Filter by:Iatrogenic hypoglycemia is still considered to be the number one barrier to effective glycemic control in patients with type 1 diabetes (T1D). In a previous study, we observed in dogs that liver glycogen content can be a determinant of hormonal and hepatic responses to insulin-induced hypoglycemia. In the experiments described herein, we will determine if nutritionally-manipulated changes in liver glycogen concentrations have an impact on hypoglycemic counterregulation in non-T1D control subjects.
This study will explore the cerebral mechanisms of impaired awareness of hypoglycemia (IAH) in type 1 diabetics following exposure to experimental recurrent hypoglycemia (HG). To induce IAH, patients with T1D identified to have normal awareness of hypoglycemia (NAH) will undergo three 2-hour long hypoglycemic clamps. Neurochemical profiles will be measured by high field MRS before and after induction of IAH. Subject glycemic variability and activity/sleep for 1 week before each study will be monitored as all factors have been shown to alter responses to HG.
Hypoglycemia (low blood glucose) is a very common problem in newborns, and has been associated with poor neurodevelopment, cognition, and school performance. At-risk newborns (infants of diabetic mothers [IDM], large [LGA] and small [SGA] for gestational age infants, and late preterm [LPT] infants) undergo a hypoglycemia screening protocol that involves numerous intermittent needle sticks to test glucose levels on bedside glucometers; however, continuous glucose monitoring (CGM, currently not approved for clinical use in babies), via a small sensor placed in the thigh (only 1 needle stick), would likely decrease pain while providing continuous glucose levels. This study will evaluate the feasibility, safety, and precision of CGM in at-risk newborns, and determine if this method would decrease the amount of painful procedures and episodes of hypoglycemia missed by intermittent sampling. As part of regular medical care, participants will undergo intermittent blood glucose screening with heel sticks as per the current hospital standard of care protocol. Regular medical care involves checking the participant's blood glucose via heel stick every few hours using a bedside glucometer, with another heel stick to confirm low values in the laboratory. If the participant has low values, he/she may be treated with oral glucose gel, feedings of breast milk or formula, or intravenous (IV) fluids in the Neonatal Intensive Care Unit (NICU). This research study involves placing a CGM device in addition to undergoing the current blood glucose screening protocol and treatment. As soon as possible after birth, a continuous glucose monitoring device (Dexcom G7) will be placed on the participant's thigh by a research team member, and will blindly continuously record glucose levels that will be analyzed after discharge. Everyone who agrees to participate in this study will have placement of this experimental device. The investigational device will stay in place for the same amount of time that a participant is undergoing blood glucose monitoring as per the current standard of care protocol, for a maximum of 7 days. A participant may need to have his/her blood glucose checked after 7 days for regular medical care (and not for research), because his/her glucose concentrations are still low. Being in the research study will not affect a participant's medical care, and will not affect how long he/she needs blood glucose monitoring or treatment. A research team member will place and remove the CGM. Nurses will evaluate the site of the device for signs of irritation, infection, bleeding, and any other issues at least 3 times per day. After discharge from the hospital, data will be collected from the participant's medical record and participant's mother's medical record, including the participant's sex and birth weight, blood glucose values, details of feedings, treatments given for low glucose concentrations, and NICU admission data. Data that will be collected from the participant's mother's medical record includes age and race, prenatal data, medical history, and medication use. The participant's parents will be asked to fill out a short survey about their experience with this device when it is removed.
The GEHPPI study is a multicentre placebo controlled randomized controlled trial that aims to prevent early hypoglycaemia in preterm newborns born at ≤32 week's gestation. To do this we will prophylactically administer to these newborns either a small amount of dextrose 40% gel early as possible after birth via the buccal route in the delivery room or a placebo. We hope this dextrose gel will prevent hypoglycemia occurring during the time period needed for the newborns to be transported to the neonatal unit where they will have their venous access inserted. This trial aims to demonstrate that administering dextrose gel via the buccal route is a simple and rapid method of preventing early hypoglycaemia in this vulnerable patient group. This trial aims to show that giving dextrose gel via the buccal route is simple and feasible in this premature population. This trial aims to reduce the need for rescue intravenous dextrose (2ml/kg dextrose 10%) in those babies who are hypoglycaemic at the time of obtaining intravenous access.
Neonatal hypoglicaemia is associated with impaired neurodevelopment outcomes in preterm infants. Thus, hypoglicemic events should be diagnosed and treated promptly. Unfortunately, hypo- and hyperglicaemia management is still controversial. The investigators aim to assess if a continuous glucose monitor (CGM) impacts on both short-term and long-term neurodevelopment. Primary outcome is the effect of CGM coupled with a control algorithm for glucose infusion on the number of hemodynamic significant events (defined as hypoglycemic events associated with DOT-detectable reduction of brain oxygenation). It will be enrolled newborns ≤32 weeks gestational age and/or of birthweight ≤1500 g, they will be randomized in two study arms, both of them will wear Medtronic CGM during the first 5 days of life: 1) Blinded group (B): the device monitor will be switched off, glucose infusion rate will be modified according to the daily capillary glucose tests. 2) Unblinded group (UB): the device monitor will be visibile, alarms for hypos/hyper will be active and glucose infusion rate will be modulated according to CGM and PID control algorithm. Enrolled newborns will also be monitored with near-infrared diffuse optical tomography (DOT) during the first 5 days from enrollment. Follow-up will be performed at 12, 18, 24 months and 5 years by neurodevleopmental scale (Bailey III until 24 months; Wechsler Preschool and Primary Scale of Intelligence (WPPSI) at 5 years). The estimated numerosity is 60 patients (30 for each arm).
The primary objective of this study is to assess the neuro-endocrine response to hypoglycaemia in PHH vs. non-PHH post-gastric bypass individuals.
The primary objective of this study is to observe the kinetics of pre-stored and de-novo synthesized insulin that is secreted into the circulation using an in-vivo heavy water (D2O) labelling experiment in patients with postprandial hyperinsulinaemic hypoglycaemia (PHH) and non-surgical non-PHH controls.
The primary objective of this study is to assess the effect of the natural course of postprandial hypoglycemia vs. a postprandial euglycaemic condition on driving performance in individuals with confirmed postprandial hyperinsulinaemic hypoglycaemia after gastric-bypass surgery.
Reducing hypoglycemia is an important aspect of management of type 1 diabetes (T1D) in older adults, many of whom have hypoglycemic unawareness, cognitive impairment, or both. Continuous Glucose Monitoring (CGM) offers the opportunity to reduce hypoglycemia and its related complications such as fractures from falls and hospitalizations and improve QOL including reducing hypoglycemic fear and diabetes distress. The potential benefit of CGM in reducing hypoglycemia in the older adult population has not been well studied. Prior and on-going trials compare CGM to self-monitoring of blood glucose levels, but none look at remote daily monitoring of CGM data or provision of telemedicine based on clinic notification of hypoglycemic events. This study is a 14 week, single center, pilot study of 10 subjects 65-75 yrs old with type 1 diabetes. The primary aim is to determine the effect of continuous remote CGM reporting coupled with a telemedicine intervention (Tele-CGM program) on rates of hypoglycemia in adults with T1D >65 years old. Study staff will review Tidepool uploads and call/email to the patient if one of the following occur has occurred in the past 24 hours: ≥4 hours without CGM signal, ≥2 hours 54 - 70 mg/dl and/or 15 minutes <54 mg/dl. Tele-monitoring call will include questions to find out why the event happened and then suggestions on how to trouble shoot to avoid issues in the future. As this is a feasibility study, statistical considerations were not used.
Children with congenital primary and secondary adrenal insufficiency, who are deficient in cortisol, are at risk for hypoglycaemia, irrespective of appropriate hydrocortisone treatment, which can lead to potentially serious neurological complications. Few series are described in pediatrics. The prevalence of hypoglycaemia is probably underestimated because it is often asymptomatic and capillary blood glucose monitoring is not always performed routinely. The objective of the study is to evaluate the prevalence of hypoglycaemia in children with adrenal insufficiency.
