World Neurosurg 2024; 191:234-244. [PMID: 39181237 DOI: 10.1016/j.wneu.2024.08.079] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2024] [Accepted: 08/13/2024] [Indexed: 08/27/2024]
Abstract
BACKGROUND The use of bibliometric analysis studies allows for the precise assessment of high impact contributions to various fields of study. A bibliometric assessment of academic works cited in filed patents enables tracking the academic studies which have been most influential in the development of new technologies in spine surgery. METHODS The Lens database was utilized to retrieve scholarly articles related to the field of spine surgery, with special focus on spinal fusion and biologics. Scholarly works cited in patents were organized by publishing journal, article topic, study type, publishing institution, and authors information. Such publications were also categorized by country of origin and, for U.S. patents, region of origin. RESULTS The employed search criteria yielded 37,005 scholarly works related to spine surgery published between 1889 and 2022 and a total of 947 scholarly works cited in patents from 1968 to 2022. Many of the top contributing authors were orthopedic surgeons while the top 3 authors were biomedical engineers. The region in the U.S. with the most citations in patents and the most scholarly work overall was the middle-Atlantic region. CONCLUSIONS This patent bibliometric analysis provides a general overview of trends in publications impacting spine surgery innovation over time. Our results highlight top instutions and regional contributions to spine surgery innovation within the United States and worldwide. As the first patent bibliometric study providing data on the most technologically impactful scholarly work in spine surgery, this study has not only historical value in terms of documenting the scientific and intellectual property developments in spine surgery in the past 50 years, but also practical relevance insofar as the identified trends and research hotspots that may provide researchers valuable insights regarding future decisions involving research efforts and resources allocation.

Seltzer LA, Couldwell MW, Tubbs RS, Bui CJ, Dumont AS. The Top 100 Most Cited Journal Articles on Hydrocephalus. Cureus 2024; 16:e54481. [PMID: 38510885 PMCID: PMC10954317 DOI: 10.7759/cureus.54481] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 02/19/2024] [Indexed: 03/22/2024] Open
Abstract
Hydrocephalus represents a significant burden of disease, with more than 383,000 new cases annually worldwide. When the magnitude of this condition is considered, a centralized archive of pertinent literature is of great clinical value. From a neurosurgical standpoint, hydrocephalus is one of the most frequently treated conditions in the field. The focus of this study was to identify the top 100 journal articles specific to hydrocephalus using bibliometric analysis. Using the Journal of Citation Report database, 10 journals were identified. The Web of Science Core Collection was then searched using each journal name and the search term "hydrocephalus." The results were ordered by "Times Cited" and searched by the number of citations. The database contained journal articles from 1976 to 2021, and the following variables were collected for analysis: journal, article type, year of publication, and the number of citations. Journal articles were excluded if they had no relation to hydrocephalus, mostly involved basic science research, or included animal studies. Ten journals were identified using the above criteria, and a catalog of the 100 most cited publications in the hydrocephalus literature was created. Articles were arranged from highest to lowest citation number, with further classification by journal, article type, and publication year. Of the 100 articles referenced, 38 were review articles, 24 were original articles, 15 were comparative studies, 11 were clinical trials, six were multi-center studies, three were cross-sectional, and three were case reports with reviews. Articles were also sorted by study type and further stratified by etiology. If the etiology was not specified, studies were instead subcategorized by treatment type. Etiologies such as aqueductal stenosis, tumors, and other obstructive causes of hydrocephalus were classified as obstructive (n=6). Communicating (n=15) included idiopathic, normal pressure hydrocephalus, and other non-obstructive etiologies. The category "other" (n=3) was assigned to studies that included etiologies, populations, and/or treatments that did not fit into the classifications previously outlined. Through our analysis of highly cited journal articles focusing on different etiologies and the surgical or medical management of hydrocephalus, we hope to elucidate important trends. By establishing the 100 most cited hydrocephalus articles, we contribute one source, stratified for efficient referencing, to facilitate clinical care and future research on hydrocephalus.

Abstract
Bibliometrics and citation analysis are popular forms of analyzing medical literature based on article impact as determined by the number of citations an article has received from other publications. Many bibliometric studies published within the past 10 years have assembled lists of highly cited papers, top 100 papers, or citation classics of specialties, subspecialties, and specific morbidities. For pediatric epilepsy, there is only 1 study that bibliometrically examines articles in this subspecialty. Although bibliometrics generally examines trends in the literature, we used bibliometrics as a methodology for determining a core set of pediatric epilepsy articles with the highest impact (ie, citation count) that could be used as an introductory reading list for residents, fellows, and early career epileptologists. Therefore, we searched Web of Science to identify the 100 top-cited pediatric epilepsy articles and develop 10 topic areas into which we sorted each article. These recommended articles could be used as essential readings for pediatric epilepsy.

Abstract
With the many papers published in the field of pediatric neurosurgery, it is often difficult to recognize those that have the most impact on future papers, i.e., citable papers. However, citation analysis allows one to better understand which papers are impacting the field the most. Therefore, the current study aimed to evaluate this literature. The Journal Citation Report database was searched for publications with the words “pediatric neurosurgery” or “pediatric neuro” in the title. Using the Web of Science Core Collection, the top 100 journal articles in pediatric neurosurgery from the selected journals were identified and citation analysis was used to identify the most impactful articles. A search was performed on Web of Science Core Collection by searching for each journal under “Publication Name” and using the Boolean “OR” function to separate fields. The results were ordered by the “Times Cited” category, which provided a list of all the articles from the eight journals appearing in the most cited order. The timeline used was from 1976 to 2021. The top 100 most cited articles were extracted from this list for analysis. The following variables were collected from each scientific article: publication journal, impact factor of journal, title, number of citations, year and month of publication, and type of article. Eight journals were identified on the basis of our search criteria and the articles were sorted by most cited; 1609 pediatric neurosurgery journal articles were screened to select the 100 most cited since 1976. This compilation could serve to help clinicians and researchers to familiarize themselves with the journal articles included in terms of study type, study field, journal of publication, and recurring authors.

Abstract
BACKGROUND In the last 20 yr, the rate of neurosurgical guideline publication has increased. However, despite the higher volume and increasing emphasis on quality there remains no reliable means of measuring the overall impact of clinical practice guidelines (CPGs). OBJECTIVE To utilize citation analysis to evaluate the dispersion of neurosurgical CPGs. METHODS A list of neurosurgical guidelines was compiled by performing electronic searches using the Scopus (Elsevier, Amsterdam, Netherlands) and National Guideline Clearinghouse databases. The Scopus database was queried to obtain current publication and citation data for all included documents and categorized based upon recognized neurosurgical specialties. The h-index, R-index, h2-index, i10-index, and dissemination index (D-Index) were manually calculated for each subspecialty. RESULTS After applying screening criteria the search yielded 372 neurosurgical CPGs, which were included for bibliometric analysis. The overall calculated h-index for neurosurgery was 56. When broken down by subspecialty trauma/critical care had the highest value at 35, followed by spine and peripheral nerve at 30, cerebrovascular at 28, tumor at 16, pediatrics at 14, miscellaneous at 11, and functional/stereotactic/pain at 6. Cerebrovascular neurosurgery was noted to have the highest D-Index at 3.4. CONCLUSION A comprehensive framework is useful for guideline impact analysis. Bibliometric data provides a novel and adequate means of evaluating the successful dissemination of neurosurgical guidelines. There remains a paucity of data regarding implementation and clinical outcomes of individual guidelines.

Abstract
Introduction The Journal of Neurosurgery (JNS) published its first volume in 1944 and has evolved into the top cited journal in the field of neurosurgery. The aim of this study was to determine and characterize the 100 most cited (based on the total number of citations) vs. most relevant (based on the number of citations per year) articles originating in JNS. Methods The top 100 most cited articles in JNS were determined by searching the Web of Science database. Citations per year were additionally calculated for the top 1000 articles by total citations to rank the 100 most relevant articles. Results The median number of total citations for the 100 most cited articles in JNS was 505 (range 383-2200), and the median number of citations per year for the 100 most relevant articles was 21.88 (range 17.31-82.61). The median year of publication for the 100 most cited and most relevant articles was 1990 and 1999, respectively (P < 0.0001). Most articles originated in the United States in both categories (72% and 71%, respectively). The most common topic of study was cerebrovascular on both lists, followed by trauma on the most cited list vs. tumor on the most relevant list. The most relevant list also contained considerably more articles with a higher level of evidence such as systemic reviews/meta-analyses and prospective studies. Conclusions This study highlights the key contributing factors to the growth and flourishing of JNS. It also reveals several discrepancies between the most cited and most relevant articles, with the latter including more recently published articles, more studies addressing tumor, and more level I/1 (NHMRC/CEBM) evidence. Bibliometric analysis serves as a useful tool for clinicians and researchers to appraise published literature and understand the scientific foundation of modern neurosurgery.

Abstract
BACKGROUND AND AIMS The advent of social networking sites has facilitated the dissemination of scientific research. This article aims to investigate the presence of Iranian highly cited clinicians in social networking sites. MATERIALS AND METHODS This is a scientometrics study. Essential Science Indicator (ESI) was searched for Iranian highly cited papers in clinical medicine during November-December 2015. Then, the authors of the papers were checked and a list of authors was obtained. In the second phase, the authors' names were searched in the selected social networking sites (ResearchGate [RG], Academia, Mendeley, LinkedIn). The total citations and h-index in Scopus were also gathered. RESULTS Fifty-five highly cited papers were retrieved. A total of 107 authors participated in writing these papers. RG was the most popular (64.5%) and LinkedIn and Academia were in 2nd and 3rd places. None of the authors of highly cited papers were subscribed to Mendeley. A positive direct relationship was observed between visibility at social networking sites with citation and h-index rate. A significant relationship was observed between the RG score, citations, reads indicators in RG, and citation numbers and there was a significant relationship between the number of document indicator in Academia and the citation numbers. CONCLUSION It seems putting the papers in social networking sites can influence the citation rate. We recommend all scientists to be present at social networking sites to have better chance of visibility and also citation.

Abstract
RATIONALE AND OBJECTIVES The number of citations a publication receives can be used to show its impact on a field of study. It may indicate the educational interest in a given population or underline a perceived or real educational gap. This article identifies and characterizes the 100 top cited publications in radiologic journals as of May 2013. MATERIALS AND METHODS All clinical radiologic journals listed by Thomson Reuters Journal Citation Reports in 2011 were identified. A total of 46 journals were identified, and all articles published within these journals were analyzed for citation counts. The top 100 highly cited articles were recorded. RESULTS The most frequently cited radiologic articles appeared in 9 of the 46 journals. These included 59 articles in Radiology, 17 in Journal of Nuclear Medicine, 9 in the American Journal of Roentgenology, 5 in the British Journal of Radiology, 4 in Investigative Radiology, 2 in American Journal of Neuroradiology, 2 in European Radiology, 2 in Radiologic Clinics of North America, 1 in the Seminars in Nuclear Medicine, and 1 in Pediatric Radiology. The citation values ranged from 422 to 7506 with a mean of 751. Publication dates ranged from 1967 to 2006 with the 5-year period between 1986 and 1990 accounting for the largest percentage of articles. The most frequently studied radiologic modality was magnetic resonance imaging (MRI; 28 articles), followed by vascular/interventional (19 articles) and nuclear medicine (13 articles). The central nervous system was the most frequently studied organ system (22 articles), followed by mixed organ systems (14 articles) and liver (12 articles). CONCLUSIONS The top cited articles in radiologic journals span a wide range of imaging modalities, subspecialties, and organ systems. Topics that occurred frequently in the top 100 cited articles included contrast and radiopharmaceutical characterization, MRI of motion, percutaneous radiofrequency ablation in the liver and percutaneous vertebroplasty. We present a methodology that uses citation analysis to identify and characterize these articles. Its use may aid radiologists, academic organization, and editorial staff in determining areas of imaging interest or perceived educational gap. It also highlights the importance of including classic articles in current imaging education.
