BACKGROUND: Leukemia patients undergoing cryopreserved ovarian tissue transplantation (OTT) may carry a high risk of disease induction. Measurable residual disease (MRD) in bone marrow is linked to an elevated risk of relapse. It is controversial whether leukemia patients must be allowed to achieve measurable residual disease negative (MRD-negative) status instead of measurable residual disease positive (MRD-positive) status before ovarian tissue cryopreservation (OTC). OBJECTIVE: To explore the safety and efficacy of OTT in acute leukemia patients with different MRD status by using xenotransplantation...

As a broad-spectrum and efficient insecticide, beta-Cypermethrin (β-CYP) poses a health risk to pregnancy. It matters the mechanisms of maternal exposure to β-CYP for impacting reproductive health. The placenta, a transient organ pivotal for maternal-fetal communication during pregnancy, plays a crucial role in embryonic development. The effect of β-CYP exposure on the placenta and its underlying molecular mechanisms remain obscure. The objective of this study was to investigate the effect of β-CYP exposure on placental development and the function of trophoblast, as well as the underlying mechanisms through CD-1 mouse model (1, 10, 20mg/kg...

Exposure to glyphosate-based herbicides (GBH) and consumption of cafeteria (CAF) diet, which are widespread in Western society, seem to be associated with endometrial hyperplasia (EH). Here, we aimed to evaluate the effects of a subchronic low dose of a GBH added to CAF diet on the rat uterus. Female Wistar rats were fed from postnatal day (PND)21 until PND240 with chow (Control) or CAF diet. Since PND140, rats also received GBH (2 mg of glyphosate/kg/day) or water through food, yielding four experimental groups: Control, CAF, GBH and CAF+GBH...

INTRODUCTION: Uterine arteriovenous malformations (AVMs) are a rare cause of obstetrical hemorrhage. It can be congenital due to a defect during embryogenesis or acquired. Uterine AVMs can cause life threatening postpartum hemorrhage, and is most frequently misdiagnosed. This case highlights the diagnostic challenges posed by uterine arteriovenous malformation, a rare vascular anomaly that poses significant challenges in diagnosis and management. CASE PRESENTATION: This case report details the clinical presentation, diagnostic challenges, and treatment approach for a 39-year-old woman...

AIM: Our aim is to investigate the effect of uterine lower segment involvement on prognosis of early-stage endometrial cancer cases diagnosed and treated in our clinic. MATERIALS AND METHODS: The file records of 316 cases reviewed retrospectively.Only stage I (a and b, n=209) cases were investigated, because they were more homogeneous group. RESULTS: The lymphovascular invasion rate was found to be higher in patients with stage Ia and uterine lower segment involvement (p < 0...

Introduction: Leiomyomas are associated with lower urinary tract symptoms (LUTS), but more specific characterization of their impact on LUTS is needed. Methods: This is a retrospective cohort study of 202 participants (101 per group) who underwent hysterectomy for leiomyomas versus abnormal uterine bleeding nonclassified (AUB-N) from July 2015 to May 2019. Baseline demographics, leiomyoma characteristics, and presence of baseline LUTS were collected. The main objective was to compare the prevalence of LUTS between these two groups...

BACKGROUND: In Australia, gynaecologists continue to assess and investigate abnormal uterine bleeding with inpatient hysteroscopy despite evidence validating outpatient hysteroscopy services. AIM: This retrospective cohort study assessed the safety, success and acceptability of office hysteroscopy in a gynae-oncology rapid-access clinic over six years in Sydney, Australia, and included all women without an age or body mass index (BMI) cut-off using a 'see and treat' concept...

INTRODUCTION: Prior to pregnancy, hormonal changes lead to cellular adaptations in the endometrium allowing for embryo implantation. Critical for successful pregnancy establishment, innate immune cells constitute a significant proportion of uterine cells prior to arrival of the embryo and throughout the first trimester in humans and animal models. Abnormal uterine immune cell function during implantation is believed to play a role in multiple adverse pregnancy outcomes. Current work in humans has focused on uterine immune cells present after pregnancy establishment, and limited in vitro models exist to explore unique functions of these cells...

INTRODUCTION: Women presenting with abnormal uterine bleeding needs careful and thorough assessment including ultrasound examination of endometrium and histopathological assessment of the endometrial tissues. The objective of this cross-sectional study was to determine the rate and the factors associated with inadequate endometrial tissues after endometrial sampling using MedGyn® pipette among Bhutanese women at the colposcopy clinic, Jigme Dorji Wangchuck National Referral Hospital (JDWNRH), Bhutan...

UNLABELLED: Uterine natural killer cells (uNKs) are a tissue resident lymphocyte population that are critical for pregnancy success. Although mouse models have demonstrated that NK deficiency results in abnormal placentation and poor pregnancy outcomes, the generalizability of this knowledge to humans remains unclear. Here we identify uterus transplant (UTx) recipients as a human population with reduced endometrial NK cells and altered pregnancy phenotypes. We further show that the NK reduction in UTx is due to impaired transcriptional programming of NK tissue residency due to blockade of the transcription factor nuclear factor of activated T cells (NFAT)...

STUDY OBJECTIVE: To define objective and readily applied diagnostic criteria for Y-shaped uteri using three-dimensional transvaginal ultrasound (3D-TVUS) volume recordings. DESIGN: A retrospective case-control diagnostic measurements study. SETTING: A tertiary university hospital's reproductive health and research centre. PATIENTS: 213 patients who presented with infertility between January 2020 and December 2022. INTERVENTION: Two blinded physicians re-evaluated the 3D-TVUS images of all patients for the presence of a uterine abnormality...

BACKGROUND: Persistent pregnancies of unknown location (PUL) are defined by abnormally trending serum human chorionic gonadotropin with nondiagnostic ultrasound. There is no consensus on optimal management. OBJECTIVE: This study was designed to assess the cost-effectiveness between three primary management strategies for persistent pregnancies of unknown location: (1) expectant management, (2) empirical two-dose methotrexate, (3) uterine evacuation followed by methotrexate, if indicated...

BACKGROUND: As the cesarean delivery rate continues to rise globally, the treatment of previous cesarean scar defects (PCSD) remains challenging. This study aimed to analyze the variables that may influence the clinical cure rate of patients with PCSD-related abnormal uterine bleeding (AUB) as determined by preoperative magnetic resonance imaging (MRI) following hysteroscopic therapy. METHODS: Women who underwent hysteroscopic surgery for PCSD-related AUB at the Gynecology Department of Third Xiangya Hospital of Central South University from 2018 to 2022 were recruited to this retrospective cohort investigation...

BACKGROUND: Adults in Saudi Arabia are more likely to be obese, which has negative effects on reproductive health, especially for women. While bariatric surgery (BS) provides a sustainable approach, little is known about how it affects menstrual health and requires a study among the Saudi demographic. METHODS: The current investigation is a cross-sectional study conducted in Saudi Arabia. Data were collected using an online questionnaire to assess the impact of BS on menstrual abnormalities in women...

A uterine scar defect, or isthmocele, is one of the known complications of cesarean delivery. It can cause obstetric as well as gynecological problems. Diagnosis can be suspected based on complaints such as abnormal uterine bleeding, pelvic pain, dysmenorrhea, and subfertility. It can be investigated by transvaginal ultrasound and MRI hysteroscopy. A hysteroscopy gives a confirmatory diagnosis. Isthmoplasty may be offered to avoid future obstetric complications and treat symptoms. In the present case report, a patient with prolonged postmenstrual dark-colored spotting underwent isthmocele repair by a procedure that could be unique, which is transvaginal isthmocele repair with temporary occlusion of uterine vessels...

Uterine leiomyomas are rare in the paediatric population. This report describes a rare case of a submucous leiomyoma in an adolescent girl. The patient presented with a history of abnormal and painful period which was refractory to medical treatment. Sonographic findings revealed a uterine mass that protruded through the cervix until the upper third of the vagina. A hysteroscopic resection was performed, and a pathological examination confirmed a leiomyoma. 12 months after surgery, there were no signs of recurrence...

BACKGROUND/AIM: Uterine leiomyosarcoma (uLMS) is a rare, highly malignant, and invasive cancer, with early metastasis. Mismatch repair (MMR) proteins and matrix metalloproteinases (MMPs) are associated with the occurrence, proliferation, and invasion of most malignant cancers; however, their abnormal expression in uLMS remains poorly clarified. PATIENTS AND METHODS: Immunohistochemistry was performed to assess MMR protein and MMP2/9 expression as well as Ki67 marker proliferation in benign and malignant uterine smooth muscle tumors...
