خلاصه	The West Haven Criteria are the standard for grading hepatic encephalopathy (HE) severity, ranging from subclinical (Grade 0) to deep coma (Grade 4). Developed by Trey and Davidson in the 1960s and refined by the West Haven group, these criteria integrate mental status changes (confusion, asterixis, disorientation) and consciousness level to stage HE. The West Haven grade is a strong predictor of short-term prognosis in cirrhosis and guides urgency of intervention (lactulose, rifaxomicin, mannitol, intubation).	The Mayo Score is a validated tool for assessing disease activity in ulcerative colitis, integrating clinical symptoms and endoscopic findings. Introduced by Schroeder and colleagues in 1987, it has become the reference standard for UC activity assessment in clinical trials and practice. The score combines stool frequency, rectal bleeding, overall physician global assessment, and endoscopic subscore into a single 0–12 scale.
