Active clinical trials for "Lung Diseases, Obstructive"

Smokers do not know the symptoms of cancer and wait on average 5 months with symptoms before consulting. 80% of lung cancers are diagnosed at too late and incurable stage. Systematic CT screening of smokers is under evaluation and currently not supported because expensive and little used in real life (in the US 1.8% of smokers after 7 years of establishment in the USA). An English study showed an increase in the number of operable stage cancers of 3% among smokers by calling them on a trailing cough by a simple poster campaign ("You smoke, you cough for more than 3 weeks, consult"). Regarding COPD, it is linked to tobacco in 85% of cases, affects 3.5 million French and is in 2013 the 4th leading cause of death in France. The evolution of COPD is marked by exacerbations, period of acute aggravation of symptoms, responsible for the deterioration of the quality of life or even hospitalization or death. COPD remains a silent killer responsible, according to this same summary review, of 16,500 deaths per year in France. Dr DENIS has developed a web application that has shown a 7-month survival benefit by early detection of lung cancer relapses based on the reporting of patient symptoms analyzed by a validated algorithm in 300 patients and 1 randomized trial. The Applitabac app takes this concept of symptom self-assessment by patients. By multiplying the number of symptoms analyzed compared to the English study, Applitabac should be able to increase the sensitivity of this early detection of COPD and increase the number of operable bronchial cancers and increase the chances of survival of patients.

This cross-sectional study aims to investigate what daily activities increase the risk of falling in Chronic Obstructive Pulmonary Disease patients (COPD).

In the literature, most of the studies examining the gait characteristics and balance separately or examining the relationship between them are on patients with COPD. No study examining gait parameters in other obstructive pulmonary patients such as bronchiectasis and asthma was found.A convincing link between gait disturbances and falls in COPD patients is still unknown and further research is needed. Therefore, the purpose of our study; gait parameters and balance in individuals with obstructive pulmonary disease. We will also examine the relationship between gait parameters and extrapulmonary clinical indicators of these individuals.

The aim of this study is to measure the actual use time in patients receiving supplemental oxygen using a new easy-to-use electronic remote monitoring device (TeleOx™)

Despite the high prevalence of chronic obstructive pulmonary disease (COPD), there continues to be a large gap in our understanding of disease pathogenesis and mechanisms accounting for large variability in disease phenotype. Untargeted metabolomics is an ideal approach to uncover the metabolic basis of disease, as well as discover unique drug target opportunities aimed at these nodal metabolic drivers of disease. There are very limited data from metabolomics studies from plasma/serum and exhaled breath condensate that suggest certain metabolic pathways or metabolites might predict the presence and/or severity of COPD phenotypes. Here, the investigators hope to generate comprehensive, compartment specific (blood and lung) metabolite profiles that will be correlated with various clinical phenotypes of COPD, using a complementary approach of untargeted nuclear magnetic resonance (NMR) and liquid chromatography (LC)- mass spectroscopy (MS) -based metabolomics.

This project will observe and follow up the changes of pulmonary function and CT in patients with smoking combined with pulmonary tuberculosis, and measure the ratio of Th1 cells, Th17 cells, macrophages and neutrophils and the secretion of factors such as TNF-α, IFN-γ and IL-17 in pulmonary blood and alveolar lavage fluid.

Observational, cross-sectional study with retrospective data collection from medical records. During the cross-sectional study visit, data will be captured through the use of electronic Case Report Forms (eCRFs). As there will be only one study visit, no prospective data collection will take place, nor collection of data that are not part of the routine clinic visit. For understanding the burden of severe exacerbations of COPD and the association between frequency of severe exacerbations and clinical and health-care utilization outcomes in less well-resourced countries

Data from chronic obstructive pulmonary disease patients awaiting lung transplantation which performed a pulmonary rehabilitation program will be analyzed retrospectively. Acute exacerbations occur frequently in these patients and have a major impact on the course of the disease. This study investigates the prevalence and the impact of acute exacerbations during pulmonary Rehabilitation in patients with severe chronic obstructive pulmonary disease patients awaiting lung Transplantation that continued the Rehabilitation program despite an acute exacerbation. Data will be taken from the internal database of the reference center (Schoen Klinik Berchtesgadener Land, Schoenau, Germany) where these data were collected during clinical routine.

Study of the energy supply of bicycle ergometric load in athletes and untrained persons with bronchopulmonary diseases (community-acquired pneumonia, bronchitis, chronic obstructive pulmonary disease and acute respiratory viral infections, to justify the timing of the resumption of training, as well as determination of the volume and intensity of physical activity in training and competitive processes.

Chronic Obstructive Pulmonary Disease (COPD), , secondary to smoking, is a major public health issue with very high direct and indirect costs. The impact on the health system of undiagnosed patients, up to 70% of patients, is increasingly documented. However, systematic spirometry screening remains controversial among smokers in the absence of data to link the detection of new patients with improved management and clinical events and health goals. More generally, there is little data on the evolution of patients in real life once they have entered the care system. The premise is that with systematic screening in general medicine, it is possible to identify the evolution of newly diagnosed COPD patients, to distinguish the different possible evolutions according to the initial phenotype and the management.
