Abstract Systemic Arterial Hypertension is a multifactorial clinical condition associated with severe outcomes such as stroke and death. One of the main modifiable risk factor for hypertension is an unhealthy diet, often characterized by the consumption of ultraprocessed foods such as sweetened beverages. We aimed to investigate the relationship between the consumption of sweetened beverages, both sugar-sweetened and artificially sweetened, and the prevalence of hypertension in adults. A cross-sectional, household, population-based study with 1,162 adults from two Brazilian cities were carried out. The consumption of food groups and sweetened beverages was obtained by food frequency questionnaire and other data were self-reported. Weight, height, and waist circumference were measured. The association between sweetened beverages consumption and hypertension was analyzed using Poisson regression models, expressed as Prevalence Ratio. The prevalence of hypertension was 16.7%, with no significant difference between genders. The prevalence of consumption of sweetened beverages was 70.3% in men and 54.6% in women, being significantly higher in men. Women who consumed sugar-sweetened and artificially sweetened beverages 6 to 7 days per week had 92% higher prevalence of hypertension compared to those who did not consume or consumed at a lower frequency. Furthermore, women who consumed artificially sweetened beverages at least 1 time per week had 3.36 times higher prevalence of hypertension. The habitual consumption of sweetened beverages may be an important risk factor for hypertension, especially the consumption of diet beverages, which are often marketed as healthier than sugar-sweetened beverages.

Resumen La Hipertensión Arterial Sistémica es una condición clínica multifactorial asociada a resultados graves como el ictus y la muerte. Uno de los principales factores de riesgo modificables de la hipertensión es una dieta poco saludable, a menudo caracterizada por el consumo de alimentos ultraprocesados como las bebidas endulzadas. Nuestro objetivo fue investigar la relación entre el consumo de bebidas endulzadas, tanto azucaradas como edulcoradas artificialmente, y la prevalencia de hipertensión en adultos. Se realizó un estudio transversal, domiciliario y poblacional con 1,162 adultos de dos ciudades brasileñas. El consumo de grupos de alimentos y bebidas endulzadas se obtuvo mediante cuestionario de frecuencia de alimentos y los demás datos fueron autoinformados. Se midieron el peso, la talla y el perímetro de la cintura. La asociación entre el consumo de bebidas endulzadas y la hipertensión se analizó mediante modelos de regresión de Poisson, expresados como Ratio de Prevalencia. La prevalencia de hipertensión fue del 16,7%, sin diferencias significativas entre géneros. La prevalencia de consumo de bebidas endulzadas fue del 70,3% en los hombres y del 54,6% en las mujeres, siendo significativamente mayor en los hombres. Las mujeres que consumían bebidas azucaradas y edulcoradas artificialmente entre 6 y 7 días a la semana tenían 92% mayor prevalencia de hipertensión que las que no consumían o consumían con una frecuencia menor. Además, las mujeres que consumían bebidas edulcoradas al menos 1 vez por semana tenían una prevalencia de hipertensión 3,36 veces mayor. Así pues, el consumo habitual de bebidas endulzadas puede ser un importante factor de riesgo de hipertensión, especialmente el consumo de bebidas dietéticas, que a menudo se comercializan como más saludables que las bebidas azucaradas.

Abstract Tityus serrulatus scorpion is responsible for a significant number of envenomings in Brazil, ranging from mild to severe, and in some cases, leading to fatalities. While supportive care is the primary treatment modality, moderate and severe cases require antivenom administration despite potential limitations and adverse effects. The remarkable proliferation of T. serrulatus scorpions, attributed to their biology and asexual reproduction, contributes to a high incidence of envenomation. T. serrulatus scorpion venom predominantly consists of short proteins acting as neurotoxins (α and β), that primarily target ion channels. Nevertheless, high molecular weight compounds, including metalloproteases, serine proteases, phospholipases, and hyaluronidases, are also present in the venom. These compounds play a crucial role in envenomation, influencing the severity of symptoms and the spread of venom. This review endeavors to comprehensively understand the T. serrulatus scorpion venom by elucidating the primary high molecular weight compounds and exploring their potential contributions to envenomation. Understanding these compounds' mechanisms of action can aid in developing more effective treatments and prevention strategies, ultimately mitigating the impact of scorpion envenomation on public health in Brazil.

Abstract We investigated the Biogran on bone repair and metabolism at several time-intervals upon grafting into rat tibia artificial defects. The biomaterial was thoroughly characterized in vitro, and its dissolution behavior upon immersion was assessed in simulated body fluid (SBF) solution for 1, 3, 7, 14, and 30 days. Biogran was also assessed by in vitro hydroxyapatite formation in SBF solution, which is a marker for bioactive behavior. In vivo, distal and proximal bone defects were performed in the Wistar rat's right tibia and filled according to the experimental groups: I) negative control, no filling; II) positive control, 10 mg of autogenous bone; and III) 10 mg of Biogran. Animals were euthanized at 1, 2, 3, 4, 7, and 10 weeks. Bone neoformation was analyzed using histomorphometry (proximal defect), and local levels of bone morphogenetic protein 2 (BMP-2) were measured using the ELISA assay (distal defect). In vitro, the Biogran sample showed a fast dissolution rate within the first 7 days, parallel to the formation of the hydroxyapatite layer. In vivo, the sample was progressively resorbed at a higher rate within the first month until it became almost absent at week 10th. The sample presented similar or higher bone neoformation concerning the autogenous bone. BMP-2 levels were sustained in the Biogran group (around 200 pg/mg) and detected until the last experimental time with a significant difference compared with the controls. Results suggest Biogran is a candidate for hard tissue engineering even in highly active bone remodeling sites.

Resumen La biogeografía histórica de los principales biomas de selvas de América del Sur ha intrigado a los científicos durante mucho tiempo. Los eventos paleoclimáticos durante los últimos 130 mil años promovieron conexiones entre biomas de selvas en la región neotropical, lo que llevó a distribuciones disjuntas de parte de la biota. En este contexto, el murciélago de MacConnell, Mesophylla macconnelli, parece ser un ejemplo de especie restringida al bosque con su distribución actual atravesada por las áreas secas de América del Sur. En este estudio, inferimos las conexiones pasadas entre la Amazonía y el Bosque Atlántico utilizando modelos de nicho ecológico y el murciélago de MacConnell. Obtuvimos 681 registros de la especie, y estimamos su distribución potencial durante el Último Interglacial (LIG), Último Máximo Glacial (LGM) y períodos actuales. Nuestros modelos generados, basados en 260 registros de ocurrencia filtrados, tuvieron muy buen poder predictivo, con valores de adherencia AUC y TSS superiores a 0.9. La estacionalidad de la temperatura y la precipitación anual tuvieron la mayor contribución relativa. La distribución potencial en el LIG sugiere una conexión de área adecuada entre el suroeste del Bosque Atlántico y el sur del Cerrado y la Amazonía. La distribución potencial en el LGM sugiere una expansión del rango hacia el norte y el este de la Amazonía. Las distribuciones actuales y pasadas inferidas de Mesophylla macconnelli sugieren al menos dos períodos de conexión pasada entre la Amazonía y el Bosque Atlántico. Este patrón se encuentra en otros vertebrados asociados a los bosques en América del Sur, lo que sugiere que los ciclos climáticos del Pleistoceno fueron fundamentales para la generación de distribuciones disjuntas en la región.

Abstract The historical biogeography of the major South American forested biomes has long intrigued scientists. Paleoclimatic events during the last 130 thousand years promoted connections between forested biomes in the Neotropical region, leading to disjunct distributions of some of the biota. In this context, MacConnell’s Bat, Mesophylla macconnelli, appears to represent a forest-restricted species with its current distribution bisected by dry areas. In this study, we infer past connections between the Amazonia and Atlantic Forest using MacConnell’s Bat and ecological niche models. We obtained 681 records of the species, and estimated its potential distribution during the Last Interglacial (LIG), Last Glacial Maximum (LGM), and current periods. Our generated models, based on 260 filtered occurrence records, had very good predictive power, with AUC and TSS adherence values above 0.9. Temperature seasonality and annual precipitation had the highest relative contribution. The potential distribution for the LIG suggested a suitable area connection between the southwestern Atlantic Forest and southern Cerrado and Amazonia. The potential distribution in the LGM suggests range expansion toward northern and eastern Amazonia. The current and inferred past distributions of Mesophylla macconnelli suggest at least two periods of past connection between Amazon and Atlantic Forest. This pattern is found in other forest-associated vertebrates in South America, suggesting that Pleistocene climatic cycles were central to the generation of disjunct distributions in the region.

Abstract This descriptive ecological study sought to analyze the inductive role of a federal financial incentive passed on to Brazilian municipalities in 2020, during the COVID-19 pandemic, in increasing the number of individual consultations for the condition of obesity in primary health care (PHC). Secondary data obtained from the Health Information System for Primary Care and from the Food and Nutrition Surveillance System (SISVAN) were used. In 2021, 74.8% of the 5,504 municipalities that received the financial incentive, showed an increase in the number of individual obesity consultations in PHC, compared to 2020. The number of people identified with obesity and the number of individual visits for this condition were higher in 2021 than in the other years analyzed (2017 to 2020). Comparing 2021 with 2020 (year of receipt of the financial incentive), it was observed that the percentage of increase in the number of individual consultations for the condition of obesity was higher than the increase in the number of people identified with obesity in the SISVAN (77.6 % vs. 39.1%). In conclusion, federal financial incentives for municipalities, channeled to enhance care for people with obesity within the scope of PHC, are important mechanisms for inducing actions at the local level.

Resumo O presente estudo ecológico descritivo objetivou analisar o papel indutor de um incentivo financeiro federal repassado aos municípios brasileiros em 2020, em meio à pandemia de COVID-19, no aumento do número de atendimentos individuais para a condição de obesidade na atenção primária à saúde (APS). Utilizaram-se dados secundários, obtidos no Sistema de Informação em Saúde para a Atenção Básica e no Sistema de Vigilância Alimentar e Nutricional (SISVAN). Em 2021, 74,8% dos 5.504 municípios que receberam o incentivo financeiro apresentaram aumento no número de atendimentos individuais para a condição avaliada como obesidade na APS, em relação a 2020. O número de pessoas identificadas com obesidade e o número de atendimentos individuais para esta condição foram maiores em 2021 do que nos demais anos analisados (2017 a 2020). Na comparação de 2021 com 2020 (ano de recebimento do incentivo financeiro), observou-se que o percentual de aumento de atendimentos individuais foi superior ao percentual de aumento de pessoas com obesidade registradas no SISVAN (77,6% vs. 39,1%). Em conclusão, incentivos financeiros federais, canalizados para o fortalecimento do cuidado às pessoas com obesidade no âmbito da APS, figuram como importantes mecanismos de indução de ações em nível local.

Abstract Objective: To describe the health-related quality of life (QOL) in children with cerebral palsy (CP) associated with congenital Zika infection. Methods: Cross-sectional study of a consecutive series of children, followed in a referral multicentric rehabilitation network in Brazil. We invited the caregivers to respond to the Brazilian version of the Caregiver Priorities & Child Health Index of Life with Disabilities (CPCHILDTM) questionnaire. Statistical analysis was performed with the Statistical Package for the Social Sciences (SPSS) 26.0™. We used absolute and relative frequencies for categorical variables and mean and standard deviation for continuous variables. Results: The sample consisted of 193 children, at mean age of 50.3±7.6 months. We observed a predominance of children with cerebral palsy (CP) with Gross Motor Function Classification System (GMFCS) level V (93.7%). Epilepsy (88.4%) was the most common comorbidity. CPCHILDTM mean scores were activities of daily living (ADL)/personal care 43.2±12.6; positioning, transferring and mobility 33.7±16.5; comfort and emotions 84.4±15.2; communication and social interaction (CoSI) 48.2±24.3; health 70.9±17.1; and overall quality of life (OQOL) 72.1±17.1. Total score was 54.8±11.3. Conclusions: Among children with cerebral palsy (CP) related to congenital Zika syndrome, the quality of life (QOL) scores were very similar to other populations with cerebral palsy (CP). The activities of positioning, transferring and mobility had the greatest impact on health-related quality of life (QOL). Rehabilitation strategies and public policies should prioritize aspects related to mobility for this population.

RESUMO Objetivo: Descrever a qualidade de vida relacionada à saúde em crianças com paralisia cerebral associada à infecção congênita pelo zika. Métodos: Estudo transversal de série consecutiva de casos de crianças acompanhadas em uma rede multicêntrica de reabilitação no Brasil. Convidamos o(s) cuidador(es) a responder à versão brasileira do Caregiver Priorities & Child Health Index of Life with Disabilities (CPCHILDTM). A análise estatística foi realizada com o pacote estatístico Statistical Package for the Social Sciences (SPSS) 26.0™. Para variáveis categóricas, foram utilizadas frequências absolutas e relativas e, para variáveis contínuas, média e desvio padrão. Resultados: Cento e noventa e três crianças, com idade média de 50,3±7,6 meses, foram incluídas. Observou-se predomínio de crianças com paralisia cerebral Gross Motor Function Classification System (GMFCS) nível V (93,7%). Epilepsia (88,4%) foi a comorbidade mais comum. As pontuações médias do CPCHILDTM foram: atividades de vida diária/cuidados pessoais 43,2±12,6; posicionamento, transferência e mobilidade 33,7±16,5; conforto e emoções 84,4±15,2; comunicação e interação social 48,2±24,3; saúde 70,9±17,1; e qualidade de vida geral 72,1±17,1. A pontuação total foi 54,8±11,3. Conclusões: Entre as crianças com paralisia cerebral relacionada à síndrome do zika congênita, as atividades de posicionamento, transferência e mobilidade tiveram maior impacto na qualidade de vida relacionada à saúde, semelhantemente a outras etiologias de paralisia cerebral. As estratégias de reabilitação e as políticas públicas devem priorizar os aspectos relacionados à mobilidade dessa população.

Abstract Objective: Given the high proliferative activity of germinal matrix and its direct correlation with hypoxemia, it is necessary to investigate the possible molecular regulation pathways, to understand the existing clinical relationship between the hypoxic-ischemic insult and the biomarkers NF-kB, AKT-3, Parkin, TRK-C and VEGFR-1. Methods: A hundred and eighteen germinal matrix samples of the central nervous system of patients who died in the first 28 days of life were submitted to histological and immunohistochemistry analysis to identify the tissue immunoexpression of those biomarkers related to asphyxia, prematurity, and death events within 24h. Results: A significantly increased tissue immunoexpression of NF-kB, AKT-3 and Parkin was observed in the germinal matrix of preterm infants. In addition, significantly decreased tissue immunoexpression of VEGFR-1 and NF-kB was observed in patients who experienced asphyxia followed by death within 24 hours. Conclusions: The results suggest a direct involvement between the hypoxic-ischemic insult and NF-kB and VEGFR-1 markers since a decreased immunoexpression of these biomarkers was observed in asphyxiated patients. Furthermore, it is suggested that there was not enough time for VEGFR-1 to be transcribed, translated and expressed on the surface of the plasma membrane. This temporality can be observed in the relationship between NF-kB expression and the survival time of individuals who died within 24 hours, suggesting that this factor is essential for the production of VEGFR-1 and, therefore, to carry out the necessary remodeling effect to neovascularize the affected region.

RESUMO Objetivo: Dada a alta atividade proliferativa da matriz germinativa e sua correlação direta com a hipoxemia, é necessário investigar as possíveis vias de regulação molecular para entender a relação clínica existente entre o insulto hipóxico-isquêmico e os biomarcadores NF-kB, AKT -3, Parkina, TRK-C e VEGFR-1. Métodos: Cento e dezoito amostras de matriz germinativa do sistema nervoso central de pacientes que faleceram nos primeiros 28 dias de vida foram submetidas a análise histológica e imuno-histoquímica para identificar a imunoexpressão tecidual desses biomarcadores relacionados a eventos de asfixia, prematuridade e óbito em 24 horas. Resultados: Observou-se uma imunoexpressão tecidual significativamente aumentada de NF-kB, AKT-3 e Parkin na matriz germinativa de prematuros. Além disso, constatou-se uma imunoexpressão tecidual significativamente diminuída de VEGFR-1 e de NF-kB em pacientes que apresentaram asfixia seguida de morte em 24 horas. Conclusões: Os resultados sugerem o envolvimento direto entre o insulto hipóxico-isquêmico e os marcadores NF-kB e VEGFR-1, visto que se observou uma imunoexpressão diminuída destes biomarcadores nos pacientes asfixiados. Além disso, sugere-se que não houve tempo suficiente para que o VEGFR-1 fosse transcrito, traduzido e expresso na superfície da membrana plasmática. Essa temporalidade pode ser observada na relação entre a expressão de NF-kB e o tempo de vida dos indivíduos que morreram em 24 horas, o que sugere que esse fator é essencial para a produção do VEGFR-1 e, portanto, para realizar o efeito remodelador necessário para neovascularizar a região afetada.

Abstract The canine filarial parasite Dirofilaria immitis has not been reported in Brazil´s Amazonas state capital, Manaus, for over a century. Here, we report one imported and 27 autochthonous D. immitis infections from a microfilarial survey of 766 domestic dog blood samples collected between 2017 and 2021 in Manaus. An Overall prevalence estimate of 15.44% (23/149) was calculated from our two rural collection sites; a prevalence of 1.22% (4/328) was estimated at our periurban collection site, and an overall prevalence of 0.35% (1/289) was calculated from our two urban clinic collections. Our data suggest that in the urban areas of Manaus, where the parasites are very likely vectored by the same species of mosquito that historically vectored Wuchereria bancrofti (Culex quinquefasciatus), prevalence levels are very low and possibly maintained by an influx from rural areas where sylvatic reservoirs and/or more favorable vector transmission dynamics maintain high prevalences.

Resumo O parasita filarial canino, Dirofilaria immitis, causa doença zoonótica, mas não tem sido registrado em Manaus, capital do estado do Amazonas, há mais de um século. Neste trabalho, foi relatado uma infecção por D. immitis alóctone e 27 autóctones de um levantamento de microfilárias em 766 amostras de sangue em cães domésticos, coletados entre 2017 e 2021 em Manaus. A prevalência de 15,44% (23/149) foi estabelecida em áreas rurais, 1,22% (4/328) para áreas periurbanas e de 0,35% (1/289) para duas clínicas veterinárias localizadas na zona urbana da cidade. Estes dados sugerem, portanto, que nas áreas urbanas de Manaus, nas quais o parasita é provavelmente vetorizado pela mesma espécie de mosquito que, historicamente, transmitiu Wuchereria bancrofti (Culex quinquefasciatus). Também os níveis de prevalência são baixos e, possivelmente, mantidos por um influxo de áreas rurais onde reservatórios silvestres e/ou dinâmicas de transmissão vetorial mais favoráveis mantêm uma prevalência mais elevada.

ABSTRACT Purpose: Acute mesenteric ischemia (AMI) is a condition in pediatric surgery that ranges from intestine necrosis to death. Ischemic postconditioning (IPoC) methods were developed to reduce the damage caused by revascularization. This study aimed to evaluate the efficacy of these methods in an experimental weaning rat model. Methods: Thirty-two 21-day-old Wistar rats were allocated into four groups according to the surgical procedure performed: control, ischemia-reperfusion injury (IRI), local (LIPoC) and remote IPoC (RIPoC). At euthanasia, fragments of the intestine, liver, lungs, and kidneys were submitted to histological, histomorphometric, and molecular analyses. Results: In the duodenum, intestines, and kidneys histological alterations promoted by IRI were reversed by remote postconditioning method. In the distal ileum, the histomorphometric alterations could be reversed by the postconditioning methods with more evident effects promoted by the remote method. The molecular analysis found that the levels of expression of Bax (proapoptotic) and Bcl-XL (antiapoptotic) genes in the intestine were increased by IRI. These alterations were equally reversed by the postconditioning methods, with more evident effects of the remote method. Conclusions: IPoC methods positively reduced the damage caused by IRI in weaning rats.

Abstract Objective To determine the association between nutritional status according to different cutoff points for body mass index (BMI) and the occurrence of noncommunicable chronic diseases (NCD) in older people. Methods A cross-sectional study of 365 older people was conducted using a questionnaire collecting information on health variables, body weight and height measurements. The association between classification of nutritional status using BMI and occurrence of NCD was estimated by the Odds Ratio (OR) and 95% Confidence Intervals (95%CI). Results As measured by the different BMI classification criteria, nutritional status varied: for normal weight (24.9-32.3%), excess weight (57.3-73.2%) and for underweight (1.9-15.3%). According to the Lipschitz classification, underweight was associated with lower occurrence of osteoarticular diseases (OR=0.38; 95%CI: 0.15-0.93) and cardiometabolic diseases (OR=0.42; 95%CI: 0.19- 0.94); while overweight was associated with higher occurrence of cardiometabolic diseases (OR=2.26; 95%CI: 1.30-3.93). According to the World Health Organization criteria, underweight was associated with lower occurrence of cardiometabolic diseases (OR=0.09; 95%CI: 0.01-0.61), overweight with lower occurrence of neuropsychological diseases (OR=0. 47; 95%CI: 0.26-0.87), while obese status was associated with higher occurrence of osteoarticular (OR=1.95; 95%CI: 1.08-3.52) and cardiometabolic (OR=3.02; 95%CI: 1.54-5.93) diseases. According to the Pan American Health Organization criteria, underweight was associated with lower occurrence of cardiometabolic diseases (OR=0.45; 95%CI: 0.22-0.91) and obese status with higher occurrence of osteoarticular (OR=1, 91; 95%CI: 1.16-3.15), cardiometabolic (OR=2.58; 95%CI: 1.36-4.85) and respiratory (OR=1.96; 95%CI: 1.16-3.16) diseases. Conclusion The classification criteria for BMI were negatively (underweight) and positively (excess weight) associated with the occurrence of NCD, exhibiting a stronger association when the overweight classification was differentiated from the obese classification.

Resumo Objetivo Verificar a associação entre estado nutricional segundo diferentes pontos de corte para índice de massa corporal (IMC) e ocorrência de doenças crônicas não transmissíveis (DCNT) em idosos. Métodos Estudo transversal, realizado com 365 idosos de ambos os sexos, utilizando-se um questionário contendo variáveis sobre saúde e medidas de peso e estatura. A associação entre classificação do estado nutricional pelo IMC e ocorrência de DCNT foi estimada pelo Odds Ratio (OR) e Intervalos de 95% de Confiança (IC95%). Resultados A partir dos critérios de classificação do IMC, o estado nutricional variou entre: adequado (24,9%-32,3%), excesso de peso (57,3%-73,2%) e baixo peso (1,9%-15,3%). Segundo a classificação do estado nutricional por Lipschitz, o baixo peso se associou à menor ocorrência de doenças osteoarticulares (OR=0,38; IC95%:0,15-0,93) e cardiometabólicas (OR=0,42; IC95%:0,19-0,94); o sobrepeso se associou à maior ocorrência de doenças cardiometabólicas (OR=2,26; IC95%:1,30-3,93). Segundo critérios da Organização Mundial de Saúde, o baixo peso se associou à menor ocorrência de doenças cardiometabólicas (OR=0,09; IC95%:0,01-0,61), sobrepeso à menor ocorrência de doenças neuropsicológicas (OR=0,47; IC95%:0,26-0,87), obesidade à maior ocorrência de doenças osteoarticulares (OR=1,95; IC95%:1,08-3,52) e cardiometabólicas (OR=3,02; IC95%: 1,54-5,93). Pelos critérios da Organização Pan-Americana da Saúde, o baixo peso se associou à menor ocorrência de doenças cardiometabólicas (OR=0,45; IC95%:0,22-0,91), obesidade à maior ocorrência de doenças osteoarticulares (OR=1,91; IC95%:1,16-3,15), cardiometabólicas (OR=2,58; IC95%:1,36-4,85) e respiratórias (OR=1,96; IC95%:1,16-3,16). Conclusão Os critérios de classificação do IMC associaram-se negativamente (baixo peso) e positivamente (excesso de peso) à ocorrência de DCNT, verificando-se maior força na associação quando se diferenciou sobrepeso de obesidade.

BACKGROUND Leishmania RNA virus 1 (LRV1) is commonly found in South American Leishmania parasites belonging to the subgenus Viannia, whereas Leishmania RNA virus 2 (LRV2) was previously thought to be restricted to the Old-World pathogens of the subgenus Leishmania. OBJECTIVES In this study, we investigated the presence of LRV2 in strains of Leishmania (L.) infantum, the causative agent of visceral leishmaniasis (VL), originating from different hosts, clinical forms, and geographical regions. METHODS A total of seventy-one isolates were screened for LRV2 using semi-nested reverse transcription-polymerase chain reaction (RT-PCR) targeting the RNA-dependent RNA polymerase (RdRp) gene. FINDINGS We detected LRV2 in two L. infantum isolates (CUR268 and HP-EMO) from canine and human cases, respectively. MAIN CONCLUSIONS To the best of our knowledge, this is the first detection of LRV2 in the New World.

Abstract In view of the morphological similarity between gastrointestinal stromal tumors (GIST) and other sarcomas of the intestine of dogs, the aim was to carry out the histomorphological and immunohistochemical diagnosis of these tumors, associating breed, sex and age, location and tumor invasion. 217 cases were evaluated by histopathology and 36 diagnosed by immunohistochemistry were included (24 GIST and 12 other intestinal sarcomas). Mixed breed dogs were the most diagnosed with GIST, mainly elderly females (9.5±2.2 years); in the other intestinal sarcomas, crossbreeds and Dachshunds, males and females, were equally affected. The cecum was the most affected by GISTs, with tumor invasion of the intestinal layers in all cases. The small intestine was the most affected by the other intestinal sarcomas, with invasion of the layers in most of these tumors. GISTs expressed markers such as CD117 and DOG-1, unlike other intestinal sarcomas. GIST and other intestinal sarcomas denoted histomorphological and immunophenotypic characteristics similar to histopathology, justifying the association of immunohistochemistry for the definitive diagnosis.

Resumo Tendo em vista a semelhança morfológica entre tumores estromais gastrointestinais (GIST) e outros sarcomas do intestino de cães, objetivou-se realizar o diagnóstico histomorfológico e imunoistoquímico desses tumores, associando raça, sexo e idade, localização e invasão tumoral. Foram avaliados 217 casos por histopatologia e incluídos 36 diagnosticados por imuno-histoquímica (24 GIST e 12 outros sarcomas intestinais). Cães sem raça definida foram os mais diagnosticados com GIST, principalmente fêmeas idosas (9,5±2,2 anos); nos demais sarcomas intestinais, mestiços e Dachshunds, machos e fêmeas, foram igualmente acometidos. O ceco foi o mais acometido pelos GISTs, com invasão tumoral das camadas intestinais em todos os casos. O intestino delgado foi o mais acometido pelos demais sarcomas intestinais, com invasão das camadas na maioria desses tumores. GISTs expressaram marcadores como CD117 e DOG-1, ao contrário de outros sarcomas intestinais. O GIST e outros sarcomas intestinais denotaram características histomorfológicas e imunofenotípicas semelhantes à histopatologia, justificando a associação da imuno-histoquímica para o diagnóstico definitivo.

ABSTRACT: Physical Education was included in the National Textbook Plan (PNLD) in 2019, and the teacher's manual was the adopted book model. This article analyzes the insertion of Physical Education in this program and considers the context of textbooks in this curricular component and the alignment of teacher manuals with the neoliberal curricular policies that have invaded the field of Brazilian education in the recent decades. First, we present the context of Physical Education textbooks in Brazil, from gymnastics guides to textbooks, and to PNLD manuals, a moment in which school Physical Education obtains new relevance in the publishing market. Then, we conduct an analysis of the textbook collection with the highest number of copies sold in 2019 and 2020, named Corporal Practices, from the Editora Moderna publishing company, revealing how it can be seen as one of the signs of ongoing neoliberal curricular reforms. Finally, we sound an alarm regarding the emergence of a sense of school Physical Education shaped by the market and point out alternatives to teacher manuals in order to escape the current market-oriented logic.

RESUMEN: La Educación Física se incluyó en el Plan Nacional de Libros de Texto (PNLD) en 2019, y el manual del maestro fue el modelo de libro adoptado. Este artículo analiza la inserción de la Educación Física en este programa y considera el curso de los libros de texto en este componente curricular y la alineación de los manuales docentes con las políticas curriculares neoliberales que han invadido el campo de la educación brasileña en las últimas décadas. En primer lugar, presentamos el contexto de los libros de texto de Educación Física en Brasil, desde guías de gimnasia, pasando por libros de texto, hasta manuales del PNLD, un momento en el que la Educación Física escolar despierta una nueva relevancia en el mercado editorial. Luego, realizamos un análisis de la colección de libros de texto que tuvo el mayor número de ejemplares vendidos en 2019 y 2020, la colección Prácticas Corporales de Editora Moderna, revelando cómo se puede tomar como una de las señales de las reformas neoliberales en el currículo en curso. Finalmente, alertamos sobre el surgimiento de un sentido de Educación Física escolar conformado por el mercado y apuntamos alternativas a los manuales del profesor con el fin de escapar de la lógica actual del mercado.

RESUMO: A Educação Física foi inserida no Plano Nacional do Livro Didático (PNLD) em 2019, sendo o manual do professor o modelo de livro adotado. Este artigo analisa a inserção da Educação Física nesse programa e considera o contexto dos livros didáticos nesse componente curricular e o alinhamento dos manuais do professor com as políticas neoliberais de currículo que invadiram o campo da educação brasileira nas últimas décadas. Em um primeiro momento apresentamos o percurso dos livros didáticos de Educação Física no Brasil, desde os guias ginásticos, passando pelos livros didáticos, até os manuais do PNLD, momento em que a Educação Física escolar desperta nova relevância no mercado editorial. Em seguida, realizamos uma análise da coleção de manuais didáticos que obteve a maior quantidade de exemplares vendidos nos anos de 2019 e de 2020, a coleção Práticas Corporais, da Editora Moderna, revelando como ela pode se tomada como um dos indícios das reformas neoliberais de currículo em curso. Por fim, alertamos para a emergência de um sentido de Educação Física escolar moldado pelo mercado e apontamos alternativas para os manuais do professor de forma a escapar da lógica mercadológica vigente.

ABSTRACT The genus Entoloma includes species with agaricoid, secotioid and gasteroid basidiomes. In recent years, some studies have been conducted with this genus in the northeastern region of Brazil. In this context, the state of Bahia has only Entoloma serrulatum and E. cyathiforme. In order to contribute to the knowledge of this genus in the state, this work presents a new occurrence of Entoloma for the State of Bahia. The specimen was collected during an expedition in the Serra do Conduru State Park, in southern Bahia. After the morphological analyses, the species Entoloma wednae was identified. This is the first record of the species for the State, and the third record in the scientific literature.

RESUMO O gênero Entoloma, abriga espécies com basidiomas agaricoides, secotioides e gasteroides. Nos últimos anos, poucos estudos foram realizados com esse gênero na região nordeste do Brasil. Neste contexto, encontra-se o Estado da Bahia, que conta com apenas o registro de Entoloma serrulatum e E. cyathiforme. Com o objetivo de contribuir para o conhecimento deste gênero no Estado, este trabalho apresenta uma nova ocorrência de Entoloma para o Estado da Bahia. O espécime foi coletado numa expedição realizada no Parque estadual da Serra do Conduru, no sul da Bahia. Após a análise morfológica a espécie Entoloma wednae foi identificada. Esse é o primeiro registro da espécie para o Estado, e o terceiro registro da mesma para a literatura científica.
