Asthma is a high-risk disease based on airway hyperresponsiveness (AHR). In this review, we found that there are many studies on clinical therapy for asthma that focus on the efficacy of acupuncture therapy and its mechanisms, including the functional connectivity of different brain regions, with the aid of functional magnetic resonance imaging (fMRI), immune responses/cell recognition (innate lymphoid cells and balance of Th1/Th2 and Treg/Th17), intracellular mechanism (autophagy, endoplasmic reticulum stress, and epigenetic alteration), and ligand-receptor/chemical signaling pathway (neurotransmitter, hormone, and small molecules)...

BACKGROUND: Allergic rhinitis (AR) is a chronic inflammatory disease of the nasal mucosa. However, few studies focus on the distributional characteristics of allergens in AR patients in Southern Fujian Province, China. METHODS: A skin prick test (SPT) was performed and eight common allergens including Dermatophagoides farinae ( Df), Dermatophagoides pteronyssinus ( Dpt ), weeds, animal dander, molds, cockroaches, and mangoes were chosen. RESULTS: The positive reactions rate to the allergens was 65...

PURPOSE: Recent studies imply that psychological factors may actively contribute to the development of asthma. It is generally known that people with asthma frequently suffer from psychological illnesses. This association can make it challenging to reach asthma control. This study aimed to assess the prevalence of depression and anxiety among Jordanian adults with asthma, in addition to the link between asthma control levels and these psychological disorders. PATIENTS AND METHODS: This cross-sectional study included 175 adults with asthma who visited the tertiary asthma clinic in three Jordanian Governmental hospitals...

PURPOSE: Little research has explored the proteomic characteristics of nasal lavage fluid from asthmatic patients. This study aims to investigate whether differentially expressed proteins (DEPs) in nasal lavage fluid can serve as a biomarker to differentiate asthma patients from healthy controls (HCs) and to discern between individuals with well controlled and poorly controlled asthma. PATIENTS AND METHODS: We enrolled patients with allergic rhinitis (AR), asthma, or both conditions, and HCs in this study...

Severe chronic rhinosinusitis with nasal polyposis (CRSwNP) is a disabling airway disease that significantly impacts patients' lives through the severity of symptoms, the need for long-term medical treatment and the high risk of recurrence post-surgery. Biological agents targeting type 2 immune responses underlying the pathogenesis of CRSwNP have shown effectiveness in reducing polyp size and eosinophilic infiltrate, and in decreasing the need for additional sinus surgeries. However, despite recent progress in understanding and treating the disease, type 2 inflammation-driven severe CRSwNP continues to pose challenges to clinical management due to several factors such as persistent inflammation, polyp recurrence, heterogeneity of disease, and comorbidities...

PURPOSE: Patients living with severe asthma (SA) experience multiple health-related quality of life (HRQoL) impairments. This study examined HRQoL changes after biologic treatment initiation among a large, real-world cohort of patients with SA. PATIENTS AND METHODS: CHRONICLE is an ongoing observational study of subspecialist-treated adults with SA who receive biologics or maintenance systemic corticosteroids or are uncontrolled on high-dosage inhaled corticosteroids with additional controllers...

OBJECTIVE: Prediction of asthma in preschool children is challenging and lacks objective indicators. The aim is to observe and analyze the variances between impulse oscillometry (IOS) and fractional expiratory nitric oxide (FeNO) in preschool children with wheezing, establish a joint prediction model, and explore the diagnostic value of combining IOS with FeNO in diagnosing asthma among preschool children. PATIENTS AND METHODS: This study enrolled children aged 3-6 years with wheezing between June 2021 and June 2022...

BACKGROUND: Patients with asthma experience more physical, psychological, and financial burdens; a link between asthma and suicidality has been reported in research. PURPOSE: This study analyzed the medical utilization and comorbidity before their self-injurious behavior in patients with asthma. METHODS: We enrolled 186,862 patients newly diagnosed with asthma between 1999 and 2013 from the National Health Insurance Research Database in Taiwan...

OBJECTIVE: This study aimed to explore whether saliva pepsin concentration (SPC) could be regarded as a risk factor for the occurrence and unfavorable control of asthma in children with allergic rhinitis. METHODS: A prospective study was conducted on a group of 20 consecutive children newly diagnosed with allergic rhinitis and asthma (referred to as the asthma group). All these children underwent fractional exhaled nitric oxide (FeNO) measurement, lung function tests, and assessment of asthma control using the 7-item Childhood Asthma Control Test (C-ACT) score...

PURPOSE: Bronchial thermoplasty (BT) is a bronchoscopic intervention for the treatment of severe asthma. Despite demonstrated symptomatic benefit, the underlying mechanisms by which this is achieved remain uncertain. We hypothesize that the effects of BT are driven by improvements in ventilation heterogeneity as assessed using functional respiratory imaging (FRI). PATIENT AND METHODS: Eighteen consecutive patients with severe asthma who underwent clinically indicated BT were recruited...

PURPOSE: Only a few studies have focused on the brain mechanisms underlying the itch processing in AD patients, and a neural biomarker has never been studied in AD patients. We aimed to develop a deep learning model-based neural signature which can extract the relevant temporal dynamics, discriminate between AD and healthy control (HC), and between AD patients who responded well to acupuncture treatment and those who did not. PATIENTS AND METHODS: We recruited 41 AD patients (22 male, age mean ± SD: 24...

INTRODUCTION: The San Joaquin Valley (SJV) is often recognized as one of the most polluted regions in the US. Periods of pollution exposure are associated with increased health burden related to respiratory inflammation and undermined lung function, which aggravates respiratory diseases such as asthma and leads to symptoms such as coughing, wheezing, or difficulty breathing. Asthma costs US$ 82 billion annually in healthcare costs, missed work and school in the US. METHODS: Employing a societal perspective, a cost of illness design was combined with environmental epidemiological methods to analyze the economic impact of O3 , NO2 , and PM2...

BACKGROUND: There is an increasing body of evidence associating short-term ambient nitrogen dioxide (NO2 ) exposure with asthma-related hospital admissions in children. However, most studies have relied on temporally resolved exposure information, potentially ignoring the spatial variability of NO2 . We aimed to investigate how daily NO2 estimates from a highly resolved spatio-temporal model are associated with the risk of emergency hospital admission for asthma in children in England...

BACKGROUND: Adverse reactions induced by isoosmolar contrast medium (iodixanol) are mostly mild, with rashes and headaches being the most common. Although anaphylactic shock has been reported, no related incidents have been documented on cerebral angiography. OBJECTIVE: This article reports a serious case of anaphylactic shock possibly induced by iodixanol and provides an overview of the case report. CASE SUMMARY: A 65-year-old female with persistent headaches for nearly six months and CTA examination revealed multiple intracranial aneurysms...

BACKGROUND: Bronchial thermoplasty (BT) improves clinical outcomes and quality of life for patients with severe asthma and has shown sustained reductions in airway narrowing and air trapping in previous CT studies. However, there is a lack of a comprehensive analysis, including CT evaluation, of clinical outcomes in Japanese patients who have undergone BT for severe asthma. This study aimed to evaluate the impact of BT in Japanese asthma patients, with a focus on the CT metric "WA at Pi10" to assess airway disease...

BACKGROUND AND AIMS: It is essential to have proper treatment and management for asthma in order to minimise symptoms, lessen the burden, and lower the chance of exacerbations. To better control asthma, the purpose of this study was to evaluate and enhance paediatric registrars' understanding and application of asthma treatment. METHODS: The Sudan Medical Specialisation Board (SMSB) paediatric registrars provided data for this quasi-interventional study between April and September of 2021...

PURPOSE: Real-world evidence of benralizumab effectiveness on nasal polyps (NP) and asthma outcomes in patients with severe eosinophilic asthma (SEA) and comorbid chronic rhinosinusitis with NP are limited. The objective of this study was to assess NP and asthma outcomes in benralizumab-treated patients with SEA and comorbid NP in a real-world setting. PATIENTS AND METHODS: RANS was a retrospective, multi-country observational study (ClinicalTrials.gov: NCT05180357) using medical chart reviews of adults with SEA and comorbid NP...

Atopic dermatitis (AD) may sometimes be comorbid with alopecia areata (AA). However, traditional treatments for AA show limited efficacy. New treatment options, such as dupilumab and Janus kinase inhibitors, have proven efficacy in addressing both AD and AA. This article highlights the challenging case of a 12-year-old boy experiencing severe refractory AD and comorbid AA treated with oral abrocitinib after dupilumab failure with 1-year follow-up. After 3 months of treatment, his skin manifestations improved and the hair completely regenerated...

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)...
