Background. According to the International Diabetes Federation, the number of people with diabetes mellitus is going to increase from 366 to 552 million by 2030. More than 1.5 million patients with diabetes are registered in Ukraine, of which 84–95 % have type 2 diabetes. Diabetic retinopathy (DR) is one of the common diabetes complications, being one of the leading causes of blindness and low vision, in particular in people of occupational age. Metabolic disorders, including activation of the polyol pathway of glucose utilization, play an important role in the pathogenesis of DR, with aldose reductase playing a key role, the activity of which is associated with the polymorphism of its gene, AKR1B1. The study of new meta­bolic and genetic mechanisms for the development and progression of DR in type 2 diabetes mellitus in patients from the Ukrainian population is an actual task of modern ophthalmology. Purpose: to investigate and generalize new genetically determined risk factors for diabetic retinopathy in type 2 diabetes mellitus. Materials and methods. The study involved 409 participants, who were divided into four groups: 1 — comparison cohort (98 people without diabetes mellitus type 2); 2 — 76 patients (stage I DR, without fundus chan­ges); 3 — 64 individuals with non-proliferative DR; 4 — 64 patients with proliferative DR; control group for genetic researches included 107 ophthalmologically healthy individuals. All patients underwent blood sampling for molecular genetic research by puncture of the ulnar vein and aspiration of 2.5 ml of blood through a 23G 5.0 ml disposable syringe (Hemoplast, Etalon+, Ukraine), followed by a release into a 3.0 ml container (Vacuette K3E K3EDTA, Greiner Bio-One, Austria). Distribution of polymorphic alleles and genotypes of rs759853 and rs9640883 aldose reductase gene (AKR1B1) in patients with non-proliferative DR, proliferative DR and in the control group and their association with disease and effects on the occurrence, mechanisms of development and progression of DR were studied. Based on the conducted researches, a model of DR development prognosis was developed by construction of multiple regression with sufficient reliability of degree of influence of independent variables on a calculated indicator. Results. As a result of our research, we identified new genetically determined risk factors for the development and progression of the different stages of DR in patients with diabetes mellitus type 2, namely the role of polymorphic alleles and genotypes rs759853 and rs9640883 of the AKR1B1 gene. The deve­loped logistic regression models found that the risk of DR incidence is five times lower in carriers of the G/G and G/A genotypes compared to carriers of the A/A genotype rs759853 polymorphism (p < 0.001). It was found that the risk is twice as high (p = 0.01) for carriers of the G/G genotype rs9640883 compared to the A/A + G/A genotypes. The risk of developing proliferative DR is 3.3 times lower in carriers of the G/G genotype and 2.5 times lower in carriers of the G/A genotype compared to carriers of the A/A genotype rs759853. Conclusions. Therefore, on the basis of our clinical, ophthalmological, molecular genetic and statistical studies we have identified new risk factors for the development and progression of different stages of DR in patients with diabetes mellitus type 2. Mathematical models of development and progression of different stages of DR in patients with diabetes type 2 were built.

Background: Diabetes mellitus and depression are highly prevalent conditions throughout the world and have significant impact on health outcomes. It has been estimated that diabetes mellitus type 2 affects about 246 million people in the world; nevertheless, incidence varies among countries. There is evidence that depression is associated with a poor metabolic control in patients with type 2 diabetes mellitus that present other health problems (such as hypertension and obesity). The aim of this study protocol is to determine if obesity increases the risk for depression in patient with diabetes type 2.Methods: The analysis will be reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA).The studies suitable for inclusion will be assessed by the Newcastle-Ottawa Scale (NOS) to determine their methodological quality. To identify the studies of interest, we will search on PubMed and EBSCO databases. We will use the following keyword combinations: "Diabetes Mellitus type 2 AND obesity AND depression", "depression AND Diabetes Mellitus type 2", "Diabetes Mellitus type 2 AND body mass index cross sectional study", "depression AND obesity cross-sectional study". Causes for exclusion will be publications that studied patients diagnosed with diabetes mellitus type 1; articles that focused on the treatment and complications of diabetes mellitus type 2; publications that have studied other clinical or psychiatric conditions (for instance, seizure disorder or history of schizophrenia, bipolar disorder, psychotic symptoms or dementia).Conclusion: The results of this study will form the basis for a better understanding of the association between obesity and depression in patients with diabetes mellitus type 2, and will allow development of prediction tools and better interventions. It is evident that several modifiable and non-modifiable risk factors play an important role in the pathogenesis of diabetes among population. Currently, evidence for the deleterious effects of diabetes mellitus type 2 are based on cross-sectional or other observational designs. Therefore, this study will have important implications for future research and public health guidance.

Diabetes mellitus represents a serious medico-social problem that is caused by its high prevalence, a tendency to body height of number ofpatients, a high invalidism and a mortality. The main reason for death ofpatients with a diabetes mellitus type 2 is the pathology of cardiovascular system bound to an atherosclerosis to which leads lack of adequate compensation of a disease. In this article various risk factors of cardiovascular pathology at patients with a diabetes mellitus are surveyed and modern opportunities in their correction are discussed.

Introduction:The study evaluated of microalbuminuria as a predictor of heart failure in patients with diabetes mellitus type 2.Materials and methods:The prospective study conducted in a period of time from 01-Feb-2007 to 01-Feb-2010.The study included 100 patients with type 2 diabetes, who had diabetes longer than 5 years. All subjects (average age 66 ± 10 years, 33% male, 67% female) were tested for the presence of microalbuminuria, and 50 patients had microalbuminuria. The second group comprised 50 patients without of microalbuminuria with diabetes mellitus type 2.Results:In the patients with microalbuminuria and diabetes mellitus were found 22% of heart failure and 6% in the second group. Average time to the occurance of heart failure in the first group was 32,5 months, in the second group was 35,3 months.Conclusions:The results show that microalbuminuria is an independent risk factor for heart failure in patients with diabetes mellitus type 2 and microalbuminuria. Patients without microalbuminuria had 3,7 less likely to development heart failure compared to patients with microalbuminuria and diabetes mellitus.
