Physician's perceptions regarding the pharmaceutical industry: a Brazilian national study.

OBJECTIVE: The objective of this study was to investigate the newly graduated physicians' attitudes and perceptions regarding the medical relationship with the pharmaceutical industry and identify the sociodemographic patterns related to such thinking. METHODS: A structured questionnaire was administered to 4,601 participants selected from a pool of 16,323 physicians who were registered with one of the 27 Regional Medical Councils of Brazil in 2015. Answers were analyzed using two stratification variables: type of medical school (public vs. private) and the sex of the respondents. RESULTS: Out of the participants, 61.8% believed that industry funding could support medical conferences and education, and 48.4% felt that small gifts and conference travel funding were acceptable. Conversely, 64.7% disagreed with industry-sponsored social events. Views on whether pharmaceutical representatives' visits influenced prescriptions were divided. Statistically significant differences were observed between genders and medical school types, with men and private school graduates being more accepting of certain industry interactions. CONCLUSION: The study highlights the nuanced attitudes of new doctors toward industry relationships, indicating the need for clearer ethical guidelines and education in medical schools to align practice with evolving societal values.

Brazilian Physicians Mental Health: A Cross-Sectional Nationwide Study exploring factors associated with prevalence of suicide planning and attempts.

OBJECTIVES: To report suicide planning and attempts' in a lifetime among Brazilian physicians and to explore associated risk factors. METHODS: A nation-wide, online survey based on the Tool for the Assessment of Suicide Risk and Satisfaction with Life Scale was conducted among Brazilian physicians (January 2018 - January 2019). Multivariate explored associations of demographics, psychological, and work-related factors on suicide planning and attempts reports. RESULTS: Among 4,148 respondents, 1,946 (53.5%) were male, 2,527 (60.9%) were 30-60 years old, 2,675 (64.5%) had 2-4 work-contracts and 1,725 (41.6%) reported a weekly workload of 40-60 hours. Overall prevalence of suicide plans was 8.8% (n=364) and suicide attempts were reported by 3.2% (n=133) of respondents. Daily (AdjOR=7.857;95%CI 2.282-27.051, p=0.002) or weekly emotional exhaustion (AdjOR=7.953; 95%CI 2.403-26.324, p=0.001), daily frustration with work (AdjOR=3.093;95%CI 1.711-5.588, p<0.001), and being bisexual (AdjOR=5.083;95%CI 2.544-10.158, p<0.001) were significantly associated with higher odds of reports. Among extremely dissatisfied professionals 38.3% reported having made suicide planning and attempts, while among extremely satisfied only 2.8% reported it (p<0.001). CONCLUSIONS: Brazilian physicians with a lifetime history of suicide planning and attempts presented a higher association with emotional exhaustion and frustration with work. Urgent actions are needed to promote professional protection policies and resilience.

Mental health of Brazilian physicians: a nationwide cross-sectional study to investigate factors associated with the prevalence of suicide plans and attempts

Objective: To report on suicide plans and attempts among Brazilian physicians and to investigate the associated risk factors. Methods: From January 2018 to January 2019, a nationwide online survey was conducted among Brazilian physicians using the Tool for Assessment of Suicide Risk and the Satisfaction with Life Scale. Multivariate exploratory associations of demographic, psychological, and work-related factors were performed on reports of suicide plans and attempts. Results: Of the 4,148 participants, 1,946 (53.5%) were male, 2,527 (60.9%) were 30 to 60 years old, 2,675 (64.5%) had two to four jobs, and 1,725 (41.6%) worked 40 to 60 hours a week. The overall prevalence of suicide plans was 8.8% (n=364), and suicide attempts were reported by 3.2% (n=133) of participants. Daily emotional exhaustion (ORadj = 7.857; 95%CI 2.282-27.051, p = 0.002), weekly emotional exhaustion (ORadj = 7.953; 95%CI 2.403-26.324, p = 0.001), daily frustration at work (ORadj = 3.093; 95%CI 1.711-5.588, p < 0.001), and bisexuality (ORadj = 5.083; 95%CI 2.544-10.158, p < 0.001) were significantly associated with higher odds of suicide. Extremely dissatisfied physicians reported suicide plans and attempts in 38.3% of cases, whereas extremely satisfied physicians reported suicide plans and attempts in only 2.8% of cases (p < 0.001). Conclusion: Brazilian physicians with a history of suicide plans and attempts express emotional exhaustion and frustration at work. There is an urgent need for actions to promote professional safeguards and resilience.

Mortalidade em domicílio durante pandemia de covid-19 / Home mortality during the COVID-19 pandemic / Muerte en el hogar durante la pandemia de COVID-19

Resumo O estudo investigou a mortalidade em domicílio durante a pandemia de SARS-CoV-2 em Santa Catarina, utilizando dados secundários do Serviço de Atendimento Móvel de Urgência caracterizando óbitos notificados pelas equipes. A análise dos dados, acessados no Portal da Transparência do governo estadual, revelou aumento nos óbitos atendidos pelas equipes de urgência na região. Destacou-se também incremento médio de 2,16/100 mil habitantes na taxa de mortalidade por doenças cardiovasculares inespecíficas entre 2019 e 2022, diferenciando Santa Catarina do restante do Brasil. Essa disparidade pode estar associada à falta de controle dos fatores de risco e comorbidades durante a pandemia. Os achados ressaltam a necessidade de medidas preventivas para mitigar os efeitos adversos sobre a mortalidade domiciliar e melhorar os serviços de saúde, especialmente em relação à equidade na distribuição de recursos escassos durante a pandemia.

Abstract The study investigated home mortality during the SARS-CoV-2 pandemic in Santa Catarina, using secondary data from the Mobile Emergency Care Service characterizing deaths reported by the teams. Analysis of the data, accessed via the state government's Transparency Portal, uncovered a rise in deaths attended to by emergency teams in the area. It also highlighted an average increase of 2.16 per 100,000 residents in the mortality rate attributable to non-specific cardiovascular diseases between 2019 and 2022, distinguishing Santa Catarina from the rest of Brazil. This contrast could be linked to inadequate management of risk factors and comorbidities during the pandemic. The findings underscore the need for preventive measures to alleviate adverse impacts on home mortality and enhance healthcare services, particularly concerning equity in the allocation of limited resources amid the pandemic.

Resumen El estudio investigó la muerte en el hogar durante la pandemia por SARS-CoV-2 en el estado de Santa Catarina, en Brasil, utilizando datos secundarios del Servicio de Atención Móvil de Urgencia que caracterizan las defunciones notificadas por los equipos. El análisis de los datos, a los que se tuvo acceso por medio del Portal de la Transparencia del gobierno estatal, puso de manifiesto un aumento en las muertes atendidas por los equipos de urgencia en la región. También se resaltó un incremento medio de 2,16/100.000 habitantes en la tasa de mortalidad por enfermedades cardiovasculares inespecíficas entre el 2019 y el 2022, lo que diferencia a Santa Catarina del resto de Brasil. Esta disparidad puede estar asociada a la falta de control de los factores de riesgo y comorbilidades durante la pandemia. Los hallazgos resaltan la necesidad de adoptar medidas preventivas para mitigar los efectos adversos sobre la muerte en el hogar y mejorar los servicios de salud, en especial con respecto a la equidad en la distribución de recursos escasos durante la pandemia.

Perception of newly graduated physicians toward ethical education in medical schools: a Brazilian cross-sectional nationwide study.

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.

There is no shortage, but inequality: demographic evolution of neurologists in Brazil (2010-2020).

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.

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.

Preoperative inflammatory markers as prognostic predictors after hepatocellular carcinoma resection: data from a western referral center.

BACKGROUND: Recent studies from eastern centers have demonstrate an association between inflammatory response and long-term outcomes after hepatocellular carcinoma (HCC) resection. However, the prognostic impact of inflammatory markers in western patients, with distinct tumor and epidemiologic features, is still unknown. AIM: To evaluate the prognostic impact of preoperative neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and monocyte-to-lymphocyte ratio (MLR), as well as their impact according to tumor size (< 5 cm, 5-10 cm, > 10 cm) in patients undergoing HCC resection with curative intent. METHODS: Optimal cut-off values for NLR, PLR, and MLR were determined by plotting the receiver operator curves. Overall survival (OS) and disease-free survival (DFS) curves were calculated using the Kaplan-Meier method and compared using the log-rank test. The Cox method was used to identify independent predictors of OS and DFS. RESULTS: In total, 161 consecutive adult patients were included. A high NLR (> 1.715) was associated with worse OS (P = 0.018). High NLR (> 2.475; P = 0.047) and PLR (> 100.25; P = 0.028) were predictors of short DFS. In HCC < 5 cm, MLR (> 1.715) was associated with worse OS (P = 0.047). In the multivariate analysis, high PLR was an independent predictor of worse DFS [hazard ratio (HR) 3.029; 95%CI 1.499-6.121; P = 0.002]. CONCLUSION: Inflammatory markers are useful tools to predict long-term outcomes after liver resection in western patients, high NLR was able to stratify subgroups of patients with short OS and DFS, an increased PLR was an independent predictor of short DFS, while high MLR was associated with short OS in patients with early HCC.

Cultural adaptation and updating of the Risk assessment and management of exposure of health care workers in the context of covid-19 questionnaire.

OBJECTIVE: to translate and culturally adapt the Risk assessment and management of exposure of health care workers in the context of covid-19 questionnaire to the Brazilian context and to develop and evaluate a sociodemographic and occupational characterization questionnaire to compose the adapted questionnaire. METHOD: five stages were conducted to adapt the Risk assessment and management of exposure of health care workers in the context of covid-19 questionnaire, namely: translation, synthesis of the translations, evaluation by a committee of judges, back translation and pre-test. As for the complementary questionnaire, it was elaborated and evaluated by a committee of judges and a pre-test was carried out. RESULTS: the questionnaires were validated and the pre-test stage was conducted with health workers and students. CONCLUSION: the final version adapted to the Brazilian context was called Questionário de avaliação de risco e gestão da exposição de trabalhadores e estudantes de saúde no contexto da covid-19 and is available for use, together with the final version of the Sociodemographic and occupational questionnaire: Risk assessment and management of exposure of health care workers and students in the context of covid-19. These questionnaires may assist in mitigating the risks of infection, illness and death of health workers and students due to covid-19.

Attitude and knowledge of medical students toward donation after circulatory death.

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.

C-peptide level as predictor of type 2 diabetes remission and body composition changes in non-diabetic and diabetic patients after Roux-en-Y gastric bypass.

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.

How many and which physicians? A comparative study of the evolution of the supply of physicians and specialist training in Brazil and Spain.

BACKGROUND: In the face of the medical workforce shortage, several countries have promoted the opening of medical schools and the expansion of undergraduate and specialization education in medicine. Few studies have compared the characteristics and effects of expanding the supply of general practitioners and specialist physicians between countries. Brazil and Spain, two countries with distinct historical processes and socioeconomic scenarios, yet both with universal public health systems and common aspects in training and medical work, have registered a significant increase in the number of physicians and can be used to understand the challenges of strategic planning for the medical workforce. METHODS: This study provides a descriptive approach using longitudinal data from official databases in Brazil and Spain from 1998 to 2017. Among the comparable indicators, the absolute numbers of physicians, the population size, and the physician's ratio by inhabitants were used. The number of medical schools and undergraduate places in public and private institutions, the supply of residency training posts, and the number of medical specialists and medical residents per 100 000 inhabitants were also used to compare both countries. Seventeen medical specialties with the highest number of specialists and comparability between the two countries were selected for further comparison. RESULTS: Due to the opening of medical schools, the density of physicians per 1 000 inhabitants grew by 28% in Spain and 51% in Brazil between 1998 and 2017. In that period, Spain and Brazil increased the supply of annual undergraduate places by 60% and 137%, respectively. There is a predominance of private institutions providing available undergraduate places, and the supply of medical residency posts is smaller than the contingent of medical graduates/general practitioners each year. CONCLUSION: Both countries have similar specialist densities in cardiology, dermatology, and neurosurgery specialties. However, family medicine and community in Spain has 91.27 specialists per 100 000 inhabitants, while in Brazil, the density is only 2.64. The comparative study indicated the complexity of the countries' decisions on increasing the medical supply of general practitioners and specialist physicians. Research and planning policies on the medical workforce must be aligned with the actual health needs of populations and health systems.

Hepatitis B viremia in HIV-coinfected individuals under antiretroviral therapy

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.
