Certain dietary supplements appear to affect the development of colorectal cancer or its recurrence," according to two new studies presented during a medical conference. In one, "researchers from the US National Institute for Environmental Health Sciences found that eating a diet high in omega-3 fatty acids cut the risk of developing colorectal cancer by nearly 40 percent. In the other study, from cancer researchers in Italy, consumption of a dietary supplement containing selenium was found to reduce the chances of having polyps recur by a similar amount."
In one study, researchers from the U.S. National Institute for Environmental Health Sciences found that eating a diet high in omega-3 fatty acids cut the risk of developing colorectal cancer by nearly 40 percent. In the other study, from cancer researchers in Italy, consumption of a dietary supplement containing selenium was found to reduce the chances of having polyps recur by a similar amount.
In the selenium study, 411 people, 25 to 75 years old, who'd had one or more colorectal polyps removed took either a supplement or a placebo. The supplement, described as an antioxidant compound, contained 200 micrograms of selenomethionnine (a combination of selenium and methionnine), 30 milligrams of zinc, 6,000 international units of vitamin A, 180 milligrams of vitamin C and 30 milligrams of vitamin E.
Participants had a colonoscopy one year, three years and five years after starting the regimen.
The researchers estimated that, after 15 years, about 48 percent of those taking the supplement were free of polyps, versus about 30 percent of those not taking the supplement.
Among the white participants, those whose diets were in the highest fourth of omega-3 fatty acid consumption were 39 percent less likely to have colorectal cancer than those in the lowest fourth. However, for reasons the authors said they did not know, no association was noted between omega-3s and a reduction of colorectal cancer risk among black participants. The disease occurs at a higher rate among blacks than whites.
"Our finding clearly supports the evidence from previous experimental and clinical studies showing that long-chain omega-3 fatty acids inhibit tumor growth," said the study's lead author, Sangmi Kim, a postdoctoral fellow at the U.S. National Institute of Environmental Health Sciences in Research Triangle Park, N.C.
Kim said the research supports boosting omega-3 intake through diet or perhaps by taking an omega-3 supplement. Omega-3 fatty acids are found in fish, especially oily fish such as salmon, mackerel, herring, anchovies, sardines and tuna. Plant-based sources include flax and flaxseed oil, Brussels sprouts, soybeans and soybean oil, canola oil, spinach, walnuts and kiwi.

HOW TO LOWER PROSTATE CANCER RISK
Harvard scientists have discovered that "drinking coffee may lower the risk of developing the deadliest form of prostate cancer." In fact, "the five percent of" study participants "who drank six or more cups a day had a 60 percent lower risk of developing the advanced form of the disease than those who didn't consume any."."
A Frontiers in Cancer Prevention Research conference" also touched on the "role that exercise...could play in the fight against prostate cancer. An analysis of activity levels among 2,686 prostate cancer patients showed that men who jogged, played tennis, or participated in other comparable exercise for an average of three or more hours per week had 35% lower mortality rates than those who exercised less frequently or not at all." As for walking, those who did so "for four or more hours per week" had "overall mortality rates [that] were 23% lower than those of men who walked for fewer than 20 minutes per week."

Autism increases in the US
Almost one percent of American children had an autism spectrum disorder (ASD) in a large CDC surveillance study whose lead author called the condition a "significant public health issue."
Across 11 sites in the U.S., ASD prevalence in 2006 ranged from about one out of 80 children to one out of every 240 children, with an overall prevalence of one in 111 youngsters, according to a report by investigators from the CDC's Autism and Developmental Disorders Monitoring (ADDM) Network.
Among 10 ADDM sites that reported data in both 2002 and 2006, there was an average 57% increase in ASD prevalence. No single factor could explain the rise, researchers said. Overall ASD prevalence was 4.5 times higher in boys than in girls: about one in every 70 boys and one in every 315 girls.
From 2002 to 2006, prevalence increased 60% in boys and 48% in girls (P<0.001 for both).
The American Academy of Pediatrics has recommended that all children be screened for autism when they are 18 and 24 months old which is especially important, as early recognition and treatment improves outcomes.
ASD diagnosis was made at a slightly younger age in 2006 than in 2002, but it was still delayed to an average age of 53 months. That was so despite the fact that anywhere from 70% to 95% of children had developmental concerns noted in their records before age 3.

Cluster Headaches
Concerned about recent overdoses of radiation in CT perfusion scans, an FDA official urged imaging practitioners to go "back to basics" when they're performing the scans.
The advice comes after more than 250 patients in two states were exposed to excess radiation during CT perfusion brain scans.
"Until we get through whether we're dealing with errors that people are making (or) whether these are problems with the CT scanners themselves, we're saying go back to basics," said Jeffrey Shuren, MD, acting director of the FDA's Center for Devices and Radiological Health.
Shuren and colleagues released a set of interim recommendations while the agency continues to investigate cases of overexposure reported in California and Alabama.
They include:
• Imaging facilities should review their radiation dosing protocols for all CT perfusion studies to ensure that dosing is correct for each study.
• They should implement quality control procedures to ensure that protocols are followed and correct radiation is used.
• For each patient, technologists should check the CT scanner displays to make sure the radiation to be delivered is appropriate.
• If more than one study is performed during one session, practitioners should adjust the radiation dose so it is appropriate for each study.
The agency also urged imaging facilities to check whether any patients who underwent CT perfusion scans have received excess radiation.
"We're reminding (practitioners) of good practices that they should be employing routinely," said Charles Finder, MD, also of the agency's Center for Devices and Radiological Health.
The issue arose when the FDA was told of more than 200 cases of excess radiation delivered during CT perfusion brain scans at Cedars-Sinai Medical center in Los Angeles. (See CT Safety Warnings Follow Radiation Overdose Accident)
Since then, the agency has received reports of 14 cases at Glendale Adventist Medical Center, also in Los Angeles, as well as an undetermined number of cases at St. Joseph's Medical Center in Burbank, Calif., according to Simon Choi, PhD, also of the Center for Devices and Radiological Health.
Choi said the the agency is investigating reports in Alabama, too, but he did not give numbers or the name of the facility involved.
The agency said scanners made by two manufacturers, GE and Toshiba, are involved in the incidents.
Affected patients had redness of the skin and some hair loss, but potential long-term consequences include an increased risk of cancer and cataracts, Finder said.
The standard radiation dose for a CT perfusion scan is between 0.5 and 1.0 Gray, but it was reported that some patients at Cedars-Sinai got as much as 3.0 or 4.0 Gray.
According to a statement from the hospital, "there was a misunderstanding about an embedded default setting applied by the machine."
The recommendations apply to all CT perfusion imaging, since the methods involved are the same as for brain perfusion scans, the FDA said.
While the agency is probing cases in the two states, Shuren said, "we would not be surprised to find there are similar occurrences in other states."

Good News & Bad News
NIH Report Finds Cancer Incidence Has Declined.
A report by the NIH found that "the incidence in men of cancers of the prostate, lung, oral cavity, stomach, brain, colon and rectum has declined." However, "rates in men continue to rise for kidney/renal, liver, and esophageal cancer, as well as for leukemia, myeloma and melanoma," the agency said.
Heavy Margarines May Be Increasing Their Risk Of A Painful Inflammatory Bowel Disease,
People who eat lots of red meat, cook with certain types of oil, and use some kinds of polyunsaturated fatty acid (PUFA)-heavy margarines may be increasing their risk of a painful inflammatory bowel disease, a study in more than 200,000 Europeans shows.
These foods are high in linoleic acid and the study have found that people who were the heaviest consumers of this omega-6 PUFA were more than twice as likely to develop ulcerative colitis as those who consumed the least.
But eating more eicosapentaenoic acid, an omega-3 fatty acid found in fish and fish oils, was associated with a lower risk of the disease.
To investigate the role of fatty acids and ulcerative colitis, a life-long disease characterized by inflammation of the lining of the large intestine, investigators analyzed the problem. Their analysis included 203,193 men and women 30 to 74 years old. During follow-up, which ranged from about 2 to 11 years, 126 people developed ulcerative colitis.
People in the top quartile of linoleic acid intake (they were consuming around 13 to 38 grams a day) were 2.5 times more likely to have developed the disease than people who consumed the least, about 2 to 8 grams daily.
While a Western-style, red-meat-heavy diet is high in this fatty acid and low in omega-3s, a more Mediterranean style eating pattern -- with plenty of fruits and vegetables, fish, and nut oils -- would be low in linoleic acid and high in omega-3.
It is estimated that if omega-3s do help prevent ulcerative colitis, eating a couple of servings of fish a week would probably be protective.

High coffee, tea intake may reduce chances of developing type 2 diabetes.
According to a study spublished in the Archives of Internal Medicine, "drinking four cups of coffee, decaf, or tea daily can reduce the chances of getting type 2 diabetes by about 25 percent to 35 percent." Harvard University "researchers reviewed 18 studies of almost 500,000 people" and discovered that "for each cup of coffee people drank, their likelihood of getting diabetes dropped by seven percent."
"Even better results were found for bigger coffee and tea consumers -- drinking three to four cups a day was associated with about a 25% reduced diabetes risk, compared with those who drank between none and two cups day.. In addition, investigators found "positive results with decaf coffee and tea." Specifically, those "who drank more than three to four cups of decaf a day had about a one-third lower risk than those who didn't drink any," while "tea drinkers who consumed more than three to four cups a day had about a one-fifth lower diabetes risk than non-tea drinkers."

Osteoporosis prevention and nutrition
Although calcium and vitamin D have been the primary focus of nutritional prevention of osteoporosis, recent research has clarified the importance of several additional nutrients and food constituents. Further, results of calcium and vitamin D supplementation trials have been inconsistent, suggesting that reliance on this intervention may be inadequate. In addition to dairy, fruit and vegetable intake has emerged as an important modifiable protective factor for bone health. Several nutrients, including magnesium, potassium, vitamin C, vitamin K, several B vitamins, and carotenoids, have been shown to be more important than previously realized.
Rather than having a negative effect on bone, protein intake appears to benefit bone status, particularly in older adults. Regular intake of cola beverages shows negative effects and moderate alcohol intake shows positive effects on bone, particularly in older women. Current research on diet and bone status supports encouragement of balanced diets with plenty of fruit and vegetables, adequate dairy and other protein foods, and limitation of foods with low nutrient density.
