The Aurora kinase family facilitates cell division through various processes and is overexpressed in a wide variety of human cancers, leading to aneuploidy. For that reason, these enzymes are currently targets of a rising class of anticancer drugs, with some molecules already in therapeutic use. In this study, a new UHPLC-MS/MS method was developed and validated to quantitate a new pan Aurora kinase inhibitor still in preclinical development, SCH-1473759. This bioanalytical method employed a liquid-liquid extraction from plasma using ethyl acetate before evaporation...

The hematocrit (Hct) determines the oxygen carrying capacity of blood, but also increases blood viscosity and thus flow resistance. From this dual role the concept of an optimum Hct for tissue oxygenation has been derived. Viscometric studies using the ratio Hct/blood viscosity at high shear rate showed an optimum Hct of 50-60% for red blood cell (RBC) suspensions in plasma. For the perfusion of an artificial microvascular network with 5-70μm channels the optimum Hct was 60-70% for high driving pressures. With lower shear rates or driving pressures the optimum Hct shifted towards lower values...

BACKGROUND: Cryptococcal meningitis is common and associated with high mortality among HIV infected persons. The World Health Organization recommends that routine Cryptococcal antigen (CrAg) screening in ART-naïve adults with a CD4+ count <100 cells/μL followed by pre-emptive antifungal therapy for CrAg-positive patients be considered where CrAg prevalence is ≥3%. The prevalence of CrAg among HIV adults in Namibia is unknown. We estimated CrAg prevalence among HIV-infected adults receiving care in Namibia for the purpose of informing routine screening strategies...

Management of hypertension in diabetes is critical for reducing cardiovascular mortality and morbidity. Dietary approaches for controlling high blood pressure have historically focused on sodium. Thus, many guidelines recommend that patients with type 2 diabetes reduce high sodium intake. Nonetheless, the potential benefits of sodium reduction are debatable. The kidney has a crucial role in glucose filtration and reabsorption in addition to its regulation of fluid and electrolyte homeostasis. A key factor linking sodium uptake and glucose transport is the sodium-glucose cotransporter 2 (SGLT2) in renal proximal tubular cells...

BACKGROUND: Massive transfusion protocols (MTPs) have been adopted in many hospitals, and they may improve outcomes, as well as decrease the number of blood products transfused. However, there are no specific guidelines regarding the number and types of products that should be included in these protocols. MTPs may vary from hospital to hospital. METHODS: A short, web-based survey was sent to blood bank medical directors at academic institutions to learn details about MTPs...

Intracerebral hemorrhage (ICH) remains a cause of death in hematologic malignancies. Asparaginase represents a key agent in the treatment of acute lymphoblastic leukemia (ALL). The toxicity of asparaginase includes coagulopathy such as thrombotic or bleeding tendency. We report a case of fatal cerebral hemorrhage in a 12-year-old girl treated for ALL. Cerebral hemorrhage occurred after three injections of L-asparaginase. The patient presented with hypofibrinogenemia (0.36g/L), associated with thrombocytopenia (24,000/mm(3))...

Cytogenetics of multiple myeloma has evolved in recent years by the emergence of Interphasic fluorescence in situ hybridization (FISH) performed on sorted plasma cells detecting abnormalities independently of a proliferative and infiltrative index. Cytogenetic analysis plays a major part in the risk stratification of myeloma diagnosis due to prognostic impact of various cytogenetic abnormalities as well as to the association between emerging therapeutic approaches in MM. Thus, practice guidelines now recommend interphasic FISH or alternative molecular technics as the initial analysis for multiple myeloma...

In the present study, the case of a 41-year-old man with immunoglobulin (Ig)M multiple myeloma (MM) that presented with an unusually non-aggressive clinical course who has survived for >9 years to date, is presented. Initial diagnosis of symptomatic MM was established according to the International Myeloma Working Group consensus statement and guidelines. Due to the mild symptoms, no therapy was administered and the patient was closely followed up. Eight years after initial diagnosis, clinical, morphological and genetic progression occurred with the development of hypercalcemia, progressively deteriorating polyneuropathy, clonal expansion of plasma cells up to 50% of hematopoietic cells and demonstration of the typical t(11;14) translocation (Ig heavy chain locus rearrangement)...

The use of platelet rich plasma (PRP) spans across many fields owing to its role in healing and as a natural alternative to surgery. PRP continues to grow however much of the literature is anecdotal or case report based and there is a lack of controlled trials to evaluate standards for PRP. The International Cellular Medical Society (ICMS) has developed guidelines to help with the safe advancement of PRP; however there remains a gap in literature concerning the timing of PRP injections in patients who are on antithrombotic therapy...

The acute and subacute toxicity profile of the aerial extract of Monsonia angustifolia in Wistar rats was evaluated. The Organization for Economic Cooperation and Development (OECD) 420 guideline was adopted in the acute toxicity testing with a single oral dose of 5000 mg/kg (b.w.). For the 28-day daily oral dosing, the extract was administered at 75, 150, and 300 mg/kg b.w.; 1% ethanol in sterile distilled water was used as control. Clinical toxicity signs were subsequently evaluated. At a single dose of 5000 mg/kg b...

Multiple myeloma (MM) is an incurable plasma cell neoplasm with an incidence of 100 patients per year in Singapore. Major advances have been made in the diagnosis, risk stratification and treatment of MM in the recent past. The reclassification of a subset of patients with smouldering MM, based on high-risk biomarkers, and the development of the revised international staging system are among the key new developments in diagnosis and staging. The use of novel agent-based treatment has resulted in significant improvements in the survival and quality of life of many patients with MM...

The authors report a case of immunoglobulin G4-related disease (IgG4-RD) presenting as a paraspinal, epidural mass. This disease encompasses a host of autoimmune conditions that were previously thought to be separate entities. It is characterized by fibrosis, mediated by the aberrant proliferation and tissue invasion of IgG4-positive plasma cells, which can occur in any organ. As with other autoimmune conditions, it tends to be responsive to steroids and other immunosuppressants. It can rarely present as a tumefactive lesion of the central nervous system, creating the potential for misdiagnosis (given its similar radiological appearance to malignancy) and mistreatment...

Plasma cell leukemia (PCL) is an uncommon neoplasm of plasma cells, with an aggressive clinical course and poor outcome, even with current standard of care. It can occur either de novo (primary PCL) or as a progression of multiple myeloma (MM). This disease has unique diagnostic criteria but certain genetic markers and clinical features may overlap with MM. Due to the low prevalence of PCL, guidelines on its management are extrapolated from the management of MM and based on small retrospective studies and cases reports/series...

BACKGROUND: Although patient blood management (PBM) programs clearly reduce transfusion overuse, the relative impact on red blood cell (RBC), plasma, and platelet (PLT) utilization is unclear. STUDY DESIGN AND METHODS: A retrospective analysis of electronic records was conducted at a medium-sized academic hospital to assess blood utilization for all inpatients admitted during 1-year periods before (n = 20,531) and after (n = 19,477) PBM efforts began in September 2014...

In recent years there has been a boom in the use of platelet-rich plasma (PRP) as an orthobiology (therapy based on cell biological agents) material agent. The presence of growth factors and other bioactive agents stored in alpha platelet granules and whose properties are well determined in cell proliferation, angiogenesis and extracellular matrix formation have involved the PRP containing supraphysiological concentrations of autologous platelets in tissue regeneration processes. The relative ease of preparation of PRP, its generally ambulatory application, the almost complete absence of side effects and the possibility to observe satisfactory results of clinical improvement makes the PRP a promising treatment in regenerative processes...

Autoimmune encephalitis (AIE) is a group of disorders in which autoantibodies directed at antigens located on the plasma membrane of neurons induce severe neurological symptoms. In contrast to classical paraneoplastic disorders, AIE patients respond well to immunotherapy. The detection of neuronal surface autoantibodies in patients' serum or CSF therefore has serious consequences for the patients' treatment and follow-up and requires the availability of sensitive and specific diagnostic tests. This mini-review provides a guideline for both diagnostic and research laboratories that work on the detection of known surface autoantibodies and/or the identification of novel surface antigens...
