Increased Yin-Deficient Symptoms and Aggravated Autonomic Nervous System Function in Patients with Metastatic Cancer.

This is a truly fascinating study. It is a veritable "East Meets West" extravaganza. They are looking at both symptoms of Yin Deficiency and Autonomic dysfunction as measured by Heart Rate Variability, and metastastic disease. Yin deficiency is a part of some very prominent conditions in Traditional Chinese Medicine for example, Tuberculosis, High Blood Pressure, Menopausal Hot Flashes. As an anecdotal example, one of my current patients being treated for hypertension had remarkable and sustained lowering of both systolic and diastolic blood pressure with the addition of a powerful Yin tonic. To try to correlate the symptoms of Yin Deficiency with metastasis, not only broadens the reach of TCM diagnosis, but adds to our understanding of the yin yang imbalance. What drew my attention to it was the attention paid to Autonomic Dysfunction and it is food for thought that there was a definite correlation with Yin Deficiency and autonomic imbalance. It gives us one more lens to try to make sense of vexing conditions that be difficult to treat.

Abstract Objectives: The objectives of this study were to investigate the
differences in severity of yin-deficiency syndrome (YDS) and function of the
autonomic nervous system (ANS) between patients with cancer with metastasis and
those without metastasis. ...
Interventions: The severity of YDS in each subject was evaluated using a questionnaire containing 12 items about symptoms and signs related to YDS. The severity of each symptom or sign was rated on a 4-point scale. Outcome measures: The total score on the questionnaire represented the severity of YDS. ANS function in each subject was evaluated by measuring heart rate variability (HRV), including time and frequency domains. ...
Results: The patients with metastasis had significantly higher average total YDS score and heart rate compared with the patients without metastasis. In contrast, they had significantly lower HRV, including standard deviation of the 5-minute average R-R
interval, total power, very-low-frequency power, and low frequency (LF) power,but not high-frequency (HF) power and LF/HF ratio. Conclusions: The results of this study indicate that patients with metastatic cancer have more severe YDS and
impaired ANS function than those without metastasis.

Do Marathons Wreck Your Knees?

I feel obliged to link to this article since knee arthritis is one of the most studied uses for acupuncture and because I have a number of marathon runners as patients. The upshot seems to be that there is no conclusive evidence that marathons hurt your knees. In fact, active participants had less cartilage loss in their knees than sedentary counterparts. The active ones also had more bone spurs, and some microscopic changes in the cartilage, but their significance is uncertain and could be a positive adaptation. I like this conclusion and it makes sense to me, frankly. Of course any one person can have dramatically different outcomes, and I can't help wonder if the conditions under which you run makes a difference too.

Alcohol Intake and Acupuncture in.... rats...

I just love this study. It is a study done in South Korea in conjunction with Brigham Young University published in Alcohol Clinical Experimental Research. 2010 Sep 2. The title of the study is "Acupuncture Inhibits GABA Neuron Activity in the Ventral Tegmental Area and Reduces Ethanol Self-Administration." (But I thought Mormon's didn't drink? I kid.)
They used one single acupuncture point, Heart 7, and found that needling this point decreased the rats' self administration of alcohol. Their conclusions were "These findings suggest that DOR-mediated opioid modulation of VTA GABA neurons may mediate acupuncture's role in modulating mesolimbic DA release and suppressing the reinforcing effects of ethanol."

They did look at the ventral tegmental area GABA neuron firing rate. I only have access to the abstract, so do not know how they managed all of it, but it tells me something that I've certainly seen clinically. That is that acupuncture can help to decrease alcohol intake. Now I know why. A hearty "thank you" to the researchers and rats involved in this really interesting experiment. Now I know how to explain this to my patients! It's their ventral tegmental area GABA neuron firing that was modified!

Acupuncture article in NYtimes: Acupuncture and Osteoarthritis of the Knee Another Look

I've been meaning to comment on this blog post from the New York Times http://well.blogs.nytimes.com/2010/08/23/studying-acupuncture-one-needle-prick-at-a-time/?scp=4&sq=acupuncture&st=cse for some time now. It covers a number of issues concerning acupuncture research. It first cites a recent study from MD Anderson School of Medicine exploring osteoarthritis of the knee and the effectiveness of acupuncture. The link to that article is here.http://onlinelibrary.wiley.com/doi/10.1002/acr.20225/abstract. The study is actually trying to determine if the clinical attention given to the patients affected outcome, thus getting at the ever present problem of "placebo" in acupuncture research. What they found in the study is that acupuncture worked about the same as sham acupuncture. Because of that, the study's lead author concludes that acupuncture does not work, since in your typical drug study if the drug works the same as a placebo the determination is that the drug does not work. ( We will leave aside the issue that many drugs on the market now,Prozac for example, work no better than placebo and still enjoy widespread use.) But another way to parse the outcome of the study is that acupuncture works even if poorly administered. In this particular study the sham acupuncture was less stimulative, shallow needling, so the acupuncture defenders can claim that acupuncture was performed. The NYTimes article goes on to mention the German Insurance Company studies which showed that drug (analgesic) usage was dramatically reduced with acupuncture and sham acupuncture in back pain patients versus the controls, and that only 15% of acupuncture patients needed pain medication versus 29% of sham 59% of controls. German Insurance Companies now pay for acupuncture as a result of these studies, btw. The article also mentions the study comparing effexor to acupuncture covered in this blog post.(http://www.blogger.com/post-edit.g?blogID=6188135334037051688&postID=1694074355474832229)
The placebo issue still plagues acupuncture research, and keeps the discussion from going further than whether we can trust the studies, and then whether acupuncture really works or not. It gets tiresome, especially given the scant funding for acupuncture research. One veteran British acupuncture researcher I met at the latest Society for Acupuncture Research conference is recommending that we simply design studies comparing one dosage of acupuncture (time, frequency, length of treatment, point selection) to another so we can finally get beyond the underlying premise of the MD Anderson study, ie that it's the clinical setting or attitude that is determining outcome. You would think that the animal studies would put some of the placebo chatter to rest a bit, but it doesn't seem to.
I have no interest in dispensing placebos, nor am I interested in delivering acupuncture using specific points, if it would be just as effective to use any random points on everyone. It would save lots of time and the effort of charting. I am dedicated to studying and learning what the actual mechanisms of acupuncture are so that we can use it more effectively in a no nonsense approach. If studies repeatedly indicate that one point is as good as another, so be it. But I don't think we're there yet.
In the spirit of "first doing no harm" however, I wish that other treatment modalities were held to the high standard that acupuncture is and were better scrutinized for bias, placebo and safety.
