Microvascular complications (retinopathy, nephropathy, and neuropathy) affect hundreds of millions of patients with type 2 diabetes. They usually affect people with longstanding or uncontrolled disease, but they can also be present at diagnosis or in those yet to have a diagnosis made. The presentation and progression of these complications can lead to loss of visual, renal, and neurologic functions, impaired mobility and cognition, poor quality of life, limitations for employment and productivity, and increased costs for the patient and society...

The deleterious effect of chronic activation of the IL-1β system on type 2 diabetes and other metabolic diseases is well documented. However, a possible physiological role for IL-1β in glucose metabolism has remained unexplored. Here we found that feeding induced a physiological increase in the number of peritoneal macrophages that secreted IL-1β, in a glucose-dependent manner. Subsequently, IL-1β contributed to the postprandial stimulation of insulin secretion. Accordingly, lack of endogenous IL-1β signaling in mice during refeeding and obesity diminished the concentration of insulin in plasma...

Even though ellagic acid has previously been valued in many models of cancer, so far its full mechanistic effect as a natural antiapoptotic agent in the prevention of type 2 diabetes complications has not been completely elucidated, which was the goal of this study. We fed albino rats a high-fat fructose diet (HFFD) for 2 months to induce insulin resistance/type 2 diabetes and then treated the rats with ellagic acid (10 mg/kg body weight, orally) and/or repaglinide (0.5 mg/kg body weight, orally) for 2 weeks...

Carbohydrates include sugars, starches, and dietary fibers. Resistant starches resemble fiber in their behavior in the intestinal tract, and may have positive effects on blood glucose levels and the gut microbiome. Fibers are classified as soluble and insoluble, but most fiber-containing foods contain a mixture of soluble and insoluble fiber. Soluble fiber has been shown to lower low-density lipoprotein cholesterol levels. Many artificial sweeteners and other sugar substitutes are available. Most natural sources of sweeteners also are energy sources...

Chronic hyperglycemia is a hallmark of diabetes mellitus and the main cause of diabetes-associated complications. Increased intracellular glucose levels lead to damaged proteins and in consequence disturb cellular proteostasis. As an important contributor to the maintenance and restoration of proteostasis, autophagy mediates the lysosomal degradation of damaged proteins or entire cellular organelles. In the present study we used the stress-sensitive mev-1 mutant of the nematode Caenorhabditis elegans in order to assess the role of lmp-2, a homologue of the lysosome associated membrane protein type 2A, in the context of glucotoxicity, which was achieved by feeding glucose in a liquid medium...

RTC-1 has recently been identified as a member of a new class of anti-diabetic compounds acting through the inhibition of complex I of the mitochondrial respiratory chain (NADH:ubiquinone oxidoreductase) to improve glucose handling and inhibit weight gain in mice fed a high-fat diet (HFD). The exact mechanism by which the reduced activity of NADH:ubiquinone oxidoreductase, in response to RTC-1, promotes these improved metabolic parameters remains to be established. Through extensive in vitro analysis, new molecular insights into these downstream signalling pathways have been obtained...

INTRODUCTION: Obesity and overweight are an emerging problem in Africa. Obese children are at increased risk of developing hypertension, high cholesterol, orthopaedic problems and type 2 diabetes as well as increased risk of adult obesity. Prevention of childhood overweight and obesity therefore needs high priority. The review approach is particularly useful in establishing whether research findings are consistent and can be generalised across populations and settings. This systematic review aims to assess the magnitude and distribution of overweight and obesity among primary school learners within populations in Africa...

: Studies on the health-promoting effects of lactic acid bacteria (LAB) are numerous, but few provide examples of the relationship between LAB function and culture conditions. We verified the effect of differences in culture conditions on Lactobacillus plantarum OLL2712 (OLL2712) functionality; this strain exhibits anti-inflammatory activity and preventive effects against metabolic disorders. We measured IL-10 and IL-12 production in murine immune cells treated with OLL2712 cells prepared under various culture conditions...

BACKGROUND: Abnormalities in the clinical markers of metabolic syndrome (MS) are associated with the development of cardiovascular disease, type 2 diabetes mellitus, and some cancers. MS prevalence in Korea increased between the mid-1990s and mid-2000s; however, no data on the recent trends of MS prevalence are available. Thus, we aimed to investigate the prevalence of MS, the five components of MS, and the related risk factors in Korean adults by using recent data. METHODS: Data from the Korean National Health and Nutrition Examination Survey conducted between 2008 and 2013 were used...

Aim: Prediabetes and type 2 diabetes are highly prevalent among individuals with serious mental illness and increased by antipsychotic medication. Although widely recommended, many obstacles prevent these patients from obtaining a proper screening for dysglycemia. Currently, glycated hemoglobin (HbA1c), fasting glucose, and 2-hour glucose levels from the oral glucose tolerance test are used for screening prediabetes and type 2 diabetes. The objective of this study was to investigate if HbA1c could be used as the only screening test among individuals with serious mental illness...

Lipoprotein (a) [Lp(a)] is an independent but moderate, predictor for coronary heart disease (CHD) prevalence and severity. Several established and emerging cardiovascular (CV) risk factors including age, gender, ethnicity, smoking, dyslipidemia, hypertension, obesity, type 2 diabetes mellitus, alcohol consumption, arterial stiffness and hyperuricemia have been linked to Lp(a) metabolism. Apart from CHD, Lp(a) has been also associated with non-cardiac vascular diseases and diseases associated with increased CV risk such as chronic kidney disease, metabolic syndrome, non-alcoholic fatty liver disease, erectile dysfunction, obstructive sleep apnea syndrome, inflammatory bowel diseases and human immunodeficiency virus infection...

AIMS/HYPOTHESIS: The mechanisms underlying pancreatic islet mass expansion have attracted considerable interest as potential therapeutic targets to prevent or delay the onset of type 2 diabetes. While several factors promoting beta cell proliferation have been identified, in the context of nutrient excess the roles of glucose or NEFA in relation to insulin resistance remain unclear. Here we tested the hypothesis that glucose and NEFA synergistically and reversibly promote beta cell proliferation in the context of nutrient-induced insulin resistance...

Metformin, a biguanide drug, is emerging as an important treatment option for the prevention or treatment of weight gain, type 2 diabetes mellitus, and the metabolic syndrome in psychiatric patients, especially those who require or receive antipsychotic drugs. Metformin treatment is commonly associated with gastrointestinal adverse effects; the risk of these is reduced by gradual dose uptitration, administration of the drug with meals, and use of a time-release formulation. Lactic acidosis, a potentially fatal complication of biguanide therapy, is very rare with metformin; the risk can be reduced by avoidance of its prescription in patients with impaired renal function, impaired liver function, cardiac failure, and certain other conditions...

BACKGROUND: Studies evaluating the relationship between soluble transferrin receptor (sTfR), a biomarker inversely related to body iron stores, and risk of type 2 diabetes mellitus (T2DM) are scarce and inconclusive. Furthermore, sTfR concentrations have been observed to be significantly higher in obese than in non-obese individuals. Therefore, the aim of the present study was to assess the relationship between sTfR and the risk of T2DM in obese and non-obese subjects. DESIGN: A nested case-control study of 153 cases of newly diagnosed diabetic subjects, 73 obese and 80 non-obese, and 306 individually matched-controls, 138 obese and 166 non-obese, who did not develop T2DM for a median 6-year follow-up (interquartile range: 3...

A typical hallmark of diabetic kidney disease (DKD) is an excessive deposition of extracellular matrix (ECM) in the glomerulus and renal tubulointerstitium, leading to glomerulosclerosis and tubular interstitial fibrosis. Src homology 2 domain-containing inositol 5'-phosphatase (SHIP) is a negative regulator of the phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) signaling. Here, we investigated the effect of SHIP on ECM deposition in diabetic mice and high glucose-stimulated human renal tubular epithelial cells (HK2 cells)...

SCOPE: In this study, we investigated the effect of aged garlic extract (AGE) on the high level of blood glucose in Tsumura Suzuki Obese-Diabetes (TSOD) mice. METHODS AND RESULTS: TSOD mice were fed standard diet with or without 2% AGE for 19 weeks. AGE treatment lowered the blood glucose level and significantly reduced the plasma level of glycated albumin in TSOD mice as compared with those without AGE treatment. In addition, AGE treatment increased the level of phosphorylated AMP-activated protein kinase (AMPK) in the adipose tissue, liver and muscle that played an important role in the maintenance of insulin sensitivity...

Recent studies have demonstrated the benefits of osteocalcin (OCN) on glucose homeostasis and metabolic dysregulation. However, its role in body composition and vascular function remains unknown. This study was designed to examine changes in metabolic parameters and body composition as well as arterial stiffness after OCN treatment in type 2 diabetic rats. Adult male Sprague Dawley (SD) rats were fed chow or high fat diet (HFD) for 8 weeks, and then diabetes was induced with an injection of low-dose streptozotocin (STZ) and treated daily with intraperitoneal injections of OCN for 12 weeks...

BACKGROUND: Lactation may protect women with previous gestational diabetes mellitus (GDM) from developing type 2 diabetes, but the results of existing studies are inconsistent, ranging from null to beneficial. We aimed to conduct a systematic review to gather available evidence. METHODS: Databases MEDLINE, CINAHL, PubMed and EMBASE were searched on 15 December 2015 without restriction of language or publication year. A manual search was also conducted. We included observational studies (cross-sectional, case-control and cohort study) with information on lactation and type 2 diabetes incidence among women with previous GDM...
