ABSTRACT

This article assumes that international tourism is facing a deep crisis as a result of the COVID-19 pandemic that brought about the paralysis of the sector, resulting in trillions of losses. However, its effects occur unevenly in space-time, which requires localized studies to decipher the specificities of its impacts on tourism in different places. Therefore, this study aims to analyze the implications on tourism, specifically, on tourism services in the city of Aracaju/SE, from the restrictive measures instituted with the pandemic. The methodological procedures adopted in this exploratory research were the bibliographic survey, the documental research, as well as interviews with public agents and application of forms with city residents, with a quantitative-qualitative analysis approach. The results point to new challenges for the destination with regard to the resumption and attraction of tourist flows. In this sense, it is urgent to prepare creative proposals and protocols adjusted in the world scenario for the reactivation of the sector's activities.

ABSTRACT

Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) is used worldwide to test and trace the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). "Extraction-less" or "direct" real time-reverse transcription polymerase chain reaction (RT-PCR) is an open-access qualitative method for SARS-CoV-2 detection from nasopharyngeal or oral pharyngeal samples with the potential to generate actionable data more quickly, at a lower cost, and with fewer experimental resources than full RT-qPCR. This study engaged 10 global testing sites, including laboratories currently experiencing testing limitations due to reagent or equipment shortages, in an international interlaboratory ring trial. Participating laboratories were provided a common protocol, common reagents, aliquots of identical pooled clinical samples, and purified nucleic acids and used their existing in-house equipment. We observed 100% concordance across laboratories in the correct identification of all positive and negative samples, with highly similar cycle threshold values. The test also performed well when applied to locally collected patient nasopharyngeal samples, provided the viral transport media did not contain charcoal or guanidine, both of which appeared to potently inhibit the RT-PCR reaction. Our results suggest that open-access, direct RT-PCR assays are a feasible option for more efficient COVID-19 coronavirus disease testing as demanded by the continuing pandemic.

ABSTRACT

Due to the global COVID-19 pandemic, the government of Spain declared the State of Alarm in March 2020. One of its consequences has been the increase in remote working and online teaching-learning processes. Taking homes as unit of analysis, the data given by the Survey on Equipment and Use of Information and Communication Technologies in Households conducted by the Spanish National Institute of Statistics is analysed. Two different analyses were undertaken: A descriptive analysis on the variable possession of a computer and internet broadband (constructed from those offered by the aforementioned survey) and a logistic regression analysis on sociodemographic factors that explain the availability of ICT. The results indicate that the household model is the principal variable to explain the digital gap more accurately than other factors such as economic aspects or educational levels of those responsible for the household. © 2022, Fundacion Sistema.

ABSTRACT

The crisis can affect an organization for many reasons, including changes that occur in the market, technology, competition or even a pandemic currently experienced. With this, it is necessary to find solutions so that it is possible to work around the situation and continue operating in the market. This article aims to analyze what are the digital marketing strategies adopted by organizations in different crisis situations, including the Covid-19 pandemic. For this purpose, an integrative review of articles published in the Web of Science, Scopus, SPELL and SciELO databases was carried out. The results show that several strategies in the digital environment are capable of collaborating with the challenges that organizations face with globalization, such as investing in their websites, acting on their social media with content and campaigns, applications, virtual assistants, advertising and others. A research framework was created with the aim of synthesizing the findings of this integrative review. Organizations from different sectors can mirror these strategies to deal with the crisis they face or even join them so that they are not hit by unexpected adversities, resulting in loss of space or even their withdrawal from the market.

ABSTRACT

OBJECTIVE: The pandemic disease by SARS-CoV-2 infection does not have an effective treatment. To prevent the disease, scientists developed vaccines that the clinicians use as an emergency licensed vaccine. The objective of this study was to determine the side effects in personnel vaccinated at the Military Central Hospital of Mexico with the BNT162b2 vaccine. PATIENTS AND METHODS: This study included the subjects who had received both doses of the BNT162b2 vaccine between December 2020 and February 2021. We asked about the side effects after the first and the second vaccine doses. One group had no history of COVID-19, and the second had a history of COVID-19. ANTI-SARS-CoV-2 antibodies were measured by the immunodetection technique in the second group only. RESULTS: We included 946 participants, 62% were women, and 80% were without comorbidities; 680 were included in the first group, and only 266 were in the second group. After the first dose, 77% of the first group and 86% of the second group presented some side effects. After the second dose, 84% of the first group and 89% of the second group showed some side effects. The main side effect was mild pain. All participants (126) were IgG positive, and only 26.9% were IgM positive at 17.5 days (12.8 days, 20.3 days) after the second dose. CONCLUSIONS: There is a positive correlation between side effects after the first dose in patients with a history of previous SARS-CoV-2 infection compared to those who did not. Nevertheless, this correlation is not present after the second dose. The low percentage of IgM could be related to the time interval between vaccination and sample measure.

ABSTRACT

Introduction: To optimize hospital management of COVID-19 patients it is important to have parameters that allow us to identify patient with an increased risk of death. Although hypoalbuminemia has been related with severity in COVID-19, there is no agreement of the albumin cutoff points with a potential clinical use. Additionally, a measure of strength of the association between albumin levels and mortality has not been reported. Therefore, the aim of this study is to evaluate if Child Pug albumin categories are associated with mortality and obtain the strength of the association. Methods: Patients admitted to hospitalization with a positive SARS CoV 2 PCR from 4 April to 24 June 2020 were analyzed. Three groups were formed based on Child-Pugh albumin categories. Death frequency were compared between groups and statistical significance of the difference were assessed using a Xi2 test, strength of association between albumin levels and death was evaluated with a Kendall´s Tau B test. Results: A total of 348 patients were studied, age was 54.4 ± 14.7 years, 250 (71.8%) were male and 182 patients died (52%). Association of Albumin level and Death is presented Table 1, Kendall Tau B shows that knowing albumin level improves in 32% the prediction of death and since it has a negative coefficient at a lower level of albumin, risk of death increase. Conclusions: Kendall´s Tau-B shows a strong association between Child-Pug albumin categories and death, so is possible it´s use in clinical decisions as a marker of severity.

ABSTRACT

The objective of the research was to describe how an alert about the seriousness of COVID-19 had resonance, performing controversies in Brazil. We elected the alert of a specialist, the researcher Atila Iamarino. Data collection was carried out by means of documentary research, based on data made available on the internet, on YouTube videos, reports and texts in magazines, as indicated by Venturini (2012), for cartography with digital data. We show how Atila Iamarino's public alert acquired resonance, based on her argument that COVID-19 was a risk, requiring a measure of social isolation. This allowed the alert to be understood and taken seriously, when its arguments generally rose.

ABSTRACT

Data collection was carried out by means of documentary research, based on data made available on the internet, on YouTube videos, reports and texts in magazines, as indicated by Venturini (2012), for cartography with digital data. Tendo como epicentro a cidade de Wuhan, na China, o que aparentemente se tratava de casos pontuais havia se transformado em uma séria epidemia no territorio chines, tornando necessário o fechamento das atividades do mercado de frutos do mar de Wuhan, acreditando-se que os animais ali contidos poderiam ser a origem do virus (Kucharski et al., 2020;Williams, 2020). Em 30 de janeiro, cerca de um mes após a China identificar o virus e tornar pública a sua situaçao, a OMS declarou que o surto da doença causada pelo novo coronavirus (COVID-19, do ingles Coronavirus Disease 2019) constituia uma Emergencia de Saúde Pública de Importancia Internacional (OMS, 2020;Kucharski et al., 2020). Por fim, na seçao 5, as consideraçöes finais, limitaçöes e futuras pesquisas. 2REFERENCIAL TEÓRICO 2.1A Construçao de Problemas Públicos O debate construtivista sobre problemas públicos, presente na década de 1970 e 1980, foi ressignificado nas pesquisas sobre arenas públicas e construçao de problemas públicos, especialmente, em Cefai' (2009;2017a;2017b), que procurou inspiraçöes no filósofo John Dewey.
