ROCHESTER, Minn. — A new study has found that the amount of vitamin D (http://www.mayoclinic.org/news2008-mchi/4904.html) in patients being treated for diffuse large B-cell lymphoma (http://www.mayoclinic.org/non-hodgkins-lymphoma/)was strongly associated with cancer progression and overall survival. The results will be presented at the annual meeting of the American Society of Hematology (http://www.hematology.org/) in New Orleans. "These are some of the strongest findings yet between vitamin D and cancer outcome," says the study's lead investigator, Matthew Drake, M.D., Ph.D., (http://www.mayoclinic.org/bio/13726218.html) an endocrinologist at Mayo Clinic in Rochester. "While these findings are very provocative, they are preliminary and need to be validated in other studies....

Early research findings may lead to new treatments for the diseaseUCLA scientists and colleagues from UC Riverside and the Human BioMolecular Research Institute have found that a form of vitamin D, together with a chemical found in turmeric spice called curcumin, may help stimulate the immune system to clear the brain of amyloid beta, which forms the plaques considered the hallmark of Alzheimer's disease. The early research findings, which appear in the July issue of the Journal of Alzheimer's Disease, may lead to new approaches in preventing and treating Alzheimer's by utilizing the property of vitamin D3 — a form...

Vitamin D Tied to Hypertension, Hyperglycemia: Teens with the lowest vitamin D levels had low HDL, metabolic syndrome, and high triglicerides. Low serum levels of vitamin D were linked to increased blood pressure, hyperglycemia, and obesity in an analysis of more than 3,500 American teenagers, a link previously seen in adults. “Vitamin D plays a useful role in general human health. We are just now beginning to understand the role that vitamin D may play in cardiovascular health,” said Dr. Jared P. Reis, who presented a poster on the associations of vitamin D levels and cardiovascular risk factors at a...

Vitamin D supplements may help prevent fractures in people over 65, provided they take enough of the right kind. A new review of clinical trials appears to show a strong dose-dependent effect for vitamin D in lowering the risk for nonvertebral fractures in the elderly. --snip-- The type of vitamin D made a difference. The effect of vitamin D3 was significant, with a 23 percent risk reduction, but there was no significant reduction with vitamin D2. The authors suggest that D3 is more effective in maintaining blood levels of 25-hydroxyvitamin D, the active form that the supplement takes in the...

Men With Vitamin D Deficiency May Have Increased Risk Of Heart Attack ScienceDaily (Jun. 11, 2008) — Low levels of vitamin D appear to be associated with higher risk of myocardial infarction (heart attack) in men, according to a new report. Studies have shown that the rates of cardiovascular disease-related deaths are increased at higher latitudes and during the winter months and are lower at high altitudes, according to background information in the article. "This pattern is consistent with an adverse effect of hypovitaminosis D [vitamin D deficiency], which is more prevalent at higher latitudes, during the winter and at...

The claims have been sensational. Martin Mittelstaedt checks up on the research behind the hypeIn the summer of 1974, brothers Frank and Cedric Garland had a heretical brainwave. The young epidemiologists were watching a presentation on death rates from cancer county by county across the United States. As they sat in a lecture hall at Johns Hopkins University in Baltimore looking at the colour-coded cancer maps, they noticed a striking pattern, with the map for colon cancer the most pronounced. Counties with high death rates were red; those with low rates were blue. Oddly, the nation was almost neatly divided...

Vitamin D Deficiency Study Raises New Questions About Disease And Supplements ScienceDaily (Jan. 27, 2008) — Low blood levels of vitamin D have long been associated with disease, and the assumption has been that vitamin D supplements may protect against disease. However, this new research demonstrates that ingested vitamin D is immunosuppressive and that low blood levels of vitamin D may be actually a result of the disease process. Supplementation may make the disease worse. In a new report Trevor Marshall, Ph.D., professor at Australia’s Murdoch University School of Biological Medicine and Biotechnology, explains how increased vitamin D intake affects...

In early April of 2005, after a particularly rainy spring, an influenza epidemic (epi: upon, demic: people) exploded through the maximum-security hospital for the criminally insane where I have worked for the last ten years. It was not the pandemic (pan: all, demic: people) we all fear, just an epidemic. The world is waiting and governments are preparing for the next pandemic. A severe influenza pandemic will kill many more Americans than died in the World Trade Centers, the Iraq war, the Vietnam War, and Hurricane Katrina combined, perhaps a million people in the USA alone. Such a disaster would...

The Antibiotic VitaminDeficiency in vitamin D may predispose people to infection Janet Raloff In April 2005, a virulent strain of influenza hit a maximum-security forensic psychiatric hospital for men that's midway between San Francisco and Los Angeles. John J. Cannell, a psychiatrist there, observed with increasing curiosity as one infected ward after another was quarantined to limit the outbreak. Although 10 percent of the facility's 1,200 patients ultimately developed the flu's fever and debilitating muscle aches, none did in the ward that he supervised. WINTER WOES. Cold-weather wear and the sun's angle in the winter sky limit how much ultraviolet...
