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

To develop and validate a library of cough spectrum from a target of 1000 cough acoustics. Coughs arising from upper respiratory infection, lower chest infections, asthma, allergic conditions are included in the study. Cough acoustic in absence of respiratory disease is also included. This is a prospective observation cohort study recruiting children below the age of 16 years old in 2 arms : (1) Patients with respiratory conditions presenting with cough and (2) Well patients without active coughing.

The aim of this study is to investigate the association between endothelial dysfunction, measured by RHI as assessed by the peripheral arterial tonometry method, and PE complications defined as re-event of PE or DVT, systemic embolism or all-cause mortality

the investigators aim to set up a multicenter registry study for severe PJP requiring ICU admission. The purpose of this study is to establish a prospective severe PJP registry about clinical characteristics, laboratory and radiographic findings, critical care management and outcomes. to explore the predictive factors associated with outcomes ; to compare the difference between PJP patients with HIV and without HIV infection.

This is an observational prospective multicenter study of patients admitted for acute dyspnea in an emergency department of the participating centers in the Lorraine district. The primary objective is to assess the outcome of this population according to the cause of acute dyspnea as well as identify the predictors of this outcome, both overall and according to each acute dyspnea cause.

Burn injury leads to hypovolemic then distributive shock. Fluid resuscitation remains the cornerstone of initial treatment of burn shock. However, fluid rescucitation can lead to fluid overload, which manifests most notably as lung edema. The peptide NT-pro-BNP, a biomarker of cardiac congestion secreted by the myocardium, as well as plasma CD146, an endothelial factor involved in angiogenesis and a marker of vascular congestion, may help identifying patients with risk of pulmonary edema and hypoxia . Our hypothesis is that these biomarkers may predict the occurence of pulmonary edema in severe burns patients.

This is a 3 year longitudinal study to establish a personalized prediction and prevention system for acute exacerbation of chronic obstructive pulmonary disease（AECOPD). Data will be collected which contained with clinical, pathophysiology, etiology and immunology information of chronic obstructive pulmonary disease(COPD) patients and analyzed by data mining combined with Internet technology.

The subjects of this study are the chronic obstructive pulmonary disease (COPD) patients with chronic II respiratory failure. The participants will be divided into two groups: The Portable Home Noninvasive Ventilator treatment group and the routine home oxygen inhalation treatment group. All subjects will be given a stable COPD regimen and conventional oxygen therapy ,but the portable home noninvasive ventilator treatment group will need to wear a portable non-invasive ventilator. Objective evaluation indexes were established during the routine treatment, and two groups of subjects will be followed up for one year. Finally, the clinical data of all subjects will be analyzed，and then the practicability of portable wearable household noninvasive ventilator will be verified.The researchers will also build a remote breathing data-monitoring platform based on mobile internet,and a community home demonstration application point.

This is a small pilot / feasibility study (Approximately 50 patients) to assess the possibility of clinical implementation of MRI assessment of patients with cystic fibrosis and primary ciliary dyskinesia. Patients will undergo their standard CT imaging and lung function investigations and additionally will undergo MRI examination. Reports from CT (the current gold standard) and MRI will be assessed for concordance and patient acceptability and examination implementation costs will also be assessed. Novel MRI-based potential markers of CF and PCD disease state will also be assessed.

Detection of gastrointestinal complications in mechanically ventilated critically ill patients and its relation to oropharyngeal and respiratory infections in relation to oropharyngeal and gastric PH.

The purpose of this study is to validate the method of analysing Positron Emission Tomography (PET) images to assess lung inflammation. Development of novel therapeutic drugs requires a biomarker which is sensitive to the underlying disease and can respond to therapeutic interventions. PET is a potential imaging biomarker which can target molecular and cellular processes. There is currently no standardised method of analysing PET lung data and a lack of validation for the existing techniques. This study is divided in to two parts. Part A aims to determine the best method to perform 18F-FDG PET/CT lung analysis and how it correlates with cell counts from bronchoalveolar lavage (BAL) samples taken from participants with active pulmonary sarcoidosis. Part B will compare imaging data from healthy volunteers who have either undergone a Lipopolysaccharide (LPS) challenge (whereby the lung is temporarily inflamed) or saline equivalent to determine whether lung inflammation can be detected by 18F-FDG PET/CT. No medications will be given and patients will not be asked to stop or change existing medication.
