What Constitutes a "Good Death"?-A Representative Cross-Sectional Survey Among the General Public in Croatia.

Understanding the attitudes of a particular society on a "good death" is important when it comes to end-of-life decision-making and palliative care. In the Republic of Croatia no systematic research has been done on the attitudes of the general population about the concept of a "good death". This cross sectional survey was conducted on a three-stage random sample, stratified by regions, counties and locations within those counties (N = 1203) during November and December, 2019. ANOVA, to determine differences, factor analysis and multiple regression analysis were used. The most important characteristics of a good death outlined by the respondents were: the absence of pain, the presence and unencumberedness of family and loved ones, the importance of a sense of fulfilment and meaning in life in this regard, reconciliation with God, the presence of awareness and sobriety, and the possibility of treatment.

Abdominal aortic and iliac aneurysm presented as lower limb deep vein thrombosis: case report.

Introduction: We report a rare case of a symptomatic abdominal aneurysm presented as a lower limb deep vein thrombosis (DVT).Case presentation: A 63-year old male presented to our hospital with a recent progressive onset of the right lower limb swelling and pain. The patient had a history of a previous cardiovascular disease. A Duplex ultrasound was performed, which confirmed a right lower limb DVT extending to the right iliac vein. The patient had a pulsatile abdominal mass. Computed tomography scan of the abdomen showed an abdominal aortic and a right iliac artery aneurysm compressing the thrombosed inferior caval and the right iliac vein. The patient was treated with low molecular weight heparin. After resolution of the DVT on day 3 of hospitalization, a surgery on the abdominal and iliac artery aneurysm was performed. The aneurysm was resected and an aortobifemoral bypass was placed using a Dacron prosthesis. The patient remained to be asymptomatic for 6 months after the surgery. Follow up computed tomography demonstrated a fully patent inferior caval and iliac vein and the absence of the aneurysmal disease.Conclusion: Although rare, our case confirms that the DVT should be considered as a possible symptom of an abdominal aneurysm in selected patients.

The frequencies of micronuclei, nucleoplasmic bridges and nuclear buds as biomarkers of genomic instability in patients with urothelial cell carcinoma.

Bladder urothelial cell carcinoma (UCC) is an increasingly prevalent cancer worldwide, and thus, gaining a better understanding of its identifiable risk factors is a global priority. This study addressed this public health need with the understanding that cancer-initiating events, such as chromosome breakage, loss and rearrangement, can be reasonably used as biomarkers to evaluate an individual's cancer risk. Overall, forty bladder cancer patients and twenty controls were evaluated for genomic instability. To the best of the investigators' knowledge, this is the first study to perform micronucleus (MN) assays simultaneously in urothelial exfoliated cells (UEC), buccal exfoliated cells (BEC), and peripheral blood lymphocytes (PBL) in first-diagnosed, non-smoker bladder UCC patients. Additionally, the frequency of nucleoplasmic bridges (NPBs) and nuclear buds (NBUDs) in PBL was evaluated. The MN frequencies in UEC, BEC, and PBL, as well as the frequencies of NPBs and NBUDs, were significantly higher in patients than in controls. In conclusion, MN assays, particularly in UEC, may be used to identify individuals who are at high risk of developing UCC, as single or as additional triage test to UroVysion FISH test. Our results further validate the efficacy of biomarkers, such as MN, NPBs, and NBUDs, as predictors of genomic instability.

Coil embolization and surgical removal of carotid body paraganglioma.

Carotid body paraganglioma has considerable malignant potential and locally aggressive behavior, so it should be treated as soon as it is discovered.We report the case of 60-year-old male patient with a carotid body paraganglioma (Shamblin group II) that was causing the carotid arteries to spread. Angiography showed 1 dominant feeding artery arising from the right external carotid artery. Selective angiography was performed 2 days before surgical removal of the tumor, and the feeding artery was successfully embolized with coils.Literature review reveals previous reports where preoperative embolization of the feeding arteries was done using ethanol, polymers, or other liquid agents. In our case, angiography (via femoral artery) was performed 2 days before surgical removal of the tumor, and the main feeding artery (a single branch arising from external carotid artery) was successfully embolized with coils rather than liquids.Performing coil embolization before operating reduced subsequent blood loss and made it easier to identify the feeding artery during surgery. Supraselective coiling, although as difficult as embolization with liquids, may reduce the incidence of postoperative stroke. At 1 year after surgery, the patient had no signs of tumor recurrence.

[The unclassifiable myeloproliferative neoplasm--morphological, cytogenetic and clinical features]. / Neklasificirana mijeloproliferativna neoplazma--morfoloske, citogenetske i klinicke karakteristike.

Myeloproliferative neoplasm, unclassifiable (MPN,U) has clinical, laboratory and morphological features of an MPN but fails to meet the criteria for any of the specific MPN entities. Because overlapping features, morphological findings in bone marrow, BCR-ABL1 fusion gene, V617F JAK2 mutation and cytogenetic abnormalities were analyzed in ten patients diagnosed with MPN,U. Bone marrow biopsy showed hypercellularity with trilineage myeloproliferation, dispersed megakaryocytes with mild pleomorphism and mature nuclei, and absence of reticulin fibrosis. All patients were BCL-ABL1 negative, while V617F JAK2 mutation was found in 6 of 8 patients. Trisomy 8 was found in two patients and t(6;12)(q12;p13) in one patient. Morphological features of MPN,U are nonspecific, however, in study cases they were most similar to diagnostic morphological features of polycythemiea vera. The high frequency of V617F JAK2 mutation in MPN,U cases analyzed revealed that its presence does not confirm a specific type of MPN.

Immunohistochemical localization of CD31, NOTCH1 and JAGGED1 proteins in experimentally induced polycystic ovaries of immature rats.

We analyzed histomorphometrical changes and blood vessel immunohistochemical staining of CD31, NOTCH1 and JAGGED1 in induced polycystic ovaries of immature female Wistar rats, as well as serum hormone levels. The rats were randomly divided into control (n=18) and treated (n=18) groups. Treated animals received intramuscularly testosteronenantat weekly (0.1mg/g). Controls received the same amount of ricinus oil. Rats were weighed daily. Control and treated subgroups (6 rats per subgroup) were subsequently sacrificed after 21, 28 and 35 days of treatment. In ovaries of treated rats we found large cystic follicles, thick stromal tissue, many atretic preantral follicles, no ovulation and a thinner granulosa cell layer. CD31 stained blood vessels in the theca layer were reduced, with reduced JAGGED1 and NOTCH1 immunostaining. In controls, preantral and antral follicles were larger than in the treated group. Treated animals showed statistically significant lower progesterone and higher testosterone levels. They gained more weight than controls. Reduced immunostaining for NOTCH1 and JAGGED1 of reduced blood vessels of the theca layer was found in all stages of folliculogenesis with a distinct reduction in cystic and atretic follicles. Our results provide evidence of intrinsic abnormality during all stages of folliculogenesis in polycystic ovaries and this may result from crosstalk between circulating gonadotropins and follicular angiogenesis.

Prognostic significance of B-cell differentiation genes encoding proteins in diffuse large B-cell lymphoma and follicular lymphoma grade 3.

AIM: To define prognostic significance of B-cell differentiation genes encoding proteins and BCL2 and BCL6 gene abnormalities in diffuse large B-cell lymphoma and follicular lymphoma grade 3 with >75% follicular growth pattern. METHODS: In 53 patients with diffuse large B-cell lymphoma and 20 patients with follicular lymphoma grade 3 with >75% follicular growth pattern the following was performed: 1) determination of protein expression of BCL6, CD10, MUM1/IRF4, CD138, and BCL2 by immunohistochemistry; 2) subclassification into germinal center B-cell-like (GCB) and activated B-cell-like (ABC) groups according to the results of protein expression; 3) detection of t(14;18)(q32;q21)/IgH-BCL2 and BCL6 abnormalities by fluorescent in situ hybridization in diffuse large B-cell lymphoma and follicular lymphoma grade 3 with >75% follicular growth pattern as well as in GCB and ABC groups; and 4) assessment of the influence of the analyzed characteristics and clinical prognostic factors on overall survival. RESULTS: Only BCL6 expression was more frequently found in follicular lymphoma grade 3 with >75% follicular growth pattern than in diffuse large B-cell lymphoma (P=0.030). There were no differences in BCL2 and BCL6 gene abnormalities between diffuse large B-cell lymphoma and follicular lymphoma grade 3 with >75% follicular growth pattern. Diffuse large B-cell lymphoma and follicular lymphoma grade 3 with >75% follicular growth pattern patients were equally distributed in GCB and ABC groups. t(14;18)(q32;q21) was more frequently recorded in GCB group, and t(14;18)(q32;q21) with BCL2 additional signals or only BCL2 and IgH additional signals in ABC group (P=0.004). The GCB and ABC groups showed no difference in BCL6 gene abnormalities. There was no overall survival difference between the diffuse large B-cell lymphoma and follicular lymphoma grade 3 with >75% follicular growth pattern patients, however, GCB group had longer overall survival than ABC group (P=0.047). Multivariate analysis showed that BCL6, CD10, and BCL2 expression, BCL2 and BCL6 abnormalities, and International Prognostic Index were not significantly related to overall survival. CONCLUSION: Diffuse large B-cell lymphoma and follicular lymphoma grade 3 with >75% follicular growth pattern patients have very similar characteristics and their prognosis is more influenced by protein expression of B-cell differentiation stage genes than by tumor cells growth pattern, BCL2 and BCL6 abnormalities, and International Prognostic Index.

MALT1, BCL10 and FOXP1 in salivary gland mucosa-associated lymphoid tissue lymphomas.

In view of the certain anatomic site-dependent frequency of chromosomal translocations involved in extranodal marginal zone B cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) pathogenesis, 17 salivary gland MALT lymphoma cases were analyzed for MALT1 and FOXP1 translocations. B cell CLL/lymphoma 10 (BCL10) and forkhead box PA (FOXP1) protein expression were studied by immunohistochemistry and translocations identified using fluorescence in situ hybridization (FISH)-specific probes FOXP1, t(11;18)(q21;q21)/API2-MALT1 and t(14;18)(q32;q21)/IgH-MALT1. None of the 11 analyzed cases showed FOXP1 rearrangement or amplification. The t(11;18) was present in five of 13 cases and the t(14;18) in three of 13 cases. MALT1 translocations were mostly mutually exclusive except in a single case. FOXP1 protein expression showed differences in the proportion of tumor cells with nuclear expression but not in their intensity, with the exception of one case where very intense nuclear staining was noted. BCL10 nuclear expression was present in four of 17 cases, two of which lacked t(11;18). Our results suggest that MALT1-specific translocations and FOXP1 rearrangements are not commonly involved in pathogenesis. A case with strong FOXP1 protein expression indicates the possibility that the upregulation of FOXP1 expression is significant in a small subset of salivary gland MALT lymphomas. Also a single case in which both MALT1 translocations were present indicates that these are not always mutually exclusive.

Bone marrow lymphoid aggregates in malignant lymphomas.

AIM: To examine the usefulness of molecular analysis of IgH gene rearrangement in assessment of clonality in bone marrow biopsies with lymphoid aggregates (LA) and/or nodular lymphoid hyperplasia (NLH) in patients with different subtypes of malignant lymphomas. METHOD: Five hundred and twenty nine samples of bone marrow biopsies, taken in a staging procedure at the time of the initial presentation of illness, were processed routinely. Results were grouped in positive, negative, and cases with LA or NLH. In 43 samples with present LA/NLH, polymerase chain reaction (PCR) analysis of the CDR3 region of immunoglobulin heavy chain gene (IgH) for B-cell clonality was performed. RESULTS: Bone marrow malignant lymphoma infiltrates were present in 33.8% of lymphoma cases. The incidence of LA/NLH in bone marrow was 8.1%. LA/NLH were more frequently found in patients with extranodal disease and aggressive subtypes of B cell non-Hodgkin lymphoma (B-NHL), but there was no significant difference among the incidence according to the biological behavior of malignant lymphoma (P=0.232). Results of IgH-CDR3 region PCR analysis showed a monoclonal pattern in 1 case of Hodgkin lymphoma and in 1 control case, an oligoclonal pattern in 2 cases of extra nodal B-NHL, whereas all other had polyclonal. CONCLUSION: The results support our initial hypothesis that LA/NLH could be differentiated from malignant infiltrates in bone marrow staging procedure of malignant lymphoma by topographic pattern and histocytomorphology of LA/NLH. Surprisingly, our patients with aggressive B-NHL, nodal, as well as extranodal, had LA/NLH in bone marrow biopsies more often than patients with indolent B-NHL.
