Suicidal behavior, especially in young populations such as university students, is currently one of the most concerning health problems worldwide, suicide being the second leading cause of death among students. Although literature is still scarce, one of the risk factors that correlates the most with suicidal behavior in young people appears to be problematic internet use (PIU). The aim of this study was to investigate the relationship between PIU and suicidal behavior in a Spanish university population. An ex post facto prospective design was used with a sample of 1,386 Spanish university students (68.7% women and 31.3% men). PIU was assessed by means of the Internet Addiction Test (IAT) and psychological problems by means of the Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM). The results confirm the relationship between PIU and suicidal behavior, principally alongside those of social isolation and depression, this risk being 3.78 times higher among women with PIU and 5.58 times higher in men. PIU appears as a risk factor for suicidal behavior that must be taken into account together with social isolation, subjective distress and depression.

Aunque la literatura aun es escasa, parece que el uso problematico de Internet (UPI) se muestra como uno de los factores de riesgo que mas correlaciona con la conducta suicida en jovenes. El objetivo de esta investigacion es estudiar la relacion entre el UPI y la conducta suicida en poblacion universitaria espanola. Metodo: Se utilizo un diseno prospectivo ex post facto con una muestra universitaria espanola de 1,386 (68.7% mujeres y 31.3% hombres), evaluando el UPI mediante el Internet Addiction Test (IAT) y los problemas psicologicos mediante el Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM). Resultados: Los resultados obtenidos confirman la relacion existente entre el UPI y la conducta suicida, en relacion tambien con el aislamiento social y la depresion principalmente, siendo este riesgo 3.78 veces mayor entre las mujeres con UPI y de 5.58 en hombres. Conclusiones: El UPI se presenta como un factor de riesgo para el suicido a tener en cuenta junto con el aislamiento social, la angustia subjetiva y la depresion.

Background As the long-term efficacy of stereotactic body radiation therapy (SBRT) becomes established and other prostate cancer treatment approaches are refined and improved, examination of quality of life (QOL) following prostate cancer treatment is critical in driving both patient and clinical treatment decisions. We present the first study to compare QOL after SBRT and radical prostatectomy, with QOL assessed at approximately the same times pre- and post-treatment and using the same validated QOL instrument. Methods Patients with clinically localized prostate cancer were treated with either radical prostatectomy (n = 123 Spanish patients) or SBRT (n = 216 American patients). QOL was assessed using the Expanded Prostate Cancer Index Composite (EPIC) grouped into urinary, sexual, and bowel domains. For comparison purposes, SBRT EPIC data at baseline, 3 weeks, 5, 11, 24, and 36 months were compared to surgery data at baseline, 1, 6, 12, 24, and 36 months. Differences in patient characteristics between the two groups were assessed using Chi-squared tests for categorical variables and t-tests for continuous variables. Generalized estimating equation (GEE) models were constructed for each EPIC scale to account for correlation among repeated measures and used to assess the effect of treatment on QOL. Results The largest differences in QOL occurred in the first 1–6 months after treatment, with larger declines following surgery in urinary and sexual QOL as compared to SBRT, and a larger decline in bowel QOL following SBRT as compared to surgery. Long-term urinary and sexual QOL declines remained clinically significantly lower for surgery patients but not for SBRT patients. Conclusions Overall, these results may have implications for patient and physician clinical decision making which are often influenced by QOL. These differences in sexual, urinary and bowel QOL should be closely considered in selecting the right treatment, especially in evaluating the value of non-invasive treatments, such as SBRT.
