Abstract

fetched live from OpenAlex

The objective of this study was to evaluate long-term health-related quality of life outcomes among patients who had a colectomy within the previous 10 years. A cross-sectional survey was administered to consecutive patients ≥18 years of age with ulcerative colitis who had a colectomy within the last 10 years from centers in Canada, Australia, and the United Kingdom. Data were extracted from medical chart reviews to confirm selected self-reported patient characteristics. Of 351 survey respondents, 49 % were male and the median age was 40 years (interquartile range 30-52). Respondents were diagnosed with UC a median of 9.2 (5.7-15.1) years prior to the survey and first surgery occurred a median of 3.7 (2.1-5.8) years ago. Although most respondents (84 %) reported improved quality of life compared to the status before surgery, 81 % experienced problems in at least one of the following areas: depression, work productivity, restrictions in diet, body image, and sexual function. According to HADS scores, 30 and 17 % of survey respondents experienced anxiety and depression, respectively. Among moderate to severe UC patients pre-colectomy, 27 % of men and 28 % of women reported that their sexual life was worse now than before surgery. The mean EQ-5D utility index score overall was 0.79 (95 % confidence interval 0.77-0.81). Quality of life after colectomy for UC is generally good, but there are persistent quality of life issues that impact multiple domains, including psychological and sexual functioning.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
