The Burden of Endometriosis on Women's Lifespan: A Narrative Overview on Quality of Life and Psychosocial Wellbeing

Women's Self-Management of Dyspareunia Associated With Endometriosis: A Qualitative Study

Given the limitations of medical treatment for endometriosis, self-management is a critical component of symptom management, and providing patients with information and education is a necessary complement to medical interventions. Though 50 to 70% of people with endometriosis experience dyspareunia (painful sex), there is limited knowledge of self-management specific to painful sex. A comprehensive understanding of the self-management strategies used is foundational to developing supportive care interventions that help ease pain and related psychosocial sequelae. The objective was to describe people's experiences of navigating endometriosis-associated painful sex and developing self-management strategies. We analyzed interview data from 20 women using constant comparative and thematic analysis techniques, guided by qualitative interpretive description methodology. Participants (age range 18-44 years) all identified as women and were predominately Caucasian (90%) and heterosexual (80%). Throughout their lives, the women appeared to gradually develop self-management strategies while navigating painful sexual experiences. This complex journey encompassed four phases: 1) viewing painful sex as normal, 2) experiencing evolving thoughts and emotions, 3) coming to understand painful sex and seeking help, and 4) learning strategies to navigate painful sex, these include preparing mentally and physically for sex and communicating with intimate partner(s). Women in this study developed self-management strategies over time through engagement with others who understood their challenges. Future research is warranted regarding initiatives to counter the normalization of painful sex, develop and disseminate patient-facing information, provide education specific to dyspareunia, improve access to multidisciplinary care, facilitate social connections and support, and enhance communication with intimate partners. PERSPECTIVE: In this paper, we report on the experiences of women with endometriosis-associated painful sex and their self-management strategies. Clinicians may be interested in a qualitative exploration of endometriosis-associated painful sex as they seek to further understand their patient's experiences and what strategies can be implemented to alleviate dyspareunia. DATA AVAILABILITY: The data sets generated during and/or analyzed during the current study are not publicly available as participants did not consent to making their data publicly available but are available from the corresponding author on reasonable request.

Investigating the efficacy of transcranial direct current stimulation on chronic pain management in endometriosis patients: A randomized controlled trial protocol

INTRODUCTION

Similar to chronic pain conditions, individuals with endometriosis can be affected by central sensitization syndrome (CSS), which is characterized by a loss of analgesia and central amplification of pain. Transcranial direct current stimulation (tDCS) has shown potential as an effective intervention to improve pain generated by other chronic pain conditions impacted by CSS, such as fibromyalgia and chronic pelvic issues. This study aims to evaluate the effectiveness of tDCS on pain, fatigue, and quality of life among patients affected by endometriosis.

METHODS

This is a single-center, parallel, double-blinded, randomized, controlled clinical trial protocol study. We aim to recruit 40 participants affected by endometriosis (active group, n = 20; sham group, n = 20). Anodal tDCS will be delivered at an intensity of 2mA, applied over the primary motor cortex for 20 minutes per day for 10 consecutive days. There will be four assessment times: 1 week before beginning the intervention; on the 10th day following the last tDCS session; and 1 and 2 months after the last tDCS session. Pain evaluated by the algometry will be the primary outcome. Pain intensity, quality of life, fatigue, and global perception of change will be the secondary outcomes. We will calculate the effects of the active versus sham stimulation on primary and secondary outcomes by using generalized estimated equations or mixed model analysis. The effect size calculation will represent the effect measure. We expect that only the active group show reductions in pain, fatigue, and quality of life. The results of this trial will produce an important first step in providing evidence on the effectiveness of neuromodulation for the management of pain and will provide data to support new studies on tDCS.

Holistic approach to care for patients with endometriosis

PURPOSE OF REVIEW

Endometriosis is a chronic, often debilitating, disease which is typically managed with surgery and hormonal medications. However, many patients feel they lack agency when managing endometriosis symptoms. The purpose of this review is to discuss the mental and physical management strategies, the long-term health consequences, and the role of a multidisciplinary team in the treatment of endometriosis.

RECENT FINDINGS

Evidence is becoming more robust regarding the role of complementary care and physical activity in the management of endometriosis. Health risks such as infertility are well known and newer evidence is evolving regarding perinatal and cardiovascular health risks. There are also trends towards multiple specialist involvement in the care of endometriosis and the benefit of interdisciplinary collaboration.

SUMMARY

Endometriosis is a frequently recurrent condition requiring not only meticulous medical and surgical care, but also coordinated longitudinal disease management and impact mitigation. Gynecologists should be aware of the short-term and long-term implications of the disease to empower patients on the management of their overall health.

Proteomics approach to discovering non-invasive diagnostic biomarkers and understanding the pathogenesis of endometriosis: a systematic review and meta-analysis

BACKGROUND

Endometriosis is one of the most common gynaecological diseases, yet it lacks efficient biomarkers for early detection and unravels disease mechanisms. Proteomic profiling has revealed diverse patterns of protein changes in various clinical samples. Integrating and systematically analysing proteomics data can facilitate the development of biomarkers, expediting diagnosis and providing insights for potential clinical and therapeutic applications. Hence, this systematic review and meta-analysis aimed to explore potential non-invasive diagnostic biomarkers in various biological samples and therapeutic targets for endometriosis.

METHODS

Online databases, including Scopus, PubMed, Web of Science, MEDLINE, Embase via Ovid, and Google Scholar, were searched using MeSH terms. Two independent authors screened the articles, extracted the data, and assessed the methodological quality of the included studies. GO and KEGG analyses were performed to identify the pathways that were significantly enriched. Protein‑protein interaction and hub gene selection analyses were also conducted to identify biomarker networks for endometriosis.

RESULTS

Twenty-six observational studies with a total of 2,486 participants were included. A total of 644 differentially expressed proteins (180 upregulated and 464 downregulated) were identified from 9 studies. Proteins in peripheral blood exhibited a sensitivity and specificity of 38-100% and 59-99%, respectively, for detecting endometriosis, while proteins in urine had a sensitivity of 58-91% and specificity of 76-93%. Alpha-1-antitrypsin, albumin, and vitamin D binding proteins were significantly DEPs in both serum and urine. Complement C3 is commonly expressed in serum, menstrual blood, and cervical mucus. Additionally, S100-A8 is commonly expressed in both menstrual blood and cervical mucus. Haptoglobin is commonly detected in both serum and plasma, whereas cathepsin G is found in urine, serum, and plasma. GO and KEGG enrichment analyses revealed that proteoglycans in cancer pathways, which regulate cell-to-cell interactions, modulate the extracellular matrix, and promote the proliferation and invasion of endometrial cells, are commonly enriched in serum and urine.

CONCLUSION

This comprehensive study revealed potential proteomes that were significantly differentially expressed in women with endometriosis utilizing various non-invasive clinical samples. Exploring common differentially expressed proteins in various biological samples provides insights into the diagnosis and pathophysiology of endometriosis, as well as potential clinical and therapeutic applications.

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: A Comprehensive Analysis of the Pathophysiology, Treatment, and Nutritional Aspects, and Its Repercussions on the Quality of Life of Patients

Endometriosis is a chronic proinflammatory pathology characterized by the growth of tissue similar to the endometrium outside the uterus, affecting approximately 5 to 15% of women worldwide. Suffering from endometriosis entails a complex pathophysiological process, significantly impacting the quality of life and reproductive function of affected women; therefore, it must be addressed in a personalized and comprehensive manner, as its management requires a multidisciplinary approach. This article aims to conduct a comprehensive literature review of endometriosis, not only as a pathophysiological condition but also as a significant factor impacting the social, nutritional, and mental well-being of those who experience it. Emphasis is placed on the importance of understanding and assessing the impact of the pathology to provide a better and more comprehensive approach, integrating various alternatives and strategic treatments for the factors involved in its development. The aim is to provide a complete overview of endometriosis, from its pathophysiology to its impact on the quality of life of patients, as well as a review of current treatment options, both pharmacological and alternative, in order to broaden the perspective on the pathology to improve the care of patients with this disease.

The coagulation status in women of endometriosis with stage IV

BACKGROUND

Endometriosis is considered as a systemic disease with the presence of proinflammatory cytokines in the circulation, which drives hypercoagulable state of endometriosis. Currently, endometriosis is classified into four stages: I (minimal), II (mild), III (moderate) and IV (severe). The aim of this study is to investigate the correlations between inflammatory markers and coagulation factors in patients diagnosed of endometriosis with stage IV.

METHODS

This retrospective case-control study included 171 endometriosis patients with stage IV and 184 controls. Continuous data were expressed by mean ± standard deviation. Mann-Whitney U and χ2 tests were used to compare the medians and frequencies among the groups. Spearman analysis was conducted to determine the correlation among the measured parameters. The diagnostic values of the parameters differentiating endometriomas were tested by receiver operating characteristic (ROC) curve.

RESULTS

The time of activated partial thromboplastin time (APTT) was decreased and the concentration of fibrinogen (FIB) and neutrophil-to-lymphocyte ratio (NLR) were increased in women of endometriosis with stage IV. The APTT were negatively correlated with NLR while the concentrations of FIB were positively correlated with NLR. The ROC analysis showed that the Area under the curve (AUC) of FIB was 0.766 (95% confidence interval:0.717-0.814) with sensitivity and specificity reaching 86.5 and 60.9%, respectively. The AUC of CA125 and CA199 was 0.638 (95% confidence interval: 0.578-0.697), 0.71 (95% confidence interval: 0.656-0.763) with sensitivity and specificity reaching 40.9 and 91.8%, 80.7 and 56.5% respectively. The combination of these factors showed the highest AUC of 0.895 (0.862-0.927) with sensitivity of 88.9% and specificity of 77.7%.

CONCLUSION

In the present study, we found that inflammatory factors showed significant correlation with APTT or FIB in endometriosis with stage IV. Moreover, the coagulation factors combined with CA125 and CA199 were more reliable for identifying the endometriosis with stage IV.

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.

Depressive symptoms of older adults with chronic diseases: the mediating roles of activities of daily living and economic burden of diseases

Objective

To explore the mediating roles of activities of daily living (ADL) and economic burden of diseases in the relationship between chronic diseases and depressive symptoms of older adults.

Methods

The data were sourced from China Health and Retirement Longitudinal Study (CHARLS). The number of chronic diseases, ADL, out-of-pocket medical expenses and the Center for Epidemiological Studies Depression Scale (CES-D) were selected as measuring indexes. Mediation analysis was conducted to explore the potential mediating roles of ADL and economic burden of diseases in the association between chronic diseases and depressive symptoms.

Results

The number of chronic diseases, ADL, economic burden of diseases and depressive symptoms of older adults were significantly correlated with each other. ADL and economic burden of diseases individually mediated the relationship between the number of chronic diseases and depressive symptoms, accounting for 31.460% and 5.471% of the total effect, respectively. Additionally, ADL and economic burden of diseases demonstrated a chain mediating effect in this relationship, contributing to 0.759% of the total effect.

Conclusion

The chain-mediated model effectively elucidated the mediating roles of ADL and economic burden of diseases in the association between chronic diseases and depressive symptoms among older adults. The study underscores the need for policymakers to focus attentively on the mental health of older adults with chronic diseases. Enhancing the capacity for ADL and strengthening social security to mitigate the economic burden of diseases are recommended strategies to alleviate depressive symptoms in older adults.

Surgical and Percutaneous Image-guided Therapies of Abdominal Wall Endometriosis: a Systematic Review of Current Evidence

OBJECTIVE

Despite various surgical and non-surgical strategies for abdominal wall endometriosis, the lack of definitive guidance on optimal treatment choice leads to clinical uncertainty. This review scrutinizes the safety and efficacy of abdominal wall endometriosis treatments to aid in decision-making.

DATA SOURCES

We performed a systematic literature review of PubMed, Embase and Cochrane Library databases from 1947 until December 2023.

METHODS OF STUDY SELECTION

A comprehensive literature search identified studies that assessed both surgical and nonsurgical interventions, including high-intensity focused ultrasound (HIFU), cryoablation, radiofrequency ablation (RFA), and microwave ablation (MWA). This review is registered in NIHR-PROSPERO (CRD 42023494969). Local tumor control (LTC), local pain relief (LPR) and adverse events (AE) were recorded.

TABULATION, INTEGRATION, AND RESULTS

This review included 51 articles among 831 identified. All study designs were considered eligible for inclusion. A total of 2,674 patients are included: 2,219 patients (83%) undergoing surgery, and 455 (17%) undergoing percutaneous interventions (342 HIFU, 103 cryoablation, 1 RFA, 9 MWA). Follow-up length was 18 months in median, ranging from 1 to 235 months. Overall LTC rates ranged from 86% to 100%. Surgical interventions consistently demonstrated the highest rate of LTC with a median rate of 100%, and LPR with a median rate of 98.2% (95% confidence interval [CI]: 93.9-97.7). HIFU showed median LTC and LPR rates, respectively of 95.65% (95% CI, 87.7-99.9) and 76.1% (95% CI, 61.8-90.4); and cryoablation of 85.7% (95% CI, 66.0-99.9) and 79.2% (95% CI, 67.4-91.03). Minor AE were reported after surgery in 17.5% of patients (225/1284) including 15.9% (199/1284) of mesh implantation; 76.4% (239/313) after HIFU; and 8.7 % (9/103) after cryoablation. Severe AE were reported in 25 patients in the surgery group and 1 in the percutaneous group.

CONCLUSION

The safety profile and efficacy of nonsurgical interventions support their clinical utility for management of abdominal wall endometriosis.

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.

Immune Checkpoints in Endometriosis-A New Insight in the Pathogenesis

Endometriosis (EMS) is an oestrogen-dependent, chronic disease affecting women of a reproductive age. One of the important factors involved in the development of this disease is the complex disorders associated with the functioning of the immune system. Recent evidence has shown that EMS development is associated with changes in systemic and local immunity, including functional disturbances of effector and antigen-presenting cells. One of the reasons for immune imbalance can be the improper expression of immune checkpoints (ICPs). ICPs and their ligands are responsible for maintaining self-tolerance and the modulation of the initiation, duration, and magnitude of the immune response of effector cells in normal tissues to avoid tissue damage. Considering the complex nature of co-stimulatory or co-inhibitory ICPs and the signalling between effector cells and APCs, we hypothesise that changes in cells' activity caused by ICPs may lead to serious immune system disturbances in patients with endometriosis. Moreover, both upregulation and downregulation in the expression of ICPs may be implicated in this process, including the reduced activity of effector cells against endometrial implants and disturbances in the antigen-presenting process. In this narrative review, we discuss, for the first time, key findings from the emerging literature, describing the associations between ICPs and their possible implication in the pathogenesis of endometriosis.

Assessment of quality of life, psychological aspects, and sexual function of women with endometriosis according to pain and infertility: a cross sectional study

PURPOSE

To evaluate the quality of life, sexual function, anxiety, and depression of women with endometriosis according to pain symptoms and infertility.

METHODS

This cross-sectional multicenter study included 229 women with endometriosis followed up at a tertiary hospital in Campinas, a tertiary hospital in São Paulo, and a reproductive medicine clinic in Campinas from 2018 to 2021. The women were divided into four groups according to the presence of pain symptoms and infertility. The Endometriosis Health Profile Questionnaire, Female Sexual Function Index, Beck Depression Inventory, and Beck Anxiety Index were applied to assess quality of life, sexual function, depression, and anxiety of women with endometriosis.

RESULTS

The women were grouped as follows: group 1 (45 women without infertility and without pain), group 2 (73 women without infertility and with pain), group 3 (49 women with infertility and without pain), and group 4 (62 women with infertility and pain). Of the women with infertility, the majority had primary infertility. Most women had deep endometriosis (p = 0.608). Women with pain had higher anxiety and depression scores and worse quality of life than women without pain (p < 0.001). Regarding sexual function, all the groups were at risk for sexual dysfunction (p = 0.671). The group of women with pain and infertility have worse anxiety scores (25.31 ± 15.96) and depression (18.81 ± 11.16) than the other groups.

CONCLUSION

Pain symptoms worsen anxiety, depression, and quality of life of women with endometriosis and when associated with infertility, greater impairment of psychological aspects may occur.

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

OBJECTIVE

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

DATA SOURCES

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

METHODS OF STUDY SELECTION

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

TABULATION, INTEGRATION, AND RESULTS

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

CONCLUSION

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

Post-marketing safety concerns with elagolix: a disproportionality analysis of the FDA adverse event reporting system

OBJECTIVE

Elagolix is approved for the treatment of moderate-to-severe pain associated with endometriosis. However, the long-term safety of elagolix in a large sample of real-world patients is unknown.

METHODS

The U.S. Food and Drug Administration Adverse Event Reporting System (FAERS) reports were collected and analyzed from January 2019 to June 2023. Disproportionality analyses, including the reporting odds ratio (ROR), the proportional reporting ratio (PRR), the Bayesian confidence propagation neural network (BCPNN), and the multi-item gamma Poisson shrinker (MGPS) algorithms, were employed in data mining to quantify the signals of elagolix-related adverse events (AEs).

RESULTS

After removing the non-drug-related AE signals, we detected several AE signals such as hot flushes, bone pain, suicidal ideation, depression, and increased liver enzymes, which were known during the clinical trial phase. In addition to this, we detected several unexpected important AEs that were not mentioned in the drug insert, including cystitis interstitial, parosmia, and epiploic appendagitis. The median onset time of elagolix-associated AEs was 28.5 days.

CONCLUSION

Our study provides a comprehensive picture of the safety of elagolix in the post-marketing setting, while also identifying potential new AE signals. These findings emphasize the importance of continued monitoring of the potential risks of elagolix.

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.

An evaluation of sexual function and health-related quality of life following laparoscopic surgery in individuals living with endometriosis

STUDY QUESTION

What is the relationship between sexual function, health-related quality of life (HRQoL), and laparoscopic surgery in individuals living with endometriosis?

SUMMARY ANSWER

A higher number of laparoscopic surgeries is significantly associated with poorer HRQoL and greater levels of sexual dysfunction in individuals with endometriosis.

WHAT IS KNOWN ALREADY

Prior research indicates that endometriosis is associated with lowered HRQoL and sexual function and that these outcomes are influenced by endometriosis-related symptom profiles, medical, and surgical management. A limited number of studies have examined changes in sexual function in individuals with endometriosis following laparoscopic surgery or following repeated surgeries.

STUDY DESIGN, SIZE, DURATION

A cross-sectional community-based online survey was used to examine the relationships between sexual function, HRQoL, and laparoscopic surgery (n = 210).

PARTICIPANTS/MATERIALS, SETTING, METHODS

Individuals with a self-reported diagnosis of endometriosis were recruited via online advertising through social media and gynaecology clinics. Endometriosis-specific data (e.g. diagnostic delay, symptom experience) was collected in addition to engagement with laparoscopic surgery, level of HRQoL (EuroQol-5 Dimension: EQ-5D-5L), and sexual function (Female Sexual Function Index: FSFI). Bivariate correlational analyses and hierarchical multiple regression were used to determine the associations between the variables of interest.

MAIN RESULTS AND THE ROLE OF CHANCE

Individuals with endometriosis have substantially poorer HRQoL in comparison to Australian normative samples, with greater levels of endometriosis-related symptom burden, distress, and pain significantly associated with lower levels of HRQoL. The mean FSFI score was suggestive of clinically significant female sexual dysfunction, with the lowest level of function noted in the domain of sexual pain and the highest level of function noted in the sexual satisfaction domain. A greater number of laparoscopic surgeries was significantly associated with poorer overall HRQoL and greater levels of sexual dysfunction.

LIMITATIONS, REASONS FOR CAUTION

The cross-sectional nature of the data precludes direct findings of causality and further longitudinal research is recommended. The information pertaining to engagement in laparoscopic surgery was self-report in nature and was not medically verified.

WIDER IMPLICATIONS OF THE FINDINGS

The study's findings highlight the pervasive impact of endometriosis on all domains of living, emphasizing the need to extend treatment planning beyond that of physical pain management alone. Early referral for assessment and management of sexual wellbeing is recommended prior to, and post-surgical intervention, with a focus on maintaining post-surgical changes, potentially reducing the need for multiple surgeries.

STUDY FUNDING, COMPETING INTEREST(S)

The study was not associated with research funding. Author CN reports grant funding from the Australian Government and Medical Research Future Fund (MRFF) and was a previous employee of CSL Vifor (formerly Vifor Pharma Pty Ltd).

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.

Risk of Iron Deficiency in Women With Endometriosis: A Population-Based Prospective Cohort Study

BACKGROUND

Endometriosis may be linked to the risk of iron deficiency through chronic systemic inflammation or heavy menstrual bleeding. No longitudinal studies, however, have examined the relationship between endometriosis and the risk of iron deficiency.

METHODS

This study included 3,294 participants born from 1973 to 1978 and followed as part of the Australian Longitudinal Study on Women's Health from 2000 to 2018. Participants with endometriosis were identified using self-reported longitudinal surveys linked to administrative health records. During each survey, participants were also asked to report the diagnosis of iron deficiency, and we validated diagnoses using an administrative health database. Generalized estimating equations for binary responses with an autoregressive correlation matrix were used to examine the association between endometriosis and the risk of iron deficiency over the seven time points.

FINDINGS

We found that women with endometriosis had a significantly higher risk of iron deficiency than those without endometriosis after adjusting for sociodemographic, lifestyle, reproductive, and nutrition factors (adjusted odds ratio [aOR] = 1.46; 95% confidence interval [CI] [1.29, 1.66]; p < .0001). Women with a surgically confirmed diagnosis and those with clinically suspected endometriosis had a higher risk of iron deficiency (aOR = 1.38; 95% CI [1.17, 1.64] and aOR = 1.53; 95% CI [1.30, 1.81]), respectively. These associations, however, were slightly attenuated (by 8%) when adjusted for the presence of heavy menstrual bleeding.

CONCLUSIONS

Women with endometriosis are at a higher risk of developing iron deficiency than those without endometriosis. The findings suggest that iron deficiency should be concomitantly addressed during initial diagnosis and successive management of endometriosis.

Are women with endometriosis more likely to experience reduced physical performance compared to women without the condition?

Background

Endometriosis is a condition of the female reproductive system associated with pelvic pain. Chronic pain can affect physical performance by limiting the functional activities, thus, it is hypothesized that women with endometriosis may also present decreased functional capacity, decreased strength, and mobility. The objective of this study is to compare physical performance in women with and without endometriosis.

Methods

This is a cross-sectional study composed of 115 women equally divided into two groups: the endometriosis group (EG), composed of women with a confirmed diagnosis of the disease by magnetic resonance imaging, and the comparator group (CG), consisting of women without suspicion of the disease. Physical performance (dependent variable) was assessed using hand dynamometry, the 6-min walk test (6MWT), gait speed, and the chair stands test. CG participants performed the tests during the luteal phase of the menstrual cycle. Descriptive statistics, unpaired t-tests, and chi-square tests were used to describe and compare the groups. Multiple linear regression tested the associations adjusted for covariates (age, income, education, age at menarche, and body mass index).

Results

The EG had worse gait speed (mean difference: -0.11; 95% CI: [-0.18 to -0.04]), weaker grip strength (mean difference: -3.32; 95% CI: [-5.30 to -1.33]), shorter distance covered in the 6MWT (mean difference: -83.46; 95% CI: [-121.38 to -45.53]), and a lower number of repetitions in the chair stands test (mean difference: -8.44; 95% CI: [-10.64 to -6.25]) than the CG, even after adjusting for covariates.

Conclusion

Grip strength, lower limb strength, mobility, and functional capacity were worse in women diagnosed with endometriosis. Women with endometriosis should be encouraged to engage in physical exercise, adopt healthy lifestyle habits, and participate in rehabilitation activities to control pain, with the aim of reducing functional impairments.

Circulating microRNAs as Non-Invasive Biomarkers in Endometriosis Diagnosis-A Systematic Review

The aim of this systematic review is to assess the power of circulating miRNAs as biomarkers as a diagnostic tool in endometriosis. In endometriosis-suspected women with uncertain imaging, the only way to confirm or exclude endometriosis with certainty is currently laparoscopy. This creates a need for non-invasive diagnostics. We searched the literature through the PubMed database using the Mesh terms 'endometriosis' and 'miRNAs'. Some, but limited, overlap was found between the 32 articles included, with a total of 20 miRNAs reported as dysregulated in endometriosis in two or more studies. MiR-17-5p was reported as dysregulated in six studies, followed by miR-451a and let-7b-5p in four studies and miR-20a-5p, miR-143-3p, miR-199a-5p and miR-3613-5p in three studies. Furthermore, a possible impact of the menstrual phase on miRNA expression was noted in five studies, while no influence of hormonal intake was observed in any included study. The modest reproducibility between studies may be attributable to biological variability as well as to the lack of universal protocols, resulting in pre- and analytical variability. Despite the identification of several suitable candidate biomarkers among the miRNAs, the need for high-quality studies with larger and well-defined population cohorts and the use of standardized protocols lingers.

The etiology of endometriosis: Is Fusobacterium to blame?

A recent cohort study has highlighted the potential role of Fusobacterium in causing endometriosis which, after further evidence, might call for a modified treatment plan.

Systematic review and meta-analysis on the effect of adjuvant gonadotropin-releasing hormone agonist (GnRH-a) on pregnancy outcomes in women with endometriosis following conservative surgery

BACKGROUND

Endometriosis frequently results in pain and infertility. While conservative surgery offers some relief, it often falls short of ensuring satisfactory pregnancy outcomes. Adjuvant GnRH-a is administered post-surgery to mitigate recurrence; however, its impact on pregnancy outcomes remains debated. This study endeavors to assess the efficacy of adjuvant GnRH-a in enhancing pregnancy outcomes post-conservative surgery in endometriosis patients.

METHODS

Databases including PubMed, Embase, the Cochrane Library, Medline (Ovid), Web of Science, and Scopus were rigorously searched up to 02 August 2023, without linguistic constraints. Identified articles were screened using strict inclusion and exclusion criteria. Evaluated outcomes encompassed pregnancy rate, live birth rate, miscarriage rate, ectopic pregnancy rate, multiple pregnancy rate, mean postoperative pregnancy interval, recurrence rate, and adverse reaction rate. The Cochrane risk of bias tool and the Jadad score evaluated the included studies' quality. Subgroup and sensitivity analysis were implemented to analyze the pooled results. A meta-analysis model expressed results as standardized mean difference (SMD) and Risk ratio (RR).

RESULTS

A total of 17 studies about 2485 patients were assimilated. Meta-analysis revealed that post-surgery, the GnRH-a cohort experienced a marginally elevated pregnancy rate (RR = 1.20, 95% CI = 1.02-1.41; P = 0.03) and a reduced mean time to conceive (RR = -1.17, 95% CI = -1.70- -0.64; P < 0.0001). Contrarily, other evaluated outcomes did not exhibit notable statistical differences.

CONCLUSIONS

Incorporating adjuvant GnRH-a following conservative surgery may be deemed beneficial for women with endometriosis, especially before Assisted Reproductive Technology (ART). Nonetheless, owing to pronounced heterogeneity, subsequent research is warranted to substantiate these potential advantages conclusively.

Changes in lower urinary tract function after minimally invasive nerve-sparing for complete excision of endometriosis: An observational study

OBJECTIVES

The objective of this paper is to evaluate changes in lower urinary tract symptoms (LUTS), severity of pain and urodynamic parameters after minimally invasive nerve-sparing surgery for patients with endometriosis.

METHODS

We analyzed 143 patients undergoing minimally invasive nerve-sparing surgery for endometriosis excision (laparoscopy/robot-assisted). The endometriosis was confirmed by preoperative clinical evaluation, magnetic resonance imaging (MRI) showing at least one lesion deeper than 5 mm, and histological confirmation after laparoscopy. We evaluated three points prior and after surgery: LUTS parameters according to the International Urogynecological Association; urodynamic measures of storage and voiding and the severity of the dyspareunia, dyschezia and dysmenorrhea assessed on a self-reported 11-point numeric rating scale. The Wilcoxon signed rank and McNemar tests were used for statistical analyses (p < 0.05).

RESULTS

We observed significant improvements in LUTS after the surgery with postoperative symptom-free probabilities in urgency (64.5%), daytime frequency (38.5%), and dysuria (87.1%). However, slow stream prevalence increased significantly postsurgery (p = 0.022), with a 20.5% risk of asymptomatic patients developing this symptom. Urodynamic responses varied; for instance, maximum cystometric capacity improved significantly (p = 0.004), while postvoiding residual worsened (p = 0.006). Significant worsening in postvoiding residual occurred in women with normal preoperative values (p = 0.002), with a 17.7% risk of normal values becoming abnormal. Compliance or maximum cystometric capacity not considered normal preoperatively showed significant improvements (p < 0.001), but the risk of normal values becoming abnormal after surgery was 14.5%.

CONCLUSION

The minimally invasive nerve-sparing surgery for endometriosis excision shows improvement in lower urinary tract symptoms, urodynamics parameters and severity of pain. The majority of patients became asymptomatic in the postoperative period. When compared to the benefits of the patients' surgical treatment, particularly when considering the reduction of pain, the risks of the lower urinary tract treatment seem to be acceptable. The surgical intervention seems to be a safe alternative in patients with endometriosis, although studies with larger samples are needed to confirm these findings.

Pyroptotic T cell-derived active IL-16 has a driving function in ovarian endometriosis development

Endometriosis, affecting 6%-10% of women, often leads to pain and infertility and its underlying inflammatory mechanisms are poorly understood. We established endometriosis models in wild-type and IL16KO mice, revealing the driver function of IL-16 in initiating endometriosis-related inflammation. Using an in vitro system, we confirmed iron overload-induced GSDME-mediated pyroptosis as a key trigger for IL-16 activation and release. In addition, our research led to the development of Z30702029, a compound inhibiting GSDME-NTD-mediated pyroptosis, which shows promise as a therapeutic intervention for endometriosis. Importantly, our findings extend beyond endometriosis, highlighting GSDME-mediated pyroptosis as a broader pathway for IL-16 release and offering insights into potential treatments for various inflammatory conditions.

Learning to cope with the reality of endometriosis: A mixed-methods analysis of psychological therapy in women with endometriosis

OBJECTIVES

Despite the need and uptake of mental health support by women with endometriosis, no research to date has explored their experience of psychological therapy. We aimed to understand the factors that predict engagement in psychological therapy by Australian women with endometriosis and to qualitative explore their experience of psychological support.

DESIGN

Mixed-methods design.

METHODS

A total of 200 women with self-reported endometriosis were recruited from the community. We explored; (1) the demographic and clinical predictors of engagement in psychological therapy, (2) the psychological approaches that seem most valuable to women in the management of endometriosis and (3) their experience engaging in psychological therapy for endometriosis.

RESULTS

Nearly half of women reported to have seen a psychologist within the past year, particularly for pain. Younger age (OR, .94; 95% CI, .886-.993), depressive symptoms (OR, 1.05; 95% CI, 1.002-1.099), and working part time compared to full time (OR, 2.17, 95% CI, 1.012-4.668), increased the likelihood of engaging in psychological therapy. Template thematic analysis identified three themes; (1) endometriosis and pain have multi-faceted psychological effects, (2) psychological support is sought to adjust and live with endometriosis and (3) there are helpful and unhelpful psychological tools for women with endometriosis.

CONCLUSIONS

Our findings support the use of psychological therapy in the management of endometriosis, and the need for psychological therapy to acknowledge the chronicity and impact of symptoms, to enlist multidisciplinary support and to consider alternative options. Further advocacy is required to educate women on the benefits of psychological therapy for endometriosis.

Pollution and endometriosis: A deep dive into the environmental impacts on women's health

BACKGROUND

The interaction between pollution and endometriosis is a pressing issue that demands immediate attention. The impact of pollution, particularly air and water pollution, or occupational hazards, on hormonal disruption and the initiation of endometriosis remains a major issue.

OBJECTIVES

This narrative review aims to delve into the intricate connection between pollution and endometriosis, shedding light on how environmental factors contribute to the onset and severity of this disease and, thus, the possible public health policy implications.

DISCUSSION

Endocrine-disrupting chemicals (EDCs) in pollutants dysregulate the hormonal balance, contributing to the progression of this major gynaecological disorder. Air pollution, specifically PM2.5 and PAHs, has been associated with an increased risk of endometriosis by enhancing chronic inflammation, oxidative stress, and hormonal imbalances. Chemical contaminants in water and work exposures, including heavy metals, dioxins, and PCBs, disrupt the hormonal regulation and potentially contribute to endometriosis. Mitigating the environmental impact of pollution is required to safeguard women's reproductive health. This requires a comprehensive approach involving stringent environmental regulations, sustainable practices, responsible waste management, research and innovation, public awareness, and collaboration among stakeholders.

CONCLUSION

Public health policies have a major role in addressing the interaction between pollution and endometriosis in a long-term commitment.

Early Quality of Life Assessment After Segmental Colorectal Resection for Deep Infiltrating Endometriosis

STUDY OBJECTIVE

Endometriosis is a benign condition afflicting women of reproductive age that significantly impacts their quality of life (QoL). Given its debilitating symptoms and prevalence, it is essential to define its proper management. In this study, we have assessed patient-reported outcomes among women having undergone segmental colorectal resection for deep infiltrating endometriosis. Any correlation between preoperative nutritional status and overall postoperative complications has also been analyzed.

STUDY DESIGN

Prospective observational study.

SETTING

Public medical center.

PATIENTS

One hundred forty consecutive patients that had undergone segmental colorectal resection for DIE between November 2020 and October 2021 at IRCCS Sacro Cuore Don Calabria Hospital of Negrar of Valpolicella (Verona, Italy).

INTERVENTIONS

Patient-reported outcomes were measured using data collected from the MD Anderson Symptom Inventory for gastrointestinal surgery patients and Euro-QoL Group EQ-5D-5L (EQ-5Q-5L) questionnaires, which were administered preoperatively (T0), at discharge (T1) and at 4 to 6 weeks after surgery (T2). Nutritional status was examined through the Mini Nutritional Assessment Short form and Prognostic Nutritional Index.

MEASUREMENTS AND MAIN RESULTS

A significant improvement in the EQ-5Q-5L and MDASI-GI scores was noted between T0 and T2 (p <. 001 and p <. 001, respectively.) No statistically significant differences were found in scores at T2 between patients who had experienced postoperative complications and those who had not. No statistically significant association was observed between the presence of malnutrition and overall postoperative complications and their severity.

CONCLUSION

This study confirms, through patient-reported outcomes, the pivotal role of surgery in improving the QoL at 4 to 6 weeks of women affected by endometriosis who have previously been unresponsive to medical therapy.

A comprehensive interventional program to improve the sexual function of women with endometriosis: a mixed-methods protocol study

BACKGROUND

Endometriosis is a chronic disease affecting 6-10% of women worldwide. Sexual dysfunction has been reported in a significant percentage of these patients. Thus, the present study will be conducted to design, implement, and determine the effectiveness of an interventional program to improve the sexual function of women with endometriosis.

MATERIALS AND METHODS

This mixed-methods study will be carried out in three phases with a sequential exploratory approach. In the first phase (qualitative study) participants will be selected by purposive sampling in Isfahan, Iran. The data will be collected through in-depth interviews and field notes and analyzed using conventional content analysis. The interventional program will be designed in the second phase based on the results of the qualitative study and literature review and using the Delphi method and panel of experts. The interventional program will be implemented at the individual level in the third phase to investigate its effect on improving women's sexual function. This phase includes quasi-experimental research, in which the pre- and post-intervention data will be collected from the intervention and control groups using the FSFI questionnaire and analyzed by descriptive and inferential statistical methods. Ultimately, a suitable interventional program will be presented by combining the data obtained in the qualitative and quantitative phases of the research.

CONCLUSION

Conducting the present study, along with the design and implementation of an appropriate, native, and culturally sensitive interventional program, can contribute to improving the sexual function of women with endometriosis and enhancing the quality of sexual relations between couples.

Correlation between pain and depressive symptoms in patients with confirmed endometriosis during COVID-19 pandemic

BACKGROUND

Endometriosis is a chronic, estrogen-dependent, inflammatory condition which affects women of reproductive age physically and psychologically in their everyday life. The most common symptom is chronic lower abdominal pain. Apart from physical pain, endometriosis often also leads to an unfulfilled desire to give birth. In general, these two main aspects alone lead to emotional stress for patients and often initiate depressive symptoms. To what extent endometriosis patients are additionally affected by the COVID pandemic and its effects is to be determined in this study.

METHODS

Patients who presented at our endometriosis center and met the study criteria were offered participation in the study. A link to an online questionnaire (SoSci-Survey) was sent by email. The online questionnaire evaluated depressive symptoms before and during the pandemic as well as the pain perception and perceived support during the pandemic. The data of 167 fully completed questionnaires were evaluated and analyzed using SPSS.

RESULTS

The analysis of the questionnaires revealed a significant association between pain levels and depressive symptomatology in endometriosis patients during the pandemic. Patients with more severe pain showed significantly higher depressive symptoms than patients with little or no pain. During the pandemic, patients showed higher depressive symptoms than before. In addition, it was found that those endometriosis patients who felt left alone with their pain due to the consequences of the COVID pandemic, or who felt they had to endure the pain alone, also had higher depressive symptoms.

CONCLUSION

In summary, it can be observed that endometriosis patients with a high pain burden had significantly higher depressive symptoms during the COVID pandemic. The consequences of the pandemic often led to the feeling of having to cope with the symptoms alone or having to endure pain alone, which in turn increased the depressive symptoms. As treating physicians, we should be aware of these connections and try to counteract them with targeted offers and support.

Robotic assisted laparoscopy for deep infiltrating endometriosis

Deep infiltrative endometriosis is a condition affecting up to 15 % of women of childbearing age, defined by extra uterine location of endometrial like tissues. The symptoms of endometriosis range from severe dysmenorrhea to infertility, chronic pelvic pain, bowel dysfunction and urinary tract involvement to name the most common. Endometriosis has an impact on the quality of life of patients, with personal and social consequences. Although medical treatment is indicated in the first instance, surgery may be necessary. Standard laparoscopy has become the gold standard for this surgery. However, surgery for deep infiltrative endometriosis is known to be highly complex, and the significant development of robotic assistance in recent years has had an impact on the evolution of surgical practice. This comprehensive review of the literature provides an overview of the contributions of robotic surgery in the field of endometriosis and gives an insight into the next steps in its development.

Exploration of Diagnostic Deubiquitinating Enzymes in Endometriosis and Its Immune Infiltration

The mechanism involved in the pathogenesis of endometriosis is poorly understood. The purpose of this study is to identify key deubiquitinating enzymes (DUBs) for endometriosis diagnosis and elucidate the possible mechanism, offering novel insights for noninvasive early diagnosis and treatment. Four gene expression datasets were employed from the Gene Expression Omnibus to identify differentially expressed genes (DEGs) between endometriosis and normal controls. GO and KEGG pathways were performed for enrichment analysis. Calibration curves, ROC, DCA, and clinical impact curves verified the clinical usefulness of the nomogram model. In addition, the ssGSEA method was conducted to estimate 23 types of immune cells. A specific DUB gene signature was constructed with Lasso regression, univariate logistic regression, and SVM analysis. RT-qPCR validated the expression of biomarkers. A total of 85 endometriosis-related DUBs were identified in the eutopic endometrium. Among them, 20 DUBs were found to be correlated with the severity of endometriosis. A diagnostic risk model based on five DUB-related genes (USP21, USP48, ZRANB1, COPS5, and EIF3F) was developed using lasso-cox regression analysis. The nomogram model exhibited a strong predictive ability to diagnose endometriosis. KEGG analysis revealed that ubiquitin-mediated proteolysis was activated in patients suffering from severe symptoms. Analysis of immune cell infiltration revealed a positive correlation between USP21 and multiple immune cells in the eutopic endometrium. However, EIF3F showed an opposite relationship. Dysregulation of DUBs was related to the immune microenvironment in endometriosis. Results from RT-qPCR confirmed the expression of DEGs in clinical samples. In summary, the diagnostic model for endometriosis constructed using five differentially expressed DUB genes demonstrates strong diagnostic capability, suggesting that these genes could serve as potential candidate biomarkers and therapeutic targets.

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.

A thematic synthesis of qualitative studies and surveys of the psychological experience of painful endometriosis

BACKGROUND

Endometriosis is a widespread problem in women of reproductive age, causing cyclical and non-cyclical pain in the pelvis and elsewhere, and associated with fatigue, fertility problems, and other symptoms. As a chronic pain problem, psychological variables are important in adjustment and quality of life, but have not been systematically studied.

METHODS

A systematic search of multiple databases was conducted to obtain surveys and qualitative studies of women's experience of pain from endometriosis. Surveys were combined narratively; qualitative studies were combined by thematic synthesis, and the latter rated for methodological quality.

RESULTS

Over 2000 records were screened on title and abstract, and provided 22 surveys and 33 qualitative studies from which accounts could be extracted of the psychological components of pain in endometriosis. Surveys mostly addressed quality of life in endometriosis, with poorer quality of life associated with higher levels of pain and of distress, but few referred to coherent psychological models. Qualitative studies focused rather on women's experience of living with endometriosis, including trajectories of diagnosis and treatment, with a few addressing meaning and identity. Thematic synthesis provided 10 themes, under the groupings of internal experience of endometriosis (impact on body, emotions, and life); interface with the external world (through self-regulation and social regulation); effects on interpersonal and social life, and encounters with medical care.

CONCLUSIONS

The psychological components of pain from endometriosis only partly corresponded with standard psychological models of pain, derived from musculoskeletal pain studies, with fewer fears about physical integrity and more about difficulties of managing pain and other symptoms in social settings, including work. Better understanding of the particular psychological threats of endometriosis, and integration of this understanding into medical care with opportunities for psychologically-based pain management, would substantially improve the experience and quality of life of women with painful endometriosis.

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.

Acupuncture for endometriosis: A systematic review and meta-analysis

Background

Current endometriosis treatments do not always provide symptom relief, with many using complementary approaches. This study examined the effectiveness of acupuncture on pain and quality of life in people with endometriosis.

Methods

Searches were conducted on Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, Allied and Complementary Medicine Database (AMED) and Embase (Ovid), Epistemonikos, and Cumulative Index to Nursing and Allied Health Literature (CINAHL; EBSCOhost) on 20 March 2023. Trials were included if they used penetrating acupuncture. Risk of bias was assessed with Cochrane RoB2 and GRADE for overall evidence certainty. Random-effects meta-analyses were undertaken, using Hedges' g or mean difference (MD) both with 95 % confidence intervals (CI).

Results

Six studies involving a total of 331 participants were included. Evidence for benefit was found for acupuncture compared to non-specific acupuncture on overall pelvic pain (g = 1.54, 95 % CI 0.92 to 2.16, 3 RCTs, n = 231, low certainty evidence, p<0.001), menstrual pain (g = 1.67, 95 % CI 1.23 to 2.12, 1 RCT, n = 106, moderate certainty evidence, p<0.001), and non-specified pelvic pain (MD -2.77, 95 % CI 2.15 to 3.38, 2 RCTs, n = 125, low certainty evidence, p<0.001), and compared to usual care on menstrual pain (g = 0.9, 95 % CI 0.15 to 1.64, 1 RCT, n = 19, very low certainty evidence, p = 0.02). Most studies reported low rates of adverse events.

Conclusion

Acupuncture treatment for endometriosis demonstrated clinically relevant improvements in pelvic pain and should be considered as a potential treatment intervention.

Bibliometric analysis of global endometriosis research, 2002 to 2021: A review

Endometriosis is a common disease of reproductive-age women and an important cause of dysmenorrhea and infertility. Information on endometriosis is complex and there is a lack of summarization of available results. The study aims to evaluate the overall distribution of publications related to endometriosis to provide a foundation for further research. The Web of Science Core Collection was searched for articles published in the field of endometriosis. Our survey revealed the structure, hotspots, and development trends of endometriosis-related research and publications.

Assessment of MMP14, CAV2, CLU and SPARCL1 expression profiles in endometriosis

Endometriotic cells exhibit a notable degree of invasiveness and some characteristics of tissue remodeling underlying lesion formation. In this regard, do matrix metalloproteinases 14 (MMP14) and other related genes such as SPARC-like protein 1 (SPARCL1), caveolin 2 (CAV2), and clusterin (CLU) exert any significant influence in the processes of endometriosis development and pathophysiology is not apparent. We aim to assess whether these genes could serve as potential diagnostic biomarkers in endometriosis. Microarray-based gene expression analysis was performed on total RNA extracted from endometriotic tissue samples treated with and without gonadotropin-releasing hormone agonist (GnRHa). The GnRHa untreated patients were considered the control group. The validation of genes was performed using quantitative real-time polymerase chain reaction (qRT-PCR). qRT-PCR analysis showed significant downregulation in the expression of MMP14 (p = 0.024), CAV2 (p = 0.017), and upregulation of CLU (p = 0.005) in endometriosis patients treated with GnRHa. SPARCL1 did not show any significant (p = 0.30) change in the expression compared to the control group. These data have the potential to contribute to the comprehension of the molecular pathways implicated in the remodeling of the extracellular matrix, which is a vital step for the physiology of the endometrium. Based on the result, it is concluded that changes in the expression of MMP14, CAV2, and CLU post-treatment imply their role in the pathophysiology of endometriosis and may serve as a potential diagnostic biomarker of endometriosis in response to GnRHa treatment in patients with ovarian endometrioma.

Association between depression and endometriosis using data from NHANES 2005-2006

Studies on the association between depression and self-reported endometriosis are limited, and further studies are required to investigate this association. Data were collected from the National Health and Nutrition Examination Survey database (2005-2006). Based on the inclusion and exclusion criteria, 100 participants with self-reported endometriosis and 1295 participants without self-reported endometriosis were included, representing a total population of 64,989,430. Depression severity was assessed using the Patient Health Questionnaire 9 (PHQ9). A survey-weighted logistic regression analysis was performed to explore the association between depression and endometriosis. Subgroup analyses were conducted to explore heterogeneity. The prevalence of endometriosis was 7.17%. A significant positive association was found between the PHQ9 score and endometriosis. After adjusting for all covariates, the PHQ9 score positively correlated with endometriosis. Furthermore, compared with the participants without depression, those with moderate depression were more prone to have endometriosis both in unadjusted and fully adjusted model. However, the relationship between severe depression and endometriosis was not significant in all models (P > 0.05). Our findings highlight the influence of depression on the prevalence of self-reported endometriosis. Further studies are required to elucidate the causal relationship between depression and self-reported endometriosis.

Alexithymia and Loneliness in Women with Endometriosis. Testing the Factorial Structure of the Italian Endometriosis Health Profile (EHP-30) and a Mediation Model

Objective

Endometriosis is a pathological condition characterized by endometrial-like tissue outside the uterus, chronic inflammatory reaction, and pelvic pain that dramatically decrease women's health-related quality of life (HRQoL). Furthermore, this invisible and difficultly diagnosable disease might lead women to experience alexithymia, loneliness, and consequent impairment of perceived quality of life. Firstly, the present study aimed at validating the Italian EHP-30 version which is the most used specific questionnaire for HRQoL measurement. Secondly, the present study aimed at exploring the still understudied relationship between alexithymia and HRQoL in endometriosis conditions, evaluating the mediating role of perceived loneliness.

Method

A total of 435 women with endometriosis (mean age=35.75 years) have been involved. All items were loaded on their own factors.

Results

The measure showed good internal consistency (Cronbach's α ranged between 0.60-0.95 for core and 0.74-0.94 for modular parts). The Italian EHP-30 is a psychometrically valid measure of HRQoL with endometriosis. The tested mediation model provided adequate goodness-of-fit indices (χ2 (51) = 206.071; p < 0.001; RMSEA = 0.084; 90%CI: 0.072, 0.096, CFI = .933, SRMR= 0.058), showing that alexithymia only indirectly affected women's perceived HRQoL, via the mediating effect of feelings of loneliness.

Conclusions

The current study highlighted the pivotal role of perceived loneliness in directly affecting women's quality of life and mediating the effect of the alexithymic experiences.

Time to move beyond surgical classification systems for endometriosis

Endometriosis is a common condition associated with chronic pelvic pain and infertility. Its pathogenesis is poorly understood, diagnosis relies on laparoscopy, and staging is based on extent of disease. Unfortunately, the current staging systems do not correlate well with pain severity and impact, nor do they predict prognosis, i.e., treatment success and recurrence of disease. In this article, we discuss the strengths and limitations of current staging systems and propose modifications that will enable better classification systems to be developed in the future.

Efficacy and safety of oral gonadotropin-releasing hormone antagonists in moderate-to-severe endometriosis-associated pain: a systematic review and network meta-analysis

PURPOSE

The aim of this NMA is to comprehensively analyze evidence of oral GnRH antagonist in the treatment of moderate-to-severe endometriosis-associated pain.

METHODS

Literature searching was performed to select eligible studies published prior to April 2022 in PubMed, Cochrane, Embase and Web of Science. Randomized controlled trials involving patients who suffered from moderate-to-severe endometriosis-associated pain and treated with oral nonpeptide GnRH antagonists or placebo were included.

RESULTS

Elagolix 400 mg and ASP1707 15 mg were most efficient in reducing pelvic pain, dysmenorrhea and dyspareunia. Relugolix 40 mg was best in reducing the analgesics use. The rates of any TEAEs and TEAEs-related discontinuation were highest in relugolix 40 mg and elagolix 250 mg, respectively, while rates of hot flush and headache were highest in relugolix 40 mg and elagolix 150 mg. Significantly decreased spinal BMD was observed in elagolix 250 mg.

CONCLUSION

Oral GnRH antagonists were effective in endometriosis-associated pain in 12w, and most of the efficiency and safety outcomes were expressed in a dose-dependent manner, but linzagolix 75 mg was an exception.

Translocation of vaginal and cervical low-abundance non-Lactobacillus bacteria notably associate with endometriosis: A pilot study

The etiology remains to be understood for endometriosis (EMS) which affected health negatively for 10% of reproductive-age women globally. Emerging studies found the associations of EMS with genital microbiota dysbiosis. However, the role of vaginal and cervical microbiota is not fully understood for Chinese women. This study recruited forty Chinese women (21 healthy women and 19 EMS patients) to analyze vaginal and cervical microbiota using 16S rRNA amplicon sequencing method. For both sites, there were no significant differences for distribution of microbial samples between control and EMS group, which was concordant with dominated Lactobacillus in both groups. In contrast, we observed accumulation of several low-abundance genera in vaginal and cervical microbiota of EMS patients, such as Fannyhessea, Prevotella, Streptococcus, Bifidobacterium, Veillonella, Megasphaera and Sneathia. Random forest analysis found that translocation of these genera had the significant importance in differentiating EMS patients from controls. In addition, cervix/vagina ratio of these genera also associated with EMS severity. And these genera had notable associations with ascending infection-related functional pathways, including flagellar assembly, bacterial motility proteins, bacterial toxins and epithelial cell signaling in Helicobacter pylori infection. These findings suggest that translocation of specific genera between vaginal and cervical sites play a role in EMS.

Co-Existence of Endometriosis with Ovarian Dermoid Cysts: A Retrospective Cohort Study

Both endometriosis and ovarian dermoid cysts are benign conditions characterized by the presence of well-differentiated tissues in ectopic locations. The presence and surgical excision of these entities can potentially impact ovarian reserves, contributing to reduced chances of future pregnancy. The objective of our study is to investigate the bidirectional association between endometriosis and ovarian dermoid cysts, as well as to analyze the clinical characteristics of patients diagnosed with both conditions. A retrospective cohort study was conducted, including women who underwent laparoscopy and received histological diagnoses of endometriosis and/or dermoid cysts between 2011 and 2019 at the Cantonal Hospital of Schaffhausen. We identified 985 women with endometriosis and 83 women with ovarian dermoid cysts. Among these groups, 22 women presented with both endometriosis and ovarian dermoid cysts. The majority of the above patients had endometriosis stage rASRM I-II (72.7%), with peritoneal endometriosis being the most common phenotype of endometriosis (77.2%). Out of the 14 patients with a desire for future pregnancy, the majority (11/14, 78.5%) had an EFI score of 7-8. The prevalence of bilateral ovarian dermoid cysts was higher in women with both ovarian dermoid cysts and endometriosis in comparison to women with ovarian dermoid cysts without endometriosis (18% vs. 6.5%). Our study revealed that 26.5% of women with ovarian dermoid cysts also had endometriosis, a notably higher prevalence than observed in the general population. Clinicians should be aware of this co-existence, and preoperative counseling should be an integral part of the care plan for affected individuals, where the potential risks and the available options for fertility preservation should be discussed in detail.

Biomarkers of endometriosis

Endometriosis is one of the most severe female reproductive disorders, affecting 6-10% of women between 18 and 35. It is a gynaecological condition where endometrial tissue develops and settles outside the uterus. The aetiology of endometriosis is primarily influenced by genetic, epigenetic, and non-genetic variables, making it highly challenging to create a therapeutic therapy explicitly targeting the ectopic tissue. The delay in the treatment is due to the limitations in the diagnostic approaches, which are restricted to invasive techniques such as laparoscopy or laparotomy. This accords to 70% of the women being diagnosed at later stages. By understanding the subject, several treatment medications have been produced to lessen the disease's symptoms. Nevertheless, endometriosis cannot be permanently cured. A viable or persuasive standard screening test for endometriosis must be utilized in a clinical context. A helpful assessment method for the early identification of endometriosis could be biomarkers. A major research priority is the identification of a biomarker that is sensitive and specific enough for detecting endometriosis. The present article has reviewed studies published on the expression of biomarkers of endometriosis. It outlines various biomarkers from different sample types, such as serum/plasma and urine, in addition to tissue. This would provide a non-invasive approach to diagnosing the disease at the initial stages without any harmful repercussions. Future high-throughput advances in science and technology are anticipated to result in the creation of a potent remedy for endometriosis. To achieve successful outcomes, it is necessary to research the discussed biomarkers that demonstrate substantial results extensively.

Physical Activity in Women with Endometriosis: Less or More Compared with a Healthy Control?

BACKGROUND

Endometriosis, i.e., endometrial-like tissue outside the uterus, is a chronic inflammatory condition affecting physical functioning. However, the specific levels of physical activity (PA) in the context of endometriosis and different disease symptoms remain unclear.

METHODS

This multi-center, cross-sectional study compared PA levels and influencing factors in endometriosis patients and non-endometriosis patients. Data were collected through questionnaires. Endometriosis was surgically confirmed. A statistical analysis was performed with appropriate tests.

RESULTS

The study included 460 women with endometriosis and 460 age-matched women without this condition. The two groups did not differ significantly in terms of age, education level, or stable partnership. Women with endometriosis exhibited lower PA levels, practicing fewer hours of sports weekly and climbing fewer stairs daily compared to the control group. These differences remained significant after controlling for confounding factors. Factors such as endometriosis, current dysmenorrhea, and depression were associated with decreased PA.

CONCLUSIONS

These findings suggest that women with endometriosis engage in less PA compared to those without this condition. These results highlight the need for interventions to promote increased PA in endometriosis patients and harness the associated health benefits. Further research is warranted to explore the underlying mechanisms and develop tailored exercise therapies for this population.

Association between anogenital distance as a noninvasive index in the diagnosis and prognosis of reproductive disorder: A systematic review

Background

There are 2 measures of anogenital distance (AGD) in men and women. AGD has been used as an indicator of fetal androgen dysfunction and an adverse outcome in adulthood. Some studies have shown the association of AGD as a predictor in the diagnosis and prognosis of diseases and disorders.

Objective

To systematically summarize the latest evidence for presenting AGD as a new approach for prognosis and early diagnosis of diseases.

Materials and Methods

A systematic review of the available literature was performed using Medline via PubMed, Scopus, and ISI Web of Knowledge up to July 2021, using search terms "anogenital distance" OR "anogenital index" OR "ano genital distance" OR "ano genital index". Language restrictions were not imposed.

Results

After reviewing the retrieved articles, 47 unique studies were included in this systematic review. Different outcomes, including endometriosis, prostate cancer, polycystic ovary syndrome, pelvic organ prolapse, hypospadias, cryptorchidism, fertility and semen parameters, maternal and birth development, and ovarian and gynecological-related disorders, have been studied in the included evidence. A negative association was observed between AGD and endometriosis and hypospadias and a positive association between AGD and prostate cancer, polycystic ovary syndrome, male fetal gender, and fertility parameters.

Conclusion

Using quantitative indicators such as AGD may be a useful clinical tool for the diagnosis of diseases. Although many studies have shown an association between AGD and diseases, some factors, including different measurement methods, different measurement tools, age, and different definitions of AGD, can be involved in the variation of AGD.

Resilience, anxiety, depression, and life satisfaction in women suffering from endometriosis: a mediation model

The main goal of this cross-sectional study was to assess the relationship between resilience and life satisfaction in women suffering from endometriosis and examine anxiety and depression as mediators in this relationship. The study sample included 349 Caucasian women aged from 18 to 56 years (M = 32.94; SD = 6.74) suffering from endometriosis surgically diagnosed and histologically confirmed. The life satisfaction level was assessed by the Satisfaction with Life Scale (SWLS). Unspecific anxiety was evaluated using the General Anxiety Disorder-7 scale (GAD-7). Depression symptoms were assessed using the Patient Health Questionnaire-9 (PHQ-9). Resilience was measured using the Resilience Assessment Scale (SPP-25). Life satisfaction correlated negatively with anxiety and depression, but positively with resilience. Resilience correlated negatively with anxiety and depression. Anxiety and resilience accounted for 25% of the life satisfaction variance. Depression and resilience explained 35% of the variance in life satisfaction. Among resilience components, personal coping skills, tolerance of negative affect, tolerance of failures and treating life as a challenge, openness to new experiences and a sense of humour, and optimistic life attitude and ability to mobilize in difficult situations were the best predictors of life satisfaction. Anxiety and depression may serve as mediators in the relationship between resilience and life satisfaction. Our results suggested that resilience may be related to life satisfaction in women suffering from endometriosis directly and indirectly as mediated by anxiety and depression.

"Illness perceptions and factors of distress as mediators between trait emotional intelligence and quality of life in endometriosis"

Past findings highlighted the presence of distress symptoms and poor quality of life in people with endometriosis. Several studies showed that trait Emotional Intelligence (trait EI) is a key component of one's wellbeing, whilst Illness Perceptions may play an important role in psychological distress and perceived quality of life. The current study sought to test the hypothesis that an association between trait EI and Quality of Life in individuals with endometriosis would be mediated by Illness Perceptions, examining also the relations with General Distress (depression, anxiety, and stress). 364 women with endometriosis aged between 18 and 58 years old (M = 33.87; SD = 8.64) filled a protocol to assess Trait EI, Illness Perceptions, General Distress, and Quality of Life. Structural Equation Modelling was used to assess the relationship between the observed variables. Illness Perception was a mediator in the relationship between Trait EI, General Distress, and Quality of Life. Moreover, General Distress was a mediator between Trait EI and Quality of Life, and between Illness Perceptions and Quality of Life. Results showed that both Trait EI and Illness perceptions are key components for levels of distress and quality of life in women with endometriosis.

The Application of Nanoparticle-Based Imaging and Phototherapy for Female Reproductive Organs Diseases

Various female reproductive disorders affect millions of women worldwide and bring many troubles to women's daily life. Let alone, gynecological cancer (such as ovarian cancer and cervical cancer) is a severe threat to most women's lives. Endometriosis, pelvic inflammatory disease, and other chronic diseases-induced pain have significantly harmed women's physical and mental health. Despite recent advances in the female reproductive field, the existing challenges are still enormous such as personalization of disease, difficulty in diagnosing early cancers, antibiotic resistance in infectious diseases, etc. To confront such challenges, nanoparticle-based imaging tools and phototherapies that offer minimally invasive detection and treatment of reproductive tract-associated pathologies are indispensable and innovative. Of late, several clinical trials have also been conducted using nanoparticles for the early detection of female reproductive tract infections and cancers, targeted drug delivery, and cellular therapeutics. However, these nanoparticle trials are still nascent due to the body's delicate and complex female reproductive system. The present review comprehensively focuses on emerging nanoparticle-based imaging and phototherapies applications, which hold enormous promise for improved early diagnosis and effective treatments of various female reproductive organ diseases.
