And Now for some news ….
Exercise and Immune System Benefits
Researchers may soon be able to add yet another item to the list of exercise’s well-documented health benefits: A preliminary study suggests that when cancer survivors exercise for several weeks after they finish chemotherapy, their immune systems remodel themselves to become more effective, potentially fending off future incidences of cancer.
The finding may help explain why exercise can significantly reduce the chances of secondary cancers in survivors or reduce the chances of cancer altogether in people who have never had the disease.
Researchers analyzed T cells in the blood of cancer survivors before and after a 12-week exercise program. They found that a significant portion of these immune cells converted from a senescent form, which isn’t as effective at combating disease, to a naïve form, ready to fight cancer and infections.
Their poster presentation entitled, “Effect of Exercise on T Cells in Cancer Survivors,” was recently discussed at The Integrative Biology of Exercise VI meeting – http://bit.ly/OrMFtN
Study leader Laura Bilek explains that previous research had turned up a variety of positive associations between exercise and cancer—notably, that exercise can reduce the risk of getting initial incidences of several different types of cancers, can often improve prognosis in cancer patients, and can reduce the risk of recurrence and secondary cancers survivors of some types of cancers. However, the mechanism behind these phenomena has been unknown.
She adds that this finding highlights the importance of exercise for all, including those with cancer and cancer survivors.
Remember to discuss all Exercise modifications with your Qualified Health Care Provider.

Exercise and Memory
A short burst of moderate exercise enhances the consolidation of memories in both healthy older adults and those with mild cognitive impairment, scientists with UC Irvine’s Center for the Neurobiology of Learning & Memory have discovered.
Most research has focused on the benefits of a long-term exercise program on overall health and cognitive function with age. But the UCI work is the first to examine the immediate effects of a brief bout of exercise on memory.
“The current findings offer a natural and relatively safe alternative to pharmacological interventions for memory enhancement in healthy older individuals as well as those who suffer from cognitive deficits,” Segal noted.
“With a growing population of the aged, the need for improvement of quality of life and prevention of mental decline is more important than ever before.”
Study results appear in the November issue (Volume 32, Number 4) of the Journal of Alzheimer’s Disease.
As always, discuss all Exercise recommendations with your Qualified Health Care Provider.

Spinal Fusion and Chronic Low Back Pain
Spinal fusion is a common but controversial treatment for chronic low back pain (LBP) with outcomes similar to those of programmed conservative care. To improve the results of fusion, tests for patient selection are used in clinical practice.
A recent article in The Spine Journal, was published to determine the prognostic accuracy of tests for patient selection that are currently used in clinical practice to identify those patients with chronic LBP who will benefit from spinal fusion.
The Systematic review of the literature. included studies that compared the results of magnetic resonance imaging (MRI), provocative discography, facet joint blocks, orthosis immobilization, and temporary external fixation with the clinical outcome of patients who underwent spinal fusion for chronic LBP.
The study’s outcome measures were to determine the prognostic accuracy of tests to predict the clinical outcome of spinal fusion in terms of sensitivity, specificity, and likelihood ratios (LRs).
The study concluded that no subset of patients with chronic LBP could be identified for whom spinal fusion is a predictable and effective treatment. Best evidence does not support the use of current tests for patient selection in clinical practice.
Discuss all Spinal Treatment options with your Doctor of Chiropractic.
