Leveraging Social Media and Web Presence to Discuss and Promote Diversity, Equity, and Inclusion in Radiology.

PURPOSE: This article seeks to better understand how radiology residency programs leverage their social media presences during the 2020 National Residency Match Program (NRMP) application cycle to engage with students and promote diversity, equity, and inclusion to prospective residency applicants. METHODS: We used publicly available information to determine how broad a presence radiology programs have across specific platforms (Twitter [Twitter, Inc, San Francisco, California], Facebook [Facebook, Inc, Menlo Park, California], Instagram [Facebook, Inc], and website pages) as well as what strategies these programs use to promote diversity, equity, and inclusion. RESULTS: During the 2020 NRMP application cycle, radiology residency programs substantially increased their social media presence across the platforms we examined. We determined that 29.3% (39 of 133), 58.9% (43 of 73), and 29.55% (13 of 44) of programs used Twitter, Instagram, and Facebook, respectively; these accounts were established after an April 1, 2020, advisory statement from the NRMP. Program size and university affiliation were correlated with the degree of social media presence. Those programs using social media to promote diversity, equity, and inclusion used a broad but similar approach across programs and platforms. CONCLUSION: The events of 2020 expedited the growth of social media among radiology residency programs, which subsequently ushered in a new medium for conversations about representation in medicine. However, the effectiveness of this medium to promote meaningful expansion of diversity, equity, and inclusion in the field of radiology remains to be seen.

Bridging the Equity Gap.

OBJECTIVE. This article introduces key concepts of inequity as they apply to interventional radiology, from both the patient and the physician perspectives, to ultimately improve the health care of all patients. CONCLUSION. By directing society's efforts toward addressing health care disparities, our specialty may begin to establish trust and partnerships with populations that are disproportionately affected and those that have been historically exploited and disenfranchised by medicine in the name of innovation. Although we may look to close the equity gap by understanding health care disparities as they pertain to our patient populations, a closer examination of barriers of entry into medicine for underrepresented minorities reveals numerous disparities across race, sexual orientation, and socioeconomic status.

Assessment and optimization of electroporation-assisted tumoral nanoparticle uptake in a nude mouse model of pancreatic ductal adenocarcinoma.

Pancreatic ductal adenocarcinoma (PDAC) is a particularly lethal form of cancer. In 2012, the incidence of PDAC was 43,920. Five-year survival for patients with PDAC is around 6%, regardless of staging, making PDAC one of the deadliest forms of cancer. One reason for this dismal prognosis is chemoresistance to the current first-line therapy, gemcitabine. There are multiple factors that contribute to the chemoresistance observed in pancreatic cancer. Among them, desmoplasia has been increasingly seen as a significant contributor to chemoresistance. To overcome desmoplastic chemoresistance, several novel methods of treatment have been developed. Electroporation is one such novel treatment. High electrical fields are applied to cells to create pores that increase cell permeability. It has been previously demonstrated that electroporation enhances the therapeutic efficacy of anticancer drugs in pancreatic tumor models. Nanoparticle-based drug delivery systems constitute a second novel method to overcome desmoplastic chemoresistance. Due to their intrinsic design advantages, nanoparticles have been shown to increase the effectiveness of chemotherapeutic agents, while further reducing or even eliminating side effects. To date, there have been no studies evaluating the cumulative effect of combining both nanoparticle and electroporation strategies to overcome chemoresistance in PDAC. Our preliminary studies assessed the in vitro and in vivo uptake of doxorubicin-loaded iron oxide nanoparticles as a function of electroporation voltage and timing of administration in pancreatic adenocarcinoma cells. Our studies demonstrated that addition of electroporation to administration of nanoparticles significantly increased the amount of intracellular iron oxide nanoparticle uptake by a PANC-1 cell line in an athymic nude mouse model of PDAC. Further, electroporation-assisted nanoparticle uptake could be significantly altered by changing the timing of application of electroporation.
