BACKGROUND: Blood loss due to phlebotomy leads to hospital-acquired anemia and more frequent blood transfusions that may be associated with increased risk of morbidity and mortality in critically ill patients. Multiple blood conservation strategies have been proposed in the context of patient blood management to minimize blood loss. Here, we evaluated a new small-volume sodium citrate collection tube for coagulation testing in critically ill patients. METHODS: In 46 critically adult ill patients admitted to an interdisciplinary intensive care unit, we prospectively compared small-volume (1...

BACKGROUND: The prognostic value of the acute phase protein Pentraxin 3 (PTX-3) is not well evaluated in patients with septic shock, which reveal an unacceptably high short- and long-term mortality. New Sepsis-3 definitions are not yet implemented in most biomarker studies. Therefore, this study assesses the prognostic value of PTX-3 for short- and mid-term mortality in patients with sepsis or septic shock, as defined by the latest definitions, treated at a medical intensive care unit (ICU)...

BACKGROUND: ClC-3 is involved in the proliferation and migration of several cancer cells. However, ClC-3 expression and its role of cell-cycle control in multiple myeloma (MM) has not yet been investigated. METHODS: MM cells were treated with different concentrations of IGF (30, 100, 300 ng/mL), and their proliferation was examined by CCK-8. The effects of ClC-3 on cell cycle progression was detected by flow cytometry. Western blot was used to analyze the relative levels of ClC3, CD138, P21, P27, CDK, p-Erk1/2, and t-Erk1/2 protein expression...

BACKGROUND: Myocardial infarction (MI) is an irreversible damage of myocardial tissue caused by prolonged ischemia and hypoxia. A local hypoxia-induced inflammation causes recruitment of leukocytes to the inflammatory site to aid cardiac remodeling and tissue healing. Among various chemokines involved in the process, CCL22 plays an essential role in cardiac cell migrations. In this study, we evaluated the incidence of rs4359426 and rs2228428 SNPs in CCL22/CCR4 genes of MI patients and studied their association with the physiology of the disease...

BACKGROUND: Cold agglutinin disease is a very rare condition associated with agglutination of erythrocytes in cold environment usually due to IgM type antibodies. Other than hemolytic anemias, it may interfere with routine hemogram tests due to miscalculation of red blood cell count (RBC) and other hemogram parameters calculated with involvement of RBC. Awareness of the condition is important to overcome laboratory errors. METHODS: We studied a peripheral blood smear and repeated the hemogram test at 37°C to establish the diagnosis of cold agglutinin disease...

BACKGROUND: Pseudothrombocytopenia, caused by platelet (PLT) clumping, is often found in clinical studies [1]. However, pseudothrombocytosis resulting from the fragmentation of red blood cells (RBCs) is a very rare phenomenon. METHODS: EDTA-K2 anticoagulation was used on a sample of venous blood extracted from the patient. A Symex XN9000 automatic blood analyzer was used to conduct CBC + DIFF mode and CBC + DIFF + RET mode tests, stained smear microscopy. RESULTS: The Symex XN9000 automatic blood analyzer was used to conduct CBC + DIFF mode test; PLTs were measured at 570 x 109/L...

BACKGROUND: We report a case of immunoglobulin (Ig) D myeloma with hidden lambda light chains in a patient whose immunofixation test was very difficult to interpret: the IgD reacts with the anti-δ heavy chain antiserum but does not react with anti-lambda antiserum. The band in the D heavy chain lane is unmatched in light chain lanes and the band in lambda light chain lane migrates higher. METHODS: To distinguish between heavy chain disease and immunoglobulin with "hidden" light chains, the sample was exposed to a very high concentration of anti-lambda and anti-kappa antisera for 48 hours...

BACKGROUND: Glioma is one of the most common and aggressive malignant tumors of the central nervous system. METHODS: Here, we review and explore the use of long noncoding RNA (lncRNA) as a therapeutic strategy for the targeting of gliomas. RESULTS: LncRNA is a functional RNA molecule with no protein coding function and is involved in the occurrence and progression of glioma. It is reported that the activation of several signaling pathways, including the MAPK, p53, Wnt/β-catenin, PI3K/AKT/mTOR, and epithelial mesenchymal transformation (EMT) pathways, are involved in the regulation of gliomas...
