RESUMO

COVID-19, a respiratory illness with a global impact on millions, has recently been linked to manifestations affecting various bodily systems, including the oral cavity. Studies highlight oral issues, like ulcers, blisters, and white patches, alongside olfactory and gustatory dysfunction, influencing an individual's quality of life. In this context, our study aimed to assess the frequency of oral lesions, olfactory and gustatory disorders, and xerostomia resulting from COVID-19. An observational study was conducted with 414 patients to evaluate the frequency of oral symptoms resulting from COVID-19. Patients were diagnosed with mild symptoms and evaluated through clinical examination of the oral cavity and a questionnaire to assess functional alterations. The findings showed that 139 out of 414 patients presented clinical manifestations, with oral lesions being the most prevalent (19.1%), followed by gustatory disorders (18.1%), xerostomia (14.2%), and olfactory dysfunction (14%). The most prevalent oral lesions were ulcerations (n = 51), candidiasis (n = 8), and erythema or red plaques (n = 7). Unfortunately, 50 (12.1%) patients died during this study. Therefore, oral lesions, olfactory and gustatory dysfunctions, and xerostomia are common symptoms associated with COVID-19.

RESUMO

OBJECTIVE: To describe the clinical outcomes and risk factors of death related to mental disorders in a cohort of Brazilian hospitalized patients with COVID-19. METHODS: This retrospective cohort study utilized the Brazilian database SIVEP-Gripe to analyze patients aged ≥18 years who had been hospitalized with COVID-19 between 2020 and 2022. The exposure of interest were mental disorders (anxiety, depression, schizophrenia, and bipolar disorder), identified through self-reported fields. The primary outcome was in-hospital mortality. Covariates included demographic and clinical features. Descriptive statistics, t-tests, chi-square tests, and binary logistic regression were used to analyze the data. RESULTS: A cohort of 2,124,285 patients was included in the analysis, with 23,246 individuals (1.1%) having self-reported mental disorders. Among these mental disorders, depression was the most prevalent (52.3%). The mortality rate of the patients with mental disorders was 30.8%. Analysis of risk factors for mortality revealed that age, gender, region, dyspnea, low oxygen saturation, and comorbidities were associated with an increased risk of death. Patients with schizophrenia had a higher mortality risk (aOR:1.68;95%CI:1.54-1.81). CONCLUSIONS: Patients diagnosed with schizophrenia have a greater likelihood of COVID-19- related death than those without mental health conditions. These findings underscore the significant effect of serious mental disorders on COVID-19 mortality.

RESUMO

BACKGROUND AND OBJECTIVES: We aimed to analyze the study designs, modeling approaches, and performance evaluation metrics in studies using machine learning techniques to develop clinical prediction models for children and adolescents with COVID-19. METHODS: We searched four databases for articles published between 01/01/2020 and 10/25/2023, describing the development of multivariable prediction models using any machine learning technique for predicting several outcomes in children and adolescents who had COVID-19. RESULTS: We included ten articles, six (60 % [95 % confidence interval (CI) 0.31 - 0.83]) were predictive diagnostic models and four (40% [95 % CI 0.170.69]) were prognostic models. All models were developed to predict a binary outcome (n= 10/10, 100 % [95 % CI 0.72-1]). The most frequently predicted outcome was disease detection (n=3/10, 30% [95 % CI 0.11-0.60]). The most commonly used machine learning models in the studies were tree-based (n=12/33, 36.3% [95 % CI 0.17-0.47]) and neural networks (n=9/27, 33.2% [95% CI 0.15-0.44]). CONCLUSION: Our review revealed that attention is required to address problems including small sample sizes, inconsistent reporting practices on data preparation, biases in data sources, lack of reporting metrics such as calibration and discrimination, hyperparameters and other aspects that allow reproducibility by other researchers and might improve the methodology.

RESUMO

BACKGROUND: Oseltamivir is a low-cost antiviral agent that could support or complement treatment of COVID-19. This study assessed whether oseltamivir is effective in reducing COVID-19-related mortality. METHODS: This retrospective cohort study evaluated real-world data from a nationwide database of hospitalisation due to severe acute respiratory syndrome in Brazil. Propensity score matching was used to mimic a randomised controlled trial with 'oseltamivir' and 'no antivirals at all' as the intervention and control groups, respectively. RESULTS: A total of 21 480 and 268 486 patients admitted between February 2020 and January 2023 were included in the intervention and control groups, respectively. After matching, the odds ratio (OR) for death was 0.901 (95% confidence interval [CI] 0.873-0.930). The OR (95% CI) for death in patients who were admitted to the ICU, and on non-invasive or invasive ventilation was 0.868 (0.821-0.917), 0.935 (0.893-0.980), and 0.883 (0.814-0.958), respectively. CONCLUSIONS: Overall, the use of oseltamivir was associated with an attributable risk reduction of 2.50% (95% CI 1.77-3.29). Similar results were observed in patients who were admitted to the ICU, and on non-invasive or invasive ventilation. Oseltamivir is a low-cost potential antiviral treatment for COVID-19.

RESUMO

Abstract Introduction: Brazilian scientific production has shown substantial growth and achieved international visibility. However, in general, the participation of women in scientific activities remains limited. Objective: This study aimed to evaluate the indicators of scientific productivity of women fellows of the Council for Scientific and Technological Development (CNPq) in the field of Medicine. Method: This cross-sectional study was conducted on 541 (211 women, 39%) researchers registered as recipients of CNPq research productivity (PQ) scholarships in Medicine according to a list provided in December 2022. Results: There was a predominance of male researchers (n=330; 61%). In both the male and female groups, most researchers were at level 2, with 62.5% women and 47.2% men (p=0.018). All 211 female PQ scholars were distributed among 37 different institutions and published 34,969 papers in scientific journals, averaging 165.7 articles per researcher. In the last five years of the study period (from 2018 to 2022), 9,679 papers were published. Over their careers, the 211 researchers supervised 5,440 undergraduate research students, 4,144 master's degree students, and 2,923 PhD candidates. There was a significant difference between the scholarship levels for the development of human resources in undergraduate research (p=0.040), master's degree (p=0.027), and PhD. (p<0.001). Conclusion: There are still less women participating in CNPq medical research than men. However, we observed a substantial participation of women in all the assessed items, including technical and scientific production and the human resources training.


Resumo Introdução: A produção científica brasileira apresentou crescimento substancial e visibilidade internacional. Contudo, em geral, a participação das mulheres em atividades científicas ainda é limitada. Objetivo: Este estudo objetivou avaliar os indicadores de produtividade científica de mulheres bolsistas do Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) na área de medicina. Método: Foi realizado estudo transversal com 541 (211 mulheres, 39%) pesquisadores cadastrados como bolsistas de produtividade em medicina do CNPq conforme lista disponibilizada em dezembro de 2022. Resultado: Houve predomínio de pesquisadores do sexo masculino (n = 330; 61%). Em ambos os grupos, masculino e feminino, a maioria dos investigadores encontra-se no nível 2, sendo 62,5% mulheres e 47,2% homens (p = 0,018). Todos os 211 pesquisadores foram distribuídos em 37 instituições diferentes e publicaram 34.969 artigos em revistas científicas, com média de 165,7 artigos por pesquisador. De 2018 a 2022, foram publicados 9.679 artigos. Ao longo de suas carreiras, os 211 pesquisadores orientaram 5.440 alunos de iniciação científica, 4.144 alunos de mestrado e 2.923 alunos de doutorado. Houve diferença significativa entre os níveis de bolsas quanto ao desenvolvimento de recursos humanos em iniciação científica (p = 0,040), mestrado (p = 0,027) e doutorado (p < 0,001). Conclusão: Ainda há menor participação de mulheres do que de homens entre os pesquisadores médicos do CNPq. Contudo, foi possível observar participação substancial das mulheres em todos os quesitos avaliados, incluindo a produção técnica e científica e a formação de recursos humanos.

RESUMO

ABSTRACT Purpose: This study aimed to analyze the diagnostic accuracy of dynamic and static ultrasound (DSUS) in detecting vesicoureteral reflux (VUR) and renal scarring in a cohort of children with neurogenic bladder (NB). Materials and Methods: A retrospective, longitudinal, observational study was conducted using the Reporting Diagnostic Accuracy Studies guideline. The DSUS (index test) data were compared with voiding cystourethrography (VCUG) and renal scintigraphy 99mTc-dimercaptosuccinic (reference tests). Overall performance for predicting VUR and renal scarring was assessed using renal pelvic diameter (RPD)/distal ureteral diameter and renal parenchymal thinning on DSUS, respectively. Results: A total of 107 patients (66 girls, median age 9.6 years) participated. Seventeen patients (15.9%) presented VUR, eight bilateral. For overall reflux grade, the AUC was 0.624 for RPD and 0.630 for distal ureteral diameter. The diagnostic performance for detecting high-grade VUR was slightly better for DSUS parameters. The AUC was 0.666 for RPD and 0.691 for distal ureteral diameter. The cut-offs of 5 mm for RPD and 6.5 mm for distal ureteral diameter presented the best diagnostic odds ratio (DOR) to identify high-grade VUR. The increase of RPD during detrusor contractions showed an accuracy of 89.2%. The thinness of renal parenchyma presented an accuracy of 88% for renal scarring. Conclusion: DSUS predicts VUR and renal scarring in children with NB with fair to good accuracy, and all measurements exhibited a high negative predictive value (NPV). The increase in RPD during voiding or detrusor contractions proved to be the most accurate parameter for indicating the presence of VUR in this study.

RESUMO

This study aims to reevaluate and compare the data from the Brazilian Unified Health System (SUS) on the number of diagnoses of systemic lupus erythematosus (SLE) in the pre-pandemic period with those in the pandemic period, as well as to compare the first year (2020) of the COVID-19 pandemic in Brazil with the last year (2021), to update the data, and to verify whether SLE disease control measures were effective in 2021. There was a consistent and significant increase in the incidence of SLE cases all over Brazil between the first and second pandemic years and between the pre-pandemic triennium and the second pandemic year. Therefore, it is inescapable to have larger clinical studies with different populations to better understand the relationship between these two conditions and find measures to improve the control of this disease.

RESUMO

Introduction: Due to the coronavirus 2019 disease (COVID-19) pandemic, health systems worldwide have suffered interferences, with the interruption of sexual health clinics, limitation of ambulatory consults, prevention, diagnosis, and treatment of several diseases, especially syphilis, altering their epidemiology.Objective: To investigate the impact of the pandemic on syphilis diagnosis in Brazil, the main goal of this study was to update and reevaluate data from the Brazilian Unified Health System on the number of syphilis cases reported in all five Brazilian geographic regions and verify the response of the Brazilian health care to the COVID-19 pandemic. Methods: The data were retrieved from the National Disease Notification System and the Department of Chronic Conditions Diseases and Sexually Transmitted Infections and represent syphilis diagnosis in Brazil, from March to December 2017 to 2019, 2020, and 2021. Results: The increase in the number of syphilis cases was minor compared to 2020, keeping the Southeast region as the most impacted (+146.1%) and an increase of 22,633 cases throughout Brazil (+54.3%). Conclusion:Syphilis disease control measures were ineffective in 2021 as the drop in the number of cases was irrelevant compared to the years before the pandemic. The association between the increase in syphilis cases in Brazil and the COVID-19 pandemic should be further investigated to assist in decision-making processes and in the programming of health actions in addition to finding measures to raise the control of this disease.


Introdução: Em consequência da pandemia de COVID-19, os sistemas de saúde em todo o mundo sofreram interferências, com interrupção de clínicas de saúde sexual, limitação de consultas ambulatoriais, de prevenção, diagnóstico e tratamento de diversas doenças, principalmente a sífilis, alterando sua epidemiologia. Objetivo: Para investigar o impacto da pandemia no diagnóstico da sífilis no Brasil, o objetivo principal do presente estudo foi atualizar e reavaliar os dados do Sistema Único de Saúde sobre o número de casos de sífilis notificados nas cinco regiões geográficas brasileiras e verificar a resposta da atenção básica à saúde brasileira diante da pandemia de COVID-19. Métodos: Os dados foram retirados do Sistema Nacional de Notificação de Agravos e do Departamento de Doenças Crônicas e Infecções Sexualmente Transmissíveis e representam o diagnóstico de sífilis no Brasil, de março a dezembro de 2017 a 2019, 2020 e 2021. Resultados: O aumento no número de casos de sífilis foi menor em relação a 2020, mantendo-se a Região Sudeste como a mais impactada (+146,1%) e havendo aumento de 22.633 casos em todo o Brasil (+54,3%). Conclusão: As medidas de controle da sífilis foram ineficazes em 2021, pois a queda no número de casos foi irrelevante em comparação aos anos anteriores à pandemia. A associação entre o aumento dos casos de sífilis no Brasil e a pandemia de COVID-19 deve ser mais bem investigada para auxiliar nos processos de tomada de decisão e na programação das ações de saúde, além de se encontrarem medidas para elevar o controle desta doença.

RESUMO

BACKGROUND: Human behavior is crucial in health outcomes. Particularly, individual behavior is a determinant of the success of measures to overcome critical conditions, such as a pandemic. In addition to intrinsic public health challenges associated with COVID-19, in many countries, some individuals decided not to get vaccinated, streets were crowded, parties were happening, and businesses struggling to survive were partially open, despite lockdown or stay-at-home instructions. These behaviors contrast with the instructions for potential benefits associated with social distancing, use of masks, and vaccination to manage collective and individual risks. OBJECTIVE: Considering that human behavior is a result of individuals' social and economic conditions, we investigated the social and working characteristics associated with reports of appropriate protective behavior in Brazil. METHODS: We analyzed data from a large web survey of individuals reporting their behavior during the pandemic. We selected 3 common self-care measures: use of protective masks, distancing by at least 1 m when out of the house, and handwashing or use of alcohol, combined with assessment of the social context of respondents. We measured the frequency of the use of these self-protective measures. Using a frequent pattern-mining perspective, we generated association rules from a set of answers to questions that co-occur with at least a given frequency, identifying the pattern of characteristics of the groups divided according to protective behavior reports. RESULTS: The rationale was to identify a pool of working and social characteristics that might have better adhesion to behaviors and self-care measures, showing these are more socially determined than previously thought. We identified common patterns of socioeconomic and working determinants of compliance with protective self-care measures. Data mining showed that social determinants might be important to shape behavior in different stages of the pandemic. CONCLUSIONS: Identification of context determinants might be helpful to identify unexpected facilitators and constraints to fully follow public policies. The context of diseases contributes to psychological and physical health outcomes, and context understanding might change the approach to a disease. Hidden social determinants might change protective behavior, and social determinants of protective behavior related to COVID-19 are related to work and economic conditions. TRIAL REGISTRATION: Not applicable.

RESUMO

BACKGROUND: Congenital Anomalies of the Kidney and the Urinary Tract (CAKUT) are defined as a heterogeneous group of anomalies that resulted from defects in kidney and urinary tract embryogenesis. CAKUT have a complex etiology. Genetic, epigenetic and environmental factors have been investigated in this context. Angiotensin II is a potent vasoconstrictor and exerts an important role in kidney embryogenesis. The angiotensin-converting enzyme (ACE) converts Angiotensin I into Angiotensin II (Ang II) and ACE gene has insertion/deletion (I/D) polymorphisms that have been evaluated in several nephropathies. This study aimed to evaluate whether the I/D polymorphisms of ACE gene and the circulating levels of Ang II are associated with any CAKUT phenotype or CAKUT in general. METHODS AND RESULTS: Our study was performed with 225 pediatric patients diagnosed with CAKUT and 210 age-and-sex matched healthy controls. ACE I/D alleles were analysed by real-time polymerase chain reaction (RT-PCR). The distribution of ACE I/D polymorphisms were compared between CAKUT patients and healthy controls, as well between ureteropelvic junction obstruction (UPJO), vesicoureteral reflux (VUR), multicystic dysplastic kidney (MCDK) phenotypes and control group. No statistical association was detected between ACE I/D polymorphism and CAKUT and UPJO, VUR, and MCDK phenotypes. In a subset of 80 CAKUT patients and 80 controls, plasma levels of Ang II were measured. No significant differences were found between CAKUT patients and controls, even in regard to comparisons of UPJO, VUR and MCDK with control group. CONCLUSION: Although CAKUT is a complex disease and the ACE gene may exert a role in kidney embryogenesis, CAKUT was not associated with any ACE I/D polymorphisms nor with differences in plasma levels of Ang II in this Brazilian pediatric population.

RESUMO

INTRODUCTION: Coronavirus disease 2019 (COVID-19) has limited the access of patients with Hansen's disease (HD) to care due to changes in routine health services. METHODS: To ascertain this, we compared the number of HD cases diagnosed before and after the COVID-19 pandemic. RESULTS: The decrease in HD cases in Brazil reached 18,223 (-48.4%), corresponding to an average reduction of 1,518 cases per month during the COVID-19 pandemic. CONCLUSION: Therefore, effective measures should be implemented to minimize the damage and the consequent negative health impact of COVID-19 on the care of HD patients.

RESUMO

Abstract: Introduction: The aim of this study was to describe the profile and scientific production of research fellows of the Brazilian Council for Scientific and Technological Development (CNPq) in the neuroscience area. Methods: We created a database containing 542 researchers who were CNPq fellows in Medicine, of which 94 (17.34%) worked mainly in the neuroscience area. Results: The researchers were distributed in eight Brazilian States: São Paulo (n=49; 52.12%), Rio Grande do Sul (n=22; 23.40%), Rio de Janeiro (n=9; 9.57%), Minas Gerais (n=5; 5.31%), Ceará (n=4; 4.25%), Santa Catarina (n=3; 3.19%), Espirito Santo (n=1; 1.06) and Paraná (n=1, 1.06%). Although the neuroscience researchers were from more than 20 institutions, 58.5% worked in only 3 of those, namely USP (n=30), UFRGS (n=15) and UNIFESP (n=10). The median time since obtaining the PhD degree was 18.27 years (range, 5-39). Throughout their academic careers, 94 researchers published 16,488 papers in scientific journals, with an average of 175.40 articles per researcher (ranging from 43 to 715 articles). Of the 16,488 articles,12,801 or 77.63% were indexed at Web of Science (mean of 136.18 articles/researcher), while 10,166 or 61.65% were indexed at Scopus database (mean of 108.14 articles/researcher). Overall, those researchers advised 1,279 undergraduate students (median of 13.60; range: 0-68), of which 1,329 were master's degree students (median of 14.13; range: 1-49) and 970 PhD students (median of 10.54; range: 0-42). The fellows' median H-index at ISI was 23.75. Conclusion: It is observed that the neuroscience fellows constitute a group with significant scientific production (the fellows' median H-index at ISI was 23.75). Most of these scientific publications were indexed at the Web of Science (77.63%) and Scopus (61.65%) databases. Human resources training are also highlighted, including undergraduate students, master's degree students and PhD students. Comparative studies with researchers from other countries, in similar areas of knowledge, are necessary to better understand the present results.


Resumo: Introdução: Este estudo avaliou o perfil e a produção científica dos bolsistas do Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) na área de neurociência. Método: Construiu-se um banco de dados com os 542 pesquisadores em medicina cadastrados como bolsistas do CNPq. Desse montante de pesquisadores, 94 (17,34%) tinham a área de neurociência como principal campo de pesquisa. Resultados: Todos os 94 pesquisadores da neurociência estavam distribuídos em oito estados brasileiros: São Paulo (n = 49; 52,12%), Rio Grande do Sul (n = 22; 23,40%), Rio de Janeiro (n = 9; 9,57%), Minas Gerais (n = 5; 5,31%), Ceará (n = 4; 4,25%), Santa Catarina (n = 3; 3,19%), Espírito Santo (n = 1; 1,06) e Paraná (n = 1, 1,06%). Quanto à instituição de origem, os pesquisadores da neurociência distribuíram-se por 20 instituições diferentes no país. No entanto, três instituições foram responsáveis por aproximadamente 58,50% dos pesquisadores: USP (n = 30), UFRGS (n = 15) e Unifesp (n = 10). A mediana do tempo desde a obtenção do título de doutor foi de 18,27 anos (IQ, 5-39). Ao longo da carreira acadêmica, os 94 pesquisadores publicaram 16.488 artigos em periódicos científicos, com uma média de 175,40 artigos por pesquisador (variando de 43 a 715 artigos). Dos 16.488 artigos, 12.801 (77,63%) foram indexados na Web of Science (média de 136,18 artigos/pesquisador) e 10.166 (61,65%) na base Scopus (média de 108,14 artigos/pesquisador). Durante a carreira, os bolsistas orientaram 1.279 estudantes de iniciação científica (mediana de 13,60; intervalo: 0-68), 1.329 estudantes de mestrado (mediana de 14,13; intervalo: 1-49) e 970 de doutorado (mediana de 10,54; intervalo: 0-42). O índice H mediano no ISI dos bolsistas foi de 23,75.
