Abstract 111: Outpatients Referred for Carotid Doppler Evaluation Who Have Elevated Coated-Platelets Demonstrate Early Cognitive Impairment
Bibliographic record
Abstract
Background: Coated-platelets, a subset of procoagulant platelets observed upon dual agonist stimulation with collagen and thrombin, support a robust prothrombinase activity and provide a unique measure of platelet thrombotic potential. Our recently published data show that coated-platelet levels are increased in large artery stroke compared to controls, and higher levels are associated with early stroke recurrence. Because carotid occlusive disease and recurrent strokes are known risk factors for cognitive decline, we investigated the impact of coated-platelets on cognitive function among patients referred for carotid Doppler evaluation. Methods: Sixty consecutive patients without known dementia or stroke referred for carotid Doppler evaluation were screened for evidence of cognitive impairment using the Montreal Cognitive Assessment (MoCA). Coated-platelets were determined at baseline and are reported as percent of cells converted to coated-platelets. Differences in mean coated-platelet levels between gr...

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.
