Introduction: Recent guidelines recommend restrictive red blood cell transfusion; therefore, hospitals have started introducing and implementing patient blood management programs. This is the first study to analyze changes in the trends of blood transfusions in the whole population over the past 10 years according to sex, age group, blood component, disease, and hospital type.
Methods: This cohort study analyzed blood transfusion records for 10 years, from January 2009 to December 2018, using nationwide population-based data from the Korean National Health Insurance Service-Health Screening Cohort database.
Results: The proportion of transfusion procedures conducted in the total population has increased constantly for 10 years. Although its proportion in the age group of 10-79 years decreased, the total number of transfusions increased significantly due to the increase in the population and proportion of transfusions in those aged 80 years or older. Furthermore, the proportion of multicomponent transfusion procedures increased in this age group, which was greater than that of transfusions. The most common disease among transfusion patients in 2009 was cancer, of which gastrointestinal (GI) cancer accounted for more than half, followed by trauma and hematologic diseases (GI cancers > trauma > other cancers > hematologic diseases). The proportion of patients with GI cancer decreased, whereas that of trauma and hematologic diseases increased over the 10 years, with trauma becoming the most common disease type in 2018 (trauma > GI cancers > hematologic diseases > other cancers). Although transfusion rates per hospitalization decreased, the total number of inpatients increased, thus increasing the number of blood transfusions in all types of hospitals.
Discussion/conclusions: The proportion of transfusion procedures in the total population increased owing to the increase in the total number of transfusions in patients aged 80 years or older. The proportion of patients with trauma and hematologic diseases has also increased. Moreover, the total number of inpatients has been increasing, which subsequently increases the number of blood transfusions performed. Specific management strategies targeting these groups may improve blood management.

Background: The challenges associated with traditional drug screening, such as high costs and long screening times, have led to an increase in the use of single-cell isolation technologies. Small sample volumes are required for high-throughput, cell-based assays to reduce assay costs and enable rapid sample processing. Using microfluidic chips, single-cell analysis can be conducted more effectively, requiring fewer reagents and maintaining biocompatibility.

IKKα, encoded by CHUK, is crucial in the non-canonical NF-κB pathway and part of the IKK complex activating the canonical pathway alongside IKKβ. The absence of IKKα causes fetal encasement syndrome in humans, fatal in utero, while an impaired IKKα-NIK interaction was reported in a single patient and causes combined immunodeficiency. Here, we describe compound heterozygous variants in the kinase domain of IKKα in a female patient with hypogammaglobulinemia, recurrent lung infections, and Hay-Wells syndrome-like features.

Background: Low-dose (LD) or intermediate-dose (MD) immune tolerance induction (ITI) is effective in children with severe hemophilia A (SHA) with high-titer inhibitors (HTIs) and is attractive in countries with economic constraints. However, high-quality evidence of their use is lacking.
Objectives: This was a multicenter randomized clinical trial comparing the efficacy, safety, and medication cost between LD-ITI and MD-ITI for SHA-HTI children.
