Association between Peripartum Mean Arterial Pressure and Postpartum Readmission for Preeclampsia with Severe Features.

Objective: This study aimed to evaluate the relationship between peripartum mean arterial pressure (MAP) and postpartum readmission for preeclampsia with severe features.

Study Design: This is a retrospective case-control study comparing adult parturients readmitted for preeclampsia with severe features to matched nonreadmitted controls. Our primary objective was to evaluate the association between MAP at three time points during the index hospitalization (admission, 24-hour postpartum, and discharge) and readmission risk.

Identification and isolation of putative stem cells from the murine placenta.

Objective: The placenta of mid-gestation mice is a known rich source of hematopoietic stem cells. We hypothesized that it is also a source of other multipotent stem cells.

Methods: We isolated fetal cells from the murine placenta across the second half of gestation and characterized their expression of surface antigens known to be associated with mesenchymal stem cells (MSCs) on a subset of hematopoietic lineage-negative cells.

Controlled fine needle biopsy of the uterine cervix during pregnancy.

Objective: Cervical sampling could furnish tissue-based information regarding premature cervical ripening and effacement. This report assesses the effect of cervical fine needle biopsy (FNB) in the evaluation of cervical shortening.

Methods: Retrospective cohort study evaluating adverse events during the first week following FNB in women with short cervix.

Prematurity in twin pregnancies.

Preterm birth (PTB) is a leading cause of adverse perinatal outcome, including both neonatal morbidity and mortality. This condition has been directly associated with the consistently rising incidence of multiple gestations over the past three decades. Twin gestation, the most common form of multiple gestation, represents a unique subgroup of fetuses at high risk for prematurity.

Hemolytic transfusion reaction after preoperative prophylactic blood transfusion for sickle cell disease in pregnancy.

Background: Preoperative transfusions are frequently given to prevent morbidity in nonpregnant patients with sickle cell disease. We describe a case of a life-threatening delayed hemolytic transfusion reaction with hyperhemolysis syndrome in pregnancy.

Case: A multigravida with sickle cell disease underwent prophylactic blood transfusion before repeat cesarean delivery.
