New blood tests for TB show exposure to disease while tuberculin skin tests do not

Two new interferon-gamma blood test assays to detect latent tuberculosis infection (LTBI) showed customers were exposed to a supermarket employee in Holland who had smear-positive tuberculosis, while traditional tuberculin skin tests (TST) did not, according to a large contact study.

1. Folic acid lowers blood arsenic levels, according to Mailman School of Public Health study
   10-08-2007 · EurekAlert!
   A new study by researchers at Columbia University Mailman School of Public Health finds that folic acid supplements can dramatically lower blood arsenic levels in individuals exposed to arsenic through contaminated drinking water. This toxic element is currently a significant public health problem in at least 70 countries. Chronic arsenic exposure is associated with increased risk for skin, liver and bladder cancers, skin lesions, cardiovascular disease, and other adverse health outcomes.

2. Colon cancer proteins show promise for blood test
   06-15-2007 · EurekAlert!
   Searching for less invasive screening tests for cancer, Johns Hopkinsscientists have discovered proteins present in blood that accuratelyidentify colon cancer and precancerous polyps.Initial studies of the proteins, CCSA-3 and CCSA-4, suggest they couldbe used to develop a blood test to identify at-risk individuals.

3. Jefferson immunology researchers show blood-brain barrier damage could affect MS severity
   04-05-2007 · EurekAlert!
   Immunology researchers at the Kimmel Cancer Center at Jefferson studying a multiple sclerosis (MS)-like disease in mice have shown that the amount of "damage" to the central nervous system’s protective blood-brain barrier -- in essence, opening it -- almost always correlates to the severity of the disease. The findings can be used for testing potential MS therapies and for better understanding the role of the blood-brain barrier in disease processes.

5. Cognitive scores vary as much within test takers as between age groups making testing less valid
   07-01-2007 · EurekAlert!
   How precise are tests used to diagnose learning disability, progressive brain disease or impairment from head injury? Timothy Salthouse, Ph.D., a noted cognitive psychologist at the University of Virginia, has demonstrated that giving a test only once isn't enough to get a clear picture of someone's mental functioning. It appears that repeating tests over a short period may give a more accurate range of scores, improving diagnostic workups.

   Giving elderly patients certain general anesthetics could increase their risk of developing Alzheimer's disease and other memory and attention problems. This is according to recent test tube and animal studies which are beginning to show that certain anesthetics reduce the rate at which brain cells are born and develop.

   Physicists and medical researchers for the first time have demonstrated a new technique that non-invasively measures in real time the level of damage to the skin from sun exposure and aging, and initial results suggest that women's skin ages faster than men's. Findings appear in the October 1 issue of Optics Letters, a journal of the Optical Society of America.

10. Under-used colon cancer screening test is effective
    09-25-2007 · EurekAlert!
    New Kaiser Permanente study in Journal of the National Cancer Institute shows that an under-used fecal occult blood test specific for human blood is a better screening test for colon cancer than the stool screening tests most frequently used - the unrehydrated guaiac test and the sensitive GT -- because it finds more polyps and cancers. This new FIT test may help improve colon cancer screening rates and may be a popular alternative to colonoscopies.
