(Ivanhoe Newswire) — The next time you have a bad hair day, think twice before you point fingers at the weather … your genes may be to blame!

Researchers at Columbia University Medical Center have uncovered a gene involved in determining hair texture in humans. Mutations in the P2RY5 gene cause hereditary “wooly” hair — hair that is coarse, dry, tightly curled and sparse.

Since wooly hair is most commonly found in Pakistani families, researchers performed a genetic analysis of six families of Pakistani origin with hereditary wooly hair. The mutated P2RY5 gene was clearly found mutated and deemed the cause for the family’s hair texture.

Some California physicians say a recent settlement between a Ventura hospital and the Dept. of Justice underscores the importance of a self-governing medical staff.

Community Memorial Hospital in December 2007 agreed to pay $1.5 million to settle allegations that the facility gave improper gifts, loans and payments to some doctors in exchange for Medicare patient referrals. No doctors were named in the agreement, and the hospital did not admit any wrongdoing. Community Memorial administrators voluntarily disclosed the financial relationships, which took place under the hospital’s former leadership.

Washington — The halting on Feb. 6 of an arm of the large type 2 diabetes trial, ACCORD, sent shock waves through the medical community. The lower-the-better conventional wisdom for blood glucose levels was questioned when it was found that those getting the most intensive glucose-lowering treatments were more likely to die.

But treatment strategies — keeping blood glucose, blood pressure and cholesterol levels in check — are likely to remain unchanged for the vast majority of the millions of people with type 2 diabetes. What might change is an overly aggressive pursuit of low blood glucose levels in patients with or at risk for cardiovascular disease.

Washington — A new Medicare coverage policy on drug treatment for anemic cancer patients is hurting care, according to a survey of doctors released last month.

Ninety-one percent of oncologists and hematologists reported adverse patient events in the 12 weeks after the July 30 implementation of the national coverage determination on erythropoiesis-stimulating agents. The poll was sponsored by U.S. Oncology, which funds, develops, and helps manage 443 cancer centers in 39 states. It surveyed 307 physicians from Nov. 26, 2007, to Dec. 11, 2007. The organization limited the number of affiliated physicians involved in the poll to 20% of all respondents.

(Ivanhoe Newswire)  Now that the FDA has declared meat and milk from cloned animals is safe to eat, a number of companies are producing cloned animals for the livestock industry.  Some are already marketing semen from clones.

A poll done by Consumers Union found that 89 percent of consumers want their food labeled to indicate whether it’s from cloned animals.   But should access to DNA from every unique clone be made public?  Patrick Cunningham of Dublin’s Trinity College and Chief Scientific Advisor to the Government of Ireland thinks so.

(Ivanhoe Newswire) — Carbon dioxide gets a lot flack. It’s a culprit responsible for the growing hole in our ozone layer, leading to skin cancer, climate change and global warming. But CO2 has a surprising new role: reducing wrinkles and clearing up acne scars!

Trials of a new carbon dioxide-based fractional laser are underway at two medical centers in the United States. The laser — recently approved by the U.S. Food and Drug Administration — is designed to treat facial wrinkles and acne scarring, alleviating dark pigmentation, and other conditions that the centers are investigating before making the laser widely available.

(Ivanhoe Newswire) Currently, pathology reports and PSA levels are all that doctors have to predictor whether a man’s prostate cancer will spread or come back. New research done at the Oregon Health & Science University Cancer Institute has uncovered a biomarker that can significantly improve on what’s available.

Dr. Joshua Alumakal, MD conducted a study on men with localized prostate caner examining DNA and a gene modification process called methylation in which tumor suppressing genes like CDH13 are turned off. With the tumor-suppressing gene turned off, there is nothing to put the brakes on cell growth and spread. 

(Ivanhoe Newswire) — Before you take your next cigarette puff, beware! If you are one of the majority of people with a common genetic defect, you are likely to suffer from an early heart attack.

“We’ve all heard the stories: Someone’s great-uncle has smoked three packs of cigarettes since he was 14, and now, at the age of 88, he’s living a fine, healthy life,” Arthur Moss, M.D., director of the Heart Research Follow-up Program at the University of Rochester Medical Center, was quoted as saying. Now, scientists say they have figured out why some smokers are luckier than others: they lack a defect of the gene CETP (cholesteryl ester transfer protein) found in 50 percent to 70 percent of the population.
