RESUMO

Introdução: A comunicação é reconhecida como uma habilidade central por vários órgãos reguladores internacionais da educação médica. O ensino específico de habilidades de comunicação é fundamental para melhorar a comunicação dos médicos. As técnicas experienciais mostraram superioridade em comparação com os modelos tradicionais. A utilização de consultas reais ajuda os estudantes a visualizar melhor as suas competências de entrevista e a refletir sobre elas. Com os avanços da tecnologia, o uso de consultas médicas gravadas em vídeo tornou-se a abordagem padrão para o ensino da comunicação. No entanto, a eficácia dessa técnica depende do envolvimento ativo dos estudantes. As suas contribuições e comentários dos pares sobre a consulta gravada são essenciais para a aprendizagem. Contudo, a perspectiva do estudante sobre a utilidade dessa abordagem educativa recebeu pouca atenção. Objetivos: Compreender a percepção da aprendizagem dos residentes de medicina de família e comunidade resultante da atividade de vídeo feedback na sua formação profissional. Métodos: Estudo exploratório, qualitativo, realizado com residentes do primeiro ano de medicina de família e comunidade de um programa de residência estabelecido em São Paulo, Brasil. Os participantes foram entrevistados após as sessões educativas, que foram analisadas por meio de análise temática reflexiva. Resultados: A autopercepção de sua prática, o aprendizado de habilidades de comunicação e os ganhos afetivos foram identificados pelos participantes como pontos de aprendizado derivados da atividade de vídeo feedback. Além disso, sobre o aprendizado de habilidades específicas de comunicação, eles mencionaram comunicação não-verbal e verbal, conexões entre teoria e prática, estrutura de consulta e oportunidades para cristalizar conhecimentos. Os ganhos afetivos incluíram sentir-se parte de um grupo, melhora da autoestima, superação de inseguranças, percepção de consultas mais efetivas, reforço do gosto pelo trabalho e reconhecer a necessidade de mais aprendizado. Conclusões: Os ganhos de aprendizagem identificados em nosso estudo levaram a uma experiência de humanidade compartilhada, que permite aos participantes serem mais efetivos técnica e afetivamente com seus pacientes. Além disso, identificamos que a atividade educativa de vídeo feedback pode ser utilizada para outros possíveis fins educacionais além do ensino da comunicação.


Introduction: Communication is recognized as a central skill by various international medical education regulatory bodies. Specific teaching on communication skills is important to enhance doctors' communication. Experiential techniques appear to be superior compared to traditional models. Real-life consultation helps trainees visualize their interview skills and reflect on them. Upgraded by technology, the use of video-recorded medical visits became the standard approach for communication teaching. However, the effectiveness pf this technique relies on trainees' active involvement. Their inputs and peer feedback on the recorded consultation are essential to learning. Despite its importance, their perspective on the usefulness of video feedback in medical education has received limited attention. Objective: To understand the perception of learning among general practice trainees as a result of the video feedback activity in their vocational training. Methods: An exploratory, qualitative study, conducted with first-year general practice trainees from an established training program in São Paulo, Brazil. Participants were interviewed after educational session, which were analyzed using reflexive thematic analysis. Results: Self-perception of their practice, communication skills learning, and affective gains were identified by participants as learning points derived from the video feedback activity. Furthermore, for specific communication skills learning, they mentioned nonverbal and verbal communication, theory and practice connections, consultation structure and opportunities for crystallizing knowledge. Affective gains included feeling part of a group, improving self-esteem, overcoming insecurities, perception of more effective consultations, reinforcing fondness for their work, and need for more learning. Conclusions: The learning gains identified in our study led to an experience of common humanity, which allowed participants to be more technically and affectively effective with their patients. Also, we identified that the video feedback educational activity can be used for other possible educational purposes, beyond the teaching of communication.

RESUMO

Antecedentes: La escala Teacher Emotion Inventory (TEI) es un instrumento que evalúa emociones discretas experimentadas por el profesorado en el proceso de enseñanza-aprendizaje. El objetivo de este estudio es examinar las propiedades psicométricas de la versión breve española de la escala Teacher Emotion Inventory (TEI-BSV) en una muestra de 567 profesores (65.5% son mujeres), con edades comprendidas entre 25 y 65 años (M = 46.04; DT = 9.09). Método: Tras su adaptación mediante traducción inversa, el profesorado completó una batería que incluía el TEI-BSV, un cuestionario de inteligencia emocional, dos escalas de bienestar subjetivo, una escala sobre burnout y una escala sobre engagement. Resultados: Los resultados mostraron una consistencia interna adecuada de las subescalas del TEI-BSV. Los análisis factoriales (exploratorio y confirmatorio) proporcionaron pruebas de que el TEI-BSV tiene una estructura de cuatro factores con un buen ajuste, frente a la estructura de cinco factores original. Se han hallado evidencias de validez convergente, así como de validez criterial e incremental del TEI-BSV. Conclusiones: el TEI-BSV podría ser una herramienta útil para la evaluación ecológica de las emociones discretas del profesorado en su contexto laboral.(AU)


Background: The Teacher Emotion Inventory (TEI) scale is an instrument that evaluates discrete emotions experienced by teachers in the teaching-learning process. The aim of this study was to examine the psychometric properties of the brief Spanish version of the Teacher Emotion Inventory scale (TEI-BSV) using a sample of 567 teachers (65.5% women), aged between 25 and 65 years (M= 46.04; SD= 9.09). Methods: After adaptation through back-translation, the teachers com-pleted a battery of tests included in the TEI-BSV: an emotional intelli-gence questionnaire, two subjective well-being scales, a burnout scale and a scale on engagement. Results: The data revealed adequate internal consistency of the TEI-BSV subscales, and exploratory and confirma-tory factor analyses provided evidence that the TEI-BSV has a four-factor structure with good adjustment, as opposed to the original five-factor structure proposed. There was evidence of convergent validity of the TEI-BSV, as well as criterion and incremental validity. Conclusions: The TEI-BSV could be a useful instrument for the ecological assess-ment of teachers' discrete emotions in the context of their workplace.(AU)

RESUMO

Russell bodies (RBs) are round eosinophilic intracytoplasmic inclusions formed by condensed immunoglobulins in mature plasma cells, which are called Mott cells. These cells are rarely found in the gastric tract, with even less cases reported in the colorectal region. There are still many questions about this event, as it is still unknown the relationship between the agents reported of increasing the probability of appearance of these cells and the generation of RBs. In this case report we describe the fifth patient presenting an infiltration of Mott cells in a colorectal polyp, being the second case with a monoclonal origin without a neoplastic cause, and the first one monoclonal for lambda. A comparison with previously similar reported cases is also done, and a possible etiopathogenic hypothesis proposed. (AU)


Los cuerpos de Russell (RB) son inclusiones intracitoplasmáticas eosinofílicas redondas formadas por inmunoglobulinas condensadas en las células plasmáticas maduras, que se denominan células de Mott. Estas células rara vez se encuentran en el tracto gástrico, y son aún más infrecuentes en la región colorrectal. Actualmente hay muchas dudas sobre este evento, ya que se desconoce la relación entre los agentes causantes de aumentar la probabilidad de aparición tanto de estas células como de la de RB. En este caso describimos al quinto paciente con un pólipo colorrectal, localizado en el tracto colorrectal e infiltrado por células de Mott, siendo el segundo caso de origen monoclonal sin causa neoplásica y el primero monoclonal para lambda. También se hace una comparación con casos similares previamente reportados y se propone una hipótesis etiopatogénica. (AU)

RESUMO

La esofagitis disecante superficial (EDS) es una entidad infrecuente que se caracteriza endoscópicamente por el desprendimiento de las capas superficiales del epitelio esofágico e, histológicamente, por el aspecto bitonal del epitelio escamoso esofágico secundario a la necrosis de los estratos más superficiales. La etiología es desconocida, aunque se ha asociado con la ingesta de determinados fármacos, enfermedades autoinmunes, estasis esofágica y procedimientos endoscópicos. Presentamos dos casos: uno de ellos acontece en una mujer tras un episodio de disfagia abrupta y el segundo en un varón con comorbilidades y clínica de dolor epigástrico. La EDS es una patología que hay que considerar en su adecuado contexto clínico y endoscópico, ya que su curso es autolimitado en comparación con otras entidades de evolución tórpida o que precisan un tratamiento específico. (AU)


Esophagitis dissecans superficialis (EDS) is a rare disease characterized by sloughing of the superficial esophageal mucosa and, histologically, by the bitonal appearance of the squamous epithelium secondary to necrosis of the most superficial layers. Etiology is uncertain, however, it has been associated with some medications, autoimmune diseases, esophageal stasis and endoscopic procedures. Here, two cases are presented, one of them which appeared in a woman after an episode of dysphagia and another one which occurred to a man with comorbidities and epigastric pain. This entity should be considered due to its self-limiting clinical course, compared to other entities with a more torpid evolution or that require more specific treatment. (AU)

RESUMO

Introducción: En modelos de producción vocal que emplean estructuras de resorte-masa-amortiguador, la precisión en la determinación de coeficientes de amortiguamiento que se asemejen a las características fisiológicas de las cuerdas vocales es crucial, teniendo en cuenta posibles variaciones en la representación de la viscoelasticidad. Objetivo: Este estudio tiene como objetivo realizar un ajuste paramétrico de un modelo de producción vocal basado en un sistema de resorte-masa-amortiguador que incorpora interacción con la presión subglótica, con el fin de modelar de manera precisa las fuerzas de colisión ejercidas por las cuerdas vocales durante la fonación. Método: Se utilizó un algoritmo de búsqueda metaheurística para la síntesis paramétrica. El algoritmo se aplicó a los coeficientes de elasticidad c1 y c2, así como a los coeficientes de amortiguamiento ε1 y ε2, que se correlacionan directamente con las matrices de masa del modelo. Esto facilita el ajuste de la composición de las cuerdas para lograr un comportamiento fisiológico deseado. Resultados: El comportamiento del sistema vocal para cada ciclo de simulación se comparó con un estándar predefinido en condiciones normales. El algoritmo determinó el punto final de la simulación evaluando las discrepancias entre características clave de las señales obtenidas y las deseadas. Conclusión: El ajuste paramétrico permitió la aproximación del comportamiento fisiológico de la producción vocal, proporcionando estimaciones de las fuerzas de impacto experimentadas por las cuerdas vocales durante la fonación.


Introduction: In vocal production models employing spring-mass-damper frameworks, precision in determining damping coefficients that align with physiological vocal fold characteristics is crucial, accounting for potential variations in the representation of viscosity-elasticity properties. Objective: This study aims to conduct a parametric fitting of a vocal production model based on a mass-spring-damper system incorporating subglottic pressure interaction, with the purpose of accurately modeling the collision forces exerted by vocal folds during phonation. Method: A metaheuristic search algorithm was employed for parametric synthesis. The algorithm was applied to elasticity coefficients c1 and c2, as well as damping coefficients ε1 and ε2, which directly correlate with the mass matrices of the model. This facilitates the adjustment of fold composition to achieve desired physiological behavior. Results: The vocal system's behavior for each simulation cycle was compared to a predefined standard under normal conditions. The algorithm determined the simulation endpoint by evaluating discrepancies between key features of the obtained signals and the desired ones. Conclusion: Parametric fitting enabled the approximation of physiological vocal production behavior, providing estimates of the impact forces experienced by vocal folds during phonation.

RESUMO

Within bioplastics, natural poly(3-hydroxybutyrate) (PHB) stands out as fully biocompatible and biodegradable, even in marine environments; however, its high isotacticity and crystallinity limits its mechanical properties and hence its applications. PHB can also be synthesized with different tacticities via a catalytic ring-opening polymerization (ROP) of rac-ß-butyrolactone (BBL), paving the way to PHB with better thermomechanical and processability properties. In this work, the catalyst family is extended based on aluminum phenoxy-imine methyl catalyst [AlMeL2], that reveals efficient in the ROP of BBL, to the halogeno analogous complex [AlClL2]. As well, the impact on the ROP mechanism of different initiators is further explored with a particular focus in dimethylaminopyridine (DMAP), a hardly studied initiator for the ROP of BBL. A thorough mechanistic study is performed that evidences the presence of two concomitant DMAP-mediated mechanisms, that lead to either a DMAP or a crotonate end-capping group. Besides, in order to increase the possibilities of PHB post-polymerization functionalization, the introduction of a side-chain functionality is explored, establishing the copolymerization of BBL with ß-allyloxymethylene propiolactone (BPLOAll), resulting in well-defined P(BBL-co-BPLOAll) copolymers.

RESUMO

Interventions to address polypharmacy in community-dwelling older adults often focus on medication-related outcomes. The aim was to explore the impact of multidisciplinary interventions to manage polypharmacy on clinical outcomes for community-dwelling older adults. This systematic review and meta-analysis included randomized controlled trials (RCTs) on interventions by at least a pharmacist and a physician, indexed in MEDLINE, EMBASE or CENTRAL up to January 2023. Evidence certainty was assessed using the GRADE approach. Seventeen RCTs were included. Fifteen were rated as 'high' risk of bias. No relevant benefits were found in functional and cognitive status (primary outcomes), falls, mortality, quality of life, patient satisfaction, hospital admissions, emergency department or primary care visits. Interventions reduced medication costs, improved medication appropriateness (odds ratio [OR] 0.39), reduced number of medications (mean difference [MD] -0.57), resolved medication-related problems (MD -0.45), and improved medication adherence (relative risk [RR] 1.14). There was a low or very low certainty of the evidence for most outcomes. Multidisciplinary interventions to address polypharmacy appear effective in improving multiple dimensions of medication use. However, evidence for corresponding improvements in functional or cognitive status is scarce. New efficient models of multidisciplinary interventions to address polypharmacy impacting clinical outcomes should be explored.

RESUMO

Muscle weakness has been associated to insulin resistance and metabolic syndrome in the general population. However, it is still unclear whether this association is maintained in older adults. This study investigated correlations between low handgrip strength (HGS) and metabolic syndrome, or some of its components, in older adults through a systematic review of the literature. Searches were conducted in the Virtual Health Library Regional Portal, Scopus, Cochrane, Embase, MEDLINE/ PubMed, SciELO, and Web of Science databases for relevant studiesinvestigating muscle weakness (measured by hand dynamometer) and metabolic syndrome or its components in older adult populations, published up to September 2023. From the 2050 references initially identified, 20 studies, comprising a total of 31,264 older adults of both genders, completely met the inclusion/exclusion criteria. Eighteen studies showed that lower HGS was associated with metabolic syndrome or some of its risk factors, such as abdominal obesity, hyperglycemia, insulin resistance, dyslipidemia, or high blood pressure. Two studies found that older men with high blood pressure had increased HGS. Most studies included in this systematic review revealed a significant correlation between reduced HGS and metabolic syndrome or some of its components, especially abdominal obesity and insulin resistance. We conclude that below-average HGS can be associated with metabolic syndrome in older adults.

RESUMO

OBJECTIVE: Therapy and vocal rehabilitation in laryngeal cancer impact patients' quality of life. The objective of this study was to evaluate the evolution of the quality of life of patients with laryngeal cancer submitted to total laryngectomy and using electrolarynx. METHODS: This is an observational study with a cross-sectional design and a quantitative approach. It was conducted between April 2022 and January 2023 in a Brazilian cancer hospital. For data collection, a quality of life questionnaire, validated for patients with head and neck cancer at the University of Washington, was applied in two phases: from 7 days after total laryngectomy and, subsequently, from 70 days after surgery using electronic larynx for at least 60 days. The inclusion criteria were patients undergoing total laryngectomy included on the Aldenora Bello Cancer Hospital's election list to receive the electronic larynx. Patients who did not sign the informed consent form were not included. RESULTS: The sample consisted of 31 patients, of which approximately 84% were men and approximately 93% at the age of 50 years or older. When comparing the phases, it is possible to observe that the item speech had the greatest progress, while chewing had the least. Only the item recreation, swallowing, taste, and saliva did not show any statistical significance. The score for the general quality of life questions increased. CONCLUSION: Electronic larynx is a viable and useful method of voice rehabilitation. Our data suggest that the use of the electrolarynx as a postlaryngectomy method of verbal communication is responsible for positive effects on patients' quality of life.

RESUMO

Asthma and obstructive sleep apnea (OSA) are common respiratory disorders. They share characteristics such as airway obstruction, poor sleep quality, and low quality of life. They are often present as comorbidities, along with obesity, gastroesophageal reflux disease (GERD), and allergic rhinitis (AR), which impacts the disease's control. In recent years, there has been discussion about the association between these conditions and their pathophysiological and clinical consequences, resulting in worse health outcomes, increased healthcare resource consumption, prolonged hospital stays, and increased morbidity and mortality. Some studies demonstrate that treatment with continuous positive airway pressure (CPAP) can have a beneficial effect on both pathologies. This review summarizes the existing evidence of the association between asthma and OSA at their pathophysiological, epidemiological, clinical, and therapeutic levels. It intends to raise awareness among healthcare professionals about these conditions and the need for further research.

RESUMO

Growth at the shoot apical meristem (SAM) is essential for shoot architecture construction. The phytohormones gibberellins (GA) play a pivotal role in coordinating plant growth, but their role in the SAM remains mostly unknown. Here, we developed a ratiometric GA signaling biosensor by engineering one of the DELLA proteins, to suppress its master regulatory function in GA transcriptional responses while preserving its degradation upon GA sensing. We demonstrate that this degradation-based biosensor accurately reports on cellular changes in GA levels and perception during development. We used this biosensor to map GA signaling activity in the SAM. We show that high GA signaling is found primarily in cells located between organ primordia that are the precursors of internodes. By gain- and loss-of-function approaches, we further demonstrate that GAs regulate cell division plane orientation to establish the typical cellular organization of internodes, thus contributing to internode specification in the SAM.

RESUMO

BACKGROUND: Triatoma infestans, Triatoma brasiliensis, Triatoma pseudomaculata and Rhodnius prolixus are vectors of Trypanosoma cruzi, the etiological agent of Chagas disease. Chickens serve as an important blood food source for triatomines. This study aimed to assess the insecticidal activity of fluralaner (Exzolt®) administered to chickens against triatomines (R. prolixus, T. infestans, T. brasiliensis and T. pseudomaculata). METHODS: Twelve non-breed chickens (Gallus gallus domesticus) were randomized based on weight into three groups: negative control (n = 4); a single dose of 0.5 mg/kg fluralaner (Exzolt®) (n = 4); two doses of 0.5 mg/kg fluralaner (Exzolt®) (n = 4). Nymphs of 3rd, 4th and 5th instars of R. prolixus, T. infestans, T. brasiliensis and T. pseudomaculata (all n = 10) were allowed to feed on chickens before treatment, and at intervals of 1, 7, 14, 21, 28, 35 and 56 days after treatment, with insect mortality determined. RESULTS: Treatment with two doses of fluralaner showed higher insecticidal efficacy against R. prolixus, T. infestans and T. brasiliensis compared to the single-dose treatment. Similar insecticidal efficacy was observed for T. pseudomaculata for one and two doses of fluralaner. Insecticidal activity of fluralaner (Exzolt®) against triatomine bugs was noted up to 21 and 28 days after treatment with one and two doses of fluralaner, respectively. CONCLUSIONS: The results demonstrate that treatment of chickens with fluralaner (Exzolt®) induces insecticidal activity against triatomines for up to 28 days post-treatment, suggesting its potential use as a control strategy for Chagas disease in endemic areas.

RESUMO

BACKGROUND: In recent years, the use of artificial intelligence (AI) in education has increased worldwide. The launch of the ChatGPT-3 posed great challenges for higher education, given its popularity among university students. The present study aimed to analyze the attitudes of university students toward the use of ChatGPTs in their academic activities. METHOD: This study was oriented toward a quantitative approach and had a nonexperimental design. An online survey was administered to the 499 participants. RESULTS: The findings of this study revealed a significant association between various factors and attitudes toward the use of the ChatGPT. The higher beta coefficients for responsible use (ß=0.806***), the intention to use frequently (ß=0.509***), and acceptance (ß=0.441***) suggested that these are the strongest predictors of a positive attitude toward ChatGPT. The presence of positive emotions (ß=0.418***) also plays a significant role. Conversely, risk (ß=-0.104**) and boredom (ß=-0.145**) demonstrate a negative yet less decisive influence. These results provide an enhanced understanding of how students perceive and utilize ChatGPTs, supporting a unified theory of user behavior in educational technology contexts. CONCLUSION: Ease of use, intention to use frequently, acceptance, and intention to verify information influenced the behavioral intention to use ChatGPT responsibly. On the one hand, this study provides suggestions for HEIs to improve their educational curricula to take advantage of the potential benefits of AI and contribute to AI literacy.

RESUMO

Toxoplasmosis affects about one-third of the world's population. The disease treatment methods pose several side effects and do not efficiently eliminate the parasite, making the search for new therapeutic approaches necessary. We aimed to assess the anti-Toxoplasma gondii activity of four Copaifera oleoresins (ORs) and two isolated diterpene acids, named ent-kaurenoic and ent-polyalthic acid. We used HeLa cells as an experimental model of toxoplasmosis. Uninfected and infected HeLa cells were submitted to the treatments, and the parasite intracellular proliferation, cytokine levels and ROS production were measured. Also, tachyzoites were pre-treated and the parasite invasion was determined. Finally, an in silico analysis was performed to identify potential parasite targets. Our data show that the non-cytotoxic concentrations of ORs and diterpene acids controlled the invasion and proliferation of T. gondii in HeLa cells, thus highlighting the possible direct action on parasites. In addition, some compounds tested controlled parasite proliferation in an irreversible manner. An additional and non-exclusive mechanism of action involves the modulation of host cell components, by affecting the upregulation of the IL-6. Additionally, molecular docking suggested that ent-polyalthic acid has a high affinity for the active site of the TgCDPK1 protein. Copaifera ORs have great antiparasitic activity against T. gondii, and this effect can be partially explained by the presence of the isolated compounds ent-kaurenoic and ent-polyalthic acid.
