Prenatal ethanol (EtOH) exposure is known to induce adverse effects on fetal brain development. Docosahexaenoic acid (DHA) has been shown to alleviate these effects by upregulating antioxidant mechanisms in the brain. The liver is the first organ to receive enriched blood after placental transport; therefore, it could be negatively affected by EtOH, but no studies have assessed the effects of DHA on fetal liver.

SummaryFibroblast growth factor (FGF) signalling acts as one of modulators that control neural crest cell (NCC) migration, but how this is achieved is still unclear. In this study, we investigated the effects of FGF signalling on NCC migration by blocking this process. Constructs that were capable of inducing Sprouty2 (Spry2) or dominant-negative FGFR1 (Dn-FGFR1) expression were transfected into the cells making up the neural tubes. Read More

Smoking is frequently presented as being particularly problematic when the smoker is a pregnant woman because of the potential harm to the future child. This premise is used to justify targeting pregnant women with a unique approach to smoking cessation including policies such as the routine testing of all pregnant women for carbon monoxide at every antenatal appointment. This paper examines the evidence that such policies are justified by the aim of harm prevention and argues that targeting pregnant women in this way is likely to do more harm than good. Read More

Measurement of cell-free fetal DNA (cffDNA) is an indispensable process for non-invasive prenatal screening (NIPS). According to recent studies, cffDNA in maternal plasma can be enriched for various lengths of fragments, and a sufficient amount of cffDNA can effectively eliminate background interference on the part of maternal DNA. Therefore, we developed a simple and effective separation method, improved NIPS (iNIPS), that enriches the fetal fraction and improves the accuracy of NIPS for fetal aneuploid detection. Read More

The etiology of pulmonary vascular abnormalities in CDH is incompletely understood. Studies have demonstrated improvement in pulmonary vasculature with prenatal therapy in animal models. We hypothesize that prenatal sildenafil may attenuate defective pulmonary vascular development via modulation of vSMC phenotype from undifferentiated, proliferative phenotype to differentiated, contractile phenotype.

Spina bifida aperta is a relatively common congenital defect that occurs in the general population. Once the disorder has been diagnosed, a discussion, that can be emotionally-charged, ensues about whether to treat it prenatally or to only offer surgery postnatally. Given that there are good arguments for and against both options, it is of paramount importance to gain a good understanding of the major advantages and disadvantages of the various surgical approaches.

Whole-exome sequencing (WES) has been used as a standard of care for postnatal diagnosis in the clinical setting in the past few years for children and adults with undiagnosed disease. Many rare disorders have been diagnosed through WES, which is less expensive than the traditional serial genetic testing where patients had previously spent years on an uninformative diagnostic odyssey. Seeking a diagnosis often entails enduring time consuming, and sometimes invasive procedures which may be associated with medical risks that are stressful for families and impose a heavy burden on the health-care system.

Autosomal chromosome aneuploid pregnancies that survive to term, namely, trisomies 13, 18, and 21, account for 89% of chromosome abnormalities with a severe phenotype identified in prenatal samples. They are traditionally detected by full karyotype analysis of cultured cells. The average reporting time for a prenatal karyotype analysis is approximately 14 days, and in recent years, there has been increasing demand for more rapid prenatal results with respect to the common chromosome aneuploidies, to relieve maternal anxiety and facilitate options in pregnancy.

A prenatal noninvasive genetic screening test that yields a positive result typically warrants further direct assessment of fetal DNA following an invasive procedure. The precious nature of these invasively acquired samples, combined with the time sensitive nature with which results should be reported, demands that the methodologies used for analysis be quick, efficient, and dependable.Prenatal diagnosis has been performed using DNA extracted from amniotic fluid and chorionic villi for several decades, and more recently methodologies have been developed to extract cell free fetal DNA from amniotic fluid.

In the nearly 60 years since prenatal diagnosis for genetic disease was first offered, the field of prenatal diagnosis has progressed far past rudimentary uterine puncture to provide fetal material to assess gender and interpret risk. Concurrent with the improvements in invasive fetal sampling came technological advances in cytogenetics and molecular biology that widened both the scope of genetic disorders that could be diagnosed and also the resolution at which the human genome could be interrogated. Nowadays, routine blood work available to all pregnant women can determine the risk for common chromosome abnormalities; chorionic villus sampling (CVS) and amniocentesis can be used to diagnose nearly all conditions with a known genetic cause; and the genome and/or exome of a fetus with multiple anomalies can be sequenced in an attempt to determine the underlying etiology.
