Background: The Bronchoscopic Lung Volume Reduction (BLVR) is recommended in patients with severe Chronic Obstructive Pulmonary Disease (COPD) who are still symptomatic and have hyperinflation despite having received optimal medical therapy and Pulmonary Rehabilitation (PR). However, the small number of PR centers is insufficient to compensate for the need for existing hospital-based PR programs.
Objective: This article aimed to compare between hospital-based and home-based PR programs in terms of effectiveness on BLVR candidates.
Methods: This study is a prospective, controlled, nonrandomized clinical trial. Stable COPD patients who were referred to our PR clinic prior to BLVR were recruited consecutively. Patients were evaluated in two groups, hospital-based PR (Group 1) or home-based PR (Group 2). Both groups were admitted to the recommended PR for eight weeks. Pulmonary function tests, modified Medical Research Council (mMRC) dyspnea scale, COPD Assessment Test (CAT) and the 6-min walk distance (6MWD) were assessed for each patient before and after PR.
Results: A total of 67 patients were enrolled in the study. The max. age was 79 years and min. age was 49 years, with 65(±7.45) as a mean ±SD. Improvements in the mMRC and CAT scores after PR in both groups were significant and a similar level. Whereas, 6MWD was only significantly increased in Group 1.
Conclusions: This study, demonstrated that both home-based and hospital-based PR provided significant and similar improvements in the mMRC and CAT scores but 6MWD was only significantly increased in the hospital-based PR. Since 6MWD after PR plays a major role in BLVR eligibility, our findings suggest that hospital-based PR may be the most appropriate method for BLVR candidates.

Background: Chronic obstructive pulmonary disease (COPD) affects breathing, speech production, and coughing. We evaluated a machine learning analysis of speech for classifying the disease severity of COPD.
Methods: In this single centre study, non-consecutive COPD patients were prospectively recruited for comparing their speech characteristics during and after an acute COPD exacerbation.
Cumulative Dispensing of Oral Corticosteroids Over 12 Months in People with COPD.
Int J Chron Obstruct Pulmon Dis

Purpose: Oral corticosteroids (OCS) are recommended for the treatment of exacerbations in people with COPD; however, high cumulative lifetime doses (≥1000mg prednisolone-equivalent) are associated with adverse health effects. This issue is well defined in asthma but is less well understood in COPD. The aim of this study was to examine cumulative OCS dispensed to people with COPD over 12 months.

Anti-glomerular basement membrane disease is a rare small vessel vasculitis caused by the deposition of immunoglobulin G (IgG) autoantibodies in the basement membrane of glomerular capillaries and lung alveoli, leading to rapidly progressive renal failure and/or alveolar hemorrhage. We report the case of an 83-year-old female patient presenting with uremic symptoms, rapidly progressive kidney failure, and a high titer of anti-glomerular basement membrane antibodies. Given the urgent need for kidney replacement therapy, the substantial fibrosis and glomerular scarring observed in the kidney biopsy suggesting a chronic process, and the absence of pulmonary involvement, neither immunosuppressive treatment nor plasmapheresis was initiated, since a low likelihood of a favorable response to these interventions was expected.

Purpose: The study aims to identify determinants of implementation behavior among physical therapists frequently promoting physical activity (PA) in cardiac and pulmonary rehabilitation.
Methods: A cross-sectional online survey incorporating the Determinants of Implementation Behavior Questionnaire (DIBQ) and anchored by the Theoretical Domains Framework (TDF) was sent to physical therapists working in cardiac and pulmonary rehabilitation practices in Australia and Singapore. All items on the DIBQ were scored on a 7-point Likert scale from "Strongly Disagree" to "Strongly Agree.

Aim: Regulatory T cells (Tregs) play a crucial role in the development and progression of atherosclerosis. However, the specific association between Treg immune traits and atherosclerosis and related cardiovascular diseases remains unclear, impeding their potential for clinical therapeutic application.
Method: Fifty-eight Treg-related immune traits were obtained from the latest summary level genome-wide association study, which included 3,757 individuals from Sardinia.
