Introduction: Transfusion-transmitted infections (TTIs) pose significant public health challenges. Screening potential blood donors for hepatitis B virus (HBV), hepatitis C virus (HCV), human immunodeficiency virus (HIV), and Treponema pallidum (TP), along with ongoing monitoring of epidemiological data on TTIs among donors, is essential to ensure blood safety.
Methods: This study conducted a retrospective analysis of the seroprevalence of HBsAg, anti-HCV, anti-HIV, and anti-TP among 3,111,265 blood donation events in Guangzhou from 2014 to 2023, investigating their relationships with demographic characteristics such as gender, age, and donation status.
Results: The findings indicated that the overall seroprevalence of TTIs among blood donations was 866.21 per 100,000, demonstrating a declining trend over the ten-year period. Seroprevalence rates of transfusion-transmissible infections also exhibited a downward trend across various demographic groups. Notably, male donors, first-time donors, and older donors demonstrated higher seroprevalence rates for TTIs.
Conclusions: While the overall seroprevalence rate of transfusion-transmissible infections among blood donors remains relatively low, significant disparities exist among different demographic groups. It is necessary of sustained TTIs monitoring among blood donors to guide public health interventions and donor screening practices.

Germline DDX41 mutations (DDX41mut) are identified in approximately 5% of myeloid malignancies with excess of blasts, representing a distinct MDS/AML entity. The disease is associated with better outcomes compared to DDX41 wild-type (DDX41WT), but patients who do not undergo allogeneic hematopoietic stem cell transplantation (HSCT) may experience late relapse. Due to the recent identification of DDX41mut, data on post-HSCT outcomes remain limited.

In the event of a large-scale radiological or nuclear emergency, a rapid, high-throughput screening tool will be essential for efficient triage of potentially exposed individuals, optimizing scarce medical resources and ensuring timely care. The objective of this work was to characterize the effects of age and sex on two intracellular lymphocyte protein biomarkers, BAX and p53, for early radiation exposure classification in the human population, using an imaging flow cytometry-based platform for rapid biomarker quantification in whole blood samples. Peripheral blood samples from male and female donors, across three adult age groups (young adult, middle-aged, senior) and a juvenile cohort, were X-irradiated (0-5 Gy), and biomarker expression was quantified at two- and three-days post-exposure.

B cells are critical components of the adaptive immune system that proliferate and differentiate within the secondary lymphoid organs upon recognition of antigens and engagement of T cells. Traditional two-dimensional (2D) cell cultures fall short of replicating the intricate structures and dynamic evolution of three-dimensional (3D) environments found in lymphoid organs, prompting the development of more physiologically pertinent models. Our approach employs -hexanoyl glycol chitosan (HGC) coated ultra-low attachment (ULA) lattice plates to cultivate a 3D co-culture of CD40L-expressing MS5 stromal cells and naïve B cells derived from the peripheral blood mononuclear cells (PBMCs) of healthy human donors.

Background: Inflammatory injury in organ donors, particularly after brain death and during ischemia-reperfusion, contributes to graft dysfunction, rejection, and reduced survival. Statins, beyond their lipid-lowering role, exert pleiotropic anti-inflammatory and immunomodulatory effects, including IL-6 suppression, NF-κB inhibition, immune cell modulation, and potential alteration of exosome secretion.
Methods: Building upon this background, this narrative review synthesises preclinical and clinical evidence on pre-donation statin therapy in solid organ transplantation.

In the United States, the use of Food & Drug Administration (FDA)-licensed, approved, or cleared tests is required for infectious disease screening and determining the eligibility of deceased donors for all Human Cells, Tissues, and Cellular and Tissue-Based Products (HCT/Ps). With the discontinuation of two manual enzyme-linked immunoassay (EIA) tests, automated Chemiluminescent Microparticle Immunoassay (CMIA) technology was introduced as the primary alternative. This study compares serologic reactivity rates between manual EIA and automated CMIA methods.
