Some herbal remedies may increase the potency of prescription drugs for heart disease or make them less effective, a team of experts concluded.
Mixing herbs and drugs also could cause serious heart rhythm problems and bleeding, according to the review published in the Journal of the American College of Cardiology.
Use of herbal supplements among elderly patients is especially concerning because they typically have more than one disease, take multiple medications and already are at greater risk of bleeding, the report said.
Previous studies have sounded alarms about use of herbal supplements which are not regulated like traditional medicines. This review examined how supplements and cardiovascular drugs may interact.
"We can see the effect of some of these herb-drug interactions -- some of which can be life-threatening -- on tests for blood clotting, liver enzymes and, with some medications, on electrocardiogram," Dr. Arshad Jahangir of the Mayo Clinic in Arizona said in a telephone interview.
Many patients fail to disclose their use of herbal remedies so healthcare providers should be more probing, Jahangir said in a telephone interview.
"We need to be actively ask about alternative or complementary medicine patients may be seeking on their own to assess these potential interactions or side affects," said Jahangir, a cardiologist.
"They don't even consider that herbs could have a negative effect," he said. "Their impression is that 'natural' is safe,"
Jahangir said doctors and patients need to know about the potential harm herbal products can have, citing reports that more than 15 million Americans use herbal remedies.
The Council for Responsible Nutrition, an industry trade association, said the article represents a biased, poorly written and contrived attack on herbal supplements.
"Many herbal supplements offer healthful benefits and fiber, garlic, and Hawthorne provide heart health benefits, and the potential risk for a drug interaction can be eliminated by speaking openly with your doctor," the group's vice president, Douglas MacKay, said in a statement.
"If consumers are buying from reputable companies, they can feel confident in the quality and safety of these products," MacKay added.
Ginkgo biloba is taken to sharpen cognitive skills and St. John's wort is used to fight depression and sleep disorders.
The Nutritional Business Journal, an industry publication, estimates U.S. consumer sales of supplements climbed more than 6 percent in 2008 to reach $25.2 billion.
C-Section Doesn't Affect Breast-Feeding: Study
Contrary to a widely held belief, having a "non-natural" instrumental or Caesarean section birth doesn't affect how long a mother breast-feeds, says a British study that included 2,000 new moms.
But the researchers did find that a mother's ethnicity and the number of previous births did have an impact. White mothers were 70 percent more likely to stop breast-feeding than non-white women, BBC News reported.
The study also found that babies who began breast-feeding within an hour of being born weren't breast-fed longer than those who started breast-feeding within 48 hours of birth.
All the mothers in the study received breast-feeding help from the same peer support group. On average, the moms breast-fed for 21 weeks, and half of them breast-fed for more than 27 weeks, much longer than the national average, BBC News reported.
The study was published in the journal BMC Pediatrics.

Antibiotics Combo More Effective Than Single Drug
Having patients take the two antibiotics lankacidin and lankamycin at the same time is a more effective way to combat pathogenic bacteria than using either antibiotic on its own, says a new study.
Individually, each drug is marginally effective at fighting pathogens, said the American and Israeli researchers. However, when used together, the two antibiotics are much more likely to be effective against dangerous pathogens such as methicillin-resistant Staphylococcus aureas (MRSA), United Press Internationalreported.
"What we found most amazing is that the two antibiotics appeared to help each other in stopping pathogens from making new proteins and in inhibiting bacterial growth," lead investigator Alexander Mankin, professor and associate director of the Center for Pharmaceutical Biotechnology at the University of Illinois in Chicago, said in a news release.
The study appears online in the journal Proceedings of the National Academy of Sciences.

New Disinfectant Kills Wide Range Of Pathogens
A new rapid-acting disinfectant may help reduce deadly infections in hospitals, say German scientists.
The disinfectant is a simple alkaline detergent formulation mixed with 20 percent propanol, United Press International reported.
In tests on surgical instruments, the disinfectant killed bacteria, viruses, fungi and prions that cause mad cow disease in cattle and Creutzfeldt-Jakob disease in humans.
"Standard formulations that eliminate prions are very corrosive," study leader Dr. Michael Beekes of the Robert Koch Institute in Berlin, said in a news release, UPIreported. "The solution we've come up with is not only safer and more material-friendly but easy to prepare, cheap and highly effective."
The study is published in the February issue of the Journal of General Virology.

Children's Pendants Recalled Because of Cadmium
High levels of the toxic heavy metal cadmium have prompted a recall of "The Princess and The Frog" movie-themed children's pendants, the U.S. Consumer Product Safety Commission announced Friday.
Cadmium is known to cause cancer and recent research suggests it can harm brain development in children.
The voluntary recall by FAF Inc. of Greenville, R.I., includes 55,000 pendants sold exclusively at Wal-Mart stores. It's the first time a consumer product has been recalled in the United States because of cadmium, the Associated Press reported.
Several weeks ago, the AP published results of an investigation that found high levels of cadmium in "The Princess and The Frog" pendants and other Chinese-made children's metal jewelry.

Cell Phone Bans May Not Reduce Crashes
Bans on the use of cell phones and other hand-held devices while driving haven't reduced road crashes in California, Connecticut, New York or Washington, D.C., according to a new study by the Highway Loss Data Institute.
Researchers compared insurance claims in those areas and in regions that don't have cell phone bans, CNN reported. The study found no changes in collision rates before and after cell phone restrictions took effect.
"The laws aren't reducing crashes, even though we know that such laws have reduced hand-held phone use, and several studies have established that phoning while driving increases crash risk," said institute president Adrian Lund.
"So the new findings don't match what we already know about the risk of phoning and texting while driving," he added, CNN reported.

Newer Emergency Contraceptive Beats Plan B in Study
A newer type of morning-after pill called ulipristal acetate (brand name ellaOne) is more effective than levonorgestrel (brand name Plan B), the most widely used emergency contraceptive, says a new study that included 1,700 women, ages 16 to 36.
The women received either Plan B or ellaOne within three to five days of having unprotected sex. There were 22 pregnancies in the Plan B group and 15 pregnancies in the ellaOne group, the Associated Press reported.
The researchers also found that the risk of pregnancy among women who took ellaOne within five days after sex was nearly half that of those who took Plan B -- 1.8 percent vs. 2.6 percent. Plan B is effective only if taken within three days after sex, while ellaOne is effective for up to five days after sex.
The study -- funded by ellaOne's maker, HRA Pharma -- was published Friday in The Lancet.
Plan B is approved in more than 140 countries and is available without a prescription in nearly 50 of those countries. EllaOne is approved only in Europe and requires a prescription, the AP reported.

Students Benefit From Milk Switch: Study
Substituting low-fat and fat-free milk for whole milk in schools can greatly reduce students' consumption of calories and fat and help combat childhood obesity, says a new study.
It examined the impact of the New York City Department of Education's decision to switch from whole fat to low-fat/fat-free milk in 2005. The change meant that a milk-drinking student was exposed to 33 fewer calories and 3.4 fewer grams of fat per school day, which works out to nearly 6,000 fewer calories and more than 600 fewer grams of fat a year.
The effect was even greater for a student who drinks white milk -- 7,000 fewer calories and more than 900 fewer grams of fat a year. The researchers also found that school purchases of milk increased 1.3 percent after the switch.
Making changes to school milk policy can help reduce students' consumption of calories and fat without decreasing their intake of important vitamins and minerals, the researchers concluded.
The study appears in the latest Morbidity and Mortality Weekly Report, published by the U.S. Centers for Disease Control and Prevention.

Rural Hospitals Admit More Medicare Patients
In 2007, Medicare patients accounted for 45 percent of all stays at rural hospitals and 35 percent of stays at urban hospitals, says a new U.S. government report.
The latest News and Numbers from the Agency for Healthcare Research and Quality also found that 36 percent of urban hospital patients and 25 percent of rural hospital patients were covered by private insurance. About 20 percent of patients in both urban and rural hospitals had Medicaid and about 5 percent were uninsured.

States Weigh Tougher Rules on Youth Head Injuries
Measures to tighten restrictions on when young athletes can return to play after suffering a head injury are being considered by a number of states.
Last year, Washington state set a precedent when it passed what's considered the strongest return-to-play law in the nation. It forbids athletes under 18 from returning to the game unless they have written approval from a licensed health-care provider. Similar bills are pending in several other states, including California and Pennsylvania, the Associated Press reported.
Last year, Maine lawmakers approved creation of a working group on the prevention, diagnosis and treatment of concussions in young athletes. New Jersey has created a commission to examine brain injury research.
On Monday, a U.S. House committee will hold a forum to look at how high schools and colleges handle athlete concussions, the AP reported. The same committee has held hearings on head injuries in the NFL.

Vital Social Skill Seems to Develop at Young Age
Babies develop an important social skill -- gazing -- when they're as young as 5 months old, according to a British study.
The researchers found that when babies pay joint attention to an object, they use an area of the brain (left prefrontal cortex) that's involved in complex cognitive and social behaviors, United Press International reported.
Joint attention -- when two people share attention to the same object -- is an important social skill necessary for teaching, language learning and collaboration, the researchers explained. Impairment in joint attention is one of the earliest signs of autism.
The study appears in the journal Biology Letters.

Curbs on L.A. Medical Marijuana Dispensaries Called 'Disaster' for Patients
A Los Angeles ordinance that places restrictions on medical marijuana dispensaries will dramatically restrict patient access to the drug, according to critics of the law.
The measure, passed Tuesday by the city council, forces dispensaries to comply with local restrictions, such as being at least 1,000 feet away from parks, schools and libraries. In addition, dispensaries will not be allowed to abut or be across an alley from residential property, the Los Angeles Times reported.
The restrictions will make it difficult to find suitable locations, say the operators of the estimated 150 medical marijuana dispensaries.
"It's a disaster for patients," James Shaw, director of the Union of Medical Marijuana Patients, told the city council after the vote, the Times reported.

Defect Prompts Recall of 2 Million Needles
Two million Exel/Exelint Huber needles are being recalled because there's a risk they can push pieces of silicone into patients' bodies, says the U.S. Food and Drug Administration.
The needles are used to access injection ports implanted beneath the skin of patients with chronic diseases who require frequent injections, the Associated Press reported.
The voluntary recall by Miami-based Nipro Medical Corp. includes needles made between January 2007 and August 2009.
An FDA inspection of Nipro's manufacturing plant found that 60 to 72 percent of the needles have a design problem that can cause the needle to dislodge bits of silicone from the injection ports and possibly push the pieces into a patient's bloodstream, the AP reported.

Victoza Approved for Type 2 Diabetes
Victoza (liraglutide) has been approved to treat type 2 diabetes in some adults, the U.S. Food and Drug Administration said in a news release.
But the agency warned that the once-daily injection shouldn't be used as an initial (first-line) treatment until additional studies are completed, since the drug may cause thyroid tumors or a rare disease called medullary thyroid cancer. People at risk for this type of cancer shouldn't use the drug, the FDA stressed.
Victoza, among a class of medicines called glucagon-like peptide-1 (GLP-1) receptor agonists, is meant to be used along with diet and exercise to control blood sugar by helping the pancreas make more insulin after a person eats.
In clinical studies involving more than 3,900 patients, people who took Victoza had more cases of pancreatic inflammation (pancreatitis) than people who took other diabetes drugs, the FDA said. The drug should be stopped if severe abdominal pain develops or tests confirm pancreatitis, the agency said.
Victoza is produced by Denmark-based Novo Nordisk.

Hearing Problems Decreasing: Study
The rate of hearing problems among Americans ages 45 to 75 has been decreasing for years, says a new study.
Researchers analyzed the results of hearing tests conducted between 1993 and 2008 on about 5,300 people who were at least 45 years old and born between 1902 and 1962, the Associated Press reported. The participants were residents of Beaver Dam, Wis., and their children, who lived in different places.
Men had an average 13 percent reduced risk of hearing impairment for every five-year increase in their date of birth, the study found. For women, the decrease was about 6 percent, the AP reported.
The study was published in the American Journal of Epidemiology.
Experts suggested a number of reasons for the decline in hearing problems, including fewer noisy jobs, better workplace ear protection, immunizations and antibiotics that prevent certain diseases, and perhaps even a decrease in smoking, the AP reported.

Processed Foods Main Source of Sodium for Many
Many people consume too much sodium, and processed foods are the main reason why, new research shows.
ScienceDaily reported Tuesday on the study set to appear in the February issue of the American Journal of Clinical Nutrition. Australian researchers conducted a systematic review of the sodium contents of processed foods available in that country. Previous research has shown that high sodium intake can raise blood pressure.
The team at the George Institute for International Health in Sydney said their database and descriptive data offer the tools and information needed for continued monitoring of sodium content in processed foods.
The Australian research "is important in that these real-time data provide baseline information on the sodium content of many foods in Australia," American Society for Nutrition spokesman Roger Clemens said in a society news release. "A successful sodium-reduction process is likely to involve several steps, a gradual decrease in sodium such that food safety is not compromised while attempting to reduce the risk of elevated blood pressure among those who may respond to lower dietary sodium."

More Melamine-Tainted Dairy Products Found in China
Chinese officials say they've ordered the removal of melamine-tainted dairy products from the shelves of more than a dozen convenience stores in the southern province of Guizhou.
The order to remove cartons of milk and frozen milk products dating from early 2009 came after health inspectors tested the products and found they contained melamine, the Associated Press reported.
Health authorities are investigating why the tainted dairy products hadn't already been pulled from the convenience store shelves, said Guizhou government spokeswoman Ling Hu.
The action comes more than a year after melamine-contaminated milk sickened hundreds of thousands of children in China, the AP reported. Melamine is used in the manufacture of plastics and fertilizer.

U.S. Unprepared for Bioterror Attack: Panel
The United States isn't prepared for a biological terrorist attack, such as the release of deadly bacteria or viruses, according to a Congressionally mandated panel.
The poor preparation for the swine flu outbreak in 2009 shows that the nation isn't positioned to respond to something more serious, said Randy Larsen, executive director of the Commission on the Prevention of Weapons of Mass Destruction Proliferation, the Associated Press reported.
Larsen noted that the United States ran out of H1N1 swine flu vaccine despite a six-month warning from health officials that the disease would be potentially deadly.
He said no one in the Obama administration has the lead for protecting the nation against a bioterrorism attack, the AP reported.

Blood Glucose Level Affects Decision Making: Study
Blood glucose levels affect a person's decisions about present and future rewards, says a new study.
Participants were asked a series of questions about whether they'd prefer to receive a certain sum of money tomorrow or a larger amount at a later date. The questions were asked before and after drinking either a regular soda or a diet soda with an artificial sweetener, United Press International reported.
Those who drank a regular soda and had a higher blood glucose level were more likely to decide to receive a larger amount of money at a later date, while those who drank a diet soda and had a lower blood glucose level tended to take the smaller amount of money immediately.
The University of South Dakota researchers said their findings suggest that higher levels of blood glucose are associated with more future-oriented decisions, UPIreported.
The study appears in the journal Psychological Science.

U.S. Veterans With PTSD Fight for Better Coverage
Thousands of U.S. veterans of the Iraq and Afghanistan wars who were discharged from the military because of post-traumatic stress disorder (PTSD) have been told they can apply for an expedited review of their cases to determine if they were improperly denied benefits.
The legal notices sent to about 4,300 veterans explain that they have until July 24 to join a lawsuit against the U.S. military in order to be included in the expedited review, the Associated Press reported.
The lawsuit was launched by seven combat veterans who allege the military illegally denied health care and other benefits to veterans discharged because of PTSD during a six-year period that ended Oct. 14, 2008.
Each of the seven plaintiffs was given a disability rating of 10 percent or less when discharged. Since October 2008, the military has given a disability rating of at least 50 percent to those discharged with PTSD, the AP reported.
A higher disability rating ensures lifelong monthly disability benefits for a veteran, free health care for the veteran and his/her spouse and health care for the veteran's minor children.

Regular Sex Benefits Men's Hearts: Study
Having sex at least twice a week can reduce a man's risk of serious heart disease by almost half, says a new study.
It included more than 1,000 men, aged 40 to 70, who had no history of heart disease and were followed for 16 years. Men who had sex twice a week were as much as 45 percent less likely to develop serious heart conditions than men who had sex less than once a month, CBS News reported.
The study appears in the American Journal of Cardiology. Women weren't part of the study, but experts believe the findings would be true for them too.
Sex could help heart health through its physical and emotional effects, said the researchers, CBS News reported. Sex can be good exercise and men who have regular sex are more likely to be in a healthy relationship that reduces stress and provides them with social support.

No Medical Marijuana Limits: California Supreme Court
A California law that imposed limits on the amount of medical marijuana a patient can legally possess was overturned Thursday by the California Supreme Court.
In 1996, voters approved a measure to allow patients with a doctor's recommendation to possess an unspecified amount of marijuana. But in 2003, state lawmakers limited that amount to 8 ounces of dried marijuana, theAssociated Press reported.
In its ruling, the court said only voters can alter amendments they've added to the state's constitution through the initiative process.
In related news, the Washington state Supreme Court ruled that police can arrest a patient or search a home even if a patient has a doctor's permission to use marijuana for medicinal purposes. In the ruling, the court upheld the conviction of a man who had a doctor's authorization and was arrested with 2 pounds of marijuana.

Past Decade Warmest on Record: NASA
The past decade was the warmest on record, according to Earth surface temperature data released Thursday by the U.S. National Aeronautics and Space Administration.
NASA said the figures also show that 2009 was the second warmest year since 1880, when scientists first started recording such data. The warmest year was 2005 and the other warmest years have all occurred since 1998, The New York Times reported.
Changes in ocean heating and cooling cycles cause variations in annual global temperatures, but when "we average temperature over 5 or 10 years to minimize that variability we find global warming is continuing unabated," said James E. Hansen, director of NASA's Goddard Institute for Space Studies.
The newly released data show an upward trend of about 0.36 degrees Fahrenheit (0.2 degrees Celsius) per decade over the past 30 years. Since 1880, there's been an average 1.5 degree F rise in global temperatures, the Times reported.

Same-Sex Couples Good Parents: Study
Same-sex couples are as good as male/female couples when it comes to parenting, say researchers who reviewed 81 studies of one- and two-parent families, including gay, lesbian and heterosexual couples.
"Children being raised by same-gender parents, on most all of the measures that we care about, self-esteem, school performance, social adjustment and so on, seem to be doing just fine and, in most cases, are statistically indistinguishable from kids raised by married moms and dads on these measures," said review co-author Timothy Biblarz, of the University of Southern California, USA Todayreported.
"It's more about the quality of the parenting than the gender of the parents," noted co-author Judith Stacey of New York University.
The researchers also found that "two women who choose to parent together are slightly more likely than a heterosexual couple to be actively committed to hands-on parenting. We don't have data yet on two men parenting, but I think it will come out fairly similar," Stacey said, USA Today reported.
The review findings will be published Friday in the Journal of Marriage and Family.

Too Much Sitting May Harm Health
Sitting for extended periods can harm your health, even if you get regular exercise, experts warn.
It may be time to rethink how physical activity is defined in order to emphasize the dangers of sitting, Elin Ekblom-Bak, of the Swedish School of Sport and Health Sciences, wrote in an editorial published this week in the British Journal of Sports Medicine, the Associated Press reported.
Guidelines currently recommend the minimum amount of physical activity, but don't suggest people limit the time they spend sitting.
"After four hours of sitting, the body starts to send harmful signals," said Ekblom-Bak, the AP reported. Genes that regulate the amount of glucose and fat in the body start to shut down, she explained.
