BACKGROUND: Recently a novel syndromic form of overgrowth with intellectual disability and distinct facial features was identified caused by constitutional mutations in the epigenetic regulator DNA-methyltransferase 3A (DNMT3A), referred to as Tatton-Brown-Rahman syndrome (TBRS). Somatically acquired mutations in DNMT3A occur in haematological malignancies and are frequently present in acute myeloid leukaemia (AML) affecting in more than 50% the arginine residue at position 882 (R882)...

To elucidate the influence of dietary carnosic acid (CA) and vitamin E on animal performance, immune response indicators and haematological parameters before and after transport stress, 24 lambs were individually fed ad libitum with milk replacer (MR) using an auto-feeder. Once daily the lambs received MR alone (Group CON, n = 8), MR + 0.096 g CA/kg live weight (LW) (Group CARN, n = 8) or MR + 0.024 g of α-tocopheryl acetate per kg LW (Group VitE, n = 8). After reaching the target slaughter weight (12 ± 0...

Age is a well-known factor in solid tumours linked to lower adherence to guidelines. Scarce data exist for haematologic malignancies such as multiple myeloma (MM). The aim of the study was to investigate the relationships among age, adherence to guidelines in MM, and overall survival (OS).The Poitou-Charentes cancer registry has exhaustively registered incident cases of MM from 2008 to 2010. Diagnosis, staging, prognosis, and first-line treatment were compared to the international guidelines. Three hundred and sixty-seven patients aged 36 to 93 years were included...

Pancreatic ductal adenocarcinoma is a devastating disease with a poor prognosis regardless of stage. To date the mainstay of therapy for advanced disease has been chemotherapy with little incremental improvements in outcome. Despite extensive research investigating new treatment options the current practices continue to utilise fluorouracil or gemcitabine containing combinations. The need for novel therapeutic approaches is mandated by the ongoing poor survival rates associated with this disease. One such approach may include manipulation of ribosome biogenesis and the nucleolar stress response, which has recently been applied to haematological malignancies such as lymphoma and prostate cancer with promising results...

The HOX and PBX gene families encode transcription factors that have key roles in establishing the identity of cells and tissues in early development. Over the last 20 years it has become apparent that they are also dysregulated in a wide range of solid and haematological malignancies and have a predominantly pro-oncogenic function. A key mode of transcriptional regulation by HOX and PBX proteins is through their interaction as a heterodimer or larger complex that enhances their binding affinity and specificity for DNA, and there is growing evidence that this interaction is a potential therapeutic target in malignancies that include prostate, breast, renal, ovarian and lung cancer, melanoma, myeloma, and acute myeloid leukaemia...

BACKGROUND: Hepatic sinusoidal obstruction syndrome (SOS) during treatment of childhood acute lymphoblastic leukemia (ALL) has mainly been associated with 6-thioguanine. The occurrence of several SOS cases after the introduction of extended pegylated asparaginase (PEG-asparaginase) therapy in the Nordic Society of Paediatric Haematology and Oncology (NOPHO) ALL2008 protocol led us to hypothesize that PEG-asparaginase, combined with other drugs, may trigger SOS during 6-thioguanine-free maintenance therapy...

INTRODUCTION: Preoperative anaemia is linked to poor postsurgical outcome, longer hospital stays, greater risk of complications and mortality. Currently in the UK, some sites have developed anaemia clinics or pathways that use intravenous iron to correct iron deficiency anaemia prior to surgery as their standard of care. Although intravenous iron has been observed to be effective in a variety of patient settings, there is insufficient evidence in its use in cardiac and vascular patients...

OBJECTIVE: Research indicates that health personnel (HP) caring for seriously ill patients with dependent children aged 0-18 often avoid discussing with them the challenges of being a family with a parent in treatment. Children of seriously ill patients (CSIP) risk serious trauma and emotional difficulty later in life and depend on adult support to minimize these consequences. Patients suffer anxiety about supporting their children during their illness. Due to their potentially pivotal role in supporting patients in enabling parent-child communication, we examined HP's structural and emotional barriers to communicating with patients about their children...

Iron chelation is controversial in higher risk myelodysplastic syndromes (HR-MDS), outside the allogeneic transplant setting. We conducted a retrospective, multicentre study in 51 patients with transfusion-dependent, intermediate-to-very high risk MDS, according to the revised international prognostic scoring system, treated with the oral iron chelating agent deferasirox (DFX). Thirty-six patients (71%) received azacitidine concomitantly. DFX was given at a median dose of 1000 mg/day (range 375-2500 mg) for a median of 11 months (range 0·4-75)...

Ribociclib is an oral, small-molecule inhibitor of cyclin-dependent kinase (CDK) 4 and 6 that is under development by Novartis for the treatment of cancer. CDKs play an important role in cell cycle progression and cellular proliferation, and inhibition of these kinases with ribociclib results in G1 phase cell-cycle arrest. Ribociclib, in combination with an aromatase inhibitor, was recently approved in the USA for the first-line treatment of advanced breast cancer and has been submitted for approval in the EU for this indication...

Haematological malignancies are tumours that affect the haematopoietic and the lymphatic systems. Despite the huge efforts to eradicate these tumours, the percentage of patients suffering resistance to therapies and relapse still remains significant. The tumour environment favours drug resistance of cancer cells, and particularly of cancer stem/initiating cells. Hypoxia promotes aggressiveness, metastatic spread and relapse in most of the solid tumours. Furthermore, hypoxia is associated with worse prognosis and resistance to conventional treatments through activation of the hypoxia-inducible factors...

Purine nucleoside analogues are widely used in the treatment of haematological malignancies, and their biological activity is dependent on the intracellular accumulation of their triphosphorylated metabolites. In this context, we developed and validated a liquid chromatography tandem mass spectrometry (LC-MS/MS) method to study the formation of 5'-triphosphorylated derivatives of cladribine, fludarabine, clofarabine and 2'-deoxyadenosine in human cancer cells. Br-ATP was used as internal standard. Separation was achieved on a hypercarb column...

BACKGROUND: Clotting parameters are informative of overall haematological healthiness of an individual. Particularly, clotting parameters can be used as a measure of the degree of pathology of the coagulation system. Thromboelastography (TEG) is a well-known technique that is an important point-of-care method, as well as research method. Scanning electron microscopy (SEM) is a novel research method, but with possible clinical application. However, there are no clear standardized guidelines for TEG and SEM result interpretation...
