Impact of COVID-19 on Radiology Residency Selection Process: A Survey of Radiology Residency Programs in the US.

RATIONALE AND OBJECTIVES: Virtual residency interviews have become crucial in maintaining CDC-recommended precautionary measures throughout the ongoing COVID-era. However, scant literature exists regarding the direct impact the pandemic has had on the radiology program selection process, including preferred modalities of residency interviews and social media utilization. This survey aimed to understand how radiology programs adapted to changes in the 2020-2021 virtual application cycle. MATERIALS AND METHODS: A 32-question survey was distributed to 194 residency programs between July and August of 2021. Data were analyzed primarily by using descriptive statistics and Paired Student's T-testing. RESULTS: A total of 31 programs completed the survey, yielding a response rate of 16%. When queried about the perceived success of virtual interviews during the 2020-2021 application cycle, 21 programs (68%) said the new interview format was very successful. Twenty-seven of the programs (87%) believed they were able to adequately gauge applicants through virtual interviews. However, when surveyed about personal preferences for interviews, the responses were more evenly distributed between virtual (11/31, 35%) and in-person (14/31, 45%). Pre-COVID, the top three criteria programs used to rank candidates were USMLE Step 1 score (20/31, 65%), letters of recommendation (17/31, 55%), and MSPE (12/31, 39%). Within the virtual, COVID-19 era, these criteria remained statistically unchanged (p = 0.22): USMLE Step 1 score (21/31, 68%), letters of recommendation (17/31, 55%), and MSPE (14/31, 45%). About half of programs who had not previously utilized social media (12 of 23, 52%) created accounts, mostly via Twitter or Instagram. CONCLUSION: The primary findings indicate that programs perceived success with virtually interviewing and ranking applicants, the criteria to rank applicants remain unchanged despite the virtual environment, and programs' social media utilization increased.

Effects of brief chilling and desiccation on ion homeostasis in the central nervous system of the migratory locust, Locusta migratoria.

In insects, chilling, anoxia, and dehydration are cues to trigger rapid physiological responses enhancing stress tolerance within minutes. Recent evidence suggests that responses elicited by different cues are mechanistically distinct from each other, though these differences have received little attention. Further, the effects are not well studied in neural tissue. In this study, we examined how brief exposure to desiccation and chilling affect ion homeostatic mechanisms in metathoracic ganglion of the migratory locust, Locusta migratoria. Both desiccation and chilling enhanced resistance to anoxia, though only chilling hastened recovery from anoxic coma. Similarly, only chilling enhanced resistance to pharmacological perturbation of neuronal ion homeostasis. Our results indicate that chilling and desiccation trigger mechanistically distinct responses and, while both may be important for neuronal ion homeostasis, chilling has a larger effect on this tissue. SUMMARY STATEMENT: This is one of few studies to demonstrate the importance of the central nervous system in rapid acclimatory responses in insects.
