Chronic Fatigue, Physical Impairments and Quality of Life in Women with Endometriosis: A Case-Control Study

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.

The Benefits of an Integral HAMMAM Experience Combining Hydrotherapy and Swedish Massage on Pain, Subjective Well-Being and Quality of Life in Women with Endometriosis-Related Chronic Pelvic Pain: A Randomized Controlled Trial

Background and Objectives: To evaluate the effectiveness of an integral HAMMAM experience, a 4-week therapeutic program that combined hydrotherapy and Swedish massage, applied in a multisensorial immersive environment, on pain, well-being and quality of life (QoL) in women with endometriosis-related chronic pelvic pain that is unresponsive to conventional treatment. Materials and Methods: This randomized controlled trial included 44 women with endometriosis. They were randomly allocated to either the 'HAMMAM' group (n = 21) or to a control group (n = 23). The primary outcome, pain intensity, was evaluated using numeric rating scales (NRSs). The secondary outcomes were pain interference, pain-related catastrophic thoughts, pressure pain thresholds (PPTs), subjective well-being, functional capacity and QoL, which were evaluated using the brief pain inventory (BPI), the pain catastrophizing scale (PCS), algometry, the subjective well-being scale-20 (EBS-20), the Patient-Reported Outcomes Measurement Information System-29 (PROMIS-29) and the Endometriosis Health Profile-30 Questionnaire (EHP-30), respectively. The primary and secondary outcomes were measured at the baseline and after the intervention. The statistical (between-group analyses of covariance) and clinical effects were analyzed by the intention to treat. Results: The adherence rate was 100.0% and the mean (± standard deviation) satisfaction was 9.71 ± 0.46 out of 10. No remarkable health problems were reported during the trial. The 'HAMMAM' intervention improved dysmenorrhea and dyspareunia after the intervention with large and moderate effect sizes, respectively. Improvements in pain interference during sleep and PPTs in the pelvic region were also observed in women allocated to the 'HAMMAM' group. No effects were observed in catastrophizing thoughts, well-being nor QoL, except for the sleep subscale. Conclusions: A 4-week program of an integral 'HAMMAM' experience combining hydrotherapy and massage in a multisensorial immersive environment is a feasible and effective intervention to alleviate pain during menstruation and sexual intercourse as well as pain interference with sleep in women with endometriosis.

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.

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.

A COM-B and Theoretical Domains Framework Mapping of the Barriers and Facilitators to Effective Communication and Help-Seeking Among People With, or Seeking a Diagnosis Of, Endometriosis

Endometriosis is a chronic condition in which tissue resembling the endometrium grows outside the womb, causing severe chronic pain. People with endometriosis report difficulty in help-seeking and communicating with healthcare professionals, contributing to diagnosis delays and ineffective management. The present study aimed to identify barriers and facilitators to effective communication using the Theoretical Domains Framework (TDF) and COM-B model to inform behavior change intervention development. This study was a qualitative semi-structured interview and open-ended survey design. Thematic Analysis was utilized to identify barriers and facilitators to effective communication which were mapped to the TDF and COM-B model. Four women aged 25 to 44 with a formal diagnosis of endometriosis participated in interviews. Thirty-three participants, aged 20-48 years, participated in the online survey, 21 of whom had a diagnosis of endometriosis (12 were currently seeking diagnosis). Five COM-B domains were identified: reflective motivation, social and physical opportunity, physical and psychological capability. Ten TDF domains were reflected in concerns surrounding dismissal, disempowerment, social norms, beliefs about consequences, cognitive resources, reinforcement, and environmental context and resources, among others. This is the first study to identify barriers and facilitators of effective communication and help-seeking in light of established behavioral change theory and frameworks for comprehensive intervention design. This provides a comprehensive explanation of challenges in help-seeking for endometriosis and represents the first step in the development of complex interventions to improve help-seeking and communication for people with endometriosis. Interventions targeting salient barriers will have greater potential to change behavior and improve outcomes.

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.

Assessment of a Digital Symptom Checker Tool's Accuracy in Suggesting Reproductive Health Conditions: Clinical Vignettes Study

BACKGROUND

Reproductive health conditions such as endometriosis, uterine fibroids, and polycystic ovary syndrome (PCOS) affect a large proportion of women and people who menstruate worldwide. Prevalence estimates for these conditions range from 5% to 40% of women of reproductive age. Long diagnostic delays, up to 12 years, are common and contribute to health complications and increased health care costs. Symptom checker apps provide users with information and tools to better understand their symptoms and thus have the potential to reduce the time to diagnosis for reproductive health conditions.

OBJECTIVE

This study aimed to evaluate the agreement between clinicians and 3 symptom checkers (developed by Flo Health UK Limited) in assessing symptoms of endometriosis, uterine fibroids, and PCOS using vignettes. We also aimed to present a robust example of vignette case creation, review, and classification in the context of predeployment testing and validation of digital health symptom checker tools.

METHODS

Independent general practitioners were recruited to create clinical case vignettes of simulated users for the purpose of testing each condition symptom checker; vignettes created for each condition contained a mixture of condition-positive and condition-negative outcomes. A second panel of general practitioners then reviewed, approved, and modified (if necessary) each vignette. A third group of general practitioners reviewed each vignette case and designated a final classification. Vignettes were then entered into the symptom checkers by a fourth, different group of general practitioners. The outcomes of each symptom checker were then compared with the final classification of each vignette to produce accuracy metrics including percent agreement, sensitivity, specificity, positive predictive value, and negative predictive value.

RESULTS

A total of 24 cases were created per condition. Overall, exact matches between the vignette general practitioner classification and the symptom checker outcome were 83% (n=20) for endometriosis, 83% (n=20) for uterine fibroids, and 88% (n=21) for PCOS. For each symptom checker, sensitivity was reported as 81.8% for endometriosis, 84.6% for uterine fibroids, and 100% for PCOS; specificity was reported as 84.6% for endometriosis, 81.8% for uterine fibroids, and 75% for PCOS; positive predictive value was reported as 81.8% for endometriosis, 84.6% for uterine fibroids, 80% for PCOS; and negative predictive value was reported as 84.6% for endometriosis, 81.8% for uterine fibroids, and 100% for PCOS.

CONCLUSIONS

The single-condition symptom checkers have high levels of agreement with general practitioner classification for endometriosis, uterine fibroids, and PCOS. Given long delays in diagnosis for many reproductive health conditions, which lead to increased medical costs and potential health complications for individuals and health care providers, innovative health apps and symptom checkers hold the potential to improve care pathways.

Effect of a Multimodal Supervised Therapeutic Exercise Program on Quality of Life, Pain, and Lumbopelvic Impairments in Women With Endometriosis Unresponsive to Conventional Therapy: A Randomized Controlled Trial

OBJECTIVE

To evaluate the effectiveness of "Physio-EndEA", a multimodal nine-week supervised exercise intervention, on quality of life, pain, and lumbopelvic impairments in women with endometriosis unresponsive to conventional therapy.

DESIGN

Parallel-group randomized controlled trial. Outcomes were measured at baseline, post-intervention, and at 1 year.

SETTING

Two Public University Hospitals.

PARTICIPANTS

This trial included 31 women with endometriosis (N=31) randomly allocated to "Physio-EndEA" group (n=16) or control group (n=15). Four participants dropped out of the study for causes unrelated to the intervention.

INTERVENTIONS

The "Physio-EndEA" program consisted of a 1-week lumbopelvic stabilization learning phase followed by an 8-week phase of stretching, aerobic, and resistance exercises focused on the lumbopelvic area. It was sequentially instructed and supervised by a trained physiotherapist (with volume and intensity progression) and adapted daily to the potential of each participant. Control group received the usual treatment stipulated by their gynecologist.

MAIN OUTCOME MEASURES

The primary outcome was quality of life. Secondary outcomes were pain intensity, pressure pain thresholds, pain-related catastrophic thoughts, abdominal and back strength, lumbopelvic stability, and muscle architecture.

RESULTS

Adherence rate was 90.6% and mean (±standard deviation) satisfaction was 9.44±0.73 out of 10. No remarkable health problems were reported during the trial. In comparison with controls, the quality of life was improved post-intervention and at 1 year in the Physio-EndEA group with large effect sizes (d>0.80). This group also evidenced: a reduced intensity of dyspareunia, catastrophic thoughts; an increase in pelvic, lumbar, and distal pressure pain thresholds; increases in abdominal and back strength and lumbopelvic stability; and increased thickness of transversus abdominis (right side) and width of lumbar multifidus (left side).

CONCLUSION

A 9-week program of multimodal supervised therapeutic exercise is a feasible and effective intervention to improve QoL in women with endometriosis. This program also offers benefits in terms of pain/sensitization and lumbopelvic impairments.

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.

The impact of endometriosis on work ability in young Australian women

BACKGROUND

Whereas symptomatic endometriosis may affect work performance, the impact of endometriosis in the general community is not known.

AIMS

The associations between endometriosis and each of sick leave and work ability, were investigated in a large sample of non-healthcare seeking women.

MATERIALS AND METHODS

This community-based, cross-sectional study recruited 6986 women, aged 18-39 years, from three eastern states of Australia between 11 November 2016 and 21 July 2017. Women were identified as having endometriosis if they had undergone a pelvic ultrasound and reported a diagnosis of endometriosis. Working women completed the Work Ability Index.

RESULTS

Participants were predominantly of European ancestry (73.1%) and 46.8% were overweight or had obesity. The prevalence of endometriosis was 5.4% (95%CI 4.9-6.0%) with the highest prevalence of 7.7% (95%CI 6.5 to 9.1%) for women aged 35-39 years. Among the 4618 working women, those with endometriosis had significantly more sick days from work (33.6% reported ≥10 days vs 13.5%, overall χ2 P < 0.001). Endometriosis was associated with a greater likelihood of poor to moderate work ability, after adjusting for age, body mass index, ethnicity, relationship status, student status, insecure housing, being a carer for another person, parity, ever use of assisted reproductive technologies, and depressed mood (odds ratio 1.90, 95%CI 1.40-2.58, P < 0.001).

CONCLUSIONS

This study provides new evidence that the negative impact of endometriosis on work attendance and work ability is not limited to women with prevalent symptoms and severe disease, but appears to encompass women across a broader spectrum of this condition in the community.

Identification of early symptoms of endometriosis through the analysis of online social networks: A social media study

Objective

Endometriosis is a complex full-body inflammation disease with an average time to diagnosis of 7-10 years. Social networks give opportunity to patient to openly discuss about their condition, share experiences, and seek advice. Thus, data from social media may provide insightful data about patient's experience. This study aimed at applying a text-mining approach to online social networks in order to identify early signs associated with endometriosis.

Methods

An automated exploration technique of online forums was performed to extract posts. After a cleaning step of the built corpus, we retrieved all symptoms evoked by women, and connected them to the MedDRA dictionary. Then, temporal markers allowed targeting only the earliest symptoms. The latter were those evoked near a marker of precocity. A co-occurrence approach was further applied to better account for the context of evocations.

Results

Results were visualised using the graph-oriented database Neo4j. We collected 7148 discussions threads and 78,905 posts from 10 French forums. We extracted 41 groups of contextualised symptoms, including 20 groups of early symptoms associated with endometriosis. Among these groups of early symptoms, 13 were found to portray already known signs of endometriosis. The remaining 7 clusters of early symptoms were limb oedema, muscle pain, neuralgia, haematuria, vaginal itching, altered general condition (i.e. dizziness, fatigue, nausea) and hot flush.

Conclusion

We pointed out some additional symptoms of endometriosis qualified as early symptoms, which can serve as a screening tool for prevention and/or treatment purpose. The present findings offer an opportunity for further exploration of early biological processes triggering this disease.

Economic Implications of Endometriosis: A Review

Endometriosis is a chronic inflammatory disease that can have serious physical and emotional consequences for patients in terms of pain, quality of life, and infertility. Despite affecting about 10% of women, the pathophysiology and economic impact of the disease are not fully understood. This study aimed to review and summarize research articles quantifying the direct and indirect costs of endometriosis in the context of current national and international treatment guidelines. A search including the terms 'endometriosis' AND 'costs' OR 'cost of illness' OR 'cost analysis' OR 'economic burden' was performed, focusing on studies published between January 2000 and May 2022. Total costs, costs of primary and secondary care, productivity losses, and indirect costs were reported. The medical costs of endometriosis were principally registered in secondary care settings, where surgery was the main cost driver. There was considerable variability of populations and study settings, with the overall direct medical cost range of endometriosis from US$1459 to US$20,239 (2022) per patient per year. An increasing trend has been reported in secondary care costs over time; however, not enough data were available at this time to evaluate inpatient and outpatient costs versus treatment strategies. Similarly, further research is required to evaluate the costs and potential savings associated with new therapies. Numerous studies have evaluated the indirect costs of endometriosis in recent years, finding costs between US$4572 and US$14,079 (2022). Currently, limited data are available on the economic burden of the disease at the patient level.

Hormonal treatments for endometriosis: The endocrine background

Endometriosis is a benign uterine disorder characterized by menstrual pain and infertility, deeply affecting women's health. It is a chronic disease and requires a long term management. Hormonal drugs are currently the most used for the medical treatment and are based on the endocrine pathogenetic aspects. Estrogen-dependency and progesterone-resistance are the key events which cause the ectopic implantation of endometrial cells, decreasing apoptosis and increasing oxidative stress, inflammation and neuroangiogenesis. Endometriotic cells express AMH, TGF-related growth factors (inhibin, activin, follistatin) CRH and stress related peptides. Endocrine and inflammatory changes explain pain and infertility, and the systemic comorbidities described in these patients, such as autoimmune (thyroiditis, arthritis, allergies), inflammatory (gastrointestinal/urinary diseases) and mental health disorders.The hormonal treatment of endometriosis aims to block of menstruation through an inhibition of hypothalamus-pituitary-ovary axis or by causing a pseudodecidualization with consequent amenorrhea, impairing the progression of endometriotic implants. GnRH agonists and antagonists are effective on endometriosis by acting on pituitary-ovarian function. Progestins are mostly used for long term treatments (dienogest, NETA, MPA) and act on multiple sites of action. Combined oral contraceptives are also used for reducing endometriosis symptoms by inhibiting ovarian function. Clinical trials are currently going on selective progesterone receptor modulators, selective estrogen receptor modulators and aromatase inhibitors. Nowadays, all these hormonal drugs are considered the first-line treatment for women with endometriosis to improve their symptoms, to postpone surgery or to prevent post-surgical disease recurrence. This review aims to provide a comprehensive state-of-the-art on the current and future hormonal treatments for endometriosis, exploring the endocrine background of the disease.

'Physio-EndEA' Study: A Randomized, Parallel-Group Controlled Trial to Evaluate the Effect of a Supervised and Adapted Therapeutic Exercise Program to Improve Quality of Life in Symptomatic Women Diagnosed with Endometriosis

Aim: The ‘Physio-EndEA’ study aims to explore the potential benefits of a therapeutic exercise program (focused on lumbopelvic stabilization and tolerance to exertion) on the health-related quality of life (HRQoL) of symptomatic endometriosis women. Design: The present study will use a parallel-group randomized controlled trial design. Methods: A total of 22 symptomatic endometriosis women will be randomized 1:1 to the Physio-EndEA or usual care groups. The ‘Physio-EndEA’ program will consist of a one-week lumbopelvic stabilization learning phase followed by an eight-week phase of stretching, aerobic and resistance exercises focused on the lumbopelvic area that will be sequentially instructed and supervised by a trained physiotherapist (with volume and intensity progression) and adapted daily to the potential of each participant. The primary outcome measure is HRQoL. The secondary outcome measures included clinician-reported outcomes (pressure pain thresholds, muscle thickness and strength, flexibility, body balance and cardiorespiratory fitness) and patient-reported outcomes (pain intensity, physical fitness, chronic fatigue, sexual function, gastrointestinal function and sleep quality). Discussion: Findings of this study will help to identify cost-effective non-pharmacological options (such as this exercise-based intervention) that may contribute to the improvement of HRQoL in symptomatic endometriosis women.

Menstrual cycle-associated symptoms and workplace productivity in US employees: A cross-sectional survey of users of the Flo mobile phone app

Objective

Mood and physical symptoms related to the menstrual cycle affect women's productivity at work, often leading to absenteeism. However, employer-led initiatives to tackle these issues are lacking. Digital health interventions focused on women's health (such as the Flo app) could help fill this gap.

Methods

1867 users of the Flo app participated in a survey exploring the impact of their menstrual cycle on their workplace productivity and the role of Flo in mitigating some of the identified issues.

Results

The majority reported a moderate to severe impact of their cycle on workplace productivity, with 45.2% reporting absenteeism (5.8 days on average in the previous 12 months). 48.4% reported not receiving any support from their manager and 94.6% said they were not provided with any specific benefit for issues related to their menstrual cycle, with 75.6% declaring wanting them. Users stated that the Flo app helped them with the management of menstrual cycle symptoms (68.7%), preparedness and bodily awareness (88.7%), openness with others (52.5%), and feeling supported (77.6%). Users who reported the most positive impact of the Flo app were 18-25% less likely to report an impact of their menstrual cycle on their productivity and 12-18% less likely to take days off work for issues related to their cycle.

Conclusions

Apps such as Flo could equip individuals with tools to better cope with issues related to their menstrual cycle and facilitate discussions around menstrual health in the workplace.

Lifestyle and Chronic Pain in the Pelvis: State of the Art and Future Directions

During their lifespan, many women are exposed to pain in the pelvis in relation to menstruation and pregnancy. Such pelvic pain is often considered normal and inherently linked to being a woman, which in turn leads to insufficiently offered treatment for treatable aspects related to their pain experience. Nonetheless, severe dysmenorrhea (pain during menstruation) as seen in endometriosis and pregnancy-related pelvic girdle pain, have a high impact on daily activities, school attendance and work ability. In the context of any type of chronic pain, accumulating evidence shows that an unhealthy lifestyle is associated with pain development and pain severity. Furthermore, unhealthy lifestyle habits are a suggested perpetuating factor of chronic pain. This is of specific relevance during lifespan, since a low physical activity level, poor sleep, or periods of (di)stress are all common in challenging periods of women’s lives (e.g., during menstruation, during pregnancy, in the postpartum period). This state-of-the-art paper aims to review the role of lifestyle factors on pain in the pelvis, and the added value of a lifestyle intervention on pain in women with pelvic pain. Based on the current evidence, the benefits of physical activity and exercise for women with pain in the pelvis are supported to some extent. The available evidence on lifestyle factors such as sleep, (di)stress, diet, and tobacco/alcohol use is, however, inconclusive. Very few studies are available, and the studies which are available are of general low quality. Since the role of lifestyle on the development and maintenance of pain in the pelvis, and the value of lifestyle interventions for women with pain in the pelvis are currently poorly studied, a research agenda is presented. There are a number of rationales to study the effect of promoting a healthy lifestyle (early) in a woman’s life with regard to the prevention and management of pain in the pelvis. Indeed, lifestyle interventions might have, amongst others, anti-inflammatory, stress-reducing and/or sleep-improving effects, which might positively affect the experience of pain. Research to disentangle the relationship between lifestyle factors, such as physical activity level, sleep, diet, smoking, and psychological distress, and the experience of pain in the pelvis is, therefore, needed. Studies which address the development of management strategies for adapting lifestyles that are specifically tailored to women with pain in the pelvis, and as such take hormonal status, life events and context, into account, are required. Towards clinicians, we suggest making use of the window of opportunity to prevent a potential transition from localized or periodic pain in the pelvis (e.g., dysmenorrhea or pain during pregnancy and after delivery) towards persistent chronic pain, by promoting a healthy lifestyle and applying appropriate pain management.

Patient-Reported Outcome Measures in Endometriosis

Patient Reported Outcome Measures (PROM) evoke measurements that allow capturing patients’ perspectives on their condition. In endometriosis care, physicians’ understanding of the effect of the disease and the treatment on patients is often poor. The use of PROMs in endometriosis clinical practice can facilitate patient-provider communication and the implementation of patient-centered care, improve patients’ quality of life, as well as provide a tool for patients’ self-management of the disease. Today, PROMs are extensively used in research and clinical trials, however they are barely used in clinical practice. The development of digital tools facilitating capturing PROMs can contribute to their use by physicians in routine endometriosis care. However, all PROMs are not adapted to be used in routine care in the context of endometriosis. The objective of this study was to present a catalogue of available PROMs for routine endometriosis care and evaluate them according to selected criteria. To do so, we explored the different PROMs currently in the literature. Consequently, 48 PROM were identified as tools used to evaluate various dimensions of the impact of endometriosis on patients. The selected PROMs were evaluated for their potential to be used as a standard in clinical practice in endometriosis. The selected catalogue of PROMs is the starting point for the integration of digital tools to capture PROMs and the development of patient-centered dashboards to be used by patients and clinicians in endometriosis care and self-management to improve care processes, patient satisfaction, quality of life, and outcomes.

Blood Work: Managing Menstruation, Menopause and Gynaecological Health Conditions in the Workplace

The menstrual cycle remains neglected in explorations of public health, and entirely remiss in occupational health literature, despite being a problematic source of gendered inequalities at work. This paper proposes the new concept of blood work to explain the relationship between menstruation (and associated gynaecological health conditions) and employment for women and trans/non-binary people. We build on and extend health and organisational literature on managing bodies at work by arguing that those who experience menstruation face additional work or labour in the management of their own bodies through the menstrual cycle. We discuss how this additional labour replicates problematic elements that are identifiable in public health initiatives, in that it is individualised, requiring individual women and trans/non-binary people to navigate unsupportive workplaces. We present findings from an analysis of qualitative survey data that were completed by 627 participants working in higher education, revealing that employees' blood work comprises distinct difficulties that are related to the management of painful, leaking bodies, access to facilities, stigma, and balancing workload. We suggest developing supportive workplaces and public health policies, which refocus the responsibility for accessible, equal workplaces that accommodate menstruating employees, and those with gynaecological health conditions.

Validation of the Multidimensional Fatigue Inventory with Coronary Artery Disease Patients

BACKGROUND

Fatigue is a common distressing symptom in patients with coronary artery disease (CAD). The Multidimensional Fatigue Inventory (MFI) is used for measuring fatigue in various clinical settings. Nevertheless, its multidimensional structure has not been consistent across studies. Thus, we aimed to psychometrically evaluate the MFI in patients with CAD.

METHODS

In sum, 1162 CAD patients completed questionnaires assessing their subjective fatigue level (MFI-20), mental distress symptoms (HADS, STAI), and health-related quality of life (SF-36). Participants also completed exercise capacity (EC) testing.

RESULTS

Confirmatory factor analysis of the four-factor model, showed acceptable fit (CFI = 0.905; GFI = 0.895; NFI = 0.893, RMSEA = 0.077). After eliminating four items, confirmatory factor analysis testing showed improvement in the four-factor model of the MFI-16 (CFI = 0.910; GFI = 0.909; NFI = 0.898, RMSEA = 0.077). Internal consistency values were adequate for the total score and four MFI-16 subscales: General fatigue, physical fatigue, reduced activity, and mental fatigue with Cronbach's α range: 0.60-0.82. The inadequate value (Cronbach's α = 0.43) was received for the subscale of reduced motivation in both MFI-20 and MFI-16. Correlations between the MFI-16 and HADS, STAI, SF-36, and EC measures were statistically significant (all p's < 0.001).

CONCLUSIONS

The Lithuanian version of the modified MFI of 16 items showed good factorial structure and satisfactory psychometric characteristics, except for reduced motivation subscale.

CD200 and CD200R Expression on Peripheral Blood Lymphocytes and Serum CD200 Concentration as a New Marker of Endometriosis

The causes of endometriosis (EMS) remain unknown; however, a number of immunological abnormalities contribute to the pathogenesis of the disease. The cluster of differentiation-200 (CD200) and its receptor (CD200R) maintain peripheral self-tolerance by negatively regulating immune responses. In this comparative cross-sectional study, we investigated the expression of CD200 and CD200R on T and B lymphocytes and the serum level of soluble CD200 (sCD200) using flow cytometry and ELISA, respectively. Peripheral blood samples were collected from 54 female patients and 20 healthy, age-matched controls. Results were tested for correlation with disease severity and selected clinical parameters. We demonstrated that the differences in sCD200 levels (p = 0.001), the frequencies of CD200-positive T and B lymphocytes (p < 0.001 and p = 0.004, respectively), and the frequencies of CD200R-positive T and B lymphocytes (p < 0.001 for all comparisons) in the study group correlated positively with disease severity. Receiver operating characteristic (ROC) analysis indicated that aberrant expression of CD200/CD200R might serve as a marker to distinguish between EMS cases. Finally, negative co-stimulatory factors may contribute to the induction and persistence of inflammation associated with EMS. It seems that it is essential to determine whether alteration in the CD200/CD200R pathway can be therapeutically targeted in EMS.

Contribution of Chronic Fatigue to Psychosocial Status and Quality of Life in Spanish Women Diagnosed with Endometriosis

AIM

To analyze the levels of chronic fatigue in Spanish women with endometriosis and its relationship with their psychosocial status and quality of life (QoL).

METHODS

A total of 230 Spanish women with a clinical diagnosis of endometriosis were recruited. Chronic fatigue (Piper Fatigue Scale) and pelvic pain (Numeric Rating Scale) were evaluated. An on-line battery of validated scales was used to assess psychosocial status [Hospital Anxiety and Depression Scale, Scale for Mood Assessment, Pain Catastrophizing Scale, Pittsburgh Sleep Quality Index, Gastrointestinal Quality of Life Index, Female Sexual Function Index and Medical Outcomes Study-Social Support Survey] and QoL [Endometriosis-Health Profile questionnaire-30]. Associations between fatigue and both psychosocial and QoL outcomes were explored through multivariate regression models.

RESULTS

One-third and one-half of women showed moderate and severe fatigue, respectively. Fatigue was associated with higher anxiety and depression, poorer sleep quality, poorer sexual functioning, worse gastrointestinal health, higher catastrophizing thoughts, higher anger/hostility scores and lower QoL (p-values < 0.050). Moreover, fatigue and catastrophizing thoughts showed a mediating effect on the association between pelvic pain and QoL.

CONCLUSION

This work reveals the important role of fatigue in the association between pain, psychosocial status, and QoL of Spanish women with endometriosis.
