BACKGROUND: Face transplantation has naturally evolved from reconstructive procedures. However, few institutions perform face transplantations, because it is time-consuming and it is necessary to justify non-vital organ transplantation. We investigated the process of organ donation from brain-dead patients and the possibility of incorporating face transplantation into the donation process. METHODS: A retrospective review was performed of 1,074 brain-dead patients from January 2015 to December 2016 in Korea. We analyzed the time intervals from admission to brain death decisions (first, second, and final), the causes of brain death, and the state of the transplanted organs. RESULTS: The patient base (n=1,074) was composed of 747 males and 327 females. The average period between admission to the first brain death decision was 8.5 days (±15.3). The average time intervals between the first brain death decision and medical confirmation using electroencephalography and between the first brain death decision and the final determination of brain death were 16 hours 58 minutes (±14 hours 50 minutes) and 22 hours 57 minutes (±16 hours 16 minutes), respectively. The most common cause of brain death was cerebral hemorrhage/stroke (42.3%), followed by hypoxia (30.1%), and head trauma (25.2%). CONCLUSIONS: When face transplantation is performed, the transplantation team has 22 hours 57 minutes on average to prepare after the first brain death decision. The cause of brain death was head trauma in approximately one-fourth of cases. Although head trauma does not always imply facial trauma, surgeons should be aware that the facial tissue may be compromised in such cases.

Liver transplantation is a current definitive treatment for those with end-stage liver disease. Hepatic encephalopathy is a common complication of hepatic failure, which can be improved and aggravated by various causes. It is important to differentiate hepatic encephalopathy from other diseases causing brain dysfunction such as cerebral hemorrhage, which is also related to high mortality after liver transplant surgery. A 37-year-old patient was presented with acute liver failure and high ammonia levels and seizure-like symptoms. Computed tomography (CT) of his brain showed mild brain atrophy, regarded as a symptom of hepatic encephalopathy, and treated to decrease blood ammonia level. Deceased donor liver transplantation was performed and liver function and ammonia level normalized after surgery, but the patient showed symptoms of involuntary muscle contraction and showed loss of pupil reflex and fixation without recovery of consciousness. Brain CT showed brain edema and bilateral cerebral infarction, and the patient died after a few days. The purpose of this case report is to emphasize the importance of preoperative neurological evaluation, careful transplantation decision, and proper perioperative management of liver transplantation in patients with acute hepatic encephalopathy.

Stem cell therapy opens a new window in medicine to overcome several diseases that remain incurable. It appears such diseases as cardiovascular disorders, brain injury, multiple sclerosis, urinary system diseases, cartilage lesions and diabetes are curable with stem cell transplantation. However, some questions related to stem cell therapy have remained unanswered. Stem cell imaging allows approval of appropriated strategies such as selection of the type and dose of stem cell, and also mode of cell delivery before being tested in clinical trials. MRI as a non-invasive imaging modality provides proper conditions for this aim. So far, different contrast agents such as superparamagnetic or paramagnetic nanoparticles, ultrasmall superparamagnetic nanoparticles, fluorine, gadolinium and some types of reporter genes have been used for imaging of stem cells. The core subject of these studies is to investigate the survival and differentiation of stem cells, contrast agent's toxicity and long term following of transplanted cells. The promising results of in vivo and some clinical trial studies may raise hope for clinical stem cells imaging with MRI.

4.Status of Organ Donation and Solution of Organ Shortage in Korea.
The Journal of the Korean Society for Transplantation 2018;32(3):38-48
Deceased organ donation in Korea has increased steadily after legislation of transplantation law. Since last year, however, several obstacles resulting in a decrease in organ donation have been experienced. Among them, the reduced reporting of potential brain death from large size hospitals and reduced consent rate of medically available deceased donors are two main hurdles. The consent rate of organ donation was 41.9% in 2017 but has dropped to approximately 10% than 2016. Other strong family members overrode approximately 10% of donations initially consented by their next of kin. In addition to the medical points, difficulties in labor shortage are being experienced during donor management, testing and organ recovery in the hospital. Some end stage patients who are candidates as organ donor give up further management and decide to withdrawing life sustaining treatment, which deprive the chance of donation. Moreover, the national mortality rate of cerebrovascular and traffic accidents, which occupy a major part of brain death, have decreased over the recent 10 years. All of these events can cause a decrease in brain death development so it is important to find solutions to overcome all of them. Revising transplant law and donation system should be led by government. Efforts to increase the consent rate, procurement rate, and transplant rate and decrease the organ discard rate are all the responsibility of the medical team. Public awareness and a positive attitude towards organ donation are the most important basic requirements for increasing organ donation. A comprehensive task force team to overcome all of these problems is requested.

5.Factors Influencing Withdrawal of Life-Sustaining Treatment in Tertiary General Hospital Workers -Knowledge and Attitude of Organ Donation and Transplantation, Awareness of Death, Knowledge and Perception of Hospice Palliative Care-.
Korean Journal of Hospice and Palliative Care 2018;21(3):92-103
PURPOSE: This descriptive study was conducted to examine factors that affect hospital workers in their decision to withdraw from life-sustaining treatment, such as knowledge, attitude, and perception of organ donation, transplantation, death and hospice palliative care. METHODS: A questionnaire was completed by 228 workers of a tertiary general hospital, and data were analyzed using t-test, ANOVA, and Pearson's correlation by using SPSS 21.0. RESULTS: The subjects' knowledge of biomedical ethics awareness differed by age, education level, occupation, affiliated department, and biomedical ethics education. Their knowledge of brain death, organ donation and transplantation was positively correlated with attitudes toward tissue donation and transplantation, knowledge of hospice palliative care, and perception of hospice palliative care. Their attitudes toward tissue donation and transplantation were significantly correlated with knowledge of hospice palliative care, perception of hospice palliative care, and withdrawal of life-sustaining treatment. Their awareness of death was significantly correlated with knowledge of hospice palliative care, perception of hospice palliative care and withdrawal of life-sustaining treatment. The perception of hospice palliative care was significantly correlated with withdrawal of life-sustaining treatment. Factors associated with their withdrawal of life-sustaining treatment were work at the hospice ward (32.5%), attitudes toward tissue donation and transplantation and perception of hospice palliative care. CONCLUSION: This study has shown that work at the hospice ward, attitudes toward tissue donation and transplantation and perception of hospice palliative care were related to attitudes toward withdrawal of life-sustaining treatment. More research is needed to further develop various curriculums based on biomedical methods.

6.Extracorporeal Life Support in Organ Transplant Donors.
The Korean Journal of Thoracic and Cardiovascular Surgery 2018;51(5):328-332
BACKGROUND: Extracorporeal life support (ECLS) can be applied in brain-dead donors for organ perfusion before donation, thereby expanding the donor pool. The aim of this study was to examine the benefits and early clinical outcomes of ECLS for organ preservation. METHODS: Between June 2012 and April 2017, 9 patients received ECLS with therapeutic intent or for organ preservation. The following data were collected: demographics, purpose and duration of ECLS, cause of death, dose of vasoactive drugs, and need for temporary dialysis before organ retrieval. The early clinical outcomes of recipients were studied, as well as survival and graft function at 1 month. RESULTS: ECLS was initiated for extracorporeal cardiopulmonary resuscitation in 5 patients. The other patients needed ECLS due to hemodynamic deterioration during the assessment of brain death. We successfully retrieved 18 kidneys, 7 livers, and 1 heart from 9 donors. All organs were transplanted and none were discarded. Only 1 case of delayed kidney graft function was noted, and all 26 recipients were discharged without any significant complications. CONCLUSION: The benefits of protecting the vital organs of donors is significant, and ECLS for organ preservation can be widely used in the transplantation field.

PURPOSE: We investigated the clinical outcomes of deceased donor kidney transplantation (KT) using kidneys with terminal acute kidney injury (AKI). METHODS: Between February 2000 and December 2013, we performed 202 deceased donor renal transplants from 159 brain dead donors. According to the expanded criteria donor (ECD) and AKI network criteria, we divided 202 recipients into 4 groups: Group I: Non-AKI & standard criteria donor (SCD) (n = 97); group II: Non-AKI & ECD (n = 15); group III: AKI & SCD (n = 52); and group IV: AKI & ECD (n = 38). RESULTS: The incidence of delayed graft function (DFG) was significantly higher in patients with AKI than it was in the non-AKI group (P = 0.008). There were no significant differences among the 4 groups in graft survival (P = 0.074) or patient survival (P = 0.090). However, the long-term allograft survival rate was significantly lower in group IV than it was in other groups (P = 0.024). CONCLUSION: Allografts from deceased donors with terminal AKI had a higher incidence of DGF than did those from donors without AKI. However, there is no significant difference in graft and patient survival rates among the groups. So, the utilization of renal grafts from ECDs with terminal AKI is a feasible approach to address the critical organ shortage.

BACKGROUND: This retrospective study analyzed the causes of failure in the management process from the identification of brain-dead potential organ donors to actual donation in Korea over the past 5 years. METHODS: Data of 8,120 potential brain deaths reported to the Korea Organ Donation Agency were used, including information received at the time of reporting, donation suitability evaluation performed by the coordinator after the report, and data obtained from interviews of hospital medical staff and the donor's family. RESULTS: From January 2012 to December 2016, the total number of brain-dead potential organ donors in Korea was 8,120, of which 2,348 (28.9%) underwent organ procurement surgery with designated recipients. While the number of transplant donors has increased over time, the ratio of transplant donors to medically suitable brain-dead donors has decreased. The common causes of donation failure included donation refusal (27.6%), non-brain death (15.5%), and incompatible donation (11.6%); 104 potential donors (7.8%) were unable to donate their organs because they were not pronounced brain dead. CONCLUSION: The rate of successful organ donation may be increased by analyzing the major causes of failure in the brain-dead organ donation management process and engaging in various efforts to prevent such failures.

9.Immunologic Mechanism of Ischemia Reperfusion Injury in Transplantation.
The Journal of the Korean Society for Transplantation 2017;31(3):99-110
Ischemia-reperfusion injury (IRI) is an inevitable consequence of organ transplantation that has major consequences for graft-and patient survival. During transplantation procedures, allografts are exposed to various periods of complete ischemia. Ischemic insult starts with brain death, and its associated hemodynamic disturbances continue during donor organ procurement, cold preservation, and implantation. Ischemia-reperfusion injury, which is a risk factor for acute graft injury, delayed graft function, and acute and chronic rejection, is triggered following reperfusion. Along the cascade of pathogenic events that accompany ischemic insults and cause IRI, there has been an appreciation for various immune mechanisms within the allograft itself. The pathophysiological events associated with IRI originate in signals derived from pattern recognition receptors (PRRs) expressed in the donor organ. Danger associated molecular patterns (DAMP) released from injured cells serve as ligands for PRRs expressed on many cells in the donor organ. Activation of PRR signaling in the donor organ leads to production of proinflammatory cytokines and activates the innate immune system, triggering adaptive immune responses as well as cell death signaling, ultimately worsening the initial ischemic injury. Accordingly, deciphering the inflammatory pathway of innate immunity in IRI may provide a good therapeutic target to block acute sterile inflammation caused by tissue damage.

10.Affecting Factors of the Awareness of Biomedical Ethics in Nursing Students.
Journal of Korean Academic Society of Nursing Education 2017;23(4):389-397
PURPOSE: This study was conducted to examine awareness of biomedical ethics, and to identify affecting factors of the awareness of biomedical ethics in nursing students. METHODS: The subjects consisted of 266 nursing students their third and fourth years of study. The data were collected from October to December, 2015 by self-report using questionnaires. Data analysis was performed using SPSS/WIN 18.0, descriptive statistics, t-test, ANOVA, Scheffé test, Pearson correlation coefficient, and multiple regression analysis. RESULTS: The mean score of the awareness of biomedical ethics was 2.81±0.22, perception of death was 3.15±0.36, and knowledge of brain death, organ donation, and organ transplant was 12.12±3.02. The prediction factors of awareness of biomedical ethics were gender (β=.29, p<.001), participation in religious activity (β=.23, p=.015), and perception of death (β=.20, p=.016). The explanation power was 17.1%. CONCLUSION: These results showed that education about biomedical ethics is necessary for nursing students, and the development of biomedical ethics educational programs should reflect affecting factors.
