ABSTRACT Underpinned by rigorous clinical trial data, the use of existing home sleep apnoea testing is now commonly employed for disordered breathing diagnostics in most centres globally. This has been a welcome addition field given considerable burden disease, cost, and access limitations with in‐laboratory polysomnography testing. However, approaches predominantly aim to replicate elements conventional different forms focus on estimation apnoea‐hypopnoea index. New, simplified technology screening, detection/diagnosis, or monitoring expanded exponentially recent years. Emerging innovations go beyond simple single‐night replication varying numbers signals setting. These novel have potential provide important new insights overcome many transform disease diagnosis management improve outcomes patients. Accordingly, current review summarises evidence study people suspected sleep‐related disorders, discusses emerging technologies according three key categories: (1) wearables (e.g., body‐worn sensors including wrist finger sensors), (2) nearables bed‐embedded bedside (3) airables audio video recordings), outlines their disruptive role care.

The Sleep Opportunity, Need and Ability (SONA) Theory

Journal of Sleep Research, Год журнала: 2025, Номер unknown

Опубликована: Март 6, 2025

'How much sleep does one need?' is a critical question that has been difficult to answer. The long history of research culminated in population-derived normative values 7 9 h per night avoid dysfunction. Such wide range sufficiently large cannot know what required for any given individual. 'Sleep need' currently be directly measured, might not represented by number (given the multiple functions subserves), and likely varies from individual-to-individual day-to-day. This said, concept should embraced can considered alongside more easily operationalised routinely measured constructs 'sleep opportunity' (e.g., time bed) ability' (i.e., obtained sleep, such as duration). Considering dynamics all three together may drive greater understanding about health, insufficiency, disorder pathology. In this article, we describe new theory called Sleep Opportunity, Need, Ability provide rationale why both theoretical clinical value.

Causal Association Between Subtypes of Excessive Daytime Sleepiness and Risk of Cardiovascular Diseases

Journal of the American Heart Association, Год журнала: 2023, Номер 12(24)

Опубликована: Дек. 12, 2023

Excessive daytime sleepiness (EDS), experienced in 10% to 20% of the population, has been associated with cardiovascular disease and death. However, condition is heterogeneous prevalent individuals having short long sleep duration. We sought clarify relationship between duration subtypes EDS outcomes, accounting for these subtypes.

Automated sleep staging on reduced channels in children with epilepsy

Frontiers in Neurology, Год журнала: 2024, Номер 15

Опубликована: Май 10, 2024

Objectives This study aimed to validate a sleep staging algorithm using in-hospital video-electroencephalogram (EEG) in children without epilepsy, with well-controlled epilepsy (WCE), and drug-resistant (DRE). Methods Overnight video-EEG, along electrooculogram (EOG) chin electromyogram (EMG), was recorded between 4 18 years of age. Classical performed manually as ground truth. An end-to-end hierarchical recurrent neural network for sequence-to-sequence automatic (SeqSleepNet) used perform automated three channels: C4-A1, EOG, EMG. Results In 176 stages were scored: 47 74 WCE, 55 DRE. The 5-class accuracy the 84.7% 83.5% those 80.8% DRE (Kappa 0.79, 0.77, 0.73 respectively). Performance per stage assessed an F1 score 0.91 wake, 0.50 N1, 0.83 N2, 0.84 N3, 0.86 rapid eye movement (REM) sleep. Conclusion We concluded that tested has high WCE. acceptable, but significantly lower, which could be explained by tendency more time spent abundant interictal epileptiform discharges intellectual disability leading less recognizable stages.

“Sleep-wake state discrepancy”: toward a common understanding and standardized nomenclature

SLEEP, Год журнала: 2022, Номер 45(10)

Опубликована: Авг. 16, 2022

People with insomnia reporting poorer sleep compared to estimates obtained from objective assessments is common across both research and clinical settings. Typically, individuals report less more wakefulness a given opportunity that captured via methods (e.g. polysomnography) [1–3]. Many different terms have been used describe this phenomenon since the 1970s [4], including but not limited following: misperception [5], sleep-state [6], discrepancy [7], subjective-objective [3], misestimation [8], paradoxical- [9] pseudo-insomnia [4]. The mechanisms underlying are yet well understood [2] require future inform developments in diagnosis treatment (or management) of disorder. aim letter facilitate such work by highlighting recent findings proposing new nomenclature become standard practice for describing phenomenon. Insomnia regarded as “subjective” disorder, which individuals’ perceptions daytime functioning form basis its assessment, diagnosis, treatment. However, measurements may also hold an important role. Clinicians anecdotally reported discussing between perceived objectively measured can be therapeutic. Preliminary [10] support anecdotal evidence, suggesting personalized feedback about self-report (sleep diary) (actigraphy) reduced on subsequent nights group 40 when those who received no [10]. there knowledge underlie implications management insomnia.

Abstract Study Objectives This study was designed to test the utility of cardiovascular responses as markers potentially different environmental noise disruption effects wind farm compared traffic exposure during sleep. Methods Twenty participants underwent polysomnography. In random order, and at six sound pressure levels from 33 dBA 48 in 3 dB increments, three types two road recordings 20-s duration were played established N2 or deeper sleep, each separated by 20 s without noise. Each sequence also included a no-noise control. Electrocardiogram finger pulse oximeter recorded wave amplitude changes pre-noise onset baseline following assessed algorithmically quantify magnitude heart rate vasoconstriction exposure. Results Higher more likely induce drops amplitude. Sound low 39 evoked response (Odds ratio [95% confidence interval]; 1.52 [1.15, 2.02]). Wind with modulation less evoke than other types, but warrants cautious interpretation given numbers replications within type. Conclusions These preliminary data support that are particularly sensitive marker noise-induced during. Larger trials clearly warranted further assess relationships between recurrent activation potential long-term health effects.

Carefully controlled studies of wind turbine noise (WTN) and sleep are lacking, despite anecdotal complaints from some residents in farm areas known detrimental effects other noises on sleep. This laboratory-based study investigated the impact overnight WTN exposure objective self-reported outcomes. Sixty-eight participants (38 females) aged (mean ± SD) 49.2 19.5 were recruited four groups; N = 14, living <10 km a reporting related disruption; 18, no road traffic noise-related 18 control quiet rural area. All underwent in-laboratory polysomnography during full-night conditions random order: night (19 dB(A) background laboratory noise), continuous (25 dB(A)) throughout night; only periods established sleep; wake or light N1 Group, condition, interaction measures quantity quality examined via linear mixed model analyses. There significant condition group-by-noise polysomnographic diary determined outcomes (all ps > .05). These results do not support that at 25 impacts with without prior habitual disruption. findings rule out higher levels potential more sensitive markers ACTRN12619000501145, UTN U1111-1229-6126.
