BACKGROUND: High levels of circulating GLP-1 are associated with severity of sepsis in critically ill non-diabetic patients. Whether type 2 diabetes (T2D) patients display different activation of the endogenous GLP-1 system during sepsis and whether it is affected by diabetes related metabolic parameters is not known. METHODS: Serum levels of GLP-1 (total and active forms) and its inhibitor enzyme sDPP-4 were determined by ELISA on admission and after 2-4 days in 37 sepsis patients with (n=13) and without T2D (n=24) and compared to normal healthy controls (n=25)...

Despite a clear association between type 2 diabetes (T2D) and fracture risk, the pathogenesis of bone fragility in T2D has not been clearly elucidated. Insulin resistance is the primary defect in T2D. Insulin signalling regulates both bone formation and bone resorption, but whether insulin resistance can affect bone has not been established. On the other hand, evidence exists that bone might play a role in the regulation of glucose metabolism. This article reviews the available experimental and clinical evidence on the interplay between bone and insulin resistance...

The incidence of obesity and metabolic disease, such as type 2 diabetes mellitus (T2D), are rising globally. Dietary lipid over-supply leads to lipid accumulation at ectopic sites, such as skeletal muscle. Ectopic lipid storage is highly correlated with insulin resistance and T2D, likely due to a loss of metabolic flexibility - the capacity to switch between fat and glucose oxidation upon insulin stimulation - and cellular dysfunction because of lipotoxicity. However, muscle lipid levels are also elevated in endurance trained athletes, presenting a paradoxical phenotype of increased intramuscular lipids along with high insulin sensitivity - the "athletes' paradox"...

BACKGROUND/OBJECTIVE: After digestion, dietary triacylglycerol stimulates incretin release in humans, mainly through generation of 2-monoacylglycerol, an agonist for the intestinal G protein-coupled receptor 119 (GPR119). Enhanced incretin release may have beneficial metabolic effects. However, dietary fat may promote weight gain and should therefore be restricted in obesity. We designed C4-dietary oil (1,3-di-butyryl-2-oleoyl glycerol) as a 2-oleoyl glycerol (2-OG)-generating fat type, which would stimulate incretin release to the same extent while providing less calories than equimolar amounts of common triglycerides, e...

The evidence on the association between long-term low-carbohydrate, high-fat and high-protein diets and type 2 diabetes (T2D) is controversial. Until now, data is limited for Chinese populations, especially in considering the influence of extra energy intake. In this paper, we aimed to investigate the association of low-carbohydrate, high-fat and high-protein diets with type 2 diabetes (T2D) risk in populations consuming extra calories and those with normal caloric intake, We also determined whether the association is mediated by insulin resistance (IR) or β-cell dysfunction...

AIMS/ INTRODUCTION: Higher hedonic hunger has been observed in obese individuals compared to those without obesity, but little is known about its association with glycemic management. We aimed to examine the association between hedonic hunger and glycemic control in non-obese and obese patients with type 2 diabetes (T2D). METHODS: Between April and November 2016, a total of 211 T2D patients who underwent comprehensive diabetes assessments at a university-affiliated hospital were recruited into two groups according to body mass index (BMI): non-obese (BMI) = 18...

INTRODUCTION: A basal-bolus insulin regimen is needed to achieve glycated hemoglobin A1c (HbA1c) below 7.0% in people with type 1 (T1D) or type 2 (T2D) diabetes who have significant loss of beta-cell function. Nonadherence to therapy is common and negatively affects the ability to reach treatment goals. We examined patient assessment of a new, wearable mealtime insulin-delivery system (patch) relative to their current mealtime insulin-delivery system (syringe, pen, or pump). The patch is designed to deliver only boluses of fast-acting insulin (no basal insulin), mechanically controlled by the patient...

Modifications of the interactions between endoplasmic reticulum (ER) and mitochondria, defined as mitochondria-associated membranes (MAMs), were recently involved in the control of hepatic insulin action and glucose homeostasis, but with conflicting results. Whereas skeletal muscle is the primary site of insulin-mediated glucose uptake and the main target for alterations in insulin resistant states, the relevance of MAM integrity in muscle insulin resistance is unknown. Deciphering the importance of MAMs on muscle insulin signaling could help to clarify this controversy...

Context: Carnitine and its metabolites are centrally involved in fatty acid metabolism. While elevated circulating concentrations have been observed in obesity and insulin resistance, prospective studies examining whether these metabolites are associated with incident type 2 diabetes mellitus (T2D) are sparse. Objective: We performed a comprehensive evaluation of metabolites along the carnitine pathway in relation to incident T2D. Design: A total of 2519 patients (73...

Diabetes is a global epidemic and a leading cause of death with more than 422 million patients worldwide out of whom around 392 million alone suffer from type 2 diabetes (T2D). Sodium-glucose cotransporter 2 inhibitors (SGLT2i) are novel and effective drugs in managing glycemia of T2D patients. These inhibitors gained recent clinical and basic research attention due to their clinically observed cardiovascular protective effects. Although interest in the study of various SGLT isoforms and the effect of their inhibition on cardiovascular function extends over the past 20 years, an explanation of the effects observed clinically based on available experimental data is not forthcoming...

Results from previous prospective studies assessing the relation between adiponectin and type 2 diabetes (T2D) were not entirely consistent, and evidence in Chinese population is scarce. Moreover, the last meta-analysis did not examine the impact of metabolic variables on the adiponectin-T2D association. Therefore, we prospectively evaluated the adiponectin-T2D association among 571 T2D cases and 571 age-sex-matched controls nested within the Singapore Chinese Health Study (SCHS). Furthermore, we conducted an updated meta-analysis by searching prospective studies on Pubmed till September 2016...

Ileal interposition (IT) surgery delays the onset of diabetes in a rat model of type-2 diabetes (UCD-T2DM). Here, to gain a deeper understanding of the molecular events underlying the effects of IT surgery, we examined the changes in the proteome of 4 white adipose depots (retroperitoneal, mesenteric, inguinal, and epididymal), and plasma free fatty acid profile in pre-diabetic rats 1.5 months following IT or sham surgery. The IT-mediated changes were exerted mainly in mesenteric fat, and spanned from delayed adipocyte maturation to a neuroendocrine remodeling...

INTRODUCTION: Islet transplantation (IT) can treat patients with severely unstable type 1 diabetes. Pre-hepatic kinetics of insulin-secretion (ISec) in two phases can be calculated by C-peptide levels during meal tests. We propose to describe insulin secretion profile after a Mixed-Meal Tolerance Test (MMTT) in IT patients and to determine whether the calculated indexes of ISec can predict graft outcome. METHODS: We analyzed 34 MMTT among 11 patients who received an IT between 2011 and 2016 and compared them to healthy controls (C) and type 2 diabetic (T2D) patients...

Althoughdiabetes mellitus (DM) is reported as an independent risk factor for colorectal cancer (CRC) in many researches, the underlying pathophysiology is still unclear. We investigated the differentiallyexpressedgenes (DEGs)for the diabetes and CRC to reveal the underlying pathophysiological association between the type 2-diabetic (T2D) and CRC. Gene expression profiles for T2D (GSE55650), CRC (GSE8671) and Metformin treated cell lines (GSE67342) were downloaded from GEO database. The DEGs between T2D samples and their control samples were identified with t-test and variance analysis...

Insulin resistance is often characterized as the most critical factor contributing to the development of (T2D) type 2 diabetes. MicroRNAs (miRNAs) are endogenous non-coding short single-stranded RNAs that function as negative regulators in many physiological and pathological processes. The objective of this study was to evaluate the roles of miR-125b in the regulation of insulin sensitivity in hepatocytes. We found that hepatic miR-125b levels were significantly increased in the patients with type 2 diabetes, high fat diet (HFD) mice, ob/ob and db/db mice...
