Numerous sub-cellular through system-level disturbances have been identified in over 1300 articles examining the superoxide dismutase-1 guanine 93 to alanine (SOD1-G93A) transgenic mouse amyotrophic lateral sclerosis (ALS) pathophysiology. Manual assessment of such a broad literature base is daunting. We performed a comprehensive informatics-based systematic review or ‘field analysis’ to agnostically compute and map the current state of the field. Text mining of recaptured articles was used to quantify published data topic breadth and frequency. We constructed a nine-category pathophysiological function-based ontology to systematically organize and quantify the field’s primary data. Results demonstrated that the distribution of primary research belonging to each category is: systemic measures an motor function, 59%; inflammation, 46%; cellular energetics, 37%; proteomics, 31%; neural excitability, 22%; apoptosis, 20%; oxidative stress, 18%; aberrant cellular chemistry, 14%; axonal transport, 10%. We constructed a SOD1-G93A field map that visually illustrates and categorizes the 85% most frequently assessed sub-topics. Finally, we present the literature-cited significance of frequently published terms and uncover thinly investigated areas. In conclusion, most articles individually examine at least two categories, which is indicative of the numerous underlying pathophysiological interrelationships. An essential future path is examination of cross-category pathophysiological interrelationships and their co-correspondence to homeostatic regulation and disease progression.
more interviews because they were virtual; only 25.3% (n ¼ 19) applied to more diverse geographic locations. Perceived advantages include saving money (96%), saving time (45.3%), and avoiding COVID-19 transmission risks (42.7%). Top limitations include the inability to observe the interactions between faculty, residents, and staff (61.3%), difficulty comparing programs (57.3%), and less exposure to current residents and faculty (57.3%). Despite demographic differences, interviewees were generally in agreement with no statistically significant differences in responses.
CONCLUSION:The sudden shift to virtual interviews presented unique challenges and opportunities. The inability to observe interactions and meet in person with future attendings and residents was a significant dissatisfier. Beyond COVID-19, efforts to reduce interview costs and increase accessibility will need to be balanced against the intangible benefit of human interaction and observing a program's culture.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
