Pediatr Allergy Immunol 2023; 34:e14032. [PMID: 37877849 DOI: 10.1111/pai.14032] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Revised: 09/12/2023] [Accepted: 09/20/2023] [Indexed: 10/26/2023]
Abstract
BACKGROUND Identifying children at high risk of developing asthma can facilitate prevention and early management strategies. We developed a prediction model of children's asthma risk using objectively collected population-based children and parental histories of comorbidities. METHODS We conducted a retrospective population-based cohort study using administrative data from Manitoba, Canada, and included children born from 1974 to 2000 with linkages to ≥1 parent. We identified asthma and prior comorbid condition diagnoses from hospital and outpatient records. We used two machine-learning models: least absolute shrinkage and selection operator (LASSO) logistic regression (LR) and random forest (RF) to identify important predictors. The predictors in the base model included children's demographics, allergic conditions, respiratory infections, and parental asthma. Subsequent models included additional multiple comorbidities for children and parents. RESULTS The cohort included 195,666 children: 51.3% were males and 17.7% had asthma diagnosis. The base LR model achieved a low predictive performance with sensitivity of 0.47, 95% confidence interval (0.45-0.48), and specificity of 0.67 (0.66-0.67) using a predicted probability threshold of 0.20. Sensitivity significantly improved when children's comorbidities were included using LASSO LR: 0.71 (0.69-0.72). Predictive performance further improved by including parental comorbidities (sensitivity = 0.72 [0.70-0.73], specificity = 0.69 [0.69-0.70]). We observed similar results for the RF models. Children's menstrual disorders and mood and anxiety disorders, parental lipid metabolism disorders and asthma were among the most important variables that predicted asthma risk. CONCLUSION Including children and parental comorbidities to children's asthma prediction models improves their accuracy.

Abstract
This study aimed to analyze the therapeutic effect of nanomedicine on bronchial asthma and the effect of vitamin 1,25-(OH)2D3 on airway remodeling. The four groups of Z1 (1,25-(OH)2D3+RNPEG-ABT-199), Z2 (RNPEG-ABT-199), Z3 (ABT-199), and Z4
(normal Control) were designed in this study. The prepared acid-responsive mitochondrial targeting nanomedicine (RNPEG-ABT-199) and non-responsive mitochondrial targeting nanomedicine (PEG-ABT-199) were applied to the treatment of asthma mouse models. The results showed the PU value of caspase-3
in Z4 was lower than Z1, Z2, and Z3 groups; and in Z3 was higher than Z1 and Z2 groups. IL-4, IL-5, and TNF-α levels in Z3 were obviously higher than Z1, Z2, and Z4 groups, while those in the Z1 were obviously lower than the Z2 and Z4 groups; the proliferation activity of airway
smooth muscle cells (ASMCs) of Z3 was obviously higher than the Z1, Z2, and Z4 groups, and that of the Z1 was obviously lower than the Z2 group. In short, RNPEG-ABT-199 has stronger lysosomal escape ability and mitochondrial targeting than PEG-ABT-199. RNPEG-ABT-199 can cause apoptosis of
inflammatory cells and decrease pro-inflammatory cytokines, which is better than PEG-ABT-199. Vitamin1,25-(OH)2D3 can obviously inhibit the proliferation activity of ASMCs cells, and be used in the treatment of asthma along with RNPEG-ABT-199.

Abstract
INTRODUCTION Previous research shows the associations between secondhand smoke exposure and health consequences among youth, but less is known about its effect on academic performance. This study examines a dose-response relationship between secondhand smoke exposure and subsequent academic performance among U.S. youth. METHODS Data were from a nationally representative sample of youth non-tobacco users (aged 12-16 years) in Wave 2 (2014-2015) who completed Wave 3 (2015-2016) of the Population Assessment of Tobacco and Health Study (n=9,020). Past-7-day number of hours exposed to secondhand smoke at Wave 2 and academic performance at Wave 3 (1=Mostly As to 9=Mostly Fs) were assessed. Weighted multivariable linear regression models were used to examine the association between hours of self-reported secondhand smoke exposure at Wave 2 and academic performance at Wave 3 (1=Mostly Fs, 9=Mostly As), adjusting for covariates including sociodemographics, prior academic performance, internalizing and externalizing problems, and substance use problems. Analyses were conducted in 2019. RESULTS More than 30% of U.S. youth non-tobacco users were exposed to secondhand smoke in the past 7 days. Compared with unexposed youth at Wave 2, those who were exposed for 1-9 hours had poorer academic performance at Wave 3 (adjusted regression coefficient= -0.11, 95% CI= -0.18, -0.04), and those who were exposed for ≥10 hours at Wave 2 had even poorer academic performance (adjusted regression coefficient = -0.31, 95% CI= -0.45, -0.18). CONCLUSIONS A dose-response relationship was observed between secondhand smoke exposure and academic performance among U.S. youth. Reducing youth secondhand smoke exposure may promote academic performance and subsequent educational attainment.

Abstract
More than 6.5 million children in the United States, approximately 13% of all students, miss 15 or more days of school each year. The rates of chronic absenteeism vary between states, communities, and schools, with significant disparities based on income, race, and ethnicity. Chronic school absenteeism, starting as early as preschool and kindergarten, puts students at risk for poor school performance and school dropout, which in turn, put them at risk for unhealthy behaviors as adolescents and young adults as well as poor long-term health outcomes. Pediatricians and their colleagues caring for children in the medical setting have opportunities at the individual patient and/or family, practice, and population levels to promote school attendance and reduce chronic absenteeism and resulting health disparities. Although this policy statement is primarily focused on absenteeism related to students' physical and mental health, pediatricians may play a role in addressing absenteeism attributable to a wide range of factors through individual interactions with patients and their parents and through community-, state-, and federal-level advocacy.

Abstract
OBJECTIVE To estimate asthma prevalence, severity, and associated factors in adolescents who live in a low relative humidity environment. METHODS In this cross-sectional study, adolescents aged 13-14 years from the city of Petrolina located in the Brazilian semiarid region answered the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire. The possible explanatory variables of the study were gender, family income, mother's education, smokers in the household, parental history of asthma, personal history of allergic rhinitis or atopic dermatitis, and physical activity level. Poisson regression analysis was used to assess the association between asthma and the explanatory variables. RESULTS A total of 1591 adolescents participated in the study, of whom 49.7% were male. The prevalence of active asthma, severe asthma, and physician-diagnosed asthma were 14.0%, 10.4%, and 17.8%, respectively. Adolescents with asthma missed more school days than their peers (33 vs. 22 days/year; p<0.03). Associated factors that remained significant after adjustment were history of asthma in parents (PR=2.65, p<0.001) and personal diagnosis of allergic rhinitis (PR=1.96, p<0.001) and/or atopic dermatitis (PR=2.18, p<0.001). CONCLUSION Asthma prevalence in this low-humidity environment was lower, but more severe than those reported in other Brazilian cities. The dry climate might hamper disease control and this may have contributed to the higher school absenteeism observed. The association of asthma with allergic rhinitis and atopic dermatitis as well as a history of asthma in parents suggests that atopy is an important risk factor for asthma in this population.

Abstract
INTRODUCTION Asthma is a leading cause of chronic disease-related school absenteeism. Few data exist on how information on absenteeism might be used to identify children for interventions to improve asthma control. This study investigated how asthma-related absenteeism was associated with asthma control, exacerbations, and associated modifiable risk factors using a sample of children from 35 states and the District of Columbia. METHODS The Behavioral Risk Factor Surveillance System Child Asthma Call-back Survey is a random-digit dial survey designed to assess the health and experiences of children aged 0-17 years with asthma. During 2014-2015, multivariate analyses were conducted using 2006-2010 data to compare children with and without asthma-related absenteeism with respect to clinical, environmental, and financial measures. These analyses controlled for sociodemographic and clinical characteristics. RESULTS Compared with children without asthma-related absenteeism, children who missed any school because of asthma were more likely to have not well controlled or very poorly controlled asthma (prevalence ratio=1.50; 95% CI=1.34, 1.69) and visit an emergency department or urgent care center for asthma (prevalence ratio=3.27; 95% CI=2.44, 4.38). Mold in the home and cost as a barrier to asthma-related health care were also significantly associated with asthma-related absenteeism. CONCLUSIONS Missing any school because of asthma is associated with suboptimal asthma control, urgent or emergent asthma-related healthcare utilization, mold in the home, and financial barriers to asthma-related health care. Further understanding of asthma-related absenteeism could establish how to most effectively use absenteeism information as a health status indicator.

Abstract
OBJECTIVE To assess limited English proficiency (LEP) asthma caregiver quality of life (QoL), skills retention and healthcare utilization after an asthma education fair (AEF). METHODS A language concordant AEF was conducted at a Latino community center. LEP caregivers of children 1-12 years old and an established asthma diagnosis participated in three skill stations: (a) medication recognition and administration, (b) peak flow use (if child ≥ 5 years) and (c) action plan dissemination. Spacers, peak flow meters and individualized action plans were distributed. A validated, pediatric asthma caregiver quality of life questionnaire (PACQLQ-Spanish version) was administered. Baseline data was compared to follow-up interview data at three and six months after the AEF. Mean PACQLQ scores were analyzed with Wilcoxon signed-rank test and nominal paired data with McNemar's test. RESULTS We analyzed data from 18 caregivers able to speak English well (22%), not well (28%) or not at all (50%). After three months, improved caregiver QoL was experienced (51 vs. 72, p<0.01). No differences were observed in medication recognition, spacer and peak flow use or peak flow interpretation. After six months, mean school days missed due to asthma decreased (4.1 vs. 0.4, p<0.01). Mean clinic visits, emergency department visits and hospitalizations remained unchanged. CONCLUSIONS Implementation of a community-based AEF with action plan administration can be beneficial for LEP caregivers and their children. QoL improvements to emotional wellbeing and activity limitations were observed, and lower rates of school absenteeism were reported. Caregiver ability to accurately identify medications was not enhanced.

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
BACKGROUND Schools are an ideal setting for implementation of asthma interventions for children; however, sustaining school-based programs can be challenging. This study illustrates policy and practice changes brought about through the Childhood Asthma Linkages in Missouri (CALM) program to sustain such programs. METHODS Researchers analyzed caregiver-reported quantitative data regarding asthma-related outcomes in preintervention and postintervention surveys and qualitative data regarding sustainability efforts in schools reported by CALM grantees. A grounded theory approach was used to identify key concepts and themes that emerged. RESULTS In 330 children, significant improvements were seen in asthma symptoms, rescue inhaler use, health care utilization, school absenteeism, and activity limitations. Overall, 27 school-based policy and practice changes supporting program sustainability were reported, with policy changes most often concerning the assessment and/or monitoring of children with asthma in the school setting, and practice changes most often regarding institution of regular asthma education programs for students and school personnel. CONCLUSIONS Sustaining school-based asthma programs is challenging, but can be realized through the participation of diverse partners in enacting policy and practice changes that support the institutionalization of programs into the day-to-day processes of the schools.

Abstract
BACKGROUND Studies show that adult dialysis patients with allograft failure have increased mortality and morbidity on dialysis compared to transplant naïve patients. We previously showed comparable mortality risk in pediatric dialysis patients after allograft failure compared to transplant naïve patients; the impact on morbidity is less clear. Specifically, the effect of allograft failure on school attendance in pediatric patients has not previously been studied. METHODS Using the North American Pediatric Renal Trials and Collaborative Studies database, we compared school attendance between transplant naïve and allograft failure patients from 1 January 1992 to 31 December 2007. School attendance was compared between the two groups at 6 and 12 months after dialysis initiation using a chi-square test. Factors which can potentially impact on school attendance data were evaluated using a multivariate logistic regression analysis. RESULTS There were 2783 patients who had a follow-up at least 6 months after dialysis initiation and were capable of attending school during the study period. Patients were categorized by transplant history: previous allograft failure (n=576) and transplant naïve (n=2207). At 6 months, full-time school attendance was 67.2% in the allograft failure group and 72.3% in the transplant naïve group (P=0.0164). At 12 months, attendance was 68.6% in the allograft failure group and 72.5% in the transplant naïve group (P=0.103). After covariate adjustment, transplant failure did not impact school attendance at either 6 or 12 months follow-up [hazard ratio (HR) 1.12, confidence interval (CI) 0.91-1.39; HR 0.99, CI 0.78-1.27, respectively]. CONCLUSIONS Children with failed allografts who return to dialysis have comparable school attendance compared to their transplant naïve dialysis counterparts. These results suggest that transplant failure is not an adverse prognostic factor for quality of life as measured by full-time school attendance.

Abstract
BACKGROUND The purpose of this analysis was to examine potential associations between absence, extended (repeated) absence, tardiness, and repeated tardiness from school and doctor-diagnosed asthma. METHODS A cross-sectional analysis was conducted using data collected in fall 2007 on 914 4th and 5th grade school children from seven randomly selected participating schools in DeKalb County, GA. ANOVA was used to compare attendance metrics for race, gender, and asthma status groups. Nonparametric Kruskal-Wallis statistical tests were also done because distributions of attendance metrics were skewed. We tallied daily absence data during the study period and examined absence by day of week. We also compared the variation of the weekly rate of absence and tardiness for students with asthma versus students without asthma over the study period. RESULTS The mean days of absence in 86 students with asthma was 2.73 days compared with 1.89 days for 828 children without asthma (p = .004). There was no significant difference in mean days of tardiness by asthma status. The difference in the number of instances of 2+ consecutive days of absence (extended absence) by asthma status was not significant. Students with asthma were more likely to be absent on Mondays (p = .005), Tuesdays (p = .001), and Fridays (p = .02) than students without asthma. The weekly rate of tardiness for students with asthma trended with the general student study population over the study period, whereas the weekly rate of absence did not. CONCLUSIONS Asthma was associated with increased 1-day absences but not longer absences or tardiness.
