A cardiomiopatia hipertrófica (CMH) é uma forma de doença do músculo cardíaco de causa genética, caracterizada pela hipertrofia das paredes ventriculares. O diagnóstico requer detecção por métodos de imagem (Ecocardiograma ou Ressonância Magnética Cardíaca) de qualquer segmento da parede do ventrículo esquerdo com espessura > 15 mm, sem outra causa provável. A análise genética permite identificar mutações de genes codificantes de diferentes estruturas do sarcômero responsáveis pelo desenvolvimento da CMH em cerca de 60% dos casos, permitindo o rastreio de familiares e aconselhamento genético, como parte importante do manejo dos pacientes e familiares. Vários conceitos sobre a CMH foram recentemente revistos, incluindo sua prevalência de 1 em 250 indivíduos, não sendo, portanto, uma doença rara, mas subdiagnosticada. A vasta maioria dos pacientes é assintomática. Naqueles sintomáticos, a obstrução do trato de saída do ventrículo esquerdo (OTSVE) é o principal distúrbio responsável pelos sintomas, devendo-se investigar a sua presença em todos os casos. Naqueles em que o ecocardiograma em repouso ou com Manobra de Valsalva não detecta gradiente intraventricular significativo (> 30 mmHg), devem ser submetidos à ecocardiografia com esforço físico para detecção da OTSVE. Pacientes com sintomas limitantes e grave OTSVE, refratários ao uso de betabloqueadores e verapamil, devem receber terapias de redução septal ou uso de novas drogas inibidoras da miosina cardíaca. Por fim, os pacientes adequadamente identificados com risco aumentado de morta súbita podem receber medida profilática com implante de cardiodesfibrilador implantável (CDI).
La miocardiopatía hipertrófica (MCH) es una forma de enfermedad cardíaca de origen genético, caracterizada por el engrosamiento de las paredes ventriculares. El diagnóstico requiere la detección mediante métodos de imagen (Ecocardiograma o Resonancia Magnética Cardíaca) que muestren algún segmento de la pared ventricular izquierda con un grosor > 15 mm, sin otra causa probable. El análisis genético permite identificar mutaciones en genes que codifican diferentes estructuras del sarcómero responsables del desarrollo de la MCH en aproximadamente el 60% de los casos, lo que permite el tamizaje de familiares y el asesoramiento genético, como parte importante del manejo de pacientes y familiares. Varios conceptos sobre la MCH han sido revisados recientemente, incluida su prevalencia de 1 entre 250 individuos, por lo tanto, no es una enfermedad rara, sino subdiagnosticada. La gran mayoría de los pacientes son asintomáticos. En los casos sintomáticos, la obstrucción del tracto de salida ventricular izquierdo (TSVI) es el trastorno principal responsable de los síntomas, y su presencia debe investigarse en todos los casos. En aquellos en los que el ecocardiograma en reposo o la maniobra de Valsalva no detecta un gradiente intraventricular significativo (> 30 mmHg), deben someterse a ecocardiografía de esfuerzo para detectar la obstrucción del TSVI. Los pacientes con síntomas limitantes y obstrucción grave del TSVI, refractarios al uso de betabloqueantes y verapamilo, deben recibir terapias de reducción septal o usar nuevos medicamentos inhibidores de la miosina cardíaca. Finalmente, los pacientes adecuadamente identificados con un riesgo aumentado de muerte súbita pueden recibir medidas profilácticas con el implante de un cardioversor-desfibrilador implantable (CDI).
Hypertrophic cardiomyopathy (HCM) is a form of genetically caused heart muscle disease, characterized by the thickening of the ventricular walls. Diagnosis requires detection through imaging methods (Echocardiogram or Cardiac Magnetic Resonance) showing any segment of the left ventricular wall with a thickness > 15 mm, without any other probable cause. Genetic analysis allows the identification of mutations in genes encoding different structures of the sarcomere responsible for the development of HCM in about 60% of cases, enabling screening of family members and genetic counseling, as an important part of patient and family management. Several concepts about HCM have recently been reviewed, including its prevalence of 1 in 250 individuals, hence not a rare but rather underdiagnosed disease. The vast majority of patients are asymptomatic. In symptomatic cases, obstruction of the left ventricular outflow tract (LVOT) is the primary disorder responsible for symptoms, and its presence should be investigated in all cases. In those where resting echocardiogram or Valsalva maneuver does not detect significant intraventricular gradient (> 30 mmHg), they should undergo stress echocardiography to detect LVOT obstruction. Patients with limiting symptoms and severe LVOT obstruction, refractory to beta-blockers and verapamil, should receive septal reduction therapies or use new drugs inhibiting cardiac myosin. Finally, appropriately identified patients at increased risk of sudden death may receive prophylactic measure with implantable cardioverter-defibrillator (ICD) implantation.

RESUMO Objetivo: Comparar os achados oculares em longo prazo de crianças que se submeteram à cirurgia de catarata congênita antes dos dois anos de idade e receberam uma injeção intracameral de triancinolona no intraoperatório ou usaram prednisolona oral no pós-operatório para modular a inflamação ocular. Métodos: Neste estudo prospectivo de coorte, todos os pacientes que participaram de um ensaio clínico anterior, que analisou os resultados cirúrgicos de 1 ano da cirurgia de catarata congênita usando triancinolona intracameral (Grupo de Estudo) ou prednisolona oral (Grupo Controle), eram elegíveis para participar. Os prontuários médicos dos pacientes foram revisados e as crianças foram submetidas a um exame oftalmológico completo no acompanhamento final. As principais medidas de desfecho foram: achados biomicroscópicos, pressão intraocular, espessura central da córnea, a necessidade de intervenções cirúrgicas adicionais e achados compatíveis com glaucoma. Resultados: Vinte e seis olhos (26 pacientes) foram incluídos (Grupo de Estudo = 11 olhos; Grupo de Controle = 15 olhos). O seguimento médio foi de 8,2 ± 1,2 anos e 8,1 ± 1,7 anos nos Grupos de Estudo e Controle, respectivamente (p=0,82). Todos os olhos apresentavam lente intraocular centrada. Não houve diferença estatisticamente significativa entre os grupos com relação à presença de sinéquia posterior (p=0,56), pressão intraocular (p=0,49) ou espessura central da córnea (p=0,21). Nenhum dos olhos preencheu os critérios diagnósticos para glaucoma, apresentou opacificação secundária do eixo visual ou foi reoperado. Conclusão: Os achados oculares em longo prazo de crianças que se submeteram à cirurgia de catarata congênita e receberam uma injeção intracameral de triancinolona no intraoperatório foram semelhantes aos que usaram prednisolona oral no pós-operatório para modular a inflamação ocular, sugerindo que a triancinolona intracameral pode substituir a prednisolona oral na cirurgia de catarata congênita, facilitando o tratamento pós-operatório e a adesão ao mesmo.

ABSTRACT Purpose: To compare the long-term ocular findings of children that were operated of congenital cataract before the age of two and that received an intraoperative intracameral triamcinolone injection or used postoperative oral prednisolone to modulate ocular inflammation. Methods: All patients who had previously participated in a clinical trial that analyzed the 1-year surgical outcomes of congenital cataract surgery utilizing intracameral triamcinolone (study group) or oral prednisolone (control group) were eligible to participate in this prospective cohort research. Patients’ medical records were reviewed, and the children underwent a complete ophthalmologic exam on final follow-up. Biomicroscopic findings, intraocular pressure, central corneal thickness, the need for additional surgical interventions, and findings compatible with glaucoma were the primary end measures. Results: Twenty-six eyes (26 patients) were included (study group = 11 eyes; control group = 15 eyes). The mean follow--up was 8.2 ± 1.2 years and 8.1 ± 1.7 years in the study and control groups, respectively (p=0.82). All eyes presented a centered intraocular lens. There was no statistically significant difference between the groups with regards to the presence of posterior synechia (p=0.56), intraocular pressure (p=0.49), or central corneal thickness (p=0.21). None of the eyes fulfilled the glaucoma diagnostic criteria, presented secondary visual axis obscuration, or were reoperated. Conclusion: The long--term ocular findings of children that underwent congenital cataract surgery and received an intraoperative intracameral triamcinolone injection were similar to those that used postoperative oral prednisolone to modulate ocular inflammation. This suggests that intracameral triamcinolone may substitute oral prednisolone in congenital cataract surgery, facilitating the postoperative treatment regimen and compliance.

Abstract Background: In this experimental protocol, we evaluated the immediate and delayed repair of the buccal branch of the facial nerve (BBFN) with heterologous fibrin biopolymer (HFB) as a coaptation medium and the use of photobiomodulation (PBM), performing functional and histomorphometric analysis of the BBFN and perioral muscles. Methods: Twenty-eight rats were divided into eight groups using the BBFN bilaterally (the left nerve was used for PBM), namely: G1 - control group, right BBFN (without injury); G2 - control group, left BBFN (without injury + PBM); G3 - Denervated right BBFN (neurotmesis); G4 - Denervated left BBFN (neurotmesis + PBM); G5 - Immediate repair of right BBFN (neurotmesis + HFB); G6 - Immediate repair of left BBFN (neurotmesis + HFB + PBM); G7 - Delayed repair of right BBFN (neurotmesis + HFB); G8 - Delayed repair of left BBFN (neurotmesis + HFB + PBM). Delayed repair occurred after two weeks of denervation. All animals were sacrificed after six weeks postoperatively. Results: In the parameters of the BBFN, we observed inferior results in the groups with delayed repair, in relation to the groups with immediate repair, with a significant difference (p < 0.05) in the diameter of the nerve fiber, the axon, and the thickness of the myelin sheath of the group with immediate repair with PBM compared to the other experimental groups. In measuring the muscle fiber area, groups G7 (826.4 ± 69.90) and G8 (836.7 ± 96.44) were similar to G5 (882.8 ± 70.51). In the functional analysis, the G7 (4.10 ± 0.07) and G8 (4.12 ± 0.08) groups presented normal parameters. Conclusion: We demonstrated that delayed repair of BBFN is possible with HFB, but with worse results compared to immediate repair, and that PBM has a positive influence on nerve regeneration results in immediate repair.

Resumo A literatura científica sobre anomalias em anfíbios é vasta, mas casos registrados de heterocromia ocular em anfíbios estão quase ausentes, mesmo considerando registros anedóticos. No território brasileiro, apenas dois casos de heterocromia ocular foram registrados anteriormente para anfíbios, ambos para anuros, o primeiro para a Mata Atlântica do nordeste do Brasil e o segundo para a região amazônica do norte do Brasil. No presente relato, descrevemos dois casos de heterocromia ocular no hilídeo Boana albomarginata, ambos no bioma Mata Atlântica, estado da Bahia, nordeste do Brasil, representando o primeiro registro de heterocromia ocular para esta espécie e o terceiro caso registrado para uma espécie de anfíbio no Brasil. Um olho de cada exemplar observado apresentava atipicamente íris de cor azul chamativa e homogênea, preenchendo toda sua superfície ou apenas a metade inferior, representando casos de heterocromia completa e setorial, respectivamente. Além disso, a não-usual íris azul só esteve detectável sob a luz do dia, quando a cor de fundo da íris era branca. À noite, a cor de fundo padrão da íris cobreada ou dourada permaneceu inalterada e a cor azul não pôde ser detectada. Nenhuma outra anomalia detectável ou comportamento incomum foi observada para ambos os exemplares. Este é o primeiro relato de heterocromia ocular em anfíbios representado por uma cor azul bem-marcada e limitada a um padrão diurno de cor da íris. Mais estudos são necessários para determinar a natureza desta anomalia e suas potenciais consequências para o indivíduo e para a espécie. vasta ausentes anedóticos brasileiro anuros albomarginata Bahia homogênea inferior setorial respectivamente disso nãousual usual dia branca noite detectada exemplares bemmarcada bem marcada
Abstract The scientific literature on amphibian anomalies is large, but registered cases of amphibians’ ocular heterochromia are almost absent, even considering anecdotal records. In the Brazilian territory, only two cases of ocular heterochromia were formerly registered for amphibians, both for anurans, the first from the Atlantic Forest of northeastern Brazil and the second from the Amazonian region of northern Brazil. In the present account, we report two cases of ocular heterochromia in the hylid treefrog Boana albomarginata, both from the Atlantic Forest biome, Bahia state, northeastern Brazil, representing the first record of ocular heterochromia for this species and the third case registered for an amphibian’s species in Brazil. One eye of each observed specimen had an unusually flashy and homogeneous blue-colored iris, filling its entire surface or only its lower half, representing cases of complete and sectoral heterochromia, respectively. Furthermore, the unusual flashy blue iris was only detectable during daylight, when the iris background color was white. At night, the standard copper to golden iris background color remains unchanged, and the blue color cannot be detected. No other detectable anomalies or unusual behaviors were observed for both specimens. This is the first report of amphibian ocular heterochromia represented by a flashy blue color iris and limited to a daylight iris color pattern. Further studies are necessary to determine the nature of this anomaly and its potential consequences for the specimen and the species. large amphibians absent records territory anurans account albomarginata biome state s bluecolored colored half respectively Furthermore white night unchanged detected specimens pattern

RESUMO A couve-de-folhas é uma das hortaliças folhosas mais cultivadas no Brasil, porém seu melhoramento ainda é limitado. Portanto, é crucial desenvolver pesquisas que explorem a diversidade genética dos germoplasmas disponíveis, visando estabelecer cruzamentos promissores nas populações estudadas. O objetivo deste estudo foi avaliar a divergência genética entre progênies de meios-irmãos de couve-de-folhas obtidas por seleção recorrente e selecionar as progênies mais promissoras para compor uma população recombinante utilizando métodos multivariados. Como tratamentos, foram avaliadas plantas obtidas a partir de sementes de 25 progênies de meio-irmãos pré-selecionadas e três cultivares comerciais. Para produzir essas sementes, clones das progênies foram submetidos a recombinação em 2018, com subsequente seleção de sementes de plantas com desempenho agronômico superior. Foram avaliadas doze características quantitativas e quinze qualitativas em cada parcela, totalizando vinte e sete características avaliadas. O estudo da divergência genética foi realizado através de variáveis canônicas para os dados quantitativos. O método UPGMA foi aplicado a dados quantitativos, qualitativos e combinados, utilizando-se a distância genética de Mahalanobis. As três primeiras variáveis canônicas explicaram 73,75% da variação total acumuladas quando comparadas às cultivares comerciais, e 55,29% quando considerado exclusivamente as progênies meios-irmãos. As progênies de meios-irmãos P1, P2, P3, P4, P5, P9, P11, P15, P16, P18, P20, P22, P23, P24 e P25 foram as mais divergentes e devem ser priorizadas na composição da população recombinante para o terceiro ciclo de seleção recorrente, pois além de variação genética, também apresentam características de interesse ao programa de melhoramento genético da couve. As cultivares comerciais apresentaram-se como os genótipos mais divergentes e deverão ser incluídas no próximo ciclo de recombinação. couvedefolhas couve folhas Brasil limitado Portanto disponíveis estudadas meiosirmãos meios irmãos multivariados tratamentos 2 meioirmãos meio préselecionadas pré selecionadas 2018 superior parcela quantitativos combinados utilizandose se Mahalanobis 7375 73 75 73,75 5529 55 29 55,29 meiosirmãos. irmãos.

ABSTRACT Kale is one of the most widely cultivated leafy vegetables in Brazil, but its breeding genetic is still limited. Therefore, it is crucial to develop research that explores the genetic diversity of the available germplasms, aiming to establish promising crosses in the studied populations. The present study aimed to evaluate the genetic divergence between half-sibling progenies of kale, obtained through recurrent selection, using multivariate methods to select the most promising progenies for forming a recombinant population. The plants obtained from the seeds of 25 pre-selected half-sibling progenies and three commercial cultivars were evaluated as treatment groups. These seeds were produced in 2018 by subjecting the clones of the progenies to recombination, followed by the selection of appropriate seeds from plants with superior agronomic performance. In the present study, plants in each plot were evaluated for twelve quantitative and fifteen qualitative traits. Genetic divergence was studied based on canonical variables to obtain quantitative data. The UPGMA method was applied to the quantitative, qualitative, and combined data, and Mahalanobis genetic distance was adopted. The first three canonical variables explained 73.75% of the total cumulative variation compared to the commercial cultivars and 55.29% when considering the half-sibling progenies exclusively. The half-sibling progenies P1, P2, P3, P4, P5, P9, P11, P15, P16, P18, P20, P22, P23, P24, and P25 were the most divergent and should, therefore, be prioritized when composing the recombinant population for the third cycle of recurrent selection because, in addition to genetic variation, these progenies also present characteristics of interest to the kale genetic breeding program. The commercial cultivars exhibited the most divergent genotypes and should, therefore, be included in the next recombination cycle.

RESUMO Propósito Os desastres ambientais têm causado vários danos humanos, ecológicos e econômicos em todo o Mundo. Para reduzir os potenciais danos e salvar vidas a curto prazo, surgem os voluntários envolvidos no apoio em situações de desastre. Diante desse cenário, estudos sobre voluntários que atuam em contextos de desastres no Brasil revelam-se um tema de pesquisa interessante e necessário. Design/metodologia/abordagem Esta pesquisa adotou uma metodologia qualitativa, com 16 entrevistas semiestruturadas e em profundidade. O processo de seleção dos participantes foi realizado por meio da técnica de amostragem bola de neve, concentrando-se em voluntários que atuam em resposta a desastres no contexto brasileiro. Uma análise de conteúdo detalhada foi realizada. As motivações descobertas foram então cuidadosamente comparadas e contrastadas com o Inventário de Funções do Voluntariado (VFI), que é baseado na teoria funcionalista psicológica do voluntariado. Descobertas Os resultados deste estudo avançam a literatura ao confirmar quatro motivações dos voluntários para agir em desastres como os identificados no VFI - valores, aprimoramento, proteção e social. Além disso, este estudo contribui ao trazer à tona duas novas motivações, conhecimento e prontidão que emergiram da análise dos dados de conteúdo. O estudo também avança ao agrupar os perfis de comportamento determinados a partir dessas motivações como especialista, sensível, altruísta, iniciante e social. Originalidade/valor Com base nos resultados, foi proposto um Quadro de Voluntariado em Desastres que serve de base para o desenvolvimento de políticas públicas para o governo e auxilia as instituições que trabalham na gestão de desastres na atração de novos voluntários. humanos Mundo prazo desastre cenário revelamse revelam se necessário Designmetodologiaabordagem Design abordagem qualitativa 1 profundidade neve concentrandose concentrando brasileiro realizada VFI, , (VFI) voluntariado valores aprimoramento social disso especialista sensível altruísta Originalidadevalor Originalidade valor (VFI
ABSTRACT Purpose Environmental disasters have caused various human, ecological, and economic damage worldwide. To reduce the potential damage and save lives in the short term, the volunteers are involved in support in disaster situations. Given this scenario, studies on volunteers who work in disaster contexts in Brazil proved to be an interesting and necessary research topic. Design/methodology/approach This research employed a qualitative methodology, utilizing 16 semi-structured, in-depth interviews to gather data. The process of selecting participants was carried out through the snowball sampling technique, focusing on individuals volunteering in disaster response within the Brazilian setting. Following data collection, a thorough content analysis was undertaken. The motivations uncovered through this analysis were then meticulously compared and contrasted against the Volunteer Functions Inventory (VFI), which is rooted in the psychological functionalist theory of volunteerism. Findings The findings of this study advance the literature by confirming four motivations for volunteers to act in disasters, as identified in the VFI: values, enhancement, protective, and social. Additionally, this study contributes by bringing to light two new motivations, knowledge, and readiness, which emerged from the content data analysis. The study also advances by clustering the behavior profiles determined from these motivations as expert, sensitive, altruistic, beginner, and social. Originality/value Based on the results, a Disaster Volunteer Framework was proposed, which serves as a basis for developing public policies for the government and assists institutions that work in disaster management in attracting new volunteers. human ecological worldwide term situations scenario topic Designmethodologyapproach Design methodology approach 1 semistructured, semistructured semi structured, structured semi-structured indepth depth technique setting collection undertaken VFI, VFI , (VFI) volunteerism values enhancement protective social Additionally knowledge readiness expert sensitive altruistic beginner Originalityvalue Originality value results proposed (VFI

Abstract Background Patients with immune-mediated rheumatic diseases (IMRDs) have been prioritized for COVID-19 vaccination to mitigate the infection severity risks. Patients with rheumatoid arthritis (RA) are at a high risk of severe COVID-19 outcomes, especially those under immunosuppression or with associated comorbidities. However, few studies have assessed the safety of the COVID-19 vaccine in patients with RA. Objective To evaluate the safety of vaccines against SARS-CoV-2 in patients with RA. Methods This data are from the study “Safety and Efficacy on COVID-19 Vaccine in Rheumatic Diseases,” a Brazilian multicentric prospective phase IV study to evaluate COVID-19 vaccine in IMRDs in Brazil. Adverse events (AEs) in patients with RA of all centers were assessed after two doses of ChAdOx1 (Oxford/AstraZeneca) or CoronaVac (Sinovac/Butantan). Stratification of postvaccination AEs was performed using a diary, filled out daily and returned at the end of 28 days for each dose. Results A total of 188 patients with RA were include, 90% female. CoronaVac was used in 109 patients and ChAdOx1 in 79. Only mild AEs were observed, mainly after the first dose. The most common AEs after the first dose were pain at the injection (46,7%), headache (39,4%), arthralgia (39,4%), myalgia (30,5%) and fatigue (26,6%), and ChAdOx1 had a higher frequency of pain at the injection (66% vs 32 %, p < 0.001) arthralgia (62% vs 22%, p < 0.001) and myalgia (45% vs 20%, p < 0.001) compared to CoronaVac. The more common AEs after the second dose were pain at the injection (37%), arthralgia (31%), myalgia (23%), headache (21%) and fatigue (18%). Arthralgia (41,4% vs 25%, p = 0.02) and pain at injection (51,4% vs 27%, p = 0.001) were more common with ChAdOx1. No serious AEs were related. With Regard to RA activity level, no significant difference was observed between the three time periods for both COVID-19 vaccines. Conclusion In the comparison between the two immunizers in patients with RA, local reactions and musculoskeletal symptoms were more frequent with ChAdOx1 than with CoronaVac, especially after the first dose. In summary, the AE occurred mainly after the first dose, and were mild, like previous data from others immunizing agents in patients with rheumatoid arthritis.

Resumo Ogesso é um material largamente utilizado na construção civil, mas seu uso se restringe a áreas com pouca umidade ou ação da água. O estudo mostra a influência da aplicação de um aditivo hidrofugante comercial na produção de pastas de gesso. O ensaio de absorção de água por imersão total definiu os teores utilizados na caracterização das pastas no estado fresco e endurecido. A absorção de água diminuiu em 1,0% de adição e volta a crescer aos 2,0%, revelando que o teor ótimo do hidrofugante utilizado deve estar entre 0,3% e 1,0%. Na absorção de água por capilaridade, o aditivo apresentou melhor resultado quando utilizado em 1,0%, sendo a mistura classificada como preventiva à água. A resistência à compressão diminuiu em 3,6% e a dureza superficial em até 6,2% nas pastas, quando comparadas às de referência. O aditivo provocou a modificação das propriedades das pastas de gesso no estado fresco e endurecido. A formação da barreira impermeabilizante não foi verificada, e a utilização de maiores teores de hidrofugação poderá ser inviável devido ao elevado custo do aditivo. civil endurecido 10 1 0 1,0 20 2 2,0% 03 3 0,3 capilaridade 36 6 3,6 62 6,2 referência verificada 1, 2,0 0, 3, 6, 2,
Abstract Gypsum is a widely used material in civil construction, but its use is restricted to areas with low humidity or water action. The study shows the influence of the application of a commercial water-repellent additive in production of gypsum pastes. The total immersion water absorption test defined the contents used for the characterization of fresh and hardened plasters. The water absorption decreased in 1.0% and returned to increase in 2.0%, revealing that the optimal content of the water repellent used must be between 0.3% and 1.0% According to the capillary water absorption test, the water repellent additive showed the best results when used the content of 1.0% and was classified as water-preventive. The compressive strength decreased by 3.6% and the surface hardness by up to 6.2% in the pastes, when compared to the reference ones. The additive caused a change in the properties of gypsum pastes in the fresh and hardened state. The waterproofing barrier was not verified, the use of higher levels of water repellent may be unfeasible due to the high cost of the additive. construction action waterrepellent plasters 10 1 0 1.0 20 2 2.0% 03 3 0.3 waterpreventive. waterpreventive preventive. preventive water-preventive 36 6 3.6 62 6.2 ones state verified 1. 2.0 0. 3. 6. 2.

ABSTRACT The SISBIOTA-BRASIL was a three-year multimillion-dollar research program of the Brazilian government to document plants and animals in endangered/understudied areas and biomes in Brazil. Distributional patterns and the historical events that generated them are extensively unknown regarding Brazilian fauna and flora. This deficiency hinders the development of conservation policies and the understanding of evolutionary processes. Conservation decisions depend on precise knowledge of the taxonomy and geographic distribution of species. Given such a premise, we proposed to research the diversity of Diptera of the Brazilian western arc of Amazon, Cerrado, and Pantanal in the states of Mato Grosso, Mato Grosso do Sul, and Rondônia. Three important biomes of the South American continent characterize these Brazilian states: Amazon forest, Cerrado (Brazilian Savannah), and Pantanal. Besides their ecological relevance, these biomes historically lack intensive entomological surveys. Therefore, they are much underrepresented in the Brazilian natural history collections and in the scientific literature, which is further aggravated by the fact that these areas are being exponentially and rapidly converted to commercial lands. Our project involved over 90 collaborators from 24 different Brazilian institutions and one from Colombia among researchers, postdocs, graduate and undergraduate students, and technicians. We processed and analyzed nearly 300,000 specimens from ~60 families of Diptera collected with a large variety of methods in the sampled areas. Here, we provide a detailed overview of the genera and species diversity of 41 families treated. Our results point to a total of 2,130 species and 514 genera compiled and identified for the three states altogether, with an increase of 41% and 29% in the numbers of species and genera known for the three states combined, respectively. Overall, the 10 most species-rich families were Tachinidae, Cecidomyiidae, Tabanidae, Psychodidae, Sarcophagidae, Stratiomyidae, Bombyliidae, Syrphidae, Tephritidae, and Asilidae. The 10 most diverse in the number of genera were Tachinidae, Stratiomyidae, Asilidae, Mycetophilidae, Syrphidae, Tabanidae, Muscidae, Dolichopodidae, Sarcophagidae, and Chloropidae. So far, 111 scientific papers were published regarding taxonomic, phylogenetic, and biogeographical aspects of the studied families, with the description of 101 new species and three new genera. We expect that additional publications will result from this investigation because several specimens are now curated and being researched by specialists.

RESUMO OBJETIVO Estimar a soroprevalência de anticorpos do vírus SARS-CoV-2 em escolares de quatro a 14 anos de idade residentes no município de São Paulo, segundo variáveis clínicas, demográficas, epidemiológicas e sociais, durante o período de fechamento das escolas como medida de controle da covid-19. MÉTODOS Realizou-se um inquérito sorológico em setembro de 2020 com amostra aleatória estratificada por tipo de rede de ensino (pública municipal, pública estadual e privada). Foi coletada amostra de sangue venoso utilizando-se o teste de imunoensaio de fluxo lateral da fabricante Wondfo para detecção de anticorpos totais contra o vírus SARS-CoV-2. Aplicaram-se questionários semiestruturados para o levantamento de dados clínicos, demográficos, sociais e epidemiológicos. RESULTADOS A soroprevalência de anticorpos do vírus SARS-CoV-2 em escolares foi de 16,6% (IC95% 15,4–17,8). O estudo encontrou soroprevalências mais elevadas na rede pública municipal (18,5%; IC95% 16,6–20,6) e estadual (16,2%; IC95% 14,4–18,2) em relação à rede privada (11,7; IC95% 10,0–13,7) e entre escolares da raça/cor preta e parda (18,4%; IC95% 16,8–20,2) e no estrato social mais vulnerável (18,5%; IC95% 16,9–20,2). A pesquisa identificou menores soroprevalências nos escolares que relataram seguir as medidas recomendadas de proteção contra a covid-19. CONCLUSÃO A soroprevalência de anticorpos contra o vírus SARS-CoV-2 atinge principalmente os escolares socialmente mais vulneráveis. Este estudo pode contribuir para embasar políticas públicas que reforcem a importância da suspensão das aulas presenciais e da necessidade de estratégias de medidas de proteção e acompanhamento do status sorológico daqueles que ainda não foram contemplados no calendário vacinal.

ABSTRACT OBJECTIVE To estimate seroprevalence of SARS-CoV-2 antibodies in schoolchildren aged 4 to 14 years living in the city of São Paulo, according to clinical, demographic, epidemiological, and social variables, during the school closure period as a measure against covid-19 spread. METHODS A serological survey was made in September 2020 with a random sample stratified by school system (municipal public, state public and private) type. A venous blood sample was collected using the Wondfo SARS-CoV-2 Antibody Test (lateral flow method) for detection of total SARS-CoV-2 virus antibodies. Semi-structured questionnaires were applied to collect clinical, demographic, social, and epidemiological data. RESULTS Seroprevalence of SARS-CoV-2 antibodies in schoolchildren was of 16.6% (95%CI 15.4–17.8). The study found higher seroprevalence in the municipal (18.5%; 95%CI 16.6–20.6) and state (16.2%; 95%CI 14.4–18.2) public school systems compared to the private school system (11.7; 95%CI 10.0–13.7), among black and brown students (18.4%; 95%CI 16.8–20.2) and in the most vulnerable social stratum (18.5 %;95%CI 16.9–20.2). Lower seroprevalence was identified in schoolchildren who reported following the recommended protective measures against covid-19. CONCLUSION Seroprevalence of SARS-CoV-2 antibodies is found mainly in the most socially vulnerable schoolchildren. This study can contribute to support public policies that reinforce the importance of suspending face-to-face classes and developing strategies aimed at protective measures and monitoring of the serological status of those who have not yet been included in the vaccination schedule.

SUMMARY OBJECTIVE: This study aimed to determine the frequencies of Epstein-Barr virus, types 1 and 2 infection, and 30 bp del-latent membrane protein 1 viral polymorphism in gastric adenocarcinomas, as well as to investigate the association between Epstein-Barr virus infection and tumor location, type, and the patient's sex. METHODS: Samples were collected from 38 patients treated at a university hospital in Rio de Janeiro, Brazil. Epstein-Barr virus detection and genotyping were performed by polymerase chain reaction, followed by polyacrylamide gel electrophoresis and staining by the silver nitrate method. RESULTS: Overall, 68.4% of patients had Epstein-Barr virus-positive tumors. Of these, 65.4% presented infection by Epstein-Barr virus type 1, 23.1% by Epstein-Barr virus type 2, and 11.5% had coinfection with types 1 and 2. The 30 bp del-latent membrane protein 1 polymorphism was found in 42.3% of Epstein-Barr virus-positive tumors, 23.1% had the wild-type virus, and 23.1% had the wild-type and the polymorphism concomitantly. In 11.5% of Epstein-Barr virus-positive tumors, it was impossible to determine whether there was polymorphism or not. Tumor location in the antrum (22 of 38) and diffuse type (27 of 38) were predominant. There was no significant difference in Epstein-Barr virus infection or the 30 bp del-latent membrane protein 1 polymorphism between men and women.

Resumo O leiomiossarcoma de veia cava inferior (LVCI) é um raro tumor maligno mesenquimal. Seu tratamento cirúrgico é um desafio, pois necessita combinar margens cirúrgicas livres com reconstrução vascular, usando prótese ou enxerto autólogo, sutura primária ou ligadura simples sem reconstrução da veia. A ligadura é possível graças ao lento crescimento do tumor, permitindo o desenvolvimento de circulação venosa colateral. Apresentamos um caso de LVCI tratado por ressecção radical sem reconstrução vascular. Paciente feminina, 48 anos, com dor abdominal em hipocôndrio direito, astenia e sintomas dispépticos pós-prandiais. Tomografia de abdome revelou massa de formação expansiva localizada no segmento infra-hepático da veia cava inferior com redução da luz do vaso. Na cirurgia, o clampeamento da veia não indicou repercussões hemodinâmicas, sugerindo formação de circulação colateral suficiente. Decidiu-se pela ressecção radical em toda a porção da veia cava retro-hepática e ligadura da veia cava sem reconstrução vascular. A paciente evoluiu sem intercorrências.

Abstract Inferior vena cava leiomyosarcoma (IVCL) is a rare malignant mesenchymal tumor. Surgical treatment is a challenge because it must combine free surgical margins with vascular reconstruction, using prosthetic or autologous grafts, primary suture, or simple ligation without vein reconstruction. The ligation option is possible thanks to the slow growth of the tumor, allowing collateral venous circulation to develop. We present a case of an IVCL treated with radical resection without vascular reconstruction. The patient was a 48-year-old female with abdominal pain in the right upper quadrant, asthenia, and postprandial dyspeptic symptoms. Abdominal tomography revealed a mass with an expansive formation located in the infrahepatic segment of the inferior vena cava and reduced vessel lumen. During surgery, vein clamping did not provoke hemodynamic repercussions, suggesting sufficient collateral circulation formation. It was decided to perform a radical resection of the entire portion of the retrohepatic vena cava and ligate the vena cava without vascular reconstruction. The patient recovered without complications. (IVCL tumor reconstruction grafts suture develop 48yearold yearold 48 year old quadrant asthenia symptoms lumen surgery repercussions complications 4

BACKGROUND Leishmaniasis, a neglected disease caused by the parasite Leishmania, is treated with drugs associated with high toxicity and limited efficacy, in addition to constant reports of the emergence of resistant parasites. In this context, snake serums emerge as good candidates since they are natural sources with the potential to yield novel drugs. OBJECTIVES We aimed to show the antileishmanial effects of γCdcPLI, a phospholipase A2 inhibitor from Crotalus durissus collilineatus snake serum, against Leishmania (Leishmania) amazonensis. METHODS Promastigotes forms were exposed to γCdcPLI, and we assessed the parasite viability and cell cycle, as well as invasion and proliferation assays. FINDINGS Despite the low cytotoxicity effect on macrophages, our data indicate that γCdcPLI has a direct effect on parasites promoting an arrest in the G1 phase and reduction in the G2/M phase at the highest dose tested. Moreover, this PLA2 inhibitor reduced the parasite infectivity when promastigotes were pre-treated. Also, we demonstrated that the γCdcPLI treatment modulated the host cell environment impairing early and late steps of the parasitism. MAIN CONCLUSIONS γCdcPLI is an interesting tool for the discovery of new essential targets on the parasite, as well as an alternative compound to improve the effectiveness of the leishmaniasis treatment.
