Yes, Please: New Non-Invasive Colon Screening Test

In a breakthrough that is likely to broaden the early detection of colon cancer without any of the unpleasantness associated with current screening techniques, the FDA has approved a non-invasive colorectal cancer screening DNA test called Cologuard. The test works by detecting DNA mutations and hemoglobin in stool samples. Patients testing positive then are told to follow up with colonoscopy.

In a large clinical trial of 10,000 patients, Cologuard accurately detected more advanced adenomas and colorectal cancers than fecal immunochemical testing. The new test, however, did not correctly rule out cancer as accurately as the older test. The FDA notes that this approval does not change the U.S. Preventive Services Task Force's guidelines, which recommend screening using colonoscopy, sigmoidoscopy or fecal occult blood testing.

The arrival of this new screening technology comes none too soon as two new studies in JAMA Internal Medicine have found that colonoscopy may be over-prescribed for older adults. In the first, researchers calculated nine-year mortality risk for roughly 27,000 people aged 65 and older who completed the National Health Interview Survey. For participants with a nine-year risk of 75 percent or higher:

  • 55 percent of men had a PSA test within two years;
  • 38 percent of women had a mammogram within two years;
  • 31 percent of women had a Pap test within three years;
  • 41 percent of men and women had colorectal cancer screening within five years.

How Active Does Your City Make You?

In a study of how street network design affects public health, researchers at the University of Colorado Denver and the University of Connecticut have discovered that older, more compact cities promote more walking and biking and are generally healthier than many newer cities.

It was previously known that people drive less and walk more in more compact cities with more intersections per square mile, but the new research has been able to link these qualities to better health.

The study looked at 24 medium-sized California cities with populations between 30,000 and just over 100,000. The researchers examined street network density, connectivity and configuration. Then they asked how these measures of street design impacted rates of obesity, diabetes, high blood pressure, heart disease and asthma. The study used data collected by the California Health Interview Survey for the years 2003, 2005, 2007 and 2009, sampling between 42,000 and 51,000 adults.

The results showed that increased intersection density was significantly linked to reduction in obesity at the neighborhood level and of obesity, diabetes, high blood pressure, and heart disease at the city level. The more intersections, the lower the disease rates.

The study also found a correlation between wider streets with more lanes and increased obesity and diabetes rates. The reason, the researchers said, was that wider streets may be indicative of an inferior pedestrian environment. The presence of a big box store also tends to be indicative of poor walkability in a neighborhood and was associated with a 13.7 percent rise in obesity rates and a 24.9 percent increase in diabetes rates.

Overall, the healthiest cities had shorter blocks and more intersections. The myriad advantages of fostering walkable places include the lower levels of traffic fatalities. Choosing a place to live based on health outcomes is not a new idea, but cityscape viewed through the lens of fitness may be an emerging consideration. The new findings suggest that, while it is possible to lead an active, healthy lifestyle in most any type of neighborhood, people living in more compact cities do tend to have better health outcomes.
