Round up of articles on adult stem-cell research from FRC

I found these on their blog.

Adult Stem Cells–Saving Legs, Saving Lives

Excerpt:

Previous stories focused on the science of treating peripheral artery disease with adult stem cells. Often overlooked are the people whose lives have been changed or even saved by adult stem cell treatments.

Helen Thomas, 80, of Hastings, Michigan is one of those people. Helen’s painful circulatory problem in her leg meant she had trouble walking, rarely left home, and was facing amputation of her leg. But her physician, Kenneth Merriman of Hastings, asked around at a medical conference and found Dr. Randall Franz, who was doing a clinical trial at Grant Medical Center in Columbus, Ohio. Franz injected Helen’s own adult stem cells into her leg, causing new blood vessels to grow. Helen is now up and about, back to normal.

A Neurological Save with Adult Stem Cells

Excerpt:

When she was 30, Jennifer Osman was diagnosed with chronic inflammatory demyelinating polyneuropathy (CIDP), a neurological disorder that attacks the peripheral nervous system, progressively weakening and numbing its victim.

[…]Then Jennifer signed up for an adult stem cell study run by Dr. Richard Burt, chief of the Division of Immunotherapy at Northwestern University Feinberg School of Medicine. Her adult stem cells were collected and she received chemotherapy to knock out the rogue immune cells attacking her nervous system. Shortly after, on April 1, 2005, Jennifer received a transplant of her own adult stem cells and her immune system, now rebooted, began to rebuild itself. The process was slow and grueling, but she has taken no medication for the disease since 2008. Today, almost five years since her transplant, she is nearly symptom-free.

You Call That “Success”?

Excerpt:

A news story out yesterday exemplifies the “successes” of embryonic stem cells. The story proclaimed that scientists had “successfully used mouse embryonic stem cells to replace diseased retinal cells and restore sight in a mouse model of retinitis pigmentosa.” Sounds pretty good? Later there is the requisite hyperbole about treatments, that “Once the complication issues are addressed” and a list of retinal diseases that will be treated with embryonic stem cells.

Seeing Real Success with Adult Stem Cells

Excerpt:

In a paper published February 15, 2010, Oregon scientists showed that they could use bone marrow-derived adult stem cells to treat a rat model of retinitis pigmentosa. Visual function was significantly preserved in this study. An added benefit was that the cells could be easily grown in culture and administered intravenously; once injected, they traveled to the retina where they exerted their protective effect. The study highlights the possibility of using a patient’s own adult stem cells for treatment of retinitis, diabetic retinopathy, and macular degeneration.

A study by Canadian and Japanese researchers used human retinal stem cells that had been modified to increase their differentiation potential. When injected into the eyes of mice, the adult stem cells survived and differentiated into photoreceptors. Injected into a mutant mouse strain that lacks functional photoreceptors, the adult stem cells significantly improved visual function. The study was published online in the journal Stem Cells December 11, 2009.

Something to think about when the topic of embryonic stem cells comes up.

Cato Institute destroys the myths of inferior health care in the USA

The article is here by Michael Tanner of the prestigious Cato Institute.

Excerpt:

The Claim: Though we spend more, we get less.

The Facts: America offers the highest quality health care in the world. Most of the world’s top doctors, hospitals and research facilities are located in the United States. Eighteen of the last 25 winners of the Nobel Prize in Medicine either are U.S. citizens or work here. U.S. companies have developed half of all the major new medicines introduced worldwide over the past 20 years. And Americans played a key role in 80 percent of the most important medical advances of the past 30 years.

If you are diagnosed with a serious illness, the United States is the place you want to be. Tens of thousands of patients from around the world come to this country every year for treatment.

Critics of American health care often point out that other countries have higher life expectancies or lower infant mortality rates, but those two indicators are bad ways to measure the quality of a nation’s health-care system. In the United States, very low-birth-weight infants have a much greater chance of being brought to term with the latest medical technologies. Some of those low-birth-weight babies die soon after birth, which boosts our infant mortality rate, but in many other Western countries, those high-risk, low-birth-weight infants are not included when infant mortality is calculated.

Life expectancies are also affected by other factors like violent crime, poverty, obesity, tobacco, and drug use, and other issues unrelated to health care. When you compare the outcome for specific diseases like cancer or heart disease, the United States outperforms the rest of the world.

And one more myth:

The Claim: A government-run health-care system would expand access to care.

The Facts: The one common characteristic of all national health care systems is that they ration care. Sometimes they ration it by denying certain types of treatment altogether. More often, they ration indirectly, imposing cost constraints through budgets, waiting lines, or limited technology. One million Britons are waiting for admission to National Health Service hospitals at any given time, and shortages force the NHS to cancel as many as 100,000 operations each year. Roughly 90,000 New Zealanders are facing similar waits. In Sweden, the wait for heart surgery can be as long as 25 weeks. In Canada more than 800,000 patients are currently on waiting lists for medical procedures.

I wrote about US health care outcomes before in this post from the Hoover Institute at Stanford University.

Excerpt:

1. Americans have better survival rates than Europeans for common cancers. Breast cancer mortality is 52 percent higher in Germany than in the United States and 88 percent higher in the United Kingdom. Prostate cancer mortality is 604 percent higher in the United Kingdom and 457 percent higher in Norway. The mortality rate for colorectal cancer among British men and women is about 40 percent higher.2. Americans have lower cancer mortality rates than Canadians. Breast cancer mortality in Canada is 9 percent higher than in the United States, prostate cancer is 184 percent higher, and colon cancer among men is about 10 percent higher.

3. Americans have better access to treatment for chronic diseases than patients in other developed countries. Some 56 percent of Americans who could benefit from statin drugs, which reduce cholesterol and protect against heart disease, are taking them. By comparison, of those patients who could benefit from these drugs, only 36 percent of the Dutch, 29 percent of the Swiss, 26 percent of Germans, 23 percent of Britons, and 17 percent of Italians receive them.

4. Americans have better access to preventive cancer screening than Canadians. Take the proportion of the appropriate-age population groups who have received recommended tests for breast, cervical, prostate, and colon cancer:

  • Nine out of ten middle-aged American women (89 percent) have had a mammogram, compared to fewer than three-fourths of Canadians (72 percent).
  • Nearly all American women (96 percent) have had a Pap smear, compared to fewer than 90 percent of Canadians.
  • More than half of American men (54 percent) have had a prostatespecific antigen (PSA) test, compared to fewer than one in six Canadians (16 percent).
  • Nearly one-third of Americans (30 percent) have had a colonoscopy, compared with fewer than one in twenty Canadians (5 percent).

5. Lower-income Americans are in better health than comparable Canadians. Twice as many American seniors with below-median incomes self-report “excellent” health (11.7 percent) compared to Canadian seniors (5.8 percent). Conversely, white, young Canadian adults with below-median incomes are 20 percent more likely than lower-income Americans to describe their health as “fair or poor.”

6. Americans spend less time waiting for care than patients in Canada and the United Kingdom. Canadian and British patients wait about twice as long—sometimes more than a year—to see a specialist, have elective surgery such as hip replacements, or get radiation treatment for cancer. All told, 827,429 people are waiting for some type of procedure in Canada. In Britain, nearly 1.8 million people are waiting for a hospital admission or outpatient treatment.

7. People in countries with more government control of health care are highly dissatisfied and believe reform is needed. More than 70 percent of German, Canadian, Australian, New Zealand, and British adults say their health system needs either “fundamental change” or “complete rebuilding.”

8. Americans are more satisfied with the care they receive than Canadians. When asked about their own health care instead of the “health care system,” more than half of Americans (51.3 percent) are very satisfied with their health care services, compared with only 41.5 percent of Canadians; a lower proportion of Americans are dissatisfied (6.8 percent) than Canadians (8.5 percent).

9. Americans have better access to important new technologies such as medical imaging than do patients in Canada or Britain. An overwhelming majority of leading American physicians identify computerized tomography (CT) and magnetic resonance imaging (MRI) as the most important medical innovations for improving patient care during the previous decade—even as economists and policy makers unfamiliar with actual medical practice decry these techniques as wasteful. The United States has thirty-four CT scanners per million Americans, compared to twelve in Canada and eight in Britain. The United States has almost twenty-seven MRI machines per million people compared to about six per million in Canada and Britain.

10. Americans are responsible for the vast majority of all health care innovations. The top five U.S. hospitals conduct more clinical trials than all the hospitals in any other developed country. Since the mid- 1970s, the Nobel Prize in medicine or physiology has gone to U.S. residents more often than recipients from all other countries combined. In only five of the past thirty-four years did a scientist living in the United States not win or share in the prize. Most important recent medical innovations were developed in the United States.

Dissenting commenters should be sure to link their assertions to reputable sourcesm, and quote specific passages where the source agrees with their assertion and rebuts some claim made by the Cato Institute or the Hoover Institute. Please don’t cite the New York Times or the United Nations.

Planned Parenthood pushes intensive sex education onto 10-year olds

Story from Fox News. (H/T Protein Wisdom via ECM)

Excerpt:

The report, “Stand and Deliver,” charges that religious groups, specifically Catholics and Muslims, deny their young access to comprehensive sexual programs and education.

“Young people’s sexuality is still contentious for many religious institutions. Fundamentalist and other religious groups — the Catholic Church and madrasas (Islamic Schools) for example — have imposed tremendous barriers that prevent young people, particularly, from obtaining information and services related to sex and reproduction. Currently, many religious teachings deny the pleasurable and positive aspects of sex.” the report states.

The report demands that children 10 and older be given a “comprehensive sexuality education” by governments, aid organizations and other groups, and that young people should be seen as “sexual beings.”

[…]Michelle Turner, president of the Maryland-based Citizens for a Responsible Curriculum, said Planned Parenthood was simply trying to eliminate parental say.

“What are they trying to do? They are trying to eliminate the role of mom and dad in the family,” Turner said. “For Planned Parenthood to decide that governments, private organizations and religious organizations should make decisions about kids’ sexuality is just going too far.”

“It is part of a bigger push to change the way we think about sex,” she said. That sex is all about pleasure and there are no consequences. They are wrong. No matter how much we teach children, some will make mistakes. They will forget. And Planned Parenthood doesn’t want to deal with that,” she said.

“They see religious groups, especially those that counsel abstinence and waiting until marriage, as bad guys,” she added. “We aren’t.”

Remember Planned Parenthood’s revenue is proportional to the number of abortions they perform, so they have every reason to lobby the Democrats to pass laws that allow Planned Parenthood to bypass parents and entice children as young as 10 into sexual activity. It’s all about the money.
