Abstract
Sleep is vital in preserving mental and physical well-being by aiding bodily recovery, strengthening the immune system, and regulating hormones. It enhances memory, concentration, and mood regulation, reducing stress and anxiety. Sleep deprivation, a common phenomenon affecting approximately 20% of adults, decreases performance, alertness, and health integrity. Furthermore, it triggers physiological changes, including increased stress hormone levels, leading to various disorders such as hyperglycemia and hypertension. Recent research explores the role of extracellular vesicles (EVs) in sleep-related conditions. EVs, released by cells, play vital roles in intercellular communication and biomarker potential. Studies indicate that sleep deprivation influences EV release, impacting cancer progression, endothelial inflammation, and thrombosis risk. Understanding these mechanisms offers insights into therapeutic interventions. Thus, multidisciplinary approaches are crucial to unraveling the complex interactions between sleep, EVs, and health, providing direction for effective prevention and treatment approaches for sleep disorders and related conditions.

Abstract
Objective: This pilot study assessed the effects of electronic noise-masking earbuds on subjective sleep perception and objective sleep parameters among healthcare workers (HCWs) reporting sleep difficulties during the COVID-19 pandemic. Methods: Using a pre-post design, 77 HCWs underwent 3 nights of baseline assessment followed by a 7-night intervention period. Participants wore an at-home sleep monitoring headband to assess objective sleep measures and completed subjective self-report assessments. The difference in mean sleep measures from baseline to intervention was estimated in linear mixed models. Results: Compared to baseline assessments, HCWs reported significant improvements in sleep quality as measured by the Insomnia Severity Index (ISI) (Cohen's d = 1.74, p < 0.001) and a significant reduction in perceived sleep onset latency (SOL) during the intervention (M = 17.2 minutes, SD = 7.7) compared to baseline (M = 24.7 minutes, SD = 16.1), (Cohen's d = -0.42, p = 0.001). There were no significant changes in objective SOL (p = 0.703). However, there was a significant interaction between baseline objective SOL (<20 minutes vs >20 minutes) and condition (baseline vs intervention) (p = 0.002), such that individuals with objective SOL >20 minutes experienced a significant decrease in objective SOL during the intervention period compared to baseline (p = 0.015). Conclusions: HCWs experienced a significant improvement in perceived SOL and ISI scores after using the electronic noise-masking earbuds. Our data provide preliminary evidence for a nonpharmacological intervention to improve the sleep quality of HCWs which should be confirmed by future controlled studies.

Abstract
Although the impact of sleep loss on social behaviors has been widely observed in recent years, the mechanisms underpinning these impacts remain unclear. In this study, we explored the detrimental effects of sleep deprivation on reciprocity behavior as well as its underlying psychological and neuroimaging mechanisms by combining sleep manipulation, an interpersonal interactive game, computational modeling and neuroimaging. Our results suggested that after sleep deprivation, individuals showed reduced reciprocity behavior, mainly due to their reduced weights on communal concern when making social decisions. At neural level, we demonstrated that sleep deprivation's effects were observed in the precuneus (hyperactivity) and temporoparietal junction, dorsal lateral prefrontal cortex (DLPFC) (both hypoactivity), and reduced reciprocity was also accounted for by increased precuneus-thalamus connectivity and DLPFC-thalamus connectivity. Our findings contributed to the understanding of the psychological and neuroimaging bases underlying the deleterious impact of sleep deprivation on social behaviors.

Abstract
Sleep deprivation, which is a decrease in duration and quality of sleep, is a common problem in today's life. Epidemiological and interventional investigations have suggested a link between sleep deprivation and overweight/obesity. Sleep deprivation affects homeostatic and non-homoeostatic regulation of appetite, with the food reward system playing a dominant role. Factors such as sex and weight status affect this regulation; men and individuals with excess weight seem to be more sensitive to reward-driven and hedonistic regulation of food intake. Sleep deprivation may also affect weight through affecting physical activity and energy expenditure. In addition, sleep deprivation influences food selection and eating behaviours, which are mainly managed by the food reward system. Sleep-deprived individuals mostly crave for palatable energy-dense foods and have low desire for fruit and vegetables. Consumption of meals may not change but energy intake from snacks increases. The individuals have more desire for snacks with high sugar and saturated fat content. The relationship between sleep and the diet is mutual, implying that diet and eating behaviours also affect sleep duration and quality. Consuming healthy diets containing fruit and vegetables and food sources of protein and unsaturated fats and low quantities of saturated fat and sugar may be used as a diet strategy to improve sleep. Since the effects of sleep deficiency differ between animals and humans, only evidence from human subject studies has been included, controversies are discussed and the need for future investigations is highlighted.

Abstract
OBJECTIVES To evaluate patients' sleep quality in a former hospital with two-and four-bedded rooms compared to a new hospital that incorporated evidence-based design features, including exclusively single-patient rooms (SPRs). BACKGROUND Hospitalized patients often report poor sleep quality due to both patient-related factors and hospital environmental factors. It is unclear if staying in an SPR in a hospital designed as a healing environment is associated with better sleep quality. METHODS In a before-after study, sleep quality, duration, and efficiency over 72 hr were measured with a sleep diary, GENEActiv accelerometer, and the Richards-Campbell Sleep Questionnaire (RCSQ) with scores ranging from 0 to 100, with higher scores reflecting better sleep. Participants were either staying alone in the former hospital with two-and four-bedded rooms (Group 1), sharing a room with one to three fellow patients (Group 2), or staying alone in a newly designed hospital with 100% SPRs (Group 3). RESULTS We included 17 patients in Group 1, 32 patients in Group 2, and 56 patients in Group 3. Univariable linear mixed model analysis, controlling for night number, revealed that the RCSQ total score was lowest in Group 2 compared to the other two groups. In the multivariable analysis, the RCSQ score was also the lowest in Group 2, with a significant effect from covariate "use of night medication." CONCLUSION Self-reported sleep quality of hospitalized patients in a hospital with 100% SPRs designed as a healing environment was slightly better than that of patients staying in multioccupancy rooms with fellow patients.

Abstract
BACKGROUND As a common postsurgery complication, sleep deprivation (SD) can severely deteriorate the cognitive function of patients. Enriched environment (EE) exposure can increase children's cognitive ability, and whether EE exposure could be utilized to alleviate postsurgery SD-induced cognitive impairments is investigated in this study. METHODS Open inguinal hernia repair surgery without skin/muscle retraction was performed on Sprague-Dawley male rats (9-week-old), which were further exposed to EE or standard environment (SE). Elevated plus maze (EPM), novel object recognition (NOR), object location memory (OLM), and Morris Water Maze assays were utilized to monitor cognitive functions. Cresyl violet acetate staining in the Cornusammonis 3 (CA3) region of rat hippocampus was used to detect neuron loss. The relative expression of brain-derived neurotrophic factor (BDNF) and synaptic glutamate receptor 1 (GluA1) subunits in the hippocampus were detected with quantitative reverse transcription polymerase chain reaction (RT-qPCR), Western blots, enzyme-linked immunosorbent assay (ELISA), and immunofluorescence. RESULTS EE restored normal levels of time spent in the center, time in distal open arms, open/total arms ratio, and total distance traveled in the EPM test; EE restored normal levels of recognition index in the NOR and OLM test; EE restored normal levels of time in the target quadrant, escape latencies, and platform site crossings in the Morris Water Maze test. EE exposure decreased neuron loss in the CA3 region of the hippocampus with increased BDNF and phosphorylated (p)-GluA1 (ser845) expression. CONCLUSION EE ameliorates postsurgery SD-induced cognitive impairments, which may be mediated by the axis of BDNF/GluA1. EE exposure could be considered as an aid in promoting cognitive function in postsurgery SD.

Abstract
Gut microbiota comprises the microbial communities inhabiting our gastrointestinal (GI) tracts. Accordingly, these complex communities play a fundamental role in many host processes and are closely implicated in human health and diseases. Sleep deprivation (SD) has become increasingly common in modern society, partly owing to the rising pressure of work and the diversification of entertainment. It is well documented that sleep loss is a significant cause of various adverse outcomes on human health including immune-related and metabolic diseases. Furthermore, accumulating evidence suggests that gut microbiota dysbiosis is associated with these SD-induced human diseases. In this review, we summarize the gut microbiota dysbiosis caused by SD and the succedent diseases ranging from the immune system and metabolic system to various organs and highlight the critical roles of gut microbiota in these diseases. The implications and possible strategies to alleviate SD-related human diseases are also provided.

Abstract
The relationship between sleep dynamics and blood pressure (BP) changes is well established. Moreover, sleep efficiency and wakefulness during sleep (WASO) events have a significant impact on BP dipping. Despite this knowledge, there is limited research on the measurement of sleep dynamics and continuous blood pressure (CBP). This study aims to explore the relationship between sleep efficiency and cardiovascular function indicators such as pulse transit time (PTT), as a biomarker of CBP, and heart rate variability (HRV), measured using wearable sensors. The results of the study conducted on 20 participants at the UConn Health Sleep Disorders Center suggest a strong linear relationship between sleep efficiency and changes in PTT (r2 = 0.8515) and HRV during sleep (r2 = 5886). The findings of this study contribute to our understanding of the relationship between sleep dynamics, CBP, and cardiovascular health.

Abstract
OBJECTIVE Obstetrics is a constraining specialty due to heavy workloads and repeated stressful situations. French maternity wards are facing many difficulties to recruit, as a consequence of the conversion of a significant number of Obstetrician-Gynecologists (OB-GYNs) to exclusive daily private practice. The aim of this study was to evaluate the quality of life (QOL) of OB-GYNs in order to identify burnout risk factors, develop prevention strategies and therefore ensure patient safety. STUDY DESIGN A Google forms questionnaire assessing QOL and life/work balance was distributed by e-mail to 1397 members of the National College of French OB-GYNs (CNGOF). This was a declarative multicenter cross-sectional survey. RESULTS Four hundred sixty-one responses were collected (response rate 30%). A burnout episode was reported by 31.3% of respondents. Main burnout risk factors were limited staff on the on-call schedule (p = 0.008) and low salary (p < 0.001). On-call work was considered to have a negative personal life impact by 57.8% of the sample; 34.1% wanted to stop this practice and 81.3% believed that financial compensation would help reinforce its attractiveness. Medico-legal risks influenced the daily practices of 70% of respondents and 86.8% had been personally affected by media coverage of obstetrical violence. CONCLUSIONS This report confirms a high burnout rate within a stressful profession, with major impacts from on-call activity, insufficient salary relative to the arduousness of this practice, high exposure to medico-legal actions and media attention. Revising shift duration to a maximum 12 h, better control over global workload, higher salary and renewed social recognition are urgent priorities.

Abstract
PURPOSE Sleep problems are common and affect approximately 36-70% of older adults worldwide and can be associated with negative outcomes such as pain. There is believed to be a bidirectional relationship between sleep problems and pain, modulated by inflammation and stress. The objective was to investigate the association between self-reported sleep problems and pain manifestations. METHODS A cross-sectional study using data from the second wave of the Brazilian Longitudinal Study of Aging (2019-2021) was conducted. The exposure variables were self-reported sleep problems: poor sleep quality, insomnia (initial, intermediate, and final), and daytime sleepiness. The outcomes were self-reported pain manifestations: frequent pain, moderate/intense/strong pain, and pain-related disability. Logistic regressions were performed to verify the association between exposures and outcomes. RESULTS A total of 6875 community-dwelling older adults participated in this study (71.1 ± 8.3 years; 54.4% female). Older adults with self-reported poor sleep quality, initial, intermediate and final insomnia, and daytime sleepiness had, respectively, 1.99 (95% CI 1.57-2.53), 1.47 (95% CI 1.11-1.97), 1.65 (95% CI 1.27-2.14), 1.69 (95% CI 1.29-2.22), and 1.76 (95% CI 1.35-2.29) greater odds of reporting frequent pain. The odds of moderate/intense/strong pain were higher in older adults that reported poor sleep quality (OR: 2.21; 95% CI 1.08-4.51). Older adults with self-reported poor sleep quality, initial, intermediate and final insomnia, and daytime sleepiness had, respectively, 1.84 (95% CI 1.11-3.02), 1.73 (95% CI 1.14-2.62), 1.80 (95% CI 1.19-2.73), 1.58 (95% CI 1.07-2.34), and 1.63 (95% CI 1.11-2.39) greater odds of reporting pain-related disability. CONCLUSION Self-reported sleep problems are associated with pain manifestations in older adults. The results may help in the proposition of programs and public health policies.

Abstract
The overarching importance of sleep was further emphasized during the pandemic of COVID-19. The subjects infected by COVID-19 frequently experience sleep disturbances; some are long-lasting problems and decrease the quality of life. Insomnia is the most studied sleep disorder associated with COVID-19. Insomnia affects patients who have experienced an infection and the general population. Good sleep is important in maintaining mental and physical health, including immune system functions. The interconnections between insomnia, the immune system, and COVID-19 are complex. Insomnia triggers numerous immune system dysregulations and makes individuals more vulnerable to respiratory infections. This narrative review overviews the influence of the COVID-19 pandemic on the immune system through sleep disorders.

Abstract
The incidence of diabetes mellitus (DM) is increasing exponentially globally, with 90% of the confirmed cases being type 2 DM. The global incidence of DM is expected to increase by 48% during 2017-2045. The coronavirus disease 2019 (COVID-19) pandemic continues to have a massive impact on human health, causing sudden lifestyle changes through quarantine measures, such as lockdown, social distancing, various curfews, and isolation at home. This in turn might increase the risk of developing numerous chronic diseases, such as DM, obesity, and cardiovascular diseases, which increase the severity of COVID-19. To this end, we performed a comprehensive review to determine viable measures for the prevention of DM and its subsequent upsurge globally. Additionally, we have determined strategies that should be adopted globally to ensure a healthy lifestyle during the COVID-19 pandemic and later.

Abstract
The review article enlightens contemporary concept about a role of sleep in cellular energy metabolism, neuroplasticity and glymphatic clearance of waste products. Many researches have demonstrated that prolonged wakefulness is an energetic and a neurophysiologic issue for the brain. The article provides description of biochemical processes that are responsive for energy restoration in sleep, particularly the role of ATP, adenosine and glycogen. Energy metabolism substrates depletion leads to endoplasmic reticulum stress and unfolded protein response. At the same time the conductance of synapses increases that worsens energetic problems. Level of the glymphatic clearance during wakefulness is substantially lower in comparison with sleep, and waste products are not removed fast enough.

Abstract
PURPOSE OF REVIEW We reviewed current evidence on the impact of coronavirus disease 2019 (COVID-19) pandemic on sleep of different populations. RECENT FINDINGS Several studies demonstrated that sleep deprivation may cause immune system dysregulation, which deteriorates the course of COVID-19. The increased prevalence of sleep disorders among COVID-19 patients has been associated with more severe disease and worse clinical outcomes. Healthcare workers who were subjected to atypical workload and more nightshifts developed sleep disorders which associated with work-related errors and COVID-19 infection susceptibility. In general population, circadian misalignment and excessive stressors impaired sleep quality. Sleep dysfunction has been recorded due to the pandemic. It is essential to implement interventions in order to alleviate pandemic-related sleep disorders. Telemedicine, cognitive behavioral therapy, and sleep hygiene practices appear to be helpful. Psychotropic medication should be cautiously administered, while other pharmacological agents, such as melatonin, have shown promising results.

Abstract
Objective Okra, possessing various bioactive components, is used to treat different diseases. This study sought to estimate the intervention effects of okra extract (OE) on brain-gut peptides (BGPs) and intestinal microorganisms in sleep deprivation (SD) rats. Methods SD rat models were established using the modified multiple platform method and then treated with normal saline, diazepam tablets, or different doses of OE. Body weight and average daily water consumption of rats were recorded. Depressive behaviors of rats were assessed by the open field test and sucrose preference test. Serum levels of noradrenaline, melatonin, inflammatory factors (IL-1β/IL-6/TNF-α/IL-4/IL-10), and BGP indexes, including gastrin (GAS), motilin (MTL), 5-hydroxytryptamine (5-HT), cholecystokinin (CCK), and vasoactive intestinal peptide (VIP) were measured by ELISA. Additionally, the DNA relative contents of representative intestinal microorganisms in the collected rat feces were determined using RT-qPCR. Results SD decreased body weight and average daily water consumption and induced depressive behaviors as well as stress and inflammatory responses in rats. SD rats exhibited lowered GAS, MTL, 5-HT, and VIP but elevated CCK and showed diminished DNA relative contents of Bacteroidetes and probiotics (Bifidobacteria and Lactobacilli) but increased Clostridium perfringens. OE at different doses ameliorated the depressive behaviors and mitigated the stress and inflammatory responses in SD rats, raised the serum contents of GAS, MTL, 5-HT, and VIP, reduced CCK level, elevated the DNA relative contents of Bacteroidetes and probiotics, but diminished Clostridium perfringens. OE exhibited similar intervention effects to diazepam tablets (positive control). Conclusion OE exerts intervention effects on BGPs and intestinal microorganisms in SD rats.

Abstract
Healthy sleep is required to ensure the body’s homeostatic stability, the consistency of immunological reactions, and optimum functioning of the internal organs, the nervous system, and cognitive functions. Patterns of changes to the circadian rhythms have been studied in many diseases, though infection with SARS-CoV-2 is a new reality and the basic mechanisms of functioning of the body in this pathology require deeper investigation. Despite the difficulty of analytical investigations in pandemic conditions, experience of the diagnosis of COVID-19 has now been acquired and treatment algorithms have been developed for different clinical situations; vaccines have been developed. Least studied are questions of the long-term sequelae of COVID-19. At the same time, there are good grounds for suggesting that patients need long-term rehabilitation in the post-covid period of SARS-CoV-2, for reasons including damage to the nervous system. Analysis of publications – from descriptions of clinical cases to literature reviews – allows empirical experience to be accumulated, providing the opportunity for future identification of prognostic markers for the disease for effective prevention of long-term sequelae. The results of current prospective studies draw attention to the occurrence of dyssomnia and obstructive sleep apnea not only as a common consequence of coronavirus infection, but also as a factor significantly worsening the prognosis in the acute period of illness. It has repeatedly been shown that sleep deprivation has adverse influences on the body’s resistance, including to SARS-CoV-2, and requires correction to improve prognoses in the acute and long-term periods of illness in COVID-19 patients.

Abstract
Chronic sleep deprivation (SD) is a common problem for humans and can lead to many deleterious effects, including depression, anxiety, stroke, permanent cognitive deficits, stress, and other physiological diseases. It is vital to acquire information about the relevant neural activities at the whole-brain level to systematically explore the mechanisms of brain dysfunction related to SD. Expression of the immediate-early gene (IEG) Fos in the mouse brain has been widely used as a functional marker of brain activity in the field of neuroscience. However, most previous studies only analyzed the change of c-Fos in several specific brain regions using traditional research methods or in short-term SD model. Here, we applied c-Fos mapping through the fluorescence micro-optical sectioning tomography (fMOST) technique and AAV-PHP.eB to comprehensive analysis the state of cumulative activation across the whole brain in a mouse model of chronic SD. The chronic rapid eyes movement (REM) SD model was induced by moving mice to a separate holding area filled with water. The experimental period lasted for 6 h per day. The results showed that after 14 days of SD, the mice displayed anxiety-like behaviors in open field test and elevated plus maze test, and displayed depression-like behaviors in tail suspension test and the sucrose preference test. The c-Fos + cells were detected in a maximum of 230 brain regions. SD-induced stress model evoked c-Fos expression in several brain regions compared to the control group. In particular, the isocortex-cerebral cortex plate area, including the retrosplenial, anterior cingulate, agranular insular, gustatory, and parasubiculum, appear to be the most sensitive regions after chronic REM SD.

Abstract
Recognition of how physicians contemplate and approach their activities, positive or negative, may shed light into a more holistic depiction of physician well-being. The purpose of this work was to develop items to measure wise cognitive exertion, constructed with Stoic thought, and determine its association with physician stress, well-being, and life satisfaction. A survey was sent to physicians and university staff members. This pilot investigation found a relationship among focusing on a purposeful life, acknowledging locus of control, avoiding wasteful cognition, and taking (good or bad) life experiences for personal growth and superior life satisfaction, well-being and lower stress. A 13-Item Wise Exertion Scale was developed and had significant associations with stress, well-being, and life satisfaction. Each of the four factors from the 13-Item Wise Exertion Scale were significantly associated with each measure with the exception of Control Consciousness and life satisfaction. Within physicians (N = 59), the 13-Item Wise Exertion Scale was a significant predictor, after adjusting for demographics with stress, well-being, and life satisfaction. Physicians had significantly lower 13-Item Wise Exertion Scale scores compared to non-physicians (N = 126). Future inquiries are required to determine if physicians with a mindset assembled with these beliefs have superior well-being.

Abstract
Sleep deprivation (SD) leads to memory and cognitive impairment due to damage to the hippocampus. Isoquercetin possesses neuron-protective properties. Our study aimed to investigate the effects of isoquercetin on SD-induced hippocampal neurons damage and the underlying mechanism. Herein, the cognitive competence was evaluated by Morris water maze (MWM) test after SD. The morphology of the hippocampus was observed after Nissl staining. Moreover, the level of NLRP3 was detected by Immunofluorescent staining and western blot. In vitro study, pyroptosis was tested by TUNEL assay and flow cytometry. The levels of pyroptosis-related factors were measured by western blot. The results indicated that isoquercetin improved spatial memory and prevented change of hippocampal neurons of SD mice. Moreover, SD upregulated NLRP3 level, which was downregulated by isoquercetin. Additionally, isoquercetin rescued the increase of pyroptosis and the upregulation of NLRP3, caspase-1, ASC, IL-1β, IL-18, and GSDMD levels induced by LPS. In conclusion, isoquercetin improved learning and cognitive capability of SD mice via suppressing NLRP3-induced pyroptosis of hippocampal neurons cells, suggesting that isoquercetin might be an efficacious drug for memory disorders caused by SD.

Abstract
Sleep characteristics vary between populations. Detrimental sleep habits have cognitive consequences leading to daytime functioning debilitation. Until now no study has been done to investigate sleep characteristics in Iran thoroughly. In this study, we aimed to evaluate Iranians’ sleep characteristics and their association with daytime functioning. We conducted a population-based study from January 2017 to May 2019 on people more than 18 years old who lived in 11 urban destricts and 3 rural areas of Tehran, Iran. We randomly selected the participants using a multistage random stratified clustered sampling method. We obtained the participants’ demographic and anthropometric characteristics and details of bedtime, sleep duration, sleep onset latency, wake-up time and sleep impact on daytime functioning. Logistic regression model was used to assess the relationship between sleep characteristics) and daytime functioning. In total, 1830 people with a mean age of 40.83 years participated in the study. The gender distribution of the participants was even, and 70.98% of them were married. After adjusting for age and sex, the following three factors had a significant impact on daytime functioning: bedtime, sleep onset latency, and sleep duration. (OR = 1.12, P < 0.038, OR = 1.01, P < 0.011, and OR = 0.99, P = 0.01, respectively). We also found that longer sleep onset latency (P = 0.004) and shorter sleep durations (P = 0.029) significantly interfere with daytime functioning. Iranians’ sleep characteristics, especially their sleep duration and sleep onset latency, are associated with their daytime function. Interventions on people’s sleep hygiene are warranted to promote healthier sleep behaviors among Iranians, considering the high impact of current sleep characteristics on their daily lives.

Abstract
STUDY OBJECTIVES Whether short or insufficient sleep were risk factors for new onset nocturnal gastroesophageal reflux (nGER). METHODS In this 10-year longitudinal study, adult general population women in Uppsala, Sweden, answered questionnaires on sleep, nGER and other conditions on two occasions. Participants at baseline totaled 6,790, while participants at follow-up totaled 4,925. "Short sleep" was defined as sleeping <6 hours/night and "insufficient sleep" was defined as reporting an average actual sleep duration below 80% of the self-estimated need for sleep duration but without "short sleep". nGER was defined as reporting heartburn or acid reflux after going to bed sometimes, often, or very often. The confounding factors age, body mass index, physical activity, caffeine intake, smoking habits, alcohol dependence, depression, anxiety, and snoring were defined from the questionnaire. RESULTS At baseline, 839 participants reported short sleep and 1,079 participants were defined as having insufficient sleep. Both participants with insufficient sleep and short sleep had nGER more often than those with sufficient sleep (26% vs 17% vs 10% respectively). At follow-up, a new onset of nGER was twice as common among those with insufficient or short sleep at baseline and follow-up, compared with those with sufficient sleep at baseline and follow-up, even after adjusting for confounding factors (OR 2.0 (1.5-2.8), p<0.001). CONCLUSIONS Insufficient sleep and short sleep were associated with nGER. Persistent insufficient and/or short sleep independently increased the risk of developing nGER over a 10-year follow-up. Women seeking for nGER should be questioned about their sleep habits to identify insufficient sleep as a possible causative factor.

Abstract
Background Sleep deprivation (SD) among young adults is a major public health concern. In humans, it has adverse effects on mood and results in serious health problems. Faced with SD, persons may take precautionary measures to try and reduce their risk. The aim of this study is to evaluate the efficacy and safety of electroacupuncture (EA) for the prevention of negative moods after SD. In addition, we will do a comparison of the effects of EA on mood after SD at different time points. Methods This randomized controlled trial (RCT) will be performed at the First Affiliated Hospital of Changchun University of Chinese Medicine in China. The Standards for Reporting Interventions in Clinical Trials of Acupuncture 2010 will be strictly adhered to. Forty-two healthy male volunteers will be distributed into acupoints electroacupuncture (AE) group, non-acupoints electroacupuncture (NAE) control group, or blank control group. This trial will comprise 1-week baseline (baseline sleep), 1-week preventative treatment, 30-h total sleep deprivation (TSD), and 24-h after waking follow-up period. Participants in the AE group and the NAE control group during the preventative treatment period will be administered with EA treatment once daily for 1 week. Participants in the blank control group will not be administered with any treatment. The primary outcome will be the Profile of Mood States (POMS) Scale. Secondary outcome measures will include changes in the Noldus FaceReader (a tool for automatic analysis of facial expressions) and Positive and Negative Affect Schedule (PANAS) Scale. Total sleep deprivation will be 30 h. During the 30-h TSD period, participants will be subjected to 11 sessions of assessment. Adverse events will be recorded. Discussion This study is designed to evaluate the efficacy and safety of EA for the prevention of negative moods after SD. The results of this trial will allow us to compare the effects of EA on mood after SD at different time points. Moreover, the findings from this trial will be published in peer-reviewed journals.

Abstract
Circadian rhythm disorder (CRD) in space flight can lead to memory impairment, performance decrements and adverse health outcomes, the main manifestations of which are circadian desynchronization, sleep loss and insomnia. Sleep deprivation (SD) provide the means to evaluate these effects and the risks associated with CRD on ground. Gastrodia elata Blume (GEB) has beneficial effects on the treatment of sleep disturbances and memory loss. Fresh GEB (FG), an unprocessed raw tuber of GEB, has been used as functional health food in Asian countries for a long time. However, the research report of FG to ameliorate memory impairment caused by insomnia or lack of sleep is meager. In this study, ICR male mice were sleep-deprived continuously and water extract of FG (WFG) was orally administrated (3 and 9 g/kg/d, i.g) during the SD process lasted for 25 days, except control and model groups gavage administration with water, positive control group with modafinil (MOD, 0.1 g/kg/d, i.g). We studied the effect of WFG on CRD-induced learning and memory impairment using a set of behavioral analyses including the object location recognition test (OLRT), novel object recognition test (NORT), and the passive avoidance test (PAT). In addition, oxidative stress parameters were assessed by measuring the malondialdehyde (MDA) and superoxide dismutase (SOD) reactivity in serum and hippocampus. Our results revealed that SD decreased discrimination index (DI) in OLRT and NORT, with shorter latency into the dark chamber in PAT. Both WFG and MOD treatment can reverse these changes (P < 0.05). We concluded that WFG treatment improve CRD-induced learning and memory impairment and oxidative stress damage which makes FG a promising candidate as herbal health product of memory decline in CRD.

Abstract
Sleep is an evolutionarily conserved phenomenon, being an essential biological necessity for the learning process and memory consolidation. The brain displays two types of electrical activity during sleep: slow-wave activity or non-rapid eye movement (NREM) sleep and desynchronized brain wave activity or rapid eye movement (REM) sleep. There are many theories about "Why we need to sleep?" among them the synaptic homeostasis. This theory proposes that the role of sleep is the restoration of synaptic homeostasis, which is destabilized by synaptic strengthening triggered by learning during waking and by synaptogenesis during development. Sleep diminishes the plasticity load on neurons and other cells to normalize synaptic strength. In contrast, it re-establishes neuronal selectivity and the ability to learn, leading to the consolidation and integration of memories. The use of zebrafish as a tool to assess sleep and its disorders is growing, although sleep in this animal is not yet divided, for example, into REM and NREM states. However, zebrafish are known to have a regulated daytime circadian rhythm. Their sleep state is characterized by periods of inactivity accompanied by an increase in arousal threshold, preference for resting place, and the "rebound sleep effect" phenomenon, which causes an increased slow-wave activity after a forced waking period. In addition, drugs known to modulate sleep, such as melatonin, nootropics, and nicotine, have been tested in zebrafish. In this review, we discuss the use of zebrafish as a model to investigate sleep mechanisms and their regulation, demonstrating this species as a promising model for sleep research.

Abstract
Studies indicate that burnout rates among obstetricians-gynecologists range from 40% to more than 75%, which is in the middle to upper one-third of medical specialties. Symptoms range from feelings of underappreciation and unresolved fatigue, to cynicism, depression, physical symptoms, and illness. Burnout is associated with poor job satisfaction, questioning career choices, and dropping out of practice, impacting workforce concerns and patient access. Awareness of the symptoms and some simple stress and fatigue reduction techniques can decrease the risk of being trapped in the downward spiral of burnout. Successful interventions range from more sleep, to hobbies and vacations, to skilled counseling.

Abstract
Background The 2019 coronavirus disease (COVID-19) pandemic is a public health emergency of international concern and poses a challenge to the mental health and sleep quality of front-line medical staff (FMS). The aim of this study was to investigate the sleep quality of FMS during the COVID-19 outbreak in China and analyze the relationship between mental health and sleep quality of FMS. Methods From February 24, 2020 to March 22, 2020, a cross-sectional study was performed with 543 FMS from a medical center in Western China. A self-reported questionnaire was used to collect data anonymously. The following tests were used: The Self-Rating Anxiety Scale (SAS) for symptoms of anxiety, the Beck Depression Inventory (BDI) for depressive symptoms, and the Pittsburgh Sleep Quality Index (PSQI) for sleep quality assessment. Results Of the 543 FMS, 216 (39.8%) were classified as subjects with poor sleep quality. Anxiety (P<0.001), depression (P<0.001), and the prevalence of those divorced or widowed (P<0.05) were more common in FMS with poor sleep quality than in participants with good sleep quality. The FMS exhibiting co-occurrence of anxiety and depression were associated with worse scores on sleep quality than those medical staff in the other three groups/categories. The difference in sleep quality between the FMS with only depression and the FMS experiencing co-occurrence of anxiety and depression was statistically significant (P<0.05). However, there was no significant difference in sleep quality between the FMS experiencing only anxiety and the FMS with co-occurrence of anxiety and depression (P > 0.05). Conclusions During the COVID-19 pandemic, there was a noteworthy increase in the prevalence of negative emotions and sentiments among the medical staff, along with poor overall sleep quality. We anticipate that this study can stimulate more research into the mental state of FMS during outbreaks and other public health emergencies. In addition, particular attention must be paid to enhance the sleep quality of FMS, along with better planning and support for FMS who are continuously exposed to the existing viral epidemic by virtue of the nature of their profession.

Abstract
PURPOSE To determine the prevalence of sleep-related disorders, poor sleeping, and factors associated with poor sleep quality among inhabitants of Parakou, Benin. METHODS This was a cross-sectional study conducted from April-August 2018 on 930 randomly selected adults (age ≥ 18 years). Using the Pittsburg Sleep Quality Index, the Insomnia Severity Index, and the Epworth Sleepiness Scale, subjects were questioned on their sleep, on parasomnias, and on movement-related sleep disorders. RESULTS Overall, the prevalence of insomnia was 22% (95% CI, 19.1-24.4) and severe insomnia was 0.8%. The prevalence of excessive daytime sleepiness was 15% (95% CI, 12.5-17.0). Daily nightmares (2%) and rhythmic movements (6%) were those most commonly reported among parasomnias and movement-related sleep disorders. No major differences were found between men and women. The prevalence of poor sleeping (PSQI > 5) was 39% (95%CI, 36.3-42.5). Adjusted analyses showed a higher risk of poor sleeping in those aged 45-54 years (aOR = 1.78, p = 0.032) or ≥ 55 years (aOR = 3.61, p < 0.001), those overweight or obese (aOR = 1.53, p = 0.007), those underweight (aOR = 2.90, p = 0.030), and among females (aOR = 1.84, p < 0.001). Being divorced was associated with a lower risk of poor sleeping (aOR = 0.18, p = 0.036). Poor sleepers were more commonly found among those who had excessive daytime sleepiness (65% versus 36%, p < 0.001) and insomnia (86% versus 27%, p < 0.001). CONCLUSION Sleep-related disorders were common in Parakou city, Benin, with four out of ten persons having poor sleep quality. There is a need to improve the management of sleep-related disorders and promote better sleep practices for the community.

Abstract
BACKGROUD/OBJECTIVES Data regarding the effects of poly-γ-glutamic acid (γ-PGA) on sleep status are limited. This study aimed to test whether γ-PGA and vitamin B6 (VitB6) supplements improve sleep duration and quality. SUBJECTS/METHODS A factorial randomized, double-blinded, placebo-controlled crossover study included 47 adults (25 men and 22 women) who were free of chronic disease. Stratified randomized allocation considered age and gender for three interventions, group A (supplementation with γ-PGA 600 mg; n = 16), group B (supplementation with VitB6 100 mg; n = 14), and group C (dual supplementation of both γ-PGA 600 mg and VitB6 100 mg; n = 17). Participants underwent a 1-mon intervention period, followed by a 1-mon washout period, and then a second 1-mon intervention period. Differences (mean ± SD) in nighttime sleep status before and after supplementation were compared between the placebo and intervention groups using nonparametric tests. RESULTS Significant changes in sleep duration (0.27 ± 0.98 h, P < 0.05) and the Pittsburgh Sleep Quality Index global score (−0.52 ± 1.58, P < 0.05) indicating improved sleep status were observed in the intervention compared with the placebo of group C while no significant changes were observed in groups A and B. No statistical significance was detected between the intervention and the placebo; however, there was a greater increase in the group C intervention (4.59 ± 38.5 ng/mL) in serum serotonin concentrations than the groups A and B interventions. No side effects were observed. CONCLUSIONS On the basis of these findings, the dual supplementation of γ-PGA and VitB6 may be effective as functional food components to improve nighttime sleep status.

Abstract
Caffeine is a common stimulant widely existed in food and has stimulatory effects on the central nervous system, shift-work individuals often rely on caffeine to maintain attention and keep awake. Although sleep deprivation (SD) is widely considered as an independent risk factor for cognition retardations, however, little is well understood about the synergistic role of caffeine dosage and SD for cognitive performance. This research intended to investigate the underlying molecular mechanism of varying caffeine doses on cognitive function after sleep deprivation. The results revealed that SD attenuated the cognitive dysfunction, associated with ultrastructure damage and pyramidal neuron loss in the hippocampus, decreased in the level of VIP and AVP. SD also significantly accelerated the neuropeptide-associated apoptosis in the hippocampus, which may modulate via the cAMP-PKA-CREB signal path axis and activation of the downstream apoptosis genes. Additionally, the data indicated that low-dose caffeine (LC) contributed to cognitive enhancement, and high-dose caffeine (HC) aggravated cognitive impairment by modulating hippocampal neuronal apoptosis. Our studies suggest that caffeine, particularly in high dosage, may be a potential factor to influence the neurocognitive outcome caused by sleep loss, and the appropriate amount of caffeine ingested after sleep deprivation deserves serious consideration.

Abstract
The fear and uncertainty caused by the coronavirus disease 2019 (COVID-19) pandemic, threats to survival are one of the main problems of everyday life; however, mental health care must also be considered a priority. During social isolation also called self-quarantine, the restricted mobility and social contact, concern about financial resources and availability of supplies, fear of infection, questions about the duration of self-quarantine, cause anxiety, depression, stress, insomnia and reduced the quality and quantity of sleep, that may present a greater risk to the health of the general population. Sleep disorders are increasingly becoming a major health issue in modern society, and are influenced by retinal stimulation by electronic devices, as well extended and/or night shift-work, which may aggravate the systemic and lung inflammation during viral infections. Sleep disorders can induce pro-inflammatory states and be harmful during the COVID-19 pandemic. The possible interactions between many drugs used to treat COVID-19, and those used to treat sleep disorders are unknown, mostly due to the lack of a standard protocol to treat these patients. Insufficient sleep or irregular sleep-wake cycles may impair health, immune system, induce pro-inflammation state, and may lead to increased vulnerability to viral infections, involving inflammatory and oxidative/antioxidant imbalance. In this sense, obstructive sleep apnea has been associated with recognized COVID-19 risk comorbidities and considered a risk factor for COVID-19. During the COVID-19 pandemic, health care cannot stop, and telemedicine has presented itself as an alternative method of delivering services. When a face-to-face visit is mandatory, or in locations with minimal community transmission where sleep centers have resumed activities, it is important that the sleep center facilities are properly prepared to receive the patients during the COVID-19 pandemic, and follow all relevant safety rules. In this work we gathered a group of researchers, specialists in aspects related to chronobiology, sleep, sleep disorders, and the immune system. Thus, we conducted a narrative review in order to address the relationship between COVID-19 and sleep, as well as its immunological aspects and strategies that may be applied in order to mitigate the harmful effects on health that affects everyone during the pandemic.

Intraperitoneal injection of ginkgolide B, a major active compound of Ginkgo biloba, dose-dependently increases the amount of wake and decreases non-rapid eye movement sleep in C57BL/6 mice. Neurosci Lett 2020; 722:134832. [PMID: 32050100 DOI: 10.1016/j.neulet.2020.134832] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2019] [Revised: 02/06/2020] [Accepted: 02/07/2020] [Indexed: 12/22/2022]
Abstract
The terpene lactones of Ginkgo biloba extract, namely ginkgolides (A, B, and C) and bilobalide, possess antioxidant, anti-inflammatory, and neuroprotective effects. They are widely prescribed for the treatment of cerebral dysfunctions and neurological impairments. In addition, they demonstrate antagonistic action at the gamma-aminobutyric acid type A and glycine receptors, which are members of the ligand-gated ion channel superfamily. In the present study, the effects of ginkgolides (A, B, and C) and bilobalide on sleep in C57BL/6 mice were investigated. Ginkgolide B was found to dose-dependently increase the amount of wake and decrease that of non-rapid eye movement sleep without changes in the electroencephalography power density of each sleep/wake stage, core body temperature and locomotor activity for the first 6 h after intraperitoneal injection. Of note, the amount of wake after injection of 5 mg/kg of ginkgolide B showed a significant increase (14.9 %) compared with that of vehicle (P = 0.005). In contrast, there were no significant differences in the amount of sleep, core body temperature, and locomotor activity in the mice injected with ginkgolide A and C. Bilobalide briefly induced a decrease in locomotor activity but did not exert significant effects on the amounts of sleep and wake. The modes of action of the wake-enhancing effects of ginkgolide B are unknown. However, it may act through the antagonism of gamma-aminobutyric acid type A and glycine receptors because it is established that these inhibitory amino acids mediate sleep and sleep-related physiology. It is of interest to further evaluate the stimulant and awaking actions of ginkgolide B on the central nervous system in clinical and basic research studies.

Abstract
OBJECTIVES It has been reported that South Korea ranked as one of the longest-working nations among OECD countries. This study sought to examine the association between long working hours and musculoskeletal pain among Korean medical residents. METHODS We analyzed a cross-sectional survey of 1,077 medical residents in South Korea. Working hours per week were categorized as follows: <60, 60-79, 80-99, and ≥100. Musculoskeletal pains (ie, upper limb, lower limb, and low back pain) over the past 3 months were categorized into three groups: no pain, pain without interfering with work, and pain interfering with work. Multinomial logistic regression was used to examine the association between long working hours and musculoskeletal pains after adjusting for covariates. RESULTS We found that the average working hours of medical resident was 85.6 hours per week in South Korea. Compared to the medical residents working <60 hours, those working ≥100 hours per week were more likely to have upper limb pain (PR: 1.77, 95% CI: 1.37, 2.30) interfering with work or low back pain (PR: 2.15, 95% CI: 1.51, 3.06) interfering with work, whereas no statistically significant association was observed in the analysis of lower limb pain. CONCLUSIONS This study suggests that extremely long working hours are associated with upper limb and low back pain interfering with their work among Korean medical residents.

Abstract
Background Sleep deprivation (SD) is common in humans, and sleep loss has a significant influence on health and produces related diseases. Orexin-A has been demonstrated to play a role in physiological processes, including feeding, sleep/wake cycle, and energy metabolism. The aim of this study was to investigate the effect of SD on rats and to define the underlying mechanism. Material/Methods We constructed an SD rat model. The Morris water maze test was used to assess rat learning and memory. Imaging of hippocampus and hippocampal tissue in rats were captured by magnetic resonance imaging or electron microscopy. We used the CCK-8 kit to assess cell viability. The level of protein was measured using Western blot analysis, and qRT-PCR was used to evaluate mRNA level. Results SD rats had poorer learning and memory and had damage to the hippocampus. SD resulted in shrinkage of hippocampal volume and encephalocele size. SD increased the expression of Orexin-A, OX1R, OX2R, and PARP-1, and decreased the expression of ERK1/2 and p-ERK1/2. Orexin-A (0–10 μM) improved neuron viability, whereas orexin-A (10–100 μM) attenuated neuron viability. SB334867 treatment reduced the viability of neurons treated with orexin-A. NU1025 treatment increased cell viability, especially in neurons treated with orexin-A. SB334867 treatment decreased the p-ERK1/2 levels in neurons treated with orexin-A. NU1025 increased the expression of p-ERK1/2 in neurons treated with orexin-A. Conclusions SD decreases learning and memory through damage to the hippocampus. Higher concentrations of orexin-A had a major negative effect on hippocampal neurons via OX1R and PARP-1 through inhibition of the ERK1/2 signaling pathway.

Abstract
BACKGROUND Acute and chronic sleep deprivation are significantly associated with depressive symptoms and are thought to be contributors to the development of burnout. In-house call inherently includes frequent periods of disrupted sleep and is common among acute care surgeons. The relationship between in-house call and sleep deprivation among acute care surgeons has not been previously studied. The goal of this study was to determine prevalence and patterns of sleep deprivation in acute care surgeons. STUDY DESIGN A prospective study of acute care surgeons with in-house call responsibilities from 2 level I trauma centers was performed. Participants wore a sleep-tracking device continuously over a 3-month period. Data collected included age, sex, schedule of in-house call, hours and pattern of each sleep stage (light, slow wave, and rapid eye movement [REM]), and total hours of sleep. Sleep patterns were analyzed for each night, excluding in-house call, and categorized as normal, acute sleep deprivation, or chronic sleep deprivation. RESULTS There were 1,421 nights recorded among 17 acute care surgeons (35.3% female; ages 37 to 65 years, mean 45.5 years). Excluding in-house call, the average amount of sleep was 6.54 hours, with 64.8% of sleep patterns categorized as acute sleep deprivation or chronic sleep deprivation. Average amount of sleep was significantly higher on post-call day 1 (6.96 hours, p = 0.0016), but decreased significantly on post-call day 2 (6.33 hours, p = 0.0006). Sleep patterns with acute and chronic sleep deprivation peaked on post-call day 2, and returned to baseline on post-call day 3 (p = 0.046). CONCLUSIONS Sleep patterns consistent with acute and chronic sleep deprivation are common among acute care surgeons and worsen on post-call day 2. Baseline sleep patterns were not recovered until post-call day 3. Future study is needed to identify factors that affect physiologic recovery after in-house call and further elucidate the relationship between sleep deprivation and burnout.

Abstract
The use of mobile devices and applications (apps) to monitor or assist in health behaviors is rapidly expanding in many areas of society. Clinicians desire evidence-based app recommendations for their clients to increase self-care and wellness management in such areas as mindfulness, weight loss and activity tracking, glycemic control, and consumer medication information. Given the constant influx of new apps into the major app repositories, clinicians need to be able to ensure the quality of information and interaction that occurs within the mobile health (mHealth) marketplace. The Mobile Application Rating Scale (MARS) and the user version of the scale are valid and reliable instruments used to examine the engagement, functionality, aesthetics, and quality of information in mHealth apps. MARS-rated apps can be readily available resources for busy clinicians to make app suggestions to assist clients on a variety of topics that promote improved outcomes. This article reviews the MARS instrument and utilization of the instrument by clinicians and summarizes several primary care and wellness apps that have been evaluated using this tool.

Abstract
INTRODUCTION Excessive daytime sleepiness is defined as difficulty maintaining wakefulness and alertness during normal waking hours. Excessive daytime sleepiness can lead to clinical errors in health care workers and is associated with dangerous driving. Little is known about the level of daytime sleepiness in midwives in the United States. The purposes of this study, conducted by the American College of Nurse-Midwives (ACNM) Sleep and Safety Taskforce, were first to identify the sleepiness level of US certified nurse-midwives (CNMs) and certified midwives (CMs) by calculating Epworth Sleepiness Scale scores for CNM/CMs in full-scope practice, and then to determine factors that significantly contribute to elevated Epworth Sleepiness Scale scores (>10). METHODS Participants in this descriptive, correlational survey study were active ACNM members in full-scope midwifery practice. Descriptive statistics, bivariate analysis, and logistic regression were used for data analysis. Surveys were emailed to all active members of ACNM (N = 4358). RESULTS A total of 753 (17.3%) survey responses were returned, of which 639 (14.7%) were eligible for analysis. Within this group, 639 (84.9%) self-identified as being in full-scope midwifery practice, and one-fourth (n = 164; 25.7%) had elevated Epworth Sleepiness Scale scores. Duration of work shifts was the only variable found to significantly contribute to differences in Epworth Sleepiness Scale scores, with midwives working shifts longer than 12 hours having higher rates of excessive daytime sleepiness compared with midwives who worked shifts of 12 hours or less. DISCUSSION Midwives, midwifery services, and maternity care centers can work together to ensure that clinicians obtain adequate sleep. Reducing excessive sleepiness will contribute to increased safety for midwives, women, newborns, and the general public.

Abstract
To maximize the performance of an athlete, a team of experts work together to ensure each athlete achieves the maximal benefit from their prescribed exercise conditioning programs. In addition to the exercise specialists, the athlete’s team frequently includes psychologists (who address performance anxiety, stress, and depression), counselors (who address smoking cessation, reduction or elimination of alcohol consumption if necessary, weight optimization, and optimal sleep), and nutritionists (who address optimal nutrition and body mass attributes). Such a collaborative approach has become standard practice for athletes aiming to excel in their sports. Despite unequivocal and compelling evidence, this paradigm has only weakly been transferred to the needs of patients participating in rehabilitation programs. These individuals, like the athlete, also need to achieve their highest level of functional performance and recovery for carrying out their activities of daily living, managing the needs of their families, and often returning to work. This article reviews the evidence-based literature and the implications of this multifaceted approach in rehabilitation programs. The augmented benefits to exercise training and conditioning (prescriptive activity/exercise and less sitting) along with their ‘effect sizes’ are described in the rehabilitation context, in conjunction with smoking cessation, reduced harmful alcohol consumption, optimal nutrition, optimal body mass, manageable stress, and optimal sleep. These factors can be viewed as physical performance enhancers both in individuals participating in rehabilitation whose aim is maximal performance and recovery and in athletes aiming for maximal performance in their sports. Thus, without targeted attention to these lifestyle factors, rehabilitation outcomes cannot be maximized. The evidence presented in this article has implications for health professionals including physical therapists and others who are practicing in rehabilitation settings and those working with individuals in need in the community.

Abstract
The Barker Hypothesis states change to the maternal environment may have significant impacts on fetal development, setting the stage for adult disease to occur. The development of the maternofetal vasculature during implantation and maintenance during pregnancy is extremely precise, yet dynamic. Delays or dysfunction in the orchestration of anatomical remodeling, maintenance of blood pressure, or responsiveness to metabolic demand may have severe consequences to the developing fetus. While these intermissions may not be fatal to the developing fetus, an interruption, reduction, or an inability to meet fetal demand of blood flow during crucial stages of development may predispose young to disease later in life. Maternal inability to meet fetal demand can be attributed to improper placental development and vascular support through morphological change or physiological function will significantly limit nutrient delivery and waste exchange to the developing fetus. Therefore, we present an overview of the uteroplacental vascular network, maternal cardiovascular adaptations that occur during pregnancy, placental blood flow, and common maternal comorbidities and/or exposures that may perturb maternal homeostasis and affect fetal development. Overall, we examine uterine microvasculature pathophysiology contributing to a hostile gestational environment and fetal predisposition to disease as it relates to the Barker Hypothesis.

Abstract
Disruption of the monoaminergic system, e.g. by sleep deprivation (SD), seems to promote certain diseases. Assessment of monoamine levels over the circadian cycle, during different sleep stages and during SD is instrumental to understand the molecular dynamics during and after SD. To provide a complete overview of all available evidence, we performed a systematic review. A comprehensive search was performed for microdialysis and certain monoamines (dopamine, serotonin, noradrenaline, adrenaline), certain monoamine metabolites (3,4-dihydroxyphenylacetic acid (DOPAC), 5-hydroxyindoleacetic acid (5-HIAA)) and a precursor (5-hydroxytryptophan (5-HTP)) in PubMed and EMBASE. After screening of the search results by two independent reviewers, 94 publications were included. All results were tabulated and described qualitatively. Network-meta analyses (NMAs) were performed to compare noradrenaline and serotonin concentrations between sleep stages. We further present experimental monoamine data from the medial prefrontal cortical (mPFC). Monoamine levels varied with brain region and circadian cycle. During sleep, monoamine levels generally decreased compared to wake. These qualitative observations were supported by the NMAs: noradrenaline and serotonin levels decreased from wakefulness to slow wave sleep and decreased further during Rapid Eye Movement sleep. In contrast, monoamine levels generally increased during SD, and sometimes remained high even during subsequent recovery. Decreases during or after SD were only reported for serotonin. In our experiment, SD did not affect any of the mPFC monoamine levels. Concluding, monoamine levels vary over the light-dark cycle and between sleep stages. SD modifies the patterns, with effects sometimes lasting beyond the SD period.

Abstract
Many studies have shown the effects of sleep deprivation in several aspects of health and disease. However, little is known about how mitochondrial bioenergetics function is affected under this condition. To clarify this, we developed a simple model of short-term sleep deprivation, in which fruit-flies were submitted to a nocturnal light condition and then mitochondrial parameters were assessed by high resolution respirometry (HRR). Exposure of flies to constant light was able to alter sleep patterns, causing locomotor deficits, increasing ROS production and lipid peroxidation, affecting mitochondrial activity, antioxidant defense enzymes and caspase activity. HRR analysis showed that sleep deprivation affected mitochondrial bioenergetics capacity, decreasing respiration at oxidative phosphorylation (OXPHOS) and electron transport system (ETS). In addition, the expression of genes involved in the response to oxidative stress and apoptosis were increased. Thus, our results suggest a connection between sleep deprivation and oxidative stress, pointing to mitochondria as a possible target of this relationship.

Abstract
It is estimated that 40% to 75% of obstetricians and gynecologists currently suffer from professional burnout, making the lifetime risk a virtual certainty. Although these statistics make for a dismal view of the profession, if the causes and symptoms can be identified simple steps can be implemented to reverse the threat. With a little care, the enjoyment of practice can be restored and the sense of reward and the value of service can be returned.

Abstract
The burden and impact of sleep deprivation on both patient care and on the health of interventional cardiologists is not well understood. Due to the nature of emergent procedures occurring in the cardiac catheterization laboratory, interventionalists are prone to suffer from acute and/or chronic sleep deprivation. Sleep deprivation has been associated with numerous adverse effects, such as impaired performance, cognitive deficits, reduced psychomotor vigilance, and workplace errors and injuries, among many others. Although sleep deprivation has been linked to more errors in trainees, there is paucity of data addressing outcomes in interventional cardiology. The purpose of this overview is to explore the possible impact of sleep deprivation on interventional cardiology in relation to patient care and physician health, and examine potential approaches to this issue.

Abstract
PURPOSE Fatigue jeopardizes seafarer's health and safety. Thus, knowledge on determinants of fatigue is of great importance to facilitate its prevention. However, a systematic analysis and quality assessment of all empirical evidence specifically for fatigue are still lacking. The aim of the present article was therefore to systematically detect, analyze and assess the quality of this evidence. METHODS Systematic searches in ten databases were performed. Searches considered articles published in scholarly journals from 1980 to April 15, 2016. Nineteen out of 98 eligible studies were included in the review. The main reason for exclusion was fatigue not being the outcome variable. RESULTS Most evidence was available for work time-related factors suggesting that working nights was most fatiguing, that fatigue levels were higher toward the end of watch or shift, and that the 6-h on-6-h off watch system was the most fatiguing. Specific work demands and particularly the psychosocial work environment have received little attention, but preliminary evidence suggests that stress may be an important factor. A majority of 12 studies were evaluated as potentially having a high risk of bias. CONCLUSIONS Realistic countermeasures ought to be established, e.g., in terms of shared or split night shifts. As internal as well as external validity of many study findings was limited, the range of factors investigated was insufficient and few studies investigated more complex interactions between different factors, knowledge derived from studies of high methodological quality investigating different factors, including psychosocial work environments, are needed to support future preventive programs.
