Risk factors for perinatal mortality in patients admitted to the hospital with the diagnosis of placental abruption.

Objective: Placental abruption is a clinical term used when premature separation of the placenta from the uterine wall occurs prior to delivery of the fetus. Hypertension, substance abuse, smoking, intrauterine infection and recent trauma are risk factors for placental abruption. In this study, we sought for clinical factors that increase the risk for perinatal mortality in patients admitted to the hospital with the clinical diagnosis of placental abruption.

Thrombin regulates monocyte chemoattractant protein-1 expression in human first trimester and term decidual cells.

Objective: Excess decidual macrophage infiltration has been linked to preeclampsia and a failure of endovascular trophoblast invasion. Severe preeclampsia with shallow placentation has also been linked to acquired and inherited maternal thrombophilias and recurrent decidual hemorrhage, which generates thrombin from decidual cell-expressed tissue factor. Therefore, the current study evaluated whether thrombin affects monocyte chemoattractant protein-1 (MCP-1) expression in stromal cells that are derived from cycling and gestational endometrium.

Combined serum and ultrasound screening for detection of fetal aneuploidy.

Experience gathered over the last decade from high-risk centers provide strong evidence that mid-trimester sonographic markers are sensitive for Down syndrome prediction. More recent data indicate that combining mid trimester sonography with traditional serum markers significantly improves diagnostic accuracy over either group of markers by themselves.
