I agree that the concerns Michael indicates are potentially valid ones, and that they are worth considering.

Hm....I wonder what reputable scientists might think about the credibility of references used to make health claims to support the use of Piracetam that supposedly come from research published by the patent holder of Piracetam -- if they do not seem to exist? I wonder. [glasses] A lot of people seem to like that House MD dude; but I don't have a TV (on purpose, I might change one day and decide to get one, who knows?), so I don't really know for sure what criteria he would use to support the use of any drug or supplement -- but I am confident the script writers would not be so negligent to cast an MD who is unaware of the convention of peer review...
These days almost everyone already knows of the necessity for a little convention called
peer review. I guess we should assume there are some "newbs" here...so for their sake (hey, I was a newb once too!):

Peer review (known as refereeing in some academic fields) is a process of subjecting an author's scholarly work or ideas to the scrutiny of others who are experts in the field.
It is used primarily by editors to select and to screen submitted manuscripts, and by funding agencies, to decide the awarding of monies for research.
The peer review process is aimed at getting authors to meet the standards of their discipline and of science generally. Publications and awards that have not undergone peer review are likely to be regarded with suspicion by scholars and professionals in many fields. Even refereed journals, however, have been shown to contain error, fraud and other flaws that undermine their formality. In the case of manuscripts, the editor will pass manuscripts that are accepted for publication to a publisher who will be responsible for organizing redactory services, printing and distribution of the publication. In specialist academic (scholarly) journals, the editor (or increasingly group of editors) is normally a well-respected academic in the field, and edits the journal on behalf of a learned society or a commercial publisher. Some journals have professional editors employed by the publisher (e.g. Nature) or the charity (eg Science) owning the journal. Most academic publishers have commissioning editors who solicit books from appropriate authors. An editor is ultimately responsible for the quality and selection of manuscripts chosen to be published, usually basing their decision on peer review, although the authors are always responsible for the content of each manuscript. The editor does not revise and correct spelling and grammar - that process is carried out by a 'Copy Editor' (again, the editor controls the quality of this process).
Reasons for peer reviewA rationale for peer review is that it is rare for an individual author or research team to spot every mistake or flaw in a complicated piece of work. This is not because deficiencies represent needles in a haystack, but because in a new and perhaps eclectic intellectual product, an opportunity for improvement may stand out only to someone with special expertise or experience. For both grant-funding and publication in a scholarly journal, it is also normally a requirement that the work in both novel and substantial. Therefore showing work to others increases the probability that weaknesses will be identified, and with advice and encouragement, fixed. The anonymity and independence of reviewers is intended to foster unvarnished criticism and discourage cronyism in funding and publication decisions. However, as discussed below under the next section, US government guidelines governing peer review for federal regulatory agencies require that reviewer identity be disclosed under some circumstances.
In addition, since the reviewers are normally selected from experts in the fields discussed in the article, the process of peer review is considered critical to establishing a reliable body of research and knowledge. Scholars reading the published articles can only be expert in a limited area; they rely to some degree on the peer-review process to provide reliable and credible research which they can build upon for subsequent or related research. As a result, significant scandal ensues when an author is found to have falsified the research included in an article, as many other scholars, and the field of study itself, has relied upon that research. (See below peer review and fraud.)

It is, however, the "further" that caught my eye in his statement regarding South''s lack of reliability. In other words, it seems that Michael is adducing South's alleged lack of reliability as
more evidence of his critique, and is not merely limiting it to the issue at hand in his post.
[/quote]
Well, the truth of the matter is -- once again -- there is no evidence
strong enough to pass a peer review that might suggest Piracetam is an effective cognition enhancer for healthy individuals. So, the real issue we should be focused upon is ensuring such research is conducted as soon as possible so we can move forward to other (from my perspective), more promising compounds.
[quote]
Also, while I agree that it is problematic for an inventor of a substance and an employee of the company that produces it to publish studies favorable to his drug, it seems also problematic to chase such a person from the field and forbid him from doing so. I thought that the solution to such a dilemma was to publish in peer-reviewed journals. I do not know how damning it is to be published in a non Medline-indexed source, but it would be damning, indeed, to publish such research in a non peer-reviewed journal.
Further, do you or anyone else know for what journal this citation form, " Prog. Neuro-Pharmac.", stands? I ran a Google search using this abbreviation, and could find only the references to it in South's article and in this forum. That fact suggests to me the possibility that the citation form in South's article could be incorrect. Until we know the journal name, and search for it again in Medline, I would be hesitant to accept as a matter of fact that it is a non Medline-indexed journal.
[/quote]
The abbreviation might mean something...however, that does not change the fact that the study in question was
supposedly published by the patent holder...it can be proven that more than 50% of published research is faulty...

Why Most Published Research Findings Are False
John P. A. Ioannidis
Summary
There is increasing concern that most current published research findings are false.
The probability that a research claim is true may depend on study power and bias, the number of other studies on the same question, and, importantly, the ratio of true to no relationships among the relationships probed in each scientific field. In this framework, a research finding is less likely to be true when the studies conducted in a field are smaller; when effect sizes are smaller; when there is a greater number and lesser preselection of tested relationships; where there is greater flexibility in designs, definitions, outcomes, and analytical modes; when there is greater financial and other interest and prejudice; and when more teams are involved in a scientific field in chase of statistical significance. Simulations show that for most study designs and settings, it is more likely for a research claim to be false than true. Moreover, for many current scientific fields, claimed research findings may often be simply accurate measures of the prevailing bias. In this essay, I discuss the implications of these problems for the conduct and interpretation of research.

In any case, I do not have copies of his articles handy, but I am reasonably certain that South's citations are all not so potentially tainted as this one. I could be mistaken, of course.
[/quote]
Once again, I'd like to repeat that the quest for the strongest evidence is part of thinking scientifically and has
nothing at all to do with James South, MA.
[quote]
Agreed, but this is a difficulty we all face. That is why I assume you advocate independent testing and freely available, meaningful COAs. What I dislike intensely is our friend the FDA's using this fact to try to take from us the choice of whether to assume this risk.
[/quote]
I advocate independent testing because it can mean the difference between life and death. I don't trust that many people and for good cause. It comes down, over and over again, to one critical point --
evidence.
Let's suppose I purchase product "x" from supplier "y." Supplier "y" tells me that product "x" is "z" pure. Because supplier "y" has a
conflict of interest implicated by the fact he or she can profit from the sale, it is therefore highly probable that supplier "y" could claim product "x" is "z" pure when it in fact is only "z - k" pure. Similarly, a man can claim to a woman (or vice versa) that he's never engaged in sexual activity, therefore he carries no STD...however, because a man might experience more sense pleasure from engaging in an unprotected sexual act, there can exist s a conflict of interest in the claiming -- all the reason for independent testing of potential mates as unregulated drugs and/or supplements that are highly likely to end up inside your body and can cause as much or more damage than your average STD.
So, yeah, I'm in favor of results of independent testing of anything my body comes in contact with. While it may be true that the body is temporary, I still think we should cherish it as it is seems to be the vehicle for the soul.

True enough, but I do not think that this would apply to prescribing a substance such as Piracetam, though. Malpractice would would have to result in demonstrable harm in order to be actionable, and it is difficult to imagine a plausible set of facts resulting from Piracetam usage that would lead to such harm. In addition, the verdict would be very fact-specific, and would turn on the specific disease in question, the specific preferred treatments in question, what exactly the accused physician did and did not do, and the like.
[/quote]
Malpractice is technically a term used to define the implementation of a therapy that can be construed in a court of law as not the accepted method. Hypothetically, if it can be demonstrated that a physician administers a therapy to his or her patient when there is a more generally accepted method -- a lawsuit can be filed and damages can be awarded to the plaintiff. So, if a physician is administering a therapy to his or her patient to treat a supposed condition that has a more well accepted (by the medical community) treatment, he or she could be forced into a long (and expensive!) court proceeding. Most doctors I've met try to minimize the possiblity that they end up having to litigate expensive lawsuits -- therefore, the doctors I've met and work with tend to stick to the evidence and drugs that are legal to prescribe.
[quote]
I had planned simply to ask him for what purposes he prescribes it, in general.
[/quote]
I've studied particular compounds more than a doctor or two I've worked with. However, at the end of the day, I can't write myself a prescription. In addition to holding a licence to practice medicine, a Doctor of Medicine also needs to be registered with the
DEA, so having a clean criminal and medical record are just prerequisites (for me at least).
[quote]
Exactly. This remains the problem with determining the efficacy of so many natural (read, "non-patentable and unprofitable") substances. It is quite frustrating. I am very glad to read that there may be possible solutions forthcoming, though.
Very true, but the state boards are a quick and free way to check the record of a physician that one is considering. I imagine, though, that the levels of information and usefulness vary from state to state.
[/quote]
Yes, the state boards can give you some very helpful information. I just put the joke about checking out ex girlfriends criminal records as a joke because I hope mine are checking mine out; because mine is as clean as can be.

Regards. I hope that examinations are done, or nearly so.

It is now vacation time. I am probably going to stay down in SD as long as my school's gym is open.
A lot of strong, peer reviewed evidence has recently been published in the media that suggests that having a vigorous physical fitness program as part of a healthy diet (this includes the right supplements and such) is "the" way to go when it comes to living a long and healthy life. Being physically fit also might increase the chances of my genetic profile being passed sooner and in a more fertile mate than otherwise possible.

I am quoting myself above for posterity's sake because I included what I consider to be an accurate representation of the term "peer review," and I think the WSJ article quoted below fits here the best.
I think maybe we should first try to determine if we can find a significant difference between the definition of "peer review" on approximately December 15, 2006 (quoted above) and today -- June 17, 2007:

These definitions look very similar...however, I think it might be important to note what ImmInst advisor Dr. Brian Wowk wrote on Oct 31 2006:
[quote]
There is a reason why many institutions (not just in science) require correspondence in writing, not emails or Internet posts. It's too easy to put forth half-formed ideas and out-of-context information in brief Internet posts.
Forums, blogs, and wikis are intrinsically undisciplined media. The barriers between having a thought and publishing the thought are way too low. Even worse, if a Wiki with broad access politically positions itself as an authority on some subject, scientists who really are authorities will have to spend inordinate amounts of time on edit wars rather than getting real work done. This is not how science gets done. [/quote]
The bottom line I guess is Wikipedia itself is not peer reviewed! Any random person can log in and write whatever they choose, so I generally cross check whatever data I may find at a Wikipedia page with a stronger source of evidence (usually a primary source).
Here's the article that I think fits here the best. Note this is an article published in The Wall Street Journal -- the one Newspaper that holds more captive eyes of the US financial market than any other News publication in the world (ask your stock trader). One usually does not encounter as many scientific-focused publications on WSJ as one might find as other newspapers may, but WSJ sure covers the markets!
...however, this is an excellent article that's probably worth your attention. I won't really comment here because this is over my head -- however, I have indeed highlighted some of the more controversial segments... [sfty]

The Wall Street Journal: News SourcePolitical Peer ReviewJune 18, 2007; Page A16
Does this sound familiar? A questionable survey finds that an FDA-approved pharmaceutical may carry some risks. A respectable but increasingly politicized medical journal publishes the research and attaches an alarmist commentary. A media panic ensues. Democrats ride the story to kick up support for what they wanted to do all along, which is increase regulation over "Big Pharma." Meanwhile, the complex science is trampled in the commotion.Well, it's not Vioxx -- at least not yet. The latest drug panic concerns Avandia, a medicine used to treat diabetes. The facts aren't all in, but that didn't impede Representative Henry Waxman from calling the controversy "a case study of the need for reform of the nation's drug safety laws." Since the next flashpoint will inevitably come with the meeting of an FDA advisory panel on July 30, let's review what we know.
* * *
Avandia, or rosiglitazone, is a sophisticated drug that works at the gene level to lower blood sugar in diabetics; manufactured by GlaxoSmithKline, it was approved by the Food and Drug Administration in 1999. The accusation is that Avandia increases risks for cardiovascular problems, including heart attacks, according to a study published in May in the New England Journal of Medicine (NEJM). It was accompanied by an editorial encouraging physicians to stop prescribing Avandia and condemning the FDA's "desultory approach" and "regulatory failure." That all but guaranteed a round of press hysterics.Sure enough, first-time Avandia prescriptions are down 40%, and down overall by 20%. Endocrinologists and their patients were bound to be wary, but the NEJM study was problematic. Steven Nissen of the Cleveland Clinic employed a statistical technique called meta-analysis, which pools data from smaller clinical trials to suggest overall trends. Meta-analysis can be a useful contribution to medical knowledge, but it is in no way conclusive.
Several aspects of the Nissen study are particularly troubling. The assertion that Avandia raises the absolute risk for heart attacks by 43% relied on a methodology that excluded data in which there were no reported adverse events, skewing the results. The NEJM editorial itself acknowledged that "A few events either way might have changed the findings" and that "the possibility that the findings were due to chance cannot be excluded." Even the Lancet, the British medical journal with its own politicization issues, clucked about the NEJM's "alarmist headlines."
FDA critics say the agency's failure was to insufficiently warn Avandia patients of these risks, whatever they were; and that this is particularly egregious because diabetics are already prone to heart disease. But the reverse is also true: The high cholesterol and blood pressure, obesity and other conditions associated with diabetes might account for any problems, not Avandia. Correlation is not causation.Besides, the data Dr. Nissen analyzed did not control for cardiac events, so things like indigestion and heartburn may have counted. GlaxoSmithKline is conducting its own clinical trials, which are more rigorous, to be concluded next year. The interim results showed that Avandia patients had a 7% decrease in heart attacks, and a 17% decline in deaths from cardiac events, though these aren't yet definitive either.
The larger political context here is the evidence of collusion to gin up one more drug-company "scandal." Dr. Nissen has a reputation as an adversary of the pharmaceutical industry, and was involved in the controversy that led Merck to withdraw Vioxx from the market in late 2004. He admitted that he consulted with several Congressional committees, including Mr. Waxman's, before the NEJM published his Avandia paper. At a Waxman hearing, Dr. Nissen said he shared his "preliminary analysis" and "discussed some pending legislation." Ostensibly serious medical research isn't supposed to be peer reviewed by the Democratic majority.
The pending legislation is Mr. Waxman's counterpart to the Senate's Enzi-Kennedy drug safety bill, which, if passed, will bolster the FDA's authority to require postmarket testing. But it's hard to tell why Avandia is the "case study" for this agenda: GlaxoSmithKline was already engaged in extensive postmarket trials before this scandal broke -- beyond those that would be required by Enzi-Kennedy. And Glaxo makes the data from its completed trials transparent on the Internet, where Dr. Nissen acquired it in the first place. So much for Mr. Waxman's repeated claims that Big Pharma is suppressing negative results.
Avandia will now be getting a "black box" warning from the FDA, the most stringent possible regulation short of a ban. Though the controversy will no doubt escalate with the July 30 FDA review, Avandia will probably remain available to patients and their doctors for some time. For now, that's better than the Merck situation, with Vioxx off the market and the company mired in litigation.
At bottom, the Avandia fuss is political, not medical, and it turns on risk itself: how to strike the best balance between patient safety and lifesaving therapies. The FDA already does too much onerous bottlenecking of new drugs. Those who think otherwise ought to make an honest case -- not rely on political sensationalism.[/quote]
Peace and love.
