Glucose, Understanding, Integrated Digital Health, and Engagement (GUIDE) Study

The purpose of this study is to evaluate whether an Integrated Digital Health (IDH) intervention with and without healthcare provider engagement, improves glycemic control and diabetes-related outcomes among adults with Type 2 diabetes. The study will also assess the feasibility of integrating this approach into routine primary care to support personalized, data-informed diabetes management.

Effect of Hyperglycaemia and Moxifloxacin on QTc Interval in T2DM

Diabetes is a significant risk factor for sudden cardiac death, with the QTc interval on electrocardiograms (ECGs) often prolonged in diabetic patients due to factors such as hyperglycaemia and insulin resistance. Drugs like moxifloxacin can further exacerbate this effect, especially in those with diabetes. A previous trial on Type 1 diabetes suggested that hyperglycaemia and moxifloxacin have additive effects, prompting an investigation into whether similar effects occur in Type 2 diabetes (T2DM), particularly in individuals with high insulin resistance. This study aims to evaluate whether moxifloxacin-induced QT-prolongation is amplified by elevated blood glucose levels or insulin deficiency in T2DM patients, considering potential differences between sexes. Blood biomarkers will be analysed to understand the underlying molecular mechanisms. The trial will involve at least 24 male and female participants with insulin-resistant T2DM, aged 18 to 64 years, conducted at Richmond Pharmacology Ltd. Participants will receive treatments with glucose, moxifloxacin, and placebos while closely monitored for side effects during an inpatient stay, followed by outpatient appointments.

Lifestyle Interventions for Expectant Mothers (LIFE-Moms Phoenix) - Phoenix

Background: \- LIFE-Moms (Lifestyle Interventions for Expectant Moms) is a national project that is studying pregnant women who are overweight or obese. It is looking at ways they can manage their weight gain in pregnancy and how this may affect them and their babies health at birth and through the first year. Researchers want to recruit pregnant women who are being treated at the Phoenix Indian Medical Center. They will participate in a two-part study. Objectives: \- To study pregnant women who are in the LIFE-Moms project at the Phoenix Indian Medical Center. Eligibility: * Pregnant women at least 18 years of age who are overweight or obese. * Participants must be receiving care at the Phoenix Indian Medical Center. * Participants must be having only one child in their pregnancy (no twins or other multiple births). Design: * This study will have two parts. The first part will have three visits to obtain data about health early in pregnancy. It will also let participants and researchers find out if the participants are eligible and should continue in the second part of the study. In the second part, participants will be monitored throughout their pregnancy and during the first year after the baby s birth to test the effects of a lifestyle intervention to control weight gain during pregnancy. * On the Part 1 study visits, participants will have a physical exam and medical history. They will provide blood, urine, hair, and other samples to be examined for possible genetic conditions. * For the Part 2 study visits, participants will be placed in one of two treatment groups. Each group will receive the same prenatal and postnatal care that they would get if they did not join the study. * The first group will have a lifestyle intervention program. They will spend about 2 hours every week with other members of their group to learn diet and activity behaviors that may help with their health. * The second group will have an enhanced care program. They will be given additional information about health and pregnancy and be invited to attend three classes to learn about staying healthy during pregnancy.

An Online Lifestyle Program With an AI Lifestyle Coach and Continues Glucose Monitoring in Type 2 Diabetes.

The aim of this study is to evaluate the feasibility and effectiveness of a remote personalised lifestyle program in individuals with T2D. Outcomes will be assessed at the start and after 3, 6, and 12 months with two follow-up measurements (18 and 24 months) to determine whether participation in this re-mote lifestyle program leads to improvements in health and diabetes-related outcomes.

Changing Outpatient Diabetes Care With Remote-Patient-Monitoring: A Real World Evidence Study With Pre-Post Comparison

The goal of this observational pre-post study is to evaluate a remote-patient-monitoring-system (RPM-system) integrated within an electronic health record (EHR) system in a real world cohort of approximately 12.000 people with diabetes in an outpatient care setting. The main question it aims to answer is: Whether glycemic outcomes following integration of the RPM system into the EHR over a two-year period are non-inferior compared with outcomes observed prior to an ambulatory care restructuring (including a prototype of the RPM-system) in October 2024. Participants are included in the RPM-system as part of their regular medical care for diabetes.

Artificial Intelligence-assisted Insulin System in Type 2 Diabetes in General Wards

Our study was a single-blind, randomised, controlled, multicentre study. The study was planned to enrol 142 patients with T2DM admitted to general wards who required subcutaneous insulin therapy. Participants were randomly divided into two groups in the ratio of 1:1, one group with an artificial intelligence-assisted insulin decision system to adjust insulin doses for blood glucose control, and the other group received clinician-instituted insulin dose adjustments for blood glucose control. The effectiveness and safety of the system was confirmed by comparing the glycaemic control and risk of adverse events between the two groups.

Dulce Digital 2.0 - Innovative Diabetes Self-Management in the Digital Age

The proposed research, "Dulce Digital 2.0," will evaluate two mHealth adaptions of Project Dulce that are designed to improve digital health literacy, increase underserved individuals' capacity to access and engage with vital digital health information, and in turn, improve clinical and behavioral outcomes in at-risk adults with diabetes. Expanding access to care in populations faced with challenges of low socioeconomic status and health literacy is a step toward reducing health disparities and positively affecting care. The literature shows that identifying which groups of participants are most likely to benefit from telehealth interventions is an important factor in improving the evidence base for digital health literacy. Dulce Digital 2.0 is highly scalable once the technical infrastructure is built. More importantly, by helping to reduce existing inequities in access to diabetes care and accurate digital health information the model could help to improve health outcomes on a larger scale. The use of digital technology in the delivery of healthcare interventions is increasingly common. Barriers to engagement in digital technology exist among those in underserved populations due to language, access to equipment and internet, education level, exposure to and comfort with technology, and pre-existing deficits in health literacy. The proposed research will investigate the effectiveness of two digital approaches to improving the self-management and digital health skills of underserved participants with diabetes compared to tradition in-person self-management education: 1) live self-management education, traditional in-person classes; 2) live self-management education using a telehealth distance learning platform; and 3) a series of text-based messages, not requiring a smart phone or internet connection, that encourage healthy self-management behaviors.

Effect of the Thrive AI Health App on Lifestyle Behaviors and Quality of Life

The goals of this randomized trial is to learn: 1. If the Thrive AI Health app will help adults improve their everyday habits (diet, exercise, and sleep). 2. How often participants will use the Thrive AI Health app to which they will have free access The Thrive AI Health app uses artificial intelligence (AI) to give personalized advice. It is designed to help people eat better, exercise more, manage stress, and sleep well. Researchers will compare changes in diet, exercise and sleep in participants using the app to those participants not using the app. Participants will complete study questionnaires and an in-person visit at the beginning and end of the study.

Evaluate the Efficacy of an Oral Health Behavioral Intervention in People With Diabetes

The purpose of this clinical study is to evaluate the effect of a behavioral intervention on the number of preventive and treatment dental claims in a population of people with Type 2 Diabetes.

Impact of a Community Health Worker Strategy on Produce Prescription Program Uptake Among People With Diabetes

Produce prescription programs (PRx) are promising interventions for improving health outcomes for patients with both type 2 diabetes (T2D) and food insecurity, but uptake has been suboptimal. There is a critical need for scalable, evidence-based implementation strategies for improving PRx uptake and optimizing the effectiveness and cost-effectiveness of these interventions. This study will co-design and pilot a community health worker (CHW) strategy and test the effectiveness of the strategy compared to PRx participants without a CHW. The overall objective of this study is to test and evaluate a theory-informed, user-centered community health worker (CHW) implementation strategy to improve uptake of a PRx, among Hispanic Medicaid-eligible patients with T2D in Connecticut (CT). CHWs will offer participants personalized support by overcoming barriers and leveraging facilitators to PRx uptake.

Enhancing Diabetes Management Approaches for Patients With Uncontrolled Diabetes

The purpose of the study is to learn about the best way to enhance pharmacy-related care for diabetes self-management. This research is being done because we want to improve use of medicines and diabetes management among adults with type 2 diabetes and find out which of type of support may improve diabetes self-management for adults. Participants will be assigned to one of 4 groups, and will either: * receive care as usual; or, * receive added medicine management support from a pharmacist; or, * receive support from a Community Health Worker (CHW) to address life challenges; or, * receive both the pharmacist medicine management and the CHW support

Home-based Interventions for FrAilty preveNTion in AdultS With DIabeTes and Chronic Kidney Disease

One of the most common problems in people with diabetes (DM) and chronic kidney disease (CKD) is the high frequency of other coinciding medical conditions such as osteoporosis and frailty. Frailty in particular is very common in adults with DM and CKD and it can result in significant muscle weakness which can result in increasing difficulties with performing activities of daily life (ADL). This can lead to an increase risk for falls, bone fractures and increasing hospitalization. The investigators have showed that adults with DM and CKD who have frailty use hospital services more frequently, have reduced quality of life and difficulties with performing their ADLs1. There is some evidence that early screening for frailty and lifestyle interventions that focus on healthier eating and physical activity can help prevent frailty from getting worse. The study purpose is to develop and test a home-based lifestyle intervention program focused on optimizing diet and the ability to perform your ADLs in adults with DM and CKD. The goal of this program is to ensure that adults with DM can live healthier lives within the community.

Problem-Solving Therapy for Patients With Chronic Disease and Poor Mental Well-being in General Practice

In Denmark the vast majority of patients with chronic ischemic heart disease and/or type 2 diabetes are managed in general practice. 20% of the patients suffer from poor mental health. Problem-solving therapy (PST) is a psychotherapeutic method that is proven effective in adults with poor mental health. PST can be provided in general practice. The main objective of this study is to test effectiveness of providing PST to this group patients.

Canagliflozin Targeting Vascular Inflammation

CANTOR SING is a pilot single center double blinded randomized study. The investigators will compare the effect of canagliflozin (300 mg daily - intervention arm) vs. placebo (control group) on the FDG aortic uptake in patients with stable CAD (over 60 days post-myocardial infarction) after a 6-month period of treatment. The investigators plan to enroll 8 patients in each arm (total sample size: 16 patients). Primary endpoint is the change in FDG aortic uptake between baseline and 6 months in each arm.

Continuous Glucose Monitoring (CGM) in an Underserved Population

The investigators aim is to conduct a randomized clinical trial in an underserved population who are either uninsured or on Medicaid and taking at least one injection of insulin daily. The investigators believe that this study will lead to considerable alleviation of health disparities and provide better care for an underserved population. This will be a pilot study to evaluate the feasibility of such a trial in this population before doing a larger multicenter trial.

The Association Between Cognitive Function and Neuropathy in Individuals With Type 2 Diabetes

The goal of this observational study is to evaluate whether individuals with different types of diabetic neuropathy (peripheral and cardiovascular autonomic neuropathy) are at an increased risk of cognitive impairment and to investigate the potential reasons for this association. The primary research question is: Is diabetic peripheral and cariovascular autonomic neuropathy in type 2 diabetes associated with cognitive decline? To address this question, the study will include individuals with and without type 2 diabetes. All participants will undergo comprehensive neuropathy assessments, neuropsychological evaluations and blood biomarker analysis. In addition, some individuals will undergo structural and functional brain MRI.

Deploying Digital Prosthetic Interface Technology and Exercise in Dysvascular Amputees

The study will test a new approach to the design and implementation of socket and liner technology in individuals who lost a lower limb secondary to diabetes mellitus type II (herein referred to as dysvascular amputees). The technology-based intervention will be combined with an exercise program designed to improve the health status of dysvascular amputees.

Enhancing Diabetes Care by Treating Insomnia

Insomnia is highly prevalent in individuals with type 2 diabetes (T2D) and is associated with poor glycemic control. Louisiana has one of the highest diabetes prevalence rates in the U.S., with significant disparities by race, income, and rural residence. Despite growing recognition of sleep's role in diabetes management, sleep disturbances remain largely unaddressed in diabetes care. Cognitive behavioral therapy for insomnia (CBT-I) is the first-line treatment for chronic insomnia, yet it is underutilized in primary care clinics such as federally qualified health centers (FQHCs) that serve high-risk populations. The long-term goal of this research is to improve cardiometabolic health and reduce diabetes disparities by integrating sleep interventions into diabetes care. This pilot study aims to: (1) evaluate the impact of CBT-I on sleep and diabetes-related outcomes, and (2) assess the acceptability, feasibility, and fidelity of implementing a 6-week CBT-I program in an FQHC setting. The investigators will conduct a randomized controlled trial (RCT) with 30 FQHC patients (aged 40+) with uncontrolled T2D (HbA1c \>7%) and comorbid insomnia (Insomnia Severity Index (ISI) score ≥15). Participants will be randomly assigned to either the CBT-I intervention or usual care. Sleep (ISI scores, actigraphy) and cardiometabolic (HbA1c, fasting glucose, insulin) outcomes will be assessed at baseline and three months post-randomization. Implementation success will be evaluated using fidelity, feasibility, and acceptability measures. Findings will provide preliminary evidence for integrating CBT-I into primary care, informing larger trials to improve diabetes outcomes and reduce disparities in Louisiana.

Evaluation of Pharmacist Intervention for Individuals With Uncontrolled Type 2 Diabetes

Type 2 diabetes is a chronic disease that can lead to a number of complications if uncontrolled and there is a projected increase of 33% patients living with diabetes over the next 10 years. There can be improvements to modifiable risk factors such as diet and exercise, in addition to medications. Treatment often involves a multidisciplinary approach with a physician, endocrinologist, dietitian, pharmacist and other support health professionals as required. This study will evaluate the effects of the pharmacists (or pharmD interns) intervention, looking at changes to the patients HbA1C, which is a measure of the patients blood glucose control over the previous 3 months as well as the patients understanding and comfort with managing their own diabetes via participant survey.

Pregnancy and Postpartum Breastfeeding Support for Patients With Gestational Diabetes

The investigators will use implementation methods to develop better breastfeeding support for patients with gestational diabetes as a way to prevent type 2 diabetes.

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

Digital Support for Reducing Salt Intake Among Patients With Diabetic Kidney Disease: Protocol for a Controlled Clinical Trial

This study evaluates whether a digital patient education program can improve adherence to KDIGO 2022 dietary recommendations (low sodium and optimal protein intake) among patients with type 2 diabetes and chronic kidney disease (eGFR 30-59 ml/min).

Enhancing Digitally Delivered Diabetes Education With Real-Time CGM

The current research study will add continuous glucose monitoring devices to the evidence-based text messaging diabetes education program for patients with type 2 diabetes for 6 months. Results on the effectiveness of this intervention will be compared for non-insulin using patients.

Disentangling the Effect of Brain Insulin Resistance on Brain Health

People with diabetes are at increased risk of developing dementia, including Alzheimer's disease and vascular dementia. In addition, persons with diabetes have more pronounced age-related brain atrophy and cognitive difficulties compared to people without diabetes. The mechanisms behind the effects on the brain of diabetes are still unclear. New research suggests that the brains of some people with diabetes do not respond normally to insulin signals, a condition known as brain insulin resistance (BIR). To date, there have been no large clinical studies investigating BIR and its impact on brain health, but several smaller studies suggest that BIR may be a cause of cognitive decline and impaired brain health in people with diabetes. Another mechanism that may contribute to impaired brain health in people with diabetes is damage to the blood vessels in the brain. Damage to blood vessels is a well-known complication of diabetes, but how it affects the brain is not fully described. In this project, we will investigate the relationship between BIR and brain blood vessel dysfunction and its relationship to cognition and brain function. This is done by examining patients with type 1 diabetes (T1D), type 2 diabetes (T2D) and healthy controls. The participants will undergo MRI brain scans to assess the impact of BIR on the brain physiology and to evaluate brain blood vessel health. Participants will undergo comprehensive assessments of their cognitive abilities and thorough health examination.
