Pediatr Transplant. 2023 Dec;27(8):e14577 doi: 10.1111/petr.14577.
BACKGROUND:
A significant number of pediatric heart transplant recipients and their families experience post-traumatic stress symptoms following transplantation, which can impact recipient behavioral and medical health outcomes. Preventive behavioral health interventions may improve outcomes, especially if interventions can be delivered at a distance to decrease barriers to mental health care. This pilot study examined the acceptability and accessibility of an evidence-informed resilience training program delivered using a video telehealth platform. A secondary aim was to assess the preliminary efficacy of the intervention on recipient behavioral health outcomes, perceived barriers to recipient medication adherence, parent behavioral health outcomes, and family functioning. METHODS:Seventeen heart transplant recipients (8-18 years old) and their families were recruited and randomly assigned to a treatment as usual (n = 8) or an intervention group (n = 9). Baseline assessment data collected included demographic information and validated behavioral health measures. Follow-up assessments included the validated measures and acceptability and satisfaction ratings. RESULTS:The study demonstrated that the program has high acceptability by recipients and parents, and a positive impact on recipients and parents, including significant reductions in youth behavioral difficulties as well as parent depression and post-traumatic stress symptoms. CONCLUSIONS:Results of this study are promising and call for further evaluation of hybrid delivery models for behavioral health screening and prevention interventions for pediatric heart transplant recipients and their families. |

BACKGROUND:
Currently there are no immunosuppression regimens FDA-approved to prevent rejection in pediatric heart transplantation (HT). In recent years, everolimus (EVL) has emerged as a potential alternative to standard tacrolimus (TAC) as the primary immunosuppressant to prevent rejection that may also reduce the risk of cardiac allograft vasculopathy (CAV), chronic kidney disease (CKD) and cytomegalovirus (CMV) infection. However, the 2 regimens have never been compared head-to-head in a randomized trial. The study design and rationale are reviewed in light of the challenges inherent in rare disease research. METHODS:The TEAMMATE trial (IND 127980) is the first multicenter randomized clinical trial (RCT) in pediatric HT. The primary purpose is to evaluate the safety and efficacy of EVL and low-dose TAC (LD-TAC) compared to standard-dose TAC and mycophenolate mofetil (MMF). Children aged <21 years at HT were randomized (1:1 ratio) at 6 months post-HT to either regimen, and followed for 30 months. Children with recurrent rejection, multi-organ transplant recipients, and those with an estimated glomerular filtration rate (eGFR) <30 mL/min/1.73m2 were excluded. The primary efficacy hypothesis is that, compared to TAC/MMF, EVL/LD-TAC is more effective in preventing 3 MATEs: acute cellular rejection (ACR), CKD and CAV. The primary safety hypothesis is that EVL/LD-TAC does not have a higher cumulative burden of 6 MATEs (antibody mediated rejection [AMR], infection, and post-transplant lymphoproliferative disorder [PTLD] in addition to the 3 above). The primary endpoint is the MATE score, a composite, ordinal surrogate endpoint reflecting the frequency and severity of MATEs that is validated against graft loss. The study had a target sample size of 210 patients across 25 sites and is powered to demonstrate superior efficacy of EVL/LD-TAC. Trial enrollment is complete and participant follow-up will be completed in 2023. CONCLUSION:The TEAMMATE trial is the first multicenter RCT in pediatric HT. It is anticipated that the study will provide important information about the safety and efficacy of everolimus vs tacrolimus-based regimens and will provide valuable lessons into the design and conduct of future trials in pediatric HT. |

Paediatric heart transplant recipients (HTRs) have reduced exercise capacity, physical activity (PA), health-related quality of life (HRQoL), and self-efficacy towards PA. Exercise interventions have demonstrated improvements in exercise capacity and functional status in adult HTRs, with a specific emerging interest in the role of high-intensity interval training (HIIT). Studies of exercise interventions in paediatric HTRs have been limited and nonrandomized to date. HIIT has not yet been evaluated in paediatric HTRs. We thus seek to evaluate the safety and feasibility of a randomized crossover trial of a 12-week, home-based, video game-linked HIIT intervention using a cycle ergometer with telemedicine and remote physiological monitoring capabilities (MedBIKE) in paediatric HTRs. The secondary objective is to evaluate the impact of the intervention on (1) exercise capacity, (2) PA, (3) HRQoL and self-efficacy towards PA, and (4) sustained changes in secondary outcomes at 6 and 12 months after intervention. After a baseline assessment of the secondary outcomes, participants will be randomized to receive the MedBIKE intervention (12 weeks, 36 sessions) or usual care. After the intervention and a repeated assessment, all participants will cross over. Follow-up assessments will be administered at 6 and 12 months after the MedBIKE intervention. We anticipate that the MedBIKE intervention will be feasible and safely yield sustained improvements in exercise capacity, PA, HRQoL, and self-efficacy towards PA in paediatric HTRs. This study will serve as the foundation for a larger, multicentre randomized crossover trial and will help inform exercise rehabilitation programmes for paediatric HTRs. |

OBJECTIVES:
Our study was conducted to determine the effects of intraoperative antithymocyte globulin administration on donor hearts procured after cardiocirculatory death. We evaluated the impact of antithymocyte globulin on graft function and related parameters during isothermic blood cardioplegia. MATERIALS AND METHODS:In this prospective and randomized single center study, 30 patients with orthotropic heart transplant were divided into 2 groups: group 1 included 15 patients who received retrograde antithymocyte globulin infusion via coronary sinus intraoperatively and immediately after organ procurement and group 2 included 15 patients who received traditional antithymocyte globulin infusion after implantation. RESULTS:Study patients had a mean age of 33.8 years (range, 15-56 y). All patients had panel reactive antibody less than 10% except for 3 patients. The cluster of differentiation 3-positive cell count decrease was more than 20%. The inotropic therapy dose required and the myocardial pressure (stiffness) were less for group 1 patients. These patients had less acute rejection episodes than group 2 (0% vs 13.3%; P < .05). CONCLUSIONS:Favorable clinical outcomes were observed in terms of less acute rejection episodes and better graft function at least during the early posttransplant period. Intraoperative antithymocyte globulin treatment may have a preventive effect for acute cellular rejection in heart transplant patients. |

BACKGROUND:
Around 1800 pediatric transplantations were performed in 2021, which is approximately 5% of the annual rate of solid organ transplantations carried out in the United States. Effective family self-management in the transition from hospital to home-based recovery promotes successful outcomes of transplantation. The use of mHealth to deliver self-management interventions is a strategy that can be used to support family self-management for transplantation recipients and their families. OBJECTIVE:The study aims to evaluate the acceptability of an mHealth intervention (myFAMI) that combined use of a smartphone app with triggered nurse communication with family members of pediatric transplantation recipients. METHODS:This is a secondary analysis of qualitative data from family members who received the myFAMI intervention within a larger randomized controlled trial. Eligible participants used the app in the 30-day time frame after discharge and participated in a 30-day postdischarge telephone interview. Content analysis was used to generate themes. RESULTS:A total of 4 key themes were identified: (1) general acceptance, (2) positive interactions, (3) home management after hospital discharge, and (4) opportunities for improvement. CONCLUSIONS:Acceptability of the intervention was high. Family members rated the smartphone application as easy to use. myFAMI allowed the opportunity for families to feel connected to and engage with the medical team while in their home environment. Family members valued and appreciated ongoing support and education specifically in this first 30 days after their child's hospital discharge and many felt it contributed positively to the management of their child's medical needs at home. Family members provided recommendations for future refinement of the app and some suggested that a longer follow-up period would be beneficial. The development and refinement of mHealth care delivery strategies hold potential for improving outcomes for solid organ transplantation patients and their families and as a model to consider in other chronic illness populations.

OBJECTIVE:
Distraction can reduce pain and distress associated with painful procedures but has never been studied in children with solid organ transplants. We aimed to determine whether there is a difference in pain and distress associated with venipuncture in pediatric posttransplant patients who receive distraction compared with those who do not. METHODS:Randomized controlled trial of children aged 4 to 17 years with solid organ transplants undergoing venipuncture in the outpatient setting. Patients were randomized to receive distraction or no distraction. The primary outcome was the Faces Pain Scale-Revised. Secondary outcomes were the Observational Scale of Behavioral Distress-Revised; Faces, Leg, Activity, Cry, Consolability; and Children's Hospital of Eastern Ontario Pain Scale. Exploratory outcomes included the number of venipuncture attempts, time to successful venipuncture, and satisfaction of phlebotomists and parents. RESULTS:Median age of the 40 children enrolled was 11.5 years. Type of transplants included the heart (67.5%), kidney (22.5%), liver (7.5%), and more than 1 organ (2.5%). There was no difference between the Faces Pain Scale-Revised scores in distraction and no distraction groups (1.4; 95% confidence interval, 0.9-1.9; and 1.3, 95% confidence interval, 0.5-2.1, respectively). There was also no difference in the Observational Scale of Behavioral Distress-Revised; Faces, Leg, Activity, Cry, Consolability; and Children's Hospital of Eastern Ontario Pain Scale scores, number of venipuncture attempts, or time to successful venipuncture. Phlebotomists were more satisfied with the venipuncture when distraction was implemented. CONCLUSIONS:In children with solid organ transplants, there was no difference in pain and distress associated with venipuncture between those who did and did not receive distraction. There was also no difference in other procedure-related outcomes except for greater phlebotomist satisfaction when distraction was implemented. |

Children with CHD, especially heart-transplanted patients, are predisposed to have caries lesions, gingivitis and other oral findings like gingival hyperplasia. The aim of the study was the implementation of a specific oral hygiene program in these patients and its effect on the improvement of oral health, especially gingival overgrowth. For this, we used a newly developed systematic GHI to evaluate and describe this gingival alteration. Thirty-three children, aged 6 to 15 years with cardiac transplants (9 girls, 24 boys), were examined and introduced into a specific oral hygiene program. Each child showed evidence of gingival hyperplasia. They were randomly divided into three groups with the following oral care measurements: Group ZZ tooth brushing, Group ZZS tooth brushing and mouth rinsing, Group ZZSS tooth brushing, mouth rinsing and the use of an additional single and sulcus toothbrush. A significant decline of all oral health parameters could be proven in all groups. Gingival hyperplasia (GHI) improved as well as plaque accumulation (QHI). The children who used in addition to toothbrushing rinsing solutions and/or additional miniature toothbrushes showed better parameters of the gingival hygiene indexes from the baseline examination until the end of the study. The results show that any infant with cardiac transplant has to be introduced into an individualized oral hygiene program underlining the need of comprehensive dental care in cooperation with pediatric cardiology. |

BACKGROUND:
As organ donation registration rates remain low, especially among lower-educated people, it is important to support this group in making their registration decision. To prepare lower-educated students in the Netherlands for making a well-informed decision, an interactive educational program was developed. We aim to understand both the (quality of) implementation as well as to contextualize the effects of this program in a lower-educated school setting. METHODS:The process evaluation was part of a Cluster Randomized Controlled Trial, in which 11 schools for Intermediate Vocational Education throughout the Netherlands participated. Teachers who taught a course on Citizenship delivered three intervention elements (i.e. video fragments and discussion, quizzes with tailored feedback and an exercise filling out a registration form) to their students. Implementation was assessed by interviews with teachers, questionnaires from students, logbooks from teachers and user data from Google Analytics. RESULTS:The program was well received and implemented, but on-the-spot adaptations were made by teachers to fit their students better. Within the lower-educated target group, differences between students are high in terms of active participation, reading abilities, knowledge and attention span. The program fit well within their regular teaching activities, but the topic of organ donation is not always prioritized by teachers. CONCLUSIONS:We see opportunities to disseminate the program on a larger scale and reach a group that has been neglected in organ donation education before. Within the program, there are possibilities to increase the effectiveness of the program, such as alternative delivery methods for the elements with a lot of text, the addition of booster sessions and guidelines for teachers to adapt the program to students of different levels within Intermediate Vocational Education. Moreover, in order to have an impact on a national level, strategies need to be employed to reach high numbers of students and, therefore, support on a higher level is needed (both within schools and at policy level).

CET Conclusion
Solid-organ transplantation is the treatment of choice for end-stage organ failure. Parents of pediatric transplant recipients who reported a lack of readiness for discharge had more difficulty coping and managing their child's medically complex care at home. In this paper, we describe the protocol for the pilot study of a mHealth intervention (myFAMI). The myFAMI intervention is based on the Individual and Family Self-Management Theory and focuses on family self-management of pediatric transplant recipients at home. The purpose of the pilot study is to test the feasibility of the myFAMI intervention with family members of pediatric transplant recipients and to test the preliminary efficacy on postdischarge coping through a randomized controlled trial. The sample will include 40 family units, 20 in each arm of the study, from three pediatric transplant centers in the United States. Results from this study may advance nursing science by providing insight for the use of mHealth to facilitate patient/family-nurse communication and family self-management behaviors for family members of pediatric transplant recipients. |

CET Conclusion
BACKGROUND:
Young-adult heart transplant recipients transferring to adult care are at risk for poor health outcomes. We conducted a pilot randomized controlled trial to determine the feasibility of and to test a transition intervention for young adults who underwent heart transplantation as children and then transferred to adult care. METHODS:Participants were randomized to the transition intervention (4 months long, focused on heart-transplant knowledge, self-care, self-advocacy, and social support) or usual care. Self-report questionnaires and medical records data were collected at baseline and 3 and 6 months after the initial adult clinic visit. Longitudinal analyses comparing outcomes over time were performed using generalized estimating equations and linear mixed models. RESULTS:Transfer to adult care was successful and feasible (ie, excellent participation rates). The average patient standard deviation of mean tacrolimus levels was similar over time in both study arms and < 2.5, indicating adequate adherence. There were no between-group or within-group differences in percentage of tacrolimus bioassays within target range (> 50%). Average overall adherence to treatment was similarly good in both groups. Rates of appointment keeping through 6 months after transfer declined over time in both groups. CONCLUSIONS:The feasibility of the study was demonstrated. Our transition intervention did not improve outcomes. |
