To investigate the value of 24 hours post-surgery measurement of growth hormone (GH) level for prognosis of surgical outcomes in acromegaly.

A prospective cohort study included 45 patients with newly diagnosed acromegaly. The degree of parasellar extension was measured on the preoperative sellar magnetic resonance imaging according to the Knosps classification. All patients underwent a transsphenoid adenomectomy performed by one neurosurgeon. AT9283 concentration Basal GH level was measured at 24 hours after surgery. The efficacy of transsphenoidal adenomectomy evaluated at 12 months after surgery.

Acromegaly remission was achieved in 19 (42%) of 45 patients at 12 months after surgery. Pituitary microadenomas and the absence of paracellular invasion, corresponding to Knosp Grade 02, had low prognostic value for long-term remission due to low sensitivity (31.6%) and low specificity (38.5%), respectively. The highest prognostic value for acromegaly remission was showed for 24 hours post-surgery GH level with cut-off 1.30 ng/m for more close monitoring of patients in the postoperative period. Further studies in a larger number of observers are required to confirm our findings.

To study the possibility of using polymorphisms of genesTCF7L2,FABP2,KCNQ1,ADIPOQas markers for predicting the development of type 2 diabetes mellitus (T2D) in the population of Novosibirsk.

On the basis of prospective observation of a representative population sample of residents of Novosibirsk (HAPIEE), 2 groups were formed according to the case-control principle (case people who had diabetes mellitus 2 over 10 years of observation, and control people who did not developed disorders of carbohydrate metabolism). T2D group (n=443, mean age 56.26.7 years, men 29.6%, women 70.4%), control group (n=532, mean age 56.17.1 years, men 32.7%, women 67.3%). DNA was isolated by phenol-chloroform extraction. Genotyping was performed by the method of polymerase chain reaction with subsequent analysis of restriction fragment length polymorphism, polymerase chain reaction in real time. Statistical processing was carried out using the SPSS 16.0 software package.

No significant effect of rs1799883 of theFABP2gene, rs22ment of T2D polymorphisms rs1799883 of theFABP2gene, rs2237892 of theKCNQ1gene and rs6773957 of theADIPOQgene was not found.

The rs7903146 polymorphism of theTCF7L2gene confirmed its association with the prognosis of the development of T2D, which indicates the possibility of considering it as a candidate for inclusion in a diabetes risk meter. Variants of risk meters have been developed to assess the prognosis of the development of diabetes mellitus 2 in men and women aged 4569 years during 10 years of follow-up. The association with the prognosis of the development of T2D polymorphisms rs1799883 of theFABP2gene, rs2237892 of theKCNQ1gene and rs6773957 of theADIPOQgene was not found.

The purpose of the study is to increase the effectiveness of treatment of metabolic syndrome (MS) in young patients with vitamin D deficiency.

The study involved 54 patients with MS and vitamin D deficiency (50% of women, 50% of men), aged 2044years. To assess the concentration of melatonin at a young age, a control group of 42 practically healthy volunteers with comparable demographic characteristics with no signs of MS was formed.

In patients with MS and vitamin D deficiency, there was a significant decrease in the average daily level of 6-sulfatoxymelatonin in the urine by 3.7 times, compared with the group of individuals without MS. Patients with MS and vitamin D deficiency (n=54) were randomly assigned to two groups with comparable clinical and demographic characteristics. Patients of the 1st group (n=27) observed dietary recommendations and took the drug Metformin at a dose of 1700 mg/day for 12 months. In the 2nd group (n=27), in addition to the one indicated in the 1st treatment group, correctiolatonin) and, if it decreases, carry out correction of melatonin and 25 (OH) vitamin D in addition to the standard therapy of this syndrome.

To assess the influence of diabetes mellitus and obesity on contrast-induced acute kidney injury risk in patients with chronic coronary artery disease requiring percutaneous coronary intervention.

1023 patients with chronic coronary artery disease were enrolled in a prospective, open, cohort study (ClinicalTrials.gov ID NCT04014153). Contrast-induced acute kidney injury was defined as an increase of 25% or more, or an absolute increase of 0.5 mg/dl or more in serum creatinine from baseline value, assessed at 48 hours following the administration of the contrast. The majority of the patients were overweight male ones with BMI 29.25.5 kg/m2. The primary endpoint of the study was the development of contrast-induced acute kidney injury according to KDIGO criteria.

The prevalence of contrast-induced acute kidney injury was 12.9% (132 patients). 21.2% suffered from diabetes mellitus, 43% were obese and 12.9% had both diabetes mellitus and obesity. Diabetes wasnt a statistically significant independent risk fat meet statistical significance and needs further evaluation in larger studies.

To investigate parameters of angiogenesis system in patients with diabetes mellitus and their relationship with obesity.

104 patients with diabetes mellitus type 2 were included in the study. Patients were divided in 2 groups Obesity+ (body mass index30 kg/m2;n=63) and Obesity- (body mass index 30 kg/m2;n=41). In all patients was performed clinico-diagnostical examination. mRNA expression levels of vascular endothelial growth factor (VEGF), its receptors flt-1 (fms-like tyrosine kinase 1), KDR (human kinase insert domain receptor) were determined in blood mononuclear cells.

There were no statistically significant differences in investigated parameters between study groups. mRNA expression level of VEGF was slightly lower in men compared to women 0.19 (0.14; 0.32)vs0.28 (0.12; 0.4) respectively,р=0.2236. MRNA expression level of flt-1 was lower in men compared to women 0.14 (0.04; 0.3)vs0.25 (0.12; 0.38),р=0.0321 (statistically significant). We found statistically significant correlations of mRNA expression level of VEGF with mRNA expression level of flt-1 and KDR.
