Transplacental Transport Rates of Anti-pertussis Toxin-IgG and Anti-filamentous Hemagglutinin-IgG Antibodies in Newborns by Week of Birth.

Objective:  The aim of this study is to investigate the lack of knowledge about the transplacental transport of antibodies in unvaccinated term and preterm infants and possible differences in antibody-mediated immunity in the fetus depending on maternal vaccination in their own infancy.

Study Design:  The study was conducted as a prospective cross-sectional study between 2017 and 2018 and included a total of 334 participants. The study included 194 pregnant women with a preterm birth (before 37 weeks) and 140 pregnant women with a term birth.

Untargeted Metabolomic Biomarker Discovery for the Detection of Ectopic Pregnancy.

Ectopic pregnancy (EP) is the leading cause of maternal morbidity and mortality in the first trimester. Using an untargeted metabolomic approach, we sought to identify putative plasma biomarkers using tandem liquid chromatography-mass spectrometry for the detection of tubal EP. This case-control study included the prospective recruitment of 50 tubal EP cases and 50 early intrauterine pregnancy controls.

Material Methods: This is a multicenter study including data of 10 Gynecological Oncology Departments. Frozen-section results of patients who had ovarian AGCT at the final pathology report were retrospectively analyzed.

Defining the relationship between ovarian adult granulosa cell tumors and synchronous endometrial pathology: Does ovarian tumor size correlate with endometrial cancer?

Objective: The main feature of adult granulosa cell tumors (AGCT) is their capacity to secrete hormones, with nearly all of them capable of synthesizing oestradiol. The primary goal of this study is to identify synchronized endometrial pathologies, particularly endometrial cancer, in AGCT patients who had undergone a hysterectomy.

Materials And Methods: The study cohort comprised retrospectively of 316 AGCT patients from 10 tertiary gynecological oncology centers.

This study aimed to determine whether serum mid-luteal progesterone (MLP) levels measured in the current treatment cycles of infertile women undergoing controlled ovarian hyperstimulation and intrauterine insemination following the sequential use of clomiphene citrate and gonadotropin may predict pregnancy. A total of 107 consecutive anovulatory women were included in this prospective cohort study. Patients with other causes of infertility were also excluded from the study.

Is There a Predictable Cost-Benefit Ratio in Preeclampsia?

Background Preeclampsia (PE) is one of the highest-risk pregnancies and a complicated condition that occurs in 2% to 8% of pregnancies and is associated with markers of a systemic inflammatory response (SIR). In this study, we aimed to determine the role of these markers in predicting PE. Methodology A total of 300 women with singleton pregnancies and cephalic presentation were included in the study.

Early or late response in poor responders: does it make a difference in cycle outcome?

Ovarian response to stimulation mainly determines the length of stimulation. However, there is no clarity in the literature regarding the optimal duration required to achieve oocyte maturity in patients with the poor ovarian response (POR) defined by Bologna criteria. Therefore, a total of 267 cycles that fulfilled the inclusion criteria were selected retrospectively.

Objective: To assess the effect of cabergoline on endometrial vascular endothelial growth factor receptor-2 (VEGFR-2) immunoexpression in an ovarian hyperstimulation syndrome (OHSS) rat model.

Material And Methods: Twenty-one immature female Wistar rats were assigned into three groups: group 1, the control group; group 2, stimulated with gonadotropins to mimic OHSS; and group 3, in which an OHSS protocol was induced and thereafter treated with cabergoline (100 μg/kg/day). Body weight, ovarian volume, corpora lutea numbers, and endometrial VEGFR-2 expression were compared between the groups.

Cysteinyl Leukotriene and Systemic Inflammatory Levels in Preeclampsia.

Background In this study, we aimed to demonstrate the efficacy of cysteinyl leukotriene levels, which play a role in inflammation, in predicting the severity of preeclampsia (PE) and to determine whether this marker can be used as a screening tool. Methods In this cross-sectional analytic study, we classified pregnant women who were normotensive (control) or PE or severe PE (SPE) between March 2019 and July 2019. Singleton pregnant 60 women who met the following criteria for the diagnosis of PE were included in the study group.

Serum and Follicular Fluid Thiol/Disulfide Homeostasis in Diminished Ovarian Reserve Patients Undergoing In Vitro Fertilization/Intracytoplasmic Sperm Injection Treatment.

Introduction: The etiologies of diminished ovarian reserve (DOR) are still poorly understood, and many factors such as age, autoimmunity, genetics, idiopathicity, iatrogenesis, and oxidative stress (OS) play a role. Oxidative cellular damage increases following reactive oxygen species (ROS)-induced aging. This is the first study to evaluate the serum and follicular fluid (FF) thiol/disulfide homeostasis in patients under 35 years of age with DOR undergoing in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI).

Placental abruption (PA) is an obstetric emergency. This study investigated the use of platelet indices in PA in its early stages to determine if it could aid in diagnosis. Sixty-two pregnant women with PA and 130 pregnant women who delivered due to idiopathic preterm delivery were included in this case-control study.

Evaluation of serum telomerase activity in normal-weight young girls with polycystic ovary syndrome and its relation to metabolic parameters.

Objectives: This study investigated the discriminative value of serum telomerase levels in polycystic ovary syndrome (PCOS) and its relation to metabolic parameters.

Methods: Patients aged 16-23 years old who visited an adolescent outpatient clinic were included in the study. Our study consisted of 45 non-obese girls with polycystic ovary syndrome (PCOS), while our control group consisted of 45 healthy girls with normal menstrual cycles and no signs of hyperandrogenism.
