Filter by:The aim of this multi-center, randomized controlled pilot- and feasibility trial is to evaluate the user satisfaction, reach and safety of My COPD, a novel eHealth tool for remote delivery of evidence-based treatment targeting people with chronic obstructive pulmonary disease (COPD). In addition, the investigators aim to collect and synthesize data on clinical outcome measures to inform the sample size estimation of a later, definitive trial.

The risk factors and causes of chronic obstructive pulmonary disease（COPD）are not clear, so the prevalence of COPD is high and the prevention effect is not good. Because the pathogenesis of COPD is not completely elucidated, the diagnosis and classification of COPD are inaccurate which resulting in poor efficacy of treatment. Therefore, it is of great scientific and clinical significance to find out the risk factors and causes of COPD, to clarify its pathogenesis, to put forward the prevention and early intervention measures of COPD, to warn the occurrence of COPD, to predict the deterioration of the disease, to reduce the occurrence of COPD and to slow down the progress of COPD. The project establishes a cohort of COPD people，high-risk group and the healthy group. The project studys the risk factors, etiology and pathogenesis of COPD. The project studys the interaction between genetic factors and environmental factors on COPD and its effect on pathogenesis, progression and outcome of COPD.
Chronic obstructive pulmonary disease (COPD) is a condition characterized by airway obstruction. Patients with COPD experience significant shortness of breath on exertion. The mechanisms responsible for shortness of breath on exertion are well understood in moderate and severe COPD, but, are poorly understood in mild COPD where symptoms appear disproportionate to the degree of airway obstruction. Mild COPD patients show an exaggerated breathing response to exercise, determined by the breathing response to carbon dioxide production (V̇E/V̇CO2). Recent work suggests that the increased V̇E/V̇CO2 during exercise in mild COPD is secondary to increased deadspace (i.e. lung regions with ventilation but no perfusion) and/or ventilation/perfusion (V̇A/Q) inequality (poor matching of ventilation to perfusion). Researchers have proposed that the increased deadspace or V̇A/Q inequality is secondary to pulmonary vascular dysfunction and hypoperfusion of the pulmonary capillaries. Recently, we have shown that inhaled nitric oxide, a potent dilator of pulmonary vasculature, reduces shortness of breath and V̇E/V̇CO2, and improves exercise capacity in mild COPD. This preliminary finding suggests that pulmonary vascular dysfunction is an important contributor to exercise intolerance in mild COPD. Here, we aim to test whether sildenafil, an oral pulmonary vasodilator, can improve exercise tolerance and shortness of breath in mild COPD.
The prevalence of chronic obstructive pulmonary disease (COPD) in Turkey is 10%. Patients with COPD have a decreased physical capacity. Decreased physical activity in COPD patients causes an increase in all-cause mortality. Pulmonary rehabilitation contributes to increasing physical capacity and quality of life in COPD patients. However, a limited number of patients have access to pulmonary rehabilitation. Some of the patients drop out of pulmonary rehabilitation due to reasons such as transport difficulties, low social support, and low professional support. In addition, disruption of daily routine is one of the important reasons for this situation. Telerehabilitation can enable more patients to access pulmonary rehabilitation. Education and exercise programs can be followed with telerehabilitation in patients with COPD. An increase in exercise capacity and a decrease in dyspnea have been achieved with telerehabilitation in COPD patients. Different technologies such as telephone, video conferencing or web sites can be used for telerehabilitation. Also, mobile phone was used to telerehabilitation. To make pulmonary telerehabilitation completely patient-based, we have developed an application suitable for smartphones. The application contains videos which showing how to perform pulmonary rehabilitation exercise videos, and it allows the participants to follow up compliance with pulmonary rehabilitation daily. The application will be downloaded to the smartphones of the participants, and it will be shown how to use the application. Participants will not be shown pulmonary rehabilitation exercises. This study aims to evaluate the effectiveness of telerehabilitation with the application program on physical capacity, quality of life, and dyspnea perception in COPD patients.
As protocol NCT04223050. This substudy furthermore investigates the role of oxidative stress in the administration of oxygen in COPD patients.
To evaluate the safety, tolerability and pharmacokinetic characteristics of TQC3721 suspension for inhalation in single/multiple administration(s) in healthy subjects; to evaluate the safety,tolerability and efficacy TQC3721 suspension for inhalation in multiple administrations in patients with Chronic Obstructive Pulmonary Disease（COPD）and asthma.
Respiratory rehabilitation is an intervention proven to improve quality of life in those with chronic lung disease but access remains poor. The investigators will assess the feasibility and acceptability of a virtual platform for respiratory rehabilitation as an alternative to in person rehabilitation. The aim is to use the technology in those post admission with COPD where access has been even more of a challenge as during this period patients find it difficult to access an out patient program due to their frailty.
While the bidirectional relationship between the lung and the right heart are well studied, the cardiopulmonary interactions between the lung and the left heart are largely unresearched and not well understood. However, in recent years, there is a growing evidence that partially explains the bidirectional interaction between COPD and left heart. Systemic inflammation with multiorgan involvement is thought to play a role in COPD as a systemic disease. Some therapeutic approaches to COPD also appear to influence these cardiopulmonary interactions. While understanding these interactions is very important for clinicians, scientific data are scarce. Cardiac magnetic resonance imaging (cardiac MRI) is the gold standard for assessing cardiac function and dimensions as well as myocardial inflammation. Despite this excellent suitability of cardiac MRI for the assessment of cardiovascular function, only few studies have investigated cardiac function and myocardial structure in patients with pulmonary disease using cardiac MRI. Such a study is therefore very important for understanding the effects of pulmonary disease and its management on the heart. The objective is to determine cardiac function in patients with pulmonary disease and to analyze the cardiovascular effects of the treatment of the pulmonary disease. Specifically, the following will be studied: - Using cardiac MRI: Cardiac function and volumes and indications of myocardial fibrosis and edema in patients with chronic pulmonary disease at the time of first diagnosis. - the vascular function of pulmonary arteries in these patients, also using cardiac MRI - the relationship between pulmonary function parameters and cardiac dysfunction to identify patients at increased risk, if applicable. - Echocardiographic assessment of left heart including strain analysis. - the course of these cardiovascular parameters (using cardiac MRI and echocardiography) 3-6 months after initiation of guideline-based therapy for pulmonary disease.
