Disturbed sleep, a hallmark symptom of PTSD, impairs fear extinction recall. However, our understanding of the electrophysiological mechanisms underpinning sleep's role in extinction retention remains underdetermined. We examined the relationship between the microarchitecture of sleep and extinction recall in healthy humans (n = 71, both male and females included) and a pilot study in individuals with PTSD (n = 12). Participants underwent a fear conditioning and extinction protocol over 2 days, with sleep recording occurring between conditioning and extinction. Twenty-four hours after extinction learning, participants underwent extinction recall. Power spectral density (PSD) was computed for pre- and post-extinction learning sleep. Increased beta-band PSD (~17-26 Hz) during pre-extinction learning sleep was associated with worse extinction recall in healthy participants (r = 0.41, p = .004). Beta PSD was highly stable across three nights of sleep (intraclass correlation coefficients > 0.92). Results suggest beta-band PSD is specifically implicated in difficulties recalling extinguished fear.</p>","PeriodicalId":49514,"journal":{"name":"Sleep","volume":" ","pages":""},"PeriodicalIF":5.3,"publicationDate":"2023-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10566240/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10297707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Substantial weight loss in patients with obesity-related OSA can reduce or even eliminate OSA as well as reduce sleepiness and improve cardio-metabolic health. Evidence suggests that these improvements exceed those that occur with device-based OSA therapies like continuous positive airway pressure which continue to be the first-line of therapy. Resistance to weight management as a first-line strategy to combat OSA could arise from the complexities in delivering and maintaining adequate weight management, particularly in sleep clinic settings. Recently, incretin-based pharmacotherapies including glucagon-like peptide 1 (GLP-1) receptor agonists alone or combined with glucose-dependent insulinotropic polypeptide (GIP) receptor agonists have been developed to target glycemic control in type 2 diabetes. These medications also slow gastric emptying and reduce energy intake. In randomized, placebo-controlled trials of these medications in diabetic and non-diabetic populations with obesity, participants on active medication lost up to 20% of their body weight, with corresponding improvements in blood pressure, lipid levels, physical functioning, and fat mass loss. Their adverse effects are predominantly gastrointestinal-related, mild, and transient. There are trials currently underway within individuals with obesity-related OSA, with a focus on reduction in weight, OSA severity, and cardio-metabolic outcomes. These medications have the potential to substantially disrupt the management of OSA. Pending coming data, we will need to consider pharmacological weight loss as a first-line therapy and how that influences training and management guidelines.</p>","PeriodicalId":49514,"journal":{"name":"Sleep","volume":" ","pages":""},"PeriodicalIF":5.6,"publicationDate":"2023-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11009690/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10258018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Novel insights into the role of eye movements during REM sleep in memory consolidation.","authors":"Michele Ferrara,&nbsp;Aurora D'Atri,&nbsp;Federico Salfi","doi":"10.1093/sleep/zsad178","DOIUrl":"10.1093/sleep/zsad178","url":null,"abstract":"A large and consistent literature converges in pointing out how hippocampus-dependent memories benefit from slow wave activity during non-rapid eye movement sleep (NREM). The declarative memory traces are repeatedly reactivated during slow-wave sleep (SWS), promoting long-term storage at the cortical level [1, 2]. Sleep also supports the consolidation of procedural memory underlying problem-solving and the acquisition of new rules or cognitive strategies [3–5], but in this context, the specific role of SWS is more controversial. While some studies support the possible involvement of SWS [6, 7], others propose rapid eye movement (REM) sleep as the main responsible for the sleep-dependent integration of information supporting creative problem solving [8]. Meanwhile, the iterative and synergic interleaving of REM and NREM stage characteristics has been recently conceptualized to explain the sleep effect on creative problem-solving skills [3]. However, evidence of specific cortical processes representing the actual reactivation of this kind of memories during paradoxical sleep is still scarce. Another gap in the literature addressing the relationship between REM sleep and memory function is represented by the common practice of considering paradoxical sleep as a homogeneous state, especially in human studies [9]. However, from decades, two neurophysiologically distinct REM substates have been identified [9, 10], namely the tonic and phasic REM sleep, and the available literature suggested a functional heterogeneity of these two substates in memory consolidation [11–13]. In the August issue of SLEEP, van den Berg and collaborators [14] addressed some of these open and scarcely explored questions, providing novel insight into the role of the electroencephalographic (EEG) activity during human tonic and phasic REM sleep in the consolidation of novel problem-solving skills. Two different groups of healthy young participants (n = 20 per group) performed the Tower of Hanoi task before and after (1) an undisturbed 8-hour period of sleep, or (2) a same-length wake period. Each group also took part in another similar condition (in counterbalanced order) in which a non-learning control task was performed. The study [14] adopted a quite novel approach to address the involvement of REM sleep in memory consolidation, evaluating the event-related spectral perturbations (ERSP) time-locked to the eye movement (EM) peaks. This analysis allowed the authors to estimate specific oscillatory EEG components surrounding EMs during REM sleep, unraveling stable cortical patterns associated with EMs in the post-learning night compared with the control (non-learning) condition. Furthermore, the authors [14] classified the EMs during REM sleep into “bursts,” defining phasic REM state, and “isolated” EMs, proposed as a proxy of tonic REM state. This categorization led to evaluating the differential contribution of phasic and tonic REM sleep to the consolidation of problem-solvin","PeriodicalId":49514,"journal":{"name":"Sleep","volume":" ","pages":""},"PeriodicalIF":5.6,"publicationDate":"2023-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10566246/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10338022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods In the parent study (RESTFUL), adults with refractory RLS were randomized to active TOMAC or sham for 4 weeks followed by 4 weeks of open-label active TOMAC. In the extension study, earlier RESTFUL completers comprised the control group (n = 59), which was followed for 24 weeks with no TOMAC intervention, and later RESTFUL completers compromised the treatment group (n = 44), which received 24 additional weeks of open-label active TOMAC followed by no intervention for 8 weeks. The primary endpoint was Clinician Global Impressions-Improvement (CGI-I) responder rate at week 24 compared to RESTFUL entry. Results CGI-I responder rate improved from 63.6% (95% CI, 49.4 to 77.9%) at RESTFUL completion to 72.7% (95% CI, 58.2 to 83.7%) at week 24 for the treatment group versus 13.6% (95% CI, 7.0 to 24.5%) at week 24 for the control group (p < 0.0001). Mean change in International RLS Rating Scale (IRLS) score improved from −7.4 (95% CI, −5.6 to −9.2) at RESTFUL completion to -11.3 points (95% CI, −8.8 to −13.9) at week 24 for the treatment group versus −5.4 (95% CI, −3.7 to −7.2) at week 24 for control group (p = 0.0001).
