Pulmonary Rehabilitation Frequency in COPD Patients

Chronic obstructive pulmonary disease (COPD) is a common condition that can cause breathlessness and reduced physical capacity. Pulmonary rehabilitation (PR) is an effective treatment, but traditional programs often require patients to attend sessions several times per week, which may limit participation. This study aims to compare the effectiveness of two supervised pulmonary rehabilitation programs: one performed 3 days per week and another performed 1 day per week, both over an 8-week period and including additional home-based exercises. The main objective is to determine whether the lower-frequency program is not inferior to the higher-frequency program in improving functional capacity, measured by the six-minute walk test. Secondary outcomes include dyspnea, quality of life, muscle strength, physical activity, adherence, exacerbations, and safety. The results of this study may help optimize pulmonary rehabilitation programs and improve accessibility for patients with COPD.

Why is this study being done? Chronic Obstructive Pulmonary Disease (COPD) causes airflow blockage creating breathing issues, distress, and lower well-being. COPD also causes hyperinflation of the lungs. The investigators are doing the study to learn more about improving lung function for patients with COPD by using voice-based experiences. What is being tested in this study? If singing/vocalizing can improve lung function. How long will I be in the study? The study will last 4 weeks and involve 2 in-person visits to KUMC with virtual vocal sessions two times a week over Zoom.

COPD Exacerbation Follow Up

The goal of this study is to evaluate the impact of implementing an AI-enabled clinical workflow tool (Viz COPD) on respiratory specialist follow up and clinical outcomes after an acute exacerbation.

A Study to Understand the Accuracy of a New Breathing Device Compared to Standard Testing for Asthma and COPD

The diagnosis of either asthma or chronic obstructive pulmonary disease (COPD) is currently based on a combination of symptoms, different lung tests and sometimes a 'trial by treatment'. Both COPD and Asthma tests currently include forced breathing using a test known as spirometry which can be difficult and uncomfortable for people to perform and needs expert interpretation. Asthma can require multiple tests in sequence which can make the process of diagnosis long and inconvenient for patients. In the UK, there have been challenges providing enough testing for COPD and asthma, in part because the tests are challenging to provide in the community to everyone who needs one. The STARDUST study aims to test and develop new ways of diagnosing asthma and COPD that are quick, accurate and easy for patient and healthcare professionals to perform. People who have been referred for routine lung testing will breathe normally in and out into a handheld device called the N-Tidal Handset for 75 seconds. This device measures how the level of carbon dioxide (CO2) changes in the breath as people breath through it. The information gathered on the N-Tidal Handsets, called breath records or capnograms, will not be used to alter the diagnosis of any participants in the study. After the capnograms have been collected, the research team will test 'algorithms' that have been developed using artificial intelligence, to see if they can accurately identify the correct diagnosis. Information collected in the study will also be used to make improvements in these algorithms. If confirmed to be accurate, these algorithms could be used in clinical practice to help healthcare professionals make faster, more accessible and accurate diagnoses, especially in settings like GP clinics in the community where access to specialist tests may be limited.

Probiotics in COPD: Effects on Symptoms, Lung Function, and Inflammation

The goal of this randomized, placebo controlled, double-blind clinical trial is to find out whether a probiotic supplement can help adults with chronic obstructive pulmonary disease (COPD) breathe better and better control their symptoms. The study will try to answer does taking a probiotic supplement, compare with a placebo, reduce shortness of breath, does it improve daily COPD symptoms or change stool patterns by using validated questionnaires; does it affect lung function or inflammation. The results of this study may contribute to a better understanding of the disease, the application of new therapeutic options, and provide a foundation for future research.

Comparative Efficacy of Once-daily LAMA/LABA Combinations Versus Tiotropium on Constant-work-rate Cycle Endurance in COPD

This study is designed to directly compare the effects of widely available long-acting bronchodilator therapies in patients with chronic obstructive pulmonary disease (COPD). The trial evaluates three fixed-dose combinations of a long-acting beta-2 agonist and a long-acting muscarinic antagonist (LABA/uLAMA)-umeclidinium/vilanterol (Anoro® Ellipta), indacaterol/glycopyrronium (Ultibro® Breezhaler), and tiotropium/olodaterol (Spiolto® Respimat)-against tiotropium (Spiriva®), a long-acting muscarinic antagonist (LAMA) used as monotherapy. The primary aim is to assess their impact on exercise capacity, with additional evaluation of pharmacoeconomic outcomes. The study follows a prospective, randomized, open-label, four-period crossover design. Approximately 100 patients with stable COPD will be enrolled from the 2nd Department of Pulmonology and Tuberculosis, Medical University of Białystok, and the University Hospital Pulmonology Outpatient Clinic. Each treatment will last 28 days, separated by a 7-day wash-out period, so that every participant will receive each therapy. Assessments will include standard clinical examinations, lung function testing (spirometry, body plethysmography, DLCO, multiple-breath washout), cardiopulmonary exercise testing (CPET) on a cycle ergometer, the 6-minute walk test, validated questionnaires (SGRQ, CAT, mMRC, BODE index), laboratory tests, and imaging. These procedures are part of routine COPD evaluation and will allow detailed monitoring of respiratory function, exercise tolerance, and quality of life. The study aims to determine whether dual bronchodilation with LABA/uLAMA combinations provides superior improvements in exercise performance and overall efficiency compared to tiotropium alone. Results may help guide clinical decision-making and optimize cost-effectiveness in COPD management.

Real-World Effectiveness of a Triple Combination BDP/FF/GB Extrafine in a Single Pressurised Metered Dose Inhaler in Brazilian COPD Patients

This multicenter, retrospective-prospective, cohort study aims to evaluate the effectiveness and safety of Extra-fine Beclometasone Diproprionate/Formoterol Fumarate/Glycopyrronium Bromide (EF-BDP/FF/GB) therapy in adults with severe or very severe COPD in Brazil. Around 400 patients will be enrolled across approximately 15 sites. Eligible patients must have started treatment on the day of enrollment or up to three months before enrollment. Data will be collected both retrospectively and prospectively, with baseline information covering up to 12 months before treatment initiation. All assessments will occur during routine medical visits, with follow-up expected at approximately 3 ± 1 month and 6 months ± 2 months. The medication Trimbow® will not be provided as part of the study and must be prescribed and used according to the institution's standard clinical practice, regardless of participation in the study.

End-Inspiratory Pause in COPD Patients During Controlled Ventilation

In patients with airflow obstruction receiving mechanical ventilation, an important objective is to reduce lung hyperinflation often using controlled hypoventilation. At the same time, maintaining acceptable gas exchange is challenging, as major reductions in minute ventilation (VE) raises carbon dioxide (CO2) and causes respiratory acidosis, which may lead to adverse physiological consequences. Relatively prolonged end-inspiratory pause (EIP) has been shown to optimize CO2 clearance in hypoxemic mechanically ventilated patients. Previous data suggests that, at equivalent total inspiratory-time (TI), shorter insufflations followed by EIP can enhance CO2 elimination in acute lung injury. Adding EIP is classically discouraged in chronic obstructive pulmonary disease (COPD) because - at constant respiratory rate (RR) - prolonging inspiration reduces expiratory time (TE), and can worsen hyperinflation and impair hemodynamics. In this study, we assessed whether a breathing pattern characterized by high inspiratory flow (V ̇) plus EIP could reduce PaCO2 without inducing hyperinflation, compared with same inspiration-to-expiration time (I:E) and a ventilation pattern without EIP in patients with COPD undergoing controlled hypoventilation. Methods We performed a prospective, single-center, cross-over, randomized trial (ethical approval #10/2024) including deeply sedated and intubated adults with COPD exacerbation, PaCO2 ≥ 45 mmHg and no signs of respiratory effort. Persistent air-leaks, severe hemodynamic instability, pregnancy or intracranial hypertension were exclusion criteria. Patient's next of kin signed the informed consent. At inclusion, we collected demographic characteristics and baseline respiratory variables. A CT-emphysema score, using computed tomographies obtained within 24 hs of intubation for clinical reasons, was calculated (A.R, a pulmonologist specialized in medical imaging). Each lung was divided into 3 regions (superior, medium and inferior) based on anatomical references and were graded as no emphysema (score 0), emphysema ≤25% (score 1), ≤50% (score 2), ≤75% (score 3) and \>75% (score 4). Scores of the six regions were summed to obtain the total score, giving a minimum 0 and a maximum of 24 points. Total scores ≥ 2 are indicative of emphysema. Patients were ventilated in volume-controlled mode with square-flow waveform, tidal volume of predicted body weight (VtPBW) 6-8 ml/kg, TI 0.6-0.8 seconds, RR 10-16 breaths per minute (bpm) and I:E relationship 1:4-1:8. External positive end-expiratory pressure (PEEPext) was set to the maximum value that did not increase plateau pressure (Pplat) ≥ 1cmH2O compared to zero PEEP, and FiO2 to maintain oxygen saturation of 90-95%. Two ventilation strategies, each one applied for 30 minutes, were randomly evaluated: a) ventilation without EIP, using initial ventilator settings (VentNO-PAUSE); b) ventilation with EIP (VentPAUSE), in which V ̇ was increased and 40-50% of the total inspiratory time (TI) was replaced by EIP; the remaining setting were equal to VentNO-PAUSE. At the end of each phase, we collected arterial blood gases, respiratory mechanics and basic hemodynamics. Total PEEP (i.e., PEEPtot=PEEPext + autoPEEP) and Pplat were assessed with 5-second end-expiratory, and 2-second end-inspiratory occlusions, respectively. Driving airway pressure (ΔP) was computed as Pplat - PEEPtot, normalized elastance (ERS-n) as driving pressure (ΔP)/VtPBW and inspiratory airway resistance (Raw) as (Peak pressure \[Ppeak\] - Pplat) / V ̇. We hypothesized that ventilation efficiency would be better during VentPAUSE, and wanted to evaluate whether this strategy would have allowed to reduce VE while keeping the same CO2 obtained without EIP. Accordingly, and assuming a constant CO2 production, we calculated the predicted VE during VentPAUSE to maintain the same CO2 measured during VentNO-PAUSE with the formula : Predicted VE\_( (Vent\_PAUSE))=█(〖PaCO\_(2 )〗\_((Vent\_PAUSE ) ) )/〖PaCO\_2〗\_((Vent\_(NO-PAUSE) ) ) × VE used during the study phases. This allowed to calculate to what extent it would have been possible to reduce VE (VEpred) and RR (RRpred) using the experimental strategy. We additionally calculated the predicted prolongation of expiration using the new RRpred as: TE-pred = (60/RRpred) - TI. We calculated the ventilatory ratio as an indice reflecting physiological dead-space ventilation (VD/VT).

Risk Factors, Costs, and Impacts of ED Boarding

Using Multiomics to Define Mechanisms of Rhinovirus-induced Chronic Obstructive Pulmonary Disease Exacerbations to Develop Novel Therapies and Therapeutic Targets

The goal of this study is to examine exacerbations of chronic obstructive pulmonary disease (COPD) caused by a common cold virus called rhinovirus, to identify new treatments. Exacerbations are flare-ups of respiratory symptoms which are a major cause of ill health in people with COPD, and are most commonly caused by viruses. The main questions the study aims to answer are: * What processes in the body occur in response to rhinovirus infection, and do the differences between people with COPD and healthy volunteers explain why people with COPD develop more severe illness and exacerbations? * Can treatments be identified that target these processes to reduce the severity and frequency of exacerbations in people with COPD? The study will compare eligible participants with COPD to healthy volunteers, and will involve intentionally infecting each participant with rhinovirus in a controlled environment. They will undergo baseline investigations prior to infection including a first bronchoscopy. Post-infection each participant will undergo a range of tests, including a second bronchoscopy, to compare how processes in the body, and especially the lungs, differ between people who do and do not have COPD.

Respiratory Exercises in Frail Elderly COPD Patients

Purpose: This study evaluated the impact of a structured intervention on frailty, lung function, physical capacity, and dyspnea in elderly COPD patients. COPD, common in older adults, often coexists with frailty, which worsens health outcomes. While pulmonary rehabilitation improves function, its effect on frailty remains unclear. Procedures: A total of 66 patients with a confirmed diagnosis of COPD were randomly allocated into two equal groups: an intervention group (n=33) and a control group (n=33). Participants in the intervention group completed a six-week pulmonary rehabilitation program. Both baseline and post-intervention evaluations comprised spirometric measurements (FVC, FEV1, FEV1/FVC ratio, FEF25-75, and PEF), the Edmonton Frailty Scale (EFS), the six-minute walk test (6MWT), oxygen saturation levels, and assessments of dyspnea severity. Results: Significant improvements were observed in the intervention group in FVC, FEV1, FEV1/FVC, and PEF (p\<0.05). Total EFS scores and subdimensions such as mood, general health, and cognitive status also improved significantly (p\<0.05). Additionally, the intervention group showed increased 6MWT distance, higher oxygen saturation, and reduced dyspnea scores post-intervention (p\<0.05), with minimal changes in the control group. Conclusion: The findings suggest that pulmonary rehabilitation not only enhances pulmonary function and exercise capacity but also reduces frailty severity in elderly COPD patients. Integrating frailty-focused strategies into routine COPD management may improve outcomes and quality of life in this population.

Effect of High-intensity Interval Training on the Lung in Patients With COPD Referred for Lung Volume Reduction Surgery: The PREGENERATE Trial

Patients with chronic obstructive lung disease (COPD) suffer from a progressive loss of lung function that leads to poor quality of life, and often invalidity and early death. Regular exercise can improve quality of life in these patients, but there is a lack in understanding the underlying mechanism of exercise-induced improvement in COPD and it is widely thought not to have any effect on the lung as such. In the present study, the investigators aim to investigate the impact of an extensive high-intensity interval training (HIIT)-based exercise scheme on the regenerative capacity of the lung in patients with COPD on waiting list for lung volume reduction surgery. Design: Prospective randomized controlled clinical trial. Intervention: 24 persons with COPD referred for lung volume reduction surgery will randomly be allocated (1:1) to prehabilitation with high intensity interval training (HIIT) or non-exercise control. Outcomes: The primary outcome is differences in change in differential protein composition in distal lung tissue between HIIT and control groups post-intervention using spatial multimodal proteomics. Furthermore, lung tissue mass, protein composition (mass spectrometry and spatial omics e.g. MACSima), pulmonary blood volume, blood protein profile (biomarkers), diffusion capacity at rest and during exercise, oxygen consumption tests, body composition scan, distal airspace radii and physical functional tests will be measured before and after the intervention. Perspective: This study may fundamentally change the view on the regenerative potential of the lungs in COPD.

The study will test whether the intervention improves health status compared with usual care. Secondary outcomes include inhaler technique, medication adherence, health knowledge, dyspnea, clinical events, healthcare utilization, and costs. Participants in the intervention group will receive pharmacist guidance and use the serious game at home for 2 weeks.

University of Michigan COPD Identification Through Lung Cancer Screening Cohort Study - MAP2

The purpose of this study is to obtain new knowledge regarding screening for COPD. This study will use a participant's cancer screening CT scans performed as part of routine health care among current and former smokers at risk for COPD to identify participants who have had a spirometry or will have a spirometry test as part of the study to verify COPD status.

Impact of Combined Cardio-pulmonary Assessment on COPD Clinical Management.

The goal of this randomized clinical trial is to learn whether a combined cardio-pulmonary assessment improves cardiac function, exercise capacity, cardiac biomarkers and health-related quality of life in adults with mild-to-moderate chronic obstructive pulmonary disease (COPD) who are at high cardiovascular risk or have established cardiovascular disease. The main questions it aims to answer are: * Does the combined cardio-pulmonary assessment improve mean left ventricular ejection fraction (EF) over 12 months compared with standard respiratory care? * Does the combined cardio-pulmonary assessment improve mean 6-minute walk distance (6MWD) over 12 months compared with standard respiratory care? * Does the combined cardio-pulmonary assessment reduce mean NT-proBNP over 12 months compared with standard respiratory care? * Does the combined cardio-pulmonary assessment improve mean Kansas City Cardiomyopathy Questionnaire (KCCQ-12) score over 12 months compared with standard respiratory care? Researchers will compare a combined cardio-pulmonary assessment to standard respiratory care to see whether the integrated approach leads to greater improvements in EF, 6MWD, NT-proBNP, and KCCQ-12. Participants will: * Be randomly assigned to receive either a combined cardio-pulmonary assessment or standard respiratory care * Complete a baseline visit that includes clinical assessment, respiratory function testing, blood tests (including NT-proBNP), a 6-minute walk test, and the KCCQ-12 questionnaire * Undergo cardiovascular evaluation (electrocardiogram and transthoracic echocardiography) if assigned to the combined assessment group * Attend follow-up evaluation at 12 months, repeating the same assessments according to their assigned group
