Comparative study of the perceived quality of life of patients in treatment for cocaine and heroin dependence in Spain: differences by gender and time in treatment.

This is a cross-sectional study in which we compared the perceived quality of life (QoL) of patients receiving outpatient treatment for cocaine (n = 727) and heroin dependence (n = 469), by analyzing differences by gender and time in treatment. Participants were recruited from addictive behavior centers in Spain in 2004. The World Health Organization Quality of Life Assessment Instrument (WHOQOL-Bref) was used as a measure. Analysis of covariance and multivariate linear regression were used. This study shows the relevance of considering the role of gender in QoL studies, and the need to evaluate the effectiveness of treatment in the improvement of QoL. Limitations of the study were noted.

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.

Publicaciones derivadas de las comunicaciones a los congresos anuales de la Sociedad Española de Cardiología / Subsequent Full Publication of Abstracts Presented in the Annual Meetings of the Spanish Society of Cardiology

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)

Exploratory factor analysis and validation study of the lifetime severity index for cocaine, Spanish version (LSI-C-Spanish).

The purpose of the study was to do an exploratory factor analysis and to examine the criterion-related and discriminant validity of the Lifetime Severity Index for Cocaine (LSI-C), Spanish version. A sample of 171 outpatients from 10 drug centers in Spain participated in the study. We conducted the factor analysis with orthogonal rotation and examined correlations between the LSI-C total score and criterion variables as well as the score obtained by a quality of life measure. The factor analysis revealed 2 principal factors that explain 65.8% of the variance. Lower LSI-C scores were associated with taking medication, receiving social help, using cocaine fewer than 30 times during the previous 6 months, and with better scores on quality of life measures. Higher LSI-C scores were associated with unstable housing, overdose, hospitalization, cocaine consumption more than 100 times during the previous 6 months, and more years of drug consumption. The LSI-C Spanish version shows acceptable criterion-related and discriminant validity.

[Coauthorship networks and institutional collaboration in Revista Española de Cardiología publications]. / Redes de coautorías y colaboración institucional en Revista Española de Cardiología.

INTRODUCTION AND OBJECTIVES: The aim of this study was to analyze the patterns of investigator and institutional collaboration in papers published in the Revista Española de Cardiología. METHODS: Details of coauthorship and institutional collaboration involved in articles published in the Revista Española de Cardiología in the period 2000-2005 were recorded and a collaboration index was derived. Collaboration networks were identified using the TextToPajek and PAJEK software tools. RESULTS: Of the 980 papers analyzed, 95.1% had been authored by two or more individuals and 51.43% involved institutional collaboration. The overall collaboration index was 6.23 (standard deviation [SD] 3.1). There was a significant statistical relationship (P< .02) between the collaboration index and the journal section in which the article was published: the Original Articles and Special Reports sections had the highest collaboration indices (mean 7.87 [2.88]; and mean 6.59 [5.02], respectively). The 44 authors who had the highest publication rates were identified. In addition, 25 coauthorship networks involving 112 investigators were observed. CONCLUSIONS: An analysis of collaboration networks led to the identification of a number of author networks in cardiovascular medicine in Spain, and highlighted the interrelationships between them in terms of both scientific research and scientific publications. The most significant aspect of institutional collaboration was the predominance of collaboration within institutions and within Spanish autonomous regions (i.e., 80.57% of collaborations). Possible topics for future study include an analysis of the scientific productivity of the networks identified and of changes in the pattern of collaboration over time.
