Post-traumatic growth among pediatric transplant recipients and their caregivers: A scoping review.

BACKGROUND: Pediatric transplantation can be a stressful process for patients and caregivers. Some individuals may experience post-traumatic stress symptoms (PTSS) and post-traumatic growth (PTG) as a result. Although post-traumatic stress disorder (PTSD) has been well-studied in this population, the purpose of the present scoping review is to provide a first synthesis of the existing literature on PTG in pediatric transplant populations. METHODS: We conducted a literature search of PsycINFO and Scopus in May 2023. Eligible articles must have included a sample of solid organ transplant (SOT) or stem cell transplant (SCT) recipients under age 18, siblings of recipients, or caregivers; and must have examined PTG. RESULTS: Twenty-three studies were identified, and nine studies met inclusion criteria and were included in the review (n = 5 cross sectional; n = 4 qualitative). Cross-sectional studies examined demographic, mental health, and medical correlates of PTG in children and caregivers. PTG was correlated with PTSS among caregivers. Qualitative studies identified themes along each of the five factors of PTG. CONCLUSION: Findings overwhelmingly focused on caregiver PTG. Qualitative study findings align with the theoretical model of PTG. Additional research is needed to investigate PTG in siblings of children with a transplant and associations between PTG and medication adherence. This scoping review provides insight into positive change processes following a transplant among children and their caregivers.

The improving Medication Adherence in Adolescents and young adults following Liver Transplantation (iMALT) multisite trial: Design and trial implementation considerations.

BACKGROUND/AIMS: Medication non-adherence is a leading cause of transplant rejection, organ loss, and death; yet no rigorous controlled study to date has shown compelling clinical benefits from an adherence-improving intervention. Non-adherent patients are less likely to participate in trials, and therefore, most studies enroll a majority of adherent patients who do not stand to benefit from the intervention, as they do not have the condition (non-adherence) under investigation. The improving Medication Adherence in adolescent Liver Transplant recipients trial specifically targets non-adherent patients to investigate whether a remote intervention to improve adherence results in reduced incidence of biopsy-confirmed rejection. METHODS: Improving Medication Adherence in adolescent Liver Transplant is a randomized single-blind controlled multisite, multinational National Institutes of Health-funded trial involving 13 pediatric transplant centers in the United States and Canada. An innovative, objective adherence biomarker-the Medication Level Variability Index, which is the standard deviation of a series of medication blood levels for each patient, is used to identify non-adherent patients at risk for rejection. The index is computed using electronic health record information for all potentially eligible patients based on repeated reviews of the entire clinic's roster. Identified patients, after consent, are randomized to intervention versus control (treatment as usual) arms. The remote intervention is delivered for 2 years by trained interventionists who reside in various locations in the United States. The primary outcome is the incidence of biopsy-confirmed acute cellular rejection, as confirmed by a majority vote of three pathologists who are masked to the study allocation and clinical information. DISCUSSION: Improving Medication Adherence in adolescent Liver Transplant includes several innovative design elements. The use of a validated, objective adherence index to survey a large cohort of transplant recipients allows the teams to avoid bias inherent in both convenience sampling and referral-based recruitment and enroll only patients whose computed index indicates substantially increased risk of rejection. The remote intervention paradigm helps to engage patients who are by definition hard to engage. The use of an objective, masked medical (rather than behavioral) outcome measure reduces the likelihood of biases related to clinical information and ensures broad acceptance by the field. Finally, monitoring for potential adverse events related to increased medication exposure due to the adherence intervention acknowledges that a successful intervention (increasing adherence) could have detrimental side effects via increased exposure to and potential toxicity of the medication. Such monitoring is almost never attempted in clinical trials evaluating adherence interventions.

Substance use and solid organ transplantation in adolescents and young adults: Current findings and implications.

BACKGROUND: Understanding the role of substance use is important in the equitable allocation of solid organs and may present an opportunity for improving outcomes among substance users who receive transplants. This scoping review presents findings related to substance use among pediatric and young adult transplant populations and suggests future directions. METHODS: A scoping review was conducted seeking studies related to substance use in pediatric and young adult transplant populations under the age of 39 years. Studies were deemed eligible if they collected data or addressed policy concerns and participants' mean age was below 39 years. RESULTS: Twenty-nine studies were identified as eligible for this review. Overall, policies around substance use are largely inconsistent throughout both pediatric and adult transplant centers. Findings indicated that substance use among pediatric and young adult transplant recipients is similar to or lower than healthy peers. Few studies addressed marijuana use and opioid misuse, among other substances. CONCLUSIONS: There is a general dearth of research on substance use in this population. The current findings suggest that substance use, although relatively less common, affects eligibility for transplant, may lead to poor outcomes, and affects medication adherence. Inconsistent substance use policies in transplant centers have the potential to result in bias. However, more research is needed on the effects of substance use among pediatric and young adult transplant candidates and recipients as well as on equitable policies for organ allocation for individuals who use substances.

Students for others: Correlates of adherence to COVID-19 guidelines.

Objective: The present study aimed to determine correlates of adherence to COVID-19 health precautions among college students. Drawing from the literature, the following constructs were considered: self-efficacy, conscientiousness, social support, collectivism, empathy, and fear of COVID. Participants: Undergraduate students (N = 92) recruited from psychology classes and social media, living on and off-campus, served as participants during fall 2020. Methods: Participants completed a short self-report survey, delivered online, measuring adherence to COVID-19 health precautions and its possible correlates. Results: After preliminary comparisons showing no differences in adherence between students living on and off-campus, linear regression analyses of the complete sample revealed that the significant predictors of adherence were conscientiousness, collectivism, empathy, and fear of COVID. Conclusions: College student adherence was largely driven by interpersonal motivators coupled with a modest level of fear, rather than more general constructs. These findings offer implications for considering targets in public health campaigns delivered to college students.

Acceleration of mobile health for monitoring post-transplant in the COVID-19 era: Applications for pediatric settings.

BACKGROUND: Since the start of the COVID-19 pandemic and consequent lockdowns, the use of telehealth interventions has rapidly increased both in the general population and among transplant recipients. Among pediatric transplant recipients, this most frequently takes the form of interventions on mobile devices, or mHealth, such as remote visits via video chat or phone, phone-based monitoring, and mobile apps. Telehealth interventions may offer the opportunity to provide care that minimizes many of the barriers of in-person care. METHODS: The present review followed the PRISMA guidelines. Sources up until October 2020 were initially identified through searches of PsycInfo® and PubMed® . RESULTS: We identified ten papers that reported findings from adult interventions and five studies based in pediatrics. Eight of the adult publications stemmed from the same two trials; within the pediatric subset, this was the case for two papers. Studies that have looked at mHealth interventions have found high acceptability rates over the short run, but there is a general lack of data on long-term use. CONCLUSIONS: The literature surrounding pediatric trials specifically is sparse with all findings referencing interventions that are in early stages of development, ranging from field tests to small feasibility trials. The lack of research highlights the need for a multi-center RCT that utilizes robust measures of medication adherence and other outcome variables, with longer-term follow-up before telehealth interventions should be fully embraced.

Posttraumatic stress and medication adherence in pediatric transplant recipients.

Adolescent transplant recipients may encounter a range of potentially traumatic events (PTEs) pre- and posttransplant, yet little is known about the relationship between posttraumatic stress symptoms (PTSS) and medication adherence in this population. In the present study, adolescent recipients and caregivers completed psychosocial questionnaires at enrollment. Outpatient tacrolimus trough level data were collected over 1 year to calculate the Medication Level Variability Index (MLVI), a measure of medication adherence. Nonadherence (MLVI ≥2) was identified in 34.8% of patients, and most (80.7%) reported ≥1 PTE exposure. Levels of PTSS indicating likely posttraumatic stress disorder (PTSD) were endorsed by 9.2% of patients and 43.7% of caregivers. PTSS and MLVI were significantly correlated in the liver subgroup (r = .30, p = .04). Hierarchical multivariable linear regression analyses revealed overall patient PTSS were significantly associated with QoL (p < .001). PTEs are common in adolescent recipients; a minority may meet criteria for PTSD. PTSS screening to identify nonadherence risk requires further investigation and addressing PTSS may improve QoL. Caregivers appear at greater risk for PTSD and may require their own supports. The study was approved by each participating center's Institutional Review Board.

Remote intervention engagement and outcomes in the Clinical Trials in Organ Transplantation in Children consortium multisite trial.

Remote interventions are increasingly used in transplant medicine but have rarely been rigorously evaluated. We investigated a remote intervention targeting immunosuppressant management in pediatric lung transplant recipients. Patients were recruited from a larger multisite trial if they had a Medication Level Variability Index (MLVI) ≥2.0, indicating worrisome tacrolimus level fluctuation. The manualized intervention included three weekly phone calls and regular follow-up calls. A comparison group included patients who met enrollment criteria after the subprotocol ended. Outcomes were defined before the intent-to-treat analysis. Feasibility was defined as ≥50% of participants completing the weekly calls. MLVI was compared pre- and 180 days postenrollment and between intervention and comparison groups. Of 18 eligible patients, 15 enrolled. Seven additional patients served as the comparison. Seventy-five percent of participants completed ≥3 weekly calls; average time on protocol was 257.7 days. Average intervention group MLVI was significantly lower (indicating improved blood level stability) at 180 days postenrollment (2.9 ± 1.29) compared with pre-enrollment (4.6 ± 2.10), p = .02. At 180 days, MLVI decreased by 1.6 points in the intervention group but increased by 0.6 in the comparison group (p = .054). Participants successfully engaged in a long-term remote intervention, and their medication blood levels stabilized. NCT02266888.

Approaches to Research Determination of Late Acute Cellular Rejection in Pediatric Liver Transplant Recipients.

A central pathology or site reading of biopsy slides is used in liver transplant clinical trials to determine rejection. We evaluated interrater reliability of readings of "rejection or not" using digitized slides from the Medication Adherence in Children who had a Liver Transplant (MALT) study. Four masked experienced pathologists read the digitized slides and then reread them after a study-specific histologic endpoint development program. Agreement was expressed throughout as a Kappa or Fleiss Kappa statistic (Ò¡). A Ò¡ > 0.6 was predefined as desirable. Readings were correlated with immunosuppressant adherence (the Medication Level Variability Index, [MLVI]), and maximal liver enzyme levels during the study period. Interrater agreement between site and central review in MALT, and between 4 pathologists later on, was low (Ò¡ = 0.44, Fleiss Ò¡ = 0.41, respectively). Following the endpoint development program, agreement improved and became acceptable (Ò¡ = 0.71). The final reading was better-aligned with maximal gamma-glutamyl transferase levels and MLVI as compared with the original central reading. We found substantial disagreement between experienced pathologists reading the same slides. A unique study-specific procedure improved interrater reliability to the point it was acceptable. Such a procedure may be indicated to increase reliability of histopathologic determinations in future research, and perhaps also clinically.

The Utility of a Pre-Transplant Psychosocial Evaluation in Predicting Post-Liver Transplant Outcomes.

BACKGROUND: There is insufficient evidence about the ability of pretransplant psychosocial evaluations to predict posttransplant outcomes. While standardized assessments were developed to increase predictive validity, it is unclear whether the risk scores they yield predict outcomes. We investigated if the Stanford Integrated Psychosocial Assessment for Transplantation (SIPAT), a scaling approach to those assessments, would have been a superior predictor than the standard psychosocial evaluation. METHODS: In this retrospective study, medical records of 182 adult liver transplant recipients who were at least 1 year posttransplant and prescribed tacrolimus for immunosuppression were analyzed. Regression analyses predicted outcomes of interest, including immunosuppressant nonadherence and biopsy-proven rejection, obtained 1-year posttransplant to time of data collection. Nonadherence was determined using the medication level variability index (MLVI). RESULTS: Approximately 49% of patients had MLVI > 2.5, suggestive of nonadherence, and 15% experienced rejection. SIPAT total score did not predict adherence either using the continuous (P = .70), or dichotimized score, above or below > 2.5 (P = .14), or rejection (P = 0.87). Using a SIPAT threshold (total score > 69) did not predict adherence (p = .16) nor was a superior predictor of the continuous adherence score (P = .45), MLVI > 2.5 (P = .42), or rejection (P = 0.49), than the standard evaluation. CONCLUSION: Our findings suggest that the SIPAT is unable to predict 2 of the most important outcomes in this population, immunosuppressant adherence and rejection. Research efforts should attempt to evaluate the best manner to use psychosocial evaluations.

Adherence to Medication During Transition to Adult Services.

The transition from childhood and adolescence to adulthood is often tumultuous. For individuals with a chronic medical condition, this progression also includes a gradual transition to independence in healthcare management as well as a transfer in care location at some set point. As adolescents navigate these sometimes challenging processes, there is a significant risk for a decline in adequate health behaviors, which can have dire consequences. One of the most vital components of the transfer to adult care is medication adherence. Poor medication adherence puts patients at risk for worse outcomes, with the most profound being increased mortality for many conditions. In recent years, acknowledgment of the need to create evidence-based methods to aid patients during the transition period has been growing. This paper seeks to provide an overview of current research and recommendations for interventions to increase adherence to medication regimens during this period.

The impact of caregiver post-traumatic stress and depressive symptoms on pediatric transplant outcomes.

PTSS as well as symptoms of depression have been reported in children who experience a serious medical adversity as well as their caretakers. The adverse effects of PTSS, when experienced by the patients, on medical outcomes have been clearly documented. However, the impact of those symptoms, if any, when experienced by the caretakers on child outcomes has not been investigated prospectively. We evaluated whether caregiver PTSS and depression symptoms predict adherence to medications and medical outcomes in a prospective multisite study. Four hundred children participated in MALT. Caretaker PTSS were assessed by the IES and depressive symptoms by CES-D. During 2 years of follow-up, the MLVI was used to determine adherence. Centrally read, biopsy-confirmed organ rejection was the primary medical outcome. IES scores were not associated with either adherence or rejection outcomes. In contrast, there were significant correlations between CES-D (depression) scores and lower adherence, r = .13, P < .001, and a trend toward higher scores on the CES-D among those whose children had experienced rejection, 12.4 (SD = 10.9) versus 9.1 (SD = 8.6), P = .077. Caregivers' PTSS were not a risk factor for poor child outcomes in this cohort, whereas depression symptoms were associated with non-adherence and possibly increased rates of rejection. Further study can validate if caregivers' depression as opposed to PTSS confers greater risk and should be a focus during the clinical care of medically ill children.

Examining the Psychosocial Needs of Adolescents With Craniofacial Conditions: A Mixed-Methods Approach.

OBJECTIVE: To determine, for intervention development, the psychosocial needs of adolescents diagnosed with a craniofacial condition who attended focus group sessions. DESIGN: A mixed-methods design combining qualitative focus groups with quantitative measures. SETTING: An outpatient clinic at a major medical center in Manhattan, New York. PARTICIPANTS: Fourteen adolescents, aged 14 to 18, with craniofacial conditions. MAIN MEASURES: Participants completed measures assessing a range of psychological constructs. Average scores were compared to clinical cutoff scores and normative data for adolescents. The 2 focus groups were coded using an inductive approach to assess pertinent themes. Additionally, the acceptability and feasibility of a proposed intervention was measured. RESULTS: Adolescents with craniofacial conditions were within normal ranges for quality of life, self-esteem, and body image and they reported higher resiliency. They were above cutoff scores for perceived stress and post-traumatic stress disorder symptoms and below cutoff scores for mindfulness. When compared to normative samples, they displayed higher perceived social support, but lower coping. Based on qualitative analyses, 6 themes emerged: stress, bullying, coping, resiliency, mindfulness, and social support. Both qualitative and quantitative analyses revealed most participants were supportive of a future intervention for this population. CONCLUSIONS: The present study identified several factors associated with psychological well-being of adolescents with craniofacial diagnoses and demonstrates the importance of creating interventions to target specific psychosocial needs. Findings from this study may guide researchers in developing and refining a specific program for this population and provide information to help those with craniofacial conditions who are experiencing psychosocial challenges.

Peak Growth Hormone Response to Combined Stimulation Test in 315 Children and Correlations with Metabolic Parameters.

BACKGROUND/AIMS: Studies are lacking regarding the timing of peak growth hormone (PGH) response. We aim to elucidate the timing of PGH response to arginine and levodopa (A-LD) and evaluate the influence of body mass index (BMI) and other metabolic parameters on PGH. METHODS: During growth hormone (GH) stimulation testing (ST) with A-LD, serum GH was measured at baseline and every 30 min up to 180 min. The PGH cut-off was defined as &#x3c;10 ng/mL. IGF-1, IGF BP3, BMI, and metabolic parameters were obtained in a fasting state at baseline. RESULTS: In the 315 tested children, stimulated PGH levels occurred at or before 120 min in 97.8% and at 180 min in 2.2%. GH area under the curve (AUC) positively correlated with PGH in all patients and with IGF-1 in pubertal males and females. BMI negatively correlated with PGH in all subjects. GH AUC negatively correlated with HOMA-IR and total cholesterol. CONCLUSION: We propose termination of the GH ST with A-LD at 120 min since omission of GH measurement at 180 min did not alter the diagnosis of GH deficiency based on a cut-off of &#x3c; 10 ng/mL. BMI should be considered in the interpretation of GH ST with A-LD. The relationships between GH AUC and metabolic parameters need further study.

Assessment and Treatment of Nonadherence in Transplant Recipients.

Stable intake of an immunosuppressant medication regimen is essential for posttransplant survival in the vast majority of cases. And yet, many patients are nonadherent (do not take their medications as prescribed), and suffer consequences ranging from rejection to morbidity and mortality. We review the evidence related to monitoring of adherence to medications, and intervention strategies. Our aim is to provide a baseline from which readers may approach behavioral aspects of posttransplant care. This review may also help readers in designing clinical programs for routine monitoring of adherence, and inform the choice of intervention when adherence falls below a certain threshold.

Risky business: is pubic hair removal by women associated with body image and sexual health?

Background Body hair removal is a behaviour that has become normative among women in Westernised cultures, and is presented by the media as the feminine ideal, despite being painful and a potential cause of infection. Of concern, removal may be part of a more global pattern of appearance dissatisfaction and risky sexual behaviour. The aim of the present study was to examine the relationships among pubic hair removal, body image and sexual health indicators. METHODS: Women (n=264; Mage=33.82, s.d.=11.13, range=18-66) completed self-report questionnaires assessing these constructs, including an assessment of body hair removal practices. RESULTS: Greater appearance concerns (as measured by thin-ideal internalisation, appearance investment and self-objectification) and sexual health indicators (i.e. less condom use self-efficacy when a partner disapproves of condom use) all predicted greater importance of reasons for pubic hair removal (R2=0.315, F(8184)=9.97, P<0.001), controlling for age groups. Additionally, women who removed a greater amount of hair reported more thin-ideal internalisation and appearance investment than those who removed less hair. CONCLUSIONS: Women who express stronger reasoning for pubic hair removal, and remove a larger amount of it, may endorse problematic beliefs and behaviours particularly related to appearance concerns. It is important for practitioners to consider this practice as distinct from grooming and to be aware of its association with a broader array of risky beliefs and behaviours that can compromise women's well-being.

Pediatric Liver Transplant Teams Coping With Patient Death.

OBJECTIVES: Coping with patient death among pediatric liver transplant teams has received little attention despite general recognition of the potentially negative emotional consequences associated with such loss. The purpose of this study was to investigate the ways in which members of pediatric liver transplant teams cope with the death of patients on the waitlist and post-transplant and the institutional resources available to facilitate this coping. METHODS: Participants included 120 physicians, nurses, and mental health professionals from multiple transplant centers across the United States. Participants completed an online questionnaire that assessed the availability of formal coping resources at their institutions, informal sources of support used to cope with patient death, and as indices of coping, bereavement, and emotional exhaustion symptoms experienced. RESULTS: Debriefing, the most commonly offered support, was available to about half (55.8%) of the sample; yet, nearly all respondents (98.3%) indicated that debriefing would be useful. On average, bereavement and emotional exhaustion levels were comparable to normative data, but patterns of coping varied based on participants' position within the transplant team. For participants who reported that debriefing was available at their institutions, emotional exhaustion was lower. CONCLUSIONS: Overall, formal supports were inconsistently offered to pediatric transplant team members. Team members expressed high acceptability for debriefing, which has been associated with benefits in other populations, and findings indicated better coping in the transplant setting when it was offered.

Estimating correlations among cardiovascular patients' psychiatric and physical symptom indicators: The biplot in correspondence analysis approach.

OBJECTIVES: We employed the correspondence analysis (CA) biplot to estimate correlations between gender-age levels of cardiovascular disease patients and their psychiatric and physical symptoms. Utilization of this correlation estimation can inform clinical practice by elucidating associations between certain psychiatric or physical symptoms and specific gender-age levels. METHOD: The CA biplot utilized here was designed to visually inspect row-column category associations in a 2-dimensional plane and then to numerically estimate the category associations with correlations. To do so, we (a) estimated dimensions from row and column categories with CA; (b) verified statistical significance of dimensions with a permutation test; (c) projected row and column categories in a plan constructed with the first 2 dimensions that were statistically significant; (d) visually inspected category associations in the plane; and (e) numerically estimated category associations with correlations. RESULTS: Consistent with the previous results, female cardiovascular disease patients were more likely to experience psychiatric symptoms than the male patients. However, when examining the results by gender and age, both female and male patients in their 50s and 60s tended to experience elevated rates of the psychiatric symptoms. CONCLUSIONS: The CA biplot can be useful for isolating key clinical concerns among any medical populations.
