ABSTRACT
The pandemic caused by COVID-19 impacted the entire world, but the significant challenges to be faced during this crisis opened an opportunity for organizations to evolve toward a digital transformation. Educational institutions were a concrete example of the use of technologies, which were abruptly incorporated into the teaching–learning model. Although this initiative was initially a challenge for teachers and students, it has now become a tool for new innovative teaching models, such as hybrid, online, and flexible models. The impact of technology used in education has been beneficial due to emerging technologies (virtual reality, augmented reality, games, web applications, mobile applications, etc.), which have served as tools to facilitate and motivate studying. These educational trends contribute directly to the fourth Sustainable Development Goal (SDG). This research analyzes whether the use of a web application, as a support in the educational model, can make students better understand the subjects of network infrastructure and be more efficient when configuring equipment in a data network. Therefore, this research is based on the design of an educational web application based on Python libraries, which allows the configuration of networking equipment based on the concept of network automation with the application of a graphical user interface (GUI). The web application can be deployed with communication equipment or in conjunction with the GNS3 simulator. This versatility allows this web tool to be applied to the teaching of network equipment configuration in any mode of study (classroom, online, hybrid, or flexible). The results obtained in this research are encouraging and open the way for the implementation of network automation and Python libraries for educational applications that can be important tools within the teaching and learning models of higher education. © 2023 by the authors.
ABSTRACT
Introduction: The COVID 19 pandemic, associated with confinement and social isolation, seems to have impacted the course of many mental disorders in children and adolescents. Specifically, it has created a global context likely to increase eating disorders' (Eds') risk and symptoms and to decrease factors that protect against EDs. Previous studies have highlighted a link between mentalizing deficits and clinical problems. This study aims to compare Covid-Period vs. NON-Covid Period adolescent patients affected by Anorexia Nervosa (AN) considering their psychopathological symptoms and their mentalizing capabilities. Method(s): 206 female adolescents (aged between 12 and 17 years) affected by AN were recruited from the Service for Eating Disorders at S. Gerardo Hospital in Monza. Exclusion criteria were the presence of intellectual disabilities and neurological disorders. The first group of 94 subjects was recruited between September 2018 and February 2020 (NON-Covid Period), and the second group of 112 individuals was recruited between August 2020 and May 2022 (Covid Period). The following instruments were administrated: EDI-3 (Eating Disorders Inventory-3) was used to provide a standardized clinical evaluation of symptomatology associated with eating disorders;SCL-90R (Symptom Checklist 90- Revised) was used to assess psychological problems and psychopathological symptoms;Reflective Functioning Questionnaire (RFQ) was used to assess mentalizing skills, considering that Reflective functioning (RF) is the operationalization of the mental processes underlying the capacity to mentalize. Result(s): A preliminary analysis of data showed worse values in primary and composites scales of EDI-3, higher levels of general psychopathological suffering (SCL-90 composite scales) and more marked levels of hypo-mentalization (RFQ-u) in the Covid-Period subjects: the differences were statistically significant. Conclusion(s): Although these results are still preliminary, it is possible to hypothesize a correlation between marked levels of hypo-mentalization and higher rates of psychopathological suffering and a worse clinical pattern of Anorexia Nervosa. It is also possible to hypothesize that a preventive intervention to strengthen the reflexive functions may result protective factor against the onset of more severe clinical manifestations and comorbidities;mentalizing abilities could be an important target for therapeutic interventions. Further research should be conducted on larger samples and with a new assessment after treatment interventions.
ABSTRACT
INTRODUCTION: To examine the patient-centered outcomes and the occurrence of lung fibrotic changes on Chest computed tomography (CT) imaging following pneumonia-related acute respiratory distress syndrome (ARDS). We sought to investigate outpatient clinic chest CT imaging in survivors of COVID19-related ARDS and non-COVID-related ARDS, to determine group differences and explore relationships between lung fibrotic changes and functional outcomes. METHOD(S): Retrospective practice analysis of electronic health records at an ICU Recovery Clinic in tertiary academic medical center. RESULT(S): One-hundred four patients with mean age 54 +/- 13 and 52% male were included (n=74 COVID-19 and n=30 non-COVID groups). There were no differences for age, sex, mechanical ventilation duration, tracheotomy, or sequential organ failure assessment (SOFA) scores between two groups. Six-weeks after hospital discharge, fibrotic changes visualized on CT imaging occurred in a higher proportion of COVID-19 survivors (69%) compared to non-COVID (43%, chi2 = 5.6, p = 0.018). In general, across both groups, patients with fibrotic changes (n=64) were older, had a lower BMI, and had longer duration of mechanical ventilation. Overall, patients performed poorly on six-minute walk test (44 +/- 27% of predictive distance), had poor respiratory function (FEV1% = 66 +/- 27% and FVC% = 65 +/- 20%), and had high occurrences of anxiety, depression, emotional distress, and mild cognitive impairment regardless of presence of fibrotic changes. CONCLUSION(S): Patients surviving pneumonia-ARDS are at high risk of impairments in physical, emotional, and cognitive health related to Post-Intensive Care Syndrome. Of clinical importance, pulmonary fibrotic changes on chest CT occurred in a higher proportion in COVID-ARDS group;however, no differences were measured in spirometry or functional assessments at six weeks post hospital discharge. Whether COVID infection imparts a unique recovery is not evident from these data but suggest that long-term follow up is necessary for all survivors of ARDS.
ABSTRACT
Background. Clinical trial demonstrated that SARS-CoV-2 vaccines have the ability of reduce mortality and morbidity due to COVID-19. The aim of this study is to describe the effect of vaccination in term of mortality, type of ventilation and ICU admission among patients hospitalized for COVID-19 from May to December 2021 in a Ligurian Hospital. Methods. This is a retrospective, single-center study conducted in San Martino Hospital (Genoa, Italy), including patients >= 18 years hospitalized for COVID-19 in Infectious Disease and Emergency Units from 1st May to 31st December 2021. We collected demographical data, multimorbidity and disability score, vaccination time ("vaccinated" all patients hospitalized >= 14 days after first dose or >= 7 days after second/ third dose), therapy for COVID-19, mortality at 7 and 30 days, ICU admission, ventilation type. Characteristics of vaccinated (group A) versus non vaccinated (group B) patients were compared using Chi-squared/Fisher's exact test for categorical variables and t-test /Kruskal-Wallis test for the continuous ones. Cox proportional hazards models for death at 30 days were performed as univariate analysis as well as adjusting for age, Cumulative Illness Rating Scale [CIRS], gender, Remdesivir, Monoclonal antibodies, Tocilizumab use. Results. Overall, 405 patients SARS-CoV-2 infected were enrolled. Data about timing of vaccination were available for 360 patients (89%). We compared clinical characteristics and outcomes of group A (32%) versus group B (68%). In group A patients were older (p< 0.001) and frailer (higher CIRS score and lower Barthel index, p< 0.001) than in group B. Among patients requiring oxygen, 76 (31.5%) in group B vs 26 (22.41%) in group A needed high flow ventilation (p=0.036);33 (13.52%) vs 3 (2.59%) respectively were admitted to ICU (Figure 1). Mortality at 30 days after hospitalization was higher in group A at univariate analysis [HR(95%CI) 1.44(0.82;2.53), p=0.208], lower at multivariate analysis [0.57(0.31;1.02), p=0.059]. Conclusion. The results of this study confirm that SARS-CoV-2 vaccination reduces rate of admission to ICU and 30 days mortality among patients hospitalized for COVID-19. In our cohort mortality among vaccinated patients remains high and we hypothesized this is due to high frailty of evaluated population.
ABSTRACT
Introduction: The COVID-19 pandemic represents an epidemiological and psychological crisis (APA, 2020). In this context, although emerging adults are less likely to get COVID-19, they might have suffered from the national lockdowns over the last year, as they are indeed involved in a crucial development period wherein interpersonal relationships undertake a fundamental function in their psychological well-being. To this end, mentalizing abilities and emotion dysregulation may play a crucial role as possible salutogenic or pathogenic factors on the onset of psychiatric symptoms during the three waves of the COVID-19 pandemic. Objective(s): 1) To examine the relationship between emotion dysregulation assessed at the end of the first wave of COVID-19, mentalizing assessed during the second wave, and psychiatric symptoms levels assessed during the third wave. 2) To examine the moderation role of mentalizing within the relation between emotion dysregulation and psychiatric symptoms. Method(s): Participants were 83 non-clinical emerging adults (Mage=22.18, SD=4.36;57.8% females). Measures applied were Difficulties in Emotion Regulation Scale (DERS) to examine emotion dysregulation, Reflective Functioning Questionnaire to examine mentalizing (RFQ-uncertainty;RFQ-certainty) and Symptom Checklist-90-Revised (SCL-90) to examine psychiatric symptoms (Global Severity Index, GSI). Result(s): DERS-total score (r=.31, p=.03) and both RFQ-uncertainty (r=.41, p<.01) and RFQ-certainty (r=-.33, p=.02) are associated with GSI. Secondly, a significant moderation role by RFQ-u emerged within the relation between DERS-total score and GSI (DELTAR2=.067, beta=.001, SE=.00, CI[.000, .002]). Conclusion(s): These results suggest that mentalizing and emotion dysregulation may play a pivotal role in the onset of psychiatric symptoms during the COVID-19 pandemic. Clinical implications are discussed.
ABSTRACT
Background: The spread of COVID-19 had a strong impact in north-east Italy especially during 2020 and in the frst months of 2021. Patients affected by rheumatological disorders are at high risk of infections due to immunosuppressant therapies and a clear immunological imbalance. However, some anti-cytokines such as IL-1 inhibitors proved to be effective in curbing the cytokine storm, frequent feature of severe COVID-19. Objectives: We assessed the SARS-CoV-2 clinical course in 28 patients affected by autoinfammatory diseases, referring to the Autoinfammatory Outpatient Clinic of Padova University;in particular we observed if patients undertaking IL-1 inhibitors (group-1) had a diverse outcome compared to those not on anti-IL-1 drugs (group-2). Methods: Through telephone or e-mail consultancy, 28 patients (18 females, mean age 39.5±15), confrmed to have contracted COVID-19 between March 2020 and January 2022. Twelve patients (42.8%) were affected by periodic fevers (FMF/TRAPS), 10/28 (35.7%) had Adult-Onset Still's Disease, 3/28 (10.7%) had Undiffer-entiated Autoinfammatory Diseases, while 2/28 (7.1%) were affected by BehÇet Disease and one patient had Schnitzler Syndrome. 12 out of 28 patients (42.8%) were undertaking IL-1 inhibitors;8/28 (28.5%) were in therapy with colchicine;2 patients were in therapy with methotrexate and abatacept respectively, and 6/28 (21.4%) received no therapy. All were diagnosed with COVID-19 after molecular nasopharyn-geal swab performed either for the presence of symptoms or close contact with a positive subject. 5/28 patients had the infection after receiving the second vaccine shot, two after the booster dose. All the others had COVID-19 before the vaccine injection. GraphPad5 was used for statistical analysis and Fisher's test was applied. Results: COVID-19 clinical course was benign in 27 out of 28 patients (96.4%);a total of 29 infections were counted due to a case of re-infection;2 patients discontinued the therapy;all the others continued their medications (92.8%). Two patients (7.1%) of the entire cohort were hospitalized, one died. Regarding the major symptoms (fever ≥ 38 C°, cough/respiratory or gastro-intestinal symptoms) no difference was noticed between group-1 and group-2 (p=0.449);despite group-1 required less symptomatic therapy than group-2, the difference was not signifcant (p=0.471). Table 1 summarizes the clinical features exhibited by the patients and the therapies undertaken during the infection. Conclusion: Despite the low sample size, our study is of interest since it proves that the inhibition of IL-1 with both anakinra or canakinumab and the employment of colchicine, an important infammasome regulator, may curb the hyperinfammation typical of COVID-19. Given the promising results obtained with anti-IL-1 and colchi-cine in treating severe COVID-19, it is conceivable a 'protective' role of these drugs in preventing a massive cytokine release. Unsurprisingly, none of our patients but one, had a severe course or fatal outcome after SARS-CoV-2 infection.
ABSTRACT
Co-design methods and toolkits are commonly used to involve people from diverse backgrounds and disciplines in design processes, promoting collaboration, design thinking, shared decision making, and creativity. These methods and toolkits are generally tailored to in-person workshops supported by different physical artifacts (e.g. card-sets) in a shared physical location. Physical co-location and artifacts allow participants to interact in seamless ways, relying on everyday modalities of interaction. The CoViD-19 pandemic has forced many of such workshops online. This required transforming location, methods, toolkits and to rethink interaction among participants. With this workshop we aim to look back at these experiences of transformation and to reflect on the affordances of the physical and the virtual in co-design workshops. What are the challenges of transforming location, methods, and toolkits that are designed for in-person workshops into the digital? In which ways can in-person and virtual workshops co-exist and complement each other? We invite participants to share their experiences and reflect on how to bring together virtual and in-person co-design workshops. © 2022 Owner/Author.
ABSTRACT
Background: About 10% of individuals with mild infection with SARS-CoV-2 suffer from Long COVID-19, defined as signs and symptoms developed during or following COVID-19 that continue for more than twelve weeks and cannot be explained by an alternative diagnosis. In this study, we analyzed the ADCC response and the reactivation of CMV and EBV in Long COVID-19 syndrome, in comparison with patients who completely recovered from mild COVID-19 Methods: 30 patients with Long COVID-19 (Long COVID-19) and 20 individuals who suffered mild COVID-19 and were completely recovered (Recovered) were recruited for this study. Specific anti-SARS-CoV-2 IgG titers were analyzed by direct ELISA and their neutralizing capability was measured by using pseudovirus neutralization assay. Phenotype of CD4+ and CD8+ T cells, NK, NKT, and B cells in peripheral blood was analyzed by flow cytometry. ADCC activity was analyzed using rituximab-coated Raji cells as target. EBV and CMV reactivation in plasma was analyzed by qPCR. Results: 1) 86.6% and 55.50% participants were female in Long COVID-19 and Recovered cohorts, respectively. Median age at COVID-19 diagnosis was 42y(IQR 37-46) and 45y (IQR 28-57), respectively. 2) Similar levels of CD4+ T cells were observed in both groups. However, Tregs were increased 2.8-fold in Long COVID-19 participants (p=0.0007). 3) CD8+ T cells, CD8+TCRγδ and CD8+TCRγδ were increased 1.3-(p=0.0005), 2.0-(p=0.049), and 2.5-fold (p=0.005) in Long COVID-19 individuals. 4) Expression of CD56 in NK cells and CD3-CD56+CD16+ cells were increased 1.7-(p=0.0005) and 1.7-fold (p=0.032) in Long COVID-19, respectively. 5) Specific anti-SARS-CoV-2 IgG titers were increased 2.3-fold in Long COVID-19 individuals (p=0.02) and their neutralizing capacity was increased 4.2-fold (p=0.034) in this cohort. However, ADCC activity was decreased 1.4-fold (p=0.0044). 6) Resting memory B cells were increased 2.3-fold during Long COVID-19, whereas plasmablasts were reduced 3.1-fold. 7) EBV was reactivated in 33.3% of Long COVID-19 individuals (p<0.0001), whereas CMV was not reactivated in any individual. Conclusion: Despite high levels of neutralizing antibodies and cytotoxic immune populations, an impaired antibody-dependent cytotoxic activity was observed in PBMCs from individuals with Long COVID-19. This defective cytotoxic immune response may impede viral clearance, which may also contribute to EBV reactivation observed in these individuals, thereby influencing on the persistent COVID-19 symptoms.
ABSTRACT
Background: Oncohematological patients may have a lower immune response against SARS-CoV-2, both to natural infection and to vaccines. Most studies have focused on the analysis of the humoral response, which means that the information available on the cellular response against SARS-CoV-2 in these patients is limited. Current recommendations include vaccination against SARS-CoV-2 in patients undergoing autologous hematopoietic stem cell transplantation (AHSTC), regardless of whether they have been previously exposed to the virus. These recommendations are based on previous studies with other vaccines. Therefore, it is necessary to analyze the immune response that is developed in these patients in order to make specific recommendations for COVID-19 vaccination. Objective: To study the humoral and cellular immune response before and after AHSTC in patients with oncohematological neoplasms who were exposed to SARS-CoV-2 before the transplantation. Materials & methods: Nine patients with previous exposure to SARS-CoV-2 who underwent AHSTC (Table 1) and 8 healthy donors who recovered from mild COVID-19 were recruited from Hospital Ramón y Cajal and Primary Healthcare Center Pedro Laín Entralgo (Madrid, Spain), respectively. Specific direct cellular cytotoxicity (DCC) of PBMCs from these patients against Vero E6 cells infected with pseudotyped SARS-CoV-2 was determined. The activation of caspase-3 in Vero cells was measured after 1 hour of co-culture with PBMCs, in which cytotoxic cell populations were analyzed by flow cytometry. Antibody-dependent cellular cytotoxicity (ADCC) was analyzed by quantifying the binding of Annexin V to rituximab-coated Raji cells as targets of PBMCs. Results: 1) 66% of AHSTC patients did not develop detectable levels of IgGs against SARS-CoV-2 (Fig. 1). In 33% of these patients with detectable IgG, the titers decreased after AHSTC, as well as their neutralizing capacity (Fig. 1B and C). 2) AHSTC patients showed increased levels of immature B cells (9.5-fold;p=0.0586) and plasmablasts (28.8-fold), in comparison with healthy donors who had mild COVID-19, while naive and resting memory B cells decreased 1.7- and 6.9-fold, respectively. 3) Specific DCC against SARS-CoV-2-infected cells increased 1.5-fold in comparison with healthy donors (Fig. 2A). Cytotoxic populations with NK phenotypes (CD3-CD56+CD16+), NKT (CD3+CD56+CD16+), and CD8+ T cells (CD3+CD8+TCRγδ+) increased 1.9- (p=0.0311), 1.9- (p=0.0592), and 1.6-fold, respectively (Fig. 2B). ADCC increased 2.1-fold in PBMCs from AHSTC patients in comparison with healthy donors (p = 0.0592). Conclusions: Our data show for the first time how the humoral and cellular immune response against the natural infection by SARS-Cov-2 may be modified in patients who were subsequently subjected to AHSTC. Although the humoral response may be reduced after AHSTC, the specific cellular response showed an increased cytotoxic activity. These results could be extrapolated to patients who were vaccinated against COVID-19 prior to AHSTC. Therefore, this information could be useful to define the recommendations for COVID-19 vaccination after AHSTC.

ABSTRACT
This retrospective study describes demographics and outcomes of adult patients with SARS-CoV-2 infection admitted to our ward during the first wave (from February 25 to May 30, 2020) and during the second wave (from August 5 to November 30, 2020). The primary study objective was to evaluate overall in-hospital mortality, which was 21.1% (60/285) vs 10.3% (27/261) (p=.0006). This study seems to corroborate and expand the concept that the second wave of COVID-19 was less deadly than the first. Despite some limitations, the clinical and managerial experience gained during the first wave trained us to handle and control the second one.
ABSTRACT
[Formula presented] Background: Oncohematological patients present a variable immune response against many vaccines, due to the immunodeficiency caused by the disease and its treatment. The experience of vaccination against COVID-19 in oncohematological patients is low and mostly limited to studies of humoral immunity. However, the humoral and cellular immune responses between different oncohematological diseases (OHD) have not been compared. Objective: To compare the humoral and cellular immune responses in four groups of patients with OHD after receiving the first dose of one COVID-19 vaccine. Materials & methods: We recruited 53 patients in four groups according to diagnosis: Chronic Lymphatic Leukemia (CLL) (n=14), Chronic Myeloid Leukemia (CML) (n=11), Multiple Myeloma (MM) (n=15), and Allogeneic Hematopoietic Stem Cell Transplantation (ASCT) (n=13) (Table 1). Samples were collected prior to vaccination and 3 weeks after receiving one dose of COMIRNATY (BioNTech-Pzifer), mRNA-1273 (Moderna), or AZD1222 (AstraZeneca). Twenty-six healthy donors with similar vaccination pattern were recruited. IgG titers against SARS-CoV-2 were quantified by Euroimmun-Anti-SARS-CoV-2 ELISA. Direct cellular cytotoxicity (DCC) was determined against Vero E6 cells infected with pseudotyped SARS-CoV-2, measuring caspase-3 activation after co-culture with PBMCs, in which cytotoxic populations were phenotyped by flow cytometry. Antibody-dependent cellular cytotoxicity (ADCC) analyses were performed using Annexin V on Raji cells as a target. Results: 1) Early humoral response against COVID-19 vaccination in patients with CML was 5.1- (p<0.0001), 2.8- (p=0.0027), and 3.2-fold (p<0.0001) higher than in patients with CLL, MM and HSCT, respectively, and 3.5-fold higher than in healthy donors (p=0.0460) (Fig. 1). 84% of CLL patients did not develop detectable IgG titers. Individuals with OHD developed lower titres of neutralizing antibodies than healthy donors. 2) Unspecific ADCC was overall reduced in patients with OHD, mostly in individuals with ASCT (3.2-fold lower (p<0,0001)), whereas ADCC was reduced 2.2- (p<0.0001), 1.8- (p=0.0040), and 2.2-fold (p<0.0001) in individuals with CLL, CML and MM, respectively (Fig. 2A). However, specific DCC was increased 4.7-, 8.1- (p=0.0189), and 2.1-fold, respectively, in PBMCs from patients with CLL, MM, or ASCT, in comparison with healthy donors, whereas patients with CML showed a very similar response than healthy donors (Fig. 2B). 3) Levels of CD3+CD8+TCRγδ+ T cells were increased 2.2-, 2.1-, 2.7-, and 4.3-fold (p=0.0394) in patients with CLL, CML, MM, and ASCT, respectively, in comparison with healthy donors. CD3+CD8-TCRγδ+ T cells were also increased in patients with OHD, expressing high levels of the degranulation marker CD107a. However, the levels of CD3-CD56+CD107a+ NK cells were reduced 4.2- (p=0.0003) and 3.6-fold (p=0.0010) in PBMCs from patients with MM and ASCT, respectively, in comparison with healthy donors. Conclusions: We found significant differences in the early humoral immune response after one single dose of COVID-19 vaccine depending on the OHD analyzed. It was observed for the first time that the early cytotoxic immune response is efficient in all groups of patients, although superior in those who were not exposed to ASCT. Most cytotoxic activity relied on CD8+ T cells. These data can be useful to determine the efficacy of COVID-19 vaccines in patients with OHD.

ABSTRACT
The Web is essential for education and e-learning. This situation has been boosted by migration to distance education due to the SARS-Co V-2. However, students with disabilities have been seriously affected because online teaching is very often not accessible. For this reason, this research aims to evaluate the accessibility of the homepages of the web portals of the Ecuadorian higher education institutions ranked in the Webometrics with the Web Content Accessibility Guidelines (WCAG) 2.1 of the World Wide Web Consortium. The results obtained determined that the 65 homepages analyzed of the web portals have accessibility errors. Therefore, we concluded that we should adopt the WCAG in the web sites to comply with the Ecuadorian technical regulation RTE INEN 288 'Accessibility for web content.' © 2021 IEEE.
ABSTRACT
BACKGROUND & AIMS: Resting Energy Expenditure (REE) quantitatively describes the calories used to support body function (e.g. breathing, blood circulation, etc.) at resting condition. Assessment of the REE is essential for successful weight management and the understanding of metabolic health. REE is typically determined via indirect calorimetry. Current biomedical indirect calorimetry technologies, utilizing assessment of oxygen consumption (VO2) and carbon dioxide production (VCO2) rates (which are typically in the form factor of a metabolic cart) are bulky and require on-site calibration and/or trained professionals to operate. We introduce a novel wearable medical device with FDA clearance to determine REE accurately, portable, and user-friendly format, which can be used both by health professionals in a clinical environment and by the patient at home. Previously, we have reported the validation of Breezing Med (also named as Breezing Pro™) through Douglas Bag Method, a gold standard for gas exchange measurement, and excellent agreement has been found between the two methods for the determination of REE, VO2, and VCO2 rates (Mora et al., 2020). Now we present the validation of Breezing Med against Medical Graphics (MGC) CPX Ultima™, a FDA 510 k cleared metabolic cart, which principle is based on breath-by-breath analysis. In addition, we present Breezing Med as a tool for daily measurement of metabolic rate by the lay person at home. METHODS: A) The validation study was executed via parallel measurement of 20 healthy participants under resting conditions using both the Breezing Med and the MGC Ultima CPX™ (10 min test). B) Breezing Med measurements were carried out by six subjects at home during stay-at-home order due to COVID-19 for 30 days. RESULTS: A) The resulting measurements from both devices was compared with correlation slope's and R-squared coefficients close to 1. B) Results were recorded and analyzed for variability. The pilot study demonstrated the advantage of Breezing Med device to be easy-to-use at home by lay people, which make the valuable device for telemedicine applications related to weight management from home. CONCLUSIONS: This result shows that the MGC Ultima CPX™ and Breezing Med are substantially equivalent for REE measurement; and an advantage of this device for metabolic assessment under the current COVID-19 pandemic situation, for people with impaired physical mobility, and for those who lives in rural areas or face impediments that limit physical access to care.

With the rise of information technology and digitization, education has been faced with the need to adopt new learning models using technology to create innovative educational methodologies. In addition, due to pandemic restrictions and in order to help contain the spread of the virus (COVID-19), all educational institutions have been forced to switch immediately to online education. The application of augmented reality (AR) in education provides important benefits, such as increased engagement and interactivity, and can help to minimize the negative effects of the disruption of face-to-face education. Therefore, this paper focuses on describing the effect of an augmented reality mobile application (NetAR) that was developed for engineering students as a complement to traditional education. To achieve this objective, an experimental group and a control group were established to work with the application for three weeks for three hours a day. Moreover, there are a number of usability issues with AR that may impact learning effectiveness and motivation. Therefore, the usability of the application was evaluated with the IBM Computer System Usability Questionnaire (CSUQ) tool. The usability results show that users are satisfied with NetAR, and the statistical data from the control group indicate that the application positively affects learning.
ABSTRACT
The COVID-19 pandemic has caused huge impact on public health and significantly changed our lifestyle. This is due to the fast airborne oro-nasal transmission of SARS-CoV-2 from the infected individuals. The generation of liquid aerosolized particles occurs when the COVID-19 patients speak, sing, cough, sneeze, or simply breathe. We have developed a novel aerosol barrier mask (ABM) to mitigate the spread of SARS-CoV-2 and other infectious pathogens. This Aerosol Barrier Mask is designed for preventing SARS-CoV-2 transmission while transporting patients within hospital facilities. This mask can constrain aerosol and droplet particles and trap them in a biofilter, while the patient is normally breathing and administrated with medical oxygen. The system can be characterized as an oxygen delivery and mitigation mask which has no unfiltered exhaled air dispersion. The mask helps to prevent the spread of SARS-CoV-2, and potentially other infectious respiratory pathogens and protects everyone in general, especially healthcare professionals.
