(HealthDay News) -- When it comes to picking up emotional signals from others, the brain responds to happiness faster than sadness, a new study has found…

"Positive expressions, or expressions of approach, are perceived more quickly and more precisely than negative or withdrawal ones," study author J. Antonio Aznar-Casanova told a Spanish science news service. "So, happiness and surprise are processed faster than sadness and fear."…

Determining how people make value judgments based on first impressions is important in many areas of society, said Aznar-Casanova, adding that "these inferences can strongly influence election results or the sentences given in trials."

(Everyday Health) "I'll let you in on a big secret," says Dr. [Arthur] Agatston. "Physicians who practice aggressive prevention have seen heart attacks and strokes practically disappear from their practice. It's that simple — this approach can literally prevent heart attacks and strokes and save lives. My goal in writingThe South Beach Heart Program was to speed the pace of the cardiac prevention revolution currently taking place in this country." To that end, Dr. Agatston has performed pioneering work in noninvasive cardiac imaging that has resulted in computerized tomography (CT) scanning methods and measures that bear his name: the Agatston Score and the Agatston Method, which are used to screen for atherosclerosis — and are recognized worldwide. The Agatston Score derived from the CT scan is the single best predictor of your risk for a future heart attack.

According to Dr. Agatston, studies like this continue to lend support to a noninvasive, aggressive prevention approach. "All of the latest research and evidence suggests that we already have the tools and knowledge to prevent the majority of heart attacks and strokes. Now we just need to put these methods into practice — and start saving more lives."

(Science Daily) Individuals with higher mid-life Body Mass Index (BMI) in the 1960s have been found to have lower memory and thinking skills and a sharper decline in these abilities in old age, compared to those with lower BMI in mid-life…

“We have extended this knowledge and shown that being overweight or obese in mid-life also negatively affects memory and thinking skills independent of dementia. Moreover, these skills decline more rapidly in old age among those who were overweight or obese in mid-life,” writes Anna Dahl in an article published in the Journal of Gerontology.

(CNN) When snoring starts to affect your daily habits, you should see a doctor, said Dr. Thomas LoRusso, director of the Northern Virginia Sleep Diagnostic Centers.

"A bed partner may notice that the patient stops breathing and snores loudly, " LoRusso said. "And the daytime symptoms are sleepiness, poor concentration, problems waking up in the morning."

LoRusso says a good way to check your sleep habits is to note your levels of fatigue during the day and jot down other symptoms you might be having. And if you have a bed partner, ask whether he or she has noticed any "choking or gasping while you snore," he said. "The person you sleep with, many times, knows your snoring better than you."

Specific lifestyle changes can help you avoid sleep apnea, the sleep foundation said.

LoRusso agrees. "Cut out the alcohol," he said. "It can make the upper airway muscles to relax."

And watch your weight. Losing pounds can "cure" sleep apnea, especially for overweight people, LoRusso said. If you smoke, try to quit, he said. Smoking creates swelling in the upper airway, making apnea worse.

These seemingly small changes can have dramatic results.

(Reuters) - A Seattle clinic for people fed up with insurance, started by doctors fed up with insurance, has gotten $4 million in private venture capital money to expand, it announced on Monday.

Qliance says it has a profit-making solution to the problems of long waits, rushed doctors and cursory care that bother patients, at the same time that it eliminates the paperwork and pressure that plague primary care doctors…

Co-founder Norm Wu said per-patient revenue is triple that of insurance-based clinics. He said many costs are fixed so the firm, now losing money, will turn to profit as business grows.

More than 50 noninsurance clinics operate in 18 U.S. states, based on different business models, Wu noted.

(Well, New York Times) Last year, researchers from Queen’s University in Belfast decided to investigate anecdotal reports from dog owners who said their pets warned them of hypoglycemic attacks. They surveyed 212 dog owners, all of whom had Type 1 diabetes, an autoimmune disorder that prevents the body from producing insulin. A regular concern with Type 1 is that blood sugar will drop precipitously low, causing a person to fall unconscious.

Among the dog owners, 138, or 65 percent, said their dog had shown a behavioral reaction to at least one of their hypoglycemic episodes. About a third of the animals had reacted to 11 or more events, with 31.9 percent of animals reacting to 11 or more events. The dogs got their owners’ attention by barking and whining, (61.5 percent), licking (49.2 percent), nuzzling (40.6 percent), jumping on top of them (30.4 percent), and/or staring intently at their faces (41.3 percent). A small percentage of the dogs reportedly tremble in fear at the time of a hypoglycemic attack.

(New York Times) Every year consumers spend billions of dollars on supplements, diet foods, books and meal replacements. But the truth is that success depends not so much on what diet plan you choose or what program you join…

A study published in the Feb. 26 issue of The New England Journal of Medicine, for instance, compared four popular diets and found they all produced similar results. After two years, the dieters in each group lost an average of nine pounds. Notably, the dieters who attended more counseling sessions lost a little bit more, which may support the notion that behavior is more important than diet alone.

Motivation, though, is not always easy to come by — especially when it involves changing habits. Some people may need a little help to kick-start a weight-loss regimen, whether that means following a popular diet or enrolling in an organized program. Your goal, though, should not be short term.

“Keeping weight off permanently is a lifelong process,” says James O. Hill, a psychologist and a founder of the National Weight Control Registry (www.nwcr.ws), a database of 6,000 people who have lost weight and kept it off.

All of the men received behavioral interventions, which included advice on reducing caffeine and alcohol, limiting nighttime fluids and paying attention to room temperature, noise, and lighting. Drug therapy -- for BPH, frequent urination, and sleep issues -- was also started where appropriate.

After 4 weeks, the men reported a significant decrease in nighttime trips to the bathroom. The men in general also reported feeling significantly less bothered by the condition.

The men also reported significant improvements in the time it took them to get to sleep, fall back to sleep and their overall quality of sleep.

(Science Daily) A new report … shows that populations across the globe are suffering from the impact of low levels of vitamin D. The problem is widespread and on the increase, with potentially severe repercussions for overall health and fracture rates…

The main risk factors for low vitamin D levels include older age, female sex, lower latitudes, winter season, darker skin pigmentation, less sunlight exposure, dietary habits, and the absence of vitamin D fortification in common foods. Further factors include the increase in urbanization, where people tend to live and work indoors, as well as cultural practices that tend towards sun avoidance and the wearing of traditional clothing that covers the skin. The severity of the problem in Middle East and South Asia arises from the combination of several of these risk factors.

These findings suggest that prevention strategies must be initiated at the national level - especially given the increasing ageing of populations in many regions of the world. National plans of action should encourage safe, limited exposure to sunlight and improved dietary intake of vitamin D, whilst considering fortification of foods as well.

(Science Daily) Experimental devices that read brain signals have helped paralyzed people use computers and may let amputees control bionic limbs. But existing devices use tiny electrodes that poke into the brain. Now, a University of Utah study shows that brain signals controlling arm movements can be detected accurately using new microelectrodes that sit on the brain but don't penetrate it.

"The unique thing about this technology is that it provides lots of information out of the brain without having to put the electrodes into the brain," says Bradley Greger, an assistant professor of bioengineering and coauthor of the study. "That lets neurosurgeons put this device under the skull but over brain areas where it would be risky to place penetrating electrodes: areas that control speech, memory and other cognitive functions."

(HealthDay News) -- The more alcohol men drink, the more time they spend in a hospital, research from the United Kingdom has found…

A unit of alcohol, or an average drink, was considered to be half a pint of beer (about a cup) or a 4-ounce glass of wine, for example, according to the study.

The researchers tracked the men's health for an average of 28 years, focusing on the occurrence of heart and respiratory diseases, stroke and alcohol-related illnesses and conditions.

Men who drank more than 22 units of alcohol a week had a 20 percent higher hospital admission rate than non-drinkers, the study found.

Even relatively low levels of alcohol consumption were associated with a higher number of days spent in the hospital, the researchers found. Drinkers of eight or more units of alcohol a week were hospitalized more days than non-drinkers, and the length of stay increased as weekly consumption of alcohol went up.

The heaviest drinkers spent 58 percent longer in a hospital than non-drinkers, according to the study.

(Arthur Agatston, MD, Everyday Health) If you are an American age 40 to 70, the odds are about 40 percent that you've been diagnosed with prediabetes, diabetes, or metabolic syndrome. Shocked by this statistic? You should be! Not long ago, diabetes and prediabetes were rare. Now they are virtual epidemics in the United States, putting tens of millions of Americans at high risk for heart disease. In fact, diabetes is such a strong risk factor for heart disease that medical professionals define it as a "coronary heart disease risk equivalent." This means that a person with diabetes has the same high risk of a heart attack as someone who has already had one. Up to 70 percent of people in coronary care units have prediabetes or diabetes…

[N]ational guidelines recommend that people with diabetes keep their blood pressure below 130/80. Giving up cigarettes is even more important for people with diabetes than it is for others, because smoking and diabetes are a deadly combination. Type 2 diabetes is also closely linked with obesity (see Chapter 5), which explains why, as the American population gets fatter, the rate of type 2 diabetes is soaring. What is even more alarming is that there are millions more "diabetics in training" in our country today. I am speaking of our children, who, as they grow fatter and less fit, are rapidly becoming prediabetic or even diabetic. Type 2 diabetes can no longer be called an "adult-onset" disease.

Luckily, type 2 diabetes is largely a "man-made" disease that we can unmake if we set our minds to it. Exercise, weight loss, and strategic dietary changes — particularly eliminating the highly processed "bad carbs" found in baked goods, breads, snack foods, and other starchy and sugary favorites — are all very effective in reversing insulin resistance.

Orthopedic surgeons are seeing a "tidal wave" of 45- to 64-year-olds suffering from exercise-related injuries they've dubbed "boomeritis," Dr. Ray Monto, a spokesman for the American Academy of Orthopedic Surgeons (AAOS), told Reuters Health…

These injuries are largely due to people not giving themselves enough time to rest up after tough workouts, according to Monto… "You can't beat yourself up the way you did when you were 20 because it takes longer to recover," he said.

Middle-aged people today are a lot more active than their parents were, he added, which is a good thing. "We're basically fitter and more athletic now longer into our lives than we ever were."

But, he added, older athletes need to take a few precautions to protect themselves from injuries like rotator cuff tears, tendonitis and stress fractures.
