Utility of arterial to end-tidal carbon dioxide gradient as a severity index in critical care.

Background: The arterial to end-tidal carbon dioxide gradient (P [a-Et] CO) reveals the ventilation-perfusion (V/Q) status of critically ill patients. V/Q mismatch has several causes and affects the clinical outcomes of critically ill patients. We investigated the relationship between P (a-Et) CO and the clinical outcomes in critically ill patients.

Impact of nutrition-related laboratory tests on mortality of patients who are critically ill using artificial intelligence: A focus on trace elements, vitamins, and cholesterol.

Background: This study aimed to understand the collective impact of trace elements, vitamins, cholesterol, and prealbumin on patient outcomes in the intensive care unit (ICU) using an advanced artificial intelligence (AI) model for mortality prediction.

Methods: Data from ICU patients (December 2016 to December 2021), including serum levels of trace elements, vitamins, cholesterol, and prealbumin, were retrospectively analyzed using AI models. Models employed included category boosting (CatBoost), extreme gradient boosting (XGBoost), light gradient boosting machine (LGBM), and multilayer perceptron (MLP).

Analysis of hemodynamics and impedance using bioelectrical impedance analysis in hypovolemic shock-induced swine model.

To treat hypovolemic shock, fluid infusion or blood transfusion is essential to address insufficient volume. Much controversy surrounds resuscitation in hypovolemic shock. We aimed to identify the ideal fluid combination for treating hypovolemic shock-induced swine model, analyzing bioelectrical impedance and hemodynamics.

Tibial-sided Anterolateral Ligament Injuries Are Associated With Poor Healing and Residual Pivot Shift Testing After Anterior Cruciate Ligament Reconstruction.

Purpose: To investigate whether tibial-sided anterolateral ligament (ALL) injuries are associated with poor healing and residual pivot shift.

Methods: Patients who underwent anterior cruciate ligament reconstructions within postinjury 6 weeks from January 2008 to March 2021 were included. They had concomitant ALL injury confirmed by preoperative magnetic resonance imaging (MRI) and were followed for a minimum of 20 months.

Liver Transplantation from Brain-Dead Donors with Hepatitis B or C in South Korea: A 2014-2020 Korean Organ Transplantation Registry Data Analysis.

BACKGROUND According to the current guidelines for liver transplantation (LT) of brain-dead donors with hepatitis B or C virus (HBV or HCV) in Korea, grafts from hepatitis B surface antigen (HBsAg)(+) or HCV antibody (anti-HCV)(+) donors must be transplanted only to HBsAg(+) or anti-HCV(+) recipients, respectively. We aimed to determine the current status and outcomes of brain-dead donor LT with HBV or HCV in Korea. MATERIAL AND METHODS This retrospective observational study included all LTs from brain-dead donors in the Korean Organ Transplantation Registry between April 2014 and December 2020.

Kidney Transplantation From Brain-Dead Donors With Hepatitis B or C in South Korea: A 2015 to 2020 Korean Organ Transplantation Registry Data Analysis.

Background: According to the current Center for Korean Network for Organ Sharing guidelines for kidney transplantation from brain-dead donors with hepatitis B or C infection, organs from hepatitis B surface antigen-positive (HbsAg) or anti-hepatitis C virus-positive (HCV) donors can only be transplanted into HBsAg or anti-HCV recipients. We aimed to confirm the status and the outcomes of kidney transplantation from brain-dead donors with hepatitis B or C virus in Korea.

Methods: This retrospective study included all kidney transplantations from brain-dead donors in the Korean Organ Transplantation Registry database between January 2015 and June 2020, divided into 3 groups according to donor hepatitis status.

Organ donation after controlled circulatory death (Maastricht classification III) following the withdrawal of life-sustaining treatment in Korea: a suggested guideline.

The "Act on hospice and palliative care and decisions on life-sustaining treatment for patients at the end of life" was enacted in February 2018 in Korea. Therefore, we suggest a Korean guideline for organ donation after circulatory death (DCD) category III after the withdrawal of life-sustaining treatment (WLST). Implementation of WLST includes stopping ventilation, extubation, discontinuation of inotropics and vasoconstrictors, cessation of continuous renal replacement therapy, and cessation of extracorporeal membrane oxygenation.

First Organ Donation after Circulatory Death Following Withdrawal of Life-sustaining Treatment in Korea: a Case Report.

In February 2018, the Withdrawal of the Life-sustaining Treatment (WLST) Decision Act was legalized in Korea. Donation after circulatory death (DCD) after WLST was classified as DCD category III. We report the first case of successful organ donation after WLST in Korea.

Organ Donation from Donors with Hepatitis B or C in South Korea: A 2013-2017 Nationwide Data Analysis.

BACKGROUND The number of organ donations from hepatitis B virus (HBV) or hepatitis C virus (HCV)-positive donors is gradually increasing; however, the current status of organ donation from brain-dead donors with hepatitis in South Korea has not been analyzed. This study aimed to analyze this. MATERIAL AND METHODS In total, 9210 potential brain deaths were reported in South Korea from January 2013 to December 2017, of which 333 were hepatitis carriers (HBV, n=246; HCV, n=87).
