ABSTRACT
The Asian tiger mosquito, Aedes albopictus (Skuse), is an invasive species native to Southeast Asia. This insect, which is an important vector of arbovirus such as dengue, Zika, and chikungunya, has spread rapidly to several parts of the world over the last few decades. This study employed a bibliometric approach to explore, for the first time, Ae. albopictus research activity and output in Europe. We used the Web of Science Core Collection data source to characterize the current scientific research. A total of 903 publications from 1973 to 2022 were retrieved. We also provided a comprehensive analysis by year of publication; distribution by most productive European countries, institutions, and authors; collaboration networks; research topics; most productive journals; and most cited publications. Results showed a notable increase in the number of studies after the chikungunya virus outbreak in Northeast Italy in 2007. More than 60% of these publications across the entire European continent originated from France and Italy. Research output related to 'population and community ecology' topics was significantly high. The most common type of collaboration was national, which occurred between institutions in the same European country. By providing an overview of Ae. albopictus research in Europe, this work contributes to upcoming debates, decision-making, planning on research and development, and public health strategies on the continent and worldwide.

OBJECTIVE: The analysis of cancer scientific production in Puerto Rico is largely unexplored. The objective of this study was to characterize trends in cancer-related research publications by authors affiliated to Puerto Rican institutions in recent decades. METHODS: Manuscripts were retrieved from the Science Citation Index (SCI) database from 1982 to 2009. Search criterions were that the author's affiliation field contained some institution located in Puerto Rico and that the manuscripts were related to cancer research (according to keywords from the National Cancer Institute' cancer definition). Indexes measured in our analysis included number and type of manuscript, scientific collaboration, author's affiliation, and journal visibility. All the analyses were conducted using ProCite for bibliographic information management and STATA and SEER Joinpoint for the statistical inquiry. RESULTS: From 1982-2009, cancer-related papers authored by scientists located in Puerto Rico came to 451. Over the last three decades the scientific production underwent significant growth (APC = 6.4%, p < 0.05) with the highest peak between 2000 and 2009 (61.4% of all articles). Universities are the local institutional sector with the highest number of authors (81.4%), and the University of Puerto Rico is the most active center in this regard (68.5%). Forty-three percent of the manuscripts (n = 195) were published in 20 journals from which 14 are observed to have high visibility when compared to similar thematic journals. CONCLUSIONS: Cancer-scientific production in Puerto Rico underwent constant growth during the last three decades. A complete understanding of citing, publishing, and collaboration patterns in Puerto Rico is critical to researchers, policy makers, and health-care professionals in order to make informed decisions about cancer research priorities.

OBJECTIVE: The analysis of scientific production in Puerto Rico is largely unexplored. The main aim of this study is to present the characteristics and trends of cancer publications in Puerto Rico's biomedical journals and their relationship with the island's cancer mortality. METHODS: A PubMed and a hard-copy search were performed to retrieve cancer-related articles published in the Puerto Rico Health Sciences Journal and the Boletín de la Asociación Médica de Puerto Rico from 1903 to 2005. Bibliometric indicators studied included the number of authors and references by article, first author's institutional affiliation and country, document type, and language. The study type and tumor classification were also recorded. Cancer proportional mortality (M%) in Puerto Rico and the proportion of cancer-related articles (P%) published were also evaluated. The annual percent change (APC) was estimated to assess trends. RESULTS: A total of 369 articles were retrieved. The institutions with the majority of publications were universities (39.6%), English was the predominant publication language (72.1%), and the principal document type was original papers (69.6%). Epidemiologic studies were the dominant study type (62.1%), and the most studied cancers were digestive (15.4%) and gynecologic (9.6%). Although the P% has increased since 1913 (APC = 1.2%), the M% increased at a faster pace (APC = 2.7%). CONCLUSIONS: Although a growth in the number of cancer publications is observed in these journals, it does not parallel the increase in proportional mortality. A better understanding of the cancer publications in Puerto Rico is essential to establish priorities, define future areas of research, and develop cancer control strategies.

OBJETIVO: El análisis de la producción científica de Puerto Rico está aún en gran parte pendiente. El objetivo principal de este estudio es presentar las características y las tendencias de las publicaciones sobre cáncer en las revistas biomédicas de Puerto Rico y su relación con la mortalidad por cáncer en la Isla. MÉTODOS: Se realizó una búsqueda en PubMed y revistas impresas para localizar los artículos relacionados con cáncer publicados entre 1903 y 2005 en Puerto Rico Health Sciences Journal y el Boletín de la Asociación Médica de Puerto Rico. Entre los indicadores bibliométricos estudiados están el número de autores y referencias por artículo, la afiliación institucional y el país del primer autor, el tipo de documento y el idioma; se recogió también el tipo de estudio y de cáncer. Se evaluaron la mortalidad proporcional por cáncer (M por ciento) en Puerto Rico y la proporción de artículos publicados relacionados con el cáncer (P por ciento). Para evaluar las tendencias se estimó el cambio porcentual anual (APC). RESULTADOS: Se localizaron 369 artículos. Predominaron los artículos originales (69,6 por ciento), de universidades (39,6 por ciento) y en inglés (72,1 por ciento). Los estudios epidemiológicos fueron los más frecuentes (62,1 por ciento) y los tipos de cáncer más estudiados fueron los del sistema digestivo (15,4 por ciento) y los ginecológicos (9,6 por ciento). Aunque el valor de P por ciento ha aumentado desde 1913 (APC = 1,2 por ciento), el valor de M por ciento aumentó más rápidamente (APC = 2,7 por ciento). CONCLUSIONES: Aunque se observó un incremento en el número de publicaciones sobre cáncer en estas revistas, este no se correspondió con el aumento en la mortalidad proporcional por esta causa. Es imprescindible comprender mejor lo relacionado con la publicación científica sobre cáncer en Puerto Rico para establecer prioridades, definir áreas futuras de investigación y desarrollar estrategias para el control del cáncer.

BACKGROUND: The purpose of this study is to analyse the trends in scientific research on transmissible spongiform encephalopathies by applying bibliometric tools to the scientific literature published between 1973 and 2002. METHODS: The data for the study were obtained from Medline database, in order to determine the volume of scientific output in the above period, the countries involved, the type of document and the trends in the subject matters addressed. The period 1973-2002 was divided in three sub-periods. RESULTS: We observed a significant growth in scientific production. The percentage of increase is 871.7 from 1973 to 2002. This is more evident since 1991 and particularly in the 1996-2001 period. The countries found to have the highest output were the United States, the United Kingdom, Japan, France and Germany. The evolution in the subject matters was almost constant in the three sub-periods in which the study was divided. In the first and second sub-periods, the subject matters of greatest interest were more general, i.e Nervous system or Nervous system diseases, Creutzfeldt-Jakob disease, Scrapie, and Chemicals and Drugs, but in the last sub-period, some changes were observed because the Prion-related matters had the greatest presence. Collaboration among authors is small from 1973 to 1992, but increases notably in the third sub-period, and also the number of authors and clusters formed. Some of the authors, like Gajdusek or Prusiner, appear in the whole period. CONCLUSION: The study reveals a very high increase in scientific production. It is related also with the beginnings of research on bovine spongiform encephalopathy and variant Creutzfeldt-Jakob disease, with the establishment of progressive collaboration relationships and a reflection of public health concerns about this problem.

Se estudia el colectivo de investigadores españoles en ciencias médicas. Se emplearon indicadores bibliométricos unidimensionales y relacionales con el fin de analizar los trabajos publicados por los investigadores procesados en la base de datos MEDLINE durante el período 1991-1999. Los resultados indican que la producción científica española en ciencias médicas ha aumentado en más del 70(por ciento). Asimismo, su peso respecto a la producción mundial se incrementó del 1,4(por ciento) al 2(por ciento). La Biología-Bioquímica, la Medicina general, las neurociencias y la Nefrología-Urología son las temáticas en las que se han publicado más documentos. También se ha observado un aumento en el tamaño de los grupos de investigación, así como del índice de coautoría de 4,58 a 5,09 autores/documento. El tipo de documento más utilizado para difundir las investigaciones es el artículo de revista; de las 17 revistas más productivas, 15 son españolas. Los indicadores relacionales utilizados, basados en el análisis de correspondencias, revelan una clara diferenciación entre los sectores institucionales en función de las temáticas en que trabajan sus investigadores. Los hospitales muestran su preferencia por áreas de tipo clínico mientras que las universidades, por las de investigación básica. La actividad científica en el área de ciencias médicas ha experimentado un cambio notable en España, es el sector sanitario, que realiza investigación de tipo aplicado, el de mayor actividad investigadora
