Abstract

fetched live from OpenAlex

BACKGROUND: Cerebral vasospasm after aneurysmal subarachnoid hemorrhage can lead to considerable mortality and morbidity affecting the intracranial vessels, leading to delayed cerebral ischemia and stroke. Therapeutic options for patients with treatment-refractory vasospasm are limited, particularly in the setting of significant cardiopulmonary disease. Administration of nicardipine, a calcium channel blocker, into the intrathecal space may represent a potential treatment option for this population. OBSERVATIONS: A 56-year-old woman had treatment-refractory vasospasm, severe acute respiratory distress syndrome, and Takotsubo cardiomyopathy. As an adjunct to vasopressor administration and endovascular intraarterial calcium channel blocker administration, the patient received intraventricular nicardipine. The patient demonstrated improved neurophysiology on invasive multimodality neuromonitoring, with increased cerebral blood flow and oxygenation as a result of intraventricular nicardipine administration. LESSONS: Intraventricular nicardipine can be used as rescue therapy for patients with treatment-refractory cerebral vasospasm. This case demonstrates that intrathecal nicardipine may prevent delayed ischemic neurological deficits and improve outcomes.

Teacher imitation

Not 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.
