RESUMO
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.

N-acetylcysteine (NAC) may serve as a novel pharmacotherapy for substance use and substance craving in individuals with substance use disorders (SUDs), possibly through its potential to regulate glutamate. Though prior meta-analyses generally support NAC's efficacy in reducing symptoms of craving, individual trials have found mixed results. The aims of the this updated meta-analysis were to (1) examine the efficacy of NAC in treating symptoms of craving in individuals with a SUD and (2) explore subgroup differences, risk of bias, and publication bias across trials. Database searches of PubMed, Cochrane Library, and ClinicalTrials.gov were conducted to identify relevant randomized control trials (RCTs). The meta-analysis consisted of 9 trials which analyzed data from a total of 623 participants. The most targeted substance in the clinical trials was alcohol (3/9; 33.3%), followed by tobacco (2/9; 22.2%) and multiple substances (2/9; 22.2%). Meta-analysis, subgroup analyses, and leave-one-out analyses were conducted to examine treatment effect on craving symptoms and adverse events (AEs). Risk of bias assessments, Egger's tests, and funnel plot tests were conducted to examine risk of bias and publication bias. NAC did not significantly outperform placebo in reducing symptoms of craving in the meta-analysis (SMD = 0.189, 95% CI = -0.015 - 0.393). Heterogeneity was very high in the meta-analysis (99.26%), indicating that findings may have been influenced by clinical or methodological differences in the study protocols. Additionally, results indicate that there may be publication bias present. There were no between-group differences in risk of AEs. Overall, our findings are contrary to those of prior meta-analyses, suggesting limited impact of NAC on substance craving. However, the high heterogeneity and presence of publication bias identified warrants cautious interpretation of the meta-analytic outcomes.
RESUMO
INTRODUCTION: This study investigated the acceptability and feasibility of digital phenotyping in a military sample with a history of traumatic brain injury and co-occurring psychological and cognitive symptoms. The first aim was to evaluate the acceptability of digital phenotyping by (1a) quantifying the proportion of participants willing to download the app and rates of dropout and app discontinuation and (1b) reviewing the stated reasons for both refusing and discontinuing use of the app. The second aim was to investigate technical feasibility by (2a) characterizing the amount and frequency of transferred data and (2b) documenting technical challenges. Exploratory aim 3 sought to leverage data on phone and keyboard interactions to predict if a participant (a) is depressed and (b) has depression that improves over the course of the study. MATERIALS AND METHODS: A passive digital phenotyping app (Mindstrong Discovery) functioned in the background of the participants' smartphones and passively collected phone usage and typing kinematics data. RESULTS: Fifteen out of 16 participants (93.8%) consented to install the app on their personal smartphone devices. Four participants (26.7%) discontinued the use of the app partway through the study, primarily because of keyboard usability and technical issues. Fourteen out of 15 participants (93.3%) had at least one data transfer, and the median number of days with data was 40 out of a possible 57 days. The exploratory machine learning models predicting depression status and improvement in depression performed better than chance. CONCLUSIONS: The findings of this pilot study suggest that digital phenotyping is acceptable and feasible in a military sample and provides support for future larger investigations of this technology.
