Article Synopsis
  • * Researchers used a mouse model to study the effects of the AT2R agonist, compound [C], on PE symptoms, particularly looking at levels of soluble fms-like tyrosine kinase 1 (sFlt-1) and blood pressure.
  • * The findings indicated that compound [C] reduced sFlt-1 and improved hypertension, suggesting it could be a potential treatment for preeclampsia by influencing its pathological mechanisms.

Hydrops fetalis, characterized by abnormal fluid accumulation in fetuses, presents a significant risk of stillbirth and neonatal mortality. Although the etiology of nonimmune hydrops fetalis (NIHF) is multifaceted, recent studies have highlighted genetic factors as crucial determinants. This study focused on a family with three consecutive stillbirths, each with pronounced hydrops fetalis.

Preeclampsia (PE) is a serious disease that can be fatal for the mother and fetus. The two-stage theory has been proposed as its cause, with the first stage comprising poor placentation associated with the failure of fertilized egg implantation. Successful implantation and placentation require maternal immunotolerance of the fertilized egg as a semi-allograft and appropriate extravillous trophoblast (EVT) invasion of the decidua and myometrium.

The pathogenesis of preeclampsia begins when a fertilized egg infiltrates the decidua, resulting in implantation failure (e.g., due to extravillous trophoblast infiltration disturbance and abnormal spiral artery remodeling).

Article Synopsis
  • This study investigates the prevalence and antibiotic resistance of a specific bacterium in the urogenital tracts of pregnant women, especially focusing on its links to complications like pelvic inflammatory disease and infections after cesarean sections.
  • Of the 1074 tested specimens, 5.9% tested positive, with the highest rate (21.3%) found in women aged 18-24, and significant rates of positivity in patients with bacterial vaginosis and those undergoing cesarean sections.
  • Antibiotic resistance was noted for β-lactam antibiotics and macrolides, while clindamycin, minocycline, and quinolones showed effectiveness; clindamycin is particularly recommended for treating pregnant patients due to

The introduction of laparoscopic surgery has also been beneficial for patients with gynecological malignancies. In this respect, surgeons should receive related training in the context of human resource development. Hands-on training was introduced using Thiel-embalmed human cadavers (THCs) in 2014.

Objective: High-mobility group A1 (HMGA1) protein is known to express in trophoblast; however, the role of migration has not been reported to date. In this study, we investigated the role of HMGA1 on the pathogenesis of preeclampsia using immortalized human trophoblast cell (HTR-8/SVneo).

Materials And Methods: We investigated HMGA1 expression in cytotrophoblasts derived from our preeclampsia model mouse, the CD40L mouse, using immunofluorescence.

Multiple techniques have been used for the conservative treatment of high-grade cervical intraepithelial neoplasia (HG-CIN) in women of fertile age. Conization has been associated with stenosis of the cervix and a decrease in cervical mucus secretion, in addition to the increase in the risk of cervical canal shortening and problems during the perinatal period, including premature birth and premature rupture of membranes. Although the laser transpiration technique does not cause shortening of the cervical canal, it is associated with the recurrent risk of deep residual disease.

The CD40 ligand (CD40L) is expressed by T cells and has a critical role in immune system regulation. Interventions targeting CD40L interactions following embryo implantation represent an approach to preventing preeclampsia (PE). To better understand the role of CD40L in PE, we developed a PE mouse model in which we examined how CD40L-induced immune activation affects embryo implantation.

Owing to progress in perinatal medicine, the survival of preterm newborns has markedly increased. However, the incidence of cerebral palsy has risen in association with increased preterm birth. Cerebral palsy is largely caused by cerebral hypoxic ischemia (HI), for which there are no effective medical treatments.
