    Marco contextual: La crisis provocada por la pandemia de la COVID-19 produjo cambios en la vida académica de los estudiantes de educación superior, que pueden afectar su bienestar psicológico. Objetivo: Analizar la relación entre las estrategias de afrontamiento utilizadas y el bienestar psicológico en estudiantes de enfermería durante la cuarentena por la COVID-19. Metodología: Estudio transversal, descriptivo-correlacional, con una muestra de 136 estudiantes. La recopilación de datos se realizó en línea mediante la Escala de Medición de la Manifestación del Bienestar Psicológico y el Brief COPE. Resultados: Los estudiantes de los últimos cursos utilizan con más frecuencia la estrategia de afrontamiento apoyo instrumental (p = 0,015) y emocional (p = 0,009), y también tienen mayores niveles de bienestar psicológico (p = 0,012). Los cambios en los ingresos familiares se asocian con el bienestar psicológico (p = 0,024), así como con las estrategias de afrontamiento religión (r = 0,36; p ≤ 0,01), reinterpretación positiva (r = 0,47; p ≤ 0,01) y estado de ánimo (r = 0,37; p ≤ 0,01). Conclusión: Las estrategias de afrontamiento adoptadas por los estudiantes parecen estar relacionadas con el bienestar psicológico durante la cuarentena. Background: The COVID-19 pandemic crisis has brought about changes in the lives of higher education students that may influence their psychological well-being. Objective: To analyze the association between nursing students’ coping strategies and their psychological well-being during the COVID-19 quarantine. Methodology: Cross-sectional, descriptive-correlational study using a convenience sample of 136 students. Data were collected online using the Portuguese version of the Échelle de Mesure des Mani-festations du Bien-être Psychologique and the Brief COPE. Results: Students in the last years of their undergraduate studies used the instrumental support (p = 0.015) and emotional support (p = 0.009) coping strategies more often and had higher levels of psychological well-being (p = 0.012). Psychological well-being is associated with household income changes (p = 0.024), as well as with religion (r = 0.36; p ≤ 0.01), positive reframing (r = 0.47; p ≤ 0.01), and humor (r = 0.37; p ≤ 0.01) coping strategies. Conclusion: Students’ coping strategies seem to be associated with their psychological well-being during the COVID-19 quarantine.

    After explaining the meaning of SARS-CoV2, the protection rules for the disease caused by this virus are described in order to eradicate the resulting pandemic. Methods to differentiate asymptomatic from symptomatic patients will be mentioned. Human lungs, heart, kidney, endothelium and erythrocyte have specific binding sites for the SARS-CoV2. The aim of this opinion was to highlight some new disposable technology to identify two cell properties. One of them is the vascular endothelial cell (EC) receptor binding to the SARS-CoV2 and the other is related with red blood cells (RBCs) as SARS-CoV2 carrier. © 2021 – IOS Press.

    COVID-19 was responsible for devastating social, economic, and political effects all over the world. Although the health authorities imposed restrictions provided relief and assisted with trying to return society to normal life, it is imperative to monitor people’s behavior and risk factors to keep virus transmission levels as low as possible. This article focuses on the application of deep learning algorithms to detect the presence of masks on people in public spaces (using RGB cameras), as well as the detection of the caruncle in the human eye area to make an accurate measurement of body temperature (using thermal cameras). For this task, synthetic data generation techniques were used to create hybrid datasets from public ones to train state-of-the-art algorithms, such as YOLOv5 object detector and a keypoint detector based on Resnet-50. For RGB mask detection, YOLOv5 achieved an average precision of 82.4%. For thermal masks, glasses, and caruncle detection, YOLOv5 and keypoint detector achieved an average precision of 96.65% and 78.7%, respectively. Moreover, RGB and thermal datasets were made publicly available. R&D Project funded by P2020 & mdash;COVID19, with number 70289.

    As práticas de ativismo coletivo, ou ação sociopolítica fundamentada, são uma estratégia pedagógica cada vez mais valorizada na área das Ciências da Educação, por potenciar a capacitação e empoderamento dos alunos para uma cidadania ativa e democrática e a atuação responsável face às questões sociocientíficas e socioambientais que caracterizam a sociedade. O presente estudo centra-se nas potencialidades educativas do desenvolvimento de exposições interativas on-line, sobre imunidade e controlo de doenças, como estratégia de ativismo em tempos de pandemia. Seguindo uma abordagem qualitativa e um paradigma interpretativo, relata o trabalho desenvolvido com uma turma de 28 alunos do 12.º ano, no âmbito da disciplina de Biologia. A intervenção teve por base a teoria socioconstrutivista da aprendizagem e três etapas principais: a pré-produção, produção e pós-produção de uma exposição científica, neste caso designada Pharmaction. Especificamente, pretendeu-se valorizar o conhecimento científico como meio de promoção da saúde, divulgar informação e mobilizar a comunidade a agir na adoção de comportamentos responsáveis, dado existirem doenças e desequilíbrios imunitários. Por se concretizar no contexto de ensino a distância, devido à COVID-19, a exposição foi on-line e construída por meio de ferramentas da Web 2.0. Os dados obtidos, através de inquéritos, observação e análise documental, apontam o potencial educativo da estratégia. Os alunos ampliaram várias competências transversais, destacando-se as competências para a ação, no domínio do ativismo, além de aprendizagens significativas sobre o tema estudado. Apesar das dificuldades na colaboração, pesquisa e gestão de tempo, a turma achou uma forma única, desafiante e motivadora de aprender ciência e, à semelhança dos visitantes, uma boa estratégia de ativismo que beneficiou do recurso às TIC.

    El uso de la narrativa transmedia o storytelling (como se escribe en inglés) en el periodismo, además de corresponder a un modelo de negocio impulsado por la convergencia en los medios de comunicación contemporáneos, puede considerarse una forma de sumergir al público en el universo informativo. En tiempos de pandemia por Covid-19, la cobertura teleperiodística en Brasil refuerza que el periodismo no debe ser sólo declarativo, siendo insuficiente sólo para invertir en estadísticas e informar de estudios científicos en todo el mundo. En este sentido, la narrativa transmedia emerge como una probable propuesta capaz de permitir la inmersión de la audiencia en esta nueva realidad pandémica. Este artículo busca evidenciar y propone reflexionar sobre el probable uso de la narrativa transmedia en el periodismo televisivo, a través del análisis de reportajes del programa Fantástico, de la Rede Globo de televisão, en el primer mes de la cobertura de Covid-19 en Brasil, entre el 15/03/2020 y el 05/04/2020. También se pretende disociar el uso de esta narrativa en el periodismo y la ficción para ampliar el reconocimiento de su aplicación en el teleperiodismo; además de señalar los cambios en la actuación de reporteros y entrevistados en la construcción narrativa en tiempos de pandemia. O uso da narrativa transmedia ou storytelling (como é grafado em inglês) no jornalismo, além de corresponder a um modelo de negócio impulsionado pela convergência nos media contemporâneos, pode ser considerado um caminho para imersão do público no universo informativo. Em tempos de pandemia pela Covid-19, a cobertura telejornalística no Brasil reforça que o jornalismo não deve ser apenas declaratório, sendo insuficiente apenas investir em estatísticas e reportar estudos científicos ao redor do mundo.

Pretende-se, ainda, dissociar o uso desta narrativa no jornalismo e na ficção a fim de alargar o reconhecimento de sua aplicação no telejornalismo; além de apontar as mudanças na atuação dos repórteres e entrevistados na construção narrativa em tempos de pandemia. The use of transmedia storytelling narrative in journalism, in addition to corresponding to a business model driven by the convergence in contemporary media, can be considered the way for the public to immerse themselves in the informative universe. In times of Covid-19 pandemic, TV news coverage in Brazil reinforces that journalism should not be just declaratory, being insufficient to invest only in statistics and report scientific studies around the world. Thus, the transmedia storytelling narrative emerges as a proposal capable of enabling the public to immerse themselves in this new pandemic reality. This article seeks to reflect on the use of transmedia narrative in television journalism, through the analysis of the reports of the program Fantástico, from Rede Globo, in the first month of coverage of Covid-19 in Brazil, between 03/15/2020 to 04/05/2020. It is also intended to dissociate the use of this narrative in journalism and fiction in order to broaden the recognition of its application in television news, in addition to pointing out the changes in the performance of reporters and interviewees in narrative construction in times of pandemic.

    Introduction: One year ago, Portugal entered its first lockdown because of the coronavirus disease-2019 (COVID-19) pandemic. The impact of this on delays in cancer diagnosis and treatment is a major concern, which may negatively affect the outcomes of these patients. Materials and methods: This retrospective, single-center analysis compared the clinical and pathological characteristics of breast cancer (BC) patients referred to a medical oncology first appointment between March 2020 and 2021, with the same period in the previous year. Results: Strikingly, there was a 40% reduction in the number of BC patients during lockdown. However, there was a statistically significant increase in the proportion of metastatic BC patients admitted for the first time for systemic therapy (13.6% vs. 28.9%, p = 0.003). Additionally, a statistically significant increase in the number of patients with bilateral early BC at diagnosis after March 2020 was found (7.2% vs. 1.9%, p = 0.043). Conclusion: These findings support international recommendations for an accelerated restoration of BC screening, to reduce incidence of advanced breast cancer at diagnosis and mitigate the expected impact of the COVID-19 pandemic on patients with cancer. Further work is needed to examine in detail the impact of measures to manage the COVID-19 pandemic on breast cancer outcomes. info:eu-repo/semantics/publishedVersion

    The COVID-19 crisis has revived an old heated debate on whether significant increases in the money supply - such as the ones seen after the pandemic outbreak - ultimately lead to higher inflation. Some observers have alluded to the quantity theory of money for that purpose, though in our view, this has sometimes been in a misleading way. Against this background, this paper seeks to clarify several aspects of the quantity theory of money and the so-called "monetarist" approach to it, which are useful to apply it fairly in the current world. First, we review and discuss the meaning of the velocity term in the quantity equation. We argue that it has no relevance as a behavioural concept: there is no such thing as a "desired velocity". Rather, income velocity should be seen as a variable deriving from a larger system of parameters and variables related to money demand, as the monetarista approach clearly puts it, with no intrinsic relevance. Secondly, we clarify the practical relevance that the quantity theory approach can bear in the twenty-first century. We argue that although the quantity theory is unsuitable to explain conventional monetary policies, the mechanism on which it builds bears relevance in analysing some recent unconventional monetary policies. Thirdly, we review the channels and assumptions underlying the asserted quantity theory link between money growth and inflation. In light of our analysis, we conclude that the high money growth rates seen since the pandemic outbreak are not likely to translate into higher inflation rates.

    Objective: To analyze the relationships between sociodemographic variables, intolerance to uncertainty (INT), social support, and psychological distress (i.e., indicators of Common Mental Disorders (CMDs) and perceived stress (PS)) in Brazilian men during the COVID-19 pandemic. Methods: A cross-sectional study with national coverage, of the web survey type, and conducted with 1006 Brazilian men during the period of social circulation restriction imposed by the health authorities in Brazil for suppression of the coronavirus and control of the pandemic. Structural equation modeling analysis was performed. Results: Statistically significant direct effects of race/skin color (λ = 0.268; p-value < 0.001), socioeconomic status (SES) (λ = 0.306; p-value < 0.001), household composition (λ = 0.281; p-value < 0.001), PS (λ = 0.513; p-value < 0.001), and INT (λ = 0.421; p-value < 0.001) were evidenced in the occurrence of CMDs. Black-skinned men with higher SES, living alone, and with higher PS and INT levels presented higher prevalence values of CMDs. Conclusions: High levels of PS and INT were the factors that presented the strongest associations with the occurrence of CMDs among the men. It is necessary to implement actions to reduce the stress-generating sources as well as to promote an increase in resilience and the development of intrinsic reinforcements to deal with uncertain threats.

    Equitable and efficient distribution of COVID-19 vaccines continues to be a key issue in global health, and a targeted approach is needed to meet the World Health Organization’s world vaccination targets. Although some low-and middle-income countries (LMICs) are developing their own vaccines to address the distribution problem, legal and technical challenges have had a negative impact on productivity. This article explores relevant international legal instruments that can enable faster research and development of COVID-19 vaccines in LMICs, focusing on the role of biosafety standards, biological materials transfer, and key knowledge sharing. Our analysis has established that the potential of existing global health legal instruments has yet to be realized in order to close the productivity gap in LMICs and strengthen their vaccine manufacturing capacity. Additionally, mutual recognition of vaccine efficacy has become a new challenge for achieving global vaccination targets. We argue that the World Health Organization should continue its leading position by developing a more practical and targeted framework to help LMICs overcome challenges arising from technology transfer, knowledge sharing, and politics. © 2021 by the authors.

    The COVID-19 pandemic has had significant psychological impact on vulnerable groups, particularly students. The present study aims to investigate the mental and psychological impact of the COVID-19 pandemic and associated factors in a sample of Portuguese higher education students. An online cross-sectional study was conducted among 1522 higher education students selected by convenience sampling. The survey assessed mental health symptoms as well as sociodemographic variables, health-related perceptions, and psychological factors. Results were fitted to binary and multivariable logistic regression models. The overall prevalences of stress, anxiety, and depression were 35.7%, 36.2%, and 28.5%, respectively. Poor mental health outcomes were related with being female, having no children, living with someone with chronic disease, facing hopelessness, and lacking resilient coping. Future studies focusing on better ways to promote mental health and wellbeing among students are warranted. It is necessary to gather more evidence on the postpandemic mental health using robust study designs and standardized assessment tools. info:eu-repo/semantics/publishedVersion
