    La primera parte presenta una breve introducción sobre la actividad científica en psicología en España, Portugal y América latina. La segunda, un estudio empírico, estudia la visibilidad internacional de la producción científica de esos piases durante 1975-1990. Se analizan 2.438 referencias bibliográficas de artículos de revistas obtenidas de tres bases de datos (psyclit, pascal y psyndex). Se obtienen indicadores bibliométricos de productividad por periodos, piases, idiomas, autores y revistas de publicación. Se analiza el contenido temático de los documentos y de las revistas, junto con el factor de impacto esperado (fi) y se obtiene el índice de coautoría. El crecimiento de la producción es de tipo exponencial. España es el país más productivo, seguido por brasil, México, argentina y chile. Hay mas producción de temas de bio-fisico y neuro-ciencias. El idioma más utilizado es el inglés y la institución mas productiva la universidad. Se confirman las hipótesis: mayor gasto en i+d correlaciona con mayor producción; las áreas afines a las ciencias "duras" publican mas en revistas extranjeras, presentan índices de coautoría y valores fi mas altos que las afines a las ciencias sociales. Se concluye que la aportación a nivel internacional de los autores se corresponde, solo parcial o indirectamente con las publicaciones nacionales

    The objective of this work is to approach the state of the art of the user’s studies in about Quality Management and Evaluation of data bases, and to apply the existing models to a real case: the ISOC data base. To this end, two questionnaires have been designed: one aimed to end users and the other to reference librarians. The results show the differences between the two groups in the use, reasons for consultation, objectives and satisfaction. A difference in objectives and level of satisfaction has also been found between the two main users: researches and professors by one hand, and students, by the other. The results allow to establish a map of the use of ISOC data base and to obtain some value indicators. It is concluded that ISOC is pretty used and generally well valued. This kind of studies have proved to be necessary in order to follow up users’ requirements

    (1) Aims: Patients receiving antitumor necrosis factor (anti-TNF) therapy are at risk of developing tuberculosis (TB), usually due to the reactivation of a latent TB infection (LTBI). LTBI screening and treatment decreases the risk of TB. This study evaluated the diagnostic performance of different LTBI screening strategies in patients with inflammatory bowel disease (IBD). (2) Methods: Patients in the Spanish ENEIDA registry with IBD screened for LTBI between January 2003 and January 2018 were included. The diagnostic yield of different strategies (dual screening with tuberculin skin test [TST] and interferon-gamma-release assay [IGRA], two-step TST, and early screening performed at least 12 months before starting biological treatment) was analyzed. (3) Results: Out of 7594 screened patients, 1445 (19%; 95% CI 18-20%) had LTBI. Immunomodulator (IMM) treatment at screening decreased the probability of detecting LTBI (20% vs. 17%, p = 0.001). Regarding screening strategies, LTBI was more frequently diagnosed by dual screening than by a single screening strategy (IGRA, OR 0.60; 95% CI 0.50-0.73, p < 0.001; TST, OR 0.76; 95% CI 0.66-0.88, p < 0.001). Two-step TST increased the diagnostic yield of a single TST by 24%. More cases of LTBI were diagnosed by early screening than by routine screening before starting anti-TNF agents (21% [95% CI 20-22%] vs. 14% [95% CI 13-16%], p < 0.001). The highest diagnostic performance for LTBI (29%) was obtained by combining early and TST/IGRA dual screening strategies in patients without IMM. (4): Conclusions: Both early screening and TST/IGRA dual screening strategies significantly increased diagnostic performance for LTBI in patients with IBD, with optimal performance achieved when they are used together in the absence of IMM

    Background: The effectiveness of the switch to another anti-tumor necrosis factor (anti-TNF) agent is not known. The aim of this study was to analyze the effectiveness and safety of treatment with a second and third anti-TNF drug after intolerance to or failure of a previous anti-TNF agent in inflammatory bowel disease (IBD) patients. Methods: We included patients diagnosed with IBD from the ENEIDA registry who received another anti-TNF after intolerance to or failure of a prior anti-TNF agent. Results: A total of 1122 patients were included. In the short term, remission was achieved in 55% of the patients with the second anti-TNF. The incidence of loss of response was 19% per patient-year with the second anti-TNF. Combination therapy (hazard ratio [HR], 2.4; 95% confidence interval [CI], 1.8-3; P < 0.0001) and ulcerative colitis vs Crohn's disease (HR, 1.6; 95% CI, 1.1-2.1; P = 0.005) were associated with a higher probability of loss of response. Fifteen percent of the patients had adverse events, and 10% had to discontinue the second anti-TNF. Of the 71 patients who received a third anti-TNF, 55% achieved remission. The incidence of loss of response was 22% per patient-year with a third anti-TNF. Adverse events occurred in 7 patients (11%), but only 1 stopped the drug. Conclusions: Approximately half of the patients who received a second anti-TNF achieved remission; nevertheless, a significant proportion of them subsequently lost response. Combination therapy and type of IBD were associated with loss of response. Remission was achieved in almost 50% of patients who received a third anti-TNF; nevertheless, a significant proportion of them subsequently lost response

    BackgroundPrevious studies comparing immigrant ethnic groups and native patients with IBD have yielded clinical and phenotypic differences. To date, no study has focused on the immigrant IBD population in Spain. MethodsProspective, observational, multicenter study comparing cohorts of IBD patients from ENEIDA-registry who were born outside Spain with a cohort of native patients. ResultsWe included 13,524 patients (1,864 immigrant and 11,660 native). The immigrants were younger (45 +/- 12 vs. 54 +/- 16 years, p < 0.001), had been diagnosed younger (31 +/- 12 vs. 36 +/- 15 years, p < 0.001), and had a shorter disease duration (14 +/- 7 vs. 18 +/- 8 years, p < 0.001) than native patients. Family history of IBD (9 vs. 14%, p < 0.001) and smoking (30 vs. 40%, p < 0.001) were more frequent among native patients. The most prevalent ethnic groups among immigrants were Caucasian (41.5%), followed by Latin American (30.8%), Arab (18.3%), and Asian (6.7%). Extraintestinal manifestations, mainly musculoskeletal affections, were more frequent in immigrants (19 vs. 11%, p < 0.001). Use of biologics, mainly anti-TNF, was greater in immigrants (36 vs. 29%, p < 0.001). The risk of having extraintestinal manifestations [OR: 2.23 (1.92-2.58, p < 0.001)] and using biologics [OR: 1.13 (1.0-1.26, p = 0.042)] was independently associated with immigrant status in the multivariate analyses. ConclusionsCompared with native-born patients, first-generation-immigrant IBD patients in Spain were younger at disease onset and showed an increased risk of having extraintestinal manifestations and using biologics. Our study suggests a featured phenotype of immigrant IBD patients in Spain, and constitutes a new landmark in the epidemiological characterization of immigrant IBD populations in Southern Europe

    An overview of the current scientific journals evaluation initiatives in Spain is presented. Most of these models are focused on Social Sciences and Humanities journals because of their special features and are targeted to research evaluation activities. Indicators developed in these systems are analysed, including the methodological difficulties that they entail and the relative merits of each in terms of efficiency. Moreover, the criteria used by the evaluation agencies in relation to scientific journals are examined. Finally, a model based on a diverse range of indicators on editorial quality, international visibility, peer review and impact is proposed

    [ES] EI objetivo del presente trabajo es ampliar a un ámbito internacional los resultados presentados en el trabajo anterior «Características y tendencias en Bibliometría en Ciencias Sociales y Humanidades en España)) con el propósito de estudiar las características y tendencias en otros países y de esta forma poder comparar los resultados obtenidos con los anteriores. Los documentos se han obtenido realizando búsquedas bibliográficas en las principales bases de datos internacionales de Información y Documentación Científica y Biblioteconomía, asi como en las de Ciencias Sociales y Humanas (Psicología, Educación, Sociología, etc.) La cobertura temporal abarca el periodo 1981-1990. Se analiza la producción científica, la procedencia geográfica, la evolución cronológica; la orientación temática; etc. Se comparan los resultados entre las diferentes documentos publicados en universidades. Se analizan con más profundidad los documentos publicados en revistas especializadas en Documentación Científica y Biblioteconomía. Debido a que gran parte de trabajos publicados están orientados al estudio de la productividad de los autores y revistas, o al análisis del estado de la cuestión de una disciplina o área particular, existe una gran dispersión en las publicaciones. Los resultados muestran que existen diferencias entre las disciplinas estudiadas se encuentra un mayor porcentaje de publicaciones en Sociología. Educación y Psicología; el porcentaje de literatura orientada hacia la mejora de los servicios en Centros de Documentación o Bibliotecas no es tan bajo como en el estudio antes citado.[EN] The aini of the present paper is to place the results presented previously in the paper «Characteristics and trends of the bibliometric literature in Social Sciences and Humanities in Spain», in an international context in order to study the trends and characteristics in other counties and in that way to be able to compare the results with those obtained earlier. The documents were obtained from the main international databases specialized in Library and Formation Science-Documentation as well as m Social and Hyman Sciences (Sociology, Education' Psychology, etc.). The study covers the period 1981.1090. Scientific production. geographic origin' chronological evolution. thematic orientation are analyzed. Results are compared among the different disciplines. The studies published in journals specialized in Library and Information Science-Documentation are analyzed in greater detail. Since a large par1 of those studies are oriented loaards studies concerning productivity of authors and journals, and concerning the state of the art oí one particular discipline or area; there exists a great dispersion among the publications. The results also show that there exist differences among the various disciplines studied. these type of studies can be found in the area of Sociology, Education and Psychology. The percentage of liteiature conceriiing the use, improvement and management of Information and Documentation Centers as well as Libraries is not as low as that obtained previously.Peer reviewe

    The aim of this note is to communicate and explain the last additions included in the RESH website: an integrated evaluation system based on a diverse range of indicators on editorial quality, peer review, international visibility and impact index. The team developing RESH has been working on establishing a weighted system. This system assigns a different weight for each type of indicator thus enabling the construction of a journal ranking in each discipline or in each sub-discipline. Evaluators, authors or editors can find, in the cited website, the position of each journal in the context of its subject area, and the data justifying the final position of each journal.&lt;br&gt;&lt;br&gt;El propósito de esta nota es comunicar y explicar las últimas mejoras incorporadas a la plataforma RESH, sistema integrado de evaluación que se basa en diversos tipos de indicadores de calidad en relación con el proceso editorial, la revisión por pares, la visibilidad internacional y los índices de impacto. El grupo que desarrolla RESH ha estado trabajando en la puesta a punto de un sistema de baremación que adjudica diferente peso a los indicadores que miden los diferentes aspectos de la calidad, con objeto de poder construir listas jerarquizadas (ranking) de las revistas en el contexto de sus disciplinas y/o de sus áreas del conocimiento. A partir de ahora, evaluadores, autores y editores podrán encontrar en RESH la posición que ocupa cada revista en el contexto de su especialidad, así como los datos que dan origen a la posición final alcanzada por cada revista
