The Ethical Complexity of Medical Decision Making in the Adolescent Oncology Patient.

Adolescent Medical Decision Making (aMDM) is frequently discussed but presents a significant challenge in practice, especially in cases of adolescents with life threatening or life limiting illnesses. In this paper, we present a case that explores the importance of aMDM, the difficulties for providers when engaging adolescents in these discussions, and how certain skills may be incorporated into pediatric practice. Literature suggests that patients of this age group, while being legally without capacity, have meaningful insights into their care. However, unless physicians feel comfortable and competent engaging adolescents in a manner that honors their developmentally appropriate understanding of their illness, these insights can be lost.

Implementing Rounding Checklists in a Pediatric Oncologic Intensive Care Unit.

Standardized rounding checklists during multidisciplinary rounds (MDR) can reduce medical errors and decrease length of pediatric intensive care unit (PICU) and hospital stay. We added a standardized process for MDR in our oncologic PICU. Our study was a quality improvement initiative, utilizing a four-stage Plan-Do-Study-Act (PDSA) model to standardize MDR in our PICU over 3 months, from January 2020 to March 2020. We distributed surveys to PICU RNs to assess their understanding regarding communication during MDR. We created a standardized rounding checklist that addressed key elements during MDR. Safety event reports before and after implementation of our initiative were retrospectively reviewed to assess our initiative's impact on safety events. Our intervention increased standardization of PICU MDR from 0% to 70% over three months, from January 2020 to March 2020. We sustained a rate of zero for CLABSI, CAUTI, and VAP during the 12-month period prior to, during, and post-intervention. Implementation of a standardized rounding checklist may improve closed-loop communication amongst the healthcare team, facilitate dialogue between patients' families and the healthcare team, and reduce safety events. Additional staffing for resource RNs, who assist with high acuity patients, has also facilitated bedside RN participation in MDR, without interruptions in clinical care.

Addressing Common Pain Syndromes in Pediatric Stem Cell Transplant: A Review.

Assessment and management of pain for pediatric patients receiving stem cell transplants can be challenging for a health care team. Diagnostic evaluation and interventions vary between institutions and individual provider practices. In this review, we investigate and describe approaches to pain management for the most common sources of pain in pediatric patients undergoing stem cell transplants. Mucositis pain, abdominal pain, and hemorrhagic cystitis emerged as the most frequent sources of acute pain in children during conditioning and transplantation periods. Furthermore, psychosocial distress and psychological pain or distress constitute significant components of the total pain experienced by children undergoing stem cell transplantation. We will expand upon appropriate usage and escalation of opioids, as well as complementary interventions and timely initiation of interventions, in order to help control pain in these clinical syndromes.

Chimeric Antigen Receptor, Teamwork, Education, Assessment, and Management (CAR-TEAM): A Simulation-Based Inter-professional Education (IPE) Intervention for Management of CAR Toxicities.

Chimeric antigen receptor (CAR) therapies such as tisagenlecleucel, indicated for children and young adults with relapsed and/or refractory CD19+ acute lymphoblastic leukemia (ALL), have been associated with striking treatment outcomes and overall survival. Yet, they are also associated with unique and potentially life-threatening complications. Cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity (ICANS) are generally reversible complications of CAR therapies, but many patients may require critical care support especially if they are not promptly recognized and appropriately managed by frontline healthcare staff. As CAR therapies become more widely available, it is important that inter-professional staff members be aware of general principles regarding diagnosis and management. We hypothesized that an inter-professional education (IPE) simulation-based education intervention (CAR-TEAM) would improve knowledge base and confidence regarding complications of CAR therapies among inter-professional staff. Here, we demonstrate that following CAR-TEAM training, >90% of participants demonstrated knowledge proficiency and confidence in the IPE content area. CAR-TEAM training may serve as an important tool to establish initial and continued competency among sites introducing CAR therapies.

Modulating sphingosine-1-phosphate receptors to improve chemotherapy efficacy against Ewing sarcoma.

Tumor vasculature is innately dysfunctional. Poorly functional tumor vessels inefficiently deliver chemotherapy to tumor cells; vessel hyper-permeability promotes chemotherapy delivery primarily to a tumor's periphery. Here, we identify a method for enhancing chemotherapy efficacy in Ewing sarcoma (ES) in mice by modulating tumor vessel permeability. Vessel permeability is partially controlled by the G protein-coupled Sphinosine-1-phosphate receptors 1 and 2 (S1PR1 and S1PR2) on endothelial cells. S1PR1 promotes endothelial cell junction integrity while S1PR2 destabilizes it. We hypothesize that an imbalance of S1PR1:S1PR2 is partially responsible for the dysfunctional vascular phenotype characteristic of ES and that by altering the balance in favor of S1PR1, ES vessel hyper-permeability can be reversed. In our study, we demonstrate that pharmacologic activation of S1PR1 by SEW2871 or inhibition of S1PR2 by JTE-013 caused more organized, mature and functional tumor vessels. Importantly, S1PR1 activation or S1PR2 inhibition improved antitumor efficacy. Our data suggests that pharmacologic targeting of S1PR1 and S1PR2 may be a useful adjuvant to standard chemotherapy for ES patients.

Diagnosis, grading, and treatment recommendations for children, adolescents, and young adults with sinusoidal obstructive syndrome: an international expert position statement.

Sinusoidal obstructive syndrome, also known as hepatic veno-occlusive disease, is a potentially life-threatening complication that occurs in children undergoing haemopoietic stem-cell transplantation (HSCT). Differences in the incidence of genetic predisposition and clinical presentation of sinusoidal obstructive syndrome between children and adults have rendered the historical Baltimore and Seattle diagnostic criteria insufficient for children. In 2017, the European Society for Blood and Marrow Transplantation (EBMT) proposed the first paediatric diagnostic and severity grading guidelines for sinusoidal obstructive syndrome, intended for implementation across European centres. However, universally accepted paediatric criteria are needed to ensure prompt diagnosis, definitive treatment, and improved outcomes for children, adolescents, and young adults with sinusoidal obstructive syndrome, and to facilitate international clinical research collaboration. We convened an international panel of multidisciplinary experts including physicians with expertise in HSCT, paediatric intensive care, nephrology, hepatology, radiology, pathology, and transfusion medicine; HSCT advanced-practice providers and medical trainees; pharmacists; and translational and basic science researchers from the Pediatric Acute Lung Injury and Sepsis Investigators Network, the EBMT, the Pediatric Blood and Marrow Transplant Consortia, and several other institutions with extensive experience in sinusoidal obstructive syndrome. Panellists convened at The University of Texas, MD Anderson Cancer Center (Houston, TX, USA) in February, 2019, to evaluate the available evidence. In this expert position statement paper, we provide consensus recommendations for the international implementation of guidelines for the diagnosis, severity grading, and treatment of sinusoidal obstructive syndrome among children, adolescents, and young adults. We endorse universal adoption of paediatric diagnostic guidelines for sinusoidal obstruction syndrome as proposed by the EBMT, and provide implementation guidance for standardisation across centres; we have further proposed adjunctive use of age-appropriate organ-specific toxicity criteria for severity grading and provided prophylaxis and treatment considerations among children and adolescent and young adult patients. Key recommendations include: (1) liver biopsy, portal venous wedge pressure, and reversal of portal venous flow on Doppler ultrasonography should not be used for the routine diagnosis of sinusoidal obstructive syndrome in children, adolescents, and young adults; (2) platelet refractoriness can be defined as a corrected count increment of less than 5000-7500 following at least two sequential ABO-compatible fresh platelet transfusions; (3) hepatomegaly is best defined as an absolute increase of at least 1 cm in liver length at the midclavicular line; and if a baseline measurement is not available, hepatomegaly can be defined as greater than 2 SDs above normal for age; and (4) the presence and volume of ascites can be categorised as mild (minimal fluid by liver, spleen, or pelvis), moderate (<1 cm fluid), or severe (fluid in all three regions with >1 cm fluid in at least two regions).

Pediatric patient with end-stage kidney disease secondary to Eagle-Barrett syndrome and metastatic unresectable hepatoblastoma treated successfully with chemotherapy and liver-kidney transplant.

HBL is the most common malignant liver neoplasm in children. The etiology of HBL is largely unknown but there are certain syndromes, such as Beckwith-Wiedemann syndrome, that have been clearly associated with an increased incidence of this malignancy. EBS, also known as prune belly syndrome, is a congenital anomaly characterized by lax abdominal musculature, bilateral cryptorchidism requiring, in some cases, hemodialysis due to significant kidney and urinary tract dysfunctions. Despite an improvement on the survival rates of patients with advanced-stage HBL, the presence of concomitant end-stage renal disease that occurs in patients with EBS constitutes a therapeutic challenge for the clinician not only due to the use of nephrotoxic chemotherapy but also due to the potential need for multi-organ transplant. We report case of a 2-year-old male patient with EBS diagnosed with stage IV, metastatic HBL successfully treated with multi-agent chemotherapy while on dialysis whom then underwent a simultaneous liver-kidney transplant followed by adjuvant chemotherapy. Ultimately, the patient achieved cancer remission with normalization of his renal function. Our report emphasizes that patients with HBL in the setting of EBS will not only require careful kidney function monitoring while receiving chemotherapy, but they might also need to undergo multi-organ transplantation in order to achieve adequate cancer control and also normalization of their kidney function. Awareness of this unusual association calls for further investigation to potentially establish a genetic association between these two disease processes.
