[PMID: 37939879 DOI: 10.1016/j.wneu.2023.11.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2023] [Revised: 10/31/2023] [Accepted: 11/01/2023] [Indexed: 11/10/2023]
Abstract
OBJECTIVE This study aims to provide a comprehensive overview of pediatric neurosurgery in Nigeria, since 1962, by assessing epidemiological data, management strategies, and case outcomes. METHODS A systematic bibliometric review of Nigerian neurosurgical literature was reported with the PRISMA guidelines. The Risk of Bias Assessment Tool was applied to all nonrandomized studies, and a descriptive analysis was performed for all variables. RESULTS We identified 12,295 pediatric patients from 196 published studies. Most publications (72.4%) occurred in the recent 2 decades, of which 40.3% were observational case reports/series. The patients were predominantly male (57.2%) and aged 0-18 years, with the majority (66.1%) belonging to the 0-5 age range. Most patients (63.4%) presented between 1-12 months. The most common presenting feature was altered consciousness (7.7%), with computed tomography (38.8%) being the most frequently utilized diagnostic imaging modality. The diagnoses with the greatest prevalence (60.2%) were congenital abnormalities such as hydrocephalus and neural tube defects. 57.5% of cases received surgical therapy, with ventriculoperitoneal shunt placement being the most noticeable procedure performed (36.4%). Complications were identified in 9.5% of cases, with a 4.5% death rate. The Glasgow Outcome Score (95.7%) was the primary outcome measure utilized, with positive outcomes reported in 59.3% of cases. CONCLUSIONS This review provides significant epidemiological data which emphasizes the country's enormous burden of pediatric neurosurgical cases. The findings can help guide clinical decisions as well as future research and policy development.

The Message of the Glasgow Coma Scale: A Comprehensive Bibliometric Analysis and Systematic Review of Clinical Practice Guidelines Spanning the Past 50 years. World Neurosurg 2024; 185:393-402.e27. [PMID: 38437980 DOI: 10.1016/j.wneu.2024.02.139] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2023] [Revised: 02/25/2024] [Accepted: 02/26/2024] [Indexed: 03/06/2024]
Abstract
BACKGROUND Despite the ubiquitous use of the Glasgow Coma Scale (GCS) worldwide, no study to date has objectively and quantitatively assessed its impact on the scientific literature and clinical practice. Therefore, we comprehensively analyzed scientific publications and clinical practice guidelines employing the GCS to gauge its clinical and academic impact, identify research hotspots, and inform future research on the topic. METHODS A cross-sectional bibliometric analysis was performed on Scopus to obtain relevant publications incorporating the GCS from 1974 to 2022. In addition, a systematic review of existing clinical practice guidelines in PubMed, Scopus, Web of Science, and Trip Database was performed. Validated bibliometric parameters including article title, journal, publication year, authors, citation count, country, institution, keywords, impact factor, and references were assessed. When evaluating clinical practice guidelines, the sponsoring organization, country of origin, specialty, and publication year were assessed. RESULTS A total of 37,633 articles originating from 3924 different scientific journals spanning 1974-2022 were included in the final analysis. The compound annual growth rate of publications referencing the GCS was 16.7%. Of 104 countries, the United States had the highest total number of publications employing the GCS (n = 8517). World Neurosurgery was the scientific periodical with the highest number of publications on the GCS (n = 798). The top trending author-supplied keyword was "traumatic brain injury" (n = 3408). The 97 included clinical practice guidelines most commonly employed the GCS in the fields of internal medicine (n = 22, 23%), critical care (n = 21, 22%), and neurotrauma (n = 19, 20%). CONCLUSIONS At the turn of the 50th anniversary of the GCS, we provided a unique and detailed description of the "path to success" of the GCS both in terms of its scientific and clinical impact. These results have not only a historical but also an important didactic value. Ultimately our detailed analysis, which revealed some of the factors that led the GCS to become such a widespread and highly influential score, may assist future researchers in their development of new outcome measures and clinical scores, especially as such tools become increasingly relevant in an evidence-based data-driven age.

Abstract
Outcomes from traumatic brain injury (TBI) including death differ significantly between high-, middle-, and low-income countries. Little is known, however, about differences in TBI research across the globe. The objective of this article was to examine randomized controlled trials (RCTs) of moderate-to-severe TBI in high-income countries (HICs) compared with low- and middle-income countries (LMICs), as defined by the World Bank income per capita cutoff of $13,205 US dollars. A systematic review was conducted for articles published in the English language to December 2022 inclusive using MEDLINE, PubMed, Scopus, CINAHL, EMBASE, and PsycINFO in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Inclusion criteria: (1) human participants with a mean age of ≥18 years; (2) ≥50% of the sample had moderate to severe TBI; and (3) the study design was a RCT. Data extracted included author, year, country, sample size, primary focus (medical/surgical management or rehabilitation), injury etiology, time post-injury, and indicator(s) used to define TBI severity. There were 662 RCTs (published 1978-2022) that met inclusion criteria comprising 91,946 participants. There were 48 countries represented: 30 HICs accounting for 451 RCTs (68.1%) and 18 LMICs accounting for 211 RCTs (31.9%). The 62.6% of RCTs from LMICs were conducted in the acute phase post-injury (≤1 month) compared with 42.1% of RCTs from HICs. Of RCTs from LMICs, 92.4% focused on medical/surgical management compared with 52.5% from HICs. Since 2016, more RCTs have been conducted in LMICs than in HICs, indicating the importance of better understanding this pattern of research output.

The Current Landscape of Neurosurgical Oncology in Low-Middle-Income Countries (LMIC): Strategies for the Path Forward. World Neurosurg 2024; 184:e291-e298. [PMID: 38286320 DOI: 10.1016/j.wneu.2024.01.118] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2023] [Revised: 01/20/2024] [Accepted: 01/22/2024] [Indexed: 01/31/2024]
Abstract
OBJECTIVE To promote global equity in research, innovation, and care, sharing knowledge and grasping current benchmarks is crucial. Despite LIC/LMIC constituting around 80% of the global population, their contribution to neurosurgery research is less than 5%. This study aims to assess the status of neurosurgical oncology in LIC/LMIC using published data, offering strategic insights for progress. METHODS Conducting a retrospective bibliometric analysis via PubMed and Scopus databases, we documented reports published (2015-2021) by neurosurgical department-affiliated investigators in LICs/LMICs. World Bank classifications identified LIC and LMIC. Reviewed papers underwent further scrutiny based on independent and associated keyword lists. RESULTS Our systematic approach revealed 189 studies from LMIC in 10 neurosurgery journals. Of these, 53% were case reports, with 88% focusing on brain pathologies and 12% on the spine. Intra-axial brain tumors (45.8%), extra-axial/skull base (38.4%), and metastasis (3.68%) were prominent. Among noncase report publications, surgical technique and outcome were common themes. India, Egypt, and Tunisia led in publications, with 94% appearing in journals with an impact factor below 5. No papers originated from LIC. CONCLUSIONS This study reinforces existing findings that data from LMIC inadequately represent their populations, impeding a comprehensive understanding of their neurosurgical oncology landscape. Language barriers and data collection difficulties contribute to this gap. Addressing these challenges could significantly enhance progress in shaping the future of neurosurgical oncology in these regions.

The availability, access, challenges and advancements in neurosurgical care in Africa: a mini review. Ann Med Surg (Lond) 2024; 86:2011-2015. [PMID: 38576995 PMCID: PMC10990298 DOI: 10.1097/ms9.0000000000001805] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2023] [Accepted: 01/29/2024] [Indexed: 04/06/2024] Open
Abstract
The availability and accessibility of neurosurgical care across Africa remains limited despite recent advancements. Overall, Africa accounts for 15% of the global neurosurgical disease burden but has access to less than 1% of neurosurgeons globally. While the number of neurosurgeons has increased in recent decades, huge workforce shortages remain, with the region facing the second-largest neurosurgical deficit. Access to adequate facilities and equipment is also lacking. Barriers like poverty, conflicts, and distance from care centres negatively impact patients' ability to access services. However, training programs like the World Federation of Neurosurgical Societies Rabat Training Center have contributed to building local capacity. Use of technologies like neuro-endoscopy is expanding access to more cost-effective interventions for conditions such as hydrocephalus. Undergraduate medical education is also seeing a rise in African students interested in neurosurgery. Despite these advancements, workforce shortfalls, inadequate infrastructure, and challenges posed by geopolitical instability continue to hinder the provision of comprehensive neurosurgical care. Limited research and funding discourage experienced surgeons from practicing in their home countries. Increased international collaboration, support for education, and tackling of structural issues are needed to continue strengthening Africa's neurosurgical capacity and reducing the disease burden. This narrative review aims to provide an overview of the current state of neurosurgery on the continent, highlight achievements, and identify persisting challenges.

Chinese Neurosurgical Randomized Controlled Trials: Dynamics in Trial Implementation and Completion. Neurosurgery 2024; 94:497-507. [PMID: 37796000 DOI: 10.1227/neu.0000000000002702] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2023] [Accepted: 08/03/2023] [Indexed: 10/06/2023] Open
Abstract
BACKGROUND AND OBJECTIVES The focus on evidence-based neurosurgery has led to a considerable amount of neurosurgical evidence based on randomized controlled trials (RCTs) being published. Nevertheless, there has been no systematic appraisal of China's contribution to RCTs. Information about the changes in characteristics of Chinese neurosurgical RCTs before and during the COVID-19 pandemic is limited. This study aims to perform a detailed examination and comprehensive analysis of the characteristics of Chinese neurosurgical RCTs and to examine the differences before and during the COVID-19 pandemic. METHODS We conducted a comprehensive database search including PubMed, Web of Science, Embase, and Cochrane Library up to March 2023, with a criterion of inclusion based on an impact factor above 0. We subsequently examined the design and quality parameters of the included RCTs and assessed the differences before and during the COVID-19 pandemic (based on follow-up ending before or after January 2020). Moreover, we investigated potential factors that may affect the quality and developmental trends of neurosurgical RCTs in China. RESULTS The main focus of the 91 neurosurgical RCTs was vascular disease (47.3%) and trauma (18.7%). Over half of the trials used Consolidated Standards of Reporting Trial diagrams (69.2%), and the majority compared nonsurgical treatments (63.7%). Larger trials tended to have better quality scores, but those with significant efficacy were less likely to have power calculations. Over time, there was an increase in the use of Consolidated Standards of Reporting Trial diagrams and well-specified outcomes. The COVID-19 pandemic may have hindered the completion of neurosurgical RCTs in China, but it has had little impact on the design and quality so far. CONCLUSION Chinese neurosurgeons have made significant progress in advancing neurosurgical RCTs despite challenges. However, shortcomings in sample size and power calculation need attention. Improving the rigor, rationality, and completeness of neurosurgical RCT design is crucial.

A Mixed-Methods Assessment of the Feasibility of Conducting Neurosurgical Clinical Research in Uganda. World Neurosurg 2024; 183:e71-e87. [PMID: 38006934 DOI: 10.1016/j.wneu.2023.11.079] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2023] [Accepted: 11/16/2023] [Indexed: 11/27/2023]
Abstract
BACKGROUND Clinical research is necessary to evaluate neurosurgical interventions, yet clinical trials are conducted less frequently in low- and middle-income countries. Because specific barriers, facilitating factors, and strategies for neurosurgical clinical research in Uganda have not been previously identified, this study evaluated neurosurgical providers' perspectives on clinical research and documentation patterns of neurosurgical variables at Mulago National Referral Hospital. METHODS Retrospective review of 166 neurosurgical patient charts assessed the frequency of documentation of key variables. Twenty-two providers working in neurosurgery participated in 6 focus group discussions with qualitative analysis utilizing the framework method. RESULTS Chart review showed that primary diagnosis (99.4%), pupil light response (97.6%), and computed tomography scan results (93.3%) were documented for most patients. Cranial nerve exam (61.5%), pupil size (69.9%), and time to neurosurgical intervention (45%) were documented less frequently. On average, Glasgow Coma Scale was documented for 86.6% of days hospitalized, while vital signs were documented for 12.3%. In most focus group discussions, participants identified follow-up, financing, recruitment, time, approval, and sociocultural factors as research barriers. Participants described how the current health workforce facilitates successful research. To improve research capacity, suggested strategies focused on research networks, data collection, leadership, participant recruitment, infrastructure, and implementation. CONCLUSIONS At Mulago National Referral Hospital, there was variability in the frequency of documentation of neurosurgical variables, which may impact data collection for future studies. While multiple barriers were identified, sociocultural, financing, and time barriers greatly impacted neurosurgical clinical research. Despite that, identified facilitating factors and strategies could be utilized to support neurosurgical research capacity growth.

Abstract
Traumatic brain injury (TBI) is a leading cause of death and disability worldwide. Disparities exist in the populations that acquire TBIs, however, with a greater burden and poorer outcomes associated with communities of color and lower socioeconomic status. To combat health inequities such as these, institutions have begun to target social determinants of health (SDoH), which are environmental factors that affect health outcomes and risks. The SDoH may play a role in sustaining a TBI and provide modifiable targets for action to reduce the risk of TBI, especially in high-risk communities. In this study, we describe the existing literature regarding SDoH and their association with sustaining a TBI. We performed a scoping review with a comprehensive search of the Ovid MEDLINE/Embase databases. To summarize the literature, this review adapts the World Health Organization's Commission on SDoH's conceptual framework. Fifty-nine full-text articles, including five focusing on lower and middle-income countries, met our study criteria. Results of the scoping review indicate that several structural determinants of health were associated with TBI risk. Lower educational attainment and income levels were associated with higher odds of TBI. In addition, multiple studies highlight that minority populations were identified as having higher odds of TBI than their White counterparts. Literature highlighting intermediate determinants of health examined in this review describes associations between sustaining a TBI and rurality, work environment, medical conditions, medication/substance use, and adversity. Recommended exploration into lesser-researched SDoH is discussed, and the expansion of this review to other aspects of the TBI continuum is warranted.

Abstract
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.

Abstract
The World Health Organization's Intersectoral Global Action Plan (IGAP) on Epilepsy and Other Neurological Diseases 2022-2031 is a holistic, interdisciplinary, and intersectoral plan with a strong focus on equity and human rights. The IGAP was unanimously approved by all World Health Organization Member States at the 75th World Health Assembly in May 2022 and provides a framework for researchers and clinicians to study and address national and global inadequacies in the evaluation and management of people suffering from neurological disorders and their prevention. While IGAP has applied epilepsy as an entry point for other neurological disorders, advocacy by neurologists and neurosurgeons has broadened it to include diseases with a large and growing global health footprint such as stroke, hydrocephalus, traumatic brain injury, and brain and spine cancers. The IGAP is important to neurosurgeons globally because it provides the first ever roadmap for comprehensively addressing unmet neurological and neurosurgical care in low- and middle-income countries. Furthermore, it creates an opportunity for neurologists and neurosurgeons to scale up services for neurological diseases in tandem. As such, it provides a structure for the neurosurgery community to become involved in global health initiatives at all levels.

Abstract
OBJECTIVE The objective of this study was to analyze the trends in publications on intrathecal baclofen (ITB) therapy. METHODS We searched Elsevier's Scopus database in February 2022 to find articles focused on ITB therapy. Data extracted included citation count, publication year, author's country and income category, journal and its 5-year impact factor, research type, disease requiring ITB, and target population. RESULTS The analysis covered 615 articles from 1985 to 2022. The average citation count per article was 27.47 (95% confidence interval 23.75-31.18) and the mean impact factor was 4.54 (95% confidence interval 3.84-5.24). The majority (76.42%) were primary research, with 8.1% being interventional and 91.9% observational. Even so, one half of the top ten most cited were interventional. Secondary research and case reports made up 12.68% and 10.73% respectively, with narrative reviews making up most of the secondary research (79.48%). Only 1 study conducted a meta-analysis. The United States was the most prolific country. High-income countries published 96.42% of articles. CONCLUSIONS The rising number of ITB articles and citations indicates growing interest and expanding knowledge in this field. However, there's a notable scarcity of research from low- and middle-income countries, particularly those with high prevalence of ITB-treatable diseases. The need for more evidence to overcome potential barriers to ITB implementation is emphasized. Despite an increasing number of publications, a large proportion presented low levels of evidence, such as case reports and narrative reviews, highlighting the need for more rigorous research methods to solidify the evidence base for ITB therapy.

Abstract
Background The effective treatment of high-grade gliomas is a complex problem that requires ubiquitous implementation of sophisticated therapy protocols. The present study aimed to perform population-based analysis of glioblastoma management in lower-middle-income countries. Methods The National Cancer Registry of Ukraine was screened for the records of adult patients with primary glioblastomas diagnosed in 2015-2019. Survival analysis was performed using Kaplan-Meier method and a multivariable Cox model. Results A total of 2973 adult patients with histologically confirmed glioblastoma were included in the study. Mean age of patients was 55.6 ± 11.4 years, males slightly prevailed-1541 (51.8%) cases. The completed clinical protocol including surgery followed by chemoradiotherapy was applied only in 658 (19.0%) patients. The minority of patients 743 (25.0%) were treated at the academic medical centers, where patients were more likely to receive combined treatment 70.1% compared with 57.9% (P = .0001) at the community hospitals. The overall median survival was 10.6 ± 0.2 months, and the 2-year survival rate was 17%. The number of utilized treatment modalities contributed to better survival rates and was associated with lower hazard ratio: Protocol with 2 modalities - 0.62 (P = .0001), 3 modalities - 0.48 (P = .0001). Conclusions The management of glioblastoma in lower-middle-income countries is characterized by insufficient availability of treatment in academic medical centers and low rates of advanced therapy application. Survival analysis showed similar prognostic risk factors and outcomes compared with high-income countries.

Abstract
Bibliometric analyses are a well-established strategy for understanding the dynamics of publications. Aneurysmal subarachnoid hemorrhage (aSAH) is a hot topic in neurology and neurosurgery research. To perform a bibliometric analysis of recent publications within aSAH. Articles addressing aSAH published between 2017 and 2021 were included and had their information extracted from Scopus. A total of 2177 articles were included. The mean number of citations was 6.18 (95%CI = 5.77-6.59). 2021 and 2020 were the most prolific years. World Neurosurgery (N = 389/2,177 articles; 17,87%) was the leading publisher, and American Journal of Neuroradiology had the highest number of citations per article (14.82) among journals with ≥ 10 publications. Primary research (N = 1624/2177) predominated, followed by case reports (N = 434/2,177). Among secondary studies, systematic reviews (N = 78/119) surpassed narrative reviews (N = 41/119). USA led the number of publications (N = 548/2,177 articles; 25.17%), followed by China (N = 358/2,177 articles; 16.44%). High-income countries had a higher number of publications (N = 1624/2177) and more citations per article (6.84) than middle-income countries (N = 553/2177 and 4.25, respectively). There were zero articles from low-income countries. European and North American institutions had the greatest research impact. There was an increase in the number of published articles in the last few years (2020 and 2021). Many studies had a low level of evidence, whereas interventional studies were uncommon.

Abstract
Low- and middle-income countries (LMICs) experience the majority of traumatic brain injuries (TBIs), yet few studies have examined the epidemiology and management strategies of TBI in LMICs. The objective of this narrative review is to discuss the epidemiology of TBI within LMICs, describe the adherence to Brain Trauma Foundation (BTF) guidelines for the management of severe TBI in LMICs, and document TBI management strategies currently used in LMICs. Articles from January 1, 2009 to September 30, 2021 that included patients with TBI greater than 18 years of age in low-, low middle-, and high middle-income countries were queried in PubMed. Search results demonstrated that TBI in LMICs mostly impacts young males involved in road traffic accidents. Within LMICs there are a myriad of approaches to managing TBI with few randomized controlled trials performed within LMICs to evaluate those interventions. More studies are needed in LMICs to establish the effectiveness and appropriateness of BTF guidelines for managing TBI and to help identify methods for managing TBI that are appropriate in low-resource settings. The problem of limited pre- and post-hospital care is a bigger challenge that needs to be considered while addressing management of TBI in LMICs.

Abstract
Severe traumatic brain injury (sTBI) is a condition of increasing epidemiologic concern worldwide. Outcomes are worse as observed in low- and middle-income countries (LMICs) versus high-income countries. Global targets are in place to address the surgical burden of disease. At the same time, most of the published literature and evidence on the clinical approach to sTBI comes from wealthy areas with an abundance of resources. The available paradigms, including the Brain Trauma Foundation guidelines, the Seattle International Severe Traumatic Brain Injury Consensus Conference, Consensus Revised Imaging and Clinical Examination, and multimodality approaches, may fit differently depending on local resources, expertise, and sociocultural factors. A first step toward addressing heterogeneity in practice is to consider comparative effectiveness approaches that can capture actual practice patterns and record short-term and long-term outcomes of interest. Decompressive craniectomy (DC) decreases intracranial pressure burden and can be lifesaving. Nevertheless, completed randomized controlled trials took place within high-income settings, leaving important questions unanswered and making extrapolations to LMICs questionable. The concept of preemptive DC specifically to address limited neuromonitoring resources may warrant further study to establish a benefit/risk profile for the procedure and its role within local protocols of care.

WOMEN'S HEALTH (LONDON, ENGLAND) 2023; 19:17455057231210265. [PMID: 37955275 PMCID: PMC10644749 DOI: 10.1177/17455057231210265] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Revised: 09/25/2023] [Accepted: 10/10/2023] [Indexed: 11/14/2023]
Abstract
Neurological disorders during pregnancy are a substantial threat to women's health, particularly in low- and middle-income countries. Furthermore, a critical shortage of mental health workers and neurologists exacerbates the already pressing issue, where a lack of coordination of respective healthcare among multidisciplinary teams involved in managing these conditions perpetuates the current state of affairs. Financial restrictions and societal stigmas associated with neurological disorders in pregnancy amplify the situation. Addressing these difficulties would necessitate a multifaceted approach comprising investments in healthcare infrastructure, healthcare professional education and training, increased government support for research, and the implementation of innovative care models. Improving access to specialized treatment and coordinated management of antenatal neurological diseases will precipitate improved health outcomes for women and their families in low- and middle-income countries.

Abstract
BACKGROUND The high unmet neurosurgical burden in low- and middle-income countries has necessitated multiple global neurosurgical collaborations. We identified these collaborations and their peer-reviewed journal publications and evaluated them using a modified version of the Framework for Assessment of InteRNational Surgical Success (FAIRNeSS). METHODS A systematic literature review yielded 265 articles describing neurosurgery-focused collaborations. A subset of 101 papers from 17 collaborations were evaluated with the modified FAIRNeSS criteria. Analysis of trends was performed for both individual articles and collaborations. RESULTS Most of the articles were general reviews (64), and most focused on clinical research (115). The leading collaboration focus was workforce and infrastructure development (45%). Composite FAIRNeSS scores ranged from 7/34 to 30/34. Average FAIRNeSS scores for individual articles ranged from 0.25 to 26.75, while collaboration-wide FAIRNeSS score averages ranged from 5.25 to 20.04. There was significant variability within each subset of FAIRNeSS indicators (P value <0.001). Short-term goals had higher scores than medium- and long-term goals (P value <0.001). Collaboration composite scores correlated with the number of papers published (R2 = 0.400, P = 0.007) but not with the number of years active (R2 = 0.072, P = 0.3). Finally, the overall agreement between reviewers was 53.5%, and the overall correlation was 38.5%. CONCLUSIONS Global neurosurgery has no established metrics for evaluating collaborations; therefore, we adapted the FAIRNeSS criteria to do so. The criteria may not be well suited for measuring the success and sustainability of global neurosurgery collaborations, creating a need to develop a more applicable alternate set of metrics.

Abstract
Traumatic brain injury is one of the leading causes of mortality and morbidity in children worldwide. In severe cases, high intracranial pressure is the most frequent cause of death. When first-line medical management fails, the neurosurgical procedure of decompressive craniectomy (DC) has been proposed for controlling intracranial pressure and improving the long-term outcomes for children with severe traumatic brain injury. However, the use of this procedure is controversial. The evidence from clinical trials shows some promise for the use of DC as an effective second-line treatment. However, it is limited by conflicting trial results, a lack of trials, and a high risk of bias. Furthermore, most research comes from retrospective observational studies and case series. This narrative review considers the strength of evidence for the use of DC in both a high income country and low-and-middle income country setting and examine how we can improve study design to better assess the efficacy of this procedure and increase the clinical translatability of results to centers worldwide. Specifically, we argue for a need for further studies with higher pediatric participant numbers, multicenter collaboration, and the use of a more consistent methodology to enable comparability of results among settings.

Abstract
Acute neurologic illnesses (ANI) contribute significantly to the global burden of disease and cause disproportionate death and disability in low-income and middle-income countries (LMICs) where neurocritical care resources and expertise are limited. Shifting epidemiologic trends in recent decades have increased the worldwide burden of noncommunicable diseases, including cerebrovascular disease and traumatic brain injury, which coexist in many LMICs with a persistently high burden of central nervous system infections such as tuberculosis, neurocysticercosis, and HIV-related opportunistic infections and complications. In the face of this heavy disease burden, many resource-limited countries lack the infrastructure to provide adequate care for patients with ANI. Major gaps exist between wealthy and poor countries in access to essential resources such as intensive care unit beds, neuroimaging, clinical laboratories, neurosurgical capacity, and medications for managing complex neurologic emergencies. Moreover, many resource-limited countries face critical shortages in health care workers trained to manage neurologic emergencies, with subspecialized neurocritical care expertise largely absent outside of high-income countries. Numerous opportunities exist to overcome these challenges through capacity-building efforts that improve outcomes for patients with ANI in resource-limited countries. These include research on needs and best practices for ANI management in LMICs, developing systems for effective triage, education and training to expand the neurology workforce, and supporting increased collaboration and data sharing among LMIC health care workers and systems. The success of these efforts in curbing the disproportionate and rising impact of ANI in LMICs will depend on the coordinated engagement of the global neurocritical care community.

Abstract
Objective Neurosurgical guidelines have resulted in improved clinical outcomes and more optimized care for many complex neurosurgical pathologies. As momentum in global neurosurgical efforts has grown, there is little understanding about the application of these guidelines in low- and middle-income countries. Methods A 29-question survey was developed to assess the application of specific recommendations from neurosurgical brain and spinal cord injury guidelines. Surveys were distributed to an international cohort of neurosurgeons and neurotrauma stakeholders. Results A total of 82 of 222 (36.9%) neurotrauma providers responded to the survey. The majority of respondents practiced in low- and middle-income countries settings (49/82, 59.8%). There was a significantly greater mean traumatic brain injury volume in low-income countries (56% ± 13.5) and middle-income countries (46.5% ± 21.3) compared with high-income countries (27.9% ± 13.2), P < 0.001. Decompressive hemicraniectomy was estimated to occur in 61.5% (±30.8) of cases of medically refractory intracranial pressure with the lowest occurrence in the African region (44% ± 37.5). The use of prehospital cervical immobilization varied significantly by income status, with 36% (±35.6) of cases in low-income countries, 52.4% (±35.5) of cases in middle-income countries, and 95.2% (±10) in high-income countries, P < 0.001. Mean arterial pressure elevation greater than 85 mm Hg to improve spinal cord perfusion was estimated to occur in 71.7% of cases overall with lowest occurrence in Eastern Mediterranean region (55.6% ± 24). Conclusions While some disparities in guideline implementation are inevitably related to the availability of clinical resources, other differences could be more quickly improved with accessibility of current evidence-based guidelines and development of local data.

Abstract
BACKGROUND Neurosurgery-specific research plays a critical role in improving outcomes in patients with neurosurgical diseases. Despite the high burden of neurosurgical diseases in Ethiopia, little is known about types of neurosurgical research from Ethiopia. The goal of this scoping review is to assess the quantity and types of neurosurgical research published in peer-reviewed journals by authors from Ethiopia. METHODS PubMed, CINAHL, Embase, and Scopus were searched for Ethiopian neurosurgery literature published from 2001 to 2021. We selected articles based on the following criteria: articles must 1) discuss topics within neurosurgery and 2) focus on clinical practice and/or public health in Ethiopia. We collected data on research originality, study designs, and clinical versus public health research. The frequencies and percentages of categorical variables were reported. All analyses were conducted using Jamovi software. RESULTS Of the 362 results, 89 neurosurgical research articles were included in the final analysis. Of the 89 articles, case reports/series were most common (28.7%), followed by retrospective cohort (20.7%) and prospective cohort studies (18.4%). There were 8 literature reviews (9.2%) and 1 systematic review and meta-analysis (1.1%). No randomized controlled trial was found. Of all articles, 66 (75.9%) focused on clinical practice, and 21 (23.6%) were related to the public health aspect of neurosurgery. Forty-two articles (48.3%) included authors only from Ethiopia; 37 articles (42.5%) involved collaboration between Ethiopian and authors from another country, and 8 articles (9.2%) did not have Ethiopian authors. CONCLUSIONS Neurosurgery research from Ethiopia is lacking, despite its high disease burden. Case reports/series and cohort studies remain the mainstay, with few systematic reviews and no randomized controlled trial. International collaboration accounts for approximately half of Ethiopian neurosurgery research output. Further research support and infrastructure should be developed to encourage neurosurgery articles from Ethiopia.

Abstract
The emerging field of global oral and maxillofacial surgery (OMS) aims to improve worldwide access to safe, timely, and affordable OMS care. However, there exists a dearth of literature thoroughly detailing the scope of academic global OMS collaborations between high-income countries (HICs) and low- and/or lower middle-income countries (LICs/LMICs). This scoping review was performed to characterize the landscape of global academic OMS collaborations between HICs and LICs/LMICs. A five-stage methodological framework was used. Academic global OMS collaborations from 1996 to 2020 were identified via an electronic database and grey literature review. A total 1318 articles were identified on December 17, 2020. Following the application of inclusion and exclusion criteria, 71 articles describing 81 unique global OMS academic collaborations were included in the final analysis. The most common HIC was the United States (44.4%); the majority of LIC/LMICs were within Africa (45.8%). Of the total interventions, 89.6% improved LIC/LMIC capacity development, and surgical (43.8%) interventions were the most common. By serving as a central report on current and past academic collaborations in global OMS, this review helps identify areas in need of surgical capacity building, lays the foundation for future research efforts on the topic, and serves as a resource for individuals aiming to become involved in global OMS.

Abstract
IntroductionNeurosurgical equipment donation from high-income countries (HICs) to low-and-middle income countries (LMICs) exists. However, there is currently no published literature on whether there is a need for neurosurgical equipment donations or how to design equipment donation programmes that meet the needs of LMIC neurosurgeons. The primary aims of this study were to explore: (1) the need for the donation of neurosurgical equipment from the UK and Ireland to LMICs within the African continent, and (2) the ways through which neurosurgical equipment donations could meet the needs of LMIC neurosurgeons.MethodsThis was a qualitative study using semi-structured, one-on-one, audio-recorded interviews. Purposive sampling was used to recruit and interview consultants or attending neurosurgeons from Ireland, the UK and LMICs in Africa in a continuous process until data saturation. Interviews were conducted by members of the Association of Future African Neurosurgeons during March 2021. Qualitative analysis used a thematic approach using open and axial coding.ResultsFive HIC and 3 LMIC neurosurgeons were interviewed. Five overarching themes were identified: (1) inequality of access to neurosurgical equipment, (2) identifying specific neurosurgical equipment needs, (3) importance of organisations, (4) partnerships between LMIC and HIC centres, and (5) donations are insufficient in isolation.ConclusionThere is a need for greater access to neurosurgical equipment in LMICs. It is unclear if neurosurgical equipment donations are the optimal solution to this issue. Other solutions that are not linked to dependency need to be explored and executed. Collaborative relationships between LMICs and HICs better ensures that neurosurgical equipment donations meet the needs of the recipients. These relationships may be best created within an organisation framework that has the logistical capabilities of coordinating international equipment donation and providing a quality control measure.

Abstract
Background Systemic sclerosis (SSc) is a rare detrimental disease warranting global research efforts. Evaluating how socio-economic factors impact country research output on SSc could help to identify solutions advancing research. Methods Publication production on SSc during 1969–2018 and data for structural and policy factors for WHO member countries were collected from public sources. Associations between SSc research output and country-level factors were investigated through panel regression. Difference-in-differences analysis further assessed the causal effects of rare disease legislation. Results SSc publications demonstrated exponential growth (r = 0.9410, as against an r = 0.8845 after linear adjustment), but were concentrated in high-income countries (HICs). Ten countries, nine of which were HICs, published 12,261 (77.5%) SSc publications but another 87 countries produced none. Gross domestic products (GDP), population and expenditure on research and development were positively associated with SSc publications (p < 0.001). Higher health expenditure was only found to be associated with increased SSc publications in HICs (p < 0.001). Rare disease legislation increased annual publication production by 62.8% (95% CI 0.390–0.867; p < 0.001) averagely. In middle-income countries (MICs), the effect was especially swift and lasting. No significant impact was found with GDP per capita, female percentage, and political indicators. Conclusions SSc research output increased over time with substantial country disparities. Effective health policies facilitating research should be expanded especially among MICs to accelerate research advancement.

Abstract
OBJECTIVES Low-income and-middle-income countries (LMICs) are increasing investment in research and development, yet there remains a paucity of neurotrauma research published by those in LMICs. The aim of this study was to understand neurosurgeons' experiences of, aspirations for, and ability to conduct and disseminate clinical research in LMICs. DESIGN This was a two-stage inductive qualitative study situated within the naturalistic paradigm. This study committed to an interpretivist way of knowing (epistemology), and considered reality subjective and multiple (ontology). Data collection used online methods and included a web-based survey tool for demographic data, an asynchronous online focus group and follow-up semistructured interviews. Data were analysed using Braun and Clarke's Reflexive Thematic Analysis supported by NVivo V.12. SETTING LMICs. PARTICIPANTS In April-July 2020, 26 neurosurgeons from 11 LMICs participated in this study (n=24 in the focus groups, n=20 in follow-up interviews). RESULTS The analysis gave rise to five themes: The local landscape; creating capacity; reach and impact; collaborative inquiry; growth and sustainability. Each theme contained an inhibitor and stimulus to neurosurgeons conducting and disseminating clinical research, interpreted as 'the neurosurgical research potential in LMICs'. Mentorship, education, infrastructure, impact and engagement were identified as specific accelerators. Whereas lack of generalisability, absence of dissemination and dissemination without peer review may desensitise the impact of research conducted by neurosurgeons. CONCLUSION The geographical, political and population complexities make research endeavour challenging for neurosurgeons in LMICs. Yet in spite of, and because of, these complexities LMICs provide rich opportunities to advance global neurosurgery. More studies are required to evaluate the specific effects of accelerators of research conducted by neurosurgeons and to understand the effects of desensitisers on high-quality, high-impact clinical research.

International Neurotrauma Training Based on North-South Collaborations: Results of an Inter-institutional Program in the Era of Global Neurosurgery. Front Surg 2021; 8:633774. [PMID: 34395505 PMCID: PMC8358677 DOI: 10.3389/fsurg.2021.633774] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2020] [Accepted: 07/05/2021] [Indexed: 11/13/2022] Open
Abstract
Objective: Shortage of general neurosurgery and specialized neurotrauma care in low resource settings is a critical setback in the national surgical plans of low and middle-income countries (LMIC). Neurotrauma fellowship programs typically exist in high-income countries (HIC), where surgeons who fulfill the requirements for positions regularly stay to practice. Due to this issue, neurosurgery residents and medical students from LMICs do not have regular access to this kind of specialized training and knowledge-hubs. The objective of this paper is to present the results of a recently established neurotrauma fellowship program for neurosurgeons of LMICs in the framework of global neurosurgery collaborations, including the involvement of specialized parallel education for neurosurgery residents and medical students. Methods: The Global Neurotrauma Fellowship (GNTF) program was inaugurated in 2015 by a multi-institutional collaboration between a HIC and an LMIC. The course organizers designed it to be a 12-month program based on adapted neurotrauma international competencies with the academic support of the Barrow Neurological Institute at Phoenix Children's Hospital and Meditech Foundation in Colombia. Since 2018, additional support from the UK, National Institute of Health Research (NIHR) Global Health Research in Neurotrauma Project from the University of Cambridge enhanced the infrastructure of the program, adding a research component in global neurosurgery and system science. Results: Eight fellows from Brazil, Venezuela, Cuba, Pakistan, and Colombia have been trained and certified via the fellowship program. The integration of international competencies and exposure to different systems of care in high-income and low-income environments creates a unique environment for training within a global neurosurgery framework. Additionally, 18 residents (Venezuela, Colombia, Ecuador, Peru, Cuba, Germany, Spain, and the USA), and ten medical students (the United Kingdom, USA, Australia, and Colombia) have also participated in elective rotations of neurotrauma and critical care during the time of the fellowship program, as well as in research projects as part of an established global surgery initiative. Conclusion: We have shown that it is possible to establish a neurotrauma fellowship program in an LMIC based on the structure of HIC formal training programs. Adaptation of the international competencies focusing on neurotrauma care in low resource settings and maintaining international mentoring and academic support will allow the participants to return to practice in their home-based countries.

Abstract
INTRODUCTION Low-income and middle-income countries (LMICs) face the greatest burden of neurotrauma. However, most of the research published in scientific journals originates from high-income countries, suggesting those in LMICs are either not engaging in research or are not publishing it. Evidence originating in high-income countries may not be generalisable to LMICs; therefore, it is important to nurture research capacity in LMICs so that a relevant evidence base can be developed. However, little is published about specific challenges or contextual issues relevant to increasing research activity of neurosurgeons in LMICs. Therefore, the aim of this study was to understand neurosurgeons' experiences of, aspirations for and ability to conduct and disseminate clinical research in LMICs. METHODS AND ANALYSIS This is a pragmatic qualitative study situated within the naturalistic paradigm using focus groups and interviews with a purposive sample of neurosurgeons from LMICs. First, we will conduct asynchronous online focus groups with 36 neurosurgeons to broadly explore issues relevant to the study aim. Second, we will select 20 participants for follow-up semistructured interviews to explore concepts in more depth and detail than could be achieved in the focus group. Interviews will be audio-recorded and transcribed verbatim. A thematic analysis will be conducted following Braun and Clarke's six stages and will be supported by NVIVO software. ETHICS AND DISSEMINATION The University of Cambridge Psychology Research Ethics Committee reviewed this study and provided a favourable opinion in January 2020 (REF PRE.2020.006). Participants will provide informed consent, be able to withdraw at any time and will have their contributions kept confidential. The findings of the study will be shared with relevant stakeholders and disseminated in conference presentations and journal publications.
