Abstract

fetched live from OpenAlex

Using the Doppler technique, the effect of therapeutic doses of indomethacin on the cerebral blood flow velocity (CBFV) of anterior cerebral arteries was studied in 13 preterm infants with patent ductus arteriosus. The first intravenous injection of indomethacin (0.2 mg/kg, group 1, n = 10) induced a significant decrease in the area under the velocity curve at 15 min (-22%), which was sustained until 120 min (-28%, p less than 0.005). In contrast, no significant change in CBFV occurred after the third dose (group 2, n = 7). In both groups, capillary blood gases, mean arterial blood pressure, and heart rate remained stable throughout the study. In 5 mechanically ventilated infants, the increase in CBFV secondary to suctioning was significantly attenuated after the first dose of indomethacin (p less than 0.02) but not after the third (p = 0.56). Thus, an initial dose of indomethacin may attenuate CBFV increases secondary to clinical manipulations in the preterm newborn.

Teacher imitation

Not 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.
