OBJECTIVE: As an art form, drawings can facilitate the tangible expression of patients' inner images and feelings in a range of health conditions. However, there are currently no published studies investigating adults' perspectives of asthma using drawings. This study aimed to explore how adults' drawings illustrate their perceptions and experiences of asthma. METHODS: Adults with asthma participated in a one-on-one drawing activity. Analysis was grounded in the participants' accounts of their drawing, which were examined alongside the relevant image...

OBJECTIVE: Studies show high comorbidity of mood disorders in asthma. As asthma is a highly heterogeneous disease with different phenotypes it can be expected that there is a difference in this association with different asthma phenotypes. The aim of our cross-sectional study was to assess the association of specific asthma phenotypes with anxiety and/or depression and their impact on asthma control. METHODS: A cross-sectional study in 201 consecutive adult outpatients with asthma (≥18 years of age) was conducted...

INTRODUCTION: Given the known link between asthma and stress as well as the link between mindfulness and stress, we explore the possible association between trait mindfulness and asthma-related diagnosis and symptoms with a cross-sectional study. METHOD: In 2014, we surveyed a sample of college students in their freshman year, from a public university in Shanghai, China. We used three multilevel logistic regressions to estimate the association between trait mindfulness (measured by Mindful Awareness Attention Scale, MAAS) and self-report of ever having an asthma diagnosis, ever having had persistent dry cough, and ever having had wheezing symptoms...

We hypothesize that oxidative stress induced by trichloramine exposure during swimming could be related to etiopathogenesis of asthma among elite swimmers. AIM: To investigate the effect of a swimming training session on oxidative stress markers of asthmatic compared to non-asthmatic elite swimmers using exhaled breath (EB) metabolomics. METHODS: Elite swimmers annually screened in our department (n=27) were invited and those who agreed to participate (n=20, of which 9 with asthma) had EB collected (Tedlar(®) bags) before and after a swimming training session...

The number of genetic factors associated with asthma remains limited. To identify new genes with an undetected individual effect but collectively influencing asthma risk, we conducted a network-assisted analysis that integrates outcomes of genome-wide association studies (GWAS) and protein-protein interaction networks. We used two GWAS datasets, each consisting of the results of a meta-analysis of nine childhood-onset asthma GWASs (5,924 and 6,043 subjects, respectively). We developed a novel method to compute gene-level P-values (fastCGP), and proposed a parallel dense-module search and cross-selection strategy to identify an asthma-associated gene module...

BACKGROUND: Adolescents with asthma are at high risk of poor adherence with treatment. This may be compounded by activities that worsen asthma, in particular smoking. Additional support above and beyond routine care has the potential to encourage good self-management. We wanted to find out whether sessions led by their peers or by lay leaders help to reduce these risks and improve asthma outcomes among adolescents. OBJECTIVES: To assess the safety and efficacy of lay-led and peer support interventions for adolescents with asthma...

BACKGROUND: Despite its proven efficacy in improving symptoms and reducing exacerbations, many patients with asthma are not fully adherent to their steroid inhaler. Suboptimal adherence leads to poorer clinical outcomes and increased health service utilisation, and has been identified as a contributing factor to a third of asthma deaths in the UK. Reasons for non-adherence vary, and a variety of interventions have been proposed to help people improve treatment adherence. OBJECTIVES: To assess the efficacy and safety of interventions intended to improve adherence to inhaled corticosteroids among people with asthma...

BACKGROUND: Teachers and school staff should be competent in managing asthma in schools. Demonstrated low levels of asthma knowledge mean that staff may not know how best to protect a child with asthma in their care, or may fail to take appropriate action in the event of a serious attack. Education about asthma could help to improve this knowledge and lead to better asthma outcomes for children. OBJECTIVES: To assess the effectiveness and safety of asthma education programmes for school staff, and to identify content and attributes underpinning them...

Background: HASH(0x312e250) Pancreatic ductal adenocarcinoma (PDAC) is usually diagnosed in late adulthood; therefore, many patients suffer or have suffered from other diseases. Identifying disease-patterns associated with PDAC risk may enable a better characterization of high-risk patients. Methods: HASH(0x314a720) Multimorbidity patterns (MPs) were assessed from 17 self-reported conditions using hierarchical clustering, principal component, and factor analyses in 1705 PDAC cases and 1084 controls from a European population...

BACKGROUND: Assessment of sensitization at an isolated time-point during childhood provides limited clinical information. We hypothesized that sensitization develops as specific patterns with respect to age at debut, development over time, and involved allergens, and that such patterns might be more biologically and clinically relevant. OBJECTIVE: To explore latent patterns of sensitization during the first 6 years of life and investigate whether such patterns associate to development of asthma, rhinitis, and eczema...

BACKGROUND: Several observational studies have suggested that outdoor air pollution may induce or aggravate asthma. However, epidemiological results are inconclusive due to the presence of numerous moderators which influence this association. The goal of this study was to assess the relationship between outdoor air pollutants and moderate or severe asthma exacerbations in children and adults through a systematic review and multilevel meta-analysis. MATERIAL AND METHODS: We searched studies published in English on PubMed, Scopus, and Google Scholar between January 2000 and October 2016...

BACKGROUND: Bronchial asthma is a heterogeneous disease characterized by three cardinal features: chronic inflammation, variable airflow obstruction, and airway hyperresponsiveness. Asthma has traditionally been defined using nonspecific clinical and physiologic variables that encompass multiple phenotypes and are treated with nonspecific anti-inflammatory therapies. Based on the modulation of airway remodeling after 12 months of anti-immunoglobulin E (IgE) treatment, we identified two phenotypes (omalizumab responder, OR; and non-omalizumab responder, NOR) and performed morphometric analysis of bronchial biopsy specimens...

REVIEW
Rebecca Normansell, Kayleigh M Kew, Alexander G Mathioudakis
BACKGROUND: Asthma is a common chronic disease worldwide. Inhalers are often prescribed to help control asthma symptoms, improve quality of life and reduce the risk of exacerbations or flare-ups. However, evidence suggests that many people with asthma do not use their inhaler correctly. It is therefore important to evaluate whether interventions aimed specifically at improving technique are effective and safe, and whether use of these interventions translates into improved clinical outcomes...
