RESUMO
PURPOSE: Neuronavigation, explored as an intra-operative adjunct for brain tumor surgery three decades ago, has become globally utilized with a promising upward trajectory. This study aims to chart its success from idea to adoption and evolution within the US and globally. METHODS: A three-pronged methodology included a systematic literature search, impact analysis using NIH relative citation ratio (RCR) and Altmetric scores, and assessment of patent holdings. Data was dichotomized for US and international contexts. RESULTS: The first neuronavigation publication stemmed from Finland in 1993, marking its inception. Over three decades, the cumulative number of 323 studies, along with the significantly increasing publication trend (r = 0.74, p < 0.05) and distribution across 34 countries, underscored its progressive and global adoption. Neuronavigation, mostly optical systems (58%), was utilized in over 19,000 cases, predominantly for brain tumor surgery (84%). Literature impact showed a robust cumulative median RCR score surpassing that for NIH-funded studies (1.37 vs. 1.0), with US studies having a significantly higher median RCR than international (1.71 vs. 1.21, p < 0.05). Technological evolution was characterized by adjuncts, including micro/exo/endoscope (21%), MRI (17%), ultrasound (10%), and CT (7%). Patent analysis demonstrated academic and industrial representation with an interdisciplinary convergence of medical and computational sciences. CONCLUSION: Since its inception thirty years ago, neuronavigation has been adopted worldwide, and it has evolved with adjunct technology integration to enhance its meaningful use. The current neuronavigation innovation pipeline is progressing, with academic and industry partnering to advance its further application in treating brain tumor patients.
RESUMO
PURPOSE: Lateral interbody fusion (LIF) is an increasingly popular minimally-invasive spine procedure. This study identifies notable trends in LIF literature and provides a detailed review of the bibliometric aspects of the top 100 most-cited articles. METHODS: Articles were queried from the Web of Science database. Inclusion criteria consisted of peer-reviewed articles, full-text availability, and LIF focus. Network analysis including co-authorship mapping and bibliographic coupling were complemented by trend analysis to determine prominent contributors and themes. Analyses were conducted using VOSviewer and Bibliometrix (RStudio). RESULTS: There has been a rapid increase in LIF publication and citation count since 1998. Leading journals were Spine (n = 24), Journal of Neurosurgery Spine (n = 22), and European Spine Journal (n = 12). NuVasive funded the most publications (n = 17), followed by DePuy Synthes Spine (n = 4). The United States was the most represented country (n = 81); however, trend analysis suggests a steadily growing international contribution. The most prolific author was J.S. Uribe (n = 16), followed by a tie in second place by E. Dakwar and L. Pimenta (n = 8). The most frequent keywords, "complication" (n = 34), "surgery" (n = 30), and "outcomes" (n = 24), demonstrated a patient-centric theme. CONCLUSIONS: This bibliometric analysis provides in-depth insights into the evolution and trends of LIF over the last two decades. The trends and themes identified demonstrate the innovative, collaborative, and patient-focused characteristics of this subfield. Future researchers can use this as a foundation for understanding the past and present state of LIF research while designing investigations.

OBJECTIVE: Evaluate the independent effect of age on baseline neurocognitive performance. STUDY DESIGN: Baseline ImPACT scores from tests taken by 7454 athletes aged 12-22 from 2009 to 2019 were split into three age cohorts: 12-14 years (3244), 15-17 years (3732), and 18-22 years (477). Linear regression analyses were used to evaluate the effect of age on ImPACT composite scores while controlling for demographic differences, medication-use, and symptom burden. Significance values have been set at p < 0.05. RESULTS: Linear regression analyses demonstrated that increased age does not significantly affect symptom score (ß = 0.06, p = 0.54) but does improve impulse control (ß = -0.45, p < 0.0001), verbal memory (ß = 0.23, p = 0.03), visualmotor (ß = 0.77, p < 0.0001), and reaction time (ß = -0.008, p < 0.0001) scores. However, age did not have an effect on visual memory scores (ß = -0.25, p = 0.07). CONCLUSIONS: Age was shown to be an independent modifier of impulse control, verbal memory, visual motor, and reaction time scores but not visual memory or symptom scores. This underscores the previous literature showing developmental differences as age increases among the adolescent athlete population. This data also indicates the need for repeat neurocognitive baseline testing every other year as baseline scoring is likely to change as athletes become older.

OBJECTIVES: Intracerebral hemorrhages are associated with significant morbidity and mortality. While the ENRICH trial supports the efficacy of surgical evacuation for lobar hemorrhages, the impact of antithrombotic therapies on minimally invasive surgery outcomes remains unexplored. This study evaluates the effects of chronic anticoagulants and antiplatelets on the technical and longterm outcomes of minimally invasive intracerebral hemorrhage evacuation. MATERIALS AND METHODS: A prospectively collected registry of patients undergoing minimally invasive surgery for intracerebral hemorrhage from a single institution was analyzed (December 2015-September 2022). Data included key demographics, comorbidities, antithrombotic/reversal status, presenting clinical/radiographic characteristics, procedural metrics, and clinical outcomes. Patients were divided into control (neither therapy), antiplatelet-only, and anticoagulant-only groups, with antiplatelet/anticoagulant reversals conducted per current American Heart Association/American Stroke Association guidelines. Variables significant in univariate analyses (p<0.05) were advanced to multivariable regression models. RESULTS: Among 226 intracerebral hemorrhage patients treated with minimally invasive surgery, 41% (N=93) had antithrombotic medication history; 28% (N=64) received antiplatelets, and 9% (N=21) received anticoagulants. Patients on both therapies (N=6) were excluded. The antiplatelet group presented more frequently with lobar hemorrhages (56% vs. 37%; p=0.022), while patients on anticoagulants showed increased rates of intraventricular hemorrhage co-presentation (62% vs. 46%; p=0.011) compared to controls. Despite univariate analyses showing a higher postoperative hematoma volume (3.9 vs. 2.9 milliliters; p=0.020) and lower evacuation percentage (88% vs. 92%; p=0.019) for the antiplatelet group, and longer procedures for patients on anticoagulants (2.3 vs. 1.7 hours; p=0.042) compared to control, multivariable analyses indicated that antiplatelets and anticoagulants had no significant impact on these technical outcomes. Longitudinally, antithrombotics were not associated with increased rebleeding, less frequent discharge to home, lower 30-day mortality, or worse, 6-month Modified Rankin Scale scores. CONCLUSIONS: Patients on chronic antiplatelets and anticoagulants exhibited characteristic intracerebral hemorrhage phenotypes without worse technical or long-term outcomes after minimally invasive intracerebral hemorrhage evacuation, suggesting the procedure's safety for these patients.

BACKGROUND: Laparoscopic surgery is rapidly expanding in low-and middle-income countries (LMICs), yet many surgeons in LMICs have limited formal training in laparoscopy. In 2017, the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) implemented Global Laparoscopic Advancement Program (GLAP), an in-person simulation-based laparoscopic training curriculum for surgeons in LMICs. In light of COVID-19, SAGES adapted GLAP to a virtual format with telesimulation. This study explores the feasibility and efficacy of virtual laparoscopic simulation training in resource-limited settings. METHODS: Participants from San Jose, Costa Rica, Leon, México, and Guadalajara, México enrolled in the virtual GLAP curriculum, meeting biweekly for 2-h didactic classes and 2-h hands-on live simulation practice. Surgical residents' laparoscopic skills were evaluated using the five Fundamentals of Laparoscopic Surgery (FLS) tasks during the initial and final weeks of the program. Participants also completed pre-and post-program surveys assessing their perception of simulation-based training. RESULTS: The study cohort consisted of 16 surgical attendings and 20 general surgery residents. A minimum 70% response rate was recorded across all surveys in the study. By the end of GLAP, residents completed all five tasks of the FLS exam within less time relative to their performance at the beginning of the training program (p < 0.05). Respondents (100%) reported that the program was a good use of their time and that education via telesimulation was easily reproduced. Participants indicated that the practice sessions, guidance, and feedback offered by mentors were their favorite elements of the training. CONCLUSION: A virtual simulation-based curriculum can be an effective strategy for laparoscopic skills training. Participants demonstrated an improvement in laparoscopic skills, and they appreciated the mentorship and opportunity to practice laparoscopic skills. Future programs can expand on using a virtual platform as a low-cost, effective strategy for providing laparoscopic skills training to surgeons in LMICs.

BACKGROUND: The concept of a 'black cloud' is a common unfounded perception in the healthcare workforce that attributes a heavier workload to specific individuals or teams. Prior studies in non-surgical disciplines have demonstrated that 'black cloud' perceptions are not associated with workload, albeit such perceptions may influence behavior. The influence of 'black cloud' perceptions on surgical resident workload and burnout remains to be investigated. This study assesses the associations between 'black cloud' self-perception with actual workload and burnout among surgical residents in different specialties. METHODS: A cross-sectional survey study of postgraduate year (PGY) 2 and 3 residents enrolled in different surgical residencies at the Icahn School of Medicine at Mount Sinai was conducted between September-November 2021. RESULTS: The survey response rate was 62.1% (41/66). 46.3% of respondents were female. The majority of subjects were single (61%) and PGY2 trainees (56.1%). In a multivariate regression analysis demographic factors and workload variables, such as the number of pages responded, notes, and amount of sleep, were not significant predictors of a 'black cloud'-self-perception. A significantly lower Burnout Index Score (BIS) was observed among females (p< .001). A significantly higher BIS was observed among residents who are single (p = .003), training in general surgery (p = .02), and orthopedic surgery (p = .03). There was no significant association between 'black cloud' self-perception and BIS. DISCUSSION: The findings demonstrate that a 'black cloud' self-perception is not associated with a high workload and burnout among surgical residents. Gender, marriage/domestic partnership, and certain surgical specialties influenced burnout among the study cohort.

OBJECTIVE/ BACKGROUND: Chronic headaches and sports-related concussions are among the most common neurological morbidities in adolescents and young adults. Given that the two can overlap in presentation, studying the effects of one on another has proven difficult. In this longitudinal study, we sought to assess the relationship between chronic headaches and concussions, analyzing the role of historic concussions on chronic headaches, as well as that of premorbid headaches on future concussion incidence, severity, and recovery. METHODS: This multi-center, longitudinal cohort study followed 7,453 youth athletes who were administered demographic and clinical surveys as well as a total of 25,815 Immediate Post-concussion Assessment and Cognitive Testing (ImPACT) assessments between 2009 and 2019. ImPACT was administered at baseline. Throughout the season concussions were examined by physicians and athletic trainers, followed by re-administration of ImPACT post-injury (PI), and at follow-up (FU), a median of 7 days post-concussion. Concussion incidence was calculated as the total number of concussions per patient years. Concussion severity and recovery were calculated as standardized deviations from baseline to PI and then FU in Symptom Score and the four neurocognitive composite ImPACT scores: Verbal Memory, Visual Memory, Processing Speed, and Reaction Time. Data were collected prospectively in a well-organized electronic format supervised by a national research-oriented organization with rigorous quality assurance. Analysis was preformed retrospectively. RESULTS: Of the eligible athletes, 1,147 reported chronic headaches (CH) at the start of the season and 6,306 reported no such history (NH). Median age of the cohort was 15.4 ± 1.6 years, and students were followed for an average of 1.3 ± 0.6 years. A history of concussions (OR 2.31, P < 0.0001) was associated with CH. Specifically, a greater number of past concussions (r2 = 0.95) as well as concussions characterized by a loss of consciousness (P < 0.0001) were associated with more severe headache burden. The CH cohort had a greater future incidence of concussion than the NH cohort (55.6 vs. 43.0 per 100 patient-years, P < 0.0001). However, multivariate analysis controlling for demographic, clinical, academic, and sports-related variables yielded no such effect (OR 0.99, P = 0.85). On multivariable analysis the CH cohort did have greater deviations from baseline to PI and FU in Symptom Score (PI OR per point 1.05, P = 0.01, FU OR per point 1.11, P = 0.04) and Processing Speed (OR per point 1.08, P = 0.04), suggesting greater concussion severity and impaired symptomatic recovery as compared to the NH cohort. CONCLUSION: A history of concussions was a significant contributor to headache burden among American adolescents and young adults. However, those with chronic headaches were not more likely to be diagnosed with a concussion, despite presenting with more severe concussions that had protracted recovery. Our findings not only suggest the need for conservative management among youth athletes with chronic headaches, they also indicate a potential health care gap in this population, in that those with chronic headaches may be referred for concussion diagnosis and management at lower rates than those with no such comorbidity.

RESUMO
INTRODUCTION: War has influenced the evolution of global neurosurgery throughout the past century. Armed conflict and mass casualty disasters (MCDs), including Humanitarian Assistance Disaster Relief missions, require military surgeons to innovate to meet extreme demands. However, the military medical apparatus is seldom integrated into the civilian health care sector. Neurosurgeons serving in the military have provided a pragmatic template for global neurosurgeons to emulate in humanitarian disaster responses. In this paper, we explore how wars and MCD have influenced innovations of growing interest in the resource-limited settings of global neurosurgery. METHODS: We performed a narrative review of the literature examining the influence of wars and MCD on contemporary global neurosurgery practices. RESULTS: Wartime innovations that influenced global neurosurgery include the development of triage systems and modernization with airlifts, the implementation of ambulance corps, early operation on cranial injuries in hospital camps near the battlefield, the use of combat body armor, and the rise of damage control neurosurgery. In addition to promoting task-shifting and task-sharing, workforce shortages during wars and disasters contributed to the establishment of the physician assistant/physician associate profession in the USA. Low- and middle-income countries (LMICs) face similar challenges in developing trauma systems and obtaining advanced technology, including neurosurgical equipment like battery-powered computed tomography scanners. These challenges-ubiquitous in low-resource settings-have underpinned innovations in triage and wound care, rapid evacuation to tertiary care centers, and minimizing infection risk. CONCLUSION: War and MCDs have catalyzed significant advancements in neurosurgical care both in the pre-hospital and inpatient settings. Most of these innovations originated in the military and subsequently spread to the civilian sector as military neurosurgeons and reservist civilian neurosurgeons returned from the battlefront or other low-resource locations. Military neurosurgeons have utilized their experience in low-resource settings to make volunteer global neurosurgery efforts in LMICs successful. LMICs have, by necessity, responded to challenges arising from resource shortages by developing innovative, context-specific care paradigms and technologies.

OBJECTIVE: An adequate healthcare workforce characterizes high-quality health systems. Sustainable domestic neurosurgery training is critical to developing a local neurosurgical workforce in low- and middle-income countries (LMICs). This study evaluated how neurosurgical training is delivered in Ethiopia, provides a historical narrative of neurosurgery training in the nation, and proposes future educational opportunities. METHODS: A mixed-methods design consisting of a semi-structured interview and a comprehensive survey was used to acquire data. The interview participants included neurosurgery program directors and faculty involved in resident education. The survey was sent to all current neurosurgery residents in Ethiopia. RESULTS: Ethiopian neurosurgical service began in 1970, and neurosurgical education started in 2006 with the establishment of the Addis Ababa University (AAU) residency program. The survey response rate was 86%, with 69 of 80 eligible neurosurgery residents responding. Most respondents were male (93%), aged 20-25 years (62%), and enrolled in the AAU program (61%). The oldest medical schools affiliated with tertiary hospitals were the top feeder institutions for neurosurgery training. Seventy-one percent of respondents worked for more than 60 hours/week, and 52% logged at least 100 cases annually. Survey responses demonstrated a critical need to establish subspecialty training and harmonize the national training curriculum. CONCLUSIONS: The history of Ethiopian neurosurgery training exemplifies how global neurosurgery efforts focused on capacity building can rapidly expand the local neurosurgical workforces of LMICs. Opportunities for neurosurgical education require initiatives promoting a subspecialized, diverse workforce that attains both the clinical and academic proficiency necessary for advancing neurosurgical care locally and globally.

OBJECTIVE: Resection, chemotherapy, radiation therapy, and tumor treating fields significantly increase the overall survival (OS) of glioblastoma (GBM) patients. Yet, cost and healthcare disparities might limit access. Multiple studies have attributed more than 80% of the GBM disease burden to White patients. The aim of this study was to explore the intersections of race and social determinants of health (SDoH) with healthcare access and outcomes of GBM patients in a large metropolitan area. METHODS: In this retrospective single-center study, the tumor registry at the authors' institution (2011-2019) was queried to identify a GBM cohort according to the updated WHO criteria. Data were supplemented by electronic health records to include demographics, outcome, National Cancer Institute Comorbidity Index (NCI-CI), and the Agency for Healthcare Research and Quality (AHRQ) socioeconomic status (SES) index. RESULTS: A total of 276 unique patients met the study inclusion criteria; 46% of the cohort was female, and 45% was non-White. This racial proportion differs from previous reports indicating that 80% of patients with GBM are White. The proportion of non-White patients in this study was similar to that of the general US population and significantly lower than that of New York City (p < 0.05). Non-White patients predominantly composed the lowest AHRQ SES index quartile, while White patients constituted the highest quartile (p < 0.001). White patients were older at diagnosis compared with non-White patients (63 vs 58 years, p = 0.001). Older age (p = 0.03), higher NCI-CI (p = 0.0006), and lack of insurance (p = 0.03) reduced the odds of a home discharge. Private insurance (p = 0.005), younger age (p = 0.02), and the highest ("wealthiest") AHRQ SES index quartile (p = 0.02) predicted a lower hospital length of stay (LOS). Patients who underwent gross-total resection had greater OS than those who received a subtotal resection or biopsy, independent of race and SDoH (1.68 vs 1.4 years, p = 0.022). CONCLUSIONS: This study is the first to report on race and SDoH of a cohort using the latest WHO criteria for GBM classification. In contrast to previous literature, the study cohort exhibits a higher proportion of non-White patients with GBM, similar to the representation of non-White individuals in the general US population. This study corroborates the impact of SDoH and not race on LOS and discharge location. Initiatives to identify and address these barriers are crucial for enhancing the care of all GBM patients.

OBJECTIVE: The objective of this study was to investigate the perioperative management and outcomes of patients with a prior history of successful transplantation undergoing spine surgery. METHODS: We searched Medline, Embase, and Cochrane Central Register of Controlled Trials for matching reports in July 2021. We included case reports, cohort studies, and retrospective analyses, including terms for various transplant types and an exhaustive list of key words for various forms of spine surgery. RESULTS: We included 45 studies consisting of 34 case reports (published 1982-2021), 3 cohort analyses (published 2005-2006), and 8 retrospective analyses (published 2006-2020). The total number of patients included in the case reports, cohort studies, and retrospective analysis was 35, 48, and 9695, respectively. The mean 1-year mortality rate from retrospective analyses was 4.6% ± 1.93%, while the prevalence of perioperative complications was 24%. Cohort studies demonstrated an 8.5% ± 12.03% 30-day readmission rate. The most common procedure performed was laminectomy (38.9%) among the case reports. Mortality after spine surgery was noted for 4 of 35 case report patients (11.4%). CONCLUSIONS: This is the first systematic scoping review examining the population of transplant patients with subsequent unrelated spine surgery. There is significant heterogeneity in the outcomes of post-transplant spine surgery patients. Given the inherent complexity of managing this group and elevated mortality and complications compared to the general spine surgery population, further investigation into their clinical care is warranted.

The burden of trauma-related mortality is inversely related to income on an individual and national scale. Barthélemy et al highlight the significant variation of neurotrauma data included in national injury registries of low- and middle-income countries (LMICs) when compared to the World Health Organization (WHO) minimal dataset for injury (MDI). Moreover, the authors emphasize that the non-existence and underutilization of nationally standardized trauma registries hinder the data-driven identification of factors contributing to neurotrauma and subsequent attempts to improve neurotrauma care. Establishing a nationally standardized trauma registry should be prioritized by all stakeholders involved in curbing trauma-related mortality and building research capacity in LMICs. In this commentary, previous successful efforts to establish and maintain robust registries in LMICs through local and international partnerships are highlighted. The lessons and challenges chronicled in establishing such registries can inform future efforts to implement a nationally standardized trauma registry.

Ultimately, the study's findings provide valuable guidance for future research and contribute to advancing our understanding of this critical area of study.
RESUMO
BACKGROUND: Improving and fostering diversity within the neurosurgical workforce has become a high priority. This cross-sectional study aims to provide data on the diversity of neurosurgical oncology faculty (NSOF) in the US. METHODS: All 115 neurosurgery (NS) Accreditation Council for Graduate Medical Education (ACGME) accredited programs were included in this study. The academic rank, academic and clinical title(s), gender, race, and hiring date of neurosurgical faculty with a primary focus on neurosurgical oncology (NSOF) were recorded. Geographical distribution and "top 10" programs were tabulated according to published data. Underrepresented minorities in medicine (URiM) faculty were identified according to the AAMC definition. RESULTS: The NSOF workforce constitutes 21% of the total NS faculty. Of these, 10.1% are women and 9.9% are URiM (P < .001). Currently, 58% of neurosurgery programs (NSP) do not have URiM and/or women NSOF. The top 10 ranked NSP, according to Blue Ridge Institute for Medical Research, had a significantly less URiM NSOF (P = .019) than nontop 10 ranked programs. There was a decreasing trend in the proportion of URiM at higher academic ranks (P = .019). All of the URiM department chairs (3/113)-all men-and 1/3 women department chairs nationwide subspecialized in neurosurgical oncology. CONCLUSIONS: Neurosurgical oncology is a sought-after subspecialty attracting a fifth of neurosurgeons practicing in ACGME-accredited training programs. Changing demographics and the benefits of workforce diversity represent a great opportunity for our field to continue leading inclusion efforts and attracting the best and brightest.

BACKGROUND: Neurosurgery is a rapidly developing specialty in Ethiopia. Previous global neurosurgery studies have highlighted the need for synchronizing workforce increase with improving quality, access, and capacity to provide neurosurgical care. OBJECTIVE: To evaluate Ethiopia's neurosurgical system and highlight the critical interventions required for the sustained development of Ethiopian neurosurgery as part of a high-quality health system (HQHS). METHODS: A comprehensive survey was sent to all practicing neurosurgeons. Public databases on Ethiopian census reports and current road infrastructure were used for spatial analysis of neurosurgical access. RESULTS: The survey response rate was 90% (45/50). Most respondents were men (95.6%), aged 30 to 40 years (82%), who worked at national referral hospitals (71%). The reported annual caseload per practicing neurosurgeon was >150 cases for 40% of urban and 20% of rural neurosurgeons. Head and spine neurotrauma and tumors were the most common neurosurgical indications. Computed tomography scanner was the most widely available diagnostic equipment (62%). 76% of respondents indicated the presence of postoperative rehabilitation care at their institutions. Thirteen percent and 27% of the nation lived within a 2-hour and 4-hour driving distance from a neurosurgical center, respectively. CONCLUSION: The results highlight the need for vital improvements in neurosurgical capacity to sustain progress toward HQHS. Promoting sustained development in all components of HQHS can be achieved by diversifying the workforce and training residency candidates committed to practicing in underserved regions. Additional strategies might include establishing a national registry for neurosurgical data and implementing policy changes conducive to improving perihospital care and other health system components.

OBJECTIVE: In 2015, the Association of American Medical Colleges report titled "Altering the Course: Black Males in Medicine" showed a decline in the number of Black men matriculating into medical school. To alter this trend, the authors' hypothesis was that formally exposing Black men to the clinical neurosciences during high school would enhance their chances of entering the physician workforce. For this reason, in 2007, the Doctors Reaching Minority Men Exploring Neuroscience (DR. MMEN) program was established at the Icahn School of Medicine at Mount Sinai. The program aimed to provide early exposure, mentorship, and inspiration to high school-age Black and Latinx men. The aim of this study was to evaluate the impact of the DR. MMEN program in the context of the recent race and ethnicity trends among medical school matriculants (MSMs). METHODS: Association of American Medical Colleges data on MSMs stratified by race and ethnicity were reviewed for the period between 2015 and 2020. Data pertinent to the academic achievements of DR. MMEN participants, such as matriculation to college and/or medical school, were prospectively tracked and incorporated with mixed-methods exit assessment data. Qualitative responses were coded and analyzed using a thematic concept analysis method. RESULTS: Over the study period, the increase of MSMs in the US was 1.0% and 1.7% for Black and Latinx individuals, respectively. Changes for the male MSM cohort were negligible: 0.3% for Black and 0.7% for Latinx. With respect to DR. MMEN, 42% of participants from 2017 to 2019 earned college scholarships, and 25% of students from the 2017-2018 cohort matriculated to a combined college-medical program. Survey data showed that 100% of DR. MMEN participants found the program useful. Analysis of qualitative data revealed that participants considered pursuing a career in neurosurgery or in another medical field. Diligence and a passion for medicine were identified as the top two most important lessons in the program, and witnessing patient satisfaction and observing a neurosurgery operation were described as the most important experiences. Participants considered availability to give advice and feedback and a passion for teaching as the principal attributes of their mentors. CONCLUSIONS: Over the past 6 years, the slight increase in Black and Latinx MSMs has not been significant enough to remedy ethnoracial disparities among MSMs. In particular, Black male matriculation to medical school has remained stagnant. The DR. MMEN program is a promising model to inspire young scholars and improve diversity within neuroscience and medicine at large.

BACKGROUND: International medical graduates (IMGs) comprise â¼25% of physicians in the United States. Differences in promotion rates from assistant to associate to full professorship based on medical school location have been understudied. We aim to stratify odds of professional advancement by 3 categories: IMG with U.S. residency, IMG with international residency, and U.S. medical with U.S. residency training. METHODS: We created and queried a database after exclusions of 1334 neurosurgeons including multiple demographic factors: academic productivity and promotion rates. Stratified logistic regression modeled odds of promotion including the variables: decades out of training, Scopus h-index, gender, and training location. Odds ratios (ORs) and 95% confidence intervals (CIs) for each variable were calculated. RESULTS: Significant predictors of increased associate versus assistant professorship included decades out of training (OR = 2.519 [95% CI: 2.07-3.093], P < 0.0001) and Scopus h-index (OR = 1.085 [95% CI: 1.064-1.108], P < 0.0001) while international medical school with U.S. residency (OR = 0.471 [95% CI: 0.231-0.914], P = 0.0352) was associated with decreased promotion. Significant predictors of associate versus full professorship were decades out of training (OR = 2.781 [95% CI: 2.268-3.444], P < 0.0001) and Scopus h-index (OR = 1.064 [95% CI: 1.049-1.080], P < 0.0001). Attending medical school or residency internationally was not associated with odds of full professorship. CONCLUSIONS: Time out of residency and Scopus h-index were associated with higher academic rank regardless of career level. Attending medical school internationally with U.S. residency was associated with lower odds of associate professorship promotion over 10 years. There was no relationship between IMG and full professorship promotion. IMGs who attended residency internationally did not have lower promotion rates. These findings suggest it may be harder for IMGs to earn promotion from assistant to associate professor in neurosurgery.
RESUMO
OBJECTIVE: Bibliometrics assessing academic productivity plays a significant role in neurosurgeons' career advancement. This study aimed to evaluate the influence of multiple author profiles on Scopus on neurosurgeon author-level metrics (h-index, document number, citation number). METHODS: A list of 1671 academic neurosurgeons was compiled through public searches of hospital and faculty websites for 115 neurosurgical residency training programs. The h-index, document number, and citation number for each neurosurgeon were collected using the Scopus algorithm. For surgeons with multiple profiles, total document number and citation number were calculated by summing results of each profile. Cumulative h-indices were calculated manually. Comparisons were made between surgeons with a single Scopus profile and surgeons with multiple profiles. RESULTS: A total of 124 neurosurgeons with multiple profiles were identified. Gender distribution (P = 0.47), years in practice (P = 0.06), subspecialty (P = 0.32), and academic rank (P = 0.16) between neurosurgeons with a single profile versus multiple profiles were similar. Primary profile h-index median was 16 (interquartile range [IQR]: 8-34), combined profiles median was 20 (IQR: 11-36), and percent loss median was 17.3% (IQR: 3%-33%) (P < 0.001). For document number, primary profile median was 46 (IQR: 16-127), combined profiles median was 55 (IQR: 22-148), and percent loss median was 16.2% (IQR: 7%-36%) (P < 0.001). For citation number, primary profile median was 1030 (IQR: 333-4082), combined profiles median was 1319 (IQR: 546-4439), and percent loss median was 14.1% (IQR: 4%-32%) (P < 0.001). CONCLUSIONS: U.S. academic neurosurgeons with multiple existing profiles on Scopus experience a 17.3% loss in h-index, a 16.2% loss in document number, and a 14.1% loss in citations, heavily undercounting their perceived academic productivity.
