To understand resilience on its aggregate level it is important to identify (non)resilient actions of individual actors who comprise regions. As the retail sector among others represents an important factor in an urban regions recovery, we focus on the resilience of (textile) retailers within the city of W{\"u}rzburg in Germany to the COVID-19 pandemic. To address the identified research gap, this paper applies the concept of resilience. Firstly, conducting expert interviews, the individual (textile) retailers' level and their strategies in coping with the crisis is considered. Secondly, conducting a contextual analysis of the German city of W{\"u}rzburg, we wish to contribute to the discussion of how the resilience of a region is influenced inter alia by actors. Our study finds three main strategies on the individual level, with retailers: (1) intending to "bounce back" to a pre-crisis state, (2) reorganising existing practices, as well as (3) closing stores and winding up business. As at the time of research, no conclusions regarding long-term impacts and resilience are possible, the results are limited. Nevertheless, detailed analysis of retailers' strategies contributes to a better understanding of regional resilience.}, language = {en} } @article{BartmannFischerHuebneretal.2021, author = {Bartmann, Catharina and Fischer, Leah-Maria and H{\"u}bner, Theresa and M{\"u}ller-Reiter, Max and W{\"o}ckel, Achim and McNeill, Rhiannon V. and Schlaiss, Tanja and Kittel-Schneider, Sarah and K{\"a}mmerer, Ulrike and Diessner, Joachim}, title = {The effects of the COVID-19 pandemic on psychological stress in breast cancer patients}, series = {BMC Cancer}, volume = {21}, journal = {BMC Cancer}, doi = {10.1186/s12885-021-09012-y}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-265802}, year = {2021}, abstract = {Background: The majority of breast cancer patients are severely psychologically affected by breast cancer diagnosis and subsequent therapeutic procedures. The COVID-19 pandemic and associated restrictions on public life have additionally caused significant psychological distress for much of the population. It is therefore plausible that breast cancer patients might be particularly susceptible to the additional psychological stress caused by the pandemic, increasing suffering. In this study we therefore aimed to assess the level of psychological distress currently experienced by a defined group of breast cancer patients in our breast cancer centre, compared to distress levels preCOVID-19 pandemic. Methods: Female breast cancer patients of all ages receiving either adjuvant, neoadjuvant, or palliative therapies were recruited for the study. All patients were screened for current or previous COVID-19 infection. The participants completed a self-designed COVID-19 pandemic questionnaire, the Stress and Coping Inventory (SCI), the National Comprehensive Cancer Network (R) (NCCN (R)) Distress Thermometer (DT), the European Organization for Research and Treatment of Cancer (EORTC) QLQ C30, and the BR23. Results: Eighty-two breast cancer patients were included. Therapy status and social demographic factors did not have a significant effect on the distress caused by the COVID-19 pandemic. The results of the DT pre and during COVID-19 pandemic did not differ significantly. Using the self-designed COVID-19 pandemic questionnaire, we detected three distinct subgroups demonstrating different levels of concerns in relation to SARS-CoV-2. The subgroup with the highest levels of concern reported significantly decreased life quality, related parameters and symptoms. Conclusions: This monocentric study demonstrated that the COVID-19 pandemic significantly affected psychological health in a subpopulation of breast cancer patients. The application of a self-created "COVID-19 pandemic questionnaire"could potentially be used to help identify breast cancer patients who are susceptible to increased psychological distress due to the COVID-19 pandemic, and therefore may need additional intensive psychological support.}, language = {en} } @article{BleilevensSoppertHoffmannetal.2021, author = {Bleilevens, Christian and Soppert, Josefin and Hoffmann, Adrian and Breuer, Thomas and Bernhagen, J{\"u}rgen and Martin, Lukas and Stiehler, Lara and Marx, Gernot and Dreher, Michael and Stoppe, Christian and Simon, Tim-Philipp}, title = {Macrophage migration inhibitory factor (MIF) plasma concentration in critically ill COVID-19 patients: a prospective observational study}, series = {Diagnostics}, volume = {11}, journal = {Diagnostics}, number = {2}, issn = {2075-4418}, doi = {10.3390/diagnostics11020332}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-228967}, year = {2021}, abstract = {Mortality in critically ill coronavirus disease 2019 (COVID-19) patients is high and pharmacological treatment strategies remain limited. Early-stage predictive biomarkers are needed to identify patients with a high risk of severe clinical courses and to stratify treatment strategies. Macrophage migration inhibitory factor (MIF) was previously described as a potential predictor for the outcome of critically ill patients and for acute respiratory distress syndrome (ARDS), a hallmark of severe COVID-19 disease. This prospective observational study evaluates the predictive potential of MIF for the clinical outcome after severe COVID-19 infection. Plasma MIF concentrations were measured in 36 mechanically ventilated COVID-19 patients over three days after intensive care unit (ICU) admission. Increased compared to decreased MIF was significantly associated with aggravated organ function and a significantly lower 28-day survival (sequential organ failure assessment (SOFA) score; 8.2 ± 4.5 to 14.3 ± 3, p = 0.009 vs. 8.9 ± 1.9 to 12 ± 2, p = 0.296; survival: 56\% vs. 93\%; p = 0.003). Arterial hypertension was the predominant comorbidity in 85\% of patients with increasing MIF concentrations (vs. decreasing MIF: 39\%; p = 0.015). Without reaching significance, more patients with decreasing MIF were able to improve their ARDS status (p = 0.142). The identified association between an early MIF response, aggravation of organ function and 28-day survival may open future perspectives for biomarker-based diagnostic approaches for ICU management of COVID-19 patients.}, language = {en} } @article{DoelkenStichSpinner2021, author = {D{\"o}lken, Lars and Stich, August and Spinner, Christoph D.}, title = {Remdesivir for Early COVID-19 Treatment of High-Risk Individuals Prior to or at Early Disease Onset — Lessons Learned}, series = {Viruses}, volume = {13}, journal = {Viruses}, number = {6}, issn = {1999-4915}, doi = {10.3390/v13060963}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-239648}, year = {2021}, abstract = {After more than one year of the COVID-19 pandemic, antiviral treatment options against SARS-CoV-2 are still severely limited.

Here, we highlight and discuss the key findings of these studies and underlying reasons for their failure. We elaborate on how such shortcomings should be prevented in future clinical trials and pandemics. We suggest in conclusion that any novel antiviral agent that enters human trials should first be tested in a post-exposure setting to provide rapid and solid evidence for its clinical efficacy before initiating further time-consuming and costly clinical trials for more advanced disease.

Consequently, elective and semi-urgent operations on the increasing number of patients severely affected by COVID-19 have been indefinitely postponed.in many countries with unclear implications on disease progression and overall survival. The purpose of this study was to evaluate whether the establishment of a standardized screening program for acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is sufficient to ensure high-quality medical and surgical treatment of COVID-19 and non-COVID-19 patients while minimizing in-hospital SARS-CoV-2 transmission. Methods The screening program comprised polymerase chain reaction (PCR) testing of nasopharyngeal swabs and a standardized questionnaire about potential symptoms for SARS-CoV-2 infection. All elective and emergency patients admitted to the surgical department of a tertiary-care hospital center in Lower Franconia, Germany, between March and May 2020 were included and their characteristics were recorded. Results Out of the study population (n = 657), 509 patients (77.5\%) had at least one risk factor for a potentially severe course of COVID-19 and 164 patients (25\%) were active smokers. The average 7-day incidence in Lower Franconia was 24.0/100,000 during the observation period. Preoperative PCR testing revealed four asymptomatic positive patients out of the 657 tested patients. No postoperative SARS-CoV-2 infection or transmission could be detected. Conclusion The implementation of a standardized preoperative screening program to both COVID-19 and non-COVID-19 patients can ensure high-quality surgical care while minimizing infection risk for healthcare workers and potential in-hospital transmission.}, language = {en} } @article{GesslerLehmannBoeseletal.2021, author = {Gessler, Florian and Lehmann, Felix and B{\"o}sel, Julian and Fuhrer, Hannah and Neugebauer, Hermann and Wartenberg, Katja E. and Wolf, Stefan and Bernstock, Joshua D. and Niesen, Wolf-Dirk and Schuss, Patrick}, title = {Triage and Allocation of Neurocritical Care Resources During the COVID 19 Pandemic - A National Survey}, series = {Frontiers in Neurology}, volume = {11}, journal = {Frontiers in Neurology}, issn = {1664-2295}, doi = {10.3389/fneur.2020.609227}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-221593}, year = {2021}, abstract = {Objective: In light of the ongoing COVID-19 pandemic and the associated hospitalization of an overwhelming number of ventilator-dependent patients, medical and/or ethical patient triage paradigms have become essential. While guidelines on the allocation of scarce resources do exist, such work within the subdisciplines of intensive care (e.g., neurocritical care) remains limited. Methods: A 16-item questionnaire was developed that sought to explore/quantify the expert opinions of German neurointensivists with regard to triage decisions. The anonymous survey was conducted via a web-based platform and in total, 96 members of the Initiative of German Neurointensive Trial Engagement (IGNITE)-study group were contacted via e-mail. The IGNITE consortium consists of an interdisciplinary panel of specialists with expertise in neuro-critical care (i.e., anesthetists, neurologists and neurosurgeons). Results: Fifty members of the IGNITE consortium responded to the questionnaire; in total the respondents were in charge of more than 500 Neuro ICU beds throughout Germany. Common determinants reported which affected triage decisions included known patient wishes (98\%), the state of health before admission (96\%), SOFA-score (85\%) and patient age (69\%). Interestingly, other principles of allocation, such as a treatment of "youngest first" (61\%) and members of the healthcare sector (50\%) were also noted. While these were the most accepted parameters affecting the triage of patients, a "first-come, first-served" principle appeared to be more accepted than a lottery for the allocation of ICU beds which contradicts much of what has been reported within the literature. The respondents also felt that at least one neurointensivist should serve on any interdisciplinary triage team. Conclusions: The data gathered in the context of this survey reveal the estimation/perception of triage algorithms among neurointensive care specialists facing COVID-19. Further, it is apparent that German neurointensivists strongly feel that they should be involved in any triage decisions at an institutional level given the unique resources needed to treat patients within the Neuro ICU.}, language = {en} } @article{GuptaSrivastavaMinochaetal.2021, author = {Gupta, Shishir K. and Srivastava, Mugdha and Minocha, Rashmi and Akash, Aman and Dangwal, Seema and Dandekar, Thomas}, title = {Alveolar regeneration in COVID-19 patients: a network perspective}, series = {International Journal of Molecular Sciences}, volume = {22}, journal = {International Journal of Molecular Sciences}, number = {20}, issn = {1422-0067}, doi = {10.3390/ijms222011279}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-284307}, year = {2021}, abstract = {A viral infection involves entry and replication of viral nucleic acid in a host organism, subsequently leading to biochemical and structural alterations in the host cell.

In contrast, social cognitive models propose that safety behaviors are predicted by a different set of variables that mainly reflect cognitive and socio-structural aspects. Here, we directly tested these opposing hypotheses in young adults (N = 4134) in the context of COVID-19-related safety behaviors to prevent infections. In each participant, we collected measures of negative affect as well as cognitive and socio-structural variables during the lockdown in the first infection wave in Germany. We found a negative effect of the pandemic on emotional responses. However, this was not the main predictor for young adults' willingness to comply with COVID-19-related safety measures. Instead, individual differences in compliance were mainly predicted by cognitive and socio-structural variables. These results were confirmed in an independent data set. This study shows that individuals scoring high on negative affect during the pandemic are not necessarily more likely to comply with safety regulations. Instead, political measures should focus on cognitive interventions and the societal relevance of the health issue.

However, specific diagnostic or therapeutic algorithms for CAC have not been established. In the current study, we analyzed coagulation abnormalities with point-of-care testing (POCT) and their relation to hemostatic complications in patients suffering from COVID-19 induced Acute Respiratory Distress Syndrome (ARDS). Our hypothesis was that specific diagnostic patterns can be identified in patients with COVID-19 induced ARDS at risk of thromboembolic complications utilizing POCT. Methods This is a single-center, retrospective observational study. Longitudinal data from 247 rotational thromboelastometries (Rotem®) and 165 impedance aggregometries (Multiplate®) were analysed in 18 patients consecutively admitted to the ICU with a COVID-19 induced ARDS between March 12th to June 30th, 2020. Results Median age was 61 years (IQR: 51-69). Median PaO2/FiO2 on admission was 122 mmHg (IQR: 87-189), indicating moderate to severe ARDS. Any form of hemostatic complication occurred in 78 \% of the patients with deep vein/arm thrombosis in 39 \%, pulmonary embolism in 22 \%, and major bleeding in 17 \%. In Rotem® elevated A10 and maximum clot firmness (MCF) indicated higher clot strength. The delta between EXTEM A10 minus FIBTEM A10 (ΔA10) > 30 mm, depicting the sole platelet-part of clot firmness, was associated with a higher risk of thromboembolic events (OD: 3.7; 95 \%CI 1.3-10.3; p = 0.02). Multiplate® aggregometry showed hypoactive platelet function. There was no correlation between single Rotem® and Multiplate® parameters at intensive care unit (ICU) admission and thromboembolic or bleeding complications. Conclusions Rotem® and Multiplate® results indicate hypercoagulability and hypoactive platelet dysfunction in COVID-19 induced ARDS but were all in all poorly related to hemostatic complications..}, language = {en} }
