Objective: To determine whether a greater proportion of fetuses in an Asian Indian cohort are classified as small for gestational age than would be expected from a normally distributed population.
Methods: A retrospective analysis of fetal growth pattern and neonatal outcome was conducted among Asian Indian women who were referred to a maternal-fetal medicine center in Park Ridge, IL, USA, for evaluation of fetal growth between January 1, 2012, and December 31, 2013. The primary outcome was an abdominal circumference or estimated weight of lower than the 10th percentile for gestational age according to the Hadlock formula.
Results: Overall, 207 women and 210 fetuses were included. Forty-eight (22.9%) fetuses had an abdominal circumference lower than the 10th percentile. The total number of neonates classified as small for gestational age at delivery was 22 (10.5%), a value indicative of a normally distributed population.
Conclusion: Fetal size was smaller than expected among the present Asian Indian cohort, but most neonates were classified as appropriate for gestational age at birth. Population specific growth curves are needed to improve assessment of fetal growth.

Insufficient trophoblast cell infiltration is implicated in the progression of preeclampsia (PE). The immunoglobulin superfamily member 8 (IGSF8) has been shown to promote cell migration, invasion, and epithelial mesenchymal transition (EMT). However, the specific impact of IGSF8 on trophoblast cells in PE has not been definitively demonstrated.

Exposure to psychosocial stress during pregnancy has been associated with the emergence of neurodevelopmental and neuropsychiatric disorders in offspring. The placenta is known to orchestrate various functions that are essential for normal fetal development, including the brain. It has therefore been postulated that alterations in such functions, and downstream signaling, have the potential to dramatically affect brain developmental trajectories and contribute to adverse neurodevelopmental outcomes.

Introduction: The placenta produces corticotrophin releasing hormone (CRH), which rises exponentially in maternal plasma across pregnancy. CRH plays a functional role in fetal development, labor initiation, and the regulation of gestational length. We aimed to understand how maternal plasma CRH during pregnancy reflects placental physiology during parturition by characterizing placental transcriptomic signatures of maternal plasma CRH and comparing to transcriptomic signatures of gestational age at birth.

Aims: Human periodontal ligament stem cells (hPDLSCs) exhibit an enormous potential to regenerate periodontal tissue. However, their translatability to the clinical setting is constrained by technical difficulties in standardizing culture conditions. The aim was to assess complex culture conditions using a proteomic-based protocol to standardize multi-layer hPDLSC cultivation methodology.

Robust preclinical models of asymmetric ventricular loading in late gestation reflecting conditions such as hypoplastic left heart syndrome are lacking. We characterized the morphometry and microvascular function of the hypoplastic left ventricle (LV) and remaining right ventricle (RV) in a sham-controlled late gestation fetal lamb model of impaired left ventricular inflow (ILVI). Singleton fetuses were instrumented at ∼120 days gestational age (dGA; term is ∼147 days) with vascular catheters, an aortic flow probe and a deflated left atrial balloon.
