The Roundup: featuring the hygiene hypothesis, antibiotic resistance, a breath test for obesity, and more.
Blast from the past
I’ve written before about the hygiene hypothesis, which holds that the disappearance of “old friends” (relatively benign microbes and helminths) that we co-evolved with has increased the prevalence of autoimmune and inflammatory disease. This will be the subject of my talk at AHS ’13, so it’s exciting to see this fascinating topic coming up more frequently in mass media. For example, a recent article in the Smithsonian Magazine discussed how an inadequate exposure to dirt could explain why some of the wealthiest countries suffer from afflictions rarely seen in less-developed nations. And a new study suggests that genes that predispose to modern, inflammatory diseases like Crohn’s and rheumatoid arthritis have been positively selected for because they conferred greater protection against infectious disease, consistent with the hygiene hypothesis.
- An article at the Smithsonian blog explains how Daylight Savings Time and other sleep losses can negatively impact your body. (I just did a seminar on this topic for the Healthy Life Summit)
- A new study determined that doctors need to give antibiotics to more than 12,000 people with acute respiratory infections to prevent just one of them from being hospitalized with pneumonia.
- The New York Times discusses how the crisis of antibiotic resistance is getting worse, thanks to 80% of all antibiotics being used for livestock.
- A recent study suggests that a breath test profile of microorganisms inhabiting the gut may be able to tell doctors how susceptible a person is to developing obesity.
- A new study finds that over-diagnosis of reflux in infants leads to needless medication, which is generally ineffective and could have long term implications.
