Abstract Background Neurology is a medical specialty that deals with prevalent diseases such as stroke, headache, epilepsy, and neurodegenerative diseases. Many countries, such as Brazil, struggle to provide neurological care for their populations, but the inadequacy and unequal distribution of the neurologist workforce are real challenges. Objective To analyze the demographic evolution of neurologists and the first-year Neurology residency positions in Brazil during the last decade (2010–2020) and the distribution imbalance between regions. Methods The demographic and geographic distribution of neurologists was calculated based on data extracted from the Brazilian Federal Medical Council reports, and the number of Neurology residency positions was based on the Brazilian National Commission of Medical Residency reports. Indicators of wealth were associated with demographic data. Results The number of neurologists per 100,000 population has increased since 2011, with a similar increase in the geographic distribution of neurologists. However, there was a marked inequality of distribution of neurologists through regions, with a gap between the Northern (lowest) and Southeastern (highest) regions. Furthermore, the imbalance of distribution of neurologists strongly correlated with social inequality. The number of Neurology residency positions increased, but with an imbalance between North and Southeast regions. Conclusions Brazil has advanced in providing neurologists. However, instead of a shortage, inequality between regions is the greatest challenge regarding the neurological workforce. The training of new neurologists is unequal between regions and occurs at a slower rate than needed. Neurologists, public health authorities, and patients should discuss solutions for these issues.

Resumo Antecedentes A Neurologia é uma especialidade médica que lida com doenças prevalentes, como acidente vascular cerebral, cefaleia, epilepsia e doenças neurodegenerativas. Muitos países, como o Brasil, se esforçam para oferecer assistência neurológica à população, mas a distribuição insuficiente e desigual da força de trabalho de neurologistas são desafios. Objetivo Analisar a evolução demográfica dos médicos neurologistas e das vagas de Programas de Residência Médica em Neurologia no Brasil durante a última década (2010-2020) e o desequilíbrio de distribuição entre as regiões. Métodos A distribuição demográfica e geográfica de neurologistas foi calculada com base nos dados extraídos de relatórios do Conselho Federal do Medicina do Brasil, e o número de vagas em Programas de Residência Médica em Neurologia foi extraído de dados da Comissão Nacional de Residência Médica. Os indicadores de riqueza foram associados aos dados demográficos. Resultados O número de neurologistas por 100.000 habitantes aumentou desde 2011, com um aumento similar na distribuição geográfica de neurologistas. Entretanto, houve uma nítida desigualdade na distribuição de neurologistas entre as regiões, com um hiato entre as regiões Norte e a Sudeste. Além disso, a desigualdade da distribuição de neurologistas se correlacionou fortemente com a desigualdade social. O número de vagas em Programas de Residência Médica aumentou, porém com desigualdade entre as regiões Norte e Sudeste. Conclusões O Brasil tem avançado na geração de neurologistas. Porém, ao invés de uma escassez, a desigualdade entre regiões é o maior desafio em relação à força de trabalho neurológica. O treino de novos neurologistas é desigual entre regiões e ocorre em um ritmo mais lento do que o necessário. Neurologistas, autoridades em saúde pública e pacientes devem discutir soluções para estes problemas.

SUMMARY OBJECTIVE: The objective of this study was to evaluate fresh medical graduates’ perceptions regarding the general aspects of ethics teaching in Brazilian medical schools. METHODS: A structured questionnaire was applied to 4,601 participants among the 16,323 physicians who registered in one of the 27 Regional Medical Councils of Brazil in 2015. Answers to four questions regarding general aspects of ethics education in medical school were analyzed. Sampling procedures involved two stratification variables: legal nature (public vs. private) of medical schools and monthly household income higher than 10 minimum wages. RESULTS: A large percentage of the participants had witnessed unethical behaviors during contact with patients (62.0%), toward coworkers (51.5%), and in relationships with patients’ families (34.4%) over the course of their medical training. Even though most of the responders (72.0%) totally agreed that patient-physician relationship and humanities education were part of their medical school curriculum, important topics such as conflicts of interest and end-of-life education were not satisfactorily addressed in the participants’ medical training. Statistically significant differences were found between the answers of public and private school graduates. CONCLUSION: Despite great efforts to improve medical ethics education, our findings suggest the persistence of deficits and inadequacies in the ethics training currently given in medical schools in Brazil. Further modifications in ethics training must be made to address the deficiencies shown in this study. This process should be accompanied by continuous evaluation.

Objective: to identify the evidence related to the risks of SARS-CoV-2 exposure in healthcare workers and the interventions adopted. Method: systematic literature review in eight scientific databases and three gray literature repositories. Results: 26 studies identified as risk factors: scarcity, inadequate use or reuse of personal equipment; low adherence to precautionary measures; working in intensive care and COVID-19 sectors; long stay in a closed work environment; sharing eating areas without the use of masks and distance; low knowledge and unpreparedness for disease management. 12 studies identified as interventions: health surveillance programs with early detection, diagnosis and early withdrawal; organization of care flows; double triage; telemedicine; limitation of visits; creation of exclusive sectors for care to COVID-19; qualification and training with virtual tools and simulation. Conclusion: besides the risk of infection, individual, psychosocial and organizational factors made the healthcare work environment unsafe. Interventions should be adopted to mitigate the risks and decrease the professionals' morbidity and mortality.

Objetivo: identificar as evidências relacionadas aos riscos de exposição ao SARS-CoV-2 em profissionais de saúde e as intervenções adotadas. Método: revisão sistemática de literatura em oito bases de dados científicas e três repositórios de literatura cinzenta. Resultados: 26 estudos identificaram como fator de risco: escassez, uso inadequado ou reuso de equipamentos individuais; baixa adesão às medidas de precaução; atuação em terapia intensiva e setores COVID-19; longa permanência em ambiente de trabalho fechado; compartilhamento de espaços para alimentação sem uso de máscara e distanciamento; baixo conhecimento e despreparo para atendimento à doença. 12 estudos identificaram como intervenções:  programas de vigilância em saúde com detecção precoce, diagnóstico e afastamento precoce; organização de fluxos de atendimento; triagem dupla; telemedicina; limitação de visitas; criação de setores exclusivos para atendimento à COVID-19; capacitações e treinamentos com ferramentas virtuais e simulação. Conclusão: além do risco de infecção, fatores individuais, psicossociais e organizacionais tornaram o ambiente de trabalho em saúde inseguro. Intervenções devem ser adotadas para mitigar os riscos e diminuir a morbimortalidade dos profissionais.

SUMMARY OBJECTIVE: A survey among medical students in a Brazilian public university was performed to investigate the acceptance of organ donation in Brazil, particularly donation after circulatory death (DCD). METHODS: A questionnaire including 26 objectives and Likert scale questions was validated and sent to all medical students of our institution. The answers were analyzed considering the whole set of individuals as well as by dividing the medical students into two groups: less graduated students and more graduated students. RESULTS: From 1050 students, 103 spontaneous answers (9.8%) were retrieved after 3 weeks. A total of 89.3% agreed totally with deceased donor organ donation and 8.7% agreed partially. However, only 50.5% of the students agreed totally and 31.1% agreed partially to living donation. Students revealed that 82.6% know the concept of brain death. On the other hand, 71.8% of them declared not knowing the concept of planned withdrawal of life-sustaining therapy, mainly cardiorespiratory support. A total of 85.4% of students agreed totally with donation after brain death and 11.7% agreed partially. However, when questioned about donation in awaiting circulatory death after a planned withdrawal of life-sustaining therapy, only 18.4% agreed totally and 32% agreed partially. Both groups of less and more graduated students showed similar results. CONCLUSIONS: Our study found a clear lack of information and consequently in acceptance of DCD. Education in the field of end-of-life management may improve not only the acceptance of DCD donation but also the whole understanding of planned withdrawal of life-sustaining therapy.

OBJECTIVES: Several predictors of type 2 diabetes mellitus (T2DM) remission after metabolic surgery have been proposed and used to develop predictive scores. These scores may not be reproducible in diverse geographic regions with different baseline characteristics. This study aimed to identify predictive factors associated with T2DM remission after Roux-en-Y gastric bypass (RYGB) in patients with severe obesity. We hypothesized that the body composition alterations induced by bariatric surgery could also contribute to diabetes remission. METHODS: We retrospectively evaluated 100 patients with severe obesity and T2DM who underwent RYGB between 2014 and 2016 for preoperative factors (age, diabetes duration, insulin use, HbA1c, C-peptide plasma level, and basal insulinemia) to identify predictors of T2DM remission (glycemia<126 mg/dL and/or HbA1c<6.5%) at 3 years postoperatively. The potential preoperative predictors were prospectively applied to 20 other patients with obesity and T2DM who underwent RYGB for validation. In addition, 81 patients with severe obesity (33 with T2DM) underwent body composition evaluations by bioelectrical impedance analysis (InBody 770®) 1 year after RYGB for comparison of body composition changes between patients with and those without T2DM. RESULTS: The retrospective analysis identified only a C-peptide level >3 ng/dL as a positive predictor of 3-year postoperative diabetes remission, which was validated in the prospective phase. There was a significant difference in the postoperative body composition changes between non-diabetic and diabetic patients only in trunk mass. CONCLUSION: Preoperative C-peptide levels can be useful for predicting T2DM remission after RYGB. Trunk mass is the most important difference in postoperative body composition changes between non-diabetic and diabetic patients.

ABSTRACT Background: Antiretroviral therapy (ART) has decreased AIDS incidence and mortality, rendering comorbidities, such as hepatitis B more relevant for people living with human immunodeficiency virus (HIV). Since antiretroviral drugs may also inhibit hepatitis B virus (HBV) replication, analyzing the impact of ART on management of hepatitis B in this population is important. Objective: To assess HBV viremia among HIV/HBV coinfected individuals on ART and its associated factors. Method: For this cross-sectional study, HIV/HBV-coinfected individuals, aged over 18 years, who were on ART for over six months and receiving care at an outpatient clinic in São Paulo were recruited. Sociodemographic characteristics, information about viral exposure, clinical and laboratory data, including evaluation of liver fibrosis were obtained. Plasma HBV DNA was measured by polymerase chain reaction. Viral genome sequencing was conducted for genotyping and identification of drug resistance-conferring mutations if viral load exceeded 900 IU/mL. Results: Out of 2,946 patients who attended the clinic in 2015, 83 were eligible and 56 evaluated. Plasma HBV DNA was detected in 16 (28.6%) (95% CI: 18.0-41.3%), all on lamivudine and tenofovir treatment. HBV DNA detection was associated with lower education (p = 0.015), higher international normalized ratios (p = 0.045), history of an AIDS-defining illness [OR: 3.43 (95% CI: 1.10-11.50)], and HBeAg detection [OR: 6.60 (95% CI: 1.84-23.6)]. In contrast, a last CD4+ count above 500 cells/mm3 in the year prior to inclusion [OR: 0.18 (95% CI: 0.04-0.71)] and detection of anti-HBe [OR: 0.21 (95% CI: 0.04-0.99)] were negatively associated. Patients with HBV DNA above 900 IU/mL were infected with subgenotypes A1 (n = 3) and D2 (n = 1), and exhibited viral mutations associated with total resistance to lamivudine and partial resistance to entecavir. Conclusions: Despite being on ART, a significant proportion of HIV/HBV-coinfected individuals present HBV viremia. Characterization of factors that are associated with this finding may help professionals provide better management to these patients.

OBJECTIVE: To evaluate the impact of a complex-care-based medical school in the context of the Brazilian health care system on students’ career choices. METHODS: This was a retrospective cross-sectional study based on medical regulatory organization records. It included records for 7,419 physicians who graduated from FMUSP. Geographic data were analyzed using Kernel maps, and the statistical analysis was performed with SPSS® version 24.0. A p-value less than 0.05 was considered significant. RESULTS: Of the 7,419 physicians, 68.6% (95% CI 67.5-69.7) were male, and 20.7% (95% CI 19.8%-21.7%) had no medical specialty, compared to 46.4% nationwide. Internal medicine and surgery-based specialties were more popular, accounting for 39.4% (95% CI 38.3%-40.5%) and 16.8% (95% CI 15.5%-17.6%) of our study group, compared to the Brazilian averages of 25.9% and 13.5%. Our graduates also had a higher probability of staying in São Paulo City, especially when born outside the city. CONCLUSION: We believe that FMUSP remains an interesting model for studying the impact of a highly specialized center on the education and career choices of medical students.

Abstract Background The infectious diseases specialist is a medical doctor dedicated to the management of infectious diseases in their individual and collective dimensions. Objectives The aim of this paper was to evaluate the current profile and distribution of infectious diseases specialists in Brazil. Methods This is a cross-sectional study using secondary data obtained from institutions that register medical specialists in Brazil. Variables of interest included gender, age, type of medical school (public or private) the specialist graduated from, time since finishing residency training in infectious diseases, and the interval between M.D. graduation and residency completion. Maps are used to study the geographical distribution of infectious diseases specialists. Results A total of 3229 infectious diseases specialist registries were counted, with 94.3% (3045) of individual counts (heads) represented by primary registries. The mean age was 43.3 years (SD 10.5), and a higher proportion of females was observed (57%; 95% CI 55.3–58.8). Most Brazilian infectious diseases specialists (58.5%) practice in the Southeastern region. However, when distribution rates were calculated, several states exhibited high concentration of infectious diseases specialists, when compared to the national rate (16.06). Interestingly, among specialists working in the Northeastern region, those trained locally had completed their residency programs more recently (8.7 yrs; 95% CI 7.9–9.5) than physicians trained elsewhere in the country (13.6 yrs: 95% CI 11.8–15.5). Conclusion Our study shows that Brazilian infectious diseases specialists are predominantly young and female doctors. Most have concluded a medical residency training program. The absolute majority practice in the Southeastern region. However, some states from the Northern, Northeastern and Southeastern regions exhibit specialist rates above the national average. In these areas, nonetheless, there is a strong concentration of infectious diseases specialists in state capitals and in metropolitan areas.

Objetivando traçar a evolução histórica da distribuição de médicos no Brasil segundo sexo, foi realizado estudo epidemiológico do tipo ecológico, por meio do cruzamento de bancos de dados secundários (linkage). Para a caracterização geral dos médicos foram consideradas as bases de dados dos 27 conselhos regionais de medicina, complementadas pelas bases de dados da Comissão Nacional de Residência Médica e da Associação Médica Brasileira. Os resultados mostram que, desde 2009, entre os novos médicos registrados há mais mulheres que homens. Na população de médicos em atividade os homens ainda predominam (60,1%), mas no grupo com 29 anos ou menos as mulheres já são maioria. A tendência consistente de maior participação das mulheres na profissão médica no Brasil, observada ao longo das últimas décadas e acentuada nos últimos anos, indica a necessidade de reavaliar e readequar as propostas para implementação de políticas públicas na área.

Aiming to settle the historical evolution of physicians' distribution in Brazil by gender, an ecological study was conducted by secondary database cross-checking (linkage). For a general characterization of the physicians were considered the 27 Regional Medicine Council, complemented by the National Medical Residency and the Brazilian Medical Association databases. The results show that since 2009, among new registered doctors there are more women than men. Although men still prevail (60.1%) in the active physicians population, in the group aged less than 29 years old, women have become majority. The consistent trend of increased participation of women in the medical profession in Brazil, observed over the past decades and intensified over the past few years, indicates the need to reassess and readjust the proposals for implementation of public policies in the area.

Con el fin de trazar la evolución histórica de la distribución de los médicos en Brasil por sexo, se llevó a cabo un estudio epidemiológico del tipo ecológico, a través de la intersección de las bases de datos secundarias (linkage). Para la caracterización general de los médicos, se han considerado las bases de datos de los 27 Consejos Regionales de Medicina, complementados con las bases de datos de la Comisión Nacional de Residencia Médica y de la Asociación Médica Brasileña. Los resultados muestran que entre los nuevos médicos colegiados hay más mujeres que hombres desde 2009. En la población de los médicos en actividad todavía predominan los hombres (60,1%), pero en el grupo con 29 años o menos, las mujeres son la mayoría. La tendencia constante de aumento de la participación de las mujeres en la profesión médica en Brasil, observada durante las últimas décadas y notablemente en los últimos años, indica la necesidad de reevaluar y reajustar las propuestas para la implementación de políticas públicas en el área.

INTRODUÇÃO: A concentração de cães e gatos em áreas urbanas, associada a um número cada vez mais crescente da população errante desses animais, tem um papel epidemiológico importante na contaminação de solos de praças e parques públicos e na disseminação de infecções por variados gêneros de parasitas. O objetivo do presente estudo foi determinar a frequência de geo-helmintos com potencial zoonótico em solo de praças públicas e escolas municipais infantis da Cidade de Fernandópolis, Estado de São Paulo, Brasil, no período compreendido entre março de 2007 e fevereiro de 2008. MÉTODOS: Foram avaliadas todas as praças (32) e escolas (13) da cidade. As amostras foram testadas pelos métodos de Rugai adaptado, Willis e Caldwell e Caldwell. RESULTADOS: Foram avaliadas 225 amostras de solo com 30,2% (68) de positividade. Nas amostras provenientes de praças públicas, a positividade foi de 40% (64), ao passo que, nas escolas, foi de apenas 6,1% (6). Os ovos de parasitas encontrados foram Toxocara spp. 79,3% (47), Trichuris spp. 13,8% (8) e ancilostomídeos 6,9% (4). Variáveis relacionadas ao local, como o número de cães (OR 21,18 - IC95%: 10,81-41,51), de espécimes de fezes (OR 6,87 - IC95%: 3,51-13,47) e a utilização de cerca (OR 0,1 - IC95%: 0,05-0,20) tiveram impacto na contaminação do solo. CONCLUSÕES: Foram observados, nas amostras contaminadas, parasitas com potencial zoonótico, entre os quais estão os agentes etiológicos de doenças como a larva migrans visceral e cutânea, fato que representa risco a saúde da população que frequenta tais ambientes.

INTRODUCTION: The concentration of dogs and cats in urban areas, associated with an ever-increasing wandering population of these animals, has an important epidemiological role in the soil contamination of public spaces and the spread of infections of several types of parasites. This study aimed to determine the frequency of soil-transmitted helminths with zoonotic potential in public squares and municipal primary schools in Fernandópolis, State of São Paulo, Brazil, conducted between 2007 and 2008. METHODS: All the squares (32) and schools (13) in the town were evaluated. Soil samples were tested using the Rugai method modified by Willis, Caldwell and Caldwell. RESULTS: A total of 225 soil samples were evaluated and 30.2% (68) were positive for helminths. In samples from public squares, 40% (64) contamination was observed; however, contamination in schools was only 6.1% (6). The parasites eggs identified were Toxocara spp. 79.3% (47), Trichuris spp. 13.8% (8) and Ancylostomatidae 6.9% (4). Variables related to the site, such as the number of dogs (OR 21.18, 10.81 - 41.51), fecal samples (OR 6.87, 3.51 - 13.47) and the use of fences (OR 0.1, 0.05 - 0.20), had an impact on soil contamination. CONCLUSIONS: In the contaminated samples, parasites with zoonotic potential were identified, including the etiologic agents of diseases like cutaneous and visceral larva migrans, a fact that poses a risk to health of the population that frequent such environments.
