Abstract
OBJECTIVE: To determine the association between hemodynamic instability requiring inotropes and brain injury or death in neonates with hypoxic ischemic encephalopathy (HIE). METHODS: Retrospective cohort study of 221 neonates with HIE. Brain injury was defined using four HIE patterns based on MRI diffusion or T1 changes. The primary outcome was death or brain injury. Secondary outcomes were abnormal MRI, death, and abnormal EEG. Logistic regression was used to examine the risk of death or brain injury with the use of inotropes while adjusting for confounding factors. RESULTS: Brain injury or death occurred more often in neonates who received inotropes (71.1%, 69/97) compared to those who did not (44.3%, 55/124). The use of inotropes was associated with increased risk of death or brain injury (OR 3.11; 95% CI 1.39-7.004) and abnormal MRI (OR 2.78; 95% CI 1.22-6.34) after adjusting for confounding factors. Mortality was significantly higher in neonates exposed to inotropes (21.6%, 21/97) compared with those who did not receive inotropes (4%, 5/124), P < 0.001. CONCLUSION: In infants with HIE, hemodynamic instability requiring inotropes in the first 72 hours of life was associated with increased risk of death or brain injury detected by MRI.

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
