Personal Preparation of Medical Students for the Human Dissection Experience: A Systematic Review.

Anatomical dissection is a cause of distress for many medical students. Explicit pedagogical strategies are important in reducing student distress and supporting their personal development. A systematic review of PubMed, Ovid, PsycINFO, and Web of Science databases was conducted to examine quantitative data regarding medical school interventions to reduce the negative psychological and moral impact of anatomical dissection on medical students. Of 1189 unique abstracts, 14 papers met screening criteria. Student distress decreased with the use of educational audiovisual materials and graded exposure to donor bodies. Educational lectures, memorial ceremonies, and utilization of background music had mixed results.

The Impact of Delay in Treatment on Survival in Surgically Managed Sinonasal Undifferentiated Carcinoma.

Background Sinonasal undifferentiated carcinoma (SNUC) is a rare, aggressive malignancy with a poor prognosis, and multimodal therapy is the standard of care. We sought to characterize treatment delays in SNUC managed with surgery and adjuvant radiation and to determine the impact on survival using the National Cancer Database (NCDB). Methods This was a retrospective, population-based cohort study of patients with SNUC between 2004 and 2016 in the NCDB. The intervals of diagnosis to surgery (DTS), surgery to radiation (SRT), and radiation duration (RTD) were examined. Recursive partitioning analysis (RPA) was performed to identify the variables with the greatest impact on survival. The association between treatment delay and overall survival (OS) was then assessed using multivariate Cox proportional hazards regression. Results Of 173 patients who met inclusion criteria, 65.9% were male, average age at diagnosis was 56.6 years, and 5-year OS was 48.1%. Median durations of DTS, SRT, and RTD were 18, 43, and 46 days, respectively. Predictors of treatment delay included Black race, government insurance excluding Medicare/Medicaid, and positive margins. RPA-derived optimal thresholds were 29, 28, and 38 days for DTS, SRT and RTD, respectively. On multivariate analysis, positive margins (hazard ratio [HR]: 4.82; 95% confidence interval [CI]: 2.28-10.2) and DTS less than 29 days (HR: 2.41; 95% CI: 1.23-4.73) were associated with worse OS. Conclusion Our results likely reflect the aggressive nature of the disease with surgeons taking more invasive disease to the operating room more quickly. Median treatment intervals described may serve as relevant national benchmarks.

Use of biologics for treatment of autoimmune inner ear disease.

OBJECTIVE: Biologic medications are novel therapeutics in the treatment of Autoimmune Inner Ear Disease (AIED), an etiology of Sensorineural Hearing Loss (SNHL). The goal of this study is to review the currently available literature on the efficacy of biologic medications on autoimmune-mediated hearing loss and associated symptomology among patients with AIED. METHODS: A systematic review of Pubmed, Scopus, Cochrane, and Web of Science databases was conducted to identify studies investigating the impact of biologic medications on hearing outcomes. Bias assessment was independently conducted by three authors and studies were stratified based on risk of bias. RESULTS: Of 174 unique abstracts screened, 12 articles met inclusion criteria for formal review. One randomized control trial, seven prospective cohort studies, and four retrospective cohort studies were included. Seven biologic medications, Etanercept, Infliximab, Adalimumab, Golimumab, Rituximab, Anakinra, and Canakinumab, were identified targeting three unique molecular targets, TNF-α, CD20, and IL-1. CONCLUSION: The effects of biologic medications in treating SNHL was highly variable without clear efficacy of a drug or drug category, likely due to rarity of disease, multifactorial etiologies of AIED, and cohort heterogeneity. However, several medications alleviate symptoms associated with AIED, such as vertigo and tinnitus. While biologic medications may be promising therapeutics in AIED patients, the evidence is currently inconclusive. Large-scale randomized control trials and prospective cohort reviews are required to establish the efficacy of biologic medications in treating hearing loss.

Sociodemographic disparities in pediatric cochlear implantation outcomes: A systematic review.

OBJECTIVES: To determine the impact of sociodemographic factors on post-operative performance outcomes among PCI recipients across the world. METHODS: A qualitative systematic review of PubMed, Scopus, Web of Science, and Embase was undertaken for studies analyzing the association of sociodemographic factors with measures of PCI outcomes published before July 18, 2021. Study quality assessment tools from the National Institutes of Health (NIH) were used to assess for risk of bias. RESULTS: Out of 887 unique abstracts initially retrieved, 45 papers were included in the final qualitative systematic review. Sociodemographic disparities in PCI outcomes from 4702 PCI recipients were studied in 19 countries, with 14 studies conducted in the United States of America, published within the years of 1999 to 2021. Parental education and socioeconomic status (e.g. income) were the most investigated disparities in PCI outcomes with 24 and 17 identified studies, respectively. CONCLUSION: Socioeconomic status was a consistently reported determinant of PCI outcomes in the USA and elsewhere, and parental education, the most reported disparity, consistently impacted outcomes in countries outside the USA. This study is limited by our inability to perform a meta-analysis given the lack of standardization across measures of sociodemographic variables and assessment measures for PCI outcomes. Future studies should address the literature gap on racial and ethnic disparities among PCI outcomes and use standardized measures for sociodemographic variables and PCI outcomes to facilitate meta-analyses on the topic. Targeting the mechanisms of these disparities may mitigate the impact of the sociodemographic factors on PCI outcomes.
