Pre-school traumatic brain injury and its impact on social development at 8 years of age
Bibliographic record
Abstract
OBJECTIVE: To confirm the clinical impression that younger pre-school children (<4 years at time of injury) who are referred to a tertiary care centre for management with moderate-to-severe traumatic brain injury (TBI) have poorer social, cognitive, physical and emotional outcomes compared to older pre-schoolers (4-6 years at time of injury) and to describe the prevalence and severity of their social impairment at 8 years of age. METHODS: This is a retrospective review of pre-schoolers with moderate-to-severe TBI from 1995-2009. Their social, cognitive, physical and emotional outcomes were assessed at 8 years of age using the Mayo-Portland Adaptability Inventory-Paediatric. RESULTS: Of 130 pre-schoolers enrolled in the database who sustained a TBI < 6 years, 93 were seen at 8 years of age (57 males, 36 females). Younger pre-schoolers (n = 61, mean 2.6 years) had inferior social outcomes (p = 0.04) and cognitive abilities (p = 0.006), trended toward poorer physical outcomes (p = 0.1), with no difference for emotional outcomes (p = 0.2), compared to older pre-schoolers (n = 32, mean 5.0 years). Overall, 19/93 had normal social function, 38/93 had mild impairment, 21/93 had moderate impairment and 15/93 had severe impairment to social function. CONCLUSIONS: Children <4 years at the time of moderate-to-severe TBI have poorer social, cognitive and physical outcomes compared to older pre-schoolers.

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.
