Abstract

fetched live from OpenAlex

BACKGROUND: Levetiracetam (LEV) is an antiseizure medication (ASM) used as a second line after benzodiazepines for status epilepticus treatment. Current literature lacks direct head-to-head comparisons between different LEV loading dose strategies, leading to uncertainty about superior dosing methods and thus clinical practice variations. METHODS: A retrospective cohort study was designed to compare efficacy and safety of low (<30 mg/kg) versus high (≥30 mg/kg) weight-based LEV loading doses in adults with benzodiazepine-refractory status epilepticus (BRSE). The primary outcome of this study was termination of BRSE. No requirement for additional ASM after LEV was a surrogate for BRSE termination. Secondary endpoints included endotracheal intubation, intensive care unit (ICU) admission, 30-day all-cause mortality and adverse drug reactions. Statistical analysis included discrete and inferential statistics, including logistic regression and win-ratio analysis, to control for potential confounding variables. RESULTS: Of the 106 patients included in this study, 54 (51%) did not require additional ASM after LEV, thereby achieving seizure termination. There was a higher proportion of patients with seizure termination in the higher weight-based dosing group as compared to the lower weight-based group (66% vs 40%, respectively; aOR 3.07; 95% CI: 1.36-7.21). There were lower rates for endotracheal intubation, ICU admission and all-cause mortality in the higher dosing group. Adverse events were comparable between the both groups. CONCLUSION: LEV's high weight-based loading dose strategy (≥30 mg/kg) is more effective in the termination of BRSE as compared to the lower weight-based loading dose strategy (<30 mg/kg).

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.
