Plasma Amino Acid Profile on Nocturnal Hemodialysis
Bibliographic record
Abstract
BACKGROUND/AIMS: The purpose of this study was to examine the effect of nocturnal hemodialysis (NHD) on serum amino acid (AA) profile. METHODS: In a cross-over trial, we studied the AA profile in 11 patients who were switched from conventional hemodialysis to NHD. Plasma levels of AA were measured at monthly intervals for a period of 1 year. RESULTS: Concentrations of AA isoleucine, threonine, phenylalanine, valine, glycine, glutamine and taurine increased on switch to NHD. Total AA (2,907.2 +/- 542.2 vs. 3,870.2 +/- 715.2 micromol/l, p = 0.03), essential AA (EAA, 842.2 +/- 259.4 vs. 1,125. 8 +/- 235.3 micromol/l, p = 0.03), nonessential AA (NEAA, 2,307.2 +/- 399.1 vs. 2,879.5 +/- 581.2 micromol/l, p = 0.03), and branched chain AA (315.5 +/- 90.8 vs. 386.0 +/- 114.3 micromol/l, p = 0.05) concentrations were significantly higher on NHD. However, abnormalities in the ratios of EAA/NEAA, valine/glycine and tyrosine/phenylalanine persisted during NHD. CONCLUSIONS: NHD alleviated some abnormalities in the aminogram of uremia, but other metabolic derangements lingered.

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.
