Introduction. Patients with vibration disease (VD) often have obesity and metabolic syndrome (MS), which increase the risk of developing type 2 diabetes, hypertension, and other conditions predisposing to a decrease in the quality and longevity of life. Genetic predisposition, overnutrition, environmental factors, including industrial ones, and others are factors influencing the formation of MS. The aim of the study is to identify associations between polymorphisms of the LEPR, PPARG and PPARGC1A genes, metabolic syndrome and obesity in VD patients caused by exposure to local vibration and the combined effects of local and general vibration. Material and methods. We examined 248 VD male patients exposed to local vibration and the combined impact of the local and general vibration. We have identified a subgroup of MS and obesity cases. The distribution of genotypes of the LEPR, PPARG and PPARGC1A genes in groups was studied. Results. In the group of VD and MS patients exposed to the combined effect of local and general vibration, the Gln/Gln genotype of the Arg223Gln polymorphic locus of the LEPR gene was less common, and the Arg / Gln genotype in MS cases was detected more often than in patients without it. Among patients with VD caused by exposure to local vibration with a waist circumference of more than 102 cm, the Gly / Ser genotype of the Gly482Ser polymorphism of the PPARGC1A gene was more common than among those with lower values of this indicator. Conclusion. In patients with VD caused by combined exposure to local and general vibration, the Gln/Gln genotype carrier of the Arg223Gln polymorphism of the LEPR gene may play a protective role in the formation of MS. Among individuals with VD caused by exposure to local vibration, carriers of the heterozygous genotype of the Gly482Ser polymorphism of the PPARGC1A gene may have a predisposition to the development of obesity. The obtained results are preliminary and require further research.

Background:Objectives:To assess the potential role of angiopoietin-like protein type 4 (ANGPTL4) in metabolic disorders caused by inflammation in rheumatoid arthritis (RA).Methods:The study included 88 patients with significant RA, 64 patients with other rheumatic diseases (RD) (36 patients with osteoarthritis (OA); 28 patients with psoriatic arthritis (PsA); 17 patients with ankylosing spondylitis (AS)) and 32 healthy individuals. Estimation of ANGPTL4 was carried out by enzyme immunoassay using the commercial test system “RayBio Human ANGPTL4 ELISA Kit” (RayBiotech, USA) in blood serum. Levels of ESR, CRP, RF, antibodies to cyclic citrullinated peptide (anti-CCP) and modified vimentin (anti-MCV) in the ELISA test were determined for all patients with RA.Results:The level of ANGPTL4 in the blood serum of patients with RA was significantly higher than in healthy people (p <0.001) and patients with other RD (p = 0.012 compared with OA; p = 0.046 with PsA; p = 0.008 with AS). ANGPTL4 indices in patients with RA correlated with the age of onset of RA (r = -0.658, p <0.001), disease activity according to DAS-28 (r = 0.449, p = 0.001), level of education (r = 0.235, p = 0.029), dose of glucocorticoid hormones (r = 0.321, p = 0.009) and methotrexate (r = -0.496, p = 0.05), the presence of osteopenia (r = 0.44), signs of kidney damage - proteinuria (r = 0.309, p = 0.037) and hypoalbuminemia (r = 0.386, p = 0.022), as well as with CRP levels (r = 0.488, p = 0.003), ESR (r = 0.458, p = 0.002), serum vitamin D (r = -0.417) and urinary calcium when recalculated to creatinine (r = 0.797, p = 0.032).Patients with RA showed a high frequency of insulin resistance (according to the HOMA-IR index) (1.27 [0.84–1.62] in patients with RA; 0.76 [0.44–1.02] in healthy individuals; p <0.001) and the presence of coronary heart disease, as well as a positive correlation between disease activity (according to DAS-28) and insulin resistance (according to the HOMA-IR index) (p = 0.033).Higher values of C-reactive protein (p = 0.04) and serum ANGPTL4 levels (p = 0.042, compared with patients with RA without type 2 diabetes; p = 0.026, compared with healthy individuals) were determined in the group of patients with RA with the presence of type 2 diabetes. ANGPTL4 acts as an inhibitor of lipoprotein lipase. His contribution to the development of dyslipidemia in RA can be demonstrated by the results we obtained when comparing groups of patients with / without signs of metabolic syndrome (MS). A positive correlation between ANGPTL4 and triglyceride levels (r = 0.42, p = 0.018) was found. An increase in the level of ANGPTL4 in blood serum of patients with RA with MS (p = 0.027 compared with RA without MS) can predict the development of cardiac pathology in this group of patients.Conclusion:ANGPTL4 is directly involved in the regulation of glucose homeostasis, lipid metabolism, and insulin sensitivity. Cardiovascular diseases associated with atherosclerosis, insulin resistance and metabolic syndrome are known as the most common extraarticular manifestations of RA; the study of the role of ANGPTL4 in metabolic disorders caused by inflammation can show a new direction in the development of laboratory and therapeutic technologies in RA.Disclosure of Interests:None declared

Metabolic syndrome is associated with current diseases, such as obesity, diabetes, hypertension, which are accompanied by changes in the intestinal microbiota and the functioning of the immune and neuro-humoral systems of the body. Without detracting from the role of heredity and environmental factors, the intestinal microbiota makes a significant contribution to the development of metabolic disorders and obesity by modulating cascading enzymatic reactions of the macroorganism, interacting with receptors directly and/or using its own metabolites and signaling molecules.The purpose of study was to analyze the literature data obtained in the study of the role of the intestinal microbiota in the development of metabolic syndrome (MS).Results: A review of current literature on the role of intestinal microbiota in the development of metabolic syndrome is presented. The features of the mucosal microflora of the colon, the role of bacterial films, epithelial lining of the intestinal mucosa in the formation of the intestinal microbial-tissue complex as the leading links of metabolic disorders are discussed. The article presents data on the variability of short-chain fatty acids, bacterial genome in the development of obesity and type 2 diabetes.

Sex differences have been well identified in many brain tumors. Even though glioblastoma (GBM) is the most common primary malignant brain tumor in adults and has the worst outcome, well-established differences between men and women are limited to incidence and outcome. Little is known about sex differences in GBM at the disease phenotype and genetical/molecular level. This review focuses on a deep understanding of the pathophysiology of GBM, including hormones, metabolic pathways, the immune system, and molecular changes, along with differences between men and women and how these dimorphisms affect disease outcome. The information analyzed in this review shows a greater incidence and worse outcome in male patients with GBM compared with female patients. We highlight the protective role of estrogen and the upregulation of androgen receptors and testosterone having detrimental effects on GBM. Moreover, hormones and the immune system work in synergy to directly affect the GBM microenvironment. Genetic and molecular differences have also recently been identified. Specific genes and molecular pathways, either upregulated or downregulated depending on sex, could potentially directly dictate GBM outcome differences. It appears that sexual dimorphism in GBM affects patient outcome and requires an individualized approach to management considering the sex of the patient, especially in relation to differences at the molecular level.

PurposeTo analyse the functional and anatomical outcomes of different types of keratoprostheses in eyes with retained silicone oil following vitreoretinal surgery.MethodsRetrospective chart review of patients operated with any type of permanent keratoprosthesis (Kpro) in silicone oil-filled eyes between March 2003 and June 2017 were analysed.Results40 silicone oil-filled eyes underwent keratoprostheses, of which 22 were type 1 and 18 were type 2 Kpros (Lucia variant—nine, modified osteo odonto kerato prosthesis (MOOKP)—four, Boston type 2—three and osteoKpro—two) with a mean follow-up of 61.54 , 42.77, 45.25 , 25 and 37 months, respectively. Anatomic retention of the primary Kpro was noted in 33 eyes (82.5%). A best-corrected visual acuity of better than 20/200 and 20/400 was achieved in 26 (65%)+32 (80%) eyes. Retroprosthetic membrane (RPM) was the most common complication noted in 17 eyes (42.5%). Perioptic graft melt was noted in 4 of 22 eyes of the type 1 Kpro (2 (10.5%) without associated ocular surface disorder (OSD)) and in 1 eye each of Boston and Lucia type 2 Kpro. Laminar resorption occurred in one eye each of the MOOKP and OKP groups. Endophthalmitis and glaucoma did not occur in any eye.ConclusionAppropriately chosen keratoprosthesis is a viable option for visual rehabilitation in eyes post vitreoretinal surgery with retained silicone oil-induced keratopathy not amenable to conventional penetrating keratoplasty. Kpro melt among type 1 Kpro did not occur in 89.5% eyes without associated OSD (19 of 22 eyes), despite the lack of aqueous humour and presence of RPM (4 eyes), two factors considered to play a significant role in the causation of sterile melts. Of interest to note was the absence of infection in any of these eyes. The possible protective role of oil from endophthalmitis is interesting, though yet to be ascertained.

The combination of obesity and type 2 diabetes is a serious health problem, which is projected to afflict 300 million people worldwide by 2020. Both clinical and translational laboratory studies have demonstrated that chronic inflammation is associated with obesity and obesity-related conditions such as insulin resistance. However, the precise etiopathogenetic mechanisms linking obesity to diabetes remain to be elucidated, and the pathways that mediate this phenomenon are not fully characterized. One of the most recently identified signaling pathways, whose activation seems to affect many metabolic disorders, is the “inflammasome,” a multiprotein complex composed of NLRP3 (nucleotide-binding domain and leucine-rich repeat protein 3), ASC (apoptosis-associated speck-like protein containing a CARD), and procaspase-1. NLRP3 inflammasome activation leads to the processing and secretion of the proinflammatory cytokines interleukin- (IL-) 1βand IL-18. The goal of this paper is to review new insights on the effects of the NLRP3 inflammasome activation in the complex mechanisms of crosstalk between different organs, for a better understanding of the role of chronic inflammation in metabolic disease pathogenesis. We will provide here a perspective on the current research on NLRP3 inflammasome, which may represent an innovative therapeutic target to reverse the detrimental metabolic consequences of the metabolic inflammation.

The metabolic disorders are major health issues of today’s scenario and incidences of metabolic diseases increases day by day due to the disturbed pattern of life style. Ayurveda texts have described term “Santarpanjanya Vikaras” which resembles diseases of defective tissue metabolism. Ayurveda mentioned that improper dietary habits and sedentary life style affects state of Agni which resulted Ama production and finally leading to the metabolic syndrome. The vitiation of Dosha, diminish state of Dhatu and blockage of channels, etc. also can initiate pathogenesis of metabolic disorders. The Kayachikitsa branch of Ayurveda recommended use of internal medicine for the management of various metabolic disorders. Considering increased health burden of society due to the metabolic syndrome present article explore role of ayurveda internal medicine for the management of metabolic syndrome. Keywords: Ayurveda, metabolic syndrome, Santarpanjanya, Madhumeha and Sthoulya.

Diabetes Mellitus is a group of metabolic disorders characterized by hyperglycaemic resulting from the defects of insulin secretion, insulin action or both. The present study was conducted in order to know the molecular genetic cause of the T2DM patients belonging to the Jammu region of J&K State. Many genes have been known to be linked with the onset and progression of the T2DM therefore the present data represents the role of one of the genes Uncoupling protein 2 (UCP2) known to be strongly associated with T2DM was selected. A total of 250 confirmed cases & controls samples belonging to four population groups (Hindu, Muslim, Sikh & Christians) of Jammu region were also screened for UCP2 -866G/A promoter polymorphism (rs659366). The allelic odds ratio (OR) as observed for UCP2 -866G/A polymorphism in the four population groups showed significant association with Muslim & Sikh population groups. The study undertaken supports the findings of the previous investigations and thus is an addition to the existing literatute in support of UCP2 and T2DM.

There is ample evidence that insulin resistance, hyperinsulinemia, and obesity are at the heart of the development of non-alcoholic fatty liver disease (NAFLD). The disease is now considered as the hepatic component of metabolic syndrome (MS).64 children with NAFLD were assessed for metabolic syndrome stigma. An analysis was also made on the state of the problem according to the literature on the general links of the pathogenesis of these conditions, methods of diagnosis and treatment of NAFLD.All components of MS are observed with different frequencies in patients with NAFD. This disease, together with type 2 diabetes mellitus, becomes very common diseases in childhood. The incidence of NAFLD in children is constantly growing, it has begun to occur in infants, an outcome in cirrhosis of the liver is possible within childhood, although the prognosis for NAFLD remains definitely uncertain. Weight loss with a low glycemic index diet, regular exercise, and other lifestyle changes are the mainstay of NAFLD treatment, but not yet very effective for various reasons. In these conditions, it is necessary to increase the role of primary prevention of MS and NAFLD.
