ABSTRACT
BACKGROUND: Legacy-oriented interventions have the potential to offer pediatric oncology patients and families comfort at end of life and during bereavement. Certified child life specialists often provide these services, and presently little is known about whether disparities exist in the provision of legacy-oriented interventions. METHODS: In this retrospective decedent cohort study, we examined demographic and clinical characteristics from a sample of 678 pediatric oncology patients who died between 2015 and 2019. Bivariate analysis assessed differences between patients who received any versus no legacy-oriented intervention. Uni- and multivariable logistic regression models assessed associations of baseline characteristics and likelihood of receiving legacy-oriented intervention. Further multivariable analysis explored joint effects of significant variables identified in the univariable analysis. RESULTS: Fifty-two percent of patients received a legacy-oriented intervention. Older adolescents (≥13 years) were less likely (odds ratio [OR]: 1.73, p = .007) to receive legacy-oriented interventions than younger ones. Patients with home/hospice deaths were also less likely (OR: 19.98, p < .001) to receive interventions compared to patients who passed away at SJCRH locations. Hispanic patients (OR: 1.53, p = .038) and those in palliative care (OR: 10.51, p < .001) were more likely to receive interventions. No significant race association was noted. CONCLUSION: All children and adolescents with cancer deserve quality care at end of life, including access to legacy-oriented interventions, yet nearly half of patients in this cohort did not receive these services. By identifying demographic and clinical characteristics associated with decreased odds of receiving legacy-oriented interventions, healthcare professionals can modify end-of-life care processes to improve access. Introducing legacy-oriented interventions early and increasing exposure in community spaces may enhance access to legacy-oriented interventions for pediatric oncology patients.

Dextrocardia, a rare congenital heart condition, can occur in about 1 out of every 12,000 pregnancies. Dextrocardia with situs solitus refers to when the heart is on the right side of the thorax while other viscera are found in their normal positions. The condition can go unnoticed in cases of limited prenatal care and newborn evaluation, leading to patients never receiving pertinent cardiac evaluations and condition progression monitoring throughout their lives. This is the first case reported of isolated dextrocardia with situs solitus in a neonate without any additional cardiovascular abnormalities. This case report highlights the importance of prenatal and postnatal evaluation to ensure the identification of neonates with dextrocardia and improve their quality of life and outcomes.
ABSTRACT
The paracrine interaction between tumor cells and adjacent stroma has been associated with the oncogenic activity of the Hedgehog (Hh) pathway in triple-negative breast tumors. The present study developed a model of paracrine Hh signaling and examined the impact of mesenchymal cell sources and culture modalities in the oncogenicity of the Hh pathway in breast tumor cells. Studies consisted of tumor cell monocultures and co-cultures with cancer-associated and normal fibroblasts, tumor cells that undergo epithelial-mesenchymal transition (EMT), or adipose-derived mesenchymal stem cells (ADMSCs). Hh ligand and pathway inhibitors, GANT61 and NVP-LDE225 (NVP), were evaluated in both cell cultures and a mouse xenograft model. Results in monocultures show that tumor cell viability and Hh transcriptional activity were not affected by Hh inhibitors. In co-cultures, down-regulation of GLI1, SMO, and PTCH1 in the stroma correlated with reduced tumor growth rates in xenografted tumors and cell cultures, confirming a paracrine interaction. Fibroblasts and EMT cells supported Hh transcriptional activity and enhanced tumor cell growth. Mixed and adjacent culture modalities indicate that tumor growth is supported via fibroblast-secreted soluble factors, whereas enriched tumor stemness requires close proximity between tumor and fibroblasts. Overall this study provides a tumor-mesenchymal model of Hh signaling and highlights the therapeutic value of mesenchymal cells in the oncogenic activity of the Hh pathway.
