The 10-year anniversary of intense protest in Greece and the role of Facebook

This study provides a comparative analysis of collective meaning-making processes by unpacking activists' discourses (within and in relation to their polis) and online (on Facebook) during the financial, post-financial, and COVID-19 crises in Greece (2011–2021). By analyzing 71 semi-structured interviews with activists and 14,475 Facebook posts, we first evaluate actors' identity progression, then identify the differences and commonalities between activists' discourses attached to their collectivity, by investigating the role of Facebook therein. Our findings indicate that activists' efforts to delimitate their identity, primarily around the detachment of citizens from their polis, paved the way for the (re)invention of the meaning-making practices of each collectivity. Thus, the formation of an overarching identity of the citizen as an activist-subject unites subjects over power struggles, despite their political differences. [ FROM AUTHOR]

Pulmonary Embolism in Post-CoviD-19 Patients, a Literature Review: Red Flag for Increased Awareness?

Although COVID-19 was primarily considered a respiratory illness, rapidly accumulating data suggest that COVID-19 is associated with a high incidence of venous thromboembolic complications. The primary objective of this review article was to reveal whether we need to increase awareness of pulmonary embolism in the period following the COVID-19 infection given that the epidemiologic facts are still poor. A literature search and a critical review of the collected studies were conducted. An electronic search of PubMed, Science Direct Scopus, Google Scholar, and Excerpta Medica Database (EMBASE) from June 2020 until June 2022. The long-term health consequences of COVID-19 remain largely unclear. This review highlights the importance of awareness of the potentially increased incidence of venous thromboembolism in post-COVID-19 patients, even those with mild or asymptomatic disease. Further research is required to establish appropriate clinical management guidelines for the prevention of thromboembolic complications in the post-COVID-19 period.

Conspiratorial Narratives on Facebook and Their Historical Contextual Associations: A Case Study from Cyprus

Conspiracy theories and their effects have greatly proliferated during the COVID-19 pandemic crisis. As in various countries, so in Cyprus, a mobilization of anti-vaxxers organized mainly through Facebook, violently attacked the largest media group of the island, ?Sigma?. Taking into consideration local peculiarities and historical contexts, a qualitative research was conducted on comments posted on Sigma Live's Facebook page, spanning between August 2020 and June 2021.The article illustrates how cultural, political, and historical peculiarities are instrumental in the formation of anti-vax movements, and how conspiracy theorizing in general is inextricably bound to such peculiarities. We demonstrate how new publics in social media platforms may dispute media outlets? representations through using the official channels of these outlets, highlighting an understudied facet of participatory media. The paper advocates for more context-bound theoretical analyses of conspiracy theorizing, which delve deeper into the meaning-making, interpretative, and discursive practices of conspiracists against media outlets.

Hemophagocytic lymphohistiocytosis diagnosed by bone marrow trephine biopsy in living post-COVID-19 patients: case report and mini-review.

Hemophagocytic lymphohistiocytosis (HLH) constitutes a life-threatening inflammatory syndrome. Postmortem histological findings of bone marrow (BM) from COVID-19 patients showed histiocytosis and hemophagocytosis and supported the hypothesis that secondary HLH (sHLH) may be triggered by SARS-CoV-2 infection. However, there are a limited number of sHLH cases in which trephine has been performed in living post-COVID-19 patients. Here we present a recent case and a mini-review of sHLH diagnosed by trephine biopsy in living patients after COVID-19. An 81-year-old man with a past medical history of hypertension, diabetes, ischemic stroke, was referred to the hospital to evaluate leukocytosis, pyuria, and elevation of inflammatory markers four weeks after recovering from COVID-19. Computed tomography of the abdomen did not reveal focal signs of infection or hepatosplenomegaly. The patient received intravenous meropenem and two packed red blood cell units. Leukocytes and C-reactive protein were gradually decreased. A BM biopsy was performed and the patient was discharged on cefixime. BM smear revealed severe anemia, lymphopenia, and dysplastic morphologic findings of erythroblasts, neutrophils, and megakaryocytes. Trephine biopsy revealed hypercellular marrow dyserythropoiesis, plasmacytosis, lymphocytosis, histiocytosis, hemophagocytosis, and the absence of granulomas or carcinoma. Immunohistochemistry documented a mixed population of T lymphocytes (CD3+) and B lymphocytes (CD20+). Strong positivity for CD68 confirmed histiocytosis. CD138 κ, λ staining proved polyclonal plasmacytosis. Perl's staining showed excess hemosiderin deposits. Based on our findings, we document sHLH in trephine BM biopsy of a living post-COVID-19 patient and persistent leukocytosis, underscoring the diagnostic value of trephine biopsy in preventing life-threatening conditions such as COVID-19.

Promyelocytic Leukemia Antigen Expression: a Histological Marker for Primary Biliary Cholangitis Diagnosis?

BACKGROUND AND OBJECTIVES: Distinguishing primary biliary cholangitis (PBC) from other cholestatic diseases at the histological level could be assisted by new methods, such as immunohistochemical staining of specific antigens. METHODS: We evaluated whether the detection of promyelocytic leukemia protein (PML) can serve as a specific and sensitive marker for PBC diagnosis. Liver biopsies from 26 PBC patients, 20 primary sclerosing cholangitis (PSC), 37 viral hepatitis, 11 non-alcoholic steatohepatitis (NASH) and 5 normal patients were investigated after immunostaining with the anti-PML monoclonal PG-M3, IgG1 antibody. RESULTS: Immunoreactivity in bile ducts was expressed by the PML-score (quotient of positive ducts to the total number of portal tracts multiplied by 2). PML-score was higher in PBC as compared to controls (P < 0.001). Using a cutoff of 0.18, PML-score proved highly sensitive (84.6%) and specific (89.7%) for confirming PBC as compared to only 5% of PSC, 9.1% of NASH and 13.5% of viral hepatitis patients (P < 0.001). Irrespective of the underlying disease, patients with PML-score > 0.18 were older (P = 0.007), more often females (P < 0.001) with higher ALP (P < 0.001), γ-GT (P = 0.001) and IgM (P < 0.001) compared to the patients with PML-score < 0.18. CONCLUSIONS: We postulate that a simple PML immunohistochemical test could be sufficient for histopathological discrimination of PBC in problematic cases of undefined cholestatic disorders, including small-duct PSC and AMA-negative PBC cases.
