Atherosclerosis in Ancient Mummies Revisited

By -
Many of you are already aware of the recent study that examined atherosclerosis in 137 ancient mummies from four different cultures (1).  Investigators used computed tomography (CT; a form of X-ray) to examine artery calcification in mummies from ancient Egypt, Peru, Puebloans, and arctic Unangan hunter-gatherers.  Artery calcification is the accumulation of calcium in the vessel wall, and it is a marker of severe atherosclerosis.  Where there is calcification, the artery wall is thickened and extensively damaged.  Not surprisingly, this is a risk factor for heart attack.  Pockets of calcification are typical as people age.

I'm not going to re-hash the paper in detail because that has been done elsewhere.  However, I do want to make a few key points about the study and its interpretation.  First, all groups had atherosclerosis to a similar degree, and it increased with advancing age.  This suggests that atherosclerosis may be part of the human condition, and not a modern disease.  Although it's interesting to have this confirmed in ancient mummies, we already knew this from cardiac autopsy data in a variety of non-industrial cultures (2, 3, 4, 5).

Feedback in Three Steps

By -
© 2003, Coert Visser As a manager you have just led a meeting. John brought forward a proposal to implement a Customer Relationship Management (CRM) system. He did this convincingly and enthusiastically but seemed to leave very little room for his colleagues Michael and Peter to respond. You want to talk to John about this...but how? Feedback is essential Giving and getting feedback is essential. The fact is, no matter how hard we try, we don’t always automatically perform excellent. We need information from others to know what is expected from us, how others perceive us, what we do well and what we should do better. Sometimes others have more expertise or skills, they look at your behavior from a different angle, and they may have access to different information. When feedback functions well in an organization, people are interested in signals about the effects of their behavior and they constructively correct each other. Fantastic! But now the less rosy daily practice.….. Feedback ca...

Esoteric Aspects of Edgar Cayce's Life

Gladys Davis, Hugh Lynn Cayce (right) and Harmon Hartzell Bro were among the members of this A Search for God study group meeting at A.R.E. Headquarters at Lake Holly in 1950.  This photo is from Edgar Cayce's Photographic Legacy (1978) compiled by David M. Leary. Some of Edgar Cayce's psychic (channeled) readings diagnosed and prescribed for people's physical ailments and disturbances.  These were described by Thomas Sugrue in There Is A River (1942) as presenting "cases, hundreds and hundreds of them, wherein the treatments have been faithfully followed, and the predicted results have been achieved." When information that was sought wasn't successfully forthcoming (such as locations for lost treasure or oil wells), Cayce and his associates were baffled.  These circumstances are chronicled in the book The Outer Limits of Edgar Cayce's Power (1971) by Edgar's sons Edgar Evans Cayce and Hugh Lynn Cayce.  One chapter, "Readings for...

Case Profile: Edgar Cayce

By -

Edgar Cayce (1877-1945) became known as an American mystic and "psychic diagnostician" healer following hypnotic sessions where he would go into a trance and his body would be used as a channel.   The communicating Intelligence would speak in plurality, usually beginning a 'reading' with a statement such as "We have the body . . ." and finishing upon saying "We are through for the present."  I first learned about Cayce through reading Jess Stearn's biographies Edgar Cayce — The Sleeping Prophet (1967) and A Prophet in His Own Country — The Story of the Young Edgar Cayce (1974).  The first biography to be written about Cayce is There Is a River: The Story of Edgar Cayce (1943) by Thomas Sugrue, whose book heightened public understanding about Cayce during the final years of his life.  Sidney Kirkpatrick's Edgar Cayce: An American Prophet was published in 2000. Since 2005, I've occasionally studied portions of the extant 14,306 Cayce...
