ABSTRACT

Introduction: The pandemic caused by the severe acute respiratory syndrome coronavirus 2 imposed restrictions to movement, generating new work dynamics especially in the education sector, where remote working has become the rule. The overlapping of work-related and domestic tasks and the fear of the virus generated an additional burden to workers, with unknown effects on their quality of life. Objectives: To estimate the quality of life of employees of the education sector who were working remotely during the pandemic caused by the severe acute respiratory syndrome coronavirus 2 and identify associated factors. Methods: This is a cross-sectional study performed with a sample of 317 government employees of a federal university between August 25 2020 and September 11 2020. Standardized questionnaires concerning sociodemographic and economic aspects were constructed using the Google Forms tool. The European Health Interview Survey – Quality of Life 8-item index was used to assess quality of life. Multiple linear regression was used to check for associations between variables using quality of life scores as outcome (alpha value of 5%). This research proposal was approved by the National Research Ethics Commission, with a Certificate of Presentation for Ethical Appreciation No. 33636220.1.0000.0056. Results: The European Health Interview Survey – Quality of Life 8-item index resulted in mean adjusted scores of 3.5 ± 1.9. Quality of life was independently associated with age (β = 0.01, 95% confidence interval 0.00 to 0.02, p = 0.015), physical activity (β = 0.19, 95% confidence interval 0.00 to 0.38, p = 0.049), smoking habits (β = 0.54, 95% confidence interval 0.19 to 0.88, p = 0.002), having a dedicated workspace (β = 0.14, 95% confidence interval 0.02 to 0.26, p = 0.023), performing housework (β = -0.20, 95% confidence interval -0.32 to -0.08, p < 0.001), financial difficulties (β = -0.26, 95% confidence interval -0.40 to -0.12, p < 0.001), and the impact of social distancing at work (β = -0.33, 95% confidence interval -0.47 to -0.19, p < 0.001). Conclusions: The level of quality of life within the sample was reasonable;it was higher among older participants who were physically active and did not smoke, and lower when the socioeconomic situation was unfavorable. This highlights the importance of constructing support strategies while the effects of the pandemic linger. © 2022 Associacao Nacional de Medicina do Trabalho. All rights reserved.

ABSTRACT

Objectives: Due to COVID-19 pandemic, social distancing policies were enacted worldwide, including by the Portuguese official authorities. However, the impact of these measures on maxillofacial trauma and fracture surgical repair remains poorly understood. The aim of this study was to evaluate and compare the incidence and aetiology of facial fractures submitted to surgical repair during 1-year of COVID-19 pandemic versus the previous 4 years, in a level III Trauma Centre located in Lisbon, Portugal. Materials and methods: All emergency episodes registered in our hospital between March 2016 and February 2021 that resulted in patient admittance for surgical treatment of facial fracture were included. Comparative analysis was performed for variables such as fracture type and aetiology. Results: Analysis showed that surgeries performed during the 1st year of COVID-19 were reduced by 37.5 %. Considering only the 75-day lockdown period at the beginning of the pandemic, reduction was even more pronounced and reached-66.7 %. Significant differences in the aetiology were also found, with physical assault and sport accidents relative frequency decreasing. Moreover, despite being systematically the second most common cause of fracture, during lockdown, fall ranked first, over physical assault. The relative frequency of nasal fractures, the most common facial fracture treated in our hospital, decreased during both the 1st year of COVID-19 and the lockdown period, while mandible fractures ranked first during lockdown. Conclusions: Our study shows that COVID-19 pandemic and enacted policies have significantly changed the epidemiology of maxillofacial trauma. © 2022 Elsevier Espana S.L.. All rights reserved.

ABSTRACT

Introduction: Humanity due to COVID-19 is experiencing a complex moment without historical precedents which demands an embracing reflection about teaching and learning process. Human physiology is the science that studies the functioning of the human body;therefore, it is a highly complex discipline, inherent to human existence challenging professor and students in remote learning. Objective: To share the experience and strategies used to foster the bond and interactivity during remote human physiology discipline offered to undergraduate students in biology, biomedicine, nursing and medical physics at Unesp in Botucatu. Methods: Since the suspension of presential activities, the professor established communication by email with the classes (133 students) aiming at welcoming and maintaining the institutional bond. The starting point for remote education was to verify: 1) accessibility;2) interest in remote education;3) preference for virtual learning environments (VLE) and class format (synchronous or asynchronous). After that, the discipline of human physiology presented the results of this questionnaire to students and organized a proposed schedule of activities that was discussed and reformatted with the active participation of students via synchronous meeting using the Google Meet tool. After the collective construction of the pedagogical contract, Google Classroom was established as VLE and the discipline was offered remotely following the systematic: 1);weekly asynchronous availability of lessons recorded in a reduced format;2) list of exercises contextualized with motivational cases based on the clinic and everyday physiological situations;3) suggestion for free accessible reading using Unesp's collection of e-books;4) synchronous weekly meeting not mandatory for mutual reception, on-call doubts and dynamics of content fixation using 'gamification' strategies of learning (Kahoot) and collective construction of knowledge (motivating cases discussed in online groups through document sharing via Google docs). Results: The initial questionnaire applied to students showed that 83% of students were interested in performing remote activities, signaling a preference for asynchronous classes that respected the diversity of scenarios experienced by students who were now reframing the space from home to dedicate time, physical space and emotional conditions to learn. The remote physiology teaching was first applied to the content previously taught in the presential classroom and served as 'tasting' and training. Adjustments were made based on the student's vision for improving the teaching and learning process of the discipline. The results of this experience show that the students classified the progress of the activities as adequate (grade 5, 0 being very slow and 10 being very fast) and high quality (grade 9 / 0-10). The verification of learning, done through exercises to fix and apply concepts, shows a performance of 78% to 89% by the students. The feedback of the exercises by the teacher attributed a formative character to the activities which had more than 98% adherence by the students. Conclusions and Support: The remote experience of the discipline of human physiology shows that the diversified pedagogical construction of teaching strategies with the participation of the student humanizes the teaching and learning process, valuing the view of the student who starts to appropriate the process as a co-author.

ABSTRACT

While living in a digital era, both teachers and students of Engineering Courses were not ready for the drastic change associated with the Covid-19 first confinement (March 2020). This forced change from a presential mode to a fully online mode provided teaching/leaning difficulties as well as new opportunities. Moreover, as most engineering courses require laboratory practice, on-line teaching raised additional challenges. This paper reports two different experiences in two different Control Engineering university courses in the North of Portugal. The goal is to share some learning tools that are particularly relevant in the pandemic time we are living: pocket-sized laboratory kits that students can easily take home and experience real-world control contents;an open Mural that can serve as an exchange of knowledge. Perceptions received both from students and lecturers regarding these two experiments are presented. © 2021 IEEE.

ABSTRACT

Investments, sustainability and technology are the main aspects pointed out by Smart Tourist Destinations [DTI] to become competitive. However, they do not take into account the hospitality bonds between individuals/groups in their spaces, nor do they address issues related to interpersonal relationships. Added to this scenario, the observation of hospitality by managers, public or private, has become even more affected by the need for social isolation due to the worldwide contamination of the Coronavirus. In this sense, the present work used as object of analysis the data related to the impact of the pandemic available on the municipality of S..o Paulo and aimed to verify through content analysis, as well as measures of social distance, regardless of its intensity, modified and, possibly will continue to modify, the perspective of how the characteristics of hospitality are manifested in the face of this new reality.

ABSTRACT

This work aims to present part of the master's dissertation "Interfaces of Social Memory", defended by the author in 2017, expanding the reflections, to think about the field of social memory and cultural heritage from the Covid-19 pandemic. Through the characterization of digital culture, cyberculture, cybrid culture, interface culture and memory culture, it recognizes the movement of virtualization of memory and the interface of culture that makes humanity immerse itself in screens and networks, real-time and cyberspace. It presents four museological phenomena and one memorialistic phenomenon to reflect on the virtuality/actuality of museums, and the virtual forms of memorialization emerging from cyberculture. It considers the role of the interfaces of social memory in the virtual/actual processes of musealization and memorialization since they have the potential to enable the dialogue between historical memory and living memory, absorbing the notion of place of memory and memory medium.

ABSTRACT

Introduction: Coronavirus disease 2019 (COVID-19) has become one of the more dramatic health problems in the century. This disease has enormous consequence for the health care worldwide. In addition to high mortality rate, patients recovered from COVID-19 present short and long-term cardiovascular sequelae including chest pain, myocardial dysfunction, arrhythmia, dyspnea, breathlessness, postural tachycardia syndrome, and thrombotic complications. The explanations for these clinical manifestations are still uncertain but can involve a constellation of physiological alterations. Hypothesis: To test if COVID-19 survivors have augmented sympathetic outflow, diminished endothelial function, elevated aortic stiffness, and reduced physical capacity compared to healthy individuals. Methods: Nineteen COVID-19 survivors [age: 47.0±2.3 years, BMI: 30.1±1.2 Kg/m2] and eighteen well-matched healthy controls (age: 44.0±2.0 years, BMI: 28.4 ±1.2 Kg.m2] were included in study. COVID-19 survivors were evaluated within 6 months of original diagnosis by RT-PCR. Muscle sympathetic nerve activity (MSNA) from fibular nerve (Microneurography), brachial artery flowmediated dilation (BAFMD;Doppler-Ultrasound), carotid-femoral pulse wave velocity (cf-PWV;Complior), beat-to-beat blood pressure (Peripheral BP;Finometer), heart rate (HR;Electrocardiography) and peak oxygen uptake (VO2peak, Cardiopulmonary exercise testing) were measured in both groups. Results: MSNA was higher in COVID-19 survivors compared to controls (33.0±1.0 vs. 22.0±1.0 bursts/min, p=0.001). Both BAFMD and VO2peakwere lower in COVID-19 survivors compared to controls (4.6±0.7 vs. 8.2 ±0.8%, p=0.005 and 22.2±1.5 vs. 29.7±1.6 mL/Kg/min p=0.001, respectively). Although COVID-19 survivors had greater cf-PWV than controls (8.6±0.5 m/s vs. 7.4±0.4 m/s, p=0.03), BP and HR were not different between groups. Conclusions: Our study revealed that patients recently recovered from COVID-19 have abnormal neurovascular control, vascular alterations and reduced physical capacity. These findings strongly indicate the need of further long-term investigations to uncover cardiovascular sequelae provoked by COVID-19.

ABSTRACT

BACKGROUND AND AIM: Among the most common symptoms of COVID-19 is taste dysfunction, which has a ranging clinical presentation. As well as its pathophysiology remains to be unclear, there is not enough information about the efficacy and safety of the available treatments. This study aims to report a series of cases using PBMT for the management of COVID-19-related taste impairment. CASE SERIES: 8 female and 2 male patients sought medical help for taste impairment (either partially or completely) after COVID-19 infection. Photobiomodulation therapy (PBMT) on the tongue mucosa was then proposed but with 3 different protocols. Taste perception at baseline and before every laser session was evaluated using a visual analog scale. Irrespective of the PBMT protocol, taste recovery was noted in all cases but with varying degrees of improvement. CONCLUSION: given the high prevalence rates of taste dysfunction in COVID-19 patients and the lack of information about the available treatments, PBMT seems to be a promising therapeutic modality but not dependent on the total number of laser sessions and the interval between them. The choice of the most suitable laser protocol as well as the knowledge of the exact photonic mechanisms, however, need to be better studied.

ABSTRACT

Background Annual influenza vaccine uptake is recommended by the Portuguese General-Directorate of Health to certain priority groups. In 2020, amidst the COVID-19 pandemic, some exceptional measures were adopted to operationalize the Portuguese influenza vaccination campaign, like the extension and phasing of the vaccination period. No major changes were introduced in the vaccination of healthcare workers. In Baixo Tâmega health cluster (Portugal), it was perceived that these workers' vaccine uptake had markedly increased in 2020-2021. This study aims to compare their influenza vaccination coverage rates in 2020-2021 to the last 10 seasons. Methods A cross-sectional study of the vaccine uptake among the health workers of Baixo Tâmega health cluster was developed. A descriptive analysis was carried out, calculating annual influenza vaccination coverage rates from 2010-2011 to 2020-2021, in doctors, nurses and other health workers. Inferential analysis was performed through chi-squared tests in IBM SPSS Statistics 27.0.1.0., considering significant p-values<0.05. Results The difference between health workers 2020-2021's influenza coverage rate and the last season's average rates was 22.81%. Before 2020-2021, average vaccination coverage rates were 51.60% (standard deviation 7.34%, 44.26-58.94%), 60.44% (standard deviation 4.12%, 56.32-64.56%) and 51.20% (standard deviation 7.66%, 43.54-58.86%), in doctors, nurses and other health workers, respectively. In 2020-2021, vaccination rates significantly increased to 79.34%, 79.52% and 74.24% in doctors, nurses and others, respectively (p < 0.001). Conclusions Influenza vaccination uptake increased in 2020-2021 among health workers. Further studies should be developed to evaluate this tendency on a larger scale and to better understand its associated factors, which could have been unstructured awareness-raising campaigns, perception of protection against COVID-19 or avoidance of COVID-19-like symptoms and coinfection. Key messages Influenza vaccination coverage rates increased in 2020-2021 among the healthcare workers of a Portuguese health cluster. The COVID-19 pandemic may have contributed to the increase in the influenza vaccination coverage rates.

ABSTRACT

ObjectivesThe objective is to assess the impact of COVID-19 pandemic on the care of gynecologic oncology patients.MethodsThis is a retrospective cohort study of all gynecology oncology new patients treated at Brasilia’s University Hospital - Brazil. We compared to periods: pre-COVID-19 (March 2019 to February 2020) and during COVID-19 pandemic (March 2020 to February 2021).ResultsThere was a 53% reduction in patients with gynecological cancer undergoing treatment at our hospital. The total of surgeries performed was 40 pre and 18 during the pandemic period, a reduction in the surgical volume by 55%. The most operated tumor in the pre-pandemic period was cervix and during was an equal number of surgeries for cervix, endometrial and ovarian cancer. Admissions for chemotherapy or radiotherapy also decreased by 52%. A total of 78 patients underwent cancer treatment before and 37 during the pandemic. The most frequently treated tumor is cervical cancer, with 53 cases in the pre and 26 during the pandemic, followed by ovarian cancer with 14 cases before and only two during the same period. The median waiting time between diagnosis and surgery was 4.44 days longer during the pandemic, as well as the median time to start chemo and radiotherapy was also longer during the pandemic period.ConclusionsWe observed a significant decrease in the number of gynecological cancer patients undergoing treatment during the COVID-19 pandemic. Our results will help health professionals to understand the indirect consequences of the pandemic and the role of women’s health care services in minimizing these consequences.

ABSTRACT

Olfactory dysfunction is commonly seen in COVID-19 patients; however, little is known about the pathophysiology and management. The present study aimed to report a series of cases in which three protocols of intranasal photobiomodulation therapy (PBMT) were used for COVID-19-related olfactory dysfunction. Irrespective of the PBMT protocol, olfaction recovery was noted in all cases but with varying degrees of improvement. Although intranasal PBMT seems to be a promising therapeutic modality, more research is needed to better define effectiveness.

ABSTRACT

Background: Locally advanced head and neck cancer (HNC) treatment promote toxicities that compromise patient’s quality of life (QoL) and treatment efficacy. Exercise training (ET) benefits are reported for many cancer types. To study this supportive care strategy in HNC patients, we designed a two-phase research project: 1) prospective observational cohort study to analyze treatment toxicities and ET preferences;2) randomized-controlled trial to test an ET program (FIT4TREAT). Here we present the results of phase I. Methods: Planned enrollment was 20 patients with stage III/IV HNC proposed for multimodal treatment with curative intent. Patients were assessed in 3 moments: baseline (M0), at the end of treatment (M1) and at 4 months follow-up (M2). Primary endpoint was QoL, evaluated by EORTC QLQ-C30 questionnaire. Secondary endpoints: dysphagia (EAT-10, FOIS), nutritional status (PG-SGA), cognitive function (MoCA), handgrip strength and 6-minute walk test (6MWT). Due to COVID-19 pandemic the study was suspended in March 2020. Comparative analysis (M0 vs M1) took in consideration 7 patients submitted to radical chemoradiotherapy (CRT). Results: From June 2019 to March 2020, 21 patients were recruited (95% men, median age 54 years). The majority recognized the health benefits of an ET program. Most patients were willing to participate in an ET program before (33%), during (52%) and/or after (67%) treatment. The most common exercise preferences were a frequency of 2 times/week, low intensity, 15-30 min/bout. The table shows the acute impact of radical CRT (n=7). [Formula presented] Conclusions: HNC patients are a vulnerable population. Radical CRT declines QoL, physical and nutritional status. These results encouraged the development of ET program FIT4TREAT, which will start recruiting during 2021. We expect to optimize patients’ physical fitness and achieve more efficacy with less toxicity. Legal entity responsible for the study: The authors. Funding: Has not received any funding.

ABSTRACT

The new coronavirus became a severe health issue for the world. This situation has motivated studies of different areas to combat this pandemic. In software engineering, we point out data visualization projects to follow the disease evolution, machine learning to estimate the pandemic behavior, and computer vision processing radiologic images. Most of these projects are stored in version control systems, and there are discussions about them in Question & Answer websites. In this work, we conducted a Mining Software Repository on a large number of questions and projects aiming to find trends that could help researchers and practitioners to fight against the coronavirus. We analyzed 1,190 questions from Stack Overflow and Data Science Q&A and 60,352 GitHub projects. We identified a correlation between the questions and projects throughout the pandemic. The main questions about coronavirus are how-to, related to web scraping and data visualization, using Python, JavaScript, and R. The most recurrent GitHub projects are machine learning projects, using JavaScript, Python, and Java. © 2021 IEEE.

ABSTRACT

IntroductionDue to the current global background of the COVID-19 pandemic, mental health is an important factor to be promoted. In spite of the subjectivity of the psychological impact brought by this pandemic, the population has undergone several sudden and meaningful changes in psychic integrity. Therefore, the League of Psychiatry and Mental Health of a Brazilian public university emerges with the aim of complementing the curriculum of Psychiatric Medicine, along with promoting mental health inside and outside the university.ObjectivesHold online events and disseminate informative material to help students, mental health professionals and general community interested in the topic.MethodsThe League did a member recruitment with academics from different health areas, who prepared and published booklets and folders with informations promoting mental health. And also, promoted speeches on online platforms from May 2020 to October 2020 with psychiatrists, psychologists and renowned professionals in Brazil.ResultsEighteen lectures were held on topics such as “Grief in the pandemic and its implications in mental health”;“Preventing suicide in the pandemic”, among others, that had a relevant role for those who were in a vulnerable emotional state at the time. As for publications, a national reach was possible, which served as a source for the cultivation of a good psychic health to face the pandemic.ConclusionsMore than 13.600 people participated in the promoted proposals, In addition to providing positive feedbacks to the League, with the improvement of knowledge in the field of Psychiatry and Mental Health, reaching the proposed objectives.

ABSTRACT

With the COVID-19 pandemic, multiple transformations succeeded, including the demand for ICU mechanical ventilators, the main equipment to meet the most serious manifestations of the disease. The mechanical ventilators companies, however, were unable to respond to the new volume of orders due to logistical, manufacturing, design and financial problems. Emphasizing the scope of ergonomics, works published within the last 15 years that analysed the interfaces of respirators were reviewed, and, as a result, it was possible to verify the various failures of human factors existing in mechanical ventilators. The pandemic scenario, because of the observed consequences, highlighted the importance of a good interface, as well as the simplification of design, which can bring advantages not only for moments of crisis but also for the common hospital routine. It was concluded that, due to their aptitudes, human factors and design are vital disciplines for proposing solutions to the project problems of respirators highlighted during the pandemic. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.

ABSTRACT

Faced with the pandemic caused by Covid-19, with recommendation of social isolation, large part of the population with lower purchasing power, living in the peripheries of Brazil, has faced difficulties in meeting the social isolation recommended by the World Health Organization. In these spaces, sociabilities are exercised in public areas of the city, such as street markets, stage of various social, cultural and economic dynamics. With various sounds, street markets mark the local soundscape. This study analyzes the sound impact caused by the commercial nucleus of one of the largest street markets in the State of Alagoas and the relationship of this impact with the acoustic perception of users, from the scenarios: before and during the pandemic. This is the Tabuleiro Market, located in Maceió, Alagoas, Brazil. The methodological steps were applied: characterization of the object of study, land use and occupation;survey of objective sound data (acoustic measurements) and subjective data (questionnaires applied to users). Results indicate that even in the face of the pandemic, this street market still resists. For users, sounds related to the buying and selling process are taken as a natural part of the street market, so that its absence would rule it out. © Proceedings of 2020 International Congress on Noise Control Engineering, INTER-NOISE 2020.

ABSTRACT

By modelling the evaporation and settling of droplets emitted during respiratory releases and using previous measurements of droplet size distributions and SARS-CoV-2 viral load, estimates of the evolution of the liquid mass and the number of viral copies suspended were performed as a function of time from the release. The settling times of a droplet cloud and its suspended viral dose are significantly affected by the droplet composition. The aerosol (defined as droplets smaller than 5 µm) resulting from 30 s of continued speech has O(1 h) settling time and a viable viral dose an order-of-magnitude higher than in a short cough. The time-of-flight to reach 2 m is only a few seconds resulting in a viral dose above the minimum required for infection, implying that physical distancing in the absence of ventilation is not sufficient to provide safety for long exposure times. The suspended aerosol emitted by continuous speaking for 1 h in a poorly ventilated room gives 0.1-11% infection risk for initial viral loads of 10 8 - 10 10 copies ml l - l , respectively, decreasing to 0.03-3% for 10 air changes per hour by ventilation. The present results provide quantitative estimates useful for the development of physical distancing and ventilation controls.
