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

The primary aim of this non interventional study is to assess the independent prognostic role on overall survival of primary tumour 18F-FDG uptake value (SUVmax) measured on 18fluorodeoxyglucose positron emission tomography (18F-FDG-PET) in patients with non-metastatic non-small cell lung cancers treated with curative intent, taking into account the other conventional prognostic factors (performance status, age, sex, disease stage).

Disease related biomarkers have been established decades ago, e.g. blood glucose for diabetes diagnosis and management. Their discovery has grown dramatically during the past decade and they have the potential to lead the physician in diagnosis -especially differential diagnosis - and therapy. However, a specific serum-biomarker in lung diseases has not been established. Aim of the current study is to to measure lung specific proteins in the serum in patients with various lung diseases and to correlate those with disease severity, lung function and other laboratory results

Recently it has been suggested that specific mutations in the EGFR gene in lung cancer patients is associated with response to a novel drug targeting the EGF system. Recent research also indicates that there is a possible association to the degree of aggressiveness of the disease. The importance of these mutations is controversial, because the data are based on small studies with highly selected patients. In this project the investigators want to study the types and frequencies of EGFR mutations in both untreated and treated patients in a systematic manner and relate this to survival. The thorough registration of patient data in DK enables us to create a strong The investigators expect this knowledge to be of greatest importance for future rational use of drugs targeting the EGF receptors.

The purpose of this prospective cohort study is to determine factors involved in survival in new COPD patients treated by long-term oxygen therapy. Background: long-term oxygen therapy is indicated in patients with severe COPD. No studies have been performed in the past 20-25 years to examine the results of early clinical trials. Further studies are necessary to understand the utility of oxygen therapy in severe COPD.

A questionnaire will be used in order to find out the reasons for poor adherence for long-term treatment in children with asthma. The hypotheses is maternal factors including the knowledge that asthma is a chronic disease and fear to administer inhaled steroids are major obstacles for appropriate adherence.

The aim of this study is to 1-evaluate subjectively by questionnaires and objectively by ambulatory actigraphy the quality of sleep in patients with newly diagnosed lung cancer; 2- to correlate sleep quality index with quality of life, daytime alertness, Performans status and lung cancer staging at diagnosis.

Hypothesis:benefits of inspiratory muscle strenght training with Respifit S decreases symptoms, disability or handicap of patients affected by COPD. The inspiratory fraction (inspiratory capacity IC/ total lung capacity TLC)may be functionally more representative than other traditional indices.

Patients with hemolytic disorders (e.g. sickle cell anemia or thalassemia) are known to develop pulmonary hypertension. Hemolysis is where red blood cells are destroyed and their contents released into the circulation. It is thought that these red-cell contents cause constriction and thrombosis of the blood vessels in the lungs. Conversely, it is possible that patients with pulmonary hypertension have hemolysis. In this study we will be drawing blood from a range of patients and normal controls for a panel of blood tests related to hemolysis.

To evaluate the correlation between SERPIN D1 expression in clinical specimen (including surgical specimen and blood sample) and lung cancer metastasis.

This is a study of the lung health of the population of Vancouver and the extent of, and the risk factors for, chronic obstructive lung disease.
