Approximately half of all American adults with suffer some kind of mental illness during their lifetime, a CDC reports announced. The authors stress the need for better surveillance in order to improve treatment and prevention.

Ileana Arias, Ph.D., principle deputy director of CDC, said:

"We know that mental illness is an important public health problem in itself and is also associated with chronic medical diseases such as cardiovascular disease, diabetes, obesity, and cancer. The report's findings indicate that we need to expand surveillance activities that monitor levels of mental illness in the United States in order to strengthen our prevention efforts."



According to a SAMHSA (Substance Abuse and Mental Health Services Administration) study carried out in 2009, 4.8% of America's adult population - 11 million people - had suffered a mental illness during the preceding twelve months. They define a mental illness as "a diagnosable mental disorder (that) has substantially interfered with, or limited one or more major life activities."

This study reports that over the previous twelve months, about 8.4 million American adults thought seriously about suicide, 2.2 made plans to end their lives, and about one million attempted to commit suicide.

SAMHSA administrator Pamela S. Hyde, said:

"This new CDC study combined with SAMHSA's latest surveillance data provides a powerful picture of the impact of mental illness on public health. People with mental disorders should seek help with the same urgency as any other health condition.

Treatment and support services are effective and people do recover."

(Reuters) Europeans are plagued by mental and neurological illnesses, with almost 165 million people or 38 percent of the population suffering each year from a brain disorder such as depression, anxiety, insomnia or dementia, according to a large new study.

With only about a third of cases receiving the therapy or medication needed, mental illnesses cause a huge economic and social burden -- measured in the hundreds of billions of euros -- as sufferers become too unwell to work and personal relationships break down.

"Mental disorders have become Europe's largest health challenge of the 21st century," the study's authors said.

At the same time, some big drug companies are backing away from investment in research on how the brain works and affects behavior, putting the onus on governments and health charities to stump up funding for neuroscience.

"The immense treatment gap ... for mental disorders has to be closed," said Hans Ulrich Wittchen, director of the institute of clinical psychology and psychotherapy at Germany's Dresden University and the lead investigator on the European study.

"Those few receiving treatment do so with considerable delays of an average of several years and rarely with the appropriate, state-of-the-art therapies."

Wittchen led a three-year study covering 30 European countries -- the 27 European Union member states plus Switzerland, Iceland and Norway -- and a population of 514 million people.

A direct comparison of the prevalence of mental illnesses in other parts of the world was not available because different studies adopt varying parameters.

Wittchen's team looked at about 100 illnesses covering all major brain disorders from anxiety and depression to addiction to schizophrenia, as well as major neurological disorders including epilepsy, Parkinson's and multiple sclerosis.

The results, published by the European College of Neuropsychopharmacology (ENCP) on Monday, show an "exceedingly high burden" of mental health disorders and brain illnesses, he told reporters at a briefing in London.

Mental illnesses are a major cause of death, disability, and economic burden worldwide and the World Health Organization predicts that by 2020, depression will be the second leading contributor to the global burden of disease across all ages.

Wittchen said that in Europe, that grim future had arrived early, with diseases of the brain already the single largest contributor to the EU's burden of ill health.

The four most disabling conditions -- measured in terms of disability-adjusted life years or DALYs, a standard measure used to compare the impact of various diseases -- are depression, dementias such as Alzheimer's disease and vascular dementia, alcohol dependence and stroke.

The last major European study of brain disorders, which was published in 2005 and covered a smaller population of about 301 million people, found 27 percent of the EU adult population was suffering from mental illnesses...

Man Dies From Toothache, Couldn't Afford Meds

"He [Willis] might as well have been living in 1927..."

Man Dies From Toothache, Couldn't Afford Meds

A 24-year-old Cincinnati father died from a tooth infection this week because he couldn't afford his medication, offering a sobering reminder of the importance of oral health and the number of people without access to dental or health care.

According to NBC affiliate WLWT, Kyle Willis' wisdom tooth started hurting two weeks ago. When dentists told him it needed to be pulled, he decided to forgo the procedure, because he was unemployed and had no health insurance.

When his face started swelling and his head began to ache, Willis went to the emergency room, where he received prescriptions for antibiotics and pain medications. Willis couldn't afford both, so he chose the pain medications.

The tooth infection spread, causing his brain to swell. He died Tuesday.

Calls to Willis' family were not immediately returned. University Hospital in Cincinnati, where Willis was admitted, did not comment, citing federal privacy laws.

"People don't realize that dental disease can cause serious illness," said Dr. Irvin Silverstein, a dentist at the University of California at San Diego. "The problems are not just cosmetic. Many people die from dental disease."

Willis' story is not unique. In 2007, 12-year-old Deamonte Driver also died when a tooth infection spread to his brain. The Maryland boy underwent two operations and six weeks of hospital care, totaling $250,000. Doctors said a routine $80 tooth extraction could have saved his life. His family was uninsured and had recently lost its Medicaid benefits, keeping Deamonte from having dental surgery.

"When people are unemployed or don't have insurance, where do they go? What do they do?" Silverstein said. "People end up dying, and these are the most treatable, preventable diseases in the world."

Getting access to dental care is particularly tough for low-income adults and children, and it's getting tougher as the economy worsens. In April, the Kaiser Family Foundation reported that 33 percent of people surveyed skipped dental care or dental checkups because they couldn't afford them. A 2003 report by the U.S. Surgeon General found that 108 million Americans had no dental insurance, nearly 2.5 times the number who had no health insurance.

Trips to the dentist aren't the only expenses hard-up Americans are skipping. An August report by the Commonwealth Fund found that 72 percent of people who lost their health insurance when they lost their jobs said they skipped needed health care or did not fill prescriptions because of cost.

"People want to believe there's a safety net that catches all of these people, and there isn't," said Dr. Glenn Stream, president-elect of the American Academy of Family Physicians. He noted that it is often young men who are the most likely to lack health coverage.

Dr. Jim Jirjis, director of general internal medicine at Vanderbilt University, said people, like Willis, without access to care often die of conditions that were much more common decades ago.

"He [Willis] might as well have been living in 1927,"
Jirjis said. "All of the advances we've made in medicine today and are proud of, for people who don't have coverage, you might as well never have developed those."...

Myth busted: Potatoes help fight BP sans weight gain

Myth busted: Potatoes help fight BP sans weight gain
Times of India
Sep 2, 2011

LONDON: Potatoes are generally discarded by most people as fatty food. But, a new study now claims that eating spuds daily can help lower your blood pressure; and moreover, there is also no weight gain involved. In the study, researchers fed 18 volunteers six to eight spuds twice a day.

Most of those taking part were overweight or obese and on pills to lower blood pressure. And, the spuds used were purple ones cooked unpeeled in a microwave. But researchers believe that redskin potatoes and white potatoes may have similar effects.

After a month, the upper of their blood pressure reading when blood is pumped with each beat of the heart, was down by 3.5%. Diastolic or the lower readings decreased by 4.3%. In addition, none of the volunteers put on any weight, the Daily Mail reported.

"Mention 'potato' and people think 'fattening, high carbs, empty calories'. We hope our research helps to remake potato's popular nutritional image," lead researcher Dr Joe Vinson of the University of Scranton in Pennsylvania was quoted as saying.

>Special Report: A pinch of doubt over salt

Special Report: A pinch of doubt over salt
By Kate Kelland, Health and Science Correspondent
Sep 1, 2011

(Reuters) - In Britain it started with Sid, the "giant slug with a message", who slicked his way onto television screens back in 2004 as part of a government health campaign to warn people about the dangers of consuming too much salt. "Stay away from fast cars, loose women and SALT!" he screamed.

Sid's message -- that liberal sprinklings of sodium, the main component of salt, don't only kill slugs but humans too -- has now become conventional wisdom worldwide. High salt intake is linked to high blood pressure, or hypertension, a key risk factor for strokes, heart attacks and other cardiovascular diseases. Together those rank as the world's number one killers. The World Health Organization (WHO) puts cutting salt intake alongside quitting smoking as one of the top 10 "best buys" in public health...

But the findings that policy-makers have accepted as settled are not as clear-cut among scientists. A study in July by the much-respected Cochrane Library, which conducts meta-analyses of scientific data by grouping together the best studies on a subject and pooling the results, found no evidence that reducing salt intake cuts the risk of developing heart disease or dying before your time.

In that study Rod Taylor, a professor of health services research at Exeter University, analyzed seven randomized controlled trials covering more than 6,500 people and found that although cutting down did appear to lead to slight reductions in blood pressure, this did not translate into lower risk of heart disease or premature death.

In one group of people -- those with pre-existing heart conditions -- reducing salt was actually associated with an increase in the likelihood of premature death.


Taylor said he did not receive payment from, or have links to, the salt industry. His study was funded by a grant from the UK government's National Institute for Health Research.

Taylor's study came hot on the heels of another, by Belgian scientists, which was published in the Journal of the American Medical Association (JAMA). That found people who ate lots of salt were no more likely to get high blood pressure, and were statistically less likely to die of heart disease, than those with low salt intake.

The researchers used data from two different studies, involving a total of around 3,700 Europeans whose salt consumption was measured through urine samples. The scientists divided the participants into three groups with low, medium and high intake: those with the lowest salt intake had the highest rate of death from heart disease - at 4 percent. People who ate the most salt had the lowest death rate from heart disease, at less than 1 percent.

"One should be very careful in advocating generalized reduction in sodium intake in the population at large. There might be some benefits, but there might also be some adverse effects," says Jan Staessen, head of hypertension studies at the University of Leuven and the lead investigator on the Belgian study. "You have to ask, should public health policies be based on something which is still being debated? I don't think so."

Staessen told Reuters he had no financial conflicts of interest. His work was funded largely by grants from the European Union and European national governments.

WHO SAYS A TEASPOONFUL WILL DO?

Such studies are re-drawing the battle lines around salt. Foodmakers are starting to fight back against the low-salters. Campbell's is now putting more salt back into all 31 of its Select Harvest soups after consumers voted with their taste buds and stopped buying the reduced-salt version.

"One size doesn't fit all," says Juli Mandel Sloves, Campbell's senior manager for nutrition and wellness communications. "And what this research debate shows is exactly that. You can't make a recommendation based on the needs of only one part of the population. It's really important that we offer a variety of choices."

Other major food industry groups and manufacturers approached by Reuters, including Kellogg's and Pepsico, as well as the U.S. Grocery Manufacturers' Association, either declined to be interviewed or sent statements reiterating their commitment to reducing sodium levels in their foods, in line with government dietary recommendations.

But the powerful U.S. National Restaurant Association is questioning the accepted wisdom. "The science is very clear in showing that reducing sodium reduces blood pressure. There's no question about that. The controversy is around reducing cardiovascular disease and ... basically the risk of death. That's where the evidence is completely weak," says Joy Dubost, the NRA's Director of Nutrition and Healthy Living. In other words, cutting back on salt does reduce blood pressure, but it may not reduce the risk of dying early.

Michael Alderman, a blood pressure expert at Albert Einstein College of Medicine in the United States and editor of the American Journal of Hypertension, believes there's a sense that some scientists -- and most policymakers -- may have moved too early to target salt as the cause of the problem. "If we're doing something so dramatic to the diets of whole populations, there should be no argument. The evidence should be overwhelming, but it's not overwhelming at all," he said.

Of around a dozen scientists interviewed by Reuters for this story, about half shared this point of view; but since they included salt-reduction campaigners and salt industry representatives, that is not necessarily an indicator of the balance of opinions across the scientific community.

Alderman argues that in addition to changing blood pressure, cutting sodium can cause other physiological changes such as increased resistance to insulin -- which can set the stage for diabetes and increase the risk of death from heart disease. Too little sodium can also increase sympathetic nerve activity which raises the risk of heart attacks, and boost the secretion of aldosterone, a hormone produced by the adrenal gland that is bad for the cardiovascular system.

"What we have -- like almost all interventions in health and medicine -- is something that produces a multitude of different effects," said Alderman, who disclosed having taken one $750 payment more than a decade ago from the Salt Institute, but who said he has since had no financial help from the industry. Besides Alderman and Heagerty, none of the other academic scientists interviewed for this article have disclosed financial interests.

In a letter to the British government seen by Reuters, the UK's Salt Association -- which along with the Salt Institute has a vested interest in defending the salt industry -- cites the Cochrane and JAMA papers and demands an urgent review of the salt reduction strategy. It goes as far as to say: "People may actually be dying as a result of poorly founded advice."

IS SALT THE NEW TOBACCO?

That kind of talk exasperates the Wolfson Institute's MacGregor, one of the most vocal advocates of salt reduction anywhere. Along with Franco Cappuccio, head of the WHO's collaborating center for nutrition at Warwick University and Simon Capewell, a professor of clinical epidemiology at Liverpool University, McGregor argues that salt -- most of it hidden in processed and packaged foods -- is a huge problem.

It's perhaps an indication of his conviction that MacGregor equates the argument about salt to past rows over tobacco, even though unlike tobacco, salt is a fundamental nutritional requirement for humans to survive.

"We're in exactly the same position as we were with tobacco 20 or 30 years ago when people were still arguing about whether tobacco caused lung cancer or heart disease," MacGregor says. "It obviously did, there was no doubt about it -- and the only people arguing were people who had commercial interest."

WASH and its UK counterpart CASH (Consensus Action on Salt and Health), which is also chaired by MacGregor, are funded by donations from individuals and charities.

Cappuccio and Capewell point to scores of scientific analyses to make their point. A 2007 study predicted that reducing salt intake around the world by 15 percent could prevent almost 9 million deaths by 2015. Another study published in March 2010 found that cutting salt intake by 10 percent in the United States could prevent hundreds of thousands of heart attacks and strokes over decades and save the government $32 billion in healthcare costs.

In a recent British Medical Journal commentary, Capewell and Cappuccio cautioned: "Denial and procrastination will be costly in terms of both avoidable illness and expenses."

When confronted with the two most recent scientific studies suggesting the contrary, MacGregor dismissed them as flawed or paradoxical. "There is absolutely no evidence of any harm from reducing salt intake. Absolutely none," he said.

In the case of the Cochrane review, MacGregor set about re-crunching the numbers and swiftly published a fresh analysis of the data in a rival medical journal, The Lancet, which drew the opposite conclusion.

Taylor responded by saying MacGregor had taken two of the sets of data in the study -- one from people with normal blood pressure and one from people with hypertension - and grouped them together. This, he said, is like comparing apples and oranges, and breaks a central tenet of statistical analysis.

Manchester University's Tony Heagerty has a wry observation of this to-and-fro: "If you torture data long enough it will give you the answer you want."

ONE BIG EXPERIMENT

Much of the argument barely touches on the data -- descending instead into personal attacks and accusations of conflicts of interest. Scientists on both sides talk of being taunted by their rivals. Both Cappuccio, who advocates less salt, and Staessen, the hypertension expert who has found risks in salt reduction, say they have been victimized or intimidated after publishing papers in scientific journals.

Salt-reduction advocate MacGregor points at one of his main opponents across the Atlantic, Morton Satin, director of science and research at the U.S.-based Salt Institute, who says reducing salt across whole populations may do more harm than good. "Imagine he's wrong," MacGregor said. "That would mean he's responsible for millions of strokes worldwide. When he goes to sleep tonight, he might like to think about that."

Satin hits back that the whole situation has left science behind. "Passions overtake an objective view of science... and we can have an entire society being led to believe something that doesn't stack up."

There is one thing the two sides appear to agree on: the matter could be settled by a large-scale -- 20,000 to 30,000 people -- randomized clinical trial with half allocated to a high and half to a low salt diet. To be done properly, the main protagonists agree, such a trial would need to run for several years. The huge numbers are needed so that all other possible factors -- weight, age, fitness, quality of diet, and medical conditions -- are roughly equal in both groups.

But salt-reduction advocates MacGregor and Cappuccio say such a trial would be prohibitively expensive, unnecessary, and may even be unethical. Again they draw comparisons with smoking. Since, in their view, the harms of salt are indisputable, asking people to be kept on a high salt diet for the purposes of a medical experiment would be equivalent to forcing people to smoke.

Alderman is enraged by such suggestions. "Any medical ethicist would say that before you impose changes you have to make sure they are safe and beneficial. If the science is uncertain, then how can it be unethical to do the right studies to answer the scientific questions? If you're asking 300 million Americans and I don't know how many millions of other people around the world to change their diet so dramatically, you ought to have overwhelming evidence that it's a good idea and it's safe."

Until the row is settled, people's salt intake will probably be guided by personal taste.
