Notification of COVID-19 as an occupational injury by health workers: scoping review

Objective: To identify the publications that discussed COVID-19 as an occupational injury and its notification by health workers.Methods: The search for this scoping review explored national and international literature, between 2020 and 2021, in English, Portuguese and Spanish, in the databases of the Regional Portal of the Virtual Health Library, in MEDLINE through PubMed and in Capes Journal Portal used: Embase, Scopus, Web of Science, CINAHL. The texts were imported into EndNote, duplicates were removed and exported to the Rayyan application, and the articles were included in an Excel spreadsheet with the labels: COVID-19 as injuries at work and Notification of COVID-19.Results: A total of 5665 studies were identified, excluding 2088 duplicates, resulting in 3577 publications, selected by title and . Of these, 3280 did not meet the inclusion criteria, resulting in 297 articles. Of these, 10 were selected for full text analysis because they dealt with COVID-19 as an injury at work and/or notification of this condition by health workers. Two articles were excluded because they were a literature review, remaining 8 as the study's corpus.Conclusion: Although certain countries already recognize COVID-19 as an occupational injury, some workers still have difficulties in relating the SARS-CoV-2 infection with work in health care, characterizing it as an occupational injured. Everyone should be guided and trained regarding the recognition of COVID-19 as an occupational injury and notify its occurrence, since the definition of the infection as a notifiable disease already exists.

Characteristics of patients treated for suicidal behavior during the pandemic in a psychiatric emergency department in a Spanish province

Introduction: Different studies have suggested that psychological, social and economic factors could contribute to an increase in the suicide. That is why the scientific community fear an epidemic of suicides secondary to this crisis. The objective is to evaluate the variables related to suicidal behavior during the two states of alarm and to review if there were sociodemographic or clinical differences with respect to periods prior to the COVID-19 pandemic. Material(s) and Method(s): We compared visits to the emergency room and their characteristics of all patients with suicidal behavior before and after the pandemic in Lerida. Information on sociodemographic status, reason for consultation, diagnosis and characteristics of suicidal behavior was obtained from the electronic medical record. Result(s): No differences were observed in the percentage of suicidal ideation or attempts in the three periods (p = 0.201). The characteristics in the multiple logistic regression associated with suicidal behavior are: being a woman (OR: 1.81 [1.27-2.56]), living with relatives (OR: 1.55 [1.05-2.32]) and have a diagnosis of non-alcohol related substance use disorder (OR: 1.94 [1.09-3.42]). As protective factors, being visited in the emergency room during the second state of alarm (OR: 0.68 [0.48-0.96]) and having depression (OR: 0.67 [0.47-0.96]). Conclusion(s): Emergency care for suicidal behavior did not increase during the pandemic and, in fact, in 2020 completed suicides decreased by almost half in the province. Risk factors for suicide attempt were female gender, living with relatives, and having a substance use disorder diagnosis. Instead, depression was a protective factor.Copyright © 2022

Covid RayScan

The year 2020 was an unprecedented time for all, combating COVID, following precautionary measures and finding a cure for the virus was of utmost importance. As the COVID-19 is here to stay, it is imperative to detect it as early as possible. Our web application (COVID RayScan) is a prediction-based Machine Learning application which can be used by technicians, doctors at hospitals to understand a X-ray or CT-Scan and hence quickly detect if a patient suffers from Covid or not. According to NCBI, it takes 17.4 minutes for a doctor to treat every patient and that metric has increased exponentially with increase in COVID. COVID RayScan with the help of Deep Learning CNN Networks like ResNet50,VGG16,Inception and Xception helps a technician to run the X-Ray/CT-Scan image through our web application to get the desired result which in turn saves the doctor's as well as patients time and make the process much more efficient. © 2022 IEEE.

Long-Term Sequelae of severe COVID-19: Outpatient assessment of radiological and pulmonary function tests

Objective: Identify lung sequelae of COVID-19 through radiological and pulmonary function assessment. Design(s): Prospective, longitudinal, cohort study from March 2020 to March 2021. Setting(s): Intensive Care Units (ICU) in a tertiary hospital in Portugal. Patient(s): 254 patients with COVID-19 admitted to ICU due to respiratory illness. Intervention(s): A chest computed tomography (CT) scan and pulmonary function tests (PFT) were performed at 3 to 6 months. Main variables of interest: CT-scan;PFT;decreased diffusion capacity of carbon monoxide (DLCO). Result(s): All CT scans revealed improvement in the follow-up, with 72% of patients still showing abnormalities, 58% with ground glass opacities and 62% with evidence of fibrosis. PFT had abnormalities in 94 patients (46%): thirteen patients (7%) had an obstructive pattern, 35 (18%) had a restrictive pattern, and 58 (30%) had decreased DLCO. There was a statistically significant association between abnormalities in the follow-up CT scan and older age, more extended hospital and ICU stay, higher SAPS II and APACHE scores and invasive ventilation. Mechanical ventilation, especially with no lung protective parameters, was associated with abnormalities in PFT. Multivariate regression showed more abnormalities in lung function with more extended ICU hospitalization, chronic obstructive pulmonary disease (COPD), chronic kidney disease, invasive mechanical ventilation, and ventilation with higher plateau pressure, and more abnormalities in CT-scan with older age, more extended ICU stay, organ solid transplants and ventilation with higher positive end-expiratory pressure (PEEP). Conclusion(s): Most patients with severe COVID-19 still exhibit abnormalities in CT scans or lung function tests three to six months after discharge.Copyright © 2023

Safety of a mRNA COVID-19 vaccine in patients with indolent systemic mastocytosis

Background: The development of vaccines against coronavirus disease 2019 (COVID-19) and the report of associated allergic reactions has led to growing concern about their safety, especially in populations at risk for anaphylaxis such as patients with systemic mastocytosis. Method(s): We conducted a retrospective descriptive analysis of patients with systemic mastocytosis referred to our Allergy and Clinical Immunology Department, between June 2021 and February 2022, for COVID-19 vaccination. Patients were divided into two groups according to their risk of allergic reaction: low/moderate-risk (no history of severe allergic reaction, with or without a history of allergic disease) and high-risk (history of any severe allergic reaction). All patients were premedicated with 60 mg of oral prednisolone 24 hours and 1 hour prior inoculation, and with an oral antihistamine 1 hour before vaccine administration. Low/moderate-risk patients were monitored for 30 minutes after vaccine inoculation. High-risk patients got a peripheral venous access and remained under medical surveillance for 60 minutes. Result(s): A total of 45 patients were included in the analysis: 62.2% females, with a mean age of 48.8 years (range: 22-85). All patients had indolent systemic mastocytosis subtype, with a median tryptase level of 15.6 ng/mL (range: 4.3-185 ng/mL);11 (24.4%) were in the high-risk group (8 with history of anaphylaxis to hymenoptera venom and 3 with prior drug anaphylaxis). Low/moderate-risk and high-risk groups had similar median levels of serum tryptase (15.5 vs. 16.6 ng/ mL, p = 0.932). All patients received BNT162b2 mRNA COVID-19 vaccine and a total of 118 doses were administered (24.6% in the high risk group). No adverse events, including allergic reactions, after vaccine inoculation were recorded during the surveillance period. Conclusion(s): To our knowledge, this is the largest series reporting safety of a mRNA COVID-19 vaccine in patients with systemic mastocytosis. Our data reinforce the fact that even patients with increased risk for allergic reactions can be safely vaccinated against COVID-19, and that earlier concerns should be abandoned so a widespread immunization can be achieved.

Remote Leadership: A (Re)qualification of School Leaders in Portugal

The COVID-19 pandemic brought about new challenges to schools' organization leaderships and to school leaders. This study, of qualitative nature, aims at understanding the impact occurred in the area of school management, in pandemic times, from the leaders' perspective, in Portugal. The investigation question is: what prevailed during the remote school management of the leader's team amidst the COVID-19 pandemic time? The sample is a video, with 2 min and 47 s, done by the Leader of a Cluster of Schools, in the North of Portugal, within the context of activities related to affection, promoted by the group of Schools' Libraries, entitled "Month of Affections”, when COVID-19 lockdown was mandatory. The content analysis was done using the webQDA® software. All ethical rules were accounted for. The main results are: (i) adaptation and remote management;(ii) challenges to leadership and (iii) vision for the future. It was concluded that, due to the mandatory social distance, the Leader chose for an active and creative virtual presence (re)qualifying his leadership. The concept of this remote leadership kept the organizational balance, leading his co-workers to achieve the defined objectives. The remote leadership will have to be a dialogical field in the Public Policies of the Ministry of Education and Science in Portugal. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

COVID-19 and pregnancy: A narrative review on the use of convalescent plasma

The emergence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic is a global concern, considering both the severity of the disease, with a high mortality rate compared to that of other influenza-like viral illnesses, and the lack of a specific, effective treatment. Pregnant women with coronavirus disease 2019 (COVID-19) represent a further challenge for clinicians. Indeed, although the majority of them are asymptomatic or their SARS-CoV-2 disease has a mild to moderate course, in some cases this viral infection is accompanied by severe respiratory symptoms. In such a critical clinical setting, the already limited therapeutic armamentarium available for COVID-19 patients is further restricted in pregnant women because of the risk of fetal toxicity especially during the first trimester of gestation. Among the treatment options, the use of convalescent plasma has gained increasing interest from investigators in pregnant women, given the initial positive reports on safety and efficacy aspects of this treatment in critically ill COVID-19 patients. However, the literature data are scanty and almost limited to single case reports, considering that pregnant women are usually excluded from trials on convalescent plasma. In this narrative review, we will critically discuss the current literature evidence on the use of hyperimmune plasma during pregnancies complicated by COVID-19.Copyright © 2021 AME Publishing Company.

Post-COVID-19 patients develop lung fibrotic-like changes: is there a role for IL-1alpha and TGF-beta?

Patients (around 40-50%) who were infected by SARS-CoV-2 develop a condition called as long-COVID-19 that lasted longer than the infection. One of the complications of post-COVID-19 (PC) is pulmonary fibrosis. T he purpose of this study was to identify blood biomarkers to predict PC patients undergoing pulmonary fibrosis. We analysed blood samples of healthy, anti-SARS-CoV-2 vaccinated subjects and PC patients, who were stratified according to the severity of the disease and chest computed tomography (CT) scan data that revealed fibrotic or non-fibrotic areas. PC patients had higher levels of the inflammatory C reactive protein (CRP), complement complex C5b-9, LDH, but not IL-6, independently of the severity of the disease and lung fibrotic areas. Interestingly, PC patients who presented signs of lung fibrosis were characterized by higher plasma levels of IL-1alpha, CXCL-10, TGF-beta, but not of IFN-beta, compared to healthy and vaccinated (VAX) subjects. In particular, 19 out of 23 (82.6%) severe PC and 8 out of 29 (27.6%) moderate PC patients presented signs of lung fibrosis, associated to lower levels of IFN-beta but higher IL-1alpha and TGF-beta. Instead, t he levels of IFN-beta were associated to the capability of the patient to respond to the infection without signs of lung fibrosis, implying a beneficial role of this cytokine. In conclusion, we found that higher plasma levels of IL-1alpha and TGF-beta, but not of IFN-beta, could predict an increased relative risk (RR=2.8) of lung fibrosislike changes in PC patients.

Real-world effectiveness of remdesivir for hospitalized patients with COVID-19: systematic review and metaanalysis

Introduction: Trials of remdesivir (RDV) for COVID-19 have provided evidence for regulatory approval. This is the first meta-analysis (MA) to evaluate the real-world effectiveness of RDV in patients hospitalized with COVID-19. Objective(s): To synthesize RDV observational data. Method(s): A systematic literature review identified observational studies of RDV. Outcomes were all-cause mortality and progression to invasive mechanical ventilation (IMV) assessed at early (day 14/15) and late (day 28/29/30) timepoints. MAs were conducted using standard random effects models;analyses were performed with R statistical software. Result(s): Of 1,069 studies identified, 29 met inclusion criteria for mortality data, 18 were excluded for low quality based on the ROBINS-I tool;11 studies from the United Kingdom, European Union, United States and Japan were included in the MA (N=166,399 patients). RDV was associated with a significant improvement in mortality at early (5 studies;risk ratio [RR] 0.71, 95% confidence interval [CI] 0.64-0.79) and late (10 studies, RR 0.82, 95%CI 0.71-0.95;Figure) timepoints. No significant effect was shown on the proportion of patients requiring IMV (evaluable only in the 3 studies denoted by asterisk in Figure, RR 1.07, 95%CI 0.84-1.34). Results were robust to scenario analyses. Conclusion(s): In a real-world setting, RDV is effective in reducing mortality in hospitalized COVID-19 patients.

Blockchain Assisted Voting in Academic Councils

Councils are a common organisational structure of Portuguese Universities and Polytechnic Institutes. They make the key decisions, in these organisations, by nominal voting at assembly meetings. The COVID pandemic forced the remote work upon most organisations, including universities and polytechnic institutes. Assuming that a remote assembly requires additional efforts in order to guarantee the integrity of the majority decisions taken by votes expressed by its members, opportunity arises for the use of a blockchain-assisted voting system. Benefits of blockchain, such as verifiability, immutability, tamper resistant, and its distributed nature appear to be a good fit. We propose a novel blockchain-assisted system to support the decision making of academic councils that operate by nominal voting in assemblies, gathering remotely and online. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Adoption of Telemedicine during the COVID-19 pandemic in Ibero-America: A Systematic Literature Review

The outbreak of COVID-19 caused a major international public health crisis and led to the imposition of social distancing measures to contain the spread of the virus. In this context, the use of telehealth skyrocketed as the only way to deliver healthcare to patients during a lockdown was remotely. The countries of Latin America and the Iberian Peninsula were severely hit by the pandemic and the prospects and challenges associated with widespread adoption of telehealth are unique. The goal of this systematic literature review is to explore how telehealth has been used during the pandemic to prevent, diagnose, treat and control diseases in Ibero-America. Thus, we sought to identify the main keywords, themes, theoretical frameworks and methodologies used by researchers in this area. We used several tools for bibliographic management like Rayyan, VOSViewer and NVIVO and followed the PRISMA protocol. Our analysis of themes showed the existence of 3 nodes within the literature: students, teachers and education. After searching in 6 databases, 1826 articles were found. After excluding the duplicates (231 articles), we screened and read the titles and s of 1595 articles. Only 119 articles met the inclusion criteria. Finally, after a full-text analysis, a final sample of 106 articles was selected for analysis. Spain and Brazil are the countries who have produced the greatest volume of research in the region. The public sector is the largest funder of research on this topic by far especially at national level. Our findings show that the research output in the region of Ibero-America (Latin America and Iberia) on this topic is still relatively small when compared to regions like North America.

Infectious disease screening outcomes and reducing barriers to care for unaccompanied asylum-seeking children: a single-centre retrospective clinical analysis

ObjectiveEvaluate the Unity Clinic's infectious disease screening programme for unaccompanied asylum-seeking children (UASC), calculate rates of infection and identify further health needs.DesignRetrospective audit of electronic patient data.Setting and patientsUASC who attended the Unity Clinic between 1 November 2019 and 22 March 2022.Main outcome measuresBaseline demographics, social, mental health and journey details, infection screening and investigation results.Results155 UASC were reviewed: 89% (138 of 155) male, median age 17 years (IQR 16-17). Most frequent countries of origin were Sudan, Eritrea and Afghanistan. Median duration of travel to the UK (n=79) was 2 years (IQR 0.5-4);35.6% (47 of 132) arrived by boat and 54.5% (72 of 132) by road. 44.8% (69 of 154) had one or more positive infection screening results: 22.7% (35 of 154) and 1.3% (2 of 154) positive for latent and active tuberculosis, respectively;4.6% (7 of 152) chronic active hepatitis B and 17.1% (26 of 152) for past infection;1.3% (2 of 154) for HIV;13.0% (19 of 146) for Strongyloides. There were three cases of syphilis (n=152;2.0%) and one chlamydia (n=148;0.7%)-none of whom disclosed prior sexual activity during screening. 39.6% (61 of 154) and 27.9% (43/154) reported disturbances to mood or sleep, respectively. 55.2% (85 of 154) disclosed traumatic incidents during and/or prior to their journey, including physical and sexual assault.ConclusionsThe Unity Clinic provides a thorough infectious disease screening service for UASC following national guidance. Results highlight the need for universal, non-judgemental screening for sexually transmitted infections, as targeted screening would not identify positive cases. High rates of well-being issues and previous abuse emphasise the need for multidisciplinary, collaborative approaches to care.

Trends in the parents' intention to vaccinate their children against COVID-19: A comparative study in Peru

Background. Although COVID-19 vaccination has shown to be clearly beneficial in children and adolescents to reduce hospitalization and potentially transmission, there is still a lot of hesitation among parents due to concerns about vaccine safety and efficacy, especially in children under 12 years of age. Methods. We conducted a comparative study in Peru to evaluate the trends in parents' intention to vaccinate their children under 12 years of age against COVID-19, for which an online survey was administered. The survey was distributed through social networks (Facebook, Twitter, etc.), and was applied during two periods: 11/25/2021 to 12/06/2022 (Period 1) and 01/16/2022 to 01/24/2022 (Period 2). We also assessed the factors associated with the intention to vaccinate in each period through crude (cPR) and adjusted prevalence rates (aPR). Results. During period 1, there were 673 participants (69.7% women). In period 2, we had 1139 respondents (77.7% women). Regarding intention to vaccinate, 83.5% of parents intended to vaccinate their children under 12 years of age during period 1. This percentage was almost the same during period 2 (83.3%). During period 1, the factors associated with a decrease in this intention were to believe that the vaccine was not necessary (aPR 0.65;95% CI 0.44 - 0.94, p=0.022), that it would not protect (aPR: 0.14;95% CI 0.03 - 0.63, p=0.011), that it would not be safe (aPR: 0.80;95% CI 0.70 - 0.92, p=0.001), that it could cause long-termside effects (aPR: 0.92;95% CI 0.85 - 1.00, p=0.037), and to think it should not be mandatory (aPR: 0.89;95% CI 0.80-0.99, p=0.038). During period 2, besides the factors identified in period 1, not knowing about COVID-19 infection risk in children (aPR: 0.92;95% CI 0.85-1.00, p=0.042) was also associated with a decrease in the intention. Living on the highlands or jungle was associated with an increase in the intention in both periods. Conclusion. A high rate of intention to vaccinate children under 12 years of age was noted among parents in Peru, which was maintained until the end of January of 2022, right before COVID-19 vaccination started for this age group. There was a perception in some parents that the vaccine might not be necessary or safe, leading to a lower intention to vaccinate their children.

Transfusoes De Hemocomponentes Por Internacao Hospitalar Na Rede Publica Municipal De Belo Horizonte Entre 2008 E 2021: Uma Analise De Serie Temporal

Resumo: Estudo retrospectivo longitudinal ecologico com dados referentes ao uso de hemocomponentes entre janeiro de 2008 e dezembro de 2021 na rede hospitalar do municipio de Belo Horizonte, Minas Gerais. Objetivos: Descrever as series mensais do numero de transfusoes de hemocomponentes e a taxa de transfusao por internacao em internacoes gerais na rede publica hospitalar sob a perspectiva da analise de series temporais. Metodos: A partir de dados do Sistema de Informacao Hospitalar do SUS (SIH-SUS), foram criadas seis series temporais de periodicidade mensal do numero de transfusoes de hemocomponentes e da taxa de transfusao por internacao. A estacionariedade, a tendencia e a sazonalidade das series foram verificadas pelo teste de raiz unitaria, pelo teste de Mann-Kendall e pelo teste de Fisher, respectivamente, utilizando-se os niveis de significancia de 10% para o primeiro teste e de 5% para os dois ultimos. Resultados: A taxa media mensal de uso de hemocomponentes por internacao hospitalar observada foi de 45,5%, 26,9% e 26,3% no Hospital Risoleta Tolentino Neves (HRN), Hospital Dr. Celio de Castro (HCC) e Hospital Odilon Behrens (HOB), respectivamente. A maior reducao do numero de transfusoes de hemocomponentes foi observada no HCC e a maior reducao da taxa de uso de hemocomponentes foi observada no HRN. O concentrado de hemacias foi o hemocomponente mais utilizado no HRN, HOB e HCC (54,6%, 58,3% e 65,4%, respectivamente). Todas as series apresentaram-se nao estacionarias, com tendencia de queda e presenca do componente sazonal com periodicidade de 12 meses. Todas as series apresentaram reducao da tendencia de queda durante o periodo critico da pandemia da COVID-19. Discussao: Os resultados encontrados neste estudo confirmam a hipotese inicial deste estudo de que o principal hemocomponente transfundido nos servicos de saude hospitalares publicos do municipio de Belo Horizonte sao os concentrados de hemacias. As taxas de transfusoes de hemocomponentes observadas nos tres hospitais sao semelhantes as taxas observadas em estudos nacionais e internacionais. A tendencia de queda na taxa de transfusoes de hemocomponentes por internacao hospitalar vai de encontro ao observado na literatura, que aponta para o aumento das taxas de transfusoes de hemocomponentes e dos resultados de um estudo semelhante realizado com uma rede de hospitais privados do mesmo municipio, no qual foi identificada a tendencia de alta em todos os hospitais analisados no estudo. A inexistencia dos dados sociodemograficos e informacoes sobre o local de utilizacao dos hemocomponentes podem ser considerados limitacoes do estudo. Conclusao: O estudo permitiu compreender o comportamento das series temporais relacionadas ao uso de hemocomponentes na rede publica hospitalar do municipio de Belo Horizonte. Acoes que envolvem a reducao da demanda por hemocomponentes, como, por exemplo, a implementacao de programas de Patient Blood Management, podem ser realizadas nos tres hospitais, com primazia para o HRN e para os concentrados de hemacias nos tres hospitais.

Risk factors for loneliness in family caregivers of people with dementia and enduring mental health conditions during the COVID-19 pandemic in Latin America

Background: During the COVID-19 pandemic, loneliness has increased in the general population due to government measures to contain the spread of the disease. In Latin America (LA), caregiving is most often delivered informally by family members Family caregivers often face mental health challenges linked to their caregiving role and their social context. Pandemic-related social restrictions have been especially detrimental for older people with dementia or other brain health challenges, as well as their family caregivers. We aimed to investigate the associations of loneliness, social isolation and care burden in these family caregivers. Method(s): We undertook a cross-sectional survey of over 300 informal caregivers of people with dementia or enduring mental health problems living in 4 Latin American countries, Mexico, Brazil, Chile, and Peru. We categorized loneliness into 3 groups 'low', 'moderate' and 'severe loneliness'. Here, we analyzed factors related to changes in the prevalence of moderate and severe loneliness before and during the pandemic using a longitudinal multinomial logistic regression model. Result(s): During the pandemic, there was a significant increase in loneliness prevalence (p<.001) among caregivers in Latin America, with more people having moderate (6.25% pre-pandemic;17.67% mid-pandemic) and severe loneliness (2.78% pre-pandemic;15.19% mid-pandemic). Gender differences in the prevalence of loneliness or higher levels of loneliness among dementia caregivers compared to caregivers of other conditions were not seen. The regression model revealed that the increment in risk for moderate loneliness during the pandemic was related to caregivers' age, level of education, and social contact/isolation. Increased risk for severe loneliness was related to caregivers' social contact during the pandemic and perceived mental health. Conclusion(s): Public health interventions regarding COVID-19 pandemic should consider increased loneliness in Latin-American caregivers. This population will need both, short and long-term mental health and practical support. Next steps include gathering more evidence on specific risk factors for loneliness and its impact on caregivers' physical and mental health. Copyright © 2022 the Alzheimer's Association.

Augmented Reality for a New Reality: Using UTAUT-3 to Assess the Adoption of Mobile Augmented Reality in Tourism (MART)

Few industries were more affected by the COVID-19 pandemic than tourism. One of Europe´s leading tourist destinations, Porto had undergone a major tourism boom until the start of pandemic. Mobile Augmented Reality (MAR) is one of the many emerging technologies that has great potential for tourist operators. Using this technology, they can create innovative tourism products that will help them recover from the present crisis. As a result, in this study, we will empirically test the latest version of the Unified Theory of Acceptance and Use of Technology (UTAUT) model to explore the factor leading to the adoption Mobile Augmented Reality in Tourism (MART) in Porto. In doing so, we aim to contribute to growing literature on the topic of Mobile Augmented Reality (MAR). The originality of this study lies in the use of an extended UTAUT model with greater predictive power and the exploration of the moderative role of gender, age and experience. To the data obtained from a random sample of 201 respondents who voluntarily answered an anonymous online questionnaire, we applied structural equational modeling and partial least squares (SEM-PLS) analysis to test the model. Our findings show that habit, hedonic motivations and facilitating conditions are the determinants of the use of MART. Copyright © 2022 by Author/s and Licensed by IADITI.

Knowledge management model applied to business financing after the economic crisis generated by the pandemic

In the face of the economic crisis in many productive sectors, generated by the COVID-19 virus pandemic, and being this understood as a “black swan-like” event, the need of to identify ways to reactivate the means of production was detected, in order to achieve the economic normality as soon as possible. To do this, it was decided to analyze models already implemented in organizations, which have shown great efficiency and which, due to their characteristics, can function as an aid to economic reactivation;or failing that, adapt a model to the economic reality of the current situation. For this, it was decided to make an analysis of models already presented in previous academic works, which have shown great efficiency and that due to their characteristics can function as an aid to economic recovery;or failing that, adapt one of the existing ones to the current economic reality. This research sought to reach the stage of formulating the Knowledge Management model that is most adapted to economic reality, and to evaluate its ease of implementation in companies, so that they can reactivate themselves financially and begin to give movement to the economy. from the knowledge generated in them. © 2022 Latin American and Caribbean Consortium of Engineering Institutions.
