    25(OH)D Serum levels decline with age earlier in women than in men and less efficiently prevent compensatory hyperparathyroidism in older adults. Maggio D, Cherubini A, Lauretani F, Russo RC, Bartali B, Pierandrei M, Ruggiero C, Macchiarulo MC, Giorgino R, Minisola S, Ferrucci L. J Gerontol A Biol Sci Med Sci. 2005 Nov;60(11):1414-9. PMID: 16339327 Conclusions. These findings suggest that the age-associated fall of serum 25(OH)D starts earlier in women than in men and that higher levels of 25(OH)D are required in older compared to younger persons to avoid the age-associated compensatory hyperparathyroidism.

    Depression may be triggered by low vitamin D levels in the blood, according to a new study published in the Aug 19, 2009 issue of European Journal of Clinical Nutrition. The study led by Nanri A and colleagues from International Medical center of Japan in Shinjuku-ku, Tokyo, Japan found that in November, people with their serum levels of vitamin D falling in the highest quartile were 49 percent less likely to feel depressed. The study involved 527 municipal employees aged 21 to 67 who worked in two municipal offices in Japan. It was meant to examine the association between vitamin D deficiency and depression

PMID: 7872586 CONCLUSIONS: Although the patients had normal or near-normal total 1,25-(OH)2D values, most patients had elevated free 1,25-(OH)2D levels. These findings suggest that elevated free 1,25-(OH)2D levels might play a role in the pathogenesis of hypercalcemia in vitamin D toxicity.

Cancer Res. 2006 Oct 15;66(20):10213-9. PMID: 17047087 doi: 10.1158/0008-5472.CAN-06-1876 Contrary to expectations, subjects with higher prediagnostic vitamin D status had an increased pancreatic cancer risk compared with those with lower status. Our findings need to be replicated in other populations and caution is warranted in their interpretation and implication. Our results are intriguing and may provide clues that further the understanding of the etiology of this highly fatal cancer.
