Intraindividual Comparison of Image Quality Between Low-Dose and Ultra-Low-Dose Abdominal CT With Deep Learning Reconstruction and Standard-Dose Abdominal CT Using Dual-Split Scan.

Objective: The aim of this study was to intraindividually compare the conspicuity of focal liver lesions (FLLs) between low- and ultra-low-dose computed tomography (CT) with deep learning reconstruction (DLR) and standard-dose CT with model-based iterative reconstruction (MBIR) from a single CT using dual-split scan in patients with suspected liver metastasis via a noninferiority design.

Materials And Methods: This prospective study enrolled participants who met the eligibility criteria at 2 tertiary hospitals in South Korea from June 2022 to January 2023. The criteria included (a) being aged between 20 and 85 years and (b) having suspected or known liver metastases.

The role of different health information sources in moderating the impact of health literacy on health-related quality of life: evidence from a population-based study in Korea.

Purpose: Health literacy is a key aspect of healthy living and is widely recognized as a crucial determinant of health outcomes and disparities. Health literacy enables individuals to make informed decisions by accessing, understanding, and utilizing health-related information effectively. Access to and use of health information are essential for optimal health outcomes.

An IgM Cleaving Enzyme for Clearance of Anti-Pig Xenoreactive Antibodies in a Nonhuman Primate Model.

Background: The removal of preformed antibodies with cleaving enzyme like IdeS (Imlifidase) has demonstrated therapeutic potential in organ transplantation for sensitized recipients. However, preformed xenoreactive antibodies (XAbs) against porcine glycans are predominantly IgM and considered detrimental in pig-to-human xenotransplantation.

Methods: Recombinant IceM, an endopeptidase cleaving IgM, was generated in Escherichia coli.

Multicenter validation of secondary hemophagocytic lymphohistiocytosis diagnostic criteria.

Background: Five fulfilled hemophagocytic lymphohistiocytosis (HLH)-2004 criteria, and the HScore are widely used and recommended by international expert consensus to diagnose secondary HLH. Both diagnostic scores have never been validated in heterogeneous patient cohorts of secondary HLH patients. We aimed to systematically optimize and validate diagnostic criteria of secondary HLH using a multicenter approach.
