Telehealth Educational Intervention for Adults With Type 2 Diabetes in Oman

The goal of this clinical trial is to find out whether adding a nurse-led telehealth educational program to usual diabetes care can improve blood sugar control, medication-related behaviors, and quality of life in adults with type 2 diabetes in Oman. The main question this study aims to answer is whether adults who receive the telehealth educational program, in addition to their usual diabetes care, have better blood sugar control after 6 months than adults who receive usual diabetes care alone. Blood sugar control will be assessed using hemoglobin A1c (HbA1c), a blood test that reflects average blood sugar levels over the previous few months. The study will also examine whether the telehealth program improves participants' attitudes and behaviors related to taking their diabetes medicines and their diabetes-related quality of life. Among participants receiving the telehealth intervention, the study will also assess how easy, useful, reliable, and satisfactory they find the telehealth service. Approximately 160 Omani adults with type 2 diabetes will take part in the study. Participants will be randomly assigned to one of two groups. One group will continue usual diabetes care and will also receive an individual telehealth education session once a week for 24 weeks. Each session will last about 20 to 30 minutes and will be provided by a trained nurse using an approved secure telehealth platform. The sessions will cover topics such as diabetes and HbA1c, safe use of medicines, strategies for remembering medicines, healthy eating, physical activity, blood glucose monitoring, recognition of low and high blood sugar, prevention of diabetes complications, stress and sleep, and communication with healthcare professionals. The other group will continue to receive usual diabetes care without the additional study telehealth education program. No established diabetes care will be withheld from either group, and the telehealth education will not replace routine medical care or authorize the research team to change participants' medications. Participants will be assessed at the start of the study, at 3 months, and at 6 months. Assessments will include HbA1c testing and questionnaires about medication-related beliefs and behaviors and diabetes-related quality of life. Participants in the telehealth group will also complete a questionnaire about their experience with and satisfaction with telehealth.

Effectiveness of Combining Patient Follow-Up With an Educational Intervention on Self-Management Skills of Type 2 Diabetes Mellitus Patients: A Controlled Intervention Study in Primary Care

The purpose of this clinical study is to evaluate whether patient education provided in conjunction with a structured, shared follow-up plan in primary care strengthens the self-management skills of patients with Type 2 Diabetes (T2DM). The study also aims to determine whether the effect of this intervention is associated with patients' baseline levels of health literacy. The key questions this study aims to address are as follows: 1. Do the structured follow-up model and educational intervention improve diabetes self-management skills (healthy lifestyle behaviors, blood glucose management, and use of health services) among patients with T2DM? 2. Can this improvement in diabetes self-management skills occur regardless of patients' baseline levels of health literacy? To measure the effectiveness of structured follow-up in improving diabetes self-management, researchers will compare the intervention group-which receives in-person sessions supported by visual aids-with the control group, which is followed up via standard phone calls. Participants will go through the following processes in the study: Participants in the Intervention Group: For three months, they will attend monthly in-person (or video-based, upon request) follow-up sessions with their family physicians. The first session lasts approximately 45 minutes, the second 20 minutes, and the third 15 minutes. Together with their doctors, they will complete a "Diabetes (DM) ID Card" and receive education on diabetes care and monitoring for complications. At home, they will monitor their own blood sugar levels, perform foot checks, and record this data in the "DM Diary" developed by the researchers. At the clinic, they will undergo screenings for complications such as neuropathy, including foot examinations and the monofilament test, performed by their family physicians. They will review changes in diet and physical activity with their physicians. At the start of the study and at the end of the third month, they will complete self-management and health literacy assessment scales. Participants in the Control Group: For three months, they will receive monthly phone calls from their family physicians lasting approximately 10 minutes, which will include general information about diabetes and reminders about complication screenings (eye, foot, and kidney examinations). Participants will complete the diabetes self-management assessment scale at the start of the study and again at the end of the third month.

HOPE Intervention for Fitness

We will test the HOPE intervention on changing behavior of people to exercise more (take more steps each day).

Improvement Through Movement - Balance Control and Somatosensory Function in People With Diabetes Mellitus Type 2

This study focuses on improving balance control and somatosensory functions in individuals aged 60 years and older with diabetes mellitus tyoe 2 (DMT2). Older adults with DMT2 are at an increased risk of balance problems due to diabetic complications such as neuropathy, retinopathy, and possibly reduced vestibular function. The aim of the study is to investigate whether a 12-week exercise program, with or without additional balance exercises, can improve balance control, enhance somatosensory functions (such as touch and vibration thresholds), and positively impact diabetes-related parameters, including HbA1c levels. The study is designed as a randomized controlled trial (RCT). Participants are selected based on reduced balance control identified in a prior cross-sectional study. The intervention group follows an exercise program in accordance with international guidelines, supplemented with balance exercises supervised by the researcher (physiotherapist). The control group follows the same guidelines but without balance exercises; instead, they perform relaxation exercises. Balance control is assessed both statically and dynamically, while somatosensory functions are measured, and diabetes-related parameters are collected. The intervention is primarily home-based, supported by an activity tracker, but the balance or relaxation exercises are conducted under supervision at a designated location. This study aims to contribute to the quality of life of older adults with DMT2 by reducing balance problems and fall risks.

Evaluation of the Risk of Heart Failure in Patients With Chronic Kidney Disease and Type 2 Diabetes Mellitus

The goal of this study, performed entirely with computer programs, is to learn if using a combination of two drugs works better than using one alone, in the treatment of people with chronic kidney disease and type 2 diabetes mellitus. The main questions it aims to answer are: * How many events of heart failure, heart failure hospitalizations, and cardiovascular death happen in each group? * How do serious kidney problems progress in each of the groups? Researchers will compare reference therapy (finerenone) with a combination of finerenone and empagliflozin. There will not be human participants in this study. With the help of artificial intelligence, researchers will recreate a large population of people with chronic kidney disease and type 2 diabetes mellitus. Data on their disease, treatment, and laboratory parameters will be based on and simulated using real data from previous clinical trials conducted with real participants.

"Screening for Change: Early Risk Detection and Integrated Prevention for Diabetes and Cardiovascular Diseases in the Marche Region"

This study aims to test the feasibility of a new systematic screening program to allow the early detection of individuals aged 50 years at risk of type 2 diabetes mellitus (T2DM) and cardiovascular diseases (CVDs) in the resident in the province of Ascoli Piceno and without previous diagnosis, using the CUORE and FINDRISDC tools developed in the Project. The intervention will be conducted at the premises of the Prevention Department in Ascoli Piceno and San Benedetto del Tronto, within the Local Health Authority of Ascoli Piceno (Marche Region, Italy), throughout 2026. Eligible individuals will be invited, based on recruitment criteria, to the screening via a letter containing study information and participation instructions. Those willing to participate will book the appointment to undergo the screening in one of the two premises of the Prevention Department involved in the study (namely, San Benedetto del Tronto and Ascoli Piceno), through the regional reservation system (CUP). On the scheduled date, participants will visit the Prevention Department, where healthcare professionals (HCPs) will explain the study, obtain the informed consent, and collect data related to the CUORE and/or FINDRISC questionnaires, as well as sociodemographic information. The calculated scores will determine the 10-year risks of T2DM and major CVD events. Based on these risks, participants will be provided with tailored suggested pathways. A summary letter outlining these pathways will be delivered, and, in case of consent, results will be added to the participants' Electronic Health Record. Follow-up calls will be scheduled at 3 (T1) and 6 (T2) months to assess adherence to the suggested pathway (e.g., visit the General Practitioner (GP), lifestyle counselling) through a phone call.

Pre-Diagnosis GLP-1 Receptor Agonist Use and Post-Cancer Mortality in Adults With Obesity and Type 2 Diabetes

This study will examine whether the type of diabetes treatment used before cancer diagnosis is associated with survival and serious complications after obesity-associated cancer in adults with obesity and type 2 diabetes. The study focuses on glucagon-like peptide-1 receptor agonists (GLP-1 RA) and compares them with other commonly used glucose-lowering therapies, including SGLT2 inhibitors, DPP-4 inhibitors, sulfonylureas, metformin, and usual care. Using de-identified electronic health record data from the TriNetX US Collaborative Network, the study will assess whether patients who used GLP-1 RA before cancer diagnosis have different risks of death, hospitalization, sepsis, and other major outcomes after cancer diagnosis. This is an observational study designed to evaluate associations in routine clinical care and not to prove a treatment effect.

Effectiveness of Low-Calorie MIND-HK Diet and Very Low-Calorie Diet on Glycemic Control and Cardiovascular Outcomes in Adults With Type 2 Diabetes: A 12-Week Randomized Controlled Trial

The objective of this project is to assess the effectiveness of a low-calorie and very low-calorie Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND-HK) diet in improving glycemic control and cardiovascular outcomes in adults with T2DM. A total of 180 participants aged 40 to 70, diagnosed with T2DM, will be recruited and randomized into three groups: intervention 1 following the low-calorie MIND-HK diet, intervention 2 following the very low-calorie diet, and an attention control group. The two intervention groups will attend four in-person nutrition counseling sessions (one per week, 60 minutes per session, followed by a 30-minute Q\&A) at a community centre and will use KetoMetrics Breath Ketone System and dietary mobile app, to track diet and monitor daily ketone levels for early signs of ketosis that may lead to diabetic ketoacidosis (DKA). The attention control group will receive an equal amount of attention through four in-person infectious disease counseling sessions. The primary outcome will be HbA1c levels. Secondary outcomes include fasting blood glucose, lipid profile, blood pressure, body mass index, waist circumference, breath ketone, scores from the Summary Diabetes Self-Care Activities (SDSCA) Questionnaire, and MIND diet scores. This study will contribute to the growing body of evidence on dietary interventions for managing T2DM in adults.

Is Serum Irisin Level a Biomarker in Diabetic Polyneuropathy?

Diabetic polyneuropathy is a common complication of type 2 diabetes mellitus associated with sensory impairment and functional disability. Irisin is a myokine that has been implicated in glucose metabolism and neuroprotection. This prospective observational case-control study aims to evaluate serum irisin concentrations in patients with diabetic polyneuropathy compared with diabetic patients without neuropathy and healthy controls, and to investigate whether serum irisin may serve as a biomarker for diabetic polyneuropathy.

AIM-MET: AI-Guided Microbiome-Targeted Nutrition for Glycemic Improvement in Type 2 Diabetes

AIM-MET is a randomized clinical study testing whether a fixed microbiome-targeted nutritional product can improve blood sugar control in adults with type 2 diabetes when used in addition to usual stable diabetes treatment. The study will compare the active nutritional product with a matching placebo over 24 weeks. The product was designed using artificial intelligence before the study began, but the same fixed formulation will be used for all participants assigned to the active group. Artificial intelligence will not be used during the study to make individual treatment decisions, adjust dosing, or personalize the product. The main question is whether participants receiving the active product have a greater reduction in HbA1c, a standard marker of average blood sugar levels, from the start of the study to Week 24 compared with participants receiving placebo. The study will also evaluate early blood sugar changes, fasting glucose, body weight and waist measurements in participants with baseline BMI of at least 25.0 kg/m2, safety, hypoglycaemia events, patient-reported outcomes, and gut microbiome features. This is a 100-participant proof-of-concept study intended to estimate the size of the treatment signal, safety, feasibility, and parameters needed for a future larger confirmatory trial.

Fecal Microbiota Transplantation Intervention on Microbiota Composition and Insulin Sensitivity in Diabetes

The purpose of the trial is to investigate the effect of fecal microbiota transplantation versus placebo on glycemic metabolism and gut microbiota composition in people with type 2 diabetes.

Cut Down on Carbohydrate in the Dietary Therapy of Type 2 Diabetes - The Meal Box Study

The cornerstone in the initial treatment of type 2 diabetes (T2D) is lifestyle modification, involving-among other things-a healthy diet. However, scientific evidence regarding optimal nutrition therapy for patients with T2D is insufficient. This clinical study will examine the effect of a carbohydrate-reduced high-protein (CRHP) diet compared to a conventional diabetes (CD) diet for 12 months on metabolic function and body weight in patients with T2D. The hypothesis of the study is that the CRHP diet will improve metabolic control and the cardiovascular risk profile of patients with T2D to a greater extent than the CD diet. In particular, the expectation is that, compared with the CD diet, the CRHP diet will: * Reduce diurnal and postprandial glycemia measured by continuous glucose monitoring (CGM) and thereby facilitate a significant reduction of glycated hemoglobin (HbA1c) * Reduce body weight * Reduce ectopic fat deposition in the liver and the pancreas * Improve the blood lipid profile * Reduce or not affect blood pressure with no adverse effect on heart rate variability * Increase insulin sensitivity and secretion * Decrease inflammatory markers in the blood * Improve satiety * Reduce or not affect the need for antidiabetic, antihypertensive and/or lipid-lowering medications To reinforce the results and knowledge generated from the primary study, participants will be invited to partake in a 12-month follow-up period after the initial 12 months of intervention.

Re-Engineered Discharge for Diabetes Care Transitions

The goal of this project is to test a novel bedside SDOH screening intervention coupled with post-discharge navigation for hospitalized patients with a diabetes diagnosis to reduce unmet social needs, compared to usual care.

Increasing CGM Use Among Patients With T2D

Study Overview: This interventional study aims to assess whether training healthcare professionals (HCPs) increases the number of continuous glucose monitor (CGM) prescriptions for patients with Type 2 Diabetes in a Federally Qualified Health Center serving a predominantly Hispanic/Latino population. Research Questions: Does HCP training enhance CGM prescription rates in a primary care setting? Does receiving a CGM prescription lead to improved Type 2 Diabetes control, as measured by Hemoglobin A1c levels? What barriers do patients face when prescribed and using CGMs? Given the significant impact of CGMs on diabetes management, this project seeks to improve CGM utilization among eligible patients through a focused intervention for HCPs and evaluate diabetes outcomes for those who do and do not receive a CGM. Methodology: HCPs and staff from three clinics within the same healthcare system will undergo a brief, in-person training on current clinical guidelines and insurance eligibility for CGMs. A booster session will follow about one month later to reinforce learning and address any prescribing challenges. Training efficacy will be evaluated by comparing CGM prescription rates before and after training using electronic health records. HCPs will complete pre- and post-training surveys to assess changes in knowledge, beliefs, and prescribing practices related to CGMs. Additionally, a small subset of prescribers will participate in interviews about their experiences with CGM prescriptions four months post-training. Patient Recruitment and Surveys: Patients with Type 2 Diabetes will be recruited for surveys at baseline, and at 3 and 6 months. These surveys will gather information on their diabetes management experience, levels of diabetes distress, and whether CGM discussions occurred with their primary care provider. Participants who received CGM prescriptions will share their experiences and any barriers encountered. A subset will also be invited for interviews to further explore their CGM experiences. Conclusion: This study seeks to fill a crucial gap in understanding how HCP training influences CGM prescription rates and the associated diabetes management outcomes, ultimately aiming to enhance diabetes care for a vulnerable population.

Photobiomodulation for Diabetic Peripheral Neuropathy

Diabetic peripheral neuropathy (DPN) is a common complication of long-term diabetes, affecting approximately 50 percent of patients. It causes tingling, numbness, and burning pain primarily in the feet, which reduces quality of life. Photobiomodulation therapy (PBMT), also known as low-level laser therapy, is a non-invasive treatment that may improve nerve function by reducing inflammation and promoting cellular repair. This randomized controlled trial aims to evaluate the effectiveness of PBMT in improving nerve function and quality of life in patients with DPN. A total of 36 participants with type 2 diabetes and DPN will be randomly assigned to either a treatment group receiving PBMT (900 nm wavelength, 25W, 1000 Hz frequency) or a control group receiving sham laser therapy. The intervention will be applied to the dorsum and plantar surface of the foot every other day for 6 weeks. Outcomes include pain intensity measured by the Numeric Pain Rating Scale, Neuropathic pain measured by Leeds Assessment of Neuropathic symptoms and signs scale, Nerve function measured by Michigan Neuropathy Screening Instrument and quality of life measured by the NORFOLK QOL DN questionnaire, assessed at baseline and after the intervention period.

The study will include adults with diabetes before surgery who undergo pancreatic surgery as part of routine clinical care at Fondazione Policlinico Universitario A. Gemelli IRCCS. Researchers will study whether glycemic control worsens after surgery and whether this risk changes according to the type of pancreatic resection. The study will also examine changes in glucose metabolism, and cancer-related outcomes. Information from routine clinical care, metabolic tests, imaging, and pancreatic tissue samples collected during surgery may be used for research analyses.

AI-Based Phenome Data Analysis for Predicting the Onset of Major Diseases

This study aims to develop and validate an artificial intelligence (AI)-based predictive model to estimate the risk of incident onset of five major diseases or conditions: cardiovascular disease, type 2 diabetes mellitus, breast cancer, low back pain, and osteoarthritis, in adults aged 30 to 60 years. For each participant, an index date will be defined as the date of a prior health screening or another protocol-defined baseline clinical date. Incident disease status for each target disease or condition will be ascertained by retrospective review of electronic medical records for up to 10 years after the index date. The study integrates retrospective clinical, health screening, laboratory, imaging, and electronic medical record data with prospectively collected biospecimen, proteomic, genomic, questionnaire, lifestyle, and digital health data. Prospective study procedures will be completed over approximately 1 week, with up to 2 additional weeks if needed. By combining multimodal data, this study seeks to improve disease risk prediction and to identify clinical and biological factors associated with disease onset, ultimately supporting personalized risk stratification and preventive healthcare strategies.
