- Abstract
Surgical site infections (SSIs), mainly caused by Staphylococcus aureus , pose a significant economic burden in Europe, leading to increased hospitalization duration, mortality, and treatment costs, particularly with drug-resistant strains such as meticillin-resistant S. aureus. To conduct a case–control study on the economic impact of S. aureus SSI in adult surgical patients across high-volume centres in France, Germany, Spain, and the UK, aiming to assess the overall and procedure-specific burden across Europe. The SALT study is a multinational, retrospective cohort study with a nested case–control analysis focused on S. aureus SSI in Europe. The study included participants from France, Germany, Italy, Spain, and the UK who underwent invasive surgery in 2016 and employed a micro-costing approach to evaluate health economic factors, matching S. aureus SSI cases with controls. In 2016, among 178,904 surgical patients in five European countries, 764 developed S. aureus SSI. Matching 744 cases to controls, the study revealed that S. aureus SSI cases incurred higher immediate hospitalization costs (€8,810), compared to controls (€6,032). Additionally, S. aureus SSI cases exhibited increased costs for readmissions within the first year post surgery (€7,961.6 versus €5,298.6), with significant differences observed. Factors associated with increased surgery-related costs included the cost of hospitalization immediately after surgery, first intensive care unit (ICU) admission within 12 months, and hospital readmission within 12 months, as identified through multivariable analysis. The higher rates of hospitalization, ICU admissions, and readmissions among S. aureus SSI cases highlight the severity of these infections and their impact on healthcare costs, emphasizing the potential benefits of evidence-based infection control measures and improved patient care to mitigate the economic burden.

- Abstract
Collaborative design approaches have been increasingly adopted in the design of learning technologies since they contribute to develop pedagogically inclusive and appropriate learning designs. Despite the positive reception of collaborative design strategies in technology-enhanced learning, little attention has been dedicated to analyzing the challenges faced in design processes using a collaborative approach. In this paper, we disclose the collaborative design of a chatbot for self-regulated learning in higher education using an action research approach. We analyze the design process of EDUguia chatbot, which includes diverse evidence from questionnaires and workshops with students and lecturers, as well as intermediary design objects. Based on the qualitative analysis, we identify several challenges that are transversal to the co-design work, as well as specific to the design phases. We critically reflect on the strategies deployed to overcome these challenges and how they relate to decision-making processes, highlighting the need to make stakeholders’ tacit knowledge explicit, cultivate trust-building and support democratic decision-making in technology design processes. We believe that the recommendations we present in this paper contribute to developing best practices in the collaborative design of chatbots for the self-regulation of learning, as well as learning technology in general.

- Abstract
[EN] During the last years Massive Open Online Courses as a new learning modality have generated defenders and detractors based on different parameters such as their pedagogical design or the type of assessment they implement. In this sense, MOOCs may possess certain characteristics that cause certain potentialities or benefits or certain difficulties or limitations to be attributed to them. The following work aims to explore the advantages and disadvantages -from the point of view of students, lecturers and higher education institutions- of this open education modality and to determine what is their role in the framework of online education. To this end, the results of open and closed questionnaires administered to educational technology teachers, to MOOC experts and to university students in the Spanish context are analysed. After confirming the results presented, possible reflections on the need to continue research within the framework of Massive Open Online Courses are taken. In this sense, future studies could deepen into how the elements that have appeared as the most determinant (flexible and lifelong learning, autonomous learning, teacher reputation, visibility and publicity of knowledge, accreditation of learning, etc.) within the framework of the new massive and open online courses could favour the functioning of this new model of distance education and the improvement of the assessment of learning in its context (one of MOOC greatest limitation)., [ES] Los cursos en línea masivos y abiertos como nueva modalidad formativa han generado defensores y detractores en función de distintos parámetros como su diseño o el tipo de evaluación que implementan. En este sentido, los MOOC pueden poseer ciertas características que hacen que se les atribuyan ciertas potencialidades o beneficios, o ciertas dificultades o limitaciones. El trabajo que se presenta tiene el objetivo de explorar las ventajas y las desventajas de esta modalidad de educación abierta -des del punto de vista de los estudiantes, los profesores y las instituciones de educación superior- y determinar cuál es su papel en el marco de la educación en línea. Para ello se analizan los resultados de cuestionarios abiertos y cerrados administrados a profesores de tecnología educativa, expertos en MOOC y estudiantes universitarios del contexto español. A partir de constatar los resultados presentados se extraen posibles reflexiones sobre la necesidad de continuar la investigación en el marco de los MOOC. En este sentido, futuros estudios podrían profundizar en cómo los elementos que han aparecido más determinantes en el marco de los nuevos cursos en línea masivos y abiertos (el aprendizaje flexible y a lo largo de la vida, el aprendizaje autónomo, la reputación docente, la visibilidad y publicidad de los conocimientos, la acreditación de los aprendizajes, etcétera) podrían favorecer el funcionamiento de este nuevo modelo de educación a distancia y la mejora de la evaluación de los aprendizajes en su contexto, su mayor limitación.

[EN] The paper presented here is part of the research project “The education assessment impact on the competence development in the university. Perspectives from the new graduates groups” (reference EDU2012-32766), which, since 2012, involves seven Spanish universities in four of their degrees: primary education, pharmacy, computer science and electrical engineering. This study has the aim of analysing the impact of educational assessment in developing competencies in higher education from the perception of the first graduates groups formed under the new European Higher Education Area, through a predominantly qualitative methodology mainly based on life stories, interviews and focus groups. Concretely, this paper presents the analysis of the results of one phase of the study based on the life stories of the old diploma holders and of the first graduating groups that studied under the curricula developed for the EHEA. Through a constant comparison between the points of view of these participants, the following paper focuses on four key dimensions for improving the future of higher education: a) What competencies are being acquired at the university? b) What is the relationship between the acquisition of these competencies and the methodologies carried out? c) What is the relationship between the acquisition of these competencies and the educational assessment carried out? d) What do the non-formal and informal contexts bring for the competencies development? The results show that most perceived developed competencies are instrumental kind and that they are linked to cases and project based work but they are not strongly linked to the assessment strategies and tools. Moreover, labor contexts seem to be very important in skills development, according to participants [ES] El trabajo que se presenta a continuación forma parte del proyecto de investigación “El impacto de la evaluación educativa en el desarrollo de competencias en la universidad. La perspectiva de la primeras promociones de graduados ” (referencia EDU2012-32766), en el que, desde 2012, participan siete universidades españolas con cuatro de sus titulaciones: educación primaria, farmacia, ingeniería informática e ingeniería electrónica industrial. El estudio nace con el objetivo de analizar el impacto de la evaluación educativa en el desarrollo de competencias en la universidad a partir de la percepción de las primeras promociones de graduados formados en el marco del Espacio Europeo de Educación Superior a través de una metodología eminentemente cualitativa basada principalmente en los relatos, las entrevistas y los grupos de discusión. Este artículo presenta el análisis de los resultados de una fase de la investigación, a partir de relatos abiertos de, por un lado, los diplomados, licenciados o ingenieros de las antiguas titulaciones, y por otro lado, de los nuevos graduados universitarios. A través de una comparación constante entre las opiniones de dichos participantes, el siguiente trabajo profundiza sobre cuatro dimensiones clave para la mejora del futuro de la formación universitaria: a) ¿qué competencias se adquieren en la carrera?; b) ¿cuál es la relación existente entre la adquisición de dichas competencias y las metodologías llevadas a cabo?; c) ¿cuál es la relación existente entre la adquisición de dichas competencias y las evaluaciones practicadas? y d) ¿qué aportan los contextos no formales e informales al desarrollo de competencias? Los resultados muestran que se percibe un mayor desarrollo de las competencias instrumentales y que se vinculan al trabajo por proyectos y casos prácticos pero no a las estrategias e instrumentos de evaluación. Por otra parte, los contextos laborales parecen tener un gran peso en el desarrollo competencial, a juicio de los participantes.

Objetivo: el Helicobacter pylori irrumpió en el ámbito médico-gastroenterológico, revolucionándo la fisiopatología y el tratamiento de la Ulcera Gastroduodenal. Esta infestación trae consigo una respuesta inmune, que se puede reconocer con las pruebas serológicas, las cuales son muy útiles en el reconocimiento de la infección, sobre todo entre los grupos de riesgo, tales como son las personas institucionalizados y el personal sanitario y, entre estos, principalmente los trabajadores de los Departamentos de Gastroenterología. Método: en el presente artículo realizamos un estudio prospectivo longitudinal en 38 trabajadores de los Departamentos de Gastroenterología de tres hospitales de Ciudad de La Habana, tomando como controles a 38 trabajadores de un hospital que no desempeñan actividad endoscópica digestiva. Pretendemos investigar la presencia entre ellos de anticuerpos contra el H. pylori. El personal analizado completó una encuesta diseñada al efecto y se consideraron los siguientes parámetros: edad, sexo, tiempo de trabajo como endoscopista, uso de medios de protección y antecedentes de patología gastroduodenal. Resultados: nuestro grupo de investigación constaba de 38 endoscopistas y 38 trabajadores de un centro asistencial, ajenos a esta actividad laboral, que presentaba las mismas características socioeconómicas que el grupo investigado. Veinticuatro en ambos grupos eran mujeres, (63,16%) y 14 eran hombres (36,84%). El 39,47% de los endoscopistas fueron seropositivos mientras que esto ocurrió sólo en el 7,89% de los controles. Se analizó el tiempo que los endoscopistas llevaban en el trabajo y encontramos que los seropositivos llevaban más tiempo trabajando como endoscopistas que los seronegativos. Conclusiones: se demostró que los endoscopistas tienen un riesgo significativamente superior a los controles de infestarse por el Helicobacter pylori, y que los endoscopistas seropositivos presentaron sintomatología más frecuentemente que los seronegativos, aunque las diferencias no fueron estadísticamente significativas. Objective: the Helicobacter pylori entered into the medical world, particularly in the field of the Gastroenterology, revolutionizing it, and changing partially our physiopathological concepts and treatment of the gastroduodenal ulcer. This infestation results in an immune response, that is measured by means of serologic tests, which are very useful in the massive screening studies, mainly in population at risk like those who are institutionalized and the personnel of health, particularly workers of the departments of Gastroenterology. Method:motivated for this, we carry out a prospective study in 38 endoscopists using as controls 38 workers not related with a Gastroenterology department. Thus, we analyzed the presence of antibodies against Helicobacter pylori among the personnel of the departments of Gastroenterology of three hospitals of Havana City. These personnel filled a form designed for this purpose containing following data: age, sex, time of work as endoscopist, use of protection means, and history of gastroduodenal pathology. Results: there were 24 women in each group (63,2%). Whereas the seroprevalence among endoscopists was 39,47%, in the control group, only three people were seropositives (7,89%). We found a positive correlation between the time working as endoscopists and the rate of seropositivity. Conclusions: our study demonstrated that endoscopists have a significantly higher risk than the controls of contracting the infection by the Helicobacter pylori, and that the seropositive endoscopists have sintomatology more frequently than the seronegative endoscopists, although these differences were not statistically significant.

- Abstract
In a study conducted in the province of Cienfuegos, it was proved by using immunological and biomolecular tools that intestina amebiasis in that province was an overdimensioned health problem. A survey on knowledge, perceptions and practices applied to those physicians related to the diagnosis, treatment and control of this parasitosis showed that the overdimensioning may be associated with an inadequate perception of the problem and with a marked lack of knowledge about important aspects of this entity. To contribute to the solution of the ovedimensioning and of its consequences, a set of actions were taken in that province. After a year, a second survey was done, whose results are published in this document, allowing to know about a significant improvement of the surveyed in almost all the evaluated cognitive and perceptual aspects (6.73 and 11.23 means of correct answers before and after the intervention, respectively).

- Abstract
Fifty circulating strains of Staphylococcus aureus of clinical origin were characterized by their drug susceptibility to 15 antimicrobials through the method of radial diffusion in Mueller Hinton medium. Also, beta-lactam production was determined by acidimetric and chromogenic methods as well as the presence of methicillin-resistant strains. It was confirmed that 32% of strain was susceptible to tested antimicrobials, the most effective of which were imipenem, norfloxacyn, and amikacyn for 98, 96 and 92% susceptibility respectively. Twenty-seven different drug resistance patterns were found in the studied strains. 22% of the total strains was beta-lactam producers whereas 27% of the latter turned out to be methicilline-resistant.
