Higiene con clorhexidina en unidades de cuidados intensivos para prevenir infecciones nosocomiales. Revisión sistemática

El objetivo de este estudio fue conocer la efectividad de la higiene con clorhexidina para prevenir infecciones nosoco- miales en pacientes adultos ingresados en unidades de cui- dados intensivos (UCI). Se realizó una revisión sistemática de los ensayos clínicos aleatorizados publicados en los últimos 10 años en diferentes bases de datos. Se extrajo información sobre distintos tipos de infecciones, mortalidad, microorga- nismos implicados y microorganismos multirresistentes. Se incluyeron cinco estudios. La intervención no fue efec- tiva en dos estudios debido a una baja frecuencia de infec- ciones y a una alta prevalencia de bacterias gramnegativas, frente a las que la clorhexidina no es tan eficaz. La interven- ción tampoco redujo las tasas de mortalidad. La interven- ción fue efectiva principalmente para prevenir bacteriemias e infecciones por bacterias grampositivas, por lo que podría ser útil en las UCI con altas prevalencias de infecciones de esas características

Multifunctional Ionic Polymers from Deep Eutectic Monomers Based on Polyphenols

Herein we report a novel family of deep eutectic monomers and the corresponding polymers, made of (meth)acrylic ammonium salts and a series of biobased polyphenols bearing catechol or pyrogallol motifs. Phenolic chemistry allows modulating molecular interactions by tuning the ionic polymer properties from soft adhesive to tough materials. For instance, pyrogallol and hydrocaffeic acid-derived ionic polymers showed outstanding adhesiveness (>1 MPa), while tannic acid/gallic acid polymers with dense hydrogen bond distribution afforded ultratough elastomers (stretchability ≈1000% and strength ≈3 MPa). Additionally, phenolic polymeric deep eutectic solvents (polyDES) featured metal complexation ability, antibacterial properties, and fast processability by digital light 3D printing.This work was supported by Marie Sklodowska-Curie Research and Innovation Staff Exchanges (RISE) under grant agreement no. 823989 “IONBIKE”.

Estrategia inteligente basada en envejecimiento de la batería de litio-ion para la gestión energética de autobuses híbridos eléctricos.

El objetivo de este trabajo es proponer una estrategia inteligente basada en el envejecimiento de la batería de litio-ion instalada abordo de vehículo como aplicación de gestión energética. El diseño inicial de una estrategia de gestión energética (EMS) es un paso significativo para cumplir los objetivos de eficiencia en la operación a corto plazo. Sin embargo, debido al envejecimiento de la batería las condiciones iniciales de la EMS pueden variar. La nueva tendencia hacia la digitalización permite monitorizar la operación, brindando la posiblidad de mejorar el desempeño de la estrategia inicialmente propuesta en el largo plazo. Por lo tanto, se propone una metodología para actualizar la EMS con el objetivo de mejorar los costos de operación y extender a vida útil de la batería. La metodología se basa en una optimización mediante programación dinámica para parametrizar las funciones de pertenencia de un control difuso. Los resultados de simulación muestran una reducción en los costos de operación entorno al 47% junto con una extensión de la vida útil de la batería de alrededor de 2.94 %.This paper aims to propose a battery aging conscious energy management strategy. The initial design of an energy management strategy is a significant point to fulfill the efficiency goals in the short term. However, with aging, the initial conditions may vary. The new trend of digitalization allows monitoring the operation, having the possibility to improve the performance of the initially proposed strategy in the long term. Therefore, a methodology for updating the energy management strategy along the bus lifetime is intended to improve the operating costs and extend the battery lifetime. This methodology is based on a dynamic programming optimization, tuning the membership functions in a fuzzy logic control. The simulation results show a reduction of the operation costs up to 47% as long as it stands for battery (BT) lifetime extension of around 2.94%

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Innovation in the Basque vocational training model

216 pThis work seeks to present some of the factors that have accounted for the present-day success of Basque vocational training. To understand what occurred in the course of history to shape the vocational training developed in Euskadi, we have to go back from the 19th century, when the first Schools of Arts and Trades were founded, to the Francoist period, with the involvement of different political, social, economic and other agents… and of course, to the change that transpired in the 1980s, when the Basque Government assumed the competence in educational affairs. The most important key to understanding this success lies in the constant process of innovation, in which quality, creativity, entrepreneurship and internationalisation progressively began to mould this process, which has contributed to the fact that Basque vocational training is acknowledged worldwide
