Active clinical trials for "Respiratory Tract (Lung and Bronchial) Diseases"

This registry was proposed to investigate the epidemiology of respiratory mechanics in patients with ARDS through collecting data from a QI project which was constituted with systematic assessments of respiratory mechanics and gas exchange.

Correlation of epithelial growth factor receptor mutation in blood of lung cancer patient and clinical outcome.

To understand 295 gene mutation mutation status (include EGFR, HER2, KRAS, BRAF, PIK3CA,ect) by deep sequencing in Chinese patients with pulmonary adenocarcinoma and their relationships with the patients' clinical features (including sex, age, smoking history and adenocarcinoma subtype), specify the predictive significance of the genes mutations for new targeted therapies in NSCLC patients, and better understand the molecular mechanism drug resistance to EGFR-TKIs.

Evaluating an integrated diagnostic work-up of virtual navigation bronchoscopy (VNB), confocal laser endomicroscopy and micro computerized tomography (micro-CT) in the diagnostic path of pulmonary lesions in the non-oncological patient.

The investigators propose to create a database at the regional level, the principle is to include all patients in whom a mutation was detected from a single platform (Lille). The creation of this regional cohort, smaller than the national cohort of Biomarkers France, will perform a more comprehensive collection of clinical data, and molecular monitoring data of patients included. To increase the completeness of the collection of information, it will not be based on voluntary prescribing clinician but will be largely carried out by CRA dedicated to this activity.

Chronic thromboembolic pulmonary hypertension causes progressive right heart hypertrophy, dilatation and dysfunction. Surgical treatment is pulmonary endarterectomy, which although only carried out in a single UK centre, provides an excellent model for assessing right ventricular function. Right heart function is most commonly assessed using echocardiography, either transthoracic pre- and post-operatively, or transoesophageal intra-operatively. Measurement of tricuspid annular plane systolic excursion is the best validated and most commonly performed measurement for right heart function, however it may be inaccurate after sternotomy and pericardial opening, making accurate assessment difficult immediately after surgery. Therefore, we aim to compare established methods of assessing right heart function with 3-dimensional echocardiographic reconstruction of the ventricle, using a novel reconstruction mechanism. Right ventricular function will be assessed in 51 patients who undergo pulmonary endarterectomy surgery at baseline, after the pericardium has been opened, following the surgical procedure, using transoesophageal echocardiography, and at six-month outpatient followup using transthoracic echocardiography, as 3D-reconstruction is valid using both modalities. This comparison should allow the investigators to determine whether such a method could replace current measurement parameters for assessment of right ventricular function, which is important for clinical management of patients in a variety of settings.

Assessment of health-related quality of life in COPD patients with severe chronic respiratory failure requires appropriate and highly specific measurement tools. We attempt to validate the Chinese version of the Severe Respiratory Insufficiency Questionnaire (SRI)

The investigators hypothesis is that there will be improvement in FEV1 in patients with severe asthma. This is a retrospective data study that reviews preexisting medical records; no patients will be enrolled.

Inhalation of dust containing asbestos results in a process of interstitial pulmonary fibrosis called asbestosis. The Forced Oscillation Technique (FOT) evaluates the respiratory mechanics describing resistive, elastic and inertial properties. We believe that this technique may contribute to the early diagnosis of asbestosis.

This multicenter retrospective observation study is designed to investigate the etiology of children with bronchiectasis by review the medical records.
