Serum vitamin D and subsequent occurrence of type 2 diabetes. Knekt P, Laaksonen M, Mattila C, Härkänen T, Marniemi J, Heliövaara M, Rissanen H, Montonen J, Reunanen A. Epidemiology. 2008 Sep;19(5):666-71. PMID: 18496468 doi: 10.1097/EDE.0b013e318176b8ad Conclusions: The results support the hypothesis that high vitamin D status provides protection against type 2 diabetes. Residual confounding may contribute to this association.

SSeason of diagnosis is a prognostic factor in Hodgkin's lymphoma: a possible role of sun-induced vitamin D. Porojnicu AC, Robsahm TE, Ree AH, Moan J. Br J Cancer. 2005 Sep 5;93(5):571-4. PMID: 16136030 doi:10.1038/sj.bjc.6602722 Epidemiological data for this period indicate that season of diagnosis is a strong prognostic factor for Hodgkin's lymphoma, with approximately 20% lower case fatality for patients diagnosed during autumn vs winter diagnosis (RR = 0.783, 95% CI,-0.62 to 0.99; P = 0.041). Notably, the improved autumnal survival rate was higher than 60% (RR = 0.364, 95% CI, -0.15 to 0.87; P = 0.025) for patients younger than 30 years. This finding may be related to higher endogenous levels of vitamin D in autumn, with a favourable influence on the conventional therapy. In conclusion, we have found that the prognosis of Hodgkin's lymphoma is significantly correlated with the season of diagnosis, particularly for patients younger than 30 years. This seasonal effect is presumably due to the vitamin D3 synthesis in skin during sun exposure. The present findings should encourage further investigations of the possible adjuvant role of vitamin D derivatives in cancer therapy

Low vitamin d levels predict stroke in patients referred to coronary angiography. Pilz S, Dobnig H, Fischer JE, Wellnitz B, Seelhorst U, Boehm BO, März W. Stroke. 2008 Sep;39(9):2611-3. Epub 2008 Jul 17. PMID: 18635847 doi: 10.1161/STROKEAHA.107.513655 Conclusions- Low levels of 25(OH)D and 1,25(OH)2D are independently predictive for fatal strokes, suggesting that vitamin D supplementation is a promising approach in the prevention of strokes.

Prospective study of predictors of vitamin D status and cancer incidence and mortality in men. Giovannucci E, Liu Y, Rimm EB, Hollis BW, Fuchs CS, Stampfer MJ, Willett WC. J Natl Cancer Inst. 2006 Apr 5;98(7):451-9. PMID: 16595781 doi:10.1093/jnci/djj101 Conclusions: Low levels of vitamin D may be associated with increased cancer incidence and mortality in men, particularly for digestive-system cancers. The vitamin D supplementation necessary to achieve a 25(OH)D increment of 25 nmol/L may be at least 1500 IU/day.

Calcium and vitamin d supplementation decreases incidence of stress fractures in female navy recruits. Lappe J, Cullen D, Haynatzki G, Recker R, Ahlf R, Thompson K. J Bone Miner Res. 2008 May;23(5):741-9. PMID: 18433305 doi: 10.1359/jbmr.080102 Conclusions: Generalizing the findings to the population of 14,416 women who entered basic training at the Great Lakes during the 24 mo of recruitment, calcium and vitamin D supplementation for the entire cohort would have prevented 187 persons from fracturing. Such a decrease in SFx would be associated with a significant decrease in morbidity and financial costs.

1,25(OH)2 vitamin d inhibits foam cell formation and suppresses macrophage cholesterol uptake in patients with type 2 diabetes mellitus. Oh J, Weng S, Felton SK, Bhandare S, Riek A, Butler B, Proctor BM, Petty M, Chen Z, Schechtman KB, Bernal-Mizrachi L, Bernal-Mizrachi C. Circulation. 2009 Aug 25;120(8):687-98. Epub 2009 Aug 10. PMID: 19667238 doi: 10.1161/CIRCULATIONAHA.109.856070 Conclusion- These results identify reduced vitamin D receptor signaling as a potential mechanism underlying increased foam cell formation and accelerated cardiovascular disease in diabetic subjects.

Vitamin D, nervous system and aging. Tuohimaa P, Keisala T, Minasyan A, Cachat J, Kalueff A. Psychoneuroendocrinology. 2009 Aug 4. [Epub ahead of print] PMID: 19660871

Ecological studies of ultraviolet B, vitamin D and cancer since 2000. Grant WB, Mohr SB. Ann Epidemiol. 2009 Jul;19(7):446-54. Epub 2009 Mar 9. PMID: 19269856 CONCLUSION: These findings provide strong evidence that vitamin D status plays an important role in controlling the outcome of cancer. Support for the UVB-vitamin D-cancer theory is now scientifically strong enough to warrant use of vitamin D in cancer prevention, and as a component of treatment. More research studies would help to explore whether there are benefits beyond the substantial effects that have been observed.

Meta-analysis of vitamin D, calcium and the prevention of breast cancer. Chen P, Hu P, Xie D, Qin Y, Wang F, Wang H. Breast Cancer Res Treat. 2009 Oct 23. [Epub ahead of print] PMID: 19851861 These results provide strong evidence that vitamin D and calcium have a chemopreventive effect against breast cancer.
