With a history spanning at least years, bloodletting has only recently—in the late 19th century—been discredited as a treatment for most ailments. The practice of bloodletting began around years ago with the Egyptians, then continued with the Greeks and Romans, the Arabs and Asians, then spread through Europe during the Middle Ages and the Renaissance. It reached its peak in Europe in the 19th century but subsequently declined and today in Western medicine is used only for a few select conditions.
HFEa major regulator of iron Fe homeostasis, has been suggested to be under positive selection in both European and Asian populations. While the genetic variant under selection in Europeans a non-synonymous mutation, CY has been relatively well-studied, the adaptive variant in Asians and its functional consequences are still unknown. Identifying the adaptive HFE variants in Asians will not only elucidate the evolutionary history and the genetic basis of population difference in Fe status, but also assist the future practice of genome-informed dietary recommendation.
We prospectively assessed 99 Southeast Asians for the presence of thyroid disease who were attending a primary care clinic devoted to the care of refugees. Subjects were undergoing evaluation as new patients and had no previously diagnosed thyroid abnormality. Each patient had a physical examination performed by his or her primary-care provider, was given a standardized questionnaire that focused on symptoms of thyroid disease and underwent a venipuncture for total thyroxine, triiodothyronine resin uptake and thyrotropin TSH concentration. Those who had an abnormal examination, calculated free thyroxine index FT4I or TSH level were re-examined by an endocrinologist and had repeat thyroid studies performed.
