ABSTRACT
BACKGROUND: Dyspnea is considered a silent threat to people diagnosed with Parkinson's disease and may be a common concern in patients, however, little is known about how it affects quality of life. This study explored the experiences of independently mobile people who are affected by dyspnea in daily life. METHODOLOGY: This was a cross-sectional mixed methods study that included an online questionnaire and semi-structured interviews. The participants were included if they were diagnosed with Parkinson's disease; had a self-reported Hoehn and Yahr Score I, II or III; were mobilizing independently; and were Arabic speakers. Participants were excluded if they had any other musculoskeletal, cardiac, respiratory, or neurological diseases; or were previous or current smokers; or had been previously hospitalized due to respiratory complications. RESULTS: A total of 117 participants completed the Arabic version of the Dyspnea-12 Questionnaire. Dyspnea was reported in all participants and that it had an adverse effect on their quality of life, especially during activities of daily living. Additionally, participants reported a lack of knowledge about pulmonary rehabilitation and were unaware of the availability and potential benefits of participation in programs. CONCLUSION: Dyspnea was reported in people in the early stages (Hoehn and Yahr Stages I, II, and III) of Parkinson's disease, and may benefit from routine assessment of lung function, dyspnea management and participation in pulmonary rehabilitation.

OBJECTIVES: Electrocardiogram (ECG) and measurement of plasma brain natriuretic peptides (BNP) are established markers of right ventricular dysfunction (RVD) in the setting of acute pulmonary embolism (PE) but their value at long-term follow-up is largely unknown. The purpose of this prospective study was to determine the prevalence of ECG abnormalities, describe levels of N-terminal proBNP (NT-proBNP), and establish their association with dyspnea at long-term follow-up after PE. DESIGN: All Swedish patients diagnosed with acute PE in 2005 (n = 5793) were identified through the Swedish National Patient Registry. Surviving patients in 2007 (n = 3510) were invited to participate. Of these, 2105 subjects responded to a questionnaire about dyspnea and comorbidities. Subjects with dyspnea or risk factors for development of chronic thromboembolic pulmonary hypertension were included in the study in a secondary step, which involved collection of blood samples and ECG registration. RESULTS: Altogether 49.3% had a completely normal ECG. The remaining participants had a variety of abnormalities, 7.2% had atrial fibrillation/flutter (AF). ECG with any sign of RVD was found in 7.2% of subjects. Right bundle branch block was the most common RVD sign with a prevalence of 6.4%. An abnormal ECG was associated with dyspnea. AF was associated with dyspnea, whereas ECG signs of RVD were not. 61.2% of subjects had NT-proBNP levels above clinical cut-off (>125 ng/L). The degree of dyspnea did not associate independently with NT-proBNP levels. CONCLUSIONS: We conclude that the value of ECG and NT-proBNP in long term follow-up after PE lies mostly in differential diagnostics.

CASE PRESENTATION: A 30-year-old White woman with presumed rheumatoid arthritis accompanied by CT scan evidence of eosinophilic pneumonitis was referred to the ED by her rheumatologist for an investigation of the progression of dyspnea. Approximately 6 months before, the patient reported experiencing diffuse interphalangeal arthralgias (both proximal and distal) that affected the wrists, knees, and feet. These symptoms were accompanied by Modified Medical Research Council scale grade 2 dyspnea. During the initial assessment, the patient exhibited slight pallor and had no indications of inflammatory activity in the joints. Furthermore, the cardiovascular physical examination and the auto-antibody laboratory profile yielded normal results. However, a wrist ultrasound scan revealed evidence of active synovitis; a chest CT scan displayed multifocal bilateral ground-glass opacities and mild thickening of the interlobular septa. These findings suggested the presence of eosinophilic disease or an acute interstitial process related to collagen vascular disease. Consequently, the patient's treatment commenced with a weekly dose of methotrexate (10 mg). Despite the intervention, 2 months later, the patient returned, reporting persistent arthralgia and a worsening of dyspnea, now classified as Modified Medical Research Council scale grade 3. Subsequently, the rheumatologist referred her to the ED for further assessment. During the initial emergency evaluation, the patient experienced a syncope episode accompanied by orthostatic prodromal symptoms that included dizziness, nausea, and malaise.

OBJECTIVES: To develop a statistical approach that provides a quantitative index measuring the magnitude of the irregularity of the breathing response to exercise for the diagnosis of dysfunctional breathing. DESIGN: Cross-sectional, retrospective, real-world study. SETTING: Single-centre study. PARTICIPANTS: A population of 209 patients investigated with cardiopulmonary exercise testing in our institution for unexplained or disproportionate exertional dyspnoea between January and July 2022. PRIMARY AND SECONDARY OUTCOME MEASURES: A novel statistical approach providing a quantitative index-proportional tidal volume variation (PTVV)-was developed to measure the magnitude of the irregularity of the breathing response to exercise. RESULTS: PTVV provided a reliable statistical readout for the objective assessment of DB with a prediction accuracy of 78% (95% CI: 72 to 83%). The prevalence of DB in the investigated population was high with more than half of the patients affected by moderate-to-severe DB. CONCLUSIONS: PTVV can easily be implemented in the clinical routine. Our study suggests a possible further simplification for the diagnosis of DB with two objective criteria including PTVV and one single criterion for hyperventilation.

BACKGROUND: COVID patients continue to experience unremitting symptoms that extend far beyond the initial illness. While there is rapid accumulation of data on acute COVID treatment in hospitalized patients, little is known regarding post-COVID management. OBJECTIVES: To describe our center's experience treating post-COVID sub-syndromes encountered in Post-COVID Lung Clinic. METHODS: We retrospectively reviewed data on 98 post-COVID patients evaluated in our clinic between 07/01/2020-12/31/2022. We encountered three distinct post-COVID subtypes: 1) respiratory complaints associated with increased O2 requirements and abnormal CT findings (post-COVID interstitial lung disease [ILD]), 2) respiratory complaints associated with tachycardia (post-COVID dyspnea-tachycardia syndrome [DTS]). Post-COVID ILD patients (n = 28) received steroids in combination with cell cycle inhibitor (mycophenolate mofetil-MMF). Post-COVID DTS patients (n = 16) were treated with metoprolol. 3) A third, undifferentiated group presented with mild respiratory complaints and normal spirometry (n = 17) and was followed in clinic without initiation of a specific treatment. RESULTS: In treated post-COVID ILD patients, mean oxygen requirements at rest (1.96 ± 1.79 L/NC) decreased to 0.89 ± 1.29 L/NC at 6 months follow-up, p = 0.005. In patients with post-COVID DTS, mean heart rate at rest decreased (98 ± 15 bpm to 79 ± 11 bpm) at 6 months follow-up, p = 0.023. 60 % of patients reported an improvement in exertional dyspnea. CONCLUSIONS: Our descriptive study presents a single center outpatient COVID-19 clinic experience. We encountered 3 post-COVID sub-syndromes and describe their treatments: post-COVID interstitial lung disease [ILD] treated with a novel regimen of MMF and steroids, post COVID dyspnea-tachycardia syndrome [DTS] treated with metoprolol, and a third subgroup with mild undifferentiated symptoms without specific treatment.

In patients with cardiovascular, pulmonary, muscular and neurological diseases, cardiopulmonary exercise testing (CPET) is a valuable tool providing clinically-relevant diagnostic and prognostic information by evaluation of exercise response. CPET requires to be performed in dedicated centers able to correctly carry out the examination and to carefully evaluate the results. CPET analyzes functional capacity revealing both symptomatic and asymptomatic intolerance to exercise. One of the most important advantages for clinicians derived by the use of CPET, beyond standard exercise electrocardiography testing, is the capability not only to grade the severity of the disease, but also to distinguish between different causes of dyspnea and exercise impairment. Indications for CPET use in clinical practice are increasing in the last decades, evolving beyond the routine use as a training tool in athletes. In fact, CPET represents an important step in the management of patients with heart failure or pulmonary hypertension, as suggested by international guidelines. CPET role in helping for the selection of patients candidate to heart transplantation is also well known. Beyond its clinical usefulness, scientific interest in CPET is constantly expanding, mainly due to the safety of the exam and to the huge size of the pathophysiological information that it offers. The aim of this paper is to simply explain everyday applications and potential further purposes of CPET in clinical practice. Our review is intended both for physicians approaching CPET for the first time and for clinicians with an interest in expanding their knowledge in this field.

AbstractMorning Report is a time-honored tradition where physicians-in-training present cases to their colleagues and clinical experts to collaboratively examine an interesting patient presentation. The Morning Report section seeks to carry on this tradition by presenting a patient's chief concern and story, inviting the reader to develop a differential diagnosis and discover the diagnosis alongside the authors of the case.This report examines the story of a 73-year-old man who sought evaluation for 1 month of shortness of breath, bilateral lower-extremity edema, and weight gain of 14 kg. Using questions, physical examination, and testing, an illness script for the presentation emerges. As the clinical course progresses, the differential is refined until a diagnosis is made.

BACKGROUND: Limited research has investigated the relationship between small airway dysfunction (SAD) and static lung hyperinflation (SLH) in patients with post-acute sequelae of COVID-19 (PASC) especially dyspnea and fatigue. METHODS: 64 patients with PASC were enrolled between July 2020 and December 2022 in a prospective observational cohort. Pulmonary function tests, impulse oscillometry (IOS), and symptom questionnaires were performed two, five and eight months after acute infection. Multivariable logistic regression models were used to test the association between SLH and patient-reported outcomes. RESULTS: SLH prevalence was 53.1% (34/64), irrespective of COVID-19 severity. IOS parameters and circulating CD4/CD8 T-cell ratio were significantly correlated with residual volume to total lung capacity ratio (RV/TLC). Serum CD8 + T cell count was negatively correlated with forced expiratory volume in the first second (FEV1) and forced vital capacity (FVC) with statistical significance. Of the patients who had SLH at baseline, 57% continued to have persistent SLH after eight months of recovery, with these patients tending to be older and having dyspnea and fatigue. Post-COVID dyspnea was significantly associated with SLH and IOS parameters R5-R20, and AX with adjusted odds ratios 12.4, 12.8 and 7.6 respectively. SLH was also significantly associated with fatigue. CONCLUSION: SAD and a decreased serum CD4/CD8 ratio were associated with SLH in patients with PASC. SLH may persist after recovery from infection in a substantial proportion of patients. SAD and dysregulated T-cell immune response correlated with SLH may contribute to the development of dyspnea and fatigue in patients with PASC.

BACKGROUND: Dyspnea impairs quality of life (QOL) in patients with fibrotic hypersensitivity pneumonitis (FHP). The Living with Pulmonary Fibrosis questionnaire (L-PF) assesses symptoms, their impacts and PF-related QOL in patients with any form of PF. Its scores have not undergone validation analyses in an FHP cohort. METHODS: We used data from the Pirfenidone in FHP trial to examine reliability, validity and responsiveness of the L-PF-35 Dyspnea domain score (Dyspnea) and to estimate its meaningful within-patient change (MWPC) threshold for worsening. Lack of suitable anchors precluded conducting analyses for other L-PF-35 scores. RESULTS: At baseline, Dyspnea's internal consistency (Cronbach's coefficient alpha) was 0.85; there were significant correlations with all four anchors (University of California San Diego Shortness of Breath Questionnaire scores r = 0.81, St. George's Activity domain score r = 0.82, percent predicted forced vital capacity r = 0.37, and percent predicted diffusing capacity of the lung for carbon monoxide r = 0.37). Dyspnea was significantly different between anchor subgroups (e.g., lowest percent predicted forced vital capacity (FVC%) vs. highest, 33.5 ± 18.5 vs. 11.1 ± 9.8, p = 0.01). There were significant correlations between changes in Dyspnea and changes in anchor scores at all trial time points. Longitudinal models further confirmed responsiveness. The MWPC threshold estimate for worsening was 6.6 points (range 5-8). CONCLUSION: The L-PF-35 Dyspnea domain appears to possess acceptable psychometric properties for assessing dyspnea in patients with FHP. Because instrument validation is never accomplished with one study, additional research is needed to build on the foundation these analyses provide. TRIAL REGISTRATION: The data for the analyses presented in this manuscript were generated in a trial registered on ClinicalTrials.gov; the identifier was NCT02958917.
