OBJECTIVES: Placental weight (PW) and fetal/placental weight ratio (F/P) have been considered to be useful parameters for understanding the pathophysiology of fetal growth. However, there have been no standard data on PW and F/P in Asian populations. This study was conducted to establish nomograms of PW and F/P in the Japanese population and to clarify characteristics of PW and F/P in this population. STUDY DESIGN: Included in the study were 79,590 Japanese cases: 58,871 vaginal and 20,719 cesarean deliveries at obstetrical facilities (2001-2002) and registered to the Japan Society of Obstetrics and Gynecology Database...

The placenta is the critical interface between the mother and the developing fetus and is essential for survival and growth. Despite the widespread use of ultrasound imaging and Doppler in obstetrics and gynecology and the recent growth of elastographic technologies, little is known about the biomechanical (elastic shear wave) properties of the placenta and the range of normal and pathologic parameters that are present. This study uses a well-developed protocol for perfusing whole placentas, post-delivery, to maintain tissue integrity and function for hours...

BACKGROUND: The American College of Obstetrics and Gynecology (ACOG) and Maternal Fetal Medicine (MFM) Societies recommended that abnormal cfDNA fetal results should be confirmed by amniocentesis and karyotyping. Our results demonstrate that normal cfDNA results inconsistent with high-resolution abnormal ultrasounds should be confirmed by karyotyping following a substantial frequency of incorrect cfDNA results. METHODS: Historical review of our ~4,000 signed prenatal karyotypes found ~24% of reported abnormalities would not have been detected by cfDNA...

BACKGROUND: Clamping and cutting of the umbilical cord is the most prevalent of all operations, but the optimal timing of cord clamping is controversial, with different timings offering advantages and disadvantages. This study, for the first time, compares the influence of early and late cord clamping in correlation with oxidative stress and inflammation signaling, Because cord clamping timing may have a significant influence on placenta-to-infant blood transfer, thereby modifying oxygenation of maternal and fetal tissues, and on the transfer of inflammatory mediators throughout the placenta...
