“…An often-neglected bibliometric indicator is the rate of uncited publications. The L0 index is the proportion of uncited items to the total number of papers ( 8 – 10 ). With 102 uncited items from 371, the L0 index is 27.5%.…”

“…To better understand the impact of these pioneers and other researchers and clinicians in this field, we intended to perform a bibliometric analysis. Such analyses can be regarded as the map of medical research and is a study tool using quantitative indicators to understand the effect of research productivity, describing the characteristics of the research and the factors associated with a greater impact ( 8 – 10 ). Previous papers on SFN focused on specific topics (neuromodulation, movement disorders, stereotactic biopsy, and spinal cord injuries) ( 11 – 14 ).…”

“…This study is the first analysis of the productivity of an entire nation. Recently, the first bibliometric analysis focusing on epilepsy in Mexico was published ( 8 , 9 , 16 ). The objectives of the present study were to know: (a) the most studied areas, (b) the factors associated with the impact of the publications, (c) the characteristics of the production, and (d) the most productive institutions and authors nationwide.…”

BackgroundStereotactic and functional neurosurgery (SFN) is a rapidly evolving field and some emerging countries, especially Mexico, have made significant contributions to this discipline. A bibliometric analysis has never been performed in Latin America, and this would be particularly important to show the areas that remain poorly studied, and design research strategies for the future.MethodsScopus was queried using keywords pertaining to functional neurosurgery, restricting the affiliation country to Mexico, and considering documents published after 1949. Added to the initial search, a complementary literature exploration by author, considering the publications of the most productive neurosurgeons, was performed. A descriptive statistical analysis was carried out.ResultsFrom 5,109 articles, only 371 were eligible. Scientific production has gradually increased with time. Epilepsy (31%) and movement disorders (27.4%) were the most studied neurological conditions, whereas the other 41.6% corresponded to pain, behavior disorders, spinal cord injuries, neuromodulation, stereotactic biopsies, and SFN history. Level of evidence was predominantly level V (59.1%). Publication output is highly skewed to Mexico City, which represents 78.4% of national production. Relative to factors associated with impact of research, publications in English had more citations (28.5 mean citations per paper), and journals with an impact factor greater than one had more than 10 mean citations per paper.ConclusionsMexico has experienced an increase in the productivity of SFN literature, addressing the most prevalent issues in the country (epilepsy and motor disorders). However, it is necessary to report studies with a higher level of evidence, as well as to decentralize the research collaborating with national institutions outside Mexico City. On the other hand, it is imperative to promote scientific production in English and in high-impact indexed journals to increase the visibility of our production. We would like to call upon our colleagues in other countries to reproduce our methodology, in order to determine the factors associated with the impact and productivity on SFN research.

“…We sorted them according to the main topic (type of tumour) and to avoid duplications, every article was classified into a single category. As with our previous bibliometric studies [8,9,10] , we considered for analysis: topic, year and journal of publication, country and impact factor of the journal, document type, research area (clinical or basic), number of papers per year, citations and pattern of collaboration (endogamic, national or international participation).

Research on Brain Tumors in Mexico: A Bibliometric Analysis from Latin America

Background: Bibliometrics is a completive method of research and analyses useful to understand the collective contributions of a given scientific community. The detail of the quantity (productivity) and impact as a surrogate marker of quality can shed light on what we have done (number of articles) and how we impact others (citations). It also shows the direction the community can take for further research, guided by its shortcomings and successes. The publications of Latin American medical institutions on brain neoplasms have never been studied. Objective: Analyze a clinical and experimental approach, identifying core journals, type of article, increase of published material with time, number of citations. Additionally, we identified the most researched topics involved in brain tumor literature. Material and methods: We harvested the articles published by at least one author from the Instituto Nacional de Neurología y Neurocirugía from Mexico from its inception in 1964 to 2020. Key bibliometric parameters, as the journal of publication, type of paper, number of articles, and citations were recorded. Results: In cerebral neoplasms, our institution produced 291 articles (clinical versus experimental: 227 vs. 64). With a modest productivity before 2000, the production had increased 8-fold by 2019. The main topic is glioblastoma, also with the highest number of citations. Researchers prefer to conduct original investigations rather than subject reviews. Most papers were published in Archivos de Neurociencias (institutional journal produced in Spanish), most papers published in English were in the Journal of Neuro-Oncology. Discussion: Productivity had an encouraging growth in the last decade, but more emphasis should be given to target international journals, which offer a high number of readers and citations. Strategies to reach these goals have to be found and should be implemented. Conclusion: Research on brain tumors in Mexico has recently shown buoyancy and we should profit from this inertia to give a definitive boost to it, which might benefit authors and institutional prestige. But mainly, with a more robust research, we could find better solutions for our patients, applicable in the national and international context.
