Vitamin D deficiency is a well-established risk factor for bone disease. Emerging data suggest a pleiotropic role of this agent in a variety of functions in humans. Epidemiological studies indicate an inverse association between vitamin D deficiency and the prevalence of cardiovascular disease (CVD), as well as individual cardiometabolic risk factors, such as hypertension, diabetes, dyslipidemia and the metabolic syndrome. Moreover, vitamin D deficiency has been implicated in the atherosclerotic process. This review considers current data regarding the role of vitamin D deficiency in the development of CVD and addresses the effect of supplementation on cardiovascular outcomes.

Childhood obesity affects 17% or 12.5 million of America's children, contributing to the rise in children's health disparities. Type 2 diabetes, asthma, vitamin D deficiency, and attention-deficit/hyperactivity disorder have also increased over the past few decades. A shift toward a sedentary lifestyle is a major contributor to the decline in children's health. Children spend more time indoors using electronic media and less time engaged in outdoor unstructured play. This article reviews the current evidence of the mental and physical health benefits associated with unstructured, outdoor activities and time spent in a natural environment such as a park or other recreational area. Pediatric health care providers should recommend outdoor activities for children and refer families to safe and easily accessible outdoor areas. Pediatric health care providers can incorporate this simple, lifestyle-based intervention into anticipatory guidance.

African Americans have a higher prevalence of Diabetes mellitus and associated complications. The prevalence of Vitamin D deficiency is also higher in African Americans. We report an African American veteran who was followed for a period of 10 years in the Endocrine clinic for insulin-requiring diabetes. Despite intensive, medical, nutritional and educational efforts during that period, no discernible progress was made in achieving any improvement in glycemic control. The patient appeared to be noncompliant with recommended strategies to improve glycemia. The patient was seen recently and was found to be profoundly Vitamin D deficient with a 25 (OH) Vitamin D level of 11.6 ng/ml [30-100 ng/ml]. While patient did not wish to change his insulin regimen or diabetic management, he was willing to accept Vitamin D therapy. Replacement with Vitamin D was associated with significant improvement in glycosylated hemoglobin to previously unmatched levels of glycemic control. We discuss the multiple potential mechanisms by which improved Vitamin D status may result in improved diabetes control. Given the current pandemic of Vitamin D deficiency and the plethora of potential benefits, we recommend maintaining adequate Vitamin D reserves in diabetic patients with a special emphasis on minority populations.

Vitamin D deficiency is becoming increasingly common in the USA. In this review we provide estimates of the prevalence of deficiency, and review the risk factors and the evidence of clinical consequences of vitamin D deficiency. Vitamin D deficiency causes the pediatric disease rickets. In addition, there is some evidence that vitamin D deficiency may lead to other diseases including diabetes mellitus, hypertension, infections, asthma and dyslipidemia.

Vitamin D is a group of lipophilic hormones with pleiotropic actions. It has been traditionally related to bone metabolism, although several studies in the last decade have suggested its role in muscle strength and falls, cardiovascular and neurological diseases, insulin-resistance and diabetes, malignancies, autoimmune diseases and infections. Vitamin D appears to be a hormone with several actions and is fundamental for many biological systems including bone, skeletal muscle, brain and heart. The estimated worldwide prevalence of vitamin D deficiency of 50% in elderly subjects underlines the importance of vitamin D deficiency for public health. In this review, we will describe changes in vitamin D levels with age in both sexes, cut off values to define Vitamin D status, the impact of vitamin D deficiency in age-related disease and finally different therapeutic options available to treat Vitamin D deficiency in older populations.

Recently, vitamin D has aroused considerable interest for several reasons. Many epidemiological studies have shown a widespread deficiency of vitamin D at all ages, and the recent finding that many organs and tissues have vitamin D receptors has fostered the clinical and biological relevance of vitamin D. Elderly people are at high risk for vitamin D deficiency if their life style entails few outdoor activities, their skin is thick and they exhibit impairment of renal function. In the elderly, vitamin D deficiency is very important because it can affect the function of many organs such as the muscle-skeletal, cardio-vascular systems and kidney, and may be involved in various diseases and pathological conditions including type II diabetes, cancer and cognitive decline. In the present review, the most relevant features of vitamin D are described as well as the clinical consequences of hypovitaminosis D in the elderly. Finally, the role of an adequate oral supplementation in the geriatric population is stressed.

The adverse effect of an increased life expectancy for people with cystic fibrosis (CF) is the increased risk of complications, such as CF-related low bone mineral density (BMD). Diagnosis of CF-related low BMD is confirmed by a dual-energy X-ray absorptiometry (DXA) scan. This study reports the results of an audit of DXA scans in 108 adults with CF in our clinic. The most common risk factors for bone loss were vitamin D deficiency (89%), CF-related diabetes (53%), low body mass index (39%) and post-lung transplant (25%); half of those with bone loss were genotype homozygous DF508. Overall fracture incidence was 5.5%; low BMD was not associated with high fracture rates. Thus BMD may not be a good predictor of fracture risk. Treatment includes bisphosphonates, which are difficult to take and have uncertain long-term effects. It is unknown whether bisphosphonate therapy is justified in this already overburdened group.

There has been an important shift in the views about the actions of vitamin D during the past decade. In addition to its well-established role in the regulation of calcium metabolism, vitamin D deficiency has been associated with the risk of several extra-skeletal diseases, including type 1 diabetes among other chronic conditions. It is notable that 1,25(OH)(2)D is known to regulate the expression of over 200 different genes, including the ones related to apoptosis and immune modulation. Increased vitamin D intake is currently considered as one of the most promising candidates for the prevention of type 1 diabetes, and it has been suggested that changes in vitamin D intake during the past decades have contributed to the recent trends in the incidence of the disease. This study reviews the evidence for the role of vitamin D in type 1 diabetes development, demonstrating that support has been obtained from various lines of investigation and that the possible biological mechanisms are plausible. However, much of the evidence has been obtained from animal experiments or observational studies in humans and there is an urgent need for well-designed, randomized, controlled trials to show whether the observed associations are indeed causal.

Insulin resistance (IR), the reciprocal of insulin sensitivity is a known complication of advanced chronic kidney disease (CKD) and is associated with a number of metabolic derangements. The complex metabolic abnormalities observed in CKD such as vitamin D deficiency, obesity, metabolic acidosis, inflammation, and accumulation of "uremic toxins" are believed to contribute to the etiology of IR and acquired defects in the insulin-receptor signaling pathway in this patient population. Only a few investigations have explored the validity of commonly used assessment methods in comparison to gold standard hyperinsulinemic hyperglycemic clamp technique in CKD patients. An important consequence of insulin resistance is its role in the pathogenesis of protein energy wasting, a state of metabolic derangement characterized by loss of somatic and visceral protein stores not entirely accounted for by inadequate nutrient intake. In the general population, insulin resistance has been associated with accelerated protein catabolism. Among end-stage renal disease (ESRD) patients, enhanced muscle protein breakdown has been observed in patients with Type II diabetes compared to ESRD patients without diabetes. In the absence of diabetes mellitus (DM) or severe obesity, insulin resistance is detectable in dialysis patients and strongly associated with increased muscle protein breakdown, primarily mediated by the ubiquitin-proteasome pathway. Recent epidemiological data indicate a survival advantage and better nutritional status in insulin-free Type II DM patients treated with insulin sensitizer thiazolidinediones. Given the high prevalence of protein energy wasting in ESRD and its unequivocal association with adverse clinical outcomes, insulin resistance may represent an important modifiable target for intervention in the ESRD population.

Traditionally, patients with type 1 diabetes were regarded to be at an increased risk of fractures whereas type 2 diabetics were assumed to be protected from fractures since many of them have high bone mineral density. Nevertheless, several clinical studies consistently demonstrated that type 2 diabetes is a paradigm of a disease with an increased risk of fractures in the presence of high bone mass. The pathophysiology of decreased bone strength in diabetes mellitus is multifactorial: insulin deficiency, insulin resistance, osteoblast insufficiency, vitamin D deficiency, formation of advanced glycation end-products in bone, and microvascular complications appear to contribute. Drugs used for the treatment of type 2 diabetes also may influence bone fragility: thiazolidinedione use has been associated with an increased risk of fractures.
