RESUMO
BACKGROUND: Healthcare systems are currently ill-equipped to diagnose arboviruses rapidly and efficiently or to differentiate between various viruses. METHODS: Utilizing molecular techniques, this study examined arbovirus infections in 459 patients from a public health unit in Goiânia-Goiás, Brazil, a region where arbovirus infection poses a significant public health challenge. RESULTS: Nearly 60% of the analyzed samples tested positive for at least one arbovirus, and over 10% of the patients were co-infected with more than one virus. CONCLUSIONS: Fast and accurate diagnostic tools are essential for informing public health policy and enhancing epidemiological surveillance.

Dengue necessitates accurate diagnosis. Rapid tests such as Bioline™ DENGUE DUO have gained traction, but validation in specific populations is essential. This study aimed to evaluate the performance of the Bioline™ test, alongside assessing the socio-epidemiological profile of symptomatic patients in a Brasília Military Hospital. The serum of 404 symptomatic patients was analyzed by the Bioline™ DENGUE DUO test, followed by Dengue virus detection and discrimination of the four serotypes by RT-qPCR. Accuracy was assessed using parameters including sensitivity (S), specificity (E), positive and negative predictive values (PPV and NPV), and positive (RV +) and negative (RV-) likelihood ratios. The NS1 component exhibited a sensitivity of 70.37%, a specificity of 97.30%, and an overall efficiency of 90.10% when compared to RT-qPCR as the gold standard. The IgM component demonstrated a sensitivity of 26.85%, a specificity of 89.53%, and an overall efficiency of 72.77% when compared to RT-qPCR as the gold standard. The IgG component demonstrated a sensitivity of 23.15%, a specificity of 68.92%, and an overall efficiency of 56.68% when compared to RT-qPCR as the gold standard. Several rapid tests are commercially available. However, considering variations across regions and demographic groups, it is important to question their accuracy in specific populations. Rapid tests are important screening tools, but they can have limitations for the certainty of diagnosis. Bioline™ DENGUE DUO displayed good specificity, but sensitivity was slightly below optimal levels. While helpful for confirming dengue, improvements are needed to effectively rule out the disease.

BACKGROUND: Arboviral diseases are a group of infectious diseases caused by viruses transmitted by arthropods, mainly mosquitoes. These diseases, such as those caused by the dengue (DENV), Zika (ZIKV), chikungunya (CHIKV), and yellow fever (YFV) viruses, have a significant impact worldwide. In this context, entomological surveillance plays a crucial role in the control and prevention of arboviruses by providing essential information on the presence, distribution, and activity of vector mosquitoes. Based on entomological surveillance, transovarian transmission provides information regarding the maintenance and dissemination of arboviruses. The objective of this study was to detect these arboviruses in Goiânia, Goiás, and analyze the occurrence of transovarian transmission. METHODS: Aedes aegypti eggs were collected from different regions of Goiânia and cultivated under controlled laboratory conditions until the emergence of adult mosquitoes. Adult females were grouped into pools containing their heads and thoraxes. These pools were subsequently evaluated using reverse-transcription quantitative polymerase chain reaction (RT-qPCR) assay. RESULTS: A total of 157 pools (N=1570) were analyzed, with two pools testing positive for CHIKV and one pool testing positive for ZIKV, indicating that the offspring resulting from transovarian transmission are potentially infectious. CONCLUSIONS: In summary, the demonstration of the vertical transmission mechanisms of CHIKV and ZIKV in A. aegypti serves as an alert to health authorities, as these diseases are still underreported, and their primary urban vector has likely acquired this capacity, contributing to the dissemination of these infections.

RESUMO
BACKGROUND: Arboviruses are a group of viruses transmitted to vertebrate hosts by certain blood-feeding arthropods. Among urban vectors of arboviruses, mosquitoes of the genus Aedes are the most common. However, other mosquitoes may be susceptible to infection and involved in the transmission, such as Mansonia spp. Therefore, this study aimed to investigate whether Mansonia humeralis can be infected with the Mayaro virus (MAYV). METHODS: These insects were collected from 2018 to 2020 in chicken coops of rural communities in Jaci Paraná in Porto Velho, Rondônia, Brazil, while performing blood-feeding on roosters. The mosquitoes were randomly grouped in pools from which the head and thorax were macerated and checked for the presence of MAYV by quantitative reverse transcription polymerase chain reaction (RT-qPCR). The positive pools were used to infect the C6/36 cell line, and on different days post-infection, the supernatant of the infected cells was subjected to viral detection by RT-qPCR. RESULTS: A total of 183 pools of female mosquitoes were tested, of which 18% were positive for MAYV; some samples from insect pools inoculated into C6/36 cells showed in vitro multiplication capacity between 3 and 7 days post-infection. CONCLUSIONS: This is the first report of Ma. humeralis mosquitoes that are naturally infected by MAYV, indicating that these vectors may be potential transmitting agents of this arbovirus.

Abstract Background: Chromoblastomycosis is a skin infection caused by dematiaceous fungi that take the form of muriform cells in the tissue. It mainly manifests as verrucous plaques on the lower limbs of rural workers in tropical countries. Objectives: The primary objective of this review is to evaluate the accuracy of diagnostic methods for the identification of chromoblastomycosis, considering the histopathological examination as the reference test. Methods: MEDLINE, LILACS and Scielo databases were consulted using the terms ‟chromoblastomycosis" AND ‟diagnosis". The eligibility criteria were: studies that evaluated the accuracy of tests for the diagnosis of chromoblastomycosis. Eleven studies were selected. Statistical analysis included the calculation of sensitivity and specificity of the diagnostic methods. Results: Considering the histopathological examination as the reference test, the culture showed a sensitivity (S) of 37.5% - 90.9% and a specificity (Sp) of 100%; while direct mycological examination showed S = 50% - 91.6% and Sp of 100% . Considering the culture as the reference test, the serology (precipitation techniques) showed S of 36% - 99%; and Sp of 80% - 100%; while the intradermal test showed S of 83.3% - 100% and Sp of 99.4% - 100%. Study limitations: The small number of studies and very discrepant sensitivity results among them do not allow the calculation of summary measures through a meta-analysis. Conclusions: Direct mycological examination, culture, intradermal test and serology show sensitivity and specificity values for the diagnosis of chromoblastomycosis with no significant difference between the studies.

Chromoblastomycosis is a skin infection caused by dematiaceous fungi, characterized by a verrucous plaque on the limbs. It mainly affects rural workers in tropical countries. The purpose of this review is to identify how the diagnostic methods used in the propaedeutic of chromoblastomycosis emerged and were developed. The MeSH terms "chromoblastomycosis" or "chromomycosis" or "verrucous dermatitis" and "diagnosis" were used to search articles indexed in MEDLINE and LILACS databases. The description of a first-time-used method in diagnosing chromoblastomycosis or modifications and innovations in an existing technique was the criteria used to deem the article eligible. The first methods described in diagnosing chromoblastomycosis were histopathological examination and culture, which characterizes and defines the disease in the early 20th century. Subsequently, they were described as direct microscopic examination, fine needle aspiration for cytology, electron microscopy, serology, molecular tests, scintigraphy, nuclear magnetic resonance and dermoscopy. Tests based on the direct identification of the fungus through biopsy, culture, or direct microscopy are the oldest and more employed methods for diagnosing chromoblastomycosis. The polymerase chain reaction was introduced in the last few decades and is a promising technique. Dermoscopy of chromoblastomycosis shows blackish red dots and white and pink areas along with scaling. Other techniques, such as serology and skin testing for delayed-type hypersensitivity, have not been incorporated into clinical practice

Mayaro virus (MAYV) has historically been associated with sylvatic transmission; however, urban outbreaks have been reported in Brazil, including cases of co-detection with dengue virus (DENV). Therefore, we performed a molecular survey to investigate MAYV circulation and cocirculation with DENV within Goiania, a major city in Central-West Brazil. Among 375 subjects with arbovirus-like symptoms, 259 were positive for DENV and 26 for MAYV. Of these, 17 were coinfected with DENV-2, suggesting co-transmission of the viruses. The most common complaints at the time of inclusion were myalgia, headache, fever, arthralgia, retro-orbital pain, and skin rash. No specific symptoms were associated with MAYV when either detected alone or co-detected with DENV, compared to that when DENV was detected alone. Most MAYV-infected subjects were women with no recent travel history to rural/sylvatic areas. Phylogenetic reconstruction indicated that the MAYV identified in this study is closely related with a lineage observed in Peru, belonging to genotype D. Our results corroborate the growing circulation of MAYV in urban environments in Brazil and reinforce the need to implement laboratory diagnosis in the Unified Health System, considering that the clinical manifestations of Mayaro fever are similar to those of other arboviruses, particularly dengue. Furthermore, most cases occurred in association with DENV-2. Further phylogenetic studies are needed to evaluate MAYV, which has not been widely examined.

OBJECTIVE: assess patient responses and associated factors of items on a safe surgery checklist, and identify use before and after protocol implementation from the records. METHODS: a cohort study conducted from 2014 to 2016 with 397 individuals in stage I and 257 in stage II, 12 months after implementation, totaling 654 patients. Data were obtained in structured interviews. In parallel, 450 checklist assessments were performed in medical records from public health institutions in the Southwest II Health Region of Goiás state, Brazil. RESULTS: six items from the checklist were evaluated and all of these exhibited differences (p < 0.000). Of the medical records analyzed, 69.9% contained the checklist in stage I and 96.5% in stage II, with better data completeness. In stage II, after training, the checklist was associated with surgery (OR; 1.38; IC95%: 1.25-1.51; p < 0.000), medium-sized hospital (OR; 1.11; CI95%; 1.0-1.17; p < 0.001), male gender (OR; 1.07; CI95%; 1.0-1.14; p < 0.010), type of surgery (OR; 1.7; CI95%: 1.07-1.14; p < 0.014) and antibiotic prophylaxis 30 to 60 min after incision (OR; 1.10; CI95%: 1.04-1.17; p < 0.000) and 30 to 60 min after surgery (OR; 1.23; CI95%: 1.04-1.45; p = 0.015). CONCLUSIONS: the implementation strategy of the safe surgery checklist in small and medium-sized healthcare institutions was relevant and associated with better responses based on patient, data availability and completeness of the data.

Resumo: Introdução: Neste artigo, fazemos um relato de experiência da implantação e do funcionamento de um programa de mentoria aplicado a estudantes de graduação do curso de Medicina de uma universidade do Centro-Oeste brasileiro. É consenso que a pressão dos cursos de Medicina provoca sobrecarga emocional e afeta negativamente os estudantes, e é preciso que medidas de apoio sejam implementadas. Relato de experiência: O programa de mentoria da Faculdade de Medicina da Universidade Federal de Goiás teve um processo de construção lógico. Foi criado no início de 2015, pelo reconhecimento da necessidade da instituição em apoiar os acadêmicos durante sua graduação, fato evidenciado a partir do atendimento psicológico ao aluno e de uma pesquisa in loco. Os seguintes aspectos-chave caracterizam o programa: é oferecido como uma disciplina eletiva, pode ser feito até cinco vezes e,além de um encontro mensal com o mentor, o estudante escolhe as oficinas de que deseja participar, diversificando assim sua formação. Após 12 semestres de funcionamento, sintetizamos neste artigo uma parte de nossos resultados e algumas reflexões sobre o que queremos para o futuro do programa. Discussão: A implementação da mentoria e suas adequações foram resultados de pesquisa, capacitação, discussões dos docentes e avaliação periódica pelos mentorados. As mudanças procuraram atender às expectativas e sugestões dos estudantes, objetivando atrair a atenção e satisfazer aos anseios dos discentes. Ao longo dos 12 semestres de funcionamento do programa, o interesse dos alunos pela matrícula na disciplina cresceu, com forte avaliação positiva, especialmente pela livre escolha e diversidade de oficinas, e pelo envolvimento do tutor. Conclusão: As instituições de ensino devem estimular a criação de programas de mentoria. O programa relatado neste artigo tem tido boa aceitação por parte dos alunos e nos aponta bons resultados.
Abstract: Introduction: This article reports on the experience of implementing and running a mentoring program for medical school students at a Brazilian university in the Midwest region. It is widely accepted that the pressure at medical school is detrimental to the students and often leads to emotional overload. Therefore, supporting mechanisms must be implemented. Experience report: The mentoring program at the Federal University of Goiás had a logical beginning. It was created in early 2015, after psychotherapy services offered to the students led to an in loco research study, which in turn pointed out the need to provide support to students throughout their undergraduate studies. There are some key characteristic aspects of the program: it's an elective course, which can be taken up to 5 times, and the students can choose the workshops they want to attend in addition to the monthly meeting with the mentor, which allows for diverse paths to be followed. After twelve semesters in existence, this article presents a summary of some of the results obtained and reflections on the future of this program. Discussion: The implementation of the program and its adaptations resulted from research, professional development, discussions among professors and regular assessments by the mentees. Changes were made according to the expectations and suggestions of participating students, aiming to effectively meet their needs and represent a desirable course. Since its inception, the program has attracted increasingly more students, and enjoyed a strong positive evaluation, mainly due to the various workshops to choose from and engagement with the mentor. Conclusion: Universities should support the creation of such mentoring programs. The program discussed in this article has been well received and points towards positive outcomes.

Introduction Simulation in neurosurgery is a growing trend in medical residency programs around the world due to the concerns there are about patient safety and the advancement of surgical technology. Simulation training can improve motor skills in a safe environment before the actual setting is initiated in the operating room. The aim of this review is to identify articles that describe Brazilian simulators, their validation status and the level of evidence (LoE). Methodology This study was conducted using the Preferred Reported Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. A search was performed in the Medline, Scielo, and Cochrane Library databases. The studies were evaluated according to the Medical Education Research Quality Instrument (MERSQI), and the LoE of the study was established according to the classification system of the Oxford Centre for Evidence-Based Medicine (OCEBM), which has been adapted by the European Association of Endoscopic Surgery. Results Of all the studies included in this review, seven referred to validated simulators. These 7 studies were assigned an average MERSQI score of 8.57 from 18 possible points. None of the studies was randomized or conducted in a high-fidelity environment. The best evidence was provided by the studies with the human placenta model, which received a score of 2b and a degree of recommendation of 3. Conclusion Brazilian simulators can be reproduced in the different laboratories that are available in the country. The average MERSQI score of Brazilian studies is similar to the international average score. New studies should be undertaken to seek greater validation of the simulators and carry out randomized controlled trials.

Objetivo: Analisar as percepções de estudantes, em uma escola médica no interior do estado de Goiás, sobre os fatores influenciadores na escolha ou na repulsa estudantil pela carreira em Medicina de Família e Comunidade. Metodologia: Pesquisa qualitativa, exploratória e transversal. Foi adotada a Análise de Conteúdo, de Laurence Bardin. O instrumento adotado foi um roteiro para entrevista semiestruturada e um questionário socioeconômico. O roteiro possuía perguntas fechadas abordando a preferência do aluno por determinadas especialidades médicas. A partir daí, perguntou-se por que escolheram ou não a Medicina de Família e Comunidade. Roteiro aplicado em 2013, para todos os 42 estudantes do último ano de um curso de medicina. Resultados: Nenhum estudante pesquisado escolheu a Medicina de Família e Comunidade. A relevância social da profissão, a abrangência de diversos problemas na prática clínica, o vínculo contínuo com pacientes, uma exposição maior a esta especialidade e, principalmente, a presença de médicos de família na graduação seriam influências positivas para a escolha destes alunos pela Medicina de Família e Comunidade. O desprestígio na universidade, identificado no discurso de professores e médicos preceptores, além da falta de reconhecimento da sociedade e a baixa remuneração foram os principais fatores desmotivadores na escolha pela área. Conclusão: A valorização da Medicina de Família e Comunidade, com o aumento da participação de mais especialistas no curso de medicina, além de uma valorização na comunidade universitária e na gestão do sistema de saúde podem ser ações que provoquem uma atração maior de estudantes para esta especialidade.
Objective: To analyze the perceptions of students in a medical school in the interior of a state of Goiás, on the factors influencing the choice or rejection of students by Family and Community Medicine as a medical career. Methodology: Qualitative, exploratory and transversal research. Content Analysis was adopted by Laurence Bardin. The instrument adopted was a script for a semi-structured interview and a socioeconomic questionnaire. The script had closed questions about which medical specialty the students were choosing. From then on, was asked why they chose or did not choose the Family and Community Medicine. Roadmap applied in 2013 to all 42 seniors in a medical school. Results: No students studied chose Family and Community Medicine. The social relevance of the specialty, the coverage of several different problems in clinical practice, the continuous link with patients and a greater exposure to this specialty, and especially the presence of experts in the undergraduate would be positive influences for the choice Family and Community Medicine. The lack of prestige in the university, identified in the discourse of preceptor teachers and doctors, in addition to the lack of recognition of society and the low remuneration were the main demotivating factors in this choice. Conclusion: The increase in the participation of more Family and Community Medicine specialists in the medical school, as well as a valuation in the university community and in the management of the health system can be actions that provoke a greater attraction of students to this specialty.

Objective: Identify the prevalence of Actinic Keratosis (CA) in elderly residents in the city of Palmas, TO, Brazil. Method: it is an observational, cross-sectional epidemiologic study, conducted in the city of Palmas from January to June of 2016, with subjects of both sexes, aged above 60 years. Results: two hundred sixty-nine elders were part of this study, most of them aged between 60 and 69 years, with an average age of 72 years. The CA prevalence was 2.3%, mostly women (66.7%), aged between 68 and 91, and who declared themselves white (66.7%). Conclusion: Studies warn about the risk of elderly people developing CA related to solar exposure throughout the life. Although this study did not investigate the life habits related to sun exposure, the results confirm this risk for seniors. This study highlights the importance of preventive skin care, especially related to sun exposure, aiming the CA prevention.
Objetivo: identificar la prevalencia de queratosis actínica (CA) en los adultos mayores residentes en la ciudad de Palmas, Tocantins, Brasil.

This study assessed the contributions of pH and organic matter (OM) on the recovery of infectious human adenovirus 5 (HAdV-5) and genome copies (GCs) in waters that were artificially contaminated with tropical soil. The use of a mathematical equation was proposed based on the flocculation index of clay to assess the recovery of total GCs in these controlled assays. The results suggest that solids in the water reduced the viral genome copy loads per millilitre (GC · mL(-1)) and viral infectivity. OM did not influence the GC · mL(-1) recovery rate (p > 0.05) but led to a 99% (2 log10) reduction in plaque-forming unit counts per millilitre (PFU/mL), which indicates that infectivity and gene integrity were non-related parameters. Our findings also suggest that acidic pH levels hinder viral inactivation and that clay is the main factor responsible for the interactions of HAdV-5 with soil. These findings may be useful for future eco-epidemiological investigations and studies of viral inactivation or even as parameters for future research into water quality analysis and water treatment.

Introdução: O número de viagens nacionais e internacionais cresceu muito nos últimos anos, tanto pelo turismo como por interesses comerciais, militares e/ou humanísticos. Neste contexto, surge a Medicina de Viagem que visa reduzir a morbi-mortalidade associada às viagens utilizando a conscientização e medidas preventivas. Os objetivos do estudo foram avaliar a situação atual da Medicina de Viagem no mundo, identificando as doenças e medidas profiláticas relacionadas à saúde do viajante, os profissionais atuantes e relatar os principais obstáculos enfrentados pelos centros de atendimento aos viajantes. Métodos: Pesquisa sistemática e estruturada da literatura científica, utilizando três bases de dados em ciências da saúde: Lilacs, Medline e SciELO,utilizando-se os seguintes descritores "travel and medicine", "travel and prevention", "travel and disease and Medicine" e "traveler and medicine". Selecionou-se artigos publicados em inglês, espanhol e português, de 2004 e 2008. Resultados: Foram encontrados 1.301 artigos, sendo 184 (14,1%) da Lilacs, 1.087 (83,6%) da Medline e 30 (2,3%) da SciELO. A aplicação do teste de relevância I resultou na seleção de 197 artigos para análise da obra completa. O teste de relevância II, aplicado às 177 obras completas encontradas, resultou na exclusão de 105 artigos. Conclusões: A Medicina de Viagem ainda enfrenta muitos obstáculos, devido principalmente à deficiência de instrumentos de orientação e capacitação e a resistência de profissionais de saúde e viajantes. Devem-se elaborar planos que envolvam entidades de Medicina de Viagem e órgãos governamentais, pois grande parte das doenças que acometem os viajantes pode ser prevenida com medidas simples e de baixo custo.

OBJECTIVE: To identify genetic counseling programs that do not encourage therapeutic abortion for individuals with hemoglobin disorders and/or for their relatives. METHOD: Systematic literature review of articles published from 2001 to 2012 that are located in the PubMed, LILACS, SciELO and SCOPUS databases using keywords in Portuguese, English and Spanish and that met the inclusion and exclusion criteria described on a standardized form. RESULTS: A total of 409 articles were located, but only eight (1.9%) were selected for analysis. CONCLUSION: Although seldom mentioned in the literature, educational/preventive programs targeting hemoglobinopathies are feasible and allow the affected individuals to acquire knowledge on the consequences of this condition and their odds of transmitting it.
