Transfusion-associated graft versus host disease
Bibliographic record
Abstract
OBJECTIVES: To review the epidemiology, pathophysiology, therapeutic and preventive strategies of transfusion associated graft versus host disease (TA-GVHD) and relate the findings to the critically ill child. DESIGN: Review article of published medical literature related to TA-GVHD. DATA SOURCES: Medline, bibliography search, published national and institutional guidelines. STUDY SELECTION: Original publications including prospective studies, case reports, case series, laboratory studies, and animal work. DATA EXTRACTION: Data were extracted manually after we reviewed selected articles and assessed their contribution to knowledge of TA-GVHD. DATA SYNTHESIS: New and significant historic information from the selected publications relating to incidence, therapy, prevention, and complications of preventive therapy of TA-GVHD was incorporated. CONCLUSIONS: Pediatric critical care practitioners should be aware of this preventable but fatal complication of cellular blood product transfusion. High-risk categories include congenital and acquired immunodeficiency, younger age, transfusion of blood donated by family members, and transfusion with fresh whole blood. Children at risk for the development of TA-GVHD include neonates, infants, and children with congenital heart disease, not restricted to children with "classic" DiGeorge syndrome. At present, risk identification and targeted prevention are the only methods to manage TA-GVHD. Aside from minimizing cellular blood product exposure, blood product irradiation is the only established and widely available method to prevent TA-GVHD. Transfusion guidelines need to reflect a balance between the incidence of TA-GVHD and the costs of instituting irradiation to selected groups or as routine transfusion policy.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
