Gout and diabetes mellitus are metabolic diseases, the pathogenesis of which is based on an excess of organic molecules in the body, in the first case — uric acid (UA), in the second — glucose. It is assumed that UA can also be involved in the pathogenesis of type 2 diabetes mellitus (T2DM), while insulin resistance and hyperglycemia affect purine metabolism. Both diseases are associated with an increased risk of cardiovascular events. In addition, chronic microcrystalline inflammation, which is absent in asymptomatic hyperuricemia, but is an obligatory component of gout, is probably an independent factor in T2DM, arterial hypertension, and cardiovascular events. The treatment of both diseases is strategically similar: in gout, the goal is to achieve a normal blood MC level, in T2DM — to normalize glycemia, and the frequent combination of these metabolic diseases requires taking into account the effect of drug therapy on concomitant diseases. Most modern antihyperglycemic drugs can affect purine metabolism, which is confirmed by the results of a number of foreign works. At the same time, the effect of T2DM therapy on purine metabolism and gout has not been adequately covered in the domestic literature, which was the purpose of this review.

One of the most global health problems today is the SARS-CoV-2 coronavirus pandemic and its numerous complications. COVID-19 was first reported in China in the city of Wuhan in December 2019. It was found that coronavirus infection leads to microvascular and macrovascular complications throughout the body. Recent data indicate a strong link between severe clinical manifestations of COVID-19 and an increased risk of thromboembolism. It is associated with several risk factors such as systemic hyperinflammation caused by coronavirus infection, hypoxia, and comorbidities. The pathophysiological mechanisms underlying coagulopathy associated with COVID-19 include diffuse damage to endothelial cells, abnormal blood flow dynamics, and uncontrolled platelet activation. Studying the situation during the COVID-19 pandemic, we can notice that patients develop various complications during or after COVID-19. This article describes a clinical case of a patient with type 2 diabetes mellitus who has developed cavernous sinus thrombosis complicated by osteomyelitis of the upper jaw after COVID-19 infection.

Background: A large number of studies have demonstrated that LVH detected with standard electrocardiography is an independent predictor of future cardiovascular complications in various subsets of patients. Despite the fact that ECG represents the first cardiovascular test performed in diabetics, few data are available on the prognostic significance of EKG LVH in these patients. Aim of this study was to evaluate the relationship between EKG LVH and the risk of future cardiovascular events in a wide group of patients with diabetes mellitus (DM). Methods A total of 1131 prospectively identified patients with type 1 (n=613, age 36 ± 13 years, 40 % women, BP 127 ± 16/79 ± 8 mmHg, total cholesterol 196 ± 43 mg/dl, HbA1C 7.81 ± 1.67%) and with type 2 DM (n=618, age 53 ± 11 years, 34 % women, BP 137 ± 18/82 ± 8 mmHg, total cholesterol 208 ± 41 mg/dl, HbA1C 7.97 ± 1.72%) were studied. At baseline all subjects underwent baseline clinical examination with blood pressure measurement according to current guidelines, standard laboratory examinations and a 12 leads electrocardiogram. LVH was defined as the presence of a “Sokolow-Lyon” voltage >38 mm and/or a “Cornell voltage QRS duration product” >2440 mm* msec. Treatment was not standardized. Results LVH prevalence was 8.3 % in type 2 DM and 6.4 % in type 1 DM. Patients were followed for 63 ± 27 months (range 1–126). A first non fatal cardiovascular event occurred in 62 patients. Kaplan-Meyer analysis revealed a higher risk of cardiovascular events in patients with LVH both with type 1 and type 2 DM (Log Rank Mantel Cox p<0.01). In Cox analysis, controlling for age, gender, BMI, history of cardiovascular disease, systolic blood pressure, heart rate, total plasma cholesterol, HbA1c, albuminuria and antihypertensive treatment, the presence of LVH was associated with an increased risk of cardiovascular events in all patients (odds ratio 2.96, 95% CI 1.39 to 6.32, p<0.01) and separately in DM type 1 (odds ratio 5.71, 95% CI 1.29 to 25.17, p=0.02) and in type 2 DM (odds ratio 2.92, 95% CI 1.02 to 8.35, p=0.05). Conclusions: Our data demonstrate that in patients with DM the detection of LVH by EKG is associated to an increased risk of cardiovascular events, independently of other risk factors and represent the first demonstration of the prognostic significance of EKG-LVH in patients with type 1 diabetes

AbstractRecent studies have shown that gestational diabetes mellitus (GDM) is associated with an increased risk for cardiovascular disease. GDM has also been shown to be a risk factor for type 2 diabetes (T2DM) after pregnancy. However, there is limited evidence regarding the role of intercurrent T2DM on the relationship between GDM and future CVD. Thus, we investigated the risks of incident cardiovascular events among women with GDM during pregnancy compared to women without GDM and whether the increased CVD risk is dependent on intercurrent development of T2DM. We conducted a population-based retrospective cohort study using the Korean National Health Insurance Service claims database. Outcomes were the first occurrence of any CVD (myocardial infarction, treatment with coronary revascularization, heart failure, and cerebrovascular disease). Cox proportional hazard models were used to assess the association between GDM and incident CVD events, using landmark analysis at 4 years. A total of 1,500,168 parous women were included in the analysis, of which 159,066 (10.60%) had GDM. At a median follow-up of 12.8 years, 13,222 incident cases of total CVD were observed. Multivariable-adjusted hazard ratio for total CVD among women with prior GDM, compared with those without GDM, was 1.08 (95% CI 1.02–1.14). Further classifying GDM by progression to T2DM in relation to total CVD risk indicated a positive association for GDM with progression to T2DM vs no GDM or T2DM (HR 1.74; 95% CI 1.40–2.15), and no statistically significant association for GDM only (HR 1.06; 95% CI 1.00–1.12). GDM with subsequent progression to T2DM were linked with an increased risk of cardiovascular diseases. These findings highlight the need for more vigilant postpartum screening for diabetes and the implementation of diabetes interventions in women with a history of GDM to reduce future CVD risk.

Ayurveda is the science of living being. It begins with right lifestyle including daily and seasonal health regime designed for each individual based upon their nature, constitution, environment and life circumstances. Madhumeha is the subtype of Prameha. Due to resemblance of the feature of Madhumeha with that of DM explained in modern medicine, it is correlated with DM. According to WHO approximately 220 million people worldwide have type 2 diabetes mellitus. It is widely recognized that stress may have negative effects on health and that patients with type 2 diabetes may be at an increased risk. Yoga is an ancient Indian psychological and physical exercise regime and a number of controlled studies exist on the effectiveness of yoga on diabetes mellitus. Yogic practices strengthen and increase the tone of weak muscles and help with conscious control over autonomic function of the body. So, the present study on the role of Yogaabhyas as a lifestyle modification in Madhumeha. Keywords: Madhumeha, type 2 diabetes, asana in diabetes

Introduction: Sodium-glucose cotransporter 2(SGLT2)-inhibitors are new antihyperglycemic agents that have shown a reduction in cardiovascular events in type 2 diabetes mellitus. Recent warnings have been developed about an increased risk of euglycemic and moderate hyperglycemic diabetic ketoacidosis with the use of SGLT2 inhibitors, but its real incidence is not available yet. Case Report: We present a case of DKA with moderate hyperglycemia in a patient treated with metformin and empagliflozin. Conclusion: DKA in patients treated with SGLT2 inhibitors can be presented as euglycemic and moderated hyperglycemia. This special presentation poses a physician’s challenge.

Abstract BackgroundAs a subcomponent of lipoprotein cholesterol (LDL-C), small dense LDL-C (sdLDL-C) have been suggested to be a better predictor of cardiovascular diseases(CVD). This research was to evaluate the predictive of the sdLDL-C in cardiovascular events (CVs) in Chinese elder type 2 diabetes mellitus(DM) patients.MethodsSerum sdLDL-C measured by homogeneous method was compared in 386 consecutive type 2 DM patients between December 2014 and December 2016. Finally, 92 type 2 DM patients had CVs during the 48-month follow-up period. Receiver operating characteristic (ROC) curves were used for assess the predictive value of baseline parameters to major CVs.ResultsNinety-two CVs occurred during the study period.The ROC curve manifested that sdLDL-C in the study population had a matchable discriminatory power (AUC for sdLDL-C was 0.7366, P = 0.003). In addition, kaplan-Meier event-free survival curves displayed a obvious increase of CVs risk for sdLDL-C ≧ 26 mg/dL (log-rank = 9.10,P = 0.003). This phenomenon had analogousresultsin patients who received statins at baseline (log rank = 7.336༌P = 0.007).The study discovered that the increase in HbA1c, glucose, LDL-C, sdLDL-C, non-HDL-C and ApoB and the decrease in ApoA1 were obviously interrelated with heightened CVs risk through Cox regression analysis. Multivariate analysis demonstrated that the increase of sdLDL-C and HbA1c was obviously correlated with CVs. The results of the study indicated that sdLDL-C (per 10 mg/dL) was a increased risk for CVs in the multivariate model (HR 1.281, 95% CI 1.225–16.032; P < 0.01).ConclusionThe consequences demonstrated that sdLDL-C was more effective than RLP-C in predicting the future CVs of Chinese elder type 2 DM patients

The latest studies prove an increased risk of colorectal cancer in patients with type 2 diabetes mellitus. The pathogenetic factors of type 2 diabetes have been recognized as mechanisms of association between these diseases. The objective: to investigate the effects of obesity, hyperinsulinemia, IGF-1 and hyperglycemia on the development of colorectal cancer in patients with type 2 diabetes. Materials and methods. 36 patients were divided into groups: I – healthy (control group), II – patients with type 2 diabetes mellitus, III – patients with colorectal cancer without diabetes, IV – patients with a combination of two diseases. Using the method of enzyme-linked immunosorbent assay were determined levels of insulin and insulin-like growth factor-1 (IGF-1). DM compensation was assessed by the level of glycosylated hemoglobin (HbA1c) that was determined by immuno-exchange chromatography. The data obtained were analyzed using Statistica 12.0 (StatSoft Inc.,USA). Differences between the values in the control and experimental groups were determined by the Student’s t-test. The differences were considered significant at р<0.05. Results. According to the data obtained, colorectal cancer was diagnosed in patients with the age of over 60 years old with obesity. The body mass index (BMI) in patients of all study groups was higher than 30 kg/m2. Patients of group IV with a combination of type 2 diabetes and a circle of rectal cancer had significantly higher BMI compared to the control group (р<0.05). Significant hyperinsulinemia and increased IGF-1 levels were detected in patients in all study groups (р<0.05). Most patients with diabetes in both groups had HbA1c levels higher than 7.5%. Conclusions. Obesity, hyperinsulinemia, increased bioavailability of IGF-1, and hyperglycemia are pathogenetic factors in the risk of colorectal cancer in patients with type 2 diabetes. Patients over the age of 55 with diabetes, obesity, and hyperinsulinemia are advised to be screened for colorectal cancer.

Background: DM is a group of metabolic diseases characterized by hyperglycemia that occurs due to abnormal insulin secretion, insulin action, or both. Symptoms that are complained of in diabetes mellitus sufferers are polydipsia, polyuria, polyphagia, weight loss, and tingling sensation. The oral glucose tolerance test is a test used to diagnose DM when the blood glucose level is less firm, during pregnancy, or to screen for DM or TGT. Leptin is a hormone produced by fat cells that regulate fat storage in the body and adjusts hunger to energy expenditure. Objective: to find out more about the role of leptin on TTGO in people with Type 2 diabetes. Methods: using literature studies from both national and international journals to increase knowledge and understanding of the topics discussed by summarizing the discussion topics and comparing the results presented in the article. Results: Leptin on TTGO examination in individuals with impaired glucose tolerance had a greater chance of becoming diabetes mellitus if there was no intervention in their lifestyle. Conclusion: Leptin plays a role in checking TTGO in people with Type 2 diabetes

Accumulating evidence suggests that gut microbiota plays a crucial role in the development of metabolic diseases, especially type 2 diabetes mellitus (T2DM). The nutrient-rich resource Cornus Fructus (CF) showed curative effects on diabetes mellitus. However, the mechanism underlying its hyperglycemic activity remains obscure. Herein, the antidiabetic potential of four extracts from CF, including saponin (CTS), iridoid glycoside (CIG), tannin (CT), and alcohol extract (CCA) was evaluated in vivo. The results showed that all four extracts could increase the body weight, decrease the blood glucose levels, and elevate the glucose tolerance. Moreover, insulin sensitivity and lipid profile were significantly improved in fed mice. In the [Formula: see text]-diversity index of samples, compared to the DM group, the diversity and richness of gut microbiota in mice to a certain extent were reduced in both CF extracts and Metformin (PC). Among them, there was statistical significance in PC (ACE, [Formula: see text]) and CCA (ACE, [Formula: see text]; chao1: [Formula: see text]). Beta diversity showed the same trend as the UPGMA clustering trees, which revealed that CF extracts could improve intestinal homeostasis in T2DM mice. Also, CF extracts could elevate the production of short-chain fatty acids, as well as regulate the composition of gut microbiota. The key bacteria related to T2DM including Firmicutes, Bacteroides, Lactobacillus, and Clostridium were modulated by metformin and CF. Altogether, CF is a potential nutrient-rich candidate that can be used in functional foods for the treatment of T2DM, and the change of gut microbiota might be a novel mechanism underlying its hyperglycemic activity.
