Eat Less, Live Longer?

(HealthDay News) People who cut their daily caloric intake by 25 percent or more may live longer than those who do not, a new study suggests.
Researchers from the Washington University School of Medicine in St. Louis found that significantly limiting calories lowers core body temperature (the temperature at which all of the functions in the body can operate with maximum efficiency), which has been shown to prolong life.

Does sleep loss up weight by lowering energy use?

(Reuters Health) Sleep deprivation makes the day drag and appears to put a drag on metabolism, causing the body to use less energy, European researchers found in a small study.
The results … add to evidence that a lack of shut-eye can promote weight gain -- not just by boosting hunger, but by slowing the rate at which calories get burned.

The Importance of Core-Strengthening

(SouthBeachDiet.com) Dr. Arthur Agatston emphasizes the importance of functional fitness — core-strengthening exercises that mimic everyday activities, such as bending, lifting, and pressing — in addition to cardio conditioning. Here’s more on the benefits of functional fitness:
It will strengthen your core muscles.
Functional exercises require you to use several muscle groups in one fluid movement. This will strengthen and develop the muscles in the back, abdomen, pelvis, and hips, and promote stability and flexibility — all essential for preventing injury and helping you maintain a healthy weight.
It will tone your muscles and improve bone density.
Even if you're diligent about cardio workouts, you need core strengthening exercises to further improve muscle tone and bone density. Combining a cardio routine with core training will not only make you stronger but will also help promote good posture and balance.
No expensive equipment needed!
The best part? The functional exercises featured in the South Beach Supercharged Fitness Program don't require you to buy fancy, expensive equipment like balance boards and pulley-type machines to see results. We recommend the following:
·         A bench or a chair without arms
·         A mat or thick towel to protect your back and knees during floor exercises
·         Light hand weights
·         An exercise step, also called an aerobic step or a home-exercise workout step

3 Supplements for Strong Bones

(Andrew Weil, M.D.) As men and women age, they can experience a loss of bone mass as well as normal wear and tear on the joints. Small preventive measures can help to protect joints and keep bones strong - consider the following supplements:
1.    Calcium. People who don't get enough calcium may lose bone mass faster and fracture bones more easily. Taking half as much magnesium with supplemental calcium will help offset any constipating effects. I recommend women supplement with 500 to 700 mg of calcium citrate in two divided doses taken with meals for a total of 1,000-1,200 mg from all sources (including diet); most men do not need calcium supplements, but should instead get 500-600 mg per day through diet.
2.    Vitamin D. It facilitates the absorption of calcium, helping to support healthy and strong bones. It also promotes bone mineralization. Get regular sun exposure (about 20-30 minutes a day is adequate), and take 2,000 IU of vitamin D per day - look for supplements that provide D3 (cholecalciferol) rather than D2 (ergocalciferol).
3.    Vitamin K. It helps activate certain proteins that are involved in the structuring of bone mass. Low intake of vitamin K has been linked to low bone density. You can get adequate amounts of vitamin K through a diet rich in leafy greens, such as Swiss chard, kale, parsley, spinach, broccoli, cauliflower and Brussels sprouts.

Nibble This Dark Treat for a Healthy, Happy Stomach

(RealAge.com) If you've got a soft spot for chocolate, give yourself a little pat on the tummy. Turns out the antioxidants in chocolate may be good for your gut.
In a new study, drinking antioxidant-rich cocoa daily increased the levels of protective gut bacteria in people's stomachs…
[R]esearchers found that the high-flavanol cocoa had kicked up people's levels of Lactobacillus and Bifidobacterium -- two beneficial types of gut bacteria that help slow the growth of disease-causing bacteria and organisms. Bifidobacteria may also help with vitamin synthesis and have cholesterol-improving powers. (Related: Find out how dark chocolate can help make you smarter, too.)

'Fasting Pathway' Points the Way to New Class of Diabetes Drugs

(Science Daily) A uniquely collaborative study by researchers at the Salk Institute for Biological Studies uncovered a novel mechanism that turns up glucose production in the liver when blood sugar levels drop, pointing towards a new class of drugs for the treatment of metabolic disease…
"These exciting results show that drugs that inhibit the activity of class II HDACs may be worthwhile to be pursued as potential diabetes drugs," says [Reuben J. Shaw, Ph.D.]. Recently, many drug companies have been developing HDAC inhibitors as anti-cancer drugs, so Shaw speculates that some of these compounds, which may or may not be useful for cancer, could have therapeutic potential for the treatment of insulin resistance and diabetes.

New Findings on Noninvasive Test for Pancreatic Cancer

(Science Daily) Pancreatic cancer has one of the highest mortality rates of any of the major cancers, and of the 43,000-plus Americans diagnosed with the disease each year, more than 94 percent die within five years of diagnosis. One reason for this high number of deaths is a lack of effective screening tools for catching the disease early. Now, in an effort to try to gain the upper hand on this deadly form of cancer, Mayo Clinic researchers believe they have found a new way to test for pancreatic cancer with DNA testing of patients' stool samples…
The study focused on detecting methylations in stool samples of 127 patients, 60 diagnosed with pancreatic cancer and 67 who were not diagnosed with cancer. Methylation is a type of DNA modification strongly associated with cancers and pre-cancers…
The screening detected the markers regardless of the stage of cancer or the location of the cancer within the pancreas.

Blood Test for Lung Cancer?

(Science Daily) Researchers have identified characteristic patterns of molecules called microRNA (miRNA) in the blood of people with lung cancer that might reveal both the presence and aggressiveness of the disease, and perhaps who is at risk of developing it. These patterns may be detectable up to two years before the tumor is found by computed tomography (CT) scans.
The findings could lead to a blood test for lung cancer.

Toward a Vaccine for Methamphetamine Abuse

(Science Daily) Scientists are reporting development of three promising formulations that could be used in a vaccine to treat methamphetamine addiction -- one of the most serious drug abuse problems in the U.S…
Meth is highly addictive, and users in conventional behavioral treatment programs often relapse. Previously tested meth vaccines either are not effective or are very expensive. To overcome these challenges, the researchers made and tested new vaccine formulations that could potentially be effective for long periods, which would drive down costs and help prevent relapse.
The group found that three of the new formulations that produced a good immune response in mice (stand-ins for humans in the lab) were particularly promising.

Telemonitoring Success May Depend on Patients' Age, Literacy Level

(HealthDay News) Heart failure patients who are older than 65 and have a high level of health literacy are more likely to continue using telemonitoring technology that tracks their condition than younger people with low health literacy, a new study finds.
Health literacy refers to the ability to read, understand and use health care information. Telemonitoring systems, which help doctors monitor patients outside of office visits, are seen as a way to improve care for heart failure patients, but results so far have been mixed.
The new study shows that individual characteristics play a major role in patients' interest and success in using telemonitoring systems -- knowledge that could help improve the design of such systems and increase patient participation, the researchers said.

Climate change bringing infection, hunger, illness

(Reuters Health) Climate change threatens far more than our environment. It's already led to the spread of infectious diseases and respiratory ailments across the globe and contributed to thousands of deaths through heat waves and other extreme weather events. It's even fueled recent revolts in the Middle East and North Africa.
That's according to Dan Ferber and Dr. Paul Epstein, the authors of a new book, Changing Planet, Changing Health: How the Climate Crisis Threatens Our Health and What We Can Do about It
The health of all humans is directly tied to how we, as communities, nations, and a global population, respond to the growing climate threat, says Ferber, a science journalist and Epstein, Associate Director of the Center for Health and the Global Environment at Harvard Medical School.

Ostracism, exclusion cause physical pain

(UPI) Being excluded doesn't leave physical bruises but it can cause deeper pain that lasts longer than a physical injury, U.S. researchers say.
Kipling D. Williams, a professor of psychological sciences at Purdue University, says when a person is ostracized, the brain's dorsal anterior cingulate cortex, which registers physical pain, also feels social injury…
"Being excluded is painful because it threatens fundamental human needs, such as belonging and self-esteem," Williams says. "Again and again research has found that strong, harmful reactions are possible even when ostracized by a stranger or for a short amount of time."

Canadian Psychiatrists Acknowledge the Benefits of Placebos, Survey Shows

(Science Daily) A recent survey … reports that one in five respondents -- physicians and psychiatrists in Canadian medical schools -- have administered or prescribed a placebo.
Moreover, an even higher proportion of psychiatrists (more than 35 per cent) reported prescribing subtherapeutic doses of medication (that is, doses that are below, sometimes considerably below, the minimal recommended therapeutic level) to treat their patients.
Prescribing pseudoplacebos -- that is treatments that are active in principle, but that are unlikely to be effective for the condition being treated, e.g., using vitamins to treat chronic insomnia -- is more widespread than we may have thought according to the survey…
The survey, which was also designed to explore attitudes toward placebo use, found that the majority of responding psychiatrists (more than 60 per cent) believe that placebos can have therapeutic effects. This is a significantly higher proportion than for other medical practitioners.
Community: As we’ve discussed before, the placebo effect is very powerful, and the more we know about it the more we’ll be able to use it.

4 Steps to a Positive Outlook

(Andrew Weil, M.D.) Being pessimistic can be more than just an emotional drain on yourself and those around you - pessimism has been linked to a higher risk of dying before age 65. The good news is that expressing positive emotions such as optimism is associated with a variety of health benefits: lowered production of the stress hormone cortisol, better immune function and reduced risk of chronic diseases. If you are stressed-out or anxious, which can be either a cause or an effect of a pessimistic outlook, try the following:
1.    Take care of yourself by eating a healthy diet, exercising regularly and getting adequate sleep.
2.    Express your emotional reactions honestly so you can effectively deal with what's bothering you.
3.    Confide in someone - your mate, a good friend or a trusted relative.
4.    View the cup as half full instead of half empty.
You can also benefit from positivity in the form of laughing, celebrating friends and family, learning to forgive and more!

Ultrasound as Effective as CT Scans for Most Diagnoses, Research Finds

(Science Daily) For diagnosing head and neck ailments, tests that use radiation are always less desirable than those that don't. Otolaryngologists have a wide range of techniques available to them, including CT or "CAT" scans, MRI and ultrasound. CT uses significant radiation and MRI a lower amount, but ultrasound is a non-invasive, non-radiating technique. It does not require injection of radioactive contrast material and has no side effects.
Now, a new study … exploring the efficacy of expensive and invasive CT scans has found that, in some cases, they don't offer a clinical advantage over a simple, inexpensive ultrasound procedure.

Celebrex may curb colon cancer, but with caveats

(Reuters Health) People who took a newer type of pain pill over a three-year period were less likely to develop polyps that could lead to colorectal cancer -- but at the expense of a higher risk of heart problems, new study findings report.
And when participants stopped taking the pain pill Celebrex (celecoxib) out of concerns over side effects, they eventually developed more polyps than people who had remained on an inactive, or placebo, drug throughout the study…
The study … received financial support from Pfizer, which sells Celebrex.
This is not the first study to suggest Celebrex and similar drugs -- known as COX-2 inhibitors - may reduce the risk of developing colon cancer, [Dr. Andrew Chan] said, but people need to balance that potential benefit with the higher risk of cardiovascular complications.

Mitochondria: Body’s Power Stations Can Affect Aging

(Science Daily) Mitochondria are the body's energy producers, the power stations inside our cells. Researchers at the University of Gothenburg, Sweden, have now identified a group of mitochondrial proteins, the absence of which allows other protein groups to stabilise the genome. This [stabilization] could delay the onset of age-related diseases and increase lifespan…
"When a certain MTC protein is lacking in the cell, e.g. because of a mutation in the corresponding gene, the other MTC proteins appear to adopt a new function. They then gain increased significance for the stabilisation of the genome and for combating protein damage, which leads to increased lifespan," says Thomas Nyström.

Lung scans may lead to overdiagnosis: study

(Reuters Health) U.S. researchers say they have found clear signs that blood clots in the lungs are being overdiagnosed, exposing patients to potentially dangerous side effects from unnecessary drugs.
Using national data, the researchers found the rate of so-called pulmonary embolisms, or PEs, nearly doubled with the introduction of a new powerful diagnostic test more than a decade ago.
Yet there was only a slight drop in deaths from the condition over the same period, suggesting many of the clots were too small to cause harm.
"Rather than an epidemic of disease, we think the increased incidence of PE reflects an epidemic of diagnostic testing that has created overdiagnosis," the researchers write.
