Abstract
Deep-vein thrombosis (DVT) and pulmonary embolism are among the most common complications of heparin-induced thrombocytopenia (HIT), an antibody-mediated adverse effect of heparin that leads paradoxically to in vivo activation of platelets and the coagulation system. Inappropriate treatment of HIT-associated DVT with warfarin can cause the DVT to progress to limb gangrene: this results from impaired ability of the protein C natural anticoagulant pathway to down-regulate thrombin generation, thus leading to microvascular thrombosis and tissue necrosis. Appreciation of the importance of coagulation system activation in HIT provides a rationale for treatments that reduce thrombin generation, either via inhibiting factor Xa (danaparoid) or via inhibiting thrombin directly (lepirudin). Clinicians should know how to distinguish HIT from other thrombocytopenic disorders: for example, thrombocytopenia associated with pulmonary embolism can mimic HIT (pseudo-HIT), and acute dyspnea that can mimic acute pulmonary embolism can result from acute in vivo platelet activation in a patient with HIT antibodies who receives heparin bolus therapy (pseudo-pulmonary embolism).

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; both teacher heads agree on what is shown here.
