Introduction: The Coronavirus Disease-2019 pandemic is considered the most catastrophic disease of the last decades, with evolving knowledge and improved management over time. Pregnant women are known to be particularly vulnerable, and COVID-19 has been shown to damage the endothelium due to its proinflammatory nature. Aim: To determine the occurrence of oligohydramnios in pregnant women who tested positive for COVID-19. Materials and Methods: A retrospective observational study was conducted at the Department of Obstetrics and Gynaecology, Koru Health Groups, Ankara, Çankaya, Turkey from January 2023 to June 2023. The study included a total of 459 women who were followed during pregnancy and delivered in the same hospital between April 2020 and October 2022. The patients were divided into two groups: COVID-19 positive group (n=101) and negative group (n=358). Various parameters such as age, parity, gestational week at birth, Body Mass Index (BMI), 1st and 5th-minute Appearance, Pulse, Grimace, Activity and Respiration (APGAR) scores, weight of the newborn, Amniotic Fluid Index (AFI), and the risk of developing oligohydramnios were assessed between the positive and negative groups. Parametric variables were analysed using independent t-tests and non parametric ones using Mann-Whitney U tests. Chi-square test was used to compare categorical variables. A p-value of

Abstract Objective The aim of the present study is to compare the effectiveness of Arabin pessary and McDonald cervical cerclage on preterm delivery. Methods We conducted a retrospective analysis of data from patients who underwent either Arabin pessary or McDonald cerclage between January 1, 2019, and January 1, 2023. A total of 174 patients were included in the study, with 31 undergoing Arabin pessary and 143 receiving cervical cerclage using the McDonald technique in singleton pregnant women with cervical insufficiency, which applied between 14 and 22 gestational weeks. We included singleton pregnant women with normal morphology, and with normal combined test. The primary outcome was the impact of each method on preterm delivery (< 34 gestational weeks). Results The weeks of cervical cerclage or pessary application were compatible with each other (p< 0.680). The pessary group had a statistically significant longer time to delivery compared with the Cerclage group (cerclage group mean 30.8 c 7.1 standard deviation [SD] versus pessary group mean 35.1 ± 4.4 SD; p< 0.002). A statistically significant difference was found between the pessary and cerclage groups in terms of delivery at < 34 weeks (p= 0.002). In patients with cervical length between 25 and 15mm and < 15mm, no significant difference was found between the pessary and cerclage groups in terms of delivery week (p< 0.212; p< 0.149). Regardless of the technique applied, no statistically significant difference was observed between cervical length and birth < 34 weeks. Conclusion Our study found that pessary use for cervical insufficiency is statistically more effective than cervical cerclage surgery in preventing preterm births < 34 weeks in singleton pregnancy.

Abstract Objective It is well known that female infertility is multifactorial. Therefore, we aimed to compare the effects of thyroid dysfunction, vitamin deficiency, and microelement deficiency in fertile and infertile patients. Materials and Methods Between May 1st, 2017, and April 1st, 2019, we conducted a retrospective case-control study with of 380 infertile and 346 pregnant patients (who normally fertile and able to conceive spontaneously). The fertile patients were selected among those who got pregnant spontaneously without treatment, had a term birth, and did not have systemic or obstetric diseases. The levels of thyroid-stimulating hormone (TSH), triiodothyronine (T3), thyroxine (T4), anti-thyroid peroxidase (anti-TPO), vitamin D, vitamin B12, folic acid, ferritin, and zinc of both groups were compared. Results There was no difference between patients in the infertile and pregnant groups in terms of low normal and high serum T3 and T4 levels (p = 0.938; p > 0.05) respectively, nor in terms of normal and high anti-TPO levels (p = 0.182; p > 0.05) respectively. There was no significant difference regarding patients with low, insufficient, and sufficient vitamin D levels in the infertile and pregnant groups (p = 0.160; p >0.05) respectively. The levels of folic acid, ferritin, and zinc of the infertile group were significantly lower than those of the pregnant group. Conclusion The serum levels of folic acid, ferritin, and zinc in infertile patients presenting to our outpatient clinic were lower than those o the fertile patients.

Objective: This study aims to compare the perinatal outcomes of emergency and elective cervical cerclages. Material and Methods: This retrospective study included a total of 247 patients, with a total of 142 emergency (with a history of mid-trimester miscarriage or vaginal delivery of < 34 weeks and cervical length < 25 mm) and 105 electives cerclage patients (with painless cervical dilation and cervical length
