Active clinical trials for "Lung Diseases"

The primary objectives of the study are to use US and UK data to describe the characteristics of Chronic Obstructive Pulmonary Disease (COPD) patients according to various demographic, lifestyle, clinical, and medication use.

The purpose of this study is to investigate the clinical features and long-term outcome of anti-neutrophil cytoplasmic antibody (ANCA)-positive interstitial lung disease (ILD) and assess the difference between microscopic polyangiitis (MPA) associated ILD and isolated ANCA-positive idiopathic interstitial pneumonia.

The intention with the study is to have a better understanding of what happens to COPD patients' symptoms, lung function and markers of inflammation over 12 weeks. This information will increase the understanding of COPD and how to design new treatments for COPD in the future.

Although some important progresses were made in the field of the meridian research, no breakthroughs have been achieved. Besides,there are some problems in meridian researches. Particularly, previous research of meridian phenomenon involved lots of subjective elements and outcomes.Researches that use modern scientific techniques to investigate the biological characteristics of meridians are urgently needed. Therefore, this study is designed to assess the metabolic characteristics of the Heart and Lung meridians by using functional near infrared spectroscopy. Thus, the biological characteristics of meridians could be presented objectively in a scientific methodology.

A retrospective analysis study in COPD patients for an exact follow-up period of 12 months (in subgroup analyses: 24 and 36 months); censoring of patients will only be done in case a patient died during the respective follow-up period.

Secondary data analysis will be performed as our approach to complete the study. A nationally representative dataset (BRFSS, 2017) will be used to answer the above hypotheses.

The purpose of this study is determine the prevalence of undiagnosed Chronic Obstructive Pulmonary Disease (COPD) in population served and with exposure to cigarettes in the Region of Murcia

This is a cross-sectional validation study, designed to evaluate the discriminative validity of the Chronic Obstructive Pulmonary Disease Assessment Test translated in a local language in patients with Chronic Obstructive Pulmonary Disease.

Alpha-1 antitrypsin deficiency (AATD) is considered a rare genetic cause of chronic obstructive pulmonary disease (COPD) and liver disease. Recent data has suggested that AATD is not as rare as originally thought and undetected AATD may account for COPD in some patients. This study was designed to evaluate the frequency of undetected AATD in a population reporting to academic pulmonary function testing facilities who meet criteria for the diagnosis of COPD. All individuals meeting GOLD criteria for COPD will be consented and offered free testing for AATD. The results will help identify the percent of those with COPD who have undetected AATD.

The purpose of this study is to determine the prevalence of pulmonary embolism in our population of Chronic Obstructive Pulmonary Disease (COPD) patients admitted to hospital with dyspnea. The patients will undergo investigation for pulmonary embolism, according to current guidelines.
