Background And Objective: To assess alcohol-related mortality and premature death in Spain between 1999 and 2004.

Population And Method: The records of deaths according to cause of death were used, grouped by age, sex and 60 diagnostic categories. The number of deaths attributable to alcohol consumption according to sex and age group, the mortality percentages, rates per 100,000 inhabitants adjusted to the European population standard, and potential years of life lost (PYLL) per alcohol-related death up to the age of 70 were calculated.

The purpose of this report was to determine the rate at which abstracts orally presented at the European Congress of Radiology (ECR) 2001 were published in 2001-2005 Medline-indexed journals and to compare publication rates and factors with presentations at the ECR in two different periods (2001 and 2000). Absolute and relative publication rates (APR, RPR) and different publication-related factors were analysed. From 991 abstracts originating from 52 countries, 449 articles (APR 45%) were subsequently published in 125 journals, most frequently in European Radiology (n=79, 18%).

Objective: The aim of this study was to analyze the hypothetical changes in the 2001 impact factor of 52 radiological journals included in the Science Citation Index-Journal Citation Reports by also counting cites proceeding from 73 Spanish journals on different medical specialties. Also, to estimate the possible impact factor of the official Spanish radiology journal, Radiologia, not included in this database.

Materials And Methods: A modified 2001 impact factor of 52 radiological journals and Radiologia was obtained by adding the number of cites in 1999 and 2000 from the medical Spanish journals.

Desired adjustment of methadone dose, perceived participation in dosage regulation, and satisfaction with methadone treatment centres were assessed in a sample of opioid-dependent patients from the Valencia Region (eastern Spain). An independent interviewer asked 278 consecutively arriving patients to answer the survey, and 165 (59.4%) completed it.

Introduction And Objectives: The aim of this study was to evaluate the production of research papers by Spanish authors on diagnostic imaging published in the official journals of two Spanish scientific societies (Revista Española de Cardiología and Radiología) between 1994 and 1998, and to compare publication rates with those of research papers published in foreign cardiological and radiological journals included in Journal Citation Reports.

Material And Method: Specific search profiles were devised to retrieve items from the Indice Médico Español (IME) and MEDLINE databases. The impact factor for non-Spanish journals devoted to different specialties was normalized for the number of papers published.

A survey was carried out to evaluate the satisfaction with methadone treatment centres of methadone-maintained opioid-dependent patients from Spain. Independent interviewers asked 505 consecutively arriving clients from 20 randomly selected centres (14 conventional centres, two bus units, and four prisons) to participate; 370 (73.3%) clients agreed to fill out the questionnaire, and 351 (69.

We adapted the 32-item Verona Service Satisfaction Scale (VSSS-32) to assess opioid-dependent patient satisfaction with services received from methadone treatment centres. The preliminary version of the VSSS for methadone treatment (VSSS-MT) was filled out anonymously and completed by 516 randomly recruited patients. After exploratory factor analysis and item refinement, the definitive 27-item VSSS-MT accounted for 58.
