BACKGROUND: In recent years, there has been a growing understanding that organizational culture is related to an organization's performance. However, few studies have examined organizational culture in medical group practices. OBJECTIVES: The purpose of this study was to examine the relationship of organizational culture on provider job satisfaction and perceived clinical effectiveness in primary care pediatric practices. RESEARCH DESIGN: This cross-sectional study included 36 primary care pediatric practices located in Connecticut. PARTICIPANTS: There were 374 participants in this study, which included 127 clinicians and 247 nonclinicians. MEASURES: Office managers completed a questionnaire that recorded staff and practice characteristics; all participants completed the Organizational Culture Scale, a questionnaire that assessed the practice on four cultural domains (i.e., group, developmental, rational, and hierarchical), and the Primary Care Organizational Questionnaire that evaluated perceived effectiveness and job satisfaction. RESULTS: Hierarchical linear models using a restricted maximum likelihood estimation method were used to evaluate whether the practice culture types predicted job satisfaction and perceived effectiveness. Group culture was positively associated with both satisfaction and perceived effectiveness. In contrast, hierarchical and rational culture were negatively associated with both job satisfaction and perceived effectiveness. These relationships were true for clinicians, nonclinicians, and the practice as a whole. CONCLUSIONS: Our study demonstrates that practice culture is associated with job satisfaction and perceived clinical effectiveness and that a group culture was associated with high job satisfaction and perceived effectiveness.

STUDY OBJECTIVES: To compare the rates of emergency department (ED) visits, hospitalizations, hospital days, and outpatient clinic visits for asthma among children in two ethnic minority groups that are disproportionately affected by asthma (Puerto Ricans and African Americans). Study design: This cross-sectional study was part of an asthma intervention program in Hartford, CT, in which 6,554 children were screened for asthma by primary care providers using a parental survey. Medicaid and the supplementary State Children's Health Insurance Plan data about health-care utilization for asthma were obtained for each child for the 12 months preceding completion of the screening survey. RESULTS: Among 2,304 children in whom asthma had been diagnosed, Puerto Ricans had more severe asthma than African Americans. In analyses adjusted for asthma severity and other potential confounders, Puerto Rican children had more clinic visits for asthma (rate ratio [RR], 1.31; 95% confidence interval [CI], 1.12 to 1.53) but spent fewer days in the hospital for asthma (RR, 0.36; 95% CI, 0.24 to 0.53) than African-American children. There were no differences in the rates of ED visits or hospitalizations between the two groups. CONCLUSIONS: Puerto Rican children had more severe asthma but were less likely than African-American children to have prolonged hospitalizations for asthma. This finding may be due to the frequent clinic visits for asthma made by Puerto Rican children. Further research is needed to understand the cultural factors that contribute to different approaches to health-care utilization among ethnic minorities. [ABSTRACT FROM AUTHOR]

Objectives: We describe the system of asthma care in Hartford, CT, an urban, minority community.Methods: The health field concept was used to organize factors influencing asthma prevalence and severity. Data were obtained from national, state, and municipal reports, and from surveys of children in Hartford seeking medical care in an asthma program called Easy Breathing.Results: Between June 1, 1998, and May 1, 2000, 21% of children receiving Medicaid in Hartford did not file a medical claim. Between 1998 and 2000, the number of providers in Hartford decreased by 37% while the number of outpatient visits increased by 8%. Using claims data, we found the following: 19.0% of Hartford children had asthma (data from the International Classification of Disease, ninth revision, and the National Drug Code); and 12% of children with asthma filled a prescription for inhaled corticosteroid therapy, 83% for a bronchodilator, and 36% for an oral corticosteroid. Children with asthma were more likely to be hospitalized (10% vs 5%, respectively) and to visit an emergency department (45% vs 29%, respectively), and, on average, they had more hospital days (0.603 vs 0.415 days per child, respectively) and more outpatient visits per year (4.7 vs 2.5 visits, respectively) compared to children without asthma. Asthma prevalence in the 6,643 children surveyed in the Easy Breathing program was 41%. Persistent asthma was diagnosed in 50% of the children with asthma. Asthma prevalence varied by ethnic origin, age, and gender, and was highest in Hispanic/Puerto Rican children, in children 5 to 10 years of age, in boys up to 10 years of age, and in girls after 15 years of age.Conclusion: Improved personal behaviors and medical care will have a limited sustained impact on childhood asthma until basic environmental issues are modified. The health field concept provides a mechanism with which to address the issues surrounding asthma in urban communities. [ABSTRACT FROM AUTHOR]

This study was undertaken to determine whether the subscale structure of an instrument used to measure parental health locus of control is a valid representation of the concept of locus of control in the Puerto Rican community. Ethnocultural differences in values and attitudes may create different conceptualizations of questionnaire items, which may impact on the subscale factor loadings for these items. Four hundred and twenty parents of Puerto Rican ethnicity living in a mainland inner city community in the United States completed the Parental Health Beliefs Scales (PHBS) instrument, which was developed to measure parental locus of control regarding their children's health. Results were subject to exploratory factor analysis. The resultant factor structure was then compared to other published factor structures by confirmatory factor analysis. Exploratory factor analysis results show a new five factor solution. Compared to two previously published factor structures for this instrument, the new five factor structure has a better goodness of fit for this Puerto Rican study sample. Through item analysis, we were able to refine the final structure into a four factor, 15 item instrument. We conclude that the new factor structure for the PHBS creates an instrument with subscales that reflect Puerto Rican cultural beliefs and values, especially as it pertains to locus of control issues (e.g. respect of professionals, collectivism, and the importance of fate). When working with ethnocultural minority groups, the health services researcher needs to be certain that the research instruments used are culturally appropriate and sensitive.

Background: The National Asthma Education and Prevention Program guidelines emphasize environmental control as an integral part of asthma management; however, limited national-level data exist on how clinicians implement environmental control recommendations., Objective: We analyzed data on clinicians' self-reported use of recommended environmental control practices in a nationally representative sample (n = 1645) of primary care physicians, asthma specialists, and advanced practice providers from the National Asthma Survey of Physicians, a supplemental questionnaire to the 2012 National Ambulatory Medical Care Survey., Methods: We examined clinician and practice characteristics as well as clinicians' decisions and strategies regarding environmental trigger assessment and environmental control across provider groups. Regression modeling was used to identify clinician and practice characteristics associated with implementation of guideline recommendations., Results: A higher percentage of specialists assessed asthma triggers at home, school, and/or work than primary care or advanced practice providers (almost always: 53.6% vs 29.4% and 23.7%, respectively, P  < .001). Almost all clinicians (>93%) recommended avoidance of secondhand tobacco smoke, whereas recommendations regarding cooking appliances (eg, proper ventilation) were infrequent. Although assessment and recommendation practices differed between clinician groups, modeling results showed that clinicians who reported almost always assessing asthma control were 5- to 6-fold more likely to assess environmental asthma triggers. Use of asthma action plans was also strongly associated with implementation of environmental control recommendations., Conclusions: Environmental assessment and recommendations to patients varied among asthma care providers. High adherence to other key guideline components, such as assessing asthma control, was associated with environmental assessment and recommendation practices on environmental control., Competing Interests: Supported in part by the Intramural Research Program of the 10.13039/100000002National Institutes of Health, the 10.13039/100000066National Institute of Environmental Health Sciences (Z01-ES-025041), and through a contract to Social & Scientific Systems funded by the National Institute of Environmental Health Sciences (HHSN273201600002I).

The use of a single inhaler containing the combination of an inhaled corticosteroid (ICS) and formoterol, a specific long-acting bronchodilator, for both maintenance and quick relief therapy (single maintenance and reliever therapy [SMART or MART]) is recommended by both the Global Initiative for Asthma and the National Asthma Education and Prevention Program Coordinating Committee in steps 3 and 4 of asthma management. This article provides practical advice about implementing SMART in clinical practice based on evidence and clinical experience. Fundamental to SMART is that ICS-formoterol provides quick relief of asthma symptoms similar to that of short-acting β 2 -agonists such as albuterol, while reducing the risk for severe asthma exacerbations and at an overall lower ICS exposure. Most SMART clinical trials were in adults and adolescents (aged ≥12 years), using budesonide-formoterol 160/4.5 μg (delivered dose), one inhalation once or twice daily (step 3) and two inhalations twice daily (step 4). For both steps 3 and 4, patients take additional inhalations of budesonide-formoterol 160/4.5 μg, one inhalation whenever needed for symptom relief, up to a maximum for adults and adolescents of 12 total inhalations in any single day (delivering 54 μg formoterol). The efficacy and safety of SMART with budesonide-formoterol and beclometasone-formoterol have been confirmed, but other ICS-long-acting bronchodilator combinations have not been studied. The SMART regimen should be introduced with a careful explanation of its role in self-management, preferably with a customized written asthma action plan. The cost to patients and the availability of SMART treatment will depend on the prescribed dose and national or local payer agreements., (Copyright © 2021 American Academy of Allergy, Asthma & Immunology.

Severe asthma exacerbations are a major cause of school absences and healthcare costs in children, particularly those in high-risk racial/ethnic groups.To identify susceptibility genes for severe asthma exacerbations in Latino children and adolescents, we conducted a meta-analysis of genome-wide association studies (GWAS) in 4010 Latino youth with asthma in four independent cohorts, including 1693 Puerto Ricans, 1019 Costa Ricans, 640 Mexicans, 256 Brazilians and 402 members of other Latino subgroups. We then conducted methylation quantitative trait locus, expression quantitative trait locus and expression quantitative trait methylation analyses to assess whether the top single nucleotide polymorphism (SNP) in the meta-analysis is linked to DNA methylation and gene expression in nasal (airway) epithelium in separate cohorts of Puerto Rican and Dutch children and adolescents.In the meta-analysis of GWAS, an SNP in FLJ22447 (rs2253681) was significantly associated with 1.55 increased odds of severe asthma exacerbation (95% CI 1.34-1.79, p=6.3×10 -9 ). This SNP was significantly associated with DNA methylation of a CpG site (cg25024579) at the FLJ22447 locus, which was in turn associated with increased expression of KCNJ2-AS1 in nasal airway epithelium from Puerto Rican children and adolescents (β=0.10, p=2.18×10 -7 ).SNP rs2253681 was significantly associated with both DNA methylation of a cis-CpG in FLJ22447 and severe asthma exacerbations in Latino youth. This may be partly explained by changes in airway epithelial expression of a gene recently implicated in atopic asthma in Puerto Rican children and adolescents ( KCNJ2-AS1 )., Competing Interests: Conflict of interest: Q.

Background: Little is known about the genetic determinants of severe asthma exacerbations., Objectives: We aimed to identify genetic variants associated with asthma hospitalizations., Methods: We conducted a genome-wide association study of asthma hospitalizations in 34,167 white British adults with asthma, 1,658 of whom had at least 1 asthma-related hospitalization. This analysis was conducted by using logistic regression under an additive genetic model with adjustment for age, sex, body mass index, smoking status, and the first 5 principal components derived from genotypic data. We then analyzed data from 2 cohorts of Latino children and adolescents for replication and conducted quantitative trait locus and functional annotation analyses., Results: At the chromosome 6p21.3 locus, the single-nucleotide polymorphism (SNP) rs56151658 (8 kb from the promoter of HLA-DQB1) was most significantly associated with asthma hospitalizations (for test allele A, odds ratio = 1.36 [95% CI = 1.22-1.52]; P = 3.11 × 10 -8 ); 21 additional SNPs in this locus were associated with asthma hospitalizations at a P value less than 1 × 10 -6 . In the replication cohorts, multiple SNPs in strong linkage disequilibrium with rs56151658 were associated with severe asthma exacerbations at a P value of .01 or less in the same direction of association as in the discovery cohort. Three HLA genes (HLA-DQA2, HLA-DRB6, and HLA-DOB) were also shown to mediate the estimated effects of the SNPs associated with asthma hospitalizations through effects on gene expression in lung tissue., Conclusions: We identified strong candidate genes for asthma hospitalizations in adults in the region for class II HLA genes through genomic, quantitative trait locus, and summary data-based mendelian randomization analyses., (Copyright © 2020 American Academy of Allergy, Asthma & Immunology.

Objective: Pediatric providers play an important role in parental and youth smoking cessation. The goal of this study was to understand smoking cessation attitudes of parents and the behaviors, confidence and self-efficacy of pediatricians related to providing smoking cessation counseling to parents and youth., Methods: A mixed methods study was conducted in a convenience sample of families (n = 1,549) and pediatric primary care clinicians (n = 95) in Connecticut using surveys and focus groups from April, 2016 to January, 2017., Results: The smoking rate (cigarettes or electronic cigarettes) among all households surveyed was 21%. Interest in quitting smoking was high (71%) and did not differ based on smoking amount, duration, type of community of residence (urban, rural, etc), or race/ethnicity. For example, compared to participants who smoked for <10 years, those who smoked ≥20 years had a similar interest in quitting (OR = 1.12; 95% CI: 0.85-1.48). Ninety percent of clinicians surveyed asked parents about their smoking behavior at least annually but 36% offered no smoking cessation counseling services or referral. Clinicians almost always reported counseling youth about the dangers of nicotine and tobacco use (99%), were more confident about counseling youth than parents (p<0.01) and reported low self-efficacy about smoking cessation and prevention counseling of parents and youth. Ninety-three percent of clinicians opined that electronic cigarettes were equally or more dangerous than cigarettes but 34% never counseled youth about the dangers of electronic cigarettes., Conclusions: Clinicians frequently screen parents about their smoking behaviors, but rarely provide smoking cessation counseling and express low confidence in this activity. Clinicians are more confident counseling youth than parents. Clinicians also recognize the dangers of electronic cigarettes, yet they infrequently counsel youth about these dangers., Competing Interests: The authors have declared that no competing interests exist.

Importance: Asthma is a major public health problem worldwide and is associated with excess morbidity, mortality, and economic costs associated with lost productivity. The National Asthma Education and Prevention Program has released the 2020 Asthma Guideline Update with updated evidence-based recommendations for treatment of patients with asthma., Objective: To report updated recommendations for 6 topics for clinical management of adolescents and adults with asthma: (1) intermittent inhaled corticosteroids (ICSs); (2) add-on long-acting muscarinic antagonists; (3) fractional exhaled nitric oxide; (4) indoor allergen mitigation; (5) immunotherapy; and (6) bronchial thermoplasty., Evidence Review: The National Heart, Lung, and Blood Advisory Council chose 6 topics to update the 2007 asthma guidelines based on results from a 2014 needs assessment. The Agency for Healthcare Research and Quality conducted systematic reviews of these 6 topics based on literature searches up to March-April 2017. Reviews were updated through October 2018 and used by an expert panel (n = 19) that included asthma content experts, primary care clinicians, dissemination and implementation experts, and health policy experts to develop 19 new recommendations using the GRADE method. The 17 recommendations for individuals aged 12 years or older are reported in this Special Communication., Findings: From 20 572 identified references, 475 were included in the 6 systematic reviews to form the evidence basis for these recommendations. Compared with the 2007 guideline, there was no recommended change in step 1 (intermittent asthma) therapy (as-needed short-acting β2-agonists [SABAs] for rescue therapy). In step 2 (mild persistent asthma), either daily low-dose ICS plus as-needed SABA therapy or as-needed concomitant ICS and SABA therapy are recommended. Formoterol in combination with an ICS in a single inhaler (single maintenance and reliever therapy) is recommended as the preferred therapy for moderate persistent asthma in step 3 (low-dose ICS-formoterol therapy) and step 4 (medium-dose ICS-formoterol therapy) for both daily and as-needed therapy. A short-term increase in the ICS dose alone for worsening of asthma symptoms is not recommended. Add-on long-acting muscarinic antagonists are recommended in individuals whose asthma is not controlled by ICS-formoterol therapy for step 5 (moderate-severe persistent asthma). Fractional exhaled nitric oxide testing is recommended to assist in diagnosis and monitoring of symptoms, but not alone to diagnose or monitor asthma. Allergen mitigation is recommended only in individuals with exposure and relevant sensitivity or symptoms. When used, allergen mitigation should be allergen specific and include multiple allergen-specific mitigation strategies. Subcutaneous immunotherapy is recommended as an adjunct to standard pharmacotherapy for individuals with symptoms and sensitization to specific allergens. Sublingual immunotherapy is not recommended specifically for asthma. Bronchial thermoplasty is not recommended as part of standard care; if used, it should be part of an ongoing research effort., Conclusions and Relevance: Asthma is a common disease with substantial human and economic costs globally. Although there is no cure or established means of prevention, effective treatment is available. Use of the recommendations in the 2020 Asthma Guideline Update should improve the health of individuals with asthma.

The 2020 Focused Updates to the Asthma Management Guidelines: A Report from the National Asthma Education and Prevention Program Coordinating Committee Expert Panel Working Group was coordinated and supported by the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health. It is designed to improve patient care and support informed decision making about asthma management in the clinical setting. This update addresses six priority topic areas as determined by the state of the science at the time of a needs assessment, and input from multiple stakeholders:A rigorous process was undertaken to develop these evidence-based guidelines. The Agency for Healthcare Research and Quality's (AHRQ) Evidence-Based Practice Centers conducted systematic reviews on these topics, which were used by the Expert Panel Working Group as a basis for developing recommendations and guidance. The Expert Panel used GRADE (Grading of Recommendations, Assessment, Development and Evaluation), an internationally accepted framework, in consultation with an experienced methodology team for determining the certainty of evidence and the direction and strength of recommendations based on the evidence. Practical implementation guidance for each recommendation incorporates findings from NHLBI-led patient, caregiver, and clinician focus groups. To assist clincians in implementing these recommendations into patient care, the new recommendations have been integrated into the existing Expert Panel Report-3 (EPR-3) asthma management step diagram format., (Published by Elsevier Inc.)

Background: Little is known about specialist-specific variations in guideline agreement and adoption., Objective: To assess similarities and differences between allergists and pulmonologists in adherence to cornerstone components of the National Asthma Education and Prevention Program's Third Expert Panel Report., Methods: Self-reported guideline agreement, self-efficacy, and adherence were assessed in allergists (n = 134) and pulmonologists (n = 99) in the 2012 National Asthma Survey of Physicians. Multivariate models were used to assess if physician and practice characteristics explained bivariate associations between specialty and "almost always" adhering to recommendations (ie, ≥75% of the time)., Results: Allergists and pulmonologists reported high guideline self-efficacy and moderate guideline agreement. Both groups "almost always" assessed asthma control (66.2%, standard error [SE] 4.3), assessed school/work asthma triggers (71.3%, SE, 3.9), and endorsed inhaled corticosteroids use (95.5%, SE 2.0). Repeated assessment of the inhaler technique, use of asthma action/treatment plans, and spirometry were lower (39.7%, SE 4.0; 30.6%, SE 3.6; 44.7%, SE 4.1, respectively). Compared with pulmonologists, more allergists almost always performed spirometry (56.6% vs 38.6%, P = .06), asked about nighttime awakening (91.9% vs 76.5%, P = .03) and emergency department visits (92.2% vs 76.5%, P = .03), assessed home triggers (70.5% vs 52.6%, P = .06), and performed allergy testing (61.8% vs 21.3%, P < .001). In multivariate analyses, practice-specific characteristics explained differences except for allergy testing., Conclusions: Overall, allergists and pulmonologists adhere to the asthma guidelines with notable exceptions, including asthma action plan use and inhaler technique assessment. Recommendations with low implementation offer opportunities for further exploration and could serve as targets for increasing guideline uptake., (Published by Elsevier Inc.)

A systematic review of pharmacogenomic studies capturing adverse drug reactions (ADRs) related to asthma medications was undertaken, and a survey of Pharmacogenomics in Childhood Asthma (PiCA) consortia members was conducted. Studies were eligible if genetic polymorphisms were compared with suspected ADR(s) in a patient with asthma, as either a primary or secondary outcome. Five studies met the inclusion criteria. The ADRs and polymorphisms identified were change in lung function tests (rs1042713), adrenal suppression (rs591118), and decreased bone mineral density (rs6461639) and accretion (rs9896933, rs2074439). Two of these polymorphisms were replicated within the paper, but none had external replication. Priorities from PiCA consortia members (representing 15 institution in eight countries) for future studies were tachycardia (SABA/LABA), adrenal suppression/crisis and growth suppression (corticosteroids), sleep/behaviour disturbances (leukotriene receptor antagonists), and nausea and vomiting (theophylline). Future pharmacogenomic studies in asthma should collect relevant ADR data as well as markers of efficacy.

Asthma imposes tremendous burden on children, families, and society. Successful management requires coordinated care among children, families, health providers, and schools. Building Bridges for Asthma Care Program, a school-centered program to coordinate care for successful asthma management, was developed, implemented, and evaluated. The program consists of five steps: (1) identify students with asthma; (2) assess asthma risk/control; (3) engage the family and student at risk; (4) provide case management and care coordination, including engagement of health-care providers; and (5) prepare for next school year. Implementation occurred in 28 schools from two large urban school districts in Colorado and Connecticut. Significant improvements were noted in the proportions of students with completed School Asthma Care Plans, a quick-relief inhaler at school, Home Asthma Action/Treatment Plans and inhaler technique ( p < .01 for all variables). Building Bridges for Asthma Care was successfully implemented extending asthma care to at-risk children with asthma through engagement of schools, health providers, and families.

Background and objectives : Although primary care clinicians provide >60% of U.S. asthma care, no nationally representative study has examined variation in adherence among primary care groups to four cornerstone domains of the Expert Panel Report-3 asthma guidelines: assessment/monitoring, patient education, environmental assessment, and medications. We used the 2012 National Asthma Survey of Physicians: National Ambulatory Medical Care Survey to compare adherence by family/general medicine practitioners (FM/GM), internists, pediatricians and Community Health Center mid-level clinicians (CHC). Methods: Adherence was self-reported ( n  = 1355 clinicians). Adjusted odds of almost always adhering to each recommendation (≥75% of the time) were estimated controlling for clinician/practice characteristics, and agreement and self-efficacy with guideline recommendations. Results: A higher percentage of pediatricians adhered to most assessment/monitoring recommendations compared to FM/GM and other groups (e.g. 71.6% [SE 4.0] almost always assessed daytime symptoms versus 50.6% [SE 5.1]-51.1% [SE 5.8], t -test p  < 0.05) but low percentages from all groups almost always performed spirometry (6.8% [SE 2.0]-16.8% [SE 4.7]). Pediatricians were more likely to provide asthma action/treatment plans than FM/GM and internists. Internists were more likely to assess school/work triggers than pediatricians and CHC (environmental assessment). All groups prescribed inhaled corticosteroids for daily control (84.0% [SE 3.7]-90.7% [SE 2.5]) (medications). In adjusted analyses, pediatric specialty, high self-efficacy and frequent specialist referral were associated with high adherence. Conclusions: Pediatricians were more likely to report high adherence than other clinicians. Self- efficacy and frequent referral were also associated with adherence. Adherence was higher for history-taking recommendations and lower for recommendations involving patient education, equipment and expertise.

Objective: Effective asthma management at school can help students with asthma stay healthy, learn better and participate fully during their school day. This study sought to understand school-based asthma care from the perspective of parents and school personnel to improve asthma care at school. Methods: A cross-sectional study was conducted in Hartford, CT. School personnel from 59 schools and 322 parents/guardians were invited to participate. Four cross-sectional surveys using Likert-type scales assessed parental and school personnel satisfaction, confidence in managing asthma, policy awareness, management of asthma during physical activity, and perceived gaps surrounding school-based asthma care. Results: 263/322 (82%) eligible parents of children with asthma (mean age 8.5 ± 4.3, 56% Hispanic, 30% African American) completed surveys. Thirty six school nurses (62%), 131 teachers (8%), 14 coaches (14%), and 17 school principals (29%) participated. 90% of parents were satisfied with asthma management in school. School nurses were more aware of asthma policies than teachers (74% vs. 24%, p  < 0.001). 34% of school nurses, 30% of teachers and 36% of coaches were unaware of asthma-related absences. 14% of physical education teachers/coaches reported no asthma training. Conclusion: In this convenience sample of parents and school personnel, parents reported overall satisfaction regarding the asthma care their children receive at school, yet a number of gaps pertaining to school-based asthma care were identified. Increased asthma training and enhanced communication among school personnel is needed to address these gaps. National guidelines and resources are readily available to improve asthma care at school.

Objective: To evaluate whether school nurses can assist pediatricians in providing asthma care and reduce school absenteeism through a program called Easy Breathing for Schools (EzBfS), a 5-element school nurse-led asthma management program and the effectiveness in reducing school absenteeism., Methods: Fifteen public school nurses in an urban community implemented EzBfS during the 2015-16 and 2016-17 school years. Program elements included assessment of asthma risk and asthma control, asthma education, medication review, and a pediatrician communication tool. School absence for any reason was the primary outcome; absentee rates for students with asthma enrolled in the program were compared to students with asthma in the entire school population using negative binomial regression., Results: School nurses enrolled 251/2,126 students with physician-confirmed asthma (2015-16: n = 114 and 2016-17: n = 137). Sixty eight percent of participants were Latino and 25% were Black with a mean age of 8.7 ± 2.2 years. Absentee rates were higher in children with asthma compared to children without asthma (8.3% vs 7.0% absent, respectively P < .001). Students enrolled in the program experienced a 25% decrease in absentee rate after adjusting for age, sex, race/ethnicity, and school year (rate ratio = 0.75, 95% confidence interval, 0.67, 0.85) as compared to students with asthma not enrolled in the program. Participants also demonstrated improvement in inhaler technique score (P < .001). Ninety two percent of the nurses were satisfied with the program., Conclusion: EzBfS, a pragmatic, nurse-led asthma management program, was successfully implemented by school nurses and significantly decreased school absences among a sample of students with asthma., (Copyright © 2019 Academic Pediatric Association.

Background: Asthma is a common respiratory disorder with a highly heterogeneous nature that remains poorly understood. The objective was to use whole genome sequencing (WGS) data to identify regions of common genetic variation contributing to lung function in individuals with a diagnosis of asthma., Methods: WGS data were generated for 1,053 individuals from trios and extended pedigrees participating in the family-based Genetic Epidemiology of Asthma in Costa Rica study. Asthma affection status was defined through a physician's diagnosis of asthma, and most participants with asthma also had airway hyperresponsiveness (AHR) to methacholine. Family-based association tests for single variants were performed to assess the associations with lung function phenotypes., Results: A genome-wide significant association was identified between baseline FEV 1 /FVC ratio and a single-nucleotide polymorphism in the top hit cysteine-rich secretory protein LCCL domain-containing 2 (CRISPLD2) (rs12051168; P = 3.6 × 10 -8 in the unadjusted model) that retained suggestive significance in the covariate-adjusted model (P = 5.6 × 10 -6 ). Rs12051168 was also nominally associated with other related phenotypes: baseline FEV 1 (P = 3.3 × 10 -3 ), postbronchodilator (PB) FEV 1 (7.3 × 10 -3 ), and PB FEV 1 /FVC ratio (P = 2.7 × 10 -3 ). The identified baseline FEV 1 /FVC ratio and rs12051168 association was meta-analyzed and replicated in three independent cohorts in which most participants with asthma also had confirmed AHR (combined weighted z-score P = .015) but not in cohorts without information about AHR., Conclusions: These findings suggest that using specific asthma characteristics, such as AHR, can help identify more genetically homogeneous asthma subgroups with genotype-phenotype associations that may not be observed in all children with asthma. CRISPLD2 also may be important for baseline lung function in individuals with asthma who also may have AHR., (Copyright © 2019 American College of Chest Physicians. Published by Elsevier Inc.

Women and children belonging to a racial/ethnic minority bear a disproportionate burden of psychosocial stress that increases their vulnerability to adverse health outcomes. Hair cortisol has been rapidly advanced as a biomarker of the intensity and course of the stress response over time and may provide an opportunity to increase our understanding of the role of psychological stress in health. However, research on the link between hair cortisol levels and subjective measures of maternal and child stress among low-income and minority individuals is limited. The goal of this study was to examine the association between stress and hair cortisol in low income, minority women and children who experience disproportionate exposure to chronic stress. A convenience sample of 54 minority mother/child dyads from a busy primary care clinic in the second poorest medium-sized city in the US participated in the study. Mothers self-reported perceived stress, social support, household characteristics and other demographic factors, and their children (ages 7-14 years) reported on the perceived level of safety in their neighborhood and exposure to violence as markers of child stress. Three-centimeter hair samples were collected from both mothers and children during the clinic visit, and hair cortisol levels were assessed via enzyme-linked immunosorbent assays. Linear regression models examined associations between maternal and child hair cortisol, and between hair cortisol and perceived stress level in women, and moderation by social support. Maternal hair cortisol was not significantly associated with mother's perceived stress. Maternal and child hair cortisol levels were positively associated ( p  = .007) but this association was not moderated by maternal perceived social support. These findings suggest that hair cortisol is strongly associated among this sample of minority mother-child dyads and is not moderated by social support.

Objectives: To determine if children with congenital heart disease (CHD) have lower newborn T-cell receptor excision circles (TREC) levels than the general population and to evaluate if low TREC levels in newborns with CHD are associated with clinical complications such as hospitalization for infection., Study Design: The Connecticut Newborn Screening Program reported TREC levels for newborns with CHD delivered between October 2011 and September 2016 at 2 major Connecticut children's hospitals. TREC levels for children with CHD were compared with the general population. TREC levels and outcome measures, including hospitalization for infection, were compared., Results: We enrolled 575 participants with CHD in the study. The median TREC level for newborns with CHD was lower than the general population (180.1 copies/μL vs 312.5 copies/μL; P < .01). patients with CHD requiring hospitalization for infection had lower median TREC levels than their counterparts (143.0 copies/μL vs 186.7 copies/μL; P < .01). The combination of prematurity and low TREC level had a strong relationship to hospitalization for infection (area under the receiver operative characteristic curve of 0.89). There was no association between TREC level and CHD severity., Conclusions: Newborns with CHD demonstrated lower TREC levels than the general population. Low TREC levels were associated with hospitalization for infection in preterm children with CHD. Study limitations include that this was a retrospective chart review. These findings may help to identify newborns with CHD at highest risk for infection, allowing for potential opportunities for intervention., (Copyright © 2019 Elsevier Inc. All rights reserved.)

Pediatric asthma, the most common chronic disease of childhood, remains a significant burden to the health care system. Although there are guidelines for the management of pediatric asthma, there remain several controversies about how best to manage asthma in the primary care setting, and how to prevent asthma exacerbations and subsequent emergency department visits and hospitalizations. In this article, we address four of these controversies: use of written asthma treatment plans, the role of long-acting beta-agonists, spirometry and peak flow measurements in disease management, and engagement of school nurses in the health care team. We provide suggestions and guidance related to these topics for the pediatric primary care provider. [Pediatr Ann. 2019;48(3):e128-e134.]., (Copyright 2019, SLACK Incorporated.)

Background: Children with asthma are at increased risk for experiencing health and educational disparities because of increased school absence. School nurses are well positioned to support asthma management and improve school attendance., Objective: We sought to implement and assess the effect of the Building Bridges for Asthma Care Program on improving school attendance and measures of asthma control., Methods: Children with asthma (age, 5-14 years) in the Denver Public School System (n = 240) and the Hartford Public School System (n = 223) were enrolled in the Building Bridges Program during the 2013-2014 and 2014-2015 school years and followed until the end of the second school year. The primary outcome was school absence, with secondary outcomes, including asthma control, measured based on Childhood Asthma Control Test or the Asthma Control Test scores and rescue inhaler use., Results: Participants experienced a 22% absolute decrease in school absenteeism, the number of children with an Asthma Control Test/Childhood Asthma Control Test score of less than the control threshold of 20 decreased from 42.7% to 28.8%, and bronchodilator use greater than 2 times per week decreased from 35.8% to 22.9% (all changes were significant, P < .01)., Conclusions: Children enrolled in the Building Bridges for Asthma Care Program experienced reduced school absence and improved asthma control., (Copyright © 2018 American Academy of Allergy, Asthma & Immunology.

Background: Obesity is a major and worldwide health problem in children., Objectives: The Early Childhood Obesity Prevention Program is a multi-component, randomized, controlled trial of a pilot community-focused obesity prevention program for mother/newborn dyads., Methods: Underserved, mother/newborn dyads were recruited to receive a standard home visitation program (Nurturing Families Network, NFN) or an enhanced program (NFN+) that incorporated behavioural change strategies (e.g., goal-setting, problem-solving) and focused on six obesity-associated behaviours (breastfeeding, juice/sugar-sweetened beverages, solids, infant sleep, TV/screen time and soothability) with linkages to community resources. Weight-for-length (WFL) z-score and maternal diet were secondary outcomes., Results: Fifty-seven dyads were recruited and 47 fully eligible dyads were enrolled (NFN = 21, NFN+ = 26). Forty-one (87.2%) were assessed at 6 months and 34 (72.3%) at 12 months. Retention at 12 months was higher for NFN+ dyads (84.6% vs. 56.1%, p = 0.04). NFN+ mothers were more likely to continue breastfeeding at 6 and 12 months vs. NFN mothers (p = 0.03 and 0.003, respectively), and at 12 months, NFN+ infants had fewer nocturnal awakenings (p = 0.04). There were no differences in other primary outcome measures or in WFL z-score at 6 or 12 months., Conclusions: A multi-component behavioural intervention increased breastfeeding duration and decreased nocturnal awakenings in infants of low-income families., (© 2018 World Obesity Federation.)

Background: The 2007 Guidelines for the Diagnosis and Management of Asthma provide evidence-based recommendations to improve asthma care. Limited national-level data are available about clinician agreement and adherence to these guidelines., Objective: To assess clinician-reported adherence with specific guideline recommendations, as well as agreement with and self-efficacy to implement guidelines., Methods: We analyzed 2012 National Asthma Survey of Physicians data for 1412 primary care clinicians and 233 asthma specialists about 4 cornerstone guideline domains: asthma control, patient education, environmental control, and pharmacologic treatment. Agreement and self-efficacy were measured using Likert scales; 2 overall indices of agreement and self-efficacy were compiled. Adherence was compared between primary care clinicians and asthma specialists. Logistic regression models assessed the association of agreement and self-efficacy indices with adherence., Results: Asthma specialists expressed stronger agreement, higher self-efficacy, and greater adherence with guideline recommendations than did primary care clinicians. Adherence was low among both groups for specific core recommendations, including written asthma action plan (30.6% and 16.4%, respectively; P < .001); home peak flow monitoring, (12.8% and 11.2%; P = .34); spirometry testing (44.7% and 10.8%; P < .001); and repeated assessment of inhaler technique (39.7% and 16.8%; P < .001). Among primary care clinicians, greater self-efficacy was associated with greater adherence. For specialists, self-efficacy was associated only with increased odds of spirometry testing. Guideline agreement was generally not associated with adherence., Conclusions: Agreement with and adherence to asthma guidelines was higher for specialists than for primary care clinicians, but was low in both groups for several key recommendations. Self-efficacy was a good predictor of guideline adherence among primary care clinicians but not among specialists., (Published by Elsevier Inc.)

Obesity rates in preschool children are high and disproportionately affect low-income children of color in the USA. Since 80% of preschool children spend ∼40 h/week in out-of-the home childcare, childcare centers are promising sites for obesity prevention interventions. Mixed methods were used to develop, implement, and assess the feasibility of an obesity prevention program for children 2-5 years. The intervention which consisted of brief (1-3 min), interactive, educational modules was developed by content experts and parents (n = 20) and targeted four areas (milk, sugar sweetened beverages, screen time, and physical activity). The modules were delivered by community health workers in the childcare center during pick-up and drop-off times, in small groups and home visits upon request. Focus groups with childcare center staff (n = 28) assessed satisfaction and interest in incorporating the intervention into care. Between February 2013 and March 2014, 354 caregivers (∼73%) at six centers participated in one or more educational sessions. Of children, 37.4% in 2013 and 35.9% in 2014 were overweight or obese. Children entering preschool in 2014 were more likely to be overweight/obese than children who had been in the center since 2013 (36.2 vs 23.2%, p < 0.05). Childcare staff endorsed the intervention and received training to continue the program. Brief, interactive health-related behavior-change interventions engaged large numbers of low-income caregivers at childcare centers and resonated with center staff. Childcare center staff represent an underutilized resource to combat the childhood obesity epidemic.

Childhood asthma is a complex disease. In this study, we aim to identify genes associated with childhood asthma through a multiomics "vertical" approach that integrates multiple analytical steps using linear and logistic regression models. In a case-control study of childhood asthma in Puerto Ricans (n = 1,127), we used adjusted linear or logistic regression models to evaluate associations between several analytical steps of omics data, including genome-wide (GW) genotype data, GW methylation, GW expression profiling, cytokine levels, asthma-intermediate phenotypes, and asthma status. At each point, only the top genes/single-nucleotide polymorphisms/probes/cytokines were carried forward for subsequent analysis. In step 1, asthma modified the gene expression-protein level association for 1,645 genes; pathway analysis showed an enrichment of these genes in the cytokine signaling system (n = 269 genes). In steps 2-3, expression levels of 40 genes were associated with intermediate phenotypes (asthma onset age, forced expiratory volume in 1 second, exacerbations, eosinophil counts, and skin test reactivity); of those, methylation of seven genes was also associated with asthma. Of these seven candidate genes, IL5RA was also significant in analytical steps 4-8. We then measured plasma IL-5 receptor α levels, which were associated with asthma age of onset and moderate-severe exacerbations. In addition, in silico database analysis showed that several of our identified IL5RA single-nucleotide polymorphisms are associated with transcription factors related to asthma and atopy. This approach integrates several analytical steps and is able to identify biologically relevant asthma-related genes, such as IL5RA. It differs from other methods that rely on complex statistical models with various assumptions.

Background: Childhood asthma is likely the result of gene-by-environment (G × E) interactions. Dust mite is a known risk factor for asthma morbidity. Yet, there have been no genome-wide G × E studies of dust mite allergen on asthma-related phenotypes., Objective: We sought to identify genetic variants whose effects on lung function in children with asthma are modified by the level of dust mite allergen exposure., Methods: A genome-wide interaction analysis of dust mite allergen level and lung function was performed in a cohort of Puerto Rican children with asthma (Puerto Rico Genetics of Asthma and Lifestyle [PRGOAL]). Replication was attempted in 2 independent cohorts, the Childhood Asthma Management Program (CAMP) and the Genetics of Asthma in Costa Rica Study., Results: Single nucleotide polymorphism (SNP) rs117902240 showed a significant interaction effect on FEV 1 with dust mite allergen level in PRGOAL (interaction P = 3.1 × 10 -8 ), and replicated in the same direction in CAMP white children and CAMP Hispanic children (combined interaction P = .0065 for replication cohorts and 7.4 × 10 -9 for all cohorts). Rs117902240 was positively associated with FEV 1 in children exposed to low dust mite allergen levels, but negatively associated with FEV 1 in children exposed to high levels. This SNP is on chromosome 8q24, adjacent to a binding site for CCAAT/enhancer-binding protein beta, a transcription factor that forms part of the IL-17 signaling pathway. None of the SNPs identified for FEV 1 /forced vital capacity replicated in the independent cohorts., Conclusions: Dust mite allergen exposure modifies the estimated effect of rs117902240 on FEV 1 in children with asthma. Analysis of existing data suggests that this SNP may have transcription factor regulatory functions., (Copyright © 2017 American Academy of Allergy, Asthma & Immunology. Published by Elsevier Inc.

Objectives: Mobile technology for childhood asthma can provide real-time data to enhance care. What real-time adherence information clinicians want, how they may use it, and if the data meet their clinical needs have not been fully explored. Our goal was to determine whether pediatric primary care and pulmonary clinicians believe if a sensor-based mobile intervention is useful in caring for patients with asthma., Methods: We recruited participants from 3 urban, primary care and 1 pulmonary practice from July to September 2015 in Hartford, CT. Forty-one participated in four focus groups, which included a demonstration of the technology. Participants were probed with open-ended questions on the type, frequency, and format of inter-visit patient information they found useful., Results: 41 participants (mean age 49 (±13.7) years) were board-certified clinicians (41% MDs and 20% mid-level practitioners), practiced medicine on an average of 19 (±14) years, were primarily white (59%) and women (78%). Clinicians wanted 1) adherence to prescribed inhaler therapy and 2) data on inhaler technique. Clinicians wanted it at the time of a scheduled clinic visit but also wanted inter-visit alerts for excessive use of rescue therapy. Pulmonologists liked the mobile spirometer's provision of inter-visit lung function data; pediatricians did not share this view. Concerns with data accuracy were raised due to families who shared inhalers, access to smartphones, and protection of health information., Conclusions: Overall, clinicians view an asthma mobile health technology as enhancing the patient-centered medical home. Pediatric primary care clinicians and pulmonologists want different information from a mobile app.

Aim: International collaboration is needed to enable large-scale pharmacogenomics studies in childhood asthma. Here, we describe the design of the Pharmacogenomics in Childhood Asthma (PiCA) consortium., Materials & Methods: Investigators of each study participating in PiCA provided data on the study characteristics by answering an online questionnaire., Results: A total of 21 studies, including 14,227 children/young persons (58% male), from 12 different countries are currently enrolled in the PiCA consortium. Fifty six percent of the patients are Caucasians. In total, 7619 were inhaled corticosteroid users. Among patients from 13 studies with available data on asthma exacerbations, a third reported exacerbations despite inhaled corticosteroid use. In the future pharmacogenomics studies within the consortium, the pharmacogenomics analyses will be performed separately in each center and the results will be meta-analyzed., Conclusion: PiCA is a valuable platform to perform pharmacogenetics studies within a multiethnic pediatric asthma population.

Puerto Ricans are disproportionately affected with asthma in the USA. In this study, we aim to identify genetic variants that confer susceptibility to asthma in Puerto Ricans.We conducted a meta-analysis of genome-wide association studies (GWAS) of asthma in Puerto Ricans, including participants from: the Genetics of Asthma in Latino Americans (GALA) I-II, the Hartford-Puerto Rico Study and the Hispanic Community Health Study. Moreover, we examined whether susceptibility loci identified in previous meta-analyses of GWAS are associated with asthma in Puerto Ricans.The only locus to achieve genome-wide significance was chromosome 17q21, as evidenced by our top single nucleotide polymorphism (SNP), rs907092 (OR 0.71, p=1.2×10 -12 ) at IKZF3 Similar to results in non-Puerto Ricans, SNPs in genes in the same linkage disequilibrium block as IKZF3 ( e.g. ZPBP2 , ORMDL3 and GSDMB ) were significantly associated with asthma in Puerto Ricans. With regard to results from a meta-analysis in Europeans, we replicated findings for rs2305480 at GSDMB , but not for SNPs in any other genes. On the other hand, we replicated results from a meta-analysis of North American populations for SNPs at IL1RL1 , TSLP and GSDMB but not for IL33 Our findings suggest that common variants on chromosome 17q21 have the greatest effects on asthma in Puerto Ricans., Competing Interests: Conflict of interest: Disclosures can be found alongside this article at erj.ersjournals.com, (Copyright ©ERS 2017.)

Objective: To determine whether secondhand smoke (SHS) exposure is associated with greater asthma severity in children with physician-diagnosed asthma living in CT, and to examine whether area of residence, race/ethnicity or poverty moderate the association., Methods: A large childhood asthma database in CT (Easy Breathing) was linked by participant zip code to census data to classify participants by area of residence. Multinomial logistic regression models, adjusted for enrollment date, sex, age, race/ethnicity, area of residence, insurance type, family history of asthma, eczema, and exposure to dogs, cats, gas stove, rodents and cockroaches were used to examine the association between self-reported exposure to SHS and clinician-determined asthma severity (mild, moderate, and severe persistent vs. intermittent asthma)., Results: Of the 30,163 children with asthma enrolled in Easy Breathing, between 6 months and 18 years old, living in 161 different towns in CT, exposure to SHS was associated with greater asthma severity (adjusted relative risk ratio (aRRR): 1.07 [1.00, 1.15] and aRRR: 1.11 [1.02, 1.22] for mild and moderate persistent asthma, respectively). The odds of Black and Puerto Rican/Hispanic children with asthma being exposed to SHS were twice that of Caucasian children. Though the odds of SHS exposure for publicly insured children with asthma were three times greater than the odds for privately insured children (OR: 3.02 [2.84,3,21]), SHS exposure was associated with persistent asthma only among privately insured children (adjusted odds ratio (aOR): 1.23 [1.11,1.37])., Conclusion: This is the first large-scale pragmatic study to demonstrate that children exposed to SHS in Connecticut have greater asthma severity, clinically determined using a systematic approach, and varies by insurance status.

Rationale: For unclear reasons, obese children with asthma have higher morbidity and reduced response to inhaled corticosteroids., Objectives: To assess whether childhood obesity is associated with airway dysanapsis (an incongruence between the growth of the lungs and the airways) and whether dysanapsis is associated with asthma morbidity., Methods: We examined the relationship between obesity and dysanapsis in six cohorts of children with and without asthma, as well as the relationship between dysanapsis and clinical outcomes in children with asthma. Adjusted odds ratios (ORs) were calculated for each cohort and in a combined analysis of all cohorts; longitudinal analyses were also performed for cohorts with available data. Hazard ratios (HRs) for clinical outcomes were calculated for children with asthma in the Childhood Asthma Management Program., Measurements and Main Results: Being overweight or obese was associated with dysanapsis in both the cross-sectional (OR, 1.95; 95% confidence interval [CI], 1.62-2.35 [for overweight/obese compared with normal weight children]) and the longitudinal (OR, 4.31; 95% CI, 2.99-6.22 [for children who were overweight/obese at all visits compared with normal weight children]) analyses. Dysanapsis was associated with greater lung volumes (FVC, vital capacity, and total lung capacity) and lesser flows (FEV 1 and forced expiratory flow, midexpiratory phase), and with indicators of ventilation inhomogeneity and anisotropic lung and airway growth. Among overweight/obese children with asthma, dysanapsis was associated with severe disease exacerbations (HR, 1.95; 95% CI, 1.38-2.75) and use of systemic steroids (HR, 3.22; 95% CI, 2.02-5.14)., Conclusions: Obesity is associated with airway dysanapsis in children. Dysanapsis is associated with increased morbidity among obese children with asthma and may partly explain their reduced response to inhaled corticosteroids.

Background: Many advances in health care fail to reach patients. Implementation science is the study of novel approaches to mitigate this evidence-to-practice gap., Methods: The American Thoracic Society (ATS) created a multidisciplinary ad hoc committee to develop a research statement on implementation science in pulmonary, critical care, and sleep medicine. The committee used an iterative consensus process to define implementation science and review the use of conceptual frameworks to guide implementation science for the pulmonary, critical care, and sleep community and to explore how professional medical societies such as the ATS can promote implementation science., Results: The committee defined implementation science as the study of the mechanisms by which effective health care interventions are either adopted or not adopted in clinical and community settings. The committee also distinguished implementation science from the act of implementation. Ideally, implementation science should include early and continuous stakeholder involvement and the use of conceptual frameworks (i.e., models to systematize the conduct of studies and standardize the communication of findings). Multiple conceptual frameworks are available, and we suggest the selection of one or more frameworks on the basis of the specific research question and setting. Professional medical societies such as the ATS can have an important role in promoting implementation science. Recommendations for professional societies to consider include: unifying implementation science activities through a single organizational structure, linking front-line clinicians with implementation scientists, seeking collaborations to prioritize and conduct implementation science studies, supporting implementation science projects through funding opportunities, working with research funding bodies to set the research agenda in the field, collaborating with external bodies responsible for health care delivery, disseminating results of implementation science through scientific journals and conferences, and teaching the next generation about implementation science through courses and other media., Conclusions: Implementation science plays an increasingly important role in health care. Through support of implementation science, the ATS and other professional medical societies can work with other stakeholders to lead this effort.

Clinicians who care for children with asthma have an obligation to coordinate asthma care with the schools. Aside from routine clinical care of asthmatic children, providers must educate the family and child about the need for an asthma treatment plan in school and support the school nurse meeting the needs of the student requiring school-based asthma care. The following article was developed by multiple stakeholders to address this need. It describes the 4 components of the School-based Asthma Management Program (SAMPRO™). SAMPRO™ details elements necessary for the education of children, families, clinicians, and school-based personnel based on a "circle of support" that would enhance multidirectional communication and promote better care for children with asthma within the school setting., Competing Interests: of potential conflict of interest: R.

Epidemiologic evidence suggests that N-acetyl-para-aminophenol (APAP) may play a role in the pathogenesis of asthma, likely through pro-oxidant mechanisms. However, no studies have investigated the direct effects of APAP on the development of allergic inflammation. To determine the likelihood of a causal relationship between APAP and asthma pathogenesis, we explored the effects of APAP on inflammatory responses in a murine house dust mite (HDM) model of allergic airway disease. We hypothesized that APAP would enhance the development of HDM-induced allergic inflammation. The HDM model consisted of once daily intranasal instillations for up to 2 weeks with APAP or vehicle administration 1 hour prior to HDM during either week 1 or 2. Primary assessment of inflammation included bronchoalveolar lavage (BAL), cytokine expression in lung tissue, and histopathology. Contrary to our hypothesis, the effects of HDM treatment were substantially diminished in APAP-treated groups compared with controls. APAP-treated groups had markedly reduced airway inflammation: including decreased inflammatory cells in the BAL fluid, lower cytokine expression in lung tissue, and less perivascular and peribronchiolar immune cell infiltration. The anti-inflammatory effect of APAP was not abrogated by an inhibitor of cytochrome P450 (P450) metabolism, suggesting that the effect was due to the parent compound or a non-P450 generated metabolite. Taken together, our studies do not support the biologic plausibility of the APAP hypothesis that APAP use may contribute to the causation of asthma. Importantly, we suggest the mechanism by which APAP modulates airway inflammation may provide novel therapeutic targets for asthma., (Copyright © 2016 by The American Society for Pharmacology and Experimental Therapeutics.)

Background: Exposure to gun violence and African ancestry have been separately associated with increased risk of asthma in Puerto Rican children., Objective: The objective of this study was to examine whether African ancestry and gun violence interact on asthma and total IgE in school-aged Puerto Rican children., Methods: This is a case-control study of 747 Puerto Rican children aged 9 to 14 years living in San Juan, Puerto Rico (n = 472), and Hartford, Connecticut (n = 275). Exposure to gun violence was defined as the child's report of hearing gunshots more than once, and the percentage of African ancestry was estimated using genome-wide genotypic data. Asthma was defined as parental report of physician-diagnosed asthma and wheeze in the previous year. Serum total IgE (IU/mL) was measured in study participants. Multivariate logistic and linear regressions were used for the analysis of asthma and total IgE, respectively., Results: In multivariate analyses, there was a significant interaction between exposure to gun violence and African ancestry on asthma (P = .001) and serum total IgE (P = .04). Among children exposed to gun violence, each quartile increase in the percentage of African ancestry was associated with approximately 45% higher odds of asthma (95% CI, 1.15-1.84; P = .002) and an approximately 19% increment in total IgE (95% , 0.60-40.65, P = .04). In contrast, there was no significant association between African ancestry and asthma or total IgE in children not exposed to gun violence., Conclusions: Our results suggest that exposure to gun violence modifies the estimated effect of African ancestry on asthma and atopy in Puerto Rican children., (Copyright © 2016 American College of Chest Physicians.

Purpose of Review: This article reviews new approaches, facilitators, barriers, and opportunities to increasing guideline-adherent care for children with asthma by primary care clinicians., Recent Findings: Primary care clinicians are challenged by the volume of guidelines and want transparent guidelines that are easy to use and that can be used in complex patients with multiple comorbidities. Programs that use decision support tools and electronic technologies and provide support from individuals new to the medical home such as panel management assistants, community health workers, patient advocates, practice facilitators, school nurses, and pharmacists may enhance use of guidelines by primary care clinicians and reduce asthma morbidity. Primary care clinician burnout and difficulty incorporating electronic asthma decision tools into current workflow are recently recognized barriers to guideline integration and improved asthma outcomes. In addition, many of these interventions are labor intensive, costly and may not be capable of being widely disseminated., Summary: Programs that simplify guidelines, provide decision support tools and use electronic technologies and an expanded medical team may improve the quality of asthma care provided by the primary care community to children and their families with asthma.

To advance implementation research (IR) in respiratory, sleep, and critical care medicine, the American Thoracic Society and the Division of Lung Diseases from the NHLBI cosponsored an Implementation Research Workshop on May 17, 2014. The goals of IR are to understand the barriers and facilitators of integrating new evidence into healthcare practices and to develop and test strategies that systematically target these factors to accelerate the adoption of evidence-based care. Throughout the workshop, presenters provided examples of IR that focused on the rate of adoption of evidence-based practices, the feasibility and acceptability of interventions to patients and other stakeholders who make healthcare decisions, the fidelity with which practitioners use specific interventions, the effects of specific barriers on the sustainability of an intervention, and the implications of their research to inform policies to improve patients' access to high-quality care. During the discussions that ensued, investigators' experience led to recommendations underscoring the importance of identifying and involving key stakeholders throughout the research process, ensuring that those who serve as reviewers understand the tenets of IR, managing staff motivation and turnover, and tackling the challenges of scaling up interventions across multiple settings.

Asthma is a common chronic disease without cure. Our understanding of asthma onset, pathobiology, classification, and management has evolved substantially over the past decade; however, significant asthma-related morbidity and excess healthcare use and costs persist. To address this important clinical condition, the NHLBI convened a group of extramural investigators for an Asthma Research Strategic Planning workshop on September 18-19, 2014, to accelerate discoveries and their translation to patients. The workshop focused on (1) in utero and early-life origins of asthma, (2) the use of phenotypes and endotypes to classify disease, (3) defining disease modification, (4) disease management, and (5) implementation research. This report summarizes the workshop and produces recommendations to guide future research in asthma.
