Ultradian Oscillations of Plasma Glucose, Insulin, and C Peptide in Man During Continuous Enteral Nutrition

SIMON, C., BRANDENBERGER, G., FOLLENIUS, M.·1987·The Journal of Clinical Endocrinology & Metabolism

Abstract

The profiles of plasma glucose, insulin, and C-peptide were studied in normal men receiving continuous enteral nutrition. Large oscillations occurred with periods of 53-113 min. Their mean amplitudes, expressed as a percentage of the 24-h mean, were as high as 20% for glucose, 54% for insulin, and 56% for C-peptide. The oscillations of plasma insulin levels throughout the 24 h were concomitant with those of C-peptide. Rapid 8- to 14-min plasma insulin and glucose oscillations were smaller in magnitude and could only be detected in some segments of the longer period oscillations. These results indicate that in addition to the previously described 8- to 14-min oscillations, plasma glucose, insulin, and C-peptide oscillate at a mean 80-min periodicity in man during continuous enteral nutrition. These oscillations may reflect a pancreatic oscillatory mechanism and/or cyclic variations in gastrointestinal motility or peripheral glucose uptake.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • Growth hormone levels increase during sleep regardless of when sleep occurs and are markedly reduced during sleep deprivation.

    “GH levels are increased during sleep, irrespective of the time at which sleep occurs, and they are markedly diminished during sleep deprivation.”

    From Sleep and metabolic function (2012) · cites this paper as [151]

  • The 24-hour cortisol profile is only modestly affected by the presence or absence of sleep.

    “As shown in Fig. 1b, this profile is only modestly affected by the presence or absence of sleep.”

    From Sleep and metabolic function (2012) · cites this paper as [151]

  • Under constant glucose infusion, the major cause of decreased glucose tolerance during sleep is decreased glucose utilization.

    “Under these experimental conditions, the major underlying cause of the decrease in glucose tolerance is decreased glucose utilization.”

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.
