Experiencias de Docencia Virtual en Facultades de Medicina Españolas durante la pandemia COVID-19 (II): Farmacología, Inmunología.
We present a summary of the activities that some professors of Schools of Medicine of Spain have carried out during the 3 weeks prior to spring break. During that time, due to COVID-19, face-to-face teaching had to be replaced by online or virtual activities, due to the implementation of the state of alarm in Spain, which led to the complete closure of the Universities since March 13, 2020. The experiences are from Pharmacology and Immunology.Presentamos un resumen de las actividades que algunos profesores de Facultades de Medicina españolas han llevado a cabo durante las 3 semanas previas a las vacaciones de primavera. Durante este tiempo, debido a la pandemia provocada por la COVID-19, la docencia presencial tuvo que ser sustituída por actividades en línea o virtuales, a causa de la implantación del estado de alarma en España que motivó el cierre completo de las Universidades desde el 13 de marzo de 2020. Las experiencias son de Farmacología y de Inmunología
Incorporación de la Web 2.0 en la docencia de Proyectos e Infraestructuras de Telecomunicación II: Curso de adaptación al grado
Comunicación y póster presentados en las IX Jornadas de Redes de Investigación en Docencia Universitaria, Alicante, 16-17 junio 2011.La llegada de las nuevas titulaciones de Grado en la UA ha favorecido la implantación de un Curso de adaptación al Grado en Ingeniería en Sonido e Imagen, orientado a los ya titulados en Ingeniería Técnica de Telecomunicación, especialidad en Sonido e Imagen. La mayoría de este alumnado está interesado en compaginar su horario laboral y el calendario lectivo. Aunque en muchos casos es una tarea complicada. Por ello, en la asignatura de Proyectos e Infraestructuras en Telecomunicación II se han recurrido a diversas herramientas Web colaborativas: Google Apps y Moodle. Estas herramientas y su aplicación han servido para facilitar la comunicación entre el profesorado y el estudiante, a través del trabajo colaborativo y la realimentación entre ambas partes ya que permiten entre otras actividades compartir documentos, entrega de trabajos online, realización y autocorrección de test, chat entre los miembros de la plataforma y una temporización a priori bastante precisa. También se ha recurrido a ciertas aplicaciones libres basadas en navegador para facilitar el trabajo a distancia, permitiendo a los estudiantes trabajar desde cualquier PC con acceso a Internet. La aplicación de estas herramientas ha favorecido el proceso de enseñanza aprendizaje significativamente a aquellos estudiantes con incompatibilidades horarias.Este trabajo ha sido financiado por el Vicerrectorado de Tecnología e Innovación Educativa de la Universidad de Alicante (proyecto GITE-09006-UA y proyecto GITE-09014-UA)
Candelilla wax edible coating with Flourensia cernua bioactives to prolong the quality of tomato fruits
The improvement of the postharvest quality of tomato fruits was evaluated using an edible coating functionalized with an Flourensia cernua extract evaluating the antifungal, structural, barrier, and optical properties. The formulation and evaluation of an edible coating and its application on tomato was evaluated using a response surface methodology to determine the ideal concentrations of candelilla wax, whey protein, and glycerol. Edible films showed good barrier properties, with water vapor permeability varying from 0.4350.404 g mm/m2 day kPa. The addition o F. cernua extract showed significant improvement in the transparency of films. The edible coating applied to tomato reduced weight and firmness loss. The sensory evaluation proved that the product obtained is acceptable for consumers. The edible coating added with F. cernua extract was the most effective in inhibiting the growth of pathogenic fungi and the visual appearance at the end of storage confirmed the beneficial effect of the edible coating.(undefined)info:eu-repo/semantics/publishedVersio
Standardization in laboratory medicine: Two years’ experience from category 1 EQA programs in Spain
Introduction: Standardization is the ability to obtain interchangeable results leading to same medical interpretation. External quality assessment
(EQA) is the main support of the on-going harmonization initiatives. Aim of study was to evaluate results obtained from two years category 1 EQA
program experience in Spain and determine the impact of applying this type of EQA program on the analytical standardization.
Materials and methods: According to the analytical method, traceability and instrument different groups were established which results were
evaluated by calculating mean, coefficient of variation and percent of deviation to the reference value. Analytical performance specifications used
to the results\u27 evaluation were derived from biological variation for bias and from the inter-laboratory coefficients of variation found in a previous
pilot study.
Results: Only creatinine measured by enzymatic methods gave excellent results, although few laboratories used this method. Creatine kinase and
GGT gave good precision and bias in all, but one instrument studied. For the remaining analytes (ALT, ALP, AST, bilirubin, calcium, chloride, glucose,
magnesium, potassium, sodium, total protein and urate) some improvement is still necessary to achieve satisfactory standardization in our setting.
Conclusions: The two years of category 1 EQA program experience in Spain have manifested a lack of standardization of 17 most frequent biochemistry
tests used in our laboratories. The impact of the information obtained on the lack of standardization is to recommend abandoning methods
such as ALT, AST without exogenous pyridoxal phosphate, Jaffe method for creatinine, and do not use non-commutable calibrators, such as aqueous
solutions for calcium and sodium
Measurement of the cross-section and charge asymmetry of bosons produced in proton-proton collisions at TeV with the ATLAS detector
This paper presents measurements of the and cross-sections and the associated charge asymmetry as a
function of the absolute pseudorapidity of the decay muon. The data were
collected in proton--proton collisions at a centre-of-mass energy of 8 TeV with
the ATLAS experiment at the LHC and correspond to a total integrated luminosity
of 20.2~\mbox{fb^{-1}}. The precision of the cross-section measurements
varies between 0.8% to 1.5% as a function of the pseudorapidity, excluding the
1.9% uncertainty on the integrated luminosity. The charge asymmetry is measured
with an uncertainty between 0.002 and 0.003. The results are compared with
predictions based on next-to-next-to-leading-order calculations with various
parton distribution functions and have the sensitivity to discriminate between
them.Comment: 38 pages in total, author list starting page 22, 5 figures, 4 tables,

Search for chargino-neutralino production with mass splittings near the electroweak scale in three-lepton final states in √s=13 TeV pp collisions with the ATLAS detector
A search for supersymmetry through the pair production of electroweakinos with mass splittings near the electroweak scale and decaying via on-shell W and Z bosons is presented for a three-lepton final state. The analyzed proton-proton collision data taken at a center-of-mass energy of √s=13 TeV were collected between 2015 and 2018 by the ATLAS experiment at the Large Hadron Collider, corresponding to an integrated luminosity of 139 fb−1. A search, emulating the recursive jigsaw reconstruction technique with easily reproducible laboratory-frame variables, is performed. The two excesses observed in the 2015–2016 data recursive jigsaw analysis in the low-mass three-lepton phase space are reproduced. Results with the full data set are in agreement with the Standard Model expectations. They are interpreted to set exclusion limits at the 95% confidence level on simplified models of chargino-neutralino pair production for masses up to 345 GeV
Patients receiving a high burden of antibiotics in the community in Spain: a cross-sectional study.
Some patients in the community receive a high burden of antibiotics. We aimed at describing the characteristics of these patients, antibiotics used, and conditions for which they received antibiotics. We carried out a cross-sectional study. Setting: Thirty Health Primary Care Areas from 12 regions in Spain, covering 5,960,191 inhabitants. Patients having at least 30 packages of antibacterials for systemic use dispensed in 2017 were considered. Main outcome measures: Prevalence of antibiotic use, conditions for which antibiotics were prescribed, clinical characteristics of patients, comorbidities, concomitant treatments, and microbiological isolates. Patient's average age was 70 years; 52% were men; 60% smokers/ex-smokers; 54% obese. Overall, 93% of patients had, at least, one chronic condition, and four comorbidities on average. Most common comorbidities were cardiovascular and/or hypertension (67%), respiratory diseases (62%), neurological/mental conditions (32%), diabetes (23%), and urological diseases (21%); 29% were immunosuppressed, 10% were dead at the time of data collection. Patients received three antibiotic treatments per year, mainly fluoroquinolones (28%), macrolides (21%), penicillins (19%), or cephalosporins (12%). Most frequently treated conditions were lower respiratory tract (infections or prophylaxis) (48%), urinary (27%), and skin/soft tissue infections (11%). Thirty-five percent have been guided by a microbiological diagnosis, being Pseudomonas aeruginosa (30%) and Escherichia coli (16%) the most frequent isolates. In conclusion, high antibiotic consumers in the community were basically elder, with multimorbidity and polymedication. They frequently received broad-spectrum antibiotics for long periods of time. The approach to infections in high consumers should be differentiated from healthy patients receiving antibiotics occasionally
