Marín-Castañeda LA, Armas-Salazar A, González-Salido J, Cid-Rodriguez FX, Lee Á, Carrillo-Ruiz JD. The 100 Most Cited Articles on Functional Neurosurgery in Latin America: A Scientometric Analysis. World Neurosurg 2024; 184:303-309.e8. [PMID: 38280629 DOI: 10.1016/j.wneu.2024.01.106] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2023] [Revised: 01/18/2024] [Accepted: 01/19/2024] [Indexed: 01/29/2024]
Abstract
Significant progress has been made in Stereotactic and Functional Neurosurgery (SFN) within Latin America (LATAM), which can be attributed to the rapid advancements in technology and a growing pool of expertise. However, despite the growing importance of this field, a comprehensive scientometric analysis of LATAM contributions is still lacking. The aim of this study is to shed light on the top-cited articles in the field authored by LATAM researchers. A search of the Scopus database was performed using specific keywords in the field of SFN to retrieve the top 100 most cited articles. Only those with LATAM affiliation for the first or corresponding position were included. The 100 top-cited articles were published between 1978 and 2019 across 47 different journals. On average, these articles had a citation count of 97.2 citations. A total of 635 LATAM authors were identified, including 145 women. Notably, the 5 most productive and impactful authors were Velasco F., Velasco M., Velasco A.L., Cukiert A., and Jiménez F. Within the field of SFN, epilepsy accounted for 47% of the documents, while the remaining 53% encompassed research on psychiatric diseases, movement disorders, translational research, pain, and electrical mapping. Epilepsia emerged as the journal with the highest number of articles. Mexico and Brazil contributed the most articles, with the University of São Paulo and the Hospital General de Mexico being the most productive institutions. This scientometric analysis highlights the impactful research contributions from the region, identifies influential authors and institutions, and emphasizes the necessity for additional collaboration and exploration.

Bibliometric Analysis: Six Decades of Scientific Production from a Nationwide Institution: Instituto de Seguridad y Servicios Sociales de los Trabajadores del Estado (ISSSTE) from Mexico. Healthcare (Basel) 2023; 11:1725. [PMID: 37372844 DOI: 10.3390/healthcare11121725] [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: 03/05/2023] [Revised: 05/18/2023] [Accepted: 06/05/2023] [Indexed: 06/29/2023] Open
Abstract
BACKGROUND This study employed bibliometric analysis to ascertain the research focus areas among a group of Mexican physicians affiliated with the Instituto de Seguridad y Servicios Sociales de los Trabajadores del Estado (ISSSTE). ISSSTE, a healthcare institution catering to a diverse range of diseases, offers a distinctive perspective on the investigated specialties within the realm of health. The primary objective was to identify knowledge gaps in medical care disciplines through a comprehensive examination of scholarly publications. METHODS We retrieved Scopus papers affiliated with "ISSSTE" and saved them as .CSV files. Subsequently, we employed VOSviewer, biblioshiny, and bibliometrix for bibliometric analysis. This enabled us to identify prominent institutions, prolific authors, highly cited researchers, and their respective affiliations. RESULTS Our analysis identified 2063 publications; the specialty internal medicine accounted for the greatest proportion with 831 publications. Original papers accounted for 82% of the total, with 52% of them being written in Spanish. The majority of scientific output, 92%, originated from Mexico City. The annual production has steadily increased since 2010, peaking in 2021 with over 200 publications. However, papers on prevalent conditions, such as metabolic syndrome, received limited citations, and the L0 index (percentage of uncited items) for all papers is close to 60%. Scopus mislabeled one affiliation, and some cases show a low paper-to-author ratio of 0.5 Discussion: Additional concerns, such as honorary authorship due to excessive authors per paper, and the underlying causes of low citation rates in Mexican publications, warrant further examination. Moreover, our research emphasizes the urgency of bolstering research and development funding, which was consistently below 0.5% of GDP for the past four decades, falling short of legal mandates and international benchmarks. We endorse the establishment of robust research collectives in Latin America to address these challenges, foster regional scientific output, and transition from knowledge consumers to knowledge producers, thereby reducing dependence on foreign technology.

Neurocysticercosis research in Mexico: A bibliometric analysis of the Instituto Nacional de Neurología y Neurocirugía Manuel Velasco Suárez. FRONTIERS IN TROPICAL DISEASES 2022. [DOI: 10.3389/fitd.2022.975165] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/13/2022] Open
Abstract
Neurocysticercosis (NCC) is the most common neglected parasitic disease of the central nervous system and leads to many economic and health issues in endemic and non-endemic countries. A bibliometric analysis would shed light on the evolution and development of research in this field, and this is the first study on NCC research. Our institution in Mexico City, the Instituto Nacional de Neurología y Neurocirugía Manuel Velasco Suárez (INNN), has set some milestones in the management of neurocysticercosis and has a decade-long experience and such an analysis in an endemic country like Mexico will be beneficial. We tracked the scientific output in Scopus, from its foundation to March 2021. The studied variables were article type, number of citations, area (clinical/experimental), chronological profile, and preferred journals. In the period from 1964 to 2021, from a total of 3,166 articles from the institution, 232 papers are related to neurocysticercosis with a total of 7,155 citations. The trending topics in the clinical area are pharmacology and pathology in the experimental papers. The number of articles has steadily increased, but NCC is currently a neglected topic that needs further research to better address the disease burden and allow its eradication.
