Abstract
BACKGROUND The number of marginal living kidney donors has increased. Medically complex donors who have hypertension, older age, or low estimated glomerular filtration rate (eGFR) have been more likely to be used. METHODS We conducted a retrospective cohort study of living kidney donors at a single center. We analyzed 309 living donors and divided them into three groups: group with older donors (aged ≥70 years) (n = 41), middle-aged (aged 46-69 years) (n = 239), and young donors (aged <46 years) (N = 29). Donor factors associated with chronic kidney disease (CKD) stage 3b or worse within 5 years post-donation were investigated. RESULTS Of the 309 live donors, 86 (27.8%) developed CKD stage3b or worse within 5 years post-donation. The incidence of CKD stage3b or worse within 5 years post-donation was significantly higher in older donor (p < 0.01). Cox regression models revealed that older donor ages and lower eGFR were significantly related to the development of CKD stage3b or worse, independent of comorbidities such as obesity and hypertension [hazard ratio (95% CI); 4.59 (1.02-20.6), p = 047, 0.95 (0.94-0.96), p ≤ 0.01, respectively]. However, recovery of eGFR 4-5 years after donation was noted in the middle-aged and older donor groups, whereas the level of eGFR remained unchanged in the young group. CONCLUSIONS Older donors tend to develop CKD stage3b within 5 years post-donation but with the potential of recovery. Healthy older people (aged ≥70 years) could be candidates for living donors under careful monitoring of kidney function after donation.

Abstract
BACKGROUND AND OBJECTIVES End-stage renal disease (ESRD) rates are on the rise globally, including in India. However, the affordability of dialysis treatment remains a significant challenge for many, with costs varying across different regions. Although cost-effective, kidney transplantation faces challenges like a surgeon shortage, lack of infrastructure, and lack of logistic support. The study examines Indian laparoscopic nephrectomy outcomes and their benefits for donor recovery. It covers kidney donor procedural details, demographics, preoperative health evaluations, complications, and one-month follow-up. METHODS Ethical approval was obtained, and the study involved 102 cases at the Indira Gandhi Institute of Medical Science, Patna, Bihar, India, from 2019 to 2023. Detailed preoperative assessments, postoperative complications, and one-month follow-up analyses were conducted. Statistical analysis employed SPSS version 17 (IBM Corp., Armonk, NY). RESULTS The results revealed an average surgery time of 152.3 min, blood loss of 205 ± 42 ml, and a hospital stay of 4.6 ± 2.2 days. The study found a female predominance (80.39%), with a mean donor age of 35.9 ± 5.2 years. Preoperative assessments showed robust patient health, with glomerular filtration rate (GFR) exceeding the expected threshold and normal urea levels, creatinine, electrolytes, liver enzymes, bilirubin, albumin, and total protein. Post-nephrectomy complications were reported, with females experiencing more difficulties than males. CONCLUSION This study underscores the efficiency and safety of laparoscopic nephrectomy in the Indian context, providing valuable insights into donor demographics, preoperative health assessments, complications, and postoperative outcomes. The findings contribute to understanding laparoscopic nephrectomy outcomes and associated risk factors despite certain limitations.

Abstract
OBJECTIVES Kidney transplant is the best treatment for patients with end-stage kidney disease. In many regions of the world, including the Middle East, most kidney transplants are from living donors. In contrast to recipients, data for living donors remain scarce. Here, we describe living donor baseline characteristics at first hospital check at a single center in Baghdad, Iraq. MATERIALS AND METHODS We collected and analyzed demographic, laboratory, imaging, and histocompatibility data from donor records at the Nephrology and Renal Transplantation Center, Medical City-Baghdad, Baghdad, Iraq, from July 2022 to September 2022. RESULTS We included 124 kidney donors (56.4% male) who donated their kidneys 1 to 3 years previous to our study, with a mean age of 34.84 ± 10.04 years and mean body mass index (weight in kilograms divided by height in meters squared) of 27.11 ± 2.12. Most donors donated their kidneys to a firstdegree relative (69.2%); blood group O was the most prevalent (47.5%). More than half of the donors were unemployed. Histocompatibility testing showed that 40% of the donors had >3 human leukocyte antigen mismatches with their recipients, and 30% of the recipients were high-risk sensitized patients with a calculated panel reactive antibody >50%. Regarding the virus status, 68.5% of the donors tested positive for cytomegalovirus immunoglobulin G, 8% of the transplants were high-risk cytomegalovirus status, and 43.5% tested positive for Epstein-Barr virus immunoglobulin G. Renal imaging showed that 75.8% of donors had a single artery and 24.1% had a double artery (26.6% double left, 40% double right, and 33.3% both). CONCLUSIONS For living transplant procedures at a single center in Iraq, most were from related donors. Most donors are unemployed, which mandates future health and social support. High immunological and viral risks must not be ignored in a single center with living related donors.

Abstract
BACKGROUND Bariatric surgery (BS) is the optimal approach for sustained weight loss and may alter donation candidacy in potential donors with obesity. We evaluated the long-term effects of nephrectomy after BS on metabolic profile, including body mass index, serum lipids and diabetes, and kidney function of donors. METHODS This was a single-center retrospective study. Live kidney donors who underwent BS before nephrectomy were matched for age, gender, and body mass index with patients who underwent BS alone and with donors who underwent nephrectomy alone. Estimated glomerular filtration rate (eGFR) was calculated according to Chronic Kidney Disease Epidemiology Collaboration and adjusted to individual body surface area to create absolute eGFR. RESULTS Twenty-three patients who underwent BS before kidney donation were matched to 46 controls who underwent BS alone. At the last follow-up, the study group showed significantly worse lipid profile with low-density lipoprotein of 115 ± 25 mg/dL versus the control group with low-density lipoprotein of 99 ± 29 mg/dL ( P = 0.036) and mean total cholesterol of 191 ± 32 versus 174 ± 33 mg/dL ( P = 0.046). The second control group of matched nonobese kidney donors (n = 72) had similar serum creatinine, eGFR, and absolute eGFR as the study group before nephrectomy and 1 y after the procedure. At the end of follow-up, the study group had significantly higher absolute eGFR compared with the control group (86 ± 21 versus 76 ± 18 mL/min; P = 0.02) and similar serum creatinine and eGFR. CONCLUSIONS BS before live kidney donation is a safe procedure that could increase the donor pool and improve their health in the long run. Donors should be encouraged to maintain their weight and avoid adverse lipid profile and hyperfiltration.

Abstract
BACKGROUND Renal artery thrombosis is a devastating complication if not detected early. Cardioembolic disease or surgical and technical complications are frequent causes of renal artery thrombosis. There are some reports of renal artery thrombosis in a renal allograft, but to our knowledge, this is the first case of renal artery thrombosis reported in a kidney donor.

Managing the Costs of Routine Follow-up Care After Living Kidney Donation: a Review and Survey of Contemporary Experience, Practices, and Challenges. CURRENT TRANSPLANTATION REPORTS 2022; 9:328-335. [PMID: 36187071 PMCID: PMC9510404 DOI: 10.1007/s40472-022-00379-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 08/12/2022] [Indexed: 11/12/2022]
Abstract
Purpose of Review While living organ donor follow-up is mandated for 2 years in the USA, formal guidance on recovering associated costs of follow-up care is lacking. In this review, we discuss current billing practices of transplant programs for living kidney donor follow-up, and propose future directions for managing follow-up costs and supporting cost neutrality in donor care. Recent Findings Living donors may incur costs and financial risks in the donation process, including travel, lost time from work, and dependent care. In addition, adherence to the Organ Procurement and Transplantation Network (OPTN) mandate for US transplant programs to submit 6-, 12-, and 24-month postdonation follow-up data to the national registry may incur out-of-pocket medical costs for donors. Notably, the Centers for Medicare and Medicaid Services (CMS) has explicitly disallowed transplant programs to bill routine, mandated follow-up costs to the organ acquisition cost center or to the recipient’s Medicare insurance. We conducted a survey of transplant staff in the USA (distributed October 22, 2020–March 15, 2021), which identified that the mechanisms for recovering or covering the costs of mandated routine postdonation follow-up at responding programs commonly include billing recipients’ private insurance (40%), while 41% bill recipients’ Medicare insurance. Many programs reported utilizing institutional allowancing (up to 50%), and some programs billed the organ acquisition cost center (25%). A small percentage (11%) reported billing donors or donors’ insurance. Summary To maintain a high level of adherence to living donor follow-up without financially burdening donors, up-to-date resources are needed on handling routine donor follow-up costs in ways that are policy-compliant and effective for donors and programs. Development of a government-supported national living donor follow-up registry like the Living Donor Collective may provide solutions for aspects of postdonation follow-up, but requires transplant program commitment to register donors and donor candidates as well as donor engagement with follow-up outreach contacts after donation.

Abstract
BACKGROUND Living kidney donation is safe and effective, but disincentives to donation include risk of short- and long-term complications, which need to be addressed in order to ensure care of live kidney donors. METHODS From January 1, 2016 to December 31, 2019, 123 living kidney donors (LKDs) underwent LKD nephrectomy at Aarhus University Hospital, Aarhus, Denmark. Data from The Scandiatransplant registry and patient records were reviewed in order to identify short-term postoperative complications within 90 days after donation, as well as affiliation to the labor market and health data at follow-up. The Clavien-Dindo classification of surgical complications with modifications by Kocak et al was used to categorize minor and major complications. RESULTS There were available data for 119 of 123 LKDs. Of these, 25 (21%) developed minor complications and 4 (3%) developed major complications. Ninety LKDs (76%) had an uneventful course without any complications. The most common complications were pain and nausea that required additional medical treatment. Seventy-two of the 82 LKDs working before donation had returned to work within 3 months after donor nephrectomy. No one retired or became disabled as a result of being a live kidney donor. CONCLUSIONS Short-term follow up of the LKDs showed that most donors experienced an uneventful course and that the frequency of major complications was low. Donation did not seem to impact the ability to resume work. At the 90-day follow-up the majority of donors with both minor and major complications resumed work and reported full convalescence at the same level as donors without any complications. Nine of the LKDs (8%), all women, were out of work for >3 months with the main reason being fatigue.

Abstract
Organ shortage is a major survival issue for millions of people worldwide. Globally 1.2 million people die each year from kidney failure. In this paper, we critically examine and find lacking extant proposals for increasing organ supply, such as opting in and opt out for deceased donor organs, and parochial altruism and paired kidney exchange for live organs. We defend two ethical solutions to the problem of organ shortage. One is to make deceased donor organs automatically available for transplant without requiring consent from the donor or their relatives. The other is for society to buy nonvital organs in a strictly regulated market and provide them to people in need for free.

Abstract
Cardiovascular disease and mineral bone disorders are major contributors to morbidity and mortality among patients with chronic kidney disease and often persist after renal transplantation. Ongoing hormonal imbalances after kidney transplant (KT) are associated with loss of graft function and poor outcomes. Fibroblast growth factor 23 (FGF-23) and its co-receptor, α-Klotho, are key factors in the underlying mechanisms that integrate accelerated atherosclerosis, vascular calcification, mineral disorders, and osteodystrophy. On the other hand, kidney donation is also associated with endocrine and metabolic adaptations that include transient increases in circulating FGF-23 and decreases in α-Klotho levels. However, the long-term impact of these alterations and their clinical relevance have not yet been determined. This manuscript aims to review and summarize current data on the role of FGF-23 and α-Klotho in the endocrine response to KT and living kidney donation, and importantly, underscore specific areas of research that may enhance diagnostics and therapeutics in the growing population of KT recipients and kidney donors.

Abstract
Living kidney donation is associated with glomerular hyperfiltration, predisposing for the development of chronic kidney disease. The present meta-analysis aims to gather current evidence and clarify whether kidney donors are at increased risk of future pregnancy complications. Medline, Scopus, Web of Science, CENTRAL and Google Scholar were systematically searched from inception to August 29, 2021. Observational studies comparing the rates of adverse pregnancy outcomes among kidney donors and non-donors were selected. Random-effects models were fitted to provide meta-analysis estimates, while the quality of evidence was appraised with the Grading of Recommendations Assessment, Development and Evaluation approach. Five studies were included, comprising 430 donors and 23,540 non-donors. Living kidney donation was associated with significantly higher risk of preeclampsia (OR: 2.86, 95% CI: 1.62-5.05, moderate quality of evidence), gestational hypertension (OR: 2.53, 95% CI: 1.11-5.74, low quality of evidence) and preterm birth (OR: 1.32, 95% CI: 1.01-1.74, moderate quality of evidence). The anticipated absolute rates of preeclampsia, gestational hypertension and preterm birth were 7.4%, 5.4% and 8.3%, respectively. The risk of gestational diabetes, cesarean delivery, low birthweight and fetal death was similar between the two groups (low quality of evidence). In conclusion, women with history of kidney donation are at significantly increased risk of preeclampsia, gestational hypertension and preterm birth in subsequent pregnancies, although the absolute rate of complications remains below 10%. Future studies should confirm these effects and improve potential donor counseling by individualizing the risk of adverse perinatal outcomes.

Abstract
Objective: Living liver and kidney donor surgeries are major surgical procedures applied to healthy people with mortality and morbidity risks not providing any direct therapeutic advantage to the donor. In this study, we aimed to share our simultaneous and sequential living liver-kidney donor experience under literature review in this worldwide rare practice.
Material and Methods: Between January 2007 and February 2018, a total of 1109 living donor nephrectomies and 867 living liver donor hepatectomies were performed with no mortality to living-related donors. Eight donors who were simultaneous or sequential living liver-kidney donors in this time period were retrospectively reviewed and presented with their minimum 2- year follow-up.
Results: Of the 8 donors, 3 of them were simultaneous and 5 of them were sequential liver-kidney donation. All of them were close relatives. Mean age was 39 (26-61) years and mean BMI was 25.7 (17.7-40). In 3 donors, right lobe, in 4 donors, left lateral sector, and in 1 donor, left lobe hepatectomy were performed. Median hospital stay was 9 (7-13) days. Two donors experienced early and late postoperative complications (Grade 3b and Grade 1). No mortality and no other long-term complication occurred.
Conclusion: Expansion of the donor pool by utilizing grafts from living donors is a globally-accepted proposition since it provides safety and successful outcomes. Simultaneous or sequential liver and kidney donation from the same donor seems to be a reasonable option for combined liver-kidney transplant recipients in special circumstances with acceptable outcomes.

Transplant Rev (Orlando) 2021; 35:100638. [PMID: 34246111 DOI: 10.1016/j.trre.2021.100638] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2021] [Revised: 06/29/2021] [Accepted: 06/29/2021] [Indexed: 01/15/2023]
Abstract
INTRODUCTION Accurate estimations of potential organ donors (POTDs) are required to improve transplant systems. This systematic review analyses current studies on national estimations of potential donors for transplantation as well as the practical and policy implications of detected differences. METHOD A systematic review of literature published between 01.01.2010 and 01.04.2020 in PubMed was conducted. Data was extracted into a self-developed matrix, and further data retrieved on national population sizes, waiting lists and transplant activities. RESULTS Six studies were included. Investigated populations, underlying data collections and eligibility criteria for POTDs varied widely. Estimated POTDs per million population (p.m.p.) ranged from 25.8 to 333.6, conversion rates from 3.2% to 47.5% leading to 41.2 to 86.4 transplanted organs p.m.p.. Patients on the waiting lists varied from 66.7 to 338.9 p.m.p., defining gaps between organ supply and demand in countries. Not all studies adhered to the definitions and processes of the critical pathway for deceased donation which is the latest international consensus statement on deceased organ donation. CONCLUSION Differences in estimated POTDs and differences in supply and demand of donor organs between countries cannot be satisfactorily explained yet due to an obvious lack of evidence, consistent methodology, international consensus and robust underlying datasets. Future studies should be based on robust underlying data sets and aim for potential donor estimations that allow national comparisons due to the adherence to the international consensus on definitions, processes and methodology.

Abstract
BACKGROUND Living organ donation declined substantially in the United States during the COVID-19 pandemic due to concerns about donor and transplant candidate safety. COVID-19 vaccines might increase confidence in the safety of living organ donation during the pandemic. We assessed informational preferences and perspectives about COVID-19 vaccines among US living organ donors and prospective donors. METHODS We conducted a national survey study of organ donors and prospective donors on social media platforms between 12/28/2020-2/23/2021. Survey items included multiple choice, visual analog scale, and open-ended responses. We examined associations between information preferences, history of COVID-19 infection, influenza vaccination history and COVID-19 vaccine acceptance using multivariable logistic regression and performed a thematic analysis of open-ended responses. RESULTS Among 342 respondents from 47 US states and the District of Columbia, 35% were between 51-70 years old, 90% were non-Hispanic white, 87% were women; 82% were living donors (94% kidney) and 18% in evaluation to donate (75% kidney).The majority planned to or had received COVID-19 vaccination (76%), whereas 11% did not plan to be receive a vaccine, and 12% were unsure. Adjusting for demographics and donor characteristics, respondents who receive yearly influenza vaccinations had higher COVID-19 vaccine acceptance than those who do not (adjusted Odds Ratio [aOR] 5.06, 95% Confidence Interval [CI] 2.68-9.53). Compared to respondents who prioritized medical information sources (e.g., personal physicians and transplant providers), those who prioritized news and social media had lower COVID-19 vaccine acceptance (aOR 0.34, 95% CI 0.15-0.73). Low perceived personal benefit from vaccination and uncertainty about long-term safety were common themes among those declining COVID-19 vaccines. CONCLUSIONS Donor informational source preferences were strongly associated with the likelihood of accepting a COVID-19 vaccine. Vaccine guidance for organ donors who are unsure about COVID-19 vaccines could incorporate messaging about safety and benefits of vaccination for healthy people.

Abstract
Living kidney donors represent a unique population of patients. Potential donors are selected based on the belief that their preoperative fitness is likely to mitigate the risks of long- and short-term harm following uninephrectomy. Studies performed on postdonation outcomes have largely focused on mortality and the risk of end-stage renal failure, but have also investigated secondary outcomes such as cardiovascular morbidity and hypertension. It has been postulated that hypertension is a possible outcome of living kidney donation. A variety of studies have been conducted to investigate the prevalence, epidemiology, mechanisms, treatment strategies, and long-term ramifications of hypertension postdonation. These studies are heterogeneous in their population, design, methodology, and outcome measures and have presented contradicting outcomes. Additionally, the absence of a well-matched control group has made it challenging to interpret and generalise the reported findings. As such, it is not possible to definitively conclude that hypertension occurs at a higher rate among donors than the general population. This article will review the evidence of postdonation hypertension prevalence, mechanisms, treatment, and complications.

Abstract
BACKGROUND Worldwide, the supply of organs continues to be much less than the demand. Many studies identify poor knowledge and negative attitude about organ donation for this. The purpose of this study was to assess knowledge and attitude towards organ donation and associated factors among people who accompany patient during hospital visit at tertiary hospital in Ethiopia. METHODS A hospital-based cross-sectional study was conducted from March 1st to May 31, 2019, at a tertiary hospital and the only transplant center in Ethiopia. The patient companions were interviewed with structured questionnaires. Descriptive statistics were presented and factors associated with good knowledge and favorable attitude were assessed using Binary logistic regression. RESULTS A total of 414 patient companion participated in the study. The mean age of the respondents was 35±13years, and 252(60.9%) were males. Forty-four (10.6%) of the study participants had good knowledge about organ donation. Male gender was significantly associated with improved knowledge (AOR=2.127 95% CI: 1.036, 4.368). A favorable attitude towards donation was found in 219(52.9%) of the study participants. Participants who had completed secondary education were more likely to have unfavorable attitude towards organ donation (AOR =0.498, 95% CI: 0.290, 0.857). CONCLUSION Knowledge about organ donation was found to be poor, and attitudes towards organ donation were found to be unfavorable among patient companions at a major medical center in Ethiopia. Strategies focused on education of the general public and broad dissemination of information on the benefits of organ donation will be critical for improving the organ donor pool.

Abstract
BACKGROUND Routine placement of prophylactic drains after laparoscopic donor nephrectomy has been suggested and has become common practice in some centers. However, there is a lack of evidence proving the surgical benefits of routine drain placement in laparoscopic donor nephrectomy. Here, we assessed the effect of surgical drain placement on recovery, length of hospital stay, and complication rates of live kidney donors. MATERIAL AND METHODS This retrospective study included all live donor nephrectomies performed at a single institution from January 2010 to January 2017. Surgeries were performed by 2 surgeons; one routinely placed a closed suction drain after LDN whereas the other did not. Patients operated on by these 2 surgeons were enrolled in either the drain or no drain group. Demographic data, preoperative and postoperative creatinine levels, estimated blood loss (EBL), surgical time, surgical complications, and length of hospital stay were compared. RESULTS The study included 272 patients. Three were converted to open donor nephrectomy and were excluded (1.1%). Among the 269 patients, 156 (57.9%) had surgical drains and 113 (42.1%) did not. Mean surgical time, estimated blood loss, and duration of hospital stay did not significantly differ between groups. Postoperative complications were encountered in 17 of the patients, but the overall complication rate did not differ between patients with vs. those without surgical drains. CONCLUSIONS There was no significant difference between the drain and no drain groups in terms of length of hospital stay, complication rates, or postoperative creatinine levels. Thus, placement of a surgical drain in the setting of an LDN is not justified based on our single-center experience.

Abstract
Donors have a higher risk of developing chronic kidney disease than the general population. Some mechanisms mediated by pro-inflammatory cytokines and oxidative stress may be involved as risk factors. The objective of the study was to evaluate the behavior of pro-inflammatory cytokines and oxidative stress markers in living renal donors with a 6-month follow-up. A single prospective cohort was performed in 88 renal donors. At the end of the follow-up, the levels of lipoperoxides, 6.52 ± 1.12 mM, and 8-isoprostanes, 63.75 ± 13.28 pg/mL, were lower than before donation, 10.20 ± 3.95 mM (p < 0.001) and 67.54 ± 9.64 pg/mL (p = 0.026), respectively. Initial levels of nitric oxide (NO), 356.09 ± 59.38 μM increased at the end of the follow-up, 467.08 ± 38.74 μM (p < 0.001). It was observed in the final determination of donors decreased activity of antioxidant enzymes superoxide dismutase (SOD), 0.74 ± 0.57 U/L and glutathione peroxidase (GPx), 556.41 ± 80.37 nmol, in comparison with the levels obtained in the initial determination, 1.05 ± 0.57 U/L (p < 0.001) and 827.93 ± 162.78 nmol (p < 0.001), respectively. The pro-inflammatory cytokines, Tumor necrosis factor alpha and interleukin-6 showed no differences at 6 months after donation. The enzyme oxoguanine glycosylase (hOGG1) responsible for repairing oxidative damage to DNA, showed a decrease in its concentration at the end of the study in donor men, 0.40 ± 0.21 ng/mL compared to the initial levels, 0.55 ± 0.32 ng/mL (p = 0.025). The marker, 8-hydroxy-2-deoxyguanosine (8-OHdG) exhibited an increase in donor men at the final determination 2.28 ± 1.99 ng/mL, compared to the concentration before donation, 1.72 ± 1.96 ng/mL (p < 0.001). We found significant changes in the markers of the oxidative state with increased NO and 8-OHdG, as well as a significant decrease in the antioxidant defenses SOD, GPx, and in the DNA repair enzyme in living renal donors after 6 months of follow-up.

Abstract
α-Klotho is a known anti-aging protein that exerts diverse physiological effects, including phosphate homeostasis. Klotho expression occurs predominantly in the kidney and is significantly decreased in patients with chronic kidney disease. However, changes in serum klotho levels and impacts of klotho on outcomes among kidney transplant (KTx) recipients and kidney donors remain unclear. A literature search was conducted using MEDLINE, EMBASE, and Cochrane Database from inception through October 2019 to identify studies evaluating serum klotho levels and impacts of klotho on outcomes among KTx recipients and kidney donors. Study results were pooled and analyzed utilizing a random-effects model. Ten cohort studies with a total of 431 KTx recipients and 5 cohort studies with a total of 108 living kidney donors and were identified. After KTx, recipients had a significant increase in serum klotho levels (at 4 to 13 months post-KTx) with a mean difference (MD) of 243.11 pg/mL (three studies; 95% CI 67.41 to 418.81 pg/mL). Although KTx recipients had a lower serum klotho level with a MD of = -234.50 pg/mL (five studies; 95% CI -444.84 to -24.16 pg/mL) compared to healthy unmatched volunteers, one study demonstrated comparable klotho levels between KTx recipients and eGFR-matched controls. Among kidney donors, there was a significant decrease in serum klotho levels post-nephrectomy (day 3 to day 5) with a mean difference (MD) of -232.24 pg/mL (three studies; 95% CI -299.41 to -165.07 pg/mL). At one year following kidney donation, serum klotho levels remained lower than baseline before nephrectomy with a MD of = -110.80 pg/mL (two studies; 95% CI 166.35 to 55.24 pg/mL). Compared to healthy volunteers, living kidney donors had lower serum klotho levels with a MD of = -92.41 pg/mL (two studies; 95% CI -180.53 to -4.29 pg/mL). There is a significant reduction in serum klotho levels after living kidney donation and an increase in serum klotho levels after KTx. Future prospective studies are needed to assess the impact of changes in klotho on clinical outcomes in KTx recipients and living kidney donors.

Abstract
Living kidney donation is safe and established but can lead to short- and long-term complications. Hyponatremia is the most common disorder of body fluid and electrolyte balance in clinical practice, associated with increased morbidity, mortality, and the length of hospital stay. A correct diagnosis of the etiology of hyponatremia is critical, both to determine correct management and prognosis. Here, we present a case of a severe hyponatremia following left- sided donor nephrectomy with a physical examination suggestive of mild hypovolemia. Laboratory tests revealed high urine osmolality and sodium concentration mimicking syndrome of inappropriate antidiuretic hormone secretion (SIADH), in the setting of abnormally blunted response to Synacthen. The patient responded well to hydrocortisone replacement. Differentiating between primary adrenal insufficiency and SIADH as a cause of severe hyponatremia was the key to successfully treating this patient. Hyponatremia following donor nephrectomy is unusual and could be explained in this case by hypocortisolism.

Blood Pressure and Living Kidney Donors: A Clinical Perspective. Transplant Direct 2019; 5:e488.

Abstract
Elevated blood pressure (BP), or “hypertension,” has been one of the main exclusion criteria for living kidney donation, as it is a risk factor for renal and cardiovascular disease. The effect of elevated BP in living kidney donors is not well studied or understood. The most current living kidney donation guidelines state that donors with a BP >140/90 mm Hg with 1–2 antihypertensive medications or evidence of end-organ damage should be excluded from living kidney donation. Yet, the definitions of “hypertension” have changed with the release of the American Heart Association (AHA)/American College of Cardiology (ACC) clinical practice guidelines suggesting that 120–129 mm Hg is elevated BP and Stage 1 hypertension is 130 mm Hg. However, the kidney function (in terms of estimated GFR) of “hypertensive” living kidney donors does not fare significantly worse postdonation compared with that of “normotensive” donors. In addition, even though living kidney donation itself is not considered to be a risk factor for developing hypertension, there exist certain risk factors (African American or Hispanic descent, obesity, age) that may increase the risk of living kidney donors developing elevated BP postdonation. The choice of BP targets and medications needs to be carefully individualized. In general, a BP <130/80 mm Hg is needed, along with lifestyle modifications.

Abstract
BACKGROUND While living kidney donation is considered safe in healthy individuals, perioperative complications can occur due to several factors. OBJECTIVE We explored associations between the incidence of perioperative complications and donor characteristics, surgical technique, and surgeon's experience in a large contemporary cohort of living kidney donors. DESIGN Living kidney donors enrolled prospectively in a multicenter cohort study with some data collected retrospectively after enrollment was complete (eg, surgeon characteristics). SETTING Living kidney donor centers in Canada (n = 12) and Australia (n = 5). PATIENTS Living kidney donors who donated between 2004 and 2014 and the surgeons who performed the living kidney donor nephrectomies. MEASUREMENTS Operative and hospital discharge medical notes were collected prospectively, with data on perioperative (intraoperative and postoperative) information abstracted from notes after enrollment was complete. Complications were graded using the Clavien-Dindo system and further classified into minor and major. In 2016, surgeons who performed the nephrectomies were invited to fill an online survey on their training and experience. METHODS Multivariable logistic regression models with generalized estimating equations were used to compare perioperative complication rates between different groups of donors. The effect of surgeon characteristics on the complication rate was explored using a similar approach. Poisson regression was used to test rates of overall perioperative complications between high- and low-volume centers. RESULTS Of the 1421 living kidney donor candidates, 1042 individuals proceeded with donation, where 134 (13% [95% confidence interval (CI): 11%-15%]) experienced 142 perioperative complications (55 intraoperative; 87 postoperative). The most common intraoperative complication was organ injury and the most common postoperative complication was ileus. No donors died in the perioperative period. Most complications were minor (90% of 142 complications [95% CI: 86%-96%]); however, 12 donors (1% of 1042 [95% CI: 1%-2%]) experienced a major complication. No statistically significant differences were observed between donor groups and the rate of complications. A total of 43 of 48 eligible surgeons (90%) completed the online survey. Perioperative complication rates did not vary significantly by surgeon characteristics or by high- versus low-volume centers. LIMITATIONS Operative and discharge reporting is not standardized and varies among surgeons. It is possible that some complications were missed. The online survey for surgeons was completed retrospectively, was based on self-report, and has not been validated. We had adequate statistical power only to detect large effects for factors associated with a higher risk of perioperative complications. CONCLUSIONS This study confirms the safety of living kidney donation as evidenced by the low rate of major perioperative complications. We did not identify any donor or surgeon characteristics associated with a higher risk of perioperative complications.

Abstract
Kidney donors face a small but definite risk of end-stage renal disease 15 to 30 years postdonation. The development of proteinuria, hypertension with gradual decrease in kidney function in the donor after surgical resection of 1 kidney, has been attributed to hyperfiltration. Genetic variations, physiological adaptations, and comorbidities exacerbate the hyperfiltration-induced loss of kidney function in the years after donation. A focus on glomerular hemodynamics and capillary pressure has led to the development of drugs that target the renin-angiotensin-aldosterone system (RAAS), but these agents yield mixed results in transplant recipients and donors. Recent work on glomerular biomechanical forces highlights the differential effects of tensile stress and fluid flow shear stress (FFSS) from hyperfiltration. Capillary wall stretch due to glomerular capillary pressure increases tensile stress on podocyte foot processes that cover the capillary. In parallel, increased flow of the ultrafiltrate due to single-nephron glomerular filtration rate elevates FFSS on the podocyte cell body. Although tensile stress invokes the RAAS, FFSS predominantly activates the cyclooxygenase 2-prostaglandin E2-EP2 receptor axis. Distinguishing these 2 mechanisms is critical, as current therapeutic approaches focus on the RAAS system. A better understanding of the biomechanical forces can lead to novel therapeutic agents to target FFSS through the cyclooxygenase 2-prostaglandin E2-EP2 receptor axis in hyperfiltration-mediated injury. We present an overview of several aspects of the risk to transplant donors and discuss the relevance of FFSS in podocyte injury, loss of glomerular barrier function leading to albuminuria and gradual loss of renal function, and potential therapeutic strategies to mitigate hyperfiltration-mediated injury to the remaining kidney.

Abstract
In the past decade, there have been increasing efforts to better define and quantify the short- and long-term risks of living kidney donation. Recent studies have expanded upon the previous literature by focusing on outcomes that are important to potential and previous donors, applying unique databases and/or registries to follow large cohorts of donors for longer periods of time, and comparing outcomes with healthy nondonor controls to estimate attributable risks of donation. Leading outcomes important to living kidney donors include kidney health, surgical risks, and psychosocial effects of donation. Recent data support that living donors may experience a small increased risk of severe CKD and ESKD compared with healthy nondonors. For most donors, the 15-year risk of kidney failure is <1%, but for certain populations, such as young, black men, this risk may be higher. New risk prediction tools that combine the effects of demographic and health factors, and innovations in genetic risk markers are improving kidney risk stratification. Minor perioperative complications occur in 10%-20% of donor nephrectomy cases, but major complications occur in <3%, and the risk of perioperative death is <0.03%. Generally, living kidney donors have similar or improved psychosocial outcomes, such as quality of life, after donation compared with before donation and compared with nondonors. Although the donation process should be financially neutral, living kidney donors may experience out-of-pocket expenses and lost wages that may or may not be completely covered through regional or national reimbursement programs, and may face difficulties arranging subsequent life and health insurance. Living kidney donors should be fully informed of the perioperative and long-term risks before making their decision to donate. Follow-up care allows for preventative care measures to mitigate risk and ongoing surveillance and reporting of donor outcomes to inform prior and future living kidney donors.

Abstract
Prospective living kidney donors need meticulous evaluation prior to kidney donation. Ambulatory blood pressure monitoring (ABPM) is considered the reference standard for diagnosing hypertension. With no prior study available in India in this context, we undertook this study to evaluate the utility of ABPM in kidney donors and effect of donor nephrectomy on renal function. This was a prospective observational study involving healthy prospective kidney donors between 18 and 70 years with normal office blood pressure measurements (OBPM). Detailed clinical and biochemical parameters were recorded. OBPM and 24-hour ABPM was done preoperatively and 3 months following donor nephrectomy. There were 51 donors with a mean age of 46.1 ± 11.3 years, of which 40 (78.4%) were females. Preoperatively, three (5.8%) donors were hypertensive on ABPM but normal on OBPM (P = 0.08). Three months post nephrectomy, hypertension was present in seven (13.7%) donors by ABPM, while only two (3.9%) donors were diagnosed as hypertensive by OBPM (P = 0.02). Median pre-nephrectomy proteinuria was 70 mg (10 mg-180 mg) with a mean estimated glomerular filtration rate (eGFR) using the Modification of Diet in Renal Disease (MDRD) formula of 86.86 ± 19.1 ml/min. Six donors developed >300 mg/day proteinuria, and 17 (33.3%) had a 24-hour urinary protein excretion greater than 150 mg/day. Mean serum creatinine (0.79 ± 0.11 vs 1.03 ± 0.16 mg/dl) significantly increased post donation, more so in donors >55 years of age (1.14 ± 0.25 mg/dl). Our study shows that in transplant donors, ABPM is better for diagnosing hypertension, which otherwise remains masked in 10% of the donors on routine OBPM. Significance of post-nephrectomy hypertension and increasing proteinuria needs further evaluation.

Abstract
BACKGROUND The possibility of an increased risk of end-stage renal disease is a major concern associated with living kidney donation. Therefore, monitoring of residual kidney function becomes most essential. METHODS A data analysis of 156 living kidney donors (LKDs) was conducted. The efficacy of the long-term care system with regard to monitoring residual kidney function was evaluated. RESULTS The analyzed group consisted of 102 (65.4%) women. The mean follow-up period was 5.44 years. The rise in value of mean serum creatinine concentration after donation was observed, but it was within the range of normal during the observation period. Despite its initial decline after nephrectomy, mean glomerular filtration rate (GFR) remained >60 mL/min/1.73 m2. A MDRD (Modification of Diet in Renal Disease) GFR in the range of 45-60 mL/min/1.73 m2 was observed in 53 donors (33.97%). It was found to be <45.0 mL/min/1.73 m2 in 15 cases (9.6%). No patient developed end-stage renal disease. Only 25.0% of those analyzed had their CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) GFR estimated on 45-60 mL/min/1.73 m2 and 4.49% were found to have levels of <45 mL/min/1.73 m2 (down to 33.7 mL/min/1.73 m2). Mean postdonation CKD-EPI GFR was estimated at 69.99% of its predonation value. CONCLUSION A reliable qualification process could minimize the probability of kidney donation by someone with an increased risk of chronic kidney failure. The CKD-EPI formula seems to be more precise than the MDRD for estimatation of LKDs' GFR, as their loss of GFR is a result of nephrectomy and not kidney or systemic disease. Using the MDRD formula may lead to inappropriate diagnosis of CKD in some cases.

Abstract
Organ transplantation is a new issue in medical science. It is an important achievement and a sign of the progression and ability of medical centers around the world. Governments, populations, the medical community and people involved in culture, art, and media all have a decisive role in the culture of organ donation, which is the only way to guarantee that the healthy organs of a brain-dead person can continue to work and save the lives of people in need of organ transplantation. The brain death phenomenon and its possible application in organ transplantation, while offering new hope for the salvation of a number of patients, has led to many ethical, cultural, and legal issues. Ethical issues in organ transplantation are very complicated due to many social factors such as religion, culture, and traditions of the affected communities. The ethical and legal points of removing organs from the body of a living or cadaveric source, the definition of brain death, the moral and legal conditions of the donor and the recipient, and the financial relationship between them and many others, are all critical issues in organ transplantation. While there may be no available explicit solution to these issues, they should be rigorously considered by the experts. Efforts to systematically eliminate barriers and solve problems in organ transplantation, can not only reduce the costs of maintaining brain-dead patients and encourage patients that need organ transplantation but can also prevent immoral and illegal activities. In this paper, we have reviewed the most important and current challenges in organ transplantation with a view to the ethical considerations, and we have suggested some strategies to extend it in Iran.

Abstract
OBJECTIVE Malignancy following renal transplantation remains inconsistent with the reported safety of kidney donation during the long-term follow-up. METHODS We conducted searches of the published literature which included healthy participants, recipients, living kidney donors (LKDs), and the availability of outcome data for malignancy. Eight from 938 potentially relevant studies were analyzed by means of fixed-effects model or random-effects model, as appropriately. RESULTS In 48,950 participants, the follow-up range was 18 months to 20 years, and the mean age of the subjects was approximately 41 years. The incidence rate with 95% confidence interval (CI) for malignancy after kidney transplantation was 0.03 (0.01-0.05) in recipients and 0.03 (0.1-0.07) in LKDs, giving a pooled incidence rate of 0.03 (95% CI 0.02-0.04). LKDs contrasted nondonors by the overall odds ratio and 95% CI for total cancer of 2.80 (2.69-2.92). CONCLUSIONS Kidney transplantation was associated with an increased risk of cancer during a long-term follow-up. Long-term risk for cancer in LKDs and kidney recipients should be monitored.

Abstract
The shortage of suitable organs is the biggest obstacle for transplants. At present, most organs for transplant in the United States are from donation after neurologic determination of death (brain death). Potential organs for transplant need to maintain their viability during a series of insults, including the original disease, physiologic derangements during the dying process, ischemia, and reperfusion. Proper donor management before, during, and after procurement has potential to increase the number and quality of organs from donors. Anesthesiologists need to understand the physiologic derangements associated with brain death and the updated donor management during the periprocurement period.

Abstract
PURPOSE The goal of this study was to externally validate the recently proposed prognostic model for the prediction of estimated glomerular filtration rate (eGFR) < 60 ml/min/1.73 m2 1 year after living donor nephrectomy. METHODS 130 living kidney donors (median age at donation 52.3 years, range 24.7-75.6 years) were investigated before and after donation between March 2000 and April 2016. Preoperative eGFR values varied between 61.7 and 148.4 ml/min (mean: 89, median: 88). Observed eGFR 1 year after transplantation (±45 days) ranged between 36.3 and 97.1 ml/min (mean: 55, median: 53). 70.8% of donors displayed eGFR values < 60 ml/min 1 year after donation. Predicted eGFR 1 year after donation was determined using the prognostic model proposed by Benoit et al. (Int Urol Nephrol 49(5):793-801. doi: 10.1007/s11255-017-1559-1 , 2017): postoperative eGFR ml/min/1.73 m2 = 31.71 + (0.521 × eGFR in ml/min prior to donation -0.314 × Age in years at donation). Pearson correlation and receiver operating characteristics curve (ROC-curve) were used to assess external validity of the proposed prognostic model to predict postoperative eGFR in ml/min and eGFR < 60 ml/min. RESULTS The correlation between predicted and observed eGFR 1 year after donation was significant (p < 0.001; R 2 = 0.594). The area under the ROC-curve (AUROC) demonstrated a high sensitivity and specificity for predicted eGFR values < 60 ml/min (AUROC = 0.866). CONCLUSIONS The proposed prognostic model for the prediction of postoperative eGFR was successfully validated in our cohort. We therefore consider the model as generally applicable.

Abstract
Kidney Disease: Improving Global Outcomes (KDIGO) engaged an evidence review team and convened a work group to produce a guideline to evaluate and manage candidates for living kidney donation. The evidence for most guideline recommendations is sparse and many "ungraded" expert consensus recommendations were made to guide the donor candidate evaluation and care before, during, and after donation. The guideline advocates for replacing decisions based on assessments of single risk factors in isolation with a comprehensive approach to risk assessment using the best available evidence. The approach to simultaneous consideration of each candidate's profile of demographic and health characteristics advances a new framework for assessing donor candidate risk and for defensible shared decision making.

Abstract
BACKGROUND Familial Mediterranean fever (FMF) is an autosomal-recessive autoinflammatory disorder manifested severely by systemic amyloidosis. It has been hypothesized that heterozygous carriers may also have susceptibility to certain symptoms or even diseases. Because the living kidney donors of patients with FMF are generally relatives of the kidney recipients, there is a high possibility that the donors will have a heterozygous mutation of the FMF gene. The goal of this study was to investigate the long-term kidney function of donors who are carriers of the Mediterranean fever (MEFV) gene. METHODS The medium- to long-term outcomes of 12 asymptomatic donors were compared with MEFV gene carriers and 24 non-FMF recipients' donors. RESULTS Heterozygous carriers and the control group were similar with respect to age, sex, and follow-up period. The preoperative estimated glomerular filtration rate and 24-hour urine proteinuria levels were similar in the MEFV carrier and control groups. Four years after the donation, both groups had similar estimated glomerular filtration rates, but the change in 24-hour urine protein was statistically higher in the MEFV carrier group, and no significant change was observed in the control group (P = .004). At the end of the follow-up period, neither overt proteinuria nor kidney failure was seen in either group. CONCLUSIONS This study showed that the medium- to long-term results of the kidney donors who are carriers of the MEFV gene seem to be safe. However, there was more of a tendency for an increase in proteinuria in the MEFV gene carriers compared with control subjects, which necessitated further long-term care for these donors.

Abstract
Communicating the current knowledge of medical outcomes after live kidney donation necessary to support donor candidates in well informed decision-making requires grounding in perspectives of comparison. Baseline risk (without donating), risk attributable to donation, and absolute risk (after donating) need to be considered. Severe perioperative complications and death are rare, but vary by demographic, clinical, and procedure factors. Innovative capture of "healthy" controls designed to simulate donor selection processes has identified higher risk of ESRD attributable to donation in two studies; importantly, however, the absolute 15-year ESRD incidence in donors remains very low (0.3%). In the first decade after donation, the risk of all-cause mortality and cardiovascular events is no higher than in healthy nondonors. Pregnancies in donors may incur attributable risk of gestational hypertension or preeclampsia (11% versus 5% incidence in one study). A modest rise in uric acid levels beginning early after donation, and a small (1.4%) increase in the 8-year incidence of gout, have also been reported in comparisons to healthy nondonors. As in the general population, postdonation outcomes vary by race, sex, and age. Efforts to improve the counseling and selection of living donors should focus on developing tools for tailored risk prediction according to donor characteristics, and ideally, compared with similar healthy nondonors.

Abstract
Some transplant programs consider the lack of health insurance as a contraindication to living kidney donation. Still, prior studies have shown that many adults are uninsured at time of donation. We extend the study of donor health insurance status over a longer time period and examine associations between insurance status and relevant sociodemographic and health characteristics. We queried the United Network for Organ Sharing/Organ Procurement and Transplantation Network registry for all living kidney donors (LKDs) between July 2004 and July 2015. Of the 53 724 LKDs with known health insurance status, 8306 (16%) were uninsured at the time of donation. Younger (18 to 34 years old), male, minority, unemployed, less educated, unmarried LKDs and those who were smokers and normotensive were more likely to not have health insurance at the time of donation. Compared to those with no health risk factors (i.e. obesity, smoking, hypertension, estimated glomerular filtration rate <60, proteinuria) (14%), LKDs with 1 (18%) or ≥2 (21%) health risk factors at the time of donation were more likely to be uninsured (p < 0.0001). Among those with ≥2 health risk factors, blacks (28%) and Hispanics (27%) had higher likelihood of being uninsured compared to whites (19%; p < 0.001). Study findings underscore the importance of providing health insurance benefits to all previous and future LKDs.

Abstract
INTRODUCTION The aim of the present study was to compare long-term donor outcomes after open and laparoscopic living donor nephrectomy. The focus was on pregnancy rates, hypertension and quality of life parameters. MATERIALS AND METHODS Data were retrospectively collected using our institution's electronic database and a structured questionnaire. The study included 30 donors after open donor nephrectomy (ODN) and 131 donors after laparoscopic donor nephrectomy (LDN). RESULTS Demographic data did not differ between groups. When asked for their preference, significantly more donors in the LDN group would choose the same surgical approach again. The overall frequency of postoperative complications was significantly lower in the LDN group. The incidence of grade III complications was 2% after LDN and 10% after ODN (p = 0.79). Only 2 out of 15 female donors aged between 18 and 45 years delivered a healthy child after DN. On interview, only 4 out of 15 female donors declared the desire to have children after DN. CONCLUSIONS From the donor perspective, long-term outcomes after LDN are more favorable than after ODN. To ensure favorable functional outcomes, strict preoperative donor selection and diligent long-term donor follow-up are required.

Abstract
PURPOSE Outcome after living donor kidney transplantation is highly relevant, since recipient and donor were exposed to notable harm. Reliable identification of risk factors is necessary. METHODS Three hundred sixty-six living donor kidney transplants were included in this observational retrospective study. Relevant risk factors for renal impairment 1 year after transplantation and delayed graft function were identified with univariable and multivariable binary logistic regression and ordinal regression analysis. RESULTS Eighty-four patients (26.6 %) suffered from renal impairment KDIGO stage ≥4 1 year post-transplant; median estimated glomerular filtration rate was 35.3 ml/min. In multivariable ordinal regression, male recipient sex (p < 0.001), recipient body mass index (p = 0.006), donor age (p = 0.002) and high percentages of panel reactive antibodies (p = 0.021) were revealed as independent risk factors for higher KDIGO stages. After adjustment for post-transplant data, recipient male sex (p < 0.001), donor age (p = 0.026) and decreased early renal function at the first post-transplant outpatient visit (p < 0.001) were identified as independent risk factors. Delayed graft function was independently associated with long stay on the waiting list (p = 0.011), high donor body mass index (p = 0.043), prolonged warm ischemic time (p = 0.016) and the presence of preformed donor-specific antibodies (p = 0.043). CONCLUSIONS Broadening the donor pool with non-blood related donors seems to be legitimate, although with respect to careful medical selection, since donor age in combination with male recipient sex were shown to be risk factors for decreased graft function. Warm ischemic time and waiting time need to be kept as short as possible to avoid delayed graft function. Transplantation across HLA and ABO borders did not affect outcome significantly.

Abstract
Given the increased burden of end-stage renal disease (ESRD), renal outcomes of kidney donation by living donors are of particular interest. PubMed, ProQuest, MEDLINE, EMBASE, Chinese national knowledge infrastructure, and Wanfang databases were searched for clinical outcomes of living kidney donors (LKDs) including renal death, ESRD, proteinuria/albuminuria, and renal function after donation. We included 62 studies from 19 countries involving 114,783 kidney donors and nondonors to evaluate the renal consequences less than 6 months, 6 months to 5 years, 5 to 10 years, and 10 years onward after donation. The pooled data showed that uninephrectomy significantly decreased glomerular filtration rate and creatinine clearance rate in parallel with increased serum creatinine concentration (all P < 0.05). The drastic changes in renal function occurred within 6 months rather than 5 to 10 years after donation. Ten years and onward, rate of proteinuria/albuminuria increased gradually: microalbuminuria from 5.3% to 20.9%, proteinuria from 4.7% to 18.9%, and overt proteinuria from 2.4% to 5.7% (all P < 0.05). Prevalence of ESRD was 1.1%. All-cause mortality was 3.8% and all the renal deaths on average occurred 10 years postnephrectomy. LKDs might have aggravated glomerular filtration and creatinine clearance within 6 months after donation. Five years and onward, albuminuria, proteinuria, ESRD, and death might be the major concerns of LKDs. Long-term studies may clarify the survival time after donation.

Abstract
We integrated the US transplant registry with administrative records from an academic hospital consortium (97 centers, 2008-2012) to identify predonation comorbidity and perioperative complications captured in diagnostic, procedure, and registry sources. Correlates (adjusted odds ratio, aOR) of perioperative complications were examined with multivariate logistic regression. Among 14 964 living kidney donors, 11.6% were African American. Nephrectomies were predominantly laparoscopic (93.8%); 2.4% were robotic and 3.7% were planned open procedures. Overall, 16.8% of donors experienced a perioperative complication, most commonly gastrointestinal (4.4%), bleeding (3.0%), respiratory (2.5%), surgical/anesthesia-related injuries (2.4%), and "other" complications (6.6%). Major Clavien Classification of Surgical Complications grade IV or higher affected 2.5% of donors. After adjustment for demographic, clinical (including comorbidities), procedure, and center factors, African Americans had increased risk of any complication (aOR 1.26, p = 0.001) and of Clavien grade II or higher (aOR 1.39, p = 0.0002), grade III or higher (aOR 1.56, p < 0.0001), and grade IV or higher (aOR 1.56, p = 0.004) events. Other significant correlates of Clavien grade IV or higher events included obesity (aOR 1.55, p = 0.0005), predonation hematologic (aOR 2.78, p = 0.0002) and psychiatric (aOR 1.45, p = 0.04) conditions, and robotic nephrectomy (aOR 2.07, p = 0.002), while annual center volume >50 (aOR 0.55, p < 0.0001) was associated with lower risk. Complications after live donor nephrectomy vary with baseline demographic, clinical, procedure, and center factors, but the most serious complications are infrequent. Future work should examine underlying mechanisms and approaches to minimizing the risk of perioperative complications in all donors.

Abstract
Kidney transplantation significantly improves patient survival, and is the most cost effective renal replacement option compared with dialysis therapy. Living kidney donors provide a valuable societal gift, but face many formidable disincentive barriers that include not only short- and long-term health risks, but also concerns regarding financial expenditures and health insurance. Other than governmental coverage for their medical evaluation and surgical expenses, donors are often asked to personally bear a significant financial responsibility due to lost work wages and travel expenses. In order to alleviate this economic burden for donors, we advocate for the consideration of tax credits, lifelong health insurance coverage, and an outcomes registry as societal reciprocity to reward their altruistic act of kidney donation.

Abstract
Living donor hepatectomy (LDH) is high risk to a healthy donor and remains controversial. Living donor nephrectomy (LDN), conversely, is a common practice. The objective is to examine the outcomes of LDH and compare this risk profile to LDN. The Nationwide Inpatient Sample was queried for hepatectomies and nephrectomies from 1998 to 2011. LDH or LDN were identified by donor ICD-9 codes. Outcomes included in-hospital mortality and complications. Bivariate analysis compared nondonor hepatectomy or nondonor nephrectomy (NDN). Multivariate analyses adjusted for baseline organ disease, malignancy, or benign lesions. There were 430 LDH and 9211 nondonor hepatectomy. In-hospital mortality was 0 and 6 per cent, respectively ( P < 0.001); complications 4 and 33 per cent ( P < 0.001). LDH had fewer complications [odds ratio (OR) 0.15 (0.08–0.26)]. There were 15,631 LDN and 117,966 NDN. Mortality rates were 0.8 per cent LDN and 1.8 per cent NDN ( P < 0.001). Complications were 1 and 21 per cent ( P < 0.001). LDN had fewer complications [OR 0.06 (0.05–0.08)] and better survival [OR 0.32 (0.18–0.58)]. Complication rates were higher in LDH than LDN (4% vs 1%, P < 0.001), but survival was similar (0% vs 0.8% mortality, P = 0.06). In conclusion, morbidity and mortality rates of LDH are significantly lower than hepatectomy for other disease. This study suggests that the risk profile of LDH is comparable with the widely accepted LDN.

Abstract
Follow-up care for living kidney donors is an important responsibility of the transplant community. Prior reports indicate incomplete donor follow-up information, which may reflect both donor and transplant center factors. New UNOS regulations require reporting of donor follow-up information by centers for 2 years. We utilized national SRTR data to evaluate donor and center-level factors associated with completed follow-up for donors 2008-2012 (n = 30 026) using multivariable hierarchical logistic models. We compared center follow-up compliance based on current UNOS standards using adjusted and unadjusted models. Complete follow-up at 6, 12, and 24 months was 67%, 60%, and 50% for clinical and 51%, 40%, and 30% for laboratory data, respectively, but have improved over time. Donor risk factors for missing laboratory data included younger age 18-34 (adjusted odds ratio [AOR] = 2.03, 1.58-2.60), black race (AOR = 1.17, 1.05-1.30), lack of insurance (AOR = 1.25, 1.15-1.36), lower educational attainment (AOR = 1.19, 1.06-1.34), >500 miles to center (AOR = 1.78, 1.60-1.98), and centers performing >40 living donor transplants/year (AOR = 2.20, 1.21-3.98). Risk-adjustment moderately shifted classification of center compliance with UNOS standards. There is substantial missing donor follow-up with marked variation by donor characteristics and centers. Although follow-up has improved over time, targeted efforts are needed for donors with selected characteristics and at centers with higher living donor volume. Adding adjustment for donor factors to policies regulating follow-up may function to provide more balanced evaluation of center efforts.

Abstract
Few studies have examined HRQOL in pediatric Tx recipients' parents. This study investigated HRQOL in these parents and relationships between HRQOL and perceived burden of nurturing, family functioning, and social support. Self-report anonymous questionnaires and a survey of medical records were completed between September and December 2013. The SF-36v2, which evaluates physical, psychological, and social health, was used to measure HRQOL. While values for physical and psychological health were higher than standard values (Cohen's d = 0.34 and 0.17, respectively), social health scores were lower (d = 0.21). "Parental consultation unrelated to donation" (standardized partial regression coefficient: β = -0.52) was associated with physical health. "Family functioning" and "Commuting time between home and primary follow-up hospital" (β = 0.57 and -0.31) were related to psychological health. "Total score for perceived burden of nurturing" (β = -0.31) was related to social health. Regarding parental HRQOL, while physical and psychological health was favorable, social health was impaired. In clinical practice, interventions targeting parents' physical conditions and facilitation of community and family understanding and support to share recipients' nurturing are important in improving parental HRQOL.

Abstract
Live donor kidney transplantation is the best treatment option for most patients with late-stage chronic kidney disease; however, the rate of living kidney donation has declined in the United States. A consensus conference was held June 5-6, 2014 to identify best practices and knowledge gaps pertaining to live donor kidney transplantation and living kidney donation. Transplant professionals, patients, and other key stakeholders discussed processes for educating transplant candidates and potential living donors about living kidney donation; efficiencies in the living donor evaluation process; disparities in living donation; and financial and systemic barriers to living donation. We summarize the consensus recommendations for best practices in these educational and clinical domains, future research priorities, and possible public policy initiatives to remove barriers to living kidney donation.
