- PublicaciónSólo datosA Bibliometric Analysis of the Latin American Research on Stroke 2003–2017(Elsevier B.V., 2019) Alarcon Ruiz, Christoper A.; Diaz-Barrera, Mario E.; Vera Monge, Víctor A.; Alva Díaz, Carlos; Metcalf, TatianaBackground: Stroke is a leading cause of mortality and disability worldwide. Research activity in Latin American countries might be the key to solving, or at least improving, the understanding of stroke-related issues in the region. Our aim was to describe and analyze the research output on stroke in Latin America. Methods: We performed a bibliometric analysis of studies on stroke in Latin America reported from 2003 to 2017 in Scopus-indexed journals. We extracted the annual research, countries, journals, authors, institutions, citation frequency, and journal metrics. The data were quantitatively analyzed. Publication activity was adjusted to the countries by population size. Also, the results from an author and country co-occurrence analysis are presented as network visualization maps using VOSviewer. Results: A total of 2298 Latin American stroke-related reports were identified, most were original research reports (72%). The number of reported studies had increased from 2003 to 2017 (P < 0.001). Brazil was the country with the greatest production with 1273 reports (55.4%), followed by Argentina and Mexico. No association was found between stroke prevalence and mortality and the scientific production of the country. Six universities and three hospitals were the most prolific institutions. A collaborative relationship was found between the United States and Brazil, Argentina, and Mexico. The intraregional collaboration of research on stroke was low among Latin American countries.
- PublicaciónAcceso abiertoCuban scientific production on diabetes, 2000–2017: Peer-reviewed Publications, Collaboration and Impact(Medical Education Cooperation with Cuba, 2019) Corrales Reyes, Ibraín Enrique; Fornaris Cedeño, Yasmany; Dorta Contreras, Alberto Juan; Mejia, Christian R.; Pacheco Mendoza, Josmel; Arencibia Jorge, RicardoINTRODUCTION The steadily increasing prevalence of diabetes globally has captured researchers’ attention. Cuban production of scientific articles on diabetes has not been studied from a bibliometric perspective. OBJECTIVE Characterize the production and impact of research and review articles on diabetes by Cuban authors in journals listed in the Scopus bibliographic database, as well as related collaboration among Cuban institutions and between Cuban and non-Cuban institutions. METHODS A bibliometric analysis was conducted using 2000–2017 data from the Scopus database. The following search strategy was used: descriptor (diabetes), country (Cuba), publication source (journal), article type (original research, review article). Bibliographic indicators of production, visibility, impact and collaboration were examined. RESULTS Cuba contributed 3.2% of Latin American production and 0.1% of global production related to diabetes. Within Cuba’s scientific production (610 articles, 538 original research and 72 review), 85.9% had a Cuban corresponding author (Cuban leadership). In articles with international collaboration (22.9%), however, most (67.9%) had non-Cuban corresponding authors. A total of 47% (287) were articles involving a single institution. Only 11.1% were published in top-ranked journals, and 14.4% were cited >10 times. Cubans were lead authors on 0.3% of the most frequently cited (top 10%) articles on diabetes in Scopus. A total of 38.4% of this production appeared in low-impact journals and 57.9% in Cuban journals. Articles published in English accounted for 30% of total and obtained higher impact in terms of citations than articles in Spanish. The strongest networks for scientific collaboration were those that connected Cuban and US researchers.
- PublicaciónAcceso abiertoProducción científica y licenciamiento de escuelas de medicina en el Perú(Instituto Nacional de Salud, 2019-03) Mayta Tristán, Percy; Toro Huamanchumo, Carlos J.; Alhuay Quispe, Joel; Pacheco Mendoza, JosmelThe new university law 30220 of 2014 introduced the mandatory institutional licensing of all Peruvian universities by the National Superintendence of Higher University Education (SUNEDU, in Spanish). The first undergraduate program to go through this process will be medicine. The licensing of medical programs is necessary to ensure that the conditions in which the program is taught in Peru are adequate, with a high probability of closing some medical schools. Once a medical school has demonstrated that it meets the basic conditions of quality, a qualitative and quantitative evaluation is carried out that includes three criteria: scientific production in the Web of Science, impact measured through the H index, and results of the national medical exam, to determine the years of licensing. This article evaluates the quantitative indicators linked to research using Web of Science and Scopus, in addition to making technical and methodological revisions of them. Suggestions for the other indicators are also covered by this article.
