Article Abstract

Large clinical trials designed to test the efficacy of vagus nerve stimulation (VNS) in patients with heart failure did not demonstrate benefits with respect to the primary endpoints. The nonselective nature of VNS may account for the failure to translate promising results of preclinical and earlier clinical studies. This study showed that optogenetic stimulation of vagal pre-ganglionic neurons transduced to express light-sensitive channels preserved left ventricular function and exercise capacity in a rat model of myocardial infarction-induced heart failure. These data suggested that stimulation of vagal efferent activity is critically important to deliver the therapeutic benefit of VNS in heart failure.

Does affective touch buffer emotional distress? Insights from subjective and physiological indices.

Affective touch, mediated by the activation of C-tactile afferents, has the potential to modulate affective states and physiological responses in situations of emotional distress, across the lifespan. The present study aims to disentangle psychophysiological mechanisms supporting autonomic and emotional self-regulation, focusing on the possible buffering role of affective touch. Childless adult participants (N = 92) were presented with videos of an infant babbling (positive scene) and an infant crying (emotionally negative scene), followed by a tactile stimulation either affective (brushing) or non-affective (tapping).

Effects of taVNS on physiological responses and cognitive performance during a mental stressor.

Transcutaneous auricular vagus nerve stimulation (taVNS) affects autonomic function and enhances cognitive performance by increasing vagal activation and central noradrenergic activity. Nevertheless, the impact of taVNS on acute mental stress remains largely unexplored. This study examined whether taVNS can mitigate the acute sympathetic stress response and improve cognitive performance during a socially evaluated version of the Paced Auditory Serial Addition Task (PASAT).

Background: Functional dyspepsia (FD) is often comorbid with sleep disturbance. Transcutaneous auricular vagal nerve stimulation (taVNS) is a new and non-invasive therapeutic option. This study aimed to investigate its effects and possible mechanisms on FD with sleep disturbance.

Persistent singultus (hiccups) can be distressing and challenging to manage in the postoperative setting. While pharmacological interventions such as metoclopramide are commonly used, their effectiveness is often limited. Gentian root (Gentiana lutea) contains intensely bitter secoiridoid compounds known to stimulate vagally mediated reflexes and has a long history of use for digestive complaints.

Background: Increased variability in central aortic systolic pressure (CASP) and pulse pressure (PP) are predictors of poor cardiovascular disease outcomes. Low-level tragus stimulation (LLTS) is a noninvasive method to reduce sympathetic tone via vagal afferent fibers. It is unknown if LLTS has a favorable effect on elevated variability in CASP and PP in patients with acute decompensated heart failure (HF) (ADHF).
