Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

INTRODUCTION: The complexity of the pathophysiology of heterogeneous diseases such as heart failure and obstructive pulmonary disease causes a different approach to these diseases or with a view as much as a better understanding of the same situations, with which the clinical profile of patients who are associated with an association is. It is known that regular physical training promotes progressive improvements in exercise tolerance, in the pulmonary ventilation / perfusion ratio and in respiratory function by strengthening. OBJECTIVE: To compare the effects of high-intensity interval training and continuous aerobic exercise, with peripheral endothelial function, brain natriuretic peptide levels, maximum exercise tolerance, distribution of lung volumes and quality of life of patients with obstructive pulmonary disease associated with heart failure. METHODS: This is a clinical, controlled, randomized and blinded trial. Peripheral endothelial function, tolerance to maximum and submaximal exercise, distribution of lung volumes, quality of life, presence of symptoms of depression and perception of clinical change will be evaluated. EXPECTED RESULTS: Incorporate into the care of these patients, new effective therapeutic approaches, of low cost and with greater technical and scientific evidence.

This study will determine the dyspnea response in chronic lung disease volunteers during treadmill walking with and without added inspiratory resistance. This study will also determine the level of dyspnea and exercise sense of effort in individuals walking on a treadmill when elevations occur. Comparisons will be made of a participant's exercise response with and without increased inspiratory resistance. In this study, exercise performance will be analyzed based on physiological and perceptual measures. The participant will undergo two sessions: one session will be a standard exercise walking test without an inspiratory resistance; the other session will be the same standard exercise walking test while breathing with an inspiratory resistance equal to a N95 facemask (R=10-15 cmH2O/L/sec). Performance will be determined by physiological measures. Perception will be determined by scores based on numerical scales and automatically with the forehead Vitality remote monitoring sensor.

Chronic obstructive pulmonary disease (COPD) prevalence, morbidity, and mortality vary across countries and across different groups within countries with a direct relation to the prevalence of tobacco smoking. Other risk factors for COPD include genetic factors, longstanding asthma, outdoor air pollution, second-hand smoke exposure, biomass smoke, indoor air pollution, occupational exposures, and tuberculosis . The prevalence and burden of COPD are projected to increase in the coming decades because of continued exposure to COPD risk factors and the changing age structure of the world's population. As these factors are rapidly increasing in developing countries, COPD will become a major health problem, exerting a huge demand on economic and healthcare resources in developing countries [2]. In Egypt, although COPD is a rising significant health problem, data on its prevalence, morbidity, and mortality are still lacking and have to be estimated . Sirtuin 1 (SIRT1) is a protein/histone deacetylase dependent NAD. It plays a crucial role in various human diseases such as cardiovascular diseases, cancer, inflammation, aging, neurodegenerative disease, obesity and type 2 diabetes. Seven isoforms of the SIRT1 gene (SIRT1- SIRT7) have been determined in mammals. Expression of the SIRT1 gene is regulated by transcription factors such as CREB, FOXO3, HIC1, NF-KB, p53, PARP-2 and PPAR. SIRT1

The aim of pulmonary rehabilitation is to improve exercise capacity and reduce dyspnoea. As well as improving the patient's overall condition, pulmonary rehabilitation provides a means to monitor the patient regularly. During physical exercise, the increased activity of the muscle system increases cardiac and respiratory output. If the patient's respiratory status deteriorates, as occurs, for example, before the onset of an exacerbation, exercise capacity could be reasonably expected to reduce. The investigators hypothesised, therefore, that changes in the physical capacity of patients with COPD during a rehabilitation session could provide a predictive indication regarding the risk of occurrence of exacerbation.

This prospective study will be held in two steps. The aim of the first step is to assess the technical validity of transmitting data remotely from different devices connected to a telerehabilitation system. These will include real-time oximetry data during exercise on a cycle ergometer (heart rate and transcutaneous oxygen saturation) as well as daily step count from a commercially available physical activity tracker. The aim of the second step of the study is to assess the clinical feasibility of using the telerehabilitation system in real life conditions (in the home environment). Briefly, participants will benefit from a eight weeks pulmonary rehabilitation program performed at home, using the telerehabilitation system. Further details about the content of the program and the outcomes are provided below.

This study aims to investigate the clinical characteristics and heterogeneities of early chronic obstructive pulmonary disease (COPD), to determine the disease development of early COPD, and to establish a multidimensional model for predicting the outcomes of early COPD.

The principal objective of the study is to measure parameters of inflammation, oxidative stress, and vascular, respiratory, and peripheral muscle function parameters, and identify parameters indicative of evolving cardiovascular risk (CVR) in COPD patients, using multivariate analysis.

This research project incorporates a series of studies to investigate the relationship between physical performance (e.g. tests of strength, balance and walking distance) and physical activity (activity measured in day to day life) in people with COPD and other chronic lung diseases.

This is the registry of control participants for patients with various respiratory diseases. We screened healthy volunteers who visited Seoul National Hospital Healthcare System Gangnam Center for routine health check-up, and enrolled patients who agree to participate in the study. The participants undergo baseline questionnaires, provide blood specimen and information of the results of health check-up. We will include participants as controls if they have no significant respiratory symptom and no significant radiographic abnormality. The data from this registry will be compared with those from other registry of various respiratory diseases
