nnU-Net based segmentation and 3D reconstruction of uterine fibroids with MRI images for HIFU surgery planning.

High-Intensity Focused Ultrasound (HIFU) ablation represents a rapidly advancing non-invasive treatment modality that has achieved considerable success in addressing uterine fibroids, which constitute over 50% of benign gynecological tumors. Preoperative Magnetic Resonance Imaging (MRI) plays a pivotal role in the planning and guidance of HIFU surgery for uterine fibroids, wherein the segmentation of tumors holds critical significance. The segmentation process was previously manually executed by medical experts, entailing a time-consuming and labor-intensive procedure heavily reliant on clinical expertise. This study introduced deep learning-based nnU-Net models, offering a cost-effective approach for their application in the segmentation of uterine fibroids utilizing preoperative MRI images. Furthermore, 3D reconstruction of the segmented targets was implemented to guide HIFU surgery. The evaluation of segmentation and 3D reconstruction performance was conducted with a focus on enhancing the safety and effectiveness of HIFU surgery. Results demonstrated the nnU-Net's commendable performance in the segmentation of uterine fibroids and their surrounding organs. Specifically, 3D nnU-Net achieved Dice Similarity Coefficients (DSC) of 92.55% for the uterus, 95.63% for fibroids, 92.69% for the spine, 89.63% for the endometrium, 97.75% for the bladder, and 90.45% for the urethral orifice. Compared to other state-of-the-art methods such as HIFUNet, U-Net, R2U-Net, ConvUNeXt and 2D nnU-Net, 3D nnU-Net demonstrated significantly higher DSC values, highlighting its superior accuracy and robustness. In conclusion, the efficacy of the 3D nnU-Net model for automated segmentation of the uterus and its surrounding organs was robustly validated. When integrated with intra-operative ultrasound imaging, this segmentation method and 3D reconstruction hold substantial potential to enhance the safety and efficiency of HIFU surgery in the clinical treatment of uterine fibroids.

Challenging Surgical Management of Giant Uterine Leiomyomas With Ileal Resection: A Clinical Case Study.

Uterine fibroids, or leiomyomas, are common benign tumors of the uterus, generally asymptomatic but potentially causing severe symptoms and complications in some cases, as demonstrated in this report. This case presents significant management challenges due to the fibroids' size, number, and location, including an unusual complication involving adhesion to the ileum. A 40-year-old female with a history of P2L1D1 and no significant comorbidities presented with three months of progressive abdominal pain and a rapidly enlarging mass resembling a 30- to 32-week gravid uterus and heavy menstrual bleeding. Clinical findings included severe anemia with a hemoglobin level of 5.5 g/dL. Imaging studies revealed a bulky uterus with numerous multilobulated, well-defined, solid, hypoechoic fibroids subserosally and intramurally, raising suspicions of sarcomatous conversion. The patient underwent a laparotomy, which involved the resection of multiple large subserosal fibroids and a total abdominal hysterectomy, necessitated by extensive uterine distortion and the patient's preference against fertility preservation. A significant intraoperative discovery was the adhesion of fibroids to the ileum, which required bowel resection and anastomosis. This case emphasizes the complexity of managing extensive uterine fibroids, highlighting the need for thorough preoperative assessment, preparation for potential intraoperative complications, and the importance of a multidisciplinary surgical approach. The successful management and uneventful recovery underscore the effectiveness of proactive and comprehensive surgical intervention in cases with significant fibroid burden and associated anatomical challenges.

The Uterus Keeps the Score: Black Women Academics' Insights and Coping with Uterine Fibroids.

Few studies examine how high-achieving Black women navigate chronic reproductive health morbidities. Black women are disproportionately more likely to experience uterine fibroids, with earlier onset and more severe symptoms. This study leverages a national mixed-methods data set of Black women academics to examine how they describe symptomatic fibroids impacting their careers and lives. We find that participants (1) actively coped by engaging in superwoman schema, (2) postponed treatment due to the demands of their tenure-track position, and (3) normalized pain. Our findings suggest a potentially high prevalence of uterine fibroids among Black women faculty, that symptomatic fibroids were an impediment to some women's careers, and that women with symptomatic fibroids often identified expectations of their careers as an impediment to seeking timely treatment. We provide insights for how highly educated, successful Black women cope and navigate career stress coupled with challenges resulting from chronic reproductive health morbidities.

Sonographic features of uterine fibroids that predict the ablation rate and efficacy of high-intensity focused ultrasound.

Objective: This study aimed to identify the sonographic indicators that predict the ablation rate and efficiency of uterine fibroids during high-intensity focused ultrasound (HIFU) treatment. Methods: In this retrospective study, we analyzed the clinical data of patients with uterine fibroids who underwent HIFU treatment at Fujian Provincial Hospital between April 2019 and April 2022. Routine abdominal ultrasound examinations were performed to observe potential indicators before the HIFU treatment. After the treatment, enhanced magnetic resonance imaging (MRI) examination was performed within 2 weeks. The fibroid and non-perfused volumes (NPV) were determined, and the ablation rate and energy efficiency factor (EEF) were calculated. Results: A total of 75 patients (124 uterine fibroids) were included in this study. Uterine fibroids with a larger volume, high echogenicity, elliptical/diffuse leaf shape, and a posterior attenuation band had a higher HIFU ablation rate (p<0.05). Uterine fibroids with a larger volume and high echogenicity and without necrotic areas had a lower EEF (p<0.05). Multiple comparisons between fibroid types revealed statistically significant differences in EEF between subserosal and submucosal fibroids (p < 0.05) and between subserosal and mixed-type fibroids (p < 0.05). However, no statistically significant difference was observed between mixed-type and submucosal fibroids. The HIFU ablation rate and EEF showed no significant differences based on location within the wall and blood flow within the fibroids. Conclusion: Sonographic features of uterine fibroids can predict the rate and efficiency of HIFU ablation, providing useful guidance in selecting appropriate treatment for patients.

Uterine fibroids and non-informative cell-free DNA screening results.

OBJECTIVE: Uterine fibroids are monoclonal tumors, which are often genetically abnormal and associated with false-positive genome-wide cell-free DNA (cfDNA) screening results, particularly when large. It is plausible that fibroids may also increase the risk of cfDNA failure by affecting fetal fraction or due to their genetic anomalies confounding cfDNA algorithms. We aimed to investigate a possible association between fibroids and cfDNA non-informative results. METHODS: This was a retrospective cohort study of women undergoing cfDNA screening for fetal chromosomal abnormalities between 2013 and 2020, comparing pregnancies with vs without uterine fibroids recorded on any obstetric ultrasound before 24 weeks' gestation. Univariable and multivariable logistic regression models were used to investigate the association between fibroids and cfDNA failure, adjusting for gestational age, maternal age, weight and height at blood sampling, mode of conception, multiple gestation and test platform (chromosome-selective or genome-wide). Analyses were stratified according to the number of fibroids and total fibroid volume. The impact of fibroids on fetal fraction was assessed using linear regression, adjusting for the same covariates. RESULTS: Among 19 818 pregnancies undergoing cfDNA screening, fibroids were reported in 2038 (10.28%) and cfDNA failure at the first screening attempt occurred in 228 (1.15%) pregnancies. Non-informative results occurred in 1.96% of pregnancies with fibroids and 1.06% of pregnancies without fibroids (adjusted odds ratio (aOR), 2.40 (95% CI, 1.65-3.48)). The risk of failure in the first screening attempt increased progressively with the number of fibroids (aOR, 5.05 (95% CI, 2.29-11.13) in women with four or more fibroids) and total fibroid volume, with greater than a 5-fold and 14-fold increase in risk among women with fibroid volumes of 100.1-400 mL (aOR, 5.52 (95% CI, 2.30-13.25)) and > 400 mL (aOR, 14.80 (95% CI, 4.50-48.69)), respectively. Although test failure was more common with chromosome-selective than genome-wide screening, fibroids similarly increased the risk of failure of both screening platforms. Compared to pregnancies without fibroids, those with fibroids had a fetal fraction on average 0.61% lower (adjusted mean difference, -0.61% (95% CI, -0.77% to -0.45%)). CONCLUSION: Uterine fibroids are associated with lower fetal fraction and an increased risk of cfDNA screening failure. The strength of this association increases with increasing fibroid number and volume. © 2024 The Author(s).

The Differential Diagnosis of Abdominal Mass: A Case of Uterine Leiomyoma.

The most common benign neoplastic uterine tumors that grow monoclonally from the smooth muscle cells of the uterus are uterine fibroids or leiomyomas, which may occur as a single lesion or as multiple lesions with variation in size from microscopic to large macroscopic extent. The majority are diagnosed in the preclinical routine reliably, despite challenges due to the possibility of multiple differential diagnoses. Hence, this report highlights a case of a postmenopausal female of 53-year-old working as a staff nurse at the same hospital and who visited the outpatient department of obstetrics and gynecology with chief complaints of pain in the right side of the abdomen for four hours (presentation similar to that of appendicitis). Per abdomen examination resulted in a non-tender mass with flank fullness and firmness with a smooth surface and approachable lower border. It clinically appeared as a large uterine fibroid. The built of the patient was obese due to which neither the patient nor relatives were ever able to make out any evident symptoms. The diagnostic investigation involved a magnetic resonance imaging (MRI) that confirmed the diagnosis of two parity with both living, and two were aborted (P2L2A2) with uterine fibroid. The management of the fibroid consisted of exploratory laparotomy along with a hysterectomy and bilateral salpingo-oophorectomy. The intraoperative findings and frozen section report confirmed the presence of benign uterine leiomyoma. Therefore, the utilization of physical examinations and diagnostic tests may assist in preventing a delay in the detection and management of curable conditions such as fibroids, which can be treated without complications with surgery.

Systematic review and meta-analysis of current evidence in uterine artery embolization vs myomectomy for symptomatic uterine fibroids.

This review compares the efficacy of Uterine Artery Embolization (UAE) and Myomectomy (MYO) in managing symptomatic Uterine Fibroids (UFs) in women who do not want hysterectomy. A meta-analysis was performed on all available studies that evaluated the relative benefits and harms of MYO and UEA for the management of patients suffering from UFs. Outcomes evaluated reintervention, UFs scores for quality of life (QOL) and symptom severity, and other complications. To determine mean differences (MDs) or odds ratios (ORs) with 95% confidence intervals (CIs), a random or fixed-effects model was utilized. A meta-analysis of 13 studies (9 observational and 4 randomized controlled trials) was conducted. The results indicated that UAE had a higher reintervention rate (OR 1.84; 95% CI 1.62-2.10; P < 0.01; I2 = 39%), hysterectomy rate (OR 4.04; 95% CI 3.45-4.72; P < 0.01; I2 = 59%), and symptom-severity score (OR - 4.02; 95% CI 0.82, 7.22; P = 0.01; I2 = 0%) compared to MYO at a four-year follow-up. However, UAE was associated with a lower rate of early complications (OR 0.44; 95% CI 0.20-0.95; P = 0.04; I2 = 25%), and readmission rate (OR 1.16; 95% CI 1.01-1.33; P = 0.04; I2 = 0%) compared to MYO. Furthermore, both procedures had comparable improvement in pregnancy rates and abnormal uterine bleeding. In conclusion, UAE and MYO are effective in treating symptomatic UFs but they have different outcomes. The decision on which procedure to choose should be made based on individual preferences and the physician's expertise.

Causal relationship between gut microbiota and gynecological tumor: a two-sample Mendelian randomization study.

Introduction: Previous research has established associations between alterations in gut microbiota composition and various gynecologic tumors. However, establishing a causal relationship between gut microbiota and these tumors remains necessary. This study employs a two-sample Mendelian randomization (MR) approach to investigate causality, aiming to identify pathogenic bacterial communities potentially involved in gynecologic tumor development. Methods: Data from the MiBioGen consortium's Genome-Wide Association Study (GWAS) on gut microbiota were used as the exposure variable. Four common gynecologic neoplasms, including uterine fibroids (UF), endometrial cancer (EC), ovarian cancer (OC), and cervical cancer (CC), were selected as outcome variables. Single-nucleotide polymorphisms (SNPs) significantly associated with gut microbiota were chosen as instrumental variables (IVs). The inverse variance-weighted (IVW) method was used as the primary MR analysis to assess the causal relationship. External validation An was conducted using an independent. Sensitivity analyses were performed to ensure robustness. Reverse MR analysis was also conducted to assess potential reverse causation. Results: Combining discovery and validation cohorts, we found that higher relative abundance of Lachnospiraceae is associated with lower UF risk (OR: 0.882, 95% CI: 0.793-0.982, P = 0.022). Conversely, higher OC incidence is associated with increased relative abundance of Lachnospiraceae (OR: 1.329, 95% CI: 1.019-1.732, P = 0.036). Sensitivity analyses confirmed these findings' reliability. Reverse MR analysis showed no evidence of reverse causation between UF, OC, and Lachnospiraceae. Discussion: This study establishes a causal relationship between Lachnospiraceae relative abundance and both UF and OC. These findings provide new insights into the potential role of gut microbiota in mechanisms underlying gynecological tumors development.

Navigating Pregnancy With Uterine Fibroids: A Case Study.

Benign uterine tumors, known as leiomyomas or uterine fibroids, can result in severe pain, bleeding, and infertility. They impact a woman's overall well-being, ability to conceive, and the course of her pregnancy. Fibroids are associated with increasing maternal age. When a patient with fibroids is considering pregnancy, ultrasonography and a detailed pelvic examination should be performed to determine the size and location of any fibroids. This case study details a 30-year-old female patient who had fibroids during her pregnancy and responded well to treatment.

A novel scoring system based on magnetic resonance imaging for the prediction of the difficulty of ultrasound-guided high-intensity focused ultrasound ablation for uterine fibroids.

OBJECTIVE: To develop a novel scoring system based on magnetic resonance imaging (MRI) for predicting the difficulty of ultrasound-guided high-intensity focused ultrasound (USgHIFU) ablation for uterine fibroids. MATERIALS AND METHODS: A total of 637 patients with uterine fibroids were enrolled. Sonication time, non-perfused volume ratio (NPVR), and ultrasound energy delivered for ablating 1 mm3 of fibroid tissue volume (E/V) were each classified as three levels and assigned scores from 0 to 2, respectively. Treatment difficulty level was then assessed by adding up the scores of sonication time, NPVR and E/V for each patient. The patients with score lower than 3 were categorized into low difficulty group, with score equal to or greater than 3 were categorized into high difficulty group. The potential predictors for treatment difficulty were compared between the two groups. Multifactorial logistic regression analysis model was created by analyzing the variables. The difficulty score system was developed using the beta coefficients of the logistic model. RESULTS: Signal intensity on T2WI, fibroid location index, largest diameter of fibroids, abdominal wall thickness, homogeneity of the signal of fibroids, and uterine position were independent influencing factors for the difficulty of USgHIFU for uterine fibroids. A prediction equation was obtained: difficulty score = 17 × uterine position (anteverted =0, retroverted =1)+71 × signal intensity (hypointense = 0, isointense/hyperintense = 1) +8 × enhancement (homogenous = 0, heterogeneous = 1)+25×(largest diameter of fibroids-20) +35 × (fibroid location index -0.2) +1×(abdominal wall thickness -5). CONCLUSIONS: This scoring system established based on MRI findings can be used to reliably predict the difficulty level of USgHIFU treatment of uterine fibroids.

Ultrasound-Guided High-Intensity Focused Ultrasound of Uterine Fibroids and Adenomyosis: An 11-Year Experience from a Single Center in Hong Kong.

Introduction: This study evaluated the efficacy and safety of ultrasound-guided high-intensity focused ultrasound (HIFU) in treating symptomatic uterine fibroids and adenomyosis. Methods: HIFU treatments performed in premenopausal women with symptomatic uterine fibroids and adenomyosis were analyzed retrospectively. Lesion volume reduction, change in symptoms of menstrual pain, and quality of life were examined. Major and minor complications, together with re-intervention rates, were evaluated. Results: Eighty-one HIFU treatments were performed in seventy-nine premenopausal women. The follow-up period was up to 95 months. A total of 65 women underwent treatment for uterine fibroids and 14 were treated for adenomyosis. For patients with uterine fibroids, the baseline fibroid volume median was 190.1 cm3 (18.5-1729.4 cm3). Fibroid volume was reduced by 50.1% (-26.2-97.8, p < 0.0001) at 6 months and 66.9% (-33.7-98.3, p < 0.0001) at 12 months after treatment. The modified Uterine Fibroid Symptom and Quality of Life (UFS-QOL) scores had decreased by 43.5% (0-62.5%, p < 0.0001) at 6 months and 50% (0-73%, p < 0.0001) at 12 months after treatment. In the adenomyosis arm, the median baseline uterine volume was 97.7 cm3 (43.7-367.4 m3). Uterine volume was reduced by 19.6% (range: 1.2-42.0, p = 0.28) at 6 months and 41.9% (18.9-69.2, p = 0.04) at 12 months after treatment. UFS-QOL scores were reduced by 38.1% (6-66.7%, p < 0.0001) at 6 months and 40% (0-70%, p < 0.0001) at 12s month after treatment. Fourteen (21.5%) patients with uterine fibroid and five (35.7%) patients with adenomyosis required subsequent interventions. Conclusions: HIFU provides symptomatic relief to most patients with uterine fibroids and adenomyosis. It is a promising uterus-sparing treatment for patients with these conditions.

Risk Factors and Prediction Nomogram of Local Regeneration after Ultrasound-guided Microwave Ablation of Uterine Fibroids.

STUDY OBJECTIVE: To explore the risk factors associated with local regeneration of the treated uterine fibroids (UFs) after microwave ablation (MWA) and to develop a nomogram model for predicting the risk of local regeneration. DESIGN: Retrospective study. SETTING: The Eighth Affiliated Hospital of Sun Yat-Sen University. PATIENTS: Patients with UFs who underwent MWA at our hospital between October 2020 and April 2023 were included. INTERVENTION: MWA was used for the treatment of UFs. MEASUREMENTS AND MAIN RESULTS: A total of 47 patients with 68 fibroids were included into this study. Over a median follow-up of 13 months (interquartile range, 8-22 months), local regeneration occurred in 11 UFs. The clinical and imaging characteristics of these patients were recorded and compared. Risk factors for local regeneration were determined through univariate and multivariate Cox regression analysis. Multivariate analysis revealed that the fertility desires, larger size of UFs (≥95.3 cm3), and hyperenhancement of UFs on contrast-enhanced ultrasound were independent risk factors for local regeneration after MWA. A predictive nomogram was constructed to predict the local regeneration after MWA of UFs. The concordance index (C-index) (C-index, 0.924; internal validation C-index, 0.895) and the 1- and 2-year area under the curve values (0.962, 0.927) all indicated that the nomogram had good predictive performance. Calibration and decision curve analysis curves further confirmed the model's accuracy and clinical utility. CONCLUSION: Fertility desires, larger size of UFs, and hyperenhancement on contrast-enhanced ultrasound were independent predictors of UFs local regeneration after MWA in our study. The nomogram constructed based on the abovementioned independent risk factors may help predict which UFs will develop local regeneration after MWA.

The role of VEGF and TGF-ß blood levels for fibroid shrinkage, menorrhagia score, and quality of life improvement after uterine artery embolization for uterine fibroids: a study protocol.

Uterine leiomyoma is a common condition affecting women that occurs in more than 70% of females. Women with leiomyomas overall have lower quality of life and deficiency in many specific spheres of life including work-related productivity, sexuality, relationships, social-emotional health, and physical well-being that might be present even in pre-and extended throughout early postmenopausal life. Choices for symptomatic fibroid management include medical, interventional radiology procedures, surgical, and expectant management. The uterine artery embolization (UAE) procedure has gained justified popularity for myoma management. Growth factors, vascular endothelial growth factor (VEGF) and tumor growth factor ß (TGF-ß), hold an important role in leiomyoma progression. However, blood levels of VEGF and TGF-ß in patients before and after UAE are not fully investigated and the possible relationship with myoma shrinkage has not been evaluated. Therefore, this study aims to assess menorrhagia score and quality of life improvement after UAE for uterine fibroids and compare blood levels of VEGF and TGF-ß in patients with uterine leiomyoma before and after UAE. This cross-sectional study will be performed at the University Medical Center, Astana, Kazakhstan. Women undergoing the UAE procedure for uterine leiomyoma will be involved in the study following the precisely defined inclusion/exclusion criteria. Uterine leiomyoma nodules' structural changes after UAE will be assessed along with the blood levels of growth factors (VEGF and TGF-ß), menorrhagia score, and quality of life. An important outcome of this project will be an investigation of the blood levels of growth factors (VEGF and TGF-ß) before and after the procedure and their association with leiomyoma shrinkage in correlation with the menorrhagia score and quality of life alterations among patients undergoing UAE.

Long-term obstetric, perinatal, and surgical complications in singleton pregnancies following previous cesarean myomectomy: a retrospective multicentric study.

Objectives: The safety of cesarean myomectomy has been proven by previous studies. Our study aimed to reveal the long-term perinatal, obstetric, and surgical outcomes of cesarean myomectomy (CM) by comparing different CM techniques. Material and methods: This retrospective multicentric case-control study involved 7 hospitals and included 226 singleton pregnancies that underwent repeated cesarean section (CS) between 2015 and 2020. Among these pregnancies, 113 of 226 cases had CM (Group A), and 113 had only CS (Group B). Of the 113 cases in which CM was performed, 58 underwent endometrial myomectomy (EM) (Subgroup A1) and 55 underwent serosal myomectomy (SM) (Subgroup A2). The groups were compared in terms of obstetric, perinatal, and surgical outcomes, and fibroid recurrence, myomectomy scar healing rate, and adhesion formation were noted. Results: There was no significant difference between the groups in terms of maternal age, body mass index, gravidity, parity, and fibroid diameter in previous CS (p > 0.05). In the perinatal and obstetric evaluation of the groups, there was no significant difference between the groups in terms of neonatal weight, Apgar score, fetal growth restriction, preterm premature rupture of membranes, preterm delivery, hypertension in pregnancy, and diabetes mellitus (p > 0.05). The fibroid recurrence rate was 28.3%, and the myomectomy scar good healing rate was 99.1%. There was no difference between the groups in terms of CS duration, preoperative and postoperative hemoglobin levels, perioperative blood transfusion rates, febrile morbidity, and prolonged hospitalization (p > 0.05). In terms of adhesion formation, although the adhesion rate of the SM group was higher than that of the EM group, no statistically significant difference was detected between the groups. Conclusion: This study showed that in pregnancies following CM, obstetrical, perinatal, and surgical outcomes were unaffected. Obstetricians can safely use CM, either the trans-endometrial or serosal technique, as it is a safe and effective method with long-term results.

Uterine fibroids: current research on novel drug targets and innovative therapeutic strategies.

INTRODUCTION: Uterine fibroids, the most common nonmalignant tumors affecting the female genital tract, are a significant medical challenge. This article focuses on the most recent studies that attempted to identify novel non-hormonal therapeutic targets and strategies in UF therapy. AREAS COVERED: This review covers the analysis of the pharmacological and biological mechanisms of the action of natural substances and the role of the microbiome in reference to UFs. This study aimed to determine the potential role of these compounds in UF prevention and therapy. EXPERT OPINION: While there are numerous approaches for treating UFs, available drug therapies for disease control have not been optimized yet. This review highlights the biological potential of vitamin D, EGCG and other natural compounds, as well as the microbiome, as promising alternatives in UF management and prevention. Although these substances have been quite well analyzed in this area, we still recommend conducting further studies, particularly randomized ones, in the field of therapy with these compounds or probiotics. Alternatively, as the quality of data continues to improve, we propose the consideration of their integration into clinical practice, in alignment with the patient's preferences and consent.

Thinking in context: Fibroids-to-uterine volume ratio in pre-surgical fertility evaluation for intramural fibroids.

OBJECTIVE: To explore the utility of the total fibroids-to-uterine volume (FTUV) ratio as a simple, preoperative tool to assist in counseling patients seeking pregnancy who are undergoing myomectomy for intramural (IM) fibroids. STUDY DESIGN: This is an historical cohort study on reproductive-aged patients seeking pregnancy who underwent laparotomic myomectomy for intramural fibroids from January 2017 to December 2021. Only G3 to G5 fibroids, according to the 2011 International Federation of Gynecology and Obstetrics (FIGO) classification, were included. Pre-operative transvaginal ultrasound (TVUS) was performed to measure the volume of intramural myomas (diameter1*diameter2*diameter3*0.52) and to calculate their total volume. The total fibroids-to-uterine volume (FTUV) ratio was calculated as the proportion of the uterine volume occupied by the sum of IM fibroids volumes. RESULTS: A total of 166 women with pre-surgical TVUS evaluation of IM fibroids were included, with a mean age of 36.22 ± 5.15 years. The FTUV ratio was identified as a positive predictor of clinical pregnancy after surgery (adjOR, 1.04; 95 % CI, 1.02-1.06; p = 0.0001), whereas age showed a negative association (adjOR, 0.90; 95 % CI, 0.83-0.98; p = 0.012). Endometrial cavity distortion prior to surgery was also positively associated with pregnancy post-surgery (adjOR, 3.50; 95 % CI, 1.51-8.08; p = 0.003). Consistent results were found for live births, with the FTUV ratio being a significant positive predictor of live birth after surgery (adjOR, 1.03; 95 % CI, 1.01-1.05; p = 0.001) and age showing a negative association (adjOR, 0.88; 95 % CI, 0.80-0.96; p = 0.004). Parity prior to surgery also positively impacted live birth post-surgery (adjOR, 2.65; 95 % CI, 1.30-5.40; p = 0.007). An FTUV ratio threshold of 53.39 % accurately predicted clinical pregnancy in 68.46 % of cases (sensitivity of 71.70 % and specificity of 66.67 %). For live births, a higher FTUV ratio threshold of 59.21 % predicted outcomes accurately in 69.13 % of cases (sensitivity of 65.85 % and specificity of 70.37 %). CONCLUSION: The use of the FTUV ratio in pre-operative ultrasound evaluation of IM fibroids may improve counseling for patients desiring to conceive after myomectomy. By providing a personalized assessment of the amount of myometrial volume occupied by fibroids, the FTUV ratio can help predict fertility outcomes after surgery, enabling better-informed decisions and treatment planning.

Comprehensive Review of Uterine Leiomyosarcoma: Pathogenesis, Diagnosis, Prognosis, and Targeted Therapy.

Uterine leiomyosarcoma (uLMS) is the most common subtype of uterine sarcomas. They have a poor prognosis with high rates of recurrence and metastasis. The five-year survival for uLMS patients is between 25 and 76%, with survival rates approaching 10-15% for patients with metastatic disease at the initial diagnosis. Accumulating evidence suggests that several biological pathways are involved in uLMS pathogenesis. Notably, drugs that block abnormal functions of these pathways remarkably improve survival in uLMS patients. However, due to chemotherapy resistance, there remains a need for novel drugs that can target these pathways effectively. In this review article, we provide an overview of the recent progress in ascertaining the biological functions and regulatory mechanisms in uLMS from the perspective of aberrant biological pathways, including DNA repair, immune checkpoint blockade, protein kinase and intracellular signaling pathways, and the hedgehog pathway. We review the emerging role of epigenetics and epitranscriptome in the pathogenesis of uLMS. In addition, we discuss serum markers, artificial intelligence (AI) combined with machine learning, shear wave elastography, current management and medical treatment options, and ongoing clinical trials for patients with uLMS. Comprehensive, integrated, and deeper insights into the pathobiology and underlying molecular mechanisms of uLMS will help develop novel strategies to treat patients with this aggressive tumor.

Common Beverage Consumption and Benign Gynecological Conditions.

The purpose of this article is to review the effects of four commonly consumed beverage types-sugar-sweetened beverages (SSBs), caffeinated beverages, green tea, and alcohol-on five common benign gynecological conditions: uterine fibroids, endometriosis, polycystic ovary syndrome (PCOS), anovulatory infertility, and primary dysmenorrhea (PD). Here we outline a plethora of research, highlighting studies that demonstrate possible associations between beverage intake and increased risk of certain gynecological conditions-such as SSBs and dysmenorrhea-as well as studies that demonstrate a possible protective effect of beverage against risk of gynecological condition-such as green tea and uterine fibroids. This review aims to help inform the diet choices of those with the aforementioned conditions and give those with uteruses autonomy over their lifestyle decisions.

Hypoxia in uterine fibroids: role in pathobiology and therapeutic opportunities.

Uterine fibroids are the most common tumors in females affecting up to 70% of women world-wide, yet targeted therapeutic options are limited. Oxidative stress has recently surfaced as a key driver of fibroid pathogenesis and provides insights into hypoxia-induced cell transformation, extracellular matrix pathophysiology, hypoxic cell signaling cascades, and uterine biology. Hypoxia drives fibroid tumorigenesis through (1) promoting myometrial stem cell proliferation, (2) causing DNA damage propelling transformation of stem cells to tumor initiating cells, and (3) driving excess extracellular matrix (ECM) production. Common fibroid-associated DNA mutations include MED12 mutations, HMGA2 overexpression, and Fumarate hydratase loss of function. Evidence suggests an interaction between hypoxia signaling and these mutations. Fibroid development and growth are promoted by hypoxia-triggered cell signaling via various pathways including HIF-1, TGFß, and Wnt/ß-catenin. Fibroid-associated hypoxia persists due to antioxidant imbalance, ECM accumulation, and growth beyond adequate vascular supply. Current clinically available fibroid treatments do not take advantage of hypoxia-targeting therapies. Growing pre-clinical and clinical studies identify ROS inhibitors, anti-HIF-1 agents, Wnt/ß-catenin inhibition, and TGFß cascade inhibitors as agents that may reduce fibroid development and growth through targeting hypoxia.

Assessing the impact of hormonal contraceptive use on menstrual health among women of reproductive age - a systematic review.

BACKGROUND: Contraceptive methods are well-established in their ability to prevent pregnancy and increase individual agency in childbearing. Evidence suggests that contraceptives can also be used to treat adverse conditions associated with menstruation, including abnormal and prolonged uterine bleeding, heavy menstrual bleeding, painful menstruation, endometriosis, uterine fibroids, and premenstrual dysphoric disorders.This review investigates the effects of contraceptive techniques such as contraceptive pills, and long-acting reversible contraceptives (e.g. intrauterine devices, implants) on menstrual morbidity. METHODS: Over ten databases with no geographical boundaries were searched from inception until October 2023. Study designs were one of the following types to be included: parallel or cluster randomised controlled trials, controlled clinical trials, controlled before and after studies, interrupted time series studies, cohort or longitudinal analyses, regression discontinuity designs, and case-control studies. Ten team members screened the papers in pairs with a Kappa score of more than 7, and Covidence was used. Conflicts were resolved by discussion, and the full papers were divided among the reviewers to extract the data from eligible studies. RESULTS: Hormonal contraceptives are considered a well-tolerated, non-invasive, and clinically effective treatment for abnormal and prolonged uterine bleeding, heavy menstrual bleeding, painful menstruation, endometriosis, uterine fibroids, and premenstrual dysphoric disorders. Our studies investigating quality of life or well-being in women with heavy menstrual bleeding, endometriosis, or uterine fibroids have found improvements in all dimensions assessed. CONCLUSIONS: Hormonal contraceptives significantly reduce pain, symptom severity, and abnormal bleeding patterns associated with women who suffer from heavy menstrual bleeding, endometriosis, and uterine fibroids.

Hormonal contraceptives significantly reduce pain, symptom severity, and abnormal bleeding patterns associated with women who suffer from heavy menstrual bleeding, endometriosis, and uterine fibroids. Findings can inform clinical practice and policy decisions to ensure that women have access to safe and effective contraceptive options that promote both reproductive and non-reproductive health.
