Adolescent and caregiver perceptions of addressing mental health in inflammatory bowel disease.

Adolescents with inflammatory bowel disease (IBD) are at an increased risk of anxiety and depression compared to peers, but availability of mental health services in IBD clinics does not meet patients' needs, and use of primary care services for mental health screening and care is low. This study provides qualitative data regarding adolescent and caregiver perspectives on addressing mental health in IBD. Interviews were conducted with adolescents with IBD and caregivers of adolescents with IBD. Interview transcripts were coded and analyzed for prominent themes. Thirteen adolescents and fourteen caregivers were interviewed. Three primary themes emerged: mental health stigma makes discussing it more difficult, physician-adolescent trust makes conversations about mental health easier, and asking about mental health directly can help adolescents feel comfortable. Adolescents and caregivers highlighted the importance of considering each patient and their family individually when choosing how to discuss mental health. Fostering trust with adolescents with IBD is vital to addressing mental health. While encouraging standardized screening is important, the most patient-centered approach to mental health involves considering families individually to identify and address mental health challenges. Given the increased risk of anxiety and depression in pediatric patients with IBD, all providers encountering these patients should be equipped to discuss mental health non-judgmentally.

Limitations of U25 CKiD and CKD-EPI eGFR formulae in patients 2-20 years of age with measured GFR > 60 mL/min/1.73 m2-a cross-sectional study.

BACKGROUND: When applying Pierce U25 formula for estimating glomerular filtration rate (eGFR), we observed a higher proportion of eGFR < 90 mL/min/1.73 m2 (chronic kidney disease (CKD) stage 2). We compared agreement and accuracy of the Pierce U25 (ages 2-25), Pottel (ages 2-100), and CKD-EPI (ages 18-100) formulae to GFR measurements. METHODS: Post hoc analysis of the three eGFRs compared to 367 99m technetium-diethylene-triamine penta-acetic acid (99Tc DTPA) GFR measurements (240 patients) using 3 sampling points and Brockner/Mørtensen correction (body surface area calculation based on ideal weight) on simultaneous serum creatinine and cystatin C measurements. RESULTS: Overall, the U25 formula performed well with a Spearman r of 0.8102 (95% confidence interval 0.7706 to 0.8435, p < 0.0001) while diagnostic accuracy was low in patients with normal mGFR. The U25 formula reclassified 29.5% of patients with normal mGFR as CKD stage 2; whereas the average of the modified Schwartz formula based on serum creatinine and the Filler formula based on cystatin C, only over-diagnosed CKD stage 2 in 8.5%, 24.5% within 10% and 62.7% within 30%. We therefore combined both. The average Schwartz/Filler eGFR had 36.5% of results within 10%, 84.7% within 30%, and normal mGFR accuracy was 26.8%, 63.9% for 10% and 30%, respectively, outperforming the CKD-EPI and Pottel formulae. CONCLUSIONS: The Pierce U25 formula results correlated well with mGFR < 75 mL/min/1.73 m2. Over the entire GFR range, accuracy was better for patients with a higher mGFR, when averaging the combined Schwartz/Filler formulae. More work is needed to prospectively confirm our findings in other centers.

In focus: perplexing increase of urinary stone disease in children, adolescent and young adult women and its economic impact.

Background: Urinary stone disease (USD) historically has affected older men, but studies suggest recent increases in women, leading to a near identical sex incidence ratio. USD incidence has doubled every 10 years, with disproportionate increases amongst children, adolescent, and young adult (AYA) women. USD stone composition in women is frequently apatite (calcium phosphate), which forms in a higher urine pH, low urinary citrate, and an abundance of urinary uric acid, while men produce more calcium oxalate stones. The reasons for this epidemiological trend are unknown. Methods: This perspective presents the extent of USD with data from a Canadian Province and a North American institution, explanations for these findings and offers potential solutions to decrease this trend. We describe the economic impact of USD. Findings: There was a significant increase of 46% in overall surgical interventions for USD in Ontario. The incidence rose from 47.0/100,000 in 2002 to 68.7/100,000 population in 2016. In a single United States institution, the overall USD annual unique patient count rose from 10,612 to 17,706 from 2015 to 2019, and the proportion of women with USD was much higher than expected. In the 10-17-year-old patients, 50.1% were girls; with 57.5% in the 18-34 age group and 53.6% in the 35-44 age group. The roles of obesity, diet, hormones, environmental factors, infections, and antibiotics, as well as the economic impact, are discussed. Interpretation: We confirm the significant increase in USD among women. We offer potential explanations for this sex disparity, including microbiological and pathophysiological aspects. We also outline innovative solutions - that may require steps beyond typical preventive and treatment recommendations.

A population-based retrospective cohort study of surgical trends and outcomes of pediatric urolithiasis in Ontario, Canada (2002-2019).

INTRODUCTION: The worldwide incidence of pediatric urinary stone disease (PUSD) is increasing. However, there is no commensurate data on whether this translates to an increasing need for surgical intervention for PUSD, given the role of conservative management. OBJECTIVE: We aimed to evaluate the trends and outcomes of clinically significant PUSD, using administrative databases to identify patients surgically treated for PUSD. STUDY DESIGN: This retrospective population-based cohort study assessed the incidence and trends of surgically treated PUSD and outcomes in Ontario, Canada in patients <18 years of age who underwent their first PUSD procedure between 2002 and 2019 utilizing administrative databases held at the Institute of Clinical Evaluative Sciences (ICES). We assessed the incidence of surgically treated PUSD, demographics, initial surgical treatment and imaging modality, and risk factors for repeat intervention within 5 years. Statistical analyses summarized demographics, surgical trends, and logistic regression was used to identify risk factors for repeat surgical intervention. RESULTS: We identified 1149 patients (mean age 11.3 years), with 59.6% older than 12 years. There was a decrease in the number of PUSD procedures performed per year that was close to statistical significance (p = 0.059) and a trend towards increased utilization of ureteroscopy (URS) compared with Shockwave Lithotripsy (SWL). In addition, there was a significant increase in the proportion of females surgically treated with PUSD (p = 0.001). In the 706 patients followed for 5 years, 17.7% underwent a repeat procedure within 6 months, while 20.4% underwent a repeat procedure from 6-months to 5 years. Renal stone location (OR 2.79, 95% confidence interval (CI) 1.62-4.80, p = 0.0002) and index SWL (OR 1.66, 95% CI 1.20-2.31, p = 0.0025) were risk factors for repeat surgical intervention within the first 6-months. There was an increasing utilization of ultrasound (US) compared to computerized tomography (CT) (p = 0.0008). DISCUSSION: Despite the literature reporting increasing PUSD incidence, we observed a non-significant decrease in the number of surgical PUSD procedures performed. Exclusion of those treated conservatively may explain our results. The increase in the proportion of females treated reflects the narrowing gender gap in stone disease. A trend towards increased URS utilization was observed and re-intervention rates were similar to previous studies. CONCLUSION: The overall rate of surgically treated PUSD did not show an increasing trend in Ontario, Canada from 2002 to 2019. URS was the most common surgical treatment modality, with a corresponding decline in SWL rates. PUSD was associated with a high surgical re-intervention rate within 6 months.

Kt/V or Bicarbonate: What Is More Important for Growth in Pediatric Peritoneal Dialysis Patients?

INTRODUCTION: Growth retardation is a common problem in pediatric patients with chronic kidney disease. It is unknown if the growth of children on peritoneal dialysis (PD) can be augmented by more dialysis. METHODS: We studied the effect of various peritoneal adequacy parameters on delta height standard deviation scores (SDSs) and growth velocity z-scores in 53 children (27 males) on PD, who underwent 2 longitudinal adequacy tests at 9-month intervals. None of the patients were on growth hormone. Intraperitoneal pressure and standard KDOQI guidelines were compared to the outcome measures delta height SDS and height velocity z-scores, using univariate and multivariate tests. RESULTS: At the time of the second PD adequacy test, their mean age was 9.2 ± 5.3 years; mean fill volume was 961 ± 254 mL/m2; and median total infused dialysate volume was 5.26 L/m2/day (range 2.03-15.32 L). The median total weekly Kt/V was 3.79 (range 0.9-9.5), and the median total creatinine clearance was 56.6 (range 7.6-133.48) L/week, higher than previous pediatric studies. The delta height SDS was a median of -0.12 (range -2 to +3.95)/year. The mean height velocity z-score was -1.6 ± 4.0. The only relationships discovered were between the delta height SDS and age, bicarbonate, and intraperitoneal pressure, but not for Kt/V or creatinine clearance. CONCLUSION: Our findings highlight the importance of normalization of bicarbonate concentrations to improve height z-score.

Artificial Intelligence in Pediatric Nephrology-A Call for Action.

Artificial intelligence is playing an increasingly important role in many fields of clinical care to assist health care providers in patient management. In adult-focused nephrology, artificial intelligence is beginning to be used to improve clinical care, hemodialysis prescriptions, and follow-up of transplant recipients. This article provides an overview of medical artificial intelligence applications relevant to pediatric nephrology. We describe the core concepts of artificial intelligence and machine learning and cover the basics of neural networks and deep learning. We also discuss some examples for clinical applications of artificial intelligence in pediatric nephrology, including neonatal kidney function, early recognition of acute kidney injury, renally cleared drug dosing, intrapatient variability, urinary tract infection workup in infancy, and longitudinal disease progression. Furthermore, we consider the future of artificial intelligence in clinical pediatric nephrology and its potential impact on medical practice and address the ethical issues artificial intelligence raises in terms of clinical decision-making, health care provider-patient relationship, patient privacy, and data collection. This article also represents a call for action involving those of us striving to provide optimal services for children, adolescents, and young adults with chronic conditions.

Translation and validation of the STARx questionnaire in transitioning Chinese adolescents and young adults with chronic health conditions.

BACKGROUND: Adolescent/young adults (AYAs) with chronic conditions must undergo healthcare transition (HCT) preparation until their mid-twenties. Valid HCT readiness measures are lacking in China. METHODS: The present study translated, back-translated, and adapted the Self-Management and Transition to Adulthood with Rx = Treatment (STARx) Questionnaire. We examined the psychometric properties of this tool in a relatively large in-patient sample of AYAs with various chronic health conditions at a Chinese tertiary general hospital. RESULTS: We enrolled 624 AYAs aged 10-25 years (19.66 ±â€¯3.64) with various chronic health conditions. The Chinese version of the STARx Questionnaire demonstrated excellent internal consistency (Cronbach's alpha = 0.83) and reliability with a two-week test-retest (ICC = 0.88, p < .001). Furthermore, the Chinese version revealed a three-factor structure (self-management, disease knowledge, and provider communication) consistent with the revised English version of the STARx Questionnaire. In terms of discriminant validity, the total score of the Chinese STARx Questionnaire showed a significant positive correlation with age but no gender differences were found. In terms of predictive validity, the Chinese STARx Questionnaire was significantly correlated with shorter length of hospitalization and higher frequency of emergency room visit, but the correlations became insignificant after controlling for age. CONCLUSIONS: The results suggest that the Chinese version of the STARx Questionnaire is a robust HCT readiness tool in AYAs with chronic conditions and clinicians may find it useful to develop individualized interventions.

The self-management and transition manual "ALL YOU NEED IS LOVE" for adolescents with chronic kidney disease.

PURPOSE: To examine the effects of "ALL YOU NEED IS LOVE", a novel six-week, self-directed patient education manual designed to improve chronic kidney disease knowledge/self-management, health care transition readiness, self-advocacy, and mindfulness skills among adolescents with chronic kidney disease. DESIGN AND METHODS: We enrolled 49 adolescents aged 11-17 years (mean age 14.7 ± 1.9; 53.1% males) from a university hospital kidney center who had CKD stages 3 and greater, who were randomly assigned into the "ALL YOU NEED IS LOVE" patient education only group (n = 31) or the "ALL YOU NEED IS LOVE" patient education plus mindfulness training group (n = 18). Participants completed Qualtrics surveys at baseline, post-intervention, and three-month follow-up. The survey included measures of outcome variables (i.e., self-management/transition readiness, patient self-advocacy, and mindfulness), and an additional demographic questionnaire was included in the baseline survey. Multilevel model analyses were used to examine the effects of group and time on the outcome variables. RESULTS: Multilevel model analyses showed an overall significant time effect across all outcome variables in both groups. However, the group effects were not statistically significant across the outcome variables. CONCLUSIONS: Both interventions significantly increased participants' self-management/HCT readiness, self-advocacy, and mindfulness over time. Mindfulness training may not bring additional benefits to the "ALL YOU NEED IS LOVE" education manual. PRACTICE IMPLICATIONS: Pediatric nurses and clinicians may utilize the self-directed "ALL YOU NEED IS LOVE" manual to increase self-management/transition readiness, self-advocacy, and mindfulness among adolescents with chronic kidney disease.

Histopathological Changes of Long-Term Peritoneal Dialysis Using Physiological Solutions: A Case Report and Review of the Literature.

BACKGROUND: Long-term peritoneal dialysis (PD), especially with nonphysiological solutions, is afflicted with the severe complication of encapsulating peritoneal sclerosis (EPS). Physiologic PD solutions have been introduced to reduce pH trauma. Data on peritoneal biopsies in pediatrics with long-term PD using physiological solutions are scant. CASE REPORT: We report an adolescent who had been on 10-h continuous hourly cycles using mostly 2.27% Physioneal™ for 5 years. There were two episodes of peritonitis in October 2017 (Klebsiella oxytoca) and May 2018 (Klebsiella pneumoniae), which were treated promptly. This adolescent, who lost two kidney transplants from recurrent focal and segmental glomerulosclerosis, underwent a peritoneal membrane biopsy at the time of a third PD catheter placement, 16 months after the second renal transplant. Laparoscopically, the peritoneum appeared grossly normal, but fibrosis and abundant hemosiderin deposition were noted on histology. The thickness of the peritoneum was 200-900 (mean 680) µm; normal for age of 14 years is 297 [IQR 229, 384] µm. The peritoneum biopsy did not show specific EPS findings, as the mesothelial cells were intact, and there was a lack of fibrin exudation, neo-membrane, fibroblast proliferation, infiltration, or calcification. CONCLUSIONS: While the biopsy was reassuring with respect to the absence of EPS, significant histopathological changes suggest that avoiding pH trauma may not ameliorate the effects of glucose exposure in long-term PD.

Renal Autologous Cell Therapy to Stabilize Function in Diabetes-Related Chronic Kidney Disease: Corroboration of Mechanistic Action With Cell Marker Analysis.

Introduction: Chronic kidney disease (CKD) is a worldwide disease without cure. Selected renal cells (SRCs) can augment kidney function in animal models. This study correlates the phenotypical characteristics of autologous homologous SRCs (formulated product called Renal Autologous Cell Therapy [REACT]) injected into patients' kidneys with advanced type 2 diabetes-related CKD (D-CKD) to clinical and laboratory findings. Methods: A total of 22 adults with type 2 D-CKD underwent a kidney biopsy followed by 2 subcortical injections of SRCs, 7 ± 3 months apart. There were 2 patients who had only 1 injection. We compared annualized estimated glomerular filtration rate (eGFR) slopes pre- and post-REACT injection using the 2009 CKD-EPI formula for serum creatinine (sCr) and the 2012 CKD-EPI Creatinine-Cystatin C equation and report clinical/laboratory changes. Fluorescent Activated Cell Sorting (FACS) Analysis for renal progenitor lineages in REACT and donor vascular endothelial growth factor A (VEGF-A) analysis were performed. Longitudinal parameter changes were analyzed with longitudinal linear mixed effects model. Results: At baseline, the mean diabetes duration was 18.4 ± 8.80 years, glycated hemoglobin (Hgb) was 7.0 ± 1.05, and eGFR was 40.3 ± 9.35 ml/min per 1.73 m2 using the 2012 CKD-EPI cystatin C and sCr formulas. The annualized eGFR slope (2012 CKD-EPI) was -4.63 ml/min per 1.73 m2 per year pre-injection and improved to -1.69 ml/min per 1.73 m2 per year post-injection (P = 0.015). There were 7 patients who had an eGFR slope of >0 ml/min per 1.73 m2 postinjection. SRCs were found to have cell markers of ureteric bud, mesenchyme cap, and podocyte sources and positive VEGF. There were 2 patients who had remote fatal adverse events determined as unrelated with the biopsies/injections or the REACT product. Conclusion: Our cell marker analysis suggests that SRCs may enable REACT to stabilize and improve kidney function, possibly halting type 2 D-CKD progression.

Growth hormone therapy in HHRH.

Background: Hereditary Hypophosphatemic Rickets with Hypercalciuria (HHRH) (SLC34A3 gene, OMIM 241530) is an autosomal recessive disorder that results in a loss of function of the sodium-phosphate NPT2c channel at the proximal tubule. Phosphate supplementation rarely improves serum phosphate, hypercalciuria, nephrocalcinosis, 1,25(OH)2 vitamin D (1,25(OH)2D) levels or short stature. Methods: We describe 23Na MRI and the successful use of recombinant human growth hormone (rhGH) and Fluconazole to improve growth (possibly confounded by puberty) and hypercalciuria in a now 12-year-old male with HHRH (novel homozygous SLC34A3 mutation, c.835_846 + 10del.T). Results: The patient had chronic bone pain, hypophosphatemia (0.65 mmol/L[reference interval 1.1-1.9]), pathological fractures and medullary nephrocalcinosis/hypercalciuria (urinary calcium/creatinine ratio 1.66 mol/mmol[<0.6]). TmP/GFR was 0.65 mmol/L[0.97-1.64]; 1,25(OH)2D was >480 pmol/L[60-208]. Rickets Severity Score was 4. Treatment with 65 mg/kg/day of sodium phosphate and potassium citrate 10 mmol TID failed to correct the abnormalities.Adding rhGH at 0.35 mg/kg/week to the phosphate therapy, improved bone pain, height z-score from -2.09 to -1.42 over 6 months, without a sustained effect on TmP/GFR. Fluconazole was titrated to 100 mg once daily, resulting for the first time in a reduction of the 1,25(OH)2D to 462 and 426 pmol/L; serum phosphate 0.87 mmol/L, and calcium/creatinine ratio of 0.73.23Na MRI showed normal skin (z-score + 0.68) and triceps surae muscle (z-score + 1.5) Na+ levels; despite a defect in a sodium transporter, hence providing a rationale for a low sodium diet to improve hypercalciuria. Conclusions: The addition of rhGH, Fluconazole and salt restriction to phosphate/potassium supplementation improved the conventional therapy. Larger studies are needed to confirm our findings.

Trends and Disparities in Health Care Transition Preparation from 2016 to 2019: Findings from the US National Survey of Children's Health.

OBJECTIVES: To evaluate national trends in health care transition preparation over a 4-year period using the National Survey of Children's Health (NSCH) and to identify and examine disparities in receipt of health care transition preparation over the study period. STUDY DESIGN: Data from the NSCH, an annual serial cross-sectional survey conducted from 2016 to 2019, were examined. Caregivers answered questions regarding one of their children within each of a random sample of households across the US. The primary analysis examined trends in health care transition preparation based on the year of survey completion. A secondary analysis examined the associations of race/ethnicity, primary household language, insurance type, and children with special health care needs (CSHCN) with receipt of health care transition preparation. RESULTS: We included data from 54 434 youths (20 708 in 2016, 8909 in 2017, 12 587 in 2018, and 12 230 in 2019) aged 12-17 years whose caregivers completed the NSCH between 2016 and 2019. The sample was weighted to be nationally representative based on weights provided by the NSCH. The proportion of youths receiving necessary health care transition preparation increased over the study period, from 14.8% in 2016 to 20.5% in 2019 (P < .001). Multivariable logistic regression demonstrated increased odds of receiving health care transition preparation in 2018 and 2019, as well as for White non-Hispanic youths, those with English or Spanish as a primary household language, those with private insurance, and CSHCN. CONCLUSIONS: Although the proportion of youths receiving health care transition preparation has increased since 2016, the need for ongoing improvement and elimination of disparities in health care transition preparation remains.
