FDA links new blood clots birth control drugs

WASHINGTON (AP) - concerns of security with the popular birth control pill as yaz increased federal Thursday that scientists of Health reported that the drug from Bayer and other newer birth control treatment appear to increase the risk of dangerous blood clots more older drugs.

A new study published by the Food and Drug Administration reviewed the medical history over 800,000 women U.S. takes different forms of control of births between 2001 and 2007. On average, women taking Yaz had 75% more likely to end up with a blood clot than women older birth control medications.

YAZ contains estrogen with a synthetic hormone of next generation called drospirenone, who is known to increase the level of potassium in the blood. FDA compared the medical records of women taking the drug with those who take the old drug levonorgestrel.

YAZ, Yasmin and related pills containing drospirenone of were free of second-best-selling Bayer to $ 1.6 billion in global sales last year.

In 2009, the FDA has taken an unusual step order Bayer to run corrective on Yaz TV advertisements, stating that the ability of drugs exaggerated the drugmaker marketing campaign to prevent acne and premenstrual syndrome.

Bayer Healthcare, a division of the German conglomerate, it says "currently assessing this publication and cannot comment on at this time."

The Agency also reported complications higher in women using the Ortho Evra of Johnson & Johnson and ring patch vaginal Nuvaring of Merck & Co. Inc. These drugs combine estrogen, which is present in all birth control pills, with two other synthetic hormones in the last decade.

The FDA said it has not reached a final conclusion on the safety of the drugs but will hold a meeting with scientific advisors on 8 December.

The consumer safety advocates have criticized the Agency of the latest and most expensive birth control drug approval when cheaper, generic medicines with established security records are widely available.

"At some point we must ask why the FDA continues to approve drugs that are less safe and have no advantage over drugs already on the market," said Dr. Diana Zuckerman, President of the National Centre for women and families, a group of consumers for women's health issues. "With all these different birth control options, why take the more expensive that can kill you?"

Recent studies have reached different conclusions about the risks of contraceptive pills more recent.

A study published earlier this week on more than 1 million Danish women found that women taking Yaz and other newer drugs have twice the risk of blood clots as women taking the hormone levonorgestrel older. The findings published Tuesday in the British Medical Journal.

However, two studies published in 2007, conducted as part of the regulators FDA postmarketing requirements or European, have not found any difference in clotting between comparable groups.

Pills of birth control containing drospirenone include Yaz, Yasmin, Bayer's Beyaz, Safyral; Sandoz Syeda and Loryna; as well as Ocella Barr, Watson Pharmaceuticals Zarah and Loryna of Teva Pharmaceuticals laboratories.

Shunning water linked to high blood sugar

NEW YORK | Mon Oct 24, 2011 3:22pm EDT

NEW YORK (Reuters Health) - People who drink less than a couple of glasses of water each day may be more likely to develop abnormally high blood sugar, a new study suggests.

When someone's blood sugar levels are high, but not high enough to fit the definition of diabetes, doctors often consider that person to have "pre-diabetes" -- which puts them at risk of developing the disease itself.

In the new study, adults who drank only half a liter of water -- about two glasses -- or less each day were more likely to develop blood sugar levels in the pre-diabetes range, versus people who drank more water.

But whether simply drinking water will cut your risk of blood sugar problems is still up in the air.

The findings show a correlation between water intake and blood sugar, but do not prove cause-and-effect, said senior researcher Lise Bankir, of the French national research institute INSERM.

Still, it is plausible based on biology, Bankir told Reuters Health in an email.

A hormone called vasopressin is the potential missing link, according to the researchers.

Vasopressin -- also known as antidiuretic hormone -- helps regulate the body's water retention. When we are dehydrated, vasopressin levels go up, causing the kidneys to conserve water. But research suggests that higher vasopressin levels may also elevate blood sugar.

There are vasopressin receptors in the liver, the organ responsible for producing glucose (sugar) in the body, Bankir explained. And one study found that injecting healthy people with vasopressin caused a temporary spike in blood sugar.

"There are good arguments to suggest that there could be a real cause-and-effect relationship in the association we have found," Bankir said, "but this is not a proof."

The findings are based on 3,615 French adults who were between the ages of 30 and 65, and had normal blood sugar levels at the outset. About 19 percent said they drank less than half a liter (17 ounces) of water each day, while the rest drank up to a liter or more.

Over the next nine years, 565 study participants developed abnormally high blood sugar and 202 developed type 2 diabetes.

When the researchers looked at the participants' risk according to water intake, they found that people who drank at least 17 ounces of water per day were 28 percent less likely to develop high blood sugar than those who drank less than that amount.

There was no strong statistical link between water intake and risk of developing diabetes, however.

One obvious explanation for the connection with high blood sugar would be that people who drink little water may instead be reaching for sugary drinks -- which could lead to weight gain and impaired blood sugar control.

But Bankir and her colleagues accounted for sugary drinks and alcohol, as well as people's body weight at the start of the study, their reported exercise levels and certain other health factors. And the link between low water intake and high blood sugar persisted.

However, they could not account for everything, including generally healthy or less-healthy eating habits.

"Healthier behaviors correlating with higher water drinking could account for the observed association," the researchers write.

As for why there was no link between water intake and diabetes itself, Bankir said that the number of diabetes cases in the study was "too small to get a significant result." A larger study might have been able to detect a statistically significant link, she noted.

Further studies are needed to confirm the findings on blood sugar, according to Bankir.

But for now, she said, replacing sugary, high-calorie drinks with water would be a good idea for anyone. "In Western countries, the consumption of sugar is surely too high and contributes to obesity," Bankir said.

"Drinking less of them (sugary drinks) and more pure water can only be good in my view," she said.

Blood vessel condition tied to MS, with caveats

AppId is over the quota
AppId is over the quota
By Genevra Pittman

NEW YORK | Mon Oct 3, 2011 12:35pm EDT

NEW YORK (Reuters Health) - A new analysis of past studies concludes that there seems to be some link between multiple sclerosis and narrowed head and neck veins -- but more research is needed to be sure.

The report, funded by Canadian Institutes of Health Research, is the latest addition to a controversy that has led some MS patients to demand a risky treatment for the blood vessel condition while scientists clamor to figure out whether or not it causes MS -- or if it even exists at all.

"The message in some ways I'm sure is kind of frustrating," said Dr. Andreas Laupacis, the lead author of the new report from St. Michael's Hospital in Toronto.

"There's some tantalizing evidence that there might be something here, but we still don't know."

The authors of the study were cautious because they could only find eight studies that have looked at how common the condition, known as chronic cerebrospinal venous insufficiency, or CCSVI, is in people with and without MS.

LINK QUESTIONED

Italian researchers first proposed in 2009 that MS, typically thought of as a disorder of the immune system, might actually be caused by blood vessel changes.

Dr. Paolo Zamboni's team found signs of CCSVI on every ultrasound of patients with MS -- and in no "control" subjects without the disease.

Their theory was that veins bringing blood from the brain and spine back to the heart sometimes become too narrow, making blood leak back into the brain tissue. That could trigger inflammation, eventually causing the balance and muscle problems seen in MS.

But since then, other scientists haven't been able to show the link between MS and CCSVI quite as convincingly.

To assess the current state of the evidence, Laupacis and his colleagues analyzed the eight studies -- including Zamboni's -- that have compared the frequency of CCSVI in people with and without MS.

Those studies involved anywhere from 10 to 310 patients with MS and a similar number of controls.

The researchers found that people with MS were indeed more likely to have the narrow blood vessels -- about 13 times more likely. And when they removed Zamboni's original study from the mix, the remaining seven studies still showed that CCSVI was almost five times more common in people with MS than without.

But there was a huge range on a study-by-study basis -- including one study that didn't see evidence of blood vessel changes in any of 76 people with or without MS.

That could be because not everyone agrees how to read ultrasound tests to look for those changes, or is trained to see them, researchers said.

"It may well be that the different groups are using different ultrasound techniques," Laupacis told Reuters Health. "It's not a straightforward kind of test."

BIAS POSSIBLE?

It's also possible that bias may have unknowingly crept into some of the CCSVI diagnoses, researchers said, if the investigator reading the ultrasound knew which images belonged to people who did or didn't have MS.

Laupacis said that more research is being done that should clarify the picture on how CCSVI and MS are related. Even if the narrowed blood vessels do show up more frequently in people with MS, though, it doesn't mean that a procedure to prop open those vessels, called liberation surgery, would also be a cure for MS symptoms. That surgery comes with a risk of bleeding and infection.

"Just the fact that (CCSVI) is more frequent in people with MS, it might mean that it causes MS. It might mean that it's a consequence of MS," Laupacis said.

"It's a critical next question to be grappled with," said Dr. Robert Fox, an MS researcher from the Cleveland Clinic, who wrote a commentary accompanying the study in the Canadian Medical Association Journal. "If there is an increased risk of CCSVI in patients with MS, what do we make of it?"

Both Laupacis and Fox have consulted for or received funding from pharmaceutical companies that make MS drugs.

Fox said that he often finds patients with MS keep themselves a bit dehydrated, because otherwise they have to go to the bathroom frequently -- and that dehydration might affect how the blood flow in their veins looks on an ultrasound.

Or, "Maybe some of these findings on ultrasound just have to do with a sick brain," he told Reuters Health.

Fox said that until those questions are answered, people with MS shouldn't get an invasive procedure that has unclear benefits.

"I fear that some patients will say this is a vindication of the CCSVI theory," Fox said. "We're still a long way away from feeling that this intervention should be recommended for MS."

Concerns over A&E blood testing

AppId is over the quota
AppId is over the quota
23 September 2011 Last updated at 00:06 GMT By Adam Brimelow Health Correspondent, BBC News Blood test Can doctors take a blood sample? Scientists say doctors need better training to avoid mistakes in blood samples taken in hospital A&E departments.

The warning from the Association for Clinical Biochemistry follows an audit at Birmingham City Hospital.

The trust has put in place extra training, but the ACB says this is a problem across the UK.

The College of Emergency Medicine says it is essential that staff use the right technique to collect blood.

Blood test results are often key to assessing patients when they arrive in A&E. But staff are frequently working under extreme pressure.

The ACB is worried that this contributes to errors when they take blood samples.

The concerns are highlighted by the Birmingham audit of samples collected by a range of junior doctors and nurses.

Urgent cases

In the study, published in the Annals of Clinical Biochemistry, the researchers followed the collection of 50 samples from some of the most urgent cases, over a two week period.

More than half were taken using the wrong equipment. They should normally by collected into vacuum tubes with special needles rather than using syringes which can damage fragile blood cells.

The researchers also found that about half the samples were mishandled for testing, raising the risk of contamination.

It sounds a bread and butter procedure but it is very important that it is done correctly, safely and consistently. We need to ensure there is the right level of expertise. ”

End Quote Dr John Heyworth President, College of Emergency Medicine The trust has arranged extra training and guidance for its A&E staff. The director of pathology at the hospital, Dr Jonathan Berg, who helped to carry out the study, says good technique is vital to ensure the tests reflect the true status of the patient.

"Junior doctors have surprisingly little training in taking blood and have a love of still using syringes which cause major problems and this is very easy to correct with a simple training programme. This is an issue right across the country".

The director of scientific affairs at the ACB, Dr Robert Hill, says there is a need for better training.

"The compromises to specimen quality made in A&E when attempting to rush through investigations clearly put some patients at risk, so fixing the problem requires more than just identifying a culprit.

"Solutions must include monitoring the competence of those taking blood during their training period and discouraging those whose lack of practice prevents them from doing it properly."

'Bread-and-butter' procedure

The study is being presented at the annual conference of the College of Emergency Medicine, which represents A&E doctors in the UK and the Republic of Ireland.

The college's president, Dr John Heyworth, says the paper is "universally relevant" to all A&E departments.

"It sounds a bread-and-butter procedure but it is very important that it is done correctly, safely and consistently. We need to ensure there is the right level of expertise.

"I think it is always seen as so routine, there is not enough focus on it as a technique for formal review and training."

The chairman of the BMA's Junior Doctor Committee, Dr Tom Dolphin, also welcomed the study.

"Emergency Departments are high pressure environments where junior doctors have to take blood in an efficient, timely manner.

"Bloods can be taken in a variety of ways and this study highlights some consequences of the choices faced by junior doctors when taking blood.

"Incorporating the findings of this research into training for junior doctors and medical students would be helpful if we are to reduce some of the issues that can arise from blood sampling."

Blood vessels made on 3D printer

16 September 2011 Last updated at 10:49 GMT Katia Moskvitch By Katia Moskvitch Technology reporter, BBC News Artificial polymer vessel Artificial blood vessels could help those in urgent need of an organ transplant Artificial blood vessels made on a 3D printer may soon be used for transplants of lab-created organs.

Until now, the stumbling block in tissue engineering has been supplying artificial tissue with nutrients that have to arrive via capillary vessels.

A team at the Fraunhofer Institute in Germany has solved that problem using 3D printing and a technique called multiphoton polymerisation.

The findings will be shown at the Biotechnica Fair in Germany in October.

Out of thousands of patients in desperate need of an organ transplant there are inevitably some who do not get it in time.

In Germany, for instance, more than 11,000 people have been put on an organ transplant waiting list in 2011 alone.

To make sure more patients receive these life-saving surgeries, researchers in tissue engineering all over the globe have been working on creating artificial tissue and even entire organs in the lab.

But for a lab-made organ to function, it needs to be equipped with artificial blood vessels - tiny and extremely complex tubes that our organs naturally possess, used to carry nutrients.

The individual techniques are already functioning and they are presently working in the test phase”

End Quote Dr Gunter Tovar Fraunhofer Institute, Germany Numerous attempts have been made to create synthetic capillaries, and the latest one by the German team seems to be especially promising.

"The individual techniques are already functioning and they are presently working in the test phase; the prototype for the combined system is being built," said Dr Gunter Tovar, who heads the BioRap project at Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB in Stuttgart.

Elastic biomaterials

3D printing technology has been increasingly used in numerous industries, ranging from creating clothes, architectural models and even chocolate treats.

But this time, Dr Tovar's team had a much more challenging printing mission.

To print something as small and complex as a blood vessel, the scientists combined the 3D printing technology with two-photon polymerisation - shining intense laser beams onto the material to stimulate the molecules in a very small focus point.

The material then becomes an elastic solid, allowing the researchers to create highly precise and elastic structures that would be able to interact with a human body's natural tissue.

So that the synthetic tubes do not get rejected by the living organism, their walls are coated with modified biomolecules.

Such biomolecules are also present in the composition of the "inks" used for the blood vessel printer, combined with synthetic polymers.

"We are establishing a basis for applying rapid prototyping to elastic and organic biomaterials," said Dr Tovar.

"The vascular systems illustrate very dramatically what opportunities this technology has to offer, but that's definitely not the only thing possible."

HEALTH MANAGEMENT. Blood lipids suggest that online individual nutrition not effective

Lively like lifestyle and waist greater; many people contact online nutrition programs. Promoting healthy eating behaviors identified computer tailored nutrition and education as a promising education health strategy, especially in the promotion of lower fat intake. A study in the September/October 2011 issue of the magazine of healthy nutrition education and behavior shows tailored education with empirical data based on the level of cholesterol and lipids but no evidence for the effectiveness of this computer.
Investigators from the Vrije Universiteit Amsterdam, the University of Maastricht and the Erasmus University of Rotterdam in the Netherlands evaluated the effectiveness of a computer tailored intervention to reduce the fat intake to determine 442 healthy Dutch adults. Instead of recording, looks even dietary callbacks for the evaluation of the fat the part size errors, unrecorded and socially desirable answers distorted can be, the researchers evaluated a reliable result - blood lipids (HDL, total and LDL cholesterol and triglycerides). The computer program to reduce the intake of saturated fat had no effect on the blood values.
DRS. Willemieke Kroeze, PhD, and Johannes Brug, PhD, and Professor, and at the free University, to explain, "computer tailored intervention with a single dose to reduce the (saturated) fat consumption, for which meaningful impact based on self reports was reported, not sufficient to produce detectable changes in blood lipids in the current study." When asked how to improve the results of the consulting online beat nutrition advice websites, Dr. Kroeze research methods "to the feasibility of the lens impacts the computer tailored nutrition education measures for primary prevention in real settings to increase." "Moreover, strategies should be developed to apply tailored measures and social interaction in the intervention to improve the level and duration of the computer."
This study documents the importance of the identification of the main factors to change the influence on the ability of individual, dietary behaviors in particular by online nutrition and education. It demonstrates the importance of the critical evaluation of the nutrition education interventions often developed as online as cost savings and place, to extend the range of the program.

HEALTH MANAGEMENT. Study casts a wider net for risky blood pressure in children

NEW YORK (Reuters Health) - could more children than previously assumed his risk of dangerously high blood pressure, with more than a quarter with blood vessels, which look like the much older, according to a new study.
Since there is a theoretical possibility that some of these children, a stroke or a heart attack, which might suffer down road, say the researchers, that the results mean that all children should their blood pressure measured.
"I believe it is important that everyone for high blood pressure, is shown," said Dr. Karen Redwine Arkansas Childrens Hospital in little rock, which the results in the journal of Pediatrics are displayed.
"The overall rate for the development of high blood pressure, if you are a teenager is still very low," added to them, in an interview with Reuters Health. "But it is a subset of people, the development of high blood pressure somewhere between two and five times, that is, and many of those are children, now normally would apply."
These children have slightly increased blood pressure and diagnosed with so-called "Prehypertension." The label is disputed, however, because no disease to describe it - it is a risk factor for the development of later high blood pressure, which itself is a risk factor for heart disease.
An expert, who said not part of the new study he worried it could be used, to push drugs without evidence, that they do something good children.
"What me a little worried is that they are talking about the pharmacologic therapy,", said Dr. Curt D. Furberg, expert on heart disease prevention and drug safety at Wake Forest Baptist Medical Center in Winston-Salem, North Carolina.
"If I me the author list, it is one of the Bristol-Myers Squibb," he added. "Pharmaceutical companies want to increase their market." "In this area sense not taking into account the healthy young children for pharmacological therapy."
The national heart, lung and Blood Institute in 2004 defined Prehypertension in children as a top blood pressure number between 120 and 139 or a lower number between 80 and 89. high blood pressure starts at 140 over 90.
If changes of lifestyle such as cutting down on salt and exercise sufficient to control high blood pressure in children, NHLBI advises drugs to try.
In adults the ups hypertension of the risk of stroke and heart attack a few percent. However, for children, the NHLBI recognizes that the long-term effects unknown are with high blood pressure for children, as are the side effects of drug treatment.
"In my mind, there are many more pressing issues in medicine as a screening for hypertension among young people, where we don't even know if treatment is useful," Furberg, Professor of public health, told Reuters Health.
The new study is an attempt, estimate how often children with Prehypertension further to develop full-blown high blood pressure or hypertension.
Development of data from a large test study - sponsored by pharmaceutical companies-at Texas schools, found Redwine and colleagues, that 11 of 1,006 students developed high blood pressure during the study.
This corresponds to a rate of 1 in 200 young people each year. Although the rate for children with Prehypertension appeared similar, a broader definition tripled created by Redwine and her colleagues nearly the rate.
After only a blood pressure higher than normal group a child in the "at risk" would set the new definition.
Until now, Redwine, explains to doctors think that a high blood pressure measurement only a Zufall--could be because the child nervously or somewhat ill was used.
Now, said she, "when it is raised only once, then you must observe and monitor it."
Currently, not the NHLBI recommend drug therapy for children with Prehypertension. But the new report suggests the investigating of the use of drugs in the "endangered."
According to the Texas screening study could that be, more than 26 percent of U.S. teenagers with the new definition-including healthy children who are not overweight.
Furberg and other critics is Prehypertension--not to mention the extended definition in the new students-a concept that comes with over slide diagnosis, over treatment and wasteful expenditure.
He said "That's what the industry is trying to do, to get people to drugs,". "they insist that for adults, and now they seem to children, which is tedious."
Redwine neutralized, although their co-authors at Bristol-Myers Squibb is busy, not drug use in children with Prehypertension are in favour of her report.
"It is not the point to say that they have to be," said Reuters Health.
The US preventive services task force, a State-sponsored group of Experts recommends screening adults for high blood pressure. It is currently the guidelines 2003 updated for children and young people, who pointed out that the evidence is not sufficient to weigh the harm and the benefits of screening children.
