Cancer epidemiology
tsmith | March 13, 2007I was out yesterday, and as such missed Lynn Margulis' blog tour stop at Pharyngula. For those who may not be familiar with Margulis, she's a professor at the University of Massachusetts, Amherst, and was the one who pushed the (now accepted) idea that chloroplasts and mitochondria in cells came about due to symbiosis. In the post announcing her impending arrival, there were lots of questions about her stance on HIV/AIDS. This is mostly due to a review she co-authored on Amazon of Harvey Bialy's biography of HIV denier Peter Duesberg. The review ends: "As both Bialy and Duesberg…
tsmith | January 5, 2007From the Seed mothership: Cancer is due to 'fate', Britons believe
More than a quarter of people believe that fate alone will determine whether they get cancer, not their lifestyle choices, according to a survey conducted by charity Cancer Research UK.
The poll of more than 4,000 adults across the country asked people if they thought they could reduce their risk of getting cancer or whether it was out of their hands.
A total of 27 percent of people said cancer was down to fate, with more women than men believing cancer was a matter of destiny than prevention through measures such as quitting…
tsmith | January 4, 2007I ran across this story study linking breast cancer protection to housework while browsing Scienceblogs briefly over the break (GrrlScientist mentioned it here), but hadn't had a chance until now to read through the actual publication. As usual, I'm late; Orac has a good overview, as well as some comments made by other bloggers railing against "feminism" and how this study proves that feminist philosophy kills women.
First, here's how the BBC story describes it:
Women who exercise by doing the housework can reduce their risk of breast cancer, a study suggests.
The research on more than…
tsmith | October 6, 2006Regular readers out there will already be familiar with the groups of people who deny evolutionary theory, who deny that HIV causes AIDS, even those who deny that germs cause disease, period. Wilhelm Godshalk is even on the record for denying gravity. I don't know what it is about this site, and science blogs in general, that bring people out of the woodwork in this manner, but we have another live one. Witness Charles Hoy's assertion that fear, not smoking, causes lung cancer.
What evidence do you want? Lung cancer is as common in smokers as it is in non-smokers. Where it all gets…
tsmith | September 14, 2006The new vaccine against the human papilloma virus is something I've discussed a time or ten here. Reaction to the vaccine by many religious groups has morphed with time, from outright resistance to a more common stance right now that they're accepting of the vaccine, but don't want it to be mandatory. Well...
Michigan legislation would require girls to get HPV vaccine
Michigan girls entering the sixth grade next year would have to be vaccinated against cervical cancer under legislation backed Tuesday by a bipartisan group of female lawmakers.
The legislation is the first of its kind in the…
tsmith | August 15, 2006I've blogged previously about the massive effect vaccines against the human papilloma virus (HPV) could have. HPV is a common sexually-transmitted virus. Though most strains are harmless, a few have the potential to cause cervical cancer. Therefore, the HPV vaccine will be the first one ever specifically intended to prevent a type of cancer.
This vaccine has recently been approved by the FDA, and is set to roll out shortly. This is already expected to be a rather contentious issue as the vaccine is rolled out in the U.S. and elsewhere, as one target group for vaccination is adolescents…
tsmith | July 31, 2006I was busy over the weekend (and disgusted by the hot, nasty weather that will not die), so I don't have a lot on tap for today. Luckily, though, there's some interesting stuff elsewhere that's already written up--thoughtfully saving me some of the trouble.
I discuss the link between infectious and "chronic" disease with some regularity on this site. I think it's a fascinating area; perhaps oversold by some, perhaps over-criticized by others, but certainly a hot topic and an interesting direction for research in microbiology. This weekend's New York Times had a new story that touched on…
tsmith | July 19, 2006Despite the fact that abortion is a public health issue, I don't write on it much. It's so emotionally charged, and I can only handle so many trolls at one time. However, regardless of one's position on abortion, we should be in agreement that women shouldn't be lied to at such a trying time--but it would seem that's the case:
Women who consult with pregnancy resource centers often get misleading information about the health risks associated with having an abortion, according to a report issued Monday by Democrats on the House Government Reform Committee.
Congressional aides, posing as…
tsmith | June 23, 2006Rebecca over at Memoirs of a Skepchick makes an excellent argument against the new HPV vaccine:
Before the invention of the fire extinguisher in 1816, people used sensible fire safety precautions. They did not leave oily rags piled in buckets next to the ashtray. They did not set their farts on fire. And they always kept their curtains far away from heating devices.
After the invention of the fire extinguisher, all hell broke loose. It didn't take long for games such as "Tie a Lit Sparkler to the Cat" and "Flaming Monopoly" to explode -- literally and metaphorically -- in popularity all over…
tsmith | June 11, 2006Like a Saturday roundup, but a day delayed. Some other topics I found interesting this week, but didn't have a chance to elaborate on...
Afarensis mentions new research on the evolution of the Crenarchaeota, a group of archae.
Laura Bush speaks on the President's malaria initiative.
Both Ed and Janet muse on the FDA approval of the new HPV vaccine--and ramifications thereof.
Via Eastern blot, 2006's Art of Science winners.
Wanna work at Seed? They're looking for fall interns; deadline is July 6th.
And of course, don't forget to send in your submissions for this week's Animalcules…
tsmith | June 7, 2006Antibiotic resistance gets a lot of attention, but it's not the only kind of drug resistance that's of concern. Derek of In the Pipeline has a post up discussing resistance to cancer therapies.
tsmith | May 6, 2006Just a few things that have either been sitting in my drafts box and I know I won't have a chance to get to, or stuff I saw elsewhere that deserves a mention.
Check out this excellent (and hilarious) post by Skip Evans on creationists and boobies.
I've posted previously here about our eagles here in Iowa. Phil at the Bad Astronomy Blog gives links to 2 webcams, where you can watch the nests of eagles or peregrine falcons (another favorite bird of mine). They've shut down the eagle one because the eggs didn't hatch and the parents left the nest, but there's a fluffy white falcon chick (…
tsmith | April 10, 2006So, Linus Pauling is apparently the hot topic of the day. Janet's already discussed a bit about the whole "wacky older scientist" phenomenon over at Adventures in Ethics and Science, while the first post cited gives you a bit of the background of Linus Pauling, bringing in two new studies on the topic of vitamin C as a treatment for cancer. Since Janet's covered a bit more of the philosophy and sociology of the topic, I just thought I'd weigh in a bit on the science of the issue, particularly since Lee makes it seem as if Pauling has been unfairly maligned.
Here's what Lee claims happened…
tsmith | April 1, 2006At the risk of starting an infectious cancer/HIV/AIDS fight over at The Loom, I'll point your attention to Carl's post discussing, well, those topics here. He elaborates on a study I mentioned here but didn't delve very much into the science. Zimmer does--check out the link to find out how he relates it to HIV.
tsmith | March 18, 2006 I discussed the so-called "cervical cancer vaccine," a multivalent vaccine protective against several strains of the human papilloma virus previously here. In the new issue of the New England Journal of Medicine, there's a
perspective on the vaccine, and issues surrounding it:
Genital HPV infection is common, with an estimated 6.2 million new infections each year in the United States. Although most infections are asymptomatic and transient, persistent infection with oncogenic HPV types is a serious health issue. Cervical cancer is the 11th most common cancer among women in the United States…
tsmith | March 14, 2006I mentioned yesterday that Mike had a post on the war on epidemiology. That might sound a bit strange--doesn't have quite the ring to it as Chris's book. But, never fear, epidemiology is indeed under attack--or, at least, it's being redefined by young earth creationists.
In a pair of articles published in the esteemed journal, Creation Research Society Quarterly, Jeffrey Schragin has put forth his argument that "the Bible's epidemiology is scientifically sound" and that the "Creation Health Model (CHM) offers a more comprehensive understanding of health and disease than standard molecules…
tsmith | February 24, 2006This time for prostate cancer.
In a surprising discovery, researchers say they have found a virus in some prostate cancer patients, a finding that opens new research avenues in the most common major cancer among men in the United States.
The virus, closely related to one previously found only in mice, was found in cancerous prostates removed from men with a certain genetic defect. The researchers, with the University of California, San Francisco and the Cleveland Clinic, warn that they have not discovered any links between the virus and prostate cancer, but they were nonetheless excited about…
tsmith | February 10, 2006You've probably seen this announcment trumpeted somewhere: "Cancer deaths fall for first time." I just wanted to post a very brief note on this. First, let's look at their numbers:
The number of cancer deaths dropped to 556,902 in 2003, down from 557,271 the year before, according to a recently completed review of U.S. death certificates by the National Center for Health Statistics.
It's the first annual decrease in total cancer deaths since 1930, when nationwide data began to be compiled.
Now, a decrease in cancer deaths is always a good thing, but talk about making a mountain out of a…
tsmith | February 3, 2006I've noted previously that infectious causes of so-called"chronic" diseases--illnesses such as cancer, heart disease, and autoimmune disease--are an interest of mine. The Guardian has a nice overview of infectious causes of cancer--and why one can't simply "catch" cancer as you catch a cold. It's a much better article (or at least headline) than this one, which discusses recent findings that a few types of adenovirus could play a role in the development of obesity. However, this does not mean--as the headline suggests--that "obesity is contagious." You're not going to "catch fat." Even…
tsmith | January 25, 2006I wrote about a recent study investigating a possible connection between melatonin and the development of breast cancer here last week. coturnix--who knows this field much, much better than I--has more discussion on serotonin, melatonin, and their role in health and disease over here at Circadiana. It's a field he actually knows about and there are lots of interesting tidbits, so check it out.
