Background: Research productivity is a key criterion for applicant selection reported by residency program directors. Research volume reported on neurosurgery residency applications has risen steadily over the past decade. Objective: Perform retrospective bibliographic searches of successful applicants who matched into U.S. neurosurgery residency programs from 2011 to 2018, and assess the relationship between academic publishing and residency placement. Methods: Gender, MD/PhD status, U.S. News research ranking of medical school, and international medical graduate status (IMG) were determined for 1634 successful applicants from 2011 to 2018. Indexed publications before and after the start of residency were tabulated by Scopus®. Publication counts were stratified by first author, basic/clinical science, case reports, reviews, or other research. We then compared publishing trends across demographic variables and match cohorts. Results: Average pre-residency publications increased from 2.6 [1.7, 3.4] in 2011 to 6.5 [5.1, 7.9] in 2018. Men, PhD-holders, Top 20 and Top 40 U.S. medical school graduates, and IMGs had higher pre-residency publication counts overall. After stratifying by match cohort, however, there was no significant effect of gender on preresidency publications. Applicants matching into residency programs with highly ranked affiliated hospitals had significantly higher pre-residency publications. Conclusion: Publishing volume of successful neurosurgery applicants in the U.S. has risen recently and is associated with the stature of matched residency programs. Given the gap between verifiable and claimed research on residency applications, attention is needed to objectively evaluate research credentials in the selection process. The impending phase out of USMLE step 1 scores may increase emphasis on academic productivity.

BACKGROUND Although microsurgical resection (MR) remains the gold-standard for the treatment of symptomatic cavernous malformations, some authors have proposed the use of radiosurgical Gamma-Knife Surgery (GKS) for lesions that are deep or eloquent, such as those located in the brainstem. OBJECTIVE Here were analyze the literature regarding patient outcomes following MR or GKS for brain stem cavernous malformations. METHODS This study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for systematic literature review. A database search of PubMed, Scopus, Embase, and Web of Science was conducted in September 2019. This review included studies evaluating the outcomes of MR or GKS for cavernous malformations located in the brainstem. RESULTS Gross total resection was achieved in the majority of patients and effectively eliminated the risk of recurrent hemorrhage from the operative lesion in studies following the outcomes of MR. GKS reduces the annual hemorrhage rate for patients, although it does not eliminate the cavernous malformation. Both treatment modalities were effective in reducing prior symptomatology. Unlike resection, GKS only reduces the risk of future hemorrhage and does prevent it. CONCLUSIONS Both MR and GKS can improve or stabilize symptoms in patients. However, the therapeutic benefit of GKS may take months to years to take full-effect, resulting in a potential for subsequent hemorrhagic events. MR remains the best treatment option due to its ability to eliminate future bleeding events entirely and should be performed whenever gross total resection is possible.
