Active clinical trials for "Hyperglycemia"

The technique of blood samples extraction from the radial artery through an arterial catheter with a 3-way stopcock and automated washing with valve of fast flow is better than the one carried out through a fixed reusable arterial blood sample syringe and its manual washing because it shows a minor incidence of the complications originated from technical manipulation as infection, pseudo-aneurysm, ischemia or thrombosis of radial artery or obstruction of the catheter. The purpose of this study is to evaluate the efficacy, in terms of adverse effects, of blood samples obtention using an arterial catheter with needless connector closed system or an arterial catheter with an arterial blood sample syringe. Also a second purpose is to compare once a day (at the same time) the values of glycose blood levels between bedside glucometer determination of arterial catheter extraction and capillar puncture, and lab determination of glycose from venous puncture, in order to determinate fluctuation in glycose levels due to peripherical hypoperfusion or to vasoactive drugs received by these in-intensive care unit patients.

This is a pilot acute dietary intervention study with a randomized cross-over design aiming to investigate whether acute supplementation of extra virgin olive oil (EVOO) rich in oleocanthal could attenuate postprandial hyperglycemia and activation of platelets in T2DM patients. For this reason, non-insulin dependent diabetic patients (10-15) will be randomly assigned to consume in five different days white bread (50 g CHO) with butter, butter with ibuprofen, refined olive oil and olive oil with oleocanthal (250 mg/Kg 500 mg/Kg). Blood samples will be collected pre- and post-intervention up to 4 hours in order to determine platelet aggregation, postprnadial glycemia, lipemia, inflammation and oxidative stress. Taking into account the strong anti-inflammatory and anti-platelet properties of oleocanthal, this study will assess whether oleocanthal-rich olive oils could exert similar effects under real in vivo conditions in T2DM patients. It will also assess whether these effects are achieved through improvement of postprandial glycemia and lipemia.

Dexamethasone is a steroid commonly used for the prevention of chemotherapy-induced nausea and vomiting (CINV). While effective, high dose dexamethasone is associated with numerous side effects, even when used for a short duration. One such effect is elevated blood glucose, or hyperglycemia. Current literature suggests increased risk of infection, poor wound healing, and increased mortality in non-cancer surgical patients with steroid-induced hyperglycemia. There is also evidence to support that elevations in blood glucose are associated with worsened outcomes in cancer patients. Much of this data comes from cancer patients that are treated in an inpatient setting where blood glucose is routinely checked. Limited data is available describing the fluctuations in blood glucose following dexamethasone administration in cancer patients being managed in an outpatient setting, such as the Anschutz Cancer Pavilion (ACP) Infusion Clinic. This study aims to characterize the effects dexamethasone has on blood glucose in cancer patients by utilizing Continuous Glucose Monitoring (CGM) devices. These devices are minimally invasive, are FDA approved, and can produce real-time data of blood glucose fluctuations over a course of 3-7 days. By inserting the devices under the skin of the abdomen, the investigators can evaluate the temporal relationship between glucose abnormalities and dexamethasone administration. Results from this study will not only increase the knowledge base of dexamethasone-induced hyperglycemia and identify patients at increased risk, but also allow future research to be conducted in order to determine if standard protocols can proactively minimize steroid-induced glucose fluctuations.

This pilot study aims to evaluate the feasibility of close glucose monitoring and management of patients (targeting fasting and pre-meal glucose of 4-7 mmol/L) using state-of-the-art flash glucose monitoring (FGM) technology. The glycemic intervention will be personalized based on individual blood glucose levels. Although the glycemic interventions used in this study include standard medications and methods of glucose monitoring used for patients with diabetes, this pilot study will specifically evaluate the feasibility of using these approaches in patients with GBM, appreciating their additional medical, functional and social challenges.

Normoglycemia is important for the outcome of surgical and medical conditions. Insulin infusions have been studied to achieve normoglycemia during these circumstances and have proved to be useful. Insulin given by subcutaneous injections has longer duration compared to intravenous given insulin which makes it more difficult to control. The hypothesis behind the trial is the concept that insulin infusion is more effective in reaching normoglycemia in diabetic subjects during foot ulcer infection and surgical wound infection. The study evaluates a target controlled insulin infusion or conventional therapy as antidiabetic treatment during foot ulcer infection and surgical wound infection. Secondary efficacy parameter will be hospital stay, laboratories for inflammation and oxidative stress.

Stress hyperglycaemia is a well-known risk factor of postoperative morbidity and mortality in cardiac surgery. Recently, several authors have reported that increased blood glucose (BG) variability could worsen the prognosis in this population.The transcatheter aortic valve implantation (TAVI) is a low invasive procedure proposed as an alternative technique to aortic valve replacement surgery in high-risk patients. The aim of this study is to describe the incidence of stress hyperglycaemia and assess whether BG variability could impact the outcome of patients undergoing TAVI.

Severe intraoperative hyperglycemia (SIH) is recognized as one of the important risk factors for the increasing of the postoperative infections rate, which can negatively affect the final outcome of surgical treatment. Studies in recent years have shown a much higher incidence of wound infections, respiratory and urinary tract infections in patients who intraoperatively had an increase in blood glucose level (BGL) above 180 mg/dl (10 mmol/l). This problem in neurosurgery is especially important due to the high proportion of patients with acute injuries and potentially long-term need for postoperative intensive care, as well as the frequent use of drugs that increase blood glucose level (steroids) in neurooncology. Most published studies include patients from both of these groups. This study is aimed to assess the impact of severe intraoperative hyperglycemia on the incidence of infectious complications only in patients scheduled for elective intracranial interventions.

Critically ill children have abnormal utilization of nutrients such as glucose, lipids and protein. Often sick children have increased glucose concentrations in blood. However, the origin of the high glucose has not been determined in these populations. There is a close interrelationship between protein and energy metabolism. An increase in the energy supply will not promote nitrogen retention unless the amino acid supply is adequate, and conversely, an increased amino acid supply will be useless if energy is limiting, hence the importance of adequate protein and energy intake. Our study aims to investigate the protein-energy interactions in critically ill septic children and adolescents with the objective to eventually provide the best nutritional support for these patients.

Glycemic variability in critically ill patients is a recognized negative prognostic factor. The molecular mechanisms determining inter-patients variability in glucose metabolism during stress are not fully understood. The Phosphatase and Tensin homolog (PTEN) is known to influence glucose homeostasis by interfering in intracellular insulin signaling. Aim of this study is to ascertain whether differential expression of PTEN in critically ill patients correlates with glycemic variability and clinical outcome.

Determine if routine BG testing at the time of ICU admission is being done on all patients, irrespective of a prior diagnosis of diabetes mellitus, and whether it provides clinically important information.
