Relationships between symptoms of hypersomnolence, psychiatric disorders, and hypersomnia disorders (i.e., narcolepsy and idiopathic hypersomnia) are complex and multidirectional. Hypersomnolence is a common complaint across mood disorders; however, patients suffering from mood disorders and hypersomnolence rarely have objective daytime sleepiness, as assessed by the current gold standard test, the Multiple Sleep Latency Test. An iatrogenic origin of symptoms of hypersomnolence, and sleep apnea syndrome must be considered in a population of psychiatric patients, often overweight and treated with sedative drugs...

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...

Heart failure (HF) is a complex syndrome with inherent diagnostic challenges. We studied the scope of possibly inaccurately documented HF in a large health care system among patients assigned a primary diagnosis of HF at discharge. Through a retrospective record review and a classification schema developed from published guidelines, we assessed the probability of the documented HF diagnosis being accurate and determined factors associated with HF-related and non-HF-related hospital readmissions. An arbitration committee of 3 experts reviewed a subset of records to corroborate the results...

Obstructive sleep apnoea syndrome (OSAS) is characterized by recurrent partial or complete pharyngeal collapses during sleep. The pathophysiology of OSAS is complex and multifactorial. Factors influencing upper airway patency include a reduction in upper airway dimensions that can result from both anatomical and functional alterations (obesity, fluid shift or maxillo-facial structural changes), and increased pharyngeal collapsibility owing to reduced neuromuscular compensation and lack of the pharyngeal protective reflex during sleep...

Nasal obstruction mainly caused by adenoid hypertrophy in children affects the craniofacial growth and development process, and the craniofacial deviations and/or differences reported in the children are very similar to those in the adults with obstructive sleep apnea syndrome (OSAS). The authors aimed to look for relationships of the linear craniofacial dimensions in the children suffering from nasal obstruction with age, degree of clinical nasal obstruction score (CNOS), and relative size of the adenoid mass within the nasopharynx in their study...

Although adenotonsillectomy is the first line treatment for children with obstructive sleep apnea syndrome (0SAS),(1) improvement in objectively documented outcomes is often inadequate and a substantial number of children have residual disease. Early recognition and treatment of children with persistent OSAS is required to prevent long-term morbidity. The management of these children is frequently complex and a multidisciplinary approach is required as most of them have additional risk factors for OSAS and comorbidities...

Obstructive sleep-disordered breathing (SDB) can result in cardiovascular and neurocognitive morbidity as well as adversely affect behavior, growth, quality of life, and nocturnal continence. This article summarizes the latest evidence regarding the morbidity related to obstructive SDB, commenting on the impact of severity of obstruction, that is, the difference in effects seen of moderate to severe obstructive sleep apnea syndrome (OSAS) compared to those of mild OSAS or primary snoring. The impact of therapy is discussed, focusing on which children are likely to benefit from treatment interventions; namely those with moderate or severe OSAS irrespective of the presence of morbidity, children with mild OSAS with associated morbidity or predictors of SDB persistence such as obesity, and children with complex conditions accompanied by upper airway obstruction like craniosynostosis and Prader-Willi syndrome...

The classical definition of Chronic Obstructive Pulmonary Disease (COPD) as a lung condition characterized by irreversible airway obstruction is outdated. The systemic involvement in patients with COPD, as well as the interactions between COPD and its comorbidities, justify the description of chronic systemic inflammatory syndrome. The pathogenesis of COPD is closely linked with aging, as well as with cardiovascular, endocrine, musculoskeletal, renal, and gastrointestinal pathologies, decreasing the quality of life of patients with COPD and, furthermore, complicating the management of the disease...

Anatomical basis of obstructive sleep apnea (OSA) is the collapse of the pharynx during sleep. It is considered as a result of complex interactions of structural and neuromuscular factors. Depth of sleep and body position have modulating effects. Although different areas of obstruction were identified, studies show that the sleep-mediated obstruction frequently occurs in the base of tongue area.Continuous positive airway pressure (CPAP) is the standard treatment for obstructive sleep apnea syndrome (OSAS) since more than 30 years...

Pediatric obstructive sleep apnea syndrome (OSAS) has a multifactorial origin. For the child with no dysmorphic disorders or comorbidities, its main etiology is pharyngeal soft tissue hypertrophy, a dimensional reduction of the facial skeletal frame restricting the airway, an anomaly of muscular tone, or a combination of these factors. Consequently, proper diagnosis and treatment planning for these children can require several medical specialties, according to the complexity, severity, and persistence of OSAS: ear-nose-throat specialists (ENT), pneumologists/allergologists, dentofacial orthopedists/orthodontists, and physical therapists/speech therapists...

Obesity, along with hypertrophy of the adenoids and the tonsils, represents one of the major risk factors for obstructive sleep apnea (OSA) in children. Obesity is associated with an increase in the prevalence and the severity of OSA and is a major factor in the persistence and aggravation of OSA over time. Neurocognitive dysfunction and abnormal behavior are the most important and frequent end-organ morbidities associated with OSA in children. Other deleterious consequences such as cardiovascular stress and metabolic syndrome are less common in children than in adults with OSA...

Obstructive sleep apnea-hypopnea syndrome (OSAHS) is a complex chronic inflammatory respiratory disease with multiple pathogenic factors and high morbidity and mortality. Serum levels of nuclear factor-κB (NF-κB), hypoxia-inducible factor-1 alpha (HIF-1α), and surfactant protein D (SPD) were investigated in OSAHS patients, to determine their clinical significance and correlation with the pathogenesis. Patients were classified into a mild and moderate OSAHS group (n = 25) and severe OSAHS group (n = 33). Twenty healthy patients served as a control group...

Obstructive sleep apnea syndrome (OSAS) is the most common type of sleep disorder which is associated with a series of cardiovascular disorders, including right ventricular (RV) dysfunction. However, it is difficult to assess the RV function systematically using a conventional echocardiography because RV has a complex geometrical shape. A case-control study was performed to assess the regional right ventricular potential dysfunction in patients with OSAS using velocity vector imaging (VVI) from March 2014 to October 2015...

OBJECTIVE: This study aimed to determine association obstructive sleep apnea (OSA) with increased coagulability and reveal possible effects of constant positive airway pressure (CPAP). DESIGN AND METHOD: We included 77 patients with arterial hypertension (duration of AH = 13.8 ± 3.7 years), middle-aged (45.9 ± 10.5 years). 41 (53.2%) of them had severe OSA (AHI = 59.6 ± 26). OSA was diagnosed by means of cardiorespiratory monitoring. In patients with severe OSA blood samples (D-dimer, viscosity of blood, erythrocyte aggregation) were taken at baseline and after 3-4 nights of effective CPAP therapy (AHI < 5)...

Zolpidem-induced sleep-related complex behaviors (SRCB) with anterograde amnesia have been reported. We describe herein a case in which the development of zolpidem-induced sleep-related eating disorder (SRED) and SRCB was strongly suspected. A 71-year-old Korean male was admitted to the Department of Psychiatry due to his repetitive SRED and SRCB with anterograde amnesia, which he reported as having occurred since taking zolpidem. The patient also had restless legs syndrome (RLS) and obstructive sleep apnea (OSA)...

Endothelin-1, (ET-1, EDN1) is endogenous polypeptide demonstrates dominant vasoconstriction activity and mitogenic effect, on the heart it has positive inotropic and chronotropic properties, stimulates the sympathetic and the renin-angiotensin-aldosterone systems and modify homeostasis. The human ET-1 gene which consists of 6836 nucleotides located on chromosome 6p23-p24 produces Pre-pro-ET-1, which consequently cleaved to big-ET-1. The mature 21-amino acid ET-1 is generated by subsequent enzymatic cleavage of the big-ET-1...

BACKGROUND: Physical activity programs are a powerful tool against several diseases including obesity and their comorbidities. Prader-Willi syndrome is the most common genetic disease associated with obesity, and brings with it behavioral and emotional problems that need complex management. Research into the effect of physical activity programs on Prader-Willi syndrome is limited and it is frequently argued that if a physical activity program is too complex, the participants are more likely to drop out...
