Abstract

Potassium is the most abundant cation in the intracellular fluid, and maintaining the proper distribution of potassium across the cell membrane is critical for normal cell function. Long-term maintenance of potassium homeostasis is achieved by alterations in renal excretion of potassium in response to variations in intake. Understanding the mechanism and regulatory influences governing the internal distribution and renal clearance of potassium under normal circumstances can provide a framework for approaching disorders of potassium commonly encountered in clinical practice. This paper reviews key aspects of the normal regulation of potassium metabolism and is designed to serve as a readily accessible review for the well informed clinician as well as a resource for teaching trainees and medical students.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • An increase in aldosterone concentration leads to a modest increase in Na+-K+-ATPase abundance, which increases K+ flux into cells.

    “An increase in ALD concentration leads to a modest increase in Na+-K+-ATPase abundance, which increases K+ flux into cells [30–32].”

    From A mathematical model of potassium homeostasis: Effect of feedforward and feedback controls (2022) · cites this paper as [31]

    The Introduction states that aldosterone stimulates basolateral Na+-K+-ATPase activity in renal principal cells, increasing intracellular K+ concentration. It does not say that aldosterone modestly increases the pump’s abundance; the passage supports increased activity, not the claimed change in abundance. (LLM, conf=0.86)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
