Abstract

fetched live from OpenAlex

Abstract Background Inflammatory bowel disease (IBD) is a chronic inflammatory disease of the gut and includes predominantly Crohn’s disease (CD) and ulcerative colitis (UC). The Inflammatory Bowel Disease Symptom Inventory (IBDSI), developed at the University of Manitoba is a validated patient self-report symptom inventory which has shown to demonstrate good validity to accepted clinician-based assessments of disease activity. The IBDSI focuses of 5 main symptom clusters: bowel symptoms, abdominal discomfort, fatigue, bowel complications, and systemic complications. While there is good evidence for the presence of these symptoms in IBD, there has yet to be an analysis of the correlation between specific symptom clusters and active IBD. Aims Our aim is to identify symptoms experienced by patients with IBD being followed prospectively over one year and further analyze which of these symptoms are correlated with disease activity. Methods 155 patients enrolled in the Manitoba Living with IBD Study were eligible for the current study. Bi-weekly IBDSI short-form survey results were analyzed to determine which IBD-related symptoms were experienced by each patient over the study period (1 year). Descriptive data for symptoms will be reported, and will then be compared to disease activity (defined in Crohn’s disease as an IBDSI score >14 and in UC>13 and fecal calprotectin level (FCAL) >250 ug/g) to determine which symptoms most correlate with active IBD. Results The study population ranged from ages 18–70, with a mean age of 43 years. 30.3% (47) of the population were male. 65.8% (102) of the population consisted of CD, 31.0% (48) had UC, the remaining 3.2% (5) had IBD-type unclassified. Some of the symptoms for analysis will include abdominal pain, frequency and consistency of bowel movements, blood within the stool, and other associated symptoms such as nausea and loss of appetite. The results for the frequency of symptoms reported and which are most correlated with disease activity is still under analysis. Conclusions This will be the first study assessing the association between symptoms experienced by subjects contrasted to disease activity using the self-reported measurement IBDSI and FCAL.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
