RESUMEN

BACKGROUND: The Caribbean is a unique region of islands and cays home to nearly 43 million people. A significant challenge facing this population is the burden of traumatic brain injury, which disproportionately affects younger individuals and carries a significant economic burden. A preventive measure to reduce this burden is consistent wearing of helmets. This study aims to assess TBI prevention through helmet safety in Caribbean nations in order to demonstrate the regional impact of public health solutions. METHODS: We assess the member states of the Caribbean Community (CARICOM) and sought to evaluate CARICOM nations' TBI prevention through helmet safety with relation to public health, policy, laws, infrastructure, and regulations. We produced the Rolle Scoring System (RSS) to ascertain the influence of governance around helmet safety for TBI prevention. The RSS aims to provide a quantifiable method of how well a CARICOM nation is performing in efforts to reduce TBI. The RSS is broken down into 2 categories, with scores ranging from 1 (worst) to 5 (best). The range of possible scores a CARICOM nation could receive was 8 to 40. RESULTS: Fourteen CARICOM nations were ultimately incorporated into our analysis. From the initial cohort, 3 were removed. These nations were Anguilla, Saint Kitts & Nevis, and Montserrat. We analyzed values derived from the RSS, finding a mean Rolle score of 22. We further subdivided the nations into low Rolle score (8-24) and high Rolle score (>24). Trinidad and Tobago had the highest Rolle score at 29. Haiti was found to have the lowest Rolle score at 8. CONCLUSION: Several Caribbean nations have demonstrated leadership pertaining to TBI prevention through helmet safety. The regional momentum of helmet safety in the Caribbean can serve as a model for other geographical regional blocs that share interests and culture to consider comprehensive approaches to public health challenges.

RESUMEN

Intracranial abscess in the pediatric population is an overall rare occurrence-4 in a million. The most common predisposing factor is underlying cyanotic congenital heart disease (CCHD), which is associated with ~ 30% of all cases. We present an unusual case of cerebral abscess in a 17-month-old female with partially treated Tetralogy of Fallot and fever of unknown origin without associated neurologic symptoms. We propose a low threshold for intracranial imaging as part of the fever of unknown origin work-up in children with underlying cyanotic congenital heart disease.

RESUMEN

OBJECTIVE: Achieving rigid spinal fixation can be challenging in patients with cancer-related instability, as factors such as osteopenia, radiation, and immunosuppression adversely affect bone quality. Augmenting pedicle screws with cement is a strategy to overcome construct failure. This study aimed to assess the safety and efficacy of cement augmentation with fenestrated pedicle screws in patients undergoing posterior, open thoracolumbar surgery for spinal metastases. METHODS: A retrospective review was performed for patients who underwent surgery for cancer-related spine instability from 2016 to 2019 at the Massachusetts General Hospital. Patient demographics, surgical details, radiographic characteristics, patterns of cement extravasation, complications, and prospectively collected Patient-Reported Outcomes Measurement Information System Pain Interference and Pain Intensity scores were analyzed using descriptive statistics. Logistic regression was performed to determine factors associated with cement extravasation. RESULTS: Sixty-nine patients underwent open posterior surgery with a total of 502 cement-augmented screws (mean 7.8 screws per construct). The median follow-up period for those who survived past 90 days was 25.3 months (IQR 10.8-34.6 months). Thirteen patients (18.8%) either died within 90 days or were lost to follow-up. Postoperative CT was performed to assess the instrumentation and patterns of cement extravasation. There was no screw loosening, pullout, or failure. The rate of cement extravasation was 28.9% (145/502), most commonly through the segmental veins (77/145, 53.1%). Screws breaching the lateral border of the pedicle but with fenestrations within the vertebral body were associated with a higher risk of leakage through the segmental veins compared with screws without any breach (OR 8.77, 95% CI 2.84-29.79; p < 0.001). Cement extravasation did not cause symptoms except in 1 patient who developed a symptomatic thoracic radiculopathy requiring decompression. There was 1 case of asymptomatic pulmonary cement embolism. Patients experienced significant pain improvement at the 3-month follow-up, with decreases in Pain Interference (mean change 15.8, 95% CI 14.5-17.1; p < 0.001) and Pain Intensity (mean change 28.5, 95% CI 26.7-30.4; p < 0.001). CONCLUSIONS: Cement augmentation through fenestrated pedicle screws is a safe and effective option for spine stabilization in the cancer population. The risk of clinically significant adverse events from cement extravasation is very low.

RESUMEN

INTRODUCTION: Pediatric gunshot wounds (GSWs) to the head are not well studied in the literature, especially in civilians. With a dearth of case-based and clinically relevant information, pediatric neurosurgeons may be challenged when considering the risks and benefits of removing retained bullet fragments in different intracranial locations. We explore the literature and highlight the key factors in the surgical decision-making case of a 16-year-old girl with GSW to the visual cortex. CASE REPORT: A 16-year-old girl was shot in the head in a parieto-occipital trajectory with the bullet crossing midline, lodging in the occipital lobe into the straight sinus. Her initial Glasgow Coma Scale was 7, and she was urgently stabilized with intracranial pressure monitoring and external ventricular drainage. She underwent craniectomy, debridement, and irrigation and then a reoperation for further debridement and culture 2 weeks later for persistent fevers; cultures remained negative. The retained bullet was not removed. At 18 months post-injury, she had normal speech and motor function, moderate memory dysfunction, and 3-quadrant field loss with retained macular vision. DISCUSSION/CONCLUSION: Pediatric penetrating GSWs to the head may be challenging to manage since literature is sparse. In this case, the primary focus of management was to maintain normal intracranial pressure, reduce risk of infection, and preserve potentially viable visual cortex. In the civilian context of available antibiotics and serial imaging, it may be possible to manage retained bullets conservatively without delayed complications.

RESUMEN

Objective: We sought to identify people who survived firearm suicide attempts to describe the acute stressors, substance use, and mental health conditions related to the attempt. Background: Most firearm deaths in the United States are the result of suicide. Because firearm suicide attempts have a case fatality rate of approximately 90%, little is known about the precipitating factors that lead to firearm suicide attempts. Methods: We conducted a retrospective case series of patients admitted to a large hospital system between 2000 and 2019 who survived intentional, self-inflicted gunshot wounds to the head. Through the electronic medical record, we collected information about acute stressors, substance use, and mental health diagnoses before or at the time of the suicide attempt. Results: Thirty-four patients were included in the study cohort. Patients were predominantly White (74%) and male (88%), with a mean age of 44 (range, 14-82). Nineteen (56%) patients were acutely intoxicated with alcohol upon hospitalization and 17 (50%) patients had a positive urine drug screen. Acute stressors involving interpersonal relationships (53%), work/school (32%), and legal disputes (18%), among others, were documented in 82% of patients. Most patients (65%) had been diagnosed with depression before their index hospitalization. Most patients were discharged to an acute rehabilitation center (41%) or an inpatient psychiatric facility (41%). Conclusions: Acute stress and alcohol intoxication were common in this cohort of patients who attempted suicide using firearms. These data offer an ability to learn from the experience of survivors of firearm suicide attempts, a rare population.

RESUMEN

Introduction: Global access to electronic medical records (EMRs) continues to grow, however many countries including those within the Caribbean Community (CARICOM) lack access to this system. Minimal research investigating EMR use in this region exists. Research question: How does limited EMR access impact neurosurgical care within the CARICOM? Materials and methods: The Cochrane Library, EMBASE, Scopus, PubMed/MEDLINE databases, and grey literature were queried for studies addressing this issue within the CARICOM and low- and/or middle-income countries (LMICs). A comprehensive search for hospitals within the CARICOM was performed and responses to a survey inquiring about neurosurgery availability and EMR access within each facility were recorded. Results: 26 out of 87 surveys were returned leading to a response rate of 29.0%. Among the survey respondents, 57.7% stated neurosurgery was provided at their facility; however, only 38.4% admitted to using an EMR system. Paper charting was the primary means of record keeping for the majority of the facilities (61.5%). The most frequently reported barriers stalling EMR implementation were financial limitations (73.6%) and poor internet access (26.3%). A total of 14 articles were included in the scoping review. Results from these studies suggest that limited EMR access contributes to suboptimal neurosurgical outcomes within the CARICOM and LMICs. Discussion and conclusion: This paper is the first to address the impact that limited EMR has on neurosurgical outcomes in the CARICOM. The lack of research addressing this issue also highlights the need for ongoing efforts to increase research output focused on EMR accessibility and neurosurgical outcomes in these countries.

RESUMEN

Introduction: Traumatic brain injury (TBI) is a significant cause of morbidity and mortality in the Caribbean as well as globally. Within the Caribbean, the prevalence of TBI is approximately 706 per 100,000 persons - one of the highest rates per capita in the world. Research question: We aim to assess the economic productivity lost due to moderate to severe TBI in the Caribbean. Material and methods: The annual cost of economic productivity lost in the Caribbean from TBI was calculated from four variables: (1) the number of people with moderate to severe TBI of working age (15-64 years), (2) the employment-to-population ratio, (3) the relative reduction in employment for people with TBI, and (4) per capita Gross Domestic Product (GDP). Sensitivity analyses were performed to evaluate whether the uncertainty of the TBI prevalence data result in substantive changes in the productivity losses. Results: Globally, there was an estimated 55 million (95% UI 53, 400, 547 to 57, 626, 214) cases of TBI in 2016 of which 322,291 (95% UI 292,210 to 359,914) were in the Caribbean. Using GDP per capita, we calculated the annual cost of potential productivity losses for the Caribbean to be $1.2 billion. Discussion and conclusion: TBI has a significant impact on economic productivity in the Caribbean. With upwards of $1.2 billion lost in economic productivity from TBI, there is an urgent need for appropriate prevention and management of this disease by upscaling neurosurgical capacity. Neurosurgical and policy interventions are necessary to ensure the success of these patients in order to maximize economic productivity.

RESUMEN

BACKGROUND: The neurosurgical workforce in the Caribbean and surrounding countries is largely unknown due to the diversity in cultural, linguistic, political, financial disparities, and colonial history between the countries. About 45 neurosurgeons serve 16 million people in the Caribbean Community and Common Market, a trade alliance including most Caribbean nations. We aimed to understand the current scope of neurosurgical workforce in this region while highlighting any system challenges and potential solutions for upscaling the workforce. METHODS: We surveyed neurosurgeons within Caribbean countries and surrounding countries online using qualitative and quantitative methods via Qualtrics. RESULTS: Of the 38 countries within the Caribbean and surrounding countries, 26 (68%) were surveyed and of which 18 (69%) replied. In total, 172 regional neurosurgeons were identified, of which 61 (35%) replied-with a majority of general neurosurgeons (56%). Remarkably, the majority of countries failed to meet the threshold workforce density for safe health care-either expressed by full-time equivalent neurosurgeons or neurosurgical centers (see table). Most neurosurgical practices confirmed receiving or sending medical referrals. If so, most referrals took longer than 8 hours without significant difference regarding the destination. Lastly, challenges confronting neurosurgical advancement were found in the following: technology and equipment (40%), trained personnel (31%), hospital or medical center infrastructure (14%), neurosurgical education, and training (44%). CONCLUSIONS: To our knowledge, this is the first qualitative and quantitative study exploring the current status of the neurosurgical workforce within the Caribbean and surrounding countries. Identifying resources and challenges can contribute to improving regionalized neurosurgical care.

RESUMEN

BACKGROUND: Pediatric cranial trauma is the leading cause of acquired death and disability in children worldwide. However, trauma resources vary widely among countries. We sought to compare management and timely access to care between a level 1 U.S. pediatric trauma center and a tertiary referral hospital in a lower-middle-income country to assess whether system and resource differences influence care and outcomes. METHODS: We compared data from 214 pediatric head trauma admissions to Philippine General Hospital (Manila) with 136 children from the TRACK-TBI pediatrics study cohort at Massachusetts General Hospital (MGH). Admitted MGH patients were compared with the Philippine cohort regarding demographics; mechanism of injury; times to neurosurgical consult, imaging, and surgery; in-hospital mortality; and length of hospitalization. RESULTS: Age (9 years), gender distribution (67% male), and presenting Glasgow Coma Scale scores were similar (P = 0.10) between sites. More children had intracranial injury in the Philippine cohort (73% vs. 60%; n = 319) and more underwent neurosurgery (27% vs. 4%). Times to consult, imaging, and surgery were longer in the Philippines (12.3 vs. 6.5, 12.0 vs. 2.8, and 45.4 vs. 5.6 hours, respectively). In-hospital mortality across all admissions was similar between cohorts (3% vs. 0%; P = 0.09), but significantly higher in the most severe Philippines cases (31% vs. 0%, P=0.04). Length of stay was longer (5 vs. 2 days; P < 0.001) in the Philippine cohort. CONCLUSIONS: High-income country status correlated with faster care, shorter hospitalizations, and better outcomes among severe cases. Prompt care through sophisticated trauma system implementation may improve pediatric health in resource-limited settings.

RESUMEN

To elucidate the pathogenesis of vein of Galen malformations (VOGMs), the most common and severe congenital brain arteriovenous malformation, we performed an integrated analysis of 310 VOGM proband-family exomes and 336,326 human cerebrovasculature single-cell transcriptomes. We found the Ras suppressor p120 RasGAP ( RASA1 ) harbored a genome-wide significant burden of loss-of-function de novo variants (p=4.79×10 -7 ). Rare, damaging transmitted variants were enriched in Ephrin receptor-B4 ( EPHB4 ) (p=1.22×10 -5 ), which cooperates with p120 RasGAP to limit Ras activation. Other probands had pathogenic variants in ACVRL1 , NOTCH1 , ITGB1 , and PTPN11 . ACVRL1 variants were also identified in a multi-generational VOGM pedigree. Integrative genomics defined developing endothelial cells as a key spatio-temporal locus of VOGM pathophysiology. Mice expressing a VOGM-specific EPHB4 kinase-domain missense variant exhibited constitutive endothelial Ras/ERK/MAPK activation and impaired hierarchical development of angiogenesis-regulated arterial-capillary-venous networks, but only when carrying a "second-hit" allele. These results illuminate human arterio-venous development and VOGM pathobiology and have clinical implications.

RESUMEN

To elucidate the pathogenesis of vein of Galen malformations (VOGMs), the most common and most severe of congenital brain arteriovenous malformations, we performed an integrated analysis of 310 VOGM proband-family exomes and 336,326 human cerebrovasculature single-cell transcriptomes. We found the Ras suppressor p120 RasGAP (RASA1) harbored a genome-wide significant burden of loss-of-function de novo variants (2042.5-fold, p = 4.79 x 10-7). Rare, damaging transmitted variants were enriched in Ephrin receptor-B4 (EPHB4) (17.5-fold, p = 1.22 x 10-5), which cooperates with p120 RasGAP to regulate vascular development. Additional probands had damaging variants in ACVRL1, NOTCH1, ITGB1, and PTPN11. ACVRL1 variants were also identified in a multi-generational VOGM pedigree. Integrative genomic analysis defined developing endothelial cells as a likely spatio-temporal locus of VOGM pathophysiology. Mice expressing a VOGM-specific EPHB4 kinase-domain missense variant (Phe867Leu) exhibited disrupted developmental angiogenesis and impaired hierarchical development of arterial-capillary-venous networks, but only in the presence of a "second-hit" allele. These results illuminate human arterio-venous development and VOGM pathobiology and have implications for patients and their families.

RESUMEN

OBJECTIVE: Approximately 69 million people suffer from traumatic brain injury (TBI) annually. Patients with isolated epidural hematomas (EDH) with access to timely surgical intervention often sustain favorable outcomes. Efforts to ensure safe, timely, and affordable access to EDH treatment may offer tremendous benefits. METHODS: A comprehensive literature search was conducted. A random-effects model was used to pool the outcomes. Studies were further categorized into groups by World Bank Income classification: high-income countries (HICs) and low- and middle-income countries (LMICs). RESULTS: Forty-nine studies were included, including 36 from HICs, 12 from LMICs, and 1 from HIC / LMIC. Incidence of EDH amongst TBI patients 8.2 % (95 % CI: 5.9,11.2), including 9.2 % (95 %CI 6.4,13.2) in HICs and 5.8 % (95 % CI: 3.1,10.7) in LMICs (p = 0.20). The overall percent male was 73.7 % and 47.4 % were caused by road traffic accidents. Operative rate was 76.0 % (95 %CI: 67.9,82.6), with a numerically lower rate of 74.2 % (95 %CI: 64.0,81.8) in HICs than in LMICs 82.9 % (95 %CI: 65.4,92.5) (p = 0.33). This decreased to 55.5 % after adjustment for small study effect. The non-operative mortality (5.3 %, 95 %CI: 2.2,12.3) was lower than the operative mortality (8.3 %, 95 %CI: 4.6,14.6), with slightly higher rates in HICs than LMICs. This relationship remained after adjustment for small study effect, with 9.3 % operative mortality compared to 6.9 % non-operative mortality. CONCLUSION: With an overall EDH incidence of 8.2 % and an operative rate of 55.5 %, 3.1 million people worldwide require surgery for traumatic EDH every year, most of whom are in prime working age. Given the favorable prognosis with treatment, traumatic EDH is a strong investment for neurosurgical capacity building.

RESUMEN

Objective: To assess the clinical, racial, and social characteristics of victims of Gunshot wounds (GSWs) to the head and assess for associations between these factors and outcomes. Summary Background Data: Previous literature has not focused on the association of race and socioeconomic factors with these specific injuries. Methods: We identified patients with GSWs to the head who presented to 2 urban academic medical centers between 1998 and 2020, and extracted patient-level demographic data, information about the clinical and surgical course, and outcomes at discharge and follow-up. Results: The cohort included 250 patients, 90% (n = 226) of whom were male, with a mean age of 28 years. Forty-five percent were white (n = 112), 19% Black (n = 48), 18% Latinx (n = 45), with 6% "other" (n = 16), and 12% "unknown" (n = 29). The majority of patients presented with assault-related trauma (n = 153, 61%) as compared to self-inflicted injuries (n = 97, 39%). Across the entire cohort, sex, age, race, and median income by ZIP code were not significant predictors of outcome. Victims of assault by GSW to the head were more likely to be age 18 or younger (OR 5.26, P = 0.01), between the ages of 19 and 33 years (OR 4.7, P = 0.001), Black (OR 6.66, P < .001), and Latinx (OR 2.65, P = 0.03). Most patients (n = 155, 63%) had a poor functional outcome (modified Rankin Score 3-6) at discharge. Conclusion: Age, race, and income status were not independent predictors of mortality or functional outcome at discharge in our population. Assault-related GSWs to the head mostly involved young Black or Latinx men of lower socioeconomic status, while self-inflicted injuries were largely seen in older white men.

RESUMEN

Introduction: Neurological disorders are one of the leading causes of death and disability adjusted life years (DALYs). Efforts have been made to increase the neurosurgical workforce in an attempt to address the global disease burden. Despite these efforts, there continues to be a shortage of neurosurgeons in both high-income countries (HICs) and low-and middle-income countries (LMICs). Research question: The aim of the study was to identify the barriers to neurosurgical training in LMICs and HICs. Materials and methods: We administered an electronic survey targeting medical students, neurosurgery residents, and recent neurosurgery graduates from 69 countries in both HICs and LMICs. Questions were framed to assess barriers to training. Results: Of the 198 responses received (31.3% response rate), 72% identified as male, 27% female, and 0.5% as non-binary gender. 33 respondents were from HICs and 165 were from LMICs. 70.1% of respondents reported no availability of dissection labs in their home institutions. There was a significant difference in availability of subspecialty training between LMICs and HMICs (p â€‹= â€‹0.001) but no significance was seen for competitiveness of programs (p â€‹= â€‹0.473). Discussion and conclusion: There are limitations to our study: it is not comprehensive of training programs globally, there is sampling bias, especially among LMICs, and the accuracy of responses is unclear. Nonetheless, our results highlight the need for a deliberate focus on designing and implementing both short and long term goals in tackling barriers to access to neurosurgical training, with a conscientious effort to involve interested stakeholders and governments to invest in the training and education of their neurosurgical workforce.

RESUMEN

Introduction: Opportunities for in-country neurosurgical training are severely limited in LMICs, particularly due to rigorous educational requirements and prohibitive upfront costs. Research question: This study aims to evaluate financial barriers aspiring neurosurgeons face in accessing and completing neurosurgical training, specifically in LMICs, in order to determine the barriers to equitable access to training. Material and methods: In order to assess the financial costs of accessing and completing neurosurgery residency, an electronic survey was administered to those with the most recent experience with the process: aspiring neurosurgeons, neurosurgical trainees, and recent neurosurgery graduates. We attempted to include a broad representation of World Health Organization (WHO) geographic regions and World Bank income classifications in order to determine differences among regions and countries of different income levels. Results: Our survey resulted in 198 unique responses (response rate 31.3%), of which 83% (n â€‹= â€‹165) were from LMICs. Cost data were reported for 48 individual countries, of which 26.2% were reported to require trainees to pay for their neurosurgical training. Payment amounts varied amongst countries, with multiple countries having costs that surpassed their annual gross national income as defined by the World Bank. Discussion and conclusions: Opportunities for formal neurosurgical training are severely limited, especially in LMICs. Cost is an important barrier that can not only limit the capacity to train neurosurgeons but can also perpetuate inequitable access to training. Additional investment by governments and other stakeholders can help develop a sufficient workforce and reduce inequality for the next generation of neurosurgeons worldwide.

RESUMEN

Background Traumatic brain injury (TBI) has a disproportionately greater impact in low- and middle-income countries (LMICs). One strategy to reduce the burden of disease in LMICs is through the implementation of a trauma registry that standardizes the assessment of each patient's management of care. Objective This study aims to ascertain the interest of Latin America and the Caribbean (LAC) nations in establishing a shared neurotrauma registry in the regional block, based on an existing framework for collaboration. Methods A descriptive review was performed regarding the interests of LAC nations in implementing a shared neurotrauma registry in their region. We convened a meeting with seven Caribbean and five Latin American nations. Results One hundred percent ( n = 12) of the LAC representatives including neurosurgeons, neurointensivists, ministers of health, and chief medical officers/emergency medical technicians (EMTs) agreed to adopt the registry for tracking the burden of TBI and associated pathologies within the region. Conclusion The implementation of a neurotrauma registry can benefit the region through a shared database to track disease, improve outcomes, build research, and ultimately influence policy.

RESUMEN

OBJECTIVE: Pediatric postoperative neurosurgical care is an essential component of a child's treatment pathway. It is important to better understand how neurosurgeons in lower middle-income countries (LMICs) have been able to address socioeconomic and systemic factors to improve their patients' access to quality pediatric postoperative neurosurgical care. We aim to characterize the pediatric neurosurgical postoperative system in place in Zambia and to discuss how these efforts have been implemented to improve outcomes and address socioeconomic barriers to accessing health care. METHODS: We acquired a patient list of 90 tenants of House of Hope (HOH)-an out-of-hospital center caring for children awaiting surgery, as well as those recovering from surgery. Of the patient list, 44 patients qualified for our study. Survey responses and occurrence of demographic and clinical characteristics were calculated. Non-normally distributed variables (age) were reported by median and interquartile range (IQR). Dichotomous variables were presented as percentages. Fisher's Exact test was applied to compare categorical data and hospital re-admission. A P-value of <0.05 was considered significant. RESULTS: Our study demonstrates two key findings: (1) low 30-day hospital re-admission rate of 9% and (2) favorable postoperative experience by patient families. Of the 44 patients, a majority were 1-year-old children (n = 31, 70%) and female (n = 24, 55%) (IQR 1-2 years). Presenting conditions included: hydrocephalus only (n = 35, 80%), hydrocephalus and myelomeningocele (n = 5, 11%), myelomeningocele only (n = 2, 5%), cerebral palsy (n = 1, 2%), and encephalocele (n = 1, 2%). Half (n = 22, 50%) of the patients lived in east Zambia, 8 (18%) lived in central, 8 (18%) in north, 5 (11%) in south, and 1 (2%) in west Zambia. CONCLUSIONS: We report the first qualitative and quantitative analysis of postoperative care for LMIC pediatric neurosurgical patients in the academic literature. Quality, patient-centered postoperative pediatric neurosurgical care that is rooted in addressing socioeconomic determinants of health produces good outcomes in LMICs.

RESUMEN

Five million neurosurgical cases go untreated each year. This is in part due to the lack of neurosurgical care providers. The World Federation of Neurosurgical Societies has spearheaded efforts to monitor the number of neurosurgical providers around the globe since 2016. In this perspective, we discuss why, when, and how the neurosurgical workforce should be measured.
