Attitudes toward prenatal diagnosis and termination of pregnancy in Saudi Arabia
… will soon make it possible to offer parents prenatal testing for a large number of different genetic disorders. The tests that have been offered to date are available because of technology, not because of the burden or prevalence of the condition. Parents' attitudes to different genetic …

Termination Rates Following Prenatal Diagnosis For Down Syndrome: A Systematic Review
… genetic cause of intellectual disability. Two prenatal testing approaches for Down syndrome are available: screening tests and diagnostic tests. Screening tests are non-invasive but are non-diagnostic and provide an estimate of the risk of an affected pregnancy. Even with recent improvements in …

I carry you in my heart : facing an incurable prenatal diagnosis
Prenatal diagnosis has given doctors the ability to predict problems before a child is even born. But what happens when the information gleaned from these tests is that the child is fatally sick? Doctors call these "futile" pregnancies. The increasing sophistication and prevalence of prenatal …

A comparison of attitudes towards prenatal diagnosis and pre-implantation genetic diagnosis
Technological advances in prenatal screening and diagnosis mean that it is now possible to test for a wide range of congenital conditions (Hewison et al., 2007). Traditionally testing has been carried out during pregnancy (prenatal diagnosis, PND). However, advances in technology have made it …

Attitudes to ward and Utilization of Non-Invasive Prenatal Testing For Chromosome Aneuploidy Among Ob/Gyns
<p>Prenatal diagnosis is traditionally made via invasive procedures such as amniocentesis and chorionic villus sampling (CVS). However, both procedures carry a risk of complications, including miscarriage. Many groups have spent years searching for a way to diagnose a chromosome aneuploidy without …

Next Generation Sequencing nell'analisi del DNA fetale da plasma materno per la diagnosi prenatale non invasiva di malattie genetiche
… common reasons that prompt couples to opt for prenatal diagnosis (PD). Unfortunately, current procedures of prenatal diagnosis are invasive and carry a 0.5-1% risk of fetal mortality. The discovery of fetal DNA in maternal plasma had opened new opportunities for non invasive diagnosis and to …

Sviluppo di una piattaforma per la diagnosi prenatale non invasiva di malattie genetiche in epoca gestazionale precoce
Prenatal diagnosis of aneuploidies and monogenic diseases is usually performed by amniocentesis or chorionic villous sampling. However, these procedures are associated with 0.5%-2% risk of miscarriage. The discovery of cell free fetal DNA (cffDNA) in maternal plasma in 1997 has provided a new …

Clinical implementation of first trimester combined test for aneuploidies in patients aged 35 years or older
… baby relates directly to maternal age. Invasive prenatal diagnosis based on advanced maternal age (AMA) alone is still a large contributor to invasive testing (amniocentesis and villocentesis). However, there are many reasons to abandon screening on the basis of AMA, given its low detection rate …

Diagnosi prenatale non invasiva di malattie monogeniche attraverso la ricerca e l'isolamento di cellule e DNA fetale nel sangue materno
Prenatal genetic diagnosis of monogenic diseases and chromosomal abnormalities is usually performed collecting fetal samples through villocentesis or amniocentesis. These invasive procedures are associated with 0.5-1% risk for the fetus. Due to it, in recent years, much effort has been made to …
