Do Clinical Trials Work?

pillsA NY Times article asking “Do Clinical Trials Work?” stirred up lots of questions about the challenges of using experimental designs. Read here Clinical trials (also called experimental designs) are often referred to as “the gold standard” of research. In social science, they are hard to do; when they are used, the results are often inconclusive. Somehow, I thought science might be different, but at least in terms of health research on drugs, the results are also often disappointing, according to the author Clifton Leaf. Continue reading »

Views on Occupational Groups: Military high, Lawyers Low

pew perception of occupations 2013This out from PEW: Public Esteem for Military Still High, Clergy in the Middle, Lawyers at the Bottom, POLL July 11, 2013
PEW asked about 10 occupations in terms of their perceived contribution to society.

They wrote:
“Americans continue to hold the military in high regard, with more than three-quarters of U.S. adults (78%) saying that members of the armed services contribute “a lot” to society’s well-being. That’s a modest decline from 84% four years ago, the last time the Pew Research Center asked the public to rate various professions. But the military still tops the list of 10 occupational groups, followed closely by teachers, medical doctors, scientists and engineers. A solid majority of the public says each of those occupations contributes a lot to society.

“By contrast, just 37% of Americans surveyed think the clergy make a big contribution to society, about the same as in 2009. Regular churchgoers tend to be more positive about ministers, priests and other clergy members. But even among adults who say they attend religious services at least once a week, only about half (52%) rate clergy in general as contributing “a lot” to society, while 29% say the clergy make “some” contribution, and 11% say the clergy contribute “not very much” or “nothing at all.”

“While there have been modest declines in public appreciation for several occupations, the order of the ratings is roughly the same as it was in 2009. Among the 10 occupations the survey asked respondents to rate, lawyers are at the bottom of the list. About one-in-five Americans (18%) say lawyers contribute a lot to society, while 43% say they make some contribution; fully a third (34%) say lawyers contribute not very much or nothing at all.”

Asking Tough Questions about Research Studies

I am not the only one who is trying to make it easier for people to make sense of research results. For those who are interested in health and nutrition, the number of studies can feel overwhelming, not to mention conflicting.  Here is a webpost from Chris Kresser about how to read and understand scientific research. Interesting comments as well. Asking tough questions are essential.

Taxing the Rich?

This from Paul Krugman’s blog: Taxing the Rich post

He writes: “First, over the past three decades we’ve seen a soaring share of income going to the very top of the income distribution (right scale) even as tax rates on high incomes have fallen sharply, with the recent Obama increases clawing back only a fraction of the previous cuts.”

 

The essential question is simply this:  what income distribution is best for America as a whole? Does inequality hurt the economy, and if so, how much income inequality can be tolerated before it harms the economy? Given that we have a consumer-based economy, if people are limited in the amount of consumption because they have limited resources, at what point does the economy stall? At what point does it make an economic recovery fail?

The same question can be posed about taxes. What is the best tax structure for America as a whole? There is no question in my mind that the Bush-era tax cuts were a huge failure from the perspective of both the federal deficit and the debt. We quickly went from a budget surplus to a budget deficit, that got worse as the economy continued to weaken. Other factors played a role, but when the budget started to cross into the red, and especially with the costs associated with two wars, the tax cuts should have been canceled. Continue reading »

Frances Kelsey: Science in the Public Interest

Sometimes it is nice to read a story about  how one person can make a difference, someone who can use the standards of science to stand up to the corporations who put profit over public safety, and who can win. It is especially heartening when that someone is a public administrator.  That person is Frances Kelsey, and Truthout published this story:

kelsey“You’ve probably never of her, but she may have saved your life. In the early 1960s, Kelsey – a doctor and research scientist with the FDA – saved thousands of babies from severe birth defects by stopping a big pharmaceutical company from marketing the drug thalidomide. Equally important, Kelsey’s courageous stance inspired Congress to revise the rules for approving new drugs protecting hundreds of millions of Americans, then and now, from unsafe medicines.

Kelsey’s battle with the makers of thalidomide is not only an inspiring tale of how one individual’s expertise and courage protected the public interest against the corporate push for profits, but also a warning to drug companies and their lobby groups fighting new drug safety rules that would put public health and safety over drug company profits.”

She demanded scientific evidence that the drug was effective but that it also did not produce harmful side-effects.

Frances Kelsey: 1962 stopped thalidomide in 1962
