Objective: There is controversial evidence on a matrix influence on the measurement of NT-proBNP.
Design And Methods: We compared results of Elecsys NT-proBNP measurement on serum, K2 EDTA plasma and lithium heparin plasma.
Results: Samples collected in K2 EDTA showed a marginally significant underestimation when compared to serum and heparin, whereas no significant difference was observed between serum and heparin plasma.
Conclusions: Serum, heparin and K2 EDTA plasma may be suitable for NT-proBNP measurement.

Heparin-induced thrombocytopenia requiring VA-ECMO management during percutaneous coronary intervention for acute coronary syndrome: A case report.
J Cardiol Cases

Department of Cardiovascular Medicine, Okayama City Hospital, Okayama, Japan.
Unlabelled: Heparin-induced thrombocytopenia (HIT) is an immune-mediated disease with severe thromboembolic complications. HIT during percutaneous coronary intervention (PCI) can be fatal without prompt treatment. We report an unusual case of HIT observed during PCI for acute coronary syndrome (ACS).

Methods: In this study, we used cytometric bead array (CBA) and chemiluminescence (ECL). These two methods were used to test serum and plasma samples from 50 healthy adult volunteers and 50 rheumatoid arthritis (RA) patients' cytokine levels.
Inflammatory Monocyte Subsets Correlation with Iron Levels in Low Vitamin D Pediatric Transfusion-Dependent Thalassemia.
J Inflamm Res

Department of Biomedical Sciences, Faculty of Medicine, Universitas Padjadjaran, Bandung, West Java, 45363, Indonesia.
Background: Patients with transfusion-dependent thalassemia experience iron dysregulation, which affects the immune response. Surface proteins such as FcγRIII (CD16), lipopolysaccharide receptor (CD14), and human leukocyte antigen (HLA-DR) on monocytes are crucial for innate and adaptive responses. Blood monocytes, identified by their CD14 and CD16 expression, show functional diversity during injury or inflammation.

Objective: To evaluate the predictive value of plasma heparin-binding protein (HBP) combined with albumin (Alb) for predicting 28-day mortality in patients with sepsis.
Methods: The clinical data of patients with sepsis admitted to the emergency intensive care unit (EICU) of the People's Hospital of Shenzhen Baoan District from March 2020 to March 2024 were retrospectively analyzed. The study began at the time of the first diagnosis of sepsis upon EICU admission and ended upon patient death or at 28 days.
