In this paper, we present a corpus for heritage Bosnian/Croatian/Montenegrin/Serbian (BCMS) spoken in German-speaking Switzerland. The corpus consists of elicited conversations between 29 ...second-generation speakers originating from different regions of former Yugoslavia. In total, the corpus contains 30 turn-aligned transcripts with an average length of 6 min. It is enriched with extensive speakers’ metadata, annotations, and pre-calculated corpus counts. The corpus can be accessed through an interactive corpus platform that allows for browsing, querying, and filtering, but also for creating and sharing custom annotations. Principal user groups we address with this corpus are researchers of heritage BCMS, as well as students and teachers of BCMS living in diaspora. In addition to introducing the corpus platform and the workflows we adopted to create it, we also present a case study on BCMS spoken by a pair of siblings who participated in the map task, and discuss advantages and challenges of using this corpus platform for linguistic research.

In this paper, we present an overview of freely available web applications providing online access to spoken language corpora. We explore and discuss various solutions with which the corpus providers ...and corpus platform developers address the needs of researchers who are working with spoken language. The paper aims to contribute to the long-overdue exchange and discussion of methods and best practices in the design of online access to spoken language corpora.
Introduction
Peripheral blood stem cell (PBSC) harvesting requires reliable and safe vascular access. In our institution, a change of practice was implemented and the central venous catheter (CVC) ...placement for all autologous PBSC collections was abandoned in favor of a careful evaluation of peripheral venous access (PVA) for each individual patient. The aim of this prospective study was to evaluate the rate of patients with adequate peripheral veins for autologous PBSC collection and compare patient characteristics, collection efficacy, and complication rate between patients with PVA and CVC.
Method
Peripheral veins were assessed by the apheresis nurse team in all patients referred between January 2020 and July 2021 to autologous PBSC collection. Only in case of difficult venous access, CVC was inserted. Large volume leukapheresis (LVL) procedures, which processed ≥3 total blood volumes, were performed.
Results
In 65 (57%) patients PVA was used, while 49 (43%) patients required placement of short‐term CVC. Peripheral venous access was successfully used significantly more often in males (69.8%) (P = 0.010), and patients with multiple myeloma (71.0%) than in patients with non‐Hodgkin's lymphoma (35.9%) and Hodgkin's lymphoma patients (33.3%) (P < 0.001). There was a significant difference in the type of prior administered chemotherapy; in the patients who received cytostatics free chemotherapy, PVA was used more often (75.0%) (P = 0.007). In terms of the efficacy and safety of LVLs, there were no differences between procedures performed using PVA and CVCs.
Conclusion
Peripheral venous access is feasible for autologous PBSC collection in more than a half of patients, in particular in those with multiple myeloma. Changes in the treatment of multiple myeloma, using new proteasome inhibitors‐based and immunomodulatory agents that do not adversely affect peripheral veins, have enabled the use of PVA even at the high blood flow rates required by LVL. Peripheral venous access is not associated with safety issues or with a lesser collection efficiency, and it is cost‐effective as well. Each patient referred to autologous PBSC collection needs to be evaluated individually by the experienced apheresis team for the most appropriate venous access.

Gastrointestinal angiodysplasia (GIA) is the most common
digestive tract vascular malformation, often causing recurrent
gastrointestinal bleeding. Despite association with certain
hereditary diseases ...1,2,3, most GIAs are acquired, associated
with aortic stenosis, hemodialysis, malignancies, or liver
cirrhosis or idiopathic, and they appear among the elderly (>60
years) 4. Advances in endoscopy brought about management
improvements, but due to numerous lesions disseminated over
the digestive tract, treatment of GIA remains a clinical challenge.
Novel studies suggested that the use of thalidomide might be
beneficial in these patients due to its antiangiogenic properties
5,6. Thalidomide and its modern analogues currently represent
a backbone treatment of another disease: multiple myeloma
(MM) 7. Here we would like to present a case of successful MM
and GIA treatment with thalidomide.

Patients with lymphoproliferative diseases (LPD) are vulnerable to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Here, we describe and analyze the outcome of 366 adult ...patients with chronic lymphocytic leukemia (CLL) or non-Hodgkin Lymphoma (NHL) treated with targeted drugs and laboratory-confirmed COVID-19 diagnosed between February 2020 and January 2022. Median follow-up was 70.5 days (IQR 0-609). Most used targeted drugs were Bruton-kinase inhibitors (BKIs) (N= 201, 55%), anti-CD20 other than rituximab (N=61, 16%), BCL2 inhibitors (N=33, 9%) and lenalidomide (N=28, 8%).Only 16.2% of the patients were vaccinated with 2 or more doses of vaccine at the onset of COVID-19. Mortality was 24% (89/366) on day 30 and 36%(134/366) on the last day of follow-up. Age >75 years (p<0.001, HR 1.036), active malignancy (p<0.001, HR 2.215), severe COVID-19 (p=0.017, HR 2.270) and admission to ICU (p<0.001, HR 5.751) were risk factors for mortality at last day of follow up. There was no difference in OS rates in NHL vs CLL patients (p=0.306), nor in patients treated with or without BKIs (p=0.151). Mortality in ICU was 66% (CLL 61%, NHL 76%). Overall mortality rate decreased according to vaccination status, being 39% in unvaccinated patients, 32% and 26% in those having received one or two doses, respectively, and 20% in patients with a booster dose (p=0.245). Overall mortality rate dropped from 41% during the first semester of 2020 to 25% at the last semester of 2021. These results show increased severity and mortality from COVID-19 in LPDs patients treated with targeted drugs.
Daratumumab je prvo monoklonsko protutijelo anti-CD38 koje se primjenjuje u liječenju multiplog mijeloma. Njegova primjena uzrokuje panreaktivnost u testovima prijetransfuzijskog ispitivanja. ...Panreaktivnost je posljedica vezanja monoklonskog protutijela anti-CD38 na protein CD38 na površini eritrocita, što u standardnom testiranju onemogućuje otkrivanje antieritrocitnih aloprotutijela i osiguranje podudarne krvi za transfuzijsko liječenje. Cilj rada bila je retrospektivna analiza vlastitih iskustava u rješavanju smetnja prijetransfuzijskog ispitivanja uzrokovanih monoklonskim protutijelom anti-CD38 i u transfuzijskom liječenju tih bolesnika. Prikazani su postupci za prijetransfuzijsko ispitivanje i transfuzijsko liječenje bolesnika liječenih monoklonskim protutijelom anti-CD38 koji su provedeni u Kliničkome bolničkom centru Zagreb. U istraživanju je analizirano 10-ero bolesnika liječenih daratumumabom. Prije i poslije primjene daratumumaba pretražena su antieritrocitna protutijela i određen je direktan antiglobulinski test. Pri transfuzijskom liječenju napravljeni su test pretraživanja antieritrocitnih protutijela i križne reakcije standardnim testiranjem i specifičnim postupcima imunohematoloških ispitivanja za uklanjanje smetnja monoklonskog protutijela anti-CD38. Postupci su uključivali obradu eritrocita ditiotreitolom koncentracije 0,2 M i neutralizacijski test uz primjenu reagensa DaraEx. Kod svih bolesnika testovi pretraživanja antieritrocitnih protutijela i križne reakcije bili su nakon primjene daratumumaba pozitivni, dok je direktan antiglobulinski test zbog primjene daratumumaba bio pozitivan u gotovo polovine bolesnika. Nakon obrade eritrocita ditiotreitolom 0,2 M učestalost lažno pozitivnih rezultata testova pretraživanja antieritrocitnih protutijela i križnih reakcija iznosila je oko 40%, a poslije primjene reagensa DaraEx oko 20%. Oba specifična postupka, obrada eritrocita ditiotreitolom 0,2 M i neutralizacijski test primjenom reagensa DaraEx, nisu se pokazala dovoljno pouzdanima u rješavanju smetnja uzrokovanih monoklonskim protutijelom anti-CD38. Zato je za transfuzijsko liječenje tih bolesnika nužno osigurati eritrocitne pripravke podudarne prema klinički najvažnijim antigenima u sustavima krvnih grupa Rh, Kell, Kidd, Duffy i MNS. Dobra suradnja između odjela i transfuzijske službe te postojanje protokola za prijetransfuzijsko ispitivanje i transfuzijsko liječenje ostaju preduvjet za pravodobno i sigurno transfuzijsko liječenje te skupine bolesnika.
Acute myeloid leukemia (AML) is a malignant hematopoietic disease with poor clinical course and outcome. There is a constant need for new prognostic factors that could facilitate patient risk ...stratification. The aim of our research was to determine the phosphorylation levels of phosphatidylinositol 3-kinase (PI3K)/Akt and mitogen-activated protein kinase (MAPK) pathways in leukemic cells, their relation to P-glycoprotein (P-gp) expression/activity and their prognostic significance in adult de novo AML. A total of 118 patients with AML were enrolled in the study. In a multivariate Cox regression analysis we found that P-gp activity and Akt phosphorylation were independent poor prognostic factors of overall survival (OS). In contrast, phosphorylated extracellular signal-regulated kinase 1/2 (ERK1/2) represented a favorable prognostic factor of OS and relapse-free survival (RFS). A negative correlation between P-gp activity and p38 phosphorylation level was found, implying a possible role of this MAPK pathway in P-gp regulation. In addition, we found correlation between Akt and p38 phosphorylation levels, indicative of co-activation of two signaling cascades in AML.

Acute lymphoblastic leukemia (ALL) is a malignant disease of lymphoid precursors. According to immunophenotype, it is further subdivided into precursor B cell ALL and precursor T cell ALL, with ...precursor B cell ALL being much more common both in children and adults. Lineage switch from one lymphoid lineage to another during the course of the disease is extremely rarely reported. Here, we describe a case of a child who initially presented as a precursor B-ALL but 15 years later and after two successfully treated relapses of the original ALL presented with early T cell precursor leukemia. Although it was considered as a relapse, it could be interpreted as a case of secondary leukemia, which can be explained as a consequence of treatment as well as a constitutional feature of an individual. Also, it draws attention to the possibility that hematopoietic cells, and in that context also leukemic cells, are much more plastic and capable of reprogramming than previously thought.

Haemoglobinopathies are hereditary disorders of globin chain synthesis and are the most common inherited diseases worldwide. Haemoglobin E is a structural haemoglobin variant characteristic for South ...East Asian population. We present a rare and unusual finding of haemoglobin E detected in University Hospital Centre Zagreb by capillary zone electrophoresis. Detection of haemoglobin structural variant helped to avoid misdiagnosis of sideropenic anemia and thus potentially harmful therapeutic intervention. In today's European multiethnic population haemoglobinopathies are a public health issue and Croatian laboratory professionals should be aware of a possibility of finding an unusual haemoglobin pattern.
