Bibliometric analysis of leishmaniasis research in Medline (1945-2010)

BackgroundPublications are often used as a measure of success of research work. Leishmaniasis is considered endemic in 98 countries, most of which are developing. This article describes a bibliometric review of the literature on leishmaniasis research indexed in PubMed during a 66-year period.MethodsMedline was used via the PubMed online service of the US National Library of Medicine. The search strategy was Leishmania [MeSH] or leishmaniasis [MeSH] from 1 January 1945 until 31 December 2010. Neither language nor document type restrictions were employed.ResultsA total of 20,780 references were retrieved. The number of publications increased steadily over time, with 3,380 publications from 1945-1980 to 8,267 from 2001-2010. Leishmaniasis documents were published in 1,846 scientific journals, and Transactions of the Royal Society of Tropical Medicine and Hygiene (4.9%) was the top one. The USA was the predominant country by considering the first author’s institutional address (16.8%), followed by Brazil (14.9%), and then India (9.0%), however Brazil leads the scientific output in 2001-2010 period (18.5%), followed by the USA (13.5%) and India (10%). The production ranking changed when the number of publications was normalised by population (Israel and Switzerland), by gross domestic product (Nepal and Tunisia), and by gross national income per capita (India and Ethiopia). For geographical area, Europe led (31.7%), followed by Latin America (24.5%).ConclusionsWe have found an increase in the number of publications in the field of leishmaniasis. The USA and Brazil led scientific production on leishmaniasis research.

La producción científica cardiovascular en España y en el contexto europeo y mundial (2003-2007)

Introduccion y objetivos La publicacion de articulos de investigacion ha aumentado de manera considerable en los ultimos anos en todas las areas biomedicas. El objetivo de este trabajo es determinar el lugar que ocupa la investigacion cardiologica espanola de calidad en el contexto europeo y mundial y su evolucion durante el quinquenio 2003-2007. Metodos Utilizando como fuente de datos la base de datos Science Citation Index Expanded de Thomson Reuters, se comparo la produccion cientifica cardiovascular espanola con la de los paises de la Union Europea y los mas destacados del mundo, asi como la productividad relativa respecto al numero de habitantes y producto interior bruto y el numero de citas recibidas en las revistas del area «Cardiac & Cardiovascular Systems» del Journal Citation Reports (CCS-JCR). Resultados Espana ocupa el sexto puesto en el ranking europeo y el noveno en el mundial de la produccion cientifica, pasando al decimo mundial si se consideran unicamente las revistas del primer cuartil del area CCS-JCR. En numero de citas recibidas, Espana ocupa el septimo lugar europeo y undecimo mundial. En la productividad relativa respecto al numero de habitantes y el producto interior bruto, la posicion espanola es menos favorable, ocupando la decimoquinta y la decimoctava posicion, respectivamente. Conclusiones En investigacion cardiovascular, Espana ocupa posiciones similares a otras areas biomedicas, si bien su situacion es menos ventajosa respecto a algunos indicadores demograficos y economicos. Para que se mantengan los niveles adecuados de investigacion, es necesario que los gobiernos y las sociedades cientificas europeas consideren el fomento de la investigacion cardiologica de alta calidad como un objetivo primordial.

Cardiovascular research in Spain. A comparative scientometric study

A bibliometric analysis of Spanish cardiovascular research is presented. The study focuses on the productivity, visibility and citation impact in an international, notably European context. Special attention is given to international collaboration. The underlying bibliographic data are collected from Thomson Reuters’s Web of Science on the basis of a ‘hybrid’ search strategy combining core journals, lexical terms and citation links especially developed for the field of cardiology.

An analysis of abstracts presented to the College on Problems of Drug Dependence meeting and subsequent publication in peer review journals

BackgroundSubsequent publication rate of abstracts presented at meetings is seen as an indicator of the interest and quality of the meeting. We have analyzed characteristics and rate publication in peer-reviewed journals derived from oral communications and posters presented at the 1999 College on Problems of Drug Dependence (CPDD) meeting.MethodsAll 689 abstracts presented at the 1999 CPDD meeting were reviewed. In order to find the existence of publications derived from abstracts presented at that meeting, a set of bibliographical searches in the database Medline was developed in July 2006. Information was gathered concerning the abstracts, articles and journals in which they were published.Results254 out of 689 abstracts (36.9%) gave rise to at least one publication. The oral communications had a greater likelihood of being published than did the posters (OR = 2.53, 95% CI 1.80-3.55). The average time lapse to publication of an article was 672.97 days. The number of authors per work in the subsequent publications was 4.55. The articles were published in a total of 84 journals, of which eight were indexed with the subject term Substance-Related Disorders. Psychopharmacology (37 articles, 14.5%) was the journal that published the greatest number of articles subsequent to the abstracts presented at the 1999 CPDD meeting.ConclusionOne out of every three abstracts presented to the 1999 CPDD meeting were later published in peer-reviewed journals indexed in Medline. The subsequent publication of the abstracts presented in the CPDD meetings should be actively encouraged, as this maximizes the dissemination of the scientific research and therefore the investment.

Publicaciones derivadas de las comunicaciones a los congresos anuales de la Sociedad Española de Cardiología

Introduccion y objetivos La Sociedad Espanola de Cardiologia celebra anualmente un congreso nacional en el que se presentan numerosas comunicaciones. Sin embargo, se desconoce si posteriormente se publican como articulos y en que revistas. Nuestro objetivo es identificar el grado de publicacion de estas comunicaciones y analizar sus caracteristicas bibliometricas. Metodos Se selecciono aleatoriamente una muestra de 300 comunicaciones presentadas de forma oral durante los congresos de 2002, 2005 y 2008. La identificacion de los trabajos publicados se realizo mediante busqueda en las bases de datos Science Citation Index-Expanded, Scopus, Indice Medico Espanol e Indice Bibliografico Espanol en Ciencias de la Salud. Resultados De las 300 comunicaciones, 115 derivaron en 147 articulos publicados (el 38,33% de publicacion). El congreso que obtuvo un mayor indice de publicaciones fue el de 2005 (43%). El mayor numero correspondio al area de cardiologia pediatrica/cardiopatias congenitas (58,8%). El mayor porcentaje de trabajos se publico a los 2 anos de la celebracion del congreso (30,61%). Los articulos se han publicado en 57 revistas, de las que han pblicado el mayor numero de articulos Revista Espanola de Cardiologia (n = 55; 37,41%) y European Heart Journal (n = 8; 5,44%). Conclusiones El alto porcentaje de articulos publicados en revistas de la mitad superior de la categoria Cardiac and Cardiovascular System del Journal Citation Reports (83%) se puede considerar un indicador objetivo de la calidad de las comunicaciones presentadas en estos congresos. Que mas de un 60% de las comunicaciones no se publique priva a la comunidad cientifica de unos resultados potencialmente interesantes.

Cardiovascular Scientific Production in Spain and in the European and Global Context (2003-2007)

INTRODUCTION AND OBJECTIVES The publication of research articles has increased considerably in recent years in all biomedical fields. The present study examines the position of Spanish quality research in cardiology in the European and world context, and its evolution during the 5-year period 2003-2007. METHODS Using the Science Citation Index Expanded of Thomson Reuters as data source, we compared Spanish cardiovascular scientific production with that of the rest of countries in the European Union and of the most important countries worldwide, along with relative productivity as per number of inhabitants and Gross Domestic Product, and the number of citations in the journals of the <<Cardiac and Cardiovascular Systems>> area of the Journal Citation Reports (CCS-JCR). RESULTS Spain ranks sixth in the European Union and ninth worldwide in scientific production (tenth worldwide if only the journals of the first quartile of the CCS-JCR area are considered). As regards the number of citations received, Spain ranks seventh in the European Union and eleventh worldwide. In terms of relative productivity as per number of inhabitants and Gross Domestic Product, the Spanish ranking is less favorable (positions 15 and 18, respectively). CONCLUSIONS The ranking of Spanish cardiovascular research is similar to that of other biomedical fields, though its position is less favorable in relation to certain demographic and economical indicators. In order to maintain adequate investigational levels, it is necessary for the European governments and scientific societies to regard the promotion of high-quality cardiological research as a priority concern.

Redes de coautorías y colaboración institucional en Farmacia Hospitalaria

Background: Scientific collaboration is necessary for the advance of science. The purpose of this study is to analyse collaboration between authors and Spanish institutions in scientific studies published in FARMACIA HOSPITALARIA, applying methodology derived from the analysis of social networks. Methodology: The study identified pairs of authors and institutions co-authoring or co-signing the same works published in FARMACIA HOSPITALARIA between 1998 and 2007, building collaboration networks using the TextToPajek and Networks-PAJEK programs. Results: 448 articles were analysed, showing an average signature/ article index of 4.79. Applying a collaboration threshold of 3 articles, 26 clusters were formed with principal researchers being Jimenez Torres and Perez Ruixo (n=16 co-authorships) and Ribas Sala and Codina Jane (n=15). Among the institutions, there was significant collaboration between the Complejo Hospitalario Virgen del Rocio and the Complejo Hospitalario Nuestra Senora del Valme (n=4), both in Seville, and between Hospitals Vall d’Hebron (Barcelona), the Hospital de Navarra, and the Universitat de Barcelona (n=4). Discussion: Analysis of the collaboration networks in FARMACIA HOSPITALARIA has made it possible to identify the groups of authors and institutions in the area, as well as their relationships in terms of research and scientific publications. We propose to analyse the changes in these groups over a period of time, as well as to identify collaboration patterns in other national and international journals.

Subsequent full publication of abstracts presented in the annual meetings of the Spanish Society of Cardiology.

INTRODUCTION AND OBJECTIVES The Spanish Society of Cardiology holds an annual national meeting with a large number of presentations but the number of full-text publications resulting from these presentations and the journals accepting these manuscripts is unknown. This study aimed to identify the full-text publication rate of accepted abstracts and to analyze the bibliometric features of subsequent publications. METHODS We randomly selected a sample of 300 oral presentations at the meetings of the Spanish Society of Cardiology in 2002, 2005 and 2008. Subsequent publications were identified through the Science Citation Index-Expanded, Scopus, Índice Médico Español, and Índice Bibliográfico Español en Ciencias de la Salud. RESULTS Of 300 abstracts, 115 resulted in 147 full publications, representing a publication rate of 38.33%. The meeting with the highest publication rate (43%) was held in 2005. The subject category with the highest number of publications was Pediatric Cardiology/Congenital Heart Disease (58.8%). Time to full publication was usually 2 years (30.61%). Articles were published in 57 journals. The journals publishing the highest number of articles were Revista Española de Cardiología (n=55; 37.41%) and the European Heart Journal (n=8; 5.44%). CONCLUSIONS The high percentage of articles published in the upper half of journals listed in Journal Citation Reports under the category of cardiac and cardiovascular system (83%) can be taken as an objective quality indicator of the results presented at these meetings. However, more than 60% of the abstracts did not result in full publications, thus depriving the scientific community of potentially interesting results.
