Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

The aim of this study is to assess the perception of chronic obstructive pulmonary disease (COPD) patients in symptoms related to morning activities. Also the researchers investigated how to describe the impact of symptoms on sleep quality and how to use the medication in Korea COPD treatments.

Some patients with chronic obstructive pulmonary disease (COPD) need supplementary oxygen during air travel. Guidelines issued by The British Thoracic Society (BTS) for pre-flight evaluation do not discriminate sufficiently between those who need supplementary oxygen during flight, and those who can do without. Previous studies have indicated that decreasing hemoglobin oxygen saturation during exercise may predict in-flight hypoxemia. The objective of the present study is to examine if adding exercise oxygen desaturation to the BTS algorithm will better predict requirements for in-flight supplementary oxygen.

The main objective of the study is to evaluate the predictive factors of the endothelial function to the waning of an acute exacerbation in COPD. It will act to do a multivariate analysis to determine the respective weight of the parameters of the systemic inflammation, of the oxidative stress of the functional respiratory parameters and then functional respiratory parameters. In exacerbated Chronic Obstructive Pulmonary Disease (COPD) patients, there is augmentation of hypoxia and the obstructive ventilatory disorders is more important. This is correlated with an increase in C-reactive Protein (CRP) and of inflammatory cytokines and oxidative stress. It has been demonstrated that there is an endothelial dysfunction in answer to hypoxia. Since the exacerbated COPD patients are hypoxic in most cases , we suppose they have an endothelial dysfunction during exacerbation. So we think we will find an augmentation of vascular resistances ,shown by a peripheral arterial tone too high. And this, certainly, play a part in physiopathology of the COPD exacerbation.

The purpose of this protocol is to obtain biologic samples from the blood and lungs from patients with lung diseases in order to study the causes and indications of these disorders, learn how these lung disease manifest and progress, and how the lung disease can be treated.

Obstructive lung disease is usually a differential diagnostic consideration when a patient presents with breathlessness or cough. Spirometry is the key diagnostic test used to confirm airflow obstruction particularly in the primary care setting. Airflow obstruction that completely resolves after administration of a bronchodilator, by definition, excludes a diagnosis of COPD. Evaluation of obstructive lung disease must include pulmonary function testing; bronchoreversibility testing is an adjunct in differentiating between asthma and COPD. Bronchoreversibility cannot serve as an absolute diagnostic criterion for separating asthma from COPD. Vibration response imaging (VRI) technology provides a simple, radiation-free method to image the lungs, by visualizing vibration energy (lung sounds) emitted during respiration cycle. In this study, regional quantitative and qualitative information on vibration response is compared with spirometry in assessing lungs function of COPD and Asthma patients.

More and more general practitioners (GPs) use spirometry in their practices. At this time, there is sufficient reason to presume that, after a single postgraduate training program without any further support, most GPs have insufficient knowledge and ability to assure valid interpretation of their spirometry tests. Therefore, some kind of continuous diagnostic support with regard to spirometry interpretation by GPs is advisable. The aim of the present study is to assess whether implementation of spirometry expert support (either by a computerised expert system or a working agreement between general practitioners and respiratory consultants with respect to spirometry interpretation) causes changes in diagnosing and appropriateness and efficiency of medical care in subjects with chronic respiratory morbidity managed in general practice.

This 31-month supplement to Sustaining Women's Smoking Cessation Postpartum (Project PANDA) designed, implemented, and evaluated an intensified intervention for pregnant women who were unable to stop smoking with minimal assistance.

This study is conducted as a multicenter, non-interventional, cross-sectional study. Patients will be enrolled in the study by a continuous registration method after patients provide written informed consent. After providing informed consent, patients will answer the questionnaires and start measurement with an accelerometer within four weeks. Activities will be measured for 14 consecutive days.

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.

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.
