Background: Endometrial stromal sarcomas (ESS) are rare uterine mesenchymal tumors that histologically resemble endometrial stroma of functioning endometrium. The key characteristic of those tumors is the difficulty to diagnose preoperatively that leads to high rate of misdiagnosis. The aim of this case report is to present an extremely rare mutation of these already rare tumors and urge for more personalized therapies in the future.

Poor ovarian response (POR) remains a significant challenge in the field of assisted reproductive technology (ART), as the quantity and quality of oocytes retrieved directly influence embryo implantation, clinical pregnancy, and live birth rates. Metabolomics has become a valuable tool for elucidating the molecular mechanisms underlying diminished ovarian reserve (DOR) and POR. This review aims to synthesize findings from metabolomic studies examining metabolite expression patterns in serum and follicular fluid samples from women with POR.

Background/objectives: Preterm labor is a leading cause of neonatal morbidity and mortality worldwide. Previous research has indicated that an inflammatory response or microbial invasion of the amniotic cavity is a pathological condition linked to preterm birth; hence, inflammatory markers such as metalloproteinase-9 (MMP-9), interleukin-6 (IL-6), and interleukin-8 (IL-8) have been utilized to predict preterm delivery. The identification of reliable biomarkers for early prediction is critical for improving maternal, fetal, and neonatal outcomes.

Chronic inflammation is increasingly recognized as a critical factor in female reproductive health; influencing natural conception and the outcomes of assisted reproductive technologies such as in vitro fertilization (IVF). An essential component of innate immunity, the NLR family pyrin domain-containing 3 (NLRP3) inflammasome is one of the major mediators of inflammatory responses, and its activation is closely linked to oxidative stress. This interaction contributes to a decline in oocyte quality, reduced fertilization potential, and impaired embryo development.

Bisphenols, particularly bisphenol A (BPA), are among the most thoroughly investigated endocrine disrupting chemicals (EDCs). BPA was the first synthetic estrogen to be identified, exerting its estrogenic effects through interaction with human estrogen receptors (ERs). The aim of the present narrative review is to summarize the most recent literature regarding the adverse effects of bisphenols on female fertility and pregnancy outcomes.

Plasma cell-free DNA (cfDNA) analysis to track estrogen receptor 1 (ESR1) mutations is highly beneficial for the identification of tumor molecular dynamics and the improvement of personalized treatments for patients with metastatic breast cancer (MBC). Plasma-cfDNA is, up to now, the most frequent liquid biopsy analyte used to evaluate ESR1 mutational status. Circulating tumor cell (CTC) enumeration and molecular characterization analysis provides important clinical information in patients with MBC.

Retrotransposable elements are implicated in genome rearrangements and gene expression alterations that result in various human disorders. In the current study, we sought to investigate the potential effects of long interspersed elements-1 (LINE-1) overexpression on the integrity and methylation of DNA and on the expression of three major pluripotency factors (OCT4, SOX2, NANOG) during the preimplantation stages of human embryo development. Human MI oocytes were matured in vitro to MII and transfected through intracytoplasmic sperm injection (ICSI) either with an EGFP vector carrying a cloned active human LINE-1 retroelement or with the same EGFP vector without insert as control.

: Caesarean scar pregnancy (CSP) is a rare form of ectopic pregnancy in which the early pregnancy implants at the site of the uterine scar. Methotrexate (MTX) in lower doses can be used to treat CSPs. However, MTX administration is associated with a spectrum of side effects that include hematological toxicities.

The purpose of this prospective case-control study is to investigate the correlation of the miR-143 gene rs353292 polymorphism in Caucasian women with recurrent pregnancy loss (RPL) compared to a matched control group with at least one live birth and without pregnancy losses. In total, 110 women with recurrent pregnancy losses and 95 control women were recruited. Peripheral blood was collected from all women, and the isolation of DNA was performed with Monarch Genomic DNA Purification.

Background/objectives: Embryo implantation is a highly complex process that requires the precise regulation of numerous molecules to be orchestrated successfully. Micro RNAs (miRNAs) are small non-coding RNAs that regulate gene expression and play a crucial role in the regulation of embryo implantation. This article aims to summarize the key findings of the literature regarding the role of miRNAs in human embryo implantation, emphasizing their involvement in critical stages such as decidualization, endometrial receptivity and trophoblast adhesion.

Background: Cabazitaxel is an effective treatment in metastatic castration-resistant prostate cancer (mCRPC) patients previously exposed to docetaxel and novel hormonal treatments. Understanding the molecular biology of mCRPC disease and taking into account the several approved treatment options, biomarkers are needed to guide decision making including cabazitaxel treatment.
Methods: Cababone was a phase II translational study that attempted to identify predictors of cabazitaxel efficacy.

Antioxidants have a well-established effect on general health and are essential in preventing oxidative damage to cells by scavenging free radicals. Free radicals are thought to be neutralized by these substances, which include polyphenols, β-carotene, and vitamins C and E, reducing cellular damage. On the other hand, recent data indicates that consuming excessive amounts of antioxidants may have side effects.

We present a 39-centimeter thecoma with ascites and elevated Ca-125 values which is compatible with an atypical/incomplete Meigs' syndrome. Giant ovarian masses with elevated Ca-125 values and ascites are an alarming combination, although Gynecologists should be aware that there are also benign entities that mimic advanced stage ovarian cancer.

Male factors may be present in up to 50-70% of infertile couples and the prevalence of male infertility accounts for 20-30% of infertility cases. Understanding the mechanisms and causes behind male infertility remains a challenge, but new diagnostic tools such as DNA fragmentation might aid in cases where the routine semen analysis is insufficient. DNA fragmentation, which refers to damages or breaks of the genetic material of the spermatozoa, is considered one of the main causes of male infertility due to impaired functional capability of sperm.

Human papillomavirus (HPV) infections are significantly associated with multiple adverse reproductive outcomes such as miscarriages. Pregnant women are more susceptible to an HPV infection and its prevalence increases as pregnancy progresses. In this present review, we summarize the existing evidence indicating the potential impact of an HPV infection on the occurrence of recurrent pregnancy loss (RPL).

: Infertility constitutes a significant challenge for couples around the world. Ovarian dysfunction, a major cause of infertility, can manifest with anovulatory cycles, elevated follicle-stimulating hormone levels, and diminished ovarian reserve markers such as anti-Müllerian hormone (AMH) levels or the Antral Follicle Count (AFC). Blood-derived therapies including platelet-rich plasma (PRP) have been used in fertility treatments in women with low ovarian reserve or premature ovarian insufficiency.

Introduction: Real-world data on management of metastatic castration resistant prostate cancer (mCRPC) with novel therapies is sparse. The aim of this study was to capture real-world management strategies in patients with mCRPC who initiated first line (1L) systemic therapy with chemotherapy or novel hormonal agents (NHAs) in Greece and describe the therapeutic sequencing strategy among patients who advanced to 2L and 3L treatment.
Patients And Methods: In this noninterventional, multicentre, retrospective study (PROSPECT), a medical chart review of 149 patients with mCRPC who initiated 1L systemic therapy with chemotherapy or NHAs in 7 major anticancer hospital clinics, from public, academic, and private sectors in Greece was conducted.
