Abstract Every activity that involves exploitation of natural resources, such as fishing, needs to be organized and conducted based on information from monitoring programs to allow continuous evaluation. With the increasing fishing pressure in Brazil, the understanding of the importance of fisheries monitoring programs and how they can inform and assist in conservation decision-making remains limited. Based on the literature on fisheries and participatory conservation, we call attention to the need to generate information on the national fisheries sector in order to improve fisheries in the country. Given the context of the need to generate information on fishing stocks under exploitation, as well as to identify potential alternative fisheries and carry out various sectoral analyses in compliance with the 2030 Agenda for Sustainable Development, we present and discuss in the present paper the lack of a system of continuous fishing monitoring in Brazil and its effects on the fisheries sustainability in the country.

Resumo Toda atividade que atua envolvendo a exploração de recursos naturais, como a pesca, precisa ser organizada e conduzida com base nas informações dos programas de monitoramento para permitir uma avaliação contínua. Com o aumento da pressão pesqueira no Brasil, o entendimento da importância dos programas de monitoramento da pesca e como eles podem informar e auxiliar na tomada de decisões de conservação permanece limitado. Com base na literatura sobre pesca e conservação participativa, chamamos a atenção para a necessidade de gerar informações sobre o setor pesqueiro nacional para melhorar a pesca no país. Dado o contexto da necessidade de gerar informações sobre os estoques pesqueiros em exploração, bem como identificar potenciais alternativas de pesca e realizar diversas análises setoriais em conformidade com a Agenda 2030 para o Desenvolvimento Sustentável, é apresentada e discutida no presente trabalho a falta de um sistema de monitoramento contínuo da pesca no Brasil e seus efeitos na sustentabilidade da pesca no país.

ABSTRACT Objectives: Evaluate bone healing time, consolidation, and the complication rate between the minimally invasive plate osteosynthesis and open reduction with plate osteosynthesis in humeral diaphyseal fractures with an intact wedge (AO 12B2). Methods: A retrospective study was carried out between 2016 and 2020. The medical records and radiographs of 18 patients were analyzed, and data were collected regarding the time of consolidation, age, sex, plate size, number of screws, complications such as iatrogenic injury damage to the radial nerve, material failure, and postoperative infection. Results: No statistically significant differences were observed in the variables of age, sex, plate size, and number of screws used or in the RUSHU index (Radiographic Union Score for Humeral fractures). There were no postoperative infections, material failure, or need for reoperation, nor cases of secondary radial nerve injury. After one year, all patients had a consolidation index analyzed by RUSHU >11. Conclusion: both techniques showed similar results, with a high consolidation rate and low rates of complications or iatrogenic damage to the radial nerve. Evidence level III; Retrospective comparative study .

In order to contribute to knowledge of the epidemiology of American cutaneous leishmaniasis (ACL) among indigenous people living in sylvatic regions, we studied the sand fly fauna collected in areas of disease transmission in the Brazilian Amazon. Our two datasets reported here are comprised of occurrence data for sand flies from the Suruwaha Indigenous Land in the state of Amazonas collected between 2012-1013, and the Wajãpi Indigenous Land in the state of Amapá collected between 2013-2014. Sand flies were collected using unbaited CDC-like light traps at various sites within each study area and were identified to species-level by taxonomists with expertise in Amazonian fauna. A total of 4,646 records are reported: 1,428 from the Suruwaha and 3,218 from the Wajãpi. These records will contribute to a better understanding of ACL transmission dynamics, as well as the distribution of insect vectors, in these areas.

Resumo Objetivo Comparar a taxa de maturação oocitária no tratamento de fertilização in vitro (FIV) emrelação so o uso de gonadotrofina coriônica humana (hCG), agonista de hormônio liberador de gonadotrofina (GnRH), e gatilho duplo e avaliar os fatores de risco associados a taxas de maturação subótimas. Métodos Estudo de coorte retrospectivo com 856 mulheres submetidas à FIV. Elas foram classificadas em 3 grupos (1 - hCG, 2 - GnRH agonista, 3 - gatilho duplo). O desfecho primário foi a taxa de maturação por gatilho, e os desfechos secundários foram a taxa de gravidez por recuperação de oócitos e as correlações entre a baixa taxa de maturação bem como as características clínicas e do tratamento das mulheres. Resultados A taxa de maturação foi de 77% no grupo 1; 76% no grupo 2, e 83% no grupo 3 (p=0,003). O grupo 2 apresentou mulheres com melhor reserva ovariana, maior número de oócitos coletados, oócitosmaduros, e embriões, emcomparação aos demais grupos (p<0,001). A taxa cumulativa de gravidez clínica não foi diferente entre os grupos (p=0,755). Baixa reserva ovariana e baixas doses de hormônio folículoestimulante (FSH) administradas durante o estímulo foram associadas a uma maior chance de taxa de maturação nula. Conclusão As taxas de maturação oocitárias e os resultados de FIV foram semelhantes em todos os grupos. A baixa reserva ovariana está associada aos piores resultados do tratamento.

Abstract Objective To compare the oocyte maturation rate in the treatment of in vitro fertilization (IVF) in terms of the use of human chorionic gonadotropin (hCG), agonist gonadotropin-releasing hormone (GnRH) and dual trigger and to evaluate the associated risk factors for sub-optimal maturation rates. Methods A retrospective cohort study with 856 women who underwent IVF. They performed oocyte retrieval and were classified into 3 groups (1 - hCG, 2 - GnRHagonist, 3 - dual trigger). The primary outcome was maturation rate per trigger, and the secondary outcomes were the pregnancy rate per oocyte retrieval and the correlations between low maturation rate as well as the clinical and treatment characteristics of women. Results The maturation rate was 77% in group 1; 76% in group 2, and 83% in group 3 (p=0.003). Group 2 showed women with better ovarian reserve, greater number of oocytes collected, and more mature oocytes and embryos compared with the other groups (p<0.001). The cumulative clinical pregnancy rate was no different between the groups (p=0.755). Low ovarian reserve and low doses of follicle-stimulating hormone (FSH) administered during the stimulus were associated with a higher chance of null maturation rate. Conclusion The oocyte maturation rates and IVF results were similar in all groups. Low ovarian reserve is associated with the worst treatment results.

Abstract Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the etiological agent of the disease coronavirus 2019 (COVID-19) in humans. SARS-CoV-2 has been identified in cats with or without clinical signs. Case presentation: We describe the pathological and molecular findings in a six-month-old asymptomatic cat with SARS-CoV-2 infection from Brazil, belonging to a human family with COVID-19 cases. The pool of nasopharynx and oropharynx swabs at day zero tested positive by RT-qPCR for SARS-CoV-2. No amplification resulted from molecular testing performed on days 7 and 14. The cat was hit by a car and died 43 days after the molecular diagnosis. Immunohistochemistry at post-mortem examination demonstrated nucleocapsid protein in samples from the lungs, kidneys, nasal conchae, trachea, intestine, brain and spleen. Conclusion: The present study has highlighted the possibility that viral antigens can be detected by immunohistochemistry in multiple organs six weeks after infection, although the same tissues tested negative by RT-PCR.

Resumo O objetivo deste trabalho foi avaliar a influência de diferentes coberturas de solo, tipos de fertilizantes e condicionadores de solo sobre a incidência e a severidade da cercosporiose (Cercospora coffeicola) em cafeeiro (Coffea arabica), em estádio vegetativo. O experimento foi realizado em delineamento de blocos ao acaso, em arranjo fatorial 3×2×5 (coberturas de solo × tipos de fertilizantes × condicionadores de solo) em parcelas subsubdivididas, com três repetições. Foram feitas comparações entre: três coberturas de solo (filme plástico, Urochloa decumbens e sem cobertura) nas parcelas; dois tipos de fertilizante (convencional e liberação controlada) nas subparcelas; e quatro condicionadores de solo (casca de café, gesso agrícola, polímero hidrorretentor e composto orgânico), bem como o controle, nas subsubparcelas. A área abaixo da curva de progresso da incidência e da severidade da doença mostrou as menores médias sem cobertura do solo, enquanto a do número de folhas foi maior com o uso do fertilizante de liberação controlada. O filme plástico proporcionou maior umidade do solo e menor resistência à penetração do solo. A composição química do composto orgânico reduziu o crescimento do cafeeiro. A cobertura do solo com filme plástico ou com U. decumbens favorece a alta incidência da cercosporiose; no entanto, proporciona maior umidade do solo e, consequentemente, melhora o crescimento do cafeeiro na fase vegetativa.

Abstract The objective of this work was to evaluate the influence of different soil coverings, fertilizer types, and soil conditioners on the incidence and severity of brown eye spot (Cercospora coffeicola) in coffee (Coffea arabica) during the vegetative stage. The experiment was carried out in a randomized complete block design, in a 3×2×5 factorial arrangement (soil coverings × fertilizer types × soil conditioners) in subdivided plots, with three replicates. Comparisons were made among: three soil covering (plastic film, Urochloa decumbens, and no covering) in the plots; two fertililizer types (conventional and controlled release) in the sub-plots; and four soil conditioners (coffee husk, agricultural gypsum, water retention polymer, and organic compound), as well as the control, in the sub-sub-plots. The area under the progress curve for disease incidence and severity showed the lowest mean without soil covering, whereas that for number of leaves was greater with the use of the controlled-release fertilizer. The plastic film provided a greater soil moisture and a lower soil resistance penetration. The chemical composition of the organic compound reduced coffee plants growth. Soil covering with plastic film or U. decumbens favors the high incidence of brown eye spot; however, it provides a greater soil moisture and, therefore, improves the growth of coffee plants in the vegetative stage.

Abstract Polyamide (PA) is a well-known and researched thermoplastic due to its excellent mechanical and physical properties, making it developed in the automotive sector, suitable for lighter vehicles, and, consequently, lower fuel consumption. This review manuscript presents the applications of PA-based materials in the manufacture of vehicle parts, with a description of their processing, a discussion about their thermal properties and the crystallization of polymer structure, the challenges of machining PA-based composite materials, and the feasibility of recyclability. This work aims to revise literature about the use of polyamide 6 (PA6), polyamide 66 (PA66), and polyamide 12 (PA12) and their composites reinforced with fiberglass (FG) and carbon fiber (CF) focused on the potential that these materials have as alternative materials for the automotive industry.

ABSTRACT Phosphate solubilizing microorganisms (PSM) and arbuscular mycorrhizal fungi (AMF) represent alternative strategies to reduce the cost and increase the production of cagaita (Eugenia dysenterica) seedlings associated with different substrates. This study aimed to assess the effect of inoculating PSM and AMF in different substrates for cagaita (Eugenia dysenterica) culturing. The experiment was installed with a completely randomized design, using a 4 × 2 factorial scheme, with four inoculation treatments (PSM, AMF, PSM + AMF, and Control - absence of inoculation), and two soils substrates (pure sandy substrate and mixed substrate). The substrates and microorganism had influence in cagaita seedling growth. The pure substrate conferred better performance of plant growth parameters. In this substrate, cagaita seedlings had higher stem diameter, shoot fresh and dry weight, root volume and root dry weight. The cultivation of seedlings in pure substrate inoculated with AMF and PSM provided greater Mo content in the leaves. The higher root volume of cagaita seedlings was obtained with the inoculation of PSM. A sandy substrate seems to be the most adequate for the cultivation of cagaita seedlings. In addition, co-inoculation provides higher Fe, Mg, and K content in the leaves, as this work showed.

RESUMEN Los microorganismos solubilizadores de fosfato (PSM) y los hongos micorrízicos arbusculares (HMA) representan estrategias alternativas para reducir el costo y aumentar la producción de plántulas de cagaita (Eugenia dysenterica) asociadas a diferentes sustratos. Este estudio tuvo como objetivo evaluar el efecto de la inoculación de PSM y HMA en diferentes sustratos para el cultivo de cagaita (Eugenia dysenterica). El experimento se instaló con un diseño completamente al azar, utilizando un esquema factorial 4 × 2, con cuatro tratamientos de inoculación (PSM, HMA, PSM + HMA y Control - ausencia de inoculación), y dos sustratos de suelo (sustrato arenoso puro y sustrato mixto). Los sustratos y microorganismos influyeron en el crecimiento de las plántulas de cagaita. El sustrato puro propició un mejor desempeño de los parámetros de crecimiento de las plantas. En este sustrato, las plántulas de cagaita presentaron mayor diámetro de tallo, masa fresca y seca de brotes, volumen de raíz y masa seca de la raíz. El cultivo de plántulas en sustrato puro inoculadas con HMA y PSM proporcionó mayor contenido de Mo en las hojas. El mayor volumen de raíces de plántulas de cagaita se obtuvo con la inoculación de PSM. Un sustrato arenoso parece ser el más adecuado para el cultivo de plántulas de cagaita. Además, la coinoculación proporciona un mayor contenido de Fe, Mg y K en las hojas, como mostró este trabajo.

ABSTRACT Hepatitis E Virus (HEV) is an infection known worldwide for its asymptomatic and self-limited course in most cases. Some cases progressing to chronicity have been described in immunosuppressed patients, especially in recipients of solid organ transplants. We evaluated laboratory parameters of HEV infection (HEV RNA, anti-HEV IgM and anti-HEV IgG) through enzyme-linked immunosorbent assay (Elisa), confirmed by immunoblotting, in a cohort of 294 patients who received liver transplants at the HCFMUSP (Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo). Laboratory and demographic data were collected from the entirety of the transplanted population. Hepatic biopsies of 122 patients transplanted due liver failure secondary to hepatitis C (HCV), with or without serological or molecular markers of HEV, were analyzed according to METAVIR score. Out of 24 (8.2%) patients tested positive for anti-HEV IgG, six (2%) were positive for anti-HEV IgM and 17 (5.8%) for HEV RNA. Of the patients transplanted because of HCV infection, 95 (77.8%) had received treatment including ribavirin for at least six months before blood sample collection. Among patients transplanted due to HCV cirrhosis who tested positive for anti-HEV IgG, only three (37.5%) showed fibrosis beyond stage 2, while five (41.7%) of the HEV RNA-positive patients had liver fibrosis beyond stage 2. Overall, the prevalence of HEV in the post-hepatic transplant scenario appears to be low, and, at least histologically, seemingly not harmful. We conclude that, although some studies reported a risk of HEV chronification, patients who had their livers transplanted due to HCV and showed serological or molecular markers of HEV did not have higher levels of fibrosis compared to patients who showed no indications of HEV infection at the time of the analysis.

Abstract During grain storage, a considerable amount of product is lost because of insects, such as Zabrotes subfasciatus. Currently, to mitigate these risks, studies are searching for plants with potential for the control of agricultural pests, also known as botanical insecticides. In this study, the fumigant toxicity of the essential oils of Piper callosum (PC-EO), Piper marginatum (PM-EO) and Vitex agnus-castus (VA-EO) against Zabrotes subfasciatus was investigated. The essential oils of PC-EO, PM-EO and VA-EO were analysed by gas chromatography (GC-MS), and the major components were 3,4-methylenedioxypropiophenone (10.4%), bicyclogermacrene (10.1%) and germacrene D (9.9%) for PM-EO; safrol (29.3%) for PC-EO; and 1,8-cineol (23.8%) for VA-EO. In fumigation tests, VA-EO killed 100% Zabrotes subfasciatus at a concentration of 0.004 µL/L air after 24 h of treatment, whereas PC-EO and PM-EO at 0.01 µL/L air caused 100% Z. subfasciatus mortality after 48 h. The VA-EO sample provided the lowest LD50 after 24 h (0.17 µL/L air), followed by PC-EO (0.78 µL/L air) and PM-EO (1.17 µL/L air). These results demonstrate that the essential oils of these species can be an alternative to control pests in stored products. This is the first report of the fumigant potential of these species against Z. subfasciatus.

OBJECTIVES: To evaluate the addition of a fourth antiemetic intervention in patients at high risk for postoperative nausea and vomiting (PONV). METHODS: High-risk patients (Apfel score 3 or 4) scheduled for unilateral mastectomy were randomly allocated in one of two groups, oral aprepitant (oral aprepitant 80 mg, intravenous dexamethasone 8 mg, and palonosetron 0.075 mg) and oral placebo (oral placebo, intravenous dexamethasone 4 mg, and palonosetron 0.075 mg). Patients and caregivers were blinded to the group assignments. The primary efficacy endpoints included the incidence of nausea and vomiting, and the secondary endpoints included use of rescue antiemetics during a 48-hour postoperative period. ClinicalTrials.gov: NCT02431286. RESULTS: One hundred patients were enrolled in this study and 91 were analyzed, 48 in group A and 43 in group P. No patient presented with nausea or vomiting in the first 2 hours after surgery. From the 2nd to the 6th hour, the incidence of PONV was 8.33% in group A and 9.30% in group P. In the first 24 hours, the incidence of PONV was 27.08% in the group A and 20.93% in group P. From the 24th to the 48th hour, the incidence of PONV was 8.33% in group A and 13.95% in group P. There were no statistically significant differences in PONV between groups. CONCLUSION: The addition of aprepitant as a third antiemetic resulted in no significant reduction in the incidence of PONV in this population. However, the incidence of PONV was reduced in relation to the general population.

BACKGROUND The evaluation of procedures for drug susceptibility prediction of Mycobacterium tuberculosis based on genomic data against the conventional reference method test based on culture is realistic considering the scenario of growing number of tools proposals based on whole-genome sequences (WGS). OBJECTIVES This study aimed to evaluate drug susceptibility testing (DST) outcome based on WGS tools and the phenotypic methods performed on isolates of M. tuberculosis Lineage 1 from the state of Pará, Brazil, generally associated with low levels of drug resistance. METHODOLOGY Culture based DST was performed using the Proportion Method in Löwenstein-Jensen medium on 71 isolates that had been submitted to WGS. We analysed the seven main genome sequence-based tools for resistance and lineage prediction applied to M. tuberculosis and for comparison evaluation we have used the Kappa concordance test. FINDINGS When comparing the WGS-based tools against the DST, we observed the highest level of agreement using TB-profiler. Among the tools, TB-profiler, KvarQ and Mykrobe were those which identified the largest number of TB-MDR cases. Comparing the four most sensitive tools regarding resistance prediction, agreement was observed for 43 genomes. MAIN CONCLUSIONS Drug resistance profiling using next-generation sequencing offers rapid assessment of resistance-associated mutations, therefore facilitating rapid access to effective treatment.

Resumo O rápido crescimento populacional impulsionado pela indústria do petróleo no município de Macaé/RJ, a fiscalização ineficiente e a especulação imobiliária motivaram ocupações ilegais de espaços territoriais especialmente protegidos, como os manguezais estuarinos do Rio Macaé. Objetiva-se comparar as condições de vulnerabilidade socioeconômica e ambiental que caracterizam essas ocupações à luz dos Objetivos de Desenvolvimento Sustentável (ODS) 1 e 6 da Agenda 2030 da Organização das Nações Unidas: erradicação da pobreza; e acesso à água potável e ao saneamento, respectivamente. Dada a necessidade de construção de indicadores, para acompanhar o cumprimento das metas associadas aos ODS, propõe-se a aplicação do Índice de Pobreza Hídrica, adaptado às comunidades Ilha Colônia Leocádia e Ilha da Caieira, visando comparar o estado socioambiental dessas ocupações em termos de aderência a condições promotoras de sustentabilidade para a região. Um questionário semiestruturado foi aplicado aos moradores das localidades e os resultados permitiram estimar o IPH, confirmando a situação de grave pobreza hídrica e de vulnerabilidade socioeconômica dos moradores da Ilha Colônia Leocádia em relação aos da Ilha da Caieira. Isto indica uma realidade que caminha na contramão da Agenda 2030 e necessita de políticas públicas promotoras do bem-estar dos estuarinos, focadas no acesso à água, na proteção dos recursos hídricos e nas soluções baseadas na natureza.

Abstract The rapid population growth driven by the petroleum industry in the city of Macaé/RJ, inefficient control mechanisms and land speculation motivated illegal occupations of specially protected territorial spaces, such as Macaé river’s mangroves. The objective is to compare the conditions of socio-economic and environmental vulnerability that characterize these occupations in the light of the Sustainable Development Goals (SGD) 1 and 6 of the 2030 Agenda : poverty eradication; access to drinking water and sanitation. Given the need to construct indicators, to monitor compliance with the goals associated with SGDs, the application of the Water Poverty Index (WPI) is proposed, adapted to the Communities colony Leocádia Island and Caieira’s Island, aiming to compare the state Environmental impacts of these occupations in terms of adherence to sustainability-promoting conditions for this region. A semi-structured questionnaire was applied to residents of the localities and the results allowed WPI estimation, confirming the situation of severe water poverty and socio-economic vulnerability of the residents of the island of colony Leocádia compared to the island of Caieira, indicating a reality that goes against the 2030 Agenda, demanding public policies promoting estuarine population’s well-being, focused on access to water, protection of hydrous resources and solutions based on nature.
