UniversitĂ€re Notaufnahmen in der Coronapandemie â Ergebnisse des ReCovERRegisters / University emergency departments in the corona pandemicâResults from the ReCovER registry
Background: The current COVID-19 pandemic, despite the availability of rapid tests and the start of the vaccination campaign, continues to pose major challenges to emergency departments (ED). Structured collection of demographic, clinical, as well as treatment-related data provides the basis for establishing evidence-based processes and treatment concepts.
Aim of the work: To present the systematic collection of clinical parameters in patients with suspected COVID-19 in the Registry for COVID-19 in the Emergency Room (ReCovER) and descriptive presentation of the first 1000 patients.
Materials and methods: Data from patients with suspected COVID-19, regardless of evidence of SARS-CoVâ2 infection, are continuously entered into a web-based, anonymized registry in ED at six university hospitals.
Results: Between 19 May 2020 and 13 January 2021, 1000 patients were entered into the registry, of whom 594 patients (59.4%) were in the SARS-CoVâ2 positive group (PG) and 406 patients (40.6%) were in the negative group (NG). Patients of the PG had significantly fewer pre-existing conditions and a significantly longer latency between symptom onset and presentation to the ED (median 5 vs. 3 days), were more likely to suffer from cough, myalgia, fatigue, and loss of smell/taste and had significantly higher oxygen requirements than NG patients. The rate of severe disease progression was significantly higher in the PG, and persistent symptoms were more common after discharge (11.1 vs. 4.6%).
Conclusions: The multicenter collection of comprehensive clinical data on COVID-19 suspected cases in the ED allows analysis of aspects specific to the situation in Germany in particular. This is essential for a targeted review and adaptation of internationally published strategies

Social Movements and International Relations: A Relational Framework
Social movements are increasingly recognized as significant features of contemporary world politics, yet to date their treatment in international relations theory has tended to obfuscate the considerable diversity of these social formations, and the variegated interactions they may establish with state actors and different structures of world order. Highlighting the difficulties conventional liberal and critical approaches have in transcending conceptions of movements as moral entities, the article draws from two under-exploited literatures in the study of social movements in international relations, the English School and Social Systems Theory, to specify a wider range of analytical interactions between different categories of social movements and of world political structures. Moreover, by casting social movement phenomena as communications, the article opens international relations to consideration of the increasingly diverse trajectories and second-order effects produced by social movements as they interact with states, intergovernmental institutions, and transnational actors
Multiple Scenario Generation of Subsurface Models:Consistent Integration of Information from Geophysical and Geological Data throuh Combination of Probabilistic Inverse Problem Theory and Geostatistics
Neutrinos with energies above 1017 eV are detectable with the Surface Detector Array of the Pierre Auger Observatory. The identification is efficiently performed for neutrinos of all flavors interacting in the atmosphere at large zenith angles, as well as for Earth-skimming \u3c4 neutrinos with nearly tangential trajectories relative to the Earth. No neutrino candidates were found in 3c 14.7 years of data taken up to 31 August 2018. This leads to restrictive upper bounds on their flux.

Comparison of left double lumen tube and y-shaped and double-ended bronchial blocker for one lung ventilation in thoracic surgery - a randomised controlled clinical trial
Background: Double lumen tube (DLT) intubation is the most commonly used technique for one lung ventilation.
Bronchial blockers (BB) are an alternative, especially for difficult airways. The EZ-bronchial blocker (EZB) is an innovative
y-shaped and double-ended device of the BB family.
Methods: A randomised, controlled trial was conducted in 80 patients undergoing elective thoracic surgery using
DLT or EZB for one lung ventilation (German Clinical Trial Register DRKS00014816). The objective of the study was to
compare the clinical performance of EZB with DLT. Primary endpoint was total time to obtain successful one lung
ventilation. Secondary endpoints were time subsections, quality of lung collapse, difficulty of intubation, any complications
during the procedure, incidence of objective trauma of the oropharynx and supraglottic space and intubation-
related subjective symptoms.
Results: 74 patients were included, DLT group (n = 38), EZB group (n = 36). Median total time to obtain one lung
ventilation [IQR] in the DLT group was 234 s [207 to 294] versus 298 s [243 to 369] in the EZB group (P = 0.007). Median
total time was relevantly influenced by different preparation times. Quality of lung collapse was equal in both groups,
DLT group 89.5% were excellent vs. 83.3% in the EZB group (P = 0.444). Inadequate lung collapse in five patients of
the EZB group resulted in unsuccessful repositioning attempts and secondary DLT placement. Endoscopic examinations
revealed significantly more carina trauma (P = 0.047) and subglottic haemorrhage (P = 0.047) in the DLT group.
Postoperative subjective symptoms (sore throat, hoarseness) were more common in the DLT group, as were speech
problems.
Conclusions: Using EZB prima facie results in prolonged time to obtain one lung ventilation with equal quality of
lung collapse for the thoracic surgeon. If preparation times are omitted in the analysis, the time difference is statistically
and clinically not relevant. Our data showed only little evidence for reducing objective airway trauma as well
as subjective complaints. In summary both procedures were comparable in terms of times and clinical applicability.
Therefore decisions for DLT or EZB should depend more on individual experience, in-house equipment and the individual
patient, than on any times that are neither clinically significant nor relevant
