Longer-term Effect of Physical Activity Intervention on Sleep Quality: A Secondary Analysis of Cluster Randomized Controlled Trial.

To examine the longer-term effect of physical activity (PA) intervention on sleep quality and whether the effect was heterogeneous between daytime nappers and non-nappers. This study was a secondary analysis of a cluster randomized controlled trial in China. Eight villages were randomized 1:1 to intervention or control group. The intervention group received an 8-week PA intervention, while the control group did not. The primary outcome of this study was the change in the Pittsburgh Sleep Quality Index (PSQI) global score at 24 months. The 511 participants had a mean age of 70.94 years (SD 5.73) and 55.6% were female. The intervention showed improvements in the PSQI global score at 8 weeks (adjusted mean difference -1.05; P=0.002), and the effect diminished at 24 months (-0.64; P=0.06). There were statistically significant improvements in the PSQI global score for daytime nappers, but not for non-nappers at 8 weeks (adjusted mean difference -0.98; P=0.01 vs -1.27; P=0.05), 12 months (-0.86; P=0.03 vs -0.84; P=0.21), and 24 months (-0.80; P=0.04 vs -0.14; P=0.84), although these improvements were below the minimum detectible level of the PSQI which is 1 point. The 8-week PA intervention was effective in improving sleep quality, while the effect was diminished and below the minimum detectible level of the PSQI which is 1 point after 24 months. The effect of PA intervention on sleep quality was more pronounced in daytime nappers. Additional interventions (e.g., focusing on multiple behavioral interventions such as PA and healthy diet) are needed to maintain the beneficial effect of PA on sleep quality in the general older populations. Further research is required to confirm the mechanisms of the effect of napping and develop tailored interventions.

Fatigue and sleep quality improvement through complete decongestive therapy in postmastectomy lymphedema: An investigative analysis

ObjectiveTo evaluate the effects of complete decongestive therapy (CDT) on cancer-related fatigue, sleep quality, and lymphedema-specific quality of life using validated and reliable questionnaires in cancer patients being commendable.Material and methodsThis prospective study includes 94 patients who had postmastectomy lymphedema syndrome. The demographic characteristics of the patients were recorded. The participants’ stages of lymphedema (The International Society of Lymphology), Hirai Cancer Fatigue Scale (HCFS) score, Pittsburgh Sleep Quality Index (PSQI) Global score, lymphedema-specific quality of life questionnaire (LYMQOL-ARM) score, and Global health status were recorded before and after CDT.ResultsThe mean age of the patients was 58.49 ± 10.96 years. Strong correlations were found between the severity of edema and global health status. There was a significant positive relationship between the HCFS score, PSQI Global score, LYMQOL-ARM score, and CDT. After decongestive physiotherapy, the majority of the lymphedema stages were downstaging (p < 0.05), respectively. There was also a trend toward improvement in general well-being (p < 0.05).ConclusionCancer-related fatigue and sleep disturbance can persist for years after surgery in women with breast cancer. This can negatively affect the patient physically, socially and cognitively. Our study, which is the first study to investigate the HCFS score in postmastectomy patients and the relationship between PSQI Global score and CDT. The findings identify the risk factors that affect these outcomes in women with lymphedema and can provide valuable insights for targeted interventions and improved patient care.

Sleep Quality Moderates the Associations between Cardiorespiratory Fitness and Hippocampal and Entorhinal Volume in Middle-Aged and Older Adults.

As individuals age, the entorhinal cortex (ERC) and hippocampus-crucial structures for memory-tend to atrophy, with related cognitive decline. Simultaneously, lifestyle factors that can be modified, such as exercise and sleep, have been separately linked to slowing of brain atrophy and functional decline. However, the synergistic impact of fitness and sleep on susceptible brain structures in aging adults remains uncertain. We examined both independent and interactive associations of fitness and subjective sleep quality with regard to ERC thickness and hippocampal volume in 598 middle-aged and older adults from the Human Connectome Lifespan Aging Project. Cardiorespiratory fitness was assessed using the 2-min walk test, whereas subjective sleep quality was measured with the continuous Pittsburgh Sleep Quality Index global score. High-resolution structural magnetic resonance imaging was used to examine mean ERC thickness and bilateral hippocampal volume. Through multiple linear regression analyses, we investigated the moderating effects of subjective sleep quality on the association between fitness and brain structure, accounting for age, sex, education, body mass index, gait speed, and subjective physical activity. We found that greater cardiorespiratory fitness, but not subjective sleep quality, was positively associated with bilateral hippocampal volume and ERC thickness. Notably, significant interaction effects suggest that poor subjective sleep quality was associated with a weaker association between fitness and both hippocampal volume and ERC thickness. Findings suggest the potential importance of both cardiorespiratory fitness and subjective sleep quality in preserving critical, age-vulnerable brain structures. Interventions targeting brain health should consider potential combined effects of sleep and fitness on brain health.

A cross-sectional study of sleep quality in urban and rural adolescents with reference to their digital exposure

Abstract Background: With the widespread use of digital devices and increased screen time among adolescents, concerns have arisen regarding its potential impact on sleep quality. This study aims to investigate the correlation between excessive screen time and Pittsburgh Sleep Quality Index (PSQI) global scores in adolescents. Materials and Methods: A cross-sectional study was conducted among 167 adolescents aged 10–19 years residing in rural and urban areas. Participants completed self-report questionnaires evaluating their screen time habits and sleep quality using the PSQI. Excessive screen time was defined as more than 2 h per day of exposure to digital screens, and an abnormal PSQI global score was defined as more than 5. Statistical analyses, including unpaired t test, Spearman’s correlation, and chi-square test, were employed to examine the association between excessive screen time and PSQI global scores. Results: The results revealed a significant positive correlation between excessive screen time and abnormal PSQI scores in adolescents (r = 0.623, P &lt; 0.001). Adolescents reporting excessive screen time were significantly more prone to abnormal PSQI scores compared to those with lower screen time (P &lt; 0.0001, t = 9.63, degree of freedom = 165). Conclusion: This study highlights a correlation between excessive screen time and abnormal sleep quality in adolescents, as assessed by the PSQI. These findings underscore the importance of promoting healthy screen time habits among adolescents to mitigate potential adverse effects on their sleep quality and overall health. Further research is needed to explore the mechanisms underlying this relationship and to develop effective interventions to address this issue.

Associations between the burdens of comorbid sleep problems, central sensitization, and headache-related disability in patients with migraine.

Sleep disturbances are common in migraine patients and affect quality of life. Central sensitization (CS) is likely to play a role in the increased severity and chronicity of migraine. We hypothesized that the number of comorbid sleep problems would affect headache-related disability through the effects of central sensitization (CS). We performed a cross-sectional study including 215 consecutive patients with migraine. Insomnia was defined as a Pittsburgh Sleep Quality Index (PSQI) global score greater than 5. Probable REM sleep behavior disorder (pRBD) was defined as an RBD screening score of 5 or greater. Excessive daytime sleepiness (EDS) was defined as an Epworth Sleepiness Scale score of 10 or higher. Suspected sleep apnea (SA) was defined as patients with snoring or sleep apnea witnessed 3 or more nights a week. CS was assessed by the Central Sensitization Inventory (CSI). Restless legs syndrome, insomnia, EDS, SA and pRBD were observed in 25.6%, 71.6%, 34.4%, 10.2%, and 21.4%, respectively, of the patients. At least one sleep problem was present in 87.0% of the patients. According to the results of the multinomial logistic regression analysis with no sleep problems as a reference, after we corrected for adjustment factors, the Migraine Disability Assessment (MIDAS) score significantly increased when three or more comorbid sleep problems were present. According to our mediation analysis, an increased number of sleep problems had a direct effect on the MIDAS score after we adjusted for other variables, and the CSI score was indirectly involved in this association. The present study showed an association between migraine-related disability and the burden of multiple sleep problems, which was partially mediated by CS.

The moderating role of circadian gene polymorphisms in the relationship between sleep disturbance and circulating lymphocyte subsets in colorectal cancer patients

AimWe investigated the impact of sleep disturbance on immune status in colorectal cancer (CRC) patients with consideration of the moderating role of circadian clock gene polymorphisms. MethodsA prospective longitudinal study design was used to collect information regarding sleep disturbance. Blood samples for immunologic assays were obtained the day before the first (baseline) and last cycles of 5-fluorouracil, leucovorin, and oxaliplatin (FOLFOX) chemotherapy. Clinical sleep disturbance was compared between the two-time points using the Pittsburgh Sleep Quality Index (PSQI) global score. We analysed single-nucleotide polymorphisms in rs2278749, rs3749474, rs2291738, rs17031614, and rs2287161. The dependent variables included changes in the percentages of CD4+, CD8+, CD19+, and CD16/56+ lymphocytes between the two-time points. The results were analysed using moderated regression analysis; the p-values were adjusted using the false discovery rate. ResultsAmong the 104 patients, no significant dyadic associations were observed between changes in lymphocyte percentages and the PSQI global score. However, the moderated regression analysis revealed five significant associations (rs2287161 with CD8+, rs2278749 and rs2291738 with CD19+, and rs17031614 with CD4+ and CD16/56+ lymphocytes). The inclusion of each interaction resulted in a significant increase (5.7–10.7%) in the variance explained by changes in lymphocyte percentage. ConclusionPatients with specific circadian gene allele types may be more susceptible to immune dysregulation when experiencing sleep disturbances. Considering that sleep disturbance is a modifiable factor that can impact immune regulation, it is essential to prioritise the management of sleep disturbances in CRC patients receiving FOLFOX chemotherapy.

Sleep Quality and Day‐to‐Day Variability: Relation to Alzheimer’s pathology in Cognitively Unimpaired Older Adults At‐Risk of AD Dementia

AbstractBackgroundIncreasing evidence suggests a link between sleep and late‐life Alzheimer disease’s (AD) pathology. We investigated whether sleep degradation might be accompanied by faster AD pathology accumulation and/or whether early AD pathologic changes might be accompanied by sleep changes before the onset of cognitive symptoms.MethodWe investigated 228 PREVENT‐AD participants with available sleep data who underwent Aβ, [18F] NAV‐4694, and tau,[18F] Flortaucipir, positron emission tomography (PET). Longitudinal subjective sleep quality data were available for 191 participants (follow‐up:1.03±0.19y), longitudinal objective sleep data measured with actigraphy was available for 152 participants (follow‐up:2.5±1.24y), and longitudinal PET scans were available for 104 participants (follow‐up:4.3±0.24y). We assessed sleep quality using the Pittsburgh sleep quality index (PSQI) global score along with 7‐day actigraphy to indicate sleep duration, efficiency, and fragmentation index. Daily variation in sleep was measured using cross‐sectional and longitudinal standard deviations across the 7 days of actigraphy. Linear mixed effect models tested for longitudinal association of baseline sleep measures with PET outcomes over time. We also examined whether an increase in PET AD tracer uptake predicted changes in sleep quality and day‐to‐day variability. Every model controlled for age and sex.ResultWe found no association between sleep measures and Aβ PET.Higher baseline PSQI scores were associated with higher levels of tau over time (p = 0.004, R2 = 0.034, 𝛽 = 0.007, Fig.1, A). Higher baseline variability of sleep duration and fragmentation index were also associated with higher levels of tau longitudinally (p = 0.001, R2 = 0.05, 𝛽 = 0.001, Fig.1, B; p = 0.029, R2 = 0.022, 𝛽 = 0.01; Fig.1, C). Furthermore, increased tau at baseline was associated with lower sleep quality (p = 0.006, R2 = 0.026, 𝛽 = 4.12, Fig.2, A), and with higher sleep duration variability over time (p = 0.004, R2 = 0.06, 𝛽 = 61.56, Fig.1, B.)ConclusionPoor sleep quality and higher day‐to‐day sleep variability in older age could contribute to faster rate of tau pathology accumulation, which could in turn disrupt sleep further. Targeting sleep disturbances may therefore serve in delaying tau burden and slowing down disease progression.

58 Sex Differences in the Relationship Between Sleep Disruption and Depressive Symptoms During Acute and Chronic Stages of Mild Traumatic Brain Injury (mTBI)

Objective:mTBI is trauma to the brain due to a blow or other mechanical force affecting the head. Prior research has established that common symptoms of mTBI include decreased sleep quality and onset/worsening of emotional dysregulation. However, there is little published research investigating how sleep disruption and depressive symptoms are experienced at varying stages of mTBI. We hypothesized that sleep disruption would change with differing time since injury, and that depressive symptoms should accordingly. Additionally, since females tend to have higher rates of depression, we predicted that there would be a significant difference between the sexes at different stages post-mTBI.Participants and Methods:This study included 145 healthy adults, split into six groups, comparing healthy controls consisting of 15 males (Mage=23.67, SD=5.066) and 17 females (Mage=25.35, SD=7.035) to individuals who had mTBI, 41 males (Mage=26.88, SD=8.509) and 72 females (Mage=23.79, SD=6.898) at five points post-mTBI: 2 weeks and 1, 3, 6, and 12 months. The Pittsburgh Sleep Quality Index (PSQI) global score was used to assess individual sleep quality and disturbances; higher scores indicated poorer sleep quality. The Beck Depression Index (BDI-II) was used to assess characteristics and symptoms of depression. We adjusted the score to exclude item 16, which measures changes in sleep. Higher scores indicate more severe depressive symptoms. We conducted a multivariate analysis of variance and Pearson correlation to examine whether there were significant differences in sleep and depression at different stages of mTBI for each sex.Results:We discovered that sleep quality was worse at chronic stages of mTBI (i.e, 12M, p=&lt;.001), than at acute stages (2W, p=.049), and compared to healthy controls. There were also significant differences in depression scores compared to healthy controls at 2W, p=.008, 3M, p=&lt;.001, and 6M, p=.012, but not 12M, p=.313, suggesting that depressive symptoms resolved by 12M in those with mTBI. To explain this, we investigated sex differences, as males tend to experience fewer depressive disorders than females. However, females reported fewer depressive symptoms than males at chronic stages of mTBI. This finding was not statistically significant as females had a Mbdi_total=6.84, SD=7.98 and males had a Mbdi_total=5.38, SD=6.078; still, this could be due to the low statistical power of the study, and with a larger sample size, could produce statistically significant differences between the sexes. Despite this, there is a statistically significant difference in the depression score for females between 2W and 12M post-mTBI (p=.046; effect size of d=.99). Comparatively, males showed no significant divergence between depression and sleep scores.Conclusions:Sleep disruption and depressive symptoms were correlated in individuals with mTBI in both acute and chronic stages; however, at 12M, there was a decrease in this correlation due to females exhibiting fewer depressive symptoms in combination with greater sleep disruption in the chronic phase of mTBI. Further research investigating the relationship between depression and sleep quality by looking at females with a much larger sample size would be helpful in clarifying these associations.

Sleep Quality, Sleep Efficiency, and Perceived Stress after Synchronous Virtual Mindfulness Meditation Sessions for Higher Education Students

This study&lt;strong&gt; &lt;/strong&gt;examined the effects of virtual mindfulness meditation programming on sleep efficiency using wearable tracking devices, as well as effects on sleep quality and perceived stress in higher education students.&lt;strong&gt; &lt;/strong&gt;A one-group, pretest-posttest design with convenience sampling and rolling recruitment over a six-month period resulted in twenty-five participants who completed the study and were included in data analysis. Paired t-tests were used to determine statistical significance for sleep efficiency measured using the Fitbit Inspire 2, Pittsburgh Sleep Quality Index (PSQI) global score, and Perceived Stress Scale (PSS) total scores. Significance was observed in positive outcomes for sleep quality (&lt;em&gt;p&lt;/em&gt; = 0.010) and perceived stress (&lt;em&gt;p&lt;/em&gt; = 0.032). Sleep efficiency resulted in no significant change (&lt;em&gt;p&lt;/em&gt; = 0.063). The synchronous virtual program had a positive effect on the sleep quality and perceived stress; however, the use of wearables should be integrated with caution. Higher education students and professionals at higher education institutions may consider non-pharmacological approaches to treating stress and sleep.

Effect of Nighttime Exercise on Sleep Quality Among the General Population in Riyadh, Saudi Arabia: A Cross-Sectional Study.

Introduction Engaging in physical activity has been proven to have health benefits, with a positive impact on sleep quality. While the timing of exercise plays a significant role in determining its effect on sleep, nighttime exercise still needs to be explored, especially in Saudi Arabia. This study assessed the effect of nighttime exercise on sleep quality among the general population in Riyadh, Saudi Arabia. Methods A cross-sectional study was conducted on people performing physical exercises in the gym, training, and walking places using a self-administered questionnaire evaluating exercising behaviors and sleep quality. Comparisons were performed using the Chi-square test and ANOVA, and p<0.05 was considered for significance. Results We enrolled 385 participants, among whom 53.8% were male, and 47.2% were female. The mean age was 28.2±7.85 years, and mostly aged 25-29 years (24.7%), followed by 20-24 years old (21.3%). Most had university degrees (61.3%) and were also employed(60%). Of all participants, the majority were overweight and obese (61.3%). Most (n=225) participants practiced vigorous physical exercise, and the mean Pittsburgh Sleep Quality Index (PSQI) global score was 7.37±3.49 points. Evening vigorous (r= 0.25, p=0.038) and moderate (r=0.30, p=0.025) physical exercise sessions lasting > 90 min had a significant positive correlation with poor sleep quality (high PSQL score). There was no statistically significant correlation between sleep quality and other variables (p>0.05). Conclusion This study found that participants had poor sleep quality, and lengthy, intense evening exercises had a negative effect on sleep. Incorporating regular exercise tailored to individual preferences and encouraging people to widen the time interval between exercise and bedtime could improve sleep quality.

ASSOCIATION BETWEEN SLEEP QUALITY AND GERIATRIC SYNDROMES IN NURSING HOME RESIDENTS

Background: With aging, an increase is observed in some geriatric syndromes as well as sleep disorders. Objective: The aim of this study is to investigate the relationship between sleep quality and geriatric syndromes (dementia, depression, sarcopenia, malnutrition, and frailty) in nursing home residents. Methods: The participants’ demographic characteristics, comorbid diseases, number of drugs, cognitive performance, mood and nutritional states, sarcopenia and fraility screening tests and sleep quality test were evaluated by two geriatricians. The participants were divided into two groups as good sleep quality and poor sleep quality. Correlation analysis of sleep quality and geriatric and mental functionality tests was performed with Spearman correlation analysis. Results: A total of 104 nursing home residents (34 females, 74 males, aged 61-98) participated in the study. Sleep quality was found to be worse in the elderly between the ages of 75-84, with a higher number of children, using assistive devices, and taking selective serotonin reuptake inhibitors. In addition, in participants with poor sleep quality, SARC-f (strength, assistance with walking, rising from a chair, climbing stairs, and falls) and geriatric depression scale scores were significantly higher. The Pittsburgh Sleep Quality Index global score was negatively associated with total sleep time and positively associated with geriatric depression scale score and SARC-f score. Conclusion: Findings from the present study in relation between poor sleep quality and some geriatric evaluation parameters suggests that there may be a common pathophysiological alteration with aging.

Daily consumption of Lactobacillus gasseri CP2305 improves quality of sleep in adults – A systematic literature review and meta-analysis

The gut-brain axis is one of the proposed interactions between the brain and peripheral intestinal functions; of particular interest is the influence of food components on the gut-brain axis mediated via the gut microbiome. Probiotics and paraprobiotics have been proposed to interact with the intestinal environment and provide health benefits such as improving sleep quality. The aim of this research was to undertake a systematic literature review and meta-analysis to evaluate the current evidence regarding the effects of Lactobacillus gasseri CP2305 on sleep quality for the general population. A systematic literature search was conducted of peer-reviewed articles published up to 04 November 2022. Randomised controlled trials were identified that investigated the effects of Lactobacillus gasseri CP2305 on sleep parameters in adults. Meta-analysis of the change in the Pittsburgh Sleep Quality Index (PSQI) global score was conducted. Quality assessments of individual studies were conducted using the Cochrane Risk of Bias and Health Canada tools. Seven studies were included in the systematic literature review; six studies included data for meta-analysis to quantify the effect of L.gasseri CP2305 on sleep quality. The ingestion of L.gasseri CP2305 resulted in significant improvement in the PSQI global score compared to control (-0.77, 95% CI:-1.37 to-0.16, P=0.01). In the two studies that included electroencephalogram (EEG) data, output was significantly improved for at least half of the measured EEG outcomes after consumption of L.gasseri CP2305. No serious concerns were found in the potential biases of included studies, indirectness of the included evidence, and other methodological issues. The present systematic review and meta-analysis indicates significant improvement in sleep quality of adults with mild to moderate stress as an effect of daily consumption of L.gasseri CP2305. Based on existing evidence, the relationship between L.gasseri CP2305 and enhanced sleep quality is plausible, however further investigations are required to confirm the mechanisms of actions for this effect.

Changes in health and sleep quality after anti-retroviral treatment modification in Japanese people living with HIV

BackgroundAnti-retroviral treatment (ART) modification for treatment simplification is performed in virologically controlled people living with Human Immunodeficiency Virus (PLWH). However, studies on the impact of these stable treatment modifications on health-related quality of life (HRQoL) measured using patient-reported outcomes (PROs) in clinical practice are scarce; this was the focus of this study. MethodsPLWH who visited Teikyo University Hospital between October 2019 and March 2021, and whose ART was changed to a newly recommended single-tablet regimen for treatment simplification, were included in the study. HRQoL and sleep quality were evaluated using the Short-Form (SF) 8 and Pittsburgh Sleep Quality Index (PSQI) global score, respectively, at two time points: before and after treatment modification. Comorbidities, duration of Human Immunodeficiency Virus diagnosis, ART initiation, ART regimens, and blood test data before and after treatment were assessed. The SF-8 was used to calculate the physical component summary (PCS) and mental component summary (MCS) scores. ResultsForty-nine patients (all male) were included into the study. There was no change in the PCS score before and after ART modification. The MCS score significantly improved from 48.50 ± 6.56 to 50.76 ± 4.37 (p = 0.0159). Thirteen patients' ARTs were changed to dolutegravir/lamivudine. Their HRQoL and sleep quality changes were further analyzed. Their MCS and PSQI scores had improved significantly. Thirty patients’ ARTs were changed to bictegravir/tenofovir alafenamide/emtricitabine; however, there were no significant changes in their HRQoL or PSQI score. ConclusionART modification for treatment simplification based on PROs may improve the HRQoL of PLWH.

0174 Patterns of sleep habits and their impact on nighttime sleep quality in college students

Abstract Introduction Poor sleep quality is common in college student. Unhealthy sleep habits (e.g., delayed bedtime, inconsistent sleep routine between schooldays and weekends) could lead to poor sleep quality, which is associated with poor academic performance, mental and physical health. However, little is known about the patterns of sleep habits in terms of timing and consistency and their impact on nighttime sleep quality in college students. Methods This was a cross-sectional anonymous web-based survey to examine sleep in college students. The Classification and Regression Tree (C&amp;RT) was used to identify distinct patterns based on sleep habits including bedtime and wake-up time (usual, schooldays, and weekends), and consistency of bedtime, wake-up time, and duration between schooldays and weekends. The response variable was nighttime sleep quality measured by the Pittsburgh Sleep Quality Index (PSQI) global score. The imputed PSQI global score was used to minimize missing data. Results A total of 439 students participated in this survey, with a response rate at 22%. Four distinct clusters were identified. Both Cluster 1 (37.8%) and Cluster 2 (10.9%) included participants who reported a difference in sleep duration between schooldays and weekends &amp;lt; 1.75 hours, with Cluster 1 reporting a usual bedtime before 1:45AM while Cluster 2 after 1:45AM. Both Cluster 3 (3.4%) and Cluster 4 (47.8%) included participants who reported a difference in sleep duration between schooldays and weekends ≥ 1.75 hours, with Cluster 3 reporting school-day wake-up time before 7AM while Cluster 4 after 7AM. Among the four clusters, participants in Cluster 3 (late riser with inconsistent schooldays-weekends duration) had the worst sleep quality (8.95±3.43), followed by Cluster 2 (late sleeper with consistent schooldays-weekends duration, 6.98±2.79) and Cluster 4 (late riser with inconsistent schooldays-weekends duration, 6.83±2.87). Cluster 1 (“early” sleepers with consistent schooldays-weekends duration) had the best sleep quality among all (5.61±2.54). Conclusion Distinct patterns of sleep timing and consistency can have significant impact on sleep quality, with some habits such as extremely late bedtime and inconsistent sleep duration between schooldays and weekends had the most negative impact. Tailoring interventions targeting these unhealthy sleep habits are needed in promoting sleep in this population. Support (if any) None

Protocol for a randomized controlled trial evaluating the effect of Hibiscus syriacus L. flower extract on sleep quality.

Hibiscus syriacus L. flower (HSF) is a food ingredient commonly used for tea, and previous animal studies have reported its sleep-promoting effect. This study aims to test the potential of HSF extract as functional food that improves sleep in humans. Eighty participants with sleep disturbances who meet the inclusion/exclusion criteria will be enrolled in this study. Since the effect of HSF extract on sleep is considered to be that of a functional food rather than a medicine, participants with severe insomnia will be excluded from the study. The enrolled participants will be randomly assigned to the HSF extract or placebo groups in a 1:1 ratio. The HSF extract and placebo capsules will look identical, and participants, investigators, and outcome assessors will be blinded to the allocation. Four capsules of HSF extract or placebo will be orally administered 30-60 min before bedtime for 4 weeks. The primary outcome of this study will be the change in the Pittsburgh Sleep Quality Index (PSQI) global score from the baseline after 4 weeks. The subjective and objective changes in the participants' sleep will be evaluated using the Insomnia Severity Index (ISI), Epworth Sleep Scale (ESS), sleep diary, and polysomnography (PSG). The occurrence of adverse events will be closely monitored. The results of this trial will provide data on the efficacy and safety of HSF extract in enhancing sleep quality. Based on the results, the potential of HSF extract as a functional food that improves sleep in humans will be evaluated, and the findings of the trial will be submitted to the Korean Ministry of Food and Drug Safety for consideration as a new functional ingredient that may help to improve sleep quality. : Clinical Research Information Service: KCT0007314; Registered 19 May 2022, https://cris.nih.go.kr/cris/search/detailSearch.do/21497.

Sleep quality among psoriasis patients: excluding the immunosuppressive therapy effect

BackgroundPsoriasis is associated with several comorbidities and different psychological disorders including anxiety and depression. Psoriasis may also affect sleep quality and consequently the quality of life. The use of immunosuppressants used in the treatment of psoriasis were also reported to increase insomnia, so the purpose of the study is to assess the quality of sleep and degree of insomnia in patients with psoriasis not on any systemic or immunosuppressive therapy compared to controls and to examine the relation between sleep quality, insomnia with depressive, and anxiety symptoms. One hundred psoriasis cases, not receiving immunosuppressive therapy, and 80 apparently healthy subjects were recruited as controls. We assessed quality of sleep, insomnia and screened for anxiety and depressive symptoms among psoriasis patients and healthy controls; any patient on immunosuppressant therapy was excluded.ResultsQuality of sleep using Pittsburgh Sleep Quality Index, insomnia using Insomnia Severity Index, depression using Beck Depression Inventory, and anxiety using Taylor Anxiety Manifest Scale were statistically significant higher among psoriasis patients than healthy controls all with p value p < 0.001. Depressive symptoms were significantly positively correlated with Pittsburgh Sleep Quality Index (PSQI) global score (p = 0.045) and subjective sleep quality subscale (p = 0.005). Also, BDI scores was significantly positively correlated with insomnia scores as measured by ISI (p = 0.026).Anxiety symptoms were significantly positively correlated with global score of PSQI (p = 0.004) and its subscale (subjective sleep quality, sleep latency, sleep disturbance, use of medications and daytime dysfunction) and insomnia (p = 0.001).ConclusionsAbnormal sleep quality and insomnia were detected in patients with psoriasis not using any immunosuppressive or systemic therapy, and this could be due to the psoriasis disease itself or due to the associated anxiety and depression associated with psoriasis. Screening for psychiatric symptoms specially that of depression, anxiety, and sleep among patients with psoriasis is of utmost importance for better quality of life. Thus, collaboration between dermatologists and psychiatrists may show better life quality for these cases and better treatment outcomes.

Assessing sleep health dimensions in frontline registered nurses during the COVID-19 pandemic: implications for psychological health and wellbeing.

The COVID-19 pandemic altered work environments of nurses, yielding high rates of stress and burnout. Potential protective factors, including effective sleep, may influence psychological health and wellbeing. Evidence about sleep in nurses may help develop interventions that mitigate burnout and poor psychological outcomes. A cross sectional survey was distributed across three hospitals to nurses in New York City (NYC). During the first wave of the pandemic (March-April 2020), NYC had the highest incidence of laboratory-confirmed COVID-19 cases (915/100 000) and half of all COVID-related deaths nationwide. Multivariable logistic regression was used to determine associations between Pittsburgh Sleep Quality Index (PSQI) global sleep score, PSQI sleep dimensions, and psychological health (burnout, depression, anxiety, and compassion fatigue), unadjusted and then controlling for individual and professional characteristics. More than half of the participants reported burnout (64%), depression, (67%), and anxiety (77%). Eighty percent of participants had PSQI global scores >5 (poor sleep) (mean 9.27, SD 4.14). Respondents reporting good sleep (PSQI ≤ 5) had over five times the odds of no burnout (OR: 5.65, 95% CI: 2.60, 12.27); increased odds of screening negative for depression (OR: 6.91, 95% CI: 3.24, 14.72), anxiety (OR: 10.75, 95% CI: 4.22, 27.42), and compassion fatigue (OR: 7.88, 95% CI: 1.97, 31.51). Poor subjective sleep quality PSQI subcomponent was associated with burnout (OR: 2.21, 95% CI: 1.41, 3.48) but sleep duration subcomponent was not (OR: 0.84, 95% CI: 0.59, 1.19). Daytime dysfunction was significantly associated with all psychological outcomes. Sleep disturbances and medications yielded higher anxiety odds. Overall, sleep quality appears more strongly related to burnout than sleep duration in nurses working during the COVID-19 pandemic. Sleep interventions should target individual sleep dimensions in nurses.

Age-Based Differences in Sleep Quality, Pre-Sleep Arousal, and Psychosocial Factors during the Second Wave Lockdown of the COVID-19 Pandemic in Georgia—A Higher Vulnerability of Younger People

The COVID-19 pandemic has deeply disrupted sleep and mental health of people around the world. We aimed to investigate age-based differences in the prevalence of and relationship between sleep quality, pre-sleep arousal, and psychosocial factors during the second wave lockdown of the COVID-19 pandemic in Georgia. Data were collected through an online survey (n = 1117). Participants were categorized into four age groups: 18-29, 30-41, 42-53, and 54-70 years. The youngest participants reported the most prevalent disruption of sleep behavior. Overall, 58.3% of respondents were poor sleepers. The Pittsburgh Sleep Quality Index (PSQI) global score was highest in the youngest age group but the difference was not significant. There was a significant difference in the PSQI component scores for subjective sleep quality, sleep latency, and daytime dysfunction, all being worse in young respondents. We also observed a significantly higher prevalence rate of worse sleep quality in the youngest age group, relative to the pre-pandemic period. On the other hand, the oldest respondents showed significantly greater use of sleeping medications. Significantly higher levels of somatic and cognitive pre-sleep arousal, perceived stress, feeling depressed, anxious, and socially isolated were reported by the youngest age group. Study findings indicate a higher vulnerability of younger people to the impact of the COVID-19 pandemic. Assessment of pre-sleep arousal and implementation of specific, age-based interventions may prove beneficial to improve possible consequences of the pandemic on sleep and mental health.

Health and wellness for disadvantaged older adults: The AFRESH pilot study.

Older adults are unaware of the biological mechanisms that contribute to the development of disabilities, chronic conditions, and frailty, yet, when made aware, desire to employ lifestyle changes to mitigate these conditions. We developed the AFRESH health and wellness program and report on pilot testing undertaken in a local older adults apartment community. After program development, pilot testing was conducted. Participants: Older adults (N = 20; age 62+) residing in an apartment community. Procedures: Collection of baseline objective and self-report measures with a focus on physical activity; administration of the 10-week AFRESH program via weekly sessions; collection of follow-up data 12 and 36 weeks after baseline data collection. Data analysis: Descriptive statistics, growth curve analyses. Significant increases were observed for grip strength (lbs) (T1:56.2; T2:65.0 [d = 0.77]; T3:69.4 [d = 0.62], p = .001), the 6-min walk test (meters) (T1:327m: T2:388.7 m [d = 0.99]; T3:363.3 m [d = 0.60], p = .001), the Rapid Assessment of Physical Activity (RAPA) strength and flexibility score, and the Pittsburg Sleep Quality Index (PSQI) global score. These effects showed some attenuation by the final time point. By combining novel educational content (bioenergetics), facilitation of physical activity, and habit formation, AFRESH is a multicomponent intervention that shows promise for future research.
