Same-Day Identification and Antimicrobial Susceptibility Testing of Bacteria in Positive Blood Culture Broths Using Short-Term Incubation on Solid Medium with the MicroFlex LT, Vitek-MS, and Vitek2 Systems

Routine implementation of this short-term incubation method could provide ID results on the day of blood culture-positivity detection and one day earlier than the conventional AST method. This simple method will be very useful for rapid ID and AST of bacteria from positive blood culture bottles in routine clinical practice.

SJR Q1Scientific ReportsOA

The early detection and timely treatment are the most important factors for improving the outcome of patients with sepsis. Sepsis-related clinical score, such as SIRS, SOFA and LODS, were defined to identify patients with suspected infection and to predict severity and mortality. A few hematological parameters associated with organ dysfunction and infection were included in the score although various clinical pathology parameters (hematology, serum chemistry and plasma coagulation) in blood samp

Ig Gene Clonality Analysis Using Next-Generation Sequencing for Improved Minimal Residual Disease Detection with Significant Prognostic Value in Multiple Myeloma Patients
Jihye Ha, Hyeonah Lee, Saeam Shin, Hyunsoo Cho, Haerim Chung, Ji Eun Jang, Soo‐Jeong Kim, June‐Won Cheong, Seung‐Tae Lee, Jin Seok Kim, Jong Rak Choi
SJR Q1Journal of Molecular DiagnosticsOA

Next-generation sequencing (NGS) of rearranged Ig genes is an effective technology for identifying pathologic clonal cells in multiple myeloma (MM) and tracking minimal residual disease. The clinical effect of implementing NGS in Ig gene clonality analysis was evaluated via a retrospective chart review. A total of 312 patients diagnosed with MM were enrolled in the study. Ig gene clonality was determined by fragment analysis using BIOMED-2 multiplex PCR assays and by NGS using the LymphoTrack IG

Cytogenetic testing by fluorescence in situ hybridization is improved by plasma cell sorting in multiple myeloma

SJR Q1Scientific ReportsOA

Accurate detection of cytogenetic abnormalities has become more important for improving risk-adapted treatment strategies in multiple myeloma (MM). However, precise cytogenetic testing by fluorescence in situ hybridization (FISH) is challenged by the dilution effect of bone marrow specimens and poor growth of plasma cells ex vivo. It has been suggested that FISH should be performed in combination with plasma cell enrichment strategies. We examined cytogenetic abnormalities in newly diagnosed MM

Chronic Myeloid Leukemia With Rare Variant b2a3 (e13a3) BCR-ABL1 Fusion
Jihye Ha, June‐Won Cheong, Saeam Shin, Seung‐Tae Lee, Jong Rak Choi
SJR Q2Annals of Laboratory MedicineOA

Dear Editor, CML is characterized by reciprocal t(9;22)(q34;q11) translocation, which generates the BCR/ABL1 protein; that protein plays a critical role in the pathogenesis of CML. CML patients commonly harbor BCR-ABL1 fusion transcripts of types b3a2 (e14a2) or b2a2 (e13a2), while types e1a2 or e19a2 are less common. CML cases with b2a3-type fusion, in which the ABL1 exon 3 (a3) rather than exon 2 (a2) is fused to BCR, are rare. To date, only eight CML cases with solely b2a3-type fusion have

SJR Q2Annals of Laboratory MedicineOA

BACKGROUND: Epstein-Barr Virus (EBV) is one of the most prevalent causes of viral infection in humans. EBV infection stage (acute, past, or absent infection) is typically determined using a combination of assays that detect EBV-specific markers, such as IgG and IgM antibodies against the EBV viral capsid antigen (VCA) and IgG antibodies against the EBV nuclear antigen (EBNA). We compared the diagnostic performance and agreement of results between three commercial EBV antibody assays using an EBV

The genus Kytococcus are pigmented, non-encapsulated, non-motile, aerobic, catalase-positive, Gram-positive cocci in pairs or tetrads. We report a case of Kytococcus schroeteri isolated from a blood specimen of a patient with pneumonia. The isolate was Gram-variable and difficult to identify using conventional biochemical tests.

Abstract Accurate detection of cytogenetic abnormalities has become more important for improving risk-adapted treatment strategies in multiple myeloma (MM). However, precise cytogenetic testing by fluorescence in situ hybridization (FISH) is challenged by the dilution effect of bone marrow specimens and poor growth of plasma cells ex vivo . To address these issues, we compared the performances of three different enrichment modalities for FISH: direct FISH, fluorescence immunophenotyping and inte

Background : Epstein-Barr virus (EBV) is known to be the causative agent of infectious mononucleosis and EBV-related malignancies. In this study, we compared the results of three real-time PCR kits for EBV DNA assays.\n\nMethods : A total of 300 whole blood samples submitted for quantitative EBV PCR between January 2013 and September 2014 at Severance Hospital were included. The samples were tested by using the Artus EBV RG PCR Kit (Qiagen, Germany), AccuPower EBV Quantitative PCR Kit (Bioneer,

SJR Q1Blood

Abstract Background: Unlike dividing cells, platelets are usually regarded as unproductive in that they are anuclear fragments of megakaryocyte and incapable of the canonical cell cycle. However, recent evidence showed that platelets could form progeny or at least undergo fission. The observation indicated the existence of a non-hematopoietic mechanism to determine platelet count in peripheral blood. The assessing the kinetic aspects of platelet division is not easy because automated cell counte
