Pulmonary embolism severity and in-hospital mortality: An international comparative study between COVID-19 and non-COVID patients.

OBJECTIVE: To compare the severity of pulmonary embolism (PE) between patients with and without COVID, and to assess the association between severity and in-hospital-mortality. METHODS: We performed an analysis of 549 COVID (71.3% PCR-confirmed) and 439 non-COVID patients with PE consecutively included by 62 Spanish and 16 French emergency departments. PE-severity was assessed by size, the presence of right ventricular dysfunction (RVD), and the sPESI. The association of PE-severity and in-hospital-mortality was assessed both in COVID and non-COVID patients, and the interaction of COVID status and PE severity/outcome associations was also evaluated. RESULTS: COVID patients had PEs of smaller size (43% vs 56% lobar or larger, 42% vs. 35% segmental and 13% vs. 9% subsegmental, respectively; p = 0.01 for trend), less RVD (22% vs. 16%, p =0.02) and lower sPESI (p =0.03 for trend). Risk of in-hospital death was higher in COVID patients (12.8% vs. 5.3%, p < 0.001). PE-severity assessed by RVD and sPESI was independently associated with in-hospital-mortality in COVID patients, while PE size and sPESI were significantly associated with in-hospital-mortality in non-COVID. COVID status showed a significant interaction in the association of PE size and outcome (p =0.01), with OR for in-hospital mortality in COVID and non-COVID patients with lobar or larger PE of 0.92 (95%CI=0.19-4.47) and 4.47 (95%CI=1.60-12.5), respectively. Sensitivity analyses using only PCR-confirmed COVID cases confirmed these results. CONCLUSION: COVID patients present a differential clinical picture, with PE of less severity than in non-COVID patients. An increased sPESI was associated with the risk of mortality in both groups but, PE size did not seem to be associated with in-hospital mortality in COVID patients.

The Figure of the Teacher-Prosumer for the Development of an Innovative, Sustainable, and Committed Education in Times of COVID-19

Studies on the adaptation from face-to-face to online teaching during lockdown show the before and after in education that faces the double challenge of promoting digital skills and public access to connectivity and electronic devices in the post-COVID-19 era. Therefore, this article contributes to these new emerging lines of educational research by presenting an educational innovation project called “Teachers Versus COVID-19”. This project aimed to verify whether the figure of teacher-prosumer, that is, consumers of media culture and creators of their own educational resources, favors the initial training of teachers during the pandemic. To this end, the following objectives were proposed: firstly, test whether the figure of the teacher-prosumer contributes to improving the adaptation of face-to-face teaching to the virtual modality of the Didactics of Social Sciences in the Degree in Primary Education during lockdown;secondly, analyze the production of content on social networks by the students in the Degree in Primary Education, according to the objectives of sustainable development. To validate our teacher-prosumer proposal, we chose the design-based research (DBR) qualitative methodology. For this, 240 students from the course in Didactics of Social Sciences of the Degree in Primary Education at the University of Malaga created 37 educational videos that teach the social sciences curriculum to children between 6 and 12 years of age from the perspective of relevant social problems and the Sustainable Development Goals. These videos were disseminated through the project’s YouTube channel. The results of this study corroborate the effectiveness of turning students into teachers-prosumers, generating the development of critical, creative, digital, and socio-emotional skills so that they feel committed to playing an active role in social changes for a sustainable world.
