Dr Roy Swank has provided evidence that a diet low in saturated fats (less than 15 g/day) combined with cod liver oil supplementation buy benzac 20gr mastercard acne los angeles, maintained over a long period of time buy generic benzac 20 gr skin care qvc, tends to retard the disease process, reduce the 23,24 number of attacks and decrease mortality. Oneopen-label pilot clinical trial evaluated the effects of a diet low in saturated fats supplemented with fish oil, vitamin B-complex 25 and vitamin C in subjects with newly diagnosed relapsing-remitting MS. After 2 years of this regimen the study reported a significant decrease from baseline values of relapse rates and disability scores. Preliminary reports from a recent randomized placebo- controlled pilot study evaluating a diet very low in saturated fat (less than 15%) supplemented with fish oil capsules found that, when compared with subjects following the American Heart Diet (less than 30% saturated fat) supplemented with placebo oil capsules, the treatment group had a significant decrease in relapse rate, disability and a 26 decrease in two inflammatory cytokines. These studies suggest that a diet very low in fat combined with fish oil supplementation may help to decrease relapse rates and increase time to disability in people with MS. Nutritional/dietary supplementation Many naturopaths use a variety of nutritional supplements usually as an adjunct to fundamental lifestyle therapies, such as diet, exercise and stress reduction (counseling) to address a specific symptom or condition. Under the DSHEA, dietary supplements are considered foods and not drugs and therefore regulated by the FDA as foods. Examples of substances that are considered dietary supplements include: fish, flax, evening primrose and borage oils, glandulars (usually made from animal sources), enzymes, melatonin and dehydroepiandrosterone (DHEA) (although these are hormones they are regulated and sold as dietary supplements in the USA), garlic capsules, soluble fiber, coenzyme Q10 (CoQ-10), L-carnitine, 5-hydroxytryptophan (5-HTP), etc. Obviously this is just a small fraction of the number and types of existing dietary supplements; the associated effects indicated below are rarely definitive. Cold-water fish and fish oil contain a high proportion of the omega-3 fatty acids and therefore contain a higher relative proportion of DHA and eicosapentaenoic acid. There have been at least two clinical trials evaluating the effectiveness of essential fatty acids (EFA) and DHA supplementation for dementia. The treatment group was given a mix of omega-6/ omega-3 fatty acids at a 4:1 ratio in which they received about 0. There were no cognitive measures in this study, and subjects were rated on 12 behavioral variables by their guardian. Although this study showed a positive benefit from short term EFA supplementation there were no objective measures in this study and no standard testing of cognitive function (e. The second, a double- blind placebo-controlled pilot study, evaluated the effects of 1 year of supplementation of 0. A significant increase in MMSE score was reported after 6 months of supplementation (control=19. There was a significant increase in both serum DHA and eicosapentaenoic acid levels after 3 months of supplementation. Amyotrophic lateral sclerosis: creatine Seven days of supplementation with creatine 20 g resulted in a transient increase in 35 maximal voluntary isometric muscular contraction and fatigue in 28 patients. Naturopathic medicine in neurological disorders 161 Bipolar disorder Four months of treatment with 9. Depression: ethyl-eicosapentaenoic acid There are two double-blind placebo-controlled pilot studies that have reported a significant improvement in depression in people on stable doses of antidepressants after 36,37 1–3 months of ethyl-eicosapentaenoic acid (E-EPA) supplementation. Depression: L-acetylcarnitine Two small studies in elderly depressed patients (n=24 and 28) showed effectiveness 38,39 without adverse effects. Depression: dehydroepiandrosterone There are two small controlled pilot studies of DHEA in depressed adults that have 40,41 reported benefit for that hormone. Epilepsy: melatonin 42–44 A small body of evidence suggests that melatonin may be useful in epilepsy. Melatonin has effects in sleep disorders and perhaps in chronic headache and may prove of use in depression and irritability, suggesting broad CNS effects. Epilepsy: polyunsaturated fatty acids (especially omega-3 fatty acids) In five patients, a reduction in frequency and intensity of epileptic seizures resulted from 45 adding 5 g of a 65% omega-3 fatty acid spread at breakfast for 6 months. Omega-3 fatty acids are increased in epileptic children on the ketogenic diet and correlate with resultant 46 decreased seizure activity. Headache: 5-hydroxytrytophan 5-HTP, a serotonin precursor, showed moderate efficacy and remarkable safety compared 50 to placebo in 31 patients with chronic primary headache and in 78 patients with chronic 51 tension headaches. In preference to methysergide or propranolol, owing to their side- effects, 5-HTP may be useful in reducing the frequency or intensity of migraines for 52,53 some patients. However, all patients on treatment improved, while all patients on placebo deteriorated. Insomnia: melatonin Although melatonin is a hormone, it is sold and regulated as a dietary supplement in the 55–65 USA. There are a fair number of studies demonstrating its effectiveness for insomnia, primarily in improving sleep latency.

For patients just starting on the therapy, initial sessions are usually only 10–15 minutes in length. Some patients with SAD undergo light therapy session two or three times a day, others only once. The time of day and number of times treatment is administered depends on the physical needs and lifestyle of the individual patient. If light therapy has been prescribed for the treatment of SAD, it typically begins in the fall months as the days begin to shorten, and continues throughout the winter and possibly the early spring. Patients with a long-stand- ing history of SAD are usually able to establish a time- table or pattern to their depressive symptoms, and can initiate treatment accordingly before symptoms begin. The light from a slanted light box is designed to focus on the table it sits upon, so patients may look down to read or do other sedentary activities during therapy. Patients using an upright light box must face the light source, and should glance toward the light source occa- sionally without staring directly into the light. The light sources in these light boxes typically range from • Full-spectrum/UV light therapy for disorders of the 2,500–10,000 lux (in contrast, average indoor lighting is skin.

These foundational principles are completely context independent buy benzac 20 gr line acne einstein, and have been referred to here as context determining because the context is bound into the wisdom purchase benzac 20 gr visa acne light therapy. A traditional view in finding information is to seek data, and this leads us to seek an appreciation of the relationship between data and information, and indeed between information and knowledge. Here, data can be processed into information (called data information) through the application of Copyright © 2005, Idea Group Inc. Copying or distributing in print or electronic forms without written permission of Idea Group Inc. Knowledge Cycles and Sharing 105 patterns of meaning that relate to organizational purpose. Data processing is also constrained by criteria of what constitutes a processing need. Information also exists phenomenally, through the very microstructural variety differentiation that exists in a structured situation. The model given in Figure 3 leads to questions about our under- standing of knowledge creation, and has consequences for the way in which we see knowledge development in organizations. For instance, how and through what means are the patterns of meaning formed that enable data to be processed, and information to be coalesced. Further exploration of knowledge processes within organizations can be developed within the context of knowledge management. There is a perhaps a better way than that of Figure 3 to describe the relationship between data, information and knowledge, that comes from an ontological model of viable systems that originates from Schwarz (1997). While data is not information, data classifications or classes can be described as entities that, when woven into a relational pattern can become information when conditioned by knowledge within an action setting. This occurs when information is analyzed, interconnected to other information within a thematic context, and compared to what is already known. A relationship between data, information, and knowledge cannot be considered indepen- dently of an agent that is involved in creating that relationship. Our interest lies in the generic relationship, rather than local detailed relationships between commodity ele- ments that will be different for each agent. It presupposes that the agent has a purpose for inquiry and is involved in the process of either quantitative or qualitative measurement. Qualitative measurement involves conceptual assessment brought together with some form of mapping agent that is capable of generating a possibly complex scale of values that can be assessed as though they are quantitative measurements.

However, the question of what constitutes knowledge management may be posed in different ways (Allee, 1997). A traditional meaning approach discusses questions of ownership, control, and value, with an emphasis on planning. Another view is that knowledge is organic, and has a flow, a self-organizing process, and patterns. Knowledge is increasingly recognized as an important organizational asset (Iles, 1999). Its creation, dissemination and application are often now seen as a critical source of competitive advantage (Allee, 1997; Lester, 1996). Cognitive elements operate through mental models that are working worldviews that develop through the creation and manipulation of mental analogies. Mental models like schemata, paradigms, perspectives, beliefs and viewpoints, according to Nonaka and Takeuchi, help individuals perceive and define their world. The technical element of tacit knowledge includes concrete know-how, crafts, and skills.
