"Brain death"

BACKGROUND: No reports of organ donation have been documented in patients suffering from severe autoimmune glial fibrillary acidic protein (GFAP) astrocytopathy. CASE PRESENTATION: A 27-year-old male patient developed a fever and headache, followed a week later by weakness and unsteadiness in his limbs. He attended his local hospital, but no cause was found. Thirteen days later, he became unconscious and was promptly moved to the intensive care unit for symptomatic support treatment, with no improvement...

BACKGROUND: Hypoxemia is the main modifiable factor preventing lungs from being transplanted from organ donors after brain death. One major contributor to impaired oxygenation in patients with brain injury is atelectasis. Apnea testing, an integral component of brain death declaration, promotes atelectasis and can worsen hypoxemia. In this study, we tested whether performing a recruitment maneuver (RM) after apnea testing could mitigate hypoxemia and atelectasis. METHODS: During the study period, an RM (positive end-expiratory pressure of 15 cm H2 O for 15 s then 30 cm H2 O for 30 s) was performed immediately after apnea testing...

BACKGROUND: Liver transplantation (LT) is crucial for end-stage liver disease patients, but organ shortages persist. Donation after circulatory death (DCD) aims to broaden the donor pool but presents challenges. Complications like acute rejection, hepatic artery thrombosis, and biliary issues still impact posttransplant prognosis. Biomarkers, including extracellular vesicles (EVs) and microRNAs (miRNAs), show promise in understanding and monitoring posttransplant events. This study explores the role of EVs and their miRNA cargo in LT, including their potential as diagnostic tools...

BACKGROUND: Donation after circulatory death (DCD) heart transplantation (HTx) significantly expands the donor pool and reduces waitlist mortality. However, high-level evidence-based data on its safety and effectiveness are lacking. This meta-analysis aimed to compare the outcomes between DCD and donation after brain death (DBD) HTxs. METHODS: Databases, including MEDLINE, Embase, CINAHL, and the Cochrane Central Register of Controlled Trials, were systematically searched for randomized controlled trials and observational studies reporting the outcomes of DCD and DBD HTxs published from 2014 onward...

Jordan performed the Middle East's first living-donor kidney transplant in 1972. In 1977, the country became one of the first Arab countries to regulate organ donation and transplantation. Despite these early advances in living donor transplantation, Jordan's organ donation after brain death program remains inactive, making it challenging to meet organ demand and placing many patients on long transplant waiting lists. As of 2020, only 14.2% of the patients with end-stage kidney disease have access to a living donor...

BACKGROUND: Prolonged donor hepatectomy time may be implicated in early and late complications of liver transplantation. AIM: To evaluate the impact of donor hepatectomy time on outcomes of liver transplant recipients, mainly early allograft dysfunction. METHODS: This multicenter retrospective study included brain-dead donors and adult liver graft recipients. Donor-recipient matching was obtained through a crossover list. Clinical and laboratory data were recorded for both donors and recipients...

A 49-year-old female patient presented at the hospital with a history of herpetic blisters, frequent episodes of vomiting and loose stools, bilateral upper and lower limb weakness, and diminishing sensorium. She was diagnosed with hyponatraemia and respiratory failure and later became unconscious with absent brainstem reflexes. The patient was initially treated for herpetic encephalitis, a chronic obstructive pulmonary disease with acute exacerbation, hyponatraemia and neuroparalytic snake bite. Further evaluation, however, identified the uncommon Guillain Barre syndrome presentation with overlap of Bickerstaff brainstem encephalitis...

BACKGROUND: Obtaining organs for transplants through a deceased donor occurs exclusively through donation. However, some open protocols with potential donors do not become effective donors due to medical refusal. Our aim was to identify the profile of non-donors of organs and tissues due to medical refusal in a state reference service for transplants. METHODS: This is a cross-sectional study with retrospective data collection from medical records of patients who died and had a protocol opened to evaluate brain death and procurement of organs and tissues in 2019...

Experimental models are important tools for understanding the etiological phenomena involved in various pathophysiological events. In this context, different animal models are used to study the elements triggering the pathophysiology of primary graft dysfunction after transplantation to evaluate potential treatments. Currently, we can divide experimental donation models into two large groups: donation after brain death and donation after circulatory arrest. In addition, the deleterious effects associated with hemorrhagic shock should be considered when considering animal models of organ donation...

BACKGROUND: The medical students' knowledge and attitude toward brain death has not been investigated in China. The aims of this study were to assess the knowledge and attitude toward brain death among medical students in China and assess the influence of medical education on the knowledge and attitude. METHODS: An online questionnaire consisting of 17 questions was developed and completed by undergraduates majoring in clinical medicine in China Medical University...

BACKGROUND: Donation after circulatory death (DCD) has reemerged as a method of expanding the donor heart pool. Given the high waitlist mortality of multiorgan heart candidates, we evaluated waitlist outcomes associated with willingness to consider DCD offers and post-transplant outcomes following DCD transplant for these candidates. METHODS: Using the United Network for Organ Sharing database, we identified adult multiorgan heart candidates and recipients between 1/1/2020 and 3/31/2023...

OBJECTIVE: The aim of this study is to describe the results of Spanish ICUs in ETHICUS II study. DESIGN: Planned substudy of patients from ETHICUS II study. SETTING: 12 Spanish ICU. PATIENTS OR PARTICIPANTS: Patients admitted to Spanish ICU who died or in whom a limitation of life-sustaining treatment (LLST) was decided during a recruitment period of 6 months. INTERVENTIONS: Follow-up of patients was performed until discharge from the ICU and 2 months after the decision of LLST or death...

The controversy over the equivalence of continuous sedation until death (CSD) and physician-assisted suicide/euthanasia (PAS/E) provides an opportunity to focus on a significant extended use of CSD. This extension, suggested by the equivalence of PAS/E and CSD, is designed to promote additional patient autonomy at the end-of-life. Samuel LiPuma, in his article, "Continuous Sedation Until Death as Physician-Assisted Suicide/Euthanasia: A Conceptual Analysis" claims equivalence between CSD and death; his paper is seminal in the equivalency debate...

Donation after circulatory death(DCD) could account for the largest expansion of the donor allograft pool in the contemporary era. However, the organ yield and associated costs of Normothermic Regional Perfusion(NRP) compared to Super-Rapid Recovery(SRR) with ex-situ Normothermic Machine Perfusion(NMP), remain unreported. The Organ Procurement and Transplantation Network (December 2019-June 2023) was analyzed to determine the number of organs recovered per donor. A cost analysis was performed based on our institution's experience since 2022...

BACKGROUND & AIMS: The National Liver Offering Scheme (NLOS) was introduced in the UK in 2018 to offer livers from deceased donors to patients on the national waiting list based, for most patients, on calculated transplant benefit. Before NLOS, livers were offered to transplant centres by geographic donor zones and, within centres, by estimated recipient need for a transplant. METHODS: UK Transplant Registry data on patient registrations and transplants were analysed to build survival on the list (M1) and survival post-transplantation (M2) statistical models...

INTRODUCTION: Continuous monitoring of the pressure reactivity index (PRx) provides an estimation of dynamic cerebral autoregulation (CA) at the bedside in traumatic brain injury (TBI) patients. Visualising the time-trend of PRx with a risk bar chart in ICM + software at the bedside allows for better real-time interpretability of the autoregulation status. When PRx>0.3 is sustained for long periods, typically of at least half an hour, the bar shows a pattern called "red solid line" (RSL)...

BACKGROUND: Technological advances in the field of virtual reality (VR) offer new opportunities in many areas of life, including medical education. The University of Münster has been using VR scenarios in the education of medical students for several years, especially for situations that are difficult to reproduce in reality (e.g., brain death). Due to the consistently positive feedback from students, a dermatological VR scenario for skin cancer screening was developed. OBJECTIVES: Presentation and first evaluation of the skin cancer screening VR scenario to determine to what extent the technical implementation of the scenario was evaluated overall by the students and how their subjective competence to perform a skin cancer screening changed over the course of the teaching unit (theory seminar, VR scenario, theoretical debriefing)...

Cervical spine manipulation is a known risk factor for vertebral artery dissection. In this report, we present a case of fatal vertebral artery dissection that occurred as the result of self-manipulation of the cervical spine. The decedent was a 40-year-old man with no significant past medical history. He was observed to "crack his neck" while at work. Soon after, he began experiencing neck pain, then developed strokelike symptoms and became unresponsive. He was transported to a local medical center, where imaging showed bilateral vertebral artery dissection...

BACKGROUND: Vertebral artery injury is a rare condition in trauma settings. In the advanced stages, it causes death. CASE: A 31-year-old Sundanese woman with cerebral edema, C2-C3 anterolisthesis, and Le Fort III fracture after a motorcycle accident was admitted to the emergency room. On the fifth day, she underwent arch bar maxillomandibular application and debridement in general anesthesia with a hyperextended neck position. Unfortunately, her rigid neck collar was removed in the high care unit before surgery...
