ObjectivesHigh rates of sleep difficulties have been found in patients with advanced cancer. However, not much is known about factors that are associated with sleep impairments in this population and that could constitute their potential risk factors or consequences. This study conducted in patients with cancer receiving palliative care aimed to evaluate the relationships of subjective (sleep diary; Insomnia Severity Index, ISI) and objective (actigraphy) sleep–wake variables with several physical and psychological symptoms, maladaptive sleep behaviours, erroneous beliefs about sleep, quality of life, time to death and environmental factors.MethodsThe sample was composed of 57 community-dwelling patients with cancer receiving palliative care and with an Eastern Cooperative Oncology Group Scale score of 2 or 3. Actigraphic, light and sound recording and a daily sleep and pain diary were completed for seven consecutive days. A battery of self-report scales was also administered.ResultsGreater disruptions of subjective and objective sleep–wake variables were more consistently associated with worse physical symptoms than with psychological variables. Disrupted objective sleep–wake parameters were also associated with a greater frequency of maladaptive sleep behaviours. Finally, a greater nocturnal noise in the bedroom was correlated with more impairments in subjective and objective sleep–wake variables while a lower 24-hour light exposure was associated with more disruption of subjectively assessed sleep only.ConclusionsAlthough longitudinal studies are needed to establish the etiology of sleep–wake difficulties in patients with advanced cancer, our findings suggest that physical symptoms, maladaptive sleep behaviours and environmental factors can contribute to their development or their persistence and need to be adequately addressed.

Abstract Introduction Disrupted nighttime sleep (DNS) is a core narcolepsy symptom subjectively described as spontaneous awakenings during the night, but researchers use varied polysomnogram (PSG) definitions based on sleep state transitions, NREM 1% and poor sleep efficiency. These sleep measures have yet to be validated to determine the best objective measure of DNS. Furthermore, it unknown to what extent DNS occurs in pediatric narcolepsy as children have greater sleep drive than adults. Here, we assess the construct validity of various DNS objective measures and evaluate its diagnostic utility for pediatric Narcolepsy Type 1 (NT1) when combined with a nocturnal Sleep Onset REM period (nSOREMP) in a large cohort of pediatric patients with CNS hypersomnias. Methods Retrospective, cross-sectional study of consecutive PSGs and multiple sleep latency tests (MSLTs) obtained at Boston Children’s Hospital and University of Bologna. Participants were drug-free or drug naïve, ages 6-18 years and slept at least 6 hours during the PSG. We analyzed associations between objective DNS measures and outcomes of self-reported sleep disturbance, Epworth Sleepiness Score, mean sleep latency, NT1 diagnosis, and CSF hypocretin values when available. We then combined the best performing DNS measure with the presence of a nSOREMP to determine the diagnostic value for NT1 using bootstrap analysis. We included n=151 NT1, n=21 narcolepsy type 2 (NT2), n=27 idiopathic hypersomnia (IH) and n= 117 subjectively sleepy controls in this analysis. Results Across groups, the Wake and NREM 1 bouts index had the most robust associations with objective sleepiness, subjective sleep disturbance and CSF hypocretin levels (p’s <0.0001). From 1000 bootstrap samples, the Wake/N1 index and presence of a nSOREMP have greater diagnostic accuracy for NT1 than the nSOREMP alone (p<0.0001). Conclusion Among a variety of sleep quality measures, we find that a Wake and NREM 1 bout index is the best objective measure of DNS. In combination with a nSOREMP, this DNS measure can aid in pediatric NT1 diagnosis using PSG alone and potentially reduce diagnostic delays.

Abstract Introduction While sleep duration is known to affect next-day cognitive performance and alertness, largely in a dose-response manner, the effects of disrupted sleep (where one is awoken multiple times overnight, common in military settings) are much less understood. Therefore, we examined the effects of experimentally disrupted sleep on morning cognitive performance and alertness. Methods We tested 34 healthy participants (12 men, 22 women, 28.1±3.9 years; mean±SD) who slept for 8-hours time-in-bed on three consecutive nights with polysomnography in a controlled sleep lab. The final two nights were randomized and counterbalanced between an undisrupted and a disrupted sleep condition. On the disrupted sleep night, participants were awoken by auditory tones for a 5–10 min period every hour. The following morning, participants completed a cognitive test battery that included Karolinska Sleepiness Scale (KSS), 10-min psychomotor vigilance task (PVT), addition calculations (ADD), go/no-go (GNG), task switching (TS), and working memory (WM). Mixed effects models were used to test factors: condition (undisrupted vs. disrupted), condition-order, and their interaction. Results Significant (p<0.05) effects of condition (i.e., disrupted sleep caused worse performance) were found for PVT reaction time (RT), GNG RT, TS RT, WM percent correct, and KSS alertness ratings. Condition was not significant for number or percent correct on ADD, GNG, and TS. Condition-order was significant for TS percent correct, and significant interactions were found for ADD number correct and TS RT. Conclusion One night of sleep disruption caused significant negative effects on morning subjective alertness and on several, but not all, cognitive performance domains tested, including RT and WM. Condition-order and interaction effects were also found, indicating that some performance outcomes were impacted by possible learning effects over the study. Sleep disruption factors should be taken into account, especially in operational settings like the military where environmental factors (e.g., noise) disrupt sleeping conditions.

AbstractObjective:Prevalence rates of sleep difficulties in advanced cancer patients have varied widely across studies (12 to 96%), and none of these employed a diagnostic interview to distinguish different types of sleep–wake disorders. Moreover, very limited information is available on subjective and objective sleep parameters in this population. Our study was conducted in palliative cancer patients and aimed to assess rates of sleep–wake disorders and subsyndromal symptoms and to document subjective and objective sleep–wake parameters across various types of sleep–wake difficulties.Method:The sample was composed of 51 community-dwelling cancer patients receiving palliative care and having an Eastern Cooperative Oncology Group score of 2 or 3. Relevant sections of the Duke Interview for Sleep Disorders were administered over the phone. An actigraphic recording and a daily sleep diary were completed for 7 consecutive days.Results:Overall, 68.6% of the sample had at least one type of sleep–wake difficulty (disorder or symptoms): 31.4% had insomnia and 29.4% had hypersomnolence as their main sleep–wake problem. Participants with insomnia as their main sleep difficulty had greater disruptions of subjective sleep parameters, while objectively-assessed sleep was more disrupted in patients with hypersomnolence comorbid with another sleep–wake difficulty.Significance of the Results:The high rates of sleep–wake difficulties found in this study indicate a need to screen more systematically for sleep–wake disorders, including insomnia and hypersomnolence, in both palliative care research and clinical practice, and to develop effective nonpharmacological interventions specifically adapted to this population.

Abstract Introduction During the past years, an increasing number of articles has focused on comparing sleep in youths with and without ADHD. However, so far no meta-analysis has been conducted summarizing the findings. Therefore, the current study assesses sleep architecture (i.e. the basic sleep structure), sleep problems, and sleep hygiene. Sleep was assessed both subjectively and objectively and the two groups were compared on multiple variables. Methods Two researchers independently performed a literature search (1980–2020). Studies using a case-control design comparing sleep in youths (12–25 years) with and without ADHD were included. Study quality was evaluated using the Newcastle-Ottawa Scale. Standardized mean differences were calculated for each outcome domain being reported by at least two studies. Results 10379 publications were screened, resulting in 11 studies and 52 effect sizes (nADHD=2377, ncontrol=21687). These effect sizes were summarized into 7 objective and 11 subjective variables measuring sleep. Two objective sleep variables were significantly worse in the ADHD group; total sleep time (z=2.16, p=.03) and sleep onset latency (z=2.39, p=.02). The two groups did not differ on sleep efficiency, sleep onset/offset time, and time in bed. Comparing the groups on subjective variables resulted in the same pattern, with total sleep time (z=21.27, p<.001) being significantly shorter in the ADHD group, and sleep onset latency (z=15.39, p<.001) and wake after sleep onset (z=13.50, p<.001) being significantly longer. Additionally, the ADHD group reported a significantly lower sleep efficiency (z=20.15, p<.001) and subjective sleep satisfaction (z=3.50, p<.001). Wake time and number of awakenings during the night were not significant. Youths with ADHD also reported significantly more sleep problems, including insomnia (z=6.38, p<.001), daytime sleepiness (z=26.68, p<.001) and sleep disturbances (z=8.00, p<.001). Due to only two studies measuring it, with a focus on different variables, sleep hygiene could not be included. Conclusion In general, youths with ADHD have a disrupted sleep architecture and experience more sleep problems compared to their typically developing peers. Consequently, sleep assessment should become a routine part during the diagnostic process of ADHD. Additionally, more research is needed focusing on sleep architecture and sleep hygiene, and on the development of a sleep intervention for youths with ADHD. Support (if any):

Abstract Introduction Sleep is critical to children’s health and recovery, but pediatric inpatient sleep is often disrupted by nonessential overnight interruptions. The COVID-19 pandemic necessitated social distancing policies which minimized contact with low-risk patients. These policies have the potential to decrease overnight disruptions and improve sleep for hospitalized patients. Methods This cohort study compared sleep disruptions for pediatric inpatients admitted prior to (Sep 2018 – Feb 2020) and during (Apr 2020 – Aug 2020) the COVID-19 pandemic at a single site, urban academic medical center. Objective disruptions were measured as room entries detected by hand hygiene sensors for occupied rooms pre-pandemic (n_average=56) and during the pandemic (n_average=48) for 69 and 154 nights, respectively. Subjective reports of overnight disruptions, sleep quantity, and caregiver mood were measured by surveys adopted from validated tools: the Karolinska Sleep Log, Potential Hospital Sleep Disruptions and Noises Questionnaire, and Visual Analog Mood Scale. Caregivers of a convenience sample of pediatric general medicine inpatients completed surveys. Caregivers pre-pandemic were surveyed in person, and during the pandemic, surveys were conducted over the phone. Results 293 pre-pandemic (age_patients=4.1±4.4 years) and 154 pandemic (age_patients=8.7±5.6 years) surveys were collected from caregivers. The majority (71% pre-pandemic and 52% pandemic) of the study population identified as Black/African American. Nighttime room entries initially decreased 36% (95% CI: 30%, 42%, p<0.001), then returned towards pre-pandemic levels as the COVID-19 hospital caseload decreased. Despite this, caregivers reported more disrupted patient sleep (p<0.001) due to tests (21% vs. 38%) as well as stress (30% vs. 49%), anxiety (23% vs. 41%), and pain (23% vs. 48%). Caregivers also reported children slept 61 minutes less (95% CI: 12 min, 110 min, p<0.001) and had more awakenings. Caregivers self-reported feeling more sad and weary, less calm, and worse overall (p<0.001 for all). Conclusion Despite fewer objective room entries, caregivers reported increased sleep disruptions and an hour less nighttime sleep with more awakenings during the pandemic for pediatric patients. Caregivers also self-reported worse mood. This highlights the importance of addressing subjective perceptions and experiences of hospitalized children and their caregivers during hospitalization.

410 Background: Sleep disruption is a prevalent problem among cancer patients and survivors, but clinical correlates of poor sleep are understudied, especially in colorectal cancer. We recently showed that metastatic breast cancer patients with poor sleep efficiency have a shorter overall survival. The primary study objective is to clarify the relationship between subjective sleep disruption and survival in patients with metastatic colorectal cancer (MCC). Methods: 240 pts (63% male, mean age=59; SD=11.0) treated for MCC in 1st to 5th line of 5-fluorouracil based chemotherapy completed the QOL Questionnaire (EORTC QLQ-C30). We considered sleep to be disrupted if patients reported little to severe trouble sleeping (scores >0 ). Multivariate Cox models included age, gender, site of primary tumor, stage at diagnosis, number of metastatic sites, performance status and prior chemotherapy. Results: 65.4% of the patients reported mild to severe sleep disruption according to EORTC QLQ-C30. Patients with trouble sleeping had poorer overall survival as compared to those without sleep disruption (HR: 1.47 [1.11 to 1.95]; p=0.008). Respective median survival times (months) were 14.2 [95% CI: 12.3 to 16.1] and 17.7 [10.0 to 25.3]. The survival benefit observed in patients without sleep disruption remained statistically significant after adjustment for other prognostic factors. The final multivariate prognostic model included subjective sleep disruption (HR: 1.49 [1.11 to 2.00]; p=0.009), number of metastatic sites (p<0.001), performance status (p=0.023), and prior chemotherapy (p<0.001). Conclusions: Our findings show that patients reported sleep disruption is an independent prognostic factor for overall survival in MCC. Future research is needed to determine the mechanisms of sleep disruption and its effect on survival, and whether treatment of sleep disruption can improve survival in MCC.

The prevalence of moderate-to-severe sleep problems is significantly higher among people with multiple sclerosis (MS) than in the general population. In 2002, we found a significant relationship between fatigue and disrupted sleep in patients with relapsing-remitting MS (RRMS). The objectives of this study were to determine whether eszopiclone (Lunesta; Sunovion Pharmaceuticals Inc, Marlborough, MA) was superior to placebo in improving sleep among patients with MS-related fatigue and sleep complaints (primary end point); and to assess the impact of improved sleep on daytime fatigue and functioning (secondary end point). This was a double-blind, placebo-controlled pilot trial lasting 7 weeks. Thirty ambulatory adults under age 65 years with RRMS, fatigue, and sleep disturbances were randomized to receive either eszopiclone or placebo. The outcome measures included subjective and objective changes in sleep-onset latency (SOL), total sleep time (TST), wakefulness after sleep onset (WASO), sleep efficiency (SE), fatigue scales, and neuropsychological measures of daytime functioning. Compared with placebo, eszopiclone was superior only in increasing TST. Fatigue improved in both groups, but there was no statistically significant correlation between increased TST and improved fatigue, and no statistically significant differences were observed between the two groups. Thus, in this study, eszopiclone did not improve sleep sufficiently to improve fatigue in MS patients. This result may be due to the multifactorial nature of sleep disturbances and fatigue in people with MS.

Method: In this study participated 270 university students (193 women, 71.5%, 77 men, 28.5%), aged between 17 and 53 years (M = 21.69, SD = 5.263). For the data collection, were applied the Resilience Questionnaire (Oliveira, M. & Machado, T. S., 2009) and the Subjective Sleep Disorder measures (Azevedo et al., 2010). Results: More than half of the students presented subjective sleep disturbance expressed in initial, intermediate, terminal, and subjective insomnia. The Personal Competence 6 factor and the Self-Discipline factor are significantly correlated with subjective sleep disturbances. The first with all items of sleep (initial insomnia - 355, intermediate insomnia - 164, terminal insomnia - 236, total hours of sleep -, 129 and perceived loss -, 289) and the second with three of the items of sleep (sleep 1 - initial insomnia - 163, sleep 3 - terminal insomnia -, 152 and sleep 5 - Perceived loss -, 183). Only Personal Competence proved to be a negative predictor of subjective sleep disturbances. Gender differences in resilience and sleep were also analyzed and no statistically significant differences were found. Conclusions: The Personal Competence and Self-Discipline factors will play an important role in the prevention of sleep problems. .

The architecture of healthy sleep rests upon a network of several interacting neurochemical systems, an arrangement that is easily disrupted by the experience of traumatic stress. As a result, sleep may be among the most susceptible of behaviors to have a negative impact as a result of trauma. Sleep disturbances, or “parasomnias,” such as nightmares, sleepwalking, and insomnia are one of the most prominent hallmarks of PTSD, and the study of these sleep-specific symptoms can provide a window into the underlying pathology of the disorder. The current chapter reviews the preclinical animal literature that has informed our understanding of the brain structures that are involved in the development of these parasomnias. In reviewing adult and child studies of disrupted sleep in PTSD, a distinction is made between the subjective and objective assessment of sleep quality, with a call made for an emphasis on objective measurements in future research.
