El diseño de materiales educativos digitales : Una mirada desde los estudiantes usuarios

El acceso a la información empleando tecnología cada vez más avanzada es un fenómeno social que abarca hasta las poblaciones más apartadas y de distinto nivel socioeconómico. El uso de los dispositivos móviles y los nuevos sistemas de acceso al conocimiento, como la realidad aumentada y los códigos QR permitirían enriquecer los contenidos textuales con diferentes medios: videos, juegos, actividades y material interactivo y poder acceder a los mismos desde cualquier lugar. Nuestro objetivo es mostrar el diseño de contenidos utilizando estas tecnologías como así también la evaluación de dichos materiales por parte de los alumnos en el Curso semipresencial de Ingreso a la Facultad de Ciencias Naturales e IML (UNT). Para su confección se realizaron análisis bibliográficos, recopilación de material multimedial adecuado, software de diseño y software de generación de código QR. Para la evaluación del material por parte de los alumnos, se utilizaron las respuestas a una encuesta de evaluación general del curso. Consideramos que este material utiliza nuevos paradigmas de aprendizaje y contribuye a la motivación y la adquisición de competencias tecnológicas, tan importantes en el inicio de una carrera universitaria, a la vez que posibilita el acceso de los alumnos de un amplio rango de condiciones socio-culturales que aspiran iniciar una carrera universitaria.Eje 2 - Mesa 2.Dirección de Educación a Distancia, Innovación en el aula y TIC (EAD

Treatment with tocilizumab or corticosteroids for COVID-19 patients with hyperinflammatory state: a multicentre cohort study (SAM-COVID-19)

Objectives: The objective of this study was to estimate the association between tocilizumab or corticosteroids and the risk of intubation or death in patients with coronavirus disease 19 (COVID-19) with a hyperinflammatory state according to clinical and laboratory parameters. Methods: A cohort study was performed in 60 Spanish hospitals including 778 patients with COVID-19 and clinical and laboratory data indicative of a hyperinflammatory state. Treatment was mainly with tocilizumab, an intermediate-high dose of corticosteroids (IHDC), a pulse dose of corticosteroids (PDC), combination therapy, or no treatment. Primary outcome was intubation or death; follow-up was 21 days. Propensity score-adjusted estimations using Cox regression (logistic regression if needed) were calculated. Propensity scores were used as confounders, matching variables and for the inverse probability of treatment weights (IPTWs). Results: In all, 88, 117, 78 and 151 patients treated with tocilizumab, IHDC, PDC, and combination therapy, respectively, were compared with 344 untreated patients. The primary endpoint occurred in 10 (11.4%), 27 (23.1%), 12 (15.4%), 40 (25.6%) and 69 (21.1%), respectively. The IPTW-based hazard ratios (odds ratio for combination therapy) for the primary endpoint were 0.32 (95%CI 0.22-0.47; p < 0.001) for tocilizumab, 0.82 (0.71-1.30; p 0.82) for IHDC, 0.61 (0.43-0.86; p 0.006) for PDC, and 1.17 (0.86-1.58; p 0.30) for combination therapy. Other applications of the propensity score provided similar results, but were not significant for PDC. Tocilizumab was also associated with lower hazard of death alone in IPTW analysis (0.07; 0.02-0.17; p < 0.001). Conclusions: Tocilizumab might be useful in COVID-19 patients with a hyperinflammatory state and should be prioritized for randomized trials in this situatio

Perfiles de apropiación de TIC y desempeño académico en estudiantes universitarios. Un estudio de caso utilizando analítica del aprendizaje

Today's society constantly demands solutions to complex problems; in many cases, the solution’s searching processes do not fit in the traditional cognitive processes. In the framework of digital culture, it is necessary to update the knowledge of education professionals in disruptive methodologies. The article presents design thinking as an alternative approach for the planning and developing of a training device for higher-level non-university teachers. The strategies to design and prototype the device are detailed as well as the evaluative research that was the starting point to generate innovation based on the users’ needs.En el presente trabajo se utilizarán analíticas del aprendizaje sobre los estudiantes y sus contextos como apoyo a la docencia y a la mejora de los procesos de enseñanza-aprendizaje desde una aproximación no “maximalista”.  Se tendrán en cuenta las prácticas efectivas de los sujetos con el fin de  identificar perfiles de apropiación de tecnología de la información y la comunicación (TIC) por parte de los estudiantes, a partir sus huellas digitales en el aula virtual, combinado con datos cuantitativos del rendimiento académico y las propias opiniones de los usuarios.

NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the Neotropics

Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal species that (1) transposed a geographical barrier and (2) were voluntarily or involuntarily introduced by humans into the Neotropics. Our data set is composed of 73,738 historical and current georeferenced records on alien mammal species of which around 96% correspond to occurrence data on 77 species belonging to eight orders and 26 families. Data cover 26 continental countries in the Neotropics, ranging from Mexico and its frontier regions (southern Florida and coastal-central Florida in the southeast United States) to Argentina, Paraguay, Chile, and Uruguay, and the 13 countries of Caribbean islands. Our data set also includes neotropical species (e.g., Callithrix sp., Myocastor coypus, Nasua nasua) considered alien in particular areas of Neotropics. The most numerous species in terms of records are from Bos sp. (n = 37,782), Sus scrofa (n = 6,730), and Canis familiaris (n = 10,084); 17 species were represented by only one record (e.g., Syncerus caffer, Cervus timorensis, Cervus unicolor, Canis latrans). Primates have the highest number of species in the data set (n = 20 species), partly because of uncertainties regarding taxonomic identification of the genera Callithrix, which includes the species Callithrix aurita, Callithrix flaviceps, Callithrix geoffroyi, Callithrix jacchus, Callithrix kuhlii, Callithrix penicillata, and their hybrids. This unique data set will be a valuable source of information on invasion risk assessments, biodiversity redistribution and conservation-related research. There are no copyright restrictions.

Evaluation of a quality improvement intervention to reduce anastomotic leak following right colectomy (EAGLE): pragmatic, batched stepped-wedge, cluster-randomized trial in 64 countries

Background Anastomotic leak affects 8 per cent of patients after right colectomy with a 10-fold increased risk of postoperative death. The EAGLE study aimed to develop and test whether an international, standardized quality improvement intervention could reduce anastomotic leaks. Methods The internationally intended protocol, iteratively co-developed by a multistage Delphi process, comprised an online educational module introducing risk stratification, an intraoperative checklist, and harmonized surgical techniques. Clusters (hospital teams) were randomized to one of three arms with varied sequences of intervention/data collection by a derived stepped-wedge batch design (at least 18 hospital teams per batch). Patients were blinded to the study allocation. Low- and middle-income country enrolment was encouraged. The primary outcome (assessed by intention to treat) was anastomotic leak rate, and subgroup analyses by module completion (at least 80 per cent of surgeons, high engagement; less than 50 per cent, low engagement) were preplanned. Results A total 355 hospital teams registered, with 332 from 64 countries (39.2 per cent low and middle income) included in the final analysis. The online modules were completed by half of the surgeons (2143 of 4411). The primary analysis included 3039 of the 3268 patients recruited (206 patients had no anastomosis and 23 were lost to follow-up), with anastomotic leaks arising before and after the intervention in 10.1 and 9.6 per cent respectively (adjusted OR 0.87, 95 per cent c.i. 0.59 to 1.30; P = 0.498). The proportion of surgeons completing the educational modules was an influence: the leak rate decreased from 12.2 per cent (61 of 500) before intervention to 5.1 per cent (24 of 473) after intervention in high-engagement centres (adjusted OR 0.36, 0.20 to 0.64; P &lt; 0.001), but this was not observed in low-engagement hospitals (8.3 per cent (59 of 714) and 13.8 per cent (61 of 443) respectively; adjusted OR 2.09, 1.31 to 3.31). Conclusion Completion of globally available digital training by engaged teams can alter anastomotic leak rates. Registration number: NCT04270721 (http://www.clinicaltrials.gov)
