To examine the experience of interracial anxiety among health professionals and how it may affect the quality of their interactions with patients from racially marginalized populations. We explored the influence of prior interracial exposure—specifically through childhood neighborhoods, college student bodies, and friend groups—on interracial anxiety among medical students and residents. We also examined whether levels of interracial anxiety change from medical school through residency.
Data Source
Web-based longitudinal survey data from the Medical Student Cognitive Habits and Growth Evaluation Study.
Study Design
We used a retrospective longitudinal design with four observations for each trainee. The study population consisted of non-Black US medical trainees surveyed in their 1st and 4th years of medical school and 2nd and 3rd years of residency. Mixed effects longitudinal models were used to assess predictors of interracial anxiety and assess changes in interracial anxiety scores over time.
Principal Findings
In total, 3155 non-Black medical trainees were followed for 7 years. Seventy-eight percent grew up in predominantly White neighborhoods. Living in predominantly White neighborhoods and having less racially diverse friends were associated with higher levels of interracial anxiety among medical trainees. Trainees' interracial anxiety scores did not substantially change over time; interracial anxiety was highest in the 1st year of medical school, lowest in the 4th year, and increased slightly during residency.
Conclusions
Neighborhood and friend group composition had independent effects on interracial anxiety, indicating that premedical racial socialization may affect medical trainees' preparedness to interact effectively with diverse patient populations. Additionally, the lack of substantial change in interracial anxiety throughout medical training suggests the importance of providing curricular tools and structure (e.g., instituting interracial cooperative learning activities) to foster the development of healthy interracial relationships. 相似文献
The purpose of this study was to evaluate the ability of alternate light source illumination to enhance bruises in pigmented skin. Previous work was limited to simulating bruises in non-pigmented (Caucasoid type) skin by injecting blood into pigskin. In this study, it was investigated if adding a layer of melanin to the surface of the skin would simulate pigmented skin. The study included evaluating the use of a filter that transmitted infrared light (wavelength greater than 720 nm) in place of the recommended visible light filters for the alternate light sources. The results obtained using pigskin with a layer of melanin were almost the same as results using the naturally pigmented goat ear. This indicated adding a layer of melanin could be used as a model for pigmented skin in this simulation of fresh bruising. Comparing the pigskin without melanin with pigskin with melanin revealed that the optimal light source to enhance the appearance of bruising, simulated by injection of blood, changed from violet to blue-green. Using the infrared transmitting filter resulted in greater enhancement than using the alternate light sources with their recommended visible light filter. The advantage of using the infrared transmitting filter was greater with the pigskin coated with melanin and the naturally pigmented goat ears than in the non-pigmented pigskin, however, the results remain to be validated using real bruises in naturally pigmented human skin.
Concern has been raised regarding the use of simethicone, a de‐foaming agent, during endoscopic procedures. Following reports of simethicone residue in endoscope channels despite high level disinfection, an endoscope manufacturer recommended that it not be used due to concerns of biofilm formation and a possible increased risk of microorganism transmission. However, a detailed mucosal assessment is essential in performing high‐standard endoscopic procedures. This is impaired by bubbles within the gastrointestinal lumen. The Gastroenterological Society of Australia's Infection Control in Endoscopy Guidelines (ICEG) Committee conducted a literature search utilizing the MEDLINE database. Further references were sourced from published paper bibliographies. Following a review of the available evidence, and drawing on extensive clinical experience, the multidisciplinary ICEG committee considered the risks and benefits of simethicone use in formulating four recommendations. Published reports have documented residual liquid or crystalline simethicone in endoscope channels after high level disinfection. There are no data confirming that simethicone can be cleared from channels by brushing. Multiple series report benefits of simethicone use during gastroscopy and colonoscopy in improving mucosal assessment, adenoma detection rate, and reducing procedure time. There are no published reports of adverse events related specifically to the use of simethicone, delivered either orally or via any endoscope channel. An assessment of the risks and benefits supports the continued use of simethicone during endoscopic procedures. Strict adherence to instrument reprocessing protocols is essential. 相似文献
In an article published in this issue of Cancer, D’Arcy et al link the incidence of cancer among recipients of solid organ transplantation (SOT) in the Scientific Registry of Transplant Recipients with data from regional and statewide cancer registries to examine cancer-specific mortality for common malignancies in SOT recipients. This analysis helps to illuminate the role of immune surveillance across a broad range of malignancies and compares the incidence of cancers due to virally mediated oncogenesis (lymphoma, squamous cell carcinoma of the aerodigestive epithelium, and hepatitis-induced liver cancer) with the incidence of other malignancies. The authors’ central finding is that cancer-specific mortality is significantly increased in SOT recipients in comparison with nontransplant recipients for multiple cancers, and the increased cancer incidence is not limited to the effects of viral oncogenesis. The authors document a significant increase in common epithelial malignancies that are currently treated with immune checkpoint antibodies, including melanoma, bladder cancer, colorectal cancer, cancers of the oral cavity/pharynx, kidney cancer, and lung cancer, and this supports the hypothesis that post-SOT immunosuppression affects immune surveillance in these cancers. Provocatively, the authors also document increases in the incidence and mortality of cancers not typically responsive to immune checkpoint therapies, including breast cancer and pancreatic cancer. The findings of D’Arcy et al suggest that immune surveillance controls oncogenesis and tumor progression in a broad range of malignancies and that breast cancer and pancreatic cancer could be sensitive to drugs targeting immune surveillance pathways other than those treated with currently Food and Drug Administration–approved antibodies to CTLA4 and PD-1/PD-L1. 相似文献
