Article Synopsis
  • Self-guided Virtual Reality Exposure Therapy (VRET) has been shown to effectively reduce Public Speaking Anxiety (PSA) and heart rate, indicating lower physiological arousal in socially anxious individuals.
  • The study involved 72 participants with high social anxiety who were divided into two groups: one receiving VRET with biofeedback on heart rate and brain activity, and the other receiving VRET alone.
  • Results indicated that both groups experienced improvements in social anxiety, but the biofeedback group exhibited a more consistent reduction in physiological arousal and greater decreases in self-reported anxiety levels during sessions.

Introduction: Effective cross-cultural care is foundational for mitigating health inequities and providing high-quality care to diverse populations. However, medical school teaching practices vary widely, and learners have limited opportunities to develop these critical skills. To understand the current state of cross-cultural education and to identify potential opportunities for improvement, we disseminated a validated survey instrument among medical students at a single institution.

Virtual reality exposure therapy (VRET) is a novel intervention technique that allows individuals to experience anxiety-evoking stimuli in a safe environment, recognise specific triggers and gradually increase their exposure to perceived threats. Public-speaking anxiety (PSA) is a prevalent form of social anxiety, characterised by stressful arousal and anxiety generated when presenting to an audience. In self-guided VRET, participants can gradually increase their tolerance to exposure and reduce anxiety-induced arousal and PSA over time.

Background: Recruiting a diverse group of medical students, house officers, and faculty in medicine is challenging-particularly for predominantly white, midwest institutions that may not be racially or ethnically diverse.

Purpose: To evaluate a novel clinical simulation program, SiMfest, for recruiting house officers from historically marginalized populations to our institution to demonstrate our leadership's commitment to high-quality education and recruitment of these students to enhance diversity in academic medicine.

Methods: The Office for Health Equity and Inclusion, institutional leadership, and clinical department chairs developed a novel and engaging series of clinical simulations, SiMfest, to engage the pipeline of historically marginalized trainees and demonstrate our leadership's commitment to high-quality education.

Translational research describes the process of applying observations and scientific discoveries made in the laboratory to clinical applications that can improve the health of individual patients, most often through clinical trials. To apply the findings of translational research studies to the broader population, the study population must accurately reflect the group of patients afflicted by a particular disease. Yet, it is well known that significant disparities exist for underrepresented groups and lower socioeconomic populations in clinical trials.

Diversity impacts performance of our teams, fosters innovation, and improves outcomes of our patients in otolaryngology head and neck surgery. In addition to the moral imperative, increasing the otolaryngology diversity workforce will decrease health care disparities while equity and justice can increase the culture humility to take care of an increasingly diverse patient population. To move toward justice, otolaryngology departments need to end biases in faculty hiring, development, research evaluations, and publication practices.

Self-guided virtual-reality exposure therapy (VRET) is a psychological intervention that enables a person to increase their own exposure to perceived threat. Public-speaking anxiety (PSA) is an anxiety-provoking social situation that is characterized by fear of negative evaluation from an audience. This pilot study aimed to determine whether self-guided VRET (1) increases exposure to PSA-specific virtual social threats, and (2) reduces anxiety, arousal, heartrate and PSA over repeated exposure.

Public health crises palpably demonstrate how social determinants of health have led to disparate health outcomes. The staggering mortality rates among African Americans, Native Americans, and Latinx Americans during the COVID-19 pandemic have revealed how recalcitrant structural inequities can exacerbate disparities and render not just individuals but whole communities acutely vulnerable. While medical curricula that educate students about disparities are vital in rousing awareness, it is experience that is most likely to instill passion for change.

Visual-to-auditory sensory substitution devices (SSDs) provide improved access to the visual environment for the visually impaired by converting images into auditory information. Research is lacking on the mechanisms involved in processing data that is perceived through one sensory modality, but directly associated with a source in a different sensory modality. This is important because SSDs that use auditory displays could involve binaural presentation requiring both ear canals, or monaural presentation requiring only one - but which ear would be ideal? SSDs may be similar to reading, as an image (printed word) is converted into sound (when read aloud).

Background: Unconscious racial bias in anesthesia care has been shown to exist. We hypothesized that black children may undergo inhalation induction less often, receive less support from child life, have fewer opportunities to have a family member present for induction, and receive premedication with oral midazolam less often.

Methods: We retrospectively collected data on those <18 years of age from January 1, 2012 to January 1, 2018 including age, sex, race, height, weight, American Society of Anesthesiologists (ASA) physical status, surgical service, and deidentified anesthesiology attending physician.

Objective: While a cadaveric animal study has suggested that radiofrequency ablation can be safely used in patients with cochlear implants, no in vivo studies have been published to confirm that radiofrequency ablation does not alter the integrity of the cochlear implant device.

Methods: Cochlear implant impedance and functional performance were studied through a prospective case series in five children with seven functioning multichannel implants before and after radiofrequency ablation adenotonsillectomy.

Results: There were 4 females and 1 male patient, aged 6-10 years (mean 8.

This case report offers rare insights into crossmodal responses to psychedelic drug use in a congenitally blind (CB) individual as a form of synthetic synesthesia. BP's personal experience provides us with a unique report on the psychological and sensory alterations induced by hallucinogenic drugs, including an account of the absence of visual hallucinations, and a compelling look at the relationship between LSD induced synesthesia and crossmodal correspondences. The hallucinatory experiences reported by BP are of particular interest in light of the observation that rates of psychosis within the CB population are extremely low.

Vision is the dominant sense for perception-for-action in humans and other higher primates. Advances in sight restoration now utilize the other intact senses to provide information that is normally sensed visually through sensory substitution to replace missing visual information. Sensory substitution devices translate visual information from a sensor, such as a camera or ultrasound device, into a format that the auditory or tactile systems can detect and process, so the visually impaired can see through hearing or touch.

A critical task for the brain is the sensory representation and identification of perceptual objects in the world. When the visual sense is impaired, hearing and touch must take primary roles and in recent times compensatory techniques have been developed that employ the tactile or auditory system as a substitute for the visual system. Visual-to-auditory sonifications provide a complex, feature-based auditory representation that must be decoded and integrated into an object-based representation by the listener.

A stridulous, dysphonic cry with no external signs of trauma is a unique and unusual presenting sign for physical abuse. We report a previously healthy neonate with unremarkable birth history and medical history who presented with stridor and hypopharyngeal perforation due to physical abuse. This case highlights the need for further evaluation for traumatic injuries in the setting of unexplained new-onset stridor and consideration of physical abuse in the differential diagnosis.

Sensory substitution devices such as The vOICe convert visual imagery into auditory soundscapes and can provide a basic 'visual' percept to those with visual impairment. However, it is not known whether technical or perceptual limits dominate the practical efficacy of such systems. By manipulating the resolution of sonified images and asking naïve sighted participants to identify visual objects through a six-alternative forced-choice procedure (6AFC) we demonstrate a 'ceiling effect' at 8 x 8 pixels, in both visual and tactile conditions, that is well below the theoretical limits of the technology.
