The relationship between pain and sleep in pediatric sickle cell disease.

Background: Pain and sleep disturbances are prevalent complications experienced by pediatric patients with sickle cell disease (SCD). This study aims to identify associations between pain and sleep, and to characterize sleep chronotype and social jetlag in children and adolescent patients with SCD.

Methods: We performed a cross-sectional survey of 105 pediatric patients with SCD aged 8-17 years using PROMIS (Patient Reported Outcomes Measurement System) pain interference, sleep disturbance, and sleep-related impairment item banks.

The association between sleep disturbances and neurocognitive function in pediatric sickle cell disease.

Background And Objective: Youth with sickle cell disease (SCD) without neurological complications continue to be at increased risk of neurocognitive difficulties. Nocturnal hypoxemia is associated with neurocognitive outcomes and has been identified as a chronic complication in youth with SCD. The objective of this study was to assess the relationship between sleep disturbances and neurocognitive functioning in youth with SCD, while taking into account demographic and socioeconomic factors.

The Effects of Radiation and Sex Differences on Adaptive Functioning in Adult Survivors of Pediatric Posterior Fossa Brain Tumors.

Objective: Radiation therapy (RT) improves rates of survival of patients with childhood brain tumors but increases deficits in cognition and independent living skills. Previous literature has studied difficulties in basic cognitive processes, but few explore impairment in higher-order skills such as adaptive functioning. Some studies identify females as at risk for cognitive deficits due to RT, but few investigate sex differences in adaptive functioning.
