Narcolepsy and IH may also impact the HRQoL of those close to the patient (i.e., partners, parents). This project explored the experiences of partners of people with Narcolepsy or IH, including how living with someone with the diagnoses had impacted their own HRQoL. Methods In this qualitative study, a semi-structured interview was used to collect data from 8 partners of people with Narcolepsy T1, Narcolepsy T2 and IH. The data were analyzed using Reflexive Thematic Analysis to find common themes emerging from the participants’ narratives. Results Five themes (and 2 sub-themes) were identified: 1) changes in dyadic identity; 2) negative impact on intimacy; 3) loneliness; 4) sacrifices to maintain the relationship, and 5) dissatisfaction at the lack of knowledge and information among (a) the general public, and (b) health professionals. Conclusions This novel, exploratory study identified several themes of social and emotional functioning most impacted by a partner’s sleep disorder diagnosis; themes which correspond with the areas shown to be negatively affected in patients. Psychosocial interventions for Narcolepsy and IH should include patients’ partners to reduce the impact of the diagnoses on the family system, and improve overall HRQoL.","PeriodicalId":21861,"journal":{"name":"SLEEP Advances","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136054626","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, screen time is associated with poorer sleep (Janssen et al., 2020), and greater behavioural difficulties (Hinkley et al., 2018), but they are rarely investigated together. Caregivers’ rules and perceptions about screen time are also associated with children’s engagement with screens. Caregivers of preschoolers completed online questionnaires about children’s screen time, sleep-related behaviours (Child Sleep-Wake Scale), behaviour (Child Behavior Checklist (CBCL, 1.5-5)), person-social development (Ages and Stages Questionnaire-3 (ASQ-3)), and questions about their rules and perceptions of screen time. Greater screen times predicted lower personal-social scores, and better sleep-related behaviours predicted lower internalising scores. Greater screen times were predicted by caregivers’ tendency to disagree about limits on screen time and a greater inclination to think limits cause conflict. Lower child personal-social scores predicted caregivers’ tendency to disagree about screen time limits. Greater child externalising behaviours predicted caregivers’ belief that screen time helps calm their child and that time limits cause conflicts. Poorer child sleep also predicted caregivers’ tendency to think screen time limits cause conflict. Therefore, caregivers’ rules and perceptions are associated with children’s screen times, but also children’s behaviours are associated with caregivers’ rules and perceptions about screen time. This is concerning as screen time predicted poorer personal-social behaviours in children. Providing caregivers with alternative ways to manage behaviours and conflicts surrounding time limits could also help in managing children’s screen times. This could have long-term implications for healthy sleep, social, and behavioural development in children.","PeriodicalId":21861,"journal":{"name":"SLEEP Advances","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136054762","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}

To bridge this gap, this study introduces a new sleep dataset which seeks to capture a data-rich, longitudinal snapshot of a representative Australian clinical sleep cohort. Methods Retrospective collation of de-identified sleep clinical records from adult patients who underwent at least one in-lab Type-1 polysomnography between 2012 and 2018 at Canberra Sleep Clinic. We extracted polysomnography raw signals and annotations, as well as medical record information including basic demographics, comorbidities, medications, examination findings, diagnoses, therapy settings and follow-up observations throughout subjects’ time in the Clinic’s care. Records were organised according to a graph database structure, embedding SNOMED terminology encodings wherever possible. Results N=6,777 subjects were included. Gender split (M/F: 62%/38%) and age (51.7±15.3 years) distribution were consistent with typical clinical sleep cohorts. Polysomnography recordings included diagnostic (n=6,635) and non-invasive ventilation titration/therapy (n=2,834), as well as MSLT (n=270) and MWT (n=25) studies.

The use of both NP and TF sensors is reported to be more accurate in respiratory event identification than either alone. However, these sensors can be unreliable if dislodged and cause discomfort. Noxturnal calibrated RIP flow (cRIPflow), derived from RIP, may provide a non-invasive alternative method for flow measurement in identification of respiratory events. Method Respiratory scoring was performed manually by a single experienced scorer on 10 diagnostic sleep studies under AASM standards. Scoring was repeated using three different measurements for each study: cRIPflow only, Thermistor (Th) only and both Th+NP (AASM recommendation). Apnoea hypopnoea index (AHI), central apnoea index (CAI), obstructive apnoea index (OAI), mixed apnoea index (MAI) and hypopnoea index (HI) were calculated and paired t-test analysis utilised for comparison between measurements. Results No statistical differences were identified in comparison of cRIPflow with Th or Th+NP in respiratory event identification: CAI (cRIPflow 3.2/hr±7.1, Th 3.9/hr±8.9, Th+NP 3.1/hr±7.5), OAI (cRIPflow 6.1/hr±6.8, Th 5.3/hr±8.2, Th+NP 6.7/hr±8.9), MAI (cRIPflow 5.2/hr±9.7, Th 4.3/hr±8.7, Th+NP 4.7/hr±9.2), or HI (cRIPflow 12.5/hr±13.9, Th 11.1/hr±10.5, Th+NP 10.4/hr±10.7).

We investigated whether symptom subtypes and/or symptom burden are useful predictors of MACE risk in severe OSA. Method In a longitudinal sleep clinic cohort with apnoea-hypopnoea index ≥30 events/hour (n=1767), we investigated 19 OSA-related symptoms across four symptom domains (upper airway [UA], insomnia and disturbed sleep, morning, and daytime sleepiness) and the Epworth Sleepiness Scale score. Latent class analysis identified five symptom subtypes. A symptom burden score (0–8) was developed by selecting the two symptoms from each domain most strongly associated with MACE. Multivariable-adjusted associations of subtypes and symptom burden with future MACE were investigated using Cox regressions. Results Over a median follow-up of 7 years, 18.7% developed MACE. Relative to the moderately sleepy subtype, the disturbed sleep (adjusted hazard ratio [HR], 1.65; 95%CI, 1.15–2.37) and UA symptoms predominant (HR, 1.57; 95%CI, 1.05–2.34) subtypes showed increased MACE risk. There was a graded increase in MACE risk with increasing symptom burden score (adjusted p for linear trend = 0.003).

The current study examined self-report sleep quality and duration in 21 interns (15 Female, 6 Male, aged 23.0 [20.0, 36.0]) from one Australian Ambulance service. Data were collected quarterly for a year (pre-shift work, and then 3, 6, 9 and 12 months post recruitment training). Linear mixed models, controlling for chronotype and baseline perceived health risk, showed that the first 12 months of shift work were associated with a significant decline in sleep quality (p=0.021) but no change in sleep duration (p=0.76).

Recent studies have demonstrated low pulse wave amplitude drop(PWAD) index to be associated with increased cardiovascular risk in obstructive sleep apnoea(OSA). The nature of PWAD in patients with cardiovascular disease remains unknown. We aimed to characterize PWAD in patients with acute coronary syndrome(ACS) diagnosed with OSA in terms of cardiovascular measures. We studied 70 patients with ACS (age:58[52,63]years, BMI:27[24,30]kg/m2). A level 2 polysomnogram was conducted to confirm OSA diagnosis within 6 months after discharge. Cardiovascular measures of heart rate variability(HRV), baroreflex sensitivity, pulse wave velocity (PWV) and endothelial function(FMD) were measured. PWAD was analysed using a validated algorithm. PWAD with an amplitude reduction of &gt;30% from baseline and a duration &gt;4 heartbeats were identified. PWAD frequency, duration, amplitude, area under the curve(AUC), descending and ascending slopes were calculated. There was no relationship between PWAD frequency and AHI (r=0.057, p=0.642). PWAD amplitude (rs= 0.308, p=0.031) and duration (rs= -0.319, p= 0.025) correlated with baroreflex effectiveness index. After controlling for age, gender and BMI, baroreflex effectiveness index was associated with PWAD duration (β±SE: -0.009±0.003, p=0.009). Aortic augmentation index correlated with PWAD duration (rs= 0.3565, p=0.0041). HRV parameters, FMD and PWV did not correlate with PWAD parameters (data not shown). These preliminary findings suggest PWAD duration and amplitude are not associated with OSA severity in patients with ACS. However PWAD may be appropriate markers of vascular and autonomic nervous system response in patients with cardiovascular disease.","PeriodicalId":21861,"journal":{"name":"SLEEP Advances","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136055103","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}
