Professor Ju-Hyun Song's research lab specializes in critical care biomarkers and prognostic indicators in sepsis and acute infectious diseases. The lab focuses on identifying and validating novel biomarkers—such as IL-6, PTX3, presepsin, procalcitonin, lactate, and hemodynamic scores like VISmax—to improve early diagnosis, risk stratification, and outcome prediction in sepsis and septic shock. Their work integrates clinical immunology, emergency medicine, and biostatistical modeling to enhance patient management under the Sepsis-3 definitions. The lab also investigates clinical outcomes in emerging infectious diseases, including COVID-19, with a strong emphasis on real-world data and translational research.

15BACKGROUND: This study investigated the clinical value of interleukin-6 (IL-6), pentraxin 3 (PTX3), and procalcitonin (PCT) in patients with sepsis and septic shock diagnosed according to the Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3). METHODS: Serum levels of IL-6, PTX3, and PCT were measured in 142 enrolled subjects (51 with sepsis, 46 with septic shock, and 45 as controls). Follow-up IL-6 and PTX3 levels were measured in patients with initial septic shock
BACKGROUND: We investigated the diagnostic and prognostic value of presepsin among patients with organ failure, including sepsis, in accordance with the Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3). METHODS: This prospective observational study included 420 patients divided into three groups: non-infectious organ failure (n = 142), sepsis (n = 141), and septic shock (n = 137). Optimal cut-off values of presepsin to discriminate between the three groups were ev
ABSTRACT: The 2016 Surviving Sepsis Campaign guidelines suggest guiding resuscitation to normalize lactate levels in patients with sepsis-associated hyperlactatemia as a marker of tissue hypoperfusion. This study evaluated the prognostic value of lactate levels and lactate clearance for 30-day mortality in patients with sepsis and septic shock diagnosed in the emergency department.We performed a retrospective cohort study of sepsis patients with initial lactate levels of ≥2 mmol/L. All patients
Biomarkers are valuable tools for the prediction of mortality in patients with sepsis. However, the use of a single biomarker to predict patient outcomes is challenging owing to the complexity and redundancy of the immune response to infections.We aimed to conduct a prospective observational analysis to investigate the prognostic value of pentraxin 3, interleukin 6, procalcitonin, and lactate combined in predicting the 28-day mortality rate in patients with sepsis or septic shock (n = 160; sepsi
Vasoactive and inotropic medications are essential for sepsis management; however, the association between the maximum Vasoactive-Inotropic score (VISmax) and clinical outcomes is unknown in adult patients with sepsis. We investigated the VISmax as a predictor for mortality among such patients in the emergency department (ED) and compared its prognostic value with that of the sequential organ failure assessment (SOFA) score. This single-center retrospective study included 910 patients diagnosed
We investigated association between epidemiological and clinical characteristics of coronavirus disease 2019 (COVID-19) patients and clinical outcomes in Korea. This nationwide retrospective cohort study included 5621 discharged patients with COVID-19, extracted from the Korea Disease Control and Prevention Agency (KDCA) database. We compared clinical data between survivors (n = 5387) and non-survivors (n = 234). We used logistic regression analysis and Cox proportional hazards model to explore
We developed a novel computer program, the Intelligent Sepsis Management System, based on Sepsis-3 definitions and 2016 Surviving Sepsis Campaign guidelines and performed a quasi-experimental pre-post study to assess its effect on compliance with the Surviving Sepsis Campaign guidelines and outcomes in patients with sepsis and septic shock. During the pre-period, patients were managed with usual care. During the post-period, patients were managed using the Intelligent Sepsis Management System up
Abstract The instability of zinc metal anodes, including dendrite formation and corrosion, limits their application in aqueous zinc‐ion batteries (AZIBs). Here, a near‐single zinc‐ion conducting (NSIC) protective layer that enables dendrite‐free Zn anodes by integrating Zn 2 ⁺‐conducting polymer matrices with counter‐anion trapping agents is presented. Sulfonic acid groups, covalently bonded to polymeric backbones enhance Zn 2 ⁺ ion mobility while counter‐anions are immobilized by amine‐function

In the PSM cohort, women with OHCA underwent CAG and PCI less frequently than men, regardless of the initial rhythm. However, these sex-related differences narrowed with increasing age. Further studies are needed to confirm the sex-related disparities in the in-hospital management of patients with OHCA.
Traumatic brain injury (TBI) is a significant healthcare concern in several countries, accounting for a major burden of morbidity, mortality, disability, and socioeconomic losses. Although conventional prognostic models for patients with TBI have been validated, their performance has been limited. Therefore, we aimed to construct machine learning (ML) models to predict the clinical outcomes in adult patients with isolated TBI in Asian countries. The Pan-Asian Trauma Outcome Study registry was us
As delayed treatment of septic shock can lead to an irreversible health state, timely identification of septic shock holds immense value. While numerous approaches have been proposed to build early warning systems, these approaches primarily focus on predicting the future risk of septic shock, irrespective of its precise onset timing. Such early prediction systems without consideration of timeliness fall short in assisting clinicians in taking proactive measures. To address this limitation, we e
