Proud to share this @JCO_ASCO paper written w/Rick Kodish & @JonMarronMD . We define *cancer exceptionalism​​*, which may inappropriately influence shared decision-making. Patient values/preferences drive #SDM, but might clinicians’ values limit choices? https://t.co/aTWV482AOS

@SocDoneLeft @SashaGusevPosts Worth also stating that some quite effective embryo selection has no need for advanced techniques like GWAS. Chromosomal disorders and heritable single-gene disorders have been assessed for several decades via “old fashioned” technology like karyotyping, PCR, etc

This NYT piece by @snolen is excellent but appalling

Whether this is a "cost-cutting measure" or not aligned w/ the Trump admin's "priorities" or an instance of growing US isolationism, ending (or even just ⬇️ing) intl vax funding is awful & short-sighted
