Society for Maternal-Fetal Medicine (SMFM) Consult Series #50: The role of activity restriction in obstetric management.

Am J Obstet Gynecol 2020 Apr 28. Epub 2020 Apr 28.

The Society for Maternal-Fetal Medicine: Publications Committee, 409 12th St, SW, Washington, DC 20024.

Despite current recommendations against its use, activity restriction remains a common intervention used to prevent preterm birth in multiple clinical settings. Hypertensive disorders of pregnancy, preterm premature rupture of membranes (PPROM), multiple gestations, vaginal bleeding, short cervical length, placenta previa, and fetal growth restriction (FGR) are also common reasons for antepartum hospital admission and frequently lead to a recommendation for activity restriction. However, numerous reports have shown that activity restriction does not prevent adverse obstetrical outcomes but does confer significant physical and psychosocial risks. Read More

Biomarkers of abnormally invasive placenta.

Placenta 2020 02 23;91:37-42. Epub 2020 Jan 23.

Department of Obstetrics and Gynecology, Hackensack University Medical Center, Hackensack, NJ 07601, USA.

Introduction: Abnormally invasive placenta (AIP, aka placenta accreta spectrum; PAS) is an increasingly common pregnancy pathology, which, despite significant morbidity risk to the mother, is often undiagnosed prior to delivery. We tested several potential biomarkers in plasma from PAS mothers to determine whether any were sufficiently robust for a formal, diagnostic accuracy study.

Methods: We examined hyperglycosylated hCG (h-hCG), decorin and IL-8, based on biological plausibility and literature indications that they might be altered in PAS. Read More
