Article Citation - WoS: 1Citation - Scopus: 1Detection of Sexually Transmitted Infection Agents in Pregnant Women Using Multiplex Polymerase Chain Reaction Method(BMC, 2025) Bakir, Ayfer; Cendek, Busra Demir; Usluca, Selma; Aral, Murat; Korkut, Gizem; Morkoc, Mehmet; Keskin, Huseyin LeventBackgroundSexually transmitted infections (STIs) are a significant public health concern that can lead to serious outcomes such as infertility, pregnancy complications, and neonatal infections. This study aimed to evaluate the prevalence of STI and their associated risk factors in symptomatic and asymptomatic pregnant women.MethodsBetween July and October 2024, a total of 300 pregnant women in their third trimester, including 113 symptomatic and 187 asymptomatic individuals aged 18 to 45 years, who sought antenatal care at the Gynecology and Obstetrics Clinic of Ankara Etlik City Hospital, were included in the study. The detection of STIs agents in vaginal swab samples was performed using multiplex polymerase chain reaction in the Molecular Diagnosis Laboratory of the Department of Microbiology.ResultsThe overall prevalence of STIs was 34.3% (103/300), with single and multiple infections accounting for 28.3% and 6.0% of cases, respectively. The most frequently detected pathogens were Ureaplasma parvum/urealiticum (29.0%), Mycoplasma hominis (4.6%), and Chlamydia trachomatis (2.3%). Co-infections were commonly observed between Ureaplasma parvum/urealiticum and Mycoplasma hominis. No significant difference in STI prevalence was observed between the symptomatic (35.4%) and asymptomatic (33.7%) groups. Co-infection with non-STI bacterial agents, such as Gardnerella vaginalis and Streptococcus agalactiae, increased the risk of STIs by 1.96 times (p = 0.006).ConclusionsThis study revealed that STIs occur at similar rates among symptomatic and asymptomatic pregnant women. This finding highlights the critical importance of detecting asymptomatic cases to prevent the spread of silent infections and to safeguard maternal and neonatal health. Ureaplasma parvum/urealiticum were identified as the most common pathogens. Given that co-infections with non-STI bacterial agents significantly increase the risk of STIs, multiplex PCR-based multicenter and prospective studies are essential to refine screening strategies for pregnant women.Article Citation - WoS: 1Citation - Scopus: 1A Comparative Analysis of Progestin-Primed Ovarian Stimulation Versus GnRH Antagonists Protocols Pertaining To Stimulation Parameters and Embryological Outcomes in Patients With Endometrioma(Frontiers Media SA, 2025) Boynukalin, Fazilet Kübra; Tohma, Yusuf Aytaç; Gültomruk, Meral; Yarkiner, Zalihe; Akkaya, Ceren Melisa; Özkavukçu, Sinan; Bozdaǧ, GürkanResearch question: Do embryo parameters and live birth rates differ between patients with endometrioma undergoing a freeze-all strategy using either GnRH antagonists or progestin-primed ovarian stimulation (PPOS)? Design: This retrospective cohort study was conducted at Bahceci Health Group from January 2021 to January 2023. Inclusion criteria were females aged 20–40 with confirmed endometriosis, using either GnRH antagonists or PPOS ovarian stimulation, and opting for freezing all embryos without fresh embryo transfer (ET). A total of 543 patients were analyzed, with the primary outcome being usable embryos at cleavage stage and secondary outcomes including distribution of embryo quality, clinical pregnancy, and live birth rate. Results: For the GnRH antagonist arm, the median (25th-75th percentiles) total gonadotropin dose required during stimulation was significantly higher (2725 [2100–3587.5] vs. 2400 [2050–3075] IU, p = 0.001) and duration was longer (11 [10–12] vs. 10 [9–11] days, p = 0.01), although number of mature oocytes and maturation and fertilization rates were similar in both arms. However, the linear regression analysis revealed that the number of usable day-three embryos was higher with the PPOS protocol than with the GnRH antagonist protocol (OR: 0.890, CI 95%: 0.226 – 1.554, p= 0.009). Particularly in patients that had undergone FET, the respective live birth rates were 50.0% and 54.6% in GnRH antagonist and PPOS arms, respectively, without any statistical significance (p= 0.365). Conclusion: In patients with endometrioma, the PPOS protocol over GnRH antagonists might potentially enhance the quantity of usable cleavage-stage embryos while showing no significant impact on the number of collected oocytes. © 2025 Elsevier B.V., All rights reserved.
