All participants completed the following questionnaires: Numerical rating scale (NRS) breathlessness severity, NRS distress due to breathlessness, NRS self-efficacy for managing breathlessness, Dyspnoea 12, chronic respiratory disease questionnaire (CRQ), brief illness perception questionnaire (brief IPQ) and the cognitive and behavioural response questionnaire short version (CBRQ-S). The associations between the brief IPQ, CBRQ-S, NRS breathlessness severity, distress and self-efficacy, D-12 and CRQ were examined using Spearman's rho correlation coefficients. A Spearman's rho of≥0.50 was pre-defined as the threshold to denote important associations between variables. A p value <0.008 was considered statistically significant, to account for the number of comparisons performed.Illness perception items: consequences, identity, concern, and emotional response were associated with increased breathlessness severity, increased distress, reduced breathlessness self-management ability and lower health related quality of life. Symptom focusing and embarrassment avoidance were identified as important cognitive responses to chronic breathlessness.Interventions that directly target illness perceptions, cognitive and behavioural responses to chronic breathlessness may improve symptom burden, self-efficacy, and health-related quality of life.","PeriodicalId":504874,"journal":{"name":"ERJ Open Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140220975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Combinations of 5 feature-selection and 5 classification methods were evaluated; a training dataset was used for feature-selection and to train the models, and a testing dataset was used for model evaluation.

Chronic obstructive pulmonary disease (COPD) and bronchiectasis are common comorbidities among patients with NTM-PD, and it is challenging to treat NTM-PD in patients with these conditions. There are limited data on the incremental burden that NTM-PD adds to underlying COPD or bronchiectasis in Japan. Therefore, the objective of this study was to assess the incremental burden associated with NTM-PD in patients with pre-existing COPD and/or bronchiectasis.This nested case-control study was based on JMDC, Inc. (JMDC) claims data (2015–2020). Patients with COPD and/or bronchiectasis with NTM-PD (cases) were age and sex matched 1:3 to patients with COPD and/or bronchiectasis without NTM-PD (controls), resulting in 3 mutually exclusive patient groups (COPD, bronchiectasis, or both, with/without NTM-PD). Incremental burden of NTM-PD was assessed within each group by comparing hospitalisations during the 1-year period after NTM-PD diagnosis (index) between cases and controls with both univariate analysis and multivariate analysis adjusting for pre-index comorbidities.Univariate analyses in the 3 patient groups consistently demonstrated incremental hospitalisation burden in casesversuscontrols (eg, COPD group: 20% of 492 casesversus13% of 1476 controls had all-cause hospitalisations; 11%versus5% had respiratory-related hospitalisations; and 6%versus2% had COPD-related hospitalisations). Subsequent multivariate analysis further confirmed the findings.The substantial incremental burden of hospitalisation associated with NTM-PD in patients with COPD and/or bronchiectasis highlights the urgent need for appropriate management of NTM-PD in Japan.","PeriodicalId":504874,"journal":{"name":"ERJ Open Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140242631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this systematic review is to analyse the evidence available to date in relation to pleuropulmonary ultrasound elastography, especially focusing on the three pathologies with the most publications: subpleural consolidations, interstitial lung diseases (ILDs), and pleural effusion. Methods: Originalin vivostudies published up until 12/08/2023 in the Embase, MEDLINE, or Web of Science databases were included. The QUADAS-2 tool was applied to analyse bias. Results:o Included studies: we found 613 records in databases searching. After duplicates removal, we screened 246 records, and finally included 18 papers.o Synthesis of the results: The average cohort sample size was 109 patients. The elastography modes most frequently used were strain (22.2%), transient elastography (TE; 22.2%), point shear-wave elastography (pSWE; 38.9%), and two-dimensional shear-wave elastography (2D-SWE; 22.2%). The possibility of a meta-analysis was ruled out because of the heterogeneity of the studies included. Discussion: The currently available literature indicated that pleuropulmonary ultrasound elastography produced promising and consistent results, although the lack of standardisation in the use of the technique and in the elastography modes employed still impedes its use in daily clinical pneumology practice. The development of a clinical guideline establishing a common nomenclature and standardised techniques for pleuropulmonary elastography will be imperative to generate quality scientific evidence in this field.

The relationship between the adaptive immune dynamics in the lower airways with those in the systemic circulation, and how these relate to an individual's clinical response to SARS-CoV-2 infection, are less understood and are the focus of this study. Here, we investigate the adaptive immune response to SARS-CoV-2 in paired samples from the lower airways and blood from 27 critically ill patients during the first wave of the pandemic (median time from symptom onset to intubation 11 days). Measurements included clinical outcomes (mortality), broncheoalveolar lavage (BAL) and blood specimen antibody levels, and BAL viral load. While there was heterogeneity in the levels of the SARS-CoV-2 specific antibodies, we unexpectedly found that some BAL specimens displayed higher levels than in paired concurrent plasma samples, despite the known dilutional effects common in BAL samples. We found that survivors had higher levels of anti-Spike, anti-Spike-NTD, and anti-Spike-RBD IgG antibodies in their BAL (6684 [258–13 148]versus15 899 [8958–22 629], 5336 [256–10 343]versus13 494 [8028–19 414], and 1620 [199–6637]versus8466 [5144–16 157] median fluorescent intensity units, for deceasedversussurvivors, respectively, p<0.05), while there was no such association with antibody levels in the systemic circulation.
