Purpose: The Prevalhep study seeks to determine the prevalence of factors associated with hepatitis C virus (HCV) and B (HBV) in Spanish prisoners Methods: Observational, cross-sectional study which randomly selected 18 Spanish prisons to participate, and with 21 prisoners/CentreResults: There were 378 prisoners selected, 370 of whom had serological HCV and 342 had VHB data. The HCV population were predominantly male (91.6%), of middle age (66.7% contact status with HBV (HBcAb+ and/or HBsAg+), while 37.5% were susceptible to HB. Conclusions:The prevalence of HBV and HCV has decreased in the Spanish prison population, probably as a result of decrease in IDU transmission, and an increase in immigrant prisoner population that does not have this risk behaviour.[Word count = 198]

Randomized trials of thienopyridines in patients with vascular disease demonstrate that thienopyridines are effective in reducing vascular events when compared with placebo/control or aspirin, as well as when used in combination with aspirin in patients undergoing intracoronary stent implantation. The CURE trial is a large international study to determine if acute and long-term treatment with the combination of clopidogrel and aspirin is superior to aspirin alone in patients with acute coronary syndrome.

Objective: To determine the prevalence and associated factors of HIV infection amongst inmates in Spain. Material and Methods: Observational and transversal study (June 2008). For 62,000 inmates an "n" of 364 was determined (5% variability, error correction α 5% and 10% missing). 18 prisons were randomly selected and 21 inmates/prison. Frequency measurement: prevalence. Magnitude of the association: odds ratio of prevalence (ORP) with 95%. Statistical significance p<0.05. results: 371 prisoners were studied (91.6% male, 66.9% ≤ 40 years, 60.6% Spanish, 23.5% IDU and 71.2% incarcerated <5 years). HIV prevalence was 10.8% (CI: 7.5 to 14). 85% were co-infected with HCV, 12.5% with HBV and HCV and 63.2% with M. tuberculosis. This represents a proportion to the prison population of 9.2%, 1.3% and 6.7% respectively. HIV infection was associated with: a) > 40 years (p <0.01), b) imprisoned> 5 years (p <0.001), c) non-Arab (p <0.01), d) Spanish nationality (p <0.001), e) IDUs (p <0.001), f) co-infected with HCV (p <0.001), and g) co-infected with HBV (p <0.001]. Multivariate analysis confirmed the association: a) ≥ 40 years [
