Transcutaneous auricular vagus nerve stimulation (taVNS) is a novel neuromodulation application for vagal afferent stimulation. Owing to its non-invasive nature, taVNS is a potent therapeutic tool for a diverse array of diseases and disorders that ail us. Herein, we investigated taVNS-induced effects on neural activity of participants during visually induced motion sickness. 64-channel electroencephalography (EEG) recordings were obtained from 15 healthy participants in a randomized, within-subjects, cross-over design during sham and taVNS conditions. To assess motion sickness severity, we used the motion sickness assessment questionnaire (MSAQ). We observed that taVNS attenuated theta (4-8 Hz) brain activity in the right frontal, right parietal and occipital cortices when compared to sham condition. The total MSAQ scores, and central, peripheral and sopite MSAQ categorical scores were significantly lower after taVNS compared to sham. These findings reveal for the first time the potential therapeutic role of taVNS toward counter-motion sickness, and suggest that taVNS may be reliable in alleviating symptoms of motion sickness in real-time, non-pharmacologically.Clinical relevance- This suggests taVNS potential to offset motion sickness-induced nausea; which may be of translational value to counter e.g., chemotherapy-induced nausea.

University of Pittsburgh Medical Center Sports Medicine Concussion Program, Department of Orthopaedic Surgery, University of Pittsburgh, Pittsburgh, Pennsylvania.
Background: Factors associated with performance outside of a normative range on dynamic exertion test (EXiT) after sport-related concussion (SRC) remain unknown. This study examined the role of demographic and medical history factors on performance using minimal detectable change (MDC) cutoff scores in athletes being cleared to return to sport (RTS) from SRC.
Hypothesis: Older age, being female, and body mass index (BMI) ≥50th percentile would be associated with worse EXiT performance and with increased likelihood of falling outside the normative MDC score range.

Associate Professor and Chair, Department of Anesthesiology, Saitama Medical University Hospital, Moroyamacho Irumagun, Japan.
Background: Whether postoperative nausea and vomiting (PONV) contributes to increased postoperative pain (POP) remains unclear, although POP is reported to cause PONV.
Purpose: This study aimed to determine whether PONV following minor oral surgery (MOS) under general anesthesia increases POP.
Study Design, Setting, Sample: The researchers implemented a retrospective cohort study.

Introduction: Diving utilising closed circuit pure oxygen rebreather systems has become popular in professional settings. One of the hazards the oxygen diver faces is central nervous system oxygen toxicity (CNS-OT), causing potentially fatal convulsions. At the same time, divers frequently travel by boat, often suffering seasickness.
View Article and Find Full Text PDFObjective: To explore and validate effective eye movement features related to motion sickness (MS) through closed-track experiments and to provide valuable insights for practical applications.
Background: With the development of autonomous vehicles (AVs), MS has attracted more and more attention. Eye movements have great potential to evaluate the severity of MS as an objective quantitative indicator of vestibular function.

Cedars-Sinai Medical Center, Division of Otolaryngology-Head and Neck Surgery, Los Angeles, CA.
Introduction: GLP-1 receptor agonists (GLP-1 RAs) have gained traction in the management of obesity. There is limited literature on the implications of GLP-1 RAs in the field of otolaryngology.
Methods: We explore the association between GLP-1 RAs with eustachian tube dysfunction (ETD) and patulous ETD (PETD) by review of cases, literature, and the FDA adverse event database (FAERS).
