A Study of Glycemic Control in Left Ventricular Assist
The study is being conducted to understand if the hemoglobin A1c, a measurement of control of blood sugars over a 3-month time, is valid in patients with Left Ventricular Assist Devices (LVADs) in place. To understand whether it is an adequate measurement, the investigators will compare the A1c to results from a continuous glucose monitor (CGM) measurement of blood sugars. By monitoring blood sugars continuously, the investigators will also assess whether they can get better control of blood sugars with a CGM, including avoiding low blood sugars.

Effect of Zinc on Glucose Homeostasis
The purpose of this investigation is to evaluate the impact of zinc supplementation on fasting glucose levels, hemoglobin A1c (HbA1c), and other indices of glucose homeostasis in individuals with prediabetes. The investigators hypothesize that prediabetic subjects receiving zinc will demonstrate a greater decrease in HbA1c and blood glucose compared to prediabetic subjects receiving placebo. Specific Aim: Conduct a prospective, double-blind randomized clinical trial comparing the effects of 12 months of zinc supplementation (zinc gluconate 30 milligram \[mg\] per day) versus placebo on glucose homeostasis. Based upon expected effect size and power calculations, and anticipating a 20% drop-out rate, the investigators will study 200 prediabetic subjects (100 per group) using a 1:1 randomization design. HbA1c, fasting plasma glucose, and other measures will be obtained at 0, 6, and 12 months and will be compared between zinc supplementation and placebo groups.

Diabetes Electronic Prompt for Improved Care Coordination and Treatment in the ED
The goal of this clinical trial is to improve the processes of Type 2 Diabetes (T2D) care coordination and treatment in the emergency department (ED) by utilizing clinical decision support mechanisms in the electronic health record (EHR). The main question is whether electronic prompts triggered by hyperglycemia and elevated A1c results in providers providing earlier treatments and faster time to subsequent primary care appointment and greater reduction in hemoglobin A1c (HA1c). ED clinicians will receive alerts called Our Practice Advisories (OPA's) through the EPIC EHR. The 1st OPA triggers when a random point-of-care (POC) glucose is ≥250 mg/dL, prompting a suggested additional HA1c order. A 2nd OPA triggers if the resulting HA1c is ≥10%, prompting consideration of further care coordination in the Observation Unit. Investigators will compare the outcomes post-intervention compared to pre-intervention.

CGM-Assisted Management of PN
The purpose of this study is to learn more about changes in glucose levels in hospitalized infants with intestinal failure receiving parenteral nutrition or PN (nutrients delivered intravenously), as they transition from continuous PN (given 24 hours a day) to cycled PN (given less than 24 hours a day). There is an increased risk of glucose abnormalities with cycled PN, which can be harmful to infant growth and brain health. Continuous glucose monitors (CGM) will be used to measure interstitial glucose levels (in the tissue under the skin), which are similar to blood glucose levels. CGM is a small, minimally-invasive sensor worn on the thigh, which gives a glucose measurement every 5 minutes, and can help us understand changes in blood sugar levels without having to do a blood draw or fingerstick. CGM will be used during PN cycling for up to 30 days or until hospital discharge. If target GIR cycled PN is not reached following 3 sensor periods (up to 10 days per sensor), the parent/guardian will be approached to accept or decline participation in an optional extension phase. In the extension phase, the primary study will be repeated and CGM monitoring will continue until target GIR cycled PN is reached, up to an additional 3 sensor placements. CGM data will be hidden from the clinical team, there will be no change to routine clinical care. CGM may provide false low glucose readings when the tissue around the sensor is compressed (compression lows), such as when laying on the sensor during sleep. We will generate data during the study to help identify and filter the final dataset to remove likely compression lows. This study may help us understand how cycled PN affects glucose levels in infants with intestinal failure, which may help other children treated with cycled PN in the future.

CGM-Based Glycemic Analysis After ESI
The goal of this clinical study is to learn how blood glucose levels change after an epidural steroid injection (ESI) with dexamethasone in adults. It will specifically compare the glycemic response between patients with type 2 diabetes and those without diabetes. The main questions it aims to answer are: Does the injection cause higher or longer-lasting blood glucose elevation in diabetic patients compared to non-diabetic patients? How do the mean glucose level and Time in Range (TIR) change after the injection in both groups? Researchers will compare a Type 2 Diabetes group to a Non-Diabetes group to see the differences in glycemic fluctuations using a continuous glucose monitoring (CGM) device. Participants will: * Wear a small CGM sensor on their arm for about 15 days to monitor blood glucose levels continuously * Receive an epidural steroid injection containing 5 mg of dexamethasone on Day 3 * Visit the clinic 3 times (Day 1, Day 3, and Day 15) for sensor attachment, the injection procedure, and data collection

Standardized Italian netwoRk Enrolling iNdividuals With Islet-Autoantibodies
This project characterizes the longitudinal progression of children and adults who have tested positive for one or more islet cell autoantibodies across the early stages of type 1 diabetes (T1D). Despite advances in screening, limited evidence exists on how clinical, metabolic, and immunological markers evolve over time and predict progression to symptomatic disease. Using a screened cohort, participants are followed for up to 10 years with repeated standardized assessments. The study evaluates whether population-based screening can reduce diabetic ketoacidosis (DKA) at diagnosis and identify early predictors of progression to clinical T1D. Results are expected to improve risk stratification, inform surveillance strategies, and guide the timing of preventive interventions, with implications for clinical practice and health policy.

CGM in Acute Ischemic Stroke
The goal of this randomized clinical trial is to evaluate whether continuous glucose monitoring (CGM) can be used to guide glucose management in patients with type 2 diabetes who are admitted with an acute ischemic stroke and undergo endovascular therapy. Hyperglycemia frequently occurs during hospitalization in stroke and is associated with worse neurological and clinical outcomes. In current clinical practice, glucose levels are monitored using intermittent point-of-care testing (POCT) with finger-prick measurements, which may miss clinically relevant glucose fluctuations. CGM provides continuous glucose measurements and may allow earlier detection of hyperglycemia and more timely glucose management. This study is designed as a non-inferiority randomized controlled trial comparing CGM-guided glucose management with standard POCT-guided glucose management. The primary objective is to determine whether CGM-guided glucose management is non-inferior to POCT-guided management in terms of percentage time spent in hyperglycemia (glucose \>10 mmol/L) during the first 72 hours of hospitalization. Researchers will compare CGM-guided glucose management to POCT-guided glucose management to evaluate whether CGM can be used as an alternative strategy to guide glucose control in hospitalized stroke patients. Participants will: * Be randomly assigned to either CGM-guided glucose management or standard POCT-guided glucose management * Have their glucose levels continuously monitored (blinded in the POCT-guided group) during hospitalization * Receive glucose management according to the assigned monitoring strategy, based on the hospital insulin protocol

Shunt-dependency After aSAH - Role of Early Hyperglycaemia in CSF and Blood
The goal of this study is to confirm the association of early increased glucose levels in cerebro-spinal fluid (CSF) and ventriculo-peritoneal-shunt (VPS)-dependency also evaluating the influence of blood glucose on VPS dependency in patients suffering from an aneurysmal subarachnoid haemorrhage (aSAH). The main questions we aim to answer are: * Is there an association of glucose levels on VPS dependency in patients requiring extra-ventricular-drain (EVD) placement for aSAH? * In addition, if there is, what is the influence the course of glucose levels has on VPS dependency? Glucose levels in CSF and serum will be measured on admission, or in case of CSF, upon EVD placement. Glucose in CSF will then be measured every day until EVD removal together with serum glucose. Follow-up will be conducted in person after 3 and 6 months.

Effect of Probiotics Versus Metformin on Glycemic Control, Insulin Sensitivity and Insulin Secretion in Prediabetes.
Pre diabetes (PD) is a term that refers to alterations in blood glucose levels, including impaired fasting glucose (IFG), impaired glucose tolerance (IGT) or both, and increase in glycated hemoglobin (HbA1c), all this factors involving a higher risk to develop type 2 diabetes mellitus (T2DM). The efficacy of pharmacotherapy in the prevention of diabetes in adults with pre diabetes has been demonstrated, the first line of pharmacology treatment is metformin, on the other hand, probiotics administration has been reported to be one of the most widely used approaches to modulate the gut microbiota and subsequently prevent or delay the incidence of T2DM. Probiotics are live microorganisms which when administered in adequate amounts confer a health benefit on the host. Has been demonstrated the hypoglycemic effects of the probiotics in different clinical trials in type 2 diabetes mellitus and pre diabetes, but no yet compared with metformin, for this reason comparing it´s activity against metformin in pre diabetes would provide impact information on a new alternative treatment compared with the standard pharmacological treatment. The aim of the study is evaluate the effect of administration of probiotic versus metformin on glycemic control, insulin secretion and insulin sensitivity in patients with pre diabetes.

Early Investigation of Glucose Monitoring After Gestational Diabetes Pilot
One third of women with gestational diabetes (GDM), diabetes diagnosed during pregnancy, have abnormal glucose levels within 3 years after pregnancy, but follow up is low. Continuous glucose monitors (CGM), a small sensor inserted under the skin, may be able to screen women with GDM for diabetes risk. The investigators will ask postpartum women to use CGM at 6-8 weeks postpartum and answer surveys about quality of life after wearing the CGM. The investigators will collect data on blood glucose trends for future studies if participants find CGM use acceptable. The investigators hope to learn if CGM could improve postpartum follow up experiences for people with recent GDM.
