Abstract Introduction: Autoimmune hepatitis (AIH) has a spectrum of symptoms ranging from asymptomatic disease to acute severe hepatitis, chronic hepatitis, and decompensated cirrhosis. The acute presentation is not rare and could represent genuine acute AIH (GAAIH) or acute exacerbation of chronic autoimmune hepatitis. We aimed to identify the prevalence, clinical features, and prognostic factors associated with GAAIH and compare these cases with acute exacerbation of chronic AIH. Methods: This cross-sectional observational study evaluated patients with acute AIH presentation, defined as total bilirubin >5 times the upper limit of normality (xULN) and/or alanine aminotransferase >10 xULN, and no prior history of liver disease. Histology findings of acute disease defined GAAIH. Bivariate analyses were performed to identify factors associated with the GAAIH, when compared with acute exacerbation of chronic AIH. Results: Seventy-two patients with acute presentation of AIH were included and six (8.3%) of them presented GAAIH. Comparative analysis between patients with GAAIH and patients with acute exacerbation of chronic AIH revealed that prothrombin activity (96% [74-100] vs. 61% [10-100]; p = 0.003) and albumin levels (3.9 ± 0.2 g/dL vs. 3.4 ± 0.5 g/dL; p < 0.001) were higher in patients with GAAIH. The International Autoimmune Hepatitis Group score was higher in patients with acute exacerbation of chronic AIH (18.5 [8-23] vs. 16.5 [15-17]; p = 0.010). Compared to 15.2% of acute exacerbation of chronic AIH, complete therapeutic response to treatment was achieved in 67.7% of cases with GAAIH (p = 0.018). Conclusions: GAAIH was rare (8.3%), and patients with this presentation exhibited more preserved liver function tests, suggesting that most cases presenting with loss of function are acute exacerbation of chronic AIH. Additionally, patients with GAAIH had a better complete therapeutic response, suggesting a more preserved liver function at presentation, and early diagnosis has a positive therapeutic implication.

Resumo Introdução: A hepatite autoimune (HAI) apresenta um espectro de sintomas que varia de doença assintomática a hepatite aguda grave, hepatite crónica e cirrose descompensada. A apresentação aguda não é rara e pode representar hepatite autoimune aguda genuína (HAIAG) ou exacerbação aguda de hepatite autoimune crónica (EAHAIC). O nosso objetivo foi identificar a prevalência, caraterísticas clínicas e fatores prognósticos associados à HAIAG, e comparar esses casos com EAHAIC. Métodos: Estudo observacional, transversal, incluindo doentes com apresentação aguda de HAI, definida como bilirrubina total > 5 vezes o limite superior da normalidade (xLSN) e/ou ALT > 10 xLSN, e sem história prévia de doença hepática. HAIAG foi definida pela presença de achados histológicos de doença aguda. Análises bivariadas foram realizadas para identificar fatores associados à HAIAG, quando comparado com o EAHAIC. Resultados: Foram incluídos setenta e dois doentes com apresentação agu-da de HAI, dos quais seis (8.3%) com HAIAG. A análise comparativa entre doentes com HAIAG e doentes com EAHAIC mostrou que a atividade de protrombina (96%(74-100) versus 61% (10-100; p=0.003) e os níveis de albumina (3,9 ± 0,2 g/dL vs. 3,4 ± 0,5 g/dL; p < 0,001) foram significativamente mais elevados em pacientes com HAIAG. O score do Grupo Internacional de Hepatite Autoimune foi mais elevado em doentes com EAHAIC (18.5 (8-23) versus 16.5 (15-17); p=0.010). A resposta terapêutica completa ao tratamento foi alcançada em 66.7% dos casos de HAIAG (vs. 15,2% na EAHAIC, p=0,018). Conclusões: A HAIAG é rara (8.3%), e os doentes com esta apresentação mostraram testes de função hepática mais preservados, sugerindo que a maioria dos casos com perda de função são EAHAIC. Além disso, os doentes com HAIAG tiveram maior taxa de resposta terapêutica completa, sugerindo que uma função hepática mais preservada na apresentação e o diagnóstico precoce tem uma implicação terapêutica positiva.

Abstract: This article has the general aim to understand the production of masculinities for men who call themselves “macho” on erotic dating apps. We start from a theoretical framework that question the power regime that structures the understanding of masculinities and sexuality, using the regulatory matrix of heteronormativity as a basis. As for the method, we use qualitative social research on the internet from an application designed for erotic encounters between men to locate and build knowledge in the pandemic context and at a peripheral/university region of the city of Recife/PE. For analysis, we used maps of association of ideas, considering the dialogue and the crossings of meaning production. Our results and discussions led us to think about the imperative of normative masculine performance regarding the body and the relational level, as well as personal conflicts in the face of social assumptions about masculinities in practices of cruising.

ABSTRACT Background: The macauba (Acrocomia aculeata (Jacq.) Lodd. ex Mart.) is a palm tree native to tropical regions and occurs in much of the Brazilian territory. Current studies are focused on the extraction and exploitation of vegetable oil from this fruit. However, there are few studies on the residue, the endocarp, which represents approximately 25% of the total mass of the fruit. Studies that search for solutions for using residue, thus adding value, and generating environmentally friendly products, are of fundamental importance. Thus, this research aimed to evaluate the physical and mechanical properties of reconstituted wood panels produced with different proportions of macauba endocarp particles to replace pine wood particles, in addition to characterize the physical and chemical properties of macauba endocarp. The chemical characterization tests were performed according to applicable standards. The basic density was determined according to the NBR 11941 standard. Thermogravimetric analysis (TGA), X-ray diffractometry (XRD) and Fourier transform infrared spectroscopy (FTIR) were also performed. The particleboards panels were produced with a nominal density of 0.70g/cm³ and dimensions of 25x25x1.5cm. Five different treatments were evaluated with variations in the proportion of macauba endocarp particles in the core of the panel. For particle agglutination, phenol-formaldehyde adhesive was used at a proportion of 9% for the core and 12% for the faces, based on the dry mass of each panel. Scanning electron microscopy (SEM) was used to analyze the panel surfaces. Results: The endocarp of Acrocomia aculeata has low extractive content, high lignin content and high densification, 1.23g/cm³, when compared to Pinus oocarpa wood, 0.43g/cm³. All panels were classified as low density according to CS 236-66 and had an average apparent density between treatments of 0.586g/cm³. A greater dimensional stability and a decrease in the static bending properties of the panels was observed as the proportion of macauba endocarp particles increased. The internal bonding of the panels showed a positive result with the increase in the use of particles of the residue. Conclusion: The panels produced have potential for use for non-structural purposes. Background Jacq. Jacq (Jacq. Lodd Mart.

Abstract Background: Spinal ventral root injuries generate significant motoneuron degeneration, which hinders full functional recovery. The poor prognosis of functional recovery can be attributed to the use or combination of different therapeutic approaches. Several molecules have been screened as potential treatments in combination with surgical reimplantation of the avulsed roots, the gold standard approach for such injuries. Among the studied molecules, human natural killer-1 (HNK-1) stands out as it is related to the stimulation of motor axon outgrowth. Therefore, we aimed to comparatively investigate the effects of local administration of an HNK-1 mimetic peptide (mp-HNK-1) and systemic treatment with ursolic acid (UA), another HNK-1 mimetic, after ventral root avulsion and reimplantation with heterologous fibrin biopolymer (HFB). Methods: Female mice of the isogenic strain C57BL/6JUnib were divided into five experimental groups: Avulsion, Reimplantation, mp-HNK-1 (in situ), and UA (systemic treatment). Mice were evaluated 2 and 12 weeks after surgery. Functional assessment was performed every four days using the Catwalk platform. Neuronal survival was analyzed by cytochemistry, and glial reactions and synaptic coverage were evaluated by immunofluorescence. Results: Treatment with UA elicited long-term neuroprotection, accompanied by a decrease in microglial reactions, and reactive astrogliosis. The neuroprotective effects of UA were preceded by increased glutamatergic and GABAergic inputs in the ventral spinal cord two weeks after injury. However, a single application of mp-HNK-1 had no significant effects. Functional analysis showed that UA treatment led to an improvement in motor and sensory recovery. Conclusion: Overall, the results indicate that UA is neuroprotective, acting on glial cells and synaptic maintenance, and the combination of these findings led to a better functional recovery.

ABSTRACT Asbestos was largely used in Brazil. It is a mineral that induces pleural and pulmonary fibrosis, and it is a potent carcinogen. Our objective was to develop recommendations for the performance of adequate imaging tests for screening asbestos-related diseases. We searched peer-reviewed publications, national and international technical documents, and specialists’ opinions on the theme. Based on that, the major recommendations are: Individuals exposed to asbestos at the workplace for ≥ 1 year or those with a history of environmental exposure for at least 5 years, all of those with a latency period > 20 years from the date of initial exposure, should initially undego HRCT of the chest for investigation. Individuals with pleural disease and/or asbestosis should be considered for regular lung cancer monitoring. Risk calculators should be adopted for lung cancer screening, with a risk estimate of 1.5%.

ABSTRACT The growing demand for gypsum in civil construction has stimulated studies to improve flexural strength and reduce its layer with water. Therefore, the objective was to evaluate the influence of incorporating multi-walled carbon nanotubes (MWCNT) into the gypsum matrix on its physical and mechanical properties. In the production of composites, the gypsum mass was obtained by different levels of functionalized MWCNT: 0%, 0.001%, 0.002%, 0.003% and 0.004%. Apparent density, observation of water and flexural strength and analysis of the nanocomposites were verified. Replacing gypsum with MWCNT can cause water absorption by 8.33% compared to the control. The apparent density of the compounds showed an increase, with the concentration of 0.004 MWCNT showing an increase of 3.21% when compared to the reference. Compounds with contents of 0.001 and 0.003% of MWCNT showed an improvement in flexural strength values, presenting of 6 MPa. There were improvements for the insertion of 0.001 MWCNT (9 MPa) compared to the control (7 MPa). Thus, the results indicate that replacing gypsum with MWCNT is a viable alternative to improving the mechanical and physical properties of gypsum, which can increasingly expand its use in civil construction.

ABSTRACT Background: Cases of coronavirus disease 2019 (COVID-19) requiring hospitalization continue to appear in vulnerable populations, highlighting the importance of novel treatments. The hyperinflammatory response underlies the severity of the disease, and targeting this pathway may be useful. Herein, we tested whether immunomodulation focusing on interleukin (IL)-6, IL-17, and IL-2, could improve the clinical outcomes of patients admitted with COVID-19. Methods: This multicenter, open-label, prospective, randomized controlled trial was conducted in Brazil. Sixty hospitalized patients with moderate-to-critical COVID-19 received in addition to standard of care (SOC): IL-17 inhibitor (ixekizumab 80 mg SC/week) 1 dose every 4 weeks; low-dose IL-2 (1.5 million IU per day) for 7 days or until discharge; or indirect IL-6 inhibitor (colchicine) orally (0.5 mg) every 8 hours for 3 days, followed by 4 weeks at 0.5 mg 2x/day; or SOC alone. The primary outcome was accessed in the “per protocol” population as the proportion of patients with clinical improvement, defined as a decrease greater or equal to two points on the World Health Organization’s (WHO) seven-category ordinal scale by day 28. Results: All treatments were safe, and the efficacy outcomes did not differ significantly from those of SOC. Interestingly, in the colchicine group, all participants had an improvement of greater or equal to two points on the WHO seven-category ordinal scale and no deaths or patient deterioration were observed. Conclusions: Ixekizumab, colchicine, and IL-2 were demonstrated to be safe but ineffective for COVID-19 treatment. These results must be interpreted cautiously because of the limited sample size.

ABSTRACT Amazonian soils have been suffering severe changes resulting from human activities in the region, causing significant changes in soil attributes that can contribute to greater susceptibility to erosion processes. Therefore, the present work aimed to estimate the erodibility in natural and anthropic environments in the southern region of the Amazon. Eight areas in the region were selected, including areas of native forest, savannah, cerradão, pasture and reforestation, delimiting 32 sampling points per area, with collections at a depth of 0.00-0.20 m, totaling 256 samples. Next, texture analysis and quantification of soil organic carbon were performed, and then erodibility was estimated by indirect prediction methods, Tukey’s test, Pearson’s correlation and factorial analysis of principal components. According to the results obtained, it was observed that the evaluated areas of native forest 1 and 2, cerradão and pasture present high susceptibility to erosion in relation to the cerrado, reforestation with genipap, teak and mixed areas. Therefore, it was noted that the high level of erodibility is associated with a greater predominance of sand fraction, K factor, Ki Kr and low clay content, as well as with the management employed in the areas. processes Therefore Amazon selected savannah 3 area 0.000.20 000020 0.00 0.20 0 00 20 0.00-0.2 m 25 samples Next performed methods Tukeys Tukey s test Pearsons Pearson components obtained 2 cerrado genipap fraction factor content 000 0.000.2 00002 0.0 020 0.2 0.00-0. 0.000. 0000 0. 02 0.00-0 0.000 0.00-

ABSTRACT Despite the increasing use of plaster as a construction material, due to its numerous advantages when compared to cement, its use is still restricted, because of its low mechanical resistance and high solubility in water. In this context, research has been carried out related to the addition of nanomaterials to improve the mechanical and physical properties of plaster in civil construction. A highly available, low-cost nanomaterial with excellent properties is nanotalc. In this work, nanocomposites with dimensions of 40 × 40 × 160 mm were produced with ultrafine micronized nanotalc replacing plaster in proportions of 0%; 0.5%; 1%; 1.5% and 2%. The physical and mechanical properties of the nanocomposites were evaluated according to standards. The nanocomposites produced with 1% nanotalc showed satisfactory results for physical and mechanical properties, with an increase of 1.8% in apparent density and 24.12% in compressive strength, and a decrease in water absorption of 6.23%, compared to the composite without the incorporation of nanotalc. The production of nanocomposites with the incorporation of 1% nanotalc is viable and shown to be promising, presenting potential for application as linings and internal partitions, since they showed low water absorption due to the hydrophobicity of nanotalc. material cement restricted context available lowcost cost work 4 16 0% 0 0.5% 05 5 1 15 1.5 2 2% standards 18 8 1.8 2412 24 12 24.12 strength 623 6 23 6.23% promising partitions 0.5 1. 241 24.1 62 6.23 0. 24. 6.2 6.

RESUMO No consórcio entre hortaliças pouco se conhece sobre as respostas fisiológicas. Conhecer o comportamento fisiológico é fundamental para avaliar a eficiência dessas espécies. Sendo assim, objetivou-se avaliar as respostas fisiológicas da rúcula consorciada com nirá sob diferentes arranjos espaciais e épocas de cultivo. O experimento foi conduzido no delineamento em blocos casualizados, em esquema de parcela subdividida, com os arranjos de cultivo {T1 = monocultivo de rúcula; T2 = duas linhas de rúcula com três de nirá (2R:3N); T3 = duas linhas de rúcula e duas de nirá (2R:2N); T4 = duas linhas de rúcula e uma de nirá (2R:1N)}, nas parcelas e as épocas de cultivo nas subparcelas (24 de julho e 03 de setembro). Avaliou-se a taxa de fotossíntese líquida, condutância estomática, transpiração, concentração interna de CO2, eficiência do uso da água, área foliar e produtividade. A maior taxa de fotossíntese líquida foi observada no arranjo 2R:3N para a primeira época de cultivo. A transpiração, condutância estomática e concentração de carbono interna foram menores na segunda época de cultivo. As eficiências intrínseca e instantânea do uso da água foram maiores na segunda época de cultivo. A rúcula em monocultivo e o cultivo consorciado 2R:1N alcançaram produtividade semelhante. As respostas fisiológicas da rúcula não foram influenciadas pelos arranjos de cultivo com nirá, indicando que a cultura pode ser arranjada sem prejuízo à eficiência do processo fotossintético. O consórcio 2R:1N possibilitaram o melhor desempenho produtivo na primeira época de cultivo.

ABSTRACT In intercropping between vegetable species, little is known about physiological responses. Thus, getting to know the physiological behavior of these crops is essential to define whether the species are efficient. The aim of this study was to evaluate the physiological responses of arugula/nirá intercropping under different arrangements and growing seasons. The experiment was conducted in a randomized block design, in a split-plot scheme, using the following cultivation arrangements: T1 = arugula monocropping; T2 = two rows of arugula with three rows of nirá (2R:3N); T3 = two rows of arugula with two rows of nirá (2R:2N); T4 = two rows of arugula with one row of nirá (2R:1N), in plots and growing seasons in the subplots (July 24th and September 3rd). We evaluated net photosynthesis rate, stomatal conductance, transpiration, internal carbon concentration, water use efficiency, leaf area and productivity. The highest rates of net photosynthesis were obtained in 2R:3N arrangement in the first growing season. Transpiration, stomatal conductance and internal carbon concentration were lower in the second growing season. The intrinsic and instantaneous water-use efficiencies were higher in the second growing season. Arugula monocropping and the 2R:1N arrangement reached similar productivity. The physiological responses of arugula were not influenced by the nirá cultivation arrangements, indicating that the crop can be arranged without harming the efficiency of the photosynthetic process. The 2R:1N intercropping allowed the best productive performance in the first growing season.
