ABSTRACT Afforestation of sites disturbed after bauxite mining is the favorite technique to restore all ecosystem functions. The nature of the tree species used for revegetation of post-mining land can accelerate the recovery of soil organic matter and nutrient cycles. This study aimed to determine the litterfall production, decomposition rate and nutrient content from three types of forest cover ( Eucalyptus , Anadenanthera peregrina , mixed plantation of 16 native species) planted in a bauxite mining area in recovery. Litterfall production was evaluated monthly over 30 months, and the litter mass was assessed twice a year (dry and rainy periods). Total nutrient content was determined from samples grouped by period (dry and rainy). The annual average values for litterfall dry mass and litter mass were higher in Eucalyptus and mixed native. The period (dry or rainy) did not influence litterfall rates in A. peregrina , but Eucalyptus and mixed native presented higher amounts for litterfall during the rainy and dry periods, respectively. Litter accumulation in Eucalyptus was not affected by the season of the year, but mixed native and A. peregrina presented higher litter accumulation in the dry season. Apparent decomposition rates of A. peregrina and mixed native were higher in the rainy season, highlighting the A. peregrina with the highest values compared with the other forest covers. The mixed native presented the highest leaf content of P, K, Ca and Mg in both the litterfall and litter mass, while Eucalyptus had the lowest P, K, Ca, S and N content and the highest C content in the litterfall. Litterfall production is important in degraded areas to ensure the nutrient return to the soil. The data obtained suggest that the cultivation of a mixed of 16 native trees contribute for produce the higher annual litterfall yields, besides produces leaf litterfall of better nutritional quality in relation to P, K, Ca, Mg and S. Therefore, mixed of native trees can be a promising option for reactivation of nutrient cycling and organic matter formation in mined area of bauxite in the Brazilian Atlantic Forest.

ABSTRACT Mining is a significant driver of soil mobilization, which impacts its physical, chemical, and biological properties. Changes in land-use affect the distribution of organic matter fractions in stable aggregates, a process that is still poorly understood, especially in drastically altered areas. Recovering and monitoring soil quality to ensure the sustainable development of agricultural crops in these areas after mining is challenging. This study aimed to evaluate the influence of agronomic practices in soil rehabilitation in a bauxite-mined area after three years of field experiment installations through an assessment of organic properties in soil and aggregate classes; an attempt was also made at proposing and elaborating a Soil Quality Index (SQI), which encompasses the soil’s physical, chemical, and organic properties. Different combinations of fertilization treatments and ground cover plants intercropping with coffee were evaluated as rehabilitation practices. The results showed that after three years of rehabilitation, when organic (OF), chemical (CF), and OF+CF fertilizers were applied to the areas of coffee intercropped with Brachiaria (B), they provided higher C and N contents to the soil and aggregates classes, as well as the compartments of soil organic matter (SOM). The minimum set of soil quality indicators for reclaimed bauxite-mined areas was composed of organic indicators: labile organic carbon (LOC) and mineral-associated organic matter (C-MOM); chemical indicators including pH and effective cation-exchange capacity (t), and physical indicators such as the bulk density (BD) and stable aggregates index in water (SAIW). The t and pH were the variables most sensitive to the management systems implanted during the rehabilitation of the mined area, and, therefore, were considered the best indicators of soil quality. Brachiaria was the cover plant that contributed most to improving the soil quality of mined bauxite areas by increasing the SQI, especially when fertilized. In general, when applied to the Brachiaria, the OF+CF fertilization presented a SQI of 0.78, differing statistically from that of the natural vegetation (1.00). Fertilizers and cover crops in association with coffee in the bauxite-mined areas improved the physical, chemical, and organic properties of the soil, thus representing a viable option for reconditioning mineral exploration areas.

Abstract Background Data on post-acute COVID-19 in autoimmune rheumatic diseases (ARD) are scarce, focusing on a single disease, with variable definitions of this condition and time of vaccination. The aim of this study was to evaluate the frequency and pattern of post-acute COVID-19 in vaccinated patients with ARD using established diagnosis criteria. Methods Retrospective evaluation of a prospective cohort of 108 ARD patients and 32 non-ARD controls, diagnosed with SARS-CoV-2 infection (RT-PCR/antigen test) after the third dose of the CoronaVac vaccine. Post-acute COVID-19 (≥ 4 weeks and > 12 weeks of SARS-CoV-2 symptoms) were registered according to the established international criteria. Results ARD patients and non-ARD controls, balanced for age and sex, had high and comparable frequencies of ≥ 4 weeks post-acute COVID-19 (58.3% vs. 53.1%, p = 0.6854) and > 12 weeks post-acute COVID-19 (39.8% vs. 46.9%, p = 0.5419). Regarding ≥ 4 weeks post-acute COVID-19, frequencies of ≥ 3 symptoms were similar in ARD and non-ARD controls (54% vs. 41.2%, p = 0.7886), and this was also similar in > 12 weeks post-acute COVID-19 (68.3% vs. 88.2%, p = 0.1322). Further analysis of the risk factors for ≥ 4 weeks post-acute COVID-19 in ARD patients revealed that age, sex, clinical severity of COVID-19, reinfection, and autoimmune diseases were not associated with this condition (p > 0.05). The clinical manifestations of post-acute COVID-19 were similar in both groups (p > 0.05), with fatigue and memory loss being the most frequent manifestations. Conclusion We provide novel data demonstrating that immune/inflammatory ARD disturbances after third dose vaccination do not seem to be a major determinant of post-acute COVID-19 since its pattern is very similar to that of the general population.

Abstract: Framework: Health tourism is currently one of the fastest growing forms of tourism. In Portugal, the “Tourism Strategy 2027” highlighted thermal activity as a means of economic development in the country's regions. On March 11, 2020, WHO declared a covid-19 pandemic. In Portugal, all thermal establishments took the initiative to suspend activity. After the lockdown period the units had to adapt to restart following the guidelines of the health authorities. Goals This study aims to emphasize the spa health tourism sector in Portugal in the context of the Covid-19 pandemic, analyze consumer behavior, and suggest future research on the topic. Paper organization: We present qualitative research, through content analysis using WebQDA software and a bibliometric analysis of co-occurrence of keywords in the thermal field, using the VOSviewer software. The analysis was conducted considering public statements from representatives of 21 units in mainland Portugal, published in the media, as of March 2020. Results: The analyses point to a high appreciated value by the customers to the item safety and to the aesthetic and medicinal treatments. There were no differences in behavior between public and private entities. All regions in mainland Portugal behaved the same way in terms of compliance with the health organization's guidelines, seeking to give the customer more safety and confidence. The training and actions of the human resources were essential to adapt the spas to guarantee strict safety and hygiene rules, as well as the respect for physical distance. In terms of marketing and innovation, the biggest references from the clients are at the product level. Final considerations: The current context of the Covid-19 pandemic favors the use of spas for their curative aspect related to lung problems, post-disease. There are several opportunities for hydrotherapy and research associated with the sector. It is important to draw new lines connected to its potential role in accelerating healing and prevention of coronavirus.

Abstract Lesbians face many barriers in health services, and experience prejudice, stigmatization and the invisibility of their health demands. This article aimed at understanding the meanings attributed by primary care nurses to health care practices directed at lesbians. This is a qualitative research carried out with 15 nurses who worked in primary care in Teresina, Piauí. The analysis was based on Pierre Bourdieu’s theoretical framework of habitus, field and symbolic violence. It was observed that the practices of nurses in the field of primary care follow heteronormative protocols. Therefore, it is essential that these nurses develop other habitus, aiming to guarantee different types of identities within the health services.

Resumo A necessidade de recorrer ao gestor público de saúde para efetivar o direito ao acesso a medicamentos caracteriza a via administrativa. O estudo analisou as percepções dos usuários que acionaram a via administrativa sobre as barreiras para o acesso a medicamentos no setor público de saúde de uma capital brasileira. Foi realizado estudo de método misto com grupo focal, questionário com demandantes e descrição dos medicamentos demandados pela via administrativa. Os resultados apontam a interdependência da assistência farmacêutica com as áreas de interfaceamento para a garantia do acesso. As barreiras relativas aos indivíduos refletem o comprometimento do desenvolvimento da cidadania, justificando o custo do medicamento motivar a demanda. As barreiras à prestação dos serviços contemplam disponibilidade irregular dos medicamentos, insuficiência de recursos e qualidade insatisfatória dos serviços. A dificuldade para conseguir consultas médicas e a exigência da prescrição originada no setor público são barreiras ao setor saúde. As barreiras acima do setor saúde são cumprimento dos procedimentos administrativos, corrupção e clientelismo. A via administrativa intensifica as iniquidades no acesso à saúde no Brasil.

Abstract The need to request public health managers to ensure the right of access to medicines characterizes an administrative case and the method to do so is called the administrative route. This mixed method study aimed to analyze the perceptions of plaintiffs requesting medications by the administrative route about barriers to access medicines in the Brazilian public health sector. Data were gathered through focus groups and questionnaires. The results point to the interdependence of pharmaceutical services with the interfacing areas to ensure access. The barriers related to individuals reflect the commitment to develop citizenship, justifying the cost of the medicine to motivate the demand. Barriers to service provision include irregular availability of medicines, insufficient resources, and unsatisfactory quality of services. The difficulty in obtaining medical consultations and prescriptions originating in the public sector are barriers to the health sector. The barriers above the health sector are compliance with administrative procedures, corruption, and clientelism. The administrative route intensifies inequities in access to healthcare in Brazil.

The use of computer simulation to predict the behavior of devices and materials allows for the acceleration of system operation and reduces costs, as it eliminates the need to build prototypes for testing. This work proposes the construction of 3 models with different complexities to simulate the electrical behavior of a solid electrolyte fuel cell. Experimental data were compared with simulation data. The experimental data were obtained from the production of a solid YSZ by tape casting, sintered at 1550 °C. The material was characterized using impedance spectroscopy in atmospheric air. From the experimental data, a computer simulation was conducted by using commercial code (COMSOL Multiphysics v.5.4). The construction of the model was developed to 1D, 2D axisymmetric and 3D dimensions to simulate an electrolyte to use in cylindrical planar SOFC. Nyquist Impedance graphics were plotted for the three geometries in comparison with the experimental value. No variation was observed between the curves obtained by the different geometries for the same interface. In other words, the interface complexity did not interfere in the result obtained for the same experimental data. We concluded that the 1D model is ideal to predict the influence of operational parameters because it is simpler and saves analysis time, maintaining the reliability and accuracy of the results.

ABSTRACT Soil tillage systems can influence crop development. In order to evaluate the effects of tillage equipment on soil physics and soybean development, five soil tillage systems were evaluated (mouldboard plow, disc plow, intermediate harrow, scarifier and rotary hoe) and their effect on aggregates of a dystrophic Red Yellow Latosol. A completely randomized design with four replications was used. The tillage systems influenced the average height of the plants in the soybean crop. Soil preparation with disc plows and moldboards cause larger plant sizes compared to the scarifier. Periodic soil tillage systems do not influence the development and productivity of the soybean crop.

RESUMO Sistemas de preparo do solo podem influenciar o desenvolvimento das culturas. Com o objetivo de avaliar os efeitos de equipamentos de preparo na física do solo e desenvolvimento da soja, foram avaliados cinco sistemas de preparo do solo (arado de aivecas, arado de discos, grade aradora intermediária, escarificador e enxada rotativa) e seu efeito nos agregados de um Latossolo Vermelho Amarelo distrófico. Foi utilizado o delineamento inteiramente casualizado com quatro repetições. Os sistemas de preparo do solo influenciaram na altura média das plantas na cultura da soja. O preparo do solo com os arados de discos e aivecas ocasionam maior tamanho de plantas em comparação ao escarificador. Os sistemas de preparo periódico do solo não influenciam no desenvolvimento e a produtividade da cultura da soja.

Myelodysplastic syndromes (MDS) are a heterogeneous group of hematological malignancies characterized by dysplasias, ineffective hematopoiesis and risk of acute myeloid leukemia transformation. Approximately 90% of MDS patients present mutations in genes involved in various cell signaling pathways. Specialized DNA polymerases, such as POLN, POLI, POLK, POLQ, POLH, POLL and REV3L, insert a nucleotide opposite replication–blocking DNA lesions in an error-prone manner and, in this way, sometimes can actively promote the generation of mutation. For the best of our knowledge, has not been described the mutations of these genes in MDS. DNA target sequencing CDS regions of the REV3L gene was performed in a 58-year-old man diagnosed as High Risk Myelodysplastic Syndrome. The patient presented very low hemoglobin, increased number of blasts, karyotype:47,XY,+8[6]/47,XY,del(7)(q32),+8[7], no response to hypomethylating therapy (decitabine), all markers of poor prognosis. Target sequencing identified a mutation c.9253-6T>C REV3L (Substitution - intronic) with VAF (variant allele frequency) = 16% considered pathogenic according to Functional Analysis through. Hidden Markov Models (FATHMM). This is the first evidence of REV3L mutation in MDS and, of utmost importance, associated with poor prognosis.

Abstract After natural fermentation and solar drying, sour cassava starch acquires expansion property. Traditionally, solar drying occurs without protection, and consequently physical contamination can arise. Thus, the aim of this study was to produce sour cassava starch using a low-cost solar dryer to prevent contamination, whilst retaining the expansion property. The samples were characterized in relation to chemical composition, microscopy and physical contaminants, as well as expansion, thermal, pasting, structural and technological properties. In addition, biscuits were prepared and compared with commercial samples. The solar dryer provided faster drying and lower moisture levels than the control. The specific volumes of the sun-dried products were similar to the control, with minimized contamination. The granules of the starches showed slight erosion on their surface, which was probably due to amylolytic enzymes. X-ray diffraction showed a typical A-type pattern. DSC analysis resulted in higher gelatinization temperatures and enthalpy changes for the sour cassava starch. The pasting properties showed a reduction in the viscosity peak at neutral pH. Although the cassava starch biscuits made with sour cassava starch dried in the solar dryer presented lower expansion levels in relation to the other biscuits produced with commercial sour cassava starch, they had desirable sensory characteristics.

Resumo O amido de mandioca fermentado (polvilho azedo) é valorizado como matéria-prima para o preparo de fast food. Sua produção tradicional por fermentação natural e exposição ao sol favorece a contaminação e impurezas, além de depender das condições climáticas. A literatura explica a expansão característica do polvilho azedo como uma reação do ácido lático produzido durante a fermentação e a radiação solar. Com o objetivo de avaliar um processo comercial em fluxo contínuo, uma lâmpada modular (UV-C) foi empregada para substituir a exposição à luz solar. As doses selecionadas foram 1.000, 5.000 e 10.000 Joules por litro (J l-1). A suspensão de amido de mandioca nativo em água a 6% (base seca) foi ajustada para 4% de ácido lático (base seca) e exposta à radiação UV-C: (a) sem ácido lático, (b) com reação de ácido lático por 1 hora, (c) com radiação ultravioleta, além da combinação de (ac) e (bc). Os resultados mostraram que apenas a combinação de acidificação e radiação ultravioleta (bc) permite uma expansão (11 cm3 g-1) superior ao polvilho azedo comercial (8,24 cm3 g-1) adotado como padrão. Concluiu-se que é possível obter um sucedâneo para o amido fermentado pela acidificação do amido de mandioca nativo com ácido lático em um sistema de fluxo contínuo a partir de uma dose em torno de 5.000 J l-1 de radiação UV-C.

Abstract The Brazilian fermented cassava starch (polvilho azedo) is prized as a raw material for fast food preparation. Its traditional production by natural fermentation and exposure to sunlight favors contamination and impurities, in addition to depending on the climate. The literature explains the characteristic expansion of polvilho azedo as a reaction of the lactic acid produced during fermentation and sun radiation. With the aim to evaluate a commercial continuous flow process, a modular lamp (UV-C) was evaluated to substitute exposure to sunlight. The selected doses were 1,000, 5,000 and 10,000 Joules per liter (J l-1). Native cassava starch suspension in water at 6% (dry basis) was adjusted to 4% lactic acid (dry basis) and exposed to UV-C radiation: (a) without lactic acid, (b) with lactic acid reaction for 1 hour, (c) with ultraviolet radiation, in addition to the combination of (ac) and (bc). The results showed that only the combination of acidification and ultraviolet radiation (bc) allows an expansion (11 cm3 g-1) higher than the commercial polvilho azedo (8.24 cm3 g-1) adopted as standard. It was concluded that is possible to achieve a substitute for fermented cassava starch by acidification of native cassava starch with lactic acid in a continuous flow system starting with a dose around 5,000 J l-1 of UV-C radiation.

ABSTRACT: Accidents related to the rupture of iron ore tailings dams have dramatically impacted on the Brazilian natural ecosystem. So, the development of strategies to recover soil organic matter levels and build-up Technosols are required. This study aimed to evaluate the effect of N-mineral and -organic fertilization and the rhizospheric effect on soil organic matter mineralization from Technosols built under iron ore tailings. The experiment was carried out in a greenhouse; we used a factorial scheme 2 × 2 × 3: without and with the plant Crotalaria juncea ; without and with mineral fertilization; and three different organic fertilization (without organic fertilization, sewage sludge, and household waste composting), with four randomized blocks. The experimental units were PVC columns installed with a top layer of iron ore tailing from a dam, where gases were sampled to determine the CO2-C, CH4-C concentrations, and CO2-δ13C. The organic fertilization promoted a positive priming effect of 184 %. However, with mineral fertilization, no effect was observed in soil derived-CO2-C accumulated and priming effect. Similarly to non-planted soil, the planted soils with mineral and organic fertilization promoted a steady reduction in soil derived-CO2-C accumulated and rhizosphere priming effect. The soil with mineral fertilization improved in 5.52 and 0.45 g per column the shoot and root dry matter of Crotalaria when compared to the soil without mineral fertilization. In summary, the organic fertilization in Technosols built over iron ore tailings dams during revegetation was not enough to ensure the plant development and preservation of soil organic matter. However, the combination of mineral and organic fertilization promoted negative rhizosphere priming effect and a significant increase in plant biomass.

RESUMO As embalagens têm como função básica proteger o alimento e garantir a sua integridade comercial. Podem ser produzidas a partir de materiais biodegradáveis com funcionalidades específicas, tais como ação antimicrobiana e antioxidante. Além disso, pesquisas vêm sendo desenvolvidas de modo a substituir os aditivos sintéticos por outros naturais, como os extratos vegetais, devido aos compostos químicos presentes em suas misturas. O poli(butileno adipato co-tereftalato) - (PBAT) vem sendo extensivamente estudado como uma possível substituição aos polímeros convencionais devido à sua biodegradabilidade. Desse modo, o objetivo desse trabalho foi avaliar as potencialidades dos extratos vegetais de jurema preta (Mimosa tenuiflora) e cajueiro (Anacardium occidentale Linn), a fim de aplicá-los como aditivos em embalagens de PBAT com propriedades ativas antioxidantes e antimicrobianas. Os extratos foram obtidos pela técnica de extração Sohxlet em três diferentes tempos, 4, 6 e 8 horas, cujo melhor rendimento ocorreu nos tempos de 6 horas para jurema preta e 4 horas para cajueiro. No teste de presença de flavonóides o extrato de jurema preta apresentou maior concentração e no teste de fenólicos totais, utilizando o método de Folin-Ciocalteau, o cajueiro obteve maior concentração. Ambos os extratos apresentaram capacidades antioxidantes significativas pelos dois métodos, fosfomolibdênio e DPPH. cajueiro apresentou melhor halo de inibição frente ao Staphylococcus aureus, e, por isso, foi determinada a sua concentração mínima inibitória (CMI), 0,0170 g.mL-1. Esse extrato foi incorporado ao PBAT, para o ensaio de migração no meio etanólico, por meio do qual foi determinado um modelo cinético e foi observado que a taxa de migração, 0,0167 ?g.mL-1.min-1, foi reduzida em cerca de um dia, indicando bom potencial do extrato para esses tipos de embalagem.

ABSTRACT Packaging has the basic function of protecting the food and ensuring its commercial integrity. They can be produced from biodegradable materials with specific functionalities such as antimicrobial and antioxidant action. In addition, research has been carried out to replace synthetic additives with natural additives, such as plant extracts, due to the chemical compounds present in their mixtures. Poly (butylene adipate co-terephthalate) - (PBAT) has been extensively studied as a possible replacement for conventional polymers due to its biodegradability. Thus, the objective of this work was to evaluate the potentialities of jurema preta (Mimosa tenuiflora) and cajueiro (Anacardium occidentale Linn) plant extracts in order to apply them as additives in PBAT packages with antioxidant and antimicrobial active properties. The extracts were obtained by the Sohxlet extraction technique at three different times, 4, 6 and 8 hours, with the best yield at 6 hours for jurema preta and 4 hours for cajueiro. In the flavonoid presence test the jurema preta extract presented higher concentration and in the total phenolics test, using the Folin-Ciocalteau method, the cashew tree obtained the highest concentration. Both extracts showed significant antioxidant capacities by the two methods, phosphomolybdenum and DPPH. Cashew tree presented better inhibition halo against Staphylococcus aureus, and therefore its minimum inhibitory concentration (MIC) was determined, 0.0170 g.mL-1. This extract was incorporated into the PBAT for the ethanolic migration test, by means of which a kinetic model was determined and it was observed that the migration rate, 0.0167 ?g.mL-1.min-1, was reduced by about a day, indicating good extract potential for these types of packaging.
