Implementing Entrustable Professional Activities in Pediatric Fellowships: Facilitating the Process.

BACKGROUND AND OBJECTIVES: Entrustable professional activities (EPAs) will be used for initial certification by the American Board of Pediatrics by 2028. Less than half of pediatric fellowships currently use EPAs for assessment, yet all will need to adopt them. Our objectives were to identify facilitators and barriers to the implementation of EPAs to assess pediatric fellows and to determine fellowship program directors' (FPD) perceptions of EPAs and Milestones. METHODS: We conducted a survey of FPDs from 15 pediatric subspecialties. EPA users were asked about their implementation of EPAs, barriers encountered, and perceptions of EPAs. Nonusers were queried about deterrents to using EPAs. Both groups were asked about potential facilitators of implementation and their perceptions of Milestones. RESULTS: The response rate was 65% (575/883). Of these, 344 (59.8%) were EPA users and 231 (40.2%) were nonusers. Both groups indicated work burden as a barrier to implementation. Nonusers reported more barriers than users (mean [SD]: 7 [3.8] vs 5.8 [3.4], P < .001). Both groups identified training materials and premade assessment forms as facilitators to implementation. Users felt that EPAs were easier to understand than Milestones (89%) and better reflected what it meant to be a practicing subspecialty physician (90%). In contrast, nonusers felt that Milestones were easy to understand (57%) and reflected what it meant to be a practicing subspecialist (58%). CONCLUSIONS: Implementing EPA-based assessment will require a substantial investment by FPDs, facilitated by guidance and easily accessible resources provided by multiple organizations. Perceived barriers to be addressed include FPD time constraints, a need for additional assessment tools, and outcomes data.

Level of Supervision for the Entrustable Professional Activities Common to General Pediatrics and the Subspecialties Decreases from Residency to Fellowship.

OBJECTIVES: To compare level of supervision (LOS) ratings of graduating pediatric residents with their assessments as fellows for the five Entrustable Professional Activities (EPAs) common to general pediatrics and the subspecialties and to determine if the difference between ratings from residency to fellowship is less for the QI and Practice Management EPAs, since the skills needed to perform these may be less context-dependent. METHODS: We compared ratings of graduating residents with their assessments as fellows using LOS data from two sequential EPA studies. RESULTS: There were 65 ratings from 41 residents at the first fellow assessment. At graduation, most residents needed little to no supervision for all EPAs with 94% (61/65) of ratings level four or five. In contrast, only 5/65 (8%) of the first fellow assessments were level four or five. The ratings difference for the QI and Practice Management EPAs was similar to the others. CONCLUSIONS: LOS ratings for the EPAs common to generalists and subspecialists reset as residents become fellows. There was no evidence that the QI and Practice Management EPAs are less context-dependent. This study provides additional validity evidence for using these LOS scales to assess trainees in pediatric residency and fellowship.

A phase 1 study of mebendazole with bevacizumab and irinotecan in high-grade gliomas.

BACKGROUND: High-grade gliomas (HGG) have a dismal prognosis despite multimodal therapy. Mebendazole is an anti-helminthic benzimidazole that has demonstrated efficacy in numerous in vitro cancer models, and is able to cross the blood-brain barrier. We conducted a phase 1 trial (NCT01837862) to evaluate the safety of mebendazole in combination with bevacizumab and irinotecan in children and young adults with HGG. OBJECTIVE: To determine the maximally tolerated dose of mebendazole when given in combination with bevacizumab and irinotecan in children with HGG; to describe the progression-free survival (PFS) and overall survival (OS) for this group. DESIGN/METHOD: Patients between 1 and 21 years of age with HGG were enrolled in a 3 + 3 design to escalating doses of mebendazole in combination with bevacizumab (10 mg/kg/dose) and irinotecan (150 mg/m2 /dose). Subjects were eligible upfront after completion of radiation or at the time of progression. Mebendazole was taken orally twice per day continuously, and bevacizumab and irinotecan were given intravenously on Days 1 and 15 of 28-day cycles. RESULTS: Between 2015 and 2020, 10 subjects were enrolled at mebendazole doses of 50 mg/kg/day (n = 3), 100 mg/kg/day (n = 4), and 200 mg/kg/day (n = 3). One subject assigned to 100 mg/kg/day was not evaluable. Seven subjects had a diagnosis of diffuse midline glioma, one subject had anaplastic astrocytoma, and one subject had a spinal HGG. All subjects received radiation. There were no dose-limiting toxicities. The most frequent G3/4 adverse events were neutropenia (n = 3) and lymphopenia (n = 4). The overall response rate was 33%, with two subjects achieving a partial response and one subject achieving a complete response sustained for 10 months. The mean PFS and OS from the start of study treatment were 4.7 and 11.4 months, respectively. CONCLUSION: Mebendazole was safe and well tolerated when administered with bevacizumab and irinotecan at doses up to 200 mg/kg/day. Further studies are needed to determine the efficacy of this treatment.

A comprehensive strategy to address shortage of Erwinia asparaginase in pediatric acute lymphoblastic leukemia.

BACKGROUND: Pegylated form of E. coli derived asparaginase (PEG) is a crucial component of pediatric ALL therapy. Patients who develop a hypersensitivity (HSR) reaction with PEG receive an alternative form - Erwinia asparaginase (EA). However, an international shortage in 2017 had made it challenging to treat these patients. We have developed a comprehensive strategy to address this need. PATIENTS AND METHODS: This is a single center, retrospective analysis. All patients receiving PEG were premedicated to reduce infusion reactions. Patients who developed HSR underwent PEG desensitization. Patients were compared to historic controls. RESULTS: Fifty-six patients were treated within the study period. There was no difference in the frequency of reactions before and after the adoption of universal premedication (p = 0.78). Eight patients (14.2%) developed either ≥ Grade 2 HSR or silent inactivation and 5 patients (62.5%) successfully underwent desensitization. The remaining three patients received EA asparaginase. This intervention led to a decrease in PEG substitution, with 3 patients (5.3%) requiring EA compared to 8 patients (15.09%) in the pre-intervention period. (p = 0.11) PEG desensitization was more cost effective than EA administration. CONCLUSION: PEG desensitization is a safe, cost effective, and practical alternative in children with ALL and a Grade 2 or higher HSR.

A phase I trial of lenalidomide and radiotherapy in children with diffuse intrinsic pontine gliomas or high-grade gliomas.

PURPOSE: This study was performed to determine the maximum tolerated dose (MTD) or recommended phase 2 dose (RP2D) of the immunomodulatory agent, lenalidomide, when administered daily during 6 weeks of radiation therapy to children with newly diagnosed diffuse intrinsic pontine glioma (DIPG) or high-grade glioma (HGG) PATIENTS & METHODS: Children and young adults < 22 years of age with newly diagnosed disease and no prior chemotherapy or radiation therapy were eligible. Children with HGG were required to have an inoperable or incompletely resected tumor. Eligible patients received standard radiation therapy to a prescription dose of 54-59.4 Gy, with concurrent administration of lenalidomide daily during radiation therapy in a standard 3 + 3 Phase I dose escalation design. Following completion of radiation therapy, patients had a 2-week break followed by maintenance lenalidomide at 116 mg/m2/day × 21 days of a 28-day cycle. RESULTS: Twenty-nine patients (age range 4-19 years) were enrolled; 24 were evaluable for dose finding (DIPG, n = 13; HGG, n = 11). The MTD was not reached at doses of lenalidomide up to 116 mg/m2/day. Exceptional responses were noted in DIPG and malignant glioma (gliomatosis cerebri) notably at higher dose levels and at higher steady state plasma concentrations. The primary toxicity was myelosuppression. CONCLUSION: The RP2D of lenalidomide administered daily during radiation therapy is 116 mg/m2/day. Children with malignant gliomas tolerate much higher doses of lenalidomide during radiation therapy compared to adults. This finding is critical as activity was observed primarily at higher dose levels suggesting a dose response.

Excellent outcome of young children with nodular desmoplastic medulloblastoma treated on "Head Start" III: a multi-institutional, prospective clinical trial.

BACKGROUND: "Head Start" III, was a prospective clinical trial using intensive induction followed by myeloablative chemotherapy and autologous hematopoietic cell rescue (AuHCR) to either avoid or reduce the dose/volume of irradiation in young children with medulloblastoma. METHODS: Following surgery, patients received 5 cycles of induction followed by myeloablative chemotherapy using carboplatin, thiotepa, and etoposide with AuHCR. Irradiation was reserved for children >6 years old at diagnosis or with residual tumor post-induction. RESULTS: Between 2003 and 2009, 92 children <10 years old with medulloblastoma were enrolled. Five-year event-free survival (EFS) and overall survival (OS) rates (±SE) were 46 ±â€…5% and 62 ±â€…5% for all patients, 61 ±â€…8% and 77 ±â€…7% for localized medulloblastoma, and 35 ±â€…7% and 52 ±â€…7% for disseminated patients. Nodular/desmoplastic (ND) medulloblastoma patients had 5-year EFS and OS (±SE) rates of 89 ±â€…6% and 89 ±â€…6% compared with 26 ±â€…6% and 53 ±â€…7% for classic and 38 ±â€…13% and 46 ±â€…14% for large-cell/anaplastic (LCA) medulloblastoma, respectively. In multivariate Cox regression analysis, histology was the only significant independent predictor of EFS after adjusting for stage, extent of resection, regimen, age, and sex (P <0.0001). Five-year irradiation-free EFS was 78 ±â€…8% for ND and 21 ±â€…5% for classic/LCA medulloblastoma patients. Myelosuppression was the most common toxicity, with 2 toxic deaths. Twenty-four survivors completed neurocognitive evaluation at a mean of 4.9 years post-diagnosis. IQ and memory scores were within average range overall, whereas processing speed and adaptive functioning were low-average. CONCLUSION: We report excellent survival and preservation of mean IQ and memory for young children with ND medulloblastoma using high-dose chemotherapy, with most patients surviving without irradiation.

Delivering Challenging News: An Illness-Trajectory Communication Curriculum for Multispecialty Oncology Residents and Fellows.

Introduction: Published curricula to teach communication skills for postgraduate fellows in oncology are few in number despite the fact that oncologists conduct many difficult discussions with their patients and their families. Such discussions may include disclosing initial diagnosis or relapse of a patient's cancer or relaying a poor prognosis or change to palliative care. Methods: An eight-module course on communication in oncology practice was delivered over 2 months for palliative and oncology fellows and radiation oncology residents. Learners were given a precourse survey in which they were asked to rate their proficiency in various communication tasks. Each learner then participated in a videotaped precourse objective structured clinical exam (OSCE) on breaking bad news with standardized patients (SPs). The course took place over 8 weeks with weekly didactics and role-play. At the end of the course, a second OSCE took place. After the course was completed, the fellows again filled out a proficiency survey. Results: Twenty-two learners participated over 2 years of this course. Participants reported a significant increase in perceived competence in all areas on the postcourse survey. SP feedback on OSCEs pre- and postcourse indicated improvement in skills for learners. Pre- and postcourse OSCE video assessment revealed a significant improvement in global communication skills. Discussion: Initial data show that this course successfully improved communication skills and increased fellows' comfort level across several domains of communication. Future directions include validating our assessment tool, expanding the topic base, and investigating the impact on practice after course completion.

Repurposing Mebendazole as a Replacement for Vincristine for the Treatment of Brain Tumors.

The microtubule inhibitor vincristine is currently used to treat a variety of brain tumors, including low-grade glioma and anaplastic oligodendroglioma. Vincristine, however, does not penetrate well into brain tumor tissue, and moreover, it displays dose-limiting toxicities, including peripheral neuropathy. Mebendazole, a Food and Drug Administration-approved anthelmintic drug with a favorable safety profile, has recently been shown to display strong therapeutic efficacy in animal models of both glioma and medulloblastoma. Importantly, appropriate formulations of mebendazole yield therapeutically effective concentrations in the brain. Mebendazole has been shown to inhibit microtubule formation, but it is not known whether its potency against tumor cells is mediated by this inhibitory effect. To investigate this, we examined the effects of mebendazole on GL261 glioblastoma cell viability, microtubule polymerization and metaphase arrest, and found that the effective concentrations to inhibit these functions are very similar. In addition, using mebendazole as a seed for the National Cancer Institute (NCI) COMPARE program revealed that the top-scoring drugs were highly enriched in microtubule-targeting drugs. Taken together, these results indicate that the cell toxicity of mebendazole is indeed caused by inhibiting microtubule formation. We also compared the therapeutic efficacy of mebendazole and vincristine against GL261 orthotopic tumors. We found that mebendazole showed a significant increase in animal survival time, whereas vincristine, even at a dose close to its maximum tolerated dose, failed to show any efficacy. In conclusion, our results strongly support the clinical use of mebendazole as a replacement for vincristine for the treatment of brain tumors.

Humanism and professionalism education for pediatric hematology-oncology fellows: A model for pediatric subspecialty training.

BACKGROUND: Humanism and professionalism are virtues intrinsic to the practice of medicine, for which we lack a standard, evidence-based approach for teaching and evaluation. Pediatric hematology-oncology (PHO) fellowship training brings new and significant stressors, making it an attractive setting for innovation in humanism and professionalism training. PROCEDURE: We electronically surveyed a national sample of PHO fellows to identify fellows' educational needs in humanism and professionalism. Next, we developed a case-based, faculty-facilitated discussion curriculum to teach this content within pilot fellowship programs. We assessed whether fellowships would decide to offer the curriculum, feasibility of administering the curriculum, and satisfaction of fellow and faculty participants. RESULTS: Surveys were completed by 187 fellows (35%). A minority (29%) reported that their training program offers a formal curriculum in humanism and/or professionalism. A majority desires more formal teaching on balancing clinical practice and research (85%), coping with death/dying (85%), bereavement (78%), balancing work and personal life (75%), navigating challenging relationships with patients (74%), and depression/burn out (71%). These six topics were condensed into four case-based modules, which proved feasible to deliver at all pilot sites. Ten fellowship programs agreed to administer the novel curriculum. The majority (90%) of responding fellows and faculty reported the sessions touched on issues important for training, stimulated reflective communication, and were valuable. CONCLUSIONS: Pediatric hematology-oncology fellows identify numerous gaps in their training related to humanism and professionalism. This curriculum offers an opportunity to systematically address these educational needs and can serve as a model for wider implementation.

Intensive induction chemotherapy followed by myeloablative chemotherapy with autologous hematopoietic progenitor cell rescue for young children newly-diagnosed with central nervous system atypical teratoid/rhabdoid tumors: the Head Start III experience.

BACKGROUND: Atypical teratoid/rhabdoid tumor (AT/RT) of the central nervous system (CNS) is a rare embryonal neoplasm of early childhood with dismal outcome and no current uniformly accepted treatment. Given its highly aggressive nature and predilection for dissemination at diagnosis, intensive multimodal therapy is required. MATERIALS AND METHODS: Nineteen children with newly diagnosed CNS AT/RT were treated on the head start (HS) III protocol. Treatment consisted of surgical resection, 5 cycles of induction chemotherapy, followed by consolidation with myeloablative chemotherapy and autologous hematopoietic progenitor cell rescue (AuHCR). Irradiation was given following recovery from consolidation based on patient age, disease extent at diagnosis, and treatment response to induction. RESULTS: Nineteen children (median age of 14 months) were treated on HS III between 2003 and 2009. Only four finished induction and three proceeded to consolidation. There are presently four survivors at 40, 42, 46, and 79 months from study enrollment. Eleven patients experienced tumor progression at a median time to progression of 4.1 months of whom 10 died with a median time from progression to death of 2.6 months. Five toxic deaths occurred, three of them while on the study. The 3-year event-free survival (EFS) and overall survival (OS) for the whole group was 21 ± 9% and 26 ± 10%, respectively. Five patients received irradiation at progression with only one long-term survivor. CONCLUSION: A minority of children with CNS AT/RT treated on HS III may be long-term survivors without irradiation. More effective therapies are desperately needed.

Outcome of infants and young children with newly diagnosed ependymoma treated on the "Head Start" III prospective clinical trial.

This study investigates the outcome of children <10 years old with newly-diagnosed ependymoma treated on the prospective multinational "Head Start" III clinical trial. Between April 2004 and July 2009, 19 children with newly-diagnosed ependymoma were enrolled. All children were to receive five induction chemotherapy cycles followed by one consolidation cycle of myelo-ablative chemotherapy and autologous hematopoietic cell rescue. Children between 6 and 10 years of age or with residual tumor prior to consolidation were to receive irradiation thereafter. Median age of 19 children (8 female) was 20 months at diagnosis. Median follow up was 44 months. The primary site was infratentorial in 11 and supratentorial in 8 patients. Gross total resection was achieved in 10 patients. After induction chemotherapy, all three supratentorial ependymoma patients with residual disease achieved a complete response (CR), while only one of six infratentorial patients with residual disease achieved CR. Three infratentorial patients developed progressive disease during induction chemotherapy. All four infratentorial patients with residual disease who underwent autologous hematopoietic cell transplant, failed to achieve CR. Four patients received focal irradiation following chemotherapy. The 3-year event free survival (EFS) and overall survival (OS) for supratentorial ependymoma were 86 ± 13 % and 100 % respectively. The 3-year EFS and OS for infratentorial ependymoma were 27 ± 13 % and 73 ± 13 % respectively. The role of intensive induction and consolidation chemotherapy in deferring irradiation should be investigated further in children with supratentorial ependymoma with residual disease following surgery. This approach appears ineffective in children with infratentorial ependymoma in the absence of irradiation.

Tumor necrosis factor-alpha gene polymorphisms are associated with severity of acute graft-versus-host disease following matched unrelated donor bone marrow transplantation in children: a Pediatric Blood and Marrow Transplant Consortium study.

Tumor necrosis factor (TNF)-alpha plays a significant role in conditioning related toxicities and the development of acute graft-versus-host disease (aGVHD). TNF-alpha gene polymorphisms are associated with rejection after organ transplantation and aGVHD in matched related donor blood and marrow transplantation (BMT) recipients. Few studies have been published on unrelated donor BMT in the pediatric age group. In this study, we examined the relationship between specific polymorphisms in TNF pathway genes and the occurrence and severity of aGVHD. Recipient single-nucleotide polymorphisms (SNPs) in TNF-alpha and TNF receptor superfamily members 1A (TNFRSF1A) and 1B (TNFRSF1B) were investigated. In a multi-institutional Pediatric Blood and Marrow Transplant Consortium trial, a total of 180 pediatric patients (mean age, 11.0 years) were prospectively evaluated for clinical outcomes after matched unrelated donor BMT. All patients received myeloablative conditioning and two-drug GVHD prophylaxis with cyclosporine or tacrolimus, with methotrexate in the majority of patients. TNF-alpha genotypes were not correlated with the overall incidence of aGVHD. Significant associations were seen between TNF-alpha variant alleles and the severity of aGVHD (grade II-IV and grade III-IV), especially when analyzed in whites only (n = 165). Grade II-IV aGVHD was correlated with recipient -857T allele (hazard ratio [HR], 0.47; P = .04), -238A allele (HR, 1.76; P = .002), and d3/d3 genotype (HR, 0.64; P = .03). Severe (grade III-IV) aGVHD was associated with TNF-alpha -1031C allele (HR, 2.38; P = .03), -863A allele (HR, 3.18; P = .003), and d4/d4 genotype (HR, 2.82; P = .01). After adjusting for clinical factors, the association of -1031C, -863A, -238A, and d4/d4 genotypes with severity of aGVHD remained statistically significant. No correlation between selected SNPs in TNFRSF1A or TNFRSF1B and the incidence or severity of aGVHD was found. Our findings indicate clinically important relationships between genetic polymorphisms in TNF-alpha and the severity of aGVHD in this cohort. Improved understanding of this relationship may allow for a risk-adjusted approach to GVHD prevention in pediatric BMT.

Low incidence of hepatic veno-occlusive disease in pediatric patients undergoing hematopoietic stem cell transplantation attributed to a combination of intravenous heparin, oral glutamine, and ursodiol at a single transplant institution.

We report the low incidence of hepatic VOD in pediatric patients with various diagnoses including hematologic malignancies and non-malignant conditions transplanted at our institution. Retrospective review of 188 patients who underwent HSCT and received a combined prophylactic regimen of intravenous heparin, oral glutamine, and ursodiol was undertaken. Analysis of the outcome of VOD revealed only one clinical case with acute myeloid leukemia; the patient developed hepatic VOD 10 days after receiving myeloablative chemotherapy with busulfan and CTX followed by HLA-matched related peripheral blood stem cell transplantation. The low incidence of hepatic VOD in an otherwise high-risk pediatric transplant population is an important observation, which may be partly attributed to this prophylactic regimen, and warrants further randomized clinical trials for confirmation.

Transient myeloproliferative disorder in neonates with and without Down syndrome: a tale of 2 syndromes.

Transient myeloproliferative disorder (TMD) in newborns with Down syndrome (DS) has been well described. We report 4 newborns, 2 with DS and 2 without DS, who developed TMD. One newborn with DS developed multiorgan failure and died despite treatment with low-dose cytarabine. In 3 newborns, the TMD resolved spontaneously. Two of these patients, 1 with and 1 without DS developed leukemia on subsequent follow-up and were treated successfully. We reviewed the clinical and laboratory data on 14 non-DS infants with TMD reported in the literature. According to limited data, these patients are more likely to develop leukemia than DS patients, however their outcome is better.

Brainstem primitive neuroectodermal tumors (bstPNET): results of treatment with intensive induction chemotherapy followed by consolidative chemotherapy with autologous hematopoietic cell rescue.

We have evaluated the response rate and survival utilizing intensified chemotherapy followed by myeloablative chemotherapy with autologous hematopoietic cell rescue (AuHCR) and adjuvant radiation therapy in six young children with newly diagnosed brainstem primitive neuroectodermal tumors (bstPNET). Following maximum surgical resection of the tumor, patients received high dose induction chemotherapy including vincristine, cisplatin, cyclophosphamide, and etoposide. Eligible patients received a single cycle of myeloablative chemotherapy followed by AuHCR. Two patients survive at least 32 months with stable disease. This approach provides an alternative for young patients with bstPNET who in prior reports have had a uniformly fatal prognosis.

PER pressure: New Jersey's "Population Emissions Ratio" environmental equity screening model.

In recent years, much attention has focused on how to incorporate environmental equity considerations into government permitting programs for environmentally regulated facilities. On February 4, 2002, the New Jersey Department of Environmental Protection (NJDEP) became the first state environmental agency to propose a broad legally binding rule intended to guard against environmental inequity in its permitting decisions. The proposed rule centered on an innovative computerized environmental equity (EE) screening model that used "Population Emissions Ratios" to identify small geographic areas in which environmental equity concerns might exist and to simulate the effect on statewide environmental equity of increasing environmental risks in small geographic areas. The NJDEP's model examined an extensive array of ethnic groups, included a variety of environmental risks, evaluated most of those risks in terms of human health, and used an innovative simulation process designed to identify permitting decisions that would worsen statewide environmental inequity. The results of the NJDEP's efforts, however, pose substantial concerns. For example, some key provisions of the NJDEP's model were inadequately explained and some were illogical and would bias its results. The model might be susceptible to generating implausible results due to small, meaningless, and/or essentially random fluctuations in its data inputs. The model used relatively large geographic areas as the units of analysis and interpolated results between them, rather than using smaller geographic areas and avoiding interpolation errors. Finally, the environmental risks evaluated by the model were both arguably over- and underinclusive. Thus, the NJDEP's efforts, although noteworthy, raised more issues than they settled.
