BACKGROUND: Obstructive sleep apnea (OSA) is the most common sleep disorder affecting 2-4 % of the adult population. In addition to several potential mechanisms, inflammation is one of the suggested etiological factors in OSA. Fractalkine/CX3CL1 which is detected in activated or stressed endothelium, smooth muscle cells, skeletal muscle cells, macrophages, neurons, and hepatocytes is an inflammatory marker and attracts attention of sleep specialists in OSA pathogenesis. In this study, we had two goals...

OBJECTIVE: Current standard guidelines for scoring periodic leg movements (PLM) define the start and end of a movement but fail to explicitly specify the movement morphology necessary to classify an EMG event as a PLM, rather than some other muscle event. This is currently left to the expert visual scorer to determine. This study aimed to define this morphology to provide a consistent standard for visual scoring and to improve automatic periodic leg movements in sleep scoring. METHODS: A review of expert PLM scoring produced a hypothesized morphology criterion: a window of high EMG activity within the movement lasting at least 0...

PURPOSE: Physical activity (PA) and sleep are important to health; thus, it is important for researchers to have valid tools to measure them. Accelerometers have been proven valid for measuring PA and sleep, but only one device does this simultaneously: the ActiGraph Link (ActiGraph, LLC); however, the sleep-monitoring function has not been validated. This study aimed to evaluate the predictive power of ActiGraph Link sleep parameters against a validated accelerometer (Actiwatch 2, Phillips Respironics Mini-Mitter)...

BACKGROUND: Statins are considered the most effective drugs used in the treatment of dyslipidemias. Some of their adverse effects are related to muscle problems. Myalgias produced by statins appear more often during exercise. Mandibular advancement devices (MAD) force the propulsory and elevatory musculature of the mandible to exercise by making the jaw move forward. The aim of this study is to evaluate the incidence of muscular side effects (referred, spontaneous, or under palpation pain, myofascial pain, mandibular rigidity and fatigue, tension and sensitivity of the masticatory muscles) in a group of patients with a diagnosis of obstructive sleep apnea being treated with MAD...
