Endometriosis and breast cancer- love or hate?
Many studies have been conducted to investigate the relationship between endometriosis and breast cancer, but no definitive conclusion has been reached yet. In the study co-authored by Yan and Li et al, endometriosis-related GWAS data was used to determine the causal relationship between breast cancer risk and endometriosis (EMS). The study used a Mendelian Randomization approach to conduct the analysis. The results showed that for every standard deviation increase in endometriosis, the risk of breast cancer decreased by 5.0%. Estrogen…

Endometriosis as a "syndrome" made out of different clusters
Endometriosis has been classified according to surgical findings. In the study conducted by Antonio Sarria-Santamera et al., the authors aimed to classify the patients with their comorbidities. The study explored the multidimensionality of endometriosis using cluster analysis. It categorizes women with endometriosis into six clusters based on their comorbidities: clusters 1 to 6 where cluster 1 (less comorbidity), cluster 2 (anxiety and musculoskeletal disorders), cluster 3 (type 1 allergy or immediate hypersensitivity), cluster 4 (multiple morbidities), cluster 5 (anemia and…

The Molecular Mechanisms of how herbal medicine Actaea racemosa modulates Endometriosis Progression
Increased proliferation, dysregulated apoptosis, and a pro-inflammatory and oxidative environment are the hallmarks of endometriosis. In the article published in the Journal of Molecular Sciences, penned by Livia Interdonato et al, the molecular mechanisms of the extract from a plant named "Actaea racemosa" administration in endometriosis were examined, with a particular emphasis on pain, oxidative stress, and proliferation. High-frequency ultrasound analysis was used to track the progression of the disease, and Actaea racemosa treatment markedly reduced hyperproliferation. The administration improved apoptosis…

Autoimmune Disorders in Women with Endometriosis May Impair Embryo Implantation
The retrospective study by Noemi Salmeri reports the effect of concomitant autoimmune disorders on the ability of the endometrium to support embryo implantation in women with endometriosis who underwent assisted reproductive technology (ART) treatments. The study involved 600 women with endometriosis, with 150 having concomitant autoimmune disorders and 450 without. The participants received ART treatments, which included ovarian stimulation, oocyte retrieval, fertilization, and embryo transfer. The primary outcome of the study was the cumulative clinical pregnancy rate, characterized as pregnancy…

Getting help from water to replace colonoscopy and MRI for the diagnosis of deep bowel endometriosis.
This retrospective study by Martyna Masternak et al. discusses the use of rectal water contrast transvaginal ultrasound (RWC-TVS) as a tool for assessing deep bowel endometriosis. The study explains how the procedure is minimally invasive, and how it involves filling the rectum with water and using transvaginal ultrasound to visualize the bowel. This technique allows for the detection and mapping of "deep bowel endometriosis" lesions, which can then be used to guide surgical treatment and might replace MRI and colonoscopy.…

Spheroids: 3D-mini-models for Understanding Endometriosis
The pathogenesis of endometriosis is not fully understood, and there is a need for better models to study the disease. Spheroids are 3D clusters of cells that mimic the structure and function of endometrial tissue. These mini models have several advantages over traditional 2D cell cultures, including providing a more physiologically relevant environment for studying cell behavior. Spheroids have the potential to be used as models for a variety of diseases, including endometriosis. In the article led by Dr. Fazleabas a…

Unraveling the Role of Vascularization in Deep Endometriosis
The systematic review by Simon G. Powell published in the journal Cells, analyzed 15 studies including 1125 women with deep infiltrative endometriosis up to March 2023 in several databases and found that angiogenesis plays a crucial role in the growth and spread of endometrial tissue outside of the uterus. VEGF, namely Vascular Endothelial Growth Factor, is a key regulator of angiogenesis and has been implicated in the development of deep endometriosis. VEGF expression has been shown to be upregulated in…

Novel Diagnostic Strategies for the Detection of Malignant Transformation of Endometriosis
Endometriotic implants can grow on various organs and tissues in the pelvis, leading to pain, infertility, and other symptoms. Most cases of endometriosis are benign and there is a small risk of malignant transformation. The review conducted by Dr. Hiroshi Kobayashi from Nara Medical University, Japan, provides an overview of the current understanding of the malignant transformation of endometriosis, its clinicopathological characteristics, and molecular features. The most common type of malignancy that arises from endometriosis is clear cell carcinoma, followed…

Exploring the Potential Impact of Prenatal Testosterone on Endometriosis
The exact causes of endometriosis still remain uncertain but emerging evidence suggests that prenatal factors may contribute to its development. In the review study by Bernard J Cresp et al, the authors discuss the hormonal environment during prenatal development and propose that exposure to low testosterone levels could be a potential risk factor for endometriosis later in life. They review existing research studies that provide support for this hypothesis, including animal studies and clinical observations. The article further explores the…

Deep Infiltrating Endometriosis and Adenomyosis have different genetic pathways
It is still not defined whether adenomyosis is also a deep endometriosis component or not. In the study conducted by Marshall et al, the researchers compared the gene expression patterns between deep infiltrating endometriosis (DIE) and adenomyosis uteri in order to identify potential dysregulation of oncogene pathways. The researchers utilized gene expression profiling techniques to analyze tissue samples from patients diagnosed with either DIE or adenomyosis. After collecting the tissue samples from patients diagnosed with either DIE or adenomyosis during…

A self-diagnostic tool that predicts the likelihood of endometriosis
Early diagnosis and treatment of endometriosis are crucial for preventing these negative outcomes, but the disease is often difficult to diagnose due to a lack of specific symptoms and reliable diagnostic tests. Goldstein et al. aimed to develop a machine-learning model that could predict the presence of endometriosis in women based on self-reported symptoms alone. The authors collected data from 1,592 women who completed a survey of symptoms related to endometriosis and underwent diagnostic laparoscopy to confirm the presence or…

The bigger the uterus, the more painful the dysmenorrhea even if you don’t have endometriosis.
The literature finds no correlation between ultrasound or perioperative findings and pain intensity. Thus, a tool to predict pain intensity will ease the choice for proper treatments and follow-ups. In the study led by Dr. Zhao et al., the ultrasonographic measurements of the uterus have been compared with operative findings and pain (VAS) scales of women with and without endometriosis. Reproductive-age women who applied for abdominal surgery have been included. Demographic data and VAS scales for the menstrual pain intensity…
