Abstract

fetched live from OpenAlex

A 26-year-old woman, diagnosed with diffuse large B-cell lymphoma, was treated with CHOP (cyclophosphamide, hydroxydaunomycin, oncovin, prednisone), rituximab and radiotherapy. She developed transfusion-dependant anaemia, which persisted following chemotherapy. Bone marrow aspirate and biopsy were consistent with pure red cell aplasia and parvovirus infection. Serology was negative for previous or acute infection but parvovirus DNA was detected by polymerase chain reaction. Administration of intravenous immunoglobulin (1 g/kg) resulted in reticulocytosis and recovery of her haemoglobin. We hypothesize that rituximab caused depletion of her normal B cells, resulting in an inability to mount a primary immune response to parvovirus infection.

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.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
