ABSTRACT
BACKGROUND: In the past two decades, three coronavirus epidemics have been reported. Coronavirus disease 2019 (COVID-19) is caused by a severe acute respiratory syndrome (SARS)-like coronavirus (SARS-CoV-2). In most patients, the disease is characterized by interstitial pneumonia, but features can affect other organs. PURPOSE: To document the radiological features of the patients and to perform a narrative review of the literature. MATERIAL AND METHODS: We conducted a retrospective, single-center study on 1060 consecutive hospitalized patients with COVID-19 at our institution. According to the inclusion criteria, we selected patients to be studied in more radiological detail. All images were obtained as per standard of care protocols. We performed a statistic analysis to describe radiological features. We then presented a systematic review of the main and conventional neuroimaging findings in COVID-19. RESULTS: Of 1060 patients hospitalized for COVID-19 disease, 15% (159) met the eligibility criteria. Of these, 16 (10%) did not undergo radiological examinations for various reasons, while 143 (90%) were examined. Of these 143 patients, 48 (33.6%) had positive neuroimaging. We found that the most frequent pathology was acute ischemic stroke (n=16, 33.3%). Much less frequent were Guillain-Barre syndrome (n=9, 18.8%), cerebral venous thrombosis (n=7, 14.6%), encephalitis or myelitis (n=6, 12.5%), intracranial hemorrhage and posterior hemorrhagic encephalopathy syndrome (n=4, 8.3%), exacerbation of multiple sclerosis (n=4, 8.3%), and Miller-Fisher syndrome (n=2, 4.2%). CONCLUSION: Our data are coherent with the published literature. Knowledge of these patterns will make clinicians consider COVID-19 infection when unexplained neurological findings are encountered.
ABSTRACT
In each stage of the Covid-19 pandemic, we have witnessed initiatives that, through digital technologies, have attempted to ensure the presence of theatre and to nurture the relationship with audiences. Our research asks which entry barriers to the artistic field have been strengthened or weakened by implementing theatre initiatives for online audiences and how these initiatives have affected the regional performing arts scene. The study consists of three parts. In the first part, analysis of Italian calls for digital performance projects was carried out to investigate the institutional construction of beneficiaries and imagined audiences. In the second part, we analysed the case of the digital-theatre season MPA - Marche Palcoscenico Aperto. The MPA project provided funding for artists from the Marche region in Italy to realize online performances between February and May 2021. Eleven focus groups were conducted with 41 of the 60 participating companies. In the third phase, four in-depth interviews were conducted with the project's organisers. Findings show how the increased dependence of theatre artists on the artistic system imposed by Covid has simultaneously produced an increase in the collective awareness of the artistic class, but also a stronger distinction between professionalism and amateurism.
