RESUMEN
Kidney transplant recipients (KTRs) experience more fatigue, anxiety, and depressive symptoms and lower concentration and health-related quality of life (HRQoL) compared with the general population. Anemia is a potential cause that is well-recognized and treated. Iron deficiency, however, is often unrecognized, despite its potential detrimental effects related to and unrelated to anemia. We investigated the interplay of anemia, iron deficiency, and patient-reported outcomes in 814 outpatient KTRs (62% male, age 56 ± 13 years) enrolled in the TransplantLines Biobank and Cohort Study (Groningen, The Netherlands). In total, 28% had iron deficiency (ie, transferrin saturation < 20% and ferritin < 100 µg/L), and 29% had anemia (World Health Organization criteria). In linear regression analyses, iron deficiency, but not anemia, was associated with more fatigue, worse concentration, lower wellbeing, more anxiety, more depressive symptoms, and lower HRQoL, independent of age, sex, estimated glomerular filtration rate, anemia, and other potential confounders. In the fully adjusted logistic regression models, iron deficiency was associated with an estimated 53% higher risk of severe fatigue, a 100% higher risk of major depressive symptoms, and a 51% higher chance of being at risk for sick leave/work disability. Clinical trials are needed to investigate the effect of iron deficiency correction on patient-reported outcomes and HRQoL in KTRs.

PURPOSE OF REVIEW: The opportunity to review the more recent evidence for prescribing exercise-based physical rehabilitation for people living with chronic kidney disease (CKD) is timely. There has been a recent global focus evaluating how physical activity interventions might improve health-related quality of life and outcomes for people living with chronic health conditions in a post-COVID era. There is finally a long overdue commitment from the kidney research and clinical community to deliver pragmatic interventions to help people living with CKD to be able to live well with their condition. RECENT FINDINGS: This article reviews recent research, and discusses the challenges and potential solutions, for providing exercise-based therapeutic options for people living with CKD; including predialysis self-management interventions, options for both prehabilitation and posttransplant rehabilitation, pragmatic considerations for delivery of exercise therapy for people receiving haemodialysis treatment and the role of virtual kidney-specific rehabilitation. SUMMARY: Whilst there remains a need for further research in this area of patient care, there is now a body of evidence and kidney-specific guidelines that firmly support a rollout of pragmatic and scalable exercise-based interventions for people living with CKD. We are indeed nearly there now.

RATIONALE & OBJECTIVE: Prior studies report that the use of proton pump inhibitors (PPIs) can adversely affect gut microbiota and gastrointestinal uptake of micronutrients, in particular iron and magnesium, and are used frequently by kidney transplant recipients. Altered gut microbiota, iron deficiency, and magnesium deficiency have been implicated in the pathogenesis of chronic fatigue. Therefore, we hypothesized that PPI use may be an important and underappreciated cause of fatigue and reduced health-related quality of life (HRQoL) in this population. STUDY DESIGN: Cross-sectional study. SETTING & PARTICIPANTS: Kidney transplant recipients (≥1 year after transplantation) enrolled in the TransplantLines Biobank and Cohort Study. EXPOSURE: PPI use, PPI type, PPI dosage, and duration of PPI use. OUTCOME: Fatigue and HRQoL, assessed using the validated Checklist Individual Strength 20 Revised questionnaire and Short Form-36 questionnaire. ANALYTICAL APPROACH: Logistic and linear regression. RESULTS: We included 937 kidney transplant recipients (mean age 56±13 years, 39% female) at a median of 3 (1-10) years after transplantation. PPI use was associated with fatigue severity (regression coefficient 4.02, 95% CI, 2.18 to 5.85, P<0.001), a higher risk of severe fatigue (OR 2.05, 95% CI, 1.48 to 2.84, P<0.001), lower physical HRQoL (regression coefficient-8.54, 95% CI, -11.54 to-5.54, P<0.001), and lower mental HRQoL (regression coefficient-4.66, 95% CI, -7.15 to-2.17, P<0.001). These associations were independent of potential confounders including age, time since transplantation, history of upper gastrointestinal disease, antiplatelet therapy, and the total number of medications. They were present among all individually assessed PPI types and were dose dependent. Duration of PPI exposure was only associated with fatigue severity. LIMITATIONS: Residual confounding and inability to assess causal relationships. CONCLUSIONS: PPI use is independently associated with fatigue and lower HRQoL among kidney transplant recipients. PPI use might be an easily accessible target for alleviating fatigue and improving HRQoL among kidney transplant recipients. Further studies examining the effect of PPI exposure in this population are warranted. PLAIN-LANGUAGE SUMMARY: In this observational study, we investigated the association of proton pump inhibitors with fatigue and health-related quality of life among kidney transplant recipients. Our data showed that proton pump inhibitors were independently associated with fatigue severity, severe fatigue, and lower physical and mental health-related quality of life. These associations were present among all individually assessed proton pump inhibitor types and were dose dependent. While we await future studies on this topic, proton pump inhibitor use might be an easily accessible target for alleviating fatigue and improving health-related quality of life among kidney transplant recipients.

BACKGROUND: Cognitive impairment is often present shortly after transplantation in kidney transplant recipients (KTR). To date, it is unknown whether these impairments persist in thelong term, to what extent they are associated with disease-related variables and whether they affect societal participation and quality of life (QoL) of KTR. METHOD: This study was part of the TransplantLines Biobank & Cohort Study in the University Medical Center Groningen. A total of 131 KTR, with a mean age of 53.6 years (SD = 13.5) transplanted ≥1 year ago (M = 11.2 years, range 1-41.7 years), were included and compared with 306 healthy controls (HC). KTR and HC were well matched; there were no significant differences regarding age, sex and education. All participants were assessed with neuropsychological tests measuring memory, mental speed, attention and executive functioning, and with questionnaires examining societal participation and QoL. RESULTS: Compared with HC, KTR performed significantly worse on memory, mental speed and measures of executive functioning (all P-values <0.05). Moreover, 16% of KTR met the criteria for mild cognitive impairment (MCI), compared with 2.6% of the HC. MCI in KTR was not significantly correlated with age- and disease-related variables. Poorer cognitive functioning was significantly related to lower levels of societal participation and to lower QoL (all P-values <0.01). CONCLUSIONS: This study shows long-term cognitive impairments in KTR, which are not related to disease-related variables. Neuropsychological assessment is important to timely signal these impairments, given their serious negative impact on societal participation and QoL.

BACKGROUND: Fatigue and impaired health-related quality of life (HRQoL) are common among kidney transplant recipients (KTR). We hypothesized that both may partially be attributable to poor sleep. METHODS: Cross-sectional and longitudinal data of KTR enrolled in the TransplantLines Biobank and Cohort Study were used. Sleep quality was assessed using the Pittsburgh Sleep Quality Index questionnaire. Individual strength (i.e. a composite of fatigue, concentration, motivation and physical activity), societal participation and HRQoL were assessed using validated questionnaires. RESULTS: We included 872 KTR (39% female, age 56 ± 13 years) and 335 healthy controls. In total, 33% of male KTR and 49% of female KTR reported poor sleep quality, which was higher compared with male and female healthy controls (19% and 28%, respectively, P < .001 for both). In logistic regression analyses, female sex, anxiety, active smoking, low protein intake, physically inactive lifestyle, low plasma magnesium concentration, using calcineurin inhibitors, not using mTOR inhibitors and using benzodiazepine agonists were associated with poor sleep quality. In adjusted linear regression analyses, poor sleep was strongly and independently associated with lower individual strength [standardized ß (st.ß) = 0.59, 95% confidence interval (CI) 0.45 to 0.74, P < .001], poorer societal participation (frequency: st.ß = -0.17, 95% CI -0.32 to -0.01, P = .04; restrictions: st.ß = -0.36, 95% CI -0.51 to -0.21, P < .001; satisfaction: st.ß = -0.44, 95% CI -0.59 to -0.28, P < .001) and lower HRQoL (physical: st.ß = -0.53, 95% CI -0.68 to -0.38, P < .001; mental: st.ß = -0.64, 95% CI -0.78 to -0.50, P < .001). The associations with poorer societal participation and lower HRQoL were strongly mediated by individual strength (P < .001 for all), yet the suggested direct effects of poor sleep quality on HRQoL remained significant (Pphysical = .03, Pmental = .002). Longitudinal data of 292 KTR showed that sleep quality improves after kidney transplantation in males (P < .001), but not in females (P = .9). CONCLUSIONS: Poor sleep quality is common among KTR, and may be a potential target to improve fatigue, societal participation and HRQoL among KTR.

There is increasingly growing evidence and awareness that prehabilitation in waitlisted solid organ transplant candidates may benefit clinical transplant outcomes and improve the patient's overall health and quality of life. Lifestyle changes, consisting of physical training, dietary management, and psychosocial interventions, aim to optimize the patient's physical and mental health before undergoing surgery, so as to enhance their ability to overcome procedure-associated stress, reduce complications, and accelerate post-operative recovery. Clinical data are promising but few, and evidence-based recommendations are scarce. To address the need for clinical guidelines, The European Society of Organ Transplantation (ESOT) convened a dedicated Working Group "Prehabilitation in Solid Organ Transplant Candidates," comprising experts in physical exercise, nutrition and psychosocial interventions, to review the literature on prehabilitation in this population, and develop recommendations. These were discussed and voted upon during the Consensus Conference in Prague, 13-15 November 2022. A high degree of consensus existed amongst all stakeholders including transplant recipients and their representatives. Ten recommendations were formulated that are a balanced representation of current published evidence and real-world practice. The findings and recommendations of the Working Group on Prehabilitation for solid organ transplant candidates are presented in this article.

BACKGROUND: Diarrhea is a well-known side effect of mycophenolic acid (MPA) use in kidney transplant recipients (KTRs). It is unknown whether self-reported diarrhea using the Modified Transplant Symptom Occurrence and Symptom Distress Scale (MTSOSD-59R) corresponds to stool water content and how both relate to MPA usage. METHODS: MTSOSD-59R questionnaires filled out by 700 KTRs from the TransplantLines Biobank and Cohort Study (NCT03272841) were analyzed and compared with stool water content. Stool samples (N = 345) were freeze-dried, and a water content ≥80% was considered diarrhea. RESULTS: Self-perceived diarrhea was reported by 46%, while stool water content ≥80% was present in 23% of KTRs. MPA use was not associated with self-perceived diarrhea (odds ratio(OR) 1.32; 95% confidence interval(CI), 0.87-1.99, p = .2), while it was associated with stool water content ≥80% (OR 2.88; 95%CI, 1.41-5.89, p = .004), independent of potential confounders. Adjustment for prior MPA discontinuation because of severe diarrhea, uncovered an association between MPA use and self-perceived diarrhea (OR 1.80; 95%CI, 1.13-2.89, p = .01). CONCLUSIONS: These results suggest that reporting bias could add to the discrepancy between both methods for diarrhea assessment. We recommend use of objective biomarkers or more extensive questionnaires which assess information on stool frequency and stool consistency, to investigate post-transplantation diarrhea.

OBJECTIVE: The aims of the study were to examine whether distinct trajectories of anxious and depressive symptoms are present among liver transplant recipients from before transplantation to 2 years afterward, to identify associated demographic, clinical, and individual characteristics, and to examine the influence of distinct trajectories on outcomes. METHODS: A prospective, multicenter cohort study was performed among 153 liver transplant recipients. Data were retrieved using questionnaires administered before transplantation and at 3, 6, 12, and 24 months after transplantation. Clinical data were retrieved by medical record review. Latent class growth analysis was used to identify distinct trajectories. χ test, analyses of variance, and multinomial logistic regression were used to identify associated variables and the impact of the distinct trajectories on outcomes. RESULTS: Three distinct trajectories for symptoms of anxiety (State-Trait Anxiety Inventory-short form) as well as depression (Center for Epidemiological Studies Depression Scale) were identified: "no symptoms," "resolved symptoms," and "persistent symptoms." The trajectories of persistent anxiety and depression comprised, respectively, 23% and 29% of the transplant recipients. Several clinical and individual variables were associated with the trajectories of persistent anxiety and/or depression: experiencing more adverse effects of the immunosuppressive medication, lower level of personal control, more use of emotion-focused coping, less disclosure about the transplant, and more stressful life events. The trajectories of persistent symptoms were associated with worse outcomes regarding medication adherence and health-related quality of life, but not with mortality. CONCLUSIONS: A significant subset of transplant recipients showed persistent symptoms of anxiety and depression from before to 2 years after transplantation. These results emphasize the importance of psychosocial care in the transplant population.

After liver transplantation, recipients often experience psychological problems that are influenced by demographic, personal, and transplant-related variables. However, because previous studies have mostly reported on psychological problems and their influencing factors in the first years after transplantation, less is known about their prevalence and influence in the long run. The aims of this study were to examine point-prevalence rates of symptoms of anxiety, depression, and posttraumatic stress (PTS) at different time periods after transplantation and to examine the transplant-related variables associated with these problems. A cross-sectional survey was performed among 373 liver transplant recipients who received transplants between 1979 and 2009 at our center. Five clinically relevant time periods were identified: 0.5 to <2 years, 2 to <5 years, 5 to <10 years, 10 to <15 years, and ≥15 years after transplantation. The response rate was 75% (n=281). Overall, 33.4% of the respondents experienced clinically relevant symptom levels of anxiety (28.7%), depression (16.5%), or PTS (10.0%). Symptoms of anxiety and depression were more prevalent in the first 2 years and in the long term after transplantation. PTS symptoms were more prevalent in the first 5 years after transplantation. However, the prevalence rates did not differ significantly between time periods. Viral hepatitis and the number of side effects of the immunosuppressive (IS) medication were found to be associated with all psychological problems. Alcoholic liver disease was associated with anxiety and depression in the short term after transplantation. In conclusion, a significant subset of transplant recipients experience psychological problems, both shortly after transplantation and in the long run. These problems are often associated with side effects from the IS medication. Therefore, the monitoring of psychological problems, the offering of psychological counseling, and the management of the medication's side effects should be part of the routine care of transplant recipients.

At the time of the organ offer for transplantation, donor-related risks such as disease transmission and graft failure are weighed against the patient's risk of remaining on the waiting list. The patient's commonly inactive role in decision making and the timing and extent of donor-specific risk information have been discussed in the medical literature. This is the first study revealing the opinions of liver patients on these issues. Forty patients listed for liver transplantation and 179 liver transplant patients participated in an anonymous questionnaire-based survey. The majority of the patients wanted to be informed about donor-related risks (59.8%-74.8%). The preferred timing for being informed about donor-related risks was the time of the organ offer for 53.3% of the patients. Among these patients, 79.8% wished to be involved in making the decision to accept or not accept a liver for transplantation, 10.6% wished to make the final decision alone, and only 9.6% did not want to be involved in the decision-making process. Implementing this knowledge through the standardization of the content, the manner of transfer, and the amount of information that we provide to our patients will improve opportunities for shared decision making at different time points during the transplant allocation process. This will enable us to provide the same opportunities and care to every patient on the waiting list.

AIMS AND OBJECTIVES: To compare a functioning assessment based on the International Classification of Functioning, Disability and Health (ICF) with a conventional medical assessment, in terms of their respective consequences for health professionals' clinical decision-making and the fit with patient's own perspective of health. BACKGROUND: In chronic diseases, pathogenic-oriented health care falls short in generating all the information required for determining healthcare provision to improve health. A broader, so-called salutogenic approach, by using the ICF, focusing on how to stay healthy, rather than on what causes diseases, seems more appropriate. DESIGN: A cross-sectional comparative study using data from a randomised controlled trial. METHODS: Data about patient problems and professional healthcare activities were collected from a total of 81 patients with severe multiple sclerosis who were randomly assigned to one of two groups: the ICF group, assessed with a functioning assessment (n = 43), and the medical group, assessed with a conventional medical assessment (n = 38). Data were analysed statistically using descriptive and inferential statistics. RESULTS: A functioning assessment resulted in the registration of significantly more patient problems in the health components 'participation' and 'environmental factors', as well as significantly more professional healthcare activities befitting these components. The ICF group had a significant positive correlation between registered problems by health professionals and patients' self-reported problems, whereas the medical group had several negative correlations. CONCLUSION: A functioning assessment resulted in a care plan that not only was broader and more complete but also reflected the patients' self-reported problems more closely than a medical assessment, without a loss of focus on medical problems. RELEVANCE TO CLINICAL PRACTICE: This study has shown that some health problems remain unnoticed by a medical assessment alone, which is especially important for the chronically ill. A functioning assessment provides a strong foundation for identifying all relevant information related to health.

INTRODUCTION: Patients with end-stage liver disease awaiting orthotopic liver transplantation (OLT) are generally classified as frail due to disease-related malnutrition and a progressive decline in musculoskeletal and aerobic fitness, which is associated with poor pre-OLT, peri-OLT and post-OLT outcomes. However, frailty in these patients may be reversable with adequate exercise and nutritional interventions. METHODS AND ANALYSIS: Non-randomised clinical trial evaluating the effect of a home-based bimodal lifestyle programme in unfit patients with a preoperative oxygen uptake (VO2) at the ventilatory anaerobic threshold ≤13 mL/kg/min and/or VO2 at peak exercise ≤18 mL/kg/min listed for OLT at the University Medical Center Groningen (UMCG). The programme is patient tailored and comprises high-intensity interval and endurance training, and functional exercises three times per week, combined with nutritional support. Patients will go through two training periods, each lasting 6 weeks.The primary outcome of this study is the impact of the programme on patients' aerobic fitness after the first study period. Secondary outcomes include aerobic capacity after the second study period, changes in sarcopenia, anthropometry, functional mobility, perceived quality of life and fatigue, incidence of hepatic encephalopathy and microbiome composition. Moreover, number and reasons of intercurrent hospitalisations during the study and postoperative outcomes up to 12 months post OLT will be recorded. Finally, feasibility of the programme will be assessed by monitoring the participation rate and reasons for non-participation, number and severity of adverse events, and dropout rate and reasons for dropout. ETHICS AND DISSEMINATION: This study was approved by the Medical Research Ethics Committee of the UMCG (registration number NL83612.042.23, August 2023) and is registered in the Clinicaltrials.gov register (NCT05853484). Good Clinical Practice guidelines and the principles of the Declaration of Helsinki will be applied. Results of this study will be submitted for presentation at (inter)national congresses and publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT05853484.

Little is known about the extent to which transplant recipients face emotional problems with the receipt of a transplanted organ. The Transplant Effects Questionnaire (TxEQ) enables the quantification of these problems. This study evaluates the psychometric properties of the Dutch translation of the TxEQ (TxEQ-NL) in a group of liver transplant recipients. Confirmatory factor analyses of the TxEQ-NL revealed an adequate fit with the original version. However, four items showed factor loadings <.40. Internal consistency was acceptable (.66-.79). The small correlations between the TxEQ-NL and generic measures of psychological functioning indicated that the constructs measured are related but distinguishable. Therefore, the TxEQ-NL adds a new dimension to the measurement of psychological functioning of transplant recipients.

Purpose of Review: To highlight the importance of biological age in the context of prehabilitation and to present relevant research regarding prehabilitation prior to solid organ transplantation. Recent Findings: Studies on the effect of prehabilitation have been performed in kidney-, lung-, liver-, and heart transplant patient populations. Prior to kidney transplantation, exercise interventions have been shown to improve cardiopulmonary- and physical fitness and result in a decreased length of hospital stay postoperatively. Among lung transplant candidates, various methods of prehabilitation have been studied including home-based, outpatient and in-patient programs, consisting of physical training, psychological support, education, and nutritional interventions. Overall, prehabilitation seems to improve or maintain quality of life and exercise capacity in this patient population. Patients undergoing liver transplantation seem to benefit from prehabilitation as well. Not only does it seem safe and feasible, but significant improvements in aerobic and functional capacity have also been found. Regarding heart transplant candidates, both inpatient and outpatient, supervised prehabilitation programs show promising results with improvements in exercise capacities and quality of life. Summary: Prehabilitation is an effective and safe intervention for improving functional outcomes of solid organ transplant patients. Future studies should evaluate whether prehabilitation translates into improved pre- and post-transplant clinical outcomes.
RESUMEN
OBJECTIVE: To develop a self-management instrument for organ transplant recipients that incorporates self-regulations skills and to determine its measurement properties. METHODS: The instrument includes concepts from social cognitive models: problem awareness, attitude, self-efficacy, motivation, social support, goal setting, goal pursuit, skills and goal affect. The measurement properties were evaluated based on the COSMIN guidelines. Face and content validity were determined through patient assessment, Three-Step Test-Interview and expert assessment using the Content Validity Index. Structural validity and reliability were tested using exploratory factor analysis and Cronbach's alpha. Construct validity was tested by comparing subscales with the Health Education Impact Questionnaire (heiQ). RESULTS: After face and content validity assessment 47 items were entered into the exploratory factor analysis. The analysis showed two meaningful factors, with internal consistency of 0.90 and 0.89. Spearman correlations between the subscales and heiQ were moderate (0.55; 0.46). The final version consists of 21 items, divided into two scales: 'Setbacks' and 'Successes'. CONCLUSIONS: The Self-regulation skills instrument in transplantation (SSIt) is a valid and reliable instrument to asses necessary skills for self-management after transplantation and may be useful for other patients as well. PRACTICE IMPLICATIONS: Insight into self-regulation competencies can help healthcare professionals to tailor self-management support.

INTRODUCTION: Kidney transplant candidates (KTCs) need to be in optimal physical and psychological condition prior to surgery. However, KTCs often experience compromised functional capacity which can be characterised as frailty. Prehabilitation, the enhancement of a person's functional capacity, may be an effective intervention to improve the health status of KTCs. The PREhabilitation of CAndidates for REnal Transplantation (PreCareTx) study aims to examine the effectiveness of a multimodal prehabilitation programme on the health status of KTCs, and to explore the potential of implementation of prehabilitation in daily clinical practice. METHODS AND ANALYSIS: This study uses a single centre, effectiveness-implementation hybrid type I study design, comprised of a randomised controlled trial and a mixed-methods study. Adult patients who are currently on the transplant waiting list or are waitlisted during the study period, at a university medical centre in The Netherlands, will be randomly assigned to either prehabilitation (n=64) or care as usual (n=64) groups. The prehabilitation group will undergo a 12-week home-based, tailored prehabilitation programme consisting of physical and/or nutritional and/or psychosocial interventions depending on the participant's deficits. This programme will be followed by a 12-week maintenance programme in order to enhance the incorporation of the interventions into daily life. The primary endpoint of this study is a change in frailty status as a proxy for health status. Secondary endpoints include changes in physical fitness, nutritional status, psychological well-being, quality of life and clinical outcomes. Tertiary endpoints include the safety, feasibility and acceptability of the prehabilitation programme, and the barriers and facilitators for further implementation. ETHICS AND DISSEMINATION: Medical ethical approval was granted by the Medical Ethics Committee Groningen, Netherlands (M22.421). Written informed consent will be obtained from all participants. The results will be disseminated at international conferences and in peer-reviewed journals. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov, NCT05489432.

Impaired interplay between sensory and motor function may be an important, often overlooked cause of the decreased daily functioning and impaired health-related quality of life (HRQoL) of kidney transplant recipients (KTR). We assessed this interplay using a hand dexterity test, and investigated its potential associations with daily functioning and HRQoL among KTR enrolled at the TransplantLines Biobank and Cohort Study. A total of 309 KTR (58% male, mean age 56 ± 13 years) at median 4 [IQR: 1-11] years after transplantation were included. Impaired hand dexterity, as defined by a test performance slower than the 95th percentile of an age- and sex-specific reference population, was observed in 71 (23%) KTR. Worse hand dexterity was independently associated with worse performance on almost all measures of physical capacity, activities of daily living and societal participation. Finally, hand dexterity was independently associated with physical HRQoL (standardized beta - 0.22, 95%CI - 0.34 to - 0.09, P < 0.001). In conclusion, impaired interplay between sensory and motor function, as assessed by hand dexterity, is prevalent among KTR. In addition, poor hand dexterity was associated with impaired daily functioning and limited physical HRQoL. Impaired interplay between sensory and motor function may be therefore an important, hitherto overlooked, phenomenon in KTR.

BACKGROUND AND OBJECTIVES: To date, employment figures of kidney transplant recipients in Europe are inconsistent. Additionally, little is known about work functioning of employed kidney transplant recipients and work functioning trajectories before and after transplantation. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Data from the ongoing TransplantLines Biobank and Cohort study and from community-dwelling employed adults were used. Health-related work functioning of kidney transplant recipients was assessed with the Work Role Functioning Questionnaire 2.0 and compared with potential kidney donors and community-dwelling employed adults. RESULTS: We included 668 kidney transplant recipients of working age (59% men, age 51±11 years) at median 3 (interquartile range, 2-10) years after transplantation, 246 potential kidney donors of working age (43% men, age 53±9 years), and 553 community-dwelling employed adults (70% men, age 45±11 years). The proportion of employed kidney transplant recipients was lower compared with potential kidney donors (56% versus 79%). If employed, the work functioning score of kidney transplant recipients was slightly lower compared with employed potential kidney donors yet higher compared with community-dwelling employed adults (medians 91 [interquartile range, 76-98], 94 [interquartile range, 85-99], and 88 [interquartile range, 79-95], respectively). Backward linear regression analyses revealed that lower educational level, having a kidney from a deceased donor, presence of tingling or numbness of hands or feet, presence of concentration/memory problems, presence of anxiety, and presence of severe fatigue were independently associated with lower work functioning among kidney transplant recipients. Additional subgroup analyses showed that work functioning scores were lower before transplantation than at 12 months after transplantation (83 [interquartile range, 66-93] versus 92 [interquartile range, 88-98], respectively; P=0.002). CONCLUSIONS: Stable employed kidney transplant recipients report to function well at work. In addition, this study shows that self-reported work functioning is higher after successful kidney transplantation compared with before transplantation.

Frailty is a multidimensional condition and is the result of the body's age-associated decline in physical, cognitive, physiological, and immune reserves. The aim of this systematic review is to assess the quality of evidence of the included studies, determine the prevalence of frailty among kidney transplant candidates, and evaluate the relationship between frailty and associated patient characteristics and outcomes after kidney transplantation. METHODS: A systematic search was performed for relevant literature on frailty and kidney transplantation. This was followed by a meta-analysis for patient characteristics and outcomes reported by a minimum of 2 studies including mean age, gender, mean body mass index, type of kidney transplantation, dialysis, previous kidney transplantation, comorbidities, hypertension, race, preemptive kidney transplantation, delayed graft function, and length of stay. RESULTS: A total of 18 studies were included in the systematic review and 14 of those studies were suitable for meta-analysis. The overall pooled prevalence of frailty before transplantation was estimated at 17.1% (95% confidence interval [CI], 15.4-18.7). Frailty was significantly associated with higher age (mean difference, 3.6; 95% CI, 1.4-5.9), lower rate of preemptive transplantation (relative risk, 0.60; 95% CI, 0.4-0.9), longer duration of delayed graft function (relative risk, 1.80; 95% CI, 1.1-3.0), and length of stay longer than 2 wk (odds ratio, 1.64; 95% CI, 1.2-2.3). CONCLUSIONS: One in 6 kidney transplant recipients is frail before transplantation. The presence of frailty is associated with lower rates of preemptive transplantation, older recipient age, higher rates of delayed graft function, and longer length of stay. Future research is required to explore the association of frailty with other adverse outcomes after kidney transplantation and the effects of intervention programs to improve the different frailty domains.
