Filter by:The purpose of this study is to use 24 hour continuous glucose monitoring in older patients with diabetes who present with symptoms of falls, or dizziness, or confusion, that may indicate hypoglycaemia.
Surgery on the gastrointestinal (GI) tract results in profound changes to the metabolic profile. This is well described, including the rapid resolution of diabetes seen after bariatric surgery. The underlying pathophysiology, and incidence in lean patients undergoing surgery for cancer, is somewhat less described. The investigators plan to assess the symptomatic and glycaemic profile, as well as causative pathways, for metabolic symptoms in patients after surgery on the GI tract. The investigators will use glucose tolerance tests, physiological challenges with somatostatin analogues and antibiotics, and assess tissue transcriptomic changes.
Patients with insulin-dependent diabetes mellitus (DM) and chronic kidney disease (CKD) exhibit an excessive risk for cardiac arrhythmias, in particular sudden cardiac death (SCD). Various studies have shown that hypoglycemic episodes are strong predictors of cardiovascular mortality in both type 1 and type 2 diabetic patients. Experimental data and small clinical studies link hypoglycemia with ECG changes and SCD, but little is known about the direct association of hypoglycemic events and/or rapid swings in blood glucose with arrhythmias in this high risk population. Ideally, an algorithm should help to identify patients at risk for hypoglycemia-associated arrhythmias and SCD, but hitherto systematic analyses of blood glucose values and 12-channel ECGs are lacking in these patients. In this validation study a 12-lead ECG T-shirt consisting of textile electrodes and a data logging device wich can record long-term 12-lead ECG data will be tested. The purpose of the T-shirt is to improve the patient's comfort for long-term recordings and to prevent adverse effects of regular ECG electrodes. Current systems are limited by the use of ECG electrodes involving disadvantages like severe direct side effects on the skin such as rash and bullous lesions as well as slipping electrodes. By the means of the proposed ECG T-shirt those drawbacks will be avoided.
It is known that hypoglycaemia affects various domains of cognitive function. One aspect of cognitive function is 'social cognition', which is our ability to interpret facial expressions, gestures and speech. It is an approach to understanding human judgement and behaviour. There is anecdotal evidence for negative behavioural responses such as aggressiveness and argumentativeness during hypoglycaemia and while research has shown that hypoglycaemia can cause significant changes in mood, little information exists regarding its effect on social cognition. It is therefore not known whether hypoglycaemia affects this aspect of cognitive function but, if it did, it could explain why people with low blood sugar due to insulin treatment are often resistant to offers of help (for example, they may misinterpret a friendly gesture as being threatening). Knowledge of this effect of hypoglycaemia can be used to educate relatives and carers of people with diabetes who may suffer this problem. Hypoglycaemia is also known to have an effect on the electrical rhythm of the heart. This is thought to be secondary to adrenaline secretion during hypoglycaemia which provokes a fall in the blood level of potassium, a type of electrolyte. Other electrolyte imbalances are known to predispose to heart rhythm abnormalities or arrhythmias in other situations and it is not known if the levels of these other electrolytes are affected during hypoglycaemia. Using specific tests of social cognition and continuous electrocardiographic (ECG) monitoring, this study aims to find out whether social cognition is affected by an hour of hypoglycaemia and how hypoglycaemia affects blood electrolyte levels and the electrophysiology of the heart.
Low blood sugar levels are common in babies after birth. This may be normal as babies can use other sources of energy. However if a baby does not produce these fuels the brain can be starved of energy and be damaged. Measurement of these fuels is not done as part of clinical practice in the newborn. The investigators aim to see whether at the same time as taking the blood sugar level from a heel prick these fuels can be measured in a small drop of blood. At the same time as blood needs to be taken for clinical reasons the study team will to take a drop of blood from 50 babies to see how good the point of care (POC) meters are compared to the laboratory at measuring these fuels. If accurate these POC meters could identifying those at risk from brain damage as well as prevent separation of mothers and babies who are establishing breast feeding.
Development of a training concept for health care professionals (nursing and medical staff), according to the current guidelines on treatment of in-patients with Diabetes. Primary endpoint is the change in hypoglycaemia rates comparing data before and after the training. Hereby we can derive the effects of staff training on the quality of health care in this patient population.
The purpose of this study is to evaluate the impact of a software for smartphones and tablets on type 1 diabetes control and quality of life
Backgrounds/Aims: It was the aim to prospectively study the optimum regime of "preventive" carbohydrate administration for prevention of hypoglycaemic episodes during a standardized bout of physical activity.
A small, pilot, randomised, cross over trial that investigates the potential for DPPIVi therapy to reduce insulin requirements in type 1 diabetes was studied. We investigated whether this drug reduces daily insulin doses, leads to weight reduction, reduces blood glucose fluctuation and improves glucose control. Through reduction of blood glucose variability, we want investigated, whether it has the capability of improving the magnitude of epinephrine responses at 2.5mmol/L by performing a hyperinsulinaemic, hypoglycaemia clamp study after each arm. A successful outcome would then lead to an application for funds for a larger, multicentre intervention study. The benefits of this therapeutic advance are clear and this has the potential to make a dramatic improvement to the lives of people with type 1 diabetes in our community.
The purpose of this study is to evaluate the accuracy and reliability of the continuous glucose monitoring system the FreeStyle Navigator® (Abbott, Diabetes Care) in critically ill patients by comparing subcutaneous measuring with the current standard of arterial measuring by a point of care glucometer.
