The management and outcomes of kidney transplant recipients have evolved over the past 3 decades. This study of US patients whose first kidney allograft failed examined long-term trends in subsequent waitlisting, retransplantation, and all-cause mortality.

Retrospective cohort study.

Patients recorded in the US Renal Data System (USRDS) whose first kidney allograft failed between 1990 and 2019.

The 5-year period in which the allograft failure occurred: 1990-1994, 1995-1999, 2000-2004, 2005-2009, 2010-2014, or 2015-2019.

(1) Waitlisting for retransplantation, (2) retransplantation, and (3) all-cause mortality following first allograft failure.

Competing risk survival analyses with the approach described by Fine and Gray used for the outcomes of waitlisting and retransplantation, and Cox proportional hazards models used for the outcome of all-cause mortality.

The absolute number of patients whose allograft failed and who started dialysis increased from 3,197 in 1990 to 5,821 in 2019. Compared with 1990-1994, the rate of waitlisting for a second transplant increased with each subsequent 5-year period, peaking between 2005 and 2009 before decreasing again subsequently. The rate of retransplantation following allograft failure decreased by 9%, 14%, 18%, 7%, and 11% in the sequential 5-year eras; and the mortality rate was 25% lower in 2015-2019 (HR, 0.75 [95% CI, 0.72-0.77]) compared with 1990-1994. Women had a reduced rate of waitlisting (HR, 0.93 [95% CI, 0.91-0.95]) and lower rate of retransplantation (HR, 0.93 [95% CI, 0.91-0.95]) compared with men. Compared with White patients, African American and Hispanic patients had significantly lower rates of waitlisting, retransplantation, and mortality.

Retrospective data that lacks granular clinical information.

During the past 3 decades, among patients whose first kidney allograft failed and subsequently initiated dialysis, the rates of waitlisting for retransplantation increased while the rates of retransplantation and mortality decreased. Disparities based on race, ethnicity, and sex in waitlisting and retransplantation were observed and warrant further investigation.

Kidney allograft failure constitutes the fourth most common cause of dialysis initiation in the United States, and it accounts for 4% to 10% of yearly new dialysis starts globally. Little is known about the trends in the outcomes of patients whose kidney allograft failed. We studied US patients whose first kidney allograft failed between 1990 and 2019 to understand trends in waitlisting for retransplantation, retransplantation, and all-cause mortality after kidney allograft failure. Among patients whose first kidney allograft failed and started dialysis, rates of waitlisting increased and rates of retransplantation and mortality decreased over the past 3 decades. We found racial, ethnic, and sex-based disparities in outcomes. Compared with White patients, African American and Hispanic patients had significantly lower rates of waitlisting, retransplantation, and mortality. Women also had lower rates of waitlisting and retransplantation compared with men.

Treatment strategies for BK polyomavirus (BKPyV) infection in kidney transplant recipients are heterogeneous among clinicians. We aimed to identify the treatment preferences of key stakeholders for BKPyV infection and measure the trade-offs between treatment outcomes.

Adult kidney transplant recipients, caregivers, and clinicians were eligible to participate in a discrete choice experiment between February 2021 and June 2022. The five treatment-related attributes were achieving viral clearance and optimal graft function, as well as reducing the risk of graft loss, acute rejection, and complications. Results were analyzed using multinomial logistic models.

In total, 109 participants (57 kidney transplant recipients, 10 caregivers, and 42 health professionals) were included. The most important attribute was the risk of graft loss, followed by side effects and acute rejection. As the risk of graft loss increased, all participants were less inclined to accept an assigned treatment strategy. For instance, if graft loss risk was increased from 1% to 50%, the probability of uptake of a treatment strategy for BKPyV infection was reduced from 87% to 3%.

Graft loss is the predominant concern for patients, caregivers, and health professionals when deciding on the treatment for BKPyV infection, and should be included in intervention trials of BKPyV infection.

The nominal group technique (NGT) allows stakeholders to directly generate items for needs assessment. The objective was to demonstrate the use of NGT to inform the development of a healthcare app in patients with relapsed myeloma. Healthcare professionals with experience in the care of patients with relapsed/refractory myeloma were invited to participate.

One NGT group was conducted. In the group, health care professionals working in haematology were asked to vote anonymously in order of highest priority, on symptoms previously highlighted by relapsed/refractory myeloma patients in four focus groups.

A total of 18 healthcare professionals working in the area of haematology participated in the NGT discussion; consultants (n=6), haematology registrars (n=2), specialist nurses [Advanced Nurse Practitioner/Clinical Nurse Specialist] (haematology) (n=3), staff nurse (n=1), and "other" health care professionals (n=6). Participants ranged in experience of working with myeloma patients from 2 years to over 27 years. The symptoms voted in highest priority were: Pain, Fatigue, Peripheral Neuropathy, Infection Risk and Steroid Induced Side Effects.

The NGT was an efficient method for obtaining information to inform a healthcare app.

Kidney transplantation (KT) is the optimal form of renal replacement therapy for patients with end-stage renal diseases. However, this health service is not available to all patients, especially in developing countries. The deceased donor KT programs are mostly absent, and the living donor KT centers are scarce. Single-center studies presenting experiences from developing countries usually report a variety of challenges. This review addresses these challenges and the opposing strategies by reviewing the single-center experiences of developing countries. The financial challenges hamper the infrastructural and material availability, coverage of transplant costs, and qualification of medical personnel. The sociocultural challenges influence organ donation, equity of beneficence, and regular follow-up work. Low interests and motives for transplantation may result from high medicolegal responsibilities in KT practice, intense potential psychosocial burdens, complex qualification protocols, and low productivity or compensation for KT practice. Low medical literacy about KT advantages is prevalent among clinicians, patients, and the public. The inefficient organizational and regulatory oversight is translated into inefficient healthcare systems, absent national KT programs and registries, uncoordinated job descriptions and qualification protocols, uncoordinated on-site investigations with regulatory constraints, and the prevalence of commercial KT practices. These challenges resulted in noticeable differences between KT services in developed and developing countries. The coping strategies can be summarized in two main mechanisms: The first mechanism is maximizing the available resources by increasing the rates of living kidney donation, promoting the expertise of medical personnel, reducing material consumption, and supporting the establishment and maintenance of KT programs. The latter warrants the expansion of the public sector and the elimination of non-ethical KT practices. The second mechanism is recruiting external resources, including financial, experience, and training agreements.

Cancer has been identified by kidney transplant recipients as a critically important outcome. The co-occurrence of cancer and kidney transplantation represents a complex intersection of diseases, symptoms, and competing priorities for treatments. Research that focuses on biochemical parameters and clinical events may not capture the priorities of patients. Patient-centered research can improve the relevance and efficiency of research and is particularly pertinent in the setting of cancer and kidney transplantation to facilitate shared decision-making in complex clinical situations. In addition, patient-reported outcomes can facilitate the assessment of patients' experiences, symptom burden, treatment side effects, and quality of life. This review discusses patient-centered research in the context of kidney transplantation and cancer, including consumer involvement in research and patient-centered outcomes and their measures and inclusion in core outcome sets.

Despite efforts to provide evidence-based care for people living with kidney disease, health care provider goals and priorities are often misaligned with those of individuals with lived experience of disease. Coupled with competing interests of time, resources, and an abundance of suitable guideline topics, identifying and prioritizing areas of focus for the Canadian nephrology community with a patient-oriented perspective is necessary and important. Similar priority-setting exercises have been undertaken to establish research priorities for kidney disease and to standardize outcomes for kidney disease research and clinical care; however, research priorities are distinct from priorities for guideline development. Inclusion of people living with health conditions in the selection and prioritization of guideline topics is suggested by patient engagement frameworks, though the process to operationalizing this is variable. We propose that the Canadian Society of Nephrology Clinical Practice Guideline Committee (CSN CPGC) takes the opportunity at this juncture to incorporate evidence-based prioritization exercises with involvement of people living with kidney disease and their caregivers to inform future guideline activities. In this protocol, we describe our planned research methods to address this.

To establish consensus-based guideline topic priorities for the CSN CPGC using a modified Delphi survey with involvement of multidisciplinary stakeholders, including people living with kidney disease and their caregivers.

Protocol for a Modified Delphi Survey.

Pilot-tested surveys will be distributed via email and conducted using the online platform SurveyMonkey, in both French and English.

We will establish a group of multidisciplinary clinical and research stakeholders (both within and outside CSN membership) from Canada, in addition to people living with kidney disease and/or their caregivers.

A comprehensive literature search will be conducted to generate an initial list of guideline topics, which will be organized into three main categories: (1) International nephrology-focused guidelines that may require Canadian commentary, (2) Non-nephrology specific guidelines from Canada that may require CSN commentary, and (3) Novel topics for guideline development. Participants will engage in a multi-round Modified Delphi Survey to prioritize a set of "important guideline topics."

Consensus will be reached for an item based on both median score on the Likert-type scale (≥ 7) and the percentage agreement (≥ 75%); the Delphi process will be complete when consensus is reached on each item. Guideline topics will then be given a priority score calculated from the total Likert ratings across participants, adjusted for the number of participants.

Potential limitations include participant response rates and compliance to survey completion.

We propose to incorporate evidence-based prioritization exercises with the engagement of people living with kidney disease and their caregivers to establish consensus-based guideline topics and inform future guidelines activities of the CSN CPGC.

Gastrointestinal (GI) symptoms in kidney transplant are common and debilitating. We aimed to ascertain patients' preferences for GI symptom management options to help future interventions align with treatment priorities.

A discrete choice experiment was conducted with kidney transplant recipients in 3 Australian nephrology units. A multinomial logit model was used to quantify the preferences and trade-offs between 5 characteristics: cost, formulation, symptom burden, dietary changes, and medication quantities.

Seventy patients participated (mean age ± SD: 47 ± 15 years, 56% female), 57% had GI symptoms. Patients preferred interventions that will achieve complete resolution of GI symptoms compared to no improvement (odds ratio [95% confidence interval]: 15.3 [1.80, 129.50]), were delivered as a tablet rather than a sachet (1.6 [1.27, 2.08]), retained their current diet compared to eliminating food groups (6.0 [2.19, 16.27]), reduced medication burden (1.4 [1.06, 1.79]), and had lower costs (0.98 [0.96, 1.00]). Participants would be willing to pay AUD$142.20 [$83.90, $200.40] monthly to achieve complete resolution of GI symptoms or AUD$100.90 [$9.60, $192.10] to have moderate improvement in symptoms.

Interventions that are highly effective in relieving all GI symptoms without the need for substantive dietary changes, and in tablet form, are most preferred by kidney transplant recipients.

New immunosuppressive therapies that improve long-term graft survival are needed in kidney transplant. Critical Path Institute's Transplant Therapeutics Consortium received a qualification opinion for the iBOX Scoring System as a novel secondary efficacy endpoint for kidney transplant clinical trials through European Medicines Agency's qualification of novel methodologies for drug development. This is the first qualified endpoint for any transplant indication and is now available for use in kidney transplant clinical trials. Although the current efficacy failure endpoint has typically shown the noninferiority of therapeutic regimens, the iBOX Scoring System can be used to demonstrate the superiority of a new immunosuppressive therapy compared to the standard of care from 6 months to 24 months posttransplant in pivotal or exploratory drug therapeutic studies.

Organ shortage is a major barrier in transplantation and rules guarding organ allocation decisions should be robust, transparent, ethical and fair. Whilst numerous allocation strategies have been proposed, it is often unrealistic to evaluate all of them in real-life settings. Hence, the capability of conducting simulations prior to deployment is important. Here, we developed a kidney allocation simulation framework (simKAP) that aims to evaluate the allocation process and the complex clinical decision-making process of organ acceptance in kidney transplantation. Our findings have shown that incorporation of both the clinical decision-making and a dynamic wait-listing process resulted in the best agreement between the actual and simulated data in almost all scenarios. Additionally, several hypothetical risk-based allocation strategies were generated, and we found that these strategies improved recipients' long-term post-transplant patient survival and reduced wait time for transplantation. The importance of simKAP lies in its ability for policymakers in any transplant community to evaluate any proposed allocation algorithm using in-silico simulation.

The objective of this study was to investigate kidney recipients' experiences within deceased and living donation contexts and, in the latter, by donor relationship type, to identify differences by context and mechanisms by which the relationship with the donor may impact recipients' psychosocial well-being. Individual interviews were conducted with 12 participants and analyzed using Interpretative Phenomenological Analysis. Three themes emerged: (a) salience of and sensitivity toward sacrifice and loss, (b) honoring the sacrifice by honoring the gift, and (c) relational imbalance mirroring perceived burden of donation. Findings were contextualized in relation to the transplantation literature, and their clinical implications discussed.

We report a case of a patient presenting with subacute neurological symptoms 10 years postkidney transplant. Cognitive deficits included acalculia and left upper limb dysesthesia, progressing to hemiplegic upper motor neuron weakness. Investigations included an MRI with multiple FLAIR hyperintensities, while a lumbar puncture was sterile with negative flow cytometry. Ultimately, PCR testing for John Cunningham virus was positive on cerebrospinal fluid. The diagnosis of progressive multifocal leukoencephalopathy (PML) was confirmed on the basis of the above.Initially, the patient was managed with withdrawal of immunosuppressants and close observation. Mirtazapine was commenced based on case reports of successful use in non-transplant patients; the patient's recovery was temporally related to withdrawal of immunosuppression and increasing mirtazapine dosage. The patient is currently maintained on prednisolone and mirtazapine with stable graft function and improved mobility and cognitive function.

Posttransplant diabetes (PTD) is a common medical complication after solid organ transplantation. Because of adverse outcomes associated with its development and detrimental impact on long-term survival, strategies to prevent or manage PTD are critically important but remain underresearched. Treatment hierarchies of antidiabetic therapies in the general population are currently being revolutionized based on cardiovascular outcome trials, providing evidence-based rationale for optimization of medical management. However, opportunities for improving medical management of PTD are challenged by 2 important considerations: (1) translating clinical evidence data from the general population to underresearched solid organ transplant cohorts and (2) targeting treatment based on primary underlying PTD pathophysiology. In this article, the aim is to provide an overview of PTD treatment options from a new angle. Rationalized by a consideration of underlying PTD pathophysiological defects, which are heterogeneous among diverse transplant patient cohorts, a critical appraisal of the published literature and summary of current research in progress will be reviewed. The aim is to update transplant professionals regarding medical management of PTD from a new perspective tailored therapeutic intervention based on individualized characteristics. As the gap in clinical evidence between management of PTD versus type 2 diabetes widens, it is imperative for the transplant community to bridge this gap with targeted clinical trials to ensure we optimize outcomes for solid organ transplant recipients who are at risk or develop PTD. This necessary clinical research should help efforts to improve long-term outcomes for solid transplant patients from both a patient and graft survival perspective.

Despite an increased cancer risk for patients with chronic kidney disease (CKD), uptake of cancer screening varies due to competing priorities and complex health-related issues. This study aimed to elicit the preferences and important attributes of cancer screening in patients with CKD.

An on-line best-worst scaling survey was used to ascertain the relative importance of 22 screening attributes among CKD patients using an incomplete block design. Preference scores (0-1) were calculated by multinomial logistic regression. Preference heterogeneity was evaluated.

The survey was completed by 83 patients: 26 not requiring kidney replacement therapy, 20 receiving dialysis and 37 transplant recipients (mean age 59 years, 53% men, 75% prior to cancer screening). The five most important attributes were early detection {preference score 1.0 [95% confidence interval (CI) 0.90-1.10]}, decreased risk of cancer death [0.85 (0.75-0.94)], false negatives [0.71 (0.61-0.80)], reduction in immunosuppression if detected [0.68 (0.59-0.78)] and non-invasive interventions after positive results [0.68 (0.59-0.78)]. Preference heterogeneity reflected the stage of CKD. Immunosuppression reduction [mean difference 0.11 (95% CI 0.02-0.19)] and views of family/friends [0.10 (reference attribute)] were important for transplant recipients. Screening frequency [-0.18 (95% CI -0.26 to -0.10)] and overdiagnosis of harmless cancers [-0.14 (95% CI -0.22 to -0.10)] were important for dialysis patients.

Early detection, risk of cancer-related death, false negatives, immunosuppression reduction and non-invasive interventions following detection are important cancer screening considerations among CKD patients. Patient preferences are key to shared decision-making and individualized cancer screening.

Cutaneous squamous cell carcinoma (CSCC) is a major cause of morbidity and mortality after organ transplant. Many patients subsequently develop multiple CSCC following a first CSCC, and the risk of metastasis and death is significantly increased compared to the general population. Post-transplant CSCC represents a disease at the interface of dermatology and transplant medicine. Both systemic chemoprevention and modulation of immunosuppression are frequently employed in patients with multiple CSCC, yet there is little consensus on their use after first CSCC to reduce risk of subsequent tumors. While relatively few controlled trials have been undertaken, extrapolation of observational data suggests the most effective interventions may be at the time of first CSCC. We review the need for intervention after a first post-transplant CSCC and evidence for use of various approaches as secondary prevention, before discussing barriers preventing engagement with this approach and finally highlight areas for future research. Close collaboration between specialties to ensure prompt deployment of these interventions after a first CSCC may improve patient outcomes.

Cancer is an important outcome in kidney transplantation, but the scope and consistency of how cancer is defined and reported in trials involving kidney transplant recipients has not been evaluated. This study aimed to assess the range and variability of cancer outcomes in trials involving kidney transplant recipients.

The ClinicalTrials.gov database was searched from February 2000 to July 2021 to identify all randomized controlled trials (RCTs) in adult kidney transplant recipients, and which included cancer as a specified outcome. The definition of cancer, types of cancer (if any), timepoint(s) of measurement and method of aggregation were extracted for each cancer outcome.

Of the 819 trials in kidney transplantation, only 84 (10%) included 1 or more cancer outcomes. Of these, 72 of 84 (86%) trials included cancer as a secondary outcome and 12 of 84 (14%) considered cancer as a primary outcome. The most frequent description of cancer was "malignancy" (n = 44, 43%), without reference to diagnostic criteria, histology, grade, or stage. The 2 most common cancer types were posttransplant lymphoproliferative disorder (PTLD) (n = 20, 20%) and nonmelanoma skin cancer (n = 10, 10%). Several methods of aggregation were identified, including incidence or rate (n = 47, 46%), frequency or proportion (n = 30, 29%), and time to event (n = 5, 5%). Approximately half the cancer outcomes were measured at a single time point (n = 44, 52%).

Cancer is an infrequently reported outcome and is inconsistently defined in trials of kidney transplant recipients. Consistent reporting of cancer outcomes using standardized definitions would provide important information on the impact of cancer in patients after kidney transplantation.

Although kidney transplantation is the best treatment for kidney failure, scarce research has examined its effects on physical activity, physical function and quality of life.

To investigate the experiences of a group of adults living with advanced kidney disease focusing on quality of life, physical activity and function and to see how findings differ in a group of kidney transplant recipients.

Individual semi-structured interviews were conducted with adults with advanced kidney disease (n = 10; 70.5 ± 8.9 years) and adults who had received a kidney transplant (n = 10; 50.7 ± 11.5 years; transplant age: 42.7 ± 20.9 months). Interviews were transcribed verbatim, thematically analysed and composite vignettes developed.

Individuals with advanced kidney disease described a sense of loss and alteration to their life plans. Kidney transplant recipients reported increased freedom, independence and a return to near normality, with improved quality of life, physical activity and function compared with their pre-transplant lives. However, transplant recipients also described living with anxiety about the health of their transplant and fear it may fail.

Whilst adults living with advanced kidney disease often experience a reduced quality of life, physical activity and function, kidney transplantation can help facilitate a return to pre-disease levels of physical activity, physical function and quality of life. However, transplant recipients also reported living with anxiety around their new kidney failing. This study demonstrates the variability in the lived experiences of adults living with advanced kidney disease or a kidney transplant and highlights the need for patient-centred care.

In Aotearoa/New Zealand, Indigenous Māori experience inequitable delivery of kidney transplantation despite disproportionately higher rates of kidney failure. This study describes Māori patients' and families' values, perspectives, and experiences related to kidney transplantation.

Qualitative interview study.

We conducted 40 in-depth interviews of 40 Māori: 8 who had received a transplant, 20 with chronic kidney disease (which included 10 on the deceased donor transplant list, 9 who were interested in transplantation and not currently waitlisted or who were ineligible for waitlisting, and 1 who was not interested in transplantation), 4 live-kidney donors, and 8 family members including 6 who had experiences with donor assessment.

Data were analyzed inductively to generate themes and a conceptual framework.

We identified 5 major themes: actively seeking a kidney transplant; evolving attitudes toward traditional values and practices; being confronted by interpersonal and systemic racism; poor information and communication; and challenged by social determinants of health.

Participants were recruited nationally through patient advocacy organizations and 1 regional kidney service. Potential participants unrelated to these groups or region could not be included.

Māori participants were highly motivated to seek kidney transplantation and were inspired by positive experiences through donating and receiving a kidney. However, they faced barriers including social determinants, racism, and lack of information that impacted both direct experiences of transplantation and access to transplantation services.

Medicine-taking among transplant recipients is a complex and ubiquitous task with significant impacts on outcomes. This study aimed to describe the perspectives and experiences of medicine-taking in adult solid organ transplant recipients. Electronic databases were searched to July 2020, and thematic synthesis was used to analyze the data. From 119 studies (n = 2901), we identified six themes: threats to identity and ambitions (impaired self-image, restricting goals and roles, loss of financial independence); navigating through uncertainty and distrust (lacking tangible/perceptible benefits, unprepared for side effects, isolation in decision-making); alleviating treatment burdens (establishing and mastering routines, counteracting side effects, preparing for the unexpected); gaining and seeking confidence (clarity with knowledge, reassurance through collective experiences, focusing on the future outlook); recalibrating to a new normal posttransplant (adjusting to ongoing dependence on medications, in both states of illness and health, unfulfilled expectations); and preserving graft survival (maintaining the ability to participate in life, avoiding rejection, enacting a social responsibility of giving back). Transplant recipients take medications to preserve graft function, but dependence on medications jeopardizes their sense of normality. Interventions supporting the adaptation to medicine-taking and addressing treatment burdens may improve patient satisfaction and capacities to take medications for improved outcomes.

Improved recognition of factors influencing graft survival has led to better short-term kidney transplant outcomes. However, efforts to prevent long-term graft decline and improve graft survival have seen more modest improvements. The adoption of electronic health records has enabled better recording and identification of donor-recipient factors through the use of modern statistical techniques. We have previously shown in a prevalent renal transplant population that episodes of rapid deterioration are associated with graft loss.

Estimated glomerular filtration rates (eGFR) between 3 and 27 months after transplantation were collected from 310 kidney transplant recipients. We utilised a Bayesian approach to estimate the most likely eGFR trajectory as a smooth curve from an average of 10,000 Monte Carlo samples. The probability of having an episode of rapid deterioration (decline greater than 5 ml/min/1.73 m2 per year in any 1-month period) was calculated. Graft loss and mortality data was collected over a median follow-up period of 8 years. Factors associated with having an episode of rapid deterioration and associations with long-term graft loss were explored.

In multivariable Cox Proportional Hazard analysis, a probability greater than 0.8 of rapid deterioration was associated with long-term death-censored graft loss (Hazard ratio 2.17; 95% Confidence intervals [CI] 1.04-4.55). In separate multivariable logistic regression models, cytomegalovirus (CMV) serostatus donor positive to recipient positive (Odds ratio [OR] 3.82; 95%CI 1.63-8.97), CMV donor positive (OR 2.06; 95%CI 1.15-3.68), and CMV recipient positive (OR 2.03; 95%CI 1.14-3.60) were associated with having a greater than 0.8 probability of an episode of rapid deterioration.

Early episodes of rapid deterioration are associated with long-term death-censored graft loss and are associated with cytomegalovirus seropositivity. Further study is required to better manage these potentially modifiable risks factors and improve long-term graft survival.

While much research exists regarding medical outcomes for pediatric end stage renal disease (ESRD) populations and for adults receiving dialysis or kidney transplant, the understanding of long-term psychosocial outcomes for individuals diagnosed with ESRD or transplanted in childhood remains limited. A literature review was undertaken by two social work researchers to identify relationship, education, employment, and quality of life (QOL) outcomes for this population utilizing PUBMED and PsycInfo databases. Inconsistencies in the MeSH terms and keywords used across the relevant articles were noted. The impact of transplantation in childhood is significant across multiple facets of social development including but not limited to peer/intimate relationships, education and employment and QOL, and overall well-being. When compared to healthy peers, those with ESRD were delayed in all areas of social development. While improvements in psychosocial outcomes have occurred alongside improved graft and patient survival, more focused longitudinal and qualitative inquiry is needed. Partnerships are needed across disciplines and across those caring for different age cohorts in pediatric, adult nephrology, and transplant practices.

This study aimed at exploring the perceptions and experiences of female burn survivors with facial disfigurement in Pakistan.

Two different quantitative and qualitative studies were conducted, of which the data were collected from 100 burn patients. A pilot interview protocol was developed. An indepth interview of five female burn survivors with facial disfigurement was taken in Lahore, Pakistan. The transcripts were analyzed using thematic analysis and four major themes were identified, respectively physical appearance, posttraumatic growth, relationships and coping strategies.

Thematic analysis reflected differences in attributional style, perceptions and individual experiences of female burn survivors with facial disfigurement. The study showed the importance of physical appearance for different burn survivors and how their life had changed after suffering from a burn injury.

It could be easy to have a positive outlook towards life and accept visible differences post injury for the burn survivors, who are grateful for life, get a strong family support and have available resources. On the contrary, with low self-esteem, lack of a family support and available resources, patients would be dissatisfied with their life.

To investigate patients' existential experiences in everyday life after a kidney transplantation with a living donor.

A qualitative study anchored in a hermeneutic-phenomenological approach inspired by Ricoeur's theory of narrative and interpretation.

Eleven patient interviews were conducted approximately 6 months after a kidney transplantation with a living donor. The interviews were conducted between August 2017-May 2019. Analysis and interpretation are based on Ricoeur's theory of interpretation.

Four themes were identified: Experiencing bodily vulnerability while getting back to life; Feeling guilt while experiencing gratitude; Living in limbo while one's identity is changing; and Facing the future with hope while having reservations.

This study reveals that patients experience multifaceted existential challenges in their everyday lives during the transition of the kidney transplantation process. Post-surgery complications for donors lead to feelings of guilt in patients; plus, they must adapt to a new existence, including a new identity. The patients feel they are in limbo, as they experience their existence as uncertain and their identity as unknown.

The study highlights a need for developing a rehabilitation programme to address the individual and various existential challenges faced by patients who need to undergo a kidney transplantation.

New-onset diabetes is common after kidney transplantation, but the benefit of lifestyle intervention to improve glucose metabolism posttransplantation is unproven.

We conducted a single-center, randomized controlled trial involving 130 nondiabetic kidney transplant recipients with stable function between 3 and 24 months post-transplantation. Participants were randomly assigned in a 1:1 ratio to receive active intervention (lifestyle advice delivered by renal dietitians using behavior change techniques) versus passive intervention (leaflet advice alone). Primary outcome was 6-month change in insulin secretion, insulin sensitivity, and disposition index. Secondary outcomes included patient-reported outcomes, cardiometabolic parameters, clinical outcomes, and safety endpoints.

Between August 17, 2015 and December 18, 2017, 130 individuals were recruited, of whom 103 completed the study (drop-out rate 20.8%). Active versus passive intervention was not associated with any change in glucose metabolism: insulin secretion (mean difference, -446; 95% confidence interval [CI], -3184 to 2292; P = 0.748), insulin sensitivity (mean difference, -0.45; 95% CI, -1.34 to 0.44; P = 0.319), or disposition index (mean difference, -940; 95% CI, -5655 to 3775; P = 0.693). Clinically, active versus passive lifestyle intervention resulted in reduced incidence of posttransplantation diabetes (7.6% versus 15.6%, respectively, P = 0.123), reduction in fat mass (mean difference, -1.537 kg; 95% CI, -2.947 to -0.127; P = 0.033), and improvement in weight (mean difference, -2.47 kg; 95% CI, -4.01 to -0.92; P = 0.002). No serious adverse events were noted.

Active lifestyle intervention led by renal dietitians did not improve surrogate markers of glucose metabolism. Further investigation is warranted to determine if clinical outcomes can be improved using this methodology.

We aimed to develop an adapted information-motivation-behavioral skills (IMB) model to describe barriers and facilitators for adherence and self-management among kidney transplant recipients.

We conducted a review of literature about kidney transplant recipients' knowledge, perceptions, and experiences and organized our results using the IMB framework. We then conducted interviews with transplant recipients and transplant providers to supplement our literature search.

Our proposed adaption of the IMB model describes informational, motivational, and behavioral skills barriers and facilitators for medication adherence and self-management among kidney transplant recipients. Moderating factors influence not only behavioral skills, but also recipients' understanding of information and motivation to adhere and practice self-management.

By using the IMB model to organize current research and interviews with recipients and providers, we developed an adapted model for medication adherence and self-management. Results are promising to impact future educational and behavioral interventions for kidney transplant recipients.

Appropriate metrics for performance analysis is an active topic of debate within the transplant community. This study explores current proposals on metric expansion as well as potential metrics and prospective collaborations that have not received widespread discussion within the transplant community. The premature introduction of additional, nonvalidated metrics risks behaviors that may undermine donor utilization and patient access to transplantation.

Epidemiologic studies have linked urinary oxalate excretion to risk of chronic kidney disease (CKD) progression and end-stage renal disease. We aimed to investigate whether urinary oxalate, in stable kidney transplant recipients (KTR), is prospectively associated with risk of graft failure. In secondary analyses we evaluated the association with post-transplantation diabetes mellitus, all-cause mortality and specific causes of death. Oxalate excretion was measured in 24-h urine collection samples in a cohort of 683 KTR with a functioning allograft ≥1 year. Mean eGFR was 52 ± 20 mL/min/1.73 m2. Median (interquartile range) urinary oxalate excretion was 505 (347-732) µmol/24-h in women and 519 (396-736) µmol/24-h in men (p = 0.08), with 302 patients (44% of the study population) above normal limits (hyperoxaluria). A consistent and independent inverse association was found with all-cause mortality (HR 0.77, 95% CI 0.63-0.94, p = 0.01). Cause-specific survival analyses showed that this association was mainly driven by an inverse association with mortality due to infection (HR 0.56, 95% CI 0.38-0.83, p = 0.004), which remained materially unchanged after performing sensitivity analyses. Twenty-four-hour urinary oxalate excretion did not associate with risk of graft failure, post-transplant diabetes mellitus, cardiovascular mortality, mortality due to malignancies or mortality due to miscellaneous causes. In conclusion, in KTR, 24-h urinary oxalate excretion is elevated in 44% of KTR and inversely associated with mortality due to infectious causes.

Patients with chronic kidney disease (CKD) have an increased risk of cancer compared with the general population. Despite this, there is considerable variability in cancer screening practices among nephrologists that may reflect uncertainties about the benefits and harms of screening, the additional costs, and competing priorities among the complex issues that patients are confronted with. We aimed to describe nephrologists' perspectives and approaches to cancer screening in CKD.

Semi-structured interviews were conducted with 29 nephrologists from 15 units across Australia and New Zealand. Interviews were transcribed and thematically analyzed.

Five themes were identified: empowering patients to make informed decisions (respecting patient preferences, communicating evidence-based recommendations, creating awareness of consequences, preparing for transplantation); justifiable risk taking (avoiding undue consequences in vulnerable populations, balancing the costs and benefits, warranted by long term immunosuppression, assurance of reasonable survival gains); ambiguity of evidence in supporting decisions (absence of standardized recommendations, limited transferability of population-based data); depending on a shared multidisciplinary approach (collaboration with primary health care, access to coordinated skin cancer clinics); and prioritizing current or imminent complications.

Nephrologists approach decisions about cancer screening in patients with CKD based on patient preferences, assessment of risk, justifiable survival gains, and current health priorities. Evidence-based guidelines, communication frameworks and specialist clinics may support informed and shared decision making about cancer screening in CKD.

The effect of a kidney transplant on a recipient extends beyond the restoration of kidney function. However, there is limited qualitative analysis of recipient perspectives on life following transplantation, particularly in the United States. To understand the full patient experience, it is necessary to understand recipient views on life adjustments after kidney transplantation, medical management, and quality of life. This could lead to improvements in recipient care and sense of well-being.

We conducted a paper-based survey from March 23 to October 1, 2015 of 476 kidney transplant recipients at the University of Michigan Health System in Ann Arbor, Michigan. We analyzed their open-ended responses using qualitative research methods. This is a companion analysis to a previous quantitative report on the closed-ended responses to that survey.

Common themes relating to changes following transplantation included: improvements in quality of life, a return to normalcy, better health and more energy. Concerns included: duration of graft survival, fears about one day returning to dialysis or needing to undergo another kidney transplant, comorbidities, future quality of life, and the cost and quality of their healthcare. Many recipients were grateful for their transplant, but some were anxious about the burdens transplantation placed on their loved ones.

While most recipients reported meaningful improvements in health and lifestyle after kidney transplantation, a minority of participants experienced declines in energy or health status. Worries about how long the transplant will function, future health, and cost and quality of healthcare are prevalent. Future research could study the effects of providing additional information, programs, and interventions following transplantation that target these concerns. This may better prepare and support kidney recipients and lead to improvements in the patient experience.

A robust relationship between procedure volume and clinical outcomes has been demonstrated across many surgical fields. This study assessed whether a center volume-outcome relationship exists for contemporary kidney transplantation, specifically for diabetic recipients, older recipients (aged ≥65 years), and recipients of high kidney donor profile index (KDPI ≥ 85) kidneys.

Retrospective cohort study.

Adult kidney-only transplant recipients who underwent transplantation between 2009 and 2013 (N = 79,581).

The primary exposure variable was center volume, categorized into quartiles based on the total kidney transplantation volume. Quartile 1 (Q1) centers performed a mean of fewer than 66 kidney transplantations per year, whereas Q4 centers performed a mean of more than 196 kidney transplantations per year.

All-cause graft failure and mortality within 3 years of transplantation.

Multivariable Cox frailty models were used to adjust for donor characteristics, recipient characteristics, and cold ischemia time.

Minor differences in rates of 3-year deceased donor all-cause graft failure across quartiles of center volume were observed (14.9% for Q1 vs 16.7% for Q4), including in subgroups (diabetic recipients, 18.4% for Q1 vs 19.7% for Q4; older recipients, 19.4% for Q1 vs 22.5% for Q4; recipients of high KDPI kidneys, 26.5% for Q1 vs 26.5% for Q4). Results were similar for 3-year mortality. After adjustment for donor, recipient, and graft characteristics using Cox regression, center volume was not significantly associated with all-cause graft failure or mortality within 3 years, except that diabetic recipients at Q3 centers had slightly lower mortality (compared with Q1 centers, adjusted HR of 0.85 [95% CI, 0.73-0.99]).

Potential unmeasured confounding from patient comorbid conditions and organ selection.

These findings provide little evidence that care in higher volume centers is associated with better adjusted outcomes for kidney transplant recipients, even in populations anticipated to be at increased risk for graft failure or death.

This study examined whether kidney transplant recipients' post-transplant goals and expectations align with those as perceived by their healthcare providers.

Post-transplant goals and expectations across four domains were assessed via a descriptive survey of healthcare providers (N=72) and kidney transplant recipients (N=476) at the University of Michigan from March 23 - October 1, 2015. Demographic and transplant-related data were collected via a retrospective review of medical records, and survey responses were compared using Chi-square tests, Wilcoxon two-sample tests, and logistic regression.

Patients expressed higher quality of life (mean Neuro-QOL T-score 60.2 vs. 52.7), were less likely to report that they were currently experiencing complications (11% vs. 24%), and anticipated their transplants to last longer (median 25 vs. 15 years) and to live longer (median 80 vs. 71 years) than providers expected for their typical patient. However, provider perceptions of patients' future ability to feel well, perform daily activities and work were significantly higher than those expressed by patients (all p<0.05).

Kidney transplant patient and provider expectations differ in significant ways.

Identified areas of discordance may provide opportunities for patients and providers to better evaluate treatment option tradeoffs in post-transplant clinical interactions.

Subclinical inflammation is an important predictor of death-censored graft loss, and its treatment has been shown to improve graft outcomes. Urine CXCL10 outperforms standard post-transplant surveillance in observational studies, by detecting subclinical rejection and early clinical rejection before graft functional decline in kidney transplant recipients.

This is a phase ii/iii multicentre, international randomised controlled parallel group trial to determine if the early treatment of rejection, as detected by urine CXCL10, will improve kidney allograft outcomes. Incident adult kidney transplant patients (n~420) will be enrolled to undergo routine urine CXCL10 monitoring postkidney transplant. Patients at high risk of rejection, defined as confirmed elevated urine CXCL10 level, will be randomised 1:1 stratified by centre (n=250). The intervention arm (n=125) will undergo a study biopsy to check for subclinical rejection and biopsy-proven rejection will be treated per protocol. The control arm (n=125) will undergo routine post-transplant monitoring. The primary outcome at 12 months is a composite of death-censored graft loss, clinical biopsy-proven acute rejection, de novo donor-specific antibody, inflammation in areas of interstitial fibrosis and tubular atrophy (Banff i-IFTA, chronic active T-cell mediated rejection) and subclinical tubulitis on 12-month surveillance biopsy. The secondary outcomes include decline of graft function, microvascular inflammation at 12 months, development of IFTA at 12 months, days from transplantation to clinical biopsy-proven rejection, albuminuria, EuroQol five-dimension five-level instrument, cost-effectiveness analysis of the urine CXCL10 monitoring strategy and the urine CXCL10 kinetics in response to rejection therapy.

The study has been approved by the University of Manitoba Health Research Ethics Board (HS20861, B2017:076) and the local research ethics boards of participating centres. Recruitment commenced in March 2018 and results are expected to be published in 2023. De-identified data may be shared with other researchers according to international guidelines (International Committee of Medical Journal Editors [ICJME]).
