Background and purpose Prospectively collected data comparing the safety and effectiveness of individual non-vitamin K antagonists (NOACs) are lacking. Our objective was to directly compare the effectiveness and safety of NOACs in patients with newly diagnosed atrial fibrillation (AF). Methods In GLORIA-AF, a large, prospective, global registry program, consecutive patients with newly diagnosed AF were followed for 3 years. The comparative analyses for (1) dabigatran vs rivaroxaban or apixaban and (2) rivaroxaban vs apixaban were performed on propensity score (PS)-matched patient sets. Proportional hazards regression was used to estimate hazard ratios (HRs) for outcomes of interest. Results The GLORIA-AF Phase III registry enrolled 21,300 patients between January 2014 and December 2016. Of these, 3839 were prescribed dabigatran, 4015 rivaroxaban and 4505 apixaban, with median ages of 71.0, 71.0, and 73.0 years, respectively. In the PS-matched set, the adjusted HRs and 95% confidence intervals (CIs) for dabigatran vs rivaroxaban were, for stroke: 1.27 (0.79–2.03), major bleeding 0.59 (0.40–0.88), myocardial infarction 0.68 (0.40–1.16), and all-cause death 0.86 (0.67–1.10). For the comparison of dabigatran vs apixaban, in the PS-matched set, the adjusted HRs were, for stroke 1.16 (0.76–1.78), myocardial infarction 0.84 (0.48–1.46), major bleeding 0.98 (0.63–1.52) and all-cause death 1.01 (0.79–1.29). For the comparison of rivaroxaban vs apixaban, in the PS-matched set, the adjusted HRs were, for stroke 0.78 (0.52–1.19), myocardial infarction 0.96 (0.63–1.45), major bleeding 1.54 (1.14–2.08), and all-cause death 0.97 (0.80–1.19). Conclusions Patients treated with dabigatran had a 41% lower risk of major bleeding compared with rivaroxaban, but similar risks of stroke, MI, and death. Relative to apixaban, patients treated with dabigatran had similar risks of stroke, major bleeding, MI, and death. Rivaroxaban relative to apixaban had increased risk for major bleeding, but similar risks for stroke, MI, and death. Registration URL: https://www.clinicaltrials.gov.

Tapias Ledesma MA, Martín-Pero L, Hernández V, Jiménez R, Gil de Miguel A. Prevalencia de caries en una población escolar de 12 añosAVANCES EN ODONTOESTOMATOLOGÍA/185 RESUMENEl objetivo de este estudio es conocer la prevalencia de caries en una población escolar de 12 años y factores asociados a la misma. Población y métodos: Se ha efectuado un estudio transversal en 452 escolares de 12 años edad de Móstoles. Para determinar el estado dental se ha efectuado una exploración odontológica siguiendo los criterios de la OMS. Medimos la prevalencia de caries en dentición temporal y permanente, así como los índices de caries en dentición temporal (cod, cos) y en dentición permanente (CAOD, CAOS), también medimos el índice SiC, calcularemos los intervalos de confianza al 95%. Utilizamos el programa estadístico SPSS V 13 para realizar todos los cálculos estadísticos y epidemiológicos necesarios del estudio.Resultados: La prevalencia en dentición permanente es del 28,8% (IC 95%: 26,94-31,06). El índice CAOD es del 0,61 (IC 95%: 0,48-0,73) y el índice cod 0,33 (IC 95%: 0,24-0,42). El índice SiC es de 1,82 (IC 95%: 1,55-2,09). Como conclusión podemos resaltar que prevalencia de caries en la población de 12 años de Móstoles ha disminuido. Un 71% de los escolares esta libre de caries en dentición permanente.Palabras clave: Prevalencia, caries dental, SiC. SUMMARYThe objective of study is to know the prevalence of dental caries in schoolchildren 12 year-old and associated factors. Population and Methods: A cross sectional observational study has been carried out in 542 twelve year old schoolchildren in Móstoles. We conducted a dental exploration using the World Health Organization criteria. We then measure the caries prevalence permanent and deciduas and the dmt, dmts, DMFT, DMFS index and its confidence limits at 95%. We used programs SPPS V.13 to carry out all the statistic calculations of the study.Results: The caries prevalence in permanent teeth is 28, 8% (IC95%: 26,06). The DMTF index is 0,61 (IC 95%: 0,48-0,73) and the dmt index is 0,33 (IC 95%: 0,24-0,42). SiC index is 1,82 (IC 95%: 1,55-2,09).In conclusion, the caries prevalence in the 12 year old population from Mostoles to decreed. 71% the schoolchildren are caries free.Key words: Prevalence, dental caries, SiC.
