Abstract
Numerous studies have elucidated the intricate relationship between bronchial asthma and small cell lung cancer (SCLC), as well as the role lipid metabolism genes play in transitioning from bronchial asthma to SCLC. Despite this, the predictive power of single gene biomarkers remains insufficient and necessitates the development of more accurate prognostic models. In our study, we downloaded and preprocessed scRNA-seq of SCLC from the GEO database GSE164404 and severe asthma scRNA-seq from GSE145013 using the Seurat package. Using the MSigDB database and geneCard database, we selected lipid metabolism-related genes and performed scRNA-seq data analysis from the gene expression GEO database, aiming to uncover potential links between immune signaling pathways in bronchial asthma and SCLC. Our investigations yielded differentially expressed genes based on the scRNA-seq dataset related to lipid metabolism. We executed differential gene analysis, gene ontology, and Kyoto Encyclopedia of Genes and Genomes analyses. In-depth GSEA pathway activation analysis, crucial target gene predictions via protein-protein interactions, and key cluster gene evaluations for differential and diagnostic ROC values correlation analysis confirmed that key cluster genes are significant predictors for the progression of bronchial asthma to SCLC. To validate our findings, we performed wet laboratory experiments using real-time quantitative PCR to assess the expression of these relevant genes in SCLC cell lines. In conclusion, this research proposes a novel lipid metabolism-related gene marker that can offer comprehensive insights into the pathogenesis of bronchial asthma leading to SCLC. Although this study does not directly focus on senescence-associated molecular alterations, our findings in the lipid metabolism genes associated with inflammation and cancer progression offer valuable insights for further research targeting senescence-related changes in treating inflammatory diseases.

Abstract
The goal of this meta-analysis was to study nasal nitric oxide (nNO) measurements in allergic rhinitis (AR) and non-allergic rhinitis (non-AR). The protocol was registered with PROSPERO (no: CRD4202124828). Electronic databases from PubMed, Google Scholar, Scopus, Web of Science, and Cochrane were all thoroughly searched and studies were chosen based on the qualifying requirements. The quality of the studies was evaluated by Joanna Briggs Institute evaluation tools, and publication bias using funnel plots. The meta-analysis included 18 studies, whereas the systematic review included 20 studies, totaling 3097 participants (1581 AR, 458 non-AR, and 1058 healthy/control). Patients with AR had significantly greater nNO levels than the control group, although this did not change significantly before or after treatment. AR patients had significantly greater nNO levels than non-AR patients, but there was no significant difference between non-AR patients and healthy controls. Nineteen of the studies were of high quality and the remaining one was of moderate quality. nNO measurement has a promising role in the management of AR and non-AR patients, but more investigations are needed to document clinical benefits.

Abstract
Objective To explore the value of a new model based on CT radiomics in predicting the staging of patients with bronchial asthma (BA). Methods Patients with BA from 2018 to 2021 were retrospectively analyzed and underwent plain chest CT before treatment. According to the guidelines for the prevention and treatment of BA (2016 edition), they were divided into two groups: acute attack and non-acute attack. The images were processed as follows: using Lung Kit software for image standardization and segmentation, using AK software for image feature extraction, and using R language for data analysis and model construction (training set: test set = 7: 3). The efficacy and clinical effects of the constructed model were evaluated with ROC curve, sensitivity, specificity, calibration curve and decision curve. Results A total of 112 patients with BA were enrolled, including 80 patients with acute attack (range: 2-86 years old, mean: 53.89±17.306 years old, males of 33) and 32 patients with non-acute attack (range: 4-79 years old, mean: 57.38±19.223 years old, males of 18). A total of 10 imaging features are finally retained and used to construct model using multi-factor logical regression method. In the training group, the AUC, sensitivity and specificity of the model was 0.881 (95% CI:0.808-0.955), 0.804 and 0.818, separately; while in the test group, it was 0.792 (95% CI:0.608-0.976), 0.792 and 0.80, respectively. Conclusion The model constructed based on radiomics has a good effect on predicting the staging of patients with BA, which provides a new method for clinical diagnosis of staging in BA patients.

Abstract
Summary Background. Chronic rhinosinusitis (CRS) is an inflammatory disease that affects the nasal mucosa and the paranasal sinuses. CRS can be associated by nasal polyposis (CRSwNP phenotype) in up to 30% of patients and it is frequently associated with bronchial asthma. CRSwNP shows predominantly an underlying activation of type 2 inflammatory pathways with the involvement of eosinophils, IgE, interleukin (IL)-4, IL-5 and IL-13. Biological drugs that target these inflammatory cytokines are currently a therapeutic option recognized by guidelines for the treatment of uncontrolled form of the disease. Methods. As part of the activity of the "ARIA-Italy" working group, a panel of 255 Italian Ear, Nose and Throat (ENT) specialists, pneumologists and immuno-allergologists actively participated in this national survey and answered a series of questions geared toward understanding the main criteria for patient characterization and therapeutic decision, highlighting multidisciplinarity, and the implementation of the management of CRSwNP patients, as a part of the precision medicine concept and the appropriate use of the biologicals. Results. Two hundred and fifty-five experts and specialists participated in the survey. Conclusions. The results of this survey obtained from an extensive number of active specialists throughout Italy allow some important concluding remarks to be drawn. The main points of agreement were that multidisciplinary care teams provide many benefits but that, once the team is established, meetings and communication between members must be coordinated. Finally, the dissemination of national disease registries and the continuous updating of guidelines and position papers related to CRSwNP and comorbidities should be encouraged.

Abstract
Aim: We compared the effectiveness of rush subcutaneous immunotherapy (SCIT) and sublingual immunotherapy (SLIT) using standardized house dust mite (HDM) extract for pediatric bronchial asthma (BA). Methods: We followed the pediatric BA treatment score during 3 years of treatment. We assessed the median time to no longer requiring long-term control pharmacotherapy (LTCP) for BA (LTCP-free). We compared the outcomes after adjustment for confounding factors and propensity score matching. Results: Patients in the HDM SCIT group achieved the LTCP-free status significantly earlier than those in the HDM SLIT group after adjustment for confounding factors and propensity score matching. Conclusion: Patients treated for pediatric BA with rush HDM SCIT had earlier onset of therapeutic effects than those with HDM SLIT.

Abstract
Bronchial asthma (BA) is a chronic respiratory disease closely related to immune system dysregulation. Traditional Chinese medicine has long adopted the strategy of Sanao decoction in the treatment of bronchial asthma. However, due to the multi-target and multi-pathway characteristics of Chinese herbal medicine, we are still unclear about the specific mechanism of Sanao decoction in treating bronchial asthma. To investigate the mechanism of action of Sanao decoction in the treatment of BA using a network pharmacology approach and preliminary validation by molecular docking technology. Traditional Chinese medicine systems pharmacology database and analysis platform and UniProt databases were used to search the active ingredients and targets of Sanao decoction, and BA-related targets were screened according to GeneCards and online Mendelian inheritance in man database databases. The intersection targets were imported into the STRING database to construct a protein-protein interaction network, and Cytoscape 3.9.1 software was used to screen out hub genes. This study also constructed a "drug-ingredient-target" visual network diagram. Gene Ontology and Kyoto Encyclopedia of Genomes enrichment analysis was performed on targets in the protein-protein interaction network using the ClusterProfiler package in R, with a P value < .05. Autodock software was used for molecular docking to complete the preliminary verification of core components and targets. A total of 73 active compounds and 308 targets of Sanao decoction, including 1640 BA-related disease targets, were retrieved from mainstream databases. Gene Ontology analysis and Kyoto encyclopedia of genes and genomes enrichment analysis suggested that Sanao decoction plays a role in the treatment of BA through signaling pathways such as PI3K-Akt, MAPK, and IL-17 signaling pathway. The 9 core goals represent the main elements related to Sanao decoction in the treatment of BA. Subsequently, the molecular docking results showed that most of the active compounds of Sanao decoction have strong binding efficiency with the hub gene. Sanao decoction has a key impact on BA through multiple channels. In summary, this intricate network reflects the potential of Sanao decoction in treating BA, a multifactorial disease. In addition, this study laid the foundation for further in vivo and in vitro experimental research and expanded the clinical application of Sanao decoction.

Abstract
Allergic bronchopulmonary aspergillosis (ABPA) often necessitates treatment with systemic steroids and antifungals, which are associated with relapses and side effects. We report an 82-year-old woman with eosinophilic asthma, experiencing sputum production and dyspnea, who was diagnosed with ABPA based on her chest CT, pulmonary function tests, and elevated blood eosinophils and immunoglobulin E. Due to the presence of osteoporosis and diabetes, standard steroid therapy was considered a high risk. Instead, we administered dupilumab, an interleukin 4 receptor alpha (IL4-Rα) antibody targeting Th2 cytokine signaling. Remarkable improvements were observed within two weeks, including reduced sputum and dyspnea. After 12 weeks, significant enhancements in asthma control and lung function, along with decreased fractional exhaled nitric oxide (FeNO) levels were noted, with chest CT showing resolution of most of the mucus plugs. This case demonstrates dupilumab's potential as a viable ABPA treatment alternative, particularly for patients who are unsuitable for systemic steroids. More research on the long-term effectiveness and safety of such biologics is needed.

Abstract
Bronchial asthma (BA) exhibits varying prevalence across global populations, prompting a comprehensive investigation into genetic and environmental determinants. Vitamin D is a potent immunomodulator capable of suppressing inflammatory signals in several cell types involved in the asthmatic response; it exerts effects on the immune system by binding to the nuclear vitamin D receptor (VDR). VDR gene genetic variations are affecting serum vitamin D levels with a possible role in the BA risk. The current study aimed to examine the complex interaction of various factors (genetic background, serum vitamin D levels, and geographic location) to identify differences in the influence of these factors on the susceptibility to asthma between populations at different latitudes. Focusing on Eastern European cohorts from Latvia and Lithuania and comparing them with published data on East Asian populations, we explore the impact of VDR gene polymorphisms on BA susceptibility. Genotyping four key VDR SNPs and assessing their association with 25-hydroxyvitamin D levels, our study unveils significant associations of the studied loci with the risk of asthma-both risk-reducing and increasing effects, differently distributed between Baltic and East Asian populations. The functional effects of in silico VDR gene genetic variations are also identified and discussed.

Abstract
OBJECTIVES Stress is an aversive stimulus which disrupts the biological milieu of the organism and a variety of emotional and environmental stressors are known to influence allergic and immunological disorders like bronchial asthma but the pharmacological basis of such interactions is not clearly defined. Withania somnifera (ashwagandha) is a potent anti-stress agent used widely in Indian traditional medicine and the present experimental study evaluated the effects of W. somnifera extract (WSE) on chronic stress-induced neurobehavioral and immunological responses in an experimental model of allergic asthma in rats. METHODS Wistar rats (200-250 g) were immunized and challenged with ovalbumin (OVA) and exposed to restraint stress (RS) and WSE treatments for 15 days. Following this, anxiety behavior was assessed by the elevated plus maze (EPM) test, and blood and BAL fluid samples were collected for measuring of inflammatory/immune markers by ELISA and biochemical assay. The data of the various treatment groups were analyzed by ANOVA and Tukey's test. RESULTS Restraint stress (RS) induced anxiogenic behavior in the (EPM) test in OVA immunized rats, and this was attenuated by WSE (200 and 400 mg/kg), in a dose related manner. Examination of blood and BAL fluid in these RS exposed rats also resulted in elevations in IgE, TNF-α and IL-4 levels, which were also attenuated by WSE pretreatments. Further, WSE pretreatment neutralized the such RS induced changes in oxidative stress markers viz. elevated MDA and reduced GSH levels. CONCLUSIONS The data pharmacologically validates role of stress in asthma and suggests that adaptogens like WSE could be a potential complementary agent for reducing anxiety as well as airway inflammation by a multi-targeted and holistic approach. The study also highlights the significance of integration of traditional and modern medical concepts in such chronic disorders.

Abstract
AIM This study aimed to investigate the impact of bronchial asthma-related factors on the emotional well-being of adolescents with bronchial asthma and their primary caregivers. BACKGROUND Bronchial asthma is a common chronic disease in childhood and adolescence that can have a psychological impact on both patients and their primary caregivers. METHODS The study used a cross-sectional design and included 150 patient-caregiver dyads diagnosed with bronchial asthma, aged between 12 and 16 years and collected between 2018 and 2020. It assessed the emotional adjustment of both patients and caregivers and recorded variables related to the disease. Qualitative and quantitative analyses were conducted to perform statistical analyses. RESULTS Caregivers had higher anxiety and depression scores than patients. Good adherence to treatment was necessary for the emotional adjustment of the dyad. Controlled asthma, good adherence to treatment and a reduction in medical treatment were the primary predictors of emotional adjustment. CONCLUSIONS The study highlights the importance of assessing anxiety and depression levels in both patients and caregivers because the presence of these symptoms can lead to the misuse of medication, inadequate inhalation techniques, the omission of medication and reduced confidence in controlling asthma symptoms.

Abstract
BACKGROUND Acute asthma exacerbation in children is often caused by respiratory infections. In this study, a coordinated national surveillance system for acute asthma hospitalizations and causative respiratory infections was established. We herein report recent trends in pediatric acute asthma hospitalizations since the COVID-19 pandemic in Japan. METHODS Thirty-three sentinel hospitals in Japan registered all of their hospitalized pediatric asthma patients and their causal pathogens. The changes in acute asthma hospitalization in children before and after the onset of the COVID-19 pandemic and whether or not COVID-19 caused acute asthma exacerbation were investigated. RESULTS From fiscal years 2010-2019, the median number of acute asthma hospitalizations per year was 3524 (2462-4570), but in fiscal years 2020, 2021, and 2022, the numbers were 820, 1,001, and 1,026, respectively (the fiscal year in Japan is April to March). This decrease was observed in all age groups with the exception of the 3- to 6-year group. SARS-CoV-2 was evaluated in 2094 patients from fiscal years 2020-2022, but the first positive case was not detected until February 2022. Since then, only 36 of them have been identified with SARS-CoV-2, none of which required mechanical ventilation. Influenza, RS virus, and human metapneumovirus infections also decreased in FY 2020. In contrast, 24% of patients had not been receiving long-term control medications before admission despite the severity of bronchial asthma. CONCLUSION SARS-CoV-2 was hardly detected in children with acute asthma hospitalization during the COVID-19 pandemic. This result indicated that SARS-CoV-2 did not induce acute asthma exacerbation in children. Rather, infection control measures implemented against the pandemic may have consequently reduced other respiratory virus infections and thus acute asthma hospitalizations during this period. However, the fact that many hospitalized patients have not been receiving appropriate long-term control medications is a major problem that should be addressed.

Abstract
Background Bronchial asthma (BA) is a chronic inflammatory airway disease. Previous research has shown that Yanghe Pingchuan granules (YPG), among the granules formulated by the First Affiliated Hospital of the Anhui University of Chinese Medicine, exerts a precise therapeutic effect on BA. We previously showed that YPG improves airway inflammation in BA rats. Other studies have shown that the inhibitor of kappa-B kinase (IKK)/inhibitor of NF-κB (IκB)/nuclear factor kappa-B (NF-κB) signalling pathway plays a key role in inflammation mediation. Therefore, this study explored whether YPG could intervene in BA through the IKK/IκB/NF-κB signalling pathway. Methods Ovalbumin-induced method was used to established BA rat model. After successful modelling, the authors used YPG to intervene the rats in BA rats. Hematoxylin-eosin (HE) staining was used to detect the bronchial pathological changes in BA rats, enzyme-linked immunosorbent assay (ELISA) was used to detect the changes of inflammatory factors (IL-1β and IL-6) and oxidative stress indexes malondialdehyde (MDA), superoxide dismutase (SOD) and nitrogen monoxide (NO), Quantitative real-time polymerase chain reactionCR and western blot were used to detect the expression of IKK/IκB/NF-κB signalling pathway. Results In BA model rats, YPG significantly improved the inflammatory response in bronchial tissues, reduced inflammatory factors IL-1β and IL-6, alleviated oxidative stress, reduced MDA and NO, and increased SOD. Quantitative real-time polymerase chain reaction and western blot results showed that YPG could block the IKK/IκB/NF-κB signalling pathway. Conclusion These findings showed that YPG had a definite therapeutic effect on BA, which may be related to blocking the IKK/IκB/NF-κB signalling pathway and improving inflammation and oxidative stress.

Abstract
Bronchial asthma is an extremely heterogenous chronic respiratory disorder with several distinct endotypes and phenotypes. These subtypes differ not only in the pathophysiological changes and/or clinical features but also in their response to the treatment. Therefore, precise diagnostics represent a fundamental condition for effective therapy. In the diagnostic process, metabolomic approaches have been increasingly used, providing detailed information on the metabolic alterations associated with human asthma. Further information is brought by metabolomic analysis of samples obtained from animal models. This article summarizes the current knowledge on metabolomic changes in human and animal studies of asthma and reveals that alterations in lipid metabolism, amino acid metabolism, purine metabolism, glycolysis and the tricarboxylic acid cycle found in the animal studies resemble, to a large extent, the changes found in human patients with asthma. The findings indicate that, despite the limitations of animal modeling in asthma, pre-clinical testing and metabolomic analysis of animal samples may, together with metabolomic analysis of human samples, contribute to a novel way of personalized treatment of asthma patients.

Abstract
OBJECTIVE summarizing the results of many years of research by the authors on the influence of gene polymorphisms encoding xenobiotic biotransformation enzymes (GSTТ1, GSTM1, GSTР1), antioxidant protection (С^262Т of the catalase gene), endothelial nitric oxide synthase (4a/4b VNTR polymorphism of the eNOS gene), and some environmental factors on the occurrence of broncho-obstructive disorders and the development of bronchial asthma in children, residents of radioactively contaminated areas. MATERIALS AND METHODS The examined school-aged children were residents of radioactively RCA who had no clinical signs of respiratory pathology. Deletion polymorphism of catalase gene (CAT C^262T), polymorphism of glutathione-S-transferase gene (GSTТ1, GSTM1, GSTР1) and the polymorphism in the 4th intron (4a/4b) of the eNOS gene were studied in the molecular genetics laboratory of the State Institution «Reference Center for Molecular Diagnostics of Public Health Ministry of Ukraine». Molecular genetic studies were performed by polymerase chain reaction. The study of the ventilation lung capacity was carried out by the method of computer spirometry based on the data of the «flow-volume» loop analysis. A pharmacological inhalation test with a bronchodilator drug which affects the β2-adrenergic receptors of the lungs was used to detect early changes in the ventilatory lung capacity - bronchial hyperreactivity. RESULTS AND CONCLUSIONS One of the leading mechanisms, due to which the implementation of hereditary predisposition to bronchial asthma in children living in radioactively contaminated areas is the polymorphism of certain genes of glutathione-S-transferase, catalase, endothelial nitric oxide synthase. With such polymorphic variants of the GST genes, isoforms of enzymes with reduced activity are produced, which limits their ability to effectively neutralize free radicals, which are formed in excess when free radical oxidation processes are activated due to the constant intake of radionuclides with a long half-life into the body of children. Unfavorable factors that increase the risk of developing broncho-obstructive disorders and the likelihood of their implementation in the form of bronchial asthma in children, residents of radioactively contaminated areas, have been identified. It has been established that among them the leading role is played by hereditary predisposition to this disease. On the part of the child, such negative factors were unfavorable conditions of intrauterine development, the presence of signs of exudative-catarrhal diathesis, manifestations of allergies and frequent respiratory diseases from the first months of life.

Abstract
OBJECTIVE To analyze the effects of different types of inhalant allergens on the lung functions of adult patients with bronchial asthma. METHODS This cross-sectional study included a total of 47 adults diagnosed with bronchial asthma at the Respiratory Outpatient Department of Tianjin First Central Hospital. Patients were divided into non-sensitized and sensitized groups based on the number of positive allergens detected and classified into four groups (the dust mite mixed group, animal dander mixed group, pollen-mixed group, and mold mixed group) based on the type of positive allergen detected. They were tested for the serum concentration of allergen-specific immunoglobulin E (sIgE) using a fluorescence immunoassay analyzer, and lung function was assessed using a pulmonary function testing machine. One-way analysis of variance was used to compare normally distributed data, while the rank sum test was utilized for non-normally distributed data. RESULTS There was no statistically significant difference in lung function indicators between these two groups (p > .05). There were statistically significant differences in forced expiratory volume in one second as a percentage of the predicted value (FEV1 %pred) (p = .028), FEV1 /forced vital capacity as a percentage of the predicted value; (FVC%pred) (p = .016), peak expiratory flow as a percentage of the predicted value (PEF%pred) (p = .001), forced expiratory flow at 50% of the predicted value of forced vital capacity (FEF50%pred) (p = .003), forced expiratory flow at 75% of the predicted value of forced vital capacity (FEF75%pred) (p = .023), and maximal midexpiratory flow (MM)EF75/25%pred (p = .002) among the four groups. The pollen-mixed group had higher PEF%pred (pollen vs. animal dander, p = .067; pollen vs. dust-mites, p = .008; pollen vs. molds, p = .001) and MMEF75/25%pred (pollen vs. animal dander, p = .048; pollen vs. dust-mites, p = .003; pollen vs. molds, p = .001) than the other three groups. The pollen-mixed group had higher FEF50%pred than the dust-mites mixed group (p = .008) and molds-mixed group (p = .001). The pollen-mixed group had higher FEF75%pred (p = .005), FEV1 %pred (p = .001), and FEV1 /FVC%pred (p = .001) than the molds-mixed group. CONCLUSION Different inhalant allergens had different effects on lung functions in adults with asthma.

Abstract
BACKGROUND This study aims to systematically assess the possible link between bronchial asthma usage and attention-deficit hyperactivity disorder (ADHD) in children. METHODS PubMed, Web of Science, ScienceDirect, CNKI, Wanfang, and the China Biological Medicine Database (CBM) were searched for relevant articles published from database inception until September 28, 2023. The statistical analyses were conducted using Stata 15.1 software, followed by a quantitative meta-analysis to synthesize the results of the odds ratios (ORs) and their corresponding 95% confidence intervals (CIs). RESULTS A total of 10 articles involving 729,375 participants were included in the meta-analysis. The overall analysis revealed a statistically significant association between ADHD and an increased likelihood of having bronchial asthma, as indicated by a pooled odds ratio (OR) of 1.46 and a 95% confidence interval (CI) ranging from 1.41 to 1.51, p < 0.001, I2 = 58%. Potential associated factors linking bronchial asthma and ADHD in children include demographic characteristics, healthcare access, socioeconomic factors, comorbidities, genetic susceptibility, immune dysregulation, chronic conditions, growth and development factors, and parental/environmental influences. CONCLUSION This systematic review and meta-analysis presents convincing evidence for a notable link between bronchial asthma and ADHD in children. The results indicate an increased likelihood of bronchial asthma among children with ADHD compared to those without the condition. Additionally, various potential factors can underlie the association between bronchial asthma and ADHD in children, necessitating further research to fully comprehend their complex relationship. These findings have implications for clinical practice, highlighting the need for an integrated approach in managing asthma and ADHD.

Abstract
Eosinophilic airway inflammation, complicated by bronchial asthma and eosinophilic chronic rhinosinusitis (ECRS), is difficult to treat. The disease may become refractory when eosinophilic mucin associated with eosinophil peroxidase (EPX) and autoantibodies fills in the paranasal sinus and small airway. This study investigated the functional role of an anti-EPX antibody in eosinophilic mucin of ECRS in eosinophilic airway inflammation. Eosinophilic mucin was obtained from patients with ECRS. The effects of the anti-EPX antibody on dsDNA release from eosinophils and eosinophilic mucin decomposition were evaluated. Immunofluorescence or enzyme-linked immunosorbent assays were performed to detect the anti-EPX antibody and its supernatant and serum levels in eosinophilic mucin, respectively. The serum levels of the anti-EPX antibody were positively correlated with sinus computed tomography score and fractionated exhaled nitrogen oxide. Patients with refractory ECRS had higher serum levels of the anti-EPX antibody than those without. However, dupilumab treatment decreased the serum levels of the anti-EPX antibody. Immunoglobulins (Igs) in the immunoprecipitate of mucin supernatants enhanced dsDNA release from eosinophils, whereas the neutralization of Igs against EPX stopped dsDNA release. Furthermore, EPX antibody neutralization accelerated mucin decomposition and restored corticosteroid sensitivity. Taken together, the anti-EPX antibody may be involved in the formulation of eosinophilic mucin and be used as a clinical marker and therapeutic target for intractable eosinophilic airway inflammation.

Abstract
Introduction Asthma is a chronic respiratory condition characterized by inflammation of the airway leading to breathlessness. Exercise training has been recognized as a valuable component in the management of asthma, enhancing lung function and overall well-being. Bicycle ergometer training and Nordic walking are two distinct forms of exercise that have been shown to improve cardiovascular fitness and respiratory function. Despite the potential benefits of these exercises, limited research directly compares their efficacy in improving functional capacity specifically in asthma patients. The study thus aims to address this gap by providing personalized, tailored exercise programs for asthma patients. Methods A single-blinded experimental study using a simple random sampling method was conducted. A sample of 40 subjects was recruited for the study based on inclusion and exclusion criteria and were assigned into two groups. Group A subjects were trained with a bicycle ergometer and Group B subjects were trained with Nordic walking. The intervention was given to both groups for 12 weeks. The outcome measures used were the six-minute walk test, Modified Borg Scale, and Mini Asthma Quality of Life Questionnaire. Results A baseline analysis of outcome measures was done, which was followed up by a post-test analysis after 12 weeks. Pre-test and post-test data were compared using a paired t-test. Intergroup analysis was done by an independent t-test. Both groups showed significant improvement in post-test results. On comparing the two groups, Group A showed significant improvement as compared to Group B. Conclusion The study concludes that bicycle ergometer training is effective in improving functional capacity and enhancing the quality of life in asthma patients.

Abstract
Vasospastic angina (VSA) is a disease that causes myocardial ischemia due to transient vasoconstriction of the epicardial coronary arteries. This disease generally occurs in middle-aged and older adults, but there are also reports of it occurring in young people. We report a case of VSA in a woman in her 20's. Six months ago, a female patient in her 20s became aware of a strangling sensation in the chest that lasted for approximately 1-20 minutes at rest or during stress. She consulted her family doctor who prescribed nitroglycerin sublingual tablets, which were effective. She was a current smoker and had a history of bronchial asthma, with no family history of coronary artery disease. Resting electrocardiogram and echocardiography revealed no clear abnormalities. The patient was referred to our hospital for coronary angiography (CAG) and spasm provocation test (SPT), primarily to thoroughly examine her chest pain at rest. CAG revealed no significant stenosis. A subsequent SPT using acetylcholine demonstrated diffuse coronary spasm in the left anterior descending coronary artery (LAD). The coronary spasm resolved spontaneously, but the catheter was difficult to maneuver owing to the radial artery spasm at the puncture site; thus, nitroglycerin was administered, which alleviated the radial artery spasm. Another SPT was performed on the right coronary artery (RCA) and revealed no coronary spasm. Coronary microcirculatory function using a pressure wire in response to the peripheral infusion of adenosine triphosphate was assessed in the RCA and LAD, both of which were normal. The patient was discharged from the hospital on an oral calcium channel blocker (CCB). She continued to experience chest pain, but her chest symptoms improved with CCB medication and a change in her workplace. It must be kept in mind that coronary spasms can occur even in young women and should be one of the differentials of chest pain in such patients.

Abstract
BACKGROUND Airway remodeling is one of the reasons for severe steroidresistant asthma related to HMGB1/RAGE signaling or Th17 immunity. OBJECTIVE Our study aims to investigate the relationship between the HMGB1/RAGE signaling and the Th17/IL-17 signaling in epithelial-mesenchymal transformation (EMT) of airway remodeling. METHODS CD4+ T lymphocytes were collected from C57 mice. CD4+ T cell and Th17 cell ratio was analyzed by flow cytometry. IL-17 level was detected by ELISA. The Ecadherin and α-SMA were analyzed by RT-qPCR and immunohistochemistry. The Ecadherin, α-SMA, and p-Smad3 expression were analyzed by western blot. RESULTS The HMGB1/RAGE signaling promoted the differentiation and maturation of Th17 cells in a dose-dependent manner in vitro. The HMGB1/RAGE signaling also promoted the occurrence of bronchial EMT. The EMT of bronchial epithelial cells was promoted by Th17/IL-17 and the HMGB1 treatment in a synergic manner. Silencing of RAGE reduced the signaling transduction of HMGB1 and progression of bronchial EMT. CONCLUSION HMGB1/RAGE signaling synergistically enhanced TGF-β1-induced bronchial EMT by promoting the differentiation of Th17 cells and the secretion of IL-17.

Abstract
Introduction Asthma is defined as a chronic inflammatory airway disease. The prevalence of both asthma and obesity has been rising simultaneously, demonstrating a parallel trend. Obesity is a significant factor in metabolic syndrome, and numerous studies have indicated a connection between metabolic syndrome and bronchial asthma. Aims and objectives The aim of this paper is to evaluate the association of asthma with patients diagnosed with metabolic syndrome. The main objectives were to analyze the clinical profile and spirometric indices in patients with metabolic syndrome and to assess asthmatic patients among them with spirometry and clinical parameters at a tertiary care hospital in Chennai. Materials and methods This hospital-based cohort study was conducted on 73 patients attending the outpatient department who had a known case of metabolic syndrome and were evaluated for asthma through history, physical examination, and a pulmonary function test. A history of cough, expectoration, shortness of breath, wheezing, chest tightness, allergy, seasonal variation, and smoking habits was asked, and a thorough physical examination was performed. Bronchial asthma was confirmed with airflow reversibility by spirometry as per the Global Initiative for Asthma Guidelines. Metabolic and spirometry parameters were examined, such as body mass index (BMI), waist circumference, waist-hip ratio, fasting blood sugar (FBS), postprandial blood sugar, hemoglobin A1C (HbA1C), serum insulin, lipid profile, C-reactive protein (CRP), forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), and FEV1/FVC pre- and post-reversibility (baseline vs. six months). Results and discussion The average BMI of all participants was 29.6511 ±2.64564. The waist-hip ratio was 0.5512 ±0.43855, which decreased during the follow-ups, demonstrating a decline in the risk of obesity in study participants. The level of HbA1C showed a drop from 6.1% to 5.9% at the first follow-up. This exhibited a further reduction at the six-month follow-up in addition to a positive reflection in insulin sensitivity, indicating successful control of diabetes among study participants. It was discovered that this was statistically significant (p<0.001). At the third and sixth months of follow-up, the FEV1/FVC ratio increased by 38% and 37%, respectively, when metabolic syndrome was under control. The results show that controlling diabetes, hypertension, obesity, and triglyceride values improved asthmatic symptoms, and this was determined to be statistically significant (p<0.001). Conclusion The results of the current study demonstrated that the regulation and maintenance of metabolic parameters such as BMI, diabetes, hyperlipidemia, and hypertension aid in improving asthma control.

Abstract
Bronchial asthma (BA) is a heterogeneous chronic inflammatory disease of the respiratory tract. Allergic (atopic) asthma is the most common (up to 80% of cases) phenotype developing through the Th2-dependent mechanisms involving cytokines: IL-4, IL-5, IL-9, and IL-13. The genes encoding Th2-cytokines have a mosaic structure (encode exons and introns). Therefore, several mature mRNA transcripts and protein isoforms can be derived from a single mRNA precursor through alternative splicing, and they may contribute to BA pathogenesis. Analysis of the published studies and databases revealed existence of the alternative mRNA transcripts for IL-4, IL-5, and IL-13. The alternative transcripts of IL-4 and IL-5 carry open reading frames and therefore can encode functional proteins. It was shown that not only alternative mRNA transcripts exist for IL-4, but alternative protein isoforms, as well. Natural protein isoform (IL-4δ2) lacking the part encoded by exon-2 was identified. Similarly, alternative mRNA transcript with deleted exon-2 (IL-5δ2) was also identified for IL-5. In this review, we summarize current knowledge about the identified alternative mRNA transcripts and protein isoforms of Th2-cytokinins, first of all IL-4 and IL-5. We have analyzed biological properties of the alternative variants of these cytokines, their possible role in the allergic asthma pathogenesis, and considered their diagnostic and therapeutic potential.

Abstract
Children with stunted growth have an increased risk of wheezing, and studies have shown that low levels of vitamin D and interleukin (IL)-10, along with increased IL-4 levels and CD23+ expression, are present in stunted and asthmatic children. To date, it is not known whether these factors are related to the incidence of asthma in stunted children. This case-control study investigated the association between vitamin D, IL-4, and IL-10 levels and CD23+ expression with bronchial asthma in stunted children. The study included 99 children aged 24-59 months, i.e., 37 stunted-sthmatic children (cases), 38 stunted children without asthma, and 24 non-stunted children with asthma. All children were tested for their 25(OH)D levels using chemiluminescent immunoassay (CLIA), IL-4 and IL-10 levels were measured through enzyme-linked immunosorbent assay (ELISA) testing, and CD23+ expression was measured through flow cytometry bead testing. The data were analyzed using chi-squared, Kruskal-Wallis, and Mann-Whitney tests. The results showed that stunted asthmatic children had a higher incidence of atopic family members than those without asthma. Additionally, stunted asthmatic children had a higher prevalence of vitamin D deficiency (48.6%) than the control group (44.7% and 20.8%). Furthermore, stunted asthmatic children had significantly lower levels of 25(OH)D [20.55 (16.18-25.55), p = 0.042] and higher levels of IL-4 [1.41 (0.95-2.40), p = 0.038], although there were no significant differences in IL-10 levels and CD23+ expression. The study concluded that low vitamin D and high IL-4 levels are associated with bronchial asthma in stunted children, while IL-10 and CD23+ do not show a significant association.

Abstract
OBJECTIVE To investigate the clinical efficacy of the combined application of blistering cupping with thunder-fire moxibustion in treating bronchial asthma of cold-wheezing syndrome, and its influences on airway remodeling, inflammatory factors, lung function, and quality of life on the base of conventional western medicine treatment. METHODS A total of 76 patients with bronchial asthma of cold-wheezing syndrome were randomly divided into an observation group and a control group, 38 cases in each group. In the control group, the basic treatment was used, i.e. budesonide formoterol powder inhalation. In the observation group, on the basis of the treatment as the control group, blistering cupping combined with thunder-fire moxibustion was supplemented, Dazhui (GV 14), Danzhong (CV 17) and bilateral Feishu (BL 13), Gaohuang (BL 43), and Zhongfu (LU 1) were selected; blistering cupping was administered once a day and thunder-fire moxibustion was given twice a day. One course of treatment was composed of 7 days in both groups, and 2 courses of treatment were required. Before and after treatment, the airway remodeling indexes (matrix metalloproteinase-9 [MMP-9], tissue inhibitor of matrix metalloproteinase-1 [TIMP-1], and transforming growth factor-β1 [TGF-β1]) and inflammatory indexes (interleukin [IL] -1β、IL-25) were detected by using radioimmunoassay in the patients of the two groups. The lung function, traditional Chinese medicine symptom score, and asthma quality of life questionnaire (AQLQ) score were observed in the patients of the two groups. RESULTS After treatment, the serum levels of MMP-9, TIMP-1, TGF-β1, IL-1β, IL-25, peak expiratory flow (PEFR), traditional Chinese medicine symptom scores, and AQLQ scores were decreased compared with those before treatment in the patients of the two groups (P<0.05), and the results in the observation group were lower than those in the control group (P<0.05). After treatment, the first second forced expiratory volume (FEV1) and peak expiratory flow rate (PEF) were increased compared with those before treatment in the two groups (P<0.05), and the results in the observation group were higher than those in the control group (P<0.05). CONCLUSION On the basis of the conventional western medicine treatment, the combination of blistering cupping with thunder-fire moxibustion can effectively ameliorate the clinical symptoms of patients, reduce inflammatory levels, inhibit airway remodeling and improve the lung function and quality of life in the patients with bronchial asthma.

Abstract
Background The coronavirus disease 2019 (COVID-19) pandemic impacted various parts of society, including Japanese children with allergies. Objective This study investigated risk factors for pediatric allergic diseases associated with the state of emergency owing to the COVID-19 pandemic in Japan, including during school closures. Methods Parents of pediatric patients (0-15 years) with allergies were enrolled and queried regarding the impact of school closure on pediatric allergies compared to that before the COVID-19 pandemic. Results A valid response was obtained from 2302 parents; 1740 of them had children with food allergies. Approximately 4% (62/1740) of the parents reported accidental food allergen ingestion was increased compared to that before the COVID-19 pandemic. Accidental ingestion during school closures was associated with increased contact with meals containing allergens meant for siblings or other members of the family at home. The exacerbation rate during the pandemic was highest for atopic dermatitis at 13% (127/976), followed by allergic rhinitis at 8% (58/697), and bronchial asthma at 4% (27/757). The main risk factors for worsening atopic dermatitis, allergic rhinitis, and bronchial asthma were contact dermatitis of the mask area (34/120 total comments); home allergens, such as mites, dogs, and cats (15/51 total comments); and seasonal changes (6/25 total comments), respectively. Conclusion The main factors affecting allergic diseases were likely related to increased time at home, preventive measures against COVID-19, and refraining from doctor visits. Children with allergies were affected by changes in social conditions; however, some factors, such as preventing accidental ingestion and the management of allergens at home, were similar to those before the COVID-19 pandemic. Patients who had received instructions on allergen avoidance at home before the pandemic were able to manage their disease better even when their social conditions changed.

Abstract
A 46-year-old man with a history of bronchial asthma and chronic sinusitis presented to our hospital with chest pain. We suspected angina evoked by epicardial coronary spasm and performed an ergonovine provocation test to diagnose coronary spastic angina (CSA). The patient also met the diagnostic criteria for eosinophilic granulomatosis with polyangiitis (EGPA) and was treated with 60 mg prednisolone (PSL) for EGPA-associated CSA. After PSL administration, eosinophils decreased, and angina attacks disappeared. However, when PSL was tapered to 12.5 mg, chest pain recurred. We administered mepolizumab subcutaneously and chest pain disappeared. Additional mepolizumab may be effective for EGPA with CSA.

Abstract
Specific work environments, such as exposure to chemicals emitted during industrial processes, are related to occupational asthma. From 1985 to 2012, Kuwait was expected to have the highest asthma prevalence rate among Middle East nations, at 15%. This cross-sectional study was conducted using secondary data from occupational health physicians' records in the Shuaiba Industrial Medical Center (SIMC) extracted and analyzed using SPSS. Chi-square test and logistic regression were used to check the association between risk factors and bronchial asthma (BA). The data sample size was 3478 in 2018 and 3807 in 2019. In 2018, BA had a significant relationship with age categories, work year groups, and determinants of fitness. Migrant workers above 51 years of age had a high risk of developing BA (p-value = 0.012). There was a high risk of developing BA in workers who worked > 21 years (p-value < 0.001) and in workers who worked between 11 and 20 years (p-value = 0.042). Overweight workers had a risk of developing BA (p-value = 0.042). In 2019, BA had an associated relationship with age categories and determinants of fitness. Workers above 51 years of age had about a 39% risk of developing BA (p-value = 0.009). Otherwise, the BMI, working year groups, marital status, and smoking status had no association with BA. In conclusion, BA is prevalent among migrant workers at the SIMC. Long hours, low income, and a lack of PPE are just a few of the issues that migrant workers have been exposed to, raising their risk of poor health.

Abstract
BACKGROUND AND AIM Bronchial asthma is a prevalent type of respiratory disease that affects a large proportion of pediatric patients. The purpose of this study is to further investigate the clinical effects of budesonide combined with montelukast sodium in treating bronchial asthma. METHODS Eighty six children with bronchial asthma were equally divided into study and control groups via randomized double-blind controlled trial. The control group was treated with aerosol inhalation of budesonide combined with placebo, while the study group was treated with budesonide combined with montelukast sodium. Pulmonary function parameters, immunoglobulin, and recovery of related symptoms, along with the adverse reaction rate, were observed and compared between both groups. RESULTS Before treatment, there was no marked difference in pulmonary function parameters and immunoglobulin indexes between both groups (P > 0.05). All pulmonary function indicators and immunoglobulin indexes in both groups improved following therapy, with the study group outperforming the control group (P < 0.05). The recovery time of related symptoms in the study group was shorter than that in the control group (P < 0.05). The incidence of adverse reactions in both groups was compared, with notable differences (P < 0.05). CONCLUSION Budesonide combined with montelukast sodium in the treatment of bronchial asthma has the value of clinical application and promotion.

Abstract
The intensive impact of anthropogenic factors on health causes more than 40% of all human diseases. First of all, it has to do with respiratory organs and comes out as the main determinant of development of chronic respiratory pathology. The article presents an assessment of negative impact of environmental factors on dynamics of increasing of incidence of bronchial asthma morbidity in the Republic of North Ossetia-Alania. The indicators of the general morbidity that increased up to 75.6% and for the first time detected up to 97.5% over six-year period. The results of present study correspond with the results of similar studies implemented in various territories of Russia indicating at mediation of increasing of bronchial asthma morbidity by negative impact of environment risk factors. In the Republic, over a period of many decades, contribution of the metallurgical plant producing zinc, cadmium, sulfuric acid and zinc-aluminum alloys, to atmospheric air pollution made up not less than 40%. Only two out of eight rural municipal districts are relatively environmentally problem-free today. In rural areas, more than 50% of atmospheric air pollutants is related to carbon oxide. Nowadays, along with industrial emissions into atmospheric air and their accumulation, increases importance of motor transport in environmental pollution. The cars account for 50-70% of all harmful emissions. The presence of harmful substances contained in exhaust gases exceeds permissible standards by 2-3 times. According to the data of systematic analysis of urban air quality, most of the year citizens breathe atmospheric air not meeting normative requirements. The actual situation favors development of bronchial asthma. In the Republic, its morbidity has not decreased for many decades. To improve indicators of bronchial asthma morbidity can be achieved by leveling harmful effects of environment through identification of main sources of environmental troubles. The priority is both to decrease industrial emissions that pollute atmosphere and to transit to more ecologically safe modern power supplies of motor transport facilities.

Abstract
Bronchial asthma is a complex heterogeneous airway disease, which has emerged as a global health issue. A comprehensive understanding of the different molecular mechanisms of bronchial asthma may be an efficient means to improve its clinical efficacy in the future. Increasing research evidence indicates that some types of programmed cell death (PCD), including apoptosis, autophagy, pyroptosis, ferroptosis, and necroptosis, contributed to asthma pathogenesis, and may become new targets for future asthma treatment. This review briefly discusses the molecular mechanism and signaling pathway of these forms of PCD focuses on summarizing their roles in the pathogenesis and treatment strategies of asthma and offers some efficient means to improve clinical efficacy of therapeutics for asthma in the near future.

Abstract
Inducible laryngeal obstruction (ILO)/paradoxical vocal fold motion (PVFM) is a reversible narrowing of the larynx that results from vocal fold motion dysfunction. Distinguishing ILO from asthma can be challenging, as they can coexist, and standard tests may not be able to differentiate between the two. However, a flexible laryngoscopy can promptly diagnose ILO. Unfortunately, ILO is often overlooked as a potential cause when evaluating patients with sudden-onset breathing difficulties and respiratory distress. We present a case of a young female who sought frequent treatment at the emergency room (ER) with symptoms of shortness of breath (SOB), rapid heart rate, rapid breathing, and anxiety. Despite receiving treatment for acute asthma attacks, her symptoms persisted. During her most recent hospital admission, a flexible laryngoscopy revealed abnormal vocal fold movements, indicating paradoxical vocal fold dysfunction (PVFD) and muscle tension dysphonia (MTD). A comprehensive treatment approach involving speech therapy, pulmonology, and psychiatry led to significant clinical improvement. This case report highlights the importance of raising awareness among healthcare providers about ILO potentially mimicking bronchial asthma exacerbation.

Abstract
Objectives Airway remodeling in asthma involves chronic inflammation associated with structural changes, which result in severe airflow limitation and very few therapeutic options. Thus, the present study was designed to experimentally evaluate the ameliorative effects of Withania somnifera (WS) root extract against Ovalbumin (OVA)-induced airway remodeling in a rat model of asthma. Methods Wistar rats were immunized (i.p) and challenged (aerosol) with ovalbumin (OVA), and the effects of WS extract were investigated on the development and progress of airway remodeling by assessing immunological, biochemical, and histological changes in these rats. Results OVA-immunization and challenge in rats resulted in significant increases in the levels of IL-13, 8-OhdG, TGF-β, hydroxyproline, and periostin in bronchoalveolar lavage fluid (BALF) and serum/lung homogenate compared to normal control (saline only) rats, and these changes were attenuated after WS extract (200 and 400 mg/kg), as well as dexamethasone (DEX, 1 mg/kg) pretreatments. Further, WS extract attenuated histopathological changes and maintained lung integrity. In herb-drug interactions, sub-threshold doses of WS extract and DEX showed synergistic effects on all parameters studied as compared to either form of monotherapy. Conclusion These results indicated that WS exerted significant protective effects against airway remodeling in the experimental model by modulating inflammatory and fibrotic cytokines, and could have the potential for developing a therapeutic alternative/adjunct for the treatment of airway remodeling of bronchial asthma.

Abstract
INTRODUCTION Bronchial asthma (BA) is a heterogeneous disease characterized by chronic airway inflammation. This study investigated the serum miR-27a-3p/activating transcription factor 3 (ATF3) expression in children with BA and their correlations with airway inflammation. METHODS Children with BA (N = 120) and healthy children (N = 108) were enrolled. Serum levels of interleukin (IL)-17, IL-6, tumor necrosis factor (TNF)-α, immunoglobulin E (IgE), miR-27a-3p, ATF3, and the number of eosinophils (EOS) were measured using enzyme-linked immunosorbent assay (ELISA), reverse transcription quantitative polymerase chain reaction (RT-qPCR), and an automatic hematology analyzer. The correlations between miR-27a-3p and ATF3 and between miR-27a-3p/ATF3 and inflammation-related factors were analyzed by the Pearson method. The diagnostic values of miR-27a-3p and ATF3 in BA were evaluated using receiver operating characteristic (ROC) curves. The influencing factors of BA were assessed using multivariate logistic regression. Finally, the targeting relation between miR-27a-3p and ATF3 was predicted and analyzed by TargetScan and Starbase databases, and dual-luciferase assay. RESULTS There were significant differences in forced expiratory volume in 1 s (FEV1)% predicted and FEV1/forced vital capacity (FVC)%, serum levels of IgE, IL-17, IL-6, and TNF-α, and EOS numbers between healthy children and BA children. Serum miR-27a-3p was negatively correlated with ATF3 and positively correlated with inflammation-related factors in BA children. Serum ATF3 mRNA levels were negatively correlated with inflammatory factors in BA children. miR-27a-3p and ATF3 had good diagnostic values in BA children. FEV% predicted, IL-6, TNF-α, miR-27a-3p, and ATF3 were independent risk factors for BA. miR-27a-3p targeted ATF3. CONCLUSION Serum miR-27a-3p was highly expressed, whereas ATF3 was poorly expressed in BA children, and they were significantly correlated with airway inflammation, had good diagnostic values in BA children, and were independent risk factors for asthma.

Abstract
Prosperous advances in understanding the cellular and molecular mechanisms of chronic inflammation and airway remodeling in asthma have been made over the past several decades. Asthma is a chronic inflammatory disease of the airways characterized by reversible airway obstruction that is self-resolving or remits with treatment. Around half of asthma patients are "Type-2-high" asthma with overexpression of type 2 inflammatory pathways and elevated type 2 cytokines. When stimulated by allergens, airway epithelial cells secrete IL-25, IL-33, and TSLP to derive a Th2 immune response. First ILC2 followed by Th2 cells produces a series of cytokines such as IL-4, IL-5, and IL-13. TFH cells control IgE synthesis by secreting IL-4 to allergen-specific B cells. IL-5 promotes eosinophil inflammation, while IL-13 and IL-4 are involved in goblet cell metaplasia and bronchial hyperresponsiveness. Currently, "Type-2 low" asthma is defined as asthma with low levels of T2 biomarkers due to the lack of reliable biomarkers, which is associated with other Th cells. Th1 and Th17 are capable of producing cytokines that recruit neutrophils, such as IFN-γ and IL-17, to participate in the development of "Type-2-low" asthma. Precision medicine targeting Th cells and related cytokines is essential in the management of asthma aiming at the more appropriate patient selection and better treatment response. In this review, we sort out the pathogenesis of Th cells in asthma and summarize the therapeutic approaches involved as well as potential research directions.

Abstract
PURPOSE Junctional adhesion molecule (JAM)-A is an immunoglobulin-like molecule that colocalizes with tight junctions (TJs) in the endothelium and epithelium. It is also found in blood leukocytes and platelets. The biological significance of JAM-A in asthma, as well as its clinical potential as a therapeutic target, are not well understood. The aim of this study was to elucidate the role of JAM-A in a mouse model of asthma, and to determine blood levels of JAM-A in asthmatic patients. MATERIALS AND METHODS Mice sensitized and challenged with ovalbumin (OVA) or saline were used to investigate the role of JAM-A in the pathogenesis of bronchial asthma. In addition, JAM-A levels were measured in the plasma of asthmatic patients and healthy controls. The relationships between JAM-A and clinical variables in patients with asthma were also examined. RESULTS Plasma JAM-A levels were higher in asthma patients (n=19) than in healthy controls (n=12). In asthma patients, the JAM-A levels correlated with forced expiratory volume in 1 second (FEV1%), FEV1/forced vital capacity (FVC), and the blood lymphocyte proportion. JAM-A, phospho-JNK, and phospho-ERK protein expressions in lung tissue were significantly higher in OVA/OVA mice than in control mice. In human bronchial epithelial cells treated with house dust mite extracts for 4 h, 8 h, and 24 h, the JAM-A, phospho-JNK, and phospho-ERK expressions were increased, as shown by Western blotting, while the transepithelial electrical resistance was reduced. CONCLUSION These results suggest that JAM-A is involved in the pathogenesis of asthma, and may be a marker for asthma.

Abstract
BACKGROUND Interleukin-33 (IL-33) exacerbates asthma probably through type 2 innate lymphoid cells (ILC2s). Nevertheless, the association between eosinophilic asthma (EA) and ILC2s remains obscure, and the mechanisms by which IL-33 affects ILC2s are yet to be clarified. METHODS ILC2s were evaluated in peripheral blood mononuclear cells, induced sputum, and bronchoalveolar lavage fluid obtained from patients with EA. Confocal microscopy was performed to locate ILC2s in lung tissue and the mRNA expression of ILC2-related genes was also evaluated in the EA model. The proliferation of ILC2s isolated from humans and mice was assessed following IL-33 or anti-IL-33 stimulation. RESULTS The counts, activation, and mRNA expression of relevant genes in ILC2s were higher in PBMCs and airways of patients with EA. In addition, ILC2 cell counts correlated with Asthma control test, blood eosinophil count, Fractional exhaled nitric oxide level, and predicted eosinophilic airway inflammation. IL-33 induced stronger proliferation of ILC2s and increased their density around blood vessels in the lungs of mice with EA. Moreover, IL-33 treatment increased the counts and activation of ILC2s and lung inflammatory scores, whereas anti-IL-33 antibody significantly reversed these effects in EA mice. Finally, IL-33 enhanced PI3K and AKT protein expression in ILC2s, whereas inhibition of the PI3K/AKT pathway decreased IL-5 and IL-13 production by ILC2s in EA. CONCLUSIONS ILC2s, especially activated ILC2s, might be critical markers of EA. IL-33 can induce and activate ILC2s in the lungs via the PI3K/AKT pathway in EA. Thus, using anti-IL-33 antibody could be a part of an effective treatment strategy for EA.

Abstract
INTRODUCTION Epidemiological studies demonstrated that cleaning work and frequent use of cleaning products are risk factors for asthma. Laundry detergents have been reported to have epithelial barrier-opening effects. However, whether laundry detergents directly induce airway inflammation and its mechanisms in vivo remain to be elucidated. METHODS Two commercial laundry detergents and two commonly-used surfactants for cleaning and cosmetics (sodium lauryl sulfate and sodium dodecyl benzene sulfonate) were intranasally administered to mice. Lungs were analyzed using flow cytometry, histology, ELISA, and quantitative PCR. Human bronchial epithelial cells were stimulated with laundry detergents and analyzed using quantitative PCR and western blotting. Involvement of oxidative stress was assessed using an antioxidant. Dust samples from homes were analyzed to determine their detergent content by measuring their critical micelle concentration (CMC). RESULTS The administered laundry detergents and surfactants induced eosinophilic airway inflammation accompanied by increased IL-33 expression and activation of group 2 innate lymphoid cells (ILC2s). Detergent-induced eosinophilic airway inflammation was significantly attenuated in Rag2-/- Il2rg-/- , Il33-/- mice, and also in wild-type mice treated with NAC. Detergent-induced IL-33 expression in airways was attenuated by NAC treatment, both in vivo and in vitro. CMCs were found in all of the tested dust extracts, and they differed significantly among the homes. CONCLUSION The laundry detergents and surfactants induced eosinophilic airway inflammation in vivo through epithelial cell and ILC2 activation. They induced IL-33 expression in airway epithelial cells through oxidative stress. Furthermore, detergent residues were present in house dust and are presumably inhaled into the airway in daily life.

Abstract
Background Asthma has brought great economic burdens to community. Artesunate has shown certain effects on asthma experimentally, but relevant mechanisms are not clear. This study aims to systemically evaluate the efficacy and safety of artesunate and its metabolite, dihydroartemisinin (DHA), in asthma, based on network pharmacology and molecular docking. Methods All the information before March 1st, 2022 was collected. We evaluated the physicochemistry and Adsorption, Distribution, Metabolism, Excretion, and Toxicity (ADMET) properties of artesunate and DHA by SwissADME and ADMETlab, identified targets of artesunate and DHA from SwissTargetPrediction and PharmMapper, and acquired genes participating in asthma from GeneCards and DisGeNET. Overlapping targets and hub genes were identified with Maximal Clique Centrality (MCC) algorithm in Cytoscape, cytoHubba. Enrichment analyses were performed to analyze the potential mechanisms and target sites. Molecular docking was utilized to investigate the receptor-ligand interactions on Autodock Vina and visualized in PyMOL. Results Artesunate and DHA showed acceptable druglikeness and safety for clinical application. A total of 282 targets of compounds and 7,997 targets of asthma were identified. 172 overlapping targets were visualized in a compound-target and protein-protein interaction network. Biofunction analysis showed the clustering associations with biosynthesis and metabolism of and response to steroid hormone, immune and inflammatory response, airway hyperresponsiveness, airway remodeling and cell survival and death regulation. CCND1, CASP3, MTOR, ERBB2, MAPK3, EGFR, MAP2K1, PTGS2, JAK2, and CASP8 were identified as the hub targets. Molecular docking indicated 10 stable receptor-ligand interactions, except for CASP3. Conclusions Artesunate has the potential to be a potent and safe anti-asthmatic agent based on diverse therapeutic mechanisms and acceptable safety.

Abstract
OBJECTIVE Among animals defined as "pests", cockroaches and rodents (mouse and rat) represent the most common cause of airway allergic sensitization and bronchial asthma worldwide. Their frequency of sensitization has been widely assessed in US and other countries but poorly in Western Europe. This narrative review aims to provide a synthesis of data resulting in MEDLINE concerning allergic sensitization/asthma to pests as well as their related environmental/social risk factors, specifically in the European area.Data Sources: We performed a literature research in MEDLINE for clinical trials, randomized controlled trials, systematic reviews and meta-analyses.Study Selections: We selected studies to the following key words: allergic sensitization, allergic rhinitis, bronchial asthma, cockroach, hypersensitivity, integrated pest management, material hardship, medication compliance, mouse, pest, poverty, rat, rodents. RESULTS Current evidence indicates that residence in poor and urban areas, exposure to outdoor/indoor pollutants and tobacco smoke, poverty, material hardship, poor-quality housing, differences in health care quality, medication compliance, heath care access contribute to increased pest-related allergic sensitization and asthma morbidity. CONCLUSION Further research should be done on many aspects of pest allergy such as a better characterization of allergens and epidemiological aspects. Relevant social actions should be carried out against poverty, healthcare disparities, psycho-social stress, poor compliance to therapy, with economic contributions to improve private and public living environments. Allergic sensitization to pests and pest-allergic respiratory diseases like asthma are "paradoxical" conditions, as they typically affect the poorest communities but can only be corrected by high-cost (diagnostic and preventive) interventions. We hope that progress can be made in this direction in the future.

Abstract
The course of bronchial asthma can be accompanied by cognitive impairments. However, the relationship between cognitive dysfunction and asthma has not been fully revealed, nor has it been fully established what causes cognitive impairments in patients with asthma. There is an opinion that transient hypoxia and persistent systemic inflammation with insufficient control of bronchial asthma can be accompanied by neurotoxicity in relation to the hippocampus and indirectly lead to deterioration of cognitive functions. Comorbid conditions, such as obesity, allergic rhinitis, and depressive states can increase cognitive dysfunction in asthmatics. The review considers the pathophysiology of cognitive dysfunction in patients with bronchial asthma, as well as the impact of comorbid conditions on the cognitive status. This information will allow systematizing the available knowledge about the state of cognitive functions in asthma for timely detection and correction of their impairments and, ultimately, optimization of the management of these patients.

Abstract
BACKGROUND Atopic march is defined as the progression from atopic dermatitis (AD) during early life to other allergic diseases in later childhood. In a nationwide birth cohort study, the Japan Environment and Children's Study, we investigated the association of bathing habits, which are known to affect skin conditions, for infants with their later development of allergic diseases. METHODS Pregnant women who lived in 15 designated regional centers throughout Japan were recruited. We obtained information on bathing habits for their 18-month-old infants and the prevalence of allergic diseases when they were aged 3 years. RESULTS Data for 74,349 children were analyzed. Most 18-month-old infants were bathed or showered almost every day. When they were divided into four groups according to the frequency of soap use during bathing (every time, most of the time, sometimes, and seldom), the risk of AD later at age 3 was shown to increase in association with a decreasing frequency of soap use [most of the time: adjusted odds ratio (aOR) 1.18, 95% confidence interval (CI) 1.05-1.34; sometimes: aOR 1.72, 95% CI 1.46-2.03; seldom: aOR 1.99, 95% CI 1.58-2.50], compared with soap use every time during bathing at 18 months of age. Similar results were obtained for food allergy but not for bronchial asthma. CONCLUSIONS Frequent soap use when bathing 18-month-old infants was associated with a decreased risk of them developing allergic diseases at age 3. Further well-designed clinical studies are warranted to determine an effective bathing regimen for preventing the development of allergic diseases.

Abstract
Background ABO blood group types are hereditary factors that have been shown to affect the blood levels of many antigens and proteins. Some blood groups have surprisingly been shown to be associated with some specific diseases, probably due to yet unexplained altering effects on the immune system or on the levels of other system-specific proteins. Studies conducted previously attempting to relate bronchial asthma and blood groups have had variable results and such studies on a large scale have not been ventured in India. Hence, the significance of the current study, which aims to search for an increased occurrence of bronchial asthma in any one of the ABO blood group phenotypes and additionally in Rh blood groups. Objective The objective of this study was to analyze the possible association of the ABO and Rh blood group types with bronchial asthma. Methods This is an observational study with 475 bronchial asthma patients, and 2052 non-asthmatic individuals belonging to the same geographical zone. After obtaining informed consent, ABO and Rh Blood group testing was done on the study subjects using the hemagglutination method. Chi-squared tests were employed for the comparison of proportions. Statistical significance was agreed upon for an error of 5%. Results The O blood group was predominant in both cases (46.9 %) and controls (36.1%). A chi-square analysis revealed a statistically significant higher percentage of O blood group in patients (χ2: 24.537; degrees of freedom (DF): 3; p-value = <0.01). The cases had more Rh -ve individuals (12%) than controls (8%), which too was statistically significant (χ2: 6.711; degrees of freedom (DF): 1; p-value = 0.01). Conclusion The present study shows a positive association between the O blood group and the Rh-negative blood group with bronchial asthma.

Abstract
BACKGROUND We examined the associations between factors evident at the routine 3-month well child visit (WCV) and the risk of developing 36-month parent-reported physician-diagnosed bronchial asthma (BA). METHODS This longitudinal study was conducted in Nagoya City, Japan, and included 40,242 children who qualified for the 3-month WCVs in the city between April 1, 2016 and March 31, 2018. In total, 22,052 (54.8%) questionnaires linked to their 36-month WCVs were analyzed. RESULTS The prevalence of BA was 4.5%. The multivariable Poisson regression model identified male sex (adjusted risk ratio [aRR], 1.59; 95% confidence interval [CI]: 1.40-1.81), born in autumn (aRR, 1.30; 95% CI: 1.09-1.55), having at least one sibling (aRR, 1.31; 95% CI: 1.15-1.49), wheeze history before 3-month WCVs [with clinic/hospital visit: aRR, 1.99; 95% CI: 1.53-2.56; hospitalization: aRR, 2.99; 95% CI: 2.09-4.12], eczema with itch (aRR, 1.51; 95% CI: 1.27-1.80), paternal history of BA (aRR, 1.98; 95% CI: 1.66-2.34), maternal history of BA (aRR, 2.11; 95% CI: 1.77-2.49), and rearing pets with fur (aRR, 1.35; 95% CI: 1.15-1.58) were independent risk factors for BA at 36 months of age. The combination of severe wheeze history (with clinic/hospital visit or hospitalization) and maternal and paternal BA could identify high-risk infants whose prevalence of BA was 20%. CONCLUSIONS The combined assessment of important clinical factors enabled us to identify high-risk infants set to derive optimal benefit from health guidance provided to the parent or caregiver of the child or infant at WCVs.

Abstract
Summary At the beginning of SARS-CoV 2 pandemic, in the absence of "targeted" therapies, the national health authorities have introduced some measures aimed at reducing the spread of infection in the community (lockdown, social distancing, personal protective equipment (PPE), personal hygiene and disinfection of living environments). All the containment measures have led to both positive and negative effects in patients with allergic diseases. We believe that further studies should be undertaken to investigate the possible correlations between SARS-CoV-2 infection and allergy, from a broader perspective. In particular, the risk factors for the development of undesirable effects should be investigated, especially in healthcare professionals forced to use PPE and sanitizing agents for a long time. However, since the COVID-19 pandemic probably will not be short-lived, the use of such protective aids will necessarily be widespread even in the general population. Therefore, further studies on the materials used for the production of PPE and sanitizing agents would be necessary to reduce their sensitizing and, in some cases, toxic potential.

Abstract
Tracheomalacia (TM) is an abnormal collapse of the tracheal lumen, which often occurs when the cartilaginous part of the trachea has not developed. It is a rare condition but is seen often in infancy and childhood period. The incidence of primary airway malacia in children was estimated to be at least one in 2,100. It has a wide range of etiologies, and it is often localized but rarely generalized as in our case. It could be severe enough to indicate frequent admission and might expose the patient to multiple unnecessary medications. We are reporting a case with unusual primary tracheobronchomalacia (TBM) that was missed for several years with a huge burden on both families and healthcare providers. A five-year-old Saudi girl had multiple admissions to the intensive care unit with similar presentation each time, and she was misdiagnosed as having asthma exacerbation with an occasional chest infection. Bronchoscopy revealed the underlying condition, and the patient was kept on the minimal intervention of nasal continuous positive airway pressure (CPAP) and aggressive airway hydration therapy, all with the goal of improving the patient's outcome and reducing hospital admissions. We emphasize the importance of alerting physicians about malacia as an important cause of recurrent wheezy chest, which is one of the common asthma mimickers; in such cases, flexible bronchoscopy remains the gold standard diagnostic test, while the treatment remained supportive.

Abstract
BACKGROUND Allergic diseases such as bronchial asthma, allergic rhinitis, and atopic dermatitis are common health problems among children. The prevalence of different allergic diseases is increasing in the Kingdom of Saudi Arabia. OBJECTIVES This study aimed to estimate the prevalence and risk factors of allergic diseases among school students in Tabuk, Saudi Arabia. METHODS This cross-sectional analytical study was conducted in Tabuk city, Saudi Arabia, between the first of August and the end of September, 2022. Students from primary, intermediate, and secondary schools were included. A predesigned, structured, self-administered questionnaire in the Arabic language was used to collect data. RESULTS This study included 384 school students from Tabuk, Saudi Arabia. The age of the recruited students ranged from five to 19 years old. The prevalence of clinically diagnosed bronchial asthma that occurred at any time in the past was 31.8%. The prevalence of asthma symptoms was 51.0% for lifetime wheezing and 45.8% for current wheezing (in the past 12 months). The prevalence rates of clinically diagnosed allergic rhinitis and atopic dermatitis were 56.8% and 30.2%, respectively. Further, 68.2% of the school students had one or more of the diagnosed allergic diseases. The second or more childbirth orders were significantly associated with an increased risk of allergic diseases (adjusted odds ratio [AOR] = 3.140, 95% CI: 1.864-5.288). A family history of asthma or atopic conditions showed 3.118 times increased likelihood of allergic conditions (AOR = 3.118, 95% CI: 1.827-5.320). Other significant risk factors were the father's smoking (AOR = 1.698, 95% CI: 1.024-2.817) and having a dog, cat, or bird at home (AOR = 0.493, 95% CI: 0.257-0.946). CONCLUSION The prevalence of bronchial asthma and other allergic diseases such as allergic rhinitis and atopic dermatitis among school students in Tabuk city, Saudi Arabia, is alarmingly high. Furthermore, both genetic and environmental components of allergic disease pathogenesis have been identified as risk factors.

Abstract
Background and Objectives: Bronchial asthma (BA) and chronic obstructive pulmonary disease (COPD) are not only common obstructive respiratory conditions but also major causes of morbidity and mortality worldwide. There is, however, a surprising lack of blood-based biomarkers for separating between these pulmonary disorders. The aim of this study was to assess the practical relevance of using serum YKL-40, single or combined, for this purpose. Materials and Methods: Subjects included Romanian patients with BA (n = 24) or COPD (n = 27). YKL-40, fibrinogen, pre-treatment C-reactive protein (CRP), post-treatment CRP, erythrocyte sedimentation rate, interleukin 6 (IL-6), procalcitonin (PCT), absolute neutrophil count, neutrophil percentage, absolute lymphocyte count, lymphocyte percentage, absolute eosinophil count, and eosinophil percentage were measured and compared between these patients. Results: This is the first study investigating the clinical significance of serum YKL-40 in delineating between COPD and BA in Caucasian populations. Only fibrinogen and YKL-40 levels were different between COPD and BA, with the measured values being significantly elevated. These patients exhibited distinct inflammatory profiles. Using the upper quartiles of these variables for the pooled study population (YKL-40: 5100 pg/mL; fibrinogen: 552 mg/dL) as cut-off values, subjects were classified into high or low groups. High YKL-40 adults revealed significantly increased PCT levels. High fibrinogen subjects, by contrast, showed significantly elevated IL-6 concentrations and pre-treatment CRP levels. Low YKL-40 and fibrinogen patients showed the absence of COPD. Conclusions: Combined use of serum YKL-40 and fibrinogen may be useful for identifying the absence of COPD.

Abstract
Epidemiological data indicate the active progression of various forms of diabetes mellitus in patients with bronchial asthma (BA), but little is known about the mechanisms of comorbidity formation. TLR2 and TLR4 are involved in the progression of asthma and type 2 diabetes mellitus (T2DM). These receptors are involved in the inflammatory response to Gram(+) and Gram(-) bacteria, respectively, so changes in their expression may affect the predisposition of patients to bacteremia. The aim of this study was to analyze the expression and functional activity of toll-like receptor 2 and 4 (TLR2 and TLR4) on peripheral blood cells of patients with BA, T2DM, and BA + T2DM. The expression of TLR2 and TLR4 was analyzed by flow cytometry. Whole blood samples were incubated with lipopolysaccharides from E. coli (LPS) and lipoteichoic acid from S. pyogenes (LTA). The concentration of cytokines and soluble blood proteins was determined by ELISA. Patients with comorbid diseases showed a statistically significant increase in TLR2 expression on both monocytes and neutrophils compared with healthy donors and patients with BA. We found increased expression of TLR4 on the surface of blood monocytes from patients compared to donors. The activation of blood cells of patients and donors with LPS or LTA led to an increase in the expression of "fast" pro-inflammatory cytokines (TNF-α, IL-6). In patients with BA, the average production of TNF-α in response to endotoxin was two times higher than in other studied groups. The reactions of blood cells in patients with T2DM and BA + T2DM did not differ significantly. The expression and functional activity of TLR2 and TLR4 on the blood cells of patients with comorbid disease were similar to those only in patients with T2DM. The greatest increase in the synthesis of the pro-inflammatory cytokine TNF-α in response to LPS and LTA was observed in patients with BA, which can lead to an inadequate response to bacteremia.

Abstract
BACKGROUND Inducible laryngeal obstruction (ILO) refers to respiratory disorders caused by airflow limitation in the larynx, including vocal cord dysfunction, and may sometimes be misdiagnosed as bronchial asthma (BA). Here, we report the case of an 11-year-old boy diagnosed with BA in infancy. He was referred to our Allergy Center and was taking a high dose of inhaled corticosteroids (ICS) due to frequent coughing from the age of 10 years and persistent coughing following COVID-19 infection at the age of 11. However, the patient continued to experience frequent coughing attacks and repeated visits to the emergency department after inhalation of β2-stimulants failed to improve his cough. We admitted him to the allergy center for examinations to assess the BA severity. In the airway hypersensitiveness test, saline inhalation performed prior to methacholine inhalation caused expiratory stridor and respiratory distress in the larynx, which worsened with β2-stimulant inhalation. Based on these results, we ruled out BA and diagnosed ILO. We instructed him on breathing maneuvers, and he was able to respond appropriately when symptoms appeared. We then started reducing his ICS dose.

Abstract
Eosinophilic esophagitis (EoE) is a chronic, Th2-inflammatory disease of the esophagus that can severely affect food intake. Currently, diagnosis and assessing response to treatment of EoE is highly invasive and requires endoscopy with esophageal biopsies. Finding non-invasive and accurate biomarkers is important for improving patient well-being. Unfortunately, EoE is usually accompanied by other atopies, which make it difficult to identify specific biomarkers. Providing an update of circulating EoE biomarkers and concomitant atopies is therefore timely. This review summarizes the current knowledge in EoE blood biomarkers and two of its most common comorbidities, bronchial asthma (BA) and atopic dermatitis (AD), focusing on dysregulated proteins, metabolites, and RNAs. It also revises the current knowledge on extracellular vesicles (EVs) as non-invasive biomarkers for BA and AD, and concludes with the potential use of EVs as biomarkers in EoE.
