Filter by:The knowledge of the pathogenesis of retinal affections, a major cause of blindness, has greatly benefited from recent advances in retinal imaging. However, optical aberrations of the ocular media limit the resolution that can be achieved by current techniques. The use of an adaptive optics system improves the resolution of ophthalmoscopes by several orders of magnitude, allowing the visualization of many retinal microstructures: photoreceptors, vessels, bundles of nerve fibers. Recently, the development of the coupling of the two main imaging techniques, the Adaptive Optics Ophthalmoscope with Optical Coherence Tomography, enables unparalleled three-dimensional in vivo cell-scale imaging, while remaining comfortable for the patients. The purpose of this project is to evaluate the performance of this system for imaging micrometric retinal structures.
Open label, mechanistic, single-arm study to evaluate the natriuretic effect of 2 weeks dapagliflozin treatment in T2DM patients with impaired renal function. It will measure the average change in 24-hr sodium excretion from average Baseline to average values at Day 2 to 4 within the study group. The study will allow for an up to 6-week Screening and Run-in Period, a 2-week Treatment Period and a 5-day Follow-up Period. Patients will consume food from standardized food boxes starting on Day -6 (patients not on insulin) or Day -20 at the earliest (patients on insulin) of the study until Day 18 (inclusive). Eligible patients will receive dapagliflozin 10 mg tablets once daily for 14±1 days starting on Day 1. This will be followed by a Follow-up Period of 5 days.
The first aim of this study is to describe maternal hormonal and inflammatory changes during pregnancy in women that differ metabolically (limited to women with type 2 diabetes, gestational diabetes and/or overweight). The second aim of this study is to examine maternal hormonal, inflammatory and metabolic factors associated with insulin sensitivity in human pregnancy.
The goal of the trial is to measure pancreatic uptake of 68Ga-NODAGA-exendin by PET/CT for detection of intra-individual differences in beta cell mass before and after treatment with Verapamil.
Type 2 diabetes (T2D) mellitus is a challenge for health care systems as the numbers increases constantly. In 2014, 422 million people had been living with diabetes worldwide. The absolute numbers of people with prediabetes have also grown substantially over 25 years worldwide. In Germany, about 10% of the population has T2D and another 21 % of the population has prediabetes.Overall, 16% of all deaths in Germany are attributable to type 2 diabetes. Macro- and microvascular complications of diabetes imply a significant threat for the patients and are already present in the prediabetic state. Short term and long term complications, the burden of treatment, and reduced quality of life are major burdens of the disease. Accumulating data indicate that currently recommended therapeutic diet regimens in patients with obesity and diabetes are not sustainable on the long term. Novel concepts are therefore urgently needed. T2D occurs when insulin secretion from pancreatic beta-cells cannot sufficiently be increased to compensate for insulin resistance. Causes of beta-cell dysfunction are heterogeneous. In addition, the most important determinants of diabetes remission are the extend of weight loss and restoration of beta-cell function. In the course of diabetes progression, the inability to recover insulin secretion might identify the state of no return to normal glucose tolerance. It is therefore crucial to improve insulin secretion in treatment and prevention of diabetes. Up to now lifestyle intervention trials in prediabetes or pharmacological intervention trials in diabetes did not show improvement of insulin secretion after intervention. However, one recent small human trial shows that intermittent fasting (early time restricted fasting) is able to improve insulin secretion.Currently, there are no trials that examine the effect of intermittent fasting in individuals with a broad range of impaired glucose metabolism (from prediabetes to diabetes). Recently novel subtypes of diabetes and prediabetes with high risk for the early manifestation of diabetes complications have been identified. Currently, prevention strategies for this high risk individuals have not been examined yet. We will study for the first time the effectiveness of 4 weeks intermittent fasting on changes in insulin secretion capacity in subphenotypes of diabetes and in prediabetes.
Diabetes mellitus (DM) increases susceptibility to Tuberculosis (TB) and worsens TB patient outcomes. The number of patients with combined TB and DM now outnumbers that of combined TB and HIV and it has been estimated that 15-30% of TB disease may be attributable to diabetes globally. This may be expected to rise substantially as DM prevalence increases. Treatment of Latent TB Infection (LTBI) in this population will likely have a significant clinical benefit. Similar to HIV-infected individuals, those with DM might benefit from therapy to prevent the development of TB disease. Current international guidelines do not recommend LTBI management in people with DM, but this is because no studies have examined the risk-benefit ratio of such an intervention. To date, no RCTs have been conducted to investigate the efficacy and safety of preventive treatment of LTBI in DM patients. Based on evidence on effectiveness, safety, and treatment completion rates, 3HP has been selected as the regimen of choice for this study of African people living with DM. People living with DM will be randomized to 3HP or placebo to determine the efficacy of 3HP in the prevention of TB disease in this population. PROTID's preventive treatment of LTBI among people with DM will generate the first solid evidence to support or refute the use of preventive treatment against TB in people with DM.
This study compares 2 medicines for type 2 diabetes: semaglutide (new medicine) and a dummy medicine (placebo). Semaglutide will be tested to see how well it works compared to the dummy medicine. The study will also test if semaglutide is safe in children and teenagers. Participants will either get semaglutide or the dummy medicine - which one is decided by chance. Participants will take 1 tablet of the study medicine every morning on an empty stomach. They have to wait 30 minutes before they eat, drink or take any other medication by mouth. The study will last for about 1 year and 3 months (66 weeks). Participants will have 12 clinic visits and 8 phone calls with the study doctor. At all 12 clinic visits, participants will have blood samples taken. Participants will also be asked some questions.
The study aimed to evaluate the effect of SARS-COV-2 infection on metabolic status in patients with diabetes mellitus. Patients' HbA1c levels before and after SARS-COV-2 infection will be evaluated.
All hospitalised patients with COVID-19 who have positive RT-PCR for SARS-COV-2 will be included in the study. The patients will be divided into two groups, as diabetics and non-diabetics. The COVID-19 patients' medical records will be evaluated and compared in terms of the duration of hospitalization, the presence of lung involvement in Computerised Tomography, the need for intensive care unit and mortality rates in patients with and without diabetes.
This is a multi-center observational cohort study of patients with diabetic foot ulcers (DFU) to develop and validate potential tissue-based biomarkers that predict complete wound healing. Eligible and consented participants will begin standard of care treatment after collection of tissue specimens from the wound's edge. An additional tissue specimen is collected at 4 weeks if clinically indicated. Tissues will be tested for c-myc and phosphorylated glucocorticoid receptor (p-GR) levels using validated protocols at a central laboratory. Participants will be followed weekly for up to 12 weeks or until complete wound healing (whichever occurs first). One final assessment 2 weeks after complete wound healing will occur to confirm healing.
