Abstract

fetched live from OpenAlex

Methadone is a synthetic opioid used to treat pain and opioid dependence. Despite its benefits, accidental ingestion of methadone in pediatric patients can lead to significant morbidity and mortality. Documented findings of acute toxicity secondary to methadone ingestion in children include leukoencephalopathy and cerebellitis. There is limited research into treatment and factors influencing clinical outcomes following methadone overdose in children. We report a 3-year-old child with severe brain injury and death following accidental ingestion of methadone. Our case is unique in that we were able to acquire a serum methadone level following ingestion, which was used to guide intervention and treatments. Using this case, we aim to contribute to the growing understanding of methadone toxicity while also advocating for the implementation of policies that protect our pediatric population.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
