Obstructive sleep apnea (OSA)

This study looked at whether a diabetes drug called empagliflozin, combined with a breathing machine (CPAP), can improve sleep and heart function in 70 adults with both heart failure and obstructive sleep apnea. Participants were randomly assigned to take empagliflozin or not, an…

This study looked at whether weight-loss surgery (sleeve gastrectomy) is better than diet and medication for adults aged 65 and older with severe obesity and related health problems like type 2 diabetes, high blood pressure, sleep apnea, and knee arthritis. Sixty patients chose e…

This pilot study explores whether three different home sleep apnea testing devices—NightOwl, SleepImage, and Nox T3—are practical and user-friendly for adults with type 2 diabetes. Participants will wear each device at home for three nights and answer questionnaires about their e…

Many people with obstructive sleep apnea struggle to use their CPAP machine every night. This trial compares three ways to support them: weekly phone calls from the sleep center, a printed list of frequently asked questions, or the usual care from equipment renters and sleep spec…

This study tested whether a remote patient monitoring platform (MonitAir) could help people with obstructive sleep apnea use their CPAP machine more consistently. 200 adults starting CPAP therapy were randomly assigned to receive standard coaching or enhanced monitoring with the …

Researchers are looking at whether the FIB-4 index, a blood-based score that estimates liver fibrosis risk, tracks with the severity of obstructive sleep apnea (OSA) and low oxygen levels during sleep. They will review records from 373 adults who had full-night sleep studies, gro…

This study tests whether a very short sleep survey, called the Sleep Vital Sign, can help primary care doctors recognize sleep disorders like sleep apnea, insomnia, and restless leg syndrome. About 1,260 adults visiting their Kaiser Permanente doctor will fill out the survey, whi…

This study looked at 103 adults with narcolepsy or obstructive sleep apnea to see if anxiety, social, or work factors affect their ability to stay awake during a standard test. Participants filled out an anxiety questionnaire before the test. The goal is to better understand why …

This study tested a new approach called DREAM, where Veterans at risk for sleep apnea could go straight to home sleep testing without an initial in-person clinic visit. Over 6,500 Veterans took part to see if this speeds up diagnosis and treatment. The goal is to make sleep apnea…

This study looked at how well smartphone apps and a special ring (Belun Ring) can measure sleep quality in adults getting braces or other orthodontic treatment. 52 people from Case Western Reserve University's dental clinic took part. They answered sleep questionnaires and used t…

This completed study observed 563 patients who had weight-loss (bariatric) surgery and received extra oxygen during their first night in the hospital. Researchers tracked how often oxygen levels fell below 90% and what actions nurses took, like adjusting the oxygen flow or reposi…
