    Abstract There are large differences in the shape and size of regional SARS-CoV-2 epidemics in Brazil. Here we tested monthly blood donation samples for IgG antibodies from March 2020 to March 2021 in eight of Brazil’s most populous cities. There was large variation in the inferred attack rate adjusted for seroreversion across cities, and seroprevalence was consistently smaller in women and donors older than 55 years. The age-specific infection fatality rate differed between cities and consistently increased with age. The infection hospitalisation rate (IHR) increased significantly during the gamma-dominated second wave in Manaus, suggesting increased morbidity of the Gamma VOC compared to previous variants circulating in Manaus. The higher disease penetrance associated with the health system’s collapse increased the overall IFR by a minimum factor of 2.91 (95% CrI 2.43–3.53). These results demonstrate large heterogeneity in epidemic spread and highlight the utility of blood donor serosurveillance to monitor SARS-CoV-2 epidemics.

    Resumo Objetivou-se verificar a adesão às medidas de prevenção em idosos com maior predisposição a formas graves de COVID-19 e sua associação e interação com o apoio social. Trata-se de um estudo transversal realizado em amostra de 3.477 participantes do inquérito telefônico do Estudo Longitudinal da Saúde dos Idosos Brasileiros (iniciativa ELSI-COVID-19), que informaram ter saído de casa na semana anterior à realização do inquérito. A adesão foi aferida pela frequência com que saiu de casa, necessidade de sair de casa, uso de máscara e higienização das mãos. As análises basearam-se no modelo Poisson com variância robusta. Idade ≥ 65 anos, hipertensão, diabetes e obesidade foram considerados fatores predisponentes para formas graves de COVID-19. O apoio social incluiu o arranjo domiciliar e a conexão social na pandemia. Aproximadamente 46% apresentaram melhor adesão, que foi associada positivamente ao número de fatores predisponentes para formas graves. O apoio social não foi associado à adesão e não modificou essa associação, após ajustamentos. Conclui-se que a adesão às medidas de prevenção, que deveria ser estendida a todos, está concentrada nos idosos com maior predisposição a formas graves de COVID-19, independentemente do apoio social.

    Food losses and waste (FLW) is considered a critical issue in the ongoing debate on the sustainability of agri-food systems. However, the scholarly literature on FLW is still geographically-biased, with more attention devoted to developed countries, even in Europe. In this context, this article analyses the state of research on FLW in the Western Balkan region (viz. Bosnia and Herzegovina, Croatia, Montenegro, North Macedonia, and Serbia). A search performed in October 2021 on the Web of Science database returned 34 documents, and 21 eligible ones were included in the systematic review. The topical analysis of the literature addressed causes of FLW, stages of the food supply chain, extent and magnitude of FLW, FLW and food security, economic and environmental impacts of FLW, and food waste (FW) management strategies. A central finding was the scarcity of data on FW in the Western Balkans. Moreover, the literature focused on FW at the consumer level, while food loss at other stages of the food chain was generally overlooked. There is a lack of comprehensive analyses of the economic and environmental impacts of FLW as well as its implications in terms of food and nutrition security. The quantification of FLW is generally inaccurate and based on estimates and self-reported data. The literature focuses on FW reuse and recycling (e.g., energy, compost) while other management strategies (e.g., reduction/prevention, redistribution) are rarely addressed. However, the results indicated that consumers in the Western Balkans pay attention to the FW issue, especially during the COVID-19 pandemic, which is an encouraging sign that can be exploited in awareness-raising campaigns and education activities. Meanwhile, research on FLW in the Western Balkans is highly needed to fill the identified knowledge gap and provide evidence to policies dealing with the transition to sustainable food systems in the region.

    There is a great demand for optimization of high performance composite structures, particularly in the aerospace sector. To avoid vibrational resonance in aerospace and naval structures, laminated plates can be designed using fundamental frequency constraints. Composite panels are particularly attractive because the vibration response can be optimised by tailoring the fibre angles of different layers without incurring weight penalties. A viable alternative is to use circumferential and radial layers for optimizing fundamental frequencies. This work focuses on the application these two types of theoretical layers and investigating its efficiency, for plates with and without cutouts.

    The new coronavirus (COVID-19) is a viral disease that was classified as a pandemic situation on a global scale in early 2020. Severe Acute Respiratory Syndrome (SARS-CoV)-2 has the enzyme Mpro, until then, best characterized as an important biological target for intracellular viral replication. To investigate the interactions between curcumins and other compounds derived from cinnamic acid with the SARS-CoV-2 Mpro protease as well as to infer their physicochemical and drug-like properties, four natural curcumins and eight related compounds were selected for in silico screening, of molecular docking with the biological target Mpro, to suggest a therapeutic method associated with antiSARS-CoV-2 drugs, such as anakinra, azithromycin, baricitinib, hydroxychloroquine and remdesivir. All curcumins and related compounds can act as synergistic inhibitors of the main viral protein in SARS-CoV-2. The curcumins and other compound ligands showed similar interactions with the enzyme comparable to the control ligands. The ligands capsaicin, dehydrozingerol, dibenzoylmethane and isoeugenol stand out, due to their strong interactions. Among the compounds tested in this study, capsaicin, an alkaloid that is obtained from the fruits of plants of the genus Capsicum, showed significant activity in terms of its potential to inhibit SARS-CoV-2 viral replication.

    ABSTRACTAs the worldwide vaccination, it is imperative to minimize vaccine wastage by effectively using all doses available. Vaccine wastage can occur at multiple points during the vaccination process, but it is mainly because the device dead space and the filling process technique. However, there are no studies discussing the waste volume effect of COVID-19 vaccines in clinical practice. There is an increasing COVID-19 vaccine demand that we estimate up to several billion dual doses. The objective of this study was to assess the number of 0.3mL doses obtained from a multiple-dose vial using 1ml and 3ml syringes with different type of needles replicating the first COVID-19 vaccination protocol.Our results suggest that it is possible to obtain six or seven doses from each vial instead five. We provide evidence to optimize between 20% and 40% additional vaccine doses per vial if the current 5-dose vials are used, making scarce supplies go further.It is our duty, as researchers, to ensure the efficacy and efficiency of the worldwide COVID-19 vaccination process. However, if standard syringes-needles and technique are used, there may not be sufficient volume to draw extra doses from a single vial.

    ABSTRACT In the light of Piketty’s Capital et idéologie, this article reflects on Brazil’s regressive tax structure and the crises induced by the Covid-19 pandemic. We present programmatic aspects of the book, anticipating how its tax justice proposals would be received in the Brazilian public debate. We question whether the current crises provide an opportunity for discussing structural changes like the reversal of the Brazilian tax structure.

    Data on the etiologies of pneumonia among children are inadequate, especially in developing countries. The principal objective is to undertake a multicenter incident case-control study of5-year-old children hospitalized with pneumonia in developing and emerging countries, aiming to identify the causative agents involved in pneumonia while assessing individual and microbial factors associated with the risk of severe pneumonia.A multicenter case-control study, based on the GABRIEL network, is ongoing. Ten study sites are located in 9 countries over 3 continents: Brazil, Cambodia, China, Haiti, India, Madagascar, Mali, Mongolia, and Paraguay. At least 1,000 incident cases and 1,000 controls will be enrolled and matched for age and date. Cases are hospitalized children5 years with radiologically confirmed pneumonia, and the controls are children without any features suggestive of pneumonia. Respiratory specimens are collected from all enrolled subjects to identify 19 viruses and 5 bacteria. Whole blood from pneumonia cases is being tested for 3 major bacteria. S. pneumoniae-positive specimens are serotyped. Urine samples from cases only are tested for detection of antimicrobial activity. The association between procalcitonin, C-reactive protein and pathogens is being evaluated. A discovery platform will enable pathogen identification in undiagnosed samples.This multicenter study will provide descriptive results for better understanding of pathogens responsible for pneumonia among children in developing countries. The identification of determinants related to microorganisms associated with pneumonia and its severity should facilitate treatment and prevention.

    Tem-se por objetivo mapear as políticas da Rede Estadual de Educação do Rio de Janeiro na oferta de atividades pedagógicas não presenciais durante a primeira onda da Covid-19, analisando as condições de trabalho docente nesse período. Trata-se de estudo exploratório, com 22 professores atuantes em turmas de Ensino Médio. A coleta de dados foi realizada através de aplicação de questionário remoto, com estrutura de respostas semiestruturadas e fechadas. Os resultados parciais apontaram para baixa frequência de políticas públicas nacionais de regulamentação do acesso remoto, sendo predominantes políticas descentralizadas pelas Unidades da Federação. Os docentes apontaram para discrepâncias entre políticas públicas anunciadas pelo governo do estado e sua efetivação.

    Abstract There are large differences in the shape and size of regional SARS-CoV-2 epidemics in Brazil. Here we tested monthly blood donation samples for IgG antibodies from March 2020 to March 2021 in eight of Brazil’s most populous cities. There was large variation in the inferred attack rate adjusted for seroreversion across cities, and seroprevalence was consistently smaller in women and donors older than 55 years. The age-specific infection fatality rate differed between cities and consistently increased with age. The infection hospitalisation rate (IHR) increased significantly during the gamma-dominated second wave in Manaus, suggesting increased morbidity of the Gamma VOC compared to previous variants circulating in Manaus. The higher disease penetrance associated with the health system’s collapse increased the overall IFR by a minimum factor of 2.91 (95% CrI 2.43–3.53). These results demonstrate large heterogeneity in epidemic spread and highlight the utility of blood donor serosurveillance to monitor SARS-CoV-2 epidemics.

    Resumo Objetivou-se verificar a adesão às medidas de prevenção em idosos com maior predisposição a formas graves de COVID-19 e sua associação e interação com o apoio social. Trata-se de um estudo transversal realizado em amostra de 3.477 participantes do inquérito telefônico do Estudo Longitudinal da Saúde dos Idosos Brasileiros (iniciativa ELSI-COVID-19), que informaram ter saído de casa na semana anterior à realização do inquérito. A adesão foi aferida pela frequência com que saiu de casa, necessidade de sair de casa, uso de máscara e higienização das mãos. As análises basearam-se no modelo Poisson com variância robusta. Idade ≥ 65 anos, hipertensão, diabetes e obesidade foram considerados fatores predisponentes para formas graves de COVID-19. O apoio social incluiu o arranjo domiciliar e a conexão social na pandemia. Aproximadamente 46% apresentaram melhor adesão, que foi associada positivamente ao número de fatores predisponentes para formas graves. O apoio social não foi associado à adesão e não modificou essa associação, após ajustamentos. Conclui-se que a adesão às medidas de prevenção, que deveria ser estendida a todos, está concentrada nos idosos com maior predisposição a formas graves de COVID-19, independentemente do apoio social.

    Food losses and waste (FLW) is considered a critical issue in the ongoing debate on the sustainability of agri-food systems. However, the scholarly literature on FLW is still geographically-biased, with more attention devoted to developed countries, even in Europe. In this context, this article analyses the state of research on FLW in the Western Balkan region (viz. Bosnia and Herzegovina, Croatia, Montenegro, North Macedonia, and Serbia). A search performed in October 2021 on the Web of Science database returned 34 documents, and 21 eligible ones were included in the systematic review. The topical analysis of the literature addressed causes of FLW, stages of the food supply chain, extent and magnitude of FLW, FLW and food security, economic and environmental impacts of FLW, and food waste (FW) management strategies. A central finding was the scarcity of data on FW in the Western Balkans. Moreover, the literature focused on FW at the consumer level, while food loss at other stages of the food chain was generally overlooked. There is a lack of comprehensive analyses of the economic and environmental impacts of FLW as well as its implications in terms of food and nutrition security. The quantification of FLW is generally inaccurate and based on estimates and self-reported data. The literature focuses on FW reuse and recycling (e.g., energy, compost) while other management strategies (e.g., reduction/prevention, redistribution) are rarely addressed. However, the results indicated that consumers in the Western Balkans pay attention to the FW issue, especially during the COVID-19 pandemic, which is an encouraging sign that can be exploited in awareness-raising campaigns and education activities. Meanwhile, research on FLW in the Western Balkans is highly needed to fill the identified knowledge gap and provide evidence to policies dealing with the transition to sustainable food systems in the region.
