Abstract
The aim of this analysis was to explore mortality outcomes for kidney transplant candidates receiving older living donor kidneys (age ≥60 years) versus younger deceased donors or remaining on dialysis. From 2000 to 2019, all patients on dialysis listed for their first kidney-alone transplant were included in a retrospective cohort analysis of UK transplant registry data. The primary outcome was all-cause mortality, with survival analysis conducted by intention-to-treat principle. Time-to-death from listing was modelled using nonproportional hazard Cox regression models with transplantation handled as a time-dependent covariate. A total of 32,978 waitlisted kidney failure patients formed the primary study cohort, of whom 18,796 (58.5%) received a kidney transplant (1,557 older living donor kidneys and 18,062 standard criteria donor kidneys). Older living donor kidney transplantation constituted only 17.0% of all living donor kidney transplant activity (overall cohort; n = 9,140). Recipients of older living donor kidneys had reduced all-cause mortality compared to receiving SCD kidneys (HR 0.904, 95% CI 0.845-0.967, p = 0.003) and much lower all-cause mortality versus remaining on the waiting list (HR 0.160, 95% CI 0.149-0.172, p < 0.001). Older living kidney donors should be actively explored to expand the living donor kidney pool and are an excellent treatment option for waitlisted kidney transplant candidates.

Abstract
BACKGROUND Although testosterone has a pivotal role in bone health, its correlation with bone mineral density (BMD) is understudied in kidney transplant recipients who are at high risk of osteoporosis. This study aimed to elucidate if there is any correlation between serum free testosterone and BMD in this population. PATIENTS AND METHODS Sixty male kidney transplant recipients were enrolled in this cross-sectional study, and they were subjected to history taking, clinical examination, and laboratory investigations (including total and free testosterone). BMD was assessed in three regions (forearm, hip, and lumbar spine) using DEXA scan. RESULTS The mean age of the included patients was 45.55 ± 13.58 years. Serum total and free testosterone had mean values of 5.17 ± 1.4 ng/ml and 95.46 ± 28.24 pg/ml, respectively, with all levels within the normal range. DEXA scan detected osteoporosis and osteopenia in 9 (15%) and 30 (50%) patients in the lumbar region, 3 (5%) and 36 (60%) in the hip region, as well as 21 (35%) and 33 (55%) in the forearm region, respectively. BMD of the lumbar region had a significant positive correlation with free testosterone, phosphorus, and eGFR, while it had a significant negative correlation with platelets and patient age. BMD of the hip region was positively correlated with serum phosphorus, parathyroid hormone, and duration since the transplant, whereas it was negatively correlated with platelets and total testosterone level. BMD of the forearm had a significant positive correlation with eGFR, whereas it had a significant negative correlation with age and duration since transplantation. In addition, forearm BMD was significantly lower in patients with a radiocephalic AVF. CONCLUSION Even within the normal range, free testosterone has a significant positive correlation with lumbar spine BMD with no significant association with the forearm or hip BMD.

Abstract
Despite improved patient and clinical outcomes, living donor kidney transplantation is underutilized in the United Kingdom, particularly among minority ethnic groups, compared to deceased donor kidney transplantation. This may in part be due to the way in which kidney services present information about treatment options. With a focus on ethnicity, semi structured interviews captured the views of 19 kidney healthcare professionals from two renal centres in West Yorkshire, about the decisional needs and context within which people with advanced kidney disease make transplant decisions. Data were analysed using thematic analysis. Themes were categorized into three groups: 1) Kidney healthcare professionals: language, cultural awareness, trusted personnel, and staff diversity, 2) Patient information resources: timing and setting of education and suitability of patient-facing information and, 3) People with advanced kidney disease: knowledge, risk perception, and cultural/religious beliefs. To our knowledge, this is the first study in the United Kingdom to investigate in depth, healthcare professionals' views on living donor kidney transplantation decision making. Six recommendations for service improvement/delivery to support decision making around living donor kidney transplantation among minority ethnic groups are described.

Abstract
Transplant professionals strive to improve domestic kidney transplantation rates safely, cost efficiently, and ethically, but to increase rates further may wish to allow their recipients and donors to traverse international boundaries. Travel for transplantation presents significant challenges to the practice of transplantation medicine and donor medicine, but can be enhanced if sustainable international registries develop to include low- and low-middle income countries. Robust data collection and sharing across registries, linking pretransplant information to post-transplant information, linking donor to recipient information, increasing living donor transplant activity through paired exchange, and ongoing reporting of results to permit flexibility and adaptability to changing clinical environments, will all serve to enhance kidney transplantation across international boundaries.

Abstract
This retrospective study was performed to analyse if laterality of the retrieved living donor kidney had any effect on donor and recipient outcomes after hand assisted laparoscopic donor nephrectomy (HALDN). 739 donors who underwent HALDN between January 2006 and January 2018 at a large tertiary transplant centre in the United Kingdom were included. Donor outcomes in individuals undergoing right versus left HALDN were compared with respect to conversion rates, morbidity, warm and cold ischaemia times and recipient failure rates, vascular and ureteric complications. 604 (81.7%) underwent left HALDN and 135 (18.3%) underwent right HALDN, mean age was 47.1 years and 46.8 years respectively with comparable gender distribution. The operative time was shorter for the left side (p = 0.003) and improved during the study for the left but not the right side. In recipients who received left kidneys there were more early technical failures observed (8 versus 1) though not statistically significant. Most centres prefer performing a left nephrectomy and recipient surgeons prefer a left kidney for transplantation primarily because of having a longer vein. This large study provides reassurance that right HALDN nephrectomy is a safe procedure with similar outcomes to left HALDN.

Abstract
Background Living kidney donors may face health risks after donation. Age, sex, body mass index, comorbidities, and relationship to the recipient have an impact on lifetime living kidney donor risk. In view of a changing landscape in renal transplantation with increasing organ shortages, the selection criteria for potential donors may have changed over time. Material/Methods We investigated donor demographics and outcomes in a cohort of 760 living kidney donors who donated from 1967 to 2016 at the transplant center in Heidelberg, Germany. Results The living kidney donor age increased from 34.9±11.5 to 53.2±10.2 years, with 11.4% donors aged 65 years in the period from 2011 to 2016. The number of donors with comorbidities at the time of donation increased. The percentage of donors with a history of obesity, hypertension, smoking, and a family history of kidney disease enlarged to 18.6%, 36.1%, 37.0%, and 9.1%, respectively. De novo hypertension was a common problem in more than half of the donors at long-term follow-up, and donor renal function decreased about 30 mL/mi/1.73 m2. Conclusions This detailed analysis of living kidney donor demographics over the last 50 years detected an increased proportion of donors with higher age and comorbidities today. Careful donor selection, regular follow-up visits, and systematic donor registries are required to further improve donor outcomes.

Abstract
Enhanced recovery after surgery (ERAS) reduces complications and shortens hospital stay without increasing readmission or mortality. However, its role in living donor nephrectomy (LDN) has not yet been defined. Medline, Embase, CINAHL, PsycINFO, and Cochrane Central were searched prior to 08/01/21 for all randomized controlled and cohort studies comparing ERAS to standard of care in LDN. The study was registered on PROSPERO (CRD: CRD42019141706). One thousand, three hundred seventy-seven patients were identified from 14 studies (698 patients with ERAS and 679 patients without). There were considerable differences in the protocols used, and compliance with general ERAS recommendations was poor. Meta-analysis of laparoscopic procedures (including hand- and robot-assisted) revealed that duration of stay was significantly reduced by 0.98 days with ERAS (95% CI = 0.36-1.60, P = .002) and opiate requirement by 32.4 mg (95% CI = 1.1-63.7, P = .04). There was no significant difference n readmission rates or complications. Quality of evidence was low to moderate assessed using the GRADE tool. This review suggests there is a positive benefit of ERAS in laparoscopic LDN. However, there was considerable variation in ERAS protocols used, and the quality of evidence was low; as such, a guideline for ERAS in LDN should be developed and validated.
