A Prospective, Randomized Trial of 3 or 14 Days of Ciprofloxacin Treatment for Acute Urinary Tract Infection in Patients with Spinal Cord Injury
Bibliographic record
Abstract
BACKGROUND: Urinary tract infection (UTI) is common among patients with spinal cord injury. The optimal duration of treatment for symptomatic UTI has not been determined. METHODS: A randomized, double-blind, placebo-controlled trial compared 3-day and 14-day regimens of ciprofloxacin, 250 mg twice daily, for the treatment of acute UTI in patients with spinal cord injury. Patients with pyelonephritis, struvite stones, hydronephrosis, or long-term indwelling catheters were excluded from the trial. RESULTS: Sixty patients with spinal cord injury were enrolled in the trial, with 30 patients assigned to each study arm. The most common infecting organisms were Klebsiella species (30%), Enterococcus species (22%), and Escherichia coli (22%); 33% of the infections were polymicrobial. Microbiological cure at long-term follow-up was significantly better among patients who received therapy for 14 days than among patients who received therapy for 3 days. By 6 weeks of follow-up, microbiological relapse (in 11 [37%] of 30 patients vs. 2 [7%] of 30 patients; 95% confidence interval [CI], 1.38-3.18; P=.01) and symptomatic relapse (in 7 [23%] 30 patients vs. 0 of 30 patients; 95% CI, 1.69-3.13; P=.01) both occurred more frequently in patients treated for 3 days. Reinfection occurred with similar frequency in patients in the 2 study arms. Six of 7 evaluable patients with treatment failure had a fluoroquinolone-resistant organism isolated at enrollment. CONCLUSIONS: For patients with spinal cord injury, treatment of acute symptomatic UTI for 14 days leads to improved clinical and microbiological outcomes, compared with short-course therapy.

How this classification was reachedexpand
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.
