ABSTRACT Objectives: To verify the association between the ABO blood type and the risk of SARS-CoV-2 infection and COVID-19 disease severity. Methods: This review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), using the 2020 PRISMA Checklist and flow diagram, and articles selected for review were analyzed using the Newcastle-Ottawa Quality Rating Scale. The research question was: "Would the ABO blood group influence the risk of infection and clinical course of patients infected with SARS-CoV-2?", The following databases were used: Embase, PubMed, Virtual Health Library (VHL), Web of Science, Science-Direct and Scopus. The protocol for this review was registered in the Prospective Register of Systematic Reviews (PROSPERO), number CRD42021245945. Results: We found 798 articles across PubMed, Embase, Scopus, Web of Science, Science Direct and Virtual Health Library and 54 articles were included in the final analysis. Among 30 studies evaluating the risk of COVID-19 infection, 21 found significant correlations with ABO blood groups, 14 of them revealing an increased risk in blood group A and 15 studies showing a decreased risk in blood group O. Most studies found no significant correlation with disease severity or mortality. Conclusion: The qualitative assessment of available information suggests that blood group A may be a risk factor for COVID-19 infection and that blood group O may have a protective effect. We were unable to determine a clear association between the ABO blood group and mortality. These conclusions are based on highly heterogenous evidence.

Abstract Purpose This paper demonstrates that the effects of the presence of outside directors on the board of directors can be different across family vs. non-family firms, regarding the financial performance. We propose that the presence of outside directors in the board is relevant to explain the performance of family firms, because they better deal with mechanisms that reduce the type II agency conflicts. Theoretical framework Based on agency theory and its derivatives, we capture the specificities of family firms relative to non-family firms. Design/methodology/approach Drawing from an extensive and updated database of over 370 publicly listed companies in Brazil, this study conducted panel data regressions with fixed effects on three different response variables, in order to have a broader perspective and reduce the bias of the results. Moreover, we performed robustness tests with different measurement methods. In addition, we tested the selection of variables by addressing both internal and external validity criteria, in addition to convergent and nomological validity, according to the literature. Findings The empirical results indicate that there is a relationship between board independence and short-term financial performance for a cohort of family firms. Practical & social implications of research This research contributes to various stakeholders by providing relevant insights about an important ESG criterion, which opens up a path for further studies. Originality/value - This is a novel approach to relevant phenomena from the perspective of family firms compared to non-family firms. Also, this paper deepens the study of family businesses and considers different cohorts of firms.

ABSTRACT Introduction: Although still rare, pulmonary embolism (PE) in children has been increasing over the years. Data regarding this group of patients are still sparse, which contributes to the lack of standardized prophylaxis protocols and the misdiagnosis. This study aimed to determine the incidence of pediatric PE at a Brazilian tertiary hospital, describe clinical characteristics and identify possible risk factors. We also analyzed the diagnosis and management of PE. Methods: This was a retrospective review of tertiary Brazilian single-center data of all pediatric patients (0 – 18 years) with acute PE, diagnosed radiologically, from September 2009 to May 2019. Results: The incidence of PE was 3.3 cases per 10,000 hospitalized children. All the twenty-three cases had some risk factor identified and sixteen of them (69.5%) had more than one risk factor. The most important were central venous catheter (39.1%), malignancy (34.8%) and recent surgery (34.8%). Among the children with identifiable symptoms (69.5%), the most common was dyspnea (56.2%). Only one patient did not receive antithrombotic therapy because of the high bleeding risk and most patients (70.6%) were treated for 3 to 6 months. Among the nineteen patients alive at the end of the six-month follow-up, ten (52.6%) repeated the PE image control. Seven of them (70.0%) had complete or partial resolution of the thrombosis and none had worsening images. Conclusion: Our lower incidence than that of the current literature may reflect underdiagnosis due to low suspicion of PE. At least one risk factor was identified in all patients, which emphasizes the importance of increasing awareness of high-risk children.

ABSTRACT Objective: To verify the association between clinical and sociodemographic factors and time spent sitting in military police. Method: This is a cross-sectional study, with 432 military police officers from Eastern Regional Policing Command units of the Military Police of Bahia de Feira de Santana. Data collection took place from August to December 2022 through Google Forms using the International Physical Activity Questionnaire. Results: Men predominated (82.35%), race/color was black (87.04%), the head of the family had completed higher education (47.69%) and police officers with a partner (81.94%). The risk of time spent sitting ≥ 180 minutes per day was lower in males (IRR < 1). Increasing age was associated with a lower risk of time spent sitting ≥ 180 minutes per day (IRR < 1). Conclusion: Male police officers with more years of experience were less exposed to sedentary behavior. Specific interventions and health policies aimed at combating sedentary behavior become relevant, aiming to promote health and prevent diseases.

Abstract: Aim The Aurá River, located in the second-largest Brazilian Amazon city, has been experiencing the effects of human activities from riverine communities and the Aurá landfill for many years. In this study, we assess the occurrence, sources, and distribution of selected sterol markers in surface sediments of Aurá River in order to evaluate the organic matter inputs in this water body. Methods Gas chromatography-tandem mass spectrometry (GC/MS/MS) was used to identify and quantify sterol compounds. Pearson correlation, principal component analysis (PCA) and sterol ratios were used to assess sewage pollution. Results The sterol markers identified, the related diagnostic ratios, and statistical analysis showed that Aurá River sediments presented two primary sterol sources: anthropogenic (domestic sewage and inputs from Aurá landfill) and biogenic sources (terrestrial higher plants). Station 1 (the closest site to the Aurá landfill) presented the highest level of coprostanol (219.8 ng g-1). This maximum level of coprostanol and the sterol ratios indicate moderate human fecal contamination in the upper reach of the Aurá River. Coprostanol levels were similar to the lower to midrange concentrations reported for surficial river sediments around the world. Conclusions This study demonstrated that domestic sewage pollution from riverine communities and organic matter inputs from Aurá landfill might be assumed as potential threats to environmental and human health.

Resumo: Objetivo O rio Aurá, no nordeste da Amazônia brasileira, vem sofrendo influência antrópica de comunidades ribeirinhas e do aterro sanitário Aurá há muitos anos. Neste trabalho, avaliamos a ocorrência, fontes e distribuição de seis marcadores de esteróis em sedimentos superficiais do Rio Aurá para avaliar aportes orgânicos neste corpo d'água. Métodos A cromatografia gasosa-acoplada a espectrometria de massas (GC/MS) foi empregada para determinar os esteróis. A análise de correlação de Pearson, análise de componentes principais (PCA) e razões de esteróis foram utilizadas para avaliar a poluição por esgoto. Resultados Os analitos de interesse identificados e as razões diagnósticas indicaram que os sedimentos do rio estudado apresentam compostos orgânicos provenientes de fontes tanto antropogênicas (esgotos domésticos e MO do aterro sanitário) quanto biogênicas autóctones (plantas superiores terrestres). A Análise de Componentes Principais (PCA) corrobora com esse resultado e possibilitou o agrupamento dos pontos de amostragem segundo essas fontes. A estação 1 (ponto mais próximo do aterro Aurá) apresentou o maior nível de contaminação observado e o coprostanol foi detectado em maior concentração 219,8 ng g-1 nesse local, o que indica contaminação fecal humana moderada. Conclusões Este trabalho demonstrou que a poluição por esgoto doméstico e insumos de MO do aterro do Aurá podem ser ameaças potenciais ao ecossistema e à saúde humana da região estudada.

Abstract The objective of this work was to use the GGE biplot method to select superior wheat genotypes for adaptability and stability, and to determine grain yield in Sussundenga, Bárué, and Lichinga, in Mozambique, in the 2018/2019, 2019/2020, and 2020/2021 crop years. Eleven treatments were evaluated, using ten wheat genotypes from International Maize and Wheat Improvement Center and a control cultivar developed by a Zimbabwean seed company and used in the national wheat program of the country. Grain yield was the main trait evaluated through individual and joint analyses of variance, adaptability, and stability. The effects of genotypes and the genotype × environment interaction were significant. The adaptability and stability analysis using the GGE biplot method showed that the first two main components explained 94.6% of the total variation for year effect, and 91.8%, for the location effect. The following genotypes can be selected for favorable and unfavorable environments: G1, considered ideal due to its high mean yield and stability over the years; and G4 and G7, for simultaneously showing a high yield and stability over the years.

Resumo O objetivo deste trabalho foi usar o método GGE biplot, para selecionar genótipos de trigo superiores quanto à adaptabilidade e à estabilidade e determinar a produtividade de grãos em Sussundenga, Bárué e Lichinga, em Moçambique, nas safras agrícolas de 2018/2019, 2019/2020 e 2020/2021. Foram avaliados 11 tratamentos, tendo-se utilizado dez genótipos de trigo provenientes do International Maize and Wheat Improvement Center e uma cultivar testemunha, desenvolvida por uma empresa zimbabweana de sementes e usada no programa nacional de trigo do país. A produtividade de grãos foi a principal característica avaliada, por meio de análises individuais e conjuntas de variância, adaptabilidade e estabilidade. Os efeitos dos genótipos e da interação genótipo × ambiente foram significativos. A análise de adaptabilidade e estabilidade pelo método GGE biplot mostrou que os dois primeiros componentes principais explicaram 94,6% da variação total para o efeito ano, e 91,8%, para o efeito localização. Os seguintes genótipos podem ser selecionados para ambientes favoráveis e desfavoráveis: G1, considerado ideal devido sua alta média de produtividade e estabilidade ao longo dos anos; e G4 e G7, por apresentarem, simultaneamente, alta produtividade e estabilidade ao longo dos anos.

Abstract This article develops and validates a Measurement Scale of the Propensity to Entrepreneurship and its Antecedents (MSPEA). The theoretical basis concerns the Propensity to Entrepreneurship and the previous individual characteristics (innovative behavior, need for autonomy, need for achievement, proactivity, self-efficacy, locus of internal/external control, tolerance/intolerance to ambiguity, risk propensity, and risk aversion). The methodological procedures involved the qualitative (selection of individual characteristics and elaboration of items) and quantitative approaches through multivariate data analysis. The results reveal that all constructs meet the necessary parameters for performing Exploratory Factor Analysis (EFA). After reduction, all presented good reliability with Cronbach’s alpha greater than 0.70, indicating that all MSPEA constructs are statistically reliable. In the final version, 56 items remained, 9 of which were of Propensity to Entrepreneurship and 47 of individual characteristics. The elaboration of items to measure the propensity to entrepreneurship and the identification of a set of individual characteristics preceding it expands the understanding of this theme since several studies did not measure it as a construct, which is the main contribution of this study. Considering that EFA is an interdependence technique in which factors are formed to show the explanatory power of a set of variables, not allowing one or more factors to be considered predictors of another factor, future research could perform the Confirmatory Factor Analysis proposing a model of how these antecedent individual characteristics can be directly or indirectly related to the Propensity to Entrepreneurship.

Resumen El objetivo fue desarrollar y validar una escala de medición de la propensión al emprendimiento y sus antecedentes (EMPEA). La base teórica se refiere a la propensión emprendedora y las características individuales previas (comportamiento innovador, necesidad de autonomía, necesidad de logro, proactividad, autoeficacia, locus de control interno/externo, tolerancia/intolerancia a la ambigüedad, propensión al riesgo y aversión al riesgo). Los procedimientos metodológicos son un estudio mixto, utilizando enfoques cualitativos (selección de características individuales y elaboración de ítems) y cuantitativos, a través del análisis multivariado de datos. Los resultados revelan que todos los constructos cumplen con los parámetros necesarios para realizar el análisis factorial exploratorio (AFE). Después de la reducción, todos mostraron una buena confiabilidad con un alfa de Cronbach superior a 0,70, lo que indica que todas los constructos EMPEA son estadísticamente confiables. En la versión final quedaron 56 ítems ‒9 de propensión al emprendimiento y 47 de características individuales‒. La elaboración de ítems para medir la propensión al emprendimiento, así como la identificación de un conjunto de características individuales que la preceden, amplía la comprensión de este tema, ya que varios estudios no lo han medido como constructo, lo cual es el principal aporte del presente estudio. Considerando que el AFE es una técnica de interdependencia en la que se forman factores para mostrar el poder explicativo de un conjunto de variables, no permitiendo que uno o más factores sean considerados predictores de otro factor, las futuras investigaciones podrían realizar un análisis factorial confirmatorio proponiendo un modelo de cómo estas características individuales precedentes pueden estar directa o indirectamente relacionadas con la propensión emprendedora.

Resumo O objetivo foi desenvolver e validar uma Escala de Mensuração da Propensão ao Empreendedorismo e seus Antecedentes (EMPEA). A base teórica diz respeito à Propensão ao Empreendedorismo e às características individuais prévias (comportamento inovador, necessidade de autonomia, necessidade de realização, proatividade, autoeficácia, locus de controle interno/externo, tolerância/intolerância à ambiguidade, propensão ao risco e aversão ao risco). Os procedimentos metodológicos são um estudo misto, utilizando as abordagens qualitativa (seleção de características individuais e elaboração de itens) e quantitativa, por meio de análise multivariada de dados. Os resultados revelam que todos os construtos atendem aos parâmetros necessários para a realização da Análise Fatorial Exploratória (AFE). Após a redução, todos apresentaram boa confiabilidade com alfa de Cronbach maior que 0,70, indicando que todos os construtos do EMPEA são estatisticamente confiáveis. Na versão final, restaram 56 itens, sendo 9 de Propensão ao Empreendedorismo e 47 de características individuais. A elaboração de itens para mensurar a propensão ao empreendedorismo, bem como a identificação de um conjunto de características individuais que o antecedem, amplia o entendimento sobre esse tema, uma vez que diversos estudos não o mensuraram como construto, sendo esta a principal contribuição do presente estudar. Considerando que a AFE é uma técnica de interdependência na qual os fatores são formados para mostrar o poder explicativo de um conjunto de variáveis, não permitindo que um ou mais fatores sejam considerados preditores de outro fator, pesquisas futuras poderiam realizar a Análise Fatorial Confirmatória propondo um modelo de como essas características individuais antecedentes podem estar direta ou indiretamente relacionadas à Propensão ao Empreendedorismo.

RESUMO A internacionalização do ensino superior vem ganhando importância teórica e empírica nas décadas recentes. Nesse contexto, este artigo objetiva descrever e analisar a internacionalização de escolas de negócios a partir das atividades dos acadêmicos e com base nas proposições defendidas pela Teoria da Troca Social (SET, do inglês Social Exchange Theory). Para atingir nosso objetivo, conduzimos 39 entrevistas com acadêmicos de escolas de negócios dos Estados Unidos e do Brasil, incluindo Instituto Tecnológico de Massachusetts (MIT), Harvard, Fundação Getulio Vargas (FGV) e Universidade de São Paulo (USP). Temos como principais achados: (i) existem recompensas individuais que não são abordadas pela SET; (ii) há benefícios para outras partes interessadas que não são contemplados pela SET; (iii) há certas decisões não racionais não previstas pela SET; (iv) e a condição de equivalência entre custos e recompensas prevista pela SET apresenta fragilidades. Com esses resultados, trazemos contribuições teóricas e empíricas para a temática.

ABSTRACT The internationalization of higher education has gained in theoretical and empirical importance in recent decades. In this context, this article aims to describe and analyze the internationalization of business schools from the activities of their academics and based on the propositions defended by the Social Exchange Theory (SET). To achieve our goal we conducted 39 interviews with academics from business schools in the United States and Brazil, including Massachusetts Institute of Technology (MIT), Harvard, Getulio Vargas Foundation (FGV) and University of Sao Paulo (USP). We found that: (i) there are individual rewards that are not addressed by SET; (ii) there are benefits to third parties not covered by SET; (iii) certain non-rational choices are not provided by SET; and (iv) the condition of equivalence between costs and rewards provided by SET has its weaknesses. With these findings we add theoretical and empirical contributions to our theme.

ABSTRACT: The spatial variability of soil organic matter, plant water availability, and soil nitrogen (N) availability are drivers of crop response to mineral N fertilizer. The complex interaction of these factors is responsible for within-field corn and wheat yield variability. The hairy vetch (HV) cover crop is an economic, environmentally friendly, and efficient N source capable of conciliating crop yield and soil health. Nevertheless, the HV effects to mitigate yield gap of management zone (MZ) have not yet been documented. This study evaluated the effects of HV and mineral N fertilization, in single or combined input, on alleviating crop yield gap. The study was carried out in two croplands southern Brazil. The experimental design was a complete randomized block in a split plot having MZ (high, medium, and low yield) and N fertilizer rates. Wheat and corn N uptake and grain yield had a quadratic adjustment with N fertilizer input, but there was a significant MZ effect, where low yield zone (LYZ) was less responsive. Consequently, mineral N fertilization as a single input to mitigate the yield gap in this MZ was not efficient. On the other hand, HV increased corn N uptake and grain yield mainly in LYZ compared to MYZ and HYZ. HV fully mitigated the yield gap between MYZ and HYZ. The combined use of HV and mineral N fertilization rate adjusted according to N legume credit and MZ was an efficient strategy to boost yield, favoring soil health and environmental protection.

RESUMO Este artigo teve como objetivo avaliar as repercussões da Covid-19 e do isolamento social na saúde mental de estudantes do ensino superior no Ceará, Brasil. A amostra foi composta por 3.691 alunos do ensino superior participando de aulas on-line no período de junho a setembro de 2020, que responderam a dois instrumentos: um questionário sociodemográfico e situacional referente à pandemia/isolamento social e o Inventário de Saúde Mental. Os resultados mostraram que 21,2% dos alunos tiveram suas atividades canceladas, sem expectativa de retorno. A maioria, 77,2%, relatou preocupação com a morte de parentes e conhecidos pela Covid-19. O estado geral de saúde mental médio, medido pelo inventário, foi de 48,8. Esse resultado sugere que os alunos tiveram sua saúde mental afetada pelas condições impostas pela pandemia. Assim, as instituições de ensino devem promover estratégias para proteger a saúde mental da comunidade estudantil.

ABSTRACT This article aimed to assess the repercussions of Covid-19 and social isolation on the mental health of higher education students in Ceará, Brazil. The sample consisted of 3,691 higher education students taking online classes from June to September 2020, who answered to two instruments: a sociodemographic and situational profile questionnaire concerning the pandemic/social isolation, and the Mental Health Inventory. The results showed that 21.2% of the students had their activities canceled, with no expected return. The majority, 77.2%, reported concern about the death of relatives and acquittances by Covid-19. The overall state of mental health average measured by the inventory was 48.8. This result suggests that students had their mental health affected by the conditions imposed by the pandemic. Therefore, edu- cational institutions should promote strategies to protect the mental health of the student community.

ABSTRACT Ischemia-reperfusion injury is a pathophysiological event occuring after abdominal organ transplantation, and has a significant influence on prognosis and survival of the graft. It is involved in delaying the primary function or non-functioning of the graft. The objective of this study was to provide information on heat shock protein mechanisms in ischemia-reperfusion injuries in abdominal organ transplantations, and to indicate the possible factors involved that may influence the graft outcome. Several classes of heat shock proteins are part of the ischemia and reperfusion process, both as inflammatory agonists and in protecting the process. Studies involving heat shock proteins enhance knowledge on ischemia-reperfusion injury mitigation processes and the mechanisms involved in the survival of abdominal grafts, and open space to support therapeutic future clinical studies, minimizing ischemia and reperfusion injuries in abdominal organ transplantations. Expression of heat shock proteins is associated with inflammatory manifestations and ischemia-reperfusion injuries in abdominal organ transplantations and may influence graft outcomes.

ABSTRACT This study investigates whether venture capitalists (VCs) influence the internationalization of small firms and whether such impact differs between foreign and domestic VCs. Our findings, based on in-depth interviews with top decision-makers from two VCs and four portfolio ventures, indicate contrasts between the perceptions of VCs and portfolio firms, so that the former claim to have a higher impact than what is perceived by the latter. Additionally, our evidence about the differential impacts of foreign versus domestic VCs runs counter to the literature and suggests that the purported stronger impact of foreign VCs may have been over-emphasized in the literature. Two contingencies are revealed that seem to affect the impact of the VC and of its nationality on the internationalization of investee firms: breadth of the industry (global versus local industries) and firm’s vocation (born global firm versus local leader).
