Purpose. The purpose of our study is to evaluate the level of evidence (LOE) of spine surgery publications in the Arab countries and compare it with standard international literature in spine surgery and to determine the stand of the Arab nations academic production with that of the global one. Methods. An online search using “PubMed” and “Google Scholar” was carried out, using search terms related to spine surgery such as “Spine surgery,” “Scoliosis,” “Herniated disc.” Each article was reviewed and graded by two reviewers using Oxford Centre for Evidence-Based Medicine (OCEBM) Levels of Evidence scale. Results. We have identified 434 articles that met the inclusion criteria; 56% were level IV studies. The most common study design was case reports (42%). The number of Arab countries with publications in spine surgery was 18 countries. The country with the highest rate of publications was Egypt (26%). The quantity of the published studies increased from 151 in (2000–2008) to 283 in (2009–2015). There is statistical significance between high and low LOE articles (p = 0.0007). Conclusion. We have observed that LOE has not changed significantly over the period of 15 years and that much of the publications are of a low LOE (levels III and IV). We, herein, emphasize the need for spine surgeons in the Arab countries to conduct studies of higher LOE.
The aim of this study is to investigate the relationship between isocitrate dehydrogenase-1 (IDH1) mutation and O6-methylguanine-DNA methyltransferase (MGMT) promoter methylation with recurrence-free interval in glioblastoma patients treated with chemoradiotherapies. Clinical data were collected from 82 patients with totally resected glioblastoma and treated with adjuvant therapies from 2014 to 2019. IDH1 mutation was assessed by immunohistochemistry and MGMT promoter methylation was assessed by different sequencing methods. IDH1 mutation was present in 32 cases and 50 cases were IDH1 wildtype; 54 and 28 patients had unmethylated and methylated MGMT promoter, respectively, Of the 82 patients, 62 patients received chemoradiotherapy while 20 patients only received radiation. Approximately, 61% of patients had a tumor recurrence after 1 year, and 39% showed a recurrence before 1 year of treatment. There was no significant relationship between IDH1 mutation and MGMT promoter methylation (p-value = 0.972). Patients with IDH1 mutation and their age <50 years showed a significant difference in recurrence-free interval (p-value = 0.014). Difference in recurrence-free interval was also statistically observed in patients with unmethylated MGMT promoter and treated with chemoradiotherapies (p-value = 0.031), by which they showed a late tumor recurrence (p-value = 0.016). This revealed that IDH1 mutation and MGMT methylation are independent prognostic factors in glioblastoma. Although IDH1-mutant glioblastomas showed late tumor recurrence in patients less than 50 years old, the type of treatment modalities may not show additional beneficial outcome. Patients with unmethylated MGMT and IDH1 mutation, treated with different chemoradiotherapies, showed a late tumor recurrence.
Coronavirus disease 2019 (COVID-19) infection is considered a multisystem disease rather than solely affecting the respiratory system. In addition, many reports have described neurological manifestations of this disease; yet reports on spinal cord involvement, especially in pediatrics, are still limited. We describe a case of a 15-year-old male with COVID-19, who presented with sudden paraplegia and urinary incontinence, preceded by a two-day history of fever. Upon clinical and radiological assessment, he was diagnosed with acute hemorrhagic myelitis. A remarkable motor improvement upon a nine-month follow-up was perceived. Our case illustrates that serious complications can arise even though COVID-19 causes milder disease in pediatrics. We advocate for vaccinating the pediatric population to prevent such occurrences.
Objectives:To quantify and evaluate the level of evidence (LOE) of Saudi publications in abdominal surgery and correlate the obtained results with that of other similar national and international studies.Methods:Study design was a systemic review. Literature search strategy was developed to retrieve available articles between January 2000 and December 2016 that are related to abdominal surgery utilizing PubMed and Google Scholar. Retrieved articles were analyzed in depth with several parameters, then evaluated using (OEBM) level of evidence scale.Results:One hundred and ninety-eight articles met the inclusion criteria. Of these, 50.5% were level III evidence studies. The most common study design was case reports (47%), and academic institutions had the highest rate of publications (47%).Conclusion:Saudi research in abdominal surgery published between 2000-2016 are of lower quality and of III and IV LOE, which is in the consistency with other specialties. We emphasize the need for promotion of a national and institutional research studies of I and II LOE with collaboration between different health care institutions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
