Impact of Endometriosis on Life-Course Potential: A Narrative Review

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.

Prevalence and Impact of Period and Pelvic Pain in Australian Adolescents: The PPEP Talk Schools Program

BACKGROUND

In 2018 the Australian Government launched the world's first National Action Plan for Endometriosis (NAPE). Of its three priorities 'Priority 1' was 'Education and Awareness'. In response, the Pelvic Pain Foundation of Australia was funded to deliver their Periods, Pain and Endometriosis Program (PPEP) Talk to a proportion of Australian schools. Since then, PPEP Talk has been delivered to over 110,000 students.

AIMS

This retrospective cross-sectional study investigated students assigned female at birth (AFAB) and the prevalence and impact of period and pelvic pain, interaction with health care services and knowledge of endometriosis.

MATERIALS AND METHODS

Multiple choice, pre and post PPEP Talk, paper survey responses between July 2022 and June 2023 were collected from 13,078 students AFAB.

RESULTS

52.6% of students reported regular severe period pain. 22.9% of students reported regularly missing school or work with their period. 21.5% of students had presented to a health professional for pain, and 5.7% had presented to an Emergency Department. 5.2% of students reported pelvic pain for more than 10 days per month. The prevalence and impact of period and pelvic pain varied across demographic variables. The proportion of students who knew what endometriosis was rose from 47.8% to 95.5% after the program.

CONCLUSIONS

The NAPE's objective to enhance education and awareness of endometriosis and period/pelvic pain was met. 100% of schools who received PPEP Talk want it to return. Wide discrepancies in the prevalence of pain within different demographics were identified, providing previously unknown data to improve and direct services.

Impact of COVID-19 on Endometriosis Patients: An Integrative Review

Background:

During the Covid-19 pandemic, people's lives worldwide have undergone extensive changes. The pandemic has worsened the condition of patients with chronic diseases like women with endometriosis.

Objective:

This study aims to summarize available evidence on the impact of the COVID-19 pandemic on physical symptoms, mental health, and medical care of patients with endometriosis.

Methods:

In the present integrative review using PRISMA guidelines, related articles published from December 2019 to July 2023 in databases including MEDLINE, Science Direct, Scopus, and Google Scholar in the English language were extracted.

Results:

After evaluating the criteria for inclusion and exclusion, a total of 23 articles were chosen and examined. This study represents an open window to investigate the impact of COVID-19 on women with endometriosis. The COVID-19 pandemic has affected the symptoms, mental well-being, and medical care of women with endometriosis.

Conclusions:

There is a perceived necessity to provide supportive care for patients during pandemic restrictions. Remote work has had an unanticipated advantage, and it is recommended that women with endometriosis continue to work from home after COVID-19 to maintain their workplace effectiveness.

The Role of Quercetin for the Treatment of Endometriosis and Endometrial Cancer: A Comprehensive Review

Endometrial glands and stroma can be seen outside the uterine cavity in endometriosis, a gynecological disorder linked to estrogen dependency. Hormonal therapies, surgical excision, and non-steroidal anti-inflammatory drug therapy are among the traditional endometriosis treatments, however, various side effects limit their efficacy. Therefore, it is vital to research complementary and alternative therapeutic modalities to decrease the side effects of conventional therapies. While the search for the best endometriosis treatment continues, the focus is being paid to the assistance provided by polyphenols, notably quercetin. A broad spectrum of health-improving benefits of quercetin includes interactions with endometriosis-related molecular targets such as cell proliferation, apoptosis, invasiveness, inflammation, and oxidative stress. According to already-known research, medicines that mimic the physiological effects of quercetin are good candidates for creating novel endometriosis therapies. This review aims to comprehensively review quercetin's potential as a non-pharmacological treatment for endometriosis by interacting with several cellular and molecular targets.

Her, His, and their journey with endometriosis: a qualitative study

Background

Endometriosis, impacting roughly 10% of reproductive-age women and girls globally, presents diagnostic challenges that can cause significant delays between symptom onset and medical confirmation. The aim of the current study was to explore the experience of women with endometriosis as well as that of their partners, from pre-diagnosis to diagnosis to post-diagnosis.

Methods

In-depth semi-structured interviews were conducted with 10 couples coping with endometriosis. Each partner was interviewed separately, and each interview was analyzed both individually and as part of a dyad, using the dyadic interview analysis method.

Results

Three main themes emerged: (i) "Relationship in the shadow of uncertainty": Coping with health symptoms prior to the formal endometriosis diagnosis; (ii) Coping together or alone when receiving the endometriosis diagnosis; and (iii) "The day after the diagnosis": Moving between adversity and growth.

Conclusions

The study's findings emphasize the importance of viewing the diagnosis from a dyadic perspective and comprehensively - that is, from pre-diagnosis to accepting the formal diagnosis to post-diagnosis. This journey can have a profound impact on both couple members, affecting their day-to-day functioning, communication, emotional and physical intimacy, and fertility.

Quality Improvement Report: The Sliding Sign Initiative-Facilitating Earlier Detection of Deep Endometriosis in an Academic US Department

A delayed diagnosis of endometriosis can significantly impact a patient's quality of life. To facilitate an earlier diagnosis, we implemented a modified pelvic US protocol that included use of the dynamic sliding sign (SS) maneuver to screen at-risk populations. The aim of this initiative was to improve both SS maneuver performance and SS reporting consistency to 80% and determine the number of new endometriosis cases identified after US. A quality improvement framework based on the plan-do-study-act (PDSA) methodology was used to develop and evaluate interventions. Eligible pelvic US studies were reviewed at regular intervals to track SS maneuver performance and SS reporting, with control charts used to detect intervention-related variation. A chart review of all abnormal SS cases was also performed. The project initiation (PDSA cycle 1) included protocol development and educational sessions. Reminder posters were placed during cycle 2 and revised in cycle 3, and the eligibility criteria were revised. Cycles 4 and 5 consisted of in-person discussions, distribution of a reference guide, and creation of a dictation software macro. In terms of results, sonographers performed the SS maneuver correctly in 52.1% of eligible patients after cycle 1, increasing to 83.9% by cycle 5. In the cases in which the SS maneuver was performed by the sonographer, after PDSA cycle 1, the SS was reported by the radiologist in 69% of cases (including both correct and incorrect interpretations), and both reported and interpreted correctly in 59% of cases. Thirty-seven patients were newly diagnosed with endometriosis after undergoing US of the SS. The objectives of our SS initiative were met, with improved SS US performance, improved SS reporting and interpretation, and a number of new endometriosis cases diagnosed. ©RSNA, 2024 Supplemental material is available for this article.

A Podcast on Patient and Physician Perspectives on the Management of Endometriosis and Relugolix Combination Therapy

Endometriosis is a common disease, affecting approximately 5-10% of reproductively aged women. Symptoms, such as painful periods, negatively impact an individual's quality of life; however, these symptoms are often normalized, leading to delays in diagnosis and treatment, and worsening of the disease. In this podcast, a reproductive endocrinologist (Dr Sanjay K Agarwal) and patient advocate (Tara Mangum) provide their perspectives on the diagnosis and management of endometriosis. They also discuss Relugolix combination therapy as a treatment option for patients with endometriosis.Podcast available for this article.

Management of Common Benign Gynecologic Diseases in Postmenopausal Women

This study investigated the impact of menopause on the progression and management of common benign gynecological conditions such as polycystic ovary syndrome, endometriosis, uterine fibroids, and adenomyosis. These conditions often present with menstruation-related symptoms such as irregular cycles, heavy bleeding, and pelvic pain. While these symptoms typically subside after menopause, the underlying pathology of such benign gynecological conditions may be differentially affected by the physiological changes associated with menopause, sometimes leading to exacerbation or additional management challenges. Although rare, the potential for malignant transformation remains a concern. This study aims to elucidate the shifts in management strategies from the reproductive years to postmenopause. It highlights the necessity for a tailored approach to hormone therapy and surgical interventions based on the individual patient's health profile and the specific characteristics of each condition.

Impact of endometriosis on partners: Results from the French EndoVie survey

OBJECTIVES

To study the impact of endometriosis on women's partners and evaluate the partners' perceptions and experiences.

STUDY DESIGN

Between January 21 and 28, 2020, a prospective cross-sectional web-based survey was conducted among partners of women suffering from endometriosis. The investigated sample group (n = 100) was taken from a targeted population among the Ipsos Access panel that collects data from 235,171 French subjects. The online questionnaire aimed to assess the impact of endometriosis on partners' well-being and daily life on a scale of 0 to 10 (where 0 represents very low impact and 10 represents very high impact).

RESULTS

The survey included 92 men and 8 women. Most of them (78 %) were at least 45 years of age and had been in a relationship for over 13 years (63 %). For 75 %, the diagnosis of endometriosis was made after the relationship had begun. At the time of endometriosis diagnosis, the dominant partners' feelings were concern, understanding, and compassion; however, 17 % also reported negative feelings. The average ratings for the impact of endometriosis on sexual relations and the couple's life were 4.2 ± 3.2 out of 10 and 3.6 ± 2.8 out of 10, respectively. The psychological impact, impact on leisure, and impact on relationships with friends and family were less significant. Endometriosis was also found to impact partners' emotions: 26 % reported that they did not often/very often understand the expectations of their partners when they underwent endometriosis-associated pain and 19 % reported feeling guilty about blaming their partner because of endometriosis.

CONCLUSION

This data provides new insights regarding the impact of endometriosis on partners of women suffering from the condition and highlights the importance of counselling in the management of endometriosis.

Early intervention and cumulative life course impairment in psoriasis: a review

Psoriasis is a chronic, systemic, inflammatory disease affecting the skin, joints and other organs. Psoriasis negatively affects patients' quality of life, causing social anxiety and negative coping, thus determining a cumulative life course impairment (CLCI). The concept of CLCI in psoriasis is reinforced by the understanding that psoriasis-associated comorbidities and stigma accumulate over a patient's life course, resulting from an interaction between the burden of stigmatization, physical and psychological comorbidities, coping strategies and external factors. The concept may help identify more vulnerable patients and facilitate more appropriate treatment decisions or earlier referrals. Although some potential risk factors for CLCI have been clarified, no all-encompassing screening tools are available. Patients at risk for CLCI should be identified by applying clinical, personal and psychosocial indicators and predictors individually. Early intervention in psoriasis treatment could improve long-term patient outcomes and modify the disease course. However, more research is needed to clearly define what constitutes 'early' intervention and to identify the most effective strategies for implementation. From a preventive point of view, it is helpful to identify early interventions aimed at reducing the risk of CLCI and establishing a new life course trajectory in patients with psoriasis. This review summarizes the latest developments in CLCI and psoriasis, highlighting knowledge gaps and future directions to make control of CLCI a possible goal for therapies.

Dietary and Nutritional Interventions for the Management of Endometriosis

Endometriosis is a chronic, complex, systemic inflammatory condition that impacts approximately 190 million girls and women worldwide, significantly impacting their quality of life. The effective management of endometriosis requires a multi-disciplinary and holistic approach, one that includes surgical and medical management, such as a laparoscopy and a chronic medical management plan, as well as dietary, nutritional, and lifestyle adjunct interventions, such as pelvic pain physiotherapy and acupuncture. There is growing evidence to support the role of dietary and nutritional interventions in the adjunct management of endometriosis-related pain and gastrointestinal symptoms. However, the implementation of these interventions is often not regulated, as patients with endometriosis often adopt self-management strategies. Diet and nutrition can modulate key players integral to the pathophysiology of endometriosis, such as, but not limited to, inflammation, estrogen, and the microbiome. However, it is unclear as to whether diet plays a role in the prevention or the onset of endometriosis. In this review, we discuss three key players in the pathogenesis of endometriosis-inflammation, estrogen, and the microbiome-and we summarize how diet and nutrition can influence their mechanisms, and consequently, the progression and manifestation of endometriosis. There is a major need for evidence-based, non-invasive adjunct management of this debilitating disease, and diet and nutritional interventions may be suitable.

Clinical Factors Affecting the Quality of Life of Women With Endometriosis

AIM

The study aimed to analyse selected clinical data affecting the quality of life of women with endometriosis.

DESIGN

A cross-sectional study.

METHOD

The study was conducted in 2020-2022 among 425 women with endometriosis receiving health care. A diagnostic survey method with a questionnaire technique was used. The research tools are the Endometriosis Health Profile and a standardised interview questionnaire.

RESULTS

Infertility, medical treatment and sexual intercourse were the dimensions of quality of life most poorly rated by respondents with endometriosis. Lower quality of life was linked to the presence of painful periods, the presence of pain during intercourse and having surgery for endometriosis.

CONCLUSION

The main clinical variables influencing the quality of life of women with endometriosis include problems with getting pregnant, the necessity for long-term therapy and sexual problems caused by the condition. The occurrence of painful menstruation, dyspareunia and having undergone surgery for endometriosis is associated with lower ratings of women's general quality of life.

IMPLICATIONS FOR THE PROFESSION

The study will help to develop a more holistic approach to caring for endometriosis patients. This will result in a better diagnosis, individualised therapy and psychological support, all of which will enhance the overall quality of life. The study's results may impact the development of health policies, endometriosis support services for women and public awareness initiatives.

IMPACT

The study highlighted key determinants affecting health-related quality of life for women with endometriosis. The analysis of clinical data revealed that infertility, treatment and dyspareunia are the dimensions of quality of life most poorly rated by women with endometriosis. These findings are significant for those providing care to women with endometriosis, as well as for policymakers responsible for the organisation of health care systems.

REPORTING METHOD

The STROBE guidelines.

Efficacy and safety of the combination of estetrol 15 mg/drospirenone 3 mg in a cyclic regimen for the treatment of endometriosis-associated pain and objective gynecological findings: a multicenter, placebo-controlled, double-blind, randomized study

OBJECTIVE

To evaluate the efficacy and safety of 24-week cyclic administration of estetrol (E4) (15 mg)/drospirenone (DRSP) (3 mg) in Japanese patients with endometriosis.

DESIGN

A 24-week, multicenter, randomized, double-blind, placebo-controlled, parallel-group study.

SETTING

Twenty-five study centers in Japan.

PATIENT(S)

A total of 162 Japanese women diagnosed with endometriosis.

INTERVENTION(S)

Participants were randomly allocated to the E4/DRSP group or the placebo group. In the E4/DRSP group, participants were orally administered one tablet containing E4 (15 mg) and DRSP (3 mg) daily for 24 days, followed by one placebo tablet for 4 days for a hormone-free interval, constituting a 1-cycle regimen. One placebo tablet was administered once daily for 28 days to participants in the placebo group. The treatments were continued for six cycles (24 weeks) throughout the confirmatory period.

MAIN OUTCOME MEASURE(S)

Changes in visual analogue scale (VAS) scores for the most severe pelvic pain (lower abdominal and back pain) from baseline to six treatment cycles at the end of the confirmatory study period.

RESULT(S)

Estetrol/drospirenone showed changes in the mean VAS scores for the most severe pelvic pain (-33.2 mm) from baseline to the end of the 6-cycle treatment. The between-group difference was significant (-8.5 mm; 2-sided 95% confidence interval, -16.1 to -0.9 mm), showing superiority to placebo. The responder rates, ≥30% and ≥50% reductions in the VAS scores from baseline, were higher in the E4/DRSP group than in the placebo group: 53.2% vs. 29.6% and 36.4% vs. 12.3%. Objective gynecological findings (induration of the cul-de-sac, pelvic tenderness, and limited uterine mobility) were significantly improved by E4/DRSP treatment, and the proportions of stable and worsened participants were significantly lower than in the placebo group. Estetrol/drospirenone decreased the size of endometriomas and improved quality of life, on the basis of quality of life-related questionnaires and global impression scores. No safety concerns were observed with E4/DRSP treatment. Few differences were observed in the proportion of participants with hemostasis parameters outside the reference range between the E4/DRSP and placebo groups.

CONCLUSION(S)

Estetrol/drospirenone effectively treats endometriosis-associated pain and improves gynecological findings. Estetrol/drospirenone may be a safe, new option for endometriosis treatment with a potentially decreased risk of thromboembolic events.

Predictors of partnership and sexual satisfaction and dyadic effects in couples affected by endometriosis and infertility

PURPOSE

Endometriosis and infertility are associated with impaired partnership and sexuality of the patients, but also of their male partners. Also, endometriosis is one of the most common causes of infertility, resulting in a large overlap of both pathologies. The aim of this study was to determine the association of different predictors of partnership and sexual satisfaction and dyadic effects in couples with endometriosis and infertility.

METHODS

A cross-sectional study was conducted with n = 62 women with endometriosis and n = 46 partners, including a total of n = 44 couples, some of whom were affected by infertility. The questionnaire included items on partnership, sexuality, depression, social support, and desire for a child. Multiple linear regression and the actor-partner-interdependence-model were used for analysis.

RESULTS

Significant dyadic effects only occurred in couples with both endometriosis and infertility. Depression showed a significant negative actor effect in men for partnership satisfaction and a negative actor and partner effect in women for sexuality satisfaction (p < .05). For women, social support showed a significant positive actor effect for partnership satisfaction (p < .05), age showed a significant actor and partner effect for sexuality satisfaction (p < .05).

CONCLUSION

The results show a significant association of endometriosis and infertility with partnership and sexuality satisfaction. Infertility could be a decisive factor. However, the large overlapping of both endometriosis und infertility in many couples support the importance of further studies to differentiate between the both effects.

Machine Learning-Based Detection of Endometriosis: A Retrospective Study in A Population of Iranian Female Patients

BACKGROUND

Endometriosis, is a prevalent condition among women of childbearing age, characterized by the presence of ectopic endometrial glands. It is associated with pelvic pain and infertility. Unfortunately, the diagnosis of endometriosis is often delayed in many patients. While laparoscopic investigation is required for a definitive diagnosis, physical examination combined with ultrasonography can provide reasonably accurate detection. Machine learning (ML) techniques have shown promise tools in medical imaging and diagnostics. However, there is a lack of sufficient ML studies focusing on Iranian endometriosis female patients. In this study, we aimed to compare the diagnostic accuracy of different ML algorithms for endometriosis detection.

MATERIALS AND METHODS

In this retrospective study, our objective was to assess the diagnostic accuracy of different ML algorithms in classifying suspicious cases of endometriosis using ultrasonographic signs. Our data set consisted of 505 patients, among which 149 were confirmed cases of endometriosis. We divided the data set into training and test sets to train and evaluate the performance of the ML models. To ensure robust evaluation, we employed stratified 5-fold cross-validation and calculated the area under the receiver operating characteristic curve (AUC) as a measure of model performance.

RESULTS

In the test set, a total of 37 out of 127 patients (29.1%) were diagnosed with endometriosis, while in the training set, 112 out of 378 patients (29.6%) were confirmed to have the condition. Sensitivities ranged from 59.5 to 75.7%, and specificities ranged from 71.7 to 83.3%. Notably, the SVM, Random Forest, Extra-Trees, and Gradient Boosting models exhibited the highest performance, with AUCs of 0.76.

CONCLUSION

Our study supports the use of ML models for the screening and diagnosis of endometriosis. The superior performance of the SVM, Random Forest, Extra-Trees, and Gradient Boosting models, as indicated by their high AUCs, suggests their potential as valuable tools in improving the accuracy of endometriosis detection.

Cardiovascular risks and endothelial dysfunction in reproductive-age women with endometriosis

Endometriosis is a prevalent gynecological condition, affecting around 10% of reproductive-age women. Inflammatory processes associated with endometriosis may contribute to endothelial dysfunction. Increased skin accumulation of advanced glycation end-products (AGEs), reflecting arterial stiffness, potentially links endometriosis with elevated risk of cardiovascular events. We hypothesized that patients with endometriosis have impaired endothelial function as well as increased arterial stiffness and AGE skin accumulation, compared to healthy controls. We compared endothelial function, arterial stiffness, and levels of AGEs in patients suffering from endometriosis and in healthy controls. The study included 45 women aged 20 to 40: 21 patients with endometriosis and 24 healthy controls, matched in terms of age, BMI, and blood pressure values. Endo-PAT 2000 device was used for non-invasive assessment of (i) endothelial function, expressed as Reactive Hyperemia Index (RHI), and (ii) arterial stiffness, expressed as Augmentation Index (AI) and Augmentation Index at 75 heart beats/min (AI@75). Endothelial dysfunction was defined as an RHI value ≤ 1.67. AGE Reader device was used for non-invasive evaluation of skin AGE level accumulation. Patients with endometriosis had lower mean RHI values (1.69 ± 0.54 vs. 2.02 ± 0.48, p = 0.037) and a higher prevalence of endothelial dysfunction, (52.4% vs. 20.8%, p = 0.027) compared to healthy controls. Skin AGE level was higher in patients with endometriosis, compared to controls (2.00 ± 0.57 vs. 1.70 ± 0.24, p = 0.013). There were no significant differences in AI and AI@75 between the two groups. Patients with endometriosis have impaired endothelial function and higher AGE skin accumulation, which are well-established preclinical manifestations of increased cardiovascular risk. There is a great need for comprehensive cardiovascular risk assessments in women with endometriosis to prevent the development of potential atherosclerotic-based complications.

Exercise and endometriosis-is there a promising future? A narrative review

BACKGROUND

Endometriosis is the leading cause of chronic pelvic pain in women of reproductive age with debilitating effects on quality of life, yet no cure exists. Exercise yields the potential in providing women with a non-invasive, non-pharmacological method of symptom control.

AIM(S)

Present up-to-date knowledge regarding how exercise may contribute to the management of endometriosis-related symptoms.

OBJECTIVE(S)

Discuss: 1. The pathophysiology surrounding exercise and endometriosis. 2. The role of exercise in endometriosis symptom control.

RATIONALE

Scientific literature has alluded to exercise being a favourable factor in the management of endometriosis-related symptoms. Moreover, current clinical guidelines for endometriosis fail to reflect the aforementioned benefits of exercise.

SEARCH STRATEGY

A search strategy using the terms 'endometriosis', 'endometriomas', 'exercise', and 'physical activity' was devised. Pubmed, Medline, Cochrane reviews, and Embase were reviewed.

INCLUSION CRITERIA

Interventional studies, within-subjects studies, randomised-control trials, systematic reviews, meta-analysis, cohort studies, publication since 2000.

EXCLUSION CRITERIA

Non-English publications, non-human studies.

RESULTS

Numerous studies have suggested positive effects for endometriosis patients who performed exercise exclusively or in conjunction with other therapies. Improvements in pain levels, quality of life, anxiety, and depression were noted.

DISCUSSION

Current research outlines promise regarding the potential benefit of exercise prescribing in patients with endometriosis as well as a synergy between exercise and hormonal therapies for the management of endometriosis-related symptoms. However, the current paucity of high-quality robust studies investigating these aspects of endometriosis management is an apparent obstacle to progression in this area.

CONCLUSION

For clinicians to incorporate exercise in managing endometriosis, clear recommendations regarding advice and benefits are needed.

A prospective study of dietary patterns and the incidence of endometriosis diagnosis

BACKGROUND

Although endometriosis is a common condition-affecting ∼10% of premenopausal individuals-its etiology is unknown. Diet receives a lot of attention from patients, but studies of the role of diet are limited. Examining dietary patterns is essential to provide new insight.

OBJECTIVE

We sought to determine whether dietary patterns are associated with laparoscopically-confirmed endometriosis diagnosis.

STUDY DESIGN

We conducted a prospective cohort study among 81,997 premenopausal participants of the Nurses' Health Study II, who were followed from 1991-2015. Diet was assessed with validated food frequency questionnaires every 4 years. We examined 6 dietary patterns: Western, Prudent, Alternative Healthy Eating Index, Dietary Approaches to Stop Hypertension, an estrogen-associated pattern, and a proinflammatory pattern. Cox proportional hazard ratios and 95% confidence intervals were used to quantify the association between each of these patterns and laparoscopically-confirmed endometriosis diagnosis.

RESULTS

Three thousand eight hundred ten incident cases of endometriosis were diagnosed during 24 years of follow-up. Adherence to the Alternative Healthy Eating Index, reflecting a healthier dietary pattern, was associated with a 13% lower risk of endometriosis diagnosis (fifth vs first quintile 95% confidence interval, 0.78-0.96; Ptrend=.02). Participants in the highest quintile of the Western dietary pattern, characterized by high intake of red meat, processed meat, refined grains, and desserts, had a 27% higher risk of endometriosis diagnosis than those in the lowest quintile (95% confidence interval, 1.09-1.47; Ptrend=.004). The Prudent, Dietary Approaches to Stop Hypertension, and estrogen-associated dietary patterns did not demonstrate clear associations with endometriosis risk, and there was the suggestion of a higher risk of endometriosis diagnosis among those with a higher proinflammatory diet score (hazard ratio for fifth vs first quintile, 1.10 [95% confidence interval, 0.99-1.23]; Ptrend=.01).

CONCLUSION

Our results suggest that consuming a dietary pattern that adheres to the Alternative Healthy Eating Index-2010 recommendations lowers the risk of endometriosis diagnosis, potentially through a beneficial impact on pelvic pain. In addition, consuming a less healthy diet high in red/processed meats and refined grains may have a detrimental impact on endometriosis symptoms.

Pelvic myofascial pain is associated with restriction of sexual activity in women with pelvic pain: a cross-sectional study

Background Dyspareunia and restriction of sexual activity are often reported by patients with chronic pelvic pain, but less is known about which conditions or factors contribute most to these symptoms. Methods This is a cross-sectional study of consecutive new patients who presented to a chronic pelvic pain and endometriosis referral clinic between January 2013 and December 2015. Patients completed a detailed questionnaire prior to their first visit and underwent a comprehensive standardised pelvic examination at their first visit. Patients were grouped according to description of sexual activity as 'normal activity without pain', 'normal activity but painful', 'severely restricted by pain', or 'absent due to pain.' Primary outcome was restriction of sexual activity due to pain. Multinomial logistic regression was performed with 'normal activity without pain' group as reference category and adjusted for age, depression, history of endometriosis, and pelvic myofascial pain. Results Over half of the 187 patients with chronic pelvic pain described severely restricted (n =75, 40.1%) or absent (n =21, 11.2%) sexual activity due to pain. Pelvic myofascial pain was highly prevalent in this population and pelvic myofascial tenderness score was associated with higher odds of sexual activity that was severely restricted by pain (OR 1.05, 95% CI 1.01-1.09, P =0.006) or absent due to pain (OR 1.09, 95% CI 1.04-1.13, P Conclusion Dyspareunia and sexual dysfunction are highly prevalent among patients with chronic pelvic pain, and pelvic myofascial pain is strongly associated with restriction of sexual activity due to pain.

Limitations and perspectives of the novel salivary test for endometriosis: an open web-based survey study of German gynecologic healthcare providers

INTRODUCTION

The description of a salivary miRNA signature for endometriosis has led to the development of a non-invasive diagnostic test. Current healthcare provider practices regarding the test remain uncaptured. The application of this test in practice was examined in a web-based survey, with the aim to provide their opinions on it.

METHODS

We conducted an open web-based survey study between November 2023 and January 2024. Members of the German society of gynecologic endoscopy (Arbeitsgemeinschaft gynäkologische Endoskopie, AGE), society of endometriosis (Arbeitsgemeinschaft Endometriose, AGEM), and the endometriosis research foundation (Stiftung Endometriose Forschung, SEF) were contacted per e-mail twice. Participants' data were anonymized. Differences in responses based on self-reported expertise in the field (basic knowledge, specialized knowledge, expert) were assessed using the χ2-test or Fisher's exact test. Statistical significance was set as p < 0.05.

RESULTS

In total 141 of 190 respondents completely responded to the survey (> 75% of the questions of the survey). Twenty-one physicians reported having experience with the test, while most participants had at least specialized knowledge on the field (112/141). In terms of specific questions, more than 90% found the costs high; almost 85% did not believe that the test replaces standard diagnostic tools (histology, clinical examination, and sonography). Eighty-six providers supported the use of the test in adolescents. Gynecologists with basic knowledge had a more positive attitude compared with more experienced ones in terms of usefulness (Fisher's exact test, p < 0.001). Significant differences were demonstrated between expertise groups regarding (not only) applicability in adolescents (Fisher's exact test, p = 0.004), and using the test for screening purposes (χ2-test, p = 0.002).

DISCUSSION

Despite the promising benefits of a salivary test for endometriosis, German healthcare providers would not change current practices. Nevertheless, less experienced colleagues were more positive towards the test.

Understanding the impact of endometriosis on women's life: an integrative review of systematic reviews

BACKGROUND

Endometriosis is a challenging chronic condition with a significant impact on women's well-being. This systematic review of systematic reviews aims to assess the evidence investigating the intricate interplay between endometriosis and quality of life (QoL).

METHODS

A systematic review was performed for English-language studies up to January 2022 to identify systematic reviews with and without meta-analysis analyzing quantitative or qualitative data The following databases were searched: Scopus, PubMed, Embase, Web of Science and Cochrane Central Register of Controlled Trials. Participants/population were women with endometriosis, and the outcomes included were all reported outcomes evaluating the impact of endometriosis on women's QoL (PROSPERO 2021 CRD42021289347).

RESULTS

15 systematic reviews were identified. 8 included meta-analysis: 4 explored the prevalence of mental health problems, and 1 analyzed, respectively, the overall impact of endometriosis, headache migraine, and sexual function. 7 articles reported on the mental consequences, and three sexual functioning. One was a qualitative review. The impact of the relationships with the healthcare system was analyzed in 3 reviews. Pain is a hallmark of endometriosis. Infertility and sexual problems are also frequent. Depression, anxiety, and stress represent significant contributors to lessening women's QoL. Women have frustrating relationships with the healthcare system: the complex and long diagnostic process, lack of treatment effectiveness, and persistence of symptoms contribute to emotional challenges. Negative cognitive patterns developed by women with emotional distress, such as catastrophizing and fear-avoidance behaviors, amplify the experience of pain.

CONCLUSION

The limitations of this review are the high degree of heterogeneity of papers that include many factors, including comorbidities, and use of medical care that may impact QoL, and that most of them were cross-sectional. Endometriosis is a chronic disease that significantly impacts all domains of women's lifes. Pain, infertility, and stress linked with depression, and anxiety significantly influence QoL. Women are dissatisfied with the care they receive.

Endometriosis risk and hormonal contraceptive usage: A nationwide cohort study

OBJECTIVE

To investigate whether an early need of hormonal contraceptive (HC), or a failure to find a suitable method, are warning signs for endometriosis.

DESIGN

A retrospective cohort study.

SETTING

Sweden.

POPULATION

The cohort consisted of 720 805 women aged 12-27 years during the period 2005-2017. All women, regardless of whether they received a diagnosis of endometriosis or not (reference group), were included.

METHODS

We used data from Swedish national registers. Risks are expressed as crude and adjusted hazard ratios (HRs and aHRs, respectively) with 95% confidence intervals (95% CIs), adjusted for age, education level, civil status, parity, country of birth, and diagnoses of infertility, dysmenorrhea or depression.

MAIN OUTCOME MEASURES

A diagnosis of endometriosis between 12 and 27 years of age.

RESULTS

During this period, 3268 women were diagnosed with endometriosis (0.45%). Women who started HC at the ages of 12-14 years had a higher risk of receiving the diagnosis (aHR 2.53, 95% CI 2.21-2.90) than those who began at age 17 years or older. Having tried more types of HCs was associated with a twofold increased risk of endometriosis (more that three types of HC, aHR 2.31, 95% CI 1.71-3.12). Using HC for more than 1 year was associated with a decreased risk of endometriosis (>1 year, aHR 0.53, 95% CI 0.48-0.59). Women with endometriosis more commonly had dysmenorrhea, depression or infertility.

CONCLUSIONS

The use of HCs at an early age and a failure to find a suitable HC were identified as warning signs of later receiving an endometriosis diagnosis. A longer duration of HC usage reduced the risk of receiving the diagnosis.

Uncovering moderators of pain perception by women with endometriosis from Latin America and Spain: the roles of sociodemographics, racial self-identity, and pain catastrophizing

ABSTRACT

A cross-sectional multinational collaborative study on women with endometriosis from Latin America and Spain uncovered high levels of painful symptomatology and high pain catastrophizing scores. Associations between pain perception/catastrophizing and race/ethnicity have been documented. This study was conducted to uncover factors moderating pelvic pain severity, including socioeconomic variables, self-identified race, and pain catastrophizing in women with endometriosis from Latin America and Spain, a population encompassing diverse racial and sociocultural contexts. Self-reported data on demographics, clinical history, Ob-Gyn history, pelvic pain intensity, and pain catastrophizing were collected with the Spanish World Endometriosis Research Foundation (WERF) Endometriosis Phenome Project (EPhect) Clinical Questionnaire (ECQ). Multiple logistic regression was conducted to analyze effects of self-identified race, demographic clusters (defined as countries with similar racial population distribution), socioeconomic factors, and pain catastrophizing on reporting severe vs moderate-mild levels of dysmenorrhea, dyspareunia, and pelvic pain. Self-identified race did not affect the likelihood of reporting severe pelvic pain; however, there were significant differences in reporting severe dysmenorrhea at worst among demographic clusters. Older age was associated with severe dyspareunia at worst and recent pelvic pain. Pain catastrophizing score was highly predictive of reporting most types of severe pelvic pain, regardless of race and demographic cluster. These results negate a role of racial categories as moderator of pain in women from Latin America and Spain and support integration of pain catastrophizing assessments and psychological interventions into the pain management plan to enhance therapeutic outcomes and QoL for patients with endometriosis.

Interplay between Bile Acids and Intestinal Microbiota: Regulatory Mechanisms and Therapeutic Potential for Infections

Bile acids (BAs) play a crucial role in the human body's defense against infections caused by bacteria, fungi, and viruses. BAs counteract infections not only through interactions with intestinal bacteria exhibiting bile salt hydrolase (BSH) activity but they also directly combat infections. Building upon our research group's previous discoveries highlighting the role of BAs in combating infections, we have initiated an in-depth investigation into the interactions between BAs and intestinal microbiota. Leveraging the existing literature, we offer a comprehensive analysis of the relationships between BAs and 16 key microbiota. This investigation encompasses bacteria (e.g., Clostridioides difficile (C. difficile), Staphylococcus aureus (S. aureus), Escherichia coli, Enterococcus, Pseudomonas aeruginosa, Mycobacterium tuberculosis (M. tuberculosis), Bacteroides, Clostridium scindens (C. scindens), Streptococcus thermophilus, Clostridium butyricum (C. butyricum), and lactic acid bacteria), fungi (e.g., Candida albicans (C. albicans) and Saccharomyces boulardii), and viruses (e.g., coronavirus SARS-CoV-2, influenza virus, and norovirus). Our research found that Bacteroides, C. scindens, Streptococcus thermophilus, Saccharomyces boulardii, C. butyricum, and lactic acid bacteria can regulate the metabolism and function of BSHs and 7α-dehydroxylase. BSHs and 7α-dehydroxylase play crucial roles in the conversion of primary bile acid (PBA) to secondary bile acid (SBA). It is important to note that PBAs generally promote infections, while SBAs often exhibit distinct anti-infection roles. In the antimicrobial action of BAs, SBAs demonstrate antagonistic properties against a wide range of microbiota, with the exception of norovirus. Given the intricate interplay between BAs and intestinal microbiota, and their regulatory effects on infections, we assert that BAs hold significant potential as a novel approach for preventing and treating microbial infections.

Endometriosis: A Comprehensive Exploration of Inflammatory Mechanisms and Fertility Implications

Endometriosis is a prevalent gynecological disorder characterized by the ectopic growth of endometrial-like tissue outside the uterus. This condition poses significant challenges due to its chronic nature, debilitating symptoms such as pelvic pain and infertility, and substantial impact on quality of life. Central to the pathogenesis of endometriosis are inflammatory mechanisms that perpetuate tissue proliferation, adhesion formation, and immune dysregulation within the pelvic cavity. Inflammation plays a pivotal role in the development and progression of endometriosis, influencing the severity of symptoms and complications associated with the disease. Dysregulated immune responses contribute to the persistence of ectopic endometrial implants, exacerbating pelvic pain and other symptoms experienced by affected individuals. Moreover, the inflammatory milieu created by endometriotic lesions disrupts normal ovarian function, impairs follicular development, and compromises reproductive outcomes, thereby posing challenges to fertility. This review comprehensively explores the inflammatory mechanisms underlying endometriosis and their implications for fertility. Synthesizing current research and clinical insights elucidates the intricate interplay between inflammation, disease progression, and reproductive health outcomes. Understanding these complex interactions is essential for developing targeted diagnostic strategies and optimizing therapeutic approaches tailored to alleviate symptoms and improve fertility outcomes in individuals with endometriosis. Ultimately, this review aims to enhance the understanding of endometriosis pathophysiology, inform clinical practice, and stimulate further research to advance personalized care and management strategies for this challenging condition.

Questionnaire-based screening of adolescents and young adult women can identify markers associated with endometriosis

STUDY QUESTION

Do adolescents and young adult women (YAW) with histologically proven endometriosis present a specific clinical history?

SUMMARY ANSWER

Questionnaire screening of adolescents and YAW can identify clinical markers associated with histologically proven endometriosis.

WHAT IS KNOWN ALREADY

Some validated questionaries can contribute to an earlier endometriosis diagnosis in adults. None of these scores, however, have been validated for adolescents or YAW.

STUDY DESIGN, SIZE, DURATION

This was an observational cross-sectional study using prospectively recorded data performed between January 2005 and January 2020 in a single university tertiary referral centre for endometriosis diagnosis and management. After a thorough surgical examination of the abdomino-pelvic cavity, women with histologically proven endometriosis were allocated to the endometriosis group, and symptomatic women without evidence of endometriosis were allocated to the endometriosis-free control group. The endometriotic patients were allocated into two sub-groups according to their age: adolescent (≤20 years) and YAW (21-24 years).

PARTICIPANTS/MATERIALS, SETTING, METHODS

Adolescents and YAW ≤24 years of age were operated for a symptomatic benign gynaecological condition with signed informed consent. A standardized questionnaire was prospectively completed in the month before the surgery and included epidemiological data, pelvic pain scores, family history of endometriosis, and symptoms experienced during adolescence. The study searched for correlations by univariate analysis to determine clinical markers of endometriosis in adolescents and YAW compared with endometriosis-free control patients.

MAIN RESULTS AND THE ROLE OF CHANCE

Of the 262 study participants, 77 women were adolescents (≤20 years of age) and 185 patients (70.6%) were YAW. The endometriosis group included 118 patients (45.0%) and 144 (55.0%) were assigned to the control group. A family history of endometriosis, absenteeism from school during menstruation, history of fainting spells during menstruation, and prescription of oral contraceptive pills for intense dysmenorrhea were significantly more frequently observed in the endometriotic patients. The prevalence and mean pain scores for dysmenorrhea, deep dyspareunia, non-cyclic chronic pelvic pain and gastrointestinal and lower urinary tract symptoms were significantly greater in the endometriosis group, as was experienced rectal bleeding.

LIMITATIONS, REASONS FOR CAUTION

The study was performed in a single referral centre that treats patients with potentially more severe disease. This questionnaire was evaluated on a population of patients with an indication for endometriosis surgery, which can also select patients with more severe disease. Women with asymptomatic endometriosis were not considered in this study. These factors can affect the external validity of this study.

WIDER IMPLICATIONS OF THE FINDINGS

Patient interviews are relevant to the diagnosis of endometriosis in adolescents and YAW. Combined with imaging and clinical examination, this approach will enable earlier diagnosis and treatment, while remaining non-invasive and rapid.

STUDY FUNDING/COMPETING INTEREST(S)

The study received no funding from external sources. There are no conflicts of interest.

The causal relationship of depression, anxiety, and neuroticism with endometriosis: A bidirectional 2-sample Mendelian randomization study

Endometriosis, identified by the abnormal growth of endometrial cells beyond the inner lining of the uterus, often manifests through symptoms like painful menstruation and challenges in conceiving. Observational studies suggest that endometriosis is often comorbid with mental disorders, including anxiety and depression. The nature of these connections, whether they are causal, is still debated and calls for further empirical evidence. We utilized a bidirectional 2-sample Mendelian randomization (MR) approach, harnessing genome-wide association study data to explore the connections among depression, anxiety, neuroticism, and endometriosis. To scrutinize the causative connections between mental health issues and endometriosis, Inverse Variance Weighting (IVW) was employed as the primary analytical tool, complemented by Weighted Median Estimation, Simple mode, Weighted mode, and MR-Egger regression for additional analysis. To examine the potential for reverse causation, reverse MR was applied. To strengthen the reliability of our findings, we carried out sensitivity analyses that included heterogeneity tests, tests for pleiotropy, and leave-one-out analyses. The IVW analysis revealed a significant correlation between the genetic inclination towards depression and a heightened risk of developing endometriosis [Odds Ratio (OR) = 1.151, 95% Confidence Interval (CI) = 1.025-1.293, P = .017]. Similarly, a genetic predisposition to neuroticism was significantly associated with an increased risk of endometriosis (OR = 1.128, 95% CI = 1.038-1.226, P = .004). However, no causative link was found between genetic susceptibility to anxiety and the occurrence of endometriosis. Reverse MR analysis did not support a bidirectional genetic susceptibility between endometriosis and psychiatric disorders. The MR analysis presents genetic data supporting the notion that depression and neuroticism are risk factors for endometriosis. Conversely, it found no evidence of a causal connection between anxiety and the development of endometriosis. Enhancing mental health treatment should be considered a preventive measure against endometriosis.

Endometriosis in Transgender Men: Bridging Gaps in Research and Care-A Narrative Review

Endometriosis is a debilitating gynecological condition commonly seen in individuals designated female at birth; however, there has been limited research focused on its prevalence and impact among transgender men. This narrative review aims to fill a critical knowledge gap by exploring the epidemiology, clinical manifestations, management strategies, and quality-of-life implications of endometriosis among transgender individuals who identify as male. Specifically, this study seeks to estimate the prevalence rates and describe the symptoms experienced by transgender men undergoing testosterone therapy. Additionally, it addresses the diagnostic challenges posed by hormonal treatments and the lack of culturally competent healthcare services for this population. Recent molecular studies indicate that hormonal imbalances, such as increased estrogen synthesis and progesterone resistance, are significant factors in the persistence of endometriosis symptoms despite testosterone therapy. Moreover, evidence suggests that testosterone therapy may not always suppress endometrial activity completely, contributing to the persistence of symptoms in some individuals. Endometriosis in transgender men requires personalized approaches that consider both testosterone therapy and its interactions with endometriosis, as well as fertility preservation and the psychosocial aspects of treatment. This review emphasizes the necessity of taking an inclusive approach in both research and clinical practice to improve healthcare outcomes for this underserved population. The results demonstrate how continued research, education, and healthcare services tailored specifically to transgender men are necessary to better understand and treat endometriosis, thus improving both their overall health and quality of life.

Establishment of a diagnostic model of endometriosis based on disulfidptosis-related genes

OBJECTIVES

We aimed to establish a diagnostic model of endometriosis (EM) based on disulfidptosis-related genes (DRGs).

MATERIALS AND METHODS

The mRNA expression data of EM were downloaded from the gene expression omnibus database and subjected to differential analysis, and co-expression analysis was performed based on 10 disulfidptosis genes to acquire DRGs. The differentially expressed DRGs were subjected to biofunctional analysis. Lasso analysis and support vector machine-recursive feature elimination (SVM-RFE) analysis were employed to extract the intersection of feature genes as biomarkers, and the diagnostic values of biomarkers for EM were evaluated based on receiver operating characteristic curves. The correlations between biomarkers and the immune microenvironment were assessed by Pearson analysis of biomarkers and immune cell infiltration levels.

RESULTS

Transforming growth factor β stimulated protein clone 22 domain family member 4 (TSC22D4), and F-box/SPRY domain-containing protein 1 (FBXO45) worked as the diagnostic classifiers in EM, with an obvious decrease in FBXO45 expression and an evident increase in TSC22D4 expression. The areas under the curves of FBXO45 and TSC22D4 were 0.752 and 0.706, respectively, and the area of FBXO45 combined with TSC22D4 reached 0.865, suggesting that TSC22D4 and FBXO45 had high predictive values. The diagnostic markers were closely correlated with immune cell infiltration.

CONCLUSION

The diagnostic markers constructed based on disulfidptosis are good predictors for EM, which have close correlations with EM.

Endometriosis, Pain, and Related Psychological Disorders: Unveiling the Interplay among the Microbiome, Inflammation, and Oxidative Stress as a Common Thread

Endometriosis (EM), a chronic condition in endometrial tissue outside the uterus, affects around 10% of reproductive-age women, significantly affecting fertility. Its prevalence remains elusive due to the surgical confirmation needed for diagnosis. Manifesting with a range of symptoms, including dysmenorrhea, dyschezia, dysuria, dyspareunia, fatigue, and gastrointestinal discomfort, EM significantly impairs quality of life due to severe chronic pelvic pain (CPP). Psychological manifestations, notably depression and anxiety, frequently accompany the physical symptoms, with CPP serving as a key mediator. Pain stems from endometrial lesions, involving oxidative stress, neuroinflammation, angiogenesis, and sensitization processes. Microbial dysbiosis appears to be crucial in the inflammatory mechanisms underlying EM and associated CPP, as well as psychological symptoms. In this scenario, dietary interventions and nutritional supplements could help manage EM symptoms by targeting inflammation, oxidative stress, and the microbiome. Our manuscript starts by delving into the complex relationship between EM pain and psychological comorbidities. It subsequently addresses the emerging roles of the microbiome, inflammation, and oxidative stress as common links among these abovementioned conditions. Furthermore, the review explores how dietary and nutritional interventions may influence the composition and function of the microbiome, reduce inflammation and oxidative stress, alleviate pain, and potentially affect EM-associated psychological disorders.

Vilaprisan for the treatment of symptomatic endometriosis: results from a terminated phase 2b randomized controlled trial

Objective

To evaluate the efficacy and safety of 2 doses of vilaprisan vs. placebo in participants with symptomatic endometriosis.

Design

Multicenter, randomized, double-blind, placebo-controlled, parallel-group phase 2b trial (NCT03573336). The initially planned sample size was 315 patients. Recruitment was paused to assess long-term toxicity findings in rodents; although the findings were assessed as likely to be of limited clinical relevance in humans, the study was closed by the sponsor. During the pause, enrolled patients completed 3 or 6 months of treatment per their assigned regimen.

Setting

University hospitals, a regional hospital, and a private clinic.

Patients

Premenopausal adults with confirmed endometriosis and moderate-to-severe pelvic pain (≥4/10 on a numerical rating scale) were enrolled. Inclusion required protocol adherence, including ≥24 diary entries, and an average pain score of ≥3.5.

Intervention

Participants were randomly assigned 1:1:1 to receive vilaprisan (2 mg), vilaprisan (4 mg), or placebo.

Main Outcome Measures

The primary outcome was a change in the 7-day mean "worst pain" (per the endometriosis symptom diary item 1) from baseline to month 3. All analyses were descriptive only.

Results

Eight participants were randomly assigned to treatment before the study pause: 6 received vilaprisan (4 mg, n = 4 and 2 mg, n = 2), and 2 received placebo. The 6 vilaprisan recipients experienced an improvement in endometriosis-associated pelvic pain, whereas the 2 placebo recipients experienced no change or increased pain; all 8 participants had decreased use of pain medication. Bleeding intensity decreased from baseline in the vilaprisan group.

Conclusion

The study findings suggest that vilaprisan may improve outcomes in patients with endometriosis. Further studies in larger populations would be needed to accurately assess treatment effects.

Menstrual Blood Donation for Endometriosis Research: A Cross-Sectional Survey on Women's Willingness and Potential Barriers

An anonymous online survey in French was used to assess if endometriosis patients would be as ready as unaffected women to donate their menstrual blood for biological research on endometriosis and evaluate potential barriers to such donation. It was distributed in September 2022 by social media and two mailing lists, including a French patient organization. The questionnaire assessed participant age and brief medical history (hormonal contraception, endometriosis diagnosis, type of endometriosis), menstrual experience (menstrual blood abundance, dysmenorrhea), and whether participants would donate menstrual blood. Women who self-declared with an established endometriosis diagnosis versus no endometriosis were compared. Seven hundred seventy-eight women answered the survey. Among women with menstruation (n = 568), 78% are willing to donate menstrual blood for research. Importantly, this proportion was higher in women who declared having an established endometriosis diagnosis (83%, n = 299) compared to self-declared unaffected women (68%, n = 134, p < 0.001). The previous use of a menstrual cup and dysmenorrhea were significantly associated with the willingness to donate menstrual blood, while the use of hormonal contraception was significantly associated with an unwillingness to donate. Only the previous use of the menstrual cup had a predictive value for menstrual blood donation. No significant relationship was observed between menstrual blood donation and age, heavy menstrual bleeding and in endometriosis patients, endometriosis subtypes. In conclusion, women affected or not by endometriosis are largely willing to donate their menstrual blood for research on endometriosis, dysmenorrhea is not a barrier for donation, and women who use a menstrual cup are the more likely to donate.

The Known, the Unknown and the Future of the Pathophysiology of Endometriosis

Endometriosis is one of the most common causes of chronic pelvic pain and infertility, affecting 10% of women of reproductive age. A delay of up to 9 years is estimated between the onset of symptoms and the diagnosis of endometriosis. Endometriosis is currently defined as the presence of endometrial epithelial and stromal cells at ectopic sites; however, advances in research on endometriosis have some authors believing that endometriosis should be re-defined as "a fibrotic condition in which endometrial stroma and epithelium can be identified". There are several theories on the etiology of the disease, but the origin of endometriosis remains unclear. This review addresses the role of microRNAs (miRNAs), which are naturally occurring post-transcriptional regulatory molecules, in endometriotic lesion development, the inflammatory environment within the peritoneal cavity, including the role that cytokines play during the development of the disease, and how animal models have helped in our understanding of the pathology of this enigmatic disease.

'Listen to women as if they were your most cherished person': Australian women's perspectives on living with the pain of endometriosis: A mixed-methods study

This mixed-methods study used an online cross-sectional survey to explore perspectives of 533 adult Australian women living with endometriosis pain, and their relationship with biopsychosocial factors. Four themes were constructed: The primary theme, 'Stigma and change' reflected women's experience of dismissal, and the wish to reverse the narrative of pain as normal. Some women emphasised self-education and self-advocacy to affect change, reflecting the theme 'self-empowerment'. Participants described the 'debilitating impact' of endometriosis and the enduring difficulty of 'inadequate healthcare', reflecting themes three and four. Analysis indicated type of social support may impact perceived outcomes for endometriosis. Hierarchical regression analyses indicated too few significant relationships between biopsychosocial factors and themes to indicate meaningful patterns without risk of common method variance. Future research should explore the influence of social support and interventions which develop participant autonomy and practitioner competence and knowledge, using disease-specific measures over time.

Three-dimensional model for improvement of endometriosis care (3D-E)

OBJECTIVE

Endometriosis affects approximately 10% of women of reproductive age and leads to significant morbidity and financial burden. Consequently, countries such as France and Germany are formulating strategies to combat endometriosis. In this study, we propose the implementation of our three-dimensional model (3D-E) to raise awareness about endometriosis and enhance timely diagnosis, treatment, and long-term care for affected patients.

METHODS

Based on the adapted Six Sigma Principle and the modified recommendation of Sales et al. for implementing evidence-based findings into a clinical routine, we first conducted a comprehensive investigation to identify risk factors leading to diagnostic delay of endometriosis. After identifying improvable factors, the applicable options were selected due to defined criteria such as integrability in the clinical routine, cost-effectiveness, and evidence-based-principle. Finally, solutions feasible for health care providers were integrated and the 3D-E model was established.

RESULTS

Some of the main risk factors contributing to diagnostic delays are symptoms acceptance and misinterpreted symptoms, especially if presenting to nongynecologists in cases of extragenital endometriosis with atypical presentation. Therefore, we tried to sensitize colleagues (first dimension) with a review paper in Germany's largest medical journal and started an elective for medical students (second dimension) at our university. In order to involve additional health care professionals in endometriosis care (third dimension), we are preparing the concept of the EndoNurse.

CONCLUSION

The 3D-E model is a relatively low-cost, comprehensive, and worldwide adaptable approach for facilitating knowledge transfer, sensitizing health care providers, and improving endometriosis diagnostics and therapy for patients with endometriosis who are in the center of the model.

Postmenopausal endometriosis: a challenging condition beyond menopause

IMPORTANCE AND OBJECTIVE

Postmenopausal endometriosis is a complex condition that challenges the conventional belief that endometriosis resolves with menopause. Despite the cessation of menstruation, a subset of women continues to experience or develop endometriosis-related symptoms during the postmenopausal period. Thus, this review aimed to shed light on postmenopausal endometriosis, exploring its clinical features, diagnostic considerations, management approaches, and the potential impact on women's health.

METHODS

PubMed/Medline, Scopus, and Web of Science databases were used for the research, with only articles in English language, using the following terms: "postmenopausal endometriosis," "menopause," "management," "treatment," and "quality of life," from inception to 2023.

DISCUSSION AND CONCLUSION

The clinical features of postmenopausal endometriosis include persistent or recurrent pelvic pain, dyspareunia, bowel, or urinary symptoms and, occasionally, abnormal vaginal bleeding. The absence of menstrual cycles presents a diagnostic challenge, as the traditional diagnostic criteria for endometriosis rely on menstrual patterns. Visual cues may be less evident, and the symptoms often overlap with other gynecological conditions, necessitating a thorough evaluation to differentiate postmenopausal endometriosis from other potential causes. Management approaches for postmenopausal endometriosis encompass surgical intervention, hormonal therapies, pain management, and individualized care. Postmenopausal endometriosis significantly impacts the quality of life, sexual health, and long-term well-being of women. Understanding the clinical features, diagnostic challenges, and management approaches of postmenopausal endometriosis is crucial for healthcare professionals to provide effective care and to improve the quality of life of women affected by this condition.

Role of Psychosomatic Medicine in Complex Medical Cases: A Case Study of a Patient With Breast Cancer Who Refused Mastectomy

Psychosomatic medicine has been known to play a pivotal role in the management of complex medical cases by providing a bridge between the physical disease and psychological distress. This case study focuses on a 42-year-old Saudi female diagnosed with breast cancer and generalized anxiety disorder. In addition to anxiety, the patient had a history of obsessive-compulsive personality traits, which contributed to her reluctance to undergo mastectomy. Significant challenges and noncompliance with treatment were caused by her unwillingness and inadequate interaction with the medical team. An integrated multidisciplinary strategy including psycho-oncological interventions was necessary because of the complexity of this case. Communication issues were addressed through the concerted efforts of the specialist teams. A comprehensive patient-practitioner understanding was established, which enabled the teams to persuade the patient to undergo surgical intervention. Overcoming her initial resistance, the patient eventually complied with the treatment plan, leading to a successful surgery. Postsurgical evaluations using the Hamilton Anxiety Scale indicated a significant reduction in anxiety levels. This case underscores the critical contribution of psychosomatic medicine to healthcare, especially in challenging situations that demand additional resource allocation, further highlighting the importance of an interdisciplinary approach, efficient communication, and patient-practitioner rapport in healthcare outcomes.

Investigating the medical journey of endometriosis-affected women: Results from a cross-sectional web-based survey (EndoVie) on 1,557 French women

OBJECTIVE

To investigate the medical journey and the quality of life of French endometriosis-affected women, from the onset of the symptoms to the therapeutic management.

STUDY DESIGN

Between January 15th 2020 and February 3rd 2020, a prospective cross-sectional web-based survey was conducted among women diagnosed with endometriosis. The questionnaire included 52 questions distributed in five sections (screening, sociodemographic characteristics, impacts on quality of life, SF36 questionnaire, management of endometriosis and proposals for care improvement).

RESULTS

One thousand five hundred fifty-seven endometriosis-affected women aged of 42±12.8 years answered the questionnaire. On average, 7 years elapsed between the first symptoms (at 23.8 ± 10.2 years) and the diagnosis (31.0 ± 8.9 years). The mean number of symptoms was 4.6 ± 2.3, with 82 % of women experiencing pain scores between 7 and 10/10. Following diagnosis, 66 % women received a medical treatment, mostly hormonal treatments (45 %), with a significant decrease in pain intensity (VAS scores after treatment = 4.9 ± 2.7, p < 0.001). Most women (62 %) had already been operated, among whom 22 % by laparotomy. Finally, patients reported numerous impacts on their daily lives, particularly on the sexual, psychological, and physical fields. The overall mean score of quality of life was 4.3 ± 2.6 /10.

CONCLUSION

This large prospective web-based survey underlines that the journey of women with endometriosis is long and difficult until diagnosis and efficient treatment. It emphasizes the urgent need to reduce the diagnostic delay and thereby the burden of endometriosis on women's lives. Moreover, the creation of referral multidisciplinary centers appears to be crucial to improve the management of the disease.

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.

The feasibility of an anti-inflammatory diet in endometriosis: barriers and facilitators perceived by endometriosis patients

RESEARCH QUESTION

What is the feasibility of an anti-inflammatory diet in women diagnosed with endometriosis?

DESIGN

Qualitative study using semi-structured focus groups and individual interviews among patients with endometriosis. Transcripts of the focus groups and interviews were thematically analysed using ATLAS.ti 9. To identify and structure the ideas and views from the focus groups and interviews, two behavioural change models were used. The Capability Opportunity Motivation Behaviour (COM-B) model and domains of the Theoretical Domains Framework (TDF) helped to identify factors that make adherence to an anti-inflammatory diet more or less feasible for women with endometriosis.

RESULTS

The study population consisted of 23 patients with endometriosis. Numerous perceived barriers and facilitators were identified from all COM-B components and 13 out of 15 TDF domains. Knowledge and social influences were the most prominent TDF domains. Key barriers were eating with others; disbelief in a patients' own capability regarding specific dietary guidelines; concerns about taste; lack of knowledge on how to follow the diet; lack of noticeable beneficial effect; and lack of intention to follow the diet to full extent. Key facilitators were receiving social support; general confidence in a participant's own capabilities; knowing how and why to follow the diet; noticing beneficial effect; and belief that the diet would alleviate symptoms.

CONCLUSION

Provision of knowledge, stimulating social support and enhancing self-efficacy should be emphasized. Overall, an anti-inflammatory diet in endometriosis patients, especially when identified barriers and facilitators are addressed in an intervention, is feasible.

Presence of endometriosis and chronic overlapping pain conditions negatively impacts the pain experience in women with chronic pelvic-abdominal pain: A cross-sectional survey

BACKGROUND

Evidence of overlap between endometriosis and chronic pain conditions is emerging; however, little is known about how the pain experience differs based on the presence or absence of endometriosis.

OBJECTIVES

In a sample of women reporting chronic pelvic-abdominal pain (CPP), the aim of this study was to characterize differences in pain symptomatology between women with and without endometriosis and to examine the influence of chronic overlapping pain conditions (COPCs) on pain among these two groups.

DESIGN

This was a cross-sectional study, based on an online survey.

METHODS

Participants (aged 18+ years) completed a survey collecting pain diagnoses and symptoms assessing pelvic pain severity, pain interference, and pain impact. Independent sample t-tests, chi-square, and multiple linear regression models were employed to analyze group differences in pain symptomatology and COPCs.

RESULTS

Of the 525 respondents with CPP, 25% (n = 133) reported having endometriosis. Women with endometriosis were younger at the onset of pelvic pain, relative to women without endometriosis (p = 0.04). There were no differences in age, race, ethnicity, or duration of pelvic pain between women with and without endometriosis. Women with endometriosis reported higher pelvic pain severity (+0.8, 95% CI = 0.4-1.1), pain interference (+5.9, 95% CI = 2.4-9.3), and pain impact (+1.9, 95% CI = 0.8-2.9). Endometriosis was associated with a higher number of COPCs (p = 0.003), with 25% (n = 33) of women reporting ⩾3 overlapping pain conditions compared with 12% (n = 45) of those without endometriosis. Women with endometriosis had a higher frequency of fibromyalgia (p < 0.001), chronic fatigue syndrome (p < 0.001), and temporomandibular disorder (p = 0.001). The number of COPCs was associated with higher pain severity, interference, and impact, independently of endometriosis.

CONCLUSION

Women with endometriosis experienced higher levels of pain-related burden and COPCs compared with those without endometriosis. Pain intensity, interference, and impact increased with a higher number of pain conditions regardless of endometriosis presence.

Comprehensive endometriosis care: a modern multimodal approach for the treatment of pelvic pain and endometriosis

Endometriosis is a prevalent gynecological disease, leading to chronic pain and inflammation, affecting 1 in 10 individuals presumed female at birth. The diagnostic journey is often arduous, marked by neglect of the right diagnosis and prolonged wait times, significantly compromising the quality of life among those affected. This review provides a nuanced exploration of endometriosis-associated pain management, encompassing medical, surgical, and holistic approaches, all guided by accurate and refined diagnostics. Our paramount goal is to empower physicians as key figures in confronting this intricate challenge with a patient-centric approach, ultimately aiming to improve treatment and quality of life. Acknowledging each patient's unique needs, we emphasize the importance of tailoring a spectrum of options informed by current literature and insights gleaned from our experience in a high-volume tertiary endometriosis center. It is imperative to recognize endometriosis as a complex and chronic disease, often occurring with co-morbid conditions and nuanced complexities, necessitating a long-term personalized multimodal approach for each case. In addition, incorporating principles such as patient autonomy, profound respect for diverse experiences, and practical education on treatment choices is pivotal in enhancing treatment outcomes and overall patient satisfaction.

Sphingosine-1-phosphate receptor 3 is a non-hormonal target to counteract endometriosis-associated fibrosis

OBJECTIVE

To study the molecular mechanisms responsible for fibrosis in endometriosis by investigating whether the protein expression levels of sphingosine-1-phosphate receptor 3 (S1PR3), one of the five specific receptors of the bioactive sphingolipid sphingosine-1-phosphate (S1P), correlate with fibrosis extent in endometriotic lesions and which are the cellular mechanisms involved in this process.

DESIGN

Case-control laboratory study and cultured endometriotic cells.

SETTING

University research institute and university hospital.

PATIENT(S)

A total of 33 women, with and without endometriosis, were included in the study.

INTERVENTIONS(S)

Endometriotic lesions were obtained from women with endometriosis (ovarian endometrioma, n = 8; deep infiltrating endometriosis, n = 15; [urological n = 5, gastrointestinal n = 6, and posterior n = 4]) and control endometrium from healthy women, n = 10, by means of laparoscopic and hysteroscopic surgery. The expression of S1PR3 was evaluated using immunohistochemistry and the extent of fibrosis was assessed using Masson's trichrome staining. Human-cultured epithelial endometriotic 12Z cells were used to evaluate the mechanisms involved in the profibrotic effect of S1PR3 activation.

MAIN OUTCOME MEASURE(S)

The expression of S1PR3 in endometriotic lesions is positively correlated with endometriosis-associated fibrosis. In addition, S1P induced epithelial-mesenchymal transition (EMT) and fibrosis in epithelial endometriotic cells. Using RNA interference and pharmacological approaches, the profibrotic effect of S1P was shown to rely on S1PR3, thus unveiling the molecular mechanism implicated in the profibrotic action of the bioactive sphingolipid.

RESULT(S)

The protein expression levels of S1PR3 were significantly augmented in the glandular sections of endometrioma and deep infiltrating endometriosis of different localizations with respect to the control endometrium and positively correlated with the extent of fibrosis. Sphingosine-1-phosphate was shown to have a crucial role in the onset of fibrosis in epithelial endometriotic cells, stimulating the expression of EMT and fibrotic markers. Genetic approaches have highlighted that S1PR3 mediates the fibrotic effect of S1P. Downstream of S1PR3, ezrin and extracellular-signal-regulated kinases 1 and 2 signaling were found to be critically implicated in the EMT and fibrosis elicited by S1P.

CONCLUSION(S)

Sphingosine-1-phosphate receptor 3 may represent a possible innovative pharmacological target for endometriosis.

The deviations of CD4 + T cells during peripheral blood and peritoneal fluid of endometriosis: a systematic review and meta-analysis

OBJECTIVE

To assess whether endometriosis (EMs) was related to systematic and/or local deviations of cluster of differentiation (CD)4 + T cells.

METHODS

Until November 2022, we enrolled a total of 1363 EMs and 1564 healthy women from 32 studies who met the inclusion criteria.

RESULTS

After systematically retrieving the literature, we identified 1086 citations and 32 case-control studies were enrolled. Cumulative results suggested that there were insignificant deviations of CD4 + T cells during peripheral blood (PB) between EMs and healthy women (RR: - 0.83, I2 = 99%, p = 0.65), also no statistically significant difference was found between mild and severe EMs (RR: 3.19, I2 = 94%, p = 0.19). We also found insignificant deviations of CD4 + /CD8 + during PB between EMs and healthy women (RR: 0.09, I2 = 99%, p = 0.39), and between mild and severe EMs (RR: - 0.16, I2 = 99%, p = 0.29). The results might suggest that there was no significant correlation between EMs and systematic deviations of CD4 + T cells. When it came to local deviation during peritoneal fluid (PF), the polled results suggested that the frequency of CD4 + T cells during EMs was significantly lower than healthy women (RR: - 5.38, I2 = 93%, p = 0.01), and the ratio of CD4 + /CD8 + during EMs was significantly lower than healthy women (RR: - 0.13, I2 = 0%, p < 0.0001). However, there were insignificant deviations of CD4 + during PF between mild and severe EMs (RR: 1.65, I2 = 53%, p = 0.15), also there was an insignificant difference of CD4 + /CD8 + between mild and severe EMs (RR: - 0.09, I2 = 14%, p = 0.19). EMs might be closely related to local deviations of CD4 + T cells.

CONCLUSION

There was no obvious correlation between EMs and systematic deviations of CD4 + T cells, EMs might be closely related to local deviations of CD4 + T cells. Further study on the functional deviations and subpopulation distribution of CD4 + T cells is urgently needed.

Endometriosis and sexual disorders: the effect of surgical and medical treatment, a multicentre cross-sectional study

Background

Sexual health is a major concern in women with endometriosis, however only a few controlled studies have examined this with validated instruments. The effect of hormonal treatments on sexual function in endometriosis is also an underrated topic. The aim of this study was to investigate sexual function of patients with endometriosis by a specific tool to better evaluate their sexual function (including different domains), and the influence of hormonal treatment or surgery on these parameters.

Methods

An observational, cross-sectional, multicentre study was conducted in a group (n=194) of sexually active, women aged 25-45 years old, with surgical or ultrasonographic diagnosis of endometriosis, referred to the Endometriosis Center of Careggi University Hospital or Negrar di Valpolicella. Sexual function was assessed by administering the Female Sexual Function Index (FSFI), which assesses the domains of desire, arousal, lubrication, orgasm, satisfaction and pain. FSFI scores were compared to those of a control group (n=58) and according to the treatment received by patients with endometriosis.

Results

Ovarian endometriosis was present in 50 patients (25.8%), deep infiltrating endometriosis in 65 patients (33.5%) and both in 79 patients (40.7%). Adenomyosis coexisted in 102 patients (52.6%). Women with endometriosis reported a mean total FSFI score of 18.3 [4.2-25.8] (< 26.55), indicating female sexual dysfunction (FSD) in all patients. At multivariate analysis, after adjusting for confounders (BMI and hormonal therapy), women with endometriosis presented significantly lower scores than controls in all the FSFI (p<0.001). Patients with endometriosis under hormonal treatments (n=124; 64%), regardless of the type, had significantly lower scores in all FSFI subscales and total score, even after adjusting for confounders-age, BMI and history of surgery.

Conclusions

Patients with endometriosis are at risk for FSD, encompassing not only dyspareunia, but all domains of sexual function. Hormonal treatments do not result in improvement in sexual symptoms.

Efficacy of an environmental enrichment intervention for endometriosis: a pilot study

Introduction

We have previously shown that Environmental Enrichment (EE), a multi-modal psychosocial intervention consisting of increased social interaction, novelty, and open spaces, improved disease presentation, anxiety, and immune-related disturbances in the rat model of endometriosis. However, there is a knowledge gap regarding the effects of EE interventions in patients with this painful, inflammatory chronic disease.

Aim

To adapt and test the efficacy of an EE intervention on pelvic pain, mental health, perceived stress, quality of life, and systemic inflammation in endometriosis patients through a randomized clinical trial (RCT).

Materials and methods

A multidisciplinary team with expertise in physiology, neuroscience, psychology, and women's health adapted and implemented a two-arm RCT comparing an EE intervention with a wait-list control group. Six EE modules administered on alternate weeks were provided to patients in the intervention (N = 29); controls received education only. Survey data and biospecimens were collected at baseline, end-of-study, and 3-months post-intervention to assess pain (Brief Pain Inventory, BPI), endometriosis-related quality of life-QoL (Endometriosis Health Profile-30, EHP30), anxiety (Generalized Anxiety Disorder 7, GAD7), depression (Patient Health Questionnaire for Depression 8, PHQ8), pain catastrophizing (Pain Catastrophizing Score, PCS), stress (Perceived Stress Scale-14, PSS14), and saliva cortisol levels (AM, PM).

Results

Compared to the wait-list controls, participants in the EE intervention showed significantly decreased GAD-7 scores at the end of the intervention and 3-month follow-up. Depression, perceived stress, and QoL improved at the 3-month follow-up compared to baseline. While pain levels did not improve, they significantly correlated with anxiety, depression, QoL and pain catastrophizing scores.

Conclusion

This pilot RCT demonstrated significant improvements in anxiety and depressive symptoms, QoL, and perceived stress, supporting enriched environments as an integrative psychosocial intervention to be used as adjuvant to the standard of care for endometriosis pain.
