BACKGROUND Eosinophils are granulocytes that rapidly increase frequency in the bloodstream during helminthic infections and allergic responses. They are found in tissue infected by Leishmania during early disease, but their role during infection is not entirely understood. OBJECTIVES We aim to compare the disease due to Leishmania amazonensis in BALB/c and Δdbl-GATA1 mice, which lack eosinophils. METHODS BALB/c and Δdbl-GATA1 mice infected with L. amazonensis were observed for several weeks. The parasite load and dissemination pattern were assessed. FINDINGS The Δdbl-GATA1 mice developed an anticipated dissemination of L. amazonensis and a worsening disease. No differences were found in the lesion development or the parasite load in the footpad among Δdbl-GATA1 mice and BALB/c eight weeks after infection. However, nine weeks after infection, massive growth of metastatic lesions appeared in several parts of the skin in Δdbl-GATA1 mice, weeks earlier than BALB/c. We observed increased parasites in the bloodstream, probably an essential dissemination route. Thirteen weeks after infection, metastatic lesions were found in all Δdbl-GATA1 mice. MAIN CONCLUSION These results suggest a protective role of eosinophils in delaying the disease caused by L. amazonensis, although several limitations of this mice strain must be considered.

ABSTRACT The tropical forest is extremely exploited and fragmented, making it essential to collect native seeds to meet the growing demand for its restoration and maintenance of biodiversity. Thus, the objective is to select potential forest fragments with a higher degree of conservation for seed harvesting, through the use and association of landscape ecology with fuzzy logic. The study was carried out in the watershed of the Itapemirim river. The stages of selection and photointerpretation of the images were carried out; error determination; application of landscape ecology metric indices; application of fuzzy logic in a computational application and validation of the methodology in loco. 7,515 forest fragments were determined, corresponding to 19.21% of the study area, with 89.53% of hits. Fragments smaller than 5 ha are the most fragile and are at risk of extinction, while those larger than 300 ha have a lower risk of extinction, even with the increase in the edge. With the application of fuzzy logic, the mean was between 0.15, standard deviation of 0.24 and the coefficient of variation at 161.73%. Scenario 1 (FLONA of Pacotuba), has 10.25% of families, 25.92% of genera and 33.62% of species more than Scenario 2 (PEAMA Ifes Campus of Alegre), among the identified individuals. The association of landscape ecology techniques and fuzzy logic made it possible to identify fragments with a higher degree of conservation, with potential for harvesting forest seeds.

RESUMO A floresta tropical é extremamente explorada e fragmentada, sendo imprescindível a coleta de sementes nativas, a fim de atender a crescente demanda para sua restauração e manutenção da biodiversidade. Dessa forma, objetiva-se selecionar fragmentos florestais potenciais com maior grau de conservação para a colheita de sementes, via utilização e associação da ecologia da paisagem à lógica Fuzzy. O estudo foi realizado na bacia hidrográfica do rio Itapemirim. Foram realizadas as etapas de seleção e fotointerpretação das imagens; determinação do erro; aplicação dos índices métricos de ecologia da paisagem; aplicação da lógica Fuzzy em aplicativo computacional e validação da metodologia in loco. Foram determinados 7.515 fragmentos florestais, correspondendo a 19,21% da área de estudo, com 89,53% de acertos. Os fragmentos menores que 5 ha são os mais frágeis e possuem risco de extinção, enquanto os maiores que 300 ha possuem menor risco de extinção, mesmo com o aumento da borda. Com a aplicação da lógica Fuzzy, a média ficou entre 0,15, desvio padrão de 0,24 e o coeficiente de variação em 161,73 %. O Cenário 1 (FLONA de Pacotuba) possui 10,25% de famílias, 25,92 % de gêneros e 33,62% de espécies a mais que o Cenário 2 (PEAMA Ifes Campus de Alegre), entre os indivíduos identificados. A associação das técnicas de ecologia da paisagem e lógica Fuzzy possibilitou identificar os fragmentos em maior grau de conservação, com potencial para colheita de sementes florestais.

Abstract Objective The present study aimed to compare the cure rate recovery time and Merle d'Aubigné-Postel functional (MAPF) score after single-stage surgery (C1T) or two-stage surgery (C2T) to treat prosthetic infections of the hip considering sociodemographic and clinical features of the patients. Materials and Methods The present retrospective study occurred in a single center from 2011 to 2014 with 37 studied cases including 26 treated with C1T and 11 with C2T. We compared the cure rate recovery time and MAPF score in the two groups as well as the sociodemographic and clinical features of the patients. We also considered surgical complications and the most common infectious agents. Results The C1T group had a faster functional recovery than the C2T group but there were no significant differences in the cure rate surgical complications or MAPF score. However C1T group patients were significantly younger which may have influenced the outcomes. Staphylococcus spp. was the most common infectious agent (62%). Conclusion Although C2T appears superior regarding infection cure C1T may be preferable for faster functional recovery. However it is critical to consider individual patient characteristics when choosing treatment. Further research with a larger sample size is required to confirm these results.

Resumo Objetivo Comparar a taxa de cura, o tempo de recuperação e a pontuação na escala funcional de Merle d'Aubigné-Postel (EFMA) entre a cirurgia em tempo único (C1T) e a cirurgia em dois tempos (C2T) no tratamento de infecções protéticas do quadril, considerando as características sociodemográficas e clínicas dos pacientes. Materiais e Métodos Foi realizado um estudo retrospectivo num único centro, entre 2011 e 2014, com um total de 37 casos estudados, sendo 26 tratados com C1T e 11 com C2T. Foram comparadas a taxa de cura, o tempo de recuperação e a pontuação EFMA entre os dois grupos, bem como as características sociodemográficas e clínicas dos pacientes. Foram também consideradas as complicações cirúrgicas e o agente infeccioso mais comum. Resultados O grupo C1T teve uma recuperação funcional mais rápida do que o grupo C2T, mas não houve diferenças significativas na taxa de cura, nas complicações cirúrgicas ou na pontuação EFMA. No entanto, o grupo C1T era significativamente mais jovem, o que pode ter influenciado os resultados. Staphylococcus spp. foi o agente infeccioso mais comum (62%). Conclusão Embora a C2T pareça ser superior em termos de cura de infecção, a C1T pode ser preferível para uma recuperação funcional mais rápida. No entanto, as características individuais dos pacientes devem ser consideradas na escolha do tratamento. São necessárias mais pesquisas com um tamanho de amostra maior para confirmar estes resultados.

Abstract Anterior dislocations represent about 96% of total shoulder dislocations, with recurrence/instability being more common in young patients. Injury of other shoulder structures is frequent, namely bony Bankart lesion. However, the association with coracoid apophysis fracture is very rare. The present article describes the clinical case of a 67-year-old man who presented to the emergency department with complaints of persistent omalgia, with acute episodes, beginning after a fall from his own height. The patient also presented history of shoulder trauma 3 months earlier, which was evaluated at another hospital. Shoulder anterior dislocation was observed radiographically, and the computed tomography (CT) confirmed bone erosion of the anteroinferior part of the glenoid (bone loss of about 50% of the anteroposterior diameter in the lower region of the glenoid), with almost complete resorption of the bony Bankart lesion (apparent in later analysis of the radiography of the initial traumatic episode). Connectedly, a transverse fracture of the coracoid apophysis (type II in the Ogawa classification) was diagnosed. The patient was submitted to surgical treatment, with anterior bone stop confection using the remnant of the fractured fragment of the coracoid supplemented by tricortical autologous iliac graft, fixed with cannulated screws (according to the Bristow-Latarjet and Eden-Hybinett techniques). In the postoperative follow-up, a good functional result was observed, with no new episodes of dislocation and no significant pain complaints. A rare association of shoulder lesions is described, and the challenge of their treatment is highlighted, given the late diagnosis, as in the case presented.

Resumo As luxações anteriores representam cerca de 96% do total de luxações do ombro, sendo a recidiva/instabilidade mais comum em pacientes jovens. A lesão de outras estruturas do ombro é frequente, nomeadamente a lesão óssea de Bankart. Contudo, a associação com a fratura da apófise coracoide é muito rara. Este artigo descreve o caso clínico de um homem de 67 anos que recorreu ao serviço de urgência com queixas de omalgia persistente, com episódios de agudização, iniciados após queda da própria altura. O paciente apresentava ainda histórico de trauma do ombro 3 meses antes, avaliado em outro hospital. A luxação anterior do ombro foi constatada radiograficamente, e a tomografia computorizada (TC) do ombro confirmou erosão óssea da vertente anteroinferior da glenoide (perda óssea de cerca de 50% do diâmetro anteroposterior na região inferior da glenoide), com reabsorção quase completa de lesão óssea de Bankart (aparente em análise a posteriori da radiografia do episódio traumático inicial). Associadamente, foi diagnosticada uma fratura transversa da apófise coracoide (tipo II da classificação de Ogawa). O paciente foi submetido ao tratamento cirúrgico, com confecção do batente ósseo anterior utilizando remanescente do fragmento fraturado do coracoide suplementado por enxerto autólogo tricortical do ilíaco, fixados com parafusos canulados (de acordo com as técnicas de Bristow-Latarjet e Eden-Hybinett). No seguimento pós-operatório, foi observado um bom resultado funcional, sem novos episódios de luxação e sem queixas álgicas significativas. Descreve-se uma associação rara de lesões do ombro, e salienta-se o desafio do tratamento das mesmas dado o seu diagnóstico tardio, como no caso apresentado.

ABSTRACT Intra-annual distribution of precipitation in central Amazonia often leads to a short mild dry season and an increase in irradiance, temperature, and vapor pressure deficit; however, the accurate effect of intra-annual microclimatic variability on stem growth is still under investigation. The objective of this study was to determine how stem growth responds to monthly variations in microclimatic factors in the central Amazon. During five years (2008-2012) we measured diameter stem growth of 109 trees (26 species) and used principal component regression to evaluate the effect of microclimatic variability on stem growth in diameter. We found that the mean stem growth in diameter across species increased in response to an increase in rainfall and reference evapotranspiration, but it decreased with a rise in mean and minimum vapor pressure deficit. A contribution of this study is to show that even when irradiance and temperature had no significant effect on stem growth, small changes in vapor pressure deficit significantly affect stem growth. If the dry season becomes longer, as predicted by models, trees currently more sensitive to microclimatic variability associated with droughts would be the most affected by climate changes.

ABSTRACT Introduction: As a health science, dentistry seeks to raise self-esteem and improve patients’ quality of life. However, the emergence of the aesthetic procedure “ear shut,” which proposes correcting protruding ears without surgery, has raised ethical and legal doubts in the dental profession, especially concerning the limits of professional activity. Objective: To conduct a survey of the laws, norms, and resolutions on the area of performance of dental surgeons, as well as to discuss the limits and consequences of their extrapolation from the perspective of the procedure propagated as “ear shut.” Method: A search was carried out for administrative norms on the Federal Council of Dentistry (CFO) websites and the Federal Council of Medicine and legal provisions on the Portal da Legislação website. Results: In the civil sphere, the disclosure of procedures such as the “ear shut” can characterize a promise of result and lead to judicial accountability. Exceeding professional boundaries constitutes an illegal exercise and a crime under the Brazilian Penal Code. In addition to not covering the area of clinical practice of dentists, at the administrative level, CFO Resolutions No. 198/2019 and No. 230/2020 emphasize that ear procedures are not part of the scope of procedures relevant to Dentistry and may lead to ethical infractions and consequent administrative proceedings. Conclusion: At present, based on the skills, prohibitions, rights, and duties of dentists, it can be stated that performing the “ear shut” by these professionals confronts civil, criminal, and administrative obligations.

RESUMO Introdução: Como ciência da saúde, a Odontologia busca elevar a autoestima e melhorar a qualidade de vida dos pacientes. Entretanto, o surgimento do procedimento estético “ear shut”, que propõe a correção da orelha em abano sem cirurgia, gerou dúvidas de ordem ética e legal na classe odontológica, sobretudo no que diz respeito aos limites de atuação profissional. Objetivo: Realizar o levantamento das leis, normativas e resoluções sobre a área de atuação dos cirurgiões-dentistas, bem como discutir os limites e as consequências de sua extrapolação sob a perspectiva do procedimento propagado como “ear shut”. Método: Foi realizada uma busca de normas administrativas nos sites do Conselho Federal de Odontologia (CFO) e do Conselho Federal de Medicina, bem como de dispositivos legais no site Portal da Legislação. Resultados: Em âmbito cível, a divulgação de procedimentos como o “ear shut” pode caracterizar promessa de resultado e levar à responsabilização judicial. Ultrapassar os limites profissionais constitui exercício ilícito e constitui crime segundo o Código Penal Brasileiro. Além de não abranger a área de atuação clínica dos cirurgiões-dentistas, no âmbito administrativo, as Resoluções do CFO N° 198/2019 e N° 230/2020 enfatizam que procedimentos na orelha não compõem o escopo de procedimentos pertinentes à Odontologia, podendo levar a infrações éticas e consequente processo administrativo. Conclusão: No momento atual, com base nas competências, vedações, direitos e deveres dos cirurgiões-dentistas, pode-se afirmar que a realização do “ear shut” por estes profissionais confronta obrigações de ordem cível, penal e administrativa.

Abstract This article presents the Brazilian private insurance market’s actuarial life tables, BR- EMS 2021. Using Bayesian inference on the parameters of the Heligman- Pollard law of mortality and data from 23 insurance groups over 15 years, totaling 3.5 billion registers, the data were corrected through a two hidden-layer neural network. The resulting tables show that the insured population exhibits lower mortality rates than the general Brazilian population, even lower than the national populations of well-developed countries such as the USA. Moreover, besides the expected gender gap in mortality rates, there is a clear distance between the death and survivorship insurance coverage groups. Likewise, the insured population characteristics mitigate well-known regional structural discrepancies in the Brazilian population, indicating that being part of the selected population of insured individuals is thus associated with a more effective protection against death than other outstanding factors such as geographic region of residence.

Resumen Este artículo presenta las tablas de vida del mercado de seguros privados brasileño, BR-EMS 2021. Los datos, obtenidos de 23 grupos de seguros a lo largo de 15 años, totalizando 3,5 mil millones de registros, fueron corregidos usando una red neuronal con dos capas ocultas. Mediante la inferencia bayesiana para estimar los parámetros bajo la ley de mortalidad de Heligman-Pollard, las tablas obtenidas muestran que la población asegurada tiene tasas de mortalidad más bajas que la población general brasileña e incluso más bajas que las poblaciones nacionales de países desarrollados, como los Estados Unidos de Norteamérica. Además de la diferencia de género esperada en las tasas de mortalidad, hay una clara distinción entre las tablas de grupos de cobertura de riesgo y cobertura de sobrevivientes. Asimismo, se demuestra que las tablas regionales de población asegurada no presentan las conocidas discrepancias estructurales regionales en Brasil, lo que indica que participar de la población de asegurados está asociado con una protección contra la muerte más efectiva que otros factores como la región geográfica de residencia.

Resumo Este artigo apresenta as tábuas de vida do mercado de seguros privados brasileiro, BR-EMS 2021. Os dados obtidos de 23 grupos seguradores ao longo de 15 anos, totalizando 3,5 bilhões de registros, foram corrigidos por meio de rede neural com duas camadas ocultas. Usando a inferência bayesiana para estimar os parâmetros sob a lei de mortalidade Heligman-Pollard, as tábuas obtidas mostram que a população segurada apresenta probabilidades de morte mais baixas do que a população brasileira em geral e até mesmo em relação a populações nacionais de países desenvolvidos, como os EUA. Além da esperada diferença de gênero nas taxas de mortalidade, há uma clara distância entre as probabilidades de morte dos grupos de cobertura de risco e cobertura de sobrevivência. Da mesma forma, é demonstrado que as tábuas regionais da população segurada não apresentam as discrepâncias regionais conhecidas no Brasil, indicando que fazer parte da população selecionada de segurados está associado a um fator de proteção mais eficaz do que outros fatores, como a região geográfica de residência.

ABSTRACT: We investigated an unusual report of localized necrotizing periodontitis coinfection in patients with mild COVID-19. Male patient, 30 years old, with previous medical history of hypovitaminosis, immunized with two doses of the Pfizer® vacci ne, attended in a dental college in northern Brazil with an acute dental emergency reporting itching, halitosis, intense gingival p ain and spontaneous bleeding, mild fever of 37.8ºC, dry cough, muscle pain and nausea. Metronidazole and chlorhexidine were prescribed to improve the necrotizing condition, to treat periodontitis scaling and root planing (SRP) were performed associated with chlo rhexidine irrigation and oral hygiene instructions, which treated the patients conditions. COVID-19 coinfections are possible, specially, oral bacterial infections which is demonstrated in this report, so correct treatment is necessary for both infections. This letter d escribes the first known occurrence of severe localized necrotizing periodontitis in the urban area of Brazil's Amazon region.

RESUMEN: Investigamos un reporte inusual de coinfección de periodontitis necrotizante localizada en pacientes con COVID-19 con síntomas leves: Paciente masculino, de 30 años, con antecedentes médicos de hipovitaminosis, inmunizado con dos dosis de la vacuna Pfizer®, atendido en una facultad de odontología en el norte Brasil, con urgencia dental aguda reportando prurito, halitosis, dolor gingival intenso y sangrado espontáneo, fiebre leve de 37,8 ºC, tos seca, mialgias y náuseas. Se prescribió metronidazol y clorhexidina para mejorar el cuadro necrosante, para tratar la periodontitis se realizó raspado y alisado radicular (SRP) asociado a irrigación con clorhexidina e instrucciones de higiene oral. Las coinfecciones por COVID- 19 son posibles, especialmente las infecciones bacterianas orales, lo cual se demuestra en este reporte, por lo que es necesario un correcto tratamiento de ambas infecciones. Esta carta describe la primera aparición conocida de periodontitis necrotizante severa de un paciente del área urbana de la región amazónica de Brasil.

ABSTRACT The objective of this study was to evaluate the microtensile bond strength (μTBS) to dentin of two universal adhesive systems: Single Bond Universal (SBU) and Ambar Universal (AU), used in different adhesion strategies. Materials and Method: Thirty-six human teeth were prepared (n=6) and treated following different adhesive strategies: G1: SBU-etch-and-rinse, applied on dry dentin; G2: SBUetch- and-rinse, applied on moist dentin; G3: SBU-self-etching; G4: AU-etch-and-rinse, applied on dry dentin; G5: AU-etch-and-rinse, applied on moist dentin; G6: AU-self-etching. The specimens were submitted to μTBS test, failure analysis, and scanning electron microscopy (SEM). Data were analyzed with ANOVA and Tukey’s tests (p<0.05). Results: Microtensile bond strength was significantly lower in G1 than G2 and G3. AU adhesive performed worse than the SBU system, except in G5. Cohesive and mixed failures predominated in G1 and G2, while adhesive failures predominated in G3 and G5. Conclusions: Universal adhesives are an interesting innovation, but there are still doubts about their performance, mainly regarding the different protocols provided by the manufacturers. The conventional adhesive strategy on moist dentin demonstrated higher μTBS for both adhesives. The use of the selfetching strategy with the SBU showed promising results.

RESUMO O objetivo deste estudo foi avaliar a resistência de união à microtração (μTBS) de dois sistemas adesivos universais: Single Bond Universal (SBU) e Ambar Universal (AU), utilizados em diferentes estratégias de adesão. Materiais e método: 36 dentes humanos foram preparados (n=6) e tratados seguindo diferentes estratégias adesivas: G1: SBU-condicionamento e enxágue, aplicado sobre dentina seca; G2: SBU-condicionamento e enxágue, aplicado sobre dentina úmida; G3: SBU-autocondicionante; G4: AU-condicionamento e enxágue, aplicado em dentina seca; G5: AU-condicionamento e enxágue, aplicado sobre dentina úmida; G6: AU-autocondicionante. Os espécimes foram submetidos ao teste de μTBS, análise de falhas e microscopia eletrônica de varredura (SEM). Os dados foram analisados com os testes ANOVA e Tukey (p<0,05). Resultados: A resistência de união à microtração de G1 foi significativamente menor que G2 e G3. O adesivo AU teve um desempenho pior que o sistema SBU, com exceção do G5. Falhas coesivas e mistas predominaram em G1 e G2 enquanto G3 e G5 apresentaram predominância de falhas adesivas. Conclusões: Os adesivos universais representam uma inovação interessante, mas ainda há dúvidas sobre seu desempenho, principalmente em relação aos diferentes protocolos fornecidos pelos fabricantes. A estratégia adesiva convencional em dentina úmida demonstrou maior μTBS para ambos os adesivos. O uso da estratégia autocondicionante com a SBU apresentou resultados promissores.

ABSTRACT The production of fingerlings on a large scale is one of the biggest challenges for grouper aquaculture development. Groupers may be more susceptible to skeletal anomalies due to their complex skeleton formation ontogenesis. Such anomalies are normally associated with inadequate larviculture protocols for marine fish. The present study aimed to record the occurrence of skeletal anomalies in dusky grouper Epinephelus marginatus. Different degrees of kyphosis, lordosis, and scoliosis were identified. After the larviculture period (60 days), 42% of the dusky grouper presented skeletal anomalies. Therefore, we have concluded that the current protocol for the dusky grouper larviculture must be re-examined, especially to determine a more appropriate water flow in the tanks.

ABSTRACT BACKGROUND: Although autonomic dysfunction has been shown to be associated with liver cirrhosis, the prevalence and prognostic implications are unclear. Abnormal heart rate variability (HRV), a measure of autonomic function, has not been well investigated in cirrhosis. OBJECTIVE: To evaluate the prevalence of high-risk HRV parameters in a cohort of cirrhotic patients and their association with cardiac dysfunction and mortality. DESIGN AND SETTING: Prospective observational study conducted in the Federal University of São Paulo. METHOD: A cohort of 120 patients, comprising 17 healthy controls and 103 cirrhotic outpatients, was evaluated and followed for 10 months. HRV analysis was based on 24-hour Holter monitoring and defined using time-domain and frequency-domain parameters. RESULTS: The HRV parameters were statistically lower in cirrhotic patients than in healthy subjects. High-risk HRV parameters were prevalent, such that 64% had at least one high-risk parameter. Time-domain parameters correlated with Child scores (P < 0.0001). In regression models, HRV parameters were independent predictors of diastolic dysfunction and mortality. During 10 months of follow-up, there were 11 deaths, all of patients with at least one high-risk HRV parameter. Kaplan-Meier analysis estimated low survival rates among patients with standard deviation of normal-to-normal RR intervals (SDNN) < 100. CONCLUSION: Reduced HRV is prevalent in liver cirrhosis and is related to cardiac dysfunction, severity of liver disease and mortality. Abnormal high-risk HRV parameters are prevalent among cirrhotic patients and are also predictors of mortality. Our findings highlight the need for a more careful cardiac evaluation of cirrhotic patients.

Resumo: Introdução: O aneurisma da aorta abdominal é uma entidade prevalente no mundo ocidental, com elevada mortalidade associada à rotura do aneurisma. Os programas de rastreio assim como a cirurgia eletiva podem prevenir este evento com elevado risco de vida. Com este trabalho pretendemos avaliar se os internos de Medicina Interna são capazes de realizar ecografia abdominal para rastreio de aneurisma da aorta abdominal, e com isso aumentar a nossa precisão diagnóstica desta condição potencialmente ameaçadora de vida. Material e Métodos: Cinco internos de Medicina Interna, sem experiência prévia em ecografia, rastrearam para aneurisma da aorta abdominal, homens com mais de 65 anos, admitidos no internamento de Medicina Interna. Os doentes foram avaliados em dois tempos diferentes por dois internos de Medicina Interna, e um conjunto de doentes foi também avaliado por um cirurgião vascular ou por tomografia computadorizada abdominal (sendo ambas consideradas as avaliações gold standard). A concordância entre ambas avaliações dos internos de Medicina, e dos internos de Medicina e as avaliações gold standard foram analisadas. Resultados: Foram avaliados 98 doentes e diagnosticados um total de 8 aneurismas da aorta abdominal, perfazendo uma prevalência de 8,2%. Foi obtida uma boa concordância no que diz respeito à presença de aneurisma da aorta abdominal e à sua medição entre as avaliações dos internos de Medicina Interna (κ = 0,918, p < 0,01) e entre os internos de Medicina Interna e as avaliações gold standard (κ = 0,950, p < 0,01). Discussão e Conclusão: A prevalência do aneurisma da aorta abdominal no nosso estudo foi elevada. Os internos de Medicina Interna são capazes de diagnosticar esta entidade com precisão. O rastreio oportunístico e à cabeceira do doente, pode ser realizado durante o internamento na Medicina Interna, providenciando um diagnóstico precoce, com possibilidade de referenciação para cirurgia eletiva de reparação.

Abstract Introduction: Abdominal aortic aneurysm is a prevalent disease in western world, with a high mortality rate when rupture occurs. Screening programs and elective surgery may prevent such a life-threatening event. We pretend to evaluate if internal medicine residents would be able to perform quality abdominal ultrasound for abdominal aortic aneurysm screening, and therefore increase our diagnostic accuracy of this life-threatening condition. Material and Methods: Five internal medicine residents without previous experience in ultrasound screened men over 65 years admitted to Internal Medicine wards for Abdominal Aortic Aneurysm. The patients were evaluated in different times by two internal medicine residents, and a subset of patients was also evaluated by vascular surgery attendant or abdominal computed tomography scan (established as gold standard evaluations). Agreement between both internal medicine resident’s observations and internal medicine residents’ and gold standard evaluations were analyzed. Results: A total of 98 patients were evaluated, with 8 abdominal aortic aneurysms diagnosed, resulting in an 8.2% prevalence. There was good agreement regarding Abdominal Aortic Aneurysm presence and measurement between internal medicine residents’ examinations (κ = 0.918, p < 0.01) and internal medicine residents’/gold standard (κ = 0.950, p < 0.01). Discussion and Conclusion: Abdominal aortic aneurysm prevalence in our study was high. Internal medicine residents were able to accurately diagnose aortic abdominal aneurysm. Point of care opportunistic aortic abdominal aneurysm screening can be performed in Internal Medicine wards, providing an early diagnosis and referral for elective repair surgery.

Abstract Introduction: We investigated the clinical course and outcomes of patients submitted to cardiovascular surgery in Brazil and who had developed symptoms/signs of coronavirus disease 2019 (COVID-19) in the perioperative period. Methods: A retrospective multicenter study including 104 patients who were allocated in three groups according to time of positive real time reverse transcriptase-polymerase chain reaction (RT-PCR) for the SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2): group 1, patients who underwent cardiac surgery > 10 days after positive RT-PCR; group 2, patients with a positive RT-PCR within 10 days before or after surgery; group 3, patients who presented positive RT-PCR > 10 days after surgery. The primary outcome was mortality and secondary outcomes were postoperative complications, intensive care unit (ICU) length of stay, and postoperative days of hospitalization. Results: The three groups were similar with respect to age, the European System of Cardiac Operative Risk Evaluation score, and comorbidities, except hypertension. Postoperative complications and death were significantly higher in groups 2 and 3 than in group 1, and no significant difference between groups 2 and 3 was seen. Group 2 showed a high prevalence of surgery performed as an urgent procedure. Although no significant differences were observed in ICU length of stay, total postoperative hospitalization time was significantly higher in group 3 than in groups 1 and 2. Conclusion: COVID-19 affecting the postoperative period of patients who underwent cardiovascular surgery is associated with a higher rate of morbidity and mortality. Delaying procedures in RT-PCR-positive patients may help reduce risks of perioperative complications and death.

Electrical and magnetic brain stimulation techniques present distinct mechanisms and efficacy in the acute treatment of depression. This was an umbrella review of meta-analyses of randomized controlled trials of brain stimulation techniques for managing acute major depressive episodes. A systematic review was performed in the PubMed/MEDLINE databases from inception until March 2020. We included the English language meta-analysis with the most randomized controlled trials on the effects of any brain stimulation technique vs. control in adults with an acute depressive episode. Continuous and dichotomous outcomes were assessed. A Measurement Tool to Assess Systematic Reviews-2 was applied and the credibility of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation framework. Seven meta-analyses were included (5,615 patients), providing evidence for different modalities of brain stimulation techniques. Three meta-analyses were evaluated as having high methodological quality, three as moderate, and one as low. The highest quality of evidence was found for high frequency-repetitive transcranial magnetic stimulation (rTMS), transcranial direct current stimulation, and bilateral rTMS. There is strong clinical research evidence to guide future clinical use of some techniques. Our results confirm the heterogeneity of the effects across these techniques, indicating that different mechanisms of action lead to different efficacy profiles.

Abstract Background: There is a lack of information on the role of chronic use of hydroxychloroquine during the SARS-CoV-2 outbreak. Our aim was to compare the occurrence of COVID-19 between rheumatic disease patients on hydroxychloroquine with individuals from the same household not taking the drug during the first 8 weeks of community viral transmission in Brazil. Methods: This baseline cross-sectional analysis is part of a 24-week observational multi-center study involving 22 Brazilian academic outpatient centers. All information regarding COVID-19 symptoms, epidemiological, clinical, and demographic data were recorded on a specific web-based platform using telephone calls from physicians and medical students. COVID-19 was defined according to the Brazilian Ministry of Health (BMH) criteria. Mann-Whitney, Chi-square and Exact Fisher tests were used for statistical analysis and two binary Final Logistic Regression Model by Wald test were developed using a backward-stepwise method for the presence of COVID-19. Results: From March 29th to May 17st, 2020, a total of 10,443 participants were enrolled, including 5166 (53.9%) rheumatic disease patients, of whom 82.5% had systemic erythematosus lupus, 7.8% rheumatoid arthritis, 3.7% Sjögren’s syndrome and 0.8% systemic sclerosis. In total, 1822 (19.1%) participants reported flu symptoms within the 30 days prior to enrollment, of which 3.1% fulfilled the BMH criteria, but with no significant difference between rheumatic disease patients (4.03%) and controls (3.25%). After adjustments for multiple confounders, the main risk factor significantly associated with a COVID-19 diagnosis was lung disease (OR 1.63; 95% CI 1.03-2.58); and for rheumatic disease patients were diagnosis of systemic sclerosis (OR 2.8; 95% CI 1.19-6.63) and glucocorticoids above 10 mg/ day (OR 2.05; 95% CI 1.31-3.19). In addition, a recent influenza vaccination had a protective effect (OR 0.674; 95% CI 0.46-0.98). Conclusion: Patients with rheumatic disease on hydroxychloroquine presented a similar occurrence of COVID-19 to household cohabitants, suggesting a lack of any protective role against SARS-CoV-2 infection.
