KU researcher tests drug to combat alcohol abuse
BY GRETCHEN WIELAND
A dietary supplement could prevent alcoholism in people who have a genetic propensity toward alcohol abuse, according to preliminary findings by a KU researcher.
Ann Manzardo, research assistant professor of psychiatry and behavioral science, said research showed a link between a deficiency in thiamine — a B complex vitamin — and alcoholism.
She is currently testing whether Benfotiamine, a dietary supplement that activates thiamine in the body and dramatically increases levels of the vitamin, could both help alcoholics kick their dependencies and lower the risk that people with thiamine deficiencies will become alcoholics.
"A thiamine deficiency has long been linked to alcoholism," Manzardo said. "We now believe that the deficiency may be predisposing people to alcoholism instead of being the result of alcoholic behavior."
Thiamine helps to break down sugars and turn them into energy. The heart and nervous system are especially prone to a deficiency, which occurs when proteins do not "turn on" the thiamine to run throughout the body. Thiamine also keeps nerves functioning normally.
Manzardo's theory, which appeared in the September issue of Alcoholism: Clinical and Experimental Research, suggests that some babies inherit insensitivity to thiamine that inclines them to alcoholism later in life. This adds to proven data that alcoholism is a genetic disease.
Manzardo said that white matter, a fatty substance that protects cells in the nervous system, sometimes does not develop properly in the first few weeks of life when there is a thiamine deficiency.
"Individuals with white matter
damage may have impaired judgment when using alcohol and may be less able to stop themselves from drinking too much," Manzardo said.
Previous studies have found that children of alcoholic parents develop at a slower rate, and their motor skills are especially impaired. White matter damage in the brain that results from a thiamine deficiency is now believed to be the cause of those developmental issues.
Children who have white matter damage to the brain develop more slowly and are much more likely to become alcohol dependent by age 30 than those who develop at a normal rate.
"Sons and daughters of alcoholics are two to four times more likely to become alcoholics themselves," Manzardo said.
Wally Mechler, a Lawrence counselor licensed to treat alcohol addictions, said that significant medical research had linked alcoholism and genetics.
"Between 60 and 70 percent of my patients actively report that they have at least one parent who is an alcoholic." Mechler said.
Alcoholism is difficult to study because the gene connected with the disorder has not yet been found and gathering the data from birth to adulthood is an extensive process. However, if Manzardo's theories prove correct, isolating the gene may become easier.
Manzardo said she would like to interview preteens with an inherited thiamine deficiency before they began drinking and to interview them again 10 years later to find out how many had become alcoholics.
The dietary supplement Manzardo is currently testing may alter how genetic alcoholism is treated.
Benfotiamine was created in the 1960s to help the nervous system process alcohol and to abate the side effects of drinking. It has recently
been used to help diabetics, who have blood sugar problems that relate to the thiamine deficiency. A diabetic's body can break down sugars properly with the aid of Bofentiamine.
Manzardo said the drug activated the body's thiamine, increased the vitamin's levels and had been shown to improve brain function in alcoholics.
"We will see if the supplement has an effect on drinking and whether it will help alcoholics recover," Manzardo said.
The supplement has been successful in Europe at reducing the symptoms of nervous system conditions involved with alcoholism, and no adverse effects have been found after a decade of use. Manzardo said Benfotiamine could eventually be used to help those who had the thiamine deficiency before they abused alcohol.
"Ultimately, it makes sense to give it to pregnant women or babies," Manzardo said, "especially people who have a high risk for alcoholism."
However, Manzardo said she would not recommend this without extensive testing that proved there were no negative side effects.
Mechler said that there were many available medications now that helped combat alcohol cravings, but that he saw potential in Benftotamine. He also said an entire lifestyle change was the key to fighting alcoholism.
"If it was approved by the correct governing agencies, I would advocate anything that is safe to help." Mechler said. "I promote supplements, and it is also about a holistic lifestyle."

BIRTH CONTROL PATCH WARNING
The birth control patch may cause HEART ATTACKS, STROKES & BLOOD CLOTS
Recently, the FDA approved updated labeling for the Ortho Evra birth control patch, warning users that the Ortho Evra patch exposes women to higher levels of estrogen than most birth control pills.
Increased levels of estrogen may cause heart attacks, strokes, pulmonary embolisms, deep vein thrombosis (DVTs) or blood clots in women using the Ortho Evra Birth Control Patch.
If you or someone you know has experienced a heart attack, stroke, pulmonary embolism, deep vein thrombosis or blood clots while using the Ortho Evra birth control patch, you may be entitled to substantial monetary compensation.

Astronauts prepare for launch
Simulation allows crew to become familiar with vehicle

CAPE CANAVERAL, Fla. — The space shuttle Discovery's seven astronauts flew to Florida on Monday for several days of dress rehearsal in preparation for their Dec. 7 launch on a mission to the international space station.
Led by commander Mark Polansky, the astronauts will run through emergency escapes from the launch pad, practice landing on Kennedy Space Center's runway and learn how to put out fires on the shuttle. The dress rehearsal culminates Thursday with the crew
"It's a chance for us to get a lot of training and see our vehicle on the pad for the first time," Polansky said after landing at the Kennedy Space Center.

During the 12-day mission, Discovery will rotate out a space station crew member, and its astronauts will rewire the space lab's electrical system.
sion next March. Foam breaking free of the external tank has vexed NASA ever since a piece of foam struck the space shuttle Columbia's wing during liftoff in 2003, causing a gash that allowed fiery gases to penetrate the spacecraft. Seven astronauts were killed.
Meanwhile, NASA managers in New Orleans reviewed a possible design change to the shuttle's external fuel tank and could decide this week to modify the tank for a mis-
The space agency has spent three years trying to figure out how to keep foam loss to a minimum.
Also this week, NASA planned to test-fire solid rocket motors in Utah to see whether their illumination provides enough light to take photographs of the external tank at night. Discovery is set to be the first night launch in four years.

Kline's defeat due to combination of missteps

Kline waged a two-year legal battle to obtain patient records from two abortion clinics.

election cycle.
He wrote a "church" memo to his campaign staff that the Washington-based Interfaith Alliance described as the worst abuse of religion in American politics during the 2006
"He was plagued by missteps and misstatements and people who disliked him picking at him for four years."
None of those issues, by itself, was fatal to Kline's re-election, given his advantage as a Republican in a GOP-leaning state. But together, they drained away his political capital until the result was inevitable
Kline said his nephew deserved a second chance and has turned his life around, but there was an inconsistency between that message and Kline's persistently tough-on-crime rhetoric.

Morrison captured 58 percent of the vote to Kline's 42 percent, in a state where Republicans account for nearly 46 percent of all registered voters.
"We anticipated by time election day rolled around that (Kline) was going to lose by double digits," Republican State Chairman Tim Shallenburger said in an interview.
