Hypertension is a leading risk factor for cardiovascular disease (CVD) and stroke. A common polymorphism in the gene encoding the enzyme methylenetetrahydrofolate reductase (MTHFR), previously identified as the main genetic determinant of elevated homocysteine concentration and also recognized as a risk factor for CVD, appears to be independently associated with hypertension. The B-vitamin riboflavin is required as a cofactor by MTHFR and recent evidence suggests it may have a role in modulating blood pressure, specifically in those with the homozygous mutant MTHFR 677 TT genotype. If studies confirm that this genetic predisposition to hypertension is correctable by low-dose riboflavin, the findings could have important implications for the management of hypertension given that the frequency of this polymorphism ranges from 3 to 32 % worldwide.

Increased Risk

The prevalence of subclinical hypothyroidism (SH) is 3-10%. The prevalence of subclinical hyperthyroidism (SHr) is 0.7-9.7%. Thyroid hormones affect cardiac electrophysiology, contractility, and vasculature. SH is associated with an increased risk of coronary heart disease (CHD), especially in subjects under 65. SHr seems to be associated with a slightly increased risk of CHD and an increase in CHD-related mortality. Both SH and SHr carry an increased risk of developing heart failure (HF), especially in those under 65. Both SH and SHr are associated with worse prognoses in patients with existing HF. SH is probably not associated with atrial fibrillation (AF). SHr, low normal thyroid-stimulating hormone (TSH) and high normal free thyroxine (FT4) are all associated with the increased risk of AF. An association between endothelial dysfunction and SH seems to exist. Data regarding the influence of SHr on the peripheral vascular system are conflicting. SH is a risk factor for stroke in subjects under 65. SHr does not increase the risk of stroke. Both SH and SHr have an unfavourable effect on cardiovascular disease (CVD) and all-cause mortality. There is a U-shaped curve of mortality in relation to TSH concentrations. A major factor that modifies the relation between subclinical thyroid disease (SCTD) and mortality is age. SH increases blood pressure (BP). SHr has no significant effect on BP. Lipids are increased in patients with SH. In SHr, high-density lipoprotein cholesterol and lipoprotein( a) are increased. SCTD should be treated when TSH is over 10 mU/l or under 0.1 mU/l. Treatment indications are less clear when TSH is between normal limits and 0.1 or 10 mU/L. The current state of knowledge supports the understanding of SCTD’s role as a risk factor for CVD development. Age is a significant confounding factor, probably due to age-associated changes in the TSH reference levels.

Introduction: Diabetes mellitus is a well-known risk factor for cardiovascular disease, because of the accelerated process of atherosclerosis. Obesity is an established risk factor and has gained immense importance in recent studies as an important risk factor for clinical cardiovascular disease, yet the fundamental component stays unclear. Calf circumference is another form for lean mass and peripheral subcutaneous fat and is inversely associated with occurrence of carotid plaques (CP). Multiplicative and opposite effects of both Calf Circumference (CC) and Waist Circumference (WC) in event of CP suggest that the two measures should be taken into account commonly while assessing vascular risk profile. Aim & Objective: To ascertain if waist to calf circumference ratio (WCR) is a marker of Carotid atherosclerosis in patients with type 2 diabetes mellitus. To asses s the correlation between waist to calf circumference ratio and carotid intima media thickness (CIMT ) in patients with Type 2 diabetes. Materials and methods: A cross sectional study at Hospital affiliated to Kasturba Medical college Mangalore from Sept 2016 to Sept 2018 . Method of study: Patients with type 2 DM as per ADA criteria, age >18years are recruited for the study. Results and discussion: In our study with 150 population 25 patients had carotid atherosclerosis and 20 patients had CIMT>1.1. The waist circumference in patients with CA is in the range of 93.07 and 99.85 & the CC in patients with CA is in the range of 29.49 to 31.25. The WCR in patients with CA is in the range of 3.12 to 3.26. The difference was statistically significant with a p value of <0.05. In our study it was found that WC and WCR correlated well with carotid atherosclerosis, and surprisingly calf circumference also correlated with carotid atherosclerosis but not as significant as both WC and WCR. Conclusion: To conclude, in our population based study of 150 subjects we found that carotid atherosclerosis is significantly more in people with increased waist calf circumference ratio. WCR may be a new, useful and practical anthropometric index that facilitates the early identification of diabetic subjects with high risk for cardiovascular disease. Validation of this finding in individual populations is required. Future studies should test the association of calf circumference with carotid intima media thickness and carotid plaques using better measures than ultrasound such as magnetic resonance imaging. Further research focusing on underlying mechanisms in the role of lean mass and peripheral fat mass is required.

Riboflavin Transport

Background: the SLC52A2 gene encodes for the riboflavin transporter 2 (RFVT2). This transporter is ubiquitously expressed. It mediates the transport of Riboflavin across cell membranes. Riboflavin plays a crucial role in cells since its biologically active forms, FMN and FAD, are essential for the metabolism of carbohydrates, amino acids, and lipids. Mutation of the Riboflavin transporters is a risk factor for anemia, cancer, cardiovascular disease, neurodegeneration. Inborn mutations of SLC52A2 are associated with Brown-Vialetto-van Laere syndrome, a rare neurological disorder characterized by infancy onset. In spite of the important metabolic and physio/pathological role of this transporter few data are available on its function and regulation. Methods: the human recombinant RFVT2 has been overexpressed in E. coli, purified and reconstituted into proteoliposomes in order to characterize its activity following the [3H]Riboflavin transport. Results: the recombinant hRFVT2 showed a Km of 0.26 ± 0.07 µM and was inhibited by lumiflavin, FMN and Mg2+. The Riboflavin uptake was also regulated by Ca2+. The native protein extracted from fibroblast and reconstituted in proteoliposomes also showed inhibition by FMN and lumiflavin. Conclusions: proteoliposomes represent a suitable model to assay the RFVT2 function. It will be useful for screening the mutation of RFVT2.

Non Coding Rnas

The discovery of non-coding RNAs (ncRNAs) has opened a new paradigm to use ncRNAs as biomarkers to detect disease progression. Long non-coding RNAs (lncRNA) have garnered the most attention due to their specific cell-origin and their existence in biological fluids. Type 2 diabetes patients will develop cardiovascular disease (CVD) complications, and CVD remains the top risk factor for mortality. Understanding the lncRNA roles in T2D and CVD conditions will allow the future use of lncRNAs to detect CVD complications before the symptoms appear. This review aimed to discuss the roles of lncRNAs in T2D and CVD conditions and their diagnostic potential as molecular biomarkers for CVD complications in T2D.
