Leucocytosis and thrombosis at diagnosis are associated with poor survival in polycythaemia vera: a population-based study of 327 patients
2012
Three hundred and twenty-seven patients from two population-based cohorts with an established diagnosis of polycythaemia vera were studied for prognostic risk factors for survival and leukaemia in a long-term survey. The relative survival (RS) was 72% and 46% at 10 and 20 years respectively, from the time of diagnosis. Multivariate analysis identified age >70 years, white blood cell count >13 × 10(9) /l and thrombo-embolism at diagnosis as independent risk factors. Patients with two or three of these factors had a 10 year RS of 26%, compared with 59% and 84% in patients with one and no risk factors, respectively. Age and leucocyte count are the main predicting factors for survival in polycy…
Myocardial infarction marker levels are influenced by prothrombin and tumor necrosis factor-α gene polymorphisms in young patients.
2012
Polymorphisms of genes encoding key factors for the control and activation of inflammatory response and coagulation cascade regulation may play a role in genetic susceptibility to acute myocardial infarction (AMI). This study sought to analyze the effect of TNF - 308G/A and pro-thrombin (FII) 20210G/A polymorphisms on the laboratory parameters of young patients affected by AMI. Results indicated that TNF - 308A positive genotype frequencies were increased in these patients and that a genetically determined higher production of TNF-alpha is associated in young subjects to a more severe cardiac damage as depicted by higher levels of troponin, Creatine kinase-MB Isoenzyme (mCK-MB) and a signif…
Foot health-related quality of life in hemophiliacs: A case-control study
2020
Background: Haemophilia is considered as a chronic genetic disease related with alteration in coagulation mechanism which affects to health related quality of life (HQoL). Purpose: The goal compared marks of HQoL, in haemophiliacs with respect non haemophilic subjects. Methods: A population of 74 subjects, were recruited from association of haemophilic illness separated in haemophilic subjects (n = 37) and no haemophilic (n = 37). For subjects who suffered haemophilia were enlisted from the association of haemophilic illness after a seminar of 45 minutes to them and to their relatives about foot health. Control subjects, were recruited from their relatives who live with the patient. The mar…
TC perfusionale nell'ischemia cerebrale acuta: Valore predittivo dei parametri di perfusione cerebrale nel discriminare il tessuto vitale da quello i…
2007
Purpose. The aim of this study was to assess the value of computed tomography (CT) perfusion parameters in differentiating tissue viability in acute stoke patients. Materials and methods. Thirteen patients (mean age 63.3 years) with nonhaemorrhagic stroke underwent multidetector perfusion CT within 3 h of symptom onset. Images were continuously acquired at the basal ganglia over 40 s during injection of 90 ml of iodinated contrast medium injected at a rate of 9 ml/s with a 9-s delay. Z-axis coverage was 20 mm. All patients underwent diffusion-weighted magnetic resonance imaging (DWI) within 12 h of perfusion CT to define the extent of the infarct. Perfusion CT data were analysed in regions …
Criteria for defining a complete remission in acute myeloid leukaemia revisited. An analysis of patients treated in HOVON-SAKK co-operative group stu…
2005
Complete remission (CR) in patients with acute myeloid leukaemia (AML) is the primary endpoint for the evaluation of induction treatment and treatment strategies. However, the choice and application of the criteria for a haematological CR can often become a subject of debate because of regeneration more than 5% blasts may be present at the time of response evaluation; platelet and neutrophil recovery may be incomplete and marrow cellularity can vary. This study examined the individual parameters for CR in 1250 adult patients with de novo AML treated according to three successive study protocols. Patients with < or =5% blasts showed the best overall survival (OS) and the lowest relapse risk …
Lipid-altering efficacy of ezetimibe/simvastatin 10/20 mg compared with rosuvastatin 10 mg in high-risk hypercholesterolaemic patients inadequately c…
2009
SUMMARY Aims: To evaluate the efficacy of switching from a previous statin monotherapy to ezetimibe ⁄simvastatin (EZE ⁄SIMVA) 10 ⁄20 mg vs. rosuvastatin (ROSUVA) 10 mg. Methods: In this randomised, double-blind study, 618 patients with documented hypercholesterolaemia [low-density lipoprotein cholesterol (LDL-C) ‡ 2.59 and £ 4.92 mmol ⁄l] and with high cardiovascular risk who were taking a stable daily dose of one of several statin medications for ‡ 6 weeks prior to the study randomisation visit entered a 6-week open-label stabilisation ⁄screening period during which they continued to receive their prestudy statin dose. Following stratification by study site and statin dose ⁄potency, patien…
Effects of cold atmospheric plasma (CAP) on bacteria and mucosa of the upper aerodigestive tract.
2019
Abstract Objective Ear, nose and throat infections are among the most common reasons for absence from work. They are usually caused by various bacteria like Haemophilus influenzae, Staphylococcus aureus, Streptococcus pneumoniae and Streptococcus pyogenes. Cold atmospheric plasma (CAP) can effectively eliminate even multi-resistant bacteria and has no cytotoxic or mutagenic effects on the mucosa when applied for less than 60 s. Aim of the study was to evaluate the effects of CAP on common ENT bacteria and on the mucosa of the upper aerodigestive tract. Methods The bactericidal effects of CAP against the bacteria most commonly causing ENT infections were investigated using the colony-forming…
CD146+ bone marrow osteoprogenitors increase in the advanced stages of primary myelofibrosis
2008
Abstract CD146+ bone marrow stromal cells have been recently recognized as clonogenic osteoprogenitors able to organize a complete hematopoietic microenvironment. In this study we used immunohistochemical analysis to investigate the contribution of CD146+ bone marrow osteoprogenitors to the stromal remodeling occurring in the different stages of primary myelofibrosis. We found that CD146+ cells sited at the abluminal side of the bone marrow vessels and branching among hematopoietic cells significantly increased in the advanced stages of primary myelofibrosis (p<0.001), paralleling the extent of fibrosis (r=0.916, p<0.0001) and the microvascular density (r=0.883, p<0.0001). Coherently with a…
Static magnetic fields generated by a 0.5T MRI unit affects in vitro expression of activation markers and interleukin release in human peripheral blo…
2001
To investigate the effects of the static magnetic field (SMF) generated by a 0.5 T superconducting MRI unit on in vitro activation marker expression and interleukin release in human peripheral blood mononuclear cell (PBMC) samples from healthy volunteers.PBMC samples were split into two groups: exposed and sham-exposed under isothermal conditions. PBMC were exposed for 2 h at 24 degrees C to the SMF of a 0.5 T superconducting MRI unit. Immediately after exposure, both samples were cultured for 24 h at 37 degrees C with or without mitogenic stimulation by phytohaemagglutinin (PHA). PBMC were examined for expression of CD25, CD69 and CD71 by immunofluorescence analysis and supernatants were a…
A novel role of the CX3CR1/CX3CL1 system in the cross-talk between chronic lymphocytic leukemia cells and tumor microenvironment
2011
Several chemokines/chemokine receptors such as CCR7, CXCR4 and CXCR5 attract chronic lymphocytic leukemia (CLL) cells to specific microenvironments. Here we have investigated whether the CX(3)CR1/CX(3)CL1 axis is involved in the interaction of CLL with their microenvironment. CLL cells from 52 patients expressed surface CX(3)CR1 and CX(3)CL1 and released constitutively soluble CX(3)CL1. One third of these were attracted in vitro by soluble CX(3)CL1. CX(3)CL1-induced phosphorylation of PI3K, Erk1/2, p38, Akt and Src was involved in induction of CLL chemotaxis. Leukemic B cells upregulated CXCR4 upon incubation with CX(3)CL1 and this was paralleled by increased chemotaxis to CXCL12. Akt phosp…
