Racial and Ethnic Differences in Inpatient Palliative Care for Pediatric Stem Cell Transplant Patients.

Objectives: Racial/ethnic disparities in utilizing inpatient palliative care services are well documented in the adult literature. However, the impact of racial/ethnic disparities in the context of pediatric palliative care is less well understood even in high-acuity patient populations such as stem cell transplant patients. We investigated racial/ethnic differences in the utilization of inpatient palliative care consultations (IPCCs) for pediatric stem cell transplant patients.

Osteitis fibrosa is mediated by Platelet-Derived Growth Factor-A via a phosphoinositide 3-kinase-dependent signaling pathway in a rat model for chronic hyperparathyroidism.

Abnormal secretion of PTH by the parathyroid glands contributes to a variety of common skeletal disorders. Prior studies implicate platelet-derived growth factor-A (PDGF-A) as an important mediator of selective PTH actions on bone. The present studies used targeted gene profiling and small-molecule antagonists directed against candidate gene products to elucidate the roles of specific PTH-regulated genes and signaling pathways.
