The Microbiota Vault
In January, I moderated a symposium that was based (virtually) in Peru to discuss preserving both the culture and the microbes of its indigenous people. Similar events, organized by the Global Microbiome Network, are planned in other regions around the world where indigenous populations still exist. Why is this important?
I’ve written before (here and here) about the importance of a healthy microbiota – those trillions of microbes that live in and on our bodies, especially in the gut. The collection of genes inside these microbial cells in called the microbiome. There are more genes in the microbiome than there are genes in the human body. These microbial genes perform necessary functions in our bodies like helping to digest food and producing vitamins. If some of these microbes die off, the functions performed by their genes are also lost. The loss of microbial species in our guts appears to be playing a role in the rise in chronic diseases that we are seeing in industrialized society. More and more research studies confirm the role of the microbiome in health and disease.
Using art to heal
Because Health is Life, our lifestyles are just as important to our health as going to the doctor or taking our medicines. In a paper published June 30, 2015 in the Annals of Internal Medicine, a study looking at survey data found that half the heart disease deaths in the US from 2009-2010 were caused by 5 factors all of which can be modified through healthy behavior: smoking, obesity, high cholesterol, diabetes and high blood pressure. But many of these behaviors are difficult to change and are influenced by our families, our culture and our community.
This picture shows that clinical care by doctors and hospitals accounts for only about 20% of health outcomes. The picture comes from a project called County Health Rankings developed by the University of Wisconsin Population Health Institute (and supported by the Robert Wood Johnson Foundation) that looks at health by county in the US. Addressing factors like cigarette smoking, income, education, employment, housing and clear air can help make communities healthier places to live.
We need to find ways to build healthier communities and the arts may be one way to accomplish this.
FODMAPs
A few weeks ago, I was asked if I knew anything about the low FODMAP diet as a treatment for inflammatory bowel disease (IBD). I was sure this was yet another fad diet (or that the name was misspelled – seemed like FOD should be FOOD, right?) .
Imagine my surprise when I found detailed information about the diet and its use in treating irritable bowel syndrome (IBS) on the Stanford Health Care website. Irritable bowel syndrome is a chronic condition that causes abdominal pain, bloating, gas, diarrhea and other symptoms in the gut. It turns out that FODMAP is an acronym for Fermentable Oligosaccharide, Disaccharide, Monosaccharides and Polyol. All of these substances are found in certain foods and are types of carbohydrates. Researchers in Australia found that these carbohydrates are not well absorbed by the small intestine in people with IBS. As a result, the substances stay in the gut rather than being used by the body and they pull water into the gut. The FODMAPs can also be fermented by the bacteria in the gut which produces gas. All of this can lead to a bloating feeling, pain and other symptoms.
Who makes the best medical student?
As I begin my 4th year interviewing prospective medical students, I am reminded of how challenging it is to figure out which applicants will possess all of the characteristics that I would want in my own doctor.
There is little question that we need to rethink the way we educate medical students to meet the needs of a changing healthcare system. Medicine is no longer a paternalistic practice where the doctor tells the patient what to do. Not only are patients becoming more empowered to participate in the own care, but they also have information at their fingertips about their own conditions and can access online discussion groups to talk with other patients about their shared experiences. The blog Wing of Zock looks at innovative ways to redesign medical education.
