Arterial Ischemic Stroke in an Adolescent With Presumed Perinatal Ischemic Stroke
Bibliographic record
Abstract
The risk of recurrent ischemic stroke after presumed perinatal stroke and the risk factors for such recurrence are rarely reported. Here, we present an adolescent with a history of presumed perinatal stroke who presented with arterial ischemic stroke recurrence at the age of 15 years. Hereditary thrombophilia screening performed at the time of his stroke recurrence demonstrated protein S deficiency. No evidence-based consensus guidelines on thrombophilia screening in children with presumed perinatal stroke exist, nor has the role of secondary prophylaxis been addressed. There is a risk of stroke recurrence after presumed perinatal stroke, and routine thrombophilia screening may identify those children who are at higher risk for recurrence and who might therefore benefit from secondary prophylaxis. Clear guidelines should be developed to standardize investigations and management of children with presumed perinatal ischemic stroke.

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.
