Abstract
Background: Acute circulatory failure after successfull resuscitation of cardiac arrest remains challenging and multifactorial. As the main driver of early mortality after restoration of spontaneous circulation, its therapeutic management essentially relies on fluids administration and vasopressive support using noradrenaline. Data also support the potential impact of a hormonal defect in this setting. Steroids substitution as well as argini-vasopressin treatment should be evaluated in these patients. Methods: The HYVAPRESS trial is a 2x2 factorial randomized placebo-controlled multicentric trial evaluating the effect of both hydrocortisone and arginin-vasopressin in successfully resuscitated (inhospital and out-of-hospital) cardiac arrest patients suffering an acute circulatory failure in the first 24 h after restoration of spontaneous circulation. The main outcome will be the favourable neurological outcome assessed by the Glasgow Outcome Scale (GOS). 380 patients will be included, i.e. 95 patients in each arm, allowing the detection of a 15% difference in mortality using a power of 80% and an alpha-risk of 5%. Discussion: Assessing therapeutics in the hemodynamic failure in post -cardiac arrest patients is challenging as the mortality is very high. Besides the vasopressive support, few investigation have been led so far to improve the management of these patients. While hydrocortisone and arginin-vasopressive have been evaluated in septic shock patients, data are lacking in this very specific subgroup of patients suffering from a very high mortality.

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 it
