Agile human centered methodologies to develop educational software

This paper presents a methodological proposal that is based on powerful current approaches to the software development process: agile methodologies (SCRUM, Lean UX), user-centered design (UCD) and user experience design (UXD). Specifically, we have adapted some of the characteristics of the agile methodologies, which have allowed us to produce useful prototypes that are focused on the users while receiving constant feedback from them. The main goal of the proposed methodology is to identify usability problems and UX factors in the early stages of educational software development. Furthermore, we have also applied and validated the proposal during the framework development of an educational software project for users with special educational needs. A specific case taking into account key usability issues to support students with special education needs (SEN) is presented. In conclusion, we state that the proposed methodology could be a good design process philosophy to follow in the development of software projects in general, and in educational projects in particular

Health Promotion for Childhood Obesity: An Approach Based on Self-Tracking of Data

[EN]At present, obesity and overweight are a global health epidemic. Traditional interventions for promoting healthy habits do not appear to be e ective. However, emerging technological solutions based on wearables and mobile devices can be useful in promoting healthy habits. These applications generate a considerable amount of tracked activity data. Consequently, our approach is based on the quantified-self model for recommending healthy activities. Gamification can also be used as a mechanism to enhance personalization, increasing user motivation. This paper describes the quantified-self model and its data sources, the activity recommender system, and the PROVITAO App user experience model. Furthermore, it presents the results of a gamified program applied for three years in children with obesity and the process of evaluating the quantified-self model with experts. Positive outcomes were obtained in children’s medical parameters and health habits

Improving Cognitive Visual-Motor Abilities in Individuals with Down Syndrome

Down syndrome causes a reduction in cognitive abilities, with visual-motor skills being particularly affected. In this work, we have focused on this skill in order to stimulate better learning. The proposal relies on stimulating the cognitive visual-motor skills of individuals with Down Syndrome (DS) using exercises with a gestural interaction platform based on the KINECT sensor named TANGO:H, the goal being to improve them. To validate the proposal, an experimental single-case study method was designed using two groups: a control group and an experimental one, with similar cognitive ages. Didactic exercises were provided to the experimental group using visual cognitive stimulation. These exercises were created on the TANGO:H Designer, a platform that was designed for gestural interaction using the KINECT sensor. As a result, TANGO:H allows for visual-motor cognitive stimulation through the movement of hands, arms, feet and head. The “Illinois Test of Psycholinguistic Abilities (ITPA)” was applied to both groups as a pre-test and post-test in its four reference sections: visual comprehension, visual-motor sequential memory, visual association, and visual integration. Two checks were made, one using the longitudinal comparison of the pre-test/post-test of the experimental group, and another that relied on comparing the difference of the means of the pre-test/post-test. We also used an observational methodology for the working sessions from the experimental group. Although the statistical results do not show significant differences between the two groups, the results of the observations exhibited an improvement in visual-motor cognitive skills

Patient 9 years old with a diagnosis of Cutaneous Leishmaniasis Located in the Abdominal Region. Case Report

Las leishmaniasis es un grupo de enfermedades infecciosas ocasionadas por el protozoario del género Leishmania spp., el cual tiene la facultad de infectar el sistema reticuloendotelial de los macrófagos. Esta se transmite mediante un vector, los mosquitos del género Phlebotomus y Lutzomyia, con aproximadamente 30 especies documentadas. El reservorio son los mamíferos salvajes y domésticos, algunas veces de forma asintomática, y otras cursando con manifestaciones clínicas evidentes como es el caso en los humanos. Las principales formas clínicas son la visceral, la mucocutánea y la cutánea. El diagnóstico es difícil por la inespecificidad de la clínica y el lento crecimiento del parásito en cultivo. Existen distintas opciones terapéuticas, por lo que cada caso debe ser valorado individualmente según las características de la lesión, la especie causante y el potencial de afectación mucosa. En nuestro país, la primera línea de tratamiento está constituida por los antimoniales pentavalentes intralesionales. Paciente de 9 años que acude junto a su madre por presentar desde hace 1 meses, tres lesiones ulcerosas localizadas en región abdominal, de aproximadamente 3 x 4 cm, acompañadas con presencia de líquido purulento motivo por el cual acude.Leishmaniasis is a group of infectious diseases caused by the protozoan of the genus Leishmania spp., which has the ability to infect the reticuloendothelial system of macrophages. This is transmitted through a vector, mosquitoes of the genus Phlebotomus and Lutzomyia, with approximately 30 documented species. The reservoir is wild and domestic mammals, sometimes asymptomatic, and other times presenting with obvious clinical manifestations, as is the case in humans. The main clinical forms are visceral, mucocutaneous and cutaneous. Diagnosis is difficult due to the nonspecificity of the symptoms and the slow growth of the parasite in culture. There are different therapeutic options, so each case must be evaluated individually according to the characteristics of the lesion, the causative species and the potential for mucosal involvement. In our country, the first line of treatment consists of intralesional pentavalent antimonials. A 9-year-old patient who comes with his mother because he has had three ulcerative lesions located in the abdominal region for 1 month, measuring approximately 3 x 4 cm, accompanied by the presence of purulent fluid, which is why he comes

RBD-specific polyclonal F(ab´)2 fragments of equine antibodies in patients with moderate to severe COVID-19 disease: A randomized, multicenter, double-blind, placebo-controlled, adaptive phase 2/3 clinical trial

Background: passive immunotherapy is a therapeutic alternative for patients with COVID-19. Equine polyclonal antibodies (EpAbs) could represent a source of scalable neutralizing antibodies against SARS-CoV-2. Methods: we conducted a double-blind, randomized, placebo-controlled trial to assess efficacy and safety of EpAbs (INM005) in hospitalized adult patients with moderate and severe COVID-19 pneumonia in 19 hospitals of Argentina. Primary endpoint was improvement in at least two categories in WHO ordinal clinical scale at day 28 or hospital discharge (ClinicalTrials.gov number NCT04494984). Findings: between August 1st and October 26th, 2020, a total of 245 patients were enrolled. Enrolled patients were assigned to receive two blinded doses of INM005 (n = 118) or placebo (n = 123). Median age was 54 years old, 65 1% were male and 61% had moderate disease at baseline. Median time from symptoms onset to study treatment was 6 days (interquartile range 5 to 8). No statistically significant difference was noted between study groups on primary endpoint (risk difference [95% IC]: 5 28% [-3 95; 14 50]; p = 0 15). Rate of improvement in at least two categories was statistically significantly higher for INM005 at days 14 and 21 of follow-up. Time to improvement in two ordinal categories or hospital discharge was 14 2 (§ 0 7) days in the INM005 group and 16 3 (§ 0 7) days in the placebo group, hazard ratio 1 31 (95% CI 1 0 to 1 74). Subgroup analyses showed a beneficial effect of INM005 over severe patients and in those with negative baseline antibodies. Overall mortality was 6 9% the INM005 group and 11 4% in the placebo group (risk difference [95% IC]: 0 57 [0 24 to 1 37]). Adverse events of special interest were mild or moderate; no anaphylaxis was reported. Interpretation: Albeit not having reached the primary endpoint, we found clinical improvement of hospitalized patients with SARS-CoV-2 pneumonia, particularly those with severe disease.Fil: Lopardo, Gustavo.
