DIabetes GLycemic Assessment in Newly Confirmed Episodes

This is a prospective, open-label, randomized controlled trial involving 80 adult patients with newly diagnosed T2DM (diagnosed within the last 3 months) recruited at the Bogomolets National Medical University. Participants may be lifestyle-controlled or receiving stable non-insulin anti-diabetic medications. Participants will be randomized in a 1:1 ratio to either the Real-Time Continuous Glucose Monitoring group (CGM group) or the control group (standard Self-Monitoring of Blood Glucose \[SMBG\] using conventional glucometers). The gathered data will help determine whether the real-time visual feedback provided by CGM systems superiorly improves glycemic variability, optimizes metabolic parameters, and enhances patient adherence to lifestyle interventions and pharmacological treatment compared to conventional SMBG methods in the early stages of T2D.

Early GLP-1 Receptor Agonist and SGLT2 Inhibitor Add-On Strategies in Adults With Obesity, Type 2 Diabetes, Cardiovascular-Kidney-Metabolic Syndrome Stage 2-3, and Metabolic Dysfunction-Associated Steatotic Liver Disease

This retrospective observational target-trial emulation uses electronic health record data from the TriNetX US Collaborative Network to compare early treatment intensification strategies in adults with obesity, type 2 diabetes, cardiovascular-kidney-metabolic syndrome stage 2-3, and metabolic dysfunction-associated steatotic liver disease who initiate a GLP-1 receptor agonist or an SGLT2 inhibitor as background therapy. Within each background-therapy cohort, patients who added the complementary class within 90 days of initiation were compared against patients who did not, with prespecified comparisons against both the overall non-complementary cohort and the analytical subset who initiated usual-care add-on therapy (DPP-4 inhibitors, sulfonylureas, or insulin) within the same window. The primary outcome is all-cause mortality over 60 months, with major adverse cardiovascular, kidney, and liver outcomes also evaluated. Propensity-score matching is used to reduce bias from nonrandom treatment selection.

Endoscopic Sleeve Gastroplasty Plus Duodenal pulsENDO for Obese T2DM

This study is designed to evaluate the efficacy, safety, and mechanisms of combining ESG and pulsENDO procedure in obese patients with T2DM

DASH-Obesity: Explainable AI for Family-Centric Personalized Weight Control in Adolescents and Young Adults With Obesity and Chronic Conditions

This prospective single-arm feasibility study evaluates the Adhera Caring Digital Program for Obesity (ACDP-O), a family-centered digital health intervention designed to support adolescents and young adults with overweight/obesity and chronic conditions, including type 1 diabetes (T1D) and asthma. The intervention combines personalized educational content, wearable-device monitoring, psychometric assessments, and explainable artificial intelligence (AI) to improve mental well-being, quality of life, and adherence to healthy lifestyle behaviors. A total of 280 families will participate in a 3-month intervention with remote monitoring and follow-up assessments.

Automated Passive Case-Finding for Advanced Liver Fibrosis in MASLD: The LiverSeek Programme

LiverSeek is a fully automated, passive case-finding programme for advanced liver fibrosis associated with metabolic dysfunction-associated steatotic liver disease (MASLD) in primary care. The programme operates through the Laboratory Information System (LIS; Modulab/Biwer Analytics) of the Clinical Biochemistry Laboratory at Hospital General Universitario Gregorio Marañón (HGUGM), covering approximately 350,000 inhabitants across 11 peri-urban primary care centres affiliated to SERMAS (Servicio Madrileño de Salud) in Madrid, Spain. When a high-risk patient (age 50-75 years with ≥1 of: ALT above ULN + HbA1c ≥6.5%; ALT above ULN + BMI \>30; BMI \>30 + HbA1c ≥6.5%) undergoes a routine blood test in primary care, the LIS automatically calculates FIB-4. If FIB-4 \>1.30, the system reflexively orders ELF and MASEF from the same serum sample, without any action required from the primary care clinician. Patients with a positive second-step NIT (ELF ≥9.8 or MASEF ≥0.33) receive an automatic alert directing them to the Hepatology Advanced Practice Nurse for VCTE (FibroScan) and clinical evaluation. The primary objective is to evaluate the prevalence of hepatic fibrosis in the high-risk population using this single-step automated strategy. Secondary objectives include head-to-head diagnostic comparison of FIB-4+ELF vs FIB-4+MASEF vs FIB-4+FAST for histologically-confirmed endpoints (significant fibrosis ≥F2, advanced fibrosis ≥F3, at-risk MASH), evaluation of the Liver Risk Score, and a health-economic analysis. A sub-study evaluates a nurse-led structured lifestyle intervention in NIT-positive patients.

Dietary Insights and Nutritional Education in Adults on GLP-1 Therapy

This pilot study will evaluate the feasibility, acceptability, and perceived usefulness of the SWITCH mobile nutrition behavioral intervention among adults receiving GLP-1 receptor agonist therapy for obesity and/or type 2 diabetes. Participants will complete baseline assessments, receive a 6-week app-based nutrition intervention consisting of daily dietary self-monitoring and weekly learning modules, and complete follow-up assessments and a structured interview.

Hydration Intervention to Decrease Side Effects Associated With GLP - 1 RA Therapy

This is a 17 - week study consisting of a one - week run - in period and a 16 - week intervention. The 16 - week pilot interventions aims to increase hydration in those beginning GLP - 1 RA therapy. Investigators aim to increase hydration to potentially decrease side effect severity, amount of side effects, and drug discontinuation associated with GLP - 1 RA therapy. The investigators are piloting to assess feasibility and preliminary efficacy of the intervention through examining participant retention, participant feedback, researcher and participant adherence to protocols, impact on hydration biomarkers, and participant reported GLP - 1 RA side effects.

Eating Behaviour Before, During, and After Obesity Medication

This study will examine how eating behaviour changes during the first 18 months of treatment with obesity medications in patients attending the St Vincent's Healthcare Group obesity service. Obesity is increasingly understood as a chronic, relapsing, multifactorial disease that requires long-term management rather than short-term advice alone. Newer anti-obesity medications, particularly glucagon-like peptide-1 receptor agonists and related therapies, have improved weight-loss outcomes and altered the experience of hunger, fullness, food reward, and meal size for many patients. However, while weight reduction is well described in the literature, less is known about how patients themselves experience eating behaviour over time as treatment progresses from initiation to active weight loss and then towards weight maintenance. This study is designed to address that gap by exploring the lived experience of appetite and food-related behaviour across clinically meaningful stages of treatment. The study will use a longitudinal mixed-methods design. Thirty participants aged 16 to 80 years with a body mass index above 27 kg/m2 who are commencing weight-loss medication as part of routine care will be recruited. The sample size includes an allowance for a modest dropout rate over the study period. Participants will be followed at four time points: baseline, approximately 3 months after treatment initiation, around 12 months, and at 18 months, with a visit window of plus or minus 13 days. These time points were selected to reflect distinct phases of treatment. Baseline will capture pre-treatment or very early-treatment experience. Three months is expected to reflect a period of early therapeutic response, when medication effects on appetite may be most noticeable. Twelve months is likely to represent a later phase, when weight loss may be slowing and some patients may be approaching their lowest weight. Eighteen months is intended to capture maintenance or stabilisation, when behavioural changes may differ from those seen earlier in treatment. Data collection will include both questionnaires and semi-structured telephone interviews. The questionnaire component will measure key aspects of eating behaviour, including hunger, fullness, food thoughts, portion size, and palatability. Repeated administration at each study time point will allow changes in these behaviours to be tracked over time. The interview component will provide a richer understanding of how participants describe and interpret their experiences. All interviews will be conducted by one co-investigator using the same core interview guide to ensure consistency. Open-ended questions will allow participants to describe changes in appetite, eating patterns, cravings, meal satisfaction, food preferences, and daily routines in their own words, while additional probing may be used to clarify how these experiences evolve through treatment. Interviews are expected to last 15 to 45 minutes, will be audio-recorded with verbal confirmation, and transcribed for analysis. The central research question is how hunger, fullness, food thoughts, portion size, and food palatability change over time during treatment with obesity medications. The hypothesis is that appetitive and consummatory behaviours will decrease from baseline to an early low point, particularly around 3 months, and may then gradually rise again as treatment continues, before stabilising during a later maintenance phase. This pattern would reflect the possibility that the strongest appetite-suppressing effects occur early, followed by behavioural and physiological adaptation over time. At the same time, the study recognises that patients may not all follow the same course, and individual variation will be an important part of the analysis. Quantitative data will be used to describe behavioural trends across time points, while qualitative data will be analysed thematically to identify recurring experiences, challenges, and adaptations. Integrating these two forms of data will strengthen the study by linking measurable change with patient perspective. The study is expected to provide clinically useful insight into how anti-obesity medications influence the lived experience of eating, and how this may change between the active weight-loss phase and maintenance. By focusing on patient-reported hunger, satiety, food preoccupation, portion size, and palatability, the research may help clinicians better understand when patients need additional support, how expectations can be managed, and what aspects of treatment are most important for long-term success. The findings may also contribute to more personalised obesity care by highlighting the behavioural dimensions of treatment that are not captured by weight change alone.

Aleniglipron Phase 2 in Type 2 Diabetes Mellitus

The purpose of this study is to assess the safety and tolerability of aleniglipron at doses up to 240 mg once daily (QD) in participants with T2DM who are living with obesity (body mass index \[BMI\] ≥ 30 kg/m2) or overweight (BMI ≥ 27 kg/m2).

Dietary Insights and Nutrition Experiences in Adults on GLP-1 Therapy - A Study on Diet Quality Changes in Adults on GLP-1 Therapy

The DINE-GLP1 study aims to understand how people on GLP-1 therapy change their eating habits and what kind of dietary support they need. As more people use GLP-1 medications, there's not much guidance on what they should eat, mostly just focusing on managing symptoms and cutting calories. Since these medications reduce food intake, it's important to ensure the diet is nutritious even with fewer calories to help with long-term weight control and health. Most research has looked at how the body responds to the medication and whether patients take it as prescribed, but not much is known about what patients actually experience, what they think they need, or how they could use additional support. Understanding patients' views can help create better lasting solutions. Note that this study does not provide free GLP-1 medication.

Multicentric Approval Study Trans-Duodenal Barrier for Typ 2 Diabetes With Obesity

Approval study Trans-Duodenal Barrier The goal of this clinical trial is to determin the safety and performance of the newly developed Trans-Duodenal Barrier in adult Tryp 2 diabetic and obese patients. The Trans-Duodenal Barrier is an endoscopic implant which can be placed to the gastric outlet and the upper small bowel by interventional endoscopy. It consists of a 60 cm long foil tube , a transpyloric shaft and and two ringlike balloons to fix it at the pylorus. It will be removed after 6 months via gastroscopy. The main questions it aims to answer are: * Does the Trans-Duodenal Barrier lower the HbA1c of the participants ? * How frequent are adverse side effects related to the device? * How much ist the excessive wight loss of treated patients ? * Show patients with Metabolic assiociated Hepatosteatitis (MASH) improvements in liver elasticity (elastography) ? Researchers implant the Trans-Duodenal Barrier to enclosed patients and follow up them till 4 weeks after explantation. Participants will: * Get the Trans-Duodenal Barrier as an implant for 6 moths * Visit the clinic 3 times in the implant period and once for explant. * Receive a telefon interview 4 weeks after explant

ENDOCARE-SCREEN: Metabolic Liver Dysfunction Screening Study

The ENDOCARE-SCREEN study is a single-center, observational, cross-sectional screening study designed to assess the prevalence, phenotypes, and determinants of metabolic dysfunction-associated steatotic liver disease (MASLD/MAFLD) in adults with components of metabolic syndrome. Up to 10,000 participants aged ≥18 years with overweight, obesity, or metabolic risk factors will undergo standardized screening including a health questionnaire, anthropometric measurements, blood pressure assessment, laboratory testing, and liver ultrasound. The study aims to generate a comprehensive metabolic-hepatic dataset integrating clinical, laboratory, imaging, and lifestyle data. Collected data will be used to identify metabolic and behavioral risk factors for MASLD, characterize disease phenotypes, and support the development of predictive models. The ENDOCARE-SCREEN study will also serve as a qualification platform for selecting eligible participants for a subsequent interventional randomized controlled trial (ENDOCARE-SUPPORT). The study involves minimal risk procedures routinely used in clinical practice and follows ethical principles outlined in the Declaration of Helsinki and Good Clinical Practice (GCP) guidelines.

Fat Around Heart Arteries as a Measure of Inflammation in Patients With Glycometabolic Disease

In this study, the objective is to investigate inflammation in the arteries of the heart. A heart CT scan (CCTA) will be used to measure inflammation by assessing the fat tissue surrounding the arteries of the heart. Participants with and without type 2 diabetes who have no heart symptoms have been examined and had a CCTA scan performed. This study aims to answer the following questions: • Is inflammation in the surrounding fat tissue of the heart arteries associated with the following glycometabolic conditions: I) Obesity ii) Prediabetes iii) Type 2 diabetes

CGM Use in Non-insulin Patients With DM2

The U.S. Food and Drug Administration (FDA) has approved multiple Continuous Glucose Monitoring (CGM) devices from different manufacturers to be used as an aide in patients with type 1 and type 2 diabetes who require medications, and more recently, as over the counter versions for patients with and or without diabetes who want to better understand how diet and exercise may impact blood sugar levels. However robust evidence supporting that CGM is significantly superior to traditional home fingerstick blood glucose monitoring (FSBGM) in this population is lacking. Thus, Medicare and VHA only authorize use of CGM for patients with diabetes who require daily insulin therapy , unless they meet special criteria such as having hypoglycemia or inability to monitor glucose via traditional FSBGM. Objectives Primary Study Aim: Among veterans with uncontrolled diabetes not requiring insulin therapy who are participating in an intensive multidisciplinary program to improve diabetes control (VDOP), to assess whether use of a CGM compared to use of traditional FSBGM results in greater change in hemoglobin A1c upon VDOP completion and up to 12 months. Secondary study aims: To assess whether use of CGM in this population leads to greater improvement in diet, physical activity, and weight loss upon VDOP completion and up to 12 months. Hypothesis The use of a CGM by Veterans with T2DM who do not use insulin will help them improve their diabetes self - management (diet, physical activity, weight) and glycemic control more so than those using traditional fingerstick glucose monitoring. Methods This will be a prospective "open label" randomized controlled trial where participants will be randomly assigned to CGM (intervention group) or FSBGM (control group) during their participation in VDOP. Relevance to Veterans and VA mission Most Veterans with T2DM do not use insulin. It is important for both, these Veterans and the VA, to learn whether this more costly and somewhat burdensome technology supports improvement in diabetes self-management
