Nucci AM, Bashaw H, Kirpich A, Rudolph J. Retrospective review of growth in pediatric intestinal failure after weaning from parenteral nutrition. Nutr Clin Pract 2024. [PMID: 39263924 DOI: 10.1002/ncp.11209] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2023] [Revised: 08/14/2024] [Accepted: 08/19/2024] [Indexed: 09/13/2024] Open
Abstract
BACKGROUND Growth outcomes in children with intestinal failure (IF) after weaning from parenteral nutrition (PN) may be modified by primary diagnosis and interventions aimed at achieving enteral tolerance. We evaluated growth after weaning by diagnosis and intestinal transplant status and during treatment with the glucagon-like peptide-2 analog teduglutide. METHODS A two-center retrospective review was conducted on children diagnosed with IF at age <12 months. The z scores for weight and length/height were examined up to 5 years after PN weaning and in children who received teduglutide for >6 months. Data were reported as median and interquartile range (IQR). RESULTS A total of 362 children (58% male and 72% White) were reviewed; 41% (n = 150) weaned from PN at age 1.5 years (IQR = 0.96-3). Weight and length/height data were available for 144 children; 46 received an intestinal transplant. Median weight and length/height z scores at weaning were -1.15 (IQR = -2.09 to -0.39) and -1.89 (IQR = -2.9 to -1.02), respectively. In those not transplanted, z scores remained stable (± 0.5 change). Children with small bowel atresia experienced accelerated linear growth (> +0.5 change) beginning in year 3. Most children transplanted experienced growth acceleration beginning in year 2. Fourteen children received teduglutide (median = 840 [IQR = 425-1530] days), and growth remained stable throughout treatment. Five were weaned from PN within 1 year. CONCLUSION We observed stable growth with limited catch-up after PN weaning, with minimal variation by diagnosis, and during teduglutide therapy. Children who received an intestinal transplant experienced acceleration in weight and linear growth after weaning.

Abstract
Outcomes in intestinal transplantation remain hampered by higher rates of rejection than any other solid organs. However, maintenance immunosuppression regimens have largely remained unchanged despite advances in therapies for induction and treatment of rejection and graft-versus-host disease. Recently, there have been a small number of new maintenance therapies attempted, and older agents have been used in new ways to achieve better outcomes. The authors herein review the traditional maintenance therapies and their mechanisms and then consider updates in new therapies and new ways of using old therapies for maintenance immunosuppression after intestinal transplantation.

Abstract
Advances in immunosuppression have extended patient and graft survival rates after solid organ transplantation; however, this is not free of side effects. Balancing safety and efficacy is of paramount importance, particularly in the pediatric setting. Current literature comparing different protocols is scarce, and decisions are mostly guided by physician preference. We aimed to compare 3 different protocols from 4 different centers to identify differences in outcomes after 1 year of follow-up. A retrospective analysis of the databases of the participating centers was performed. Consecutive patients aged <18 years with a first liver-only transplant and no other underlying congenital or acquired immunodeficiency were included. Patients were classified according to the immunosuppression protocol as follows: group A (prednisone + tacrolimus + basiliximab), group B (prednisone + tacrolimus + basiliximab + antithymocyte globulin), and group C (prednisone + tacrolimus). Differences in survival, frequency of rejection, infections, and other complications were analyzed in the entire group (n = 97) and the group with biliary atresia (n = 48). After 1 year of follow-up, no differences in patient or graft survival were observed when comparing either the entire group (n = 97) or patients with biliary atresia only (n = 48). The frequencies of rejection and episodes of infection were similar. Renal function showed no differences either before or after transplantation or between the groups. Immunosuppression protocols used in this study appeared to be equally safe and effective. This could offer the opportunity to tailor them to the patient's individual characteristics without compromising the outcome.

Abstract
Solid organ transplantation (SOT) is considered the optimal treatment for children with end-stage organ failure; however, increased efforts are needed to understand the gap surrounding equitable access to and health outcomes of SOT for Indigenous children. This scoping review summarizes the literature on the characteristics of access to and health outcomes of pediatric SOT among Indigenous children in the settler-colonial states of Canada, Aotearoa New Zealand, Australia, and the United States. A search was performed on MEDLINE, EMBASE, PsycINFO, and CINAHL for studies matching preestablished eligibility criteria from inception to November 2021. A preliminary gray literature search was also conducted. Twenty-four studies published between 1996 and 2021 were included. Studies addressed Indigenous pediatric populations within the United States (n = 7), Canada (n = 6), Aotearoa New Zealand (n = 5), Australia (n = 5), and Aotearoa New Zealand and Australia combined (n = 1). Findings showed that Indigenous children experienced longer time on dialysis, lower rates of preemptive and living donor kidney transplantation, and disparities in patient and graft outcomes after kidney transplantation. There were mixed findings about access to liver transplantation for Indigenous children and comparable findings for graft and patient outcomes after liver transplantation. Social determinants of health, such as geographic remoteness, lack of living donors, and traditional spiritual beliefs, may affect SOT access and outcomes for Indigenous children. Evidence gaps emphasize the need for action-based initiatives within SOT that prioritize research with and for Indigenous pediatric populations. Future research should include community-engaged methodologies, situated within local community contexts, to inform culturally safe care for Indigenous children.

Abstract
The incidence of pediatric solid organ transplantation (SOT) has increased in recent decades due to medical and surgical advances as well as improvements in organ procurement. Survival rates for pediatric kidney, liver, and heart transplantation are above 85% but patients continue to experience complex healthcare needs over their lifetime. Long-term developmental and neuropsychological sequelae are becoming increasingly recognized in this population, although preliminary work is limited and deserves further attention. Neuropsychological weaknesses are often present prior to transplantation and may be related to underlying congenital conditions as well as downstream impact of the indicating organ dysfunction on the central nervous system. Neuropsychological difficulties pose risk for functional complications, including disruption to adaptive skill development, social-emotional functioning, quality of life, and transition to adulthood. The impact of cognitive dysfunction on health management activities (e.g., medication adherence, medical decision-making) is also an important consideration given these patients' lifelong medical needs. The primary aim of this paper is to provide preliminary guidelines and clinical strategies for assessment of neuropsychological outcomes across SOT populations for pediatric neuropsychologists and the multidisciplinary medical team, including detailing unique and shared etiologies and risk factors for impairment across organ types, and functional implications. Recommendations for clinical neuropsychological monitoring as well as multidisciplinary collaboration within pediatric SOT teams are also provided.

Abstract
BACKGROUND Adolescence is a developmental period that is known for the highest risk of difficulties with adoption and maintenance of health behaviors for successful transplant. Motivational interviewing (MI) has been demonstrated to be an effective strategy in the management of modifiable factors impacting adherence in both adult transplant and analogous pediatric chronic illness populations. AIMS This paper describes MI and its applicability to adolescent transplant, providing examples of its potential use at each stage of the transplant journey. MATERIALS AND METHODS Literature on the principles and utilization of MI are reviewed, as well as the use of MI in adult transplant and similar pediatric populations. RESULTS Evidence suggests high applicability of concepts of MI to pediatric transplant. DISCUSSION Systems-level factors influencing health behavior change are discussed, along with the importance of recognizing and managing provider bias in MI-based interactions. MI does not require a licensed behavioral health provider to use it effectively; rather, it can be used by various multidisciplinary team members throughout the course of clinical care. CONCLUSION MI shows great promise as a useful intervention through all stages in the transplant journey. Though particularly well-suited to adolescents, its principles are effective across the lifespan, including with caregivers. It represents an interactional style for use by multidisciplinary team members in many patient-and caregiver-facing scenarios. As the goal is to support the patient's autonomy in decision-making, it is important for providers to recognize their own biases. Further resources for training are provided.

Abstract
Enteral autonomy is the primary goal of intestinal failure therapy. Intestinal transplantation (ITx) is an option when enteral autonomy cannot be achieved and management complications become life-threatening. The purpose of this review is to summarize existing medical literature related to nutrition requirements, nutrition status, and nutrition support after pediatric ITx. Achieving or maintaining adequate growth after intestinal transplant in children can be challenging because of episodes of rejection that require the use of corticosteroids, occurrences of infection that require a reduction or discontinuation of enteral or parenteral support, and fat malabsorption caused by impaired lymphatic circulation. Nutrient requirements should be assessed and modified regularly based on nutrition status, growth, ventilatory status, wound healing, and the presence of complications. Parenteral nutrition (PN) should be initiated as a continuous infusion early postoperatively. Enteral support should be initiated after evidence of graft bowel function and in the absence of clinical complications. Foods high in simple carbohydrates should be limited, as consumption may result in osmotic diarrhea. Short-term use of a fat-free diet followed by a low-fat diet may reduce the risk of the development of chylous ascites. Micronutrient deficiencies and food allergies are common occurrences after pediatric ITx. Enteral/oral vitamin and mineral supplementation may be required after PN is weaned. Nutrition management of children after ITx can be challenging for all members of the healthcare team. Anthropometric parameters and micronutrient status should be monitored regularly so that interventions to promote growth and prevent or reverse nutrient deficiencies can be implemented promptly.

Abstract
BACKGROUND Education is crucial for pediatric patients and caregivers throughout the transplant continuum, yet data are lacking around which interventions are effective and in what circumstances. METHODS We undertook a scoping review with the objectives of (a) describing the types, effects, and outcomes of patient-focused educational interventions before and after pediatric transplant and (b) understanding the educational experiences of patients and caregivers. Five scientific databases were explored for relevant literature using the JBI methodology. Educational interventions published in English, targeting pediatric solid organ transplant patients (0-25 years) and their caregivers were included. Relevant data from eligible articles (n = 27) were extracted and summarized. RESULTS Eighteen articles describing 17 educational interventions were identified for objective A, and nine articles qualitatively assessing patient or parental learning needs were identified for objective B. Most interventions were directed toward teenage patients and their caregivers post kidney transplant, primarily focusing on medication self-management and adherence, or providing general information on transplant using multicomponent delivery formats. Most interventions achieved statistically significant improvements in knowledge (n = 8/9) and patients or caregivers expressed satisfaction with the intervention (n = 7/7) but health-related outcomes such as medication adherence (n = 2/6) or behavior change (n = 1/3) rarely achieved statistically significant results. In objective B, patients and caregivers described the transplant process as overwhelming, but indicated that social supports and education helped them cope. Participants consistently wanted more information than they received. CONCLUSION Caregivers and pediatric patients value transplant education, but high-quality studies are limited. Since education is a fundamental part of the transplant process, future research in this area should be prioritized.

Abstract
Post-transplant Lymphoproliferative Disease (PTLD) remains a major complication of solid organ transplantation (SOT) in pediatric patients. The majority are Epstein-Barr Virus (EBV) driven CD20+ B-cell proliferations responsive to reduction to immunosuppression and anti-CD20 directed immunotherapy. This review focusses on the epidemiology, role of EBV, clinical presentation, current treatment strategies, adoptive immunotherapy and future research in EBV + PTLD in pediatric patients.

Abstract
OBJECTIVE Solid-organ transplantation (SOT) has become the standard of care for children with terminal organ failure. Long-term immunosuppression has improved survival substantially but is associated with secondary malignancies and impaired wound healing. Our goal was to review the incidence, outcomes, complications, and rate of posttransplant lymphoproliferative disorder on pathologic examination following tonsillectomy/adenotonsillectomy (T/AT) in children after SOT. STUDY DESIGN A retrospective cohort study. SETTING Tertiary care children's hospital. METHODS Data were extracted from charts of children with a history of kidney, heart, or liver transplantation, who underwent T/AT between 2006 and 2021. RESULTS A total of 110 patients met the inclusion criteria, including 46 hearts, 41 kidneys, 19 livers, and 4 liver-and-kidney transplants. The mean age at transplantation was 4.2 years, and the mean transplantation-to-T/AT time interval was 28.8 months. The posttransplant lymphoproliferative disorder was diagnosed in 52 (47.3%) patients, and 25% of these had no tonsillar hypertrophy. There was no difference in age at transplantation, organ received, transplantation-to-T/AT time interval, immunosuppressive medications, tonsil size, or tonsillar asymmetry between patients diagnosed with the posttransplant lymphoproliferative disorder and patients with benign tonsillar/adenotonsillar hypertrophy. Posttonsillectomy complications were similar between the groups. CONCLUSION The incidence of posttransplant lymphoproliferative disorder undergoing tonsillectomy for any indication was 47.3%. There was no association between preoperative signs and symptoms and the histopathological diagnosis of posttransplant lymphoproliferative disorder. Stratification by organ received and immunosuppressive medications did not identify differences among the groups relative to the incidence of posttransplant lymphoproliferative disorder and other postoperative complications.

Düken ME, Zengin M, Yayan EH. The effect of perceived social support on the psychosocial status of parents whose child had liver transplantation. J Pediatr Nurs 2022; 66:e130-e136. [PMID: 35527086 DOI: 10.1016/j.pedn.2022.04.016] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/30/2021] [Revised: 04/19/2022] [Accepted: 04/21/2022] [Indexed: 10/18/2022]
Abstract
BACKGROUND The aim of this study was to describe parental psychosocial outcomes following paediatric liver transplantation and the relationship between parental psychosocial outcomes and social support. METHOD This is a correlational, descriptive study conducted between April 2021 and October 2021 in the paediatric hepatology polyclinics of the liver transplantation institute of a university hospital. The SPSS 25 and AMOS 23 package programmes were used to perform data analyses. RESULTS Data analysis revealed that the parents' social support level was low (44.6 ± 14.8), while their levels of trait anxiety (51.5 ± 4.8) and loneliness (48.5 ± 5.4) were high, and their depression level was moderate (26.4 ± 5.8). Established structural equation modelling demonstrated that the social support parents received had a significant effect on their levels of loneliness (β = -0.88; p < 0.001), trait anxiety (β = -0.37; p < 0.001), and depression (β = -0.44; p < 0.001). CONCLUSION The authors conclude that in parents of children who have had a liver transplant, increased levels of perceived social support result in decreased levels of anxiety, loneliness, and depression. PRACTICE IMPLICATIONS The authors recommend that healthcare professionals can contribute to reducing the anxiety, loneliness and depression in parents of paediatric liver transplant recipients by strengthening their social support systems.

Pediatr Transplant 2022; 26:e14280. [PMID: 35388604 DOI: 10.1111/petr.14280] [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: 05/24/2021] [Revised: 03/15/2022] [Accepted: 03/26/2022] [Indexed: 11/28/2022]
Abstract
BACKGROUND Adolescent and young adult (AYA) solid organ transplant recipients experience worsening medical outcomes during transition to adult healthcare. Current understanding and definitions of transition success emphasize first initiation of appointment attendance in adult healthcare; however, declines in attendance over time after transfer remain possible, particularly as AYAs are further removed from their pediatric provider and assume greater independence in their care. METHODS The current study assessed health-care utilization, medical outcomes, and transition success among 49 AYA heart, kidney, or liver recipients recently transferred to adult healthcare. Differences in outcomes were examined along two transition success criteria: (1) initial engagement in adult healthcare within 6 or 12 months of last pediatric appointment and (2) retention in adult healthcare over 3 years following last pediatric appointment. Growth curve modeling examined change in attendance over time. RESULTS Successful retention in adult healthcare was significantly related to more improved clinical outcomes, including decreased number and duration of hospitalizations and greater medication adherence, as compared to initial engagement. Significant declines in appointment attendance over 3 years were noted, and individual differences in declines were not accounted for by age at transfer or time since transplant. CONCLUSIONS Findings underscore support for AYAs after transfer, as significant declines in attendance were noted after initiating adult care. Clinical care teams should examine transition success longitudinally to address changes in health-care utilization and medical outcomes. Attention to interventions and administrative support aimed at maintaining or increasing attendance and identifying risk factors and intervention for unsuccessful transition is warranted.

Abstract
Kidney transplantation is the best health option for patients with end-stage kidney disease. Ideally, a kidney transplant would last for the lifetime of each recipient. However, depending on the age of the recipient and details of the kidney transplant, there may be a need for a second, third, fourth, or even more kidney transplants. In this overview, the outcome of multiple kidney transplants for an individual is presented. Key issues include surgical approach and immunologic concerns. Included in the surgical approach is an analysis of transplant nephrectomy, with indications, timing, and immunologic impact. Allograft thrombosis, whether related to donor or recipient factors merits investigation to prevent it from happening again. Other posttransplant events such as rejection, viral illness (polyomavirus hominis type I), recurrent disease (focal segmental glomerulosclerosis), and posttransplant lymphoproliferative disease may lead to the need for retransplantation. The pediatric recipient is especially likely to need a subsequent kidney transplant. Finally, noncompliance/nonadherence can affect both adults and children. Innovative approaches may reduce the need for retransplantation in the future.

Abstract
More than 80% of pediatric solid organ transplant (SOT) recipients now survive into young adulthood and many encounter transplant-related complications. Post-transplantation diabetes mellitus (PTDM), sometimes also referred to as post-transplant diabetes or new onset diabetes after transplant, occurs in 3-20% of pediatric SOT recipients depending upon the organ transplanted, age at transplantation, immunosuppressive regimen, family history, and time elapsed since transplant. To diagnose PTDM, hyperglycemia must persist beyond the initial hospitalization for transplantation when a patient is on stable doses of immunosuppressive medications. Though standard diagnostic criteria used by the American Diabetes Association (ADA) to diagnose diabetes are employed, clinicians need to be aware of the limitations of using these criteria in this unique patient population. Management of PTDM parallels strategies used for type 2 diabetes (T2D), while also carefully considering comorbidities and potential interactions with immunosuppressive medications in these patients. In caring for patients with PTDM, it is important to be familiar with these interactions and comorbidities in order to coordinate care with the transplant team and optimize outcomes for these patients.

Abstract
BACKGROUND Physical activity (PA) has been shown to have benefits, including improving health-related quality of life (HRQOL). However, there are few and conflicting studies assessing PA and its relationship with HRQOL in a pediatric solid-organ transplant (SOT) population. The aim of this study was to assess whether overall HRQOL was associated with PA and to determine whether that association was independent of other baseline and contemporaneous clinical and demographic indicators. METHODS A retrospective cross-sectional review was performed on 55 pediatric transplant patients (13 heart, 27 kidney, and 15 liver transplant). PA was measured by PAQ-C/PAQ-A, and HRQOL was measured using PedsQL. Demographics, baseline, and contemporaneous data were collected. RESULTS There were no significant differences in baseline and contemporaneous characteristics between heart, kidney, and liver transplant recipients. SOT recipients were 15.0 (11.0-18.0) years old at completion of surveys. Median PAQ score was 2.3 (1.6-3.2), PedsQL total score was 77 (65-91), and PedsQL physical functioning score was 88 (72-97). The PedsQL total score was not significantly associated with PAQ score. The PAQ score was significantly associated with physical functioning subscore of the PedsQL (r = 0.37, p < 0.01). Higher physical functioning score was associated with time since transplant (r = 0.29, p = 0.031). CONCLUSION Our SOT cohort has a HRQOL similar to other chronic conditions and higher than previous reported HRQOL in pediatric SOT populations. Higher levels of PA and longer time since transplant are associated with higher physical functioning scores.

Abstract
OBJECTIVE The COVID-19 pandemic and lockdown measures have had a clear psychological impact on families, and specifically those with children with chronic illnesses have reported greater overloads and exhaustion. The objective of this study was to evaluate the exposure, impact and experience of the pandemic on families of pediatric solid organ transplant (SOT) recipients compared to families of healthy children and adolescents. METHODS We recruited 96 families, 48 with a pediatric SOT recipient and 48 healthy controls, matched by child age and gender. A primary caregiver from each family responded to an online sociodemographic questionnaire and the COVID-19 Exposure and Family Impact Survey (CEFIS), which explores the exposure, impact and experience of the pandemic and lockdown on families. RESULTS Exposure to the pandemic was greater in families of healthy children and adolescents. The impact was mostly negative in both groups: caregivers reported increased anxiety (76%) and mood disturbances (71.9%) and hindered quality of sleep (64.6%) and health habits (58.3%). On the positive side, family relationships improved. Qualitatively, the SOT group positively perceived isolation and established hygienic measures as protective and destigmatizing, although they reported fear of virus transmission to their child. CONCLUSIONS The psychological impact of the pandemic has been similar in both groups, although families of transplant recipients have protected themselves more, probably because they are used to prevention measures and they see contagion as a graver risk. Additionally, SOT recipients' families presented some idiosyncratic elements, especially a decrease in their perception of stigma associated with the medical condition.

Abstract
BACKGROUND Transplantation is a saving therapeutic that has heavy consequences. The quality of life (QoL) of transplanted children and their parents has been little studied and should help physicians better manage these patients. The objectives of the study were to assess: (1) the QoL of transplanted children and parents and compare it with that of children with other chronic conditions associated with long-term consequences, and (2) potential variables modulating the QoL. METHODS This cross-sectional study was performed in a multidisciplinary paediatric unit (Timone Hospital, Marseille, France). Children were less than 18 years old; had a liver, kidney or heart transplant; and had a time since transplantation of 1-10 years. Socio-demographics and clinical data were recorded from medical forms. The QoL was assessed using the VSP-A (Vécu et Santé Perçue de l'Adolescent et de l'Enfant) and the WhoQoL self-reported questionnaires. RESULTS Forty-five families were included (response rate: 76%). The transplanted organs were the liver for 20 children, the kidney for 15 children, and the heart for 10 children. The QoL of transplanted children reported by their parents was better than that of children with inborn errors of metabolism and similar to that of childhood leukaemia survivors. The QoL of parents of transplanted children was better than that of parents of children with inborn errors of metabolism and did not differ from French norms. The QoL did not differ according to the nature of the transplanted organ, sex or the main sociodemographic data. The main modulators decreasing QoL were residual treatment level, medications switch and the presence of another regular treatment. CONCLUSION Transplanted children and their families reported a fairly preserved QoL compared to children with other chronic health conditions. Special attention should be given to QoL modulators related to therapeutic management (medication switches, regular treatments) that might be amenable to improve the QoL.

Abstract
Survival after solid organ transplantation (SOT) is limited by chronic rejection as well as the need for lifelong immunosuppression and its associated toxicities. Several preclinical and clinical studies have tested methods designed to induce transplantation tolerance without lifelong immune suppression. The limited success of these strategies has led to the development of clinical protocols that combine SOT with other approaches, such as allogeneic hematopoietic stem cell transplantation (HSCT). HSCT prior to SOT facilitates engraftment of donor cells that can drive immune tolerance. Recent innovations in graft manipulation strategies and post-HSCT immune therapy provide further advances in promoting tolerance and improving clinical outcomes. In this review, we discuss conventional and unconventional immunological mechanisms underlying the development of immune tolerance in SOT recipients and how they can inform clinical advances. Specifically, we review the most recent mechanistic studies elucidating which immune regulatory cells dampen cytotoxic immune reactivity while fostering a tolerogenic environment. We further discuss how this understanding of regulatory cells can shape graft engineering and other therapeutic strategies to improve long-term outcomes for patients receiving HSCT and SOT.

Abstract
Living with end-stage organ failure is associated with an accumulation of traumatic medical events, and despite recovery after solid-organ transplantation (SOT), many children continue to exhibit lower quality of life (QOL). Few studies have examined the relationship between post-traumatic stress disorder (PTSD) and QOL among pediatric SOT recipients. We conducted a retrospective, cross-sectional review of 61 pediatric SOT recipients (12 heart, 30 kidney, and 19 liver) to evaluate the association of PTSD with self-reported QOL. PTSD was measured by the Child Trauma Screening Questionnaire (CTSQ), and QOL was measured using the PedsQL and PedsQL Transplant Module (PedsQL-TM) surveys. Demographics, baseline, and contemporaneous factors were tested for independent association. SOT recipients were 15.2 (12.1-17.6) years old at survey completion. Median CTSQ score was 2 (1-3), highest in kidney recipients, and 13% were identified as high risk for PTSD. Median PedsQL score was 83 (70-91) and significantly associated with the CTSQ score (r = -.68, p < .001). Median PedsQL Transplant Module score was 89 (83-95) and similarly associated with the CTSQ score (r = -.64, p < .001). Age at time of surveys and presence of any disability were also independently associated with PedsQL and PedsQL-TM, respectively. When adjusted for Emotional Functioning, CTSQ remained associated with PedsQL subscores (r = -.65, p < .001). Trauma symptoms are a major modifiable risk factor for lower self-perceived QOL and represent a potentially important target for post-transplant rehabilitation. Additional research is needed to understand the root contributors to PTSD and potential treatments in this population.

The role of extracorporeal membrane oxygenation in pediatric abdominal transplant patients: A qualitative systematic review of literature. Pediatr Transplant 2021; 25:e13939. [PMID: 33314532 DOI: 10.1111/petr.13939] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/18/2020] [Revised: 11/02/2020] [Accepted: 11/13/2020] [Indexed: 11/28/2022]
Abstract
BACKGROUND Advances in ECMO have made it a useful adjunct in critically ill pediatric patients; however, a dearth of evidence exists regarding risks and benefits in pediatric abdominal transplantation. The purpose of this study was to perform a qualitative systematic review of outcomes in pediatric patients undergoing ECMO support pre- or post-abdominal organ transplantation. METHODS This was a systematic review conducted from Jan 1, 1989, to April 24, 2020, via PubMed, Embase, Scopus, Web of Science, the Cochrane Library, and ClinicalTrials.gov of all pediatric solid abdominal organ transplant recipients (pre- and post-transplant) and donors who underwent V-A or V-V ECMO cannulation. Death was the primary outcome, with graft function and complications as secondary outcomes. RESULTS Fourteen articles were identified that fit criteria, with 88% being case reports. Three patients were donors placed on ECMO, with no mortality among the 8 recipients of organs from these donors. Nineteen recipients were placed on ECMO. All were liver transplants. Most patients experienced at least one complication (84%), with bleeding as the most common cause (44%). Mortality was 26%. Causes of death included multiorgan system failure (n = 3), heart failure (n = 1), Systemic inflammatory response syndrome (n = 1), abdominal compartment syndrome (n = 3), bleeding (n = 1), septic shock from aspergillus (n = 1), and hepatic artery thrombosis (n = 2). CONCLUSIONS The data are poor on ECMO usage in pediatric abdominal transplantation. While complications were high, mortality did not appear to be related to ECMO usage and was relatively low given the severity of patient illness.

Abstract
OBJECTIVE Much of the extant literature on adherence barriers has focused on modifiable factors (e.g., knowledge, social support); however, less is known about how barriers may be associated with relatively stable constructs, such as personality traits. The current study examines associations between personality (i.e., agreeableness, conscientiousness, neuroticism) and adherence barriers in a group of adolescent and young adult (AYA) solid organ transplant recipients. Demonstrating associations between barriers and personality may help in understanding why barriers are stable over time. Additionally, different personality traits may relate to different types of barriers. METHODS The sample included 90 AYAs (Mage = 17.31; SD = 2.05; 58% male) who received a kidney (n = 36), liver (n = 29), or heart (n = 25) transplant at least 1 year prior to study enrollment. AYAs completed the Agreeableness, Conscientiousness, and Neuroticism scales from the NEO Five-Factor Inventory and the Adolescent Medication Barriers Scale (AMBS). RESULTS Lower levels of agreeableness and conscientiousness and higher levels of neuroticism were related to higher self-reported barrier scores (AMBS; r's = .31- .53, p's < .001). The relations differed by personality factor and barrier type. CONCLUSION Adherence barriers showed medium to large associations with personality traits that are known to be relatively stable. Our findings indicate that the temporal stability of barriers to adherence may be due in part to their association with relatively enduring personality characteristics.

Abstract
As survival post-liver transplantation (LTx) improves, it becomes increasingly important to understand how long-term health-related quality of life (HRQOL) is impacted. This was a longitudinal review examining HRQOL measured by Pediatric Liver Transplant Quality of Life (PeLTQL) in children between 8-17 years who underwent LTx (1.4 [0.8–3.3] years) at least one year prior to assessment. Demographic, medical, anthropometric, and HRQOL data (self-reported and parent proxy) were retrospectively collected over four years (2014–2017) at annual LTx clinic visits. The study included 35 patients (18M, 17F) and their parents/guardians. Parent-proxy and child PeLTQL scores (total, subdomain) showed good to excellent agreement (p > 0.05) and did not change over four years (p > 0.05). Younger age (<12 years) and Caucasian ancestry were associated with higher parental and self-reported perceptions of HRQOL, respectively (future health, coping and adjustment, total scores). Parent perceived lower HRQOL in social–emotional sub-domain (p = 0.03) and the child reported lower sub-domain scores related to coping and adjustment (p = 0.04) when the child was noted to have co-morbid conditions related to mental health and neurocognitive development (25.7%). While child–parent perceptions of HRQOL in a multi-ethnic population of pediatric LTx recipients remain unchanged 10 years post-LTx, adolescents of non-Caucasian ancestry remain a population at risk for lower HRQOL.

Abstract
OBJECTIVES Prediction of post-transplant health outcomes and identification of key factors remain important issues for pediatric transplant teams and researchers. Outcomes research has generally relied on general linear modeling or similar techniques offering limited predictive validity. Thus far, data-driven modeling and machine learning (ML) approaches have had limited application and success in pediatric transplant outcomes research. The purpose of the current study was to examine ML models predicting post-transplant hospitalization in a sample of pediatric kidney, liver, and heart transplant recipients from a large solid organ transplant program. MATERIALS AND METHODS Various logistic regression, naive Bayes, support vector machine, and deep learning (DL) methods were used to predict 1-, 3-, and 5-year post-transplant hospitalization using patient and administrative data from a large pediatric organ transplant center. RESULTS DL models generally outperformed traditional ML models across organtypes and prediction windows with area under the receiver operating characteristic curve values ranging from 0.750 to 0.851. Shapley additive explanations (SHAP) were used to increase the interpretability of DL model results. Various medical, patient, and social variables were identified as salient predictors across organ types. DISCUSSION Results demonstrate the utility of DL modeling for health outcome prediction with pediatric patients, and its use represents an important development in the prediction of post-transplant outcomes in pediatric transplantation compared to prior research. CONCLUSION Results point to DL models as potentially useful tools in decision-support systems assisting physicians and transplant teams in identifying patients at a greater risk for poor post-transplant outcomes.

Abstract
As the number of living pediatric solid organ transplant (SOT) recipients continues to grow, there is an increased likelihood that primary care providers (PCPs) will encounter pediatric SOT recipients in their practices. In addition, as end-stage organ failure is replaced with chronic medical conditions in transplant recipients, there is a need for a comprehensive approach to their management. PCPs can significantly enhance the care of immunosuppressed hosts by advising parents of safety considerations and avoiding adverse drug interactions. Together with subspecialty providers, PCPs are responsible for ensuring that appropriate vaccinations are given and can play an important role in the diagnosis of infections. Through early recognition of rejection and posttransplant complications, PCPs can minimize morbidity. Growth and development can be optimized through frequent assessments and timely referrals. Adherence to immunosuppressive regimens can be greatly improved through reinforcement at every encounter, particularly among adolescents. PCPs can also improve long-term outcomes by easing the transition of pediatric SOT recipients to adult providers. Although guidelines exist for the primary care management of adult SOT recipients, comprehensive guidance is lacking for pediatric providers. In this evidence-based overview, we outline the main issues affecting pediatric SOT recipients and provide guidance for PCPs regarding their management from the first encounter after the transplant to the main challenges that arise in childhood and adolescence. Overall, PCPs can and should use their expertise and serve as an additional layer of support in conjunction with the transplant center for families that are caring for a pediatric SOT recipient.

Abstract
BACKGROUND Obesity is a significant public health concern; however, the incidence post solid-organ transplantation is not well reported. METHODS This study determined the incidence and risk factors of obesity among pediatric solid-organ transplant recipients (heart, lung, liver, kidney, multiorgan) at The Hospital for Sick Children (2002-2011), excluding prevalent obesity. Follow-up occurred from transplantation until development of obesity, last follow-up, or end of study. Incidence of obesity was determined overall, by baseline body mass index, and organ group. Risk factors were assessed using Cox proportional-hazards regression. RESULTS Among 410 (55% male) children, median transplant age was 8.9 (interquartile range [IQR]: 1.0-14.5) years. Median follow-up time was 3.6 (IQR: 1.5-6.4) years. Incidence of obesity was 65.2 (95% confidence interval [CI]: 52.7-80.4) per 1000 person-years. Overweight recipients had a higher incidence, 190.4 (95% CI: 114.8-315.8) per 1000 person-years, than nonoverweight recipients, 56.1 (95% CI: 44.3-71.1). Cumulative incidence of obesity 5-years posttransplant was 24.1%. Kidney relative to heart recipients had the highest risk (3.13 adjusted hazard ratio [aHR]; 95% CI: 1.53-6.40) for obesity. Lung and liver recipients had similar rates to heart recipients. Those with higher baseline body mass index (z-score; 1.72 aHR; 95% CI: 1.39-2.14), overweight status (2.63 HR; 95% CI: 1.71-4.04), and younger transplant age (y; 1.18 aHR; 95% CI: 1.12-1.25) were at highest risk of obesity. Higher cumulative steroid dosage (per 10 mg/kg) was associated with increased risk of obesity after adjustment. CONCLUSIONS Among all transplanted children at The Hospital for Sick Children, 25% developed obesity within 5-years posttransplant. Kidney recipients, younger children, those overweight at transplant, and those with higher cumulative steroid use (per 10 mg/kg) were at greatest risk. Early screening and intervention for obesity are important preventative strategies.

Abstract
PA has been shown to have benefits in SOT patients. Studies assessing physical activity levels and its correlates in a pediatric solid-organ transplant population are limited. The aim of this study was to assess PA levels and identify baseline and contemporaneous factors that contribute to PA in a pediatric SOT population. A retrospective cross-sectional review was performed on 58 pediatric transplant patients (16 heart, 29 kidney, and 13 liver transplant). PA was measured by PAQ-C or PAQ-A. Demographics, baseline, and contemporaneous factors were collected. There were no significant differences in baseline and contemporaneous characteristics between heart, kidney, and liver transplant recipients. SOT recipients were 15.2 [12.3-17.3] years old at time of completing the PAQ. Median PAQ score was 2.2 [1.7-2.9]. There were no significant differences in PAQ scores between organ transplant type or between genders. Lower PAQ score was associated with sensory disability (9 vs 49 without disability; P = <.01) and age at time of completing the PAQ (r = -.50, P = <.01). These results suggest that older age at time of completing the PAQ and presence of sensory disability may influence PA levels in the pediatric SOT population.

Abstract
INTRODUCTION Mobile health (mHealth) is the use of mobile communication devices such as smartphones, wireless patient monitoring devices and tablet computers to deliver health services. Paediatric surgery patient care could potentially benefit from these technologies. This systematic review summarises the current literature on the use of mHealth for postoperative care after children's surgery. METHODS Seven databases were searched by a senior medical librarian. Studies were included if they reported the use of mHealth systems for postoperative care for children <18 years old. Data extraction and risk of bias assessment were performed in duplicate. RESULTS A total of 18 studies were included after screening. mHealth use was varied and included appointment or medication reminders, postoperative monitoring and postoperative instruction delivery. mHealth systems included texting systems and mobile applications, and were implemented for a wide range of surgical conditions and countries. DISCUSSION Studies showed that mHealth systems can increase the postoperative follow-up appointment attendance rate (p < 0.001), decrease the rate of postoperative complications and returns to the emergency department and reliably monitor postoperative pain. mHealth systems were generally appreciated by patients. Most non-randomised and randomised studies had many methodological problems, including lack of appropriate control groups, lack of blinding and a tendency to devote more time to the care of the intervention group. mHealth systems have the potential to improve postoperative care, but the lack of high-quality research evaluating their impact calls for further studies exploring evidence-based mHealth implementation.

Abstract
The small intestine (SI) is difficult to regenerate or reconstruct due to its complex structure and functions. Recent developments in stem cell research, advanced engineering technologies, and regenerative medicine strategies bring new hope of solving clinical problems of the SI. This review will first summarize the structure, function, development, cell types, and matrix components of the SI. Then, the major cell sources for SI regeneration are introduced, and state-of-the-art biofabrication technologies for generating engineered SI tissues or models are overviewed. Furthermore, in vitro models and in vivo transplantation, based on intestinal organoids and tissue engineering, are highlighted. Finally, current challenges and future perspectives are discussed to help direct future applications for SI repair and regeneration.

Abstract
Listing the world's first pediatric bilateral hand transplant patient for a donor posed many challenges including matching the appropriate donor age, bone size, skin tone, and growth potential in an already limited donor population. This study describes the prevalence and distribution of potential pediatric VCA donors in the United States. We assessed the UNOS database from 2008 to 2015 to identify the prevalence of potential pediatric VCA donors. Standard VCA inclusion and exclusion criteria were applied to the dataset for all pediatric solid organ donors. Frequency analyses were performed of characteristics important for VCA matching. The dataset began with 57 300 brain-dead donors and after applying the inclusion and exclusion criteria including age <18, decreased to 4663 (8.1%). The number of pediatric potential VCA donors per UNOS region ranged from 11 to 112/year. The majority of pediatric potential VCA donors were blood type O Whites, with the least common profile being blood type AB of "other" ethnicity. The present study confirmed that pediatric VCA donors are rare and may require longer travel times for procurement and listing at multiple centers in order to find a suitable donor. This will be a limiting factor for the expansion of pediatric VCA.

Abstract
Pediatric transplant recipients experience barriers to social functioning, including participation in school and work, but our understanding of barriers to these activities is limited by insufficient data collection and standardization. Existing studies rely on cross-sectional surveys of transplant survivors that are subject to survivorship and nonresponse bias, or analyses of large registry data that lack detail on educational progress and work participation. We report our experience using the electronic medical record to retrospectively review work and educational attainment in this population, and identify specific barriers that were encountered and how they were addressed by the patient and care team. We reviewed current literature on post-transplant survey participation and compared questionnaires to our current documentation practice for tracking education and employment progress in the transplant recipient population. Based on this review, we discuss the possibility, barriers, and implications of conducting a standardized assessment to track social participation outcomes of transplantation.

Abstract
BACKGROUND Hyperbilirubinemia that occurs in pediatric liver diseases such as biliary atresia can result in the development of not only jaundice in the brain, eyes, and skin, but also tooth abnormalities including green pigmentation and dentin hypoplasia in the developing teeth. However, hyperbilirubinemia-induced tooth impairments remain after liver transplantation. No effective dental management to prevent hyperbilirubinemia-induced tooth impairments has been established. METHODS In this study, we focused on pamidronate, which is used to treat pediatric osteopenia, and investigated its effects on hyperbilirubinemia-induced tooth impairments. We cultured stem cells from human exfoliated deciduous teeth (SHED) under high and low concentrations of unconjugated bilirubin in the presence or absence of pamidronate. We then analyzed the effects of pamidronate on the cell death, associated signal pathways, and dentinogenic function in SHED. RESULTS We demonstrated that a high concentration of unconjugated bilirubin induced cell death in SHED via the mitochondrial pathway, and this was associated with the suppression of AKT and extracellular signal-related kinase 1 and 2 (ERK1/2) signal pathways and activation of the nuclear factor kappa B (NF-κB) signal pathway. The high concentration of unconjugated bilirubin impaired the in vitro and in vivo dentinogenic capacity of SHED, but not the low concentration. We then demonstrated that pamidronate decreased the bilirubin-induced cell death in SHED via the altered AKT, ERK1/2, and NF-κB signal pathways and recovered the bilirubin-impaired dentinogenic function of SHED. CONCLUSIONS Our findings suggest that pamidronate may prevent tooth abnormalities in pediatric patients with hyperbilirubinemia.

Abstract
OBJECTIVE Paediatric solid organ transplantation is an increasingly successful treatment. Improved survival is paralleled by increased secondary complications of immunosuppression, including post-transplant lymphoproliferative disease (PTLD). PTLD frequently presents in Waldeyer's lymphatic ring. Adenotonsillar hypertrophy (ATH) is common in children, however in children after transplant, ATH may indicate PTLD. We review the literature on ATH and the role of adenotonsillectomy in children after transplantation. METHODS A comprehensive literature search was performed on the 26 th September 2017 of Ovid Medline (1996-September 2017), Embase (1996-2017) and EBM reviews (Cochrane database of systematic reviews 2005-September 20 th 2017). Results were limited to English language publications within the last 20 years. Abstracts were screened for relevance to PTLD and ATH in the paediatric solid organ transplantation population. Screening of the bibliographies identified further articles. RESULTS 85 unique articles were screened to yield 18 relevant publications. 10 were retrospective studies and 8 were prospective studies. CONCLUSION In children, we report a PTLD incidence of up to 15%, with up to 63% of cases presenting in the head and neck. Histological examination of adenotonsillectomy specimens found PTLD in a mean 5.7% (range 0-39%). We found a lack of prospective studies into this topic and further high quality research is needed. Clinical assessment of ATH in children after transplantation and when to perform a diagnostic adenotonsillectomy remains challenging. Children with ATH warrant prompt further investigation and support from colleagues in transplantation and oncology is required. .

Abstract
The present study is to evaluate the feasibility and efficacy of microwave ablation (MWA) combined with transcatheter arterial chemoembolization (TACE) in the treatment for unresectable hepatoblastoma in infants and children. A total of 17 patients with PRETEXT stage III and IV hepatoblastoma that was unresectable by conventional resection were included in the present study. The patients were treated with TACE, MWA, and chemotherapy. All cases were diagnosed by computed tomography (CT) and liver tumor biopsy before TACE procedure. All patients received 2 courses of TACE and 1 to 2 times of MWA. Finally, several cycles of chemotherapy were arranged. Among the 17 patients, 14 were alive and had normal alpha-fetoprotein (AFP) levels. The other 3 patients died from tumor progression. The follow-up periods ranged from 10 to 68 months. Complete ablation was achieved in the 14 patients (14/17, 82.35%). Most patients were well tolerated during the whole course except for 1 patient with pneumonedema after TACE and another 1 with biloma after MWA. No marked chemotherapeutic agent-induced toxicity occurred. After chemotherapy or TACE, transient blood indicators and symptoms were observed as follows: myelosuppression, abnormal liver function, gross hematuria, fever, and abdominal pain. Transient symptoms after MWA were fever, abdominal pain, and massive gross hematuria. The present study demonstrates that MWA combined with TACE is a safe and effective method for treating unresectable hepatoblastoma in infants and children with controllable side effects.

Abstract
Immunosuppression following solid organ transplantation (SOT) has a deleterious effect on cellular immunity leading to frequent and prolonged viral infections. To better understand the relationship between posttransplant immunosuppression and circulating virus-specific T cells, we prospectively monitored the frequency and function of T cells directed to a range of latent (CMV, EBV, HHV6, BK) and lytic (AdV) viruses in 16 children undergoing liver transplantation for up to 1 year posttransplant. Following transplant, there was an immediate decline in circulating virus-specific T cells, which recovered posttransplant, coincident with the introduction and subsequent routine tapering of immunosuppression. Furthermore, 12 of 14 infections/reactivations that occurred posttransplant were successfully controlled with immunosuppression reduction (and/or antiviral use) and in all cases we detected a temporal increase in the circulating frequency of virus-specific T cells directed against the infecting virus, which was absent in 2 cases where infections remained uncontrolled by the end of follow-up. Our study illustrates the dynamic changes in virus-specific T cells that occur in children following liver transplantation, driven both by active viral replication and modulation of immunosuppression.

Abstract
This study examined the demographic, medical, and psychiatric characteristics of transplant patients across organ groups seen by transplant psychology/psychiatry clinicians at a pediatric institution between 2008 and 2014. Chart reviews were conducted to better understand the behavioral health care provided to SOT patients and the role of transplant-dedicated psychology and psychiatry clinicians. Transplant psychology/psychiatry was consulted a total of 1060 times on 399 unique SOT patients over a 6-year period. There were no significant differences in the distribution of age, sex, or ethnicity across organ groups. Common reasons for a consultation included pretransplant evaluation, anxiety, depression, agitation, and general coping. Rates varied by organ groups. Twenty percent of consults also received a psychopharmacological evaluation, with differences in rates between organ groups. Roughly one-third of patients required high frequency of transplant psychology/psychiatry involvement. Lung and heart patients had the highest utilization. Psychiatric diagnosis rates were identified, with adjustment (41.0%) and anxiety disorders (30.1%) being the most common. Pediatric psychology and psychiatry clinicians offer developmentally informed biopsychosocial approaches to treatment for SOT patients. Clarifying the prevalence and nature of behavioral health care provided by organ group can help pediatric providers better understand appropriate psychosocial interventions and resources utilized by this patient population and ultimately guide centers toward a more unified approach to care.

Abstract
This prospective study investigated growth and skeletal development for 3 years after kidney transplantation in pediatric patients, 3.4-15.0 years of age. Growth, BMD, bone resorption markers (CTX and TRACP5b), bone formation markers (PINP, ALP, and osteocalcin), PTH, and vitamin D were assessed at start, 3, 12, and 36 months after transplantation. Median GFR was 63 (range 37-96) mL/min/1.73 m2 after 3 years. The median height SDS increased from -1.7 to -1.1, and median BMI SDS increased from -0.1 to 0.6 over 3 years, which shows that transplantation had a favorable outcome on growth. Fat mass increased after transplantation at all time points, whereas lean mass increased after 1 year and 3 years. Total BMC increased at all time points. No changes were observed for total BMD. Bone resorption markers decreased initially after 3 months and remained stable throughout the study, whereas the bone formation markers decreased initially, but successively increased over the study period. In conclusion, this study demonstrates that height SDS and BMI SDS increased, along with the increased formation markers that reveal a positive bone acquisition after kidney transplantation, which was reflected by the significant increase in total body BMC.

Abstract
OBJECTIVE Hyperbilirubinemia in patients with biliary atresia causes deciduous tooth injuries such as green pigmentation and dentin hypoplasia. In patients with biliary atresia who received liver transplantation, tooth structure appears to be recovered radiographically. Nevertheless, little is known about cellular mechanisms underlying bilirubin-induced damage and suppression of deciduous tooth formation. In this study, we examined the effects of bilirubin in stem cells from human exfoliated deciduous teeth (SHED) in vitro. MATERIALS AND METHODS SHED were cultured under exposure to excess of bilirubin and then interruption of bilirubin stimulation. RESULTS Bilirubin induced cell death and inhibited the odontogenic capacity of SHED by suppressing AKT and extracellular signal-regulated kinase 1 and 2 (ERK1/2) pathways and enhancing nuclear factor kappa B p65 (NF-κB p65) pathway. The interruption of bilirubin stimulation reduced cell death and recovered the inhibited odontogenic capacity of bilirubin-damaged SHED. The bilirubin interruption also normalized the impaired AKT, ERK1/2, and NF-κB p65 signaling pathways. CONCLUSION These findings suggest that tooth hypodontia in patients with hyperbilirubinemia might be due to bilirubin-induced cell death and dentinogenic dysfunction of odontogenic stem cells via AKT, ERK1/2, and NF-κB pathways and also suggested that bilirubin-induced impairments in odontogenic stem cells were reversible when bilirubin stimulation is interrupted.

Abstract
BACKGROUND Health-related quality of life (HRQOL) is an important outcome in solid organ transplantation. This study evaluated and explored the factors of generic and transplant-specific HRQOL in Japanese pediatric and adolescent patients with biliary atresia (BA) after living donor liver transplant (LDLT). METHODS A cross-sectional survey using anonymous questionnaires was completed between April and July 2015. Patient medical records were accessed. The Japanese version of Pediatric Quality of Life InventoryTM Generic Core Scales and Transplant Modules (child self-report and parent proxy-report) was administered. RESULTS Participants consisted of 75 patients (mean age at survey, 9.6 years) and 74 parents. Japanese patients reported higher generic and transplant-specific HRQOL (total score) than that reported by US patients with BA after LT (US I; age at survey, 7.2 years) and by US patients after solid organ transplant (US II; age at survey, 11.3 years; LT, 53.8%; effect size, 0.55-0.96). Japanese parents, however, rated their children's generic HRQOL (total score) similar to that rated by the US I and II parents (0.13 and 0.30, respectively) and reported lower transplant-specific HRQOL (total score) than that reported by US II (0.26). Although the number of types of prescribed drugs was a common factor in HRQOL, most demographic and medical factors (e.g. child's age at survey and consultation frequency) varied with reporter (i.e. patients and parents). CONCLUSIONS The levels and factors of generic and transplant-specific HRQOL of Japanese pediatric and adolescent patients with BA after LDLT varied with reporter (i.e. patients or parents).

Abstract
In recent decades, there have been tremendous improvements in burn care that have allowed patients to survive severe burn injuries that were once fatal. However, a major limitation of burn care currently is the development of hypertrophic scars in approximately 70% of patients. This significantly decreases the quality of life for patients due to the physical and psychosocial symptoms associated with scarring. Current approaches to manage scarring include surgical techniques and non-surgical methods such as laser therapy, steroid injections, and compression therapy. These treatments are limited in their effectiveness and regularly fail to manage symptoms. As a result, the development of novel treatments that aim to improve outcomes and quality of life is imperative. Drug delivery that targets the molecular cascades of wound healing to attenuate or prevent hypertrophic scarring is a promising approach that has therapeutic potential. In this review, we discuss current treatments for scar management after burn injury, and how drug delivery targeting molecular signaling can lead to new therapeutic strategies.

Abstract
OBJECTIVES Cutaneous lesions are often the first marker of invasive mold infection, which can cause substantial morbidity in immunocompromised children. The purpose of this study was to describe the evaluation and outcomes of immunocompromised children who presented with findings requiring skin biopsy because of concern about invasive infection. In children who were biopsied, we sought to determine the factors predictive of invasive mold infection. METHODS A retrospective review was conducted at the Children's Hospital of Philadelphia. Patients included in the study were immunocompromised individuals younger than 26 years old who underwent skin biopsy by the inpatient dermatology consultation team between January 1, 2003, and March 15, 2015, because of development of new cutaneous lesions that were suspected of being invasive infection. RESULTS One hundred five encounters met the inclusion criteria. Fifty (47.6%) biopsied individuals had an infectious pathogen identified on histopathology or culture. Mold was the most common (36%) pathogen, followed by bacteria (32%) and yeast (26%). The presence of a single lesion (P = .001) and prior occlusion at the site of the lesion (P < .001) were associated with mold on biopsy. The combination of a single lesion, history of occlusion, and tissue necrosis on examination was highly predictive for invasive mold infection (86.3% [95% confidence interval 55.1-97.0%]). Of the 18 individuals with confirmed invasive mold infection, 13 (72%) underwent surgical resection, of whom 12 (92%) survived the 30-day follow-up period. CONCLUSION Skin biopsy enabled the detection of a pathogen that informed directed therapeutic interventions in nearly half of participants. Institutions caring for immunocompromised children should ensure adequate staffing of clinical personnel approved to perform skin biopsies.

Abstract
PURPOSE Compared to other solid organs, survival after lung transplantation (LTx) is still poor. Discussions on survival benefits following LTx in children, however, have largely concentrated on medical outcome data. Little research describes quality of life (QoL) of pediatric LTx recipients, which is partly due to the small number of pediatric LTxs performed. Only two centers worldwide performed >10 pediatric LTxs in 2013, making data on QoL in this population difficult to obtain. The primary objective was to examine the impact of LTx on QoL of pediatric recipients. METHODS LTx recipients aged 8-17 years and their parents were recruited from a Canadian pediatric transplant centre. Participants completed the PedsQL 4.0 Generic Core Scales, a validated health-related QoL patient-reported outcome measure for children and adolescents, pre-transplant and two times post-transplant. Pre-LTx QoL scores were compared with initial assessment scores post-LTx and changes in QoL over time were described. Correlations between self- and proxy-reports were also discussed. RESULTS Ten pediatric LTx recipients (six male, mean age = 13.3 years) and their parents were enrolled. Assessments were completed pre-LTx (mean months = 4.8) and two times post-LTx (mean months 8.7 and 24.6, respectively). Pre- and post-transplant total scores differed significantly for both self- and proxy-report, which remained consistent at a second assessment post-transplant (P = 0.018 and 0.028, respectively). CONCLUSIONS Findings highlight the importance of QoL outcomes when exploring LTx as a treatment option. Future research should explore long-term QoL outcomes post-LTx and examine standardized integration of patient-reported outcomes into clinical practice.

Abstract
Adherence is proving to be the Achilles heel of pediatric transplantation. Through a careful literature review on adherence in pediatric solid-organ transplantation from 2007 to 2017, this chapter reports on the incidence, measuring tools, and consequences of poor adherence. We detail adherence determinants and interventions proposed to foster it. While adherence is a major problem in the adolescent age, it clearly is not limited to this age group. Importantly, it is not one to start tackling at that time or when it becomes apparent. Rather, fostering adherence should be built throughout the continuum of the transplant journey, starting in the pretransplantation phase. Adherence is clearly a fluid state, necessitating frequent reassessments and enforcement. Adherence in addition shares similar determinants with quality of life. The severe consequences in the case of poor adherence mandate that the transplant community prioritize it as the next frontier in transplantation. Good adherence is what will pave the road to tolerance, cost-efficient transplantation, and optimized long-term outcomes.

Abstract
The post-transplant lymphoproliferative disorders (PTLD) are a diverse group of potentially life-threatening conditions affecting organ transplant recipients. PTLD arises in the setting of an attenuated host immunologic system that is manipulated to allow a foreign graft but then fails to provide adequate immune surveillance of transformed malignant or premalignant lymphocytes. The diversity of biological behavior and clinical presentation makes for a challenging clinical situation for those involved in the care of children with PTLD occurring after solid-organ transplantation. This review details a large transplant center's multidisciplinary approach to monitoring for PTLD and systematic approach to intervention, which has been essential for early recognition and successful treatment.

Abstract
BACKGROUND A number of corticosteroid minimization and avoidance protocols for post-solid organ transplant have been developed. The study objective was to examine the effect of corticosteroid withdrawal/avoidance on growth and safety parameters in pediatric solid organ transplant recipients. METHODS A systematic review using Medline and Embase was performed. All randomized controlled trials (RCT) and observational studies comparing corticosteroid withdrawal/avoidance to controls receiving corticosteroids in pediatric transplant recipients which reported growth as change in height or final height were included. Two reviewers independently abstracted study data and assessed quality. RESULTS The search yielded 930 records, 14 separate studies involving 1146 patients. Renal RCTs (n = 5) showed that corticosteroid withdrawal/avoidance was associated with a significant increase in growth (mean difference in height standard deviation score [SDS], 0.18; 95% confidence interval [95% CI], 0.07-0.29; P = 0.001) compared with those remaining on steroids. In liver RCTs (n = 2), mean difference in height SDS was -0.20 (95% CI, -1.08 to 0.68; P = 0.66). Results for renal observational studies (n = 5) was 0.34 (95% CI, 0.03-0.65; P = 0.03). The most pronounced effect was seen in prepubertal children with SDS of 0.28 (95% CI, 0.14-0.41; P < 0.0001). In pubertal participants this was not observed (SDS, 0.06; 95% CI, -0.04 to 0.15; P = 0.24). Corticosteroid withdrawal/avoidance was not associated with acute rejection (odds ratio [OR], 0.87; P = 0.63), graft failure (OR, 0.45; P = 0.08), or death (OR, 0.34; P = 0.16) in renal trials. CONCLUSIONS Corticosteroid withdrawal/avoidance in pediatric renal transplantation is associated with a significant improvement in height. Prepubertal patients appeared to have the greatest benefit. Importantly, the improvement in growth was not accompanied by increased rejection or worsening patient/allograft survival in the short term.

Abstract
BACKGROUND Recipient adolescent age for non-lung solid-organ transplantation is associated with higher rates of rejection, graft loss and mortality. Although there have been no studies specifically examining adolescent outcomes after lung transplantation (LTx), limited data from the International Society of Heart and Lung Transplantation (ISHLT) Registry suggest that a similar association may exist. Recently, adolescence has been defined as 10 to 24 years of age, taking into account the biologic and sociologic transitions that occur during this age interval. METHODS The ISHLT Registry was used to examine the survival outcomes of LTx recipients 10 to 24 years of age between 2005 and 2013. Given the developmental changes that occur in adolescence, survival outcomes for the tertiles of adolescence (10 to 14, 15 to 19 and 20 to 24 years old) were also examined. RESULTS Adolescents made up 9% (n = 2,319) of the 24,730 LTxs undertaken during the study period. Kaplan-Meier survival estimates at 3 years showed lower adolescent survival (65%) when compared with younger children (73%, p = 0.006) and adults 25 to 34 (75%, p < 0.00001) and 35 to 49 (71%, p < 0.00001) years of age, without a significant survival difference compared with those 50 to 65 years old. Critically, 15- to 19-year-old recipients had the poorest outcomes, with reduced 1-year survival (82%) compared with those 10 to 14 years old (88%, p = 0.02), and reduced 3-year survival (59%) compared with those 10 to 14 (73%, p < 0.00001) and 20 to 24 (66%, p < 0.0001) years old. CONCLUSIONS Adolescent LTx recipients have poorer overall survival when compared with younger children and adults, with those 15 to 19 years old having the highest risk of death. This survival disparity among age groups likely reflects the difficult period of adolescence and its biologic and social transitions, which may influence both immunologic function and adherence.

Abstract
Pediatric liver transplantation has experienced improved outcomes over the last 50 years. This can be attributed in part to establishing optimal use of immunosuppressive agents to achieve a balance between minimizing the risks of allograft rejection and infection. The management of immunosuppression in children is generally more complex and can be challenging when compared with the use of these agents in adult liver transplant patients. Physiologic differences in children alter the pharmacokinetics of immunosuppressive agents, which affects absorption, distribution, metabolism, and drug excretion. Children also have a longer expected period of exposure to immunosuppression, which can impact growth, risk of infection (bacterial, viral, and fungal), carcinogenesis, and likelihood of nonadherence. This review discusses immunosuppressive options for pediatric liver transplant recipients and the unique issues that must be addressed when managing this population. Further advances in the field of tolerance and accommodation are needed to relieve the acute and cumulative burden of chronic immunosuppression in children.
