Embolic Brain Abscess in a Patient With Tricuspid Valve Endocarditis and a Patent Foramen Ovale
Bibliographic record
Abstract
Brain abscess results from local or metastatic septic spread to the brain. Approximately, 15-60% of brain abscesses are considered to be cryptogenetic, being the primary infectious site often undetected. Patent foramen ovale (PFO) has been suggested as a potential source of paradoxical embolism; this was suggested after detecting a higher prevalence of PFO in ischemic stroke of unexplained cause. Brain abscess may develop as a consequence of paradoxical infectious emboli from an extracranial infective source. We present the case of a patient with no history of intravenous drug use and no periodontal disease, which was found to have a brain abscess, tricuspid valve endocarditis and the presence of a PFO with right to left shunting with no other source of infection. doi:10.4021/jnr116w

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.
