Multicenter Study Clinical TrialHealth literacy variables related to parents' understanding of their child's cancer prognosis.
Obtaining an accurate understanding of a child's cancer prognosis can help parents make informed decisions about treatment. Research has shown that parents tend to overestimate their child's cancer prognosis relative to physicians. Thus, we examined whether the content of physician communication, parent sources of medical information, and parent demographic factors affected the association between oncologist and parent estimates of a child's cancer prognosis. ⋯ Fathers' age may be important to their understanding of their child's cancer prognosis, but we did not find support for other factors related to prognosis literacy. Given the homogeneity of our sample, future research should assess differences in parents' prognosis knowledge across cancer diagnosis, race, ethnicity, and socioeconomic status (SES), which may aid in developing interventions to improve parent understanding.

Clinical TrialCerebral tissue hemoglobin saturation in children with sickle cell disease.
Desaturation of hemoglobin (Hb) in cerebral tissue, a physiologic marker of brain vulnerable to ischemic injury, can be detected non-invasively by transcranial oximetry. Absolute cerebral oximetry has not been studied in sickle cell disease (SCD), a group at very high risk of cerebral infarction in whom prevention of brain injury is key. ⋯ Cerebral desaturation, a physiologic marker of at-risk brain, is common in SCD, more severe in HbSS/Sβ(0) patients, and associated with peripheral desaturation, more severe anemia, and increasing age. Cerebral oximetry has the potential to improve the identification of children with SCD at highest risk of neurologic injury and possibly serve as a physiologic guide for neuroprotective therapy.
