The authors compare the effects of central electroanalgesia and premedication in hypertensive stomatological patients, administered to prepare the patients to treatment. In contrast to premedication, central electroanalgesia normalized (stabilized) the arterial pressure and pulse rate and did not reduce the rate of reaction to a light stimulus.

Background: Our understanding of osteoarthritis (OA) has evolved from a degenerative disease to one in which low-grade, chronic inflammation plays a central role. In addition, evidence suggests that OA is accompanied by both peripheral and central nervous system sensitization that can cause pain. It has been demonstrated that transcutaneous vagus nerve stimulation (tVNS) can relieve pain, inflammation, and central sensitization in other conditions including fibromyalgia, pelvic pain, and headaches.

Background: Transcutaneous electrical stimulation after breast cancer surgery has been utilized for various purposes, but the full efficacy of this treatment approach on postoperative symptoms remains unclear.
Aim: This study aimed to answer the question: Does transcutaneous electrical nerve stimulation significantly impact postoperative patient outcomes in individuals undergoing breast cancer surgery?
Methods: A systematic review of randomized controlled trials was conducted. Because of the limited number of studies included, it was not feasible to perform a meta-analysis.
The effect of transcutaneous auricular vagus nerve stimulation on cardiovascular function in subarachnoid hemorrhage patients: A randomized trial.

Background: Subarachnoid hemorrhage (SAH) is characterized by intense central inflammation, leading to substantial post-hemorrhagic complications such as vasospasm and delayed cerebral ischemia. Given the anti-inflammatory effect of transcutaneous auricular vagus nerve stimulation (taVNS) and its ability to promote brain plasticity, taVNS has emerged as a promising therapeutic option for SAH patients. However, the effects of taVNS on cardiovascular dynamics in critically ill patients, like those with SAH, have not yet been investigated.

Transcutaneous auricular vagus nerve stimulation (taVNS) has been tested as a strategy to facilitate fear extinction learning based on the hypothesis that taVNS increases central noradrenergic activity. Four studies out of six found taVNS to enhance extinction learning especially at the beginning of extinction. Facilitatory effects of taVNS were mainly observed in US expectancy, less in fear-potentiated startle (FPS), and not in the skin conductance response (SCR).

Article Synopsis
- The study aimed to investigate how electroacupuncture (EA) impacts the inflammatory response in the brains of obese rats, potentially revealing mechanisms for obesity improvement.
- Male SD rats were divided into four groups (normal control, model, EA, sham-EA) and subjected to an 8-week high-fat diet to induce obesity; EA was applied to specific acupoints to measure various health indicators.
- Results showed significant increases in body mass, inflammatory markers, and hypothalamic protein levels in the obesity model group, but also some elevated levels of anti-inflammatory markers following EA, indicating a potential therapeutic effect.
