record and extracted data from the included reviews. EVIDENCE SYNTHESIS Data analysis was conducted from May to December 2010. Of 42 included reviews, 19 assessed the effectiveness of education and/or self-management, nine the reduction of indoor triggers, nine interventions to improve the provision of health care, and five examined other interventions. Several reviews found consistent evidence of effectiveness for self-management education, and one review determined that comprehensive home-based interventions including the reduction of multiple indoor asthma triggers are effective for children. Other reviews found limited or insufficient evidence because of study limitations. CONCLUSIONS State or community asthma control programs should prioritize (1) implementing interventions for which the present review found evidence of effectiveness and (2) evaluating promising interventions that have not yet been adequately assessed.

Economic value of home-based, multi-trigger, multicomponent interventions with an environmental focus for reducing asthma morbidity a community guide systematic review. Am J Prev Med 2011; 41:S33-47. [PMID: 21767734 DOI: 10.1016/j.amepre.2011.05.011] [Citation(s) in RCA: 59] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/17/2010] [Revised: 04/19/2011] [Accepted: 05/09/2011] [Indexed: 11/22/2022]
Abstract
CONTEXT A recent systematic review of home-based, multi-trigger, multicomponent interventions with an environmental focus showed their effectiveness in reducing asthma morbidity among children and adolescents. These interventions included home visits by trained personnel to assess the level of and reduce adverse effects of indoor environmental pollutants, and educate households with an asthma client to reduce exposure to asthma triggers. The purpose of the present review is to identify economic values of these interventions and present ranges for the main economic outcomes (e.g., program costs, benefit-cost ratios, and incremental cost-effectiveness ratios). EVIDENCE ACQUISITION Using methods previously developed for Guide to Community Preventive Services economic reviews, a systematic review was conducted to evaluate the economic efficiency of home-based, multi-trigger, multicomponent interventions with an environmental focus to improve asthma-related morbidity outcomes. A total of 1551 studies were identified in the search period (1950 to June 2008), and 13 studies were included in this review. Program costs are reported for all included studies; cost-benefit results for three; and cost-effectiveness results for another three. Information on program cost was provided with varying degrees of completeness: six of the studies did not provide a list of components included in their program cost description (limited cost information), three studies provided a list of program cost components but not a cost per component (partial cost information), and four studies provided both a list of program cost components and costs per component (satisfactory cost information). EVIDENCE SYNTHESIS Program costs per participant per year ranged from $231-$14,858 (in 2007 U.S.$). The major factors affecting program cost, in addition to completeness, were the level of intensity of environmental remediation (minor, moderate, or major), type of educational component (environmental education or self-management), the professional status of the home visitor, and the frequency of visits by the home visitor. Benefit-cost ratios ranged from 5.3-14.0, implying that for every dollar spent on the intervention, the monetary value of the resulting benefits, such as averted medical costs or averted productivity losses, was $5.30-$14.00 (in 2007 U.S.$). The range in incremental cost-effectiveness ratios was $12-$57 (in 2007 U.S.$) per asthma symptom-free day, which means that these interventions achieved each additional symptom-free day for net costs varying from $12-$57. CONCLUSIONS The benefits from home-based, multi-trigger, multicomponent interventions with an environmental focus can match or even exceed their program costs. Based on cost-benefit and cost-effectiveness studies, the results of this review show that these programs provide a good value for dollars spent on the interventions.
