Early Fesoterodine Fumarate Administration Prevents Neurogenic Detrusor Overactivity in a Spinal Cord Transected Rat Model
Bibliographic record
Abstract
BACKGROUND: In spinal cord injury, onset of detrusor overactivity (DO) is detrimental for quality of life (incontinence) and renal risk. Prevention has only been achieved with complex sophisticated electrical neuromodulation techniques. PURPOSE: To assess the efficacy of early fesoterodine fumarate (FF) administration in preventing bladder overactivity in a spinal cord transected (SCT) rat model. METHODS: 33 Sprague-Dawley rats were allocated to 6 groups-Group 1: 3 normal controls; Group 2: 6 SCT controls; Group 3: 6 SCT rats + FF 0.18 mg/kg/d; Group 4: 6 SCT rats + FF 0.12 mg/kg/d; Group 5: 6 SCT rats + FF 0.18 mg/kg/d + 72-h wash-out period; Group 6: 6 SCT rats + FF 0.12 mg/kg/d + 72-h wash-out period. SCT was performed at T10. FF was continuously administered. Cystometry was undertaken 6 weeks after SCT in awake rats recording intermicturition pressure (IMP), baseline pressure, threshold pressure (Pthres) and maximum pressure (Pmax). Normal controls and SCT controls were initially compared using the Mann-Whitney U tests in order to confirm the SCT effect on cystometric parameters. The comparisons in cystometric and metabolic cage parameters between SCT controls and treated rats were done using post-hoc Dunn's tests for Kruskal-Wallis analysis. Statistical testing was conducted at the two-tailed α-level of 0.05. RESULTS: Pressure parameters were significantly higher in SCT control group compared to normal controls. Six weeks after SCT, IMP was significantly lower in low dose treated group than in SCT controls. Pmax was significantly lower in 3 treated groups compared to SCT controls. Pthres was significantly lower in full time treated groups than in SCT controls. CONCLUSION: Early administration of FF modulates bladder overactivity in a SCT rat model. Whereas short-term prevention has been demonstrated, the long-term should be further analyzed. Clinical application of these results should confirm this finding through randomized research protocols.

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.
