Active clinical trials for "Lung Diseases"

The objective is to verify that there is a decrease in the pulsed oxygen saturation with the digital sensor. That is, the drop in oxygen saturation in COPD patients during inhalation is real and not due to an artifact of the measuring tool, because oximeters need a quality pulsatile signal to properly measure oxygen saturation

The current severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic is complicated by pneumonia (15 to 20% of cases) requiring hospitalization with oxygen therapy. Almost 20 to 25% of hospitalized patients require intensive care and resuscitation; half die. The main cause of death is acute respiratory distress syndrome (ARDS). However, some deaths have been linked to pulmonary embolism (PE). Recognition of PE is important because there is specific treatment to limit its own mortality. The identification of biological parameters of hemostasis predictive of thromboembolic disease is crucial in these patients. To evaluate the frequency of PE in the patients having to be hospitalized is to practice of a systematic thoracic angiography scanner in the patients having no contra-indication for its realization, as well as during hospitalization in patients deteriorating without any other obvious cause. The thromboembolic events and disturbances of the coagulation system described in patients with SARS-CoV-2 pneumonitis suggest that this viral infection is associated with an increase in the activation of coagulation contributing to the occurrence of thrombosis and especially from PE.

This study aims to analyze the impact of a brief psychological support intervention in the promotion of the adherence to Non Invasive Ventilation (NIV) among people with Chronic Obstructive Pulmonary Disease (COPD). The investigators expect to see a positive impact of this intervention on both physical and psychological well-being, and consequently, a reduction of health costs.

The study contains the result from a comparison of diagnostic outcomes about lung collapse by using lung ultrasonography as a new diagnostic test compares to fiberoptic bronchoscopy as the standard test.

High-flow nasal cannula is an oxygenation technique increasingly used for patients admitted for acute respiratory failure. Literature essentially concerns "de novo" acute hypoxemic failure and the interest of high-flow during take care of chronic obstructive pulmonary disease patients is few studied. Physiological studies reported potential benefits of high-flow nasal cannula oxygenation in chronic obstructive pulmonary disease patients including dead space clearance and decrease of respiratory, which lead to decrease work of breathing. As inhaled bronchodilators are part of treatment of chronic obstructive pulmonary disease exacerbation, nebulization could be also provided through high-flow nasal cannula oxygen therapy. The aim of our study is to determine whether a beta-2 agonist nebulization administered through High-flow nasal cannula is efficient to improve spirometry of patients for admitted hronic obstructive pulmonary disease exacerbation.

Chronic Obstructive Pulmonary Disease (COPD) is a frequent disease, with increasing prevalence. Pulmonary rehabilitation through general exercise training (GET) is a corner stone of COPD care. Inspiratory muscle training (IMT) as a stand-alone therapy decreases dyspnea and improves exercise capacity. Whether IMT combined with GET adds a supplementary benefit in the rehabilitation of COPD patients is however uncertain.

N-acetylcysteine (NAC) is described as having mucolytic and antioxidant properties. It is widely prescribed for patients with chronic obstructive pulmonary disease (COPD), particularly for those who have accompanying symptoms of chronic cough and sputum production. Randomized, placebo controlled indicate that it is safe and that it may have some clinical benefit when used at relatively low doses. It is postulated that substantially higher doses of NAC will be well-tolerated and will provide better symptom control while also decreasing blood makers of oxidant stress and inflammation.

Some patients with a long history of AF develops PH "reactive" type with an increase in pulmonary vascular resistance due to vasoconstriction or structural changes of the vascular wall. RFA PVI + RFA GP is the "gold standard" in the treatment of patients with persistent AF, do not respond to optimal therapy. The rear area of the pulmonary artery bifurcation is adjacent to the roof and part of the front of the left atrium. In the projection of this area are ganglionic plexus of the left atrium, the sympathetic nerve fibers of the pulmonary artery and baroreceptors main pulmonary artery.Recent studies have shown that radiofrequency denervation of the pulmonary artery improves the quality of life in patients with PH.
