ABSTRACT
In this paper, we study the short-run evolution of political trust during the recent covid-19 pandemic using survey data for a sample of young individuals living in Germany, France, Italy, and Spain. In particular, we analyze whether pre-pandemic perceptions and experiences of citizens about various dimensions of local governments and institutional quality had any mediating effect on the evolution of political trust after the outbreak of the covid-19 pandemic. The results show a relative increase in political trust of about 9% in regions with high institutional quality (75th percentile) compared with regions with low institutional quality (25th percentile) over the period 2019-2020. This divergence can be associated with either a better performance of policymakers in high-quality institutions regions, or to more positive attitudes toward politicians by citizens that, before the pandemic, believed to live in regions with efficient institutions. Overall results are not affected by the inclusion of regional fixed effects or by possible differential evolution of political trust according to a large set of observable regional characteristics.
ABSTRACT
OBJECTIVE: The purpose of this study is to evaluate chest CT imaging features, clinical characteristics, laboratory values of COVID-19 patients who underwent CTA for suspected pulmonary embolism. We also examined whether clinical, laboratory or radiological characteristics could be associated with a higher rate of PE. MATERIALS AND METHODS: This retrospective study included 84 consecutive patients with laboratory-confirmed SARS-CoV-2 who underwent CTA for suspected PE. The presence and localization of PE as well as the type and extent of pulmonary opacities on chest CT exams were examined and correlated with the information on comorbidities and laboratory values for all patients. RESULTS: Of the 84 patients, pulmonary embolism was discovered in 24 patients. We observed that 87% of PE was found to be in lung parenchyma affected by COVID-19 pneumonia. Compared with no-PE patients, PE patients showed an overall greater lung involvement by consolidation (p = 0.02) and GGO (p < 0.01) and a higher level of D-Dimer (p < 0,01). Moreover, the PE group showed a lower level of saturation (p = 0,01) and required more hospitalization (p < 0,01). CONCLUSION: Our study showed a high incidence of PE in COVID-19 pneumonia. In 87% of patients, PE was found in lung parenchyma affected by COVID-19 pneumonia with a worse CT severity score and a greater number of lung lobar involvement compared with non-PE patients. CT severity, lower level of saturation, and a rise in D-dimer levels could be an indication for a CTPA. ADVANCES IN KNOWLEDGE: Certain findings of non-contrast chest CT could be an indication for a CTPA.
