A Call for Change: Is Greater Transparency Necessary in Modern Day Medical Research?

“With great power comes great responsibility” - Voltaire




THIS, in just the past two weeks:

HEADLINE, JULY 30, 2014: Dutch Investigation Finds Serious Flaws In Influential New England Journal Of Medicine Study.

HEADLINE, AUGUST 5, 2014: Japanese Scientist whose stem-cell research had to be retracted when it proved to be false commits suicide. 

WHAT is happening within the world of medical research?

FOR a quick and illustrative summary of the disturbing increase in the number of retracted scientific papers, please take a moment and check out this link: http://www.nature.com/news/2011/111005/full/478026a.html






OH sure, there have always been stories about competition and rivalry amongst the scientific elite. The hallowed halls of academia are littered with them: Newton v. Hooke; Darwin v. Wallace v. The Establishment; but fabricated or intentionally skewed data? Come on now Science; we hold you to a higher degree of conduct. Heck, back in the day, a double Nobel Prize winner could receive a humiliating thrashing for rushing prematurely to publication. And why? Because despite his esteem and despite his credentials, he was wrong. And his colleagues could prove it. (Thank you very kindly Rosalind Franklin et al.) So what has changed?

OKAY so we've all been there; you know, those agonizing scarlet-faced seconds when you wish you could take back the words you've just said. But there is no taking them back. Sure, your apologies and contrite expression show you are not without manners, humility and conscience; but still, it is a difficult elephant to vanquish from the room. Now imagine that instead of seconds we are talking about months and years; and that the words coming out of your mouth are deliberate and have the potential to affect millions of lives. Lives of people who have placed their trust in the profession of which you are representative.

RECENTLY, I came across an article in The Economist telling of how attempts to reproduce results of several 'landmark' cancer studies fell far short of expectation, with a reproducibility ratio of 6 out of 53. The article goes on to suggest the need for some degree of improved transparency within the scientific community. The need for a system to be put in place which, in essence, would help keep the scientific community honest. Scientists are only human after all; and are under an enormous amount of pressure to produce and publish results; this while competing for scant funding and research grants which often come with implicit strings attached.

IN light of this disturbing trend, I could not help but be reminded of the 1998 Andrew Wakefield et al study, which through the publicity machine, came to be known as the study linking the MMR (measles, mumps & rubella) vaccine to autism. The study was originally published in The Lancet. The study was retracted in 2010.

"Following the judgment of the UK General Medical Council's Fitness to Practise Panel on Jan 28, 2010, it has become clear that several elements of the 1998 paper by Wakefield et al1 are incorrect, contrary to the findings of an earlier investigation.2 In particular, the claims in the original paper that children were “consecutively referred” and that investigations were “approved” by the local ethics committee have been proven to be false. Therefore we fully retract this paper from the published record." 
"The British General Medical Council (GMC), which registers doctors in the United Kingdom, has decided that Dr. Andrew Wakefield should be struck from the medical register for "serious unprofessional conduct." In January 2010, the GMC Fitness to Practice Panel concluded that Wakefield had acted dishonestly and irresponsibly in connection with a research project and its subsequent publication. The fitness-to-practice hearing, which started in July 2007, centered on a study of children by Wakefield and twelve others that linked the measles-mumps-rubella (MMR) vaccine with autism and bowel problems. Subsequent studies found no connections, but sensational publicity caused immunization rates in the UK to drop more than 10%. Ten of the study's authors have since renounced its conclusions; and Lancet's editor said he should not have published the study and that Wakefield's links to litigation against the manufacturers of the MMR vaccine were a "fatal conflict of interest." 


I'VE read the original Wakefield et al. paper; read it again and again. And were it not for the publicity machine surrounding it, I can’t imagine it having received the mainstream attention it did. In the authors' own words: "We did not prove an association between measles, mumps, and rubella vaccine and the syndrome described." There was no conclusive evidence of any kind. Still, the authors hinted at causal links throughout, ending the discussion section with: "In most cases, onset of symptoms was after measles, mumps, and rubella immunisation. Further investigations are needed to examine this syndrome and its possible relation to this vaccine."
The authors' choice to end the paper in that manner seemed an odd one to me, when, (granted my partiality always sways toward things genetic) this was the section which had drawn my attention:

“A genetic predisposition to autistic-spectrum disorders is suggested by over-representation in boys and a greater concordance rate in monozygotic than in dizygotic twins.15 In the context of susceptibility to infection, a genetic association with autism, linked to a null allele of the complement (C) 4B gene located in the class III region of the major-histocompatibility complex, has been recorded by Warren and colleagues.24 C4B-gene products are crucial for the activation of the complement pathway and protection against infection: individuals inheriting one or two C4B null alleles may not handle certain viruses appropriately, possibly including attenuated strains.”

WHY did this draw my attention?

Since genetics were acknowledged as a potential contributing factor, it seemed deserving of at least an equal amount attention as the MMR vaccine itself.
WHY?
Well, because perhaps if back in 1998 such an association had been given more than an honourable mention, the option of genetic screening prior to vaccination could have by this time become an acceptable alternative to outright refusal. (And yes, I do realize I'm speaking in hypotheticals; and yes, the genetic component was just one of several noted, but that is exactly my point: whatever the authors' intent, their actions and subsequent actions may have caused the forest to be obscured by the trees.)


IN case anyone is wondering, yes I did do a Google search for ‘scholarly articles supporting link between MMR and autism;’ and I'm not saying they don't exist, just that my efforts returned a whole lot of this:



THAT said, here are a few links from the 'other side' of the vaccine story:



AS WELL, www.thelibertybeacon.com, provides a list of "28 studies from around the world that support Dr. Wakefield's research." (Scroll to the bottom of the web page for the list.) And yup, I did read them; read them all; read them 'till my eyes went dry. Yup, yup, yup ... But the truth is, I'm still not seeing it ... Okay, so they did say 'support' not 'prove'; and 'support' can be interpreted in many ways, right? Well, as I prefer to reserve my proselytizing for topics upon which I have a concrete stance, (like my aversion to altered data, skewed facts and biased interpretations in scientific papers) perhaps it is best if I invite you to read the studies for yourselves. After all, we, each of us, have our own unique set of criteria upon which our opinions are formed.


IT IS estimated that nearly two million scientific papers are published each year, with only a relative handful ever reaching the mainstream. The original Wakefield et al paper should never have reached the mainstream. The study lacked controls, full stop. And it is impossible for the interpretation of data from any scientific study, conducted in the absence of controls to render any definitive conclusions. And yet it has reached the mainstream, and now we find ourselves engaged in a dangerous standoff of my science trumps your science.


It is a very human need indeed, the need to know why. It is essential to our survival and often driven by how directly the answers sought affect us personally. And it is a question which remains at the heart of the scientific endeavor. We place our confidence and trust in scientists, and with good reason. But in order to maintain that trust, perhaps it has become necessary to open the window, even just a sliver, as this would go a long way toward ebbing the tide of falsified, biased and redundant research. Falsified, biased and redundant research which, when seeped into the mainstream, has consequences which no amount of retracting can undo. With lives on the line, the current trend cannot continue. Immediate changes need to be implemented in order to protect the interests of both the researchers and those who rely on the important work they do.
