Task: Intent Identification
Input (English): Activated protein C (APC) is a plasma serine protease with systemic anticoagulant and a wide spectrum of cytoprotective activities that has been proposed as a promising therapy for acute stroke. Therefore, we sought to investigate the role of endogenous APC in human ischemic stroke.', 'Our target were 119 consecutive patients with an ischemic stroke involving the middle cerebral artery territory who received tissue plasminogen activator (t-PA) within 3 h of symptom onset. APC was measured before, as well as 1 and 2 h after t-PA administration, and again at 12 and 24 h after stroke onset. Cranial tomography scan was obtained at admission and repeated at 24-48 h or when a neurological worsening occurred to rule out the presence of hemorrhagic complications. The functional outcome was evaluated by 3-month modified Rankin Scale.', 'A total of 117 t-PA-treated patients were finally included in the analyses. APC peaked at 1 h after t-PA administration (pretreatment APC = 132.44 +/- 36.39%, 1-hour APC = 184.20 +/- 34.28%, 2-hour APC = 145.50 +/- 35.23%; p < 0.0001). Interestingly, a high 2-hour APC level was associated with parenchymal hemorrhages (OR = 25.19; 95% CI = 4.76-133.19; p = 0.0001) and mortality (OR = 13.8; 95% CI = 2.58-73.63; p = 0.001), in a logistic regression model. Our results remained significant after Bonferroni correction for multiple testing.
