The incretin effect in type 2 diabetes in a Sub-Saharan African population.

Aim: Type 2 diabetes is increasing in Sub-Saharan Africa, but the pathophysiology in this population is poorly investigated. In Western populations, the incretin effect is reduced in type 2 diabetes, leading to lowered insulin secretion. The aim of this study was to investigate the incretin effect in a group of Sub-Saharan Africans with type 2 diabetes.

Hyperthermia is a severe complication to intake of methamphetamines due to generalised overactivation of metabolism and muscle activity combined with vasoconstriction. In this case report, a patient presented to the emergency department after injection of 2 g "crystal meth", and advanced into fatal hyperthermia and organ failure in the intensive care unit. Treatment of substance-induced hyperthermia is symptomatic and reducing metabolism with benzodiazepines and actively lowering body temperature with ice packs and cold intravenous fluids are appropriate interventions.

Effect of an Intensive Lifestyle Intervention on Glycemic Control in Patients With Type 2 Diabetes: A Randomized Clinical Trial.

Importance: It is unclear whether a lifestyle intervention can maintain glycemic control in patients with type 2 diabetes.

Objective: To test whether an intensive lifestyle intervention results in equivalent glycemic control compared with standard care and, secondarily, leads to a reduction in glucose-lowering medication in participants with type 2 diabetes.

Design, Setting, And Participants: Randomized, assessor-blinded, single-center study within Region Zealand and the Capital Region of Denmark (April 2015-August 2016).

Pyrexia's effect on the CBG-cortisol thermocouple, rather than CBG cleavage, elevates the acute free cortisol response to TNF-α in humans.

Corticosteroid-binding globulin (CBG) cleavage promotes local cortisol delivery in inflammation. Enzymatic cleavage of high-affinity CBG to low-affinity CBG (haCBG to laCBG) occurs at inflammatory sites and is now measurable in vivo; however, the time kinetics of haCBG depletion following an inflammatory stimulus is unknown. Hence our aim was to determine the immediate effect of the key pro-inflammatory cytokine TNF-α on CBG levels and cleavage.

The effect of alternate-day caloric restriction on the metabolic consequences of 8 days of bed rest in healthy lean men: a randomized trial.

Unlabelled: Physical activity and alternate-day fasting/caloric restriction may both ameliorate aspects of the metabolic syndrome, such as insulin resistance, visceral fat mass accumulation, and cognitive impairment by overlapping mechanisms. The purpose of this study was to test the hypothesis that alternate-day caloric restriction (ADCR) with overall energy balance would reduce insulin resistance and accumulation of visceral fat, in addition to improving cognitive functions, after 8 consecutive days in bed. Healthy, lean men (n = 20) were randomized to 1) 8 days of bed rest with three daily isoenergetic meals (control group, n = 10); and 2) 8 days of bed rest with 25% of total energy requirements every other day and 175% of total energy requirements every other day (ADCR group).

The effect of 8 days of strict bed rest on the incretin effect in healthy volunteers.

Bed rest and physical inactivity are the consequences of hospital admission for many patients. Physical inactivity induces changes in glucose metabolism, but its effect on the incretin effect, which is reduced in, e.g.

The incretin effect in critically ill patients: a case-control study.

Introduction: Patients admitted to the intensive care unit often develop hyperglycaemia, but the underlying mechanisms have not been fully described. The incretin effect is reduced in patients with type 2 diabetes. Type 2 diabetes and critical illness have phenotypical similarities, such as hyperglycaemia, insulin resistance and systemic inflammation.

Glucose metabolism in critically ill patients: are incretins an important player?

Critical illness afflicts millions of people worldwide and is associated with a high risk of organ failure and death or an adverse outcome with persistent physical or cognitive deficits. Spontaneous hyperglycemia is common in critically ill patients and is associated with an adverse outcome compared to normoglycemia. Insulin is used for treating hyperglycemia in the critically ill patients but may be complicated by hypoglycemia, which is difficult to detect in these patients and which may lead to serious neurological sequelae and death.

Tumour necrosis factor-alpha infusion produced insulin resistance but no change in the incretin effect in healthy volunteers.

Background: Type 2 diabetes mellitus (T2DM) is associated with peripheral insulin resistance, impaired incretin effect, and increased plasma levels of tumour necrosis factor-alpha (TNF-α). Although TNF-α infusion at a dose that induces systemic inflammation in healthy volunteers has been demonstrated to induce peripheral insulin resistance, the influence of this cytokine on the incretin effect is unknown.

Methods: We investigated whether systemic inflammation induced by TNF-α infusion in healthy volunteers alters the incretin hormone response to oral and intravenous glucose loads in a crossover study design with ten healthy male volunteers (mean age 24 years, mean body mass index 23.
