Article Abstract
Background: Hypertensive pregnancies are associated with an increased risk of cardiovascular and neurological diseases in the offspring during later life. However, less is known about the potential impact on multi-organ phenotypes in offspring before disease symptoms occur. The objective of this systematic review was to determine the associations of fetal exposure to maternal hypertensive pregnancy with multi-organ phenotypes across developmental stages.
Methods And Results: Ovid MEDLINE, EMBASE, CENTRAL (Cochrane Central Register of Controlled Trials), WoS, Scopus, CINAHL, and ClinicalTrials.gov were systematically searched until February 2024. Records were independently screened by 2 authors. Studies reporting on the structure or function of the heart, blood vessels, brain, liver, and kidneys in offspring of hypertensive pregnancies compared with a normotensive control population were included. Risk of bias was assessed using the Newcastle-Ottawa Scale. Extracted data were presented using harvest plots. Seventy-three studies including 7091 offspring of hypertensive pregnancies and 42 164 controls were identified that met the inclusion criteria. Thirty-two studies were investigations in fetuses, 24 in neonates and infants, 12 in children, 2 in adolescents, and 3 in adults. Offspring of hypertensive pregnancies had structural and functional changes in the heart compared with controls in some studies across developmental stages. Offspring of hypertensive pregnancies also had smaller occipital and parietal vessels, higher aortic intima-media thickness, and lower retinal arteriolar-to-venular ratio. Some conflicting evidence existed for other phenotypical alterations.
Conclusions: There is still inconsistent evidence of multi-organ structural and functional differences in offspring of hypertensive pregnancies. The evidence base could therefore be further strengthened through well-designed and conducted prospective studies.

Impact of fertility treatments on perinatal outcomes in pregnancies complicated by GDMA1: a comparative cohort study.

Objective: To investigate adverse pregnancy and delivery outcomes in women with GDMA1 during pregnancies conceived through fertility treatments.
Methods: This population-based retrospective cohort study examined adverse pregnancy and delivery outcomes in pregnancies affected by GDMA1 following fertility treatments compared to those conceived naturally. Women with GDMA1 who conceived via fertility treatments were classified as cases, while those who conceived naturally were designated as controls.
EXPRESS: Methylation levels of the LEP, LEPR, and ADIPOQ genes and their association with metabolically healthy obesity.

It has been reported that DNA methylation in the epigenetic profile of the genes LEP and ADIPOQ is associated with obesity. To the best of our knowledge, there are no previous reports assessing the methylation of the LEP, LEPR, and ADIPOQ genes in subjects with metabolically healthy obesity (MHO). Therefore, the aim of this study was to determine the association between methylation of the LEP, LEPR, and ADIPOQ genes with the MHO phenotype.

Vitamins, as essential m icronutrients, are vital for numerous cellular functions and play a key role in maintaining hematological parameter s during pregnancy, including erythropoiesis and processes affecting iron status. Iron-Deficient Gestational Anemia (IDGA), the most common clinicopathological condition in obstetrics and highly prevalent in developing countries, significantly contributes to complications such as hypertensive disorders of pregnancy and gestational diabetes. While it is recognized that vitamin deficiencies impact iron metabolism and erythropoiesis, a complete understanding of their specific roles in preventing and managing IDGA is lacking.

Background: Studies show that foetal and birthweight-for-gestational age centiles are poor predictors of serious neonatal morbidity and neonatal mortality (SNMM) in univariable models.
Objective: We assessed the predictive performance of multivariable SNMM models based on maternal/pregnancy characteristics, with and without birthweight centiles.
Methods: The study was based on all live births in the United States, 2019-2021, with data obtained from the period live birth-infant death files of the National Center for Health Statistics.
