Background Oral appliance therapy for obstructive sleep apnea can be helpful in mild and moderate cases. This clinical report evaluates the efficacy of a protocol that predicts an optimal jaw position and describes the response of a young OSA patient to treatment. Clinical Presentation A 27-year-old woman was diagnosed with moderate OSA and had an apnea-hypopnea index (AHI) of 25.8/hr. In order to fabricate a custom device, an alternative procedure to determine the optimal protrusion and vertical positioning of the jaw was applied...

The retrotrapezoid nucleus (RTN) is one of several CNS nuclei that contribute, in various capacities (e.g. CO2 detection, neuronal modulation) to the central respiratory chemoreflex (CRC). Here we test how important the RTN is to PCO2 homeostasis and breathing during sleep or wake. RTN Nmb positive neurons were killed with targeted microinjections of substance-P-saporin conjugate in adult rats. Under normoxia, rats with large RTN lesions (92 ± 4 % cell loss) had normal blood pressure (BP) and arterial pH but were hypoxic (-8 mmHg PaO2 ) and hypercapnic (+10 mmHg PaCO2 )...

Background: Sleep disturbance is one of the major non-motor symptoms which cause the disability of Parkinson's disease (PD) patients. Cystatin C (CysC) is a more sensitive biomarker than serum creatinine or estimated glomerular filtration rate. Previous studies have reported altered CysC levels in neurodegenerative disorders and sleep disorders. This study aimed to explore the correlations of serum CysC levels and objective sleep disturbances in early PD. Methods: We recruited 106 early PD patients and 146 age- and sex-matched controls...

Soluble (pro)renin receptor [s(P)RR], which is generated from cleavage of (P)RR, can be detected in plasma and urine. s(P)RR levels can reflect the severity of some diseases, such as renal lesions, gestational diabetes mellitus or hypertension, and obstructive sleep apnea syndrome. However, the relationship between s(P)RR levels and the severity of chronic heart failure remains undetermined. We studied s(P)RR levels in 118 patients with chronic heart failure with reduced ejection fraction (HFrEF), including 86 without renal dysfunction (HF) and 32 with renal dysfunction (HF + RF), and 28 healthy subjects (HS) to reveal the relationship between s(P)RR levels and other HFrEF parameters...

Background: Endothelial dysfunction, a pathophysiologic determinant of atherogenesis, has been found to occur in obstructive sleep apnea syndrome (OSA) and is improved by continuous positive airway pressure (CPAP). However, the efficacy of CPAP therapy is limited by variable adherence. Alternative treatment strategies are needed. The impact of polyphenols on endothelial function has never been evaluated in OSA. Objective: We evaluated the impact of 1-mo supplementation with grape juice polyphenols (GJPs) on the reactive hyperemia index (RHI), a validated measure of endothelial function in patients with severe OSA...

The incidence of new-onset atrial fibrillation (NOAF) is increasing both in the Asian populations and Western countries. Several demographic and clinical risk factors were independently associated with NOAF, including ageing, male sex, obesity, obstructive sleep apnea syndrome, hypertension, coronary artery disease, renal dysfunction and heart failure. However, some differences in the incidence of NOAF, the prevalence of some risk factors and lifestyle or environmental conditions may exist between Asian and Western countries...

BACKGROUND Previous studies have demonstrated that sustained hypoxia in people with obstructive sleep apnea (OSA) impairs upper airway muscle activity, but the underlying mechanism remains poorly understood. As autophagy acts as an important regulator under hypoxia stress, we performed an in vitro investigation of the effects of sustained hypoxia on autophagy of genioglossus muscle-derived stem cells (GG MDSC), an important component of the upper airway muscle. MATERIAL AND METHODS Genioglossus MDSCs were obtained from Sprague-Dawley (SD) rats and identified by using immunofluorescence staining for CD34, Sca-1, and desmin...

The calibrated application of limited duration, cyclic, moderately intense hypoxia-reoxygenation increases cardiac resistance to ischemia-reperfusion stress. These intermittent hypoxic conditioning (IHC) programs consistently produce striking reductions in myocardial infarction and ventricular tachyarrhythmias following coronary artery occlusion and reperfusion, and in many cases, improved contractile function and coronary blood flow. These IHC protocols are fundamentally different from those used to simulate sleep apnea, a recognized cardiovascular risk factor...

Sleep apnea is associated with increased cardiovascular risk and may be important in atrial fibrillation (AF) management. It is present in up to 62% of the AF population and is highly under-recognized and underdiagnosed. Obstructive sleep apnea (OSA) is strongly associated with AF and non-randomized trials have shown that its treatment can help to reduce AF recurrences and maintain sinus rhythm. The 2016 European Society of Cardiology guidelines for the management of AF recommend that AF patients should be questioned regarding the symptoms of OSA and that OSA-treatment should be optimized to improve AF treatment results...

Obstructive sleep apnea syndrome (OSAS) is a common health problem that is associated with abnormality in craniofacial morphology. The growth hormone receptor (GHR) belongs to the cytokine receptor superfamily and mediates the majority of growth hormone signaling, which, among other functions, determines mandibular growth and development. The aim of this study was to determine if correlations exist between single nucleotide polymorphisms (SNPs) in the GHR gene and OSAS in the Han or Hani ethnic groups in China...
