Abstract
OBJECTIVE This study investigates the scope, trends, and challenges of neurosurgical research in Nigeria since inception of the specialty in 1962. METHODS A bibliometric review of the neurosurgical literature from Nigeria was performed. Variables extracted included year and journal of publication, article topic, article type, research type, study design, article focus area, and limitations. Descriptive and quantitative analyses were performed for all variables. Trends of research publications were described in three periods: pioneering (1962-1981), recession (1982-2001), and resurgent (2002-2021). RESULTS Of the 1023 included articles, 10.0% were published in the pioneering period, 9.2% in the recession period, and 80.8% in the resurgent period. Papers were predominantly published in World Neurosurgery (4.5%) and Nigerian Journal of Clinical Practice (4.0%). A total of 79.9% of the 4618 authors were from Nigerian institutions; 86.3% of the articles covered clinical research and were mainly focused on service delivery and epidemiology (89.9%). The most prominent topics were traumatic brain injury (25.8%) and central nervous system malignancy (21.4%). Only 4.4% of the publications received funding, mostly from agencies in the United States (31.7%). Barriers to neurosurgical research included lack of clinical databases (18.0%), increasing burden of disease (12.5%), and diagnostic challenges (12.4%). CONCLUSIONS Neurosurgical research in Nigeria continues to grow due to increased training, workforce, and infrastructural improvements. Addressing the major challenges through establishment of research databases, development of evidence-based management guidelines, and increasing research training, funding and opportunities can increase research capacity in Nigeria.

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.

Abstract
OBJECTIVE Despite 6 decades of existence, neurosurgery is still in the developing stages in Nigeria. In this era of collaborative health system capacity-building in low- and middle-income countries, this article reviews past efforts and future prospects for collaborative neurosurgical development in Nigeria. METHODS A bibliometric review of the Nigerian neurosurgical literature and data from a structured survey of Nigerian neurosurgeons and residents provided details of current local and international collaborations for neurosurgical research, service delivery, training, and capacity building. These were analyzed to provide an overview of the role of collaborations in sustainable neurosurgical development in Nigeria and to recommend approaches to enhance neurosurgical capacity. RESULTS In 1023 peer-reviewed neurosurgery publications from Nigeria, there were 4618 authors with 3688 from 98 Nigerian institutions and 930 from 296 foreign institutions in 70 countries. While there were significant research collaborations amongst Nigerian institutions, the most common were with institutions in the US, United Kingdom, and Cameroon. From the survey, 62 of 149 respondents (41.6%) from 32 health facilities noted their institution's involvement in capacity-building neurosurgical collaborations. These collaborations involved 22 Nigerian institutions and 13 foreign institutions in 9 countries and were mostly for training and workforce development (78.1%), and research and data management (59.4%). The majority of foreign institutions were from the US and United Kingdom. CONCLUSIONS Current and previous neurosurgical collaborations have led to sustainable progress in Nigeria. Further local, regional, and international collaborations would enhance the capacity to address the needs and challenges affecting neurosurgery in Nigeria.

Abstract
OBJECTIVE Neurotrauma is a significant cause of morbidity and mortality in Nigeria. We conducted this systematic review to generate nationally generalizable reference data for the country. METHODS Four research databases and gray literature sources were electronically searched. Risk of bias was assessed using the Risk of Bias in Non-Randomized Studies of Interventions and Cochrane's risk of bias tools. Descriptive analysis, narrative synthesis, and statistical analysis (via paired t-tests and χ2 independence tests) were performed on relevant article metrics (α = 0.05). RESULTS We identified a cohort of 45,763 patients from 254 articles. The overall risk of bias was moderate to high. Most articles employed retrospective cohort study designs (37.4%) and were published during the last 2 decades (81.89%). The cohort's average age was 32.5 years (standard deviation, 20.2) with a gender split of ∼3 males per female. Almost 90% of subjects were diagnosed with traumatic brain injury, with road traffic accidents (68.6%) being the greatest cause. Altered consciousness (48.4%) was the most commonly reported clinical feature. Computed tomography (53.5%) was the most commonly used imaging modality, with skull (25.7%) and vertebral fracture (14.1%) being the most common radiological findings for traumatic brain injury and traumatic spinal injury, respectively. Two-thirds of patients were treated nonoperatively. Outcomes were favorable in 63.7% of traumatic brain injury patients, but in only 20.9% of traumatic spinal injury patients. Pressure sores, infection, and motor deficits were the most commonly reported complications in the latter. CONCLUSIONS This systematic review and pooled analysis demonstrate the significant burden of neurotrauma across Nigeria.

Abstract
OBJECTIVE Spinal pathologies are prevalent in Nigeria, though epidemiological data remains sparse. This systematic review used pooled patient-level data from across the country to generate a standardized epidemiological reference. METHODS Four research databases and gray literature sources were searched. Risk of bias assessment was conducted using Risk of Bias in Non-Randomised Studies - of Interventions and Cochrane's risk of bias tool. We descriptively analyzed all article metrics and statistically analyzed relevant data variables via paired t-test and χ2 independence tests (α = 0.05). RESULTS One hundred twenty-seven articles, comprising a patient cohort of 8425 patients, were analyzed. Most were retrospective cohort studies (46.5%) and case reports/series (31.5%), with an overall moderate-high risk of bias. Most studies were published in the last 20 years. Most patients were male (∼2.5 males per female), with an average age of 43.2 years (±16.4). Clinical diagnoses spanned the breadth of spinal neurosurgery. Approximately 45.0% of patients had complete spinal impairment. Pain (41.7%) was the most reported presenting feature. X-ray (45.1%) was the most common investigation used. Intervertebral disc herniation (18.9%) was the most prevalent imaging finding on MRI. Most patients were managed nonoperatively (57.8%), with a favorable outcome in 27.4% of patients. Posttreatment complications included pressure sores, infection, and motor deficits. CONCLUSIONS This systematic review and pooled analysis provide an epidemiological overview of spinal neurosurgery in Nigeria over the last 60 years and serves as a useful reference to direct future global research in this arena.

Abstract
OBJECTIVE Vascular neurosurgery has developed significantly in Nigeria, but its burden and challenges remain unclear. This study systematically reviewed vascular neurosurgical literature from Nigeria. METHODS Four research databases and gray literature sources were searched from 1962-2021. ROBINS-I tool was used to assess risk of bias. Descriptive, narrative, and statistical analyses were conducted on all variables. Where appropriate, paired t-tests and Chi-squared independence tests were used (α = 0.05). RESULTS 56 articles were included and 3203 patients pooled for analysis. Risk of bias was moderate-high. Most articles were published over the last 20 years with retrospective cohort studies and case reports being the most common study designs. The cohort had a relatively even gender split and an average age of 49 years (±22). Cerebrovascular accidents accounted for over 85% of diagnoses, with most etiologies being traumatic. Headache and motor deficit were the most prevalent clinical features. X-ray and carotid angiography were the most commonly reported imaging modalities, closely followed by computed tomography (CT) and CT angiography. The top two radiological diagnoses were ischemic cerebrovascular disease and intracerebral hematoma. Aneurysmal clipping and hematoma evacuation were the most commonly reported treatment modalities. Outcome at last follow-up was favorable in 48%. The mortality rate was 6%. Post-treatment complications included chest infection and rebleeding. CONCLUSIONS This study illustrates the epidemiological burden of neurovascular pathology (based on the available data in published literature) in Nigeria, and raises awareness amongst service providers and researchers of the attendant challenges and epochal trends seen within vascular neurosurgery in Nigeria.

Abstract
OBJECTIVE Access to neuro-oncologic care in Nigeria has grown exponentially since the first reported cases in the mid-1960s. In this systematic review and pooled analysis, we characterize the growth of neurosurgical oncology in Nigeria and build a reference paper to direct efforts to expand this field. METHODS We performed an initial literature search of several article databases and gray literature sources. We included and subsequently screened articles published between 1962 and 2021. Several variables were extracted from each study, including the affiliated hospital, the number of patients treated, patient sex, tumor pathology, the types of imaging modalities used for diagnosis, and the interventions used for each individual. Change in these variables was assessed using Chi-squared independence tests and univariate linear regression when appropriate. RESULTS A total of 147 studies were identified, corresponding to 5,760 patients. Over 4000 cases were reported in the past 2 decades from 21 different Nigerian institutions. The types of tumors reported have increased over time, with increasingly more patients being evaluated via computed tomography (CT) and magnetic resonance imaging (MRI). There is also a prevalent use of radiotherapy, though chemotherapy remains an underreported treatment modality. CONCLUSIONS This study highlights key trends regarding the prevalence and management of neuro-oncologic pathologies within Nigeria. Further studies are needed to continue to learn and guide the future growth of this field in Nigeria.

Abstract
Abstract
Background
Hyponatremia serves as a well established predictor of mortality for advanced heart failure (1). The aim of this study is to reassess the association between hyponatremia and in-hospital outcomes in patients with acute decompensated heart failure (ADHF) by using a nationally representative sample.
Methods
We queried the National Inpatient Sample (NIS) database collected between 2016 and 2018 to identify patients with a primary diagnosis of HF and stratified the cohort on the basis of presence or absence of hyponatremia. The outcomes of interest included in-hospital mortality, common associated complications and usage of circulatory support.
Results
Among 727,629 hospital admissions for HF, 72,824 (10%) of them had an additional diagnosis of hyponatremia. The hyponatremia cohort appeared similar in age and had similar rates of Charlson comorbidity index greater than 4 (71 years vs 72 years and 33% vs 35%, respectively) compared to the non-hyponatremia cohort. The comorbidities more prevalent in patients with hyponatremia included: hypothyroidism (17% vs 21%, p<0.001), liver disease (4% vs 11%, p<0.001) and anemia (31% vs 42, p<0.001). By contrast, dyslipidemia, chronic obstructive pulmonary disease, chronic kidney disease, hypertension, diabetes mellitus, obesity, smoking status and supplemental oxygen use were comparable in both groups. ADHF patients with hyponatremia did not have higher odds of in-hospital mortality (aOR: 1.08, 95% CI: 0.98–1.19, p=0.138) when adjusted for comorbidities. Nevertheless, patients with hyponatremia had an adjusted increase in mean hospital charges of 14,731 US$ (95% CI: 11065–18397, p<0.001), length of stay by 2.6 days (95% CI: 2.5–2.8, p<0.001), usage of intra-aortic balloon pump (aOR: 1.97, 95% CI: 1.50–2.59, p<0.001) and left ventricular assist device (aOR: 2.21, 95% CI: 1.639–2.98, p<0.001), and higher incidence of acute renal failure (aOR: 1.13, 95% CI: 1.08–1.189, p<0.001) and cardiogenic shock (aOR: 1.58, 95% CI: 1.42–1.76, p<0.001) in comparison to patients without hyponatremia.
Conclusion
Multiple clinical variables excluded in the NIS dataset could have impacted the primary outcome. Clinicians who observe hyponatremia in ADHF patients should stay wary of potential side effects and maintain a low threshold to escalate care.
