Assessment of fitness to dive in candidates with possible asthma - a pilot study

Conclusion: Using a clinical algorithm with mannitol challenge for assessment of fitness to dive in patients with possible asthma allowing re-challenge testing after stepping-up asthma therapy increased the proportion of individuals classified as fit for recreational SCUBA diving.

CONCLUSION: Tracheal lesions mimic the symptoms of airway obstruction caused by asthma and should be always be part of the differential diagnosis in young patients with no response to asthma treatment. PMID: 32991249 [PubMed - as supplied by publisher]

Spirometry is the most common pulmonary function test (PFT) used to follow asthma patients. It is recommended to withhold short-acting β2-agonists (SABA) a few hours before pulmonary function testing and to withhold long-acting β2-agonists (LABA) for diagnosis purpose but not for the assessment of response to a current treatment [1]. In children with asthma, the addition of LABA to inhaled corticosteroids (ICS) has no clear clinical benefit, but it has proved to improve baseline forced expiratory volume in 1 s (FEV1) [2]. The maximal increase in FEV1 after a single dose of formoterol was measured 3 h af...

on DJ Abstract BACKGROUND: Benralizumab is an IL5-receptor monoclonal antibody licensed for the treatment of severe eosinophilic asthma (SEA). It has demonstrated efficacy in clinical trials in reducing asthma exacerbation rates and maintenance oral corticosteroids (mOCS). RESEARCH QUESTION: Our aim was to evaluate the real-world effectiveness of benralizumab and identify any baseline characteristics associated with response to therapy. STUDY DESIGN: &Methods: We assessed outcomes in all SEA patients commenced on benralizumab at our specialist centre. At each dosing visit, exacerbation history, mOCS ...

Conclusions: In our study, FEV1% and ACT score could predict exacerbations of asthma whereas FeNO could not. FeNO level correlated inversely with ACT score. FeNO level decreased with inhaled corticosteroid usage.

CONCLUSION: Understanding similarities and differences among the recommendations of the various professional bodies will aid in medical decision-making in managing asthma in the COVID-19 pandemic. Health professionals should also consider the individual needs, preferences and values of their patients and the unique characteristics of their local healthcare systems.

Abstract BACKGROUND: Fraction exhaled nitric oxide (FeNO) is a non-invasive biomarker of type-2 asthma that can predict response to inhaled corticosteroid(ICS) therapy. Little is known regarding the magnitude of FeNO reduction following an oral corticosteroid(OCS) course and less is known whether there are differential responses based on race in children with mild-to-moderate asthma. OBJECTIVE: To assess the effect of a short course of OCS on FeNO in asthmatic children and to determine if the effect is influenced by race. METHODS: Children presenting with an acute asthma exacerbation, who had a FeNO meas...

Conclusion: Results suggest that HRV analysis could be useful for the continuous monitoring of ANS anomalies present in asthma, thus contributing to evaluate the evolution of the disease, which is especially challenging in young children. Significance: Noninvasive ANS assessment using HRV analysis could be useful in the continuous monitoring of asthma in children.

Short-acting β2-agonists (SABAs) are inseparable from asthma. The word "Ventolin" has not only entered common language, but it profoundly symbolises relief from breathing distress, quite similar to how "nitroglycerin" supposedly rescues the heart. After the Second World War, synthetic corticosteroids revolutionised asthma management and gained nobility once an inhaled formulation was available [1]. Intriguingly, despite the fact that chronic airway inflammation is inherent to the definition of asthma, as needed SABA was kept in guidelines as the preferred option for the mildest patients, and this u...

n C Abstract The aim of this study was to identify asthma phenotypes through cluster analysis. Cluster analysis was performed using self-reported characteristics from a cohort of 1291 Swedish asthma patients. Disease burden was measured using the Asthma Control Test (ACT), the mini Asthma Quality of Life Questionnaire (mini-AQLQ), exacerbation frequency and asthma severity. Validation was performed in 748 individuals from the same geographical region. Three clusters; early onset predominantly female, adult onset predominantly female and adult onset predominantly male, were identified. Early onset predominantly fem...

kaanranta H Abstract Primary health care (PHC) providers are at the front line of asthma management. To evaluate how planned asthma follow-up occurred in PHC and whether lung function tests were used, 203 patients were followed for 12 years as part of a real-life asthma cohort Seinäjoki Adult Asthma Study (SAAS). A total of 152 patients had visits in PHC attending on average to four planned contacts during 12-year follow-up corresponding to one visit every third year. National guideline recommends annual visits. Patients with ≥4 contacts seemed to have more difficult asthma and better adherence to inhaled ...
