RESUMO Objetivos: Analisar as notificações de morte encefálica (ME) recebidas pela Central de Transplantes (CET) do estado de Roraima (RR) de 2017 a 2021. Métodos: Trata-se de estudo transversal, quantitativo e observacional no qual foram analisadas todas as notificações recebidas pela CET no período de 2017 a 2021, resultando em 120 pacientes, dos seguintes centros de saúde: Hospital Geral de Roraima (HGR), Hospital Confederação Nacional das Cooperativas Médicas (UNIMED), Hospital da Criança Santo Antônio (HCSA), Hospital das Clínicas (HC) e Hospital Lotty Íris (HLI). Os dados foram coletados do sistema de gerenciamento de dados da central e repassados para a ficha de coleta desenvolvida pela pesquisadora. Resultados: Este estudo analisou 119 notificações após a exclusão de uma devido a dados conflitantes. Houve predominância do sexo masculino (58%), com trauma cranioencefálico sendo a causa mais frequente de ME. Ao todo, foram realizadas seis captações de órgãos, todas no HGR. Este estudo não encontrou associações significativas entre a captação de órgãos e sexo, idade, local de internação e ano. Conclusão: Há grandes desafios em relação à doação de órgãos em RR, com uma taxa de captação baixa ao longo de 5 anos. Apenas o HGR obteve sucesso em realizar captações de órgãos, diferentemente de outros hospitais notificadores. São necessárias melhorias, destacando a importância de se realizarem mais estudos para uma análise mais aprofundada dos dados.

ABSTRACT Objectives: To analyze brain death (BD) notifications received by Central de Transplantes (CET) in the state of Roraima (RR) from 2017 to 2021. Methods: This is a cross-sectional, quantitative, and observational study, where all notifications received by CET from 2017 to 2021 were analyzed, resulting in 120 patients from health the following centers: Hospital Geral de Roraima (HGR), Hospital Confederação Nacional das Cooperativas Médicas (UNIMED), Hospital da Criança Santo Antônio (HCSA), Hospital das Clínicas (HC), and Hospital Lotty Íris (HLI). The data were collected from the center’s data management system and passed on to the collection form developed by the researcher. Results: This study analyzed 119 notifications after excluding one due to conflicting data. There was a predominance of males (58%), with traumatic brain injury being the most frequent cause of BD. Six organ harvestings were carried out, all at the HGR. This study found no significant associations between organ procurement and sex, age, place of hospitalization, and year. Conclusion: There are considerable challenges concerning organ donation in RR, with a low uptake rate over five years. Only the HGR successfully carried out organ harvesting, while other reporting hospitals were unsuccessful. Improvements are needed, highlighting the importance of more studies for a more in-depth data analysis.

Abstract This study aimed to identify and characterize the antimicrobial susceptibility profile of bacteria found in primary endodontic infections in the teeth of patients treated at the Dental Clinic of the University of Ribeirão Preto, São Paulo, Brazil. From September to December 2019, samples were obtained from 21 patients with primary endodontic infections. The collections were carried out in triplicate using paper cones placed close to the total length of the root canal. Bacterial isolation was performed in Brain Heart Infusion agar, Blood agar, and other selective culture media cultured at 37°C for up to 48 h under aerobiosis and microaerophilic conditions. The bacterial species were identified using the Vitek 2 automated system. The disk diffusion method on agar Müeller–Hinton was used to assess antimicrobial susceptibility with the recommended antimicrobials for each identified bacterial species. A total of 49 antibiotics were evaluated. Fifteen of the 21 samples collected showed bacterial growth, and 17 bacterial isolates were found. There were 10 different bacterial species identified: Enterococcus faecalis (four isolates), Streptococcus mitis/oralis (three isolates), Streptococcus anginosus (three isolates) being the most common, followed by Staphylococcus epidermidis, Enterococcus faecium, Streptococcus constellatus, Streptococcus alactolyticus, Enterobacter cloacae, Klebsiella variicola, and Providencia rettgeri (one isolate of each species). The analysis demonstrated significant susceptibility to most of the tested antibiotics. However, some Enterococcus isolates resisted the antibiotic’s erythromycin, ciprofloxacin, and tetracycline. A Staphylococcus epidermidis isolate was characterized as multidrug-resistant. Five Streptococcus isolates were non-susceptible to all antibiotics tested.

Resumo Este estudo avaliou estabilidade de cor (EC), efeito antiaderente (EAA) e viabilidade celular de microrganismos em superfície de resina acrílica (RA), tratada com solução de fitoesfingosina, associada ou não ao percarbonato de sódio (PS). Espécimes RA foram preparados e análise de cor foi realizada antes e após os tratamentos e EC foi calculada. Para análise de EAA, as amostras foram esterilizadas por radiação em forno de micro-ondas. Então foram distribuídas aleatoriamente: solução salina tamponada com fosfato (PBS - controle), hipoclorito de sódio 0,5% (SH), fitoesfingosina (PHS) e fitoesfingosina + SP (PHS+Na2CO3). Os espécimes permaneceram em contato com as soluções por 30 minutos e posteriormente foram contaminados por Candida albicans. Alíquotas foram semeadas em placas de Petri com ágar Sabouraud Dextrose e incubadas a 37°C por 24 horas. Após a incubação, o número de colônias foi contado. A viabilidade celular dos microorganismos aderidos na RA foi avaliada e 20 campos foram observados em microscópio de epifluorescência, e a porcentagem de células viáveis aderidas foi calculada. Os dados foram comparados (One-way ANOVA, Tukey, p<0,05). Quanto a EC, o PHS+ Na2CO3 [0,4 (0,1)] resultou em menor alteração que o PBS [0,9 (0,2)], semelhante aos demais grupos (SH [1,0 (0,3)]; PHS [0,9 (0,2)]). Não houve diferença para todas as soluções testadas quanto à capacidade de evitar a aderência de microorganismos (p>0,05), mas o PHS [11,2 (4,1)] resultou em uma área menor de células viáveis aderidas, estatisticamente diferente do SH [18,2 (7,6)] e PBS [26,4 (10,8)]. Concluiu-se que o PHS resultou em menor número de células viáveis aderidas e, quando associado ao Na2CO3, também apresenta menor efeito sobre o EC da RA. , (EC) EAA (EAA RA, (RA) PS. PS .

Abstract This study evaluated color stability (CS), anti-adherence effect (AAE), and cell viability of microorganisms on acrylic resin (AR) surface, treated associated or not with sodium percarbonate (SP). AR specimens were prepared, and color analysis was performed before and after the treatments and the CS was calculated. For analysis of AAE, the samples were sterilized by radiation in a microwave oven. Then samples were randomly distributed: phosphate-buffered saline (PBS - control), 0.5% sodium hypochlorite (SH), phytosphingosine (PHS), and phytosphingosine + SP (PHS+Na2CO3). The specimens remained in contact with solutions for 30 minutes and were later contaminated by Candida albicans. Aliquots were seeded in Petri dishes with Sabouraud Dextrose agar and incubated at 37°C for 24 hours. After the incubation, the number of colonies was counted. The cell viability of adhered microorganisms on the AR was evaluated and 20 fields were observed under an epifluorescence microscope, and the percentage of adhered viable cells was calculated. Data were compared (One-way ANOVA, Tukey, p<.05). As for CS, PHS+ Na2CO3 (0.4±0.1) resulted in less change than PBS (0.9±0.2), similar to the other groups (SH [1.0±0.3)]; PHS [0.9±0.2)]). There was no difference for all tested solutions regarding the ability to avoid microorganism adherence (p>0.05), but PHS (11.2±4.1) resulted in a smaller area of adhered viable cells, statistically different from SH (18.2±7.6) and PBS (26.4±10.8). It was concluded that PHS resulted in lower adhered viable cells and when associated with Na2CO3, also shows a lower effect on the CS of AR. , (CS) antiadherence anti AAE (AAE) (AR surface SP. .

Resumo O objetivo deste estudo foi descrever a prevalência de idosos com uma ingestão adequada de água e seus fatores associados. Estudo transversal de base populacional realizado em 2014 com idosos (≥ 60 anos) participantes do estudo “COMO VAI?”. Investigou-se o número de copos de água ingeridos/dia pelos entrevistados, considerando-se adequada a ingestão de pelo menos oito copos/dia. As variáveis independentes foram características sociodemográficas, comportamentais e de saúde. A regressão de Poisson foi utilizada para a investigação das associações. Foram entrevistados 1.451 idosos, sendo observado que uma baixa percentagem, 12,6% (IC95% 10,8; 14,7) referiu consumo adequado de água. Maior percentagem de consumo adequado de água foi observada nos idosos mais jovens, com excesso de peso, que apresentaram cinco ou mais doenças e que eram mais dependentes quanto à capacidade funcional. A tendência decrescente de ingestão de água em relação à idade torna essencial o desenvolvimento de ações voltadas para essa população de maior risco acerca da importância de uma ingestão hídrica adequada e das possíveis consequências do seu consumo inadequado. associados 201 ≥ ( 6 anos COMO VAI.

Abstract The scope of this study was to determine the percentage of elderly individuals receiving an adequate water intake and associated factors among non-institutionalized elderly individuals in the urban area of Pelotas, Rio Grande do Sul. It involved a cross-sectional, population-based study carried out in 2014 with elderly participants (≥ 60 years) of the “COMO VAI?” survey. The amount of water ingested per day of the interviewees was investigated, considering the intake of at least eight glasses per day to be adequate. The independent variables were sociodemographic, behavioral, and health characteristics, and Poisson Regression was used to investigate associations. A total of 1,451 elderly people were interviewed, with only 12.6% (95%CI 10.8; 14.7) drinking a sufficient amount. A higher percentage of the elderly with adequate water consumption was observed in younger elderly individuals, those overweight, those with five or more diseases, and those who were more impaired. A low percentage of the elderly with an adequate water intake was observed among the elderly adults in the study. The decreasing trend of water intake in relation to age highlights the importance of developing actions for the higher risk population to stress adequate water intake and the possible consequences of the lack of adequate consumption. noninstitutionalized non institutionalized Pelotas Sul crosssectional, crosssectional cross sectional, sectional cross-sectional populationbased based 201 ≥ ( 6 years COMO VAI VAI? survey investigated sociodemographic behavioral characteristics associations 1451 1 451 1,45 interviewed 126 12 12.6 95%CI 95CI CI 95 10.8 108 10 8 14.7 147 14 7 overweight diseases impaired 20 145 45 1,4 12. 9 10. 14. 2 4 1,

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

RESUMO. Cuidadores informais de pessoas que vivem com demência tendem a sofrer problemas de saúde mental como resultado dos efeitos negativos associados às tarefas de cuidado. Assim, intervenções psicossociais para essa população são necessárias. O iSupport é um programa de apoio online para cuidadores criado pela Organização Mundial da Saúde. Objetivo: Descrever o desenho de um ensaio clínico randomizado para medir a eficácia da versão iSupport-Brasil na saúde mental e no bem-estar de cuidadores. Métodos: Os participantes serão randomizados em Grupo Intervenção (GI) (n=195) e Grupo Controle (GC) (n=195). Durante três meses, o GI acessará a plataforma iSupport-Brasil, o CG entrará na página eletrônica da Associação Brasileira de Alzheimer e ambos os grupos receberão por e-mail a versão preliminar do e-book Guia de cuidados para a pessoa idosa, do Ministério da Saúde. Os dados serão coletados em três momentos: linha de base, três e seis meses após o início da intervenção.

ABSTRACT. Unpaid caregivers of people living with dementia tend to suffer mental health problems as a result of the negative effects associated with the care tasks. Thus, psychosocial interventions for this population group are necessary. iSupport is an online support program for caregivers that was created by the World Health Organization. Objective: To describe the design of a randomized clinical trial to measure the efficacy of the iSupport-Brasil version on caregivers’ mental health and well-being. Methods: The participants will be randomized into Intervention Group (IG) (n=195) and Control Group (CG) (n=195). For three months, the IG will access the iSupport-Brasil platform, the CG will enter the electronic page of the Brazilian Alzheimer’s Association, and both groups will be emailed the preliminary version of the “Guia de cuidados para a pessoa idosa” e-book (a guide to providing care to the elderly) from the Ministry of Health. The data will be collected at three moments: baseline, and three and six months after the beginning of the intervention. Results: It is expected that it will be possible to provide diverse validity evidence about iSupport-Brasil as an online and free intervention alternative, as a preventive means and as a way to promote mental health among caregivers of people living with dementia. Conclusion: Through the evaluation protocol of this randomized clinical trial on the effects of the iSupport-Brasil program, it may become a reference for countries that plan to adapt and improve the iSupport program using digital health solutions.

Resumo Tecoma stans, popularmente conhecida como ipê-mirim é uma espécie arbórea pertencente à Família Bignoniaceae. Nativa nas Américas e Antilhas, é amplamente utilizada no Brasil, no paisagismo e na arborização urbana. A produção de suas mudas é feita por sementes e são vários os fatores que interferem neste processo e no seu posterior desenvolvimento como a época de semeadura e o substrato. O objetivo deste trabalho foi avaliar o efeito da época de semeadura e do substrato na produção de mudas de Tecoma stans. Os experimentos foram conduzidos em viveiro. O delineamento experimental foi inteiramente casualizado. Os tratamentos foram arranjados em esquema fatorial 2 × 6 sendo duas épocas de semeadura (outono e primavera) e seis substratos (SC1; SC2; SC3; SC4; areia e vermiculita); foram quatro repetições e dez plântulas por parcela. Avaliou-se a porcentagem de emergência e variáveis morfológicas. As médias foram comparadas entre si por meio do teste de Tukey (p < 0,05).

Abstract Tecoma stans is popularly known as ipê-mirim in Brazil. This species belongs to the Bignoniaceae family and it is native to Americas and Antilles, where it is widely used in landscaping as urban tree. The seedlings are produced from seeds and there are several factors that influences its development, such as the sowing time and the substrate. This work aimed to understand the effect of the sowing time and substrates on the production of Tecoma stans seedlings. The experiments were carried out in a nursery. The experimental design was completely randomized. The substrates were arranged in a 2 × 6 factorial scheme, two sowing times (autumn and spring) and six commercial substrates (SC1; SC2; SC3; SC4; sand and vermiculite) under four replicates and ten seedlings per plot. The means were compared to each other using the Tukey test (p < 0.05). There was a significant difference between the seasons of the year, showing that the percentage of emergence was higher in spring (89%). The seedlings of Tecoma stans were shown to be nutrient-dependent both in the emergence of the seedling and in the subsequent development of the seedlings, since the highest averages of the studied characteristics were obtained in the commercial substrates, as they have nutrients in their composition, with greater emphasis on SC1. ipêmirim ipê mirim Brazil Antilles tree substrate nursery randomized scheme autumn SC1 SC (SC1 SC2 SC3 SC4 vermiculite plot p 0.05. 005 0.05 . 0 05 0.05) year 89%. 89 89% (89%) nutrientdependent nutrient dependent composition (SC 00 0.0 8 (89% 0.

Abstract The volcanic Trindade Island is a remote Brazilian offshore territory in the South Atlantic, located ca. 1.140 kilometers east of the southeast coast of Brazil. The island’s permanent exposure to geological hazards requires assessment. However, the lack of erosion and landslides temporal data impedes predictive geohazard analyses. Therefore, we compiled pre-existing data from nautical charts and surveyed the surface terrain on Trindade Island to generate Digital Terrain Models (DTMs) and comparative accuracy analyses. The DTM based on pre-existing data shows the lowest accuracy (root mean square error - RMSE: 12.3 m) yet is adequate for regional studies. In contrast, the DTM developed from real-time kinematic global navigation satellite systems (RTK-GNSS) has the highest vertical accuracy (RMSE: 0.48 m), but spatial variability of ground elements was underestimated and limited to meter-sized (and larger) elements. The DTM obtained using the unmanned aerial vehicle (UAV) with ground control points (GCP), on the other hand, presented lower accuracy (RMSE: 2.37 m) than the RTK-GNSS model but still allowed observation of centimetric (and larger) ground features. For geohazard assessment on Trindade Island, models that allow fine-scale studies are needed. A UAV with GCP provides such standards and proved to be the most viable option in remote and complex sites as well. Hence, this study, the first to allow multi-temporal analysis of geohazard assessment on Trindade Island, offers a viable solution for similar analyses in other remote locations.

Resumo As sementes de palmeiras apresentam indicativo de serem recalcitrantes e a germinação, para muitas espécies, é lenta e desigual, mesmo em condições favoráveis, muitas vezes devido à resistência do endocarpo lenhoso que os tornam impermeáveis a água. A maioria das espécies possui ainda a característica de não tolerar o processo de secagem a baixos teores de umidade, perdendo assim sua viabilidade. Tendo em vista essas considerações, objetivou-se avaliar o efeito de diferentes períodos de reidratação no processo germinativo de sementes de palmeira-real, tamareira anã, e jeriva. As sementes foram homogeneizadas e imersas em água contendo 3 vezes o volume das mesmas, com substituição diária. O delineamento experimental utilizado foi o inteiramente casualizado, com 5 tratamentos (0, 3, 6, 9 e 12 dias de reidratação), com 4 repetições de 25 sementes. As sementes foram colocadas em caixas de plástico tipo “gerbox” transparentes contendo como substrato vermiculita média e colocadas em BOD com fotoperíodo de 16 horas de luz e suas respectivas temperaturas ótimas para cada espécie. A contagem do número de sementes germinadas foi realizada a cada 2 dias até estabilização da germinação. As variáveis analisadas foram porcentagem de germinação, índice de velocidade de germinação (IVG), tempo médio de germinação (TMG) e distribuição da germinação ao longo dos dias. A reidratação por 3 dias aumentou a taxa de germinação de sementes de palmeira-real. Para as espécies tamareira anã e jeriva a reidratação não influenciou nas variáveis analisadas. O IVG e TMG foram influenciados negativamente pelos períodos de reidratação para palmeira-real. A reidratação prolongou o pico de germinação das espécies estudadas.

Abstract Palm seeds are indicative of being recalcitrant species. Seeds germination for many species, is slow and uneven, even in favorable conditions, often due to the resistance of the woody endocarp that makes them impermeable to water. Most species also have the characteristic of not tolerating the drying process at low moisture levels, thus losing their viability. In view of these considerations, the objective was to evaluate the effect of different periods of rehydration on the germinative process of seeds of royal palm, dwarf palm and jeriva. Seeds were homogenized and immersed in water containing 3 times their volume, with daily replacement. The experimental design used was completely randomized, with 5 treatments (0, 3, 6, 9, and 12 days of rehydration), with 4 replications of 25 seeds. The seeds were placed in transparent “gerbox” plastic boxes containing medium vermiculite as substrate and placed in BOD with a photoperiod of 16-hour of light and their respective optimum temperatures for each species. The number of germinated seeds was counted every 2 days until germination stabilized. The variables analyzed were germination percentage, germination speed index (GSI), average germination time (AGT) and distribution of germination over the days. Rehydration for 3 days increased the germination rate of royal palm seeds. For dwarf and jeriva species, rehydration did not influence the analyzed variables. The GSI and AGT were negatively influenced by the rehydration periods for royal palm. Rehydration prolonged the peak of germination of the studied species.

Abstract Background: Congenital heart disease in adults shares some features with heart failure (HF), including exercise intolerance, ventilatory inefficiency, inflammatory and neurohormonal activation, cardiac arrhythmias and myocardial fibrosis. Over the last years, cardiopulmonary exercise test has gained importance in the diagnostic and prognostic evaluation of congenital heart diseases, as has already occurred in HF. Objective: To describe the behavior of hemodynamic, metabolic and ventilatory parameters in response to exercise in adults with congenital heart disease. Methods: Observational cross-sectional study evaluating 31 adults with congenital acyanotic or cyanotic heart disease, treated clinically, surgically or percutaneously, referred for cardiopulmonary exercise test. A descriptive analysis of the data was performed. Results: Patients aged 35.7 ± 14.2 years were included. Oxygen consumption (VO2) was 44.86 ± 18.01% of predicted at peak exercise and 36.92 ± 12.93% of predicted maximal VO2 at anaerobic threshold. We found an oxygen uptake efficiency slope (OUES) of 1.49 ± 0.89 (61.43 ± 26.63% of predicted), oxygen pulse of 58.90 ± 22.24% and increment in systolic arterial pressure during exercise was 31.42 ± 21.60 mmHg. Conclusion: Adults with congenital heart disease had similar responses to heart failure patients during exercise - reduced aerobic capacity, ventilatory inefficiency for oxygen consumption and limited inotropic response to exercise, characterized by reduced oxygen pulse and small increase in systolic arterial pressure.

RESUMO Objetivo: Avaliar os efeitos da compressão torácica manual (CTM) sobre o flow bias expiratório durante a manobra positive end-expiratory pressure-zero end-expiratory pressure (PEEP-ZEEP) para a remoção de secreção em pacientes sob ventilação mecânica invasiva. O flow bias, que influencia na remoção de secreção pulmonar, foi avaliado pela razão e diferença entre pico de fluxo expiratório (PFE) e pico de fluxo inspiratório (PFI). Métodos: Estudo cruzado e randomizado no qual participaram 10 pacientes. A manobra PEEP-ZEEP foi aplicada em quatro momentos, sendo um sem CTM e os outros três em associação com a CTM, que foram aplicadas por três fisioterapeutas distintos. Um monitor específico foi utilizado para o registro dos dados de mecânica respiratória. Resultados: A manobra PEEP-ZEEP sem a CTM foi suficiente para ultrapassar o limiar do flow bias expiratório (diferença PFE − PFI > 33 l/min), considerado necessário para deslocar a secreção em direção à glote; a média da diferença PFE − PFI encontrada foi de 49,1 ± 9,4 l/min. A média da razão PFE/PFI alcançada foi de 3,3 ± 0,7. A associação da CTM à PEEP-ZEEP aumentou a média da diferença PFE − PFI em 6,7 ± 3,4 l/min. Foi observada correlação moderada entre a força de preensão manual dos fisioterapeutas e o flow bias gerado durante a CTM. Não foram encontradas alterações hemodinâmicas ou respiratórias adversas ao longo do estudo. Conclusões: A manobra PEEP-ZEEP sem a CTM resultou em um flow bias expiratório superior ao considerado efetivo para auxiliar na remoção de secreção pulmonar. A associação com a CTM aumentou o flow bias expiratório, o que aumenta o potencial da manobra para remover secreções.

ABSTRACT Objective: To investigate the effects of manual chest compression (MCC) on the expiratory flow bias during the positive end-expiratory pressure-zero end-expiratory pressure (PEEP-ZEEP) airway clearance maneuver applied in patients on mechanical ventilation. The flow bias, which influences pulmonary secretion removal, is evaluated by the ratio and difference between the peak expiratory flow (PEF) and the peak inspiratory flow (PIF). Methods: This was a crossover randomized study involving 10 patients. The PEEP-ZEEP maneuver was applied at four time points, one without MCC and the other three with MCC, which were performed by three different respiratory therapists. Respiratory mechanics data were obtained with a specific monitor. Results: The PEEP-ZEEP maneuver without MCC was enough to exceed the threshold that is considered necessary to move secretion toward the glottis (PEF − PIF difference > 33 L/min): a mean PEF − PIF difference of 49.1 ± 9.4 L/min was achieved. The mean PEF/PIF ratio achieved was 3.3 ± 0.7. Using MCC with PEEP-ZEEP increased the mean PEF − PIF difference by 6.7 ± 3.4 L/min. We found a moderate correlation between respiratory therapist hand grip strength and the flow bias generated with MCC. No adverse hemodynamic or respiratory effects were found. Conclusions: The PEEP-ZEEP maneuver, without MCC, resulted in an expiratory flow bias superior to that necessary to facilitate pulmonary secretion removal. Combining MCC with the PEEP-ZEEP maneuver increased the expiratory flow bias, which increases the potential of the maneuver to remove secretions.

RESUMO A aplicação de técnicas moleculares para lidar com questões ecológicas e evolutivas requer DNA genômico de boa qualidade e quantidade. A qualidade do DNA isolado, no entanto, pode ser influenciada pelo tipo de tecido e pela maneira como a amostra foi conservada e manipulada. Portanto, personalizar protocolos para melhorar o isolamento do DNA e a amplificação dos locus é crucial. Nós otimizamos um protocolo barato e manual de extração de DNA e amplificação de microssatélites utilizando cinco diferentes tecidos de uma espécie de palmeira da Mata Atlântica brasileira. Nós extraímos com sucesso o DNA de todos os cinco tipos de tecidos. Folha, caule e endocarpo de sementes não dispersas apresentaram as maiores taxas de extração de DNA e amplificação de microssatélites; enquanto raiz, endocarpo de sementes dispersas e embrião apresentaram a menor qualidade e quantidade. Com base nesses resultados, discutimos as implicações do uso de diferentes tecidos para estudos sobre dispersão de sementes, polinização e genética de populações.

ABSTRACT The application of molecular techniques to tackle ecological and evolutionary questions requires genomic DNA in good quality and quantity. The quality of the isolated DNA, however, can be influenced by the tissue type and the way the sample was conserved and manipulated. Therefore, customizing protocols to improve the DNA isolation and locus amplification is crucial. We optimized a cheap and manual protocol of DNA extraction and microsatellites amplification using five different tissues of a palm species of the brazilian Atlantic Forest. We successfully extracted DNA from all five tissue types. Leaf, stem, and endocarp of non-dispersed seeds presented the highest rates of successful DNA extraction and microsatellite amplification; whereas root, endocarp of dispersed seeds, and embryo showed the lowest quality and quantity. Based on these results, we discussed the implications of using different tissues for studies about seed dispersal, pollination, and population genetics.

AbstractThis paper reports a study aimed to assess whether passengers would change the road transport -- whether individual transport (IT) or passenger bus transport (BT) -- for the rail transport to reach or leave the International Airport Tancredo Neves in Confins, State of Minas Gerais, Brazil. It also sought to identify the passengers’ preference between the two transport modes. The study was built on two techniques: a questionnaire-based survey that approached 296 passengers, and a stated preference survey, which was answered by 223 of them. The results pointed out that most of the respondents were keen on changing the IT and BT for rail transport to reach and leave the airport. The rail transport had a good level of acceptance (84%), which, was, however, contradicted by the stated preference results: 73% of the respondents stated they do prefer the individual transport. One of the possible reasons for the controversial results may be the way the data was collected and arranged in this study. The conclusion of the study was that the rail transport enjoyed good acceptance amongst the respondents when imagined in a static scenario.

O objetivo deste estudo foi avaliar a resistência de união à dentina de uma resina utilizada para reforço de raiz, ativada com diferentes fontes de luz. De acordo com a fonte de luz utilizada as raízes foram divididas em 4 grupos (n = 15): GI, raízes não fragilizadas (controle); GII, luz halógena (H) 600 mW/cm2; GIII, LED 800 mW/cm2 e GIV, LED 1500 mW/cm2. O reforço foi feito com adesivo, resina composta e pino de fibra de vidro. Após 24 h, os espécimes foram seccionados e o primeiro slice de cada região utilizado para o teste de união push out, na máquina de ensaios universais com 0,5 mm/min, e o tipo da falha avaliada. Os dados obtidos (MPa) foram analisados utilizando os testes de ANOVA e Holm-Sidak (=0.05). O segundo slice de cada região foi analisado por microscopia eletrônica de varredura (MEV). O LED-1500 (4.69 ± 1.74) proporcionou resistência a união similar ao controle (5.05 ± 2.63) e estatisticamente diferente do H-600 (1.96 ± 0.94) e LED-800 (2.75 ± 1.90), que são similares entre si (p<0.05). As regiões cervical (4.16 ± 2.32) e média (4.43 ± 2.32) apresentaram alta resistência à união quando comparadas à região apical (2.25 ± 1.50) (p<0.05). Houve uma predominância de falhas adesivas com as fontes de luzes H-600 e LED-800 e coesivas com o LED-1500. A análise em MEV demonstrou a formação de longos tags resinosos. Desta forma, pode-se concluir que o LED-1500 proporcionou maior resistência à resina utilizada para o reforço da dentina radicular.

The aim of this study was to evaluate the bond strength to the dentin of an adhesive material used for root reinforcement light activated with different sources. Roots were divided into 4 groups (n=15) according to the light source used to activate the resin reinforcement: GI, non-weakened roots (control); GII, halogen light (H) 600 mW/cm2; GIII, LED 800 mW/cm2 and GIV, LED 1500 mW/cm2. The reinforcement was done with adhesive, composite resin and fiberglass posts. After 24 h, the specimens were sectioned and the first slice of each post region was used in the push out test in a universal testing machine with a crosshead speed of 0.5 mm/min. Failure modes of the debonded specimens were examined. Data (MPa) were analyzed by ANOVA and Holm-Sidak test (=0.05). The second slice from each region was analyzed by scanning electron microscopy (SEM). LED-1500 (4.69 ± 1.74) provided bond strength similar to the control group (5.05 ± 2.63) and statistically different from H-600 (1.96 ± 0.94) and LED-800 (2.75 ± 1.90), which were similar to each other (p<0.05). Cervical (4.16 ± 2.32) and middle (4.43 ± 2.32) regions showed higher bond strength than the apical (2.25 ± 1.50) (p<0.05). There was a prevalence of adhesive failures in H-600 and LED-800 and cohesive failures in LED-1500. SEM showed the formation of long, numerous and fine tags. It was concluded that LED-1500 provided higher bond strength of resin reinforcement to the dentin.
