Abstract

fetched live from OpenAlex

BACKGROUND: A complex network of biological mediators underlies the clinical syndrome of sepsis. The nonspecific physiologic criteria of sepsis syndrome or the systemic inflammatory response syndrome do not adequately identify patients who might benefit from either conventional anti-infective therapies or from novel therapies that target specific mediators of sepsis. Validated biomarkers of sepsis may improve diagnosis and therapeutic decision making for these high-risk patients. OBJECTIVES: To develop a methodologic framework for the identification and validation of biomarkers of sepsis. METHODS: A small group meeting of experts in clinical epidemiology, biomarker development, and sepsis clinical trials; selective narrative review of the biomarker literature. RESULTS: The utility of a biomarker is a function of the degree to which it adds value to the available clinical information in the domains of screening, diagnosis, risk stratification, and monitoring of the response to therapy. We identified needs for greater standardization of biomarker methodologies, greater methodologic rigor in biomarker studies, wider integration of biomarkers into clinical studies (in particular, early phase studies), and increased collaboration among investigators, pharmaceutical industry, biomarker industry, and regulatory agencies. CONCLUSIONS: Biomarkers promise to transform sepsis from a physiologic syndrome to a group of distinct biochemical disorders. This transformation could aid therapeutic decision making, and hence improve the prognosis for patients with sepsis, but will require an unprecedented degree of systematic investigation and collaboration.

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.
