Abstract

fetched live from OpenAlex

Transfusion-associated septic events have been reduced by the introduction of improved donor screening and skin disinfection methods, as well as implementation of first aliquot diversion and bacterial testing. The frequency of bacterial contamination in platelet concentrates varies broadly within countries. Platelet concentrates (PCs) are the blood components most susceptible to bacterial contamination due to their storage conditions being amenable for bacterial growth. Contaminant bacteria of blood components can originate from the donor or the blood collection and processing procedures. Strategies used to decrease the levels of bacterial contamination in blood components include donor screening, skin disinfection, first aliquot diversion, pretransfusion detection and pathogen reduction technologies. Routine testing of PCs for bacterial contamination has been implemented worldwide. Detection of bacteria in transfusable blood components is more complex than viral detection, since bacterial load increases over time under routine blood component storage conditions.

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.
