Severe asthma, characterized by ongoing symptoms and airway inflammation despite high doses of inhaled and/or systemic corticosteroids, is the focus of research efforts to understand this underlying heterogeneity. Clinical phenotypes in both adult and pediatric asthma have been determined using supervised definition-driven classification and unsupervised data-driven clustering methods. Efforts to understand the underlying inflammatory patterns of severe asthma have led to the seminal discovery of type 2-high versus type 2-low phenotypes and to the development of biologics targeted at type 2-high inflammation to reduce the rates of severe asthma exacerbations. Type 2-high asthma is characterized by upregulation of T helper 2 immune pathways including interleukin (IL)-4, IL-5, and IL-13 along with eosinophilic airway inflammation, sometimes allergic sensitization, and responsiveness to treatment with corticosteroids. Type 2-low asthma is poorly responsive to corticosteroids and is not as well characterized as type 2-high asthma. Type 2-low asthma is limited by being defined as the absence of type 2-high inflammatory markers. Choosing a biologic for the treatment of severe asthma involves the evaluation of a panel of biomarkers such as blood eosinophils, total and specific immunoglobulin E/allergic sensitization, and fractional exhaled nitric oxide. In this review, we focus on the underlying pathobiology of adult and pediatric asthma, discuss the different phenotype-based treatment options for adult and pediatric type 2-high with or without allergic asthma and type 2-low asthma, and describe a clinical phenotyping approach to patients to guide out-patient therapy. Finally, we end with a discussion of whether pediatric asthma exacerbations necessitating admission to an ICU constitute their own high-risk phenotype and/or whether it is a part of other previously defined high-risk subgroups such as difficult-to-control asthma, exacerbation-prone asthma, and severe treatment-resistant asthma.</p>","PeriodicalId":21125,"journal":{"name":"Respiratory care","volume":" ","pages":""},"PeriodicalIF":2.4,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143516507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its measurement can be influenced by various factors, which leads to inconsistent optimal thresholds and accuracy. Tissue Doppler imaging variables of the diaphragm have been established as reliable indicators for predicting extubation outcomes. This study aimed to assess the predictive ability of combining diaphragmatic excursion with tissue Doppler imaging variables of the diaphragm in subjects on mechanical ventilation. <b>Methods:</b> This prospective observational study was conducted from April 2023 to April 2024, eligible subjects who underwent mechanical ventilation for > 48 h and successfully completed a 30-min spontaneous breathing test in the ICU of our center. Diaphragmatic excursion and tissue Doppler imaging variables (including peak contraction velocity, peak relaxation velocity, maximal contraction rate, and maximal relaxation rate) were assessed immediately after a 30-min spontaneous breathing trial. The subjects were categorized into successful extubation and failed extubation groups based on their extubation outcomes. Differences in diaphragmatic ultrasound variables between these groups were analyzed. <b>Results:</b> The study included 63 subjects in the successful extubation group and 28 subjects in the failed extubation group. The area under the receiver operating characteristic curve for diaphragmatic excursion in predicting successful extubation was determined as 0.79 (95% CI, 0.69 ∼ 0.89), with a sensitivity of 82.5% and a specificity of 75.0%.

Although degree advancement (DA) opportunities have increased exponentially to support respiratory therapists (RTs) pursue higher levels of education, the number of RTs who pursue a baccalaureate-level degree remain a small percentage of practitioners, indicating that barriers to advancement exist. The purpose of this study was to identify the perceptions and barriers to DA among active RTs. <b>Method:</b> This cross-sectional study utilized a web-based survey to glean descriptive and qualitative information related to the study questions. The survey was conducted using Qualtrics software and released via a social media platform with a specific audience of over 60,000 practicing RTs. <b>Results:</b> Responses from 785 RTs were included in the final analysis.

Other factors such as age and years of experience also play large roles in an individual's choice to return for DA.
