One in five Medicare patients returns to the hospital after ‘observation stays’

June 20, 2017
As many as one in five older Medicare patients returns to the hospital after an observation stay, or short-term outpatient stay, a Yale-led study found.

Mammograms: Are we overdiagnosing small tumors?

June 7, 2017
An analysis of breast cancer data revealed that many small breast cancers have an excellent prognosis because they are inherently slow growing, according to Yale Cancer Center experts. Often, these cancers will not grow large enough to become significant within a patient’s lifetime and subsequently early detection could lead to overdiagnosis, said the reseachers.

In conversation: Joanna Radin on the ‘phenomenon’ of biobanking

June 7, 2017
When HIV/AIDS became a pandemic, epidemiologists wanted to know where it began. In the 1980s, they found their answer in a freezer filled with blood. This blood had been collected in the 1950s from members of indigenous communities in Africa as part of anthropological research on human variation. To this day, that sample is the oldest trace of HIV known to biomedicine. It is what launched Joanna Radin’s interest in the field of biobanking, a means of preserving blood and other tissues for future research.
