TL;DR: A case and systematic review of myoclonus and cerebellar ataxia associated with COVID-19 is presented in this paper, where the authors identify 51 cases associated with the coronavirus disease 2019 pandemic.
Abstract: Since the beginning of the coronavirus disease 2019 (COVID-19) pandemic in December 2019, neurological manifestations have been recognized as potential complications. Relatively rare movement disorders associated with COVID-19 are increasingly reported in case reports or case series. Here, we present a case and systematic review of myoclonus and cerebellar ataxia associated with COVID-19. A systematic review was performed according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guideline using the PubMed and Ovid MEDLINE databases, from November 1, 2019 to December 6, 2020. 51 cases of myoclonus or ataxia associated with COVID-19, including our case, were identified from 32 publications. The mean age was 59.6 years, ranging from 26 to 88 years, and 21.6% were female. Myoclonus was multifocal or generalized and had an acute onset, usually within 1 month of COVID-19 symptoms. Myoclonus occurred in isolation (46.7%), or with ataxia (40.0%) or cognitive changes (30.0%). Most cases improved within 2 months, and treatment included anti-epileptic medications or immunotherapy. Ataxia had an acute onset, usually within 1 month of COVID-19 symptoms, but could be an initial symptom. Concurrent neurological symptoms included cognitive changes (45.5%), myoclonus (36.4%), or a Miller Fisher syndrome variant (21.2%). Most cases improved within 2 months, either spontaneously or with immunotherapy. This systematic review highlights myoclonus and ataxia as rare and treatable post-infectious or para-infectious, immune-mediated phenomena associated with COVID-19. The natural history is unknown and future investigation is needed to further characterize these movement disorders and COVID-19.

TL;DR: In this article, the effects of Instagram influencers and their branded-UGC on consumer behavior outcomes were investigated. But the authors focused on the dynamics of interaction among brand-related user-generated contents (UGC) posted on Instagram, social media-based brand communication with Instagram celebrities (parasocial interaction [PSI] and envy), and consumers' characteristics (social comparison tendency, compulsive buying tendency, and materialistic envy).

TL;DR: Panic buying has re-emerged as a new normal consumer behaviour and has become a coping mechanism for real and perceived dangers associated with COVID-19 Despite the need for a better understanding of the panic buying phenomenon, there has been a lack of scholarly research on this topic as mentioned in this paper.
Abstract: Panic buying has re-emerged as a ‘new’ normal consumer behaviour and has become a coping mechanism for real and perceived dangers associated with COVID-19 Despite the need for a better understanding of the panic buying phenomenon, there has been a lack of scholarly research on this topic This study seeks to fill this gap In this article, we systematically review extant studies in panic buying from the last two decades We analyse and categorize them according to Callahan's 4W (2014) review structure and Paul and Rosado-Serrano's (2019) TCCM framework We found that the existing publications in panic buying are fragmented across multiple disciplines Due to the nature of the panic-induced behaviour, most of them have been written as a reaction to the pandemic crisis We contribute to marketing research by providing theoretical, contextual and methodological insights into the field of panic buying Furthermore, we develop a research agenda related to retailer and consumer perspectives Additionally, we identify research issues related to policymaking and governance, as well as broader societal impacts that need to be addressed in the future © 2021 The Authors International Journal of Consumer Studies published by John Wiley & Sons Ltd
