Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Our study examines the effects of oxytocin hormone receptors. mechanisms of placental tissue cells and therefore intrauterine development. It was conducted to investigate the effects on newborn babies apgar score, fontanel openings, birth weights, etc. By collecting data, normal and They were compared between cesarean births by statistical analysis. normal in this regard Based on the hypothesis that there is a difference between labor and cesarean delivery, this study has been made.OXTR primary antibody was used for immunohistochemical examination. There was no significant difference between the groups in terms of histological examination. In the study, it was found that OXTR immunoreactivity was strong in decidual cells and stromal cells in villi. A stronger OXTR immunoreactivity was detected in villous stroma of placenta of the natural birth group compared to the cesarean birth group. Reaction was not observed in syncytotrophoblast cells and syncytial nodes in both groups, but strong immunoreaction was observed fetal endothelial cells and fetal capillaries in both groups.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The aim of this study was to compare oxytocin receptor (OXTR) immunoreactivity in placentas obtained from women having cesarean and natural birth. The study samples consisted of placentas of 32 mothers who had 16 natural birth (control) and 16 cesarean (case) birth in Kars Harakani State Hospital and Kafkas University Health Research and Application Hospital. At the beginning of the study, 40 placentas obtained in total, 5 were not included in the study due to mismatched blood, 2 were not included in the study after the chronic disease (thyroid, Behçet's disease) detected, and 1 was not included in the study due to the presence of accessory placenta. The means of binary variables were determined by applying the Independent Two-Sample T-Test. Pearson Correlation analysis was used to examine the relationship between the variables. Periodic acid-Schiff staining, H\&E and Triple staining techniques were applied to tissue samples obtained from placentas for histological examination. OXTR primary antibody was used for immunohistochemical examination. There was no significant difference between the groups in terms of histological examination. In the study, it was found that OXTR immunoreactivity was strong in decidual cells and stromal cells in villi. A stronger OXTR immunoreactivity was detected in villous stroma of placenta of the natural birth group compared to the cesarean birth group. Reaction was not observed in syncytotrophoblast cells and syncytial nodes in both groups, but strong immunoreaction was observed fetal endothelial cells and fetal capillaries in both groups. As a result, it is thought that the placenta pathology should be made routine for every birth because it gives information about the offspring.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

"Our study was conducted on the placentas of 40 women admitted to the obstetrics clinics of Kars Harakani State Hospital and Kafkas University Training and Research Hospital, after obtaining necessary permissions. Out of 40 placentas, 5 were excluded due to blood incompatibility, 2 were excluded due to subsequent diagnosis of chronic conditions (thyroid disorder, Behçet's disease), and 1 was excluded due to the presence of an accessory placenta, resulting in a total of 32 placentas included in the study. Among these, 16 were from women who had undergone normal vaginal delivery (control group), and 16 were from women who had undergone cesarean section (case group). Tissue samples obtained from the placentas were subjected to histological and immunohistochemical methods to obtain various findings

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

experimental group

The group consists of mothers who meet the inclusion criteria specified in the study, have an 8cm dilation at term, and undergo cesarean section delivery.

Group Type ACTIVE_COMPARATOR

The delivery being performed via cesarean section surgery rather than natural childbirth

Intervention Type OTHER

At Kars Harakani State Hospital and Kafkas University, 16 placentas were collected, with 8 obtained from induced deliveries and 8 from spontaneous deliveries, between 09:00-21:00. Nulliparity and multiparity were not distinguished among the expectant mothers. Placentas were obtained hours before delivery from mothers admitted to the gynecology service, whose eligibility was determined based on exclusion criteria, after obtaining signed informed consent forms, with assurances given that no interventional procedures would be performed on the mother or the baby. The method of cesarean section (spinal or general anesthesia) in the case group was recorded, ensuring that the anesthetic agents used contained the same active ingredients. Placentas from births involving different anesthetic drugs were not included in the study, aiming to standardize the procedure.

control group

The group comprises healthy mothers who meet the inclusion criteria specified in the study, have an 8cm dilation at term, and give birth vaginally.
