Abstract

fetched live from OpenAlex

We studied the associations of a biphasic waveform identified in 61 consecutive patients by activated partial thromboplastin times performed with an MDA 180 coagulation analyzer (bioMérieux Inc., Durham, NC, USA). The patients were encountered in a wide range of locations, including medical and surgical services, emergency and outpatient departments, and intensive care unit. The patients encountered also had a variety of clinical diagnoses. Of the patients, 42.6% were dead on follow-up evaluation at 3 months, and 67.2% had a clinical condition known to predispose to the development of disseminated intravascular coagulation (DIC). Sepsis was the most frequent associated condition and was present in 54% of the patients. Only 6 patients had overt DIC according to a standardized scoring system. However, D-dimer was elevated in 90% of patients, and antithrombin III and protein C levels decreased in 75.4% and 63.9%, respectively. The platelet count was decreased in 26%. Our results indicated that a biphasic waveform is associated with high mortality in general hospital patients and is frequently associated with sepsis. This waveform appears to be associated with a consumptive procoagulant state, which may represent early or nonovert DIC.

Teacher imitation

Not 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.
