Top in endocrinology: Vaccine mandates in health care, thyroid function and brain perfusion

In a recent article, Jonathan D. Leffert, MD, spoke with a law expert about the legality of COVID-19 vaccine mandates for health care workers. It was the top story in endocrinology last week.

Another top story was about a correlation between abnormal free thyroxine levels and suboptimal cerebral blood perfusion in middle-aged and elderly adults. Both high and low thyroxine levels were found to have this effect, suggesting there is “an optimum free T4 level when considering treatment targets in hypothyroidism patients,” according to Oscar H. Roa Dueñas, MD.
