A Prospective Outcome Study of Neonatal Cerebral Sinovenous Thrombosis
Bibliographic record
Abstract
Neonatal cerebral sinovenous thrombosis is a frequent contributor to neonatal mortality and morbidity. Treatment is controversial, and reported clinical outcomes vary widely. Newborns with radiologically confirmed neonatal cerebral sinovenous thrombosis from 1992 to 2009 were prospectively followed in our Children's Stroke Clinic for standardized outcomes, including the Pediatric Stroke Outcome Measure. Outcomes were available in 90 of 104 (87%) neonates. Early outcomes included cerebral sinovenous thrombosis-associated death (5) and thrombus propagation (15 [6 associated with new venous infarcts]). Lack of anticoagulation predicted propagation (RR = 13; P = .0007). Complete thrombus recanalization occurred in 90% by 3 months. Late outcomes (median, 2.5 years) were epilepsy (15) and neurological disability (50), which included moderate-severe language (43), sensorimotor (38), and cognitive/behavioral (24) deficits. Overall, 61% had poor outcome (death/any deficit). Concurrent neurological comorbidity at diagnosis (odds ratio = 2.8; P = .029) predicted poor outcome. Clinical trials are urgently needed to establish more effective treatment strategies.

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.
