RESUMO

INTRODUCTION: Three million African patients need a neurosurgical consultation every year, but there are not enough neurosurgeons to meet this need. Efforts have been made to increase the neurosurgical capacity through the creation of training programs in Africa. Although these programs have been successful, there is still a long way to go. Aspiring African neurosurgeons (AANs) will become neurosurgeons in the future if they are given the resources and opportunities. The authors set out to understand the perceptions, needs, and difficulties faced by AANs. METHODS: An e-survey containing 45 questions was created using Google Forms and distributed via social media. The survey was anonymous, and it was distributed from June 2, 2020, to June 16, 2020. Summary descriptive statistics and the Chi-Square test were calculated. The p-value was considered to be significant below .05. RESULTS: A total of 221 AANs aged 23.5 ± 3.3 years and from 22 African countries responded to the survey. Most were male (66.1%) and medical students (84.6%). Few had assisted a neurosurgical intervention in-person (24.9%), had a mentor (29.0%) or attended a journal club (10.3%). A small proportion was unwilling to train in their home country (19.5%) or a neighboring country (16.3%). The top three reasons for choosing neurosurgery were prestige, advice from a family member, and projected income. Also, respondents felt neurosurgery was expensive. CONCLUSION: AANs are passionate about neurosurgery but lack the information, guidance, or opportunities to fulfil their wish.

RESUMO

BACKGROUND: Over the last decade, many advancements have been made in the management of low-grade gliomas (LGGs). Overall survival outcomes are correlated with factors such as postoperative residual volumes and specific tumor biomolecular profiles such as IDH mutation status. It is unclear whether these advancements have benefited LGG patients in Africa. This scoping review protocol outlines how the authors will evaluate the epidemiology, presentations, management and outcomes of LGGs in Africa. METHODS: MEDLINE, Embase and African Journals Online will be searched from database inception to date in order to identify the relevant studies. Patients of all ages with histologically and/or radiologically confirmed LGGs that were managed in an African country will be included. Surgical and chemoradiation management of LGG tumours will be considered. Original research, reviews, commentaries, editorials and case reports will be included. RESULTS: Primary outcomes of the review will include LGG management, morbidity and mortality. Secondary outcomes include epidemiology and recurrence of LGGs. DISCUSSION: This scoping review will be the first to evaluate the current landscape of LGG management and outcomes in Africa, highlighting pertinent themes that may be used to guide further research as well as health system strengthening efforts by policymakers and stakeholders. SCOPING REVIEW REGISTRATION: The protocol has been registered on the Open Science Framework (OSF; registration link: https://doi.org/10.17605/OSF.IO/E732G). HIGHLIGHTS: LGGs account for 17% to 22% of total brain tumours and have a median survival time between 5.6 and 13.3 years.Despite many recent advancements in the management of LGGs, there is a paucity in the data within the African landscape.This scoping review will be the first to evaluate the current landscape of LGG management and outcomes in Africa, highlighting pertinent themes that may be used to guide further research and policymaking efforts.

RESUMO

INTRODUCTION: Despite recent advancements in the management of low-grade gliomas (LGGs), there is a paucity in the data within the African landscape. We aim to evaluate the epidemiology, management, and outcomes of LGGs in Africa. METHODS: Systematic searches of MEDLINE, Embase and African Journals Online were performed from database inception to January 27, 2021, for studies reporting on LGGs in Africa. Pooled statistics were calculated using measures of central tendency and spread. RESULTS: 554 unique studies were identified, of which 25 were included. The mean age of patients was 15.7 years (95% confidence interval (CI): 11.8-19.6) and 56.4% were male (95% CI: 55.6-62.6%). Most patients had solitary lesions (86.0%, 95% CI: 82.8-89.1%) located in the infratentorial region (71.6%, 95% CI: 66.1-77.1%). Most LGGs received histopathological diagnosis (71.7%, 95% CI: 69.2-74.2%) and astrocytoma was the most common type (81.1%, 95% CI: 78.5-83.7%). 37 patients had awake surgery (3.1%, 95% CI: 2.0-4.0%) and there were no reports of molecular pathology testing, intraoperative neuroimaging, or 5-aminolevulinic acid. Gross total resection was achieved in 74.8% (95% CI: 69.6-80.0%) and there was a recurrence rate of 1.7% (95% CI: 0.9-2.4%), with a mean follow-up of 19.4 months (95% CI: 6.9-31.9). CONCLUSION: LGGs are underreported in Africa. We found a lag in the uptake of techniques established in high-income countries for improving patient outcomes. Future efforts will require further training and funding in molecular pathology testing and advanced surgical adjuncts.

RESUMO

Introduction: Although the past decade has seen a substantial increase in African neurosurgeons' academic productivity, productivity remains low compared to their colleagues from other regions. Aspiring neurosurgeons can contribute to the academic neurosurgery workforce by taking care of less technical and time-consuming research tasks. Fortunately, global neurosurgery institutions have also made efforts to increase research exposure and scholarly output in academic global neurosurgery. The Association of Future African Neurosurgeons (AFAN) created a research incubator for aspiring academic global neurosurgeons in Africa to provide enrollees with mentorship, skills, and experience. This study assesses and reports the activities and results of the research incubator. Methods: Aspiring academic global neurosurgeons were enrolled in the AFAN Research Incubator Program (ARIP), whose primary objective was to provide enrollees with foundational skills in all aspects of the research cycle. ARIP enrollees participated in didactic and practical activities with the aim of publishing ≥1 article and presenting ≥1 abstracts at international conferences in one year. Results: Fifteen AFAN members aged 25.0 ± 3.0 years enrolled in ARIP: 7 (46.7%) medical students, 4 (26.7%) general practitioners, and 4 (26.7%) residents. Eleven (73.3%) were male, 6 (40.0%) were from Cameroon and 6 (40.0%) had no previous research experience. Two (13.3%) enrollees dropped out. ARIP enrollees published a total of 28 articles, and enrollees published a median of 1.0 (IQR = 2) first-author articles on neurosurgical system strengthening. Additionally, ARIP enrollees presented 20 abstracts with a median of one abstract (IQR = 3.0). Conclusion: South-South research collaborations like ARIP can contribute to improving global neurosurgery research capacity and output. These collaborations can set up the foundations for robust research in low- and middle-income countries.

RESUMO

BACKGROUND: Although nontraumatic diseases affect fewer people than traumatic neurosurgical diseases, they require expertise more often. The authors sought to understand the barriers to nontraumatic neurosurgical diseases (NTNSDs) in a country with limited access to neurosurgical care. METHODS: This cross-sectional study with retrospective data collection was carried out in 2 Cameroonian reference hospitals for a year. Multiple imputations were used to generate data for the missing variables-death and discharge with sequelae. Bivariate relationships were evaluated using the chi-square and Mann-Whitney U tests. Odds ratios were equally calculated, and the results were considered significant for a P value <0.05. RESULTS: NTNSDs represented 44.1% of neurosurgical activity. Our study included 177 patients with a mean age of 43.7 ± 21.2 years. More than half (53.1%) were female, 78% lived in a different region from that of the neurosurgical center, 18.1% had health insurance, 39.5% were referrals, and the mean symptom-to-admission delay was 409.0 ± 1301.7 days. Most (87%) of the patients had undergone at least 1 of the diagnostic examinations prescribed to them. Men (P = 0.029) and rural dwellers (P = 0.017) had shorter symptom-to-admission delays than women and urban dwellers, respectively. The mean length of stay was 18.2 ± 13.4, and 80.8% of patients were treated surgically. Thirty-one (17.5%) patients died in the hospital: 9 were treated surgically, and 22 were treated conservatively or expectantly. CONCLUSIONS: Patients with NTNSD present at the definitive care facilities late. This delay is attributable to financial and geographic barriers.

RESUMO

BACKGROUND: Traumatic brain injury (TBI) is the most common neurosurgical condition globally. In Cameroon, there are 572 cases of TBI per 100,000 people, but <40% of Cameroonians live within 4 hours of a neurosurgical facility. We sought to understand the clinical outcomes at a neurosurgical center in Central Cameroon. METHODS: This cross-sectional study was conducted at the largest neurosurgical center of Cameroon, the Yaounde Central Hospital. Data included 100 consecutive patients undergoing an intervention 72 hours after their injury from February 1, 2015 to February 1, 2019. Patients with missing data or undergoing surgery >72 hours after injury were excluded. Analyses of covariance were performed, and a P value >0.05 was considered significant. A Kaplan-Meier survival curve was computed. RESULTS: The patients had a mean age of 31.3 ± 17.4 years, with a male predominance of 91.0%, and the principal mechanism of injury was road traffic accidents (68.0%). Only 11% arrived via ambulance, and 36.0% were admitted <3 hours after the traumatic event. The postoperative mortality was 15.0%, mean survival was 25.0 postoperative days (95% confidence interval, 23.42-26.52), and the mean Glasgow Outcome Scale score at 28 days was 3.9 ± 1.4. CONCLUSIONS: Most patients with TBI undergoing neurosurgery 72 hours after injury in Cameroon arrive at the hospital late and have a high mortality risk during the first postoperative week. Investments in prehospital care should be made to improve surgical outcomes.
