Chris Kresser:  I think that’s like the biggest change we’re going to see, is the nature of this device will change people’s awareness of health, and that’s incredible to think about.  There are so many people who are interested in tech that aren’t necessarily that interested in health.  But due to their interest in tech, they’re going to become interested in health, just because that’s going to be one of the main implementations of the iWatch.  And as you said, there’s going to be such a big community of people developing software.  And what we notice and pay attention to is what we can change.  If we’re not aware of something, we can’t change it.  And that, to me, is the most exciting factor of this new technology. It’s really going to dramatically increase people’s awareness of things—like how many steps they’re taking, and what kind of food they’re eating, and if they’re tracking that, and their heart rate, and how their heart rate variability might correlate to what type of exercise they should be doing that day.  And it’s not just about those kind of specific things that they’re becoming aware of.  It’s that focusing even on a few specific things like that is inevitably going to expand their awareness around all aspects of their health.  So I think it can really be a revolutionary impact.  And I know, as a clinician too, I’m really looking forward to having additional ways that I can both support my patients, by referring them to apps and things that can make implementing some of the recommendations that I give them easier and more practical.  But if I need to collect data for something, some of these devices are going to make that a lot easier and they’re going to be able to send it back to me in a way that’s very actionable for me as a clinician.  It’s a pretty exciting time to be involved in medicine and particularly the evolution of medicine.

The Nightingale model was widely copied. Linda Richards (1841–1930) studied in London and became the first professionally trained American nurse. She established nursing training programs in the United States and Japan, and created the first system for keeping individual medical records for hospitalized patients.[121] The Russian Orthodox Church sponsored seven orders of nursing sisters in the late 19th century. They ran hospitals, clinics, almshouses, pharmacies, and shelters as well as training schools for nurses. In the Soviet era (1917–1991), with the aristocratic sponsors gone, nursing became a low-prestige occupation based in poorly maintained hospitals.[122]
The development of modern neurology began in the 16th century in Italy and France with Niccolò Massa, Jean Fernel, Jacques Dubois and Andreas Vesalius. Vesalius described in detail the anatomy of the brain and other organs; he had little knowledge of the brain's function, thinking that it resided mainly in the ventricles. Over his lifetime he corrected over 200 of Galen's mistakes. Understanding of medical sciences and diagnosis improved, but with little direct benefit to health care. Few effective drugs existed, beyond opium and quinine. Folklore cures and potentially poisonous metal-based compounds were popular treatments. Independently from Ibn al-Nafis, Michael Servetus rediscovered the pulmonary circulation, but this discovery did not reach the public because it was written down for the first time in the "Manuscript of Paris"[79] in 1546, and later published in the theological work which he paid with his life in 1553. Later this was perfected by Renaldus Columbus and Andrea Cesalpino. Later William Harvey correctly described the circulatory system. The most useful tomes in medicine used both by students and expert physicians were De Materia Medica and Pharmacopoeia.
In the 17th century medicine was helped by the microscope (invented at the end of the 16th century). Then in 1665 Robert Hooke was the first person to describe cells in his book Micrographia. Finally in 1683 Antonie van Leeuwenhoek observed microorganisms. However he did not realise they caused disease. Meanwhile in 1661 Robert Boyle published the Skeptical Chemist, which laid the foundations of modern chemistry. In the early 17th century doctors also discovered how to treat malaria with bark from the cinchona tree (it contains quinine).
Medicine made huge advances in the 20th century. The first non-direct blood transfusion was made in 1914. Insulin was first used to treat a patient in 1922. The EEG machine was first used in 1929. Meanwhile many new drugs were developed. In 1910 the discovered salvarsan, a drug used to treat syphilis was discovered. In 1935 prontosil was used to treat blood poisoning. Later it was discovered that the active ingredient of the dye was a chemical called sulphonamide, which was derived from coal tar. As a result in the late 1930s a range of drugs derived from sulphonamide were developed.

From 1917 to 1923, the American Red Cross moved into Europe with a battery of long-term child health projects. It built and operated hospitals and clinics, and organized antituberculosis and antityphus campaigns. A high priority involved child health programs such as clinics, better baby shows, playgrounds, fresh air camps, and courses for women on infant hygiene. Hundreds of U.S. doctors, nurses, and welfare professionals administered these programs, which aimed to reform the health of European youth and to reshape European public health and welfare along American lines.[174]

This week’s podcast features: Daniel Schmachtenburger, co-founder and director of research and development at Neurohacker Collective, in Complexity Medicine: The Basis for a Functional Standard of Care. Daniel is a deep thinker and researcher on how human regulatory systems function, how they break down and how they can be supported to function with greater resilience.

After 1871 Berlin, the capital of the new German Empire, became a leading center for medical research. Robert Koch (1843–1910) was a representative leader. He became famous for isolating Bacillus anthracis (1877), the Tuberculosis bacillus (1882) and Vibrio cholerae (1883) and for his development of Koch's postulates. He was awarded the Nobel Prize in Physiology or Medicine in 1905 for his tuberculosis findings. Koch is one of the founders of microbiology, inspiring such major figures as Paul Ehrlich and Gerhard Domagk.[127]
The Section of the History of Medicine is a freestanding unit in the Yale University School of Medicine engaged with research and teaching in the history of medicine, the life sciences, and public health. In addition to instruction for medical students, including mentoring M.D. theses, the faculty collaborates with colleagues in the History Department, in the Program in the History of Science and Medicine, which offers graduate programs leading to the M.A., Ph.D., and combined M.D./Ph.D. degrees and an undergraduate major in the History of Science/History of Medicine. The Section contributes to the Program's colloquia, and Distinguished Annual Lectures, workshops, and symposia in medical history. Through research and teaching, the faculty seeks to understand medical ideas, practices, and institutions in their broad social and cultural contexts, and to provide intellectual tools to engage with the challenges faced by contemporary medicine.
^ England and Wales had nine county and borough asylums in 1827 with an average capacity of a little over 100 patients, but by 1890 there were 66 such asylums containing on average 800 patients each;[182] the total number of patients so confined increased from 1,027 in 1827 to 74,004 in 1900.[183] Similarly, in Germany, between 1852 and 1898 the asylum population increased seven-fold from 11,622 to 74,087 patients during a period when the total population had only grown by ten per cent.[158] In America the asylum population had risen to almost 250,000 on the eve of the First World War.[184]
A major scourge of the 18th century was smallpox. However in the 18th century people realized that milkmaids who caught cowpox were immune to smallpox. In 1796 Edward Jenner introduced vaccination. (Its name is derived from the Latin word for cow, Vacca). The patient was cut then matter from a cowpox pustule was introduced. The patient gained immunity to smallpox. (Jenner was not the first person to think of this but it was due to his work that it became a common practice). Unfortunately nobody knew how vaccination worked.
This week, we feature the keynote presentation from the summit by Dr. Jeffrey Bland. You can get this talk and many other gifts by registering for the summit. In his talk, Dr. Jeffrey Bland shares his view of the current state of genetics. Even If you're not interested in genetic testing, we hope that you will take a few minutes and listen to the godfather of functional medicine, as he shares his thoughts on genomics and why it will be the catalyst for functional medicine to become the operating system for a new era of predictive preventative medicine.

When the Roman Empire split into the Western and Eastern Empires, the Western Empire, centered on Rome, went into a deep decline and the art of medicine slowly slipped away, with the physicians becoming pale shadows of their illustrious predecessors and generally causing more harm than good. Western Europe would not appear again in the history of medicine until long after the decline of Islam.
The Romans were also skilled engineers and they created a system of public health. The Romans noticed that people who lived near swamps often died of malaria. They did not know that mosquitoes in the swamps carried disease but they drained the swamps anyway. The Romans also knew that dirt encourages disease and they appreciated the importance of cleanliness. They built aqueducts to bring clean water into towns. They also knew that sewage encourages disease. The Romans built public lavatories in their towns. Streams running underneath them carried away sewage.
Ancient Egypt developed a large, varied and fruitful medical tradition. Herodotus described the Egyptians as "the healthiest of all men, next to the Libyans",[18] because of the dry climate and the notable public health system that they possessed. According to him, "the practice of medicine is so specialized among them that each physician is a healer of one disease and no more." Although Egyptian medicine, to a considerable extent, dealt with the supernatural,[19] it eventually developed a practical use in the fields of anatomy, public health, and clinical diagnostics.
I ended up selling the practice to my partner and taking a 20-month sabbatical due to a motor vehicle accident. I had considered retiring after selling the practice, but in the area where I live there are very few people practicing this style of medicine and the need far exceeds the number of people who have the skills or knowledge. During the time I was not working, I had many former patients contacting me and wanting to know when I was going to open a new practice.
