ABSTRACT Introduction: The aims of this study were to determine the incidence of severe and moderate primary graft dysfunction (PGD) in our center, to identify, retrospectively, donors’ and recipients’ risk factors for PGD development, and to evaluate the impact of PGD within 30 days after heart transplantation. Methods: Donors’ and recipients’ medical records of 64 consecutive adult cardiac transplantations performed between January 2016 and June 2017 were reviewed. The International Society for Heart and Lung Transplantation (ISHLT) criteria were used to diagnose moderate and severe PGD. Associations of risk factors for combined moderate/severe PGD were assessed with appropriate statistical analyses. Results: Sixty-four patients underwent heart transplantation in this period. Twelve recipients (18.7%) developed severe or moderate PGD. Development of PGD was associated with previous donor cardiopulmonary resuscitation and a history of prior heart surgery in the recipient (P=0.01 and P=0.02, respectively). The 30-day in hospital mortality was similar in both PGD and non-PGD patients. Conclusion: The use of the ISHLT criteria for PGD is important to identify potential risk factor. The development of PGD did not affect short-term survival in our study. More studies should be done to better understand the pathophysiology of PGD.

ABSTRACT The immediate need for the increase in wheat production to meet the future world demand, associated with the occurrence of drastic climatic events, such as drought, makes it necessary to develop drought-resilient genotypes. The aims of this work were to evaluate the use of drought-tolerance indices for the selection of wheat genotypes, to compare the genetic gains in grain yield using different selection strategies by means of a multi-trait index, and to select superior drought-tolerant wheat genotypes. The total of 31 tropical wheat lines was evaluated in two experiments. Five agronomic traits were accessed. The grain yield data from the stress and nonstress experiments were used to obtain five drought-tolerance indices. The data were subjected to mixed model analysis, and four selection scenarios were designed. There was a significant effect of genotype for all traits. The inclusion of drought-tolerance indices in the selection index provided superior genetic gains in drought condition. Seven lines were selected due the high frequency of favorable alleles for drought-tolerance and other important agronomic traits. Drought-tolerance indices are appropriate for characterizing the response of wheat genotypes to drought-stress. The inclusion of drought-tolerance indices along with agronomic traits in multi-trait selection strategies provides for superior gains in grain yield compared to the non-inclusion of the indices.

Abstract In the Amazon, local electrical energy production is very important due to the large number of isolated communities, usually far from the conventional grid. In this context, steam turbines are relevant technologies to be used in the region, since waste biomass is widely available in several communities, besides, where sustainable agricultural activities take place, such as the use of açaí seeds, sugarcane bagasse, among others. Currently, there are not many relevant studies in the literature for small steam turbines operating at low pressure, conditioned to the reality of the Amazon region. Hence, the main goal of this work is to develop an experimental study of a small steam turbine operating at low pressure, in order to apply it to small energy demand, typically found in the Amazon. We developed measurements on the behavior of mechanical and electrical powers in relation to the shaft rotational speed of the small steam turbine, taking into account pressures of 0.1, 0.2 and 0.3 MPa. We concluded that the preliminary experimental survey, made in this work, demonstrates a good mechanical behavior of the small turbine and could be an alternative for electricity generation system to supply small demands in isolated communities in the Amazon, taking advantage of biomass from sustainable agricultural activities.

Resumo Na Amazônia, a produção local de energia elétrica é muito importante devido ao grande número de comunidades isoladas, geralmente distantes da rede convencional. Nesse contexto, as turbinas a vapor são tecnologias relevantes a serem utilizadas na região, uma vez que a biomassa está amplamente disponível em diversas comunidades, inclusive, onde ocorrem atividades agrícolas sustentáveis como a utilização do caroço do açaí, bagaço de cana, entre outros. Atualmente, não existem muitos estudos relevantes na literatura para pequenas turbinas a vapor operando em baixa pressão, condicionadas à realidade da região amazônica. Assim, o objetivo principal deste trabalho é desenvolver um estudo experimental de uma pequena turbina a vapor operando em baixa pressão, a fim de aplicá-la a pequenas demandas de energia, tipicamente encontradas na região. Desenvolvemos medições do comportamento das potências mecânica e elétrica em relação à velocidade de rotação do eixo da pequena turbina a vapor, levando em consideração as pressões de 0,1, 0,2 e 0,3 MPa. Concluímos que o levantamento experimental preliminar, feito neste trabalho, demonstra um bom comportamento mecânico da pequena turbina e pode ser uma alternativa para o sistema de geração de energia elétrica suprir pequenas demandas em comunidades isoladas na Amazônia, aproveitando a biomassa oriunda de atividades agrícolas sustentáveis.

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.

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.

Abstract This study aimed to investigate whether two acquisition parameters, voxel size and filter thickness, used in a micro-computed tomography (micro-CT) scan, together with the examiner’s experience, influence the outcome of bone repair analysis in an experimental model. Bone defects were created in rat tibiae and scanned using two voxel sizes of 6- or 12-µm and two aluminum filter thickness of 0.5- or 1-mm. Then, bone volume fraction (BV/TV) and trabecular thickness (Tb.Th) were analyzed twice by two groups of operators: experienced and inexperienced examiners. For BV/TV, no significant differences were found between scanning voxel sizes of 6 and 12 µm for the experienced examiners; however, for the inexperienced examiners, the analysis performed using a 12-µm voxel size resulted in higher BV/TV values (32.4 and 32.9) than those acquired using a 6-µm voxel size (25.4 and 24.8) (p < 0.05). For Tb.Th, no significant differences between the analyses performed by experienced and inexperienced groups were observed when using the 6-µm voxel size. However, inexperienced examiners’ analysis revealed higher Tb.Th values when using the 12-µm voxel size compared with 6 µm (0.05 vs. 0.03, p < 0.05). Filter thickness had no influence on the results of any group. In conclusion, voxel size and operator experience affected the measured Tb.Th and BV/TV of a region with new bone formation. Operator experience in micro-CT analysis is more critical for BV/TV than for Tb.Th, whereas voxel size significantly affects Tb.Th evaluation. Operators in the initial phases of research training should be calibrated for bone assessments.

Abstract Microbialites are the most abundant life evidence in Precambrian sedimentary rocks. They are produced by microbial interaction activity and sedimentary processes reflecting paleoenvironmental conditions. The Ediacaran-Cambrian carbonate and siliciclastic successions in the Southern Amazon Craton in Central Brazil, provide a key opportunity to understand how the metazoan life coexisted with the microbial communities. The spatial and temporal distribution of microbialites as well as morphological and paleoenvironmental changes have been assessed, reinterpreting previous works and including new data from the Araras-Alto Paraguai and Corumbá basins. The deposition was controlled by subsidence and sea-level changes that affected these basins, considered extensions of epicontinental seas during the Gondwana assembly. The stromatolites are restricted to coastal deposits and experienced thriving flourishment intervals after the Marinoan Glaciation (635 Ma). Post-glacial transgression was marked by microbial colonization in shallow platforms represented by stratiform and giant domical stromatolites in the Araras-Alto Paraguai Basin. The continuity of the transgression generated a moderately deep aragonite sea at about 622 Ma. A progressive sea-level fall caused the implantation of coastal environments under greenhouse conditions with tidal flat and sabkha settings colonized by centimetric-scale stromatolites. The sea retreat was accompanied by progressive uplift, causing a moderate inversion of the basin and erosion of the succession until ~560 Ma with the deposition of the last preserved tidal flat deposits with the occurrence of thrombolites. The subsiding Corumbá Basin was the site of microbially-induced deposition of carbonates in a shallow platform connected to an offshore setting with the proliferation of metazoan straddling the Ediacaran-Cambrian boundary. Microbial communities were restricted to lagoon deposits during the Lower Cambrian transgression in the Araras-Alto Paraguai Basin and the last phase refers to the sea retreat towards southeast, developing a fluvial system connected with the arid and evaporitic tidal flats colonized by microbialites that lasted until the upper Cambrian. Except for the post-glacial stromatolites, the columnar and domal microbialite indicate that the coastal settings dominated the Ediacaran-Cambrian transition. The preservation of microbialites in the post-glacial intervals can be associated with the Mg-Ca-CO3 oversaturation in dolomitic platforms. The rapid calcification and ability to resist the dissolution and replacement have increased the stromatolites’ preservation potential reported here, where its well-preserved occurrence in tidal flats and sabkha occurs due to intense early diagenetic silicification. The change from carbonate accumulation to siliciclastic-rich environments contributed to the demise of microbially-induced strata. In general, the scarce coexistence between coastal stromatolite and metazoan-bearing marine deposits makes it challenging to establish a competitive relationship between these organisms, as previously postulated.

Resumo Com o objetivo de avaliar a microarquitetura óssea cortical e a morfologia dos osteons após irradiação, foram utilizados doze coelhos machos da Nova Zelândia. Os animais foram divididos: grupo controle (sem radiação-NIr); e 3 grupos irradiados, sacrificados após: 7 (Ir7d); 14 (Ir14d) e 21 (Ir21d) dias. Foi utilizada uma dose única de radiação de 30 Gy. A microtomografia computadorizada analisou a microarquitetura cortical: espessura cortical (CtTh), volume ósseo (BV), porosidade total (Ct.Po), porosidade intracortical (CtPo-cl), número de canal/ poro (Po.N), dimensão fractal (DF) e grau de anisotropia (Ct.DA). Após a varredura, a morfologia dos osteosn foi avaliada histologicamente por meio de: Área e perímetro do osteon (O.Ar; O.p) e dos canais de Havers (C.Ar; C.p). A análise microtomográfica foi realizada por ANOVA, seguida pelos testes de Tukey e Dunnet. As análises morfológicas do osteon foram realizadas por Kruskal-Wallis e testadas por Dunn. A espessura cortical foi diferente (p<0,010) entre os grupos controle e irradiados, com córtex mais espesso no Ir7d (1,15±0,09). A porosidade intracortical revelou diferenças significativas (p<0,001) entre os grupos irradiados e o controle, com menor valor para Ir7d (0,29±0,09). O volume ósseo foi menor no Ir14d em relação ao controle. Área e perímetro do osteon foi diferente (p<0,0001) entre o controle e Ir7d. Os canais haversianos também revelaram valores mais baixos (p<0,0001) em Ir7d (80.57±9.3; 31.63±6.5) em relação ao controle e demais grupos irradiados. A microarquitetura cortical é afetada pela radiação e os efeitos parecem ser dependentes do tempo, principalmente em relação à morfologia dos osteons nos dias iniciais. A estrutura cortical em Ir21d revelou semelhanças com o controle, sugerindo que a microarquitetura se assemelha à condição normal após um período.

Abstract Aiming to evaluate cortical bone microarchitecture and osteonal morphology after irradiation, twelve male New Zealand rabbits were used. The animals were divided: control group (no radiation-NIr); and 3 irradiated groups, sacrificed after: 7 (Ir7d); 14 (Ir14d) and 21 (Ir21d) days. A single radiation dose of 30 Gy was used. Computed microtomography analyzed the cortical microarchitecture: cortical thickness (CtTh), bone volume (BV), total porosity (Ct.Po), intracortical porosity (CtPo-cl), channel/pore number (Po.N), fractal dimension (FD) and degree of anisotropy (Ct.DA). After scan, osteonal morphology was histologically assessed by means: area and perimeter of the osteons (O.Ar; O.p) and of the Haversian canals (C.Ar; C.p). Microtomographic analysis were performed by ANOVA, followed by Tukey and Dunnet tests. Osteon morphology analyses were performed by Kruskal-Wallis, and test Dunn’s. Cortical thickness was significant difference (p<0.010) between the NIr and irradiated groups, with thicker cortex at Ir7d (1.15±0.09). The intracortical porosity revealed significant difference (p<0.001) between irradiated groups and NIr, with lower value for Ir7d (0.29±0.09). Bone volume was lower in Ir14d compared to control. Area and perimeter of the osteons were statistically different (p<0.0001) between NIr and Ir7d. Haversian canals also revealed lower values (p<0.0001) in Ir7d (80.57±9.3; 31.63±6.5) compared to NIr and irradiated groups. Cortical microarchitecture was affected by radiation, and the effects appear to be time-dependent, mostly regarding the osteons morphology at the initial days. Cortex structure in Ir21d revealed similarities to control suggesting that microarchitecture resembles normal condition after a period.

SUMMARY The extracorporeal membrane oxygenation (ECMO) is a procedure that has been used for a long time in reference centers worldwide. Its fundamental precept is to serve as a bridge to a definitive treatment in patients with severe, but potentially reversible, clinical conditions. Despite this, its use in cardiopulmonary arrest (ECPR) is still a matter of debate, especially when indicated in the emergency department. There is not yet a sufficient level of evidence to support its routine use. In Brasil, the procedure stopped being considered an experimental technique by the Federal Council of Medicine only in 2017. The objective of the present case is to share the pioneering spirit of a Brazilian reference center with ECPR in the emergency room and to discuss the future challenges of the ECMO technique.

ABSTRACT The objective of the present study was to analyse the association between the level of physical activity and mental health indicators in this population. A total of 254 military police officers, male and female, aged between 21 and 55, participated in military battleships and police companies in the metropolitan region of Aracaju, Sergipe. They responded to an assessment form, available online, on Google Forms, containing questions about socio-demographic, anthropometric and occupational characteristics, quality of sleep (Pittsburgh scale), stress (EPS-10), anxiety and depression (HAD scale), Exhaustion syndrome (MBI - GS), suicidal ideation (YRBSS - adapted), and Physical Activity level (IPAQ-short). Officers classified as "insufficiently active" had a higher risk for "burnout syndrome" (OR = 2.49; CI: 95% 1.42-4.43) and a greater feeling of "deep sadness" (OR = 1.85; CI: 95% 1.03-3.33) compared with physically active colleagues. In addition, longer service time was a protective factor against anxiety (OR = 0.30; CI: 95% 0.13-0.68), burnout syndrome (OR = 0.28; CI: 95% 0.12 -0.67) and deep sadness (OR = 0.25; CI: 95% 0.11-0.57). Older officers are more likely to be affected by "deep sadness" (OR = 2.80; CI: 95% 1.37-5.71). It was concluded that physical activity is associated with changes in the mental health of the police officers evaluated.

RESUMO O objetivo desse estudo foi analisar a associação entre as características antropométricas, ocupacionais, nível de atividade física e à ideação suicida em policiais militares de Aracaju e Região Metropolitana, Brasil. Participaram do estudo 254 policiais militares ativos do sexo masculino e feminino, com idade entre 21 e 55 anos. Os dados foram coletados através do Formulários Google, contendo questões sobre características sociodemográficas, antropométricas, ocupacionais e comportamentos de risco. Foi realizada estatística descritiva com média, desvio padrão, frequência absoluta, relativa e para os casos específicos, análise de regressão logística binária. Policiais militares com menos tempo de serviço tinham quatro vezes mais chances de apresentar tristeza profunda nos últimos 12 meses (OR = 0,22; 95% IC 0,09-0,51), e policiais mais velhos três vezes mais chances (OR = 3,12; 95% IC 1,64-7.97). Policiais que trabalhavam em turnos do dia alternados, apresentaram quatro vezes mais chances de ter planejado suicídio nos últimos 12 meses (OR = 4,67; 95% IC 1,08-20,16), e policiais com menos tempo de serviço apresentaram sete vezes mais chances (OR = 0,13; 95% IC 0,26-0,64). É observado que as características laborais estão associadas a ideação suicida. Também é percebido que à atividade física é um fator de proteção contra tristeza profunda.

ABSTRACT This study aimed to analyse the association between anthropometric characteristics, occupational status, physical activity level, and suicidal ideation among military police in Aracaju and the Metropolitan Region, Brazil. 254 active male and female military policemen, aged between 21 and 55 years, participated in the study. 254 military police participated in the study. Data were collected through Google Forms, containing questions about sociodemographic, anthropometric, occupational characteristics, and risk behaviours. Military officers with less service were four times more likely to experience profound sadness in the past 12 months (OR = 0.22; 95% CI 0.09-0.51), and older officers three times more likely (OR = 3.12; 95% CI 1.64-7.97). Police officers who worked alternate day shifts were four times more likely to have planned suicide in the past 12 months (OR = 4.67; 95% CI 1.08-20.16), and police officers with less time on duty had seven times more chances (OR = 0.13; 95% CI 0.26-0.64). It is observed that labour characteristics are associated with suicidal ideation. It is also perceived that physical activity is a protective factor against profound sadness.

ABSTRACT This study aimed to evaluate the relationship between the level of physical activity and the anthropometric profile, perception of quality of life, and mental health in military police officers from the State of Sergipe (PM / SE). This cross-sectional study involved 30 male military police officers, aged 28 to 40 years. They used the pedometer for four days, then answered questionnaires about: Demographic, Anthropometric, and Occupational Data; IPAQ short version; WHOQOL; Anxiety, Depression and Stress Scale. They had a prevalence of active police (70%) and had no symptoms for problems that affect mental health. 66.67% reported good perception and quality of life, and 70% were satisfied with their health. There was a correlation between the level of physical activity and stress on the day of service and the first day off with quality-of-life indicators. There was a correlation between the activity level of the first day off with the Physical (R = 0.411; p <0.05) and the Environment (R = 0.511; p <0.05) domains. Good levels of mental health were presented. As for the level of physical activity, there was a positive relationship between the day of service and the stress variable. There were positive relationships between the activity level of the first day off and the Physical and Environment domains regarding Quality of Life.
