A Rare Case of <i>Corynebacterium propinquum</i> Endocarditis in a Native Valve
Bibliographic record
Abstract
We report a case of a 63-year-old male who presented with complaints of 9 days of fevers up to 38.3 °C, chills and rigors, and headache of 3 - 4 days duration. He also noticed that the entire right half of his visual field was obscured. MRI of the brain revealed a 4 cm acute infarction involving the calcarine cortex of the left occipital lobe. Blood cultures grew Corynebacterium propinquum. A trans-esophageal echocardiogram revealed oscillating echodensities on the aortic valve, mitral valve, and posterior leaflet of the tricuspid valve, concerning for infective endocarditis. Repeat bubble study was consistent with a small patent foramen ovale. To the best of our knowledge, there have only been four reported cases of infection by this organism, with just two of them being infective endocarditis. There are no established guidelines for therapy. We used an Etest with minimum inhibitory concentrations (MICs) reported to guide therapy. The patient was successfully treated with 6 weeks of intravenous ceftriaxone. J Med Cases. 2017;8(4):137-140 doi: https://doi.org/10.14740/jmc2795w

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.
