Abstract

fetched live from OpenAlex

This chapter presents a case study of an 84-year-old woman, who is admitted to hospital with an intertrochanteric hip fracture and undergoes surgery for a cephalomedullary nail. Medical history is significant for coronary artery disease, hypertension, and chronic renal failure. Patient blood management is an evidence-based approach to reducing the need for transfusions, and, when necessary, making transfusions safer and more effective. Transfusion of blood products is both expensive and has numerous associated risks. Thus, it is important to identify evidence-based perioperative strategies that can reduce transfusion rates. Based on the emergence of high quality evidence, traditionally liberal transfusion thresholds have been re-evaluated and restrictive thresholds are advocated for most patients, particularly in the intensive care setting.

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.
