Aproximació històrica al debat sobre la gestió de l'aigua a la política espanyola dels segles XIX i XX

Our paper gives a panoramic picture of the debates that have taken place in Spain about the distribution of water resources. The historic review starts with the colonial crisis and the emergence of reform projects at the end of the XIXth century and ends with the breakdown of the Second Republic in the XXth century. Our research shows the changes of policies undertaken by different governments a long this period and the kind of actors that got active in the debates about how to fight against the country's dryness and drough

Hepatitis A surveillance: sensitivity of two information sources

BACKGROUND: The frequency of mild forms of hepatitis A, especially in children, could lead to underreporting. The objective of the study was to investigate the sensitivity of two surveillance systems, mandatory Statutory Disease Reports and the Microbiological Reporting System of Catalonia, using capture-recapture techniques. METHODS: The study was conducted in Catalonia between 2011 and 2015. Hepatitis A cases reported to two independent surveillance systems were included: Statutory Disease Reports (SDR) and Microbiological Reporting System of Catalonia (MRS). The variables collected were: age, sex, year of declaration, size of municipality ( 15 years (25.5%; 22.8-28.3 vs. 12.1%; 10-14.2). For those born in Spain, the sensitivity was 57.2% (49.6-67.4) in the SDR and 27.1% (23.5-31.9) in the MRS, lower than that for foreign-born patients (58%; 51.2-66.8 vs. 49.1%; 43.4-56.6). In electronically-reported cases, the sensitivity was much higher in the SDR than in the MRS (47.2%; 42.3-52.1 vs. 9.4%; 6.5-12.3). No differences were observed according to sex, size of municipality, and year of declaration or reporting centre. The estimated total number of cases using the Chapman formula was very similar to the adjusted estimate (1121; 985-1258 vs. 1120; 876-1525), indicating the robustness of the results. CONCLUSIONS: The sensitivity of the SDR was greater than that of MRS, especially in patients aged < 15 years, although for patients born abroad the difference in sensitivity was lower. Reinforced surveillance combining the SDR and MRS improves the efficiency in the detection of cases

Estudio prospectivo de eficacia y seguridad de pegaptanib sodio en el tratamiento primario del edema macular secundario a trombosis venosa de la retina

Objectiu:Avaluar l'eficàcia i seguretat de pegaptanib de sodi en el tractament de l'edema macular secundari a obstrucció venosa de la retina (OVR). Mètode: Estudi prospectiu de 16 pacients amb edema macular secundari a OVR tractats mitjançant injeccions intravítrees de pegaptanib de sodi 1mg (0'05ml) a demanda amb un període de seguiment mínim de 6 mesos. Resultat: Millora significativa de l'agudesa visual i del perfil foveal en els nostres pacients. No alarmes de seguretat noves. Conclusions: Pegaptanib de sodi sembla proporcionar beneficis anatòmics i funcionals en el tractament de l'edema macular secundari a trombosis venosa de la retina.Objetivo: Evaluar la eficacia y seguridad de pegaptanib de sodio en el tratamiento del edema macular secundario a obstrucción venosa de la retina (OVR).Método: Estudio prospectivo de 16 pacientes con edema macular secundario a OVR tratados mediante inyecciones intravítreas de pegaptanib de sodio 1 mg (0'05ml) a demanda con un período de seguimiento mínimo de 6 meses.

Does evidence support the high expectations placed in precision medicine? A bibliographic review

Background: Precision medicine is the Holy Grail of interventions that aretailored to a patient’s individual characteristics.  However, the conventional design of randomized trials assumes that each individual benefits by the same amount. Methods: We reviewed parallel trials with quantitative outcomes published in2004, 2007, 2010 and 2013. We collected baseline and final standard deviations of the main outcome. We assessed homoscedasticity by comparing the outcome variability between treated and control arms. Results: The review provided 208 articles with enough information to conductthe analysis. At the end of the study, 113 (54%, 95% CI 47 to 61%) papers find less variability in the treated arm. The adjusted point estimate of the mean ratio (treated to control group) of the outcome variances is 0.89 (95% CI 0.81 to 0.97). Conclusions: Some variance inflation was observed in just 1 out of 6 interventions, suggesting the need for further eligibility criteria to tailor precision medicine. Surprisingly, the variance was more often smaller in the intervention group, suggesting, if anything, a reduced role for precision medicine.  Homoscedasticity is a useful tool for assessing whether or not the premise of constant effect is reasonable.Peer ReviewedPostprint (author's final draft
