New data presented today at the Annual Meeting of the American Academy of Otolaryngology confirm that specialized oral appliances are a viable option to counter the devastating effects of obstructive sleep apnea (OSA) and new FDA-approved technologies for home-based sleep studies are a valuable tool to diagnose and assess the effectiveness of the therapy.
Obstructive sleep apnea syndrome (OSAS) is a disorder characterized by repeated episodes of reductions or cessation in breathing during sleep. Millions of Americans, both men and women, have this medical problem, which is associated with clinical complications such as daytime sleepiness, high blood pressure (hypertension), heart disease, increased risk for stroke, and an increased risk for early death.
The gold-standard method to diagnose and quantify OSA is considered the overnight sleep polysomnography (PSG). With this system, patients spend the night in a sleep lab while hooked to a variety of electrodes, which measure various channels (such as EEG, EOG, EMG, ECK, Flow, Respiratory Effort, Oximetry). The severity of the disorder is expressed as the respiratory disturbance index (RDI), which is the number of sleep disordered breathing events per hour of sleep.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
