Background It is important for teenagers to have a favorable attitude toward organ donation and transplantation (ODT) in order to increase the number of future donors. To determine the attitude of teenagers in the South East of Spain toward ODT and to analyze the psychosocial variables related to this attitude. Methods The study population consisted of young teenagers in the South East of Spain. A stratified sample was selected by geographical location, sex and age (n = 4, 117). Attitude was assessed using a validated questionnaire about ODT (PCID-ODT Ríos). Statistical analysis: Student's t -test, Chi-squared test and a multivariate analysis. Results The questionnaire completion rate was 87% (n = 3572). Attitude toward ODT was favorable in 46% of cases (n = 1633) and undecided in 43% (n = 1543). Several psychosocial variables had a favorable effect on donation: believing that one has good information about ODT (Odds Ratio [OR] 1.706); discussing the subject with the family (OR 1.543) and friends (OR 1.818); carrying out pro-social activities (OR 1.642); having a favorable attitude toward cremation (OR 1.466) and autopsy (OR 1.470); and, finally, not being afraid of scars (OR 4.184). Conclusions Teenagers in the South East of Spain are not currently inclined to support organ donation. This attitude is related to many psychosocial factors, mainly connected to not having good information about the subject, not discussing it in social circles and the fear of body mutilation. It would be appropriate to create educational interventional strategies in this group to prevent a negative impact on future donation rates. [ABSTRACT FROM AUTHOR]

A survey intended to ascertain the rate of use and type of contraceptive methods applied by Spanish women aged 40 to 50 years, and to determine the proportion of women in this group at risk of an unwanted pregnancy, was designed and validated. To achieve representative national results for the study population, it was estimated that a sample size of 2000 women was required. Women were selected using probabilistic, stratified random sampling. The survey questionnaire was prepared by the research group with the collaboration of experts in the conduct of population studies of this type. Participants were interviewed face to face by qualified and trained staff from a specialised company external to the research group. Overall, 1039 women (52%) resorted to some contraceptive method, of which (male or female) sterilisation was the most common. We estimate that in Spain there are 840,000 women (31.8%) aged 40 to 50 years at risk of unwanted pregnancy. [ABSTRACT FROM AUTHOR]

Objective Based on the hypothesis that the media represent an important source of information about contraceptive methods and sexuality, this paper reviews the news items about contraception published by four important Spanish newspapers and four women's magazines. Materials and methods All news items appearing from January 1, 1997 to December 31, 2002 in the following publications: El País, El Mundo, ABC, La Vanguardia, Mía, Clara, Ragazza , and Época were collected during the first 6 months of 2003. Results Seven hundred and ten news items about contraception were identified during the period analysed, of which 117 (16.5%) had a negative character. Conclusions Over 80% of news items appearing in the Spanish press in the 1997–2002 period give a positive information about contraceptive methods. [ABSTRACT FROM AUTHOR]

Objectives: Our hypothesis was that during pregnancy nitric oxide acts as mediator in the hemodynamic response to volume expansion.Study Design: The study was performed on 12 rats on days 19 to 20 of pregnancy. Six rats were injected intravenously with hexamethonium bromide plus the inhibitor of nitric oxide synthase L-nitro-arginine methyl ester. For a control group, six rats were injected with hexamethonium bromide plus the L-nitro-arginine methyl ester vehicle. A volume expansion (1.2% body weight) was performed in both groups by intravenous infusion of bovine albumin (6%) solution.Results: In the control group volume expansion induced a hyperdynamic circulation characterized by increased cardiac output, decreased total vascular resistance, and no change in arterial pressure; however, in the study group volume expansion induced a pressor response without hyperdynamic circulation.Conclusion: During pregnancy volume expansion induces a hyperdynamic circulatory state possibly mediated by nitric oxide release. A defect in the release of nitric oxide may be responsible for an inadequate hemodynamic response to volume expansion. [ABSTRACT FROM AUTHOR]
