Childhood bladder and bowel dysfunction predicts irritable bowel syndrome phenotype in adult interstitial cystitis/bladder pain syndrome patients
Bibliographic record
Abstract
INTRODUCTION: Many clinicians have suggested that a history of bladder and bowel dysfunction (BBD) in childhood predisposes to the development of interstitial cystitis/bladder pain syndrome (IC/BPS) or irritable bowel syndrome (IBS) in adulthood. We hypothesized that BBD symptoms in childhood would predict the IBS-associated phenotype in adult IC/BPS patients. METHODS: Consecutive female patients (n=190) with a diagnosis of IC/BPS were administered a modified form of a clinical BBD questionnaire (BBDQ) to capture childhood BBD-like symptoms, as well as Interstitial Cystitis Symptoms Index (ICSI), Interstitial Cystitis Problem Index (ICPI), Pelvic Pain and Urgency/Frequency (PUF) questionnaires and UPOINT categorization. Patients were stratified to IBS-positive or IBS-negative according to clinical assessment of IBS-like symptoms. RESULTS: The 127 patients (67%) identified with IBS-like symptoms recalled significantly higher BBDQ scores than the 63 patients (33%) who were IBS-negative (2.8 vs. 2.3; p=0.05). The IBS-positive patients also reported a higher number of UPOINT domains than their non-IBS counterparts (3.8 vs. 2.9; p=0.0001), while their PUF total scores were significantly higher (13.6 vs. 12.3; p=0.04). IBS-positive patients more often recalled that in childhood they did not have a daily bowel movement (BM) (p=0.04) and had "to push for a BM" (p=0.009). In childhood, they "urinated only once or twice per day" (p=0.03) and recalled "painful urination" more than those without IBS (p=0.03). There were no significant differences between the groups in answers to the other five questions of the BBDQ. CONCLUSIONS: Our symptom recollection survey was able to predict the IBS phenotype of IC/BPS based on a childhood BBDQ. Further prospective studies are needed to further evaluate these novel findings.

Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
