Abstract Background Pathologies involving the heart are still the main causes of death, and acute myocardial infarction (AMI) is consistently present in this index. The two-minute walk test (2MWT) is ideal for assessing the functional capacity of this patient. Objective To describe the feasibility of the 2MWT in older people after AMI. Methods This is a cross-sectional study. At hospital discharge, patients were invited to perform the 2MWT. Before starting the test, systolic blood pressure (SBP), diastolic blood pressure (DBP), peripheral oxygen saturation (SpO2), heart rate (HR) and the Double Product (DP) were checked. After checking the vital signs, the patients were accompanied by an examiner, who was positioned laterally to ensure safety and verbally encouraged during the test; after the completion of the test, all vital signs were reassessed in two moments, at the immediate end and after 20 minutes of rest. ANOVA was used for the comparison of pre and post-test and pre and recovery. A p<0.05 was considered significant. Results We evaluated 51 patients, 4 (80%) males with a mean age of 67±8 years. The distance walked on the 2MWT had a mean of 157 ± 22 meters. The SBPmmHg Pre-Test 112±21 vs 131±15 Post-Test (p=0.24) and 119±22 at Recovery (p = 0.34) and HR (bpm) Pre-Test 75±15 vs 89±19 Post-Test (p=0.15) and 79±15 at Recovery (p = 0.59). After a rest, all variables analyzed followed the same pattern, returning to values close to the pre-test moment. Conclusion The performance of the 2MWT in the hospital environment presents good feasibility in the evaluation of submaximal capacity in elderly patients after AMI. death AMI (AMI index twominute minute MWT (2MWT patient crosssectional cross sectional study discharge SBP, SBP , (SBP) DBP, DBP (DBP) SpO2, SpO2 SpO (SpO2) (HR DP (DP checked examiner moments 2 rest posttest post recovery p005 p 0 05 p<0.0 significant 5 80% 80 (80% 678 67 8 67± years 15 meters PreTest Pre Test 11221 112 21 112±2 13115 131 131±1 PostTest Post p=0.24 p024 24 (p=0.24 11922 119 119±2 0.34 034 34 bpm (bpm 7515 75 75±1 8919 89 19 89±1 p=0.15 p015 (p=0.15 7915 79 79±1 0.59. 059 0.59 . 59 0.59) pattern pretest moment (SBP (DBP (SpO2 p00 p<0.

N,N-Dimethyltryptamine (DMT) is a serotonergic psychedelic that, when combined with monoamine oxidase enzyme inhibitors in the hallucinogenic beverage commonly known as ayahuasca, surpasses most common orally administered psychoactive drugs. There is a growing interest in the therapeutic potential of DMT due to recent clinical data showing the improvement of cognitive deficits associated with depression and Alzheimer’s disease. The development of analytical methodology for the monitoring of concentrations of DMT molecules to control the appropriate dosage for their use is essential for the treatment of patients. For this, we propose a novel flexible inkjet-printed paper substrate based on Au nanostars as proof of concept for DMT detection by surface-enhanced Raman scattering (SERS). The substrate was applied to detect DMT in water as a first approach to more complex matrices like ayahuasca beverages or blood samples. The optimization and performance of SERS substrates with different print cycles indicate that one print is enough to achieve the great performance of the flexible paper substrates. The SERS analyses for DMT in different concentrations, 10-3 to 10-10 mol L-1, reveal a high sensitivity of the sensors with a silhouette coefficient of 0.84 obtained by principal component analysis (PCA) statistical projections.

ABSTRACT Seasonal Forests (FE) occurring in the Cerrado, are characterized by the presence of tree species with different deciduous levels on dry seasons and vary in floristic composition depending on their geographic location. The present work has as premise that the floristic-structural patterns of these forests can be remarkable, due to the environmental conditions imposed by the environments and proximity to different watersheds. We used sample data of 17 fragments of Semideciduous Seasonal Forest (FE) in the Cerrado. For each sampling site to be inventoried an area of one hectare where the circunference of all the trees were measured at 1.30cm ≥ 15cm were included. An Principal Component Analysis - PCA, including abiotic and structural variables of each forest were made. For similarity analysis we used the floristic data in an absence-presence matrix of species and a number of trees of each species data. To determine floristic patters we use the Sorensen and Bray-Curtis similarity and made a cluster with the Unweighted Average Grouping Method (UPGMA). To explore the patterns of abundance performed in the Non-Metric multidimensional Scale (nMDS). The floristic-structural patterns indicated the presence of two distinct floristic groups, a smaller group formed different areas of the Araguaia and Paraguay River watersheds, and another large group formed by areas of the Paraná basin, and other others, even basin, more dissimilar than too much. The formation of floristic groups reflects that, as analyzed communities, there are several generalist species that are not very demanding and that adapt to new conditions, occurring in non-Cerrado and Atlantic Forest seasonal forest areas, forming two diverse tests located mainly in the Araguaia basin and Paraná.

RESUMO As Florestas Estacionais Sazonalmente Secas (FESS) ocorrentes no Cerrado são caracterizadas pela presença de espécies arbóreas com diferentes níveis de caducifólia nos períodos de estação seca e variam na composição florística dependendo da sua localização geográfica. O presente trabalho tem como objetivo assumir que os padrões florístico-estruturais destas florestas podem ser marcantes, devido às condições ambientais impostas nos ambientes e proximidade com bacias hidrográficas distintas. Foram utilizados levantamentos fitossociológicos realizados em um hectare para 17 fragmentos de Floresta Estacional Semidecidual (FES), onde aferiu-se todos os indivíduos arbóreos a circunferência a altura do peito (CAP) de 1,30cm ≥ 15cm. A avaliação foi feita por meio de uma ordenação por Análise de Componente Principal incluindo variáveis abióticas e estruturais de cada floresta. Para análise de similaridade, foram utilizados dados florísticos em uma matriz de presença-ausência utilizando os dados de ocorrência das espécies identificadas em cada localidade. Para determinar as semelhanças, utilizou-se o coeficiente de similaridade de Sorensen, o índice de Bray-Curtis e o método de agrupamento das médias não ponderadas (UPGMA). Para explorar padrões de abundância, foi feito o Escalonamento Multidimensional Não Métrico (nMDS). Os padrões florísticos-estruturais apontaram a presença de dois grupos florísticos distintos, um menor grupo formando diferentes áreas das bacias hidrográficas do Rio Araguaia e Rio Paraguai, e outro grande grupo formado por áreas da bacia do Paraná, e outras desta mesma bacia, porém mais dissimilares do que as demais. A formação de grupos florísticos reflete que as comunidades analisadas possuem diversas espécies generalistas, pouco exigentes e que se adaptam bem a novas condições, com ocorrência para áreas de florestas estacionais no Cerrado e Mata Atlântica, formando duas províncias distintas situadas, sobretudo na bacia do Araguaia e Paraná.

Abstract Objective To analyze the follow-up, in specialized outpatient clinics, of infants reported with congenital syphilis during the penicillin shortage. Method A cross-sectional study was carried out in ten public maternity hospitals affiliated with the Brazilian Unified Health System in the city of Fortaleza, state of Ceará. Clinical records of infants reported with congenital syphilis who were born alive in 2015 were used to describe correlates of attendance at recommended clinical follow-up appointments. Results A total of 469 infants reported with CS from January 1/2015 to December 31/2015 were included in the analysis. The results show that most infants did not attend the follow-up visits (368/469, 78.5%) and the main associated factors are that the follow-up clinic is located in a different hospital from that where the infant was born (OR: 3.7; CI: 2.20-6.22; p< 0.001) and the use of illicit drugs by the mother (OR: 3.2; CI: 1.57-6.87; p= 0.002). Only 33.7% (34/101) were followed until discharge. Conclusion The majority of infants with reported congenital syphilis during this period did not attend the follow-up visits. Public health efforts aimed at reaching the parents of infants with CS should be a priority to ensure appropriate clinical identification and management of the associated outcomes of this vertically transmitted infection. followup, followup follow up, up clinics shortage crosssectional cross sectional Fortaleza Ceará 201 appointments 46 12015 1 1/201 312015 31 31/201 analysis 368/469, 368469 368 (368/469 78.5% 785 78 5 OR (OR 3.7 37 3 7 CI 2.206.22 220622 2.20 6.22 2 20 6 22 2.20-6.22 p 0.001 0001 0 001 3.2 32 1.576.87 157687 1.57 6.87 57 87 1.57-6.87 0.002. 0002 0.002 . 002 0.002) 337 33 33.7 34/101 34101 34 101 (34/101 discharge infection 4 1201 1/20 31201 31/20 368/469 36846 36 (368/46 78.5 3. 206 2.206.2 22062 220 2.2 622 6.2 2.20-6.2 0.00 000 00 576 1.576.8 15768 157 1.5 687 6.8 8 1.57-6.8 33. 34/10 3410 10 (34/10 120 1/2 3120 31/2 368/46 3684 (368/4 78. 2.206. 2206 2. 62 6. 2.20-6. 0.0 1.576. 1576 15 1. 68 1.57-6. 34/1 341 (34/1 12 1/ 312 31/ 368/4 (368/ 2.206 2.20-6 0. 1.576 1.57-6 34/ (34/ 368/ (368 2.20- 1.57- (34 (36 (3 (

This work describes a green synthesis, the characterization, and biological evaluation of silver nanoparticles (AgNPs). The AgNPs suspension was synthesized using aqueous leaf extract of Eucalyptus grandis, which presented a characteristic band at 407 nm in the UV-Vis spectrum. The AgNPs presented a spherical shape and size of 9.7 ± 0.3 nm. The nanoparticles were stable over a month, indicating that E. grandis’ extract is suitable for their preparation and stabilization. The X-ray analysis showed that the crystallinity of AgNPs corresponded to the centered face phase of silver. The antibacterial and leishmanicidal activities of AgNPs were evaluated. The AgNPs presented antibacterial activity on the Gram-negative bacteria Escherichia coli at 53.9 µg mL-1. The leishmanicidal activity evaluation against promastigote forms of Leishmania infantum, Leishmania amazonensis, and Leishmania braziliensis showed that the biological response is dependent on the volume of AgNP suspension. It was demonstrated that L. infantum was more sensitive to the nanoparticle’s treatment than L. amazonensis and L. braziliensis. The treatment of L infantum promastigotes with 150 µL of AgNP suspension reduced parasite growth by 67.9%, a result which was similar to the treatment with 1 (66.7%) or 2 µL (70.6%) of amphotericin B used as a positive control. synthesis characterization AgNPs. .

Abstract The article discusses to what extent sociological theories produced in the Brazilian academic field dialogue with a global intellectual movement criticizing coloniality and the Eurocentric foundations of the social sciences. Initially, we analyze the challenges regarding the attempts to define two theoretical approaches, Brazilian sociology, and Postcolonial Thought, without overlooking their internal heterogeneities. Then, we address the tensions between these approaches as conditions for research agendas that bring both contributions into proximity. Finally, we explore the epistemological potential of one of these agendas, which corresponds to a rereading of Brazilian sociological theory in light of postcolonial criticism. This exercise in rereading the canon is based on the methodological program of sociological reduction of Guerreiro Ramos, which indicates a reciprocal interrogation between Brazilian sociology and postcolonial thought, i.e., a decentered look at our sociological tradition that also reveals contributions from this tradition for the future of postcolonial epistemologies. sciences Initially Thought heterogeneities Then proximity Finally criticism Ramos thought ie i e i.e. epistemologies i.e

Resumo O artigo discute em que medida teorias sociológicas produzidas no campo acadêmico brasileiro dialogam com um movimento global de crítica à colonialidade e aos fundamentos eurocêntricos das ciências sociais. De início, tratamos dos desafios subjacentes às tentativas de definir os dois enquadramentos, sociologia brasileira e pensamento pós-colonial, sem ignorar suas heterogeneidades internas. Em seguida, analisamos as convergências e tensões entre esses campos como condições de possibilidade para agendas de pesquisa que aproximem ambos os aportes. Por fim, exploramos o potencial epistemológico de uma dessas agendas, que corresponde a uma releitura da tradição sociológica brasileira à luz da crítica pós-colonial. Esse exercício é feito a partir do projeto da “redução sociológica”, de Guerreiro Ramos, que indica uma via de mão dupla na interlocução entre sociologia brasileira e pensamento pós-colonial: um olhar descentrado sobre nossa tradição sociológica que revela contribuições dessa tradição para o futuro das epistemologias pós-coloniais. sociais início enquadramentos póscolonial, póscolonial pós colonial, colonial pós-colonial internas seguida aportes fim póscolonial. colonial. redução sociológica, , sociológica” Ramos póscoloniais. póscoloniais coloniais. coloniais pós-coloniais

Abstract Objective To compare the level of quality of life and satisfaction after two years of total knee arthroplasties between individuals above and below 65 years of age and to identify predictor factors of poor clinical outcome and low level of satisfaction in patients undergoing arthroplasty. Methods This is a retrospective cohort with data from patients diagnosed with knee osteoarthritis submitted to primary total knee arthroplasty from 2014 to 2018 (n= 190). Clinical outcomes were assessed using the following scores: visual analog scale (VAS) of pain, EQ-5D-3L and EUROQOL-VAS (quality of life scales), patient satisfaction level, and functional scale of the Knee Injury and Osteoarthritis Outcome Score (KOOS), collected through a questionnaire applied preoperatively, as well as 1, 3, 12 and 24 months after surgery. Results Patients < 65 years old presented significantly lower values (clinical worsening) in KOOS-pain and KOOS-symptoms. There are no differences in the principal clinical scores that assess pain, function, and quality of life after the procedure, as well as in the rate of satisfaction with the procedure, among patients < 65 years old when compared with patients ≥ 65 years old. It was also observed that patients who were not satisfied with the procedure in the 24-month evaluation presented clinical results in some analyzed scores (KOOS-pain and EQ-VAS) similar to patients who declared themselves satisfied. Conclusion Scores that assess pain, function, quality of life, as well as satisfaction rate are similar between patients < 65 years old and those ≥ 65 years old. 6 201 n= n (n 190. 190 . 190) VAS (VAS pain EQ5D3L EQDL EQ 5D 3L D L EUROQOLVAS EUROQOL scales, scales , scales) KOOS, KOOS (KOOS) preoperatively 1 3 2 surgery worsening KOOSpain KOOSsymptoms.

ABSTRACT This work sought to develop a tool that would help managers of small municipalities to optimize costs. As a sample, small municipalities, with up to 30,000 inhabitants, participants of the National Sanitation Information System (Sistema Nacional de Informações sobre Saneamento – SNIS) which, according to the SNIS, are the ones that have the greatest difficulty in covering their costs with the provision of solid waste management service. Based on statistical analysis and multiple linear regression, a mathematical model was proposed to determine the cost of collection for these municipalities, considering the residential urban solid waste management: provision by direct administration, direct administration by outsourced services without a consortium and outsourcing with consortium for the models.. The variables considered were the distance to the final disposal site and the per capita generation of RSDU provided by the SNIS. The results showed that it is possible to find a collection cost model for municipalities whose provision is made by the direct administration, outsourcing the service, considering the distance to the disposal site. For municipalities that carry out collection by an intermunicipal consortium, the model considers, in addition to the final disposal distance, the per capita generation of municipal solid waste. Finally, it was not possible to arrive at a model for municipalities whose responsibility for the service is exclusive to the direct municipal administration, because few municipalities have adopted this service delivery model and their data present a very large dispersion. sample 30000 30 000 30,00 inhabitants Sistema SNIS which regression models models. considers Finally dispersion 3000 3 00 30,0 300 0 30,

RESUMO Este trabalho buscou desenvolver uma ferramenta que auxiliasse os gestores de pequenos municípios brasileiros a otimizarem os custos. Para isso, foram utilizados municípios de pequeno porte, com até 30 mil habitantes, participantes do Sistema Nacional de Informações sobre Saneamento (SNIS), os quais, de acordo com o SNIS, são os que possuem maior dificuldade para cobrir os seus custos com a prestação de serviço de manejo dos resíduos sólidos. Por análise estatística e regressão linear múltipla, buscou-se propor um modelo matemático para determinar o custo de coleta para esses municípios, considerando o gerenciamento de resíduos sólidos urbanos domiciliares (RSUD): prestação por administração direta, administração direta por serviços terceirizados sem consórcio e terceirização com consórcio para os modelos. As variáveis consideradas foram a distância até o local de disposição final e a geração per capita de RSDU fornecidos pelo SNIS. Os resultados mostraram que é possível encontrar um modelo de custo de coleta para municípios cuja prestação é feita pela administração direta terceirizando o serviço, levando-se em conta a distância até o local de disposição. Para municípios que realizam a coleta por consórcio intermunicipal, o modelo pondera, além da distância de disposição final, a geração per capita de resíduos sólidos municipais. Por fim, não se pôde chegar a um modelo para municípios cuja responsabilidade pelo serviço é exclusiva da administração direta municipal, por poucos municípios adotarem esse modelo de prestação de serviço e seus dados apresentarem dispersão muito grande. isso porte 3 habitantes SNIS , (SNIS) quais múltipla buscouse RSUD (RSUD) modelos levandose levando intermunicipal pondera municipais fim municipal grande (SNIS (RSUD

Abstract The early ontogeny of Triportheus albus and T. angulatus, two fish species of Triportheidae, is described using morphological, meristic, and morphometric characters. These species are exploited by subsistence fisheries and have potential as an alternative source of fish, given the decline in the natural stocks of other commercially important fish species in the Amazon. The specimens were collected in the open water limnetic zone, under of the macrophyte stands, and in subsurface areas near sandbars in the Amazon basin. Intra and interspecific morphometric analyzes were performed to evaluate growth models between species. The combination of color pattern, body morphology, morphometric proportions and myomeres number distinguishes the species from each other and from other congeners. Some morphometric relationships related to head as snout length and eye diameter as well as length from the snout to the origins of anal and length from the snout to the origins of pelvic, related with standard length were different between the two species of Triportheus, reflecting different growth models between them. An identification key for larvae and juveniles of some species of Triportheus from the Eastern Amazon is presented. T angulatus Triportheidae morphological meristic characters zone stands basin pattern morphology congeners pelvic them presented

Resumo A ontogenia inicial de Triportheus albus e T. angulatus, duas espécies de peixes pertencentes a Triportheidae, é descrita usando caracteres morfológicos, merísticos e morfométricos. Essas espécies são exploradas pela pesca de subsistência e têm potencial como fonte alternativa de pescado, dado o declínio nos estoques naturais de outras espécies de peixes comercialmente importantes na Amazônia. Os espécimes foram coletados na zona limnética de águas abertas, sob bancos de macrófitas e em áreas subsuperficiais próximas a bancos de areia na bacia amazônica. Análises morfométricas, intra e interespecíficas, foram realizadas para avaliar modelos de crescimento entre as espécies. A combinação do padrão de coloração, morfologia corporal, proporções morfométricas e número de miômeros distingue as espécies entre si e de outras congêneres. Algumas relações morfométricas relacionadas à cabeça, como comprimento do focinho e diâmetro do olho, assim como o comprimento do focinho à origem da nadadeira anal e o comprimento do focinho à origem da nadadeira pélvica, relacionadas ao comprimento padrão foram diferentes entre as duas espécies de Triportheus, refletindo modelos distintos de crescimento entre elas. Uma chave de identificação para larvas e juvenis de algumas espécies de Triportheus da Amazônia Oriental é apresentada.

Aim To analyze the accuracy of extraoral systems (Ceramill Map400+, AutoScan-DS200+, and E2) in full implant-prosthetic rehabilitation three-dimensionally. Methods A metallic edentulous maxilla with four implants was digitalized by a contact scanner (MDX-40 - Roland, control) and used as a control image to compare with other images generated by three laboratory scanners (10 samples per group). Letters identified all the four components: A and D angled 45º, and B and C parallel. The BioCAD software exported the images (.STL) to compare and verify deviations of the analogs on the X, Y, and Z axes. The nonparametric Kruskal-Wallis test and the two-way ANOVA on ranks with a post hoc Tukey test analyzed the data with 5% significance. Results No statistical differences were observed in the accuracy between the extraoral scanners (p=0.0806). However, when analyzing only the components, component D was more accurate when scanned with Ceramill Map400+ compared with AutoScan DS200+ (p<0.001) and with E2 (p=0.002). Conclusions All extraoral systems assessed showed digitalization accuracy but with more deviations in angled implants. The Ceramill Map400+ scanner showed the best results for the digital impression of a complete arch.

RESUMO A compactação modifica o arranjo estrutural e as funções essenciais dos poros do solo. O trabalho teve como objetivo avaliar o impacto de diferentes graus de compactação em um Argissolo Amarelo sobre os atributos físicos-hídricos indicadores da funcionalidade dos poros. Foram utilizados cilindros de solo 0.05 x 0.05 m em 4 graus de compactação (GC): 61, 71, 82 e 92%, e em cada GC, foi quantificado, sob um delineamento inteiramente aleatorizado, a distribuição de poros por tamanho, permeabilidade intrínseca do solo ao ar (Kar), índice N de continuidade de poros, curva caraterística da água no solo e frequência acumulada de poros. O incremento no GC não causou impacto na quantidade de microporos, mas diminuiu a quantidade de macroporos para valores menores que o mínimo requerido a partir do GC de 82%. O aumento no CG provocou redução no índice N, Kar e porosidade de aeração, porém com amplitude diferente dependendo do GC e da tensão da água no solo. Os GC acima de 61% reduziram o conteúdo de água na faixa de tensão entre 0 até 6 kPa e, como consequência, aumentaram a porcentagem de poros de areação; enquanto na faixa entre 10 e 1500 kPa proporcionaram maior retenção de água. A avaliação dos atributos físicos-hídricos do Argissolo Amarelo revelou que o incremento na compactação alterou a estrutura do solo, reduziu e formou poros pouco contínuos, e menos permeável ao fluxo de ar; e apesar da maior retenção de água nas tensões mais elevadas, promoveu menor conteúdo de umidade disponível.

ABSTRACT Compaction modifies the structural arrangement and essential functions of soil pores. In this context, the objective of this study was to evaluate the impact of different compaction levels in an Argissolo Amarelo (Ultisol) on the physical-hydraulic attributes that indicate the functionality of soil pores. The experiment was conducted using 0.05 x 0.05 m soil cylinders with 4 compaction levels (CL): 61, 71, 82 and 92%, and at each CL, the pore-size distribution, intrinsic soil air permeability (Kair), pore continuity index N, soil water characteristic curve and cumulative pore-size frequency were quantified under a completely randomized design. The increase in CL did not impact the amount of micropores, but reduced the amount of macropores to values lower than the minimum required from the CL of 82%. The increase in CL caused reductions in N index, Kair and aeration porosity, but with different amplitude depending on the CL and the water tension in the soil. CL above 61% reduced the water content at the tension range between 0 and 6 kPa and, as a consequence, increased the percentage of aeration pores, besides promoting greater water retention within the range between 10 and 1500 kPa. The evaluation of the physical-hydraulic attributes of the Argissolo Amarelo (Ultisol) revealed that the increase in the compaction level altered soil structure, reduced and formed pores that were poorly continuous and less permeable to air flow and, despite the higher water retention at the higher tensions, promoted lower available moisture content.
