Key Components of Trauma-Informed Yoga Nidra.

Trauma exposure is universal to the human condition, with many affected individuals experiencing either posttraumatic stress disorder (PTSD) or subthreshold manifestations. Both scenarios can become functionally debilitating and collectively lay a heavy burden on individuals and society. Yoga nidra is one adjunctive treatment of growing interest, holding potential for its ability to alleviate symptoms of trauma, including hypervigilance, sleep disturbances, and disembodiment. However, yoga nidra practices can have re-traumatizing side-effects if not delivered conscientiously. For instance, adverse reactions such as overwhelming flashbacks, emotional distress, and extended dissociation have been reported as a result of yoga nidra practice. To prevent harm and maximize yoga nidra's therapeutic potential, 10 key components of trauma-informed yoga nidra practice are presented: (1) safe(r) and comfortable environment; (2) personal autonomy, healthy boundaries, and consent; (3) skillful mindful awareness; (4) appropriate length and preparation; (5) adequate settling and externalization; (6) sleep permission; (7) self-chosen intention; (8) flexible rotation of consciousness and breath awareness; (9) embodied pairs of opposites; and (10) conscientious visualizations. These measures protect those living with trauma and have extended benefits for nonclinical populations as well. That said, some of these components may be adapted based on context, especially in settings where direct feedback is readily available and can be prioritized. Ultimately, thoughtful decisions must be made with the intention of optimizing the safety of and benefit to the practitioners under the facilitator's care.

Urinalysis and perceived effects following 2-week use of a commercial broad-spectrum cannabidiol product.

A growing number of hemp-derived cannabidiol (CBD) products are available with negligible amounts (< 100 ppm) of delta-9-tetrahydrocannabinol (THC) due in part to consumer concerns regarding the risk of positive drug screens. There are, however, no published studies that report whether repeated use of these products may lead to positive urine drug tests for THC. There is also scant research on the effects of these products on physical and mental well-being. Twenty healthy adults consumed a hemp-derived broad-spectrum CBD product every day for 2 weeks. Participants attended study visits at the beginning and end of the 2-week period. At each visit, participants underwent urinalysis testing for CBD, THC, and metabolites (analyzed via liquid chromatography with tandem mass spectrometry) and completed a validated assessment of physical and mental well-being. Participants reported using an average of 1.09 ± 0.51 ml (34.20 ± 16.00 mg CBD) of study product per day. Neither tetrahydrocannabinol nor its metabolites were detectable in urine following the 2-week period of use. Ingestion of the broad-spectrum product was associated with a significant reduction in sleep disturbance and pain intensity symptoms (p < .05), which remained significant after correcting for possible confounds (i.e., age, sex, dosage). No adverse events were reported. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

The trajectories and associations of sleep disturbance symptoms with suicidal ideation in adolescents: A three-wave longitudinal study

BackgroundThis study aimed to investigate the developmental trajectories of sleep disturbance symptoms and examine whether specific trajectory memberships of sleep disturbance symptoms could prospectively predict suicidal ideation (SI) among a large sample of Chinese adolescents over one year. MethodsA three-wave longitudinal study was conducted from April 2021 to June 2022, with a sample of 19,095 adolescents from Shenzhen in Guangdong Province, China (51.2 % males; mean age = 12.4 ± 1.6 years at baseline). Socio-demographics (at baseline), SI, sleep disturbance symptoms (at each assessment), depressive symptoms (at the last follow-up), and negative life events (at two follow-ups) were assessed. Data were analyzed employing Growth Mixture Modeling and binary logistic regressions. ResultsThe Growth Mixture Modeling identified four trajectories of sleep disturbance symptoms over one year: resistant group (76.2 %), delayed-dysfunction group (8.8 %), recovery group (7.4 %), and chronic-dysfunction group (7.6 %). Binary logistic regression analysis revealed that adolescents in the group of delayed-dysfunction (OR = 2.86, 95 % CI = 2.51–3.27) and chronic-dysfunction (OR = 2.14, 95 % CI = 1.84–2.47) exhibited higher risks of developing SI compared to those in the resistant group, even after controlling for socio-demographics, negative life events, depressive symptoms, and baseline SI. ConclusionsThese findings underscore the importance of identifying individuals at higher risks of sleep disturbance and providing personalized and effective mental health services to reduce the incidence of SI.

Don’t forget to mind the mind: a prospective cohort study over 12 months on mental health symptoms in active professional male footballers

AimsWe examined the prevalence and incidence of mental health symptoms (MHS) in active professional male footballers over a 12-month period and investigated if MHS was associated with severe injuries or surgeries.Participants and methodsFootball Players Worldwide (FIFPRO) affiliated national unions invited active professional male football players to participate in the study. MHS was operationalised in symptoms of anxiety, disordered eating, depression, distress, sleep disturbance, alcohol misuse and drug misuse, all being assessed with validated questionnaires.ResultsOf the 101 participants enrolled, the prevalence of distress was 53% and MHS was between 6% for drug misuse and 48% for alcohol misuse. The incidence of distress was 29% and MHS ranged from 1% for anxiety to 11% for sleep disturbance. At baseline, players suffering from injury/surgery were more likely to report depression (OR 1.35; 95%CI 1.10–1.70) and disordered eating (OR 1.22; 95%CI 1.02–1.47). At follow-up, players who suffered injury or surgery were inclined to report distress (OR 2.15; 95%CI 1.26–4.31) and drug misuse (OR 2.05; 95%CI 1.01–4.04).ConclusionThere seems to be a greater prevalence of MHS in active professional male footballers than in the global population and other sports. After severe injury/surgery, the risk of developing MHS is increased, confirming that healthcare professionals should be aware of the mental health of injured players.

Psychosocial Determinants for Self-Reported Health Status in Hemodialysis Patients: A Cohort Analysis of the CONVINCE Randomized Trial.

We investigated whether psychosocial determinants self-efficacy and social support are associated with Health-Related Quality of Life in hemodialysis patients enrolled in the CONVINCE trial. We used baseline data from the cohort of patients involved in the CONVINCE randomized trial of hemodiafiltration versus hemodialysis. Measures included age, gender, relationship status, children, housing, education, employment, comorbidities, dialysis schedules, time of first dialysis, residual kidney function, general self-efficacy and social support scores, and PROMIS measurements for health-related quality of life. Associations were analyzed using hierarchical regression. One thousand three hundred and sixty patients from CONVINCE were the cohort of interest. Mean age was 62±13.5 years (range 20-92), and 66.9% were men. Self-efficacy was a significant predictor for all health-related quality of life domains: depression (β = -0.36, p < 0.001), anxiety (β = -0.35, p < 0.001), social participation (β = 0.32, p < 0.001), cognition (β = 0.29, p < 0.001), fatigue (β = -0.29, p < 0.001), physical function (β = 0.27, p < 0.001), sleep disturbance (β = -0.23, p < 0.001), pain interference (β = 0.21, p < 0.001), pain intensity (β = -0.17, p < 0.001), interdialytic symptoms (β = -0.14, p = 0.002) and intradialytic symptoms (β = -0.14, p = 0.002). Social support was a significant predictor for cognition (β = 0.21, p < 0.001), sleep disturbance (β = -0.11, p = 0.017) and intradialytic symptoms (β =- 0.11, p = 0.02). Higher general self-efficacy scale scores are associated with improvements in cognition, depression, anxiety, social participation, fatigue, physical function, sleep disturbance, pain interference, interdialytic symptoms, pain intensity and intradialytic symptoms. Associations for self-efficacy are larger than those for social support and stronger than previously reported. It is plausible that targeted psychosocial interventions may improve health outcomes in people on hemodialysis.

The Impact of Adenotonsillectomy on the Quality of Life of Children with Obstructive Sleep Apnea.

Introduction In children, obstructive sleep apnea (OSA) is a sleep-related breathing disorder that is caused by adenotonsillar hypertrophy and is characterized by upper airway obstruction disturbing sleep. Objective We conducted this study to evaluate health-related quality of life (QoL) in children with OSA before and after adenotonsillectomy. Methods A descriptive, observational study was conducted among 43 children in the 4-to-12 years old age group who had symptoms of OSA due to adenotonsillar hypertrophy and who underwent adenotonsillectomy at a tertiary care center during the period from February 2020 to February 2021. The QoL was assessed using the OSA-18 questionnaire preoperatively and at 2 and 6 months postoperatively. Results Among the study population, males (72)%) were more affected with OSA, with a male-to-female ratio of 2.6:1. Based on the OSA-18 questionnaire assessment, the most severe and frequently observed symptoms were in the domains of sleep disturbance and physical symptoms, in which the mean score was 77 preoperatively. After adenotonsillectomy, the mean OSA-18 score decreased to 28.605 and 22.465 at 2 and 6 months, respectively. At 2 months postsurgery, more significant improvement was noticed in sleep disturbances, physical symptoms, and parent's concern while at 6 months postsurgery, all domains showed equal improvement. Therefore, following adenotonsillectomy, the QoL improved significantly. Conclusion Obstructive sleep apnea can adversely affect sleep quality as well as neurocognitive and cardiovascular functions. Adenotonsillectomy resulted in significant improvement in the QoL.

An Observational Study on the Treatment Outcomes of Adenotonsillar Hypertrophy in Children

Background: Adenotonsillar hypertrophy, marked by abnormal enlargement of the adenoids and tonsils, is common in children and can cause various health issues. For severe cases, surgical intervention, mainly adenotonsillectomy, is often recommended and has proven effective in improving airway obstruction, sleep quality, and overall health outcomes. This study aimed to assess the treatment Outcomes of adenotonsillar hypertrophy in children. Methods: This prospective observational study was conducted in the Department of Head &amp; Neck Surgery (ENT), Dhaka National Medical Institute Hospital, Dhaka, Bangladesh from January 2023 to June 2023. A total of 57 children with primary symptoms of mouth breathing, snoring, and sleep disturbances were purposively enrolled as study subjects. For data analysis, MS Office tools were applied. Results: Most participants (61.4%) were aged 2-5 years and female (60%). All participants (100%) reported symptoms of nasal blockage, snoring, and mouth breathing. A majority (61.4%) had grade 2 tonsillar hypertrophy. After 3 months of medical treatment, 57.9% experienced complete relief of nasal symptoms, including sleep apnea, 24.6% showed moderate improvement, and 17.5% saw no improvement. Conclusion: Intranasal steroids, combined with oral amoxicillin e-clavulanic acid and montelukast, reduce adenotonsillar hypertrophy symptoms and lower surgical intervention rates. This approach targets inflammation and infection, potentially improving patients' quality of life. More studies are needed to establish guidelines and optimize treatment.

Do acute mountain sickness and psychiatric disorders show overlapping symptoms?

The Lake Louise Score (LLS) is a common tool for diagnosing acute mountain sickness (AMS) after a recent gain in altitude. Required symptoms (headache, dizziness, fatigue or gastrointestinal symptoms) are unspecific, subjective and not detectable by physiological parameters. (Talks et al., 2022; Boos et al., 2018) This study aimed to enhance present knowledge concerning the impact of mental health on LLS. In a cross-sectional questionnaire study, we assessed 3 groups: 100 inpatients (Ward for psychosomatic medicine – Innsbruck, PSY), 73 mentally healthy individuals (Innsbruck, Austria at an altitude of 570 m, CO) and 223 mountaineers in Nepal (Pheriche 4,371 m and Dingboche 4,410 m, NEPAL). Beside social demographics and LLS 2018 (cutoff for LLS-positivity: LLS ≥ 3 including at least 1 point for headache), we examined symptoms of anxiety (Zung Self-Rating Anxiety Scale [SAS], General Anxiety Disorder Questionnaire 7 [GAD-7]), affective states (International Positive and Negative Affect Schedule Short form [I-PANAS-SF]) and sleep (Insomnia Severity Index [ISI]). In this preliminary analysis, the average age was 39 ± 16 years in PSY, 34 ± 16 years in CO and 40 ± 14 years in NEPAL. Gender distribution showed greater portion of women in PSY and CO (PSY: 72% female 24% male 3% non-binary, CO: 64% female 36% male) contrary to NEPAL (36% female 64% male). At sea level, 67% scored LLS-positive in PSY and 12% in CO (Fishers exact test, p &lt; 0.001). In NEPAL 25% met AMS-criteria by LLS. CO and NEPAL score significantly lower in LLS than PSY (ANOVA: diff = -3.70, p &lt; 0.0001; diff = -3.68, p &lt; 0.0001, respectively). PSY and CO showed significant weak to moderate correlations (Spearman-Rho, p &lt; 0.001) of anxiety (SAS, GAD), affective states (I-PANAS-SF) and sleep impairment (ISI) with LLS-sum. NEPAL showed significant very-weak to weak correlations of insomnia, anxiety and negative affect with LLS-sum. Using logistic regression analysis (Figure 1), higher odds of LLS-positivity are significantly associated with insomnia and anxiety (ISI, SAS) in PSY, with anxiety in CO (SAS) and insomnia and negative affect in NEPAL. While of course a recent gain in altitude is a prerequisite for the diagnosis of AMS this study shows that patients with pre-existing mental illness at low altitude score more frequently false-positive on the LLS than a mentally healthy cohort. Symptoms of anxiety, negative affect and sleep disturbance can affect the AMS-defining questionnaire of LLS both at sea level and at high altitude. There is still uncertainty on a possible common pathophysiological pathway of psychiatric diseases and AMS since there is no Gold Standard in diagnosing AMS. Concerning (well-)established risk-factors for AMS like speed of ascent (Berger et al., 2023) and female sex (Hou et al., 2019), we see no evident data. The data presented here suggest that strength of expression of negative affect can cause positive LLS scoring. Acute mountain sickness and psychiatric disorders show overlapping symptoms at sea level. At high altitudes, negative affect seems to be a possible cause for the development of AMS. Further research focus should be placed on mountaineers in high altitude with psychiatric disorders and their mental state.

Sleep Disturbances in Autoimmune Neurological Diseases: Mechanisms, Clinical Characteristics, Assessment, and Treatment Strategies.

Sleep disturbances are a hallmark feature of various autoimmune neurological diseases (AINDs). However, limited awareness of these sleep manifestations exists among clinicians. We provide a comprehensive overview of assessment methods, characteristic sleep disturbances, the impact of specific antibodies on sleep patterns, and treatment strategies for sleep disturbances in AINDs. Research advancements in sleep disturbances in autoimmune neurological disease focus primarily on four areas: mechanisms, clinical characteristics, assessment, and treatment. Regarding mechanisms, animal models for AINDs, particularly those involving specific antibodies like anti-NMDAR, anti-LGI1, and anti-IgLON5, have become more comprehensive. Recent advancements in animal models have led to the establishment of numerous models for AINDs; these models include a wide range of antibodies, including anti-NMDAR, anti-LGI1, and anti-IgLON5. Several studies using these models have revealed common mechanisms underlying sleep disturbances in these diseases. In terms of clinical characteristics, the identification of antibodies associated with recently discovered AINDs has expanded the spectrum of sleep disturbance symptoms observed compared to prior findings. A comprehensive evaluation system for the assessment of sleep disturbances has been established, including questionnaires, polysomnography, functional magnetic resonance imaging, and 18F-FDG PET/CT. Additionally, cardiopulmonary coupling shows promise as a novel assessment tool. Currently, no universally effective treatment exists for sleep disturbances in autoimmune neurological diseases, either through symptomatic treatment or immunosuppressive therapy. Further studies are needed to confirm the efficacy of new therapies and validate the benefits of existing treatments. Sleep disturbances are a hallmark feature of AINDs. Recent advancements have significantly expanded our understanding of their assessment and treatment. However, further studies are needed to address the remaining uncertainties in sleep disturbance management.

A systematic review of yoga for the treatment of gastrointestinal disorders.

Several studies have reviewed yoga for the treatment of disorders of gut-brain interaction (DGBI) with most demonstrating a benefit for symptom reduction; however, yoga has been studied beyond DGBI. The aim of this systematic review is to provide a comprehensive summary of yoga as treatment for gastrointestinal conditions. We conducted literature searches in PubMed and Embase and included yoga trials of adults with a diagnosis of a gastrointestinal disorders and diseases. We identified 1275 articles; 12 studies were eligible. Most studies compared yoga to controls, for patients with different GI conditions (irritable bowel syndrome, ulcerative colitis, chronic pancreatitis, and gastrointestinal cancer). The type, method, and duration of yoga used varied. Across IBS studies, most demonstrated that yoga improved IBS symptom severity, mood-related symptoms, and quality of life compared with controls. In one study of inflammatory bowel disease, yoga improved quality of life compared to controls. Two studies of gastrointestinal cancer demonstrated that yoga led to a reduction in sleep disturbance and mood symptoms. One study of chronic pancreatitis found that yoga led to improvements in quality of life, stress, mood changes, alcohol dependence, and appetite. Yoga was generally safe, and no serious adverse events were attributed to the intervention. In conclusion, yoga appears to be safe and has potential to improve functioning across a spectrum of gastrointestinal diseases; however, current studies are limited by heterogeneity and methodological weaknesses. Further research is needed to evaluate the impact of yoga on health outcomes for a broader range of gastrointestinal conditions.

Hair cortisol and psychiatric symptomatology in children; outcomes of group CBT

The associations between hair cortisol concentration (HCC), a biomarker of chronic stress, and behavior and sleep disturbance symptoms have not been studied in children with psychiatric disorders. While cognitive behavioral therapy (CBT) has proven effective in treating psychiatric symptoms in children, its potential biological implications as determined by HCC have not been investigated. We explored associations between HCC, behavior and sleep disturbance symptoms, and different diagnostic groupings (depression/anxiety, ADHD, or other types of psychiatric disorders) in clinician-diagnosed 6-12-year-old children (n = 100) with mixed psychiatric disorders and comorbidities. In addition, we examined whether group CBT led to changes in HCC, behavior symptoms, and sleep disturbance symptoms and whether any fluctuations in HCC levels were associated with potential symptom change. We collected data on HCC, internalizing and externalizing symptoms (The Spence Children's Anxiety Self-Report, Child Behavior Checklist, and Teacher Report Form), and sleep disturbance symptoms (The Sleep Disturbance Scale for Children) at three time points (baseline, post-treatment, and seven-month follow-up). Baseline HCC was not associated with behavior or sleep disturbance symptoms, whereas behavior and sleep disturbance symptoms were mutually correlated. No changes in HCC levels were observed with group CBT. Moreover, potential variations in HCC levels over the course of the study did not appear to be associated with behavior symptom relief after group CBT. Our findings suggest that HCC may not be a methodologically relevant biomarker of behavior or sleep disturbance symptoms in children with diverse psychiatric disorders.

Sleep disturbance as a poor prognostic predictor in patients with advanced non-small-cell lung cancer treated with immune checkpoint inhibitors: A prospective study

BackgroundSleep disturbances are highly prevalent in oncology and often exacerbate symptoms, leading to reduced quality of life, which in turn may further affect the tolerability and efficacy of oncological treatments. Sleep disturbance and cancer have an intimate and complicated relationship, and may be a negative predictor of cancer treatment. The present study aimed to characterize the relationship between sleep disturbance and immune checkpoint inhibitor (ICI) therapy in patients with advanced non-small cell lung cancer (NSCLC). MethodsData from 171 patients with advanced NSCLC, who underwent ICI treatment between December 2020 and October 2022, were analysed in our prospective study. Sleep disturbances were evaluated according to the Pittsburgh Sleep Quality Index (PSQI), with a cut-off value of 5, to investigate the impact of sleep disturbance on the survival of patients with NSCLC and the efficacy of ICI treatment. ResultsThe median progression-free survival (PFS) was10.4 months (9 5% confidence interval [CI]:9.84–10.97). Univariate and multivariate analyses revealed that sleep disturbance and depressive symptom predicted worse prognosis with shortened PFS. Patients who experienced sleep disturbance exhibited a significant reduction in PFS (9.2 vs. 11.8 months; HR: 1.83 [9 5% CI 1.27–2.6 5]; p = 0.001), as did those with depressive states (HR 1.5 5 [9 5% CI 1.06–2.28]; p = 0.02 5). Additionally, patients with sleep disturbance and depressive symptoms exhibited significantly lower objective response rates and disease control rates. ConclusionSleep disturbance could be a factor for prognosis in patients with advanced NSCLC undergoing first- or second-line treatment with ICIs, including shorter PFS and reduced efficacy.

Sleep disturbance, suicidal ideation and psychosis-risk symptoms in individuals at clinical high risk for psychosis

Insomnia and suicidal ideation (SI) are common in schizophrenia, including in individuals at clinical high-risk for psychosis (CHR-P). Previous studies have found associations between sleep disturbance, SI, and psychopathology in schizophrenia. We explored these associations in a CHR-P cohort. We leveraged data from CHR-P individuals in the North American Prodrome Longitudinal Studies (NAPLS-3) (n = 688) cohort. We investigated relationships between sleep disturbance (Scale of Prodromal Symptoms [SOPS]; Calgary Depression Scale for Schizophrenia [CDSS], and the Pittsburgh Sleep Quality Index [PSQI]), suicidal ideation (CDSS), and psychosis-risk symptoms. The prevalence of terminal insomnia, sleep disturbance, and SI in NAPLS3 was 25 %, 69 %, and 29 %, respectively. After controlling for potential confounders, multiple indices of sleep disturbance (SOPS, PSQI: OR = 1.05–1.40) were significant indicators of concurrent SI. Terminal insomnia was not associated with conversion to psychosis. Multiple indices of sleep problems were associated with higher total and subscale psychosis-risk symptom scores (β = 0.09–0.39). Sleep problems are prevalent and associated with SI and more severe psychosis-risk symptoms in CHR-P individuals. These findings underscore the importance of designing longitudinal intervention studies to investigate whether the treatment of sleep disturbances may reduce suicidality and symptoms in this population.

Self-reported sleep duration and quality and cardiovascular diseases among middle-aged and older Chinese: A 7-year longitudinal cohort study.

Cardiovascular disease (CVD) is a leading cause of death worldwide, and several studies have attempted to identify its risk factors. This study aimed to investigate the association between sleep duration and sleep quality, and the 7-year incidence of CVD among middle-aged and older Chinese individuals. A total of 6682 participants aged 45-90 years from the China Health and Retirement Longitudinal Study database were included in this study. The authors estimated sleep duration and quality based on self-reported data of night sleep hours and disturbance symptoms, and examined the associations between them and the composite outcome of CVD using logistic regression models. A total of 1692 participants (25.32%) reported new CVD events during follow-up. Short sleep duration (<6h/night) was significantly associated with a higher risk of CVD in all three models (p<.05). However, this was not observed for long sleep duration (>8h/night). Additionally, participants with mild sleep disturbance in all three models, and severe sleep disturbance in Models 2 and 3 had a significantly higher risk of CVD (p<.05). After stratification by age and daytime napping, we still found a significant association between short sleep duration and CVD in individuals aged 45-59 years, and between sleep disturbance and CVD in non-nappers (p<.05). However, these associations were not significant in individuals aged ≥60 years or in nappers (p>.05). In conclusion, short sleep duration and sleep disturbance are both associated with an increased risk of CVD in middle-aged and older Chinese individuals.

Association between adherence to life’s simple 7 metrics and risk of obstructive sleep apnea among adults in the United States

BackgroundWe aimed to explore the impact of adherence to Life’s Simple 7 (LS7) metrics on risk of obstructive sleep apnea (OSA), and the impact of inflammation on the association, in adults in the United States.MethodsData from 13,825 community-dwelling adults aged ≥ 20 years recruited in the National Health and Nutrition Examination Surveys (NHANES) 2005–2008, 2015–2018 was analyzed. The LS7 score was calculated based on the AHA definition of LS7 metrics. The diagnosis of OSA was based on self-reported symptoms of sleep disturbance using a standard questionnaire. The Multivariable Apnea Prediction (MAP) Index score was also calculated to assess the risk of OSA. Log-binominal regression and negative binomial regression were performed to estimate the associations between LS7 and OSA and MAP index, with odds ratios (ORs) and prevalence ratios (PRs) and their 95% confidence intervals (CIs) calculated. Mediation analysis was performed to estimate the mediating effects of inflammatory indicators on the associations.ResultsA total of 4473 participants (32.4%) had OSA, and the mean MAP index was 0.39. In fully adjusted log-binominal regression models, with total score < 6 as the reference, the ORs (95% CIs) for risk of OSA were 0.90 (0.73, 1.10), 0.76 (0.65, 0.89), 0.78 (0.64, 0.95), and 0.45 (0.38, 0.54) for total score = 6, total score = 7, total score = 8, and total score > 8, respectively (P for trend < 0.001). When LS7 score was analyzed as a continuous variable, each 1-point increase in LS7 score was associated with a 15% decrease in OSA risk (P < 0.001). In negative binominal regression models, the adjusted PRs (95% CIs) for the MAP index were 0.93 (0.90, 0.97), 0.87 (0.84, 0.91), 0.80 (0.77, 0.84), and 0.55 (0.53, 0.57) for total score = 6, total score = 7, total score = 8, and total score > 8, respectively (P for trend < 0.001). For each 1-point increase in LS7 score, the risk of OSA decreased by 13% (P < 0.001). Consistent results were observed in subgroup analysis. Mediation analysis indicated that inflammatory factors, including blood cell count, neutrophil count, and C-reactive protein, positively mediated the association of LS7 with OSA, with a mediation proportion of 0.022 (P = 0.04), 0.02 (P = 0.04), and 0.02 (P = 0.02), respectively.ConclusionsIn a nationally representative sample of US adults, adherence to LS7 metrics was independently associated with reduced OSA risk. Inflammation plays a mediating role in the association between LS7 and OSA.

A latent profile analysis of shift work tolerance among Chinese male sailors during a prolonged non-24-h rotating shift schedule at sea

ABSTRACT Shift work tolerance (SWT) refers to the ability to adapt to shift work without significant adverse consequences. The present study aimed to examine the individual differences in SWT and their predictors and outcomes. Latent profile analyses were conducted using cross-sectional data collected form 448 Chinese male sailors who experienced a prolonged (>30 d) non-24-h rotating shift schedule at sea. Depression, anxiety, sleep disturbance, fatigue, domestic disruption, job satisfaction, work engagement, digestive and cardiovascular symptoms were included as indicators of SWT. The results showed that there existed 2 latent profiles of SWT named as High SWT group and Low SWT group. High SWT group was characterized by low levels on all negative bio-psycho-social outcomes but high levels of work engagement and job satisfaction, while Low SWT group exhibited completely opposite characteristics compared to High SWT group. The level of hardiness could predict profile membership that those with higher level of hardiness were more likely to belong to High SWT group. However, there were no significant differences observed in job performance between two groups. In conclusion, hardiness can serve as a predictor of personnel selection for shift work and hardiness-based intervention programs should be encouraged among the shift workers.

Sleep Disturbance Mediates the Associations Between HIV Stigma and Mental and Physical Health Among Black Adults with HIV.

Black Americans have been disproportionally affected by the HIV epidemic, and experience significant disparities in sleep health, mental health, and physical health domains. Using longitudinal data from a sample of Black adults with HIV, the current study examined the associations between stigma and mental and physical health outcomes and how sleep disturbance may play a mediating role. Data were drawn from a recent randomized controlled trial. Questionnaires were used to examine internalized and anticipated HIV stigma, perceived discrimination (enacted stigma) based on multiple social identities (i.e., HIV-serostatus, race, sexual orientation), sleep disturbance, mental health problems (depressive and posttraumatic stress disorder [PTSD] symptoms), and mental and physical health-related quality of life (HRQOL) at baseline, 7-month follow-up, and 13-month follow-up assessments. Linear mixed modeling was used to examine main effects of stigma on health outcomes; causal mediation analysis was used to estimate indirect paths through sleep disturbance. Internalized and anticipated HIV stigma and multiple discrimination were associated with more sleep disturbance, more depressive and PTSD symptoms, and poorer mental and physical HRQOL. Results also indicated significant indirect paths (i.e., mediation) through greater sleep disturbance between HIV-related stigma and discrimination and mental health and health-related quality of life. Results support that sleep disturbance is a mediating pathway through which different forms of stigmas impact health outcomes. Sleep may be an intervention target to help improve mental and physical well-being and reduce health disparities among racial and ethnic minority people with HIV.

The effect of expiratory flow limitation on supine persistent hyperinflation in COPD: a prospective observational study.

COPD is characterised by airflow obstruction, expiratory airway collapse and closure causing expiratory flow limitation (EFL) and hyperinflation. Supine posture may worsen ventilatory function in COPD, which may cause hyperinflation to persist and contribute to symptoms of orthopnoea and sleep disturbance. Our aim was to determine the impact of supine posture on hyperinflation, dynamic elastance and EFL in COPD and healthy subjects. We hypothesised that changes in hyperinflation in supine posture are influenced by EFL and gas trapping in COPD. Clinically stable COPD patients (compatible symptoms, smoking >10 pack-years, obstructed spirometry) and healthy controls underwent oscillometry in the seated and supine positions. Hyperinflation was measured by inspiratory capacity (IC) and the ratio of IC to total lung capacity (IC/TLC) while seated and supine EFL was measured as the difference in mean inspiratory and mean expiratory oscillatory reactance at 5 Hz (X rs5). Relationships between IC, IC/TLC and X rs5, were examined by Spearman correlation. 42 COPD patients demonstrated no change in IC/TLC from seated (0.31 L) to supine (0.32 L) position (p=0.079) compared to significant increases seen in 14 control subjects (0.37 L seated versus 0.44 L supine; p<0.001). In COPD, worse dynamic elastance (X rs5 rs 0.499; p=0.001) and EFL (ΔX rs5 rs -0.413; p=0.007), along with increased age and lower body-mass-index were predictors of supine hyperinflation. Supine persistent hyperinflation occurs in COPD and is associated with increased dynamic elastance and EFL, likely the result of increased airway closure due to gravitational redistribution of lung mass.

The bidirectional relationship between sleep disturbance and anxiety: Sleep disturbance is a stronger predictor of anxiety

BackgroundBoth sleep disturbance and anxiety are common problems that significantly affect human health, but little is known about their causal relationship. The aim of this study was to explore the causal relationship between them with a large sample of community-dwelling adults included. MethodsData for this study were extracted from the baseline survey of West China Natural Population Cohort Study (WCNPCS) and follow-up in the following year. The sleep quality was assessed using Pittsburgh Sleep Quality Index (PSQI), and anxiety was screened using the Generalized Anxiety Disorder Scale (GAD-7). Age, gender, educational level, marital status, smoking status, drinking status, depressive symptoms, loneliness and chronic diseases were taken as covariant factors. Logistic regression and cross-lagged models were used for data analyses. ResultsA total of 16699 participants (67.5 % females) were enrolled, with the average age of participants being 57.3 ± 12.7 years. A total of 40.50 % of participants experienced poor sleep quality at baseline and 40.52 % at follow-up. The prevalence of anxiety was 7.58 % at baseline and 4.62 % at follow-up. The results showed that the risk of developing anxiety in individuals with sleep disturbance at baseline was 1.89 times higher than those without (95%CI = 1.43–2.48). Similarly, anxiety increased the risk of developing sleep disturbance by 1.20-fold (95%CI = 1.03–1.39). These results were further supported by the cross-lagged panel models. ConclusionSleep disturbance and anxiety are mutually causal, and the effect of poor sleep on anxiety seems to be more significant. Timely interventions targeting sleep may help to break the vicious circle between sleep disturbance and anxiety symptoms, and improve the quality of life.
