Beyond prothrombin time and activated partial thromboplastin time: coagulation in vivo—an illustrated review
Neil S Harris and others
The steps that initiate coagulation in vivo are different from the components of prothrombin time (PT) and activated partial thromboplastin time (aPTT). The reactions of PT and aPTT are kept separate by the addition of high concentrations of tissue factor (for PT) or silica (for aPTT). In vivo, ...
Longstanding, undiagnosed, highly replicative hepatitis B virus reactivation in the presence of high levels of anti-HBs antibodies
Mahdi Ouafi and others
Introduction Kidney transplant recipients are among the populations at risk for Hepatitis B Virus (HBV) reactivation, and close monitoring is needed for its early detection. Methods We describe a case of HBV reactivation in a patient who underwent kidney transplantation more than 30 years ago, with ...
The value of HE4 and its combined detection on predicting recurrence and cancer death in patients with non–small cell lung cancer
Xiaojie Zheng and others
Introduction Human epididymis protein 4 (HE4), a potential novel biomarker for cancers, has been widely used in clinical practice, but evidence of its prognostic value for non–small cell lung cancer (NSCLC) remain insufficient. This study aimed to explore the predictive value of serum HE4 levels on ...
New formula based on the discrepancy between impedance and fluorescence platelet to distinguish iron-deficiency anemia from non–transfusion-dependent thalassemia
Chanjuan Wang and others
Introduction Iron-deficiency anemia (IDA) and non–transfusion-dependent thalassemia (NTDT) are the 2 most common types of microcytic hypochromic anemia, but they are difficult to distinguish by routine tests. It is reported that red blood cells (RBCs) in thalassemia tend to be more microcytic and ...
Hsa-miR-2113-5p is not a key indicator for coronary artery disease: a case-controlled observational study
Meisam Rostaminasab Dolatabad and others
Introduction Coronary artery disease (CAD) is a prevalent inflammatory disease. Interferon λ 1 (IFN-λ1) is a known factor that participates in the pathogenesis of proinflammatory diseases, but the roles of IFN-λ1 in CAD and its regulators have yet to be clarified. Bioinformatic analysis revealed ...
Investigating discrepancies and false positives in immunohematology tests using gel cards: insights from a case study on antibodies targeting the gel card matrix
Deerej P and others
Introduction Discrepancies in gel card immunohematologic testing can result in false-positive reactions, making detecting antibodies and performing crossmatching difficult. Such unexpected reactivity may result from interactions with test system components, including the column matrix, chemicals, ...
Genetic variations in pseudoachondroplasia: a review of case reports
Lukasz Petryka and Michal Ordak
Introduction Pseudoachondroplasia is a rare and severe genetic disorder caused by a mutation in the COMP gene, making precise molecular diagnosis crucial for effective treatment. In the literature, case reports of patients with pseudoachondroplasia have consistently described novel mutations in the ...
Expedited response to unsafe conditions: an academic health system approach
Corey Peng and others
Introduction The Clinical Laboratory Improvement Amendments require nonconforming safety event identification, targeted intervention, and evaluation of interventional effectiveness. Without a standardized reporting structure, risk and safety teams will experience ongoing challenges with situational ...
Optimized efficient screening for Duchenne muscular dystrophy carriers using proto-oncogene tyrosine-protein kinase receptor Ret
Dongyang Hong and others
Introduction Duchenne muscular dystrophy (DMD) is a severe genetic disorder affecting 5% to 19% of carriers. Creatine kinase (CK) is a traditional biomarker for DMD, but its screening accuracy is limited. This study evaluated the potential of combining the proto-oncogene tyrosine-protein kinase ...
Coexistence of antinucleosome and anti–double-stranded DNA antibodies is associated with severe systemic lupus erythematosus in Tunisian patients
Mourad Elghali and others
Introduction We sought to compare clinical features among distinct antibody profiles defined by the presence or absence of antinucleosome (anti-NCS) and anti–double-stranded DNA (anti-dsDNA) antibodies in Tunisian patients with systemic lupus erythematosus (SLE). Methods The study enrolled 131 ...
