Abstract
OBJECTIVE We aim to assess the risk factors of uncontrolled asthma in children and adolescents. METHODS A systemic search was conducted from electronic databases (PubMed/Medline, Cochrane Library, and Google Scholar) from inception to July 17, 2023. All statistical analyses were conducted in Review Manager 5.4.1. Studies meeting inclusion criteria were selected. A random-effects model was used when heterogeneity was seen to pool the studies, and the result was reported in the odds ratio and the corresponding 95% confidence interval. We also used a narrative approach where it was not feasible to quantitatively assess the outcome. RESULTS Ten observational studies were used to conduct this systematic review and meta-analysis. A quantitative analysis of five factors was done. Pooled analysis showed a statistically significant risk of uncontrolled asthma in association with past hypersensitivity reactions (standardized mean difference [SMD] = 1.51 (1.16, 1.98); p = .002; I2 = 84%) and incomplete controller adherence (SMD = 3.15 (1.83, 5.41); p < .0001; I2 = 94%). While non-significant relation was seen in parental asthma (SMD = 1.23 (0.98, 1.55); p = .07; I2 = 15%), oral corticosteroid use (SMD = 0.99 (0.72, 1.36); p = .96; I2 = 81%) and education of caregivers (SMD = 0.99 (0.72, 1.36); p = .96; I2 = 81%). Some other factors were also discussed qualitatively. CONCLUSION Our study shows that some significant risk factors might cause uncontrolled asthma in children and adolescents like past hypersensitivity reactions and incomplete controller adherence.

Abstract
The Saudi Initiative for Asthma 2024 (SINA-2024) is the sixth version of asthma guidelines for the diagnosis and management of asthma for adults and children that was developed by the SINA group, a subsidiary of the Saudi Thoracic Society. The main objective of the SINA is to have guidelines that are up-to-date, simple to understand, and easy to use by healthcare workers dealing with asthma patients. To facilitate achieving the goals of asthma management, the SINA Panel approach is mainly based on the assessment of symptom control and risk for both adults and children. The approach to asthma management is aligned for age groups: adults, adolescents, children aged 5-12 years, and children aged <5 years. SINA guidelines have focused more on personalized approaches reflecting a better understanding of disease heterogeneity with the integration of recommendations related to biologic agents, evidence-based updates on treatment, and the role of immunotherapy in management. The medication appendix has also been updated with the addition of recent evidence, new indications for existing medication, and new medications. The guidelines are constructed based on the available evidence, local literature, and the current situation at national and regional levels. There is also an emphasis on patient-doctor partnership in the management that also includes a self-management plan.

Abstract
Objective To estimate the frequency of uncontrolled asthma among asthmatic children from Jeddah and to analyze its association with parental asthma knowledge and other socioeconomic and environmental factors. Method A cross-sectional study was conducted at the Pediatrics Departments of King Abdulaziz University Hospital (KAUH) in Jeddah, Saudi Arabia, from July to December 2018. It involved the caregivers of 150 children with asthma, who were following at KAUH. A structured questionnaire was administered by a phone interview to collect the following: socioeconomic and environmental factors of asthma, answers to the Arabic version of the Asthma Control TestTM (ACT), and answers to the Arabic version of the caregiver Asthma Knowledge questionnaire (AKq). Result The frequency of uncontrolled asthma was 32.7% (95%CI: 25.2 - 40.8). Parents had myths about asthma such as "children with asthma should use asthma control medications (inhaled corticosteroids) only when they have symptoms" and "it's not good for children to use the inhaler for too long". Besides, we observed mixed results regarding parents' knowledge about the disease, with correct answers ranging from 56.0% to 88.7% depending on the item. Exposure to bakhoor (aromatic woodchips) at home (OR = 0.41, p=0.044), two or more ICU admissions during the past 12 months (OR = 3.30, p=0.030), and using a rescue inhaler even if there's no cough or wheeze when the child gets the flu (OR = 0.22, p=0.001) were the three independent factors of uncontrolled asthma among children. Conclusion Uncontrolled asthma concerns one-third of the asthmatic children following at our centre, representing a less concerning figure compared to the national data. The contribution of parents' knowledge to asthma control did not show significant results, although uncontrolled asthma may represent an opportunity to increase parents' knowledge and awareness. We emphasize the significance of exposure to bakhoor, the use of oral steroids, and the number of ICU admission as strong indicators for uncontrolled asthma in children. An adaptive national strategy should be designed to enable effective and personalized interventions, resources, and objectives for maximized benefits.

Abstract
OBJECTIVE The aim of this study was to determine the effect of an education program, the Health Promotion Program for Children with Asthma (HPPCA), on disease control and quality of life in children aged between 7 and 11 and diagnosed with asthma. The program was developed using cartoons and color-in materials and was based on the health promotion model developed by Nola J. Pender and brain-based learning theories. MATERIALS AND METHODS The sample of the study consisted of 74 children between the ages of 7 and 11 who presented to the respiratory diseases' unit of a university hospital in Istanbul. All participants were given basic asthma education by their physicians, and were then randomly assigned to a group that received the HPPCA program or a control group that received no further education. After the HPPCA education was applied to the experimental group alone, both groups were administered two post-tests as a follow-up and retest at the end of the first and fourth month after the intervention. The standardized Sociodemographic Question Form, the Childhood Asthma Control Test (C-ACT) and the Pediatric Asthma Quality of Life Questionnaire (PAQLQ) were used for the follow-up. RESULTS The asthma control and quality of life scores of the children included in the experimental group were found to be significantly higher compared to the control group at the first- and fourth-month follow-ups (p<.001). The rate of school absenteeism decreased significantly in children who received HPPCA education at the first follow-up compared to the children who did not receive the education (p<.05). PRACTICE IMPLICATIONS The present study found that the HPPCA education, whose design was based on the health promotion model, and which was supported by cartoons in order to attract the attention of the children, was effective. The HPPCA was proven to create a sense of control over asthma and to improve the quality of life in the children. It is recommended that there be an asthma nurse in pediatric allergy and immunology outpatient clinics who can specifically provide an HPPCA. Further studies should be conducted to demonstrate the effectiveness of this program, which was examined in the present study for the first time with a randomized controlled method.HighlightsAsthma control is extremely important for the quality of life in children with asthma.Asthma education provided to school-age children yields the best results when new teaching techniques and multimedia content are used.Asthma education for children must be based on a good theoretical methodology.Children can best manage asthma when they learn about it directly.Asthma education conducted according to the guidelines is of great importance during the COVID-19 pandemic.

Abstract
Background and objective Improving adherence to asthma medications may prevent asthma exacerbation, which is associated with a decline in lung function. The purpose of this study was to assess the adherence to asthma controller therapy and the factors that might influence the level of adherence among asthmatic children. Materials and methods We conducted a prospective observational study at the King Khalid Hospital in Majmaah, Saudi Arabia between January and April 2020; the study was conducted among children aged 1-14 years with a diagnosis of asthma. The data collected when available included age and gender by using a pre-tested questionnaire that contained four validated items, and the respondents were the parents of the affected children. Due to the coronavirus disease 2019 (COVID-19) pandemic, the data collection was performed via phone calls to ensure safety. Informed consent was obtained from the parents. Results We analyzed 152 asthmatic children to evaluate their adherence to asthma controller therapy. The majority of the children were males (60%). Asthma was most prevalent in the age group of 6-10 years (40.1%), followed by the age group of two to five years (32.9%). We found that the majority of the patients had poor adherence to asthma medication (83.6%) while the remaining had good adherence (16.4%). The total mean score for adherence to medication therapy was 5.16 (SD: 2.3). Conclusions The present study showed that the overall adherence level to the asthma controller therapy was poor among children. Larger, nationwide studies are needed to assess the adherence to asthma medications and implement interventions that can improve the same.

Abstract
OBJECTIVE To evaluate the impact of pediatric asthma on patients of a specialized outpatient clinic in Southern Brazil. METHODS The study included children aged 8 to 17 years old with asthma diagnosis (mild, moderate and severe) under treatment at the asthma clinic of Hospital São Lucas da Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS), Brazil. Measurements of spirometry, quality of life, disease control and atopy tests were applied. RESULTS A total of 66 children were included in the study and divided into groups, according to the severity of the disease: mild, moderate or severe asthma. The results showed similarities in both the treatment and the impact of asthma between groups, except for adherence to treatment: the group with mild asthma showed least adherence to treatment, and the group with severe asthma, greater adherence (p=0.011). As to school absenteeism, the group with severe asthma showed higher frequency (p=0.012), with over 10 days per year (p=0.043). Spirometry showed lower volume/capacity for the group with moderate asthma, followed by the groups with severe and mild asthma. All groups had a high prevalence of allergic asthma, with mites as the main allergens. For quality of life (QOL), and health-related quality of life (HRQOL) levels, there were no differences between groups. In addition, the values were close to the acceptable levels for the total score and for each one of the six domains. The same occurred for the HRQOL-asthma module. CONCLUSIONS QOL and HRQOL present acceptable levels regardless of the severity of the disease.

Abstract
Introduction Pharmacists can have a valuable role in educating patients on correct inhaler technique leading to improved asthma management. Rural areas can benefit from the role of the pharmacist considering the barriers found in attending primary health-care facilities. Objectives This study aimed to assess the impact of inhaler technique education delivered by pharmacists on patients’ inhaler technique, Asthma Control Test (ACT) score, forced expiratory volume in the first 1 second (FEV1%), and reliever use (puffs/day). Methods A pre–post interventional study was conducted over 6 months from February 2017 to July 2017 in rural areas in Jordan. Asthma patients visiting respiratory clinics and using metered dose inhaler (MDI) or turbuhaler (TH) controlled medication were randomly recruited. Inhaler technique was assessed via published checklists. The ACT, FEV1%, and reliever use (puffs/day) were assessed. Patients were educated on inhaler technique via demonstration with return demonstration education. All assessments were repeated 3 months post education. Results A total of 103 (TH, n=44; MDI, n=59) patients were recruited (mean age=46.5±13.5), 74% females. Patients reported an overuse of their reliever (5.1±4.2 puffs/day). Only 2 patients (1.9%) had well-controlled asthma, while the rest had either moderately (19.4%) or poorly (78.6%) controlled asthma. Patients using the MDI achieved 3.03±4.30 ACT score improvement (p<0.001), which is a clinically significant improvement in control. Patients using the TH achieved a statistically significant improvement of 2.07±4.72 (p=0.031). FEV1% improved significantly for MDI users (p=0.005) but not for TH users (p=0.097). Reliever use decreased significantly for MDI and TH users. Conclusion Asthmatic patients living in rural areas in Jordan reported poor inhaler technique, ACT scores, and FEV1% scores and high use of reliever medications. Pharmacist-led educational intervention resulted in improved inhaler technique scores, ACT scores, and FEV1% scores and lowered reliever use over time.

Abstract
OBJECTIVE Interleukin 13 (IL-13) plays a critical pro-inflammatory role in asthma. Several single nucleotide polymorphisms (SNPs) are associated with asthma susceptibility in specific populations; however, further replicative studies in other ethnic groups are mandatory. METHODS The association between IL-13 SNPs rs762534, rs20541, rs1295686, and rs1800925 (risk alleles A, A, T, and A, respectively) and asthma predisposition in a Saudi Arabian cohort was examined via a case-control cross-sectional study. RESULTS The frequencies of alleles between asthmatics and control populations were significantly different for rs20541 and rs1295686 SNPs (p < 0.001), whereas the frequencies of genotypes between asthmatics and controls were significantly different only for rs20541. The association of the risk (minor) alleles with asthma was examined using the dominant genetic model. Individuals with at least one copy of the risk alleles A (for rs20541) and T (for rs1295686) had significantly greater odds of being asthmatic (OR = 2.13, 95% CI = 1.39-3.26, p < 0.0001; OR = 1.69, 95% CI = 1.12-2.54, p = 0.008) relative to their most common homozygous genotypes. On the other hand, the minor A alleles for rs762534 and rs1800925 were not significantly associated with asthma risk. Regarding haplotype association analysis, individuals with at least one copy of the minor "risk" allele for both rs20541 and rs1295686 (CATG and CATA, respectively) had greater odds of being asthmatic relative to CGCG haplotype; however, this trend was not statistically significant (p > 0.3). CONCLUSIONS IL-13 minor T and A alleles for rs1295686 and rs20541, respectively, were associated with significantly higher risk of asthma in the Saudi Arabian population.
