82. Cabbage and fermented vegetables : from death rate heterogeneity in countries to candidates for mitigation strategies of severe COVID-19Jean Bousquet, Josep M. Antò i Boquè, Wienczyslawa Czarlewski, Tari Haahtela, Susana C. Fonseca, Guido Laccarino, Hubert Blain, Alain Vidal, Aziz Sheikh, Cezmi A. Akdis, Torsten Zuberbier, Samo Kreft, Klemen Jenko, Maja Jošt, Peter Kopač, Mitja Košnik, Karmen Kramer Vrščaj, Bojan Madjar, Davor Plavec, Tanja Soklič, Jure Urbančič, Mihaela Zidarn, 2020, izvirni znanstveni članek Povzetek: Large differences in COVID-19 death rates exist between countries and between regions of the same country. Some very low death rate countries such as Eastern Asia, Central Europe or the Balkans have a common feature of eating large quantities of fermented foods. Although biases exist when examining ecological studies, fermented vegetables or cabbage were associated with low death rates in European countries. SARS-CoV-2 binds to its receptor, the angiotensin converting enzyme 2 (ACE2). As a result of SARS-Cov-2 binding, ACE2 downregulation enhances the angiotensin II receptor type 1 (AT1R) axis associated with oxidative stress. This leads to insulin resistanceas well as lung and endothelial damage, two severe outcomes of COVID-19. The nuclear factor (erythroid-derived 2)-like 2 (Nrf2) is the most potent antioxidant in humans and can block the AT1R axis. Cabbage contains precursors of sulforaphane, the most active natural activator of Nrf2. Fermented vegetables contain many lactobacilli, which are also potent Nrf2 activators. Three examples are given: Kimchi in Korea, westernized foods and the slum paradox. It is proposed that fermented cabbage is a proof-of-concept of dietary manipulations that may enhance Nrf2-associated antioxidant effects helpful in mitigating COVID-19 severity.

83. Pulmonary pathology and COVID-19 : lessons from autopsy : the experience of European pulmonary pathologistsFiorella Calabrese, Federica Pezzuto, Francesco Fortarezza, Paul Hofman, Izidor Kern, Angel Panizo, Jan von der Thüsen, Sergei Timofeev, Gregor Gorkiewicz, Francesca Lunardi, 2020, izvirni znanstveni članek Povzetek: Since its initial recognition in December 2019, Coronavirus disease 19 (COVID-19) has quickly spread to a pandemic
infectious disease. The causative agent has been recognized as a novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), primarily affecting the respiratory tract. To date, no vaccines are available nor any specific treatment. To limit the number of infections, strict directives have been issued by governments that have been translated into equally rigorous guidelines notably for post-mortem examinations by international and national scientific societies. The recommendations for biosafety control required during specimen collection and handling have strongly limited the practice of autopsies of the COVID-19 patients to a few adequate laboratories. A full pathological examination has always been considered an important tool to better understand the pathophysiology of diseases, especially when the knowledge of an emerging disorder is limited and the impact on the healthcare system is significant. The first evidence of diffuse alveolar damage in the context of an acute respiratory distress syndrome has now been joined by the latest findings that report a more complex scenario in COVID-19, including a vascular involvement and a wide spectrum of associated pathologies. Ancillary tools such as electron microscopy and molecular biology used on autoptic tissue samples from autopsy are also significantly contributing to confirm and/or identify new aspects useful for a deeper knowledge of the pathogenetic mechanisms. This article will review and summarize the pathological findings described in COVID-19 until now, chiefly focusing on the respiratory tract, highlighting the importance of autopsy towards a better knowledge of this disease.
