Sleep-disordered breathing in children is most prevalent in the pre-school years and has been associated with sleep fragmentation and hypoxia. We aimed to compare the sleep and spontaneous arousal characteristics of 3-5-year-old children with obstructive sleep apnoea (OSA) with that of non-snoring control children, and to further characterise the arousal responses to obstructive respiratory events. ⋯ These findings suggest that in pre-school children OSA has a profound effect on sleep and arousal patterns. Given that these children are at a critical period for brain development, the impact of OSA may have more severe consequences than in older children.

Randomized Controlled Trial Multicenter Study
Clinical efficacy and safety of IV ferric carboxymaltose (FCM) treatment of RLS: a multi-centred, placebo-controlled preliminary clinical trial.
Intravenous (IV) iron has been used as a treatment to reduce Restless Legs Syndrome (RLS) symptoms, but two double-blinded trials of a frequently prescribed IV iron formulation, iron sucrose, failed to show lasting efficacy. This study evaluates efficacy and safety of a new IV iron formulation (ferric carboxymaltose, FCM) with molecular properties that may make iron more available for uptake to the brain than iron sucrose does. ⋯ IV FCM provided a safe and effective treatment for RLS that lasted for at least 24 weeks for some patients. Larger studies are needed to confirm these results.

Randomized Controlled Trial
Managing sleep problems in school aged children with ADHD: a pilot randomised controlled trial.
To evaluate the feasibility and helpfulness of a behavioral sleep program for children with ADHD, and explore the impact of different program dosages on child and family outcomes. ⋯ A behavioral sleep intervention in children with ADHD is feasible to deliver and improves child sleep by parent report. The extended program resulted in greater improvements in child and caregiver outcomes.

There is limited data on chronic insomnia in Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) veterans, in whom post-traumatic stress disorder (PTSD) and mild traumatic brain injury (mTBI) often co-exist. Our aim was to compare sleep characteristics of three groups of OEF/OIF veterans: (1) healthy sleepers (HS), (2) those with insomnia associated with PTSD and mTBI (PTSD-mTBI), and (3) those with insomnia associated with PTSD alone. ⋯ Insomnia patients with PTSD-mTBI were subjectively sleepier despite spending less time awake during the night than PTSD subjects, possibly as a consequence of head trauma.

The clinical significance of rapid eye-movement (REM)-related obstructive sleep apnea (OSA) is unknown. Moreover, it is unclear what the determinants of sleepiness and quality of life (QoL) are among these patients. Our aim was to identify whether the apnea-hypopnea index during REM sleep (AHI(REM)), AHI during NREM sleep (AHI(NREM)), depressive symptoms, or obesity are independent predictors of excessive daytime sleepiness and reduced QoL in patients with REM-related OSA. We also assessed if these characteristics were predictors of sleepiness and QoL in all patients with OSA (AHI ≥ 5) as well as in non-stage specific OSA. ⋯ Higher depression scores and obesity, rather than the severity of OSA (as measured by AHI(NREM) and AHI(REM)), were predictive of sleepiness and QoL scores in patients with REM-related OSA.
