Abstract
PURPOSE: We used next-generation, state-of-the-art, culture independent methodology to survey urine microbiota of males with urologic chronic pelvic pain syndrome and control participants enrolled in the MAPP Network to investigate a possible microbial etiology. MATERIALS AND METHODS: Male patients with urologic chronic pelvic pain syndrome and matched controls were asked to provide initial, midstream and post-prostatic massage urine specimens. Specimens were analyzed with Ibis T-5000 Universal Biosensor technology to provide comprehensive identification of bacterial and select fungal species. Differences between urologic chronic pelvic pain syndrome and control study participants for the presence of species or species variation in a higher taxonomic grouping (genus) were evaluated using permutational multivariate analysis of variance and logistic regression. RESULTS: Initial and midstream urine specimens were obtained from 110 (post-prostatic massage urine in 67) participants with urologic chronic pelvic pain syndrome and 115 (post-prostatic massage urine in 62) controls. Overall 78, 73 and 54 species (42, 39 and 27 genera) were detected in initial, midstream and post-prostatic massage urine specimens, respectively. Mean (SD) initial, midstream and post-prostatic massage urine species count per person was 1.62 (1.28), 1.38 (1.36) and 1.33 (1.24) for cases, and 1.75 (1.32), 1.23 (1.15) and 1.56 (0.97) for controls, respectively. Overall species and genus composition differed significantly between participants with urologic chronic pelvic pain syndrome and controls in initial stream urine (p=0.002 species level, p=0.004 genus level), with Burkholderia cenocepacia overrepresented in urologic chronic pelvic pain syndrome. No significant differences were observed at any level in midstream or post-prostatic massage urine samples. CONCLUSIONS: Assessment of baseline culture-independent microbiological data from male subjects enrolled in the MAPP Network has identified overrepresentation of B. cenocepacia in urologic chronic pelvic pain syndrome. Future studies are planned to further evaluate microbiota associations with variable and changing urologic chronic pelvic pain syndrome symptom patterns.

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 it
