Smoking increases risk of colon polyps

02.11.2004


Smokers can add pre-cancerous growths in the colon to the host of increased health risks they face, according to two studies presented at the 69th Annual Scientific Meeting of the American College of Gastroenterology. Researchers at Our Lady of Mercy Medical Center examined the relationship between polyps and dietary and recreational habits as well as medications in a prospective study of 157 patients with a mean age of 55 years and found smokers faced a significant risk of developing colon polyps – precancerous growths in the colon.



The researchers gathered a range of demographic and health information, including smoking history and use of herbal and nutraceutical supplements including vitamins and minerals, among other information. Participants underwent colonoscopy screening to detect polyps and colorectal cancer.

The researchers found cigarette smokers were more likely to have polyps, to have a greater number of polyps, and to have larger polyps than non-smokers. A logistic regression analysis determined a four percent increased risk of polyps for every additional year of smoking.


Interestingly, these researchers found there was a significant association between the use of vitamin C and the absence of polyps (p=0.023). In this sample, 16 patients regularly consumed vitamin C supplements at doses equal to or more than 1000 milligrams a day and none of them had polyps.

Smoking and Polyp Location for Patients over 50

At Mercy Catholic Medical Center, researchers conducted a retrospective review of patients who underwent colonoscopy. They excluded patients with a history of colon cancer or colon surgery. Their study included 177 patients with a median age of 65 years. Of the group, 57 percent had polyps located on the left side of the colon.

When analyzed for all ages, left sided polyps showed a statistically significant association with a history of smoking. Among all ages of smokers, the chance of left-sided polyps was 2.7 times higher than among non-smokers. This association was even more significant in smokers above 50 years of age. The probability of left-sided polyps was three times greater among smokers over 50 than non-smokers over fifty. The researchers point out that future studies with better quantification of smoking history are required to evaluate this association.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
