Abstract Background Stroke management require rapid identification, assessment, and transport of patients to qualified health care centers. However, there is little description in the literature on the multiple challenges associated with the pre-hospital transport of suspected stroke patients. Objective To characterize the pre-hospital care provided to suspected stroke patients by the Brazilian Emergency Medical Service (SAMU in Portuguese), by means of a descriptive case study. Methods This is a descriptive study of a series of cases. Data from the SAMU regarding the responses to emergency calls from suspected stroke patients were collected. Independent reviewers confirmed the diagnostic hypothesis and all discordances were assessed using kappa statistics. Clinical data and transport times were described as frequency and proportion or central tendency and dispersion measures. Normality of continuous variable distribution was assessed using the Kolmogorov-Smirnov test. The Mann-Whitney U test was used for comparison of medians, with a 5% significance level. Results During the studied period, 556 suspected stroke patients were treated. The kappa index was 0.82 (95% CI 0.737 to 0.919) CI. In 74.7% of the cases, the symptom onset time was not recorded. The median time elapsed between the call for emergency services and the ambulance arrival was 18 minutes, and the median transport time was 38 minutes. A total of 34% of the patients were taken to referral hospitals for stroke. Conclusion This study revealed a low level of knowledge regarding the need to determine the exact time of symptom onset of suspected stroke patients. Also, the study showed the low rate of patients taken to referral hospitals. (Int J Cardiovasc Sci. 2021; [online].ahead print, PP.0-0)

ABSTRACT BACKGROUND: Instant messaging services (IMS) are widely used in medical practice. OBJECTIVE: To evaluate perceptions regarding use and usability of IMS within clinical practice and assess users’ knowledge of the ethical and legal context involved in using IMS within medical practice. DESIGN AND SETTING: Cross-sectional study conducted in different hospitals and medical institutions in Minas Gerais, Brazil. METHODS: Medical students, medical residents, primary care physicians and specialist doctors answered an online questionnaire regarding epidemiological data, graduation level and use of IMS for medical communication. Responses were collected over a five-month period and data were assessed using the IBM-SPSS software. RESULTS: 484 people answered the questionnaire: 97.0% declared that they were using IMS for medical-related purposes; 42.0%, to elucidate medical concerns every week; 75.0%, to share imaging or laboratory tests and patients’ medical records; and 90.5%, to participate in clinical case-study private groups. Moreover, only 37.0% declared that they had knowledge of the legislative aspects of use of smartphones within clinical practice. Differences in the frequency of discussion of medical concerns within the daily routine between student/residents and general practitioners/specialists, and in the frequency of image-sharing and patient-guiding/assistance between students and medical doctors, were observed. CONCLUSIONS: Our results provide reliable proof that medical doctors and students use IMS, as a tool for clinical case discussions, interactions between healthcare providers and patients, or dissemination of knowledge and information. Nonetheless, because of limitations to the ethical and legal regulations, evidence-based discussions between authorities, academics and medical institutions are needed in order to fully achieve positive outcomes from such platforms.

Resumo: Introdução: O curso de Medicina possui fatores potencialmente estressantes que podem gerar adoecimento psíquico nos alunos. Métodos curriculares alternativos ao sistema tradicional, como aAprendizagem Baseada em Problemas (ABP), podem ter impacto na saúde mentaldos discentes. O objetivo deste estudo foirealizar uma revisão sistemática de estudos que avaliaram a saúde mental de estudantes de Medicina submetidos ao método ABP. Método: Realizou-se uma busca de alta sensibilidade nas principais bases de dados científicas associadas àsaúde mental (CochraneLibrary, Medline via PubMed, Portal Regional da Biblioteca Virtual em Saúde(BVS), Eric e Embase) com inserção até 22 de setembro de 2019. Os descritos indexados e os termos de identificação foram definidos por especialistas e avaliados pelo grupo de tecnologia da informação da Universidade Estadual do Pará.Os critérios de inclusão para os estudos obtidos por meioda busca foram: artigos apresentados na íntegra, escritos em qualquer língua, publicados no período de 1998 a 2018, com foco na saúde mental de alunos do curso de Medicina submetidos ao método ABP. Excluíram-se os trabalhos que não avaliaram a saúde mental, os artigos em que a amostra não foi submetida à metodologia de ensino ABP e aqueles de revisão literária. Após a seleção, os artigos foram avaliados duplamente por revisores independentes quanto ao risco de viés e à qualidade de evidência mediante a ferramenta Robins-I. Resultados: Identificaram-se 1.261 estudos, dos quais se excluíram 1.251 conforme orientaçãodoprotocolo Prisma, restando dezartigos ao final, os quais foram sintetizados de forma descritiva. Em geral, os estudos têm mostrado que o método de ABP, em comparação com o método tradicional, promove melhor desempenho acadêmico, bem como estimula atividades práticas, fato que gera certo grau de satisfação. Conclusão: Os discentes de Medicina submetidos ao método ABP são associados a resultados adequados de aprendizado e desempenho médico-científico. Entretanto,metodologias científicas mais assertivas, baseadas em critérios metodológicos mais rigorosos,são necessárias para elucidar de forma mais abrangente os benefícios e danos dessa metodologia pedagógica.

Abstract: Introduction: Medical students are subjected to potentially stressful factors that can lead to psychological illness. Alternatives to traditional training methods, such as Problem-Based Learning (PBL), can impact on students’ mental health. The aim of this study was to carry out a systematic review of studies that evaluate the mental health of medical students submitted to the Problem-Based Learning (PBL) method. Method: A highly sensitive search was carried out in the main scientific databases associated with mental health (Cochrane Library, MEDLINE via PUBMED, Regional Health Portal (VHL), Eric and EMBASE) with inclusion up to September 22, 2019. Indexed descriptions and identification terms were defined by specialists and evaluated by the information technology group of the StateUniversity of Pará. The inclusion criteria for the study search were: articles presented in full, written in any language, published in the period from 1998 to 2018, focusing on the mental health of medical students submitted to the PBLmethod. Articles that did not assess mental health, articles in which the sample was not submitted to PBL, andreview articleswere excluded. After selection, the articles were assessed twice by independent reviewers for risk of bias and quality of evidence using the ROBINS-I tool. Results: 1261 studies were identified, of which 1251 were excluded following the PRISMA protocol, leaving a final sample of ten articles, which were descriptively summarized.In general, studies have shown that PBL, compared to traditional teaching methods, promotes better academic performance, as well as stimulating practical activities, a fact that generates a certain degree of satisfaction. Conclusion: Medical students submitted to the PBL method are more likely to be associated with better learning outcomes and medical-scientific performance. However, better study designs, based on rigorous systematic methodologies are required in order to elucidate the benefits and harms of this educational methodology.
