Blood pressure abnormalities in children with chronic kidney disease
Bibliographic record
Abstract
OBJECTIVES: Disturbances of blood pressure (BP) rhythms have been demonstrated in patients with various degrees of renal impairment. The purpose of this study was to determine the prevalence of BP abnormalities in children with chronic kidney disease (CKD) and evaluate possible factors associated with nocturnal BP abnormalities. METHODS: 42 children between 2 and 19 years of age with CKD stages 2-5 completed 24-h ambulatory BP monitoring. RESULTS: The percentage of patients with daytime hypertension was less than 10% but rates were higher at nighttime where 14% had systolic and 24% diastolic hypertension. A similar percentage of patients had a BP load >50%. BP abnormalities that were not evident in clinic BP readings were identified in 49% of the participants. The nocturnal BP dipping percentage tended to decrease as the estimated glomerular filtration rate decreased. Proteinuria was significantly associated with nocturnal BP nondipping. CONCLUSION: 24-h ambulatory BP monitoring may provide additional insight into hypertension in pediatric patients as early as CKD stage 2. Several BP abnormalities were identified that were not evident in casual BP measurements including nocturnal hypertension, elevated BP load, and nocturnal BP nondipping.

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.
