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

This study will investigate the prevalence of chronic obstructive pulmonary disease (COPD) in patients who are newly diagnosed with lung cancer and compare it to the prevalence of COPD in controls recruited from a smoking cessation clinic.

Investigators examine blood-pressure variance, several cardiovascular risk factors of patient with epistaxis. As a result of collected data, investigators look into correlation between epistaxis and hypertensive cardiovascular disorder.

Rationale: With 1.6 million new cases diagnosed each year and 1.3 million deaths, lung cancer is the leading cancer-related death worldwide and it represents a pressing health issue. Patients with lung cancer are more likely to experience cachexia, a severe debilitating disorder causing fatigue, weight loss, muscle wasting and associated with reduced physical function, increased chemotherapy toxicity and reduced survival. This syndrome occurring in about 80% of advanced cancer patients is the direct cause of death in about 20% of cases. However, despite the importance of cachexia in lung cancer, its mechanisms ans its relation with muscle function and effort tolerance are still unknown. Aim: To explore muscle function, signaling pathways and its relationship to impaired functional capacity of patients with non-small-cell lung cancer(NSCLC); depending of whether they have cachexic state at diagnosis. Methods: This study will be conducted at the Institut universitaire de cardiologie et de pneumologie de Québec. 56 patients newly diagnosed of NSCLC will be recruited and separated whether or not they have a cachexic state. The evaluation will need two visits separated by 5 days. During the evaluation the following tests will be done: Anthropometric measures Level of daily physical activity Pulmonary function test Maximal incremental cardiopulmonary exercise test on ergocycle Endurance test on ergocycle Muscle function tests Magnetic stimulation Quadriceps biopsy

For patient in intensive care unit, extubation failure is defined as the necessity of early reintubation after scheduled extubation, with Increased morbidity and mortality, so it seems important to quickly identify patients with high risk of post-extubation acute respiratory failure. Major post-extubation laryngeal edema is one of extubation failure causes, and its incidence vary in literature from 4 to 37%. We can't currently predict arising of a major post-extubation laryngeal edema. However, a recent pilot study showed that laryngeal ultrasonography could help to identify patients with high risk of post-extubation stridor, measuring ultrasonic leak volume and cuff-deflated air-column width, of which we propose to assess diagnostic performance.

The goal of this study is assess the quality of life of advanced non-small cell lung cancer (NSCLC) patients who are undergoing first-line chemotherapy, analyze the current status and tendency of quality of life (QOL). The method is to use the Functional Assessment of Cancer Therapy-Lung (FACT-L) scales, assess the quality of life before the chemotherapy, after 1st cycle of chemotherapy and after 2nd cycle. After 3 time-points, investigators analyze all the subscales and constructs of FACT-L. The assumption is the quality of life will be better after 2 cycle of chemotherapy.

Surgery for malignant pleural mesothelioma is complex and prolonged, and may involve significant blood loss with considerable blood and product transfusion. Thromboelastography (TEG) is a global assay of coagulation that uses whole blood to produce a tracing that records kinetic changes in clot formation. This study aims provide a better understanding of the coagulation profile of these patients, and will form the basis of a TEG-based transfusion algorithm for future surgeries for mesothelioma.

Prevalence of sleep-related breath disturbance in patients in cardiac rehabilitation. The aim of the register is to enable a better diagnosis and early treatment initiation in the context of secondary prevention. In addition to the prevalence, the further course of the patients shall be documented after hospital discharge to verify any gaps (sleep laboratory, therapy introduction) and emphasize the importance of rehabilitation and to examine the possibility of initiating therapy in rehabilitation.

Increased intra-abdominal pressure (IAP) affects pulmonary dynamics. However, little is studied whether pulmonary dynamics affects IAP. We hypothesize that the change of IAP can also reflect the change of pulmonary dynamics. In this study, we choose patients who received spontaneous breathing trial to answer the hypothesis.

To compare the time to pathogen eradication, and the relationship to the time to clinical improvement, between ceftaroline and case-matched vancomycin treated controls in the treatment of adults with serious infections caused by Methicillin-Resistant Staphylococcus aureus (MRSA).

The pathogenesis of idiopathic pulmonary fibrosis (IPF) is debatable. Looking for an insult to lung parenchyma that generates the pathogenesis of the disease is challenging. Pepsin is a proteolytic enzyme present in the gastric juice. Microaspirations of gastric content were described as a potential factor for injury in many chronic lung disorders. Bronchoalveolar lavage (BAL) is a routine investigation technique in interstitial lung diseases. The presence of pepsin in the BAL fluid recovered from patients with IPF may indicate a possible role for gastric microaspirations in the pathogenesis of the disease.
