RESUMO

INTRODUCTION 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. CONCLUSIONS Cuban scientists conduct research on diabetes, but their work is not highly visible in the peer-reviewed literature, particularly in top-ranked journals. The problem is not simply one of publishing more, but of knowing how and where to publish. It is urgent that Cuban universities training health professionals at all levels include instruction on scientific writing.

RESUMO

Una parte importante e imprescindible de la actividad de los científicos y docentes de universidades e institutos de investigación es la divulgación de sus resultados a través de la publicación en revistas especializadas y sobre la base de estas descansa su evaluación. En Cuba la medición de los resultados científicos se realiza por el conteo simple de los artículos que publican los profesionales: Un científico tiene un mayor mérito si publica más artículos, un docente para pasar de una categoría a otra superior tiene que tener en su aval un número determinado de publicaciones; o sea, esta es la etapa cuantitativa por la que aun transitan muchos países. Luego surgieron los métodos para combinar la cantidad con la calidad y entonces se pasa una escala superior que ocurre cuando los trabajos publicados son leídos y son citados en otros artículos, esto ya es una métrica que mide calidad porque significa que la ciencia se ha “consumido.”


An important and indispensable part of the activity of the scientists and teachers of universities and investigation institutes it is the popularization of their results through the publication in specialized magazines and on the base of these rests their evaluation. In Cuba the mensuration of the scientific results is carried out by the simple count of the articles that professionals publish: A scientist has a bigger merit if he publishes more articles, a teacher one to pass from a category to another superior has to have in his reference a certain number of publishing; that is to say, this is the quantitative stage to which still traffic many countries. Then the methods arose to combine the quantity with the quality and then to pass to a superior scale that happens when the published works are read and quoted in other articles, this is already a metric that measures quality because it means that the science has been "consumed."

RESUMO

INTRODUCCIÓN: la dinámica particular de las proteínas derivadas del cerebro en el líquido cefalorraquídeo es diferente a la dinámica de las proteínas derivadas de la sangre. OBJETIVO: describir los datos empíricos de la lectina de unión a manosa y brindar una interpretación teórica de la dinámica de esta proteína a través de la confección un nuevo reibergrama. MÉTODOS: la lectina de unión a manosa en suero y líquido cfalorraquídeo, fue medida en 40 adultos normales a través de un ensayo inmunofluorométrico. El criterio diagnóstico estuvo basado en; muestras controles (pacientes normales) y muestras de pacientes con enfermedades que cursaron con disfunción de barrera sangre-líquido cefalorraquídeo. RESULTADOS: el coeficiente de correlación entre la lectina de unión a manosa en el líquido cefalorraquídeo y en el suero, fue muy bajo. El reibergrama de la lectina de unión a manosa se diseñó de acuerdo con procedimientos previos. CONCLUSIONES: bajo cualquier condición de barrera sangre-líquido cefalorraquídeo, el reibergrama puede identificar la ocurrencia de síntesis intratecal de lectina de unión a manosa.


BACKGROUND: The dynamics of brain derived proteins in cerebrospinal fluid is different from the dynamics of blood-derived proteins. Aim: To describe the empirical data for mannan binding lectin and gives a theoretical interpretation of the dynamics of this protein in cerebrospinal fluid through a new reibergram. METHODS: Serum and cerebrospinal fluid mannan binding lectin were measured in 40 normal adults by immunofluorometric assays. The diagnostic criteria were based in; normal control samples defined clinically and diseases with blood-cerebrospinal fluid barrier dysfunction. RESULTS: Correlation coefficient between cerebrospinal fluid MBL and serum MBL was very low. Mannan binding lectin reibergram was designed according with previous procedures. CONCLUSION: Under all conditions of the blood-cerebrospinal fluid barrier, the reibergram can identify the occurrence of intrathecal mannan binding lectin synthesis.
