Abstract
Purpose
The purpose of this study is to evaluate the effects of prebiotic, probiotic and synbiotic supplementation on liver histopathology and TLR-4, NFκB and TNF-α gene expression involved in the inflammatory cascade and pathogenesis of experimental nonalcoholic fatty liver disease (NAFLD).
Design/methodology/approach
Wistar male adult rats (n = 40) were submitted to hypercholesterolemic conditions (60 days). On Day 30 of hypercholesterolemic conditions, rats were subdivided in five groups: negative control (NC), positive control (PC), prebiotic (PRE), probiotic (PRO) and synbiotic (SYN). All rats were sacrificed on Day 60. Liver tissue was used to verify histopathological changes and gene expression. Gene expression of TLR-4, TNF-α and NFκB was evaluated in liver tissue using RT-qPCR.
Findings
Histopathological analysis: PC showed more changes than NC, and PRE and SYN showed fewer alterations than PC. Gene expression analysis: PRE showed higher TLR-4, and NFκB and TNF-α compared to PC. Also, PRE showed higher TLR-4 when compared to PRO and SYN. SYN group revealed higher TLR-4 and NFκB expressions compared to PC. PRO group also showed higher NFκB expression compared to PC.
Originality/value
NAFLD is a significant health concern, and it found that prebiotic, probiotic and synbiotic supplementation could have positive effects as a nonpharmacological approach to control this disease.

Abstract
Purpose
This study aims to estimate the overall SARS-CoV-2 seroprevalence and evaluate the accuracy of an antibody rapid test compared to a reference serological assay during a COVID-19 outbreak in a prison complex housing over 13,000 prisoners in Brasília.
Design/methodology/approach
The authors obtained a randomized, stratified representative sample of each prison unit and conducted a repeated serosurvey among prisoners between June and July 2020, using a lateral-flow immunochromatographic assay (LFIA). Samples were also retested using a chemiluminescence enzyme immunoassay (CLIA) to compare SARS-CoV-2 seroprevalence and 21-days incidence, as well as to estimate the overall infection fatality rate (IFR) and determine the diagnostic accuracy of the LFIA test.
Findings
This study identified 485 eligible individuals and enrolled 460 participants. Baseline and 21-days follow-up seroprevalence were estimated at 52.0% (95% CI 44.9–59.0) and 56.7% (95% CI 48.2–65.3) with LFIA; and 80.7% (95% CI 74.1–87.3) and 81.1% (95% CI 74.4–87.8) with CLIA, with an overall IFR of 0.02%. There were 78.2% (95% CI 66.7–89.7) symptomatic individuals among the positive cases. Sensitivity and specificity of LFIA were estimated at 43.4% and 83.3% for IgM; 46.5% and 91.5% for IgG; and 59.1% and 77.3% for combined tests.
Originality/value
The authors found high seroprevalence of anti-SARS-CoV-2 antibodies within the prison complex. The occurrence of asymptomatic infection highlights the importance of periodic mass testing in addition to case-finding of symptomatic individuals; however, the field performance of LFIA tests should be validated. This study recommends that vaccination strategies consider the inclusion of prisoners and prison staff in priority groups.

Abstract
We present a critical literature review debating Brazilian research on social and environmental accounting (SEA). The aim of this study is to understand the role of politics in the construction of hegemonies in SEA research in Brazil. In particular, we examine the role of hegemony in relation to the co-option of SEA literature and sustainability in the Brazilian context by the logic of development for economic growth in emerging economies. The methodological approach adopts a post-structural perspective that reflects Laclau and Mouffe’s discourse theory. The study employs a hermeneutical, rhetorical approach to understand and classify 352 Brazilian research articles on SEA. We employ Brown and Fraser’s (2006) categorizations of SEA literature to help in our analysis: the business case, the stakeholder–accountability approach, and the critical case. We argue that the business case is prominent in Brazilian studies. Second-stage analysis suggests that the major themes under discussion include measurement, consulting, and descriptive approach. We argue that these themes illustrate the degree of influence of the hegemonic politics relevant to emerging economics, as these themes predominantly concern economic growth and a capitalist context. This paper discusses trends and practices in the Brazilian literature on SEA and argues that the focus means that SEA avoids critical debates of the role of capitalist logics in an emerging economy concerning sustainability. We urge the Brazilian academy to understand the implications of its reifying agenda and engage, counter-hegemonically, in a social and political agenda beyond the hegemonic support of a particular set of capitalist interests.

Abstract
Purpose
This paper aims to develop a cross-border regional brand management model to help enhance cooperation for developing such localities. It analyzed its applicability in the Brazil–Argentina and Italy–Austria cross-border regions comprising several cities.
Design/methodology/approach
A systematic literature review was conducted to obtain a theoretical basis and select elements for creating the cross-border regional brand management (CRBM) model. To apply the model, in-depth interviews were conducted with 19 specialists of different nationalities and distinct expertise on cross-border governance and regional branding. In addition, to validate the proposed model, a focus group was carried out, and specialists were consulted using forms, providing 22 additional opinions.
Findings
The results show good managerial practices and gaps that must be overcome to create and manage the brands from the two regions analyzed.
Research limitations/implications
The theoretical contributions consist in extending the literature in place branding by presenting the first CRBM model and the conceptual explanation of each of the model's elements.
Practical implications
The study's practical implications occur through the suggestion of good management practices for the studied localities arising from the applicability of the CRBM model. Furthermore, it is expected that the model developed can be applied in other locations, bringing practical contributions to the management and creation of cross-border regional brands in other countries.
Originality/value
This study presents the first CRBM model and its applicability to two cross-border regions.

Abstract
This chapter addresses the profession of research management and administration (RMA) in Portugal. It starts with a brief outline of the national research and innovation (R&I) ecosystem that contextualises the development of the profession. The RMA community is characterised and the expectations for the future of the RMA profession are summarised using data collected through a national online survey. It is posited that RMA in Portugal is an emergent career having developed key traits of a profession, namely common interests and practices, a concern with deepening specialised knowledge and skills, the existence of an organised network of practitioners, the offer of academic qualifications and training in the area, and the integration in international RMA communities of practice. Nevertheless, future developments in the European Research Area (ERA) are identified as a critical milestone that will influence the development and formal legislative institutionalisation of the RMA profession in Portugal.
