BACKGROUND: Hepatic osteodystrophy caused by vitamin D and calcium malabsorption is thought to develop in children with cholestatic liver disease leading to secondary hyperparathyroidism and rickets or osteomalacia. The aim of this study was to evaluate the dental and bone mineral densities and the serum level of vitamin D in cholestatic infants and children and to correlate this process with clinical and laboratory parameters. METHODS: This is a cross-sectional study that include 50 patients presenting with cholestasis...

Dietary supplements such as vitamins and minerals are widely used in the hope of improving health but may have unidentified risks and side effects. In particular, a pathogenic link between dietary supplements and specific oncogenes remains unknown. Here we report that chondroitin-4-sulfate (CHSA), a natural glycosaminoglycan approved as a dietary supplement used for osteoarthritis, selectively promotes the tumor growth potential of BRAF V600E-expressing human melanoma cells in patient- and cell line-derived xenograft mice and confers resistance to BRAF inhibitors...

Secondary hyperparathyroidism (SHPT) is one of the most frequent and deleterious complication of chronic kidney disease (CKD). SHPT is also one of the principal components of the now called CKD-mineral and bone disorders (MBD) syndrome. It is usually prevented and treated by vitamin D derivatives. However, the rationale for the prescription of vitamin D sterols in those patients is still a matter of hotly debates, mainly because of unsatisfactory results from numerous observational and not well-controlled studies...

Appropriate intake of micronutrient, such as electrolyte minerals is critical for the well-being of the cardiovascular health system. However, there are some debates regarding the impacts of dietary and/or supplemental intake of these minerals, on the risk of cardiovascular events and associated risk factors. High sodium intake is adversely associated with the risk of hypertension. Although many reports refered to the positive association of Na intake and cardiovascular events and all-cause mortality, however, other studies indicated that low Na intake is related to higher risk of all-cause mortality and HF-related events...

Background: In the past two decades, Vitamin K has been receiving more attention due to its role in bone health and metabolism. The bone mineral density does not remain steady with age, particularly declining after menopause. Objective: This study is aimed to investigate the relationship between bone mineral density and serum vitamin K1 levels in post-menopausal women, and to evaluate serum vitamin K1 levels as a potential biomarker for postmenopausal osteoporosis...

INTRODUCTION: The ketogenic diet is a non-pharmacological treatment that has been used as a therapeutic alternative for the management of refractory epilepsy since 1921. It is a diet, high in fats and low in carbohydrates, which is used to treat paediatric refractory epilepsy, and is effective in around 50% of the patients that begin to follow it. It is a nutrition plan that is imbalanced in terms of both macro- and micro-nutrients, which can give rise to nutritional deficits in energy, proteins, minerals and vitamins, as well as an excess of lipids...

Purpose: The purpose of this study was to evaluate the effects of 1,25-dihydroxyvitamin D3 on the proliferation, differentiation, and matrix mineralization of MC3T3-E1 osteoblast-like cells in vitro. Methods: MC3T3-E1 osteoblastic cells and 1,25-dihydroxyvitamin D3 were prepared. Cytotoxic effects and osteogenic differentiation were evaluated using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, alkaline phosphatase (ALP) activity assay, ALP staining, alizarin red S staining, and reverse transcription-polymerase chain reaction (RT-PCR) for osteogenic differentiation markers such as ALP, collagen type I (Col-I), osteocalcin (OCN), vitamin D receptor (VDR), and glyceraldehyde 3-phosphate dehydrogenase...

Moringa oleifera Lam. ( M. oleifera ), which belongs to the Moringaceae family, is a perennial deciduous tropical tree, and native to the south of the Himalayan Mountains in northern India. M. oleifera is rich in proteins, vitamin A, minerals, essential amino acids, antioxidants, and flavonoids, as well as isothiocyanates. The extracts from M. oleifera exhibit multiple nutraceutical or pharmacological functions including anti-inflammatory, antioxidant, anti-cancer, hepatoprotective, neuroprotective, hypoglycemic, and blood lipid-reducing functions...

Surveys indicated that 24% of military personnel are current cigarette smokers. Smoking is well known to increase the risk of cancers, cardiovascular and respiratory diseases, reproductive problems, and other medical maladies, but one of the little known effects of smoking is that on injuries. There is considerable evidence from a variety of sources that (1) smoking increases overall injury risk, (2) the greater the amount of smoking, the higher is the injury risk, and (3) smoking is an independent injury risk factor...

We evaluated the vitamin D receptor (VDR) expression in the forearm flexor muscle of women with distal radius fracture. High VDR expression was associated with low appendicular lean mass index. INTRODUCTION: We aimed to evaluate the relationship between the VDR expression in the muscle cell and the muscle mass in women with a distal radius fracture (DRF). METHODS: We prospectively recruited 45 women over 50 years of age (mean age, 66 years) with DRF and acquired biopsy of the forearm flexor muscle...

BACKGROUND & AIMS: Vitamin D is a pleiotropic hormone targeting several tissues and is involved in basic homeostatic processes, including bone mineralization, immune response and muscle strength. Although hypovitaminosis D is common in Europe and North America, representing a risk factor for several chronic diseases, the contribution of factors other than sun exposure is largely underestimated. METHODS: In our study, we retrospectively collected data from medical records of women with age between 19 and 80 screened in Central Italy (42°N) for increased risk of metabolic syndrome...

OBJECTIVES: Sleep difficulties are a serious health problem in children, and interest in using complementary and alternative medicine (CAM) therapies to treat sleep is growing. In this study, we aimed to identify: the prevalence of sleep difficulties in children, and the prevalence and patterns of CAM use among children with trouble sleeping. METHODS: We used the 2012 National Health Interview Survey (NHIS) dataset to estimate the prevalence of sleep difficulties and CAM use in children ages 6-17 years...

Inflammatory bowel disease (IBD), including ulcerative colitis and Crohn's disease, is a chronic and unpredictable characterized by alternating periods of remission interspersed with relapses. In recent years accumulating support for an immunomodulating effect of vitamin D on both the innate and adaptive immune system has been presented. Through the vitamin D receptor, the active form of vitamin D, 1,25(OH)2D, induces antimicrobial peptide secretion, decrease dendritic cell activity, and promotes Th2 and regulatory T cell development and activity...
