BACKGROUND: Vitamin D is an environmental and dietary agent with known anticarcinogenic effects, but protection against breast cancer has not been established. OBJECTIVE: We evaluated the association between baseline serum 25-hydroxyvitamin D [25(OH)D] levels, supplemental vitamin D use, and breast cancer incidence over the subsequent 5 y of follow-up. METHODS: From 2003-2009, the Sister Study enrolled 50,884 U.S. women 35-74 y old who had a sister with breast cancer but had never had breast cancer themselves...

Patients with exocrine pancreatic insufficiency (EPI) have suboptimal secretion of pancreatic digestive enzymes and experience a range of clinical symptoms related to the malabsorption of fat. In patients with EPI unable to meet their nutritional requirements, enteral nutrition (EN) support is used to augment nutritional status. In addition to protein and carbohydrate, EN formulas contain fats as a calorie source, as well as vitamins and minerals to help prevent nutritional deficiencies related to malabsorption...

Denosumab is a very effective treatment of osteoporosis, easy to use and very well tolerated. Due to some associated risks, a close clinical follow-up is necessary. Before the first injection, it is necessary to correct hypocalcaemia or vitamin D deficiency when present. Calcemia has to be followed in case of renal insufficiency. Injections of denosumab should be done scrupulously every 6 months (± 3 weeks). Discontinuation of denosumab is associated with a severe rebound effect characterized by increased markers of bone remodeling, a rapid decrease of bone density values, and a risk of multiple spontaneous vertebral fractures...

Low fat mass is associated with an increased risk of fracture because of low bone mineral density (BMD) and altered bone micro-architecture. Conversely, overweight and obese patients also have an increased risk of fracture, particularly of the humerus and ankle, despite greater BMD. Visceral abdominal fat, which is the most metabolically active, may be associated with poorer quality of bone tissue properties, as suggested in diabetes. Other factors may contribute to higher fracture risk in overweight patients, notably higher frequency of falls and lower bioavailability of vitamin D stoked in fat...

How to recognize secondary causes of bone fragility in relation with an abnormal calcium and phosphate laboratory in general practice ? Through clinical cases presentations we will discuss the calcium and phosphate abnormalities which can be related to bone fragility and for which a-specific approach must be proposed. It can be abnormal results of calcium, phosphate or vitamin D. Some causes are frequent, others are iatrogenic, and others are related to a rare disease sometimes of genetic cause which consequences are more important than expected...

This study was conducted to determine whether circulating concentrations of blood isoprostanes can be used as an effective biomarker in lambs to predict degradation of color and/or lipid stability in meat. Lambs ( = 84) were fed diets of either lucerne pasture, annual ryegrass pasture, a commercial feedlot pellet, or a combination of annual ryegrass and feedlot pellet for 8 wk, including a 2-wk adaptation period. Blood isoprostane concentration at wk 0, 4, 6 or 8 of feeding was determined. Blood isoprostane concentration for each animal was then correlated with muscle biochemical components that impact color and/or lipid oxidative status during retail display...

Nutritional and genetic strategies are needed to enhance intramuscular fat (IMF) and MUFA content without altering carcass leanness. Dietary vitamin A restriction has been suggested to specifically promote IMF, whereas a polymorphism of the () gene has shown to specifically increase MUFA. The purpose of this study was to investigate the combined effects of provitamin A (PVA) carotenoid intake and genotype (>) on hepatic retinoid content and on the liver, muscle (LM and gluteus medius [GM]), and subcutaneous fat (SF) content and fatty acid composition...

Age-related macular degeneration (AMD) ranks third among the leading causes of visual impairment with a blindness prevalence rate of 8.7%. Despite several treatment regimens, such as anti-angiogenic drugs, laser therapy, and vitamin supplementation, being available for wet AMD, to date there are no FDA-approved therapies for dry AMD. Substantial evidence implicates mitochondrial damage and retinal pigment epithelium (RPE) cell death in the pathogenesis of AMD. However, the effects of AMD mitochondria and Humanin G (HNG), a more potent variant of the mitochondrial-derived peptide (MDP) Humanin, on retinal cell survival have not been elucidated...

Sjögren's syndrome (SS) is a chronic autoimmune inflammatory disease that typically affects the salivary and lacrimal glands. Renal involvement is relatively uncommon and may precede other complaints. Tubulointestitial nephritis (TIN) is the most common renal involvement in SS. Osteomalacia occurring as the first manifestation of renal tubular disorder due to SS is very rare. We report a 39-year-old male who presented with polydipsia, polyuria, and multiple bone pain. Bone density test showed severe osteoporosis, and laboratory findings suggested hypokalemia, hypophosphatemia, and vitamin D deficiency, which supported the diagnosis of hypophosphatemic osteomalacia...

Cytomegalovirus (CMV) infection in small intestines has rarely been reported. We report a 67-year-old woman with abdominal pain for 2 weeks. Abdominal computed tomography (CT) revealed wall-thickening of the segmental small bowel. Enteroscopy disclosed discrete ulcers at the jejunum, and biopsy histopathology showed positive CMV immunoreactivity. Laboratory tests showed positive blood CMV with a viral load of 9,400 DNA copies/mL and high IgG titer and low vitamin D level. After antiviral therapy and oral vitamin D supply, her symptoms improved...

INTRODUCTION    Massive consumption of dietary supplements, including vitamins and minerals, has recently became a serious public issue in Europe. When ingested, they may negatively affect pharmacological activity of various medications, including anti-allergic drugs. Calcium preparations are well-known and commonly used in some European countries as a popular remedy for allergy-related skin reactions, such as itching, erythema and wheals, as well as insect bites. However, their action has not been reliably proven yet...
