94 Percent Accurate

1 Blood Test to Diagnose Alzheimer’s Being Developed

Researchers at UT Southwestern Medical Center have isolated a set of blood serum proteins that might provide an accurate diagnosis of Alzheimer’s disease, particularly when it’s coupled with a clinical exam. Tests thus far have shown a 94 percent accuracy rate in detecting Alzheimer’s and were 84 percent accurate in ruling out the disease, say researchers. Scientists have sought a simple blood test to diagnose Alzheimer’s for years. "This research uses a novel technology that makes it possible to analyze several biomarkers in a single blood sample in a cost-effective way," says senior author Dr. Ramón Díaz-Arrastia. Alzheimer’s, which affects 5.3 million Americans over age 65, is difficult to diagnose in its early stages and a definitive diagnosis is possible only after death.

Three Servings a Day Recommended

2 Less Than 1 in 20 Eat Enough Whole Grains

Less than 5 percent of young American adults consume at least three servings of whole grains daily, according to a new study published in the October issue of the Journal of the American Dietetic Association. The analysis included over 7,000 men and women between the ages of 19 and 50 years old who reported eating less than two-thirds of a serving each day on average. Although the study was conducted between 1999 and 2004 before food labels began promoting the health benefits of whole grains, study author Carol O’Neil of Louisiana State University said that it is unlikely that the percentage has changed much in the past six years. “People just don’t eat whole grains,” she said, despite evidence that people who eat whole grains have overall higher quality diets.

Especially If They Are Free

3 Structured Weight Loss Programs Successful

People who participate in structured weight loss programs are often more successful than those who attempt to diet and exercise on their own, according to new research in the Journal of the American Medical Association. In particular, programs that incorporated exercise from the start had more successful patients than those who dieted first and delayed physical activity until later. However, an accompanying study found that if the program were offered for free, patients are even more likely to maintain weight loss. Women who received free meals provided by Jenny Craig in addition to either in-person or telephone support were more likely to lose at least 5 percent of their original body weight. Twelve weeks at Jenny Craig can cost as much as $1600 for counseling and food.

a Pill a Day

4 Fake Food Capsule Keeps Hunger at Bay

On Sunday, at the 28th Annual Scientific Meeting of The Obesity Society, researchers from Calgary (Canada) presented results from a small pilot study in which they used a fake “pseudofood” capsule to promote satiety and fullness, causing participants to eat less and lose weight. The treatment was being studied as an alternative to the intragastic balloon, an invasive procedure that reduces gastric volume. Four people took a gelatin capsule orally that was made of expandable, absorbent fiber and polymer granules called pseudobezoars for one month. The participants reported feeling less hungry during the study, and the researchers determined that so far, the treatment appeared safe with few side effects reported.

First Patient Enrolled

5 First Government Approved Stem Cell Study Started

A company name Geron Corp. has started the first government approved study to treat humans using embryonic stem cells. The first patient has been enrolled in the preliminary study to determine safety and tolerance to the treatment. The patient suffered from a recent spinal cord injury and was being treated at Shepherd Center in Atlanta. To be eligible, the injury had to occur within two weeks prior to treatment. The treatment, called GRNOPC1 is injections of progenitor cells that differentiate into oligodendrocytes, the cells that produce myelin so impulses can move from nerve to nerve. The injections will be between the third and tenth thoracic vertebrae. Future trials will look at milder injuries and ones that occur in other areas of the spine.

Full-Term Babies at Highest Risk

6 Danish Study Suggests Jaundice and Autism Linked

A study conducted in Denmark suggests that autism in kids may be linked to jaundice, a condition that typically occurs in new born babies when bilirubin is produced faster than the liver can metabolize it. Researchers looked at 733,826 kids born between 1994 and 2004, 35,766 who were born with jaundice and 577 who were diagnosed with autism at a later date. Researchers took into account other factors that might affect their risk and found that full-term babies born with jaundice had a 56 percent increased risk of developing autism. Those born before 37 weeks and in the spring and summer were not affected. Dr. Rikke Damkjaer Maimburg hypothesized that that with jaundice, "bilirubin crosses the blood-brain barrier and destroys brain cells, as we know it does in cerebral palsy."
