Wie mit Populisten umgehen? Demokratie- und planungstheoretische Perspektiven für Planungspraxis und Planungsforschung

Das Erstarken populistischer Kräfte stellt die räumliche Planung vor neue Herausforderungen, weil daraus sowohl inhaltliche als auch verfahrensbezogene Konflikte entstehen können. Ziel des Beitrags ist es, drei demokratie- und planungstheoretisch begründete Perspektiven auf Populismus und Planung zu entwickeln und Schlussfolgerungen für Planungspraxis und Planungsforschung zu ziehen. Dabei handelt es sich um elitenorientierte, rational-technokratische Theorien, um deliberative, beteiligungsorientierte Theorien sowie um radikaldemokratisch-agonistische Theorien. Übersetzt man diese theoretischen Perspektiven in planerische Grundorientierungen, dann ergibt sich ein differenzierter Blick auf fünf mögliche Optionen zum Umgang mit populistischen Akteuren und Tendenzen in der Planungspraxis: "ignorieren", "argumentieren", "integrieren", "exkludieren" und "profitieren". So könnten Planer und Populisten unter bestimmten Annahmen zu Verbündeten werden, die beispielsweise das Interesse an der Re-Politisierung bestehender Zustände teilen. Und schließlich werden aus den verschiedenen theoretischen Blickwinkeln heraus Themen und Fragen für weitergehende Untersuchungen vorgeschlagen.The rise of populist forces presents a new challenge to spatial planning because of its potential for conflict in substantial and procedural terms. The aim of the article is to develop three perspectives on populism and planning based on democracy and planning theory and to draw conclusions for planning practice and planning research. The theories consulted are elitist, rational-technocratic theories, deliberative, participatory theories as well as radical democratic-agonistic theories. If we are to translate theses perspectives into planners' hypothetical courses of actions, a nuanced picture of possible strategies of action in dealing with populist actors and tendencies comes about. Planning practitioners may choose strategies like "ignoring", "arguing", "integrating", "excluding" and "profiting from" populists. As such, planners and populists might become allies sharing a common interest in re-politicizing current conditions. Concluding, with said theoretical perspectives in mind, the contribution offers topics and questions for further research

ECMO for COVID-19 patients in Europe and Israel

Since March 15th, 2020, 177 centres from Europe and Israel have joined the study, routinely reporting on the ECMO support they provide to COVID-19 patients. The mean annual number of cases treated with ECMO in the participating centres before the pandemic (2019) was 55. The number of COVID-19 patients has increased rapidly each week reaching 1531 treated patients as of September 14th. The greatest number of cases has been reported from France (n = 385), UK (n = 193), Germany (n = 176), Spain (n = 166), and Italy (n = 136) .The mean age of treated patients was 52.6 years (range 16–80), 79% were male. The ECMO configuration used was VV in 91% of cases, VA in 5% and other in 4%. The mean PaO2 before ECMO implantation was 65 mmHg. The mean duration of ECMO support thus far has been 18 days and the mean ICU length of stay of these patients was 33 days. As of the 14th September, overall 841 patients have been weaned from ECMO support, 601 died during ECMO support, 71 died after withdrawal of ECMO, 79 are still receiving ECMO support and for 10 patients status n.a. . Our preliminary data suggest that patients placed on ECMO with severe refractory respiratory or cardiac failure secondary to COVID-19 have a reasonable (55%) chance of survival. Further extensive data analysis is expected to provide invaluable information on the demographics, severity of illness, indications and different ECMO management strategies in these patients

Racial differences in systemic sclerosis disease presentation: a European Scleroderma Trials and Research group study

Objectives. Racial factors play a significant role in SSc. We evaluated differences in SSc presentations between white patients (WP), Asian patients (AP) and black patients (BP) and analysed the effects of geographical locations.Methods. SSc characteristics of patients from the EUSTAR cohort were cross-sectionally compared across racial groups using survival and multiple logistic regression analyses.Results. The study included 9162 WP, 341 AP and 181 BP. AP developed the first non-RP feature faster than WP but slower than BP. AP were less frequently anti-centromere (ACA; odds ratio (OR) = 0.4, P < 0.001) and more frequently anti-topoisomerase-I autoantibodies (ATA) positive (OR = 1.2, P = 0.068), while BP were less likely to be ACA and ATA positive than were WP [OR(ACA) = 0.3, P < 0.001; OR(ATA) = 0.5, P = 0.020]. AP had less often (OR = 0.7, P = 0.06) and BP more often (OR = 2.7, P < 0.001) diffuse skin involvement than had WP.AP and BP were more likely to have pulmonary hypertension [OR(AP) = 2.6, P < 0.001; OR(BP) = 2.7, P = 0.03 vs WP] and a reduced forced vital capacity [OR(AP) = 2.5, P < 0.001; OR(BP) = 2.4, P < 0.004] than were WP. AP more often had an impaired diffusing capacity of the lung than had BP and WP [OR(AP vs BP) = 1.9, P = 0.038; OR(AP vs WP) = 2.4, P < 0.001]. After RP onset, AP and BP had a higher hazard to die than had WP [hazard ratio (HR) (AP) = 1.6, P = 0.011; HR(BP) = 2.1, P < 0.001].Conclusion. Compared with WP, and mostly independent of geographical location, AP have a faster and earlier disease onset with high prevalences of ATA, pulmonary hypertension and forced vital capacity impairment and higher mortality. BP had the fastest disease onset, a high prevalence of diffuse skin involvement and nominally the highest mortality

Allosteric and orthosteric sites in CC chemokine receptor (CCR5), a chimeric receptor approach

Chemokine receptors play a major role in immune system regulation and have consequently been targets for drug development leading to the discovery of several small molecule antagonists. Given the large size and predominantly extracellular receptor interaction of endogenous chemokines, small molecules often act more deeply in an allosteric mode. However, opposed to the well described molecular interaction of allosteric modulators in class C 7-transmembrane helix (7TM) receptors, the interaction in class A, to which the chemokine receptors belong, is more sparsely described. Using the CCR5 chemokine receptor as a model system, we studied the molecular interaction and conformational interchange required for proper action of various orthosteric chemokines and allosteric small molecules, including the well known CCR5 antagonists TAK-779, SCH-C, and aplaviroc, and four novel CCR5 ago-allosteric molecules. A chimera was successfully constructed between CCR5 and the closely related CCR2 by transferring all extracellular regions of CCR2 to CCR5, i.e. a Trojan horse that resembles CCR2 extracellularly but signals through a CCR5 transmembrane unit. The chimera bound CCR2 (CCL2 and CCL7), but not CCR5 chemokines (CCL3 and CCL5), with CCR2-like high affinities and potencies throughout the CCR5 signaling unit. Concomitantly, high affinity binding of small molecule CCR5 agonists and antagonists was retained in the transmembrane region. Importantly, whereas the agonistic and antagonistic properties were preserved, the allosteric enhancement of chemokine binding was disrupted. In summary, the Trojan horse chimera revealed that orthosteric and allosteric sites could be structurally separated and still act together with transmission of agonism and antagonism across the different receptor units
