Background: Lifestyle interventions have been shown to improve physical function over the short term; however, whether these benefits are sustainable is unknown. The long-term effects of an intensive lifestyle intervention on physical function were assessed using a randomized post-test design in the Look AHEAD trial. Methods: Overweight and obese (BMI ≥25 kg/m 2) middle-aged and older adults (aged 45-76 years at enrollment) with type 2 diabetes enrolled in Look AHEAD, a trial evaluating an intensive lifestyle intervention (ILI) designed to achieve weight loss through caloric restriction and increased physical activity compared to diabetes support and education (DSE), underwent standardized assessments of performance-based physical function including a 4- and 400-m walk, lower extremity physical performance (expanded Short Physical Performance Battery, SPPBexp), and grip strength approximately 11 years post-randomization and 1...

OBJECTIVE: The Williams-Beuren syndrome (WS) is associated with impaired glucose metabolism (IGM) early in adulthood. However, the pathophysiology of IGM remains poorly defined, due to the lack of longitudinal studies investigating the contribution of β-cell dysfunction and impaired insulin sensitivity. This study aimed at assessing incidence of IGM and the underlying mechanisms in WS adults. METHODS: This observational, longitudinal (5-year), cohort study enrolled thirty-one consecutive WS subjects attending a tertiary referral center...

Electrical stimulation (ES) has been tested for decades to improve chronic wound healing. However, uncertainty remains on the magnitude of the efficacy and on the best applicable protocol. We conducted an effect size meta-analysis to assess the overall efficacy of ES on wound healing, to compare the efficacy of the different modalities of electrical stimulation, and to determine whether efficacy differs depending on the wound etiology, size and age of the chronic wound. Twenty-nine randomized clinical trials with 1510 patients and 1753 ulcers were selected...

Type-1 Diabetes (T1D) is a devastating autoimmune disorder which results in the destruction of beta cells within the pancreas. A promising treatment strategy for T1D is the replacement of the lost beta cell mass through implantation of immune-isolated microencapsulated islets referred to as the bioartificial pancreas. The goal of this approach is to restore blood glucose regulation and prevent the long-term comorbidities of T1D without the need for immunosuppressants. A major requirement in the quest to achieve this goal is to address the oxygen needs of islet cells...

Hyperglycemia-induced oxidative stress is usually found in diabetic condition. 3-hydroxy-3-methylglutaryl coenzyme-A (HMG-CoA) reductase inhibitors, statins, are widely used as cholesterol-lowering medication with several "pleiotropic" effects in diabetic patients. This study aims to evaluate whether the protective effects of atorvastatin and insulin on renal function and renal organic anion transporter 3 (Oat3) function involve the modulation of oxidative stress and pancreatic function in type 1 diabetic rats...

Advanced glycation end products (AGEs) are adducts formed on proteins by glycation with reducing sugars, such as glucose, and tend to form and accumulate under hyperglycemic conditions. AGE accumulation alters protein function and has been implicated in the pathogenesis of many degenerative diseases such as diabetic complications. AGEs have also been shown to promote the production of pro-inflammatory cytokines, but the roles of AGEs in inflammasome signaling have not been explored in detail. Here, we present evidence that AGEs attenuate activation of the NLRP3 inflammasome in bone marrow-derived macrophages (BMDMs) as determined by caspase-1 processing and interleukin-1β production...

Nicotine, the major component of cigarettes, has demonstrated conflicting impact on the immune system: some authors suggest that increases pro-inflammatory cytokines and provokes cellular apoptosis of neutrophils, releasing intracellular components that act as auto-antigens; others claimed that nicotine has a protective and anti-inflammatory effects, especially by binding to α7 subunit of nicotinic acetylcholine receptors. The cholinergic pathway contributes to an anti-inflammatory environment characterized by increasing T regulatory cells response, down-regulating of pro-inflammatory cytokines and a pro-inflammatory cells apoptosis...

Chronic oxidative stress fuels pathogenesis of a large set of diseases. Oxidative stress is the cause and consequence of numerous diseases including type 1 diabetes mellitus (T1DM), in which there is selective destruction of insulin producing pancreatic β-cells. Studies have documented that hyperglycemia produces profound stress. In vivo production of numerous reactive oxygen, nitrogen, chlorine species and lipid/sugar oxidation products are result of persistent hyperglycemia. Post-translational modifications by reactive species may create new antigenic epitopes and play a role in the development of autoimmune response...

Poor health is widely recognized as a consequence of social disadvantage, but health problems may also help transmit social disadvantage over time and generations. Experimentally assigned health exposures, namely those tested in randomized controlled trials, may provide opportunities to estimate the causal effects of health on socioeconomic status (SES). We revisit data from the Diabetes Control and Complications Trial, a randomized controlled trial of glucose control therapy in Type 1 diabetic patients, and use treatment assignment as an instrument for health status to test the causal effect of treatment-related health improvement on subsequent SES measured during the trial's follow-up study, the Epidemiology of Diabetes Interventions and Complications study...

Type 2 diabetes mellitus (T2DM) is a risk factor for Alzheimer disease (AD). Previous studies have shown that the incretin hormones glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) that have anti-diabetic properties show very promising effects in animal models of AD. Glucagon (Gcg) is a hormone and growth-factor, and the Gcg receptor is expressed in the brain. Here we test the effects of a triple receptor agonist (TA), which activates GIP-1, GIP and glucagon receptors at the same time...
