Cardiovascular autonomic dysfunction and sleep abnormalities in children with Prader-Willi syndrome.

Article Synopsis
- Prader-Willi syndrome (PWS) is a rare genetic condition linked to cognitive and behavioral issues, obesity, and sleep problems, which may also involve autonomic nervous system dysfunction.
- A study investigated heart rate variability and autonomic function during sleep and standing in children with PWS, comparing results with age-matched controls, revealing significant impairment in heart rate responses and high rates of sleep apnea among the PWS group.
- Findings suggest decreased vagal modulation and possible sympathetic dysfunction in PWS children, which could increase their cardiovascular risks.
Competitive (but not cooperative) body odors bias the discrimination of action intentions towards cooperation.

Odors help us to interpret the environment, including the nature of social interactions. But, whether and how they influence the ability to discriminate the intentional states embedded in actions is unclear. In two experiments, we asked two independent groups of participants to discriminate motor intentions from videos showing one agent performing a reach-to-grasp movement with another agent with a cooperative or a competitive intent, and the same movement performed alone at either natural- or fast-speed, as controls.

Cognitive Arousal, frequently elicited by environmental stressors that exceed personal coping resources, manifests in measurable physiological markers, notably in galvanic skin responses. This effect is prominent in cognitive tasks such as composition, where fluctuations in these biomarkers correlate with individual expressiveness. It is crucial to understand the nexus between cognitive arousal and expressiveness.

Purpose: This exploratory study aimed to examine the psychophysiological responses to HIIT over the menstrual cycle.
Methods: Twenty-three healthy and physically active young women were recruited.

Study Objectives: to characterize possible differences in the function of the ANS in patients with chronic insomnia compared to a control group, using a wearable device, in order to determine whether those findings allow diagnosing this medical entity.
Methods: Thirty-two patients with chronic insomnia and nineteen patients without any sleep disorder, as a control group, were recruited prospectively. Both groups of patients underwent an in-patient night with simultaneous polysomnography and wearable device recording Empatica E4 a diverse array of physiological signals, including electrodermal activity, temperature, accelerometry, and photoplethysmography, providing a comprehensive resource for in-depth sleep analysis.
