Plasma Beta-Endorphin Concentrations in Neonates Associated with Acute Stress
Bibliographic record
Abstract
Plasma beta-endorphin concentrations were measured in two groups of neonates. The control group (group 1) consisted of 20 infants with a mean gestational age of 31.5 +/- 0.6 weeks and a mean birth weight of 1,720 +/- 135 g. Blood samples were collected at a mean postnatal age of 1.0 +/- 0.3 days. Group 2 consisted of 23 infants with clinical evidence of acute illness and associated significant stress who had a mean gestational age of 33.2 +/- 1.1 weeks and a mean birth weight of 2,075 +/- 225 g. Their blood samples were collected at a mean postnatal age of 3.4 +/- 1.3 days. The mean beta-endorphin concentration in group 1 was 27.8 +/- 6 pg/ml and 63.9 +/- 4.2 pg/ml in group 2 (p less than 0.05). No correlation was observed for gestation or birth weight and beta-endorphin concentrations in group 1; however, in group 2 a positive correlation was seen for gestational age and plasma beta-endorphin concentrations (r = 0.4411) suggesting an increased release of plasma beta-endorphin with increasing gestation when faced with significant clinical stress.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
