ABSTRACT In the Cerrado, the palm swamps ( veredas ) are characterized by being humid and stable environments that lead to the formation of Histosols ( Organossolos ). and soils with surface horizons of organic constitution, which are fragile and sensitive to anthropic action. This study aimed to evaluate the impact of anthropization (recurrent forest fires and livestock farming) on the chemical, physical and morphological properties of soils in two palm swamps in the Environmental Preservation Area (EPA) of Pandeiros River, Minas Gerais, namely: Água Doce, in preserved condition, and Taboa, in anthropized condition. Four soil profiles were morphologically described, two profiles in each palm swamp, with subsequent chemical and physical analyses, calculations of organic carbon stock and identification of the origin of organic matter. The results were analyzed using descriptive statistics and Pearson’s correlation coefficient. Soil morphological properties were influenced by vegetation cover, drainage and anthropization conditions. As for the physical and chemical properties, adequate values were observed in the preserved palm swamp, including lower bulk density values and higher cation contents. Anthropic actions in the anthropized palm swamp caused degradation of soils, revealed by subsidence, reduction in organic carbon content, increase in bulk density and decrease in fertility. Changes promoted in the soils of the palm swamps compromise ecosystem services, indicating that actions at either local or governmental level should be stimulated for the preservation and conservation of these environments.

PROCESSING OF SPENT ULTRA-DEEP HYDRODESULFURIZATION CATALYSTS. This work discusses the recycling of spent NiMo/Al2O3 catalysts from ultra-deep hydrodesulfurization (HDS) units. They contain a refractory coke and fouling elements from the processed feedstocks. Samples were preoxidized (600 ºC) for 12 h using a very slow heating rate to eliminate coke and volatiles. Experiments were performed in the presence of HF + H2O2 mixtures under stirring at 25-60oC for 1-4 h. The amount of insoluble matter was the lowest (< 1 wt.% of the initial mass) after leaching for 2 h at 60oC using an excess of 50 vol.% HF and 20 vol.% H2O2. Leached molybdenum and vanadium were extracted together with Alamine 304 (tri-dodecylamine) in n-heptane at pH below 2. Aluminum and iron were precipitated from the raffinate as Na3AℓF6 (+ Na3FeF6) by adjusting pH at ~4 using 6 mol L-1 NaOH. Nickel was either recovered by solvent extraction using D2EHPA (bis-(2-ethylhexyl)phosphoric acid) in n-heptane at pH 6 or precipitated at pH 8 using 6 mol L-1 NaOH. The first method proved better as less contaminants were present. After slow evaporation of the final aqueous solution, a mixture of Na2SiF6 and NaF was recovered. Fluoride losses were very low (~0.10 wt.%).

Resumo O objetivo deste trabalho foi determinar as temperaturas basais, as necessidades térmicas e a duração dos principais estádios fenológicos reprodutivos do açaizeiro (Euterpe oleracea) no Nordeste do estado do Pará, na Amazônia Oriental, Brasil. O experimento foi realizado de 2017 a 2019, em plantio de açaizeiro de 10 ha, tendo-se utilizado análise de série temporal. A fenologia das plantas foi monitorada semanalmente, e as condições meteorológicas dos locais foram monitoradas diariamente. As temperaturas basais inferiores e superiores foram de 12,92 e 32,46°C, respectivamente, na prefloração; 13,50 e 32,23°C na floração; 12,14 e 32,55°C no estádio de frutos verdes; 11,64 e 32,78°C no estádio de mudança de cor dos frutos; e 11,23 e 32,94°C na maturação. A exigência térmica e a duração média para o ponto ideal de colheita do açaí foram de 3.893,15 graus-dias e 283 dias, respectivamente. A exigência térmica e a duração dos estádios da fase reprodutiva do açaizeiro são influenciadas pelo período do ano e pela variabilidade da temperatura do ar, que, quando elevada, reduz o ciclo da cultura, e, quando amena, o estende.

Abstract The objective of this work was to deter mine the base temperatures, thermal time requirements, and length of the main reproductive growth stages of acai palm (Euterpe oleracea) in the northeast of the state of Pará, in eastern Amazon, Brazil. The experiment was carried out from 2017 to 2019 in a 10 ha acai plantation, using the time-series analysis. Plant phenology was monitored weekly, and local weather conditions were monitored daily. The lower and upper base temperatures were of 12.92 and 32.46°C, respectively, for pre-flowering; 13.50 and 32.23°C for flowering; 12.14 and 32.55°C for green fruit stage; 11.64 and 32.78°C for fruit color-changing stage; and 11.23 and 32.94°C for maturation. The thermal time requirement and the average cycle length for the ideal harvest time of acai palm were 3,893.15 degree-days and 283 days, respectively. The thermal time requirement and the duration of the reproductive growth stage for acai palm are influenced by the period of the year and the variability of air temperature, which, when high, reduces the cycle of the crop, and when mild, increases it.

ABSTRACT Background: American cutaneous leishmaniasis is a commonly neglected, vector-borne tropical parasitic disease that is a major public health concern in Brazil. Leishmania (Viannia) braziliensis is the main species associated with the disease. Accurate diagnosis is based on epidemiological surveillance, clinical assessment, and laboratory testing. Leishmania (V.) braziliensis has been detected in several wild and synanthropic mammals. Their epidemiological role has not been entirely elucidated. This study aimed to assess potential L. braziliensis infections in asymptomatic domestic animals, by molecular and serological testing in endemic areas, in the metropolitan region of Recife. Methods: Blood samples and conjunctival fluids were collected from 232 animals (canids, felids, equines, and caprines) for the detection of L. braziliensis using molecular tests (conventional and real-time polymerase chain reaction [PCR and qPCR]). For immunological detection, blood samples from 115 dogs were assessed using enzyme-linked immunosorbent assay. Results: Real-time quantitative PCR showed positive results for blood and conjunctival samples in all investigated species. The results of the blood and conjunctival samples were 68.2% and 26.9% in Canis familiaris, 100% and 41.7% in Felis catus, 77.3% and 30.8% in Equus caballus/Equus asinus, and 50% and 33.3% in Capra hircus samples, respectively. Conclusions: Results from this study adds valuable information to our understanding of the role of asymptomatic domestic animals, L. braziliensis life cycle, and American cutaneous leishmaniasis in Northeast Brazil.

Resumo: Esta pesquisa apresenta uma revisão sistematizada da literatura para identificar os principais fatores críticos de sucesso (FCS) que influenciam a competitividade de startups. Considerando que aspectos relacionados à competitividade devem ser o alvo das organizações, principalmente das empresas em estágio inicial, este artigo identifica uma ampla gama de fatores relacionados à competitividade das startups. Foram selecionados 36 artigos nas bases de dados Scopus e Web of Science e realizada análise bibliométrica aprofundada do corpus por meio do software VOSviewer. Foram identificados 25 FCS que influenciam a competitividade das startups e categorizados em três pontos de vista fundamentais (PVF), a saber: organizacional, humano e ambiental. O PVF organizacional abrange fatores que definem as características internas das startups. O PVF Humano, por sua vez, consiste em características do capital humano, enquanto o PVF Ambiental refere-se a fatores externos às startups e ao contexto em que atuam. Este trabalho pode ajudar profissionais e formuladores de políticas, esclarecendo-os sobre a competitividade das startups e os elementos envolvidos nisso, além de fornecer-lhes uma estrutura conceitual robusta.

Abstract: This research presents a systematized literature review to identify the main critical success factors (CSFs) that influence startups’ competitiveness. Considering that aspects related to competitiveness should be the target of organizations, especially early-stage companies, this paper identifies a broad of factors regarding startups’ competitiveness. A total of 36 articles were selected in Scopus and Web of Science databases and an in-depth bibliometric analysis of the corpus was performed using the VOSviewer software. 25 CSFs that influence startups’ competitiveness were identified and categorized into three fundamental points of view (FPVs), namely: organizational, human, and environmental. Organizational FPV covers factors that define the internal characteristics of startups. Human FPV, in turn, consists of characteristics of human capital, while the Environmental FPV refers to external factors and the startup context. This work could help practitioners and policymakers by enlightening them about startups’ competitiveness and the elements involved therein, along with providing them with a robust conceptual framework.

ABSTRACT This study was conducted to characterize the transmission cycle of the tegumentary leishmaniasis (TL) in an old colonization area at Pernambuco State, Brazil. The aims were to identify autochthonous cases, sandflies fauna, domestic animals as possible reservoir hosts and the Leishmania species involved in this endemic area. A total of 168 suspected human cases of TL and 272 domestic animals (canine, feline, equine, goat, and sheep) were included. The sandflies were captured and identified by species. Patients were predominantly male and the average age was 37+18.1 years old. Of 85 patients who had skin lesions, 25.6% of them had direct positive smears for TL and 34 isolates were identified as Leishmania (Viannia) braziliensis. The confirmation for TL diagnosed by molecular detection (PCR) was almost three times more sensitive than the direct test [p < 0.001; PR = 2.72] associated with clinical examination. The Kappa test on PCR between two different specimens, biopsy, and skin lesion swab was 60.8% (p < 0.001). More than 200 specimens of sandflies (80 males and 159 females) were captured and identified as Lutzomyia whitmani (99.6%) and Lu. evandroi (0.4%). The detection of L. (V.) braziliensis by Real-Time PCR in the blood of a captured fed female was positive in 59.3% of Lu. whitmani. Of the 272 domestic animals included, 61.76% were male (n = 168). Thirty-six animals (13.2%) had lesions compatible with TL (34 dogs, 1 cat and 1 sheep) and 3 of them, all dogs, had lesions on the snout, showing destruction of cartilage and mucosa. The study suggests the participation of domestic animals as possible reservoirs. However, further studies are necessary to better understand the transmission cycle and take recommended measures in order to control the disease.

ABSTRACT Background: Inflammatory bowel disease (IBD) is an immune-mediated disorder that includes Crohn’s disease (CD) and ulcerative colitis. CD is characterized by a transmural intestinal involvement from the mouth to the anus with recurrent and remitting symptoms that can lead to progressive bowel damage and disability over time. Objective: To guide the safest and effective medical treatments of adults with CD. Methods: This consensus was developed by stakeholders representing Brazilian gastroenterologists and colorectal surgeons (Brazilian Organization for Crohn's disease and Colitis (GEDIIB)). A systematic review of the most recent evidence was conducted to support the recommendations/statements. All included recommendations and statements were endorsed in a modified Delphi panel by the stakeholders and experts in IBD with an agreement of at least 80% or greater consensus rate. Results and conclusion: The medical recommendations (pharmacological and non-pharmacological interventions) were mapped according to the stage of treatment and severity of the disease in three domains: management and treatment (drug and surgical interventions), criteria for evaluating the effectiveness of medical treatment, and follow-up/patient monitoring after initial treatment. The consensus is targeted towards general practitioners, gastroenterologists, and surgeons interested in treating and managing adults with CD and supports the decision-making of health insurance companies, regulatory agencies, and health institutional leaders or administrators.

RESUMO Contexto: A doença inflamatória intestinal (DII) é uma doença imunomediada que inclui a doença de Crohn (DC) e a retocolite ulcerativa. A DC é caracterizada por um envolvimento intestinal transmural da boca ao ânus com sintomas recorrentes e remitentes que podem levar a danos intestinais progressivos e incapacidade ao longo do tempo. Objetivo: Orientar os tratamentos médicos mais seguros e eficazes de adultos com DC. Métodos: Este consenso foi desenvolvido por autores que representam gastroenterologistas e cirurgiões brasileiros especialistas em doenças colorretais (GEDIIB, Organização Brasileira de Doença de Crohn e Colite). Uma revisão sistemática das evidências mais recentes foi realizada para apoiar as recomendações/declarações. Todas as recomendações e declarações incluídas foram endossadas em um painel Delphi modificado pelas partes interessadas e especialistas em DII com uma concordância de pelo menos 80% ou mais. Resultados e conclusão: As recomendações médicas (intervenções farmacológicas e não farmacológicas) foram mapeadas de acordo com o estágio de tratamento e gravidade da doença em três domínios: manejo e tratamento (intervenções medicamentosas e cirúrgicas), critérios para avaliar a eficácia do tratamento médico, e acompanhamento/monitoramento do paciente após o tratamento inicial. O consenso é direcionado a clínicos gerais, gastroenterologistas e cirurgiões interessados em tratar e gerenciar adultos com DC e apoia a tomada de decisões de companhias de seguro de saúde, agências reguladoras e líderes ou administradores de instituições de saúde.

ABSTRACT Background: Inflammatory bowel diseases are immune-mediated disorders that include Crohn’s disease (CD) and ulcerative colitis (UC). UC is a progressive disease that affects the colorectal mucosa causing debilitating symptoms leading to high morbidity and work disability. As a consequence of chronic colonic inflammation, UC is also associated with an increased risk of colorectal cancer. Objective: This consensus aims to provide guidance on the most effective medical management of adult patients with UC. Methods: A consensus statement was developed by stakeholders representing Brazilian gastroenterologists and colorectal surgeons (Brazilian Organization for Crohn’s Disease and Colitis [GEDIIB]). A systematic review including the most recent evidence was conducted to support the recommendations and statements. All recommendations/statements were endorsed using a modified Delphi Panel by the stakeholders/experts in inflammatory bowel disease with at least 80% or greater consensus. Results and conclusion: The medical recommendations (pharmacological and non-pharmacological) were mapped according to the stage of treatment and severity of the disease onto three domains: management and treatment (drug and surgical interventions), criteria for evaluating the effectiveness of medical treatment, and follow-up/patient monitoring after initial treatment. The consensus targeted general practitioners, gastroenterologists and surgeons who manage patients with UC, and supports decision-making processes by health insurance companies, regulatory agencies, health institutional leaders, and administrators.

RESUMO Contexto: As doenças inflamatórias intestinais são doenças imunomediadas que incluem a doença de Crohn (DC) e a retocolite ulcerativa (RCU). A RCU é uma doença progressiva que acomete a mucosa colorretal causando sintomas debilitantes levando a alta morbidade e incapacidade laboral. Como consequência da inflamação crônica do cólon, a RCU também está associada a um risco aumentado de câncer colorretal. Objetivo: Este consenso visa fornecer orientações sobre o manejo médico mais eficaz de pacientes adultos com RCU. Métodos: As recomendações do consenso foram desenvolvidas por gastroenterologistas e cirurgiões colorretais referências no Brasil (membros da Organização Brasileira para Doença de Crohn e Colite [GEDIIB]). Uma revisão sistemática, incluindo as evidências mais recentes, foi conduzida para apoiar as recomendações. Todas as recomendações foram endossadas pelas partes interessadas/especialistas em doença inflamatória intestinal usando um Painel Delphi modificado. O nível de concordância para alcançar consenso foi de 80% ou mais. Resultados e conclus ão: As recomendações médicas (farmacológicas e não farmacológicas) foram mapeadas de acordo com o estágio de tratamento e gravidade da doença em três domínios: manejo e tratamento (intervenções medicamentosas e cirúrgicas), critérios para avaliar a eficácia do tratamento médico, e acompanhamento/monitoramento do paciente após o tratamento inicial. O consenso foi direcionado a clínicos gerais, gastroenterologistas e cirurgiões que tratam pacientes com RCU e apoia os processos de tomada de decisão por companhias de seguro de saúde, agências reguladoras, líderes institucionais de saúde e administradores.

ABSTRACT Objective: to evaluate the effectiveness of auriculoacupuncture in improving the sleep quality of nursing professionals in the fight against the COVID-19 pandemic. Method: quasi-experimental before and after study, without a control or matching group performed from May to July 2020, in a referral hospital for infectious diseases in Ceará. The sample consisted of 26 nursing professionals, including nurses and technicians, who performed three sessions of auriculoacupuncture, once a week, for four weeks. Sleep quality was measured by the Pittsburg Sleep Quality Index. The effects of the intervention were analyzed by the student's “t” test to compare means between the first and last application, one-way ANOVA with repeated measures and post-hoc Sidak´s test. Results: regarding the components of the Pittsburg Sleep Quality Index, significant differences were observed between the individuals in the components: subjective sleep quality (p=0.001); sleep latency (p<0.001), sleep duration (p<0.001), habitual sleep efficiency (p=0.011), sleep disorders (p<0.001), sleeping medications (p=0.005) and excessive daytime sleep sleepiness (p<0.001). The overall sleep index also changed significantly (p<0.001). The intervention reduced the sleep quality index score by 52.35%. Conclusion: the changes that occurred were able to change the category in sleep classification through a detailed decrease in the Pittsburg Sleep Quality Index scores. Significant differences were observed between the first and final moments in the global index and in all components.

RESUMEN Objetivo: evaluar la efectividad de la auriculopuntura en la mejora de la calidad del sueño de los profesionales de enfermería que trabajan para combatir la pandemia de COVID-19. Método: estudio cuasiexperimental, sin grupo control ni pareado, del tipo antes y después, desarrollado de mayo a julio de 2020, en un hospital de referencia por enfermedades infecciosas en Ceará. La muestra estuvo conformada por 26 profesionales de enfermería, entre enfermeros y técnicos, quienes realizaron tres sesiones de auriculoacupuntura, una vez por semana, durante cuatro semanas. La calidad del sueño se midió mediante el índice de calidad del sueño de Pittsburg. Los efectos de la intervención se analizaron mediante la prueba “t” de Student para comparar medias entre la primera y la última aplicación, ANOVA unidireccional con medidas repetidas y prueba post-hoc de Sidak. Resultados: con respecto a los componentes del Índice de Calidad del Sueño de Pittsburg, se encontraron diferencias significativas entre los individuos en los componentes: calidad subjetiva del sueño (p = 0,001); latencia del sueño (p <0,001), duración del sueño (p <0,001), eficiencia habitual del sueño (p = 0,011), trastornos del sueño (p <0,001), medicamentos para dormir (p = 0,005) y disfunción del sueño durante el día (p <0,001). El índice general de sueño también cambió significativamente (p <0,001). La intervención redujo la puntuación del índice de calidad del sueño en un 52,35%. Conclusión: los cambios que ocurrieron pudieron cambiar la categoría en la clasificación del sueño a través de una caída sustancial en las puntuaciones del Índice de Calidad del Sueño de Pittsburg. Se observaron diferencias significativas entre los momentos inicial y final en el índice global y en todos los componentes.

The recovery of precious and base metals of a metal concentrate from ground waste printed circuit boards (PCBs) is described in detail. Samples were treated with NaOHaq. to remove the soldering mask. Experiments were performed in acidic medium (HF, H2SO4, CH3COOH or H3PO4) using H2O2 as oxidant. Base metals were leached in high yields (>99 wt.%) at ~40 ºC after ~1 h (HF), ~2 h (H2SO4), ~4 h (H3PO4) and ~5 h (CH3COOH). Lead precipitated in the presence of H2SO4 and HF. Precious metals were not oxidized. Ceramic/fiberglass components were dissolved in the presence of HF. Silver, palladium and gold were recovered from the insoluble solid, in this order, by a sequential oxidative treatment in aqueous medium. Recovery of leached elements was possible by a combination of solvent extraction and precipitation. The choice of the extractant and the precipitant were essential to recover them with high yields. The leachates from H3PO4 + H2O2 experiments could not be processed above pH 2.5. Leaching of waste PCBs in the presence of a weak organic acid is possible but a multistage separation scheme for elements recovery is unavoidable as PCBs is a complex material in terms of composition.

Abstract: En Pt

Mental disorders can affect up to 70% of individuals with tuberculosis (TB). The World Health Organization (WHO) End TB Strategy explicitly calls for TB and mental health service integration. The goal of this study was to explore the barriers and facilitators to integrating depression treatment in the TB Control Program and primary care system in the municipality of Itaboraí - Rio de Janeiro, using Interpersonal Counseling (IPC). IPC is an evidence-based treatment for depression that can be delivered by non-mental health specialists with expert supervision. This study was conducted between 2016 and 2017 in the municipality of Itaboraí. Data collection consisted of six focus groups (n = 42) with health professionals (n = 29), program coordinators (n = 7) and TB patients (n = 6). The main potential barriers identified were poverty, political instability, an overburdened and under-resourced health system, high levels of distress among professionals, violence in the community and stigma related to mental health and TB. Potential facilitators included a high receptivity to, and demand for, mental health training; strong community relationships through the Community Health Workers (CHW); overall acceptability of IPC delivered by non-specialists for the treatment of depression among individuals with and without comorbid TB. Despite many challenges, integrating depression treatment into primary care in Itaboraí using IPC was perceived as an acceptable and feasible option.

Os transtornos mentais podem afetar até 70% dos indivíduos com tuberculose (TB). A Organização Mundial da Saúde (OMS), como estratégia para o fim da TB, exige a integração do seu tratamento com a saúde mental. O objetivo deste estudo foi explorar as barreiras e facilitadores para integrar serviços de saúde mental no Programa de Controle de Tuberculose (PCT) e em Unidades de Saúde da Família (USF) do município de Itaboraí – Rio de Janeiro, com a aplicação do Aconselhamento Interpessoal (AIP). O AIP é um tratamento para depressão baseado em evidências que pode ser aplicado por não especialistas em saúde mental com supervisão especializada. Seis grupos focais foram realizados entre 2016 e 2017 no município de Itaboraí. A amostra (n=42) incluiu profissionais de saúde (n=29), coordenadores de programas (n=7) e pacientes com TB (n=6). Os grandes desafios encontrados foram: pobreza, instabilidade política, um sistema de saúde sobrecarregado e com poucos recursos, alta frequência de estresse entre os profissionais, violência na comunidade e estigma relacionado à saúde mental e à TB. Os facilitadores potenciais incluíram uma grande receptividade e demanda para capacitações em saúde mental; boa relação com a comunidade pelos Agentes Comunitários de Saúde (ACS) e; aceitação geral do AIP aplicado por não especialistas em saúde mental para o tratamento de depressão em pessoas com e sem TB. Apesar de muitos desafios, integrar o tratamento de depressão na atenção primária de Itaboraí aplicando o AIP foi percebido como uma alternativa aceitável e factível.

ABSTRACT We conducted the genome sequencing and analysis of the first confirmed COVID-19 infections in Brazil. Rapid sequencing coupled with phylogenetic analyses in the context of travel history corroborate multiple independent importations from Italy and local spread during the initial stage of COVID-19 transmission in Brazil.

Abstract: En | Text: En | PDF: En

Abstract A comprehensive tectonic evolution of Proterozoic to Cambrian rocks that integrate the crystalline basement of Rio de Janeiro State, based on the new geological map, is presented. The map combines detailed geological data integrated to a 1:400.000 scale and new geochemical and geochronology data to characterize the distinct terranes amalgamated during three pulses of the Brasiliano orogeny. The Occidental terrane comprises the Tonian to Late Cryogenean passive margin of the São Francisco paleocontinent, including reworked cratonic basement. At the same period, two magmatic arc systems were developed outboard: The Continental Inner arc system represented by the dismembered terranes (Paraíba do Sul, Embú, and Cambuci domain) integrated now in the Central Superterrane: and the Intra-oceanic Outer Arc System, the Oriental Terrane, developed from 860 to 620 Ma. Related active basins were detected in association with the two arc systems that collided at ca. 620 - 595 and 605 - 550 Ma against the São Francisco passive margin. A later collision episode at ca. 535 to 510 Ma brought the Cabo Frio Terrane (Angola tip) and closed the Búzios back-arc basin. Finally, the collapse of the orogenic belt, probably related to slab detachment and asthenosphere upwelling marks transition to Gondwana stabilization.
