Abstract It is repeatedly stressed the need to characterize the extant biodiversity in tropical ecosystems. However, inventory studies are still progressing slowly in dry ecosystems, leading to the underestimation of their true biodiversity and hindering conservation efforts. In this study, we present primary and secondary data, along with an updated list of amphibians and reptiles from two localities in the São Francisco-Gurguéia region in Piauí. Additionally, we compare the species composition between nine areas within the Caatinga, which were sampled using standardized methods over the past ten years, to examine broader spatial patterns of community composition. To survey reptiles and amphibians, we employed similar methods and sampling efforts in two areas within the Serra das Confusões National Park (SCNP) region. Our surveys recorded a total of 73 species of amphibians and reptiles, of which 24 are new distribution records for the SCNP region. Consequently, our findings increase the known herpetofauna in the region to 94 species. Despite their proximity, the two sites in the SCNP region exhibited only 42% similarity in species composition, and they differed significantly from other areas within the Caatinga. Furthermore, even the closer Caatinga areas presented differences in species composition, highlighting the necessity to evaluate biodiversity across the landscape and contribute to understanding biogeographic patterns. ecosystems However study data FranciscoGurguéia Francisco Gurguéia Piauí Additionally years (SCNP 7 2 Consequently 9 proximity 42 Furthermore 4

Resumo É repetidamente enfatizada a necessidade de caracterizar a biodiversidade vivente em ecossistemas tropicais. No entanto, os estudos de inventário ainda estão progredindo lentamente em ecossistemas secos, levando à subestimação de sua verdadeira biodiversidade e dificultando os esforços de conservação. Neste estudo, apresentamos dados primários e secundários, juntamente com uma lista atualizada de anfíbios e répteis de duas localidades na região de São Francisco-Gurguéia, do Piauí. Além disso, comparamos a composição de espécies entre nove áreas dentro da Caatinga, que foram amostradas usando métodos padronizados nos últimos dez anos, para examinar padrões espaciais mais amplos de composição da comunidade. Para estudar répteis e anfíbios, utilizamos métodos e esforços de amostragem semelhantes em duas áreas na região do Parque Nacional da Serra das Confusões (PNSC). Nossos levantamentos registraram um total de 73 espécies de anfíbios e répteis, das quais 24 são novos registros de distribuição para a região do PNSC. Consequentemente, nossos resultados aumentam a herpetofauna conhecida na região para 94 espécies. Apesar da proximidade, os dois locais na região do PNSC exibiram apenas 42% de similaridade na composição de espécies e diferiram significativamente de outras áreas dentro da Caatinga. Mesmo áreas mais próximas da Caatinga apresentaram diferenças na composição de espécies, destacando a necessidade de avaliar a biodiversidade em toda a paisagem e contribuir para a compreensão de padrões biogeográficos. tropicais entanto secos conservação estudo secundários FranciscoGurguéia, FranciscoGurguéia Francisco Gurguéia, Gurguéia Francisco-Gurguéia Piauí disso anos comunidade .

Abstract Choosing a surgical specialty can be a hard decision for a medical student. Several studies present data showing that most medical students fear the surgical field and end up switching to another specialty. For cardiovascular surgery, the scenario is very similar. In the last decades, the interest in cardiovascular surgery has been decreasing worldwide and the cardiothoracic surgical societies across the globe have been trying to understand the factors that push away medical students and general surgical residents from the specialty. In this regard, our work aims to focus on describe the access of students to cardiovascular surgery, especially during medical school, as well as to provide a brief report of our current data regarding the specialty. student similar decades regard school

Resumo Apresentamos o primeiro inventário detalhado da fauna de lagartos da região do Alto Sertão sergipano, nordeste do Brasil, a partir de três expedições de campo realizadas pelos autores e exemplares depositados na Coleção Herpetológica da Universidade Federal de Sergipe. Os três inventários foram realizados entre 2010 e 2016, nos municípios de Canindé de São Francisco, Poço Redondo, Monte Alegre de Sergipe, Nossa Senhora da Glória e Porto da Folha. No total, foram amostrados 9.487 lagartos de 19 espécies (10 famílias), das quais 10 são novos registros para a área de estudo. As espécies mais abundantes foram Ameivula ocellifera, Tropidurus hispidus e T. semitaeniatus. Treze espécies foram consideradas com ampla distribuição na Caatinga, cinco apresentaram distribuição relictual e uma exótica. Sugerimos que futuras pesquisas se concentrem principalmente em áreas não amostradas e priorizem os municípios de Gararu, Nossa Senhora da Glória e Nossa Senhora de Lourdes por se tratarem de localidades com pouca ou nenhuma amostragem.

Abstract We present the first detailed inventory of the lizard fauna of Alto Sertão region, west of Sergipe state, based on three field expeditions carried out by the authors and specimens deposited at the Herpetological Collection of Universidade Federal de Sergipe. The three inventories were carried out between 2010 and 2016, in the municipalities of Canindé de São Francisco, Poço Redondo, Monte Alegre de Sergipe, Nossa Senhora da Glória, and Porto da Folha. In total, we sampled 9,485 lizards of 19 species (10 families) of which 10 are new records for the study area. The most abundant species were Ameivula ocellifera, Tropidurus hispidus and T. semitaeniatus. Thirteen species were considered as widely distributed in Caatinga, five presented a relictual distribution and one was exotic. We suggest that future research focus mainly on non-sampled areas and should prioritize the municipalities of Gararu, Nossa Senhora da Glória and Nossa Senhora de Lourdes since they are localities with little or no sampling records.

Abstract Introduction: Coronary artery bypass grafting (CABG) is the most frequently performed heart surgery in Brazil. Recent international guidelines recommend that national societies establish a database on the practice and results of CABG. In anticipation of the recommendation, the BYPASS Registry was introduced in 2015. Objective: To analyze the profile, risk factors and outcomes of patients undergoing CABG in Brazil, as well as to examine the predominant surgical strategy, based on the data included in the BYPASS Registry. Methods: A cross-sectional study of 2292 patients undergoing CABG surgery and cataloged in the BYPASS Registry up to November 2018. Demographic data, clinical presentation, operative variables, and postoperative hospital outcomes were analyzed. Results: Patients referred to CABG in Brazil are predominantly male (71%), with prior myocardial infarction in 41.1% of cases, diabetes in 42.5%, and ejection fraction lower than 40% in 9.7%. The Heart Team indicated surgery in 32.9% of the cases. Most of the patients underwent cardiopulmonary bypass (87%), and cardioplegia was the strategy of myocardial protection chosen in 95.2% of the cases. The left internal thoracic artery was used as a graft in 91% of the cases; the right internal thoracic artery, in 5.6%; and the radial artery in 1.1%. The saphenous vein graft was used in 84.1% of the patients, being the only graft employed in 7.7% of the patients. The median number of coronary vessels treated was 3. Operative mortality was 2.8%, and the incidence of cerebrovascular accident was 1.2%. Conclusion: CABG data in Brazil provided by the BYPASS Registry analysis are representative of our national reality and practice. This database constitutes an important reference for indications and comparisons of therapeutic procedures, as well as to propose subsequent models to improve patient safety and the quality of surgical practice in the country.

Abstract Introduction: Although it only corresponds to 2.5% of congenital heart defects, hypoplastic left heart syndrome (HLHS) is responsible for more than 25% of cardiac deaths in the first week of life. Palliative surgery performed after the second week of life is considered an important risk factor in the treatment of HLHS. Objective: The aim of this study is to describe the initial experience of a medical center in Northeastern Brazil with a modified off-pump hybrid approach for palliation of HLHS. Methods: From November 2012 through November 2015, the medical records of 8 patients with HLHS undergoing hybrid procedure were retrospectively evaluated in a tertiary private hospital in Northeastern Brazil. The modified off-pump hybrid palliation consisted of stenting of the ductus arteriosus guided by fluoroscopy without contrast and banding of the main pulmonary artery branches. Demographic and clinical variables were recorded for descriptive analysis. Results: Eight patients were included in this study, of whom 37.5% were female. The median age and weight at the time of the procedure was 2 days (p25% and p75% = 2 and 4.5 days, respectively) and 3150 g (p25% and p75% = 3077.5 g and 3400 g, respectively), respectively. The median length in intensive care unit stay was 6 days (p25% and p75% = 3.5% and 8 days, respectively). There were no in-hospital deaths. Four patients have undergone to the second stage of the surgical treatment of HLHS. Conclusion: In this series, the initial experience with the modified off-pump hybrid procedure showed to be safe, allowing a low early mortality rate among children presenting HLHS.

Abstract Objective: To report the early results of the BYPASS project - the Brazilian registrY of adult Patient undergoing cArdiovaScular Surgery - a national, observational, prospective, and longitudinal follow-up registry, aiming to chart a profile of patients undergoing cardiovascular surgery in Brazil, assessing the data harvested from the initial 1,722 patients. Methods: Data collection involved institutions throughout the whole country, comprising 17 centers in 4 regions: Southeast (8), Northeast (5), South (3), and Center-West (1). The study population consists of patients over 18 years of age, and the types of operations recorded were: coronary artery bypass graft (CABG), mitral valve, aortic valve (either conventional or transcatheter), surgical correction of atrial fibrillation, cardiac transplantation, mechanical circulatory support and congenital heart diseases in adults. Results: 83.1% of patients came from the public health system (SUS), 9.6% from the supplemental (private insurance) healthcare systems; and 7.3% from private (out-of -pocket) clinic. Male patients comprised 66%, 30% were diabetics, 46% had dyslipidemia, 28% previously sustained a myocardial infarction, and 9.4% underwent prior cardiovascular surgery. Patients underwent coronary artery bypass surgery were 54.1% and 31.5% to valve surgery, either isolated or combined. The overall postoperative mortality up to the 7th postoperative day was 4%; for CABG was 2.6%, and for valve operations, 4.4%. Conclusion: This first report outlines the consecution of the Brazilian surgical cardiac database, intended to serve primarily as a tool for providing information for clinical improvement and patient safety and constitute a basis for production of research protocols.

Resumo Os aneurismas de aorta abdominal infecciosos (AAAIs) são raros e apresentam uma alta mortalidade devido à septicemia e ao risco de ruptura. A opção terapêutica consagrada consiste na correção aberta com ressecção do aneurisma, debridamento e reconstrução com veia autóloga. Mais recentemente, alguns grupos vêm relatando séries de casos nas quais se realizou tratamento endovascular. Em ambas as opções, a antibioticoterapia adjuvante é imperativa. Relatamos um caso ilustrativo em que o tratamento de escolha foi a cirurgia aberta com reconstrução utilizando-se veia autóloga.

Abstract Infected abdominal aortic aneurysms are rare and have high mortality due to sepsis and the possibility of rupture. The treatment of choice is open repair with aneurysm resection, debridement and reconstruction with an autologous vein graft. More recently, case series have been described in which the endovascular approach was the first option. With both approaches adjuvant antibiotic therapy is imperative. We report an illustrative case in which the treatment was open surgery reconstruction using an autologous vein graft.

En un ecotono de bosque atlántico y Caatinga, ubicado en el Parque Nacional Serra de Itabaiana, Sergipe, Brasil, fueron estudiadas las formas de uso de recursos espaciales y temporales de dos espécies simpátricas de Ameivula El estudio se realizó entre febrero de 2008 y enero de 2009. El método adoptado fue la búsqueda activa con control de tiempo, en el periodo de las 06:00-18:00 horas. Se observó que la especie con más registros fue A. ocellifera. A pesar del alto solapamiento de nicho temporal observado (Ojk = 0,90), A. ocellifera y A. abaetensis difirieron en relación con los momentos de mayor actividad. A. ocellifera se observó con mayor frecuencia (≥ 10 %) 08:00-13:00, mientras que A. abaetensis de 09:00 a 13:00 horas. Ambas especies fueron más frecuentes en los días soleados, con patrones similares de actividad en el momento de la observación, fueron vistas por lo general caminando sobre la arena (A. ocellifera) o en las hojas cerca de la base de arbustos (A. abaetensis). Conductas adoptadas por las dos especies Ameivula en respuesta al enfoque del observador eran diferentes y estaban relacionados con el grado de exposición de la vulnerabilidad a la depredación. La coexistencia de A. ocellifera y A. abaetensis en el área de estudio se relaciona posiblemente con pequeñas diferencias en el patrón de tiempo de uso de los recursos y el espacio de las dos especies, estas diferencias son probablemente el resultado de las interacciones ecológicas actuales. Los resultados obtenidos en este estudio contribuyen a la comprensión de la historia natural y ecología de las especies de Ameivula y generan principalmente información útil para la conservación de estas especies en hábitats de transición de la Mata Atlántica-Caatinga.

The forms of spatial and temporal resources use of two sympatric species of Ameivula were studied in an Atlantic Forest-Caatinga ecotone located in Parque Nacional Serra de Itabaiana, Sergipe, Brazil. The study was conducted between February 2008 and January 2009. The method used was an active search for a limited time, from 06:00 am to 06:00 pm. The species were observed during all months sampled, and A. ocellifera presented the highest number of sightings. Despite the high temporal niche overlap observed (Ojk = 0.90), A. ocellifera and A. abaetensis differed regarding the times of higher activity. A. ocellifera was most seen (≥ 10%) between 08:00 am and 01:00 pm, and A. abaetensis from 09:00 am to 01:00 pm. Both species were found more frequently on sunny days, with similar patterns of activity at the time of sighting, being usually observed walking on sand (A. ocellifera) or leaves near the base of shrubs (A. abaetensis). The behaviors demonstrated by both species of Ameivula in response to the approach of the observer were different and were related to the level of exposure along with the vulnerability to predation. The coexistence of A. ocellifera and A. abaetensis in the study area is possibly related to minor differences in the use pattern of temporal and spatial resources by both species, and these differences are probably due to the current ecological interactions. The results obtained in this study contribute to the understanding of the natural history and ecology of the species of Ameivula and mainly generate useful information for the conservation of these species in habitats transitional of Atlantic Forest-Caatinga.

As formas de utilização dos recursos espaciais e temporais por duas espécies simpátricas de Ameivula foram estudadas em um ecótono de Mata Atlântica e Caatinga, situado no Parque Nacional Serra de Itabaiana, Sergipe, Brasil. O estudo foi desenvolvido entre fevereiro de 2008 e janeiro de 2009. O método adotado foi o de busca ativa limitado por tempo, sendo utilizado o período das 06:00 às 18:00 h. As duas espécies foram verificadas ao longo de todos os meses de coleta, sendo A. ocellifera a com maior número de registros. Apesar da alta sobreposição de nicho temporal observada (Ojk = 0,90), A. ocellifera e A. abaetensis diferiram em relação aos horários de maior atividade. A. ocellifera foi avistado com maiores frequências (≥10 %) entre 08:00 e 13:00 h, enquanto que A. abaetensis, entre as 09:00 às 13:00 h. As duas espécies foram mais frequentes em dias ensolarados, com padrões similares de atividade no momento do avistamento, tendo as mesmas sido verificadas, em geral, andando sobre areia (A. ocellifera) ou folhas próximas à base de arbustos (A. abaetensis). Os comportamentos adotados pelas duas espécies de Ameivula em resposta à aproximação do observador foram diferenciados e estiveram relacionados ao grau de exposição e, consequentemente, de vulnerabilidade à predação. A coexistência de A. ocellifera e A. abaetensis na área de estudo está possivelmente relacionada a pequenas divergências no padrão de uso de recursos temporais e espaciais pelas duas espécies, sendo provavelmente essas diferenças resultantes de interações ecológicas atuais. Os dados obtidos neste estudo contribuem para o conhecimento sobre a história natural e ecologia das espécies de Ameivula e, principalmente, geram informações úteis para a conservação destas espécies em hábitats de transição Mata Atlântica-Caatinga.

Apesar do crescente aumento nos inventários de herpetofauna no bioma Caatinga, ainda faltam informações para muitas áreas e novos estudos são necessários. O Parque Nacional do Catimbau, Pernambuco, Brasil, foi inventariado entre os meses de março e abril de 2013 totalizando 30 dias de amostragem, para descrever a herpetofauna local. Foram utilizados 37 pontos amostrais de armadilhas de interceptação e queda, onde cada ponto era composto por quatro baldes conectados por cercas-guia. Armadilhas de cola e procura ativa também foram métodos utilizados para amostrar a diversidade de anfíbios e répteis. Foram registradas 21 espécies de anfíbios, 25 espécies de lagartos, 11 espécies de serpentes e uma tartaruga. Todos os métodos de amostragem contribuíram para o inventário. As curvas de rarefação e os estimadores de riqueza sugerem que a diversidade local ainda está subestimada. Nós apresentamos o grande potencial do Parque Nacional do Catimbau, caracterizado pela mais rica herpetofauna inventariada na região central do bioma, e tambémpela presença de espécies endêmicas como Amphisbaena supranumeraria e Scriptosaura catimbau, evidenciando a importância da área para a manutenção e conservação da herpetofauna da Caatinga.

Despite the increase in herpetofaunal inventories in the Caatinga biome, information for many areas is still lacking and new surveys are required. We conducted a 30-day inventory of the herpetofauna of the Catimbau National Park, Pernambuco State, Brazil. Thirty-seven pitfall trap arrays composed of 4 buckets each, along with glue traps and active searches were used to sample local herpetofaunal diversity. We recorded 21 species of frogs, 25 lizards, 11 snakes, and 1 chelonian. All sampling methods contributed significantly to achieve the amphibian and reptile diversity recovered in the inventory. Rarefaction curves and richness estimators suggest that local biodiversity is still underestimated. We attempted to show the great potential of Catimbau National Park, characterized by the richest herpetofauna surveyed in a core region of the biome, along with the presence of endemic species such as the worm snake Amphisbaena supranumeraria and the limbless lizard Scriptosaura catimbau, underscoring the importance of the area for the conservation and maintenance of the Caatinga herpetofauna biodiversity.

Aspectos da ecologia e da história natural de Phyllomedusa azurea foram estudados em uma área de cerrado do Brasil Central, entre abril de 2006 e fevereiro de 2007. As observações foram realizadas entre as 18:00 e 5:00 h. Os aspectos investigados são referentes aos nichos espacial, temporal e trófico, morfometria e reprodução. A maioria dos animais vocalizou em locais com predominância do estrato herbáceo e de dossel aberto. Os principais substratos utilizados foram arbustos e árvores. Com relação às alturas de empoleiramento, os animais foram encontrados principalmente em locais entre 0,50 e 1,00 m de altura. As amplitudes de nicho espacial (substrato e altura de empoleiramento) foram respectivamente 2,91 e 3,83. A maioria dos animais foi encontrada próxima a corpos d'água lênticos, normalmente até 0,50 m. É possível que essas características estejam primariamente relacionadas com a filogenia do gênero e secundariamente às necessidades particulares da espécie e à disponibilidade local de recursos. Os arbustos e árvores utilizados pela espécie servem como sítios de vocalização e ovoposição. Os espécimes de Phyllomedusa azurea foram localizados principalmente entre às 20:00 e 21:00 h. A largura de nicho temporal estimada (horário de atividade) foi de 4,68. Padrão reprodutivo prolongado foi também observado, predominando nos meses de maior temperatura e umidade (setembro a fevereiro). A dieta constituiu-se de 11 itens, sendo que o item mais importante para as fêmeas foi Orthoptera (IVI = 63) e para os machos Araneae (IVI = 43). As amplitudes numérica e volumétrica do nicho trófico foram respectivamente 1,80 e 1,16, para fêmeas, e 4,03 e 3,92, para machos. Machos e fêmeas diferiram em tamanho (CRC) e massa, com as fêmeas sendo maiores e mais pesadas. Os tamanhos dos menores indivíduos reprodutivos de machos e fêmeas foram 34,64 e 40,33 mm, respectivamente. Diferenças no tamanho podem estar relacionadas a distintos investimentos na reprodução pelos dois sexos.

Aspects of the ecology and natural history of Phyllomedusa azurea were investigated in an area of Central Brazilian Cerrado between April, 2006, and February, 2007. Observations were conducted between 6:00 PM and 5:00 AM. The study focused on spatial, temporal, and trophic niches, morphometry and reproduction. Most animals were recorded vocalizing in places dominated by herbaceous vegetation and an open canopy. The main substrates used were bushes and trees, and animals were seen perched most often between 0.5 and 1.0 m of height. Spatial niche breadth was 2.91 and 3.83 for substrate and perch height, respectively. Most animal were sighted close to lentic water bodies, usually up to 0.50 m. It is possible that these characteristics are related primarily to the phylogeny of the genus and secondarily to the specific needs of the species and the local availability of resources. The bushes and trees were used by the species mainly as sites of vocalization and oviposition. Specimens of Phyllomedusa azurea was sighted most frequently between 8:00 PM and 9:00 PM. Estimated temporal niche breadth (activity period) was 4.68. Prolonged reproductive pattern was also observed predominantly in the months with higher temperature and higher humidity (September to February). The diet consisted of eleven items. The most important prey taxon for the females was Orthoptera (IVI = 63), whereas for the males, it was Araneae (IVI = 33). The breadths numeric and volumetric of the trophic niche, was respectively 1.80 and 1.16, for females, and 4.03 and 3.92, for males. Males and females differed in size (SVL) and mass, with the females being larger and heavier. The sizes of smaller reproductive individuals males and females were 34.64 and 40.33 mm, respectively. Differences in size may be related to different investments in reproduction by the two sexes.

Aspectos da ecologia de Leptodactylus mystacinus e Leptodactylus fuscus foram investigados em uma área de Cerrado do Brasil Central. O estudo incluiu o uso do microhábitat, padrões de atividade, dieta e morfometria. As observações foram conduzidas entre abril de 2006 a fevereiro de 2007. As espécies são sexualmente dimórficas - fêmeas maiores que os machos - e o tamanho do corpo em L. mystacinus é maior do que o de L. fuscus. Ambas as espécies preferiram a superfície do solo (microhábitat) de hábitats brejosos com vegetação herbácea próximos a corpos lênticos de água. Leptodactylus mystacinus foi mais observado em Outubro e Novembro (20:00-20:59 e 23:00-23:59 horas) e L. fuscus em Novembro e Outubro das 19:00 às 20:59 horas. A dieta destas populações foi baseada em Arthropoda, primariamente Coleoptera, a qual foi a mais importante ordem (IVI). Diferenças nas proporções volumétricas das categorias de presas utilizadas, e nos períodos em que são mais observadas, provavelmente sejam os fatores que mais contribuem para a coexistência das duas espécies na área. Diferenças intersexuais na dieta foram observadas para estas espécies. Estas diferenças estão provavelmente associadas à alocação diferencial de recursos para a produção de gametas ou diferenças ocasionais no uso do espaço pelos dois sexos.

Aspects of the ecology of Leptodactylus mystacinus and Leptodactylus fuscus were investigated in an area of the Cerrado of Central Brazil. The study included use of microhabitat, activity patterns, diet and, morphometry. Observations were conducted between April, 2006, and February, 2007. The species are sexually dimorphic - females larger than males - and body size in L. mystacinus is larger than that of L. fuscus. Both species preferred the ground surface (microhabitat) of wetland habitats with herbaceous vegetation close to lentic water bodies. Leptodactylus mystacinus was observed most often in October and November (8:00-8:59PM and 11:00-11:59 PM), and L. fuscus in November and October between 7:00 PM and 8:59 PM. The diet of both populations was based on Arthropoda, primarily Coleoptera, which was the most important order (IVI). Differences in the volumetric proportions of the categories of then preys used, and in the periods when they were most observed, are probably the factors that contribute the most to the coexistence of both species in the area. Intersexual differences in the diet were observed in both species. These differences were probably associated with the differential allocation of resources to the production of gametes or occasional differences in the use of space by the two sexes.

OBJETIVO: Estudar os resultados da técnica descrita por Carreira et al. com utilização de perfusão cerebral seletiva bilateral (PCSAB) pelo isolamento do tronco braquiocefálico e artéria carótida esquerda. MÉTODOS: Quinze pacientes foram operados consecutivamente entre de junho de 2005 e setembro de 2007. Os dados foram analisados por programa informatizado Epi Info e significância estatística com p<0,05. RESULTADOS: No grupo analisado, 53,3% dos pacientes eram do sexo masculino e a idade média era de 59,86±15,4 anos. Com relação à doença de base, 60% dos pacientes apresentavam dissecção aguda do tipo A, 6,7% tipo B e 33,3% aneurisma da aorta e arco. O tempo médio de CEC e de anoxia foi de 177,6±39,4 e 135,9±34,0 minutos, respectivamente. Nesse grupo, 86,7% dos pacientes não foram submetidos a parada circulatória total, com tempo médio de PCSA unilateral e bilateral de 10,9±2,0 e 57,2±21,2 minutos, respectivamente. A temperatura média da hipotermia foi de 23,0±2,9ºC. A artéria subclávia esquerda foi ligada em dois (13,3%) pacientes, e nove (60%) foram submetidos a anastomoses proximal e distal com tubos separados. Utilizou-se endoprótese vascular na aorta descendente em quatro (26,7%) pacientes. Três (20%) pacientes morreram, todos do subgrupo de dissecção aguda. Nenhum dos sobreviventes apresentou seqüelas neurológicas, com média de acompanhamento tardio de 11,7±9,6 meses. Nenhum dos fatores estudados apresentou relação estatisticamente significativa com a mortalidade (p>0,05). CONCLUSÃO: A técnica de PCSAB é reprodutível e apresenta resultados semelhantes aos da literatura mundial. A excelente evolução neurológica e o fácil controle de sangramentos nas linhas de sutura podem ter contribuído com os resultados obtidos.

OBJECTIVE: To evaluate the results of a technique described by Carreira et al. using bilateral antegrade selective cerebral perfusion by isolating the brachiocephalic trunk and the left carotid artery. METHODS: Fifteen patients were operated between June 2005 and September 2007. Data analysis were performed using Epi Info and statistical significance was set at p<0.05. RESULTS: Of the 15 patients, 53.3% were male; mean age was 59.86±15.4 years; 60% presented with type A acute aortic dissection; 6.7% type B; and 33.3% aneurysm of aorta and arch. Mean CPB and aortic clamping time was 177.6±39.4 and 135.9±34.0 minutes, respectively. In this group, 86.7% were not submitted to total circulatory arrest, with mean unilateral and bilateral selective cerebral perfusion time of 10.9±2.0 and 57.2±21.2 minutes, respectively. Mean hypothermic temperature was 23.0±2.9ºC. Two had left subclavian artery ligature, 60% used separated aortic grafts, and four used aortic endoprosthesis. Three (20%) patients died, all of them in the acute aortic dissection group. There were no neurological complications. The mean follow up time was 11.7±9.6 months. Regarding mortality, none of the parameters were statistically significant (p>0.05). CONCLUSION: The technique of bilateral selective cerebral perfusion described by Carreira et al. can be performed by others and presents similar results to the international literature. The excellent neurological outcome and easy bleeding control on surgical sutures lines are the major advantages of this new procedure.

Aspectos ecológicos e da biologia reprodutiva de Tropidurus oreadicus foram investigados em uma área de cerrado rupestre do Brasil Central. Foram estudados a morfometria, o uso do microhábitat, o padrão de atividade, a dieta e características da biologia reprodutiva de T. oreadicus em Cocalzinho - GO, de abril a setembro/2003. São animais sexualmente dimórficos, com os machos adultos maiores que as fêmeas. O microhábitat preferencial utilizado pela espécie foi a superfície das rochas (hábito saxícola). A espécie mostrou padrão de atividade unimodal. Foram frequentemente observados parados e expostos ao sol entre 9:00 e 10:59 horas. A alimentação desta população de T. oreadicus é baseada em formigas, larvas de inseto e besouros. Além disso, apresentaram mudanças ontogenéticas e diferenças intersexuais na dieta. Provavelmente essas diferenças estejam associadas à alocação diferenciada dos recursos para o crescimento ou produção dos gametas. A reprodução é provavelmente sazonal ocorrendo principalmente nos meses de maior pluviosidade.

Ecological aspects and of the reproductive biology of Tropidurus oreadicus was investigated in a rocky cerrado area in Central Brazil. It was studied the morphometry, the microhabitat use, the activity pattern, the diet and the characteristics of the reproductive biology of T. oreadicus in Cocalzinho-GO, from April to September/2003. They are sexually dimorphic animals, with adult males larger than females. The preferential microhabitat used by the species was the surface of the rocks (saxicolous habit). The species shows a unimodal activity pattern. It was frequently observed resting and exposed to the sun between 9:00 and 10:59 hours. This T. oreadicus population feed upon ants, larvae of insects and beetles. Besides it presented ontogenetics shift and intersexual differences in the diet. Probably these differences were associated with the differentiated allocation of the resources for the growth or production of gamete. The reproduction is probably seasonal occurring mainly during the months of higher rainfall.
