    Improving Motivation And Continuous Assessment In Engineering Classrooms Through Student Response Systems

    The use of Student Response Systems (SRS) is highly recommended to encourage the active and meaningful learning of students in each lecture. SRS promotes the motivation of students and improves the system of continuous assessment. One of the most popular applications designed for SRS is Socrative (Socrative n.d.). The use of Socrative gives real meaning to continuous assessment, since the teacher has an easily manageable record of the evolution of their students‘learning and will help the teacher to schedule both formative and summative assessment. The application allows the detection of topics that each student may not have understood and determines the percentage of the entire class with the same difficulty. Beyond the use of Socrative as an evaluation instrument, sufficiently referenced, in this article we present different methodologies supported by SRS implemented in engineering studies at the University the Salamanca. The methodologies aim to promote autonomous work outside the classroom, and in face-to-face classes, to maintain the attention and lead the reasoning of the students to facilitate learning. The influence of the methodologies proposed by the authors on a series of indicators related to the motivation and commitment of the students to the subjects will be presented. To the best of our knowledge, most of the work on SRS have been applied to non-university educational levels and for assessment purposes and very few of them have applied SRS to undergraduate engineering studies. The novelty of this work lies in introducing new methodologies supported by SRS in university engineering studies

    Herbs as an Active Ingredient in Sport: Availability and Information on the Internet

    [EN] The use of supplements containing herbal active ingredients in sport has increased in recent years. Their consumption is explained by the benefits they may provide and because their natural origin do not involve health complications, from the point of view of the consumers. The aim of this study is to analyze the availability of four supplements (caffeine, turmeric, ginseng, cannabidiol) on the internet and understand the nature of these websites. A descriptive, observational, and cross-sectional study design was used. A detailed search was carried out with specifically developed software. The searches and data evaluation took 10 days. The websites consulted correspond to those that sell supplements, or some sport websites in the case of the Spanish ones, whereas those in English belong to pharmacies, parapharmacies, or herbalists. It is concluded that the websites do not provide adequate information to ensure proper consumption and lack advice on the choices of supplements and their administration guidelinesS

    Final results of this work have been presented at the following meetings: 36rd Annual Meeting of the European Society for Pediatric Infectious Diseases (ESPID 2018), Malmö, Sweden, 28th May-June 2nd, 2018. (Ref. ESP18-0517).Aims: Vaccine response is poor among children living with HIV. The gut microbiota has been identified as a potential target to improve vaccine immunogenicity, but data are scarce in the context of HIV infection. Methods: Pilot, double-blind, randomized placebo-controlled trial in which 24 HIV-infected children were randomized to receive a mixture of symbiotics, omega-3/6 fatty acids, and amino acids or placebo for 4 weeks, each in combination with ART, and were then immunized against influenza. Vaccine response and safety of the nutritional supplementation were the primary outcomes. Results: Eighteen HIV-infected children completed the follow-up period (mean age 11.5 ± 4.14 years, 61% female). The nutritional supplement was safe but did not enhance the response to the influenza vaccine. A 4-fold rise in antibody titers was obtained in only 37.5% of participants in the intervention arm vs. 40% in the placebo. No immunological or inflammatory predictors of vaccine response were identified. Conclusions: In this exploratory study, a 4-week course of symbiotics did not increase influenza vaccine immunogenicity in HIV-infected children. Larger studies are warranted to address the potential of modulating the microbiome in children living with HIV.This work was funded by the Instituto de Salud Carlos III-Fondos FEDER (grant number CB21/17/00025), Acción Estratégica en Salud (PI13/0422, PI17/01283, PI18/00154, and PI18CIII/00009).
