Doppler-derived myocardial performance index are used to assess aspects of systolic and diastolic function in adult as well as fetal heart. The Tei Index (TI) is a useful and non-invasive tool. The aim of this study was to determine normal values of fetal left ventricular (LV) TI in early (16-32 weeks) and late trimester (35-41 weeks) fetuses and to develop a new myocardial performance index (K-index; KI) which focuses on fetal diastolic interval when oxygenated blood from the placenta filled in the LV. Simultaneous recordings of Doppler Ultrasound Signal (DUS) of the LV outflow tracts and fetal electrocardiogram signals were obtained in 55 early- and late-trimester fetuses...

Context: Infants born small for gestational age (SGA) have increased risk for obesity and metabolic syndrome in future life, but the underlying mechanisms are not fully elucidated. Adipocyte fatty acid binding protein, is an adipokine that has been implicated in modulation of insulin sensitivity and lipid metabolism. Higher plasma AFABP levels are associated with increased risk of metabolic syndrome and cardiovascular morbidity in adults. Alterations in AFABP levels during fetal growth have not been characterized...

Background: Adequate sex steroid hormone concentrations are essential for normal fetal genital development in early pregnancy. Our previous study demonstrated an inverse relationship between third trimester di-ethyl hexyl (DEHP) phthalate exposure and total testosterone (TT) concentrations. Here, we examine early pregnancy phthalates, sex steroid hormone concentrations, and newborn reproductive outcomes. Methods: We examined associations between urinary phthalate metabolite concentrations in early pregnancy and serum free testosterone (FT), TT, estrone (E1), and estradiol (E2) in 591 woman/infant dyads in The Infant Development and Environment Study; we also examined relationships between hormones and newborn genital outcomes using multiple regression models with covariate adjustment...

Zika virus (ZIKV) infection in pregnancy is associated with adverse fetal outcomes, such as microcephaly and other congenital malformations. No therapeutic options are available to pregnant women with ZIKV infection to prevent these effects. Drug trials in pregnancy raise several scientific, ethical, and logistical challenges, which are compounded further in ZIKV because of limited knowledge of the disease pathophysiology and a product development pipeline in its infancy. We evaluate the major challenges in choosing therapeutics to prevent congenital ZIKV disease and conducting clinical trials of these treatments, with a focus on preventing congenital central nervous system malformations...

Hypertension and chronic kidney disease (CKD) have a significant impact on global morbidity and mortality. The Low Birth Weight and Nephron Number Working Group has prepared a consensus document aimed to address the relatively neglected issue for the developmental programming of hypertension and CKD. It emerged from a workshop held on April 2, 2016, including eminent internationally recognized experts in the field of obstetrics, neonatology, and nephrology. Through multidisciplinary engagement, the goal of the workshop was to highlight the association between fetal and childhood development and an increased risk of adult diseases, focusing on hypertension and CKD, and to suggest possible practical solutions for the future...

Genistein is one of the most abundant isoflavones in soybean. This molecule induces cell cycle arrest and apoptosis in different normal and cancer cells. Genistein has been of considerable interest due to its adverse effects on bovine reproduction, altering estrous cycle, implantation and fetal development and producing subfertility or infertility. The objective of this work was to study the effects of genistein on the expression of selected genes involved in the regulation of cell cycle and apoptosis. Primary cultures of bovine oviductal epithelial cells (BOEC) were treated with different genistein concentrations (0...

The first 1000 days of life is marked by intense metabolic activity and tissue deposition. The increased nutritional needs during this period, and the challenges to meeting them, are often not understood or appreciated. Here, we describe the nutritional needs during the first 1000 days, highlight the challenges to meeting these needs in developing countries, outline intervention strategies, and examine the consumption of small-quantity lipid-based nutrient supplements (SQ-LNS) as a promising strategy. In low-income settings, the challenge to meeting nutritional needs during the first 1000 days is worsened by overreliance on cereal-based diets of low nutrient density and high prevalence of infections and infestations...

Hypertension during pregnancy is the most common medical condition encountered during gestation. Despite this, knowledge of the mechanisms that underlie the disease and the development of new therapies are limited. Hypertension during pregnancy and some forms of cancer confer an increased risk to the development of cardiovascular disease later in life; one mechanism which may link these conditions is the involvement of natural killer (NK) cells. Whilst immunology and immunotherapy are well-developed areas in oncology; the complex mechanisms of the immune system in health and disease at the maternal-fetal interface are less well-defined...

Chronic fetal hypoxaemia is a common pregnancy complication that may arise from maternal, placental and/or fetal factors. Respiratory outcome of the infant at birth likely depends on the duration, timing and severity of the hypoxaemic insult. We have isolated the effect of maternal chronic hypoxia (MCH) for a month in late gestation on fetal lung development. Pregnant ewes were exposed to normoxia (21% O2 ) or hypoxia (10% O2 ) from 105-138 d gestation (term ∼145 d). At 138 d, gene expression in fetal lung tissue was determined by qRT-PCR...

BACKGROUND: To develop and evaluate a reconstruction framework for high resolution time-resolved CMR of the fetal heart in the presence of motion. METHODS: Data were acquired using a golden angle radial trajectory in seven fetal subjects and reconstructed as real-time images to detect fetal movement. Data acquired during through-plane motion were discarded whereas in-plane motion was corrected. A fetal cardiac gating signal was extracted to sort the corrected data by cardiac phase, allowing reconstruction of cine images...

The physical growth of young children in low- and middle-income countries is reduced compared to international standards. The deviations in growth in both weight and height are greatest in the first 2 years of life and this has serious consequences for child mortality, development, adult stature, and health. The determinants of these patterns of growth faltering include intergenerational factors, such as maternal height, short birth interval, and conditions in pregnancy, including maternal underweight and anemia...

BACKGROUND: Obstetrics and gynecology departments receive the smallest amount of National Institutes of Health (NIH) research funding and have significantly lower application success rates compared to pediatric, internal medicine, and surgery departments. The development of mentored early career development training grants (K awards) has been one strategy implemented by the NIH to help aspiring physician-scientists establish independent research careers. OBJECTIVE: The purpose of this study is to describe the cohort of ob/gyn physician-scientists who were K08, K12, and K23 recipients from 1988-2015 and to identify predictors of success in obtaining independent federal funding, as defined by acquisition of an R01, R21, R34, U01, U54, P01, or P50...

The aim of this review is to discuss three dimensional (3D) power Doppler of the placenta and its clinical applications. There is a strong clinical need to develop noninvasive, simple and widely available methods of evaluating in vivo placental function to assess fetal wellbeing. While conventional ultrasound is a proven tool in the evaluation of fetal structural anomalies and health, its ability to assess placental function, especially prior to the onset of fetal compromise, is the subject of ongoing investigation...

Tetralogy of fallot (TOF) is one of the most prevalent types of congenital heart diseases. As a category of bioactive molecules, peptides have been proved to participate in various biological processes. However, the role of endogenous peptides in the pathogenesis of TOF has not been studied. In this study, we performed a comparative peptidomic profile in the fetal heart of TOF and the control group for the first time by liquid chromatography-tandem mass spectrometry. Our data demonstrated that a total of 201 peptides derived from 176 precursor proteins were differentially expressed in the heart tissues of TOF fetuses compared with normal controls, including 41 upregulated peptides and 160 downregulated peptides...

Palliative surgery for congenital heart disease has allowed patients with previously lethal heart malformations to survive and, in most cases, to thrive. However, these procedures often place pressure and volume loads on the heart, and over time, these chronic loads can cause heart failure. Current therapeutic options for initial surgery and chronic heart failure that results from failed palliation are limited, in part, by the mammalian heart's low inherent capacity to form new cardiomyocytes. Surmounting the heart regeneration barrier would transform the treatment of congenital, as well as acquired, heart disease and likewise would enable development of personalized, in vitro cardiac disease models...

BACKGROUND AND PURPOSE: Offspring exposed to maternal diabetes are at increased risk of neurocognitive impairment, but its origins are unknown. With MR imaging, we investigated the feasibility of comprehensive assessment of brain metabolism ((1)H-MRS), microstructure (DWI), and macrostructure (structural MRI) in third-trimester fetuses in women with diabetes and determined normal ranges for the MR imaging parameters measured. MATERIALS AND METHODS: Women with singleton pregnancies with diabetes (n = 26) and healthy controls (n = 26) were recruited prospectively for MR imaging studies between 34 and 38 weeks' gestation...

Intra-individual variability (IIV) is defined as systematic within-person variation in performance either across test sessions (e.g., test/retest performance on the same task) or in one session (e.g., variations in performance on multiple trials of a single task). Higher levels of IIV have been noted as a characteristic of neurodevelopmental disorders such as attention deficit/hyperactivity disorder​ (ADHD), but IIV is yet to be investigated in fetal alcohol spectrum disorder (FASD). FASD is a term used to describe a range of conditions resulting from prenatal exposure to alcohol...
