Rohan D'Souza, Prakesh S Shah, Beate Sander
Clinical decision-making in perinatology involves tradeoffs between two intricately related individuals - mother and fetus. Decision-making in perinatology is challenging due to competing interests of the mother and the fetus. Although decision analytic methods are increasingly used to develop processes for clinical and cost-effectiveness analyses in perinatology, there are no guidelines on the conduct and reporting of decision analysis studies that takes into account the complexities of the mother-fetus dyad...

Introduction: Though the human fetus is exposed to placentally derived human chorionic gonadotropin (hCG) throughout gestation, the role of hCG on the fetal brain is unknown. Review of the available literature appears to indicate that groups of women with higher mean levels of hCG during pregnancy tend to have offspring with lower cerebral palsy (CP) risk. Given that newborn cerebral injury often precedes the development of CP, we aimed to determine whether hCG may protect against the neurodegenerative effects of neonatal brain injury...

Ataxia-telangiectasia (A-T), or Louis-Bar syndrome, is a rare neurodegenerative disorder associated with immunodeficiency. For families with at least one affected child, timely A-T genotyping during any subsequent pregnancy allows the parents to make an informed decision about whether to continue to term when the fetus is affected. Mutations in the ATM gene, which is 150 kb long, give rise to A-T; more than 600 pathogenic variants in ATM have been characterized since 1990 and new mutations continue to be discovered annually...

Intra-amniotic (IA) lipopolysaccharide (LPS) injection in sheep induces inflammation in the fetus. Human amnion epithelial cells (hAECs) moderate the effect of IA LPS on fetal development, but their influence on the acute inflammatory response to IA LPS is unknown. We aimed to determine the effects of hAECs on the acute fetal inflammatory response to IA LPS. After surgical instrumentation at 116 days' gestation (d) ewes were randomized to 1 of 4 groups at 123 d: IA LPS (10 mg) and intravenous (IV) saline (n = 8), IA LPS and IV hAECs (n = 6), IA saline and IV saline (n = 5) or IA saline and IV hAECs (n = 5)...

Background: Present study carried out in a tertiary referral hospital in South India attempts to determine the predictive value of integrated screening at 11-14-week antenatal visit. Objectives: To determine the detection rate of fetal abnormalities at 11-14 weeks and also to predict the placental dysfunction disorders based on early integrated evaluation. Method: Integrated screening performed on 440 women between 11 and 14 weeks, including detailed maternal history [medical history, bad obstetric history (BOH)], body mass index (BMI), mean arterial pressure (MAP), detailed ultrasound and maternal serum biochemistry as part of combined first-trimester screening for aneuploidy...

BACKGROUND: Cancer treatment during pregnancy is a growing problem especially now that women delay childbearing. Systemic treatment of these malignancies during pregnancy centers mainly on the anticancer drugs anthracyclines, widely used in treating hematological and breast cancer during pregnancy and sometimes associated with early and late toxicity for the fetus. Owing to concern about their cardiac and neurodevelopmental toxicity more information is needed on which anthracycline to prefer and whether they can safely guarantee a cardiotoxicity-free outcome in the fetus...

The objective was to evaluate the histomorphometric characteristics of the testis and ovaries of pig fetuses at different gestational ages, as well as their correlation with some fetus measurements. Forty-four fetuses were separated for gender (male and female) and gestational age (50, 80 and 106days of gestation). After slaughter, fetuses had their body length, head and thoracic perimeters measured and their gonads submitted to histomorphometric analyses. The gonadal characteristics at different gestational ages were statistically compared, correlations with the fetal measurements were performed and equations to predict the gonadal characteristics from the fetal measurements were obtained...

Context: Fetal overexposure to glucocorticoids in utero is associated with fetal growth restriction and is postulated to be a key mechanism linking suboptimal fetal growth with cardiovascular disease in later life. Objective: To develop a model to predict maternal-fetal glucocorticoid transfer. We hypothesised placental 11β-HSD2 would be the major rate-limiting step in maternal cortisol transfer to the fetus. Design: We used a deuterated cortisol tracer in the ex vivo placental perfusion model, in combination with computational modelling, to investigate the role of interconversion of cortisol and its inactive metabolite cortisone on transfer of cortisol from mother to fetus...

Attention-deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by hyperactivity, impulsivity, and/or inattention. Women with ADHD represent a particularly vulnerable group, given their increased risk for psychosocial and parenting difficulties. Women's health care clinicians should expect to encounter women with diagnosed and undiagnosed ADHD that may or may not be treated. Pharmacologic intervention, namely, prescription stimulants, is an important consideration for pregnant and breastfeeding women with ADHD, especially because the US Food and Drug Administration has determined that there is not enough information to confirm either harm or lack of harm to the developing fetus following exposure to these drugs...

BACKGROUND: Preclinical evidence suggests that general anesthetics can dose dependently induce neurodegeneration in the developing brains of animals which can be reliably determined by measurement of blood S100β, but this correlation remains unclear in humans. We hypothesized that S100β would not be increased in cord arterial blood of fetuses exposed briefly to general anesthetics during a C-section, compared with epidural anesthesia. METHODS: A prospective observational clinical study comparatively measured changes of brain damage biomarker S100β ratio of umbilical artery over vein (changes after fetus circulation) immediately after delivery under C-section with either epidural or general anesthesia...

Obesity is one of the major health problems and a determining factor in the prevalence of diseases such as metabolic syndrome, asthma, sleep apnea, infertility and various types of cancer. Its origin is multifactorial, involving genetic, socioeconomic and environmental factors. These last ones contribute mostly to explain the current epidemic growth of this disease. The sedentary lifestyle, inadequate diet, lack of sleep, alterations in intestinal microbiota and stress are factors related to its development...

High-frequency ultrasonography (HFUS) is a common method to non-invasively monitor the real-time development of the human fetus in utero. The mouse is routinely used as an in vivo model to study embryo implantation and pregnancy progression. Unfortunately, such murine studies require pregnancy interruption to enable follow-up phenotypic analysis. To address this issue, we used three-dimensional (3-D) reconstruction of HFUS imaging data for early detection and characterization of murine embryo implantation sites and their individual developmental progression in utero...

Pregnancy is one of the defining characteristics of placental mammals. Key in the growth and development of the fetus during pregnancy are the dynamics of glucocorticoids (GCs) and their binding protein - corticosteroid-binding globulin (CBG), which determines how much of the GCs are free and biologically active. Out of more than 5,000 species of placental mammals in 19 different orders, our understanding of the dynamics of maternal GCs and CBG during pregnancy is largely limited to the detailed study of 3 groups - sheep, laboratory rodents, and humans...

Vinpocetine is being used worldwide by people of all ages, including pregnant women, for its purported multiple health benefits. However, limited data is available addressing the safety/toxicity of vinpocetine. The National Toxicology Program conducted studies to examine potential effects of vinpocetine on the developing rat. Disposition data is helpful to put the fetal findings into context and provide information on the potential risk for humans. The current study reports the systemic exposure and toxicokinetic (TK) parameters of vinpocetine and metabolite, apovincaminic acid (AVA), in pregnant Harlan Sprague Dawley rats, fetuses and amniotic fluid following oral gavage exposure of dams to 5 and 20mg/kg vinpocetine from gestational day 6 to 18...

INTRODUCTION: Regionalization of perinatal care has been developed to improve the survival of preterm babies. The mortality rate is higher among very premature infants born outside level-3 maternity units. The objective of this study was to evaluate the preventability of these very premature births occurring outside recommendations within level-2B maternity units. The secondary objective was to describe the care of premature infants between 23 and 24 weeks. METHODS: This is a single-center retrospective qualitative study of the care delivery pathways...

BACKGROUND: The placenta plays an important role during pregnancy providing maternal blood supply from the uterus to the developing fetus. The structure and function of the placenta changes with gestation, as the fetus develops and its demands change. This study aims to elucidate changes in cytokine and chemokine gene expression throughout mid-to-late gestation in rat placenta. METHODS: Sprague Dawley rats were time-mated, and placentae were obtained from 6 pregnant dams at 4 different gestational periods: E14...

This study was made on 24 camel fetuses of crown-rump vertebral length (CVRL) ranging from 10.5 cm to 105 cm CVRL (94-352 days old). These camel fetuses were classified into three groups representing the three trimesters of prenatal life. During the first trimester (94-142 days), lingual papillae (circumvallate and lentiform papillae) were demonstrated on the lingual root, but lingual body and the apex were almost free of papillae except for some scattered epithelial projections especially near the lateral borders of the body...

Background and aims: Selective serotonin reuptake inhibitors (SSRIs) are antidepressants increasingly prescribed against depression during and after pregnancy. However, these compounds cross the placenta and are found in breast milk, thus reaching, and possibly affecting, the fetus and infant during critical developmental stages. Fluoxetine (FLX), a widely used SSRI, can interfere with estrogen signaling, which is important for the development of female sex organs and certain brain areas, among others...

Methylmercury (MeHg) is a neurotoxicant known to affect the developing fetal brain as a sensitive target organ. As most mercury (Hg) in blood is MeHg, total mercury (THg) levels in blood are used to estimate the body burden of MeHg. The nutrients selenium (Se), vitamin E, and docosahexaenoic acid (DHA) are protective against MeHg toxicity. We compared maternal and cord blood concentrations of biochemical substances, THg and Se, vitamin E, DHA, and other elements, fatty acids, and amino acids in 54 Japanese mother-newborn pairs to elucidate the fetal risk of MeHg toxicity...

NMOSD develops primarily in women of childbearing age, and several previous studies have shown that the disorder may increase the risk of miscarriage. However, there are no reports, to our knowledge, of fetal malformation, other than neonatal hydrocephalus, related to NMOSD. We report a 30-year-old woman who experienced recurrent neuritis and who was seropositive for AQP4-IgG. She became pregnant, and the fetus was found to have ectrodactyly. Histological analysis of the placenta showed moderate inflammatory infiltration; however, whether fetal malformation in NMOSD is related to inflammation and AQP4-IgG remains to be determined...
