ABSTRACT

Since 2005, and thanks to the fostering of an interdisciplinary team of experts, academics, researchers, activists, engineers or related to it, the International Conference on Engineering, Social Justice and Peace arises, in the search for alternative approaches to make, live and educate in engineering. During this evolution of calendars and geography, fourteen meetings of the Engineering, Social Justice and Peace network had taken place, and number 15 was destined to be exceptional. Unintentionally, the fifteenth meeting had very different circumstances from the previous ones, not due to the ability to convene, or the growing interest in working on engineering committed to nature, society and human beings, but due to a historical situation that has made us rethink what until some time ago we took for granted. This event has been brewing since 2019, under the premise of being held in 2020. With several initiatives of the event, there was a work team, the approval of several presentations, workshops and activities, a tentative schedule, and the approach of the recognition "Technologies for Social Justice." However, nature gave us a warning cry to human beings and the coronavirus appeared on the scene, causing many transformations worldwide. Therefore, the event was postponed until 2021, and adjusted to the virtuality that has accompanied us since the health emergency arose due to the pandemic. In this context, adjustments were made to the composition of the team and the responsibilities assumed by its members. Still, despite the difficulties that this new scenario poses, the commitment to social transformation marked the way forward for the conference. After several meetings and tasks, between June 10 and 12, 2021, the XV International Conference on Engineering, Social Justice and Peace sees the light, with the promises of transforming our society from a diversity of ways of doing and living. This paper seeks to systematize the experience of the organizing team of the conference, so that the successes and errors that they had during the process are transformed into useful learning for the transformation of engineering towards one that is committed to communities.

ABSTRACT

Introduction: The pandemic of SARS-CoV-2 (COVID-19) has caused high rates of morbidity and mortality. The use of adequate diagnostic methods to identify the evolution of this disease is necessary;computerized tomography (CT) is of the main tools by image, with sensitivity of 96-99%. Different studies have created scales to evaluate the extent and severity of lung disease from COVID-19, with a variability in the results. Objective: To evaluate the use of a tomographic scale (TS) to determine the severity of lung affectation in COVID-19. Material and methods: Analytical cross-sectional study including patients with confirmed diagnosis of COVID-19 and initial CT. ATS was used to evaluate the lung affectation, to identify pulmonary pattern and to establish the state of the disease. Statistical analysis consisted in descriptive and analytical statistics (ROC curve). Results: 151 patients, mean age 50 years. The predominant pulmonary pattern was «crazy paving» (46%), identified in the phase of progression. The area under the ROC curve was 0.831 (95% CI: 0.764-0.898), with a cut-off value of 16.5 to discriminate the severe from non-severe affectation, with sensitivity 84% and specificity 74%. Conclusion: The use of TS in initial CT showed an acceptable sensitivity to identify the severity of the disease.

ABSTRACT

Introdução: Na tuberculose pulmonar (TBp), os principais padrões radiológicos são cavitação e nódulos centrolobulares com padrão de árvore em brotamento, predominantemente nos lobos superiores, e espessamento das paredes brônquicas. No entanto, podemos encontrar manifestações radiológicas atípicas como os tuberculomas pulmonares, tornando o diagnóstico, nestes casos, mais desafiador. Geralmente, o tuberculoma pulmonar aparece isolado e ocorre em cerca de 5% dos casos de tuberculose pulmonar. Nódulos múltiplos, que mimetizam neoplasia pulmonar ou metástases, por sua vez, são ainda mais incomuns. Descrição do caso: Trata-se de uma paciente do sexo feminino, 43 anos, hipertensa, asmática e com diagnóstico de espondiloartrite com início do quadro, do qual não soube precisar data, caracterizado por tosse seca diária e eventualmente com secreção branca ou hemoptise, que piora à noite e melhora parcialmente com anti-histamínico. Há cerca de 1 ano e meio, apresentou dor em dorso e precórdio, que piorava ao esforço físico e tosse, sem fatores de melhora. Há 10 meses, apresentou dispneia aos pequenos esforços, quando teve diagnóstico de COVID-19, porém os sintomas pulmonares se exacerbaram progressivamente. Relata também sudorese noturna e perda ponderal de 7 kg em 3 meses. Em março de 2021, realizou PET CT que evidenciou nódulos pulmonares múltiplos em lobos inferiores e superior direito, sem atividade metabólica específica e de etiologia a esclarecer. Foi realizada segmentectomia pulmonar à direita, no entanto a análise histopatológica da peça revelou processo inflamatório crônico e extensas áreas de necrose caseosa em segmento de lobo inferior direito, sugerindo diagnóstico de TBp, sendo encaminhada para nosso serviço especializado. Foi descartado o HIV. Após 4 meses de uso de rifampicina, isoniazida, pirazinamida e etambutol, 4 comprimidos por dia, paciente refere melhora da tosse seca e da sudorese noturna, além de melhora da adinamia e astenia. Comentários: Geralmente, nódulos pulmonares múltiplos são malignos, chegando a responder a 80% dos casos. No entanto, tuberculose pulmonar no Brasil e na região nordeste, deve sempre ser considerada como diagnóstico diferencial, mesmo diante de imagem não típica.

ABSTRACT

Background Worldwide there is an overwhelming amount of information about COVID-19 circulating online, also named infodemic. Misinformation (the unintentional) and disinformation (the intentional) spreading of false information have proven to be very dangerous to public health. Hence, more than ever, people need skills for searching, evaluating and integrating information related to health in daily life, i.e., health literacy. Until now, little is known about the digital health literacy of university students and their information-seeking behaviour. Hence, this study aimed to analyse the associations between university students' digital health literacy and online information queries during the beginning of the COVID-19 pandemic (and infodemic) in Portugal. Methods A cross-sectional study of 3.084 Portuguese university students (75.7% females), with an average age of 24.2 (SD = 7.5), was conducted using an online survey. We used sociodemographic data (sex, age, subjective social status) and the digital health literacy questionnaire adapted to the specific COVID-19 context. Online information queries included the topics related to SARS-CoV-2 and COVID-19 searched by students. Logistic regression models were performed. Results Online information queries (e.g., individual measures to protect against infection, current spread of the virus, current situation assessments and recommendations) were associated with an increased odds of achieving sufficient digital health literacy. Conclusions Online information queries related to epidemiological and public health topics are significantly associated with digital health literacy in times of COVID-19. Further studies are needed, including programs that improve digital health literacy among university students and increase the availability of high-quality content information.

ABSTRACT

Lung diseases have a strong relationship with gastroesophageal reflux disease (GERD). It has been previously demonstrated that conditions such as tracheal stenosis, asthma and even lung transplantation may worsen with reflux and these patients have few symptoms of GERD. With the COVID-19 pandemic, the number of people who needed mechanical ventilation and tracheostomy increased. Our objective was to demonstrate the prevalence of gastro-oesophageal reflux in patients with tracheostomy and describe its characteristics. Methods: Esophageal manometry and 24 h pH-metry was performed in 137 consecutive patients with a tracheostomy already in a chronic phase, independent of symptoms. Inquire on respiratory and digestive symptoms was also carried out at the time of the examination. Prevalence of gastroesophageal reflux was identified in this population and description of the groups with reflux and without it, as well as comparison between them. Results: of the 137 patients, 49 were male, the average age was 40.94±17.3 and the bodymass index was 26.3±4.85. The prevalence of gastroesophageal reflux was 45.2%. Baseline characteristics were similar between the groups with and without reflux. In the reflux group, the mean DeMeester score was 36.5±20.8 and the presence of lower sphincter hypotonia was found in only 31% of the patients and was not correlated with reflux between the groups (p=0.285). Regarding the symptoms, 48% had heartburn symptoms and only 30% had a combination of typical symptoms (heartburn + regurgitation). Conclusion: The presence of tracheostomy is related to an increased prevalence of reflux, even without typical symptoms most of the time. The mechanism for this is still unknown, perhaps the altered respiratory dynamics has a role. These patients should be investigated with functional exams if they develop any condition that may be affected by reflux.

ABSTRACT

Pneumonia is an acute pulmonary infection whose high hospitalization and mortality rates can, on occasion, bring healthcare systems to the brink of collapse. Both viral and bacterial pneumonia are uncovering many gaps in our understanding of host-pathogen interactions, and are testing the effectiveness of the currently available antimicrobial strategies. In the case of bacterial pneumonia, the main challenge is antibiotic resistance, which is only expected to increase during the current pandemic due to the widespread use of antibiotics to prevent secondary infections in COVID-19 patients. As a result, alternative therapeutics will be necessary to keep this disease under control. This review evaluates the advantages of phage therapy to treat lung bacterial infections, in particular those caused by the Gram-positive bacteria Streptococcus pneumoniae and Staphylococcus aureus, while also highlighting the regulatory impediments that hamper its clinical use and the difficulties associated with phage research.

ABSTRACT

Objective: To describe the autonomic and SNC manifestations of patients with coronavirus disease 2019 (COVID-19) and happy hypoxemia. Background: Happy hypoxemia is the absence of dyspnea despite low oxygen saturation. Several hypotheses for its occurrence include potential viral neuroinvasion, autonomic dysfunction, and cortical ischemic damage. Design/Methods: We studied prospectively nine patients with COVID-19 who arrived at the ER with very low oxygen saturation (50-79%) and no dyspnea complaints. Patients were invited to participate and underwent a full clinical history, brain MRI with gadolinium, and 24H-Holter with spectroscopy while hospitalized and bed-ridden. We used Pearson's coefficient correlation for the correlation analysis. Results: Two patients were excluded from the study because they no longer wished to participate and one because he had FA. we analyzed six patients (66% women) with a mean age of 59 years old (47-83). Two patients had high blood pressure, one patient had a history of tuberculosis, and one had Down Syndrome. Upon arrival at the ER, the mean oxygen saturation was 67% and PaO2 59.3 (47-83). One patient (14%) complain of headache and none of anosmia or ageusia. Four patients underwent a brain MRI that showed gadolinium enhancement of the olfactory bulbs and white matter lesions. One patient also had a left insular lesion. Three patients had abnormal SDNN<100 (83ms, 30-146), and one had RMSSD <15. Vagally mediated changes reflected in HRv were significantly lower in patients with lower blood O2 saturation (SDDN p=0.002, r=.95, HF p=0.009, r=.92, LF/HF ns, -0.42). Conclusions: Patients with happy hypoxemia had decreased heart rate variability that correlated with the degree of hypoxemia, suggesting altered modulation of vagal tone and autonomic dysregulation. All the patients had olfactory bulb enhancement. In our patients, hyposmia /anosmia did not correlate with olfactory bulb hyperintensities or happy hypoxemia.

ABSTRACT

Objective: To describe the neurologic manifestations and complications of Mexican patients with confirmed coronavirus disease 2019 (COVID-19). Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was confirmed to have reached Mexico in February 2020. At present, Mexico is one of the most affected countries by the pandemic of COVID-19 worldwide. In the first months of the pandemic, only a few Mexican studies on COVID-19 had been reported. Scarce national data limited our understanding of the unique nuances that may occur in our setting and hindered the interpretation of evidence from other countries in the local context. Design/Methods: In March 2020, the Mexican Academy of Neurology (MAN) launched a national registry to have a clearer picture of the full spectrum of neurologic manifestations and complications of COVID-19 in Mexican patients. This online registry was available to all MAN members. Only patients with SARS-CoV-2 detected by real-time RT-PCR were included in this analysis. Results: At the end of August 2020, 89 patients (31 women, 34.8%) have been included. Their mean age was 50.5±18.8 years. Most cases were reported in central and southern regions (96%). Most patients showed respiratory symptoms (87%) and were admitted to hospital (88%). Among severe neurologic manifestations, vascular etiologies were the most commonly reported: ischemic stroke (n=17), intraparenchymal hemorrhage (n=6), and subarachnoid hemorrhage (n=4). Olfactory and gustatory dysfunctions were reported in 34 and 26 patients. Headache and delirium were reported in 54 and 18 patients. 7 patients had seizures. Meningitis and encephalitis were reported in 2 and 5 patients. 5 cases of Guillain-Barré syndrome were reported;three of them were classified as axonal variants. Neurologic sequelae were reported in 30 patients (33%). 19 (21%) patients died. Conclusions: In this nationwide registry, one in five patients with COVID-19 and neurologic manifestations died. Cerebrovascular insults were the most common severe neurologic manifestations.

ABSTRACT

Background: Although initially considered at higher risk for severe presentations of COVID-19, observational studies with SCD patients have mostly pointed to clinical severity similar to the general population. However, the level of vulnerability of these individuals to become infected and the determinants for their contagion are still uncertain. Aims: To assess the prevalence of SARS-Cov-2 antibodies in SCD patients followed at a Brazilian center and its correlation with phenotypic and socioeconomic determinants. Methods: A questionnaire was applied regarding demographics, socioeconomic status, use of Hydroxyurea, working status and income, COVID-19 symptoms, and the perceptions about social isolation measures. Blood samples were taken for chemoluminescence IgG (anti-N) and IgM (anti-S) anti-SARS-CoV-2 tests (Abbott Architect™, Ireland);specific neutralizing antibody titers were accessed observing the cytopathic effect in cells incubated with patient serum-virus mixture. Results: From Jul/20 to Jan/21, 214 serological tests were performed on135 patients (86% of SCD patients registered at the center): 82 HbSS (61%), 41HbSC (30%), 8Sβ+ (6%), 4Sβ0 (3%);57% male and median age 42 (19-74). 66% were using Hydroxyurea and 4% were on chronic transfusion. In the analyzed period, 61 (45%) patients had vasoocclusive crises;37 (27%) had symptoms suggestive of COVID-19, but only 2 patients had a positive PCR for SARS-Cov-2. When questioned, only12% of patients did not consider themselves vulnerable to infection, and only17% believed that individual and collective protection measures were expendable. In fact, 91% stated that they were able to adopt basic social distance measures, with 76% reporting cancellation of social events and 64% managed to reduce the use of public transport, but only 44% could work or study remotely. Regarding serological evaluation, 57 patients (42%) were tested more than1 time during this period: 46 with 2 tests,11 with ≥ 3 tests. Among all patients,15 had positive results: 9 IgG/IgM+ and 6 IgG+ only, therefore with an overall seroprevalence of11%. Seroconversion was documented for only1 patient during the study period and, interestingly, with no signs and symptoms of infection. Moreover, 2 patients lost positivity for IgG 3 months after the initial positive test. The search for functionally neutralizing antibodies resulted in 9 patients with low titers (□1:40) and only 3 patients with remarkably high titers (≥1:640). There were no correlations between test positivity and education, income, number of household contacts and maintenance of work outside the home;however, serological positivity was associated with older age (40.3 x 22.9, p<.001) and regular use of public transport (Fisher exact test, p=0.02). Only1 patient in this cohort needed hospitalization for COVID-19, including mechanical ventilation and exchange transfusions, but was discharged after14 days Summary/Conclusion: These data attest to the effectiveness of social distancing instructions given to patients in our SCD clinic throughout the pandemic, considering the low overall positivity and only1 seroconversion during the study period. The fact that only1 patient in our center had severe disease agrees with other reports showing less severity for SCD than initially expected. In fact, the transient positivity of serological tests and the low levels of functional neutralizing antibodies in SCD patients may indicate the acquisition of protective immune responses that are not dependent on antibodies and that still need to be better evaluated.

ABSTRACT

During the first months of lockdown due to the Covid-19 pandemic, TikTok was the most downloaded app worldwide, and conquered, just in Portugal, half a million new users, which requires an attentive look from Media Studies. Using the Uses and Gratifications (U&G) as framework, this study aims to map the practices of Portuguese teenagers (13-16) on this platform, exploring the differences between users and content producers. For that purpose, we conducted an online survey to a non-probabilistic sample of 263 TikTok users. Our findings show that 44,5% of the users create content, and they act more strategically, focusing on self-promotion and on the expansion and dynamization of their online community.
