NCT07423884
This study aims to investigate the effect of a low-calorie diet rich in medium-chain triglycerides (MCTs) based on traditional Minangkabau foods on metabolic biomarkers in individuals with obesity. The traditional Minangkabau foods used in this study consist primarily of coconut milk-based dishes, which contain coconut oil as a natural source of MCTs. The metabolic biomarkers assessed include body mass index (BMI), waist circumference, systolic and diastolic blood pressure, body fat percentage, fasting blood glucose levels, lipid profile, leptin concentrations, and DNA methylation of the leptin gene promoter. Based on these metabolic biomarker measurements, participants will be classified into metabolic obesity phenotypes, namely metabolically healthy obesity (MHO) and metabolically unhealthy obesity (MUHO). The researchers hypothesize that the provision of a low-calorie, MCT-rich diet based on traditional Minangkabau foods will have a significant effect on metabolic biomarkers and metabolic status in individuals with obesity.
NCT07416656
The purpose of this study is to examine whether the blood test Hemoglobin A1c (HbA1c) gives an accurate picture of blood glucose levels in patients with inflammatory arthritis who are treated with sulfasalazine. HbA1c is widely used to diagnose and monitor diabetes, but sulfasalazine can shorten red blood cell lifespan and thereby lower HbA1c values independently of actual glucose levels. This may lead to underdiagnosis of diabetes in patients who develop diabetes during sulfasalazine treatment, and to undertreatment in patients with known diabetes due to falsely reassuring HbA1c values. The study aims to answer two main questions: 1. How many patients treated with sulfasalazine have undiagnosed diabetes despite having HbA1c values below the diagnostic threshold? 2. Does HbA1c underestimate actual glucose levels when compared with continuous glucose monitoring (CGM) in patients with sulfasalazine-treated inflammatory arthritis, both in those with known diabetes and those that are not diagnosed with diabetes but have borderline HbA1c values (≥ 38 mmol/mol)?

Examination of individuals with prediabetes and established diabetes for early signs of diabetic retinopathy.
NCT07376850
The TANGO study is a 12-month study involving 120 children and adolescents with Type 1 Diabetes (T1D) across the Czech Republic, Israel, and Poland who use automated insulin delivery (AID) systems. Currently, the global standard for diabetes management is "Time in Range" (TIR), which aims to keep blood sugar levels between 70-180 mg/dL. However, newer technologies like AID systems may now allow for a tighter, more physiological goal called "Time in Normal Glycemia" (TING), which targets a range of 70-140 mg/dL. This study will randomly assign participants to follow either the standard TIR target or the tighter TING target to see if the narrower range improves overall blood sugar control and HbA1c without increasing the risk of hypoglycemia, family stress, or daily treatment burden. By comparing these two approaches, researchers hope to determine if clinical guidelines should be updated to reflect a more precise glucose target for children and adolescents worldwide
NCT07351786
This study aims to test the impact of new-generation anti-diabetic drugs, such as SGLT2 inhibitors and DPP-4 inhibitors, on the development of diabetic retinopathy (DR). The study hypothesizes that these drugs have protective effects in diabetic retinopathy by delaying its incidence compared to older agents (including metformin) only. Early intervention is critical, as treatment options for advanced stages of DR are limited in terms of their ability to restore impaired vision and their high associated costs. By focusing on delaying the occurrence of diabetic retinopathy, the investigators aim to reduce the burden of DR and improve the quality of life for diabetic patients.
NCT07270328
This pilot feasibility and exploratory study, conducted to prepare for a definitive Randomized Controlled Trial (RCT), compares a structured foot-ankle exercise program with a walking exercise program in adults with Diabetes Mellitus (DM). The primary aim is to assess feasibility, including recruitment rate, retention, adherence, data completeness, acceptability, and adverse events, to inform procedures for the definitive RCT. The secondary (exploratory) aim is to obtain preliminary estimates of effects on Diabetic Peripheral Neuropathy (DPN), stress, and obstacles to Diabetes-Related Quality of Life (DR-QoL), Fasting Blood Glucose (FBG), Body Mass Index (BMI), blood pressure, and Ankle-Brachial Index (ABI). Participants were allocated to three parallel arms for 12 weeks: 1. Foot-ankle exercise (education plus printed materials; independent practice 2-3 sessions/day), 2. Walking exercise (education plus printed materials; ≥150 minutes/week, ≥10 minutes/session, avoiding two consecutive non-exercise days), or 3. Active control (education and printed materials). Outcomes were assessed at baseline (day 0), week 6, and week 12. Analyses focus on feasibility metrics against pre-specified progression criteria and on hypothesis-generating estimates of within- and between-group change in neuropathy, stress, and obstacles to DR-QoL; the study is not powered for definitive efficacy. Retrospective registration note: This study was registered retrospectively after participant enrolment had begun and data collection had been completed. This retrospective status is disclosed for transparency; exploratory outcome analyses are interpreted accordingly, and adverse events related to exercise were monitored and reported.
NCT07193979
Diabetes mellitus, one of the major global health problems of the 21st century, is a chronic metabolic disease characterized by dysregulated nutrient metabolism resulting from defects in insulin secretion and action. Patients with diabetes mellitus are more likely to develop chronic periodontitis. A bidirectional relationship between diabetes mellitus and periodontitis has been demonstrated. Dental complications of diabetes mellitus include periodontitis and dental caries. Dental caries, resulting from tooth demineralization, are more prevalent in diabetic individuals than in non-diabetic individuals. For adults, HbA1c levels were defined as \<7% ("good" control), HbA1c levels between 7% and 8% as "inadequate" control, and levels above 8% as "poor" control. In the study conducted by the investigators, patients diagnosed with type 2 diabetes mellitus and those diagnosed with periodontitis were grouped according to HbA1C levels, and the relationship between these levels and the stage/degree of periodontitis and the degree of caries was examined. Although studies on periodontal diseases and dental caries among adults with type 2 diabetes mellitus exist in the literature, no study has, as far as is known that classifies HbA1c levels in patients with controlled and uncontrolled diabetes diagnosed with periodontitis and explains the relationship between these groups and the stage/degree of periodontitis and the degree of caries.
NCT07155993
This study explores what happens in the body and wellbeing during and after a period of long-term fasting. At the Buchinger Wilhelmi Clinic, participants follow a medically supervised fasting program lasting five or more days, followed by a structured food reintroduction phase. The study observes participants over time to better understand how fasting and the return to eating affect weight, metabolism, nutrition habits, and overall well-being. All participants will complete online questionnaires during the fasting phase and for up to three months afterward. These surveys help track changes in lifestyle, mood, and health. In addition during the first two weeks after fasting ends participants wear a continuous glucose monitor (CGM) to track blood sugar levels in real time, use a mobile app to document meals with photos, and perform simple at-home blood tests using dried blood spot (DBS) kits. By combining digital tools with personal reports and at home tests, the study aims to gain a clearer picture of how the body adapts after a prolonged fast. The goal is to better understand the short- and medium-term effects of extended fasting on metabolism, diet, and well-being-and to provide practical guidance for those interested in fasting as a health practice.
NCT07163000
This study is looking at people with diabetes (type 1 and type 2 diabetes) to see how well a short questionnaire, called the ACT, can identify nerve damage in the feet and legs (also known as peripheral neuropathy). The investigators will compare the ACT questionnaire to other commonly used tools (the DN4 and Michigan Neuropathy Screening Instrument) and to an eye-test that detects small nerve fibers in the eye (called corneal confocal microscopy, or CCM). The main goal is to find out if the ACT questionnaire is accurate in detecting nerve damage and painful nerve damage caused by diabetes. The investigators will also look at whether changes in blood sugar levels, measured with a continuous glucose monitor (Freestyle Libre 3 and iCan), are linked to nerve pain and small nerve fiber damage.
