Dr. Shameka Poetry Thomas is a medical sociologist with special interest in reproductive justice and genetics technology as well as the intersection of maternal healthcare with sickle cell disease. After receiving her Ph.D. from the University of Miami, she completed her two-year postdoctoral fellowship at the National Institutes of Health (NIH)/National Human Genomics Research Institutes (NHGRI).In this episode, Dr. Thomas centers the experiences of pregnant Black women with sickle cell disease, who, despite advances in medicine, genetics and reproductive technology, have been neglected by research communities due to intersecting marginalized identities despite high mortality during pregnancy and childbirth. Dr. Thomas walks us through what non-invasive prenatal testing (NIPT) is and how it relates to sickle cell disease specifically. Her work comes to life by illustrating the converging effects of colonialism, racism, bias and stigmatization through moving real-world stories. Her research sheds light on the lived experiences of patients who are left to integrate complex information from multiple specialists to interpret meanings for themselves, their families, their finances and their communities in the setting of collective and individual trauma. She describes the importance of using qualitative research methods to explore a range of experiences within groups rather than treating groups as a monolith. She also acknowledges the heaviness of this type of qualitative work and the importance of dissemination of findings to spark action.Dr. Thomas connected the long history of research abuses in the US to current-day research practices that continue to disrespect Black women. For example, recent sickle cell disease NIPT research was conducted without incorporating the unique lived experiences of the affected women to understand whether and how to incorporate these technologies into practice. She emphasized the urgent need for the development and implementation of more comprehensive ethical guidelines in the field of reproductive health. These guidelines should specifically address the ethical dimensions of research on sickle cell disease and the burgeoning field of genetic technology, ensuring that the rights, dignity, and well-being of those affected particularly within marginalized communities. Finally, Dr. Thomas called for more robust advocacy efforts aimed at amplifying the voices of Black women and other marginalized groups in the creation of healthcare policies and research priorities. Such advocacy must not only challenge existing inequities but also ensure that affected communities have the power and agency to influence decisions that impact their lives, fostering a healthcare system that is equitable, inclusive, and just.Read Dr. Thomas's work here:Thomas SP, Fletcher FE, Willard R, Ranson TM, Bonham VL.

In this episode, our hosts review how the screening for Down syndrome and other chromosome abnormalities has changed over the last few decades. They go in depth about the latest technology such as SNP*-based technology tests which deliver the most accurate non-invasive prenatal testing available. This is often referred to as (Non-invasive perinatal testing) NIPT or (Non-invasive perinatal screening) NIPS. As always, we'd love to hear from you!

Chelsea Castonguay is a mother with a 3 year old son who has Klinefelter syndrome. Noah was diagnosed in utero after Chelsea felt like something was off around 13 weeks and requested Noninvasive Prenatal Testing. Chelsea talks about how she was devastated learning her son would have Klinefelter syndrome 47 XXY. After Noah was born she talks about how they were fearful about telling family. At a visit with a specialist, they were told to "never tell their son he had XXY". Confused about what they were told Chelsea talks about how this consultation lead to their decision to overcome fear and open up about Noahs diagnosis. Opening up created a network of support they never had. Chelsea said she doesn't want anyone to feel alone and wants to support others just like those who supported her.
In this episode, we discuss the latest guidance about screening for fetal abnormalities with cell-free DNA testing, the COVID 19 vaccine for breastfeeding and lactating women, and some true and not so true ways to determine fetal gender.
Non-invasive prenatal testing based on cell-free DNA is now a widely used technique. However, quality control materials that have properties identical to clinical samples and that are applicable to a wide range of procedures are not available to support assay development, internal or external quality control, and proficiency testing. The June 2019 issue of Clinical Chemistry includes a study describing the development of such quality control materials that comprise simulated human plasma and mixtures of mother cell line derived cell-free DNA based on DNA fragmentation factor digestion.
Researchers have developed approaches for the noninvasive prenatal testing of single gene diseases.

Interview with Diana W. Bianchi, MD, author of Noninvasive Prenatal Testing and Incidental Detection of Occult Maternal Malignancies
Prenatal testing using blood specimens rather than more invasive sampling has been successfully used for common chromosome disorders and for clinically significant copy number variations . H owever , detecting single gene disorders which are caused by mutations remains an analytical challenge.
