Nerve conduction studies, tests of autonomic function and terminal nerve branches, and soleus muscle H reflexes were applied to 60 patients with insulin dependent diabetes mellitus who had no clinical symptoms but abnormal vibratory or temperature perception thresholds indicating subclinical neuropathy. In most patients neurophysiological examination(More)
The brain has long been viewed as an insulin-insensitive organ. Following the demonstration of insulin receptors in the brain, this assumption has been challenged, and a whole new field of research has emerged. Insulin appears to play a role in brain physiology, and disturbances of cerebral insulin signalling and glucose homeostasis are implicated in brain(More)
OBJECTIVE Adipocyte insulin resistance (IR) is a key feature early in the pathogenesis of type 2 diabetes mellitus (T2DM), and although scarce, data in the literature suggest a direct role for iron and iron metabolism-related factors in adipose tissue function and metabolism. Serum ferritin and transferrin were shown to be associated with muscle insulin(More)
OBJECTIVE Microalbuminuria is associated with cardiovascular mortality, particularly among individuals with type 2 diabetes, but the mechanisms underlying this association are not completely understood. Microalbuminuria is known to be associated with cardiovascular autonomic dysfunction (C-AD), and C-AD in turn is associated with cardiovascular mortality.(More)
BACKGROUND In patients with type 1 diabetes mellitus (T1DM), cardiovascular events are more common, and the outcome following a myocardial infarction is worse than in nondiabetic subjects. Ischemic or pharmacological preconditioning are powerful interventions to reduce ischemia reperfusion (IR)-injury. However, animal studies have shown that the presence of(More)
BACKGROUND Cardiovascular morbidity and mortality are higher in patients with schizophrenia than in the general population because the metabolic side-effects of antipsychotics and schizophrenia increase the risk of cardiovascular disease (cvd) and diabetes mellitus type 2 (DM2). The metabolic syndrome is defined in order to discover which patients have a(More)
The efficacy of the neurotrophic peptide ORG 2766 in diabetic patients with polyneuropathy was evaluated in a double-blind, placebo-controlled, multicentre trial. One hundred and twenty four patients were randomised in five groups to receive 0.1, 0.4, 2 or 5 mg ORG 2766 or placebo, once daily, administered subcutaneously 52 weeks. Thermal discrimination(More)
CONTEXT Immune checkpoint blockade is associated with endocrine-related adverse events. Thyroid dysfunction during pembrolizumab therapy, an anti-programmed cell death 1 (PD-1) receptor monoclonal antibody, remains to be fully characterized. OBJECTIVE To assess the incidence and characteristics of pembrolizumab-associated thyroid dysfunction. DESIGN AND(More)
