Epidemiologic evidence on the association between vitamin D and breast cancer is still inconclusive. This study analyzes the association between serum 25-hydroxyvitamin D (25(OH)D) and breast cancer risk by pathologic subtype, stage at diagnosis and specific breast cancer risk factors. We conducted a population-based multicase-control study where 546 histologically-confirmed breast cancer cases and 558 population controls, frequently matched by geographic area, age and body mass index, were recruited in 12 Spanish provinces (MCC-Spain)...

AIM: Irisin is a new peptide produced mainly by the skeletal muscle playing an important role both in glucose/energy homeostasis and bone metabolism. Childhood type 1 diabetes mellitus (T1DM) is associated with decreased bone mass. We aimed to evaluate irisin levels in TD1M children and their correlation with bone metabolism and glycaemic control. METHODS: Ninety-six T1DM subjects (12.2 ± 4 years), 56 on multiple daily injections (MDI), 40 on continuous subcutaneous insulin infusion (CSII), and 34 controls were included in the study...

Burosumab (Crysvita® ; Kyowa Hakko Kirin Co., Ltd. and Ultragenyx Pharmaceutical Inc.) is a fully human monoclonal antibody directed at fibroblast growth factor 23 (FGF23). Excessive FGF23 production has been implicated in various hypophosphataemic diseases. Inhibition of FGF23 by burosumab results in increased renal phosphate reabsorption and increased serum levels of phosphorus and active vitamin D. In February 2018, the EMA granted subcutaneous burosumab conditional marketing authorization for the treatment of X-linked hypophosphataemia (XLH) with radiographic evidence of bone disease in children one year of age and older and adolescents with growing skeletons...

The number of patients with atrial fibrillation undergoing percutaneous coronary intervention (PCI) is increasing. Since these patients have a CHA2 DS2 -VASc score of 1 or higher, they should be treated with oral anticoagulation to prevent stroke. However, combination therapy with oral anticoagulation for prevention of embolic stroke and dual platelet inhibition for prevention of coronary thrombosis significantly increases bleeding complications. The optimal combination, intensity and duration of antithrombotic combination therapy is still not known...

Optimizing bone mass in adulthood is of great importance to prevent the occurrence of osteoporosis in later age. Vitamin D is an essential component of bone health. Low-serum vitamin D is associated with low bone mineral density (BMD), which is an important predictor of fracture risk. However, most cells, apart from renal tubular cells, are exposed to free rather than to total 25-hydroxyvitamin D. Whether free vitamin D would be a better marker than total vitamin D is still under debate. The aim of the present study was to explore the relationships between serum total vitamin D, vitamin D-binding protein (BP), free vitamin D, and bone parameters in a group of young Lebanese women...

OBJECTIVE: Effects of long-term imprisonment on the vitamin D (vitD) status of prison inmates in Germany have not been systematically assessed so far. Special circumstances in prisons - little sunlight exposure combined with restricted outdoor activities - may lead to vitD deficiency among prisoners. The aim of this study was to assess the vitD status of prisoners and the general population in order to quantify the extent of vitD deficiency in both groups. METHODS: VitD status (25(OH)D in blood serum samples) was assessed in female inmates of a prison in southern Germany between May 2012-June 2013...

Fibromyalgia (FM) is a complex chronic condition of unknown etiology, characterized by deep and widespread pain, sleep problems, cognitive impairment, fatigue, and other well-known functional symptoms. Recently, it has been proposed that an imbalance of nutritive components, including essential metal ions and vitamins, might play a critical role in the development of FM. Muscle pain has been associated with deficiencies in amino acids, magnesium, selenium, vitamins B and D, as well as with the harmful effects of heavy metals, such as mercury, cadmium, and lead...

Importance: Because of the aging population, osteoporotic fractures are an increasingly important cause of morbidity and mortality in the United States. Approximately 2 million osteoporotic fractures occurred in the United States in 2005, and annual incidence is projected to increase to more than 3 million fractures by 2025. Within 1 year of experiencing a hip fracture, many patients are unable to walk independently, more than half require assistance with activities of daily living, and 20% to 30% of patients will die...

PURPOSE OF REVIEW: Treatment of mineral metabolism is a mainstay of dialysis care including some of its most widely used and costly pharmaceuticals. Although many mineral metabolites are associated with increased risk of mortality, cardiovascular disease, and other morbidities, few clinical trials are available to guide therapy and most focus on single drug approaches. In practice, providers manage many aspects of mineral metabolism simultaneously in integrated treatment approaches that incorporate multiple agents and changes in the dialysis prescription...

Polycystic ovary syndrome (PCOS) is an endocrine and metabolic disorder in reproductive-aged women. Hormonal abnormality caused by steroidogenesis disturbances appears to be the main culprit of the clinical picture in PCOS. Vitamin D3 could regulate steroidogenesis in granulosa cells, but the mechanism of action of vitamin D3 on steroidogenesis remains unknown. AMP-activated protein kinase (AMPK) has a modulating role in steroid hormone production. We investigated the effect of vitamin D3 on steroidogenesis in cultured granulosa cells of dehydroepiandrosterone-induced PCOS mice and studied the involvement of AMPK signalling pathway in the current process...
