Canadian researcher Don Sin of St. Paul's Hospital, Providence Health Care is working to help people like Vivianne Toupin, who has chronic obstructive pulmonary disease (COPD), a disease that damages the airways and air sacs of the lungs, making it hard to breathe. Sin is leading a multimillion-dollar program within the Center of Excellence for Prevention of Organ Failure (PROOF Center) to discover and develop biomarker blood tests to help clinicians diagnose the disease and predict which COPD patients will experience life-threatening lung attacks. The biomarkers will help doctors to guide therapy after diagnosis. More in Hospital News
