ReviewCellular and metabolic alterations in the hippocampus caused by insulin signalling dysfunction and its association with cognitive impairment during aging and Alzheimer's disease: studies in animal models.
A growing body of animal and epidemiological studies suggest that metabolic diseases such as obesity, insulin resistance, metabolic syndrome and type 2 diabetes mellitus are associated with the development of cognitive impairment, dementia and Alzheimer's disease, particularly in aging. Several lines of evidence suggest that insulin signalling dysfunction produces these metabolic alterations and underlie the development of these neurodegenerative diseases. ⋯ The comprehensive knowledge of the molecular mechanisms behind the association of metabolic alterations and cognitive impairment could facilitate the early detection of neurodegenerative diseases in patients with metabolic alterations, with treatment that focus on neuroprotection. It could also help in the development of metabolic-based therapies and drugs for using in dementia and Alzheimer's disease patients to alleviate their symptoms in a more efficient and comprehensive way.

Randomized Controlled Trial Multicenter StudyLixisenatide treatment improves glycaemic control in Asian patients with type 2 diabetes mellitus inadequately controlled on metformin with or without sulfonylurea: a randomized, double-blind, placebo-controlled, 24-week trial (GetGoal-M-Asia).
This study assessed the efficacy and safety of the once-daily glucagon-like peptide-1 receptor agonist, lixisenatide, in Asian patients with type 2 diabetes mellitus inadequately controlled on metformin ± sulfonylurea. ⋯ In Asian patients with type 2 diabetes mellitus insufficiently controlled on metformin ± sulfonylurea, lixisenatide significantly improved glycaemic control and was well tolerated during the 24-week study.

Comparative StudyPeroxynitrite and protein nitration in the pathogenesis of diabetic peripheral neuropathy.
Peroxynitrite, a product of the reaction of superoxide with nitric oxide, causes oxidative stress with concomitant inactivation of enzymes, poly(ADP-ribosylation), mitochondrial dysfunction and impaired stress signalling, as well as protein nitration. In this study, we sought to determine the effect of preventing protein nitration or increasing peroxynitrite decomposition on diabetic neuropathy in mice after an extended period of untreated diabetes. ⋯ Peroxynitrite injury and protein nitration are implicated in the development of diabetic peripheral neuropathy. The findings indicate that both structural and functional changes of chronic diabetic peripheral neuropathy can be reversed and provide rationale for the development of a new generation of antioxidants and peroxynitrite decomposition catalysts for treatment of diabetic peripheral neuropathy.

ReviewIncretins: their physiology and application in the treatment of diabetes mellitus.
Therapies targeting the action of incretin hormones have been under close scrutiny in recent years. The incretin effect has been defined as postprandial enhancement of insulin secretion by gut-derived factors. Likewise, incretin mimetics and incretin effect amplifiers are the two different incretin-based treatment strategies developed for the treatment of diabetes. ⋯ Thus, anti-diabetic properties of these two classes of drugs have stimulated substantial clinical interest in the potential of incretin-based therapeutic agents as a means to control glucose homeostasis in T2DM patients. Despite this fact, clinical use of GLP-1 mimetics and DPP-4 inhibitors have raised substantial concerns owing to possible side effects of the treatments involving increased risk for pancreatitis, and C-cell adenoma/carcinoma. Thus, controversial issues in incretin-based therapies under development are reviewed and discussed in this manuscript.

Randomized Controlled TrialGAD-treatment of children and adolescents with recent-onset type 1 diabetes preserves residual insulin secretion after 30 months.
This study aimed to analyse data from two different studies (phase II and phase III) regarding the safety and efficacy of treatment with alum formulated glutamic acid decarboxylase GAD65 (GAD-alum) at 30 months after administration to children and adolescents with type 1 diabetes. ⋯ Treatment with two doses of GAD-alum in children and adolescents with recent-onset type 1 diabetes shows no adverse events and preserves residual insulin secretion.
