Abstract

fetched live from OpenAlex

Ochronosis and joint destruction are caused by accumulation of homogentisic acid in connective tissues1. Few cases have been reported of patients with severe ochronotic arthroplasty and need of surgical reconstruction with arthroplasty2,3,4. An 80-year-old white woman of Austrian descent presented at our outpatient clinic complaining of year-long pain and reduced range of motion in the right hip joint. Clinical and radiological examination showed severe osteoarthritis of the hip joint. Surgical reconstruction with primary total hip arthroplasty (THA) was indicated. Capsulotomy revealed dark brownish pigmentation of the cartilage of the hip joint. Histology of intracapsular tissue performed intraoperatively showed no signs…

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.
