Exploring Novel Biomarkers for Emphysema Detection

This study is looking for new markers in speech and breathing patterns that could help detect emphysema (a type of lung damage) earlier and more accurately. Researchers will analyze speech recordings and breathing tests to see if they can identify signs of emphysema without invasive tests. **You may be eligible if...** - You are an adult over 18 years old - You have current breathing symptoms such as shortness of breath, cough, or mucus production - You have confirmed airflow obstruction on a breathing test or emphysema signs on a CT scan - You have risk factors for COPD (such as a history of smoking) - You have had a chest CT scan within the past 12 months - You can read, write, and understand Dutch **You may NOT be eligible if...** - You had a COPD flare-up in the past 8 weeks - You have conditions that affect speech or breathing (e.g., severe heart failure, Parkinson's disease, neuromuscular disease, BMI over 40) - You have asthma or cystic fibrosis - You have had part of a lung surgically removed or had a lung volume reduction procedure - You are participating in another interventional study Talk to your doctor to see if this trial is right for you.
