Publication date: Available online 6 December 2019Source: Diabetes &Metabolic Syndrome: Clinical Research &ReviewsAuthor(s): Biswapriya B. Misra, Anoop MisraAbstractT2DM, variously known as diabetes mellitus type 2, adult-onset diabetes; noninsulin-dependent diabetes mellitus (NIDDM) is a global silent killer, with> 450 million adults affected worldwide. A diverse array of non-modifiable risk factors such as family history, age (>45 yrs), race/ethnicity, and history of gestational diabetes) and modifiable risk factors such as physical inactivity, high body fat or body weight, high blood pressure and high cholesterol for progression of prediabetes to T2DM. Given, the modern world human population is constantly exposed to multiple stressors in the form of physical (i.e., sound) and chemical environment (i.e., diet, pollutants), industrialization and modernization has led to exposomal correlation with T2DM. Over the past decade, there have been emerging reports on correlation of levels of persistent organic pollutants (POPs), phthalates, antibiotics, drugs, air pollution, pesticides, and heavy metals with T2DM. In this review, we discuss the chemical exposome that has been associated with T2DM; the tools and approaches to capture this chemical exposome and future opportunities and challenges in this exciting area of research. We further provide a window of thoughts, whether omics technologies can help fill in the gaps to help provide high throughput exposomics data...

Authors: Gao RY, Hsu BG, Wu DA, Hou JS, Chen MC Abstract Background: Fibroblast growth factor 21 (FGF21) acts as a potent metabolic regulator. Serum FGF21 levels were significantly higher in obesity and type 2 diabetes mellitus (T2DM) populations. The aim of this study was to evaluate the relationship between serum FGF21 levels and metabolic syndrome (MetS) in T2DM patients. Methods: Fasting blood samples were obtained from 126 T2DM patients. MetS and its components were defined according to the diagnostic criteria from the International Diabetes Federation. Serum FGF21 concentrations were measured using a comm...

Background and Aims: Type-2 diabetes mellitus (T2DM) and metabolic syndrome (MS) are multifactorial and multigenic diseases and hallmarks for atherosclerosis and stroke. Characteristics of these diseases include glucose intolerance, insulin resistance, hypertension, and disorders in triglyceride and cholesterol metabolism. Despite intensive research in this area, major factors liable for T2DM and MS and in turn for treatment are still elusive.

In conclusion, the impaired in situ activity of RyR2 may also account for the poor overall cardiac outcome reported in MetS patients; hence, the SERCA pump and RyR2 are both attractive potential targets for future therapies. Introduction Metabolic syndrome (MetS) is a cluster of biochemical and physiological risk factors for cardiovascular disease and diabetes mellitus type 2 (DM2); it represents a severe public health problem around the world (Alberti et al., 2009). Risk factors for MetS include obesity (particularly central obesity), elevated triglyceride (TG) levels, low high-density lipoprotein cholesterol (HDL...

The prevalence of hypertension, type 2 diabetes mellitus (DM2) and the metabolic syndrome continues to increase in Latin America, while the rates of diagnosis, treatment and control of these disorders remain low. The frequency of the risk factors that constitute the metabolic syndrome and are associated with an increased risk of cardiovascular disease has not diminished since the publication of the previous consensus. This document discusses the socioeconomic, demographic, environmental and cultural characteristics of most associated Latin American countries and partially explains the lack of better results in improving cl...

We examined the effects of the independent and combined effects of Zataria Multiflora supplementation and circuit resistance training (CRT) on selected adipokines among postmenopausal women. Forty-eight postmenopausal women were divided into four groups: Exercise (EG, n = 12), Zataria Multiflora (ZMG, n = 12), exercise and Zataria Multiflora (ZMEG, n = 12), and control (CG, n = 12). Participants in experimental groups either performed CRT (3 sessions per week with intensity at 55% of one-repetition maximum) or supplemented with Zataria Multiflora (500 mg every day after breakfast with 100 ml of water), or their combination...

This study aimed to compare the effect of high-intensity interval training (HIIT) with moderate-intensity continuous training (MCT) on endothelial function, oxidative stress and clinical fitness in patients with type 1 diabetes. Thirty-six type 1 diabetic patients (mean age 23.5 ± 6 years) were randomized into 3 groups: HIIT, MCT, and a non-exercising group (CON). Exercise was performed in a stationary cycle ergometers during 40 min, 3 times/week, for 8 weeks at 50–85% maximal heart rate (HRmax) in HIIT and 50% HRmax in MCT. Endothelial function was measured by flow-mediated dilation (FMD) [endothelium-depende...

Conclusion Activation of the Nrf2-dependent antioxidant system plays an important role in cell defense against oxidative stress damage, whereas the insufficiency of the Nrf2 system is associated with multiple aspects of the genesis and progression of metabolic diseases, posing a great risk to the cardiovascular system (Figure 1). The systemic increase of Nrf2 activity by several activators may be beneficial in the treatment of metabolic diseases. In addition, selective upregulation of Nrf2 genes may represent a potential therapy in obesity, diabetes and atherosclerosis. Looking to the future, experimental research that el...

Conclusions: Our study shows that a higher burden of liver steatosis seems to be associated with less severe stroke and better functional outcome after ischemic stroke or TIA. Introduction Non-alcoholic fatty liver disease (NAFLD) is a spectrum of diseases from simple steatosis to steatohepatitis with varying degree of fibrosis, and liver cirrhosis (1, 2). NAFLD is becoming the most common chronic liver disease worldwide including Korea, affecting approximately 25% of the general population (3, 4). NAFLD is closely associated with obesity, insulin resistance, and type 2 diabetes mellitus, and is even recognized as ...

Abstract Obesity is a risk factor for metabolic syndrome, dyslipidemia, hypertension, insulin resistance, type 2 diabetes mellitus, and cardiovascular disease. However, obesity is not a homogenous state and not all subjects in an obese population are at an increased risk for metabolic abnormalities. Thus, obesity types can be subdivided into metabolically healthy obesity (MHO) and metabolically unhealthy obesity (MUO) according to metabolic status. Body minerals are important and are involved in various metabolic processes that may be related to obesity. Thus, this study determined whether hair mineral concentrati...
