Meta AnalysisAttention deficit hyperactivity disorder and sleep disordered breathing in pediatric populations: a meta-analysis.
A relationship between attention deficit hyperactivity disorder (ADHD) and sleep disordered breathing (SDB) in children and adolescents has been suggested by some authors. Yet, this topic remains highly controversial in the literature. A meta-analysis was conducted in order to examine the extent of relationship between SDB and ADHD symptoms in pediatric populations and whether there are differences in ADHD symptoms pre- versus post-adenotonsillectomy in pediatric populations. ⋯ The findings of this meta-analysis suggest that ADHD symptoms are related to SDB and improve after adenotonsillectomy. Therefore, patients with ADHD symptomatology should receive SDB screening. Treatment of comorbid SDB should be considered before medicating the ADHD symptoms if present.

Meta Analysis Comparative StudyComparison of positional therapy versus continuous positive airway pressure in patients with positional obstructive sleep apnea: a meta-analysis of randomized trials.
Obstructive sleep apnea (OSA), caused by the obstruction of the upper airway, is the most common type of sleep apnea. Continuous positive airway pressure (CPAP) and positional therapy have been shown to be effective to improve positional OSA. ⋯ CPAP is superior to positional therapy in reducing the severity of sleep apnea and increasing the oxygen saturation level in patients with positional OSA.

Meta AnalysisInsomnia and daytime cognitive performance: a meta-analysis.
Individuals with insomnia consistently report difficulties pertaining to their cognitive functioning (e.g., memory, concentration). However, objective measurements of their performance on neuropsychological tests have produced inconsistent findings. This meta-analysis was conducted to provide a quantitative summary of evidence regarding the magnitude of differences between individuals with primary insomnia and normal sleepers on a broad range of neuropsychological measures. ⋯ Individuals with insomnia exhibit performance impairments for several cognitive functions, including working memory, episodic memory and some aspects of executive functioning. While the data suggests that these impairments are of small to moderate magnitude, further research using more ecologically valid measures and normative data are warranted to establish their clinical significance.
