RESUMEN
The use of hematopoietic cell transplantation (HCT) for treating malignant conditions in children has increased over the past five decades, leading to a growing population of long-term survivors.This population of childhood HCT survivors faces increased risks of adverse medical effects due to cancer treatments, including adverse cardiovascular disease (CVD) risk factors such as metabolic syndrome, insulin resistance. but the impact of exposure to HCT preparative conditioning regimen has not been clearly delineated. These risk factors, including obesity, dyslipidemia, hypertension, and insulin resistance (IR), are significant contributors to premature cardiovascular disease and represent a leading cause of non-relapse deaths in childhood cancer and HCT survivors. This study aimed to assess the early development of CVD risk factors and their relationship to insulin resistance in a large population of pediatric and young adult HCT survivors of childhood hematologic malignancies. The study compared their cardiovascular risk profiles, insulin resistance (measured by euglycemic hyperinsulinemic clamp studies), and body composition (determined by dual X-ray absorptiometry - DXA) with a cohort of sibling controls. We enrolled 151 HCT recipients (26.36 ±0.90 years at study enrollment; time since HCT of 2.6-31.5 years) and 92 sibling controls to complete at cardiovascular risk assessment including insulin sensitivity by hyperinsulinemic euglycemic clamp, anthropometry, body composition by dual X-ray absorptiometry, blood pressure, and serum biomarkers. We used linear models to test for mean differences in all continuous outcomes between survivors and siblings, accounting for intra-family correlations with generalized estimating equations. Recipients of HCT were found to have lower insulin sensitivity and more likely to have adverse CVD risk factors in comparison to their healthy siblings. Significantly higher percent fat mass and visceral adipose tissue, and significantly lower lean body mass were noted in HCT recipients than sibling controls despite having a similar body mass index between the two groups. Total body irradiation in the conditioning regimen was one of the strongest factors associated with lower insulin sensitivity, dyslipidemia and abnormal body composition leading to sarcopenic obesity. This study reveals that pediatric and young adult HCT survivors are more insulin resistant and have a higher prevalence of adverse cardiovascular risk factors compared to sibling controls. The presence of cardiovascular risk factors at a relatively young age raises concerns about an escalating trajectory of cardiovascular disease in this population. Therefore, regular monitoring of HCT survivors for cardiometabolic risk factors and early intervention will be crucial for preventing cardiovascular-related complications in the future. The findings underscore the importance of survivorship care for pediatric and young adult HCT survivors, with a focus on managing cardiovascular risk factors and promoting a healthy lifestyle to mitigate long-term adverse effects. Early identification and targeted interventions can significantly improve the long-term health outcomes of this vulnerable population, reducing the burden of cardiovascular disease and related complications.

BACKGROUND: Adolescent hematopoietic cell transplant (HCT) recipients remain out of school for a prolonged period of time; navigating their return to school after completion of therapy can be challenging for caregivers. METHODS: Between August 2020 and June 2021, we conducted individual semi-structured interviews of 19 caregivers of adolescent HCT recipients (10-18 years of age at HCT; 1-7 years post HCT) to understand the challenges faced at the time of their child's return to in-person school post HCT. Conventional content analysis was used to analyze interview transcripts, and thematic analysis was used to identify and organize emerging themes. RESULTS: Three themes emerged from the caregivers' experiences. First, caregivers reported facing several challenges related to lack of communication between their child's healthcare and school teams, which was burdensome for them. Second, some caregivers reported receiving support from school and healthcare professionals, as well as their child's peers, which helped reduce the burden of return to school. Caregivers also reported providing motivational, emotional, and spiritual support to patients. Lastly, caregivers made several recommendations regarding the need for better communication between family, healthcare professionals, and school professionals and availability of supportive care such as mental health counseling and neuropsychological testing. Notably, the need for a return-to-school navigator emerged as a key finding from our analysis. CONCLUSIONS: Caregivers of adolescent HCT recipients face several challenges supporting their children's return to school post HCT, which are related to lack of communication between patients' healthcare and school teams. While some reported receiving support from school and healthcare professionals and their child's peers, the need to coordinate the return-to-school process was burdensome for several caregivers. Additional work is needed to optimize support for HCT recipients and their caregivers during their return-to-school process to minimize burden. Our study findings have the potential to serve as a framework for developing and testing supportive care interventions to improve the return-to-school experience of HCT survivors and ultimately their quality of life.
RESUMEN
BACKGROUND: Adolescent and young adult (AYA) hematopoietic cell transplantation (HCT) survivors are at increased risk of metabolic syndrome and lean body mass (LBM) deficits. Resistance training (RT) is a potential intervention to improve LBM, metabolic fitness, and reduce risk of cardiovascular disease. PROCEDURE: Eligible participants ages 13-39 years, 80-120 days post-HCT, transfusion independent, and prednisone dose ≤1 mg/kg/day were approached. Baseline assessments of body composition (DXA), anthropometrics, and strength testing were completed and participants were taught a 12-week, home-based RT intervention with weekly remote coaching. Follow-up assessments were at day +200 (FU1) and +365 post-HCT (FU2). Feasibility targets were (a) 60% enrollment of approached patients, (b) 80% completion of weekly phone calls, and (c) 80% completion of the RT intervention and FU1 assessments. Acceptability was based on positive responses in qualitative interviews. RESULTS: Twenty of 31 (65%) eligible AYAs enrolled. Three participants failed to complete baseline measurements (2 = scheduling barriers, 1 = passive refusal) and four participants who completed baseline assessments did not receive the intervention (1 = medical reasons, 2 = no longer interested). Of those who completed baseline assessments, 13 received the intervention, completed 88.5% of coaching calls, and 11 (65%) completed FU1. LBM (kg) increased or remained unchanged in nine of nine participants with complete body composition data at FU1 (mean 1.1 kg; 95%CI: 0.4, 1.9). All participants who completed FU1 reported they would recommend the intervention to an AYA HCT survivor. CONCLUSIONS: A home-based RT intervention in AYA HCT survivors early post HCT is both feasible and acceptable and may maintain or increase LBM.

OBJECTIVE: To determine whether a brief intervention for children with functional abdominal pain and their parents' responses to their child's pain resulted in improved coping 12 months later. DESIGN: Prospective, randomized, longitudinal study. SETTING: Families were recruited during a 4-year period in Seattle, Washington, and Morristown, New Jersey. PARTICIPANTS: Two hundred children with persistent functional abdominal pain and their parents. INTERVENTIONS: A 3-session social learning and cognitive behavioral therapy intervention or an education and support intervention. MAIN OUTCOME MEASURES: Child symptoms and pain-coping responses were monitored using standard instruments, as was parental response to child pain behavior. Data were collected at baseline and after treatment (1 week and 3, 6, and 12 months after treatment). This article reports the 12-month data. RESULTS: Relative to children in the education and support group, children in the social learning and cognitive behavioral therapy group reported greater baseline to 12-month follow-up decreases in gastrointestinal symptom severity (estimated mean difference, -0.36; 95% CI, -0.63 to -0.01) and greater improvements in pain-coping responses (estimated mean difference, 0.61; 95% CI, 0.26 to 1.02). Relative to parents in the education and support group, parents in the social learning and cognitive behavioral therapy group reported greater baseline to 12-month decreases in solicitous responses to their child's symptoms (estimated mean difference, -0.22; 95% CI, -0.42 to -0.03) and greater decreases in maladaptive beliefs regarding their child's pain (estimated mean difference, -0.36; 95% CI, -0.59 to -0.13). CONCLUSIONS: Results suggest long-term efficacy of a brief intervention to reduce parental solicitousness and increase coping skills. This strategy may be a viable alternative for children with functional abdominal pain. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT00494260.

OBJECTIVES: Unexplained abdominal pain in children has been shown to be related to parental responses to symptoms. This randomized controlled trial tested the efficacy of an intervention designed to improve outcomes in idiopathic childhood abdominal pain by altering parental responses to pain and children's ways of coping and thinking about their symptoms. METHODS: Two hundred children with persistent functional abdominal pain and their parents were randomly assigned to one of two conditions-a three-session intervention of cognitive-behavioral treatment targeting parents' responses to their children's pain complaints and children's coping responses, or a three-session educational intervention that controlled for time and attention. Parents and children were assessed at pretreatment, and 1 week, 3 months, and 6 months post-treatment. Outcome measures were child and parent reports of child pain levels, function, and adjustment. Process measures included parental protective responses to children's symptom reports and child coping methods. RESULTS: Children in the cognitive-behavioral condition showed greater baseline to follow-up decreases in pain and gastrointestinal symptom severity (as reported by parents) than children in the comparison condition (time x treatment interaction, P<0.01). Also, parents in the cognitive-behavioral condition reported greater decreases in solicitous responses to their child's symptoms compared with parents in the comparison condition (time x treatment interaction, P<0.0001). CONCLUSIONS: An intervention aimed at reducing protective parental responses and increasing child coping skills is effective in reducing children's pain and symptom levels compared with an educational control condition.
