Cytomegalovirus Ventriculoencephalitis in a Peripheral Blood Stem Cell Transplant Recipient
Bibliographic record
Abstract
Cytomegalovirus encephalitis occurs rarely in transplant recipients. We describe a patient with cytomegalovirus ventriculoencephalitis who had a very high CSF viral load but a low peripheral blood viral load. No resistance mutations were present in cerebrospinal fluid viral DNA, whereas DNA from blood showed a resistance mutation in the UL54 gene but not in the UL97 gene. Viral replication was intense in the brain ependyma and periventricular areas without evidence of peripheral cytomegalovirus disease. The data provide evidence for compartmentalization of cytomegalovirus infection. Levels of ganciclovir and foscarnet in the cerebrospinal fluid may be inadequate for treatment, even for some drug-susceptible strains, and, together with periventricular replication, may explain the disparity between cerebrospinal fluid viral load and peripheral blood viral load.
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 machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
