Organ procurement

Mareike Cora Janiak
All living organisms need to consume nutrients to grow, survive, and reproduce, making the successful acquisition of food resources a powerful selective pressure. However, acquiring food is only part of the challenge. While all animals spend much of their daily activity budget hunting, searching for, or otherwise procuring food, a large part of what is involved in overall nutrition occurs once the meal has been swallowed. Most nutritional components are too complex for immediate use and must be broken down into simpler compounds, which can then be absorbed by the body...

Available literature points to healthcare providers' discomfort with donation after cardiac death (DCD) and their perception of the public's reluctance toward the procedure. Using a national sample, we report on the communication content of actual DCD and donation after brain death (DBD) approaches by organ procurement organization (OPO) requesters and compare family decision makers' (FDMs') experiences of both modalities. We recruited 1,601 FDMs using a validated protocol; 347 (21.7%) were of potential DCD donors...

Advanced therapy medicinal products (ATMPs) represent the current pinnacle of 'patient-specific medicines' and will change the nature of medicine in the near future. They fall into three categories; somatic cell-therapy products, gene therapy products and cells or tissues for regenerative medicine, which are termed 'tissue engineered' products. The term also incorporates 'combination products' where a human cell or tissue is combined with a medical device. Plainly, many of these new medicines share similarities with conventional haematological stem cell transplant products and donor lymphocyte infusions as well as solid organ grafts and yet ATMPs are regulated as medicines and their development has remained predominantly in academic settings and within specialist centres...

Since implementation, the new UNOS OPTN kidney allocation system (KAS) has drastically expanded the pool of available kidneys to candidates that may have previously waited extended periods for an organ offer. This is particularly true for highly sensitized patients. The changes to the KAS have had ramifications throughout the transplant process, including for organ procurement organizations (OPO) and local transplant hospital call centers. Here, we will examine the impact of the new KAS on the organ donation process and highlight the necessary interactions between the OPO and transplant centers to best match donor kidneys and highly sensitized recipients...

Ischemia-reperfusion injury (IRI) is unavoidably caused by loss and subsequent restoration of blood flow during organ procurement and prolonged IRI results in increased rates of delayed graft function and early graft loss. The endogenously produced gasotransmitter, hydrogen sulfide (H2 S), is a novel molecule that mitigates hypoxic tissue injury. The current study investigates the protective mitochondrial effects of H2 S during in vivo cold storage and subsequent renal transplantation (RTx) and in vitro cold hypoxic renal injury...

Transplantation is one of the most highly regulated fields in health care. An important component of transplant oversight is the performance assessment of transplant centers as measured by 1-year patient and graft survival outcomes. The use of the Organ Procurement and Transplantation Network and Scientific Registry of Transplant Recipients flagging mechanism for quality improvement as criteria for Center for Medicare and Medicaid Services certification has resulted in greater importance in transplant program operations...

OBJECTIVES: Donors with bacteremia and sepsis are often considered to be controversial for organ retrieval due to potential transmission of an infectious agent to the recipient. Herein we report our initial experience of organ donation and transplantation results from donors with systemic infection. MATERIALS AND METHODS: From January 2013 to December 2014, 125 cases of donation were completed in our organ procurement organization including 90 cases of donation after brain death (DBD) and 35 cases of donation after circulatory death (DCD)...

BACKGROUND: The organ donation rate in Japan is much lower than that in other developed countries for several reasons. An advanced educational program for in-hospital procurement coordinators is a possible solution for this. We introduced a Transplant Procurement Management (TPM) educational program at Hyogo Prefecture, Japan. METHODS: Ten healthcare professionals at Hyogo Prefecture participated in the Advanced International TPM course to educate themselves on TPM and held 2 TPM Model Organ Procurement Training Workshops at Hyogo Prefecture for in-hospital procurement coordinators...

BACKGROUND: Because tissue transplantation (TTx) has not been familiar to the general public or even to medical staffs in Japan, awareness of TTx is very important to increase tissue donation. Our primary aim was to describe the current status of awareness of TTx in medical staffs and in the general public around Osaka. METHODS: Between July 2014 and February 2015, 1015 general public citizens, 203 medical staff members working in emergency hospitals, and 168 cardiothoracic surgeons were invited to complete a letter or web-based survey through the use of a self-designed questionnaire...

BACKGROUND: Organ donation after brain death is a major source for obtaining transplantable organs for patients with end-stage organ disease. However, the time from declaring brain death to organ procurement is often longer than expected. Analyzing factors that delay organ procurement may help to prevent damage to organs from marginal and unstable donors and aid in preparation for recipient operation. The aim of this study was to examine factors associated with the interval between the time of declaring brain death and organ procurement...

Establishing an organization to promote organ donation and a good organ procurement team assure quality and improve performance on organ donation rates. Brazil's organ procurement structure is based on 2 models disseminated worldwide: the "Spanish model," based on in-house coordinators, and the "American organ procurement organization (OPO) model," with extra-hospital coordinators. In 2006, Brazil's Federal Government had formally introduced the in-house coordination model for every hospital equipped with a mechanical ventilator bed...

OBJECTIVE: Critical organ shortages have resulted in ex vivo lung perfusion gaining clinical acceptance for lung evaluation and rehabilitation to expand the use of donation after circulatory death organs for lung transplantation. We hypothesized that an innovative use of airway pressure release ventilation during ex vivo lung perfusion improves lung function after transplantation. METHODS: Two groups (n = 4 animals/group) of porcine donation after circulatory death donor lungs were procured after hypoxic cardiac arrest and a 2-hour period of warm ischemia, followed by a 4-hour period of ex vivo lung perfusion rehabilitation with standard conventional volume-based ventilation or pressure-based airway pressure release ventilation...

The supply of liver grafts for treatment of end-stage liver disease continues to fall short of ongoing demands. Currently, most liver transplants originate from donations after brain death. Enhanced utilization of the present resources is prudent to address the needs of the population. Donation after circulatory or cardiac death is a mechanism whereby the availability of organs can be expanded. Donations after circulatory death pose unique challenges given their exposure to warm ischemia. Technical principles of donations after circulatory death procurement and pertinent studies investigating patient outcomes, graft outcomes, and complications are highlighted in this review...

Lung transplantation remains the definite treatment for various end-stage lung diseases. Cold flush perfusion, the standard method for organ procurement has severe limitations. Organ Care System (OCS; TransMedics, Inc., Andover, USA) is an approved method to preserve hearts for transplantation that allows for greatly reduced cold ischemic time. Consequently, the use of an adapted OCS lung as a portable full ex-vivo lung perfusion system in lung transplantation is currently under close evaluation. Areas covered: The aim of this article is to review the advantages and the role of the OCS in the field of lung transplantation by reviewing the latest literature and evaluating this novel procurement technique in the context of conventional methods like cold flush and regular ex-vivo lung perfusion...

BACKGROUND: Acute hypothyroidism after brain death results in hemodynamic impairments that limit availability of donor hearts. Thyroid hormone infusions can halt that process and lead to increased utilization of donor organs, but prolonged used of thyroid replacement has not been well studied. METHODS: We developed a 15 question survey regarding policies, procedures, and reporting of thyroid hormone use by OPOs. The survey was posted for five weeks on the Association of OPOs Portal...

Minimally invasive surgical approaches in transplantation are gaining increasing interest, and many centers are reporting their, mainly laparoscopic, experiences. Robotic surgery (RS) has some hypothetical advantages over traditional laparoscopy, and has been successfully applied, although infrequently to organ transplantation. Our goal was to review and critique the publications reporting RS use in organ transplantation. Most of the RS experience has been with living renal donor organ procurement and, to a lesser extent, with RS procedures in the transplant recipient...

AIM: To evaluate risk of recidivism on a case-by-case basis. METHODS: From our center's liver transplant program, we selected patients with alcoholic liver disease who were listed for transplant based on Ohio Solid Organ Transplantation Consortium (OSOTC) exception criteria. They were considered to have either a low or medium risk of recidivism, and had at least one or three or more months of abstinence, respectively. They were matched based on gender, age, and Model for End-Stage Liver Disease (MELD) score to controls with alcohol-induced cirrhosis from Organ Procurement and Transplant Network data...
