Introduction: it is known that during the period of the COVID-19 pandemic, schools and teachers needed to adapt with alternatives to continue classes. Purpose: Investigate pedagogical learning strategies and resources adopted by teachers from public and/or private schools in the interior of a Brazilian state during the period of suspension of face-to-face classes, due to the Covid-19 Pandemic and its effects on students with and without learning difficulties. Method: This research included the application of an online questionnaire through Google Forms to 37 active teachers from the 1st to the 5th year of the public and/or private network at Brasilian state who have worked remotely during the Pandemic during the suspension period of in-person classes. This material contained multiple choice questions and essays, referring to the way of working during this period, strategies and resources adopted. Results: The results showed that the most used strategies by teachers were the use of printed materials. Teachers reported the difficulties and challenges in adopting remote teaching, referring to the social inequality of students, the limited commitment of families in the learning process and the difficulty of teachers to adapt to this form of teaching. Conclusion: Among 37 teachers who joined the study, it was possible to verify how the process of adaptation to remote teaching took place. There is a need to explore the joint work with Speech Therapy, aiming to minimize the difficulties presented by students. Such clarifications would help in the teaching and learning process of students who could later become future patients in the Speech Therapy sector. (AU)

ABSTRACT

Resumen Introducción : El Trastorno del Espectro Autista (TEA) es un trastorno del neurodesarrollo, y sus procedimien tos tradicionales de evaluación encuentran ciertas li mitaciones. El actual campo de investigación sobre TEA está explorando y respaldando métodos innovadores para evaluar el trastorno tempranamente, basándose en la detección automática de biomarcadores. Sin embargo, muchos de estos procedimientos carecen de validez ecológica en sus mediciones. En este contexto, la reali dad virtual (RV) presenta un prometedor potencial para registrar objetivamente bioseñales mientras los usuarios experimentan situaciones ecológicas. Métodos : Este estudio describe un novedoso y lúdi co procedimiento de RV para la evaluación temprana del TEA, basado en la grabación multimodal de bio señales. Durante una experiencia de RV con 12 esce nas virtuales, se midieron la mirada, las habilidades motoras, la actividad electrodermal y el rendimiento conductual en 39 niños con TEA y 42 compañeros de control. Se desarrollaron modelos de aprendizaje automático para identificar biomarcadores digitales y clasificar el autismo. Resultados : Las bioseñales reportaron un rendimien to variado en la detección del TEA, mientras que el modelo resultante de la combinación de los modelos de las bioseñales demostró la capacidad de identificar el TEA con una precisión del 83% (DE = 3%) y un AUC de 0.91 (DE = 0.04). Discusión : Esta herramienta de detección pue de respaldar el diagnóstico del TEA al reforzar los resultados de los procedimientos tradicionales de evaluación.


Abstract Introduction : Autism Spectrum Disorder (ASD) is a neurodevelopmental condition which traditional as sessment procedures encounter certain limitations. The current ASD research field is exploring and endorsing innovative methods to assess the disorder early on, based on the automatic detection of biomarkers. How ever, many of these procedures lack ecological validity in their measurements. In this context, virtual reality (VR) shows promise for objectively recording biosignals while users experience ecological situations. Methods : This study outlines a novel and playful VR procedure for the early assessment of ASD, relying on multimodal biosignal recording. During a VR experience featuring 12 virtual scenes, eye gaze, motor skills, elec trodermal activity and behavioural performance were measured in 39 children with ASD and 42 control peers. Machine learning models were developed to identify digital biomarkers and classify autism. Results : Biosignals reported varied performance in detecting ASD, while the combined model resulting from the combination of specific-biosignal models demon strated the ability to identify ASD with an accuracy of 83% (SD = 3%) and an AUC of 0.91 (SD = 0.04). Discussion : This screening tool may support ASD diagnosis by reinforcing the outcomes of traditional assessment procedures.

ABSTRACT

En la asignatura de anatomía aún existen estudiantes que no se encuentran motivados con su propio proceso de aprendizaje. El rol del docente es un factor extrínseco clave que contribuye a dicha vinculación afectiva. El Diseño Universal para el Aprendizaje (DUA) es un modelo educativo que propone una serie de pautas de aplicación docente para poder activar en los alumnos sus redes neuronales afectivas, asociadas con la formación de estudiantes decididos y motivados. El objetivo de este estudio es crear una propuesta de intervención, basada en el uso selectivo de las pautas de compromiso afectivo del DUA, para mejorar la práctica docente y la motivación de los estudiantes en anatomía. Es una investigación acción que utiliza el modelo de Whitehead, implicando el cruce conceptual y metodológico entre las pautas de compromiso afectivo del DUA y las fases y factores que determinan la motivación. Corresponde a la programación de seis sesiones de laboratorio de anatomía, los instrumentos para la recopilación de la información y las técnicas de análisis de la misma. La propuesta de intervención presenta un valor teórico ya que fue diseñada a partir de un análisis exhaustivo del DUA y de las publicaciones existentes sobre la motivación, y un valor práctico que se sustenta en su aplicabilidad directa y recursiva en los laboratorios de anatomía y en la incorporación del DUA en el currículum de una asignatura de educación superior. La motivación es el motor de la educación, ya que impulsa y mantiene el quehacer académico tanto a nivel estudiantil como docente. El DUA permite que los docentes aborden la desmotivación de los estudiantes de una forma accesible, precisa y confiable, lo que llevó a considerarlo como uno de los pilares de la propuesta de intervención.


SUMMARY: In anatomy courses there are still students who are not motivated by their own learning process. The teacher´s role is a key extrinsic factor that contributes to this bonding process. Universal Design for Learning (UDL) is an educational model that proposes a series of teaching application guidelines to activate students' affective neural networks, associated with the formation of motivated students. The objective of this study is to create an intervention proposal, based on the selective use of the UDL affective commitment guidelines, to improve teaching practice and student motivation in anatomy. It is an action research that uses Whitehead's model, involving the conceptual and methodological intersection between the UDL's affective commitment guidelines and the phases and factors that determine motivation. It corresponds to the programming of six anatomy laboratory sessions, the instruments for collecting information and the techniques for analyzing it. The intervention proposal has a theoretical value since it was designed based on an exhaustive analysis of the UDL and existing publications on motivation, and a practical value that is based on its direct and recursive applicability in anatomy laboratories and in the incorporation of the UDL in the curriculum of a higher education subject. Motivation is the driving force of education, since it drives and maintains academic work at both the student and teacher level. The UDL allows teachers to address student lack of motivation in an accessible, precise and reliable way, considering this one of the pillars of the intervention proposal.

ABSTRACT

Aprendizajes en anatomía humana tradicionalmente han sido evaluados a través del reconocimiento de estructuras anatómicas. A pesar de su popularidad, pueden tener un componente subjetivo y memorístico. El Examen Práctico Objetivo Estructurado (EPOE) se ha presentado como una manera más global de evaluación. El objetivo de este estudio fue evidenciar el efecto en el rendimiento académico tras la implementación del EPOE en pasos prácticos. En el estudio 2312 estudiantes fueron divididos: Metodología Tradicional (n=1155) y Metodología EPOE (n=1157). A su vez, los estudiantes fueron identificados según carrera: Enfermería (n=1182); Fonoaudiología (n=185); Kinesiología (n=514) y Terapia Ocupacional (n=431). Se mantuvieron las condiciones de la asignatura en ambos grupos con tres evaluaciones prácticas. Se analizaron las calificaciones obtenidas. Evaluaciones 1 y 2 no presentaron diferencias entre grupos. Evaluación 3, que evaluó sistema nervioso, mostró disminución significativa de 0,5 puntos en el grupo EPOE. El factor tipo de metodología resultó ser significativo en evaluación 3 (p < 0,001; h2p = 0,029) y promedio de las 3 evaluaciones (p < 0,029; h2p = 0,002). El factor carrera resultó ser significativo para las tres evaluaciones. La interacción de ambos factores no mostró significancia estadística. El análisis post hoc mostró diferencias significativas entre estudiantes de Enfermería con las demás carreras, ya que obtuvieron mejores calificaciones en todas las evaluaciones (p < 0,05). Metodología EPOE no produjo drásticos cambios en el rendimiento académico de los estudiantes y tiene un amplio potencial de desarrollo por su naturaleza de evaluación integral no invasiva ni traumática. Se debe considerar la naturaleza de los contenidos en el diseño de la metodología de enseñanza-aprendizaje y en la metodología de evaluación, alineando a nivel microcurricular estos aspectos fundamentales de la formación de nuevos profesionales de la salud.


SUMMARY: Learning in human anatomy has traditionally been assessed by recognizing anatomical structures. Despite their popularity, they can have a subjective component. The Objective Structured Practical Examination (EPOE) has been presented as a more global way of assessment. The aim of this study was to demonstrate the effect on academic performance after the implementation of the EPOE in practical activities. In this study 2312 students were divided into Traditional Methodology (n=1155) and EPOE Methodology (n=1157). In turn, students were identified according to career: Nursing (n=1182), Speech Therapy (n=185), Physical Therapy (n=514), and Occupational Therapy (n=431). Subject conditions were maintained in both groups with three practical evaluations. The grades obtained were analyzed. Assessments 1 and 2 showed no differences between groups. Evaluation 3, which evaluated the nervous system, showed a significant decrease of 0.5 points in the EPOE group. The type of methodology factor was significant in evaluation 3 (p < 0.001; ?2p = 0.029) and the average of 3 evaluations (p < 0.029; ?2p = 0.002). The career factor was significant for all three evaluations. The interaction of both factors did not show statistical significance. The post hoc analysis showed significant differences between nursing students and the other careers since they obtained better scores in all evaluations (p < 0.05). EPOE methodology did not produce drastic changes in students' academic performance and had a broad potential for development due to its non-invasive and non-traumatic comprehensive assessment nature. The nature of the contents should be considered in the design of the teaching-learning methodology and the evaluation methodology, aligning at the micro-curricular level with these fundamental aspects of training new health professionals.

ABSTRACT

RESUMEN Introducción: El número creciente de estudios ecocardiográficos y la necesidad de cumplir rigurosamente con las recomendaciones de guías internacionales de cuantificación, ha llevado a que los cardiólogos deban realizar tareas sumamente extensas y repetitivas, como parte de la interpretación y análisis de cantidades de información cada vez más abrumadoras. Novedosas técnicas de machine learning (ML), diseñadas para reconocer imágenes y realizar mediciones en las vistas adecuadas, están siendo cada vez más utilizadas para responder a esta necesidad evidente de automatización de procesos. Objetivos: Nuestro objetivo fue evaluar un modelo alternativo de interpretación y análisis de estudios ecocardiográficos, basado fundamentalmente en la utilización de software de ML, capaz de identificar y clasificar vistas y realizar mediciones estandarizadas de forma automática. Material y métodos: Se utilizaron imágenes obtenidas en 2000 sujetos normales, libres de enfermedad, de los cuales 1800 fueron utilizados para desarrollar los algoritmos de ML y 200 para su validación posterior. Primero, una red neuronal convolucional fue desarrollada para reconocer 18 vistas ecocardiográficas estándar y clasificarlas de acuerdo con 8 grupos (stacks) temáticos. Los resultados de la identificación automática fueron comparados con la clasificación realizada por expertos. Luego, algoritmos de ML fueron desarrollados para medir automáticamente 16 parámetros de eco Doppler de evaluación clínica habitual, los cuales fueron comparados con las mediciones realizadas por un lector experto. Finalmente, comparamos el tiempo necesario para completar el análisis de un estudio ecocardiográfico con la utilización de métodos manuales convencionales, con el tiempo necesario con el empleo del modelo que incorpora ML en la clasificación de imágenes y mediciones ecocardiográficas iniciales. La variabilidad inter e intraobservador también fue analizada. Resultados: La clasificación automática de vistas fue posible en menos de 1 segundo por estudio, con una precisión de 90 % en imágenes 2D y de 94 % en imágenes Doppler. La agrupación de imágenes en stacks tuvo una precisión de 91 %, y fue posible completar dichos grupos con las imágenes necesarias en 99% de los casos. La concordancia con expertos fue excelente, con diferencias similares a las observadas entre dos lectores humanos. La incorporación de ML en la clasificación y medición de imágenes ecocardiográficas redujo un 41 % el tiempo de análisis y demostró menor variabilidad que la metodología de interpretación convencional. Conclusión: La incorporación de técnicas de ML puede mejorar significativamente la reproducibilidad y eficiencia de las interpretaciones y mediciones ecocardiográficas. La implementación de este tipo de tecnologías en la práctica clínica podría resultar en reducción de costos y aumento en la satisfacción del personal médico.


ABSTRACT Background: The growing number of echocardiographic tests and the need for strict adherence to international quantification guidelines have forced cardiologists to perform highly extended and repetitive tasks when interpreting and analyzing increasingly overwhelming amounts of data. Novel machine learning (ML) techniques, designed to identify images and perform measurements at relevant visits, are becoming more common to meet this obvious need for process automation. Objectives: Our objective was to evaluate an alternative model for the interpretation and analysis of echocardiographic tests mostly based on the use of ML software in order to identify and classify views and perform standardized measurements automatically. Methods: Images came from 2000 healthy subjects, 1800 of whom were used to develop ML algorithms and 200 for subsequent validation. First, a convolutional neural network was developed in order to identify 18 standard echocardiographic views and classify them based on 8 thematic groups (stacks). The results of automatic identification were compared to classification by experts. Later, ML algorithms were developed to automatically measure 16 Doppler scan parameters for regular clinical evaluation, which were compared to measurements by an expert reader. Finally, we compared the time required to complete the analysis of an echocardiographic test using conventional manual methods with the time needed when using the ML model to classify images and perform initial echocardiographic measurements. Inter- and intra-observer variability was also analyzed. Results: Automatic view classification was possible in less than 1 second per test, with a 90% accuracy for 2D images and a 94% accuracy for Doppler scan images. Stacking images had a 91% accuracy, and it was possible to complete the groups with any necessary images in 99% of cases. Expert agreement was outstanding, with discrepancies similar to those found between two human readers. Applying ML to echocardiographic imaging classification and measurement reduced time of analysis by 41% and showed lower variability than conventional reading methods. Conclusion: Application of ML techniques may significantly improve reproducibility and efficiency of echocardiographic interpretations and measurements. Using this type of technologies in clinical practice may lead to reduced costs and increased medical staff satisfaction.

ABSTRACT

RESUMEN La inteligencia artificial (IA) está basada en programas computacionales que pueden imitar el pensamiento humano y automatizar algunos procesos. En el ámbito médico se está estudiando hace más de 50 años, pero en los últimos años el crecimiento ha sido exponencial. El campo de las imágenes cardiovasculares es particularmente atractivo para aplicarla, dado que, guiadas por IA, personas no expertas pueden adquirir imágenes completas, automatizar procesos y mediciones, orientar diagnósticos, detectar hallazgos no visibles al ojo humano, realizar diagnósticos oportunistas de afecciones no buscadas en el estudio índice pero evaluables a través de las imágenes disponibles, o identificar patrones de asociación dentro de una gran cantidad de datos como fuente de generación de hipótesis. En el campo de la prevención cardiovascular, la IA se ha aplicado en diferentes escenarios con fines diagnósticos, pronósticos y terapéuticos en el manejo de algunos factores de riesgo cardiovascular, como las dislipidemias o la hipertensión arterial. Si bien existen limitaciones con el uso de la IA tales como el costo, la accesibilidad y la compatibilidad de los programas, la validez externa de los resultados en determinadas poblaciones, o algunos aspectos éticos-legales (privacidad de los datos), esta tecnología está en crecimiento vertiginoso y posiblemente revolucione la práctica médica actual.


ABSTRACT Artificial intelligence (AI) is based on computer programs that imitate human thinking and automate certain processes. Artificial intelligence has been studied in the medical field for over 50 years, but in recent years, its growth has been exponential. The field of cardiovascular imaging is particularly attractive since AI can guide non-experts in image acquisition, automate processes and measurements, guide diagnoses, detect findings not visible to the human eye, make opportunistic diagnoses of unexpected conditions in the index test, or identify patterns of association within a large amount of data as a source of hypothesis generation. In the field of cardiovascular prevention, AI has been used for diagnostic, prognostic, and therapeutic purposes in managing cardiovascular risk factors such as dyslipidemia and hypertension. While there are limitations to the use of AI, such as cost, accessibility, compatibility of programs, external validity of results in certain populations, and ethical-legal aspects such as data privacy, this technology is rapidly growing and is likely to revolutionize current medical practice.

ABSTRACT

ObjectiveTo investigate the application of endoscopy in obtaining the great saphenous vein (GSV) during coronary artery bypass grafting (CABG) and explore the learning curve, with a particular focus on common challenges encountered during the learning process and their impact on early clinical outcomes. MethodsA retrospective analysis was conducted on clinical data from 83 patients who underwent off-pump CABG with endoscopic GSV harvesting at the First Affiliated Hospital of Zhengzhou University from July 2013 to April 2014. Patients were categorized into four groups based on the chronological order of their hospitalization: Group A (novice group, n=20), Group B (proficient group, n=20), Group C (progressive group, n=20), and Group D (mature group, n=23). Differences in perioperative and midterm follow-up outcomes among the groups were analyzed to determine the learning curve period. ResultsThe study population had a mean age of (60.22±8.06) years and a mean body weight of (69.77±11.66) kg. Comorbidities included hypertension (24 cases), diabetes (26 cases), and subacute cerebral infarction (14 cases). The novice group exhibited significantly shorter GSV length-to-harvest time ratio relative to the other three groups (P<0.001) and a significantly higher incidence of main vein damage (P=0.006). However, there was no statistically significant difference in graft patency at the 1-year follow-up. ConclusionThorough and reliable technical training in endoscopic GSV harvesting is essential to minimize vascular injury caused by novice operators. Approximately 20 cases of hands-on experience and a careful self-analysis of procedural challenges are likely required to achieve proficiency in GSV harvesting.

ABSTRACT

Aim To investigate the effect of safflower yellow (SY) on learning and memory ability of APP/ PS1 mice at different disease stages, and to explore the mechanism of SY anti- Alzheimer's disease by using 3-,6- and 9-month-old APP/PS 1 transgenic mice as experimental animal models. Methods Behavioral experiments were conducted to observe the effects of SY on learning and memory of APP/PS1 mice of different months. ELISA was used to detect the effect of SY on the expression of inflammatory factors in cortex of mice of different months. Western blot was used to detect the microglia activation marker protein, and its mechanism of action was further analyzed. Results SY could enhance the learning and memory ability of mice aged 3, 6 and 9 months, reduce the content of IL-6 and increase the content of TGF-β1 in brain tissue, up-regulate the expression levels of arginase-1 (arg-1) and triggering receptor expressed on myeloid cells 2 (tREM2) in brain tissue of mice of different months, and down-regulate the expression levels of inducible nitric oxide synthase (iNOS), Toll-like receptors 4 (tlr4) and nuclear factor-kappa B (nf-KB). Conclusions Compared with 3- and 9-month-old mice, SY is the most effective in improving learning memory in 6-month-old APP/PS1 mice. SY inhibits TLR4/NF-KB pathway activation by inducing TREM2 expression in brain tissue of APP/PS 1 transgenic mice, promotes microglia phenotype shift to anti-inflammatory phenotype, reduces chronic neuroinflammatory response, and improves learning memory in APP/PS1 mice at all months of age.

ABSTRACT

Objective@#To explore the mediating effect of rumination between life events and learning value doubt among junior high school students, so as to provide reference for the psychological health education of junior high school students.@*Methods@#From March to July 2023, a total of 930 junior high school students from Guangdong, Jiangsu and Hebei were selected by a combination of convenient sampling methods. Participants completed the Scales of Value of Learning (SVL), Ruminative Response scale (RRS) and Adolescent Self rating Life Events Checklist (ASLEC). The t test and ANOVA were used for inter group comparisons and Pearson correlation analysis was used for correlation analysis and bootstrap method was used for mediating effect test.@*Results@#The life events of junior middle school students were positively correlated with learning value doubt ( r =0.18), rumination ( r = 0.65 ) and its three dimensions (brooding, reflective pondering, and symptom focused rumination) ( r =0.60, 0.59, 0.66). Learning value doubt was positively correlated with rumination ( r =0.15) and its three dimensions ( r =0.07, 0.13, 0.19) ( P <0.05).The symptom focused rumination (effect size=0.09, 95% CI =0.06-0.11) and brooding (effect size=-0.07, 95% CI =-0.09--0.04) dimensions partially mediated the relationship between life events and learning value doubt. In the two influential pathways, symptom focused rumination exerts a stronger impact, and the difference was statistically significant (effect size=0.15, 95% CI =0.11- 0.20 , excluding 0) ( P <0.05).@*Conclusions@#Life events experienced by junior high school students can positively predict learning value doubt through symptom focused rumination, and negatively predict learning value doubt through brooding. Active attention should be paid to the mental health status of junior high school students, intervene promptly when they experience life events, reduce symptom based rumination, and improve their learning enthusiasm.

ABSTRACT

In order to build a global community of health for all, it is necessary to deeply understand the influencing factors of cross-cultural communication between medical professionals and patients. Factors such as different health beliefs, cultural values and communication mediators influence cross-cultural communication between medical professionals and patients, and then affect the medical satisfaction and treatment compliance. Medical education should adopt the learning concept of constructivism, advocate maintaining a humble cultural attitude, incorporate more patient perspectives and adopt cross-cultural teaching mode to improve the cross-cultural communication competence of medical students and medical staff, so as to establish a relationship based on communication and understanding.

ABSTRACT

@#Embryology is a critical subdiscipline in medical education, focusing on human body organ development and providing a foundation for understanding developmental anatomy. However, traditional teaching methods using static 2D graphics in textbooks may hinder students’ comprehension of the complex 3D embryonic growth processes. To address this, multimedia approaches, such as animations, videos, and interactive tools, have been explored for effective embryology education. This scoping review identifies five key elements of successful multimedia teaching in embryology: multimodal integrated instructional content, cognitive load-reduction strategies, cognitive engagement and physical interactivity, learner-controlled multimedia instruction, and development of tacit knowledge. These strategies promote active learning, enhance students’ understanding, and foster critical thinking skills. Future research should focus on evaluating the impact of multimedia approaches on students’ engagement, attitudes, and competency development. Embracing multimedia in embryology education can improve medical students’ clinical understanding and support effective medical practice.
