RESUMEN Esta investigación tiene por objetivo analizar la evolución temporal de la producción científica en colaboración entre Brasil y España en el área de la Medicina, en el periodo 2002-2011, además de identificar las instituciones y países más productivos y representar y analizar las redes de colaboración institucional entre los países colaboradores. Como fuente de información se utilizó Scopus, por considerarla como la principal base de datos multidisciplinar y con mayor cobertura geográfica. Los documentos analizados se han limitado a los artículos originales. Se recuperaron 1 121 artículos científicos, con un total de 13 906 firmas. Se calculó, para cada año, la tasa de crecimiento anual de la colaboración científica entre Brasil y España. Es significativo reseñar que han participado instituciones de 121 países diferentes, lo que demuestra el alto grado de internacionalización de los trabajos recogidos, y una red de colaboración científica en la que participan 51 países con al menos 15 contribuciones. Se constata el alto grado de colaboración entre estos dos países y el aumento significativo desarrollado a lo largo de los años en el área de la Medicina, así como su participación con otros países, si bien resulta importante resaltar que en más de la mitad de los trabajos (58%) se ve implicado un tercer país, impulsando la cooperación internacional. This study analyzes the development of Spanish-Brazilian collaborative scientific production in the field of medical research between 2002 and 2011, identifying the most productive institutions, the proportion of researchers from each country and bi-lateral collaborative networks. Data were gathered from the Scopus database, which offers broad, international coverage of multidisciplinary research. A study sample of 1,121 original scientific articles signed by 13,906 researchers were retrieved, on the basis of which the annual growth rate of Spanish-Brazilian medical research was calculated. A remarkably high degree of internationalization was found, with 121 countries participating in the papers sampled. Moreover, Fully 51 countries in this international network boast at least 15 contributions. The study finds a high degree of collaboration between Spain and Brazil, and significant growth of collaboration in the area of medical research, including collaborations with other countries, with fully 58% of the sample involving a third country.

The article presents a scientific research on patients with multiple sclerosis (MS) by analyzing data on the bibliographic analysis of articles published from 2003 to 2012. Mentioned is the use of Science Citation Index-Expanded (SCI-E) database from online Web of Science (WOS) platform. Data from "Multiple Sclerosis and Multiple Sclerosis Journal" is also evaluated.

Objective: Reproductive biology is a highly productive area. By analyzing papers published in the major journals in the period 2003–2005, the collaborative patterns were characterized. Design: Original research papers published in 2004 in the journals included in the first quartile of the category “Reproductive Biology” of the Journal Citation Reports (2005) were selected. A bibliometric analysis was carried out with the information obtained, thus building up the networks of coauthorship and institutional collaboration. Result(s): A total of 4,702 papers were analyzed, 96.75% signed in collaboration by two or more authors, the authors per paper index being 5.24; 73.73% of the papers were collaborations between institutions. The U.S.A. and the U.K. headed the absolute productivity ranking in number of papers, and adapting the data with respect to the population, Israel, Australia, and other European countries, such as Finland, Belgium, Sweden, and The Netherlands, had notable contributions. Conclusion(s): We identified the networks of authors who publish in the journals with the greatest impact factor. Only some of the most productive institutions have consolidated collaborative relationships with other institutions. We identified the scientific “isolation” of some countries which, although their productivity is high, have a small number of international collaborations. [Copyright &y& Elsevier]

Objective To study the most important metrics of publication in the field of reproductive medicine over the decade 2003–2012 to aid in discerning the clinical, social, and epidemiologic implications of this relatively new but rapidly emerging area in medical sciences. Design Bibliometric analysis of most-cited publications from Web of Science databases. Setting Not applicable. Patient(s) None. Intervention(s) None. Main Outcome Measure(s) Most productive and frequently cited investigators, institutions, and countries and specific areas of research, scientific collaborations, and comparison of the growth of reproductive medicine research compared with other areas of medical investigation such as obstetrics and gynecology and related science categories. Result(s) We found that 90 investigators with more than 1,000 citations had jointly published 4,010 articles. A continued rise in the impact factor of reproductive medicine journals was seen. The number of publications in reproductive medicine grew more rapidly compared with other science categories. Presently 22% of highly cited articles in reproductive medicine research are published in journals belonging to science categories outside reproductive medicine. The most-cited study groups are situated in the Netherlands, Belgium, Spain, the United States, and the United Kingdom, and collaborative studies have been increasing. Conclusion(s) Reproductive medicine research and subsequent clinical development have attained scientific growth and maturity. High-quality research is increasingly being published in high-impact journals. The increase in (inter)national collaborations seems to be key to the field's success. [ABSTRACT FROM AUTHOR]

Purpose: To characterize the global research trend in radiology departments based on bibliometric indicators.Material and Method: As a source of information, Science Citation Index Expanded and Journal Citation Reports from Web of Science Core Collection (WoSCC) were used. Annual trends, journals of publication, subject categories of journals, collaboration indexes between authors and institutions, network of cowords and most cited papers were identified and analysed. The period of study was 2009-2018.Results: 283,587 downloaded papers were analysed. The number of articles was increasing, as well as the percentage of funded works. Papers were published in 7314 different journals, being the most productive Plos One (5077), followed by American Journal of Roentgenology (4602) and European Radiology (3644). Most productive subject categories of journals were Radiology, Nuclear Medicine & Medical Imaging (86,568 papers), Clinical Neurology (29,722) and Surgery (23,564). International collaboration has increased more than 5 points, from 15.2% in 2009 to 20.7% in 2018.Conclusions: Most cited articles were published in high impact journals outside the scope of diagnostic imaging. Most influential topics included technical innovations within imaging modalities. MRI replaced conventional radiography and CT as the imaging technique of choice in imaging research.
