Abstract
INTRODUCTION Endometriosis pathogenesis is still a matter of debate. It is now agreed that a complex cooperation of genetic, hormonal, immune and environmental factors is implicated. However, no consensus has been reached yet on what firstly is responsible for the initiation, promotion and survival of endometrial-like tissue outside the uterine cavity. Since consistent evidence have found immunological alterations in women with the disease, the impairment of immune system has been considered for decades one of the possible causes of endometriosis. The aim of this literature review is to summarize the available findings on a particular aspect of this topic represented by the inhibition of natural killer (NK) cell activity in women affected as a paradigmatic example of the complexity in studying the pathogenesis of endometriosis. EVIDENCE ACQUISITION Advanced search of PubMed for English articles published between 1990 and September 2020 using the keywords "endometriosis" or "endometrioma" or "endometriotic" or "ectopic endometrium" in combination with "natural killer cells" (NK). EVIDENCE SYNTHESIS Consistent studies have found an impairment in NK cell activity in women with endometriosis especially in advanced stages of disease (stage III/IV). Reports to explain these findings support the phenomenon as a consequence of the disease establishment. Evidence from genetic studies have questioned the role of these dysfunctions in the pathogenesis of the disease. CONCLUSIONS Immunological dysfunctions and the decreased NK cell cytotoxicity may only represent consequence of endometriosis, although the underlining mechanisms still need to be elucidated.

Cosmetic and personal care product use, urinary levels of parabens and benzophenones, and risk of endometriosis: results from the EndEA study. ENVIRONMENTAL RESEARCH 2021; 196:110342. [PMID: 33069703 DOI: 10.1016/j.envres.2020.110342] [Citation(s) in RCA: 26] [Impact Index Per Article: 8.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/02/2020] [Revised: 09/28/2020] [Accepted: 10/07/2020] [Indexed: 06/11/2023]
Abstract
AIM To explore the relationship of urinary concentrations of different congeners of benzophenones and parabens with the utilization of cosmetics and personal care products (PCPs) and their impact on the risk of endometriosis, and to evaluate the influence of oxidative stress on associations found. METHODS This case-control study comprised a subsample of 124 women (35 cases; 89 controls). Endometriosis was confirmed (cases) or ruled out (controls) by laparoscopy, with visual inspection of the pelvis and biopsy of suspected lesions (histological diagnosis). Urinary concentrations of benzophenone-1 (BP-1), benzophenone-3 (BP-3), 4-hydroxibenzophenone (4-OH-BP), methyl- (MeP), ethyl- (EtP), propyl- (PrP), and butyl-paraben (BuP), and biomarkers of oxidative stress [lipid peroxidation (TBARS) and total antioxidant power (TAP)] were quantified. Information was gathered on the frequency of use of cosmetics and PCPs. Associations between the frequency of cosmetics/PCP use, urinary concentrations of benzophenones and parabens, oxidative stress, and endometriosis risk were explored in logistic and linear multivariable regression analyses. RESULTS The frequency of utilization of certain cosmetics and PCPs was significantly associated with urinary concentrations of benzophenones and parabens. After adjustment for potential confounders, the risk of endometriosis was increased in women in the second versus first terciles of MeP (OR = 5.63; p-value<0.001), BP-1 (OR = 5.12; p-value = 0.011), BP-3 (OR = 4.98; p-value = 0.008), and ƩBPs (OR = 3.34; p-value = 0.032). A close-to-significant relationship was observed between TBARS concentrations and increased endometriosis risk (OR = 1.60, p-value = 0.070) and an inverse association between TAP concentrations and this risk (OR = 0.15; p-value = 0.048). Oxidative stress results did not modify associations observed between benzophenone/paraben exposure and endometriosis risk. CONCLUSIONS Our findings indicate that the frequency of cosmetics and PCP utilization is a strong predictor of exposure to certain benzophenone and paraben congeners. These compounds may increase the risk of endometriosis in an oxidative stress-independent manner. Further studies are warranted to corroborate these findings.

Abstract
Adenomyosis is characterised by epithelial gland and mesenchymal stroma invasion of the uterine myometrium. Adenomyosis is an oestrogen-dependent gynaecological disease in which a number of factors, such as inflammatory molecules, prostaglandins (PGs), angiogenic factors, cell proliferation and extracellular matrix remodelling proteins, also play a role as key disease mediators. In this study, we used mice lacking both lipocalin and hematopoietic-PG D synthase (L- and H-Pgds) genes in which PGD2 is not produced to elucidate PGD2 roles in the uterus. Gene expression studied by real-time PCR and hormone dosages performed by ELISA or liquid chromatography tandem mass spectroscopy in mouse uterus samples showed that components of the PGD2 signalling pathway, both PGDS and PGD2-receptors, are expressed in the mouse endometrium throughout the oestrus cycle with some differences among uterine compartments. We showed that PGE2 production and the steroidogenic pathway are dysregulated in the absence of PGD2. Histological analysis of L/H-Pgds-/- uteri, and immunohistochemistry and immunofluorescence analyses of proliferation (Ki67), endothelial cell (CD31), epithelial cell (pan-cytokeratin), myofibroblast (α-SMA) and mesenchymal cell (vimentin) markers, identify that 6-month-old L/H-Pgds-/- animals developed adenomyotic lesions, and that disease severity increased with age. In conclusion, this study suggests that the PGD2 pathway has major roles in the uterus by protecting the endometrium against adenomyosis development. Additional experiments, using for instance transcriptomic approaches, are necessary to fully determine the molecular mechanisms that lead to adenomyosis in L/H-Pgds-/- mice and to confirm whether this strain is an appropriate model for studying the human disease.

Adenomyosis is associated with specific proton nuclear magnetic resonance ( 1H-NMR) serum metabolic profiles. Fertil Steril 2021; 116:243-254. [PMID: 33849709 DOI: 10.1016/j.fertnstert.2021.02.031] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2020] [Revised: 02/15/2021] [Accepted: 02/16/2021] [Indexed: 12/17/2022]
Abstract
OBJECTIVE To determine whether the adenomyosis phenotype affects the proton nuclear magnetic resonance (1H-NMR)-based serum metabolic profile of patients. DESIGN Cohort study. SETTING University hospital-based research center. PATIENTS Seventy-seven patients who underwent laparoscopy for a benign gynecologic condition. INTERVENTIONS Pelvic magnetic resonance imaging and collection of a venous peripheral blood sample were performed during the preoperative workup. The women were allocated to the adenomyosis group (n = 32), or the control group (n = 45). The adenomyosis group was further subdivided into two groups: diffuse adenomyosis of the inner myometrium (n = 14) and focal adenomyosis of the outer myometrium (n = 18). Other adenomyosis phenotypes were excluded. MAIN OUTCOME MEASURES Metabolomic profiling based on 1H-NMR spectroscopy in combination with statistical approaches. RESULTS The serum metabolic profiles of the patients with adenomyosis indicated lower concentrations of 3-hydroxybutyrate, glutamate, and serine compared with controls. Conversely, the concentrations of proline, choline, citrate, 2-hydroxybutyrate, and creatinine were higher in the adenomyosis group. The focal adenomyosis of the outer myometrium and the diffuse adenomyosis phenotypes also each exhibited a specific metabolic profile. CONCLUSION Serum metabolic changes were detected in women with features of adenomyosis compared with their disease-free counterparts, and a number of specific metabolic pathways appear to be engaged according to the adenomyosis phenotype. The metabolites with altered levels are particularly involved in immune activation as well as cell proliferation and cell migration. Nevertheless, this study did find evidence of a correlation between metabolite levels and symptoms thought to be related to adenomyosis. Further studies are required to determine the clinical significance of these differences in metabolic profiles.

Abstract
Adenomyosis is associated with dysmenorrhea, infertility, and lesional fibrosis. The pathogenesis of adenomyosis is still unclear. Plasminogen activator inhibitor 1 (PAI-1) plays important roles in pathological activities like tumor metastasis and endometriosis. Our objective was to investigate the expression and localization of PAI-1 in eutopic and ectopic endometrium with adenomyosis and in endometrium without adenomyosis. We also sought to determine the relationship between PAI-1 immunoreactivity and the severity of dysmenorrhea and the extent of lesional fibrosis in adenomyosis. PAI-1 expression was significantly higher in the ectopic endometrium of patients with adenomyosis than in both the eutopic endometrium of patients with adenomyosis and the endometrium of controls. Ectopic PAI-1 expression correlated positively with dysmenorrhea visual analog scale (VAS) scores and the extent of lesional fibrosis in adenomyosis. High PAI-1 expression increased the likelihood of moderate to severe dysmenorrhea in adenomyosis. These results suggest that PAI-1 is involved in the adenomyosis-associated dysmenorrhea and lesional fibrosis, which provide a potential target in treating symptomatic adenomyosis.

Abstract
Objective The aim of the study was to investigate pregnancy, obstetric, and neonatal outcomes in women with small (<4 cm) unilateral endometriomas. Methods This retrospective study included 177 patients: 91 patients with small endometriomas and 86 controls with unexplained or tubal factor infertility who were treated at the Süleymaniye Gynecology and Maternity Training and Research Hospital Infertility Unit between January 2010 and July 2015. The groups were matched with regards to demographic characteristics such as age, body mass index, and infertility duration. All of the women in this study conceived via intracytoplasmic sperm injection. We compared pregnancy, obstetric, and neonatal outcomes between these groups. Results Women with endometriomas had a higher biochemical pregnancy rate, but lower clinical pregnancy and live birth rates than women with unexplained and tubal factor infertility (p<0.05 for all). However no significant differences were found in terms of obstetric and neonatal complications between the two groups (p>0.05 for all). Conclusion In this study, we found that women with endometriomas less than 4 cm were more prone to early pregnancy complications. We also showed that this group did not have any increased risks of late pregnancy, obstetric, and neonatal complications.

Elevated Circular RNA PVT1 Promotes Eutopic Endometrial Cell Proliferation and Invasion of Adenomyosis via miR-145/Talin1 Axis. BIOMED RESEARCH INTERNATIONAL 2021; 2021:8868700. [PMID: 33728345 PMCID: PMC7936912 DOI: 10.1155/2021/8868700] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/14/2020] [Revised: 02/04/2021] [Accepted: 02/11/2021] [Indexed: 01/13/2023]
Abstract
Several theories on the origin of adenomyosis (ADS) have been proposed, of which the most widely accepted is the fundamental pathogenic role of uterine eutopic endometrium. Emerging evidence suggests that circular RNAs participate in the multiple tumorgenesis. The vital importance of circular RNA PVT1 (circPVT1) in the pathological progress like malignancies has been well documented. Nevertheless, its underlying correlation with ADS remains elusive yet. The purpose of this study was to investigate the expression pattern, regulatory effect, and internal mechanism of circPVT1 in ADS. qRT-PCR was performed to detect the relative mRNA expression of circPVT1, miR-145, and Talin1 in ADS endometrial tissue and cells. The protein level of Talin1 was measured by Western blot and immunochemistry. Immunofluorescence was used to identify the primary endometrial epithelial and stromal cells. circPVT1 knockdown in vitro was achieved by transfecting with specific lentivirus vector CCK-8, and colony formation assays were utilized to assess cell proliferation; meanwhile, the transwell assay was employed for evaluating cell invasion ability. By conducting bioinformatics, dual-luciferase reporter assay, or RNA immunoprecipitation (RIP) experiment, the interaction between miR-145 and circPVT1 or Talin1 was verified. Rescue experiments further determined the regulatory effect of circPVT1/miR-145/Talin1 axis. We found both circPVT1 and Talin1 were markedly upregulated in ADS endometrial tissue and cells, whereas miR-145 was decreased. Elevated expression of circPVT1 was closely related to the severity of dysmenorrhea, menorrhagia, and uterine enlargement of patients with ADS. Knockdown of circPVT1 inhibited adenomyotic epithelial and stromal cell proliferation and invasion. Further mechanistic experiments revealed that circPVT1 negatively regulated miR-145 through serving as a molecular sponge. And the facilitating effect of circPVT1 was partially reversed by miR-145. Talin1 was demonstrated to be a down target of miR-145 and indirectly affected by circPVT1. Our findings unveiled that enhanced circPVT1 may be involved in the pathogenesis of ADS via stimulating endometrial cell proliferation and invasion. The establishment of circPVT1/miR-145/Talin1 pathway might present a novel therapeutic insight for ADS.

Abstract
Adenomyosis (ADS) is a commonly encountered benign gynecological disorder. Epithelial-mesenchymal transition (EMT) may serve a pivotal role in the pathogenesis of ADS. Talin1 has been identified to be implicated in multiple human carcinomas, probably through inducing EMT process. However, available data on the precise molecular mechanism of Talin1 in the pathogenesis of ADS remain extremely scanty. In the present study, we aim to investigate the clinical roles of Talin1 and its effects on uterine endometrial cell migration, invasion, and EMT in ADS. Relative mRNA expression of Talin1, microRNA-145-5p (miR-145-5p), and EMT-related markers was determined by qRT-PCR. Immunohistochemistry and immunofluorescence were performed to examine the distribution of Talin1 in ADS endometrium. Protein levels of Talin1, EMT-related markers, and wnt/β-catenin pathway were measured by western blot. Wound healing assay and transwell assay were utilized for evaluating cell migration and invasion respectively. Dual-luciferase reporter assay was performed to verify the relationship between Talin1 and miR-145-5p. We found Talin1 was markedly overexpressed in ADS endometrial tissue and cells, whereas miR-145-5p was downregulated. Elevated Talin1 mRNA level might be closely related to some clinicopathological features of ADS. Through functional experiments, we demonstrated that overexpression of Talin1 induced EMT and enhanced migration and invasion ability of ADS eutopic and ectopic endometrial epithelial cells (ADS_Eu_EEC and ADS_Ec_EEC) in vitro through activating the canonical wnt/β-catenin pathway. From a mechanistic perspective, Talin1 was inversely regulated by miR-145-5p as a direct target. Our findings unveiled that under the regulation of miR-145-5p, Talin1 might promote endometrial cell migration and invasion through inducing EMT, presenting a novel insight for elucidating the pathogenesis of ADS.

Abstract
The aim of this review is to clarify the relative association between adenomyosis and infertility and the possible treatment for an infertile patient. Although adenomyosis is detected more often in women of late reproductive age, its influence on pregnancy rates is important, especially considering the tendency to delay pregnancy among women in developed countries. In this article, we present a critical analysis of the literature data concerning the impact of adenomyosis on fertility. The possible effects of treatment on the pregnancy rate will also be discussed. We conducted a literature search; publications from Pubmed, Embase and Cochrane databases published from 1982 to 2019 were retrieved using terms 'adenomyosis and infertility' and 'adenomyosis and pregnancy outcomes', extensively studied in the aspects of diagnosis, pathogenesis of infertility and possible treatment methods. Molecular studies have given deep insight into the pathogenesis of adenomyosis in the recent few years, but there is a huge discrepancy between in vitro studies and praxis. Oral contraceptive pills, anti-prostaglandins, oral or parenteral progestins, danazol and gonadotrophin-releasing hormone (GnRH) analogues have all been used to control menstrual pain and menorrhagia in women with adenomyosis, but they temporarily suppress the menstrual cycle. Additionally, endometrial ablation and hysterectomy used to alleviate pain caused by adenomyosis exclude pregnancy planning. The development of imaging techniques-ultrasound and MRI-enables the diagnosis of adenomyosis with very high accuracy nowadays, but the methods of treatment mentioned above have not given satisfactory results in women planning pregnancy. For these patients, the high-intensity-focused ultrasound method (HIFU) and combined treatment before assisted reproductive techniques can prove beneficial in adenomyosis patients.

Abstract
To summarize and update our current knowledge regarding adenomyosis diagnosis, prevalence, and symptoms. Systematic review of PubMed between January 1972 and April 2020. Search strategy included: "adenomyosis [MeSH Terms] AND (endometriosis[MeSH Term OR prevalence study [MeSH Terms] OR dysmenorrhea[Text Word] OR prevalence[Text Word] OR young adults [Text Word] OR adolesce* [Text Word] OR symptoms[Text Word] OR imaging diagnosis [Text Word] OR pathology[Text Word]. Articles published in English that addressed adenomyosis and discussed prevalence, diagnosis, and symptoms were included. Included articles described: pathology diagnosis, imaging, biopsy diagnosis, prevalence and age of onset, symptoms, and concomitant endometriosis. Sixteen articles were included in the qualitative analysis. The studies are heterogeneous when diagnosing adenomyosis with differing criteria, protocols, and patient populations. Prevalence estimates range from 20% to 88.8% in symptomatic women (average 30-35%) with most diagnosed between 32-38 years old. The correlation between imaging and pathology continues to evolve. As imaging advances, newer studies report younger symptomatic women are being diagnosed with adenomyosis based on both magnetic resonance imaging (MRI) and/or transvaginal ultrasound (TVUS). High rates of concomitant endometriosis create challenges when discerning the etiology of pelvic pain. Symptoms that are historically attributed to endometriosis may actually be caused by adenomyosis. Adenomyosis remains a challenge to identify, assess and research because of the lack of standardized diagnostic criteria, especially in women who wish to retain their uterus. As noninvasive diagnostics such as imaging and myometrial biopsies continue to improve, younger women with variable symptoms will likely create criteria for diagnosis with adenomyosis. The priority should be to create standardized histopathological and imaging diagnoses to gain deeper understandings of adenomyosis.

Miscarriage on Endometriosis and Adenomyosis in Women by Assisted Reproductive Technology or with Spontaneous Conception: A Systematic Review and Meta-Analysis. BIOMED RESEARCH INTERNATIONAL 2020; 2020:4381346. [PMID: 33490243 PMCID: PMC7787757 DOI: 10.1155/2020/4381346] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/13/2020] [Accepted: 11/22/2020] [Indexed: 11/22/2022]
Abstract
Background In the past several years, there has been an increasing concern on miscarriage caused by endometriosis or adenomyosis. However, the results reported by different studies remain controversial. The present study is aimed at assessing the impact of endometriosis and adenomyosis on miscarriage. Materials and Methods Searches were carried out in PubMed, Embase, and the Cochrane library for studies published from inception until February 29, 2020. The investigators included studies that evaluated miscarriage risk in pregnant women with endometriosis or adenomyosis by assisted reproductive technology (ART), or with spontaneous conception (SC). Miscarriage (<28 weeks) was the primary outcome. The secondary outcomes were antepartum hemorrhage (APH), postpartum hemorrhage (PPH), preterm birth, low birthweight, placenta praevia, placental abruption, ectopic pregnancy, stillbirth, gestational diabetes, preeclampsia, and intrauterine growth restriction (IUGR). Endnote was used for the study collection, and the data analyses were carried out by two authors using Review Manager version 5.2. Results Thirty-nine studies, which is comprised of 697,984 women, were included in the present study. Miscarriage risk increased in women with endometriosis in SC (OR: 1.81, 95% CI: 1.44-2.28, I2 = 96%) compared with those without endometriosis, while women with endometriosis who underwent ART had a similar miscarriage risk, when compared to those with tubal infertility (OR: 1.03, 95% CI: 0.92-1.14, I2 = 0%). Compared with those without adenomyosis, women with adenomyosis had an augmented miscarriage risk in ART (OR: 2.81, 95% CI: 1.44-5.47, I2 = 64%). Compared with those without endometriosis, women with endometriosis had higher odds of APH, PPH, preterm birth, stillbirth, and placenta praevia. No difference was observed in the incidence of ectopic pregnancy, placental abruption, pre-eclampsia, gestational diabetes, low birthweight, and IUGR. Conclusion Women with endometriosis had an augmented miscarriage risk in SC and a similar miscarriage risk during ART. Adenomyosis was associated with miscarriage in pregnant women using ART.

Abstract
Adenomyosis remains an enigmatic disease in the clinical and research communities. The high prevalence, diversity of morphological and symptomatic presentations, array of potential etiological explanations, and variable response to existing interventions suggest that different subgroups of patients with distinguishable mechanistic drivers of disease may exist. These factors, combined with the weak links to genetic predisposition, make the entire spectrum of the human condition challenging to model in animals. Here, after an overview of current approaches, a vision for applying physiomimetic modeling to adenomyosis is presented. Physiomimetics combines a system's biology analysis of patient populations to generate hypotheses about mechanistic bases for stratification with in vitro patient avatars to test these hypotheses. A substantial foundation for three-dimensional (3D) tissue engineering of adenomyosis lesions exists in several disparate areas: epithelial organoid technology; synthetic biomaterials matrices for epithelial–stromal coculture; smooth muscle 3D tissue engineering; and microvascular tissue engineering. These approaches can potentially be combined with microfluidic platform technologies to model the lesion microenvironment and can potentially be coupled to other microorgan systems to examine systemic effects. In vitro patient-derived models are constructed to answer specific questions leading to target identification and validation in a manner that informs preclinical research and ultimately clinical trial design.

Abstract
Women's health concerns are generally underrepresented in basic and translational research, but reproductive health in particular has been hampered by a lack of understanding of basic uterine and menstrual physiology. Menstrual health is an integral part of overall health because between menarche and menopause, most women menstruate. Yet for tens of millions of women around the world, menstruation regularly and often catastrophically disrupts their physical, mental, and social well-being. Enhancing our understanding of the underlying phenomena involved in menstruation, abnormal uterine bleeding, and other menstruation-related disorders will move us closer to the goal of personalized care. Furthermore, a deeper mechanistic understanding of menstruation-a fast, scarless healing process in healthy individuals-will likely yield insights into a myriad of other diseases involving regulation of vascular function locally and systemically. We also recognize that many women now delay pregnancy and that there is an increasing desire for fertility and uterine preservation. In September 2018, the Gynecologic Health and Disease Branch of the Eunice Kennedy Shriver National Institute of Child Health and Human Development convened a 2-day meeting, "Menstruation: Science and Society" with an aim to "identify gaps and opportunities in menstruation science and to raise awareness of the need for more research in this field." Experts in fields ranging from the evolutionary role of menstruation to basic endometrial biology (including omic analysis of the endometrium, stem cells and tissue engineering of the endometrium, endometrial microbiome, and abnormal uterine bleeding and fibroids) and translational medicine (imaging and sampling modalities, patient-focused analysis of menstrual disorders including abnormal uterine bleeding, smart technologies or applications and mobile health platforms) to societal challenges in health literacy and dissemination frameworks across different economic and cultural landscapes shared current state-of-the-art and future vision, incorporating the patient voice at the launch of the meeting. Here, we provide an enhanced meeting report with extensive up-to-date (as of submission) context, capturing the spectrum from how the basic processes of menstruation commence in response to progesterone withdrawal, through the role of tissue-resident and circulating stem and progenitor cells in monthly regeneration-and current gaps in knowledge on how dysregulation leads to abnormal uterine bleeding and other menstruation-related disorders such as adenomyosis, endometriosis, and fibroids-to the clinical challenges in diagnostics, treatment, and patient and societal education. We conclude with an overview of how the global agenda concerning menstruation, and specifically menstrual health and hygiene, are gaining momentum, ranging from increasing investment in addressing menstruation-related barriers facing girls in schools in low- to middle-income countries to the more recent "menstrual equity" and "period poverty" movements spreading across high-income countries.

Abstract
PURPOSE OF REVIEW To investigate the JZE alterations in gynecological and obstetrical disorders and impact on diagnosis, prognosis and treatment. RECENT FINDINGS JZE was found to be significantly extended in patients with endometriosis, leading to the conclusion that endometriosis is a primary disease of the uterus, much like adenomyosis. Statistical correlation was then demonstrated between the severity of endometriosis and the depth of the adenomyosis infiltrates, hence the thickening of the JZE. Stem cells, predominantly found in the JZE were also found in histological sections of leiomyoma, suggested to be the origin of leiomyoma. This reservoir of JZE stem cells is influenced by different stressors leading to their differentiation into leiomyoma, endometriosis, adenomyosis or endometrial cancer, according to the stressor. The variability in presentation was hypothesized to be connected to genetic and epigenetic factors. JZE was also suggested to act as a barrier, stopping endometrial carcinoma cells invasion and metastasis. In addition, JZE plays a major role in conception, pregnancy and postpartum. SUMMARY JZE is an important anatomical landmark of the uterus contributing to normal uterine function under the influence of ovarian hormones. Alterations of the JZE thickness and contractility can be used as pathognomonic clinical markers in infertility and chronic pelvic pain, for subendometrial and myometrial disorders, for example, adenomyosis and fibroids. Prospective randomized control trials will clarify the diagnostic steps, imaging modalities to follow and probably triage the patients between medical and surgical treatments.

Abstract
Oxidative stress (OS) has been proposed to play a role in the development of EMs. Peroxiredoxins are a family of antioxidant proteins that exhibit peroxidase activity in a thioredoxin-dependent manner, protecting cells against OS. The Western blotting results showed that the relative expression of PRDX4 was significantly increased in ectopic endometria compared with the normal endometria of EMs-free (p < .05). The H2O2 concentration was also significantly higher in the ectopic endometrium. PRDX4 siRNA was transfected into primary ectopic endometrial stromal cells (EESCs). The viability of the transfected EESCs was measured by CCK-8 assay, and the results showed significantly decreased cell viability. Furthermore, the apoptosis rate and ROS generation in flow cytometry assays were significantly increased after the knockdown of PRDX4 expression (p < .05). Scratch assays and transwell assays revealed that decreased expression of PRDX4 mediated by siRNA inhibited EESC migration and invasion. In conclusion, these findings indicate the potential role of PRDX4 in the development of EMs and PRDX4 as a possible therapeutic target for EMs treatment.

Abstract
Aquaporin 2 (AQP2), AQP5 and AQP8 participate in adenomyosis (AM). Ηowever, the roles of these three molecules in AM have not been fully elucidated. In the present study, Institute of Cancer Research female mice were used to establish a model of AM. Subsequently, the endometrial tissues of the mice were observed by hematoxylin-eosin staining, and AM severity, uterus diameter, uterus index, ovary index and numbers of nodules on the uterine surface were evaluated and counted. In addition, eutopic and ectopic endometrial stromal cells (ESCs) were isolated from eutopic and ectopic endometrial samples derived from patients with AM and were then identified by immunofluorescence. The viability, and migratory and invasive ability of ESCs transfected with small interfering RNA targeting AQP5 (siAQP5) were determined by Cell Counting Κit-8, scratch wound-healing and Transwell assays, respectively. Reverse transcription-quantitative polymerase chain reaction was performed to determine the mRNA expression levels of AQP5, epithelial-mesenchymal transition (EMT)-related genes (E-and N-cadherin), matrix metalloproteinase (MMP)-2 and −9. Protein expression levels of AQP2, AQP5, AQP8, E-, N-cadherin, MMP-2 and −9 were detected by western blotting. AM severity and uterus index were higher, and there were a greater number of nodules on the uterine surface in the AM group compared with the sham group. AQP2, AQP5 and AQP8 proteins were highly expressed in eutopic and ectopic endometrium of the AM group, and AQP5 was more highly expressed than AQP2 or AQP8. In addition, the data showed that Vimentin was positively expressed in ESCs, and that siAQP5 suppressed the mRNA expression levels of AQP5, cell viability, migration, invasion, EMT and MMP-2 and −9 expression in ESCs. In conclusion, AQP2, AQP5 and AQP8 were highly expressed in eutopic and ectopic endometrium. Notably, AQP5 silencing may suppress AM by inhibiting viability, migration, invasion, EMT, and MMP-2 and −9 expression in ESCs.

Abstract
Endometriosis represents a frequently diagnosed gynecological affliction in the reproductive timespan of women, defined by symptoms ranging from pelvic pain to infertility. A complex interplay between the genetic profile, hormonal activity, menstrual cyclicity, inflammation status, and immunological factors define the phenotypic presentation of endometriosis. To date, imaging techniques represent the gold standard in diagnosing endometriosis, of which transvaginal ultrasonography and magnetic resonance imaging bring the most value to the diagnostic step. Current medical treatment options for endometriosis-associated infertility focus on either stimulating the follicular development and ovulation or on inhibiting the growth and development of endometriotic lesions. Techniques of assisted reproduction consisting of superovulation with in vitro fertilization or intrauterine insemination represent effective treatment alternatives that improve fertility in patients suffering from endometriosis. Emerging therapies such as the usage of antioxidant molecules and stem cells still need future research to prove the therapeutic efficacy in this pathology.

Abstract
Adenomyosis and endometriosis are common gynecological disorders, but their pathophysiology is still under debate. The aim of this review is to discuss whether adenomyosis and endometriosis represent two different entities or different phenotypes of a single disease. We searched PubMed electronic databases published between January 2000 and April 2020. Endometriosis is classified into three phenotypes; superficial peritoneal disease (SUP), ovarian endometrioma (OMA) and deep infiltrating endometriosis (DIE) lesions. Adenomyosis presents several different subtypes, including intrinsic adenomyosis, extrinsic adenomyosis, adenomyosis externa and focal adenomyosis located in the outer myometrium (FAOM). Human uterus is embryologically composed of archimetra, originating from the Müllerian duct, and neometra, arising from the non-Müllerian duct, and adenomyosis and endometriosis are diseases of archimetra. The outer myometrial layer of the uterus is composed of highly differentiated smooth muscle cells (SMCs), while the inner myometrial cells are immature. Inappropriate uterine contractions can cause retrograde menstruation and chronic inflammation in the pelvic cavity, then influencing the development of pelvic endometriosis. Furthermore, hyperperistalsis results in physiological and pathological changes to the endometrial-myometrial junctional barrier, allowing invagination of the normal endometrial tissue into the inner myometrial layer. This can trigger the development of intrinsic adenomyosis. There are insufficient data available to draw conclusions, but extrinsic adenomyosis may result from pelvic endometriosis and FAOM from rectal and bladder DIE/adenomyosis externa. In conclusions, this paper contributes to the debate in the possibility that adenomyosis and endometriosis represent different phenotypes of a single disease.

[PMID: 32570986 PMCID: PMC7357060 DOI: 10.3390/jcm9061915] [Citation(s) in RCA: 47] [Impact Index Per Article: 11.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2020] [Revised: 06/10/2020] [Accepted: 06/10/2020] [Indexed: 12/22/2022] Open
Abstract
Epithelial-mesenchymal transition (EMT) is an important process of cell remodeling characterized by the gradual loss of the epithelial phenotype and progressive gain of a mesenchymal phenotype. EMT is not an all-or-nothing process, but instead a transition of epithelial to mesenchymal cells with intermediate cell states. Recently, EMT was described in endometriosis, and many EMT-specific pathways like Twist, Snail, Slug, Zinc finger E-box-binding homeobox 1/2 (ZEB1/2), E/N-cadherin, keratins, and claudins are involved. However, as pointed out in this review, a comparison of the eutopic endometrium of women with and without endometriosis yielded only subtle changes of these EMT markers. Furthermore, only very few alterations in cell-cell contacts could be found but without changes in the epithelial phenotype. This suggests only a partial EMT which is not a prerequisite for the detachment of endometrial cells and, thus, not critical for the first step(s) in the pathogenesis of endometriosis. In contrast, the majority of changes in the EMT-related marker expression were found in the ectopic endometrium, especially in the three endometriotic entities, ovarian, peritoneal, and deep infiltrating endometriosis (DIE), compared with the eutopic endometrium. In this review, we examine the most important EMT pathways described in endometriosis and propose that partial EMT might result from the interaction of endometrial implants with their surrounding microenvironment.

Pathophysiologic mechanisms by which adenomyosis predisposes to postpartum haemorrhage and other obstetric complications. Med Hypotheses 2020; 143:109833.

Abstract
Adenomyosis is characterized by the presence of ectopic endometrium within the myometrium. This features lead to structural changes in the surrounding myometrium and endometrium resulting also in functional changes. Alterations in the myometrium are suspected to lead to defective remodeling of spiral arteries during the early stages of decidualization resulting in altered vascular resistance and defective placentation. These alterations could play a common part in the association between adenomyosis and major obstetric complications. Latest epidemiological studies show that adenomyosis is associated with preterm birth, preeclampsia, IUGR and increased caesarean section rates, but very little is known of any underlying mechanism linking postpartum hemorrhage and adenomyosis. It is our opinion that adenomyosis may increase the risk of postpartum hemorrhage through several mechanisms that will be further clarified. Women with adenomyosis may require specific management during pregnancy and may benefit from wider understanding of the pathological mechanisms associated with this disease process.

Abstract
Adenomyosis is a common disorder of the uterus, and is associated with an enlarged uterus, heavy menstrual bleeding (HMB), pelvic pain, and infertility. It is characterized by endometrial epithelial cells and stromal fibroblasts abnormally found in the myometrium where they elicit hyperplasia and hypertrophy of surrounding smooth muscle cells. While both the mechanistic processes and the pathogenesis of adenomyosis are uncertain, several theories have been put forward addressing how this disease develops. These include intrinsic or induced (1) microtrauma of the endometrial-myometrial interface; (2) enhanced invasion of endometrium into myometrium; (3) metaplasia of stem cells in myometrium; (4) infiltration of endometrial cells in retrograde menstrual effluent into the uterine wall from the serosal side; (5) induction of adenomyotic lesions by aberrant local steroid and pituitary hormones; and (6) abnormal uterine development in response to genetic and epigenetic modifications. Dysmenorrhea, HMB, and infertility are likely results of inflammation, neurogenesis, angiogenesis, and contractile abnormalities in the endometrial and myometrial components. Elucidating mechanisms underlying the pathogenesis of adenomyosis raise possibilities to develop targeted therapies to ameliorate symptoms beyond the current agents that are largely ineffective. Herein, we address these possible etiologies and data that support underlying mechanisms.

Abstract
Objective The transcription factor Specificity protein 1 (Sp1) plays important roles in many critical biological functions; however, its expression and underlying functions in endometriosis remain undefined. Bioinformatics has suggested that Sp1 is potentially regulated by miR-25-3p. This study investigated Sp1 and miR-25-3p expression and their interaction during the pathogenesis of endometriosis. Methods Fifteen women with American Fertility Society stage III/IV ovarian endometriosis and 14 disease-free controls were included. Sp1 expression was detected by qPCR, immunohistochemistry, and western blotting. Using both bioinformatics and genetics, we identified that Sp1 was a potential target of miR-25-3p. Then, the relationship between miR-25-3p and Sp1 was investigated by knockdown and overexpression experiments. Results Sp1 mRNA and protein levels were increased in ectopic and eutopic endometrium compared with normal endometrium samples, with the highest expression in ectopic endometrium samples. In vitro experiments and luciferase reporter assays demonstrated that Sp1 was upregulated when miR-25-3p was depleted and that Sp1 was a direct target of miR-25-3p, respectively. Conclusions Our study revealed increased Sp1 expression in ovarian endometriosis and subsequently demonstrated that miR-25-3p directly targets Sp1. This suggests a novel miRNA/Sp1 pathway in the pathogenesis of endometriosis, which should be further explored for other potential therapeutic targets.

Abstract
Objective: Gynaecologic benign diseases such uterine fibroids share similar pathogeneses with endometrial and ovarian cancers. Whether a history of uterine fibroids increases the risk of developing endometrial or ovarian cancers is controversial, due to uterine fibroids was self-reported in those studies. Methods: In our current case-control study, 268 women with endometrial cancer and 108 women with ovarian cancer were included. In addition, 500 women without gynaecological cancers were randomly selected as a control group. Uterine fibroids in both groups were clinically diagnosed by pelvic examination and ultrasound. Data on age, parity, gravida, stages of cancers and history of uterine fibroids, endometriosis and adenomyosis were collected from hospital database. Results: After adjusted age and parity, the odds of women with history of uterine fibroids or endometriosis were lower in women with endometrial cancer than controls (odds ratio: 0.148, 95% CI: 0.097, 0.225, or 0.360, 95% CI: 0094, 1.381, respectively). The odds of women with a history of uterine fibroids or endometriosis were lower in women with ovarian cancer than controls (odds ratio: 0.141, 95% CI: 0.085, 0.235, or 1.057, 95% CI: 0.377, 2.963, respectively). However, the odds of women with a history of adenomyosis were higher in women with endometrial or ovarian cancers than controls (odd ratio: 3.757, 95% CI: 1.858, 7.599 or 2.341, 95% CI: 1.086, 5.045, respectively). Conclusion: Our observational data suggested that uterine fibroids or endometriosis may be not associated with the increased risk of developing endometrial or ovarian cancer. However, a history of adenomyosis may do.

Abstract
The availability of non-invasive diagnostic tests is an important factor in the renewed interest in adenomyosis, as the disease can now be more accurately mapped in the uterus without a need for hysterectomy. An agreed system for classifying and reporting the condition will enhance our understanding of the disease and is envisaged to enable comparison of research studies and treatment outcomes. In this review, we assess previous and more recent attempts at producing a taxonomy, especially in view of the latest proposal for subdivision of adenomyosis into an internal and an external variant. In this context, we also explore the uncertainties linked to classifying involvement of the uterovesical pouch, the pouch of Douglas and lesions in the outer myometrium. Two opposing hypotheses are forwarded to explain the pathogenesis of these variants, namely that disease localized in these areas originates from an invasion by uterine adenomyosis of peritoneal organs; alternatively, that lesions present in the outer myometrium originate from peritoneal endometriosis. At the root of debates around these opposing theories of pathogenesis is fragmentary evidence. Because of the limitations of currently available evidence, and until this issue is resolved, broad agreement on a hypothesis to underpin any proposed classification is unlikely.

Abstract
Pregnancy and neonatal outcomes in women diagnosed with endometriosis were investigated using data collected from the Korea National Health Insurance Claims Database and the National Health Screening Program for Infants and Children. A total of 3,778,561 women who gave birth between 2007 and 2015 were identified, and 1,938,424 primiparous women and their newborns were included in this study. Women with a diagnosis of endometriosis had a significantly higher incidence of multiple pregnancy, cesarean section, breech presentation, postpartum hemorrhage, placental abruption, placenta previa, and stillbirth than women without endometriosis (P < 0.0001). The rates of preterm birth and low birth weight were also increased in women with endometriosis (P < 0.0001). After adjusting for age, the estimated risks of these outcomes remained significant. Women previously diagnosed with endometriosis have an increased risk of adverse pregnancy and neonatal outcomes. Particular attention and information regarding these conditions should be provided to women with endometriosis during the preconception or antenatal periods.

Abstract
Endometriosis may compromise the physiological course of pregnancy. The aim of this prospective observational study was to evaluate whether endometriosis causes a higher prevalence of obstetric and neonatal complications as well as a higher risk of caesarean section and to detect a possible correlation between the presence, type, and location of endometriosis and obstetric complications, previous surgery, and pregnancy outcome, as well as the influence of pregnancy on the course of the disease. We compared two cohorts of women with spontaneous pregnancy, with and without endometriosis. Obstetric and neonatal outcomes, mode of delivery, presence, type, and location of endometriotic lesions and the effect of pregnancy on the disease were analyzed. A total of 425 pregnancies were evaluated: 145 cases and 280 controls. Patients with endometriosis showed a higher incidence of miscarriage, threatened miscarriage, threatened preterm labor, preterm delivery, placental abruption, and a higher incidence of caesarean section. A significant correlation with pregnancy-induced hypertension and preeclampsia was found in the presence of adenomyosis. No difference in fetal outcome was found. One case of hemoperitoneum during pregnancy was observed. Pregnancy in women with endometriosis carries a higher risk of obstetric complications, such as miscarriage, threatened miscarriage, preterm labor, preterm birth, and a higher caesarean section rate. Endometriosis does not seem to influence fetal well-being.

Abstract
Considerable efforts have been invested to elucidate the potential mechanisms involved in the physiopathology of endometriosis. However, to date, prior research has not been conclusive. This research has examined one particular mechanism, i.e., the effect of ADAR1 on endometriosis lesions. Eutopic endometrium was collected from women with (n = 25) and without endometriosis (n = 25), respectively. The expression of ADAR1 mRNA was measured based on quantitative real-time polymerase chain reactions (RT-qPCR). Both Western blot and immunohistochemistry were performed to establish ADAR1 protein expression levels. The results indicated that ADAR1 mRNA and proteins were significantly greater in the eutopic endometrium of the women with endometriosis, compared to the women without (P < 0.05). The Cell Counting Kit-8 (CCK-8) and EdU method were conducted to examine the effect of ADAR1 on cell viability and proliferation in eutopic endometriosis cells. A transwell assay was also used to detect the role of ADAR1 in the invasion of endometrial cells. The results obtained showed that ADAR1 promoted endometrial cell viability, proliferation, and invasion (P < 0.05). This informed our conclusion that the ADAR1 gene is upregulated in endometriosis, potentially paying a pivotal role in the physiopathology of endometriosis.

Abstract
Uterine adenomyosis is a benign disorder that often co-occurs with endometriosis and/or leiomyoma, and impairs quality of life. The genomic features of adenomyosis are unknown. Here we apply next-generation sequencing to adenomyosis (70 individuals and 192 multi-regional samples), as well as co-occurring leiomyoma and endometriosis, and find recurring KRAS mutations in 26/70 (37.1%) of adenomyosis cases. Multi-regional sequencing reveals oligoclonality in adenomyosis, with some mutations also detected in normal endometrium and/or co-occurring endometriosis. KRAS mutations are more frequent in cases of adenomyosis with co-occurring endometriosis, low progesterone receptor (PR) expression, or progestin (dienogest; DNG) pretreatment. DNG's anti-proliferative effect is diminished via epigenetic silencing of PR in immortalized cells with mutant KRAS. Our genomic analyses suggest that adenomyotic lesions frequently contain KRAS mutations that may reduce DNG efficacy, and that adenomyosis and endometriosis may share molecular etiology, explaining their co-occurrence. These findings could lead to genetically guided therapy and/or relapse risk assessment after uterine-sparing surgery.

Abstract
AIM Women with adenomyosis are at higher risk of endometriosis recurrence after surgery. This study was to assess if the lymphatic vessel network drained from the uterus to near organs where endometriosis foci lied. METHODS A prospective, observational study, Canadian Task Force Classification II-2, was conducted at Sacro Cuore Don Calabria Hospital, Negrar, Italy. 104 white women aged 18-43 years were enrolled consecutively for this study. All patients underwent laparoscopy for endometriosis and a tubal dye test was carried out. RESULTS Evidence of dye dissemination through the uterine wall and outside the uterus was noted in 27 patients (26%) with adenomyosis as it permeated the uterine wall and a clear passage of the dye was shown in the pelvic lymphatic vessels regardless whether the tubes were unobstructed. Histological assessment of the uterine biopsies confirmed adenomyosis. CONCLUSION Adenomyosis is characterized by ectatic lymphatics that allow the drainage of intrauterine fluids (the dye and, perhaps, menstrual blood) at minimal intrauterine pressure from the uterine cavity though the lymphatic network to extrauterine organs. Certainly, this may not be the only explanation for endometriosis dissemination but the correlation between the routes of the dye drainage and location of endometriosis foci is highly suggestive.

Abstract
RESEARCH QUESTION How closely related are adenomyotic and endometrial glands? DESIGN In this study, the mRNA and protein database www.proteinatlas.org was searched for proteins expressed predominantly in the endometrial glands. Specificity was tested with tissue microarrays. Biopsy specimens of endometrial, adenomyotic tissue, or both, were collected after surgery from 21 women without endometriosis, 20 women with endometriosis, 18 women with adenomyosis together with endometriosis and 12 women with adenomyosis alone. Tissue expression was analysed by immunohistochemistry. RESULTS Two proteins were identified: calcyphosine (CAPS), and msh homeobox 1 (MSX1). A high abundance and good specificity in endometrial glands were found. Both proteins, CAPS and MSX1, showed a high specificity for endometrium and are both localized in the luminal cells and epithelial cells of the glandular and adenomyotic glands. No significant differences were found between CAPS- and MSX1-positive endometrial glands between cases with and without endometriosis. Also, no cycle-specific different expression was found. Furthermore, a close relationship between the adenomyotic glands and the endometrial glands for CAPS (range 63.0-98.3%) and for MSX1 (range 87.1-99.3%) could be demonstrated. Only 11.2% and 6.8% negative glands for CAPS and MSX1 were identified in all tissues from all patients, respectively; none were negative for both proteins. CONCLUSIONS Taken together, our results show that the protein expression pattern of adenomyosis is nearly identical to those of the endometrium with and without endometriosis, thus suggesting endometrial glands as the main source for adenomyotic glands.

Abstract
Purpose Our study aims to investigate the distribution of pain symptoms and the association between pain symptoms and clinical parameters in patients with adenomyosis. Patients and methods The clinical and pathological data of 291 patients diagnosed with adenomyosis in the Obstetrics and Gynecology Department of Peking Union Medical College Hospital from March 2012 to September 2015 were collected, and analyzed in regard to the pain symptoms. Results The median age at disease onset was 34 years. 71.8% of the patients had pain symptoms (pain group) and 28.2% had no pain symptoms (painless group). Patients with symptoms accompanied by dysmenorrhea accounted for 68%, among which 30.3% were mild, 36.9% were moderate, and 32.8% severe, while 56.1% presented with progressive pain. Through comparison, significant differences were identified between the pain and painless groups with regard to age at diagnosis (P=0.009), age at onset of disease (P=0.008), and level of pre-surgical CA125 (P<0.001), as well as proportion of patients with rectal irritation (P=0.008), elevated CA125 level (P<0.001), thickened myometrial layer (P<0.001) and concurrent endometriosis (P=0.001). In the multivariable analysis, an elevated level of pre-surgical CA125 (P<0.001) and thickened posterior myometrial layer (P=0.023) were both independent risk factors for the morbidity of pain symptoms. Similar results except for the difference in rectal irritation were noticed when we made further comparison between the dysmenorrhea and non-dysmenorrhea groups in adenomyosis patients. Conclusion Our research analyzes the clinical features related to pain symptoms in patients with adenomyosis, which may provide clues for the possible presurgical diagnosis of adenomyosis, as well as references for pain management of adenomyosis.

Abstract
Endometriosis is a chronic inflammatory disease defined as the presence of endometrial tissue outside the uterus, which causes pelvic pain and infertility. This disease should be viewed as a public health problem with a major effect on the quality of life of women as well as being a substantial economic burden. In light of the considerable progress with diagnostic imaging (for example, transvaginal ultrasound and MRI), exploratory laparoscopy should no longer be used to diagnose endometriotic lesions. Instead, diagnosis of endometriosis should be based on a structured process involving the combination of patient interviews, clinical examination and imaging. Notably, a diagnosis of endometriosis often leads to immediate surgery. Therefore, rethinking the diagnosis and management of endometriosis is warranted. Instead of assessing endometriosis on the day of the diagnosis, gynaecologists should consider the patient's 'endometriosis life'. Medical treatment is the first-line therapeutic option for patients with pelvic pain and no desire for immediate pregnancy. In women with infertility, careful consideration should be made regarding whether to provide assisted reproductive technologies prior to performing endometriosis surgery. Modern endometriosis management should be individualized with a patient-centred, multi-modal and interdisciplinary integrated approach.

Abstract
This study presents the postoperative pregnancy rate of women with recurrent endometriosis and evaluates the predictive value of the endometriosis fertility index (EFI) for the pregnancy.A total of 107 women who wished to conceive after surgery for recurrent endometriosis from January 2007 to December 2016 were included. The EFI score was calculated postoperatively. The receiver operator characteristic (ROC) curve was plotted to determine the most promising contributor to predicting pregnancy, and Kaplan-Meier (K-M) analysis was used to estimate the cumulative pregnancy rate (CPR).A total of 61 pregnancies were registered in 58 women and the remaining 49 patients failed to become pregnant. The EFI score was strongly associated with the postoperative fertility prognosis. The CPRs during the first 2 and 3 years postoperatively were 51.86% and 66.38%, respectively, and increased to 71.98% within the first 5 years postoperatively in patients with EFI scores ≥5. However, the CPR was 26.00% during the first 2 years after surgery in individuals with EFI scores <5, and there was no increase in the CRP thereafter.Women suffering from recurrent endometriosis still experienced a probability of natural pregnancy, especially patients with EFI scores ≥5. The EFI score had good predictive power for postoperative pregnancy in these patients.

Abstract
Background and objective: Previous studies did not draw a definitive conclusion about the influence of the role of deep endometriosis (DE) and ovarian endometrioma (OE) as risk factor for developing adverse perinatal outcomes in patients affected by endometriosis. This study aimed to investigate if adverse fetal and maternal outcomes, and in particular the incidence of small for gestational age (SGA) infants, are different in pregnant women with OE versus pregnant women with DE without OE. Material and methods: This study was based on a retrospective analysis of a database collected prospectively. The population included in the study was divided into three groups: patients with OE, patients with DE without concomitant OE, and patients without endometriosis (controls). The controls were matched on the basis of age and parity. Demographic data at baseline and pregnancy outcomes were recorded. Results: There was no statistically significant difference in first trimester levels of PAPP-A, first and mid-pregnancy trimester mean Uterine Artery Doppler pulsatile index, estimated fetal weight centile, and SGA fetuses' prevalence for patients with OE, and those with DE without OE in comparison to health women; moreover, there was no statistically significant difference with regard to SGA birth prevalence, prevalence of preeclampsia, and five-minute Apgar score between these three groups. Conclusions: The specific presence of OE or DE in pregnant women does not seem to be associated with an increased risk of delivering an SGA infant. These data seem to suggest that patients with endometriosis should be treated in pregnancy as the general population, thus not needing a closer monitoring.

Abstract
Endometrial polyps, adenomyosis, and leiomyomas are commonly encountered abnormalities frequently found in both fertile women and those with infertility. The clinician is frequently challenged to determine which of these entities, when found, is likely to impair fertility, and which are "innocent bystanders" unrelated to the problem at hand. Although removing an endometrial polyp may be seen as a relatively benign and safe intervention, myomectomy, and in particular adenomyomectomy, can be substantive surgical procedures, associated with their own potential for disrupting fertility. One of the mechanisms thought to be involved when these entities are contributing to infertility is an adverse impact on endometrial receptivity. Indeed polyps, adenomyosis, and leiomyomas have all been associated with an increased likelihood of abnormal endometrial molecular expressions thought to impair implantation and early embryo development. This review is designed to examine the relationship of these common entities to endometrial receptivity and to identify evidence gaps that should be considered when strategizing research initiatives. It is apparent that we have the tools necessary to fill these gaps, but it will be necessary to approach the issue in a strategic and coordinated fashion. It is likely that we will have to recognize the limitations of imaging alone and look to the evidence-based addition of molecular analysis to provide the individualized phenotyping of disease necessary for patient-specific treatment decisions.

Abstract
BACKGROUND Because of the increased number of diagnosed cases of endometriosis or adenomyosis resulting in infertility, many women require assisted reproductive technology (ART) to become pregnant. However, incidences of obstetric complications are increased for women who conceive using ART. There has been no prospective cohort study examining the influence of endometriosis and adenomyosis on obstetric outcomes after adjusting for the confounding influence of ART therapy. OBJECTIVE This study evaluated the impact of endometriosis and adenomyosis on the incidence of adverse pregnancy outcomes. STUDY DESIGN Data were obtained from a prospective cohort study, known as the Japan Environment and Children's Study (JECS), of the incidence of obstetric complications for women with endometriosis and adenomyosis. The data of 103,099 pregnancies that resulted in live birth or stillbirth or that were terminated through abortion between February 2011 and July 2014 in Japan were included. RESULTS Women with endometriosis or adenomyosis were at increased risk for complications during pregnancy compared to those without a medical history of endometriosis (odds ratio [OR], 1.32; 95% confidence interval [CI], 1.23 to 1.41) or adenomyosis (OR, 1.72; 95% CI, 1.37 to 2.16). Our analysis showed that the adjusted ORs for obstetric complications of pregnant women who conceived naturally or after infertility treatment that did not involve ART therapy were 1.26 (CI, 1.17 to 1.35) for pregnant women with a history of endometriosis and 1.52 (CI, 1.19 to 1.94) for those with a history of adenomyosis. CONCLUSIONS The presence of endometriosis and adenomyosis significantly increased the prevalence of obstetric complications after adjusting for the influence of ART outcomes.

Abstract
The field of endometriosis etiopathogenesis aims to identify the origin of disease in endometrial disorders. Changes in gene and protein expression related to cell adhesion, collagenases, and, mainly, cell cycle regulators have been identified. We set out to analyze the expression of the transcription factor DP-1 (TFDP1) gene, which encodes a protein that controls the G1/S phase passage of the cell cycle, in the endometrium of women with deep infiltrating endometriosis (DIE). Samples of endometrium from both endometriosis-affected women and healthy women were collected, cultured and maintained at the Cell Bank of the Pelvic Pain and Endometriosis Unit of the Federal University of Sao Paulo. This study analyzed five samples from the endometrium cell culture of healthy patients (i.e. no pelvic disease, as determined by means of laparoscopic tubal ligation) and six samples from women diagnosed with DIE. Samples were evaluated for TFDP1 gene expression by real-time PCR. We observed a downregulation of TFDP1 in the endometrium cells of women with DIE when compared to the control (a fold-change of -2.05, p value=.011). The TFDP1 gene is part of the cell cycle pathway, but its function is not yet clear. Additional studies are necessary to clarify the function of TFDP1 in endometriosis etiopathogenesis.

Abstract
Objective To investigate the effect of human chorionic gonadotropin (hCG) intrauterine injection before frozen–thawed embryo transfer (FET) in women with endometriosis. Methods This retrospective cohort study included 45 women with endometriosis who underwent hCG intrauterine injection before FET; each woman was matched with three patients with endometriosis who did not receive hCG intrauterine injection (controls). Data on pregnancy and prenatal outcomes were extracted from medical records and compared. Results Patients in the hCG intrauterine injection group had significantly higher rates of pregnancy and clinical pregnancy (64.4% and 57.8%, respectively) than controls (47.4% and 39.3%, respectively). Neonatal birth weight for both singletons and twins was significantly higher in the hCG group (3486 ± 458 g and 2710 ± 437 g, respectively) than in the control group (3195 ± 401 g and 2419 ± 370 g, respectively). Conclusion Pregnancy rate, clinical pregnancy rate, and birth weight were improved in women with endometriosis who underwent intrauterine hCG injection compared with those who did not receive hCG before FET.

Abstract
BACKGROUND Studies on the impact of adenomyosis and its pregnancy complications have yielded conflicting results. OBJECTIVE To determine the likelihood of adverse pregnancy outcomes among women with adenomyosis relative to women without adenomyosis. SEARCH STRATEGY PubMed, Embase, Scopus, and Web of Science were searched for studies published up to June 15, 2018. SELECTION CRITERIA Observational studies with medically confirmed pregnancy outcomes as endpoints. DATA COLLECTION AND ANALYSIS Two researchers independently screened and selected relevant studies. Dichotomous data for all adverse pregnancy outcomes were expressed as an odds ratio (OR) with 95% confidence interval (CI), and combined in a meta-analysis by using a random-effects model. MAIN RESULTS Six studies (322 cases and 9420 controls) were eligible for inclusion in the meta-analysis. Women with adenomyosis had an increased likelihood of preterm birth (OR, 3.05; 95% CI, 2.08-4.47; P˂0.001), small for gestational age (OR, 3.22; 95% CI, 1.71-6.08; P˂0.001), and pre-eclampsia (OR, 4.35; 95% CI, 1.07-17.72; P=0.042). CONCLUSION Adenomyosis seems to have a detrimental impact on pregnancy outcomes, resulting in a higher likelihood of preterm birth, small for gestational age, and pre-eclampsia.

Abstract
Adenomyosis is a benign uterine disorder in which endometrial glands and stroma are pathologically demonstrated in the uterine myometrium and it is considered a specific entity in the PALM-COEIN FIGO (polyp; adenomyosis; leiomyoma; malignancy and hyperplasia; coagulopathy; ovulatory dysfunction; endometrial; iatrogenic; and not yet classified - International Federation of Gynecology and Obstetrics) classification of causes of abnormal uterine bleeding (AUB). Although it has always been considered the classic condition of multiparous women over 40 years old who have pain and heavy menstrual bleeding, diagnosed at hysterectomy, the epidemiological scenario has completely changed. Adenomyosis is increasingly identified in young women with pain, AUB, infertility, or no symptoms by using imaging techniques such as transvaginal ultrasound and magnetic resonance. However, there is no agreement on the definition and classification of adenomyotic lesions from both the histopathology and the imaging point of view, and the diagnosis remains difficult and unclear. A uniform and shared reporting system needs to be implemented in order to improve our understanding on imaging features, their relationship with pathogenic theories, and their importance in terms of clinical symptoms and response to treatment. In fact, adenomyosis pathogenesis remains elusive and not a single theory can explain all of the different phenotypes of the disease. Furthermore, adenomyosis often coexists with other gynecological conditions, such as endometriosis and uterine fibroids, increasing the heterogeneity of available data. Treatment requires a lifelong management plan as the disease has a negative impact on quality of life in terms of menstrual symptoms, fertility, and pregnancy outcome and has a high risk of miscarriage and obstetric complications.

Abstract
Ulipristal acetate (UPA) is used for medical treatment of uterine fibroids. The aim of this study was to describe the effects on painful symptoms and the sonographic uterine modifications in patients with adenomyosis erroneously treated with UPA. This is an observational study on six women affected by adenomyosis and treated with three months of UPA (5 mg/24h). The baseline ultrasonography (US) was not performed at out center nor was the diagnosis of fibroids. The patients came to our attention after the treatment with UPA, prescribed by an external physician. During our post-treatment scan we found aspects of adenomyosis, while no fibroids were detected. Symptoms, myometrial and endometrial ultrasound features were evaluated. All patients reported an increase in pelvic pain. At US evaluation intramyometrial cystic areas were found in all six cases (100%). All patients showed an enhancement of adenomyosis features.The intra-myometrial cysts appeared enlarged and the vascularization enhanced when compared to the images of the pretreatment scan. In patients with adenomyosis treated with UPA due to an erroneous diagnosis of uterine fibroids we observed a worsening of the US features of adenomyosis and of the painful symptoms.

Abstract
BACKGROUND Endometriosis is thought to affect the effectiveness of ART by an increased risk of miscarriage. We aimed to investigate the impact of endometriosis in women achieving singleton pregnancies through IVF fresh cycles and risk of miscarriage. METHODS This retrospective cohort study included all women undergoing a first IVF cycle and achieving singleton pregnancies after fresh embryo transfer in a tertiary university hospital reproductive medical center between January 2008 and June 2016. Women with endometriosis were compared with women with no endometriosis. Women in the endometriosis group were all with a history of laparoscopy or laparotomy for endometriosis and/or with ovarian endometrioma. The control group was matched 1:2 according to age and study period. RESULTS Among the cohort, we identified 1006 women with endometriosis as study group and 2012 unaffected women matched in a 1:2 ratios as control group. The miscarriage rate between women with and without endometriosis was similar (22.4 and 20.1%, P = 0.085). The odds ratio after adjusting for the risk factors for miscarriage was 1.14 (95% confidence interval 0.95-1.37). In the study group, the women with and without endometrioma did not show a significant risk of miscarriage, (19.8 and 23.8%, P = 0.152, OR 0.79, 95% CI 0.58-1.09). The miscarriage rate in women with endometrioma ≥30 mm (37.3 ± 7.1 mm) and < 30 mm (19.3 ± 5.5 mm) was not significantly different, (24.7 and 18.5%, P = 0.229, OR 1.44, 95% CI 0.79-2.63). After adjustment for risk factors for miscarriage, the presence of endometrioma and the size of endometrioma, regression model confirmed no significant increase for the risk of miscarriage in the subgroup analyses. CONCLUSIONS The risk of miscarriage did not statistically increase in women with endometriosis who achieved pregnancy through IVF fresh cycles.

Abstract
Abnormal uterine bleeding (AUB) is a common condition that leads to increased health care costs and decreased quality of life. A systematic approach to AUB evaluation can simplify management and enhance women's well-being. Abnormal uterine bleeding describes any variation from normal bleeding patterns in nonpregnant, reproductive-aged women beyond menarche lasting for at least 6 months. Ambiguous and inconsistent use of terminology and definitions to characterize AUB in the past decades necessitated a new, consensus-based approach to nomenclature and AUB evaluation. This led to the International Federation of Gynecology and Obstetrics (FIGO) System 1 in 2007, which standardized nomenclature, set parameters, and defined normal and abnormal bleeding based on the 5th to 95th percentile data from available large-scale epidemiologic studies. FIGO System 1, endorsed by several national and international societies, improved worldwide communication among educators, clinicians, and researchers. FIGO System 2, published in 2011, focused on classifications of AUB etiology into structural and nonstructural entities using the PALM-COEIN (polyp[s], adenomyosis, leiomyoma, malignancy, coagulopathy, ovulatory dysfunction, endometrial disorders, iatrogenic, and not yet classified) classification system. The PALM-COEIN classification is facilitated by a complete patient history combined with appropriate imaging, histopathologic analysis, or laboratory evaluation to ensure accurate diagnostic and treatment approaches to AUB. Herein we present the systematic evaluation of AUB.

Abstract
Emerging studies showed that lncRNA taurine upregulated 1 (TUG1) plays important roles in diverse biological processes. However, there is no previously published research reporting the regulatory role of lncRNAs in the progression of adenomyosis. In the present study, we found that TUG1 is upregulated in human adenomyosis, and the overexpression of TUG1 is associated with the transcription factor early growth response 1 (EGR1). Functionally, the knockdown of TUG1 inhibited adenomyotic epithelial cell migration and invasion but not growth. The mechanistic experiments demonstrated that the function of TUG1 in adenomyotic epithelial cell invasion is, at least in part, through recruiting the enhancer of zeste homolog 2 (EZH2) to the promoter of tissue inhibitor of metalloproteinases 2 (TIMP2) and negatively regulating its expression. Our study demonstrated that TUG1 promotes the migration and invasion of human adenomyotic epithelial cells, and EGR1/TUG1/EZH2/TIMP2 may be a potential therapeutic target for adenomyosis.

Abstract
Adenomyosis is a benign uterine condition affecting women at various ages with different symptoms. The management of these patients is still controversial. Few clinical studies focusing on medical or surgical treatment for adenomyosis have been performed. No drug is currently labelled for adenomyosis and there are no specific guidelines to follow for the best management. Anyhow, medical treatments are effective in improving symptoms (pain, abnormal uterine bleeding and infertility). The rationale for using medical treatment is based on the pathogenetic mechanisms of adenomyosis: sex steroid hormones aberrations, impaired apoptosis, and increased inflammation. Several nonhormonal (i.e., nonsteroidal anti-inflammatory drugs) and hormonal treatments (i.e., progestins, oral contraceptives, gonadotropin-releasing hormone analogues) are currently used off-label to control pain symptoms and abnormal uterine bleeding in adenomyosis. Gonadotropin-releasing hormone analogues are indicated before fertility treatments to improve the chances of pregnancy in infertile women with adenomyosis. An antiproliferative and anti-inflammatory effect of progestins, such as dienogest, danazol and norethindrone acetate, suggests their use in medical management of adenomyosis mainly to control pain symptoms. On the other hand, the intrauterine device releasing levonorgestrel resulted is extremely effective in resolving abnormal uterine bleeding and reducing uterine volume in a long-term management plan. Based on new findings on pathogenetic mechanisms, new drugs are under development for the treatment of adenomyosis, such as selective progesterone receptor modulators, aromatase inhibitors, valproic acid, and anti-platelets therapy.

Abstract
OBJECTIVES Several studies have investigated the correlation between endometriosis and adverse pregnancy and perinatal outcomes. However, the role of adenomyosis as a risk factor for adverse perinatal outcome in women with endometriosis has yet to be established. The aim of this study was to explore if fetal and maternal outcomes, in particular the incidence of a small-for-gestational-age (SGA) infant, are different in pregnant women with endometriosis only from in those with the concomitant presence of diffuse or focal adenomyosis. METHODS This was a retrospective analysis of data collected prospectively during a 3-year period. We included 206 pregnant women with endometriosis: 148 (71.8%) with endometriosis only, 38 (18.4%) with focal adenomyosis and 20 (9.7%) with diffuse adenomyosis. Adenomyosis was diagnosed using ultrasonography and was classified as focal or diffuse. The study included patients who conceived spontaneously or by an assisted reproductive technique. Demographics, ultrasound variables and outcome were compared between women with endometriosis only and those with diffuse and those with focal adenomyosis. Logistic regression analysis was performed to assess the association of variables with SGA at birth in women with diffuse and those with focal adenomyosis. RESULTS The three groups were similar in demographic characteristics (age, body mass index, mode of conception). Patients with diffuse adenomyosis compared with those with endometriosis only had significantly lower pregnancy-associated plasma protein A (0.61 vs 0.88 multiple of the median, P < 0.001), higher mean uterine artery pulsatility index in the first (2.23 vs 1.67, P < 0.001) and second (1.30 vs 0.94, P < 0.001) trimesters of pregnancy, and higher incidence of SGA (40% vs 10.8%, P < 0.001). No statistically significant differences were found in patients with focal adenomyosis compared with those with endometriosis only. Logistic regression analysis demonstrated that diffuse adenomyosis (odds ratio = 3.744; 95% CI, 1.158-12.099; P = 0.027) was the only independent risk factor for SGA. CONCLUSIONS The presence of diffuse adenomyosis in pregnant women with endometriosis is strongly associated with delivery of a SGA infant. Women with diffuse adenomyosis should be treated as being at high risk of placental dysfunction, and these pregnancies might therefore need closer monitoring. Copyright © 2017 ISUOG.

Abstract
BACKGROUND Differentially expressed microRNAs (miRNAs) and their target mRNAs may lead to alterations in normal physiological status of the tissues and initiate pathological processes. The aim of this study was to investigate the expression of the most relevant miRNAs in the eutopic endometrial tissue during the window of implantation in women with endometriosis-related infertility. METHODS In the study, 76 infertile women with a regular menstrual cycle were recruited from the Center for Reproductive Medicine, Peking University Third Hospital between January 2014 and June 2016. We performed a combined messenger RNA and miRNA microarray and bioinformatics analysis of eutopic endometrium in 6 women with and without endometriosis-related infertility at the time of implantation window. Quantitative real-time polymerase chain reaction arrays were utilized to examine the expression levels of selected miRNAs (from 35 patients with endometriosis and 35 disease-free individuals at different menstrual stages). RESULTS Five differentially expressed miRNAs (miR-142-5p, miR-146a-5p, miR-1281, miR-940, and miR-4634) were significantly upregulated, whereas miR-543 was significantly downregulated in the eutopic endometrium during the window of implantation in patients with endometriosis. Further analysis showed that miR-543 was significantly upregulated at the peri-implantation phase compared with that at proliferative phase in the endometrium of disease-free patients (P < .05). However, the expression level of miR-543 was significantly decreased in patients with endometriosis (P < .05), especially downregulated at the window of implantation phase (P < .05). CONCLUSIONS miR-543 plays an important role during embryo implantation process and is associated with endometrial receptivity. Downregulation of miR-543 may affect embryo implantation, resulting in the pathogenesis of endometriosis-related infertility.

Abstract
Endometriosis is a common inflammatory disease characterized by the presence of tissue outside the uterus that resembles endometrium, mainly on pelvic organs and tissues. It affects ~5-10% of women in their reproductive years - translating to 176 million women worldwide - and is associated with pelvic pain and infertility. Diagnosis is reliably established only through surgical visualization with histological verification, although ovarian endometrioma and deep nodular forms of disease can be detected through ultrasonography and MRI. Retrograde menstruation is regarded as an important origin of the endometrial deposits, but other factors are involved, including a favourable endocrine and metabolic environment, epithelial-mesenchymal transition and altered immunity and inflammatory responses in genetically susceptible women. Current treatments are dictated by the primary indication (infertility or pelvic pain) and are limited to surgery and hormonal treatments and analgesics with many adverse effects that rarely provide long-term relief. Endometriosis substantially affects the quality of life of women and their families and imposes costs on society similar to those of other chronic conditions such as type 2 diabetes mellitus, Crohn's disease and rheumatoid arthritis. Future research must focus on understanding the pathogenesis, identifying disease subtypes, developing non-invasive diagnostic methods and targeting non-hormonal treatments that are acceptable to women who wish to conceive.
