Article Synopsis
  • The study investigates how pre-biologic biomarker levels, specifically immunoglobulin E (IgE), blood eosinophil count (BEC), and fractional exhaled nitric oxide (FeNO), influence asthma treatment outcomes when patients start biologic therapy.
  • Conducted across 23 countries with over 3750 patients, the research focused on changes in exacerbation rates, symptom control, and lung function about a year after starting treatment.
  • Results showed that higher levels of BEC and FeNO were linked to significant improvements in lung function for specific biologic therapies, while IgE was not a strong predictor of treatment effectiveness.

Article Synopsis
  • Previous studies on how comorbidities affect the effectiveness of biologic agents in asthma were limited in size and duration, lacking comparisons between different biologic classes.
  • This cohort study analyzed data from the International Severe Asthma Registry across 21 countries to assess changes in asthma outcomes after starting biologic therapy in patients with type 2-related comorbidities.
  • Results showed that patients with chronic rhinosinusitis (CRS) and nasal polyps (NPs) experienced significantly better outcomes, including fewer exacerbations and improved asthma control, while allergic rhinitis and atopic dermatitis did not influence therapy effectiveness.

Article Synopsis
  • Many severe asthma patients with high oral corticosteroid exposure (HOCS) are eligible for biologic treatments but often do not start them; this study compares those that do and don’t initiate biologics.
  • The study analyzed data from 1,412 patients worldwide between 2015 and 2021, finding that 70.5% initiated a biologic, with differences in patient characteristics influencing this decision, such as higher blood eosinophil counts and more health complications in those who did start treatment.
  • Despite similar rates of asthma exacerbations, one-third of severe HOCS patients did not receive biologics, indicating a gap in treatment that may depend on specific disease features rather than just exacerbation frequency. *

Introduction: International registries provide opportunities to describe use of biologics for treating severe asthma in current clinical practice. Our aims were to describe real-life global patterns of biologic use (continuation, switches, and discontinuations) for severe asthma, elucidate reasons underlying these patterns, and examine associated patient-level factors.

Methods: This was a historical cohort study including adults with severe asthma enrolled into the International Severe Asthma Registry (ISAR; http://isaregistries.

Background: Regulatory bodies have approved five biologics for severe asthma. However, regional differences in accessibility may limit the global potential for personalized medicine.

Objective: To compare global differences in ease of access to biologics.

Background: We developed an eosinophil phenotype gradient algorithm and applied it to a large severe asthma cohort (International Severe Asthma Registry).

Objective: We sought to reapply this algorithm in a UK primary care asthma cohort, quantify the eosinophilic phenotype, and assess the relationship between the likelihood of an eosinophilic phenotype and asthma severity/health care resource use (HCRU).

Methods: Patients age 13 years and older with active asthma and blood eosinophil count or 1 or greater, who were included from the Optimum Patient Care Research Database and the Clinical Practice Research Datalink, were categorized according to the likelihood of eosinophilic phenotype using the International Severe Asthma Registry gradient eosinophilic algorithm.

Background: Phenotypic characteristics of patients with eosinophilic and noneosinophilic asthma are not well characterized in global, real-life severe asthma cohorts.

Research Question: What is the prevalence of eosinophilic and noneosinophilic phenotypes in the population with severe asthma, and can these phenotypes be differentiated by clinical and biomarker variables?

Study Design And Methods: This was an historical registry study. Adult patients with severe asthma and available blood eosinophil count (BEC) from 11 countries enrolled in the International Severe Asthma Registry (January 1, 2015-September 30, 2019) were categorized according to likelihood of eosinophilic phenotype using a predefined gradient eosinophilic algorithm based on highest BEC, long-term oral corticosteroid use, elevated fractional exhaled nitric oxide, nasal polyps, and adult-onset asthma.

Background: Allergy, eosinophilic inflammation, and epithelial dysregulation are implicated in severe asthma pathogenesis.

Objective: We characterized biomarker expression in adults with severe asthma.

Methods: Within the International Severe Asthma Registry (ISAR), we analyzed data from 10 countries in North America, Europe, and Asia, with prespecified thresholds for biomarker positivity (serum IgE ≥ 75 kU/L, blood eosinophils ≥ 300 cells/μL, and FeNO ≥ 25 ppb), and with hierarchical cluster analysis using biomarkers as continuous variables.

Background: MP-AzeFlu (Dymista®; spray of azelastine/fluticasone propionate) is the most effective allergic rhinitis (AR) treatment available. Its effect on asthma outcomes in patients with AR and asthma is unknown.

Methods: This pre-post historical cohort study, using the Optimum Patient Care Research Database, included patients aged ≥12 years, from UK general practice with active asthma (defined as a recorded diagnosis, with ≥1 prescription for reliever or controller inhaler) in the year before or at the initiation date.

Article Synopsis
  • Severe asthma is often missed in primary care; this study aimed to identify potential severe asthma (PSA) cases in UK primary care and compare them with patients confirmed as having severe asthma in tertiary care.
  • Among 207,557 asthma patients, 16,409 (8%) were identified with PSA, yet 72% had not been referred to specialists in the past year.
  • Referred PSA patients showed worse asthma control and higher exacerbation rates compared to non-referred patients, while confirmed severe asthma patients were younger and had even more severe symptoms and complications.

Background: Severe asthma exerts a disproportionately heavy burden on patients and health care. Due to the heterogeneity of the severe asthma population, many patients need to be evaluated to understand the clinical features and outcomes of severe asthma in order to facilitate personalised and targeted care. The International Severe Asthma Registry (ISAR) is a multi-country registry project initiated to aid in this endeavour.

Background: Clinical characteristics of the international population with severe asthma are unknown. Intercountry comparisons are hindered by variable data collection within regional and national severe asthma registries. We aimed to describe demographic and clinical characteristics of patients treated in severe asthma services in the United States, Europe, and the Asia-Pacific region.

Background: Allergic rhinitis (AR) management has changed in recent years following the switch from the concept of disease severity to the concept of disease control, publication of the AR clinical decision support system (CDSS) and development of mobile health (m-health) tools for patients (eg Allergy Diary). The Allergy Diary Companion app for healthcare providers is currently being developed and will be launched in 2018. It incorporates the AR CDSS to provide evidence-based treatment recommendations, linking all key stakeholders in AR management.

Psychiatric nurses or therapists may be subpoenaed to appear as direct or expert witnesses. The response must be carefully prepared, and nurses must be aware that testifying in court can be an anxiety-provoking experience. Testifying often involves being an advocate for a client.

This report describes and evaluates the current status of outcome analysis in Psychiatric Consultation-Liaison Nursing (PCLN) and offers suggestions for future development. The status of outcome evaluation generally in psychiatric nursing is described with attention given to the scope of practice of PCLN and outcomes used by psychiatric consultation-liaison nurses (PCLNs) to evaluate their interventions. An evaluation framework based on Donabedian's paradigm of structure, process, and outcome is presented and its applicability shown to PCLN.

My recommendations are to learn about the mentoring process, prepare for the role, and take advantage of the opportunity to mentor someone, or many people, throughout your professional lifetime. In the process, you will learn about your cognitive, affective, and behavioral competencies and gifts. Share them.
