Polymers with antiviral properties: A brief review.
2021
Viruses that are pathogenic to humans and livestock pose a serious epidemiological threat and challenge the world's population. The SARS-CoV-2/COVID-19 pandemic has made the world aware of the scale of the threat. The surfaces of various materials can be a source of viruses that remain temporarily contagious in the environment. Few polymers have antiviral effects that reduce infectivity or the presence of a virus in the human environment. Some of the effects are due to certain physical properties, e.g., high hydrophobicity. Other materials owe their antiviral activity to a modified physicochemical structure favoring the action on specific virus receptors or on their biochemistry. Current re…
Possible transmission flow of SARS-CoV-2 based on ACE2 features
2020
AbstractAngiotensin-converting enzyme 2 (ACE2) is the cellular receptor for the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) that is engendering the severe coronavirus disease 2019 (COVID-19) pandemic. The spike (S) protein receptor-binding domain (RBD) of SARS-CoV-2 binds to the three sub-domains viz. amino acids (aa) 22-42, aa 79-84, and aa 330-393 of ACE2 on human cells to initiate entry. It was reported earlier that the receptor utilization capacity of ACE2 proteins from different species, such as cats, chimpanzees, dogs, and cattle, are different. A comprehensive analysis of ACE2 receptors of nineteen species was carried out in this study, and the findings propose a pos…

Demographic inequalities as determinants and consequences of the COVID-19 pandemic in Latvia
2021
Since early March 2020 Latvia is fighting the COVID-19 pandemic. Lessons learned from this crisis will be instrumental in shaping future public health policy. Any policy response to the pandemic must be tailored to the particular risks within population in order to avoid the unnecessary social and economic damage on a national and international scale. Available literature on the topic highlights region-specific demographic factors associated with elevated population vulnerability to the effects of the COVID-19 pandemic. This study aims to ascertain the role of a pre-existing demographic inequalities in Latvia in the onset and progression of COVID-19 pandemic and lay groundwork for projectin…

Face mask use in the Community for Reducing the Spread of COVID-19: a systematic review
2021
ABSTRACTBackgroundEvidence is needed on the effectiveness of wearing face masks in the community to prevent SARS-CoV-2 transmission.MethodsSystematic review and meta-analysis to investigate the efficacy and effectiveness of face mask use in a community setting and to predict the effectiveness of wearing a mask. We searched MEDLINE, EMBASE, SCISEARCH, The Cochrane Library and pre-prints from inception to 22 April 2020 without restriction by language. We rated the certainty of evidence according to Cochrane and GRADE approach.FindingsOur search identified 35 studies, including 3 randomised controlled trials (RCTs) (4017 patients), 10 comparative studies (18984 patients), 13 predictive models,…

The digital divide in the world of education at the time of Covid-19
2021
Education in the digital age uses new intelligent technologies as enabling and daily tools at the service of learning. Education has always been a challenge and today it is even more so since, given the many difficulties of the moment, to support the school in the time of Covid-19 it is necessary to implement rapid and timely changes that require, in addition to high investments, also new ways of sharing knowledge. Only by acting in this direction is it possible to make a virtue of necessity and transform the many critical issues, due to the pandemic causes, into strategic opportunities. The spread of Covid-19 has forced 80% of students around the world to not go to school and stay at home,…
Comparing SARS-CoV-2 case rates between pupils, teachers and the general population: results from Germany
2021
Given the inconsistent state of research regarding the role of pupils and teachers during the SARS-CoV-2 pandemic in Germany, statewide and nationwide data of infection case rates were analyzed to contribute to the discourse. Infection data from official sources ranging from mid to late 2020 were collected, prepared and analyzed to answer the question if pupils, teachers and general population differ in infection case rates or not. Statewide and nationwide data showed that pupils and teachers infection case rates exceeded those of the general population. However, present data do not necessarily indicate that SARS-CoV-2 cases of pupils and teachers infections took place at schools. Actually,…
El desarrollo rural a partir de la gobernanza territorial en tiempos del coronavirus (Ocón, La Rioja, España) / / / \ \ \ Rural development from the …
2020
Resumen: Con una tendencia demográfica descendente y una pérdida de servicios y de ofertas de consumo durante la segunda mitad del s XX, los pueblos de Ocón (La Rioja) presentaban las mismas características que la mayor parte de zonas rurales del interior peninsular. Durante las dos últimas décadas, Ocón ha conseguido revertir esta situación, con un desarrollo local muy activo y dinámico, como se ha dejado ver en la diversificación de su economía, en la revitalización de sus núcleos de población a través de la ejecución de multitud de proyectos e infraestructuras y en una mayor oferta de servicios, que poco a poco van cubriendo las demandas de la población. Demográficamente, presenta un ele…
