H-Wave® effects on blood flow and angiogenesis in longitudinal studies in rats.

Effects of repeated H-Wave® device stimulation (HWDS) on blood flow and angiogenesis in the rat hind limb were studied. The hypothesis tested was that HWDS acutely increases hind limb blood flow, and that repeated HWDS would elicit angiogenesis. Animals were HWDS-conditioned (``Conditioned'') or sham-stimulated (``Sham'') (n = 5/group) daily for 3 weeks. The contralateral limb in both groups served as the control. Each animal was injected with bromodeoxyuridine (BrDU). After 3 weeks, rats were anesthetized and iliac artery blood flow was measured bilaterally before, during, and after acute HWDS. HWDS of the Conditioned limbs elicited a 247% increase in blood flow above resting conditions compared to a 200% increase in control legs. Sham animals did not demonstrate between-leg differences in flow. Hindlimb musculature staining for BrDU revealed angiogenesis in Conditioned versus Sham groups. Flow changes accompanying HWDS corroborated earlier microvascular findings demonstrating a significant striated muscle arteriolar dilation with HWDS.

A potential role for avocado- and soybean-based nutritional supplements in the management of osteoarthritis: a review.

Osteoarthritis (OA) is a common, painful, and debilitating condition that affects approximately 46.4 million individuals in the United States. By 2012, this number is expected to increase to 60 million. In addition, it is the leading cause of activity limitation in adults and represents a widely acknowledged economic burden. Although the ultimate goal is to slow or prevent OA progression, at present, medical management of OA is aimed primarily at controlling symptoms of pain and stiffness and maintaining joint mobility and quality of life. Because of the lack or perceived lack of response to many conventional therapies for OA as well as concerns regarding the long-term administration of drugs (eg, nonsteroidal anti-inflammatory drugs), oral joint health supplements (OJHSs) have become increasingly popular among patients with OA. This article briefly reviews pertinent molecular mechanisms involved in the development of OA and summarizes available in vitro and in vivo evidence supporting the use of avocado and soybean unsaponifiables (ASU) either alone or in combination with glucosamine and chondroitin sulfate in patients with OA. Basic scientific research studies and a systematic review and meta-analysis of the available high-quality randomized clinical trials indicate that 300 mg of ASU per day (with or without glucosamine and chondroitin sulfate) appears to be beneficial for patients with hip or knee OA. There is also some evidence that ASU or ASU/glucosamine/chondroitin sulfate combination products could be used prophylactically in even the earliest stages of OA. Considering concerns regarding inferior-quality OJHSs, consumers and physicians are encouraged to take an evidence-based approach when evaluating OJHSs to identify and recommend safe and effective products that meet label claims when tested independently, and are of the highest quality.

Nutrigenomic targeting of carbohydrate craving behavior: can we manage obesity and aberrant craving behaviors with neurochemical pathway manipulation by Immunological Compatible Substances (nutrients) using a Genetic Positioning System (GPS) Map?

Genetic mediated physiological processes that rely on both pharmacological and nutritional principles hold great promise for the successful therapeutic targeting of reduced carbohydrate craving, body-friendly fat loss, healthy body recomposition, and overall wellness. By integrating an assembly of scientific knowledge on inheritable characteristics and environmental mediators of gene expression, we review the relationship of genes, hormones, neurotransmitters, and nutrients as they correct unwanted weight gain coupled with unhappiness. In contrast to a simple one-locus, one-mechanism focus on pharmaceuticals alone, we hypothesize that the use of nutrigenomic treatment targeting multi-physiological neurological, immunological, and metabolic pathways will enable clinicians to intercede in the process of lipogenesis by promoting lipolysis while attenuating aberrant glucose cravings. In turn, this approach will enhance wellness in a safe and predictable manner through the use of a Genetic Positioning System (GPS) Map. The GPS Map, while presently incomplete, ultimately will serve not only as a blueprint for personalized medicine in the treatment of obesity, but also for the development of strategies for reducing many harmful addictive behaviors and promoting optimal health by using substances compatible with the body's immune system.

H-Wave induces arteriolar vasodilation in rat striated muscle via nitric oxide-mediated mechanisms.

H-Wave electrical device stimulation (HWDS) is used clinically to expedite recovery from soft tissue injuries. We hypothesized that HWDS induces arteriolar dilation, a mechanism involved in the healing process. Acute effects of HWDS on striated muscle arteriolar diameters were studied. Arteriolar diameters were measured in the cremaster muscle of 57 male anesthetized rats using intravital microscopy before and after HWDS or sham stimulation (SS) at 1 or 2 Hz for periods of 30-60 min. In a separate cohort, the role of nitric oxide (NO) in the response to HWDS was assessed by blocking NO synthase using topical L-NAME at 10(-5) M. Maximal arteriolar responses to stimulation were compared to prestimulation diameters. HWDS both at 1 and 2 Hz resulted in significant arteriolar vasodilation (p < 0.05). The arterioles in SS animals demonstrated no changes in diameter. Similarly, microvascular diameters did not change with HWDS following blockade of NO production. Because of Poiseuille's Law, the significant arteriolar dilation induced by HWDS would translate into increases in blood flow of 26-62%. In addition, lack of arteriolar dilation following HWDS with blockade of NO production suggests that NO plays a role in the microvascular response to HWDS. These studies suggest that arteriolar vasodilation accompanying HWDS may result in increased perfusion, contributing to the observed therapeutic effects of HWDS.

Return to fitness.

The cornerstone of personal health is prevention. The concept of exercise as medicine is a lesson I have preached throughout my career, both with my patients in my private practice as well as through my years working with athletes at all levels including the Philadelphia 76ers basketball team and the Pennsylvania Ballet. It is also a message I relayed as a Special Advisor to the President's Council on Physical Fitness and Sports (PCPFS) during the first Bush administration, working closely with my old friend-and fitness advocate and visionary himself-Governor Arnold Schwarzenegger, who served as Chairman to the PCPFS. Arnold's impact on our nation's health was an extremely positive one that was felt in communities from coast-to-coast. Exercise, activity, and prevention were key components of his prescription for change and improved health for our country. He has also always personally inspired me to see my role as a physician and "healer" in a much broader context.

H-Wave, a nonpharmacologic alternative for the treatment of patients with chronic soft tissue inflammation and neuropathic pain: a preliminary statistical outcome study.

The burden of chronic soft tissue inflammation and neuropathic pain on individuals and society is substantial. This study was conducted to evaluate the H-wave device--an innovative form of treatment for chronic pain and inflammation--in patients with persistent pain associated with injuries or conditions affecting the upper or lower extremities or the back. Patients with at least moderate pain despite conventional therapy were included in a systematic survey after they had been given 2 to 6 wk of treatment with the H-wave device. Measures of improvement involved the proportion of patients with diminished medication requirements, improved function, or pain relief greater than 25%. More than 60% of patients with pain in the lower extremities, upper extremities, or back experienced pain relief exceeding 25%. The proportion of patients whose function improved and who were able to perform a new activity was consistently greater than 50% across the 3 anatomic subgroups. More than 40% of patients in each group were able to reduce or completely eliminate the use of pain medications. These benefits of treatment were independent of the type of pain therapy administered previously. In each anatomic subgroup, the proportion of patients who reported improvement on more than 1 of the 3 endpoints was significantly higher than the expected response to placebo therapy (P<.001). Results suggest that the H-wave device provided important benefits to patients with chronic soft tissue inflammation and neuropathic pain.

Comparative analysis of individuals with and without chiropractic coverage: patient characteristics, utilization, and costs.

BACKGROUND: Back pain accounts for more than $100 billion in annual US health care costs and is the second leading cause of physician visits and hospitalizations. This study ascertains the effect of systematic access to chiropractic care on the overall and neuromusculoskeletal-specific consumption of health care resources within a large managed-care system. METHODS: A 4-year retrospective claims data analysis comparing more than 700 000 health plan members with an additional chiropractic coverage benefit and 1 million members of the same health plan without the chiropractic benefit. RESULTS: Members with chiropractic insurance coverage, compared with those without coverage, had lower annual total health care expenditures ($1463 vs $1671 per member per year, P<.001). Having chiropractic coverage was associated with a 1.6% decrease (P = .001) in total annual health care costs at the health plan level. Back pain patients with chiropractic coverage, compared with those without coverage, had lower utilization (per 1000 episodes) of plain radiographs (17.5 vs 22.7, P<.001), low back surgery (3.3 vs 4.8, P<.001), hospitalizations (9.3 vs 15.6, P<.001), and magnetic resonance imaging (43.2 vs 68.9, P<.001). Patients with chiropractic coverage, compared with those without coverage, also had lower average back pain episode-related costs ($289 vs $399, P<.001). CONCLUSIONS: Access to managed chiropractic care may reduce overall health care expenditures through several effects, including (1) positive risk selection; (2) substitution of chiropractic for traditional medical care, particularly for spine conditions; (3) more conservative, less invasive treatment profiles; and (4) lower health service costs associated with managed chiropractic care. Systematic access to managed chiropractic care not only may prove to be clinically beneficial but also may reduce overall health care costs.
