Clinical Presentation of Patients with Aseptic Meningitis, Factors Influencing Treatment and Hospitalization, and Consequences of Enterovirus Cerebrospinal Fluid Polymerase Chain Reaction Testing
Bibliographic record
Abstract
INTRODUCTION: Clinical and laboratory features of enteroviral meningitis may overlap with those of bacterial meningitis. In the present retrospective review, we compared features of enteroviral (EV)-positive and -negative patients to determine those that were most influential in admission, discharge and in anti-infective administration. METHODS: Data were analyzed from the records of 117 pediatric and adult patients who underwent cerebrospinal fluid (CSF) EV testing over a three-year period. RESULTS: The oldest EV-positive patient was 34 years of age and the occurrence of the disease was highly seasonal. EV-positive patients were more likely to report fever, rash, photophobia, short onset and exposure to an ill contact. A positive polymerase chain reaction (PCR) result was associated with relatively short hospitalization. Seizure and neurological symptoms were more strongly associated with a negative PCR test result. CSF characteristics did not discriminate well between patients with positive and negative PCR tests. Patients with imperfect Glasgow Coma Scores or with neurological symptoms were more likely to be admitted to hospital than those without. Fever and recent onset predicted determinants of anti-infective use. CONCLUSION: The present retrospective study confirms previous reports regarding seasonality and the young age of positive patients. Factors that indicate nonenteroviral etiology were appropriately also those that influenced hospitalization. Patients with EV meningitis were likely to be treated with empirical anti-infectives, and a substantial proportion continued to take antibiotics for more than 24 h after receiving the positive EV PCR test result.

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.
