Myasthenia gravis (MG) patients had low proximal hip BMD, which could be explained by reduced muscle strength, elevated bone resorption markers, vitamin D deficiency, and increased PTH levels in those with MG compared to controls. INTRODUCTION: Muscle strength is closely correlated with bone mineral density (BMD) and vitamin D status. Here, we evaluated muscle strength, BMD, and vitamin D status in a large sample of Chinese patients with MG. METHODS: In this cross-sectional survey, 86 patients with MG without glucocorticoid treatment and 86 healthy controls were included...

BACKGROUND: Burning mouth syndrome (BMS) is a disorder characterized by chronic mouth pain in the absence of objective clinical abnormalities. Vitamin or mineral deficiencies may have a role in BMS, but data regarding the prevalence and relevance of hematinic deficiencies are conflicting. We aimed to determine the frequency of specific laboratory abnormalities in patients with BMS. METHODS: We retrospectively reviewed the results of screening blood tests in patients with BMS at our institution between January 2003 and December 2013...

Jill Thein-Nissenbaum, Erin Hammer
Since the passage of Title IX in 1972, female sports participation has dramatically increased. The benefits of physical activity, including decreased risk for heart disease and diabetes as well as improved body image and self-esteem, far outweigh the risks. However, a select population of adolescent and young adult females may experience symptoms related to the female athlete triad (Triad), which refers to the interrelatedness of energy availability, menstrual function, and bone mineral density (BMD). These conditions often manifest clinically as disordered eating behaviors, menstrual irregularity, and stress fractures; an individual may suffer from 1 or all of the Triad components simultaneously...

PURPOSE: Vitamin D has been known to be involved in mineral and bone homeostasis for many years. In the past its main use was in treating osteoporosis and rickets. In recent years it was found that vitamin D is an immune-modulating agent and may also have a role in several diseases, including autoimmune diseases. The immune-modulating effects appear to be mediated by vitamin D interaction with the vitamin D receptor (VDR) that has transcriptional effects and is expressed on various cell types, especially those of the immune system...

The management of post-transplantation bone disease is a complex problem that remains under-appreciated in clinical practice. In these patients, pre-existing metabolic bone disorder is further impacted by the use of immunosuppressive medications (glucocorticoids and calcineurin-inhibitors), variable post-transplantation renal allograft function and post-transplantation diabetes mellitus. The treatment of post-transplantation bone loss should begin pre-transplantation. All patients active on transplant waiting lists should be screened for bone disease...

Carmel M Hawley, Stephen G Holt
Appropriate targets for parathyroid hormone (PTH) in patients with chronic kidney disease (CKD) stages 3-5D are controversial, as are the means by which these targets might be achieved. Secondary hyperparathyroidism is linked to symptoms like bone pain and itch, in addition to less clinically overt issues like bone fragility as well as vascular and soft tissue calcification which may lead to adverse hard endpoints, particularly fracture and death. Recognized therapies for managing a rising PTH include vitamin D analogues, with or without calcimimetic (where available), in addition to management of serum mineral concentrations with diet, binders and dialysis...

Nigel D Toussaint, Matthew J Damasiewicz
The primary indication for administration of calcitriol or other vitamin D receptor activators (VDRA) in chronic kidney disease (CKD) is secondary hyperparathyroidism (SHPT). Prevention and treatment of SHPT appears important, as imbalances in mineral metabolism are associated with renal osteodystrophy, and higher parathyroid hormone (PTH) levels are associated with increased rates of mortality and morbidity in CKD patients. There is, however, a lack of controlled trial data that show lowering PTH with calcitriol/VDRA equates to improved clinical outcomes...

This review aims to present an innovative concept of high value added lipids produced by heterotrophic microorganisms, bacteria and fungi, using carbon sources, such as sugars, acids and alcohols that could come from sugarcane vinasse, which is the main byproduct from ethanol production that is released in the distillation step. Vinasse is a rich carbon source and low-cost feedstock produced in large amounts from ethanol production. In 2019, the Brazilian Ministry of Agriculture, Livestock and Food Supply estimates that growth of ethanol domestic consumption will be 58...

BACKGROUND: Vitamin D plays a major role in physiological processes that modulate mineral metabolism and immune function with probable link to several chronic and infectious conditions. Emerging data suggests a possible influence of vitamin D on glucose homeostasis. This study sought to provide preliminary information on vitamin D status among Ghanaian type 2 diabetics and assessed its association with glucose homeostasis. METHODS: In a case control study, 118 clinically diagnosed Type 2 Diabetes Mellitus (T2DM) patients attending Diabetic Clinic at the Nkawie Government Hospital were enrolled between October and December 2015...

Different metabolic profiles as well as comorbidities are common in people with Down Syndrome (DS). Therefore it is relevant to know whether micronutrient levels in people with DS are also different. This systematic review was designed to review the literature on micronutrient levels in people with DS compared to age and sex-matched controls without DS. We identified sixty nine studies from January 1967 to April 2016 through main electronic medical databases PubMed, Scopus, and Web of knowledge. We carried out meta-analysis of the data on four essential trace elements (Cu, Fe, Se, and Zn), six minerals (Ca, Cl, K, Mg, Na, and P), and five vitamins (vitamin A, B9, B12, D, and E)...

The aim of this study was to examine usual daily micronutrient intake of Chinese children based on data from the 2011 China Health and Nutrition Survey. We analyzed data from 4 to 17-year-old participants, who provided dietary data on three consecutive days combined with the household weighing method in 2011. Usual daily intake of each nutrient was estimated using a mixed effects model based on the China Food Composition published in 2009. The means, medians and percentages below Estimated Average Requirements (EAR) were reported for selected micronutrients, including calcium, sodium, potassium, iron, zinc, selenium, vitamin A, thiamine, riboflavin and vitamin C...

BACKGROUND: Chronic kidney disease (CKD) is associated with hyperphosphatemia, decreased vitamin D metabolite concentrations, and hyperparathyroidism. This syndrome is known as CKD-mineral bone disorder (CKD-MBD). Recently, it has been shown that an increase in fibroblast growth factor-23 (FGF-23) concentration is an early biomarker of CKD in people. It is an independent risk factor for both progression of renal disease and survival time in humans and cats with CKD. Information about FGF-23 in healthy dogs and those with CKD is lacking...

The aim of this study was to investigate the relationship between dietary habits and hip bone health in community-dwelling individuals with chronic stroke. The usual dietary intake of 94 individuals with chronic stroke (30 women, mean age: 59.0 years) was assessed by a 3-day food record within a single week. Dual-energy X-ray absorptiometry was used to measure bone mineral density (BMD) at both hips. The results showed that low hip bone mass was found in 59 and 50 of the participants on the affected and unaffected side, respectively...

Human immunodeficiency virus (HIV) infection is an established risk factor for low bone mineral density (BMD) and subsequent fracture, and treatment with combination antiretroviral therapy (cART) leads to additional BMD loss, particularly in the first 1-2 years of therapy. The prevalence of low BMD and fragility fracture is expected to increase as the HIV-infected population ages with successful treatment with cART. Mechanisms of bone loss in the setting of HIV infection are likely multifactorial, and include viral, host, and immune effects, as well as direct and indirect effects of cART, particularly tenofovir disoproxil fumarate (TDF) and the protease inhibitors (PIs)...

Methodological aspects of digestibility measurements were studied in four Welsh pony geldings consuming haylage-based diets with increasing proportions of a pelleted concentrate according to a 4×4 Latin square design experiment. Ponies were fed four experimental, iso-energetic (net energy (NE) basis) diets (i.e. 22 MJ NE/day) with increasing proportions of a pelleted concentrate (C) in relation to haylage (H). The absolute amounts of diet dry matter fed per day were 4.48 kg of H (100H), 3.36 and 0.73 kg of H and C (75H25C), 2...
