Comparison of the 1-min Sit-to-Stand Test to the 6-minute Walk Test in the Respiratory Functional Assessment of Pulmonary Fibrosis
Fibrosing interstitial lung diseases or pulmonary fibrosis represent a heterogeneous group of progressive pulmonary pathologies, responsible for a significant morbi-mortality. They are defined by an infiltration of the pulmonary interstitium associating in a variable way an inflammatory component (deposit of inflammatory cells) and a fibrosing component (deposit of collagen). Idiopathic pulmonary fibrosis (IPF) is the most common and most severe pulmonary fibrosis. Other pulmonary fibroses are mainly represented by non-specific interstitial lung disease, pulmonary fibroses associated with connectivites, hypersensitivity pneumonitis, ...

Controls for Respiratory Diseases
This is the registry of control participants for patients with various respiratory diseases. We screened healthy volunteers who visited Seoul National Hospital Healthcare System Gangnam Center for routine health check-up, and enrolled patients who agree to participate in the study. The participants undergo baseline questionnaires, provide blood specimen and information of the results of health check-up. We will include participants as controls if they have no significant respiratory symptom and no significant radiographic abnormality. The data from this registry will be compared with those from other registry of various respiratory...

Cystic Fibrosis and Fit-to-Fly
Due to the hypobaric hypoxia during air travel, some patients with Cystic Fibrosis (CF) need supplemental oxygen during air travel. The study aims to evaluate if adding exercise desaturation to the pre-flight evaluation will help predict requirements for in-flight supplemental oxygen.

Database and Biobank of Patients With Hypersensitivity Pneumonitis
Sub-study of the main Pulmonary Fibrosis Biomarker (PFBIO) cohort (NCT02755441), recruiting patients with an MDT-diagnosis of hypersensitivity pneumonitis (HP). Patients are included for the collection of blood samples and regular clinical data. The database and biobank will be available for studies of HP, and can be directly compared to the main PFBIO cohort, which has recruited patients with Idiopathic pulmonary Fibrosis (IPF) since 2016. Biomarkers will be assessed as diagnostic and prognostic. Further subtyping of HP, based on blood markers (including precipitins) will also be possible with the PFBIO-HP project.

Detection of Early Idiopathic Pulmonary Fibrosis
The purpose of the study is to determine if miR200 family may serve as a biomarker of IPF.

Detection of Integrin avb6 in IPF, PSC, and COVID19 Using PET/CT
Detection of Integrin avb6 in Idiopathic Pulmonary Fibrosis, Primary Sclerosing Cholangitis, and Coronavirus Disease 2019 with [18F]FP-R01-MG-F2 with PET/CT

Detection of Unsuspected Small Airways Obstruction in Cystic Fibrosis
Goal is to physiologically detect unsuspected small airways obstruction in children and adults with treated heterozygous and homozygous cystic fibrosis. Unsuspected refers to normal routine pre bronchodilator spirometry including normal FEV1(L), FVC (L). and FEV1/FVC%. This is a retrospective study.

Developing Optimal Parameters for Hyperpolarized Noble Gas and Inert Fluorinated Gas MRI of Lung Disorders
The goal of this research is to optimize the MRI system to obtain ideal lung images using Hyperpolarized (HP) Noble and Inert Fluorinated Gases as contrast agents. Lung coils tuned to the frequencies of these gases will be used. This study will take place at TBRHSC in the Cardiorespiratory Department and in the Research MRI facility.

Diagnostic Value of KL-6 in ILD
KL-6 may be a useful biomarker in patients with interstitial lung disease, but there is limited information in non-Asian populations. Therefore, it is necessary to carry out studies in other populations to confirm the diagnostic values of the biomarker and its prognostic implication. Hypothesis KL-6 may be a useful biomarker in the management of interstitial lung diseases. But it is necessary to know more about its utility in the European population. Study Objectives: - To determine the concentration of KL-6 in serum of patients with pulmonary fibrosis at the time of diagnosis compared to patients without...

Digital App for Telerehabilitation in Respiratory Diseases
The purpose of this study is to evaluate the feasibility and the mid-term effects of a pulmonary rehabilitation intervention, delivered by digital App, on quality of life of patients affected by respiratory diseases. The App will include a monitored exercise training program based on most recent cardiopulmonary rehabilitation guidelines, including alerts, reminders and educational contents as well as chat and online visits with healthcare professionals to improve patient engagement.
