Active clinical trials for "Lung Diseases"

The I-FILE study is a prospective multicenter, multinational observational study where the feasibility of a patient-led registry using home monitoring in patients with pulmonary fibrosis will be evaluated. The aim of the study is to gain more insights in disease behavior in patients with pulmonary fibrosis, so in future patients with progressive disease can be better identified.

To evaluate the accuracy of chest ultrasound for diagnosis of different lung lesions in comparison to the gold standard among children.

This study aims to assess the clinical presentation, radiological patterns and outcome of COVID-19 infection in patients with chronic pulmonary disease. Inter-relationship between the severity of COVID-19 infection and chronic pulmonary diseases.

This panel study aims to evaluate the effects of air pollutants on cardiopulmonary health of patients with chronic obstructive pulmonary disease (COPD) and explore the potential biological mechanisms.

Chronic obstructive pulmonary disease (COPD) exacerbation is a major cause of physician visits and hospital admissions associated with acute respiratory failure, causing increased morbidity and premature mortality and thus it can significantly affect Health Related Quality of Life (HRQoL). Previous studies suggested that patients who have experienced frequent exacerbation present worse HRQoL compared to patients with infrequent exacerbations. However, there are still questions regarding the relationship between HRQoL and exacerbations. In the present study the investigators will study a cohort of COPD patients over 6 years, they will document exacerbations, they will assess lung emphysema by computed tomography of the chest and they will evaluate health related quality of life in COPD patients. The investigators hypothesize that the extend of emphysema in COPD patients is positively correlated with worsen Health related quality of life (HRQoL).

Abstract Chronic obstructive pulmonary disease (COPD) is the fourth leading cause of death in Canada. COPD is not just a disease of men, nor is it solely a disease in old age. Women have been underrepresented and early disease has not been studied. Underdiagnosis of COPD remains a significant problem, and it may indicate an unmet healthcare need. This can potentially results not only in a patient been misinformed, but can lead to incorrect management. Epidemiological research is needed to develop a framework to combat this major health problem, by better characterization of the population of men and women at risk and patients with early disease, by better understanding which factors modifiable through health interventions are related to health perception (health-related quality of life) and disease evolution. This will be possible through a nationwide study, the Canadian Cohort Obstructive Lung disease (CanCOLD), a prospective longitudinal study. The CanCOLD study is built on the current ongoing prevalence nationwide study, the Canadian Obstructive Lung disease "COLD" study. The CanCOLD will be the first study to assess prevalence of disease across Canada and its consequence in men and women, and to evaluate a conceptual model of disease severity based on patient's health perception (health-related quality of life). Ultimately, this project will extend to a longitudinal follow up (3 years or beyond) and will allow to have a better understanding of the lifestyle risk factors, not only smoking but also diet, physical activity, and co morbid conditions. This will be a great asset to shift from management of a single risk factor (tobacco control) to total COPD risk management. The results of the study will greatly help to assist decision makers in developing policies to improve the diagnosis, the management of COPD and to optimize health care services use.

The purpose of the study is to determine whether the excretion of renal water- and salt-channels in the urine reflects the handling of water and salt in the kidneys, and whether the excretion can be used to monitor and/or predict the effects of treatment of certain heart or lung diseases.

This is a study designed to measure, characterize and describe changes on pulse-oxymetry values produced as a result of deep breaths in patients with stable chronic hypoxemic respiratory failure.

A post-market study to assess the performance and safety of a RF ablation catheter to bronchoscopically ablate lung lesions will be evaluated in patients with confirmed diagnosis of non-small cell lung cancer or metastatic lung lesions who are scheduled for surgical resection.

The aim of this study is to evaluate the effects of a three-week inpatient pulmonary rehabilitation (PR) program on the walking speed in patients with chronic obstructive (COPD) or interstitial lung disease (ILD).
