Filter by:Surgery induces a stress effect on the body partially through a catabolic energy state. In turn, glucose levels may rise to levels which have been associated with major morbidity (Golden, 1999) and mortality (Ouattara, 2005). An increasing body of evidence suggests that intensive insulin therapy for tight control of blood glucose levels in certain surgical and critical care patient populations may improve mortality and selected morbidity outcomes when compared to those patients receiving conventional insulin therapy and blood glucose management. More specifically, poor intra-operative blood glucose control is associated with worse outcome after cardiac surgery. Intensive insulin therapy with tight blood glucose control in surgical patients while in the ICU may reduce morbidity and mortality. Such outcome improvements would clearly provide benefits to patients, providers and payers. To date, there is scant research examining whether intensive insulin therapy for tight control of blood glucose in the perioperative period can alter outcomes for the non cardiac surgery population. The purpose of this study is to determine whether intensive insulin therapy for tight control of blood glucose in the perioperative period in non cardiac major surgery patients is associated with altered morbidity and mortality rates.
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.
The purpose of this study is to determine the effect of preventing hyperglycaemia in patients admitted to hospital with acute exacerbations of chronic pulmonary disease.
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.
Glucose control has been shown as an important and independent prognostic factor in several acute conditions in hospitalized patients, including Acute MI, stroke, cardiac surgery and in critical care units. Patients with acute exacerbation of COPD (AECOPD)and diabetes treated with insulin had a longer in-patient stay and more frequent isolation of Gram negative bacteria from sputum than those without diabetes.Hyperglycemia (>11 mmol/l) on admission predicted failure of non-invasive ventilation and infectious pulmonary complications in patients admitted to the ICU with acute respiratory failure caused by severe AECOPD. The primary goal of this study is to test the hypothesis that in AECOPD, tight glycemic control during hospital stay will improve outcome of hospitalization. The secondary goal of this study is to test new ways in controlling patients in the internal medicine ward.
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.
