研究室紹介
Professor You Hwan Jo's research lab specializes in critical care medicine and emergency medicine, with a focus on early detection and prognostic assessment in acute conditions such as sepsis, stroke, and vertebral compression fractures. The lab investigates biomarkers like monocyte and phosphate levels, as well as advanced monitoring technologies such as near-infrared spectroscopy (fNIRS) for real-time hemodynamic assessment. Key research directions include improving risk stratification tools—such as the DEWS score—for rapid response systems and evaluating the impact of acute conditions on patient outcomes. The lab also explores non-invasive anesthetic and sedation strategies in pediatric critical care.

15This study was performed to evaluate the association of monocyte counts with mortality, the rate of bacteremia, and organ dysfunction and to evaluate whether the change in monocyte counts from the premorbid state to sepsis would differ between survivors and non-survivors in patients with severe sepsis including septic shock. A retrospective analysis of patients with severe sepsis including septic shock was performed. Monocyte counts were categorized into <250, 250-500, 500-750, and ≥750 cells/μL
Our study showed that DEWS was superior to MEWS in three key aspects (IHCA predictive, alarming, and timeliness performance). This study demonstrates the potential of DEWS as an effective, efficient screening tool in rapid response systems (RRSs) to identify high-risk patients.
Nitrous oxide inhalation was preferable to injectable ketamine for pediatric patients because it is safe, allows for a faster recovery, maintains sufficient sedation time, and does not induce unnecessarily deep sedation.
BACKGROUND: Ischaemic tissue injury caused by tissue hypoperfusion is one of the major consequences of sepsis. Phosphate concentrations are elevated in ischaemic tissue injury. This study was performed to investigate the association of phosphate concentrations with mortality in patients with sepsis. METHODS: This was a retrospective cohort study of patients with sepsis conducted at an urban, tertiary care emergency department (ED) in Korea. Patients with sepsis arriving between March 2010 and Ap
STUDY DESIGN: Retrospective large population-based study. OBJECTIVE: The aim of this study is to elucidate the association between vertebral compression fractures (VCFs) and pneumonia. SUMMARY OF BACKGROUND DATA: VCF is known to be associated with impaired pulmonary function. However, the risk of developing pneumonia after new-onset VCF has not been evaluated. METHODS: The data source was the National Health Screening Program Cohort, a population-based sample cohort of national health screening
<b>Background:</b> NIRSIT, a functional near-infrared spectroscopy (fNIRS) device with 204 channels, can measure oxyhemoglobin (HbO2) and deoxyhemoglobin (HbR) in non-pulsatile blood flow non-invasively using the absorption difference between HbO2 and HbR at a wavelength of 700-1,000 nm and can display the perfusion status in real time. <b>Objective:</b> We applied NIRSIT to patients with stroke to evaluate the usefulness of NIRSIT as an fNIRS device for the early detection of stroke. <b>Methods
BACKGROUND: Conventional cardiopulmonary resuscitation (CPR) training for the general public involves the use of a manikin and a training video, which has limitations related to a lack of realism and immersion. To overcome these limitations, virtual reality and extended reality technologies are being used in the field of medical education. The aim of this study is to explore the efficacy and safety of extended reality (XR)-based basic life support (BLS) training. METHODS: This study is a prospec
