Muscle Massage Rubs Out Inflammation

Medpagetoday.com REPORTS HERE that "heavily stressed muscles responded to massage therapy with a variety of biologic changes associated with reduced inflammation, analysis of tissue specimens showed."

"Serial quadriceps-muscle biopsies showed reduced production of the pro-inflammatory cytokines tumor necrosis factor (TNF)-alpha and interleukin-6 (IL-6) following massage treatment of exercise-induced muscle damage. Massage also was associated with activation of signaling pathways involved in stretch response and mitochondrial biogenesis, as reported online in Science Translational Medicine."

"Our findings suggest that the perceived positive effects of massage are a result of an attenuated production of inflammatory cytokines, which may reduce pain by the same mechanism as conventional anti-inflammatory drugs such as NSAIDs."

"These results elucidate the biological effects of massage in skeletal muscle and provide evidence that manipulative therapies may be justifiable in medical practice."

"The role of complementary and alternative medicine, including massage therapy, has expanded greatly as an adjunct to conventional medical practice. For many of the techniques, however, there is limited evidence regarding cellular or mechanistic effects to support their clinical use, the authors wrote in their introduction."

"Massage therapy has been widely used as an aid to reduce pain and promote recovery of injured muscles. Hypothesized effects of massage have included moderation of inflammation, improved blood flow, and reduced tissue stiffness, all contributing to pain reduction, the authors continued. The functional benefits of massage have remained unclear and controversial. Experiments in preclinical models have limited applicability because of their failure to mimic human responses. Despite reported long-term benefits of massage in chronic pain and range of motion, the biologic basis has eluded explanation."

"Overall, this profile suggested that massage altered processes related to the cytoskeleton and to inflammation, with the former process being activated early after massage and the latter induced later in recovery," the authors wrote.

"Massage had no effect on key regulators of growth signaling and metabolite accumulation, including lactate, glycogen, proglycogen, and macro glycogen."

"Also after the post-massage recovery period, the authors found increased expression of COX7B and ND1 mRNA -- which are encoded by nuclear and mitochondrial genes and transcriptionally activated by PGC-1-alpha -- 'confirming that mitochondrial biogenesis signaling was augmented by massage therapy.'"

"In the immediate post-massage period, pro-inflammatory NF-kappa-B signaling was diminished. After the post-massage recovery period, phosphorylation of heat-shock protein 27 (a marker of cellular stress) was reduced compared with the control situation, as were concentrations of interleukin-6 and tumor necrosis factor-alpha."

Clinical Trial Data Should Be Open for Review
Published 04/30/2012 - 3:14 p.m.  CDT

Original clinical study reports, which contain far more detail than published randomized trials, should be made available to independent researchers seeking to verify efficacy and safety claims.

In support of this argument, the history of the influenza antiviral oseltamivir (Tamiflu), which was approved by the FDA in 1999, was cited. The widespread belief in oseltamivir's efficacy, was based on a meta-analysis of 10 trials conducted by the manufacturer prior to licensure.  But the authors pointed out that the FDA, which was aware of these clinical trials, concluded that oseltamivir had not been shown to reduce complications and required a statement on the drug's label to that effect.  Moreover, oseltamivir was not given an FDA indication for prevention of spread of influenza.

To this, [authors] commented, "If FDA is right, the drug's effectiveness may be no better than aspirin or acetaminophen.'"

HR 329 in need of Co Sponsors
Published 04/30/2012 - 11:11 a.m.  CDT

Representative Bob Filner recently introduced the Chiropractic Care to All Veterans Act (H.R. 329). The bill would require the Veterans Administration (VA) to have a chiropractic physician on staff at all major VA medical facilities by 2014. You too can help ensure chiropractic care is available to those who have placed their lives in service to our country. H.R. 329 is in need of cosponsors to assist its likelihood of passage.

Court Sides with Generic-Drug Makers
Published 04/25/2012 - 6:33 a.m.  CDT

In a unanimous decision, the Supreme Court ruled that generic drugmaker Caraco Pharmaceutical Laboratories can sue Novo Nordisk for what Caraco says are exaggerated descriptions of the scope of patents Novo Nordisk holds on a diabetes drug.

A group of Democratic senators has introduced a bill that would allow people to sue generic drugmakers over failing to update their drug labels to include all known risks. The bill is meant to counter last year's Supreme Court decision in a generic drug dispute.

An $8 billion Medicare demonstration program is poorly designed and should be cancelled, the nonpartisan Government Accountability Office (GAO) said. The program is designed to reward the highest-quality Medicare Advantage plans, but instead pays out most of its award money to mediocre plans, according to a report.


Ethiopia and Kenya Trips.  Have you ever wanted to provide chiropractic care in another country and give back to those in need?

Dr. Teresa Jones has been volunteering on mission trips to Africa for 4 years and is reaching out to the District 5 for help this year. There are two chances to participate, both in July 2012 and if you are interested please RSVP to frontdesk@wholehealth-care.com to let her know you area interested!


The Patient-Centered Outcomes Research Initiative (PCORI), established by the 2010 Patient Protection and Affordable Care Act, has set five priorities as the group's research agenda for the coming years, with the overall goal of advancing clinical effectiveness research. …. the priorities [are] as follows...

Girls who face multiple social stressors at home as toddlers are more likely to be obese by age 5, researchers found.

Nonpharmacologic pain management appears to be safe for mother and baby, although there is limited published evidence to explain its efficacy, according to a Cochrane Review.

There is more data to support the ef?cacy of pharmacologic pain management, such as epidurals and opioids, but these methods lead to more adverse effects.  This reports reports upon some of these
Regulators on both sides of the Atlantic were slow to inform patients and their doctors about problems with metal-on-metal hip implants and relied on industry officials and consultants in crafting their responses.

Complications included high failure rates and possible systemic effects from elevated metal ion levels in the blood.  An advisory has been issued to surgeons, telling them that patients who have received metal-on-metal implants should have annual checkups for life. The evaluations should include testing for metal ions in the blood as well as for clinical symptoms of device failure.
