Abstract
OBJECTIVE: To evaluate the utility of cosyntropin 1 microg in assessing adrenal function in critically ill patients. DATA SOURCES: A computerized literature search using MEDLINE, EMBASE, International Pharmaceutical Abstracts, and the Cochrane Database (1966-August 2004) was undertaken for trials evaluating cosyntropin 1 mug using the following search terms: adrenocorticotropin-releasing hormone (ACTH), cosyntropin, adrenal insufficiency, cortisol, corticosteroids, glucocorticoids, sepsis, septic shock, diagnosis, critically ill, intensive care, and critical care. STUDY SELECTION AND DATA SYNTHESIS: Identifying patients with sepsis with relative adrenal insufficiency (AI) using cosyntropin testing may identify those likely to benefit from corticosteroids. The results of 5 heterogeneous studies in non-intensive care unit (ICU) patients suggest that both 1 microg and 250 microg of cosyntropin stimulate similar cortisol responses and that testing using both doses correlates well with results from insulin tolerance testing. Some data from non-ICU patients suggest that the 1-microg test may be more sensitive to detect AI; 3 heterogeneous studies in ICU patients confirmed the improved sensitivity of the 1-microg test. CONCLUSIONS: Use of cosyntropin 1 microg should detect AI in all patients who would have been diagnosed using 250 microg. Unfortunately, all of the clinical trials evaluating the role of corticosteroids in septic shock that used the cosyntropin stimulation test administered 250 microg. Extrapolation of the existing guidelines to treat patients with septic shock testing positive for relative AI using the 1-microg test may provide effective therapy to appropriate patients not diagnosed by the 250-microg testing or may introduce additional adverse effects in patients who should not receive corticosteroids. Large-scale, head-to-head comparison data of steroid effectiveness after 1- and 250-microg ACTH stimulation tests are needed to expand upon these promising results.

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 it
