ABSTRACT

Introduction: With the confrontation of the COVID-19 pandemic, there was a drastic change in the daily life routines, with reflexes on the general health and impacts on the sleep quality of many Brazilians. This fact leads to a glimpse of the potential existing in virtual actions with a wide population reach, focused on health promotion and disease prevention as an alternative to minimize damage to quality of life. Objective: To disseminate safe information in a virtual environment to the general population in a simple and illustrative way about sleep health. Methods: The university extension project has been underway since October 2020 and has the participation of 10 undergraduate students from the Speech Therapy course and two advisor professors. The first stage of the project was aimed at training and updating the team, by remote means, on issues involving sleep health;in the second stage, there was the creation of a public profile on the social network and the elaboration/confection/publication of illustrative informative materials and with simple and comprehensive language (videos, posters, comics, leaflets, technical sheets and the like);the third stage featured/relies on live virtual actions focused on health promotion and prevention through lives, seminars and open classes conducted by professionals from different health areas and sleep specialists. Results: Between October 2020 and August 2021 the digital profile published 39 posts, IGTV or Reels with informative content about sleep, in addition to more than 200 stories. More than 3000 “likes or likes” were registered in the publications, 3,507 views on IGTV, 347 comments, 381 shares (of which 150 were saved by followers or visitors), 8,280 visits to the profile and 18,524 people/accounts were reached for a virtual audience of 1,731 people/following accounts located in Sergipe, São Paulo, Pernambuco and Bahia, in addition to a small percentage of Spanish, Portuguese, Colombian and German followers. It is also important to highlight that the project awakens in the students the relevance of disseminating information based on reliable sources. Conclusion: Through the execution of the project, important and safe information can be disseminated in a virtual environment to clarify, inform and popularize science with knowledge about sleep health and the prevention of its disorders to an expressive public.

ABSTRACT

Introduction: At the end of 2019 in the city of Wuhan, China, the first cases of respiratory syndrome caused by coronavirus 2019 disease (COVID-19) were described. Obesity or malnutrition, associated with comorbidities such as hypertension and diabetes can significantly increase the risk of hospitalization and death in these patients. Goals: to evaluate the relationship between nutritional status and the presence of comorbidities with the length of hospital stay, biochemical parameters and clinical outcome of patients with COVID-19. Materials and methods: a retrospective study that is part of a multicenter project from the Federal University of Alagoas and with a collaborating center at the Federal University of Pernambuco, carried out from the collection of data from medical records of patients hospitalized with COVID-19, who were hospitalized in a hospital in Pernambuco and one in Alagoas from March to December 2020. Data were analyzed using the Statistical Package for Social Sciences (SPSS) software, version 20.0, and the significance level adopted was 5%. Results: The sample consisted of 97 patients, mostly elderly, where 66.9% of patients had hypertension and 41.2% diabetes. The group with a previous diagnosis of diabetes had a longer hospital stay when compared to the group without this comorbidity (p = 0.050). The mean BMI was 26.2 +/- 4.85 kg/m(2), where most patients were overweight (46.2%) and 8.8% were underweight. In the analysis of the association between the study variables and the clinical outcome, it was observed that age and the diagnosis of diabetes were associated with the outcome of death. Conclusion: Worse clinical prognosis, increased length of hospital stay and higher risk of mortality were observed among diabetic and older patients.

ABSTRACT

As recent studies show, tourists increasingly favour hotels and other tourism businesses that adopt more environmentally sustainable practices. A tourism depends on and significantly impacts cultural heritage and local communities’ well-being, sociocultural sustainability also plays a significant role on tourists’ decisions. Despite this trend, price is still the main determinant factor in tourists’ choices, and most sustainable practices tend to add operational costs, and consequently, make services more expensive. In this context, more than knowing which sustainable practices are valued the most by tourists, it is important to know how much they are willing to pay a premium price to visit destinations where those practices are carried out. In this context, the present study aimed to explore the dimensions of willingness to pay for sustainability in tourism destinations and the sustainability attitudes that might affect them. Additionally, as previous studies suggest young travellers attribute a greater value to sustainability, differences between age groups were also explored. To this end, data were collected through a survey questionnaire (n = 562) with Portuguese tourists. The questionnaire included 16 willingness to pay items and 22 sustainability attitude items. The results point to two main willingness to pay dimensions and four sustainability attitude factors. Moreover, a higher willingness to pay for environmental and sociocultural sustainability, as well as higher levels of pro-environmental private behaviour, was found amongst younger travellers. The findings offer useful insights for destination managers, which must consider them when planning and promoting innovative tourism products based on nature and cultural heritage. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

ABSTRACT

Objetivos: A pandemia da COVID-19, doença causada pelo coronavírus da síndrome respiratória aguda grave 2 (SARS-CoV-2), já ultrapassou 200 milhões de casos no mundo e mais de 4 milhões de óbitos. Os indivíduos podem apresentar-se assintomático, com sintomas leves ou graves associados às infecções do trato respiratório. Pacientes com COVID-19 apresentam anticorpos do tipo IgG em média duas semanas após a infecção, e persistem em níveis estáveis por alguns meses. Ainda não foi completamente elucidada a influência dos níveis desses anticorpos e o tempo de permanência em circulação, com a proteção e gravidade da doença em reinfecções. O objetivo deste trabalho foi avaliar a presença de anticorpos anti-SARS-CoV-2 IgG em pacientes assintomáticos ou com sintomas leves em um período de 3 meses. Material e métodos: Estudo prospectivo em que indivíduos adultos de ambos os sexos, participantes do projeto EpiSergipe e que apresentaram resultado positivo ao teste rápido para IgG/IgM confirmado por sorologia, foram convidados a continuar participando da pesquisa durante o período de 3 meses. Para as análises foram coletadas amostras de sangue periférico, sendo a amostra inicial descrita como D+0 e a final como D+90. A análise sorológica foi realizada por meio do kit comercial, de imunoensaio fluorescente (IchromaTM COVID-19 Ab) e os procedimentos foram realizados de acordo com as recomendações do fabricante. Resultados: Foram analisadas amostras dos 20 indivíduos, sendo 9 do sexo masculino e 11 do sexo feminino. A idade variou de 28 a 73 anos. Os sintomas mais comumente relatados foram mal-estar, febre, cefaleia e dor de garganta. Os níveis de IgG no D+0 variaram de 19,4 a 45,7, média de 34,47 (± 7,12), e no D+90 a variaram de 1,2 a 45,6, com média de 20,64 (± 12,18). Após 3 meses foi observada uma diminuição significativa (p < 0,0001) dos níveis de IgG em 85% dos indivíduos com média de 52,74%, e apenas 15% apresentaram aumento significativo (p < 0,05) com média de 27,47%. Discussão: Estudos descrevem que os níveis de IgG permanecem por apenas 3-4 meses no organismo dos indivíduos que tiveram contato prévio com o SARS-CoV-2, entretanto neste estudo inicial foi observado que a maioria dos indivíduos apresentou uma diminuição significativa e gradual de anticorpos IgG anti- SARS-CoV-2 circulantes, antes mesmo de completos os 3 meses após a exposição ao vírus. Conclusão: A partir destes resultados preliminares é possível compreender que os indivíduos, sejam eles assintomáticos ou sintomáticos leves, apresentaram soroconversão, produzindo IgG e estes anticorpos permaneceram em circulação por um período mínimo de 3 meses. Este estudo apresenta dados mais extensivos, ainda em análises, que futuramente corroborarão com a compreensão desta manutenção de anticorpos, e ainda assim, serão necessários mais estudos com o mesmo objetivo.

ABSTRACT

Objetivo: Descrever os dados epidemiológicos da COVID-19 em pacientes onco-hematológicos em dois centros de tratamento do Espírito Santo. Métodos: Estudo retrospectivo utilizando dados de prontuário dos aspectos epidemiológicos da COVID-19 em pacientes onco-hematológico atendidos no Hospital Santa Casa de Misericórdia de Vitória (HSCMV) e Hospital Universitário Cassiano Antônio Moraes (HUCAM), no período de fevereiro/2020 a fevereiro/2021. Resultados: Avaliado, no período de 12 meses, 406 pacientes com neoplasias hematológicas, sendo 195 HSCMV e 211 HUCAM. Identificados 36 pacientes com COVID 19 sendo 44% (16) HUCAM e 56% (20) HSCMV. Quanto ao sexo: 33% (12) feminino e 67% (24) sexo masculino. A média de idade foi 56 anos, menor idade 23 e maior 82. Em relação ao diagnóstico hematológico: 22% (8) leucemia aguda, 14% (5) mieloma múltiplo, 8% (3) SMD, 14% (5) doença mieloproliferativa crônica, 14% (5) linfoma de baixo grau e 28% (10) de alto grau. As comorbidades de risco para COVID estavam presentes em 47% (17), com predomínio da Hipertensão arterial 36% (13). Considerando a linha temporal os meses de maior incidência foram: maio (8), junho (5) e julho (6), agosto (5). A maioria dos diagnósticos foi por RT-PCR,porém16% (6) por sorologia. Em relação à provável fonte de contaminação 39% (14) estavam internados por outros motivos quando desenvolveram sintomas de COVID, 14% (5) relatavam contato com paciente positivo, os outros 47% (17) adquiriram por provável infecção comunitária. Boa parte dos pacientes estavam em quimioterapia 39% (14) ao diagnóstico de COVID. Quadros classificados como COVID grave pelos critérios do MS foram observados em 53% (19), mas 55% (20) necessitou de UTI, destes a maioria (15) precisou de ventilação mecânica. 92% (33) tinham anemia, no entanto, neutropenia foi observada em apenas 16% (6). A taxa de letalidade por COVID-19 e suas complicações foi 39%. Discussão: Informações sobre a incidência de COVID-19 entre pacientes com câncer são variáveis. Sugere-se maior incidência em pacientes com câncer em relação à população geral, mesmo quando ajustado para fatores de risco, como idade avançada e comorbidades. O risco da COVID-19 parece ser maior para aqueles com câncer hematológico e de pulmão. Dados franceses sugerem maior necessidade de UTI em pacientes oncohematológicos (25%) quando comparados a outros tipos de neoplasia. Os dados deste estudo demostram maior gravidade quando comparados a outros centros (São Paulo e França), visto a alta taxa de necessidade de UTI e letalidade. É possível perceber a relação do aumento da incidência com os dados de infeções comunitárias regionais, no entanto ainda é relevante o número de pacientes que adquirem a COVID 19 durante a internação por outros motivos. A minoria apresentava neutropenia o que pode sugerir que outros mecanismos de imunossupressão da doença de base possuem maior impacto além da quimioterapia recente. Conclusão: Os dados corroboram que neoplasias hematológicas possuem piores desfechos comparados a dados de literatura para outros tipos de câncer e para população geral reforçando a necessidade de reavaliar as medidas de prevenção/proteção já adotadas. Estratégias diferenciadas de testagem durante internação podem propiciar diagnóstico precoce prevenindo contaminações nas enfermarias. Estudos de eficácia da vacinação nestes pacientes podem ser importantes para abordagem diferenciada de esquema vacinal permitindo melhor proteção para casos graves de COVID -19.

ABSTRACT

Introdução: Estudos apontam relação entre grupos sanguíneos e diversas condições clínicas como, por exemplo, eventos trombóticos, doença de von Willebrande doenças infecciosas como SARS-CoV-1, H. pylori entre outros. Associação entre maior susceptibilidade à COVID-19 e pior evolução em indivíduos do grupo sanguíneo A vem sendo estudada por diversos grupos. Objetivo: Neste estudo, analisamos a correlação entre os grupos sanguíneos ABO e resultado do teste para o vírus SARS-CoV-2 por RT-PCR em um laboratório de análises clínicas com grande fluxo de amostras representativas das cinco regiões do Brasil. Material e métodos: Os dados foram obtidos do banco de dados do laboratório referente a 20 anos de registro, analisados de forma anonimizada e de acordo com as regras que regem a lei geral de proteção de dados (LGPD). Os registros possuem um identificador numérico único que leva em conta CPF e data de nascimento e todas as análises foram feitas considerando-se esta identificação. Foram obtidas as tipagem sanguínea ABO/Rh e os resultados de RT-PCR para SARS-CoV-2. Para este último, os indivíduos foram classificados “covid-positivo”quando ao menos um exame resultou positivo. Os demais foram considerados “covid-negativo”. As análises foram realizadas no banco de dados obtido do cruzamento do banco de indivíduos únicos com tipagem sanguínea e ao menos um teste para COVID-19. Análise estatística foi realizada do teste chi-quadrado de Pearson e V-quadrado de Cramér. Resultados e discussão: Foram identificados 66.181 indivíduos que realizaram tipagem sanguínea e ao menos um teste para SARS-CoV-2. A distribuição global dos grupos ABO é a que segue: grupo O 44%, grupo A 41%, grupo B 11% e grupo AB 4%, compatível com a distribuição dos grupos no Brasil (O 45%, A 42%, B 10% e AB 3%).Do total de indivíduos estudado, 21% (13.617) apresentou ao menos um resultado positivo para SARS-CoV-2, distribuídos da seguinte forma por grupo sanguíneo: tipo O 42%, A 42%, B 12% e AB 4%. A distribuição dos grupos sanguíneos entre os indivíduos negativos para SARS-CoV-2 foi: tipo O 44%, A 41%, B 11% e AB 4%. As análises consideraram grupo ABO e Rh. Foi realizado um teste chi-quadrado de independência de variáveis e verificou-se associação positiva entre o tipo sanguíneo e a infecção por COVID-19 (χ2 = 27,273, df = 7, p = 0,0002975).O teste pós-hoc de comparação entre status de COVID-19 e tipo sanguíneo sugere associação entre o tipo B- e infecção por COVID-19 (p = 0.0407700).Entretanto, este dado não foi confirmado por análise adicional pelo teste V de Cramér, sugerindo que o efeito observado está provavelmente associado ao grande número de amostras do que uma associação real entre as variáveis.Sabe-se que a testagem para COVID-19 pode resultar em falso negativo quando realizada fora da janela de maior sensibilidade para detecção do vírus. Deve-se considerar que, na presente análise, a informação sobre início dos sintomas e data de realização do teste não está disponível. Entretanto, o grande número de casos analisados diminui o impacto da ausência desta informação. Outro ponto importante a ser considerado é que não foram avaliados parâmetros de evolução clínica dos pacientes, sendo os dados restritos à presença ou não de diagnóstico positivo para COVID-19. Conclusão: Não foi demonstrada associação entre o tipo sanguíneo e a suscetibilidade a infecções por COVID-19 no grupo analisado.

ABSTRACT

Objetivos: A COVID-19, oriunda do novo coronavírus (SARS-CoV-2) se espalhou como uma pandemia, causando mais de 4 milhão de mortes globalmente, tornando-se uma emergência de saúde pública. O número de casos de pacientes recuperados é crescente, o que pode ser crucial sobre o curso da doença. Na forma grave da doença é possível observar linfopenia e leucopenia. Estes achados podem ser auxiliares como indicadores clínicos para avaliação e progressão da doença. Desta forma, este trabalho teve como objetivo descrever o perfil leucocitário dos indivíduos positivos na sorologia para o SARS-CoV-2. Material e métodos: Trata-se de um estudo prospectivo em que indivíduos adultos de ambos os sexos, participantes do projeto EpiSergipe e que apresentaram resultado positivo ao teste rápido para IgG/IgM confirmado por sorologia. Foram coletadas amostras de sangue periférico para realização do hemograma e análise sorológica utilizando o kit comercial de imunoensaio fluorescente (IchromaTM COVID-19 Ab) em que os procedimentos foram realizados de acordo com as recomendações do fabricante. Resultados: Foram analisadas amostras de 847 pacientes com sorologia positiva para o SARS-CoV-2, assintomáticos ou com sintomas leves, sendo 275 do sexo masculino (32,47%) e 572 do sexo feminino (67,53%). Do total de hemogramas analisados, 9,33% apresentaram leucocitose e 2,01% leucopenia (média leucócitos totais = 7.370/mm3 /±2,10). A linfocitose foi observada em 23,61% dos indivíduos e a linfopenia foi observada em apenas 1,18% (média linfócitos = 2.550/mm3/±772). A neutrofilia foi observada em 5,90% dos participantes e a neutropenia em 5,31% (média neutrófilos = 4.280/mm3/±1,67). A maioria dos hemogramas analisados (67,41%) apresentaram todos os parâmetros normais. Discussão: A linfocitose, de acordo com estudos, pode auxiliar na previsão e acompanhamento da progressão da COVID-19, neste estudo foi observada em 23,61% dos hemogramas analisados, enfatizando que os participantes do presente estudo eram assintomáticos e sintomáticos leves, o que pode justificar o porquê grande parte dos pacientes apresentaram parâmetros dentro da normalidade. Além disso um estudo publicado em 2021, comparou os achados hematológicos de óbitos por COVID-19 com os de sobreviventes, nos indivíduos que morreram havia maior contagem de neutrófilos e leucócitos, e uma diminuição nos linfócitos, quando comparados aos sobreviventes. Neste estudo, não houveram óbitos, as taxas encontradas de leucocitose e neutrofilia foram de 9,33% e 5,90% respectivamente, e a linfopenia 1,18%. Conclusão: A partir dos resultados prévios encontrados, observa-se alterações no perfil leucocitário em indivíduos com COVID-19, condizentes com os descritos recentemente na literatura.

ABSTRACT

Objetivos: Comparar níveis de citocinas e quimiocinas entre indivíduos infectados com SARS-CoV-2 com COVID-19 grave ou com a forma assintomática da infecção, a fim de avaliar quais destes marcadores biológicos de resposta inflamatória são indicadores de gravidade da infecção viral. Métodos: Foram analisados dados clínicos de 48 pacientes com COVID-19 hospitalizados no Hospital Eduardo de Menezes (FHEMIG, MG) no período de 07 de julho a 21 de novembro de 2020, que necessitaram ou não de assistência em terapia intensiva (grupos UTI e sem UTI, respectivamente). Foi feita a quantificação dos níveis de citocinas (IL-2, IL-4, IL-6, IL-10, TNF, IFN-, IL-17A) e quimiocinas (CCL2, CCL5, CXCL8, CXCL9 e CXCL10) do plasma de 14 pacientes UTI e 17 pacientes sem UTI que tinham COVID-19 grave no momento da coleta da amostra, além de 24 doadores de sangue da Fundação Hemominas com infecção ativa pelo SARS-CoV-2 (RT-PCR positiva) que eram assintomáticos no momento da coleta da amostra. Resultados: A análise clínica dos pacientes UTI (n = 19) em comparação àqueles que não usaram UTI (n = 29) não mostrou diferença estatística quanto à frequência de comorbidades e de sinais e sintomas para COVID-19 na admissão hospitalar. A comorbidade mais comum foi hipertensão (62,5%), seguida por diabetes (37,5%) e obesidade (22,9%). Tosse, dispneia, febre, fatiga e mialgia foram os sinais e sintomas mais prevalentes de COVID-19 em ambos os grupos. Entretanto, os pacientes UTI desenvolveram doença grave ou crítica que requereu um período de hospitalização em média duas vezes mais longo que o grupo sem UTI (p < 0,001). O conjunto dos pacientes com COVID-19 mostrou níveis significativamente mais altos de IL6, IL10 e CCL5 que os doadores assintomáticos. Na comparação dos grupos dos pacientes houve diferença significativa apenas para IFN, com níveis mais elevados nos pacientes UTI. Discussão: Apesar do grupo de pacientes UTI apresentarem quadro de COVID-19 mais grave que os pacientes sem UTI, a frequência de sinais e sintomas da doença e de comorbidades não foi significativamente diferente entre os grupos. A evolução da COVID-19 de assintomática para grave e crítica tem sido associada com intensa resposta inflamatória, o que está de acordo com maiores níveis de IL6, IL10 e CCL5 observados nos pacientes em comparação aos doadores assintomáticos. Nível de IFN pode ser especial indicador de gravidade da doença. Conclusão: Marcadores biológicos, como citocinas e quimiocinas, podem ser melhores preditores de evolução da COVID-19 que sinais clínicos e sintomas. Suporte financeiro: Fundação Hemominas e SES/MG.

ABSTRACT

Background. Brazillian authorities reported a total of 16.3 million cases and 454. 000 deaths during COVID-19 pandemic in Brazil by may 2021. It became necessary to educate healthcare professionals on diagnosis and treatment of the syndrome. Game based learning surfaced as an effective alternative, since it promotes critical thinking and problem solving skills. A team of Brazilian and Peruvian students, physicians, designers and programmers gathered to create a decision based computer game that simulates a hospital scenario and allows medical students to analise, make decisions and receive feedback. This work describes the creative process and showcase the initial version of the software. Methods. Professors and students of Medicine, Information Technology (IT), Design and Architecture from Brazil and Peru assembled a team in order to develop the computer game. Clinical cases were created by the medical students and professors, comprising medical procedures for the treatment and management of COVID 19, and a video game script was developed exploring gamification principles of challenge, objectivity, persistence, failure, reward and feedback. Algorithms (image 1) were created, under supervision of professors of Medicine, to define possible courses of action and outcomes (e.g. gain or loss of points, improvement or worsening of the patient). Students of Design created artistic elements, and IT students programmed with a game engine software. This fluxogram, written in portuguese, describes in detail all the possible courses of actions that can be exercised by the player. It is created by a team of Professors of Medicine and medical students, in accordance with evidence-based guidelines. Primarily, this document guides the programmers and designers throughout the development phase of the game. Results. Initially, an expandable minimum viable product was obtained. The game, visualized on image 2, consists in a non-playable character and a playable character (i.e. doctor), with a scenario and a dialogue script simulating a clinical examination of a COVID 19 patient. The player can interact with certain elements within the game, e.g. the computer and other characters, to retrieve test results or start dialogues with relevant information. Hospital scenario and dialogue window between doctor (player in black) and patient (non playable character) are displayer in the game engine software (Unity 2D). On the bottom half of the screen, the dialogue box allows the player to collect the patient's medical history. The player can interact with certain elements to obtain relevant information to make decision and progress in the game. Conclusion. The game allows medical students to practice diagnosis and treatment of COVID 19. Future versions will include assessment reports of player's actions, and a new score system will be implemented. New diseases will be incorporated in the gameplay to match the variety of scenarios offered by real hospitals and patients. Artificial intelligence will be employed to optimize gameplay, feedback and learning.

ABSTRACT

The 2019/2020 school year will always be remembered for the impact of the COVID-19 pandemic. For the first time in recent history, countries closed schools and forced instructors and students to quickly adjust to online classes. This sudden and forced shift to a method of teaching that was completely different from what we were used to presented several challenges and opportunities on a pedagogical level. In this paper we describe our experience as instructors in a course on microprocessor programming in the Master’s Degree in Computer Science and Computing Engineering at the Faculty of Engineering of the University of Porto. Our approach included changes to the assessment plan, which became more distributed, and improvements in communication between students and instructors through the use of Slack. We found that the changes introduced were not only very well received by students, but also resulted in the best exam attendance and average final grade in the last 10 years of the course’s history. © 2021 IEEE.

ABSTRACT

The 2020/2021 academic year started full of uncertainties for new students of higher education in Portugal. The restrictions imposed by the COVID-19 pandemic, the fears of a new lockdown, all coupled with the well-known challenges that a university student faces in his first year, made this year a particularly challenging year in terms of the students’ integration. In this paper, we present how the mentoring programme of the Integrated Master in Informatics and Computing Engineering at the Faculty of Engineering of the University of Porto was adapted to help the integration of first-year students in the university environment under the pandemic. © 2021 IEEE.

ABSTRACT

Background: There are recognized complications in patients infected by COVID-19 and thrombotic processes are closely related to infection. Objective: To describe the factors associated with increased risk in thrombotic events in COVID-19. Material and methods: Case-control study to identify factors associated with thrombotic processes in patients with COVID-19. Descriptive, comparative and inferential statistics were used, as well as logistic regression.The value of p <0.05 was determined as statistically significant and the statistical program IBM SPSS V.25 was used. Results: 15 cases of acute thrombosis were assesed, 17.5% were arterial and 8.8% were venous, 66.7% (n = 10) were men.Therapeutic anticoagulation and surgical procedures were neccesary. There was an association as a risk factor the fact of presenting some comorbidity (p = 0.005), and prolonged aPTT (p = 0.10), as well as abnormalities in the D-dimer. Conclusions: Infected patients suffers from hypercoagulability and confers a high risk of thrombosis. Significant elevation of D-dimer may be one of the markers of inflammation. The condition of presenting COVID-19 is not a contraindication for any revascularization procedure, which encourages us to improve our diagnostic and therapeutic behavior in patients with COVID-19 infection. © 2021 Sociedad Mexicana de Angiología y Cirugía Vascular y Endovascular, A.C.

ABSTRACT

Chest X-ray (CXR) images help specialists worldwide to diagnose lung diseases, such as tuberculosis and COVID-19. A primary step in an image-based diagnostic tool is to segment the region of interest. That facilitates the disease classification problem by reducing the amount of information to be processed. However, due to the noisy nature of CXRs, identifying the lung region can be a challenging task. This paper addresses the lung segmentation problem using a less costable computational process based on image analysis and mathematical morphology techniques. The proposed method achieved a specificity of 92.92%, a Jaccard index of 77.77%, and a Dice index of 87.37% on average. All images that comprehend the dataset used and their respective ground truths are available for download at https://github.com/mnzluiza/Lung-Segmentation. © 2021 IEEE.

ABSTRACT

This paper presents some current results of the research, which proposes a virtual recreation of Reynaldo Dierberger original project for the Seropédica campus of UFRRJ, located in Rio de Janeiro State, Brazil. The gardens, as well as the original architectural ensemble, in neocolonial style, have been legally protected in 2001. The group of researchers faced a triple challenge to make the virtual recreation. The first one concerns the identification of what was designed and not built, based on original hand-made drawings filed in the Document Conservation Laboratory of UFRRJ (LabDOC) and other university departments. The second challenge concerns the interpretation of the elements from English Garden design principles that emerged in the 19th century and were developed in Brazil by European landscapers such as Glaziou (1828-1906). The third one concerns making design drawings digital to elaborate 3d models considering a group of digital graphic tools available and also the application of Sevilla Principles (2011). It is important to mention that some of the research activities were impaired by the COVID-19 pandemic. © 2021 A. P. R. Araujo et al.

ABSTRACT

The COVID-19 pandemic has lasted for over 1 year. During the pandemic, several software development companies migrated to working from home (WFH). Several studies have recorded an initial moment of adaptation to WFH. This study investigated how BRAian software development teams dealt with WFH after 1 year of a pandemic and how this change in work was on the software development process. We applied a survey with 67 participants of software development teams and investigated aspects, as: work routine, collaboration, communication, productivity, financial assistance and software development process. We performed a quantitative and qualitative analysis of the survey results and compared them with previous studies. Our key findings are: (i) 56.71% of the participants said that it has an impact on the work routine related to work overload and exceeds the company's standard hours;(ii) 92.54% of the participants consider their team to be collaborative;(iii) 82.70% are satisfied with the communication at WFH;(iv) 86.55% has meetings once or twice a day;(v) 59.7% had an improvement in productivity in WFH and 75% are satisfied with their productivity;(vi) 79.60% receive some assistance from the company for WFH;(vii) 82.1% said that the company intends or probably intends to continue in the WFH, and (viii) 55.2% said they had changed in the software development process due to WFH. The main positive changes in the process are related to the practices of: daily meetings, agile processes, code review, pair programming and code versioning. © 2021 ACM.

ABSTRACT

Assessment is an important part of the educational process, playing a crucial role in student learning. The increase in the number of students in higher education has placed extreme pressure on assessment practices, often leading to a teacher having hundreds of assignments to correct, not only giving feedback too late, but also low quality feedback, as it is humanly impossible to correct all these assessments by giving quality feedback in such a short time. Due to the social confinement caused by the pandemic of COVID-19, there was the need to change the evaluation method initially associated with a thin exam, to a continuous evaluation method based on multiple weekly assignments. In order to deal with this situation, we developed AOCO, the first automatic correction tool for the ARMv8 AArch64 assembly language. This work presents the AOCO tool, as well as the results of the evaluation of a first use with students © 2021 IEEE.

ABSTRACT

Background: Cancer patients appear to be a vulnerable group in COVID-19 pandemic. We aimed to compare clinical characteristics and outcomes of cancer and non-cancer patients with COVID-19 admitted to an intensive care unit (ICU). Methods: We conducted a retrospective case-control study in patients with laboratory-confirmed COVID-19, with and without cancer, admitted to the ICU of “Centro Hospitalar Universitário do Porto” from 2nd March 2020 to 31st January 2021. Patients were matched according to age, gender and underlying comorbidities. Clinical, laboratory and radiological findings were obtained from medical records. COVID-19 related outcomes of both groups were compared using logistic regression. Results: 29 critical COVID-19 cancer patients (cases) and 29 critical COVID-19 non-cancer patients (controls) were enrolled. Fever, dyspnea and cough were the most common presenting symptoms in both groups. Lymphopenia and elevated lactate dehydrogenase were the most common laboratory findings in both groups and anemia was observed significantly more often in cancer patients (75.9% vs 44.8%;p=0.031). Ground glass opacities were more frequently seen in controls (100% vs 67%;p=0.018). Univariate regression revealed that invasive mechanical ventilation (IMV) need on ICU admission was significantly higher among cancer patients [48% vs 7%;odds ratio (OR)= 12.600, 95% confidence interval (CI) 2.517-63.063, p=0.002] but there was no significant impact either on global need of IMV during all-length ICU stay (76% vs 55%;OR= 2.554, 95% CI 0.831-7.842, p=0.102) or on mortality rates (59% vs 38%;OR= 2.318, 95% CI 0.809-6.644, p=0.118). A multivariate model showed an increase in the adjusted risk of IMV need at ICU admission (adjusted OR= 14.036, 95% CI 1.337-153.111, p=0.028). The length of ICU stay, time to death and rate of complications were not impacted by the presence of cancer. Conclusions: In this study critical cancer patients with COVID-19 had an increased risk for IMV need at ICU admission but not for IMV need during all-length ICU stay or mortality rates. Despite evolving more rapidly to respiratory failure (RF) cancer patients did not have significant increase on mortality, stressing the importance of aggressive treatment in this group of patients.

ABSTRACT

IntroductionResearch following the Covid-19 pandemics has shown that psychological reactions to the pandemic and its constraints can vary significantly depending on personality. One of the traits that has not been studied yet, but can play a harmful role in the COVID-19 psychological impact is perfectionism. This trait, characterized by setting excessively high standards of performance and striving for flawlessness, has increased in recent years and is considered a transdiagnostic process involved in several (mental) health problems (Curran & Hill 2019).ObjectivesTo analyze the role of Perfectionism in the levels of fear of COVID19 and of perception of infection risk by COVID-19.Methods234 adults (75.6% women;mean age=29.53±12.51) completed an on-line survey with the Portuguese validated versions of Covid-19 Perceived Risk Scale (C19PRS;Pereira et al. 2020), Fear of COVID-19 Scale (FC19S;Cabaços et al. 2020) and Big Three Perfectionism Scale (BTPS;Garrido et al. 2020). SPSS was used to perform correlation and regression analysis.ResultsPerceived Risk and Fear of COVID-19 were significantly correlated with perfectionism (.243, .228, respectively) (both, p<.01). Perfectionism explains 5.5% (Adjusted R2) of the FC19S variance (Beta=.243, p<.001) and 4.8% of the C19PRS variance (Beta=.228, p=.01).ConclusionsThis study provides preliminary, but completely innovative evidence that perfectionism contribute to the psychological impact of Covid-19 pandemics. In the near future we will test the hypothesis that the nature of unpredictability and the limitations imposed by the global crisis may be exacerbating the already high levels of psychological distress that affect negative perfectionists.

ABSTRACT

IntroductionRisk perception of COVID-19 is potentially a significant determinant of the pandemic evolution and the public’s response to it. Acceptable levels of risk perception can be considered good for people to effectively fight the pandemic and adopt preventive health behaviors while high levels of risk perception may be damaging. Recently, Yıldırım&Güler (2020) developed the Covid-19 Perceived Risk Scale (C19PRS) to measure this construct.ObjectivesTo analyze the psychometric properties of the C19PRS Portuguese version, namely construct validity, internal consistency and convergent validity.MethodsA community sample of 234 adults (75.6% women;mean age= 29.53±12.51;range:16-71) completed an on-line survey with the Portuguese versions of the CPRS and the Fear of Covid-19 Scale (FCV-19S;Cabaços et al. 2020). The total sample was randomly divided in two sub-samples: sample A (n=117) was used to perform an exploratory factor analysis/EFA;sample B (n=117) to make a confirmatory factor analysis/CFA.ResultsEFA resulted in three components. CFA revealed that the second-order model with three factors presented good fit indexes (X2/df=1.471;CFI=.959;GFI=.948;TLI=.932;p[RMSEA≤.01]=.065). CPRS Cronbach alphas was α=.687;for F1 Worry, F2 Susceptibility to Covid-19 and F3 Susceptibility to Overall Morbimortality were α=.747, α=.813 and α=.543, respectively. The total and dimensional scores significantly correlated with FCV-19S (r>.30, p<.01).ConclusionsThis study provides evidence for the validity and reliability of the Portuguese version of CPRS, which will be used in an ongoing research project on the relationship between Covid-19 perceived risk, perfectionism, cognitive processes and adherence to public health measures to contain the pandemic.
