Acupuncture may relieve joint pain caused by some breast cancer treatments

Joint pain, stiffness common side effect of routine therapy
NEW YORK (March 4, 2010) – A new study, led by researchers at the Herbert Irving Comprehensive Cancer Center at NewYork-Presbyterian Hospital/Columbia University Medical Center, demonstrates that acupuncture may be an effective therapy for joint pain and stiffness in breast cancer patients who are being treated with commonly used hormonal therapies. Results were published in the Journal of Clinical Oncology.

Joint pain and stiffness are common side effects of aromatase inhibitor therapy, in which the synthesis of estrogen is blocked. The therapy, which is a common and effective treatment for early-stage, hormone-receptor-positive breast cancer in post-menopausal women, has been shown in previous research to cause some joint pain and stiffness in half of women being treated.

"Since aromatase inhibitors have become an increasingly popular treatment option for some breast cancer patients, we aimed to find a non-drug option to manage the joint issues they often create, thereby improving quality of life and reducing the likelihood that patients would discontinue this potentially life-saving treatment," said Dawn Hershman, M.D, M.S., senior author of the paper, and co-director of the breast cancer program at the Herbert Irving Comprehensive Cancer Center at NewYork-Presbyterian Hospital/Columbia University Medical Center, and an assistant professor of medicine (hematology/oncology) and epidemiology at Columbia University Medical Center.

To explore the effects of acupuncture on aromatase inhibitor-associated joint pain, the research team randomly assigned 43 women to receive either true acupuncture or sham acupuncture twice a week for six weeks. Sham acupuncture, which was used to control for a potential placebo effect, involved superficial needle insertion at body points not recognized as true acupuncture points. All participants were receiving an aromatase inhibitor for early breast cancer, and all had reported musculoskeletal pain.

Among the women treated with true acupuncture, findings demonstrated that they experienced significant improvement in joint pain and stiffness over the course of the study. Pain severity declined, and overall physical well-being improved. Additionally, 20 percent of the patients who had reported taking pain relief medications reported that they no longer needed to take these medications following acupuncture treatment. No such improvements were reported by the women who were treated with the sham acupuncture.

"This study suggests that acupuncture may help women manage the joint pain and stiffness that can accompany aromatase inhibitor treatment," said Katherine D. Crew, M.D., M.S., first author of the paper, and the Florence Irving Assistant Professor of Medicine (hematology/oncology) and Epidemiology at Columbia University Medical Center and a hematological oncologist at NewYork-Presbyterian Hospital/Columbia University Medical Center. "To our knowledge, this is the first randomized, placebo-controlled trial establishing that acupuncture may be an effective method to relieve joint problems caused by these medications. However, results still need to be confirmed in larger, multicenter studies."

New Scolioisis Self Help Book!

Health In Your Hands - Your Plan for Natural Scoliosis Prevention and Treatment

The central premise of my book is how to diagnosis and correct scoliosis non- invasively at any stage in order to arrest it progress before it’s too late.

Scoliosis, is a widespread condition in the world. According to available statistics, the spinal disorder, that leads to an curvature of the spine, strikes nearly two to three percent of all adolescents and becomes noticeable between the age of 10 and 15, when an adolescent is very image conscious.

Nearly, one in 10 Singaporeans suffers from lumbar scoliosis, according to a recent study conducted by a team of spine surgeons led by Professor Wong Hee Kit, chairman of the Orthopedics and Hand & Reconstructive Microsurgery Cluster at the National University Health System (NUHS). Worse, the study also revealed that the condition is 1.6 times more prevalent in women and that it occurs twice more often in Chinese and Malays than in Indians.

Conventional scoliosis treatment involves braces that patients have to wear passively through the day; while surgical procedures carry significant, other risks. My book in contrast draws heavily upon my own experiences as a Chiropractor and Nutritionist, and how I have helped hundreds of scoliosis patients with nothing more elaborate than a highly customized nutritional plan and a structured exercise/stretch program that I’ve explained at length with illustrations in this book.

Among other things, the book explains in simple, layman's language the anatomy and functioning of of the human spine and its relationship to food and exercise. The book is based is painstaking research collected over years of practice with scoliosis patients of all demographics. Testimonials of some of these patients are also appended in the book.

It's my firm conviction that this book will prove a valuable informational resource to the parents, who have children afflicted with scoliosis, as well as adults who suffer from the condition.

Vaccines That Worry Parents Most

(March 1) -- A new study shows that when it comes to getting their children vaccinated, some parents have conflicted feelings. Even though one in four parents believes some vaccines can trigger autism -- a fear rooted in a controversial 1998 study that has since been retracted -- about 90 percent of them follow medical advice to have their children vaccinated.

The study, conducted by the University of Michigan and published in the journal Pediatrics, is based on a survey of 1,552 parents that was conducted last year, well before the autism-vaccine study was retracted last month. But the validity of that study had been under attack for years.

About 12 percent of parents in the Michigan study said they had refused to allow their children to receive a vaccine that a doctor recommended. The chart below shows four inoculations that those parents cited.


The vaccine for human papillomavirus protects against cervical cancer, but is fairly new. Some parents shy away from it because of their concerns about side effects. The vaccine for meningococcal diseases is also relatively new, and some people worry it causes Guillain-Barré syndrome, an immune system disorder. That link is being investigated, but federal health officials still recommend the vaccine.

The shot for measles, mumps and rubella was the subject of the now-discredited 1998 research. The parents who refused to allow their children to get the vaccine said they had heard or read negative information about it. The chickenpox vaccine also made the list, but no evidence ties it to autism, doctors have said.

The Centers for Disease Control and Prevention has information about common vaccine-safety concerns, including those involving autism.

Laryngeal Disease in Cats

Taylor SS, Harvey AM, Barr FJ et al: Laryngeal disease in cats: a retrospective study of 35 cases, J Feline Med Surg 11:954-962, 2009.

This retrospective study reviewed the medical records of 35 cats referred to the University of Bristol for investigation of laryngeal disease. Laryngeal disease is an uncommon yet important cause of dyspnea in the cat. Among the 35 cases, fourteen cats fulfilled the criteria for laryngeal paralysis (LP), 10 for neoplasia, six for inflammatory disease, and five were classified as having miscellaneous disease. The most frequently reported signs in all four groups were dyspnea, stridor and dysphonia with gagging/retching and cough occurring less frequently. Of the cats with a final diagnosis of neoplasia, four had lymphoma, four had squamous cell carcinoma, one had adenocarcinoma, and one had a poorly differentiated round cell tumor. All the cats with neoplasia were FeLV negative and three of eight cats were FIV positive. Because gross appearance of a laryngeal mass and cytology can be misleading, histopathology should always be done to make a definitive diagnosis, assist with treatment options, and offer prognostic information. In all cases of laryngeal neoplasia in this study where cervical radiography was performed, a mass lesion was noted. Thoracic radiography is also recommended in the investigation of LP in cats. Echolaryngography was found to be a useful and non-invasive tool to detect laryngeal masses and identify LP. Treatment for LP can either surgical or conservative and results can be variable, especially if the paralysis is bilateral versus unilateral. Cats with LP, laryngeal lymphoma, or laryngitis had excellent long-term survival following the appropriate treatment. [VT]

Low-fat, Mediterranean and low-carb diets 'help heart'

Three diets - Mediterranean, low-fat and low-carbohydrate - are equally effective in helping reverse blocked arteries, say Israeli researchers.

The study of 140 people, reported in the journal Circulation, found diet could reduce the fatty build up in arteries.

The Ben-Gurion University team found that by the end of the two-year study, the arterial wall had been cut by 5%.

Experts said the study was interesting, but diet was not a "magic bullet".

Atherosclerosis is a progressive condition in which the arteries thicken with fatty deposits, increasing the risk of heart attacks and strokes.

The authors of this Israeli study, which was carried out in collaboration with researchers in the US, Canada and Germany, set out to see if this natural part of ageing can be reversed through diet.

Volunteers followed one of three diets - a low-fat diet, a low-carbohydrate diet or a Mediterranean diet, which is based on eating lots of fruit and vegetables, and using olive oil as the main source of fat.

They were asked to stick to the diet for two years, and record what they ate in food diaries.

The study was carried out among overweight volunteers, mostly men, who were aged 40 to 65.

Using three-dimensional imaging, the researchers measured the volume of the wall of the carotid artery, the large artery in the neck which takes blood up to the brain. This was done at the start of the study and again after two years.

Clogged arteries

Lead researcher Iris Shai said: "It was very interesting to see that these very different diets had a similar effect.

"Some people suggest that low-carbohydrate diets are more likely to clog arteries, but we did not see that."

The research paper suggested the link could be related to falling blood pressure caused by the change in diet.

The findings were welcomed by UK experts.

Dr Charles Knight, secretary of the British Cardiovascular Society and a consultant cardiologist, said although the study was "relatively small" and was not able to follow through to find out how many people eventually had heart attacks or strokes, the results were nevertheless "very interesting".

He pointed out that the study adds weight to the growing body of research that suggests that atherosclerosis is a modifiable disease.

Ten to 15 years ago, it was thought that fatty build-up in the arteries was irreversible, but since then drugs trials have shown that it is possible for fatty deposits to be cut.

"This study shows you can do something to reduce plaque build-up, even without pills," Dr Knight said.

"It sends an effective message from a public health perspective."

However, he warned that the scale of reduction in the volume of artery walls was relatively small and that changing diet, although helpful, was "no magic bullet".

Sleep habits linked to fat gain in younger adults

Researchers found that among black and Hispanic adults younger than 40, those who typically slept for five hours or less each night had a greater accumulation of belly fat over the next five years, versus those who averaged six or seven hours.

Those who logged eight hours or more in bed each night also showed a bigger fat gain -- but it was less substantial than that seen in "short sleepers."

The study, reported in the journal Sleep, does not prove that too little or too much sleep directly leads to excess fat gain. But the findings support and extend those of other studies linking sleep duration -- particularly a lack of sleep -- to weight gain and even to higher risks of diabetes and heart disease.

The study adds to past research in part because it focused on black and Hispanic Americans -- two understudied groups who are at increased risk of obesity and its related ills, said lead researcher Dr. Kristen G. Hairston, of Wake Forest University School of Medicine in Winston-Salem, North Carolina.

It also zeroed in on the relationship between sleep and gains in abdominal fat -- both the superficial fat layers just below the skin and the "visceral" fat that surrounds the abdominal organs. Deep abdominal fat is believed to be particularly important in the risks of health conditions like diabetes, high blood pressure and heart disease, Hairston told Reuters Health.

The study included 332 African-American and 775 Hispanic-American men and women ages 18 to 81. At the outset, all reported on their sleep habits, diets, exercise levels and other lifestyle factors. The researchers used CT scans to measure participants' abdominal fat, at the start of the study and again five years later.

Among participants younger than 40, the study found, those who said they slept for five hours or less each night gained more belly fat than those who averaged six or seven hours of sleep.

On average, short sleepers showed a 32 percent gain in visceral fat, versus a 13 percent gain among those who slept six or seven hours per night, and a 22 percent increase among men and women who got at least eight hours of sleep each night.

A similar pattern was seen with superficial abdominal fat. Even when the researchers considered factors like calorie intake, exercise habits, education and smoking, sleep duration itself remained linked to abdominal-fat gain.

The findings, according to Hairston, support the belief that sleep habits affect weight, and health in general. "Sleep is an important part of your overall health -- not just in whether you're tired during the day," she said.

Individuals vary in their sleep needs, so there is no one set prescription. But "extremes of sleep," such as less than five hours per night, should raise concerns, according to Hairston. "And if you're concerned about your sleep," she said, "discuss it with your healthcare provider, just as you would discuss diet or exercise."

As for why sleep duration might affect abdominal-fat gain, there are several theories.

There may be indirect effects; people who get too little sleep may be too tired during the day to exercise, while those who spend a lot of time in bed may spend less time being active, relative to people who sleep fewer hours.

Research also suggests that sleep loss alters people's levels of appetite-regulating hormones -- which could, in theory, spur them to overeat.

Depression, which often affects people's sleep and has been linked to weight gain, could also be a factor, Hairston noted. She and her colleagues had no information on study participants' depression symptoms.

An apple a day? Study shows soluble fiber boosts immune system

URBANA – A new University of Illinois study touts the benefits of soluble fiber—found in oats, apples, and nuts, for starters—saying that it reduces the inflammation associated with obesity-related diseases and strengthens the immune system.

"Soluble fiber changes the personality of immune cells—they go from being pro-inflammatory, angry cells to anti-inflammatory, healing cells that help us recover faster from infection," said Gregory Freund, a professor in the U of I's College of Medicine and a faculty member in the College of Agriculture, Consumer and Environmental Sciences' Division of Nutritional Sciences.

This happens because soluble fiber causes increased production of an anti-inflammatory protein called interleukin-4, he said.

The study will appear in the May 2010 issue of Brain, Behavior, and Immunity and is available online at http://www.sciencedirect.com/science/journal/08891591.

In the experiment, laboratory mice consumed low-fat diets that were identical except that they contained either soluble or insoluble fiber. After six weeks on the diet, the animals had distinctly different responses when the scientists induced illness by introducing a substance (lipopolysaccharide) that causes the body to mimic a bacterial infection.

"Two hours after lipopolysaccharide injection, the mice fed soluble fiber were only half as sick as the other group, and they recovered 50 percent sooner. And the differences between the groups continued to be pronounced all the way out to 24 hours," said Christina Sherry, who also worked on the study.

"In only six weeks, these animals had profound, positive changes in their immune systems," she said.

Now Freund has a new question: Could soluble fiber offset some of the negative effects of a high-fat diet, essentially immunizing obese persons against the harmful effects of fat?

Scientists have long known that obesity is linked to inflammatory conditions, such as diabetes and heart disease.

Yet, in a recent study, the U of I scientists demonstrated that fat tissue produces hormones that appear to compensate for this inflammation. "There are significant anti-inflammatory components in fat tissue and, if they were strategically unleashed, they could potentially protect obese people from further inflammatory insults, such as a heart attack or stroke. In obese animals, you can see the body compensating in an effort to protect itself," he said.

Not all fat is bad, the researcher noted. The Mediterranean diet, which receives high marks for its health benefits, includes such foods as olive oil; salmon, tuna, sardines, and trout, which contain important omega-3 and -6 fatty acids; and plant sources of fat, such as flaxseed.

"Now we'd like to find a way to keep some of the anti-inflammatory, positive effects that develop over time with a high-fat diet while reducing that diet's negative effects, such as high blood glucose and high triglycerides. It's possible that supplementing a high-fat diet with soluble fiber could do that, even delaying the onset of diabetes," he said.

This study is one of the first to provide two valuable lessons, said Sherry. The first, already noted, is that soluble fiber has direct anti-inflammatory effects and builds up the immune system. The second is that the amount of soluble fiber necessary to achieve these health benefits is a reasonable, not a pharmacological, amount.

The recommended daily dietary recommendation is 28 to 35 grams of total fiber, but most of the FDA's health claims are for insoluble fiber, and that's where things get a bit complicated, she said.

"Not all fiber is created equal, although you wouldn't know that by reading nutrition labels," said Sherry. "Most manufacturers don't tell you how much of each type of fiber a food contains, and we think it's important that this information be included on a product's packaging."

Good sources of soluble fiber are oat bran, barley, nuts, seeds, lentils, citrus fruits, apples, strawberries, and carrots. "We used a citrus-based pectin in our study," Sherry said.

Insoluble fiber, found in whole wheat and whole-grain products, wheat bran, and green, leafy vegetables, is also valuable for providing bulk and helping food move through the digestive system, but it doesn't provide the boost to the immune system that soluble fiber provides.

Yet, in a recent study, the U of I scientists demonstrated that fat tissue produces hormones that appear to compensate for this inflammation. "There are significant anti-inflammatory components in fat tissue and, if they were strategically unleashed, they could potentially protect obese people from further inflammatory insults, such as a heart attack or stroke. In obese animals, you can see the body compensating in an effort to protect itself," he said.

Not all fat is bad, the researcher noted. The Mediterranean diet, which receives high marks for its health benefits, includes such foods as olive oil; salmon, tuna, sardines, and trout, which contain important omega-3 and -6 fatty acids; and plant sources of fat, such as flaxseed.

"Now we'd like to find a way to keep some of the anti-inflammatory, positive effects that develop over time with a high-fat diet while reducing that diet's negative effects, such as high blood glucose and high triglycerides. It's possible that supplementing a high-fat diet with soluble fiber could do that, even delaying the onset of diabetes," he said.

This study is one of the first to provide two valuable lessons, said Sherry. The first, already noted, is that soluble fiber has direct anti-inflammatory effects and builds up the immune system. The second is that the amount of soluble fiber necessary to achieve these health benefits is a reasonable, not a pharmacological, amount.

The recommended daily dietary recommendation is 28 to 35 grams of total fiber, but most of the FDA's health claims are for insoluble fiber, and that's where things get a bit complicated, she said.

"Not all fiber is created equal, although you wouldn't know that by reading nutrition labels," said Sherry. "Most manufacturers don't tell you how much of each type of fiber a food contains, and we think it's important that this information be included on a product's packaging."

Good sources of soluble fiber are oat bran, barley, nuts, seeds, lentils, citrus fruits, apples, strawberries, and carrots. "We used a citrus-based pectin in our study," Sherry said.

Insoluble fiber, found in whole wheat and whole-grain products, wheat bran, and green, leafy vegetables, is also valuable for providing bulk and helping food move through the digestive system, but it doesn't provide the boost to the immune system that soluble fiber provides.
