Zinc inhibits vascular calcification in vivo and in vitro. Patients with type 2 diabetes mellitus show hypozincemia and are at an elevated risk of cardiovascular events. Recently, an in vitro test (T50-test) was developed for determination of serum calcification propensity and a shorter T50 means a higher calcification propensity. This cross-sectional study investigated the association between serum zinc and T50 in 132 type 2 diabetes mellitus patients with various kidney functions. Furthermore, the effect of exogenous zinc on T50 was also investigated in vitro using separately pooled serum samples obtained from healthy volunteers and patients with hemodialysis. We measured T50 levels using the established nephelometric method. The median (interquartile range) levels of T50 and serum zinc were 306 (269 to 332) min, and 80.0 (70.1 to 89.8) µg/dL, respectively. Serum zinc level showed a weak, but positive correlation with T50 (rs = 0.219, p = 0.012). This association remained significant in multivariable-adjusted analysis, and was independent of known factors including phosphate, calcium, and magnesium. Kidney function and glycemic control were not significantly associated with T50. Finally, in vitro experiments showed that addition of a physiological concentration of exogenous zinc chloride significantly increased serum T50. Our results indicate that serum zinc is an independent factor with a potential role in suppressing calcification propensity in serum.

Abstract Background: Zinc inhibits vascular calcification in vivo and in vitro. Patients with type 2 diabetes mellitus show hypozincemia and are at an elevated risk of cardiovascular events. Recently, the in vitro test (T50-test) was developed for the determination of serum calcification propensity. This cross-sectional study investigated the association between serum zinc and T50 in type 2 diabetes mellitus patients and the effect of zinc on T50in vitro.Methods: The subjects were 132 type 2 diabetes mellitus patients with various kidney function. We measured T50 levels by the established nephelometric method.Results: The median (interquartile range) levels of T50 and serum zinc were 306 (269 to 332) min, and 80.0 (70.1 to 89.8) µg/dL, respectively. Serum zinc level was significantly and positively correlated with T50 (rs = 0.219, p = 0.012). This association remained significant in multivariable-adjusted analysis, and was independent of known factors including phosphate, calcium, and magnesium. Renal function and glycemic control were not significantly associated with T50. Finally, addition of physiological concentration of exogenous zinc chloride significantly increased the serum T50 in vitro.Conclusions: This is the first report to investigate the association between serum calcification propensity and zinc levels in type 2 diabetes mellitus patients. Our data suggest that serum zinc is an independent factor that inhibits serum calcification propensity.

Background: Studies show that diabetes mellitus is the greatest lifestyle risk factor for dementia. Appropriate management and treatment of type 2 diabetes mellitus could prevent the onset and progression of mild cognitive impairment to dementia. MoCA test is high sensitivity with mild dementia but it have not been used and studied widespread in Vietnam. Aim: 1. Using MoCA and MMSE to diagnose dementia in patients with type 2 diabetes mellitus. 2. Assessment of the relationship between dementia and the risk factors. Methods: cross-sectional description in 102 patients with type 2 diabetes mellitus. The Mini-Mental State Examination(MMSE) and the Montreal Cognitive Assessment (MoCA) were used to assess cognitive function. The diagnosis of dementia was made according to Diagnostic and Statistical Manual of Mental Disorders. Results: The average value for MoCA in the group of patients with dementia (15.35 ± 2.69) compared with non-dementia group (20.72 ± 4.53). The sensitivity and specificity of MoCA were 84.8% and 78.3% in identifying individuals with dementia, and MMSE were 78.5% and 82.6%, respectively. Using DSMIV criteria as gold standard we found MoCA and MMSE were more similar for dementia cases (AUC 0.871 and 0.890). The concordance between MoCA and MMSE was moderate (kappa = 0.485). When considering the risk factors, the education,the age, HbA1c, dyslipidemia, Cholesterol total related with dementia in the type 2 diabetes. Conclusion: MoCA scale is a good screening test of dementia in patients with type 2 diabetes mellitus.When compared with the MMSE scale, MoCA scale is more sensitive in detecting dementia. Key words: MoCA, dementia, type 2 diabetes mellitus, risk factors

To analyze the correlation between functional health literacy (FHL) and self-efficacy (SE) in people with type 2 Diabetes Mellitus. Cross-sectional study was conducted among September and October 2019, with 196 people with type 2 diabetes. Data were collected using the Functional Literacy in Health instrument (B-TOFHLA) and the Diabetes Management Self-Efficacy Scale for Patients with Type 2 Diabetes Mellitus (DMSES). Bivariate analysis was used to verify the relationship among the constructs. Most diabetics showed an average B-TOFHLA score of 74.75, considered adequate, and self-efficacy of 4.07, high. The association between SE and FHL in the bivariate analysis found no statistical significance ( p > .05), in the same sense as the B-TOFHLA score and the DMSES domains ( p > .05). Constructs were not related to each other in terms of skills arising from judgments and decisions with motivational confidence by the investigated audience.
