Methods. A substudy of a double-masked, randomized, cross-over ...

Gastric bypass surgery causes resolution of type 2 diabetes (T2DM), which has led to the hypothesis that upper gastrointestinal (UGI) tract diversion, itself, improves glycemic control. The purpose of this study was to determine whether UGI tract bypass without gastric exclusion has therapeutic effects in patients with T2DM. We performed ...

Elevated plasma concentrations of TNF receptors 1 and 2 (TNFR1 and TNFR2) predict development of ESRD in patients with type 2 diabetes without proteinuria, suggesting these markers may contribute to the pathogenesis of renal decline. We investigated whether circulating markers of the TNF pathway determine GFR loss among patients with ...

Background:Puberty is a so-called critical period for overweight development and is characterized by physiological insulin resistance during mid-puberty. This study addressed the hypothesis that habitual consumption of a diet inducing higher levels of postprandial glycemia or insulinemia during puberty may have an unfavorable effect on the body composition in young ...

Aims:  Using the HbA(1c) level to define diabetes has several advantages and these advantages also apply to define a high-risk group. However, the risk of diabetes increases as HbA(1c) increases and a certain degree of arbitrariness in the cut-off for the high risk group is unavoidable. The aim of this ...

AIMS/HYPOTHESIS: Pharmacological augmentation of glucagon-like peptide 1 receptor signalling by dipeptidyl peptidase 4 (DPP-4) inhibition reduced intestinal lipoprotein secretion in experimental studies, suggesting that DPP-4 inhibitors may ameliorate dyslipidaemia and thus reduce cardiovascular risk in patients with type 2 diabetes. We assessed the effects of alogliptin (Alo) and Alo co-administered ...

Context:Aging is associated with deteriorating glucose tolerance. Studies assessing glucose tolerance and subsequent insulin and incretin hormone release often fail to take into account the rate of gastric emptying when evaluating these responses.Objective:Our objective was to determine the comparative effects of variations in the small intestinal glucose load on the ...

We sought to determine whether the blood pressure (BP) levels at which cardiovascular (CV) protection is achieved differ between diabetic and nondiabetic patients from the ONTARGET (ONgoing Telmisartan Alone and in combination with Ramipril Global Endpoint Trial). Greater absolute benefits of BP reductions have been claimed for diabetic as compared ...

We showed recently that sustained natriuresis in type 1 diabetic dogs was attributed to the decrease in insulin rather than the hyperglycemia alone. The sodium-retaining action of insulin appeared to require hyperglycemia, and it completely reversed the diabetic natriuresis and diuresis. This study tested whether the sodium-retaining effect was attributed ...

Background: Despite numerous studies of diabetes mellitus type II (DM-II) in schizophrenia and schizoaffective disorder, there have been no studies on the glycemic effects of switching patients with long-standing symptomatic DM-II from their current antipsychotic regimen to ziprasidone. Methods: An open-label, prospective inpatient study was conducted with 26 suboptimally responding ...

METHODS: Correlations between HbA1c or glycated albumin (GA) and estimated glomerular filtration ...

Background- In coronary artery disease patients, enhanced external counterpulsation (EECP) improves peripheral arterial function and nitric oxide (NO) bioavailability, which have been implicated in the pathogenesis of abnormal glucose tolerance (AGT). We sought to evaluate the effects of EECP on outcomes of arterial function, glucose tolerance, and skeletal muscle morphology ...

Children from diabetic pregnancies have a greater incidence of Type 2 diabetes. Our objective was to determine if exposure to mild-moderate hyperglycemia, modeling managed diabetic pregnancies, affects fetal β-cell function. In sheep fetuses β-cell responsiveness was examined after two weeks of sustained hyperglycemia with 3 pulses/day, mimicking postprandial excursions, and ...

Aims. Dipeptidyl peptidase (DPP)-4 in responsible for incretin degradation and some observations suggest that DPP-4 activity is increased in type 2 diabetes (T2D).

BACKGROUND: Postprandial hypoglycaemia is a severe complication of Roux-en-Y gastric bypass (RYGBP). Acarbose, an α-glucosidase inhibitor (AGI), is employed in its treatment. Several studies have shown that AGIs increase the postprandial levels of glucagon-like peptide 1 (GLP-1). However, an excessive level of GLP-1 is one of the factors involved in ...

One of the biggest challenges of premature birth is acute hypoxia. Hypothermia during acute hypoxic periods may be beneficial. We hypothesized that prevention of hypothermia during neonatal hypoxia disrupts glucose homeostasis and places additional metabolic challenges on the neonate. Pups at PD2 and PD8 were exposed to 8% O2 for ...

The objective was to compare weight loss and change in body composition in obese subjects with and without type 2 diabetes mellitus during a very-low-calorie diet (VLCD) program. Seventy weight-matched subjects with diabetes or normal fasting glucose (controls) participated in a 24-week VLCD study. Primary end points were changes in ...

Objective: Black persons have higher hemoglobin A1c (HbA1c) values than white persons with similar blood glucose levels, but these data have been derived from populations with variable glycemic status and largely unknown familial history of diabetes. We therefore investigated racial disparities in HbA1c among nondiabetic persons with similar parental history ...

Red ginseng (RG, Panax ginseng C.A. Meyer) is one of the widely used herbs for treating type 2 diabetes mellitus (DM). However, no systematic review of the effectiveness of RG for type 2 DM is available. This systematic review aimed to evaluate the current evidence for the effectiveness of RG ...

Insulin therapy is commonly associated with weight gain. The timing of prandial insulin administration may enhance its efficacy/safety and maintain effective weight control. This study examined the effect of postprandial vs. preprandial insulin glulisine on weight gain and glycaemic control in type 2 diabetes patients taking basal insulin. This was ...

BACKGROUND: Roux-en-Y gastric bypass (RYGB) results in profound weight loss and resolution of type 2 diabetes mellitus (T2DM). The mechanism of this remarkable transition remains poorly defined. It has been proposed that endotoxin (lipopolysaccharide [LPS]) sets inflammatory tone, triggers weight gain, and initiates T2DM. Because RYGB may diminish LPS from ...
