Is triple-positive serology for Epstein-Barr virus (VCA-IgG, VCA-IgM, EBNA-IgG) a specific feature of angioimmunoblastic T-cell lymphoma?
Purpose: We assessed the frequency of triple-positive serology (viral capsid antigen [VCA]-immunoglobulin G [IgG], VCA-immunoglobulin M, Epstein-Barr nuclear antigen-IgG) for Epstein-Barr virus (EBV) in a small number of patients with angioimmunoblastic T-cell lymphoma (AITL) at disease onset. Methods: Nine patients with newly diagnosed AITL were retrospectively enrolled in the present study. For all of them, EBV serology data were available. Results: Of 9 patients, 7 (77.7%) had a triple-positive serology (VCA-IgG, VCA-IgM, EBNA-IgG ) for EBV. These patients were characterized by bone marrow involvement, high incidence of thrombocytopenia, and poor prognosis according to Revised International Prognostic Index and Prognostic Index for Angioimmunoblastic T-cell Lymphoma scores. Conclusion: Assessment of both viremia and serology for EBV could be useful in patients with clinical and laboratory data suggesting lymphoma diagnosis; furthermore, although our data need to be validated in a larger cohort of patients, triple positivity for EBV serology might help to direct the diagnosis toward AITL

Nationality in international investment arbitration
Nationality in international investment arbitration Abstract The subject of this rigorous thesis is the nationality in international investment arbitration. The objective of this thesis is to provide the insight into the issue of nationality in international investment disputes to the professional community and to introduce significant investment disputes regarding this topic. The paper is divided into six main parts. First chapter describes the international investment arbitration (dispute) in general. Second chapter is devoted to the definition of investor and to various principles that can be used to assess the nationality of investors. Third chapter looks at the nationality of investors from the perspective of Washington Treaty, whereas fourth chapter looks at the nationality from the perspective of Energy Charter Treaty. Fifth chapter introduces some significant bilateral investment treaties signed by Czech Republic and their approaches for defining the nationality of investors. Finally six chapter looks at some particular issues through case studies of arbitration tribunals' decisions.StátnĂ pĹ™Ăslušnost v mezinárodnĂch investiÄŤnĂch sporech Abstrakt PĹ™edmÄ›tem tĂ©to rigorĂłznĂ práce je státnĂ pĹ™Ăslušnost v mezinárodnĂch investiÄŤnĂch sporech.

Role of mesenchymal stromal cell-derived extracellular vesicles in tumour microenvironment
Abstract Stromal cells, deriving from mesenchymal stromal cells (MSCs), are crucial component of tumour microenvironment and represent key regulators of tumour processes. MSCs can be recruited to the tumour environment and interact with many cellular elements, thus influencing tumour biology. Cell-to-cell communication is in part mediated by the release of extracellular vesicle (EVs). EVs can induce significant molecular changes in recipient cells, delivering bioactive molecules. In this review, we describe the MSC-derived EVs content and discuss their role in different processes related to cancer biology. Furthermore, we summarize chemical or biological EVs modifications aiming to develop more efficient antitumor therapies
Immunological characterization of multipotent mesenchymal stromal cells--The International Society for Cellular Therapy (ISCT) working proposal.
Disclosure of interests: The authors have no commercial, proprietary, or financial interest in the products or companies described in this article.International audienceCultured mesenchymal stromal cells (MSCs) possess immune regulatory properties and are already used for clinical purposes, although preclinical data (both in vitro and in vivo in animal models) are not always homogeneous and unequivocal. However, the various MSC-based clinical approaches to treat immunological diseases would be significantly validated and strengthened by using standardized immune assays aimed at obtaining shared, reproducible and consistent data. Thus, the MSC Committee of the International Society for Cellular Therapy has decided to put forward for general discussion a working proposal for a standardized approach based on a critical view of literature data
The Evolving Knowledge on T and NK Cells in Classic Hodgkin Lymphoma: Insights into Novel Subsets Populating the Immune Microenvironment
Classic Hodgkin lymphoma (cHL) is a unique lymphoid neoplasm characterized by extensive immune infiltrates surrounding rare malignant Hodgkin Reed-Sternberg (HRS) cells. Different subsets of T and NK cells have long been recognized in the cHL microenvironment, yet their distinct contribution to disease pathogenesis has remained enigmatic. Very recently, novel platforms for high dimensional analysis of immune cells, such as single-cell RNA sequencing and mass cytometry, have revealed unanticipated insights into the composition of T- and NK-cell compartments in cHL. Advances in imaging techniques have better defined specific T-helper subpopulations physically interacting with neoplastic cells. In addition, the identification of novel cytotoxic subsets with an exhausted phenotype, typically enriched in cHL milieu, is shedding light on previously unrecognized immune evasion mechanisms. This review examines the immunological features and the functional properties of T and NK subsets recently identified in the cHL microenvironment, highlighting their pathological interplay with HRS cells. We also discuss how this knowledge can be exploited to predict response to immunotherapy and to design novel strategies to improve PD-1 blockade efficacy
Management of Chronic Myeloid Leukemia in Advanced Phase
Management of chronic myeloid leukemia (CML) in advanced phases remains a challenge also in the era of tyrosine kinase inhibitors (TKIs) treatment. Cytogenetic clonal evolution and development of resistant mutations represent crucial events that limit the benefit of subsequent therapies in these patients. CML is diagnosed in accelerated (AP) or blast phase (BP) in <5% of patients, and the availability of effective treatments for chronic phase (CP) has dramatically reduced progressions on therapy. Due to smaller number of patients, few randomized studies are available in this setting and evidences are limited. Nevertheless, three main scenarios may be drawn: (a) patients diagnosed in AP are at higher risk of failure as compared to CP patients, but if they achieve optimal responses with frontline TKI treatment their outcome may be similarly favorable; (b) patients diagnosed in BP may be treated with TKI alone or with TKI together with conventional chemotherapy regimens, and subsequent transplant decisions should rely on kinetics of response and individual transplant risk; (c) patients in CP progressing under TKI treatment represent the most challenging population and they should be treated with alternative TKI according to the mutational profile, optional chemotherapy in BP patients, and transplant should be considered in suitable cases after return to second CP. Due to lack of validated and reliable markers to predict blast crisis and the still unsatisfactory results of treatments in this setting, prevention of progression by careful selection of frontline treatment in CP and early treatment intensification in non-optimal responders remains the main goal. Personalized evaluation of response kinetics could help in identifying patients at risk for progression
