Automated measure of nighttime oxygen levels could speed diagnosis of sleep apnea

(University of Chicago Medical Center) Computer analysis of oxygen levels in the blood during sleep could -- by itself -- provide an easy, relatively inexpensive and sufficiently reliable way to determine which children who snore habitually could benefit from a diagnosis and treatment for obstructive sleep apnea. This approach was most accurate for children with severe apnea.

Conclusions:Snore sounds carry sufficient information to detect the presence of OSA during NREM and REM sleep. Because the methods used include technology that is fully automated and sensors that do not have a physical connection to the patient, it has potential for OSA screening in the home environment. The accuracy of the method can be improved by developing sex-specific models.Citation:Akhter S, Abeyratne UR, Swarnkar V, Hukins C. Snore sound analysis can detect the presence of obstructive sleep apnea specific to NREM or REM sleep.J Clin Sleep Med. 2018;14(6):991–1003.

Abstract Background: Mandibular advancement devices (MAD) are effective in reducing apnea episodes and they are frequently used as first-line therapy in obstructive sleep apnea (OSA) patients. Objectives: The MAD must be used every night for a lifetime and since it performs its function discharging the forces on dental elements the aim of this systematic review was to identify the dental and skeletal long-term side effects of MAD therapy and to evaluate the influence of time on them in OSA or snoring patients. Search Methods: An electronic search was performed in MEDLINE, Cochrane Database, Google Schola...

Objective: To determine the prevalence of obstructive sleep apnea (OSA) in a prospective cohort of patients with spontaneous CSF (sCSF) leaks of the temporal bone. Study Design: Prospective cohort study. Setting: Tertiary referral center. Patients: Consecutive sCSF leak patients (21) over a 3-year period. Four patients presented with a history of OSA and 17 patients were prospectively offered polysomnogram (PSG) testing during the initial clinic encounter. Intervention: Level I PSG. Main Outcome Measures: Patient characteristics (age, sex, body mass index), apnea hypopnea index (AHI), presence of snoring, and...

AbstractPurposeUpper airway stimulation (UAS) is an alternative second-line treatment option for patients with obstructive sleep apnea (OSA). In our substudy of a previous multicentre study of patients implanted with UAS, we focused on patient-related outcomes like Epworth Sleepiness Scale (ESS), the Functional Outcomes of Sleep Questionnaire (FOSQ), snoring and personal satisfaction 6 and 12  months after the implantation.Methods60 patients, who were initially non-adherent to CPAP and implanted with UAS, were included in a prospective multicentre study. Data were collected preoperative, 6 and 12  months after im...

AbstractYoga is an ancient Indian practice of mental and physical exercises (syn: asanas), postures (syn: mudras), movements and breathing techniques which sustain healthy living of the body and the mind. It incorporates various exercises of breathing, oropharyngeal structures and facial expressions, the physiology and effect of which are comparable to international physiotherapy recommendations in treatment of obstructive sleep apnea (OSA) i.e. to preserve upper airway patency by maintaining airway dilator muscle tone. Preliminary results show that yoga can be an effective and constructive alternative to physiotherapy for...

AbstractBackgroundRetropalatal region might be considered the most common site of obstruction in patients with snoring and OSA. We aimed at presentation of two combined techniques: modified anterior palatoplasty (MAP) and bilateral double suspension suture (DSS).MethodsThis prospective study was conducted on OSA patients with retro-palatal collapse only that was confirmed by nasoendoscopy during Muller ’s maneuver and drug induced sleep endoscopy. MAP and DSS were performed for all patients. Preoperative and 6 months after surgery, all patients underwent fiber-optic nasoendoscopy using the Muller maneuver and po...

(Umea University) People who snore may have extensive tissue damage in the nerves and muscles of the soft palate. This can in turn create problems with swallowing and contribute to development of sleep apnea. Treatment strategies aimed at early intervention to stop snoring might have beneficial effects in healing or preventing development of sleep apnea. These findings are explained in a new dissertation at Ume å University, Sweden.
