Case 2: Hyponatremia and hyperkalemia in a four-week-old boy
Bibliographic record
Abstract
A four-week-old male infant presented to the emergency department with failure to thrive (360 g below his birth weight), and had a history of poor eating, increased sleeping and irritability over his first month of life. The infant's family history was significant for polycystic kidney disease in his mother and female relatives. On presentation, his blood pressure was 102/74 mmHg, heart rate was 162 beats/min, respiratory rate was 52 breaths/min, oxygen saturation was 99% and rectal temperature was elevated at 39.4°C. A physical examination revealed a somewhat wasted, nondysmorphic, nontoxic baby with normal male genitalia. The rest of the physical examination was essentially normal. The infant's bloodwork showed a a sodium concentration of 121 mmol/L, and a potassium concentration of 7.1 mmol/L. (The tests were repeated and found to be accurate.) Capillary gases showed a pH of 7.32, bicarbonate of 13 mmol/L and PCO2 of 26 mmHg. An electrocardiogram was performed, which did not show any abnormalities. His urine test was positive for blood and leukocytes, but negative for nitrites.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
