Abstract
IMPORTANCE: Although cephalosporins are the cornerstone of treatment of Neisseria gonorrhoeae infections, cefixime is the only oral antimicrobial option. Increased minimum inhibitory concentrations (MICs) to cefixime have been identified worldwide and have been associated with reports of clinical failure. OBJECTIVE: To assess the risk of clinical treatment failure of N. gonorrhoeae infections associated with the use of cefixime. DESIGN, SETTING, AND POPULATION: A retrospective cohort study of culture-positive N. gonorrhoeae infections at a single sexual health clinic in Toronto, Canada, that routinely performs test of cure. The cohort comprised N. gonorrhoeae culture-positive individuals identified between May 1, 2010, and April 30, 2011, treated with cefixime as recommended by Public Health Agency of Canada guidelines. MAIN OUTCOME MEASURES: Cefixime treatment failure, defined as the repeat isolation of N. gonorrhoeae at the test-of-cure visit identical to the pretreatment isolate by molecular typing and explicit denial of reexposure. RESULTS: There were 291 N. gonorrhoeae culture-positive individuals identified. Of 133 who returned for test of cure, 13 were culture positive; 9 patients were determined to have experienced cefixime treatment failure, involving urethral (n = 4), pharyngeal (n = 2), and rectal (n = 3) sites. The overall rate of clinical treatment failure among those who had a test of cure was 6.77% (95% CI, 3.14%-12.45%; 9/133). The rate of clinical failure associated with a cefixime MIC of 0.12 μg/mL or greater was 25.0% (95% CI, 10.69%-44.87%; 7/28) compared with 1.90% (95% CI, 0.23%-6.71%; 2/105) of infections with cefixime MICs less than 0.12 μg/mL, with a relative risk of 13.13 (95% CI, 2.88-59.72; P < .001). CONCLUSION AND RELEVANCE: The rate of clinical failure following treatment of N. gonorrhoeae infections with cefixime was relatively high at a Toronto clinic and was associated with elevated MICs.

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
