Currently, no effective therapy and potential target have been elucidated for preventing myocardial ischemia and reperfusion injury (I/R). We hypothesized that the administration of recombinant klotho (rKL) protein could attenuate the sterile inflammation in peri-infarct regions by inhibiting the extracellular release of high mobility group box-1 (HMGB1). This hypothesis was examined using a rat coronary artery ligation model. Rats were divided into sham, sham+ rKL, I/R, and I/R+ rKL groups (n =

BACKGROUND: With an aging population, the number of elderly individuals exposed to traumatic injuries is increasing. The elderly age criterion for traumatic injuries has been inconsistent in the literature. This study aimed at specifying the elderly age criterion when the traumatic mortality rate increases. METHODS: This is a multicenter retrospective cohort study that was conducted utilizing the data from the Emergency Department-based Injury In-depth Surveillance Registry of the Korea Disease

<b>Objectives:</b> The food delivery market is growing rapidly. As most delivery riders use motorcycles, motorcycle crashes will increase along with the growing delivery market size. This study aimed at examining the proportions of motorcycle crashes and characteristics of injuries incurred while using motorcycles for occupational purposes.<b>Methods:</b> This retrospective analysis included motorcycle crash patients aged 16 years or older, who were treated in 23 emergency rooms in Korea, betwee

The triage process in emergency departments (EDs) relies on the subjective assessment of medical practitioners, making it unreliable in certain aspects. There is a need for a more accurate and objective algorithm to determine the urgency of patients. This paper explores the application of advanced data-synthesis algorithms, machine learning (ML) algorithms, and ensemble models to predict patient mortality. Patients predicted to be at risk of mortality are in a highly critical condition, signifyi

Patients with low baseline renal function had the highest incidence of postcontrast acute kidney injury after CTA and cerebral angiography, but no fatal adverse effects were documented. Thus, patients suspected of having a stroke should be actively managed with respect to neurovascular function.

BACKGROUND AND IMPORTANCE: Appropriate decision-making is critical for transfusions to prevent unnecessary adverse outcomes; however, transfusion in the emergency department (ED) can only be decided based on sparse evidence in a limited time window. OBJECTIVES: This study aimed to identify factors associated with appropriate red blood cell (RBC) transfusion in the ED by analyzing retrospective data of patients who received transfusions at a single center. OUTCOME MEASURES AND ANALYSIS: This stud

Background Red blood cell transfusion is frequently prescribed in the emergency department for patients with gastrointestinal bleeding (GIB), but the association of time to transfusion with patient outcome has not been thoroughly evaluated.Methods A retrospective cohort study analyzed adult patient data with GIB who visited the emergency department of single university-affiliated hospital between January 2016 and April 2022. The associations of time to transfusion and patient outcomes, 30-day an

OBJECTIVE: This study aimed to introduce a novel negative pressure aerosol box (Carrycure Isolator) and to test its efficiency and limitations, with the hope of suggesting improvements and further directions. METHODS: A novel aerosol box (Carrycure Isolator) was invented. A single-center, randomized, crossover simulation study of 28 emergency medicine physicians was designed. Three trials of each participant using an intubation manikin were conducted, including intubation without the aerosol box

OBJECTIVE: The efficacy of previously developed respiratory barrier enclosures to limit healthcare workers' exposure to aerosols from COVID-19 patients remains unclear; in addition, the design of these devices is unsuitable for transportation or other emergency procedures. Therefore, we developed a novel negative pressure respiratory isolator to improve protection from patient-generated aerosols and evaluated its protective effect in conversion to systemic isolator. METHODS: This in vitro study

OBJECTIVE: Emergency department (ED) triage systems are used to classify the severity and urgency of emergency patients, and Korean medical institutions use the Korean Triage and Acuity Scale (KTAS). During the COVID-19 pandemic, appropriate treatment for emergency patients was delayed due to various circumstances, such as overcrowding of EDs, lack of medical workforce resources, and increased workload on medical staff. The purpose of this study was to evaluate the accuracy of the KTAS in predic

The effect of the duration of red blood cell (RBC) storage on the outcomes of transfused patients remains controversial, and studies on patients in the emergency department (ED) are limited. This study aimed to determine the association between RBC storage duration and outcomes of patients receiving transfusions in the ED. For RBCs issued to patients in the ED between 2017 and 2022, the storage period of the RBC and data on the transfused patient were obtained. Patients were divided into fresh (

Red blood cell (RBC) transfusion is frequently administered to patients after cardiac arrest; however, its association with patient outcomes has not been well established. This study investigated the association between early RBC transfusion after the return of spontaneous circulation (ROSC) and patient outcomes in adults with cardiac arrest. We analyzed data from 586 adult patients who achieved ROSC at two university-affiliated hospitals in Korea between August 2014 and December 2023. Early tra

ABSTRACT Background Objective Structured Clinical Examination (OSCE; Clinical Performance Examination [CPX] in South Korea) is a high-stakes assessment of clinical performance, communication, and reasoning during time-limited patient encounters. As AI-enabled virtual standardized patient (VSP) simulation and automated scoring are introduced for OSCE-like training, prospective evidence is needed on how such systems perform and are perceived when embedded in real educational workflows.
