OBJECTIVE: To assess whether the high soluble fms-like tyrosine kinase-1 (sFlt-1) to placental growth factor (PlGF) ratio is associated with adverse outcomes (e.g., HELLP syndrome [hemolysis, elevated liver enzymes, and low platelets], severe hypertension uncontrolled by medication, non-reassuring fetal status, placental abruption, pulmonary edema, growth arrest, maternal death, or fetal death) and a shorter duration to delivery in early-onset fetal growth restriction (FGR). METHODS: Thirty-four women with FGR diagnosed at <34...

Ovarian cancer is one of the most common types of solid carcinoma diagnosed during pregnancy. Taxane plus a platinum derivative is a combination therapy that is predominantly used in the treatment of ovarian cancer in non-pregnant women. Pregnancy adds various complexities to a course of treatment. In pregnant patients diagnosed with cancer during the first trimester, the risks of fetal malformations and fetal loss increase following the administration of cytotoxic drugs, and this is higher with multi-agent vs...

Intrauterine growth restriction in animal models reduces heart size and cardiomyocyte number at birth. Such incomplete cardiomyocyte endowment is believed to increase susceptibility toward cardiovascular disease in adulthood, a phenomenon referred to as developmental programming. We have previously described a mouse model of impaired myocardial development leading to a 25% reduction of cardiomyocyte number in neonates. This study investigated the response of these hypoplastic hearts to pressure overload in adulthood, applied by abdominal aortic constriction (AAC)...

PURPOSE: To investigate the ability of three-dimensional (3D) MRI placental shape and textural features to predict fetal growth restriction (FGR) and birth weight (BW) for both healthy and FGR fetuses. MATERIALS AND METHODS: We recruited two groups of pregnant volunteers between 18 and 39 weeks of gestation; 46 healthy subjects and 34 FGR. Both groups underwent fetal MR imaging on a 1.5 Tesla GE scanner using an eight-channel receiver coil. We acquired T2-weighted images on either the coronal or the axial plane to obtain MR volumes with a slice thickness of either 4 or 8 mm covering the full placenta...

Congenital cytomegalovirus (CMV) infection is the leading cause for sensorineural hearing loss and mental retardation in children without genetic diseases worldwide. There is little evidence guiding therapeutic strategies during pregnancy when intrauterine fetal CMV infection is confirmed. We provide a systematic review of the use of ganciclovir (GCV) or VGCV during pregnancy discussing safety of its use for mother and fetus and describe two cases of intrauterine therapy of fetal CMV infection with valganciclovir (VGCV)...

Fetal growth restriction in early pregnancy increases the risk of adverse pregnancy outcome, which has a significant social and psychological impact on women. There is limited information related to community-based study to evaluate early indicators related to miscarriage. The aim of this study is to examine the relationship between fetal growth restriction, measured by ultrasound crown-rump length (CRL), and subsequent occurrence of miscarriage in pregnant women in rural Bangladesh. The study was conducted within the Maternal and Infant Nutrition Interventions Trial in Matlab (MINIMat study), Bangladesh...

Mammalian target of rapamycin (mTOR) and autophagy have been implied in trophoblast cells proliferation and invasion. This study investigated whether mTOR and autophagy were involved in placental development and fetal programming. A total of 90 term normal placentas (37-42 gestational weeks) were collected from women who underwent elective cesarean section, with large for gestational age (LGA), fetal growth restriction (FGR), and appropriate for gestational age (AGA) infants (n=30, respectively). Capillary volume density within peripheral villi significantly decreased in the FGR placentas compared with the AGA group (p<0...

Poor maternal nutrition during gestation has been linked to poor growth and development, metabolic dysfunction, impaired health, and reduced productivity of offspring in many species. Poor maternal nutrition can be defined as an excess or restriction of overall nutrients or specific macro- or micronutrients in the diet of the mother during gestation. Interestingly, there are several reports that both restricted- and over-feeding during gestation negatively affect offspring postnatal growth with reduced muscle and bone deposition, increased adipose accumulation, and metabolic dysregulation through reduced leptin and insulin sensitivity...

Compromised placental function can result in fetal growth restriction which is associated with greater risk of neonatal morbidity and mortality. Large increases in transplacental nutrient and waste exchange, which support the exponential increase in fetal growth during the last half of gestation, are dependent primarily on the rapid growth and vascularization of the uteroplacenta. The amplitude of melatonin secretion has been associated with improved oxidative status and altered cardiovascular function in several mammalian species; however, melatonin mediated alterations of uteroplacental capacity in sheep and cattle are lacking...

Maternal exposure to particulate matter with aerodynamic diameter <10μm (PM10) during pregnancy results in adverse birth outcomes. Changes in placental DNA methylation might mediate those adverse effects. In this study, we examined the associations between prenatal PM10 exposure and DNA methylation of LINE1, HSD11B2 and NR3C1 in human placenta. One hundred and eighty-one mother newborn pairs (80 fetal growth restriction newborns, 101 normal newborns) participated in this study. The average PM10 exposure of each trimester and of the whole pregnancy was calculated using daily air pollution concentration data...

BACKGROUND: As an active component from traditional Chinese medicine, trigonelline has a protective effect on diabetes. This study evaluated the protective effects of trigonelline on diabetic mice during pregnancy. METHODS: Diabetes was induced in female mice by intraperitoneal injection for continuous 5-day of 40 mg/kg/day streptozotocin. Female mice were divided into 4 groups after they were allowed to mate with normal male mice: nondiabetic, nondiabetic treated with trigonelline (70 mg/kg) for 18 days, diabetic, and diabetic treated with trigonelline (70 mg/kg)...

Neonates born to transplanted mothers are exposed to immunosuppressive drugs during gestation and have a higher risk of being born prematurely and small for gestational age than the general population. We have prospectively followed up 27 children born to renal transplanted mothers from a single center and 31 healthy children born at term with adequate weight for gestational age. Comparisons of weight and length measurements were made at birth, 1 month (±0.9), 3 months (±1.0), 6 months (±1.0), 9 months (±1...

The degree of fetal growth restriction has been unclear in equine reproduction. In this study, 2,195 fetuses from 2,137 abortions during 11 seasons were examined to determine the causes of abortion, and fetal size dimensions (crown rump length and body weight) were measured. In total, 900 cases (42.1%) of abortion were identified as caused by viral infection (215, 10.1%), bacterial infection (156, 7.3%), fungal infection (25, 1.2%), circulation failure (406, 19.0%), multiple causes (66, 3.1%), deformity (13, 0...

Preeclampsia (PE) is involved in a group of obstetrical conditions closely related by the presence of placental dysfunction (PD), which also includes intrauterine growth restriction and placental abruption. The timely and accurate recognition and management of PE are often challenging because diagnostic criteria are still based on nonspecific signs and symptoms and because common severity criteria correlate poorly with adverse maternal and fetal outcomes. The discovery of the role of angiogenesis-related factors - soluble fms-like tyrosine kinase-1 (sFlt-1) and placental growth factor (PlGF) - in the underlying pathophysiology of PD has marked an important step for improving its early diagnosis and prognosis assessment before gestational week 34...

AIM: We designed a safety and dose-finding trial of tadalafil administered for fetal growth restriction (FGR). METHODS: Three cases were initially commenced on 10 mg/day and monitored for major adverse events. Should a major adverse event be observed in one or more of the three cases, an examination into its relation with tadalafil would be conducted by a safety evaluation committee. If one or more of these new cases exhibited the same adverse event, the trial would be stopped completely...
