Abstract:

ABSTRACT Sleep disorders have become very common in today's world. The various sleep related disorders are increasing at an alarming proportion. The first sleep clinics in the United States were established in the 1970s by interested doctors and technicians; sleep centers are specialized centers where an individual is provided home like environment and surroundings and his sleep cycle is monitored. Active therapeutic and diagnostic interventions are also done here. This article discusses various planning and designing issues of sleep center.

Abstract:

Abstract We assessed the effect of a daytime sleep opportunity on planning and risk-related decision-making in emerging adults using multiple neurobehavioral assessments. A total of 136 healthy emerging adults (20.0 ± 1.5 years), 65% female, performed the Risky-Gains Task and the Tower of London test twice. Between these assessments, they were randomized to either have a sleep opportunity monitored by polysomnography (Sleep group, n = 101) or to stay awake (Wake group, n = 35). During Test 2, in comparison to the Sleep group, the Wake group showed increased sleepiness, worse planning ability and more decrease in reaction times when selecting risky choices. Changes in Tower of London test steps used and Risky-Gains Task response time correlated with the number of central and frontal fast sleep spindles, respectively. These results indicate that among emerging adults who commonly have poor sleep patterns, a daytime sleep opportunity was related to better planning ability, better psychomotor vigilance and stable response speeds in risk-related decision-making. Changes in planning and risk-related decision-making correlated with the number of sleep spindles during the nap, supporting a specific role for sleep in modulating planning and potentially other higher-order cognitive functions.

Abstract:

The prefrontal cortex (PFC) consists of the cortex lying in front of the primary and secondary motor cortex, and includes the dorsolateral and orbital areas, frontal eye fields, and Broca's area. Not all of the functions of the PFC are known, but key ones are the maintenance of wakefulness and non-specific arousal, and the recruiting of various cortical areas required to deal with tasks in hand (Luria, 1973; Stuss & Benson, 1986; Fuster, 1989). Other roles include (Kolb & Whishaw, 1985) planning, sensory comparisons, discrimination, decisions for action, direction and maintenance of attention at a specific task, execution of associated scanning eye movements, and initiation and production of novel goal-directed behaviour (especially with speech). Of the senses, vision makes a particular demand of the PFC, and this is reflected by the frontal eye fields.

Abstract:

Objective: Hand washing and sleep hygiene are two important health behaviors. The purpose of the current study was to identify the motivational and volitional antecedents of college students’ hand washing and sleep hygiene behaviors based on an integrated model of behavior that combined social-cognition constructs from the Theory of Planned Behavior (TPB) and Health Action Process Approach (HAPA). Methods: Using a prospective design, college students (N = 1106) completed a survey assessing the motivational constructs of action self-efficacy, attitudes, subjective norm, perceived behavioral control, intentions, and behaviors of hand washing and sleep hygiene at Time 1. Demographic variables were also collected. One month later, at Time 2, college students (N = 524) self-reported on their volitional factors of maintenance self-efficacy, action planning, coping planning, and behaviors of hand washing and sleep hygiene. A further 2 months later, at Time 3, college students (N = 297) were asked to self-report on their hand washing and sleep hygiene behaviors over the past month. Findings: Data were analyzed using variance-based structural equation modelling. Results showed significant direct effects of attitudes, subjective norm, and perceived behavioral control on intentions; significant direct effects of action self-efficacy on maintenance self-efficacy; and significant direct effects of maintenance self-efficacy on action planning and coping planning. Significant direct effects of intention on action planning (sleep hygiene only), and significant direct effects of intention, maintenance self-efficacy (hand washing only), action and coping planning on behavior were also observed. Action planning also moderated the intention–behavior relationship, but only for hand washing. There were also significant total indirect effects of action self-efficacy on behavior mediated by maintenance self-efficacy, action planning, and coping planning for both behaviors, and significant total indirect effects of subjective norm and perceived behavioral control on behavior mediated by intention for sleep hygiene. When past behavior was included in the integrated model predicting all the psychological variables and behavior, all of the structural relations were attenuated. Discussion: Current findings indicate that college students’ hand washing and sleep hygiene behaviors are a function of both motivational and volitional factors. Findings also indicate that the TPB and HAPA pathways might differ for the two health behaviors. Implications of the current findings for future health interventions aimed at improving college students’ hand washing and sleep hygiene are discussed.

Abstract:

Sleep disordered breathing describes an important group of conditions that causes abnormal nocturnal gas exchange, with important implications in the peri-operative management plan. An understanding of the pathophysiology behind obstructive sleep apnoea and other disorders that may lead to hypoventilation can help to prevent complications. Patients with these disorders may be minimally symptomatic and it requires careful screening in the pre-operative assessment process for a diagnosis to be made. Decisions regarding initiation of therapy, such as positive airway pressure, and delay of the operation need to be carefully weighed up against the urgency of the surgical intervention. Planning of the peri-operative care, including the use of positive airway pressure therapy and appropriate post-operative monitoring, can help to avoid respiratory and cardiovascular morbidities and improve clinical outcomes.Educational aimsTo review different types of sleep disordered breathing and available screening methods in pre-operative assessment.To understand the pathophysiology behind sleep disordered breathing and how it can lead to complications in the peri-operative setting.To review the planning and treatment strategies that should be considered as part of peri-operative management.

Abstract:

ABSTRACT Introduction: The aging process causes changes in the sleep-wake cycle and cognition, especially executive functions. Interventions are required to minimize the impact of the losses caused by the aging process. Objective: To evaluate the effects of a cognitive training program and psychoeducation on sleep hygiene techniques for executive functions and sleep quality in healthy elderly. Methods: The participants were 41 healthy elderly randomized into four groups ([CG] control group, cognitive training group [CTG], sleep hygiene group [SHG] and cognitive training and hygiene group [THG]). The study was conducted in three stages: 1st - assessment of cognition and sleep; 2nd - specific intervention for each group; 3rd - post-intervention assessment. Results: The results showed that the CTG had significant improvements in cognitive flexibility tasks, planning, verbal fluency and episodic memory, gains in sleep quality and decreased excessive daytime sleepiness. The SHG also had improved sleep quality, excessive daytime sleepiness and significant improvements in insights, planning, attention and episodic memory. The THG had significant gains in cognitive flexibility, problem solving, verbal fluency, attention and episodic memory. Conclusion: Cognitive training and sleep hygiene interventions were useful strategies for improving cognitive performance and sleep quality of healthy elderly, but there was no evidence that sessions combining cognitive training and psychoeducation on sleep hygiene enhanced the gains provided by these interventions applied individually.

Abstract:

The sleep sets technique is a path-dependent pruning method for state space search. In the past, the combination of sleep sets with graph search algorithms that perform duplicate elimination has often shown to be error-prone. In this paper, we provide the theoretical basis for the integration of sleep sets with common search algorithms in AI that perform duplicate elimination. Specifically, we investigate approaches to safely integrate sleep sets with optimal (best-first) search algorithms. Based on this theory, we provide an initial step towards integrating sleep sets within A* and additional state pruning techniques like strong stubborn sets. Our experiments show slight, yet consistent improvements on the number of generated search nodes across a large number of standard domains from the international planning competitions.

Abstract:

Sleep plays an important role in both students’ academic and personal life. Despite widespread sleep problems among young adults, few studies focus on higher education students living in campus residence. This study investigated residence-living students’ sleep patterns, sleep promoting practices, sources of help seeking, and preferred ways to receive information. Results highlighted that 66.8% of the participants did not think they had enough sleep. However, only 18.9% of the students sought help. The campus residence sleep environment was challenging for many students. Problems such as uncomfortable room temperature and noise were frequently identified. Students used different strategies to promote sleep such as opening the window, reading books, listening to music, and alcohol. Efficient knowledge translation activities to facilitate the understanding of sleep physiology and sleep problem solving are needed at both the student and the organizational planning/administration level. Further studies focusing specifically on sleep environment scans and developing guidelines are recommended.

Abstract:

Abstract Introduction Evening chronotypes tend to have reduced white matter integrity within their axonal tracts and reduced functional connectivity compared to morning types, a pattern that has been attributed to chronic “social jet lag” and its attendant disrupted sleep patterns. It is not clear whether brain differences are due to chronotype, total sleep time (TST), or whether they are associated with actual bedtime exclusive of these other factors. Here we examined morphometric gray matter volume (GMV) and its correlation with bedtime, after controlling for confounding factors. Methods Forty-five healthy adults (22 female; aged 20 to 43), completed the Horne-Ostberg Morningness-Eveningness Questionnaire (MEQ) and the Tower of London (TOL), an executive function task of planning and sequencing. Participants wore an actigraph for 7 days and completed structural MRI imaging during the period of actigraphy. Morphometric GMV data were processed using standard procedures in SPM12. After controlling for age, sex, and intracranial volume, actigraphic bedtime was entered into a regression analysis to predict orbitofrontal GMV. Regional GMV was extracted and correlated with TOL performance. Effects of TST and MEQ were also examined during regression. Results Later bedtime was associated with increased GMV in the left superior orbitofrontal gyrus (p=.044, FWE corrected). This association remained significant after controlling for TST and MEQ. Moreover, greater GMV in this cluster was associated with poorer planning and sequencing on TOL in terms of excess moves (r=.357, p=.017), and faster response times (r=-.356, p=.018), suggesting impulsivity. Conclusion Later bedtime was associated with greater GMV of the orbitofrontal cortex, even after controlling for TST and chronotype, and this pattern was associated with greater impulsiveness and poorer planning. The causal direction of the relationship between bedtime and executive deficits remains unclear and will require further research. However, it is clear that sleep patterns, brain structure, and behavior are intimately related. Support Defense Advanced Research Projects Agency Young Faculty Award: DARPA-12-12-11-YFA11-FP-029

Abstract:

Subjective sleep quality has been recognized as a valuable indicator of health and quality of life. This exploratory and descriptive study aimed at describing habitual sleep quality of women suffering from gynecological and breast cancer and comparing habitual versus sleep quality during hospitalization. Twenty-five women admitted in hospital for clinical treatment of cancer completed the Pittsburgh Sleep Quality Index (PSQI) within 72 hours after admission and again just before discharge. Fifty-two percent of subjects reported habitual bad sleep quality, and this proportion increased to 80% of subjects during hospital stay. Subjects indicated the following most frequent causes of night sleep disturbance: need to go to the toilet, waking up early and receiving nursing care during the night. Results point to the importance of including careful assessment of sleep quality and environment in nursing care planning for oncology patients, mainly during hospitalization.

Abstract:

Insomnia is perhaps the most common type of sleep disorder in the family medicine population. It is best described as a persistent difficulty initiating or maintaining sleep, or a report of non-restorative sleep, accompanied by related daytime impairment. There is increasing evidence of a strong association between insomnia and various medical and psychiatric comorbidities. Diagnosis of insomnia and treatment planning rely on a thorough sleep history to address contributing and precipitating factors as well as maladaptive behaviours resulting in poor sleep. Cognitive behavioural therapy for insomnia (CBT-I) is the mainstay of treatment and is a safe and effective approach. The key challenge of CBT-I is the lack of clinicians to implement it. The newer generation nonbenzodiazepines (e.g. zolpidem) are used as first-line pharmacotherapy for chronic insomnia. Newer drugs active on targets other than the gamma-aminobutyric acid receptor are now available, but clear treatment guidelines are needed.

Abstract:

Objective This study aimed to assess the sleep quality and the factors affecting the sleep quality in patients with systemic lupus erythematosus (SLE). Methods This was a descriptive and cross-sectional study conducted in 105 patients with SLE who were admitted to the rheumatology polyclinic of a university hospital between May and July 2017. The data were collected using a “Patient Description Form” and the “Pittsburgh Sleep Quality Index (PSQI).” Results The total mean (standard deviation) PSQI score of the patients was 7.81 (3.11). Duration of disease, presence of comorbid diseases, side effects of drugs, and sleep disruption and related problems were identified as factors affecting sleep quality. The model of the regression showed that side effects of drugs, sleep disruption, and trouble falling asleep suffered higher PSQI score (bad sleep quality). Conclusions Results of this study showed that the sleep quality was generally poor in patients with SLE. Sleep quality was affected by some disease and sleep variables. Therefore, comprehensive sleep evaluation is necessary in the planning of treatment and care of SLE patients and to implement initiatives to improve sleep patterns in these patients.

Abstract:

Background: poor sleep is common in MS and it contributes to fatigue. The β interferons produce systemic effects which may not adapt and may induce fatigue. Objective: to verify whether subjective poor sleep and fatigue during chronic therapy correspond to reduced sleep efficiency obtained by actigraphy at home. Methods: 42 ambulatory relapsing remitting MS patients with mild disability were monitored for at least 7 nights. Habitual sleep quality and fatigue were assessed with the MOS sleep measure and the Fatigue Severity Scale. Sleep logs provided daily sleep quality assessments during actigraphy at home. Patients were grouped according to their current treatment: no therapy, glatiramer acetate, IFNβ 3 times a week, and IFNβ once a week. Results and Conclusion: sleep efficiency was reduced by an average of 5% in 2/3 of the nights following IFNβ injections compared to the other nights, and daily sleep ratings correlated with actigraphy. Patients on glatiramer acetate also showed a lower sleep efficiency than patients without therapy. Actigraphy data were only modestly correlated with MOSsm scores, not with fatigue. Long term adaptation of sleep effects of immunomodulant agents is incomplete and needs to be considered in treatment planning and assessment of sleep in MS.

Abstract:

Abstract Introduction Structural interventions for obstructive sleep apnea (OSA) have unpredictable success rates. Anatomically accurate computer simulations of airflow and soft tissue dynamics may be used in future virtual intervention planning tools to identify the optimal patient interventions. The objective of this study is to review the existing literature on the correlation between computer-derived biomechanical variables and clinical measures of OSA severity. Methods Scientific papers written in English that correlated the apnea-hypopnea index (AHI) with computer-derived biomechanical variables were identified by searching on the PubMed and SCOPUS databases the search phrase “sleep apnea” AND “computational fluid dynamics” OR "finite element” OR “fluid structure interaction”. Results A total of 19 articles were identified that reported correlations between computer-derived biomechanical variables and AHI, which was the metric of OSA severity reported in most studies. These studies demonstrated that several anatomic and physiologic variables correlate with OSA severity, including airspace cross-sectional areas, airspace volumes, and airflow resistance. No studies were found that correlated computer-derived dynamic measures of upper airway mechanical stability, such as tissue compliance, to OSA severity. Conclusion Computer-derived anatomic and physiologic variables may serve as useful predictors of surgical outcome or mandibular device treatment response in OSA patients. Further research is needed to test the hypothesis that virtual surgery planning based on computer-derived measures of upper airway stability can improve outcomes of OSA interventions.

Abstract:

Purpose Several epidemiological studies have reported an age-related increase in the prevalence of sleep disturbances. This study aims to investigate the relationship between sleep and sarcopenia/frailty in older adults and clarify issues that remain to be addressed in future studies. Design/methodology/approach PubMed was searched for relevant studies with the following keywords in the title: “sleep” and “sarcopenia” or “sleep” and “frailty.” A total of 15 studies published in English between 1998 and 2018 were reviewed. Findings Among the four studies that examined the relationship between sarcopenia and sleep, two reported that long or short sleep duration increased the risk of sarcopenia and this association was more pronounced in women than men. Among the seven studies examining the relationship between frailty and sleep, four reported that higher Pittsburgh Sleep Quality Index (PSQI) scores were associated with an increased risk of frailty. Practical implications Most previous studies have focused on interventions targeting a single area such as muscle strength or exercise habits, in older adults at risk for frailty. The results suggest that interventions targeting improved sleep may positively impact the maintenance of muscle strength. Originality/value The literature review revealed that too much or too little sleep increases the risk of sarcopenia in older adults. Further, sleep deprivation, greater night-time wakefulness and reduced sleep quality increase the risk of frailty. Interestingly, the risk of mortality is increased in individuals with daytime functional disorders such as excessive drowsiness or napping habits.

Abstract:

The coronavirus pandemic and related government restrictions have a significant impact on peoples’ everyday functioning and working, which influences their physical and mental health. The aim of the study was to examine the associations between stress and sleep quality of people of different working modes: working in the workplace (WP), working remotely (RW), and nonworking (NW) in relation to their physical activity (PA) during COVID-19 pandemic lockdown in Poland. It was an online survey performed during governmental lockdown in April 2020. The data were collected form 1959 adults using International Physical Activity Questionnaire—Short Form (IPAQ-SF), Pittsburgh Sleep Quality Index (PSQI), and Perceived Stress Scale (PSS). The conducted analysis included t-Student test, analysis of variance (ANOVA), and mediation analysis (MANOVA). A moderate level of stress was reported in 57% of participants, and 34% of them reported a high stress level. Poor sleep quality was reported in 64% of participants. Total PA performed daily was, on average, 184.8 ± 170.5 min/day for WP, 120.6 ± 124.4 min/day for RW, and 124.6 ± 114.7 min/day for NW (p < 0.001). There was a relationship observed between the stress and sleep quality vs. PA habit and working mode, with p < 0.05. Being physically active can be beneficial to perceive less stress and sleep disturbances influencing sleep quality, especially in remotely or nonworking people. Planning future pandemic restrictions, the policymakers should be aware of the appropriate guidelines of work planning and PA recommendations for people of different working modes.

Abstract:

AbstractAimThe objective of this study was to assess determinants of poor sleep quality which is an under-diagnosed and under-treated problem in elderly patients with diabetes mellitus, hyperlipidemia and hypertension.BackgroundPoor sleep quality is linked to decreased quality of life, increased morbidity and mortality. Poor sleep quality is common in the elderly population with associated cardiometabolic risk factors such as diabetes, hyperlipidemia and hypertension.MethodsThis is a cross-sectional study undertaken in the primary healthcare setting (Singhealth Polyclinics-Outram) in Singapore. Singaporeans aged 65 years and above who had at least one of the three cardiometabolic risk factors (diabetes, hypertension and hyperlipidemia) were identified. Responders’ sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI) questionnaire and were divided into those with good quality sleep and those with poor quality sleep, based on the PSQI score. Information on demographics, co-morbidities and lifestyle practices were collected. Descriptive and multivariate analyses of determinants of poor sleep were determined.FindingsThere were 199 responders (response rate 88.1%). Nocturia (adjusted prevalence rate ratio 1.54, 95% confidence interval 1.06–2.26) was found to be associated with an increased risk of poor sleep quality in elderly patients with diabetes mellitus, hypertension and hyperlipidaemia. Nocturia, a prevalent problem in the Asian elderly population, has been found to be associated with poor sleep quality in our study. Hence, it is imperative to identify and treat patients with nocturia to improve sleep quality among them.

Abstract:

Background/Aims Sleep disturbances are common among children with cerebral palsy, resulting in adverse consequences. Investigating the association between leisure activities and sleep disturbances could help to develop ways to promote their sleep quality. This study primarily aimed to investigate the association between leisure activities and sleep disturbances among children with and without cerebral palsy. The secondary aim was to study the prevalence of sleep disturbances and some of its associated factors. Methods A total of 75 children with cerebral palsy (study group) (mean age 10.0 ± 2.5 years) and 75 typically developing children (control group) (mean age 10.5 ± 2.9 years) were randomly selected to completed the Children's Assessment of Participation and Enjoyment. Sleep disturbances were assessed using the Sleep Disturbance Scale for Children. Factors associated with sleep disturbances (age, gender, school attendance, bedroom sharing, type of cerebral palsy, motor functions, eating and drinking ability and communication functions) were statistically analysed and the prevalence of sleep disturbances was calculated. Results Overall frequency of leisure participation was strongly correlated with overall sleep disturbances (P<0.001) among both groups. The prevalence of overall sleep disturbances was 17.1% and 10.6% among the study and the control groups respectively. Eating and drinking ability and spastic quadriplegia emerged as the strongest predictors of overall negative scores on the Sleep Disturbance Scale for Children. Conclusions Greater participation in leisure activities is associated with better sleep. Occupational therapists are encouraged to consider this association when planning for occupation-based interventions aimed at enhancing occupational performance.

Abstract:

AbstractBackgroundObstructive sleep apnoea occurs consequent to partial or complete upper airway obstruction, caused mostly by the collapse of upper airway musculature. Drug-induced sleep endoscopy represents the ‘gold standard’ in identifying the obstruction site, from the palatal level to laryngeal entry. Breathing impairment in sleep caused by the collapse of cervical trachea after previous tracheostomy has not yet been described in the literature.MethodsThis report presents two patients with severe obstructive sleep apnoea, in whom pre-operative drug-induced sleep endoscopy revealed upper airway and cervical trachea collapse at the level of previous tracheostomy.ResultsThe female patient was successfully treated with resection of hypertrophic tissue of the tongue base via lateral pharyngectomy, and resection of the collapsed segment of the trachea with primary reconstruction of the trachea by end-to-end anastomosis. The male patient was recommended continuous positive airway pressure therapy because of serious co-morbidities and high operative risk.ConclusionDrug-induced sleep endoscopy should always be used for visualisation of anatomical structures below the vocal folds in patients with a history of cervical trachea surgery. These two cases demonstrate the importance of drug-induced sleep endoscopy in planning conservative and surgical treatments, contributing significantly to operative success.

Abstract:

Obstructive sleep apnoea (OSA) is a sleep associated breathing disorder and it affects the health and quality of life of individuals suffering from it. Orthodontists should be well aware of the symptoms of this disorder and competent enough to recognize its signs and symptoms. Orthodontics is well suited for the treatment of OSA patients due to their expertise and knowledge regarding growth and development of orofacial and dentofacial structures as well as orthopaedic, orthodontic, and surgical correction of the jaws and other supporting tissues. There are basically two types of sleep apnoea- Central sleep apnoea and obstructive sleep apnoea where obstructive sleep apnoea is the more common one. This disorder can be life threatening as the oxygen supply to various parts of the body is substantially reduced. Obstructive sleep apnoea is caused by an interplay between a variety of factors, including sleep related loss of muscle tone in the tissues supplied by the glossopharyngeal nerve, anatomical obstruction of the nasal passages, large tonsils, large tongue, a retrognathic mandible, obesity, alcohol, sedative medication, and allergies. Sleep apnoea can be caused due to many factors and many treatment modalities have been employed to correct this disorder including mandibular advancement appliances, polysomnographs, and surgical intervention. It can be treated using surgery, continuous positive airway pressure and oral appliances therapy. This article highlights the role the orthodontist plays in the diagnosis and treatment planning of OSA patients. KEY WORDS Orthodontics, Obstructive Sleep Apnoea, Sleep, Snoring

Abstract:

Background: Sleep concerns are common in children with autism spectrum disorders (ASD). The impact of poor sleep on cognitive performance in ASD children is not well-established. We investigated the possible correlation between sleep quality in ASD children and cognitive performance. The Cambridge Neuropsychological Test Automated Battery (CANTAB) was administered to examine specific components of non-verbal cognition. Methods: The Children’s Sleep Habits Questionnaire (CSHQ) and actigraphy-measured data from 18 children with diagnosis of ASD were evaluated. Motor planning task (MOT), simple reaction time task (SRT) and the intradimensional/extradimensional shift (IED) of CANTAB were administered. Results: ASD good sleeper (ASD-GS) showed significant better response time for SRT task as compared to ASD poor sleeper (ASD-PS) based on CSHQ score. Parameters of bedtime resistance (r = 0.531, p = 0.023), sleep anxiety (r = 0.474, p = 0.047) from CSHQ and actigrapgy dependent (wake after sleep onset (WASO) (r = 0.430, p = 0.024) were significantly correlate with response time of SRT task. Conclusion: We conclude that some signs reflecting the presence of poor sleep in ASD correlate with various aspects of motor output on non-verbal performance tasks. The question is raised whether poor sleep in non-complaining persons with autism should be treated.

Abstract:

Background: Growing evidence highlights that elite rugby union players experience poor sleep quality and quantity which can be detrimental for performance. Objectives: This study aimed to i) compare objective sleep measures of rugby union players between age categories over a one week period, and ii) compare self-reported measures of sleep to wristwatch actigraphy as the criterion. Methods: Two hundred and fifty-three nights of sleep were recorded from 38 players representing four different age groups (i.e. under 16, under 18, senior academy, elite senior) in a professional rugby union club in the United Kingdom (UK). Linear mixed models and magnitude-based decisions were used for analysis. Results: The analysis of sleep schedules showed that U16 players went to bed and woke up later than their older counterparts (small differences). In general, players obtained seven hours of sleep per night, with trivial or unclear differences between age groups. The validity analysis highlighted a large relationship between objective and subjective sleep measures for bedtime (r = 0.56 [0.48 to 0.63]), and get up time (r = 0.70 [0.63 to 0.75]). A large standardised typical error (1.50 [1.23 to 1.88]) was observed for total sleep time. Conclusion: This study highlights that differences exist in sleep schedules between rugby union players in different age categories that should be considered when planning training. Additionally, self-reported measures overestimated sleep parameters. Coaches should consider these results to optimise sleep habits of their players and should be careful with self-reported sleep measures.

Abstract:

Aims: The aim was to investigate changes in child and adolescent sleep habits in Sweden over time. This had not been done previously. Methods: Cross-sectional questionnaire data over three decades of investigations of the Health Behaviours of School Children study (1985/1986, 2005/2006 and 2013/2014) were used. The sample included 18,682 children and adolescents, aged 11, 13 and 15. Empirically based age-specific sleep duration recommendations were used to operationalise sleep duration. Results: The results showed that, over time, fewer go to bed early and more go to bed late. Regarding sleep duration, there have been decreases in the proportion of children and adolescents that sleep as much as is recommended for their age. Sleep onset difficulties have increased for all ages and increase the odds of sleeping less than recommended as well as having late bedtimes. Boys were more likely than girls to have later bedtimes and to sleep less than recommended. A vocational educational track, not planning to study further or being unsure of which track to choose increased the odds for 15 year olds to have late bedtimes and to sleep less than recommended compared with a college preparatory track. Conclusions: The results indicate that over time, fewer children and adolescents attain sufficient sleep duration. This may have implications for study results, mental health and cognitive abilities.

Abstract:

OBJECTIVE To investigate the occurrence of daytime sleepiness and associated sleep factors in a sample of elementary school students who attended school in the afternoon schedule. METHODS Sleep data from 363 Brazilian public school students (12.78 ± 1.36 years, 206 girls) were obtained by applying questionnaires in classrooms. All subjects attended school in the afternoon schedule, with classes starting between 1:00 and 1:20 p.m. Daytime sleepiness was assessed by the pediatric daytime sleepiness scale; sleep quality, by the mini-sleep questionnaire; and sleep patterns and chronotypes, by the Munich chronotype questionnaire. Scores equal to or greater than 15 pediatric daytime sleepiness scale points were considered as excessive daytime sleepiness. The predictive power of sleep variables on daytime sleepiness was evaluated by a multiple linear regression. RESULTS The subjects in the sample had an average time in bed greater than nine hours both on school days and on weekends. Nevertheless, 52.1% had an average pediatric daytime sleepiness scale score equal to or greater than 15 points, indicative of excessive daytime sleepiness. As for their quality of sleep, 41.1% had a very altered sleep. We observed, by a multiple linear regression, that quality of sleep (β = 0.417), chronotype (β = 0.174), mid-sleep on school days (β = 0.138), and time in bed (β = - 0.091) were all significant in predicting daytime sleepiness. CONCLUSION This study showed the occurrence of excessive daytime sleepiness in non-sleep deprived students who attended school in the afternoon. The worst quality of sleep and eveningness had a greater predictive power on daytime sleepiness than time in bed. Therefore, we must consider other factors in addition to sleep duration when planning interventions for daytime sleepiness.

Abstract:

Abstract Introduction Literature suggests that stress may play an important role in sleep disturbance. Individuals with higher stress levels often showed hyperarousal to stressful events, possibly leading to sleep disturbance. Hyperarousal is also one of features of stress-related sleep disturbance. Here, we examined the extent to which stress levels interact with neural activity in response to sleep-related information to predict sleep disturbance. Methods Forty eight healthy adults (26 females, age = 35.7 ± 10.5) without sleep disorders based on nocturnal polysomnography participated in this study. They were viewing sleep-related pictures (e.g., bedroom and sunset) and non-sleep related, neutral pictures (e.g., kitchen and landscape) during fMRI scanning. They also completed questionnaires assessing stress levels and sleep disturbance using Life Experience Survey (LES) and Pittsburgh Sleep Quality Index (PSQI), respectively. Activity in response to sleep-related pictures compared to neutral pictures was extracted from our region-of-interest (ROI), the anterior insula, and entered into our moderation models. The SPSS macro PROCESS (Hayes, 2013) was used to conduct moderation analyses. Given a significant correlation between age and PSQI scores, age was included as a covariate. Results Our moderation analyses showed that interactions between stress levels and anterior insula response to sleep-related pictures significantly predicted sleep disturbance. Simple slope analyses showed that at higher anterior insula response, higher stress levels were associated with greater sleep disturbance, but at lower anterior insula response, stress was not significantly associated with sleep disturbance. These results indicate that individuals with high levels of stress were more likely to experience sleep disturbance if they showed greater anterior insula response to sleep-related pictures (i.e., hyperarousal in response to sleep-related information). Conclusion The current findings suggest that interactions between stress levels and neural substrates of hyperarousal, particularly the anterior insula, may play a critical role in sleep disturbance.

Abstract:

BACKGROUND: Fatigue is an insidious and costly occurrence in the aviation community, commonly a consequence of insufficient sleep. Some organizations use scheduling tools to generate prescriptive sleep schedules to help aircrew manage their fatigue. It is important to examine whether aircrew follow these prescriptive schedules, especially in very dynamic environments. The current study compares aircrew sleep during missions to prescriptive sleep schedules generated by a mission scheduling tool. METHODS: Participating in the study were 44 volunteers (Mage= 28.23, SDage= 4.23; Proportionmale= 77.27%) from a C-17 mobility squadron providing 25 instances of sleep and mission data (80 flights total). Aircrew wore actigraph watches to measure sleep during missions and prescriptive sleep schedules were collected. Actual and prescriptive sleep was compared with calculated performance effectiveness values per minute across mission flights. RESULTS: Prescriptive schedules generally overestimated effectiveness during missions relative to estimated actual sleep, potentially causing shifts in effectiveness to ranges of increased risk requiring elevated fatigue mitigation efforts. Actual and prescriptive effectiveness estimates tended to increasingly diverge over the course of missions, which magnifies differences on longer missions. DISCUSSION: The current study suggests that aircrew sleep during missions often does not align with prescriptive sleep schedules generated by mission planning software, resulting in effectiveness estimates that are generally lower than predicted. This might discourage aircrew from using mission effectiveness graphs as a fatigue mitigation tool. Additionally, because fatigue estimates factor into overall operational risk management processes, these schedules might underestimate risks to safety, performance, and health.

Abstract:

The aim of this article is to outline and discuss theoretical approaches to the study of family life and to make suggestions about how these approaches might apply in planning and carrying out empirical research on sleep. It argues that, while theories about power and gender can inform research on sleep, the findings from research on sleep will help to extend and enrich theoretical approaches to family life and the social order. The article is concerned especially with gendered power relations and with ‘sharing sleep’. It draws on Morgan's sociological analysis of family life, and on the distinction he makes between the political economy, the moral economy and the emotional economy. It uses research findings on the allocation of money and on domestic violence to examine different theoretical approaches and to consider how these theories might be used in research on sleep. In the past many of the battles which rage within bedrooms were individualised as ‘her’ or ‘his’ fault. Applying sociological understanding and theoretical approaches may enable some of these individual and very private troubles to be seen as more general issues, while making a contribution to the new sociology of sleep.

Abstract:

ABSTRACT For patients with severe obstructive sleep apnea syndrome (OSAS), maxillomandibular advancement (MMA) offers a good treatment option by physically expanding the skeletal framework. However, facial esthetics can be aggravated by MMA in patients with OSAS who have a normally positioned maxilla, a protrusive upper lip, and an acute nasolabial angle. Therefore, surgical treatment planning should be customized according to diverse skeletodental and soft-tissue patterns to produce a favorable change in facial esthetics and sleep function in patients with OSAS. In this case report, good treatment results were achieved in a young female patient with OSAS and skeletal Class II, a normally positioned maxilla, a protrusive upper lip, and acute nasolabial angle by impaction of the maxilla, autorotation/advancement of the mandible, and advancement of the chin. A customized flowchart for surgical treatment planning in OSAS that considers facial esthetics was suggested.

Esophageal and epiglottic pressure deflection measurements are widely used as gold-standard measures of ventilatory effort during sleep without consideration of differential obstruction effects between measurement sites. This study is the first to quantify the effect of airway occlusion on esophageal versus epiglottic pressure recordings during sleep. The findings of substantial acute effects of occlusion itself on esophageal and particularly epiglottic pressure deflections are important to consider in the planning, analysis, and interpretation of studies that rely on pressure deflections for inferences regarding inspiratory effort.

Objective: to identify care interventions, performed by the health team, and their influence on the continuity of sleep of patients hospitalized in the Intensive Care Unit.Method: descriptive study with a sample of 12 patients. A filming technique was used for the data collection. The awakenings from sleep were measured using the actigraphy method. The analysis of the data was descriptive, processed using the Statistical Package for the Social Sciences software.Results: 529 care interventions were identified, grouped into 28 different types, of which 12 (42.8%) caused awakening from sleep for the patients. A mean of 44.1 interventions/patient/day was observed, with 1.8 interventions/patient/hour. The administration of oral medicine and food were the interventions that caused higher frequencies of awakenings in the patients.Conclusion: it was identified that the health care interventions can harm the sleep of ICU patients. It is recommended that health professionals rethink the planning of interventions according to the individual demand of the patients, with the diversification of schedules and introduction of new practices to improve the quality of sleep of Intensive Care Unit patients.

Abstract:

Sleep stage scoring is necessary for diagnosing several sleep disorders. However, it is an intensive and repetitive task and a vital automation candidate. This work seeks to evaluate different kinds of Machine Learning based classification algorithms available in the scientific literature to determine which one fits better the clinical practice requirements. The comparison is made with a predefined experimental design, using electroencephalography, electrooculography, and electromyography signals from the polysomnographic records of the Sleep-EDFx dataset. The comparison considers the accuracy and speed of algorithms based on Linear Discriminate Analysis, Support Vector Machines, Random Forests, and Artificial Neural Networks. The latter group includes the Deep Neural Networks DeapFeatureNet, based on Convolutional Neural Networks, and DeepSleepNet, additionally based on Recurrent Neural Networks. It is determined that several of the tested algorithms boast high accuracy levels (85%). From them, DeepSleepNet is chosen as the fittest due to its considerable advantage in execution time. Nevertheless, the final result should always be reviewed by the experts.

Abstract. The aim of this article was to review research studies related to the issues of sleep in older adults, examining the relationship between sleep quality and a set of psychological variables of daytime functioning in healthy older adults: quality of life, subjective health, functional ability, cognitive function, and emotional state, in Europe. Combined scoping review search strategies resulted in a total of 84 articles selected for review. We conclude there is a considerable amount of European research on sleep quality and its correlates in older adults’ population. Studying these relationships may be the basis for the targeted planning of psychological interventions aiming at raising the quality of life in older adults. The selected domains of older adults’ everyday functioning were all well represented in the retrieved research studies.

Abstract:

The main purpose of the present study was to explore the associations of sleep duration and sleep quality with self-rated health. In this cross-sectional study, participants were 894 elderly individuals. Self-rated health, sleep duration, and sleep quality were self-reported. The associations were examined using multiple logistic regression analyses.After adjusting for sex, physical activity, smoking consumption, alcohol consumption, psychological distress, socioeconomic status, and chronic disease/s, sleeping <6 h (OR (Odds ratio) = 3.21; 95% CI (95 percent confident interval) 1.61 to 6.39), 6–7 h (OR = 2.47; 95% CI 1.40 to 4.36), 8–9 h (OR = 3.26; 95% CI 1.82 to 5.83), and >9 h (OR = 3.62; 95% CI 1.57 to 8.34) and having ‘poor’ sleep quality (≥5 points; OR = 2.33; 95% CI 1.46 to 3.73) were associated with ‘poor’ self-rated health. When sleep duration and sleep quality were entered simultaneously into the model, the same associations remained. Our findings provide evidence that both ‘short’ and ‘long’ sleep and ‘poor’ sleep quality are associated with ‘poor’ self-rated health. Thus, interventions that promote healthy sleep hygiene in the elderly are warranted.
