Studies from our center and other parts of India have drawn attention towards wide prevalence of vitamin D deficiency (VDD) in our country. VDD has been reported in all age groups including toddlers, school children, pregnant women and their neonates and adult males and females residing in rural and urban India. We reviewed implications of VDD in our population based on the preliminary data available from Indian studies on skeletal health. Besides, a brief review is made on the importance of VDD in various other disorders prevalent in equivalent proportions among Indians such as type 2 diabetes mellitus (DM), cardiovascular diseases (CVD), immune competence including relation to tuberculosis, malignancy and osteoarthritis. Data from the West have also associated VDD with increased prevalence of type 2DM, CVD, autoimmune disorders, tuberculosis, prostate, breast and colon malignancy and osteoarthritis. Such association has not been studied to date in our country. Overall results of various studies conducted to date in urban and rural Indians indicate that widely prevalent VDD is functionally relevant to skeletal health including osteomalacia and rickets. However, there is a need to explore its association with osteoporosis related fractures and various other non skeletal disorders linked with VDD.

Dipeptidyl peptidase IV (DPP IV) is a widely distributed physiological enzyme that can be found solubilized in blood, or membrane-anchored in tissues. DPP IV and related dipeptidase enzymes cleave a wide range of physiological peptides and have been associated with several disease processes including Crohn's disease, chronic liver disease, osteoporosis, multiple sclerosis, eating disorders, rheumatoid arthritis, cancer, and of direct relevance to this review, type 2 diabetes. Here, we place particular emphasis on two peptide substrates of DPP IV with insulin-releasing and antidiabetic actions namely, glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). The rationale for inhibiting DPP IV activity in type 2 diabetes is that it decreases peptide cleavage and thereby enhances endogenous incretin hormone activity. A multitude of novel DPP IV inhibitor compounds have now been developed and tested. Here we examine the information available on DPP IV and related enzymes, review recent preclinical and clinical data for DPP IV inhibitors, and assess their clinical significance.

It is the position of the American Dietetic Association that children ages 2 to 11 years should achieve optimal physical and cognitive development, attain a healthy weight, enjoy food, and reduce the risk of chronic disease through appropriate eating habits and participation in regular physical activity. The health status of American children has generally improved during the past 3 decades. However, the number of children who are overweight has more than doubled among 2- to 5-year-old children and more than tripled among 6- to 11-year-old children, which has major health consequences. This increase in childhood overweight has broadened the focus of dietary guidance to address children's overconsumption of energy-dense, nutrient-poor foods and beverages and physical activity patterns. Health promotion will help reduce diet-related risks of chronic degenerative diseases, such as cardiovascular disease, type 2 diabetes, cancer, obesity, and osteoporosis. This position reviews what US children are eating and explores trends in food and nutrient intakes as well as the impact of school meals on children's diets. Dietary recommendations and guidelines and the benefits of physical activity are also discussed. The roles of parents and caregivers in influencing the development of healthful eating behaviors are highlighted. Specific recommendations and sources of nutrition messages to improve the nutritional well-being of children are provided for food and nutrition professionals

It is unclear whether metformin, one of the anti-hyperglycemic agents commonly used for type 2 diabetes, could affect bone formation through activation of AMP-activated protein kinase (AMPK). In order to clarify this issue, we investigated the effects of metformin on the differentiation and mineralization of osteoblastic MC3T3-E1 cells as well as intracellular signal transduction. Metformin (50 microM) significantly increased collagen-I and osteocalcin mRNA expression, stimulated alkaline phosphatase activity, and enhanced cell mineralization. Moreover, metformin significantly activated AMPK in dose- and time-dependent manners, and induced endothelial nitric oxide synthase (eNOS) and bone morphogenetic protein-2 (BMP-2) expressions. Supplementation of Ara-A (0.1mM), a specific AMPK inhibitor, significantly reversed the metformin-induced eNOS and BMP-2 expressions. Our findings suggest that metformin can induce the differentiation and mineralization of osteoblasts via activation of the AMPK signaling pathway, and that this drug might be beneficial for not only diabetes but also osteoporosis by promoting bone formation.

The results of examination of 116 patients with atherosclerotic damage of lower extremities arteries caused by type 2 diabetes mellitus are presented. At the base of data of X-Ray examination the character, frequency and localization of damage of osteoarticular apparatus of the feet were been analyzed in disorders of main blood flow in cases with diabetes mellitus. Pathologic changes were recorded in 89.9% of cases with prevalence of isolated or combined hypertrophic processes. Destructive alterations, typical for osteoarticular apparatus of the feet in diabetes mellitus (diabetic osteoarthropathy), were absent. X-Ray signs of deformating osteoarthrosis of foot articulations were revealed in 48.4% of cases with maximal rate of damage of metatarsophalangeal joints. No relationship of osteoarticular apparatus lesions rate and a grade of circulation disorder in atherosclerotic vascular disturbances in type 2 diabetes mellitus was revealed (p > 0.05). The frequency of a set of X-Ray signs of osteoarthrosis--narrowing of joint space, subchondral osteosclerosis is associated with duration of diabetes mellitus more than 10 years. The relationship between frequency of development of atrophic processes (osteoporosis) of osteoarticular apparatus of the feet in cases with main vascular disorders and severity of course of diabetes mellitus (p < 0.01). Statistically confident prevalence of rate of osteoarticular apparatus of the foot was recorded in aggravation of metabolic disturbances.

Care of patients with diabetes should include assessment of bone health. The extension of the average life expectancy of people with diabetes, which has accompanied improvements in medical care, has also increased the significance of osteoporosis. In addition to the usual causes of osteoporosis associated with aging, bone health is also compromised by diabetes. Studies on bone involvement in patients with diabetes mellitus have generated conflicting results, largely because of the pathogenetic complexity of the condition. It is now clear that patients with type 1 diabetes have lower bone mineral density (BMD) and a higher risk of fractures. Evidence is emerging that patients with type 2 diabetes who have complications are also at increased risk of certain types of osteoporotic fractures, despite having a higher BMD when compared to patients with type 1 diabetes. Although many factors, including number and type of falls, visual impairment, neuropathy, and reduced muscle strength, influence the probability of fractures, the most significant factor seems to be the strength of the bone itself. Thus, sarcopenia, a reduction in muscle mass and muscle strength, is considered one of the main determinants of bone fragility. The aim of this review is to examine the occurrence of osteoporosis in type 1 and type 2 diabetes.

Hypogonadism in males is a clinical syndrome complex which comprises symptoms with or without signs as well as biochemical evidence of testosterone deficiency. The diagnosis of hypogonadism thus includes both clinical history and examination as well as biochemical assessment of serum testosterone levels. Hypogonadal symptoms depend on the age at onset of hypogonadism, severity of the deficiency, its duration and sensitivity to androgen action. Prepubertal onset results in lack of virilization and pubertal development and produces features such as eunuchoid body proportions and undeveloped secondary sex characteristics. Development of hypogonadism in adult life is characterized by a loss of androgen-dependent functions such as reduction in muscle mass, a shift in body composition towards more adipose tissue, decreased sexual function with diminished libido, depressed mood, loss of psychological energy osteoporosis and several other possible symptoms. The majority of men who suffer from hypogonadism do not have classical endocrine disorders. These men present with concomitant disease such as metabolic syndrome or type 2 diabetes, chronic infections, inflammatory disease, COPD, or cardiovascular disease. All these conditions are associated with a high prevalence of hypogonadism. Pharmacological therapy with opiates and corticosteroids are also known to cause hypogonadism. Hypogonadal symptoms are precipitated at different testosterone levels. Total testosterone levels of less than 8 nmol/l highly support a diagnosis of hypogonadism whereas levels greater than 12 nmol/l are likely to be normal. The grey zone between 8 and 12 nmol/l requires further evaluation and assessment of free or non-sex hormone-binding globulin-bound (bioavailable) testosterone. A trial period of testosterone treatment may be required.

Osteoporosis in elderly men as well as women is increasingly recognized, and patients with type 2 diabetes mellitus have higher risk of fracture than nondiabetic subjects. The aim of the present study was to investigate the relationship between bone stiffness and serum testosterone concentration as well as other variables in men with type 2 diabetes mellitus. The relationships between bone stiffness and serum bioavailable testosterone concentrations as well as other variables including age, duration of diabetes, glycemic control (hemoglobin A(1c)), or body mass index were evaluated in 294 men with type 2 diabetes mellitus. An inverse correlation was found between stiffness index and age. A positive correlation was found between stiffness index and serum bioavailable testosterone concentration (r = 0.231, P = .0005). Stiffness index was significantly less in current smokers (81.6 +/- 17.7) than in past smokers (86.6 +/- 17.8, P = .0396) or nonsmokers (87.7 +/- 15.2, P = .0426). Multiple regression analysis demonstrated that serum bioavailable testosterone concentration (beta = .271, P = .0006) and smoking status (beta = -0.147, P = .0408) were independent determinants of stiffness index. In conclusion, bone stiffness was associated with serum bioavailable testosterone concentration but not associated with hemoglobin A(1c) or duration of diabetes in men with type 2 diabetes mellitus.

Despite an improvement in our understanding of the aetiopathogenesis of diabetic foot problems in the last 2 decades, the 21st Century epidemic of type 2 diabetes will ensure that the incidence of foot problems will continue to increase in the diabetic population. In the aetiopathogenesis it is important to understand that a number of factors working together usually result in foot ulceration: the commonest trio is neuropathy, deformity and trauma. In Western countries, the incidence of neuroischaemic ulcers is now increasing making early detection of those at risk even more important. In the pathogenesis of Charcot neuroarthropathy, recent advances in our understanding of the mechanisms underlying the development of osteopenia and osteoporosis include the central role of the RANK-L OPG signalling system. Finally, in terms of wound healing, the most frequently neglected aspect of care is appropriate offloading of neuropathic or neuroischaemic foot ulcers. The next decades will undoubtedly see the application of stem cell therapy in the management of diabetic foot ulceration.
