Both vitamin D deficiency and cognitive impairment are common in patients with chronic kidney disease (CKD). Vitamin D exerts neuroprotective and regulatory roles in the central nervous system. Hypovitaminosis D has been associated with muscle weakness and bone loss, cardiovascular diseases (hypertension, diabetes and hyperlipidemia), inflammation, oxidative stress, immune suppression and neuro...

BACKGROUND As vitamin D may have a neuroprotective effect, the authors studied the association of biomarkers of vitamin D status and delirium to see if low vitamin D status was common in delirium cases. METHODS Biochemical measures of vitamin D (25-hydroxyvitamin D [25-OHD]) and calcium metabolism were used in this retrospective cross-sectional analysis of adult in-patients with delirium, adm...

AIM To determine the prevalence of vitamin D hypovitaminosis among obese and overweight schoolchildren. DESIGN A cross-sectional population based sample.

Inadequate vitamin D level is associated with various adverse medical outcomes. There is a growing concern that insufficient vitamin D may play a role in the development of psychiatric symptoms. This study aims to answer the question: do children with mental disorders have a higher prevalence of hypovitaminosis D?

BACKGROUND Little is known regarding vitamin D deficiency (VDD) in African populations and in tuberculosis (TB) patients. VDD has been shown to be associated with TB. OBJECTIVE We aimed to compare the degree of vitamin D insufficiency (VDI) and VDD in TB patients and healthy adult controls in a West African population. DESIGN An unmatched case-control study was performed at a Demographic Su...

BACKGROUND Hypovitaminosis D is linked to unstable health in older adults. Our objectives were to determine (i) the difference in length of stay (LOS) in geriatric acute care unit between inpatients with and without hypovitaminosis D and (ii) whether there was a linear association between serum 25-hydroxyvitamin D (25OHD) concentration and LOS. METHODS 253 inpatients admitted in 2008 to the g...
