Prevalence of fibromyalgia and irritable bowel syndrome and its association with studying medicine, a cross-sectional study in Al-Baath University, Syria. Brain Behav 2024; 14:e3445. [PMID: 38468467 PMCID: PMC10928353 DOI: 10.1002/brb3.3445] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/20/2023] [Revised: 12/17/2023] [Accepted: 02/04/2024] [Indexed: 03/13/2024] Open
Abstract
BACKGROUND The aim of this study is to assess the prevalence rate of fibromyalgia (FM) and irritable bowel syndrome (IBS) among Al-Baath University students and find out whether studying medicine has an association with a higher prevalence rate. METHODS The participants of this observational cross-sectional study were students aged 18-30 years from Al-Baath University. A structured self-estimated electronic questionnaire developed by Google Forms was distributed using social media platforms from 15 February to 15 March, 2023. We used The American College of Rheumatology (ACR) 2016 and Fibromyalgia Rapid Screening Tool criteria to assess the prevalence rate of FM. We used The ROME IV criteria to asses IBS prevalence rate. RESULTS The final sample size was 800 individuals. The prevalence of IBS in the study population was 26.8%. Overall, IBS-Constipation was the most common subtype, and the prevalence rate was higher among medical students (14%) compared to other colleges (12.8%) (p = .002). The difference in IBS prevalence between males and females was (9.3% vs. 17.5%, p = .283), but this did not reach the statistical significance. The prevalence of FM according to The ACR in the study population was 3.6%. Females had higher prevalence rate than males (3.1% vs. 0.5%, p = .007). The prevalence of FM was also higher in other colleges compared to medicine (2.3% vs. 1.4%, p = .547), but this did not reach statistical significance. CONCLUSION We found an increased prevalence of IBS among medical students. The prevalence of FM did not show any relation to studying medicine. We recommend additional prospective studies to assess whether studying medicine could be a risk factor for these disorders or not.

Effects of traditional Chinese exercises in fibromyalgia syndrome: A meta-analysis of randomized controlled trials. Complement Ther Med 2024; 80:103019. [PMID: 38211633 DOI: 10.1016/j.ctim.2024.103019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Revised: 11/25/2023] [Accepted: 01/03/2024] [Indexed: 01/13/2024] Open
Abstract
OBJECTIVES To explore the efficacy and safety of five traditional Chinese exercises (TCEs) in patients with fibromyalgia syndrome (FMS). METHODS The PubMed, Embase, Scopus, ProQuest, Web of Science, Cochrane, CNKI, WanFang, and VIP databases were comprehensively searched for randomized controlled trials (RCTs) related to TCEs published from inception until February 2023. Standardized mean differences (SMD) and 95% confidence intervals (CI) were used to determine the combined effects of the intervention, and the Cochrane risk-of-bias assessment tool and Review 5.2 software were used to assess methodological quality. The data were extracted and analyzed by the Stata15.0 random effects model. RESULTS Nineteen RCTs including 1315 participants were included in the analysis. The studies were found to be heterogeneous (I2 =86.2, P = 0.000), and thus a random effects model was used to combine the data. The results showed that traditional Chinese exercises had potentially beneficial effects on reducing pain (SMD =-0.66,95% CI [-1.08, -0.25], P = 0.002), improving sleep (SMD = -0.35,95% CI [-0.68,0. 01], P = 0.041) and relieving depression (SMD= -0.24,95% CI [-0.47, -0.02], P = 0.034) in FMS patients. However, no significant effects were found on improved quality of life (SMD =-0.20,95% CI [-0.48,0.09], P = 0.176). CONCLUSIONS TCEs can improve pain, sleep quality and depression in patients with FMS and are safe. However, they do not improve the quality of life significantly. Further large-scale, high-quality, and multi-center RCTs are required to verify the efficacy of TCEs.

Sleep profile and its correlation with clinical variables in fibromyalgia syndrome: A cross-sectional study. J Taibah Univ Med Sci 2024; 19:90-98. [PMID: 37876596 PMCID: PMC10590848 DOI: 10.1016/j.jtumed.2023.08.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2023] [Revised: 07/26/2023] [Accepted: 08/31/2023] [Indexed: 10/26/2023] Open
Abstract
Objective A scarcity of literature exists on sleep quality in fibromyalgia syndrome (FMS) in Indian patients. The current study described the sleep profile of patients with FMS with poor sleep quality residing in urban Bangalore and determined the relationship between poor sleep and fibromyalgia variables. Methods Eighty-six patients with FMS were included in the study. Pittsburgh Sleep Quality Index (PSQI) and Revised Fibromyalgia Impact Questionnaire (FIQR) were used to evaluate the sleep profile and fibromyalgia variables. Spearman's rank correlation, t-test, and one-way analysis of variance were used for the analyses. Results Ninety-one percent of patients with FMS were identified as poor sleepers (PSQI >5). The mean PSQI global score of the included patients was 12.04 ± 3.5. The global sleep score varied with sex (p = 0.003) and fibromyalgia severity (p = 0.001). A significant correlation was found between PSQI global score and FIQR total score (r = 0.4, p < 0.001), FIQR subdomains (r = 0.2-0.4, p < 0.05), and FMS duration (r = 0.26, p < 0.05). The PSQI global score was also correlated with pain, depression, memory, anxiety, balance, and sensitivity (r = 0.2-0.3, p < 0.05). Conclusion Sleep disturbance is highly prevalent in patients with FMS residing in urban Bangalore. Sleep quality tends to worsen in females with increasing FMS severity and duration but does not differ across other demographic variables. Sleep quality is significantly correlated with somatic as well as psychological variables. Future studies evaluating the predictors of poor sleep are needed to further corroborate these findings.

Abstract
BACKGROUND Temporomandibular joint disorders (TMDs) are common in young adults, and the link between chronotype profile and TMDs is unclear. OBJECTIVE This study examined TMD prevalence and chronotype distribution and explored the relationship between chronotype and TMDs in young adults. MATERIALS AND METHODS A total of 663 students from Sichuan University completed questionnaires. Chronotype profiles were assessed using the Morningness-Eveningness Questionnaire, and TMDs were screened using the Fonseca Memory Index. To validate the findings, 68 TMD patients and 136 controls were enrolled. RESULTS The prevalence of TMDs was 69.7%, with significant differences among chronotype profiles. The intermediate profile was the most common chronotype. Eveningness profile was associated with higher TMDs prevalence and severity. Muscle pain and side movement difficulty scores were higher in eveningness and intermediate profiles. Female gender (OR 2.345; 95% CI 1.668-3.297) was a TMD risk factor, while morningness profile (OR 0.537; 95% CI 0.297-0.970) was protective. Validation with TMD patients and controls supported these findings, showing higher eveningness profile prevalence in the TMD groups. CONCLUSIONS TMDs have a high prevalence in college students, chronotype profiles shown to be associated with TMDs. Morningness is the protection factor in TMDs and PT, eveningness is a risk factor for IT.

Influence of socio-affective factors on quality of life in women diagnosed with fibromyalgia. Front Psychol 2023; 14:1229076. [PMID: 38023047 PMCID: PMC10664247 DOI: 10.3389/fpsyg.2023.1229076] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2023] [Accepted: 10/13/2023] [Indexed: 12/01/2023] Open
Abstract
Introduction Fibromyalgia is a disease that involves chronic pain, with high prevalence in the female population and great impact on the bio-psycho-social sphere of people affected by it. However, few studies have analyzed the possible influence of socio-affective factors on the quality of life of people who suffer from this disease. Objective The aim of this study was to determine the relationships between the impact of this disease on the lives of people with fibromyalgia and these variables. Specifically, we analyzed the quality of partner relationship, perceived loneliness, life satisfaction, and perceived socio-family situation. Method A descriptive-correlational cross-sectional design was used. The sample consisted of 69 women diagnosed with fibromyalgia. The participants completed different questionnaires that measured their happiness, satisfaction with life, perceived loneliness, quality of partner relationship, socio-family valuation, and the impact of fibromyalgia. Results The quality of partner relationship, perceived loneliness and socio-family valuation seem to be good predictors of subjective happiness, life satisfaction, and the impact that fibromyalgia has on people's lives, in the sense that the more positive the valuation of the couple relationship and of the socio-family situation, and the lower the perceived loneliness, people feel happier, more satisfied with their lives and the lower the impact that fibromyalgia has on their lives. Conclusion The 50% of satisfaction with life can be explained from the scores obtained in perceived loneliness and the quality of partner relationship. In this sense, perceived loneliness was a good predictor of the impact of fibromyalgia on the lives of these patients.

Medium- and Long-Term Effects of Insomnia Severity and Circadian Preference on Pain and Emotional Distress Among Individuals With Chronic Pain. THE JOURNAL OF PAIN 2023; 24:1946-1956. [PMID: 37286095 PMCID: PMC10615674 DOI: 10.1016/j.jpain.2023.05.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/13/2022] [Revised: 05/21/2023] [Accepted: 05/31/2023] [Indexed: 06/09/2023]
Abstract
Studies have identified insomnia as having significant influence on chronic pain. A rising body of research has also underscored the association between eveningness and chronic pain. However, co-assessment of insomnia and eveningness in the context of chronic pain adjustment has been limited. The present study sought to investigate the effects of insomnia and eveningness on pain severity, pain interference, and emotional distress (ie, depressive and anxiety symptoms) over nearly 2 years among adults with chronic pain in the U.S. Adults with chronic pain (N = 884) were surveyed 3 times via Amazon's MTurk online crowdsourcing platform: baseline, 9-month follow-up, and 21-month follow-up. Path analysis was conducted to examine the effects of baseline insomnia severity (Insomnia Severity Index) and eveningness (Morningness and Eveningness Questionnaire), as well as their moderating effects on outcomes. Controlling for select sociodemographic variables and baseline outcome levels, greater insomnia severity at baseline was associated with worsening of all of the pain-related outcomes at 9-month follow-up, and pain interreference and emotional distress at 21-month follow-up. We did not find evidence that evening types are at a higher risk of experiencing worsening pain-related outcomes over time compared to morning and intermediate types. There were also no significant insomnia severity and eveningness moderation effects on any outcome. Our findings suggest that insomnia is a more robust predictor of changes in pain-related outcomes as compared to eveningness. Treatment of insomnia can be important in chronic pain management. Future studies should evaluate the role of circadian misalignment on pain using more accurate biobehavioral makers. PERSPECTIVE: This study examined the effects of insomnia and eveningness on pain and emotional distress in a large sample of individuals with chronic pain. Insomnia severity is a stronger predictor of changes in pain and emotional distress than eveningness, highlighting insomnia as an important clinical target for chronic pain management.

Abstract
This study aimed to examine the relationship between acne severity and quality of life, insomnia, and chronotype. This study included 151 patients diagnosed with acne vulgaris, aged 18-30 years. A sociodemographic data form was completed by the clinician, and acne severity was evaluated using the Global Acne Grading System (GAGS). The Visual Analogue Scale (VAS), Acne Quality of Life Scale (AQLS), Hospital Anxiety Depression Scale (HADS), Insomnia Severity Index (ISI), and Morningness-Eveningness Questionnaire (MEQ) were completed by the participants. There was a significant difference between the MEQ scores of the participants who were divided into three groups according to the severity of global acne, as mild, moderate, and severe. In the post hoc analysis, the MEQ scores of the patients with mild acne were determined to be significantly higher than the scores of the patients with moderate and severe acne. A statistically significant negative correlation was observed between the GAGS scores and the MEQ scores. In addition, a statistically significant positive correlation was found between the participants' ISI scores and AQLS scores. Considering the variables related to chronotype and sleep in the treatment planning for patients with acne vulgaris may be appropriate within the scope of integrative treatment.

Abstract
BACKGROUND Patients with glaucoma may experience many symptoms such as blindness, which seriously affect their quality of life (QoL). Resilience is playing a vital role in enhancing the QoL and well-being of patients with chronic diseases. In addition, sleep disturbance is common in patients with glaucoma, leading to a decline in their QoL. However, there is a dearth of research on whether sleep disturbance plays a mediating role between resilience and QoL among glaucoma patients. OBJECTIVE The aim of this study is to explore the role of sleep disturbance in the relationship between resilience and QoL among glaucoma patients. METHODS From July to December 2019, a cross-sectional survey was conducted on 215 glaucoma patients in an ophthalmic hospital in Liaoning Province. Hierarchical multiple regression (HMR) analyses and structural equation modeling (SEM) were conducted to examine the factors related to QoL and to test the hypothesis that sleep disturbance mediates the relationship between resilience and QoL among glaucoma patients. RESULTS The average QoL score among glaucoma patients was 43.85 ± 14.97 as reported by the Glaucoma Quality of Life-15 (GQL-15) scale, where a higher scores indicating a poorer QoL. Resilience was found to be linked with a lower QoL score (P < 0.01), while sleep disturbance was associated with a higher QoL score (P < 0.01). When sleep disturbance was included in the model as partial mediator, the path coefficients for the association between resilience and QoL score was significantly decreased (a*b = -0.1, BCa95% CI: -0.154∼-0.045). CONCLUSION Findings of this study reflected that QoL among glaucoma patients in China was poor. Resilience was found to be an important positive factor, which could result in the improvement of QoL. Furthermore, sleep disturbance mediated the relationship between resilience and QoL among patients with glaucoma, thereby reducing the positive impact of resilience on QoL in glaucoma patients. Efforts to improve QoL among glaucoma patients may benefit from interventions that enhance the levels of resilience and promote healthy sleep.

Eveningness intensifies the association between musculoskeletal pain and health-related quality of life: a Northern Finland Birth Cohort Study 1966. Pain 2022; 163:2154-2161. [PMID: 35135992 PMCID: PMC9578528 DOI: 10.1097/j.pain.0000000000002609] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2021] [Revised: 01/16/2022] [Accepted: 01/31/2022] [Indexed: 11/25/2022]
Abstract
ABSTRACT People with an evening (E)-type preference (ie, chronotype) experience musculoskeletal (MSK) pain and reduced health-related quality of life (HRQoL) more often than morning (M) types. Musculoskeletal pain is a well-established contributor to reduced HRQoL. This study aimed to evaluate whether eveningness amplifies the association between MSK pain and HRQoL in contrast to morningness. Questionnaire data on MSK pain dimensions (intensity, disability at work, number of pain sites [NPSs], and frequency), chronotype, covariates (sex, sufficiency of sleep duration, mental distress, and presence of coexisting diseases), and HRQoL (measured by 15D) were collected among 46-year-old individuals belonging to the Northern Finland Birth Cohort 1966 (N = 4257). Individuals without any MSK pain were excluded. General linear models were conducted to estimate the associations between chronotypes, MSK pain dimensions, and HRQoL. The interaction terms (chronotype × pain dimension) were tested in the models. There were 13% E-types and 43% M-types in the study sample. Each pain dimension and chronotype were related to HRQoL. In the sex-adjusted chronotype-specific models, the reduction in HRQoL in relation to pain appeared to be stronger among E-types than among M-types in respect to all pain dimensions. After adjustments, this was particularly seen in terms of NPS and pain frequency. Our findings suggest that eveningness intensifies the association between MSK pain and HRQoL, and, thus, they are indicative of E-types being more sensitive than M-types to the consequences of MSK pain. As such, MSK pain treatment and rehabilitation actions to improve HRQoL should be especially targeted at E-types.

Abstract
The circadian rhythm is crucial for physiological and behavioral functions. Chronotype, which represents individual preferences for activity and performance, is associated with human health issues, particularly psychiatric disorders. This narrative review, which focuses on the relationship between chronotype and mental disorders, provides an insight into the potential mechanism. Recent evidence indicates that (1) the evening chronotype is a risk factor for depressive disorders and substance use disorders, whereas the morning chronotype is a protective factor. (2) Evening chronotype individuals with bipolar disorder tend to have more severe symptoms and comorbidities. (3) The evening chronotype is only related to anxiety symptoms. (4) The relationship between chronotype and schizophrenia remains unclear, despite increasing evidence on their link. (5) The evening chronotype is significantly associated with eating disorders, with the majority of studies have focused on binge eating disorders. Furthermore, the underlying mechanisms or influence factors are described in detail, including clock genes, brain characteristics, neuroendocrinology, the light/dark cycle, social factors, psychological factors, and sleep disorders. These findings provide the latest evidence on chronotypes and psychiatric disorders and serve as a valuable reference for researchers.

Abstract
BACKGROUND It has been suggested that chronotype, the individual preference for 24-hour circadian rhythms, influences health. Sleep problems and mental distress are among the greatest risk factors for musculoskeletal (MS) pain. The aims of this study were first, to explore the associations between chronotypes and MS pain, with special reference to disabling MS pain, and second, to test whether mental distress and insomnia have a modifying role in the associations between chronotypes and MS pain. METHODS The dataset of 4,961 individuals was composed of Northern Finns surveyed on MS pain, chronotypes, and confounding factors (sex, insomnia, sleep duration, smoking, mental distress, occupational status, education level, and number of co-existing diseases) at 46 years. The relationships between chronotypes (evening [E], intermediate [I], and morning [M]) and MS pain were evaluated using multinomial logistic regression. To address the second aim, we included an interaction term (chronotype*mental distress, chronotype*insomnia) in the logistic model. RESULTS Compared to the M-types, both the E- and I-types had increased odds of suffering 'disabling pain' in the unadjusted model (odds ratio [OR] 1.79, 95% confidence interval [CI] 1.37-2.33; OR 1.54, 95% CI 1.29-1.84, respectively). However, the association remained statistically significant only after adjusting for all covariates among the I-types (OR 1.39, 95% CI 1.15-1.67). Neither mental distress nor insomnia was found to modify the chronotype-MS pain association. CONCLUSIONS The results highlight the importance of chronotypes for individuals' MS health but suggest the presence of confounding factors in the interplay between these factors.

Abstract
OBJECTIVE To measure the prevalence and cumulative incidence of individuals diagnosed with fibromyalgia (FM) in Catalonia between 2010 and 2017. METHODS A retrospective observational study of the population of Catalonia between 2010 and 2017, both included, was designed to describe the incidence, prevalence, and sociodemographic characteristics of individuals diagnosed with fibromyalgia. A total of 56 098 patients were included in the study. The scope of the study were the 283 Primary Care Teams (PCT), all managed by the Instituto Catalán de la Salud [Catalan Institute of Health] (ICS). RESULTS The diagnosis of FM is higher in females (95.4%) than males (4.55%), with a mean age of 53.0 [45.0-61.0] years. The prevalence of FM in the total population was 0.4% in 2010 and 1.4% in 2017. The highest prevalence was found in the 55 to 65 age group (1.05% in 2010, and 2.46% in 2017). A relationship was found between the prevalence of FM and the degree of socioeconomic deprivation in urban areas: the greater the deprivation, the greater the prevalence of FM. The cumulative incidence of FM in the population remained constant over time (0.11% in 2010 and 0.10% in 2017), being more prevalent in women than men (0.18% women, 0.01% men in 2017). CONCLUSIONS Our study confirms that FM is a prevalent disease in Catalonia, with an upward trend in recent years and it is more prevalent in women.

Abstract
Background Previous studies have shown that morning types are less sensitive to pain. This study aimed to examine the relationship between chronotypes and musculoskeletal problems in workers with musculoskeletal burdens at work. Methods This cross-sectional study included 119 male production workers from a large automobile manufacturing plant. All the participants worked 2 shifts and worked on the automobile assembly line. Data were obtained using structured questionnaires, including the reduced Morningness-Eveningness Questionnaire (rMEQ), and musculoskeletal symptom questionnaire. Participants with an rMEQ score of 18 points or more were defined as morning-type workers (MTWs). Participants whose scores were less than 18 points were defined as neither-type workers (NTWs). Results The arithmetic mean age was 51.8 ± 5.3 years. MTWs and NTWs accounted for 35.3% and 64.7% of the total participants, respectively. Evening- and intermediate-type workers accounted form 6.7% and 58.0% of the participants, respectively. There was no significant difference in the health indicators when the MTW and NTW groups were compared. However, the musculoskeletal symptom questionnaire demonstrated a significant difference between the MTW and NTW groups. In the preceding year, the MTW group had significantly lower musculoskeletal pain and treatment ratios compared to the NTW group (35.7% vs. 62.3%, p = 0.005 and 14.3% vs. 32.5%, p = 0.031, respectively). After adjusting for variables, the odds ratio (OR) for musculoskeletal pain was significantly higher in the NTW group than in the MTW group (OR, 3.112; 95% confidence interval, 1.285–7.535; p = 0.012). Conclusions In this study, the musculoskeletal pain ratio was significantly lower for MTWs when compared to NTWs. Chronotypes could play an important role in work-related musculoskeletal disorders. Further, larger-scale, follow-up studies on chronotypes are required to assist in the prevention of musculoskeletal disorders in future.

Working Memory Performance, Pain and Associated Clinical Variables in Women With Fibromyalgia. Front Psychol 2021; 12:747533. [PMID: 34744922 PMCID: PMC8566754 DOI: 10.3389/fpsyg.2021.747533] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2021] [Accepted: 09/20/2021] [Indexed: 01/08/2023] Open
Abstract
Working memory (WM) is a critical process for cognitive functioning in which fibromyalgia (FM) patients could show cognitive disturbances. Dyscognition in FM has been explained by interference from pain processing, which shares the neural substrates involved in cognition and may capture neural resources required to perform cognitive tasks. However, there is not yet data about how pain is related to WM performance, neither the role that other clinical variables could have. The objectives of this study were (1) to clarify the WM status of patients with FM and its relationship with nociception, and (2) to determine the clinical variables associated to FM that best predict WM performance. To this end, 132 women with FM undertook a neuropsychological assessment of WM functioning (Digit span, Spatial span, ACT tests and a 2-Back task) and a complete clinical assessment (FSQ, FIQ-R, BDI-1A, HADS, PSQI, MFE-30 questionnaires), including determination of pain thresholds and tolerance by pressure algometry. Patients with FM seem to preserve their WM span and ability to maintain and manipulate information online for both visuospatial and verbal domains. However, up to one-third of patients showed impairment in tasks requiring more short-term memory load, divided attention, and information processing ability (measured by the ACT task). Cognitive performance was spuriously related to the level of pain experienced, finding only that pain measures are related to the ACT task. The results of the linear regression analyses suggest that sleep problems and fatigue were the variables that best predicted WM performance in FM patients. Future research should take these variables into account when evaluating dyscognition in FM and should include dynamic measures of pain modulation.

Diurnal preference and depressive symptomatology: a meta-analysis. Sci Rep 2021; 11:12003. [PMID: 34099766 PMCID: PMC8184740 DOI: 10.1038/s41598-021-91205-3] [Citation(s) in RCA: 24] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2021] [Accepted: 05/24/2021] [Indexed: 02/05/2023] Open
Abstract
Eveningness, a preference for later sleep and rise times, has been associated with a number of negative outcomes in terms of both physical and mental health. A large body of evidence links eveningness to Major Depressive Disorder (MDD). However, to date, evidence quantifying this association is limited. The current meta-analysis included 43 effect sizes from a total 27,996 participants. Using a random-effects model it was demonstrated that eveningness is associated with a small effect size (Fisher's Z = - 2.4, 95% CI [- 0.27. - 0.21], p < 0.001). Substantial heterogeneity between studies was observed, with meta-regression analyses demonstrating a significant effect of mean age on the association between diurnal preference and depression. There was also evidence of potential publication bias as assessed by visual inspection of funnel plots and Egger's test. The association between diurnal preference and depression is small in magnitude and heterogenous. A better understanding of the mechanistic underpinnings linking diurnal preference to depression and suitably powered prospective studies that allow causal inference are required.

Abstract
It was hypothesized that an individual's chronotype profile has an effect on the performance of work or study tasks. Dental students have to cope with both academic and clinical workloads, and the latter requires extra concentration. The first aim was to evaluate the association of sleep bruxism (SB) and awake bruxism (AB) with sleep related items, temporomandibular disorder (TMD) complaints, and chronotype profile; the second aim was to evaluate the association between complaints of TMD and chronotype profile among dental students. The present cross-sectional descriptive study involved 218 dental students whose ages ranged between 18 and 30 years. In order to gather data, students were required to respond to a questionnaire, which aimed to evaluate possible SB and possible AB occurrence and demographics, sleep-related items and complaints of TMD. For the assessment of the chronotype profile, the morningness-eveningness questionnaire (MEQ) was used. The chi-square test, the Mann-Whitney U test, and t-test analyses were performed to evaluate the factors associated with SB, AB and chronotype profile. The frequency of self-reported SB was 25.2% and AB was 28.9%. The prevalence in the eveningness profile who reported possible AB was 45.3%, while it was 24.2% in intermediate individuals and 18.8% in the morningness profile. An association was also found between possible AB and eveningness chronotype profile (p = .009). No association was found between other temporomandibular joint (TMJ) pain and noise and chronotype profiles (p > .05). An association was found between possible AB and eveningness chronotype profile but no association was found between possible SB and chronotype profile. Moreover, complaint of TMD (face, head, neck pain) was observed particularly in students with an eveningness profile.

Prevalence of sleep disturbances in patients with chronic non-cancer pain: A systematic review and meta-analysis. Sleep Med Rev 2021; 57:101467. [PMID: 33827029 DOI: 10.1016/j.smrv.2021.101467] [Citation(s) in RCA: 40] [Impact Index Per Article: 13.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2020] [Revised: 01/29/2021] [Accepted: 02/01/2021] [Indexed: 12/16/2022]
Abstract
In individuals with chronic pain, sleep disturbances have been suggested to increase suffering, perception of pain, and to negatively affect long-term prognosis. This systematic review and meta-analysis aims to determine the pooled prevalence of sleep disturbances in chronic non-cancer pain patients with no other sleep disorders, using the patient-rated questionnaires Pittsburgh Sleep Quality Index (PSQI) and Insomnia Severity Index (ISI). Multiple databases were searched for studies reporting the prevalence of sleep disturbances in chronic pain patients. The meta-analysis was conducted to examine the pooled prevalence of PSQI and ISI data using the inverse-variance random-effects model and to examine mean differences in PSQI scores. The systematic search resulted in 25,486 articles and 20 were included for analysis. In 12 studies using PSQI, the pooled prevalence of sleep disturbance was 75.3% among 3597 chronic pain patients. In eight studies using ISI, the pooled prevalence was 72.9% among 2578 chronic pain patients. The meta-analysis showed a significant mean difference of 2.75 (p < 0.001) in the global PSQI score between the chronic pain group versus the non-chronic pain group. The relatively high prevalence of sleep disturbances in chronic pain patients emphasizes the importance of further characterizing the relationship between sleep and chronic pain.

Abstract
Sleep deficiency is well-documented in individuals with irritable bowel syndrome (IBS). Sleep deficiency includes poor sleep quality and an inadequate amount of sleep, and is a modifiable risk factor for IBS symptom exacerbations. Prior studies in other populations have identified chronotype and social jetlag (SJL) as important determinants of sleep outcomes. However, chronotype and SJL have not been examined in women with IBS. We used multiple linear regression analyses to determine whether chronotype and SJL are associated with sleep outcomes during weekdays among women with IBS predominant constipation (IBS-C), IBS with predominant diarrhea (IBS-D), and healthy control (HC) women. This sample included 62 women with IBS (IBS-C = 29, IBS-D = 33) and 58 HC women who completed a 28-day daily diary from two study cohorts. The average age of the participants was 30.1 (SD 7.2) years. Chronotype was estimated from daily diary data with the average mid-sleep time on weekends (MSWwe). SJL was calculated by subtracting the average mid-sleep time on weekdays from MSWwe. Sleep outcomes included diary assessments of sleep quality, sleep need met, and restorative sleep during weekdays. In HCs, later chronotype was predictive of lower sleep quality (β = -0.19, p < .01), a perception of sleep need not met (β = -0.17, p < .001), and a less restorative sleep during weekdays (β = -0.15, p = .073), whereas SJL was not associated with sleep outcomes. Similar to HCs, earlier chronotypes in women with IBS-C reported better sleep quality and more sufficient sleep need met and restorative sleep during weekdays than later chronotypes (all p > .05). Compared to HCs, the relationships of chronotype with weekday sleep outcomes in the women with IBS-D were in the opposite directions (all p < .05). This exploratory study suggests that chronotype expression may reflect the temporal associations of sleep outcomes within IBS bowel pattern predominance subgroups, particularly sleep quality and sleep need met. Additional investigations are warranted to examine whether specific temporal attributes of symptoms and/or symptom severity associated with IBS subgroups contribute to chronotype expression.

Abstract
Background and objective Fibromyalgia (FM) is a chronic, multifactorial pain condition. The latest literature suggests that genetic and environmental factors including continuous stress contribute significantly to FM's pathophysiology. In this study, we aimed to investigate the prevalence of FM among medical students as they are considered a population significantly at risk of developing the condition. Methods This cross-sectional study was conducted at King Abdulaziz University. Medical students included in the study were recruited through a random stratified sampling method. A self-administered questionnaire was distributed to the participants; it included questions related to widespread pain index (WPI) and symptom severity scale (SSS) to assess the symptoms and diagnosis of FM, which were established based on the current diagnostic criteria. All first-year students were excluded from this research. Results A total of 450 participants were recruited for the study. Among them, 291 (64.7%) were females and 159 (35.3%) were males. Their ages ranged from 18 to 26 years, and the mean age was 21.52 years (SD: ±1.52). They came from different academic levels: 97 (21.6%) were in the second year, 79 (17.6%) were in the third year, 70 (15.6%) were in the fourth year, 99 (22%) were in the fifth year, and 105 (23.3%) were in the sixth year. The overall prevalence of FM was found to be 43 (9.6%). It was established based on the number of students who fulfilled the diagnostic criteria or were previously diagnosed with FM by a professional physician. Conclusion FM is highly prevalent among medical students. Our findings demonstrate the likelihood of the influence of medical school on causing the condition, as it has a stressful education system with high academic expectations. We recommend that this issue be seriously addressed since FM leads to a significant burden on the students and can negatively affect their future medical practice.

Abstract
The aim of the present study was to evaluate whether anxiety and insomnia symptoms, somatic symptoms, and social dysfunction mediate the link between chronotype and suicidality, as depressive symptoms are known to do, among students of the faculties of Medicine and Psychology. Data from a total of 289 students were eligible for the analysis. The students completed the Suicide Behaviors Questionnaire - Revised, Composite Scale of Morningness, General Health Questionnaire. Single-predictor linear regression models were created to predict suicidality, with a subsequent mediation analysis. A preference toward eveningness was associated with an increase in suicidality Somatic symptoms, anxiety/insomnia, and depressive symptoms fully mediated the relationship between chronotype and suicidality. Depressive symptoms were found to present the strongest effect size of mediation. Social dysfunction was associated with both eveningness and suicidality, but did not play a mediating role. There might be a need to evaluate nonpsychotic mental health indices other than depressive symptoms when assessing the link between suicidality and chronotype among students of the faculties of Medicine and Psychology.

Efficacy and Safety of ASP0819 in Patients with Fibromyalgia: Results of a Proof-of-Concept, Randomized, Double-Blind, Placebo-Controlled Trial. J Pain Res 2020; 13:3355-3369. [PMID: 33328761 PMCID: PMC7735791 DOI: 10.2147/jpr.s274562] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2020] [Accepted: 10/30/2020] [Indexed: 11/23/2022] Open
Abstract
PURPOSE ASP0819 is a novel, non-opioid KCa3.1 channel opener that reverses abnormal nerve firing of primary sensory afferent nerves. Currently available treatments for fibromyalgia provide only modest relief and are accompanied by a host of adverse side effects. PATIENTS AND METHODS In this phase 2a, double-blind trial (NCT03056690), adults meeting fibromyalgia diagnostic criteria were randomized 1:1 to receive either 15 mg/day of oral ASP0819 (n=91) or placebo (n=95). The primary endpoint was the change from baseline to Week 8 in the mean daily average pain score. Changes in the Fibromyalgia Impact Questionnaire Revised (FIQR) symptoms, function, and overall impact subscales, as well as changes in the patients' global impression of change, were secondary endpoints; treatment effects on FIQR total score and impact on sleep were exploratory analyses. RESULTS There was no statistically significant difference between ASP0819 and placebo for the primary endpoint (P=0.086); however, ASP0819 versus placebo significantly improved daily average pain at Weeks 2, 6, and 7 (all P<0.05). Numerical improvements were observed on the FIQR total score and several sleep items showed statistically significant improvements with ASP0819 versus placebo. There were no major safety concerns with ASP0819. Headache was the most common treatment-emergent adverse event (TEAE) occurring in both study arms; most TEAEs were mild or moderate in severity and no TEAEs suggestive of potential drug abuse were observed, as assessed by TEAE reporting and/or safety evaluations. Withdrawal effects also were not observed. CONCLUSION ASP0819 demonstrated some signals suggestive of efficacy and had a good tolerability profile in patients with fibromyalgia. Further studies are required to determine if ASP0819 can be a novel non-opioid treatment option in this patient group. CLINICALTRIALSGOV REGISTRATION NCT03056690.

Patient Reported Outcome Measures of Sleep Quality in Fibromyalgia: A COSMIN Systematic Review. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:E2992. [PMID: 32357398 PMCID: PMC7246509 DOI: 10.3390/ijerph17092992] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/24/2020] [Revised: 04/22/2020] [Accepted: 04/23/2020] [Indexed: 12/26/2022]
Abstract
Poor sleep quality is a common concern and a troublesome symptom among patients suffering from fibromyalgia. The purpose of this review was to identify and describe the available patient reported outcome measures (PROMs) of sleep quality validated in adult people diagnosed with fibromyalgia. The COSMIN and PRISMA recommendations were followed. An electronic systematized search in the electronic databases PubMed, Scopus, CINAHL Plus, PsycINFO, and ISI Web of Science was carried out. Validation studies of PROMs of sleep quality in fibromyalgia published in English or Spanish were included. The selection of the studies was developed through a peer review process through the online software "COVIDENCE". The quality of the studies was assessed using the COSMIN Risk of Bias checklist. A total of 5 PROMs were found validated in patients with fibromyalgia: (1) Pittsburgh Sleep Quality Index (PSQI), (2) Jenkins Sleep Scale (JSS), (3) Sleep Quality Numeric Rating Scale (SQ-NRS), (4) Medical Outcomes Study-Sleep Scale (MOS-SS), and (5) Fibromyalgia Sleep Diary (FSD). The quality of the evidence was very good and the quality of the results ranged from moderate to high. All the included PROMs, except for the FSD, showed adequate psychometric properties and, therefore, are valid and reliable tools for assessing sleep quality in the context of FM. However, none of the studies analyzed all the psychometric properties of the included PROMs as established in the COSMIN guidelines, highlighting that this is a potential field of research for future investigations.
