Effects of secondary trimester maternal serum screening on the results of pregnancy

In our study it was aimed to research the relations between pregnancy complications and frequencies of maternal and fetal complications which can be observed after the further follow-ups with biochemical indicators in gravid individuals whom found to be risky in quad test.120 patients who applied and had their labors conducted in İstanbul Training and Research Hospital and took quad test AFP (alpha fetoprotein), HCG (human chorionic gonadotropin), uE3 (unconjugated estriol), inhibin-A are included in our study. Conclusions planned to be obtained in this study are, IUGR (intrauterine growth deficiency), macrosomia, gestational diabetes, preeclampsia and preterm birth. 64 (% 53, 4) out of 120 patients participated in the study had normal labors while 56 (%46, 6) of the patients had labors with caesarean birth. On 70 (%58.3) patients whom did not develop obstetric complications, AFP value calculated as average as 1.00±0.74 MoM, uE3 value calculated as  0.89±0.4 MoM, hCg value calculated as 0.97±0.5 MoM and inhibin A value calculated as an average of  0.95±0.5 MoM.  On 50 (%41.6) patients whom developed obstetric complications, AFP value found as average of 1,06±0,74, uE3 value found as 0.96±0.39 MoM, hCG value found as 0.99±0.77 MoM and Inhibin A value found as 1.023±0.62 MoM. There were no significant deviation between the cases with obstetric complications and cases without obstetric complications in terms of AFP, uE3, HCG and Inhibin A values. There were no significant relation between threshold values of AFP, HCG, uE3 and inhibin A which are used in quad test as secondary trimester serum indicators in low risk populations and pregnancy complications

Cytogenetic analysis of early pregnancy loss after assisted reproduction treatment using intracytoplasmic sperm injection

Objectives: To evaluate the incidence of numerical chromosomal abnormalities in the patients with early pregnancy loss (EPL) following in vitro fertilization, and evaluate the role of different confounders of the risk of chromosomal abnormality-related pregnancy loss.Material and methods: A retrospective chart review of all patients from our in vitro fertilization (IVF) center who conceived using assisted reproduction techniques between April 2017 and 2019, who experienced a subsequent early pregnancy loss, and whose abortus materials were successfully karyotyped were included.Results: Of the 243 patients experienced an early loss, the overall rate of chromosomal abnormality was 46.75%. The overall rate of aneuploidy in our patient group was 88.8% (64/72), whereas 6.94% (5/72) of the abnormal karyotypes were polyploid. The most common type of trisomy was Trisomy 16 (20.0%; 11/55) followed by Trisomy 15 (14.5%; 8/55). Univariate and multivariate analyses showed that maternal age (< 35 years) and the total number of retrieved oocytes per cycle (≥ 5) were risk factors for a chromosomal abnormality (< 0.001; < 0.05, respectively). The adjusted OR of karyotypic abnormalities was 0.45 for the antagonist cycle type (p < 0.05), and 0.58 for frozen embryo transfer (p < 0.05).Conclusions: Karyotypic abnormality is one of the main reasons for pregnancy loss following an IVF procedure. Although the pregnancy rates increased as a result of novel technologies, the ratio of EPL is still high. The implementation of preimplantation genetic screening techniques might lower the incidence of EPL due to chromosomal abnormalities, thus decreasing the burden on the physicians and the patients

Borderline ovarian tumors: clinical characteristics, management, and outcomes - a multicenter study

Background: The optimal surgical management and staging of borderline ovarian tumors (BOTs) are controversial. Institutions have different surgical approaches for the treatment of BOTs. Here, we performed a retrospective review of clinical characteristics, surgical management and surgical outcomes, and sought to identify variables affecting disease-free survival (DFS) and overall survival (OS) in patients with BOTs
