Poll Still Finds Public Support for Health-Care Reform

While a majority of Americans still think health-care reform is needed now, some of that support has wavered slightly as Congress wrestles with the details of producing a reform package, according to the July Kaiser Health Tracking Poll.

Fifty-six percent of Americans continue to believe that health reform is more important than ever, despite the country's economic problems. And by a better than two-to-one margin (51 percent to 23 percent), Americans think the country would be better off if Congress and President Barack Obama enacted health reform, the poll found.

But concerns raised during the Congressional debate appear to be influencing some people's views. For instance, a larger share of the public is more worried that Congress and the president will pass a bill that's bad for their family (54 percent) than that health-care reform won't happen this year (39 percent). And while a majority of Americans still favor reform now, the percentage of people who hold that view has dropped from 61 percent to 56 percent since June, the poll found.

The proportion of people who say passage of health-care reform would make things worse for their own family, although relatively small, has doubled since February (from 11 percent to 21 percent), as has the proportion of Americans who say the country would be worse off if health-care reform passed -- from 12 percent to 23 percent, according to the poll.

And while the estimated $1 trillion price tag over 10 years for health-care reform has been a sticking point for many in Congress, it seems to be a little less worrisome for those polled. When asked if $1 trillion was too high, too little, or about right, 42 percent said it was too high, 36 percent said it was the right amount, and 9 percent said it was too little.

Study Looks at Implanted Pig Cells to Treat Type 1 Diabetes

In a trial that could one day lead to a way to slow the ravages of type 1 diabetes, a New Zealand company announced Thursday that it plans to implant newborn pig cells into eight people with the blood sugar disease.

The Associated Press reported that these cells produce insulin that the researchers are hoping can be used to lower blood sugar levels in these volunteers. However, a company official told the wire service that such a treatment will not eliminate all the symptoms of type 1 diabetes indefinitely, which include blindness, premature heart disease and poor blood circulation that can lead to the amputation of limbs.

Critics have also expressed concern that putting these pig cells into humans might introduce a new virus into the human population, a fear that company officials said is unfounded.

"There is no evidence of a risk of retrovirus infection," Bob Elliott, medical director of Living Cell Technologies, told AP. "Nobody has developed a retrovirus."

Elliott stressed that the pigs being used in this trial come from isolated islands south of New Zealand, and are being kept in a sterile environment. He also noted that he has run two previous trials, the first with six patients in New Zealand in 1995-1996. A Russian trial with 10 patients began two years ago. In those trials, the cells that weren't rejected produced insulin for roughly a year, although the cells in one patient continued generating the hormone for 12 years.

The pig cells that will be implanted in this latest trial are coated in a membrane made from seaweed, which will eliminate the need for immunosuppressant drugs, according to company officials.

With type 1 diabetes, the body mistakenly attacks the pancreas to the point where the organ stops producing the insulin needed to break down sugars in the blood and convert it to energy.
