Obsession with "Overvalued Idea" Can Be Source of Violence

(HealthDay News) Any time there's a violent tragedy -- the killing of at least 86 people at a youth camp in Norway, the shootings of a congresswoman and others in Tucson, the Virginia Tech massacre -- one question seems to ring clearer than others: Why didn't someone notice beforehand that the suspect might be disturbed and capable of committing deadly violence?...
People prone to mass violence often have fallen victim to an "overvalued idea," a psychiatric term for an unreasonable belief over which the person has become obsessed, [psychiatry professor Dr. Thomas] Wise said.
Overvalued ideas are not delusions, in that people with overvalued ideas are not completely and irrationally fixed in their beliefs despite any evidence provided them, he explained. The irony is that people suffering from delusions and clearly mentally ill, he said, are less likely to commit violence than people teetering on the brink of obsession who are not technically suffering from a mental disorder.
"People who have overvalued ideas often act on them," Wise said. "People with delusions do not."
Community: The level of vitriol has been rising for years, so that now it’s acceptable on the right to threaten to kill liberals, simply for what we believe. It’s no wonder that some of the adherents grab a gun and start shooting. Jon Stewart’s opening segment (video) from Wednesday night shows the hypocrisy better than anything I’ve seen.

Sept. 11, 2001, psychological effects last

(UPI) Following the attacks on Sept. 11, 2001, research has broadened the understanding of post-traumatic stress disorder, U.S. researchers say.
A special issue of the American Psychologist includes a dozen peer-reviewed articles, which examine the social, political and psychological impacts of the nation's worst terrorist attacks.
The issue illustrates how psychology is helping people understand and cope with Sept. 11, 2001's, enduring impacts and explores how psychological science helped people understand the roots of terrorism and how to prevent further attacks.

Generosity built into human nature

(UPI) Generosity is likely more than a result of social pressure and may be built in to human nature, U.S. researchers suggest…
"When past researchers carefully measured people's choices, they found that people all over the world were more generous than the reigning theories of economics and biology predicted they should be," [Max M.] Krasnow says in a statement. "Even when people believe the interaction to be one-time only, they are often generous to the person they are interacting with."
The study … shows generosity emerges naturally from the evolution of cooperation.
Community: As I’ve been saying. This study gives us more proof that the political right’s praise of individual selfishness is maladaptive and, if not countered, will have dire consequences for the human race.

Worrying Can Impact Interpersonal Relationships, Study Finds

(Science Daily) Most people worry from time to time. A new research study, led by a Case Western Reserve University faculty member in psychology, also shows that worrying can be so intrusive and obsessive that it interferes in the person's life and endangers the health of social relationships.
These people suffer from what's called generalized anxiety disorder (GAD), says Case Western Reserve psychologist Amy Przeworski…
She suggests that therapies to treat GAD should target both the worry and the related interpersonal problems.
Most treatments for GAD rely on cognitive behavioral therapy, a treatment that is usually successful for about 60 percent of people, a percentage considered successful in therapy. However, one way to improve therapy for worriers may be to integrate techniques that target the interpersonal relationship problems.

Women take different risks than men

(UPI) Conventional wisdom holds that women take fewer risks than men but U.S. researchers say women take different kinds of risks than men, such as social risks…
"Men are willing to take more risks in finances. But women take more social risks -- a category that includes things like starting a new career in your mid-30s or speaking your mind about an unpopular issue in a meeting at work."

Half of men say they'll drop a fat partner

(UPI) Almost 48 percent of American men say they would dump their partner is she gained weight, an Ask.men.com survey indicates…
The entire survey results are at: www.askmen.com/specials/great_male_survey and at www.askmen.com/specials/great_female_survey.
Community: Since more than 60 percent of Americans are overweight or obese, that means some of the men in that 48 percent (more than 60 percent?) are overweight themselves, but don’t want an overweight partner. Jerks!

How To: Cooking with Wine
Want to add flavor and reduce the amount of fat you use when cooking? Try wine. Red or white, wine offers a unique character to entrees, and can also help to cut down on the amount of fat you use - in some recipes, you can substitute wine for part or all of the specified quantity of oil. I like to use wine when sautéing or pan-frying, as it works well in place of the oil that it would typically require.

A Sweet Snack That Lowers Cholesterol

(RealAge.com) Okay, it's no news flash that blueberries are nutritious. But here's something you probably didn't know: They may help keep your arteries from clogging.
In an animal study, researchers discovered that blueberries could have the power to cut LDL cholesterol levels almost in half.
In the study, scientists noted that the blueberry health benefits persisted even when the test subjects were fed a high-fat diet. At the end of the 3-week study period, the blueberry-supplemented diet had reduced LDL (the bad stuff) cholesterol by as much as 44 percent. And total cholesterol had dipped 27 percent. Pretty impressive numbers. More study is needed to see whether the same benefits would hold true in humans, but researchers are optimistic.

Grapes may protect against sun radiation

(UPI) Substances in grapes can reduce the amount of cell damage caused in skin exposed to the sun's ultraviolet radiation, researchers in Spain say.
Marta Cascante … and colleagues at the Spanish National Research Council say UV rays act on the skin by activating "reactive oxygen species," and these compounds in turn oxidize macromolecules such as lipids and DNA, stimulating certain reactions and enzymes … that cause cell death.
The researchers showed some polyphenolic substances extracted from grapes, flavonoids, can reduce the formation of reactive oxygen species in human epidermis cells that have been exposed to long-wave ultraviolet A and medium-wave ultraviolet B radiation.
Community: Resveratrol is one of the most studied of the grape polyphenols. It’s available as a food supplement.

The Paleo Diet: Caveman Cure-All or Unhealthy Fad?

(Alesh Houdek, The Atlantic) The idea of the Paleo diet has been around for decades, but it's really taken off over the last couple of years, with a slew of books, blogs, and a prominent podcast espousing its virtues. And no wonder—it has a compelling sales pitch. It's based on the idea that while humans have been eating for approximately 200,000 years, we've been farming for only about the last 10,000 or so. Farming introduced easily produced grains into our society, and bread, pasta, and other starch-heavy and processed foods into our diets. Evolution is too slow, the story goes, for us to have adapted to this new diet. So these "new" foods are responsible for many specific health problems we encounter, as well as a general feeling of un-wellness that most of us unwittingly life with. By returning to the diet of our hunter-gatherer ancestors, the proponents of Paleo claim, we can restore our happiness, health, and waistlines.
After hearing one too many first-person accounts of startling and positive changes in people's lives after going Paleo (and despite Michael Pollan's warnings about fad diets), I had to give it a shot. And you know what? It's been pretty great. After a few weeks, I've lost weight, I feel better, and the two-hour-plus sluggish period that used to follow lunch just about every day is gone. That's while eating sort of like a pig—meat, vegetables, nuts, eggs, fish, all cooked with butter and scarfed down with gleeful self-contentment. I get hungry less often, and when I do it's a different sort of hunger; not nagging and brain-debilitating, but more natural-feeling and subtle, almost healthy…
But "going Paleo" is much more than a diet. The approach has something to say about exercise, footwear, and community. But a key hint of what's happening here may be in the Paleo treatment of alcohol. It is, of course, completely prohibited. Yet beyond that it comes up infrequently and receives little attention. It's as though anyone into Paleo had quit drinking long before anyway and never looked back. In other words, this is a lifestyle that's observed by a very particular type of person. Someone with will-power and a concern with their body that is beyond the pale for the majority of people, and who's probably been successful at any number of approaches to eating, exercise, and overall lifestyle. There's no doubt that the Paleo approach is a powerful meme, but as advice for regular people it's just not very practical.
Community: Well, you don’t have to “go Paleo” to use some of its ideas to your benefit. I’m a firm believer in “take what you want and leave the rest.” I, like this author, have experienced less hunger and less biting hunger from eating a healthier diet. I also no longer have that don’t-want-to-get-up-off-the-couch feeling.

Caution Urged in Intensive Treatment of Type 2 Diabetes

(HealthDay News) Intensive glucose-lowering treatment for people with type 2 diabetes doesn't reduce the risk of cardiovascular-related death and doctors need to be cautious about prescribing this type of treatment, a new study suggests.
Patients with type 2 diabetes are at increased risk for cardiovascular disease. Intensive glucose-lowering treatment is widely used for these patients even though previous research hasn't shown any clear benefits, the researchers pointed out.

Implantable Device May Ease Tough-to-Treat Hypertension

(HealthDay News) For people with high blood pressure that medication can't control, a new implantable device shows promise, researchers report.
The device, surgically placed just below the collarbone, sends a four- to six-volt electrical jolt to the carotid arteries. This is said to lower blood pressure through a process known as baroreflex activation therapy.
The device might help tackle a growing problem, said the lead author of the study, which was funded by CVRx Inc., the device's maker.

Novel Blood-Cleaning Procedure Used for Kidney Transplant

(Science Daily) St. Michael's Hospital is the [first hospital] in North America to use a novel blood-cleaning procedure for a kidney patient that will allow him to receive a transplant from a donor with a different blood type.
Transplants involving a donor and recipient with different blood types are rare. Most people have natural antibodies in their blood that would cause their immune system to reject an organ from someone with a different blood type.
The procedure used … is called plasmapheresis and is similar to kidney dialysis, which removes waste products from the blood…
The procedure may need to be repeated a few times to get rid of all the antibodies. The patient will also receive medications to prevent his immune system from making more antibodies and attacking the transplanted kidney.

Scientists Design Nano-Sized Drug Transporter to Fight Disease

(Science Daily) Scientists seeking to improve cancer treatments have created a tiny drug transporter that maximizes its ability to silence damaging genes by finding the equivalent of an expressway into a target cell. The transporter, called a nanocarrier, is a lipid-based structure containing a piece of RNA. Lipids are fatty molecules that help maintain the structure of cell membranes.
The RNA segment encased in the carrier sets off a process to silence genes, rendering the genes unable to produce proteins that lead to disease or other health problems.
Though the main component of the carrier resembles existing and previously studied transporters, Ohio State University scientists have attached specific helper molecules to the carrier's surface that their research suggests can enhance the transporter's effectiveness.

Getting 50-Year-Old Americans as Healthy as Europeans Could Save Billions

(Science Daily) Forty years ago, Americans could expect to live slightly longer than Europeans. This has since reversed: in spite of similar levels of economic development, Americans now live about a year-and-a-half less, on average, than their Western European counterparts, and also less than people in most other developed nations…
[R]esearchers … find that health in middle-age -- around the age of 50 -- is overwhelmingly the main contributor to disparities in life expectancy between Americans and Europeans…
Improving American health during middle age in the future to increase life expectancy would increase later-life pension benefits. But this expenditure would be offset by a significant decrease in health care costs -- at least $17,791 per person, the researchers estimate.
Though the transition to better health initially raises expenditures, the researchers estimate that by 2050 health care savings from gradual middle-age health improvements could total more than $1.1 trillion.
Community: As usual, it’s left to me to point out the huge reduction in suffering that would be the result of an effort like this.

Building Muscle May Reduce Diabetes Risk, Study Says

(HealthDay News) Increasing your muscle mass can help lower your risk for type 2 diabetes, a new study suggests…
[It]  found that for each 10 percent increase in the skeletal muscle index (SMI) -- the ratio of muscle mass to total body weight -- there was an 11 percent reduction in insulin resistance, a precursor to diabetes.
There was also a 12 percent reduction in pre-diabetes, a condition characterized by higher-than-normal blood sugar levels, said the researchers…
"Our findings suggest that beyond focusing on losing weight to improve metabolic health, there may be a role for maintaining fitness and building muscle mass," Dr. Preethi Srikanthan … said.

Could Fat Substitutes Make You Fat?

(RealAge.com) Sounds like a miracle -- fatty potato chips made with a fat substitute that doesn't go directly to your hips.
But a new study suggests fat substitutes could have an unforeseen downside: They might make the numbers on your bathroom scale climb higher, not lower.
In a laboratory experiment involving animals on high-fat diets, researchers noticed that the group given potato chips made with a fat substitute actually gained the most weight and developed the most fatty tissue over a 28-day period. The reason? Scientists think that when something fatty is tasted, it triggers the brain to prepare the body for a large amount of calories. When the body doesn't get those calories, the systems that regulate food intake become confused, which can result in overeating and weight gain. The study used an animal model and more research is needed to see whether the same result occurs in people, but the scientists note that there are some similarities between humans and certain animals when it comes to appetite control.

Americans cut back on sugar-sweetened soda: survey

(Reuters Health) Americans downed nearly a quarter less added sugar in 2008 than they did nine years earlier, a new report concludes.
The drop is largely due to a decrease in the amount of sugar-sweetened soda that people drank.
"We were surprised to see that there was a substantial reduction over the years," said Dr. Jean Welsh, a researcher at Emory University in Atlanta and the lead author of the report.
Although the reasons for the dip are still murky, she said a big push by the government and private organizations to alert consumers to the potential health hazards of sugar -- obesity in particular -- might have played a role.

Salt Appetite Is Linked to Drug Addiction, Research Finds

(Science Daily) A team of Duke University Medical Center and Australian scientists has found that addictive drugs may have hijacked the same nerve cells and connections in the brain that serve a powerful, ancient instinct: the appetite for salt…
"We were surprised and gratified to see that blocking addiction-related pathways could powerfully interfere with sodium appetite," said co-lead author Wolfgang Liedtke, M.D., Ph.D… "Our findings have profound and far-reaching medical implications, and could lead to a new understanding of addictions and the detrimental consequences when obesity-generating foods are overloaded with sodium."...
Deeply embedded pathways of an ancient instinct may explain why addiction treatment with the chief objective of abstinence is so difficult, said [co-lead author Professor Derek] Denton. Liedtke said that this might be relevant given the appreciable success of maintenance approaches that don't involve abstinence, like replacing heroin with methadone and cigarettes with nicotine gum or patches.
"The work opens new pathways of experimental approach to addiction," Denton said.

Women who eat lots of fiber have less breast cancer

(Reuters Health) - A fresh look at the medical evidence shows women who eat more fiber are less likely to get breast cancer.
Chinese researchers found those who ate the most of the healthy plant components were 11 percent less likely to develop breast cancer than women who ate the least.
Their findings don't prove fiber itself lowers cancer risk, however, because women who consume a lot of it might be healthier overall than those who don't…
According to the Chinese researchers, people who eat high-fiber diets have lower levels of estrogen, which is a risk factor for breast tumors.

Breast Density Tied to Specific Types of Breast Cancer, Study Suggests

(Science Daily) Women with breasts that appear dense on mammograms are at a higher risk of breast cancer and their tumors are more likely to have certain aggressive characteristics than women with less dense breasts, according to a study…
The researchers found, as expected, that the risk of breast cancer increased progressively with increasing breast density. The associations were stronger for larger tumors than for smaller tumors; for high-grade than for low-grade tumors; and for estrogen receptor-negative than for estrogen receptor-positive tumors…
 "Given that the magnitude of the association with breast density is strong across all breast cancer subtypes and particularly for ER-negative disease, breast density should be included in risk prediction models across tumor subtypes," they write.

New Cancer Treatment? Universal Donor Immune Cells

(Science Daily) One of the latest attempts to boost the body's defenses against cancer is called adoptive cell transfer, in which patients receive a therapeutic injection of their own immune cells. This therapy, currently tested in early clinical trials for melanoma and neuroblastoma, has its limitations: Removing immune cells from a patient and growing them outside the body for future re-injection is extremely expensive and not always technically feasible.
Weizmann Institute scientists have now tested in mice a new form of adoptive cell transfer, which overcomes these limitations while enhancing the tumor-fighting ability of the transferred cells…
The new approach should be more readily applicable than existing adoptive cell transfer treatments because it relies on a donor pool of immune T cells that can be prepared in advance, rather than on the patient's own cells. Moreover, using a method pioneered by Prof. [Zelig] Eshhar more than two decades ago, these T cells are outfitted with receptors that specifically seek out and identify the tumor, thereby promoting its destruction.

Exercise Has Numerous Beneficial Effects on Brain

(Science Daily) It's no secret that exercise has numerous beneficial effects on the body. However, a bevy of recent research suggests that these positive effects also extend to the brain, influencing cognition.
In a new review article highlighting the results of more than a hundred recent human and animal studies on this topic, Michelle W. Voss, of the University of Illinois at Urbana-Champaign, and her colleagues show that both aerobic exercise and strength training play a vital role in maintaining brain and cognitive health throughout life. However, they also suggest that many unanswered questions remain in the field of exercise neuroscience -- including how various aspects of exercise influence brain physiology and function and how human and animal studies relate to each other -- and issue the call for further research to fill in these gaps…
"It is increasingly prevalent in the print media, television, and the Internet to be bombarded with advertisements for products and programs to enhance mental and physical health in a relatively painless fashion through miracle elixirs, computer-based training, or gaming programs, or brief exercise programs," the authors say. "Although there is little convincing scientific evidence for such claims, there have been some promising developments in the scientific literature with regard to physical activity and exercise effects on cognitive and brain health."

Essential Summer Workout Gear

(SouthBeachDiet.com) Summer is the best time to take your fitness to the next level. But before you head out into the heat and sun, it’s important to make sure you have the proper workout gear. Wearing the right clothing and sneakers will help keep you cool and safe from the elements — and it will also reduce your risk of injury. When you’re working out in high temperatures, you lose electrolytes quicker and can become dehydrated, so be sure to also keep a water bottle at your side and take sips often. Check out our list of essential summer exercise gear:
1.    Sunglasses… Protect your eyes with a pair of sporty sunglasses. A good pair will reduce your exposure to ultraviolet (UV) rays, cut down on glare, and shield the sensitive, delicate skin under your eyes from sun damage and wrinkles. Be sure to purchase sunglasses that filter out 99-100 percent of the UV rays…
2.    Sunscreen. You should always wear sunscreen to protect your skin from the sun — even when it’s overcast… [S]ome experts recommend that people of all skin tones use a sunscreen with an SPF of 30 or higher. The FDA recently issued new regulations on sunscreen labeling and claims. All sunscreen products must protect equally against UVB and UVA rays, offering “broad spectrum” protection…
3.    Hat. Visors, baseball caps, and wide-brim hats do double duty, both protecting your eyes from the sun and keeping sweat and hair away from your face. Mesh exercise hats are a good choice because they allow air circulation, while offering protection. Exercise headbands and sweatbands are a good way to keep sweat from becoming a nuisance.
4.    Light clothing. The clothes you choose to work out in should provide you with comfort and coverage, while still being lightweight and breathable…
5.    Lightweight sneakers. Walking shoes made with breathable mesh are your best bet.
Community: I don’t spend a lot of money on this stuff, though. Sometimes the thought of a lot of expense can keep people from doing what’s best for their health.

If the athletic shoe fits

(Reuters Life!) Call them sneakers, trainers, athletic shoes or runners, sizing up the embarrassment of rubber-soled riches on offer these days can be a daunting task.
Experts say the right footwear can make or break your workout, but money will not necessarily buy insole happiness, nor will following the foot traffic to the latest, trendiest model…
Robert Yang, a sports performance coach based in Encinitas, California, believes most people still wear shoes that force their toes together, and many wear shoes too big for them.
He said shoes should conform to the exact size of your foot…
Yang generally favors a flat, light shoe to highly constructed and cushioned ones with elevated heels.
He said separating the toes, a feature of some barefoot running shoes, increases the platform for stability…
Before you buy anything, he said, manipulate the shoe. Grab it at the heel and toe, bend it back and forth.
"It should bend near the ball of the foot because that's the natural hinge point," he said, adding the shoe should then be twisted…
No shoe should rub or pinch anywhere, he said.
Community: The shoes I’m wearing now are Nikes that I bought at the flea market for $5. They were used for testing, so you can see the spots where a machine held them in place, but they work just fine.

What's the best exercise for heart health?

(Reuters Health) A combination of weight training and aerobic exercise might be the best prescription for overweight people at risk for diabetes and heart disease, a new study suggests.
People doing only aerobic exercise dropped weight and inches off their waistlines -- so an aerobic-only program is also a good (and less time-consuming) option, researchers said. Those in the study who just lifted weights saw very little benefit in terms of heart health, although they did gain strength.
"Aerobic plus resistance is clearly the optimal program," said Dr. Timothy Church…
The findings, he told Reuters Health, are in line with other recent research and physical activity guidelines that suggest mixing in a little resistance training with regular aerobic exercise.

Yoga Boosts Stress-Busting Hormone, Reduces Pain, Study Finds

(Science Daily) A new study by York University researchers finds that practicing yoga reduces the physical and psychological symptoms of chronic pain in women with fibromyalgia.
The study is the first to look at the effects of yoga on cortisol levels in women with fibromyalgia. The condition, which predominantly affects women, is characterized by chronic pain and fatigue; common symptoms include muscle stiffness, sleep disturbances, gastrointestinal discomfort, anxiety and depression.
Previous research has found that women with fibromyalgia have lower-than-average cortisol levels, which contribute to pain, fatigue and stress sensitivity.
