Abstract

The influence of acute mental stress on cardiovascular responses and concentrations of inflammatory cytokines up to 2 h later was assessed in 12 subjects exposed to stress and in eight control subjects. Beat-by-beat recordings of finger blood pressure and heart rate were made at rest and during two behavioural tasks (colour-word interference and mirror tracing). Blood was drawn after adaptation and at 45 min and 2 h after the tasks, and assayed for interleukin-6 (IL-6), tumour necrosis factor-alpha (TNF-alpha), interleukin-1 receptor antagonist (IL-1Ra), C-reactive protein (CRP) and haematocrit. Saliva was sampled periodically and assayed for free cortisol. The tasks were rated as stressful by the participants. The stress group showed significant increases in systolic and diastolic blood pressure (mean rises of 16.4+/-12.3 and 12.6+/-6.9 mmHg respectively) and heart rate (5.39+/-5.3 beats/min); these values returned to baseline during the recovery period. The IL-6 concentration was increased by 56% at 2 h after the tasks (P<0.05), while IL-1Ra was increased by 12.3% (P<0.01). No changes in cardiovascular variables or cytokine concentrations were observed in the control subjects, and haematocrit did not change. The magnitude of blood pressure responses during tasks was correlated positively with the IL-6 concentration after 45 min (r=0.70, P<0.05), and with the IL-1Ra concentration after 2 h (r=0.63, P<0.05). Increases in TNF-alpha after 2 h were correlated with heart rate res…

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.
