Background: Type II ovarian cancer (OC) is generally diagnosed at an advanced stage, translating into a poor survival rate. Current screening methods for OC have failed to demonstrate a reduction in mortality. The uterine lavage technique has been used to detect tumor-specific mutations from cells presumably shed from high-grade serous ovarian cancer (HGSOC). We aimed to pilot whether the detection of mutation in uterine cavity lavage can be used as a diagnostic method for HGSOC using an expanded gene panel.
Methods: In this study 90, uterine lavage and 46 paired biopsy samples were analyzed using next-generation sequencing (NGS) targeting as well as five additional OC-related genes: , , , , and .
Results: Uterine lavage was successfully applied to all patients, and 56 mutations were detected overall. mutations were detected in 27% (10/37) of cases of type HGSOC; and mutations were also frequent in this group (46%; 17/37). Overall concordance between tissue and liquid biopsy samples was 65.2%.
Conclusion: Uterine lavage mutations in combination with other biomarkers could be a useful tool for the detection of lowly invasive HGSOC.

Metabolomic and microbiota profiles in cervicovaginal lavage fluid of women with high-risk human papillomavirus infection.

The presence of high-risk human papillomavirus (HR-HPV) contributes to the development of cervical lesions and cervical cancer. Recent studies suggest that an imbalance in the cervicovaginal microbiota might be a factor in the persistence of HR-HPV infections. In this study, we collected 156 cervicovaginal fluid (CVF) of women with HR-HPV infection, which were divided into three groups (negative for intraepithelial lesions = 78, low/high-grade squamous intraepithelial lesions = 52/26).

Background: Ectopic pregnancy, occurring outside the uterine cavity, poses a significant health risk, with Fallopian tube involvement being predominant. Recurrent ectopic pregnancy, particularly in the ipsilateral remnant of a previously removed tube, is a rare and poorly understood phenomenon. Here, we present a case of recurrent ectopic pregnancy occurring in the distal remnant of the right fallopian tube following ipsilateral incomplete salpingectomy in a 22-year-old woman.

Article Synopsis
- - Endometritis is a major factor causing subfertility in mares, and studying the uterine fluid's protein composition can help improve understanding and treatment of the condition.
- - The research involved analyzing the protein profiles of uterine fluid from healthy mares and those with different types of endometritis, revealing 549 detectable proteins and focusing on 279 common to all groups.
- - Significant differences were found in protein abundance between healthy mares and those with infections or post-breeding endometritis, leading to insights on potential biomarkers for diagnosis and treatment of the disease.
Uterus histomorphometry of alpacas () in induced luteal phase, with GnRH or copulation.

Information and Education Center for the Prevention of Drug Abuse - CEDRO, Lima, Peru.
Article Synopsis
- Alpacas exhibit unique reproductive traits, including induced ovulation and differences in uterine horn gestation rates, but challenges like low fertility and high embryonic mortality persist, prompting further study of the uterine wall changes during the luteal phase.
- The research aimed to investigate histological changes in the uterine wall of alpacas, analyzing samples from both left and right uterine horns after inducing ovulation via GnRH or natural mating.
- Results indicated that copulation (G2) led to thicker uterine layers and larger gland areas in the left horn, suggesting better developmental conditions during the luteal phase, and highlighting new insights into alpaca reproductive physiology.

Endometrial cancer (EC) rates are continuing to rise and it remains the most common gynecologic cancer in the US. Existing diagnostic methods are invasive and can cause pain and anxiety. Hence, there is a need for less invasive diagnostics for early EC detection.
