Increasing Applicant Engagement During the 2020-2021 Virtual Residency Interview Cycle and Beyond: The Dartmouth-Hitchcock Radiology Residency Video Project.

RATIONALE AND OBJECTIVES: To explore the effectiveness of the video medium and YouTube platform in conveying residency program and community information to prospective applicants during the 2020-2021 virtual residency interview cycle. To garner insights on the virtual-only residency interview experience and our video-centered approach through survey data collected from interviewing candidates for potential implementation in future application cycles. MATERIALS AND METHODS: 13 custom content videos were produced highlighting our radiology residency program and uploaded onto a newly created YouTube channel and the institutional website during the late summer through fall of the 2020-2021 residency interview cycle. Feedback on the videos was generated using YouTube analytics and an anonymous 10-question survey sent to interviewing candidates. RESULTS: As of September 29, 2021, the date when residency programs could begin reviewing ERAS applications for the 2021-2022 cycle, the videos amassed 4487 views with over 149 hours' worth of material viewed. 57 of 114 interviewed candidates responded to the survey. Feedback was overwhelmingly positive with 84% of respondents agreeing that the videos positively influenced their decision to apply to our program, 77% of respondents judging our video-based format to be overall more effective in delivering residency program information than text-based media (website, email etc.), and 86% feeling adequately informed about the program through the virtual interview process and provided electronic resources. 79% of respondents felt our videos to be more informative than the resources from other radiology programs encountered during the interviewing cycle. Finally, a majority 72% of respondents are open to virtual interviewing in the future. CONCLUSIONS: Our program's video-centered approach was one of many creative media solutions employed by residency programs across the nation to help make virtual interviewing an adequate replacement to the traditional in-person interviewing experience. While further investigation is needed to determine which methods communicate residency program information best in the virtual setting, our initial experience and data show the video-centered approach to be overwhelmingly positive with applicants and at a minimum, we've established a baseline process and aesthetic for others to improve upon.

Urinary Iodine, Perchlorate, and Thiocyanate Concentrations in U.S. Lactating Women.

BACKGROUND: Iodine is an essential micronutrient for thyroid hormone production. Adequate iodine intake and normal thyroid function are important during early development, and breastfed infants rely on maternal iodine excreted in breast milk for their iodine nutrition. The proportion of women in the United States of childbearing age with urinary iodine concentration (UIC) <50 µg/L has been increasing, and a subset of lactating women may have inadequate iodine intake. UIC may also be influenced by environmental exposure to perchlorate and thiocyanate, competitive inhibitors of iodine transport into thyroid, and lactating mammary glands. Data regarding UIC in U.S. lactating women are limited. To adequately assess the iodine sufficiency of lactating women and potential associations with environmental perchlorate and thiocyanate exposure, we conducted a multicenter, cross-sectional study of urinary iodine, perchlorate, and thiocyanate concentrations in healthy U.S. lactating women. METHODS: Lactating women ≥18 years of age were recruited from three U.S. geographic regions: California, Massachusetts, and Ohio/Illinois from November 2008 to June 2016. Demographic information and multivitamin supplements use were obtained. Iodine, perchlorate, and thiocyanate levels were measured from spot urine samples. Correlations between urinary iodine, perchlorate, and thiocyanate levels were determined using Spearman's rank correlation. Multivariable regression models were used to assess predictors of urinary iodine, perchlorate, and thiocyanate levels, and UIC <100 µg/L. RESULTS: A total of 376 subjects (≥125 from each geographic region) were included in the final analyses [mean (SD) age 31.1 (5.6) years, 37% white, 31% black, and 11% Hispanic]. Seventy-seven percent used multivitamin supplements, 5% reported active cigarette smoking, and 45% were exclusively breastfeeding. Median urinary iodine, perchlorate, and thiocyanate concentrations were 143 µg/L, 3.1 µg/L, and 514 µg/L, respectively. One-third of women had UIC <100 µg/L. Spot urinary iodine, perchlorate, and thiocyanate levels all significantly positively correlated to each other. No significant predictors of UIC, UIC <100 µg/L, or urinary perchlorate levels were identified. Smoking, race/ethnicity, and marital status were significant predictors of urinary thiocyanate levels. CONCLUSION: Lactating women in three U.S. geographic regions are iodine sufficient with an overall median UIC of 143 µg/L. Given ubiquitous exposure to perchlorate and thiocyanate, adequate iodine nutrition should be emphasized, along with consideration to decrease these exposures in lactating women to protect developing infants.
