Filter by:Using various types of inhalers is the treatment cornerstone for COPD patients to control their symptoms. Many inhaler devices require minimum inspiratory effort to activate the device, COPD patients commonly use such devices. Those devices deliver the medications only when the patient forcefully inhales so the drug can reach the lungs, thus exerting their therapeutic action. The effect of appropriate use of the inhalers in patients with COPD is not well studied, and the impact of demonstrating that a patient can inhale forcefully enough to activate a device on its' effect on symptoms is also lacking in the medical literature. The purpose of this study is to find out: 1. the frequency of COPD patients demonstrating an appropriate use of inhalers that have flow-triggered systems, 2. whether the appropriate use of inhalers impacts the Quality of Life and Shortness of Breath of COPD patients, and 3. the impact of appropriate use of inhalers on FEV1 in COPD patients.
The SIDERA^B telerehabilitation system is enabled by a multi-domain, multi-device platform providing at home multi-component rehabilitation, targeting cardiovascular (Chronic Heart Failure, CHF), pulmonary (Chronic Obstructive Pulmonary Disease, COPD) and neurodegenerative (Parkinson Disease, PD) chronic diseases. The rehabilitation program embeds engagement activities for patient and caregiver, to empower appropriation of the SIDERA^B care routines and fuel their well-being resources. The multidisciplinary layering of SIDERA^B is reflected in the validation protocol including a) clinical and well-being evaluation through a cross-over study confronting usual care with the SIDERA^B activities; b) technological evaluation: Health Technology Assessment for organizational, legal and equity impacts; c) economic evaluation: process mapping and budget impact analysis to define a sustainable reimbursement process for the innovative telerehabilitation pathway.
COPD is a common, preventable and treatable disease associated with an increased chronic inflammatory response of the airways and lungs to harmful gases and particles and characterized by progressive airflow restriction, which is usually progressive. Exercise intolerance is one of the most important outcomes of COPD. Dyspnea and leg fatigue are the main symptoms that limit exercise and patients restrict their activity to avoid these disturbing conditions. Exercise training is the most appropriate method for improving exercise tolerance and muscle function. It is considered and recommended by ERS and ATS as an essential component of PR. Endurance training is considered to be one of the most important components of the PR program. Walking, running, cycling, stair climbing, dancing are examples of endurance exercises. Dance-based exercise training; It is an entertaining method that increases physical, functional, cognitive, emotional and social integration. This alternative method has frequently been tried in the literature in the treatment of Parkinson's, cancer and psychiatric diseases and its effects on functional capacity, balance, and quality of life have been demonstrated. The importance of our research; This is the first study to apply dance based exercise training in chronic respiratory diseases. The aim of this study was to investigate the effect of creative dance based exercise training on respiratory, balance and cognitive functions, respiratory and peripheral muscle strength and functional capacity in COPD patients.
A Multicenter, Randomized, Double-blind, Placebo-controlled, Parallel Group, Phase 2a Study to Explore the Efficacy and Safety of Tezepelumab in Adults with Moderate to Very Severe Chronic Obstructive Pulmonary Disease (COPD)
Fatigue is a prevalent symptom in Chronic Obstructive Pulmonary Disease (COPD) that limits patients in their daily living activities. It is now well established that COPD patients may have altered neuromuscular functions compared to healthy individuals. However, the different studies conducted on muscle fatigue in COPD have been done independently of any cognitive solicitation, yet present in most of daily living activities. Therefore, the aim of this research is to evaluate the impact of the disease on neuromuscular fatigue during dual-task situation (simultaneous accomplishment of a muscle contraction and a cognitive task). A better understanding of fatigue in COPD will promote the development of new perspectives in patient management. The hypothesis is that COPD patients will exhibit increased fatigue level (compared to healthy subjects), particularly during dual-task situation. It is assumed that the higher negative effect associated with the dual-task will be related to different neurophysiological mechanisms (i.e., neuromuscular fatigue, autonomic nervous system activity, mental fatigue).
This study is designed to provide preliminary information regarding how to improve pulmonary rehabilitation for persons with chronic obstructive pulmonary disease (COPD). Pulmonary rehabilitation is an exercise program for COPD patients that is recommended and benefits some, but not all, patients. The question being studied in this trial is whether walking on an incline might be better than walking on faster on a flat surface in training muscles so that patients might be less short of breath with exercise.
Rationale: Chronic Obstructive Pulmonary Disease (COPD) is defined by airway obstruction. However, the degree of airflow limitation does not adequately describe the complexity of COPD because significant heterogeneity exists between patients with respect to their clinical presentation, physiology, imaging, response to therapy, decline in lung function and survival. Currently, a clear alternative for describing COPD does not exist but the identification of subgroups of COPD patients based on clinical or genomic and epigenomic factors (phenotypes) could be useful. The continuous flow of very severe COPD patients to the UMCG gives the investigators the unique opportunity to perform a study on the phenotypes of very severe COPD and the underlying gene-environment interaction. The investigators anticipate that the findings of this study will lead to an earlier identification of those subjects who are at risk to develop severe or very severe COPD. In addition, it will lead to a better clinical characterisation of established COPD, possibly enabling a more tailored treatment of different COPD subphenotypes. Objectives: Primary Objective: To identify new clinical phenotypes in patients with severe chronic obstructive pulmonary disease (COPD) using a cluster analysis. Secondary Objectives: To: - identify clinical phenotypes (based on e.g. lung function, clinical, radiologic, systemic, pathological and immunological parameters) in patients with severe COPD. - identify endotypes/ intermediate phenotypes in patients with severe COPD. - investigate the contribution of (epi)genomics (including genetics and gene expression) to characterize patients with subsets of severe COPD. Study design: Observational cross-sectional study with a 2 phase design Study population: Patients with severe COPD who are referred to the UMCG for a consultation on lung transplantation or bronchoscopic lung volume reduction.
The Investigator would like to study the effect of yoga exercises and meditation on lung volume, respiratory impedance, 6-minute walk distance and quality of life in COPD patients.
Chronic obstructive pulmonary disease (COPD) is one of the most common diseases worldwide and is considered a public health problem. The World Health Organization estimates that about 210 million people have COPD. Disease-related mortality is more than 3 million, representing 5% of all deaths, 90% of this mortality being concentrated in middle- and low-income countries. COPD can be subdivided into chronic bronchitis and emphysema. Emphysema, the focus of this project, is histologically defined by the permanent increase of the distal air spaces to the terminal bronchioles associated with the destruction of the alveolar septa in the lung. Approximately two-thirds of adult men and a quarter of women (most without dysfunction) will have well-defined emphysema, but often of limited extent. Mesenchymal stem cells (MSCs) have anti-inflammatory, anti-fibrotic, microbicide and repair potential. Regarding COPD, several authors have concentrated efforts in the investigation of the relationship between the severity of the condition and the various sources of adult stem cells. Apparently the lungs have a high chemotactic effect in relation to adult stem cells, since several studies have evidenced a high implantation (6-20%) of stem cells derived from bone marrow, administered systemically, in the pulmonary tissue of receptors. Therefore, MSCs has been tested in different lung diseases have no effective treatment, such as pulmonary fibrosis, acute respiratory distress syndrome, asthma, COPD positive results, such as reduction of fibrosis, reduction of proliferation inflammatory cells and cytokines, reduction of infectious processes and recovery of the histological changes caused by pulmonary emphysema. Based on these findings, the purpose of this project is to evaluate the safety and efficacy of endoscopic administration of bone marrow stem cells in patients with severe homogeneous emphysema and evaluating the feasibility, efficacy and safety of this procedure.
Chronic obstructive pulmonary disease is a major cause of disability and mortality worldwide. This disease progressively leads to dyspnea and exercise capacity impairment. Pulmonary rehabilitation teaches chronic obstructive pulmonary disease patients to cope effectively with the systemic effects of the disease and improves exercise capacity, dyspnea and quality of life in patients with chronic obstructive pulmonary disease. However, the best training modality remains unknown. Physiological studies highlight the benefit of high intensity endurance training. However, many patients do not tolerate such a training due to ventilatory limitation and dyspnea. Therefore, a strategy to reduce dyspnea would allow a greater physiological muscle solicitation and improvement. Thus, many studies focus on means to increase exercise tolerance in patients with chronic obstructive pulmonary disease. Nasal high flow delivers heated and humidified high flow air (up to 60 L/min) through nasal cannula providing physiological benefits such as positive airway pressure and carbon dioxide washout. It can be used in association with oxygen and offers the advantage to overtake the patient's inspiratory flow, providing a stable inspired fraction of oxygen. Nasal high flow has widely been studied in pediatric and adult intensive care units and seems better than conventional oxygen therapy and as effective as noninvasive ventilation with regards to mortality to treat hypoxemic acute respiratory failure. More recently, nasal-high flow has been shown to improve endurance exercise capacity in patients with chronic obstructive pulmonary disease. However, the underlying physiological mechanisms have not been yet elucidated but may help to optimise the utilization of the device. Therefore, the primary objective of this study is to assess the respiratory physiological effects nasal high-flow during-exercise in stable patients with chronic obstructive pulmonary disease. Secondary objectives are to assess the effects nasal high-flow during-exercise on endurance capacity, respiratory drive, dynamic hyperinflation, cardiorespiratory pattern and muscular metabolism.
