Comparative analysis of thiol-disulfide homeostasis dynamics between elective cesarean section and uncomplicated vaginal delivery: insights into perinatal oxidative balance.

Objective: Thiols are organic compounds containing sulfhydryl groups that exert antioxidant effects via dynamic thiol-disulfide homeostasis. The shift towards disulfide indicates the presence of an oxidative environment. Different modes of delivery can affect thiol-disulfide homeostasis.

Histopathological examination of the curettage material in nonviable pregnancies and evaluation of the frequency of hydatidiform mole.

Aim: The study aimed to determine the frequency of possible missed diagnosis of gestational trophoblastic disease in nonviable pregnancies and to evaluate the importance of histopathological examination.

Methods: In this retrospective study, the results of the histopathological assessment of patients undergoing uterine surgery with a diagnosis of nonviable pregnancy were analyzed before 14 weeks of gestation. Nonviable pregnancy was defined as anembryonic pregnancy and intrauterine exitus (IU-ex) based on ultrasound findings.

Sonographic measurement of the fetal thymus: Relationship with maternal obesity.

Background: The purpose of this study was to evaluate the influence of maternal obesity on the size of the fetal thymus.

Methods: The study population consisted of 138 pregnant women who were divided into two groups based on their body mass index (BMI): Normal-weight group (n = 97; BMI: 18-25 kg/m ) and obese group (n = 41; BMI: ≥ 30 kg/m ). All participants underwent routine second-trimester prenatal ultrasound (US) screening at 20-25 weeks of gestation.

Evaluation of oxidative stress markers and intra-extracellular antioxidant activities in patients with endometriosis.

Objective: The aim of the study is to evaluate alterations in intracellular and extracellular antioxidant enzymes activities and serum oxidative stress markers in patients with endometriosis.

Study Design: The current prospective study consisted of 31 female patients with endometriosis and 27 healthy controls. Serum total thiol, native thiol, disulphide, catalase, myeloperoxidase, and ceruloplasmin concentrations were measured.

Dynamic thiol-disulfide homeostasis in hyperemesis gravidarum.

Objective: To determine serum thiol-disulfide homeostasis in hyperemesis gravidarum.

Study Design: Twenty-six pregnant women with hyperemesis gravidarum and 37 healthy pregnant women were included in the study. Native thiol, disulfide and total thiol concentrations were measured with a novel automated method.
