Active clinical trials for "Lung Diseases"

The purpose of this study is to examine genetic factors that influence the development of chronic obstructive pulmonary disease (COPD) in Hispanics, a minority group at high risk for the disease.

The purpose of the LINQ™ for COPD study is to characterize Reveal LINQ™ derived data from patients with COPD by assessing the relationship between changes in LINQ™ derived data with COPD exacerbation events.

Investigators will perform this study to validate shuttle walking tests in korean patients with chronic obstructive pulmonary disease. This study will be performed as multi-center prospective observational correlation study in ulsan university hospital and asan medical center. 36 participants will perform the exercise stress test with cycle, 6 minutes walking test and shuttle walking test. Investigators will analyze correlation 6 minutes walking test and shuttle walking test with exercise stress test.

To investigate the ability of machine learning models based on radiomic features extracted from thin-section CT images to differentiate IPF patients from non-IPF interstitial lung diseases.

The study of the diaphragm is an important point in the assessment of COPD patients. Ultrasonographic evaluation of the diaphragm is considered a simple, non-invasive, available bedside technique. Ultrasonography can be used for evaluation of the site, structure, and motion of the diaphragm, assessment of excursion, and thickness. The aim of the study is ultrasonographic assessment of the diaphragm in COPD patients and its relation to disease severity

Whole-body plethysmography (WBP) is the gold standard for measuring lung volume, but its clinical application is limited because it requires expensive equipment and is complicated to use. Studies have shown that the single-breath helium dilution (SBHD) method, which is commonly used in clinical practice, significantly underestimates lung volume in patients with obstructive lung disease (OLD). Therefore, by comparing the differences in lung volume measured by the SBHD method and WBP in patients with different severities of obstructive lung disease, we aim to establish a correction equation for the SBHD method to determine the total lung volume in obstructive lung disease patients.

This study evaluates whether structured self-monitoring (SSM) by a symptom checklist in combination with a pulse oximeter worn at the wrist allows lowlanders with COPD to accurately identify whether or not they will experience an altitude-related illness during altitude travel.

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 meridian phenomenon are urgently needed. Therefore, this study is designed to assess the heat transport characteristics of meridian phenomenon for the Heart and Lung meridians by using infrared thermography. Thus, the biological characteristics of meridian phenomenon could be presented objectively in a scientific methodology.

Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory disease of the airways and lungs that develops against harmful particles or gases with exacerbations. Coexistence of bronchiectasis with COPD may lead to worsening of the functional parameters as well as alteration of the microbiological pattern in exacerbations and may negatively affect the exacerbation result parameters.

Open-label comparative multicentric cohort study in COPD patients with LABA/ICS, switched to either tiotropium/olodaterol and observed for 12 weeks approximately.
