P332 Mindfulness-based stress reduction and cognitive intervention improve the health-related quality-of-life and ability to work in Crohn’s disease patients: A randomised controlled trial
Bibliographic record
Abstract
Abstract Background Crohn’s disease (CD) patients have reduced quality-of-life (QoL) in physical, emotional and social domains, and diminished work and leisure activities. We examined whether Mindfulness-Based Stress Reduction and Cognitive Intervention (‘Intervention’) can improve QoL and ability to work. Methods Patients (≥18 years), Harvey–Bradshaw Index (HBI) >4 and <16, were randomised to Intervention or Control groups. Intervention was taught in 8 weekly sessions by social workers via SKYPETM with twice-daily practice and back-report required. Medications were not controlled. HBI was completed at entry (T1) and 12 weeks (T2), and these questionnaires: (1) Short inflammatory bowel disease questionnaire (SIBDQ), disease-specific HRQoL measure. (2) Short-Form 12 (SF-12) questionnaire, generic HRQoL measure of physical health (PH) and mental health (MH). (3) EQ-5D-3L HRQoL questionnaire. (4) Work Productivity and Activity Impairment (WPAI) questionnaire, measuring absenteeism, presenteeism (reduced productivity), work impairment (composite of absenteeism and presenteeism), and leisure activity impairment. Statistics: Pearson Chi-squared, Wilcoxon signed-rank test. Results There were 39 Intervention and 43 Control patients. Demographic and medical characteristics (median, %) were: age 30 y; women 65%, married/partner 48%; higher education 83%; BMI 22; non- or past-smokers 92%; disease duration 5 y; HBI 8 (range 5–15); past surgery 17%; Montreal A2 89%, L2+L3 89%, B1+B2 89%, perianal disease 18%; drugs: corticosteroids 4%, 5-ASA 5%, immunomodulators 21%, biologics 43%; (p = ns between groups). Socio-economic status was higher in Intervention (87% = good/very good) than Control (58%, p = 0.016). HBI, SIBDQ and SF PH improved in both groups, but SF MH, EQ-5D-3L and all WPAI measures improved only in Intervention group (Table). Non-significance of WPAI indices between groups resulted from small sample size. Conclusion Mindfulness-Based Stress Reduction and Cognitive Intervention led to increased QoL and less work and activity impairment. If confirmed in a large cohort the intervention may be offered to all CD patients.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
