The more coffee a person drinks, the lower their risk of developing liver cancer, suggests a large study.

University of Helsinki researchers found that coffee seems to be connected to lower blood levels of gamma-glutamyltransferase (GGT), a liver enzyme involved in the secretion and absorption of bile that has been linked to liver cancer.

The researchers studied 60,323 Finnish participants aged 25 to 74 — all had no cancer at the start of the study — in seven surveys between 1972 and 2002. Participants were tracked until June 2006.

People who participated in the study had to complete questionnaires about their medical history, diet and lifestyle, and income.

They were also asked how many cups of coffee they drank a day and divided into groups based on those findings. The groups were broken into 0-1 cup, 2-3 cups, 4-5 cups, 6-7 cups and eight or more cups per day.

After an average period of follow-up of 19.3 years, 128 people involved in the study were diagnosed with liver cancer.

Researchers found that in the groups that drank the most coffee, the risk of developing liver cancer was the lowest, and that the risk was highest in those who drank less than two cups of coffee per day.

Those who had high blood levels of GGT and drank the least amount of coffee daily had the highest risk of liver cancer.

The reasons behind the seemingly protective role of coffee are unclear. “The biological mechanisms behind the association of coffee consumption with the risk of liver cancer are not known,” the authors write. They caution that the findings do not prove excessive coffee drinking staves off liver cancer.

The study is to be published in the July issue of the journal Hepatology.

Dogs Work “Magic” on Kids with Autism

Posted by stephcolin on Jul-18-2008

That’s how Karen Shirk explains the ability of service dogs to help children suffering from autism.

“I’m sure there’s some sort of scientific explanation,” she says. “But I call it magic.”

Since 1998, through her nonprofit 4 Paws for Ability, Shirk has helped partner service dogs with people with a wide range of disabilities.

It was Shirk’s own challenge in getting a service dog that led her to start 4 Paws.

In the late 1980s, while employed as a social worker in the field of mental retardation and autism, Shirk suddenly went into respiratory arrest. She was hospitalized off and on until 1992, when she was finally diagnosed with a rare neuromuscular disease.

Confined to a wheelchair and reliant on a respirator, Shirk set out to get a service dog so she could be more independent — but agencies turned her down, saying she was too disabled for a dog to make a difference in her life.

Frustrated, Shirk eventually decided to obtain a dog on her own. She found Ben, a black German shepherd puppy that, with the help of a trainer, became her service dog. With Ben by her side, Shirk regained a sense of optimism and control over her life.

“He gave me a reason to get up in the morning,” Shirk remembers. “I went from existing to living.”

Knowing there must be others like her, Shirk started 4 Paws in her apartment to help people who’ve been told they’re ineligible to get a service dog.

“We don’t discriminate against anyone who has a need,” she says.

Since many agencies have age restrictions, she now specializes in providing dogs to children. The dogs help kids with a variety of issues, from mobility problems to seizures, but from the start Shirk wanted to find ways to assist children with autism.

“I knew [autistic children] connected to animals,” she remembers. “I knew that service dogs would be able to help.”

She developed a program to train autism assistance dogs, and of the 319 dogs she’s placed since 1998, nearly 70 percent have been partnered with autistic children.

“The biggest problem that’s faced by families that have children with autism is isolation. They actually quit going out because they can’t keep their child safe,” says Shirk.

Shirk’s service dogs are taught a variety of methods to help keep kids with autism safe. Since many children tend to wander away and get lost, 4 Paws uses a technique called “tethering,” where the kids are tethered to their dogs while in public.

The parent — who always holds the leash — ultimately remains in control of both the dog and the child. Many dogs are even trained to track children who stray from home by following their scent. Video Watch a mother talk about the importance of her autistic son’s 4 Paws service dog »

Shirk says service dogs also give autistic children valuable emotional support. They’re taught to intervene when a child is frustrated, reducing tantrums commonly known as “meltdowns.” But Shirk believes one of the most important benefits is that the dogs are companions to kids who are often isolated.

Shirk’s 4 Paws for Ability requires that families raise $12,000, on average, to pay for their service dog. Each dog is trained for the child’s specific needs, and the entire process takes between nine and 18 months.

In the end, families come to Ohio to meet their dogs and receive training. For Shirk, seeing the kids bond with their dogs makes her efforts worthwhile. Video Watch how Shirk partners service dogs with children with disabilities »

“I love to see their faces and know that I was a part of that,” Shirk says. “It makes me feel good.”
