Brain and spine malformations and neurodevelopmental disorders in a cohort of children with CAKUT. Pediatr Nephrol 2024; 39:2115-2129. [PMID: 38376554 DOI: 10.1007/s00467-024-06289-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/18/2023] [Revised: 12/12/2023] [Accepted: 01/03/2024] [Indexed: 02/21/2024]
Abstract
BACKGROUND Congenital anomalies of the kidney and urinary tract (CAKUT) represent 20-30% of all birth defects and are often associated with extra-renal malformations. We investigated the frequency of brain/spine malformations and neurological features in children with CAKUT. METHODS We reviewed the clinico-radiological and genetic data of 199 out of 1,165 children with CAKUT evaluated from 2006 to 2023 (99 males, mean age at MRI 6.4 years) who underwent brain and/or spine MRI. Patients were grouped according to the type of CAKUT (CAKUT-K involving the kidney and CAKUT-H involving the inferior urinary tract). Group comparisons were performed using χ2 and Fisher exact tests. RESULTS Brain/spine malformations were observed in 101/199 subjects (50.7%), 8.6% (101/1165) of our CAKUT population, including midbrain-hindbrain anomalies (40/158, 25.3%), commissural malformations (36/158, 22.7%), malformation of cortical development (23/158, 14.5%), Chiari I anomaly (12/199, 6%), cranio-cervical junction malformations (12/199, 6%), vertebral defects (46/94, 48.9%), caudal regression syndrome (29/94, 30.8%), and other spinal dysraphisms (13/94, 13.8%). Brain/spine malformations were more frequent in the CAKUT-K group (62.4%, p < 0.001). Sixty-two subjects (62/199, 31.2%) had developmental delay/intellectual disability. Neurological examination was abnormal in 40/199 (20.1%). Seizures and/or electroencephalographic anomalies were reported in 28/199 (14%) and behavior problems in 19/199 subjects (9%). Developmental delay/intellectual disability was more frequent in kidney dysplasia (65.2%) and agenesis (40.7%) (p = 0.001). CONCLUSIONS We report a relative high frequency of brain/spine malformations and neurodevelopmental disorders in children with CAKUT who underwent MRI examinations in a tertiary referral center, widening the spectrum of anomalies associated with this condition.

The eTHINK Study: Cognitive and Behavioral Outcomes in Children with Hemophilia. J Pediatr 2024; 272:114089. [PMID: 38734133 DOI: 10.1016/j.jpeds.2024.114089] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/05/2024] [Revised: 04/12/2024] [Accepted: 05/05/2024] [Indexed: 05/13/2024]
Abstract
OBJECTIVE To assess cognitive, behavioral, and adaptive functions in children and young adults with hemophilia treated according to contemporary standards of care. STUDY DESIGN Evolving Treatment of Hemophilia's Impact on Neurodevelopment, Intelligence, and Other Cognitive Functions (eTHINK) is a US-based, prospective, cross-sectional, observational study (September 2018 through October 2019). Males (aged 1-21 years) with hemophilia A or B of any severity, with or without inhibitors, were eligible. Participants underwent neurologic examinations and age-appropriate neuropsychological assessments, including standardized tests/ratings scales of early development, cognition, emotional/behavioral adjustment, and adaptive skills. RESULTS Five hundred and fifty-one males with hemophilia A (n = 433) or B (n = 101) were enrolled. Performance on cognitive tests was largely comparable with that of age-matched US population norms, although participants in certain age groups (4-5 and 10-21 years) performed worse on measures of attention and processing speed. Furthermore, adolescents and young adults and those with comorbid attention-deficit/hyperactivity disorder (ADHD; n = 64) reported more adaptive and executive function problems in daily life. Incidence of ADHD in adolescents (21%) was higher than expected in the general population. CONCLUSIONS In general, males with hemophilia demonstrated age-appropriate intellectual, behavioral, and adaptive development. However, specific patient/age groups showed poorer attention performance and concerns for executive and adaptive development. This study established a normative data set for monitoring neurodevelopment in individuals with hemophilia and highlight the importance of screening and intervention for challenges with cognitive and adaptive skills in this population.

Longitudinal changes of health-related quality of life in childhood chronic kidney disease. Pediatr Nephrol 2023; 38:4127-4136. [PMID: 37428223 PMCID: PMC10591962 DOI: 10.1007/s00467-023-06069-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/30/2023] [Revised: 06/12/2023] [Accepted: 06/20/2023] [Indexed: 07/11/2023]
Abstract
BACKGROUND Few longitudinal studies have evaluated the impact of chronic kidney disease (CKD) duration on health-related quality of life (HRQOL). The study's aim was to determine how HRQOL changes over time in childhood CKD. METHODS Study participants were children in the chronic kidney disease in children (CKiD) cohort who completed the pediatric quality of life inventory (PedsQL) on three or more occasions over the course of two or more years. Generalized gamma (GG) mixed-effects models were applied to assess the effect of CKD duration on HRQOL while controlling for selected covariates. RESULTS A total of 692 children (median age = 11.2) with a median of 8.3 years duration of CKD were evaluated. All subjects had a GFR greater than 15 ml/min/1.73 m2. GG models with child self-report PedsQL data indicated that longer CKD duration was associated with improved total HRQOL and the 4 domains of HRQOL. GG models with parent-proxy PedsQL data indicated that longer duration was associated with better emotional but worse school HRQOL. Increasing trajectories of child self-report HRQOL were observed in the majority of subjects, while parents less frequently reported increasing trajectories of HRQOL. There was no significant relationship between total HRQOL and time-varying GFR. CONCLUSIONS Longer duration of the disease is associated with improved HRQOL on child self-report scales; however, parent-proxy results were less likely to demonstrate any significant change over time. This divergence could be due to greater optimism and accommodation of CKD in children. Clinicians can use these data to better understand the needs of pediatric CKD patients. A higher resolution version of the Graphical abstract is available as Supplementary information.

Abstract
BACKGROUND Children with CKD are at risk for impaired neurocognitive functioning. We investigated metabolomic associations with neurocognition in children with CKD. METHODS We leveraged data from the Chronic Kidney Disease in Children (CKiD) study and the Neurocognitive Assessment and Magnetic Resonance Imaging Analysis of Children and Young Adults with Chronic Kidney Disease (NiCK) study. CKiD is a multi-institutional cohort that enrolled children aged 6 months to 16 years with eGFR 30-90 ml/min per 1.73 m 2 ( n =569). NiCK is a single-center cross-sectional study of participants aged 8-25 years with eGFR<90 ml/min per 1.73 m 2 ( n =60) and matched healthy controls ( n =67). Untargeted metabolomic quantification was performed on plasma (CKiD, 622 metabolites) and serum (NiCK, 825 metabolites) samples. Four neurocognitive domains were assessed: intelligence, attention regulation, working memory, and parent ratings of executive function. Repeat assessments were performed in CKiD at 2-year intervals. Linear regression and linear mixed-effects regression analyses adjusting for age, sex, delivery history, hypertension, proteinuria, CKD duration, and glomerular versus nonglomerular diagnosis were used to identify metabolites associated with neurocognitive z-scores. Analyses were performed with and without adjustment for eGFR. RESULTS There were multiple metabolite associations with neurocognition observed in at least two of the analytic samples (CKiD baseline, CKiD follow-up, and NiCK CKD). Most of these metabolites were significantly elevated in children with CKD compared with healthy controls in NiCK. Notable signals included associations with parental ratings of executive function: phenylacetylglutamine, indoleacetylglutamine, and trimethylamine N-oxide-and with intelligence: γ -glutamyl amino acids and aconitate. CONCLUSIONS Several metabolites were associated with neurocognitive dysfunction in pediatric CKD, implicating gut microbiome-derived substances, mitochondrial dysfunction, and altered energy metabolism, circulating toxins, and redox homeostasis.

Pediatr Transplant 2023; 27:e14505.

Abstract
BACKGROUND Pediatric chronic kidney disease (CKD) patients are at risk for cognitive deficits with worsening disease progression. Limited, existing cross-sectional studies suggest that cognitive deficits may improve following kidney transplantation. We sought to assess cognitive performance in relationship to kidney transplantation and kidney-specific medical variables in a sample of pediatric kidney transplant patients who provided cross-sectional and longitudinal observations. METHODS A retrospective chart review was conducted in patients who completed pre- and/or post-transplant neurocognitive testing at the University of Iowa from 2015-2021. Cognitive outcomes were investigated with developmentally appropriate, standardized measures. Mixed linear models estimated the impact of transplant status on cognitive function (z-scores). Subsequent post-hoc t-tests on change scores were limited to patients who had provided pre- and post-transplant assessments. RESULTS Thirty eight patients underwent cognitive assessments: 10 had both pre- and post-transplant cognitive assessments, 11 had pre-transplant assessments only, and 17 had post-transplant data only. Post-transplant status was associated with significantly lower full-scale IQ and slower processing speed compared to pre-transplant status (estimate = -0.32, 95% confidence interval [CI] = -0.52: -0.12; estimate = -0.86, CI = -1.17: -0.55, respectively). Post-hoc analyses confirmed results from the mixed models (FSIQ change score = -0.34, 95% CI = -0.56: -0.12; processing speed change score = -0.98, CI = -1.28: -0.68). Finally, being ≥80 months old at transplant was associated with substantially lower FSIQ compared to being <80 months (estimate = -1.25, 95% CI = -1.94: -0.56). CONCLUSIONS Our results highlight the importance of monitoring cognitive function following pediatric kidney transplant and identify older transplant age as a risk factor for cognitive deficits.

Abstract
Background: This study investigates the effect of chronic kidney disease (CKD) stage on fatigue and health-related quality of life (HRQoL) in the pediatric population. Material and Methods: The PedsQL (Pediatric Quality of Life Inventory) Multidimensional Fatigue Scale (subcategories: general, sleep/rest, and cognitive fatigue) and HRQoL Generic Core Scales (subcategories: physical, emotional, social, and school functioning) questionnaires were completed by 30 patients aged from 7 to 18 years old with CKD stage 2−4, CKD stage 5 on dialysis (CKD 5D), and kidney transplantation (KTx), as well as their parents. Results: Both low “Total Fatigue” and “Total HRQoL” scores were reported in 16.7% of patients. “Sleep/Rest Fatigue”, “Emotional Functioning”, and “School functioning” were the lowest scored subcategories. CKD 5D/KTx patients presented lower “Sleep/Rest Fatigue” (p = 0.022) and, more frequently, low “School Functioning” scores (p = 0.029). The “Total HRQoL” score was correlated to the “Total Fatigue” score (rs = 0.625, p < 0.001). A low “Sleep/Rest Fatigue” score was associated with low “Physical Functioning”, “School Functioning”, and “Total HRQoL” scores (p = 0.016, p = 0.001, and p = 0.047 respectively). Parents’ HRQoL score was lower than patients’ score on “Physical Functioning” (p = 0.040) and “School Functioning” subcategories (p = 0.045). Conclusions: Fatigue and disturbed HRQoL are mostly observed in CKD 5D and KTx pediatric patients, and are associated with sleep disorders and school dysfunction. Fatigue affects HRQoL, which is perceived as more deteriorated by the patients’ parents.

Abstract
Health care transition (HCT) from pediatric to adult-focused services is a longitudinal process driven by the collaboration and interactions of adolescent/young adult patients, their families, providers, health care agencies, and environment. Health care providers in both pediatric and adult-focused settings must collaborate, as patients' health self-management skills are acquired in the mid-20s, after they have transferred to adult-focused care. Our manuscript discusses the individual and family support systems as they relate to adolescents and young adults with chronic or end-stage kidney disease. In the individual domain, we discuss demographic/socioeconomic characteristics, disease complexity/course, cognitive capabilities, and self-management/self-advocacy. In the family domain, we discuss family composition/culture factors, family function, parenting style, and family unit factors. We provide a section dedicated to patients with cognitive and developmental disability. Furthermore, we discuss barriers for HCT preparation and offer solutions as well as activities for HCT preparation.

Abstract
The Chronic Kidney Disease in Children (CKiD) prospective cohort study was designed to address the neurocognitive, growth, cardiovascular, and disease progression of children and adolescents with mild to moderate CKD. The study has had continuous funding from NIDDK for 17 years and has contributed significant advances in pediatric CKD. The goals of this educational review are threefold: (1) to provide an overview of the neurocognitive and psychosocial studies from CKiD to date; (2) to provide best practice recommendations for those working with the neurocognitive and psychosocial aspects of pediatric CKD based on CKiD findings; and (3) to help chart future goals and directives for both research and clinical practice. This collection of 22 empirical studies has produced a number of key findings for children and adolescents with mild to moderate CKD. While various studies suggest a relatively positive presentation for this population as a whole, without evidence of significant impairment or deterioration, findings do indicate the presence of neurocognitive dysfunction, emotional-behavioral difficulties, and lower quality of life for many children with CKD. These findings support the promotion of best practices that are accompanied by additional future clinical and research initiatives with this patient population.

Abstract
OBJECTIVE To investigate the associations between neurocognition and white matter integrity in children with chronic kidney disease (CKD). STUDY DESIGN This cross-sectional study included 17 boys (age 6-16 years) with a diagnosis of mild to moderate (stages 1-3, nondialysis/nontransplant) CKD because of congenital anomalies of the kidney and urinary tract and 20 typically developing community controls. Participants underwent 3T neuroimaging and diffusion-weighted magnetic resonance imaging to assess white matter fractional anisotropy. Multivariable linear regression models were used to evaluate the impact of each group (controls vs CKD) on white matter fractional anisotropy, adjusting for age. Associations between white matter fractional anisotropy and neurocognitive abilities within the CKD group were also evaluated using regression models that were adjusted for age. The false discovery rate was used to account for multiple comparisons; wherein false discovery values <0.10 were considered significant. RESULTS Global white matter fractional anisotropy was reduced in patients with CKD relative to controls (standardized estimate = -0.38, 95% CI -0.69:-0.07), driven by reductions within the body of the corpus callosum (standardized estimate = -0.44, 95% CI -0.75:-0.13), cerebral peduncle (SE = -0.37, 95% CI -0.67:-0.07), cingulum (hippocampus) (standardized estimate = -0.45, 95% CI -0.75:-0.14), and posterior limb of the internal capsule (standardized estimate = -0.46, 95% CI -0.76:-0.15). Medical variables and neurocognitive abilities were not significantly associated with white matter fractional anisotropy. CONCLUSIONS White matter development is vulnerable in children with CKD because of congenital causes, even prior to the need for dialysis or transplantation.

Abstract
Chronic kidney disease (CKD) affects more than 37 million American adults. Adult-onset CKD is typically attributed to acquired comorbidities such as aging, type II diabetes, and cardiovascular disease. Conversely, congenital abnormalities of the kidney and urinary tract are the most common cause of CKD in children. Both adult and pediatric patients with CKD are at risk for neurocognitive dysfunction, particularly in the domain of executive function. The exact mechanism for neurocognitive dysfunction in CKD is not known; however, it is conceivable that the multisystemic effects of CKD—including hypertension, acidosis, anemia, proteinuria, and uremic milieu—exert a detrimental effect on the brain. Quantitative neuroimaging modalities, such as magnetic resonance imaging (MRI), provide a non-invasive way to understand the neurobiological underpinnings of cognitive dysfunction in CKD. Adult patients with CKD show differences in brain structure; however, much less is known about the impact of CKD on neurodevelopment in pediatric patients. Herein, this review will summarize current evidence of the impact of CKD on brain structure and function and will identify the critical areas for future research that are needed to better understand the modifiable risk factors for abnormal brain structure and function across both pediatric and adult CKD populations.

Abstract
BACKGROUND Chronic kidney disease (CKD) is associated with cognitive dysfunction. Cognitive function in children with CKD residing in developing countries has not been previously reported. METHODS This cross-sectional study included children aged 6-18 years with CKD stages 2-5D and kidney transplant. Cognitive function was assessed by WISC-V for children from 6-16 years of age. In adolescents 17-18 years of age, WAIS-III was used. Factors associated with cognitive dysfunction were identified using multivariable regression analysis. RESULTS Thirty-seven children with median age 13.9 (11.3-15.7) years were recruited. The median full-scale intelligence quotient (FSIQ) was 83.0 (71.0-95.0). Below-average cognitive function (FSIQ <90) was identified in 24 children (64.8%), 24.3% of whom had cognitive impairment (FSIQ <70). Most children (94.6%) scored lower than average on at least 1 cognitive domain. Kidney replacement therapy (p = 0.03) and low family income (p = 0.02) were associated with below-average cognitive function in multivariable logistic regression analysis. Children who left school and low family income were significantly associated with cognitive function. The FSIQ of children who had left school was 12.94 points lower than the educated group (p = 0.046). In addition, every 10,000 Thai Baht (approximately 330 United States dollars) increase in family income correlated with 1.58 increase in FSIQ (p = 0.047). CONCLUSION Cognitive dysfunction was commonly found in children with CKD. Socioeconomic factors, particularly school attendance and family income, were associated with cognitive dysfunction. Cognitive evaluation is suggested for children with CKD who have socioeconomic risk factors. "A higher resolution version of the Graphical abstract is available as Supplementary information."

Abstract
An increasing amount of literature has indicated that chronic kidney disease (CKD) is associated with cognitive deficits that increase with worsening disease severity. Although abnormalities in brain structure have been widely documented, few studies to date have examined the functioning of brain areas associated with the specific cognitive domains affected by CKD (namely, attention and executive functions). Furthermore, few studies have examined functional connectivity among CKD youth who are relatively early in the course of the disease. The present study used functional magnetic resonance imaging to examine the resting state connectivity in 67 youth with CKD (mean age, 17 y) and 58 age-matched healthy controls. Using seed-based multiple regression, decreased connectivity was observed within the anterior cingulate portion of the default mode network. In addition, decreased connectivity within the dorsolateral prefrontal cortex, paracingulate gyrus, and frontal pole were correlated significantly with disease severity. These data indicate that connectivity deficits in circuits implementing attentional processes may represent an early marker for cognitive decline in CKD.

Abstract
Pediatric chronic kidney disease (CKD) is associated with deficits in neurocognitive functioning, ranging from mild to severe, and correlated with the severity of kidney disease. Clinical variables that are associated with neurocognitive deficits include lower kidney function, hypertension, proteinuria, and metabolic acidosis. Commonly reported neurocognitive difficulties include academic underachievement and deficits in attention regulation and executive function as well as somewhat lower intellectual abilities compared with peer and normative data. Although often mild, these neurocognitive deficits may have broad implications for quality of life and likely contribute to both poorer high school graduation rates and long-term underemployment in the adult CKD population. The presence of neurocognitive deficits in predialytic CKD has been well characterized, but further longitudinal research is warranted to describe cognitive changes as children progress from early stage CKD to kidney replacement therapy. Such studies should include both cognitive and neuroimaging evaluations to better inform the impact of CKD progression on neurocognitive outcomes.

Abstract
BACKGROUND Patients' loss to follow-up (LFU) has significant impacts on outcomes and is a barrier to improving care, especially in adolescent and young adult (AYA) renal transplant recipients. There is limited information regarding the relationship between transfer of care from pediatric to adult transplant centers, age, and LFU among AYA renal transplant recipients. METHODS We studied 16 386 individuals aged 10-29 years who received kidney transplants between January 1, 2005 and December 31, 2015 using the Scientific Registry of Transplant Recipients. The primary outcome was LFU, which was defined as >1 year without follow-up in a transplant clinic/program. Death or graft failure within a year of the last follow-up was not classified as LFU. We performed a retrospective cohort study describing LFU using Pearson's chi-square tests. Multivariable logistic regression was used to estimate the change in likelihood of LFU associated with recipient characteristics and institution transfer. RESULTS In total, 22.26% (n = 3647) of our study population met criteria for LFU. About 11.17% (n = 1830) transferred institutions during the study period. LFU occurred in 50.18% of recipients who transferred institutions. LFU peaked at the age of 20 years, with 7.4% of 20-year-olds having LFU. The odds of LFU among renal transplant recipients who transferred institutions were 3.36 times greater (95% confidence interval, 3.1-3.6) than the odds of LFU among those who did not transfer institutions. CONCLUSIONS LFU is a critical problem faced by AYA renal transplant recipients, and institution transfer is a significant risk factor for LFU. Additional studies investigating the interplay between age, institution transfer, and LFU in the AYA population are still needed.

Abstract
BACKGROUND Chronic kidney disease (CKD) has a negative impact on growth and development in children and is a risk factor for neurocognitive impairment; however, there is limited research on the cognitive function of children and adolescents with CKD. This study therefore aimed to investigate the mean intelligence and risk factors for low intelligence in children and adolescents with CKD. METHODS Eighty-one patients with CKD under 18 years old were included in the KoreaN cohort study for Outcomes in patients With Pediatric Chronic Kidney Disease (KNOW-Ped CKD). Participants completed either the Wechsler Intelligence Scale for Children (6-16 years), or Wechsler Adult Intelligence Scale (> 16 years). RESULTS The mean full-scale intelligence quotient (IQ) was 91 ± 19; 24.7% of participants scored a full-scale IQ below 80. Participants with a short stature (height Z scores < -1.88), failure to thrive (weight Z scores < -1.65), more severe CKD stage (≥ IIIb), longer duration of CKD (≥ 5 years), and those who were Medicare or Medicaid beneficiaries, had significantly lower mean full-scale IQs. CONCLUSION On linear regression analysis, the association between the full-scale IQ, and longer duration of CKD and growth failure, remained significant after controlling for demographic and clinical variables. It is therefore necessary to investigate cognitive impairment in pediatric patients with CKD who exhibit growth failure or for a longer postmorbid period. It is believed that early interventions, such as kidney transplantation, will have a positive effect on IQ in children with CKD, as the disease negatively affects IQ due to poor glomerular filtration rate over time.

Abstract
The 2020 Kidney Disease: Improving Global Outcomes (KDIGO) Clinical Practice Guideline on the Evaluation and Management of Candidates for Kidney Transplantation is intended to assist health care professionals worldwide who evaluate and manage potential candidates for deceased or living donor kidney transplantation. This guideline addresses general candidacy issues such as access to transplantation, patient demographic and health status factors, and immunological and psychosocial assessment. The roles of various risk factors and comorbid conditions governing an individual's suitability for transplantation such as adherence, tobacco use, diabetes, obesity, perioperative issues, causes of kidney failure, infections, malignancy, pulmonary disease, cardiac and peripheral arterial disease, neurologic disease, gastrointestinal and liver disease, hematologic disease, and bone and mineral disorder are also addressed. This guideline provides recommendations for evaluation of individual aspects of a candidate's profile such that each risk factor and comorbidity are considered separately. The goal is to assist the clinical team to assimilate all data relevant to an individual, consider this within their local health context, and make an overall judgment on candidacy for transplantation. The guideline development process followed the Grades of Recommendation Assessment, Development, and Evaluation (GRADE) approach. Guideline recommendations are primarily based on systematic reviews of relevant studies and our assessment of the quality of that evidence, and the strengths of recommendations are provided. Limitations of the evidence are discussed with differences from previous guidelines noted and suggestions for future research are also provided.

Abstract
Research demonstrates that psychological factors are important for positive transplant outcomes, though there is little literature that synthesizes these factors in a comprehensive model among pediatric kidney transplant patients. This review analyzes psychological and psychosocial factors related to medical outcomes and overall well-being post-transplant by utilizing the PPPHM and referencing the existing literature on risk and resilience. Pediatric kidney transplant recipients are more susceptible to mental health concerns such as depression, anxiety, and ADHD, as well as developmental and neurocognitive delays, compared to healthy peers. Complex medical care and psychosocial needs for patients have implications for family functioning, parental and sibling mental health, and youth readiness to transition to adult care. It is important to carefully monitor patient functioning with empirically validated tools and to intervene in a multidisciplinary setting as early as possible to identify patients at risk and reduce potential negative impact. Psychologists are uniquely trained to assess and address these issues and are a valuable component of multidisciplinary, culturally competent care. While research in this expansive field is improving, more data are needed to establish gold standard approaches to mental health and psychosocial care in this population.

Abstract
BACKGROUND The impact of pediatric chronic kidney disease (pCKD) on the brain remains poorly defined. The objective of this study was to compare brain morphometry between children with early-stage pCKD and typically developing peers using structural magnetic resonance imaging (MRI). METHODS The sample age range was 6-16 years. A total of 18 children with a diagnosis of pCKD (CKD stages 1-3) due to congenital anomalies of the kidney and urinary tract and 24 typically developing peers were included. Volumetric data from MRI and neurocognitive testing were compared using linear models including pCKD status, age, maternal education level, and socioeconomic status. RESULTS Cerebellar gray matter volume was significantly smaller in pCKD, t(38) = -2.71, p = 0.01. In contrast, cerebral gray matter volume was increased in pCKD, t(38) = 2.08, p = 0.04. Reduced cerebellum gray matter volume was associated with disease severity, operationalized as estimated glomerular filtration rate (eGFR), t(14) = 2.21, p = 0.04 and predicted lower verbal fluency scores in the pCKD sample. Enlarged cerebral gray matter in the pCKD sample predicted lower scores on mathematics assessment. CONCLUSIONS This study provides preliminary evidence for a morphometric underpinning to the cognitive deficits observed in pCKD. IMPACT The impact of pediatric chronic kidney disease (CKD) on the brain remains poorly defined, with no data linking brain morphometry and observed cognitive deficits noted in this population. We explored the relationship between brain morphometry (using structural magnetic resonance imaging), cognition, and markers of CKD. Cerebellar and cerebral gray matter volumes are different in early CKD. Volumetric decreases in cerebellar gray matter are predicted by lower eGFR, suggesting a link between disease and brain morphometry. Reduced cerebellar gray matter predicted lower verbal fluency for those with pCKD. Enlarged cerebral gray matter in the pCKD sample predicted lower mathematics performance.

Abstract
The recently published 2020 International Society for Peritoneal Dialysis (ISPD) practice recommendations regarding prescription of high-quality goal-directed peritoneal dialysis differ fundamentally from previous guidelines that focused on "adequacy" of dialysis. The new ISPD publication emphasizes the need for a person-centered approach with shared decision making between the individual performing peritoneal dialysis and the clinical care team while taking a broader view of the various issues faced by that individual. Cognizant of the lack of strong evidence for the recommendations made, they are labeled as "practice points" rather than being graded numerically. This commentary presents the views of a work group convened by the National Kidney Foundation's Kidney Disease Outcomes Quality Initiative (KDOQI) to assess these recommendations and assist clinical providers in the United States in interpreting and implementing them. This will require changes to the current clinical paradigm, including greater resource allocation to allow for enhanced services that provide a more holistic and person-centered assessment of the quality of dialysis delivered.

Abstract
BACKGROUND Examining executive functioning (EF) posttransplant has become increasingly prevalent, as EF deficits are associated with poor disease-related outcomes and psychosocial functioning. The purpose of the current meta-analysis was to compare overall and domain-specific EF between healthy youth and those with a kidney, heart, or liver transplant, and identify moderating variables related to EF differences between these 2 groups. METHODS A literature search of PsycINFO, Pubmed, and Medline was conducted for eligible articles published until January 2019. Twenty studies met eligibility criteria and were included in the present meta-analysis. RESULTS Results from the random-effects model indicated a significant standardized mean difference in overall EF skills with transplant recipients demonstrating worse EF (g = 0.40; 95% confidence interval [CI], 0.29-0.50) than healthy youth. Specifically, transplanted youth had worse working memory (g = 0.33; 95% CI, 0.01-0.66), processing speed (g = 0.41; 95% CI, 0.19-0.62), attentional control (g = 0.53; 95% CI, 0.33-0.73), and metacognitive skills (g = 0.36; 95% CI, 0.18-0.54). Assessment type and time since transplantation were not significant moderators. CONCLUSIONS Pediatric solid organ transplant recipients demonstrate worse overall EF skills and deficits in working memory, processing speed, attentional control, and metacognitive skills. Many children who have undergone solid organ transplantation will require additional support in medical and academic settings because of deficits in various EF domains.

Abstract
To investigate the correlation between chronic kidney disease (CKD) and the development of neurological disease among pediatric patients in Saudi Arabia. The present retrospective study recruited patients admitted to King Abdulaziz University Hospital during 2018. We reviewed electronic records to collect data on essential demographics including age, gender, and nationality; history of prior CNS disease or related symptoms; results of neurological physical examination; and findings of radiological investigations such as abdominal ultrasound, dimercaptosuccinic acid scan, micturating cystourethrogram, diethylene triamine pentaacetic acid scan, brain computed tomography, and magnetic resonance imaging. The most commonly diagnosed renal pathologies were neurogenic bladder and cystic kidney disease. The most common neurological manifestation was seizure disorder. Males were more frequently affected with neurological sequelae than females. The prevalence of neurological disorders was higher in patients over two years old. The most frequently observed stage of chronic kidney disease was stage 5. Most children who were affected with a neurological disorder required hemodialysis as part of their management plan. Patients with chronic kidney disease are at a high risk of neurocognitive defects. The type of management and renal diagnosis are significant factors that should be considered when anticipating central nervous system involvement in the case of chronic kidney disease.

Abstract
Rationale & Objective Chronic kidney disease (CKD) in children is associated with cognitive dysfunction that affects school performance and quality of life. The relationship between CKD-mineral and bone disorder and cognitive function in children is unknown. Study Design Observational study. Participants 702 children enrolled in the Chronic Kidney Disease in Children (CKiD) Study. Predictors Plasma fibroblast growth factor 23 (FGF-23), parathyroid hormone (PTH), calcium, phosphorus, 25 hydroxyvitamin D (25[OH]D), and 1,25 dihydroxyvitamin D (1,25[OH]2D). Outcomes Neurocognitive tests of intelligence, academic achievement, and executive functions. Analytical Approach Linear regression models to analyze the cross-sectional associations between log2FGF-23, 25(OH)D, 1,25(OH)2D, PTH, calcium, and phosphorus z scores and the cognitive test scores of interest after adjustment for demographics, blood pressure, proteinuria, and kidney function. Results At baseline, median age was 12 (95% CI, 8.3, 15.2) years and estimated glomerular filtration rate was 54 (40.5, 67.8) mL/min/1.73 m2. In fully adjusted analyses, 25(OH)D, 1,25(OH)2D, PTH, calcium, and phosphorus z scores did not associate with cognitive test scores. In fully adjusted analyses, log2FGF-23 was associated with abnormal test scores for attention regulation (P < 0.05); specifically, Conners' Continuous Performance Test II Errors of Omission (β = 2.3 [1.0, 3.6]), Variability (β=1.4 [0.4, -2.4]), and Hit Reaction Time (β = 1.3 [0.2, 2.4]). Children in the highest FGF-23 tertile group had 7% and 9% greater cognitive risk for Hit Reaction Time and Errors of Omission compared with those in the lowest tertile, respectively. In fully adjusted analyses, higher FGF-23 tertile was associated with increased cognitive risk (P < 0.05) for Errors of Omission (β = 0.4 [0.1, 0.7]) and Hit Reaction Time (β = 0.4 [0.1, 0.7]). Limitations The study does not assess the cumulative effects of FGF-23 excess on cognitive function over time. Within-population stratified analyses were not performed due to limited sample size. Conclusions In children with CKD, higher plasma FGF-23 level is associated with lower performance in targeted tests of executive function, specifically attention regulation, independent of glomerular filtration rate.

Abstract
Chronic kidney disease (CKD) is defined by the Kidney Disease and Outcome Quality Initiative as a child who has kidney damage lasting for at least three months with or without decreased glomerular filtration rate. Hemodialysis (HD) means removal of waste products and extra fluid directly from the blood when the kidneys do not work properly. Studies aimed at investigating neurocognitive impairment in children with CKD have identified a wide range of delays in cognitive development. The aim of this study was to assess the cognitive functions and adaptive behavior in children with end-stage renal disease (ESRD) on regular HD. This case-controlled study was conducted on 30 children suffering from ESRD who were on treatment at the Pediatric Nephrology Unit of Tanta University Hospital. Thirty apparently healthy children served as a control group, in the period from January 2017 to January 2018. All children were subjected to full history taking, careful physical and neurological examination, specific investigations including assessment of intelligence quotient (IQ) using Stanford Binet test 5th edition; assessment of adaptive behavior, assessment of executive functions by using Wisconsin Card Sorting Test; and continuous performance test. This study showed that mean values of IQ and the Vineland test were significantly lower among patients than controls. The study suggests that children with ESRD had lower IQ, adaptive behavior and executive functions than healthy control children.

Abstract
OBJECTIVE To determine postnatal neurodevelopmental (ND) outcomes for children with congenital lower urinary tract obstruction (LUTO) based on disease severity. METHODS Twenty male infants with LUTO were classified prenatally as Stage 1 (normal amniotic fluid and renal function; n = 5), Stage 2 (signs of obstruction with preserved renal function; n = 13), and Stage 3 (signs of severe renal damage; n = 2). ND status was assessed using the Developmental Profile-3 test in 5 developmental domains (physical, adaptive behavior, social-emotional, cognitive, and communication). Each domain was considered to be delayed if standard scores were 2 or more SD below the mean. ND outcomes were compared between cases with an expected normal renal function (LUTO Stage 1) and those with impaired renal function (LUTO Stages 2 and 3). Results from cases with Stage 2 were also compared to those from Stage 3. ORs were calculated to predict risk for adverse ND outcome for each domain considering prenatal and postnatal factors. RESULTS Gestational age (GA) at the diagnosis of LUTO was similar between both groups (Stage 1: 24.85 ± 7.87 vs. Stages 2 and 3: 21.4 ± 4.31 weeks; p = 0.24). Twelve of 15 cases with Stage 2 or 3 underwent vesicoamniotic shunt placement compared to none of Stage 1 fetuses (p < 0.01). No differences in GA at delivery were detected between the groups (37.9 ± 1.6 vs. 35.1 ± 3.6 weeks; p = 0.1). One of the infants in the Stage 2 and 3 groups received a kidney transplant during follow-up. One case (20%) from Stage 1 group required dialysis during the first 6 months of life, and 1 case from Stage 2 to 3 group required it during the first 6 months (p = 1.0), whereas 3 additional cases needed dialysis from 6 to 24 months (p = 0.6). Mean age at Developmental Profile 3 (DP-3) testing was 20.3 ± 12.3 months (Stage 1: 11.2 ± 8.6 vs. Stages 2 and 3: 23.4 ± 13.4 months; p = 0.07). Fifteen of the 20 patients (75%) had no ND delays. Of the 5 patients with ND delays, 4 received dialysis. No differences in ND outcomes between infants with LUTO Stage 1 and those with Stages 2 and 3 were detected except for a trend toward better physical development in Stage 1 (102.6 ± 11.6 vs. 80.7 ± 34.9; p = 0.05). Infants diagnosed with LUTO Stage 3 showed significantly lower adaptive scores than those diagnosed with Stage 2 (Stage 2: 101.9 ± 22.3 vs. Stage 3: 41.5 ± 30.4; p = 0.04) and a nonsignificant trend for lower results in physical (85.8 ± 33.0 vs. 47.5 ± 38.9; p = 0.1) and socio-emotional (94.7 ±17.9 vs. 73.5 ± 13.4; p = 0.1) domains. Infants who received dialysis showed 15-fold increased risk (95% CI 0.89-251) for delayed socio-emotional development (p = 0.06). Diagnosis of fetal renal failure increased the risk for delays in the adaptive domain 30-fold (95% CI 1.29-93.1; p = 0.03). Infants with abnormal renal function had 19 times (95% CI 1.95-292) increased risk for delays in the physical domain (p = 0.03). CONCLUSIONS While most patients with LUTO do not exhibiting ND delays, our results support the importance of ND monitoring, especially in severe forms of LUTO, as increased severity of this condition may be associated with poorer ND outcomes.

Abstract
Background Acute kidney injury (AKI) is a risk factor for neurocognitive impairment in severe malaria (SM), but the impact of AKI on long-term behavioral outcomes following SM is unknown. Methods We conducted a prospective study on behavioral outcomes of Ugandan children 1.5 to 12 years of age with two forms of severe malaria, cerebral malaria (CM, n = 226) or severe malarial anemia (SMA, n = 214), and healthy community children (CC, n = 173). AKI was defined as a 50% increase in creatinine from estimated baseline. Behavior and executive function were assessed at baseline and 6, 12, and 24 months later using the Child Behavior Checklist and Behavior Rating Inventory of Executive Function, respectively. Age-adjusted z-scores were computed for each domain based on CC scores. The association between AKI and behavioral outcomes was evaluated across all time points using linear mixed effect models, adjusting for sociodemographic variables and disease severity. Results AKI was present in 33.2% of children with CM or SMA at baseline. Children ≥6 years of age with CM or SMA who had AKI on admission had worse scores in socio-emotional function in externalizing behaviors (Beta (95% CI), 0.52 (0.20, 0.85), p = 0.001), global executive function (0.48 (0.15, 0.82), p = 0.005) and behavioral regulation (0.66 (0.32, 1.01), p = 0.0002) than children without AKI. There were no behavioral differences associated with AKI in children <6 years of age. Conclusions AKI is associated with long-term behavioral problems in children ≥6 years of age with CM or SMA, irrespective of age at study enrollment.

Abstract
BACKGROUND Kidneys from infectious risk donors (IRD) confer substantial survival benefit in adults, yet the benefit of IRD kidneys to pediatric candidates remains unclear in the context of high waitlist prioritization. METHODS Using 2010-2016 Scientific Registry of Transplant Recipients data, we studied 2417 pediatric candidates (age <18 y) who were offered an IRD kidney that was eventually used for transplantation. We followed candidates from the date of first IRD kidney offer until the date of death or censorship and used Cox regression to estimate mortality risk associated with IRD kidney acceptance versus decline, adjusting for age, sex, race, diagnosis, and dialysis time. RESULTS Over the study period, 2250 (93.1%) pediatric candidates declined and 286 (11.8%) accepted an IRD kidney offer; 119 (41.6%) of the 286 had previously declined a different IRD kidney. Cumulative survival among those who accepted versus declined the IRD kidney was 99.6% versus 99.4% and 96.3% versus 97.8% 1 and 6 years post decision, respectively (P = 0.1). Unlike the substantial survival benefit seen in adults (hazard ratio = 0.52), among pediatric candidates, we did not detect a survival benefit associated with accepting an IRD kidney (adjusted hazard ratio: 0.791.723.73, P = 0.2). However, those who declined IRD kidneys waited a median 9.6 months for a non-IRD kidney transplant (11.2 mo among those <6 y, 8.8 mo among those on dialysis). Kidney donor profile index (KDPI) of the eventually accepted non-IRD kidneys (median = 13, interquartile range = 6-23) was similar to KDPI of the declined IRD kidneys (median = 16, interquartile range = 9-28). CONCLUSIONS Unlike in adults, IRD kidneys conferred no survival benefit to pediatric candidates, although they did reduce waiting times. The decision to accept IRD kidneys should balance the advantage of faster transplantation against the risk of infectious transmission.

Abstract
BACKGROUND Environmental lead exposure is associated with cognitive impairment in healthy children, with deficits seen in intelligence quotient (IQ), attention, and behavior. Neurocognitive dysfunction is also a well-described complication among children with chronic kidney disease (CKD). The objective was to evaluate the association between blood lead levels (BLL) and performance on neurocognitive assessments in a cohort of children with CKD. METHODS Cross-sectional study of children with mild to moderate CKD from the Chronic Kidney Disease in Children (CKiD) multicenter prospective cohort study. The primary exposure was BLL. The primary outcome was performance on age-specific neurocognitive assessments evaluating IQ, executive functioning, attention, hyperactivity, and behavior. Multivariable linear regression was used to evaluate the association between BLL and neurocognitive performance, adjusted for key sociodemographic and clinical variables. RESULTS A total of 412 subjects were included with median age 15.4 years, median estimated GFR 39 mL/min/1.732, median BLL 1.2 mcg/dL, and median IQ score 99. In multivariable linear regression, higher BLL was associated with significantly lower IQ score (- 2.1 IQ points for every 1-mcg/dL increase in BLL, p = 0.029). Higher BLL was associated with worse scores on the Conners' Continuous Performance Test II Variability T-Score, a measure of inattention (+ 1.8 T-Score points for every 1-mcg/dL increase in BLL, p = 0.033). CONCLUSIONS Low-level lead exposure is associated with significantly lower IQ and more inattention in children with CKD, a population already at high risk for neurocognitive dysfunction. Universal screening for elevated BLL should be considered for all children with CKD at age 12-24 months.

Abstract
Parents of pediatric liver and kidney transplant recipients were surveyed regarding their current education plans (eg, Individualized Education Program, 504), satisfaction with these plans, and interest in educational support from the psychosocial transplant team. Survey results indicate high rates of IEP and 504 plans, academic and related services, and accommodations among this population. The majority of parents/guardians reported satisfaction with their child's current school plan and did not report need for additional transplant team support specific to school services on the survey measure. However, other information highlights the importance for pediatric transplant teams to consider other ways to support this population's educational needs.

Abstract
OBJECTIVE The objective of this study was to facilitate functional health literacy (FHL) with a modified "Teach Back" method. A computer-based program was developed for adolescent and young adult kidney transplant recipients (KTR) to knowledgeably answer questions about their medical condition, medications, and create a simple synopsis of their personal health record with the help of the heath care provider (HCP). METHODS In a pre-post quasi-experimental design, 16 patients received the computer intervention in which they navigated questionnaires and brief informational video clips. Knowledge scores were assessed at baseline and 3 months. The binomial sign test was used to evaluate change in knowledge and purpose of medications. RESULTS Mean age was 17.3 ± 2.4 years and 94% were non-Caucasian. Seven of 16 patients were academically below grade level. Twelve of 16 patients improved their overall knowledge (P = 0.0002) and purpose of medications (P = 0.0017). CONCLUSIONS A Modified "Teach Back" during clinic visits was associated with improvements in FHL. PRACTICE IMPLICATIONS This modified 'teach back' program has the potential to improve FHL which could contribute to long-term preservation of kidney transplants.

Renal Replacement Therapy in children with severe developmental disability: guiding questions for decision-making. Eur J Pediatr 2018; 177:1735-1743. [PMID: 30194525 DOI: 10.1007/s00431-018-3238-3] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/09/2018] [Revised: 08/20/2018] [Accepted: 08/29/2018] [Indexed: 10/28/2022]
Abstract
Whether to initiate or to withhold Renal Replacement Therapy (RRT) in children with severe developmental disability (DD) remains a topic of intense debate. The present study investigated the opinion of professionals on this difficult issue and proposed a checklist with guiding questions for decision-making. Clinicians affiliated to different organizations involved in pediatric nephrology worldwide were invited to respond to a web-based survey. This survey focused on the collection of demographic data of the respondents together with their opinion concerning the decision-making regarding RRT in a particular case and for children with severe DD in general. A total of 286 professionals responded to the survey. Sixty-six percent supported initiating RRT in the child of the case report, with pre-emptive transplantation being the preferred modality. Important arguments pro RRT initiation in children with severe DD in general were parental preference, decrease of suffering, and improvement of survival and quality of life. Important contraindications included low IQ, severe comorbidities, and inability of the patient to take medication or for the family to provide sufficient care.Conclusion: The present study presents an inventory on the opinions of health care professionals involved in RRT in children regarding the treatment of children with DD and assists in the decision-making process by identifying important medical and psychosocial arguments for initiating or withholding RRT in severe DD patients. What is Known: •Renal Replacement Therapy (RRT) in children with severe developmental disability (DD) is a topic of intense debate. •Previous studies on the opinion of professionals mainly focused on the use of IQ as an argument in the decision-making whether or not starting RRT. What is New: •The present study investigated the opinion of professionals with regard to considering initiation or withholding RRT in children with severe DD and identified medical and psychosocial arguments playing a role in the decision-making process. •Based on these arguments, a checklist with guiding questions for decision-making is proposed.

Abstract
BACKGROUND Chronic kidney disease (CKD) is a risk factor for vascular disease and stroke. The spectrum of brain injury and microstructural white matter abnormalities in children with CKD is largely unknown. METHODS Cross sectional study at two North American pediatric hospitals. A cohort of 49 children, 29 with CKD, including renal transplant (mean age 14.4 ± 2.9 years; range 9-18), and 20 healthy controls (mean age 13.7 ± 3.1 years; range 9-18) had their conventional brain magnetic resonance images (MRIs) reviewed by one neuroradiologist to determine the prevalence of brain injury. Fractional anisotropy (FA) maps calculated from diffusion tensor imaging (DTI) were generated to compare white matter microstructure in CKD compared to controls, using tract-based spatial statistics (TBSS). RESULTS Focal and multifocal white matter injury was seen on brain MRI in 6 children with CKD (21%). Relative to controls, CKD subjects showed reduced white matter fractional anisotropy and increased mean diffusivity and radial diffusivity in the anterior limb of the internal capsule, suggestive of abnormal myelination. CONCLUSION Cerebral white matter abnormalities, including white matter injury, are under-recognized in pediatric CKD patients. Brain imaging studies through progression of CKD are needed to determine the timing of white matter injury and any potentially modifiable risk factors.

A Randomized Trial of a Multicomponent Intervention to Promote Medication Adherence: The Teen Adherence in Kidney Transplant Effectiveness of Intervention Trial (TAKE-IT). Am J Kidney Dis 2018; 72:30-41. [PMID: 29602631 DOI: 10.1053/j.ajkd.2017.12.012] [Citation(s) in RCA: 88] [Impact Index Per Article: 14.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2017] [Accepted: 12/21/2017] [Indexed: 11/11/2022]
Abstract
BACKGROUND Poor adherence to immunosuppressive medications is a major cause of premature graft loss among children and young adults. Multicomponent interventions have shown promise but have not been fully evaluated. STUDY DESIGN Unblinded parallel-arm randomized trial to assess the efficacy of a clinic-based adherence-promoting intervention. SETTING & PARTICIPANTS Prevalent kidney transplant recipients 11 to 24 years of age and 3 or more months posttransplantation at 8 kidney transplantation centers in Canada and the United States (February 2012 to May 2016) were included. INTERVENTION Adherence was electronically monitored in all participants during a 3-month run-in, followed by a 12-month intervention. Participants assigned to the TAKE-IT intervention could choose to receive text message, e-mail, and/or visual cue dose reminders and met with a coach at 3-month intervals when adherence data from the prior 3 months were reviewed with the participant. "Action-Focused Problem Solving" was used to address adherence barriers selected as important by the participant. Participants assigned to the control group met with coaches at 3-month intervals but received no feedback about adherence data. OUTCOMES The primary outcomes were electronically measured "taking" adherence (the proportion of prescribed doses of immunosuppressive medications taken) and "timing" adherence (the proportion of doses of immunosuppressive medications taken between 1 hour before and 2 hours after the prescribed time of administration) on each day of observation. Secondary outcomes included the standard deviation of tacrolimus trough concentrations, self-reported adherence, acute rejection, and graft failure. RESULTS 81 patients were assigned to intervention (median age, 15.5 years; 57% male) and 88 to the control group (median age, 15.8 years; 61% male). Electronic adherence data were available for 64 intervention and 74 control participants. Participants in the intervention group had significantly greater odds of taking prescribed medications (OR, 1.66; 95% CI, 1.15-2.39) and taking medications at or near the prescribed time (OR, 1.74; 95% CI, 1.21-2.50) than controls. LIMITATIONS Lack of electronic adherence data for some participants may have introduced bias. There was low statistical power for clinical outcomes. CONCLUSIONS The multicomponent TAKE-IT intervention resulted in significantly better medication adherence than the control condition. Better medication adherence may result in improved graft outcomes, but this will need to be demonstrated in larger studies. TRIAL REGISTRATION Registered at ClinicalTrials.gov with study number NCT01356277.

Abstract
BACKGROUND The neuroanatomic basis for cognitive impairment in chronic kidney disease (CKD) is incompletely characterized. We performed advanced quantitative structural magnetic resonance imaging (MRI) to determine whether CKD affects brain structure and whether poorer neurocognitive performance in CKD is associated with structural brain differences. STUDY DESIGN Cross-sectional. SETTING & PARTICIPANTS 85 individuals with CKD stages 2 to 5 and 63 healthy controls, aged 8 to 25 years PREDICTORS: CKD versus control, estimated glomerular filtration rate (eGFR), and kidney transplant status were analyzed as predictors of MRI findings. MRI volumes in 19 prespecified regions of gray matter (GM), white matter (WM), and cerebrospinal fluid were analyzed as predictors of neurocognitive performance (median z scores) in 7 prespecified domains. OUTCOMES 19 prespecified brain regions of interest (ROIs) in 7 prespecified domains. Neurocognitive performance in 7 prespecified domains. MEASUREMENTS ROI volumes were compared in CKD versus controls using unadjusted t tests and analysis of covariance (ANCOVA). Associations of ROI volumes with eGFR and kidney transplant status in participants with CKD were analyzed using ANCOVA and linear regression. Associations of neurocognitive performance and ROI volumes were analyzed by linear regression. RESULTS Participants with CKD had lower whole-brain, cortical, and left parietal GM volumes than controls in unadjusted analyses, but no differences were found in adjusted analysis. In participants with CKD, lower eGFR was associated with higher WM volume in whole-brain (P=0.05) and frontal (P=0.04) ROIs, but differences were not significant after multiple comparisons correction. Kidney transplant recipients had lower GM volumes in whole-brain (P=0.01; Q=0.06), frontal (P=0.02; Q=0.08), and left and right parietal (P=0.01; Q=0.06; and P=0.03; Q=0.1) ROIs and higher whole-brain WM volume (P=0.04; Q=0.1). Neurocognitive performance in the CKD group was not associated with ROI volumes. LIMITATIONS Unable to assess changes in brain structure and kidney function over time; analysis limited to prespecified ROIs and neurocognitive domains. CONCLUSIONS CKD in children and young adults may be associated with lower GM and higher WM volumes in some ROIs. Differences were relatively subtle in the CKD group as a whole, but were more prominent in recipients of a kidney transplant. However, neurocognitive performance was not explained by differences in brain ROI volumes, suggesting a functional rather than structural basis for neurocognitive impairment in CKD.

Abstract
The purpose of this paper is to address the potential use of cognitive remediation interventions for children and adolescents with chronic kidney disease (CKD) and end-stage kidney disease (ESKD). The prevalence and risk for neurocognitive dysfunction in children with this condition remains high, but, to date, interventions targeting these challenges have not been attempted either individually or as part of a larger treatment program. This is the next logical step in addressing the neurocognitive dysfunction that can be present in pediatric CKD/ESKD, with the field needing to determine the efficacy of cognitive remediation approaches for this population. To our knowledge, this paper is the first to raise this possibility by identifying candidate treatments addressing the neurocognitive challenges observed in children and adolescents with CKD/ESKD. Initially, we present the rationale for the importance of addressing the cognitive difficulties in this population, including an overview of the literature documenting the neurocognitive deficits associated with pediatric-onset CKD/ESKD. This is followed by a review of five candidate cognitive remediation programs that may be applicable to patients with this condition, and associated factors that could affect such treatment. The paper concludes with suggestions for both clinical and research initiatives that could be implemented to examine cognitive remediation as potential components of a larger treatment program for children and adolescents with CKD/ESKD.

Abstract
BACKGROUND Serious chronic illness can have a detrimental effect on school attendance, participation and engagement, leaving affected students at risk of failing to meet their developmental potential. An improved understanding of factors that help to explain or mitigate this risk can help educators and health professionals deliver the most effective support. This meta-review critiqued the available evidence examining the link between six chronic illnesses (asthma, cancer, chronic kidney diseases, heart diseases, cystic fibrosis and gastrointestinal diseases) and children's and adolescents' school experiences and outcomes, as well as investigating the medical, school, psychosocial and sociodemographic factors that are linked to poorer or better school outcomes. METHODS We searched CINAHL, Cochrane Database, EMBASE, ERIC, MEDLINE, ProQuest Theses and Dissertations, and PsycINFO (2000-2015). Systematic and narrative reviews, and meta-analyses, of original studies examining students' subjective school experiences and objective school outcomes were eligible. We used the Preferred Reporting Items for Systematic Reviews and Meta-analyses criteria to critically appraise all systematic reviews. The Grading of Recommendations Assessment, Development, and Evaluation system guided our recommendations for practice and research. RESULTS Eighteen reviews of 172 studies including more than 40 000 students were eligible. Therefore, we chose to conduct a meta-review to provide an overview of the literature on the relationship between chronic illness and school experiences and outcomes. We also explored the associated medical, school, psychosocial and sociodemographic factors affecting the relationship between illness and school experiences and outcomes. CONCLUSION Students with chronic illness demonstrate mixed school experiences and outcomes that are often worse than students without chronic illness. Modifiable factors, such as students' engagement with school, may be novel yet appropriate targets of educational support to ensure that these students reach their full schooling potential.

Abstract
The prevalence of chronic or end-stage kidney disease in pediatric girls is lower than in boys, however, girls have unique morbidities that can have great effect on their quality of life. For female adolescents, creatinine excretion peaks at approximately 14 years of age and is significantly less than males, owing to lower muscle mass. Females have higher nitric oxide activity, and estrogens may contribute to lower blood pressure. Females excrete less growth hormone during the prepubertal and pubertal years. Females between the ages of 8 and 10 years show increased levels of parathyroid hormone and vitamin D, however, female adolescents with chronic kidney disease have less estrogen and loss of the luteinizing hormone pulsatile pattern. These biological, hormonal, and physical changes affect the psychosocial aspects of female adolescents with chronic kidney disease/end-stage kidney disease, and they must learn to manage their health to achieve good outcomes. Patients and their parents must learn disease management through a customized health care transition preparation in both the pediatric- and adult-focused settings. Clinical strategies are suggested for the care of these special patients.

Abstract
Both acute kidney injury (AKI) and chronic kidney disease (CKD) are seen more frequently in the neonatal intensive care unit (NICU) as advances in supportive care improve the survival of critically ill infants as well as those with severe, congenital kidney and urinary tract anomalies. Many aspects of the infant's care, including fluid balance, electrolyte and mineral homeostasis, acid-base balance, and growth and nutrition require close monitoring by and collaboration among neonatologists, nephrologists, dieticians, and pharmacologists. This educational review summarizes the therapies widely used for neonates with AKI and CKD. Use of these therapies is extrapolated from data in older children and adults or based on clinical experience and case series. There is a critical need for more research on the use of therapies in infants with kidney disease as well as for the development of drug delivery systems and preparations scaled more appropriately for these small patients.

Abstract
BACKGROUND End-stage renal disease (ESRD) in children is associated with impaired neurocognitive function and development. However, data on factors associated with neurocognitive dysfunctions in children with kidney transplants are limited. METHODS We conducted a cross-sectional analysis comparing cognitive functions (using the Woodcock-Johnson International Edition, WJIE) in 35 kidney transplant and 35 healthy control children. Data on laboratory measurements, comorbidities, and social characteristics were collected. RESULTS Transplant children had significantly worse scores on the intelligence quotient (IQ) test compared with controls [Full Scale IQ score 85 (26) vs 107 (10), p <0.001]. Lower maternal education level was significantly associated with lower WJIE cognitive test scores; however, no association was found between laboratory values and WJIE scores. Among children with kidney transplants, those with medical comorbid conditions had significantly lower Verbal Ability and Full Scale IQ scores. Earlier age of dialysis onset and a longer total time on dialysis (>9 months) were associated with lower test scores. Age-standardized duration of hospitalization was inversely correlated with IQ (r = -0.46, p <0.01) and was an independent significant predictor (Beta = -0.38, p = 0.02) of IQ scores in transplanted children. CONCLUSIONS Child kidney transplant recipients have neurocognitive function impairments that are associated with markers of socioeconomic status (SES) and factors related to disease severity.

Abstract
The prevalence of sleep disorders during childhood has been estimated to range from 25 to 43 %. The aim of this review is to determine the prevalence of sleep disorders and possible associations with chronic kidney disease (CKD)-related factors and health-related quality of life (HRQOL) in children with CKD. An electronic systematic literature search for sleep disorders in children with CKD in Pubmed, Embase and the Cochrane Library Databases identified seven relevant articles for review, all of which reported an increased prevalence of sleep disorders in children with CKD. Five studies included children with CKD undergoing dialysis, and two studies included only non-dialysis patients. In all studies the presence of sleep disturbances was assessed by questionnaires; only one study compared the results of a validated questionnaire with laboratory-based polysomnography. The prevalence of any sleep disorder ranged from 77 to 85 % in dialysis patients, to 32-50 % in transplanted patients and 40-50 % in non-dialysis patients. The most commonly studied disorder was restless legs syndrome, which presented at a prevalence of 10-35 %. Three studies showed significant associations between presence of sleep disorders and HRQOL. We found consistent evidence of an increased prevalence of sleep disturbances in children with CKD, and these seemed to play a critical role in HRQOL.

Abstract
BACKGROUND Little information is available regarding the clinical characteristics and prevalence of complications in children with chronic kidney disease (CKD), especially in early disease stages. The objective of this study was to determine the clinical characteristics and prevalence of complications in children with predialytic CKD. METHODS This multicenter, cross-sectional study enrolled children at all stages of predialytic CKD. Children who were between the ages of 1 year and 18 years and who fulfilled the clinical criteria of CKD were included in the study. Baseline demographic data, previous history, clinical characteristics, and laboratory data were collected. RESULTS A total of 757 children were included in the study. The median age at the time of enrollment was 10.6 years; 397 patients (52.4 %) were males. A total of 39.0 % of the patients were in CKD stage 1, 37.6 % were in stage 2, 14.8 % were in stage 3, 3.0 % were in stage 4, and 5.5 % were in stage 5. Nonglomerular renal diseases were the primary cause of CKD, comprising 51.9 % of the patients with CKD. The age at disease onset, gender, CKD stage distribution, and proportion of co-morbidities varied between the glomerular and nonglomerular CKD cases. Anemia, hyperlipidemia, hypocalcemia, and hyperphosphatemia were more prevalent in patients with glomerular CKD. The overall prevalence of complications was as follows: uncontrolled blood pressure, 44.1 %; anemia, 34.2 %; hyperlipidemia, 44.9 %; short stature, 10.3 %; and failure to thrive, 8.2 %. Uncontrolled blood pressure (BP), anemia, and hyperlipidemia were common, even in the early CKD stages. The prevalence of CKD complications generally increased with the worsening stage of CKD. CONCLUSIONS This study reveals differences in CKD etiology and prevalence of specific complications according to the stage of CKD. Early recognition and awareness of complications are mandatory for clinicians during the follow-up visits of children with CKD.

Abstract
BACKGROUND AND OBJECTIVES We evaluated rates and factors associating with late referral (LR) and describe association of LR with access to renal transplantation and patient survival in children in the United Kingdom. Early requirement of RRT within 90 days of presentation to a pediatric nephrologist was classed as a LR, and those >90 days as an early referral (ER). DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS We included patients who commenced RRT, aged ≥3 months and <16 years, from 1996 to 2012. RESULTS Of 1603 patients, 25.5% (n=408) were LR, of which 75% commenced RRT in <30 days following presentation. Those with LR were more likely to be older at presentation, female, and black. The primary renal disease in LR was more likely to be glomerular disease (odds ratio [OR], 1.6; 95% confidence interval [95% CI], 1.12 to 2.29), renal malignancy and associated diseases (OR, 4.11; 95% CI, 1.57 to 10.72), tubulo-interstitial diseases (OR, 2.37; 95% CI, 1.49 to 3.78), or an uncertain renal etiology (OR, 5.75; 95% CI, 3.1 to 10.65). Significant differences in rates of transplantation between LR and ER remained up to 1-year following commencement of dialysis (21% versus 61%, P<0.001) but with no differences for donor source (33.3% and 35.3% living donor in LR and ER respectively, P=0.55). The median (interquartile range) follow-up time was 4.8 years (2.9-7.6). There were 55 deaths with no statistically significant difference in survival in the LR group compared with the ER group (hazard ratio, 1.30; 95% CI, 0.7 to 2.3; P=0.40). CONCLUSIONS We found that 25% of children starting RRT in the United Kingdom receive a LR to pediatric renal services, with little change observed over the past two decades. Those with LR are unable to benefit from pre-emptive transplantation and require longer periods of dialysis before transplantation. There is an urgent need to understand causes of avoidable LR and develop strategies to improve kidney awareness more widely among health care professionals looking after children.

Obsessive Compulsive Inventory-Child Version (OCV-CI) to Evaluate Obsessive Compulsive Disorder in Children With Early Stages of Chronic Kidney Disease: A Case Control Study. Nephrourol Mon 2016; 8:e34017.

Abstract
Background: Chronic kidney disease (CKD) is a common medical condition among children and obsessive-compulsive disorder (OCD) is a frequent, chronic, costly, and disabling disorder among them. Objectives: The aim of this study was to investigate obsessive-compulsive disorder (OCD) in children with early stages of CKD, and to compare it with the occurrence of OCD in healthy children. Patients and Methods: In this case-control study, we evaluated 160 children aged 7 to 17 years old who were visited in the pediatric clinics of Amir-Kabir hospital, Arak, Iran. The control group consisted of 80 healthy children and the case group included 80 children with Stage 1 to 3 CKD. The ages and sex of the children in the two groups were matched. OCD in children was evaluated using the obsessive compulsive inventory-child version (OCI-CV). Results: The mean scores of doubting/checking (case: 3.52 ± 2.54, control: 2.5 ± 2.32, P = 0.007) and ordering (case: 2.59 ± 1.81, control: 1.5 ± 2.56, P = 0.005) in the children with CKD was significantly higher than in the healthy ones. Moreover, the mean total scores for the OCI-CV of the children with CKD at 15.32 ± 7.69 was significantly higher than the scores of the healthy ones at 11.12 ± 2.54 (P = 0.021). There was a significant correlation between the CKD duration and doubting/checking (P = 0.004, correlation coefficient (CC): 0.4), obsessing (P = 0.06, CC: 0.02), washing (P = 0.031, CC: 0.8), ordering (P = 0.001, CC: 0.2), and the total scores of the OCI-CV questionnaire (P = 0.04, CC: 0.4). Conclusions: The risk of OCD in children with CKD is significantly higher than that in healthy children. Although the results seem to suggest that psychiatric intervention can be helpful in treating OCD in children with CKD, further investigation into the medical condition is required so as to obtain more definitive conclusions.

Abstract
OBJECTIVE To compare behavior ratings of executive functioning in individuals with chronic kidney disease (CKD), using the Behavior Rating Inventory for Executive Functions (BRIEF), with a typically developing comparison group and to examine the correlation between disease severity and ratings of executive functioning. METHODS Participants included 92 individuals with CKD (eGFR < 90 mL/min per 1.73 m), aged 8 to 25 years, recruited from nephrology clinics in both hospital and community settings. The disease severity ranged from CKD Stage II to V. The BRIEF was completed by parents for individuals younger than 18 years of age and the BRIEF-Adult was completed by individuals who were older than 18. RESULTS For individuals with CKD younger than 18 years of age, the parent-reported BRIEF revealed significant group differences when compared with controls on the Metacognition Index and the individual scales of Initiate, Working Memory, and Plan/Organize. A large proportion of individuals with CKD were rated as being at-risk for executive dysfunction. For the individuals of 18 years of age and older, there were no significant group differences. The relationship between BRIEF ratings and disease severity was limited to a few scales across both versions of the BRIEF. CONCLUSION This study supported the presence of executive dysfunction through a parent report, although the level of impairment was mild and its association with disease severity was related to select executive functions. Few difficulties were reported by older adolescents and young adults with CKD. It will be important for developmental-behavioral pediatricians to be cognizant of the level and pattern of executive function capabilities in their patients with CKD, and possible discrepancies with parent reports, so as to facilitate their management and transition planning.
