Title A name given to the resource The olfactory nerve is not a likely route to brain infection in COVID-19: a critical review of data from humans and animal models. Creator An entity primarily responsible for making the resource Rafal Butowt, Nicolas Meunier, Bertrand Bryche, Christopher S von Bartheld Description An account of the resource One of the most frequent symptoms of COVID-19 is the loss of smell and taste. Based on the lack of expression of the virus entry proteins in olfactory receptor neurons, it was originally assumed that the new coronavirus (severe acute respiratory syndrome coronavirus 2, SARS-CoV-2) does not infect olfactory neurons. Recent studies have reported otherwise, opening the possibility that the virus can directly infect the brain by traveling along the olfactory nerve. Multiple animal models have been employed to assess mechanisms and routes of brain infection of SARS-CoV-2, often with conflicting results. We here review the current evidence for an olfactory route to brain infection and conclude that the case for infection of olfactory neurons is weak, based on animal and human studies. Consistent brain infection after SARS-CoV-2 inoculation in mouse models is only seen when the virus entry proteins are expressed abnormally, and the timeline and progression of rare neuro-invasion in these and in other animal models points to alternative routes to the brain, other than along the olfactory projections. COVID-19 patients can be assured that loss of smell does not necessarily mean that the SARS-CoV-2 virus has gained access to and has infected their brains.

Title A name given to the resource The Impact of Covid-19 Pandemic on Italian Nature-Based Programs in the Educational, Therapeutic, Training and Leisure Areas Creator An entity primarily responsible for making the resource Chiara Borelli, Alessandra Gigli, Giannino Melotti Description An account of the resource In these times of global crisis caused by Covid-19, there is an urgent need to address the topic of nature-based experiences in education: the pandemic has strongly highlighted both the interdependence between human beings and nature, and the need for mending the dichotomic vision that keeps them separate. Experiential education in natural contexts within an ecological framework might have a strategic role in this crucial period to develop anthropologic, civic, and dialogic conscience (Morin, 2001). Through this study, CEFEO Research Center had the objective of investigating the socio-economic impact of Covid-19 on Italian nature-based programs in the educational, therapeutic, training, and leisure areas. From 28 May to 19 June 2020, an online questionnaire was distributed with the purpose of understanding the socio-economic impact of the pandemic on nature-based programs during the lockdown period and during the period of first reopening, and the related needs and new opportunities for the future. The results highlight a paradox: the Covid-19 crisis has caused more problems for a sector which was already suffering from a lack of funding and of social and institutional acknowledgment. Many agencies working in the field lost months of income and numerous working days, and they are uncertain about the future: they are having difficulties surviving in a moment when we need them more.

Title A name given to the resource Incidence, risk factors, clinical characteristics and outcomes of deep venous thrombosis in patients with COVID-19 attending the Emergency Department: results of the UMC-19-S8. Creator An entity primarily responsible for making the resource Sònia Jiménez, Òscar Miró, Pere Llorens, Francisco J Martín-Sánchez, Guillermo Burillo-Putze, Pascual Piñera, Alfonso Martín, Aitor Alquézar, Eric J García-Lamberechts, Javier Jacob, María L L Grima, Javier Millán, Francisca Molina, Patricia B Albero, Carlos Cardozo, Josep M Mòdol, Alfons Aguirre, Ruth Gaya, María Adroher, Lluís Llauger, Juan J L Díaz, Nayra C González, Paula L Aragües, Ana P Gómez, Juan G Del Castillo Description An account of the resource A higher incidence of venous thromboembolism [both pulmonary embolism and deep vein thrombosis (DVT)] in patients with coronavirus disease 2019 (COVID-19) has been described. But little is known about the true frequency of DVT in patients who attend emergency department (ED) and are diagnosed with COVID-19. We investigated the incidence, risk factors, clinical characteristics and outcomes of DVT in patients with COVID-19 attending the ED before hospitalization. We retrospectively reviewed all COVID patients diagnosed with DVT in 62 Spanish EDs (20% of Spanish EDs, case group) during the first 2 months of the COVID-19 outbreak. We compared DVT-COVID-19 patients with COVID-19 without DVT patients (control group). Relative frequencies of DVT were estimated in COVID and non-COVID patients visiting the ED and annual standardized incidences were estimated for both populations. Sixty-three patient characteristics and four outcomes were compared between cases and controls. We identified 112 DVT in 74 814 patients with COVID-19 attending the ED [1.50‰; 95% confidence interval (CI), 1.23-1.80‰]. This relative frequency was similar than that observed in non-COVID patients [2109/1 388 879; 1.52‰; 95% CI, 1.45-1.69‰; odds ratio (OR) = 0.98 [0.82-1.19]. Standardized incidence of DVT was higher in COVID patients (98,38 versus 42,93/100,000/year; OR, 2.20; 95% CI, 2.03-2.38). In COVID patients, the clinical characteristics associated with a higher risk of presenting DVT were older age and having a history of venous thromboembolism, recent surgery/immobilization and hypertension; chest pain and desaturation at ED arrival and some analytical disturbances were also more frequently seen, d-dimer >5000 ng/mL being the strongest. After adjustment for age and sex, hospitalization, ICU admission and prolonged hospitalization were more frequent in cases than controls, whereas mortality was similar (OR, 1.37; 95% CI, 0.77-2.45). DVT was an unusual form of COVID presentation in COVID patients but was associated with a worse prognosis.

Title A name given to the resource Perceived impacts of the COVID-19 pandemic on cannabis-using emerging adults. Creator An entity primarily responsible for making the resource Erin E Bonar, Lyndsay Chapman, Jenna McAfee, Jason E Goldstick, José A Bauermeister, Patrick M Carter, Sean D Young, Maureen A Walton Description An account of the resource Cannabis-using youth are a large epidemiologic subgroup whose age and smoking-related risks underscore the importance of examining the impact of the COVID-19 pandemic in this population. Within a clinical trial (n = 36 received an intervention prior to data collection reported herein), we surveyed cannabis-using emerging adults (ages 18-25) about perceived COVID-19 impacts. Participants (n = 141) reporting weekly cannabis use (M = 18.6 use days in the past 30) were enrolled and completed online surveys as part of either their baseline or 3 month assessment. COVID-19-related measures included symptoms, substance use, mood, etc. Participants were 57% female (mean age = 21, standard deviation = 2.2), with 21% Hispanic/Latinx, 70% White, 20% Black/African American, and 10% of other races. Most participants (86%) reported quarantine/self-isolation (M = 59 days). Several had COVID-19 symptoms (16%), but none reported testing COVID-19 positive. Many respondents felt their cannabis use (35%-50%, across consumption methods) and negative emotions (e.g., loneliness, stress, and depression; 69.5%, 69.5%, and 61.8%, respectively) increased. They reported decreased in-person socialization (90.8%) and job losses (23.4%). Reports of increased cannabis smoking were associated with increased negative emotions. On an open-response item, employment/finances and social isolation were frequently named negative impacts (33.3% and 29.4%, respectively). Although cannabis-using emerging adults' reports of increases in cannabis use, coupled with mental health symptoms and social isolation, are concerning, the full impact of the pandemic on their health and well-being remains unknown. Future studies examining the relationship between social isolation, mental health, and cannabis use among young people are needed.

Title A name given to the resource ‘The long tail of Covid-19’ - The detection of a prolonged inflammatory response after a SARS-CoV-2 infection in asymptomatic and mildly affected patients [version 1; peer review: 2 approved] Creator An entity primarily responsible for making the resource Ivan Doykov, Jenny Hällqvist, Kimberly C. Gilmour, Louis Grandjean, Kevin Mills, Wendy E. Heywood Description An account of the resource ‘Long Covid’, or medical complications associated with post SARS-CoV-2 infection, is a significant post-viral complication that is being more and more commonly reported in patients. Therefore, there is an increasing need to understand the disease mechanisms, identify drug targets and inflammatory processes associated with a SARS-CoV-2 infection. To address this need, we created a targeted mass spectrometry based multiplexed panel of 96 immune response associated proteins. We applied the multiplex assay to a cohort of serum samples from asymptomatic and moderately affected patients. All patients had tested positive for a SARS-CoV-2 infection by PCR and were determined to be subsequently positive for antibodies. Even 40-60 days post-viral infection, we observed a significant remaining inflammatory response in all patients. Proteins that were still affected were associated with the anti-inflammatory response and mitochondrial stress. This indicates that biochemical and inflammatory pathways within the body can remain perturbed long after SARS-CoV-2 infections have subsided even in asymptomatic and moderately affected patients.

Title A name given to the resource New Urbanism: Past, Present, and Future Creator An entity primarily responsible for making the resource Ajay Garde Description An account of the resource The New Urbanism, initially conceived as an anti-sprawl reform movement, evolved into a new paradigm in urban design. Recently, however, some researchers have argued that the popular appeal of New Urbanism has eroded, the movement has lost its significance, and critical research on the broader theme has tapered off. In response, this article investigates whether the movement has lost its currency and explores the future of New Urbanism in the context of contemporary circumstances of development. The article begins with a brief description of the conceptualization of New Urbanism as an exception to the development trends of the time. Collaborative efforts of its protagonists that have contributed to the integration of New Urbanist concepts into other programs, policies, and development regulations are presented in the next section to describe its expansion, to clarify its mainstreaming, and to call attention to its broader impact. The concluding section presents contemporary circumstances of development and changes that are intensified by the COVID-19 pandemic, including those related to the nation’s demographics, climate change, technological advances, rapid growth of the digital economy, and acceleration of e-commerce to explore the significance of New Urbanism for future development.

Title A name given to the resource The Glasgow Prognostic Score and fibrinogen to albumin ratio as prognostic factors in hospitalized patients with COVID-19. Creator An entity primarily responsible for making the resource Mutlu Kuluöztürk, Figen Deveci, Teyfik Turgut, Önsel Öner Description An account of the resource Aim: This study aims to determine the prognostic value of the Glasgow Prognostic Score (GPS) and fibrinogen to albumin ratio (FAR) in patients with COVID-19.Methods: Electronic database records of 400 patients with COVID-19 were retrospectively analyzed and the initial levels of CRP, albumin, fibrinogen values were recorded. The ground-glass opacities (GGO) and consolidations were evaluated on thorax CT. Hospital mortality and the need for intensive care unit (ICU) transfer were determined as adverse outcomes.Results: It was determined that 345 patients (86.25%) were discharged while 31 patients (7.75%) were transferred to ICU in addition to 24 patients who died (6%). The rates of deaths and transfers to ICU were significantly increased in GPS 2 group compared to both GPS 0 and 1 groups. Additionally, increased FAR was observed in patients who died and transferred to ICU compared to the discharged patients. The FAR was significantly increased in patients with diffuse GGO. Logistic regression analysis indicated that FAR ≥144.59 and the presence of GPS 2 were independent predictors of the adverse outcomes in COVID-19 patients.Conclusion: Our results demonstrated that the GPS and FAR could possess a predictive value for adverse outcomes in patients with COVID-19.

In this study, we investigate the potential of high-dose intravenous vitamin C (HDIVC) in the prevention of moderate COVID-19 disease aggravation.Methods: In this retrospective before-after case-matched clinical study, we compare the outcome and clinical courses of patients with moderate COVID-19 patients who were treated with an HDIVC protocol (intravenous injection of vitamin C, 100 mg/kg/day, 1 g/h, for 7 days from admission) during a one-month period (between March 18 and april 18, 2020, HDIVC group) with a control group treated without the HDIVC protocol during the preceding two months (January 18 to March 18, 2020). Patients in the two groups were matched in a 1:1 ratio according to age and gender.Results: The HDIVC and control groups each comprised 55 patients. For the primary outcomes, there was a significant difference in the number of patients that evolved from moderate to severe type between the two groups (HDIVC: 4/55 vs. control: 12/55, relative risk [RR] = 0.28 [0.08, 0.93], P = 0.03). Compared to the control group, there was a shorter duration of systemic inflammatory response syndrome (SIRS) (P = 0.0004) during the first week and lower SIRS occurrence (2/21 vs 10/22, P = 0.0086) on Day 7 (6–7 days after admission). In addition, HDIVC group had lower C-reactive protein levels (P = 0.005) and higher number of CD4+ T cells from Day 0 (on admission) to Day 7 (P = 0.04).” The levels of coagulation indicators, including activated partial thromboplastin time and D-dimer were also improved in the HDIVC compared to the control group on Day 7.Conclusion: HDIVC may be beneficial in limiting disease aggravation in the early stage of COVID-19 pneumonia, which may be related to its improvements on the inflammatory response, immune function and coagulation function. Further randomized controlled trials are required to augment these findings.

Title A name given to the resource A Person-to-Person and Person-to-Place COVID-19 Contact Tracing System Based on OGC IndoorGML Creator An entity primarily responsible for making the resource Sara Saeedi, Soroush Ojagh, Steve H. L. Liang Description An account of the resource With the wide availability of low-cost proximity sensors, a large body of research focuses on digital person-to-person contact tracing applications that use proximity sensors. In most contact tracing applications, the impact of SARS-CoV-2 spread through touching contaminated surfaces in enclosed places is overlooked. This study is focused on tracing human contact within indoor places using the open OGC IndoorGML standard. This paper proposes a graph-based data model that considers the semantics of indoor locations, time, and users’ contexts in a hierarchical structure. The functionality of the proposed data model is evaluated for a COVID-19 contact tracing application with scalable system architecture. Indoor trajectory preprocessing is enabled by spatial topology to detect and remove semantically invalid real-world trajectory points. Results show that 91.18% percent of semantically invalid indoor trajectory data points are filtered out. Moreover, indoor trajectory data analysis is innovatively empowered by semantic user contexts (e.g., disinfecting activities) extracted from user profiles. In an enhanced contact tracing scenario, considering the disinfecting activities and sequential order of visiting common places outperformed contact tracing results by filtering out unnecessary potential contacts by 44.98 percent. However, the average execution time of person-to-place contact tracing is increased by 58.3%.
