Sleep disturbances, fatigue and psychological health in women with endometriosis: a matched pair case-control study

Insights into endometriosis symptom trajectories and assessment of surgical intervention outcomes using longitudinal actigraphy

Endometriosis is a common, chronic condition associated with debilitating pain, fatigue, and heterogeneous symptom presentation. In this exploratory study, 68 participants with confirmed endometriosis were monitored for up to three 4-6-week smartwatch cycles. We collected daily self-reports of pain and fatigue as well as retrospective questionnaires assessing quality of life, and we extracted daily measures of physical activity (PA), sleep, and diurnal rhythms from wrist-worn actigraphy data. We found that daily PA was strongly negatively correlated with self-reported fatigue (repeated measures correlations R < - 0.3 ) and that participants with more severe or variable symptom trajectories displayed lower levels of PA, greater sleep disturbance, and more disrupted sleep and activity rhythms (Spearman's |R| > 0.3 ). Lastly, we found evidence of sleep and PA changes following surgery for endometriosis that reflected change in self-reported symptoms. Collectively, our findings suggest that passive data collection using wrist-worn wearables in endometriosis could facilitate individualized objective insights into symptom trajectories.

Perceived cognitive functioning difficulties in individuals living with endometriosis

Difficulties in cognitive functioning (e.g., memory, attention) are common in chronic conditions characterized by physical pain, fatigue and depression. Yet investigations in endometriosis are lacking. We aimed to assess: (1) perceived cognitive functioning, (2) the association of cognitive functioning with fatigue, pain and depressive symptoms, and (3) whether endometriosis treatments moderated these relationships. Participants (n = 1239) with diagnosed endometriosis completed an online survey assessing perceived cognitive functioning [Functional Assessment of Cancer Therapy-Cognitive Function (FACT-Cog)], pain, fatigue and depression. FACT-Cog scores indicated cognitive impairments in 80% of participants. Hierarchical regression analyses demonstrated that greater pain, fatigue, and depressive symptoms were associated with poorer perceived cognitive functioning. Moderation analyses indicated that taking hormonal treatments or pain medications diminished the adverse effects of depression, but exacerbated the adverse effects of pain, on cognitive functioning. The extensive perceived cognitive difficulties evident in this sample suggests that supportive interventions to enhance cognitive functioning may be warranted.

Sleep Health and Psychological Wellbeing in Adult Women: A Specific Focus on Endometriosis-A Survey Study

Background: Endometriosis is a chronic, oestrogen-sensitive inflammatory disease, which can have a significant impact on women's wellbeing. Nevertheless, the sleep health of this population has been poorly investigated. This exploratory study aimed at describing sleep health, psychological wellbeing, and prevalence of endometriosis among a sample of female students and at evaluating the impact of endometriosis on sleep health and psychological wellbeing in women suffering from the disease. Methods: Women were recruited with a two-stage procedure in a cross-sectional study using online questionnaires: Insomnia Severity Index, Hospital Anxiety and Depression Scale, and Difficulties in Emotion Regulation Scale-Short form. Furthermore, specific questions were used to measure the five dimensions of sleep health: satisfaction, vigilance, efficiency, duration, and timing. Results: In the first stage of the enrolment procedure, 1068 students (18-45 years old) responded to the questionnaire, and 8.7% reported a physician diagnosis of endometriosis. Additionally, in the second stage of the enrolment procedure, 75 women were recruited through social media and reported a diagnosis of endometriosis. Then, all women with endometriosis (169) were age-matched with 169 women without the disease. Multivariate regression analyses showed a bidirectional association between sleep health and psychological wellbeing in the matched sample. Independent samples t-test showed that women with endometriosis reported more severe insomnia symptoms and lower psychological wellbeing than controls. Statistically significant differences were also found in global sleep health and satisfaction, vigilance, and efficiency. Among women with endometriosis, pain and anxiety symptoms were bidirectionally associated, while sleep health was significantly associated with disease stage and psychological difficulties. Conclusions: Considering and treating sleep difficulties in this population may contribute to an improvement in psychological wellbeing and quality of life.

Association of Sleep Traits, Physical Activity, and Sedentary Leisure Behavior With Female Reproductive Health: A Two-Sample Mendelian Randomization Analysis

Purpose

Living habits affect female endocrine function and fertility, along with aging and other life factors. Because of this, female reproductive health can be promoted through living habit adjustment.

Methods

We used two-sample Mendelian randomization analysis with summary datasets from a genome-wide association study to investigate the causal relationships between sleep traits, sedentary leisure behavior, physical activity, and reproductive health traits in women, calculating odds ratios (ORs) and 95% confidence intervals (CIs). Exposure genetic instruments were used for variants that were significantly related to traits. The inverse-variance weighted (IVW) method was used for the main analysis, and we also performed MR-Egger and weighted median analyses to supplement the sensitivity test. Horizontal pleiotropy was detected using the MRE intercept and MR-PRESSO methods, and heterogeneity was assessed using Cochran's Q statistics, IVW, and MR-Egger.

Results

Insomnia showed a significant inverse causal association with endometriosis [OR (95% CI) IVW = 1.80 (1.16, 2.80), P = 0.009] and abnormal menstruation [OR (95% CI) IVW = 2.37 (1.34, 4.20), P = 0.003]. Sleep duration was negatively related to menopause age (beta IVW = -0.034, P = 0.001), and long sleep duration could be a protective factor of endometriosis [OR (95% CI) IVW = 0.07 (0.01, 0.72), P = 0.024]. Strenuous sports were also negatively correlated with female infertility [OR (95% CI) IVW = 0.10 (0.02, 0.68), P = 0.019]. Sensitivity analysis revealed no signs of horizontal pleiotropy or heterogeneity.

Conclusion

Our findings suggest that insomnia is an adverse factor correlated with endometriosis and abnormal menstruation and that longer sleep duration protects against endometriosis. Adequate sleep and regular schedules may decrease the risk of endometriosis and abnormal menstruation, helping improve the reproductive health of women.

Factor Structure of the Brief Pain Inventory-Short Form in African American Older Adults With Osteoarthritis

PURPOSE

To evaluate the factor structure of the Brief Pain Inventory-Short Form (BPI-SF) and measurement invariance across two age groups for African American (AA) older adults with osteoarthritis (OA).

METHOD

Participants were AA older adults aged 50 to 94 years with self-reported OA and chronic pain (N = 110). Cross-sectional data from the BPI-SF were obtained from all participants, and confirmatory factor analysis (CFA) was used to evaluate the factor structure. Measurement invariance across young-old (aged 50 to 69 years) and old-old (aged 70 to 94 years) participants was examined at configural, full metric, and full scalar levels.

RESULTS

CFA revealed that a three-factor model (i.e., pain intensity, activity interference, and affective interference) demonstrated the best fit (χ2/df = 1.595, comparative fit index [CFI] = 0.949, root-mean-square error of approximation = 0.074). The change of CFI between configural and metric invariance was below the cutoff point of 0.01, supporting full metric (i.e., factor loadings) invariance across the two age groups. However, full scalar (i.e., item intercepts) invariance was not demonstrated.

CONCLUSION

Results support a three-factor structure of the BPI-SF, which is consistent across two age groups for AA older adults with OA. This study provides evidence that the BPI-SF can reliably measure pain intensity and two distinct dimensions of pain interference in this population.

Prevalence of sleep disturbances in endometriosis patients: a systematic review and meta-analysis

Objective

This study systematically analyzes the prevalence of sleep disturbance in patients with endometriosis.

Methods

The PubMed, Web of Science, Embase, Wanfang, China National Knowledge Internet Database (CNKI), China Science and Technology Journal Database were searched from their establishment to January 2024, using the search terms endometriosis and sleep disturbance to collect relevant literature on the prevalence of sleep disturbance in patients with endometriosis. Two researchers independently screened the literature, extracted data, and evaluated the risk of bias. The prevalence of sleep disorders in patients with endometriosis was systematically analyzed using Stata17.0 software.

Results

Sixteen studies with 2573 participants were included. The prevalence of sleep disturbance in patients with endometriosis was 70.8% (95% confidence interval: 60.7%~80.9%). The said prevalence was higher in China than in Iran and the European countries (78.2 vs. 57.6 vs. 64.4, Q=9.27, P=0.010) and increased significantly since 2018 (79.0 vs. 61.3, Q=3.97, P=0.046). This prevalence was significantly higher in the cohort study than that in cross-sectional and case-control studies (84.0 vs. 74.0 vs. 59.5, Q=7.16, P=0.028).

Conclusion

The prevalence of sleep disturbance is high in patients with endometriosis, particularly in China and its prevalence has increased significantly in recent years. Appropriate interventions are recommended to effectively prevent or minimize sleep disturbances in patients with endometriosis.

Sleep disorders and hyperarousal among patients with endometriosis: A case-control survey study

BACKGROUND

Endometriosis has been associated with sleep disorders, and hyperarousal appears to be involved in their pathogenesis; however, the presence of hyperarousal in the endometriosis population was never investigated.

METHODS

We conducted a case-control survey study by sending a questionnaire to all endometriosis patients followed up at our Centers. Controls were recruited among the general population. The questionnaire included demographic information, symptoms and history of endometriosis, the Hyperarousal Scale (H-Scale), the Pittsburgh Sleep Quality Index (PSQI), and the Insomnia Severity Index (ISI).

RESULTS

A total of 847 women completed the questionnaires: 430 (50.8 %) had endometriosis, and 417 (49.2 %) were controls. Endometriosis was associated with higher H-scale score (OR 2.9, 95 % CI 2.4-3.8, p = 0.000), higher PSQI score (OR 4.3, 95 % CI 3.2-5.7, p = 0.000), and higher ISI score (OR 4.6, 95 % CI 3.5-6.1, p = 0.000) in multivariable ordinal logistic regressions analysis. With path analysis, hyperarousal (H-Scale) reported a partial mediating role in the association between endometriosis and sleep disorders. The mediation effect represented 22.3-27.8 % of the entire association between endometriosis and sleep disturbances.

CONCLUSION

Endometriosis patients complaining sleep disorders may benefit by investigating the presence of hyperarousal given cognitive behavioral therapy was reported effective in improving hyperarousal and associated sleep disorders.

Influence of App-Based Self-Management on the Quality of Life of Women With Endometriosis

INTRODUCTION

Endometriosis can significantly impair the quality of life of those affected. Multimodal self-help measures are recommended but are often difficult to access. Smartphone apps have been shown to improve the quality of life for other conditions with chronic pain. The aim of this study was to examine the impact of the Endo-App (Endo Health GmbH, Chemnitz, Germany) on both disease-related quality of life and symptoms of endometriosis affecting it.

METHODS

In the present randomized, controlled pilot study, the impact of utilizing the Endo-App on the quality of life among a sample of 122 women affected by endometriosis is assessed. To measure the changes over a 12-week period, the study incorporates the validated Endometriosis Health Profile (EHP-5 and EHP-30) questionnaire from Oxford University, among other assessment tools.

RESULTS

The use of the Endo-App leads to significant changes in the following areas after 12 weeks compared to the control group: pain disability, pain self-efficacy, fatigue, depressive symptoms, and Endometriosis Health Profile scores. The EHP-5 score from T0 to T12 is reduced by -16.76 (p-value of the Mann-Whitney U test (pU) = 0.008), and the EHP-30 score by -15.48 (pU = 0.004). The results remain significant in sensitivity analyses. The effect size of Cohen's d was in the medium range.

CONCLUSION

In summary, the Endo-App improves both physical and psychological symptoms and the patient's self-efficacy. The Endo-App contributes to improving endometriosis care in Germany and enables women suffering from endometriosis to significantly increase their quality of life.

The Burden of Pelvic Pain Associated With Endometriosis Among Women in Selected European Countries and the United States: A Restricted Systematic Review

OBJECTIVE

To evaluate the burden of endometriosis-associated pelvic pain (EAPP) on health-related quality of life (HRQoL) among women living in similar socio-economic conditions.

DATA SOURCES

Searches were performed in PubMed and Embase on September 26, 2022. The review was performed in conformity with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis protocol (PRISMA-P) and was registered on PROSPERO (ID: CRD42023370363).

METHODS OF STUDY SELECTION

Due to the high volume of eligible publications following initial review, inclusion criteria were restricted to studies undertaken in France, Germany, Italy, Spain, the United Kingdom, and the United States. This restriction was applied before screening as these countries have broad social and economic similarities, and previous studies in the literature suggest pain reporting and experience are influenced by numerous socio-cultural factors. Eligible studies were those published between 2013 and 2022 and include a sample size of ≥50 participants. The search strategy identified all relevant publications relating to the burden of illness due to EAPP. A variety of terms are used in the literature to describe pain associated with endometriosis, and this was considered in the design of the search strategy and screening procedure.

TABULATION, INTEGRATION, AND RESULTS

The database searches resulted in a total of 6139 records. After removal of duplicates, 3855 records were assessed further. A total of 27 publications were identified as eligible. Fourteen (52%) were from Italy, 5 (19%) were multinational studies, 4 (15%) were from the United States, 3 (11%) were from Spain, and 1 (4%) was from Germany. Most studies were cross-sectional (n = 15; 56%); 7 (26%) were case-control studies; 3 (11%) were cohort studies; and 2 (7%) were longitudinal studies. These publications collectively highlighted an association between EAPP and reduced HRQoL. Several studies showed that EAPP was associated with lower HRQoL when compared with endometriosis without pain and potentially with chronic pelvic pain caused by other conditions, although the evidence is limited in this case. Moreover, the studies reported detrimental effects on general HRQoL, mental health functioning, and sexual functioning, culminating in reduced work productivity and difficulties in performing everyday activities. The associations were generally similar across study populations, including adolescents, as well as younger and older women. Results were consistent across the range of different patient-reported outcome tools used to assess HRQoL.

CONCLUSION

The existing literature suggests that, among women in selected European countries and the United States, EAPP is associated with reduced HRQoL, including impaired mental and sexual functioning, as well as reduced work performance and productivity; each of which may contribute to the societal burden of endometriosis.

The impact of vitamin D treatment on pregnancy rate among endometriosis patients: a systematic review and meta-analysis

Background

Vitamin D supplementation is supposed to have an important role in the management of several endometriosis-related aspects, offering potential relief to affected individuals. Herein, the authors aim to evaluate the impact of vitamin D on pregnancy rates and clinical symptoms in women with endometriosis.

Methods

The authors extensively searched PubMed, Cochrane Library, EMBASE, Ovid MEDLINE, and CINAHL from their inception to 20 July 2023.

Results

Three randomized controlled trials involving 167 patients were included in this meta-analysis. The findings demonstrated that vitamin D supplementation exhibits efficacy in alleviating dysmenorrhea associated with endometriosis, as evidenced by a meta-analysis showing a significant reduction in dysmenorrhea (mean difference -1.41, 95% CI -2.61 to -0.22, P = 0.02). However, the impact on dyspareunia was inconclusive, with a non-significant mean difference of -0.2 (95% CI -1.62 to 1.22, P = 0.78). In contrast, dyschezia significantly decreased with vitamin D supplementation (mean difference -1.10, 95% CI -2.22 to 0.02, P = 0.05 However, the meta-analysis did not show a significant effect of vitamin D on chronic pelvic pain associated with endometriosis.

Conclusion

While antioxidant vitamin D supplementation demonstrates general effectiveness in alleviating endometriosis symptoms, such as dysmenorrhea, dyspareunia, and dyschezia, the existing literature lacks direct investigations into the specific impact of vitamin D on enhancing pregnancy rates among endometriosis patients. This observation prompts various hypotheses, suggesting that the positive effects of vitamin D supplementation on endometriosis-related symptoms may indirectly contribute to improved pregnancy outcomes and enhanced fertility.

A Systematic Review of the Psychosocial Impact of Endometriosis before and after Treatment

While endometriosis is a common gynecologic disease associated with infertility, the psychosocial impact of endometriosis has not been evaluated against various quality of life (QoL) instruments and compared with other chronic illnesses. We rigorously analyzed the psychosocial burden of endometriosis in adult women and compared standardized and validated QoL scores of women with and without endometriosis, before and following treatment, and against other chronic illnesses. We searched PubMed, PsychINFO Embase, and Cochrane Reviews and ClinicalTrials.gov from January 1990 to December 2022 for publications using a detailed list of search terms related to QoL, endometriosis, and questionnaires. Only English-language publications that evaluated the association between Endometriosis and QoL using standardized and validated questionnaires measured at baseline and following treatment were considered. Four reviewers first performed a title and abstract screening followed by full text-review to finalize included articles. QoL scores of women with endometriosis were measured at baseline and analyzed against women without endometriosis and women with endometriosis who had undergone treatment. Additionally, baseline endometriosis scores were assessed against the published QoL scores of populations with other chronic conditions. Assessment of risk of bias was performed in accordance with Cochrane and Newcastle-Ottawa Scale guidelines. A total of 30 articles were included in this review: 4 randomized trials and 26 observational studies. The diagnosis and experience of women with symptomatic endometriosis had an equal or worse QoL score than that of other chronic conditions including heart disease, diabetes, and breast cancer when compared using the 36-Item Short Form Survey and World Health Organization Quality of Life questionnaires. Evidence showed association between low QoL and infertility, sexual dysfunction, mental health struggles, physical pain, poor sleep and fatigue. QoL scores were lower at baseline compared to following treatment in the majority of these domains. Endometriosis is associated with significant psychosocial burden and impaired QoL scores across baseline measurements in comparison to controls and other chronic illnesses. Medical and surgical interventions significantly decreased experienced burdens and improved QoL of women with endometriosis.

Sleep disorders in patients with endometriosis; a cross-sectional study

BACKGROUND

Endometriosis affects 10-15% of women of reproductive age and is considered a critical gynecological problem. Endometriosis causes pain and infertility, both of which can impair the patient's quality of life. Sleep disorders account for the most bothersome presentation of impaired quality of life. This study investigated the frequency and severity of sleep disorders in women with endometriosis.

METHODS

In this analytical cross-sectional study, 665 women referred to three hospitals in Tehran, Rasool-e-Akram, Pars, and Nikan, were included (463 patients with endometriosis and 202 women without endometriosis). All of them were informed about the study design and the aim of the research, and then they were asked to sign the consent form and complete the Pittsburgh Sleep Quality Index (PSQI). After data gathering and entering, they were analyzed by SPSS version 22 and were considered significant with P < 0.05.

RESULTS

The study population's mean age was 35.4 ± 7.9 years. The mean global PSQI score in the case group (endometriosis patients) was higher than in the control group (non-endometriosis patients) (10.6 vs. 7.1; P < 0.001). Patients with dyspareunia, dysuria, pelvic pain, and dyschezia had a significantly higher PSQI score (P < 0.05).

CONCLUSION

According to the findings of the present study, the sleep quality in endometriosis patients is low, and there is a need to pay greater attention to these patients. This may result in some changes in the therapeutic strategies for this disease.

Connecting the dots: the role of fatigue in female infertility

Fatigue, an increasingly acknowledged symptom in various chronic diseases, has garnered heightened attention, during the medical era of bio-psycho-social model. Its persistence not only significantly compromises an individual's quality of life but also correlates with chronic organ damage. Surprisingly, the intricate relationship between fatigue and female reproductive health, specifically infertility, remains largely unexplored. Our exploration into the existing body of evidence establishes a compelling link between fatigue with uterine and ovarian diseases, as well as conditions associated with infertility, such as rheumatism. This observation suggests a potentially pivotal role of fatigue in influencing overall female fertility. Furthermore, we propose a hypothetical mechanism elucidating the impact of fatigue on infertility from multiple perspectives, postulating that neuroendocrine, neurotransmitter, inflammatory immune, and mitochondrial dysfunction resulting from fatigue and its co-factors may further contribute to endocrine disorders, menstrual irregularities, and sexual dysfunction, ultimately leading to infertility. In addition to providing this comprehensive theoretical framework, we summarize anti-fatigue strategies and accentuate current knowledge gaps. By doing so, our aim is to offer novel insights, stimulate further research, and advance our understanding of the crucial interplay between fatigue and female reproductive health.

Endometriosis and mental health disorders: identification and treatment as part of a multimodal approach

Endometriosis is a disease marked by more than just pain and infertility, as it transcends the well-characterized physical symptoms to be frequently associated with mental health issues. This review focuses on the associations between endometriosis and anxiety, depression, sexual dysfunction, and eating disorders, all of which show a higher prevalence in women with the disease. Studies show that pain, especially the chronic pelvic pain of endometriosis, likely serves as a mediating factor. Recent studies evaluating genetic predispositions for endometriosis and mental health disorders suggest a shared genetic predisposition. Healthcare providers who treat women with endometriosis should be aware of these associations to best treat their patients. A holistic approach to care by gynecologists as well as mental health professionals should emphasize prompt diagnosis, targeted medical interventions, and psychological support, while also recognizing the role of supportive relationships in improving the patient's quality of life.

Fear of progression, depression, and sleep difficulties in people experiencing endometriosis-pain: A cross-sectional study

OBJECTIVE

Endometriosis is a chronic condition generally characterised by severe pain. Recent findings demonstrate disproportionately elevated rates of insomnia and fatigue among people with endometriosis, particularly among those with associated pain. Yet there is little understanding of the psychological factors that might contribute to these sleep and fatigue related difficulties. We investigated whether fear of progression and depression interacted with pain to influence fatigue and insomnia among people with endometriosis-related pain.

METHODS

A total of 206 individuals with endometriosis were included in this cross-sectional, online survey in January 2022. Participants provided relevant demographics and endometriosis characteristics. The BPI-SF, FoP-Q-SF, DASS-21, CFS and ISI were used to assess pain intensity, fear of progression, depression, fatigue, and insomnia symptoms, respectively. Associations between key variables were assessed with correlations. A path analysis determined whether the relationships between pain and fatigue, and pain and insomnia, depended on levels of fear of progression and depression.

RESULTS

Controlling for age, fear of progression was uniquely associated with worse fatigue (β = 0.348, p < .001) and insomnia (β = 0.389, p < .001), and moderated the relationship between pain and fatigue (β = 0.155, p = .009). Specifically, with increasing pain severity, the effects of fear of progression on fatigue were exacerbated. Depression was uniquely associated with fatigue (β = 0.360, p < .001), but did not elicit any moderation effects.

CONCLUSION

These results highlight the role of fear of progression and depression in endometriosis-related fatigue and insomnia, paving the way for future interventions targeting these constructs to be tested.

The relationship between sleep disturbances and endometriosis: A systematic review

OBJECTIVE

Endometriosis is associated with a range of symptoms that can negatively impact a person's quality of life. While pain and infertility have received at lot of attention, sleep disturbances in individuals with endometriosis has been overlooked in both clinical practice and research. Therefore, the primary aim of this systematic review was to gather evidence from the current literature to illustrate the association between sleep disturbances and endometriosis.

STUDY DESIGN

A literature search was conducted using three electronic databases (OVID EMBASE, MEDLINE, and Web of Science). Observational studies, published in English, that involved participants aged 18 years or older that compared sleep outcomes between endometriosis patients and those without a history of endometriosis were included. The quality of each study was assessed using the Joanna Briggs Institute critical appraisal tools.

RESULTS

Nine studies (six case-control and three cross-sectional) were included in this review; 7 with low risk of bias and 2 with moderate risk of bias. The studies demonstrated heterogeneity in the assessment of sleep disturbances. However, 7 studies reported a significant positive association between endometriosis and sleep disturbances. Moreover, this impact on sleep was further complicated by the complex interaction between pain, fatigue and quality of life.

CONCLUSION

Current studies suggest an association between sleep disturbances and endometriosis, which may provide a blueprint for future clinical recommendations to screen and treat sleep disturbances in individuals with endometriosis to improve their quality of life. Future studies should aim to standardise the methods of assessing sleep disturbances and explore potential contributing factors.

Associations between endometriosis and common symptoms: findings from the Australian Longitudinal Study on Women's Health

BACKGROUND

Endometriosis has been linked to higher rates of a variety of symptoms; however, the findings from longitudinal studies are scarce and inconsistent.

OBJECTIVE

This study aimed to examine the association between endometriosis and common symptoms in a prospective cohort study.

STUDY DESIGN

This study included 7606 women born from 1973 to 1978 using data from the Australian Longitudinal Study on Women's Health that were collected every 3 years from 2009 to 2018. We identified women with endometriosis based on self-reported incidence from each survey and linked administrative health data. At each survey, women also completed a checklist on the presence of 24 symptoms. Generalized estimating equations for multinomial responses were used for analyses.

RESULTS

Women with endometriosis had significantly more menstrual symptoms than those without endometriosis with an adjusted odds ratio (95% confidence interval) of 3.61 (3.11-4.19) for severe period pain, 2.40 (2.10-2.74) for heavy menstrual bleeding, 1.76 (1.52-2.03) for irregular bleeding, and 1.52 (1.32-1.76) for premenstrual tension. They also had higher odds of mental health problems with adjusted odds ratios of 1.67 (1.39-2.01) for depression and 1.59 (1.24-2.03) for anxiety and higher odds of allergies and nonspecific symptoms with adjusted odds of 1.62 (1.40-1.89) for allergies or hay fever or sinusitis, 1.79 (1.56-2.05) for severe tiredness, 1.56 (1.35-1.81) for sleep difficulty, and 1.77 (1.37-2.18) for palpitations. There was also a strong association with other forms of pain with an adjusted odds ratio of 1.76 (1.53-2.04) for backpain, 1.50 (1.29-1.74) for headaches or migraines, and 1.65 (1.41-1.93) for stiff or painful joints. Women with endometriosis also had increased odds of developing bowel and urinary symptoms with an adjusted odds ratio (95% confidence interval) of 1.67 (1.35-2.08) for constipation, 1.46 (1.12-1.90) for hemorrhoids or piles, 1.25 (1.03-1.52) for indigestion or heartburn, 2.80 (1.71-4.58) for urine burn or stings, and 1.37 (1.03-1.82) for vaginal discharge or irritation. The association between each symptom and endometriosis was similar whether endometriosis was surgically confirmed or clinically suspected. No association was found between endometriosis and the risk for skin problems, leaking urine, or breathing difficulty.

CONCLUSION

This study suggests that women with endometriosis are more likely to report not only menstrual symptoms but are also at an increased risk for mental health problems, other pain symptoms, bowel and urinary symptoms, and nonspecific symptoms, such as severe tiredness and difficulty sleeping.

Association Between Pharmacotherapy and Sleep Quality in Patients with Chronic Orofacial and Chronic Body Pain: A Cross-Sectional Study

Purpose

Sleep impairment is associated with many chronic pain disorders. While there is an association between chronic pain and sleep disturbances, little is known about the influence of pharmacotherapy for chronic pain conditions, particularly chronic opioid therapy, on sleep. This study aimed to 1) compare the sleep quality (SQ) in patients with two different pain conditions-chronic body pain and chronic orofacial pain; 2) assess the correlation of SQ and pain intensity; and 3) evaluate the association between pharmacotherapy and SQ.

Patients and Methods

The Pittsburgh Sleep Quality Index (PSQI) was used to measure the SQ in subjects with 1) chronic body pain (n = 100) and 2) chronic orofacial pain (n = 100). The visual analogue scale was applied for pain intensity rating. All subjects were adults recruited at Massachusetts General Hospital, United States. The subjects' demographic data, pain intensity, diagnosis and concurrent use of medications were extracted from their electronic medical records (EMR). Statistical analyses were performed using T-test and Pearson correlation coefficient.

Results

Among 200 subjects (mean age 51.01 ± 15.52 years), 141 (70.5%) were females. PSQI and pain intensity were statistically significantly different between the two groups (p < 0.05 and p < 0.0001, respectively) and higher in subjects with chronic body pain. There was a positive correlation between PSQI and pain intensity (chronic orofacial pain r = 0.3535, p = 0.0004; chronic body pain: r = 0.2247, p < 0.026). PSQI was higher in chronic orofacial pain subjects utilizing opioids and benzodiazepines (PSQI = 15.25).

Conclusion

Chronic pain impairs SQ, which is noticeably worse in subjects with body pain conditions. In addition, pain intensity was correlated with poorer SQ, which in turn was linked to the concomitant use of opioid and benzodiazepine therapy in chronic orofacial pain.

The impact of endometriosis on depressive and anxiety symptoms and quality of life: a systematic review

Introduction

Endometriosis is a common gynecological disorder affecting approximately 10-15% of women of reproductive age. The main complaints of patients with endometriosis are pain and fertility problems. Symptoms of endometriosis can impact the psychological functioning of the patients and significantly compromise their mental health.

Methods

The aim of this review was to assess the prevalence of depressive and anxiety symptoms and quality of life in endometriosis patients. For this systematic review, we searched the PubMed, MEDLINE, ProQuest, EMBASE, Cochrane, CINAHL, Google Scholar, Scopus, and ScienceDirect electronic databases up to March 2023 to identify potentially relevant studies. The systematic review in the present paper is reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidance.

Results

Of four records identified, 18 were eligible to be reviewed on the association between endometriosis and symptoms of depression and anxiety. Of 8,901 records identified, 28 were reviewed on the association between endometriosis and quality of life. The reviewed articles showed a prevalence ranging from 9.8 to 98.5% for depressive symptoms and 11.5 to 87.5% for anxiety. The quality of life in patients with endometriosis was significantly impaired, regardless of the tool used for evaluation.

Discussion

This systematic review shows that endometriosis is associated with depressive and anxiety symptoms and impaired HRQoL. Broad correlating factors modulate mental health outcomes, indicating the complex relationship between the disease and the psychological health of the patients.

Impact of endometriosis on women's health-related quality of life: A national prospective cohort study

OBJECTIVE

To examine the association between endometriosis and women's health-related quality of life (HRQoL).

STUDY DESIGN

This study included 3728 women born in 1973-78 using data from the Australian Longitudinal Study on Women's Health. Women with endometriosis were identified using self-reported longitudinal surveys linked to administrative health records. A mixed effect model with only random intercept and generalised estimating equations with binary logistic regressions were used to examine the association between endometriosis and health-related quality of life over eight time points. Each HRQoL scale was analysed in terms of binary outcomes by comparing women who had a lower HRQoL (scoring below the 25th percentile) with those who had a higher HRQoL (scoring above the 25th percentile).

MAIN OUTCOME MEASURES

Women's HRQoL was assessed using the 36-item Short Form Survey every 3 years from 1996 to 2018.

RESULTS

Endometriosis was associated with significantly worse reports of HRQoL over time. In the comparison against women without endometriosis, the following adjusted odds ratios (95 % confidence intervals) were calculated for women with endometriosis having worse scores on the eight domains of the Short Form Survey: physical functioning 1.33 (1.19, 1.50), role physical 1.57 (1.41, 1.74), bodily pain 1.65 (1.48, 1.82), general health 1.61 (1.42, 1.81), vitality 1.38 (1.23, 1.55), social functioning 1.38 (1.25, 1.53), role emotion 1.19 (1.06, 1.33), mental health 1.32 (1.18, 1.48). Women with endometriosis also had significantly lower physical health 1.68 (1.51, 1.88) and mental health components scores 1.28 (1.14, 1.44).

CONCLUSIONS

Endometriosis is associated with worse physical, mental, and social functioning and well-being. Bodily pain was the most affected HRQoL domain.

Women's quality of sleep and in vitro fertilization success

Women undergoing in vitro fertilization (IVF) are emotionally challenged. Anxiety, depression, and sleep disturbances are common complaints. The impact of these symptoms on IVF outcome is however debated. In this study, we aimed at investigating whether sleep quality and psychological health can affect the chances of success of the procedure. Women undergoing IVF were recruited at the time of oocytes retrieval. Women's sleep quality and psychological health was assessed using the Pittsburgh Sleep Quality Index (PSQI), the Fertility Problem Inventory (FPI), and the Hospital Anxiety and Depression Scale (HADS). Baseline characteristics and results of the three scales were compared between women who did and did not succeed. Overall, 263 women were included, of whom 81 had a clinical pregnancy (31%). As expected, successful women were younger, and their ovarian reserve was more preserved. FPI and HADS scores did not differ. Conversely, a statistically significant difference emerged for the PSQI score, the median [interquartile range] in pregnant and non-pregnant women being 4 [3-5] and 5 [3-7], respectively (p = 0.004). The crude and adjusted OR of pregnancy in women with a PSQI > 5 (indicating impaired sleep quality) was 0.46 (95% CI 0.25-0.86, p = 0.02) and 0.50 (95% CI: 0.26-0.94, p = 0.03), respectively. In conclusion, low sleep quality is common in women scheduled for IVF and could influence the success of the procedure.

Activation of α7 nicotinic acetylcholine receptor retards the development of endometriosis

BACKGROUND

Women with endometriosis have been shown to have a reduced vagal tone as compared with controls and vagotomy promoted while vagus nerve stimulation (VNS) decelerated the progression of endometriosis in mice. Extensive research also has shown that the activation of the cholinergic anti-inflammatory pathway by VNS activates α7 nicotinic acetylcholine receptor (α7nAChR), potently reducing inflammation. Yet whether α7nAChR plays any role in endometriosis is unknown. We evaluated its expression in normal endometrium, ovarian and deep endometriotic lesions, and evaluated its role in the development of endometriosis.

METHODS

Immunohistochemistry analyses of α7nAChR in endometriotic lesions as well as control endometrium, and quantification of tissue fibrosis by Masson trichrome staining were performed. Mouse experiments were conducted to evaluate the impact of α7nAChR activation or suppression on lesional progression and possible therapeutic effect. Finally, in vitro experiments were conducted to evaluate the effect of activation of α7nAChR on epithelial-mesenchymal transition (EMT), fibroblast-to-myofibroblast transdifferentiation (FMT), smooth muscle metaplasia (SMM) and fibrogenesis in an endometriotic epithelial cell line and primary endometriotic stromal cells derived from ovarian endometrioma tissue samples.

RESULTS

Immunostaining of α7nAChR was significantly reduced in human endometriotic epithelial cells as compared with their counterpart in normal endometrium. Lesional α7nAChR staining levels correlated negatively with lesional fibrosis and the severity of dysmenorrhea. The α7nAChR agonist significantly impeded the development of endometriotic lesions in mouse models possibly through hindrance of EMT and FMT. It also demonstrated therapeutic effects in mice with induced deep endometriosis. Treatment of endometriotic epithelial and stromal cells with an α7nAChR agonist significantly abrogated platelet-induced EMT, FMT and SMM, and suppressed cellular contractility and collagen production.

CONCLUSIONS

α7nAChR is suppressed in endometriotic lesions, and its activation by pharmacological means can impede EMT, FMT, SMM, and fibrogenesis of endometriotic lesions. As such, α7nAChR can be rightfully viewed as a potential target for therapeutic invention.
