Age-Related Differences in Quality of Life in Swedish Women with Endometriosis

Endometriosis in Adolescence: A Narrative Review of the Psychological and Clinical Implications

Endometriosis is a chronic, inflammatory condition where endometrial-like tissue grows outside the uterus, affecting around 10% of women of reproductive age. This condition is associated with debilitating symptoms, including dysmenorrhea, dyspareunia, chronic pelvic pain, fatigue, and infertility. Adolescents with endometriosis face unique challenges, as the disease is often misdiagnosed or undiagnosed for an average of 7-10 years due to its complex and multifactorial nature. Consequently, patients frequently suffer from worsening symptoms and significant psychological distress, including anxiety, depression, and social withdrawal. While there is no definitive cure for endometriosis, treatment approaches typically involve hormonal therapies, lifestyle adjustments (such as diet and exercise), and psychological support. Recent studies emphasize the profound impact of endometriosis on the mental health of adolescents, highlighting the need for a more holistic treatment approach that integrates both medical and psychological care. This narrative review explores the psychological and psychosocial effects of endometriosis in adolescents, examining the biological and psychological mechanisms linking the disease to mental health outcomes. It also discusses current therapeutic strategies, such as cognitive behavioral therapy, mindfulness, and peer support, and underscores the importance of early diagnosis and multidisciplinary care to mitigate both the physical and emotional burdens of the condition. This integrated approach is critical in improving the overall well-being and quality of life for adolescents living with endometriosis.

Navigating menstrual stigma and norms: a qualitative study on young people's menstrual experiences and strategies for improving menstrual health

BACKGROUND

Menstrual health is a recognised important public health issue and is essential for the realisation of gender equality and the achievement of Sustainable Development Goals. This study aimed to explore the menstrual health experiences of young people in Sweden and how the menstrual cycle affects their health and lives. The study also aimed to identify the facilitators and barriers to achieving menstrual health.

METHODS

We conducted a qualitative study in Sweden. Sixteen young people aged 18-28 who have experienced the menstrual cycle participated in individual interviews. Purposeful sampling combined with snowball sampling was applied to recruit the participants. The data were analysed using reflexive thematic analysis.

RESULTS

Participants viewed menstruation as a sign of having a healthy and functioning body. Menstruation was linked to becoming a woman and fostered a sense of community and sisterhood, which was viewed as positive among cis women. Further, the results showed that physical and emotional symptoms related to the menstrual cycle limited the participants' everyday lives and social relationships and had a negative effect on their sexual and mental health. While managing their emotional discomfort and other menstrual complaints, they also had to deal with the public stigma and norms about menstruation contributing to shame and worries. Barriers to menstrual health included stigma and norms related to menstruation, which led to the adoption of expected behaviours, such as avoiding participation in social activities. The normalisation of menstrual complaints also contributed to delays in seeking healthcare, despite having symptoms that had a negative effect on their health. An important factor promoting menstrual health and quality of life is access to prompt treatment to mitigate and decrease symptoms that limit everyday life.

CONCLUSIONS

The results indicate that menstrual stigma and related norms create challenging situations limiting menstruating people's everyday lives and reluctance to seek healthcare despite needing to. To promote the menstrual health of menstruating young people in Sweden, organised and systematic screening of menstrual cycle-related symptoms should be provided within student health services at schools and universities, and primary healthcare. Policymakers should consider integrating stigma-reducing efforts into public health interventions to improve general awareness and promote gender equality.

Menopause and endometriosis

The shift in paradigm from the belief that endometriosis exclusively affects women of reproductive age has brought attention to its manifestation in postmenopausal patients. Despite this emerging awareness, there remains a dearth of information in the literature regarding postmenopausal endometriosis, with uncertainties surrounding its prevalence, clinical significance, optimal management strategies, and prognosis. Clinical manifestations of endometriosis in menopausal patients lack specificity, with pain onset possible at any stage of life. The primary approach for symptomatic postmenopausal endometriosis continues to be surgical excision, serving both diagnostic and therapeutic purposes while mitigating the risk of coexisting malignancies. Managing the disease in postmenopausal women presents challenges due to possible contraindications for menopausal hormone therapy and the elevated risk of recurrence and malignant transformation. However, conclusive data regarding the appropriateness of menopausal hormone therapy in women with endometriosis or a history of the disease are lacking. Current recommendations lean towards prioritizing combined menopausal hormone therapy formulations or tibolone over estrogen-only therapies due to their potentially higher malignancy risk. The possible increased risk of osteoporosis and cardiovascular disease in postmenopausal women with endometriosis is likely linked to a history of surgical menopause at an earlier age, but more research is warranted. This narrative review summarizes the available literature and provides insights into the intricate connection between endometriosis and menopause, shedding light on pathogenesis, symptoms, oncologic risk, diagnosis, and treatment.

Assessment of patient expectations toward health professionals and quality of life among Płock (Poland) residents aged 55 and over: a cohort study

Background

The right attitude of health professionals (mainly doctors) towards patients-particularly older ones-determines patients' level of illness acceptance and quality of life. The aim of the study was to assess patient expectations of health professionals and quality of life among residents of Płock (Poland) aged 55 and over in relation to sociodemographic variables and to examine correlations between these patients' expectations and their quality of life.

Methods

The study included 2040 adults aged 55 and over, with 68.9% being women. A diagnostic survey was used, incorporating sociodemographic questions and two standardized scales: the Patient Request Form (PRF) and the 36-Item Short Form Health Survey (SF-36). This cohort study utilized a multi-stage sampling method, with data collected through a diagnostic survey. Data analysis incorporated ANOVA, post-hoc Fisher's LSD tests, and Pearson's correlation to assess relationships between variables.

Results

Statistically significant differences were observed between male and female respondents in their expectations of health professionals. Women reported higher scores than men across all three PRF scales, including emotional support (4.85 vs. 4.35, p < 0.05), test- and treatment-related information (7.41 vs. 6.81, p < 0.05), and explanation of the illness (6.89 vs. 6.47). A low but statistically significant correlation was found between age and expectations for emotional support (r = 0.162, p < 0.001), as well as test- and treatment-related information (r = 0.122, p < 0.001). Respondents with secondary/post-secondary education reported the highest expectations for explanation of the illness (mean = 7.06) and test- and treatment-related information (mean = 7.64). Meanwhile, respondents with lower education levels, especially those with primary or vocational education, reported the highest expectations for emotional support (mean = 4.93). The average QoL score measured by the SF-36 was 63.45 (SD = 17.68), indicating moderate-to-high overall QoL. The mental component summary score (mean = 65.07, SD = 19.69) was slightly higher than the physical component summary score (mean = 62.70, SD = 18.06). Age was negatively correlated with QoL scores, particularly in the physical component (r = -0.407, p < 0.001). Education level positively influenced QoL, with respondents holding tertiary education reporting the highest QoL scores.

Conclusion

What the older adults included in our study expect most from health professionals is full and ac-curate medical information, particularly information about their health. Overall, the respondents reported moderate, bordering on high, quality of life. The quality of life of the respondents and their expectations of health professionals were influenced by sociodemographic characteristics, and in particular sex, age and education level.

Health and socioeconomic well-being of women with endometriosis and provoked vestibulodynia: Longitudinal insights from Swedish registry data

Endometriosis and provoked vestibulodynia (PVD) are prevalent pain conditions among women of reproductive age, significantly impacting their quality of life and psychological well-being. However, comprehensive evidence regarding the lifelong health and socioeconomic outcomes for these individuals remains scarce. Additionally, many prior studies rely on limited and sometimes unrepresentative samples. This study aims to inform on the long-term consequences of these disorders by examining health, fertility, and employment outcomes in a cohort of women diagnosed with endometriosis and/or PVD, tracing their experiences from childhood to their 40s. Leveraging nationwide administrative data from Sweden and employing a matched case-control design, we investigate both similarities and differences between women with these diagnoses and those without. Our findings indicate that women diagnosed with endometriosis and/or PVD demonstrate elevated healthcare utilization patterns, commencing in their early teenage years and progressively increasing over time. Notably, disparities in labor market outcomes emerge in their 20s, showcasing lower labor earnings and a rise in sickness benefit receipt. Moreover, our results show a higher likelihood among these women to experience mental health disorders and concurrent chronic pain diseases, as well as infertility. While the association between endometriosis and infertility is well-documented, this study offers novel insights into a potential similar link between PVD and infertility. Our study informs healthcare professionals and policymakers about the considerable burden of compromised health, adverse psychosocial well-being, and reduced productivity in the labor market faced by young women with these common pain conditions. These findings underscore the urgency of addressing the multifaceted challenges encountered by individuals diagnosed with endometriosis and PVD across their lifespan.

Observational pilot study on the influence of an app-based self-management program on the quality of life of women with endometriosis

PURPOSE

Endometriosis can significantly impair the quality of life of those affected. Multimodal self-help measures are recommended but often difficult to access. Smartphone apps have been shown to improve the quality of life for other conditions with chronic pain. The aim of this study was to examine whether there is evidence of beneficial effects of the smartphone app "Endo-App®" and whether a multicenter randomized controlled trial should be planned to substantiate these effects.

METHODS

In a sample of N = 106 women affected by endometriosis the present study determined the influence of the use of Endo-App® on their quality of life. Among others, the validated questionnaire Endometriosis Health Profile from Oxford University was used for this purpose.

RESULTS

The use of Endo-App® lead to a highly significant improvement in quality of life already after 2 weeks. A statistically significant change was found for nine out of ten measured variables of quality of life. A series of further analyses validated that the measured positive effects were not due to other confounding factors.

CONCLUSION

In summary, the results indicate that the quality of life of women with endometriosis improved by the digital self-management tool Endo-App®. More studies are needed to further explore the influence of the app on quality of life and as confirmatory evidence of beneficial effects. For this purpose, a randomized controlled trial should be conducted over a longer period of time.

TRIAL REGISTRATION

This trial is registered at clinicaltrials.gov under the registration number NCT05528601 on August 18, 2022. It was retrospectively registered.

Quality of life and symptoms of pain in patients with endometriomas compared to those with other endometriosis lesions: a cross-sectional study

BACKGROUND

Endometriomas are genetically distinct from other endometriosis lesions and could be associated with a predisposition to excessive inflammation. However, differences in clinical presentation between types of endometriosis lesions have not been fully elucidated. This study aimed to investigate the quality of life and pain scores of patients with endometriomas compared to those with other types of endometriosis lesions.

METHODS

A cross-sectional observational study was conducted between January 2020 and August 2023. Patients diagnosed with endometriosis completed the Endometriosis Health Profile 30 pain subscale questionnaire for their quality of life score and rated their endometriosis-associated pain symptoms using an 11-point numerical rating scale. The data were analyzed for comparison through multivariate linear regression models.

RESULTS

A total of 248 patients were included and divided into endometrioma (81, 33%) and nonendometrioma (167, 67%) groups. The mean age of the patients was 37.1 ± 7.5 years. Most participants were Canadian or North American (84%). One-third of the patients reported experiencing up to four concurrent pain symptoms. The most reported pain included deep dyspareunia (90%), chronic pelvic pain (84%) and lower back pain (81%). The mean quality of life score was 45.9 ± 25.9. We observed no difference in quality of life scores between patients with and without endometriomas. Patients with endometriomas had lower mean scores for deep dyspareunia (0.8; 95% CI [0 to 1.5]; p = 0.049) and higher mean scores for superficial dyspareunia (1.4; 95% CI [0.2 to 2.6]; p = 0.028). Comorbid infertility (p = 0.049) was a factor that modified superficial dyspareunia intensity in patients with endometriomas.

CONCLUSION

In patients with endometriosis, evidence was insufficient to conclude that the presence of endometriomas was not associated with a greater or lesser quality of life, but differences in specific symptoms of dyspareunia were identified.

Clinical factors associated with quality of life among women with endometriosis: a cross-sectional study

BACKGROUND

Endometriosis often leads to a decrease in Quality of Life (QoL), due to its impact on various aspects of women's lives, such as social life, mental health, sex life, and working capacity. Although previous studies have assessed QoL in women with endometriosis, few studies have explored the impact of different clinical variables on QoL. The aim of this study was to investigate how women with endometriosis perceive their QoL, and to analyze which clinical factors are associated with QoL.

METHODS

The Endometriosis Health Profile-30 and the ENDOCARE Questionnaire were distributed to 1000 women diagnosed with endometriosis from 10 different clinics across Sweden. The responses from 476 women were included in univariate and multivariable regression analyses, where the clinical factors were correlated with overall QoL and QoL dimensions.

RESULTS

The women participating in this study reported a low QoL. The clinical factors that showed a significant correlation with overall QoL were age at first onset of endometriosis symptoms (β= -0.64, p < 0.001), having more than 10 visits to general practitioners before referral to a gynecologist (β = 5.58, p = 0.036), current or previous mental health issues (β = 7.98, p < 0.001) patient-centeredness (β= -2.59, p < 0.001) and use of opioids (β = 7.14, p = 0.002).

CONCLUSIONS

This study shows that opioid use and mental health issues were associated with a worse QoL, whereas a higher degree of patient-centeredness was associated with a better QoL. The association between opioid use and a worse QoL might not entirely be caused by the opioid use itself but also by symptom severity and mental health issues. An improved patient-centeredness and more focus on taking care of mental health issues would reasonably result in a better QoL for women with endometriosis.

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

OBJECTIVE

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

STUDY DESIGN

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

MAIN OUTCOME MEASURES

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

RESULTS

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

CONCLUSIONS

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

Endometriosis, infertility and occupational life: women's plea for recognition

The objective of this study was to explore and describe the specificities of the occupational life of infertile endometriotic women treated by in vitro fertilization. We conducted a qualitative monocentric study between December 2020 and June 2021. Twelve semi-structured in-depth interviews using a theme-based interview guide with open questions were undertaken with infertile women with deep infiltrating endometriosis. Data analysis was conducted using an inductive approach according to the grounded theory method. Three main themes emerged from the interviews: (i) barriers to reconciling illness and work life, (ii) facilitating factors for well-being at work, and (iii) consequences and outlooks. It appeared that the time of infertility treatment represents a particular period of change in the working lives of women with endometriosis. For most women, these changes are experienced negatively, often with a renunciation of goals. For others, this is the time to communicate the difficulties linked to their illness to their professional entourage. There is a long path ahead to finally achieving recognition of endometriosis in the context of professional life.

Supporting girls with painful menstruation - A qualitative study with school nurses in Sweden

BACKGROUND

Painful menstruation is common among girls. To optimize school nurses' work more knowledge about their experiences of supporting these girls is needed. The aim of this study was to describe school nurses' experiences of supporting girls with menstrual pain.

METHODS

Interviews were conducted with 15 school nurses in Sweden and analyzed using thematic analysis.

RESULTS

Three themes emerged: Taking menstrual pain seriously, Being a disseminator of knowledge, and External conditions for conducting professional work as a school nurse.

CONCLUSION

School nurses felt competent in supporting girls with menstrual pain. However, they lacked structural, written guidelines and routines for how to treat, support, follow-up and refer girls with menstrual pain.

PRACTICE IMPLICATIONS

School education about menstruation and sexual health needs to be strengthened. Cooperation with other healthcare facilities and networks with other school nurses should be increased. Specific guidelines on how to support girls with menstrual pain should be implemented.

Comparing the quality of life of endometriotic patients' before and after treatment with normal and infertile patients based on the EHP30 questionnaire

OBJECTIVE

This study aimed to determine the quality of life (QOL), in patients with endometriosis ± infertility (B and C groups) and compare those to healthy women, and also infertile groups without endometriosis as a control groups (A and D), considering the fact that endometriosis and infertility reduces the quality of life in patients.

METHODS

The present prospective comparative study was carried out between January 2018 and September 2020. A total of 400 women were included (100 women in each group). The participants filled in a validated questionnaire of quality of life, Endometriosis Health Profile-30 (EHP-30), and a visual analog scale of pain used, at the first visit, and 3 months after the medical or surgical treatment in the endometriosis group without infertility, additionally.

RESULTS

The majority of the patients were married, categorized in the middle-class of socio-economic state and housewives. They were of Persian descent. BMI was high in the infertile groups; however, the time of infertility was not different between the two groups of B and C (P = 0.054). The mean score of QOL was significantly lower in B, C, and D groups in comparison to the healthy women as the control group (A) (P < 0.001). Moreover, the infertile group (B), in comparison to endometriosis ± infertility groups (C and D), had the lowest mean score of QOL (P < 0.001). In each group, those who were older and had better educational level reported a better quality of life than other participants in that group. Social support plays a very important role in reducing the endometriosis related pain symptoms both before and after treatment. Three months after the treatment of endometriosis (D), a significant improvement was observed in all the aspects of QOL-related endometriosis. Nonetheless, the improvement of the quality of life in the surgical group was significantly higher than that in the medical treatment. The mean visual analog score of pain decreased from 62.22 ± 22.78, to 5.15 ± 2.73 following the surgical treatment (P < 0.001).

CONCLUSION

The lowest quality of life belonged to the infertile group, followed by the endometriosis group. The quality of life of the endometriosis group improved after the treatment. Thus, endometriotic patients' treatment in terms of improvement of quality of life should be considered by all professional health care teams.

Age-related differences in experienced patient-centred care among women with endometriosis

Younger women with endometriosis report lower quality of life and seek more care. Patient-centeredness is a central part of quality of care. The aim of this study was to investigate if women younger than 35 years experience endometriosis care as less patient-centred than women 35 years and older. The ENDOCARE Questionnaire was sent to 1000 randomly selected women with verified endometriosis from 10 clinics in Sweden. Answers from 469 women were analysed using Mann-Whitney's U-test and Spearman's correlation. Our findings show that younger women experience care as less patient-centred regarding 'Physical comfort,' 'Continuity,' 'Access to care,' 'Technical skills,' and overall patient-centeredness score in comparison with older women. On the contrary, younger women experience more patient-centeredness in 'Emotional support'. Positive correlations were found for age and 'Access to care' and 'Technical skills', while a negative correlation was found for age and 'Emotional support'. Impact StatementWhat is already known on this subject? There is a need for improvement of quality of endometriosis care. Patient-centeredness is an important part of care improvement work. Many factors have an impact on experienced patient-centeredness in endometriosis care, whereof age is one possible determinant. Given the impact of age on QoL and care seeking behaviour, age may also have influence on the experience patient-centeredness.What do the results of this study add? Our findings show that younger women experience their endometriosis care as less patient-centred than older women.What are the implications of these findings for clinical practice and/or further research? Our results highlight the need of improvement of endometriosis care, especially for younger women. The results contribute to the understanding of the experience of patient-centeredness, which may be used as a guidance to how healthcare recourses should be allocated. Further research is needed to identify other factors contributing to the experience of patient-centeredness. Future studies could also evaluate how different interventions can improve patient-centeredness.

Analysis of the Mechanism of GuizhiFuling Wan in Treating Adenomyosis Based on Network Pharmacology Combined with Molecular Docking and Experimental Verification

Background

The effect of GuizhiFuling Wan (GFW) on adenomyosis (AM) is definite. This study aimed to explore the mechanism and key therapeutic targets of GFW in treating AM through network pharmacology combined with molecular docking and experimental verification.

Materials and Methods

In network pharmacology, firstly, the active components of GFW, its drug, and disease targets were screened through several related public databases, and GFW-AM common targets were obtained after the intersection. Then, the biological function (Gene Ontology, GO) and pathway (Kyoto Encyclopedia of Genes and Genomes, KEGG) of GFW in treating AM were enriched and analyzed. Finally, the interaction and binding force between key components and key targets of GFW were verified by molecular docking. In the animal part, the effect of GFW on the expression of matrix metallopeptidase 2 (MMP-2), matrix metallopeptidase 9 (MMP-9), and vascular endothelial growth factor (VEGF) in mice with AM was observed by HE staining, ELISA, and immunohistochemistry.

Results

In this study, 89 active components of GFW, 102 related targets, and 291 targets of AM were collected. After the intersection, 26 common targets were finally obtained. The key active compounds were baicalein, sitosterol, and β-sitosterol, and the key targets were MMP-2, MMP-9, and VEGF. GO and KEGG enrichment analyses showed that biological processes such as the positive regulation of vascular endothelial migration and signaling pathways such as TNF and HIF-1 were involved in regulating angiogenesis, invasion, and metastasis in AM. The molecular docking results showed that baicalein, β-sitosterol, and stigmasterol had better binding potential with MMP-2, MMP-9, and VEGF. The results of in vivo analysis showed that GFW could decrease the serum content and protein expression of MMP-2, MMP-9, and VEGF in mice with AM.

Conclusions

GFW could reduce the expression of MMP-2, MMP-9, and VEGF, which might be an essential mechanism for GFW to inhibit the invasion and metastasis of ectopic tissues of AM.

A prospective study examining the effect of dienogest treatment on endometrioma size and symptoms

OBJECTIVE

We aimed to determine the effect of dienogest on cyst volume, symptoms, and quality of life in patients with endometrioma.

METHOD

This prospective cohort study included 37 patients diagnosed with endometrioma and planned for medical treatment. Subjects were treated with a 3-month oral dose of dienogest 2 mg/day. Pre-treatment and post-treatment endometriosis measurements were assessed via 3D ultrasonography, pain symptoms via 100-mm visual analog scale (VAS), and quality of life via Short Form-36.

RESULTS

The mean age of the patients was 36.0 ± 6.6 years. The mean endometrioma volume was significantly reduced by 31% after treatment (26.7 ± 19.7 mm³) compared to the pre-treatment volume (17.4 ± 11.2 mm³, p < .001). Post-treatment VAS scores of dysmenorrhea, dyspareunia, and chronic pelvic pain VAS values were significantly decreased by 35.5% (p < .001), 37.5% (p < .001), and 38.5% (p < .001), respectively. The mean physical function score and mental health score significantly increased by 15% (p = .009) and 28% (p < .001), respectively.

CONCLUSION

Our findings showed dienogest treatment at oral doses of 2 mg/day for 3 months significantly reducing the size of endometrioma, reducing pain level, and increasing quality of life in women with endometriosis.

Predictors of Psychological Distress in Women with Endometriosis during the COVID-19 Pandemic

Background: Endometriosis is a multifaceted chronic pain condition that can have a negative impact on mental health. Patients suffering from chronic pain may face an additional psychological burden during adversity, such as the COVID-19 pandemic. The main aim of this research was to evaluate the prevalence of self-reported depression and anxiety, the influence of demographic, endometriosis-specific, pandemic-specific factors, and resilience on mental health outcomes of patients with endometriosis. Methods: An online survey was conducted through patient support groups of women suffering from endometriosis during the first wave of the COVID-19 pandemic. The PHQ-4 questionnaire, which combines two items of the Patient Health Questionnaire for Depression (PHQ-2) and two items from the Generalized Anxiety Disorder Scale (GAD-2) was used to assess self-reported mental health. The Brief Resilience Score (BRS) was employed to evaluate resilience. Independent risk and protective factors for mental health were investigated by multivariate logistic regression analyses. Results: The PHQ-4 questionnaire was completed by 274 respondents. More than 40% reached depression (PHQ-2) and anxiety (GAD-2) scores of ≥3, and more than 20% achieved PHQ-2 and GAD-2 scores of ≥5. High resilience was found to be a reliable and strong independent protector for the probability of developing adverse psychological outcomes: OR 0.295, p < 0.001 for developing generalized anxiety disorder (GAD-2 ≥ 3), and OR 0.467, p < 0.001 for having major depression (PHQ-2 ≥ 3). Conclusions: Pain-induced disability is an independent risk factor for developing major depression and anxiety, while resilience was identified as a potential protective parameter in terms of positive psychological outcomes in women with endometriosis. The results of this study may help to identify women at risk for adverse mental health outcomes and should encourage healthcare practitioners to establish strategies for the reduction of negative psychological and psychiatric impacts on patients with endometriosis.

Sexual function and quality of life in women with endometriosis

Endometriosis may exert a profound negative influence on the lives of individuals with the disorder, adversely affecting quality of life, participation in daily and social activities, physical and sexual functioning, relationships, educational and work productivity, mental health, and well-being. Symptoms of endometriosis represent a great source of stress and cause a substantial negative impact on the psychological parameters, on the daily life and on the physical functioning of patients. The impact of endometriosis on work attendance has very significant economic consequences, as lost productivity has an associated cost, as do career changes resulting from a decline in education due to symptoms. Endometriosis is a pathology that affects all aspects of women's lives and that thus, it must be treated with a multidisciplinary vision that includes not only a medical approach but also psychological, work, and economic support. In this specific long-term vision of patient-centered endometriosis care, aspects of quality of life and sexual health play a key role and should always be evaluated with any patient as part of a multidisciplinary management.

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

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

Correlates of Sexual Function in a Sample of Spanish Women with Endometriosis

BACKGROUND

In the present study, we aim to report on the sexual function of women experiencing symptoms of endometriosis, analysing the clinical and psychosocial factors that may be associated.

METHODS

A multicentre cross-sectional study was performed to analyse the sexual function in a sample of 196 Spanish women with endometriosis, using the Female Sexual Function Inventory.

RESULTS

The Female Sexual Function Inventory (FSFI) was validated in our endometriosis study group. The mean FSFI score for the sample was 22.5 (SD 6.6), with 20.9 and 26.9 being in the 25th and 75th percentiles, respectively. Although physical sexual pain and dyspareunia were factors that influenced the sexual function of women with endometriosis, our results show that the impairment was multifactorial.

CONCLUSIONS

We found impaired sexual function in women diagnosed with endometriosis. The final model included deep endometriosis, depression, age, and unemployment as strongest predictive factors for poor (deteriorated) sexual function.

Evaluation of the SF-36 questionnaire for assessment of the quality of life of endometriosis patients undergoing treatment: A systematic review and meta-analysis

Endometriosis has a negative influence on the physical, psychological, and social aspects of a patient's life; therefore, it affects the health-related quality of life (HRQoL). The current review aimed to investigate the efficiency of a 36-item generic questionnaire survey (SF-36) for patients with endometriosis who were undergoing medical or surgical treatment. A search strategy including the key words ‘endometriosis’, ‘quality of life’ (QOL), and ‘questionnaire SF-36’ was applied using the PubMed/MEDLINE, EMBASE, and Cochrane databases in order to include articles that evaluated the QOL among women with endometriosis using the SF-36. Only articles that included interviews of patients both before and after surgical or medical endometriosis treatment or those articles that compared study groups were considered. The qualitative analysis was based on 37 articles, whereas the quantitative analysis utilized 14 articles. The research participants included 11,101 women, among whom 6,888 patients were diagnosed with endometriosis. The analysis recorded 17 studies dealing with all types of endometriosis, 9 studies dealing with deep infiltrative endometriosis (DIE), and 9 studies dealing with bowel endometriosis or DIE with bowel involvement. QOL was evaluated using only SF-36 in 12 studies that collectively included 1,912 women and using SF-36 in association with other questionnaires in 25 studies that collectively included 8,022 women. For patients with endometriosis, physical functioning [odds ratio (OR), 78.87; 95% confidence interval (CI), 68.97-88.77; I²=98.77%; P≤0.001] was the most affected life parameter. This parameter showed the highest improvement after surgical intervention (OR, 63.39; 95% CI, 48.71-78.07; I²=97.65%; P≤0.001) or hormonal treatment (OR, 38.65; 95% CI, 14.39-62.91; I²=38.65%; P≤0.001). The 36-item survey generic questionnaire seems to be an efficient tool for assessment of the QOL of life of women with endometriosis who are undergoing surgical or medical treatment. It can be applied before and after the procedure, and it can also be used for comparing study groups.

Health-Related Quality of Life in Adult Spanish Women with Endometriomas or Deep Infiltrating Endometriosis: A Case-Control Study

Endometriosis is a disabling disease that may significantly compromise a woman’s social relationships, sexuality, and mental health. Considering the impact of endometriomas and deep infiltrating endometriosis (DIE) on quality of life and the limited number of papers on this topic, the objective of this study was to assess health-related quality of life (HRQoL) in adult Spanish women with the condition. A case-control study was conducted on a group of 99 patients with ovarian endometriomas or DIE and 157 controls. Women underwent physical and gynecological examinations, and they completed health questionnaires including the Short Form-12v2 (SF-12v2), a survey for HRQoL. Eight scales and two component summary scores (Physical (PCS) and Mental (MCS), respectively) were calculated. Women with endometriomas or DIE had significantly worse PCS: 47.7 ± 9.7 vs. 56.1 ± 5.9, respectively (p < 0.001) compared to controls, as well as lower scores on seven out of the eight scales (p < 0.01). No significant differences were found for the MCS. Conclusions: HRQoL was significantly lower in patients with endometriomas or DIE compared to controls. If confirmed, these results may have important implications for prevention, clinical practice, and intervention.

Endometriosis-associated pain: a review of quality of life, sexual health and couple relationship

INTRODUCTION

Endometriosis is a chronic gynecological disease that affects women's quality of life, sexuality, and relationship. Endometriosis-associated pain plays an essential role in well-being impairment. The present review aimed to analyze literature about endometriosis-associated pain and quality of life, sexual health, and quality of the relationship, assessing the role of the biopsychosocial factors involved and the women's pain experience.

EVIDENCE ACQUISITION

Bibliographic research of relevant articles published from 2015 to 2020 in PubMed, Google Scholar, Web of Science, Scopus, EBSCO, and Cochrane Library.

EVIDENCE SYNTHESIS

Endometriosis is associated with impairing all women's quality of life domains, and pain appears to be the most influential variable. The pain mechanism is not simple and implies several biological, psychological, and social factors. Women's sexual health is also impaired, and patients report dyspareunia, sexual dysfunctions, dissatisfaction, and distress. Partners' sexual well being is compromised as well. Endometriosis negatively influences relationship quality, and the illness burden affects both couple members.

CONCLUSIONS

A multidisciplinary team using a couple-centered and a biopsychosocial approach is crucial to provide appropriate treatment for endometriosis-associated pain. A better comprehension of all bio-psycho-social aspects implicated in women's well-being and pain experience needs more research.

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

Endometriosis may exert a profound negative influence on the lives of individuals with the disorder, adversely affecting quality of life, participation in daily and social activities, physical and sexual functioning, relationships, educational and work productivity, mental health, and well-being. Over the course of a lifetime, these daily challenges may translate into limitations in achieving life goals such as pursuing or completing educational opportunities; making career choices or advancing in a chosen career; forming stable, fulfilling relationships; or starting a family, all of which ultimately alter one's life trajectory. The potential for endometriosis to impact the life course is considerable, as symptom onset generally occurs at a time of life (menarche through menopause, adolescence through middle age) when multiple life-changing and trajectory-defining decisions are made. Using a life-course approach, we examine how the known effects of endometriosis on life-domain satisfaction may impact health and well-being across the life course of affected individuals. We provide a quasi-systematic, narrative review of the literature as well as expert opinion on recommendations for clinical management and future research directions.

Better quality of life and less caregiver strain in young-onset Parkinson's disease: a multicentre retrospective cohort study

BACKGROUND

Parkinson's disease (PD) is typically considered as a disease of the elderly. However, there is a sizeable subgroup of patients where PD starts at a younger age, known as young-onset PD (YOPD). We evaluated the differences in quality of life and caregiver strain between YOPD and later onset PD (LOPD) patients in a large cohort.

METHODS

In collaboration with the Parkinson Foundation Quality Improvement Initiative (PF-QII), we conducted a retrospective three-year analysis on 962 PD patients of the QII database (starting date May 2016). Of these, 272 patients had YOPD, and 690 had LOPD. The Parkinson's Disease Questionnaire-39 (PDQ-39) total score served as primary outcome measure. Furthermore, we analysed group differences in modified caregiver strain index (MCSI) total score, three cognition functions, and number of falls. A regression analysis adjusting for covariates was used to assess the association of age at onset with PDQ-39 and MCSI.

RESULTS

PDQ scores were better in YOPD patients, MCSI scores on social constraint were lower in YOPD patients, but scores on financial constraint were higher in this group. After adjusting for covariates, YOPD patients had better quality of life and less caregiver strain at all follow-up moments, but not at baseline. Decline over time for all outcomes was lower in the YOPD group compared to the LOPD group. Cognitive functioning and number of falls progressed slower in the YOPD group compared to the LOPD group.

CONCLUSION

Compared to LOPD patients, YOPD patients had a better quality of life, less caregiver strain, fewer falls and better cognitive functioning after their first follow-up visit, and also a slower decline over time.

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

Endometriosis is a chronic, inflammatory disease affecting more than 170 million women worldwide and up to 10% of women of reproductive age. As a consequence of inflammatory reaction and infiltration of anatomic structures, endometriosis can cause “pain symptoms” including dysmenorrhea, dyspareunia, dyschezia, dysuria, and chronic pelvic pain. In this review, we summarized the impact of endometriosis on quality of life in all its aspects including sexual life, work, and social relationships. The data research was conducted using web-based search engines and/or various electronic research databases querying for all articles related to endometriosis and quality of life from the inception of the database up to February 2020. Endometriosis has not only physical but also psychological effects, causing depression, anxiety, and compromising social relationships. Furthermore, endometriosis negatively impacts sexual life and social relationships. At last, the economic burden of endometriosis should not be underestimated, both individually and for the community, as this pathology leads to a loss of productivity at work and large use of health resources. Thus, endometriosis-related symptoms control women’s lives compromising the quality of life in all aspects. In this review, we summarized the impact of endometriosis on various aspects of women’s lives.

Clinical aspects and the quality of life among women with endometriosis and infertility: a cross-sectional study

Background

The quality of life (QoL) of patients with endometriosis and infertility was assessed in different stages and correlated with the clinical features of the cases.

Methods

The present study was a cross-sectional study; 106 women were included, divided in two endometriosis groups (Grade I/II, 26 women, and Grade II/IV, 74 women). All participants attended the Endometriosis and Infertility Outpatient Clinic of the Instituto Ideia Fértil de Saúde Reprodutiva, Faculdade de Medicina do ABC, São Paulo, Brazil, were and responded to the Short Form (SF) Health Survey-36. Convenience sampling was used due to the authors’ access to the study population; however, the sample number was calculated to be sufficient for 95% power in both groups.

Results

Homogeneity was observed between Grade I/II and Grade III/IV staging, with similar mean ages (35.27, ±3.64 years and 34.04, ±3.39 years, respectively, p = 0.133); types of infertility (p = 0.535); infertility time (p = 0.654); degrees of pain (p = 0.849); and symptoms common to endometriosis, namely, dysmenorrhea (p = 0.841), dyspareunia (0.466), chronic pelvic pain (p = 0.295), and intestinal (p = 0.573) or urinary (p = 0.809) diseases. Comparisons of median scores in the QoL domains demonstrated that the distributions of QoL and clinical symptoms were significantly related between the types of dyspareunia and the following domains: physical functioning (p = 0.017), role- emotional (p = 0.013), and general health (p = 0.001). Regarding pain outside of menstruation, there was significance in the pain domain (p = 0.017), and degree of pain was significance in physical functioning (p = 0.005) and role-physical (p = 0.011) domains.

Conclusions

The present study pointed out that it is not the stage of endometriosis that interferes in the quality of life of women with endometriosis and infertility but rather the clinical manifestations, such as dyspareunia and pain. Thus, we can conclude that the patient’s perception of the disease should be considered in health care and that the losses are independent of the degree of endometriosis in this population with the aggravating factor of infertility.

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

AIM

To explore endometriosis-related fatigue (ERF), health-related fitness, sleep quality, and health-related quality of life (HRQoL) in women with endometriosis in comparison with matched controls.

METHODS

Twenty-five affected women and twenty-five age and height-matched women without endometriosis were included. ERF was assessed through the Piper Fatigue Scale; health-related fitness was assessed through the Schöber, flamingo, and 6-min walking tests and dynamometry; and body composition was assessed through impedanciometry. Self-perceived physical fitness, sleep quality, and HRQoL were assessed through the International Fitness Scale, the Pittsburgh Sleep Quality Index, and the 12-item Short Form Health Survey, respectively.

RESULTS

Affected women exhibited higher levels of ERF than controls, increased fat mass, and physical deconditioning (reduced back strength, lumbar flexibility, body balance, and functional capacity, p-values < 0.050). Moreover, cases also had poorer perceived physical fitness, sleep quality, and HRQoL (p-value < 0.050). Finally, we observed deteriorated health-related fitness, sleep quality, and HRQoL in those women with endometriosis with higher levels of ERF.

CONCLUSIONS

This study constitutes the first evidence that women with endometriosis describe a generalized physical deconditioning, even more pronounced in affected women with higher levels of ERF. Further studies assessing the efficacy of rehabilitation interventions to face these physical impairments in women with endometriosis are warranted.

Cross-Sectional Associations of Fatigue Subtypes with Pain Interference in Younger, Middle-Aged, and Older Adults with Chronic Orofacial Pain

Objective

Mental, emotional, physical, and general fatigue, as well as vigor, have each been associated with pain interference—defined as pain-related disruption of social, recreational, and work-related activities—in patients with chronic orofacial pain (COFP). The objectives of the current study were to compare levels of these fatigue subtypes across younger, middle-aged, and older patients with COFP and test the associations between fatigue subtypes and pain interference in these age groups.

Design

A cross-sectional cohort design was used.

Setting

Participants self-reported fatigue subtypes (Multidimensional Fatigue Symptom Inventory–Short Form), pain interference (West Haven–Yale Multidimensional Pain Inventory), pain intensity (visual analog scale), pain duration (months), depression (Symptom Checklist 90–Revised), and sleep quality (Pittsburgh Sleep Quality Index) at their initial appointment at a tertiary orofacial pain clinic.

Subjects

Sixty younger (age 18–39), 134 middle-aged (age 40–59), and 51 older (age 60–79) COFP patients provided data for the study.

Methods

Analysis of variance was used to compare levels of fatigue subtypes between the age groups. Regression with dummy-coding was used to test if the relationship between fatigue subtypes and pain interference varied by age.

Results

Older COFP patients reported less general fatigue and more vigor than younger or middle-aged adults. Fatigue subtypes were each associated with greater pain interference, but associations became nonsignificant after controlling for depression, sleep, and pain intensity/duration. Age group–by–fatigue subtype interactions were not observed.

Conclusions

Managing fatigue may be important to reduce pain interference in COFP populations and may be accomplished in part by improving depression and sleep.

Surgical treatment of endometriosis: prognostic factors for better quality of life

The present study investigated the effect of surgical treatment of endometriosis on physical and mental health. We undertook a prospective survey including 153 premenopausal women with histological diagnosis of endometriosis. The Short Form 12 (SF-12) questionnaire comprising physical and mental component scales was used. Two groups of patients were distinguished: Group A (n = 42) with SF-12 scores above the median in both physical and mental scales; Group B (n = 111) with SF-12 scores below the median in either physical or mental scale. Group A was diagnosed and operated for endometriosis for the first time at an older age (30 vs. 26 years), had undergone more frequently a single surgical intervention (64% vs. 46%), was less affected by symptom or lesion recurrence and had reported less intense current pain symptoms than Group B. Having the first endometriosis surgery at a later age was an independent predictor of better health status (adjusted odds ratio 1.146 per year, 95% confidence interval 1.058-1.242) after accounting for the potential confounding effects of reoperation, pelvic pain and time elapsed since the first surgery. In conclusion, patients with endometriosis who had a single surgery at an older age have good symptom control and better quality of life (QoL).

Systematic review of quality of life measures in patients with endometriosis

OBJECTIVES

Endometriosis and quality of life has been the subject of much research, however, there is little consensus on how best to evaluate quality of life in endometriosis, resulting in many and diverse scales being used. In our study, we aim to identify quality of life scales used in endometriosis, to review their strengths and weaknesses and to establish what would define an ideal scale in the evaluation of endometriosis-related quality of life.

MATERIALS AND METHODS

A search of the MEDLINE and EMBASE databases was carried out for publications in English and French for the period from 1980 to February 2017, using the words 'endometriosis' and 'quality of life'. Publications were selected if they reported on quality of life in patients with endometriosis and specified use of a quality of life scale. A quantitative and a qualitative analysis of each scale was performed in order to establish the strengths and weaknesses for each scale (systematic registration number: PROSPERO 2014: CRD42014014210).

RESULTS

A total of 1538 articles publications were initially identified. After exclusion of duplicates and application of inclusion criteria, 201 studies were selected for analysis. The SF-36, a generic HRQoL measure, was found to be the most frequently used scale, followed by the EHP-30, a measure specific to endometriosis. Both perform well, when compared with other scales, with scale weaknesses offset by strengths. EHP-5 and EQ-5D also showed to be of good quality. All four were the only scales to report on MCID studied in endometriosis patients.

CONCLUSION

For clinical practice, routine evaluation of HRQOL in women with endometriosis is essential both for health-care providers and patients. Both SF-36 and EHP-30 perform better overall with regard to their strengths and weaknesses when compared to other scales.

The Impact of Endometriosis on Quality of Life in Adolescents

PURPOSE

While endometriosis is recognized to have a high patient burden for adults, the level of morbidity it causes for adolescents has been understudied, and may be minimized by clinicians. The purpose of this study was to determine whether endometriosis has a significant impact on quality of life (QOL) for adolescents and young adults.

METHODS

Five hundred and sixty-seven participants (360 cases and 207 controls) aged <25 years old who are enrolled in the Women's Health Study: From Adolescence to Adulthood longitudinal study were included in this analysis. Participants were enrolled from medical clinics and the communities surrounding Boston, MA. Participants completed an expanded World Endometriosis Research Foundation Endometriosis Phenome and Biobanking Harmonization Project standard clinical questionnaire that included the Short Form-36 (SF-36), a widely used measure of health-related QOL. We calculated SF-36 physical component summary and mental component summary scores, as well as eight subscale scores. On the SF-36, lower scores reflect greater impairment.

RESULTS

Adolescents with endometriosis had significantly lower physical component summary (mean [standard deviation]: 43.4 [11.1] vs. 53.8 [7.6], p < .0001) and mental component summary (43.3 [12.3] vs. 46.3 [10.8], p = .008) scores compared to controls, as well as lower scores on all eight subscales. More cases than controls reported mental health diagnoses, pain medication use, and avoidance of exercise during menstruation. Among cases, earlier age at menarche, more severe pelvic pain, and longer duration of diagnostic delay were associated with poorer QOL.

CONCLUSIONS

Endometriosis is associated with significantly worse reports of QOL for adolescents and young women with endometriosis compared to unaffected peers. Earlier menarche was associated with poorer physical health-related QOL among cases, whereas severe pelvic pain was associated with both poorer physical and mental health-related QOL among cases. Impairment in QOL is not limited to adults with endometriosis, but affects younger patients as well.

Examining subjective wellbeing and health-related quality of life in women with endometriosis

The purpose of this study was to explore the subjective wellbeing, health-related quality of life and lived experience of women living with endometriosis. In 2015 five hundred participants between the ages of 18-63 (M = 30.5, SD = 7.46) were recruited through Endometriosis Australia and social media, completing an online questionnaire comprising the Personal Wellbeing Index, the Endometriosis Health Profile-30 and various open-ended questions. Results found that women with endometriosis reported low levels of subjective wellbeing (mean PWI total scores of 51.5 ± 2.03), considerably below the normative range of 70-80 for western populations. The mean Endometriosis Health Profile total score indicated a very low health-related quality of life amongst the women in this sample (78.9, ±13.14). There was also a significant relationship between scores on the Endometriosis Health Profile and Personal Wellbeing Index. The findings from the qualitative data suggest that endometriosis impacts negatively on women's lives in several areas such as; social life, relationships and future plans, this in turn affects women's overall life quality. The study highlights the strong negative impact that endometriosis can have on women's subjective wellbeing and health related quality of life, contributing to productivity issues, relationship difficulties and social dissatisfaction and increasing the risk of psychological comorbidities.

Social psychogenic stress promotes the development of endometriosis in mouse

Exposure to chronic stress before and well after the induction of endometriosis is reported to increase lesion sizes in rats, but it is unclear whether stress, exposed shortly after the induction of endometriosis, would also promote the development of endometriosis, nor is it clear what the underlying possible molecular mechanism is. This study was undertaken to test the hypothesis that chronic stress can promote the development of endometriosis. A prospective randomized mouse experiment was conducted that subjected mice with induced endometriosis to predator stress. In addition, a cross-sectional immunohistochemistry study was performed in ectopic and eutopic endometrial tissue samples from age- and roughly menstrual phase-matched women with ovarian endometriomas. It was found that the chronic psychogenic stress induced epigenetic changes in the hippocampus in mouse independent of endometriosis. It was also found that chronic psychogenic stress induced epigenetic changes in the hippocampus of mice with endometriosis, and seemingly activated the adrenergic signalling in ectopic endometrium, resulting in increased angiogenesis and accelerated growth of endometriotic lesions. Thus, chronic psychogenic stress promotes endometriosis development, raising the possibility that the use of anti-depressants in cases of prolonged and intense stress might forestall the negative impact of stress on the development of endometriosis.

Endometriosis-Derived Thromboxane A2 Induces Neurite Outgrowth

Hyperinnervation in endometriosis is now well documented, but so far only a few neurotrophins have been identified. Since endometriotic stromal cells secrete thromboxane A2 (TXA₂), we sought to determine whether TXA₂, derived from endometriotic stromal cells, induces neurite outgrowth. Using primary sensory neurons derived from rat dorsal root ganglia (DRG) and ectopic endometrial stromal cells (EESCs) derived from human ovarian endometrioma tissues, we treated the primary neurons with different concentrations of U-46619, a stable TXA₂ mimetic, and performed a neuronal growth assay. The primary neurons were also cocultured with a vehicle, nerve growth factor (NGF, serving as a positive control), the supernatant of EESC culture medium, or the supernatant of EESCs pretreated with ozagrel, a thromboxane synthase inhibitor, and a neuronal growth assay was performed. The total neurite length was evaluated through immunofluorescence microscopy. We found that U-46619 significantly increased the neurite outgrowth in DRG neurons in a concentration-dependent fashion ( P < .001). It also increased the number of neurite ends in a concentration-dependent fashion. Ozagrel treatment alone had no effect on the neurite growth ( P > .05), and the treatment with the supernatant of EESCs induced neurite outgrowth just as potently as that treated with NGF (positive control; P > .05). Remarkably, treatment with the EESC supernatant increased the neurite outgrowth by nearly 3-fold as compared with the control ( P < .01), but the pretreatment with ozagrel abolished the stimulatory effect of the EESC by 31.3% ( P < .05). These findings indicate that EESCs potently induce neurite outgrowth, and endometriosis-derived TXA₂ is responsible, at least in part, for this neurotrophic effect.

Chronic stress accelerates the development of endometriosis in mouse through adrenergic receptor β2

STUDY QUESTION

Does chronic stress in mice accelerate the development of endometriosis, and, if so, through what mechanism?

SUMMARY ANSWER

Exposure to chronic stress accelerates the development of endometriosis and exacerbates the endometriosis-associated generalized hyperalgesia, most likely through activation of the adrenoceptor β2 (ADRB2) and cAMP responsive element-binding protein (CREB).

WHAT IS KNOWN ALREADY

Women with endometriosis tend to have higher levels of psychological stress, which is known to impact negatively on health in general and to promote tumor growth and metastasis in particular. Exposure to chronic stress before and after the induction of endometriosis is reported to increase lesion sizes in rodents, but it is unclear whether adrenoceptors are involved or not in the stress-promoted development of endometriosis.

STUDY DESIGN, SIZE, DURATION

Three independent, prospective, randomized mouse experimentations. A total of 184 virgin female Balb/C mice were used.

PARTICIPANTS/MATERIALS, SETTING, METHODS

In Experiment 1, the mice were randomly divided into four groups: the control group, which received no stress; the before, after and both groups, which received immobilization stress before, after and both before and after the induction of endometriosis, respectively. In Experiment 2, mice were randomly divided into four groups one day after the induction of endometriosis: phosphate buffer saline (PBS) and propranolol (PROP) groups, which received the mini-pump containing, respectively, PBS only and propranolol (a non-selective ADRB antagonist) but no stress, STR+PROP and STR+PBS groups, which received stress and the mini-pump containing, respectively, propranolol and PBS. The immobilization stress started after the insertion of mini-pumps. In Experiment 3, mice were induced with endometriosis. Three days after the induction, they were randomly divided into four groups: control, ADRAa, ADRB2a, and ADRBa, which received the mini-pump containing solution only, metaraminol (a non-specific α adrenoceptor agonist), tebutaline (a specific ADRB2 agonist), or isoproterenol (a non-specific ADRB agonist), respectively. In all three experiments, the bodyweight and hotplate latency were evaluated before sacrifice 14 days after the induction. In all experimentations, the lesion weight was evaluated and the harvested ectopic endometrial tissue samples were subjected to immunohistochemistry analysis of vascular endothelial growth factor (VEGF), CD31-positive microvessels, proliferating cell nuclear antigen (PCNA), phosphorylated CREB, ADRB1, ADRB2, ADRB3, adrenergic receptor α1 (ADRA1) and ADRA2.

MAIN RESULTS AND THE ROLE OF CHANCE

Exposure to chronic stress accelerated the development of endometriosis and exacerbated the endometriosis-associated generalized hyperalgesia. This promotional effect is likely to be mediated through the systemic activation of the sympatho-adreno-medullary (SAM) axis, which results in subsequent release of catecholamines. The surging catecholamines may activate ADRB2 and CREB, yielding increased angiogenesis and cellular proliferation in ectopic endometrium in mice with induced endometriosis. In addition, β adrenergic receptor blockade completely abolished the promotional effect of chronic stress, likely through suppression of ADRB2 and CREB activation, thus suppressing angiogenesis and proliferation. Moreover, a non-specific adrenergic β agonist and a specific adrenergic β2 agonist, but not non-specific adrenergic α agonist, acted similarly to chronic stress, accelerating the development of endometriosis and exacerbating the generalized hyperalgesia in mice with pre-existing endometriosis.

LARGE SCALE DATA

NA.

LIMITATIONS, REASONS FOR CAUTION

This study is limited by the use of immunohistochemistry analyses only and the lack of molecular data.

WIDER IMPLICATIONS OF THE FINDINGS

The present study provides the experimental evidence that chronic stress can promote the development of endometriosis through the activation of ADRB2. Given ADRB2 is also expressed in human endometriosis and appears to be functional, and in light of recent awareness that adrenergic signaling plays critical roles in tumorigenesis, it is likely that adrenergic signaling may play important roles in the development of endometriosis and is potentially a target for intervention.

Practices and Attitudes Concerning Endometriosis Among Nurses Specializing in Gynecology

Endometriosis is a chronic disease affecting approximately 10% of fertile women. These women often have negative health care experiences. This study adds new knowledge about endometriosis care in a hospital setting and nurses' attitudes toward the disease. To explore how the personal attitudes of gynecological nurses, their specialized knowledge, and their clinical experiences influenced the way they conceptualized and cared for women with endometriosis, participant observations and semistructured interviews were conducted. Categorization of patients into certain kinds, with more or less legitimate needs, provided an important framework for practice. Specialized knowledge qualified the nurses' views of their patients and seemed to be conducive to sustained patient involvement. However, the organization of care based solely on medical specialization restricted a holistic approach. An important goal is, therefore, to investigate patients' perspectives of health and illness and to create participatory relationships with patients, regardless of their diagnosis.
