Serum, Plasma, DNA and Tissue Bank in Chronic Obstructive Pulmonary Disease and Lung Cancer

Chronic Obstructive Pulmonary DiseaseLung Cancer

A biobank of Serum, plasma, DNA samples together with clinical information including specific questionnaires, complete pulmonary function and chest CT-scan, is prospectively collected in patients seen at the investigators' clinical service. The objective is to study candidate gene pathways in COPD and or lung cancer and to associate them with the clinical characteristics and phenotypes of COPD/emphysema and lung cancer. In subgroups of well characterised patients, other biological materials are also collected (lung tissue biopsies, peripheral blood mononuclear cells).

A Study on the Microcirculatory Characteristics of Meridian Phenomenon for the Heart and Lung Meridians...

Chronic Obstructive Pulmonary Disease

Although some important progresses were made in the field of the meridian research, no breakthroughs have been achieved. Besides,there are some problems in meridian researches. Particularly, previous research of meridian phenomenon involved lots of subjective elements and outcomes.Researches that use modern scientific techniques to investigate the biological characteristics of meridian phenomenon are urgently needed. Therefore, this study is designed to assess the microcirculatory characteristics of meridian phenomenon for the Heart and Lung meridians by using laser doppler. Thus, the biological characteristics of meridian phenomenon could be presented objectively in a scientific methodology

Usefulness of the Chronic Obstructive Pulmonary Disease-population (COPD-PS) Questionnaire and the...

Chronic Obstructive Pulmonary Disease

The aim of this study is to evaluate the usefulness of the chronic obstructive pulmonary disease-population questionnaire (COPD-PS) and the COPD-6 device in the early detection of chronic obstructive pulmonary disease in smoker patients .

Prevalence of Respiratory Impairment During IBD

Chronic Obstructive Pulmonary DiseaseAsthma2 more

Patients will be recruited during a routine consultation with a physician in the hepato-gastroenterology department. At the end of the consultation, patients will have to complete the following questionnaire: "European Community Respiratory Health Survey" which allows the screening of patients at risk of chronic respiratory diseases (asthma, COPD, bronchiectasis, emphysema). In the event of a declaration of functional respiratory signs, a consultation with a pulmonologist will be systematically proposed. At the end of this consultation, if the doctor deems it necessary, further investigations will be proposed and/or regular follow-up organised. The main objective of this study is to estimate the prevalence of respiratory symptoms leading to a diagnosis of chronic respiratory disease in patients with inflammatory bowel diseases (IBD) (Crohn's disease and UC). The main criterion for judgement will be the frequency of functional respiratory signs (wheezing, dyspnea, cough, sputum) reported by IBD patients through an adapted self-report questionnaire.

Exercise Capacity in COPD

Chronic Obstructive Pulmonary Disease

In this study, cardiopulmonary exercise will be assessed to characterize the relevance of severity of COPD and coexisting cardiovascular comorbidities for exercise capacity.

The Microbiome of Sputum, Urine and Feces in Healthy Persons and Chronic Obstructive Pulmonary Disease...

Pulmonary DiseaseChronic Obstructive2 more

Extensive studies suggest composition of microbiome of respiratory samples or lung tissues in COPD patients is different from the composition of healthy smokers. Aim of this study is to analyze composition of microbiome of various samples (e.g. feces, sputum, and urine) and to describe difference of composition between COPD patients and healthy smokers.

Analysis of the Dynamics of the Lung Microbiota During Acute Exacerbation of COPD Requiring Admission...

Chronic Obstructive Pulmonary Disease

This study aims to investigate the correlation between pulmonary microbiota dynamics (including bacteria, fungi and viruses) and COPD exacerbation for COPD patients admitted to ICU

Prediction of Expected Length of Hospital Stay Using Machine Learning

InfectionHeart Failure7 more

This is a retrospective observational study drawing on data from the Brigham and Women's Home Hospital database. Sociodemographic and clinic data from a training cohort were used to train a machine learning algorithm to predict length of stay throughout a patient's admission. This algorithm was then validated in a validation cohort.

Dynamic Hyperinflation In Mechanically Ventilated Chronic Obstructive Pulmonary Disease Patients...

Pulmonary DiseaseChronic Obstructive

Chronic obstructive pulmonary disease is a common respiratory condition that is characterized by inflammation of the large and small peripheral airways , the alveoli and adjacent capillary networks. Severe airflow obstruction that imposes a significant load on the respiratory system is a major manifestation of Chronic obstructive pulmonary disease. The reduced expiratory airflow also causes air trapping at the end of expiration , producing alveolar pressure that are higher than atmospheric pressure before the next breath. This condition is intrinsic positive end-expiratory pressure .

Metabolic Changes in Patients With Chronic Cardiopulmonary Disease

Heart FailureChronic Obstructive Pulmonary Disease2 more

This study aims to evaluate prevalence of sarcopenia and cachexia in patients with chronic cardiopulmonary disease. The investigators will also investigate metabolic disorders like glucose metabolism, presence of metabolic syndrome, body composition and histological changes in skeletal muscle and body fat. Finally, patients will be followed for clinical endpoints.
