With ongoing evolution of advanced ultrasound diagnostic in prenatal care the trend is to detect potential fetal anomalies in the first trimester if possible. Complex knowledge of normal fetal anatomy, embryology and ultrasound anatomy is important to be able to identify subtle abnormalities. In this review we demonstrate the possibilities of ultrasound imaging of fetal brain at late first trimester and describe normal central nervous system development week by week. Original images are presented.

Metabolic Profiles of Pregnancy with Polycystic Ovary Syndrome: Insights into Maternal-Fetal Metabolic Communication.
J Clin Endocrinol Metab
January 2025
Department of Obstetrics and Gynecology, Women and Children's Hospital of Chongqing Medical University (Chongqing Health Center for Women and Children), Chongqing, China.
Context: PCOS pregnancies are linked to metabolic disorders affecting maternal and fetal outcomes, with maternal metabolites differing from those in normal pregnancies.
Objective: To investigate the metabolic communication at the maternal-fetal interface in PCOS pregnancies.
Design: Placenta and umbilical cord serum were analyzed using gas chromatography-mass spectrometry.
Potential for application of direct thrombin inhibitors isolated from Euphorbia resinifera O.Berg latex in fibrin clot formation.

Direct thrombin inhibitors (designated as EuRL-DTIs) were partially purified from ethanol extracts of Euphorbia resinifera O.Berg latex. The obtained EuRL-DTIs comprised four major compounds: two isomers of phenolic compounds (CHO) and two amide compounds (tentatively identified as CHNO and CHNO), as identified by liquid chromatography and electrospray ionisation quadrupole time-of-flight mass spectrometry (LC-ESI-QTOF-MS/MS), attenuated total reflection-Fourier transform infrared (ATR-FTIR) spectroscopy, and/or nuclear magnetic resonance (NMR) spectroscopy.

The glomerular filtration barrier (GFB) has a unique spatial structure, including porous capillary endothelial cells, glomerular basal membrane (GBM) and highly specialized podocytes. This special structure is essential for the hemofiltration process of nephrons. GBM is the central meshwork structure of GFB formed by the assembly and fusion of various extracellular matrix (ECM) macromolecules, such as laminins and collagens, which undergo isoform transformation and maturation that may require precise regulation by metalloproteinases.

Periparturient dairy cows experience metabolic adaptations to prepare for increased nutrient requirements of the fetus and the onset of lactation. Adaptations include increased peripheral tissue insulin resistance, which can be evaluated experimentally using intravenous glucose tolerance tests (IVGTT). The objective of this study was to determine if prepartum skeletal muscle reserves and supplementation of branched-chain volatile fatty acids (BCVFA) in the prepartum period affected blood glucose, β-hydroxybutyrate (BHB), and insulin concentrations 2 wk prepartum and 1 wk postpartum utilizing an IVGTT.

Department of Ultrasound, Shanghai Changning Maternity and Infant Health Hospital, East China Normal University, Shanghai 200050, China.
Background: The incidence of multiple pregnancies has increased worldwide recently and women with a twin pregnancy are at higher risk of adverse outcomes compared with women with a singleton pregnancy. It is important to understand the risk factors for adverse fetal outcomes in twin pregnancy in order to guide clinical management.
Aim: To identify the independent risk factors, including maternal personal and family medical histories and first trimester ultrasound screening findings, for adverse fetal outcomes of twin pregnancy before 28 weeks of gestation.
