Background/Objectives: This study examined the effects of an intervention on anthropometrics, body composition, physical fitness, and sleep quality in aged individuals, comparing a control group (N = 11) and an experimental group (N = 13) across two measurement points. Methods: A multicomponent training program of 8 months was adopted as the intervention group. A bioimpedance balance, functional fitness test, and Pittsburgh Sleep Quality Index measured body composition, functional fitness, and sleep quality. Results: Both groups showed minimal changes in body mass and hand grip strength. However, the experimental group experienced significant improvements in physical fitness, including a 26% increase in arm curl repetitions, an 18% reduction in 5 times sit-to-stand (5TSTS) completion time, and a 29% rise in 2-min step test (2MST) steps, indicating enhanced muscle endurance and cardiovascular fitness. Flexibility decreased significantly in the experimental group, while body fat percentage was reduced by 10%. Sleep quality improved by 47% in the experimental group but declined by 14% in the control group. Correlational analysis revealed that better sleep quality was linked to improved fitness performance and reduced body fat in the experimental group, with post-intervention results further confirming the connection between sleep and fat reduction. In the control group, improved sleep quality was associated with higher metabolic rates after 8 months. Conclusions: These findings suggest that the intervention positively impacted physical fitness and sleep quality, with potential benefits for overall health. [ABSTRACT FROM AUTHOR]

Background: The COVID-19 pandemic has profoundly affected young adults' lives globally, including those in Germany. This study investigated mental health and quality of life during the pandemic, with a particular focus on mood. Immune fitness, the body's capacity to respond to health challenges (such as infections) by activating an appropriate immune response, was assessed as a physical health indicator. Methods: Data were collected from 317 participants, aged 18 to 35, via an online survey conducted between November 2021 and March 2022. Participants included 103 men (32.5%) and 214 women (67.5%), with a mean age of 25.5 years (SD = 4.1). Results: Compared to pre-pandemic levels, significant declines in mood, quality of life, immune fitness, and sleep quality were observed during the lockdown periods of the COVID-19 pandemic (p < 0.0125). The most pronounced effects were observed during the second lockdown, with declines extending into the second no-lockdown period for fatigue, depression, happiness, optimism, and immune fitness (p < 0.0125). Significant sex differences were found for the magnitude of mood effects (anxiety, depression, stress). No significant differences were found according to age or occupational status (student vs. work). Conclusions: The COVID-19 pandemic and associated lockdown periods had a significant negative effect on the mood, immune fitness, and well-being of young adults living in Germany.

This study aimed to investigate the effects of high-intensity running on the autonomic nervous system and sleep quality of male long-distance runners and to examine the impact of wearing magnetic garments on these parameters. Fifteen highly trained male collegiate long-distance runners participated in a randomized, double-blind crossover study. Participants completed two 30 km runs (30k-RUN) during a 10-day training camp. After each run, they wore either magnetic (MAG) or non-magnetic control (CTRL) garments. Sleep quality and heart rate variability (HRV) were assessed using a wrist-worn device before and after each 30k-RUN. Wearing MAG garments post-30k-RUN resulted in significantly longer deep sleep duration compared to CTRL. HRV analysis revealed that the MAG condition led to a significantly higher root mean square of successive RR interval differences and high-frequency power, indicating enhanced parasympathetic activity. The low-frequency to high-frequency ratio was significantly lower in MAG than in CTRL. Perceived recovery scores were significantly higher in MAG than in CTRL. The findings of this study suggest that wearing magnetic garments following high-intensity endurance running may promote parasympathetic dominance and improve sleep quality in male long-distance runners. These findings indicate that magnetic garments may be a practical method for enhancing recovery in athletes following intense training. [ABSTRACT FROM AUTHOR]

Mattress comfort, often associated with firmness, is a complex construct influenced by factors such as material composition, construction, and personal preference. In this short communication paper, we indirectly investigated the effects of long-term mattress use on its hardness and sleep quality by observing the changes in the mattress. A mechanical durability test was performed on two structurally different mattress samples (with polyurethane core and pocket spring core) using a modified method based on the EN 1957 standard, aiming to understand the long-term effects of mattress characteristics on sleep quality. Preliminary results confirm that the mattress samples can maintain firmness and support during long-term use. The polyurethane foam mattress experienced initial compression but quickly stabilized, while the pocket spring mattress showed slight softening, maintaining overall firmness. For the polyurethane mattress, after the initial drop, the hardness value stabilized, varying between 7.53 and 9.03 N/mm, and at the end of the test, it stopped at 8.60 N/mm. The firmness rating stabilized at 4.3, showing minimal fluctuation between 4.0 and 4.6 throughout the process, while the total height loss was 3.79 mm. The hardness value of pocket spring mattresses generally decreased with increasing test cycles (it started at 5.86 N/mm and ended at 5.21 N/mm). The firmness remained relatively stable, varying between 7.3 and 7.1, and the total height loss was only 2.86 mm. The findings suggest that the firmness of a mattress can be changed with its use, highlighting the need for further research on a larger number of samples in the direction of the long-term implications of these changes on sleep comfort.

Background: Primary dysmenorrhea is a leading cause of chronic cyclic pelvic pain, contributing to a reduced quality of life and sleep disturbances in women. The objective of this study was to assess the effectiveness of transcutaneous tibial nerve stimulation (TTNS) in improving the quality of life, sleep, and overall health perceptions of participants compared to a control group of women with dysmenorrhea over short-term, medium-term, and long-term periods. Methods: A single-blind, controlled clinical trial was conducted, with participants randomly assigned to an experimental group (receiving TTNS) or a control group (receiving sham TTNS). Both groups underwent 12, weekly 30 min sessions using the NeuroTrac™ PelviTone electrostimulation device. Outcomes related to quality of life, sleep deficiency, and overall improvement were evaluated at three time points: short-term (post-treatment), medium-term (1–3 months), and long-term (6 months). Results: Of the 61 participants initially randomized (31 in the experimental group and 30 in the control group), 55 completed the study and were included in the final analysis. A statistically significant improvement was observed in the experimental group in both physical and mental health components, as measured by the SF-36v2® questionnaire, following 12 weeks of intervention, compared to the control group, persisting 6 months after the intervention. Additionally, statistically significant differences in overall improvement were noted between the two groups, as measured by the PGIC questionnaire at the end of treatment (p = 0.0103) and 6 months post-treatment (p = 0.0432). Conclusions: TTNS appears to be a safe and effective strategy for enhancing quality of life and overall health in women with PD, potentially reducing the reliance on pharmacological treatments or more invasive methods.

Background: The aim of this study was to investigate the effects of pulmonary rehabilitation (PR) and additional progressive muscle relaxation (PMR) techniques in patients with long-term COVID-19 symptoms. Methods: We included 61 patients with long COVID-19 symptoms and randomly assigned them to two groups: PR only (group 1 with 30 subjects) and PR with PMR (group 2 with 31 subjects). The PR program consisted of gradual aerobic conditioning, strength training, and breathing exercises. Group 2 received additional 20 min daily sessions of progressive muscle relaxation techniques. Results: Following a 21-day intervention, it was observed that both groups had noteworthy improvements in lung function, exercise capacity, and sleep quality with statistical significance (p < 0.0001). Group 2 showed significant improvements in overall health (as measured by the General Health Questionnaire-12), patient health (as assessed by the Patient Health Questionnaire-9), general anxiety levels (as indicated by the Generalized Anxiety Disorders Scale-7), and sleep quality (as measured by the Pittsburgh Sleep Quality Index), with statistical significance (p < 0.0001), compared to group 1. Moreover, the statistical analysis demonstrated no significant difference in exercise capacity improvement between group 1 and group 2, as indicated by a p-value of 0.1711. Conclusions: The addition of progressive muscle relaxation to pulmonary rehabilitation significantly enhances mental health outcomes, particularly in reducing anxiety and improving sleep quality, for patients with long-term COVID-19 symptoms. These findings suggest that incorporating PMR into PR programs offers a valuable non-pharmacological approach to improving overall patient well-being during long-term COVID-19 recovery.

Background/Objectives: A well-established association exists between the development of hypertension and sleep quality. The connection between self-reported sleep quality and the onset of hypertension is particularly significant in populations with metabolic deterioration, such as in Mexico. Methods: The Tlalpan 2020 Cohort was analyzed to explore this association. Clinical and anthropometric characteristics, along with the Medical Outcomes Study Sleep Scale (MOS-SS), were compared between participants who developed hypertension and those who did not over a follow-up period of 30.8 months. The potential role of poor sleep quality in the development of hypertension was assessed. Results: Among 1520 participants, 12% developed hypertension. These individuals had higher anthropometric and laboratory values and reported poorer sleep quality. An elevated sleep problems index was associated with a 50% higher relative risk of developing hypertension (OR: 1.5; 95% CI: 1.087 to 2.069). Additionally, self-reported snoring was associated with hypertension onset (36.3 vs. 43.3; p = 0.019). Conclusions: Poor sleep quality and respiratory disturbances during sleep increase the risk of developing hypertension. Furthermore, hypertension was associated with snoring, highlighting the importance of early interventions to improve sleep quality. [ABSTRACT FROM AUTHOR]

Objective: The aim of this secondary analysis was to compare the effects of time-restricted eating (TRE) versus daily calorie restriction (CR) on sleep quality, duration, insomnia severity, and risk of obstructive sleep apnea in adults with obesity over one year. Methods: A total of 90 participants were randomized to one of three groups for 12 months: 8 h TRE (eating only between 12 p.m. and 8 p.m.); CR (25% daily calorie restriction) or a no-intervention control group. Results: By the end of the study, weight loss was 4.61 kg (95% CI; 7.37 to 1.85 kg; p ≤ 0.01) for the TRE group and 5.42 kg (CI; 9.13 to 1.71 kg; p ≤ 0.01) for the CR group, with no statistically significant difference between TRE and CR (0.81 kg [CI; 3.07 to 4.69]; p = 0.68]). Self-reported sleep quality, sleep duration, insomnia severity, and risk of obstructive sleep apnea did not change in the TRE or CR groups versus controls by month 12. Conclusions: These findings suggest that the weight loss produced by TRE and CR does not have any impact on various sleep parameters in adults with obesity over one year. [ABSTRACT FROM AUTHOR]

Background: Frailty has become a common health issue among older adults, imposing a burden on both society and individuals. The relationship between social participation and frailty has received widespread attention, but the mechanism remains to be explored. The aim of this study is to explore the impact of social participation on frailty among older adults and to analyze the mediating role of loneliness and sleep quality, providing suggestions to alleviate frailty. Methods: Data related to social participation, loneliness, sleep quality, and frailty from 7779 older adults were collected from the Chinese Longitudinal Healthy Longevity Survey (CLHLS 2018). The chain mediation model was conducted to explore the relationship between variables, and the Bootstrap method was used to examine the path coefficients. Results: Social participation negatively affected frailty (β = −0.00391049, 95% CI = [−0.042296, −0.035465]); the indirect effect of social participation on frailty mediated by loneliness was −0.0019505 (95% CI = [−0.002551, −0.001371]); the indirect effect of social participation on frailty mediated by sleep quality was −0.0011104 (95%CI = [−0.001692, −0.000557]); the effect mediated by both loneliness and sleep quality was −0.0004263 (95% CI = [−0.000593, −0.000304]). Conclusions: Social participation negatively affected frailty. Loneliness and sleep quality not only mediated independently, but also played a chain mediating role. This suggested that encouraging older adults to engage in more social participation, reducing loneliness, and improving sleep quality are feasible measures to improve frailty. [ABSTRACT FROM AUTHOR]

While research on autism spectrum disorder (ASD) has been growing, not enough research has been conducted to understand the impact of autistic traits and the broader autism phenotype (BAP), especially on the sleep quality and well-being of university students. The focus of this paper is to review the existing research on this topic and identify the key areas of interest for future research, presented in the form of a narrative review. While the review identifies the need for research on the topic, it also identifies other factors such as gender, age, culture, and internet and smartphone use that may have an impact on the relationship between autistic traits, sleep quality and well-being in university students. The review also identified the importance of using a larger sample size, appropriate measures, especially for quantifying autistic traits, and an appropriate analysis strategy involving a multivariate analysis.

Background/Objectives: Chronic fatigue syndrome (CFS) and post-COVID syndrome (PCS) pose a substantial socioeconomic burden. The aim of this systematic review was to assess current evidence regarding the effect of the most popular forms of movement-based mindful exercises, i.e., qigong, tai chi, and yoga, on fatigue and associated symptoms in CFS and PCS. Methods: CINAHL, Embase, PsycINFO, PubMed, Scopus, and the Cochrane Library were searched from inception to October 2023. Randomized controlled trials (RCTs) where qigong, tai chi, or yoga were compared with waitlist, no intervention, or active controls were included. Independent reviewers participated in data extraction, and evaluated risk of bias, spin of information, completeness of intervention description, and certainty of the evidence (GRADE). Meta-analyses were conducted. The primary outcome was the level of fatigue. Secondary measures were the severity of anxiety and depressive symptoms and sleep quality. Results were expressed as mean difference (MD) or standardized mean difference (SMD) with a 95% confidence interval (CI). Results: Thirteen RCTs with 661 participants were included, with most studies presenting a moderate or high risk of bias. Mindful exercises were more effective than control interventions to alleviate fatigue: SMD (95%CI) = −0.44 (−0.63 to −0.25), I2 = 48%, p < 0.0001. Positive effects were also observed for secondary outcomes. The certainty of the evidence was low or very low. Conclusions: Qigong, tai chi, and yoga may be effective to reduce fatigue and improve anxiety, depression, and sleep quality in adults with CFS or PCS. However, serious methodological concerns limit the clinical applicability of these findings. [ABSTRACT FROM AUTHOR]

Higher lighting intensity promotes workers' productivity but few studies focus on the problems caused by lower lighting intensities at tunnel construction sites without natural light. The purpose of this study is to explore the relationship between light intensity and workers' sleep quality, alertness, vitality, and work productivity through a theoretical structural equation model based on the literature review. Data were collected through a questionnaire survey, and 5792 valid responses were adopted for the analysis. First, the results showed that greater lighting intensity promoted workers' productivity directly and indirectly through three mediators: sleep quality, alertness, and vitality. Then, the whole sample was classified into four groups: high intensity/high comfort, moderate intensity/moderate comfort, moderate intensity/low comfort, and low intensity/low comfort. The clustered results showed that the lighting conditions of tunnel construction sites were generally poor and that lighting comfort promoted workers' productivity to some extent. Besides, the influence of lighting intensity on productivity declined with improved lighting conditions while the impact of lighting intensity on workers' physiological and psychological status showed differing trends as lighting conditions varied. However, the relationships between workers' physiological and psychological status and productivity remained stable regardless of the lighting conditions. The findings could provide a reference for developing corresponding measures to promote workers' productivity. [ABSTRACT FROM AUTHOR]

Background: There is considerable evidence supporting the elevated risk of mental health problems in individuals with evening chronotype relative to those with morning or intermediate chronotypes. Recent data, however, suggest that this risk may be explained, at least partially, by poor sleep quality. Methods: This study aimed to further clarify the roles of chronotype and sleep quality in mental health outcomes (depression, anxiety, stress) in young individuals (18–40 years) living in the UK (n = 185) or Germany (n = 209). Results: Consistent with our recent observations in a comparable North Indian sample, we found that poor quality of sleep had significantly positive associations with adverse mental health outcomes both in the UK and Germany-based samples. Significant associations between evening chronotype and poor mental health were also evident, but these associations were fully mediated by poor quality of sleep in both samples. Conclusions: These observations suggest that efforts to identify sleep disruption in a timely manner and promotion of good sleep may prevent mental health problems, especially in individuals with evening chronotype and other known risks for mental disorders.

Stress is widely known to have debilitating effects on physical health and mental wellbeing, particularly on one's coping styles, personality traits, and outlook on life. Cumulative and chronic stress, which can serve as a triggering or aggravating factor for many pathological disorders if left unaddressed, has been linked to many life-threatening diseases. While many studies have looked at how optimism and pessimism are used as a form of coping mechanism, few have examined how different bio-psycho-social reactions to stress shape the level of optimism and pessimism. Using a sample of adult individuals aged 18 and older in the United States (n = 3361), this study addressed the following research questions: (1) What types of stress are predictive of optimism and pessimism? (2) Which responses to stress and coping mechanisms are most predictive of optimism and pessimism? (3) Do optimism and pessimism share the same stress-related risk and protective factors? Overall, this study found that while optimism and pessimism share conceptual similarities, they are not necessarily influenced by the same stress mechanisms. Stress, whether personal or financial, was associated with a negative outlook on life. This study showed that having good sleep quality and a lower number of psychological stress symptoms was linked to increasing optimism and reducing pessimism, while overeating or eating unhealthily was connected to both optimism and pessimism. Additionally, this study found that exercise/walking and emotional support mediated the effects of the responses to stress on the respondents' level of optimism and pessimism. [ABSTRACT FROM AUTHOR]

This study aimed to evaluate the effectiveness of virtual reality (VR) in the mental state and quality of sleep improvement and physical activity (PA) increase of patients diagnosed with breast cancer (BC). A total of 33 subjects divided into experimental (EG, n = 17) and control (CG, n = 16) groups were assessed with the Mental Adjustment to Cancer Scale (Mini-MAC), International Physical Activity Questionnaire (IPAQ), Pittsburgh Sleep Quality Index (PSQI), and the Modified Hospital Anxiety and Depression Scale (HADS-M) at four time points. The experimental intervention consisted of eight VR TierOne sessions. Significant differences favoring the EG were identified in the group x time interactions for the main outcomes: destructive style of coping with the disease (p < 0.001), walking (p = 0.04), moderate (p < 0.001) and overall activity (p = 0.004), quality of sleep (p < 0.001), depressive symptoms (p < 0.001), anxiety levels (p < 0.001), aggression levels (p = 0.002), and overall HADS (p < 0.001). Trends, favoring the EG, in the constructive style of coping, sedentary behavior and intensive PA, and sleep efficiency and sleeping time were also found. A VR intervention improves general well-being in terms of the measured parameters. [ABSTRACT FROM AUTHOR]

Sleep position recognition plays a crucial role in enhancing individual sleep quality and addressing sleep-related disorders. However, the conventional non-invasive technology for recognizing sleep positions tends to be limited in its widespread application due to high production and computing costs. To address this issue, an enhanced stacking model is proposed based on a specific air bag mattress. Firstly, the hyperparameters of the candidate base model are optimized using the Bayesian optimization algorithm. Subsequently, the entropy weight method is employed to select extreme gradient boosting (XGBoost), support vector machine (SVM), and deep neural decision tree (DNDT) as the first layer of the enhanced stacking model, with logistic regression serving as the meta-learner in the second layer. Comparative analysis with existing machine learning techniques demonstrates that the proposed enhanced stacking model achieves higher classification accuracy and applicability.

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease associated with sleep disturbance, namely insomnia and sleep-disordered breathing. This study aims to evaluate the overall sleep characteristics of ALS patients, their association with lung function tests, and possible predictive survival factors. We conducted a retrospective observation study among ALS patients monitored during a pulmonology consultation. Type one polysomnography (PSG) and lung function tests were performed once the patients presented with sleep-related symptoms, and the relationship between their parameters was assessed, as well as a survival analysis. We included 35 patients, with an overall diminished sleep efficiency, a partially conserved forced vital capacity (FVC), and low maximal inspiratory pressure (MIP). A positive correlation between FVC and REM sleep percentage was observed. A survival analysis showed that a normal rapid eye movement (REM) sleep percentage and respiratory disturbance index (RDI) ≥ 15/h were independent predictors of survival. We observed a trend for higher sleep quality in patients with conserved lung function. A better sleep quality was associated with a higher survival. Obstructive events (reduced or absence of airflow associated with continued or increased inspiratory effort) did not seem to impact survival. [ABSTRACT FROM AUTHOR]

The aim of this study is to investigate body posture, physical exercises, head–neck relationship, and sleep quality among university students. A total of 96 students, with an average age of 20.86 ± 1.24 years and an average BMI of 23.41 ± 2.56, voluntarily participated in the study. The REEDCO Posture Evaluation (RPE) was used to assess the participants' body posture scores. Head and neck measurements were taken using the Apecs-AI Posture Evaluation and Correction System® (Apecs Posture Analysis Pro Plus Version 8.2.6). Sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI). Pearson correlation analysis indicated that increased caffeine consumption was associated with poorer sleep quality (r = 0.267, p < 0.05). Additionally, increased participation in physical activities was associated with improved sleep quality, with those engaging in sports having better sleep quality scores (r = −0.278, p < 0.05). As physical activity increased, REEDCO scores decreased (r = −0.423, p < 0.05), while scores for right head (r = 0.210, p < 0.05) and left head (r = 0.247, p < 0.05) increased. Significant negative correlations were found between REEDCO scores and right head (r = −0.296, p < 0.05) and left head (r = −0.463, p < 0.05) scores. In conclusion, due to the limited number of studies investigating head–neck relationships and sleep quality, definitive conclusions cannot be drawn; further and more comprehensive research is needed.

Chronotypes play a crucial role in regulating sleep–wake cycles and overall health. The aim of this study was to investigate chronotype, sleep quality, polymorphisms of clock genes and the level of leptin in serum. We used standardized questionnaires to assess chronotype and sleep quality. Genetic analysis was performed to determine the selected clock gene polymorphism. Serum leptin level was measured by the Elisa method. The results showed that serum leptin concentration was elevated in women, as well as in men who had a high waist-to-hip ratio (WHR) and body mass index (BMI). The evidence indicated that younger students (<22 years old) were most likely to experience poor sleep quality. Nevertheless, our multivariate analysis revealed that young age and a morning-oriented chronotype were associated with better sleep quality. We noted that clock gene polymorphisms were present in 28.6% of the participants. Moreover, polymorphisms of PER1 c.2247C>T (rs2735611) and PER2 c.-12C>G (rs2304672) genes were associated with serum leptin level and chronotype, respectively. These findings provide insights into the relationships between chronotype, sleep quality, clock gene polymorphisms and obesity risk in biomedical students. Understanding these factors can contribute to better sleep management and potential interventions to improve health outcomes in humans. [ABSTRACT FROM AUTHOR]

Good, satisfying, sleep is a key indicator and determinant of health and wellness. However, there is no consensus about how to define and measure good sleep. The present research aimed to define sleep satisfaction through the extant literature and disentangle it from sleep quality, a conceptually similar construct. Systematic review methods were adapted for a rapid review approach. The entire review was completed in eight weeks. Tabulation coding with content analysis was used to identify key categories and synthesize findings. A systematic process for generating construct definitions was followed. Database search yielded 51 eligible studies (N > 218,788), representing diverse adult populations, in 20 countries. Designs varied in rigour. Sleep satisfaction was defined as a personal, introspective, and global judgment about one's feelings of contentment with one's sleep, at a particular point in time. Sleep satisfaction was understood as an indicator of general health, impacted by and varied as a function of one's sleep environment and individual-level characteristics. This rapid review contributes to the literature by providing the first systematically generated definition of sleep satisfaction, with strong implications for measurement, research, and practice.

The college years represent a crucial developmental period in which unhealthy behaviors, including smoking, alcohol consumption, inadequate physical activity (PA), poor sleep quality, and unhealthy nutrition habits are often acquired, influencing the onset or exacerbation of pre-existing mental disturbances such as anxiety, depression, or difficulties in emotion regulation. Our aim was to analyze the effect of the intensity of physical activity (PA) on the emotional, behavioral, and cognitive variables in a sample of young people. We recruited 103 participants (19.85 ± 0.25) who completed several online questionnaires (IPAQ-SF, STAI-t, DERS, UPPS-P, ISP-20, and Mini-IPIP). Subsequently, face-to-face sessions were conducted to assess the cognitive variables and to collect more details about their lifestyle habits, including drug use, sleep quality, and leisure activities. Based on the IPAQ-SF results, we categorized the sample into three groups: light PA (n = 47), moderate PA (n = 29), and vigorous PA (n = 27). Vigorous PA group showed better emotional regulation, lower impulsivity, fewer prefrontal symptoms and unhealthy behaviors, better sleep quality, and more leisure activities. No significant cognitive differences were found. It seems that young people are a vulnerable group with emotional and impulsivity traits and engaging in intense PA appears to be a promising avenue for managing these symptoms. In conclusion, our study suggests that young people are a vulnerable group with emotional and impulsivity traits that may precipitate in future mental disorders. Nevertheless, engaging in PA, particularly at high intensity, appears to be a promising avenue for reducing and managing these symptoms during this critical period of life. [ABSTRACT FROM AUTHOR]

During the COVID-19 lockdown, a high prevalence of disruption in lifestyle habits was reported, especially concerning sleep habits. The present study aimed to explore the relationship between lifestyles and the COVID-19 lockdown on subjects living in Mexico. A cross-sectional survey was conducted. An online questionnaire was administered to survey participants. A clustering procedure was performed to identify groups of survey respondents with similar characteristics. There were 155 survey respondents. Most of them were women (83%) of young age. The clustering identified two distinct groups of subjects, i.e., Cluster 1 and 2. The subjects in Cluster 2 were younger, more likely to use social media, and spent much more time watching TV/surfing the internet than subjects in Cluster 1. Furthermore, the prevalence of problems with falling and staying asleep during the lockdown was higher in Cluster 2 than in Cluster 1 (14% in Cluster 2 vs. 4% in Cluster 1) even though nobody from Cluster 2 had sleep problems before the lockdown. The study showed that younger respondents were those more affected by lockdown measures. [ABSTRACT FROM AUTHOR]

Background: Limited information is available on factors that affect the burden tinnitus. The aim of this study is to investigate the association between tinnitus burden and demographic, patient-specific and tinnitus characteristics. Secondly, it was examined which variables could predict a change in tinnitus burden after 12 months. Method: In a prospective Dutch cohort of 383 tinnitus patients seeking medical help, tinnitus complaints, demographics, tinnitus characteristics, psychological wellbeing and quality of life were assessed using an online self-report survey at three timepoints (start, 6 months, 12 months). The main outcome variables for tinnitus burden are the Tinnitus Questionnaire (TQ) and Visual Analog Scale (VAS) for tinnitus burden and loudness. Results: Several variables (time, sex, education level, life events, anxiety and depression, sleep issues, tinnitus loudness, hearing impairment and treatment) were significantly associated with tinnitus burden. Additionally, tinnitus burden after 12 months was associated with anxiety, following treatment, sleep issues, negative life events and hearing impairment (increase) and anxiety, total of life events and environmental quality of life (decrease) predicted the tinnitus burden after 12 months. Conclusions: Several factors, such as education level, life events, psychological factors and sleep quality, are related to tinnitus burden and can predict tinnitus burden over time.

Glycine, the simple amino acid, is a key component of muscle metabolism with proven cytoprotective effects and hypothetical benefits as a therapeutic nutrient. Cell, in vitro, and animal studies suggest that glycine enhances protection against muscle wasting by activating anabolic pathways and inhibiting proteolytic gene expression. Some evidence indicates that glycine supplementation may enhance peak power output, reduce lactic acid accumulation during high-intensity exercise, and improve sleep quality and recovery. This literature review critically explores glycine's potential as an ergogenic aid and its relevance to muscle regeneration, muscle strength, endurance exercise performance, and sleep quality. It also underscores key areas for future research. It is concluded that more randomized controlled clinical trials in humans are needed to confirm glycine's potential as a dietary supplement to support muscle function, recovery, and overall athletic performance as an ergogenic aid and to establish nutritional recommendations for athletic performance. Also, it is essential to consider that high doses (>500 mg/kg of body mass) could induce cytotoxic effects and contribute to acute glutamate toxicity. [ABSTRACT FROM AUTHOR]

Background: Advanced glycation end products (AGEs), a group of food processing byproducts, have been implicated in the development of various diseases. However, the relationship between circulating AGEs and sleep disorders remains uncertain. Methods: This cross-sectional study elucidated the association of plasma AGEs with sleep disorders among 1732 Chinese adults who participated in the initial visit (2019–2020) of the Tongji–Shenzhen Cohort (TJSZC). Sleep behavior was assessed using self-reported questionnaires and precise accelerometers. Plasma levels of AGEs, including Nε-(Carboxymethyl)lysine (CML), Nε-(Carboxyethyl)lysine (CEL), and Nδ-(5-hydro-5-methyl-4-imidazolone-2-yl)-ornithine (MG-H1), were quantified by ultra-high performance liquid chromatography–tandem mass spectrometry (UPLC-MS/MS). Results: In logistic regression, per IQR increment in individual AGEs was associated with an increased odds ratio of short sleep duration (CML: 1.11 [1.00, 1.23]; CEL: 1.16, [1.04, 1.30]), poor sleep quality (CML: 1.33 [1.10, 1.60]; CEL: 1.53, [1.17, 2.00]; MG-H1: 1.61 [1.25, 2.07]), excessive daytime sleepiness (CML: 1.33 [1.11, 1.60]; MG-H1: 1.39 [1.09, 1.77]), and insomnia (CML: 1.29 [1.05, 1.59]). Furthermore, in weighted quantile sum regression and Bayesian kernel machine regression analyses, elevated overall exposure levels of plasma AGEs were associated with an increased risk of sleep disorders, including short sleep duration, poor sleep quality, excessive daytime sleepiness, and insomnia, with CML being identified as the leading contributor. Insufficient vegetable intake and higher dietary fat intake was associated with an increase in plasma CEL. Conclusions: These findings support a significant association between plasma AGEs and sleep disorders, indicating that AGEs may adversely influence sleep health and reducing the intake of AGEs may facilitate preventing and ameliorating sleep disorders.

Excessive daytime sleepiness (EDS) and insomnia (IN) complaints represent the most common sleep/wake disorders. Currently, the specific needs of these patients and their relatives, as well as the overall socio-economic burden of IN and EDS remains widely unexplored. This pilot study to be carried out in Switzerland is a retro- and prospective, national, one-center cohort observational study for the systematic evaluation of the burden of EDS and IN and its evolution 12 months after the first assessment. Patient recruitment will be organized through 7–8 primary care providers (primary/general care practitioners and pharmacies). Primary outcomes are the prevalence of EDS/IN in the primary care setting and the association between EDS/IN with health-related quality of life (QOL) as assessed with the established instruments. Secondary outcomes are the association between EDS/IN with the presence of comorbidities, number of injuries/accidents, and number of sick/leave days for the subgroup of working subjects. Calculation of direct per-patient costs will be undertaken to analyze the economic implications of sleep/wake disorders, providing valuable insights into the financial burden experienced by affected individuals within the healthcare system. This research will provide information on the feasibility of such a study and inform on aspects of the QOL most associated with EDS/IN. Based on this pilot project, a European multicenter study on the burden of sleep/wake disorders will be conducted by the European Academy of Neurology. [ABSTRACT FROM AUTHOR]

Background: Physiotherapy plays a key role in managing fibromyalgia, a multifaceted disorder, through a combination of active and passive treatments. The purpose of this review is to compare the efficacy of "hands-off" treatments alone versus the combination of "hands-off" and "hands-on" therapies. Methods: MEDLINE (PubMed), CENTRAL, and Embase were searched. English-language randomized controlled trials involving adults with fibromyalgia were included. The included studies were divided into subgroups to reduce the possible heterogeneity. We calculated the standardized mean difference or mean difference with 95% confidence intervals for the continuous data according to the outcome measures. We used the risk ratio for dichotomous data of the drop-out rate of the studies. Results: We included and analyzed seven RCTs. The meta-analysis showed no significant results in the outcomes, pain, QoL, health status, and drop-out rate. We found significant results (p < 0.001) in favor of combining "hands-off" and "hands-on" treatments for the rest quality (SMD 0.72, 95% CI 0.35 to 1.09). Conclusions: This review increases the treatment options available for clinicians. Up to now, the main guidelines on managing fibromyalgia suggest only approaches based on "hands-off" treatments. These findings suggest that other approaches based on mixed interventions combining "hands-off" and "hands-on" treatments did not reduce the patient outcomes. Moreover, the mixed intervention led to better results for the patients' sleep quality than the "hands-off" treatments alone. [ABSTRACT FROM AUTHOR]

Background/Objectives: Fibromyalgia (FM) is a chronic syndrome characterized by widespread musculoskeletal pain, fatigue, sleep disturbances, and mental health issues. It affects approximately 1.78% of the general population; an estimated 4:1 ratio between women and men is observed. It significantly impacts quality of life and carries both clinical and social stigma. This study aims to evaluate the relationship between drug use and mental health in female patients with fibromyalgia. Methods: This study is prospective, observational, and cross-sectional. A questionnaire was administered to 544 subjects, achieving a representative sample size from a population of 800,000 subjects by using an algorithm for proportion estimation with a known sampling frame. The selection was non-random, making the sampling non-probabilistic. Logistic regression models were applied to assess the effect of drug use on perception of mental health; presence of symptoms such as comprehension and memory problems, insomnia, depression, and anxiety; and severity of cognitive symptoms and non-restorative sleep. To quantify the impact, odds ratios and confidence intervals have been observed. Results: The findings indicate the non-recommended use of medications and reveal the ineffectiveness and adverse effects of drug interactions on mental health. The use of benzodiazepines and sedative-hypnotics is significantly associated with a negative perception of mental health. Benzodiazepines do not improve symptoms or significantly reduce their severity. SSRI antidepressants do not enhance mental health perception; however, when used exclusively, they are effective in reducing the severity, but not the prevalence, of cognitive symptoms. Conclusions: The results highlight the complexity of pharmacological management in FM and raise concerns about the inappropriate use of ineffective or counterproductive drug interactions affecting patients' mental health. They underscore the need for multidisciplinary and personalized strategies that include close and careful monitoring, as well as the simultaneous use of non-pharmacological treatments that have demonstrated evidence in improving quality of life without negatively affecting mental health, such as patient education, psychological therapy, physiotherapy, and mindfulness.

Background/Objectives. A notable decline in physical activity from late adolescence to early adulthood affects young women especially. This study aimed to investigate adherence to an unsupervised virtual-guided high-intensity interval training (HIIT) exercise program among young women in Spain. Methods. A total of 106 participants were recruited and randomized to the Women's Involvement in Steady Exercise (WISE) trial exercise program, administered remotely via a mobile app, and a control group. The primary outcome was adherence measured through daily steps. Secondary variables were patient-reported outcomes of physical activity, quality of sleep, and quality of life, assessed with the International Physical Activity Questionnaire (IPAQ), the Pittsburgh Sleep Quality Index (PSQI), and the Health Lifestyle and Personal Control Questionnaire (HLPCQ), respectively. The assessments were performed over 6 months, before the intervention (T0), at the halfway of the program (T1), and at the end (T2). Results. Daily steps revealed a decrease from baseline to final assessment in both groups. Secondary outcomes indicated a shift in physical activity levels, showing a transition from low to moderate and high activity perception. While sleep quality deteriorated post-intervention, quality of life showed no changes. Conclusions. The WISE trial highlights the potential and challenges of an unsupervised virtual-guided HIIT program for young women. While an improvement in physical activity levels was noticed, it also led to a decrease in daily steps and poorer sleep quality. These findings suggest a complex relationship between exercise and lifestyle factors, which could potentially have the greatest impact. [ABSTRACT FROM AUTHOR]

Introduction: Members of consecrated life communities exhibit homogeneity with regard to factors that are relevant to health, including diet, daily activities, religiosity, and housing. This may be indicative of the manner in which the community influences the formation of the health-seeking attitudes of its members. Purpose of the study: The objective of this study was to validate a survey about health awareness and health-seeking attitudes among consecrated people and to identify potential issues to be improved. In addition, the study aspires to provide insights into the lifestyles of consecrated persons in Poland, based on the results of the survey and available data. Materials and Methods: The study group included 27 female participants, members of societies of apostolic life and non-habitual apostolic religious congregations of the Roman Catholic Church. The participants were invited to express their comments and suggestions on the survey, with the purpose of validating the survey before using it as a tool for a larger study. Results: All participants agreed that nutrition, rest, and physical activity had a significant impact on health. A total of 89% of participants considered their lifestyle as healthy and a similar proportion indicated that living in a consecrated community had a positive impact on their health, with the most positive influence of factors related to spiritual exercise, rhythm of the day, and sense of interpersonal connection within the community. Approximately 44% of participants indicated that their attitude was based on a healthy diet and adequate sleep quality. However, they identified an existing need to improve the balance between work and rest. Additionally, 4% of respondents admitted irregular eating habits, ignoring quality of alimentary products, non-satisfactory rest time, and insufficient sleep. Conclusions: Even though the purpose of this study was only to validate a survey predestined for a larger study, it already gives an insight into the level of awareness of health behavior and lifestyle of residents of religious communities.

The COVID-19 pandemic has left behind mental health issues like anxiety, depression, and sleep disorders among survivors. This study assessed the efficacy of spa therapy in enhancing psychological well-being and sleep quality in individuals with chronic arthro-rheumatic, respiratory, and otorhinolaryngological diseases, including COVID-19 recoverees. Our prospective observational study included 144 Caucasian subjects from three Italian spas who underwent a 2-week spa therapy cycle, involving balneotherapy and/or inhalation treatments. Symptoms were assessed with the Visual Analogue Scale (VAS), psychological well-being with Depression Anxiety Stress Scales-21 items (DASS-21), and sleep quality with the Insomnia Severity Index (ISI). Significant reductions in VAS scores for arthro-rheumatic, respiratory, and otorhinolaryngological symptoms were observed after spa therapy, as well as for DASS-21 and ISI scores for sleep quality, transitioning to less severe insomnia categories. Females had more pronounced improvements in DASS-21 scores and sleep quality. Subjects with and without prior SARS-CoV-2 infection experienced significant reductions in anxiety, depression, and stress, with more pronounced improvements in those without prior infection. COVID-19 survivors also showed significant ISI score improvements. Spa therapy is a promising complementary treatment for improving mental health and sleep quality in chronic disease patients, including COVID-19 survivors. [ABSTRACT FROM AUTHOR]

Background and Objectives: Volleyball demands high levels of anaerobic strength, flexibility, agility, and mental focus. Adequate sleep has been shown to enhance athletic performance and cognitive function. This study investigates the impact of post-lunch naps of varying durations (25 and 45 min) on the physiological performance and cognitive focus of elite volleyball players. Materials and Methods: Sixteen elite volleyball players (8 male, 8 female) with at least 7 years of competitive experience participated in a randomized crossover study. They underwent three experimental conditions: no nap (No-Nap), a 25-min nap (N25), and a 45-min nap (N45). Physical performance was measured through counter-movement jumps (CMJ) and volleyball agility tests, while cognitive function was assessed using the D2 attention test. Statistical analysis included repeated measures ANOVA to examine the differences between nap conditions and gender-specific responses. Results: Significant improvements in both physical performance and cognitive focus were observed in the N25 and N45 conditions compared to the No-Nap condition (indicating the effectiveness of short naps in enhancing both physical and mental performance). Males outperformed females in most physical metrics, while females scored higher on the D2 attention test (suggesting possible gender-specific responses to napping). The 25-min nap showed slightly better results in terms of sleep quality and subsequent performance (confirming that shorter naps may be more beneficial). Conclusions: Post-lunch naps, especially of 25 or 45 min, enhance both physiological and cognitive performance in elite volleyball players. These findings suggest that integrating short naps into athletes' training regimens can improve performance and focus, with potential gender-specific benefits. Further research is needed to explore long-term effects and variations across other sports. [ABSTRACT FROM AUTHOR]

Background and Objectives: Sex differences are unclear in geriatric sleep medicine, and most evidence comes from inference from preclinical bases or clinical studies conducted on younger people. The aim of this study is to explore sex differences in sleep quality and daytime sleepiness in a cohort of elderly people. Materials and Methods: This cross-sectional study involved subjects aged 65 years or older undergoing multidimensional evaluation, including sleep quality and daytime sleepiness assessment with validated tools. Results: This study included 226 subjects (69.5% women), the majority of whom showed poor sleep quality (64.2%). A logistic regression model put one before the other sleep quality and gender. It initially showed that men were about half likely as women to have poor sleep quality (OR 0.48, 95%CI 0.27–0.86). Nonetheless, after adjusting for cognitive status and mood, the difference became smaller and insignificant (OR 0.72, 95%CI 0.38–1.38). Conclusions: Sex differences in elderly people's sleep quality seem to not be independent, appearing to be affected by alterations in cognitive status and mood. [ABSTRACT FROM AUTHOR]

Background and Objectives: This study aims to examine the factors affecting the daily functioning of patients with obstructive sleep apnea (OSA). Materials and Methods: In addition to the polysomnography records of 361 patients, participants completed the Turkish FOSQ-10 (Functional Outcomes of Sleep-10), Medical Outcome Survey Short Form-12, Epworth Sleepiness Scale (ESS), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI). First, the psychometrics properties of the Turkish FOSQ-10 were evaluated. Then, factors affecting daily functioning were examined through univariate and multivariate analyses. Results: Of all participants, 68.7% (n = 248) were male, and the average age was 47.94 ± 11.08. According to the OSA category, 23% (n = 83) were mild, 22.7% (n = 82) were moderate, 45.2% (n = 163) were severe, and 9.1% (n = 33) were OSA negative. The Turkish FOSQ-10 was found to be a valid and reliable scale through validity and reliability analyses. The moderate and severe OSA patients had different FOSQ-10 Total scores compared to the negative OSA group. Daily functioning was positively associated with overall quality of life while inversely associated with depression, being anxious, and daytime sleepiness in OSA patients. In a multiple regression model, BDI, mental component summary-12, physical component summary-12, and ESS scores were significantly related to the FOSQ-10 Total score in OSA patients (p < 0.05). Conclusions: The daily functioning of moderate and severe OSA patients was worse than that of the negative OSA group. Depression, quality of life, and daytime sleepiness were simultaneously important variables associated with daily functioning in OSA patients. [ABSTRACT FROM AUTHOR]

Objectives: Evidence shows that obstructive sleep apnea (OSA) is associated with the development of stroke. This study investigates the relationship between OSA and post-stroke complications, addressing the limited data on how OSA influences the severity and development of these complications through a systematic review of existing literature. Methods: Data was collected from PubMed, Web of Science, and Scopus databases up to December 2023. Studies meeting the inclusion criteria were selected, and statistical analyses were performed using Review Manager 5.4.1. A random-effects model was used for pooling data with heterogeneity, and findings were presented using standard ratios with 95% confidence intervals. Results: The analysis included nine studies. Stroke patients with OSA did not show a significantly higher risk of post-stroke complications, which include mild cognitive impairment, dementia, insomnia, fatigue, reduced sleep quality, depression, anxiety, recurrent strokes, and death, compared with those without OSA (RR = 1.05, 95% CI 0.97 to 1.13). However, patients with high stroke severity and OSA had a slightly higher risk of post-stroke complications (RR = 1.06, 95% CI 1.01 to 1.12). Conclusions: This systematic review and meta-analysis suggests that OSA confers a higher risk of post-stroke complications in patients with high stroke severity. Further studies are required to explore the impact of OSA on post-stroke complications. [ABSTRACT FROM AUTHOR]

Background/Objectives: Population aging poses many challenges to public health, highlighting loneliness and social isolation as severe problems that affect the physical and mental health of older adults. During the COVID-19 pandemic, these became aggravated. The objective of the present study was to assess the prevalence of loneliness and its relationship with social isolation, depression, cognitive deterioration, sleep quality, and the level of physical mobility and functioning of older adults in Health Area 3 of the Region of Murcia. Methods: A descriptive, observational, and cross-sectional study was performed. The inclusion criteria were age ≥ 65, living in Health Area 3 of the Region of Murcia, and not being institutionalized. The following variables were evaluated: sociodemographic variables, loneliness (UCLA scale), social isolation (DUFSS), depression (GDS), cognitive deterioration (Pfeiffer), sleep quality (PSQI), and mobility (Barthel index). A univariate and multivariate regression model was created to examine how the dependent variable was related to the independent variables. Results: A total of 102 older adults participated in the study. Of these, 31.4% perceived unwanted loneliness and 14.7% low social support. The multivariate regression analysis showed that social isolation, geriatric depression, and cognitive deterioration were significant predictors of loneliness. Conclusions: The findings highlight the importance of developing multifaceted interventions that address not only social isolation but also other interrelated factors such as depression, cognitive deterioration, and sleep quality. The strategies should be centered on community programs and support networks. It is fundamental to perform longitudinal studies to better understand the causal relationships between these variables.

Objectives: Eating disorders (EDs) have emerged as a growing public health concern. However, the role of sleep in this context remains underexplored. The aim of this cross-sectional study was to determine the associations between sleep parameters and chronotype with ED risk in a sample of university students in Spain. Methods: ED risk was assessed via the Sick, Control, One stone, Fat, Food Questionnaire, and sleep quality was assessed via the Pittsburgh Sleep Quality Index. Other sleep parameters and chronotypes were self-reported. Sociodemographic, body composition, lifestyle, and depressive symptom data were collected. Logistic and linear regression models adjusted for the main confounders were used to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) of the study associations. Results: A total of 403 students (70.2% female) aged 18 to 30 years participated in the study. Those reporting poor sleep quality (OR = 1.85, 95% CI 1.08–3.17, p = 0.025) and ≤6 h of night-time sleep duration (OR = 4.14, 95% CI 2.00–8.57, p < 0.01) were more likely to be at risk of EDs in the adjusted analyses. The association between night-time sleep duration and the risk of ED did not remain significant when we adjusted for sleep quality. In addition, an evening chronotype was associated with an increased risk of EDs (OR = 1.68, 95% CI 1.07–2.66, p = 0.039) only before adjustment for confounders. Conclusions: Among university students, poorer sleep quality was cross-sectionally associated with EDs. Future prospective studies are needed to examine whether promoting sleep quality may serve as an effective strategy for preventing the risk of EDs. [ABSTRACT FROM AUTHOR]

Background: Sleep disorders have been poorly described in congenital (CDM) and childhood (ChDM) myotonic dystrophy despite being highly burdensome. The aims of this study were to explore sleep disorders in a cohort of Italian CDM and ChDM and to assess their association with motor and respiratory function and disease-specific cognitive and behavioral assessments. Methods: This was an observational multicenter study. Reported sleep quality was assessed using the Pediatric Daytime Sleepiness Scale (PDSS) and Pediatric Sleep Questionnaire (PSQ). Sleep quality was correlated to motor function (6 min walk test, 6MWT and grip strength; pulmonary function (predicted Forced Vital Capacity%, FVC% pred.); executive function assessed by BRIEF-2; autism traits assessed by Autism Spectrum Screening Questionnaire (ASSQ) and Repetitive Behavior Scale-revised (RBS-R); Quality of life (PedsQL) and disease burden (Congenital Childhood Myotonic Dystrophy Health Index, CCMDHI). Results: Forty-six patients were included, 33 CDM and 13 ChDM, at a median age of 10.4 and 15.1 years. Daytime sleepiness and disrupted sleep were reported by 30% children, in both subgroups of CDM and ChDM. Daytime sleepiness correlated with autism traits in CDM (p < 0.05). Disrupted sleep correlated with poorer executive function (p = 0.04) and higher disease burden (p = 0.03). Conclusions: Sleep issues are a feature of both CDM and ChDM. They correlate with behavioral issues and impact on disease burden. [ABSTRACT FROM AUTHOR]

Atopic dermatitis (AD) is a chronic inflammatory skin disease with a complex pathophysiology characterized by intense pruritus, often associated with psychological stress and atopic and non-atopic comorbidities that significantly reduce quality of life. The psychological aspects of AD and the interaction between the mind and body via the skin–brain axis have led to an interest in mind–body therapies (MBT). The aim of this article is, therefore, to reinforce the importance of psychodermatological care in AD. We performed a focused literature review on holistic practices or integrative MBT in AD, including education, cognitive behavioral therapy, habit reversal, meditation, mindfulness, hypnotherapy, eye movement desensitization and reprocessing, biofeedback, progressive muscle relaxation, autonomous sensory meridian response, music therapy, massage, and touch therapy. A multidisciplinary holistic approach with MBT, in addition to conventional pharmacologic antipruritic therapies, to break the itch–scratch cycle may improve AD outcomes and psychological well-being. Although there is a paucity of rigorously designed trials, evidence shows the potential benefits of an integrative approach on pruritus, pain, psychological stress, anxiety, depressive symptoms, and sleep quality. Relaxation and various behavioral interventions, such as habit reversal therapy for replacing harmful scratching with massaging with emollient 'plus', may reduce the urge to scratch, while education may improve adherence to conventional therapies.

Introduction: Accurately detecting arousal events during sleep is essential for evaluating sleep quality and diagnosing sleep disorders, such as sleep apnea/hypopnea syndrome. While the American Academy of Sleep Medicine guidelines associate arousal events with electroencephalogram (EEG) signal variations, EEGs are often not recorded during home sleep testing (HST) using wearable devices or smartphone applications. Objectives: The primary objective of this study was to explore the potential of alternatively relying on combinations of easily measurable physiological signals during HST for arousal detection where EEGs are not recorded. Methods: We conducted a data-driven retrospective study following an incremental device-agnostic analysis approach, where we simulated a limited-channel setting using polysomnography data and used deep learning to automate the detection task. During the analysis, we tested multiple signal combinations to evaluate their potential effectiveness. We trained and evaluated the model on the Multi-Ethnic Study of Atherosclerosis dataset. Results: The results demonstrated that combining multiple signals significantly improved performance compared with single-input signal models. Notably, combining thoracic effort, heart rate, and a wake/sleep indicator signal achieved competitive performance compared with the state-of-the-art DeepCAD model using electrocardiogram as input with an average precision of 61.59% and an average recall of 56.46% across the test records. Conclusions: This study demonstrated the potential of combining easy-to-record HST signals to characterize the autonomic markers of arousal better. It provides valuable insights to HST device designers on signals that improve EEG-free arousal detection. [ABSTRACT FROM AUTHOR]

Grounding, a therapeutic technique involving direct contact with the earth, has been proposed by various studies to potentially have beneficial effects on pressure, sleep quality, stress, inflammation, and mood. However, the scientific evidence supporting its sedative effects remains incomplete. This study examined the sedative effectiveness of an earthing mat on sleep quality and investigated the underlying neural mechanisms using electroencephalography (EEG) analysis in rodents, focusing on orexin and superoxide dismutase (SOD) levels in the brain. Rats were randomly assigned to four groups: the naïve normal group (Nor), the group exposed to an earthing mat for 7 days (A-7D), the group exposed to an earthing mat for 21 days (A-21D), and the group exposed to an electronic blanket for 21 days (EM). EEG results revealed that the A-21D group exhibited significantly reduced wake time and increased rapid eye movement (REM), non-rapid eye movement (NREM), and total sleep time compared to the Nor group (p < 0.05). Moreover, the A-21D group demonstrated a significant increase in NREM sleep (p < 0.001), REM sleep (p < 0.01), and total sleep time (p < 0.001), along with a decrease in wake time compared to the EM group (p < 0.001). The orexin level in the A-21D group was significantly lower compared to the Nor group (p < 0.01), while SOD1 expression was markedly elevated in the A-21D group compared to the Nor group (p < 0.001). These results suggest that the earthing mat may represent a promising new method for promoting sleep quality and could serve as an effective therapeutic technique. [ABSTRACT FROM AUTHOR]

The university population is at a vital stage of human development for acquiring an active lifestyle. Following this lifestyle will bring benefits in adulthood. This study seeks to analyse the relationship between physical activity and bodily pain, mental hyperactivity, and sleep quality as a function of the intensity of physical activity. A comparative, descriptive, and exploratory study is presented in a sample of 506 university students. The International Physical Activity Questionnaire, the Chronic Pain Grade Questionnaire, the Mental Hyperactivity Questionnaire, and the Pittsburgh Sleep Quality Index were used. The proposed model analyses the relationships of physical activity to bodily pain, mental hyperactivity, sleep disturbances, and time to fall asleep. The fit of the different adjustment indices is satisfactory (X2 = 0.47, df = 1, pl = 0.48, IFI = 0.99, CFI = 0.97; NFI = 0.91; RMSEA = 0.01). The relational analysis shows a positive relationship of physical activity to bodily pain (r = 0.02; p < 0.01), mental hyperactivity (r = 0.054; p < 0.01), sleep disturbances (r = 0.029; p < 0.01), and time to fall asleep (r = 0.047; p < 0.01). Multi-group structural equation analysis indicates that there are differences in the causal relationships of physical activity to sleep quality, mental hyperactivity, and bodily pain as a function of exercise intensity. The conclusion is that the intensity at which physical activity is performed plays a key role in mental and physical health. [ABSTRACT FROM AUTHOR]

Background: The ASCAPE project aims to improve the health-related quality of life of cancer patients using artificial intelligence (AI)-driven solutions. The current study employs a comprehensive dataset to evaluate sleep and urinary incontinence, thus enabling the development of personalized interventions. Methods: This study focuses on prostate cancer patients eligible for curative treatment with surgery. Forty-two participants were enrolled following their diagnosis and were followed up at baseline and 3, 6, 9, and 12 months after surgical treatment. The data collection process involved a combination of standardized questionnaires and wearable devices, providing a holistic view of patients' QoL and health outcomes. The dataset is systematically organized and stored in a centralized database, with advanced statistical and AI techniques being employed to reveal correlations, patterns, and predictive markers that can ultimately lead to implementing personalized intervention strategies, ultimately enhancing patient QoL outcomes. Results: The correlation analysis between sleep quality and urinary symptoms post-surgery revealed a moderate positive correlation between baseline insomnia and baseline urinary symptoms (r = 0.407, p = 0.011), a positive correlation between baseline insomnia and urinary symptoms at 3 months (r = 0.321, p = 0.049), and significant correlations between insomnia at 12 months and urinary symptoms at 3 months (r = 0.396, p = 0.014) and at 6 months (r = 0.384, p = 0.017). Furthermore, modeling the relationship between baseline insomnia and baseline urinary symptoms showed that baseline insomnia is significantly associated with baseline urinary symptoms (coef = 0.222, p = 0.036). Conclusions: The investigation of sleep quality and urinary incontinence via data analysis through the ASCAPE project suggests that better sleep quality could improve urinary disorders.

Background: To evaluate analgesic practices in perioperative treatment during the SARS-CoV-2 pandemic; recording parameters collected in the PAIN OUT database, and to compare COVID and no-COVID data. Methods: Data were analyzed for 277 patients (87 COVID-19 confirmed diagnosis and 190 non-COVID): years aged, gender, minutes of surgery duration, Likert Scale punctuation, hours in severe pain, minimum and maximum pain intensity, interference with sleep quality, anxiety, need for help, nausea, drowsiness, itching, dizziness, perception of care, pain relief, participation, satisfaction, and information received. Results: Postoperative mortality 1 month after surgery was recorded at 25.3% in COVID-19. Significant differences were found in postoperative pain intensity (p = 0.019), time with severe pain (p < 0.01), lower sleep quality (p < 0.01), and better outcomes in functional items (p < 0.01); there were more side effects and satisfaction with pain relief (p < 0.01) in COVID-patients than with no COVID-19 patients. Conclusions: In conclusion, COVID-19 patients presented greater intensity and duration of severe postoperative pain, greater somnolence, pruritus, and dizziness, lower physical activity limitation, and higher quality index.

Acromegaly is a rare endocrine syndrome characterized by unrestrained growth hormone (GH) secretion from a GH-secreting pituitary neuroendocrine tumor (PitNET). Data on sleep disorders are scanty and mainly linked to Obstructive Sleep Apnea Syndrome (OSAS). This study aimed to evaluate the prevalence of insomnia and sleep quality in a cohort of patients with a low risk of OSAS before and after therapies for acromegaly. A total of 27 naïve acromegalic patients (mean age 55.15 ± 10.53 years) were submitted to a psychometric sleep evaluation and compared to a matched control group of 24 Non-Functioning Pituitary micro-Adenoma patients (mean age 51.08 ± 11.02 years). A psychometric sleep evaluation was carried out 4 years later, after achieving acromegaly control in all patients. The role of different therapies for acromegaly (somatostatin analogues, pegvisomant, or adenomectomy) was evaluated. At the initial evaluation, most untreated acromegalic patients had a higher rate of impaired sleep quality and clinical insomnia than NFPA patients (p = 0.001 ES = 1.381, p = 0.001 ES = 1.654, respectively). Patients treated with somatostatin analogues or pituitary adenomectomy had an improvement in insomnia parameters (p = 0.046 ES = 0.777, p = 0.038 ES = 0.913, respectively). Conversely, in patients treated with pegvisomant, sleep quality and insomnia worsened (p = 0.028 ES = 1.002, p = 0.009 ES = 1.398, respectively). In summary, therapies for acromegaly seem to have divergent effects on perceived sleep disorders. Concerning sleep, somatostatin analogues and adenomectomy seem to have favorable effects on the psychometric parameters of sleep. [ABSTRACT FROM AUTHOR]

Obstructive sleep apnea (OSA) often goes unrecognized despite common symptoms, such as excessive daytime sleepiness, fatigue, and impaired quality of life (QoL). Continuous positive airway pressure (CPAP) is the gold standard treatment for OSA, but optimal daily usage and time needed for observable effects remain unclear. This study aimed to investigate the short-term effects of CPAP on daytime sleepiness and QoL in patients with severe OSA. Medical records were collected from 87 patients with severe OSA who initiated CPAP therapy. Also, validated questionnaires were used before and after one month of CPAP to analyze QoL—the Calgary Sleep Apnea Quality of Life Index (SAQLI), the Cues to CPAP Use Questionnaire (CCUQ), and daytime sleepiness—the Epworth Sleepiness Scale (ESS). Multiple regression analysis was conducted to identify predictors of CPAP usage. Of the total participants aged 55.6 ± 12.5, 77% were males, and 62% were CPAP adherent. Reductions in daytime sleepiness (ESS) were noted, as well as improvements in both overall QoL (SAQLI) and specifically in the domains of daily functioning, social interactions, emotional well-being, and symptom perception. Important cues for CPAP usage recognized by patients were physicians' instructions and physicians' concern regarding their patients' condition. Furthermore, multiple regression revealed higher SAQLI scores and lower ESS scores as positive predictors of CPAP usage, along with lower AHI after one month of CPAP being associated with sufficient adherence.

Sleep disorders increase with age and are known risk factors for several mental and physical diseases. They also significantly contribute to a lower quality of life. Nonpharmaceutical approaches, such as cognitive behavioral therapy for insomnia, sleep hygiene advice, relaxation exercises, and physical activity programs, can be delivered directly to patients via mHealth technologies, thereby increasing the accessibility of such interventions and reducing health care-related costs. This scoping review aims to evaluate the effectiveness of mHealth interventions for improving sleep quality among older adults. Published studies in the last 10 years (2013–2023) were identified by searching electronic medical databases (PubMed, PsycINFO, CINAHL, and Scopus) in July 2023 and were independently reviewed by two different authors. The analysis of the data was performed in 2023. The research retrieved 693 records; after duplicates were removed, 524 articles were screened based on their title and abstract, and 28 of them were assessed in full text. A total of 23 studies were excluded because they did not meet the inclusion criteria in terms of population age (60 years or over) or type of intervention (mHealth-based) or because they addressed secondary insomnia. A total of five studies were included in this review, and all of them reported improvements in subjective sleep quality after the application of the mHealth interventions. Two studies also conducted objective assessments of sleep outcomes using actigraphy, reporting improvements only in some of the variables considered. Despite the limited number of available studies, these results are promising and encourage further research. [ABSTRACT FROM AUTHOR]

The application of far-infrared blankets has shown certain benefits in health promotion and therapy, such as improving blood circulation and alleviating muscle pain. However, the effects of such blankets on increasing deep sleep, reducing blood pressure, enhancing memory, dilating microvessels for blood flow, reducing chronic inflammation, and decreasing fatigue remain to be studied. We aim to investigate the effects of the DAZZEON αSleep® far-infrared blanket on these indicators. This study adopted a double-blind design, recruiting 24 male participants aged over 45 years, divided into two groups of 12 each: (A) a placebo group and (B) a DAZZEON αSleep® group. The participants used the blanket every night for two weeks, with sleep records taken using a wearable device and blood pressure, blood oxygen levels, arterial stiffness, and surface temperature measured before and after the intervention. Blood samples were collected for an analysis of inflammation and sleep-related blood indicators (serotonin and melatonin), and exercise tests were conducted to assess fatigue improvement. Compared with before the intervention, the blanket significantly increased changes in grip strength and reaction time. Additionally, it significantly increased blood serotonin, melatonin, and nitric oxide concentrations (p < 0.05), thus significantly increasing deep sleep and REM sleep durations (p < 0.05) and improving subjective sleep quality (p < 0.05). This study confirmed that using the DAZZEON αSleep® far-infrared blanket for 14 consecutive days helps to improve blood circulation, reduce vascular age and arterial stiffness, increase serotonin and melatonin levels, and improve sleep quality, as well as enhances muscle strength and reaction time.

Sleep quality significantly impacts individuals' overall health, especially in older adults. Older adults often face comorbid conditions, polypharmacy (the intake of five or more medications per day), and medication non-adherence, which are common among those with sleep disorders. The purpose of this systematic review is to examine the relationship between sleep quality and medication adherence in older adults and to describe the measuring instruments used. A systematic review was performed following the PRISMA guidelines. The PubMed, Scopus, Cochrane Library, and CINAHL databases were screened from January 2024 to March 2024. Nine articles were included in the final synthesis based on the inclusion and exclusion criteria. The review found that poor sleep quality is significantly associated with reduced medication adherence in older adults. The key sleep determinants linked to medication non-adherence include sleep disorders, sleep efficiency, sleep duration, and daytime dysfunctions. Inappropriate medication prescriptions have been associated with reduced sleep efficiency. The tools for assessing sleep quality and medication adherence are predominantly subjective and varied. To address these challenges, a comprehensive geriatric assessment should include investigations into sleep disorders and comorbidity factors. Additionally, nursing educational interventions could be pivotal in improving medication adherence among older adults. [ABSTRACT FROM AUTHOR]

A randomized, double-blind and controlled study was conducted to assess the effectiveness of the intake of 250 mL of lactose-free skimmed milk enriched with ashwagandha (Withania somnifera) alone or combined with tryptophan vs. non-enriched milk (control) on the subjective quality of sleep in healthy adults with sleep problems. The duration of supplementation was 90 days. Fifty-two eligible subjects were assigned to the study arms of ashwagandha 250 mg, ashwagandha 250 mg plus tryptophan 175 mg, ashwagandha 600 mg, and control with 13 subjects in each group. It was hypothesized that ashwagandha plus tryptophan could be superior to ashwagandha alone for improving sleep-related variables. Changes in the visual analogue scale (VAS) for sleep quality were significantly higher in the three experimental groups as compared with controls (p = 0.014). Improvements in the subscales of the Pittsburg Sleep Quality Index (PSQI) were found in all groups, but between-group differences were not significant. In the index of insomnia severity, decreases were higher in the three experimental groups as compared with controls especially in the group of ashwagandha 600 mg. Daytime somnolence was also reduced in the three experimental groups. Changes in anxiety levels and Morningness–Eveningness Questionnaire were not observed. The study products did not elicit changes in body composition and were well tolerated and safe. The data did not support the hypothesis, as the combination of ashwagandha and tryptophan did not show greater benefits in improving sleep quality than ashwagandha alone. However, the results from the three experimental groups containing ashwagandha were more favorable compared to the placebo group. [ABSTRACT FROM AUTHOR]
