    [EN] The durability of reinforced concrete structures is severely affected by corrosion. This phenomenon entails high economic costs due to the large infrastructure built with this material in developed countries, both roads and buildings. This review shows and discusses different techniques now available for monitoring and controlling reinforced concrete structures by means of sensors. These sensors are sophisticated devices that provide information about the factors inducing the processes of corrosion, and they are very useful for predicting the service life of structures and optimizing the repair strategies. This work analyses different sensor systems and compares their applications, taking into account such factors as location, calibration and evaluation data. Finally, some examples of sensor applications and diverse strategies for developing new sensor systems in the near future are presented.[ES] La durabilidad de las construcciones de hormigón armado está gravemente afectada por los fenómenos de corrosión. Este problema supone un gran coste económico en los países desarrollados debido a la gran infraestructura construida en ellos, tanto vial como edificatoria. En esta revisión se exponen las distintas técnicas disponibles actualmente para monitorizar y controlar mediante sensores las estructuras de hormigón armado. Mediante estos tipos de control existentes es posible obtener información relevante sobre los factores que favorecen los procesos corrosivos, cuya información es de gran utilidad para poder predecir la vida útil de las estructuras y optimizar las estrategias de reparación. Se han comparado entre sí los distintos sistemas de sensores y sus aplicaciones, teniendo en cuenta los factores de ubicación, calibración y evaluación de datos. Finalmente, se presentan varios ejemplos de aplicaciones de sistemas y diversas estrategias a seguir en el desarrollo de nuevos sensores.Llorens-Gámez, M.; Serrano, A.; Valcuende Payá, MO. (2019).

    Background Appendicitis is the most common general surgical emergency worldwide, but its diagnosis remains challenging. The aim of this study was to determine whether existing risk prediction models can reliably identify patients presenting to hospital in the UK with acute right iliac fossa (RIF) pain who are at low risk of appendicitis. Methods A systematic search was completed to identify all existing appendicitis risk prediction models. Models were validated using UK data from an international prospective cohort study that captured consecutive patients aged 16–45 years presenting to hospital with acute RIF in March to June 2017. The main outcome was best achievable model specificity (proportion of patients who did not have appendicitis correctly classified as low risk) whilst maintaining a failure rate below 5 per cent (proportion of patients identified as low risk who actually had appendicitis). Results Some 5345 patients across 154 UK hospitals were identified, of which two‐thirds (3613 of 5345, 67·6 per cent) were women. Women were more than twice as likely to undergo surgery with removal of a histologically normal appendix (272 of 964, 28·2 per cent) than men (120 of 993, 12·1 per cent) (relative risk 2·33, 95 per cent c.i. 1·92 to 2·84; P < 0·001). Of 15 validated risk prediction models, the Adult Appendicitis Score performed best (cut‐off score 8 or less, specificity 63·1 per cent, failure rate 3·7 per cent). The Appendicitis Inflammatory Response Score performed best for men (cut‐off score 2 or less, specificity 24·7 per cent, failure rate 2·4 per cent). Conclusion Women in the UK had a disproportionate risk of admission without surgical intervention and had high rates of normal appendicectomy. Risk prediction models to support shared decision‐making by identifying adults in the UK at low risk of appendicitis were identified

    Seventy four Reference Sites of the European Innovation Partnership on Active and Healthy Ageing (EIP on AHA) have been recognised by the European Commission in 2016 for their commitment to excellence in investing and scaling up innovative solutions for active and healthy ageing. The Reference Site Collaborative Network (RSCN) brings together the EIP on AHA Reference Sites awarded by the European Commission, and Candidate Reference Sites into a single forum. The overarching goals are to promote cooperation, share and transfer good practice and solutions in the development and scaling up of health and care strategies, policies and service delivery models, while at the same time supporting the action groups in their work. The RSCN aspires to be recognized by the EU Commission as the principal forum and authority representing all EIP on AHA Reference Sites. The RSCN will contribute to achieve the goals of the EIP on AHA by improving health and care outcomes for citizens across Europe, and the development of sustainable economic growth and the creation of jobs
