COVID-19 pandemic raised concerns about the effects of stress on mental health and sleep deficiency. Cognitive behavioural therapy for insomnia (CBT-I) has been shown to improve sleep quality and insomnia severity, as well as anxiety and depression, and may be protective during times of stress, including the COVID-19 pandemic. The aim of this study was to examine changes in sleep, sleep-related cognitions, stress, anxiety, and depression among people with heart failure (HF). This study was a randomised controlled trial of the effects of CBT-I compared with HF self-management education (attention-control condition), the “HeartSleep Study.” Results showed that improvements in insomnia severity, sleep quality, latency, and efficiency, sleep-related cognitions and stress, anxiety, and depression after participation in CBT-I or an HF self-management class were sustained during the pandemic. Authors conclude that their findings confirm the clinical benefits of CBT-I for people with HF and comorbidities and also suggest the potential benefits of HF self-management education.
Abstract
BACKGROUND The COVID-19 pandemic raised concerns about the effects of stress on sleep and mental health, particularly among people with chronic conditions, including people with heart failure (HF). OBJECTIVE The aim of this study was to examine changes in sleep, sleep-related cognitions, stress, anxiety, and depression among people with HF who participated in a randomized controlled trial of cognitive behavioral therapy for insomnia before the COVID-19 pandemic. METHODS Participants self-reported sleep characteristics, symptoms, mood, and stress at baseline, 6 months after cognitive behavioral therapy for insomnia or HF self-management education (attention control), and during the pandemic. RESULTS The sample included 112 participants (mean age, 63 ± 12.9 years; 47% women; 13% Black; 68% New York Heart Association class II or III). Statistically significant improvements in sleep, stress, mood, and symptoms that occurred 6 months post treatment were sustained during the pandemic. CONCLUSIONS Improving sleep and symptoms among people with HF may improve coping during stressful events, and cognitive behavioral therapy for insomnia may be protective.

Severe mental and physical fatigue in shift work occupations is widespread, and workplace fatigue impacts a great majority of the Emergency Medical Services (EMS) clinician first responders. The hypothesis of this study was that education and training focused on sleep health and fatigue, delivered in an asynchronous manner and tailored to EMS shift workers, would result in improvements in sleep quality and a reduction in self-reported fatigue after a 3-month study interval. This study was a cluster-randomised, 2-arm randomised trial with a wait-list control group. EMS agencies (clusters) were randomised to either the intervention group or a wait-list control group. Results showed that intention-to-treat analyses revealed no differences in measures of sleep quality or fatigue at 3 months or 6 months follow-up. Per protocol analyses showed that the greater the number of education modules viewed, the greater the improvement in sleep quality and the greater the reduction in fatigue at 3-month follow-up. Authors conclude that the findings of this study may be useful to EMS administrators when designing fatigue risk management programmes.
Abstract
BACKGROUND Greater than half of emergency medical services (EMS) clinician shift workers report poor sleep, fatigue, and inadequate recovery between shifts. We hypothesized that EMS clinicians randomized to receive tailored sleep health education would have improved sleep quality and less fatigue compared to wait-list controls after 3 months. METHODS We used a cluster-randomized, 2-arm, wait-list control study design (clinicaltrials.gov identifier: NCT04218279). Recruitment of EMS agencies (clusters) was nationwide. Our study was powered at 88% to detect a 0.4 standard deviation difference in sleep quality with 20 agencies per arm and a minimum of 10 individuals per agency. The primary outcome was measured using the Pittsburgh Sleep Quality Index (PSQI) at 3-month follow-up. Our intervention was accessible in an online, asynchronous format and comprised of 10 brief education modules that address fatigue mitigation topics prescribed by the American College of Occupational Environmental Medicine. RESULTS In total, 36 EMS agencies and 678 individuals enrolled. Attrition at 3 months did not differ by study group (Intervention = 17.4% vs. Wait-list control = 18.2%; p = .37). Intention-to-treat analyses detected no differences in PSQI and fatigue scores at 3 months. Per protocol analyses showed the greater the number of education modules viewed, the greater the improvement in sleep quality and the greater the reduction in fatigue (p < .05). CONCLUSIONS While intention-to-treat analyses revealed no differences in sleep quality or fatigue at 3 months, per protocol findings identified select groups of EMS clinician shift workers who may benefit from sleep health education. Our findings may inform fatigue risk management programs.

Adequate sleep is essential for physical and mental health and wellbeing. This randomised cross-over study of 20 healthy men compared the effects of sleep restriction (sleeping 5 instead of 8 hours) and sleep fragmentation (being woken hourly during the 8-hour sleeping time) on heart rate (HR) and heart rate variability (HRV), both markers of the sympathetic (“fight or flight”) and parasympathetic (“rest and digest”) arms of the autonomic nervous system. Sleep restriction increased HR and decreased HRV, suggesting increased sympathetic and decreased parasympathetic activation. This affected the lighter sleep phases in particular. Sleep fragmentation, on the other hand, did not affect HR or HRV compared to baseline. The authors conclude that sleep restriction may cause more stress than sleep fragmentation.
Abstract
We developed a cross-over study design with two interventions in randomized order to compare the effects of sleep fragmentation and partial sleep restriction on cardiac autonomic tone. Twenty male subjects (40.6 ± 7.5 years old) underwent overnight polysomnography during 2 weeks, each week containing one undisturbed baseline night, one intervention night (either sleep restriction with 5 h of sleep or sleep fragmentation with awakening every hour) and two undisturbed recovery nights. Parameters of heart rate variability (HRV) were used to assess cardiac autonomic modulation during the nights. Sleep restriction showed significant higher heart rate (p = 0.018) and lower HRV-pNN50 (p = 0.012) during sleep stage N1 and lower HRV-SDNN (p = 0.009) during wakefulness compared to the respective baseline. For HR and SDNN there were recovery effects. There was no significant difference comparing fragmentation night and its baseline. Comparing both intervention nights, sleep restriction had lower HRV high frequency (HF) components in stage N1 (p = 0.018) and stage N2 (p = 0.012), lower HRV low frequency (LF) (p = 0.007) regarding the entire night and lower SDNN (p = 0.033) during WASO during sleep. Sleep restriction increases sympathetic tone and decreases vagal tone during night causing increased autonomic stress, while fragmented sleep does not affect cardiac autonomic parameters in our sample.

Plain language summary
While inadequate or poor-quality sleep has been associated with a wide range of adverse physical and psychological health outcomes in infants, children and adolescents, interest is growing regarding the association of sleep with more global indices of health, such as health-related quality of life (HRQOL). The aim of this study was to determine the effect of mild sleep deprivation on HRQOL in children without major sleep issues. This study was a secondary analysis based on the DREAM randomised crossover trial. Children were randomised to one of two groups (sleep restriction or sleep extension) with a 1-week washout in between. Bedtimes were manipulated to be 1 hour later (sleep restriction) and 1 hour earlier (sleep extension) than usual for 1 week each. Wake times were unchanged. Results showed that after only 1 week of receiving 39 minutes less sleep per night between sleep conditions, children reported significantly lower HRQOL in terms of their physical and overall well-being and ability to cope well at school. Authors conclude that ensuring children receive sufficient good-quality sleep is an important child health issue.
Abstract
IMPORTANCE Little is known regarding the effect of poor sleep on health-related quality of life (HRQOL) in healthy children. OBJECTIVE To determine the effect of induced mild sleep deprivation on HRQOL in children without major sleep issues. DESIGN, SETTING, AND PARTICIPANTS This prespecified secondary analysis focused on HRQOL, a secondary outcome of the Daily Rest, Eating, and Activity Monitoring (DREAM) randomized crossover trial of children who underwent alternating weeks of sleep restriction and sleep extension and a 1-week washout in between. The DREAM trial intervention was administered at participants' homes between October 2018 and March 2020. Participants were 100 children aged 8 to 12 years who lived in Dunedin, New Zealand; had no underlying medical conditions; and had parent- or guardian-reported normal sleep (8-11 hours/night). Data were analyzed between July 4 and September 1, 2022. INTERVENTIONS Bedtimes were manipulated to be 1 hour later (sleep restriction) and 1 hour earlier (sleep extension) than usual for 1 week each. Wake times were unchanged. MAIN OUTCOMES AND MEASURES All outcome measures were assessed during both intervention weeks. Sleep timing and duration were assessed using 7-night actigraphy. Children and parents rated the child's sleep disturbances (night) and impairment (day) using the 8-item Pediatric Sleep Disturbance and 8-item Sleep-Related Impairment scales of the Patient-Reported Outcomes Measurement Information System questionnaire. Child-reported HRQOL was assessed using the 27-item KIDSCREEN questionnaire with 5 subscale scores and a total score. Both questionnaires assessed the past 7 days at the end of each intervention week. Data were presented as mean differences and 95% CIs between the sleep restriction and extension weeks and were analyzed using intention to treat and an a priori difference in sleep of at least 30 minutes per night. RESULTS The final sample comprised 100 children (52 girls [52%]; mean [SD] age, 10.3 [1.4] years). During the sleep restriction week, children went to sleep 64 (95% CI, 58-70) minutes later, and sleep offset (wake time) was 18 (95% CI, 13-24) minutes later, meaning that children received 39 (95% CI, 32-46) minutes less of total sleep per night compared with the sleep extension week in which the total sleep time was 71 (95% CI, 64-78) minutes less in the per-protocol sample analysis. Both parents and children reported significantly less sleep disturbance at night but greater sleep impairment during the day with sleep restriction. Significant standardized reductions in physical well-being (standardized mean difference [SMD], -0.28; 95% CI, -0.49 to -0.08), coping in a school environment (SMD, -0.26; 95% CI, -0.42 to -0.09), and total HRQOL score (SMD, -0.21; 95% CI, -0.34 to -0.08) were reported by children during sleep restriction, with an additional reduction in social and peer support (SMD, -0.24; 95% CI, -0.47 to -0.01) in the per-protocol sample analysis. CONCLUSIONS AND RELEVANCE Results of this secondary analysis of the DREAM trial indicated that even 39 minutes less of sleep per night for 1 week significantly reduced several facets of HRQOL in children. This finding shows that ensuring children receive sufficient good-quality sleep is an important child health issue.

Plain language summary
Sleep disturbance is a universal experience during the pregnancy and postpartum periods. Sleep disturbance is linked to a range of negative consequences. Literature shows that cognitive behavioural Therapy for Insomnia (CBT-I) is an effective treatment, with comparable short-term and superior long-term effects to sleep medication alone. The aim of this study was to evaluate the short-, medium-, and long-term efficacy of a non-pharmacological sleep intervention in the perinatal periods. The study was a longitudinal randomised controlled trial based on the SEED (Sleep Eat Emotions and Development) project which was a two-arm, parallel-group, single-blind, superiority randomised controlled trial. Participants were pregnant women enrolled in Childbirth Education and were randomised 1:1 to the intervention or a comparison condition. Results showed that compared to receiving an attention- and time-matched control, receiving a cognitive behavioural sleep intervention was associated with lower symptoms of insomnia, sleep disturbance, and sleep-related impairment during late pregnancy. Moreover, the intervention had long-term benefits to gestational parents’ sleep at 2-year postpartum. Authors conclude that a scalable cognitive behavioural sleep intervention, tailored for the perinatal periods, is feasible, acceptable, and efficacious in buffering against the natural increase in sleep complaints during the 3rd trimester.
Abstract
BACKGROUND Sleep disturbance is common in gestational parents during pregnancy and postpartum periods. This study evaluated the feasibility and efficacy of a scalable cognitive behavioural therapy (CBT) sleep intervention tailored for these periods. METHODS This is a two-arm, parallel-group, single-blind, superiority randomised controlled trial. Nulliparous females without severe medical/psychiatric conditions were randomised 1:1 to CBT or attention- and time-matched control. All participants received a 1 h telephone session and automated multimedia emails from the third trimester until 6 months postpartum. Outcomes were assessed with validated instruments at gestation weeks 30 (baseline) and 35 (pregnancy endpoint), and postpartum months 1.5, 3, 6 (postpartum endpoint), 12 and 24. RESULTS In total, 163 eligible participants (age M ± s.d. = 33.35 ± 3.42) were randomised. The CBT intervention was well accepted, with no reported adverse effect. Intention-to-treat analyses showed that compared to control, receiving CBT was associated with lower insomnia severity and sleep disturbance (two primary outcomes), and lower sleep-related impairment at the pregnancy endpoint (p values ⩽ 0.001), as well as at 24 months postpartum (p ranges 0.012-0.052). Group differences across the first postpartum year were non-significant. Participants with elevated insomnia symptoms at baseline benefitted substantially more from CBT (v. control), including having significantly lower insomnia symptoms throughout the first postpartum year. Group differences in symptoms of depression or anxiety were non-significant. CONCLUSIONS A scalable CBT sleep intervention is efficacious in buffering against sleep disturbance during pregnancy and benefitted sleep at 2-year postpartum, especially for individuals with insomnia symptoms during pregnancy. The intervention holds promise for implementation into routine perinatal care.

Up to 80% of gastroesophageal reflux disease (GORD) patients experience symptoms during the night, such as heartburn and regurgitation, which can have a profound negative impact on sleep quality and daytime functioning. The aim of this study was to evaluate the effect of sleep positional therapy, using a novel electronic sleep positional therapy wearable device, on sleep position and on nocturnal gastroesophageal reflux symptoms. This study was a single-centre, double-blind, randomised, sham-controlled trial in 100 patients with nocturnal gastroesophageal reflux symptoms. Patients were randomised to one of the two groups (intervention or sham group), and analysed according to the intention-to-treat approach. Results showed that treatment with an electronic sleep positional–wearable device led to an increase in time spent sleeping in the left lateral decubitus position and effectively alleviated nocturnal reflux symptoms compared with sham treatment. Authors conclude that positional therapy can be a valuable addition to other therapeutic strategies in GORD.
Abstract
BACKGROUND & AIMS Experimental studies have suggested that sleep position plays a role in the occurrence of nocturnal gastroesophageal reflux and the left lateral decubitus position is most favorable. The aim of this study was to evaluate the effect of a novel electronic sleep positional therapy wearable device on sleep position and nocturnal reflux symptoms. METHODS We performed a double-blind, randomized, sham-controlled trial in patients with nocturnal symptoms of gastroesophageal reflux. Patients were advised to sleep in the left lateral decubitus position and were assigned randomly (1:1) to an electronic sleep positional therapy wearable device, programmed to either produce a vibration when in the right lateral position (intervention) or only during the first 20 minutes (sham). The primary outcome was treatment success, defined as a 50% or more reduction in the nocturnal reflux score. Secondary outcomes included change in sleep position and reflux symptoms. RESULTS One hundred patients were randomized. In the intention-to-treat analysis, the rate of treatment success was 44% in the intervention group (22 of 50) vs 24% in the sham group (12 of 50) (risk difference, 20%; 95% CI, 1.8%-38.2%; P = .03). Treatment led to a significant avoidance of sleeping in the right lateral decubitus position (intervention 2.2% vs sham 23.5%; P = .000) and increased time sleeping in the left lateral decubitus position (intervention 60.9% vs sham 38.5%; P = .000). More reflux-free nights were observed in the intervention group (intervention 9 nights [interquartile range, 6-11 nights] vs sham 6 nights [interquartile range, 3-9 nights]; P = .01). CONCLUSIONS Sleep positional therapy using an electronic wearable device promotes sleeping in the left lateral decubitus position and effectively alleviates nocturnal reflux symptoms compared with sham treatment (https://www.trialregister.nl, NL8655).

Plain language summary
The “sleep effect” refers to the ability of sleep to enhance the recall of memories. However, for a long time, sleep and memory have been investigated without considering the possible contribution of emotional experience. The aim of this study was to investigate the separate roles of sleep and wakefulness on emotional memory consolidation. This study was a randomised controlled trial where participants (n = 40) were randomly assigned to a Sleep First Group (SF; males n = 8, females n = 12) or a Wake First Group (WF; males n = 9, females n = 11), which provided for two different experimental conditions. The two groups underwent the encoding phase of an emotional images task with negative and neutral pictures at either 09:00 hours (WF) or 21:00 hours (SF). Results showed: - a clear beneficial role of post-learning sleep compared with post-learning wakefulness on memory consolidation. However, this beneficial effect of sleep was not specific to negative pictures. Negative stimuli were better remembered in both conditions, compared with neutral images. - that 24 hours after the encoding, performance decreased in the SF, who spent the previous 12 hours awake, but not in the WF, who had a night of sleep in the previous 12 hour. - a positive association between memory performance for negative items at the immediate test and REM% the night before the encoding. Authors conclude that sleep does not seem to preferentially improve emotional memory, although it may affect the encoding of negative information.
Abstract
Sleep has a beneficial effect on memory consolidation. However, its role in emotional memory is currently debated. Here, we investigate the role of sleep and a similar period of wakefulness on the recognition of emotional pictures and subjective emotional reactivity. Forty participants without any major physical, neurological or psychological condition were randomly assigned to the Sleep First Group or Wake First Group. The two groups underwent the encoding phase of an emotional images task with negative and neutral pictures at either 09:00 hours (Wake First Group) or 21:00 hours (Sleep First Group). Then participants performed an immediate recognition test (T1), and two delayed tests 12 hr (T2) and 24 hr (T3) later. Perceived arousal and valence levels were collected for each picture. Sleep parameters were recorded at participants' homes with a portable device. No differences were observed at T1, whereas at T2 the Sleep First Group showed a higher memory performance than the Wake First Group. At T3, performance decreased in the Sleep First Group (who spent the previous 12 hr awake), but not in the Wake First Group (who slept during the previous 12 hr). Overall, negative images were remembered better than neutral ones. We also observed a positive association between memory performance for negative items at the immediate test and the percentage of rapid eye movement sleep the night before the encoding. Our data confirm that negative information is remembered better over time than neutral information, and that sleep benefits the retention of declarative information. However, sleep seems not to preferentially improve emotional memory, although it may affect the encoding of negative information.

Women who have completed treatment for cancer experience physical and psychological sequelae that can negatively affect their quality of life (QoL) and health as they recover from treatment. The aim of this study was to examine the association between sleep problems and health related QoL. This study was a single-blinded, multi-centre randomised controlled trial. In total, 175 participants were randomised to the intervention group and 176 were randomised to the usual care (control) group. Results showed that: - sleep outcomes did not predict mental HRQoL after adjustment for covariates. - sleep duration did not predict physical or mental HRQoL after adjustment. - participants in the intervention group did not show greater long-term adherence to sleep recommendations (i.e. sleeping>7 h). Authors conclude that there was no significant effect of the intervention on the sleep duration outcome or any of the other sleep outcomes measured. Thus, opportunities to optimise and better target sleep interventions should continue to be explored in this population.
Abstract
PURPOSE Sleep disturbance after cancer treatment could compromise recovery. This paper examined the associations between post-treatment sleep problems and health-related quality of life (HRQoL), and the effectiveness of an e-enabled lifestyle intervention on sleep outcomes. METHODS The Women's Wellness after Cancer Program (WWACP) was examined in a single blinded, multi-centre randomised controlled trial. Data were collected from 351 women (Mage = 53.2, SD = 8.8; intervention n = 175, control group n = 176) who had completed surgery, chemotherapy and/or radiotherapy for breast, gynaecological or blood cancers within the previous 24 months. Participants completed the Pittsburgh Sleep Quality Index (PSQI) at baseline (prior to intervention randomisation), and at 12 and 24 weeks later. Sociodemographic information, menopausal symptoms (Greene Climacteric Scale) and HRQoL (36-Item Short Form Health Survey; SF-36) were also collected. Linear panel regression was used to examine the association between sleep variables and SF36 Physical Component Summary (PCS) and Mental Component Summary (MCS) scores. A difference-in-difference regression model approach was used to examine the intervention effect on the sleep outcomes. RESULTS After adjustment for potential confounders, the sleep variables (except sleep duration) significantly predicted physical, but not mental, HRQoL. There was no statistically significant effect of the intervention on sleep outcomes at 12 or 24 weeks. CONCLUSION Women who have completed treatment for cancer experience sleep problems that are associated with decreased physical HRQoL. Improving sleep through targeted interventions should improve their physical HRQoL. Improved targeting of the sleep components of the WWACP should be explored.

Sleep is a crucial factor in healthy aging. Good sleep may enhance cognition, mental health, ability to engage in activities, self-reported health and reduce fragility. Aging is associated with declines in most physiological systems that culminate in sleep changes and limited physical function. The aim of this study was to investigate the effects of multi-component exercise (MCE) on sleep quality and physical fitness among middle-aged adults. This study was a randomised controlled trial with a quasi-experimental design. The participants were randomly assigned to either the multi-component exercise or the control group. Results showed that a 12-week MCE program was effective in improving sleep quality (global sleep quality, sleep disturbances, and sleep efficiency) and flexibility and preventing a decline of muscular strength in middle-aged adults. Authors conclude that their findings provide support for the multi-component exercise training as a new strategy for health promotion in this population.
Abstract
Sleep is a crucial factor in healthy aging. However, most middle-aged adults experience high levels of sleep disorders. While previous findings have suggested exercise training could benefit the quality of sleep, the effects of multi-component exercise on sleep quality are less examined. Accordingly, the current study aimed to assess the effectiveness of a multi-component exercise program on the quality of sleep among middle-aged adults. Twenty-four middle-aged adults were randomly assigned either to a multi-component exercise (MCE) group or a control group. The participants in the MCE group attended a 90-min session per week for 12 weeks. The control group was instructed to maintain their daily routine for 12 weeks. The primary outcome was the sleep quality evaluated by the Pittsburgh Sleep Quality Index (PSQI). The secondary outcome was physical fitness, including muscular strength and endurance, balance, and flexibility. Regarding sleep quality, the global mean score (p = 028), sleep disturbances (p = 011), and sleep efficiency (p = 035) of the PSQI scores were significantly reduced in the MCE group after the 12-week intervention. Regarding physical fitness, the flexibility of the MCE group improved significantly after the intervention (p = 028), yet, no significant change was observed in the control group. Additionally, the muscular strength of the control group declined significantly after the 12-week period (p = 034). Our results revealed the effectiveness of the MCE intervention in improving sleep quality and physical fitness in middle-aged adults. Further studies using larger sample sizes, objective measures of sleep quality, different types of exercise training, as well as different populations, are warranted to extend our current findings.

Obstructive sleep apnoea (OSA) is a condition characterised by complete or partial obstruction of the upper airway during sleep, resulting in oxygen desaturation or arousal from sleep. The aim of this study was to develop, implement and assess the efficacy of a patient-centred sleep study report (PCSR) within the sleep laboratory of a tertiary referral hospital. This study was performed in two phases. The first phase involved the development and critical appraisal of the PCSR. The second phase was a prospective, randomised controlled trial. Patients were randomised to receive the PCSR or standard care. Results showed that the development and implementation of a PCSR was feasible and improved patient understanding and perceived patient-physician interaction in patients with moderate to severe OSA. Authors conclude that longer term analysis and an increased sample size is needed to determine whether these findings can be translated to patients with a milder degree of OSA.
Abstract
PURPOSE Obstructive sleep apnoea (OSA) is a common condition with a range of short- and long-term health implications. Providing patient-centred care is a key principle to ensure patients are well informed and empowered to participate in clinical decision making. This study aimed to develop a patient-centred sleep study report for patients with obstructive sleep apnoea and to determine whether or not its implementation led to improved patient understanding of their disease. METHODS The study was performed in two phases. The first phase utilised the Delphi-survey technique to develop and critically appraise a patient-centred sleep study report (PCSR) for patients with OSA, to accurately and simply convey key components of the patient's diagnosis and management. The second phase was a prospective, randomised controlled trial to assess the effect of the PCSR on patient knowledge, self-efficacy, and understanding as measured through validated patient questionnaires. RESULTS The PCSR was developed on key concepts deemed to be important by the surveyed physicians, senior sleep scientists and patients. This included ensuring the results were customised, highlighting the patient's apnoea-hypopnea index, oxygen desaturation index and arousal index and limiting technical information to a few key pieces. Patients randomised to receive the PCSR had improved understanding and perceived patient-physician interaction compared to those randomised to standard care. CONCLUSION The development and implementation of the PCSR was feasible and improved patient understanding and perceived patient-physician interaction in patients with moderate to severe OSA. Whether or not use of the PCSR will translate to improved compliance with therapy will require further evaluation.
