    Description

    A bi‐directional relationship exists between asthma and obstructive sleep apnea (OSA) in which presence of one is associated with increased prevalence and severity of the other. This study was undertaken to determine if OSA accounted for differences in airway and systemic inflammation in asthmatic children and if inflammation was associated with asthma control. 27 non-obese children aged 4-12 years with persistent asthma, with or without OSA, were recruited for the research. Asthma control was measured with the Childhood Asthma Control Test. Participants underwent polysomnography and blood sampling, and those with OSA also underwent clinically indicated adenotonsillectomy. Tonsils and sera were analyzed for 11 cytokines. The dataset includes demographic data, health history, spirometry/polysomnographic measures, and immunoassay values.

    Description

    This 2-phase study explored the differences in sleep and circadian activity rhythms between adolescents who were within 5 years of completing treatment for any type of cancer and healthy, age-matched controls; and trialed a morning bright light therapy intervention to gather preliminary evidence of its safety, feasibility and outcomes.

    Description

    Periodic limb movements in sleep (PLMS) are associated with sleep fragmentation and sympathetic nervous system activation, which in turn have been linked to cognitive and behavioral deficits in children and cardiovascular morbidity in both adults and children. Emerging evidence indicates that many children with sickle cell disease (SCD) have elevated PLMS. The specific aims of this prospective, repeated-measures, descriptive study were to assess the agreement between PLMS measurement by actigraphy and concurrent polysomnography (PSG), to test the feasibility of measuring PLMS by actigraphy at home, to evaluate PLMS variability over consecutive nights by actigraphy, and to provide preliminary data on objective and subjective correlates of PLMS. Twenty children with SCD and restless legs syndrome (RLS) symptoms or polysomnography-documented PLMS underwent concurrent attended polysomnography and ankle activity monitoring over one to two nights and home activity monitoring for three nights. Serum iron and ferritin were measured pre- and post-polysomnography. The datasets associated with this study include demographic data, SCD subtype, polysomnographic/activity monitor values, medical history, and clinical measures.

    Description

    This study tested a sleep promotion intervention (randomized controlled trial) in children with recently diagnosed central nervous system tumors admitted to the hospital for high dose chemotherapy in preparation for autologous stem cell rescue. We hypothesized that disturbed sleep of hospitalized pediatric oncology patients would be reduced by altering the hospital sleep environment. Therefore, a randomized, attention-controlled sleep intervention was implemented in children and adolescents with central nervous system tumors admitted for 6 days for high dose chemotherapy prior to stem cell transplant. Children and adolescents diagnosed with medulloblastoma or histologically similar tumor, 4 to 19 years and their parent were recruited over 3 years.Questionnaires used to gather the data were: Fatigue Scale-Child, Fatigue Scale-Adolescent, Fatigue Scale-Parent. Data was also obtained using actigraphy.

    Description

    This was a retrospective medical record review of 55 consecutive children aged 2-18 years with sickle cell disease (SCD) (hemoglobin [Hb] SS and Hb SC genotypes) undergoing polysomnography for evaluation of sleep disordered breathing. Polysomnography values were compared between SCD genotypes, 4 age groups, and adenotonsillectomy status using descriptive and nonparametric statistics. Medical record data were collected for 12 months pre-polysomnography and 12 months post-polysomnography/adenotonsillectomy. This dataset includes demographic data, SCD type, polysomnographic values, and clinical measures.

    Description

    Children with sickle cell disease (SCD) experience neurodevelopmental decline over time. They also tend to have short duration, poor quality sleep and elevated fatigue levels. This study measured sleep via actigraphy over one week and cognitive and behavioral measures in 19 children and adolescents with SCD. Aged 7-18 years, the majority of participants were referred for neurodevelopmental testing due to academic or behavioral difficulties. Data was collected from parent report, medical record, and included age, sex, race, SCD genotype, results of neuroimaging studies including brain magnetic resonance imaging (MRI) and transcranial Doppler (TCD) velocities, and current use of hydroxyl urea or chronic blood transfusion. Additionally, parents completed the Behavior Rating Inventory of Executive Function (BRIEF), participants completed the Wide Range Achievement Test (WRAT), and both completed the PedsQL Multidimensional Fatigue Scale.
