Herbal remedy may improve arthritis symptoms

A traditional herbal remedy may treat rheumatoid arthritis as effectively as an FDA-approved drug treatment, according to a preliminary study published this week in the Annals of the Rheumatic Diseases.

Triptergium wilfordii Hook F, also known as the "Thunder God Vine," has long been used in traditional Chinese medicine to treat joint pain and inflammation, though no U.S. manufacturer currently sells the root extract, according to the NIH.

"It actually does show a clinical benefit," said Dr. Eric Matteson, rheumatology chair at Mayo Clinic, who was not involved with the study. "I think it is something that deserves further evaluation, without a doubt."

Colon cancer rates down since 1980s

Colon cancer rates down since 1980s

Colon cancer, which was once the most common cause of cancer death in America, has been on a steady decline for decades, according to a new study in CA: A Cancer Journal for Clinicians.

In 1985, there were an estimated 66.3 cases of colon cancer for every 100,000 adults in the United States. By 2010 that rate had fallen to 40.6 cases for every 100,000 adults. Deaths dropped during the same time period as well - from 28.5 to 15.5 deaths per 100,000 people.

"Incidence is declining primarily because of screening and finding polyps, which are precancerous lesions that can be removed," said Dr. Otis Brawley, chief medical officer for the American Cancer Society. "We find these precancerous lesions, remove them and 'voilà!' the patient doesn't get cancer."

Middle-aged? Put down the meat

Eating a high-protein diet in middle age could increase your risk of diabetes and cancer, according to a study published this week in the journal Cell Metabolism. But don't stay away from meat for too long - the same study showed those over 65 need more protein to reduce their mortality risk.

Background

Insulin-like growth factor 1, or IGF-1, is a protein in your body related to growth and development. Past studies have linked IGF-1 to age-related diseases, including cancer. Mice and humans with higher levels of IGF-1 often have a higher risk of developing these diseases.

Scientists believe protein intake plays a role in IGF-1 activity. Eating less protein, studies have shown, can lead to lower levels of IGF-1 in your body. So theoretically, protein consumption could be directly linked to disease incidence and death. FULL POST


Schoolchildren are eating more fruits, veggies

Schoolchildren are eating more fruits, veggies

Are schoolchildren actually eating more fruits and vegetables under the new school lunch program? Apparently they are, according to a new study published Tuesday in the American Journal of Preventive Medicine.

Children returning to school beginning in fall 2012 found some significant changes to their cafeteria menus: more fruits, vegetables, and whole grains. The healthier foods were the result of changes to the National School Lunch Program made under the Healthy, Hunger-Free Kids Act of 2010.

But lack of enthusiasm about these new requirements soon surfaced. A few school districts even dropped out of the lunch program.

However, the authors of this study say their research proves the opposite: “Contrary to media reports, these results suggest that the new school meal standards have improved students' overall diet quality. Legislation to weaken the standards is not warranted.” FULL POST

Study: Children of older fathers face higher risk of psychiatric disorders

Do men have a biological clock of sorts? A large new study suggests they may.

Compared to younger fathers, older fathers' children were found to be significantly more at risk for a host of psychiatric disorders, according to the study, published Wednesday in the journal JAMA Psychiatry.

For example, the children of fathers ages 45 and over were three times more likely to have an autism spectrum disorder, 13 times more likely to have ADHD, and 24 times more likely to have bipolar disorder than the children of fathers aged 20 to 24.

For the study, researchers analyzed data from 2.6 million children born in Sweden between 1973 and 2001, making it one of the largest and most comprehensive studies on the effects of paternal age.

Donating kidney may raise disease risk slightly

Those who make life-saving kidney donations may face a slightly increased risk of suffering from end-stage renal disease themselves, according to a study published Tuesday in the Journal of the American Medical Association (JAMA).

The study authors compared living kidney donors to healthy individuals who would also likely qualify to donate but never did. While the actual donors had an estimated lifetime risk of 90 out of 10,000 for end-stage renal disease (ESRD), the nondonors’ risk was slightly lower at 14 out of 10,000.

“As a medical community, we feel that it’s our imperative to understand, as well as we possibly can, what these risks are and communicate them with people,” says study author Dr. Dorry Segev, a professor of surgery at John Hopkins University School of Medicine.

Banned pesticides linked to endometriosis

Banned pesticides linked to endometriosis

Women with higher levels of pesticides in their blood are also more likely to have endometriosis, according to a new study published Tuesday in the journal Environmental Health Perspectives.

Endometriosis is a chronic condition in which tissue normally lining the uterus’ interior walls also grows outside the uterus, commonly to the ovaries, fallopian tubes, or pelvis –- causing pelvic pain and infertility.

“It affects women during their reproductive years and it could be that as many as 10% of women during reproductive ages have endometriosis,” says Victoria Holt, a researcher at the Fred Hutchinson Cancer Research Center, a professor of epidemiology at the University of Washington and lead study author.

More than 5 million women have endometriosis, according to the U.S. Department of Health and Human Services' Office of Women's Health.

“What we know about endometriosis is that it's an estrogen-driven disease. Women who have more estrogen are more likely to have it," Holt says.

Once in the body, some organochlorine pesticides (OCPs) are believed to mimic estrogen, possibly contributing to endometriosis. FULL POST


Youths, violence and gun ownership

Youths, violence and gun ownership

Nearly one in four young adults and teenagers admitted to a Flint, Michigan, emergency department for non-sexual assault injuries say they currently possess a firearm of their own or have possessed one within the past six months, according to a new study published Monday in the journal Pediatrics.

The estimate is higher than past studies have found. One reason, according to the researchers, is that the young people studied had been involved in violent disputes; previous research looked at all comers to the emergency room.

Only 17% of those reporting they possessed a firearm say they obtained the weapon legally. FULL POST


IVF may slightly increase mental retardation risk

IVF may slightly increase mental retardation risk

While new research finds no significant link between autism and singleton children conceived via in vitro fertilization (IVF), a slightly increased risk of mental retardation, or intellectual disability, was found following IVF treatment including intracytoplasmic sperm injection (ICSI).

ICSI involves the injection of a single sperm into an egg to fertilize it.  Researchers found when ICSI was used to overcome male infertility, the  risk for intellectual disability increased slightly compared to IVF without ICSI.

"The reasons (for an increased risk) could be the underlying infertility,” says Abraham Reichenberg, one of the study authors and a professor at Mt. Sinai School of Medicine in New York and King's College London.

“It could be something happening in the many steps that are involved in each of the treatments, or something that's happening later in the pregnancies, or all of them combined together.  It could be any one of those steps.  In any one of them it could go wrong." FULL POST


Report: New bird flu deadlier than swine flu

Report: New bird flu deadlier than swine flu

The H7N9 bird flu virus, first identified in humans earlier this year, kills about 36% of infected people admitted to hospitals in China, according to a new report published Sunday in the British medical journal The Lancet.

Far more difficult to estimate, according to the study, is how many die in the general population after becoming infected, as the most severe cases are also more likely to lead to hospitalization.

That estimate – a 0.16% to 2.8% overall fatality rate for those showing symptoms of infection – suggests that the H7N9 virus is less deadly than the H5N1 Bird Flu first appearing in 2003, and more deadly than the 2009 H1N1 swine flu pandemic. FULL POST
