INTRODUCTION: Evaluation of interventions can help to close the gap between research and practice but seldom takes place during implementation. Using the RE-AIM framework, we conducted a formative evaluation of the first year of the Intermountain Healthcare Diabetes Prevention Program (DPP). METHODS: Adult patients who met the criteria for prediabetes (HbA1c of 5.70%-6.49% or fasting plasma glucose of 100-125 mg/dL) were attributed to a primary care provider from August 1, 2013, through July 31, 2014...

BACKGROUND: AMP-activated protein kinase (AMPK) is a protein kinase that maintains homeostasis in cells and organs. As a master regulator of metabolism, AMPK coordinates many metabolic reactions. AMPK is a key factor in diabetes and metabolic syndrome associated with dysregulation of the metabolic status. Recently, AMPK has also attracted attention as a tumor suppressor. The aim of this article is to discuss about the role of AMPK in diabetes as well as cancer and to evaluate its effectiveness in treatment and prevention of these diseases...

BACKGROUND: Metformin, the eldest and most widely used glucose lowering drug, is likely to be effective also on cardiac and vascular disease prevention. Nonetheless, uncertainty still exists with regard to its effects on the cardiovascular system as a whole and specifically on the myocardium, both at the organ and cellular levels. METHODS: We reviewed the available data on the cardiac and vascular effects of metformin, encompassing both in vitro, either tissue or isolated organ, and in vivo studies in experimental animals and humans, as well as the evidence generated by major clinical trials...

BACKGROUND: Preventing diabetes before pregnancy may be important to improve maternal and infant outcomes. Although the preconception period is a crucial time to focus on chronic disease prevention, little is known about preventive services for reproductive-aged women at risk of developing diabetes. METHODS: Using electronic health record data from patients at Kaiser Permanente Northern California, we identified 21,965 nonpregnant women aged 18 to 44 with incident prediabetes (PDM; fasting plasma glucose [FPG] = 100-125 or glycated hemoglobin A1c = 5...

Metformin is the most frequently used drug for the treatment of type-II diabetes. As metformin has been reported to cross the blood-brain barrier, brain cells will encounter this drug. To test whether metformin may affect the metabolism of neurons, we exposed cultured rat cerebellar granule neurons to metformin. Treatment with metformin caused a time- and concentration-dependent increase in glycolytic lactate release from viable neurons as demonstrated by the three-to fivefold increase in extracellular lactate concentration determined after exposure to metformin...

Metformin prevents weight gain in patients with type 2 diabetes (T2D). However, the mechanisms involved are still unknown. In this post-hoc analysis of the HOME trial, we aimed to determine whether metformin affects energy intake. Patients with T2D were treated with 850 mg metformin or placebo (1-3 times daily) added to insulin for 4.3 years. Dietary intake was assessed at baseline, after 1 year and after 4.3 years, according to the dietary history method. Of the 310 included participants, 179 completed (93 placebo, 86 metformin) all three dietary assessments...

Prediabetic individuals are characterized by high levels of insulin, an anabolic hormone having an important role in the maintenance of glucose homeostasis. However, insulin has also been found to increase the growth of certain bacteria which form the non-butyrate producing part of the gut microbiome. The gut microbiome is recently in focus for its strong association with many chronic diseases such as type 2 diabetes mellitus and obesity. Metformin, a widely popular anti-diabetic medication has been shown to prevent weight gain in many trials...

PURPOSE: Type 2 diabetes mellitus (T2DM) patients treated with metformin are predisposed to develop contrast-induced nephropathy (CIN) after received emergency contrast-enhanced computed tomography (CT) examination. We evaluated the protective effects of alprostadil on CIN in T2DM patients treated with metformin after contrast media (CM) administration. METHODS: In this single-institution, single-blind, superiority trial, we randomly assigned 451 T2DM patients taking metformin and underwent emergency contrast-enhanced CT examination to either the alprostadil group (227 patients) receiving alprostadil or the control group (224 patients) without alprostadil...

Polycystic ovary syndrome (PCOS) is the most prevalent endocrinopathy among women during reproductive age. PCOS is characterised by hyperandrogenaemia, hyperinsulinaemia, and deranged adipokines secretion from the adipose tissue. In addition to the reduced insulin sensitivity, PCOS women exhibit β-cell dysfunction as well. Low birth weight and foetal exposure to androgens may contribute to the development of the PCOS phenotype during life. Further metabolic complications lead to dyslipidaemia, worsening obesity and glucose tolerance, high prevalence of metabolic syndrome, and greater susceptibility to diabetes...

The FATZO/Pco mouse is the result of a cross of the C57BL/6J and AKR/J strains. The crossing of these two strains and the selective inbreeding for obesity, insulin resistance and hyperglycemia has resulted in an inbred strain exhibiting obesity in the presumed presence of an intact leptin pathway. Routinely used rodent models for obesity and diabetes research have a monogenic defect in leptin signaling that initiates obesity. Given that obesity and its sequelae in humans are polygenic in nature and not associated with leptin signaling defects, the FATZO mouse may represent a more translatable rodent model for study of obesity and its associated metabolic disturbances...

Omentin-1, also known as intelectin-1, is a recently identified novel adipocytokine of 313 amino acids, which is expressed in visceral (omental and epicardial) fat as well as mesothelial cells, vascular cells, airway goblet cells, small intestine, colon, ovary, and plasma. The level of omentin-1 expression in (pre)adipocytes is decreased by glucose/insulin and stimulated by fibroblast growth factor-21 and dexamethasone. Several lines of experimental evidence have shown that omentin-1 plays crucial roles in the maintenance of body metabolism and insulin sensitivity, and has anti-inflammatory, anti-atherosclerotic, and cardiovascular protective effects via AMP-activated protein kinase/Akt/nuclear factor-κB/mitogen-activated protein kinase (ERK, JNK, and p38) signaling...

The Canadian First Nations population is disproportionately burdened by diabetes and diabetes complications. Body weight management is purported to be important in the prevention and management of diabetes. In this study, we sought to describe weight change in a First Nation cohort according to diabetes status and management. Study data were from two diabetes screening studies in Sandy Bay First Nation in Manitoba, Canada, collected in 2002/2003 (baseline) and 2011/2012 (follow-up). The cohort was composed of respondents to both screening studies (n=171)...

Ischemic strokes are major causes of death and disability. Searching for potential therapeutic strategies to prevent and treat stroke is necessary, given the increase in overall life expectancy. Epidemiological reports indicate that metformin is an oral antidiabetic medication that can reduce the incidence of ischemic events in patients with diabetes mellitus. Its mechanism of action has not been elucidated, but metformin pleiotropic effects involve actions in addition to glycemic control. AMPK activation has been described as one of the pharmacological mechanisms that explain the action of metformin and that lead to neuroprotective effects...

Oral hypoglycemic drugs for type 2 diabetes aim at preventing the metabolic effects of hyperglycemia and cardiovascular (CV) events. The evidence of the possible CV risk related to the prescription of some antidiabetic drugs prompted regulatory agencies to require safety studies. This review provides an updated analysis of CV safety profiles for antidiabetic drugs used for the treatment of patients with high CV risk.The most recent studies analyze different aspects of CV morbidity, such as ischemic events, heart failure and arrhythmia, and their interactions with hyperglycemia...

Postprandial hypertriglyceridemia is a potential target for cardiovascular disease prevention in patients with diabetic dyslipidemia. Metformin has been reported to reduce plasma triglyceride concentrations in the postprandial states. However, little is known about the mechanisms underlying the triglyceride-lowering effect of metformin. Here, we examined the effects of metformin on lipid metabolism after olive oil-loading in 129S mice fed a high fat diet for three weeks. Metformin administration (250 mg/kg) for one week decreased postprandial plasma triglycerides...

Perivascular adipose tissue dysfunction induced by high-fat feeding leads to alterations in the modulation of inflammation, contractile activity of the vascular smooth muscle and endothelial function, all risk factors in the development of hypertension. Metformin, an activator of AMP-activated protein kinase (AMPK), is currently the first-line drug treatment for type 2 diabetes (T2DM) and metabolic syndrome. Besides its glucose-lowering effect, there is an interest in actions of this drug with potential relevance in cardiovascular diseases...
