In the following study, we mainly investigate the effects of static magnetic field (SMF) (128 mT, 1 hr/day during 5 consecutive days) on 25-hydroxyvitamin D3 and calcium homeostasis. Wistar male rats, weighing 50-70 g, were randomly divided into four experimental groups: control, SMF-exposed rat, co-exposed rats (the last day and after exposure rats received a single dose of vitamin D per os) a...

The epidemiological profile of the HIV virus has undergone substantial modifications with advances in antiretroviral therapy. There has been a sharp decline in morbi-mortality levels of HIV-infected patients, which has resulted in higher survival rates. The HIV seropositive population is living longer and more exposed to chronic complications caused by the disease itself and the prolonged use o...

Vitamin D deficiency is nowadays very common in the general population and also in patients with primary hyperparathyroidism. Hypovitaminosis D may modify the clinical features and the severity of primary hyperparathyroidism. We present the case of a 75-year-old woman with a 10 year history of nephrolithiasis and severe osteoporosis, with multiple fragility fractures. Her bone and kidney status...

OBJECTIVE to assess whether 25hydroxivitaminD or 25(OH)vitD deficiency has a high prevalence at pediatric intensive care unit (PICU) admission, and whether it is associated with increased prediction of mortality risk scores. METHOD prospective observational study comparing 25(OH)vitD levels measured in 156 patients during the 12 hours after critical care admission with the 25(OH)vitD levels o...

BACKGROUND Vitamin D deficiency is prevalent in India, a finding that is unexpected in a tropical country with abundant sunshine. Vitamin D deficiency during pregnancy has important implications for the newborn and infant. There are few data from India about the prevalence of hypovitaminosis D in pregnancy and in the newborn. OBJECTIVE Our aim was to determine the prevalence of osteomalacia a...

O’Brien et al [1] found that obesity was a risk factor for severe influenza infection in mice and proposed poor lung wound healing, leading to pulmonary edema suggestive of acute respiratory distress syndrome, as a potential underlying mechanism, rather than a lack of viral control. They suggested that obesity should be recognized as a risk factor requiring early antiviral therapy [1]. However,...

Hypovitaminosis D is associated with impaired neuromuscular function, bone loss, and fractures. If a person is not taking a vitamin supplement, sun exposure is often the greatest source of vitamin D. Thus, vitamin D deficiency is not uncommon in the winter, particularly in northern latitudes. Our goal was to establish the prevalence of vitamin D deficiency in south Florida (U.S.), a region of y...

Hypovitaminosis D has been identified as a possible new cardiovascular risk factor. However, the results of studies correlating serum vitamin D levels with markers of subclinical atherosclerosis have been conflicting. The aim of this study was to correlate serum levels of 25-hydroxyvitamin D [25(OH)D] with carotid intima-media thickness (C-IMT) and conventional cardiovascular risk factors in Af...

Introduction: Optimal serum levels of vitamin D are great importance, especially in populations with comorbidities such as Diabetes Mellitus (DM). Objective: The study evaluated the relationship between hypovitaminosis and glycemic control older adults type 2 DM. Methods: Cross-sectional prospective study, part EELO project (Study on Aging Longevity), conducted Southern Brazil. Glycated hemoglo...
