SHADES Mechanistic Trial
Cardiovascular disease (CVD) is common, deadly, and costly, and adults with insomnia represent a large group of people at elevated risk of developing CVD in the future. This clinical trial will determine if our updated insomnia treatment, called the SHADES intervention, improves CVD factors thought to explain how insomnia promotes CVD and if these improvements are due to positive changes in sleep factors. A total of 200 primary care patients with insomnia and CVD risk factors will be randomized to 6 months of the SHADES intervention (internet, telephonic, and/or face-to-face cognitive-behavioral therapy for insomnia) or the active control condition (sleep education/hygiene, symptom monitoring, and primary care for insomnia). Before and after treatment, participants will complete measurements of the CVD factors (systemic inflammation, autonomic dysfunction, metabolic dysregulation, proinflammatory gene expression) and the sleep factors (insomnia symptoms, sleep onset latency, wake after sleep onset, sleep efficiency). Researchers will test whether the SHADES intervention produces greater improvements in the CVD factors than the active control condition.

Relationship Between Selected Parameters and Bruxism
Bruxism is a common phenomenon. It is estimated that its prevalence in the adult population is 8-31%. Bruxism occurring during sleep is the activity of the masticatory muscles that appear during sleep, which can be rhythmic or phased and is not a movement disorder or sleep disorder in healthy people. It is currently believed that bruxism should not be considered a disorder. In healthy people, it is treated rather as behavior, which may be a risk factor for pathological clinical implications or a protective factor in the presence of other disease entities. The most common symptoms of bruxism include: pathological wear and tooth sensitivity, periodontal and oral mucosa damage, myalgia in the stomatognathic system, headache and prosthetic restoration damage. However, due to nocturnal occurrence, bruxism symptoms may go unnoticed for a long time, which means that patients are often unaware of this behavior. The etiology of bruxism is multifactorial and not fully understood. It is currently believed that it can be caused by genetic, psychological and exogenous factors. Due to the unclear etiology of bruxism, it is so important to conduct research that allows making a certain diagnosis and finding the causes of this phenomenon

A Study to Investigate the Feasibility and Respiratory Effects of Stimulating Two Functional Targets (Neural and/or Muscular) for the Treatment of Obstructive Sleep Apnea
This proof-of-concept study is to collect acute and short-term sub-acute (if applicable) changes in respiratory parameters following the percutaneous placement of electrode arrays. Acute placement and data collection will be conducted while performing a Drug Induced Sleep Endoscopy (DISE) where the goal will be to quantify changes in airflow with stimulation. Data will also be collected during a one- or two-night polysomnography (PSG) to investigate airflow and sleep stability responses with and without different levels of stimulation during sleep. Where feasible, OSA severity data will be collected, as measured via the apnea/hypopnea index (AHI) with stimulation versus without stimulation as a secondary objective. Both data collections will be done when stimulating the hypoglossal nerve (HGN) or Genioglossus muscle (GG) and a second functional target (Ansa Cervicalis - AC) or the strap muscles (sternohyoid and sternothyroid) with a set of electrode arrays either in combination or separately.
