Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is caused by maternal antibodies that cross the placenta in connection with pregnancy and destroy fetal platelets. Recently, maternal T cell responses associated with FNAIT have been studied at the clonal level. These T cell clones recognize an integrin β3 epitope, which is anchored to the HLA-DRB3∗0101-encoded MHC molecule DR52a. The same MHC allele is strongly associated with FNAIT. As the production of pathological antibodies reactive with fetal platelets is likely dependent on these T cell responses, there exists a potential for preventing FNAIT by targeting these T cells.

Introduction: The aim of this study was to evaluate differences in circulating maternal placental biomarkers and fetoplacental Dopplers in women with diabetes mellitus in pregnancy (DIP) with prenatally identified small fetuses (defined as <20th centile for gestational age) compared to women with small fetuses without DIP.

Methods: This was a prospective cohort study of women with DIP with small infants compared to a non-diabetic cohort with similarly small fetuses. Multivariable logistic regression was used to evaluate the effect of DIP on placental biomarkers, fetoplacental Dopplers, and adverse perinatal outcomes.

Background: Fetal midgut volvulus is a rare disease, with a high risk of potentially life-threatening fetal complications.

Purpose: The aim of this study was to retrospectively analyze the imaging findings of fetal midgut volvulus diagnosed by magnetic resonance imaging (MRI) and explore its value in non-invasive prenatal diagnosis.

Methods: A retrospective collection of data from 156 fetuses suspected of intestinal obstruction by ultrasound examination in our hospital was conducted.

Zinc (Zn) is one of the most prevalent and essential micronutrients, found in 10% of all human proteins and involved in numerous cellular enzymatic pathways. Zn is important in the neonatal brain, due to its involvement in neurotransmission, synaptic plasticity, and neural signaling. It acts as a neuronal modulator and is highly concentrated in certain brain regions, such as the hippocampus, and the retina.
