Abstract
Inflammation is part of the normal host response to infection and injury. However, inappropriate inflammation contributes to several diseases, including inflammatory bowel disease (IBD) and rheumatoid arthritis (RA). Both conditions are characterized by the excessive production of inflammatory cytokines, arachidonic acid (AA)-derived eicosanoids, and other inflammatory agents (e.g., reactive oxygen species, adhesion molecules). By virtue of their anti-inflammatory action, omega-3 polyunsaturated fatty acids (PUFA) may be beneficial in inflammatory diseases. A large body of evidence supports a protective effect of omega-3 PUFA in experimental animal and ex-vivo models of Crohn’s disease (CD), Ulcerative colitis (UC) and Rheumatoid arthritis (RA). Although fish oil supplementation in patients with IBD results in omega-3 PUFA incorporation into gut mucosal tissue and modification of inflammatory mediator profiles, the evidence of clinical benefits of omega-3 PUFA is weak. On the other hand, more convincing data support the efficacy of omega-3 PUFA in reducing pain, number of tender joints, duration of morning stiffness, use of non-steroidal anti-inflammatory drugs and improving physical performance in RA patients. In both IBD and RA further clinical trials with large sample size are needed to clarify the efficacy of omega-3 PUFA as a treatment.

Adiposity, cardiometabolic risk, and vitamin D status: the Framingham Heart Study.Cheng S, Massaro JM, Fox CS, Larson MG, Keyes MJ, McCabe EL, Robins SJ, O’Donnell CJ, Hoffmann U, Jacques PF, Booth SL, Vasan RS, Wolf M, Wang TJ. SourceFramingham Heart Study, Framingham, Massachusetts, USA. AbstractOBJECTIVE:Because vitamin D deficiency is associated with a variety of chronic diseases, understanding the characteristics that promote vitamin D deficiency in otherwise healthy adults could have important clinical implications. Few studies relating vitamin D deficiency to obesity have included direct measures of adiposity. Furthermore, the degree to which vitamin D is associated with metabolic traits after adjusting for adiposity measures is unclear. RESEARCH DESIGN AND METHODS:We investigated the relations of serum 25-hydroxyvitamin D (25[OH]D) concentrations with indexes of cardiometabolic risk in 3,890 nondiabetic individuals; 1,882 had subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT) volumes measured by multidetector computed tomography (CT). RESULTS:In multivariable-adjusted regression models, 25(OH)D was inversely associated with winter season, waist circumference, and serum insulin (P < 0.005 for all). In models further adjusted for CT measures, 25(OH)D was inversely related to SAT (-1.1 ng/ml per SD increment in SAT, P = 0.016) and VAT (-2.3 ng/ml per SD, P < 0.0001). The association of 25(OH)D with insulin resistance measures became nonsignificant after adjustment for VAT. Higher adiposity volumes were correlated with lower 25(OH)D across different categories of BMI, including in lean individuals (BMI <25 kg/m(2)). The prevalence of vitamin D deficiency (25[OH]D <20 ng/ml) was threefold higher in those with high SAT and high VAT than in those with low SAT and low VAT (P < 0.0001). CONCLUSIONS:Vitamin D status is strongly associated with variation in subcutaneous and especially visceral adiposity. The mechanisms by which adiposity promotes vitamin D deficiency warrant further study. Free PMC Article |

Abstract
BACKGROUND:
Studies suggest a link between vitamin D deficiency and development of asthma and allergic diseases.
AIM:
To determine a) the association between vitamin D and asthma among children, b) difference in level of vitamin D in asthmatic children and control, and c) effect of vitamin D on atopy markers.
SETTING:
Case-control study done, between October 2009 to July 2010, on asthmatics and controls (< 15 years) at Pediatric Allergy-Immunology Clinics and Primary Health care Clinics (PHC), Qatar. METHODS & SUBJECTS: A total of 483 cases and 483 controls matched by age, gender and ethnicity. Sociodemographic & clinical data was collected through physician diagnosis and questionnaire. Their health status was assessed by past or present clinical manifestations, family history, physical examination, BMI, and serum 25(OH) vitamin D, calcium, and phosphorus.
RESULTS:
44.8% of asthmatic and 50.0% of controls were males, and 55.2% of asthmatic and 50% of controls were females. The mean age (+/- SD, in years)for asthmatic versus controls was 7.0 +/- 3.8 vs. 8.4 +/- 3.6. Vitamin D deficiency was more prevalent in asthmatics than controls. The mean value of Vitamin D in asthmatics was much lower than the normal value, and there was a significant difference found in the mean values of vitamin D between asthmatics (17.5 +/- 11.0) and the controls (20.8 +/- 10.0). Furthermore, there were statistically significant differences between asthmatic subjects and controls with respect to serum level of vitamin D (p < 0.001). Lower Vitamin D levels were associated with more allergic disease and elevated serum IgE.
CONCLUSION:
Serum vitamin D levels were lower in asthmatic than control. Vitamin D deficiency was higher among children with asthma, allergic rhinitis, atopic dermatitis, acute urticaria, and food allergy. In addition, vitamin D deficiency was associated with IgE atopy markers in asthmatic children more than controls.
Women and Testosterone replacement (click here)
Wall Street Journal, March 15, 2009
By ERIKA SCHWARTZ , KENT HOLTORF , and DAVID BROWNSTEIN
Mainstream medicine has been given a wake-up call on a matter critical to the health of 65 million women in the U.S. At issue are the options for treatment of menopause symptoms that cause significant health problems for women in mid-life as their bodies produce fewer hormones. It doesn’t seem like a complicated problem, given advances in medical science. Yet hormone-replacement therapy has become a textbook example of how special interests, a confused medical establishment, and opportunists can combine to complicate the issue and deny patients access to safe and effective treatments.
Until seven years ago, women going to conventional doctors were prescribed the FDA-approved synthetic hormone Premarin, derived from the urine of pregnant horses; Provera, a synthetic progestin; or Prempro, a combination of the two. Premarin was the bestselling drug in the U.S. in 2001, generating $2 billion a year for Wyeth.
In 1994 a study led by the National Institutes of Health called the Women’s Health Initiative (WHI) was started with the hope of establishing that Premarin and Provera would, beyond relieving menopause symptoms, protect aging women from heart attacks, strokes, osteoporosis and cancer.
On July 9, 2002, however, the WHI came to an abrupt halt. The study proved unequivocally that the drugs were unsafe and significant factors in increasing the risk of heart attacks, strokes and breast cancer in the more than 16,000 women studied.
This led doctors to take millions of women off Premarin, Prempro and Provera overnight. Predictably, these women started to feel horrible in the aftermath of the drugs’ sudden withdrawal, and their physicians told them there were no alternatives. Instead they prescribed antidepressants or birth control pills with shoddy results.
One year after this disaster, the American College of Obstetrics and Gynecology developed new guidelines that encouraged physicians to prescribe the same drugs in lower doses for shorter periods of time. Yet, and this is key, the safety of this “low dose option” was never proven scientifically.
Meanwhile, many conventional physicians have ignored the effectiveness of “bioidentical” or natural progesterone, which is formulated to be identical to the progesterone molecule that is produced by the human body.
There are 25 years of scientific research with hundreds of studies in the U.S. and Europe that have demonstrated that bioidentical hormones, estradiol and micronized progesterone, are equally or more effective than synthetics — and safer. Yet mainstream medicine has buried its head in the sand and refused to take these studies seriously.
While Europeans have long used bioidenticals, no commercially available bioidentical hormones existed in the U.S. until 1998, when a few pharmaceutical companies obtained FDA approval for an array of bioidentical estrogen preparations and one progesterone preparation. Unfortunately, due to drug companies running the medical profession by controlling what goes into medical education, most doctors never get educated about bioidentical hormones or the way in which different hormone molecules work. With Premarin and Provera dominating the market, drug companies had no incentive to spread the word.
Today the distinction between bioidentical/natural progesterone and the synthetic progestin Provera remains widely misunderstood. Progesterone is used by fertility specialists to protect pregnancy, while medroxyprogesterone (Provera) is used in the morning after pill and in birth control pills to prevent pregnancy. Their actions are totally different and antithetical.
Sadly, seven years after the WHI study finding Premarin/Provera unsafe, the hormone-replacement debate can be summed up in three words: confusion, ignorance, misinformation. Meanwhile, millions of women have embraced bioidenticals, leaving their conventional physicians looking stubborn and foolish.
The medical establishment must stop kowtowing to drug companies and start serving women’s best interests — and that involves widely prescribing bioidentical hormones. This will lead to healthier, happier women and, in the long run, help reduce America ’s skyrocketing health-care costs.
