Abstract Over the last three decades, stroke care has undergone significant transformations mainly driven by the introduction of reperfusion therapy and the organization of systems of care. Patients receiving treatment through a well-structured stroke service have a much higher chance of favorable outcomes, thereby decreasing both disability and mortality. In this article, we reviewed the scientific evidence for stroke reperfusion therapy, including thrombolysis and thrombectomy, and its implementation in the public health system in Brazil.

Resumo Nas últimas três décadas, o tratamento do AVC sofreu transformações significativas, impulsionadas principalmente pela introdução das terapias de reperfusão e pela organização dos serviços de AVC. Os pacientes que recebem tratamento em um serviço de AVC bem estruturado têm uma probabilidade muito maior de resultados favoráveis, diminuindo assim a incapacidade funcional e a mortalidade. Neste artigo, revisamos as evidências científicas para as terapias de reperfusão do AVC, incluindo trombólise e trombectomia e sua implementação no sistema público de saúde no Brasil.

A pandemia da COVID-19 favoreceu a tendência crescente de insegurança alimentar observada nos últimos anos, causando consequências na saúde mental, como o estresse. Nosso objetivo foi analisar a prevalência de insegurança alimentar domiciliar antes e durante a pandemia da COVID-19 e a sua associação com o estresse percebido. Analisamos dados de dois estudos de base populacional conduzidos em 2019 e 2020 a 2021 com adultos em Criciúma, Estado de Santa Catarina, Sul do Brasil. A insegurança alimentar e o estresse percebido foram avaliados usando a Escala Brasileira de Insegurança Alimentar e da Escala de Estresse Percebido. As covariáveis foram sexo, idade, raça, escolaridade, renda, situação profissional, estado civil, aglomeração domiciliar, excesso de peso e qualidade da dieta. Associações brutas e ajustadas entre insegurança alimentar e estresse percebido foram avaliadas usando a regressão de Poisson. Foram avaliados 1.683 indivíduos. A prevalência de insegurança alimentar foi de 25,8% em 2019, diminuindo para 21,6% em 2020. A prevalência de estresse percebido foi de aproximadamente 38% nos dois anos. Antes da pandemia, a insegurança alimentar aumentava a prevalência de estresse percebido em 29% (RP = 1,29; IC95%: 1,02; 1,63), mas nenhuma associação foi encontrada durante a pandemia da COVID-19. Identificamos uma prevalência preocupante de insegurança alimentar antes e depois da pandemia, no entanto, a insegurança alimentar e o estresse percebido foram associados apenas em 2019. Uma avaliação desses aspectos após a pandemia da COVID-19 é necessária para garantir direitos básicos de vida para todos.

La creciente tendencia a la inseguridad alimentaria observada en los últimos años se ha visto favorecida por la pandemia de COVID-19, provocando consecuencias en la salud mental, tales como el estrés. Nuestro objetivo fue analizar la prevalencia de inseguridad alimentaria en el hogar antes y durante la pandemia de COVID-19 y su asociación con el estrés percibido. Analizamos datos de dos estudios poblacionales realizados en 2019 y 2020-2021 con adultos en Criciúma, Santa Catarina, Sur de Brasil. La inseguridad alimentaria y el estrés percibido se evaluaron con la Escala Brasileña de Inseguridad Alimentaria y la Escala de Estrés Percibido. Las covariables fueron sexo, edad, color de piel, escolaridad, ingresos, situación laboral, estado civil, hacinamiento en el hogar, sobrepeso y calidad de la dieta. Las asociaciones crudas y ajustadas entre la inseguridad alimentaria y el estrés percibido se evaluaron mediante regresión de Poisson. Se evaluó a un total de 1.683 personas. La prevalencia de la inseguridad alimentaria fue del 25,8% en 2019, disminuyendo al 21,6% en 2020. La prevalencia del estrés percibido fue de alrededor del 38% en ambos años. Antes de la pandemia, la inseguridad alimentaria aumentaba la prevalencia del estrés percibido en un 29% (RP = 1,29; IC95%: 1,02; 1,63), pero no se encontró ninguna asociación con COVID-19. Encontramos una prevalencia preocupante de inseguridad alimentaria antes y después de la pandemia, aunque la inseguridad alimentaria y el estrés percibido solo se asociaron en 2019. Es necesaria una evaluación de estos aspectos después del COVID-19 para garantizar los derechos básicos vitales para todos.

The growing prevalence of food insecurity observed in the last years, has been favored by the COVID-19 pandemic, leading to mental health issues, such as stress. We aim to analyze the prevalence of household food insecurity before and during the COVID-19 pandemic and its association with perceived stress. We analyzed data from two population-based studies conducted in 2019 and 2020-2021 in the municipality of Criciúma, State of Santa Catarina, Southern Brazil. Food insecurity and perceived stress were assessed with the Brazilian Food Insecurity Scale and the Perceived Stress Scale. The covariables were sex, age, skin color, schooling level, income, job status, marital status, household crowding, overweight, and diet quality. Crude and adjusted associations between food insecurity and perceived stress were assessed using Poisson regression. A total of 1,683 adult individuals were assessed. Prevalence of food insecurity was 25.8% in 2019, decreasing to 21.6% in 2020. Prevalence of perceived stress was about 38% for both years. Before the pandemic, food insecurity increased the prevalence of perceived stress by 29% (PR = 1.29; 95%CI: 1.02; 1.63), but no association was found during COVID-19. We found a worrying prevalence of food insecurity before and after de pandemic, nonetheless food insecurity and perceived stress were associated only in 2019. An assessment of these aspects after COVID-19 is needed to ensure basic life rights for all.

ABSTRACT The expression ‘you need to know to conserve’ is a well-known cliche among biologists. Documenting the richness of a group of organisms is the first step towards understanding biodiversity and preparing efficient conservation plans. In this context, many efforts have been made to quantify the number of species on Earth and estimate the number of species still unknown to science. A few countries have complete and integrated databases estimating the approximate number of species recorded for their territory, particularly in the Global South. In Brazil, a country of continental dimensions, revealing the richness of the second most diverse clade of invertebrates (=Mollusca) has been a goal of taxonomists. Recently, in an unprecedented, collective, and integrated effort among Brazilian malacologists, it was possible to estimate how many valid species of molluscs are there in Brazil. In this effort, more than 30 mollusc experts joined together to update the Taxonomic Catalogue of the Brazilian Fauna (TCBF), a governmental website that allows a quick and real-time updating of all Metazoan. So far, more than 5,000 updates have been made in TCBF, indicating the presence of 3,552 valid species of molluscs in Brazil, distributed among the main clades as follows: Caudofoveata (10 spp.), Solenogastres (6 spp.), Polyplacophora (35 spp.), Scaphopoda (43 spp.), Cephalopoda (92 spp.), Bivalvia (629 spp.) and Gastropoda (2,737 spp.). The present study, in addition to demonstrating for the first time the richness of Brazilian molluscs, also presents the state of the art of this important phylum of invertebrates highlighting its most representative and neglected groups.

ABSTRACT The scientific literature consistently points out that groups historically targeted by social stigma experience deleterious effects in different spheres of life. Despite its gravity and pervasiveness, there are still gaps in the investigation of the topic, such as that focused on the Courtesy Stigma, which is experienced by people who have affective or professional ties with the stigmatized individual. This article aimed to present the state of the art on Courtesy Stigma through a systematic review of original empirical studies published in peer-reviewed journals and indexed in the main databases related to the research field (PsycNET (APA), Pubmed, Bvs Brasil, CAPES, SciELO, and Pepsic journals). As keywords for the search for abstracts, we used: courtesy stigma, affiliate stigma and associative stigma. Altogether, 94 complete texts met the inclusion and exclusion criteria. Studies have shown that the Courtesy Stigma has been investigated predominantly among family members of people who have some type of problem related to their mental health, in addition to parents of children with some type of disability.

RESUMEN La literatura científica señala constantemente que los grupos históricamente afectados por el estigma social experimentan efectos nocivos en diferentes ámbitos de la vida. A pesar de su gravedad y omnipresencia, todavía hay vacíos en la investigación del tema, como el centrado en el estigma de cortesía, que experimentan las personas que tienen vínculos afectivos o profesionales con el individuo estigmatizado. Este artículo tuvo como objetivo presentar el estado del arte sobre el estigma de cortesía a través de una revisión sistemática de estudios empíricos originales publicados en revistas revisadas por pares e indexados en las principales bases de datos relacionadas con el campo de investigación (PsycNET (APA), Pubmed, Bvs Brasil, CAPES, SciELO y revistas Pepsic). Como palabras clave para la búsqueda de resúmenes, utilizamos: estigma de cortesía, estigma de afiliación y estigma de asociación. En total, 94 textos completos cumplieron con los criterios de inclusión y exclusión. Los estudios han demostrado que el estigma de cortesía se ha investigado principalmente entre miembros de la familia de personas que tienen algún tipo de problema relacionado con su salud mental, además de los padres de niños con algún tipo de discapacidad.

RESUMO A literatura científica aponta consistentemente que grupos historicamente alvos de estigma social experimentam efeitos deletérios, em diversas esferas da vida. A despeito da sua gravidade e pervasividade, ainda existem lacunas na investigação do tema, tais como aquela voltada para o Estigma de Cortesia, que é vivenciado por pessoas que possuem vínculos afetivos ou profissionais com o indivíduo estigmatizado. O presente artigo teve como objetivo apresentar o estado da arte sobre estigma de cortesia, por meio de uma revisão sistemática de estudos empíricos originais publicados em periódicos revisados por pares e indexados nas principais bases relacionadas ao campo de investigação (PsycNET (APA), Pubmed, Bvs Brasil, Periódicos CAPES, SciELO e Pepsic). Como palavras-chave, para a busca dos resumos, utilizou-se: estigma de cortesia, estigma de afiliação e estigma de associação. Ao todo, 94 textos completos atenderam aos critérios de inclusão e exclusão. Os estudos apontaram que o estigma de cortesia tem sido investigado predominantemente entre familiares de pessoas que possuem algum tipo de problema relacionado com sua saúde mental, além de pais de crianças com algum tipo de deficiência.

Abstract Introduction The deficiency of ADA2 (DADA2) is a rare autoinflammatory disease provoked by mutations in the ADA2 gene inherited in a recessive fashion. Up to this moment there is no consensus for the treatment of DADA2 and anti-TNF is the therapy of choice for chronic management whereas bone marrow transplantation is considered for refractory or severe phenotypes. Data from Brazil is scarce and this multicentric study reports 18 patients with DADA2 from Brazil. Patients and methods This is a multicentric study proposed by the Center for Rare and Immunological Disorders of the Hospital 9 de Julho - DASA, São Paulo - Brazil. Patients of any age with a confirmed diagnosis of DADA2 were eligible for this project and data on clinical, laboratory, genetics and treatment were collected. Results Eighteen patients from 10 different centers are reported here. All patients had disease onset at the pediatric age (median of 5 years) and most of them from the state of São Paulo. Vasculopathy with recurrent stroke was the most common phenotype but atypical phenotypes compatible with ALPS-like and Common Variable Immunodeficiency (CVID) was also found. All patients carried pathogenic mutations in the ADA2 gene. Acute management of vasculitis was not satisfactory with steroids in many patients and all those who used anti-TNF had favorable responses. Conclusion The low number of patients diagnosed with DADA2 in Brazil reinforces the need for disease awareness for this condition. Moreover, the absence of guidelines for diagnosis and management is also necessary (t).

ABSTRACT Cardiovascular disease is the main cause of death in patients with chronic kidney disease (CKD). Several heart conditions have been associated with CKD, including myocardial and pericardial diseases. This paper describes a case of Dialysis-related constrictive pericarditis in a patient diagnosed with sudden hypotension during a hemodialysis session. A 65-year-old man diagnosed with hypertension, diabetes, obesity, and cirrhosis on hemodialysis for two years complained of symptoms during one of his sessions described as malaise, lipothymia, and confusion. The patient had a record of poor compliance with the prescribed diet and missed dialysis sessions. He was sluggish during the physical examination, and presented hypophonetic heart sounds, a blood pressure of 50/30mmHg, and a prolonged capillary refill time. The patient was referred to the intensive care unit and was started on antibiotics and vasoactive drugs. His workup did not show signs of infection, while electrocardiography showed low QRS-wave voltage. His echocardiogram showed signs consistent with a thickened pericardium without pericardial effusion. Cardiac catheterization showed equalization of diastolic pressures in all heart chambers indicative of constrictive pericarditis. The patient underwent a pericardiectomy. Examination of surgical specimens indicated he had marked fibrosis and areas of dystrophic calcification without evidence of infection, consistent with Dialysis-related constrictive pericarditis. Hypotension for unknown causes must be considered in the differential diagnosis of dialysis patients.

RESUMO A doença cardiovascular é a principal causa de morte em pacientes com doença renal crônica (DRC). Várias formas de acometimento cardíaco têm sido associadas. à DRC, incluindo doenças miocárdicas e pericárdicas. Este artigo descreve um caso de pericardite constritiva relacionada a em um paciente diagnosticado com hipotensão súbita durante uma sessão de hemodiálise. Um homem de 65 anos com diagnósticos prévios de hipertensão, diabetes, obesidade e cirrose em hemodiálise por dois anos queixou-se de sintomas durante uma de suas sessões, descritos como mal-estar, lipotímia e confusão mental. Apresentava histórico de baixa adesão à dieta prescrita e faltas frequentes às sessões de diálise. Ele estava fraco durante o exame físico e apresentava bulhas cardíacas hipofonéticas, pressão arterial de 50/30mmHg e tempo de enchimento capilar prolongado. O paciente foi encaminhado para a unidade de terapia intensiva e iniciou o tratamento com antibióticos e drogas vasoativas. Investigação laboratorial não mostrou sinais de infecção, enquanto o eletrocardiograma mostrou baixa voltagem de complexo QRS. Seu ecocardiograma evidenciou sinais consistentes com um pericárdio espessado, sem derrame pericárdico. O cateterismo cardíaco mostrou equalização das pressões diastólicas em todas as câmaras cardíacas, indicativo de pericardite constritiva. O paciente foi submetido a uma pericardiectomia. O exame anatomopatológico mostrou sinais de acentuada fibrose acentuada fibrose e áreas de calcificação distrófica sem evidência de infecção, consistente com pericardite constritiva relacionada a por diálise. A hipotensão por causas desconhecidas deve ser considerada no diagnóstico diferencial de pacientes em diálise.

Resumo Objetivo: Avaliar joelhos de indivíduos com falência renal em hemodiálise por meio de ressonância magnética, em comparação com um grupo controle sem doença renal crônica. Materiais e Métodos: Estudo transversal, observacional, controlado, realizado entre agosto/2018 e fevereiro/2020. Os 15 casos consistiram de pacientes com cinco anos ou mais em hemodiálise, sem ruptura do tendão do quadríceps. Os 15 controles, sem doença renal crônica, foram pareados (1:1) por sexo, idade e nível de atividade física. Resultados: A média de idade dos casos foi 50 ± 15 anos e a dos controles, 49 ± 14 anos. A mediana do tempo em hemodiálise foi 11 anos (variação: 10-14 anos). Nos casos, os níveis séricos de paratormônio, ferritina, fosfatase alcalina, fósforo e creatinina estavam mais altos e os de albumina e hemoglobina, mais baixos (p < 0,05). Hipersinal no tendão foi demonstrado em 11 casos e três controles (p = 0,009). Derrame articular foi observado em nove casos e três controles (p < 0,05). A espessura, o comprimento e a largura do tendão não diferiram entre os grupos. Hipersinal no tendão do quadríceps não mostrou associação com o tempo em hemodiálise ou com os níveis de paratormônio intacto, hemoglobina e fosfatase alcalina. Conclusão: Pacientes em hemodiálise sem episódios de ruptura já apresentam hipersinal no tendão do quadríceps nas imagens de ressonância magnética.

Abstract Objective: To evaluate the knees of individuals with renal failure who are on hemodialysis, using magnetic resonance imaging (MRI), comparing them with those of a group of individuals with normal renal function. Materials and Methods: This was a cross-sectional, observational, controlled study conducted between August 2018 and February 2020. The cases consisted of 15 patients who had been on hemodialysis for ≥ 5 years and did not have a quadriceps tendon rupture. The controls consisted of 15 individuals with normal renal function who were matched (1:1) to the cases for sex, age, and physical activity level. The subjects in both groups underwent MRI of the right knee only. Results: The mean ages of the cases and controls were 50 ± 15 years and 49 ± 14 years, respectively. The median time on hemodialysis was 11 years (range, 10-14 years). Serum levels of parathyroid hormone, ferritin, alkaline phosphatase, phosphorus, and creatinine were higher among the cases than among the controls, whereas serum albumin and hemoglobin were lower (p < 0.05 for all). The MRI study showed a hyperintense signal in the quadriceps tendon in 11 of the cases and in three of the controls (p = 0.009). Knee joint effusion was observed in nine of the cases and in three of the controls (p < 0.05). The thickness, length, and width of the tendon did not differ between the groups. A hyperintense signal in the tendon was not associated with the time on hemodialysis; nor with the levels of intact parathyroid hormone, hemoglobin, or alkaline phosphatase. Conclusion: Patients on chronic hemodialysis, even those without a tendon rupture, show a hyperintense signal in the quadriceps tendon on MRI.

Abstract Background Acute ischemic stroke (AIS) is an extremely time-sensitive condition. The field triage of stroke patients should consider a careful balance between the best destination for the timely delivery of intravenous and/or endovascular reperfusion therapies. The Field Assessment Stroke Triage for Emergency Destination (FAST-ED) scale has been shown to have an accuracy comparable to that of the National Institutes of Health Stroke Scale (NIHSS). However, it has not been tested in the field. Objective To evaluate the accuracy of the FAST-ED scale in the detection of AIS due to large vessel occlusion (LVO) in the prehospital setting. Methods A cross-sectional study of consecutive prospective data collected from February 2017 to May 2019 in the city of Porto Alegre, state of Rio Grande do Sul, Southern Brazil, correlating the prehospital FAST-ED scale scores with the hospital diagnosis of LVO. Area under the curve (AUC), sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated. Results In total, 74 patients were included in the analysis. As compared with the diagnosis of LVO upon hospital discharge, the prehospital FAST-ED scale applied by paramedics had a sensitivity of 80%, a specificity of 47.7%, a PPV of 51.1%, an NPV of 77.8%, and an AUC of 0.68 (95% confidence interval [95%CI]: 0.55–0.80). Among the patients with a final diagnosis of AIS, the accuracy was higher, with an AUC of 0.75 (95%CI: 0.60–0.89), a sensitivity of 80%, a specificity of 60%, a PPV of 80%, and an NPV of 60%. Conclusions In the present study, the FAST-ED scale, which was applied by paramedics in the field, demonstrated moderate accuracy but high sensitivity and NPV, which are essential attributes for a triage scale. While larger studies are still needed, these findings further support the use of the FAST-ED in stroke triage.

Resumo Antecedentes O acidente vascular cerebral isquêmico (AVCI) é uma doença altamente dependente do tempo. A triagem de pacientes com AVCI na cena deve considerar um equilíbrio cuidadoso entre o melhor destino para a administração rápida de terapias de reperfusão intravenosas e/ou endovasculares.Jáfoi demonstrado que a escala deAvaliação de campo de triagem de AVC para destino de emergência (Field Assessment Stroke Triage for Emergency Destination, FAST-ED, em inglês) tem precisão comparável à da Escala de AVC dos Institutos Nacionais de Saúde dos Estados Unidos (National Institutes of Health Stroke Scale, NIHSS, em inglês). Entretanto, a FAST-ED não foi testada em campo. Objetivo Avaliar a acurácia da escala FAST-ED na detecção de AVCI por oclusão de grande vaso (OGV) no contexto pré-hospitalar. Métodos Estudo transversal de dados prospectivos consecutivos, coletados de fevereiro de 2017 a maio de 2019, em Porto Alegre, Rio Grande do Sul, Brasil, em que se correlacionam a pontuação pré-hospitalar na escala FAST-ED e o diagnóstico hospitalar de OGV. A área sob a curva (ASC), a sensibilidade, a especificidade, o valor preditivo positivo (VPP), e o valor preditivo negativo (VPN) foram calculados. Resultados Ao todo, 74 pacientes foram incluídosnaanálise. Comparada aodiagnóstico de OGV na alta hospitalar, a escala FAST-ED aplicada em campo por profissionais do préhospitalar teve sensibilidadede80%, especificidadede47,7%, VPPde51,1%, VPN de 77,8%, e ASC de 0,68 (intervalo de confiança de 95% [IC95%]: 0,55–0,80). Entre pacientes com diagnóstico final de AVCI, a precisão foi mais alta, com ASC de 0,75 (IC95%: 0,60–0,89), sensibilidade de 80%, especificidade de 60%, VPP de 80%, e VPN de 60%. Conclusões Neste estudo, a escala FAST-ED, aplicada por profissionais do pré-hospitalar em campo, demonstrou precisão moderada, com alta sensibilidade e VPN, atributos essenciaispara umaescaladetriagem.Embora estudoscomamostras maiores ainda sejam necessários, estes achados apoiam o uso da FAST-ED na triagem de AVCI.

Abstract This work aims to evaluate the application of ultrasound and marinate with extract of acerola (Malpighia emarginata) residue on the tenderness and lipid oxidation of the meat pork. Samples of loin (Longissimus dorsi) containing approximately 90 g, 10 cm long, 5 cm wide, and 2 cm high were extracted from the pig carcass. The samples were coded and randomly allocated under a factorial scheme 2 (with and without antioxidant extract) x 3 (ultrasonic bath times 0, 5, and 10 minutes); each treatment had four replicates. The final extract volume was adjusted with distilled water, ensuring 200 mg of gallic acid equivalents per kilo of meat. Then, the samples were placed in the ultrasonic bath at a fixed frequency of 170 W, 35 kHz. During the ultrasound application, the bath temperature was maintained at 10 °C with ice/ice water addition when necessary. The acerola´s extract showed a significant effect (P < 0.05) on the meat Cohesiveness and to a lesser extent before rupture. With the modification of the microstructure in the meat, there was a decrease in elasticity. The application of ultrasound to meat (170 W, 35 kHz) in times (5 and 10 minutes) combined with the marinating in a natural antioxidant acerolas residue extract improves the meat's quality characteristics, decreasing the hardness and chewiness.

Abstract This study's objective was to evaluate the physical-chemical, microbiological, and sensory aspects of pork meat with different levels of salting. Pork from the Duroc and Landrace breeds, with an average live weight of 281 ± 15.72 kg, were used. The physicochemical data were analyzed following a completely randomized design with four salt addition levels (30, 50, 70, and 90%). Sensory analysis was performed through a completely randomized design, observing the influence of salt levels in meat. The physical-chemical and sensory variables did not significantly affect (P>0.05) salt addition, except for cooking loss and water retention capacity. It was concluded that the salt introduction levels of 30 and 50% are the most appreciated by consumers. The addition of salt levels in the pork meat does not modify the physical-chemical characteristics and the meat's sensory analysis.

RESUMO As rupturas do tendão do quadríceps são lesões incomuns, frequentemente associadas a doenças crônicas, incluindo a doença renal em estágio de falência funcional. O papel do hiperparatireoidismo secundário como fator predisponente para rupturas tendinosas nesse grupo de pacientes está bem documentado, e o enfraquecimento da junção tendão-osso faz parte desse contexto. O tratamento de escolha para rupturas do tendão do quadríceps em pacientes com falência renal é a cirurgia, e deve ser realizado o mais rápido possível. Existem várias técnicas cirúrgicas a serem utilizadas, mas a falta de estudos comparativos não nos permite concluir qual é a melhor opção. Publicações mais recentes têm preferido a associação de técnicas, com destaque para o uso de enxerto tendíneo autólogo como ferramenta de reforço, procedimento de escolha do autor. Estudos recentes relatam o uso de agentes biológicos para estimular a cicatrização e aloenxertos, mas as informações parecem preliminares para serem rotineiramente recomendadas. Nível de Evidência II; Observação de estudos terapêuticos.

ABSTRACT Quadriceps tendon tears are uncommon injuries often associated with chronic diseases, including end-stage renal disease (ESRD). The role of secondary hyperparathyroidism as a predisposing factor for tendon tears in this group of patients is well documented, and the weakening of the tendon-bone junction is part of this context. The treatment of choice for quadriceps tendon ruptures in patients with ESRD is surgery, which should be performed as soon as possible. There are several surgical techniques to be used, but the lack of comparative studies does not allow us to conclude which one is the best option. More recent publications have preferred the association of techniques, with emphasis on the use of autologous tendon grafts as a reinforcement tool, which is the author’s procedure of choice. Recent studies reported the use of biological agents to stimulate healing and allografts, but the information seems preliminary to be routinely recommended. Level of evidence II; Obsevation of therapeutic studies.

Resumo O trombo mural aórtico primário é definido como um trombo aderido à parede aórtica na ausência de doença aterosclerótica e/ou aneurismática ou de fonte cardíaca de êmbolo. Trata-se de uma doença rara, porém causadora de alta morbimortalidade, e não há consenso acerca do seu tratamento. Este estudo objetivou revisar as possibilidades na presença de componente móvel. A terapia endovascular e a cirurgia aberta parecem ser as melhores opções, sendo a abordagem endovascular o tratamento de escolha para pacientes com anatomia favorável e a cirurgia aberta o tratamento de escolha para pacientes com anatomia desfavorável. No entanto, a anticoagulação sistêmica apresenta-se como método não invasivo para pacientes com alto risco cirúrgico e como possibilidade terapêutica na falha ou indisponibilidade de abordagem cirúrgica.

Abstract A primary aortic mural thrombus (PAMT) is defined as a thrombus attached to the aortic wall in the absence of any atherosclerotic or aneurysmal disease of the aorta or any cardiac source of embolus. It is a rare entity that has high morbidity and mortality. There is no consensus on the ideal treatment of PAMT. The objective of this paper is to review the possibilities for treatment of mobile abdominal aortic mural thrombus. Endovascular therapy and open surgery appear to be the best options for treatment of mobile abdominal aortic mural thrombus. Thus, in patients with favorable anatomy, endovascular therapy is probably the treatment choice, while in those with unfavorable anatomy, open surgery is probably the best option for treatment of a mobile abdominal aortic thrombus. It is important to emphasize that anticoagulation alone can be used as a non-aggressive option and, if this fails, endovascular or surgical methods can then be employed.

Resumo A evolução biológica é frequentemente considerada um eixo central e unificador da biologia. O artigo discute aspectos históricos desse ideal de unificação, bem como os seus sinais de desintegração entre os anos 1960 e 1980. Argumentamos que apesar das novas propostas de síntese do conhecimento biológico, a biologia evolutiva contemporânea é caracterizada por um pluralismo. Os principais pontos a favor do pluralismo evolutivo são discutidos, e algumas consequências dessa perspectiva são apresentadas, particularmente em relação ao ideal de unificação da biologia. Por fim, defendemos um pluralismo evolutivo crítico do ideal de unificação como um objetivo da ciência, mas ainda favorável a integrações locais.

Abstract Biological evolution is often regarded as a central and unifying axis of biology. This article discusses historical aspects of this ideal of unification, as well as signs of its disintegration from the 1960s to 1980s. We argue that despite new proposals for the synthesis of biological knowledge, contemporary evolutionary biology is characterized by pluralism. The main points in favor of evolutionary pluralism are discussed and some consequences of this perspective are presented, particularly in terms of the ideal of a unified biology. Finally, we defend an evolutionary pluralism that critiques the ideal of unification as a scientific objective, but still favors local integrations.
