A Prospective Observational Study of Changes in Renal Function and Cardiovascular Risk Following Living Kidney Donation
Bibliographic record
Abstract
The effect of unilateral nephrectomy on the cardiovascular risk profile of living kidney donors has not been prospectively studied. We performed an observational cohort study of 58 living donors to 6 months postdonation for changes in 24-hr ambulatory blood pressure profiles, renal function, urine protein excretion, body mass index, glucose tolerance, and fasting lipid profiles. The 24-hr systolic blood pressure average and night-day ratio were unchanged from pre- to postdonation (118.9+/-11 vs. 118.1+/-14 mm Hg, P=0.77; 0.87+/-0.07 vs. 0.87+/-0.09, P=0.68, respectively). Estimated glomerular filtration rate declined from 91.9+/-16 to 61.6+/-12 mL/min/1.73 m2 (P<0.0001). Protein excretion, body mass index, glucose, and lipids were unchanged. No significant differences were noted between dippers and nondippers either pre- or postdonation. In summary, living kidney donation in the short term is safe. We suggest further observation of individuals with lower glomerular filtration rate for possible increased cardiovascular risk factors in the future.

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.
