A computational model of motion sickness dynamics during passive self-motion in the dark
Exp Brain Res. 2024 Mar 15. doi: 10.1007/s00221-024-06804-z. Online ahead of print.ABSTRACTPredicting the time course of motion sickness symptoms enables the evaluation of provocative stimuli and the development of countermeasures for reducing symptom severity. In pursuit of this goal, we present an Observer-driven model of motion sickness for passive motions in the dark. Constructed in two stages, this model predicts motion sickness symptoms by bridging sensory conflict (i.e., differences between actual and expected sensory signals) arising from the Observer model of spatial orientation perception (stage 1) to Oman's mode...

Prevalence and associated factors of postoperative nausea and vomiting among adult patients undergoing elective surgery
CONCLUSION: The prevalence of this study is higher than studies conducted in the recent years. This result showed that the appropriate practice of PONV prophylactic regimens and anaesthesia management are required to decrease the risk of PONV.PMID:38463094 | PMC:PMC10923364 | DOI:10.1097/MS9.0000000000001678 (Source: Annals of Medicine)

Comparison of prophylaxis strategy for postoperative nausea and vomiting and its incidence before and after the implementation of 5-hydroxytryptamine 3 in surgical setting: a single-center, retrospective study
ConclusionThe availability of ondansetron increased the number of patients with adequate PONV prophylaxis, but did not decrease the incidence of PONV. (Source: Journal of Anesthesia)

Investigation of Pathogenesis and Otolithic Organ Responses in Sailors with Seasickness Using cVEMP
AbstractThere are different theories cited as the cause of Motion Sickness. Asymmetrical otolithic organ function is one of the etiology theories of motion sickness. In our study, the aim was to reveal whether there is a cause originating from the sacculocolic reflex pathway in the physiopathology of seasickness. The patient group included 15 man sailors with diagnosis of seasickness and the control group included 15 man sailors without seasickness in our study. Cervical evoked myogenic vestibular potential (cVEMP) findings were compared between the groups. In the right and left ears of sailors with seasickness, the mean l...

Sensors, Vol. 24, Pages 1046: Relationship between Car-Sickness Susceptibility and Postural Activity: Could the Re-Weighting Strategy between Signals from Different Body Sensors Be an Underlying Factor?
ne Cian Postural control characteristics have been proposed as a predictor of Motion Sickness (MS). However, postural adaptation to sensory environment changes may also be critical for MS susceptibility. In order to address this issue, a postural paradigm was used where accurate orientation information from body sensors could be lost and restored, allowing us to infer sensory re-weighting dynamics from postural oscillation spectra in relation to car-sickness susceptibility. Seventy-one participants were standing on a platform (eyes closed) alternating from static phases (proprioceptive and vestibular sensors providing ...

Visually induced symptoms questionnaire (VISQ): A subjective evaluation method for biomedical effects induced by stereoscopic 3D video
Appl Ergon. 2024 Feb 4;117:104238. doi: 10.1016/j.apergo.2024.104238. Online ahead of print.ABSTRACTThe purpose of this paper is to establish an easy-to-use questionnaire for subjective evaluations of visually induced motion sickness (VIMS) and visual fatigue caused by stereoscopic 3D (s3D) images. We reviewed previously used questionnaires and extracted 51 important subjective evaluation items from them. We then recruited 251 participants to observe 3D images designed to easily induce sickness or visual fatigue, and we asked them to respond to the 51 items. As a result of exploratory factor analysis, four factors were ext...

The Association of Guideline-Directed Prophylaxis With Postoperative Nausea and Vomiting in Adult Patients: A Single-Center, Retrospective Cohort Study
CONCLUSIONS: Guideline-directed PONV prophylaxis is associated with a modest reduction in PONV, although this effect is small and heterogeneous on the absolute scale. We found evidence for a differential association between adequate prophylaxis and PONV across the guideline-defined risk spectrum, with diminution in patients at very high predicted preoperative risk. While patient-specific benefit was heterogenous, most patients had reasonably high predicted probabilities of absolute benefit from a guideline-directed strategy. Further assessment of these associations in a multicenter setting, with more robust investigation o...

The role of vision in sensory integration models for predicting motion perception and sickness
In conclusion, the SVCI model with visual rotation velocity feedback is the current preferred option to design vehicle control algorithms for motion sickness reduction, while the MSOM best predicts perception. A unified model that jointly captures perception and motion sickness remains to be developed.PMID:38253934 | DOI:10.1007/s00221-023-06747-x (Source: Experimental Brain Research)

A Real Environment Based Virtual Reality Psychosocial Treatment May Help Patients with Schizophrenia to Increase Social Functioning: A Preliminary Study
CONCLUSION: In this preliminary study, we discovered that realenvironment- based VR-PTP is effective for improving the social skills of patients with schizophrenia. Cognitive enhancement programs and psychosocial functionality therapies may be carried out using virtual reality in the near future.
