Abstract
BACKGROUND There is evidence that individuals of African ancestry, particularly those residing in Africa, suffer from an unfortunate amount of under-representation in cancer research worldwide. AIM We aimed to analyze current research output and potentially predict future trends in neuro-oncological research in Africa. Investigating deficits in the field will assist in identifying top-performing countries, which ones face challenges, and how to solve them. Therefore, targeted interventions can be applied to overcome these challenges. METHODS We conducted a systematic computer-based search on the following databases (PubMed, Scopus, Web of Science, and Embase) for research articles related to the neuro-oncological field in Africa. We aimed to retrieve any article published in the period between 1 January 2000 and 10 January 2023. RESULTS We included 200 eligible articles in our study. The output of neuro-oncological research has been increasing over the past two decades, peaking in 2019. Among the included articles, clinical practice issues constituted the majority (80%), while public health-related topics accounted for 20% of the publications. Regarding the type of neurological tumor, neuroblastoma was the most common, with 26 articles (13%), meningioma with 21 (10.5%), and glioma with 16 articles (8%). CONCLUSION The interest in African neuro-oncological research is increasing. Hence, there is a need for ongoing efforts to address issues with clinical practice and public health related to neurological tumors in the continent. Future studies should concentrate on filling in knowledge gaps and investigating novel methods for neuro-oncological conditions that affect African populations in terms of prevention, diagnosis, treatment, and management strategies.

Abstract
INTRODUCTION Growth hormone deficiency occurs when the pituitary gland does not produce enough growth hormone. Norditropin®, a recombinant human growth hormone, and Sogroya®, an albumin-binding growth hormone derivative, are prescribed for patients with growth hormone deficiency. This systematic review assesses the efficacy, safety, and patient satisfaction associated with Norditropin and Sogroya. METHODS We systematically searched PubMed, Web of Science, and Scopus databases to identify eligible comparative studies. All studies published until June 2023 were included in our analysis. Our outcomes for children included height velocity and height velocity standard deviation score. In contrast, adult outcomes included adverse events, insulin-like growth factor 1-standard deviation score (IGF-1 SDS), and the Treatment Satisfaction Questionnaire for Medication-9 (TSQM-9). Results are reported as odds ratio (OR) and mean difference (MD) with a 95% confidence interval (95% CI). RESULTS Ten studies involving 1058 participants (665 children and 393 adults) were included in the meta-analysis. In children, Norditropin at doses of 0.034 and 0.067 mg/kg/day was compared to Sogroya at doses of 0.04, 0.08, 0.16, and 0.24 mg/kg/week. The results showed that 0.034 mg/kg/day Norditropin had a favorable impact on height velocity (MD -2.01, 95% CI -3.7 to -2.12, p < 0.00001) and height velocity standard deviation score (Mean Difference -3.61, 95% CI -5.06 to -2.16, p < 0.00001) when compared to Sogroya 0.04 mg/kg/day. Other doses showed comparable results. In adults, the only significant side effect noted was rash, which favored Sogroya (OR 0.1, 95% CI 0.04-0.27, p < 0.00001). Additionally, IGF-1 SDS was significantly higher in the Sogroya group than in the Norditropin group (MD 0.25, 95% CI 0.02-0.48, p = 0.03). Furthermore, the overall score of the TSQM-9 questionnaire, which includes three domains: convenience, effectiveness, and satisfaction, was significantly higher in the Sogroya group compared to the Norditropin group (OR 6.36, 95% CI 3.92-8.8, p < 0.00001). CONCLUSION Norditropin and Sogroya showed comparable efficacy and safety profiles, except for the prevalence of rash in the Norditropin group, and Sogroya has higher satisfaction among adults. More high-quality studies with more patients are required to confirm these results.

Abstract
BACKGROUND Despite advancements in the management of HIV infection, the factors contributing to stroke development among HIV-positive individuals remain unclear. This systematic review and meta-analysis aim to identify and evaluate the relative risk factors associated with stroke susceptibility in the HIV population. METHODS A comprehensive search was conducted in PubMed, Scopus, and Web of Science databases to identify studies investigating the risk of stroke development in HIV patients and assessing the role of different risk factors, including hypertension, diabetes, dyslipidemia, smoking, sex, and race. The quality assessment of case-control studies was conducted using the Newcastle-Ottawa Scale, whereas cohort studies were assessed using the National Institute of Health tool. Meta-analyses were performed using a random-effects model to determine pooled hazard ratios (HRs) or odds ratios (ORs) with 95% confidence intervals (CIs). RESULTS A total of 18 observational studies involving 116,184 HIV-positive and 3,184,245 HIV-negative patients were included. HIV-positive patients exhibited a significantly higher risk of stroke compared with HIV-negative patients [OR (95% CI): 1.31 (1.20 to 1.44)]. Subgroup analyses revealed increased risks for both ischemic stroke [OR (95% CI): 1.32 (1.19 to 1.46)] and hemorrhagic stroke [OR (95% CI): 1.31 (1.09 to 1.56)]. Pooled adjusted HRs showed a significant association between stroke and HIV positivity (HR: 1.37, 95% CI: 1.22 to 1.54). Among HIV-positive patients with stroke, hypertension [OR (95% CI): 3.5 (1.42 to 8.65)], diabetes [OR (95% CI): 5 (2.12 to 11.95)], hyperlipidemia, smoking, male gender, and black race were associated with an increased risk. DISCUSSION Our study revealed a significant increased risk of stroke development among people with HIV. A multitude of factors, encompassing sociodemographic characteristics, racial background, underlying health conditions, and personal behaviors, significantly elevate the risk of stroke in individuals living with HIV. The use of observational studies introduces inherent limitations, and further investigations are necessary to explore the underlying mechanisms of stroke in people with HIV for potential treatment strategies. CONCLUSION HIV patients face a higher risk of stroke development, either ischemic and hemorrhagic strokes. Hypertension, diabetes, hyperlipidemia, smoking, male gender, and black race were identified as significant risk factors. Early identification and management of these risk factors are crucial in reducing stroke incidence among patients living with HIV.

Abstract
OBJECTIVES To compare the safety and efficacy of Dual Antiplatelet Therapy (DAPT) and Intravenous (IV) Tissue Plasminogen Activator (t-PA) in minor Acute Ischemic Stroke (AIS). MATERIALS AND METHODS Following Cochrane and PRISMA guidelines, we analyzed observational studies and clinical trials comparing DAPT and IV t-PA in patients with minor AIS. Databases included PubMed, Scopus, and Web of Science. Data extraction included study characteristics, patient demographics, and analyzed outcomes. RevMan 5.3 and OpenMetaAnalyst 2021 were used to analyze the data and assess heterogeneity, respectively. The risk of bias was determined using RoB 2.0 and the Newcastle-Ottawa scale. RESULTS This meta-analysis included five studies with 3,978 DAPT-treated patients and 2,224 IV t-PA-treated patients. We found no significant differences in achieving modified Rankin scale (mRS) scores of 0-1 (OR 1.11, 95 % CI: 0.79, 1.55, p = 0.56) and 0-2 (OR 0.90, 95 % CI: 0.61, 1.31, p = 0.57), as well as combined mRS scores (OR 1.05, 95 % CI: 0.82, 1.34, p = 0.72). Similarly, there were no significant disparities between the two treatment groups in NIHSS score change from baseline (MD 0.32, 95 % CI: -0.35, 0.98, p = 0.35) and in mortality rates (OR 0.87, 95 % CI: 0.26, 2.93, p = 0.83). Notably, in comparison to the IV t-PA group, the DAPT group exhibited a significantly lower incidence of bleeding (OR 0.31, 95 % CI: 0.14, 0.69, p = 0.004) and symptomatic intracranial hemorrhage (sICH) (OR 0.10, 95 % CI: 0.04, 0.26, p < 0.00001). CONCLUSIONS Our meta-analysis found no significant differences in efficacy between DAPT and IV t-PA. However, DAPT demonstrated a significantly lower risk of sICH and bleeding compared with IV t-PA.

Abstract
INTRODUCTION Rett syndrome is a rare genetic neurodevelopmental disorder that predominantly impacts females. It presents with loss of acquired skills, impaired communication, and stereotypic hand movements. Given the limited treatment options for Rett syndrome, there is a dire need for effective interventions. OBJECTIVE To evaluate the safety and efficacy of trofinetide in Randomized Controlled Trials (RCTs) that report on Rett syndrome patients. METHODS We identified 109 articles from four databases (Scopus, PubMed, Web of Science, and Cochrane CENTRAL). After removing the duplicates, we narrowed them down to 59 articles for further assessment. We included RCTs that evaluated the efficacy and safety of trofinetide in patients with Rett syndrome. Three studies were eligible for inclusion. Two independent reviewers evaluated the identified studies' titles, abstracts, and full texts, extracting pertinent data. We assessed the quality of the studies using the Cochrane Risk of Bias (RoB) 2.0 tool. We then conducted a meta-analysis using the fixed effects model in the case of insignificant heterogeneity; otherwise, we used the random effects model. Based on the nature of the outcome, we analyzed the mean difference or the odds ratio. Analysis was conducted using RevMan version 5.3. RESULTS Among the analyzed outcomes in 181 patients in the trofinetide group and 134 patients in the placebo group, significant improvement in Rett Syndrome Behavior Questionnaire (RSBQ) scores was observed at 200 mg dosage (overall mean difference: -3.53, p = 0.001). Clinical Global Impression-Improvement (CGI-I) scores improved considerably at 200 mg dosage (overall mean difference: -0.34, p < 0.0001). No substantial changes were observed in Motor Behavioral Assessment (MBA) or Top 3 Caregiver Concerns. We evaluated Treatment Emergent Adverse Events (TEAEs) across the various dosages and noted significant associations with diarrhea (200 mg), vomiting (200 mg), and irritability (200 mg). However, we did not find a significant association between any of the dosages and the incidence of decreased appetite. CONCLUSION Trofinetide demonstrated potential in improving RSBQ and CGI-I scores at 200 mg dosage. Although no substantial changes were found in MBA and top 3 caregiver concerns. Adverse events were linked to specific dosages.

Abstract
PURPOSE To investigate the occurrence of chorioretinopathy post-COVID-19, emphasizing demographic characteristics, medication history, clinical presentation, diagnostic evaluation, and treatment approaches, with a specific focus on the role of corticosteroid use. METHODS Our protocol was registered prospectively on PROSPERO (CRD42023457712). A systematic search of databases (PubMed, Cochrane, WOS, Scopus) from November 2020 to August 2023 were performed to identify any original research reporting chorioretinopathy in COVID-19 patients. Data extraction included patient demographics, COVID-19 timeline, medication history, symptoms, diagnostic tests, and treatment outcomes. We used Joanna Briggs Institute (JBI) critical appraisal tool to assess the quality of our included studies. RESULTS We identified seven case reports and two case series including 10 patients, six females and four males (mean age 36.5 years), who exhibited chorioretinopathy after COVID-19. Onset varied from 6 days to three months post-infection (average = 24.3 days). Seven patients (70%) had a history of corticosteroid use during COVID-19 treatment. Symptoms included visual loss, blurred vision, and deterioration. Diagnostic assessments revealed central serous chorioretinopathy in seven patients (70%) and punctate inner choroidopathy in two (20%). Treatment approaches varied, with corticosteroid discontinuation leading to symptom improvement, while two patients were treated with corticosteroids. Five patients who discontinued corticosteroids were reported to have improvement in visual acuity, two of them changed to 20/25 after being 20/40, two changed to 6/6, and one changed to 20/20, while the visual acuity in the sixth patient was not reported. Regarding the two patients who were treated with corticosteroids, visual acuity was reported in one case only and it improved to 20/20. CONCLUSION This systematic review states the prevalence and potential association between chorioretinopathy, and corticosteroid use in the context of COVID-19. This relation is still unclear because of the relief of symptoms in some cases after corticosteroid discontinuation, while two other cases were treated with corticosteroids and their symptoms improved.

Abstract
BACKGROUND Head and neck cancer (HNC) encompasses malignant tumors in areas like the oral cavity, pharynx, and larynx. This analysis identifies strengths and deficiencies in HNC research, aiming to improve published papers' quality, quantity, and diversity. It also encourages more participation from oncologists, particularly in Egypt, to bridge the gap with Western healthcare standards. METHODS A systematic search was conducted in databases including PubMed, Scopus, Web of Science, and Embase. The goal was to gather research articles on HNC in Egypt published from January 1, 2000, to December 31, 2022. RESULTS From 2150 articles, 1329 were screened by title and abstract, leading to 193 for full-text review. Finally, 174 articles were included in the final analysis. 2020 saw the highest number of publications. The majority were primary research articles, with randomized controlled trials being prevalent. Most studies were clinical, focusing on radiotherapy, and involved adult patients, emphasizing service delivery. Publications were predominantly in non-Egyptian journals, with the Egyptian Journal of Radiology and Nuclear Medicine being the most frequent. Research was mainly conducted by Egyptian authors and at Cairo University. CONCLUSION The growing prevalence of HNC in Egypt underscores the need for more comprehensive research on its various aspects, including etiology, risk factors, and prevention. There's a call for increased research outputs at different Egyptian universities, multicenter studies, and international collaborations. This approach can improve the understanding and management of HNC, contributing to global discussions and advancing treatment and prevention strategies in Egypt.

Abstract
BACKGROUND Parkinson's disease (PD) is a major cause of disability. We aimed to assess the benefit of ultrasonography of the vagus nerve (VN) to compare between PD and healthy controls as well as to deliver reference values of nerve cross sectional area (CSA). MATERIALS AND METHODS We performed a systematic search on Medline (PubMed), Scopus, Embase, and Web of Science, up till July 25, 2022. After article selection and screening, we performed a quality assessment using the Newcastle-Ottawa Scale. Furthermore, a statistical analysis and subgroup analysis was performed. RESULTS Eleven studies were included with a total of 809 participants (409 PD patients and 400 controls). A statistically significant difference in the CSA of the right and left VN between PD patients and healthy controls was observed, indicating the atrophy of VN in PD patients (p < 0.00001). The subgroup meta-analysis for average measurements of VN CSA showed insignificant heterogeneity for age (I2 = 48.67%, p = 0.058), level of measurements (I2 = 57.91%, p = 0.05), and disease duration (I2 = 27.1%, p = 0.241). CONCLUSION Our meta-analysis showed a sonographically detectable degree of neuronal damage in PD, which correlates with VN atrophy with high confidence. Therefore, we believe this is a potential marker for vagus neuronal lesions. Future studies are required to assess the potential clinical correlation.

Abstract
Because of the insidious character and variations in presenting symptoms, Charcot-Marie-Tooth (CMT) disease is challenging to diagnose in children. Diagnosis is based on clinical and nerve conduction studies, as well as genetic examination. Therefore, competent nerve imaging techniques and non-invasive alternatives to nerve conduction studies are a necessity, especially in children. We performed a systematic review and meta-analysis to evaluate the current evidence and effectiveness of ultrasound in investigating nerve cross-sectional area (CSA) in those with CMT compared with healthy controls and to pool the CSA measurements. We included studies published in international peer-reviewed journals that measured nerve CSA by ultrasound in patients with CMT. We implemented double-arm meta-analyses to compare the mean CSA of nerves between patients with CMT and healthy controls by calculating the pooled mean difference in CSA. Moreover, we performed subgroup analyses by stratifying the studies according to the site of CSA measurement and examined the difference in nerve CSA between CMT1A and other CMT types. The included studies provide measurements of 12 nerve roots and nerves (vagus, C3, C4, C5, C6, greater auricular, phrenic, median, ulnar, fibular, tibial and sural nerves) in 628 patients with CMT and 586 healthy controls with a total of 6061 measured nerves. Meta-analyses of sonographic nerve CSA are provided to express nerve ultrasonography in the diagnosis of CMT patient.
