Objective: To investigate the blood pressure responses to cold pressor stress and its relation to sodium metabolism in salt-sensitive children.
Method: 268 children aged 10.6 +/- 1.1 years were detected salt-sensitivity with the tests of oral saline load and furosemde sodium-volume depletion. Cold pressor stress test, sodium metabolism, and the related factors were measured.
Results: 25% of the children were detected to be salt-sensitive. The increased extent of blood pressure and its recovery time from peak to baseline in salt-sensitive children were significantly higher than those in non-salt-sensitive children during the cold pressor stress test (t = 5.14, 3.94, P < 0.01 and t = 2.16, P < 0.05). The increased extent of blood pressure and its recovery time during cold pressor test were correlated positively with red-cell sodium content, and were correlated negatively with 2 hour urinary sodium excreation during the oral saline load test.
Conclusion: Children with salt-sensitivity have a remarkably increased blood pressure responses to cold pressor stress (sympathetic activity), which is related with abnormal sodium metabolism.

Purpose: Dysfunction of vasomotor reactions due to arteriolar smooth muscle causes serious adverse events, such as loss of hemodynamic coherence. This in turn can increase risks of cardiovascular-related diseases. A noninvasive and quantitative evaluation of microvascular disorder is therefore very important for early diagnosis and treatment.

Music- and distraction-induced pain reduction have been investigated extensively, yet the main mechanism underlying music-induced analgesia remains unknown. In this study, to assess whether music-induced analgesia primarily operates through cognitive modulation, we used the cold pressor task and objectively compared the pain tolerances of participants in a four-group between-subjects design: a music group that listened to a music piece in the absence of any tasks, a music-and-attention-to-music group that listened to the same piece while also rating the arousal levels in the music, a music-and-attention-to-pain group that rated their pain levels while listening to the same piece, and a silence group as control. The group passively exposed to music playback did not show significantly higher pain tolerance compared to the silence group.

Nociceptors contribute to the cardiovascular responses during a cold pressor test (CPT). While these responses are lower in females, data suggest that they perceive the CPT as more painful. Thus, we examined sex differences in associations between pain and cardiovascular responses to a CPT (Aim 1) as well as differences between females using (OC), and not using (NC), an oral contraceptive (Aim 2).

Background: Previous studies demonstrated that task-specific stress appraisals as well as the more general belief that stress is (mal)adaptive (i.e., stress mindset) can affect the stress response.

Background And Objectives: Laboratory-based stress inductions are commonly used to elicit acute stress but vary widely in their procedures and effectiveness. We compared the effects of stress induction techniques on measures of two major biological stress systems: the early sympathetic-adrenal-medullary (SAM) and the delayed hypothalamic-pituitary-adrenal (HPA) axis response.
Design: A review and meta-analysis to examine the relationship between stress induction techniques on cardiorespiratory and salivary measures of SAM and HPA system activity.
