Abstract
This study investigated the influences of mother-daughter communication and social media on mothers' HPV vaccine refusal for their daughters aged 9-17. A cross-sectional online survey among 11,728 mothers of girls aged 9-17 in Shenzhen, China was implemented between July and October 2023. Multi-level logistic regression models were fitted. Among 11,728 participants, 43.2% refused to have their daughters receive an HPV vaccination. In multivariate analysis, more openness in the mother-daughter communication (AOR: 0.99, 95%CI: 0.98, 0.99), perceived more positive outcomes of mother-daughter communication (AOR: 0.77, 95%CI: 0.75, 0.79), higher frequency of exposure to testimonials about daughters' HPV vaccination (AOR: 0.81, 95%CI: 0.78, 0.85) and information encouraging parents to vaccinate their daughters against HPV on social media (AOR: 0.76, 95%CI: 0.73, 0.79), and thoughtful consideration of the veracity of the information specific to HPV vaccines (AOR: 0.80, 95%CI: 0.77, 0.83) were associated with lower vaccine refusal. Mothers who were not the main decision-makers of daughters' HPV vaccination (AOR: 1.28 to 1.46), negative outcome expectancies of mother-daughter communication (AOR: 1.06, 95%CI: 1.04, 1.08), and mothers' HPV vaccine refusal (AOR: 2.81, 95%CI: 2.58, 3.06) were associated with higher vaccine refusal for their daughters. The level of mothers' HPV vaccine refusal for their daughters was high in China. Openness and outcome expectancies of mother-daughter communication and information exposure on social media were considered key determinants of HPV vaccine refusal for daughters. Future HPV vaccination programs should consider these interpersonal factors.

Multifaceted Determinants of Sexual Intercourse with Non-Regular Female Sex Partners and Female Sex Workers among Male Factory Workers in China-A Cross-Sectional Survey. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:16008. [PMID: 36498089 PMCID: PMC9736560 DOI: 10.3390/ijerph192316008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/20/2022] [Revised: 11/24/2022] [Accepted: 11/28/2022] [Indexed: 06/17/2023]
Abstract
With a stratified multi-stage sampling approach, 1361 male factory workers in the Longhua district of the Shenzhen Municipality of China were selected to investigate the multifaceted determinants of sexual intercourse with non-regular female sex partners (NRP) and female sex workers (FSW) among them. The results showed that 24.5% and 21.2% of participants had sexual intercourse with NRP and FSW in the past 6 months, respectively. More specifically, at the individual level, perceived higher job stress and maladaptive coping styles were linked with a higher likelihood of having sexual intercourse with NRP and FSW (adjusted odds ratios [AOR] ranged from 1.06 to 1.17). At the interpersonal level, those who had higher exposure to information related to sexual intercourse with NRP or FSW were more likely to have sex with these female sex partners (AOR: 1.08 & 1.11). At the social structural level, perceived social norms supporting multiple sex partnerships were linked with a higher likelihood of having sexual intercourse with NRP and FSW (AOR: 1.10 & 1.11). No interaction effects were found between the variables at different levels. Providing pre-employment training to clarify roles and job duties, introducing adaptive coping strategies, and addressing misconceptions of social norms are useful strategies to reduce sexual intercourse with NRP or FSW.

Effects of polyethylene glycol-20k IV solution on donor management in a canine model of donor brain death. Biomed Pharmacother 2022; 152:113293. [PMID: 35714513 DOI: 10.1016/j.biopha.2022.113293] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2022] [Revised: 06/07/2022] [Accepted: 06/09/2022] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Traditionally, vasopressors and crystalloids have been used to stabilize brain dead donors; however, the use of crystalloid is fraught with complications. This study aimed to investigate the effectiveness of a newly developed impermeant solution, polyethylene glycol-20k IV solution (PEG-20k) for resuscitation and support of brain dead organ donors. METHODS Brain death was induced in adult beagle dogs and a set volume of PEG-20k or crystalloid solution was given thereafter. The animals were then resuscitated over 16 h with vasopressors and crystalloid as necessary to maintain mean arterial pressure of 80-100 mmHg. The kidneys were procured and cold-stored for 24 h, after which they were analyzed using the isolated perfused kidney model. RESULTS The study group required significantly less crystalloid volume and vasopressors while having less urine output and requiring less potassium supplementation than the control group. Though the two groups' mean arterial pressure and lactate levels were comparable, the study group's kidneys showed less preservation injury after short-term reperfusion indexed by decreased lactate dehydrogenase release and higher creatinine clearance than the control group. CONCLUSIONS The use of polyethylene glycol-20k IV solution for resuscitating brain dead donors decreases cell swelling and improves intravascular volume, thereby improving end organ oxygen delivery before procurement and so preventing ischemia-reperfusion injury after transplantation.

Abstract
INTRODUCTION The exposure of anesthesiologists to organ recovery procedures and the anesthetic technique used during organ recovery has not been systematically studied in the United States. METHODS A retrospective cohort study was conducted on all adult and pediatric patients who were declared brain dead between January 1, 2008, and June 30, 2019, and who progressed to organ donation at Harborview Medical Center. We describe the frequency of directing anesthetic care by attending anesthesiologists, anesthetic technique, and donor management targets during organ recovery. RESULTS In a cohort of 327 patients (286 adults and 41 children), the most common cause of brain death was traumatic brain injury (51.1%). Kidneys (94.4%) and liver (87.4%) were the most common organs recovered. On average, each year, an attending anesthesiologist cared for 1 (range: 1 to 7) brain-dead donor during organ retrieval. The average anesthetic time was 127±53.5 (mean±SD) minutes. Overall, 90% of patients received a neuromuscular blocker, 63.3% an inhaled anesthetic, and 33.9% an opioid. Donor management targets were achieved as follows: mean arterial pressure ≥70 mm Hg (93%), normothermia (96%), normoglycemia (84%), urine output >1 to 3 mL/kg/h (61%), and lung-protective ventilation (58%). CONCLUSIONS During organ recovery from brain-dead organ donors, anesthesiologists commonly administer neuromuscular blockers, inhaled anesthetics, and opioids, and strive to achieve donor management targets. While infrequently being exposed to these cases, it is expected that all anesthesiologists be cognizant of the physiological perturbations in brain-dead donors and achieve physiological targets to preserve end-organ function. These findings warrant further examination in a larger multi-institutional cohort.

Abstract
Organ transplantation is a life-saving intervention for patients suffering from end-stage organ failure, but it relies on the availability of donor organs. However, even when donors are available, the brain-dead organ donor is a clinically complex patient who presents many management challenges. Donor management with a goal of optimization of organ function is essential to maximizing the number of patients who can be helped by each individual donor. Thoughtful critical care management of the potential organ donor, with a focus on meeting donor management goals, can lead to improved donation outcomes.

Abstract
BACKGROUND Intraoperative fluid management may affect the outcome after kidney transplantation. However, the amount and type of fluid administered, and monitoring techniques vary greatly between institutions and there are limited prospective randomized trials and meta-analyses to guide fluid management in kidney transplant recipients. METHODS Members of the American Society of Anesthesiologists (ASA) committee on transplantation reviewed the current literature on the amount and type of fluids (albumin, starches, 0.9% saline, and balanced crystalloid solutions) administered and the different monitors used to assess fluid status, resulting in this consensus statement with recommendations based on the best available evidence. RESULTS Review of the current literature suggests that starch solutions are associated with increased risk of renal injury in randomized trials and should be avoided in kidney donors and recipients. There is no evidence supporting the routine use of albumin solutions in kidney transplants. Balanced crystalloid solutions such as Lactated Ringer are associated with less acidosis and may lead to less hyperkalemia than 0.9% saline solutions. Central venous pressure is only weakly supported as a tool to assess fluid status. CONCLUSIONS These recommendations may be useful to anesthesiologists making fluid management decisions during kidney transplantation and facilitate future research on this topic.

Recipient pre-existing chronic hypotension is associated with delayed graft function and inferior graft survival in kidney transplantation from elderly donors. PLoS One 2021; 16:e0249552.

Abstract
Background Pre-existing chronic hypotension affects a percentage of kidney transplanted patients (KTs). Although a relationship with delayed graft function (DGF) has been hypothesized, available data are still scarce and inconclusive. Methods A monocentric retrospective observational study was performed on 1127 consecutive KTs from brain death donors over 11 years (2003–2013), classified according to their pre-transplant Mean Blood Pressure (MBP) as hypotensive (MBP < 80 mmHg) or normal-hypertensive (MBP ≥ 80 mmHg, with or without effective antihypertensive therapy). Results Univariate analysis showed that a pre-existing hypotension is associated to DGF occurrence (p<0.01; OR for KTs with MBP < 80 mmHg, 4.5; 95% confidence interval [CI], 2.7 to 7.5). Chronic hypotension remained a major predictive factor for DGF development in the logistic regression model adjusted for all DGF determinants. Adjunctive evaluations on paired grafts performed in two different recipients (one hypotensive and the other one normal-hypertensive) confirmed this assumption. Although graft survival was only associated with DGF but not with chronic hypotension in the overall population, stratification according to donor age revealed that death-censored graft survival was significantly lower in hypotensive patients who received a KT from >50 years old donor. Conclusions Our findings suggest that pre-existing recipient hypotension, and the subsequent hypotension-related DGF, could be considered a significant detrimental factor, especially when elderly donors are involved in the transplant procedure.

Abstract
PURPOSE We aimed to investigate whether 6% HES 130/0.4 was associated with postoperative reduction of estimated glomerular filtration rate (eGFR) in donor patients who underwent nephrectomy for living kidney transplantation. METHODS This retrospective study included 213 living kidney transplant donors treated at Kyushu University Hospital in Japan from April 2014 to March 2018. Patients who were administered 6% HES 130/0.4 were allocated in the HES group (n = 108), and those who were not were allocated in the control group (n = 105). The postoperative decrements in estimated glomerular filtration rates (eGFRs) from preoperative values were calculated on postoperative days (PODs) 1, 3, and 14. Decline in kidney function (DKF) according to the Kidney Disease: Improving Global Outcomes (KDIGO) classification were analyzed by multivariable-adjusted ordinal logistic regression to estimate odds ratios (ORs) for postoperative DKF. RESULTS In HES group, administration amount of HES was median 9.4 [interquartile range: 8.2-14.3] ml/kg. Postoperative decrements in eGFR were similar in the control and HES groups on POD 1 (control group: mean 32.0 vs. HES group: 33.0 mL/min/1.73 m2), same as POD 3 (21.1 vs. 22.4 mL/min/1.73 m2) and POD 14 (26.0 vs. 25.9 mL/min/1.73 m2), even after adjusting for confounding factors. The multivariable-adjusted ORs for postoperative DKF did not significantly increase in the HES group on POD 1 (OR: 0.88), POD 3 (OR: 0.96), and POD 14 (OR: 0.52) compared with the control group. CONCLUSION Six percent HES 130/0.4 is not associated with postoperative renal dysfunction in donor patients undergoing nephrectomy for kidney transplantation.

Deceased organ donor factors influencing pancreatic graft transplantation and survival. Clin Transplant 2020; 33:e13571.

Abstract
Criteria for organ acceptance in brain-dead organ donors remain inconsistent, especially when concerning pancreatic transplants. We sought to examine donor-specific predictors of pancreatic graft use and survival to better guide the selection and management of potential donors. A prospective observational study of all donors from ten organ procurement organizations was conducted from March 2012 to January 2015. Critical care endpoints were collected at 4 standardized time points. Data associated with pancreatic transplantation and graft survival rates were first determined using univariate analyses, and then logistic regression was used to identify independent predictors of these two outcomes. From 1819 donors, 238 (13.1%) pancreata were transplanted, and at a mean follow-up of 192 days, 218 (91.6%) grafts had survived. After regression analysis, donor age (OR = 0.89), HgbA1C (OR = 0.07), and achieving the donor management goal (DMG) for ejection fraction at allocation of ≥50% (OR = 3.29) remained as independent predictors of pancreatic utilization. On regression analysis, graft survival was independently predicted by lower donor age (OR = 0.93) and achieving the DMGs for mean arterial pressure (60-110 mm Hg) and glucose (≤180 mg/dL) at separate time points. These results may help guide the management and selection of potential pancreatic donors after brain death.

Abstract
BACKGROUND In a recent trial, targeted mild hypothermia in brain-dead organ donors significantly reduced the incidence of delayed graft function after kidney transplantation. This trial was stopped early for efficacy. Here, we report long-term graft survival for all organs along with donor critical care end points. METHODS We assessed graft survival through 1 year of all solid organs transplanted from 370 donors who had been randomly assigned to hypothermia (34-35°C) or normothermia (36.5-37.5°C) before donation. Additionally, changes in standardized critical care end points were compared between donors in each group. RESULTS Mild hypothermia was associated with a nonsignificant improvement in 1-year kidney transplant survival (95% versus 92%; hazard ratio, 0.61 [0.31-1.20]; P = 0.15). Mild hypothermia was associated with higher 1-year graft survival in the subgroup of standard criteria donors (97% versus 93%; hazard ratio, 0.39 [0.15 to -1.00]; P = 0.05). There were no significant differences in graft survival of extrarenal organs. There were no differences in critical care end points between groups. CONCLUSIONS Mild hypothermia in the donor safely reduced the rate of delayed graft function in kidney transplant recipients without adversely affecting donor physiology or extrarenal graft survival. Kidneys from standard criteria donors who received targeted mild hypothermia had improved 1-year graft survival.

Abstract
Mortality remains high for patients on the waiting list for organ transplantation. A marked imbalance between the number of available organs and recipients that need to be transplanted persists. Organs from deceased donors are often declined due to perceived and actual suboptimal quality. Adequate donor management offers an opportunity to reduce organ injury and maximise the number of organs than can be offered in order to respect the donor's altruistic gift. The cornerstones of management include: correction of hypovolaemia; maintenance of organ perfusion; prompt treatment of diabetes insipidus; corticosteroid therapy; and lung protective ventilation. The interventions used to deliver these goals are largely based on pathophysiological rationale or extrapolations from general critical care patients. There is currently insufficient high-quality evidence that has assessed whether any interventions in the donor after brain death may actually improve immediate post-transplant function and long-term graft survival or recipient survival after transplantation. Improvements in our understanding of the underlying mechanisms following brain death, in particular the role of immunological and metabolic changes in donors, offer promising future therapeutic opportunities to increase organ utilisation. Establishing a UK donor management research programme involves consideration of ethical, logistical and legal issues that will benefit transplanted patients while respecting the wishes of donors and their families.

Abstract
PURPOSE OF REVIEW Kidney transplantation is the best treatment for end-stage renal disease. However, due to organ shortage, suboptimal grafts are increasingly being used. RECENT FINDINGS We carried out a review on the methods and techniques of organ optimization in the cadaveric setting. Donor care is the first link in a chain of care. Right after brain death, there is a set of changes, of which hormonal and hemodynamic changes are the most relevant. Several studies have been conducted to determine which drugs to administer, although in most cases, the results are not definitive. The main goal seems rather achieve a set of biochemical and hemodynamic objectives. The ischemia-reperfusion injury is a critical factor for kidney damage in transplantation. One of the ways found to deal with this type of injury is preconditioning. Local and remote ischemic preconditioning has been studied for various organs, but studies on the kidney are scarce. A new promising area is pharmacological preconditioning, which is taking its first steps. Main surgical techniques were established in the late twentieth century. Some minor new features have been introduced to deal with anatomical variations or the emergence of donation after circulatory death. Finally, after harvesting, it is necessary to ensure the best conditions for the kidneys until the time of transplantation. Much has evolved since static cold preservation, but the best preservation conditions are yet to be determined. Conservation in the cold has come to be questioned, and great results have appeared at temperatures closer to physiological.

Abstract
PURPOSE Delayed graft function is a major complication after kidney transplantation affecting patients' long-term outcome. The aim of this study was to identify modifiable risk factors for delayed graft function after deceased donor kidney transplantation. METHODS This is a single-center retrospective cohort study of a university transplantation center. Univariate and multivariate step-wise logistic regression analysis of patient-specific and procedural risk factors were conducted. RESULTS We analyzed 380 deceased donor kidney transplantation patients between October 30, 2008 and December 30, 2017. The incidence of delayed graft function was 15% (58/380). Among the patient-specific risk factors recipient diabetes (2.8 [1.4-5.9] odds ratio [OR] [95% confidence interval [CI]]), American Society of Anesthesiologist score of 4 (2.7 [1.2-6.5] OR [95% CI]), cold ischemic time >13 hours (2.8 [1.5-5.3] OR [95% CI]) and donor age >55 years (1.9 [1.01-3.6] OR [95% CI]) revealed significance. The significant intraoperative, procedural risk factors included the use of colloids (3.9 [1.4-11.3] OR [95% CI]), albumin (3.0 [1.2-7.5] OR [95% CI]), crystalloids >3000 mL (3.1 [1.2-7.5] OR [95% CI]) and mean arterial pressure <80 mm Hg at the time of reperfusion (2.4 [1.2-4.8] OR [95% CI]). CONCLUSION Patients undergoing deceased donor kidney transplantation with a mean arterial pressure >80 mm Hg at the time of transplant reperfusion without requiring excessive fluid therapy in terms of colloids, albumin or crystalloids >3000 mL are less likely to develop delayed graft function.

Abstract
Purpose Prognosis of solid organ transplant (SOT) recipients has improved, mainly because of better prevention of rejection by immunosuppressive therapies. However, SOT recipients are highly susceptible to conventional and opportunistic infections, which represent a major cause of morbidity, graft dysfunction and mortality. Methods Narrative review. Results We cover the current epidemiology and main aspects of infections in SOT recipients including risk factors such as postoperative risks and specific risks for different transplant recipients, key points on anti-infective prophylaxis as well as diagnostic and therapeutic approaches. We provide an up-to-date guide for management of the main syndromes that can be encountered in SOT recipients including acute respiratory failure, sepsis or septic shock, and central nervous system infections as well as bacterial infections with multidrug-resistant strains, invasive fungal diseases, viral infections and less common pathogens that may impact this patient population. Conclusion We provide state-of the art review of available knowledge of critically ill SOT patients with infections.

Abstract
Therapeutic hypothermia (TH) is clinically used to improve neurologic outcomes in patients with anoxic brain injury after cardiopulmonary resuscitation (CPR). For patients that regress and become organ donors after neurologic determination of death (DNDDs), the impact of TH received before determination of death on organ donation outcomes remains unknown. A prospective observational study of all adult DNDDs that received CPR and had anoxia as a cause of death from March 2013 to December 2014 was conducted across 20 organ procurement organizations (OPOs) in the United States. Main outcome measures included organs transplanted per donor (OTPD), specific organ transplantation rates, and recipient graft outcomes. One thousand ninety eight DNDDs met inclusion criteria, with 46% having received TH before determination of death. DNDDs with hypothermia before death had a similar number of OTPD (2.74 vs. 2.69, p = 0.61) and similar transplantation rates of individual organs. With regards to recipients, there was significantly less delayed graft function (DGF) in kidney grafts from donors who received TH before death (24% vs. 30%, p = 0.02). After adjusting for donor, recipient, and graft related factors, the protective effect of TH on DGF persisted (OR 0.75, 95%CI [0.56-0.995], p = 0.046). TH before death in the donor is independently associated with a 25% decrease in DGF among kidney recipients. This should be considered a protective donor selection factor in guiding the decision to accept or reject an organ for transplantation.

METHODS Seven areas of donor management were considered for this review: hemodynamic management; fluids and electrolytes; respiratory management; endocrine management; temperature management; anaemia and coagulation; infection management. For each subchapter, a narrative review was conducted. RESULTS AND CONCLUSIONS Most elements in the current recommendations and guidelines are based on pathophysiological reasoning, epidemiological observations, or extrapolations from general ICU management strategies, and not on evidence from randomized controlled trials. The cardiorespiratory management of brain-dead donors is very similar to the management of critically ill patients, and the same applies to the management of anaemia and coagulation. Central diabetes insipidus is of particular concern, and should be diagnosed based on clinical criteria. Depending on the degree of vasopressor dependency, it can be treated with intermittent desmopressin or continuous vasopressin, intravenously. Temperature management of the donor is an area of uncertainty, but it appears reasonable to strive for a core temperature of > 35 °C. The indications and controversies regarding endocrine therapies, in particular thyroid hormone replacement therapy, and corticosteroid therapy, are discussed. The potential donor should be assessed clinically for infections, and screening tests for specific infections are an essential part of donor management. Although the rate of infection transmission from donor to receptor is low, certain infections are still a formal contraindication to organ donation. However, new antiviral drugs and strategies now allow organ donation from certain infected donors to be done safely.

Organ-Protective Intensive Care in Organ Donors. DEUTSCHES ARZTEBLATT INTERNATIONAL 2018; 113:552-8. [PMID: 27598872 DOI: 10.3238/arztebl.2016.0552] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/03/2015] [Revised: 05/02/2016] [Accepted: 05/02/2016] [Indexed: 12/22/2022]
Abstract
BACKGROUND The ascertainment of brain death (the irreversible, total loss of brain function) gives the physician the opportunity to limit or stop further treatment. Alternatively, if the brain-dead individual is an organ donor, the mode of treatment can be changed from patient-centered to donationcentered. Consensus-derived recommendations for the organ-protective treatment of brain-dead organ donors are not yet available in Germany. METHODS This review is based on pertinent publications retrieved by a selective search in PubMed, and on the authors' clinical experience. RESULTS Brain death causes major pathophysiological changes, including an increase in catecholamine levels and a sudden drop in the concentration of multiple hormones, among them antidiuretic hormone, cortisol, insulin, and triand tetraiodothyronine. These changes affect the function of all organ systems, as well as the hemodynamic state and the regulation of body temperature. The use of standardized donor management protocols might well increase the rate of transplanted organs per donor and improve the quality of the transplanted organs. In addition, the administration of methylprednisolone, desmopressin, and vasopressin could be a useful supplement to treatment in some cases. Randomized controlled trials have not yet demonstrated either improved organ function or prolonged survival of the transplant recipients. CONCLUSION The evidence base for organ-protective intensive care is weak; most of the available evidence is on the level of expert opinion. There is good reason to believe, however, that the continuation of intensive care, in the sense of early donor management, can make organ transplantation more successful both by increasing the number of transplantable organs and by improving organ quality.

Abstract
Worldwide 715 482 patients have received a lifesaving organ transplant since 1988. During this time, there have been advances in donor management and in the perioperative care of the organ transplant recipient, resulting in marked improvements in long-term survival. Although the number of organs recovered has increased year after year, a greater demand has produced a critical organ shortage. The majority of organs are from deceased donors; however, some are not suitable for transplantation. Some of this loss is due to management of the donor. Improved donor care may increase the number of available organs and help close the existing gap in supply and demand. In order to address this concern, The Organ Donation and Transplantation Alliance, the Association of Organ Procurement Organizations, and the Transplant and Critical Care Committees of the American Society of Anesthesiologists have formulated evidence-based guidelines, which include a call for greater involvement and oversight by anesthesiologists and critical care specialists, as well as uniform reporting of data during organ procurement and recovery.

Abstract
Organ transplantation improves survival and quality of life in patients with end-organ failure. Waiting lists continue to grow across the world despite remarkable advances in the transplantation process, from the creation of public engagement campaigns to the development of critical pathways for the timely identification, referral, approach, and treatment of the potential organ donor. The pathophysiology of dying triggers systemic changes that are intimately related to organ viability. The intensive care management of the potential organ donor optimizes organ function and improves the donation yield, representing a significant step in reducing the mismatch between organ supply and demand. Different beliefs and cultures reflect diverse legislations and donation practices amongst different countries, creating a challenge to standardized practices. Maintaining public trust is necessary for continued progress in organ donation and transplantation, hence the urge for a joint effort in creating uniform protocols that ensure transparent practices within the medical community.

Abstract
OBJECTIVES To review epidemiologic data's and medical results of deceased donation in renal transplantation. MATERIAL AND METHODS Relevant publications were identified through Medline (http://www.ncbi.nlm.nih.gov) and Embase (http://www.embase.com) database using the following keywords, alone or in association, "brain death; cardiac arrest; deceased donation; organ procurement; transplantation". Articles were selected according to methods, language of publication and relevance. The reference lists were used to identify additional historical studies of interest. Both prospective and retrospective series, in French and English, as well as review articles and recommendations were selected. In addition, French national transplant and health agencies (http://www.agence-biomedecine.fr and http://www.has-sante.fr) databases were screened using identical keywords. A total of 2498 articles, 8 official reports and 17 newspaper articles were identified; after careful selection 157 publications were eligible for our review. RESULTS Deceased donation may involve either brain death or non-heartbeating donors (NHBD). Organ shortage led to the procurement of organs from expanded-criteria donors, with an increased age at donation and extended vascular disease, leading to inferior results after transplantation and underlining the need for careful donor management during brain death or cardiac arrest. Evolution of French legislation covering bioethics allowed procurement from Maastricht categories II and recently III non-heartbeating donors. CONCLUSION The increase of organ shortage emphasizes the need for a rigorous surgical technique during procurement to avoid loss of transplants. A history or current neoplasm in deceased-donors, requires attention to increase the pool of organs without putting the recipients at risk for cancer transmission. French NHBD program, especially from Maastricht category III, may stand for a potential source of valuable organs.

Abstract
Introduction: Despite continuous advances in transplant medicine, there is a persistent worldwide shortage of organs available for donation. There is a growing body of research that supports that optimal management of deceased organ donors in Intensive Care Unit can substantially increase the availability of organs for transplant and improve outcomes in transplant recipients. Methods: A systematic literature review was performed, comprising a comprehensive search of the PubMed database for relevant terms, as well as individual assessment of references included in large original investigations, and comprehensive society guidelines. Results: In addition to overall adherence to catastrophic brain injury guidelines, optimization of physiologic state in accordance with established donor management goals (DMGs), and establishment of system-wide processes for ensuring early referral to organ procurement organizations (OPOs), several specific critical care management strategies have been associated with improved rates and outcomes of renal transplantation from deceased donors. These include vasoactive medication selection, maintenance of euvolemia, avoidance of hydroxyethyl starch, glycemic control, targeted temperature management, and blood transfusions if indicated. Conclusions: Management of deceased organ donors should focus first on maintaining adequate perfusion to all organ systems through adherence to standard critical care guidelines, early referral to OPOs, and family support. Furthermore, several specific DMGs and strategies have been recently shown to improve both the rates and outcomes of organ transplantation.
