Filter by:This project aims to a) evaluate the effects of selected antipsychotic medications on insulin action in skeletal muscle (glucose disposal), liver (glucose production) and adipose tissue (whole-body lipolysis), b) evaluate the effects of selected antipsychotic medications on abdominal adipose tissue mass, total body fat and total fat-free mass, and c) explore the longitudinal effects of treatment with selected antipsychotics on glucose tolerance, lipid profiles, abdominal adipose tissue mass, total body fat and total fat-free mass. These hypotheses will be evaluated by measuring 1) whole-body glucose and lipid kinetics with the use of "gold-standard" stable isotope tracer methodology, 2) body composition using dual energy x-ray absorptiometry and magnetic resonance imaging, and 3) longitudinal changes in glucose tolerance and lipid profiles. The aims will be addressed in non-diabetic schizophrenia patients chronically treated with risperidone, olanzapine, clozapine, quetiapine, ziprasidone, or haloperidol, and untreated healthy controls. Re-evaluations will also be performed in patients who are randomized to switch from their current antipsychotic (from the above groups) to risperidone, olanzapine, quetiapine, or ziprasidone for 6 months. Relevant data is critically needed to target basic research, identify long-term cardiovascular consequences, and plan therapeutic interventions.
This is a single-center, open, non-controlled clinical investigation in 10 patients at the Medical University Graz including a treatment visit (V1)and a follow up visit(V2). In the treatment visit (V1) after admittance to the ICU arterial blood glucose values will be monitored and either the software-algorithm eMPC will be used to adjust the infusion rate of intravenously administered human soluble insulin to normalise arterial blood glucose. The purpose of the present study is to investigate the performance of the already developed and tested algorithm in combination with a newly developed bed-side, touch screen user interface (CS-1 decision support system) in patients at the medical ICU for a period of 72 hours. Follow up information(V2) will be acquired at hospital discharge or at the latest one week after visit 1.
BACKGROUND AND PURPOSE Critical illness hyperglycemia (CIH) - elevated blood glucose in the critically ill patient population - has gained much interest among health care providers over the past several years. Clinical studies in adults have documented a high rate of hyperglycemia in some post-surgical and medical intensive care units (ICUs). However, the primary reasons for interest in this topic are not due just to its high rate, but also to the fact that by returning the high glucose levels found in this population to normal with insulin therapy can dramatically improve clinical outcomes by decreasing both morbidity and long-term mortality. Because of this, aggressive glucose control has become common practice in adult ICU critical care management. Although there is substantial data describing the high incidence of CIH in adult patients, there is little information regarding this condition in children. A single retrospective study recently published also suggested a high incidence of CIH in children with critical illness secondary to both medical and surgical causes. It is yet to be determined if, like in adults, normalizing blood glucose levels with insulin improves outcomes in this pediatric population. Because evidence appears compelling that hyperglycemia is both common and detrimental in adults, many pediatric ICUs have likewise begun to focus on aggressively treating hyperglycemia in critically ill children. The proposed study is a prospective observational pilot study to occur in the Pediatric Intensive Care Unit (PICU) at Children's Healthcare of Atlanta at Egleston. This prospective pilot study is being done to evaluate the endocrine factors associated with, if not responsible for, CIH, and the changes that take place with the restoration of normal blood glucose levels by insulin therapy. To address these profound issues this study will pursue two interrelated Aims: Aim #1: To determine if critical illness hyperglycemia is associated with absolute insulin deficiency, peripheral insulin resistance, or both. Aim #2: To characterize the requirement of insulin required to initially restore and maintain normal blood glucose levels, and compare the changes in insulin that take place with this normalization in patients with CIH. We hypothesize that the hyperglycemic response to critical illness will be associated with abnormally low levels of insulin as compared to patients without critical illness hyperglycemia.
The objective of this project is to understand defects in insulin secretion that contribute to abnormal glucose metabolism in patients with diabetes. In particular the effects of signals released from the intestine to stimulate insulin secretion will be tested. Patients with type 2 diabetes will have insulin secretion in response to glucose and intestinal factors before and after insulin treatment to lower their blood glucose. It is expected that the results of this work will provide valuable information for treating diabetic people.
Surgery performed during general anesthesia induces a stress effect on the body. Our plan is to identify population at risk of hyperglycemia during perioperative period.
This is an open mono-centre randomised controlled trial performed at the Medical University Graz including a treatment visit (V1). In the treatment visit (V1) after admittance to the ICU arterial blood glucose values will be monitored and either the software-algorithm eMPC will be used to adjust the infusion rate of intravenously administered human soluble insulin to normalise arterial blood glucose or routine treatment will be used to establish tight glycaemic control. The treatment visit will last for 72 hours. The primary hypothesis of the study is that blood glucose control by the eMPC algorithm is not inferior compared to the implemented routine protocol.
Hyperglycemia is frequent manifestations of the human metabolic response to systemic inflammatory response syndrome (SIRS),sepsis and septic shock, and are implicated in the clinical outcome. Adrenomedullin is elevated in SIRS, sepsis and septic shock and has been demonstrated the inhibitory role on insulin and adrenocorticotropic hormone secretion. Our hypothesis is that: AM elevation after SIRS could be the responsible to maintain hyperglycemia
To determine if the omentectomy diminishes hyperglycemia and improves the resistance to the insulin in patients with morbid obesity and propensity to develop to Diabetes Mellitus type 2.
The results from the DECODE Study have shown that postprandial (1 - 2 hours after a meal) hyperglycemia (elevated blood sugar) is more common in elderly people with diabetes than younger people with diabetes and is the best predictor of the development of complications. The DECODE Study involved 6941 people who already had diabetes and 702 who did not have diabetes. Diabetes is diagnosed when the blood sugar 1st thing in the morning is over 7.0 mmol/L. The DECODE Study showed that people at risk for diabetes can have a normal blood sugar 1st thing in the morning but have a high blood sugar 2 hours after a meal and that these people are at risk for developing heart disease and other complications of diabetes. These people would not be identified as at risk if only a fasting blood sugar is done. Studies in younger people with diabetes have shown that after a meal, insulin levels are more like a person without diabetes and glucose (blood sugar) levels are lower with GlucoNorm than with Glyburide. There is no data available that demonstrates this in elderly people with type 2 diabetes. You have been invited to participate in this study because you have type 2 diabetes controlled by diet and/or exercise or metformin only and are over 65 years of age. The purpose of this study is to determine whether GlucoNorm has a greater effect than Glyburide on insulin levels and glucose (blood sugar) levels after a meal in elderly people with type 2 diabetes who control their diabetes with diet and exercise.
Critically ill children, including children undergoing heart surgery, commonly develop elevated blood glucose (also known as "blood sugar") levels during their illness, which can lead to poor health outcomes and an increased risk of death. This study will examine the effectiveness of maintaining normal blood glucose levels at decreasing infections and improving recovery in young children undergoing heart surgery.
