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

The aim of the present study is to influence the central and obstructive sleep apnoea in patients with severe mitral insufficiency by an interventional MitraClip examination to evaluate.

Bronchiolitis obliterans is a chronic disease in which a persistent inflammatory process leads to obliteration of the small airways. Pulmonary function tests (body plethysmography with DLCO, lung clearance index) are performed and the fraction of exhaled nitric oxide is measured. A blood test is following to determine the inflammatory status und collect miRNA. Induced Sputum will be obtained.

Assisted Reproduction Technologies (ART) are increasingly being used worldwide as a result of fertility decline likely caused by changes in both environment and social behaviour. Considering this large usage, it is important to evaluate the potential risk on the health of children conceived using ART. According to the literature, children born after ART are more likely to be at higher risk of health problems than spontaneously conceived ones. Interestingly, recent studies suggested an increase of asthma prevalence in children conceived using In Vitro Fertilization (IVF). The purpose of this study is to evaluate the prevalence of asthma in school adolescents from a cohort of children born after In Vitro Fertilization (IVF), aged 11-15 years as compared to a control group composed of the same age range spontaneously conceived individuals. The expected outcome of this study will provide new information regarding these children to ART professionals of and to their own families, by focusing on an age range (between 11 and 15 years) for which very little information is available to date.

To estimate prevalence of chronic obstructive pulmonary disease (COPD) in cardiac surgery population and establish links between COPD status, as assessed through pulmonary functional tests, and 2-year mortality

To study activity in the reward-circuitry of the brain in patients suffering from cachexia induced by cancer or chronic disease.

The aim of this study is the feasibility assessment of a simple and affordable model for the quantification of Pleural Effusion through thoracic Ultra Sounds images. Two US scans will be performed to measure: the height of Pleural Effusion column (hPEUS) and the area of the effusion in correspondence of the midline of hPEUS (aPEUS). The proposed model will estimate the Pleural effusion volume (PEVUS) by multiplying hPEUS and aPEUS. PEVUS will be compared with volumes estimated by CT scans (PEVCT), obtained within 24h from the US examination.

Obstructive sleep apnea is often associated with microarousals and a stimulation of the sympathetic nervous system. The knowledge of this autonomic activation may help understanding the increase of cardiac risk observed in elderly. The aim of the study is to evaluate the relationship between obstructive sleep apnea severity, age, gender and heart rate response associated with obstructive sleep apnea. Drug-free patients diagnosed with obstructive sleep apneas were included. Clinical data and 24-h polysomnography recordings were analyzed.

The use of cardiopulmonary bypass (CPB) combined with one lung ventilation (OLV) allows to perform minimally invasive cardiac surgery (MICS) through small incisions. MICS is described to be associated with similar outcomes compared with conventional surgery. Although less invasive, MICS has not been reported to favorably impact the incidence of respiratory failure after surgery. The combination CPB and OLV may induce acute respiratory distress syndrome (ARDS). After CPB contact of blood components with the artificial surface of the bypass, lung ischemia reperfusion injury (LIRI) and operative trauma may trigger a systemic inflammatory response syndrome (SIRS). During OLV, ARDS can result from hyperoxia, hyperperfusion and ventilatory distress in the ventilated lung as well as from LIRI and operative trauma of the collapsed lung. Extravascular lung water (EVLW) includes all fluids in the lung except for those in the vascular compartment. An excess of EVLW may lead to respiratory insufficiency. This may be due to an increased hydrostatic intravascular pressure, as it occurs in cardiogenic pulmonary edema, and/or by an increase of lung endothelial and epithelial permeability, as in ARDS. The extravascular lung water index (EVLWI) assessed by the transpulmonary thermodilution technique may be a useful tool for accurate diagnosis of ARDS, and the pulmonary vascular permeability index (PVPI) may help in the differentiation between pulmonary edema due to an increase in the pulmonary capillary permeability versus an increase in the pulmonary capillary hydrostatic pressure. As both CPB and OLV may induce an excess of EVLW, the investigators hypothesize that patients after MICS with intraoperative combination of CPB and OLV may have higher EVLWI and PVPI than those who received either CPB or OLV alone.
