HU-treated patients experienced statistically significant decreases in TCDi velocities compared to age-matched controls. Changes in hematologic parameters were not predictive of changes in TCDi velocities in the treated group. The decrease in TCDi velocities is not a consequence of changes in hematologic values in patients treated with HU.
Children with sickle cell disease (SCD) have high risk of neurologic morbidity and mortality, such as strokes, silent infarcts and TIA's. A retrospective review of magnetic resonance imaging and magnetic resonance angiography identified eight children with radiological and clinical characteristics of reversible posterior encephalopathy (RPLS). These patients had no evidence of previous cerebral infarcts or vasculopathy. Three have died during the 5-year follow up; one developed a stroke and one a conditional TCD. RPLS needs to be considered in the differential diagnosis of children with SCD that present with acute neurological changes, especially if they are already been hospitalized.
Pre-implantation genetic diagnosis (PGD) is an option for parents who have a child with sickle cell disease (SCD) to have another child without SCD. We conducted a survey of 19 parents with at least one child with SCD to investigate views on PGD. Before education, 44% of parents were aware of PGD. All parents rated PGD education as important. All parents considering another child also reported interest in using PGD if insurance covered its costs. Parents who have a child with SCD appear to be interested in PGD and educational tools informing this group about PGD should be developed.
Children with SCD are at risk for developing multiple intracranial aneurysms, and a high index of suspicion must be maintained during the interpretation of routine magnetic resonance imaging or angiography of the brain.
Background: Transition to adult healthcare is a critical time for adolescents and young adults (AYAs) with sickle cell disease, and preparation for transition is important to reducing morbidity and mortality risks associated with transition.Objective: We explored the relationships between decision-making involvement, self-efficacy, healthcare responsibility, and overall transition readiness in AYAs with sickle cell disease prior to transition.Methods: This cross-sectional, correlational study was conducted with 50 family caregivers-AYAs dyads receiving care from a large comprehensive sickle cell clinic between October 2019 and February 2020. Participants completed the Decision-Making Involvement Scale, the Sickle Cell Self-Efficacy Scale, and the Readiness to Transition Questionnaire. Multiple linear regression was used to assess the relationships between decision-making involvement, self-efficacy, healthcare responsibility, and overall transition readiness in AYAs with sickle cell disease prior to transition to adult healthcare.Results: Whereas higher levels of expressive behaviors, such as sharing opinions and ideas in decision-making, were associated with higher levels of AYA healthcare responsibility, those behaviors were inversely associated with feelings of overall transition readiness. Self-efficacy was positively associated with overall transition readiness but inversely related to AYA healthcare responsibility. Parent involvement was negatively associated with AYA healthcare responsibility and overall transition readiness.Discussion: While increasing AYAs' decision-making involvement may improve AYAs' healthcare responsibility, it may not reduce barriers of feeling unprepared for the transition to adult healthcare. Facilitating active AYA involvement in decisionmaking regarding disease management, increasing self-efficacy, and safely reducing parent involvement may positively influence their confidence and capacity for self-management.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
