Researchers from Scotland have created a model to accurately predict for how long a woman treated with ovarian radiation can still become pregnant.
Researchers from Scotland have created a model to accurately predict for how long a woman treated with ovarian radiation can still become pregnant.
The researchers have calculated an effective sterilizing dose (ESD) of radiation for women aged 0 to 50 years. They determined that the ESD, or the dose of fractionated radiotherapy (Gy) at which premature ovarian failure occurs immediately after treatment in 97.5% of women, decreases with increasing age at treatment, so that ESD at birth is 20.3 Gy, at 10 years is 18.4 Gy, at 20 years is 16.5 Gy, and at 30 years is 14.3 Gy.
Using these calculations, they were able to determine, for example, that a 10-year-old girl receiving 3 Gy ovarian radiation has a mean of about 27 years before ovarian failure, a 20-year-old woman receiving 6 Gy has a mean of about 11 years until sterility, and a 30-year-old woman receiving 9 Gy has a mean time till ovarian failure of about 3 years.
Link between prenatal air pollution and reduced lung function in offspring reported
July 25th 2024Higher prenatal exposure to PM2.5 pollution is associated with reduced lung volume and airflow limitation in children, highlighting the critical impact of air pollution on in utero lung development.

Cut costs observed from out-of-home care in children with prenatal substance exposure
July 24th 2024A recent study reveals that while children exposed to maternal substance use face higher hospital costs up to age 20 years, out-of-home care significantly mitigates this financial burden.
