Bedbugs know no social boundaries as complaints in NY increase

DateWednesday, July 28, 2010 at 05:27PM

New York to spend big to kill bloodsucking guests


NEW YORK (Reuters) - In the city that never sleeps there is one increasingly busy nocturnal resident who New York wants to evict -- the bedbug.

The city announced plans on Wednesday to spend $500,000 raising awareness of the tiny bloodsucking mites in a bid to kill them off after bedbug complaints grew by 40 percent in the past three years.

"Everyone wants to come to New York, including bedbugs," said New York City Councilwoman Christine Quinn. "But we have a message for them ... drop dead."

Former U.S. President Bill Clinton has battled an outbreak at his Harlem office, along with lingerie outlet Victoria's Secret, teen clothing store Hollister and countless hotels who have lost thousands of dollars in revenue fighting the bedbug.

Wireless sensor watches blood sugar for diabetics

By Maggie Fox

WASHINGTON (Reuters) - Researchers have developed an implantable sensor that measures blood sugar continuously and transmits the information without wires -- a milestone, they said, in diabetes treatment.

 The device worked in one pig for more than a year and in another for nearly 10 months with no trouble, they reported in the journal Science Translational Medicine.

It takes the diabetes field a step closer to development of an "artificial pancreas" -- a device that can replace natural functions to control how the body handles blood sugar.

Japanese women extend life expectancy to new high

DateMonday, July 26, 2010 at 06:01PM

TOKYO – Japanese women are expected to live almost 86 1/2 years, topping the world longevity ratings for the 25th straight year, the government reported Monday.

The statistics for 2009 compiled and published by the Ministry of Health, Labor and Welfare showed both Japanese women and men extended their average life expectancy to new records — 86.44 years for women and 79.59 years for men. Average life spans rose by almost five months for women and nearly four months for men compared to the previous year.

Japanese men, however, saw their average life expectancy slip to fifth from fourth in the world ranking, according to a ministry official, who spoke on condition of anonymity, citing department rules.

Urge Kids to Drink Water During Hot Weather: Expert

DateFriday, July 23, 2010 at 03:18PM

FRIDAY, July 23 (HealthDay News) -- This summer's exceptionally hot weather means children are at increased risk for dehydration, a pediatric expert warns.

"It's always important to keep your kids hydrated, but when you're dealing with this kind of heat it can be especially dangerous," Dr. Sean Cahill, an associate professor in the pediatrics department at Loyola University Chicago Stritch School of Medicine, said in a Loyola news release.

"Dehydration puts kids at risk for heat-related illnesses like heat stroke. They can suffer from rhabdomyolysis, which is when their muscles break down and this process leads to kidney failure and damaged muscle cells from crystals in the urine," Cahill noted.

Circumcision of little use in preventing HIV/AIDS among US gays

DateFriday, July 23, 2010 at 02:44PM

Offering circumcision would have a very small effect on reducing HIV transmission rates among gay and bisexual men in the United States, according to researchers presenting findings at the XVIII International AIDS Conference held this week in Vienna, Austria.

Three key studies in Africa in 2005 and 2007 showed that HIV transmission rates were decreased in men who were circumcised. These clinical trials were conducted on heterosexual males in Uganda, Kenya and areas of sub-Saharan South Africa. All three random trials showed that circumcision reduced the risk of female-to-male HIV transmission by 50 to 60 percent.

The success of these trials offered hope that similar trials for homosexual men in the U.S. would reveal similar results.

'Cut down on meat to lose weight'

DateThursday, July 22, 2010 at 12:09PM

Eating less meat may be the key to keeping a healthy weight, say researchers.

A European study of almost 400,000 adults found that eating meat was linked with weight gain, even in people taking in the same number of calories.

The strongest association was found with processed meat, such as sausages and ham, the Imperial College London team reported.

It suggests that high-protein diets may not help slimmers in the long run.

New research could lead to better treatment for celiac disease

Experts identify three culprits for gluten allergy


HONG KONG (Reuters) - Researchers have identified three fragments in gluten that appear to trigger a disorder in people who are allergic to the wheat protein.

The findings, published on Thursday in the journal Science Translational Medicine, may lead to a more targeted cure instead of what sufferers practice now -- life-long abstinence from food containing gluten, such as cereal, pasta, cookies and beer.

"If you can (narrow down) the toxicity of an allergen to a few components, that enables you to make a highly targeted therapy in a way that you no longer need to target the whole immune system," said researcher Robert Anderson of The Walter and Eliza Hall Institute of Medical Research in Victoria, Australia.

New formula can predict whether fertility treatment will succeed

Test can predict success of IVF: U.S. report

WASHINGTON (Reuters) - U.S. researchers have developed a formula that can predict whether fertility treatment will succeed more accurately than using age alone, and used it to develop a commercial test.

They said their test, published in the Proceedings of the National Academy of Sciences on Monday, could save couples the agony and expense of multiple attempts to have babies using in vitro fertilization, also known as IVF.

Surprisingly, they said, the test showed that couples who would have been discouraged from trying again using traditional assessments were actually likely to succeed.

In IVF, egg and sperm are united in a lab dish and resulting embryos are implanted into the mother's uterus to grow. Predicting whether it will work is tricky and doctors rely heavily on a woman's age.

WHO encouraged that more people receiving AIDS treatment

Early treatment key for HIV-positive patients: WHO


By Kate Keiland

VIENNA (Reuters) - The number of people receiving medicines for the AIDS virus leapt by a quarter last year but more patients need to be brought into treatment before they are too sick, the World Health Organisation said on Monday.

Presenting the data at an international conference on AIDS in Vienna, the WHO said an estimated 5.2 million people were being treated for the AIDS virus at the end of 2009 after an extra 1.2 million people started treatment during the year.

It described the increase -- the largest in a single year -- an "an extremely encouraging development" but called for more programs to help patients receive treatment before the virus starts to make them very sick.

"Starting treatment earlier gives us an opportunity to enable people living with HIV to stay healthier and live longer," said Gottfried Hirnschall, WHO director of HIV/AIDS.

An estimated 33.4 million people now live with HIV/AIDS around the world. The United Nations says 15 million people need AIDS drugs, so the latest increase means that only just over a third are getting them.

Avastin fails to slow breast cancer: FDA

DateFriday, July 16, 2010 at 05:38PM

Federal health scientists said Friday that followup studies of a Roche breast cancer drug show it failed to slow tumour growth or extend patient lives, opening the door for a potential withdrawal in that indication.

The U.S. Food and Drug Administration (FDA) approved Roche's blockbuster Avastin in 2008 based on early-stage trials showing it shrank tumours caused by breast cancer. The decision was controversial because drugs for cancer patients who have never been treated before must usually show evidence they extend lives.

Avastin's so-called "accelerated approval" was based on the condition that later studies would show a survival benefit.

But in briefing documents posted online, FDA reviewers said two followup studies recently submitted by Roche failed to show that Avastin significantly extended lives compared to chemotherapy alone.

Additionally, the FDA said more recent data did not confirm the tumour shrinkage seen in earlier studies. Patients taking Avastin showed significantly more side-effects, including high blood pressure, fatigue and abnormal white blood cell levels.

Fibromyalgia sufferers ten times more likely to commit suicide than general population: study

DateFriday, July 16, 2010 at 11:58AM

By Genevra Pitman

NEW YORK (Reuters Health) - When treating women with fibromyalgia, doctors should be on the lookout for depression and warning signs of suicide, according to a new study.
 

"People with fibromyalgia don't just have fibromyalgia," Dr. Lesley Arnold, a professor of psychiatry at the University of Cincinnati who studies fibromyalgia but was not involved with the current research, told Reuters Health.

Danish researchers looking at death rates in women diagnosed with this chronic pain condition found that the risk of death from suicide was ten times higher than in the general population. They also found a higher-than-average risk of death for liver disease and strokes, but no difference in overall death rates.

Patients with fibromyalgia - about 2 percent of the U.S. population - suffer from widespread pain and have tender points that are painful to the touch. There is no cure for fibromyalgia, and pain medications often aren't very helpful, so patients can have pain that is bad enough to disrupt their everyday lives for years.

People with fibromyalgia also have higher rates of psychiatric illness than the general population, and about 90 percent of those with the condition are women.

Canadian firm fined $5.5M for deceptive claims

DateThursday, July 15, 2010 at 10:05AM

Iovate Health Sciences charged and fined in United States

A Canadian supplement company has been fined $5.5 million in the U.S. for falsely advertising that its products would help consumers lose weight and treat or prevent colds and other illnesses.

Iovate Health Sciences of Oakville, Ont., falsely claimed that Cold MD and Germ MD prevented colds and flu, while Allergy MD prevented allergies and hay fever.

An ad for Accelis, a weight-loss drug, which was found to be false and misleading.

The company also claimed its products Accelis and nanoSLIM caused weight loss, and that its products were clinically proven.

The U.S. Federal Trade Commission says the ads were false and unsubstantiated.

Iovate advertised its supplements using television ads, internet websites and placed print ads in national magazines.

France votes to criminalize wearing burqa or niqab in public

DateTuesday, July 13, 2010 at 02:25PM

French lawmakers vote to ban burqa in public

By Victoria Bryan

PARIS (Reuters) - Muslim women could be fined for wearing full-length veils in public in France under a bill approved overwhelmingly Tuesday by the lower house of parliament.

The legislation, which still has to be vetted by the Constitutional Council, France's highest constitutional authority, and approved by the Senate in September, could make France the second European country to criminalize wearing the burqa or niqab.

France is home to Western Europe's largest Muslim minority, with about 5 million Muslims, but it is thought that only about 2,000 women wear the full-length veil.

The bill, which critics say stigmatizes immigrants, bans people "from wearing, in a public place, garments designed to cover the face."

Offenders would be fined 150 euros ($189) or required to take part in a citizenship class.

Vitamin D guidelines raised by bone health group

DateMonday, July 12, 2010 at 02:00PM

Canadian adults can take more vitamin D supplements than recommended under previous guidelines, Osteoporosis Canada says.

Current Canadian recommendations for vitamin D intake are more than 10 years old and are based on preventing rickets, not properly conducted dosing studies, researchers said in Monday's issue of the Canadian Medical Association Journal.

The new guidelines recommend daily supplements of:

  • 400 to 1,000 IU for adults under age 50 without osteoporosis or conditions affecting vitamin D absorption.
  • 800 to 2,000 IU for adults over 50.

"A daily supplement of 25 mg (800 IU) should now be regarded as a minimum dose for adults with osteoporosis," wrote Dr. David Hanley of the University of Calgary Health Sciences Centre and his colleagues.

Screening Guidelines Miss Many Kids With High Cholesterol

DateMonday, July 12, 2010 at 11:02AM

By Serena Gordon

MONDAY, July 12 (HealthDay News) -- Although elevated cholesterol levels are generally considered an adult problem, a new study suggests that current screening guidelines for cholesterol in children miss many kids who already have higher cholesterol levels than they should.

The study found that almost 10 percent of children who didn't fit the current criteria for cholesterol screening already had elevated cholesterol levels.

"Our data retrospectively looked at a little over 20,000 fifth-grade children screened over several years. We found 548 children -- who didn't merit screening under current guidelines -- with cholesterol abnormalities. And of those, 98 had sufficiently elevated levels that one would consider the use of cholesterol-lowering medications," said Dr. William Neal, director of the Coronary Artery Risk Detection in Appalachian Communities (CARDIAC) Project at the Robert C. Byrd Health Science Center at West Virginia University.

When dieting, watch your vitamins: study

DateFriday, July 9, 2010 at 05:10PM

By Lynne Peeples

(Reuters Health) - When weighing the benefits of one weight-loss plan over another, dieters may want to consider what else might be cut with the calories and carbs, suggests a new study.

More than $30 billion a year is spent on weight loss products in the U.S., with one in three adults reportedly trying to trim pounds.

The focus of these popular diets typically rests on both the overall amount of food consumed and the relative quantities of proteins, fats and carbohydrates. Vitamins and minerals tend to be overlooked.

In a comparison of four weight-loss plans, researchers from Stanford University in California found significant differences in the consumption of these nutrients.

"Shifting around the food sources that are good sources of fats versus carbohydrates means more than just changing fat and carbohydrate levels," lead researcher Christopher Gardner told Reuters Health in an email.

Antibody finding may help in quest for AIDS vaccine

DateFriday, July 9, 2010 at 01:29PM

By Maggie Fox

WASHINGTON (Reuters) - Researchers have discovered antibodies that can protect against a wide range of AIDS viruses and said they may be able to use them to design a vaccine against the fatal and incurable virus.

The bodies of some people make these immune system proteins after they are infected with the AIDS virus, when it is too late for them to do much good. But a properly designed vaccine might help the body make them much sooner, the researchers reported in Friday's issue of the journal Science.

"I am more optimistic about an AIDS vaccine at this point in time than I have been probably in the last 10 years," Dr. Gary Nabel of the National Institute of Allergy and Infectious Diseases, who led the study, said in a telephone interview.

Pfizer gets EU approval for kids' cholesterol drug

DateTuesday, July 6, 2010 at 02:55PM

By LINDA A. JOHNSON

TRENTON, N.J. – The European Union has approved a new chewable form of cholesterol blockbuster Lipitor for children 10 and up with high levels of bad cholesterol and triglycerides, a type of blood fat, Pfizer said Tuesday.

The approval includes children whose high blood fats are due to an inherited disease that causes extremely high cholesterol levels, familial hypercholesterolemia.

New York-based Pfizer Inc. won U.S. approval for Lipitor use in children 10 to 17 with that condition in 2002.

Lipitor is the world's top-selling drug, with 2009 sales of about $13 billion, but its U.S. patent expires at the end of November 2011. Pfizer, the world's biggest drugmaker, will quickly lose most Lipitor revenue once generic competition hits, so the company has been trying to boost sales where possible before then.

10,000-plus in U.S. die for lack of cancer screens: CDC

DateTuesday, July 6, 2010 at 02:32PM

By Maggie Fox

WASHINGTON (Reuters) - At least 10,000 people and possibly far more die in the United States each year because they have not been screened for colon or breast cancer, according to a government report released on Tuesday.

But more people are being screened than ever before, the U.S. Centers for Disease Control and Prevention said in the first of a series of new reports on health statistics.

"We are encouraged by a significant increase in colon cancer screening rates over recent years," CDC Director Dr. Thomas Frieden told reporters in a telephone briefing.

But, he added, "more than a third of Americans who need to be screened haven't been screened."

Heart disease patients with anxiety 'at greater risk'

DateMonday, July 5, 2010 at 05:17PM

Heart disease patients may be at higher risk of heart attacks, strokes, heart failure and death if they suffer from anxiety too, a US journal report says.

In a study of more than 1,000 people with heart disease, researchers noted a 74% increased risk of cardiovascular events in those with an anxiety disorder.

The study appeared in Archives of General Psychiatry.

More research is needed to understand the link, say British experts.

Researchers from Tilburg University in the Netherlands followed up the group of patients after an average of five and a half years.

They found that the yearly rate of cardiovascular events was 9.6% in the 106 patients who suffered from a general anxiety disorder.
