Abstract

fetched live from OpenAlex

Infectious agents have been implicated in the pathogenesis of pediatric acute lymphoblastic leukemia (ALL). A novel human DNA virus, TT virus (TTV), has been identified in children possessing characteristics as an etiologic agent, making the virus a potential candidate. Analysis of specimens from children with ALL was performed to determine if an association exists. Archived specimens (79 peripheral blood mononuclear cells, PBMC/bone marrow cells, BMC, and 125 cerebrospinal fluid, CSF) obtained at diagnosis and during therapy from 28 pediatric patients were tested for TTV. All of the diagnostic BMC/PBMC were negative for TTV, but 7 patients had follow-up specimens that converted to TTV positivity. TTV was not detected in any CSF. The absence of TTV at diagnosis suggests TTV is unlikely to be causally associated with ALL in the cases analyzed. However, the data support TTV transmission through blood products and suggest that the CNS is not a sanctuary site for TTV.

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.
