Objectives: The aim of this manuscript was to evaluate results of the questionnaire given to young people before and after the prevention campaign to determine whether the prevention campaign improved HIV/AIDS-related knowledge of young people.

Methods: A total of 533 students completed the pre-test and 496 students completed the post-test. Questionnaire was used as pre/post testing tool. Construct validity and measurement scale were assessed using the factor analysis. Rasch scaling was used to establish common scale for pre/post test and to transform raw score into the interval scale. A non-parametric Mann-Whitney U test was used to compare knowledge in pre-test and post-test.

Results: Students increased their knowledge of HIV/AIDS (Pearson's measure of effect size r = 0.74) and the risk of acquiring HIV infection (r = 0.68) statistically significantly (p = 0.001). Girls (risk estimation: r = 0.78, knowledge: r = 0.81) improved much more than boys (risk estimation: r = 0.57, knowledge: r = 0.62).

Conclusions: This study suggests that, for the selected sample, the prevention campaign was an effective tool to increase young people's knowledge of HIV/AIDS. The authors recommend dividing and tailoring interventions by gender to achieve even more efficient preventive future interventions.

The risk of herpes zoster (HZ) and postherpetic neuralgia (PHN) increases rapidly after the age of 50 years old. The incidence of herpes zoster and PHN appears to be correctly measured albeit irregularly and the immediate and long-term complications are so poorly measured that the perception of a benign disease remains entrenched among professionals and in the general population. Because acute-phase treatments are only marginally effective in reducing the severity and duration of complications, zoster vaccines have been developed over the last twenty years.

Background: Violence against women (VAW) perpetrated by men is a public health problem of significant magnitude that negatively affects the whole society. Unequal gender relations produce differentiated positions in the social structure; gender roles that position men and women differently are defined and which are at the root of VAW. Framed within the European PositivMasc project, the aim of this study was to identify the areas for action to promote positive masculinities in preventing VAW in Spain, based on community stakeholders' perceptions on their importance and applicability.
