2 Aug. 2012--tons of ready-to-eat foodstuffs and ready to cook have been recalled because of listeria in plant onions California.

Gillis onions Oxnard, Calif., processes more than 90 000 tonnes of red and yellow onions per year. A wide range of products, which the plant chopped, slivered and peeled onions.

How many products? After the July 25 announcement reminds flood gills develop earlier references to include all the onions made in the establishment. On 2 Aug. was at least 15 separate recalls involving major brands like Trader Joe 's, whole foods, Wegmans, and Publix.

Foods containing onions fresh chicken salad ranged from salsa to the bean dip. All references, including a description of all the products, sales dates and product codes are available on the FDA web site.

Although the gills onions were sold only in 12 u.s. States and in Canada, products containing onions were sent to additional countries. For example, the appeal yesterday's Garden-fresh salads, salsa, beans, slaw and onion dip products containing gills on the 14 States Stronger…. Nine of these countries were not included in the appeal, the gills.

The appeal began on July 18, the day after a random test bag of yellow onions in the gills in the retail sales showed listeria bacteria. Gills, immediately closed its plant on 17 July as the only recognized studies the FDA. After finding the object, the company voluntarily listeria expanded its withdrawal. The plant remains closed.

Not yet have been linked to diseases of withdrawn products. Many, but not all the withdrawn products have reached their sell-by date. Gill says that its products are of relevance of the 16-day.

Serious cases of Listeriosis-listeria infection---are relatively rare. People at high risk are the elderly and people with weakened immune system. Pregnant women usually do not get a serious illness of the same, but the infection can cause miscarriage, abortion, premature infant infections or critical.

People from listeria food poisoning usually decreased with the case of diarrhea, often with fever. Over days or weeks, may develop more severe symptoms: fever, stiff neck, confusion, weakness of muscles or vomiting.

Although the symptoms may appear as soon as possible after three days after eating contaminated food, the Symptoms usually appear within one to three weeks. However, some people become ill two months after eating contaminated food.

Options for increasing the coping with allergies Kids

By Serena Gordon
HealthDay Reporter

FRIDAY, Aug. 3, HealthDay News)--Children with a food allergy, a serious violation of the food, but usually have to methods currently in the process of development can change the common scenario.

More than 3 million young American,--approximately one of every 25--have an allergy of a particular type, usually for milk, eggs or peanuts, according to U.S. Government statistics. For them, "avoiding was the mainstay of treatment for a long time," said Dr. William Silvers, an allergist in private practice in Vail, Colorado, Idaho and spokesman, the American College of Allergy, asthma and Immunology.

"Now what we see is the increased interest in oral Immunotherapy," silvers said. "This means giving oral small and slowly increased doses of the food, which children are allergic to and building of the amount ingested food at time to desensitize the child so they sabotage."

That does not come from a string of slow, though. Dr. Carla Davis, allergist in the Texas children's Hospital in Houston, noted that after the children have been desensitized to certain foods, must continue to eat them regularly or they will again, allergic to food.

"No maintenance of tolerance If you avoid the food," she explained.

Together with the Desensitization of another potential new treatment for food allergies is omalizumab (Xolair) drug named. Silvers said that works by blocking the activity of substances that cause allergies known as immunoglobulin E (IgE) Allergic reactions, so will never be started.

However, the Allergy would come again if the person stop using the drug, which is currently only available in the form of inject and have not been previously approved by the U.S. Food and Drug Administration for use in children younger than 12.

Some scholars, however, believe that the combination of the two treatments may be better than either alone. The first test reports were very small, said that nine of the 11 children who were given Xolair and then desensitized to milk could exploit to 12 ounces of dairy per day without reaction.

Davis said that researchers are also testing herbal preparations and this one a combination of nine herbs was able to prevent serious allergic reactions known as Anaphylaxis, in mice. "Is another treatment, which may be their", she said, although as yet there is evidence in humans.

What was true, however, that many children simply expanded their food allergies, even some of the most deadly of these. Davis said that one in five of the discounts they can overcome the allergic to peanuts, but no longer meet the requirements that allergies to eggs, milk, soy and wheat are the most common enterprise. The tree generally peanuts, nuts and seafood allergies usually stay with the children, as they grow, said.

To know whether a child has a firm no longer complies with the requirements of the food allergies requires repeated skin and blood tests, silvers said. "If the IgE levels in the blood decrease in time, or if the skin comes back negative or very small response, child or adult may be given food challenge to see if you respond," he said.

To be certain, though the study "must be done under the supervision of a physician," Davis said, because of serious reaction can occur if the House Bunny is not no longer complies with the requirements of companies of allergies.

For children with food allergies lingering silver medals recommended that the child or parent will always have the antihistamine Benadryl and Epinephrine injection Pen. If it is suspected that the child inadvertently ingested food that causes allergies, House Bunny should be taken immediately antihistamine. If it worsens, administer epinephrine and allergic reactions for the emergency room as soon as possible.

It is important to go to the hospital after a serious allergic reactions, Davis said, because it may be the second wave reaction approximately four to six hours later.

Many children have their own pen, Epinephrine in the Office of their school nurse. In the Chicago public school system recently decided to take the next step and keep the supply of Epinephrine pens in each school and train school staff in their use, so that it is prepared to any serious allergic reactions.

"This is a good idea, because their first serious response is approximately one in five children in school," Davis said.

For those living with food allergies Davis said, it is important to find the balance between being vigilant and overanxious. Parents should be "prepared to respond, but you should not expect one all the time," she said. "Some parents are extremely anxious to contact their child may have with food. Health vigilance is important, but so is the quality of life. "

(HealthDay News) -- Extreme heat can make people sick, especially children. That's why parents should be prepared to get overheated kids out of the hot sun and into an air-conditioned building.

The American Academy of Pediatricians offers this advice:

If your home isn't air conditioned, visit a pubic building such as a library.Encourage your child to drink plenty of fluids all day long. Offer a drink before your child asks for one.Allow more naps and rest time than usual, as heat can make children feel tired.Have your child take a cool bath.Don't ever leave your child inside a hot car.

Modest weight loss can benefit long-term health

THURSDAY, Aug. 2 HealthDay News)--even modest weight loss can include the overweight and obese important health benefits worth a decade, according to new research.

Study included 3,000 people overweight impaired glucose tolerance--a condition of pre-diabetic--who demonstrated how to change their behavior instead of the recommended drugs.

Behavioral strategies used by participants to help them with everything turned on weight maintenance, reducing the amount they ate unhealthy food, kept in their home and increase their amount of physical activity.

Even modest weight loss--an average of 14 pounds--reduced the risk of type 2 diabetes by 58%. Weight loss and health benefits lasted for 10 years, even if the people regain the weight, "said study Author Rena Wing, a Professor of Psychiatry and human behavior at Brown University in Providence, R.I.

The test is scheduled for presentation Thursday at the American Psychological Association annual meeting in Orlando, Fla file.

"Help people find ways of changing their eating and activity behaviors and develop intervention other than medication to strengthen healthy lifestyles have made a huge difference in preventing one of the health problems in this country," Wing, who is also Director of the weight control and Diabetes Research Center at the Miriam Hospital in Providence, said in a news release.

"Weight loss of only 10 percent of body weight a person ... have also been shown the long-term impact on team sleep, sleep, hypertension and the quality of life and to release the decrease in mobility that occurs with age," she noted.

Wing is currently a study of 13 years 5000 people with type 2 diabetes to determine whether intensive behavioral intervention can reduce the risk of heart disease and heart.

"We want to show that behavior change not only creates healthier reduce risk factors for heart disease, but actually can make them live longer," she said.

Because the study was presented at the meeting of the medical data and conclusions should be seen as a preliminary to the time of publication in peer-reviewed Journal.

Some Improvement in Heart Risk Factors for Americans: CDC

AppId is over the quota
AppId is over the quota
By Steven Reinberg
HealthDay Reporter

FRIDAY, Aug. 3 (HealthDay News) -- About 47 percent of American adults have at least one risk factor for heart disease, according to a new report released Friday.

These risk factors include uncontrolled high blood pressure, uncontrolled high levels of "bad" LDL cholesterol and smoking, according to the U.S. Centers for Disease Control and Prevention.

"We have seen declines [in risk factors], but there's still work to be done," said the report's lead author, CDC health statistician Cheryl Fryar.

Findings of the report, culled from data gathered from the U.S. National Health and Nutrition Examination Survey, included:

A drop in the rate of adults with at least one risk factor from 58 percent in 1999 to 46.5 percent in 2010.Men (52 percent) are more likely than women (41 percent) to have one of these risk factors.From 1999 to 2010, there was a drop in the percentage of whites and Mexican Americans who had at least one risk factor (about 47 percent and 45 percent respectively).There was no decline in the percentage of blacks with these risk factors, which remained at 58 percent.The prevalence of uncontrolled high blood pressure and uncontrolled high LDL cholesterol dropped between 1999 and 2010 (almost 8 percent and 9 percent, respectively).There was no drop in the percentage of adult cigarette smokers, which remained at 25 percent of adults 20 and older.Disparities remain among people of different income levels and racial and ethnic groups.

"Cardiovascular disease and stroke are largely preventable, with uncontrolled high blood pressure, uncontrolled high LDL cholesterol levels and smoking representing major modifiable risk factors in men and women of all racial and ethnic groups and all income levels," said Dr. Gregg Fonarow, spokesman for the American Heart Association and professor of cardiovascular medicine at the University of California, Los Angeles.

"It is concerning that some of the early gains in lowering the rates of uncontrolled high LDL cholesterol appeared heading in the wrong direction in 2009 and 2010," Fonarow said. "This may represent recent misguided efforts to discredit the substantial cardiovascular benefits of LDL-lowering therapy."

The report found that there are significant disparities in risk factors by age, sex, race and income levels, Fonarow noted.

"African Americans and those with incomes of less than 130 percent of the poverty level had higher prevalence of risk factors and made less progress over the study period," he said. "The reasons behind these disparities in risk factor control are likely complex, but deserving of further study."

"Substantially increased efforts to reduce or eliminate these uncontrolled cardiovascular disease and stroke risk factors at the individual, community, national and global level are clearly needed," Fonarow added.

Reasons for the stalled decline in smoking rates are not clear. Possible explanations include less money spent by states on antismoking campaigns and more advertising dollars spent by tobacco companies.

The CDC recently launched a campaign of graphic ads to get smokers to quit. Early results indicate the campaign is working.

"We have to have sustained efforts like this if we are going to have an impact on decreasing the number of smokers in this country," Dr. Len Lichtenfeld, deputy chief medical officer at the American Cancer Society, said at the time of the campaign's launch. "One of the sad facts is that although we had success a number of years ago in getting people to stop smoking, we have hit a roadblock where 20 percent of Americans still smoke."

One of the major problems is that tobacco companies easily outspend the government's efforts to curb smoking with vast sums devoted to promoting their products, Lichtenfeld said.

West Nile virus on rise in us: CDC

THURSDAY, Aug. 2 HealthDay News)--so far this year, State of 241 cases of West Nile virus, and four related deaths the UNITED STATES experiencing the largest collection in mosquito diseases since 2004, health officials report.

Eighty percent of these infections occurring in three Member States--Texas, Mississippi and Oklahoma--which have seen business earlier than usual. Overall, 42 States has detected a virus, West Nile virus to humans, birds or mosquitoes from 31 July, the Centre for disease prevention and control said Wednesday.

"It's not clear why we see more activity than in recent years," Dr. Marc Fischer, Arboviral Diseases Branch of the Agency's medical Schwartz, said in a news release, CDC. "Irrespective of the reason for the increase, people should be aware of the West Nile virus activity in their area and take action to protect themselves and their families."

Typically, the greatest risk of the infection with West Nile virus occurs from June to September, with cases peaking in mid-August. However, changes in the weather, the number of infected mosquitoes and human behavior can have all the effects when and where outbreaks of the virus, the CDC noted.

The best way to protect against West Nile virus is to avoid getting bitten by mosquitoes. CDC officials recommended the following protective measures:

Use insect Repellents when outside. Wear long sleeves and pants at dawn and dusk.Install or repair screens on Windows and doors.Use of air conditioning, where possible. Do not leave standing water outside in open containers, such as buckets, flowerpots, and kiddie pools.

People infected with West Nile virus can develop a fever, headache, body aches, joint pains, vomiting, diarrhea, or a rash. In more extreme cases, the virus can lead to serious illness, such as neurologic core encephalitis (inflammation of the brain or surrounding tissues) or death. People older than 50 and with medical conditions such as cancer, diabetes, hypertension, kidney disease and organ transplants are at higher risk for serious disease.

Although most people with mild cases of the West Nile virus will recover on their own, the CDC recommends that anyone who develops symptoms of the disease should see their doctor immediately.

When the Act of the parents, so do Kids: study

THURSDAY, Aug. 2 HealthDay News)--parents who want to increase the amount of exercise for their children should become more active themselves, according to a new study.

"Long known that parent and child activity levels are correlated," study Author Kristen Holm, Assistant Professor of medicine at National Jewish Health in Denver, said in a news release. "[This study] showed that when parents increase their activities, the children also increased. The effect was more pronounced in the weekend. "

Study, published in the July issue of journal of physical activity and health, involved the 83 families participating in the programme designed to weight gain among overweight and obese children aged from 7 to 14.

Parents and children in the program are encouraged to increase their level of daily activity by walking 2,000 more steps every day. Their progress was tracked with pedometers.

Research has shown that mothers have reached or exceeded the objective on the days of the 2,000-step, their children give an average of 2,117 more. When mothers has not achieved the objective, their children were only 1,175 perform additional steps. The researchers pointed out that the children who were less active when the program started more additional steps than children who were more active.

Overall, the researchers found that for each 1000 additional steps taken by the mother, their child endeavoured 196 more. The researchers Saw a similar structure between fathers and their children.

The researchers suggested that parents and children together perform frequently at weekends resulted in the increase in exercise.

Pregnant mothers can support the development of fetal Gut changes

THURSDAY, Aug. 2 HealthDay News)--obtain a change in the composition of intestinal microbes that normally would cause health problems such as weight and inflammation may actually be beneficial for the pregnant, according to the researchers.

In conducting the research, published in the Aug. 3 edition of the journal cell, scientists tested stool samples taken from 91 women in pregnancy. It appeared that the composition of intestinal microbes women changing in time, from the first quarter of their pregnancy at the third trimester.

"This is the first in-depth characterization of intestinal microbiota associated with pregnancy," study senior author, Ruth Ley, Cornell University, said in a news release. log "The findings suggest that our body have coevolved with the microbiota and can actually use them as a tool to help you change the metabolism of the mother--to promote the development of the fetus."

In the course of their pregnancy, intestinal microbes women became less "normal" and less varied. Researchers also found that the number of bacteria beneficial bacteria levels associated with rejected as the disease has increased. There was also evidence that inflammation increased during the pregnancies of women.

"Changes in intestinal microbes do not relate to diet, so we think that the immune system or the hormones play a role," Ley noted.

The researchers then passed the transfer of pregnant women healthy mouse intestinal bacteria. They found mice that received transfer of the bacteria from the third trimester got fatter and had higher levels of inflammation markers in blood sugar metabolism, and worse than the mice that received the first trimester of the micro-organism.

"By the third trimester, the microbiota may entail changes in metabolism," Lei said. "In the context of pregnancy, these changes in the mother are healthy metabolic because they promote the energy storage in fat tissue support and assistance of the fetus. Beyond the pregnancy, however, these changes may lead to the development of type 2 diabetes and other health problems. "

Why women Outlive men: Fruit Flies provide clues

THURSDAY, Aug. 2 HealthDay News)--New research shows that mutations to the DNA of mitochondria to cause men to age faster than women--a statement that may explain why women, on average, outlive men.

Researchers from Monash University in Australia examined male and female fruit flies, which transported mitochondria--the part of the cell that converts food into energy--the origin of the variety. It appeared that genetic variants in mitochondria predicted life expectancy in males, but not in the case of females. Researchers found that several of the mutations in the mitochondria DNA affects how quickly men aged and their durability.

"Intriguingly, these same mutations do not affect the patterns of aging in females. They affect only males, "Dr. Damian Dowling, of the school of biological sciences, Monash University, said in a news release. "All animals have the mitochondria, and tendency to outlive males to females is common to many different species. Our results therefore suggest that mutations mitochondrialnego, which we have no cover will generally faster aging of the male sex in the Animal Kingdom. "

Mutations result from the way in which mitochondrial genes are passed down from one generation to the next, noted the authors of the study.

"When the children receive copies of most of their genes both their mothers and fathers, only receive the mitochondrial gene from their mothers. This means that the quality control process in evolution, known as natural selection, only the screen quality of mitochondrial genes in the dams, "explained Dowling. "If the mitochondrial mutation occurs injures fathers, but does not affect mothers, the mutation will be using through the gaze of natural selection, without return. Over thousands of generations, many such mutations have accumulated that harm only to males, females, leaving unscathed. "

The authors of the study said that they intend to continue their research and study ways to reverse the genetic mutation, which negatively affect women's life.

Research has been published in current biology, Aug. 2.

Spray-on Skin May Promote Wound Healing

Experts Predict Role for Spray-on Skin in Slow-Healing Wounds

By Denise Mann
WebMD Health News

Reviewed by Louise Chang, MD

Aug. 2, 2012 -- An experimental spray-on skin product may help people with chronic leg wounds heal faster and more effectively than available treatments, a new study suggests.

The spray-on skin is made up of skin cells and suspended in a mixture of different types of proteins. The participants in this study all had venous leg ulcers, which are shallow wounds that occur in people who have a circulation problem in their veins. These wounds tend to develop on the inside of the lower leg. Most at risk for venous ulcers are inactive and obese people, as well as people with varicose veins.

People in the study who used the new treatment experienced a greater reduction in wound size than those who didn't use it.

The findings appear in the Lancet.

Healthpoint Biotherapeutics of Fort Worth, Texas, is developing the new product and sponsored the study.

As it stands, most venous leg ulcers are treated with compression bandages. Some doctors also use skin grafts in which skin is taken from another area of the body and used to resurface the wound. Skin grafts involve surgery, and people can develop a wound at the skin donation site, too.

"If you don't get these to heal, they become chronic, and the older the wounds are, the harder they become to heal with anything," says researcher Herbert B. Slade, MD. He is a pediatrician at the University of North Texas Health Science Center in Fort Worth and is also the chief medical officer at Healthpoint Biotherapeutics. "Compression bandages work for 30% to 70% of people, but are not 100% effective."

That is where the spray-on treatment may come in.

In the 12-week study of 205 people, those who received the spray-on treatment and compression bandaging had a greater reduction in wound size than those who used compression bandaging without the test treatment.

Researchers tested two strengths of the new therapy, along with compression bandages. The biggest improvements were seen in the lower-strength dose given every two weeks; there was a 16% greater reduction on average of the wound area, compared to a group that was given a spray that didn't contain the new therapy, after 12 weeks.

Side effects were similar in the different groups. The spray-on treatment sped wound closure by an average of 21 days compared to the comparison group.

Slade and colleagues are now assessing its safety and conducting studies to determine exactly how it works. "The FDA wants us to better define what it is that is happening when the cells get on the surface of the wound," he says. "We know it works, we just need to know more about how."

According to Slade, the sprayed-on cells help the tissue learn how to regenerate itself. If the findings are confirmed by follow-up studies, "it's going to be an off-the-shelf product." No information is available about cost at this time.

The need for new products to treat these wounds is tremendous, Matthias Augustin, MD, says in an email. "A significant number of patients fail to respond to any therapy."

Augustin, the director of the Institute for Health Services Research in Dermatology and Nursing at the University Clinics of Hamburg in Hamburg, Germany, wrote an editorial accompanying the new study.

"New treatments with improved healing and healing rates are needed to reduce the burden of ulcers for patients, [and] while more research is needed I believe that this product could ultimately make a significant difference for these patients."

John Lantis, MD, is one of the investigators on the study. "This could be used in any place that artificial skin is needed, such as diabetic foot ulcers," says Lantis, who is the chief of the vascular surgery division at St. Luke's-Roosevelt Hospital in New York City.

It will not be a stand-alone treatment. "If you have a diabetic foot ulcer, you will still have to wear special diabetic shoes," he says. "It's not like you can just spray it on and go about your business. It will always be used in conjunction with current standard of care."

It seems to perform better than any other artificial skin products out there or in the pipeline, Lantis says.

Maja Zaric, MD, says there may well be a role for this product. She is an interventional cardiologist at Lenox Hill Hospital in New York City. "The spray can be applied in various doses and it is very user-friendly, unlike a skin graft."

Still, not every person with a venous leg ulcer would benefit from the new spray-on skin. "Those who would benefit the most have extremely large ulcers and decreased blood flow," she says. Before treating these wounds, Zaric always does a vein-mapping study to see which veins are causing the problem.

Neil Sadick, MD, is a New York City dermatologist and clinical professor of dermatology at Weill Cornell Medical College. "This treatment provides a cocktail of cells and growth factors," he says. "These ingredients can stimulate new collagen, which would improve wound healing and also help recover the skin." Collagen is the main structural protein in skin.

"It could well be helpful in wound healing and it could be helpful in any area where we need to replace the skin surface," Sadick says.

"In the context of pregnancy, these changes in the mother are healthy metabolic because they promote the energy storage in fat tissue support and assistance of the fetus. Beyond the pregnancy, however, these changes may lead to the development of type 2 diabetes and other health problems. "

Why women Outlive men: Fruit Flies provide clues

THURSDAY, Aug. 2 HealthDay News)--New research shows that mutations to the DNA of mitochondria to cause men to age faster than women--a statement that may explain why women, on average, outlive men.

Researchers from Monash University in Australia examined male and female fruit flies, which transported mitochondria--the part of the cell that converts food into energy--the origin of the variety. It appeared that genetic variants in mitochondria predicted life expectancy in males, but not in the case of females. Researchers found that several of the mutations in the mitochondria DNA affects how quickly men aged and their durability.

"Intriguingly, these same mutations do not affect the patterns of aging in females. They affect only males, "Dr. Damian Dowling, of the school of biological sciences, Monash University, said in a news release. "All animals have the mitochondria, and tendency to outlive males to females is common to many different species. Our results therefore suggest that mutations mitochondrialnego, which we have no cover will generally faster aging of the male sex in the Animal Kingdom. "

Mutations result from the way in which mitochondrial genes are passed down from one generation to the next, noted the authors of the study.

"When the children receive copies of most of their genes both their mothers and fathers, only receive the mitochondrial gene from their mothers. This means that the quality control process in evolution, known as natural selection, only the screen quality of mitochondrial genes in the dams, "explained Dowling. "If the mitochondrial mutation occurs injures fathers, but does not affect mothers, the mutation will be using through the gaze of natural selection, without return. Over thousands of generations, many such mutations have accumulated that harm only to males, females, leaving unscathed. "

The authors of the study said that they intend to continue their research and study ways to reverse the genetic mutation, which negatively affect women's life.

Research has been published in current biology, Aug. 2.

Most Americans with Celiac disease do not understand: the test

THURSDAY, Aug. 2 HealthDay News)--new research suggests that the 1.4 million Americans have celiac disease, but do not know, while 1.6 million people are on a gluten-free diet for celiac disease--treatment--even though they may not be necessary.

The results, which estimates that 1.8 million Americans have celiac disease--autoimmune condition--indicate that the percentage of 78 patients do not always realize that they have the condition.

"This is proof that the disease is common in the United States," said co-author Dr. Joseph Murray, a gastroenterologist at the Mayo Clinic in the news release. "If you have one person to detect every five or six [who] are not very good job we're doing, celiac disease detection."

People with celiac disease have trouble sample of wheat, rye and barley. Gluten-free diet can help, but around 80% of the people on such a diet not recognized in celiac disease.

"There are many people on a gluten-free Diet and not clear what is the medical need for that," said Murray. "This important if someone thinks that they have celiac disease, that they be tested first before they go on a diet."

The researchers came to their conclusions by examining the results of tests of blood and establish a national test.

Celiac disease seems to be particularly common in the white race.

"Virtually all of the people we were non-Hispanic Caucasians," said co-author Dr. Alberto Rubio-Tapia, Mayo Clinic gastroenterologist, release news. But, he said, the results are head scratching because studies in Mexico had suggested that the disease celiac is common.

Research was partially funded by the U.S. National Institutes of Health and the Centre for disease prevention and control.

Study appears in the American Journal of Gastroenterology, July 31.

The progress of Alzheimer's slower after 80: study

By Steven Reinberg
HealthDay Reporter

THURSDAY, Aug. 2 HealthDay News)--the Deadly March Alzheimer is less in people age 80 or older than younger elderly, scientists have found.

The risk of developing Alzheimer's increases with age, and by 85, the risk is about 50 percent. But those who develop progressive brain disorder that at the end of life will be less aggressive than the disease whose symptoms appear in the 1960s and 1970s, according to researchers at the University of California, San Diego.

Lead researcher Dominic Holland from the University Department of neurosciences, said that doctors will need to consider these findings, assessing the elderly patients with Alzheimer 's.

"Methods of early detection, which will be based on biomarkers, as well as mental capacity, you should consider the age of the persons assessed," he said. Because the "old" elderly could deteriorate in a slightly slower rate than younger patients, doctors may not realize that these people suffering from Alzheimer 's.

The findings also have relevance for the assessment of potential Alzheimer's treatment and prognosis for patients of different Alzheimer's care costs, clinical Holland and other experts say.

There is currently no effective treatment or the treatment of Alzheimer 's, which gradually destroys the cells of the brain and robs people of memory and their ability to perform everyday tasks and communication.

The report was published online in the journal PLoS Aug. 2 one.

Study progress of Alzheimer, Holland and colleagues used data from the research initiative of the Alzheimer's disease Neuroimaging. They looked at more than 700 people aged 65 to 90, some with normal mental functioning, some mild symptoms of dementia and other persons suffering from Alzheimer 's.

Participants are tested every 6 or 12 months.

The researchers found that Alzheimer's patients lost mental skills to younger more quickly than older patients.

The decline among patients younger paralleled the accelerated loss of brain tissue and increase bone marrow or knob fluid Alzheimer's seen among the younger age group, compared with older patients, study authors added.

Researchers are not sure why Alzheimer's is more aggressive in younger patients. One explanation may be that older patients are decreasing trend in this slower pace for a longer period of time, in some unknown factor keeping symptoms at bay, they suggest.

Another possibility is the older patients with dementia Alzheimer 's, which can place plus the full effect of Alzheimer's in the brain. But such a diagnosis must be made with the Visual inspection, which is the only way that Alzheimer's is diagnosed, Holland noted carefully.

Alzheimer's disease currently affects an estimated 5.6 million Americans, and this number is expected to triple by 2050 as the baby boom generation ages.

Finding that previous develops the disease more aggressive is not good news for those younger older patients who suffer losses for a long time, the deterioration of their mental capacities, Holland said.

Another expert said that the findings may have implications for predicting costs of health and clinical trials.

"This is an extremely important paper about the impact on both the forecast costs of care for Alzheimer's and planning clinical trials," said Dr. Sam Gandy, Associate Director of the Mount Sinai Alzheimer's Disease Research Center at the Mount Sinai School of Medicine in New York City.

If the clinical picture in the over-85 population is milder than what is typical in populations Younger, these older patients would remain independent already and projections for the economic burden to the health care system should be adjusted, he said.

"Annual cost of 200 billion dollars in the United States now is; the projection of $ 1 trillion annually by 2050, "Gandy says.

"Maybe that $ 1 trillion is really only $ 500 to 750 billion dollars. Still catastrophic, but it is worth taking this into account, "he added in the projection.

Equally important, if the speed of the decline is less than 85 years of age at the age of 65-years, which must be taken into account during the recruitment for clinical trials, Gandy said.

For example, if all of the patients receiving the drug were more than 85 and all patients receiving inactive placebo were significantly younger, it might appear that the drug worked, when in fact the population were incorrectly matched, Gandy pointed out.

"We must know that we wanted the population to be identical as possible, but really do not know the specific of this phenomenon before," he said.

Modest weight loss can benefit long-term health

THURSDAY, Aug. 2 HealthDay News)--even modest weight loss can include the overweight and obese important health benefits worth a decade, according to new research.

Study included 3,000 people overweight impaired glucose tolerance--a condition of pre-diabetic--who demonstrated how to change their behavior instead of the recommended drugs.

Behavioral strategies used by participants to help them with everything turned on weight maintenance, reducing the amount they ate unhealthy food, kept in their home and increase their amount of physical activity.

Even modest weight loss--an average of 14 pounds--reduced the risk of type 2 diabetes by 58%. Weight loss and health benefits lasted for 10 years, even if the people regain the weight, "said study Author Rena Wing, a Professor of Psychiatry and human behavior at Brown University in Providence, R.I.

The test is scheduled for presentation Thursday at the American Psychological Association annual meeting in Orlando, Fla file.

"Help people find ways of changing their eating and activity behaviors and develop intervention other than medication to strengthen healthy lifestyles have made a huge difference in preventing one of the health problems in this country," Wing, who is also Director of the weight control and Diabetes Research Center at the Miriam Hospital in Providence, said in a news release.

"Weight loss of only 10 percent of body weight a person ... have also been shown the long-term impact on team sleep, sleep, hypertension and the quality of life and to release the decrease in mobility that occurs with age," she noted.

Wing is currently a study of 13 years 5000 people with type 2 diabetes to determine whether intensive behavioral intervention can reduce the risk of heart disease and heart.

"We want to show that behavior change not only creates healthier reduce risk factors for heart disease, but actually can make them live longer," she said.

Because the study was presented at the meeting of the medical data and conclusions should be seen as a preliminary to the time of publication in peer-reviewed Journal.

West Nile virus on rise in us: CDC

THURSDAY, Aug. 2 HealthDay News)--so far this year, State of 241 cases of West Nile virus, and four related deaths the UNITED STATES experiencing the largest collection in mosquito diseases since 2004, health officials report.

Eighty percent of these infections occurring in three Member States--Texas, Mississippi and Oklahoma--which have seen business earlier than usual. Overall, 42 States has detected a virus, West Nile virus to humans, birds or mosquitoes from 31 July, the Centre for disease prevention and control said Wednesday.

"It's not clear why we see more activity than in recent years," Dr. Marc Fischer, Arboviral Diseases Branch of the Agency's medical Schwartz, said in a news release, CDC. "Irrespective of the reason for the increase, people should be aware of the West Nile virus activity in their area and take action to protect themselves and their families."

Typically, the greatest risk of the infection with West Nile virus occurs from June to September, with cases peaking in mid-August. However, changes in the weather, the number of infected mosquitoes and human behavior can have all the effects when and where outbreaks of the virus, the CDC noted.

The best way to protect against West Nile virus is to avoid getting bitten by mosquitoes. CDC officials recommended the following protective measures:

Use insect Repellents when outside. Wear long sleeves and pants at dawn and dusk.Install or repair screens on Windows and doors.Use of air conditioning, where possible. Do not leave standing water outside in open containers, such as buckets, flowerpots, and kiddie pools.

People infected with West Nile virus can develop a fever, headache, body aches, joint pains, vomiting, diarrhea, or a rash. In more extreme cases, the virus can lead to serious illness, such as neurologic core encephalitis (inflammation of the brain or surrounding tissues) or death. People older than 50 and with medical conditions such as cancer, diabetes, hypertension, kidney disease and organ transplants are at higher risk for serious disease.

Although most people with mild cases of the West Nile virus will recover on their own, the CDC recommends that anyone who develops symptoms of the disease should see their doctor immediately.

THURSDAY, Aug. 2 HealthDay News)--parents who want to increase the amount of exercise for their children should become more active themselves, according to a new study.

"Long known that parent and child activity levels are correlated," study Author Kristen Holm, Assistant Professor of medicine at National Jewish Health in Denver, said in a news release. "[This study] showed that when parents increase their activities, the children also increased. The effect was more pronounced in the weekend. "

Study, published in the July issue of journal of physical activity and health, involved the 83 families participating in the programme designed to weight gain among overweight and obese children aged from 7 to 14.

Parents and children in the program are encouraged to increase their level of daily activity by walking 2,000 more steps every day. Their progress was tracked with pedometers.

Research has shown that mothers have reached or exceeded the objective on the days of the 2,000-step, their children give an average of 2,117 more. When mothers has not achieved the objective, their children were only 1,175 perform additional steps. The researchers pointed out that the children who were less active when the program started more additional steps than children who were more active.

Overall, the researchers found that for each 1000 additional steps taken by the mother, their child endeavoured 196 more. The researchers Saw a similar structure between fathers and their children.

The researchers suggested that parents and children together perform frequently at weekends resulted in the increase in exercise.
