Abstract
STUDY DESIGN: Retrospective case series. OBJECTIVE: To determine relevant demographics, clinical presentations, and outcomes of this condition. SUMMARY OF BACKGROUND DATA: This is the first study looking specifically at methicillin-resistant Staphylococcus Aureus (MRSA) spondylodiscitis. METHODS: We performed a retrospective review of patients presenting between 2000 and 2005. RESULTS: Thirteen cases were identified. The mean age was 65 years; 85% were male. All cases presented with back pain, spinal tenderness, and systemic upset. Neurologic deficit was present initially in 39%, and 8% developed neurologic deterioration during treatment. The thoracic spine (53%) was most commonly affected, followed by the lumbar (33%), thoracolumbar junction (7%), and cervical spine (7%); 16% of cases were multilevel. The white cell count, erythrocyte sedimentation rate and C-reactive protein were elevated in all cases with means of 17.3 x 10(-9)/L, 102 mm/h, and 236 mg/L, respectively. Radiologic diagnosis was established with MRI in all cases. The most common risk factors were diabetes mellitus (62%), malnourishment (54%), cirrhosis (31%), end-stage renal failure (15%), and intravenous drug use (15%). Multiple risk factors were present in 76% of cases, and only 15% had no identifiable risk factors. The main sources of sepsis were intravenous catheters (23%), urinary tract (15%), and intravenous drug use (15%). Treatment consisted of intravenous vancomycin monotherapy for a mean period of 4 weeks followed by oral combination or monotherapy antimicrobials for a mean period of 8 weeks. Operative intervention was required in 38% of cases. At 6 months, 54% of cases were clinically free of infection, 38% had died, and 8% required ongoing treatment. Neurologic deficit was present in 50% of survivors. At 1 year, 29% of survivors had MRSA bacteremia and spondylodiscitis recurrence. CONCLUSION: This is a devastating condition with high mortality and morbidity.

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
