It is associated with a wide range of symptoms and complications. Management includes positive airway pressure (PAP), upper airway surgery, oral appliance therapy, positional therapy, and weight loss. Oral appliance therapy treats OSA through direct expansion of the upper airway or indirectly by preventing its collapse. Its effectiveness in improving apnea-hypopnea index and oxygen desaturation is gaining wider approval and the American Academy of Sleep Medicine and the American Academy of Dental Sleep Medicine currently recommend oral appliance as an alternative therapy for those who are unable to PAP therapy. To achieve maximum benefits, it is essential to evaluate factors that can affect treatment outcomes as well as create devices tailored to the individual patient’s dentition and capable of manipulating the degree of mandible advancement. While most are minor and transient, patients should always be warned about the potential adverse effects on mastication and mandibular joint as they can negatively influence treatment compliance. Although PAP shows superior results in improving polysomnography parameters, oral appliance therapy displays comparable health outcomes and greater adherence. Additional studies on establishing patient selection, optimal titration procedure, and measuring objective adherence will further improve oral appliance therapy acceptance.","PeriodicalId":37318,"journal":{"name":"Sleep Medicine Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139130055","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

RBD is young in that it was conceptualized as a distinct clinical disorder by Schenck et al. [1] in 1986, and it is old because it mainly affects older people. In Korea, an RBD case, confirmed by polysom-nography, was reported in 1994. REM sleep without atonia (RWA) on the polysomnography is requisite for RBD diagnosis. Currently, qualitative analysis of RWA is used as RWA quantification is burdensome and time-consuming. Notably, patients complaining of vigorous dreams and violent behaviors are occasionally diagnosed with obstructive sleep apnea or show no definite RWA, which may negate diagnosis based on clinical history or RBD questionnaires. Regarding pathophysiology, dopaminergic degeneration was investigated because of its close relationship with alpha-synucleinopathies. Studies using dopamine transporter (DAT) positron emission tomography (PET) or single photon emission computed tomography (SPECT) showed that dopamine (DA) dysfunction might be implicated in RBD. However, several findings suggest that other pathogenic processes can be involved; 1) in managing RBD symptoms, effectiveness of clonazepam with no influence on DA and little effect of dopaminergic drugs, 2) appearance of RBD in narcoleptic patients, 3) young RBD patients without progression to alpha-synucleinopathies, and 4) RBD symptoms induced by anti-depressants.","PeriodicalId":37318,"journal":{"name":"Sleep Medicine Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139130285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it was not clear whether the reduction in SWS is related to abnormal breathing or the extent of OSA as determined by the minimum oxygen saturation. Further, there is limited research on the relationship between oxygen saturation and SWS. The present study examined the relationship between SWS and minimum oxygen saturation levels in patients with OSA.Methods The sample consisted of 589 patients with OSA (mean age: 48.54 years) who completed full-night polysomnography.Results Results showed that there was a significant difference in SWS scores across three apnea-hypopnea index (AHI) groups (AHI score 5–15 for mild apnea, 16–30 for moderate apnea, and >30 for severe apnea). Lower SWS scores were observed in the severe apnea group. Additionally, results indicated that as oxygen saturation decreased, the SWS scores decreased.Conclusions Results from this study indicate that oxygen saturation significantly predicts SWS amounts. These findings suggest that interventions for low oxygen saturation could enhance the amounts of SWS. The clinical ramifications of these findings are worthy of consideration.","PeriodicalId":37318,"journal":{"name":"Sleep Medicine Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135032138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Autonomic dysfunction may disturb sleep quality by negatively affecting multiple systems, including, but not limited to, the cardiovascular, respiratory, and genitourinary tracts. The current study aims to assess sleep quality and examine the degree of correlation with autonomic nervous function in relatively well-controlled type 2 diabetic patients.Methods This study uses a cross-sectional design to assess sleep quality in 88 type 2 diabetic patients via the Pittsburg Sleep Quality Index (PSQI), accordingly dividing them into two groups: good or poor sleepers. Subsequently, the study evaluates autonomic nerves’ conductivity by measuring electrical skin conductance using Sudoscan for the hands and feet.Results Of 88 recruited patients, 53% showed poor sleep quality, with higher incidence in females. Autonomic nerve conductivity showed moderate damage in poor sleepers with 59.53 ± 13.35 μS and 59.68 ± 16.91 μS of hand and foot electrodes, respectively. Autonomic damage induces sleep disturbance mainly through increased nighttime voiding in 91.49% of the poor sleepers group compared to 41.46% in the good sleepers group. PSQI score was found to strongly and inversely correlate with autonomic nerve conductivity via hand electrodes, with a correlation coefficient of -0.62 and a determination coefficient of 0.39.Conclusion Poor sleep quality seems to be a significant problem even in relatively well-controlled type 2 diabetic patients with no diagnosed micro- or macrovascular complications. Autonomic dysfunction negatively affects the quality of sleep and leads to sleep disturbance by increasing nighttime micturition as one of its complications.","PeriodicalId":37318,"journal":{"name":"Sleep Medicine Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135032135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These repeated breathing disruptions can result in intermittent hypoxia, hypercapnia, hyperactivity of the sympathetic nervous system, and fragmented sleep patterns. Left untreated, OSA can have significant health implications, including various symptoms and serious consequences. Positional OSA is a subtype of OSA where during sleep, the severity of apnea events is significantly higher in the supine position. This condition can worsen respiratory parameters, such as apnea/hypopnea events, oxygen desaturation and arousals, and cardiovascular burdens. Positional therapy is a treatment approach used for patients with positional OSA. Typically, positional therapy involves encouraging the patient to avoid sleeping on their back, and instead sleep in a lateral position. Various modalities for positional therapy exist, including positional training using a tennis ball, alarm, or vest, and sleep positioning pillows. Novel electric-operated postural devices have also been developed. Positional therapy has shown promise in improving apneic events and lowest oxygen saturation in patients with position-dependent sleep apnea. In comparison to positive airway pressure treatment, positional therapy has been reported to demonstrate non-inferior effects, while achieving better compliance. Consequently, positional therapy can be a cost-effective and non-invasive therapeutic alternative for managing positional OSA.","PeriodicalId":37318,"journal":{"name":"Sleep Medicine Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135032136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
