Coagulation factor XIII-A and activated FXIII-A decrease in some deep vein thrombosis patients following catheter-directed thrombolysis
Bibliographic record
Abstract
: The objective of the study was to assess the effect of tissue plasminogen activator administered during catheter-directed thrombolysis (CDT) on coagulation factor XIII (FXIII). Thrombolytic therapy carries significant risks, such as life-threatening bleeds. The mechanisms responsible for major bleeds and intracerebral hemorrhages during thrombolysis are not fully understood. Activated FXIII (FXIII-A) lies at the intersection of coagulation and fibrinolysis. Using purified proteins and blood collected from nine deep vein thrombosis patients undergoing CDT, the stability of FXIII-A and FXIII were measured immediately before, immediately after and 1-day post thrombolysis. We found that purified tissue plasminogen activator directly degraded FXIII-A. During CDT, FXIII levels were decreased by more than 40% in five of nine patients and FXIII-A levels were decreased by more than 85% in two patients when it was activated. FXIII-A and FXIII-A can decrease during CDT in some patients, warranting further research into the role of FXIII-A in bleeding from thrombolysis.

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.
