Renal Potassium Handling during States of Low Aldosterone Bio-Activity: A Method to Differentiate Renal and Non-Renal Causes
Bibliographic record
Abstract
The purpose of this study was to examine renal potassium handling in patients with low aldosterone bio-activity. The patients with a normal renal response to aldosterone were identified by finding both a low plasma aldosterone concentration during hyperkalaemia and a transtubular potassium concentration gradient (TTKG) in the cortical distal nephron of 6 or greater within 4 h after the administration of a physiologic dose of mineralocorticoid hormone. In contrast, patients with a primary renal potassium excretion defect represent a heterogeneous population. In some, the TTKG rose when a pharmacologic but not a physiologic dose of mineralocorticoid was given; others had little renal response to the administration of this hormone. Furthermore, this renal response may be delayed and require more than 24 h to become manifest.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
