Equity, diversity, and inclusion in academic American otolaryngology faculty: an elusive dream.

We analyze gender and racial disparities in academic otolaryngology from 2007 to 2018 in the United States (US). A cross-sectional retrospective analysis was done using data from the American Association of Medical Colleges. The distribution of gender and race, academic ranks, tenure tracks, and degrees was reported. The total number of otolaryngologists increased from 1,490 to 2,239, where 53 percent were females. All races experienced an increase; however, Whites and Asians had a greater increase compared to Black and Hispanics. Regarding percentages at different ranks, White were the majority (>50 percent) in every category. As for tenure, the general trend was a decrease in the total number of tenured physicians from 327 in 2007 to 318 in 2018, where Black, Hispanic, and Asian tenured physicians increased, while White tenured physicians decreased. White male otolaryngologists were the majority for every subgroup (>60 percent), whereas Black faculty made up less than 1 percent of tenured category. Female representation gradually increased for all levels of tenure. As for all degrees, Whites were the majority for all levels of education (>60 percent). There were some improvements in the representations for the females in all and Asians on the tenure track. However, progress for the URM remains an elusive dream.

Hypothalamic beta-endorphin neurons suppress preneoplastic and neoplastic lesions development in 1,2-dimethylhydrazine induced rat colon cancer model.

In recent years, experimental studies demonstrated negative impacts of impaired body stress response on colonic pathologies. In this study, we tested if reducing body stress response by the use of ß-endorphin (BEP) neuronal transplants in the hypothalamus suppresses pre-neoplastic and neoplastic lesions. Colon cancer was induced by injecting 1,2-dimethylhydrazine (DMH) for sixteen weeks in Sprague Dawley rats with BEP neuron transplants or control neuron transplants, and their colonic histopathologies, colon tissue levels of pro-inflammatory cytokines and epithelial-mesenchymal transition (EMT) proteins and splenic levels of cytotoxic proteins were measured. Our results revealed that DMH induced tumors in colon at 100% incidence in control rats but failed to induce colonic tumors in 70% of animal with BEP neuronal transplants. The mean volume of tumor at the colon was smaller in BEP neurons transplanted rats than those in controls. Histopathologies of colon tissues revealed that BEP neurons transplanted animals had lesser tissue lesions such as aberrant crypt foci (ACF) and adenocarcinoma development in the colon than those in control groups. Immunohistochemical and western blot analyses identified reduced expression of Ki-67, TNF-α and NF-κB nuclear translocation in colonic tissues of BEP neurons transplanted rats than those in controls. BEP neurons transplanted rats also showed reduced expressions of transcription factors linked to EMT like Snail, Twist, and N-cadherin, but increased the levels of an epithelial cell marker E-cadherin in colon tissue. Furthermore, splenic NK cells cytolytic proteins such as perforin, granzyme B and IFN-γ levels in BEP neurons transplanted rats were higher than those in control rats. These data suggest that BEP neuron transplants suppress the growth and progression of colonic tumors possibly by decreasing inflammatory mileu and EMT via activation of innate immune responses.
