A recently discovered neurodevelopmental disorder caused by the mutation of the cyclin-dependent kinase-like 5 gene (CDKL5) entails complex autistic-like behaviours similar to Rett syndrome, but its impact upon physiological functions remains largely unexplored. Sleep-disordered breathing is common and potentially life-threatening in patients with Rett syndrome; however, evidence is limited in children with CDKL5 disorder, and is lacking altogether in adults. The aim of this study was to test whether the breathing pattern during sleep differs between adult Cdkl5 knockout (Cdkl5-KO) and wild-type (WT) mice...

Few data are available about the pattern of upper airway (UA) obstruction in children <2 years with obstructive sleep apnea syndrome (OSAS). Also, the role of adenoidectomy versus adenotonsillectomy (AT) is poorly defined in this age group. We performed drug-induced sedation endoscopy (DISE) in young OSAS children to investigate the pattern of UA obstruction and the value of DISE in therapeutic decision making. Retrospective analysis of ≤2-year-old children undergoing DISE-directed UA surgery. OSAS severity and the treatment outcomes were documented by polysomnography...

Sudden unexplained nocturnal death syndrome (SUNDS) remains an autopsy negative disorder with unclear etiology. Vinculin (VCL) was linked to sudden arrhythmia death in VCL knockout mice prior to the appearance of cardiomyopathy. We hypothesized VCL mutations underlie risk for SUNDS. A rare heterozygous variant VCL-M94I was found in a SUNDS victim who suffered sudden nocturnal tachypnea and lacked pathogenic variants in known arrhythmia-causing genes. VCL was identified to interact with SCN5A in vitro/vivo. The VCL-M94I was co-expressed with the cardiac sodium channel in HEK293 cells and also overexpressed in induced pluripotent stem cells derived cardiomyocytes (iPSCs-CM)...

OBJECTIVE: In obstructive sleep apnea syndrome (OSAS), any of the activated neural, vascular, hemodynamic, metabolic, inflammatory, and thrombotic mechanisms may be related to increased cerebrovascular disease and risk of death; however, the possible pathophysiological process between obstructive sleep apnea syndrome and stroke has not been clearly explained. We hypothesize that alterations in vasomotor reactivity in patients may be responsible for their altered cerebral blood flow, and may contribute to the increased risk of ischemic stroke...

INTRODUCTION: Little is known about the pediatric population at an increased risk of restless legs syndrome (RLS) and periodic limb movement disorder (PLMD). Polysomnographic data from the Caffeine for Apnea of Prematurity-Sleep (CAPS) study showed a high prevalence of elevated periodic limb movement index (PLMI) in a cohort of ex-preterm children, but the clinical importance of this finding, such as association with RLS, is unknown. We hypothesized that ex-preterm children would have a high prevalence of RLS and PLMD...

OBJECTIVE: Obstructive sleep apnea (OSA) is common among overweight and obese children, and it is an independent risk factor for developing metabolic syndrome. However, the mechanisms linking OSA and metabolic syndrome are still unclear, but a role for adipose tissue dysfunction caused by intermittent hypoxia has been suggested. Therefore, the goal of this study was to investigate the relationship between OSA and systemic adipokine concentrations in overweight and obese children. METHODS: We included 164 overweight and obese children in a tertiary center and distributed them in groups based on their obstructive apnea-hypopnea index (111 controls, 28 mild OSA, 25 moderate-to-severe OSA)...

BACKGROUND: Obstructive sleep apnea (OSA) and chronic obstructive pulmonary disease (COPD) are independent risk factors for cardiovascular diseases. In patients with OSA and concurrent COPD, continuous positive airway pressure (CPAP) therapy improves survival. Nevertheless, a significant proportion of such patients do not tolerate CPAP. The aim of the present study was to analyze early predictors of CPAP failure in patients with OSA and concurrent COPD, and to evaluate the effects of bilevel positive airway pressure (BiPAP) in this high-risk group of patients...

INTRODUCTION: To promote adaptation to treatment with continuous positive airway pressure, an information document was developed for people starting their treatment with continuous positive airway pressure. METHODS: Seven patients with obstructive sleep apnea took part in a focus group. This allowed the identification both of useful information and the best way that this information could be presented. RESULTS: The key specific information objectives and the best emotional register to use were as follows: (1) develop awareness about the physiological mechanisms and consequences that can occur from obstructive sleep apnea syndrome, using formulations arousing fear, (2) enable the recognition of the symptoms, risk factors and chronicity of this syndrome, (3) reassure and motivate the patient about treatment with continuous positive airway pressure...

Obstructive sleep apnea (OSA) leads to multiple end-organ morbidities that are mediated by the cumulative burden of oxidative stress and inflammation. Both OSA and inflammation play key roles in increased risk of cardiovascular disease (CVD). Thus, we hypothesized that the combination of inflammation and OSA could accelerate the development of metabolic syndrome (MetS) in a large cohort study.A total of 1835 participants were randomly selected from the ongoing Korean Genome and Epidemiology Study for the years between 2007 and 2015...

BACKGROUND: Obstructive sleep apnea (OSA) is a public health problem. Detailed analysis of the para-pharyngeal fat pads can help us to understand the pathogenesis of OSA and may mediate the intervention of this sleeping disorder. A reliable and automatic para-pharyngeal fat pads segmentation technique plays a vital role in investigating larger data bases to identify the anatomic risk factors for the OSA. METHODS: Our research aims to develop a context-based automatic segmentation algorithm to delineate the fat pads from magnetic resonance images in a population-based study...

Attention-deficit/hyperactivity disorder (ADHD) is frequently accompanied with sleep disorders such as obstructive sleep apnea, periodic limb movement disorder, restless legs syndrome (RLS), and circadian rhythm disorder. We have limited information about the effects of medical therapies used in the treatment of ADHD on RLS. This article discusses the effects of atomoxetine treatment on both disorders in a patient followed by diagnoses of ADHD and RLS.

Patau syndrome remains a difficult diagnosis for parents and a challenging conversation for clinicians due to the overall poor prognosis. Previous population-based reports have documented the sobering life expectancies of these patients, with few surviving to 1 year of age. Despite the high mortality rate in infants born with trisomy 13, there are several reports of survival into late childhood and early adulthood. While clinical outcomes have been well documented, there has been a paucity of literature describing postnatal imaging findings in long-term survivors...
