Insufficient Levels Of Vitamin D Puts Elderly At Increased Risk Of Dying From Heart Disease - Science Daily, 9/21/09 - "Compared to those with optimal vitamin D status, those with low vitamin D levels were 3 times more likely to die from heart disease and 2.5 times more likely to die from any cause ... Dr. Ginde says the findings suggest that current daily recommendations of vitamin D may not be enough for older adults to maintain optimal health" - See vitamin D at Amazon.com.

Medications Effective In Reducing Risks For Breast Cancer Can Also Cause Serious Side Effects - Science Daily, 9/18/09 - "The most common side effects for tamoxifen are flushing and other vasomotor symptoms (e.g., night sweats, hot flashes), vaginal discharge and other vaginal symptoms such as itching or dryness; for raloxifene, side effects include vasomotor symptoms and leg cramps; and for tibolone, side effects include vaginal bleeding ... Tamoxifen increases risks of endometrial cancer, hysterectomies and cataracts compared with the other drugs. Tamoxifen and raloxifene increase risk of blood clots, although tamoxifen's risk is greater. Tibolone carries an increased risk of stroke"

Health Advice: Do Omega-3 Supplements Affect Mood? - US News and World Report, 9/18/09 - "Researchers have shown that depressed patients have, on average, lower levels of omega-3 in their blood than nondepressed individuals; furthermore, they have found evidence that greater severity of depression is linked to lower levels of omega-3. A number of well-controlled depression treatment studies have found therapeutic benefits following omega-3 supplementation. Omega-3 fatty acids also benefit patients with cardiovascular disease, and there is a very well-known association between depression and cardiovascular disease that may reflect a common factor for both: deficiencies in omega-3 fatty acids"

2 Easiest Ways to Catch Swine Flu - WebMD, 9/18/09 - "Having a sick person cough directly into your face ... That gives you more than a 50% chance of getting sick ...

Seniors may have immunity to swine flu - msnbc.com, 9/17/09 - "Researchers believe seniors have a partial immunity to swine flu because of exposure to similar viruses in their lifetimes. It is a rare bit of good news before the start of the regular flu season, which generally kills 36,000 people a year, most of them elderly" - Note:  For people that have been reading my newsletters, that first sentence is what I've been saying for some time.

Vitamin D, Calcium Shown to Reduce Mortality - Medscape, 9/17/09 - "Vitamin D and calcium have been shown to help lower mortality risk among older people, but the benefits are not necessarily explained by a reduced risk for hip fracture ... When given with vitamin D, calcium reduced mortality (hazard ratio [HR], 0.88 [0.81–0.97]; P < .01), whereas studies involving vitamin D alone showed no significant reduction in mortality" - See vitamin D at Amazon.com.

Metabolic Syndrome Risk Factors Drive Significantly Higher Health Care Costs - Science Daily, 9/17/09 - "Risk factors for metabolic syndrome, such as obesity, high blood pressure, and elevated blood lipid levels, can increase a person's healthcare costs nearly 1.6-fold, or about $2,000 per year. For each additional risk factor those costs rise an average of 24%"

Zinc Deficiencies A Global Concern - Science Daily, 9/17/09 - "One new study has found DNA damage in humans caused by only minor zinc deficiency ... Zinc deficiency is quite common in the developing world ... studies have shown that zinc is essential to protecting against oxidative stress and helping DNA repair – meaning that in the face of zinc deficiency, the body's ability to repair genetic damage may be decreasing even as the amount of damage is going up ... When prostate glands become cancerous, their level of zinc drops precipitously, and some studies have suggested that increasing zinc in the prostate may at least help prevent prostate cancer and could potentially be a therapeutic strategy. There are concerns about the relationship of zinc intake to esophageal, breast, and head and neck cancers. And the reduced zinc status that occurs with aging may also contribute to a higher incidence of infection and autoimmune diseases" - See Jarrow Zinc Balance at Amazon.com.

New Vitamin K Analysis Supports The Triage Theory - Science Daily, 9/17/09 - "An important analysis conducted by Children's Hospital Oakland Research Institute scientists suggests the importance of ensuring optimal dietary intakes of vitamin K to prevent age-related conditions such as bone fragility, arterial and kidney calcification, cardiovascular disease, and possibly cancer ... Average intakes of vitamin K in the United States and the United Kingdom are less even than currently recommended intakes, which are primarily based on levels to ensure adequate coagulation. McCann & Ames' analysis supports recommendations by some experts that non-clotting functions requiring vitamin K may need higher intakes than are currently recommended" - See vitamin K at Amazon.com.

Cases Of Liver Cancer Reduced In Younger Population Vaccinated For Hepatitis B - Science Daily, 9/16/09 - "A 20-year follow-up study revealed a dramatic drop in liver cancer cases among 6- to 19-year-olds who were vaccinated for the hepatitis B virus at birth"

New Evidence That Green Tea May Help Improve Bone Health - Science Daily, 9/16/09 - "The scientists exposed a group of cultured bone-forming cells (osteoblasts) to three major green tea components — epigallocatechin (EGC), gallocatechin (GC), and gallocatechin gallate (GCG) — for several days. They found that one in particular, EGC, boosted the activity of a key enzyme that promotes bone growth by up to 79 percent. EGC also significantly boosted levels of bone mineralization in the cells, which strengthens bones. The scientists also showed that high concentrations of ECG blocked the activity of a type of cell (osteoclast) that breaks down or weakens bones. The green tea components did not cause any toxic effects to the bone cells, they note" - See green tea extract at Amazon.com.

Supplementing Babies' Formula With DHA Boosts Cognitive Development, Study Finds - Science Daily, 9/15/09 - "children who were breast fed as infants have superior cognitive skills compared to those fed infant formula, and it's thought that this is due to an essential fatty acid in breast milk called docosahexaenoic acid (DHA) ... because infants who display superior performance on the means-end problem-solving task tend to have superior IQ and vocabulary later in childhood, it's possible that the beneficial effects of DHA extend well beyond infancy"

Survival Improves for Prostate Cancer - WebMD, 9/15/09 - "The death rate from prostate cancer within 10 years of diagnosis among men who did not have surgery or radiation was 2% to 6% in the 1990s ... This compares to disease-specific death rates of 15% to 23% in similarly aged men with similar disease characteristics who chose not have these treatments in the pre-PSA era ... PSA screening saves few lives and has led to unnecessary treatment for millions of men. Findings from several recent studies appear to have bolstered the claim"

Independent inverse relationship between serum lycopene concentration and arterial stiffness - Atherosclerosis. 2009 Aug 13 - "brachial-ankle pulse wave velocity (baPWV), a marker of arterial stiffness and markers of oxidative stress and inflammation ... Subjects in middle tertile (T2) and upper tertile (T3) had lower baPWV (1263+/-23 and 1265+/-14cm/s vs. 1338+/-21cm/s; p=0.009) and lower oxidized LDL (oxLDL) (53+/-3 and 55+/-3U/L vs. 66+/-3U/L; p<0.001) than those in lower tertile (T1). Subjects in T3 showed higher LDL particle size (24.3+/-0.08nm vs. 24.0+/-0.07nm, p=0.005) and lower C-reactive protein (hs-CRP) (0.80+/-0.25mg/dL vs. 1.27+/-0.24mg/dL, p=0.015), compared with those in T1. Logistic regression analysis showed that baPWV decreased with the increment of lycopene concentration; log baPWV decreased by 0.21cm/s (95% CI -0.168;-0.045, p=0.001) per unit change in lycopene ... the estimated effect was attenuated by 35% ... This study supports the presence of an independent inverse relationship between circulating lycopene and baPWV. Additionally, reduced oxidative modification of LDL may be one of mediators on the mechanisms how lycopene reduces arterial stiffness" - See Jarrow Lyco-Sorb (contains Lyco-O-Mato) at Amazon.com.

Insulin resistance and risk of incident hypertension among men - J Clin Hypertens (Greenwich). 2009 Sep;11(9):483-90 - "The insulin sensitivity index was 6% lower in the cases compared with the controls (P<.001). The multivariable odds ratio for hypertension comparing the lowest with highest quartile of insulin sensitivity index was 1.09 (0.71-1.65) among the entire sample. However, the association between the insulin sensitivity index and incident hypertension differed significantly by age (P interaction <.001). Among men younger than 60 years, the multivariable odds ratio for the lowest compared with highest quartile was 1.93 (1.01-3.71) but was 0.67 (0.37-1.24) among older men. Insulin resistance is independently associated with incident hypertension among younger men"

  • Diagnosis and treatment of vitamin D deficiency - vitamindcouncil.org - "It is important to understand that neither the regular consumption of recommended amounts of vitamin D (e.g., 100 IU/8-oz glass of milk) effectively prevents vitamin D deficiency [79,80]. Furthermore, 2000 IU/day for 1 year failed to achieve a 32 ng/ml target 25(OH)D concentration in 40% of 104 African-American women studied [81]. Even the administration of 4000 IU/day for > 6 months to middle-age Canadian endocrinology out-patients, resulted in average 25(OH)D levels of 44 ng/ml and produced no side effects other than an improved mood [70]. Heaney estimated that ~ 3000 IU/day of vitamin D is required to assure that 97% of Americans obtain levels > 35 ng/ml [43]. Healthy adult men use between 3000 and 5000 IU of vitamin D/day, if it is available [82]"

  • Understanding The Anticancer Effects Of Vitamin D3 - Science Daily, 7/6/09 - "the active form of vitamin D3 directly activates the CST5 gene in human colon cancer cell lines, increasing levels of cystatin D protein. Functionally, cystatin D was shown to inhibit the growth of human colon cancer cells lines in vitro and when they were xenotransplanted into mice. As knocking down expression of cystatin D in human colon cancer cell lines rendered them unresponsive to the antiproliferative effects of the active form of vitamin D3, the authors conclude that CST5 is a candidate tumor suppressor gene and that it mediates a large proportion of the anticancer effects of the active form of vitamin D3"

  • Vitamin D Insufficiency Linked To Bacterial Vaginosis In Pregnant Women - Science Daily, 5/21/09 - "Bacterial vaginosis (BV) is the most common vaginal infection in US women of childbearing age, and is common in pregnant women. BV occurs when the normal balance of bacteria in the vagina is disrupted and replaced by an overgrowth of certain bacteria ... Overall, women with BV had lower serum 25(OH)D concentrations than those without BV (P < 0.01). The prevalence of BV decreased as vitamin D concentration increased to 80 nmol/L (P < 0.001). Compared with 75 nmol/L, serum 25(OH)D concentrations of 20 nmol/L and 50 nmol/L were associated with 65% and 26% increases, respectively, in the likelihood of BV. In summary, these findings suggest that vitamin D insufficiency is associated with BV in the first 4 mo of pregnancy. Further, poor vitamin D status may contribute to the strong racial disparity in the prevalence of BV in US women"
