Public Resource usage in Health Systems: A Data Envelopment Analysis of the Efficiency of Regional Health Systems in Spain

The efficiency in the management of public re sources is on of the main pillars of the welfare state. The objective of this work is to analyze the efficiency of the public resources that regional governments invest in health systems. To this end, Data Envelopment Analysis (DEA) is applied which enable researchers and managers to obtain measurements of efficiency of the analyzed re gions, and proposing corrective steps to achieve ef ficiency for non-efficient regions. Results show that not every health systems present technical efficiency, nor scale efficiencyMinisterio de Economía y Competitividad TIN2009-14378-C02-01Junta de Andalucía TIC-805

Positive and negative motor signs of head motion in cerebral palsy: assessment of impairment and task performance

This paper analyzes the presence of positive and negative motor signs in people with cerebral palsy (CP). Positive motor signs are those that lead to involuntarily increased frequency or magnitude of muscle activity. Negative motor signs describe insufficient muscle activity or insufficient control of muscle activity. In this paper, a head-mounted alternative computer interface based on inertial technology was used to assess motor signs in seven users with CP. Task performance and control of posture was related to the impairment. There are no significant differences between users with CP and healthy control participants in the frequency domain of the head movement. Results suggest that this kind of motor disorders is not related to positive motor signs. Moreover, a control mode based on posture more than on movements is not optimum; an alternative control mode must be specially designed for users with poor postural control

Toxicological Studies of Czech Beers and Their Constituents

Background: Czech beers are unique because they are brewed using specific technology at a particular latitude and for being entirely produced in the area of the Czech Republic. The purpose of this work is the evaluation of toxicological e ects of a variety of freeze-dried Czech beers, their raw materials (malts, hops and yeast) and processed-beer (wort, hopped wort and young beer). Methods: In vivo assays to evaluate the safety and protective e ects in the Drosophila melanogaster eukaryotic system, and the in vitro evaluations of chemopreventive and DNA damage activity using the HL-60 tumour human cell line were carried out. Results: The safe e ects for all the analysed substances and general protective e ects against H2O2 were shown both at the individual and genomic level in the Drosophila animal model, with some exceptions. Moreover, all the substances were able to inhibit the tumour cell growth and to induce DNA damage in the HL-60 cells at di erent levels (proapoptotic, single/double strands breaks and methylation status). Conclusions: The promising e ects shown by freeze-dried Czech beers due to their safety, protection against a toxin, chemopreventive potential and the induction of DNA damage in tumour cells, allow the proposition of Czech beer as a beverage with nutraceutic potentia

Project ARES: Driverless transportation system. Challenges and approaches in an unstructured road

This article belongs to the Special Issue Intelligent Control of Mobile Robotics.The expansion of electric vehicles in urban areas has paved the way toward the era of autonomous vehicles, improving the performance in smart cities and upgrading related driving problems. This field of research opens immediate applications in the tourism areas, airports or business centres by greatly improving transport efficiency and reducing repetitive human tasks. This project shows the problems derived from autonomous driving such as vehicle localization, low coverage of 4G/5G and GPS, detection of the road and navigable zones including intersections, detection of static and dynamic obstacles, longitudinal and lateral control and cybersecurity aspects. The approaches proposed in this article are sufficient to solve the operational design of the problems related to autonomous vehicle application in the special locations such as rough environment, high slopes and unstructured terrain without traffic rules.Research is supported by the Spanish Government through the CICYT projects (PID2019-104793RB-C31 and RTI2018-096036-B-C21), the Comunidad de Madrid through SEGVAUTO-4.0-CM (P2018/EMT-4362) and through EAI of the Ministry of Science and Innovation of the Government of Spain project RTI2018-095143-B-C2

Genetic Structure of the Spanish Population

<p>Abstract</p> <p>Background</p> <p>Genetic admixture is a common caveat for genetic association analysis. Therefore, it is important to characterize the genetic structure of the population under study to control for this kind of potential bias.</p> <p>Results</p> <p>In this study we have sampled over 800 unrelated individuals from the population of Spain, and have genotyped them with a genome-wide coverage. We have carried out linkage disequilibrium, haplotype, population structure and copy-number variation (CNV) analyses, and have compared these estimates of the Spanish population with existing data from similar efforts.</p> <p>Conclusions</p> <p>In general, the Spanish population is similar to the Western and Northern Europeans, but has a more diverse haplotypic structure. Moreover, the Spanish population is also largely homogeneous within itself, although patterns of micro-structure may be able to predict locations of origin from distant regions. Finally, we also present the first characterization of a CNV map of the Spanish population. These results and original data are made available to the scientific community.</p

Intermediate Molecular Phenotypes to Identify Genetic Markers of Anthracycline-Induced Cardiotoxicity Risk.

Cardiotoxicity due to anthracyclines (CDA) affects cancer patients, but we cannot predict who may suffer from this complication. CDA is a complex trait with a polygenic component that is mainly unidentified. We propose that levels of intermediate molecular phenotypes (IMPs) in the myocardium associated with histopathological damage could explain CDA susceptibility, so variants of genes encoding these IMPs could identify patients susceptible to this complication. Thus, a genetically heterogeneous cohort of mice (n = 165) generated by backcrossing were treated with doxorubicin and docetaxel. We quantified heart fibrosis using an Ariol slide scanner and intramyocardial levels of IMPs using multiplex bead arrays and QPCR. We identified quantitative trait loci linked to IMPs (ipQTLs) and cdaQTLs via linkage analysis. In three cancer patient cohorts, CDA was quantified using echocardiography or Cardiac Magnetic Resonance. CDA behaves as a complex trait in the mouse cohort. IMP levels in the myocardium were associated with CDA. ipQTLs integrated into genetic models with cdaQTLs account for more CDA phenotypic variation than that explained by cda-QTLs alone. Allelic forms of genes encoding IMPs associated with CDA in mice, including AKT1, MAPK14, MAPK8, STAT3, CAS3, and TP53, are genetic determinants of CDA in patients. Two genetic risk scores for pediatric patients (n = 71) and women with breast cancer (n = 420) were generated using machine-learning Least Absolute Shrinkage and Selection Operator (LASSO) regression. Thus, IMPs associated with heart damage identify genetic markers of CDA risk, thereby allowing more personalized patient management.J.P.L.’s lab is sponsored by Grant PID2020-118527RB-I00 funded by MCIN/AEI/10.13039/ 501100011039; Grant PDC2021-121735-I00 funded by MCIN/AEI/10.13039/501100011039 and by the “European Union Next Generation EU/PRTR”, the Regional Government of Castile and León (CSI144P20).

Asistencia virtual para apoyo de profesores en nuestra página web

El desarrollo de la inteligencia artificial ofrece metodologías innovadoras. El asistente virtual puede resultar de gran utilidad para un contacto y formación permanente, y es una realidad en creciente expansión en el ámbito empresarial. Este proyecto de innovación se apoya en cuestiones de desarrollo tecnológico de nuestra realidad social, cada vez más inmersa en un mundo de ciencia, tecnología e ingeniería, que se va extendiendo rápidamente al resto de disciplinas científicas. El principal objetivo del proyecto es incorporar de forma beneficiosa la tecnología y utilizarla al servicio del aprendizaje. En un entorno de aprendizaje que requiere capacidad de juicio y de pensamiento crítico para la de toma de decisiones, es importante hacer partícipes a los profesores en la búsqueda de sus necesidades no resueltas y la adopción de posibles soluciones, utilizando la tecnología más moderna. Además, también en una sociedad que avanza a una velocidad imparable en el ámbito digital, facilitar el acceso a información de forma global, beneficia no sólo a los alumnos, sino también a los profesores, y aporta valor añadido a la Universidad Complutense de Madrid. Tras la experiencia del confinamiento en la etapa Covid19 y el teletrabajo la asistencia virtual es una necesidad. La originalidad del Proyecto estriba precisamente en el planteamiento de la incorporación de la asistencia virtual e inteligencia artificial para la asistencia y apoyo a los profesores. En el ámbito europeo es cada vez mayor la preocupación por el uso y aplicaciones de la tecnología. Por ello, en primer lugar, es importante detectar las necesidades reales de los profesores, las lagunas de información y las dificultades para encontrarla, habilitando encuestas y grupos de trabajo, y profundizar sobre las cuestiones de interés a juicio de todos los implicados
