TL;DR: In this paper, the authors suggest that vitamin D may have an immunological role in Crohn's disease (CD) and ulcerative colitis (UC) and that there is a weak association between vitamin D status and disease activity but have significant limitations.

TL;DR: Inclusion of narrative concepts identified using natural language processing improves the accuracy of electronic medical records case definition for CD and UC while simultaneously identifying more subjects compared with models using codified data alone.

TL;DR: A data-normalization platform that ensures data security, end-to-end connectivity, and reliable data flow within and across institutions is developed and demonstrated by executing a QDM-based MU quality measure that determines the percentage of patients between 18 and 75 years with diabetes whose most recent low-density cholesterol test result during the measurement year was <100 mg/dL.

TL;DR: In this article, the authors developed a robust electronic medical record-based model for classification of inflammatory bowel disease leveraging the combination of codified data and information from clinical text notes using natural language processing.

TL;DR: Psychiatric co‐morbidity, in particular major depression and anxiety, is common in patients with Crohn's disease and ulcerative colitis and prior studies examining this may be confounded by the co‐existence of functional bowel symptoms.
