Objective: To explore the use of entrustable professional activities (EPAs) in undergraduate medical education (UME), characterization of EPAs by pediatric educators, and opportunities and challenges with an EPA framework., Methods: In 2020, 9 survey questions were administered to members of the Council on Medical Student Education in Pediatrics, a national pediatric UME group. Clark's Commitment and Necessary Effort model on motivation served as the theoretical framework for our study. Quantitative and qualitative data were analyzed using descriptive statistics and conventional content analysis, respectively., Results: One hundred and sixty-seven (31%) of 479 recipients, representing 75% of accredited schools responded. Eigty-three percent agreed that they understood what EPAs were, yet a minority reported using EPAs. Eighty-five percent of EPA users expressed satisfaction with EPAs in providing a shared framework and an opportunity to track student competence; dissatisfaction was expressed toward faculty resource needs. Among nonusers, barriers hindering implementation included faculty development challenges and faculty time. Qualitative analyses revealed a rich understanding of EPAs: that they offer a framework to measure learner competence by assessing performance in workplace-based tasks that can be used for entrustment decisions and for program evaluation., Conclusions: Although most pediatric UME educators report understanding EPAs (contributing to self-efficacy) and recognize their benefits (value), a minority report actually using EPAs. EPAs, while providing a valuable framework, pose challenges from contextual factors affecting personal agency, which could affect educator commitment in implementation. For more widespread adoption of the EPAs, efforts should focus on minimizing these perceived barriers., (Copyright © 2021 Academic Pediatric Association. Published by Elsevier Inc.

Purpose: To explore when and in what form pediatric faculty and residents practice reflection., Method: From February to June 2015, the authors conducted focus groups of pediatric faculty and residents at the University of California, Davis; Stanford University; and the University of California, San Francisco, until thematic saturation occurred. Transcripts were analyzed based on Mezirow's and Schon's models of reflection, using the constant comparative method associated with grounded theory. Two investigators independently coded transcripts and reconciled codes to develop themes. All investigators reviewed the codes and developed a final list of themes through consensus. Through iterative discussions, investigators developed a conceptual model of reflection in the clinical setting., Results: Seventeen faculty and 20 residents from three institutions participated in six focus groups. Five themes emerged: triggers of reflection, intrinsic factors, extrinsic factors, timing, and outcome of reflection. Various triggers led to reflection; whether a specific trigger led to reflection depended on intrinsic and extrinsic factors. When reflection occurred, it happened in action or on action. Under optimal conditions, this reflection was goal and action directed and became critical reflection. In other instances, this process resulted in unproductive rumination or acted as an emotional release or supportive therapy., Conclusions: Participants reflected in clinical settings, but did not always explicitly identify it as reflection or reflect in growth-promoting ways. Strategies to enhance critical reflection include developing knowledge and skills in reflection, providing performance data to inform reflection, creating time and space for safe reflection, and providing mentorship to guide the process.

Objective: The objectives of this study were to explore pediatric undergraduate medical educators' understanding of reflective practice, the barriers they face in teaching this, the curricular activities they use, and the value they assign to reflective practice., Methods: Nine survey questions were sent to members of the Council on Medical Student Education in Pediatrics, an international pediatric undergraduate medical educator group. Quantitative data were analyzed using descriptive statistics. Open-ended responses were analyzed qualitatively through an iterative process to establish themes representing understanding of reflective practice and barriers in teaching this., Results: Respondents representing 56% of all North American schools answered at least 1 survey question. Qualitative analysis of understanding of reflection revealed 11 themes spanning all components of reflective practice, albeit with a narrow view on triggers for reflection and a lower emphasis on understanding the why of things and on perspective-taking. The most frequent barriers in teaching this were the lack of skilled educators and limited time. Most respondents valued reflective skills but few reported confidence in their ability to teach reflection. Several curricular activities were used to teach reflection, the most common being narrative writing., Conclusions: Pediatric undergraduate medical educators value reflection and endorse its teaching. However, many do not have a complete understanding of the construct and few report confidence in teaching this. Implementing longitudinal curricula in reflective practice may require a culture change; opportunities exist for faculty development about the meaning and value of reflective practice and how best to teach this., (Copyright © 2016 Academic Pediatric Association.

The Dreyfus and Bloom frameworks can help the great clinical teacher craft questions that are learner-centric and appropriately challenging.Employing strategies to ask the right questions in the right way can further add to the effectiveness of using questions as a valuable teaching,learning, and assessment tool.

Children with steroid-resistant nephrotic syndrome (SRNS) are at risk of developing renal failure. We report here the results of a single-center retrospective observational study of the remission rate in pediatric patients with SNRS receiving tacrolimus. Serial renal biopsies from children on tacrolimus therapy were evaluated for tubulointerstitial fibrosis and transforming growth factor-β immunostaining. Of the 16 children with SRNS, 15 went into complete remission after a median of 120 days of therapy. Nine children were able to stop steroids, while the others were on tapering doses. Forty-seven percent had relapses, most of which were steroid-responsive. Serial renal biopsies were obtained from seven children after a median treatment duration of 24 months; two of these children had increased tubulointerstitial fibrosis and four showed increased transforming growth factor-β tissue staining. Children with worsening histological findings were younger. There was no significant association between tacrolimus exposure and biopsy changes, although the average trough level was higher in those children with worsening histological findings. In conclusion, tacrolimus may be a safe and effective alternative agent for inducing remission in children with SRNS. However, caution needs to be taken when prescribing this agent due to its narrow therapeutic index. Serial renal biopsies are necessary to check for subclinical nephrotoxicity, especially in younger children and those with higher trough levels.

Diabetic kidney disease (DKD), previously encountered predominantly in adult patients, is rapidly gaining center stage as a childhood morbidity and one that pediatric nephrologists are likely to encounter with increasing frequency. This is in large part due to the obesity epidemic and the consequent rise in type 2 diabetes in children and adolescents, as well as the more aggressive diabetes phenotype in today's youth with more rapid β-cell decline and faster development and progression of diabetes-related complications along with lower responsiveness to the treatments used in adults. DKD, an end-organ complication of diabetes, is at the very least a marker of, and more likely a predisposing factor for, the development of adverse cardiovascular outcomes and premature mortality in children with diabetes. On an optimistic note, several new therapeutic approaches are now available for the management of diabetes in adults, such as GLP1 receptor agonists, SGLT2 inhibitors, and DPP4 inhibitors, that have also been shown to have a favorable impact on cardiorenal outcomes. Also promising is the success of very low-energy diets in inducing remission of diabetes in adults. However, the addition of these pharmacological and dietary approaches to the management toolbox of diabetes and DKD in children and adolescents awaits thorough assessment of their safety and efficacy in this population. This review outlines the scope of diabetes and DKD, and new developments that may favorably impact the management of children and young adults with diabetes and DKD. [ABSTRACT FROM AUTHOR]

Background: Hemodialysis (HD) guidelines recommend permanent vascular access (PVA) in children unlikely to receive kidney transplant within 1 year of starting HD. We aimed to determine predictors of primary and secondary patency of PVA in pediatric HD patients.Methods: Retrospective chart reviews were performed for first PVAs in 20 participating centers. Variables collected included patient demographics, complications, interventions, and final outcome.Results: There were 103 arterio-venous fistulae (AVF) and 14 AV grafts (AVG). AVF demonstrated superior primary (p = 0.0391) and secondary patency (p = 0.0227) compared to AVG. Primary failure occurred in 16 PVA (13.6%) and secondary failure in 14 PVA (12.2%). AVF were more likely to have primary failure (odds ratio (OR) = 2.10) and AVG had more secondary failure (OR = 3.33). No demographic, clinical, or laboratory variable predicted primary failure of PVA. Anatomical location of PVA was predictive of secondary failure, with radial having the lowest risk compared to brachial (OR = 12.425) or femoral PVA (OR = 118.618). Intervention-free survival was predictive of secondary patency for all PVA (p = 0.0252) and directly correlated with overall survival of AVF (p = 0.0197) but not AVG. Study center demonstrated statistically significant effect only on intervention-free AVF survival (p = 0.0082), but not number of complications or interventions, or outcomes.Conclusions: In this multi-center pediatric HD cohort, AVF demonstrated primary and secondary patency advantages over AVG. Radial PVA was least likely to develop secondary failure. Intervention-free survival was the only predictor of secondary patency for AVF and directly correlated with overall access survival. The study center effect on intervention-free survival of AVF deserves further investigation. [ABSTRACT FROM AUTHOR]

The utilization of en bloc renal allografts from small pediatric donors has been adopted as an effective strategy to expand the organ donor pool in adult recipients. Data in children are limited. The aim of our study is to describe the outcomes of en bloc renal transplants in children from our center. Medical records of children receiving pediatric en bloc renal transplants at our institution from January 2007 were abstracted. Data collected included recipient and donor demographics, operative technique and complications, and post-operative studies. Eight children received en bloc renal transplants at a median age of 17 yr; median follow-up was 0.9 yr. Donor body weight ranged from 4 to 22 kg. One kidney was lost to intra-operative thrombosis, while the other kidney from this en bloc graft remained viable. All grafts showed increased renal size at follow-up ultrasound. Surveillance biopsies showed glomerulomegaly in two patients. At last follow-up, the median e GFR was 130 mL/min/1.73 m2. The urinary protein to creatinine ratio was normal in four of seven patients. Our data suggest that in experienced centers, en bloc renal transplantation from young donors into pediatric recipients is effective. Long-term follow-up to monitor for complications, including hyperfiltration injury, is warranted. [ABSTRACT FROM AUTHOR]

Lau KK, Berg GM, Schjoneman YG, Perez RV, Butani L. Extended experience with a steroid minimization immunosuppression protocol in pediatric renal transplant recipients. Pediatr Transplantation 2010: 14:488–495. © 2009 John Wiley & Sons A/S. Purpose: To determine the safety and efficacy of a novel steroid minimization protocol after renal transplantation at a single Northern California center. Introduction: We have previously reported our experience on the short-term outcomes in eight children using our steroid minimization protocol. Herein, we present our ongoing experience in using this regimen in 20 children. Methods: Children receiving immunosuppression with a steroid minimization protocol at our center from 1/04 – 12/08 (Group 2) were retrospectively compared with 20 controls (Group 1). Results: At one-month follow-up, Group 2 was observed to have lower eGFR, hemoglobin, white cell count, and cholesterol. The incidence of adverse events during the first yr was comparable. Three patients in Group 1 displayed histological evidence of acute rejection, one patient in Group 2 developed humoral rejection; another patient in Group 2 had sub-clinical rejection. Surgical complications were observed in 20% of patients in both groups. While 10% of patients in Group 1 developed diabetes mellitus, none was observed in Group 2. Thirty and 40% of patients in Groups 1 and 2, respectively, suffered from infectious complications during the first yr. Conclusions: Our novel steroid minimization immunosuppression is safe in children and associated with no increased risk of rejection and infection. [ABSTRACT FROM AUTHOR]

Lau KK, Berg GM, Schjoneman YG, Perez RV, Butani L. Pediatric en bloc kidney transplantation into pediatric recipients. Pediatr Transplantation 2010: 14: 100–104. © 2009 John Wiley & Sons A/S. As a result of the ongoing shortage in organ supply, en bloc renal transplantation from small donors has become more common for adult recipients with ESRD. However, because of concern for higher complication rates and sub-optimal outcomes, it is not being performed in every center, and data describing its use in pediatric recipients are even more limited. We retrospectively studied three patients who have undergone en bloc renal transplantation at our center. Median age at transplantation was 16.7 yr with a median follow-up of 1.2 yr. Donor age ranged from nine to 49 months with weight ranging from 10 to 22 kg. There were no post-operative thrombotic complications. All grafts showed increased renal size at follow-up by ultrasound. There was no clinical or histological rejection at last follow-up. To the best of our knowledge, this is the first report on the outcomes of en bloc kidney transplantation from pediatric donors into pediatric recipients. Based on our experience, albeit very limited, we feel that en bloc renal transplantation from young donors is an acceptable and safe procedure with low complication rates in pediatric recipients and should be given consideration to minimize wait times on the wait list and to improve quality of life.

To determine the outcomes of pediatric renal transplant recipients who received immunosuppression consisting of early withdrawal of corticosteroids at a single Northern California center. Protocols using minimal steroid exposure have been recently reported in adult transplant recipients with successful results. We examined the outcomes of pediatric renal transplant recipients who were managed at our center using a protocol with very early discontinuation of steroids after renal transplantation. We retrospectively studied the medical records of all renal transplant recipients followed at the Children’s Hospital at the University of California, Davis Medical Center from 01/2004 to 12/2005. All patients were less than 18 yr of age at the time of transplantation. The immunosuppressive protocol included three tapering daily doses of methylprednisolone, together with five doses of thymoglobulin followed by maintenance therapy with tacrolimus and MMF. Eight patients with equal numbers of males and females were transplanted during this time period. There were equal numbers of Caucasians, African-Americans, Hispanics, and Asians. A total of 37.5% (3/8) of the subjects received preemptive transplantation, 25% (2/8) received peritoneal, and 37.5% (3/8) received hemodialysis before transplantation. The median (range) age at transplantation was 12.3 (3.1–16.0) year with a follow-up of 1.7 (0.9–2.8) year. At one yr post-transplantation, 57% (4/7) of patients still required anti-hypertensives. Three children required erythropoietin supplementation after transplantation. The mean delta height standard deviation score at 12 months was 0.20 ± 0.56. There were no episodes of clinical acute rejection. One patient switched from tacrolimus to sirolimus due to biopsy-proven CAN. No patient became diabetic or required hypoglycemic agents. Surveillance biopsies showed no subclinical acute rejection in any patient. Steroid-free immunosuppression is safe in children after renal transplantation. Larger number of patients and longer follow-up are required to further confirm the effectiveness and safety of immunosuppression with rapid steroid discontinuation. [ABSTRACT FROM AUTHOR]

Because of its narrow therapeutic index, monitoring of drug exposure is recommended for tacrolimus (T). Limited data are available on kinetics of T in children after transplantation. Our study investigated the correlation between T trough and the area under the time-concentration curve (AUC) in pediatric renal transplant recipients and investigated the effect of steroids. Data on T troughs and two h and four h post-dose concentrations over the first post-transplant year in 20 transplant recipients from August 2001 to June 2005 were analyzed. Patients were analyzed in two groups based on their use of steroids. Although the overall correlation between the troughs and AUC was good (r = 0.85, Pearson test), during the first month the correlation was poor in the cohort receiving steroids (r = 0.5) compared with those on a steroid minimization regimen (r = 0.9). In 85% of patients there was a discrepancy between the trough and AUC leading to errors in dose adjustment. In conclusion, although the overall correlation between T trough and AUC is good, it is suboptimal in the first post-transplant month in children receiving steroids. Because of large variation in exposure, we recommend AUC monitoring for T. Prospective studies are needed to determine the impact of more accurate monitoring of T exposure on outcomes.

Hyperlipidemia is common after renal transplantation (Tx) and contributes to the increased cardiovascular morbidity seen in the post-transplant period. Limited data are available on the utility of the statins in children after renal Tx. This 12-month prospective study was undertaken to determine the efficacy of pravastatin in reducing dyslipidemia after renal Tx in children and to determine predictors of dyslipidemia after Tx. From August 2001 to April 2004, all 17 newly transplanted pediatric renal transplant recipients at our center were preemptively treated with pravastatin from the immediate post-transplant period. Fasting lipid profiles were obtained at 1, 3, 6 and 12 months after Tx. Trends in the lipid profile were analyzed using the repeated measures general linear model (GLM). A historical cohort of pediatric renal-transplant recipients not treated with pravastatin was used as the control population. The mixed effects GLM was used for multivariable logistic regression analyses to determine the independent effect of age, pretransplant cholesterol (Chol), body mass index (BMI), creatinine clearance (CrCl), and corticosteroid and tacrolimus doses on the development of dyslipidemia. The mean age of the children at Tx was 8.7 yr. The GLM analysis showed that with time, there was a significant decline in the total Chol, serum triglyceride (TG), LDL and also HDL-Chol (p-value <0.05 for each). Compared with the controls, the mean serum Chol was lower at all time points post-transplant in the treated patients. However, despite treatment, the prevalence of hypercholesterolemia increased from 31% pretransplant to 53% at 1-month, but declined thereafter to 6% at 3 and 6 months and 0% at 1 yr. Multivariable regression analyses showed the prednisone dose, pretransplant Chol and age to be the most important risk factors for the development of dyslipidemia. No child developed complications related to therapy. In summary, pravastatin is safe in the post-transplant period in children and reduces serum Chol, LDL-Chol and TG. An unexpected finding in our study was the decline in HDL-Chol after Tx. Whether the preemptive use of the statins will result in lower cardiovascular morbidity, especially considering the concomitant reduction in HDL-Chol remains to be determined. [ABSTRACT FROM AUTHOR]

Truong U, Moon-Grady AJ, Butani L. Cardiac tamponade in a pediatric renal transplant recipient on sirolimus therapy. Pediatr Transplantation 2005: 9: 541–544. © 2005 Blackwell Munksgaard Because of its lack of nephrotoxicity, the use of sirolimus, as an immunosuppressive agent, has increased considerably in solid-organ transplant (Tx) recipients. With its increased use, Tx professionals are encountering a variety of previously unreported side-effects such as angioedema and interstitial pneumonitis. We describe here the case of a pediatric renal Tx recipient who, while receiving sirolimus, developed a large pericardial effusion requiring pericardiocentesis. An extensive workup for an infectious etiology was performed; the only positive result was isolation of adenovirus type 2 from the patient's stool specimen. Following sirolimus dose reduction this child's effusion stabilized and has not recurred. The purpose of this report is to advise health-care professionals caring for Tx recipients about this potentially life-threatening complication associated with sirolimus. The role of adenovirus, if any, in contributing to the development of our patient's pericardial effusion is discussed herein. [ABSTRACT FROM AUTHOR]
