Mechanisms Underlying Postoperative Insulin Resistance and Inflammation

Obesity

Having an operation places an enormous burden on the body, leading to the development of inflammation and so called 'insulin resistance'. Insulin resistance means the body is unable to respond to important hormones that control use of energy. Recent studies have shown that patients who develop 'higher' insulin resistance and inflammation have more serious complications and take longer to recover after surgery. The investigators do not know what controls the development of insulin resistance and inflammation after surgery. Similarly, the investigators do not know why certain patients develop much more insulin resistance and inflammation than others, even though they have the same operation. The main purpose of the study is to try to find out which patients are prone to developing greater 'amounts' of insulin resistance and inflammation. The investigators also want to find out whether the investigators can reduce the 'amount' of insulin resistance and inflammation in these patients (for example by giving them carbohydrate [sugar-based] drinks before surgery - these have been shown to reduce insulin resistance in some patient groups). Information from this study should improve the way the investigators prepare patients before surgery and this should help to improve patient outcomes following surgery (by reducing complications and speeding recovery after major surgery).

Mechanisms of Atherogenesis During Post-prandial Time in Childhood Obesity

Childhood ObesityEndothelial Dysfunction2 more

Childhood obesity is increasing at a fast pace, together with its complications. The aim of the present study is to assess several candidate triggering agents, mechanisms and intermediate phenotypes of atherosclerosis during the post-prandial phase in the obese insulin-resistant child/adolescent.

Synbiotics and Low Grade Inflammation in Obese Subjects

ObesityDiabetes Mellitus Type-22 more

The purpose of this study is to determine whether the daily administration of a synbiotic (oligofructose and Bifidobacterium animalis subsp. lactis Bb12) for six weeks contributes to improve the glucose tolerance and the low grade inflammation (as reflected as the plasmatic concentrations of ultrasensitive CRP, IL-6, sCD14 and LPS-binding protein) in obese subjects.

Sleep Apnea Syndrome on Acromegaly: Impact of the Treatment on the Carbohydrates Metabolism.

AcromegalyObstructive Sleep Apnea1 more

Sleep apnea is a common situation that affects up to 80% of acromegalic patients. This disease is linked to disturbance on the carbohydrate metabolism increasing the rates of diabetes. The objective of this trial is to assess (with the euglycemic hyperinsulinemic clamp) the impact of the treatment of sleep apnea, with a continuous positive air pressure device (CPAP), on the insulin resistance.

An Exercise Intervention Study in Insulin-Resistant Adolescents

Insulin ResistanceObesity

Hypothesis: Insulin-resistant African-American and Hispanic adolescents will show significant improvement of insulin sensitivity (SI) and positive changes associated with fibrinolytic markers and lipid profile after a two month supervised aerobic training.

Study to Examine Insulin Resistance During Growth Hormone Treatment for Short Stature Due to Low...

Fetal Growth Retardation

Insulin resistance is common among children with low birthweight. Moreover, growth hormone treatment for ensuing short stature also causes insulin resistance. Our objective is to examine these processes. Insulin resistance has recently been linked to the accumulation of stores of fat in muscle cells which can be measured by MRI. We hypothesize that children who are short due to low birthweight have increased muscle fat stores, but that growth hormone treatment will paradoxically reverse this association. To test this hypothesis, muscle fat stores will be measured in children who are short due to low birthweight before and after receiving growth hormone therapy. Other parameters linked to insulin resistance (glucose tolerance, blood markers, and body composition) will also be assessed. This study may lead to ways to increase growth hormone safety and dose limitations.

Is There Association Between Vitamin D Levels And Insulin Resistance In Polycystic Ovary Syndrome?...

Polycystic Ovary SyndromeInsulin Resistance1 more

The primary aim of the current study is to clarify whether serum vitamin D levels [25(OH)D3] have a temporal association with insulin resistance and/or insulin sensitivity in PCOS women versus healthy ones. To achieve this aim, the investigators will conduct a prospective observational study involving obese and lean PCOS women in comparison to obese and lean healthy subjects living in Cairo, Egypt.
