HEALTH MANAGEMENT. Reference to the cause of childhood discovered hydrocephalus

Scientists at The Scripps Research Institute have found what may be a major cause of congenital hydrocephalus, one of the most common neurological disorders of childhood that produces mental debilitation and sometimes death in premature and newborn children.
The research appears in the journal Science Translational Medicine.
Hydrocephalus, which involves excess buildup of cerebrospinal fluid in the brain, affects about 1 in 500 children in the United States. Currently only symptomatic treatment exists - the surgical placement of a shunt to drain away excess fluid. Researchers want to know the condition's causes, so they can figure out how to prevent and treat it. Scientists have known for some time that hydrocephalus was linked to bleeding events in the developing brain, but the reason for that linkage has not been clear.
The new study now suggests that hydrocephalus can be triggered by abnormal levels of lysophosphatidic acid (LPA), a blood-borne lipid that can enter the brain in high concentrations during bleeding events, with profound effects on developing brain cells. The study showed that both blood and LPA itself acted through the same receptor (receptors are proteins to which one or more specific kinds of signaling molecules bind) to produce defects in the brains of developing mice that led to severe hydrocephalus; genetic removal of a specific LPA receptor or pre-treatment with a compound that blocked the receptor largely prevented the condition.
"This provides proof of concept for the medical treatment of this disease," said Jerold Chun, MD, PhD, a professor at Scripps Research and its Dorris Neuroscience Center, and senior author of the new study, "and it also hints that this mechanism involving LPA could be relevant to other neurological conditions associated with altered brain development."
A Eureka Moment
Chun's laboratory specializes in the study of lipid-signaling molecules involved in the developing brain, including LPA. LPA is normally produced in the fast-growing fetal brain, and appears to be important for the normal development of neural "progenitor" cells. But when the researchers added abnormally high concentrations of LPA to the brains of fetal mice, they found an unexpected effect on brain development. "When we looked at their condition as newborns, we were surprised to see that they uniformly had big, fluid-filled brains," said postdoctoral fellow Yun Yung, PhD. "It was a Eureka moment, because we realized that LPA might help explain hydrocephalus."
Reviewing the medical literature on the condition, Chun and Yung noted that it was often linked to brain-bleeding events in the womb and typically also featured some improperly developed brain structures. "Our experiments with LPA connected both sets of findings," said Yung, "because LPA is involved in blood clotting and can reach very high concentrations during hemorrhages; plus, our LPA-exposed mouse brains had structural abnormalities like those reported in human cases."
Cerebrospinal fluid cushions the brain, provides it with basic nutrients, and is normally produced by the membrane-like choroid plexus within the fluid-filled chambers of the brain known as ventricles. Ependymal cells that line these ventricles have hair-like extensions that are thought to promote the normal flow of fluid. "In our LPA-exposed mice, there were patches in the ventricular lining where these ependymal cells were missing, which could have led to a disruption of the normal cerebrospinal fluid flow," said Yung. Structures in the ventricles that normally permit the proper drainage of fluid also appeared to be partly blocked by the improper overgrowth of cells, which might have further contributed to the brain-damaging fluid buildup.
The researchers were able to repeat these effects using the normal LPA-containing fluid fractions of blood, thus showing that bleeding events plausibly can lead to hydrocephalus by increasing the brain's exposure to LPA.
To investigate how LPA exerted this effect, the team produced mice that genetically lack one or both of the two receptors - LPA1 and LPA2 - to which LPA can bind on ventricle-building fetal progenitor cells, finding that the LPA1 receptor was required to produce hydrocephalus. "The idea here is that excess LPA causes these ventricular progenitor cells to get the wrong developmental signals via their LPA receptors, and so the ventricles and brain develop abnormally," said Chun.
In a final demonstration, the team pre-treated normal fetal mice with a compound that blocks the activation of LPA1 receptors, and found that even after LPA exposure, their signs of hydrocephalus were greatly reduced.
Looking Ahead
LPA1-blocking drugs currently are being developed for other conditions including lung fibrosis, and the new finding from Chun's lab may lead biotech or pharmaceutical companies to study their use in hydrocephalus. "If you had an unborn baby who was at risk from an injury to the mother, an infection, or evidence of bleeding then, in principle, you could treat with a short-acting LPA1 blocker to prevent or reduce hydrocephalus," said Chun.
The discovery that excess LPA can wreak havoc in the developing brain could have broader implications as well. Abnormally high concentrations of LPA may be generated by fetal brain cells themselves, also producing abnormal LPA signaling. Moreover, schizophrenia, autism, and other developmental brain disorders have also been linked to fetal bleeding events and infections as well as ventricular abnormalities.
"It's something that we need to investigate further," said Chun, "but it may be that excess LPA exposure in an unborn child's brain can have a variety of adverse effects on development, depending on the part of the brain that's exposed, the stage of brain development, and the duration of the exposure."
This work was supported by the National Institutes of Health, the National Science Foundation, and the Hydrocephalus Association.

HEALTH MANAGEMENT. Food-related outbreaks - FDA says new pilot projects help in the detection of products will be responsible

Yesterday, the U.S. food and Drug Administration explained that the ability for agencies and industry's to detect products responsible for foodborne illness outbreaks will be improved by two new pilot projects.
Under to existing FDA contract, the pilot projects will be conducted by the Institute of food technologists (IFT), a nonprofit scientific society consisting of experts engaged in food science, food technology, and related professions, at the direction of the FDA.
Signed into law in January, the food safety Modernization Act calls for the FDA to establish a minimum of two pilot projects: one which involves produce and the other involving processed foods. The FDA is also directed by the act to create record keeping requirements for high-risk foods in order to help trace products.
Michael R. Taylor, FDA deputy commissioner, for foods explained:

"We can prevent illnesses and reduce the economic impact to the food industry if we can more quickly determine what foods may be causing an outbreak and what foods can be eliminated from consideration."
"We recognize the importance of engaging stakeholders throughout the process and wants to consider what is practical for facilities of varying sizes and capabilities."

Assess methods and technologies for almost wants the trials and effective tracing of foods, such as types of data that are useful for tracing, ways to link the various points in the supply chain, and how fast the data are made available to the FDA.
Important of stakeholder groups, including industry, government, and consumers, will have a say in the trials, and efforts will be made supply chain, from farms to restaurants and grocery stores to incorporate those representing the food.
Following the completion of the pilots and when additional data is collected, the FDA will initiate rule making requirements for foods that are high risk to make easier tracing. The FDA must outline high-risk foods, taking into account such factors as the known risks of a food based on foodborne illness data, the likelihood that a particular food has a high potential risk for contamination, and the likely severity of an illness attributed to a particular food. Three public meetings during the comment period on the proposed rule will be held by the FDA.

HEALTH MANAGEMENT. Delete old cholesterol way could be used to Unfur of arteries

Called "Self digestion", the cumulative dysfunctional molecules from cells, clears cholesterol an old phone way Autophagy also mobilized and exports and provide for a totally new goal under the direction of the University of Ottawa Heart for drugs "unfur arteries" or reverse atherosclerosis, the main cause of heart attack and stroke, according to the Research Institute (UOHI) in Canada.
Run Director of HDL biology laboratory, UOHI and colleagues from UOHI and Columbia University in New York, United States, found, remained, during the evolution researcher Dr. Yves Marcel, Autophagy, a process that developed and is in single-cell organisms, devours and digested cholesterol which in artery walls has accumulated.
In a statement published yesterday Marcel said 8 September, the press:
"The finding that Autophagy regulated offers also functions to digest and free cholesterol from cells, and the fact that we know that this option will hope for the development of new drugs, enable the export of cholesterol could arteries."
Cholesterol is an important and necessary molecule in mammals, where it produced, hormones and cell membranes and is carried out by the body in the blood. However, it collects in the arteries, that they "fur up" and turn in the atherosclerosis, where narrower and narrower, finally caused blockages and circulation of the heart, which frequently causes heart attacks and strokes reduces arteries,.
Rockefeller Mireille Ouimet, an essential factor in the work, said:
"It is urgently necessary to understand how the accumulation can be reversed by cholesterol in the arteries."
Researchers have discovered that cholesterol accumulation itself raises cholesterol Autophagy, caused, published and broken by the liver, where it is removed from the body be and.
Marcel suggests that perhaps some people with coronary heart disease (CHD) unable to cholesterol in your arteries Autophagy option to delete. A route for new drugs could reactivate this option.

HEALTH MANAGEMENT. Hospital workers only other health care

By Debra Sherman
CHICAGO | Mon Sep 12, 2011 12: 25 am EDT
CHICAGO (Reuters) - hospital employees spend 10% more health consume more medical services and are generally sicker than the rest of the workforce U.S., according to a study released on Monday.
The cost difference was even greater, if members with health costs were taken into account 13 percent with care and prescription drugs.
The study, conducted by Thomson Reuters healthcare, analyzed the risk to the health and the use of 1.1 million hospital workers and compared them with 17.8 million health plan members from all sectors across the country.
Researchers consider not the reasons for the differences.
In the health sector were more frequently diagnosed and hospitalized in the hospital employees and their families, to treat asthma, diabetes, heart failure, HIV, hypertension and mental illness.
Found that the average cost of health care for hospital employees and their relatives $4.662 per year--$ 538 higher than in the general population.
MORE VISITS, THE HE
Hospital staff and their families saw their doctors less often, but were more likely to visit 22 percent to an emergency room and spent 18 percent more time in the hospital, which resulted in study.
Kreg Sherbine, co-author of the study speculated that easy access to expensive play a role can supply.
"If they right are in the hallway of the emergency room, it could be even easier to go than to arrange an appointment with a doctor," said Sherbine.
He said the stressful environment of a hospital and the irregular hours, which can be many hospital staff work together make it difficult to maintain, one other factor a healthy lifestyle.
Sherbine said that he doubted that the reason was the exposure to disease in the workplace, because there were differences in the numerous diseases such as diabetes and obesity.
"Consciousness could be a factor." We know that chronic diseases often unrecognized. You can reasonably determine that professionals are better about their symptoms and therefore more likely to seek treatment. However does not explain that the excessive difference in usage, "he said."
Researchers found that a hospital or health system an estimated $1.5 million per year for each 1 per cent reduction of the health would save costs with 16,000 employees in medicine and pharmacy.
"There are sectors with higher risks associated." The manufacturing sector, for example, is generally older and has even less healthy people, "said Sherbine."
But with the increasing financial pressure on hospitals, hospital administrators must pay attention to their bottom line, he said.
"Salaries and benefits are their biggest cost." We think that it is really important for hospitals, this address, ", he said."

HEALTH MANAGEMENT. Child-parent relationship has a video game

Kids who think that their parents arms monitors or Gaul, which many tend, video games more than other children, according to a study by researchers of the Michigan State University.
The study by the National Science Foundation is one of the first funded parental behavior with children-video game play links. The researchers surveyed more than 500 students from 20 schools and found that the more children with their parents behavior as negative (such as "NAGs a lot"), and the less control parents have, the more children video games.
Lead researcher Linda Jackson, who next step is to find out what said children video game behavior - a subject of Jackson and her team plan is fueling to check.
"The parents the child into the world of video games, perhaps to go is negative interactions with their child parental negativity to escape?", said Jackson, Professor of psychology. "Or, Alternatively, causing the video game play feel the child and his relationship with the parent as negative?"
Also, it could play another feature of the child, which is responsible for the relationship between perceptions of parent negativity and video games, she said.
Jackson said an equally interesting question of the relationship between video game play and actual rather than perceived behaviour of the parents. Perceptions not always mirroring reality, said they, and this may be the case in the over-and-child relationship.
The study is in the proceedings of the 2011 World Conference on educational multimedia, hypermedia & telecommunications.
The study is part of a larger project in which Jackson and colleagues school performance, social life, psychological well-being and moral reasoning study the impact of technology on children.

HEALTH MANAGEMENT. Lose a baby increases risk of early death for parents, mothers in particular

Losing a child during his/her first 12 months of life can considerably raise the parents' risk of dying early, researchers from the University of York, England and Stirling University, Scotland reported in BMJ Supportive & Palliative Care.
Dr Mairi Harper and team examined 5% of UK death registrations of parents who had lost a child aged 1 year or more, as well as parents who had lost a child aged less than 12 months. They were randomly selected from data from 1971 to 2006. Stillborn babies were included in the study
The data obtained from Scotland found that parents who lost a child under 12 months of age ran twice the risk of dying early or becoming widowed compared to parents who lost no children.
The impact of child bereavement was found to be greater on mothers, although fathers had a higher risk of early death too, the authors wrote.
In England and Wales, mothers who lost a child run four times the risk of dying within 15 years of the child's death, compared to other mothers. Even 25 years after the loss of a child, the risk of early death was 1.5 higher.
Dr. Harper said that "dying of a broken heart" does not only apply to the loss of a spouse or partner, it also happens to people who lose a young child.
The investigators had not had enough data to determine what impact, if any, suicides had on the figures. They believe bereavement may have a biological effect on the parents, such as undermining their immune system.
Dr. Harper said:

"Bereaved parents may also be more likely to use maladaptive coping strategies, such as alcohol misuse."

Harper explained that alcohol misuse may raise the risk of developing alcohol-related illnesses, or accidental injuries.
The authors added that perhaps some parents whose child is stillborn or dies early may themselves have poor health.
Dr. Harper said:

"It is imperative that cause of death be further investigated in order to establish the factors leading to increased mortality in bereaved parents."

HEALTH MANAGEMENT. Smoking marijuana not relating to obesity: study

NEW YORK | Sun Sep 11, 2011 10: 22 pm EDT
NEW YORK (Reuters) - who marijuana smoked has "the munchies," knows, that want to eat anything within reach. But a study from France has found that, surprisingly, actually less often than non-smoking, weight to put pot smokers.
Researchers led by Yann Le STRAT, a psychiatrist in the Louis Mourier hospital in Colombes, France, were found that approximately 14 to 17 percent of people reported that they smoked pot at least three days a week obese with data for more than 50,000 adults in the United States.
That compared with 22 to 25 percent obesity among people who said they had used not pot in the past 12 months.
"Initially, we thought we made a mistake," Le STRAT, adding that he said and co-author Bernard Le foll the results checked several times to ensure that they were correct.
"This is only a preliminary earnings." "It does not mean that marijuana really help to lose weight, but maybe there's a component that does."
The study, published in the American Journal of epidemiology, contain two surveys of adults in the USA-one about 43,000 people, the other about 9,300 respondents. Both had of branches of the US national institutes of health between 2001 and 2009 performed.
The larger the surveys found that 14 percent of the pot were obese smokers compared to 22 percent, the pot smoking not. Also the smaller survey found 17 percent of the pot-smoking obese be compared to 25 percent of the non-smoking.
All respondents two surveys smoked pot between four and seven percent, she said at least three times a week.
Whether she had smoked cigarettes also does not affect the results of obesity, although researchers not look at whether nutrition and lack of exercise in pot smokers and non-smokers were different.
According to an another recent survey from the substance abuse and mental health services administration is pot use on the rise in the United States. Almost 16 million US citizens, marijuana used an increase of around 15 million in 2007 in 2010.
Scientists have the role to block various molecules within marijuana smoke, high feeling, pain, and may be subject to the hunger for food in the rule provoked, explored by using pot.
Cannabinoids, molecules natural signaling chemicals in the body, similar to be believed, too stimulated to key Appetit--so much so that in 2006, a drug called rimonabant, designed to combat cannabinoids, work has been developed.
Rimonabant has been in more than 30 countries, but not in the United States, for the treatment of obesity. But the drug was pulled from shelves two years later by an increased risk of suicide among its users.
Whether cannabinoids are the only appetite stimulants in pot smoke, or other chemicals could take account of the impact, remains to be seen, the researchers say.
Other experts said that the results, which does not surprise her.
"There is no evidence of that repeatedly, body weight, can increase use of marijuana," said Vincenzo Di Marzo, Professor at the Institute of Biomolecular Chemistry in Pozzuoli, Italy, which was not part of the study.
He warned that the study does not appear that smoking pot helps you lose weight, but that it could be a starting point for future research.
Le STRAT echoed this view and warned before experiment with pot as a diet aid.
"I see people with marijuana addiction." "I hope that people will not interpret the results mean that if they use marijuana, they are to lose weight", he added. Source: bit.ly/mQOCXt

HEALTH MANAGEMENT. Study suggests that the 'Dirty' wild mice may be relevant Immunology model

Like humans, mice, the life in their natural habitat meeting be bacteria and other pathogens, which exert their immune system still the lab mice, typically in Immunology studies in triggered to most diseases. A study on natural killer cells in wild mice, who this week published the hypothesis that the operational lives of people facing and wild the willingness of the immune system can improve mice, studied in molecular ecology to combat new infections. The results indicate that the neglected traditional lab mouse model environmental factors research, that are required to fully represent the immune system of mice and men.
Natural killer (NK) cells are key players in the development of important immune system response to vaccines, infection, or cancer. However essential NK cell actions take place in the lymph nodes, and NK cells are usually not seen in lab mouse lymph nodes, if the animal is exposed to an infection. People and animals, on the other hand, port NK-cells in their lymph nodes at all times. Preben Boysen and colleagues at the Norwegian School of veterinary science and the Norwegian Institute of public health found that wild lymph nodes had mice also increased number of NK-cells, which in comparison with laboratory mice, suggesting that these wild mice human immune system more accurate than lab-mouse-based Immunology studies meet.
These results are a recently proposed hypothesis, that NK-cells need a microbial primer phase to be consistent. The increased activity of NK cell in wild mice could also the recent discoveries, NK cells carry imprints of previous microbial meets and remain for a long time as "Memory-like" cells, the previous presentation, that such cells usually ephemeral reflect immune cells. An important interpretation of these results is that the immunological research in the conventional mouse model may be important NK immune responses Miss is based, because these key cellular players will have gone through not the microbial primer, occur typically in a mouse or a human nature.

HEALTH MANAGEMENT. Bright green cats are new tool in AIDS research

CHICAGO | Sun Sep 11, 2011 1: 24 pm EDT
Cats green radiant a strain of wheat with cells, infection by a virus have to CHICAGO (Reuters) - U.S. scientists, the cat AIDS, noting that can help resist caused to prevent that the disease in cats and AIDS research in people advance developed.
The study, published Sunday in the journal nature methods, involved inserting monkey genes, that the virus in feline eggs or ova, to block before they are fertilized.
The scientists also eingefügten jellyfish gene that the modified cells luminaires have a eerie green colour-make easy to see the modified genes.
Show they are resistant to feline immunodeficiency virus, or FIV, which causes AIDS in cats taken from the cats tests on cells.
"The offers the unprecedented ability, which impact the AIDS protection genes in AIDS threatened animals," said Dr. Eric Poeschla the Mayo Clinic in Rochester, Minnesota, who led the study, in a telephone interview.
Poeschla said, that in addition to humans, cats, and to a certain extent, chimpanzees, which causes only mammals that develop naturally occurring viruses, the AIDS.
"Cats of this all over the world suffer," he said.
Such as the human immunodeficiency virus or HIV in people, FIV will fight eradicate infection of T cells.
FIV infects primarily feral cats, of which there are billions in the world, half Poeschla said. It is of bite, mostly by men, transferred to the defense of their territory, but pet cats are also affected.
People and cats are proteins, as limiting factors, to combat the usually viral infection against HIV and FIV defenseless, because potent counter weapons developed the virus. But some monkey versions of this restriction can control of virus factors and one used the team gen from the rhesus monkey.
For the team, the staff in Japan, was the trick to the monkey-gen for the constraint factor-known as TRIMCyp - cats cells against infection by the virus to block.
GREEN FLUORESCENT PROTEIN GENE
To do that it uses a harmless virus to the genes in the eggs, a process to insert that monkeys, is already mice, pigs, sheep and marmoset in other mammals.
Easier to check, what cells had the monkey-gen, the team of a green fluorescent protein gene from the jellyfish Aequorea Victoria, which glow green makes them inserted.
"We have it easy just shining a light on the animal, or under the microscope for cells."
The method worked so well that almost all descendants from the modified eggs have the restriction factor genes. And, these defence proteins are body by the cat.
The team has put two of the three original luminous green cats, the litters, a total of eight kittens, the glowing cells, as well as have created to make.
But the point is not that the generations of disease-resistant, glowing to breed cats. Rather, the team plans to study these cats as a new way to the development of treatments for HIV and the cat version of the disease.
The work researchers said several uses.
"This technology can be applied to a variety of species, of which there is a clear many applications and potential benefits are," Dr. Laurence Tiley said of the University of Cambridge, in a statement.
"It will be interesting to see what enthusiasm in cats, they receive ability and offers of HIV and the neuro-biological research communities, and other research opportunities." "A representative non-Primate animal model would be to study a fantastic new tool for HIV Pathogenesis."
Poeschla team has taken so far only cells of animals and found resistant tested against FIV. But finally they plan, set the cats with the virus and see whether they are protected.
"If you could show that you protect, which transferred these animals, it will give us a lot of information on the protection of people would," said Poeschla.
For cats result can finally be new drugs for FIV, or gene therapy, he said.

HEALTH MANAGEMENT. Major brain stent study: Experts say procedures effectively for some patients

An article in the New England Journal of medicine, says report on national institutes of health research on brain of stents, that aggressive treatment without Stenting better for high-risk patients.
But experts at the Cedars-Sinai Medical Center, who believe in the study, that this is suitable for some patients. You express concern that those who could benefit from minimally invasive placement of a mesh tube or stent blocked brain arteries open from this report can be discouraged. They say this study is a helpful start, and concerns about multiple study but not likely to understand the last word when Stenting may be appropriate, restrictions and exclusions.
"Get far greater than those generally patients in the study of received aggressive management of risk factors." Only with these heroic measures benefit the type of average patients, as have the study, ", says Patrick D. LYD, MD, Chairman of the Department of Neurology and Carmen and Louis Warsaw Chair of Neurology at Cedars-Sinai, expert on medical intervention and management of the stroke."
Michael j. Alexander, MD, Professor and clinical Chief of the Department of neurosurgery, and Director of Neurovascular Cedars-Sinai Center comments: "for certain patients - in particular for the drugs are not effective - most experts believe Stenting is a viable option." "We have many patients had had dramatic, immediate improvement in neurological function after intracranial stenting."
LYD and Alexander, the Cedars-Sinai led part of the clinical trial of 50-Center, expressed concern about this study including: sicker patients - such as those with multiple blockages of arteries or long blocks - were excluded; Some patients are probably benefit stenting. Most patients in the study had blockages in smaller arteries, which are more difficult to treat with stenting. "It is common in clinical trials of interventionellen or surgical procedures for patients of treatment to a higher rate of event" "have in the first 30 days." Long-term results provide more valid information. "Angioplasty and stenting has become commonplace in the treatment of blocked heart arteries, but Stenting in the brain is more difficult, because cerebral arteries are more sensitive than that of the heart," said Alexander, Member of the first NIH Steering Committee for this study. Evaluated the wingspan stent - the study - designed to more flexible too fragile cerebral arteries will start.
"This is the first study, which closely analyzed patient outcomes with intracranial Stenting longer-term." First trials with coronary (heart) Artery Stenting and Carotid Artery Stenting also were not very successful. However, as we could, to determine which patients are the best candidates for these treatments, and the technology has improved, they become very successful. I think the same is true of the intracranial Artery Stenting it, "Alexander said.
Alexander has more than 500 intracranial Stenting procedures and was involved in early testing of the device in the study, intrakranialer angioplasty and stenting system used gateway span. He is a consultant and device Proctor for Stryker Neurovascular, manufacturer of the gateway balloon and wingspan stent. He has no other financial interest in the company.

HEALTH MANAGEMENT. Parental advice children can sleep. HEALTH MANAGEMENT

NEW YORK | Mon Sep 12, 2011 12: 13 am EDT
NEW YORK (Reuters) - screening children to the young people in the school with better nighttime routines sleep problems and sleep strategies with parents discuss rules according to a study of Australia could.
Author Jon QUACH, at the University of Melbourne, and his team has found that if they had sleep relating to consultation of the parents, children of tend to be less sleep problems have and better sleep than children whose parents advise get study. HEALTH MANAGEMENT
The study, published in Pediatrics, was small and not show that the sleep improvements to changes in academic performance this year.
"Sleep problems are common in children of school and are treatable using... a short behavioral intervention", Quach told Reuters Health in an e-Mail. TESCO HEALTH INSURANCE
"Parents should seek advice for your child to sleep, if they are affected."
In five and, the most sleep disorders relating to the children behavior, researchers said six year-old.
"Some of them have poor sleeping habits, where become too late to bed, they have a good-night routine nor many of them have even parents for them to stay, when they go to sleep at night," said Jodi Mindell, a pediatric sleep specialist at St. Joseph's University in Philadelphia, who was involved with the study.
They have "even in this age group some night, fear" with anxiety, which may be increased, as these children begin school.
The study focuses retreating to the back-to school timeframe and children in their first year of primary school included. HEALTH INFORMATION TECHNOLOGY
Quach said, an important window for the treatment of insomnia, because children who do not sleep well more effort that sets the transition to the school, they are for academic achievement and poorer relations later could have.
Quach and his colleagues studied about 1,500 parents of children from 22 different elementary schools in Melbourne. These parents 161 said her child had a moderate or severe sleep and 108 were recruited for the study. Children with serious breathing problems sleep-related, were, for example, excluded.
Half of participating parents had followed by a phone call of two weeks later behavioral sleep strategies, to discuss the questions on the basis of their child's school, a private consultation. The other half were not additional help offered. WPA HEALTH INSURANCE
Next year the Explorer parents again over their children sleep in investigated. Six months after the first consultation, they all gave children learn an assessment.
Sleep problems tend to be in both groups resolve, but children whose parents had sleep-related advice in General, better. AHM HEALTH INSURANCE
After six months or 26 percent of children in the consultation group and in the no-Consulting Group 47% of moderate or hard sleep disorders. By a year but there was no difference, and about one-third of children in both groups had insomnia.
Children in the consultation group less resistance before going to sleep and less time had to go to bed, parents reportedly. But there was no difference in how well she determined on scientific tests to measure, reading, mathematics and spelling skills have.
Quach and colleagues found that the study was small and a follow up with more children will be required, including one for more than a year the students academic progress, tracks.
Mindell, said the study stressed a need for teachers and school psychologists, search for sleep disorders, adding that some might help really simple changes.
"For your child to bed goes, before nine - we know that this is the turning point, including read as part of the good-night routine - it calm children down helps, it gives them a priority, it helps with competence, it's all good." Then children to fall encourage asleep on their own ", she said."
Also ensure that there are no unwanted electronics in the room, added to them.
"Get the game boys RID, get rid of the computer, get rid of mobile phones," she said.

HEALTH MANAGEMENT. According to Fukushima, mother, her life fights back

By Antoni Slodkowski
Prefecture of RAJASTHAN, Japan | Sun Sep 11, 2011 9: 40 pm EDT
Prefecture RAJASTHAN, Japan (Reuters) - even before the March 11 earthquake and tsunami hit Fukushima knockout nuclear, the Aya life was a struggle.
She had divorced her abusive husband and remained even to maintain and provide for her two daughters.
Six months after their home only 9 kilometers (6 miles) of the radiation spit plant, they fled is now the 26-year old single mother barely survive. She has no job, limbo in hiding from her violent ex-husband in temporary housing, and will probably never see home.
"It feels like a hole in me has opened." My House was so important for me, and I felt sure, "Aya said that does not give her family name or disclose their exact position out of fear that her ex-husband she could find."
"It is how the time just stopped." "Since March 11, which has stopped time for me."
The tsunami left 20,000 dead or missing, made himself the world's worst nuclear disaster since Chernobyl a quarter of a century ago and forced 80,000 to evacuate.
Particularly hard hit those, who already down on their luck. There were reports of solitary deaths in lower rental service and quake affected jumped suicide rates in the regions considered.
After the disaster of Aya evacuated a high school in the vicinity, but could not go do not stay there as Noa - four-year old daughter - by a split spine and needs of special care. The older, six-year-old Kurea has no disabilities and goes to school.
"Noah's father at the time, and we went to Saitama (North of Tokyo)." He said the hospitals were up and running, so I decided to do it for Noa's sake, "Aya says how she legs puts brackets around her younger daughter, as they prepare for a trip to the kindergarten."
"He soon began, beat us." It was so crazy, I was forced to flee again. "Ignore the danger of the radiation I got back to Fukushima, Prefecture", Aya, says her daughter compress backpack.
She lives in a modest apartment in one of the Prefecture cities share the fate of tens of thousands, that six months after the disaster is not a permanent home.
Over 10,000 life in evacuation shelters remain 34,000 in hotels or with relatives or friends and 40,000 lives in live on time.
FEAR

HEALTH MANAGEMENT. Head count: running backs take hits hardest, linemen take the most

Researchers gathered data on the frequency, direction, and magnitude of head impacts from players who wore sensor-equipped helmets during three football seasons at Brown University, Dartmouth College, and Virginia Tech. The data amount to a measure of players' exposure to head impacts, which can ultimately help physicians and scientists understand how concussions occur.
Thousands of college football players began competing around the nation this week, but with the thrill of the new season comes new data on the risks of taking the field. A new study reports that running backs and quarterbacks suffer the hardest hits to the head, while linemen and linebackers are hit on the head most often. The researchers measured head blows during games and practices over three seasons at Brown University, Dartmouth College, and Virginia Tech.
The study, led by Joseph J. Crisco, professor of orthopaedics in the Warren Alpert Medical School of Brown University and director of the bioengineering laboratory at Rhode Island Hospital, documented 286,636 head blows among 314 players in the 2007-09 seasons. Crisco said the new data on the magnitude, frequency, and location of head blows amounts to a measure of each player's head impact exposure. Ultimately it can help doctors understand the biomechanics of how blows to the head result in injury.
"This allows us to quantify what the exposure is," Crisco said. "It is the exposure that we need to build upon, so that we can then start understanding what the relationships are with acute and chronic head injury."
The study appears online in advance in the Journal of Biomechanics.
Concussions and other head injuries have become a source of elevated concern in football and other sports in recent years, with various leagues revising policies to protect players better. In part based on seeing this new data, said Robin Harris, Ivy League executive director, league officials announced earlier this year that full-contact practices would be limited to two a week.
Hits by position
The new study documents the nature of head blows by player position. Players on the three teams wore helmets equipped with wireless sensors that measured acceleration in various directions. That data allowed the team of researchers from Brown, Dartmouth, Virginia Tech, and sensor-maker Simbex to discern how hard the hit was, how often each player was hit, and where on the helmet they were hit.
Crisco devised the algorithm that Simbex's Head Impact Telemetry System uses to measure head impacts. The system's development and this study were funded by the National Institute of Child Health and Human Development and the National Operating Committee on Standards for Athletic Equipment.
The data on head acceleration and hit direction are used to calculate a composite score of exposure called HITsp that researchers believe might be a good predictor of concussion. On average, running backs had the highest HITsp, 36.1, followed by quarterbacks with 34.5 and linebackers at 32.6. Offensive and defensive linemen had the lowest HITsp numbers, with 29.0 and 28.9 respectively, but along with linebackers, they were hit on the head most often. Doctors worry not only about hit severity, but also hit frequency, because repeated head impacts may cause "subconcussive" neurological damage over time.
By analyzing head impacts by position, Crisco said, researchers can help football league officials and equipment designers begin to think about ways to make players safer.
"It will allow us to begin to understand how to control the exposures," Crisco said. Controlling head impact exposure is critical, he added, because there are currently no treatments for acute or chronic brain injuries, and helmets cannot prevent injuries for all players in all situations.
One possibility could include rule changes. Another could include designing helmets for specific positions.
Crisco and his colleagues are now analyzing data about concussions during the three seasons to determine how and whether head impact exposure is associated with injury. He recently co-authored another paper about male and female collegiate hockey players, which reported that although women were diagnosed with more concussions, they sustained fewer and less severe head impacts.
Although Crisco's analysis is still underway, his insights into head impact exposure led him and co-author Richard Greenwald, a Dartmouth engineer, to write a commentary earlier this year in Current Sports Medicine Reports, in which they argued that intentional use of the head in sports must be curbed.
"We propose the adoption of rules - or in some sports, we champion the enforcement of existing rules - that eliminate intentional head contact in helmeted sports," they wrote. "When coupled with education that leads to modified tackling, blocking, or checking techniques, these rules will reduce head impact exposure and have the potential to reduce the incidence and severity of brain injury."
Crisco, a former college football and lacrosse player, said he is passionate about contact sports and believes they have many benefits.
"Hitting is an essential component," he said. "But intentional hitting with your head was never part of any sport and is poor technique."

HEALTH MANAGEMENT. ' TF beacons to illuminate way to the new Oncology tests and drugs

Scientists report development a long control desired new way that the activity of genes in the way are action to detect, which bind to the DNA in genes, proteins, cells, which normally cause everything from growing cancer often. Your report is in the journal of the American Chemical Society.
Kevin Plaxco, Francesco Ricci and colleagues found that more than 10 percent of the 25,000-30,000 instructions contain genes in the human body for this so called DNA-binding proteins. Most of these proteins are known as master regulators transcription factors (TFs). You start or stop the first step in this process, in which genes statements into action are implemented. TFs bind to DNA and genes, enable or disable. Understanding and measuring the activity of TFs is important, because they are involved with many in connection with cancer, health and disease, for example. With existing possibilities the activity of TFs is slow and cumbersome to recognize scientists, stated that barrier to overcome.
The scientists describe, development and successful testing fluorescent sensors, that they term "transcription factor lighthouses." The lamps signal the activity and the concentration of TFs directly in biological samples by moving from a dark State to a fluorescent State on binding on their specific TF. With TF beacons works easier and faster than current methods, and scientists say TF beacons of various applications in cancer, the search for new cancer drugs and other areas can have.

HEALTH MANAGEMENT. American families only $ 95 off better in 10 years because of rising health care costs

A median-income American family is only $95 per month better off today than ten years ago because rising health care costs have eliminated virtually all their income gains, researchers from the RAND Corporation revealed in the journal Health Affairs. Had health care costs risen in line with other goods and services those families would have had an extra $545 disposable income per month in 2009.
Economist David Auerbach, the study's lead author, said:

"Accelerating health care costs are a primary reason that the so many American families feel like they are just treading water financially." "Unless we reverse the trend, Americans increasingly notice that health will costs compromise their other spending options."

Between 1999 and 2009 in the United States: health care spending rose from $1.3 trillion to $2.5 trillionHealth care spending per person rose from $4,600 to just over $8,000.13.8% of country's GNP (gross domestic product) was spent on health care in 1999. It rose to 17.6% in 2009.These numbers may be sobering, but they do not translate to the daily routine of typical American families easily, mainly because health care costs are not all clearly visible, the authors wrote.
To describe the hidden burden that ever increasing health care expenditure placed on a median-income family consisting of two parents with two children, with employer-sponsored insurance from 1999 to 2009, Auerback and Dr. Arthur L. Kellermann gathered various data together from several sources.
American families can see health care costs in two ways: through the amount they have to pay every month on their private health insurance premiumThrough out-of-pocket expenditure for deductibles, drugs, copayments and other itemsHowever, the researchers say there are other less visible costs: for an employer to be able to pay a share of the worker's premium, his/her wages and other compensation are usually reducedA proportion of the family's income goes towards paying for federal and state taxes which are devoted to such health programs as Medicaid, Medicare and the military health had on annual income of $76,000 in 1999, care system the median-income family in the United States this grew to $99,000 in 2009, on increase of 30%. However, health spending increased at a considerably greater rate. Monthly health insurance for families rose from $490 to $1,115 (128%), and out-of-pocket expenses from $135 to $240 (78%).
Public expenditure on health rose by 76% at state level and 140% at federal level.
As federal tax rates dropped during the ten-year period, the portion of family's tax bill that went towards health care costs – from $345 to $440 did not fully reflect this increase.
Therefore, families had much less money to spend because of rapidly rising healthcare costs.
A typical family's income rose by approximately $1,910 during the decade. Over 40% of that went on higher health care costs. Increases in the cost of consumer goods plus non-health care taxes absorbed a further 53%, leaving the average median-income family with a mere $95 extra money in their pockets at the end of each month.
Kellermann said:

"The complex way that the United States pays for health care often obscures the consequences of health care cost growth for most American families." "This makes the challenge of controlling health care costs that much harder."

The researchers worked out that if health care costs had risen by 1% more than the annual GDP rise, the median-income family would have had $335 extra cash at the end of the month at the end of the decade, and $545 if health care costs had risen the same as the overall inflation rate during that period.
The target set by the affordable care Act is a 1% higher increase in health care spending than the increase in GDP.

HEALTH MANAGEMENT. Increases death risk in African-American women with obesity and waist size

According to a new study led by researchers from the Slone Epidemiology Center at the Boston University higher overweight and obesity in African-American women, will increase the risk of death. Cause of death in women, moreover, was a larger waist size with a higher risk the not obese. The relationship between body size and risk of death was strongest for deaths from cardiovascular disease.
The study, published in the New England Journal of medicine, Deborah Boggs, ScD, a researcher at the Slone led.
Researchers assessed the relationship of body mass index (BMI) and waist circumference risk of death over a period of 13 years of follow up in the black women's health study, an ongoing study of 59,000 African-American women in the United States. The Auditors focused on 33.916 women who had never smoked and were free from cardiovascular disease and cancer at the beginning of the study.
The risk of death was 18 percent, for every 5 units increase in BMI and BMI most from cardiovascular disease death was connected. The risk of death from cardiovascular disease was two times higher for obese women (BMI 25-29) and three times higher for obese women (BMI of 30 or higher) compared with women with a healthy weight (BMI below 25). The researchers also found that a larger waist size increased risk of death among women is associated with, who were not obese been classified; A waist size was over 35 inches a 55 percent higher risk of death.
Whereas BMI is one good estimate of the total body fat, waist size is a measure of the distribution of body fat, particularly abdominal fat. Previous research suggests that belly fat is more metabolically active, plays a role in the development of insulin resistance and can be especially harmful for the long-term health. In those who are not obese may be waist size a better indicator of risk for many health consequences.
Earlier results found that risk of death with higher BMI in the white population increased, but the limited data available on African-Americans out, pointed, increasing risk of death only at a very high level of BMI.
"Today's results show that increases the risk of death in black women with increasing BMI of 25 or more similar to the pattern in the white people", said Boggs, main author of the study. "Our results emphasize the importance for women of a healthy weight, and keep additional inches from the waist in order to reduce the risk of death."

HEALTH MANAGEMENT. Operations (Rivaroxaban) recommended for patients with non-valvular atrial fibrillation, United States

Anticoagulant Rivaroxaban (rivaroxaban) has been recommended by the FDA's cardiovascular Renal Drugs Advisory Committee for the prevention of systemic embolism and stroke in patients with non-valvular AF (atrial fibrillation). The Committee, also known as the Panel, voted 9 to 2 in favour, with 1 abstention.
The FDA (food and Drug Administration) is expected to make a final decision on September 8th. The Panel's verdict is not binding; the FDA can ignore the recommendation if it so wishes. However, this rarely happens.
Bayer Healthcare holds the rights to sell rivaroxaban outside the United States, while Janssen Pharmaceuticals, Inc. has the rights to market it inside the United States. Janssen is a Johnson & Johnson company.
Janssen had submitted to the NDA (new drug application) for rivaroxaban in the United States on January 5th this year for the prevention of stroke and systemic embolism in individuals with non-valvular AF.
Bayer has submitted rivaroxaban for market authorization for the same indication as well as DVT treatment and the prevention of recurrent DVT and PE to the European Medicines Agency (EMA). A submission has also been presented to Japanese authorities.
Rivaroxaban was approved recently for blood clot prevention after some orthopedic surgical procedures. Having approval for stroke will give access to a much greater number of patients Janssen.
Warfarin has been used for stroke prevention for over 50 years. With warfarin, doctors need to regularly measure its levels in the bloodstream, which is not the case with Rivaroxaban. However, warfarin is far cheaper.
According to Bayer and Janssen, Rivaroxaban is more convenient for patients, and has fewer side effects.
The heart has two upper chambers - the atria, and two lower chambers - the ventricles. The atria consist of a right and left atrium, and the ventricles are called the left and right ventricle. When the atria contract too rapidly and / or may, the patient has atrial fibrillation. Atrial fibrillation is the most common type of arrhythmia, which is caused when there is a disorder in the heart's electrical system. Arrhythmia is a problem with the speed or rhythm of the heartbeat.
AT affects over 6 million Europeans, more than 2.3 million Americans, and approximately 800,000 patients in Japan.
AT patients are vulnerable to the formation of blood clots in the atria. The clot can make its way through the bloodstream to the brain, where it can cause a stroke. Strokes can lead to brain damage, which in turn can result in serious physical and behavioral problems and even death.
On individual with AT is five times more likely to have a stroke compared to the general population. In fact, about one-third of AT patients do suffer a stroke.

HEALTH MANAGEMENT. Protective protein prevents joints ravaged immune system from and bones in rheumatoid arthritis

Researchers at the Northwestern University Feinberg have discovered School of medicine, why the immune cells of patients with rheumatoid arthritis are hyperactive and attack the joints and bones. The immune cells have lost their bouncer, burly protein, which is the same way keeps them in line, that noisy patrons controls a bouncer at a nightclub.
The Feinberg School team has this bouncer, a protein called P21, which prevents the immune cells are start in their destructive rampage through the cartilage and bone. If she developed scientists and injected an imitation of the protein in an animal model of rheumatoid arthritis, the disease process was stopped.
"The doorman molecule immune cells of crazy, not more", said lead author Harris Perlman, Associate Professor of Rheumatology at the Northwestern Feinberg School. "Imagine destructive customers in a bar and Bouncer says: 'You're going to behave!'" P21 is. "This discovery opens up a new avenue for future therapies, heavily used against rheumatoid arthritis."
Feinberg team in P21 showed previous studies on patients with rheumatoid arthritis were low, but the protein role was unknown. The new study, published in the journal Arthritis & rheumatism, shows role crucial protein, to keep the immune cells in check.
Currently said to stop, Perlman hyperactive immune cells can be not effective, non toxic.
To develop the new approach, tested share five different Perlman and his team, peptides, called by P21. He slipped each peptide in a "ghostly" molecule, which he injected into mice with rheumatoid arthritis-like disease. The molecule secretly infiltrated the immune cells. After the seven day trial, one of the tested peptides had reassured the overactive immune cells without toxic effects. Next, Perlman plans a 30-day trial of the same peptide to monitor effectiveness and toxicity over a long period.
Existing treatments for rheumatoid arthritis are low-level chemotherapy and corticosteroids. These are not always effective, however, and they are often accompanied by side effects. A newer class of therapy, sometimes used in combination with chemotherapy and steroids, is a biological response modifier. These are the antibody or other proteins that are produced from the hyperactive immune cells to reduce the inflammation. These Biologics work not for everyone, however, and can be associated with side effects, including the risk of infection.

HEALTH MANAGEMENT. Mother's diet influences baby's allergies

A possible link between what a mother eats during pregnancy and the risk of her child developing allergies has been identified in new research published in this month's the journal of Physiology.
The research found that if a mother's diet contains a certain group of polyunsaturated fatty acids (PUFAs) such as those found in fish, walnut oil or flaxseed the baby's well develops differently. The PUFAs are thought to improve how well immune cells respond to bacteria and foreign substances, making the baby less likely to suffer from allergies.
Until now, several clinical trials have shown that fish and walnut oil supplementation in pregnant women reduces the risk of allergy in their children, but the mechanism what unknown.
"There is intense research interest in maternally diet during pregnancy." "In the western diet, the group of polyunsaturated fatty acids that we have shown to help good function are actually disappearing our dietary intake of fish and oils is being replaced by corn nut oils which contain a different kind of fatty acid". Said Dr Gaëlle Boudry, of the INRA research institute in Rennes, France.
"Our study identifies that a certain group of polyunsaturated fatty acids known as n-3PUFAs causes a change in how a baby's well develops, which in turn might change how the good immune system develops." "These changes are likely to reduce the risk of developing allergies in later life."
The team found that supplementing a mother's diet with n-3PUFA caused the new-born's well to become more permeable. More permeable well enables bacteria and new substances to pass through the lining of the well into the bloodstream more easily A. These new substances then trigger the baby's immune response and the production of antibodies.
"The end result is that the baby's immune system may develop and mature faster leading to better immune function and less likelihood of suffering allergies," added Dr Boudry.
This research adds to previous studies which have shown that at intake during pregnancy increases of n-3 PUFAs gestational length and maturation of the central nervous system of a baby and that their performance on mental tasks also seemed to be improved in childhood.
"Other studies have found that a diet containing fish or walnut oil during pregnancy may make your baby smarter our research adds to this, suggesting such supplements so accelerate the development of a healthy immune system to ward off food allergies."
In terms of next steps, the team's findings were based on piglets research will continue to see if they translate to humans. The porcine intestine is an excellent model of the human good however, so they are hopeful that the findings can be extrapolated. The team also plans to investigate whether the apparent good function-boosting effects of n-3PUFA that they have identified in new-borns extends into later life.

HEALTH MANAGEMENT. Listeria Outbreak probe expands to three States

By Keith Coffman
DENVER | September 9, 2011 7: 16 pm EDT
DENVER (Reuters) - has expanded an investigation into a Listeria outbreak has killed at least one person with three States where was consumed potentially contaminated cantaloupe, Colorado health officials said on Friday.
The Colorado Department of public health and the environment, said in a release that the all patients recently melon ate nine confirmed cases of the gastric infection in Colorado, two suspected cases in Texas and Nebraska.
Chris Urbina, medical Chief for the Department said that officials still pursued still not, where the tainted were sold melons.
"While the investigation continues the cooker of the listeria, it is advisable for people at high risk for Listeria infection to consume of melon," URBINA said in a written statement.
At the age of 60, pregnant women and people, whose Immunsystem have weakened by disease or organ transplantation, are the most likely of the bacteria become ill URBINA said.
Because of the outbreak is gone-State, the US Centers for disease control and prevention coordinated the investigation in conjunction with the U.S. food and drug administration and the U.S. Department of agriculture.
Although Colorado has reported since early August 13 cases of Listeria associated the State to the current outbreak only nine cases.
In four other cases the melon link has excluded or laboratory results aren't yet Health Department said.
Two patients have in Colorado of Listeria last month died, but investigators can only be a dead link to the current outbreak.
Avoid people in the groups at risk for contracting the infection should unpasteurized soft cheese, chilled, smoked fish and Deli meat unless they have been heated to 165 degrees Celsius.
Healthy people are usually not affected by the bacteria. In severe cases, the infection can lead to convulsions and stillbirths or miscarriages in pregnant women.

HEALTH MANAGEMENT. Enzyme could be target for the treatment of smoking, alcoholism at the same time

An enzyme that is displayed, a role in controlling the brain response to nicotine and alcohol in mice may be a promising a drug, which would at the same time deal with smoking, and alcohol abuse in humans, according to a study by researchers of the Ernest Gallo clinic and Research Center, San Francisco joined with the University of California,.
In the course of four weeks mice genetically so is missing the gene for protein kinase C (PKC)-Epsilon consumes less a nicotine-containing water solution than normal mice and were less likely to a Chamber back, in which she had given nicotine.
On the other hand, normal mice steadily grew their consumption of nicotine solution, while the mice PKC Epsilon is not missing.
The study was conducted by Gallo, senior associate director and investigator Robert O. brass, MD, UCSF Professor of Neurology and Gallo researchers Dr. Anna M. Lee.
Binds nicotine to a certain class of Nicotinic Receptors in normal mice, as in humans is neurons released by dopamine in the brain causes on dopamine. Dopamine creates a feeling of joy and so calls for a sense of reward. Lee and brass found that mice without PKC Epsilon has a lack of these Nicotinic Receptors.
The study is in the online early Edition of the proceedings of the National Academy of Sciences for the week of 12 September 2011.
The finding complements earlier research in brass found that mice genetically PKC-Epsilon enzyme deficiency to less alcohol than normal mice potion and were averse to a Chamber, where she had been alcohol again.
"This could mean that these mice of nicotine or alcohol, not the same feeling of reward get," brass said. "The enzyme looks like it the part of regulating the reward system, which includes these Nicotinic Receptors." The reward system is a complex of areas in the brain, which call for nicotine, to influence alcohol and other addictive substances.
The next step in the research, brass, said would be to develop compounds that inhibit PKC Epsilon. The ultimate goal, he said, would be drugs, which could be used "through its contribution to the edge of searches for people on some of which will demand their reward."
The research was U.S. through grants from the public health service and the Canadian Institutes of health research, and funded, supported by California for medical research on alcohol and drug abuse by UCSF.
The UCSF-affiliated Ernest Gallo clinic and Research Center is one of the world's preeminent academic centres for the study of the biological basis of alcohol and substance use. Gallo center discoveries possible molecular targets for the development of therapeutic medicines through preclinical and proof-of-concept studies extended.
UCSF is a leading University, promoting health worldwide through advanced biomedical research, graduate training in life sciences and health professions, and excellence in patient care.

HEALTH MANAGEMENT. Study clouds image on Omega-3 fatty acids and heart health

By Adam Marcus
NEW YORK | September 9, 2011 1: 16 pm EDT
NEW YORK (Reuters Health) - fatty acids such as food fish and certain plants can not prevent that heart disease as well as previously believed, a new study concludes.
Danish researchers who analyzed the diet of nearly 3,300 people found, that, usually people who reported, eat more fatty acids not less likely in time for the development of ischemic Herzkrankheit--d. h. supply of blood to the Herzen--as humans reduced, which consumes less of nutrients.
However, women who ate the Omega-3 fatty acids, often in fish and fish oil supplements, has apparently benefit. They had almost 40 percent lower risk of developing heart disease than women, which, in the least fat, food insights that are displayed in the American Journal of clinical nutrition.
The study of "important questions about the interactions of these nutrients with heart health, solves", said Alice Lichtenstein, Director of heart-circulation nutrition laboratory at Tufts University. But it shows show, studies, difficult to extrapolate the concentration on the eating habits of a single country are.
"Because food is ecological specific, you only can assume in a population observed necessarily right for another", said Lichtenstein Reuters Health.
U.S. giving food and Drug Administration said in 2004 "supportive but not conclusive" evidence that a person of Omega-3 fatty acids may reduce risk of heart disease. The agency recommended that people consume no more than three grams per day of the substance, with not more than two grams of which from dietary supplements.
In addition to Omega-3 fatty acids the current Danish study saw the effects of linoleic acid, and a similar substance, alpha-linolenic acid-both plant-about the risk of heart disease in 3.277 men and women live in the greater Copenhagen originate.
No topics had diagnosed with heart problems, when entering the study, gathered information about their eating habits, exercise and other lifestyle patterns.
After an average of 23.3 years ordinarily 471 participants developed ischaemic heart disease. -But only women who reported eating the most Omega-3 fatty acids some like 11.2 grams per day-seemed from the nutrient benefit. The risk of heart disease was 38% lower than that consumed women, less than 0.2 grams per day, the researchers found.
"High intake of Omega-3 fatty acids a significant cardioprotective effect among women," said MIA Sadowa Vedtofte, the National Institute of public health at the University of southern Denmark in Copenhagen and co-author of the study.
Vedtofte said, that men who ate more Omega-3 fatty acid-rich foods seemed win also protect against heart disease, but that the statistical differences were small, so that the effect could be due to chance. To answer the question more clearly, she added, which would have required more people study.
The estimated average daily intake of fatty acids by study participants was 1.2 g for women and 1.6 g for men, according to the researchers. This is slightly higher than in other studies, which have us fatty acid effects, but at least for women, equal to the recommended minimum.
Vedtofte said that she and her colleagues were "a little surprised" that the vegetable fatty acids, which she studied not appeared, to prevent heart disease.
The results of this study does not prove that the Omega-3 fatty acids benefit prevent heart disease, the significant also in women. Another factor that goes along with a fish-rich diet could for example also at work.
Lichtenstein said that should change basic advice for Americans not: a diet, rich in little meat, fruit and vegetables to the food. Even if fish oil proves not to protect against heart disease, she added, is "it no…" Reason for not including fish in the diet. "It can be a food that are displaced rich in saturated fatty acids."
Lichtenstein notes that the Danish considered only whether fatty acids against heart disease could protect study, whether they help with established in the prevention of cardiovascular events such as heart attacks and strokes in people were not heart disease.
"There are data showing that for people with established disease, they benefit" of supplements, she said.
A large US study with 20,000 volunteers is VITAL study (bit.ly/P3UO4), now under way examined whether vitamin can protect D and Omega-3 fatty acid supplements against heart disease, cancer and strokes in people with no history of such problems.

HEALTH MANAGEMENT. SPX-106T treatment leads to significant reductions in serum VLDL and LDL cholesterol in mice

Spherix incorporated (NASDAQ: SPEX) an innovator in the field of biotechnology for the treatment in diabetes, metabolic syndrome and atherosclerosis and provider of technical and legal advisory services on food, Supplement, biotechnology and pharmaceutical companies announced, given that achieves statistically significant reduction of the VLDL and LDL cholesterol, if genetically modified his drug candidates SPX-106, mice Dyslipidemia vulnerable in combination with Dtagatose (SPX-106T) for nine weeks. The Aortas these mice showed also cuts in the amount of atherosklerotische lesions lesion measured area in response to the treatment. This lipoprotein analysis and lesion results form the last data from the study, whose previous triglycerides result first on June 2, 2011 was announced.
Treatment of animals, with a series of low doses of SPX-106T twice daily significantly reduced VLDL by 35% (of 127 mg / dl to 82 mg / dl) and LDL by 18% (from 141 116 mg / DL) (p = 0.05). Importantly, reduced the same therapy also atherosclerotic lesions range in the aortic arch to less than half the value of the untreated group (chart available at http://www.spherix.com/pdf/press/PRgraphic9-12-11.pdf). The aortic arch is the region where ship first developed disease. The thoracic aortic include more studies and models fully developed into the high serum triglycerides, illness of spreads on the ship of the aortic arch. The study was not driven on an atherosclerosis endpoint and the Aortas was made for the post-hoc analysis, when it turned out the effectiveness of the SPX 106T reduction of triglycerides and cholesterol.
D-tagatose alone and combination judged this year initiated Spherix the preclinical development of SPX 106T as a treatment for hypertriglyceridemia in one arm of a trial. The first studies that specifically test for SPX-106T are nearing completion and results will be this fall. The company plans to launch an initial human efficacy to study in the first quarter of 2012. Rapid progression in the clinic is made possible by the experienced team at the company.
"Two global clinical trials for a diabetes indication, that only successfully concluded, has Spherix to design staff and running new Dyslipidemia suffer much faster than other companies of comparable size," notes Claire Kruger, Chief Executive Officer of Spherix Dr. "The preclinical pipeline of our Biospherics subsidiary can be expanded quickly in the clinical phase, because the company can perform successfully several studies at the same time."

HEALTH MANAGEMENT. Analysis: Forecast bad for UN chronic disease meeting

LONDON (Reuters) - ten years to commit to the fight against AIDS, the United Nations takes on an even bigger pile of Mörder--common chronic ailments-in what design is up for a bruising battle between big business, Western Governments and the world's poor.
Tobacco, food and drink companies are in the firing line for peddling products, accused in connection with cancer, diabetes and heart disease while politicians in the rich world, in the absence of a fixed goals or means the appropriate against provide.
"This is an opportunity generation." Rebecca Perl the World Lung Foundation (WLF) we have millions of life here, and it said is a disgraceful and immoral could save that industry lobbying short-term profits to a public health disaster has put, "told of Reuters." WLF participates in irritable preliminary talks for several months.
The fear is that the large company has successfully lobbying rich Governments only half-heartedly in non-communicable diseases or NCDs, fight despite predictions that they paralyze the health systems of developing countries could be.
A bit a short-term financial requires such as climate change, prevention and treatment of non-communicable diseases affluent Nations and multinational companies hours to prevent that overwhelmed poor countries in the future.
Fears grow in these strict times already, that a high-level UN Conference in New York on September 19-20-only the second in the Centre of the disease after an AIDS in the year 2001-could be a flop.
The collection includes scores of delegates of the UN Member States, including about 20 head of Government as well as representatives of the public health groups, non-governmental organizations, the private sector and science.
After a draft of political declaration, that are the foundation of the United Nations think many platitudes but few concrete commitments on NCDs contains close to the negotiations.
Ann Keeling, Chairman of the NCD Alliance, which groups of 2,000 health organizations from which all over the world, said "There is no strong and temporally fixed commitments there," the news agency of Reuters. "It's a big disappointment from this point of view."
NOT ROCKET SCIENCE
The extent of the problem is immense. Some 36 million people die each year from NCDs--about 80% of them in poor countries where prevention programmes are virtually non-existent, and access to diagnosis and treatment is extremely limited.
As a result, death of NCDs are almost twice as high in poor countries as in the industrialized world.
Prevent that outrun this Todesfälle-- or at least a good part - is not rocket. A simple improvement enables proven measures such as the reduction of smoking, diet, drugs available and promote the use could tap a huge hole in this number.
"It is a common history, the cancer, cardiovascular, diabetes and respiratory medicine to tobacco, alcohol, diet and General-links and that's where we have the most cost-effective impact", says David Kerr, President of the European society for medical oncology.
The key points are money, goals and control.
Complete a billion people from lighting, or to prevent every day cheap medications such as aspirin and Statins, heart attacks and strokes may be less expensive, but the repayment does not quickly and it is unlikely that many votes to win.
"The time horizon for return on investment is very long and many political horizon." So it is difficult to require people to this kind of resources, ", says Gordon Tomaselli, President of the American Heart Association."
The NCD Alliance says spending $9 billion a year on tobacco control, food risks would advice and treatment for people with heart avert millions of premature deaths in this decade.
That's a lot? Compared to care for HIV patients in developing countries already costs by 13 billion per year.
In contrast to combat AIDS, which UN focus was ten years ago, the price of drugs of less is a problem here, as many as cheap generic drugs are available, although there are disputes about the costs for some more products expensive such as insulin.
STUBBING FROM TOBACCO
The sharpest concentrated themselves this time on fatty foods, sugary drinks and--in allem-- the tobacco industry, the World Health Organization Director General Margaret Chan was described as "an industry that has lots of money and no scruples, for use in the insidious as possible."
With tobacco, if the development however, that public health lobby says nothing else does the UN session, it should be predicted to kill more than one billion people of this century at least a smoke-free world of one of its central objectives.
Smoke alone causes one of three cases of pulmonary diseases, one of four cases of cancer and in 10 cases of heart disease, says Perl. "So what a bang, get for your money there, to look for."
Conflicts Governments find it hard. Japan tobacco is of, for example, 50 percent owned by the Japanese Government, and the massive profits U.S. cigarette to strengthen the US economy manufacturers.
China, the world's male smokers, the combination of taxes and sale of China national tobacco houses a third-all State Office-account for about 9 percent of annual tax revenue of the Government.
This is one reason more, according to Paul Lincoln of UK National Heart Forum and Jaakko Tuomilehto, an epidemiologist at the University of Helsinki, hiking tobacco taxes, advertising to put the brakes and insist on health warnings graphic.
"There are no excuses," Lincoln said. "We have the know-how." "The challenge for public health as ever and ever is to overcome the ideological and vested interests."
Tuomilehto is more stump: "it is a crazy thing to have a product in the shops, the every second consumer-it kills is madness."

HEALTH MANAGEMENT. National forests provide public health benefits

More than 170 million people visit national forests for recreation each year. And physical activity in connection with these visits 290 billion food calories. The is enough of pommes-frites-end end of the Moon and back - twice - according to a study in the journal of forestry.
During the most recent strategic plan the U.S. forest service includes conservation and more opportunities for leisure activities in the open air, are the benefits of exercise and leisure activities also by President Obama America's outdoor initiative, Americans with their landscape, and the first lady's move recognized outside campaign.
But how exactly are our national forests, so people, to develop a healthier lifestyle? A recent study may show some answers.
"We the extent that national forests use could be for the public health, by the estimate of net energy spent on a range of outdoor activities involved, the national forest of the visitors studied country," explains research Forester Jeff Kline. "We have this by the combination of data that describes national forest visitors rest in the free activities with data, the characterization of the calories consumed with any kind of physical activity."
Kline, a scientist with the forest service Pacific Northwest research station, and Oregon State University co-authors, Randall Rosenberg and Eric white, recently published their findings in the September issue of the journal of forestry. In the article "A national evaluation of physical activity in U.S. national forests," holds national forests to Americans, the guidelines for regular physical activity, which laid down by the centres can meet and prevention for disease control.
Main findings of the study are: walking, hiking, downhill ski, fishing, relax, camping, relax, and driving pleasure are the primary activities for two-thirds (68 percent) of all visits to the national forests. Annual energy investment in national forest recreation are 6.8 million adults and almost 317.000 children meeting the Centers for disease control and prevention guidelines regular aerobic physical activity for a year. The distribution of these health benefits vary with close and income. 52 Percent of rest visits of people that are within of 60 miles a national forest of life. These "local" visitors are rather lower household income groups as a non-local visitor, with 45 percent earn less than $50,000 per year compared to 25 percent for non-local visitors come from.
National forest in the Western States the largest share of all rest in the free visits (75 percent) and related net energy expenditure (75%). However provide national forests in the Northeast and Southeast proportionally more net energy expenditure, because they are generally closer to major population centres towards the West, and their visitors have more intensive physical activities.
