These observations suggest that VDR plays a critical role in mucosal barrier homeostasis by preserving the integrity of junction complexes and the healing capacity of the colonic epithelium. Therefore, vitamin D deficiency may compromise the mucosal barrier, leading to increased susceptibility to mucosal damage and increased risk of IBD.
Vitamin D and mood disorders among women: an integrative review.
Murphy PK, Wagner CL.
J Midwifery Womens Health. 2008 Sep-Oct;53(5):440-6. Review.
PMID: 18761297
Four of six studies reviewed imparted significant results, with all four showing an association between low 25(OH)D levels and higher incidences of four mood disorders: premenstrual syndrome, seasonal affective disorder, non-specified mood disorder, and major depressive disorder. This review indicates a possible biochemical mechanism occurring between vitamin D and mood disorders affecting women, warranting further studies of these variables using rigorous methodologies.
The American diet circa 2007 is a disaster - but positive change has begun. Those were the twin themes of the "Fourth Annual Nutrition and Health Conference" held in San Diego, Calif., May 14-16, 2007. The conference was sponsored by the University of Arizona's College of Medicine in conjunction with the Program in Integrative Medicine (PIM); PIM was founded and is co-directed by Dr. Weil. \n\nThe three-day event brought together leading nutrition researchers from around the world, bearing plenty of both bad and good news. Some highlights:
Hypovitaminosis D in an Italian population of healthy subjects and hospitalized patients.

The results of the present study emphasize the importance of 25-hydroxyvitamin D measurement, and the need to increase vitamin D intake in Italy; foodstuff fortification and supplement use must be considered in order to prevent negative effects of vitamin D deficiency on skeletal integrity.
All hospitalized patients, both in summer and in winter,
are characterized by the highest prevalence of hypovitaminosis
D, especially the older patients. Medical
inpatients may be at risk for vitamin D deficiency,
