Though currently considered a 'black box,' machine learning (ML) has a promising future to ameliorate the health-care burden of stroke which is the second leading cause of mortality worldwide. Through this study, we sought to review the most influential articles on the applications of ML in stroke. Web of Sciences database was searched, and a list of the top 50 most cited articles, assessing the application of ML in stroke, was prepared by 2 authors, independently. Subsequently, a detailed analysis was performed to characterize the most impactful studies. The total number of citations to the top 50 articles were 2959 (range 35–243 citations) with a median of 47 citations. Highest number of articles were published in the journal Stroke and the United States was the major contributing country. The majority of the studies focused on the utilization of ML to improve stroke risk prediction, diagnosis, and outcome prediction. Statistical analysis revealed an insignificant association between the total and mean number of citations and the impact factor of the journal (P = 0.516 and 0.987, respectively). Recent years have witnessed a surge in the application of ML in stroke, with an enhancement in interest and funding over the years. ML has revolutionized the management of stroke and continues to aid in the neurosurgical decision-making and care in stroke patients. [ABSTRACT FROM AUTHOR]

Medically refractory cases of trigeminal neuralgia often require treatment escalation. Surgical options include microvascular decompression and percutaneous ablation. This paper provides a bibliometric analysis of the most influential articles on the surgical management of trigeminal neuralgia. The Web of Science database was queried to identify the top 100 cited articles concerning surgical treatment of trigeminal neuralgia. The search terms used included ALL=(("trigeminal neuralgia" OR "tic douloureux" OR "Fothergill's disease" OR "Trifacial neuralgia") AND ("surgical treatment" OR "surgical management" OR "surgery" OR "neurosurgery") NOT ("radiosurgery" OR "gamma knife")). The extracted variables included the first and senior author names, journal, publication year, institution, and surgical modality. Our bibliometric search yielded 2104 studies, with 41,502 citations overall. Within the top 100 articles, Zakrzewska had the most first author papers (n = 5), and Burchiel had the most senior author papers (n = 6). The Massachusetts General Hospital was the most represented institution (n = 5). The United States was the most represented country (51%). Microvascular decompression was the most studied surgical strategy (51%), followed by percutaneous radiofrequency coagulation (9%), balloon/nerve compression (7%), and glycerol rhizolysis (7%). Some studies assessed multiple treatment modalities (22%). The types of studies included retrospective articles (58%), prospective articles (26%), reviews (10%), anatomic studies (2%), and basic science (1%). Neurosurgery (35%) and the Journal of Neurosurgery (33%) were the most represented journals. The current literature consists of retrospective reviews and mostly describes microvascular decompression for trigeminal neuralgia. Future studies should include further characterization of other surgical modalities such as percutaneous radiofrequency thermocoagulation, glycerol injection, and balloon compression.

This study aimed to determine the bibliometric characteristics of scientific articles on systematic reviews of neurosurgery worldwide. Bibliographic searches were performed in journals indexed by the Web of Science database until 2022, with no language restrictions. A total of 771 articles were ultimately included on the basis of predefined inclusion criteria, which were manually reviewed. The bibliometric analysis involved the use of quantitative bibliometric indicators and network analysis, which were performed using the bibliometrix package in R and VOSviewer, respectively. The first publication was in 2002, and the number of publications increased over time, with the largest number of publications in 2021 (156 articles). The average number of citations per document was 17.36, and the annual growth rate was 6.82%. Nathan A. Shlobin was the author with the most published articles (19 articles). The most cited study was published by Jobst BC (2015). WORLD NEUROSURGERY was the journal with the most publications (51 articles). The country of corresponding authors with the most publications and the greatest number of total citations was the United States. The affiliations with the most articles were University of Toronto (67 articles) and Harvard Medical School (54 articles). The increasing trend during the past 20 years, and especially in the past 2 years, highlights the advancements in various subspecialities in the field. Our analysis revealed that North American and Western European countries are at the forefront of the field. There is a poor output of publications, authors, and affiliations in Latin-American and African countries. [ABSTRACT FROM AUTHOR]

This bibliometric analysis aims to identify the most impactful articles on hemangioblastoma (HB) and evaluate the trajectory of academic literature in the field. The authors performed a title search using the Web of Science database, with ("hemangioblastoma" OR "haemangioblastoma") as a search query. The top 100 cited articles from the years 1900–2020 were sorted by the descending order of the total citation count. The following variables were assessed for each article: title, first author name and institution, publication year, country of origin, citation count, citations per year, and journal impact factor. The query yielded 1918 articles related to the topic of HB that were published between the years 1900 and 2020 in 42 unique journals. The most prolific decade of publication was the 2000s (35%), followed by the 1990s (33%) and the 1980s (11%). The average citation count was 88.3 (range, 47–426), and the mean number of citations per year was 3.74 (range, 0.660–17.8). This is the first bibliometric analysis to evaluate the most influential HB publications. Though a majority of HBs are sporadic, these results suggest a research focus on von Hippel-Lindau–associated tumors. Despite established evidence for the potential to control HB growth with vascular endothelial growth factor inhibition, there are no known clinical trials underway for this investigation. There is a need for consistent treatment guidelines for asymptomatic HBs, as resection can prevent the development of neurological deficits. An improved understanding of the etiology of these neoplasms could promote the development of novel diagnostic and treatment methods. [ABSTRACT FROM AUTHOR]

The journals Pain, European Journal of Pain, and Molecular Pain showed more interested in this field. The United States, Harvard University, and Ralf Baron were the top country, institution, and author, respectively. Global research collaboration was extensive, with the top institutions and authors cooperating with others. [ABSTRACT FROM AUTHOR]

Gliomas are the most common primary malignant tumor of the central nervous system. At the present time, radiotherapy (RT) is the cornerstone of therapeutic approaches, but the worldwide research trends in RT for gliomas in the world are unclear. This bibliometric analysis aimed to investigate trends in glioma RT research since 2011. The Web of Science database was searched, and SigmaPlot 14.0 and VOSviewer software were used to analyze and visualize the trends. Bibliometric analysis of 5106 articles was conducted. While the number of publications per year was relatively steady, the number of citations grew exponentially from 356 in 2011 to 21,051 in 2020. Articles originated from 89 countries, with the majority from the United States. Journal of Neuro-Oncology and Texas A&M University were the journal and institution, respectively, with the highest number of publications. The articles mainly involved oncology, neurology, radiology, and surgery. This bibliometric analysis found an increased focus on glioblastoma, survival, and chemotherapy in glioma RT research.

Our aim was to re-evaluate the h-index of neurosurgical units in the United Kingdom and Ireland because it was 5 years since it was last reported. Using the Web of Science database, we collated cumulative (1950–2020), 10-year (2011–2020), 5-year (2016–2020), and 3-year (2018–2020) data for neurosurgical units in the United Kingdom and Ireland. Data included h-index, number of publications, and average number of citations. In total, 37 neurosurgical units were found in the United Kingdom and Ireland, which we ranked according to h-index. Since last reviewed 5 years previously, some units had changed their position, whereas others had remained reasonably static. The top 5 units were the same for the 10-year h-index between 2015 and 2020. The 5-year h-index showed some variation in the top 5 compared with the 10-year h-index. We were also able to compare 2 other studies with similar methods but differing from ours. The h-index for neurosurgical units is the most reliable bibliometric, which shows the academic standing and correlates well with amount of research grant obtained and size of department. It is particularly useful when calculated for the most recent 10-year and 5-year periods. Neurosurgical units change their rankings over time and, therefore, it is important to update the tables periodically. We propose an online database with open access showing all h-index and bibliometric data for neurosurgical units in the United Kingdom and Ireland. This database could provide a live and dynamic report of the academic standings of those units and could be used for grant applications and reviews. [ABSTRACT FROM AUTHOR]

The purpose of this bibliometric analysis was to identify trends and hot topics in research on lumbar spinal stenosis (LSS) over the past decade, for helping researchers explore new directions for future research in that area. All research articles on LSS, written in English and indexed in the Web of Science database (WoS) between 2010 and 2020, were used. The visualization of network and in-depth bibliometric analysis including the number of publications, countries, institutions, journals, authors, cited references, and key words was carried out with the help of CiteSpace. A total of 4033 papers (3577 original articles and 476 reviews) were identified and included in the study. The most productive year was in 2019. The Spine was the journal that published the highest number of articles and received the most citations. The most productive country and institutions in this field were the United States and Seoul National University, respectively. Kim HJ was the most prolific author, and Deyo RA ranked the first in the cited authors. The most cited article was published in 2010 by Deyo et al. and described the complications and charges index for LSS. From the coword cluster analysis, there were 3 frontiers in lumbar spinal stenosis: intervention, outcomes, and pathogenesis. We have summarized the literature on LSS in the past decade including publication information, country, institution, authors, and journal. Research on minimally invasive surgery, outcomes, and gene therapies in LSS will be hot topics in the future. [ABSTRACT FROM AUTHOR]

Artificial intelligence (AI) has the potential to augment clinicians' diagnostic and decision-making capabilities. It is well suited to identify patterns and correlations within data sets and may be applied to identify elements of importance in complex and data-laden areas such as patient selection, diagnostics, treatment, and outcome prediction. The development of modern neurosurgery has been dependent on major technological advances. In line with this, a growing interest is seen in the use of AI to assist in neurosurgical research and enhance neurosurgical practices. A bibliometric analysis of the 50 most-cited articles alluding to the use of AI in neurosurgery, from inception until July of 2022, was undertaken using the Web of Science database. Statistical analyses were performed on R. The citation count ranged from 29 to 159 (mean: 51.9, standard deviation: 24.8), and the top-cited article was a 2018 systematic review published in World Neurosurgery. Most articles were published after 2015 (85%). The United States was the largest contributing country on the list with 22 articles. Four first and last authors, each, had 2 or more publications. Female first and last authorship was attributed to 18% and 0% of the articles, respectively. This review highlights the most-impactful articles pertaining to AI in the field of neurosurgery. Although female authors were significantly underrepresented on the list, their work was at least as impactful as their male peers. Finally, the striking dominance of articles originating from the developed world raises concerns as to the future of AI in attending to the global health crisis. [ABSTRACT FROM AUTHOR]

Extracranial-intracranial (EC-IC) bypass is a procedure in which a blood vessel outside the skull is connected to one inside the skull to improve cerebral blood flow. Certain aneurysms cannot be treated through standard clipping, and EC-IC bypass may be recommended in such cases. A vast body of literature exists on the use of EC-IC bypass as a treatment for cerebrovascular disorders. While beneficial to surgeons, these publications may not reach all the intended audience, which encourages the use of bibliometric analyses. Although a fraction of historically meaningful publications may not have been sufficiently valued through citation count, bibliometric analysis is the gold standard for assessing the impact of a publication. Using bibliometric analysis, we queried the Web of Science database to identify the 50 most impactful publications on EC-IC bypass based on citation count. The literature search retrieved 125 publications that met inclusion criteria, from which the top 50 most-cited ones were selected. The mean number of citations for each article was 117.06 (range 35–1437). Case reports and series constituted 15 (30%) of the top 50 publications on EC-IC bypass, followed by 8 (16%) editorials and 7 (14%) randomized controlled trials. A total of 265 authors in 10 countries contributed to the 50 manuscripts, which were published in 15 different journals. We retrieved the top 50 most-cited articles on EC-IC bypass surgery and identified the landmark publications to provide a foundational understanding of the procedure as a treatment for complex disorders.
