Readiness of Medical Students to Care for Diverse Patients: A Validated Assessment of Cross-Cultural Preparedness, Skills, and Curriculum.

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. Methods: Learners across 4 years of medical school participated in the cross-cultural care assessment, using a tool previously validated with resident physicians and modified for medical students. The survey assessed medical student perspectives on (1) preparedness, (2) skillfulness, and (3) educational curriculum and learning environment. Cross-sectional data were analyzed by class year, comparing trends between school years. Results: Of 700 possible survey responses, we received 260 (37% response rate). Fourth-year students had significantly higher scores than first-year students (p<0.05) for 7 of 12 preparedness items and 4 of 9 skillfulness items. Less than 50% of students indicated readiness to deliver cross-cultural care by their fourth year in 9 of 12 preparedness items and 6 of 9 skillfulness items. Respondents identified inadequate cross-cultural education as the primary barrier. Discussion: Medical students reported a lack of readiness to provide cross-cultural care, with self-assessed deficiencies persisting through the fourth year of medical school. Medical educators can use data from the cross-cultural care survey to longitudinally assess students and enhance curricular exposures where deficiencies exist. Optimizing cross-cultural education has the potential to improve the learning environment and overall patient care.

Enhancing biofeedback-driven self-guided virtual reality exposure therapy through arousal detection from multimodal data using machine learning.

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. However, creating such a VR environment and determining physiological indices of anxiety-induced arousal or distress is an open challenge. Environment modelling, character creation and animation, psychological state determination and the use of machine learning (ML) models for anxiety or stress detection are equally important, and multi-disciplinary expertise is required. In this work, we have explored a series of ML models with publicly available data sets (using electroencephalogram and heart rate variability) to predict arousal states. If we can detect anxiety-induced arousal, we can trigger calming activities to allow individuals to cope with and overcome distress. Here, we discuss the means of effective selection of ML models and parameters in arousal detection. We propose a pipeline to overcome the model selection problem with different parameter settings in the context of virtual reality exposure therapy. This pipeline can be extended to other domains of interest where arousal detection is crucial. Finally, we have implemented a biofeedback framework for VRET where we successfully provided feedback as a form of heart rate and brain laterality index from our acquired multimodal data for psychological intervention to overcome anxiety.

Creating opportunities to engage with prospective historically marginalized trainees with clinical simulation.

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. SiMfest is a two-hour simulation session presented annually (2017-2019) by our institution at the Student National Medical Association Annual Medical Education Conference. RESULTS: Over 800 students participated in SiMfest sessions over three years. Of the 461 participants who completed a survey after participation, 301 identified as female, and 382 indicated a racial category considered as historically marginalized in medicine-91% of whom identified as African American or Black. Thirty percent (n = 125) of respondents identified as pre-medical (e.g., undergraduate, post-baccalaureate) students and 69% (n = 289) identified as current medical students. Over 80% of students would recommend SiMfest to others. Additionally, 73% (n = 87) of pre-medical and 54% (n = 143) of medical students reported exposure to a previously unknown specialty. Thirty-three department representatives reported their SiMfest experience revealed new information about historically marginalized applicants that they may not have engaged with through the traditional application process but would be more likely to engage with in future diversity, equity, and inclusion initiatives. CONCLUSION: SiMfest harnessed our institution's high-quality training, personnel resources, and diversity, equity, and inclusion values to bring historically marginalized students in medicine and department leadership together to learn about one another and offer experiential learning. SiMfest may serve as a model for other institutions to draw on their strengths to develop innovative recruitment programs that promote the education and engagement of undergraduate and medical students from historically marginalized populations while simultaneously promoting diversity, equity, and inclusion culture change.

Disparities in access to translational research.

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. In fact, only 20% of randomized controlled studies published in high-impact oncology journals include subgroup analyses to assess differences in outcomes based on race or ethnicity.1 If effective interventions to decrease health disparities in research are to be implemented, it is critical to understand the multifactorial influences that create such differences. These are complex and include individual patient factors, family and social support, provider and organizational factors, as well as policy and community factors. Patient access to tertiary or quaternary care academic centers or designated cancer centers with the funding and resources to carry out translational research and knowledge of ongoing available research endeavors is often critical. Active community engagement and outreach and deep understanding of a particular health system's catchment area are necessary to increase both awareness and participation in clinical trials. Without significant progress in biomedical research patient recruitment, existing racial and ethnic health disparities will be challenging to overcome.

Strategies to Increase Racial and Ethnic Diversity in the Surgical Workforce: A State of the Art Review.

OBJECTIVE: To evaluate strategies to increase racial and ethnic diversity in the surgical workforce among trainees and faculty across surgical specialties. DATA SOURCES: Embase, OVID/Medline, and Web of Science Core Collection. REVIEW METHODS: A review of US-based, peer-reviewed articles examining the effect of targeted strategies on racial and ethnic diversity in the surgical workforce was conducted from 2000 to 2020 with the PRISMA checklist and STROBE tool. Studies without an outlined strategy and associated outcomes were excluded. Eleven studies met inclusion criteria and were completed in general surgery, orthopaedic surgery, and otolaryngology-head and neck surgery. CONCLUSIONS: Efforts to increase exposure to surgery through internship programs and required clerkships with efforts to improve mentorship were common (6 of 11 [54.5%] and 3 of 11 [27.3%] studies, respectively). Three (27.3%) studies aimed to diversify the recruitment and selection process for the residency match and faculty hiring, and 2 (18.2%) aimed to increase representation among trainees, faculty, and leadership through holistic review processes paired with departmental commitment. Outcome metrics included surgical residency applications for individuals underrepresented in medicine, interview and match rates, faculty hiring, measures of a successful academic surgical career, and leadership representation. All strategies were successful in increasing diversity in the surgical workforce. IMPLICATIONS FOR PRACTICE: A convincing yet limited body of literature exists to describe strategies and outcomes that address racial and ethnic diversity in the surgical workforce. While future inquiry is needed to move this field of interest forward, the evidence presented provides a framework for surgical residency programs/departments to develop approaches to increase racial and ethnic diversity.

The Value of Diversity, Equity, and Inclusion in Otolaryngology.

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. The more intentional our efforts, the more benefit to our patients, providers, staff, learners, and society.

Critical Components of Diversity Initiatives.

The importance of diversity is well established and holds important implications for workplace and physician-patient relationships. Evaluation of diversity statistics within otolaryngology-head and neck surgery reveals areas of deficiency that may be improved with targeted proactive approaches. This article provides a general overview of diversity within otolaryngology, highlights key components of diversity initiatives, and provides strategies for implementation.

The Clarion Call of the COVID-19 Pandemic: How Medical Education Can Mitigate Racial and Ethnic Disparities.

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. The authors first consider the roots of health care disparities in relation to the current pandemic. Then, they examine the importance of salient learning experiences that may inspire a commitment to championing social justice. Experiences in diverse communities can imbue medical students with a desire for lifelong learning and advocacy. The authors introduce a 3-pillar framework that consists of trust building, structural competency, and cultural humility. They discuss how these pillars should underpin educational efforts to improve social determinants of health. Effecting systemic change requires passion and resolve; therefore, perseverance in such efforts is predicated on learners caring about the structural inequities in housing, education, economic stability, and neighborhoods-all of which influence the health of individuals and communities.

Validation of an Objective Assessment Tool for Tonsillectomy in Otolaryngology Resident Training.

OBJECTIVE: Create and validate an objective structured assessment of technical skills (OSATS) for otolaryngology residents learning how to perform a tonsillectomy. STUDY DESIGN: Multicenter prospective longitudinal validation study. METHODS: A multi-institutional study at six tertiary academic otolaryngology residency programs from July 2009 to May 2012. Using the modified Delphi technique, a panel of pediatric otolaryngologists created a tonsillectomy task-based checklist (TBC) for a tonsil OSATS using a 5-point Likert-type scale. Residents were assessed by pediatric otolaryngology staff at the time of surgery with the TBC and a global rating scale. Procedure time, patient age, number of previously performed tonsillectomies, and surgical technique were also collected. RESULTS: One hundred sixty-seven tonsil OSATS were completed for 38 residents, and competency was recorded for 99 (59.2%). Residents scored as competent had performed significantly more previous tonsillectomies than those deemed noncompetent, 44.4 ± 35.6 and 13.5 ± 11.6, respectively (P < .001). The mean overall score on the tonsil TBC was 4.0 ± 0.8 and 2.6 ± 1.0 for competent and noncompetent, respectively (P < .001). Higher number of tonsillectomies performed and mean tonsil TBC score significantly increased the likelihood of competency (P < .001). Each additional tonsillectomy performed increased the likelihood of achieving competency by 6.3% (P = .006, 95% confidence interval (CI): 1.330-1.110), and each 1.0 point increase in mean tonsil TBC score increased the likelihood of competency by a factor of 2.71 (P = .006, 95% CI:1.330-5.513). There is a 95% likelihood of competency at 48 tonsillectomies or a tonsil TBC score of 4.91. CONCLUSION: The tonsil OSATS is a valid and feasible instrument to assess resident competency with tonsillectomy and provides timely objective feedback. LEVEL OF EVIDENCE: 4.

Disparities and ethical considerations for children with tracheostomies during the COVID-19 pandemic.

The COVID-19 pandemic is exacerbating longstanding challenges facing children with tracheostomies and their families. Myriad ethical concerns arising in the long-term care of children with tracheostomies during the COVID-19 pandemic revolve around inadequate access to care, healthcare resources, and rehabilitation services. Marginalized communities such as those from Black and Hispanic origins face disproportionate chronic illness because of racial and other underlying disparities. In this paper, we describe how these disparities also present challenges to children who are technology-dependent, such as those with tracheostomies and discuss the emerging ethical discourse regarding healthcare and resource access for this population during the pandemic.

A remnant planetary core in the hot-Neptune desert.

The interiors of giant planets remain poorly understood. Even for the planets in the Solar System, difficulties in observation lead to large uncertainties in the properties of planetary cores. Exoplanets that have undergone rare evolutionary processes provide a route to understanding planetary interiors. Planets found in and near the typically barren hot-Neptune 'desert'1,2 (a region in mass-radius space that contains few planets) have proved to be particularly valuable in this regard. These planets include HD149026b3, which is thought to have an unusually massive core, and recent discoveries such as LTT9779b4 and NGTS-4b5, on which photoevaporation has removed a substantial part of their outer atmospheres. Here we report observations of the planet TOI-849b, which has a radius smaller than Neptune's but an anomalously large mass of [Formula: see text] Earth masses and a density of [Formula: see text] grams per cubic centimetre, similar to Earth's. Interior-structure models suggest that any gaseous envelope of pure hydrogen and helium consists of no more than [Formula: see text] per cent of the total planetary mass. The planet could have been a gas giant before undergoing extreme mass loss via thermal self-disruption or giant planet collisions, or it could have avoided substantial gas accretion, perhaps through gap opening or late formation6. Although photoevaporation rates cannot account for the mass loss required to reduce a Jupiter-like gas giant, they can remove a small (a few Earth masses) hydrogen and helium envelope on timescales of several billion years, implying that any remaining atmosphere on TOI-849b is likely to be enriched by water or other volatiles from the planetary interior. We conclude that TOI-849b is the remnant core of a giant planet.

Visual-to-auditory sensory substitution alters language asymmetry in both sighted novices and experienced visually impaired users.

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). Reading, and language more generally, are typically lateralised to the left cerebral hemisphere. Yet, unlike symbolic written language, SSDs convert images to sound based on visuospatial properties, with the right cerebral hemisphere potentially having a role in processing such visuospatial data. Here we investigated whether there is a hemispheric bias in the processing of visual-to-auditory sensory substitution information and whether that varies as a function of experience and visual ability. We assessed the lateralization of auditory processing with two tests: a standard dichotic listening test and a novel dichotic listening test created using the auditory information produced by an SSD, The vOICe. Participants were tested either in the lab or online with the same stimuli. We did not find a hemispheric bias in the processing of visual-to-auditory information in visually impaired, experienced vOICe users. Further, we did not find any difference between visually impaired, experienced vOICe users and sighted novices in the hemispheric lateralization of visual-to-auditory information processing. Although standard dichotic listening is lateralised to the left hemisphere, the auditory processing of images in SSDs is bilateral, possibly due to the increased influence of right hemisphere processing. Auditory SSDs might therefore be equally effective with presentation to either ear if a monaural, rather than binaural, presentation were necessary.

Adultification of Black Children in Pediatric Anesthesia.

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. Outcome data included mask versus intravenous induction, midazolam premedication, child life consultation, and family member presence. Racial differences between all outcomes were assessed in the cohort using a multivariable logistic regression model. RESULTS: A total of 33,717 Caucasian and 3901 black children were eligible for the study. For the primary outcome, black children 10-14 years were 1.3 times more likely than Caucasian children to receive mask induction (adjusted odds ratio [AOR], 1.3; 95% confidence interval [CI], 1.1-1.6; P = .001). Child life consultation was poorly documented (<0.5%) and not analyzed. Black children <15 years of age were at least 31% less likely than Caucasians to have a family member present for induction (AOR range, 0.4-0.6; 95% CI range, 0.31-0.84; P < .010). Black children <5 years of age were 13% less likely than Caucasians to have midazolam given preoperatively (AOR, 0.9; 95% CI, 0.8-0.9; P = .012). CONCLUSIONS: This study suggests that disparities in strategies for mitigating anxiety in the peri-induction period exist and adultification may be 1 cause for this bias. Black children 10 to 14 years of age are 1.3 times as likely as their Caucasian peers to be offered inhalation induction to reduce anxiety. However, black children are less likely to receive premedication with midazolam in the perioperative period or to have family members present at induction. The cause of this difference is unclear, and further prospective studies are needed to fully understand this difference.

Safety of radiofrequency ablation for adenotonsillectomy after cochlear implantation.

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 8.5 ±â€¯1.95 years) with 7 functioning implants. Pre- and post-surgical impedance testing revealed all electrodes were within normal operating limits. There was no statistically significant difference between the mean pre and post-operative impedances in 5 of the 7 tested implants (P = 0.2-0.8). The other two implants showed statistically significant improvement in impedance values which were not clinically significant (P = 0.02 and P < 0.001). Speech perception was unchanged as was functional performance for all 7 tested implants. CONCLUSIONS: We found that radiofrequency ablation used in the oropharynx during adenotonsillectomy did not alter the integrity of the cochlear implant devices when assessed using electrode impedance testing, audiometry and speech perception evaluation. These results confirm those reported in previous in vitro studies and confirm the safety of radiofrequency ablation adenotonsillectomy for children who have undergone previous cochlear implant placement.

Synesthetic hallucinations induced by psychedelic drugs in a congenitally blind man.

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. The phenomenology of the induced hallucinations suggests that experiences acquired through other means, might not give rise to "visual" experiences in the phenomenological sense, but instead gives rise to novel experiences in the other functioning senses.

Other ways of seeing: From behavior to neural mechanisms in the online "visual" control of action with sensory substitution.

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. Online control of action is essential for many daily tasks such as pointing, grasping and navigating, and adapting to a sensory substitution device successfully requires extensive learning. Here we review the research on sensory substitution for vision restoration in the context of providing the means of online control for action in the blind or blindfolded. It appears that the use of sensory substitution devices utilizes the neural visual system; this suggests the hypothesis that sensory substitution draws on the same underlying mechanisms as unimpaired visual control of action. Here we review the current state of the art for sensory substitution approaches to object recognition, localization, and navigation, and the potential these approaches have for revealing a metamodal behavioral and neural basis for the online control of action.
