    A pandemia da COVID-19 exacerbou de modo dramático desigualdades sociais pré-existentes e tornou mais urgente a consciencialização da necessidade de transformação social. Os movimentos sociais para a descolonização do conhecimento e dos sistemas de governança ganharam novo ímpeto assim como as demandas de reparação histórica e de justiça climática, sanitária e alimentar. A reparação histórica tem sido por vezes equacionada apenas em termos de restituição de bens materiais ou de compensação financeira, mas trata-se de uma tarefa bem mais complexa que passa necessariamente por tornar a produção de conhecimento um processo mais envolvente e participativo, dentro e fora da academia, colocando em diálogo diversos saberes com vista à construção de futuros mais justos e inclusivos... The COVID-19 pandemic dramatically exacerbated pre-existing social inequalities and added urgency to the awareness of the need for social transformation. Social movements for the decolonisation of knowledge and governance systems have gained new momentum and the demands for historical reparation and climate, health and food justice. Historical reparation has sometimes been equated only to restitution of material goods or financial compensation. Still, it is a much more complex endeavour that necessarily involves making knowledge production a more engaging and participatory process, inside and outside the academy, linking different knowledge to build fairer and more inclusive futures...

    SARS-CoV-2 transmission occurs mainly indoors, through virus-laden airborne particles. Although the presence and infectivity of SARS-CoV-2 in aerosol are now acknowledged, the underlying circumstances for its occurrence are still under investigation. The contamination of domiciliary environments during the isolation of SARS-CoV-2-infected patients in their respective rooms in individual houses and in a nursing home was investigated by collecting surface and air samples in these environments. Surface contamination was detected in different contexts, both on high and low-touch surfaces. To determine the presence of virus particles in the air, two sampling methodologies were used: air and deposition sampling. Positive deposition samples were found in sampling locations above the patient's height, and SARS-CoV-2 RNA was detected in impactation air samples within a size fraction below 2.5 μm. Surface samples rendered the highest positivity rate and persistence for a longer period. The presence of aerosolized SARS-CoV-2 RNA occurred mainly in deposition samples and closer to symptom onset. To evaluate the infectivity of selected positive samples, SARS-CoV-2 viability assays were performed, but our study was not able to validate the virus viability. The presented results confirm the presence of aerosolized SARS-CoV-2 RNA in indoor compartments occupied by COVID-19 patients with mild symptoms, in the absence of aerosol-generating clinical procedures. © The Author(s) 2022.

    In the last 2 years, the COVID-19 pandemic has spread all over the world, forcing the closure of universities, among other unusual measures in recent history. (1) Background: This work is based on the study HOUSE-ULisbon, a survey carried out during the second confinement (March-May 2021) in Portugal with the collaboration of all the Faculties of the University of Lisbon (UL). The present work aims to explore gender differences in how first-year college students experienced and felt COVID-19 and the second confinement. (2) Methods: A questionnaire was carried out. In total, 976 university students (19.66 years (SD = 4.033); Min = 17 and Max = 65) from the first year of the UL were included, of which 69.5% (n = 678) were female, and 30.5% were male (n = 298). SPSS v. 26 was used for quantitative data and MAXQDA 2020 for qualitative data. (3) Results: Overall, students reported various symptoms of physical and mental discomfort (especially females). Statistically significant differences were found in the problems that could arise from the pandemic, such as the prevalence of higher anxiety and worries by females, and online gaming by males. In coping strategies, differences were found in leisure and family relationships, with greater difficulty on the female side. Social interaction was perceived as difficult or very difficult by both genders. As strategies for future pandemics, they highlighted a concerted effort between the government and media in the transmission of messages to the population, facilitating information, knowledge and adoption of protective behaviors. (4) Conclusions: These results are important data for activating or maintaining resources and services for first-year university students, who in some university institutions were supported during the pandemic by psychological, material (e.g., computers, internet), and financial support measures, which are now diminished or extinct. The impacts on their lives will certainly not be extinguished post-pandemic, and health, education, and public policy measures should be prioritized for this group. These results are important data for activating resources and services for students, informing health and education professionals, and supporting public policies. © 2022 by the authors.

    The pandemic is aggravating health inequalities, particularly mental health inequalities, while revealing the social determinants of these inequalities, including migration as a social determinant that mediates the interaction of social, economic, cultural, institutional, and structural factors with health indicators. Therefore, it is of most relevance to identify the multiple interconnected factors that influence the mental health and well-being of migrant populations. A scoping review was developed to map the research performed in this area and to identify any gaps in knowledge, following the PRISMA extension for scoping reviews. MEDLINE, Scopus, and WHO Global Health research databases on COVID-19 were searched from January 2020 to October 2021. The review followed the inclusion criteria Population/Concept/Context (PCC): Population-Adult International migrants (including refugees, asylum seekers, and undocumented migrants); Concept-determinants of (and factors influencing) mental health and well-being; Context-COVID-19 anywhere in the world. Of the sixty-five selected studies, eleven were from European countries and were the focus of this review with special attention to health inequalities experienced by migrants in Europe. The results cover a diversity of themes related to the effects of COVID-19 on the mental health of migrants (country-level environmental factors, social determinants of mental health, mental health indicators and outcomes), responses (such as solidarity and resilience), populations, and study methods. The evidence found can inform recommendations and interventions focused on health promotion and mitigation of the inequalities accentuated by the pandemic. The study “Equity in health in times of pandemic: assessment of the impact on mental health and well-being of the Brazilian and Cape Verdean population in Portugal (EQUALS4COVID19)”, is supported by a grant by the Asylum, Migration and Integration Fund (PT/2021/FAMI/697). © 2022 by the authors.

    The closure of higher education institutions (HEIs) due to the outbreak of the COVID-19 pandemic led to visible changes in pedagogical practices. With the lockdown, there was ambiguity and disagreement about the workload of teachers and students, and about what to teach and what strategies to select. For most instructors, the first challenge was to recreate the face-to-face experience. Worldwide, most universities have speedily adopted synchronous and asynchronous communication modes. Google Classroom, Microsoft Teams, Cisco, Webex, Zoom, and Moodle were among the most used tools. The present study is based upon a quantitative approach, and it intends to analyse teachers’ perceptions of remote teaching during the first pandemic period. Data were collected through an online questionnaire during June and July 2020. The questionnaire had 27 questions divided into three main sections: sociodemographic characterization, e-Learning strategies, and remote assessment. The study population was teachers of a Portuguese HEI. A random sample was used with 547 participants. The main conclusions show that the less experienced teachers are, the more satisfied they feel with remote classes and remote assessment. On the other hand, the most experienced teachers used more tools during the remote teaching period and developed more strategies to perform remote assessment. Regarding the overall assessment of the emergency remote teaching, the participants consider that it was a positive period, and they were moderately satisfied with remote classes and the strategies and tools used during this period.

    Poster apresentado na 13ª Conferência Lusófona de Ciência Aberta. O estudo pretende contribuir para determinar de que forma a situação decorrente da pandemia de Covid 19, especialmente considerando o ensino remoto emergencial, se refletiu no interesse pela utilização de recursos educacionais abertos (REA). Tendo em atenção que no contexto português, a Universidade Aberta (UAb) é única instituição de ensino que organiza de forma sistemática REA numa comunidade específica do seu repositório institucional, é efetuada uma análise comparativa dos dados de utilização do Repositório, expressos em números e locais de utilização dos conteúdos da comunidade REA, nos períodos antes e durante a situação pandémica, de modo a percecionar a existência de padrões de utilização. Partindo da premissa de que os repositórios institucionais contribuem para a internacionalização do conhecimento e o acesso aberto permite ampliar o papel social das universidades, o estudo reflete ainda sobre a contribuição dos REA para a globalização da ciência e da sua mediação pedagógica, percebida pelas estatísticas de utilização das coleções de REA disponibilizadas pela UAb. A análise dos dados revela a importância do Repositório para aumentar a visibilidade das coleções e o potencial impacto junto da comunidade científica e educacional, nacional e internacional info:eu-repo/semantics/acceptedVersion

    With the start of the Coronavirus (COVID-19) pandemic, the global education system has a faced immense challenges and disruptions resulting in and the necessity for an immediate redesign of teaching and learning in the school context. Face-to-face classroom instruction had to be replaced by ‘emergency remote teaching’, requiring teacher to adapt their daily routines to a new and unprecedented educational reality. Researchers and policymakers worldwide have agreed that, despite the fact that efforts were made to immediately adapt to emergency remote teaching, disadvantaged and vulnerable students may be especially at risk in emergency remote teaching. Given the differences in schooling organization across countries during the COVID-19 pandemic it can be expected that teachers performed inclusive instructional practices significantly different. Against the unpredictable situation, cross-country research has been urgently required to provide data that could inform education policy. Thus, this study explored teachers’ perceptions of supporting at risk students during the first COVID-19 school closures, as well as examining teachers’ inclusive teaching practices in three countries: Germany, Austria and Portugal. ANOVA results revealed important country differences. In general, it appears that teachers in Germany and Austria reported to have implemented less practices to address vulnerable and at-risk students compared to Portuguese teachers. Implications of the results, as well as further lines of research are outlined.

    Cet article vise à faire une analyse exploratoire des mutations observées au sein du secteur hôtelier dans trois villes de trois pays et continents différents. En associant les informations provenant des bases de données officielles, les collectes auprès des établissements hôteliers et pages internet des hôtels aux entretiens conduits auprès des représentants du secteur, les changements observés dans l'offre hôtelière à Lisbonne (Portugal), à Maputo (Mozambique) et à São Paulo (Brésil) sont inventoriés et analysés pour la période comprise entre 2020 et 2021. Les regards croisés sur les différentes sources indiquent la suspension de l'activité et la réduction partielle de l'offre à des fins de réduction les coûts d'exploitation comme stratégies courantes suivies par les hôtels dans les trois villes. Ces deux démarches ont eu des incidences négatives sur l’emploi. Des changements plus structurels, tels que les processus de rebranding et la fermeture définitive des hôtels présentent des variations importantes entre les villes étudiées. L'adoption de différentes mesures par ces trois pays et l'exposition variable de ces derniers au tourisme international peuvent expliquer ces différences. Este artigo tem por objetivo fazer uma análise exploratória das mudanças observadas no setor hoteleiro em três cidades de três países e continentes diferentes. Complementando informação proveniente de bases de dados oficiais, de pesquisa direta junto dos estabelecimentos hoteleiros e dos sites dos hotéis, além de entrevistas com representantes do setor, inventariam-se e analisam-se as mudanças observadas na oferta hoteleira em Lisboa (Portugal), Maputo (Moçambique) e São Paulo (Brasil), entre 2020 e 2021. Os resultados mostram que a suspensão da atividade, com encerramento temporário nos períodos mais críticos da pandemia, e a redução parcial da oferta para diminuir os custos operacionais foram as estratégias mais comuns seguidas pela hotelaria nas três cidades, com consequências como perda de emprego. Outras mudanças de caráter mais estrutural, como processos de rebranding e encerramento definitivo de hotéis, encontraram variações significativas entre as cidades estudadas, o que em parte se deve à adoção de políticas diferentes nos vários países e a exposição variável dessas localidades ao turismo internacional. This paper seeks to do an exploratory analysis of the changes observed in the hotel sector in three cities in three different countries and continents. Joining information from official databases, direct survey in hotels and hotel websites, and interviews with industry representatives, an inventory and analysis of the changes observed in hotel supply in Lisbon (Portugal), Maputo (Mozambique) and São Paulo (Brazil) throughout 2020 and 2021 is made. Results show that suspension of activity, with temporary closure during the most critical periods of the pandemic, and partial reduction of supply to reduce operational costs, were the most common strategies followed by hotels in the three cities, with consequences in job losses. Other changes of a more structural nature, such as rebranding processes and permanent closure of hotels found significant variations among the cities studied. The adoption of different policy measures in the various countries and their varying exposure to international tourism explain partly these differences.

    Inadequate infection control, wound care, and oral hygiene protocols in nursing homes provide challenges to residents’ quality of life. Based on the outcomes from a focus group meeting and a literature search, this narrative review evaluates the current and potential roles of antiseptics within nursing home infection management procedures. We examine contemporary strategies and concerns within the management of meticillin-resistant Staphylococcus aureus (MRSA; including decolonization regimes), chronic wound care, and oral hygiene, and review the available data for the use of antiseptics, with a focus on povidone-iodine. Compared with chlorhexidine, polyhexanide, and silver, povidone-iodine has a broader spectrum of antimicrobial activity, with rapid and potent activity against MRSA and other microbes found in chronic wounds, including biofilms. As no reports of bacterial resistance or cross-resistance following exposure to povidone-iodine exist, it may be preferable for MRSA decolonization compared with mupirocin and chlorhexidine, which can cause resistant MRSA strains. Povidone-iodine oral products have greater efficacy against oral pathogens compared with other antiseptics such as chlorhexidine mouthwash, highlighting the clinical benefit of povidone-iodine in oral care. Additionally, povidone-iodine-based products, including mouthwash, have demonstrated rapid in vitro virucidal activity against SARS-CoV-2 and may help reduce its transmission if incorporated into nursing home coronavirus 2019 control protocols. Importantly, povidone-iodine activity is not adversely affected by organic material, such as that found in chronic wounds and the oral cavity. Povidone-iodine is a promising antiseptic agent for the management of infections in the nursing home setting, including MRSA decolonization procedures, chronic wound management, and oral care.

    Objective: Cerebral venous thrombosis (CVT) caused by vaccine-induced immune thrombotic thrombocytopenia (VITT) is a rare adverse effect of adenovirus-based severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) vaccines. In March 2021, after autoimmune pathogenesis of VITT was discovered, treatment recommendations were developed. These comprised immunomodulation, non-heparin anticoagulants, and avoidance of platelet transfusion. The aim of this study was to evaluate adherence to these recommendations and its association with mortality. Methods: We used data from an international prospective registry of patients with CVT after the adenovirus-based SARS-CoV-2 vaccination. We analyzed possible, probable, or definite VITT-CVT cases included until January 18, 2022. Immunomodulation entailed administration of intravenous immunoglobulins and/or plasmapheresis. Results: Ninety-nine patients with VITT-CVT from 71 hospitals in 17 countries were analyzed. Five of 38 (13%), 11 of 24 (46%), and 28 of 37 (76%) of the patients diagnosed in March, April, and from May onward, respectively, were treated in-line with VITT recommendations (p < 0.001). Overall, treatment according to recommendations had no statistically significant influence on mortality (14/44 [32%] vs 29/55 [52%], adjusted odds ratio [OR] = 0.43, 95% confidence interval [CI] = 0.16-1.19). However, patients who received immunomodulation had lower mortality (19/65 [29%] vs 24/34 [70%], adjusted OR = 0.19, 95% CI = 0.06-0.58). Treatment with non-heparin anticoagulants instead of heparins was not associated with lower mortality (17/51 [33%] vs 13/35 [37%], adjusted OR = 0.70, 95% CI = 0.24-2.04). Mortality was also not significantly influenced by platelet transfusion (17/27 [63%] vs 26/72 [36%], adjusted OR = 2.19, 95% CI = 0.74-6.54). Conclusions: In patients with VITT-CVT, adherence to VITT treatment recommendations improved over time. Immunomodulation seems crucial for reducing mortality of VITT-CVT.
