Resumo: Entre os desafios atuais relacionados à preservação digital do patrimônio está a adoção de processos de normalização e padronização de metadados. Neste artigo são discutidos alguns desafios relacionados à preservação digital e difusão do patrimônio cultural do México no projeto Mexicana, o repositório do patrimônio cultural do México, quatro anos após sua publicação. A partir desta discussão e da comparação do tratamento de dados de um objeto emblemático do México, a "Pedra do Sol", são mostradas as consequências positivas da adoção de processos de normalização específicos, bem como os resultados da estandardização com esquemas de metadados e de propor uma estratégia de interoperação entre repositórios. Além disso, são enunciadas algumas recomendações para a consolidação de um futuro programa de preservação digital de bens de interesse cultural do México, que deve ser consensuado por pesquisadores, administradores, diretores de instituições e outras pessoas no setor cultural mexicano.

Abstract: Among the current challenges related to the digital preservation of heritage is the adoption of metadata normalization and standardization processes. This article discusses some challenges related to the digital preservation and dissemination of Mexico’s cultural heritage in the project Mexicana, el repositorio del patrimonio cultural de México (Mexicana, the repository of Mexico's cultural heritage), four years after its publication. From this discussion and the comparison of the data processing of an emblematic Mexican object, the Piedra de Sol, we show the positive consequences of adopting specific standardization processes and of proposing a strategy of interoperability between repositories, as well as the results of standardization with metadata schemas. Some recommendations are also made to consolidate a future digital preservation program for Mexico’s cultural heritage, which should be agreed upon by researchers, administrators, institution managers, and other agents in the cultural sphere.

Abstract Objective: The objective is to describe the role of leadership in the training of the general surgeon and to point out its relevance. Method: A search of the medical literature was carried out to identify studies that reported on topics related to leadership in the context of medical education and surgery. We used the search engine of Medline/PubMed databases including related terms such as “leadership” AND “medicine” OR “surgery”. Results: Leadership is a valued characteristic in surgery, it implies professionalism, technical competence, motivation, innovation, teamwork, communication skills, decision making, emotional competence, resilience, and effective teaching. Leadership is measurable and can be developed through experience, observation, and education. Conclusions: Priority must be given to actions that improve leader traits. This has been shown to create a work environment where efficient work is performed, and failures are minimized. The current vision of the leader must be expanded to reduce the gender gap between the positions as leader occupy in this moment.

Resumen Objetivo: Describir el papel de liderazgo en la formación del cirujano general y puntualizar su relevancia en nuestro entorno. Método: Se realizó una búsqueda en la literatura médica para identificar estudios que informaran sobre temas relacionados al liderazgo en el contexto de la enseñanza médica y en cirugía. Se utilizó el motor de búsqueda de las bases de datos Medline/PubMed incluyendo términos relacionados como “leadership” AND “medicine” OR “surgery”. Resultados: El liderazgo es una característica valorada en cirugía, que implica profesionalismo, competencia técnica, motivación, innovación, trabajo en equipo, habilidades comunicativas, toma de decisiones, competencia emocional, resiliencia y enseñanza eficaz. Es medible y susceptible de desarrollarse a través de la experiencia, la observación y la educación. Conclusiones: En la formación del cirujano general se deben priorizar las acciones que mejoren los rasgos de líder. Se ha demostrado que esto genera un ambiente de trabajo donde se realiza una labor eficiente y se minimizan las fallas. Se debe expandir la visión actual que se tiene de líder y permitir que se disminuya la brecha de género entre los puestos que hoy se ocupan.

Background: The population of actively working older people is growing rapidly. The relationship between quality of life, levels of physical activity and functionality in this population is not entirely clear. Aim: To determine the association between quality of life, levels of physical activity and functional tests in actively working adults and older people. Material and Methods: Cross sectional assessment of 138 adults aged 40 to 50 years (53% women) and 119 older people aged 60 to 75 years (53% women) who were actively working in two public services. Quality of life was measured with the SF-36 questionnaire and usual physical activity was assessed with the International Physical Activity Questionnaire (IPAQ-short). Handgrip strength, the timed up and go (TUG) and chair stand test (CST) were used as functional tests. Results: Compared to older people, adults had better physical functional tests (P < 0.01). Older people had better scores in the mental health component (MHC) of quality of life (p < 0.05). In adults, the physical health component of quality of life (CSF) had a positive association with physical activity (Spearman Rho (rs)= 0.270; p = 0.01), grip strength (rs = 0.330; p < 0.01) and the TUG (rs = −0.229; p < 0.01). In older patients, CSM and CST were positively correlated (rs = 0.201; P = 0.029). In both groups, a correlation was observed between CSM, grip strength (adults rs = 0.283; p < 0.01; older people rs = 0.211; P = 0.02) and with TUG (adults rs = −0.197; P = 0.021; older people rs = - 0.212; p = 0.02). Conclusions: There is a positive correlation between quality of life and level of physical activity in working adults, which is not observed in older people. Adequate performance in physical functional tests is positively correlated with better quality of life (CSF and CSM) in adults and only with the mental health component in older people.

ABSTRACT The educational processes have undergone many changes due to the Covid-19 pandemic, trying to maintain their continuity through virtual classes, to facilitate this work, the Ministry of Education of Chile establishes the Curricular Prioritization that aims to respond to the various difficulties and problems in the educational environment that emerge due to the paralysis of face-to-face classes caused by the health crisis. The objective of this study was to know if the curricular prioritization in Physical Education and Health is a contribution to the academic training of students, for this, a methodology with a quantitative, non-experimental approach was used, through which information was collected that allowed to know the perception of practicing teachers. The main results indicate that its main contribution is in the conceptual field; however, it presents deficiencies in terms of some relevant aspects for a good development of learning. It is concluded that this organization of objectives has been fairly well received by teachers, although in its application it represents a contribution to the training process.

RESUMO Os processos educacionais sofreram muitas mudanças devido à pandemia de Covid-19, tentando manter sua continuidade por meio de aulas virtuais. Para facilitar este trabalho, o Ministério da Educação do Chile estabelece a Priorização Curricular que visa responder às várias dificuldades e problemas no campo educacional que surgem devido à paralisação das aulas presenciais causadas pela crise da saúde. O objetivo deste estudo foi saber se a priorização curricular em Educação Física e Saúde é uma contribuição para a formação acadêmica dos alunos, para isso, foi utilizada uma metodologia com abordagem quantitativa, não experimental, por meio da qual foram coletadas informações que permitiu conhecer a percepção dos professores atuantes. Os resultados indicam que sua principal contribuição está no campo conceitual, porém, apresenta deficiências em alguns aspectos relevantes para um bom desenvolvimento da aprendizagem. Conclui-se que esta organização de objetivos tem sido moderadamente bem recebida pelos docentes, embora represente um contributo para o processo de formação na sua aplicação.

ABSTRACT: Sjögren’s syndrome (SS) is an immunologically mediated chronic disease of complex etiopathogenesis. Macrophages and Epstein-Barr virus are among the factors related to its development and severity. Macrophages contribute to the local autoimmune process and viral infection promotes the breakdown of self-tolerance. Objectives. Identify the presence of macrophages in the inflammatory infiltrate and Epstein-Barr virus in inflammatory cells, correlating them with the histological features of labial salivary glands. Methodology. In labial salivary glands biopsies of 8 patients and 7 control individuals, anti-CD-68 immunohistochemistry was performed to identify macrophages. The macrophages and inflammatory cells were counted in relation to their distribution in the salivary glands. The presence of the virus was evaluated by in situ hybridization for viral RNA and immunohistochemistry for latent membrane protein type 1. The comparison between both groups was made using the unpaired t-test and Mann-Whitney test. The correlations with histological parameters were established with the Pearson´s correlation coefficient. Results. A greater number of macrophages was observed in the inflammatory infiltrate of SS patients (p=0,001**). Macrophages in control individuals were diffusely distributed in the gland, while, SS in patients, they were mainly located in inflammatory foci. In both groups, no inflammatory or epithelial cells infected by the Epstein-Barr virus were identified. Conclusion. Patients with Sjögren’s syndrome had a greater presence of macrophages and their increase is at the expense of the inflammatory focus.

RESUMEN El síndrome de Sjögren (SS) es una enfermedad crónica mediada inmunológicamente. La presencia de macrófagos y el virus Epstein-Barr (VEB) se ha relacionado con su desarrollo y severidad. Los macrófagos contribuyen al proceso autoinmune local y la infección viral promueve el quiebre de la auto-tolerancia. Objetivos. Identificar la presencia de Macrófagos en el infiltrado inflamatorio y VEB en células inflamatorias, correlacionándolos con las características histológicas de glándulas salivales labiales. Metodología. En biopsias de glándulas salivales labiales (8 pacientes y 7 individuos controles) se realizó inmunohistoquímica antiCD-68 para identificar macrófagos. El conteo de macrófagos y células inflamatorias se efectuó en relación a su distribución en las glándulas salivales. La presencia del virus fue evaluada mediante hibridación in situ e inmunohistoquímica para LMP1. Se utilizó el test t no pareado y de Mann-Whitney para comparar los grupos, y coeficiente de correlación de Pearson para correlacionar con parámetros histológicos. Resultados. Se observó un mayor número de macrófagos en el infiltrado inflamatorio de pacientes (p=0,001**). Los macrófagos se distribuyeron difusamente en las glándulas de controles y en los focos inflamatorios de pacientes. En ambos grupos no se detectó la presencia del virus Epstein-Barr. Conclusión. Los pacientes con síndrome de Sjögren presentaron mayor presencia de macrófagos y su incremento es a expensas del foco inflamatorio.

Abstract This study consisted of determining the effect of Bacillus strains inoculated alone or in combination with phytopathogenic fungi on the production of human health-related compounds and volatile organic compounds (VOCs) in tomato fruits. Seedlings were cultivated under greenhouse conditions and inoculated with B. amyloliquefaciens, B. methylotrophicus and B. subtilis alone or in combination with Alternaria solani, Fusarium oxysporum and Phytophthora infestans. Fully ripe fruits were harvested and evaluated for carotenoid, phenol and VOCs contents. Lycopene was the most abundant carotenoid (46.4-167.62 µg/g), followed by β-carotene and lutein. Fruits from plants inoculated with Bacillus had the highest carotenoid content. In contrast, phytopathogens decreased the carotenoid contents, especially the lycopene content. The content of total phenols ranged from 0.42 to 0.90 mg GAE/g. The content of these compounds increased 1.5-fold in fruits from plants inoculated with Bacillus strains, especially those treated with B. methylotrophicus, but the greatest increase (1.9-fold) was observed in plants inoculated with phytopathogens. Both Bacillus strains and pathogens increased the antioxidant capacity, with a 2.8-fold increase compared to the control. Thirty-two VOCs were identified in the tested tomatoes. The Bacillus strains caused an increase in the concentration of VOCs, which could be associated with an increase in fruit quality.

SUMMARY: Orthognathic surgery is performed in subjects with some type of skeletal alteration. Maxillomandibular movements have an impact on the airway (AW) and this aspect must be included into surgical planning. The aim of this research is to determine the changes in the AW after orthognathic surgery. A pilot study was conducted including 51 subjects with class II and class III facial deformity; they were included using the ANB angle and the type of dental occlusion. Cone beam computed tomography were performed showing the maximum volume in the airway and the minimum and maximum areas; in addition, the position of the hyoid bone and the angle of the mandibular plane were included to relate it to the morphology of the AW; to define statistical significance, a value of p<0.05 was established, including the student's t-test and the t-test. The results showed that class II subjects significantly increased the volume and maximum and minimum areas of the AW; skeletal class III subjects did not presented significant differences between the pre- and post-surgical stage; the hyoid bone was in an anterior position in both class II and class III cases. It is possible to conclude that AW improves substantially in subjects with facial class II and remains unchanged in subjects with facial class III.

RESUMEN: La cirugía ortognática se realiza en sujetos con algún tipo de alteración esqueletal. Los movimientos maxilo mandibulares tienen impacto en la vía aérea (VA) y este aspecto se debe incorporar en la planificación quirúrgica. El objetivo de esta investigación fue determinar los cambios generados en la VA después de realizada la cirugía ortognática. Se realizó un estudio piloto incluyendo 51 sujetos con deformidad facial de clase II y clase III; se incluyeron en base al estudio del ángulo ANB y el tipo de oclusión dentaria. Se realizaron estudios con tomografía de haz cónico identificando el volumen máximo en la vía área y las áreas mínimas y máximas; además se incluyó la posición del hueso hioide y la inclinación del plano mandibular para relacionar con la morfología de la VA; para definir significancia estadística se estableció un valor de p<0,05 incluyendo las pruebas T de student y T test. Los resultados indicaron que los sujetos clase II aumentaron significativamente el volumen y áreas máximas y mínimas de la VA; los sujetos de clase III esqueletal no presentaron diferencias significativas entre la etapa pre y post quirúrgica; el hueso hioides se presentó significativamente más anterior en ambos en casos de clase II y clase III. Es posible concluir que la VA mejora sustancialmente en sujetos con clase esqueletal facial tipo II y que se mantiene sin cambios en sujetos con clase facial tipo III.

ABSTRACT Introduction: In Cuba, the training of teaching personnel has been a concern from the very triumph of the Cuban Revolution to the present, as has been the training and improvement of those who direct these teachers. The study carried out on the formation of educational leadership in the school principals of the Morón municipality, Cuba, shows that they have shortcomings in their preparation to perform efficiently. Objectives: Characterize the educational leadership competence of school principals. Develop a strategy to form educational leadership competence in school principals. Methods: A methodology is used for the construction of the theoretical construct of educational leadership competence of school principals: Bibliographic Review, Virtual Debate Forum, Discussion Groups, Diagnosis of Practice and Ibero American Experts’ Judgment (35); this last method made it possible to create of the Ibero American Network of Leadership and Educational Practices (RILPE). Results and Discussion: Contributions are made to the training of school principals (2015-2020). In a general way, the management style is studied, as well as the influence they exert on the membership of educational institutions and the training processes of directive leadership in Ibero America. A leadership training strategy was developed taking into account the improvement, research and methodological work as access routes to the training of the cadres. The scientific result was validated through expert judgment. Its implementation was evaluated through the index of group satisfaction.

ABSTRACT: The objective of this research was to determine the preferred movements in the maxilla and mandible to obtain normality in facial morphology using superimposition techniques in 3D analysis. A descriptive study was carried out to evaluate bimaxillary bone displacement and hyoid bone in subjects facial class II and facial class III undergoing orthognathic surgery. were used as fixed points for superimposition: Nasion (N) - Silla (S) - Porion (Po) and the zygomatic-maxillary suture (Z). These points were superimposed in pre-surgical and post- surgical CBCT and was evaluated to displacement of the anterior nasal spine, Point A, Point B, Chin and the hyoid bone. For the evaluation and comparison of continuous variables before and after orthognathic surgery, was used the Student's t test. For the correlation between the variables, the Spearman test is used, considering a p value <0.05 as a significant difference. 44 subjects between 18 and 40 years old of both sexes were included in this research. A 90% of subjects a was performed a maxillay sagittal movement. The sagittal movement of mandibular advancement was performed in 100% with facial class type II, while 100 % of the subjects with with facial class type III had a mandibular recession. The hyoid bone advanced in 26 of the 27 subjects with facial class type II. It is possible to conclude that there is a tendency for maxillary advancement, independent of facial deformity.

RESUMEN: El objetivo de esta investigación fue determinar los movimientos preferidos en maxila y mandíbula para obtener normalidad en morfología facial utilizando técnicas de superimposición en análisis 3D. Se realizó un estudio descriptivo para evaluar el desplazamiento óseo bimaxilar y del hueso hioides en sujetos clase facial tipo II y clase facial tipo III sometidos a cirugía ortognática. Para la superimposición se utilizó como puntos fijos Nasion - Silla - Porion y la sutura cigomática-maxilar. Estos puntos se superpusieron en CBCT pre quirúrgico y postquirúrgico y se evaluó el desplazamiento de la espina nasal anterior, Punto A, Punto B, mentón y del hueso hioides. Para la evaluación y comparación de las variables continuas antes y después de la cirugía ortognática se utilizó la prueba T de Student. Para la correlación entre las variables, se utilizó el Test de Spearman considerando un valor p<0,05 como diferencia significativa. 44 sujetos de entre 18 y 40 años de ambos sexos, fueron incluidos en esta investigación. En el 90 % de los sujetos se realizó un movimiento sagital de avance de la maxila. El movimiento sagital de avance mandibular se realizó en el 100 % de los sujetos con clase facial tipo II, mientras que el 100 % de los sujetos con clase facial tipo III se realizó se le retroceso mandibular. El hueso hioides presentó un avance en 26 de los 27 sujetos con clase facial tipo III. Es posible concluir que existe una tendencia al avance maxilar independiente de la deformidad facial.

Resumen Este INFORME ACADÉMICO describe el proceso de implementación del estándar Object ID usando Tainacan, un software gratuito de código abierto, en cuatro instituciones museológicas de distintos países, Brasil y México, como un estudio contrastivo de caso. Consideramos la hipótesis de que ambos países comparten similitudes relacionadas con los contextos culturales y los objetos patrimoniales. Por ende, esperábamos resultados similares, como los beneficios observados de usar un programa de documentación y un esquema de metadatos. En este estudio de caso presentamos los resultados preliminares de una investigación en curso, y como se verá, aún queda mucho por hacer. Para el futuro estamos considerando ampliar el experimento a otros estándares como el Lightweight Information Describing Objects (LIDO).

Abstract This academic report describes the implementation process of the Object ID standard using Tainacan, a free open-source software which included four museological institutions from different countries -Brazil and Mexico- as a comparative case study. We considered the hypothesis that the two countries share similarities related to cultural contexts and heritage objects. Therefore, we expected similar results, such as the observed benefits of using a documentation software and a metadata schema. In this case study, we present the results of this investigation, but as will be seen, much remains to be done. As a prospect for the future, we are considering to expand the experiment to other standards, such as the Lightweight Information Describing Objects (LIDO) standard.

Abstract Beans have been an essential food for mexicans since ancient times. In the past, beans were cooked in clay pots with spices (epazote or bay leaf) added. Today, pressure cookers have replaced clay cookers, and herbs are almost a lost tradition. To understand traditional cooking methods, the present work evaluated the effect of the addition of spices (laurel or epazote) and the cooking method (clay pot or pressure cooker), on antinutritional characteristics and bacterial inhibition. The results show that the traditional techniques, clay pot, spices addition (epazote and bay leaf), and soaking, considerably decrease the concentration of α-oligosaccharides. On the other hand, when cooking in a pressure cooker with previous soaking, the concentration of phytic acid decreases to a greater extent, and reduces the activity of trypsin inhibitor compounds. On the other hand, the use of spices inhibits microbial growth. A combination of traditional Mexican cuisine (soaking and herbs usage) and modern cuisine (pressure cooker) decreases antinutritional compounds and preserves the beans’ microbial quality. These results show the importance of studying and maintaining traditional Mexican cuisine.

Resumen El frijol ha sido un alimento importante para los mexicanos desde tiempos ancestrales. En el pasado, los frijoles eran cocinados en ollas de barro agregando especias (epazote o laurel). En la actualidad, las ollas de presión han remplazado a las de barro y el uso de especias es casi una tradición perdida. Para comprender los métodos tradicionales de cocción, el presente trabajo evaluó el efecto de la adición de especias (laurel o epazote) y del método de cocción (olla de barro o de presión), sobre las características antinutricionales y la inhibición bacteriana. Los resultados muestran que los métodos tradicionales, olla de barro, adición de epazote y laurel, así como el remojo, disminuyen considerablemente la concentración de α-oligosacáridos. Mientras que la cocción en olla de presión con previo remojo, disminuye en mayor proporción la concentración de ácido fítico y reduce la actividad de los compuestos inhibidores de tripsina. Por otro lado, el uso de especias inhibe el crecimiento microbiano. Una combinación de cocina tradicional mexicana (remojo y uso de especias) y cocina moderna (olla a presión) disminuye los compuestos antinutricionales y conserva la calidad microbiana de los frijoles. Estos resultados muestran la importancia de estudiar y preservar la cocina tradicional mexicana.

Abstract INTRODUCTION: Antimicrobial resistance has worsened since the onset of COVID-19. METHODS: This study involved patients admitted to the adult intensive care unit (ICU) of a tertiary hospital. Pre- and post-COVID-19 data were analyzed. The healthcare-related infections (HCRIs) reported between January 2018 and January 2020 and during the pandemic between February and July 2020 were compared. RESULTS: Antimicrobial resistance increased during the pandemic, especially for Klebsiella pneumoniae isolates, with a rate increase from 5% to 50% for Polymyxin B. CONCLUSIONS: The susceptibilities of the main pathogens associated with HCRIs in the ICU changed and should be considered in managing severe COVID-19.

Resumo Objetivos: Avaliar a presença de síndrome das pernas inquietas, movimento periódico das pernas e distúrbios do sono em adolescentes do sexo feminino com dor musculoesquelética idiopática por meio da escala do sono e da polissonografia e comparar esses dados em adolescentes sem histórico de dor. Método: Foram recrutados 26 adolescentes diagnosticados com dor musculoesquelética idiopática acompanhados em um ambulatório de dor e 25 controles saudáveis pareados por idade e escolaridade. Avaliamos os critérios da síndrome das pernas inquietas de acordo com o Grupo Internacional de Estudos de Síndrome das Pernas Inquietas, a Escala de Distúrbios do Sono em Crianças, a polissonografia noturna e os sintomas de ansiedade. Resultados: A idade média dos adolescentes com dor musculoesquelética idiopática foi 13,9 ± 1,6 anos e dos controles foi 14,4 ± 1,4 anos. Um adolescente no grupo de controle (4%) e nove pacientes com dor musculoesquelética idiopática (34,6%) atenderam aos critérios da síndrome das pernas inquietas (p = 0,011). Não observamos diferenças significativas nos escores da Escala de Distúrbios do Sono em Crianças entre os grupos em todos os componentes: distúrbios do início e da manutenção do sono (p = 0,290), distúrbios respiratórios do sono (p = 0,576), distúrbios do despertar (p = 0,162), distúrbios da transição sono-vigília (p = 0,258), sonolência diurna excessiva (p = 0,594) e hiperidrose do sono (p = 0,797). Os parâmetros neurofisiológicos, respiratórios e o movimento periódico das pernas foram semelhantes nos dois grupos. Ansiedade não foi associada à síndrome das pernas inquietas (p = 0,11). Três pacientes com dor musculoesquelética idiopática (11,5%) apresentaram síndrome das pernas inquietas e movimento periódico das pernas simultaneamente, situação ausente no grupo de controle. Conclusão: As adolescentes do sexo feminino com dor musculoesquelética idiopática apresentaram critérios para síndrome das pernas inquietas com mais frequência do que as adolescentes saudáveis. Contudo, não observamos mudanças relevantes nas variáveis do sono objetivas e subjetivas.

Abstract Objectives: To assess the presence of restless legs syndrome, periodic leg movement, and sleep disorders in female adolescents with idiopathic musculoskeletal pain through a sleep scale and polysomnography, and to compare these data in adolescents without pain history. Method: Twenty-six adolescents diagnosed with idiopathic musculoskeletal pain followed in a pain outpatient clinic and 25 healthy controls matched by age and education were recruited. The restless legs syndrome criteria were evaluated according to the International Restless Legs Syndrome Study Group, the Sleep Disturbance Scale for Children was completed, nocturnal polysomnography was performed, and anxiety symptoms were recorded. Results: The mean age of idiopathic musculoskeletal pain adolescents was 13.9 ± 1.6 years; in controls, it was 14.4 ± 1.4 years. One adolescent in the control group (4 %) and nine patients with idiopathic musculoskeletal pain (34.6 %) fulfilled the restless legs syndrome criteria (p = 0.011). The authors did not observe significant differences in Sleep Disturbance Scale for Children scores between the groups in all components: disorders of initiating and maintaining sleep (p = 0.290), sleep breathing disorders (p = 0.576), disorders of arousal (p = 0.162), sleep-wake transition disorders (p = 0.258), disorder of excessive daytime somnolence (p = 0.594), and sleep hyperhidrosis (p = 0.797). The neurophysiological, respiratory, and periodic leg movement parameters were similar in both groups. Having anxiety was not associated with restless legs syndrome (p = 0.11). Three patients with idiopathic musculoskeletal pain (11.5 %) presented restless legs syndrome and periodic leg movement simultaneously, which was absent in the control group. Conclusion: Female adolescents with idiopathic musculoskeletal pain present criteria for RLS more frequently than healthy adolescents. However, this study did not observe relevant changes in objective and subject sleep variables.

Background: Simulation models provide controlled environments for the practice and tutor feedback. Faced with a first experience, our group implemented a simplified and reproducible model for the training of basic surgical skills. Aim: Communicate the results of a training workshop based on simulation for the basic surgical skills training in medical students. Materials and Method: Quasi-experimental study, before and after, 124 fourth year medical students were trained with “EPROBA” methodology, with prior informed consent. Through the instrument “The Objective Structured Assessment of Technical Skills” (OSATS) the technique of suture before and after the intervention was evaluated. The perception of the students was evaluated through a validated survey. For statistical analysis SPSS24® was used and the Mann Whitney test was used for nonparametric variables, it was considered significant p < 0.05. Results: The group shows a significant average progress in its procedural performance. In the OSATS Checklist they show a progress from 4.1 points to 8.9 after the intervention (p < 0.001). In the OSATS Global Scale they show a baseline score of 13.0 points, rising to 28.0 points (p < 0.001). The intervention was well perceived, obtaining a total average score of 65.4 points of 68 maximums. Conclusión: In our experience, a simplified model proved to be effective for training in simple procedural skills such as sutures. Multiple instances of practice must be granted by the Faculties of Medicine for the retention and improvement of these skills.

Resumen Introducción: Los modelos de simulación otorgan entornos controlados para la práctica y la retroalimentación por parte de un tutor. Frente a una primera experiencia, nuestro grupo implementó un modelo simplificado y reproducible para el entrenamiento de habilidades quirúrgicas básicas. Objetivo: Comunicar los resultados de un taller de entrenamiento basado en simulación para la adquisición de habilidades quirúrgicas básicas en estudiantes de Medicina. Materiales y Método: Estudio cuasiexperimental, antes y después, 124 estudiantes de medicina de cuarto año fueron entrenados con la metodología EPROBA (Entrenamiento Procedimental Básico), previo consentimiento informado. Mediante el instrumento “The Objective StructuredAssessment Of Technical Skills” (OSATS) se evaluó la técnica de sutura previo y posterior a la intervención. Se evaluó la percepción de los estudiantes mediante una encuesta validada. Para el análisis estadístico se utilizó SPSS24® y se usó la prueba Mann Whitney para variables no paramétricas considerando significativo p < 0,05. Resultados: El grupo muestra un progreso promedio significativo en su desempeño procedimental. En la Lista de Comprobación OSATS muestra un progreso desde 4,1 puntos a 8,9 (p < 0,001). En la Escala Global OSATS muestra un puntaje basal de 13,0 puntos, aumentando a 28,0 puntos (p < 0,001). La intervención fue bien percibida, obteniendo un puntaje total promedio de 65,4 puntos de 68 máximos. Conclusión: En nuestra experiencia, un modelo simplificado demostró ser eficaz para el entrenamiento en habilidades procedimentales simples como suturas. Múltiples instancias de práctica deben ser otorgadas por las Facultades de Medicina para la retención y mejora de estas habilidades.
