Revisión de los trabajos publicados sobre promoción de la salud en jóvenes españoles.

The objective of this study is to review the health promotion interventions on spanish youths published in Spanish in the 1995-2000 period and to describe them in accordance with the scope within which they have been carried out, the topics addressed, the methodology, the evaluation design used and the results obtained. Two hundred and fourteen intervention were identified. Illegal drugs were the topic on which the largest number of interventions were focused (29.8%), followed by alcohol (15.9%), the risk-related sexual behaviours (14.6%) and leisure time (12.6%). The activities carried out most often were: participation-based educational methods (30.7%), explanatory education methods (11.5%) and the preparation of educational materials (11%). In 80.8% of the cases, some evaluation of the health promotion activities was found. The type of evaluation employed most often was the process evaluation (73.7%), and the medium-long term results evaluation being those employed the least (2.2%). The evaluation methodologies used most often were questionnaires (28.2%). A combination of qualitative and quantitative methods was employed in 13.2% of the cases. The four interventions in which the medium-long term impact was gauged had the purpose of preventing and reducing cigarette smoking and/or drinking and or marijuana smoking, all of these initiatives achieving a reduction in cigarette smoking. In conclusion, it seems necessary to improve the design of the evaluations of the health promotion initiatives addressed to young people in Spain and to increase the dissemination of the same by way of their publication.

Individualized Therapy with Ranibizumab in Wet Age-Related Macular Degeneration.

Individualized treatment regimens may reduce patient burden with satisfactory patient outcomes in neovascular age-related macular degeneration. Intravitreal anti-VEGF drugs are the current gold standard. Fixed monthly injections offer the best visual outcome but this regimen is not commonly followed outside clinical trials. A PRN regimen requires monthly visits where the patient is treated in the presence of signs of lesion activity. Therefore, an early detection of reactivation of the disease with immediate retreatment is crucial to prevent visual acuity loss. Several trials suggest that "treat and extend" and other proactive regimens provide a reasonable approach. The rationale of the proactive regimens is to perform treatment anticipating relapses or recurrences and therefore avoid drops in vision while individualizing patient followup. Treat and extend study results in significant direct medical cost savings from fewer treatments and office visits compared to monthly treatment. Current data suggest that, for one year, PRN is less expensive, but treat and extend regimen would likely be less expensive for subsequent years. Once a patient is not a candidate to continue with treatment, he/she should be sent to an outpatient unit with adequate resources to follow nAMD patients in order to reduce the burden of specialized ophthalmologist services.

Role of Age and Sex in the Diagnosis of Early-stage Malignant Melanoma: A Cross-Sectional study.

Age and sex have been identified as predictors of outcome in malignant melanoma (MM). This aim of this multicentre, cross-sectional study was to analyse the role of age and sex as explanatory variables for the diagnosis of thin MM. A total of 2430 patients with MM were recruited. Cases of in situ-T1 MM were more frequent than T2-T4 MM (56.26% vs. 43.74%). Breslow thickness increased throughout decades of life (analysis of variance (ANOVA) p < 0.001), with a weak correlation between Breslow thickness and patient's age (r   = 0.202, p < 0.001). Breslow thickness was significantly less in women (1.79 vs. 2.38 mm, p = 0.0001). Binary logistic regression showed a significant (p < 0.001) odds ratio for age 0-29 years (1.18), and 30-59 years (1.16), and for women (1.09). Age and sex explained 3.64% of the variation observed in Tis-T1 frequency (R2 = 0.0364). Age and sex appear to explain a low percentage of the variation in the early detection of MM.
