Abstract

fetched live from OpenAlex

A 30-year-old male was referred to Hematologic Oncology after 6 months of worsening lymphadenopathy and symptoms of fatigue, night sweats, weight loss, and shortness of breath. At the time of referral, the patient reported that he had deteriorated to the point that he was unable to work or perform his previous level of physical activity. On examination, the patient was not in acute distress, with normal vital signs. Bilateral cervical, axillary, and inguinal adenopathy were present on clinical examination. The abdomen was soft and nontender with no obvious hepatosplenomegaly. The patient identified as a regular smoker with occasional use of alcohol and marijuana. There was no history of injection drug use or recent travel outside the country. With respect to family history, his maternal grandmother was diagnosed with non-Hodgkin’s lymphoma, and two cousins were diagnosed with liver and colon cancer. Initial laboratory investigations are summarized in Table 1. Tests revealed profound anemia, thrombocytosis, and marked hypergammaglobulinemia. Serum and urine protein electrophoresis did not reveal monoclonal gammopathy but the patient had nephrotic range proteinuria with normal serum creatinine. Further bloodwork revealed active inflammation with an elevated erythrocyte sedimentation rate, increased C-reactive protein and ferritin concentrations, as well as decreased complement C4. Infectious causes of lymphadenopathy and systemic inflammation were excluded as the patient tested negative for hepatitis B, hepatitis C, Epstein-Barr virus, human immunodeficiency virus, and human herpesvirus 8 (HHV8). HHV8 status was confirmed via nodal tissue staining, immunofluorescence assay, and peripheral blood PCR. However, an underlying autoimmune disorder was considered in view of an increased rheumatoid factor despite the patient denying any active joint symptoms. Due to concerns with rapid clinical deterioration—particularly with regards to renal function—the patient was started on prednisone (1 mg/kg) while additional investigations were pursued to determine the cause of the lymphadenopathy.

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.
