Prevalence of Sleep Disturbance Potential-Associated Factors among Undergraduate Pharmacy Students in Saudi Arabia.

Background: Many studies across the globe have observed the significant effect of sleep disturbance on the academic achievement of medical students. Objective: This research was conducted to define the prevalence of sleep disturbance and to discover the consequences and management of this condition among undergraduate pharmacy students of Mohammed Al-Mana College for Medical Sciences (MACHS). Methods: We conducted a questionnaire-based online survey among different levels of MACHS pharmacy students. Results: A total of 165 students participated in the study, of whom 132 (80%) were females and 33 (20%) were males. Most of the participants, 142 (86.06%), were staying with their parents, whereas few of them were staying alone (23; 13.94%). While a handful of them, 29 (17.58%), did not have their bedrooms, most of them had their bedrooms (136; 82.42%). When asked about drinking caffeine-rich products in the afternoon or at night, most of them responded "sometimes" (78; 47.27%), followed by the category "always" (61; 36.97%), "rarely" (15; 9.09%), and then the category of students who responded "not at all" (11; 6.67%). Overall, 35 (21.21%) of the study participants had a smoking habit, 72 (43.63%) tried to treat their sleep disturbance, whereas 42 (25.45%) were getting treatment for insomnia. Conclusion: Most pharmacy students at MACH College, especially females, have sleep problems. Mostly, the prevalence is common during exam periods, and it mildly affects their grade point average.

Potential vicious cycle between postoperative pain and sleep disorders: A bibliometric analysis.

Background: Surgical pain affects postoperative sleep quality, and they jointly form a vicious cycle of mutual influence. The cycle of postoperative pain and sleep disorders could lead to delirium, cardiovascular disease, and hyperalgesia, which significantly affect patients' postoperative recovery. Thus, exploring this phenomenon is of great importance for surgical patients, and warrants further investigation. Objective: By employing bibliometric methods, this study systematically analyzes the publications on postoperative pain-sleep disorders, identifies research trends and field dynamics, and ultimately provides insights for further progress in this research area. Methods: In this study, we searched the Web of Science database for studies on postoperative pain and sleep disorders from 2013 to 2023, and analyzed the number of publications, journals, authors, institutions, country regions, and keywords by utilizing CiteSpace, VOSviewer, and Bibliometrix. Results: The 1894 retrieved publications showed a trend of increasing number of publications and correlations between postoperative pain and sleep disorders from 2013 to 2023. The top countries for publications included the USA, China, etc., establishing a global collaborative network centered around the USA, China, and Europe. The top institutions for publications included University of California System, Harvard University, etc. The top authors include Christine Miaskowski, Steven M. Paul, Qiuling Shi, etc. These publications involved multiple disciplines including surgery, neurology, and anesthesiology, and various research funds including NIH, HHS, NSFC, etc. The top journals for publications included the European Archives of Oto-Rhino-Laryngology, etc. Keywords that appear most frequently in this field include "pain", "surgery", "quality of life", "sleep", "depression", and "outcomes". The thematic map indicated that the hot topics in this area include obstructive sleep apnea, tonsillectomy, children, pain, quality of life, and sleep. The undeveloped topics with research potential included postoperative pain, analgesia and dexmedetomidine, breast cancer, fatigue, and lung cancer. Conclusion: The increased number of publications and correlations between postoperative pain and sleep disorders, and the collaborative network across the USA, China, and Europe indicate a growing global interest in this area. This study also provides valuable insights into the trend of hot topics and frontiers and shows that this is an evolving and dynamic research area.

The Role of Family Physicians in Children's Sleep.

Sleep holds significant importance for maintaining health and aiding in illness recovery. Its deprivation impacts all human organ systems, from cognitive function, social interaction, and work capacity to cellular regeneration and immune function. Therefore, sleep plays a crucial role in our body and maintaining health and well-being. Given its importance and close relationship with the neurodevelopment and growth of children and adolescents, this topic is highly significant in pediatric and adolescent health consultations. Family physicians, due to their proximity and understanding of the individual within their family, have the prerogative to contribute to family literacy, empower them, and significantly enhance the quality of life and overall health.

Readjustment of circadian clocks by exercise intervention is a potential therapeutic target for sleep disorders: a narrative review.

PURPOSE: Circadian clocks are evolved endogenous biological systems that communicate with environmental cues to optimize physiological processes, such as the sleep-wake cycle, which is nearly related to quality of life. Sleep disorders can be treated using pharmacological strategies targeting melatonin, orexin, or core clock genes. Exercise has been widely explored as a behavioral treatment because it challenges homeostasis in the human body and affects the regulation of core clock genes. Exercise intervention at the appropriate time of the day can induce a phase shift in internal clocks. Although exercise is a strong external time cue for resetting the circadian clock, exercise therapy for sleep disorders remains poorly understood. METHODS: This review focused on exercise as a potential treatment for sleep disorders by tuning the internal circadian clock. We used scientific paper depositories, including Google Scholar, PubMed, and the Cochrane Library, to identify previous studies that investigated the effects of exercise on circadian clocks and sleep disorders. RESULTS: The exercise-induced adjustment of the circadian clock phase depended on exercise timing and individual chronotypes. Adjustment of circadian clocks through scheduled morning exercises can be appropriately prescribed for individuals with delayed sleep phase disorders. Individuals with advanced sleep phase disorders can synchronize their internal clocks with their living environment by performing evening exercises. Exercise-induced physiological responses are affected by age, sex, and current fitness conditions. CONCLUSION: Personalized approaches are necessary when implementing exercise interventions for sleep disorders.

Effects of high-intensity interval training on sleep disturbances associated with posttraumatic stress disorder.

Sleep disturbances are common in individuals with posttraumatic stress disorder. Exercise interventions are a promising approach in the treatment of sleep disorders, but little is known about the efficacy of exercise interventions for sleep disturbances associated with posttraumatic stress disorder. A total of 40 individuals with posttraumatic stress disorder were randomized to six sessions of either high-intensity interval training or low-to-moderate-intensity training, administered within 12 days. Sleep quality was assessed over 24 days from baseline to post with the Pittsburgh Sleep Quality Index, a sleep log, and a waist-worn actigraphy. Analyses revealed that, regardless of group allocation, Pittsburgh Sleep Quality Index score improved significantly by 2.28 points for high-intensity interval training and 1.70 points for low-to-moderate-intensity training (d = 0.56 for high-intensity interval training; 0.49 for low-to-moderate-intensity training) over time, while there were no significant changes in any sleep log or actigraphy measure. Analysis of a subsample of those affected by clinically significant sleep disturbances (n = 24) revealed a significant time effect with no difference between exercise interventions: Pittsburgh Sleep Quality Index improved significantly by 2.65 points for high-intensity interval training and 2.89 points for low-to-moderate-intensity training (d = 0.53 for high-intensity interval training; 0.88 for low-to-moderate-intensity training), and actigraphy measure of wake after sleep onset was reduced significantly by 14.39 minutes for high-intensity interval training and 6.96 minutes for low-to-moderate-intensity training (d = 0.47 for high-intensity interval training; 0.11 for low-to-moderate-intensity training) from baseline to post. In our pilot study, we found an improvement in sleep quality from pre- to post-assessment. There were no significant differences between exercise groups. Further studies are needed to investigate whether the found time effects reflect the exercise intervention or unrelated factors.

Effects of High-altitude Hypoxia on Drug Metabolism and Pharmacokinetics of Sedative-hypnotic Drugs and Regulatory Mechanism.

Sedative hypnotics effectively improve sleep quality under high-altitude hypoxia by reducing central nervous system excitability. High-altitude hypoxia causes sleep disorders and modifies the metabolism and mechanisms of drug action, impacting medication therapy's effectiveness. This review aims to provide a theoretical basis for the treatment of central nervous system diseases in high-altitude areas by summarizing the progress and mechanism of sedative-hypnotics in hypoxic environments, as well as the impact of highaltitude hypoxia on sleep.

Sex Differences in Mental Health Symptoms in Elite Athletes: A Systematic Review and Meta-analysis.

CONTEXT: Mental health is a growing area of concern for elite athletes. OBJECTIVE: To determine the sex differences in mental health symptoms in elite athletes. DATA SOURCES: PubMed, EMBASE, and Cochrane Library databases were used. STUDY SELECTION: Included studies included comparisons of mental health symptoms of athletes by sex. STUDY DESIGN: Systematic review and meta-analysis were conducted following the PRISMA guidelines. LEVEL OF EVIDENCE: Level 2a. DATA EXTRACTION: The rate ratio (RR) was calculated as the rates in female and male athletes. Data were pooled using a random-effects model. RESULTS: Of 1945 articles identified, 60 articles were included. Male athletes reported higher alcohol misuse (RR, 0.74; CI, 0.68-0.80), illicit drug abuse (RR, 0.82; CI, 0.75-0.89), and gambling problems (RR, 0.14; CI, 0.08-0.25). Female athletes reported higher overall anxiety (RR, 1.17; CI, 1.08-1.27), depression (RR, 1.42; CI, 1.31-1.54), distress (RR, 1.98; CI, 1.40-2.81), and disordered eating (RR, 2.19; CI, 1.58-3.02). Sleep disturbances were reported at similar rates in male and female athletes (RR, 1.13; CI, 0.98-1.30). CONCLUSION: Female and male athletes have significant differences in reported mental health symptoms. Female athletes are more likely to report anxiety, depression, distress, and disordered eating, while male athletes report more alcohol misuse, illicit drug abuse, and gambling. Monitoring and evaluation of mental health is a necessary part of any sport, including access to resources. Longitudinal studies following athletes over time to determine the development and causation for mental health symptoms should be included in future research directions.

German translation, cultural adaptation for Austria and validation of the Neurological Sleep Index - Multiple Sclerosis (NSI-MS).

STUDY OBJECTIVES: To translate, culturally adapt, and validate the Neurological Sleep Index - Multiple Sclerosis (NSI-MS) for use in Austrian German-speaking populations with multiple sclerosis (pwMS). METHODS: Following established guidelines, the NSI-MS diurnal sleepiness (DS), non-restorative nocturnal sleep (NRNS), and fragmented nocturnal sleep (FNS) scales underwent forward-backward translation, with content and face validity, and cultural adaptation to Austria established. Construct validity was evaluated using Rasch analysis. Known-groups validity was examined, and comparisons were made with scales measuring MS fatigue, daytime sleepiness, sleep quality, anxiety, and depression. Reliability was assessed through Cronbach's alpha, Person Separation Index, Lin's concordance correlation coefficient, measurement error, and floor and ceiling effects. Data were merged with a historic English dataset for comparison between English/German language versions. RESULTS: The translation and cultural adaptation of the NSI-MS-G were successful. Pretesting involved 30 pwMS, while the validation included 400 pwMS with mild-to-severe disability. The DS, NRNS, and FNS scales exhibited good fit parameters, were unidimensional, and invariant. NSI-MS-G scales demonstrated excellent convergent and known-groups validity, internal consistency, person separation reliability, test-retest reliability, adequate measurement error, and low floor and ceiling effects. Pooling English and German datasets revealed that person estimates for the NRNS and FNS scales are equivalent across versions, unlike the DS scale. CONCLUSIONS: The NSI-MS-G demonstrates validity, reliability, and responsiveness in assessing DS, NRNS, and FNS in pwMS, generating interval-level data, and shows equivalence between its English and German versions.

Clinical Manifestations' Spectrum of Smartphone Addiction: Moving from an Addiction toward a Clinical Syndrome.

Background: Smartphone addiction is an emerging type of addiction in the digital era, characterized by smartphone dependence that negatively affects human health with a wide range of psychological and physical manifestations. Objective: This study aimed to evaluate the detailed clinical manifestations of smartphone addiction as a delineated clinical syndrome. Methods: A cross-sectional study design was employed to assess smartphone addiction prevalence and its health impacts among Syrian undergraduates using the Smartphone Addiction Scale-Short Version (SAS-SV 2013), the Kessler psychological distress scale (K-6), and a comprehensive assessment of the clinical manifestations frequently linked to smartphone addiction in the literature. Different statistical modeling techniques were applied; a P value of < .05 was considered statistically significant. Results: Of 1532 invited undergraduates, 1401 (91.45%) completed the assessment adequately. Most participants were females (59.7%) and below 23 years of age (73.2%). The prevalence of smartphone addiction was 67.80%; statistically significant smartphone addiction associations were revealed with psychological distress (P < .0001) with odds ratios of 3.308. Most screened physical manifestations also showed a significant association with smartphone addiction. Conclusion: A high prevalence of smartphone addiction was observed with a broad spectrum of associated mental and physical manifestations. As smart device addiction becomes a global health concern, combining the clinical findings reported in the related literature into one clinical identity is necessary to develop a holistic management approach for the delineated clinical syndrome.

α-Synuclein in speculative neuronal extracellular vesicles: A marker for Parkinson's disease risk?

This opinion piece describes major limitations of using α-synuclein in speculative neuronally enriched for diagnosing or predicting Parkinson's disease risk from prodromal conditions such as REM behaviour disorder. It concludes that such an approach is unreliable and recommends that future researchers divert away to more widely accepted approaches such as seed amplification assays.

Direct to psychology for sleep disorders: Innovating models of care in the hospital and health service.

A 'Direct to Psychology Insomnia' pathway was developed for implementation within a multidisciplinary sleep disorders service in a tertiary hospital in Brisbane, Australia. The project was informed by implementation science principles and methodology to re-design the model of care (MoC). A consensus group workshop using the Nominal Group Technique (NGT) with 12 multidisciplinary staff was undertaken to develop the new MoC. The workshop explored inclusion and exclusion criteria for a Direct to Psychology pathway including patient flow and enablers. The team endorsed a MoC that was acceptable to stakeholders and addressed service-level imperatives. The findings highlighted that patient inclusion or exclusion should be overseen by the Sleep Physician team and an Advanced Psychologist with behavioural sleep medicine expertise. Continuum of care for patients referred via primary care providers was considered. Barriers and risks to the MoC changes were identified which informed the refinement of the MoC.

The Psychopathological Predictors and Effects of Death Anxiety.

Death anxiety has been linked to several psychopathological conditions. However, the causes, comorbidity, and differential diagnosis of death anxiety is unexplored. This paper stands out by identifying common predictors of death anxiety and exploring the potential of death anxiety as a predictor for other psychological conditions. The paper reports the findings of four consecutive studies that involved a total of 2291 conveniently selected participants including 861 men and 1430 women. We focused on clarifying both the predictors of death anxiety and the psychopathological consequences emerging from it. Our findings established depression, anxiety, stress, fear of aging, and reduced life satisfaction as predictors of death anxiety. Psychosocial illness, sleep disturbances, aggression, and daily hassles were established as the adverse outcomes of death anxiety. Fear of aging was the most significant predictor of death anxiety and daily hassles emerged as the most significant adverse consequence of death anxiety.

A randomized controlled trial of acupuncture and receptive music therapy for sleep disorders in the elderly-ELAMUS: study protocol.

BACKGROUND: Globally, the demographic shift towards an aging population leads to significant challenges in healthcare systems, specifically due to an increasing incidence of multimorbidity resulting in polypharmacy among the elderly. Simultaneously, sleep disorders are a common complaint for elderly people. A treatment with pharmacological therapies often leads to side effects causing a high potential for dependency. Within this context, there is a high need to explore non-pharmacological therapeutic approaches. The purpose of this study is to evaluate the effectiveness of acupuncture and music therapy, both individually and combined as a multimodal therapy, in the treatment of sleep disorders in individuals aged 70 years and older. METHODS: We conduct a confirmatory randomized controlled trial using a two-factorial study design. A total of n = 100 elderly people receive evidence-based standard care information for age-related sleep disorders. Beyond that, patients are randomly assigned into four groups of n = 25 each to receive acupuncture, receptive music therapy with a monochord, multimodal therapy with both acupuncture and music therapy, or no further therapy. The study's primary outcome measurement is the improvement in sleep quality as assessed by the Pittsburgh Sleep Quality Index (PSQI) (global score), at the end of intervention. Additionally, depression scores (Geriatric Depression Scale), health-related quality of life (Short-Form-Health Survey-12), neurovegetative activity measured via heart rate variability, and safety data are collected as secondary outcomes. Using a mixed-methods approach, a qualitative process evaluation will be conducted to complement the quantitative data. DISCUSSION: The study is ongoing and the last patient in is expected to be enrolled in April 2024. The results can provide valuable insights into the effectiveness of non-pharmacological interventions for sleep disorders among the elderly, contributing to a more personalized and holistic approach in geriatric healthcare.

Effectiveness of Enriched Milk with Ashwagandha Extract and Tryptophan for Improving Subjective Sleep Quality in Adults with Sleep Problems: A Randomized Double-Blind Controlled Trial.

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

Prevalence of dry eye in people over 50 years old in Beichen district, Tianjin city: a cross-sectional population-based survey.

BACKGROUND: A cross-sectional population-based survey in the Beichen district of Tianjin was conducted to estimate the prevalence of dry eye disease (DED) among the population over 50 years old with Dry Eye Workshop (DEWS) II and Chinese expert consensus (CEC) criteria. METHODS: A total of 5791 subjects over 50 years old were enrolled. Ocular surface disease index (OSDI) questionnaire, lipid layer thickness (LLT), partial blink ratio (PBR), fluorescein tear film breakup time (FBUT), Schirmer I test (SIT), fluorescein staining, meibomian gland dropout, meibomian gland expression scores (MES) and quantity scores (MQS) was assessed. Additionally, basic information, weight, disease history, living habits, anxiety, and depression condition were collected. RESULTS: According to the CEC, the prevalence of DED was 39.0%, whereas 44.0% based on DEWS II. The prevalence of DED increased with age and was substantially greater among women (41.1%, 95% CI, 39.5-42.6%) than males (35.1%, 95% CI, 33.1 -37.2%) (p < 0.001). Furthermore, the severity of DED was more severe in women (p = 0.006). The associated risk factors were age, female, depression, smoking, insomnia, and glaucoma. On the other hand, 53.6% of these populations were diagnosed as asymptomatic DED, and the morbidity was higher in males (p = 0.007). CONCLUSIONS: The prevalence of DED in China was relatively high, which was associated with aging, female(sex), depression, smoking and sleep problems. Hence, it is crucial for clinicians and caregivers to be aware of the existence of asymptomatic DED within the susceptible population.

Cognitive behavioral therapy for insomnia in people with chronic musculoskeletal pain. A systematic review and dose-response meta-analysis.

The aims were (i) to determine the effects of Cognitive behavioral therapy for insomnia (CBT-I) on sleep disturbances, pain intensity and disability in patients with chronic musculoskeletal pain (CMP), and (ii) to determine the dose-response association between CBT-I dose (total minutes) and improvements in sleep disorders, pain intensity and disability in patients with CMP. A comprehensive search was conducted in PubMed/MEDLINE, Web of Science, CINAHL, and SCOPUS until December 17, 2023. Randomized clinical trials (RCTs) using CBT-I without co-interventions in people with CMP and sleep disorders were eligible. Two reviewers independently extracted data and assessed risk of bias and certainty of the evidence. A random effects meta-analysis was applied to determine the effects on the variables of interest. The dose-response association was assessed using a restricted cubic spline model. Eleven RCTs (n = 1801 participants) were included. We found a significant effect in favor of CBT-I for insomnia (SMD: -1.34; 95%CI: -2.12 to -0.56), with a peak effect size at 450 min of CBT-I (-1.65, 95%CI: -1.89 to -1.40). A non-significant effect was found for pain intensity. A meta-analysis of disability was not possible due to the lack of data. This review found benefits of CBT-I for insomnia compared to control interventions, with a large effect size. In addition, it was estimated that a 250-min dose of CBT-I had a large effect on reducing insomnia and that the peak effect was reached at 450 min. These novel findings may guide clinicians in optimizing the use of CBT-I in people with CMP and insomnia.

Evaluation of Sleep Quality Among People Living With Type 2 Diabetes Mellitus in Taif, Saudi Arabia: A Cross-Sectional Study.

BACKGROUND:  Type 2 diabetes mellitus (T2DM) is characterized by high blood glucose levels, which are highly associated with poor sleep quality, cardiovascular disease, and pathological changes. This research examines the relationship between sleep quality and T2DM and compares it with nondiabetics within the Taif community. The findings of this study will provide valuable insights and recommendations to enhance the overall health quality in Taif, Saudi Arabia. METHODOLOGY:  A cross-sectional study was conducted on 547 patients with T2DM between December 1, 2023, and April 1, 2024, in Taif. The sleep quality was assessed using the Sleep Quality Questionnaire (SQQ). Data were collected using an online questionnaire with two parts: primary demographic data and an assessment of sleep quality using the SQQ. RESULTS:  Our study enrolled 814 participants, including 547 with T2DM and 267 nondiabetics. Participants with T2DM had poorer sleep quality, with a median score of 21 vs. 25 (P < 0.001). Significant factors affecting sleep quality included gender (P = 0.002), marital status (P = 0.023), and job status (P = 0.023). Nondiabetics had better sleep quality (76%) than participants with T2DM (61.1%). Males, married, and employed individuals reported higher sleep quality scores. CONCLUSIONS:  Research indicates that individuals with T2DM experience lower sleep quality than the general population, particularly among female, unmarried, and unemployed individuals. To enhance sleep quality in patients with T2DM, it is essential to increase awareness, provide education on proper sleep habits, and highlight the importance of effective diabetes management, screening for sleep disorders, and consistent monitoring.

The Triad of Sleep, Immunity, and Cancer: A Mediating Perspective.

The triadic interplay between sleep, immunity, and cancer represents a growing area of biomedical research with significant clinical implications. This review synthesizes the current knowledge on how sleep influences immune function, the immune system's role in cancer dynamics, and the direct connections between sleep patterns and cancer risk. After a comprehensive overview of the interrelationships among these three domains, the mechanisms of sleep in immune function are described, detailing how sleep regulates the immune system, the effects of sleep duration and quality on immune responses, and the underlying molecular and cellular mechanisms. Also, the complex relationship between immunity and cancer is explored, highlighting the immune system's role in cancer prevention and progression, immune surveillance, tumor microenvironment, and the implications of immunodeficiency and immune modulation on cancer risk. The direct connections between sleep and cancer are then described, presenting epidemiological evidence linking sleep patterns to cancer risk, biological mechanisms that influence cancer development, and the role of sleep disorders in cancer prognosis. The mediating role of sleep between immunity and cancer is highlighted, proposing hypothesized pathways, summarizing evidence from experimental and clinical studies, and evaluating the impact of sleep interventions on immune function and cancer outcomes. This review concludes by discussing the clinical implications and future directions, emphasizing the potential for sleep-based interventions in cancer prevention and treatment, the integration of sleep management in oncology and immunotherapy, and outlining a future research agenda. This agenda includes understanding the mechanisms of the sleep-immunity-cancer interplay, conducting epidemiological studies on sleep and cancer risk, assessing the impact of sleep management in cancer treatment protocols, exploring sleep and tumor microenvironment interactions, and considering policy and public health implications. Through a detailed examination of these interconnected pathways, this review underscores the critical importance of sleep in modulating immune function and cancer outcomes, advocating for interdisciplinary research and clinical strategies to harness this knowledge for improved health outcomes.

Acupuncture for senile insomnia: A systematic review of acupuncture point.

OBJECTIVE: Insomnia is one of the most common diseases among the elderly. The elderly with long-term insomnia are more likely to have symptoms such as vertigo, fatigue, and immunity decline. Acupuncture is increasingly being used to treat insomnia. The purpose of this review is to summarize the critical acupoints in the treatment of senile insomnia and evaluate the effectiveness of the treatment. To provide a research basis for acupuncture treatment of senile insomnia in the future. METHODS: We will search the clinical studies on acupuncture in the treatment of senile insomnia published by CNKI (China National Knowledge Infrastructure), Wanfang (Wan Fang Data Knowledge Service Platform), CSTJ (China Science and Technology Journal Database), Pubmed, and ScienceDirect before December 31, 2023. Acupoint will be analyzed using TCMISS (TCM Inheritance Assistance Platform). RESULTS: 265 literatures were retrieved, and 94 were selected as the criteria. The results showed that there were 90 acupoints related to treatment. The acupoints with the highest frequency were shenmen (HT7), sanyinjiao (SP6), baihui (GV20), zusanli (ST36), neiguan (PC6), xinshu (BL15), taixi (KI3), and sishencong (EX-HN1) anmian (JLSXX-QX), shenshu (BL23). The most frequently used meridians were bladder meridian (BL), governor vessel (GV), and stomach meridian (ST). They were mainly distributed in the lower limbs and head. The most frequent specific points are the five transport points and source points. The most frequently used combinations are "shenmen (HT7) - sanyinjiao (SP6)", "shenmen (HT7) - baihui (GV20)", and "shenmen (HT7) - neiguan (PC6)". Association rule analysis showed that the acupoints with the highest confidence were shenmen (HT7), neiguan (PC6), and sanyinjiao (SP6). Network topology analysis showed that sanyinjiao (SP6), zusanli (ST36), and shenmen (HT7) were the core acupuncture points for the treatment of senile insomnia. CONCLUSION: The primary Acupuncture acupoints for senile insomnia are shenmen (HT7), sanyinjiao (SP6), baihui (GV20), zusanli (ST36), and neiguan (PC6), indicating that these acupoints have a strong correlation with senile insomnia. Sanyinjiao (SP6), zusanli (ST36), and shenmen (HT7) may be the core acupuncture acupoints for the treatment of senile insomnia.

Pain, obesity, adenosine salvage disruption, and smoking behavior mediate the effect of gut microbiota on sleep disorders: results from network Mendelian randomization and 16S rDNA sequencing.

Objectives: The objective of this study is to investigate the indirect causalities between gut microbiota and sleep disorders. Methods: In stage 1, we utilized 196 gut microbiota as the exposure factor and conducted a two-sample univariable Mendelian randomization (MR) analysis on five sleep disorders: insomnia, excessive daytime sleepiness (EDS), sleep-wake rhythm disorders (SWRD), obstructive sleep apnea (OSA), and isolated REM sleep behavior disorder (iRBD). In stage 2, we validated the MR findings by comparing fecal microbiota abundance between patients and healthy controls through 16S rDNA sequencing. In stage 3, we explored the indirect pathways by which the microbiota affects sleep, using 205 gut microbiota metabolic pathways and 9 common risk factors for sleep disorders as candidate mediators in a network MR analysis. Results: In stage 1, the univariable MR analysis identified 14 microbiota potentially influencing five different sleep disorders. In stage 2, the results from our observational study validated four of these associations. In stage 3, the network MR analysis revealed that the Negativicutes class and Selenomonadales order might worsen insomnia by increasing pain [mediation: 12.43% (95% CI: 0.47, 24.39%)]. Oxalobacter could raise EDS by disrupting adenosine reuptake [25.39% (1.84, 48.95%)]. Allisonella may elevate OSA risk via obesity promotion [36.88% (17.23, 56.54%)], while the Eubacterium xylanophilum group may lower OSA risk by decreasing smoking behavior [7.70% (0.66, 14.74%)]. Conclusion: Triangulation of evidence from the MR and observational study revealed indirect causal relationships between the microbiota and sleep disorders, offering fresh perspectives on how gut microbiota modulate sleep.
