    Meta-analysis of prospective cohort studies evaluating the association of saturated fat with cardiovascular disease.
    Siri-Tarino PW, Sun Q, Hu FB, Krauss RM.
    Am J Clin Nutr. 2010 Jan 13. [Epub ahead of print]
    PMID: 20071648
    doi:10.3945/ajcn.2009.27725

    Conclusions: A meta-analysis of prospective epidemiologic studies showed that there is no significant evidence for concluding that dietary saturated fat is associated with an increased risk of CHD or CVD. More data are needed to elucidate whether CVD risks are likely to be influenced by the specific nutrients used to replace saturated fat.

    NEUROACTIVE STEROIDS: EFFECTS AND MECHANISMS OF ACTION
    doi:10.1016/j.psyneuen.2009.07.003

    This is a mini-review of vitamin D3, its active metabolites and their functioning in the central nervous system (CNS), especially in relation to nervous system pathologies and aging. The vitamin D3 endocrine system consists of 3 active calcipherol hormones: calcidiol (25OHD3), 1α-calcitriol (1α,25(OH)2D3) and 24-calcitriol (24,25(OH)2D3). The impact of the calcipherol hormone system on aging, health and disease is discussed. Low serum calcidiol concentrations are associated with an increased risk of several chronic diseases including osteoporosis, cancer, diabetes, autoimmune disorders, hypertension, atherosclerosis and muscle weakness all of which can be considered aging-related diseases. The relationship of many of these diseases and aging-related changes in physiology show a U-shaped response curve to serum calcidiol concentrations. Clinical data suggest that vitamin D3 insufficiency is associated with an increased risk of several CNS diseases, including multiple sclerosis, Alzheimer's and Parkinson's disease, seasonal affective disorder and schizophrenia. In line with this, recent animal and human studies suggest that vitamin D insufficiency is associated with abnormal development and functioning of the CNS. Overall, imbalances in the calcipherol system appear to cause abnormal function, including premature aging, of the CNS.

    "For what reason I don't know, but this January 2009 editorial by William Faloon of the Life Extension Foundation is making the rounds. Perhaps it just came available on the web.

    It's a good read, particularly in light of the billions and trillions of dollars the thieves & thugs in DC are about to flush down the crapper on your behalf. Some notable excerpts.

    A large number of new vitamin D studies have appeared in the scientific literature since I wrote my plea to the federal government. These studies don't just confirm what we knew 16 months ago-they show that optimizing vitamin D intake will save even more lives than what we projected.

    For instance, a study published in June 2008 showed that men with low vitamin D levels suffer 2.42 times more heart attacks. Now look what this means in actual body counts.

    Each year, about 157,000 Americans die from coronary artery disease-related heart attacks. Based on this most recent study, if every American optimized their vitamin D status, the number of deaths prevented from this kind of heart attack would be 92,500.

    To put the number of lives saved in context, tens of millions of dollars are being spent to advertise that Lipitor® reduces heart attacks by 37%. This is certainly a decent number, but not when compared with how many lives could be saved by vitamin D. According to the latest study, men with the higher vitamin D levels had a 142% reduction in heart attacks."

    C-reactive protein concentration and risk of coronary heart disease, stroke, and mortality: an individual participant meta-analysis.
    The Lancet, Early Online Publication, 22 December 2009
    doi:10.1016/S0140-6736(09)61717-7

    Interpretation
    CRP concentration has continuous associations with the risk of coronary heart disease, ischaemic stroke, vascular mortality, and death from several cancers and lung disease that are each of broadly similar size. The relevance of CRP to such a range of disorders is unclear. Associations with ischaemic vascular disease depend considerably on conventional risk factors and other markers of inflammation.

Well - A Call for Caution in the Rush to Statins - NYTimes.com - 0 views

  •  
    Judging by recent headlines, you might think so. Last week heart researchers reported that millions of healthy people could benefit from taking statins even if they don't have high cholesterol.\n\nAlthough many doctors hailed the study as a major breakthrough, a closer look at the research suggests that statins (like Crestor, from AstraZeneca, and Lipitor, from Pfizer) are far from magic pills. While they clearly save lives in people with a previous heart attack or other serious heart problems, for an otherwise healthy person the potential benefit remains small.

Cholesterol-Fighting Drugs Show Wider Benefit - New York Times - 0 views

  •  
    CHART: Statins Reduce Risks: A study of 18,000 people with high levels of C-reactive protein, or CRP, found that the risk of a heart attack or stroke was cut in half among those who took a statin. The study was stopped after two years, but some participants were tracked for up to five years. (Sources: Dr. Paul M. Ridker; New England Journal of Medicine) (pg.A21)
    A large new study suggests that millions more people could benefit from taking the cholesterol-lowering drugs known as statins, even if they have low cholesterol, because the drugs can significantly lower their risk of heart attacks, strokes and death.

    The study, involving nearly 18,000 people worldwide, tested statin treatment in men 50 and older and in women 60 and older who did not have high cholesterol or histories of heart disease. What they did have was high levels of a protein called high-sensitivity C-reactive protein, or CRP, which indicates inflammation in the body.

    Clinical Implications of JUPITER (Justification for the Use of statins in Prevention: an Intervention Trial Evaluating Rosuvastatin) in a U.S. Population
    Insights From the ARIC (Atherosclerosis Risk in Communities) Study
    Yang EY et al.
    J Am Coll Cardiol, 2009; 54:2388-2395,
    doi:10.1016/j.jacc.2009.10.006

    Conclusions: ARIC participants with elevated hs-CRP and low LDL-C had a CVD event rate of 1.57% per year over 6.9 years, similar to the CVD event rate noted in the JUPITER study placebo group (1.36% per year over 1.9 years). The association of hs-CRP ≥2.0 mg/l with increased CVD risk and mortality regardless of LDL-C provides us a simple method of using age and hs-CRP level for identifying higher risk individuals.

Patients With High CRP And Normal LDL Have Long-Term Risk For Heart Disease, Stroke And... - 0 views

  •  
    "New research shows a long-term benefit in screening people for CRP, a marker for inflammation, even if they have normal levels of bad cholesterol, because of increased long-term risk for heart attack, stroke and death.

    These findings, which will be published online today in the Journal of the American College of Cardiology (JACC), demonstrate that a very simple screening, age plus CRP, can identify individuals who may benefit from statin therapy.

    "This study builds on results from the landmark JUPITER trial, which showed that statins can prevent heart disease in people with normal LDL-c, or bad cholesterol, and an increased level of CRP," said Dr. Christie Ballantyne, director of the Center for Cardiovascular Disease Prevention at the Methodist DeBakey Heart & Vascular Center and last author on the study. "We have demonstrated that the cardiovascular disease event rates persist over time, validating that the risks identified in the JUPITER trial persist for nearly seven year"

NephroPal: Vitamin D - The saga goes on... - 0 views

    "Had enough about reading/hearing about Vitamin D? Well, it keeps on coming. And for my lack of surprise, the medical community in general is not catching on like wild fire. I really don't understand it.
    A recent study from the Heart Institute at Intermountain Medical Center in Salt Lake City (click) followed 27,686 patients greater than 50 years of age with no prior history of cardiovascular disease. The Vitamin D levels were checked and classified as such:

    * normal - greater than 30 ng/ml

    * low - 15 to 30

    * very low - less than 15

    The results of the study showed that patients with very low Vitamin D levels in comparison to normal had:

    * 77% greater risk of death

    * 45% increased risk of coronary artery disease

    * 78% increased risk of stroke

    * twice the risk of developing heart failure"

    Cardiovascular disease risk of dietary stearic acid compared with trans, other saturated, and unsaturated fatty acids: a systematic review1,3.
    Hunter JE, Zhang J, Kris-Etherton PM.
    Am J Clin Nutr. 2009 Nov 25. [Epub ahead of print]
    PMID: 19939984
    doi:10.3945/ajcn.2009.27661

    Conclusions: TFA intake should be reduced as much as possible because of its adverse effects on lipids and lipoproteins. The replacement of TFA with STA compared with other saturated fatty acids in foods that require solid fats beneficially affects LDL cholesterol, the primary target for CVD risk reduction; unsaturated fats are preferred for liquid fat applications. Research is needed to evaluate the effects of STA on emerging CVD risk markers such as fibrinogen and to understand the responses in different populations.

    Fish oil-derived fatty acids, docosahexaenoic acid and docosapentaenoic acid, and the risk of acute coronary events: the Kuopio ischaemic heart disease risk factor study.
    Rissanen T, Voutilainen S, Nyyssönen K, Lakka TA, Salonen JT.
    Circulation. 2000 Nov 28;102(22):2677-9.
    PMID: 11094031

    Methods and Results-We studied this association in the Kuopio Ischaemic Heart Disease Risk Factor Study, a prospective population study in Eastern Finland. Subjects were randomly selected and included 1871 men aged 42 to 60 years who had no clinical coronary heart disease at baseline examination. A total of 194 men had a fatal or nonfatal acute coronary event during follow-up. In a Cox proportional hazards' model adjusting for other risk factors, men in the highest fifth of the proportion of serum DHA+DPA in all fatty acids had a 44% reduced risk (P=0.014) of acute coronary events compared with men in the lowest fifth. Men in the highest fifth of DHA+DPA who had a low hair content of mercury (<=2.0 µg />2.0 µg/g). There was no association between proportion of eicosapentaenoic acid and the risk of acute coronary events.

    Conclusions-Our data provide further confirmation for the concept that fish oil-derived fatty acids reduce the risk of acute coronary events. However, a high mercury content in fish could attenuate this protective effect.

    N Engl J Med. 2002 Nov 28;347(22):1747-54.
    PMID: 12456850

    Conclusions The toenail mercury level was directly associated with the risk of myocardial infarction, and the adipose-tissue DHA level was inversely associated with the risk. High mercury content may diminish the cardioprotective effect of fish intake.

    High dietary methionine intake increases the risk of acute coronary events in middle-aged men.
    Virtanen JK, Voutilainen S, Rissanen TH, Happonen P, Mursu J, Laukkanen JA, Poulsen H, Lakka TA, Salonen JT.
    Nutr Metab Cardiovasc Dis. 2006 Mar;16(2):113-20. Epub 2005 Nov 2.
    PMID: 16487911
    doi:10.1016/j.numecd.2005.05.005

    Conclusions
    The main finding of this study is that long-term, moderately high dietary methionine intake may increase the risk of acute coronary events in middle-aged Finnish men free of prior CHD. More prospective research is needed to confirm the role of dietary methionine in the development of CVD, and whether its effects are independent of homocysteine.
