BACKGROUND: Sleep deprivation after major surgery is common and associated with worse outcome. Noise is one important reason for sleep fragmentation, which contributes to enhanced morbidity. The purpose of this work was to evaluate the impact of earplugs on patients' sleep quality during their first night after cardiothoracic surgery to eventually improve an existing fast-track concept. METHODS: Sixty-three patients undergoing cardiothoracic surgery eligible for a postoperative fast- track regimen on our cardiothoracic post anaesthesia care unit (C-PACU) were prospectively included...

Meis homeobox 1 (Meis1) is a transcription factor functioning in the development of the nervous system and the cardiovascular system. Both common and rare variants within the gene have been associated with restless legs syndrome (RLS), while its association with symptoms of insomnia has also been discovered recently. RLS is associated with sleep disturbances, and while Meis1 haploinsufficiency is one of the most promising strategies for an RLS animal model, sleep phenotyping of Meis1 knockout mice has never been conducted...

Snoring, chronic rhinitis and fragmentation of sleep are common symptoms in pregnancy, especially in the third trimester. The prevalence of obstructive sleep apnea is also increased in pregnant women and can be associated with pregnancy induced hypertension, preeclampsia and diabetes mellitus. The fetus is as well exposed to a higher risk of prematurity and intra-uterine growth restriction. Given the lack of adequate screening tool, the diagnosis of obstructive sleep apnea is a challenge for the physician and a high degree of clinical suspicion is necessary in order to identify the patients at risk and propose an appropriate management...

Obstructive sleep apnea (OSA) is a highly prevalent sleep breathing disorder characterized by intermittent hypoxia (IH), leading to blood hypoxemia, hypercapnia, and sleep fragmentation. Studies on the effects of OSA on oral epithelial tissue healing are limited. Smoking is considered a risk factor for OSA through the exposure to chemically active toxins, present in the smoke. Acrolein is the most chemically active unsaturated aldehyde, impairing a variety of biological processes. The aim of this study was to determine the effect of IH on oral epithelial tissue healing, with and without acrolein...

Obstructive sleep apnea (OSA), the most severe form of sleep disordered breathing, is characterized by intermittent hypoxia during sleep (IH), sleep fragmentation, and episodic hypercapnia. OSA is associated with increased risk for morbidity and mortality affecting cardiovascular, metabolic, and neurocognitive systems, and more recently with non-alcoholic fatty liver disease (NAFLD) and cancer-related deaths. Substantial variability in OSA outcomes suggests that genetically-determined and environmental and lifestyle factors affect the phenotypic susceptibility to OSA...

OBJECTIVES/BACKGROUND: Because both REM sleep behavior disorder (RBD) and Obstructive Sleep Apnea (OSA) can present with similar symptoms, it is important to understand the influence of OSA in the clinical manifestations of RBD and whether RBD modulates OSA severity. Our objectives were to compare: 1. the intensity of non-motor symptoms between RBD patients with (RBD-OSA) and without OSA (RBD-non-OSA), and 2. polysomnographic features between RBD-OSA and OSA without RBD (OSA-non-RBD) patients...

INTRODUCTION: The effects of obstructive sleep apnea (OSA) on the metabolic system are not well understood, especially in children. Recent studies have provided evidence of the modulation of insulin action by branched-chain amino acids (BCAAs) and suggested novel mechanistic relationships between glucose and amino acid metabolic pathways. We hypothesized that plasma BCAA levels may serve as biomarkers of insulin resistance and metabolic dysfunction in children with OSA. METHODS: A polysomnography was conducted for the diagnosis of OSA in 90 snoring children, in a tertiary hospital...

Abnormal sleep may associate with cognitive decline in Parkinson's disease (PD). Furthermore, sleep dysfunction may associate with worse motor outcome. We hypothesised that PD patients with poor quality sleep would have greater progression in gait dysfunction, due to structural and functional overlap in networks subserving sleep and gait regulation. 12 PD patients and 12 age-matched controls completed longitudinal follow-up over 36 months. Poor sleep efficiency and greater sleep fragmentation correlated significantly with progression of step-width variability, a gait characteristic mediated by postural control, providing evidence that poor sleep in PD is associated with a more rapid deterioration in gait...

Narcolepsy type 1 is a life-long, severe, multifaceted disease often arising in childhood or adolescence. Beyond the classical symptoms (excessive daytime sleepiness, cataplexy, hallucinations, sleep paralysis and nocturnal fragmented sleep), metabolic, endocrinological, psychiatric and psychosocial aspects must be considered. Despite the increased awareness after H1N1 pandemic influenza and vaccination, narcolepsy is still misdiagnosed and unrecognized. The peculiar presentation of symptoms in narcoleptic children could in part explain the misdiagnoses...

BACKGROUND: Fragmented QRS (fQRS) has been shown to be associated with poor outcome in various cardiovascular diseases. Non-dipper hypertension is also associated with increased cardiovascular mortality. The aim of our study is to investigate the relationship between fQRS and non-dipper status in hypertensive patients without left ventricular hypertrophy (LVH). METHODS: This study included 106 hypertensive patients without LVH. Patients were divided into two groups: dipper hypertension and non-dipper hypertension...

Study Objectives: Sleep fragmentation (SF) is highly prevalent and has emerged as an important contributing factor to obesity and metabolic syndrome. We hypothesized that SF-induced increases in protein tyrosine phosphatase-1B (PTP-1B) expression and activity underlie increased food intake, inflammation, and leptin and insulin resistance. Methods: Wild type (WT) and ObR-PTP-1b-/- mice (Tg) were exposed to SF and control sleep (SC), and food intake was monitored...

Physiological evidence suggests that sleep modulates kidney function. Our objective was to examine the cross-sectional association between kidney function and objectively-estimated habitual sleep duration, quality and timing in a cohort of patients with mild to moderate chronic kidney disease. This study involved two US clinical centers of the Chronic Renal Insufficiency Cohort (CRIC) study, including 432 participants in a CRIC ancillary sleep study. Habitual sleep duration, quality and timing were measured using wrist actigraphy for 5-7 days...

Apart from the typical motor symptoms, Parkinson's disease is characterized by a wide range of different non-motor symptoms, which are highly prevalent in all stages of the disease and have an incisive influence on quality of life. Moreover, their treatment continues to be challenging. In this review, we critically summarize the evidence for the impact of dopaminergic therapies on non-motor symptoms in Parkinson's disease. We performed a PubMed search to identify relevant clinical studies that investigated the response of non-motor symptoms to dopaminergic therapy...

The article presents the results of a polysomnographic study with simultaneous monitoring spontaneous nocturnal erections - Nocturnal Penile Tumescences (NPT) in 69 men with age-related androgen deficiency (AAD). Of these, 45 patients were diagnosed with obstructive sleep apnea syndrome (OSAS). In 34 of the 45 patients with OSAS, regimens of non-invasive ventilation with positive-positive airway pressure (CPAP) were selected. Titration was carried out using automatic CPAP-devices for 2 months. The control group (n=24) comprised men with AAD, matched by the "copy-pair" type without clinical manifestations of respiratory disturbances during sleep...
