Graduated compression stockings as a prophylactic measure in venous thromboembolism and edema of lower limbs triggered by air travel: a systematic review of clinical trials.

The increase in duration and frequency of flights has led to an increase in the prevalence of venous thromboembolism among airline passengers. This study assesses the efficacy of graduated compression stockings for prevention of venous thromboembolism triggered by flights lasting more than 3 hours. The design is a systematic review of clinical trials. The methodological quality of studies and the level of scientific evidence were evaluated using the Consolidated Standards of Reporting Trials and Grading of Recommendations Assessment, Development and Evaluation standards. A total of 34 articles were identified, but only eight met the eligibility criteria. The outcomes incidence of venous thromboembolism and edema were assessed in 2,022 and 1,311 passengers, respectively. The studies presented high quality evidence demonstrating prevention of edema and moderate quality evidence of reduced incidence of venous thromboembolism associated with wearing graduated compression stockings during flights.

Early stimulation for neuropsychomotor development in children with microcephaly: a systematic review.

OBJECTIVE: To systematically review studies on the effects of early stimulation on the neuropsychomotor development of children with microcephaly. DATA SOURCE: A systematic review was conducted in PubMed/MEDLINE, Virtual Health Library, and Cochrane Library databases. Studies that addressed the use of early stimulation in playful and interactive environments in children with microcephaly were included. There were no restrictions on the publication date or language of the studies. The outcomes assessed were muscle tone, social interaction, fine and gross motor skills, intelligence quotient, socioemotional and adaptive behavior of the child. The methodological quality and the scientific evidence level were assessed using the Risk of Bias in Non-randomized Studies of Interventions, the Revised Cochrane risk of bias tool for randomized trials and the Grading of Recommendations Assessment, Development and Evaluation. DATA SYNTHESIS: 264 articles were identified, but only 7 met the eligibility criteria. The included studies had a total population of 125 individuals, with sample sizes ranging from 1 to 71 participants. CONCLUSIONS: The studies showed low evidence of an effect of early intervention on the outcomes muscle tone, social interaction, fine and gross motor skills, intelligence quotient, and socioemotional and adaptive behavior in children with microcephaly.

Clinical and epidemiological aspects of victims of maritime accidents on the Mar Grande-Salvador crossing, Bahia, Brazil: a case series study.

BACKGROUND: Maritime transportation is an activity of vital importance for societies. The Mar Grande-Salvador crossing is an intercity waterway transport line in Brazil that transports 3,500 passengers/day, including residents and tourists. In 2017, an accident on this crossing was considered to be the biggest maritime tragedy in Bahia in the last decade. OBJECTIVE: To describe the clinical and epidemiology characteristics of victims of this maritime accident, with analysis on bodily injuries, causes of death and means/instruments that caused the fatal injuries. DESIGN AND SETTING: Case-series study at the Forensic Medical Institute of Bahia, Brazil. METHODS: Reports on 73 victims who were examined for bodily injury or were necropsied by the Forensic Medical Institute were analyzed. This study was approved by the institution's Research Ethics Committee (protocol 04012218.1.0000.5032). RESULTS: The victims' mean age was 33.0 years [95% confidence interval, CI, 26.3-47.0]. The mean age of those who died was 43.0 years [95% CI, 30.5-53.5]. Bodily injuries were found in 74% of the victims. The most frequent bodily injuries were ecchymoses among females (69.7%) and abrasions among males (76.2%). Blunt instruments produced most bodily injuries (85.2%). Among the victims who died, 68.4% were female. Mechanical asphyxiation through drowning was the leading cause of death (89.4%). The overall lethality rate was 26%, and this was higher among females (28.2%). CONCLUSION: Women were the main victims of this maritime accident. Bodily injuries occurred more frequently than death, but these injuries proved to be quite significant, thus demonstrating the importance of measures to improve the safety of navigation.

Association between headache and tinnitus among medical students.

BACKGROUND: Headache is a very common complaint and it is increasingly prevalent among university students. Tinnitus consists of subjectively perceived sounds that occur in the absence of an external auditory signal. Presence of headache and tinnitus in association has implications for therapy and prognosis, because this describes the temporality of the symptoms. Recognition of the epidemiological profile of symptomatic students might contribute to interventions. OBJECTIVE: To investigate the prevalence of the association between headache and tinnitus, and to describe the epidemiological profile of the study population and the chronological order of appearance of these symptoms. METHODS: Cross-sectional, observational and analytical study on a sample representative of an academic center. Data referring to the epidemiological and clinical profile of headache and tinnitus among medical students were collected through an online questionnaire built using the Google Forms tool. RESULTS: Out of the 234 participants, 26.1% reported having tinnitus and headache (p < 0.001). The participants with headache were more likely to be women (p = 0.045), white (p = 0.009) and 21-25 years old (p = 0.356). Among right-sided, left-sided and non-unilateral headaches, tinnitus was present predominantly in the non-unilateral type, but without statistical significance. Regarding timing, 18.0% of the students said that tinnitus started before headache, 57.4% said that headache started before tinnitus and 24.6% said that they started simultaneously. CONCLUSIONS: An important association between headache and tinnitus regarding lateralization and temporality was demonstrated. Thus, these data match the presumption that headache and tinnitus have a physiopathological connection.

Sedentary behavior among medical students: repercussions of the coronavirus pandemic / Conduta sedentária entre estudantes de medicina: repercussões da pandemia do coronavírus

ABSTRACT Introduction: In order to face COVID-19, social restriction measures were adopted that influenced the population's living habits, increasing sedentary lifestyle. Considering the high complexity and dedication required by the Medicine course, it becomes relevant to investigate the effect of the pandemic on the practice of physical exercise and sedentary behavior of these students. Objective: Identify changes in physical activity and sedentary behavior self-reported by medical students in the city of Salvador, Bahia, before and during the self-confinement imposed by the COVID-19 pandemic. Methods: Longitudinal, prospective, quantitative study carried out with regularly enrolled medical students over 18 years of age. A virtual, structured, anonymous, self-completed questionnaire was applied, containing sociodemographic and academic aspects. In addition, the International Physical Activity Questionnaire (IPAQ) was applied in its short version, considering the period before and during the pandemic. Through this, the level of physical activity, sedentary behavior and time spent walking and performing moderate and vigorous activities were measured. Results: 268 medical students were included, predominantly women (65.7%), white (50.0%) and mixed race (38.8%), aged 24.2 ± 5.5 years, single (90.7%), attending the clinical cycle (59.0%), in private institutions (78.4%). No statistically significant differences were identified in the level of physical activity and in the time spent with moderate and vigorous activities. However, there was a reduction in walking time (p<0.00001) and an increase in sedentary behavior (p=0.001) during the COVID-19 pandemic, with the greatest impact among women (p=0.0009). Conclusion: The repercussions of the COVID-19 pandemic have been shown to increase the sedentary behavior of medical students, especially among women, and to reduce activity time spent with walking. Longitudinal studies are needed to analyze the medium and long-term consequences of this change in the healthy lifestyle habits of medical students. Level of evidence II; Comparative prospective study.

RESUMO Objetivo: Analisar se houve impacto da pandemia de COVID-19 na prevalência de transtornos mentais comuns (TMCs) entre estudantes de Medicina, investigando os possíveis fatores de risco associados. Métodos: Estudo observacional, desenvolvido com 289 estudantes de Medicina de Salvador, Bahia, realizado antes e durante a pandemia da COVID-19. Utilizou-se um questionário estruturado contendo dados sociodemográficos, acadêmicos e sobre hábitos de vida. O rastreamento de TMC foi realizado por meio do Self-Report Questionnaire (SRQ-20). A coleta de dados ocorreu em duas etapas: a primeira, presencial (período anterior à pandemia) e a segunda, virtual (período pandêmico). Resultados: Não houve diferença na prevalência de TMC entre os momentos antes e durante a pandemia (48,0% vs. 44,5%, p = 0,577). Durante a pandemia, verificou-se aumento do envolvimento religioso (80,6% vs. 92,7%, p = 0,002) e do consumo de bebidas alcoólicas (45,9% vs. 69,1%, p < 0,001). Entre os estudantes, observou-se aumento de TMC entre homens (17,0% vs. 34,1%, p = 0,036); redução entre mulheres (83,0% vs. 65,9%, p = 0,036); aumento entre aqueles com envolvimento religioso (80,9% vs. 92,9%, p = 0,036); e aumento em todos os ciclos acadêmicos (p = 0,039). Conclusão: Apesar de a prevalência de TMC em estudantes de Medicina manter-se expressiva, não foi demonstrado impacto direto da pandemia de COVID-19 em suas taxas. Ademais, a prevalência de TMC foi maior entre os estudantes com engajamento religioso e consumidores de bebida alcoólica.

ABSTRACT Objective: To analyze whether there was an impact of the COVID-19 pandemic on the prevalence of common mental disorders (CMD) among medical students, investigating the possible associated risk factors. Methods: It is an observational study, developed with 289 medical students from Salvador, Bahia, carried out before and during the COVID-19 pandemic. A structured questionnaire containing sociodemographic, academic and lifestyle data was used. CMD screening was performed using the Self-Report Questionnaire (SRQ-20). Data collection took place in two stages: the first in person (period before the pandemic) and the second virtual (pandemic period). Results: There was no difference in the prevalence of CMD between the moments before and during the pandemic (48.0% vs. 44.5%, p = 0.577). During the pandemic, there was an increase in religious involvement (80.6% vs. 92.7%, p = 0.002) and consumption of alcoholic beverages (45.9% vs. 69.1%, p < 0.001). Among students, there was an increase in CMD among men (17.0% vs. 34.1%, p = 0.036); reduction among women (83.0% vs. 65.9%, p = 0.036); increase among those with religious involvement (80.9% vs. 92.9%, p = 0.036); and increase in all academic cycles (p = 0.039). Conclusion: Although the prevalence of CMD in medical students remains expressive, there was no direct impact of the COVID-19 pandemic on its rates. In addition, the prevalence of CMD was higher among students with religious commitment and alcohol drinkers.

Introdução: A permanência prolongada na Unidade de Terapia Intensiva (UTI) compromete a funcionalidade e a qualidade de vida dos pacientes. Programas de exercícios podem contribuir na melhora do status funcional e aceleração do retorno às atividades. Objetivo: avaliar a segurança de exercícios em pacientes na UTI, descrevendo as condições hemodinâmicas e respiratórias e a ocorrência de efeitos adversos. Métodos: trata-se de um estudo não controlado, do tipo "antes e depois", realizado com 42 pacientes internados em UTI, submetidos à mobilização através de cinesioterapia passiva, cinesioterapia ativa, sedestração e deambulação. Além dos dados epidemiológicos e clínicos, foram avaliados os efeitos adversos da mobilização. As variáveis hemodinâmicas e respiratórias foram mensuradas à beira do leito, em três momentos: antes, durante e imediatamente após a mobilização. Resultados:Foram estudados pacientes idosos (65,8±13,7 anos), predominantemente mulheres (59,5%), com diagnóstico admissional de natureza clínica (64,3%). Os pacientes em ventilação mecânica realizaram predominantemente cinesioterapia passiva (57,1%) e aqueles em ventilação espontânea realizaram predominantemente sedestração (28,6%) e deambulação (28,6%). Dentre os efeitos adversos, observou-se padrão muscular ventilatório insatisfatório (7,1%), saturação periférica de oxigênio inferior a 90% (4,8%), alteração da pressão arterial (7,1%). Não houve registro de alteração da frequência cardíaca, extubação acidental ou perda de acesso venoso durante as mobilizações, assim como não foram observadas alterações no comportamento hemodinâmico, respiratório e da oxigenação antes, durante e após a mobilização. Conclusão: exercícios físicos demonstraram-se seguros, viáveis em qualquer âmbito clínico, respeitando-se os limites de segurança, podendo trazer benefícios potenciais para pacientes internados em UT (AU).

Introduction: The prolonged stay in the Intensive Care Unit (ICU) compromises the functionality and quality of life of patients. Physical exercise can contribute to improving functional status and accelerating return to activities. Objective: to assess the safety of patient mobilization in the ICU, describing the hemodynamic and respiratory conditions and the occurrence of adverse effects. Methods: This is an uncontrolled, "before and after" study, carried out with 42 patients hospitalized in the ICU, submitted to mobilization through passive kinesiotherapy, active kinesiotherapy, seating and walking. In addition to epidemiological and clinical data, the adverse effects of mobilization were evaluated. Hemodynamic and respiratory variables were measured at the bedside, at three times: before, during and immediately after mobilization. Results: Elderly patients (65.8±13.7 years), predominantly women (59.5%), with a clinical admission diagnosis (64.3%) were studied. Patients on mechanical ventilation predominantly performed passive kinesiotherapy (57.1%) and those on spontaneous ventilation predominantly performed seating (28.6%) and walking (28.6%). Among the adverse effects, there was an unsatisfactory ventilatory muscle pattern (7.1%), peripheral oxygen saturation less than 90% (4.8%), and changes in blood pressure (7.1%). There was no record of changes in heart rate, accidental extubation or loss of venous access during mobilizations, as well as changes in hemodynamic, respiratory and oxygenation behavior before, during and after mobilization were not observed. Conclusion: physical exercises proved to be safe, viable in any clinical environment, respecting safety limits, and may bring potential benefits to patients admitted to the ICU (AU).

Formação para enfrentar a morte na perspectiva de futuros médicos / Training to cope with death from the perspective of future physicians / Formación para afrontar la muerte en la perspectiva de los futuros médicos

Resumo Ocasionalmente, a morte é considerada falha ou insucesso da medicina e a inabilidade em enfrentá-la pode gerar medo e frustração, interferindo nas decisões clínicas. Este estudo avaliou a percepção de estudantes de medicina quanto ao enfrentamento da morte, analisando seu preparo para lidar com essas situações e comparando seus perfis sociodemográfico, religioso e acadêmico. Realizou-se estudo transversal, quantitativo e qualitativo, com 294 estudantes de medicina da Bahia. Demonstrou-se que o estudante de medicina considera a morte um processo natural, mas não se sente totalmente preparado para lidar com a terminalidade da vida durante a prática clínica, possivelmente em razão das escassas discussões acadêmicas e da oferta insuficiente de conteúdo teórico-prático durante a formação. Homens com formação prévia e que tiveram contato pessoal e acadêmico com a morte foram associados à maior percepção de preparo para lidar com a terminalidade da vida, sem interferência de ciclo acadêmico e religião.

Abstract Occasionally, death is considered a medical failure and the inability to cope with it can generate fear and frustration, interfering with clinical decisions. This study assessed how medical students perceived coping with death, analyzing their preparedness to tackle these situations and comparing their sociodemographic, religious and academic profiles. This cross-sectional, quantitative and qualitative study was conducted with 294 medical students from Bahia. Results showed that medical students consider death to be a natural process, but do not feel fully prepared to address end of life during clinical practice, possibly due to the scarcity of academic discussions and the insufficient theoretical and practical content during training. Men with previous training and who had personal and academic contact with death were associated with a greater perceived preparedness to cope with death, without interference from academic level and religion.

Resumen En ocasiones, se percibe la muerte como un fracaso de la medicina, y la incapacidad de afrontarla puede generar miedo y frustración, interfiriendo en las decisiones clínicas. Este estudio evaluó la percepción de los estudiantes de medicina sobre el enfrentamiento a la muerte, analizando su preparación para lidiar con esta situación y comparando sus perfiles sociodemográficos, religiosos y académicos. En este estudio transversal, cuantitativo y cualitativo participaron 294 estudiantes de medicina de Bahía (Brasil). Los estudiantes de medicina perciben la muerte como algo natural, pero no se sienten totalmente preparados para afrontar el final de la vida durante la práctica clínica, posiblemente debido a escasas discusiones académicas y a insuficientes contenidos en la formación teórico-práctica. Los hombres con formación previa y que tuvieron contacto personal y académico con la muerte tuvieron una mayor percepción de preparación para afrontar el final de la vida, sin interferencia académica y de la religión.

Quality of Life in Patients After Acute ST-Segment Elevation Myocardial Infarction

Abstract Background: ST-segment elevation myocardial infarction (STEMI) is the acute coronary syndrome with the highest severity and mortality. It can affect physical health and well-being of patients, and consequently their quality of life (QoL). Objective: To describe the QoL of patients at 30 days and 180 days after STEMI, focusing on sex differences and repercussions on physical and mental dimensions. Methods: Observational study with 174 STEMI patients included in the study on STEMI conducted in the city of Salvador, Brazil (PERSISST). The QoL of patients at 30 days (D30) and 180 days (D180) after the coronary event was assessed using the 12-item short form health survey (SF-12). Physical and mental components of QoL were calculated using the SF-12 OrthoToolKit. Descriptive analysis of data was made using the IBM SPSS software, version 25.0. Results: Mean age of participants at D30 and D180 was 57.1±11.4 years and 60.5±10.9 years, respectively, with a higher prevalence of men (55.8% and 56.8%). In general, patients had a poor QoL at both time points (scores 49.1±8.9 and 49.9±8.4, respectively). Analysis by sex, however, showed that men had a good QoL at both 30D (score 51.8±7.4) and 180 D (score 51.3±7.7), whereas a poor QoL was found among women at these time points (45.7±9.6 and 48.1±9.0, respectively). Men showed higher physical and mental health scale scores than women at both D30 and D180, and there was a greater impairment of the physical component in both sexes. Conclusion: Patients had poor QoL at 30 days and 180 days after STEMI, with a greater impairment of the physical component and a worse QoL perception among women than men at both time points.

Aplicou-se, por meio do Microsoft Forms, um questionário virtual, estruturado e anônimo contendo 21 perguntas acerca do perfil acadêmico e das atividades extracurriculares realizadas, além de dados sobre a produção científica e as motivações e dificuldades enfrentadas pelos estudantes. Resultado: Dos 460 estudantes participantes, houve predominância de mulheres (63,3%), com idade de 24,1+6,1 anos, cursando os ciclos básico (45,4%) e clínico (46,7%), que não possuem desejo prévio de trabalhar com pesquisa (54,8%). Dentre os participantes, 54,6% integraram ligas acadêmicas, 31,1% possuem envolvimento com grupos de pesquisa e 29,1% participaram de monitoria. Verificou-se que apenas 33,9% dos estudantes possuem resumos publicados em congressos, 12,2% são coautores de artigos científicos e 7,4% são autores principais. O interesse em trabalhar com pesquisa aumenta durante a graduação (p = 0,010), estando os estudantes motivados para produzir cientificamente (66,1%). A experiência em pesquisa (27,4%) e o interesse genuíno na descoberta científica (20,9%) foram os principais fatores motivadores. Entretanto, 81,1% dos discentes identificaram dificuldades para produzir conteúdo científico e apontaram como empecilhos a orientação inadequada (16,0%) e a falta de tempo (15,5%). Não foi observada relação entre a motivação e a dificuldade para produzir cientificamente e o ciclo acadêmico em curso. Conclusão: Os estudantes de Medicina demonstram interesse e participação em pesquisa científica, entretanto aqueles que, de fato, estão envolvidos com atividades científicas representam a minoria.

Abstract: Introduction: Knowledge and understanding of scientific research are skills that must be developed by all health professionals. Specifically in Medicine, these skills make up an important part of undergraduate and continuing medical education. Considering that medical training is closely related to the understanding of scientific evidence, it becomes relevant to analyze the involvement of medical students with scientific activities during the course. Objective: This study aimed to investigate the interest and involvement in scientific research among medical students, analyzing the academic profile and the extracurricular activities carried out, in addition to evaluating the scientific production and identifying the motivations and difficulties faced. Method: A cross-sectional study carried out with medical students from Salvador/Bahia, over 18 years of age. A virtual, structured, anonymous questionnaire was applied through Microsoft Forms, containing 21 questions about the academic profile and extracurricular activities carried out, in addition to data on scientific production and the motivations and difficulties faced by students. Result: Of the 460 participating students, there was a predominance of women (63.3%), aged 24.1+6.1 years, attending the basic (45.4%) and clinical (46.7%) cycles, who have no previous desire to work with research (54.8%). Among the participants, 54.6% were part of academic leagues, 31.1% were involved in research groups and 29.1% participated in monitoring. It was found that only 33.9% of students have abstracts published in congresses, 12.2% are co-authors of scientific articles and 7.4% are main authors. Interest in working with research increases during graduation (p = 0.010), with students motivated to produce scientifically (66.1%). Research experience (27.4%) and genuine interest in scientific discovery (20.9%) were the main motivating factors. However, 81.1% of students identify difficulties in producing scientific content, with inadequate guidance (16.0%) and lack of time (15.5%) being the main obstacles. No relationship was observed between motivation and difficulty to produce scientifically and the current academic cycle. Conclusion: Medical students show interest and participation in scientific research, however those who are actually involved in scientific activities represent the minority.

Prevalence and psychological repercussion of phantom breast syndrome in women undergoing mastectomy: a systematic review

Breast cancer is the most common cancer among women in the world and the leading cause of death among Brazilian women. The presence of phantom breast syndrome (PBS) is one of the possible postoperative complications and may reach prevalences of up to 53% among mastectomized women. This study assessed the scientific evidence regarding the presence of PBS and its psychological repercussions in women undergoing mastectomy. This is a systematic review of observational studies based on the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses methodology. The methodological quality of the studies and the level of scientific evidence were assessed using the Newcastle-Ottawa Scale and the Grading of Recommendations Assessment, Development and Evaluation. A total of 95 articles were identified, but only 11 met the eligibility criteria. The outcomes of the presence of PBS and psychological repercussion were evaluated in 2,160 and 1,996 patients, respectively. It was found that the prevalence of PBS varies according to age, being on average 28% and reaching up to 50% in women under 80 years of age. This phenomenon can occur from three months to six years after amputation, tending to regress over time. Anxiety, depression, and sleep disorders are the most prevalent psychological effects (35.8%, 31.5%, and 29.2%, respectively). The studies presented strong scientific evidence of PBS and moderate evidence of psychological repercussions associated with this context.

Clinical and epidemiological aspects of victims of maritime accidents on the Mar Grande-Salvador crossing, Bahia, Brazil: a case series study

ABSTRACT BACKGROUND: Maritime transportation is an activity of vital importance for societies. The Mar Grande-Salvador crossing is an intercity waterway transport line in Brazil that transports 3,500 passengers/day, including residents and tourists. In 2017, an accident on this crossing was considered to be the biggest maritime tragedy in Bahia in the last decade. OBJECTIVE: To describe the clinical and epidemiology characteristics of victims of this maritime accident, with analysis on bodily injuries, causes of death and means/instruments that caused the fatal injuries. DESIGN AND SETTING: Case-series study at the Forensic Medical Institute of Bahia, Brazil. METHODS: Reports on 73 victims who were examined for bodily injury or were necropsied by the Forensic Medical Institute were analyzed. This study was approved by the institution's Research Ethics Committee (protocol 04012218.1.0000.5032). RESULTS: The victims' mean age was 33.0 years [95% confidence interval, CI, 26.3-47.0]. The mean age of those who died was 43.0 years [95% CI, 30.5-53.5]. Bodily injuries were found in 74% of the victims. The most frequent bodily injuries were ecchymoses among females (69.7%) and abrasions among males (76.2%). Blunt instruments produced most bodily injuries (85.2%). Among the victims who died, 68.4% were female. Mechanical asphyxiation through drowning was the leading cause of death (89.4%). The overall lethality rate was 26%, and this was higher among females (28.2%). CONCLUSION: Women were the main victims of this maritime accident. Bodily injuries occurred more frequently than death, but these injuries proved to be quite significant, thus demonstrating the importance of measures to improve the safety of navigation.

Mortality from Cardiovascular Diseases: A Comparative Analysis between the Medical and Non-Medical Populations in Brazil

Abstract Background: Cardiovascular disease (CVD) is the leading cause of death worldwide, including among physicians. Professional peculiarities increase cardiovascular risk in this population, making it relevant to analyze mortality in the medical population (MPop) and non-medical population (NMPop). Objectives: To compare the CVD mortality coefficient (MC) in between MPop and NMPop in Brazil by analyzing the epidemiological profile and the main causes of deaths from CVD. Methods: Time-series study with data obtained from the Mortality Information System of the Federal Council of Medicine and the Brazilian Institute of Geography and Statistics, from 2014 to 2018. The variables age group, sex, race, occupation, and CVD that caused the death were assessed in MPop and NMPop. MC, relative risk and odds ratio between the populations were calculated. Tests for difference in proportions, with approximation to the normal distribution, and chi-squared tests were performed, assuming p<0.01 as statistically significant. Results: Both MPop and NMPop had a predominance of men (86.7% and 52.3%), senior citizens (85.9% and 79.7%) and white individuals (86.4% and 52.2%). The MCs of the MPop and NMPop was 92.2 and 255.1 deaths/100,000 individuals, respectively. The main cause of death was acute myocardial infarction (AMI) (32.5% and 24.6% in MPop and NMPop, respectively) followed by cerebrovascular accident (CVA) (5.1% and 10.5% in MPop and NMPop, respectively). Conclusion: In Brazil, mortality from CVD was more prevalent in white elderly males, and mainly caused by AMI and CVA. Being a doctor, man and over 60 years old represents a greater chance of death from CVD in comparison with non-physicians.

Prevalence of common mental disorders among medical students during the Covid-19 pandemic / Prevalência de transtornos mentais comuns entre estudantes de Medicina durante a pandemia de Covid-19

Abstract: Introduction: Common mental disorders (CMD) have been frequently identified among university students in the health area, especially in Medicine. It is believed that characteristics inherent to the course have a potential influence on the student's mental health. When adding the pandemic context, with its inherent social restrictions, the psychological determinants related to the unknown pathology and the fear of the rapid spread of the new coronavirus, there is the possibility of increasing the risk factors for psychological distress in this population. Objective: To estimate the prevalence of CMD among medical students during the COVID-19 pandemic, analyzing its main determinants in the academic, social and economic spheres. Method: Cross-sectional study, carried out with 388 medical students in Salvador/BA., Data on sociodemographic and academic aspects, life habits, comorbidities and symptoms of non-psychotic disorders were collected using the Google Forms platform, measured by the Self-Reporting Questionnaire (SRQ-20). Results: The prevalence of CMD was 39.7% among medical students, with 47.4% in the basic cycle, 40.3% in the clinical cycle and 12.3% in the internship period. Among the factors associated with the emergence of CMD are sedentary lifestyle, smoking, use of substances that enhance academic performance, dissatisfaction with one's academic performance, poor sleep quality, lack of appetite, frequent headaches, poor digestion, suicidal ideation and sadness. There was a higher rate of non-psychotic mental disorders among women, with no difference regarding the academic cycle and the administrative type of the educational institution. Conclusion: During the COVID-19 pandemic, a significant prevalence of CMD was demonstrated among female, white, single medical students who live with family members and do not have their own income. Although studies suggest an increase in the prevalence among university students at the present time, the data from the present study remain in agreement with the literature data prior to the pandemic, showing that the medical course itself is the main risk factor for higher rates of CMD in this population. However, further studies on the long-term impact of the pandemic on the mental health of university students are still necessary.

Resumo: Introdução: Transtornos mentais comuns (TMC) têm sido frequentemente identificados entre universitários na área de saúde, especialmente em Medicina. Acredita-se que características inerentes ao curso exerçam potencial influência na saúde mental do estudante. Quando se adiciona o contexto de pandemia com as restrições sociais inerentes, os determinantes psicológicos relacionados à desconhecida patologia e o temor do rápido alastramento do novo coronavírus, existe a possibilidade de potencialização dos fatores de riscos para o sofrimento psíquico nessa população. Objetivo: Este estudo teve como objetivo estimar a prevalência de TMC entre estudantes de Medicina durante a pandemia da Covid-19, analisando seus principais determinantes nos âmbitos acadêmico, social e econômico. Método: Trata-se de estudo transversal, realizado com 388 estudantes de Medicina em Salvador, na Bahia. Por meio da plataforma Google Forms, coletaram-se dados sociodemográficos e acadêmicos, sobre hábitos de vida, comorbidades e sintomas de transtornos não psicóticos mensurados pelo Self-Reporting Questionnaire (SRQ-20). Resultado: A prevalência de TMC foi de 39,7% entre os estudantes de Medicina, sendo de 47,4% no ciclo básico, 40,3% no ciclo clínico e 12,3% no internato. Entre os fatores associados ao surgimento de TMC, estão sedentarismo, tabagismo, uso de substâncias que favoreçam o desempenho acadêmico, insatisfação com o próprio rendimento acadêmico, má qualidade de sono, falta de apetite, cefaleia frequente, má digestão, ideação suicida e tristeza. Observou-se maior índice de transtornos mentais não psicóticos entre as mulheres, não havendo diferença quanto ao ciclo acadêmico e à natureza administrativa da instituição de ensino. Conclusão: Durante a pandemia de Covid-19, demonstrou-se uma expressiva prevalência de TMC entre estudantes de Medicina do sexo feminino, brancos, solteiros, que residem com familiares e não possuem renda própria. Apesar de estudos sugerirem aumento da prevalência nos universitários no momento atual, os dados deste estudo permaneceram concordantes com a literatura anterior à pandemia, configurando o próprio curso de Medicina como principal fator de risco para taxas superiores de TMC nessa população. Entretanto, novos estudos acerca do impacto em longo prazo da pandemia na saúde mental dos universitários ainda são necessários.

Objetivo: avaliar a eficácia da simulação realística (SR) na graduação em medicina com base no conhecimento adquirido e na melhoria do desempenho clínico e analisar a percepção dos estudantes quanto à aplicabilidade do método como ferramenta de ensino. Métodos: foi realizada uma revisão sistemática de artigos científicos nas bases de dados PubMed, Lilacs e SciELO, em inglês e português, publicados no período de 2015 a 2020, utilizando a seguinte estratégia de busca: (simulation training OR simulation patient) AND (students medical AND education, medical, undergraduate). Resultados: dos 261 artigos identificados, apenas sete atenderam aos critérios de inclusão e exclusão estabelecidos, 57,2% deles com baixo ou moderado nível de evidência. Todos demonstraram que a SR promove modificações positivas no processo de construção acadêmica dos estudantes, contribuindo para o desenvolvimento de habilidades e competências essenciais para a formação médica. Além disso, houve majoritária percepção positiva dos estudantes quanto à utilização da SR como método de ensino durante a formação médica. Conclusão: houve evidências de eficácia da SR na aprendizagem e favorável percepção dos estudantes de medicina quanto à sua utilização. Todavia, os desafios relativos à sua implantação e execução, bem como o restrito número de artigos de alto rigor metodológico, limitam a inferência inequívoca de sua eficácia na educação médica.

Aims: to evaluate the effectiveness of realistic simulation (RS) in medical graduation based on the knowledge acquired and on the improvement of clinical performance, and to analyze the students' perception regarding the applicability of the method as a teaching tool. Methods: a systematic review of scientific articles was carried out in the PubMed, Lilacs and SciELO databases, in English and Portuguese, published from 2015 to 2020, using the following search strategy: (simulation training OR simulation patient) AND (students medical AND education, medical, undergraduate). Results: of 261 identified, only seven met the inclusion and exclusion criteria (57.2% with a low or moderate level of scientific quality). All of them demonstrated that RS promotes positive changes in the students' academic construction process, contributing to the development of essential skills and competences for medical education. In addition, there was a majority positive perception of students regarding the use of RS as a teaching method during medical training. Conclusion: there was evidence of the effectiveness of RS in learning and favorable perception of medical students regarding its use. However, the challenges related to its implementation and execution, as well as the limited number of articles of high methodological rigor, limit the unequivocal inference of its effectiveness in medical education.
