When Should I Get My Next COVID-19 Vaccine? Data From the Surveillance of Responses to COVID-19 Vaccines in Systemic Immune-Mediated Inflammatory Diseases (SUCCEED) Study.

OBJECTIVE: To determine how serologic responses to coronavirus disease 2019 (COVID-19) vaccination and infection in immune-mediated inflammatory disease (IMID) are affected by time since last vaccination and other factors. METHODS: Post-COVID-19 vaccination, data, and dried blood spots or sera were collected from adults with rheumatoid arthritis, inflammatory bowel disease, systemic lupus erythematosus, ankylosing spondylitis and spondylarthritis, and psoriasis and psoriatic arthritis. The first sample was collected at enrollment, then at 2 to 4 weeks and 3, 6, and 12 months after the latest vaccine dose. Multivariate generalized estimating equation regressions (including medications, demographics, and vaccination history) evaluated serologic response, based on log-transformed anti-receptor-binding domain (RBD) IgG titers; we also measured antinucleocapsid (anti-N) IgG. RESULTS: Positive associations for log-transformed anti-RBD titers were seen with female sex, number of doses, and self-reported COVID-19 infections in 2021 to 2023. Negative associations were seen with prednisone, anti-tumor necrosis factor agents, and rituximab. Over the 2021-2023 period, most (94%) of anti-N positivity was associated with a self-reported infection in the 3 months prior to testing. From March 2021 to February 2022, anti-N positivity was present in 5% to 15% of samples and was highest in the post-Omicron era, with antinucleocapsid positivity trending to 30% to 35% or higher as of March 2023. Anti-N positivity in IMID remained lower than Canada's general population seroprevalence (> 50% in 2022 and > 75% in 2023). Time since last vaccination was negatively associated with log-transformed anti-RBD titers, particularly after 210 days. CONCLUSION: Ours is the first pan-Canadian IMID assessment of how vaccine history and other factors affect serologic COVID-19 vaccine responses. These findings may help individuals personalize vaccination decisions, including consideration of additional vaccination when > 6 months has elapsed since last COVID-19 vaccination/infection.

Adherence to caregiver-administered intravenous immunosuppressant medications in pediatric hematopoietic stem cell transplant.

BACKGROUND: The purpose of this study was to describe taking, timing, and dosing adherence to home caregiver-administered intravenous (IV) immunosuppressants in a sample of pediatric hematopoietic stem cell transplant (HCT) recipients. PROCEDURES: Sixteen children who had undergone HCT, ages 3 months to 15 years, and their caregivers participated. All caregivers were biological mothers. Caregivers completed a demographic questionnaire as part of a larger study and brought in portable infusion pumps to download the pump data at the time of their child's post-HCT clinic visit. Pump data were then examined for dose taking, timing, and amount for 30 days following discharge. RESULTS: Despite the importance of the precise timing of IV immunosuppressants, adherence taking, dosing, and timing varied widely in this sample. The mean percentage of doses administered was 98.72%, and 81.3% of children received all doses of immunosuppressant. However, only 62% of doses were given on time and the mean difference between the prescribed and actual administration time was 67.03 minutes. CONCLUSIONS: Although taking adherence was high, the timing and dosing adherence to IV immunosuppressants in the home was poor. Additional support to promote adherence should be provided including assisting caregivers to identify and use adherence strategies specific to their child's IV immunosuppressant regimen in the home.

Recommendations for the surveillance of mental health problems in childhood, adolescent, and young adult cancer survivors: a report from the International Late Effects of Childhood Cancer Guideline Harmonization Group.

Survivors of childhood, adolescent, and young adult (diagnosed when <25 years of age) cancer are at risk of mental health problems. The aim of this clinical practice guideline is to harmonise international recommendations for mental health surveillance in survivors of childhood, adolescent, and young adult cancer. This guideline was developed by a multidisciplinary panel of experts under the sponsorship of the International Guideline Harmonization Group. We evaluated concordance among existing survivorship clinical practice guidelines and conducted a systematic review following evidence-based methods. Of 7249 studies identified, 76 articles from 12 countries met the inclusion criteria. Recommendations were formulated on the basis of identified evidence in combination with clinical considerations. This international clinical practice guideline strongly recommends mental health surveillance for all survivors of childhood, adolescent, and young adult cancers at every follow-up visit and prompt referral to mental health specialists when problems are identified. Overall, the recommendations reflect the necessity of mental health surveillance as part of comprehensive survivor-focused health care.

Influence of Digital Intervention Messaging on Influenza Vaccination Rates Among Adults With Cardiovascular Disease in the United States: Decentralized Randomized Controlled Trial.

BACKGROUND: Seasonal influenza affects 5% to 15% of Americans annually, resulting in preventable deaths and substantial economic impact. Influenza infection is particularly dangerous for people with cardiovascular disease, who therefore represent a priority group for vaccination campaigns. OBJECTIVE: We aimed to assess the effects of digital intervention messaging on self-reported rates of seasonal influenza vaccination. METHODS: This was a randomized, controlled, single-blind, and decentralized trial conducted at individual locations throughout the United States over the 2020-2021 influenza season. Adults with self-reported cardiovascular disease who were members of the Achievement mobile platform were randomized to receive or not receive a series of 6 patient-centered digital intervention messages promoting influenza vaccination. The primary end point was the between-group difference in self-reported vaccination rates at 6 months after randomization. Secondary outcomes included the levels of engagement with the messages and the relationship between vaccination rates and engagement with the messages. Subgroup analyses examined variation in intervention effects by race. Controlling for randomization group, we examined the impact of other predictors of vaccination status, including cardiovascular condition type, vaccine drivers or barriers, and vaccine knowledge. RESULTS: Of the 49,138 randomized participants, responses on the primary end point were available for 11,237 (22.87%; 5575 in the intervention group and 5662 in the control group) participants. The vaccination rate was significantly higher in the intervention group (3418/5575, 61.31%) than the control group (3355/5662, 59.25%; relative risk 1.03, 95% CI 1.004-1.066; P=.03). Participants who were older, more educated, and White or Asian were more likely to report being vaccinated. The intervention was effective among White participants (P=.004) but not among people of color (P=.42). The vaccination rate was 13 percentage points higher among participants who completed all 6 intervention messages versus none, and at least 2 completed messages appeared to be needed for effectiveness. Participants who reported a diagnosis of COVID-19 were more likely to be vaccinated for influenza regardless of treatment assignment. CONCLUSIONS: This personalized, evidence-based digital intervention was effective in increasing vaccination rates in this population of high-risk people with cardiovascular disease. TRIAL REGISTRATION: ClinicalTrials.gov NCT04584645; https://clinicaltrials.gov/ct2/show/NCT04584645.

The comfort ability program for adolescents with sickle cell pain: Evaluating feasibility and acceptability of an inpatient group-based clinical implementation.

BACKGROUND: Integration of nonpharmacological therapies, such as cognitive and behavioral pain management strategies, is recommended to support comprehensive disease and pain management among children and adolescents with sickle cell disease (SCD). The Comfort Ability Program for Sickle Cell Pain (CAP for SCP) introduces psychological and biobehavioral pain management strategies to children and adolescents with SCD. This study aimed to pilot the implementation of the CAP for SCP in a group setting to children and adolescents hospitalized for SCD pain examining feasibility, acceptability, and preliminary effectiveness on improving pain knowledge and coping efficacy. METHOD: Adaptation of CAP for SCP into a three-session group format was guided by four phases of the Dynamic Adaptation Process model: Exploration, Preparation, Implementation, and Sustainment. Youth with SCD (n = 57) hospitalized for pain participated in at least one session and completed self-report of knowledge of pain management skills, pain coping efficacy, and treatment acceptance. Completion rates of sessions and qualitative feedback were gathered to evaluate feasibility and acceptability. RESULTS: Feasibility of conducting inpatient group sessions was suboptimal; however, patients and medical providers reported moderate to high levels of treatment acceptance. Patients also reported significant improvements in knowledge of pain management skills following session 1. CONCLUSIONS: CAP for SCP is a patient-centered first-line psychoeducational intervention that can be integrated into clinical practice settings to introduce youth to cognitive and behavioral pain management strategies to support SCD pain management.

Caregiver-reported outcomes of pediatric transplantation: Changes and predictors at 6 months post-transplant.

BACKGROUND: It is widely assumed that pediatric solid organ transplantation results in better caregiver-reported outcomes, including reduced caregiver psychological distress and increased child health-related quality of life (HRQOL), yet little empirical evidence of this expectation exists. The current investigation aims to fill this gap and identify key clinical course factors predictive of caregiver-reported outcomes. METHODS: Forty-nine caregivers of children (Mage  = 10.30 years, SD = 5.43) presenting for kidney, liver, or heart transplant evaluation reported on their psychological distress levels (anxiety, depression, somatization, and global psychological stress) and their children's HRQOL at children's pretransplant evaluations and 6 months post-transplant. Clinical course factors were abstracted via medical chart review. RESULTS: Caregivers did not report significant changes in their psychological distress from pre- to post-transplant but reported significantly improved child HRQOL across most domains (ds = -.45 to -.54). Higher post-transplant caregiver global psychological distress was predicted by older child age, shorter time since diagnosis, and lower pretransplant caregiver-reported child HRQOL even after controlling for pretransplant caregiver psychological distress. Lower post-transplant child total HRQOL was predicted by more post-transplant hospitalizations even after controlling for pretransplant child total HRQOL. CONCLUSIONS: These preliminary results indicate pediatric solid organ transplantation was associated with some improved caregiver-reported outcomes, specifically children's HRQOL, but not caregivers' psychological distress. Linear regression models identify several clinical course and pretransplant factors associated with transplantation outcomes. Characterizing how caregivers view their psychological distress levels and children's HRQOL across the transplantation process could inform family-centered holistic care and support caregiver adaptation to transplantation.

Psychosocial Functioning Among Caregivers of Childhood Cancer Survivors Following Treatment Completion.

OBJECTIVE: To inform efforts to better support caregivers of children with cancer during the transition from treatment to survivorship, this study sought to characterize caregiver mental health-related quality of life (HRQOL) and anxiety, and examine the influence of family psychosocial risk and caregiver problem-solving on these outcomes. METHOD: Participants included 124 caregivers (child age M = 10.05 years; SD = 4.78), 12-19 months from the conclusion of cancer-directed treatment. Participants' self-reported mental HRQOL, anxiety, and problem-solving were compared with community norms using t-tests. Correlations and hierarchical multiple regressions examined the influence of psychosocial risk and problem-solving on caregiver mental HRQOL and anxiety. RESULTS: Overall, caregivers reported HRQOL and anxiety within normal limits. Caregivers also reported more adaptive patterns of problem-solving than community norms. Subsets of caregivers reported clinical levels of psychosocial risk (11%) and at-risk levels of mental HRQOL (2.5%) and anxiety (5.7%). Females reported greater anxiety than males. Psychosocial risk and negative problem orientation (NPO) were both related to poorer mental HRQOL and greater anxiety (r = .40-.51, p's < .001). Positive problem orientation related to better mental HRQOL and lower anxiety (r = .18-.21, p's < .05). Impulsivity/carelessness and avoidance were associated with greater anxiety (r = .19-.25, p's < .05). Only NPO accounted for additional variance in mental HRQOL and anxiety, over and above psychosocial risk and demographic characteristics. CONCLUSIONS: The majority of caregivers appear to be resilient and experience limited distress during the off therapy period. Targeting negative cognitive appraisals (NPO) through cognitive-behavioral therapy or problem-solving skills training may further improve caregiver psychosocial functioning.

Adherence Barriers for Adolescent and Young Adult Transplant Recipients: Relations to Personality.

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.

Caregivers' Barriers to Facilitating Medication Adherence in Adolescents/Young Adults With Solid Organ Transplants: Measure Development and Validation.

OBJECTIVE: To evaluate the factor structure, validity, and reliability of the Caregiver Medication Barriers to Adherence Scale (CMBAS), which assesses caregivers' barriers to facilitating medication adherence in adolescent and young adults (AYAs) with solid organ transplants. METHODS: The sample included 93 caregivers of AYAs ages 12-22 years who received a liver, kidney, or heart transplant. Caregivers completed the CMBAS and surveys to assess its validity, including internalizing symptoms, personality traits (i.e., neuroticism, conscientiousness), and AYAs' nonadherence to immunosuppressant medications. AYA nonadherence to tacrolimus was objectively assessed via the Medication Level Variability Index (MLVI). RESULTS: Confirmatory factor analyses of the CMBAS revealed a two-factor model: Caregiver Emotional Distress and Caregiver Cognitive Burden/Responsibility. Higher CMBAS scores were related to higher levels of caregiver internalizing symptoms (rs = .28 to .30), neuroticism (r = .27), and caregiver proxy-reported immunosuppressant nonadherence (r = .27), as well as lower levels of caregiver conscientiousness (rs = -.25 to -.26). The CMBAS was not associated with the MLVI (rs = -.13 to -.16). CONCLUSIONS: The CMBAS demonstrated reliability and validity for caregivers of AYAs with solid organ transplants. Findings support the use of the CMBAS as a brief clinical screening tool to identify caregivers' barriers to facilitating AYA medication adherence.

Neural Integration of Stimulus History Underlies Prediction for Naturalistically Evolving Sequences.

Forming valid predictions about the environment is crucial to survival. However, whether humans are able to form valid predictions about natural stimuli based on their temporal statistical regularities remains unknown. Here, we presented subjects with tone sequences with pitch fluctuations that, over time, capture long-range temporal dependence structures prevalent in natural stimuli. We found that subjects were able to exploit such naturalistic statistical regularities to make valid predictions about upcoming items in a sequence. Magnetoencephalography (MEG) recordings revealed that slow, arrhythmic cortical dynamics tracked the evolving pitch sequence over time such that neural activity at a given moment was influenced by the pitch of up to seven previous tones. Importantly, such history integration contained in neural activity predicted the expected pitch of the upcoming tone, providing a concrete computational mechanism for prediction. These results establish humans' ability to make valid predictions based on temporal regularities inherent in naturalistic stimuli and further reveal the neural mechanisms underlying such predictive computation.SIGNIFICANCE STATEMENT A fundamental question in neuroscience is how the brain predicts upcoming events in the environment. To date, this question has primarily been addressed in experiments using relatively simple stimulus sequences. Here, we studied predictive processing in the human brain using auditory tone sequences that exhibit temporal statistical regularities similar to those found in natural stimuli. We observed that humans are able to form valid predictions based on such complex temporal statistical regularities. We further show that neural response to a given tone in the sequence reflects integration over the preceding tone sequence and that this history dependence forms the foundation for prediction. These findings deepen our understanding of how humans form predictions in an ecologically valid environment.

Knowledge of Late Effects Risks and Healthcare Responsibility in Adolescents and Young Adults Treated for Childhood Cancer.

OBJECTIVE: This study aimed to examine the level and predictors of knowledge of late effects risks from childhood cancer treatment in adolescent and young adult (AYA) survivors. METHODS: Seventy-three AYAs, aged 14-21, completed measures of knowledge of late effect risks, executive functioning, and responsibility for health self-management. Sixty-seven parents of these AYA survivors (91.7%) also participated. RESULTS: Survivors demonstrated poor knowledge of their unique risks for treatment-related late effects, with a mean accurate knowledge score of 54.29% (SD = 24.19%). The number of late effects for which survivors were at risk was negatively correlated with risk knowledge (r = -.34, p < .01). Survivors' executive functioning was not related to risk knowledge. In regression analyses, survivor age positively predicted accurate knowledge of late effects risks, and the number of late effects risk was a negative predictor. In separate models, survivor self-report of AYA responsibility for health self-management did not predict knowledge (R2 = .39, F = 10.86, p < .01), but parent proxy-report was a significant positive predictor (R2 = .38, F = 9.62, p < .01). Parental involvement was not a significant predictor in either model. CONCLUSION: There are significant knowledge gaps among AYA survivors of childhood cancer, which appear to be related to younger AYA age and lower levels of AYA responsibility for health self-management. Additional intervention is critical to increase AYA knowledge of their risk for late effects in order to promote continued engagement in long-term follow-up care and surveillance across the lifespan.

Poor Adherence Is Associated with More Infections after Pediatric Hematopoietic Stem Cell Transplant.

We prospectively examined rates of outpatient oral medication adherence in children after hematopoietic stem cell transplant (post-HSCT). For 6 months after first discharge post-HSCT, 50 patients (aged 0 to 16 years) and their primary caregivers agreed to store 1 oral medication in an electronic pill bottle that date and time stamps each bottle opening. Demographics, disease, donor type, and prescribed post-HSCT medication regimen were collected via chart review. For each patient percent adherence was calculated by dividing the number of doses taken as indicated by the electronic pill bottle by the number of doses prescribed for the same time period. Average percent adherence ranged from 63% at 1 month after discharge to 57% at 6 months after discharge. For patients who received an allogeneic transplant, lower adherence was associated (P < .005) with higher infection rates, after controlling for age and time since transplant. No such relationship was observed for patients who received an autologous transplant. This study demonstrates that poor oral medication adherence is prevalent, persistent, and, for patients receiving an allogeneic transplant, associated with increased incidence of infections during the outpatient treatment period. This study highlights the need for further research examining factors that hinder medication adherence as well as monitoring, promoting, and intervening to maximize medication adherence throughout the HSCT course.

Multimethod Assessment of Medication Nonadherence and Barriers in Adolescents and Young Adults With Solid Organ Transplants.

Objective: To (a) examine levels of medication nonadherence in adolescent and young adult (AYA) solid organ transplant recipients based on AYA- and caregiver proxy-reported nonadherence to different medication types and the medication-level variability index (MLVI) for tacrolimus, and (b) examine associations of adherence barriers and AYA and caregiver emotional distress symptoms with reported nonadherence and the MLVI. Method: The sample included 47 AYAs (M age = 16.67 years, SD = 1.74; transplant types: 25% kidney, 47% liver, 28% heart) and their caregivers (94 total participants). AYAs and caregivers reported on AYAs' adherence barriers and their own emotional functioning. Nonadherence was measured with AYA self- and caregiver proxy-report and the MLVI for tacrolimus. Results: The majority of AYAs and caregivers denied nonadherence, with lower rates of nonadherence reported for antirejection medications. In contrast, 40% of AYAs' MLVI values indicated nonadherence to tacrolimus. AYAs and caregivers who verbally acknowledged nonadherence had more AYA barriers and greater caregiver emotional distress symptoms compared with those who denied nonadherence. AYAs with MLVIs indicating nonadherence had more barriers than AYAs with MLVIs indicating adherence. Conclusions: Multimethod nonadherence evaluations for AYA transplant recipients should assess objective nonadherence using the MLVI, particularly in light of low reported nonadherence rates for antirejection medications. Assessments should include adherence barriers measures, given associations with the MLVI, and potentially prioritize assessing barriers over gauging nonadherence via self- or proxy-reports. Caregiver emotional distress symptoms may also be considered to provide insight into family or environmental barriers to adherence.

Fyn kinase regulates translation in mammalian mitochondria.

BACKGROUND: Mitochondrial translation machinery solely exists for the synthesis of 13 mitochondrially-encoded subunits of the oxidative phosphorylation (OXPHOS) complexes in mammals. Therefore, it plays a critical role in mitochondrial energy production. However, regulation of the mitochondrial translation machinery is still poorly understood. In comprehensive proteomics studies with normal and diseased tissues and cell lines, we and others have found the majority of mitochondrial ribosomal proteins (MRPs) to be phosphorylated. Neither the kinases for these phosphorylation events nor their specific roles in mitochondrial translation are known. METHODS: Mitochondrial kinases are responsible for phosphorylation of MRPs enriched from bovine mitoplasts by strong cation-exchange chromatography and identified by mass spectrometry-based proteomics analyses of kinase rich fractions. Phosphorylation of recombinant MRPs and 55S ribosomes was assessed by in vitro phosphorylation assays using the kinase-rich fractions. The effect of identified kinase on OXPHOS and mitochondrial translation was assessed by various cell biological and immunoblotting approaches. RESULTS: Here, we provide the first evidence for the association of Fyn kinase, a Src family kinase, with mitochondrial translation components and its involvement in phosphorylation of 55S ribosomal proteins in vitro. Modulation of Fyn expression in human cell lines has provided a link between mitochondrial translation and energy metabolism, which was evident by the changes in 13 mitochondrially encoded subunits of OXPHOS complexes. CONCLUSIONS AND GENERAL SIGNIFICANCE: Our findings suggest that Fyn kinase is part of a complex mechanism that regulates protein synthesis and OXPHOS possibly by tyrosine phosphorylation of translation components in mammalian mitochondria.

Evidence of Altered Mitochondrial Protein Expression After Chronic Ethanol Consumption in the Aged Estrogen-Deficient Female Rat Heart.

BACKGROUND: Estrogen loss has been implicated to increase the risk of alcoholic cardiomyopathy in postmenopausal women. The purpose of this study was to identify novel mitochondrial protein targets for the treatment of alcoholic cardiomyopathy in aged women using a state-of-the-art proteomic approach. We hypothesized that chronic ethanol (EtOH) ingestion exacerbates maladaptive mitochondrial protein expression in the aged female heart. METHODS: Adult (3 months) and aged (18 months) F344 ovary-intact or ovariectomized (OVX) rats were randomly assigned an EtOH or control Lieber-DeCarli "all-liquid" diet for 20 weeks. Proteomic analyses were conducted in mitochondria isolated from left ventricles using isobaric tags for relative and absolute quantification (iTRAQ) 8plex labeling and mass spectrometry (n = 3 to 5/group). RESULTS: After EtOH, significant differences (false discovery rate <5%) were observed in electron transport chain components (NADH dehydrogenase [ubiquinone] flavoprotein 2) as well as proteins involved in lipid metabolism (2,4 dienoyl-CoA reductase) and cellular defense (catalase), suggesting a possible link to congestive heart failure. Directional changes in protein levels were confirmed by Western blotting. Additionally, EtOH significantly reduced state 3 mitochondrial respiration in all groups, yet only reduced respiratory control index in the aged OVX rat heart (p < 0.05). CONCLUSIONS: Collectively, the data reveal that EtOH-induced changes in the mitochondrial proteome exacerbate cardiac dysfunction in aged and estrogen-deficient hearts, but not in adult. In conclusion, iTRAQ is a powerful tool for investigating new mitochondrial targets of alcoholic cardiomyopathy.

Family Functioning and Depressive Symptoms in Adolescent and Young Adult Cancer Survivors and Their Families: A Dyadic Analytic Approach.

Background: To examine dyadic relationships between depressive symptoms and family functioning in families of pediatric cancer survivors. Methods Sixty-four adolescent and young adult (AYA) cancer survivors and their caregivers self-reported on depressive symptoms and family functioning. Multilevel modeling analyses were used to test actor­partner interdependence models. Results: Significant actor effects of depressive symptoms on domains of family functioning were found for AYAs and their caregivers. Only caregivers' depressive symptoms exerted a significant effect on AYAs' report of family cohesion, indicating the presence of significant partner effects for AYAs. Conclusions: AYAs' and caregivers' depressive symptoms are related to poorer family functioning. Caregivers' perceptions of depressive symptoms relate not only to their own perceptions of family functioning but also to that of their children. These findings begin to map the complex relationships that exist between AYAs and their caregivers and elucidate some of the mechanisms through which caregiver-related variables affect AYA outcomes.

Pretransplant patient, parent, and family psychosocial functioning varies by organ type and patient age.

The goal of this study was to compare pretransplant patient HRQOL, parent psychological functioning, and the impact of the patient's ongoing illness on the family between organ types (ie, kidney, liver, heart) and age-groups (ie, children, AYAs). The sample included 80 pediatric patients with end-stage organ disease who were evaluated for transplantation and their parents. Parents completed self- and proxy reports at patients' pretransplant evaluations. Results indicated that patients evaluated for heart transplants consistently had lower HRQOL and their parents had greater psychological distress compared to the kidney and liver groups. Within the heart group, parents and families of children (<12 years old) experienced significantly more distress and impact of the patient's illness on the family compared to those of AYAs (≥12 years old). Pediatric patients awaiting heart transplants, particularly younger children, and their parents and families may have greater psychosocial needs compared to patients awaiting kidney or liver transplants.

Systematic and Meta-Analytic Review: Medication Adherence Among Pediatric Patients With Sickle Cell Disease.

OBJECTIVE: To provide a comprehensive summary (systematic review) of medication adherence rates by assessment method and medication type for pediatric patients with sickle cell disease (SCD), as well as identify important correlates for future research. METHODS: Articles assessing medication adherence and published between 1982 and February 2015 (n = 49) were identified using electronic databases. A meta-analysis of 14 studies examining demographic, medical, and psychosocial factors and medication adherence was conducted. RESULTS: Adherence rates ranged from 12% to 100% across all medications. Approximately 30% of studies reported associations between adherence and key demographic, medical, and psychosocial correlates. Mean effect sizes were small to moderate (r = .02-.53). CONCLUSIONS: The wide range of adherence rates reported in the literature may be because of, in part, the use of variable assessment strategies. Future studies examining pediatric SCD adherence should incorporate key correlates with the goal of replication.

Executive Functioning, Barriers to Adherence, and Nonadherence in Adolescent and Young Adult Transplant Recipients.

OBJECTIVE : To evaluate levels of executive functioning in a sample of adolescent and young adult (AYA) transplant recipients, and to examine executive functioning in association with barriers to adherence and medication nonadherence. METHOD : In all, 41 caregivers and 39 AYAs were administered self- and proxy-report measures. RESULTS : AYA transplant recipients have significant impairments in executive functioning abilities. Greater dysfunction in specific domains of executive functioning was significantly associated with more barriers to adherence and greater medication nonadherence. CONCLUSION : AYA transplant recipients are at increased risk for executive dysfunction. The assessment of executive functioning abilities may guide intervention efforts designed to decrease barriers to adherence and promote developmentally appropriate levels of treatment responsibility.

Intellectual and academic performance in children undergoing solid organ pretransplant evaluation.

Although prior research has shown lower intellectual functioning across pediatric solid organ transplant recipients relative to matched siblings or norm comparisons, few studies have assessed intellectual and academic performance prior to transplant across organ groups. The current data examine intellectual and academic functioning in children being evaluated for kidney, liver, or heart transplant. This investigation included intellectual and academic testing data from 195 children and adolescents between the ages of six and 19 yr evaluated for solid organ transplantation. Across organ groups, patients' intellectual functioning as estimated by the WASI/WASI-II at the time of pretransplant evaluation was within the average range, but lower compared to test norms. Patients demonstrated lower estimates of word reading, math computation, and spelling skills compared to the normal population, with the exception of heart patients' word reading and spelling skills and liver patients' spelling scores. Cognitive and academic impairments exist in children prior to transplantation. Findings emphasize the support that patients may require to manage the complicated medical regimen and succeed academically. Routine cognitive and academic assessment can inform healthcare providers regarding transplant patients' capacity to take on increasing medical responsibility and successfully reintegrate into the school environment.
