The mechanism of vasovagal syncope (VVS) is multifaceted and involves a delicate balance within the autonomic nervous system (ANS). This review delves into the complex interplay between the ANS and VVS, elucidating the pivotal role that autonomic imbalance plays in the pathophysiology of this condition. Through a comprehensive exploration of the sympathetic and parasympathetic branches of the ANS, this review provides insights into the mechanisms that underlie VVS. In addition, this article discusses established and emerging research on the management of VVS.

The burnout phenomenon is a subject of considerable interest due to its impact on both employee well-being and scientific inquiry. Workplace factors, both intrinsic and extrinsic, play a pivotal role in its development, often leading to job dissatisfaction and heightened burnout risk. Chronic stress and burnout induce significant dysregulation in the autonomic nervous system and hormonal pathways, alongside structural brain changes.

Autonomic dysfunction is a common and early complication among patients with systemic sclerosis, suggesting that it may play a role in the pathogenesis of the disease and be a potential target for therapeutic interventions. Although the true prevalence of autonomic dysfunction among patients with systemic sclerosis is still unclear, it is estimated that as many as 80% of patients may be affected. Autonomic dysfunction may lead to widespread multi-organ dysfunction through its effects on the cardiovascular system, gastrointestinal tract, urinary tract, sweat and salivary glands, and pupils.

Background And Aims: Identifying the haemodynamic mechanism of autonomic syncope is the essential pre-requisite for effective and personalized therapy aimed at preventing recurrences. The present study assessed the diagnostic efficacy of a two-step assessment.
Methods: Multicentre prospective, cross-sectional, observational study.
The effect of mortality salience and early-life maternal care on neuroendocrine, autonomic, and psychological stress responses.

Adverse early-life experiences alter the regulation of major stress systems such as the hypothalamic-pituitary-adrenal (HPA) axis. Low early-life maternal care (MC) has repeatedly been related to blunted cortisol stress responses. Likewise, an acutely increased awareness of mortality (mortality salience [MS]) also has been shown to blunt cortisol responses.

Facial nerve injuries lead to significant functional impairments and psychological distress for affected patients. Effective repair of these injuries remains a challenge. For longer nerve gaps, the regeneration outcomes after nerve grafting remain suboptimal due to limited sources and postoperative immune responses.
