A UC San Francisco-led study found that delivering medicine for spinal muscular atrophy (SMA) via the amniotic fluid was safe and helped prevent damage to nerve cells. The therapy used molecules called antisense oligonucleotides (ASOs), which can alter gene expression, and was tested in mice and sheep with promising results.
A study found that clinicians are more likely to recommend invasive prenatal tests like amniocentesis for mothers who conceived naturally, compared to those who used assisted reproductive technologies (ART). The 'precious baby' phenomenon may affect medical advice, with doctors being influenced by the method of conception.
The Amniochip technology uses microarray technology to detect genetic syndromes with a diagnostic resolution 100 times greater than conventional techniques. This reduces the waiting time for results to 48 hours, compared to three weeks with traditional methods.
Researchers have developed a simple, non-invasive blood test that can detect chromosomal abnormalities in the developing fetus using molecular genetic probes. The test has already shown promise in identifying DNA from the Y chromosome and is being investigated for detecting trisomy 21 (Down's syndrome) and other conditions.
A study of over 64,000 pregnant women found that larger hospital units with more experience had lower miscarriage rates after amniocentesis and chorionic villus sampling. The research suggests that the number of procedures carried out by a department affects miscarriage rates.
Researchers at Howard Hughes Medical Institute have created a non-invasive blood test that accurately detects Down syndrome and two other serious chromosomal defects. The test is more accurate than previous methods and can provide results within a few days, reducing the wait time for anxious parents.
A new study published in the journal Obstetrics & Gynecology found that midtrimester amniocentesis is associated with a lower risk of miscarriage than previously reported, with a rate of approximately 1 in 1,600 pregnancies. The study refutes the typically quoted 0.5% pregnancy loss rate and suggests it may be even lower than 0.1%.
Researchers found that both amniocentesis and chorionic villus sampling (CVS) carry a low risk of miscarriage. While CVS was initially believed to have a higher rate of miscarriage, the study revealed that this risk decreased over time.
A study published in The Lancet suggests that prenatal genetic testing should be offered to all pregnant women, regardless of age or risk, as it is cost-effective. The researchers found that the benefits of early testing outweigh the costs, particularly for high-risk pregnancies.
