BACKGROUND AND OBJECTIVES: Neural tube defects (NTDs) are an important cause of global morbidity worldwide. Well-planned global neurosurgery and public health efforts can aid vulnerable communities, but there is a need to elucidate the global burden of NTDs and identify regions without available data to better target interventions. METHODS: A scoping review to quantify worldwide NTD prevalence using the PubMed/Medline and birth defects surveillance registries was conducted. Data published after January 1, 1990, encompassing prevalence values of at least the 2 most prevalent NTDs-spina bifida and encephalocele-were abstracted. Average NTD prevalence rates were aggregated by World Health Organization (WHO) region and World Bank classification, and differences were determined using the analysis of variance test. Differences in availability of nationally representative data by WHO region and World Bank classification were determined using χ2 tests. RESULTS: This review captured 140 studies from a total of 93 of 194 WHO member countries. The percentage of countries within a geographic region with available NTD prevalence data was highest in the Eastern Mediterranean (EMR) (85.7%) and lowest in Africa (AFR) (31.3%). The NTD prevalence range was 0.9-269.6 per 10 000 births. Statistically significant differences in reported NTD prevalence rates existed by WHO Region (P = .00027) and World Bank income level of study country (P = .00193). Forty countries (43%) had conducted national-level studies assessing NTD prevalence. There was a statistically significant difference in the availability of nationally representative prevalence data depending on the WHO region (P = .0081) and World Bank classification of study country (P = .0017). CONCLUSION: There is a gap in availability of NTD prevalence data worldwide, with many WHO member states lacking national-level NTD prevalence estimates. These findings highlight the need for greater NTD surveillance efforts to identify the countries with the greatest need for targeted global intervention.
RESUMEN
OBJECTIVE: Global neurosurgery is a public health focus in neurosurgery that seeks to ensure safe, timely, and affordable neurosurgical care to all individuals worldwide. Although investigators have begun to explore the promise of artificial intelligence (AI) for neurosurgery, its applicability to global neurosurgery has been largely hypothetical. We characterize opportunities and considerations for the incorporation of AI into global neurosurgery by synthesizing key themes yielded from a series of generative pretrained transformers (GPTs), discuss important limitations of GPTs and cautions when using AI in neurosurgery, and develop a framework for the equitable incorporation of AI into global neurosurgery. METHODS: ChatGPT, Bing Chat/Copilot, You, Perplexity.ai, and Google Bard were queried with the prompt "How can AI be incorporated into global neurosurgery?" A layered ChatGPT-based thematic analysis was performed. The authors synthesized the results into opportunities and considerations for the incorporation of AI in global neurosurgery. A Pareto analysis was conducted to determine common themes. RESULTS: Eight opportunities and 14 important considerations were synthesized. Six opportunities related to patient care, 1 to education, and another to public health planning. Four of the important considerations were deemed specific to global neurosurgery. The Pareto analysis included all 8 opportunities and 5 considerations. CONCLUSIONS: AI may be incorporated into global neurosurgery in a variety of capacities requiring numerous considerations. The framework presented in this manuscript may facilitate the incorporation of AI into global neurosurgery initiatives while balancing contextual factors and the reality of limited resources.

Since the first African country attained independence from colonial rule, surgical training on the continent has evolved along 3 principal models. The first is a colonial, local master-apprentice model, the second is a purely local training model, and the third is a collegiate intercountry model. The 3 models exist currently and there are varied perceptions of their relative merits in training competent neurosurgeons. We reviewed the historical development of training and in an accompanying study, seek to describe the complex array of surgical training pathways and explore the neocolonial underpinnings of how these various models of training impact today the development of surgical capacity in Africa. In addition, we sought to better understand how some training systems may contribute to the widely recognized "brain drain" of surgeons from the African continent to high income countries in Europe and North America. To date, there are no published studies evaluating the impact of surgical training systems on skilled workforce emigration out of Africa. This review aims to discover potentially addressable sources of improving healthcare and training equity in this region.

BACKGROUND: Neurosurgery, an intricate and dynamic surgical specialty, faces challenges in attracting medical graduates. Despite its potential appeal, a decreasing trend in medical students opting for surgical specialties, including neurosurgery, is noted. This study aims to assess European medical students' perceptions of neurosurgery, focusing on South-East Europe, and address concerns about the declining interest in this field. METHODS: A comprehensive digital survey, comprising 33 questions, was distributed to 1115 medical students across 17 European countries. The survey, conducted over 9 months, gathered responses through European neurosurgical societies, the European Association of Neurosurgical Societies (EANS), and university channels. Statistical analysis utilized IBM Statistical Package for the Social Sciences, presenting data through counts, proportions, and χ2 tests. RESULTS: The study reveals that, over the survey period, 834 medical students completed the questionnaire, with a predominant representation from South-East Europe. While 43.2% of participants were considering a surgical career, neurosurgery emerged as the most preferred specialty (26.37%). Despite this interest, 80.2% reported insufficient knowledge about pursuing a neurosurgical career, with limited exposure during medical education. Concerns about work-life balance, heavy workload, and hierarchical structures were prominent among respondents. CONCLUSIONS: The findings underscore the need for targeted interventions to address concerns influencing medical students' decisions regarding neurosurgery. Improving neurosurgical education, dispelling misconceptions, and creating a supportive work environment are crucial steps to attract and retain diverse talented individuals in neurosurgery. These efforts will be vital in narrowing the gap between the demand for neurosurgeons and the number of medical graduates entering the field, ensuring a sustainable future for this essential surgical specialty.

Since 2018, a neurosurgery delegation has been actively engaged and consistently present at the World Health Assembly. Recognizing the growing impact of neurosurgical diseases, the neurosurgery delegation participated in the 76th World Health Assembly in May 2023, advocating for timely, safe, and affordable global neurosurgical care. The delegation focused on forging new collaborations, strengthening the World Health Organization-World Federation of Neurosurgical Societies official relations, and actively supporting resolutions that impact the neurosurgical patients. However, there is a long advocacy journey ahead to address unmet neurosurgical needs. Patient-centered advocacy is an inherent task of our profession and the essence of the Global Neurosurgery Bogota Declaration of 2016. The highlight of the 76th World Health Assembly was the adoption of the first neurosurgery-driven resolution calling for micronutrient fortification to prevent spina bifida and other micronutrient deficiencies. For the last 4 years, the Global Alliance for Prevention of Spina Bifida, a group spearheaded by neurosurgeons, advocated for spina bifida prevention. This Alliance collaborated with many stakeholders, notably, the Colombian government to promote the resolution: "Accelerating efforts for preventing micronutrient deficiencies and their consequences, including spina bifida and other neural tube defects, through safe and effective food fortification." This is a proud milestone for the neurosurgical profession. There are many strategies available for neurosurgeons, when working together with elected leaders, other stakeholders, and allied professionals, to implement initiatives that can prevent future cases of spina bifida and other neurological disorders and reduce the burden of neurosurgical disease.

OBJECTIVE: The structure and specifics of neurosurgery residency training vary substantially across programs and countries, potentially leading to differences in clinical reasoning, surgical skills, and professionalism. The Greek neurosurgical training system is unique in numerous respects. This manuscript delineates the current state of neurosurgical residency training in Greece and outlines future directions. METHODS: A narrative review was conducted to describe the Greek neurosurgical residency training structure. The perspectives of the authors regarding challenges in training and future directions were synthesized. RESULTS: This manuscript describes the neurosurgery residency curriculum and board certification process, existing training programs, and key challenges in neurosurgery residency training in Greece. The authors propose future directions to reform neurosurgical training in Greece. CONCLUSIONS: Neurosurgery residency training in Greece has been largely unchanged for many years. This review leads to suggested modification of the existing training process may improve the quality of training and equip neurosurgeons to respond to the rapidly changing landscape of the field.

BACKGROUND: As a result of gradual independence from colonial rule over the course of the past century, Africa has developed and evolved 3 primary surgical training structures: an extracontinental colonial model, an intracontinental college-based model, and several smaller national or local models. There is consistent evidence of international brain drain of surgical trainees and an unequal continental distribution of surgeons; however there has not, to date, been an evaluation of the impact colonialism on the evolution of surgical training on the continent. This study aims to identify the etiologies and consequences of this segmentation of surgical training in Africa. METHODS: This is a cross-sectional survey of the experience and perspectives of surgical training by current African trainees and graduates. RESULTS: A surgeon's region of residence was found to have a statistically significant positive association with that of a surgeon's training structure (P <0.001). A surgeon's professional college or structure of residency has a significantly positive association with desire to complete subspecialty training (P = 0.008). College and structure of residency also are statistically significantly associated with successful completion of subspecialty training (P < 0.001). CONCLUSIONS: These findings provide evidence to support the concept that the segmentation of surgical training structures in Africa, which is the direct result of prior colonization, has affected the distribution of trainees and specialists across the continent and the globe. This maldistribution of African surgical trainees directly impacts patient care, as the surgeon-patient ratios in many African countries are insufficient. These inequities should be acknowledged addressed and rectified to ensure that patients in Africa receive timely and appropriate surgical care.

BACKGROUND AND OBJECTIVES: Global disparity exists in the demographics, pathology, management, and outcomes of surgically treated traumatic brain injury (TBI). However, the factors underlying these differences, including intervention effectiveness, remain unclear. Establishing a more accurate global picture of the burden of TBI represents a challenging task requiring systematic and ongoing data collection of patients with TBI across all management modalities. The objective of this study was to establish a global registry that would enable local service benchmarking against a global standard, identification of unmet need in TBI management, and its evidence-based prioritization in policymaking. METHODS: The registry was developed in an iterative consensus-based manner by a panel of neurotrauma professionals. Proposed registry objectives, structure, and data points were established in 2 international multidisciplinary neurotrauma meetings, after which a survey consisting of the same data points was circulated within the global neurotrauma community. The survey results were disseminated in a final meeting to reach a consensus on the most pertinent registry variables. RESULTS: A total of 156 professionals from 53 countries, including both high-income countries and low- and middle-income countries, responded to the survey. The final consensus-based registry includes patients with TBI who required neurosurgical admission, a neurosurgical procedure, or a critical care admission. The data set comprised clinically pertinent information on demographics, injury characteristics, imaging, treatments, and short-term outcomes. Based on the consensus, the Global Epidemiology and Outcomes following Traumatic Brain Injury (GEO-TBI) registry was established. CONCLUSION: The GEO-TBI registry will enable high-quality data collection, clinical auditing, and research activity, and it is supported by the World Federation of Neurosurgical Societies and the National Institute of Health Research Global Health Program. The GEO-TBI registry ( https://geotbi.org ) is now open for participant site recruitment. Any center involved in TBI management is welcome to join the collaboration to access the registry.

Prior to the 1937 invention of the Raney clip, surgeons relied on hemostatic sutures, pneumatic tourniquets, sequentially applied hemostatic forceps, and the administration of local vasoconstrictive agents to achieve scalp hemostasis. The Raney clip is now the quintessential tool for achieving scalp hemostasis in cranial neurosurgery; with nearly 13.8 million cranial neurosurgical cases per year globally, Raney clips are in high demand and their use is ubiquitous. What is less known, however, is the story of their invention and the related stories of those who bear the Raney name. This paper fills these gaps in neurosurgical history, using information obtained during an extensive series of contemporary interviews and correspondence with the Raney family.

BACKGROUND AND OBJECTIVES: Traumatic spinal cord injuries (SCI), which disproportionally occur in low- and middle-income countries (LMICs), pose a significant global health challenge. Despite the prevalence and severity of SCI in these settings, access to appropriate surgical care and barriers to treatment remain poorly understood on a global scale, with data from LMICs being particularly scarce and underreported. This study sought to examine the impact of social determinants of health (SDoH) on the pooled in-hospital and follow-up mortality, and neurological outcomes, after SCI in LMICs. METHODS: A systematic review was conducted in adherence to the Preferred Reporting in Systematic Review and Meta-Analysis-guidelines. Multivariable analysis was performed by multivariable linear regression, investigating the impact of the parameters of interest (patient demographics, country SDoH characteristics) on major patient outcomes (in-hospital/follow-up mortality, neurological dysfunction). RESULTS: Forty-five (N = 45) studies were included for analysis, representing 13 individual countries and 18 134 total patients. The aggregate pooled in-hospital mortality rate was 6.46% and 17.29% at follow-up. The in-hospital severe neurological dysfunction rate was 97.64% and 57.36% at follow-up. Patients with rural injury had a nearly 4 times greater rate of severe in-hospital neurological deficits than patients in urban areas. The Gini index, reflective of income inequality, was associated with a 23.8% increase in in-hospital mortality, a 20.1% decrease in neurological dysfunction at follow-up, and a 12.9% increase in mortality at follow-up. CONCLUSION: This study demonstrates the prevalence of injury and impact of SDoH on major patient outcomes after SCI in LMICs. Future initiatives may use these findings to design global solutions for more equitable care of patients with SCI.
RESUMEN
Background: The epidemiology of traumatic brain injury (TBI) is unclear - it is estimated to affect 27-69 million individuals yearly with the bulk of the TBI burden in low-to-middle income countries (LMICs). Research has highlighted significant between-hospital variability in TBI outcomes following emergency surgery, but the overall incidence and epidemiology of TBI remains unclear. To address this need, we established the Global Epidemiology and Outcomes following Traumatic Brain Injury (GEO-TBI) registry, enabling recording of all TBI cases requiring admission irrespective of surgical treatment. Objective: The GEO-TBI: Incidence study aims to describe TBI epidemiology and outcomes according to development indices, and to highlight best practices to facilitate further comparative research. Design: Multi-centre, international, registry-based, prospective cohort study. Subjects: Any unit managing TBI and participating in the GEO-TBI registry will be eligible to join the study. Each unit will select a 90-day study period. All TBI patients meeting the registry inclusion criteria (neurosurgical/ICU admission or neurosurgical operation) during the selected study period will be included in the GEO-TBI: Incidence. Methods: All units will form a study team, that will gain local approval, identify eligible patients and input data. Data will be collected via the secure registry platform and validated after collection. Identifiers may be collected if required for local utility in accordance with the GEO-TBI protocol. Data: Data related to initial presentation, interventions and short-term outcomes will be collected in line with the GEO-TBI core dataset, developed following consensus from an iterative survey and feedback process. Patient demographics, injury details, timing and nature of interventions and post-injury care will be collected alongside associated complications. The primary outcome measures for the study will be the Glasgow Outcome at Discharge Scale (GODS) and 14-day mortality. Secondary outcome measures will be mortality and extended Glasgow Outcome Scale (GOSE) at the most recent follow-up timepoint.
Traumatic brain injury (TBI) is a significant global health problem, which affects 2769 million people every year. After-effects of TBI commonly affect the injured individuals for years. Most patients who sustain a TBI are from developing countries. Research has shown that there are differences in patients' recovery after TBI between countries and hospitals. The causes of these differences are unclear and tackling them could improve TBI treatment worldwide. To address this need, we have recently established the Global Epidemiology and Outcomes Following Traumatic Brain Injury (GEO-TBI) registry. The international collaborative registry aims to collect data related to the causes, treatments and outcomes related to TBI patients. This data will hopefully enable future research to elucidate the causes of the recovery differences between hospitals, which could lead to improved patient outcomes. The GEO-TBI: Incidence study collects data from all TBI patients that are admitted to participating hospitals or undergo a neurosurgical operation due to TBI during a 90-day period. This study looks at the patient's recovery at discharge using the Glasgow Outcome at Discharge Scale (GODS), and at the 2-week mortality. In addition, the study also evaluates recovery at the most recent follow-up timepoint. We hope that this information will enhance our understanding on the causes, treatments, and commonness of TBI. The study results will also help local hospitals compare their treatment results to an international standard.
RESUMEN
BACKGROUND: Cancer is a significant threat to public health and a leading cause of morbidity across the globe. Of all cancers, brain cancer can be particularly catastrophic as treatment often fails to achieve the desired degree of effectiveness and diagnosis remains associated with a high mortality rate. Africa, as a continent with resource-limited countries, needs to allocate the necessary proper healthcare infrastructure to significantly reduce cancer rates and improve patient survival. In addition, the relative paucity of data within this field in Africa makes effective management a challenge. OBJECTIVE: This review is aimed at elucidating the currently available evidence base with regard to the epidemiology and etiology of brain cancer within resource-limited African countries. This review hopes to bring to the attention of the wider clinical community the growing burden of brain cancer within Africa and to encourage future research into this field of research. METHODS: The available literature for this Systematic Review was searched on two bibliographic databases, PubMed and Scopus, using an individually verified, prespecified approach. In addition, the Global Cancer Observatory and Global Burden of Disease databases were also utilized. Studies reporting on the epidemiology, etiology, and impact of brain cancer in Africa were suitable for inclusion. The level of evidence of the included studies was considered as per the Centre for Evidence-Based Medicine recommendations. RESULTS: Out of the four databases searched, 3848 articles were initially screened rigorously, filtered into 54 articles, and finally assessed qualitatively and quantitatively. We have demonstrated a poor survival rate and lack of proper funds/resources necessary to report, identify, and treat cases, as well as the dearth of comprehensive research on the subject of brain cancer that has become a challenging healthcare concern in many African developing nations. Also, because of the gradual improvement in healthcare facilities and the increasing population within many countries in Africa, the number of patients with central nervous system and intracranial tumors is rising specifically in the elder population. In addition, the population in West Africa is at a higher risk of HIV-related malignancies due to the high prevalence of HIV in West Africa. The burden of brain cancer in Africa is increasing in comparison with the developed parts of the world in which it is decreasing. Moreover, the mismanagement of cancers in Africa leads to higher morbidity and mortality and decreased quality of life. CONCLUSION: This study addresses the burden of brain cancer as a major public health crisis in Africa. Improved treatment modalities and access to screening are required to better address the burden of this disease. Therefore, there is a clear need for more substantial and comprehensive research on etiology, epidemiology, and treatment of brain cancer within Africa to understand its epidemiological distribution and provide a means for managing and reducing the associated morbidity and mortality.

OBJECTIVE: Most surgical journals are published in English, representing a challenge for researchers from non-Anglophone countries. We describe the implementation, workflow, outcomes, and lessons learned from the WORLD NEUROSURGERY Global Champions Program (GCP), a novel journal-specific English language editing program for articles rejected because of poor English grammar or usage. METHODS: The GCP was advertised via the journal website and social media. Applicants were selected to be a reviewer for the GCP if they demonstrated English proficiency on writing samples supplied in their application. The demographics of GCP members and characteristics and outcomes of articles edited by the GCP during its first year were reviewed. Surveys of GCP members and authors who used the service were conducted. RESULTS: Twenty-one individuals became part of the GCP, representing 8 countries and 16 languages apart from English. A total of 380 manuscripts were peer reviewed by the editor-in-chief, who determined these manuscripts to have potentially worthwhile content but needed to be rejected due to poor language. The authors of these manuscripts were informed of the existence of this language assistance program. Forty-nine articles (12.9%) were edited by the GCP in 41.6 ± 22.8 days. Of 40 articles resubmitted to WORLD NEUROSURGERY, 24 (60.0%) were accepted. GCP members and authors understood the purpose and workflow of the program and recognized improvements in article quality and the probability of acceptance through their participation. CONCLUSIONS: The WORLD NEUROSURGERY Global Champions Program mitigated a critical barrier to publication in an English language journal for authors from non-Anglophone countries. This program promotes research equity by providing a free, largely medical student and trainee operated, English language editing service. This model or a similar service can be replicated by other journals.
RESUMEN
BACKGROUND: Neural tube defects continue to be one of the main congenital malformations affecting the development of the nervous system and a significant cause of disability and disease burden to individuals living with these conditions. Mandatory food fortification with folic acid is, by far, one of the most efficacious, safe, and cost-effective interventions to prevent neural tube defects. However, most countries fail to effectively fortify staple foods with folic acid, impacting public health and healthcare systems and generating dismal disparities. AIM: This article discusses the main barriers and facilitators for implementing mandatory food fortification as an evidence-based policy to prevent neural tube defects worldwide. METHODS: A comprehensive review of the scientific literature allowed the identification of the determinant factors acting as barriers or facilitators for the reach, adoption, implementation, and scaling up of mandatory food fortification with folic acid as an evidence-based policy. RESULTS: We identified eight barriers and seven facilitators as determinant factors for food fortification policies. The identified factors were classified as individual, contextual, and external, inspired by the Consolidated Framework for Implementation of Research (CFIR). We discuss mechanisms to overcome obstacles and seize the opportunities to approach this public health intervention safely and effectively. CONCLUSIONS: Several determinant factors acting as barriers or facilitators influence the implementation of mandatory food fortification as an evidence-based policy worldwide. Notoriously, policymakers in many countries may lack knowledge of the benefits of scaling up their policies to prevent folic acid-sensitive neural tube defects, improve the health status of their communities, and promote the protection of many children from these disabling but preventable conditions. Not addressing this problem negatively affects four levels: public health, society, family, and individuals. Science-driven advocacy and partnerships with essential stakeholders can help overcome the barriers and leverage the facilitators for safe and effective food fortification.

Neurosurgical advocates for global surgery/neurosurgery at the 75th World Health Assembly gathered in person for the first time after the COVID-19 pandemic in Geneva, Switzerland, in May 2022. This article reviews the significant progress in the global health landscape targeting neglected neurosurgical patients, emphasizing high-level policy advocacy and international efforts to support a new World Health Assembly resolution in mandatory folic acid fortification to prevent neural tube defects. The process of developing global resolutions through the World Health Organization and its member states is summarized. Two new global initiatives focused on the surgical patients among the most vulnerable member states are discussed, the Global Surgery Foundation and the Global Action Plan on Epilepsy and other Neurological Disorders. Progress toward a neurosurgery-inspired resolution on mandatory folic acid fortification to prevent spina bifida-folate is described. In addition, priorities for moving the global health agenda forward for the neurosurgical patient as it relates to the global burden of neurological disease are reviewed after the COVID-19 pandemic.

BACKGROUND: Since the emergence of neurosurgery as a distinct specialty â¼100 years ago in Canada, it took >40 years for Canadian women to enter the field in the province of Quebec, and longer in the other provinces. METHODS: We provide a historical overview of Canadian women in neurosurgery, from the early pioneers to the modern-day leaders and innovators in the field. We also define the current participation of women in Canadian neurosurgery. Chain-referral sampling, historical books, interviews, personal communications, and online resources were used as data sources. RESULTS: Our historical review highlights the exceptional journey and unique experiences of female neurosurgeons, describes their achievements, and identifies career obstacles and enabling factors. We also incorporate comments from Canadian female neurosurgeons, both retired and in active practice, addressing gender inequities in the field, and provide advice and encouragement to the new generations to come. Despite the achievements of these female trailblazers, women represent a small proportion of the Canadian neurosurgery trainees and the active workforce, in stark contrast to the increasing number of women in medical school. CONCLUSIONS: To the best of our knowledge, this study represents the first historical overview of female women neurosurgeons in Canada. Providing a historical context will help us to better understand the important role of women in modern neurosurgery, identify persistent gender issues in the field, and provide a vision for aspiring female neurosurgeons.

BACKGROUND: This study assessed the international variation in surgical neuro-oncology practice and 30-day outcomes of patients who had surgery for an intracranial tumor during the COVID-19 pandemic. METHODS: We prospectively included adults aged ≥18 years who underwent surgery for a malignant or benign intracranial tumor across 55 international hospitals from 26 countries. Each participating hospital recorded cases for 3 consecutive months from the start of the pandemic. We categorized patients' location by World Bank income groups (high [HIC], upper-middle [UMIC], and low- and lower-middle [LLMIC]). Main outcomes were a change from routine management, SARS-CoV-2 infection, and 30-day mortality. We used a Bayesian multilevel logistic regression stratified by hospitals and adjusted for key confounders to estimate the association between income groups and mortality. RESULTS: Among 1016 patients, the number of patients in each income group was 765 (75.3%) in HIC, 142 (14.0%) in UMIC, and 109 (10.7%) in LLMIC. The management of 200 (19.8%) patients changed from usual care, most commonly delayed surgery. Within 30 days after surgery, 14 (1.4%) patients had a COVID-19 diagnosis and 39 (3.8%) patients died. In the multivariable model, LLMIC was associated with increased mortality (odds ratio 2.83, 95% credible interval 1.37-5.74) compared to HIC. CONCLUSIONS: The first wave of the pandemic had a significant impact on surgical decision-making. While the incidence of SARS-CoV-2 infection within 30 days after surgery was low, there was a disparity in mortality between countries and this warrants further examination to identify any modifiable factors.
