View clinical trials related to Hypoglycemia.
Filter by:Hypoglycemia (HG) is common and can be dangerous in diabetes mellitus, so identifying patients at risk may lead to useful preventive strategies and improved quality of care and health outcomes. This study will test the implementation of a computerized alert tool for clinicians.
This study evaluates the difference in post prandial tissue glucose levels between two variation of Roux-en-Y Gastric bypass by continuous glucose monitoring.
Prior to caesarean section, patients should fast from solid food for 6 hours and from clear fluids for 2 hours. Carbohydrate drinks can also be consumed up to 2 hours before surgery. These drinks have been shown to improve patient well-being after surgery and may potentially improve the neonatal blood glucose level after delivery and reduce the risk of a low blood glucose level. This study aims to assess the influence of pre-operative carbohydrate drinks on blood glucose levels of the baby at delivery.
Advanced glucose monitoring systems have revolutionized diabetes care and enabled people with diabetes to achieve better diabetes control with reduced risk of hypoglycaemia. Continuous glucose monitoring (CGM) systems provide real-time glucose monitoring and alarms when glucose approaches extreme readings (hypoglycaemia and hyperglycaemia) or when the change in glucose is rapid. All available CGM systems, except Dexcom G6, require daily calibrations with capillary glucose readings in order to attain accuracy of glucose readings. Decom G6 system is not widely accessible and only available in certain countries. Flash glucose monitoring systems (Flash) provide glucose readings when users actively scan their sensors. FreeStyle Libre (FSL) is the only Flash glucose monitoring system currently available in market. FSL is factory calibrated and sensors are ready to use after placement and initiation. The two main differences between Flash and CGM are user interaction and the alarm facility. While CGM provide real-time glucose readings, Flash is user-dependent for actively scanning and understanding the readings. Moreover, CGM systems provide alarms for low or high glucose and for rapid glucose changes, while Flash does not routinely provide alarms. This is particularly relevant when patients have impaired or lost hypoglycaemia awareness. CGM systems are costlier compared to Flash, which has contributed to the wider adoption of FSL. Several Bluetooth adjuncts have been introduced to market for FSL. These devices attach to Libre sensor and connect to the user's mobile phone via Bluetooth. This enables continuous and real-time feed of glucose readings from the sensor to patient's mobile phone, which enables a wide range of customizable alarms for high and low glucose levels and for rapid glucose changes. This setup also enables calibration of Libre sensor with capillary glucose which, anecdotally, has been reported to improve sensor accuracy. None of these adjuncts have been validated clinically. FSL with Bluetooth adjunct such as MiaoMiao remain cheaper than current CGM options and could be more accessible in some countries than CGM. However, without robust evidence to support effectiveness and safety of such setup it is not possible to recommend this. The Objective of this study is to determine whether FSL with Bluetooth Adjunct is superior to FSL alone in accuracy and reduction of hypoglycaemia burden.
Observational, within-subject, crossover study To assess the impact of Dexcom G6 RT-CGM with a predictive hypoglycaemia alert function on the frequency, duration and severity of hypoglycaemia occurring before, during and after regular physical activity in people with type 1 diabetes At Imperial College Healthcare NHS Trust have established the multi-disciplinary Imperial Physical Activity and Diabetes (IPAD) clinic to empower, educate and enable people with diabetes to manage their blood glucose when they undertake physical activity. The investigator utilise the skills and expertise of a consultant diabetologist, a diabetes dietitian, a consultant in sports & exercise medicine, and a diabetes specialist nurse with expertise in diabetes technology. The investigator have access to diagnostic & therapeutic radiology, physiotherapy and psychology services.
In the effort of better understanding the glucose control in people with type 1 diabetes, in-depth insight into the physiology of hepatic glucose production and its influencing factors is essential. Previously, a number of potential influencing factors of hepatic glucose production have been investigated, including insulin-on-board, low carbohydrate diet, preceding ethanol intake, exercise and multiple stimulations of hepatic glucose production. Previous post-hoc analysis of dual-hormone closed-loop systems has indicated that the rate of fall in blood glucose influences the following stimulation of hepatic glucose response. However, the rate of fall in blood glucose is highly related to insulin levels, which may explain those findings. Thus, in this study the investigators want to examine whether the different rates of fall in blood glucose with similar insulin levels on board affect the hepatic glucose response in individuals with type 1 diabetes. In the study, which will be conducted at Steno Diabetes Center Copenhagen, participants will complete two study visits. On each visit, a hypoglycemic clamp technique will be used to lower the blood glucose levels of the participants (using either a rapid or slow decline rate), whereupon hepatic glucose production will be stimulated using low-dose glucagon. The study days are divided into four phases: 1) preparation phase, 2) hyperinsulinemic euglycemic phase (stabilization of blood glucose), 3) hyperinsulinemic hypoglycemic phase (rapid or slow decline in blood glucose) and 4) post-glucagon administration phase. This design will allow the investigators to examine whether differences in hepatic glucose response exist depending on preceding rate of fall in blood glucose. We hypothesize that the rate of fall in blood glucose does not affect the hepatic glucose production.
According to the Standards of Medical Care in Diabetes by the American Diabetes Association, people with diabetes should aim for 30 minutes of moderate-to-vigorous intensity aerobic exercise at least 5 days a week or a total of 150 minutes per week and doing some type of strength training at least 2 times per week in addition to aerobic activity. However, the effects of different forms and intervals of exercise on glycemic control are not well established. Exercise increases the risk of hypoglycemia both during and several hours after exercise. There are several strategies to avoid hypoglycemia during exercise. The most common strategy is to reduce insulin and to take carbohydrates before the exercise starts. Short-acting insulin analogs have a duration of approximately four hours, thus reductions need to be planned and done well in advance before the exercise starts. Since different types of exercise (aerobic, strength training or high intensity training) affect blood glucose in different ways and most exercise sessions include a combination of the types, these strategies are often associated with difficulties in obtaining stable blood glucose. The American Diabetes Association guidelines do not explicitly recommend a daily workout routine but outline recommendations for weekly amounts of exercise as there is currently insufficient evidence on the ideal timing, frequency and duration of exercise for preventing hypoglycemia. Hypothesis: in people with type 1 diabetes, time in hypoglycemia can be reduced if exercise is performed daily over five consecutive days compared to the same total amount of exercise performed at 2 days with at least 2 days interval. Aim: to evaluate the impact of the same total amount of exercise split into either five consecutive sessions or two sessions with at least 2 days in between on percentage of time spent in hypoglycemia and other glycemic parameters in people with type 1 diabetes.
Evaluate if the implementation of a hypoglycemia protocol with glucose gel has reduced the NICU admission rate of neonates with low-acuity neonatal hypoglycemia.
This study involves two parts: a randomised controlled trial, and a nested qualitative study. The main aim of the trial is to evaluate the effectiveness of a pharmacist-led, medications-focused patient counselling on reducing the frequency of hypoglycaemia in older adults diagnosed with type 2 Diabetes Mellitus within 12 weeks in Jordan. The study hypothesis is that individualised patient counselling which is provided by pharmacists and involves recommendations about anti-diabetic medications will reduce the risk of hypoglycaemia by preventing further episodes in the elderly Jordanians with type 2 Diabetes Mellitus. The qualitative study aims at evaluating the experience of participants in both groups with the study (process evaluation). This involves exploring which components are effective and which are not with the reasons, the contextual factors affecting the delivery and implementation of the study and the intervention, and how the study and the intervention can be scaled up in the future.
The overall objective of this study is to investigate whether hypoglycaemia (the most potent stimulus of pancreatic glucagon secretion) affects the secretion of gut-derived glucagon in totally pancreatectomized patients.
