The let-7b-5p, miR-326, and miR-125a-3p are associated with left ventricular systolic dysfunction in post-myocardial infarction.

Background: Acute ST-elevation myocardial infarction (STEMI) can lead to adverse cardiac remodeling, resulting in left ventricular systolic dysfunction (LVSd) and heart failure. Epigenetic regulators, such as microRNAs, may be involved in the physiopathology of LVSd. Objective: This study explored microRNAs in peripheral blood mononuclear cells (PBMC) of post-myocardial infarction patients with LVSd. Methods: Post-STEMI patients were grouped as having (LVSd, n = 9) or not LVSd (non-LVSd, n = 16). The expression of 61 microRNAs was analyzed in PBMC by RT-qPCR and the differentially expressed microRNAs were identified. Principal Component Analysis stratified the microRNAs based on the development of dysfunction. Predictive variables of LVSd were investigated through logistic regression analysis. A system biology approach was used to explore the regulatory molecular network of the disease and an enrichment analysis was performed. Results: The let-7b-5p (AUC: 0.807; 95% CI: 0.63-0.98; p = 0.013), miR-125a-3p (AUC: 0.800; 95% CI: 0.61-0.99; p = 0.036) and miR-326 (AUC: 0.783; 95% CI: 0.54-1.00; p = 0.028) were upregulated in LVSd (p < 0.05) and discriminated LVSd from non-LVSd. Multivariate logistic regression analysis showed let-7b-5p (OR: 16.00; 95% CI: 1.54-166.05; p = 0.020) and miR-326 (OR: 28.00; 95% CI: 2.42-323.70; p = 0.008) as predictors of LVSd. The enrichment analysis revealed association of the targets of these three microRNAs with immunological response, cell-cell adhesion, and cardiac changes. Conclusion: LVSd alters the expression of let-7b-5p, miR-326, and miR-125a-3p in PBMC from post-STEMI, indicating their potential involvement in the cardiac dysfunction physiopathology and highlighting these miRNAs as possible LVSd biomarkers.

Efeito da idade no equilíbrio corporal e nos resultados do vídeo teste do impulso cefálico em pacientes com insuficiência cardíaca / Effect of age on body balance and on the results of the video head impulse test in patients with heart failure

RESUMO Objetivo verificar se existe associação entre a avaliação clínica do equilíbrio e o ganho do reflexo vestíbulo-ocular com o avanço da idade em pacientes com insuficiência cardíaca. Métodos estudo transversal analítico-descritivo, de caráter observacional, que incluiu pacientes com diagnóstico de insuficiência cardíaca, divididos em dois grupos, por idade (G1, menos de 60 anos e G2, 60 anos ou mais). Os pacientes foram avaliados por meio de anamnese, avaliação cardiológica, avaliação clínica do equilíbrio corporal (triagem da função cerebelar e avaliação do equilíbrio estático e dinâmico) e instrumental da função vestibular (Video Head Impulse Test-vHIT). Os achados obtidos foram descritos e comparados por meio de análise estatística inferencial. Resultados foram avaliados 34 pacientes com média de idade de 55 anos e 9 meses, a maioria homens (71,49%). Não houve associação do ganho do reflexo vestíbulo-ocular, simetria dos canais semicirculares e avaliações do equilíbrio corporal com o avanço da idade. Observaram-se associações entre os resultados da prova de Unterberger-Fukuda com o ganho do reflexo vestíbulo-ocular do canal semicircular lateral direito e posterior esquerdo e com os percentuais de simetria dos canais semicirculares anteriores para os pacientes do Grupo 2. Para os indivíduos do Grupo 1, foi observada associação entre os resultados da prova de Unterberger-Fukuda com os valores de simetria dos canais semicirculares anteriores e do ganho de reflexo vestíbulo-ocular dos canais semicirculares anterior esquerdo e posterior direito. Conclusão não houve associação entre os resultados da avaliação clínica do equilíbrio corporal e dos achados do vHIT com o avanço da idade, em pacientes com insuficiência cardíaca. Entretanto, observou-se diferença entre o ganho do reflexo vestíbulo-ocular específico para alguns canais semicirculares, com maiores índices de alteração na prova de equilíbrio dinâmico, em ambos os grupos. Os resultados dos testes aplicados permitiram caracterizar o predomínio da hipofunção vestibular crônica de origem periférica nos pacientes com insuficiência cardíaca, independentemente da faixa etária.

ABSTRACT Purpose to verify whether there is an association between the clinical assessment of balance and the gain in the vestibulo-ocular reflex with advancing age in patients with heart failure. Methods analytical-descriptive, observational cross-sectional study, which included patients diagnosed with heart failure, divided into two groups by age (G1, under 60 years old and G2, 60 years old or older). The patients were evaluated through anamnesis, cardiac assessment, clinical assessment of body balance (cerebellar function screening and assessment of static and dynamic balance) and instrumental assessment of vestibular function (Video Head Impulse Test-vHIT). The findings were described and compared through inferential statistical analysis. Results 34 patients with a mean age of 55 years and 9 months, mostly men (71.49%). There was no association between vestibulo-ocular reflex gain, symmetry of the semicircular canals and body balance with advancing age. Associations were observed between the results of the Unterberger-Fukuda test with the gain in the vestibulo-ocular reflex of the right lateral and left posterior semicircular canals and with the percentages of symmetry of the anterior semicircular canals for patients in Group 2. In Group 1, an association was observed between the results of the Unterberger-Fukuda test and the symmetry values of the anterior semicircular canals and the gain in the vestibulo-ocular reflex of the left anterior and right posterior semicircular canals. Conclusion there was no association between the results of the clinical assessment of body balance and the vHIT findings with advancing age in patients with heart failure. However, there was a difference between the gain of the specific vestibulo-ocular reflex for some semicircular canals, with higher rates of alteration in the dynamic balance test, in both groups. The results of the applied tests allowed characterize the predominance of chronic vestibular hypofunction of peripheral origin in patients with heart failure, regardless of age group.

Lack of Association between Inadequate Micronutrient Intake and Prognosis in Outpatients with Heart Failure.

Inadequate nutrient intake can lead to worse outcomes in patients with heart failure (HF). This prospective cohort study aimed to assess the prevalence of inadequate micronutrient intake and their association with prognosis in 121 adult and elderly outpatients with HF. Habitual micronutrient intake was evaluated using 24-h dietary recalls (minimum 2 and maximum 6). Participants were grouped into moderate (n = 67) and high (n = 54) micronutrient deficiency groups, according to the individual assessment of each micronutrient intake. Patients' sociodemographic, clinical, and anthropometric data and clinical outcomes (hospitalization and mortality) within 24 months were collected. Overall and event-free survival rates were calculated using Kaplan-Meier estimates, and curves were compared using the log-rank test. The death risk rate (hazard ratio (HR)) was calculated using Cox's univariate model. The rate of inadequate intake was 100% for vitamins B1 and D and above 80% for vitamins B2, B9, and E, calcium, magnesium, and copper. No differences in overall survival and event-free survival were observed between groups of HF outpatients with moderate and high micronutrient deficiencies (HR = 0.94 (CI = 0.36-2.48), p = 0.91, and HR = 1.63 (CI = 0.68-3.92), p = 0.26, respectively), as well as when the inadequacy of each micronutrient intake was evaluated alone (all p > 0.05). In conclusion, a high prevalence of inadequate micronutrient intake was observed in outpatients with HF. Inadequate micronutrient intake was not associated with hospitalization and mortality in this group of patients.

Biomarkers of Zinc and Copper Status and Associated Factors in Outpatients with Ischemic and Non-Ischemic Heart Failure.

Background: Few studies have explored the impact of ischemic and non-ischemic etiologies of heart failure and other factors associated with heart failure on zinc and copper status. This study examined zinc and copper status in 80 outpatients with ischemic (n = 36) and non-ischemic (n = 44) heart failure and associations with biodemographic, clinical, biochemical, and nutritional parameters.Materials: Biomarkers of plasma zinc and copper, copper-zinc ratio, 24-h urinary zinc excretion, ceruloplasmin, and dietary intake of zinc and copper were assessed. Plasma zinc and copper and urinary zinc were measured by inductively coupled plasma mass spectrometry (ICP-MS).Results: Patients with ischemic heart failure showed lower dietary zinc intake and higher dietary copper intake (both p = 0.02). Zinc and copper in plasma, copper-zinc ratio, ceruloplasmin, and 24-h urinary zinc excretion showed no statistical differences between the groups (all p ≥ 0.05). An inverse association was found between age (ß =-0.001; p = 0.005) and the use of diuretics (ß = -0.047; p = 0.013) and plasma zinc. Copper levels in plasma (ß = 0.001; p < 0.001), and albumin (ß = 0.090; p<0.001) were directly associated with plasma zinc. A positive association was found between ceruloplasmin (ß = 0.011; p < 0.001), gamma-glutamyl transferase (ß = 0.001; p < 0.001), albumin (ß = 0.077; p = 0.001), and high-sensitivity c-reactive protein (ß = 0.001; p = 0.024) and plasma copper.Conclusion: Zinc and copper biomarkers in clinically stable patients with heart failure did not seem to be responsive to the differences in zinc and copper intake observed in this study, regardless of heart failure etiology. The predictors of plasma zinc and copper levels related to oxidative stress and inflammation should be monitored in heart failure clinical practice.

Vitamin D status and predictors of 25-hydroxyvitamin D levels in patients with heart failure living in a sunny region.

INTRODUCTION: Aims: hypovitaminosis D has frequently been identified in patients with heart failure (HF). However, few studies have been conducted in regions with high solar incidence. Therefore, this study aimed to evaluate vitamin D status and predictors of 25-hydroxyvitamin D (25(OH)D) levels in patients with HF living in a sunny region (5 °- 6 °S). Methods: this cross-sectional study enrolled 70 patients with HF. Biodemographic, clinical, biochemical, dietary, and sun exposure data were collected, and 25(OH)D levels were measured. Results: the mean 25(OH)D level was 40.1 (12.4) ng/mL, and 24.3 % (95 % CI: 14.2-33.8) of patients with HF had hypovitaminosis D (25(OH)D < 30 ng/mL). Female patients (p = 0.001), those with ischemic etiology (p = 0.03) and those with high parathyroid hormone levels (> 67 pg/mL) (p = 0.034) were more likely to present hypovitaminosis D. Higher 25(OH)D levels were observed in men than in women (ß = 7.78, p = 0.005) and in patients with HF in New York Heart Association (NHYA) functional class I when compared to those in class III/IV (ß = 8.23, p = 0.032). Conclusions: the majority of patients with HF had sufficient 25(OH)D levels. Sex and functional classification were identified as independent predictors of 25(OH)D levels. These results highlight the need for increased monitoring of vitamin D status among female patients with heart failure and those with more severe symptoms.

INTRODUCCIÓN: Objetivos: la hipovitaminosis D se ha identificado con frecuencia en pacientes con insuficiencia cardíaca (IC). Sin embargo, pocos estudios se han realizado en regiones con una alta exposición solar. Por lo tanto, este estudio tuvo como objetivo evaluar el estado de la vitamina D y los predictores de los niveles de 25-hidroxivitamina D (25(OH)D) en pacientes con IC que viven en una región soleada (5 °-6 °S). Métodos: este estudio transversal incluyó a 70 pacientes con IC. Se recopilaron datos biodemográficos, clínicos, bioquímicos, dietéticos y de exposición solar, y se midieron los niveles de 25(OH)D. Resultados: el nivel medio de 25(OH)D fue de 40,1 (12,4) ng/mL y el 24,3 % (IC 95 %: 14,2-33,8) de los pacientes con IC tenían hipovitaminosis D (25(OH)D < 30 ng/mL. Las pacientes mujeres (p = 0,001), aquellos con IC de etiología isquémica (p = 0,03) y aquellos otros pacientes con niveles altos de hormona paratiroidea (> 67 pg/mL) (p = 0,034) tenían más probabilidades de presentar hipovitaminosis D. Se observaron niveles más altos de 25(OH)D en los hombres que en las mujeres (ß = 7,78, p = 0,005), y en los pacientes con IC de clase funcional I de la New York Heart Association (NHYA) que en los de clase III/IV (ß = 8,23, p = 0,032). Conclusiones: la mayoría de los pacientes con IC tenían niveles suficientes de 25(OH)D. El sexo y la clasificación funcional se identificaron como predictores independientes de los niveles de 25(OH)D. Estos resultados destacan la necesidad de un mayor control del estado de la vitamina D entre las mujeres con insuficiencia cardíaca y los pacientes con síntomas más graves.

Competency matrix related to Covid-19: contributions from students and residents / Matriz de competência relacionada à Covid-19: contribuições de estudantes e residentes

Abstract: Introduction: Competency-based education has been discussed under the new perspective of the COVID-19 pandemic. The need for social distancing had effects on student activities and educational institutions needed to reflect and redesign the teaching-learning process. It was necessary to incorporate contents related to COVID-19 into the medical training programs and to adapt the teaching tools. Therefore, it is necessary that training be mediated by a collective construction of the competency matrix with the participation of the subjects involved in the process. Objective: This project aims to present the reconstruction of the curriculum in cardiology by observing the collaboration of the students and residents. Method: Exploratory study, involving 13 undergraduate medical students and eight medical residents from the institution's cardiology program, who comprised the "Students and residents' panel". Consensus was reached among the panelists through the Delphi methodology. The first version of the matrix was prepared by the research team and sent, together with the FICF, containing 16 items aimed at COVID-19 content to be achieved at the cardiology internship and residency. The participants attributed their degree of agreement for each proposed item and after returning them, the data were tabulated, stored in an Excel spreadsheet and percentages for each item were calculated and presented in a descriptive manner. Result: The panel consisted of 19 participants. Of the 21 invited, 02 participants did not answer the online questionnaire and were excluded. The initial version of the matrix reached a consensus in the first round, with the lowest agreement rate being 71% in the internship matrix and 89.5% in the residency matrix. Both matrices showed high levels of agreement. There were no disagreements or suggestions for new items for the matrix. Conclusion: The students and residents' engagement in the pedagogical process may contribute to a better understanding of the competencies for their training and bring sustainable changes to the curriculum.

Resumo: Introdução: A educação baseada em competências vem sendo discutida sob a nova perspectiva da pandemia da Covid-19. A necessidade do distanciamento social trouxe repercussão nas atividades estudantis, e as instituições de ensino precisaram refletir e redesenhar o processo de ensino-aprendizagem. Houve a necessidade de inserção de conteúdos relacionados à Covid-19 nos programas de capacitação médica e a adaptação das ferramentas pedagógicas. Portanto, é necessário que a formação seja mediada por uma construção coletiva da matriz de competências com participação dos sujeitos envolvidos no processo. Objetivo: Este projeto visa apresentar a reconstrução da matriz de competências em cardiologia observando a colaboração do estudante e residente. Método: Trata-se de um estudo exploratório envolvendo 13 graduandos do curso de Medicina e oito residentes médicos do programa de cardiologia da instituição, os quais compuseram o "Painel de estudantes e residentes". Obteve-se o consenso entre os painelistas por meio da metodologia Delphi. A primeira versão da matriz foi elaborada pela equipe de pesquisa e enviada, com o TCLE, contendo 16 itens voltados para conteúdos sobre a Covid-19 a serem alcançados no internato e na residência em cardiologia. Os participantes atribuíram o grau de concordância a cada item proposto, sendo os dados apresentados de forma descritiva e com proporção de concordância. Resultados: O painel final foi formado por 19 integrantes. Dentre os 21 convidados, dois foram excluídos por não responderem ao questionário. A versão inicial da matriz obteve consenso na primeira rodada, sendo a menor taxa de concordância de 71% na matriz do internato e 89,5% na matriz da residência. Ambas as matrizes apresentaram índices elevados de concordância. Não houve discordâncias nem sugestões de novos itens para a matriz. Conclusão: O engajamento de estudantes e residentes no processo pedagógico pode contribuir para melhor compreensão sobre as competências para sua formação e promover mudanças sustentáveis no currículo.

Reflexões sobre a quarentena: uma estratégia de acolhimento de discentes em um grupo de mentoring / Reflections about quarantine: a strategy for undergraduate medical student reception in a mentoring group

Resumo: Introdução: Notícias sobre a pandemia de Covid-19 chegam constantemente via meios de comunicação, e, rapidamente, há elevada sobrecarga de informações e inseguranças cotidianas. Para os estudantes de Medicina, essas mudanças podem ter efeito ainda mais significativo, pois já apresentam certo grau de adoecimento e queda da qualidade de vida pelo estresse acadêmico. Nessas situações, estratégias de reflexão, fala e escuta ativa podem ser úteis para a saúde mental. Relato de experiência: Este relato apresenta, de forma descritiva, a análise reflexiva da percepção discente sobre facilidades e adversidades vivenciadas durante o distanciamento social proporcionado pela pandemia de Covid-19, bem como avalia de que modo a participação na mentoria interferiu nesse processo. Os estudantes responderam a um questionário de seis perguntas abertas sobre as experiências e a saúde mental deles. Esse questionário teve como objetivos refletir sobre o momento e compreendê-lo para melhorar a condução dos encontros do mentoring e minimizar um eventual impacto negativo na saúde mental dos discentes. Após a anuência dos participantes, por meio do Termo de Consentimento Livre e Esclarecido (TCLE) aprovado pelo Comitê de Ética em Pesquisa, as respostas foram analisadas em anonimato e coletivamente pelos próprios estudantes, de forma categorial temática, encontrando os núcleos de sentido a partir da leitura do corpus textual para identificação das unidades de análises. Discussão: Houve 12 respondentes, o que representa uma taxa de resposta de 92,3% dos estudantes aos quais foi enviado o questionário, no qual apontaram o impacto da pandemia na saúde mental, fizeram uma reflexão interior, indicaram os mecanismos adaptativos e apresentaram os aspectos da mentoria que a tornaram um ambiente seguro e de suporte. Conclusão: A análise revelou que muitos discentes estão enfrentando dificuldades de adaptação, sobretudo quanto à saúde mental, como instabilidade emocional, revolta e frustração. Todavia, relataram-se positividade, desenvolvimento de hobbies e aumento do autoconhecimento e da comunicação com familiares. Apesar das limitações dos encontros remotos, não houve prejuízos de aproveitamento do programa e alcance de seus objetivos.

Abstract: Introduction: The constant stream of news about the Covid-19 pandemic in the media has contributed to information overload and daily insecurities. For medical students, these changes can have an even more significant effect, as they already suffer a certain degree of illness and their quality of life is impaired by academic stress. In these situations, strategies for reflection, speech and active listening can be useful for mental health. Experience report: This report presents, in a descriptive way, the reflective analysis of the student's perception of the facilities and adversities experienced during the social distancing measures enforced by the Covid-19 pandemic and how participation in mentoring interfered in this process. The students answered a questionnaire of six open-ended questions about their experiences and mental health, to reflect and better understand the current situation and thus enhance the mentoring program meetings, supporting and minimizing any negative impact on the students' mental health. After informed consent was agreed by the participants and approval given by the Ethics Committee, thematic content analysis of the answers was performed anonymously and collectively by the students themselves. The core meanings were sought from reading the textual corpus, thus identifying the units of analysis. Discussion: There were twelve respondents, representing a response rate of 92.3% of the students to whom the questionnaire was sent, reporting the impact on their mental health, their inner reflections and adaptive mechanisms and mentoring as a safe environment of support. Conclusion: The analysis revealed that many students are facing difficulties in adapting, especially regarding mental health, reporting issues such as emotional instability, revolt and frustration. However, positivity, development of hobbies, increased self-knowledge and communication with family members were reported. Despite the limitations presented by the remote meetings, there were no adverse effects of using the program and achieving its objectives.

SPIKES-D: a proposal to adapt the SPIKES protocol to deliver the diagnosis of dementia.

Dementia is a life-threatening and stigmatizing condition, with devastating impacts on the patient's personal identity and caregivers. There are many barriers to an effective diagnosis disclosure of dementia, including fear of causing distress, uncertainty of diagnosis, caregivers' objection and lack of training in communication skills in undergraduate medical schools. Although some studies have been published on how to help physicians deliver an Alzheimer's disease diagnosis, no specific protocol has been published yet. The SPIKES protocol is a didactic approach designed to deliver bad news related to cancer, but it has been used globally and in a variety of clinical settings, including the teaching of communication skills to medical students and residents. It is known, however, that the cognitive impairment of Alzheimer's disease and other dementias may limit the understanding of the diagnosis' complexity; hence, a few adaptations of this model were made after reviewing the current literature on dementia diagnosis disclosure. The suggested SPIKES-D protocol seems to encompass current guidelines about the communication of the diagnosis of dementia, keeping its didactic approach on breaking bad news and helping fulfill the gaps in this topic.

A demência é uma condição incurável e estigmatizada, com impacto devastador na identidade pessoal do paciente e seus cuidadores. Existem muitas barreiras para uma adequada comunicação do diagnóstico às pessoas com demência, incluindo medo de causar estresse psicológico, incerteza do diagnóstico, objeção dos cuidadores e falta de treinamento em habilidades de comunicação nas escolas de medicina. Embora alguns artigos sobre como auxiliar a equipe médica a comunicar um diagnóstico de demência tenham sido publicados, nenhum protocolo específico foi publicado até o presente momento. O protocolo SPIKES é uma abordagem didática desenvolvida para auxiliar a comunicação de más notícias relacionadas ao câncer, mas tem sido utilizado em todo o mundo e nos mais diversos contextos clínicos, inclusive no ensino de habilidades de comunicação para estudantes e residentes de medicina. Entretanto, é sabido que o declínio cognitivo inerente à doença de Alzheimer e outras demências pode limitar a compreensão da complexidade do diagnóstico, tendo sido realizadas, portanto, algumas adaptações nesse protocolo após revisão da literatura acerca da comunicação do diagnóstico das demências. O protocolo SPIKES-D aqui sugerido parece englobar as diretrizes atuais sobre a comunicação do diagnóstico de demências, preservando seu caráter didático na comunicação de más notícias e auxiliando no preenchimento das lacunas neste tópico.

Acuracy and concordance of anthropometric indicators and body composition in heart failure / Precisão e concordância de indicadores antropométricos e composição corporal na insuficiência cardíaca

Background: Anabolic/catabolic disorder in heart failure (HF) favors cardiac cachexia, implying a reduction in HF survival. Objectives: To assess the accuracy and concordance of the diagnosis of protein malnutrition and excess fat among the anthropometric and body composition methods in individuals with HF. Method: A study of accuracy that included 60 individuals with HF. Body mass index (BMI), arm circumference (AC), triceps skinfold thickness (TST), adductor pollicis muscle thickness (APMT), arm muscle circumference (AMC) and corrected arm muscle area (cAMA). Fat free mass index (FFMI) and body fat percentage (BF%), obtained by electrical bioimpedance (EBI), were used to compare the diagnosis of protein malnutrition and excess fat. Accuracy was assessed by calculating sensitivity, specificity, positive and negative predictive value. The concordance of the EBI diagnosis and other methods was performed by the chi-square test and kappa (k) statistic, where p<0.05 was considered significant.Results: Higher frequencies of protein malnutrition were identified by cAMA and AMC, and excess fat by BF%. BMI presented low sensitivity (43%) and accuracy (38.5%), with moderate concordance (0.50). AMC sensitivity was 86%, accuracy 66.4%, and acceptable concordance (0.36) compared to FFMI. Similar percentages of moderate sensitivity and low accuracy were observed for TST and BMI.Conclusion: AMC may be useful to identify protein malnutrition and TST has not been adequate to diagnose adiposity. BMI was not sensitive to assess muscle and adipose reserve. EBI was more accurate

Workplace Based Assessment in Obstetrics and Gynecology Clerkship to Detect Learning Gaps / Avaliação Baseada em Cenários de Prática para Detectar Lacunas de Aprendizagem no Internato Médico em Ginecologia e Obstetrícia

ABSTRACT Background An outcome-based curriculum helps to communicate expectations of performance to students and clinical teachers. The Mini Clinical Evaluation Exercise (mini-CEX) is a useful tool for workplace-based formative assessment. The objective of this study was to use workplace-based assessment and student feedback to evaluate an Obstetrics and Gynecology (Ob&Gyn) clerkship curriculum. Methods A cross-sectional study was conducted with faculty members and medical students in an Ob&Gyn clerkship. The Mini-CEX was introduced into the clerkship assessment system, together with multiple choice question (MCQ) tests. This tool evaluates the history collection, physical examination, clinical judgment, professionalism and humanism, and also gives an overall score at the end of the test. At the end of the rotation, questionnaires were used to collect the students' perceptions about their skills acquisition during the program. The results of the Mini-CEX, the MCQ test, and questionnaire responses were compared, to determine the extent to which learning objectives were achieved. Results three faculty members assessed 84 medical students using the mini-CEX during the four-month clerkship. The scores for the physical examination and clinical judgment skills were lower, compared to those of the interviewing skills. Based on the students' feedback, ratings for physical examination and counseling preparation were rated as "inadequate", especially for the topic breaking bad news. The bivariate correlation between the mini-CEX skills and MCQ test scores showed a positive relationship (r = 0.27). Although they assess different skills on the Muller pyramid, there appears to be a relationship between "Knowing" and "Doing". These findings will help curriculum managers to identify important gaps in the rotation design and delivery. Based on these results, training in the skills workshop during the first month of the rotation was initiated, in addition to previous simulated training during the third year of medical course. Conclusions The introduction of the mini-CEX offers critical information to identify and refine important curriculum elements in the clinical years. Based on this, physical examination and communications skills training were initiated in the skills workshop.

RESUMO Contexto Currículo Baseado em Desfechos ajuda a comunicar as expectativas de desempenho entre alunos e professores. O Miniexercício de Avaliação Clínica (Miniex) é uma ferramenta útil para avaliação formativa no local de trabalho. O objetivo deste estudo foi usar avaliação em cenários reais de prática e feedback dos alunos para qualificar um programa de internato médico em Ginecologia e Obstetrícia (GO). Métodos Foi realizado um estudo transversal com docentes e estudantes do internato médico em GO. O Miniex foi introduzido no sistema de avaliação de estágio adicionado a testes de perguntas de múltipla escolha (MCQ). Esta ferramenta avalia a coleta de histórico, o exame físico, o julgamento clínico, o profissionalismo e o humanismo, além da escala global no final do teste. No final da rotação de quatro meses, questionários foram aplicados para coletar a percepção do aluno sobre a aquisição de habilidades durante o programa. Os resultados do Miniex, o teste de MCQ e as respostas aos questionários foram comparados para determinar a medida em que os objetivos de aprendizagem foram alcançados. Resultados Três docentes avaliaram 84 estudantes de Medicina usando Miniex ao longo do estágio de quatro meses. As pontuações médias para exame físico e habilidades de julgamento clínico foram menores em comparação com as habilidades de anamnese e aconselhamento. Com base na percepção dos alunos, o preparo para exame físico e o aconselhamento foram classificados como "inadequados", especialmente quanto à divulgação de más notícias. A correlação bivariada entre as habilidades do Miniex e os escores do teste MCQ mostrou uma relação positiva (r = 0,27). Apesar de avaliar as diferentes habilidades da pirâmide de Muller, parece haver uma relação entre "knows" e "does". Essas descobertas ajudaram os coordenadores de internato e docentes a identificar lacunas importantes no programa do estágio. Com base nesses resultados, foi iniciado um treinamento no laboratório de habilidades durante o primeiro mês de rotação para todos os alunos ingressantes, adicionado ao treinamento simulado anterior durante o terceiro ano do curso de Medicina. Conclusões A introdução do Miniex oferece informações críticas para identificar e aprimorar elementos curriculares importantes nos anos clínicos.

Chagas disease: morbidity profile in an endemic area of Northeastern Brazil.

INTRODUCTION: This study evaluated the clinical forms and manifestation severities of Chagas disease among serologically reactive individuals from Western Rio Grande do Norte (Northeastern Brazil). METHODS: This cross-sectional study included 186 adults who were evaluated using electrocardiography, echocardiography, chest radiography, and contrast radiography of the esophagus and colon. A clinical-epidemiological questionnaire was also used. RESULTS: The indeterminate, cardiac, digestive, and cardiodigestive clinical forms of Chagas disease were diagnosed in 51.6% (96/186), 32.2% (60/186), 8.1% (15/186) and 8.1% (15/186) of the participants, respectively. Heart failure (functional classes I-IV) was detected in 7.5% (14/186) of the participants, and 36.4% (24/66), 30.3% (20/66), 15.2% (10/66), 13.6% (9/66), and 4.5% (3/66) of the patients were at stage A, B1, B2, C, and D, respectively. Dilated cardiomyopathy and electrocardiographic changes were detected in 10.2% (19/186) and 48.1% (91/186) of the participants, respectively. Apical aneurysm was diagnosed in 10.8% (20/186) of the participants, and other changes in the segmental myocardial contractility of the left ventricle were diagnosed in 33.9% (63/186) of the participants. Megaesophagus (groups I-IV) was observed in 7% (13/186) of the participants, megacolon (grades 1-3) was detected in 12.9% (24/186) of the participants, and both organs were affected in 29.2% (7/24) of the megacolon cases. CONCLUSIONS: We detected various clinical forms of Chagas disease (including the digestive form). Our findings indicate that clinical symptoms alone may not be sufficient to exclude or confirm cardiac and/or digestive damage, and the number of patients with symptomatic clinical forms may be underestimated.
