BACKGROUND: Endothelial progenitor cells (EPCs) are a population of bone marrow-derived cells, which have an important role in the process of endothelialization and vascular repair following injury. Impairment of EPCs, which occurs in patients with diabetes, was shown to be related to endothelial dysfunction, coronary artery disease (CAD) and adverse clinical outcomes. Recent evidence has shown that calcitriol, the active hormone of vitamin D, has a favorable impact on the endothelium and cardiovascular system...

The current study was conducted to assess the effect of hemodialysis (HD) on the status of plasma oxidants and antioxidants among patients with end-stage renal disease (ESRD). These parameters can have an influence on the HD process and can also be useful for follow-up of these patients. The participants of this cross-sectional study comprised 91 patients with a mean age of 51.1 ± 8.2 years on chronic HD with kt/v between 1.2 and 1.4. The etiology of ESRD in these patients was as follows: diabetes mellitus in 39, hypertension in 35, and glomerulonephritis in 17 patients...

Low serum levels of 25 hydroxyvitamin D (25OHD) (hypovitaminosis D) is common in older adults and associated with several negative outcomes. The association between hypovitaminosis D and diabetes in older adults is equivocal, however. We conducted a meta-analysis investigating if hypovitaminosis D is associated with diabetes in prospective studies among older participants. Two investigators systematically searched major electronic databases, from inception until 10/07/2016. The cumulative incidence of diabetes among groups was estimated according to baseline serum 25OHD levels...

OBJECTIVES: Deficiency of 25-hydroxyvitamin D (25[OH]D) is associated with increased risk for cardiovascular disease, perhaps mediated through dyslipidemia. Deficient 25(OH)D is cross-sectionally associated with dyslipidemia, but little is known about longitudinal lipid changes. The aim of this study was to determine the relationship of 25(OH)D deficiency to longitudinal lipid changes and risk for incident dyslipidemia. METHODS: This was a longitudinal community-based study of 13 039 participants from the ARIC (Atherosclerosis Risk in Communities) study who had 25(OH)D and lipids measured at baseline (1990-1992) and lipids remeasured in 1993 to 1994 and 1996 to 1998...

BACKGROUND: In primary hyperparathyroidism, successful parathyroidectomy leads to improved bone mineral density in the majority of cases. Our aim was to further explore the relationship between hypercalciuria, kidney function, and bone recovery after parathyroidectomy. METHODS: Bone mineral density, estimated glomerular filtration rate, and 24-hour urinary calcium were analyzed before and one year after parathyroidectomy in a cohort of 150 primary hyperparathyroidism patients (119 women; median age 60 [range 30-80] years) taking part in a clinical trial...

OBJECTIVE: Polycystic ovary syndrome (PCOS) is a condition of androgen excess and chronic anovulation frequently associated with insulin resistance. We combined a nontargeted and targeted metabolomics approach to identify pathways and metabolites that distinguished PCOS from metabolic syndrome (MetS). METHODS: Twenty obese women with PCOS were compared with 18 obese women without PCOS. Both groups met criteria for MetS but could not have diabetes mellitus or take medications that treat PCOS or affect lipids or insulin sensitivity...

Nutrients that regulate methylation processes may modify susceptibility to the effects of air pollutants. Data from the National Birth Defects Prevention Study, 1997-2006, were used to estimate associations between maternal exposure to nitrogen dioxide (NO2), dietary intake of methyl nutrients and the odds of congenital heart defects in offspring. NO2 concentrations, a marker of traffic-related air pollution, averaged across post-conception weeks 2-8, were assigned to 6160 non-diabetic mothers of cases and controls using inverse distance-squared weighting of air monitors within 50 km of maternal residence...

BACKGROUND & AIMS: Tuberculosis (TB) patients have a significant vitamin D deficiency (VDD) endemic, which may be closely related to the onset and progress of the disease. The comorbidity of diabetes (DM) and TB has posed an increasing challenge in recent years. However, the influence of DM on TB and the possible mechanism are still uncertain. We carried out this study to identify the nutritional status of vitamin D (VD) in TB patients in a northern city in China (latitude 36° N) and investigate the possible predictors of severe vitamin D deficiency (SVDD)...

The antioxidant protein haptoglobin (Hp) plays a major role in the development of diabetic complications such as diabetic nephropathy and retinopathy. In humans, two alleles of Hp were identified: 1 and 2 with three possible genotypes: 1-1, 2-1, and 2-2. The Hp protein products differ in their biochemical and biophysical properties, such as their antioxidant capacity. The Hp1 protein is superior to the Hp2 protein in binding to free hemoglobin and neutralizing its oxidative potential and the accompanying renal and retinal injury...

Globally type 1 diabetes incidence is increasing. It is widely accepted that the pathophysiology of type 1 diabetes is influenced by environmental factors in people with specific human leukocyte antigen haplotypes. We propose that a complex interplay between dietary triggers, permissive gut factors and potentially other influencing factors underpins disease progression. We present evidence that A1 β-casein cows' milk protein is a primary causal trigger of type 1 diabetes in individuals with genetic risk factors...
