Although thiopurine S-methyltransferase (TPMT) genotyping to guide thiopurine dosing is common in the pediatric cancer population, limited data exist on TPMT testing implementation in diverse, multidisciplinary settings. We established TPMT testing (genotype and enzyme) with clinical decision support, provider/patient education, and pharmacist consultations in a tertiary medical center and collected data over 3 years. During this time, 834 patients underwent 873 TPMT tests (147 (17%) genotype, 726 (83%) enzyme)...

Stroke-prone spontaneously hypertensive rats (SHRSP) on high-salt diet are characterized by extremely high arterial pressures, and have been endorsed as a model for hypertensive small vessel disease and vascular cognitive impairment. However, rapidly developing malignant hypertension is a well-known cause of posterior reversible encephalopathy syndrome (PRES) in humans, associated with acute neurological deficits, seizures, vasogenic cerebral edema and microhemorrhages. In this study, we aimed to examine the overlap between human PRES and SHRSP on high-salt diet...

Talaromyces marneffei, previously known as Penicillium marneffei, is the most important pathogenic thermally dimorphic fungus causing systemic mycosis in Southeast Asia. Traditionally, T. marneffei infection in human was mainly associated with acquired immunodeficiency syndrome caused by HIV infection. In recent years, there has been an increasing number of T. marneffei infections reported in non-HIV-infected patients with other immunocompromised conditions, including autoantibodies against interferon-gamma, systemic lupus erythematosis, solid organ transplantation, Job's syndrome, hematological malignancies, and use of novel targeted therapies...

Background -Anthracyclines, such as doxorubicin (DOX), are potent anti-cancer agents for the treatment of solid tumors and hematological malignancies. However, their clinical use is hampered by cardiotoxicity. This study sought to investigate the role of PI3Kγ in DOX-induced cardiotoxicity and the potential cardio-protective and anti-cancer effects of PI3Kγ inhibition. Methods -Mice expressing a kinase-inactive PI3Kγ or receiving PI3Kγ selective inhibitors were subjected to chronic DOX treatment. Cardiac function was analyzed by echocardiography and DOX-mediated signaling was assessed in whole hearts or in isolated cardiomyocytes...

Spurious thrombocytopenia is a well-known phenomenon observed with the widespread use of hematology analyzers (HAs). In this study, 355 specimens with pseudo-thrombocytopenia (PTCP) were evaluated via epidemiology, identification, remedies, and platelet (PLT) count. Data showed that anticoagulants such as citrate and/or heparin-dependent PTCP (16.0%) became increasingly common, whereas ethylenediaminetetraacetic acid (EDTA)-induced PTCP (49.1%) remained the most frequent. We note that that nearly half of the patients with PTCP had veritable decreased PLT counts, even after PLT levels had been corrected...

Allogeneic hematopoietic cell transplantation (HCT) is the treatment of choice for a variety of hematologic malignancies and disorders. Unfortunately, acute graft-versus-host disease (GVHD) is a frequent complication of HCT. While substantial research has identified clinical, genetic and proteomic risk factors for acute GVHD, few studies have sought to develop risk prediction tools that quantify absolute risk. Such tools would be useful for: optimizing donor selection; guiding GVHD prophylaxis, post-transplant treatment and monitoring strategies; and, recruitment of patients into clinical trials...

Autophagy leads cells to different fates in various cell types and under diverse contexts. Chronic lymphocytic leukemia (CLL), an incurable hematologic neoplasm, has highly variable course and its heterogeneity prompts interest in exploring autophagic trajectories in CLL. We detected the mRNA levels of two autophagy-related genes, BECN1 and ATG5, assessed the association between expression levels and clinical characteristics, and did survival analysis. One hundred and six patients with CLL and fifty healthy controls were enrolled in the present study...

Differentiation therapy of acute promyelocytic leukemia with all-trans retinoic acid represents the most successful pharmacological therapy of acute myeloid leukemia (AML). Numerous studies demonstrate that drugs that inhibit mechanistic target of rapamycin (mTOR) and activate AMP-kinase (AMPK) have beneficial effects in promoting differentiation and blocking proliferation of AML. Most of these drugs are already in use for other purposes; rapalogs as immunosuppressants, biguanides as oral antidiabetics, and 5-amino-4-imidazolecarboxamide ribonucleoside (AICAr, acadesine) as an exercise mimetic...

Acute myeloid leukemia (AML) is a hematological malignancy in which the immune response serves a pivotal role in progression. Aryl hydrocarbon receptor (AHR) is involved in the modulation of the immune system, particularly in the differentiation of T-helper cell (Th) subsets. Although the NLR family pyrin domain-containing 3 (NLRP3) inflammasome has been implicated as essential in the pathogenesis of autoimmune and inflammatory diseases, the role it serves in the development of AML remains unknown. Therefore, in order to identify and describe the possible roles of AHR, as well as NLRP3 inflammasome, in the pathogenesis of AML and their relationship with Th subsets (Th1 Th22), the present study investigated the mRNA expression levels of AHR and NLRP3 inflammasome molecules in the peripheral blood and bone marrow...

Unstable isotopes and their capacity to emit ionizing radiation have been employed in clinical practice not only for diagnostic, but also for therapeutic purposes, with significant contribution in several fields of medicine and primarily in the management of oncologic patients. Their efficacy is associated with their ability to provide the targeted delivery of ionizing radiation for a determined duration. These compounds can be used for curative or palliative treatment, as well as for a diagnostic-therapeutic (theranostic) approach...

Chidamide, a histone deacetylase (HDAC) inhibitor, has been applied in clinical trials for various types of hematological and solid tumors. Although acquired resistance is common in chemotherapy, the mechanism of resistance to chidamide is poorly characterized. The goal of the present study was to explore, in detail, the mechanism for the induced resistance to chidamide, and investigate a potential cross-resistance to other chemotherapeutic drugs. A549 cells were exposed to gradually increasing chidamide concentrations to establish a chidamide-resistant non-small cell lung cancer cell line (A549-CHI-R)...
