Vitamin D from dietary intake and sunlight exposure and the risk of hormone-receptor-defined breast cancer. Blackmore KM, Lesosky M, Barnett H, Raboud JM, Vieth R, Knight JA. Am J Epidemiol. 2008 Oct 15;168(8):915-24. Epub 2008 Aug 27. PMID: 18756015 doi:10.1093/aje/kwn198 This study suggests that vitamin D is associated with a reduced risk of breast cancer regardless of ER/PR status of the tumor. Future studies with a larger number of receptor-negative and mixed tumors are required.

Vitamin D Status and the Risk of Cardiovascular Disease Death. Kilkkinen A, Knekt P, Aro A, Rissanen H, Marniemi J, Heliövaara M, Impivaara O, Reunanen A. Am J Epidemiol. 2009 Sep 17. [Epub ahead of print] PMID: 19762371 doi:10.1093/aje/kwp227 A low vitamin D level may be associated with higher risk of a fatal CVD event, particularly cerebrovascular death. These findings need to be replicated in other populations. To demonstrate a causal link between vitamin D and CVD, randomized controlled trials are required.

Serum Vitamin D and Risk of Prostate Cancer in a Case-Control Analysis Nested Within the European Prospective Investigation into Cancer and Nutrition (EPIC). Travis RC, Crowe FL, Allen NE, Appleby PN, Roddam AW, Tjønneland A, Olsen A, Linseisen J, Kaaks R, Boeing H, Kröger J, Trichopoulou A, Dilis V, Trichopoulos D, Vineis P, Palli D, Tumino R, Sieri S, Bueno-de-Mesquita HB, van Duijnhoven FJ, Chirlaque MD, Barricarte A, Larrañaga N, González CA, Argüelles MV, Sánchez MJ, Stattin P, Hallmans G, Khaw KT, Bingham S, Rinaldi S, Slimani N, Jenab M, Riboli E, Key TJ.

Hypovitaminosis D among rheumatology outpatients in clinical practice.\nMouyis M, Ostor AJ, Crisp AJ, Ginawi A, Halsall DJ, Shenker N, Poole KE.\nRheumatology (Oxford). 2008 Sep;47(9):1348-51. Epub 2008 May 22.\nPMID: 18499714 \ndoi:10.1093/rheumatology/ken203

Fish, vitamin D, and flavonoids in relation to renal cell cancer among smokers. Wilson RT, Wang J, Chinchilli V, Richie JP, Virtamo J, Moore LE, Albanes D. Am J Epidemiol. 2009 Sep 15;170(6):717-29. Epub 2009 Aug 3. PMID: 19651663 doi:10.1093/aje/kwp178 These results suggest that the flavonoid quercetin may prevent renal cell cancer among male smokers. The possible risk associated with fish intake warrants further investigation before conclusions may be drawn.

Vitamin D status predicts physical performance and its decline in older persons. Wicherts IS, van Schoor NM, Boeke AJ, Visser M, Deeg DJ, Smit J, Knol DL, Lips P. J Clin Endocrinol Metab. 2007 Jun;92(6):2058-65. Epub 2007 Mar 6. PMID: 17341569 doi:10.1210/jc.2006-1525 ONCLUSIONS: Serum 25-OHD concentrations below 20 ng/ml are associated with poorer physical performance and a greater decline in physical performance in older men and women. Because almost 50% of the population had serum 25-OHD below 20 ng/ml, public health strategies should be aimed at this group.

Estimation of the dietary requirement for vitamin D in free-living adults >=64 y of age. Cashman KD, Wallace JM, Horigan G, Hill TR, Barnes MS, Lucey AJ, Bonham MP, Taylor N, Duffy EM, Seamans K, Muldowney S, Fitzgerald AP, Flynn A, Strain JJ, Kiely M. Am J Clin Nutr. 2009 May;89(5):1366-74. Epub 2009 Mar 18. PMID: 19297462 doi:10.3945/ajcn.2008.27334 Conclusion: To ensure that the vitamin D requirement is met by the vast majority (>97.5%) of adults aged ≥64 y during winter, between 7.9 and 42.8 µg vitamin D/d is required, depending on summer sun exposure and the threshold of adequacy of 25(OH)D. .

Estimation of the dietary requirement for vitamin D in healthy adults.\nCashman KD, Hill TR, Lucey AJ, Taylor N, Seamans KM, Muldowney S, Fitzgerald AP, Flynn A, Barnes MS, Horigan G, Bonham MP, Duffy EM, Strain JJ, Wallace JM, Kiely M.\nAm J Clin Nutr. 2008 Dec;88(6):1535-42.\nPMID: 19064513 [

Serum vitamin D and risk of prostate cancer in a case-control analysis nested within the European Prospective Investigation into Cancer and Nutrition (EPIC). Travis RC, Crowe FL, Allen NE, Appleby PN, Roddam AW, Tjønneland A, Olsen A, Linseisen J, Kaaks R, Boeing H, Kröger J, Trichopoulou A, Dilis V, Trichopoulos D, Vineis P, Palli D, Tumino R, Sieri S, Bueno-de-Mesquita HB, van Duijnhoven FJ, Chirlaque MD, Barricarte A, Larrañaga N, González CA, Argüelles MV, Sánchez MJ, Stattin P, Hallmans G, Khaw KT, Bingham S, Rinaldi S, Slimani N, Jenab M, Riboli E, Key TJ. Am J Epidemiol. 2009 May 15;169(10):1223-32. Epub 2009 Apr 9. PMID: 19359375 In summary, the results of this large nested case-control study provide no evidence in support of a protective effect of circulating concentrations of vitamin D on the risk of prostate cancer.

Association between 25-hydroxyvitamin D levels and cognitive performance in middle-aged and older European men. Lee DM, Tajar A, Ulubaev A, Pendleton N, O'Neill TW, O'Connor DB, Bartfai G, Boonen S, Bouillon R, Casanueva FF, Finn JD, Forti G, Giwercman A, Han TS, Huhtaniemi IT, Kula K, Lean ME, Punab M, Silman AJ, Vanderschueren D, Wu FC; EMAS study group. J Neurol Neurosurg Psychiatry. 2009 Jul;80(7):722-9. Epub 2009 May 21. PMID: 19460797 doi:10.1136/jnnp.2008.165720 Conclusion: In this study, lower 25(OH)D levels were associated with poorer performance on the DSST. Further research is warranted to determine whether vitamin D sufficiency might have a role in preserving cognitive function in older adults.
