ABSTRACT
Given that the financial markets are facing the effects of the coronavirus pandemic, we chose to perform an analysis on them, in order to see the transmission of volatility, the effects of the contagion and the interconnection between the financial markets. Using stock indices from different countries and applying theoretical and empirical methods such as univariate and multivariate models (ARCH–GARCH, BEKK), we aim to capture volatility and bidirectional contagion, as well as testing and occurring the phenomenon of clustering volatility and its transmission effect. © 2022, Bucharest University of Economic Studies.

ABSTRACT
Coronavirus disease 2019 (COVID-19) could emerge not only as viral pneumonia but also as a cardiovascular disease. Thromboprophylaxis has been recommended by the current guidelines, especially COVID-19 patients who are hospitalized. On the other hand, these drugs might cause serious bleeding complications. Hereby, we aimed to report three cases with spontaneous rectus sheath hematoma (RSH) developed after being administered thromboprophylaxis for severe COVID-19 pneumonia. In this case series, we draw attention to the rare, but mortal complication of the COVID-19 thromboprophylaxis regimen.
