Health systems strengthening, dissemination, and implementation science in Africa: quo vadis?

Implementing health-system strengthening policies remains a challenge in Africa. Past successes, predictable but unanticipated flaws, underutilization of health services, traditional medicine, global inequity and poor practice by local stakeholders are some of the reasons many African countries have made little progress towards attaining global health goals. As a result, Africa has the highest disease burden despite multiple efforts from the global health community. These raise the question: what has to change so that health systems strengthening efforts in Africa are successful

Needs of Young African Neurosurgeons and Residents: A Cross-Sectional Study

Introduction: Africa has many untreated neurosurgical cases due to limited access to safe, affordable, and timely care. In this study, we surveyed young African neurosurgeons and trainees to identify challenges to training and practice. Methods: African trainees and residents were surveyed online by the Young Neurosurgeons Forum from April 25th to November 30th, 2018. The survey link was distributed via social media platforms and through professional society mailing lists. Univariate and bivariate data analyses were run and a P-value \u3c 0.05 was considered to be statistically significant. Results: 112 respondents from 20 countries participated in this study. 98 (87.5%) were male, 63 (56.3%) were from sub-Saharan Africa, and 52 (46.4%) were residents. 39 (34.8%) had regular journal club sessions at their hospital, 100 (89.3%) did not have access to cadaver dissection labs, and 62 (55.4%) had never attended a WFNS-endorsed conference. 67.0% of respondents reported limited research opportunities and 58.9% reported limited education opportunities. Lack of mentorship (P = 0.023, Phi = 0.26), lack of access to journals (P = 0.002, Phi = 0.332), and limited access to conferences (P = 0.019, Phi = 0.369) were associated with the country income category. Conclusion: This survey identified barriers to education, research, and practice among African trainees and young neurosurgeons. The findings of this study should inform future initiatives aimed at reducing the barriers faced by this group

Prevalence of spine surgery navigation techniques and availability in Africa: A cross-sectional study

Background: Africa has a large burden of spine pathology but has limited and insufficient infrastructure to manage these spine disorders. Therefore, we conducted this e-survey to assess the prevalence and identify the determinants of the availability of spine surgery navigation techniques in Africa. Materials and methods: A two-part questionnaire was disseminated amongst African neurological and orthopedic surgery consultants and trainees from January 24 to February 23, 2021. The Chi-Square, Fisher Exact, and Kruskal-Wallis tests were used to evaluate bivariable relationships, and a p-value \u3c0.05 was considered statistically significant. Results: We had 113 respondents from all regions of Africa. Most (86.7 %) participants who practiced or trained in public centers and centers had an annual median spine case surgery volume of 200 (IQR = 190) interventions. Fluoroscopy was the most prevalent spine surgery navigation technique (96.5 %), followed by freehand (55.8 %), stereotactic without intraoperative CT scan (31.9 %), robotic with intraoperative CT scan (29.2 %), stereotactic with intraoperative CT scan (8.8 %), and robotic without intraoperative CT scan (6.2 %). Cost of equipment (94.7 %), lack of trained staff to service (63.7 %), or run the equipment (60.2 %) were the most common barriers to the availability of spine instrumentation navigation. In addition, there were significant regional differences in access to trained staff to run and service the equipment (P = 0.001). Conclusion: There is a need to increase access to more advanced navigation techniques, and we identified the determinants of availability

Management and outcomes of traumatic paediatric spinal cord injuries in low- and middle-income countries: a scoping review protocol

Background Traumatic spinal cord injury (TSCI) accounts for a significant proportion of deaths and disability worldwide and this is largely concentrated in low- and middle-income countries (LMICs). Though rare, a subset of TSCIs occurs in children, which can lead to long-term comorbidities if not managed within the optimal time frame. However, the lack of pre-hospital care, infrastructure and specialist manpower in LMICs may pose a challenge for health practitioners to provide quality and consistent standard of care to the children. The variety in practice and lack of clarity on management and outcomes of TSCIs in LMICs necessitates an evaluation of the literature. This scoping review protocol outlines how the authors will address the said topic of interest. Methods MEDLINE, Embase and Global Index Medicus will be searched from database inception to date in order to identify the relevant studies. Paediatric patients (ages 18 or below) with a TSCI managed in an LMIC country will be included. Surgical and conservative management of TSCIs will be considered. Original research, reviews, commentaries, editorials and case reports will be included. Results Primary outcomes will include TSCI epidemiology, presentation, management, morbidity, mortality and long-term complications. Secondary outcomes will include delays in receiving care. Discussion This scoping review will be the first to evaluate the current landscape of paediatric TSCI management and outcomes in LMICs, highlighting pertinent themes that may be used to guide further research as well as health system strengthening efforts by policymakers and stakeholders

Management and outcomes of sellar, suprasellar and parasellar masses in low- and middle-income countries: a scoping review protocol

Sellar, suprasellar or parasellar masses refer to space-occupying lesions that arise from the area surrounding the pituitary gland and many other vital structures, which can impact quality of life if damaged. Therefore, optimal management by a multidisciplinary team, which includes neurosurgeons, would be required to ensure that patients receive timely intervention to prevent long-term co-morbidities. The landscape of management of these masses in high-income countries are well described in the literature, however, there is a lack of clarity in the counterpart low- and middle-income countries, thus necessitating an evaluation of the literature. This protocol outlines how we will conduct our scoping review on the topic of interest. MEDLINE, Embase, Global Index Medicus and African Journals Online will be searched from year 2000 to date in order to identify the relevant studies. Patients with a sellar, suprasellar or parasellar masses managed in an LMIC will be included. Surgical, medical and conservative management of the relevant masses will be considered. Articles in English and French will be included. Primary outcome will describe the management of sellar, suprasellar, or parasellar masses in LMICs. Secondary outcomes will include describing the epidemiology, presentation and outcomes of patients with sellar, suprasellar or parasellar masses. This scoping review will be the first to evaluate the current landscape of the management and outcomes of sellar, suprasellar and parasellar masses in LMICs, highlighting important themes that may be used to guide further research as well as health system strengthening efforts by policymakers, governments and stakeholders

Outcomes of single brain metastasis treated with gamma knife stereotaxic radiosurgery(GKSR). Our experience on 103 cases

Background: Brain metastases (BM) occur in the natural course of malignant tumors in 18–40% of cases. Their management has changed considerably over the past decade thanks to the advent of Gamma knife Stereotactic Radiosurgery (GKSR). Objective: We report our experience on Single Brain metastasis treated with (GKSR). Methods: Patients treated by Gamma Knife stereotaxic radiosurgery (GKSR) in our institution between 2009 and 2021 for Single BM were recorded retrospectively. Results: A total of 103 patients (n = 52; 50.5% females) were included, with a mean age of 56.33 ± 11.33. Breast (n = 39, 37.9%) and lung (n = 36, 35%) were the common original location for the primary tumors. GKSR alone without prior surgery, radiotherapy, or chemotherapy was achieved in 81.5% (n = 84). Thirteen patients (15.1%) progressed in BM volume while finding the appearance of de novo BM in 5 (5.8%) patients. The median percentage of tumor control after radiosurgery treatment was 70% (IQR: 65–78) and only 26.2% (n = 27) of patients had > 80% tumor control and stability over the median follow-up time of 5 (95% CI, 4–6) months. We found only two cases of radionecrosis (1.9%). The median survival time was 5.21 (IQR, 3–8) months. Retreatment, recursive partitioning analysis (RPA) class, and tumor stability influenced the overall survival of BM respectively (Hazard Ratio adjust (HRa)= 5.610,p = 0.045; HRa= 6.133,p = 0.031; HRa= 22.463, p = 0.036). Conclusion: Stereotaxic Radiosurgery provides good results in terms of Overall survival with fewer neurocognitive disorders.RPA class and tumor control (stability) influenced the overall survival of single BM

Management and outcomes of traumatic paediatric spinal cord injuries in low- and middle-income countries: A scoping review

Background Traumatic spinal cord injury (TSCI) is a subset of neurotrauma, which is a significant contributor to global trauma mortality and morbidity in children. The management and outcomes of paediatric TSCI in low-and-middle income countries (LMICs) is unknown. We conducted a scoping review to characterise the methods of management and outcomes of TSCI in LMICs. Methods MEDLINE, EMBASE, and Global Index Medicus were searched from database inception to February 15, 2021. Studies reporting management or outcomes of paediatric TSCI in LMICs were included. Pooled statistics were calculated using measures of central tendency and spread. Results A total of 1171 studies were identified, of which, 5 were included. A total of 212 patients were included in our review with age of participants ranging from 2.5 to 18 years old (mean = 15.4 years). Most patients were male (n=162, 76.4%). The commonest cited cause of injury were falls (n=104/212, 49.1%). The most common level of injury was cervical (n=83, 39.2%). The majority of patients underwent surgery (n=134/212, 63.2%). The extent of injury was quantified and classified using the ASIA chart in only one paper. Long-term management data was not present in any of the included studies. Conclusion There is a scarcity of published studies reporting the management and outcome of paediatric TSCI in LMICs. The paucity of studies in this domain provides insufficient data to be compared, reducing the ability to draw a strong conclusion. This hinders the development of guidelines to inform best practice
