Study: Cancer risk increased by alcohol

(UPI) People who drink more than a pint of beer a day face a substantially higher risk of certain cancers, a European study suggests…
Previous studies have found links between alcohol consumption and cancers of the esophagus, liver, bowel and breast.
A chemical that can damage DNA is produced when alcohol is broken down in the body, increasing cancer risks, researchers say.

More evidence painkillers lower colon cancer risk

(Reuters Health) A new study adds to growing evidence that regular use of painkillers like aspirin or ibuprofen may reduce a person's risk of developing colon or rectal cancers - sometimes by as much as 50 percent.
This latest report also shows that people with a family history of colon cancer - who are therefore at higher risk for the disease - also benefit from the pain relievers.

Naproxen Reduces Tumors in a Mouse Model of Colon Cancer, Researchers Report

(Science Daily) Numerous studies show that non-steroidal anti-inflammatory drugs (NSAIDs) reduce the risk of colon cancer. However, animal studies testing the NSAID naproxen or its derivative, NO-naproxen, have focused primarily on chemically-induced tumor formation. Now, researchers at Fox Chase Cancer Center find that naproxen and NO-naproxen reduce tumor formation in a strain of mutant mice that spontaneously develop colon tumors. The data also suggest that naproxen blocks a gatekeeper step that initiates tumor formation…
"There is a major effect on the very small lesions, about a 90% reduction in the mutant mice treated with naproxen compared with control animals," says [Margie Clapper, PhD]. "That tells us this drug may be very appropriate for intervening early in people, far in advance of the development of large tumors. We might be able to have a significant impact on the very early and small lesions, thus reducing the morbidity associated with the disease."

Reduce Colon Cancer Risk 65 Percent with This Meal

(RealAge.com) You could drop your risk of colon cancer by as much as 65 percent with this simple and delicious diet switch. Trade that meat-and-potato kabob for a fish-and-vegetable one…
A diet that's bursting with fruit, vegetables, whole-grains, and healthy protein choices like fish rather than meat is smart for a variety of health reasons. But it appears that the good things in this diet -- like fiber, antioxidants, vitamins, and minerals -- may work synergistically to keep the colon healthy and free of cancer. For good measure, add beans and low-fat dairy -- two more diet choices that appear to be an important part of a healthy-colon diet.

Protect Your Pancreas with This Vegetable

(RealAge.com) Make pancreatic cancer the scariest disease you never got by eating more of this bumpy green veggie: broccoli.
Seems that flavonol-rich diets could reduce your risk of pancreatic cancer by up to 23 percent, according to a recent study…
Flavonols are … found not only in broccoli but also in lots of other fruits and veggies, like apples, onions, and kale. And these compounds help fight cancer on many fronts. First, they ramp up your body's detox machinery, purging dangerous carcinogens from your system. Next, flavonols help prevent cancer cells from growing and dividing. And as if that weren't enough, flavonols encourage cancer cells to self-destruct, too.

Vegetarian diet linked to lower cataract risk

(Reuters Health) Eating less meat and more vegetables is tied to a lower risk of cataracts, a British study says…
The results translated to a 30 to 40 percent lower cataract risk among vegetarians and vegans compared with the biggest meat eaters.
"People who don't eat meat have a significantly lower risk of developing cataracts," said Naomi Allen, an epidemiologist at the UK's University of Oxford who coauthored the study.

Very high caffeine intake linked to leaky bladder

(Reuters Health) Women who down a lot of caffeinated drinks each day may have a slightly increased risk of developing urinary incontinence, a new study suggests. The results add to conflicting evidence on whether caffeine worsens a common condition…
Compared with women who got the least caffeine, those with the highest intake were 19 percent more likely to develop frequent problems with bladder control (at least once a week).
The study found no increased risk among women consuming 299 milligrams of caffeine - the equivalent of about three cups of coffee - or less per day.

Discovery Points to New Obesity and Diabetes Drugs

(Science Daily) New research by scientists at The Scripps Research Institute and collaborating institutions has identified a key regulator of fat cell development that may provide a target for obesity and diabetes drugs.
In a paper…, the scientists describe a protein called TLE3 that acts as a dual switch to turn on signals that stimulate fat cell formation and turn off those that keep fat cells from developing. TLE3 works in partnership with a protein that is already the target of several diabetes drugs, but their use has been plagued by serious side effects.
"There is definitely a need for alternative drug targets," said [the researchers]. "Our goal is to understand how fat cells form so that we can develop better treatments for obesity and related disorders."

Blood Protein Levels May Predict Risk of a Cardiovascular Event

(Science Daily) Increased levels of a protein that helps regulate the body's blood pressure may also predict a major cardiovascular event in high-risk patients, according to a study… Measuring the amount of the protein, known as plasma renin activity (PRA), in the blood stream may give doctors another tool to assess a patient's risk and help prevent a heart attack or stroke…
"This study makes a strong case for further study of PRA and its association with cardiovascular death," explains [senior author Dr. Subodh] Verma. "The next step will be to move into larger trials with PRA therapies and study whether or not this impacts the cardiovascular death rate. This could be a big step forward in our battle against heart disease."

Medicare's Drug Coverage Gap to Shrink Away Under Health Care Reform

(HealthDay News) Starting this year, Medicare Part D's widely despised "donut hole" -- the gap in drug cost coverage enrollees encounter when they reach a certain spending threshold -- will start to disappear, one result of the health care reform package enacted last year, experts say.
In 2010, the donut hole kicked in after a beneficiary had incurred $2,530 in annual drug spending. They were then responsible for every dollar incurred up until $6,137 in spending, at which point "catastrophic" coverage kicked in.
However, experts say that under the new Affordable Care Act, this coverage gap will shrink considerably beginning this year, and completely disappear by the year 2020. But the process will be a step-wise transition -- and that doesn't include the possibility of Republican efforts to curtail or even dismantle the new legislation.

Healthy Eating Leads to Longer Life

(Andrew Weil, M.D.) The idea that eating a healthy diet extends lifespan makes sense, but new research is revealing even more about the link between longevity and specific diets. A study team from the University of Maryland evaluated the diets of more than 2,500 men and women in the U.S. age 70 to 79. Not surprisingly, they found eating habits that emphasized fruits, vegetables whole grains, poultry, fish and limited amounts of meat, fried foods, sweets and high-calorie drinks were correlated with higher survival rates over a 10-year span. The individuals who ate this way also smoked less and were more active than those in other groups…
My take? The best prescription for healthy aging is an anti-inflammatory diet, designed to reduce the chronic low-level inflammation that contributes to heart disease, cancer, Alzheimer's and Parkinson’s diseases, type 2 diabetes, and many other diseases.

Warning Labels Better Than a Fat Tax, Study Shows

(Science Daily) Warning labels on junk food would be more effective than a "fat" tax for deterring overweight people from making unhealthy purchases, a new University of Alberta study has found…
"The consumers who heeded the label didn't care about the price, but responded to the warning and were much less likely to buy the snack," said Sean Cash…, who led the study.
The researchers theorize that warning labels pack a bigger behavioural punch because they are far more noticeable than the price differences that would result from snack taxes. Therefore, including warning labels on unhealthy foods would be a better option than a fat tax, which has already been implemented in varying degrees in the United States, and is being considered for Canada.

Could Stomach 'Pacemaker' Be New Weight-Loss Tool?

(HealthDay News) The device, not yet approved for use in the United States, is dubbed "abiliti" by its London-based maker, IntraPace. According to the company, the device is implanted in the stomach during a one-hour laparoscopic procedure via small insertions in the abdominal wall.
Once in place, the device uses its food-detection sensor to sense whenever a patient eats or drinks. This prompts it to emit low energy electrical pulses to nerves that trigger a feeling of rapid fullness…
An activity sensor also tracks the patient's food intake and physical exertion levels, sending that information automatically to a computer so patients and doctors can easily monitor (and adjust) eating and exercise habits.
Community: For addicts, it’s not a question of feeling full. If you still have any doubts that people can be addicted to food, take a look at a new series on OWN, “Addicted to Food”. The premiere was this week, but I’m sure there will be repeats.

Substance in tangerines fights obesity and protects against heart disease

(University of Western Ontario) New research from The University of Western Ontario has discovered a substance in tangerines not only prevents obesity, but also offers protection against type 2 diabetes, and even atherosclerosis, the underlying disease responsible for most heart attacks and strokes. Murray Huff [and a colleague] studied the effects of a flavonoid in tangerines called Nobiletin…
[M]ice were fed a "western" diet high in fats and simple sugars. One group became obese and showed all the signs associated with metabolic syndrome: elevated cholesterol and triglycerides, high blood levels of insulin and glucose, and a fatty liver. These metabolic abnormalities greatly increase the risk of cardiovascular disease and type 2 diabetes.
The second group of mice, fed the exact same diet but with Nobiletin added, experienced no elevation in their levels of cholesterol, triglycerides, insulin or glucose, and gained weight normally…
"The Nobiletin-treated mice were basically protected from obesity," says Huff… "And in longer-term studies, Nobiletin also protected these animals from atherosclerosis, the buildup of plaque in arteries, which can lead to a heart attack or stroke. This study really paves the way for future studies to see if this is a suitable treatment for metabolic syndrome and related conditions in people."
Community: I found two supplements that claim to contain Nobiletin: Sytrinol and PureWay C. They’re probably not available at your local grocery store. I buy my supplements online, anyway. They’re much cheaper.

Not only can this save you time, but it can also save you money — especially when buying meat. Just follow these tips for thawing frozen food, since leaving it out to defrost all day is dangerous.
The key to defrosting foods is to keep them at a safe temperature during the thawing process. As soon as food begins to defrost and become warmer than 40°F, bacteria can start to grow and spread. That’s why food should never be thawed and kept on the kitchen counter or placed in warm water.

Can Diabetes or Lipid-Lowering Medications Treat Addiction?

(Science Daily) Thiazolidinediones (TZDs) are a class of medications that are commonly prescribed to treat type-2 diabetes, while fibrates are a structurally-related class of medications that are prescribed to modulate lipid levels in both diabetic and non-diabetic patients to help reduce the risk of cardiovascular disease. These drugs work by binding to peroxisome proliferator-activated receptors (PPARs)…
Another effect of TZDs and fibrates is to raise leptin levels, an effect that may reduce appetite. Recent studies also suggest that PPARs are expressed in the central nervous system, particularly in brain regions implicated in reward.
Two papers … now suggest that drugs that stimulate two different subclasses of PPARs … may play roles in the treatment of nicotine and alcohol addiction …
It is important to note that these exciting initial findings are only the beginning steps in a line of research that will need to be undertaken before TZDs or fibrates could be used in a clinical setting to treat people with addictions.

Scientists Develop New Technology for Stroke Rehabilitation

(Science Daily) Devices which could be used to rehabilitate the arms and hands of people who have experienced a stroke have been developed by researchers at the University of Southampton…
Three tactile devices were developed and tested on patients who had had a stroke and on healthy participants. The devices were: a 'vibration' tactile device, which users felt provided a good indication of touch but did not really feel as if they were holding anything; a 'motor-driven squeezer' device, which users said felt like they were holding something, a bit like catching a ball; and a 'shape memory alloy' device which has thermal properties and creates a sensation like picking up a cup of tea.
Dr [Geoff] Merrett adds: "We now have a number of technologies, which we can use to develop sensation. This technology can be used on its own as a stand-alone system to help with sensory rehabilitation or it could be used alongside existing health technologies such as rehabilitation robots or gaming technologies which help patient rehabilitation."

More people die of hatred than other cause

(UPI) More people have died because of human hatred than from any other human cause, a U.S. professor says.
"Yet we still do not know enough about how hatred works and how to prevent and combat it," John Shuford, director of the Gonzaga University Institute for Hate Studies, in Spokane, Wash., said in a statement.
The Gonzaga University Institute for Hate Studies is hosting the Second International Conference on Hate Studies Wednesday through Saturday in Spokane.
The conference purpose is to foster better understanding of the nature of hatred, develop more effective models and approaches for combating it and consider the implications for practice across many fields, Shuford said.
Community: There seems to be in humans some built-in fear of the “other”, or anyone outside the clan or tribe, but according to Robert Sapolsky, writing in Foreign Affairs in 2006, “Humans may be hard-wired to get edgy around the Other, but our views on who falls into that category are decidedly malleable.” So there’s hope that we can overcome hatred and its consequences. But we have to have the will to do it.
In the current climate, some people are promoting hatred, for their own political benefit. Sadly, we all lose when they succeed.

Chimp, Bonobo Study Sheds Light on the Social Brain

(Science Daily) It's been a puzzle why our two closest living primate relatives, chimpanzees and bonobos, have widely different social traits, despite belonging to the same genus. Now, a comparative analysis of their brains shows neuroanatomical differences that may be responsible for these behaviors, from the aggression more typical of chimpanzees to the social tolerance of bonobos.
"What's remarkable is that the data appears to match what we know about the human brain and behavior," says Emory anthropologist James Rilling, who led the analysis. "The neural circuitry that mediates anxiety, empathy and the inhibition of aggression in humans is better developed in bonobos than in chimpanzees."
Community: We are more closely related to bonobos than to chimpanzees, though strongly related to both. This research adds to knowledge about the genetic bases of some of our behaviors. I’d write a book about these built-in drives and how they might benefit us all, if I could ever find a publisher.
