The aim of the present study was to investigate the effects of multicomponent training on adropin, endothelial function, insulin resistance, and sleep quality in overweight older adults. In this randomized controlled study, 40 overweight older adults were randomly divided into training and control groups. The multicomponent training program including aerobic, resistance, and balance exercise was followed for 8 weeks, 3 days a week. Study variables were measured 48 hr before and after the intervention. After 8 weeks of multicomponent training, adropin (p =.01), nitric oxide (p =.01), and maximal oxygen uptake (VO2max; p =.002) increased, and glucose (p =.001), insulin (p =.001), insulin resistance (p =.01), systolic blood pressure (p =.01), and sleep disorders (p =.01) decreased significantly. Also, Pearson's test results showed a significant inverse relationship between adropin level (p =.01 and r = −.55) and glucose (p =.01 and r = −.51) with sleep disorders. It seems that multicomponent training increases adropin and improves insulin resistance, endothelial function, and sleep quality in older adults. [ABSTRACT FROM AUTHOR]

Purpose: To determine whether menstrual-cycle symptoms are associated with sleep in elite female athletes. Methods: Sleep was assessed for a minimum of 25 nights (range = 25–31) using activity monitoring and sleep diaries. Menstrual-cycle symptoms were collected over the same duration in 12 elite female professional soccer players. Generalized estimating equations were used to examine the relationship between the day of the menstrual cycle (from day 1) and total menstrual-cycle symptoms on sleep characteristics. Results: There was a significant relationship between sleep duration and the day of the menstrual cycle (P =.042) and total symptoms reported that day (P <.001), with sleep duration increasing by 21 minutes for every symptom reported. There was a negative day × symptom interaction on sleep duration (P =.004), indicating that with increased symptoms, the day of the menstrual cycle had a smaller relationship with sleep duration. Sleep efficiency (P =.950), wake after sleep onset (P =.217), and subjective sleep quality (P =.080) were not related to the day of the menstrual cycle. The total symptoms reported had no relationship with sleep efficiency (P =.220), subjective sleep quality (P =.502), or sleep latency (P =.740) but did significantly relate to wake after sleep onset (P <.001), with a significant day × symptom interaction (P <.001). Conclusions: Sleep duration increased from day 1 of the menstrual cycle and was associated with the number of menstrual-cycle symptoms reported. All other sleep metrics remained unchanged; however, total symptoms reported were related to wake after sleep onset. Monitoring and managing menstrual-cycle symptoms should be encouraged due to a potential relationship with sleep characteristics. [ABSTRACT FROM AUTHOR]

Purpose: Short sleep duration and poor sleep quality are common in swimmers. Sleep-hygiene strategies demonstrated beneficial effects on several sleep parameters. The present study assessed the impact of a multisession sleep-hygiene training course on sleep in elite swimmers. Methods: Twenty-eight elite swimmers (17 [2] y) participated. The sleep-hygiene strategy consisted of 3 interventions. Sleep was measured by actigraphy for 7 days before the beginning of the intervention (baseline), after the first collective intervention (postintervention), after the second collective intervention (postintervention 2), and, finally, after the individual intervention (postintervention 3). The Epworth Sleepiness Scale (ESS) was completed concurrently. Swimmers were classified into 2 groups: nonsomnolent (baseline ESS score ≤ 10, n = 13) and somnolent (baseline ESS score ≥ 11, n = 15). Results: All swimmers had a total sleep time of <8 hours per night. Sixty percent of swimmers were moderately morning type. Later bedtime, less time in bed, and total sleep time were observed in the somnolent group compared with the nonsomnolent group at baseline. An interaction between training course and group factors was observed for bedtime, with a significant advance in bedtime between baseline, postintervention 2, and postintervention 3 for the somnolent group. Conclusions: The present study confirms the importance of implementing sleep-hygiene strategies, particularly in athletes with an ESS score ≥11. A conjunction of individual and collective measures (eg, earlier bedtime, napping, and delaying morning training session) could favor the total sleep time achieved. [ABSTRACT FROM AUTHOR]

Purpose: This study examined posttravel perceptual responses of national-team footballers (soccer) following different flight paths, arrival/departure times, and trip contexts. Methods: Details of 396 flights from national-team players (N = 68) were obtained and verified via an online flight database. Each player provided ratings of perceptual fatigue, sleep, soreness, stress, and jet lag for 2 days before and after each trip. The flight path (continents of departure and arrival), travel context (into vs out of national team), and arrival and departure times were obtained for each trip. Linear mixed models compared the pretravel with posttravel change in perceptual responses based on flight path, context, and schedule. Results: Perceived jet-lag ratings were more responsive to travel variables (R2 =.48) than other perceptual ratings (R2 <.26). Travel from Asia to Europe (P <.05) and Europe to Australia (P <.001) had significantly higher jet-lag ratings than all other paths. Fatigue scores were worst following Asia to Europe (P <.05) and Europe to Australia (P <.05) travel, while sleep scores were worst following Europe to Australia travel (P <.01). Perceptual responses were poorer following travel from national team to club compared with all other travel contexts (P <.05). Arrival during the daytime (11 AM to 5 PM) resulted in better perceptual responses than early-morning or late-night arrivals (P <.05). Conclusions: Perceived jet-lag ratings are more responsive to travel demands than perceptual wellness scales in national-team football athletes. Poorer perceptual responses may be expected when travel is longer in nature, ends later in the day, or involves travel out of the national team back to club. [ABSTRACT FROM AUTHOR]

Objective: The study aimed to evaluate Zolpidem and Benzodiazepines prescription and dispensing data in private pharmacies in Brazil from 2014 to 2021. Methods: This retrospective cohort study was carried out with retrospective open data from the Brazilian Federal Government from January 2014 to August 2021 containing medicines registered in the National Controlled Products Management System (SNGPC). Results: Between January 2014 and August 2021, a total of 32,441,392 sales of thirteen drugs from the z-drug and benzodiazepine classes used to treat sleep disorders were recorded in Brazil. Throughout the entire period, clonazepam emerged as the most popular drug, accounting for 29.8% of total sales. Alprazolam followed in second place with 20.6% of sales, while zolpidem came in third with 14.4%. The normal-release form of zolpidem was consistently the highest-selling variant during the evaluation period. However, the fast-acting-release form exhibited the most significant growth, indicated by a noticeable upward trend in sales since 2020. In contrast, the extended-release form of zolpidem remained stable over the years. Conclusion: The increased sales of zolpidem in Brazilian private pharmacies raise concerns about potential misuse and dependence on this drug mainly for the treatment of insomnia. The epidemic of sleeping pills arises in a scenario of expectancy of short-term amelioration of symptoms, with no correspondence in best clinical practice. Education and counseling for both healthcare professionals and the general population are essential to address this growing health concern and ensure the safe and appropriate use of medications for sleep disorders.

Background: Insomnia is a prevalent sleep disorder affecting cognitive functions critical to academic performance. University students, particularly in high-stress academic settings, are highly vulnerable. Despite its significant impact on students' health and education, there is limited research on the prevalence of insomnia among university students in Saudi Arabia. This systematic review and meta-analysis aim to assess the prevalence of insomnia among university students in Saudi Arabia, focusing on demographic variations and academic settings, to provide evidence for targeted interventions. Methods: A comprehensive literature search was conducted across databases including PubMed, Scopus, and Web of Science, with additional manual searches. Inclusion criteria were cross-sectional studies addressing insomnia prevalence among Saudi university students, using standard diagnostic criteria. A total of 11 studies met the inclusion criteria, comprising data from diverse faculties, including medical and non-medical disciplines. Quality assessment was conducted using the Newcastle-Ottawa Scale. Statistical analyses were performed using a random-effects model to account for heterogeneity. Results: Eleven studies, involving a total of 8297 university students, were included in the analysis. Insomnia prevalence varied widely, ranging from 19.3% to 98.7%, with a pooled prevalence of 43.3% (95% CI 28.9–58.2%). Subgroup analyses showed a prevalence of 38.6% among medical students and 38.7% among female students. The analysis revealed high heterogeneity (I2 = 99.17%), indicating significant variability in study designs, populations, and diagnostic methods. Conclusions: Insomnia is highly prevalent among university students in Saudi Arabia, with significant variations across demographics and academic contexts. The findings underscore the urgent need for targeted interventions, including stress management, improved sleep hygiene education, and support systems to mitigate the impact of insomnia on academic performance and overall health. Future research should explore the longitudinal impacts of insomnia and the efficacy of tailored interventions in this population. [ABSTRACT FROM AUTHOR]

Deep brain stimulation is a well-established treatment for improving motor symptoms in Parkinson's disease. However, persistent non-motor symptoms, such as excessive daytime sleepiness, remain a significant challenge and necessitate further investigation. In this study, we conducted repeated measurements of daytime sleepiness using a modified multiple sleep latency test in a healthy monkey (macaca fascicularis), which was later rendered parkinsonian through MPTP administration. Deep brain stimulation targeting the lateral hypothalamic area revealed frequency-dependent modulation of both sleepiness level and core body temperature. High-frequency stimulation (80 Hz) increased sleepiness in the healthy state, while low-frequency stimulation (20 Hz) promoted wakefulness in the parkinsonian state. These findings suggest a promising therapeutic approach for addressing sleep/wake disturbances, not only in Parkinson's disease but also in other severe sleep disorders. [ABSTRACT FROM AUTHOR]

ABSTRACT Aims Methods and Results Conclusions This study aimed to determine the relationship between sleep problems, shock pain, and shock anxiety in patients with implantable cardioverter defibrillator (ICD) and the affecting factors.The population of this descriptive cross‐sectional study consisted of all patients who underwent ICD implantation in university hospital (N = 200), and the sample consisted of patients who met the inclusion criteria of the study (n = 132). Data were obtained using a “General Information Form”, the “Florida Shock Anxiety Scale (FSAS)”, the “Epworth Sleepiness Scale (ESS)”, the “Pittsburgh Sleep Quality Index (PSQI)”, and the “Visual Pain Scale (VPS)”. The mean age of the patients was 66.13 years. The VPS was 6.40 ± 3.36; the mean FSAS score was 29.98 ± 8.46; the mean PSQI score was 8.02 ± 3.81; the mean ESS score was 7.59 ± 4.10. PSQI had a statistically significant correlation with the total FSAS score (p < 0.001) and a statistically insignificant correlation with ESS (p > 0.001). Age, sex, marital status, smoking status, cohabitants, previous ICD shocks, the status of lying on ICD, and fear of dislocation of ICD affected the total FSAS score; sex, employment status, history of heart attack, defined sleep disorder, awakening from sleep due to nightmares, and cessation of breathing during sleep affected the total PSQI score; history of previously defined sleep disorder, history of heart attack, use of medication for a sleep disorder, the pain felt when lying on ICD, and pain experienced during ICD shocks affected the total ESS score. The mean shock VPS scores differed between patients who received an ICD shock during sleep and those who were awakened by nightmares.It was found that the shock anxiety and shock pain scores of ICD patients were above average, that they had poor sleep quality, and that their sleepiness was at the level of “normal but increased daytime sleepiness”.

Background: This study was aimed at analyzing cognitive function and quantitative electroencephalogram (qEEG) in patients with isolated REM sleep behavior disorder (iRBD) based on the presence of depression and at evaluating the impact of depression on phenoconversion to neurodegenerative diseases. Methods: Individuals diagnosed with iRBD via polysomnography were included. Based on the presence of depression, patients were categorized into two groups. Neuropsychological tests and qEEG were conducted following the diagnosis of iRBD, and outcomes were compared between the two groups. Patients were regularly followed to monitor their phenoconversion status. Cox regression analysis was performed to assess the hazard ratio associated with depression. Results: Ninety iRBD patients (70% males) were included, with a median age of 66.3 years. Depression was identified in 26 (28.9%) of these patients. The depressed group showed significantly poorer performance only in color reading subtest of Stroop (p = 0.029) compared to the nondepressed group, showing reduced processing speed. In qEEG, relative gamma power (p = 0.034) and high gamma power (p = 0.020) in the parietal region were significantly higher in the depressed group than in the nondepressed group. Depression was associated with a hazard ratio of 3.32 for the risk of phenoconversion to neurodegenerative diseases in iRBD patients (p = 0.011). Conclusion: Depressive symptoms in iRBD patients should be closely monitored as they could aggravate cognitive dysfunction and increase the risk of phenoconversion to neurodegenerative diseases.

Background: Studies have emphasised the adverse effects of poor sleep on human health, however, the correlation between sleep abnormalities and hypothyroidism remains unclear. This study evaluated whether sleep abnormalities may be related to increased prevalence of hypothyroidism in general US adults. Methods: In total, 9016 adults who participated in the National Health and Nutrition Examination Survey from 2007 to 2012 were analysed. A standardised questionnaire was used to collect data regarding sleep duration, self-reported trouble sleeping and sleep disorders. Values were assigned to the three aforementioned sleep factors, resulting in an overall sleep score of 0–3. The sleep patterns were divided into healthy sleep pattern (overall sleep score = 3), intermediate sleep pattern (overall sleep score = 2) and poor sleep pattern (overall sleep score = 0 or 1) according to a former study. Hypothyroidism was defined as thyroid-stimulating hormone (TSH) levels > 5.6 mIU/mL or the need to take thyroid hormones. Multivariable logistic regression analysis was performed to assess the relationship between sleep abnormalities and hypothyroidism. Results: The overall prevalence of hypothyroidism was 8.0% among the 9016 participants. Self-reported trouble sleeping (odds ratio [OR] = 1.38, 95% CI: 1.14–1.68, p = 0.001) and sleep disorders (OR = 1.40, 95% CI: 1.06–1.86, p = 0.0196) were associated with increased prevalence of hypothyroidism. Neither short sleep duration (OR = 0.99, 95% CI: 0.82–1.19) nor long sleep duration (OR = 0.98, 95% CI: 0.61–1.58) was significantly associated with hypothyroidism. Moreover, poor sleep pattern was significantly associated with increased prevalence of hypothyroidism (OR = 1.30, 95% CI: 1.03–1.66, p = 0.0301). Conclusions: Both trouble sleeping and sleep disorders were associated with increased prevalence of hypothyroidism. [ABSTRACT FROM AUTHOR]

Introduction: Depressive symptoms are most common non-motor symptoms in Parkinson's disease (PD), which is often overlooked due to absence of rapid and objective diagnostic biomarkers. Electroencephalography (EEG)-based event-related potentials (ERPs) is commonly used to assess emotional processes. The aim of this study was to investigate changes in ERPs in PD patients exhibiting depressive symptoms and to provide a reliable biomarker for assisting in the diagnosis of PD with depressive symptoms. Methods: We conducted a case–control study involving 30 PD patients with (dPD group) or without depressive symptoms (nPD group) and 13 age matched healthy controls (HC). We recorded EEG of the patients during the emotional picture stimulation task and analyzed the difference in the early ERPs potentials (P1, N170, early posterior negativity) and their correlation with the severity of symptoms in PD patients. Results: Our results found that P1 amplitude in the occipital region of the dPD group in response to emotional faces was significantly higher than that of nPD and HC group, and it was positively correlated with severity of depressive symptoms in PD patients. Conclusion: Our study shows that facial expression-induced enhancement of P1 amplitude can be utilized as a rapid and objective indicator to screen for depressive symptoms in PD.

Background: Limitations of conventional treatment methods for sleep disorders have driven the use and development of complementary and alternative therapies such as acupuncture. However, despite the surge in related studies, there is still a lack of visual analysis and detailed elaboration regarding the current status, international collaborations, and research hotspots of acupuncture for sleep disorders. Methods: We conducted a bibliometric analysis of publications on acupuncture for sleep disorders using the Web of Science Core Collection database from 2004 to 2023. We utilized the R package "bibliometrix" to count publications and citations, VOSviewer to create an inter-institutional referencing network, and CiteSpace to identify references and keywords with the highest citation bursts. Additionally, we employed a bibliometric online analysis platform designed for analyzing national partnerships. Results: A total of 432 pertinent papers were retrieved, with China being the most prolific contributor, accounting for 61.6% of the publications, followed by the United States and South Korea. Despite China's high output, its average article citation rate and proportion of international collaborations were notably lower than those of the United States. Key research institutions such as the University of Hong Kong, Shanghai University of Traditional Chinese Medicine, Memorial Sloan Kettering Cancer Center, and Guangzhou University of Chinese Medicine have played significant roles in this field. Among authors, Ka-Fai Chung from the University of Hong Kong stood out as the most productive. In terms of journals, MEDICINE was the most active, while SLEEP was considered the most authoritative. The clinical effects of acupuncture for insomnia have garnered significant attention in recent years, with electroacupuncture emerging as the prevailing technique for addressing sleep disorders. Conclusion: This bibliometric study effectively outlines the basic framework of knowledge surrounding acupuncture for sleep disorders over the past two decades, covering publications, countries, institutions, authors, and sources. It highlights promising clinical effects and underlying mechanisms of acupuncture, particularly for secondary insomnia and specific sleep disorders like restless legs syndrome. Moving forward, the focus and challenge for future research lie in the development of standardized study protocols and harmonization of efficacy assessment metrics. [ABSTRACT FROM AUTHOR]

Objective: Sleep disorder is a common non-motor symptom (NMS) of Parkinson's disease. However, the global research focus on Parkinson's sleep-related disorders (PDSDs) and future trends remains unclear. Currently, there is no bibliometric analysis of PDSDs. We aim to fill this gap, determine the status of current research, and predict future research hotspots. Methods: We selected 1490 publications from the Web of Science Core Collection (WoSCC) database from 2008 to 2023. Based on CiteSpace and VOSviewer, the analysis was performed from the perspectives of the trend in the number of annual publications, countries, institutions, authors, journals, and co-citations. Results: A total of 1490 publications from 590 authors from 409 institutions in 77 countries are included. The United States, China, and the United Kingdom are the leading countries. University College London (UCL) is the most prolific institution. Harvard University is the key for cooperation among institutions. Chaudhuri Kallol Ray is a leader in this field. "Movement Disorders" is the most influential journal. "A systematic review of the literature on disorders of sleep and wakefulness in Parkinson's disease from 2005 to 2015" is the publication with the highest co-citation intensity. Conclusion: The total volume of publications on PDSDs is on the rise, entering a relatively high-yield stage in 2020. The COVID-19 pandemic and the emergence of new keywords may be the reasons behind this phenomenon. "quality of life" and "circadian rhythm" are the mainstream topics of PDSD research. Daytime sleepiness is the PDSD subtype that has received the most attention. Sleep quality, biomarkers, and neurodegeneration are likely to become future research hotspots. [ABSTRACT FROM AUTHOR]

Background/objective: Emotional dysregulation is bidirectionally associated with sleep disturbances, with potentially critical implications for emotional reactivity, in patients with borderline personality disorder (BPD). This study evaluated subjective and objective sleep quality, emotional regulation, and emotional reactivity in 20 patients with BPD compared to 20 non-clinical individuals. Methods: Subjective and objective sleep quality was assessed using the Pittsburgh Sleep Quality Index and a 3-day actigraphic measurement. Emotional regulation was evaluated using the Difficulties in Emotion Regulation Scale and the Berkeley Expressivity Questionnaire. Furthermore, each participant underwent an emotional reactivity task selected from the International Affective Picture System. Results: Compared to control subjects, individuals with BPD reported poor subjective sleep quality and objective sleep continuity disturbances, with more sleep fragmentation and decreased sleep efficiency. Moreover, BPD patients showed emotional dysregulation and altered subjective reactivity to emotional stimuli, particularly positively valenced stimuli. Conclusion: These results suggest the importance of further clarifying the specific direction of sleep-dependent emotional modulation in individuals with BPD, with significant clinical implications for patients with co-occurring sleep disturbances.

Background Objectives Methods Results Conclusions Patients with Parkinson's Disease (PD) frequently exhibit non‐motor symptoms, particularly sleep disturbances. Sleep disorders in PD patients are intricately linked to the pathogenesis and progression of PD itself, exacerbating neurodegenerative processes and worsening patient quality of life.This review underscores the significance of sleep disorders in PD, highlighting their prevalence, impact on disease progression, and the bidirectional relationship between sleep disruption and neurodegeneration. It aims to enhance clinician awareness for better diagnosis and management of sleep‐related comorbidities in PD.A comprehensive literature search was conducted in PubMed and Scopus using key terms such as “sleep disorders”, “Parkinson's disease”, “REM sleep behavior disorder”, “restless legs syndrome”, “insomnia”, “obstructive sleep apnea”, “excessive daytime sleepiness”, “circadian rhythm disorders”, “sleep and neurodegeneration”.Sleep disorders are prevalent in PD affecting up to 90% of patients. Conditions such as insomnia, REM sleep behavior disorder, restless legs syndrome, obstructive sleep apnea, excessive daytime sleepiness, and circadian rhythm disorders are commonly reported. These disorders are linked to multifactorial biological mechanisms and are associated with more severe disease phenotypes. Of note, several evidence shows that sleep abnormalities may contribute to neuroinflammation and neurodegeneration, further accelerating the disease course.Sleep disturbances are critical non‐motor symptoms in PD. Early diagnosis and tailored management of sleep disorders are essential for improving clinical outcomes and potentially offering neuroprotective benefits. [ABSTRACT FROM AUTHOR]

Introduction: Adolescents' health and well-being are seriously threatened by suicidal behaviors, which have become a severe social issue worldwide. Suicide is one of the leading causes of mortality for adolescents in low and middle-income countries, with approximately 67,000 teenagers committing suicide yearly. Although an association between sleep disturbances (SDs) and suicidal behaviors has been suggested, data are still scattered and inconclusive. Therefore, to further investigate this association, we conducted a meta-analysis to verify if there is a link between SDs and suicidal behaviors in adolescents without diagnosed psychiatric disorders. Methods: PubMed, CENTRAL, EMBASE, and PsycINFO were searched from inception to August 30th, 2024. We included studies reporting the estimation of suicidal behaviors in adolescents from 12 to 21 years of age, with SDs and healthy controls. The meta-analysis was based on odds ratio (OR, with a 95% confidence interval ([CI]), estimates through inverse variance models with random-effects. Results: The final selection consisted of 19 eligible studies from 9 countries, corresponding to 628,525 adolescents with SDs and 567,746 controls. We found that adolescents with SDs are more likely to attempt suicide (OR: 3.10; [95% CI: 2.43; 3.95]) and experience suicidal ideation (OR: 2.28; [95% CI 1.76; 2.94]) than controls. Conclusion: This meta-analysis suggests that SDs are an important risk factor for suicidal ideation and suicide attempts in healthy adolescents. The findings highlight the importance of early identification of SDs to prevent suicidal behaviors in this population. Systematic review registration: PROSPERO, identifier CRD42023415526.

Background: The mental health of patients with chronic liver disease (CLD) warrants greater attention and understanding, especially concerning its risk factors. Method: Patients from our hospital's hepatology clinic were consecutively enrolled and completed a questionnaire assessing anxiety, depression, and sleep quality using the GAD-7, PHQ-9, and PSQI scales, respectively. Reliability and validity were evaluated with Cronbach's α and Kaiser-Meyer-Olkin (KMO). Continuous and categorical variables were analyzed using the Mann-Whitney U and Chi-square tests. Univariate and multivariate logistic regression were used to identify risk factors, while restricted cubic spline (RCS) were used to explored non-linear associations. Subgroup analyses were stratified by sex, age, and education. Result: A total of 1030 questionnaires were collected, and after quality control, 1003 were included. 56.2% (564/1003), 53.2% (534/1003), and 67.4% (676/1003) individuals had anxiety, depression, and sleep disorders. Differences in age, gender, and education level were observed (P <0.05). Subgroup analysis showed similar demographic trends. Univariate and multivariate regression analysis found age negatively correlated with anxiety (OR=0.98, 95%CI=0.97-0.99, P =0.02) and depression (OR=0.98, 95%CI=0.96-0.99, P <0.001), but positively correlated with sleep disorders (OR=1.03, 95%CI= 1.01-1.05, P < 0.001); males are less prone to anxiety (OR=0.68, 95%CI=0.52-0.88, P =0.004) and sleep disorders (OR=0.72, 95%CI: 0.55-0.94, P =0.02); university degree is more susceptible to depression (OR=1.36, 95%CI=1.04-1.77, P =0.02) and anxiety (OR=1.45, 95%CI=1.11-1.89, P =0.007). RCS analysis suggested a linear relationship between the age and affective disorders among different population. Conclusion: Young individuals, female, and those with higher education are more vulnerable to mental health, warranting increased attention. [ABSTRACT FROM AUTHOR]

Introduction: This study aimed to estimate prevalence and incidence of attention deficit/hyperactivity disorder (ADHD) and comorbid relationships between ADHD and other psychiatric disorders in Japan. Methods: Using the real-world JMDC Claims Database, we conducted a cross-sectional study (analysis years 2017–2021) and retrospective cohort study (observation 2 years before/after the initial ADHD diagnosis; data collection 2005–2021; enrollment 2017–2019). Patients were male or female, aged 0–57 years. Cross-sectional study patients had an ADHD or other psychiatric disorder diagnosis (with or without medication) and were continuously registered in each analysis year; retrospective study patients had an ADHD diagnosis and ≥2 years' observation before and after diagnosis. Endpoints were annual prevalence and incidence of ADHD in Japan, prevalence and risk ratio of each psychiatric comorbidity in patients with ADHD, prevalence and risk ratios of ADHD in patients with each psychiatric comorbidity, and prevalence of psychiatric disorders before/after the initial ADHD diagnosis. Results: ADHD prevalence in children/adolescents and adults increased each year from 2017 to 2021. Prevalence in boys was 3.5–4.1 times higher than in girls. Prevalence in adults was lower than in children/adolescents, with a small sex difference. ADHD was highly comorbid with various psychiatric disorders. In 2019, the most common comorbidity in children/adolescents with ADHD was autism spectrum disorder (ASD; 54.4%); in adults, it was mood disorders (60.9%). ADHD prevalence in patients with various psychiatric disorders was higher than in the control population. ADHD prevalence was highest in patients with oppositional defiance disorder among both children/adolescents and adults (77.2% and 69.2%, respectively). In the retrospective cohort study (N = 14,940), the most common psychiatric disorders diagnosed prior to ADHD diagnosis were ASD in children/adolescents (33.9% of patients), and mood disorders and sleep disorders in adults (36.9% and 23.8% of patients, respectively). Discussion: ADHD was comorbid with various psychiatric disorders in Japan. In children and adolescents with ADHD, ASD was often diagnosed prior to ADHD. Psychiatric disorders, especially mood disorders and sleep disorders, were frequently diagnosed prior to the initial ADHD diagnosis in adults. The likelihood of comorbid ADHD should be considered when diagnosing adult patients with psychiatric disorders. [ABSTRACT FROM AUTHOR]

Background: Weighted blanket is an emerging non-pharmacotherapy for sleep disorders, but its effect on sleep among relatively healthy adults with insomnia remains uncertain. This study aimed to evaluate whether weighted blankets could better improve sleep quality and sleep-related symptoms among adults with insomnia. Methods: In a prospective, pilot randomized controlled trial conducted in three tertiary hospitals in China, participants with clinical insomnia were randomized (1:1) to receive weighted blanket intervention or normal blanket intervention for 1 month by random-number tables. The primary outcomes were sleep quality assessed with Pittsburgh Sleep Quality Index (PSQI) and insomnia severity assessed with Insomnia Severity Index. Subjective outcomes were measured at baseline, 1 week, and 1-month post-intervention. Sleep was also objectively monitored by actigraphy. We did analysis by intention to treat. Results: A total of 102 participants were randomly assigned to receive weighted blanket intervention (n = 52) or normal blanket intervention (n = 50). 95 (93.1%) participants completed the follow-up, and 7 (6.9%) participants dropped out of the study. The weighted blanket group had significant improvements in sleep quality compared to the normal blanket group after 1 month of intervention (changes in the mean [SD] of PSQI score: -4.1 [4.1] vs. -2.0 [3.2], P = 0.006). Similar results were observed for daytime sleepiness, stress, anxiety, fatigue, and bodily pain (all P < 0.05). Recordings from actigraphy showed a decrease in the mean (SD) of the number of awakenings in weighted blanket group (-1.4 [9.5]) and an increase in normal blanket group (+ 1.0 [7.9]) (P = 0.280). No severe adverse events occurred. Conclusions: Weighted blanket might be an effective, safe and promising non-pharmacotherapy tool for improving sleep-related symptoms among adults with insomnia, although validation with a larger sample size is needed. Trial registration: Chinese Clinical Trial Registry: ChiCTR2300078011, date of registration: 11/27/2023, retrospectively registered. [ABSTRACT FROM AUTHOR]

Background: Previous studies have shown that overall sleep quality among Chinese nurses is relatively low, with a sleep disorder prevalence rate of approximately 66.4%. Against the backdrop of healthcare reforms, China has been striving to improve the mental health and sleep quality of nurses. Stress mindset can influence how individuals respond to stress, but there is limited research on how stress mindset affects nurses' sleep quality. This study aims to explore the impact of stress mindset on sleep quality among nurses, as well as the mediating roles of stress overload and anxiety in this relationship. Methods: The study was conducted online using a questionnaire from February 18 to February 22, 2024. It utilized the Stress Mindset Measure (SMM), the Stress Overload Scale-Short (SOS-S), the Generalized Anxiety Disorder 7-item scale (GAD-7), and the Pittsburgh Sleep Quality Index (PSQI) to survey 441 nurses in three regions of China: Chongqing, Hunan, and Shandong (M = 34.39, SD = 7.82, 95.7% female). A chain mediation model was employed to examine the mediating roles of stress overload and anxiety in the relationship between stress mindset and sleep quality. Results: The participants' average sleep quality score was 7.18 ± 3.47. Nurses' stress mindset was significantly negatively correlated with both stress overload and anxiety, and significantly positively correlated with sleep quality. Stress overload was significantly positively correlated with anxiety and significantly negatively correlated with sleep quality. Anxiety was also significantly negatively correlated with sleep quality. The direct effect of nurses' stress mindset on sleep quality was significant (effect size = -0.10, 95% CI: -0.19 to -0.01), as were the indirect effects through stress overload (effect size = -0.05, 95% CI: -0.11 to -0.01) and anxiety (effect size = -0.09, 95% CI: -0.13 to -0.05), along with their chain mediation effect (effect size = -0.10, 95% CI: -0.14 to -0.06). Conclusion: Our study demonstrates that a higher level of nurses' stress mindset is associated with better sleep quality, with stress overload and anxiety mediating this relationship. A positive stress mindset helps nurses cope more effectively with professional challenges and reduces anxiety, leading to improved sleep quality. Healthcare institutions should therefore prioritize fostering positive stress mindsets in nurses, encouraging regular psychological training and workshops to support the development of effective coping strategies.

Introduction: Children and adolescents treated in specialty mental health services are more likely to have sleep disturbances than those without mental health problems. Few studies have investigated the relationship between sleep and psychopathology in broad clinical samples of children. We examined the relationship between sleep disturbance and age on internalizing and externalizing psychopathology in a sample who sought treatment at children's mental health centers. Methods: Secondary data analyses were completed on a sample of children (N = 13,472; aged 4 to 18; 55% male) from 39 children's mental health agencies in Ontario, Canada, who completed a semi-structured assessment, the interRAI Children and Youth Mental Health (ChYMH). A split-half sample approach was utilized (S1 n = 6,773, S2 n = 6,699). Hierarchical regressions examined the effects of sleep disturbances (i.e., difficulty falling asleep, staying asleep, night waking, bedtime resistance, falling asleep during the day) on internalizing and externalizing symptoms, above and beyond established child- (i.e., age, sex, sensory sensitivity, pain) and family-level variables (family functioning, caregiver distress, parenting strengths). Age was tested as a moderator for sleep disturbances on both outcome variables. Results: Overall, 6.7% of children had clinically significant sleep disturbance scores (≥10 out of 16) on the interRAI ChYMH. In both samples, sleep disturbances predicted internalizing (S1 ΔR2 = 10%, S2 ΔR2 = 10%) and externalizing symptoms (S1 ΔR2 = 2%, S2 ΔR2 = 1%), above and beyond child and family variables. Age moderated the relationship between sleep disturbances and internalizing symptoms (S1 ß = 0.07; S2 ß = 0.07; ΔR2 = 0.004 in both samples), but not externalizing symptoms; sleep disturbance was more strongly related to internalizing symptoms amongst adolescents (ß = 0.98) than children (ß = 0.62). Discussion: The relationship between sleep and internalizing symptoms appears to change as children move through development. Further, sleep was a stronger predictor of internalizing problems in adolescents than children, suggesting an additional focus of clinician efforts in this age group. These findings strengthen the importance of routine assessment of sleep, as is done with the interRAI ChYMH. [ABSTRACT FROM AUTHOR]

Background: This study aims to elucidate characteristics of the symptom network of work–family conflict (WFC) and sleep disorders among Chinese correctional personnels while accounting for job burnout as a possible confounder. Method: A total of 472 correctional personnel were included. Their WFC, sleep disorders, and job burnout were measured using a Chinese version of Work–Family Conflict Scale (WFCS), the Athens Insomnia Scale (AIS), and a revised Chinese version of Maslach Burnout Inventory‐General Survey (MBI‐GS), respectively. Central symptoms and bridge symptoms were respectively identified based on centrality indices and bridge centrality indices. Network stability was examined using the case‐dropping procedure. Results: Daytime condition (strength = 0.01) and strain‐based work interference with family (WFCs, strength = 1.45) symptoms had the highest centrality values in the WFC‐sleep disorder network structure, which were also identified as two bridge symptoms. Emotional exhaustion, daytime condition, and WFCs appeared to be potential bridge symptoms in the WFC–sleep disorder–burnout network structure. Conclusions: In this study, among Chinese correctional personnel, daytime conditions, and WFCs were found to be central symptoms in the WFC–sleep disorder network structure, with emotional exhaustion as the bridge symptom in the WFC–sleep disorder–burnout network structure. We encourage relevant organizations to provide timely and effective education and guidance for regulatory personnel regarding these bridge symptoms. Subsequent research should follow up to assess the impact of relevant interventions on symptoms in the WFC–sleep disorder–burnout network, thereby advocating for the mental and physical health of correctional personnel.

Summary Although emerging research suggests insomnia is a significant problem among people with eating disorders, little is known about how insomnia symptoms may serve as risk factors for eating disorder symptoms, treatment outcome, and relapse. University students with non‐low‐weight eating disorders (N = 89) completed a mobile guided self‐help cognitive behavioural intervention for eating disorders. Insomnia and binge‐eating symptoms were assessed at pre‐treatment and end‐of‐treatment using the Insomnia Severity Index and Eating Pathology Symptoms Inventory. Multiply imputed datasets were used to test associations between insomnia and binge eating before, during and after treatment. Insomnia was positively associated with binge‐eating symptoms prior to treatment (r = 0.47). Baseline insomnia symptoms were associated with binge‐eating symptoms at end‐of‐treatment (est = 0.269). Eating disorder treatment modestly reduced insomnia (d = −0.38); however, about half of people with clinically significant insomnia prior to treatment remained symptomatic. Insomnia symptoms and binge‐eating symptoms did not change concurrently during treatment. Overall, results support an association between insomnia and binge eating. Although eating disorder treatment may impact insomnia, many individuals remained symptomatic for sleep problems, suggesting the need for follow‐up treatments, such as cognitive behavioural therapy for insomnia, or the development of integrated insomnia–eating disorder treatments. Future studies are needed to examine causal links between insomnia and eating disorder symptoms, and test if insomnia predicts relapse after eating disorder treatment. [ABSTRACT FROM AUTHOR]

Objective: To determine the difference in the prevalence of lymphopenia in the American population according to demographic characteristics, body mass index (BMI) and living habits. Methods: A total of 33,365 participants aged over 1 were included in the 2009–2018 National Health and Nutrition Survey (NHANES). All analyses used weighted samples and considered the layering and clustering of the design. Results: Using white participants as a reference, the prevalence of lymphopenia in Mexican-American participants was significantly lower than that of white participants (P = 0.018). There was no significant difference in the prevalence of lymphopenia between black participants (P = 0.376) and white participants. The prevalence of lymphopenia was 1.81% (95%CI, 1.53%-2.10%) for white participants, 1.08% (95%CI, 0.78%-1.39%) for black participants, and 0.42% (95%CI, 0.17%-0.68%) for Mexican-American participants. The prevalence of lymphopenia increases with age, reaching a peak of 6.84% among elderly participants aged 75 and above. In terms of the gender difference, the prevalence of lymphopenia in men is significantly higher than that in women (P<0.001). Individuals who smoke (P<0.001), consume alcohol (P = 0.032), engage in regular exercise (P = 0.031), have sleep disorders (P<0.001) and those classified as having an unhealthy weight (P<0.001) had a higher average lymphocyte count. The prevalence of lymphopenia in participants with sleep disorders is significantly higher than those without sleep disorders (P = 0.014). However, no significant differences were observed among the classification variables of smoking, drinking, exercise, and BMI. Conclusion: In the diagnosis and treatment of lymphopenia, clinicians should consider the influence of factors such as race, gender, age, sleep disorders, and other unhealthy lifestyle habits to improve the accuracy of diagnosis and treatment, thereby reducing the high mortality risk associated with lymphopenia. Consequently, we propose a novel perspective that the diagnosis and treatment of lymphopenia should be tailored to the lymphocyte levels of specific subpopulations, rather than applying a generalized approach.

Introduction: For most people, gender identity is consistent with biological sex and such people are called cisgender. People in whom such a relationship does not occur or occurs to a lesser extent are referred to as gender non-conforming—and these include transgender, non-binary, agender and gender-fluid people. These individuals are usually affected by minority stress, which, combined with the circumstances of the pandemic and Russian aggression against Ukraine, may have led to mental disorders and sleep disorders in this population. The aim of the study was to analyze the symptoms of anxiety, depression and insomnia in a group of Polish youth during the Covid-19 pandemic and the outbreak of the war in Ukraine, taking into consideration gender differences, including non-binary gender. Methods: The study involved 1621 secondary school students aged 14 to 19, the average age was 16.73 ± 1.35, including 857 girls, 690 boys and 74 people who defined their gender as non-binary. A set of questionnaires for the Diagnosis of Depression in Children (CDI 2), the State-Trait Anxiety Inventory (STAI), the X-1 subscale, The Athens Insomnia Scale (AIS) and an original questionnaire of sociodemographic data were used in research. Results: Analyzing the results obtained in the study group, the respondents scored an average of 17.99 ± 9.55 points in the assessment of depressive symptoms. After division into groups taking into account gender, the corresponding score was 19.69 ± 9.40 points for girls, 15.03 ± 8.68 for boys and 25.86 ± 9.91 for non-binary people. The difference was statistically significant (p = 0.000) in all three study groups. In the anxiety symptoms assessment, the respondents scored an average of 46.92 ± 11.67 points. After division into gender groups, the corresponding score was 49.21 ± 11.12 points for girls, 43.39 ± 11.47 for boys and 53.39 ± 10.41 for non-binary people. The difference was statistically significant (p = 0.000) in all three study groups. Analyzing the results obtained in The Athens Insomnia Scale (AIS), the average score was 8.31 ± 4.58 points, which allows to evaluate sleep onset as a norm. After dividing into groups, the results were 8.95 ± 4.55 points, respectively for girls, 7.19 ± 4.21 points for boys and 11.35 ± 5.43 for non-binary people, the difference was significant in terms of comparisons between all statistically tested groups. The analysis of the relationships between the studied variables was presented for each gender separately. Statistically significant positive correlations were found between the results obtained on the scale assessing depressive symptoms (CDI-2) and anxiety symptoms (STAI-X1) and the results obtained on the AIS scale. Conclusions: Among the studied group of teenagers, the highest intensity of depressive symptoms is demonstrated by non-binary people, followed by females, and finally by males. Similar results were obtained in the assessment of anxiety symptoms. The non-binary group achieved results indicating sleep disorders, while the cisgender group's results of sleep onset were borderline normal. Whatsmore, the greater the severity of depressive and anxiety disorders, the greater the sleep disorders in all study groups, regardless of gender. [ABSTRACT FROM AUTHOR]

Obstructive sleep apnea (OSA) syndrome is a prevalent form of respiratory sleep disorder, with an increasing prevalence among children. The consequences of OSA include obesity, diabetes, cardiovascular disease, and neuropsychological diseases. Despite its pervasive impact, a significant proportion of individuals especially children remain unaware that they suffer from OSA. Consequently, there is an urgent need for an accessible diagnostic approach. In this study, we conducted a bioinformatic analysis to identify potential biomarkers from a proteomics dataset comprising serum samples from children with OSA in the progression stage. In the Gene Set Enrichment Analysis (GSEA), we observed that the complement and immune response pathways persisted throughout the development of OSA and could be detected in the early stages. Subsequent to soft clustering and WGCNA analysis, it was revealed that the Hippo pathway, including ITGAL and FERMT3, plays a role in mild OSA. The analysis revealed a significant alteration of the complement and coagulation pathways, including TFPI and MLB2, in moderate OSA. In severe OSA, there was an association between hypoxia and the extracellular matrix (ECM) receptor interaction and collagen binding. In summary, it can be posited that the systemic inflammation may persist throughout the progression of OSA. Furthermore, severe OSA is characterized by abnormal vascular endothelial function, which may be attributed to chronic hypoxia. Finally, four potential biomarkers (ITGAL, TFPI, TTR, ANTXR1) were identified based on LASSO regression, and a prediction model for OSA progression was constructed based on the biomarkers.

Bruxism is a complex orofacial behavior that can occur during sleep or wakefulness, characterized by the involuntary grinding or clenching of teeth, involving repetitive activity of the jaw muscles. Its etiology is multifactorial, influenced by genetic, psychological, physiological, and lifestyle factors. While the mild bruxism may not necessitate treatment, severe bruxism can lead to significant consequences, including tooth damage, jaw pain, fatigue, and headaches. The bruxism has been associated with medical conditions, such as stress, anxiety, sleep disorders, and various neurological disorders; however, the exact pathophysiology remains elusive. Although the central nervous system is strongly implicated in the development of bruxism, specific neural substrates have not yet been conclusively established. Furthermore, there is evidence to suggest that individuals with bruxism may exhibit neural plasticity, resulting in the establishment of distinct neural circuitry that control the jaw movements. The application of various neurophysiological techniques in both clinical and pre-clinical studies provides valuable insights into the neural mechanisms underlying bruxism. This review aims to comprehensively examine the current literature on the neural pathways involved in bruxism, with the goal of improving the clinical approach and therapeutics for this condition. A deeper understanding of the neural circuitry controlling bruxism holds the potential to advance future treatment approaches and improve the management of patients with bruxism.

ABSTRACT: Background: Multiple sclerosis (MS) is considered the most prevalent neurological disorder in young adults with many patients manifesting sleep-related disorders (SRD) due to its pathomechanisms. This is subsequently reflected in patients' quality of life and physical activities. Material and Methods: This is a cross-sectional study at a tertiary care center. Patients diagnosed with MS were enrolled, and assessment of their sleep patterns and related disorders were measured using pre-validated scales. A questionnaire consisting of 38 items was used, and the obtained data were analyzed using RStudio software. Results: A total of 260 patients participated in the study. Most participants were aged 31–40 (n = 112) with a mean age of 36.49 ± 8.41 (age range: 18–56 years). The most used medications were rituximab (27%) and ocrelizumab (25%). Shapiro–Wilk Test was significant (P = 0.04) and just below the significance level of α = 0.05, suggesting potential significant deviation in the distribution of age. Logistic regression model was applied, and the female probability of sleeping more than six hours was 3.60 times the probability of sleeping six hours or less. Conclusion: Sleep quality is multifaceted and requires intensive investigation in patients with chronic disorders including MS. In this study, several novel data have been presented in a population that has very little literature data. [ABSTRACT FROM AUTHOR]

Objective: Despite the historical neurological use of Withania somnifera, limited evidence supports its efficacy for conditions like anxiety and insomnia. Given its known anti‐stress properties, this review evaluated its safety and efficacy for anxiety and insomnia. Methods: We searched Medline, Cochrane Library, and Google Scholar until August 2023 for randomized controlled trials (RCTs) comparing W. somnifera to placebo in patients with anxiety and/or insomnia. Outcome measures included changes in anxiety levels via the Hamilton Anxiety Scale (HAM‐A), Sleep Onset Latency (SOL), Total Sleep Time (TST), Wake After Sleep Onset (WASO), Total Time in Bed (TIB), Sleep Efficiency (SE), and Pittsburgh Sleep Quality Index (PSQI) score. We utilized a random‐effect model for pooling Mean Differences (MD) with a 95% Confidence Interval (CI). Heterogeneity was assessed through sensitivity and subgroup analysis, and the quality of RCTs was evaluated using the Cochrane revised risk of bias tool. Results: Pooled results from five RCTs (n = 254) demonstrated that W. somnifera significantly reduced HAM‐A scores (MD = −5.96; [95% CI −10.34, −1.59]; P = 0.008; I2 = 98%), as well as sleep parameters such as SOL, TST, PSQI, and SE, but not WASO and TIB. Conclusion: While W. somnifera extracts yielded promising results, further research with larger sample sizes is needed to confirm its effects on anxiety and insomnia. [ABSTRACT FROM AUTHOR]

Background: Currently, no standard scale has been validated to assess overall severity of RBD symptoms in the home environment. We aimed to evaluate the psychometric properties of the International RBD Severity Scale (IRBD-SSS), a new tool designed by the International RBD Study Group. Methods: Two versions of the IRBD-SSS were created, one for the patient (IRBD-SSS-PT) and another for the bedpartner (IRBD-SSS-BP), both consisting of 3 components, namely vocalizations, body movements and injury, with a fourth component (patient version only) evaluating dream content. To score each dimension, the frequency and severity/impact of behaviors during the previous month are multiplied. Psychometric properties of the IRBD-SSS were assessed, including reproducibility. Results: A total of 188 subjects including n = 132 RBD patients (n = 94 isolated RBD and n = 38 symptomatic RBD) and n = 52 bedpartners were enrolled from eight Sleep centers across France and Italy. Participants completed the scale at baseline and after one week. Acceptability of the scale was excellent in patients (97%) and bedpartners (98%). Internal consistency was acceptable for IRBD-SSS-PT (Cronbach α = 0.75) while slightly low for IRBD-SSS-BP (Cronbach α = 0.49). Concurrent validity was good for both patient (r = 0.70;p < 0.001, see Figure) and bedpartner (r = 0.69;p < 0.001) IRBD-SSS. Reproducibility was high for IRBD-SSS-PT (Lin's coefficient of agreement = 0.85 [0.81;0.90]) and good for the IRBD-SSS-BP (0.79 [0.68;0.90] (p < 0.001). Conclusions: Both the patient and bedpartner versions of the IRBD-SSS showed excellent acceptability, acceptable internal consistency, good external validity and high reproducibility. IRBD-SSS is a useful tool to test the severity of RBD symptoms in clinical settings and clinical trials. Trial registration: NCT04071899. [ABSTRACT FROM AUTHOR]

Objectives: The objective is to assess the interconnectedness of a network of health‐related quality of life (HRQoL) variables among people with HIV (PHIV) to identify key areas for which clinical interventions could improve HRQoL for this population. Methods: Between 2021 and 2023, we carried out a cross‐sectional study within the Spanish CoRIS cohort. We conducted a weighted and undirected network analysis, which examines complex patterns of relationships and interconnections between variables, to assess a network of eight HRQoL dimensions from the validated Clinic Screening Tool for HIV (CST‐HIV): anticipated stigma, psychological distress, sexuality, social support, material deprivation, sleep and fatigue, cognitive problems and physical symptoms. Results: A total of 347 participants, predominantly male (93.1%), currently working (79.0%), self‐reported homosexual (72.6%) and college‐educated (53.9%), were included in the study. Psychological distress showed the highest centrality in the network, indicating its strong connections with sleep and fatigue, cognitive problems and social support within the HRQoL network. Conclusions: Psychological distress, sleep and fatigue, cognitive issues and social support were identified as key factors in an HRQoL network, indicating that interventions focused on these areas could significantly enhance overall well‐being.

Background: The Developmental Origins of Health and Disease Hypothesis (DOHaD) suggests prenatal alcohol exposure (PAE) should have implications for adult physical and mental health. Since the health profile of older adults with PAE and diagnoses of fetal alcohol spectrum disorder (FASD) is unknown, the current study evaluates self‐reported health problems of midlife adults with and without a history of PAE to describe these outcomes. Methods: Participants (N = 357) recruited from longitudinal cohorts in Atlanta, GA and Seattle, WA completed a health survey assessing a range of physical conditions. Initial analysis compared the frequency of conditions between alcohol‐exposed and nonexposed groups. To identify patterns within groups, 10 problem areas were subjected to latent class analysis (LCA). Finally, the direct effect of PAE on health outcomes was evaluated using multilevel modeling, controlling for effects of other factors. Results: Compared with unexposed controls, individuals with PAE reported significantly higher frequencies of problems with hearing, dentition, heart, cancer, gastritis, kidney stones, bladder, diabetes, thyroid, skin, and seizures. LCA found that controls yielded two classes, with 45% reporting sleep and vision problems and 55% reporting sleep, vision, cardiovascular, endocrine, immune, and dental problems. The PAE group yielded three classes, with 13% endorsing few health problems, 43% reporting sleep, vision, immune, and dental problems, and 43% reporting sleep, vision, cardiovascular, urinary, endocrine, skin, immune, dental, and gastrointestinal problems. With multivariate analysis, controlling for other influences, PAE was associated directly with hearing, urinary, dental, and gastrointestinal problems. A similar pattern was found for alcohol‐exposed individuals who did and did not meet criteria for fetal alcohol syndrome (FAS). Discussion: Patients affected by alcohol may report greater frequency and range of health adversity. That PAE was only uniquely associated with a limited set of problems suggests that many health outcomes in midlife result from an initial vulnerability potentiated by postnatal stress resulting from other associated factors.

Background: Anti‐IgLON5 encephalitis was a rare neurological and heterogeneous disorder, which was mainly found in adults. Epileptic seizures related to anti‐IgLON5 disease were rarely reported. Methods: Neural antibodies associated with autoimmune encephalitis in serum and cerebrospinal fluid (CSF) were tested using cell‐based assays (CBA) with immunofluorescence double staining. The antibodies in serum were further confirmed by tissue‐based assay (TBA) with rat brain and kidney tissue. Results: We reported a pediatric case presented with epileptic seizures, cognitive impairments, and sleep disorders. Autoantibody screening showed anti‐IgLON5 antibody IgG (1:100+) and anti‐NMDAR antibody IgG (1:10+) in the serum. She was diagnosed as anti‐IgLON5 encephalitis. Her conditions improved rapidly by treated with intravenous immunoglobulin and high dose intravenous methylprednisolone. Conclusion: We described the second pediatric case with anti‐IgLON5 encephalitis, who was also the first presented with epileptic seizures as the initial presentation. Anti‐IgLON5 encephalitis might have mild manifestations. For patients with new onset seizures associated with cognitive impairments and sleep disturbances, anti‐IgLON5 antibody should be tested as early, even in children. [ABSTRACT FROM AUTHOR]

Serotonin is a monoamine neurotransmitter that plays a main role in regulating physiological and cognitive functions. Serotonergic system dysfunction is involved in the etiology of various psychiatric and neurological disorders. Therefore, the present study was designed to investigate the effects of early‐life serotonin depletion on cognitive disorders caused by sleep deprivation. Serotonin was depleted by para‐chlorophenylalanine (PCPA, 100 mg/kg, s.c.) at postnatal days 10–20, followed by sleep deprivation‐induced through the multiple platform apparatus for 24 h at PND 60. After the examination of the novel object recognition and passive avoidance memories, the hippocampi and prefrontal cortex were dissected to examine the brain‐derived neurotrophic factor (BDNF) mRNA expression by PCR. Our findings showed that postnatal serotonin depletion and sleep deprivation impaired the novel object recognition and passive avoidance memories and changed the BDNF levels. In the same way, the serotonin depletion in early life before sleep deprivation exacerbated the harmful effects of sleep deprivation on cognitive function and BDNF levels. It can be claimed that the serotonergic system plays a main role in the modulation of sleep and cognitive functions. [ABSTRACT FROM AUTHOR]

Background: Residents of assisted living facilities (ALF) transfer to a nursing home when they require a higher level of care, but limited research has examined risk factors for transfer to a nursing home. The aims of this study were to identify (1) baseline factors associated with transfer to a nursing home and (2) time‐varying factors associated with transfer to a nursing home over 8 years, using a national dataset from the National Health Aging Trends Study (NHATS). Methods: NHATS participants were included in this study if they: (1) resided in ALF from Round 1 (2011) through Round 8 (2018); (2) completed the sample person (SP) interview at baseline; (3) were admitted to ALF at age 65 years or older. We conducted Cox proportional hazards regression to examine candidate predictors (difficulty with basic activities of daily living (ADL), chronic conditions, hospitalization, sleep disturbances, mental health, physical performance, self‐reported health, participation in social and physical activity, and sociodemographic) associated with transfer to a nursing home. Employing backward elimination, we built parsimonious final models for analysis. Results: The analytic sample included 970 participants of whom 143 transferred to nursing homes over 8 years. Those who had a better physical performance at baseline (HR = 0.83, 95% CI = 0.79–0.88) and were college educated (HR = 0.58, 95% CI = 0.36–0.92) demonstrated a significantly lower risk for transfer to a nursing home over 8 years. Residents who maintained physical activity (HR = 0.56, 95% CI = 0.37–0.86), better physical performance (HR = 0.87, 95% CI = 0.80–0.94), and difficulty with fewer basic ADLs (HR = 1.13, 95% CI = 1.02–1.26) were at lower risk for transfer to a nursing home over 8 years. Conclusions: Our findings can be used to identify older adults in ALFs at risk of transfer to a nursing home. Strategies to promote physical function and physical activity could avoid/delay the need to transfer. Helping older residents to age in place will have important health and economic benefits.

BACKGROUND: Traumatic brain injury (TBI) is a hallmark of wartime injury and is related to numerous sleep wake disorders (SWD), which persist long term in veterans. Current knowledge gaps in pathophysiology have hindered advances in diagnosis and treatment. OBJECTIVE: We reviewed TBI SWD pathophysiology, comorbidities, diagnosis and treatment that have emerged over the past two decades. METHODS: We conducted a literature review of English language publications evaluating sleep disorders (obstructive sleep apnea, insomnia, hypersomnia, parasomnias, restless legs syndrome and periodic limb movement disorder) and TBI published since 2000. We excluded studies that were not specifically evaluating TBI populations. RESULTS: Highlighted areas of interest and knowledge gaps were identified in TBI pathophysiology and mechanisms of sleep disruption, a comparison of TBI SWD and post-traumatic stress disorder SWD. The role of TBI and glymphatic biomarkers and management strategies for TBI SWD will also be discussed. CONCLUSION: Our understanding of the pathophysiologic underpinnings of TBI and sleep health, particularly at the basic science level, is limited. Developing an understanding of biomarkers, neuroimaging, and mixed-methods research in comorbid TBI SWD holds the greatest promise to advance our ability to diagnose and monitor response to therapy in this vulnerable population.

BACKGROUND: Concussion, also known as mild traumatic brain injury (mTBI), is a condition with unique ties to military service. Service members (SMs) are inherently at a higher risk for concussive injuries due to the intense physical training environment and combat operational tempo required to serve. The Traumatic Brain Injury Center of Excellence (TBICoE) is the US Department of Defense authority on this condition and provides a thorough approach to management of concussion and associated symptom sequela. OBJECTIVES: This article seeks to review the TBICoE approach to the management and rehabilitation of military SMs with mTBI, and highlight resources available to military medical providers. METHODS: The authors reviewed evidence and TBICoE resources to provide this comprehensive overview of the TBICoE approach to management and rehabilitation of concussion in military SMs. RESULTS: A progressive return to activity protocol in conjunction with symptom-guided management of common post-concussive sequelae, including headache, vestibular and oculomotor issues, sleep dysfunction, cognitive rehabilitation, and behavioral health comorbidities are essential for concussion management in the acute, post-acute and chronic phases of injury. CONCLUSION: The TBICoE approach to the rehabilitation of military SMs is comprehensive, and includes initial management with a stepwise return to duty protocol and an objective return to duty screening. The mainstays of treatment for SMs with post-acute and chronic post-concussion symptoms are headache management, vestibular and oculomotor rehabilitation, sleep interventions, cognitive rehabilitation, and early intervention for behavioral health comorbidities. These evidence-based strategies may be applied in the treatment of SMs in the US and internationally. [ABSTRACT FROM AUTHOR]

Introduction The leading cause for medical evacuation from the U.S. Central Command area of responsibility is because of mental health conditions. The In-Theater Mental Health Assessment (ITMHA) is a DoD-required screening of deployed personnel. It is vital to examine the efficacy of ITMHA's potential to significantly impact the mental health outcomes of service members. Materials and Methods All ITMHA results of individuals in 2 deployed Army battalions along with a brigade headquarters deployed to U.S. Central Command between October 2022 and October 2023 were collected and analyzed. Descriptive statistics were used to characterize the results of the ITMHA. Results Of 670 deployed service members, 157 (23%) scored positive on ITMHA. Ten service members were referred for additional mental health evaluation. The remaining 147 (22%) service members who scored positive were not referred because of a lack of significant impairment or were already engaged in mental health services. One service member in the study was evacuated because of a mental health condition. The most common major life stressors identified were family/relationship issues, sleep problems, and mental health concerns. Conclusions The number of deployed personnel identified through the ITMHA as requiring mental health care was modest. The ITMHA has multiple limitations that, if addressed, will improve its utility to mitigate mental health decline in the expeditionary environment. [ABSTRACT FROM AUTHOR]

OBJECTIVE: As pediatric mortality improves, approaches to pediatric critical care now focus on understanding long-term implications of survivorship on patients and families. We aimed to characterize how patients recall time spent sedated and recovering to identify areas for improvement in patient outcomes. METHODS: We undertook qualitative analysis using semistructured interviews of pediatric patients requiring extra-corporeal support in our intensive care units from 2018 to 2023. All patients were English-speaking, >12 years old at time of hospitalization, and able to communicate at an age-appropriate level. Priority sampling was given to those with more recent hospitalizations to improve recall. Interviews were recorded and transcribed before thematic, inductive analysis. RESULTS: Forty-one patients met inclusion criteria; 14 patients were enrolled before achieving thematic saturation. Several themes emerged, centering on cognitive, physical, and socioemotional experiences during and after hospitalization. Notable findings include profound awareness under sedation, impaired sleep, challenges with communication, physical discomfort, frustration with activities of daily living limitations, and gratitude for provider and family presence. Postdischarge, patients highlighted persistent memory, concentration, sleep, and physical impairments, as well as emotional processing of their illness and mortality. CONCLUSIONS: Our findings describe how pediatric critical illness impacts short and long term cognitive, physical, and socioemotional outcomes for children in the ICU. Future research is necessary to study if there are specific, modifiable factors in patients' care that impacts their experience of critical illness, such as specific medication choices, diagnoses, communication styles, or physical and speech therapy interventions.

Aim: To assess self‐reported parasomnias in patients with sleep disorders and explore relationships with psychiatric illness, comorbidities, subjective sleep assessments, and polysomnographic study results. Methods: Results from intake questionnaires and polysomnographic assessments, collected from 240 sleep centers across 30 US states between 2004 and 2019, were analyzed retrospectively. Of 540,000 total patients, 371,889 who answered parasomnia‐specific questions were included. Patients responding "often" or "always" to parasomnia‐specific questions were considered "symptom‐positive," whereas a "few times" or "never" were considered "symptom‐negative" (controls). Results: The study sample was 54.5% male with mean age 54 years (range, 2–107 years). Frequencies for the different parasomnias were 16.0% for any parasomnia, 8.8% for somniloquy, 6.0% for hypnagogic hallucinations, 4.8% for sleep‐related eating disorder, 2.1% for sleep paralysis, and 1.7% for somnambulism. Frequent parasomnias were highly associated with diagnosed depression (odds ratio = 2.72). All parasomnias were associated with being younger and female and with symptoms of depression, anxiety, insomnia, restless legs, pain, medical conditions, fatigue, and sleepiness. Associations with objective sleep metrics showed characteristics of consolidated sleep and differentiated weakly between nonrapid eye movement sleep and rapid eye movement sleep parasomnias. Machine learning accurately classified patients with parasomnia versus controls (balanced accuracies between 71% and 79%). Benzodiazepines, antipsychotics, and opioids increased the odds of experiencing parasomnias, while antihistamines and melatonin reduced the odds. Z‐drugs were found to increase the likelihood of a sleep‐related eating disorder. Conclusion: Our findings suggest that parasomnias may be clinically relevant, yet understudied, symptoms of depression and anxiety. Further investigation is needed to quantify the nature of multimorbidity, including causality and implications for diagnosis and treatment. [ABSTRACT FROM AUTHOR]

Objectives Sleep disturbances in later life are prevalent and can profoundly impact health and well-being. However, whether and how trajectories of sleep disturbances vary as people age by gender and across age cohorts remains unexplored. This study applies an integrated theoretical framework to understand gender-specific trajectories of sleep disturbances over time and how they vary by cohort. Methods Accelerated longitudinal data from the Health and Retirement Study (N  = 20,947; M  = 8,562, F  = 12,385) was analyzed to investigate gender-specific trajectories of sleep disturbances and potential cohort variations. Weighted growth curve model was applied with sociodemographic and health-related variables. Men and women were analyzed separately. Results Results showed that sleep disturbances increased with age in men, but not in women. Also, younger cohorts of men increased sleep disturbances over time at a slower rate than older cohorts. Among men, health profiles accounted for the association between age and sleep disturbances. Among men and women, younger cohorts started with higher levels of sleep disturbances around midlife. When examining specific types of sleep disturbance separately, having trouble falling asleep was the type that drove the observed patterns in men. For women, there was no association between age and any individual type of sleep disturbance. Discussion This study shows that men, rather than women, tend to experience increasing sleep disturbances with age, with some variations across cohorts. These findings imply that different strategies for men and women and targeted timing over the life course would be most effective at promoting sleep health in American men and women.

Objectives: This study aimed to explore the relationship between breakfast skipping and its effects on sleep disorders, mental health, and health-related quality of life among Korean adults. Methods: Utilizing data from the 2018 Korea Community Health Survey, this cross-sectional analysis included 173,272 adults aged 19 years and older. Instruments used for assessment included the Patient Health Questionnaire-9 for depression, the EuroQol 5-dimension (EQ-5D) for health-related quality of life, and the Pittsburgh Sleep Quality Index for sleep disorders. The complex sample logistic regression analysis was employed to adjust for potential confounders. Results: Breakfast skipping was found to be significantly associated with delayed mid-sleep time, an increased propensity for daytime sleepiness, and a notable decline in sleep quality. Additionally, it was linked to a significant increase in depression risk, compromised health-related quality of life, and elevated stress levels across both genders. All five dimensions of the EQ-5D were negatively impacted by breakfast skipping. Discussion: The findings highlight the detrimental effects of skipping breakfast on sleep patterns, mental health, and overall quality of life, stressing the importance of regular breakfast consumption for enhancing these health outcomes. The study suggests the need for further research to uncover the mechanisms behind these associations and to devise targeted interventions to mitigate the negative impacts of breakfast skipping.

During its pre-motor stage, Parkinson's disease (PD) presents itself with a multitude of non-motor symptoms with different degrees of specificity and sensitivity. The most important among them are REM sleep behavior disorder (RBD) and olfactory dysfunction. RBD is a parasomnia characterized by the loss of REM sleep muscle atonia and dream-enacting behaviors. Olfactory dysfunction in individuals with prodromal PD is usually described as hyposmia (reduced sense of smell) or anosmia (complete loss of olfactory function). These symptoms can precede the full expression of motor symptoms by decades. A close comprehension of these symptoms and the underlying mechanisms may enable early screening as well as interventions to improve patients' quality of life. Therefore, these symptoms have unmatched potential for identifying PD patients in prodromal stages, not only allowing early diagnosis but potentially opening a window for early, possibly disease-modifying intervention. However, they come with certain challenges. This review addresses some of the key opportunities and pitfalls of both RBD and olfactory dysfunction as early markers of PD. [ABSTRACT FROM AUTHOR]

Background: The literature indicates an increasing interest in the mental health of refugees (R) and asylum seekers (AS) – particularly how it could be affected by previous exposure to trauma and violence – but less has been written about the issues they are forced to face during the post-migration period and how these also can affect mental health. Research shows that the mental health of R/AS is highly influenced by their post-migration conditions and may deteriorate due to post-migration social health-related determinants; in addition, a lack of language skills, discrimination, separation from family, poverty, and other stressors can contribute to social isolation. The difficulty in asking for help in case of psychological distress and, consequently, in accessing care, contributes to the worsening of their clinical condition. Aims: The primary purpose of this study is to identify and provide a review of the clinical tools used to screen migrants (R/AS) at risk of developing psychological distress, identifying post-migration difficulties. Methods: We searched studies in PubMed, Embase, Scopus, Cochrane (Central), and Cinahl (ultimate) with the last search on 14 April 2023, using a combination of keywords and Medical Subject Headings (MeSH). Results: Our systematic search identified 1,878 records. After removing duplicates, we screened 1,238 records by title and abstract, retaining 97 for full text review. Of these, 68 met full eligibility criteria (1995–2023). A total of 30 social scales have been identified, as well as structured or semi-structured questionnaires and interviews. Translated into multiple languages, the tools can be self-administered or administered by trained professionals. PMLD is known for its effectiveness in evaluating the post-migration period and predicting mental health issues. Conclusions: Considering the limited number of studies and, consequently, the limited number of tools found, it can be inferred that not enough attention is given to post-migration in the broader sense.

Background: Here, we (a) examined the trajectories of night‐time sleep duration, bedtime and midpoint of night‐time sleep (MPS) from infancy to adolescence, and (b) explored perinatal risk factors for persistent poor sleep health. Methods: This study used data from 12,962 participants in the Avon Longitudinal Study of Parents and Children (ALSPAC). Parent or self‐reported night‐time sleep duration, bedtime and wake‐up time were collected from questionnaires at 6, 18 and 30 months, and at 3.5, 4–5, 5–6, 6–7, 9, 11 and 15–16 years. Child's sex, birth weight, gestational age, health and temperament, together with mother's family adversity index (FAI), age at birth, prenatal socioeconomic status and postnatal anxiety and depression, were included as risk factors for persistent poor sleep health. Latent class growth analyses were applied first to detect trajectories of night‐time sleep duration, bedtime and MPS, and we then applied logistic regressions for the longitudinal associations between risk factors and persistent poor sleep health domains. Results: We obtained four trajectories for each of the three sleep domains. In particular, we identified a trajectory characterized by persistent shorter sleep, a trajectory of persistent later bedtime and a trajectory of persistent later MPS. Two risk factors were associated with the three poor sleep health domains: higher FAI with increased risk of persistent shorter sleep (OR = 1.20, 95% CI = 1.11–1.30, p <.001), persistent later bedtime (OR = 1.28, 95% CI = 1.19–1.39, p <.001) and persistent later MPS (OR = 1.30, 95% CI = 1.22–1.38, p <.001); and higher maternal socioeconomic status with reduced risk of persistent shorter sleep (OR = 0.99, 95% CI = 0.98–1.00, p =.048), persistent later bedtime (OR = 0.98, 95% CI = 0.97–0.99, p <.001) and persistent later MPS (OR = 0.99, 95% CI = 0.98–0.99, p <.001). Conclusions: We detected trajectories of persistent poor sleep health (i.e. shorter sleep duration, later bedtime and later MPS) from infancy to adolescence, and specific perinatal risk factors linked to persistent poor sleep health domains.

• Sleep and circadian problems are often comorbid with mental disorders. • Sleep and circadian problems are mechanistic contributors to mental disorders. • TranS-C treats sleep and circadian problems across mental disorders via one protocol. • TranS-C is grounded in basic sleep and circadian science and existing EBPTs. • TranS-C includes cognitive-behavioral therapy for insomnia (CBT-I) The transdiagnostic intervention for sleep and circadian dysfunction (TranS-C) was developed to provide one protocol that treats a range of sleep and circadian problems across a range of mental disorders. The focus of TranS-C includes, and goes beyond, categorically defined sleep and circadian disorders to facilitate healthy sleep along empirically derived "sleep health" dimensions. In this State of the Science review, we highlight key advantages of a transdiagnostic approach to sleep and circadian problems, including (a) the potential to better understand and treat comorbidity between various sleep and circadian problems and mental disorders, as well as the potential to better understand and treat the heterogeneous sleep and circadian problems that are present within a specific mental disorder; (b) the opportunity to explore the hypothesis that sleep and circadian problems are an important transdiagnostic mechanism in the multifactorial maintenance of mental disorders; (c) the potential to transfer breakthroughs made across siloed areas of research and practice; (d) its suitability for dissemination into a broad range of settings, particularly lower resource settings; and (e) the opportunity to improve a range of important outcomes. We also explain the theoretical underpinnings of TranS-C, including the two-process model of sleep regulation and the Sleep Health Framework. TranS-C includes cognitive-behavioral therapy for insomnia (CBT-I) and we offer recommendations for when to use CBT-I versus TranS-C. The process for developing TranS-C is discussed along with outcome data, applications to underserved communities, and future directions for research. [ABSTRACT FROM AUTHOR]

PROBLEM IDENTIFICATION: Previous reviews have reported the efficacy of acupuncture in managing cancer-related symptoms. However, there is a lack of comprehensive reviews examining how patients' expectancy regarding acupuncture influences treatment outcomes in the context of cancer survivorship. LITERATURE SEARCH: 9 databases were searched for articles published through August 2023. The authors included acupuncture studies that reported on patient expectancy for the effectiveness of acupuncture. DATA EVALUATION: 10 studies were included in this review. Study quality was assessed using the Cochrane risk-of-bias tool and the ROBINS-I (Risk Of Bias In Non-randomised Studies-of Interventions) tool. SYNTHESIS: 5 studies explored the relationship between expectancy and cancer-related outcomes, and in 3, expectancy was significantly associated with reduced pain, frequency of bowel movements, and severity of insomnia. Male and older patients, nonresponders to acupuncture, and those with lower education levels had lower expectancy regarding acupuncture. IMPLICATIONS FOR NURSING: Healthcare providers should assess patient expectancy to comprehensively understand its role in improving acupuncture outcomes. [ABSTRACT FROM AUTHOR]

OBJECTIVES: To explore the incidence of adverse childhood experiences (ACEs) in breast cancer survivors and potential associations with long-term treatment-related sequelae. SAMPLE & SETTING: English-speaking breast cancer survivors three or more years from diagnosis with complete treatment response (N = 120) were recruited prior to scheduled survivorship clinic visits. METHODS & VARIABLES: Participants in this crosssectional observational feasibility study rated anxiety, depression, fatigue, sleep disturbance, cognitive issues, resilience, and ACEs (experienced prior to age 18 years). Blood samples were analyzed for inflammatory and epigenetic biomarkers. RESULTS: ACEs assessment was feasible. Higher ACE scores correlated with greater fatigue, anxiety, and depression, and with lower cognitive function (p < 0.05). Resilience was positively associated with cognitive function and negatively associated with fatigue, anxiety, and depression. IMPLICATIONS FOR NURSING: There is evidence for the impact of ACEs on long-term treatment-related sequelae in women with breast cancer. Oncology nurses should consider incorporating ACEs assessment into the workflow for women receiving survivorship care. [ABSTRACT FROM AUTHOR]

Although there are many sleep-related complaints in chronic obstructive pulmonary disease (COPD) patients, nocturnal leg cramps have not been adequately and extensively studied. This study fills a significant gap in the literature by determining the prevalence and influencing factors of nocturnal leg cramps in COPD patients. However, our findings also underscore the need for further research, inspiring future studies and interventions in this area. This study was conducted with a rigorous methodology, employing a comprehensive approach to evaluate the probability of experiencing nocturnal leg cramps in 215 COPD and 215 control group patients matched for age and gender. Logistic regression analysis was used, supplemented by artificial neural networks, to identify the influencing factors. This robust methodology ensures the reliability and validity of our findings. The findings of this study are not only significant but also enlightening, shedding light on the prevalence and influencing factors of nocturnal leg cramps in COPD patients. The frequency of experiencing these cramps was found to be 40.9% in chronic obstructive pulmonary patients and 21.9% in the control group (p <.05). In COPD patients, factors such as milk group food consumption, blood erythrocyte level, the cover used while sleeping, blood creatinine level, the presence of coronary artery disease, the diagnosis of diabetes mellitus, the upper mid-arm muscle area, and use of drugs with methylxanthine active ingredient methylxanthine were found to affect the occurrence of these cramps. Our findings not only call for further research but also have immediate practical implications. They highlight the crucial role of nurses in managing nocturnal leg cramps in COPD patients. By controlling patients' cold stress, the bed covers they use, and their dairy product consumption, nurses can significantly contribute to managing these cramps, thereby improving the quality of life for these patients. This underscores the importance of their role in patient care and management. [ABSTRACT FROM AUTHOR]

Background: Temporomandibular joint disorder (TMD), a prevalent orofacial disorder with complex aetiologies and considerable socioeconomic costs. This underscores the critical importance of developing a comprehensive understanding of the risk factors associated with TMD, as existing research is hindered by deficiencies in establishing causal relationships and the limitations of traditional research methodologies. Objectives: This research explores the causal link between certain risk factors and temporomandibular joint disorder (TMD) through Mendelian randomization (MR), providing multidimensional perspectives in addressing this worldwide health issue. Methods: Utilizing instrumental variables, we applied advanced statistical methods, including the weighted median, inverse variance weighted (IVW) and MR‐Egger, to evaluate the impact of twelve potential risk factors on TMD. Results: Our results identified a significant positive association of TMD with malocclusion (p <.001), sleeping disorders (p =.006), anxiety (p =.002), major depression (p =.0002), daily cigarettes consumption (p =.029) and autoimmune diseases (p =.039). Conversely, a negative association was observed with educational attainment (p =.003). Conclusion: These findings suggest that malocclusion, sleeping disorders, anxiety, major depression, daily cigarettes consumption and autoimmune diseases, could potentially increase TMD risk while educational attainment might mitigate its increase. No direct causal relationships were established between serum 25‐hydroxyvitamin D levels, menopause, frequent alcohol consumption, coffee intake and severely worn dentition and TMD.
