An analysis of placental chorionic villous and decidual basalis tissue immunoreactivity in patients after cesarean section due to a placenta accreta spectrum disorder and elective cesarean section followed by the depressed mood.

Unlabelled: An analysis of placental chorionic villous and decidual basalis tissue immunoreactivity in patients after cesarean section due to a placenta accreta spectrum disorder and elective cesarean section followed by a depressed mood.

Research Background: Over the past few years, interest in investigating immune dysfunction in patients with psychiatric disorders has increased. B7-H4 is a molecule with immunosuppressive properties that seems to play a key role in establishing maternal tolerance against fetal antigens.

FOXP3-positive cell infiltration in the chorionic villi is increased in the placenta accreta and decreased in the placental abruption.

Objectives: Growing data suggest a role of Treg cells in placentation. The aim of the study was to evaluate Treg cells (FOXP3-positive cells) placental bed infiltration in patients with placenta accrete syndrome (PAS) and patients who experienced placental abruption.

Material And Methods: The study group included 13 patients with PAS and the control group consisted of 66 women who had caesarean (CD) delivery of whom, 44 patients with elective caesarean (EC) delivery, and 22 patients with urgent caesarean (UC) delivery due to placental abruption.

Expression of the Costimulatory Molecule B7-H4 in the Decidua and Placental Tissues in Patients with Placental Abruption.

B7 homolog 4 protein (B7-H4), a member of the B7 family, is a immunomodulatory membrane protein. The aim of the study was to evaluate the expression of this protein in the decidua and placental tissues in case of placental abruption (PA) compared to cases of retained placental tissue (RPT) and controls. Tissue samples were obtained from 47 patients with PA, 60 patients with RPT, and 41 healthy controls.

Levonorgestrel-Releasing Intrauterine System as a Contraceptive Method in Nulliparous Women: A Systematic Review.

The aim of this review was to summarize the available evidence about the use of levonorgestrel-releasing intrauterine system (LNG-IUS) as a contraceptive method in nulliparous women. For this purpose, studies evaluating the efficacy, safety, bleeding pattern, satisfaction and discontinuation of the levonorgestrel-releasing intrauterine system in nulliparous women were analyzed. Only original research articles published in English between 1990-27th March 2020 were considered eligible.

Psychiatric disorders and changes in immune response in labor and postpartum.

Women may present with psychiatric disorders during pregnancy, normal labor, following delivery by caesarean section, or in the postpartum period. The accumulating evidence suggests that these disorders may be due to changes in immune responses. During pregnancy complications such as the prolongation of cervical ripening or descent, placental abruption, premature labor, and preeclampsia increase the risk of postpartum psychiatric disorders.

High tumor cell vimentin expression indicates prolonged survival in patients with ovarian malignant tumors.

Objectives: The main aims of the study were to investigate the expression of vimentin and its correlation with the overall survival (OS) of patients with malignant ovarian tumors, and the correlation between vimentin expression and tumor stroma characteristics.

Material And Methods: The study focused on 94 malignant ovarian tumors that had been collected from women who were treated in the Department of Gynecology and Oncology of the Lukaszczyk Oncological Center, Bydgoszcz, Poland. Vimentin expression was assessed in both the cancer cells (expression intensity and quantitative analysis) and the tumor stroma (expression intensity).
