Sleep Apnea related to cancer - medpage today

Not that I believe everything I read.

"Moderate-to-severe sleep apnea is independently associated with a large increased risk of all-cause mortality, incident stroke, and cancer incidence and mortality in this community-based sample." from http://www.aasmnet.org/jcsm/ViewAbstract.aspx?pid=29425

What is unclear to me from the abstract is if the patents studied were being treated with CPAP or other devices.

This is so typical - they never say! However I believe they're referring to untreated people... I just wrote a note to the first researcher (Dr. Marshall) of the paper and asked if subjects were being treated - and if and when he answers, will let all of you know.

Slow news day! Sleep Apnea causes everything that happens to humans, even acid rain and global warming and the next ice age.

The good thing, the people who write these kind of articles, have paying jobs (maybe), so they may pay taxes, even if they don't create anything useful.

I use my personal off switch, when articles are published, I don't need poor science or poorly done ones clouding up my thinking. Every idea they come up with is reversed every 5 to 10 years, getting excited about articles is as productive as spitting into the wind. Jim

Ya know... I think this is actually the first time I've ever agreed with Goofproof. Now drinking 4/5 cups of coffee is supposed to ward off dementia - three years ago I remember reading that more than one cup was going to kill you.

On one hand I could understand; disrupting the time when the body repairs itself, influencing cancer rates.

On the other, I can't remember if I'm supposed to eat eggs this decade or not, or have two drinks a day or none, or stay in the sun for the Vit D or stay out for the skin cancer risk.....

Just hold off a ex-college student, that passed making "D"'s, will write more articles, telling you what you need to know to live a healthy life. Maybe he didn't get through college, smoking dope and emptying all the kegs in the dorms. Jim

But maybe he did and you are putting your life in his hands.

Hi all - here's my orig. note to Dr. Marshall, his answer and my reply...

Dr. Marshall -
"As a long time member of what I believe is likely the best, most comprehensive and helpful forum on sleep apnea and Cpap on the 'net, and after reading the abstract of your paper "Sleep Apnea and 20-Year Follow-Up for All-Cause Mortality, Stroke, and Cancer Incidence and Mortality in the Busselton Health Study Cohort", I have a question for yourself (and all other published researchers of apnea).

Why do none of the authors ever specify whether the trial subjects were already on Cpap or not? It's beyond frustrating to want to learn more, and certainly very interesting to read similar studies, but such a basic part of the information never seems to be given. I have assumed that in fact subjects were not treated, but assumptions are not a great way to learn much.

Thanks for your time. Your answer, if you do provide one, will be shared (unless you specify otherwise) with forum members of Cpaptalk.com."
_______________

"Thanks for your interest in our paper.

The people in this study are not trial subjects. They are members of a community-based cohort study. The study is about the effects of Sleep Apnea, not its treatment with CPAP. That's why CPAP is not mentioned in the 250 word abstract. We are strictly limited to a 250 word limit in these so we try not to mention things we didn't investigate there. It's not that we're not interested in treatment effects but we do that in different types of studies (clinical trials).

The full manuscript does talk about the fact that we don't believe anybody was treated. We did send letters to all the people we thought might benefit from treatment. But none of them presented to Dr Cullen who set up a clinic in the town next to Busselton to help them.

Kind Regards, Nat Marshall

"Thank you so much for your quick reply - I do understand about the limits of abstracts, and also your focus. It's only that in our eagerness to learn more, and coming across study after study without the single word 'untreated' (or 'treated') as one descriptor of participants (a major clarification in our eyes) we can't take away much from the information, as we see it as all important in appreciating the results. I'm sorry to have 'picked on' your paper - possibly because I did find it recent, relevant otherwise and well done, but good luck with your work and thanks again for replying."

........That's it...
