Abstract

fetched live from OpenAlex

A 33-year-old male presented to a chiropractic clinic complaining of chronic, recurrent low back pain. Subtle signs of muscle atrophy were noted in the left hand during the history taking. This muscle atrophy was reported as having a gradual onset spanning the past six months without any precipitating event. Cervical, thoracic and lumbar spinal radiographs were deemed unremarkable. Due to the progressive nature of the neurological deficit, the patient was referred for a neurological consultation. A magnetic resonance imaging (MRI) study was performed and revealed an expansive intramedullary lesion between C6 and T1 suggesting a differential diagnosis of spinal cord ependymoma or astrocytoma. The patient underwent surgical excision of the tumour. Pathological report confirmed a diagnosis of ependymoma. In the presence of subtle clinical signs, clinicians should keep a high index of suspicion for spinal cord tumours.

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.
