Elevated Intact Parathyroid Hormone Is Associated with Reduced Biochemical Markers of Bone Formation and Resorption Measured in Blood in Infant Piglets Receiving Oral Dexamethasone for 15 Days
Bibliographic record
Abstract
Seven-day-old male Yorkshire piglets were randomized to receive either dexamethasone (DEX) 0.5 mg/kg/day or placebo (water) for 15 days (n = 8/group). Body weight and length, plasma intact parathyroid hormone (PTH), N-Mid osteocalcin and C-terminal telopeptide of type I collagen (CTx) were measured at baseline and end of the study. The indices of bone metabolism did not differ between DEX and placebo groups at baseline. At the end of the study, plasma intact PTH was increased (p < 0.01) and N-Mid osteocalcin (p < 0.01) and CTx (p < 0.01) were decreased from baseline value in the DEX group but not in the placebo group. The reduction (Z-score) in N-Mid osteocalcin was greater than that in CTx (p < 0.05). We conclude that exogenous DEX in young piglets stimulates a rise in circulating intact PTH. Both circulating CTx and osteocalcin are reduced with the decline in osteocalcin greater than that in CTx.

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.
