Abstract

fetched live from OpenAlex

We report on a case of Salmonella enterica meningitis in a healthy, immunocompetent adult who presented with a thunderclap headache. This case illustrates the importance of avoiding early diagnostic closure, particularly when initial results are unrevealing. Although Salmonella enterica meningitis is exceedingly rare, this patient's persistent symptoms of nausea,vomiting and ongoing, without a history of migraine prompted further evaluation despite a negative non-contrast head CT for subarachnoid hemorrhage. A subsequent lumbar puncture ultimately confirmed the diagnosis. This case highlights the need for emergency physicians to maintain a broad differential diagnosis and continue diagnostic workups when clinical suspicion remains high, even in the absence of classic signs of life- threatening conditions like meningitis.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
