Background: The in-utero environment affects fetal development; it is vital to understand how maternal diet during pregnancy influences childhood body composition. While research indicates that triglycerides in hyperglycaemic women may increase birth weight, little is known about this relationship in euglycemic women. This study examines the relationship between maternal blood lipid status and infant adiposity up to 2 years of age.
Methods: Data from 331 mother-child pairs from the ROLO longitudinal birth cohort study was analysed. Maternal dietary intakes were recorded and fasting blood lipids, leptin and HOMA were measured in early and late pregnancy and cord blood. Infant anthropometric measurements and skin-fold thicknesses were recorded at birth, 6 months and 2 years. Correlation and regression analyses were used to explore associations between maternal blood lipid status and infant adiposity.
Results: All maternal blood lipids increased significantly during pregnancy. Maternal dietary fat intake was positively associated with total cholesterol levels in early pregnancy. Late pregnancy triglycerides were positively associated with birth weight (P = 0.03) while cord blood triglycerides were negatively associated with birth weight (P = 0.01). Cord HDL-C was negatively associated with infant weight at 6 months (P = 0.005). No other maternal blood lipids were associated with infant weight or adiposity up to 2 years of age.
Conclusion: Maternal and fetal triglycerides were associated with birth weight and cord HDL-C with weight at 6 months. Thus, maternal lipid concentrations may exert in-utero influences on infant body composition. There may be potential to modulate infant body composition through alteration of maternal diet during pregnancy.

Objective: To describe the presentation, outcomes, and management strategies for cases of subcapsular liver hematoma associated with preeclampsia, eclampsia, or HELLP (hemolysis, elevated liver enzymes, and low platelet count) syndrome.
Methods: This was a case series of individuals with subcapsular liver hematoma managed at a single level IV center over a 10-year period, from 2013 to 2024. Presenting signs and symptoms, laboratory findings, time of onset, management strategies, acute perinatal and maternal outcomes, and long-term outcomes such as subsequent pregnancies were reviewed in the medical record and recorded.

Introduction: Placental DNA methylation differences have been associated with timing in gestation and pregnancy complications. Maternal cell-free DNA (cfDNA) partly originates from the placenta and could enable the minimally invasive study of placental DNA methylation dynamics. We will for the first time longitudinally investigate cfDNA methylation during pregnancy by using Methylated DNA Sequencing (MeD-seq), which is compatible with low cfDNA levels and has an extensive genome-wide coverage.

Alloimmunization during pregnancy occurs when a mother produces antibodies against fetal antigens, leading to complications like hemolytic disease of the fetus and newborn (HDFN) and fetal and neonatal alloimmune thrombocytopenia (FNAIT). HDFN involves destruction of fetal red blood cells, potentially causing severe anemia, hydrops fetalis, and fetal death. FNAIT affects fetal platelets and possibly endothelial cells, resulting in risk of intracranial hemorrhage and brain damage.

Background: Environmental factors are increasingly being recognized as significant contributors to Alzheimer's and Related Dementias (ADRD). Previously, we reported that higher serum concentrations of DDE, the highly persistent metabolite of the pesticide DDT was associated with increased risk of Alzheimer's disease. We further demonstrated in cell and animal models that DDT and DDE increase amyloid pathology in the brain (Fig.

Background: Hyperuricemia (HUA) is a condition characterized by excessive uric acid production and/or inadequate uric acid excretion due to abnormal purine metabolism in the human body. Uric acid deposits resulting from HUA can lead to complications such as renal damage. Currently, drugs used to treat HUA lack specificity and often come with specific toxic side effects.
