Abstract
INTRODUCTION Grafts with multiple renal arteries (MRAs) were historically considered a relative contraindication to transplantation due to the higher risk of vascular and urologic complications. This study aimed to evaluate graft and patient survival between single renal artery (SRA) and MRA living-donor kidney transplants. METHODS An electronic literature search was conducted on PubMed, EMBASE, and Scopus for prospective or retrospective studies comparing SRA versus MRA in living donor renal transplantation, with the provision of Kaplan-Meier curves for recipient overall survival (OS) or graft survival (GS). A graphical reconstructive algorithm was used to obtain OS and GS of individual patients, which was then pooled under random-effects individual patient data (IPD) meta-analysis using Cox-models to determine hazard ratios (HRs) and 95% confidence intervals (CIs). Meta-regression of baseline covariates versus HRs of OS and GS was performed for variables reported in 10 or more studies. RESULTS Fourteen studies were retrieved, of which 13 (8400 patients) reported OS and 9 (6912 patients) reported GS. There were no significant differences in OS (shared-frailty HR = .94, 95%CI = .85-1.03, p = .172) or GS (shared-frailty HR = .95, 95%CI = .83-1.08, p = .419) between SRA and MRA. This comparison remained non-significant even when restricted to open- or laparoscopic-only studies. Meta-regression yielded no significant associations of GS with donor age, recipient age, and percentage of double renal arteries within the MRA arm. CONCLUSIONS The similar rates of GS and OS between MRA and SRA grafts suggest that there is no need for discrimination between the two when evaluating donors for nephrectomy.

Abstract
INTRODUCTION Racial/ethnic disparities in living donor kidney transplantation (LDKT) are a persistent challenge. Although nearly all directed donations are from members of patients' social networks, little is known about which social network members take steps toward living kidney donation, which do not, and what mechanisms contribute to racial/ethnic LDKT disparities. METHODS We describe the design and rationale of the Friends and Family of Kidney Transplant Patients Study, a factorial experimental fielding two interventions designed to promote LKD discussions. Participants are kidney transplant candidates at two centers who are interviewed and delivered an intervention by trained center research coordinators. The search intervention advises patients on which social network members are most likely to be LKD contraindication-free; the script intervention advises patients on how to initiate effective LKD discussions. Participants are randomized into four conditions: no intervention, search only, script only, or both search and script. Patients also complete a survey and optionally provide social network member contact information so they can be surveyed directly. This study will seek to enroll 200 transplant candidates. The primary outcome is LDKT receipt. Secondary outcomes include live donor screening and medical evaluations and outcomes. Tertiary outcomes include LDKT self-efficacy, concerns, knowledge, and willingness, measured before and after the interventions. CONCLUSION This study will assess the effectiveness of two interventions to promote LKD and ameliorate Black-White disparities. It will also collect unprecedented information on transplant candidates' social network members, enabling future work to address network member structural barriers to LKD.

Abstract
BACKGROUND Living donor kidney transplantation (LDKT) is the best treatment option for patients with kidney failure and offers significant medical and economic advantages for both patients and health systems. Despite this, rates of LDKT in Canada have stagnated and vary significantly across Canadian provinces, the reasons for which are not well understood. Our prior work has suggested that system-level factors may be contributing to these differences. Identifying these factors can help inform system-level interventions to increase LDKT. OBJECTIVE Our objective is to generate a systemic interpretation of LDKT delivery across provincial health systems with variable performance. We aim to identify the attributes and processes that facilitate the delivery of LDKT to patients, and those that create barriers and compare these across systems with variable performance. These objectives are contextualized within our broader goal of increasing rates of LDKT in Canada, particularly in lower-performing provinces. METHODS This research takes the form of a qualitative comparative case study analysis of 3 provincial health systems in Canada that have high, moderate, and low rates of LDKT performance (the percentage of LDKT to all kidney transplantations performed). Our approach is underpinned by an understanding of health systems as complex adaptive systems that are multilevel and interconnected, and involve nonlinear interactions between people and organizations, operating within a loosely bounded network. Data collection will comprise semistructured interviews, document reviews, and focus groups. Individual case studies will be conducted and analyzed using inductive thematic analysis. Following this, our comparative analysis will operationalize resource-based theory to compare case study data and generate explanations for our research question. RESULTS This project was funded from 2020 to 2023. Individual case studies were carried out between November 2020 and August 2022. The comparative case analysis will begin in December 2022 and is expected to conclude in April 2023. Submission of the publication is projected for June 2023. CONCLUSIONS By investigating health systems as complex adaptive systems and making comparisons across provinces, this study will identify how health systems can improve the delivery of LDKT to patients with kidney failure. Our resource-based theory framework will provide a granular analysis of the attributes and processes that facilitate or create barriers to LDKT delivery across multiple organizations and levels of practice. Our findings will have practice and policy implications and help inform transferrable competencies and system-level interventions conducive to increasing LDKT.

Abstract
Introduction: Lack of knowledge about living donor kidney transplant and difficulties in approaching potential donors constitute barriers for many patients and may contribute to inequality of access. Project Aims: Renal Education and Choices at Home was a UK single-centre pilot of home education; an initiative aiming to overcome barriers by increasing knowledge among patients and support networks and by facilitating living donation discussion in the patient's home. Design: This was a pre-post comparison of knowledge, attitude, and ability to communicate about transplant. Pre-visit knowledge about treatment options and attitudes towards transplant were measured using a validated questionnaire, repeated 4-6 weeks post-visit, to assess the session's impact, along with an evaluation survey, to determine how patients perceived the session. Results: From November 2018 to February 2020, a nurse specialist delivered living donor transplant education sessions in the homes of 86 patients, attended by 141 additional invitees. Home visits led to a significant improvement in knowledge about renal therapies, including living donor transplantation. The evaluation of the home visits by patients and invitees was overwhelmingly positive. Of the 86 patients visited, 46 (53%) had at least one potential donor initiating the assessment process following the visit. Overall, 78 potential donors initiated the assessment process. Conclusion: Home education contributed to addressing recognised barriers, in a way that was well received by patients and was novel in our health system. Home education may be particularly beneficial for patients affected by known barriers to living donor transplantation such as socio-economic deprivation.

Abstract
BACKGROUND Patient information about living donor kidney transplantation is used to supplement conversations between health professionals, people with advanced kidney disease and potential kidney donors. It is not known if the information is designed to support decision-making about renal replacement options and if it helps people discuss living kidney donation with family and friends. OBJECTIVE Critical review of resources used in outpatient kidney consultations to support patients' decision-making about living kidney donor transplantation. DESIGN Mixed methods including an audit questionnaire and critical analysis of patient information leaflets. PARTICIPANTS AND MEASUREMENTS All kidney transplant centres and renal units in United Kingdom received a questionnaire to elicit by whom, how, and when information about living kidney donation is delivered. Copies of leaflets were requested. A coding frame was utilised to produce a quality score for each leaflet. RESULTS Thirty-nine (54%) units participated. Patients discussed living donor kidney transplantation with nephrologists (100%), living donor nurse (94%), transplant co-ordinator (94%), and predialysis nurse (86%). Twenty-three leaflets were provided and reviewed, mean quality scores for inclusion of information known to support shared decision-making was m = 2.82 out of 10 (range = 0-6, SD = 1.53). Readability scores indicated they were 'fairly difficult to read' (M = 56.3, range = 0-100, SD = 9.4). Few included cultural and faith information. Two leaflets were designed to facilitate conversations with others about donation. CONCLUSIONS Leaflets are unlikely to adequately support decision-making between options and discussions about donation. Services writing and updating patient leaflets may benefit from our six principles to guide their development.

Abstract
This study analyzed survey results regarding awareness of living minors' organ donation. The questionnaires focused on changes in how respondents felt about donations by living minors after eliciting the uncertainty of long-term outcomes for living donors and recipients. The respondents were categorized as minors, adults affiliated with non-medical jobs (Non-Meds), and adults affiliated with medical jobs (Meds). The rates of awareness of living organ donation were significantly different; minors at 86.2%, non-Meds at 82.0%, and Meds at 98.7% (p < 0.001). Only 41.4% of Minors and 32.0% of Non-Meds were aware of organ donation by minors, while 70.3% of Meds were (p < 0.001). The response rate of opposition to organ donation by minors was highest for Meds and remained the same before and after (54.4%-57.7%, p = 0.311). However, the opposition rate in Non-Meds significantly increased (32.4%-46.7%) after learning about the uncertainty of long-term outcomes (p = 0.009). The study found that Non-Meds lacked adequate knowledge regarding organ donation by minors and their potential lethal outcomes. Their attitudes toward organ donation by minors could be changed by giving structured information. It is necessary to provide exact information and raise social awareness regarding organ donation by living minors.

Abstract
INTRODUCTION Living donor kidney transplantation (LDKT) is accepted as first-line treatment for patients with end-stage kidney disease with advantages over deceased donor kidney transplantation (DDKT). Still, how the known detrimental effect of HLA mismatch (MM) may hamper these advantages remains unsettled. We sought to determine the effect of the degree of HLA MM, separately in deceased and living donor renal allograft outcomes. METHODS We evaluated all adults submitted to LDKT and DDKT at our center between 2006 and 2018. Their HLA MM was classified according to the British Society of Transplantation system in low mismatch (LM) (level 1-2) and high mismatch (HM) (level 3-4). Acute rejection (AR) and global or censored graft survival were the outcomes of interest. Recipients were followed up from transplant until death, graft failure or the end of 2020. Results: One thousand sixty-eight kidney transplant recipients were analyzed, 815 (76%) received a DDKT whereas 253 (24%) received an LDKT. From those submitted to DDKT, 95 (12%) had an LM and 720 (88%) had an HM, whereas in LDKT 32 (13%) had an LM and 221 (87%) had an HM. The AR at one year was 9% in the full cohort. Significant risk factors for AR were HM DDKT (OR:2.3, P=0.047) or HM LDKT (OR:5.6, P=0.003) (LM DDKT as reference), calculated panel-reactive antibody (cPRA) ≥5% (OR:1.9, P=0.040) and delayed graft function (DGF), (OR:3.2, P<0.001). Censored graft survival (CGS) at five years was 96% in the full cohort. Independent predictors for censored graft failure (CGF) were HM LDKT (HR:0.2, P=0.046) (LM DDKT as reference), AR (HR:2.7, P=0.008) and DGF (HR:2.2, P=0.017). Global graft survival (GGS) at five years was 91% in the full cohort. Independent predictors for global graft failure (GGF) were HM LDKT (HR:0.2, P=0.042) (LM DDKT as reference), recipient age (HR:1.8, P<0.001) and DGF (HR:1.8, P=0.006). No AR, CGF or GGF episodes were observed in the LM LDKT group. CONCLUSIONS In our cohort, the level of HLA MM increased the risk of AR independently of donor type. Considering short graft survival, our results support the advantage of living donor vs deceased donor even with an increased HLA MM. However, its effect on long-term graft survival remains to be settled, emphasizing the need for further studies on this matter.

Abstract
Background Although many transplant programs have been forced to suspend living donor transplants due to the emergence of coronavirus disease (COVID‐19), there are relatively few real‐time databases to assess center‐level transplant activities. We aimed to delineate the actual impact of COVID‐19 on living donor transplant programs and the resumption process in Japan. Methods In a nationwide survey, questionnaires were sent to 32 liver transplant programs that had performed at least more than one case of living donor liver transplantation in 2019 and 132 kidney transplant programs that had performed more than one living donor kidney transplantation in 2018. Results Thirty‐one (96.9%) and 125 (94.7%) liver and kidney transplant programs responded, respectively. In the early pandemic period, 67.7% (21/31) of liver programs and 29.8% (37/125) of kidney programs were able to maintain transplant activities similar to those during the pre‐pandemic period. After temporal suspension, 58.1% of kidney programs resumed their transplant activity after the number of local COVID‐19 cases peaked. Establishing institutional COVID‐19 screening, triage, and therapeutic management protocols was mandatory to resume transplant activity for 64.5% and 67.7% of liver and kidney programs, respectively. In the future wave of COVID‐19, 67.7% of liver programs would be affected by institutional COVID‐19 intensive care unit‐bound patient numbers, and 55.7% of kidney programs would stop if hospital‐acquired severe acute respiratory syndrome coronavirus‐2 (SARS‐CoV‐2) infection spreads. Conclusions: This nationwide survey revealed for the first time how living donor liver and kidney transplant programs changed in response to the COVID‐19 pandemic in a country where living donor transplantations are predominant.

Abstract
Living donor kidney transplantation is a widely performed medical procedure. Living kidney donation requires an in-depth health assessment of candidates. The potential living kidney donor must remain healthy after kidney removal. A consequence of donation can be a decrease in glomerular filtration rate (GFR), and donors can become at risk of developing chronic kidney disease (CKD). We present a rationale for potential living kidney donor withdrawal due to Paget's disease of bone (PDB) based on a literature review. The treatment for PDB includes the use of, for example, non-steroidal anti-inflammatory drugs (NSAIDs), which can lead to acute kidney injury (AKI) as well as CKD, or bisphosphonates, which are not recommended for patients with decreased GFR.

Abstract
We evaluated the temporal trend of preemptive kidney transplantation (KT) and the effect of pretransplant dialysis duration on post-transplant outcomes. This was a nationwide cohort study of the first-time 3392 living donor KT (LDKT) recipients (2014-2019). The annual changes in proportion of preemptive KT, factors associated with preemptive KT, and post-transplant outcomes were analyzed. Preemptive KT was performed in 816 (24.1%) patients. Annual trend analysis revealed gradual decrease in preemptive KT over time (P = 0.042). Among the underlying causes of preemptive KT, the proportion of diabetes increased and that of glomerulonephritis decreased during the study period. Glomerulonephritis as the primary renal disease was a predictor of preemptive KT. Patients with pretransplant dialysis >6 months showed increased graft failure risk than preemptive KT in the subdistribution of hazard model for competing risk (adjusted hazard ratio [aHR], 2.53; 95% confidence interval [CI], 1.09-5.87; P = 0.031) and in propensity score-matched analysis (aHR, 2.45; 95% CI, 1.02-5.92; P = 0.034); however, pretransplant dialysis ≤6 months showed comparable graft survival with preemptive KT in both analyses. Preemptive KT declined over successive years, associated with an increase in diabetes and a decrease in glomerulonephritis as underlying causes of KT. Short period of dialysis less than 6 months does not affect graft survival compared with preemptive KT; however, longer dialysis decreases graft survival.

Abstract
BACKGROUND Kidney transplantation (KT), a treatment option for end-stage kidney disease (ESKD), is associated with longer survival and improved quality of life compared with dialysis. Inequities in access to KT, and specifically, living donor kidney transplantation (LDKT), have been documented in Canada along various demographic dimensions. In this article, we review existing evidence about inequitable access and barriers to KT and LDKT for patients from Indigenous communities in Canada. OBJECTIVE To characterize the current state of literature on access to KT and LDKT among Indigenous communities in Canada and to answer the research question, "what factors may influence inequitable access to KT among Indigenous communities in Canada." ELIGIBILITY CRITERIA Databases and gray literature were searched in June and November 2020 for full-text original research articles or gray literature resources addressing KT access or barriers in Indigenous communities in Canada. A total of 26 articles were analyzed thematically. SOURCES OF EVIDENCE Gray literature and CINAHL, OVID Medline, OVID Embase, and Cochrane databases. CHARTING METHODS Literature characteristics were recorded and findings which described rates of and factors that influence access to KT were summarized in a narrative account. Key themes were subsequently identified and synthesized thematically in the review. RESULTS Indigenous communities in Canada experience various barriers in accessing culturally safe medical information and care, resulting in inequitable access to KT. Barriers include insufficient incorporation of Indigenous ways of knowing and being in information dissemination and care for ESKD and KT, spiritual concerns, health beliefs, logistical hurdles to accessing care, and systemic mistrust resulting from colonialism and systemic racism. LIMITATIONS This review included studies that used various methodologies and did not assess study quality. Data on Indigenous status were not reported or defined in a standardized manner. Indigenous communities are not homogeneous and views on organ donation and KT vary by individual. CONCLUSIONS Our scoping review has identified potential barriers that Indigenous communities may face in accessing KT and LDKT. Further research is urgently needed to better understand barriers and support needs and to develop strategies to improve equitable access to KT and LDKT for Indigenous populations in Canada.

Abstract
Background: Living donor kidney transplantation (LDKT) is the treatment of choice for end stage renal disease. LDKT involves complex psychosocial issues, which remain partially unexplored. Methods: The study involved all potential living donors and recipient pairs consecutively referred for psychosocial evaluation from the nephrologist. Clinical and sociodemographic variables including prior psychiatric history, previous and current use of psychopharmacological therapy, motivation and information about the transplant procedure were collected. Study participants completed the Symptom Checklist-90-R (SCL-90-R) to assess psychopathological distress. Results: Fifty-three donor/recipient pairs underwent psychiatric and psychological evaluation. Seven subjects (13%) in the recipient group and 13 subjects (25%) in the donor group reported a history of psychological distress and/or psychiatric conditions. A psychiatric diagnosis was confirmed in 4 recipients (7.5% of the study sample, including autism spectrum disorder, histrionic personality disorder, and anxiety-depressive disorders) and 5 donors (9%, including narcissistic personality disorder in one case and anxiety-depressive disorders). SCL-90-R GSI mean scores were 0.3 ±0.3 and 0.2 ±0.2 for the recipient and donor groups, respectively. Overall, 8 couples (15%) suspended the living donation pathway before transplantation. Four couples were excluded for a new onset medical condition. The psychological and psychiatric evaluation excluded one candidate. One couple dropped out before completing the scheduled exams. One recipient refused to undergo crossover renal transplantation, while 1 donor candidate withdrew her consent for transplantation at the end of the evaluation process. Conclusions: Limited but significant psychopathological distress in donors and recipients supports the usefulness of psychiatric and psychological competencies within the transplant team.

Abstract
BACKGROUND Some studies reported the correlations between renal parenchymal stiffness measured by transient elastography or acoustic radiation force impulse (ARFI) and the extent of interstitial fibrosis. This study was prospectively designed to evaluate the correlation between clinical, histological findings and the kidney shear wave velocity (SWV, m/s) assessed by ARFI elastography to identify factors affecting the kidney SWV in normal patients. METHODS Seventy-three adult living kidney transplantation donors were enrolled in our center between September 2010 and January 2013. Before transplantation, all donors were evaluated by ARFI elastography to identify the range of SWV in kidneys. Time-zero biopsies were performed on all graft kidneys before implantation. RESULTS Mean age of donors was 42.0 ± 11.3 years. The mean SWV and depth were 2.21 ± 0.58 m/s and 5.37 ± 1.06 cm. All histological findings showed mild degree of the Banff score, only grade I. In univariate analyses, the SWV was not associated with all histological parameters. Age (r = -0.274, P = .019) diastolic blood pressure (DBP, r = -0.255, P = .030) and depth for SWV measurement (r = -0.345, P = .003) were significantly correlated with the SWV. In multivariate linear regression analysis, age, gender, body mass index (BMI), and depth for SWV measurement were significantly correlated with the SWV (P = .003, .005, .002, and .004, respectively). CONCLUSIONS We demonstrated that all histological findings are not correlated with the SWV of donor kidney. Otherwise, factors influencing the kidney SWV assessed by ARFI elastography are age, gender, BMI, and depth for the SWV measurement in donors for kidney transplantation.

Abstract
The evaluation and care of non-US citizen, non-US residents who wish to come to the United States to serve as international living kidney donors (ILKDs) can pose unique challenges. We surveyed US transplant programs to better understand practices related to ILKD care. We distributed the survey by email and professional society list-servs (Fall 2018, assessing 2017 experience). Eighty-five programs responded (36.8% program response rate), of which 80 considered ILKD candidates. Only 18 programs had written protocols for ILKD evaluation. Programs had a median of 3 (range: 0,75) ILKD candidates who initiated contact during the year, from origin countries spanning 6 continents. Fewer (median: 1, range: 0,25) were approved for donation. Program-reported reasons for not completing ILKD evaluations included visa barriers (58.6%), inability to complete evaluation (34.3%), concerns regarding follow-up (31.4%) or other healthcare access (28.6%), and financial impacts (21.4%). Programs that did not evaluate ILKDs reported similar concerns. Staff time required to evaluate ILKDs was estimated as 1.5-to-3-times (47.9%) or >3-times (32.9%) that needed for domestic candidates. Among programs accepting ILKDs, on average 55% reported successful completion of 1-year follow-up. ILKD evaluation is a resource-intensive process with variable outcomes. Planning and commitment are necessary to care for this unique candidate group.

Abstract
INTRODUCTION Renal artery fibromuscular dysplasia is generally considered a contraindication of kidney transplantation, since fibromuscular dysplasia occasionally induces hypertension or renal insufficiency in the recipient and/or donor. To date, limited information remains available with respect to whether kidneys with renal arterial fibromuscular dysplasia can be successfully transplanted. CASE PRESENTATION A 53-year-old potential donor was diagnosed with fibromuscular dysplasia of the right renal artery. Laparoscopic right nephrectomy was performed, and the affected portion was resected and reconstructed using the harvested internal iliac artery. Transplantation was successful and the serum creatinine level was <2 mg/dL for 3 years after surgery. CONCLUSION If reconstruction of the diseased artery could be safely performed, transplantation using a kidney from a donor with renal artery fibromuscular dysplasia may be considered.

Abstract
Anaphylaxis secondary to thymoglobulin (anti-thymocyte globulin) is a rare condition that can be life threatening. Thymoglobulin is a rabbit-derived T-cell depleting polyclonal immunoglobulin. It is commonly used for induction immunosuppression and/or for treatment of acute rejection in renal transplantation. We report a case of a living kidney transplant recipient who developed intraoperative anaphylactic shock secondary to thymoglobulin. The patient had a history of pet rabbit exposure. This case report highlights the importance of prompt identification and management of intraoperative anaphylaxis, which is key to a successful outcome. Induction immunosuppression selection based on patient characteristics is important. Communication between the anesthesia team and surgeons played a key role in stopping the donor surgery.

Abstract
We retrospectively compared the post-transplantation graft survival and the donor's estimated glomerular filtration rates (eGFRs) following living donor kidney transplantations (LDKTs) involving medically complex living donors (MCLDs) (the elderly and patients with obesity, hypertension, diabetes mellitus, or reduced renal function) and standard living donors (SLDs). The clinical data on patients who underwent LDKTs at our institution from 2006-2019, including 192 SLDs and 99 MCLDs, were evaluated. Regarding recipients, the log-rank test and multivariable Cox proportional hazards analyses showed a higher incidence of overall and death-censored graft loss in the recipients who received kidneys from MCLDs (Hazard ratio = 2.16 and 3.25, P = 0.015 and 0.004, respectively), after adjusting for recipient-related variables including age, sex, duration of dialysis, ABO compatibility, and donor-specific antibody positivity. Regarding donors, a linear mixed model showed significantly lower postdonation eGFRs (-2.25 ml/min/1.73 m2 , P = 0.048) at baseline in MCLDs than SLDs, but comparable change (difference = 0.01 ml/min/1.73 m2 /year, P = 0.97). In conclusion, although kidneys from MCLDs are associated with impaired graft survival, the donation did not adversely affect the MCLDs' renal health in at least the short-term. LDKTs involving carefully selected MCLDs would be an acceptable alternative for recipients with no SLDs.

Abstract
RATIONALE & OBJECTIVE Compared with recipients of blood group ABO-compatible (ABOc) living donor kidney transplants (LDKTs), recipients of ABO-incompatible (ABOi) LDKTs have higher risk for graft loss, particularly in the first few weeks after transplantation. However, the decision to proceed with ABOi LDKT should be based on a comparison of the alternative: waiting for future ABOc LDKTs (eg, through kidney paired exchange) or for a deceased donor kidney transplant (DDKT). We sought to evaluate the patient survival difference between ABOi LDKTs and waiting for an ABOc LDKT or an ABOc DDKT. STUDY DESIGN Retrospective cohort study of adults in the Scientific Registry of Transplant Recipients. SETTING & PARTICIPANTS 808 ABOi LDKT recipients and 2,423 matched controls from among 245,158 adult first-time kidney-only waitlist registrants who did not receive an ABOi LDKT and who remained on the waitlist or received either an ABOc LDKT or an ABOc DDKT, 2002 to 2017. EXPOSURE Receipt of ABOi LDKT. OUTCOME Death. ANALYTICAL APPROACH We compared mortality among ABOi LDKT recipients versus a weighted matched comparison population using Cox proportional hazards regression and Cox models that accommodated for changing hazard ratios over time. RESULTS Compared with matched controls, ABOi LDKT was associated with greater mortality risk in the first 30 days posttransplantation (cumulative survival of 99.0% vs 99.6%) but lower mortality risk beyond 180 days posttransplantation. Patients who received an ABOi LDKT had higher cumulative survival at 5 and 10 years (90.0% and 75.4%, respectively) than similar patients who remained on the waitlist or received an ABOc LDKT or ABOc DDKT (81.9% and 68.4%, respectively). LIMITATIONS No measurement of ABO antibody titers in recipients; eligibility of participants for kidney paired donation is unknown. CONCLUSIONS Transplant candidates who receive an ABOi LDKT and survive more than 180 days posttransplantation experience a long-term survival benefit compared to remaining on the waitlist to potentially receive an ABOc kidney transplant.

Abstract
End-stage kidney disease patients in the United States may have family members or friends who are not US citizens or residents but are willing to serve as their living kidney donor in the United States ("international donors"). In July 2017, the American Society for Transplantation (AST) Live Donor Community of Practice (LDCOP) convened a multidisciplinary workgroup of experts in living donation care, including coordinators, social workers, donor advocates, administrators, and physicians, to evaluate educational gaps related to the evaluation and care of international donors. The evaluation of international living donor candidates is a resource-intensive process that raises key considerations for assessing risk of exploitation/inducement and addressing communication barriers, logistics barriers, and access to care in their home country. Through consensus-building discussions, we developed recommendations related to: (a) establishing program guidelines for international donor candidate evaluation and selection; (b) initial screening; (c) logistics planning; (d) comprehensive evaluation; and (e) postdonation care and follow-up. These recommendations are not intended to direct formal policy, but rather as guidance to help programs more efficiently and effectively structure and execute evaluations and care coordination. We also offer recommendations for research and advocacy to optimize the care of this unique group of living donors.

Abstract
The effects of hyperchloremia on kidney grafts have not been investigated in patients undergoing living-donor kidney transplantation (LDKT). In this study, data from 200 adult patients undergoing elective LDKT between January 2016 and December 2017 were analyzed after propensity score (PS) matching. The patients were allocated to hyperchloremia and non-hyperchloremia groups according to the occurrence of hyperchloremia (i.e., ≥110 mEq/L) immediately after surgery. Poor early graft recovery was defined as estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m2 during the first 48 hours after surgery. After PS matching, no significant differences in perioperative recipient or donor graft parameters were observed between groups. Although the total amount of crystalloid fluid infused during surgery did not differ between groups, the proportions of main crystalloid fluid type used (i.e., 0.9% normal saline vs. Plasma Solution-A) did. The eGFR increased gradually during postoperative day (POD) 2 in both groups. However, the proportion of patients with eGFR > 60 mL/min/1.73 m2 on POD 2 was higher in the non-hyperchloremia group than in the hyperchloremia group. In this PS-adjusted analysis, hyperchloremia was significantly associated with poor graft recovery on POD 2. In conclusion, exposure to hyperchloremia may have a negative impact on early graft recovery in LDKT.

Abstract
Although remote ischemic preconditioning (RIPC) has been shown to have renoprotective effects, few studies have assessed the effects of RIPC on renal function in living kidney donors. This study investigated whether RIPC performed in living kidney donors could improve residual renal function in donors and outcomes in recipients following kidney transplantation. The donors were randomized into a control group (n = 85) and a RIPC group (n = 85). The recipients were included according to the matched donors. Serum creatinine (sCr) concentrations and estimated glomerular filtration rate (eGFR) were compared between control and RIPC groups in donors and recipients. Delayed graft function, acute rejection, and graft failure within one year after transplantation were evaluated in recipients. sCr was significantly increased in the control group (mean, 1.13; 95% confidence interval (CI), 1.07–1.18) than the RIPC group (1.01; 95% CI, 0.95–1.07) (p = 0.003) at discharge. Donors with serum creatinine >1.4 mg/dL at discharge had higher prevalence of chronic kidney disease (n = 6, 26.1%) than donors with a normal serum creatinine level (n = 8, 5.4%) (p = 0.003) after one year. sCr concentrations and eGFR were similar in the RIPC and control groups of recipients over the one-year follow-up period. Among recipients, no outcome variables differed significantly in the RIPC and control groups. RIPC was effective in improving early renal function in kidney donors but did not improve renal function in recipients.

Abstract
BACKGROUND Living donor kidney transplantation (LDKT) has several advantages over deceased donor kidney transplantation. Yet rates of living donation are declining in Canada and there exists significant interprovincial variability. Efforts to improve living donation tend to focus on the patient and barriers identified at their level, such as not knowing how to ask for a kidney or lack of education. These efforts favor those who have the means and the support to find living donors. Thus, a Canadian Institutes of Health Research (CIHR)-organized workshop recommended that education efforts to understand and remove barriers should focus on health professionals (HPs). Despite this, little attention has been paid to what they identify as barriers to discussing LDKT with their patients. OBJECTIVE Our aim was to explore HP-identified barriers to discuss living donation with patients in 3 provinces of Canada with low (Quebec), moderate (Ontario), and high (British Columbia) rates of LDKT. DESIGN This study consists of an interpretive descriptive approach as it enables to move beyond description and inform clinical practice. SETTING Purposive criterion and quota sampling were used to recruit HPs from Quebec, Ontario, and British Columbia who are involved in the care of patients with kidney disease and/or with transplant coordination. PATIENTS Not applicable. MEASUREMENTS Semistructured interviews were conducted. The interview guide was developed based on a preliminary analytical framework and a review of the literature. METHODS Thematic analysis was used to analyze the data stemming from the interviews. The coding process comprised of a deductive and inductive approach, and the use of a qualitative analysis software (NVivo 11). Following this, themes were identified and developed. Interviews were conducted until thematic saturation was obtained. In total, we conducted 16 telephone interviews as thematic saturation was attained. RESULTS Six predominant themes emerged: (1) lack of communication between transplant and dialysis teams, (2) absence of referral guidelines, (3) role perception and lack of multidisciplinary involvement, (4) HP's lack of information and training, (5) negative attitudes of some HP toward LDKT, (6) patient-level barriers as defined by the HP. HPs did mention patients' attitudes and some characteristics as the main barriers to discussions about living donation; this was noted in all provinces. HPs from Ontario and British Columbia indicated multiple strategies being implemented to address some of these barriers. Those from Ontario mentioned strategies that center on the core principles of provincial-level standardization, while those from British Columbia center on engaging the entire multidisciplinary team and improved role perception. We noted a dearth of such efforts in Quebec; however, efforts around education and promotion, while tentative, have emerged. LIMITATIONS Social desirability and selection bias. Our analysis might not be applicable to other provinces. CONCLUSIONS HPs involved with the referral and coordination of transplantation play a major role in access to LDKT. We have identified challenges they face when discussing living donation with their patients that warrant further assessment and research to inform policy change.

Abstract
Baseline predonation estimated GFR (eGFR) appears to predict the risk of postdonation chronic kidney disease in live donors. New KIDGO guidelines recommend an eGFR ≥90 ml/min/1.73 m2 as an acceptable level of glomerular filtration rate (GFR) for kidney donation. In the Australian Paired Kidney Exchange (AKX) program, all donors with a raw measured GFR (mGFR) ≥80 ml/min are deemed suitable for donation, but the significance of this selection indicator is unclear. We analysed the first 129 live donors in the AKX program with at least 1-year follow-up linking records in the AKX database and ANZDATA. There were 73 male and 56 female donors; mean (±SD) age was 53 ± 11 years. Predonation eGFR was 94 ± 13 ml/min/1.73 m2 , mGFR 99 ± 17 ml/min/1.73 m2 and raw mGFR 108 ± 18 ml/min. Baseline eGFR was <80 ml/min/1.73 m2 in 19 donors, and <90 ml/min/1.73 m2 in 42 donors. At 1 year postdonation eGFR was 68 ± 15 ml/min/1.73 m2 and the predicted eGFR at 30 years postdonation was on average 50 (29-83) ml/min/1.73 m2 . The hypothetical mean age at end-stage kidney disease was estimated to be 145 (95% CI 120-263) years. Over 30% of AKX live donors would have been excluded from donation using KDIGO guidelines. Using AKX donor guidelines, the majority of donors with predicted eGFR <30 ml/min/1.73 m2 30-year postdonation were aged ≥50 years. Long-term outcome data on AKX donors with low eGFR will need careful monitoring.

Abstract
BACKGROUND During kidney transplantation, intraoperative fluid management can affect post-transplant graft function. It is unclear whether or not central venous pressure (CVP) monitoring is required to guide fluid therapy during kidney transplantation. METHODS We compared post-transplant graft function in recipients of living donor kidney transplants between August 2006 and March 2009 based on the use or absence of intraoperative CVP monitoring. Graft function, assessed using the creatinine reduction ratio on postoperative day 2 (CCR2), was evaluated by multivariable linear regression analysis and in a propensity-matched cohort. RESULTS Two hundred and ninety patients were included in the analysis. Central venous pressure was monitored in 84 patients (29%). There was no difference in post-transplant graft function, as measured by CCR2, between patients with and without CVP monitoring in both unadjusted and multivariable-adjusted analyses. There were also no statistically significant differences in CCR2, delayed graft function, or 3-month renal function between those monitored with CVP and those without, in the propensity-matched cohort. CONCLUSIONS In this single-center analysis, immediate post-transplant renal function was not associated with the use of intraoperative CVP monitoring.

Abstract
Introduction Despite the different assays available for immune-risk stratification before living-donor kidney transplantation (LDKT), the precise type and number of tests to perform remain uncertain. Methods In a cohort of 330 consecutive LDKT patients, all of which were complement-dependent cytotoxicity (CDC)−crossmatch negative, we retrospectively analyzed the impact on main clinical outcomes of most sensitive immunoassays (complement-dependent cytotoxicity−panel-reactive antibody [CDC-PRA], flow cytometry crossmatch [FC-XM], donor-specific antibodies [DSAs], and their complement-binding capacity DSA-C3d]), together with donor/recipient HLA eplet matching. Mean follow-up was 67 months (range 24−190 months). Results Of 330 patients, 35 (11%) showed a CDC-PRA >20%; 17 (5%) FC-XM+; 30 (9%) DSA+, 18(5%) DSA-C3d+, with low overlapping results (10 patients positive in all donor-specific tests). Unlike HLA allele compatibility, the mean number of HLA class II eplet mismatches was higher in LDKT patients with positive baseline test results. DSA-C3d+ showed higher mean fluorescence intensity (MFI) DSA, with a cut-off MFI of 6192 accurately predicting complement fixation (area under the curve = 0.85, P = 0.008). Although all assays were associated with acute rejection (AR), only DSA-C3d+ (odds ratio [OR] = 6.64, P = 0.038) or high MFI-DSA (OR = 7.54, P = 0.038) independently predicted AR. Likewise, poorly HLA class II eplet−matched patients were at higher risk for AR, particularly patients with negative baseline test results (OR = 1.14, P = 0.019). Finally, previous AR and FC-XM+/DSA+, regardless of C3d positivity, independently predicted graft loss. Conclusion Combining FC-XM and solid-phase assays with the evaluation of donor/recipient HLA eplet mismatches, are most accurate tools for immune-risk stratification prior LDKT.

Abstract
This review is intended to be a guide for the physician to evaluate and prepare a donor / recipient couple for living kidney transplantation. Although it is intended to be exhaustive, it will not be able to respond at all possible and different cases, but it may apply at most of them. Renal transplantation is considered the choice treatment for patients with chronic renal failure and if the kidney transplant is performed pre-emptive it is associated with better organ and patient survival. The main aim of the program is to evaluate the risks of donor and recipient and to ensure the donor safety and well-being. Eligibility for living transplant can only be granted when the risks are acceptable, well defined and the couple is adequately informed. The review includes clinical and legal procedures needed to transplantation. Early conditions that contraindicate the transplant must be removed, to avoid unnecessary exams, excessive waste of time, money. The sequence of the exams has been ordered so that costly and invasive surveys are carried out only after other simple and essential investigations have confirmed the transplant suitability. Special attention should be paid to the renal function measurement, proteinuria, hematuria, hypertension, obesity, pre diabetes, renal calculus, and cancers. To give eligibility for living transplant is often not easy, but a careful study can avoid many complications and improve the transplant outcome.

Abstract
OBJECTIVE To compare transplant outcomes among elderly (aged ≥60 years) and non-elderly recipients, and to evaluate the acceptability of elderly living donor kidney transplantation in practice after consideration of living donor type. METHODS We included 830 adult patients with living donor kidney transplantation between 2000 and 2011 in this retrospective cohort study. We compared death-censored graft survival, patient survival, biopsy-proven rejection, complications, and renal function in elderly (n = 119) and non-elderly recipients (n = 278). RESULTS There was no significant difference in 10-year death-censored graft survival (P = 0.980). Corresponding patient survival rates in the elderly and non-elderly groups were 84.1% and 98.1%, respectively (hazard ratio 6.15, 95% confidence interval 2.12-17.82, P < 0.001). Elderly patients had more complications and chronic T-cell-mediated rejection. Factors associated with death in elderly recipients with functioning grafts were residual advanced recipient age (hazard ratio 1.39), decreased hemoglobin (hazard ratio 4.10), hepatitis B virus (hazard ratio 7.89), hepatitis C virus (hazard ratio 13.12) and elevated alanine aminotransferase (hazard ratio 1.13). CONCLUSIONS Elderly living donor kidney transplantation seems to provide adequate acceptable outcomes. However, physicians should be cautious when evaluating elderly patients with hepatitis, and further studies are required to improve long-term outcomes.

Abstract
Background To ascertain the validity of kidney paired donations (KPDs) as an alternative strategy for increasing living donor kidney transplantations (LDKTs) in an LDKT-dominated transplant programme since directed kidney transplantation, ABO-incompatible or crossmatch-positive pairs are not feasible due to costs and infectious complications. Methods This was a prospective single-centre study of 77 KPD transplantations (25 two-way, 7 three-way and 1 six-way exchange) from 1 January 2015 to 1 January 2016 of 158 registered donor recipient pairs. During this period, a total of 380 kidney transplantations [71 deceased donor kidney transplantations (DDKTs), 309 LDKTs] were performed. The reasons for opting for KPD were ABO incompatibility (n = 45), sensitization (n = 26) and better matching (n = 6). Results KPD matching was facilitated in 62% (n = 98) of transplants. In all, 48.7% (n = 77) of the transplants were completed in 2015, whereas 13.3% (n = 21) of the matched patients were to undergo transplant surgery in early 2016 after getting legal permission. The waiting time for KPD was shorter compared with DDKT. The death-censored graft survival and patient survival were 98.7% (n = 76) and 93.5% (n = 72), respectively. In all, 14.2% (n = 11) of patients had acute rejection. Match rates among sensitized (n = 60) and O group patients (n = 62) were 58.3% (n = 35) and 41.9% (n = 26), respectively. Of these, 43.3% (n = 26) and 29% (n = 18) of transplants were completed and 15% (n = 9) and 12.9% (n = 8), respectively, are waiting for legal permission. Conclusions LDKT increased by 25% in 1 year in our single-centre KPD programme. Our key to success was the formation of a KPD registry, awareness and active counselling programs and developing a dedicated team.

Abstract
In a living donor kidney transplantation (LDKT) dominated transplant programme, kidney paired donation (KPD) may be a cost-effective and valid alternative strategy to increase LDKT in countries with limited resources where deceased donation kidney transplantation (DDKT) is in the initial stages. Here, we report our experience of 300 single-centre KPD transplantations to increase LDKT in India. Between January 2000 and July 2016, 3616 LDKT and 561 DDKT were performed at our transplantation centre, 300 (8.3%) using KPD. The reasons for joining KPD among transplanted patients were ABO incompatibility (n = 222), positive cross-match (n = 59) and better matching (n = 19). A total of 124 two-way (n = 248), 14 three-way (n = 42), one four-way (n = 4) and one six-way exchange (n = 6) yielded 300 KPD transplants. Death-censored graft and patient survival were 96% (n = 288) and 83.3% (n = 250), respectively. The mean serum creatinine was 1.3 mg/dl at a follow-up of 3 ± 3 years. We credit the success of our KPD programme to maintaining a registry of incompatible pairs, counselling on KPD, a high-volume LDKT programme and teamwork. KPD is legal, cost effective and rapidly growing for facilitating LDKT with incompatible donors. This study provides large-scale evidence for the expansion of single-centre LDKT via KPD when national programmes do not exist.

Abstract
In living donor transplantation, cold ischemia time is a concern in transplants involving kidney paired donation. The impact of cold ischemia time over eight hours is unknown. Here we examined the association of cold ischemia time with delayed graft function and allograft loss among 48,498 living recipients in the Scientific Registry of Transplant Recipients registry. The incidence of delayed graft function was low but significantly higher among patients with longer cold ischemia times (0-2.0 hours: 3.3%; 2.1-4.0 hours: 3.9%; 4.1-8.0 hours: 4.3%; 8.1-16.0 hours: 5.5%). In multivariate analyses, only those with cold ischemia times of 8.1-16.0 hours had increased odds of delayed graft function (odds ratio 1.47; 95% confidence interval 1.05-2.05) compared to patients with times of 0-2.0 hours. In multivariate time-to-event analyses, cold ischemia times of 16 hours or less were not associated with allograft loss from any cause including death or death-censored graft loss with hazard ratios for cold ischemia times between 8.0-16.0 hours of 0.97 (95% confidence interval 0.74-1.26) and 1.09 (0.81-1.48) compared to patients with times of 0-2.0 hours). The results were consistent in paired and non-kidney paired donation transplants and in those with living donors over 50 years of age. In subgroup analysis restricted to kidney paired donation recipients, there was no difference in the risk of delayed graft function with an odds ratio of 1.40 (0.88, 2.40) or all-cause graft loss with a hazard ratio of 0.89 (0.62, 1.30) in transplant recipients who received kidneys that were shipped versus not shipped. Thus, a cold ischemia time up to 16 hours has limited impact on living donor outcomes. These findings may help expand living donor transplantation through kidney paired donation.

Abstract
Among adults, living donor kidney transplant rates began declining in the United States after 2004 but whether a similar decline is occurring in the pediatric candidates has not been well studied. Share 35, a change in allocation rules implemented in October of 2005, may also have influenced rates of living donation. We sought to determine whether a decline in rates was occurring in pediatric candidates and whether the Share 35 program was the cause of the decline. All children listed for a kidney transplant or transplanted with a living donor without listing between 1996 and 2011 were identified in the United States (N=14 911) of which 6046 had received a living donor transplant during follow-up. Kaplan-Meier analysis showed a decline in living donor rates in candidates listed after 2001. Logistic regression analysis for living donor kidney transplantation confirmed the timing of the drop but also showed that changes in candidate demographics and center listing practices were impacting rates. A large drop in parental donation was the main cause for the drop. The rate of living donor transplant among pediatric candidates declined after 2001 predating by 4 years the implementation of Share 35, suggesting that factors other than changes in allocation rules are responsible for the decline.

Abstract
PURPOSE OF REVIEW For the more than 636,000 adults with end-stage renal disease (ESRD) in the U.S., kidney transplantation is the preferred treatment compared to dialysis. Living donor kidney transplantation (LDKT) comprised 31% of kidney transplantations in 2015, an 8% decrease since 2004. We aimed to summarize the current literature on decision aids that could be used to improve LDKT rates. RECENT FINDINGS Decision aids are evidence-based tools designed to help patients and their families make difficult treatment decisions. LDKT decision aids can help ESRD patients, patients' family and friends, and healthcare providers engage in treatment decisions and thereby overcome multifactorial LDKT barriers. SUMMARY We identified 12 LDKT decision aids designed to provide information about LDKT, and/or to help ESRD patients identify potential living donors, and/or to help healthcare providers make decisions about treatment for ESRD or living donation. Of these, 4 were shown to be effective in increasing LDKT, donor inquiries, LDKT knowledge, and willingness to discuss LDKT. Although each LDKT decision aid has limitations, adherence to decision aid development guidelines may improve decision aid utilization and access to LDKT.

Abstract
BACKGROUND Due to its high sensitivity, the flow cytometry cross-match (FCXM) has been described as valuable tool for identifying an optimal donor. We here focused on the impact of ABO incompatibility on FCXM results. METHODS We analyzed 29 ABO incompatible and 89 ABO compatible donor-recipient pairs (73 and 175 datasets, respectively) prior to living donor kidney transplantation. In all patients, lymphocytotoxic cross-matches for B and T cells were negative. RESULTS Recipients with blood group O (A to O and B to O) displayed significantly (P < 0.05) higher T-FCXM results than those with blood group A and B (A to B, B to A and AB to A), respectively. Donor-specific T-FCXM responses (ΔMFI values) were significantly higher (P < 0.05) in ABO incompatible vs. compatible pairs (ABO incompatible recipients with blood group O: 32 ± 6; with blood group A: 19 ± 7; with blood group B: 7 ± 4; recipients with ABO compatibility: 3 ± 2, respectively, data represent mean ± SEM). Consistent with the T-FCXM results donor-specific isohemagglutinins (IgG titers) were significantly higher in recipients with blood group O vs. A, both prior to rituximab treatment and plasmapheresis/immune adsorption (P = 0.004) and immediately prior to transplantation, i.e., after rituximab and antibody-depleting therapies (P = 0.04). CONCLUSIONS ABO incompatibility was associated with higher T-FCXM responses, especially in recipients with blood group O. This finding has major impact on the interpretation of flow cross-match results. Current cut-off values need to be reassessed in the ABO incompatible setting. © 2016 International Clinical Cytometry Society.

Abstract
BACKGROUND The Australian kidney paired donation program adopted the principles of within-chain simultaneous live donor surgery and of organ transport, with the requirement of keeping cold ischemia time (CIT) to <12 h. Whether these principles could be adhered to and what impact on transplant outcome they might have is unknown. METHODS We evaluated the logistic challenges and outcomes of the first 100 kidney transplants performed in the Australian kidney paired donation program. RESULTS Within 4 years, 17 donor surgeons at 12 centres were involved in 37 chain exchange surgeries. Sixteen kidneys were transplanted at the same hospital and 84 required transport to the recipient hospital. Mean (±SD) within chain anaesthetic induction time variability was 8 ± 18 min and mean individual surgeon operating time was 115 ± 44 min. In two cases, delays during donor surgery resulted in increased CIT by 1 h because of deferred transport. CIT was 2.6 ± 0.6 h for non-shipped and 6.8 ± 2.8 h for shipped kidneys, four kidneys had CIT of 12-14 h. Immediate allograft function was observed in 85% of recipients, with no difference between shipped and non-shipped kidneys. There were only two cases of delayed graft function requiring temporary dialysis; both had CIT <7 h. There was no difference in serum creatinine at 1 month between non-shipped and shipped kidneys (105 ± 26 versus 112 ± 50 µmol/L) and allograft survival at 1 year was 97%. CONCLUSION The study provided a favourable audit of kidney transplant activity, despite challenges of simultaneous surgery, organ transport coordination and prolonged CIT. The decision to ship donor kidneys rather than the donor was demonstrated to be feasible and safe.

Abstract
Patients with end-stage renal disease (ESRD) show characteristic abnormalities in cardiac structure and function. We evaluated the influence of these abnormalities on adverse cardiopulmonary outcomes after living donor kidney transplantation in patients with valid preoperative transthoracic echocardiographic evaluation. We then observed any development of major postoperative cardiovascular complications and pulmonary edema until hospital discharge. In-hospital major cardiovascular complications were defined as acute myocardial infarction, ventricular fibrillation/tachycardia, cardiogenic shock, newly-onset atrial fibrillation, clinical pulmonary edema requiring endotracheal intubation or dialysis. Among the 242 ESRD study patients, 9 patients (4%) developed major cardiovascular complications, and 39 patients (16%) developed pulmonary edema. Diabetes, ischemia-reperfusion time, left ventricular end-diastolic diameter (LVEDd), left ventricular mass index (LVMI), right ventricular systolic pressure (RVSP), left atrium volume index (LAVI), and high E/E' ratios were risk factors of major cardiovascular complications, while age, LVEDd, LVMI, LAVI, and high E/E' ratios were risk factors of pulmonary edema. The optimal E/E' cut-off value for predicting major cardiovascular complications was 13.0, showing 77.8% sensitivity and 78.5% specificity. Thus, the patient's E/E' ratio is useful for predicting in-hospital major cardiovascular complications after kidney transplantation. We recommend that goal-directed therapy employing E/E' ratio be enacted in kidney recipients with baseline diastolic dysfunction to avert postoperative morbidity.

Abstract
New approaches to increase kidney transplantation rates through expansion of live donor kidney transplantation have become necessary due to ongoing shortage of deceased donor organs. These strategies include desensitization in antibody-incompatible transplants to overcome the barrier of blood group incompatibility or human leucocyte antigen antibodies between recipient and donor and kidney paired donation (KPD) programmes. In KPD, a kidney transplant candidate with an incompatible live donor joins a registry of other incompatible pairs in order to find potentially compatible transplant solutions. To match the largest possible number of donor-recipient pairs while minimizing immunologic risk, KPD programmes use sophisticated algorithms to identify suitable matches with simultaneous two-way or more complex multi-way exchanges as well as including non-directed anonymous donors to start a chain of compatible transplantations. Because of the significant immunologic barriers when fewer donor options are available, the optimal solution for difficult-to-match, highly sensitized patients is access to more potential donors using large multi-centre or national KPD registries. This review focuses on the first 4 years of experience with the Australian multi-centre KPD programme that was established in October 2010.

Abstract
BACKGROUND Laparoscopic donor nephrectomy may convert short main arteries into multiple arteries, increasing the technical challenge of implantation. We evaluated our experience to identify factors predictive of multiple arteries after laparoscopic nephrectomy. METHODS All laparoscopic nephrectomies from the start of our program in November 2002 until June 2013 were studied, and preoperative imaging reviewed for donor artery length and multiplicity together with operative findings. RESULTS A total of 287 consecutive laparoscopic live donor nephrectomies (64 right and 223 left nephrectomies) were studied. Renal artery length was measured from preoperative donor magnetic resonance or computed tomography angiogram and nephrectomy performed using a laparoscopic stapling device. Nine left kidneys with a single artery (6, 7, 9, 10, 11, 12, 13, 14, and 16 mm in length) and five right kidneys with a single artery (5, 13, 15, 20, and 26 mm) on imaging resulted in multiple renal arteries at implantation. Complex renal vein anatomy was associated with multiple arteries following retrieval. CONCLUSION A main renal artery length of more than 16 mm on the left and 26 mm on the right is unlikely to result in multiple arteries to implant. The possibility of multiple arteries should be borne in mind when the donor renal artery is short.

Abstract
OBJECTIVES There are multiple barriers to kidney transplantation from a living donor for patients. A critical factor is their own approach to pursuing opportunities for transplantation, including their preferences for living or deceased donation and their concerns about living donation. As part of a wider study into barriers to living donor transplantation in New Zealand, our aim was to examine the preferences and concerns of New Zealand patients who are waiting for kidney transplantation. METHODS Mixed methods were used, incorporating a mailed survey of patients on the waiting list for a deceased donor transplant, followed by in-depth semi-structured interviews. The survey included questions about preferences for living or deceased donation, willingness to accept a kidney from a potential donor if offered and concerns about aspects of living donation. Responses were received from 193 (38.2%) patients. These issues were explored in more depth in follow-up interviews with 17 patients. RESULTS The majority of patients were positive about living donor transplantation with only a few actively preferring a deceased donor. The vast majority would accept an offer from a potential donor. Donors being financially out-of-pocket and being upset if the transplant failed were the highest ranked concerns. Impacts on donor health were also a significant concern for patients. Positive views about living donor transplantation and stated willingness to accept offers could be undermined by deep, unresolved concerns and could result in patients declining offers from potential donors. Being well-informed about the risks to donors and having confidence in the donor evaluation process were important for reducing patients' concerns. CONCLUSIONS The preferences and concerns of patients in New Zealand are similar to those reported elsewhere. Education needs to address the concerns of patients and ensure they have accurate knowledge about living donation. Concerns about financial impacts on donors, however, arise from New Zealand's policy of not fully reimbursing living donors for lost income and cannot be addressed through improved education.

Abstract
Living donor kidney transplantation is the preferred treatment for patients suffering from end-stage renal disease. To alleviate the shortage of kidney donors, many advances have been made to improve the utilization of living donors deemed incompatible with their intended recipient. The most prominent of these advances is kidney paired donation (KPD), which matches incompatible patient-donor pairs to facilitate a kidney exchange. This review discusses the various approaches to matching and allocation in KPD. In particular, it focuses on the underlying principles of matching and allocation approaches, the combination of KPD with other strategies such as ABO incompatible transplantation, the organization of KPD, and important future challenges. As the transplant community strives to balance quantity and equity of transplants to achieve the best possible outcomes, determining the right long-term allocation strategy becomes increasingly important. In this light, challenges include making full use of the various modalities that are now available through integrated and optimized matching software, encouragement of transplant centers to fully participate, improving transplant rates by focusing on the expected long-run number of transplants, and selecting uniform allocation criteria to facilitate international pools.

Abstract
BACKGROUND Recipients of ABO-incompatible (ABOi) living-donor kidney transplants often undergo more intense immunosuppression than their ABO-compatible counterparts. It is unknown if this difference leads to higher cancer risk after transplantation. Single-center studies are too small and lack adequate duration of follow-up to answer this question. METHODS We identified 318 ABOi recipients in the Transplant Cancer Match Study, a national linkage between the Scientific Registry of Transplant Recipients and population-based U.S. cancer registries. Seven cancers (non-Hodgkin lymphoma, Merkel cell carcinoma, gastric adenocarcinoma, hepatocellular carcinoma, thyroid cancer, pancreatic cancer, and testicular cancer) were identified among ABOi recipients. We then matched ABOi recipients to ABO-compatible controls by age, gender, race, human leukocyte antigen mismatch, retransplantation, and transplant year. RESULTS There was no demonstrable association between ABOi and cancer in unadjusted (incidence rate ratio, 0.83; 95% confidence interval, 0.33-1.71; P=0.3) or matched control (incidence rate ratio, 0.99; 95% confidence interval, 0.38-2.23; P=0.5) analyses. CONCLUSION To the extent that could be determined in this registry study, current desensitization protocols are not associated with increased risk of cancer after transplantation.

Abstract
In the United States, racial-ethnic minorities experience disproportionately high rates of ESRD, but they are substantially less likely to receive living donor kidney transplants (LDKT) compared with their majority counterparts. Minorities may encounter barriers to LDKT at several steps along the path to receiving it, including consideration, pursuit, completion of LDKT, and the post-LDKT experience. These barriers operate at different levels related to potential recipients and donors, health care providers, health system structures, and communities. In this review, we present a conceptual framework describing various barriers that minorities face along the path to receiving LDKT. We also highlight promising recent and current initiatives to address these barriers, as well as gaps in initiatives, which may guide future interventions to reduce racial-ethnic disparities in LDKT.
