we had another great meeting of the Galway SITP! We discussed all manner of things related directly, peripherally and not at all to our supposed topic, "Cults and New Age Movements".
Yolande provided us with a jumping off point with a list of top ten cults and brought us around to cycling, $cientology, doomsday cults, mormons and more.
Podge wants to bring our attention to this fund raising activity in aid of St. Jude's Children's Hospital. It's all in honour of Dr. Burzynski's 70th Birthday - look, it's complicated. :) Follow the link through or come join us on our Facebook Page for more details. We're going to make a mass donation in the name of Galway Skeptics. Get in touch with us on the Facebook Page or via email if you want to help them out!
Come join us on the 28th for more Galway Skeptics in the Pub!

Yolande, Podge and Charles all presented great mini-talks on failed Apocalypse predictions - Harold Camping, Apocalypse Predictions as a resource and Y2K respectively.
You can find their presentations here. Give me a heads-up if the link doesn't work.
Huge shout out to the Galway Humanists from NUI,G- their Auditor, Peter, came to join us and start a process of linking up between us and them.
As part of revitalizing the blog, we'll do our best to put up a summary of every meeting we have. Keep an eye out for more blog updates and synopsises on our fortnightly meetings! Any feedback as to how to present/the content for these updates would also be hugely appreciated.
Our next regular day would be on the 31st of December, so there's no way we'ld have peace and quiet in our regular to discuss Science in a sensible fashion, so our next actual meeting is on the 14th of January, 2013.

That said, I have no intention of ignoring this statistic; lets take a further look at the data provided in this study and perhaps come to some understanding of what it means. Helpfully recorded along with the number of suicides per 100,000 we also find the number of deaths by homicide and unintentional injuries. In both cases, the risk to women who have had an abortion is higher - in the case of injury almost twice as high as the risk to the general population of women (20.4 vs 10.8 / 100,000) and more than five times higher than the population of pregnant women (20.4 vs 3.9 / 100,000). The risk of homicide displays a similar pattern; women who have had an abortion are more than three times as likely to be killed violently than a women in the general population (7.7 vs 2.1 / 100,000) and eleven times more likely to be murdered than a pregnant women (7.7 vs 0.7 / 100,000). Eleven times more likely! I wonder why those making these claims decided to focus on the comparatively paltry six times increase in the number of suicides among women who have had an abortion when there existed a much larger and more shocking increase in the rate of homicide occurring to the same group? Could it perhaps be that it is much harder and more taxing on one’s credulity to draw a link between abortion and homicide rates than it is to draw a link between abortion and suicide rates? The data doesn't show a causative abortion-suicide link specifically; rather, those making this claim rely on the reader's presumption that there must be an intrinsic, common sense and causative link between abortion, guilt and suicide. What this data in fact shows is not that there is a cause and effect relationship between abortion and suicide, but rather that women who are more likely to have an abortion are also more likely to be killed by accident or violence, including suicide, than those who do not have one. To take it a step further - women who in their day to day life are more likely to suffer a fatal injury, become suicidal or be murdered are also more likely to have an unwanted pregnancy, and thus choose to have an abortion. Rather than being a causative factor, an abortion is much more likely to be a symptom of whatever underlying cause is also making these women more likely to be murdered or suffer a fatal accident. While this is in some sense shocking, it is not exactly surprising. Such data was sadly not gathered in this study, but I would not be terribly surprised to find that those women who choose to have an abortion may also be more likely to come from abusive homes or be economically disadvantaged, both factors associated with a higher incidence of violence, mental illness and abortion. While this data does not show that there is no causative link between abortion and suicide, neither does it demonstrate that there is; much like a tasty but ultimately irrelevant sponge cake, it informs us very little in this matter. Rather than being an argument against abortion, this data is instead an argument for greater post abortion support services, and perhaps follow up investigations to look at the social and economic situations of women who choose to have abortions and determine if some form of assistance is appropriate. In summary, while I do not doubt that the notion of a causative link between abortion and suicide will continue to be bandied about, if you feel the urge to perpetuate such a hypothesis please note that the above studies support for your claim is dubious at best.
P.S. In this post I have focused mainly on debunking a specific claim, which in fairness to the authors of the paper they did not themselves make without qualification: the conclusion surmized that "The increased risk of suicide after an induced abortion indicates either common risk factors for both or harmful effects of induced abortion on mental health." As I'm sure is clear, I tend toward the former suggestion, as the evidence does not goes as far as supporting the latter. In general, the literature has shown either no or little difference in mental health outcomes for unwanted pregnancies which end in abortion or are carried to term. Regardless, the practice of shaming such women should be roundly condemned, as studies have shown a causative relationship between social exclusion and suicide risk. For those interested in more recent and broader ranging studies that specifically address the relationship between abortion and mental health, I would direct you towards a 2011 systematic study by the National Collaborating Centre for Mental Health as a good starting point.

Stanislaw Burzynski sells a number of things, among them are books, movies and cancer treatments. The primary thing Mr. Burzynski sells, however, is hope. Hope is a powerful and heady treatment; it can do many things. It can help your friends and family to raise money for expensive overseas treatments. It can inspire well know bands to, with the best of intentions, donate a signed guitar to help raise funds for the same reason. Hope can bring you succor during the darkest times of your life, it can help you through tough times and give your the courage to face another day of suffering. The one thing it can't do, however, is cure cancer. And if the hope you are sold is false, if it costs you and your family their livelihood and potentially your life, then it is worse than worthless, and those who sell it are opportunists and vultures of the lowest order. An author might be indulged for a moment to imagine that, when such vultures as these gather in their circling, fetid flocks, they may pause in their horrid shrieking and take a moment to murmur to each other across the winds a single name; "Burzynski ".
Stanislaw Burzynski was born in 1943 in Poland, where he received his education and qualifications, and later moved to the USA to practice and conduct research. In 1977 he founded the Burzynski Clinic in Huston, Texas, with the intention of treating people with what he calls Antineoplastons, a group of substances isolated and extracted from urine by none other than himself. He was featured on day time TV back the in the 80's as a genius doctor possessed of a miracle cure to otherwise incurable cancers. Several of the patients touted as 'cured' on the show later died, but this failed to stop Burzynski, or the myth of his miracle cure. Antineoplastonshave been tested by other institutes in Japan and elsewhere, but only Burzynski's own studies have turned in positive effects in the treatment of cancer. In 1990's the state of Texas came down hard on Burzynski; he's been found guilty of health insurance fraud, been ordered to cease and desist advertising his products as cures for cancer, and has been ordered to stop selling them without FDA approved clinical trials. How is it that Burzynski is still in business? Well, he's conducting those trials of course. Expensive, costly trials of consistently unproven treatments that you can take part in. For a price. Somewhere in the region of €75,000 euros per year, in fact.
You're back - excellent. So, given that Burzynski has been so well torn apart by Orac, and others, why am I writing about him again? Well, for a simple reason. Last year a movie was release called Burzynski - Cancer is Big Business which details the trials and tribulations of this modern day Hippocrates. It paints him and his treatment in the best possible light, and has unfortunately catapulted the Burzynski Clinic back into the limelight. It was shown last year in alternative health centers and nutritional centers throughout Ireland, even appearing in our very own Galway. Unsurprisingly, this has lead to a wave of desperate people in Ireland and England to seek treatment from this... man. You may have already heard of a toddler in Cork who died after her parents choose Burzynski's treatment over chemotherapy. There are Burzynski fundraisers going on right now in cities across Ireland, run by good, well meaning people who are earnestly trying their best to save a friend or loved on from death. This kindness and goodwill will all be for naught if the treatment funded turns out to be unproven, useless rubbish. In England, Radiohead are selling a signed guitar on E-bay to raise money for the Billi Butterfly Fund to pay for cancer treatment at Burzynski's clinic for a four year old girl with inoperable brain cancer, whose mother is also suffering from breast cancer. I'm not going to link to Billi’s site, because frankly you don't want to read it. It is literally heartbreaking. The brave will find it as the first hit if the google the phrase above. This girl's cancer may not be treatable conventionally, I have no idea, but this money would be better spent on palliative care, on research funding, on a trip for Billi to Disneyland, or on literally anything else. Instead it's going to line the pocket of a cancer quack with a very real body count to his name.
So please, if you know anyone thinking of spending money on Stanislaw Burzynski, or the Burzynski Clinic, then please, be considerate, be understanding and be supportive. But also please be sane, and just direct them towards Orac's blog, or here, or any of the other solid skeptical sites that have investigated him. It's likely you'll be met with hostility; often criticism is interpreted as negativity, but do it anyway. There's a very real chance you'll save a life.

Above: A humble flower smartbomb - destroying all cancers, perhaps?
Well, I'm sure glad that's over. Cancer will affect 1 in 3 of us, so no self respecting news paper would ever sensationalise a headline like this unless humble flower smartbombs, hereafter referred to as HFSBs, really were destroying cancers left right and centre. Right? Well, no, unfortunately not. Though there is a fascinating story here, and a potentially promising cancer treatment which may even see use in a few years, a magic bullet to fix all cancers there is not. At least, not yet.
The story focuses on the work of Laurence Patterson and his team at University of Bradford, UK, who have worked up a rather interesting potential treatment for solid tumorous cancers. (Note that this treatment is aimed at tumours only, despite the headlines promise of a treatment for all cancer.) Using an extract from the autumn crocus called colchicine, they plan to attack tumour cells directly by inhibiting cell growth and blood flow to cancer. Colchicine itself has been tested in this role in the past, and has actually worked quite well. There is, however, a downside; colchicine is toxic enough to rule it out for cancer treatment, and has even been historically used as a poison. In order to get around this rather serious downside, Petterson's team did some clever molecular hacking on the colchicine itself, rendering it harmless unless it combines with an enzyme called matrix metalloproteinase-1, or MMP1. This enzyme occurs naturally in the body, but in much larger quantities in tumours. It's role in the body is in the breakdown of intercellular collegen; tumours use it to expand their size and network of blood vessals. Thus, the Colchicine remains harmless until it runs into a tumour and becomes toxic again, halting the growth of or outright killing the cancer.
Or so goes the theory. To read the Herald's, and many other media outlets take on this, the treatment is essentially ready. Unfortunately this is far from true, with Patterson's team still firmly in the preclinical stage. So far the modified colchicine has been used only on mice infected with grafted human tumours, and even at this stage was effective on only half the mice tested, and only then in some trials. The quantities required to treat humans could still turn out to be toxic, or any other number of problems could arise, as it always the case with pre-trial drugs. While there is talk of going to human trials in the next 18 months, it is unfortunately still a little too early to get overly excited about this potential treatment. In fact, the article is mostly based on a recent talk which mirrors a paper released in 2010. So why exactly is this making the papers just now? Well, it could have something to do with the fact that Patterson is currently trying to drum up the roughly €3 million required to bring the drug to trials.
While I don't want to rain on anyone's parade, least of all Patterson and his team's who have done some really excellent science thus far, it nevertheless remains the case that the general media tends to fail badly when it comes to science reporting. For every dozen potential cancer treatments which arise, there is perhaps one which ever sees use in treating humans. Is it too much to ask for a little perspective?
