Introducción: La constitución de la Red de Investigación en Sida (RIS) constituyó un hito para el impulso de la investigación sobre el VIH en España. Se analiza la investigación española en el área, evaluando específicamente el papel que ha desempeñado la RIS en la misma. Métodos: Se identificaron las publicaciones sobre VIH-sida con la participación de instituciones españolas en la Web of Science a lo largo del período 2010-2019, caracterizando bibliométricamente la actividad investigadora e identificando mediante un análisis de clústeres los ámbitos temáticos de investigación. Resultados: Se han identificado 3.960 documentos (promedio de 396 documentos/año), el 42% de los cuales han sido firmados en colaboración internacional. Los investigadores de la RIS han participado en el 60% de los documentos, presentando una producción científica y citación sensiblemente superior a los autores no vinculados a la misma. Cinco clústeres temáticos articulan la investigación, centrados en el abordaje clínico y terapéutico de las personas que viven con el VIH, la coinfección y la comorbilidad con otras enfermedades, la caracterización genética del virus, el desarrollo de vacunas y el estudio de su transmisión en colectivos específicos o asociado a las conductas sexuales. Conclusión: La investigación española sobre el VIH, impulsada en gran medida por los grupos de la RIS ha alcanzado un estadio de madurez, con un notable incremento de la producción científica, la participación en redes cooperativas internacionales y un destacado impacto y visibilidad.(AU)

Introduction: The establishment of the Spanish AIDS Research Network (RIS) was a milestone for the promotion of HIV research in Spain. We analyse Spanish HIV research, assessing the role that RIS has played in it. Methods: We identified publications on HIV-aids with the participation of Spanish institutions in the Web of Science over the period 2010-2019, characterising research activity by means of bibliometrics and identifying the thematic areas of research through a cluster analysis. Results: A total of 3960 documents have been identified (average of 396 documents/year), 42% of which have been signed in international collaboration. RIS researchers have participated in 60% of the documents, presenting a scientific production and citation significantly higher than authors not linked to the RIS. Five thematic clusters articulate the research, focusing on the clinical and therapeutic approach to people living with HIV, co-infection and co-morbidity with other diseases, the genetic characterisation of the virus, the development of vaccines and the study of its transmission in specific groups or associated with sexual behaviour. Conclusion: Spanish HIV research, largely driven by RIS groups, has reached a stage of maturity, with a notable increase in scientific production, participation in international cooperative networks and an outstanding impact and visibility.(AU)

Scientific mapping of the research output on hypertension in children and adolescents, 2010-2018.

OBJECTIVE: The area of pediatric hypertension (HTN) research has seen substantial progress over the last two decades, but no bibliometric analysis has yet been undertaken to describe these advances. This study aims to describe the published research examining HTN in children and adolescents from 2000 to 2018. METHODS: Articles were retrieved using PubMed and the Web of Science. Analyses were performed to quantify the evolution of scientific output, identifying the leading journals, authors, and countries as well as the existing collaboration networks. Likewise, we identified the most cited articles, describing their document type, main topic focus, and the age of the patients studied. RESULTS: In total, we identified 8317 articles in the Web of Science. The annual number of publications doubled over the study period. Articles were published in 1415 journals, mainly in the categories of Peripheral & Vascular Diseases and Pediatrics. The USA dominated scientific production in the field. Regarding researcher productivity, the top 202 authors participated in 20% of the articles, and there were 47 stable research clusters, with the largest component made up of 17 authors. Altogether, there were 145 most cited articles, with an irregular annual distribution; about half focus on HTN itself, while the rest study associated disorders and conditions. CONCLUSION: This is the first study to analyze scientific output on HTN in children and adolescents. The snapshot that emerges is of a research area that is growing but is still in a relatively early phase of development.

Worldwide Scientific Research on Nanotechnology: A Bibliometric Analysis of Tendencies, Funding, and Challenges.

The main objective of this investigation was to analyze the scientific production in global research on nanotechnology, integrating scientific production, funding of studies, collaborations between countries, and the most cited publications. The source for obtaining the research papers for our analysis was the Science Citation Index Expanded from the Web of Science. A total of 3546 documents were extracted during the period of 1997-2018. Food science & technology, chemistry (applied and analytical), spectroscopy, and agriculture appeared as the main areas where the articles were published. Most prolific and cited journals were Analytical Methods, Journal of Agricultural and Food Chemistry, and Food Chemistry. The co-word analysis showed the relationships between "nanoparticles", which is the central word, and "silver nanoparticles", "delivery systems", and "zinc-nanoparticles". The most productive countries were China (1089 papers), the United States (523), Iran (427), and India (359). The main cited topics deal with the biomedical applications of nanoparticles, its synthesis from plants, and its applications in food science. The results highlight an important collaboration between institutions and countries. The availability of funding for research in nanotechnology was remarkable compared to other fields. The multidisciplinarity of the nanotechnology field is one of the main features as well as one of the central findings.

Conclusions The last decade has seen a significant increase in the scientific collaboration between Latin American and European in drug addiction studies, where Brazil and Mexico stand out in Latin American countries, as well as Spain and Italy in Europe. The role of the United States leadership in international research networks is emphazided and identified, occupying an intermediary role in the collaboration between different countries and continents.

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.

Introducción y objetivos. La Sociedad Española de Cardiología celebra anualmente un congreso nacional en el que se presentan numerosas comunicaciones. Sin embargo, se desconoce si posteriormente se publican como artículos y en qué revistas. Nuestro objetivo es identificar el grado de publicación de estas comunicaciones y analizar sus características bibliométricas. Métodos. Se seleccionó aleatoriamente una muestra de 300 comunicaciones presentadas de forma oral durante los congresos de 2002, 2005 y 2008. La identificación de los trabajos publicados se realizó mediante búsqueda en las bases de datos Science Citation Index-Expanded, Scopus, Índice Médico Español e Índice Bibliográfico Español en Ciencias de la Salud. Resultados. De las 300 comunicaciones, 115 derivaron en 147 artículos publicados (el 38,33% de publicación). El congreso que obtuvo un mayor índice de publicaciones fue el de 2005 (43%). El mayor número correspondió al área de cardiología pediátrica/cardiopatías congénitas (58,8%). El mayor porcentaje de trabajos se publicó a los 2 años de la celebración del congreso (30,61%). Los artículos se han publicado en 57 revistas, de las que han pblicado el mayor número de artículos Revista Española de Cardiología (n = 55; 37,41%) y European Heart Journal (n = 8; 5,44%). Conclusiones. El alto porcentaje de artículos publicados en revistas de la mitad superior de la categoría 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 más de un 60% de las comunicaciones no se publique priva a la comunidad científica de unos resultados potencialmente interesantes (AU)

La mayor parte de los trabajos (64,23%) se ha publicado en colaboración entre instituciones españolas, y el 33,85%, en colaboración con extranjeras. El análisis de la participación institucional ha permitido identificar un gran núcleo o red de relaciones de colaboración institucional que integra 27 instituciones, en la que ocupa un lugar central el Hospital Vall d’Hebron. La colaboración internacional está encabezada por Estados Unidos y países europeos como Reino Unido e Italia. Conclusión. A pesar de la bonanza de los indicadores de colaboración que los caracterizan, es necesario potenciar la colaboración entre autores, instituciones y grupos de trabajo, ya que ésta se relaciona positivamente con la calidad e impacto de la investigación y de las publicaciones medidos a través de las citas (AU)

Introduction. Scientific collaboration is vital for to the advance of knowledge and is especially important in health sciences. The aim of this study is to identify scientific collaboration indicators and co-authorship networks of researchers and Spanish institutions that publish on multiple sclerosis (MS) during the period 1996-2010. Materials and methods. The analyzed papers were obtained from Web of Science and Scopus international databases, and IBECS and IME national databases, applying specific search profiles in each one of them. In order to identify collaboration networks all signed papers were quantified and co-authored measures were obtained, as the different indexes, degree, intermediation and closeness. Results. 1,613 articles were published in the period 1996-2010, 92% of them in collaboration. With 10 or more works signed in collaboration, 20 Spanish research groups in MS were identified. 64.23% of the papers were published in collaboration between Spanish institutions, and 33.85% were in collaboration with foreign institutions. The institutional participation analysis has identified a large network of institutional partnerships that integrates 27 institutions, with the Hospital Vall d’Hebron in a central position. International collaboration is headed by the U.S. and European countries, most notably the UK and Italy. Conclusion. The most collaborative authors, institutions, and work groups in Spanish research in MS have been identified. Despite these indicators that characterize the collaboration in this area, it is necessary to enhance cooperation between them, since this collaboration is positively related to the quality and impact of research and publications (AU)

[Productivity and impact of Spanish research into multiple sclerosis (1996-2010)]. / Productividad e impacto de la investigacion espanola sobre esclerosis multiple (1996-2010).

AIMS: To quantify by means of bibliometric indicators the scientific productivity of Spanish researchers and institutions that publish on multiple sclerosis in national and international journals during the period 1996-2010, and to determine their impact. MATERIALS AND METHODS: Papers under study were obtained from Web of Science and Scopus international databases, as well as IBECS and IME national databases, applying specific search profiles in each. RESULTS: 1613 articles were published in 460 journals, of which 71 were Spanish and 389 non Spanish, being the most productive Revista de Neurologia (n = 204), Multiple Sclerosis (n = 102) and Neurology (n = 97). The articles have been published mostly in English (71.92%) and Spanish (27.40%), participating 4728 authors from 1224 different institutions. The 67.08% of the papers have been cited at least once, but 32.92% have not received citations. The mean number of citations per paper was 12.47 ± 28.42. The most cited journals have been Neurology (n = 1821), followed by Multiple Sclerosis (n = 1124) and Journal of Neuroimmunology (n = 890). CONCLUSIONS: The number of papers has increased steadily from 1996 to 2010, confirming the consolidation and growth of Spanish research in multiple sclerosis, whose results are published in a Revista de Neurologia and Multiple Sclerosis. We emphasize the growing internationalization of the Spanish research on the disease, but it is worrying that a third of the papers has not been cited.

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

BACKGROUND: Publications 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. METHODS: Medline 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. RESULTS: A 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%). CONCLUSIONS: We have found an increase in the number of publications in the field of leishmaniasis. The USA and Brazil led scientific production on leishmaniasis research.

The average number of articles per grant awarded was 1.12, and 1.9 when taking into account only the awards that led to publication. CONCLUSIONS: During the period 2000 to 2006, the Sociedad Española de Cardiología/ Fundación Española del Corazón (Spanish Heart Foundation) provided about €500,000 per year to fund research grants, thereby contributing to the fight against cardiovascular diseases. Almost 60% of grants have led to publications, 73% of which were published in international journals, and 91.34% in national or international journals with an impact factor in the Journal Citation Reports.

[Twenty years of Spanish psychological research in Psicothema (1989-2008)]. / Veinte años de investigación de la Psicología española en Psicothema (1989-2008).

Twenty years of Spanish psychological research in Psicothema (1989-2008). Scientific collaboration and gender equality are two spheres of great interest for the organizations responsible for instigating scientific policies. We have identified the research groups and women's contribution to one of the most outstanding Spanish psychology journals. We have selected papers published during the 1989-2008 period in Psicothema. A bibliometric and network analysis was carried out using the Pajek Software tool. We have analysed 1,718 papers, written by 2,423 authors, 53.45% men and 47.54% women. We have identified 86 research groups made up of 293 researchers. We have observed a high increase of productivity and collaboration in the 1999-2008 period, as well as the consolidation, growth, and evolution of many incipient groups identified in the 1989-1998 period, benefiting from the increased interest and prestige of the journal. Despite the increase in the number of women, rising from 35.71% in 1989 to 48.48 in 2008, we have observed an imbalance with regard to productivity and the order of signatures, where women are relegated to intermediate positions.

La colaboración científica y la igualdad de género constituyen dos destacados temas objeto de atención por parte de los organismos gestores de las políticas científicas. Se identifican los grupos de investigación y la participación de la mujer en una de las principales revistas españolas del área de la Psicología. Se han seleccionado los artículos de investigación publicados en Psicothema entre 1989 y 2008, realizando un análisis bibliométrico y de redes utilizando el software Pajek. Se han analizado 1.718 trabajos en los que han participado 2.423 autores, un 52,45% hombres y un 47,54% mujeres. Se han identificado 86 grupos integrados por 293 investigadores. Destaca el notable incremento de la productividad y colaboración en la segunda etapa (1999-2008), así como la consolidación, crecimiento y evolución de muchos de los grupos incipientes identificados en la primera etapa (1989-1998), procesos favorecidos por el creciente poder de atracción y prestigio de la revista. Aunque el número de mujeres ha experimentado un aumento importante, ya que han pasado de ser un 35,71% en 1989 a un 48,48% en 2008, persisten desequilibrios en relación con la productividad y el orden de las firmas (AU)

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 <> 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.

La producción científica cardiovascular en España y en el contexto europeo y mundial (2003-2007) / Cardiovascular Scientific Production in Spain and in the European and Global Context (2003-2007)

Introducción y objetivos. La publicación de artículos de investigación ha aumentado de manera considerable en los últimos años en todas las áreas biomédicas. El objetivo de este trabajo es determinar el lugar que ocupa la investigación cardiológica española de calidad en el contexto europeo y mundial y su evolución durante el quinquenio 2003-2007. Métodos. Utilizando como fuente de datos la base de datos Science Citation Index Expanded de Thomson Reuters, se comparó la producción científica cardiovascular española con la de los países de la Unión Europea y los más destacados del mundo, así como la productividad relativa respecto al número de habitantes y producto interior bruto y el número de citas recibidas en las revistas del área «Cardiac & Cardiovascular Systems» del Journal Citation Reports (CCS-JCR). Resultados. España ocupa el sexto puesto en el ranking europeo y el noveno en el mundial de la producción científica, pasando al décimo mundial si se consideran únicamente las revistas del primer cuartil del área CCS-JCR. En número de citas recibidas, España ocupa el séptimo lugar europeo y undécimo mundial. En la productividad relativa respecto al número de habitantes y el producto interior bruto, la posición española es menos favorable, ocupando la decimoquinta y la decimoctava posición, respectivamente. Conclusiones. En investigación cardiovascular, España ocupa posiciones similares a otras áreas biomédicas, si bien su situación es menos ventajosa respecto a algunos indicadores demográficos y económicos. Para que se mantengan los niveles adecuados de investigación, es necesario que los gobiernos y las sociedades científicas europeas consideren el fomento de la investigación cardiológica de alta calidad como un objetivo primordial (AU)

An analysis of abstracts presented to the college on problems of drug dependence meeting and subsequent publication in peer review journals.

BACKGROUND: Subsequent 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. METHODS: All 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. RESULTS: 254 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. CONCLUSION: One 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.
